1962 Use bool for boolean.
1963 * region-cache.c (region_cache_forward, region_cache_backward):

1965
19662013-03-08 Dmitry Antipov <dmantipov@yandex.ru>

1975 Adjust call to find_newline.

2005 Adjust comment.
2006 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.

2009 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
2010
20112013-03-07 Eli Zaretskii <eliz@gnu.org>

2031
20322013-03-07 Dmitry Antipov <dmantipov@yandex.ru>

2085
2086 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
2087 * sysdep.c (list_system_processes)
2088 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
2089 Make it a stub in this case; otherwise the build might fail,
2090 and this code hasn't been tested on such hosts anyway.
2091 Problem reported by Nelson H. F. Beebe in
2092 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
2093 and analyzed by Jérémie Courrèges-Anglas in
2094 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
2095
20962013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
2097
2098 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
2099 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
2100 (get_visually_first_element, move_it_vertically_backward): Ajust users.

2103
21042013-03-05 Paul Eggert <eggert@cs.ucla.edu>
2105
2106 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
2107 * filelock.c: Include <c-ctype.h>.
2108 (MAX_LFINFO): New top-level constant.
2109 (lock_info_type): Remove members pid, boot_time. Add members at,
2110 dot, colon. Change user member to be the entire buffer, not a
2111 pointer. This allows us to handle the case where a foreign
2112 pid or boot time exceeds the local range. All uses changed.
2113 (LINKS_MIGHT_NOT_WORK): New constant.
2114 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
2115 (defined_WINDOWSNT): Remove.
2116 (MAKE_LOCK_NAME, file_in_lock_file_name):
2117 Always use .#FILE (not .#-FILE) for the file lock,
2118 even if it is a regular file.
2119 (rename_lock_file): New function.
2120 (create_lock_file): Use it.
2121 (create_lock_file, read_lock_data):
2122 Prefer a symbolic link for the lock file, falling back on a
2123 regular file if symlinks don't work. Do not try to create
2124 symlinks on MS-Windows, due to security hassles. Stick with
2125 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
2126 link, rename, unlink, mkstemp) when creating locks, as a GNUish
2127 host may be using a Windowsish file system, and cannot use
2128 MS-Windows-only system calls. Fall back on mktemp if mkstemp
2129 doesn't work. Don't fail merely because of a symlink-contents
2130 length limit in the current file system; fall back on regular
2131 files. Increase the symlink contents length limit to 8 KiB, this
2132 should be big enough for any real use and doesn't crunch the
2133 stack.
2134 (create_lock_file, lock_file_1, read_lock_data):
2135 Simplify allocation of lock file buffers now that they fit in 8 KiB.
2136 (lock_file_1): Return error number, not bool. All callers changed.
2137 (ELOOP): New macro, if not already defined.
2138 (read_lock_data): Return size of lock file contents, not Lisp object.
2139 All callers changed. Handle a race condition if some other process
2140 replaces a regular-file lock with a symlink lock or vice versa,
2141 while we're trying to read the lock.
2142 (current_lock_owner): Parse contents more carefully, to help avoid
2143 confusing a regular-file lock with some other application's use
2144 of the file. Check for lock file contents being too long, or
2145 not parsing correctly.
2146 (current_lock_owner, lock_file):
2147 Allow foreign pid and boot times that exceed the local range.
2148 (current_lock_owner, lock_if_free, lock_file):
2149 Simplify allocation of lock file contents.
2150 * w32.c (sys_rename_replace): New function, containing most of
2151 the contents of the old sys_rename.
2152 (sys_rename): Use it.
2153 (fchmod): New dummy function.
2154 * w32.h (sys_rename_replace, fchmod): New decls.
2155
21562013-03-05 Eli Zaretskii <eliz@gnu.org>
2157
2158 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
2159 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
2160 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
2161 <dmantipov@yandex.ru>.
2162
21632013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
2164
2165 * composite.c (get_composition_id, fill_gstring_header):
2166 Use make_uninit_vector where appropriate.
2167 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
2168 * xselect.c (clean_local_selection_data): Likewise.
2169
21702013-03-04 Paul Eggert <eggert@cs.ucla.edu>
2171
2172 Fix misuse of ImageMagick that caused core dump (Bug#13846).
2173 * image.c (imagemagick_load_image): Calculate height and width
2174 after flattening the image, not before.
2175
21762013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
2177
2178 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
2179 * ftfont.c (ftfont_shape_by_flt): Likewise.
2180 * w32uniscribe.c (uniscribe_shape): Likewise.
2181
21822013-03-02 Paul Eggert <eggert@cs.ucla.edu>
2183
2184 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
2185 The old approach, which fell back on DIR/.#FILE.0 through
2186 DIR/.#FILE.9, had race conditions that could not be easily fixed.
2187 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
2188 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
2189 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
2190 because the locking mechanism was never reliable in that case).
2191 This patch fixes this and other bugs discovered by a code
2192 inspection that was prompted by
2193 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
2194 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
2195 to avoid interoperability problems between the MS-Windows and
2196 non-MS-Windows implementations. MS-Windows and non-MS-Windows
2197 instances of Emacs now ignore each others' locks.
2198 * filelock.c (defined_WINDOWSNT): New constant.
2199 (MAKE_LOCK_NAME, fill_in_lock_file_name):
2200 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
2201 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
2202 regular files on MS-Windows hosts.
2203 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
2204 Use SAFE_ALLOCA to avoid problems with long file names.
2205 (MAX_LFINFO): Now a local constant, not a global macro.
2206 (IS_LOCK_FILE): Remove.
2207 (lock_file_1): Don't inspect errno if symlink call succeeds;
2208 that's not portable.
2209 (lock_file): Document that this function can return if lock
2210 creation fails.
2211 (lock_file): Don't access freed storage.
2212
22132013-03-02 Andreas Schwab <schwab@linux-m68k.org>
2214
2215 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
2216
22172013-03-02 Paul Eggert <eggert@cs.ucla.edu>
2218
2219 * textprop.c: Use bool for booleans.
2220 (validate_interval_range, Fadd_text_properties)
2221 (Fremove_text_properties): Prefer bool to int when either works.
2222
22232013-03-02 Eli Zaretskii <eliz@gnu.org>
2224
2225 * textprop.c (Fadd_text_properties, Fremove_text_properties):
2226 If the interval tree changes as a side effect of calling
2227 modify_region, re-do processing starting from the call to
2228 validate_interval_range. (Bug#13743)
2229
22302013-02-28 Eli Zaretskii <eliz@gnu.org>
2231
2232 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
2233 (Bug#13546).
2234
22352013-02-27 Eli Zaretskii <eliz@gnu.org>
2236
2237 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
2238 _SH_DENYRW flag, instead of emacs_open, to deny any other process
2239 access to the lock file until it is written and closed.
2240 (Bug#13807)
2241

2243
2244 * callint.c (Qcall_interactively):

2251
22522013-02-26 Paul Eggert <eggert@cs.ucla.edu>
2253
2254 Minor textprop integer cleanup.
2255 * intervals.h, textprop.c (add_text_properties_from_list):
2256 Return void, not int, since nobody uses the return value.
2257 * textprop.c (validate_plist, add_properties, remove_properties)
2258 (Fadd_text_properties):
2259 Don't assume list length fits in int.
2260 (interval_has_all_properties, interval_has_some_properties)
2261 (interval_has_some_properties_list, add_properties, remove_properties)
2262 (Fadd_text_properties, Fremove_text_properties)
2263 (Fremove_list_of_text_properties, text_property_stickiness):
2264 Use bool for booleans.
2265 (Fadd_text_properties, Fremove_text_properties):
2266 (Fremove_list_of_text_properties):
2267 Reindent do-while as per GNU style.
2268
22692013-02-25 Eli Zaretskii <eliz@gnu.org>
2270
2271 Implement CLASH_DETECTION for MS-Windows.
2272
2273 * filelock.c [WINDOWSNT]: Include w32.h.
2274 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
2275 function of that name. Up-case the macro arguments.
2276 (IS_LOCK_FILE): New macro.
2277 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
2278 (create_lock_file): New function, with body extracted from
2279 lock_file_1.
2280 [WINDOWSNT]: Implement lock files by writing a regular file with
2281 the lock information as its contents.
2282 (read_lock_data): New function, on Posix platforms just calls
2283 emacs_readlinkat.
2284 [WINDOWSNT]: Read the lock info from the file.
2285 (current_lock_owner): Call read_lock_data instead of calling
2286 emacs_readlinkat directly.
2287 (lock_file) [WINDOWSNT]: Run the file name through
2288 dostounix_filename.
2289
2290 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
2291 just check if the process by that PID exists.
2292
2293 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
2294 also present, as doing so will fail to error out if the file
2295 already exists.
2296
2297 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
2298
2299 * textprop.c (Fadd_text_properties, Fremove_text_properties)
2300 (Fremove_list_of_text_properties): Skip all of the intervals in
2301 the region between START and END that already have resp. don't
2302 have the requested properties, not just the first one.
2303 Add assertions that the loop afterwards always modifies the
2304 properties. (Bug#13743)
2305
23062013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
2307
2308 * callint.c (Fcall_interactively): Use the right lexical environment

2311
23122013-02-25 Paul Eggert <eggert@cs.ucla.edu>
2313
2314 Simplify data_start configuration (Bug#13783).

2317 (START_FILES): Remove. All uses removed.
2318 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
2319 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
2320 (buildobj.h): Use it.
2321 ($(ALLOBJS)): Depend on globals.h.
2322 (temacs$(EXEEXT)): Use $(ALLOBJS).
2323 * autodeps.mk (ALLOBJS): Move to Makefile.in.
2324 * deps.mk (vm-limit.o):
2325 * makefile.w32-in ($(BLD)/vm-limit.$(O)):
2326 Do not depend on mem-limits.h.
2327 * emacs.c (__do_global_ctors, __do_global_ctors_aux)
2328 (__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__)
2329 [__GNUC__ && !ORDINARY_LINK]: Remove.
2330 * mem-limits.h, pre-crt0.c: Remove.
2331 * unexaix.c, unexcoff.c: Don't include mem-limits.h.
2332 * unexcoff.c (etext): New decl.
2333 (make_hdr): Use DATA_START instead of start_of_data.
2334 * vm-limit.c: Move most of mem-limits.h's contents here.
2335 (data_start): New decl. It's OK if this is approximate,
2336 so simplify-away some unnecessary exactness.
2337 (POINTER): Remove; all uses removed.
2338 (data_space_start): Now char *, to avoid casts.
2339 (exceeds_lisp_ptr): New function, replacing the old
2340 EXCEEDS_LISP_PTR macro. All uses changed.
2341 (check_memory_limits): Simplify and remove casts.
2342 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.
2343 (memory_warnings): Use data_start instead of start_of_data.

2346
2347 * xdisp.c (set_message): Only check for debug-on-message if STRING

2353 * filelock.c (fill_in_lock_file_name): Fix crash caused by the
2354 2012-07-10 patch to this file. Reported by Eli Zaretskii in
2355 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
2356 and diagnosed by Andreas Schwab in
2357 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.

23592013-02-22 Paul Eggert <eggert@cs.ucla.edu>
2360
2361 Assume C89 or better.
2362 * ralloc.c (SIZE, POINTER, NIL):
2363 * vm-limit.c (POINTER):
2364 Remove, replacing all uses with C89 equivalents. These old
2365 symbols were present only for porting to pre-C89 platforms.
2366
23672013-02-22 Claudio Bley <claudio.bley@gmail.com>
2368
2369 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
2370 This avoids warning messages reported as part of Bug#13546.
2371
23722013-02-21 Ken Brown <kbrown@cornell.edu>
2373
2374 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.
2375
23762013-02-20 Stefan Monnier <monnier@iro.umontreal.ca>
2377
2378 * sheap.c (report_sheap_usage): Prefer message1_nolog.
2379
2380 * keyboard.c (Qcommand_execute): New var.
2381 (command_loop_1, read_char): Use it.
2382 (Fcommand_execute): Remove, replace by an Elisp implementation.
2383 (syms_of_keyboard): Adjust accordingly.
2384
23852013-02-19 Daniel Colascione <dancol@dancol.org>
2386
2387 * sheap.c (report_sheap_usage): Use message, not message1, so
2388 that we don't try to create a buffer while we're in the middle
2389 of dumping Emacs. Explain why.
2390
23912013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
2392
2393 * search.c (find_newline): Return byte position in bytepos.
2394 Adjust comment.

2396 Add bytepos argument.
2397 * lisp.h (find_newline, find_next_newline_no_quit)

2404 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
2405
24062013-02-19 Eli Zaretskii <eliz@gnu.org>
2407
2408 * w32proc.c (new_child): Avoid leaking handles if the subprocess
2409 resources were not orderly released.
2410
24112013-02-17 Eli Zaretskii <eliz@gnu.org>
2412
2413 * xdisp.c (x_draw_vertical_border): For a window that is neither
2414 the leftmost nor the rightmost, redraw both the left and the right
2415 vertical borders. (Bug#13723)
2416
24172013-02-17 Stefan Monnier <monnier@iro.umontreal.ca>

2434
24352013-02-16 Eli Zaretskii <eliz@gnu.org>
2436
2437 * w32.c (sys_chown): Remove unused function.
2438
2439 * w32term.c <input_signal_count>: Declare 'volatile'
2440 unconditionally. (Bug#9066)
2441
2442 * w32.c (set_errno): Reset h_errno and don't set it to any other
2443 value. Set errno instead.
2444 (check_errno): Reset h_errno.
2445 (sys_socket, socket_to_fd, sys_bind, sys_connect)
2446 (sys_gethostname, sys_getservbyname, sys_getpeername)
2447 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
2448 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set

2451
24522013-02-15 Paul Eggert <eggert@cs.ucla.edu>
2453
2454 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
2455
24562013-02-15 Eli Zaretskii <eliz@gnu.org>
2457
2458 * keyboard.c (read_char): Fix calculation of auto-save time out
2459 when auto-save-timeout is less than 4. (Bug#13720)
2460
2461 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
2462 time. Improve diagnostics in DebPrint. (Bug#13546)
2463
2464 * w32.c (sys_socket, sys_bind, sys_connect, sys_gethostname)
2465 (sys_gethostbyname, sys_getservbyname, sys_getpeername)
2466 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
2467 (sys_accept, sys_recvfrom, sys_sendto, fcntl): In case of failure,
2468 make sure errno is set to an appropriate value. (Bug#13546)
2469 (socket_to_fd): Add assertion against indexing fd_info[] with a
2470 value that is out of bounds.
2471 (sys_accept): If fd is negative, do not set up the child_process
2472 structure for reading.
2473
24742013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
2475
2476 * composite.c (fill_gstring_header): Remove useless prototype.
2477 Break long line.
2478 * lisp.h (message_dolog, compile_pattern): Adjust prototype.
2479 * print.c (PRINTDECLARE, print_object):
2480 * search.c (compile_pattern, fast_looking_at, search_buffer):
2481 (simple_search, boyer_moore, Freplace_match):
2482 * xdisp.c (c_string_pos, number_of_chars, message_dolog):
2483 (get_overlay_arrow_glyph_row, display_mode_element):
2484 (decode_mode_spec_coding, message3):
2485 * xfaces.c (face_at_string_position): Use bool for booleans.
2486 Adjust comments.
2487
24882013-02-15 Paul Eggert <eggert@cs.ucla.edu>
2489
2490 Fix AIX port (Bug#13650).
2491 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
2492 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
2493 was #undeffed earlier, so it cannot be used as a macro here.
2494 Use the constant and not the macro.
2495
24962013-02-15 Eli Zaretskii <eliz@gnu.org>
2497
2498 * w32proc.c (new_child): If no vacant slots are found in
2499 child_procs[], make another pass looking for slots whose process
2500 has exited or died. (Bug#13546)
2501
2502 * w32.c (sys_pipe): When failing due to file descriptors above
2503 MAXDESC, set errno to EMFILE.
2504 (_sys_read_ahead): Update cp->status when failing to read serial
2505 communications input, so that the status doesn't stay at
2506 STATUS_READ_IN_PROGRESS. (Bug#13546)
2507
25082013-02-14 Jan Djärv <jan.h.d@swipnet.se>
2509
2510 * gtkutil.c (tb_size_cb): New function.
2511 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
2512
25132013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
2514
2515 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
2516 an event.
2517
25182013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
2519
2520 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
2521
25222013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
2523
2524 * font.c (font_range): Add pos_byte argument. Adjust comment
2525 and break long line.
2526 * font.h (font_range): Adjust prototype.
2527 * composite.c (autocmp_chars): Pass byte position to font_range.
2528 Break long line. Remove useless prototype and format comment.
2529
25302013-02-13 Glenn Morris <rgm@gnu.org>
2531
2532 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
2533
25342013-02-13 Paul Eggert <eggert@cs.ucla.edu>
2535
2536 Improve AIX port some more (Bug#13650).
2537 With this, it should be as good as it was in 23.3, though it's
2538 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
2539 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
2540 * unexaix.c (start_of_text): Remove.
2541 (_data, _text): Declare as char[], not int, as AIX manual suggests.
2542 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
2543 (orig_load_scnptr, orig_data_scnptr):
2544 Now off_t, not long, since they are file offsets.
2545 (make_hdr): Use _data, not start_of_data ().
2546 This is the key part of the fix.
2547 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
2548 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
2549
2550 * pre-crt0.c (data_start): Initialize to 1.
2551 This ports to compilers that optimize the external declaration
2552 'int x = 0;' as if it were 'int x;' to shrink the executable.
2553
2554 Improve AIX port (Bug#13650).
2555 This doesn't fix the bug, but it makes progress: Emacs builds now.
2556 * unexaix.c: Include inttypes.h, stdarg.h.
2557 (report_error, report_error_1): Mark as _Noreturn.
2558 (report_error): Don't report the wrong errno.
2559 (report_error_1): Now varargs. All callers changed.
2560 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
2561 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
2562 (write_ptr): Use %p to print address rather than %lx and a cast
2563 to unsigned long. Grow buffer a bit, to be safer.
2564
25652013-02-13 Eli Zaretskii <eliz@gnu.org>
2566
2567 * bidi.c (bidi_resolve_neutral): After finding the next
2568 non-neutral character, accept NEUTRAL_ON type as well, because
2569 directional control characters, such as LRE and RLE, have their
2570 type converted to that by bidi_resolve_weak. This avoids aborts
2571 when LRE/RLE follows a run of neutrals.
2572 (bidi_move_to_visually_next): Assert that return value of
2573 bidi_peek_at_next_level is non-negative. Negative values will
2574 cause an infloop.
2575
25762013-02-13 Paul Eggert <eggert@cs.ucla.edu>
2577
2578 Minor getenv-related fixes.
2579 * callproc.c (Fcall_process_region) [!DOS_NT]:
2580 Avoid unnecessary duplicate call to getenv.
2581 * callproc.c (init_callproc):
2582 * dispnew.c (init_display):
2583 * sysdep.c (sys_subshell):
2584 Omit unnecessary cast of getenv or egetenv.
2585
25862013-02-13 Juanma Barranquero <lekktu@gmail.com>
2587
2588 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
2589 Update dependencies.
2590
25912013-02-12 Eli Zaretskii <eliz@gnu.org>
2592
2593 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
2594 marker's position.
2595 (display_line): Set w->region_showing to the value of
2596 it->region_beg_charpos, not to -1. This fixes redisplay
2597 optimization when cursor is moved up after M->. (Bug#13623)
2598 (Bug#13626)
2599 (try_scrolling): Scroll text up more if point is too close to ZV
2600 and inside the scroll margin. This makes sure point is moved
2601 outside the scroll margin in these cases.
2602
2603 * window.h (struct window): region_showing can no longer be
2604 negative.
2605
26062013-02-11 Paul Eggert <eggert@cs.ucla.edu>
2607
2608 Tune by using memchr and memrchr.
2609 * doc.c (Fsnarf_documentation):
2610 * fileio.c (Fsubstitute_in_file_name):
2611 * search.c (find_newline, scan_newline):
2612 * xdisp.c (pos_visible_p, display_count_lines):
2613 Use memchr and memrchr rather than scanning byte-by-byte.
2614 * search.c (find_newline): Rename from scan_buffer.
2615 Omit first arg TARGET, as it's always '\n'. All callers changed.
2616
2617 Clean up read_key_sequence a tiny bit more.
2618 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
2619 (read_key_sequence): Remove unused locals.
2620
26212013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
2622
2623 Clean up read_key_sequence a bit; reread active keymaps after first event.
2624 * keyboard.c (read_char, read_char_x_menu_prompt)
2625 (read_char_minibuf_menu_prompt):
2626 Replace nmaps+maps with a single `map' arg.
2627 (follow_key): Operate on a single map.
2628 (active_maps): New function.
2629 (test_undefined): Also return true for nil bindings.
2630 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
2631 a single (composed) keymap. Remember `first_event' to choose the right
2632 set of active keymaps. Recompute the set of keymaps after receiving
2633 the first event. Remove GOBBLE_FIRST_EVENT.
2634 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
2635 * keyboard.h (read_char): Update declaration.
2636 * lread.c (read_filtered_event): Adjust call to read_char.
2637
26382013-02-11 Eli Zaretskii <eliz@gnu.org>
2639
2640 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
2641 Don't use the limitation on backwards movement when lines are truncated
2642 in the window. (Bug#13675)
2643
26442013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
2645
2646 * marker.c (set_marker_internal): If desired position is passed
2647 as a marker, avoid call to buf_charpos_to_bytepos.
2648 * window.c (Fset_window_point): Omit redundant type checking.
2649 (Fset_window_start): Likewise. Format comment.
2650 (window_scroll_pixel_based): Use set_marker_restricted_both
2651 with character and byte positions obtained from an iterator.
2652 (Fset_window_configuration): Use set_marker_restricted_both.
2653 * xdisp.c (message_dolog): Likewise.
2654
26552013-02-10 Eli Zaretskii <eliz@gnu.org>
2656
2657 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
2658 When text lines are longer than window's screen lines, don't move back
2659 too far. This speeds up some redisplay operations. (Bug#13675)

2670
26712013-02-09 Paul Eggert <eggert@cs.ucla.edu>
2672
2673 Minor hashing refactoring.
2674 * fns.c (SXHASH_REDUCE): Move to lisp.h.
2675 (sxhash_float): Return EMACS_UINT, for consistency with the other
2676 hash functions.
2677 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
2678 non-static inline function and therefore can't use static vars.
2679 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
2680 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
2681 with the other hash functions.

2684
2685 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
2686 XXXXXX part of the temporary file pattern is not downcased even

2688
2689 * xdisp.c (decode_mode_spec): Remove handling of %t.
2690
2691 * msdos.c (careadlinkatcwd): Remove.
2692
26932013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
2694
2695 * lread.c (skip_dyn_bytes): New function (bug#12598).
2696 (read1): Use it. Use getc instead of READCHAR to read bytes.
2697 (load_each_byte): Remove. Update users.
2698
26992013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
2700
2701 * search.c (scan_buffer): Calculate end byte position just once.
2702 (scan_newline): Do not recalculate start_byte.
2703 (search_command): Use eassert.
2704 * syntax.c (struct lisp_parse_state): New member location_byte.
2705 (scan_sexps_forward): Record from_byte and avoid redundant
2706 character to byte position calculation ...
2707 (Fparse_partial_sexp): ... here. Break too long line.
2708
27092013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
2710
2711 * lisp.h (make_uninit_vector): New function.

2726 * xselect.c (selection_data_to_lisp_data): Use it.
2727
27282013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
2729
2730 * coding.c (Fdefine_coding_system_internal): Use AREF where
2731 argument is known to be a vector.
2732 * fns.c (Flocale_info): Likewise for ASET.
2733 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.

2735
27362013-02-05 Jan Djärv <jan.h.d@swipnet.se>
2737
2738 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
2739 height.

2746 (ns_last_use_native_fullscreen): New variable.
2747 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
2748 (x_set_window_size): Do not take title bar and tool bar into account
2749 if isFullscreen returns YES.
2750 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
2751 (check_native_fs): New function.
2752 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
2753 (ns_term_init): Remove NEW_STYLE_FS.
2754 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
2755 and tool bar if isFullscreen returns NO.
2756 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
2757 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
2758 with HAVE_NATIVE_FS.

2769 (syms_of_nsterm): Add ns-use-native-fullscreen.
2770
27712013-02-04 Paul Eggert <eggert@cs.ucla.edu>
2772
2773 * fileio.c (Qchoose_write_coding_system): Now static.
2774
27752013-02-04 Eli Zaretskii <eliz@gnu.org>
2776
2777 * xdisp.c (window_buffer_changed): region_showing can be negative,
2778 which still means region is being displayed.
2779 (redisplay_internal): Resurrect code that forced redisplay of the
2780 whole window when showing region and the mark has changed.
2781 Record the new mark position to allow redisplay optimizations.
2782 (display_line): If it->region_beg_charpos is non-zero, set the
2783 window's region_showing member to -1. (Bug#13623) (Bug#13626)
2784
2785 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
2786 not bitfield of 1 bit.
2787
27882013-02-03 Daniel Colascione <dancol@dancol.org>
2789
2790 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
2791 daemon mode works on cygw32 when Emacs is installed and not just
2792 during development.
2793
27942013-02-02 Paul Eggert <eggert@cs.ucla.edu>
2795
2796 Avoid file time stamp bug on MS-Windows (Bug#13149).
2797 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
2798 as FAT32 doesn't update time stamps when truncating them.
2799 Also, check that a file time stamp is not a multiple of 100 ns;
2800 this should catch all instances of the problem on MS-Windows,
2801 as its native file system resolution is 100 ns or worse, and
2802 checking for a non-multiple of 100 ns should impose only a small
2803 overhead on systems with ns resolution.
2804
28052013-02-02 Eli Zaretskii <eliz@gnu.org>
2806
2807 Avoid encoding file names on MS-Windows when they need to be run
2808 through dostounix_filename.
2809 * w32.c (normalize_filename): Accept an additional argument
2810 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
2811 downcase it even if w32-downcase-file-names is non-nil.
2812 (dostounix_filename): Accept an additional argument MULTIBYTE and
2813 pass it to normalize_filename.
2814 (emacs_root_dir): Adjust.
2815
2816 * msdos.h (dostounix_filename): Adjust prototype.
2817
2818 * w32.h (dostounix_filename): Adjust prototype.
2819
2820 * msdos.c (dostounix_filename): Accept an additional argument and
2821 ignore it.
2822 (init_environment): Adjust callers of dostounix_filename.
2823
2824 * fileio.c (Ffile_name_directory, file_name_as_directory)
2825 (directory_file_name, Fexpand_file_name)
2826 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
2827 dostounix_filename.
2828 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
2829 non-nil.
2830 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
2831 variables, as egetenv is case-insensitive for DOS_NT.
2832
2833 * dired.c (file_name_completion): Don't call Fdirectory_file_name
2834 with an encoded file name.
2835
2836 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
2837 Adjust calls to dostounix_filename.
2838
2839 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
2840
2841 * unexw32.c (unexec): Adjust call to dostounix_filename.
2842
2843 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
2844
2845 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
2846 dostounix_filename.
2847
2848 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
2849 dostounix_filename.
2850
2851 * callproc.c (Fcall_process): Make sure program name in PATH and
2852 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
2853 is passed to exec/spawnve, which fails unless the file-name
2854 encoding is UTF-8.
2855
2856 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
2857 even if w32-quote-process-args is nil.
2858
28592013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2860
2861 Fix timestamp bug when write-region appends nothing (Bug#13149).
2862 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
2863 the file's time stamp doesn't change if Emacs happens to write nothing
2864 to the file, and on a buggy file system this could cause Emacs to
2865 incorrectly infer that the file system doesn't have the bug.
2866 Avoid this problem by inhibiting the inference in this case.
2867
28682013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
2869
2870 * window.h (struct window): Convert base_line_number, base_line_pos
2871 and column_number_displayed members from Lisp_Object to ptrdiff_t.
2872 Convert region_showing member from Lisp_Object to bitfield.
2873 Remove sequence_number member. Adjust comments.
2874 * window.c (sequence_number): Remove.
2875 (make_window): Initialize column_number_displayed.
2876 * print.c (print_object): Follow the printed representation of
2877 frames and print window pointer to distinguish between windows.
2878 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
2879 * xdisp.c (wset_base_line_number, wset_base_line_pos)
2880 (wset_column_number_displayed, wset_region_showing): Remove.
2881 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
2882 (try_scrolling, try_cursor_movement, redisplay_window)
2883 (try_window_reusing_current_matrix, try_window_id, display_line)
2884 (display_mode_lines, decode_mode_spec): Adjust users.
2885 * .gdbinit (pwinx): Do not print sequence_number.
2886
28872013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2888
2889 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
2890 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
2891 * dired.c: Include <fcntl.h>.
2892 (open_directory): New function, which uses open and fdopendir
2893 rather than opendir. DOS_NT platforms still use opendir, though.
2894 (directory_files_internal, file_name_completion): Use it.
2895 (file_attributes): New function, with most of the old Ffile_attributes.
2896 (directory_files_internal, Ffile_attributes): Use it.
2897 (file_attributes, file_name_completion_stat): First arg is now fd,
2898 not dir name. All uses changed. Use fstatat rather than lstat +
2899 stat.
2900 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
2901 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
2902 (emacs_readlinkat): New function, with much of the old
2903 Ffile_symlink_p, but with an fd argument for speed.
2904 It uses readlinkat rather than careadlinkatcwd, so that it
2905 need not assume the working directory.
2906 (Ffile_symlink_p): Use it.
2907 * filelock.c (current_lock_owner): Use emacs_readlinkat
2908 rather than emacs_readlink.
2909 * lisp.h (emacs_readlinkat): New decl.
2910 (READLINK_BUFSIZE, emacs_readlink): Remove.
2911 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
2912 (emacs_norealloc_allocator, emacs_readlink): Remove.
2913 This stuff is moved to fileio.c.
2914 * w32.c (fstatat, readlinkat): New functions.
2915 (careadlinkat): Don't check that fd == AT_FDCWD.
2916 (careadlinkatcwd): Remove; no longer needed.
2917

2924
29252013-01-30 Eli Zaretskii <eliz@gnu.org>
2926
2927 * w32.c (sys_open): Zero out the flags for the new file descriptor.
2928 (sys_close): Zero out the flags for the file descriptor before
2929 closing it. (Bug#13546)
2930
2931 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
2932 (logon_network_drive, stat_worker, symlink, chase_symlinks):
2933 Use CharNextExA and CharPrevExA to iterate over file names encoded in
2934 DBCS. (Bug#13553)
2935
2936 * w32.c (w32_get_long_filename, init_environment, readlink):
2937 Support file names encoded in DBCS codepages.
2938 (readlink): Use the current file-name-coding-system, not the ANSI
2939 codepage, to decode and handle targets of symlinks.
2940
29412013-01-28 Eli Zaretskii <eliz@gnu.org>
2942
2943 * w32.c (opendir): Now accepts a 'const char *'.
2944
29452013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
2946
2947 Remove obsolete redisplay code. See the discussion at
2948 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
2949 * dispnew.c (preemption_period, preemption_next_check): Remove.
2950 (Vredisplay_preemption_period): Likewise.
2951 (update_frame, update_single_window, update_window, update_frame_1):
2952 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
2953 used, following the 2012-06-22 change.
2954
29552013-01-25 Eli Zaretskii <eliz@gnu.org>
2956
2957 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)

2970 (normalize_filename, readdir): Use it to detect locales where ANSI
2971 encoding of file names uses a double-byte character set (DBCS).
2972 If a DBCS encoding is used, advance by characters using
2973 CharNextExA, instead of incrementing a 'char *' pointer.
2974 Use _mbslwr instead of _strlwr. (Bug#13515)
2975
2976 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
2977 request of memory reservation to 1.7GB. (Bug#13065)

2985
2986 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
2987 Avoid redundant calls to strlen.
2988
29892013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2990
2991 Drop async_visible and async_iconified fields of struct frame.
2992 This is possible because async input is gone; for details, see
2993 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
2994 * frame.h (struct frame): Remove async_visible and async_iconified
2995 members, convert garbaged to unsigned bitfield. Adjust comments.
2996 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
2997 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
2998 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
2999 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
3000 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
3001 * w32term.c: Ditto.
3002 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
3003 properly. Likewise for obscured.
3004 * xterm.c: Ditto.

3006 properly.
3007 * nsterm.m: Ditto.

3013 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
3014
30152013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
3016
3017 * xdisp.c (message2, message2_nolog): Remove functions.
3018 (message3, message3_nolog): Extract nbytes and multibyteness directly
3019 from the string. Change all callers.
3020 (message3_nolog): Don't set message_enable_multibyte since set_message
3021 will reset it anyway.
3022 (message1, message1_nolog): Use message3.
3023 (vmessage): Use a stack allocated buffer rather than f->message_buf.
3024 (with_echo_area_buffer): Remove last two arguments. Update all callers.
3025 (set_message): Drop all but the second arg, which has to be a string.
3026 (set_message_1): Simplify now that we know that a1 is NULL and the
3027 second arg is a string.

3050
3051 * insdel.c (prepare_to_modify_buffer): Force redisplay if

3055
3056 * window.h (struct window): Change window_end_valid member from

3063 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
3064 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
3065 * xdisp.c (check_window_end, reconsider_clip_changes)
3066 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
3067 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)

3069
30702013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
3071
3072 * xdisp.c (mark_window_display_accurate): Simplify the loop
3073 assuming that the only one of vchild, hchild or buffer window
3074 slots is non-nil. Call mark_window_display_accurate_1 for
3075 the leaf windows only.
3076 (mark_window_display_accurate_1): Always assume leaf window.
3077 Adjust comment.
3078
30792013-01-22 Paul Eggert <eggert@cs.ucla.edu>
3080
3081 * emacs.c (Qkill_emacs_hook): Now static.
3082
3083 * fileio.c (Finsert_file_contents): Simplify.
3084 Remove unnecessary assignments and tests.
3085
30862013-01-21 Eli Zaretskii <eliz@gnu.org>
3087
3088 * w32.c (acl_set_file): Don't test for errors unless
3089 set_file_security returns FALSE. Avoids spurious errors when
3090 saving files.
3091
30922013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
3093
3094 * fileio.c (Finsert_file_contents): Revert code introduced at
3095 2013-01-18 in favor of the simpler and generally better fix.
3096 Save stack space by removing 'buffer' and reusing 'read_buf'
3097 where appropriate.
3098
30992013-01-19 Paul Eggert <eggert@cs.ucla.edu>
3100
3101 * lisp.h (eabs): Define unconditionally (Bug#13419).
3102 The old "#if !defined (eabs)" was an unnecessary revenant of back
3103 when this macro was called "abs". Document 'eabs' better.
3104
31052013-01-19 Glenn Morris <rgm@gnu.org>
3106
3107 * fns.c (Frandom): Doc fix.
3108
31092013-01-19 Eli Zaretskii <eliz@gnu.org>
3110
3111 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
3112 segfault when there are lots of overlays.
3113
3114 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
3115 when there are lots of overlays.
3116 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
3117 for the details and a way to reproduce.
3118
31192013-01-19 Paul Eggert <eggert@cs.ucla.edu>
3120
3121 * fileio.c: Use O_APPEND to append.
3122 This corresponds better to the natural interpretation of "append",
3123 and avoids the need to open the output file twice, or to invoke
3124 lseek when APPEND is neither nil nor a number.
3125 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
3126 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
3127 file possibly twice, and lseeking to its end; this avoids the
3128 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
3129 at the same time: the combination is never needed and apparently
3130 it doesn't work with DOS_NT.
3131
3132 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
3133 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
3134
3135 Allow floating-point file offsets.
3136 Problem reported by Vitalie Spinu in
3137 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
3138 * fileio.c (emacs_lseek): Remove.
3139 (file_offset): New function.
3140 (Finsert_file_contents, Fwrite_region): Use it.
3141
31422013-01-19 Chong Yidong <cyd@gnu.org>
3143
3144 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
3145 aborting on Fsignal (Bug#13289).
3146
31472013-01-19 Eli Zaretskii <eliz@gnu.org>
3148
3149 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
3150 set_file_security as failure due to insufficient privileges.
3151 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
3152 (fstat): Return owner and group like 'stat' and 'lstat' do.
3153
31542013-01-19 Paul Eggert <eggert@cs.ucla.edu>
3155
3156 Work around bug in CIFS and vboxsf file systems (Bug#13149).
3157 The bug was observed on Ubuntu operating inside a virtual machine,
3158 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
3159 The workaround introduces a race condition on non-buggy hosts,
3160 but it's an unlikely race and anyway there's a nearly identical
3161 nearby race that can't be fixed.
3162 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
3163 New static vars.
3164 (Fwrite_region): Test for file system time stamp bug.
3165 (init_fileio): New function.
3166 * lisp.h (init_fileio): Declare it.
3167 * emacs.c (main): Call it.
3168
3169 * fileio.c (Finsert_file_contents): Simplify new diagnostic
3170 and make it more consistent with other stat-failure diagnostics.
3171
31722013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
3173
3174 Fix crash when inserting data from non-regular files.
3175 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
3176 for the error description produced by valgrind.
3177 * fileio.c (read_non_regular): Rename to read_contents.
3178 Free Lisp_Save_Value object used to pass parameters.
3179 (read_non_regular_quit): Rename to read_contents_quit.
3180 (Finsert_file_contents): Redesign internal file reading loop to adjust
3181 gap and end positions after each read and so help make_gap to work
3182 properly. Do not signal an I/O error too early and so do not leave
3183 not yet decoded characters in a buffer, which was the reason of
3184 redisplay crash. Use list2 to build return value. Adjust comments.
3185
31862013-01-17 Paul Eggert <eggert@cs.ucla.edu>
3187
3188 Close a race when statting and reading files (Bug#13149).
3189 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
3190 This avoids a race if the file is renamed between stat and open.
3191 This race is not the problem originally noted in Bug#13149;
3192 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
3193
31942013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
3195
3196 * lisp.h (toplevel): Add comment about using Lisp_Save_Value
3197 objects, related functions and macros.

3202 * alloc.c (format_save_value): Rename to make_save_value.
3203 (make_save_pointer): New function.

3226 (non_regular_nbytes): Remove.
3227 (Finsert_file_contents): Convert trytry to ptrdiff_t.
3228 Use format_save_value to pass parameters to read_non_regular.
3229 (read_non_regular): Use XSAVE_ macros to extract parameters.
3230 Adjust comment.
3231 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
3232 format_save_value.
3233 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
3234
32352013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
3236
3237 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
3238 extraction from any Lisp_Save_Value slot. Add type checking.
3239 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
3240 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:

32562013-01-14 Paul Eggert <eggert@cs.ucla.edu>
3257
3258 Avoid needless casts with XSAVE_POINTER.

3273 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
3274 * eval.c (eval_sub): Protect `form' from being GCed before its
3275 car and cdr becomes protected with the backtrace entry.
3276
32772013-01-14 Dmitry Antipov <dmantipov@yandex.ru>

3291 * editfns.c (save_excursion_save): Pack everything within
3292 Lisp_Save_Value and so avoid xmalloc.

3296 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
3297 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
3298 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:

3309
3310 Fix SIGDANGER handlers, for AIX (Bug#13408).
3311 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
3312 Move handlers here from emacs.c; they were out of place.
3313

3332
3333 * nsfont.m (ns_findfonts): Add block/unblock_input calls.

33632013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
3364
3365 Avoid unnecessary byte position calculation for the gap movement.
3366 Since all users of move_gap do CHAR_TO_BYTE for other purposes

3378 New functions.
3379 * term.c (init_tty): Use them instead of rolling our own code.
3380 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
3381 switches from 'signal' to 'pthread_sigmask', which is safer in
3382 multithreaded applications.
3383 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
3384 which has already arranged for that.
3385 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
3386 This is the main part of the bug fix.

3405 left-margin-width, right-margin-width, left-fringe-width,
3406 right-fringe-width, scroll-bar-width and buffer-display-count.
3407 Use Qstringp for default-directory, buffer-file-name,
3408 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
3409 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
3410 line-spacing.
3411 * data.c (store_symval_forwarding): Adjust to call the predicate.

3451 empty (Bug#13255).
3452 (echo_char): Use it.
3453 (read_key_sequence): When echoing mock input, ensure that the
3454 trailing dash is properly added.
3455
34562013-01-05 Eli Zaretskii <eliz@gnu.org>
3457
3458 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
3459 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
3460 digits for buffer positions, before misalignment starts.
3461 Display "0" for integer "object" field.

3495 * term.c (tty_ins_del_lines):
3496 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
3497 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
3498
34992012-12-31 Eli Zaretskii <eliz@gnu.org>
3500
3501 * w32.c (unsetenv): Set up the string passed to _putenv
3502 correctly.
3503 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html

3509
35102012-12-30 Jan Djärv <jan.h.d@swipnet.se>
3511
3512 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
3513 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of
3514 handlebox_widget. Set toolbar_in_hbox to false/true, set
3515 toolbar_is_packed to true.
3516 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
3517 (update_frame_tool_bar): Check toolbar_is_packed for packing.

3522 Check toolbar_is_packed.
3523 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
3524 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
3525 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
3526 false.
3527 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
3528 (xg_update_menubar): Update title only if
3529 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
3530 (xg_update_submenu): Skip tearoff only if
3531 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
3532 (xg_initialize): Initialize xg_detached_menus only if
3533 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
3534
3535 * xterm.h (struct x_output): Surround handlebox_widget with
3536 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
3537 toolbar_in_hbox is bool.
3538
35392012-12-30 Andreas Schwab <schwab@linux-m68k.org>
3540
3541 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
3542 (LIBS_GNUSTEP): Define.
3543 (LIBES): Add $(LIBS_GNUSTEP).
3544 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
3545
35462012-12-30 Eli Zaretskii <eliz@gnu.org>
3547
3548 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
3549 continuation glyph on a TTY with an indication of an empty line.
3550 (Bug#13277)
3551
35522012-12-29 Eli Zaretskii <eliz@gnu.org>
3553
3554 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
3555 file's SELinux context or ACLs successfully set, nil otherwise.
3556 (Bug#13298)
3557 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
3558
3559 * w32proc.c (reader_thread): Avoid passing NULL handles to
3560 SetEvent and WaitForSingleObject.
3561
35622012-12-28 Paul Eggert <eggert@cs.ucla.edu>
3563
3564 Port EXTERNALLY_VISIBLE to Clang 3.2.
3565 * conf_post.h (__has_attribute): New macro.
3566 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
3567
35682012-12-27 Glenn Morris <rgm@gnu.org>
3569
3570 * cygw32.c (Fcygwin_convert_file_name_to_windows)
3571 (Fcygwin_convert_file_name_from_windows): Doc fixes.
3572
35732012-12-27 Eli Zaretskii <eliz@gnu.org>
3574
3575 * fileio.c (file_name_as_directory, directory_file_name):
3576 Accept an additional argument MULTIBYTE to indicate whether the input C
3577 came from a multibyte or a unibyte Lisp string; all callers
3578 adjusted. Don't assume the input string is always multibyte.
3579 (Bug#13262)
3580 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
3581 don't ENCODE_FILE them, and return a unibyte string if the input
3582 was unibyte.
3583 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
3584 don't assume the input strings will always be multibyte. If the
3585 input strings are multibyte, decode strings obtained from C
3586 library functions.
3587
35882012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
3589
3590 * lisp.h (toplevel): Add two notices to the comment about
3591 defining a new Lisp data type.
3592 * print.c (print_object): If Lisp_Save_Value object's pointer
3593 is the address of a memory area containing Lisp_Objects, try
3594 to print them.
3595 * alloc.c (valid_lisp_object_p): Adjust comment.
3596
35972012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
3598
3599 * keyboard.c (record_asynch_buffer_change): Initialize an event
3600 only if it's really needed.
3601 * frame.h (enum output_method): Remove output_mac member since
3602 it's a leftover from the deleted code.
3603 * frame.c (Fframep): Adjust user here ...
3604 * terminal.c (Fterminal_live_p): ... and here.
3605 * coding.c (Qmac): Now here because it's only used to denote
3606 end-of-line encoding type.
3607 (syms_of_coding): DEFSYM it.
3608 * frame.h (Qmac): Remove duplicated declaration.
3609
36102012-12-26 Paul Eggert <eggert@cs.ucla.edu>
3611
3612 * window.c (select_window_1): Now static, since it's used only here.
3613
36142012-12-25 Eli Zaretskii <eliz@gnu.org>
3615
3616 * window.c (window_body_cols): Subtract display margins from the
3617 window body width on TTYs as well. See
3618 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
3619 for the original report.
3620
36212012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
3622
3623 * xdisp.c (redisplay_window): Remove inner local variable
3624 because the outer shadowed one has the same meaning.
3625 * xterm.h (struct x_output): Remove toolbar_detached member since it's
3626 set but never used.
3627 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
3628 (xg_create_tool_bar): Adjust users.
3629
36302012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
3631
3632 * buffer.h (BUF_COMPACT): New macro to follow the common style.
3633 * buffer.c (Fget_buffer_create): Use it to set compact field of
3634 struct buffer_text to avoid accessing an uninitialized value
3635 when compact_buffer is called for the first time.
3636 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
3637 (Fset_buffer_modified_p): Use buffer_window_count to check
3638 whether the buffer is displayed in some window.
3639 * xdisp.c (message_dolog): Likewise.
3640
36412012-12-23 Eli Zaretskii <eliz@gnu.org>
3642
3643 * w32.c (acl_set_file): If setting the file security descriptor
3644 fails, and the new DACL is identical to the existing one, silently
3645 return success. This fixes problems for users backing up their
3646 own files without having the necessary privileges for setting
3647 security descriptors.
3648
3649 * w32proc.c (reader_thread): Do not index fd_info[] with negative
3650 values.
3651 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
3652 after WaitForSingleObject returns normally. This expedites reader
3653 thread shutdown when delete_child triggers it.
3654 (reap_subprocess): More accurate commentary for why we call
3655 delete_child only when cp->fd is negative.
3656
3657 * w32.c (sys_close): Do not call delete_child on a subprocess
3658 whose handle is not yet closed. Instead, set its file descriptor
3659 to a negative value, so that reap_subprocess will call
3660 delete_child on that subprocess when its SIGCHLD arrives.
3661 This avoids closing handles used for communications between sys_select
3662 and reader_thread, which doesn't give sys_select a chance to
3663 notice that the process exited and invoke the SIGCHLD handler for
3664 it.
3665
36662012-12-23 Jan Djärv <jan.h.d@swipnet.se>
3667
3668 * nsfns.m (Fns_do_applescript): Run event loop until script has
3669 been executed (Bug#12969).
3670 (ns_run_ascript): Chech as_script for nil, set to nil after
3671 executing script.
3672
36732012-12-22 Martin Rudalics <rudalics@gmx.at>
3674
3675 * window.c (Fselect_window): Reword doc-string (Bug#13248).
3676
36772012-12-22 Eli Zaretskii <eliz@gnu.org>
3678
3679 * w32term.c (w32fullscreen_hook): New function.
3680 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
3681
36822012-12-21 Eli Zaretskii <eliz@gnu.org>
3683
3684 * fileio.c (Finsert_file_contents): Doc fix.
3685
3686 * w32proc.c (new_child, delete_child, find_child_pid): For a
3687 subprocess, consider its slot being in use as long as its process
3688 handle (procinfo.hProcess) is not NULL. This avoids reusing the
3689 slot when a new process is started immediately after killing
3690 another one, without waiting enough time for the first process to
3691 be reaped and resources allocated for it be orderly freed.
3692 (Bug#13086)
3693 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
3694
36952012-12-21 Chong Yidong <cyd@gnu.org>
3696
3697 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
3698
3699 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
3700
37012012-12-21 Eli Zaretskii <eliz@gnu.org>
3702
3703 * w32.c (get_name_and_id): Always pass NULL as the first argument
3704 of lookup_account_sid. Avoids crashes with UNC file names that
3705 refer to DFS domains, not to specific machine names. (Bug#12621)
3706 Remove now unused argument FNAME; all callers changed.
3707 (get_file_owner_and_group): Remove now unused argument FNAME; all
3708 callers changed.
3709
37102012-12-21 Chong Yidong <cyd@gnu.org>
3711
3712 * editfns.c (Finsert_char): Since read-char-by-name now signals an
3713 error for invalid chars, don't check for a nil return value.
3714
37152012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
3716
3717 Avoid calls to CHAR_TO_BYTE if byte position is known.
3718 * editfns.c (make_buffer_string_both): Use move_gap_both.
3719 (Fbuffer_string): Use make_buffer_string_both.
3720 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
3721 Adjust comment.
3722 (buf_bytepos_to_charpos): Likewise.
3723 (charpos_to_bytepos): Remove.
3724 * fileio.c (Finsert_file_contents): Use move_gap_both.
3725 * search.c (Freplace_match): Likewise.
3726 * process.c (process_send_region): Likewise. Use convenient
3727 names for byte positions.
3728 * lisp.h (charpos_to_bytepos): Remove prototype.
3729 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
3730 * insdel.c (move_gap): Likewise.
3731
37322012-12-20 Paul Eggert <eggert@cs.ucla.edu>
3733
3734 * xdisp.c (redisplay_internal): Remove now-unused local.
3735
37362012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
3737
3738 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
3739 (redisplay_internal): Don't bother selecting the frame to get the
3740 proper value of frame-local variables (bug#13225).
3741
37422012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
3743
3744 * textprop.c (set_text_properties_1): Do not allow NULL interval.
3745 Rename 4th argument since it may be buffer or string. Adjust comment.
3746 * intervals.c (graft_intervals_info_buffer): Find an interval here.
3747
37482012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
3749
3750 * coding.c (Fdetect_coding_region): Do not check start and end with
3751 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
3752 (code_convert_region): Likewise.
3753
37542012-12-18 Eli Zaretskii <eliz@gnu.org>
3755
3756 * w32.c (acl_get_file, acl_set_file): Run the file name through
3757 map_w32_filename, and resolve any symlinks in the file name, like
3758 Posix platforms do.
3759 (acl_set_file): Call revert_to_self, if any privileges were
3760 enabled.
3761
37622012-12-17 Juanma Barranquero <lekktu@gmail.com>
3763
3764 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
3765 ($(BLD)/w32.$(O)): Update dependencies.
3766
37672012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
3768
3769 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
3770 propagate redisplay's scrolling (if any) to the right window.

3772 (display_mode_lines): Complete last fix.
3773 * window.c (select_window_1): New func, extracted from select_window.
3774 (select_window): Use it.

3783 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
3784 (g_b_init_is_valid_security_descriptor)
3785 (g_b_init_set_file_security): New static flags.

3797 (acl_free, acl_get_file, acl_set_file): New functions.
3798
3799 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.

3802
3803 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
3804 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
3805 for some of that bug's symptoms can now cause Emacs to abort.
3806 Remove the workaround.
3807 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
3808 The bug that caused SIGCHLD to get lost has been fixed, and the
3809 workaround for it can now cause Emacs to abort.
3810
38112012-12-16 Paul Eggert <eggert@cs.ucla.edu>
3812
3813 * sysdep.c (emacs_abort): Bump backtrace size to 40.
3814 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
3815 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
3816

3818
3819 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
3820 (Fcopy_file): Change last arg to `preserve_extended_attributes'

3823
3824 * Makefile.in (LIBACL_LIBS): New macro.

38312012-12-15 Eli Zaretskii <eliz@gnu.org>
3832
3833 Fix bug #13079 on MS-Windows with temp files not being deleted.
3834 * w32.h (_child_process): New members input_file and
3835 pending_deletion.
3836 (register_child): First argument is now pid_t.
3837 (record_infile, record_pending_deletion): New prototypes.
3838
3839 * w32proc.c (new_child): Initialize input_file and
3840 pending_deletion members of the child.

3845 (reap_subprocess): Fix a typo in DebPrint string.
3846 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
3847
3848 * fileio.c (internal_delete_file): Return an int again: non-zero
3849 if delete-file succeeds, zero otherwise.
3850
3851 * lisp.h (internal_delete_file): Adjust prototype.
3852
3853 * callproc.c (Fcall_process): Don't overwrite infile with result
3854 of DECODE_FILE.
3855 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
3856 asynchronous subprocess, record the name of the input file name,
3857 if any.
3858 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
3859 delete the file, record it as pending deletion when the subprocess
3860 exits.
3861
38622012-12-14 Eli Zaretskii <eliz@gnu.org>
3863
3864 * editfns.c [HAVE_PWD_H]: Include grp.h.

3869
3870 Fix permissions bugs with setgid directories etc. (Bug#13125)
3871 * dired.c (Ffile_attributes): Return t as the 9th attribute,
3872 to mark it as a placeholder. The old value was often wrong.
3873 The only user of this attribute has been changed to use
3874 file-ownership-preserved-p instead, with its new group arg.
3875 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
3876
38772012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>
3878
3879 * xdisp.c (select_frame_for_redisplay, display_mode_lines):
3880 Keep selected_window and selected_frame in sync.
3881
38822012-12-14 Eli Zaretskii <eliz@gnu.org>
3883
3884 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
3885 try to get accurate owner and group information from NT file
3886 security APIs. This is to make most callers of 'stat' and
3887 'lstat', which don't need that information, much faster.
3888
3889 * dired.c (Ffile_attributes) [WINDOWSNT]:
3890 Set w32_stat_get_owner_group to a non-zero value, to request accurate
3891 owner and group information from 'lstat'.
3892
38932012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3894
3895 * fileio.c (Finsert_file_contents): Don't put tail into head area,
3896 as that confuses set-auto-coding, so insist on the head-read
3897 returning the full 1024 bytes. Let lseek compute the tail offset;
3898 less work for us. Do not ignore I/O errors when reading the tail.
3899
3900 * xdisp.c: Minor style fixes.
3901 (init_iterator): Hoist assignment out of if-expression.

3928 fstat shouldn't fail, and if it does fail copy-file should not proceed.
3929 Remove unnecessary S_ISLNK test, as (contra the comments) this
3930 function can't copy symlinks. Improve quality of error message
3931 when attempting to copy files that are neither regular files nor
3932 directories.

3945 the dumped Emacs is not a sparse file, greatly improving Cygwin
3946 "make bootstrap" performance.

3960 iterator's start_of_box_run_p flag before prepending the stretch.

4017
4018 * emacs.c (main): Call cache_system_info early in startup; we
4019 previously weren't calling it in Cygwin builds.
4020
4021 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK):
4022 Teach the autoconf build system how to compile a Windows resource file

4164 * dbusbind.c (Fdbus_init_bus):
4165 * emacs.c (main):

42332012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
4234
4235 * frame.c (make_frame): Do not set window's buffer to t.
4236 * window.c (Fsplit_window_internal): Likewise. Previously it was
4237 used to indicate that the window is being set up. Now we use
4238 set_window_buffer for all new windows, so the condition in ...
4239 (Fset_window_buffer): ... is always true and can be removed.
4240
42412012-12-07 Dmitry Antipov <dmantipov@yandex.ru>

4252 if the child process is still running. Instead, exit the wait
4253 loop and return zero. (Bug#13086)
4254
42552012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
4256
4257 * frame.h (x_char_width, x_char_height): Remove prototypes.

4271 * callproc.c, process.h (record_kill_process):
4272 New function, containing part of the old call_process_kill.
4273 (call_process_kill): Use it.
4274 This does not change call_process_kill's behavior.
4275 * process.c (Fdelete_process): Use record_kill_process to fix a
4276 race condition that could cause Emacs to lose track of a child.
4277
42782012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
4279
4280 Avoid code duplication between prev_frame and next_frame.
4281 * frame.c (candidate_frame): New function. Add comment.
4282 (prev_frame, next_frame): Use it. Adjust comment.
4283
42842012-12-06 Eli Zaretskii <eliz@gnu.org>
4285
4286 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
4287 fails, signal an error instead of continuing with an empty
4288 string. (Bug#13079)
4289 Encode expanded temp file pattern before passing it to mkstemp or
4290 mktemp.
4291
4292 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
4293 Encode the file name before passing it to dostounix_filename, in
4294 case it will downcase it (under w32-downcase-file-names).
4295 (Bug#12933)
4296
42972012-12-05 Paul Eggert <eggert@cs.ucla.edu>
4298
4299 Minor call-process cleanups.
4300 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
4301 at the same time as other platforms, to simplify analysis.
4302 No need for fd0_volatile since we have synch_process_fd.
4303 Avoid needless emacs_close; arg is always negative.
4304
43052012-12-04 Andreas Schwab <schwab@linux-m68k.org>
4306
4307 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
4308 processes.

4311
4312 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state

4325 Don't let call-process be a zombie factory (Bug#12980).
4326 Fixing this bug required some cleanup of the signal-handling code.
4327 As a side effect, this change also fixes a longstanding rare race
4328 condition whereby Emacs could mistakenly kill unrelated processes,
4329 and it fixes a bug where a second C-g does not kill a recalcitrant
4330 synchronous process in GNU/Linux and similar platforms.
4331 The patch should also fix the last vestiges of Bug#9488,
4332 a bug which has mostly been fixed on the trunk by other changes.
4333 * callproc.c, process.h (synch_process_alive, synch_process_death)
4334 (synch_process_termsig, sync_process_retcode):
4335 Remove. All uses removed, to simplify analysis and so that
4336 less consing is done inside critical sections.
4337 * callproc.c (call_process_exited): Remove. All uses replaced
4338 with !synch_process_pid.
4339 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
4340 These take the role of what used to be in unwind-protect arg.
4341 All uses changed.
4342 (block_child_signal, unblock_child_signal):
4343 New functions, to avoid races that could kill innocent-victim processes.
4344 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
4345 (call_process_kill): Record killed processes as deleted, so that
4346 zombies do not clutter up the system. Do this inside a critical
4347 section, to avoid a race that would allow the clutter.
4348 (call_process_cleanup): Fix code so that the second C-g works again
4349 on common platforms such as GNU/Linux.
4350 (Fcall_process): Create the child process in a critical section,
4351 to fix a race condition. If creating an asynchronous process,
4352 record it as deleted so that zombies do not clutter up the system.
4353 Do unwind-protect for WINDOWSNT too, as that's simpler in the
4354 light of these changes. Omit unnecessary call to emacs_close
4355 before failure, as the unwind-protect code does that.
4356 * callproc.c (call_process_cleanup):
4357 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
4358 * process.c (record_deleted_pid): New function, containing
4359 code refactored out of Fdelete_process.
4360 (Fdelete_process): Use it.
4361 (process_status_retrieved): Remove. All callers changed to use
4362 child_status_change.
4363 (record_child_status_change): Remove, folding its contents into ...
4364 (handle_child_signal): ... this signal handler. Now, this
4365 function is purely a handler for SIGCHLD, and is not called after
4366 a synchronous waitpid returns; the synchronous code is moved to
4367 wait_for_termination. There is no need to worry about reaping
4368 more than one child now.
4369 * sysdep.c (get_child_status, child_status_changed): New functions.
4370 (wait_for_termination): Now takes int * status and bool
4371 interruptible arguments, too. Do not record child status change;
4372 that's now the caller's responsibility. All callers changed.
4373 Reimplement in terms of get_child_status.
4374 (wait_for_termination_1, interruptible_wait_for_termination):
4375 Remove. All callers changed to use wait_for_termination.
4376 * syswait.h: Include <stdbool.h>, for bool.
4377 (record_child_status_change, interruptible_wait_for_termination):
4378 Remove decls.
4379 (record_deleted_pid, child_status_changed): New decls.
4380 (wait_for_termination): Adjust to API changes noted above.
4381
4382 * bytecode.c, lisp.h (Qbytecode): Remove.
4383 No longer needed after 2012-11-20 interactive-p changes.

4440 * alloc.c (xpalloc): Comment fix.
4441 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
4442 and signals an error, do not clear charset_table_size, as
4443 charset_table is still valid.
4444 * doprnt.c (evxprintf): Clear *BUF after freeing it.
4445

4487 Do not assume that fd[0], count, filefd, and save_environ survive
4488 vfork. Fix bug whereby wrong errno value could be reported for
4489 pipe failure. Some minor cleanups, too, as follows. Move buf and
4490 bufsize to the context where they're needed. Change new_argv to
4491 be of type char **, as this is more convenient and avoids casts.
4492 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
4493 Now local constants, not macros.

4729
4730 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
4731 Needed following 2012-10-20 change. (Bug#12902)
4732
47332012-11-18 Juanma Barranquero <lekktu@gmail.com>
4734
4735 * w32proc.c (waitpid): Remove unused label get_result.
4736
47372012-11-17 Juanma Barranquero <lekktu@gmail.com>
4738
4739 * makefile.w32-in (SYSWAIT_H): New macro.
4740 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
4741 ($(BLD)/sysdep.$(O)): Update dependencies.
4742
47432012-11-17 Paul Eggert <eggert@cs.ucla.edu>
4744
4745 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
4746 * callproc.c (relocate_fd): Assume F_DUPFD.
4747 * emacs.c, term.c (O_RDWR): Remove.
4748 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
4749 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
4750 * nsterm.m: Assume <fcntl.h> exists.
4751 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
4752 (create_pty, Fmake_network_process, server_accept_connection)
4753 (wait_reading_process_output, init_process_emacs):
4754 Assume O_NONBLOCK.
4755 (wait_reading_process_output): Put in a special case for WINDOWSNT
4756 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
4757 It's not clear this is needed, but it's a more-conservative change.
4758 (create_process): Assume FD_CLOEXEC.
4759 (create_process, create_pty): Assume O_NOCTTY.
4760 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
4761 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
4762 Omit if not DOS_NT, since F_GETFL is not defined there.
4763 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
4764 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
4765 (O_NOCTTY): Remove.
4766 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
4767 lack it, since gnulib guarantees this.
4768 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
4769
47702012-11-17 Eli Zaretskii <eliz@gnu.org>
4771
4772 * w32.c (faccessat): Pretend that directories have the execute bit
4773 set. Emacs expects that, e.g., in files.el:cd-absolute.
4774
4775 * w32proc.c (create_child): Don't clip the PID of the child
4776 process to fit into an Emacs integer, as this is no longer a
4777 restriction.
4778 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
4779 reaping only the process specified by PID argument, if that is
4780 positive. Use PID instead of dead_child to know which process to
4781 reap. Wait for the child to die only if WNOHANG is not in
4782 OPTIONS.
4783 (sys_select): Don't set dead_child.
4784
4785 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
4786 as it is no longer needed.
4787
4788 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
4789 no longer needed.
4790 (record_child_status_change): Remove the setting of
4791 record_at_most_one_child for the !WNOHANG case.
4792
47932012-11-17 Paul Eggert <eggert@cs.ucla.edu>
4794
4795 Fix problems in ns port found by static checking.
4796 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
4797 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
4798 not to process group.
4799 (ns_select): Use emacs_write, not write, as that's more robust
4800 in the presence of signals.
4801 (fd_handler:): Check for read errors.
4802
48032012-11-16 Glenn Morris <rgm@gnu.org>
4804
4805 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
4806
48072012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
4808
4809 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
4810
48112012-11-16 Eli Zaretskii <eliz@gnu.org>
4812
4813 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
4814 use the same value of thread handle.
4815 (start_timer_thread): If the timer thread exited (due to error),
4816 clean up by closing the two handles it used. Duplicate the caller
4817 thread's handle here, so it gets duplicated only once, when
4818 launching the timer thread. Set priority of the timer thread, not
4819 the caller thread.
4820 (getitimer): Don't duplicate the caller thread's handle here.
4821 (Bug#12832)
4822
48232012-11-16 Jan Djärv <jan.h.d@swipnet.se>
4824
4825 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
4826 called (Bug#12834).
4827
48282012-11-16 Paul Eggert <eggert@cs.ucla.edu>
4829
4830 Remove no-longer-used pty_max_bytes variable.
4831 * process.c (pty_max_bytes): Remove; unused.
4832 (send_process): Do not set it.
4833
48342012-11-15 Juanma Barranquero <lekktu@gmail.com>
4835
4836 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
4837 Update dependencies.
4838
48392012-11-15 Paul Eggert <eggert@cs.ucla.edu>
4840
4841 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
4842 This follows up on the 2012-09-29 patch that removed indirection
4843 for the 'function' field. Reported by Sergey Vinokurov in
4844 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
4845
48462012-11-14 Eli Zaretskii <eliz@gnu.org>
4847
4848 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
4849 different name, as the MS runtime does not have such a function,
4850 and probably never will.) All callers changed. Ignore DIRFD
4851 value if PATH is an absolute file name, to match Posix spec
4852 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
4853 symlinks.
4854
48552012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
4856
4857 * xdisp.c (echo_area_display, redisplay_internal):
4858 Omit redundant check whether frame_garbaged is set.
4859
48602012-11-14 Paul Eggert <eggert@cs.ucla.edu>
4861
4862 Use faccessat, not access, when checking file permissions (Bug#12632).
4863 This fixes a bug that has been present in Emacs since its creation.
4864 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
4865 which must set some sort of record. (Torek's bug report was against
4866 a predecessor of GNU Emacs, but GNU Emacs happened to have the
4867 same common flaw.) See Torek's Usenet posting
4868 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
4869 Posted: Fri Apr 8 14:18:56 1983.
4870 * Makefile.in (LIB_EACCESS): New macro.
4871 (LIBES): Use it.
4872 * callproc.c (init_callproc):
4873 * charset.c (init_charset):
4874 * fileio.c (check_existing, check_executable, check_writable)
4875 (Ffile_readable_p):
4876 * lread.c (openp, load_path_check):
4877 * process.c (allocate_pty):
4878 * xrdb.c (file_p):
4879 Use effective UID when checking permissions, not real UID.
4880 * callproc.c (init_callproc):
4881 * charset.c (init_charset):
4882 * lread.c (load_path_check, init_lread):
4883 Test whether directories are accessible, not merely whether they exist.
4884 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
4885 * fileio.c (check_existing, check_executable, check_writable)
4886 (Ffile_readable_p):
4887 Use symbolic names instead of integers for the flags, as they're
4888 portable now.
4889 (check_writable): New arg AMODE. All uses changed.
4890 Set errno on failure.
4891 (Ffile_readable_p): Use faccessat, not stat + open + close.
4892 (Ffile_writable_p): No need to call check_existing + check_writable.
4893 Just call check_writable and then look at errno. This saves a syscall.
4894 dir should never be nil; replace an unnecessary runtime check
4895 with an eassert. When checking the parent directory of a nonexistent
4896 file, check that the directory is searchable as well as writable, as
4897 we can't create files in unsearchable directories.
4898 (file_directory_p): New function, which uses 'stat' on most platforms
4899 but faccessat with D_OK (for efficiency) if WINDOWSNT.
4900 (Ffile_directory_p, Fset_file_times): Use it.
4901 (file_accessible_directory_p): New function, which uses a single
4902 syscall for efficiency.
4903 (Ffile_accessible_directory_p): Use it.
4904 * xrdb.c (file_p): Use file_directory_p.
4905 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
4906 * lread.c (openp): When opening a file, use fstat rather than
4907 stat, as that avoids a permissions race. When not opening a file,
4908 use file_directory_p rather than stat.
4909 (dir_warning): First arg is now a usage string, not a format.
4910 Use errno. All uses changed.
4911 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
4912 that merely introduced a race.
4913 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
4914 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
4915 and similarly for the other O_* flags.
4916 * w32.c (sys_faccessat): Rename from sys_access and switch to
4917 faccessat's API. All uses changed.
4918 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
4919 (magic_db): Rename from magic_file_p.
4920 (magic_db, search_magic_path): Return an XrmDatabase rather than a
4921 char *, so that we don't have to test for file existence
4922 separately from opening the file for reading. This removes a race
4923 fixes a permission-checking problem, and simplifies the code.
4924 All uses changed.
4925 (file_p): Remove; no longer needed.
4926
49272012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
4928
4929 Omit glyphs initialization at startup.
4930 * dispnew.c (glyphs_initialized_initially_p): Remove.
4931 (adjust_frame_glyphs_initially): Likewise. Adjust users.
4932 (Fredraw_frame): Move actual code from here...
4933 (redraw_frame): ...to here. Add eassert. Adjust comment.
4934 (Fredraw_display): Use redraw_frame.
4935 * xdisp.c (clear_garbaged_frames): Likewise.
4936
49372012-11-13 Eli Zaretskii <eliz@gnu.org>
4938
4939 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
4940 passed to pint2str and pint2hrstr to be at most the size of the
4941 frame's decode_mode_spec_buffer. This avoids crashes with very
4942 large values of FIELD_WIDTH argument to decode_mode_spec.
4943 (Bug#12867)
4944
49452012-11-13 Paul Eggert <eggert@cs.ucla.edu>
4946
4947 Fix a race with verify-visited-file-modtime (Bug#12863).
4948 Since at least 1991 Emacs has ignored an mtime difference of no
4949 more than one second, but my guess is that this was to work around
4950 file system bugs that were fixed long ago. Since the race is
4951 causing problems now, let's remove that code.
4952 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
4953 whose time stamp is off by no more than a second. Insist that the
4954 file time stamps match exactly.
4955
49562012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4957
4958 * frame.h (struct frame): Convert external_tool_bar member to
4959 1-bit unsigned bitfield.
4960 * termhooks.h (struct terminal): Remove mouse_moved member since
4961 all users are long dead. Adjust comment on mouse_position_hook.
4962
49632012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4964
4965 Simplify by using FOR_EACH_FRAME here and there.
4966 * frame.c (next_frame, prev_frame, other_visible_frames)
4967 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
4968 * w32term.c (x_window_to_scroll_bar): Likewise.
4969 * window.c (window_list): Likewise.
4970 * xdisp.c (x_consider_frame_title): Likewise.
4971 * xfaces.c (Fdisplay_supports_face_attributes_p): Likewise.
4972 * xfns.c (x_window_to_frame, x_any_window_to_frame)
4973 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
4974 * xmenu.c (menubar_id_to_frame): Likewise.
4975 * xselect.c (frame_for_x_selection): Likewise.
4976 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
4977 (x_window_to_menu_bar): Likewise.
4978 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
4979
49802012-11-12 Paul Eggert <eggert@cs.ucla.edu>
4981
4982 * data.c (Qdefalias_fset_function): Now static.
4983
4984 Another tweak to vectorlike_header change.
4985 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
4986 Remove, and replace all uses with ...
4987 (next_in_free_list, set_next_in_free_list):
4988 New functions, which respect C's aliasing rules better.
4989
49902012-11-11 Paul Eggert <eggert@cs.ucla.edu>
4991
4992 * window.c (list4i): Rename from 'quad'. All uses changed.
4993 Needed because <sys/types.h> defines 'quad' on Solaris 10.
4994
49952012-11-11 Juanma Barranquero <lekktu@gmail.com>
4996
4997 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
4998 warning about mixing declarations and code in ISO C90.
4999
50002012-11-10 Martin Rudalics <rudalics@gmx.at>
5001
5002 * window.c (Fsplit_window_internal): Set combination limit of
5003 new parent window to t iff Vwindow_combination_limit is t;
5004 fixing a regression introduced with the change from 2012-09-22.
5005 (Fset_window_combination_limit): Fix doc-string.
5006
50072012-11-10 Eli Zaretskii <eliz@gnu.org>
5008
5009 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
5010 amount when the scroll margins are too large. When scrolling
5011 backwards in the buffer, give up if cannot reach point or the
5012 scroll margin within a reasonable number of screen lines.
5013 Fixes point position in window under scroll-up/down-aggressively when
5014 point is positioned many lines beyond the window top/bottom.
5015 (Bug#12811)
5016
5017 * ralloc.c (relinquish): If real_morecore fails to return memory
5018 to the system, don't crash; instead, leave the last heap
5019 unchanged and return. (Bug#12774)
5020
50212012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
5022
5023 * lisp.h (AUTOLOADP): New macro.
5024 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
5025 * data.c (Ffset): Remove special ad-advice-info handling.
5026 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
5027 (Fsubr_arity): CSE.

5033
5034 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
5035
5036 * nsfont.m (Qcondensed, Qexpanded): New variables.
5037 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
5038 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
5039
50402012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
5041
5042 Fix recently introduced crash on MS-Windows (Bug#12839).
5043 * w32term.h (struct scroll_bar): Use convenient header.
5044 (SCROLL_BAR_VEC_SIZE): Remove.
5045 * w32term.c (x_scroll_bar_create): Use VECSIZE.
5046
50472012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
5048
5049 Tweak last vectorlike_header change.
5050 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
5051 vectorlike object on the free list. This is introduced to avoid
5052 some (but not all) pointer casting and aliasing problems, see
5053 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
5054 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
5055 objects.
5056 (xvectype, xvecsize): Use them to examine Lisp_Object values.
5057
50582012-11-09 Jan Djärv <jan.h.d@swipnet.se>
5059
5060 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
5061 been removed, so remove them here also.
5062
50632012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
5064
5065 * doc.c (Fdocumentation): Handle new property
5066 dynamic-docstring-function to replace the old ad-advice-info.
5067
50682012-11-09 Paul Eggert <eggert@cs.ucla.edu>
5069
5070 * fns.c (Qeql, hashtest_eq): Now static.
5071

5078
50792012-11-08 Paul Eggert <eggert@cs.ucla.edu>
5080
5081 Use same hash function for hashfn_profiler as for hash_string etc.
5082 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
5083 * lisp.h (sxhash_combine): New inline function, with the contents
5084 of the old SXHASH_COMBINE.
5085 * profiler.c (hashfn_profiler): Use it, instead of having a
5086 special hash function containing a comparison that always yields 1.
5087
50882012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
5089
5090 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
5091 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
5092 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
5093 Remove unused vars.
5094

5096
5097 * image.c (xpm_make_color_table_h): Fix compiler error because
5098 make_hash_table changed.
5099
51002012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
5101
5102 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
5103
51042012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
5105
5106 Use ad-hoc comparison function for the profiler's hash-tables.
5107 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
5108 (make_log): Use them.
5109 (handle_profiler_signal): Don't inhibit quit any longer since we don't
5110 call Fequal any more.
5111 (Ffunction_equal): New function.
5112 (cmpfn_profiler, hashfn_profiler): New functions.
5113 (syms_of_profiler): Initialize them.
5114 * lisp.h (struct hash_table_test): New struct.
5115 (struct Lisp_Hash_Table): Use it.
5116 * alloc.c (mark_object): Mark hash_table_test fields of hash tables.

5119 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
5120 (hash_lookup, hash_remove_from_table): Move assertion checking of
5121 hashfn result here. Check hash-equality before calling cmpfn.
5122 (Fmake_hash_table): Adjust call to make_hash_table.
5123 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
5124 (syms_of_fns): Initialize them.

51312012-11-08 Eli Zaretskii <eliz@gnu.org>
5132
5133 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
5134 value of w32-scroll-lock-modifier is neither nil nor one of the
5135 known key modifiers. (Bug#12806)
5136
51372012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
5138
5139 Shrink struct vectorlike_header to the only size field.
5140 * lisp.h (enum pvec_type): Avoid explicit enum member values.
5141 Adjust comment.
5142 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
5143 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
5144 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
5145 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
5146 information from the vector header. Adjust comment.
5147 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
5148 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
5149 layout.
5150 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.
5151 (struct vectorlike_header): Remove next member. Adjust comment.
5152 (struct Lisp_Subr): Add convenient header. Adjust comment.
5153 (allocate_pseudovector): Adjust prototype.

5157 (NEXT_IN_FREE_LIST): New macro.
5158 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
5159 (Fmake_bool_vector): Likewise.
5160 (struct large_vector): New type to represent allocation unit for
5161 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
5162 (large_vectors): Change type to struct large_vector.
5163 (allocate_vector_from_block): Simplify.
5164 (PSEUDOVECTOR_NBYTES): Replace with...
5165 (vector_nbytes): ...new function. Adjust users.

5167 (allocate_vectorlike): Likewise.
5168 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
5169 Add easserts. Adjust XSETPVECTYPESIZE usage.
5170 (allocate_buffer): Use BUFFER_PVEC_INIT.
5171 (live_vector_p): Adjust to match large vector.
5172 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
5173 * buffer.h (struct buffer): Add next member.
5174 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
5175 New macros.
5176 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
5177 * fns.c (internal_equal): Adjust to match enum pvec_type change.
5178 (copy_hash_table): Adjust to match vector header change.
5179 * lread.c (defsubr): Use XSETPVECTYPE.
5180 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
5181 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
5182 (xvecsize): New command.
5183
51842012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
5185
5186 * keyboard.c (event_to_kboard): Do not dereference
5187 frame_or_window field of SELECTION_REQUEST_EVENT
5188 and SELECTION_CLEAR_EVENT events (Bug#12814).
5189 * xterm.h (struct selection_input_event): Adjust comment.
5190
51912012-11-07 Eli Zaretskii <eliz@gnu.org>
5192
5193 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
5194 such as Scroll Lock, if the respective keys are treated as
5195 function keys, not as modifiers. This avoids destroying non-ASCII
5196 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
5197
51982012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
5199
5200 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
5201
52022012-11-06 Paul Eggert <eggert@cs.ucla.edu>
5203
5204 Restore some duplicate definitions (Bug#12814).
5205 This undoes part of the 2012-11-03 changes. Some people build
5206 with plain -g rather than with -g3, and they need the duplicate
5207 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
5208 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
5209 Define as macros, as well as as enums or as constants.
5210
52112012-11-06 Jan Djärv <jan.h.d@swipnet.se>
5212
5213 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
5214 to keypad keys (Bug#12816).
5215
52162012-11-06 Paul Eggert <eggert@cs.ucla.edu>
5217
5218 Minor adjustments of recently-changed frame functions.
5219 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
5220 known to be a frame (we're in the FRAMEP branch).
5221 * lisp.h (Qframep): Remove decl. frame.h declares this.
5222 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
5223 since they're meant for Lisp fixnum values.
5224
52252012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
5226
5227 * window.c (Fwindow_combination_limit): Revert to the only
5228 required argument and adjust docstring as suggested in
5229 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
5230 by Martin Rudalics <rudalics@gmx.at>.
5231
52322012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
5233
5234 Widely used frame validity and checking functions.
5235 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
5236 * frame.c (decode_live_frame, decode_any_frame): New functions.
5237 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
5238 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
5239 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)

5242 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
5243 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
5244 (Fframe_focus): Likewise. Allow zero number of arguments.
5245 Adjust docstring.
5246 (frame_buffer_list, frame_buffer_predicate): Remove.
5247 * lisp.h (frame_buffer_predicate): Remove prototype.
5248 * buffer.c (Fother_buffer): Use decode_any_frame.
5249 * xdisp.c (Ftool_bar_lines_needed): Likewise.
5250 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
5251 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
5252 (Fclose_font, Ffont_info): Use decode_live_frame.
5253 * fontset.c (check_fontset_name): Likewise.
5254 * terminal.c (Fframe_terminal): Likewise.
5255 * w32fns.c (check_x_frame): Likewise.
5256 * window.c (Fminibuffer_window, Fwindow_at)
5257 (Fcurrent_window_configuration): Likewise.
5258 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
5259 Likewise. Allow zero number of arguments. Adjust docstring.
5260 * dispnew.c (Fredraw_frame): Likewise.
5261 * xfaces.c (frame_or_selected_frame): Remove.
5262 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
5263 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
5264 (Fframe_face_alist): Use decode_live_frame.
5265 * xfns.c (check_x_frame): Likewise.
5266
52672012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
5268
5269 * window.c (quad): New function.
5270 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
5271 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
5272 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
5273 (Fwindow_line_height): Use it.
5274 (Fwindow_fringes): Use list3.
5275 (Fwindow_scroll_bars): Use list4.
5276 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
5277 (Fwindow_combination_limit): Allow zero number of arguments.
5278
52792012-11-05 Eli Zaretskii <eliz@gnu.org>
5280
5281 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
5282
5283 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
5284 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
5285 file descriptor 2 for standard error. (Bug#12805)
5286
52872012-11-05 Chong Yidong <cyd@gnu.org>
5288
5289 * process.c (wait_reading_process_output): Revert previous change.
5290
52912012-11-05 Paul Eggert <eggert@cs.ucla.edu>
5292
5293 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
5294 This removes code that has been obsolete since around 1990.
5295 * callproc.c (Fcall_process):
5296 * emacs.c (main):
5297 * process.c (create_process):
5298 * term.c (dissociate_if_controlling_tty):
5299 Assume setsid exists.
5300 * callproc.c (child_setup): Assume setpgid exists and behaves as
5301 per POSIX.1-1988 or later.
5302 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
5303 * emacs.c (shut_down_emacs):
5304 * sysdep.c (sys_suspend, init_foreground_group):
5305 Assume getpgrp behaves as per POSIX.1-1998 or later.
5306 * msdos.c (setpgrp): Remove.
5307 (tcgetpgrp, setpgid, setsid): New functions.
5308 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
5309 * term.c (no_controlling_tty): Remove; unused.
5310 * w32proc.c (setpgrp): Remove.
5311 (setsid, tcgetpgrp): New functions.
5312
5313 Simplify by assuming __fpending.
5314 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
5315 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
5316 Do not assume that __fpending's result fits in int.
5317
53182012-11-04 Paul Eggert <eggert@cs.ucla.edu>
5319
5320 Remove EMACS_OUTQSIZE+sleep hack.
5321 * dispnew.c (update_frame_1): Remove hack for terminals slower
5322 than 2400 bps, which throttled Emacs by having it sleep.
5323 This code hasn't worked since at least 2007, when the multi-tty stuff
5324 was added, and anyway those old terminals are long dead.
5325 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
5326 without the dispnew.c change, as dispnew.c doesn't include systty.h.
5327
5328 Fix data-loss with --version (Bug#9574).
5329 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
5330 as we can't assume that emacs_strerror is initialized, and strerror
5331 is good enough here.
5332 (main): Invoke atexit earlier, to catch earlier instances of
5333 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
5334
53352012-11-04 Michael Marchionna <tralfaz@pacbell.net>
5336
5337 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
5338 (keyDown): Remap keypad keys to X11 virtual key codes.
5339
53402012-11-03 Paul Eggert <eggert@cs.ucla.edu>
5341
5342 Fix data-loss with --batch (Bug#9574).
5343 * emacs.c: Include <close-stream.h>.
5344 (close_output_streams): New function.
5345 (main): Pass it to atexit, so that Emacs closes stdout and stderr
5346 and handles errors appropriately.
5347 (Fkill_emacs): Don't worry about flushing, as close_output_stream
5348 does that now.
5349
5350 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
5351 The symptom is a diagnostic "GLib-WARNING **: In call to
5352 g_spawn_sync(), exit status of a child process was requested but
5353 SIGCHLD action was set to SIG_IGN and ECHILD was received by
5354 waitpid(), so exit status can't be returned." The diagnostic
5355 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
5356 The real bug is a race condition between Emacs and glib: Emacs
5357 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
5358 so that glib can't find it. Work around the bug by invoking
5359 waitpid only on subprocesses that Emacs itself creates.
5360 * process.c (create_process, record_child_status_change):
5361 Don't use special value -1 in pid field, as the caller now must
5362 know the pid rather than having the callee infer it.
5363 The inference was sometimes incorrect anyway, due to another race.
5364 (create_process): Set new 'alive' member if child is created.
5365 (process_status_retrieved): New function.
5366 (record_child_status_change): Use it.
5367 Accept negative 1st argument, which means to wait for the
5368 processes that Emacs already knows about. Move special-case code
5369 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
5370 processes that have already been waited for, by testing and
5371 clearing new 'alive' member.
5372 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
5373 now does this internally.
5374 (handle_child_signal): Let record_child_status_change do all
5375 the work, since we do not want to reap all exited child processes,
5376 only the child processes that Emacs itself created.
5377 * process.h (Lisp_Process): New boolean member 'alive'.
5378
5379 Omit duplicate definitions no longer needed with gcc -g3.
5380 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
5381 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
5382 Define only as macros. There's no longer any need to also define
5383 these symbols as enums or as constants, since we now assume
5384 gcc -g3 when debugging.
5385
53862012-11-03 Eli Zaretskii <eliz@gnu.org>
5387
5388 * lisp.mk: Adjust comments to the fact that term/internal is now
5389 loaded from loadup.el.
5390
5391 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
5392 (msdos_fatal_signal): New function.
5393 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
5394 its argument list.
5395
5396 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
5397 for GCC versions before 4.
5398 (emacs_raise): Define to call msdos_fatal_signal.
5399
5400 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
5401 iterator when starting in the middle of a display or overlay
5402 string. (Bug#12745)
5403
54042012-11-03 Chong Yidong <cyd@gnu.org>
5405
5406 * process.c (wait_reading_process_output): Clean up the last
5407 change.
5408
54092012-11-03 Jim Paris <jim@jtan.com> (tiny change)
5410
5411 * process.c (wait_reading_process_output): Avoid a race condition
5412 with SIGIO delivery (Bug#11536).
5413
54142012-11-03 Chong Yidong <cyd@gnu.org>
5415
5416 * buffer.c (cursor_type): Untabify docstring.
5417
54182012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
5419
5420 * frame.h (struct frame): Drop can_have_scroll_bars member
5421 which is meaningless for a long time. Adjust comments.
5422 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
5423 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
5424
54252012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
5426
5427 * window.c (decode_next_window_args): Update window arg after
5428 calling decode_live_window and so fix crash reported at
5429 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
5430 by Juanma Barranquero <lekktu@gmail.com>.
5431 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
5432 * font.c (Ffont_at): Likewise.
5433
54342012-11-01 Jan Djärv <jan.h.d@swipnet.se>
5435
5436 * widget.c (resize_cb): New function.
5437 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
5438 (EmacsFrameResize): Check if all is up to date before changing frame
5439 size.
5440
54412012-11-02 Eli Zaretskii <eliz@gnu.org>

5445 (BACKTRACE_LIMIT_MAX): New macro.
5446 (w32_backtrace): New function.
5447 (emacs_abort): Use w32_backtrace when the user chooses not to
5448 attach a debugger. Update the text of the abort dialog.
5449
54502012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
5451
5452 Window-related stuff cleanup here and there.
5453 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
5454 Use decode_any_window.
5455 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
5456 * xdisp.c (Fformat_mode_line): Likewise.
5457 * font.c (Ffont_at): Use decode_live_window.

5460 (decode_any_window): Remove static.
5461 * window.h (decode_any_window): Add prototype.
5462 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
5463 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
5464 respectively.
5465
54662012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
5467
5468 Remove pad from struct input_event.
5469 * termhooks.h (struct input_event): Remove padding field.
5470 Adjust comment.
5471 * keyboard.c (event_to_kboard): Simplify because frame_or_window
5472 member is never cons for a long time. Adjust comment.
5473 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
5474 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
5475 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
5476 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
5477
54782012-11-01 Eli Zaretskii <eliz@gnu.org>
5479
5480 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
5481
54822012-10-31 Paul Eggert <eggert@cs.ucla.edu>
5483
5484 Fix crash when using Emacs as commit editor for git (Bug#12697).
5485 * callproc.c (setpgrp): Remove macro, as we now use setpgid
5486 and it is configured in conf_post.h.
5487 (Fcall_process): Don't invoke both setsid and setpgid; the former
5488 is enough, if it exists.
5489 * callproc.c (Fcall_process, child_setup):
5490 * process.c (create_process): Use setpgid.
5491 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
5492 for the real thing.
5493 * dispnew.c (init_display): Initialize the foreground group
5494 if we are running a tty display.
5495 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
5496 * lisp.h (init_foreground_group): New decl.
5497 * sysdep.c (inherited_pgroup): New static var.
5498 (init_foreground_group, tcsetpgrp_without_stopping)

55032012-10-31 Michael Albinus <michael.albinus@gmx.de>
5504
5505 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
5506
55072012-10-31 Martin Rudalics <rudalics@gmx.at>
5508
5509 * minibuf.c (read_minibuf): Restore current buffer since
5510 choose_minibuf_frame calling Fset_frame_selected_window may
5511 change it (Bug#12766).
5512
55132012-10-30 Jan Djärv <jan.h.d@swipnet.se>
5514

5516
55172012-10-30 Kenichi Handa <handa@gnu.org>
5518
5519 * font.c (Ffont_at): If WINDOW is specified and it is not
5520 displaying the current buffer, signal an error.
5521
55222012-10-29 Daniel Colascione <dancol@dancol.org>
5523
5524 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
5525 In preparation for fixing bug#12739, move these functions from
5526 here...
5527
5528 * coding.h, coding.c: ... to here, and compile them only when
5529 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
5530 lets us write cygw32-agnostic code for the HAVE_NTGUI case.

5534 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
5535 (timer_loop, getitimer, setitimer): Use it instead of
5536 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
5537 'clock'.
5538 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
5539 literal 10000.
5540
55412012-10-28 Jan Djärv <jan.h.d@swipnet.se>
5542
5543 * nsterm.m (NO_APPDEFINED_DATA): New define.
5544 (last_appdefined_event_data): New variable
5545 (last_appdefined_event): Remove.
5546 (ns_select): Initialize t from last_appdefined_event_data instead
5547 of [last_appdefined_event data1].
5548 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
5549 remove last_appdefined_event (Bug#12698).
5550
55512012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
5552
5553 * frame.c (x_set_font): Catch internal error.
5554
55552012-10-27 Eli Zaretskii <eliz@gnu.org>
5556
5557 Avoid overflow in w32 implementation of interval timers.
5558 When possible, for ITIMER_PROF count only times the main thread
5559 actually executes.
5560 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
5561 'volatile ULONGLONG' types. All the other data which was
5562 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
5563 (GetThreadTimes_Proc): New typedef.
5564 (w32_get_timer_time): New function, returns a suitable time value
5565 for the timer.
5566 (timer_loop): Enter critical section when accessing ULONGLONG
5567 values of the itimer_data struct, as these accesses are no longer
5568 atomic. Call 'w32_get_timer_time' instead of 'clock'.
5569 Remove unused variable.
5570 (init_timers): Initialize s_pfn_Get_Thread_Times.
5571 (start_timer_thread): Don't assign itimer->caller_thread here.
5572 (getitimer): Assign itimer->caller_thread here.
5573 (setitimer): Always call getitimer to get the value of ticks_now.
5574 (sys_spawnve): Avoid compiler warning about format mismatch.
5575
55762012-10-26 Eli Zaretskii <eliz@gnu.org>
5577
5578 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
5579 mouse movement events if the menu bar is active. This avoids
5580 producing a busy "hour-glass" cursor by Windows if the mouse
5581 pointer is positioned over a tooltip shown for some menu item.
5582
55832012-10-25 Paul Eggert <eggert@cs.ucla.edu>
5584
5585 Don't assume process IDs fit in int.
5586 * emacs.c (shut_down_emacs) [!DOS_NT]:
5587 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
5588 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
5589 Use pid_t, not int, to store process IDs, as 'int'
5590 is not wide enough on a few platforms (e.g., AIX and IRIX).
5591
55922012-10-23 Kenichi Handa <handa@gnu.org>
5593
5594 The following change is to make face-font-rescale-alist work
5595 correctly for non-ASCII fonts.
5596
5597 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
5598 (font_open_for_lface): Handle Vface_font_rescale_alist.
5599
56002012-10-23 Chong Yidong <cyd@gnu.org>
5601
5602 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
5603

5606 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
5607 for screen font.
5608 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
5609
5610 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
5611 event (Bug#12681).
5612
56132012-10-21 Glenn Morris <rgm@gnu.org>
5614
5615 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
5616
56172012-10-20 Paul Eggert <eggert@cs.ucla.edu>
5618
5619 Port to OpenBSD 5.1.
5620 * frame.c (Fmouse_position, Fmouse_pixel_position):
5621 * xdisp.c (produce_stretch_glyph):
5622 Declare local vars only when they're needed.
5623 This is clearer and avoids a warning on OpenBSD about unused vars.
5624 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
5625 This is safer, and avoids OpenBSD warnings about unused vars.
5626 * keyboard.c (record_menu_key): Remove unnecessary decl.
5627 (poll_timer): Define only if POLL_FOR_INPUT is defined.
5628 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
5629 as our definition clashes with OpenBSD's.
5630 * xfaces.c (load_face_colors, check_lface_attrs)
5631 (get_lface_attributes_no_remap, get_lface_attributes)
5632 (lface_fully_specified_p, x_supports_face_attributes_p)
5633 (tty_supports_face_attributes_p, face_fontset, realize_face)
5634 (realize_x_face, realize_tty_face):
5635 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
5636 merely Lisp_Object *. This is more informative and avoids
5637 a warning on OpenBSD about accessing beyond an object's size.
5638
56392012-10-20 Chong Yidong <cyd@gnu.org>
5640
5641 * lread.c (Fload): Doc fix (Bug#12592).

5659
56602012-10-18 Jan Djärv <jan.h.d@swipnet.se>
5661
5662 * nsterm.m (ns_select): Check writefds before call to
5663 FD_ISSET (Bug#12668).
5664
56652012-10-18 Daniel Colascione <dancol@dancol.org>
5666
5667 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
5668 (staticpro): If we run out of staticpro slots, die with an
5669 informative error instead of just calling emacs_abort.
5670
56712012-10-18 Martin Rudalics <rudalics@gmx.at>
5672

57912012-10-13 Paul Eggert <eggert@cs.ucla.edu>
5792
5793 Fix some stat-related races.
5794 * fileio.c (Fwrite_region): Avoid race condition if a file is
5795 removed or renamed by some other process immediately after Emacs
5796 writes it but before Emacs stats it. Do not assume that stat (or
5797 fstat) succeeds.
5798 * image.c (slurp_file): Resolve the file name with fopen + fstat
5799 rather than stat + fopen.
5800 (pbm_read_file) [0]: Remove unused code with stat race.

5826
5827 * fileio.c (check_existing): New function.
5828 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it

5833 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
5834

5872 Use bool for booleans.
5873 * lread.c (safe_to_load_version): Rename from safe_to_load_p,
5874 as it's not a predicate. All uses changed. Omit unnecessary
5875 buffer termination.
5876
58772012-10-11 Dmitry Antipov <dmantipov@yandex.ru>
5878

5924 * keyboard.c (timers_run, swallow_events)
5925 (detect_input_pending_run_timers):
5926 * process.c (wait_reading_process_output):
5927 Use unsigned for counter where wraparound-on-overflow is desired,
5928 since unsigned is guaranteed to have that behavior and signed is not.
5929 (read_char): Use ptrdiff_t for string length.
5930 (get_input_pending): Remove first argument, since it was always
5931 the same pointer-to-int (now pointer-to-boolean) &input_pending,

5933 input_pending. All callers changed.
5934 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
5935 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
5936 a string length.
5937 * keymap.c (push_key_description): Omit last arg, which was always 1.
5938 All callers changed.
5939
5940 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.

5951 initializer for PVEC_NORMAL_VECTOR.
5952
59532012-10-10 Paul Eggert <eggert@cs.ucla.edu>
5954

5956 * termopts.h (flow_control, meta_key): Remove unused decls.
5957 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
5958 Don't include termopts.h.
5959
59602012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
5961
5962 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
5963
59642012-10-10 Paul Eggert <eggert@cs.ucla.edu>
5965

59682012-10-09 Jan Djärv <jan.h.d@swipnet.se>
5969

5976
5977 * w32fns.c (w32_last_error): Change the return value to DWORD, to
5978 match what GetLastError returns. Explain why the function is
5979 needed.
5980
5981 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
5982 'is_tooltip_frame', to avoid confusion with its global namesake.
5983
59842012-10-08 Daniel Colascione <dancol@dancol.org>
5985
5986 * xdisp.c (start_hourglass): Call w32_note_current_window when
5987 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
5988 build that caused Emacs to display the hourglass cursor forever.
5989
5990 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
5991 which is broken under remote desktop, calculate the number of
5992 colors available for a display based on the display's number of
5993 planes and number of bits per pixel per plane. (bug#10397).
5994
59952012-10-08 Jan Djärv <jan.h.d@swipnet.se>
5996
5997 * nsfont.m (Vfonts_in_cache): New variable.
5998 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
5999 are used. Add cached fonts to Vfonts_in_cache.
6000 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
6001
60022012-10-08 Juanma Barranquero <lekktu@gmail.com>
6003
6004 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
6005 in nt/config.nt.
6006 (FONT_H): Define after FRAME_H.
6007 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
6008 Update dependencies.
6009
6010 * w32term.c: Remove leftover declaration of keyboard_codepage.
6011
60122012-10-08 Eli Zaretskii <eliz@gnu.org>
6013
6014 * makefile.w32-in (FONT_H): Add $(FRAME_H).
6015 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
6016 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
6017 (GLOBAL_SOURCES): Add cygw32.c.
6018 ($(BLD)/unexw32.$(O)):
6019 ($(BLD)/w32.$(O)):
6020 ($(BLD)/w32console.$(O)):
6021 ($(BLD)/w32fns.$(O)):
6022 ($(BLD)/w32heap.$(O)):
6023 ($(BLD)/w32menu.$(O)):
6024 ($(BLD)/w32proc.$(O)): Add w32common.h.
6025
6026 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
6027 'const char *'.
6028 (x_to_w32_color): Don't modify the argument, modify a copy instead.
6029
60302012-10-08 Daniel Colascione <dancol@dancol.org>
6031
6032 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
6033 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
6034 accidental message numbering hole. Change other messages to
6035 match.
6036
6037 * w32select.h (HAVE_W32SELECT): Remove.
6038
6039 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
6040 w32common.h instead of w32heap.h.
6041
6042 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
6043 (get_allocation_unit, get_processor_type, get_w32_major_version)
6044 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
6045 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
6046 (OS_NT, os_subtype, cache_system_info): Move declarations to
6047 w32common.
6048
6049 * w32heap.c: Include w32common.h.
6050 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
6051 (w32_minor_version, w32_build_number, w32_subtype):
6052 Remove duplicate definitions.
6053
6054 * w32fns.c: Include w32common.h; include w32heap.h only in
6055 WINDOWSNT.
6056
6057 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
6058 Use `report_file_error' instead of `error' in order to better
6059 inform users of what went wrong. Increase NTGUI_UNICODE file
6060 dialog box file name length to 32k, the maximum allowed by the NT
6061 kernel.
6062
6063 * w32common.h: New file.
6064 (ROUND_UP, ROUND_DOWN, get_page_size)
6065 (get_allocation_unit, get_processor_type, get_w32_major_version)
6066 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
6067 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
6068 (OS_NT, os_subtype, cache_system_info): Move here.
6069
6070 * unexw32.c, unexcw.c: Include w32common.h.
6071
6072 * emacs.c (main): Use (defined (WINDOWSNT) || defined
6073 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
6074 to call syms_of_w32select.
6075
6076 * cygw32.h: Remove obsolete EXFUN declarations.
6077
6078 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
6079
6080 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
6081 of w32inevt.o from SOME_MACHINE_OBJECTS.
6082
60832012-10-08 Daniel Colascione <dancol@dancol.org>
6084
6085 * image.c: Permanent fix for JPEG compilation issue --- limit
6086 jpeglib `boolean' redefinition to Cygwin builds.
6087
60882012-10-08 Eli Zaretskii <eliz@gnu.org>
6089
6090 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
6091
6092 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
6093 Cygwin.
6094
60952012-10-08 Daniel Colascione <dancol@dancol.org>
6096
6097 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
6098 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
6099 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
6100 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
6101 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
6102 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
6103 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
6104 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
6105 now a supported configuration.
6106
6107 * Makefile.in: consolidate image variables into LIBIMAGE; add
6108 W32_OBJ and W32_LIBS. Compile new files.
6109
6110 * conf_post.h:
6111 (_DebPrint) declare tracing facility for W32 debugging. We need
6112 to unify tracing later.
6113
6114 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
6115 unconditional use of W32 Unicode functions. Cygwin runs only on
6116 100% Unicode operating systems.
6117
6118 * cygw32.c: New file. Define Cygwin-specific facilities.
6119 (Fcygwin_convert_path_to_windows)
6120 (Fcygwin_convert_path_from_windows): New user functions for
6121 accessing Cygwin path-munging routines.
6122
6123 * cygw32.h: New file.
6124 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
6125 UTF-16LE strings temporarily inside non-Lisp-visible string
6126 objects.
6127
6128 (w32_strerror): Just what it says on the tin.
6129
6130 * emacs.c: Make the NS fork-then-exec code for daemon-launching
6131 also run for Cygwin; both systems have the same problem with using
6132 GUI facilities in a forked child. Also call syms_of_cygw32,
6133 syms_of_w32select in correct places.
6134
6135 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
6136 needs fork-then-exec for daemon launching.
6137
6138 * font.h: Include frame.h.
6139
6140 * image.c: Use the image library cache machinery only when we're
6141 compiling for native WINDOWSNT; Cygwin can use shared libraries
6142 like any other Unixlike system.
6143
6144 * keyboard.c: Clarify a comment regarding the input loop.
6145
6146 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
6147 functions directly instead of trying to detect at runtime that our
6148 host operating system supports them. We make this change for two
6149 reasons: Cygwin lacks support for the multibyte character
6150 conversion functions used by the legacy menu code, and Cygwin
6151 never needs to rely on non-Unicode APIs.
6152
6153 * unexw32.c (hinst): Declare extern.
6154
6155 * w32.c: Change header order;
6156 (w32_strerror): Move to w32fns.c because we need it for
6157 non-WINDOWSNT builds.
6158
6159 * w32.h: Add #error macro to make sure we don't include w32.h for
6160 Cygwin builds. Remove w32select declarations.
6161
6162 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
6163 w32fns.c. w32console.c is WINDOWSNT-only.
6164
6165 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
6166 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
6167 POSIXy alternative.
6168 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
6169 (w32_major_version, w32_minor_version, w32_build_number)
6170 (os_subtype, sound_type): Define here
6171 (w32_defined_color): Make color parameter const for consistency
6172 with other _defined_color functions.
6173 (w32_createwindow): Unconditionally call w32_init_class instead of
6174 doing so only when hprevinst is non-NULL. Plumbing hprevinst
6175 through the code is complex and unnecessary because class
6176 registration is practically free.
6177 (w32_name_of_message): New EMACSDEBUG-only function.
6178 (Fset_message_beep): Move here
6179 (Fx_open_connection): Require that the display name for Windows be
6180 "w32" for consistency, emacsclient disambiguation, and maybe, one
6181 day, multi-window-system support.
6182 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
6183 Cygwin files for W32 GUI facilities, since these clearly don't
6184 expect Cygwin names.
6185 (_DebPrint): Define.
6186 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
6187 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
6188 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
6189 (w32_last_error): Remove.
6190
6191 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
6192
6193 * w32heap.c (syspage_mask): Declare here.
6194 (cache_system_info): Remove.
6195
6196 * w32inevt.c (faked_key): Define globally, not statically.
6197 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
6198 (w32_console_toggle_lock_key): Move to w32fns.c.
6199
6200 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
6201
6202 * w32proc.c (_DebPrint): Move to w32fns.c.
6203 * w32select.c: Include string.h, stdio.h for Cygwin.
6204 * w32select.h: New File.
6205
6206 * w32term.c: Include io.h for non-CYGWIN builds; needed for
6207 get_osfhandle.
6208 (w32_message_fd): New variable. Under Cygwin, holds the file
6209 descriptor the system used to tell us about pending thread
6210 messages.
6211
6212 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
6213 that prevented compilation under non-WINDOWSNT systems.
6214
6215 (w32_initialize): Open /dev/windows and assign it to
6216 w32_message_fd. Provide w32 feature.
6217
6218 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
6219 (WM_EMACS_INPUT_READY): add.
6220 (prepend_msg, w32_message_fd): Declare globally.
6221
6222 * w32xfns.c:
6223 (keyboard_handle): Use only when WINDOWSNT.
6224 (notify_msg_ready): New function. Posts a message to the main
6225 thread's message queue under CYGWIN, which wakes up the main
6226 thread from select(2) by making the /dev/windows file descriptor
6227 ready. Under WINDOWSNT, it sets an event the same way the old
6228 code did.
6229
6230 (post, prepend_msg): Actually call notify_msg_ready instead of
6231 setting the input event directly.
6232
62332012-10-07 Eli Zaretskii <eliz@gnu.org>
6234
6235 * ralloc.c (relinquish): If a heap is ready to be relinquished,
6236 but it still has blocs in it, don't return it to the system,
6237 instead of aborting. (Bug#12402)
6238
62392012-10-07 Jan Djärv <jan.h.d@swipnet.se>
6240
6241 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
6242
6243 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
6244 MAC_OS_X_VERSION_10_6.
6245 (syms_of_nsterm): Remove comment about Panther and above for
6246 ns-antialias-text.
6247 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
6248 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
6249 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
6250
6251 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
6252 MAC_OS_X_VERSION_10_4.

6259 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
6260 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
6261
6262 * nsterm.m (ns_in_resize): Remove (Bug#12479).
6263 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
6264 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
6265 Remove ns_in_resize check.
6266 (ns_clear_frame_area): Remove resize handle code.
6267
6268 * nsfns.m (ns_in_resize): Remove.
6269 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
6270 Remove ns_in_resize check.
6271
62722012-10-07 Paul Eggert <eggert@cs.ucla.edu>
6273
6274 Improve sys_siglist detection.
6275 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
6276 defined as a macro, as is done in Solaris.
6277 (sys_siglist_entries): New macro.
6278 (save_strsignal): Use it.
6279 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
6280 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
6281
62822012-10-06 Jan Djärv <jan.h.d@swipnet.se>
6283
6284 * nsfns.m (Fx_create_frame): Call x_default_parameter with
6285 fullscreen/Fullscreen.
6286
6287 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
6288 tobar_height is new.
6289
6290 * nsterm.m (x_make_frame_visible): Check for fullscreen.
6291 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
6292 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.

6294 Capitalize word in comment. Remove incorrect comment.
6295 (initFrameFromEmacs:): tbar_height renamed tibar_height.
6296 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
6297 error in drawing background.
6298 (toggleFullScreen:): Remove comment. Rearrange calls.
6299 Set toolbar values to zero, save old height in tobar_height.
6300 Restore tool bar height when leaving fullscreen.
6301 (canBecomeMainWindow): New function.
6302
63032012-10-06 Paul Eggert <eggert@cs.ucla.edu>
6304
6305 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
6306
63072012-10-05 Eli Zaretskii <eliz@gnu.org>
6308
6309 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
6310
6311 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
6312 that time stamps of directories could also be changed.
6313 Don't request the too broad GENERIC_WRITE, only the more restrictive
6314 FILE_WRITE_ATTRIBUTES access rights.
6315
6316 * fileio.c (Fset_file_times): Special-case ignoring errors for
6317 directories only on MSDOS, not on MS-Windows.
6318
63192012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
6320
6321 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
6322
63232012-10-04 Eli Zaretskii <eliz@gnu.org>
6324
6325 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
6326 see whether CreateFile failed.
6327
63282012-10-04 Paul Eggert <eggert@cs.ucla.edu>
6329
6330 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
6331 to avoid similar races.
6332 * keyboard.c (pending_signals): Now bool, not int.
6333
6334 Port timers to OpenBSD, plus check for timer failures.
6335 OpenBSD problem reported by Han Boetes.
6336 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
6337 and/or setitimer.
6338 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
6339 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
6340 like OpenBSD, which has timer_settime but does not declare it.
6341 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
6342 whether to use itimerspec-related primitives. All uses of
6343 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
6344
63452012-10-02 Paul Eggert <eggert@cs.ucla.edu>
6346
6347 * profiler.c (handle_profiler_signal): Fix a malloc race
6348 that caused Emacs to hang on Fedora 17 when profiling Lisp.

63542012-10-02 Eli Zaretskii <eliz@gnu.org>
6355
6356 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
6357 consistent with the change in return value of 'safe_strsignal'.
6358
63592012-10-02 Paul Eggert <eggert@cs.ucla.edu>
6360
6361 Prefer plain 'static' to 'static inline' (Bug#12541).
6362 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
6363 (bidi_set_sor_type, bidi_push_embedding_level)
6364 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
6365 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
6366 (bidi_cache_search, bidi_cache_ensure_space)
6367 (bidi_cache_iterator_state, bidi_cache_find)

6372
6373 Count overruns when profiling; change units to ns.
6374 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
6375 Give extra weight to samples after overruns, to attempt to count
6376 the time more accurately.
6377 (setup_cpu_timer): Change sampling interval units from ms to ns, since
6378 the underlying primitives nominally do ns.
6379 (Fprofiler_cpu_start): Document the change. Mention that
6380 the sampling intervals are only approximate.

6400 Fix a malloc race condition involving strsignal.
6401 A signal can arrive in the middle of a malloc, and Emacs's signal
6402 handler can invoke strsignal, which can invoke malloc, which is
6403 not portable. This race condition bug makes Emacs hang on GNU/Linux.
6404 Fix it by altering the signal handler so that it does not invoke
6405 strsignal.
6406 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
6407 * process.c (status_message): Use const pointer, in case strsignal
6408 is #defined to safe_strsignal.
6409 * sysdep.c (sys_siglist, init_signals): Always define and
6410 initialize a substitute sys_siglist if the system does not define
6411 one, even if HAVE_STRSIGNAL.
6412 (safe_strsignal): Rename from strsignal. Always define,
6413 using sys_siglist. Return a const pointer.
6414 * syssignal.h (safe_strsignal): New decl.
6415 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
6416
64172012-10-01 Eli Zaretskii <eliz@gnu.org>
6418
6419 * w32proc.c (timer_loop): Fix code that waits for timer
6420 expiration, to avoid high CPU usage.
6421
64222012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
6423
6424 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
6425 (sweep_weak_table): Remove redundant prototypes.
6426
64272012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
6428
6429 * emacs.c: Move the inclusion of TERM_HEADER after including
6430 windows.h on WINDOWSNT. This avoids compilation problems with
6431 MSVC.
6432
64332012-10-01 Eli Zaretskii <eliz@gnu.org>
6434
6435 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
6436 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
6437 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
6438 as the previous version used 'void *'.
6439
6440 * ralloc.c (ROUNDUP): Fix last change.
6441 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
6442 'size_t'.
6443
6444 * w32proc.c <disable_itimers>: New static flag.
6445 (init_timers): Initialize it to zero, after creating the critical
6446 sections used by the timer threads.
6447 (term_timers): Set to 1 before deleting the critical sections.
6448 (getitimer, setitimer): If disable_itimers is non-zero, return an
6449 error indication without doing anything. Reported by Fabrice
6450 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
6451 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
6452 return results.
6453 [!HAVE_SETITIMER]: Behave as the previous version that didn't
6454 support timers.
6455
6456 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
6457 term_ntproc after all the other bookkeeping, to get timers working
6458 as long as possible.
6459
64602012-10-01 Paul Eggert <eggert@cs.ucla.edu>
6461
6462 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
6463 Suggested by Juri Linkov in
6464 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
6465
6466 Prefer plain 'static' to 'static inline' (Bug#12541).
6467 With static functions, modern compilers inline pretty well by
6468 themselves; advice from programmers often hurts as much as it helps.
6469 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
6470 this change shrinks the text size of the Emacs executable by 1.1%
6471 without affecting CPU significantly in my benchmark.
6472 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

6552 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
6553
6554 Revert the FOLLOW-SYMLINKS change for file-attributes.
6555 Doing it right would require several changes to Tramp, and there's

6629 hosts.
6630
6631 * image.c (x_bitmap_pixmap): Return ptrdiff_t, not int, since
6632 'bitmaps' is a pointer.

6767 cpu_log is a hash-table if garbage collecting, since it
6768 doesn't matter in that case.
6769 (deliver_profiler_signal): Rename from sigprof_handler,
6770 for consistency with other handlers.
6771 (setup_cpu_timer): New function, with much of what used to be in
6772 Fprofiler_cpu_start. Check for out-of-range argument.
6773 Prefer timer_settime if available, and prefer
6774 thread cputime clocks, then process cputime clocks, then
6775 monotonic clocks, to the old realtime clock. Use make_timeval
6776 to round more-correctly when falling back to setitimer.
6777 (Fprofiler_cpu_start): Use it.
6778 (Fprofiler_cpu_stop): Prefer timer_settime if available.
6779 Don't assume that passing NULL as the 2nd argument of setitimer
6780 is the same as passing a pointer to all-zero storage.
6781 Ignore SIGPROF afterwards.
6782 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
6783 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
6784 non-fatal signal handlers. Ignore SIGPROF on startup.
6785 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
6786 in profiler.c, since sysdep.c now uses it.
6787
6788 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
6789 Suggested by Eli Zaretskii in
6790 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

6827 (LIBES): Add it.
6828 * atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):

6843 * charset.c, charset.h (maybe_unify_char): Now static.
6844 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
6845 Since this stuff is now private to charset.c, there's no need for
6846 a public macro and no need to inline by hand.

6913
6914 * w32proc.c (sys_signal): Handle all signals defined by the
6915 MS-Windows runtime, not just SIGCHLD. Actually install the signal
6916 handlers for signals supported by Windows. Don't override
6917 term_ntproc as the handler for SIGABRT.
6918 (sigaction): Rewrite to call sys_signal instead of duplicating its
6919 code.
6920 (sys_kill): Improve commentary.
6921
6922 * w32.c (term_ntproc): Accept (and ignore) one argument, for
6923 consistency with a signature of a signal handler. All callers
6924 changed.
6925 (init_ntproc): Accept an argument DUMPING. If dumping, don't
6926 install term_ntproc as a signal handler for SIGABRT, as that
6927 should be done by the dumped Emacs.
6928
6929 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
6930
6931 * w32select.c (term_w32select): Protect against repeated
6932 invocation by setting clipboard_owner to NULL after calling
6933 DestroyWindow.
6934
6935 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
6936 and term_ntproc to their modified signatures.
6937
6938 * character.c (char_string, string_char): Remove calls to
6939 MAYBE_UNIFY_CHAR. See the discussion starting at
6940 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html

6957 * image.c: Omit unnecessary static decls.
6958 (x_create_bitmap_mask, x_build_heuristic_mask):

6996 Move pid_t related decls out of lisp.h.
6997 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
6998 (interruptible_wait_for_termination):
6999 Move these decls from lisp.h to syswait.h, since they use pid_t.
7000 Needed on FreeBSD; see Herbert J. Skuhra in
7001 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
7002 * callproc.c: Include syswait.h.

70482012-09-23 Eli Zaretskii <eliz@gnu.org>
7049
7050 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
7051 fatal_error_backtrace.
7052
7053 * w32proc.c (sys_kill): Undo last change: don't do anything when
7054 invoked to deliver SIGABRT to our own process. This is now
7055 handled by emacs_raise.
7056
70572012-09-23 Juanma Barranquero <lekktu@gmail.com>
7058
7059 * w32term.c (w32_read_socket): Remove leftover reference to
7060 interrupt_input_pending.
7061
70622012-09-23 Paul Eggert <eggert@cs.ucla.edu>

7064 Do not use SA_NODEFER.
7065 Problem reported by Dani Moncayo in
7066 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
7067 * alloc.c (die):
7068 * sysdep.c (emacs_abort): Do not reset signal handler.
7069 * emacs.c (terminate_due_to_signal): Reset signal handler here.
7070 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
7071 wanted even on POSIXish hosts, and it doesn't work on Windows.
7072
70732012-09-23 Jan Djärv <jan.h.d@swipnet.se>
7074
7075 * xterm.c (x_term_init): Call fixup_locale before and after calling
7076 gtk_init (Bug#12392).
7077
70782012-09-23 Chong Yidong <cyd@gnu.org>
7079
7080 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
7081 Vdynamic_library_alist.
7082
7083 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
7084 (Fgnutls_available_p): Caller changed.
7085
7086 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
7087 (Flibxml_parse_xml_region): Likewise.
7088
7089 * dispextern.h (struct image_type): Remove arg from init function.
7090
7091 * image.c (Finit_image_library, lookup_image_type)
7092 (define_image_type): Remove now-unneeded second arg.
7093 (init_xpm_functions, init_png_functions, init_jpeg_functions)
7094 (init_tiff_functions, init_gif_functions, init_svg_functions):
7095 Arglist and w32_delayed_load calling convention changed.

7097 (valid_image_p, make_image): Fix caller to lookup_image_type.
7098
70992012-09-23 Paul Eggert <eggert@cs.ucla.edu>
7100
7101 Simplify and avoid signal-handling races (Bug#12471).
7102 * alloc.c (die):
7103 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
7104 Avoid recursive loop if there's a fatal error in the function itself.
7105 * atimer.c (pending_atimers):
7106 * blockinput.h: Don't include "atimer.h"; no longer needed.
7107 (interrupt_input_pending): Remove. All uses removed.
7108 pending_signals now counts both atimers and ordinary interrupts.
7109 This is less racy than having three separate pending-signal flags.
7110 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
7111 (input_blocked_p):
7112 Rename from their upper-case counterparts BLOCK_INPUT,
7113 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
7114 INPUT_BLOCKED_P, and turn into functions. All uses changed.
7115 This makes it easier to access volatile variables more accurately.
7116 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
7117 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
7118 that's more reliable if the code is buggy and sets
7119 interrupt_input_blocked to a negative value. All uses changed.
7120 * atimer.c (deliver_alarm_signal):
7121 Remove. No need to deliver this to the parent; any thread can
7122 handle this signal now. All uses replaced by underlying handler.
7123 * atimer.c (turn_on_atimers):
7124 * dispnew.c (handle_window_change_signal):
7125 * emacs.c (handle_danger_signal):
7126 * keyboard.c (kbd_buffer_get_event):
7127 Don't reestablish signal handler; not needed with sigaction.
7128 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
7129 (UNBLOCK_INPUT_TO):
7130 Rework to avoid unnecessary accesses to volatile variables.
7131 (UNBLOCK_INPUT_TO): Now a function.
7132 (totally_unblock_input, unblock_input): New decls.
7133 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
7134 (init_data): Remove. Necessary stuff now done in init_signal.
7135 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
7136 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
7137 (fatal_error_code): Remove; no longer needed.
7138 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
7139 it doesn't always backtrace. All uses changed. No need to reset
7140 signal to default, since sigaction and/or die does that for us now.
7141 Use emacs_raise (FOO), not kill (getpid (), FOO).
7142 (main): Check more-accurately whether we're dumping.
7143 Move fatal-error setup to sysdep.c
7144 * floatfns.c: Do not include "syssignal.h"; no longer needed.
7145 * gtkutil.c (xg_get_file_name, xg_get_font):
7146 Remove no-longer-needed signal-mask manipulation.
7147 * keyboard.c, process.c (POLL_FOR_INPUT):
7148 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
7149 * keyboard.c (read_avail_input): Remove.
7150 All uses replaced by gobble_input.
7151 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
7152 (kbd_buffer_store_event_hold, gobble_input):
7153 (record_asynch_buffer_change) [USABLE_SIGIO]:
7154 (store_user_signal_events):
7155 No need to mess with signal mask.
7156 (gobble_input): If blocking input and there are terminals, simply
7157 set pending_signals to 1 and return. All hooks changed to not
7158 worry about whether input is blocked.
7159 (process_pending_signals): Clear pending_signals before processing
7160 them, in case a signal comes in while we're processing.
7161 By convention callers now test pending_signals before calling us.
7162 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
7163 New functions, to support changes to blockinput.h.
7164 (handle_input_available_signal): Now extern.
7165 (reinvoke_input_signal): Remove. All uses replaced by
7166 handle_async_input.
7167 (quit_count): Now volatile, since a signal handler uses it.
7168 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
7169 All callers changed. Block SIGINT only if not already blocked.
7170 Clear sigmask reliably, even if Fsignal returns, which it can.
7171 Omit unnecessary accesses to volatile var.
7172 (quit_throw_to_read_char): No need to restore sigmask.
7173 * keyboard.c (gobble_input, handle_user_signal):
7174 * process.c (wait_reading_process_output):
7175 Call signal-handling code rather than killing ourselves.
7176 * lisp.h: Include <float.h>, for...
7177 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
7178 (pending_signals): Now volatile.
7179 (syms_of_data): Now const if IEEE floating point.
7180 (handle_input_available_signal) [USABLE_SIGIO]:
7181 (terminate_due_to_signal, record_child_status_change): New decls.
7182 * process.c (create_process): Avoid disaster if memory is exhausted
7183 while we're processing a vfork, by tightening the critical section
7184 around the vfork.
7185 (send_process_frame, process_sent_to, handle_pipe_signal)
7186 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
7187 ignores SIGPIPE.
7188 (send_process): No need for setjmp/longjmp any more, since the
7189 SIGPIPE stuff is now gone. Instead, report an error if errno
7190 is EPIPE.
7191 (record_child_status_change): Now extern. PID and W are now args.
7192 Return void, not bool. All callers changed.
7193 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
7194 Remove. All uses removed. This bug should be fixed now in a
7195 different way.
7196 (wait_for_termination_1): Use waitpid rather than sigsuspend,
7197 and record the child status change directly. This avoids the
7198 need to futz with the signal mask.
7199 (process_fatal_action): Move here from emacs.c.
7200 (emacs_sigaction_flags): New function, containing
7201 much of what used to be in emacs_sigaction_init.
7202 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
7203 caught by emacs, to make races less likely.
7204 (deliver_process_signal): Rename from handle_on_main_thread.
7205 All uses changed.
7206 (BACKTRACE_LIMIT_MAX): Now at top level.
7207 (thread_backtrace_buffer, threadback_backtrace_pointers):
7208 New static vars.
7209 (deliver_thread_signal, deliver_fatal_thread_signal):
7210 New functions, for more-accurate delivery of thread-specific signals.
7211 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
7212 (deliver_arith_signal): Handle in this thread, not
7213 in the main thread, since it's triggered by this thread.
7214 (maybe_fatal_sig): New function.
7215 (init_signals): New arg DUMPING so that we can be more accurate
7216 about whether we're dumping. Caller changed.
7217 Treat thread-specific signals differently from process-general signals.
7218 Block all signals while handling fatal error; that's safer.
7219 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
7220 on IEEE hosts.
7221 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
7222 Ignore SIGPIPE unless batch.
7223 (emacs_backtrace): Output backtrace for the appropriate thread,
7224 which is not necessarily the main thread.
7225 * syssignal.h: Include <stdbool.h>.
7226 (emacs_raise): New macro.
7227 * xterm.c (x_connection_signal): Remove; no longer needed
7228 now that we use sigaction.
7229 (x_connection_closed): No need to mess with sigmask now.
7230 (x_initialize): No need to reset SIGPIPE handler here, since
7231 init_signals does this for us now.
7232
72332012-09-23 Jan Djärv <jan.h.d@swipnet.se>
7234
7235 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
7236 background rect may be larger (Bug#12245).
7237
72382012-09-23 Chong Yidong <cyd@gnu.org>
7239

72422012-09-22 Paul Eggert <eggert@cs.ucla.edu>
7243
7244 * .gdbinit: Just stop at fatal_error_backtrace.
7245 See Stefan Monnier's request in
7246 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
7247 Remove no-longer-used query of system type.
7248

7250
7251 * search.c (Freplace_match): Doc fix (Bug#12325).

72602012-09-22 Chong Yidong <cyd@gnu.org>
7261
7262 * dispextern.h (struct image_type): Add new slot, storing a type
7263 initialization function.
7264
7265 * image.c (define_image_type): Call the image initializer function
7266 if it is defined. Arguments and return value changed.
7267 (valid_image_p, make_image): Callers changed.
7268 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
7269 (gif_type, imagemagick_type, svg_type, gs_type):
7270 Add initialization functions.
7271 (Finit_image_library): Call lookup_image_type.
7272 (CHECK_LIB_AVAILABLE): Macro deleted.
7273 (lookup_image_type): Call define_image_type here, rather than via
7274 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
7275 (syms_of_image): Move define_image_type calls for xbm_type and
7276 pbm_type to lookup_image_type.
7277
72782012-09-22 Eli Zaretskii <eliz@gnu.org>
7279
7280 * keyboard.c (timer_check_2): Move calculation of 'timers' and
7281 'idle_timers' from here ...
7282 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
7283 lists, to avoid infloops when the timer does something stupid,
7284 like reinvoke itself with the same or smaller time-out.
7285 (Bug#12447)
7286
72872012-09-22 Martin Rudalics <rudalics@gmx.at>
7288
7289 * window.c (Fsplit_window_internal): Handle only Qt value of
7290 Vwindow_combination_limit separately.
7291 (Qtemp_buffer_resize): New symbol.
7292 (Vwindow_combination_limit): New default value.
7293 Rewrite doc-string.
7294

7296
7297 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
7298 the new overlay string. (Bug#10159)
7299
73002012-09-22 Paul Eggert <eggert@cs.ucla.edu>
7301
7302 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
7303 or that fprintf is async-signal-safe. POSIX doesn't require
7304 either assumption.
7305
73062012-09-22 Chong Yidong <cyd@gnu.org>
7307
7308 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
7309 (Bug#8207).
7310
73112012-09-22 Kenichi Handa <handa@gnu.org>
7312
7313 * composite.c (composition_reseat_it): Handle the case that a
7314 grapheme cluster is not covered by a single font (Bug#12352).
7315
73162012-09-21 Chong Yidong <cyd@gnu.org>
7317
7318 * image.c (define_image_type): Avoid adding duplicate types to
7319 image_types (Bug#12463). Suggested by Jörg Walter.
7320
73212012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7322
7323 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
7324 (print_load_command_name): Add case LC_DATA_IN_CODE.

73272012-09-21 Glenn Morris <rgm@gnu.org>
7328
7329 * eval.c (Frun_hook_with_args_until_success)
7330 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
7331
73322012-09-21 Andreas Schwab <schwab@linux-m68k.org>
7333
7334 * fileio.c (Ffile_selinux_context): Only call freecon when
7335 lgetfilecon succeeded.
7336 (Fset_file_selinux_context): Likewise. (Bug#12444)
7337
73382012-09-21 Eli Zaretskii <eliz@gnu.org>
7339
7340 * xdisp.c (try_window_reusing_current_matrix): Under bidi
7341 reordering, locate the cursor by calling set_cursor_from_row; if
7342 that fails, clear the desired glyph matrix before returning a
7343 failure indication to the caller. Fixes leaving garbled display
7344 when fast scrolling with a down-key. (Bug#12403)
7345 (compute_stop_pos_backwards): Fix a typo that caused crashes while
7346 scrolling through multibyte text.
7347
73482012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
7349
7350 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
7351 calling mark_vectorlike since that's the one that marks the window.
7352 (mark_discard_killed_buffers): Mark the final cdr.
7353 * window.h (struct window): Move prev/next_buffers to the
7354 non-standard fields.
7355 * window.c (make_window): Initialize prev/next_buffers manually.
7356

7364 * w32term.c (w32_read_socket):
7365 * xterm.c (XTread_socket):
7366 Omit unused arg EXPECTED. All callers changed.
7367 (store_user_signal_events): Return void, not int, since callers no
7368 longer care about the return value. All uses changed.
7369
73702012-09-20 Juanma Barranquero <lekktu@gmail.com>
7371
7372 * w32gui.h (XParseGeometry): Do not declare.
7373
73742012-09-19 Paul Eggert <eggert@cs.ucla.edu>
7375
7376 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
7377 Ignore 'expected'. See Eli Zaretskii in
7378 <http://bugs.gnu.org/12471#8> (last line).
7379
7380 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
7381 (XParseGeometry): Now static. Substitute extremal values for
7382 values that are out of range.
7383
73842012-09-19 Jan Djärv <jan.h.d@swipnet.se>
7385
7386 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
7387
7388 * nsfns.m (XParseGeometry): Remove.
7389 (Fx_create_frame): Call x_set_offset to correctly interpret
7390 top_pos in geometry.
7391
7392 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
7393 (Fx_parse_geometry): If there is a space in string, call
7394 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
7395
73962012-09-17 Eli Zaretskii <eliz@gnu.org>
7397
7398 * search.c (scan_buffer): Use character positions in calls to
7399 region_cache_forward and region_cache_backward, not byte
7400 positions. (Bug#12196)
7401
7402 * w32term.c (w32_read_socket): Set pending_signals to 1, like
7403 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
7404
7405 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
7406 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
7407 emacs_blocked_malloc, now deleted.
7408
74092012-09-17 Paul Eggert <eggert@cs.ucla.edu>
7410
7411 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
7412 The workaround was for improving performance on Solaris 2.4, but
7413 is getting in the way now. Emacs will still work if someone is
7414 still running Solaris 2.4 in a museum somewhere; Sun dropped
7415 support for Solaris 2.4 in 2003.
7416 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
7417 * process.c (create_process) [HAVE_WORKING_VFORK]:
7418 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
7419 since Emacs no longer uses vfork on that platform.
7420
74212012-09-17 Glenn Morris <rgm@gnu.org>

74252012-09-16 Paul Eggert <eggert@cs.ucla.edu>
7426
7427 Remove configure's --without-sync-input option (Bug#12450).
7428 When auditing signal-handling in preparation for cleaning it up,
7429 I found that SYNC_INPUT has race conditions and would be a real
7430 pain to fix. Since it's an undocumented and deprecated
7431 configure-time option, now seems like a good time to remove it.
7432 Also see <http://bugs.gnu.org/11080#16>.
7433 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
7434 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
7435 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
7436 (malloc_hysteresis):
7437 (check_depth) [XMALLOC_OVERRUN_CHECK]:

7441 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
7442 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
7443 [!SYSTEM_MALLOC && !SYNC_INPUT]:
7444 Remove. All uses removed.
7445 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
7446 implementation, one that depends on whether the new macro
7447 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
7448 is defined.
7449 * atimer.c (run_timers, handle_alarm_signal):
7450 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
7451 (handle_async_input, process_pending_signals)
7452 (handle_input_available_signal, init_keyboard):
7453 * nsterm.m (ns_read_socket):

7455 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
7456 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
7457 (emacs_write):
7458 * xterm.c (XTread_socket):
7459 Assume SYNC_INPUT.
7460 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
7461 * eval.c (handling_signal): Remove. All uses removed.
7462 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
7463 All uses replaced with the SYNC_INPUT version.
7464 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
7465 Remove decls.
7466 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7467 Now static.
7468
7469 * font.c (Ffont_shape_gstring): Remove unused local.
7470
74712012-09-16 Glenn Morris <rgm@gnu.org>
7472
7473 * Makefile.in (clean): No longer run nextstep's clean.
7474
7475 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
7476 (ns_frag): Remove.
7477 (ns-app): Move here from ns.mk, and simplify.
7478 (clean): Simplify nextstep entry.
7479 * ns.mk: Remove file.
7480
74812012-09-17 Kenichi Handa <handa@gnu.org>
7482
7483 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
7484 not covert the last few charactes.
7485
74862012-09-16 Kenichi Handa <handa@gnu.org>
7487
7488 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
7489 here, but just check the validity of glyphs in the glyph-string.
7490
74912012-09-16 Martin Rudalics <rudalics@gmx.at>
7492
7493 * window.c (Fwindow_parameter, Fset_window_parameter):
7494 Accept any window as argument (Bug#12452).
7495
74962012-09-16 Jan Djärv <jan.h.d@swipnet.se>
7497
7498 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
7499 to ns_term_init to avoid memory leak.
7500
7501 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
7502 explicit retain/release.
7503 (ns_term_init): Only allow one display. Initialize outerpool and
7504 ns_*_types.
7505
75062012-09-15 Paul Eggert <eggert@cs.ucla.edu>
7507
7508 Port _setjmp fix to POSIXish hosts as well as Microsoft.
7509 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
7510 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
7511 the Microsoft problem in a different way, by altering ../nt/config.nt.
7512
75132012-09-15 Eli Zaretskii <eliz@gnu.org>
7514
7515 * w32xfns.c:

7525 * w32fns.c:
7526 * w32console.c:
7527 * w32.c:
7528 * w16select.c: Remove inclusion of setjmp.h, as it is now included
7529 by lisp.h. This completes removal of setjmp.h inclusion
7530 erroneously announced in the previous commit. (Bug#12446)
7531
7532 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
7533 more accurate.
7534
7535 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
7536 not defined as a macro. The latter happens on MS-Windows.
7537 (Bug#12446)
7538
75392012-09-15 Paul Eggert <eggert@cs.ucla.edu>
7540
7541 Port better to POSIX hosts lacking _setjmp (Bug#12446).
7542 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
7543 Some instances of '#include <setjmp.h>' removed, if the
7544 only reason for the instance was because "lisp.h" was included.
7545 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
7546 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
7547 and _longjmp with the new symbols. Emacs already uses _setjmp if
7548 available, so this change affects only POSIXish hosts that have
7549 sigsetjmp but not _setjmp, such as some versions of Solaris and
7550 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
7551 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
7552 (png_load_body) [HAVE_PNG]:
7553 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
7554 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
7555 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
7556 since PNG requires jmp_buf. This is the only exception to the
7557 general rule that we now use sys_setjmp and sys_longjmp.
7558 This exception is OK since this code does not change the signal
7559 mask or longjmp out of a signal handler.
7560
75612012-09-14 Paul Eggert <eggert@cs.ucla.edu>
7562
7563 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
7564 Include "syssignal.h", for 'main_thread'.
7565
75662012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
7567
7568 Avoid out-of-range marker position (Bug#12426).
7569 * insdel.c (replace_range, replace_range_2):
7570 Adjust markers before overlays, as suggested by comments.
7571 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
7572 Remove redundant check before calling offset_intervals.
7573
75742012-09-14 Martin Rudalics <rudalics@gmx.at>
7575

7580
7581 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
7582
75832012-09-13 Paul Eggert <eggert@cs.ucla.edu>
7584
7585 Use a more backwards-compatible timer format (Bug#12430).
7586 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
7587 vector element, not from the 4th, since PSECS is now at the end.
7588 (Fcurrent_idle_time): Doc fix.
7589
75902012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
7591
7592 Function to mark objects and remove killed buffers at once.
7593 * alloc.c (discard_killed_buffers): Rename to ...
7594 (mark_discard_killed buffers) ... new name. Add marking
7595 of remaining objects. Fix comment. Adjust users.
7596 (mark_object): Do not touch frame buffer lists here.
7597 * frame.c (delete_frame): Reset frame buffer lists here.
7598
75992012-09-13 Paul Eggert <eggert@cs.ucla.edu>
7600
7601 Better workaround for GNOME bug when --enable-gcc-warnings.
7602 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
7603 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
7604 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
7605
7606 Simplify SIGIO usage (Bug#12408).
7607 The code that dealt with SIGIO was crufty and confusing, e.g., it
7608 played tricks like "#undef SIGIO" but these tricks were not used
7609 consistently. Simplify mostly by not #undeffing standard symbols,
7610 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
7611 or not as we please) rather than "defined SIGIO" (standard symbol
7612 that we probably shouldn't #undef).
7613 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
7614 Modules that need it can include it.
7615 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
7616 * dispextern.h (ignore_sigio): New decl.
7617 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
7618 unconditionally, since it's now a no-op if !USABLE_SIGIO.
7619 * emacs.c (shut_down_emacs):
7620 * keyboard.c (kbd_buffer_store_event_hold):
7621 Use ignore_sigio rather than invoking 'signal' directly.
7622 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
7623 for FIONREAD.
7624 (FIONREAD, SIGIO): Do not #undef.
7625 (tty_read_avail_input): Use #error rather than a syntax error.
7626 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
7627 for I_PIPE, used by SETUP_SLAVE_PTY.
7628 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
7629 * sysdep.c (croak): Remove; no longer needed. This bit of
7630 temporary code, with Fred N. Fish's comment that it's temporary,
7631 has been in Emacs since at least 1992!
7632 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
7633 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
7634 * syssignal.h (croak): Remove decl.
7635 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
7636 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
7637 now that we're termios-only.
7638 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
7639 * term.c (dissociate_if_controlling_tty): Use #error rather than
7640 a run-time error.
7641
7642 Work around GCC and GNOME bugs when --enable-gcc-warnings.
7643 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
7644 to work around GNOME bug 683906.
7645 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
7646 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
7647 This works around GCC bug 54561.
7648
76492012-09-12 Paul Eggert <eggert@cs.ucla.edu>
7650
7651 More fixes for 'volatile' and setjmp/longjmp.
7652 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
7653 * image.c (struct png_load_context) [HAVE_PNG]: New type.
7654 (png_load_body) [HAVE_PNG]:
7655 (jpeg_load_body) [HAVE_JPEG]:
7656 New function, with most of the old parent function's body.
7657 (png_load) [HAVE_PNG]:
7658 (jpeg_load) [HAVE_JPEG]:
7659 Invoke the new function, to avoid longjmp munging our locals.
7660 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
7661 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
7662 longjmp is passed 2, as the C standard doesn't guarantee this.
7663 Instead, store the failure code into mgr->failure_code.
7664
76652012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7666
7667 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
7668 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
7669 (syms_of_keyboard): Remove support for unread-command-char.
7670
76712012-09-12 Eli Zaretskii <eliz@gnu.org>
7672
7673 * w32proc.c (sys_kill): If PID is our process ID and the signal is
7674 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
7675 violation. (Bug#12426)
7676
76772012-09-12 Paul Eggert <eggert@cs.ucla.edu>
7678
7679 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
7680
76812012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7682
7683 * eval.c: Add `inhibit-debugger'.
7684 (Qinhibit_debugger): New symbol.
7685 (call_debugger): Bind it instead of Qdebug_on_error.
7686 (maybe_call_debugger): Test Vinhibit_debugger.
7687 (syms_of_eval): Define inhibit-debugger.
7688 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
7689 (syms_of_xdisp): Remove inhibit-debug-on-message.
7690
76912012-09-11 Paul Eggert <eggert@cs.ucla.edu>
7692
7693 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
7694 If a nonvolatile local variable is written before a _longjmp to
7695 the frame containing the variable, and is read after the _longjmp,
7696 the value read is indeterminate. Some local variables of type
7697 'struct handler' and 'struct catchtag' are used in this way, so
7698 mark each of their slots as volatile if the slot can be set before
7699 _longjmp and read afterwards.
7700 * lisp.h (struct handler): var and chosen_clause are now volatile.
7701 (struct catchtag): val, next, and pdlcount are now volatile.
7702
7703 * bidi.c (bidi_push_it, bidi_pop_it):
7704 * fns.c (copy_hash_table):
7705 * image.c (define_image_type):
7706 * keyboard.c (kbd_buffer_store_event_hold):
7707 * process.c (Fprocess_send_eof):
7708 * xfaces.c (x_create_gc) [HAVE_NS]:
7709 * xgselect.c (xg_select):
7710 Prefer assignment to memcpy when either will do.
7711
7712 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
7713 Use pointer-to-a-pointer to simplify and avoid a NILP check each
7714 time an item is removed. No need to mark this function 'inline';
7715 the compiler knows better than we do.
7716
77172012-09-11 Jan Djärv <jan.h.d@swipnet.se>
7718
7719 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
7720 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
7721 to change_frame_size (Bug#12388).
7722 (windowDidResize:): Pass YES to updateFrameSize.
7723
7724 * nsterm.h: Add delay parameter to updateFrameSize.
7725
77262012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
7727
7728 Discard killed buffers from deleted window and frame objects.
7729 This reduces an amount of references to killed buffers and
7730 helps GC to reclaim them faster.
7731 * alloc.c (discard_killed_buffers): New function.
7732 (mark_object): Use it for deleted windows and frames.
7733 (mark_object): If symbol's value is set up for a killed buffer
7734 or deleted frame, restore its global binding.
7735 * data.c (swap_in_global_binding): Add GC notice.
7736 (swap_in_symval_forwarding): Use convenient set_blv_where.
7737 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
7738 * window.h: ... to here.
7739
77402012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
7741
7742 Convenient macro to check whether the buffer is live.
7743 * buffer.h (BUFFER_LIVE_P): New macro.
7744 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
7745 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
7746
77472012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7748
7749 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
7750 composition cases (Bug#12364).
7751
7752 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
7753 overhang of succeeding glyphs overlapping box cursor.
7754
7755 * w32term.c (x_draw_glyph_string): Likewise.
7756
77572012-09-11 Paul Eggert <eggert@cs.ucla.edu>
7758
7759 Simplify, document, and port floating-point (Bug#12381).
7760 The porting part of this patch fixes bugs on non-IEEE platforms
7761 with frexp, ldexp, logb.
7762 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
7763 Now static.
7764 * floatfns.c: Simplify discussion of functions that Emacs doesn't
7765 support, by removing commented-out code and briefly listing the
7766 C89 functions excluded. The commented-out stuff was confusing
7767 maintenance, e.g., we thought we needed cbrt but it was commented out.
7768 (logb): Remove decl; no longer needed.
7769 (isfinite): New macro, if not already supplied.
7770 (isnan): Don't replace any existing macro.
7771 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
7772 are present on all C89 platforms.
7773 (Ffrexp): Do not special-case zero, as frexp does the right thing
7774 for that case.
7775 (Flogb): Do not use logb, as it doesn't have the desired meaning
7776 on hosts that use non-base-2 floating point. Instead, stick with
7777 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
7778 frexp, to avoid getting an unspecified result.
7779
7780 * xdisp.c (Qinhibit_debug_on_message): Now static.
7781
77822012-09-10 Jan Djärv <jan.h.d@swipnet.se>
7783
7784 * nsterm.m (ns_update_begin): Set clip path to whole view by using
7785 NSBezierPath (Bug#12131).
7786
77872012-09-10 Chong Yidong <cyd@gnu.org>
7788
7789 * fns.c (Fdelq, Fdelete): Doc fix.
7790
77912012-09-10 Paul Eggert <eggert@cs.ucla.edu>
7792
7793 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
7794 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
7795
77962012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
7797
7798 * lisp.h (make_lisp_ptr): New macro to replace XSET.
7799 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
7800 Use it.
7801
78022012-09-09 Eli Zaretskii <eliz@gnu.org>
7803
7804 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
7805 left fringe if the window has a left margin. This avoids leaving
7806 traces of the cursor because its leftmost pixel is not drawn over.
7807
7808 * dispnew.c (update_window_line): When the left margin area of a
7809 screen line is updated, set the redraw_fringe_bitmaps_p flag of
7810 that screen line. (Bug#12277)
7811
78122012-09-09 Paul Eggert <eggert@cs.ucla.edu>
7813
7814 Assume C89 or later for math functions (Bug#12381).
7815 This simplifies the code, and makes it a bit smaller and faster,
7816 and (most important) makes it easier to clean up signal handling
7817 since we can stop worring about floating-point exceptions in
7818 library code. That was a problem before C89, but the problem
7819 went away many years ago on all practical Emacs targets.
7820 * data.c, image.c, lread.c, print.c:
7821 Don't include <math.h>; no longer needed.
7822 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
7823 might be autoconfigured, as that never happens.
7824 * data.c (fmod):
7825 * doprnt.c (DBL_MAX_10_EXP):
7826 * print.c (DBL_DIG):
7827 Remove. C89 or later always defines these.
7828 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
7829 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
7830 (arith_error, domain_error, domain_error2):
7831 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
7832 no longer needed -- we simply return what C returns. All uses removed.
7833 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
7834 the wrapped code.
7835 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
7836 Remove. All uses expanded, as these macros are no longer used
7837 more than once and are now more trouble than they're worth.
7838 (Ftan): Use tan, not sin / cos.
7839 (Flogb): Assume C89 frexp.
7840 (fmod_float): Assume C89 fmod.
7841 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
7842 (init_floatfns): Remove. All uses removed.
7843
78442012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7845
7846 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
7847 compositeToPoint for OSX < 10.6 (Bug#12390).
7848
78492012-09-08 Paul Eggert <eggert@cs.ucla.edu>
7850
7851 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
7852 This produces more-accurate results.
7853
78542012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7855
7856 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
7857 changes (Bug#12088).
7858
78592012-09-08 Chong Yidong <cyd@gnu.org>
7860
7861 * syntax.c (Fstring_to_syntax): Doc fix.
7862
78632012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7864
7865 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
7866 in the internal border.
7867 (x_set_window_size): Remove static variables and their usage.
7868 (ns_redraw_scroll_bars): Fix NSTRACE arg.
7869 (ns_after_update_window_line, ns_draw_fringe_bitmap):
7870 Remove fringe/internal border adjustment (Bug#11052).
7871 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
7872 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
7873 (ns_fix_rect_ibw): Remove.
7874 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
7875 (ns_dumpglyphs_box_or_relief): Ditto.
7876 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
7877 adjustment.
7878 (ns_dumpglyphs_image): Ditto.
7879 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
7880 border adjustment.
7881 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
7882 their usage. Add fringe_extended_p and its use as in other terms.
7883 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
7884 scroll bar was removed.
7885 (updateFrameSize): New function.
7886 (windowDidResize): Move code to updateFrameSize and call it.
7887
7888 * nsterm.h (EmacsView): Add updateFrameSize.
7889
78902012-09-07 Chong Yidong <cyd@gnu.org>
7891
7892 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).

7897
7898 More signal-handler cleanup (Bug#12327).
7899 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
7900 Problem introduced when merging patches. Noted by Eli Zaretskii in
7901 <http://bugs.gnu.org/12327#67>.
7902 * floatfns.c: Comment fix.
7903 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
7904 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
7905 and anyway the declaration is harmless even if SIGDANGER is not defined.
7906 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
7907 defined BROKEN_FIONREAD). systty.h formerly did this, but other
7908 source files not surprisingly expected syssignal.h to define, or
7909 not define, SIGIO, and it's cleaner to do it that way, for consistency.
7910 Include <sys/ioctl.h>, for FIONREAD.
7911 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
7912 This eliminates a problem whereby other files mysteriously had
7913 to include "syssignal.h" before including "systty.h" if they
7914 wanted to use "#ifdef SIGIO".
7915
79162012-09-07 Eli Zaretskii <eliz@gnu.org>
7917
7918 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
7919
7920 * w32.c (sigemptyset): Empty the set.
7921 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
7922
7923 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
7924
79252012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
7926
7927 * alloc.c (mark_buffer): Revert unsafe marking optimization.
7928 (mark_object): Likewise for frame objects.
7929
79302012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7931
7932 * syssignal.h (handle_on_main_thread): Always declare,
7933 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
7934 This ports to platforms without HAVE_PTHREAD.
7935
79362012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7937
7938 Signal-handler cleanup (Bug#12327).
7939 Emacs's signal handlers were written in the old 4.2BSD style with
7940 sigblock and sigmask and so forth, and this led to some
7941 inefficiencies and confusion. Rewrite these to use
7942 pthread_sigmask etc. without copying signal sets around. Also,
7943 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
7944 'signal', and instead use functions that do not attempt to take
7945 over the system name space. This patch causes Emacs's text
7946 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
7947 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
7948 Do not include <signal.h> or "syssignal.h", as these
7949 modules do not use signals.
7950 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
7951 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
7952 Do not include <signal.h>, as "syssignal.h" does that for us now.
7953 * atimer.c (sigmask_atimers): New function.
7954 (block_atimers, unblock_atimers): New functions,
7955 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
7956 All uses replaced.
7957 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
7958 no longer needed here.
7959 * emacs.c (main): Inspect existing signal handler with sigaction,
7960 so that there's no need to block and unblock SIGHUP.
7961 * sysdep.c (struct save_signal): New member 'action', replacing
7962 old member 'handler'.
7963 (save_signal_handlers, restore_signal_handlers):
7964 Use sigaction instead of 'signal' to save and restore.
7965 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
7966 New function. All users of 'signal' modified to use set_sighandler
7967 if they're writeonly, and to use sys_signal if they're read+write.
7968 (emacs_sigaction_init, forwarded_signal): New functions.
7969 (sys_signal): Remove. All uses replaced by calls to sigaction
7970 and emacs_sigaction_init, or by direct calls to 'signal'.
7971 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
7972 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
7973 all uses replaced by pthread_sigmask etc. calls.
7974 * syssignal.h: Include <signal.h>.
7975 (emacs_sigaction_init, forwarded_signal): New decls.
7976 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
7977 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
7978 (sigmask, sys_sigmask): Remove; no longer needed.
7979 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
7980 (sigblock, sigunblock, sigfree):
7981 (sigsetmask) [!defined sigsetmask]:
7982 Remove. All uses replaced by pthread_sigmask.
7983 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
7984 no longer need to be replaced, and its typical old uses
7985 are now done via emacs_sigaction_init and sigaction.
7986 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
7987 (sys_sigdel): Remove; unused.
7988 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
7989
79902012-09-06 Eli Zaretskii <eliz@gnu.org>
7991
7992 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
7993 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
7994
79952012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7996
7997 Explicitly mark buffer_defaults and buffer_local_symbols.
7998 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
7999 mark_local_symbols here.
8000 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
8001 since special buffers aren't marked here any more.
8002 (allocate_buffer): Chain new buffer with all_buffers here...
8003 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
8004 not here.
8005 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
8006 (syms_of_buffer): Remove staticpro of the above.
8007 (init_buffer_once): Set names for buffer_defaults and
8008 buffer_local_symbols.
8009
80102012-09-06 Paul Eggert <eggert@cs.ucla.edu>
8011
8012 Use bool for booleans in font-related modules.
8013 * font.c (font_intern_prop, font_style_to_value)
8014 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
8015 (generate_otf_features, font_check_otf_features, font_check_otf)
8016 (font_match_p, font_list_entities, font_at):

8018 (fontset_find_font, Fset_fontset_font)
8019 (face_suitable_for_char_p) [0]:
8020 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
8021 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
8022 (m17n_flt_initialized, ftfont_shape_by_flt):
8023 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
8024 * nsfont.m (nsfont_draw):
8025 * w32font.c (w32font_draw):
8026 * w32term.c (x_draw_glyphless_glyph_string_foreground):
8027 Use bool for booleans.
8028 * font.h: Adjust to above API changes.
8029 (struct font, struct font_driver, struct font_driver_list):
8030 Use bool for booleans.
8031 (struct font): Remove useless member encoding_type.
8032 All users removed.
8033 * fontset.c, xftfont.c: Omit unnecessary static decls.
8034
80352012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
8036
8037 * alloc.c (mark_object): Revert window marking code
8038 since it's unsafe for the Fset_window_configuration.
8039
80402012-09-05 Paul Eggert <eggert@cs.ucla.edu>
8041
8042 Fix race conditions with signal handlers and errno (Bug#12327).
8043 Be more systematic about preserving errno whenever a signal
8044 handler returns, even if it's not in the main thread. Do this by
8045 renaming signal handlers to distinguish between signal delivery
8046 and signal handling. All uses changed.
8047 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
8048 * data.c (deliver_arith_signal): Rename from arith_error.
8049 * dispnew.c (deliver_window_change_signal): Rename from
8050 window_change_signal.
8051 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
8052 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
8053 * keyboard.c (deliver_input_available_signal): Rename from
8054 input_available_signal.
8055 (deliver_user_signal): Rename from handle_user_signal.
8056 (deliver_interrupt_signal): Rename from interrupt_signal.
8057 * process.c (deliver_pipe_signal): Rename from send_process_trap.
8058 (deliver_child_signal): Rename from sigchld_handler.
8059 * atimer.c (handle_alarm_signal):
8060 * data.c (handle_arith_signal):
8061 * dispnew.c (handle_window_change_signal):
8062 * emacs.c (handle_fatal_signal, handle_danger_signal):
8063 * keyboard.c (handle_input_available_signal):
8064 * keyboard.c (handle_user_signal, handle_interrupt_signal):
8065 * process.c (handle_pipe_signal, handle_child_signal):
8066 New functions, with the actual signal-handling code taken from the
8067 original respective signal handlers, sans the sporadic attempts to
8068 preserve errno, since that's now done by handle_on_main_thread.
8069 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
8070 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
8071 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
8072 Move to sysdep.c.
8073 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
8074 Move initialization of main_thread to sysdep.c's init_signals.
8075 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
8076 our usage, and simplifies the mainline code.
8077 (record_child_status_change): New static function, as a helper
8078 for handle_child_signal, and with most of the old child handler's
8079 contents.
8080 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
8081 (handle_child_signal): Use the above.
8082 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
8083 Moved here from emacs.c.
8084 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
8085 code moved here from emacs.c's main function.
8086 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
8087 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
8088 This lets callers save and restore errno properly.
8089
80902012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
8091
8092 Remove redundant or unused things here and there.
8093 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
8094 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
8095 * editfns.c (Fcompare_buffer_substrings): Likewise.
8096 * frame.h (struct terminal, struct font_driver_list):
8097 Remove redundant declarations.
8098 * window.h (Qleft, Qright): Likewise.
8099
81002012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
8101
8102 Do not mark objects from deleted buffers, windows and frames.
8103 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
8104 (mark_object): Likewise for windows and frames.
8105
81062012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
8107
8108 * alloc.c (valid_lisp_object_p): Treat killed buffers,
8109 buffer_defaults and buffer_local_symbols as valid objects.
8110 Return special value to denote them.
8111
81122012-09-05 Paul Eggert <eggert@cs.ucla.edu>
8113
8114 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
8115 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
8116 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
8117 (file_name_absolute_p, Fsubstitute_in_file_name):
8118 (check_executable, check_writable, Ffile_accessible_directory_p)
8119 (Fset_file_selinux_context, Fdefault_file_modes)
8120 (Finsert_file_contents, choose_write_coding_system)
8121 (Fwrite_region, build_annotations, a_write, e_write)
8122 (Fdo_auto_save):
8123 * filelock.c (boot_time_initialized, get_boot_time)
8124 (get_boot_time_1, lock_file_1, within_one_second):
8125 * floatfns.c (in_float):
8126 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
8127 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
8128 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
8129 * lisp.h (struct Lisp_Hash_Table.cmpfn):
8130 * window.c (compare_window_configurations):
8131 Use bool for booleans.
8132 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
8133 (Fdefault_file_modes): Now mode_t, not int, for modes.
8134 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
8135 (internal_delete_file): Now returns void, not a (boolean) int,
8136 since nobody was looking at the return value.
8137 * lisp.h, window.h: Adjust to above API changes.
8138
8139 * xdisp.c (set_message): Simplify and reindent last change.
8140
81412012-09-05 Juanma Barranquero <lekktu@gmail.com>
8142
8143 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
8144
81452012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
8146
8147 * eval.c (call_debugger): Make the function non-static so that we
8148 can call it from set_message.
8149
8150 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
8151 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
8152
81532012-09-04 Paul Eggert <eggert@cs.ucla.edu>
8154
8155 Give more-useful info on a fatal error (Bug#12328).
8156 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
8157 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
8158 of doing the work ourselves.
8159 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
8160 do most of the work.
8161 (fatal_error_backtrace): New function, taken from the guts
8162 of the old fatal_error_signal, but with a new option to output
8163 a backtrace.
8164 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
8165 info about the signal than just its number.
8166 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
8167 * sysdep.c: Include <execinfo.h>
8168 (emacs_backtrace): New function, taken partly from the previous
8169 code of the 'die' function.
8170 (emacs_abort): Call fatal_error_backtrace rather than abort.
8171
81722012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
8173
8174 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
8175 eager (load-time) macro-expansion.
8176 * lisp.mk (lisp): Add macroexp.
8177
81782012-09-04 Paul Eggert <eggert@cs.ucla.edu>
8179
8180 Simplify redefinition of 'abort' (Bug#12316).
8181 Do not try to redefine the 'abort' function. Instead, redo
8182 the code so that it calls 'emacs_abort' rather than 'abort'.
8183 This removes the need for the NO_ABORT configure-time macro
8184 and makes it easier to change the abort code to do a backtrace.
8185 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
8186 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
8187 Remove; sysdep.c's emacs_abort now takes its place.
8188 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
8189 'abort' changed to use 'emacs_abort'.
8190 * msdos.c (dos_abort) [defined abort]: Remove; not used.
8191 (abort) [!defined abort]: Rename to ...
8192 (emacs_abort): ... new name.
8193 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
8194 the place of the old 'abort' in emacs.c.
8195 * w32.c, w32fns.c (abort): Do not #undef.
8196 * w32.c (emacs_abort): Rename from w32_abort.
8197
81982012-09-04 Eli Zaretskii <eliz@gnu.org>
8199
8200 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
8201 offsets[j].dv, since the y axis of the screen coordinates points
8202 down, while the y axis of the font definition coordinates points
8203 up. This fixes display of Arabic diacritics such as KASRA and
8204 KASRATAN. (Bug#11860)
8205
82062012-09-04 Paul Eggert <eggert@cs.ucla.edu>
8207
8208 Be more systematic about _setjmp vs setjmp.
8209 * alloc.c (test_setjmp, mark_stack):
8210 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
8211 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
8212 (png_load, my_error_exit, jpeg_load):
8213 * process.c (send_process_trap, send_process):
8214 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
8215 The underscored versions are up to 30x faster on some hosts.
8216 Formerly, the code used setjmp+longjmp sometimes and
8217 _setjmp+_longjmp at other times, with no particular reason to
8218 prefer setjmp+longjmp.
8219
82202012-09-03 Paul Eggert <eggert@cs.ucla.edu>
8221
8222 Fix minor problem found by static checking.
8223 * buffer.c (Fdelete_all_overlays): Return nil.
8224
82252012-09-03 Martin Rudalics <rudalics@gmx.at>
8226
8227 * buffer.c (Fdelete_all_overlays): New function.
8228
82292012-09-03 Chong Yidong <cyd@gnu.org>
8230
8231 * gtkutil.c: Add extern decl for Qxft.
8232
82332012-09-02 Paul Eggert <eggert@cs.ucla.edu>
8234
8235 * emacs.c, eval.c: Use bool for boolean.
8236 * emacs.c (initialized, inhibit_window_system, running_asynch_code):

8242 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
8243 (maybe_call_debugger, Fbacktrace):
8244 * process.c (read_process_output, exec_sentinel):
8245 Use bool for booleans.
8246 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
8247 All callers changed.
8248 * eval.c (interactive_p): Omit always-true boolean argument
8249 EXCLUDE_SUBRS_P. All callers changed.
8250 * dispextern.h, lisp.h: Reflect above API changes.
8251 * firstfile.c (dummy): Use the address of 'main', whose signature
8252 won't change, instead of the address of 'initialize', whose
8253 signature just changed from int to bool.
8254 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
8255 * msdos.c (fatal_error_in_progress): ... from here.
8256 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
8257 of incrementing it.
8258 (redisplay_internal, unwind_redisplay): Simply clear
8259 REDISPLAYING_P when unwinding, instead of saving its previous,
8260 always-false value and then restoring it.
8261
8262 Clean up some extern decls.
8263 Mostly, this hoists extern decls out of .c files and into .h files.
8264 That way, we're more likely to catch errors if the interfaces change.
8265 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
8266 declare xg_mark_data.
8267 * dispextern.h (x_frame_parm_handlers):
8268 * font.h (Qxft):
8269 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

8274 * doc.c (Qclosure):
8275 * eval.c (Qlexical_binding):
8276 * fns.c (time) [!HAVE_UNISTD_H]:
8277 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
8278 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):

8285 * xfont.c (x_clear_errors):
8286 * xterm.c (x_frame_parm_handlers):
8287 Remove now-redundant extern decls.
8288 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
8289 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
8290 Now static.
8291 * xfaces.c: Remove unnecessary static decls.
8292 * xterm.c (updating_frame): Remove decl of nonexistent object.
8293
8294 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
8295 when building globals.h, as the objects that are not built on
8296 this host are not needed to compile C files on this host.
8297
82982012-09-02 Jan Djärv <jan.h.d@swipnet.se>
8299
8300 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
8301
8302 * frame.h: Add missing prototype for x_wm_set_size_hint.

8327 (set_intervals_multibyte_1, set_intervals_multibyte):
8328 * keyboard.c (decode_timer):
8329 Use bool for boolean.
8330 * intervals.h, lisp.h, systime.h: Reflect above API changes.
8331 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
8332
83332012-09-02 Chong Yidong <cyd@gnu.org>
8334
8335 * keymap.c (push_key_description): Print M-TAB as C-M-i
8336 (Bug#11758).
8337
83382012-09-02 Juanma Barranquero <lekktu@gmail.com>
8339
8340 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

8347
83482012-09-01 Eli Zaretskii <eliz@gnu.org>
8349
8350 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
8351 more than one grapheme cluster passed to the shaper: compute the
8352 offset adjustment values separately for each cluster. (Bug#11860)
8353
8354 * image.c: Restore mistakenly removed inclusion of w32.h. Without
8355 it, GCC doesn't see prototypes of w32_delayed_load, and complains
8356 about implicit conversions from integer to pointer.
8357
83582012-09-01 Daniel Colascione <dancol@dancol.org>
8359
8360 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
8361 system used too early.

8446 * lisp.h (mark_ttys): Remove prototype.
8447 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call

8664 (valid_lisp_object_p): Likewise.
8665
86662012-08-27 Martin Rudalics <rudalics@gmx.at>
8667
8668 * window.c (Fset_window_configuration): Record any window's old
8669 buffer if it's replaced (see Bug#8789). If the new current

8672
86732012-08-27 Dmitry Antipov <dmantipov@yandex.ru>

86812012-08-26 Paul Eggert <eggert@cs.ucla.edu>
8682

8689 Now static, not extern.
8690 * data.c (Qinterval): Remove; unused.
8691 (syms_of_data): Do not define 'interval'.
8692 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):

8707 (map_sub_char_table):
8708 Use bool for boolean.

8710 always 0. All callers changed.
8711 * character.h, charset.h: Adjust to match previous changes.
8712 * character.h (char_printable_p): Remove decl of nonexistent function.
8713 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
8714 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
8715 are all boolean, so make them single-bit bitfields.
8716
8717 * lisp.h (ASET): Remove attempt to detect side effects.
8718 It was meant to be temporary and it often doesn't work,
8719 because when IDX has side effects the behavior of IDX==IDX
8720 is undefined. See Stefan Monnier in
8721 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.

8730
8731 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
8732 as that's faster and simpler than static storage. Don't bother
8733 with the g_main_context_query overhead if g_main_context_pending
8734 says no events are pending.
8735 (gfds, gfds_size): Remove these static vars.
8736 (xgselect_initialize): Remove; no longer needed.
8737 All uses and decls removed.
8738
8739 * emacs.c (fatal_error_signal_hook): Remove.

8765 (getenv_internal, sync_process_alive, call_process_exited):
8766 * lisp.h (USE_SAFE_ALLOCA):
8767 Use bool for booleans, instead of int.
8768 * lisp.h, process.h: Adjust prototypes to match above changes.
8769 * callint.c (Fcall_interactively): Don't assume the mark's
8770 offset fits in 'int'.
8771
87722012-08-24 Paul Eggert <eggert@cs.ucla.edu>
8773

8781 (mmap_enlarge, mmap_set_vars):
8782 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
8783 Use bool for booleans, instead of int.
8784 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
8785 since the 1-or-0 return value is always ignored anyway.
8786 (mmap_initialized_p):
8787 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
8788 * buffer.h, lisp.h: Adjust prototypes to match above changes.
8789
87902012-08-23 Paul Eggert <eggert@cs.ucla.edu>
8791
8792 * bidi.c: Use bool for boolean.
8793 This is a bit more readable, and makes the text segment of bidi.o
8794 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
8795 Presumably it's faster too.
8796 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
8797 Now bool.
8798 (bidi_cache_find_level_change, bidi_cache_iterator_state)
8799 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
8800 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
8801 (bidi_explicit_dir_char, bidi_level_of_next_char)
8802 (bidi_find_other_level_edge, bidi_move_to_visually_next):
8803 Use bool for booleans, instead of int.
8804 * dispextern.h (bidi_init_it, bidi_paragraph_init)
8805 (bidi_unshelve_cache): Adjust decls to match code.
8806
88072012-08-23 Martin Rudalics <rudalics@gmx.at>
8808
8809 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
8810 argument.
8811
88122012-08-23 Paul Eggert <eggert@cs.ucla.edu>
8813
8814 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
8815 * atimer.h: Include <stdbool.h>.
8816
88172012-08-22 Dan Nicolaescu <dann@gnu.org>
8818
8819 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
8820 compile time tests instead of run time tests on systems that do
8821 not use them.
8822 (FRAME_MAC_P): Remove leftover from deleted code.
8823 * frame.c (syms_of_frame): Remove leftover from deleted code.
8824
88252012-08-22 Jan Djärv <jan.h.d@swipnet.se>
8826
8827 * nsterm.m (insertText:): Don't clear modifiers if code is space.
8828
88292012-08-22 Paul Eggert <eggert@cs.ucla.edu>
8830
8831 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
8832 Otherwise, the compiler complains about (A?B:C) where B is void
8833 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
8834 (fontset_add): Return void, for FONTSET_ADD.
8835
88362012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8837
8838 * alloc.c: Use bool for booleans.
8839 (gc_in_progress, abort_on_gc)
8840 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8841 (dont_register_blocks) [GC_MALLOC_CHECK]:
8842 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
8843 (check_string_bytes, make_specified_string, memory_full)
8844 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
8845 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
8846 (mark_stack, valid_pointer_p, make_pure_string)
8847 (Fgarbage_collect, survives_gc_p, gc_sweep):
8848 Use bool for booleans, instead of int.
8849 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8850 Remove unused local.
8851 * alloc.c (PURE_POINTER_P):
8852 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
8853 * editfns.c (Fformat):
8854 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
8855 (Fdo_auto_save):
8856 * fns.c (sweep_weak_table):
8857 * lisp.h (suppress_checking, push_message, survives_gc_p)
8858 (make_pure_string, gc_in_progress, abort_on_gc):
8859 * lread.c (readchar, read1):
8860 * print.c (Fprin1_to_string):
8861 * xdisp.c (push_message):
8862 Use bool for booleans affected directly or indirectly by
8863 alloc.c's changes.
8864
8865 Make recently-introduced setters macros.
8866 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
8867 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
8868 (set_fontset_default, set_fontset_fallback): Rename from their
8869 upper-case counterparts, and make them functions rather than macros.
8870 This is more consistent with the other recently-introduced setters.
8871 These don't need to be inline, since they're local.
8872
88732012-08-21 Jan Djärv <jan.h.d@swipnet.se>
8874
8875 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
8876 the loop (Bug#12247).
8877
88782012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8879
8880 * lisp.h (vcopy): Use memcpy rather than our own loop.
8881 This fixes a performance regression introduced by the recent
8882 addition of vcopy. This means 'vcopy' will need to be modified
8883 for a copying collector, but that's OK. Also, tighten the
8884 checking in the assertion.
8885
88862012-08-21 Eli Zaretskii <eliz@gnu.org>
8887
8888 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
8889 components for RTL text (Bug#11860). Adjust X-OFFSET of each
8890 non-base glyph for the width of the base character, according to
8891 what x_draw_composite_glyph_string_foreground expects.
8892 Generate WADJUST value according to composition_gstring_width's
8893 expectations, to produce correct width of the composed character.
8894 Reverse the sign of the DU offset produced by ScriptPlace.
8895
88962012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8897
8898 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
8899
89002012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8901
8902 Avoid direct writes to contents member of struct Lisp_Vector.
8903 * lisp.h (vcopy): New function to copy data into vector.
8904 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
8905 * fns.c (Ffillarray): Use ASET.
8906 * keyboard.c (timer_check_2): Use AREF and ASET.
8907 (append_tool_bar_item, Frecent_keys): Use vcopy.
8908 * lread.c (read_vector): Use ASET.
8909 * msdos.c (Frecent_doskeys): Use vcopy.
8910 * xface.c (Finternal_copy_lisp_face): Use vcopy.
8911 (Finternal_merge_in_global_face): Use ASET and vcopy.
8912 * xfont.c (xfont_list_pattern): Likewise.
8913
89142012-08-21 Martin Rudalics <rudalics@gmx.at>
8915
8916 * window.c (Fwindow_point): For the selected window always return
8917 the position of its buffer's point.
8918 (Fset_window_point): For the selected window always go in its
8919 buffer to the specified position.
8920
89212012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8922
8923 Setter macros for fontsets.
8924 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
8925 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
8926 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
8927 Adjust users.
8928
89292012-08-20 Glenn Morris <rgm@gnu.org>
8930
8931 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
8932 Don't assume that `ln -f' works.
8933
89342012-08-20 Eli Zaretskii <eliz@gnu.org>
8935
8936 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
8937 and later about non-assignments with no effect. See discussion at
8938 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
8939 details.
8940
89412012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8942
8943 Inline setter functions for Lisp_Objects slots of struct specbinding.
8944 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
8945 Adjust users.
8946
89472012-08-20 Martin Rudalics <rudalics@gmx.at>
8948
8949 * window.c (select_window): Always make selected window's buffer
8950 current.
8951
89522012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8953
8954 Use AREF and ASET for docstrings of category tables.
8955 * category.h (CATEGORY_DOCSTRING): Use AREF.
8956 (SET_CATEGORY_DOCSTRING): Use ASET.
8957 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
8958
89592012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8960
8961 Inline setter functions for hash table members.
8962 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
8963 (set_hash_hash, set_hash_index): Rename with _slot suffix.
8964 (set_hash_key_and_value, set_hash_index, set_hash_next)
8965 (set_hash_hash): New functions.
8966 * charset.c, fns.c: Adjust users.
8967
89682012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8969
8970 Inline getter and setter functions for per-buffer values.
8971 * buffer.h (per_buffer_default, set_per_buffer_default)
8972 (per_buffer_value, set_per_buffer_value): New functions.
8973 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
8974 * buffer.c, data.c: Adjust users.
8975
89762012-08-20 Juanma Barranquero <lekktu@gmail.com>
8977
8978 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
8979
89802012-08-19 Paul Eggert <eggert@cs.ucla.edu>
8981
8982 Rely on <config.h> + <unistd.h> to declare 'environ',
8983 as gnulib does this if the system doesn't.
8984 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
8985 Remove declaration. MS-Windows declares it on stdlib.h which is
8986 included by conf_post.h.
8987 * emacs.c (environ) [DOUG_LEA_MALLOC]:
8988 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
8989 * vm-limit.c: Include <unistd.h>, for 'environ'.
8990
8991 * unexaix.c, unexcoff.c: Include "mem-limits.h".
8992 (start_of_data): Remove decl; mem-limits.h provides it.
8993
8994 * xdisp.c (handle_invisible_prop): Make it a bit faster
8995 and avoid a gcc -Wmaybe-uninitialized diagnostic.
8996
89972012-08-19 Chong Yidong <cyd@gnu.org>
8998
8999 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
9000 ends (Bug#3874).
9001
90022012-08-19 Andreas Schwab <schwab@linux-m68k.org>
9003
9004 * .gdbinit: Use call instead of set when calling a function in the
9005 inferior.
9006
9007 * data.c (set_internal): Don't use set_blv_found.
9008 (Fkill_local_variable): Likewise.
9009
90102012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
9011
9012 * nsfont.m (ns_ascii_average_width): Ensure the string
9013 ascii_printable is initialized with a null-terminated character
9014 array. Otherwise, it can contain undesired extra characters.
9015
90162012-08-18 Paul Eggert <eggert@cs.ucla.edu>
9017
9018 port new setting code to Sun C 5.8 2005/10/13
9019 * chartab.c, lisp.h (char_table_set, char_table_set_range):
9020 Return void, not Lisp_Object. Otherwise, the compiler
9021 complains about (A?B:C) where B is void and C is Lisp_Object
9022 when compiling CHAR_TABLE_SET, due to the recent change to
9023 the API of sub_char_table_set_contents.
9024
90252012-08-18 Chong Yidong <cyd@gnu.org>
9026
9027 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
9028 for the string case (Bug#3874).
9029
90302012-08-18 Paul Eggert <eggert@cs.ucla.edu>
9031
9032 * buffer.h (BSET): Remove (Bug#12215).

9145 Define to EXTERN_INLINE, so that the corresponding functions
9146 are compiled into code.
9147 (fset_buffer_predicate, fset_minibuffer_window): New setter functions.
9148
9149 A few more naming-convention fixes for getters and setters.

9183 The old version was confusing because it used the same name
9184 'parent' for two different things.

9860 value of EMACSLOADPATH, as it is no longer needed.
9861 (check_windows_init_file): Now external, not static.
9862 Use Vload_path as is, without adding anything, as this function is now

9866
9867 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

9910 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
9911 Remove unnecessary pointer casts.
9912 * alloc.c (record_xmalloc): New function.
9913 * lisp.h (record_xmalloc): New decl.
9914 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts

9917 * print.c (print_string, print_error_message): Avoid length recalc.
9918
9919 Improve fix for macroexp crash with debugging (Bug#12118).
9920 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
9921 ARRAY_MARK_FLAG when checking subscripts, because ASET is
9922 not supposed to be invoked from the garbage collector.
9923 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
9924 (gc_aset): New function, which is like ASET but can be
9925 used in the garbage collector.

9954 with addition of handling of symlinks and support for 'lstat'.
9955 If possible, get file's attributes and security information by
9956 handle, not by name. Produce S_IFLNK bit for symlinks, when
9957 called from 'lstat'.
9958 (stat, lstat): New functions, call 'stat_worker'.
9959 (symlink, readlink, careadlinkat): Rewritten to create and resolve
9960 symlinks when the underlying filesystem supports them.
9961

9963
9964 Fix macroexp crash on Windows with debugging (Bug#12118).
9965 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
9966 checking subscripts; problem introduced with the recent
9967 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
9968 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
9969 since it's used in non-static inline functions now.
9970
9971 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
9972 Don't assume buffer size fits in 'int'. Remove unused local.

10409 (w32_kbd_patch_key, key_event): Use the codepage returned by
10410 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
10411 (key_event): use uChar.UnicodeChar only if
10412 w32_console_unicode_input is non-zero.
10413

10423
104242012-07-27 Paul Eggert <eggert@cs.ucla.edu>
10425
10426 Adjust GDB to reflect pvec_type changes (Bug#12036).
10427 * .gdbinit (xvectype, xpr, xbacktrace): Adjust to reflect the
10428 2012-07-04 changes to pseudovector representation.
10429 Problem reported by Eli Zaretskii in <http://bugs.gnu.org/12036#30>.
10430

10440 list.
10441
10442 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
10443 enumeration constants, as PURE and HEAP are too general, and clash
10444 with other headers and sources, such as gmalloc.c and the
10445 MS-Windows system headers. All users changed.
10446
104472012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10448
10449 Revert last save_excursion_save and save_excursion_restore changes.

10454
10455 Fix recently-introduced typos in Windows port.

10458 * w32fns.c (syms_of_w32fns): Add missing parenthesis.
10459
104602012-07-27 Paul Eggert <eggert@cs.ucla.edu>
10461
10462 Improve GDB symbol export (Bug#12036).
10463 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
10464 arms of an 'if', not using conditional expressions; otherwise GDB
10465 complains about the types in the unevaluated arm when the argument
10466 is an integer literal.
10467 (xgetint): Simplify expression.
10468 * alloc.c (gdb_make_enums_visible): New constant. This ports to
10469 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
10470 Zaretskii in <http://bugs.gnu.org/12036#13>.
10471 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
10472 needed now that we have gdb_make_enums_visible.
10473 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
10474 (enum enum_USE_LSB_TAG):
10475 New enum types, packaging up enums that need to be exported to GDB.
10476
104772012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10478
10479 Utility function to make a list from specified amount of objects.
10480 * lisp.h (enum constype): New datatype.
10481 (listn): New prototype.
10482 * alloc.c (listn): New function.
10483 (Fmemory_use_count, syms_of_alloc): Use it.
10484 * buffer.c (syms_of_buffer): Likewise.
10485 * callint.c (syms_of_callint): Likewise.
10486 * charset.c (define_charset_internal): Likewise.

10499 * lisp.h (struct Lisp_Excursion): New data type.
10500 (PVEC_EXCURSION): New pseudovector type.
10501 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
10502 to deal with it. Adjust comments.
10503 (init_marker, attach_marker): New prototype.
10504 (unchain_marker): Adjust prototype.
10505 * marker.c (attach_marker): Change to global.
10506 (init_marker): New function.
10507 * alloc.c (Fmake_marker, build_marker): Use it.
10508 (build_marker): More easserts.
10509 (mark_object): Handle struct Lisp_Excursion.
10510 * editfns.c (save_excursion_save, save_excursion_restore):
10511 Reimplement to use struct Lisp_Excursion. Add comments.
10512
105132012-07-26 Paul Eggert <eggert@cs.ucla.edu>
10514
10515 Fix export of symbols to GDB (Bug#12036).
10516 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
10517 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
10518 emacs.c, as this is a more-suitable home. Had this been done earlier
10519 the fix for 12036 would have avoided some of the problems noted in
10520 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
10521 would have been more obvious.
10522 * emacs.c: Do not include <verify.h>; no longer needed.
10523 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)

10530 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
10531 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
10532 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
10533 not be usable in #if. This simplifies things.
10534
105352012-07-26 Juanma Barranquero <lekktu@gmail.com>
10536
10537 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

105392012-07-26 Paul Eggert <eggert@cs.ucla.edu>
10540
10541 Simplify export of symbols to GDB (Bug#12036).
10542 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
10543 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
10544 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
10545 Adjust to changes in lisp.h and emacs.c, by using
10546 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
10547 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
10548 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
10549 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
10550 instead of gdb_valbits.
10551 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
10552 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
10553 instead of gdb_array_mark_flag.
10554 (xboolvector): Get size from $->size, not $->header.size.
10555 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
10556 (xreload, hook-run, hookpost-run): Remove.
10557 * emacs.c: Include <verify.h>.
10558 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
10559 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
10560 Remove.
10561 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
10562 (gdb_USE_LSB_TAG): New enum constants.
10563 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
10564 Also define these as enum constants, so they're visible to GDB.
10565 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
10566 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
10567 as constants, so they're visible to GDB.
10568 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
10569 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
10570 Now enum constants, not macros, so they're visible to GDB.
10571 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
10572 more convenient now. All uses changed.
10573 (VALMASK) [USE_LSB_TAG]: Also define in this case.
10574 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
10575
105762012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
10577
10578 Explicitly free restriction data that are not needed anymore.
10579 * editfns.c (save_restriction_restore): Free restriction data.
10580

10582
10583 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
10584 add argument, tune behavior, and adjust all callers.
10585
105862012-07-25 Paul Eggert <eggert@cs.ucla.edu>
10587
10588 Use typedef for EMACS_INT, EMACS_UINT.
10589 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
10590 than macros. This simplifies debugging in the usual case, since
10591 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
10592 and it allows expressions involving EMACS_INT casts.
10593 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
10594
105952012-07-25 Jan Djärv <jan.h.d@swipnet.se>
10596
10597 * nsterm.m (ns_read_socket): Return early if there is a modal
10598 window (Bug#12043).
10599
106002012-07-25 Martin Rudalics <rudalics@gmx.at>
10601
10602 * frame.c (Fredirect_frame_focus): In doc-string don't mention

10606
10607 Adjust buffer text indirection counters at the end of Fkill_buffer.
10608 * buffer.c (Fkill_buffer): Adjust indirection counters when the
10609 buffer is definitely dead. This should really fix an issue reported
10610 by Christoph Scholtes again. (Bug#12007).
10611 (init_buffer_once): Initialize indirection counters of
10612 buffer_defaults and buffer_local_symbols (for sanity and safety).

10629 or invalid. (Bug#12025)
10630
10631 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
10632 it signals an error when a tooltip frame is being created.
10633
106342012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
10635
10636 Cleanup miscellaneous objects allocation and initialization.
10637 * alloc.c (allocate_misc): Change to static. Add argument to
10638 specify the subtype. Adjust comment and users.
10639 (build_overlay): New function.
10640 * buffer.c (copy_overlays, Fmake_overlay): Use it.
10641 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.

10647 Swap buffer text indirection counters in Fbuffer_swap_text.
10648 * buffer.c (Fbuffer_swap_text): Swap indirections too.
10649 This avoids crash reported by Christoph Scholtes at
10650 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
10651
106522012-07-22 Jan Djärv <jan.h.d@swipnet.se>
10653
10654 * nsmenu.m (Popdown_data): New struct.

10678
10679 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
10680 as it's limited by the amount of memory, not by INT_MAX.

10683
10684 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'

10687 for the reasons.
10688
10689 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning
10690 info.dwItemData. Fixes crashes on 64-bit Windows.
10691 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.

10712 (Fkill_buffer): Adjust indirection counters as needed, don't walk
10713 through buffer list if indirection counter is 0.
10714
107152012-07-20 Dmitry Antipov <dmantipov@yandex.ru>
10716

11410 EMACS_TIME simplification (Bug#11875).
11411 This replaces macros (which typically do not work in GDB)

11413 The functional style also makes code easier to read and maintain.
11414 * systime.h: Include <sys/time.h> on all hosts, not just if
11415 WINDOWSNT, since 'struct timeval' is needed in general.

11428 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
11429 not functions. All uses rewritten to use the following, respectively:
11430 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
11431 (add_emacs_time, sub_emacs_time): New functions.
11432 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

11449 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
11450 (menu_separator_name_p):
11451 * nsmenu.m (ns_update_menubar):
11452 Prefer memcmp to strncmp when either will do.
11453 * nsterm.m: Include <ftoastr.h>.
11454 (ns_get_color):
11455 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
11456 Prefer snprintf to strncpy.
11457 * nsterm.m (ns_term_init):
11458 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
11459 * nsterm.m (ns_term_init):
11460 Avoid the need for strncpy, by using build_string or
11461 make_unibyte_string directly. Use dtoastr, not snprintf.
11462 * process.c (Fmake_network_process): Diagnose service names that
11463 are too long, rather than silently truncating them or creating
11464 non-null-terminated names.
11465 (Fnetwork_interface_info): Likewise, for interface names.
11466 * sysdep.c (system_process_attributes) [GNU_LINUX]:
11467 Prefer sprintf to strncat.

11475
114762012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

11497 provides a better opportunity to optimize away calls to strlen when
11498 the function is called with compile-time constant argument.
11499 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
11500 argument, adjust users accordingly. Use build_pure_c_string where
11501 appropriate.
11502 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
11503 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
11504 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.

11527 Move PENDING_OUTPUT_COUNT definition to configure.
11528
11529 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
11530 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
11531 * s/gnu.h (DATA_START): Move definitions to configure.
11532
11533 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
11534 We include usg5-4-common.h, which defines them both.
11535
11536 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
11537 O_RDONLY already includes it).
11538
11539 Stop ns builds setting the EMACSLOADPATH environment variable.
11540 * nsterm.m (ns_load_path): Rename from ns_init_paths.
11541 Now it does not set EMACSLOADPATH, just returns the load-path string.
11542 * nsterm.h: Update accordingly.
11543 * lread.c [HAVE_NS]: Include nsterm.h.
11544 (init_lread) [HAVE_NS]: Use ns_load_path.

11546
115472012-07-09 Glenn Morris <rgm@gnu.org>
11548
11549 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
11550 since the included bsd-common.h does so.
11551
11552 Stop ns builds setting the EMACSPATH environment variable.
11553 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
11554 (ns_init_paths): Do not set EMACSPATH.
11555 * nsterm.h (ns_exec_path): Add it.
11556 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
11557 Use ns_exec_path.
11558
11559 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
11560
115612012-07-09 Paul Eggert <eggert@cs.ucla.edu>
11562
11563 * process.c (wait_reading_process_output): 'waitchannels' was unset
11564 when read_kbd || !NILP (wait_for_cell); fix this.
11565
11566 Add GCC-style 'const' attribute to functions that can use it.
11567 * character.h (char_resolve_modifier_mask):
11568 * keyboard.h (make_ctrl_char):
11569 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
11570 (init_character_once, next_almost_prime, init_fns, init_image)
11571 (flush_pending_output, init_sound):
11572 * mem-limits.h (start_of_data):
11573 * menu.h (finish_menu_items):
11574 Add ATTRIBUTE_CONST.
11575 * emacs.c (DEFINE_DUMMY_FUNCTION):
11576 Declare the dummy function with ATTRIBUTE_CONST.
11577 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
11578 Add decls with ATTRIBUTE_CONST.
11579
11580 Minor improvements to make_formatted_string.
11581 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
11582 where int is good enough, as vsprintf returns an int.
11583 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
11584
115852012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
11586
11587 Use make_formatted_string to avoid double length calculation.
11588 * lisp.h (make_formatted_string): New prototype.
11589 * alloc.c (make_formatted_string): New function.
11590 * buffer.c (Fgenerate_new_buffer_name): Use it.

11604
11605 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
11606 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
11607 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.
11608 * nsterm.h (ns_etc_directory): Add it.
11609 * callproc.c [HAVE_NS]: Include nsterm.h.
11610 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
11611
116122012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
11613
11614 Move marker debugging code under MARKER_DEBUG.
11615 * marker.c (MARKER_DEBUG): Move marker debugging code under
11616 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
11617 for bootstrap with --enable-checking (~3x slowdown reported
11618 by Juanma Barranquero <lekktu@gmail.com>).
11619 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
11620
116212012-07-08 Paul Eggert <eggert@cs.ucla.edu>
11622
11623 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
11624 See <http://bugs.gnu.org/11825#29>.
11625
116262012-07-08 Eli Zaretskii <eliz@gnu.org>
11627
11628 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
11629 has no font, use the frame's font. (Bug#11813)
11630 (display_line): Add commentary about displaying truncation glyphs
11631 on GUI frames.
11632 (produce_special_glyphs): Move here from term.c.
11633
11634 * term.c (produce_special_glyphs): Move to xdisp.c.
11635
11636 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
11637 section.
11638
116392012-07-07 Andreas Schwab <schwab@linux-m68k.org>
11640
11641 * xdisp.c (display_line): Avoid warning about implicit declaration
11642 of FRAME_FONT.
11643
11644 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
11645
11646 * lisp.h: Remove empty conditional.
11647
116482012-07-07 Paul Eggert <eggert@cs.ucla.edu>
11649
11650 * lread.c (load_path_check): Now static.
11651
11652 Fix some minor --with-ns problems found by static checking.
11653 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
11654 (x_set_font) [!HAVE_X_WINDOWS]:
11655 * image.c (xpm_load_image) [HAVE_NS]:
11656 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
11657 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
11658 Remove unused local.
11659 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
11660 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
11661 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
11662 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
11663 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
11664 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
11665 Fix pointer signedness problem.
11666 * xfaces.c (FRAME_X_FONT_TABLE):
11667 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
11668
116692012-07-07 Glenn Morris <rgm@gnu.org>
11670
11671 * lread.c (load_path_check): New function, split from init_lread.
11672 (init_lread): Reorganize. Motivation:
11673 If EMACSLOADPATH is set, check/warn about that rather than the
11674 defaults, which we are not going to use. Hence we can remove
11675 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
11676 Don't warn if site-lisp directories are missing.
11677 If not installed, start from a blank load-path, since
11678 PATH_LOADSEARCH refers to the eventual installation directories.
11679
116802012-07-07 Eli Zaretskii <eliz@gnu.org>
11681
11682 Support truncation and continuation glyphs on GUI frames, when
11683 fringes are disabled. (Bug#11832)
11684 * xdisp.c (init_iterator): Get dimensions of truncation and
11685 continuation glyphs even if on GUI frames.
11686 Adjust it->last_visible_x on GUI frames when the left or right fringes,
11687 or both, are absent.
11688 (start_display, move_it_in_display_line_to): Handle the case of a
11689 GUI frame without a fringe to display continuation or truncation
11690 glyphs.
11691 (insert_left_trunc_glyphs): Support GUI frames: make sure
11692 truncation glyphs overwrite enough glyphs from the current line to
11693 have sufficient space in pixels.
11694 (display_line): Support truncation and continuation glyphs on GUI
11695 frames. If some spare pixels are left on the line after inserting
11696 the truncation glyphs, fill that space with a stretch glyph of a
11697 suitably computed width.
11698
11699 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
11700 produce_glyphs, to support GUI sessions.
11701

11703
11704 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
11705
11706 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
11707
11708 Do not require float-time's arg to fit in time_t (Bug#11825).
11709 This works better on hosts where time_t is unsigned, and where
11710 float-time is applied to the (negative) difference between two times.
11711 * editfns.c (decode_time_components): Last arg is now double *,
11712 not int *, and means to store all the result as a double, without
11713 worrying about whether the seconds part fits in time_t.
11714 All callers changed.
11715 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
11716 All callers changed.
11717 (Ffloat_time): Do not fail merely because the specified time falls
11718 outside of time_t range.
11719
117202012-07-07 Glenn Morris <rgm@gnu.org>
11721
11722 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
11723 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
11724 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
11725
117262012-07-07 Juanma Barranquero <lekktu@gmail.com>

11728 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
11729 Update dependencies.
11730
11731 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
11732
117332012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11734
11735 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
11736 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
11737 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
11738 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
11739 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
11740 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
11741
11742 * xfont.c (compare_font_names): Redo to omit the need for casts.
11743
117442012-07-06 Andreas Schwab <schwab@linux-m68k.org>
11745
11746 * xfns.c (Fx_change_window_property): Doc fix.

11748
11749 * w32fns.c (Fx_window_property): Accept the same arguments as the
11750 X Windows version. Doc fix.
11751 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
11752
117532012-07-06 Juanma Barranquero <lekktu@gmail.com>
11754 Eli Zaretskii <eliz@gnu.org>
11755
11756 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
11757 Windows-specific code from nt/config.nt moved here.
11758 Obsolete settings removed.
11759
117602012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11761
11762 * process.c: Avoid unnecessary calls to gettime.
11763 (wait_reading_process_output): Don't get the time of day
11764 when gobbling data immediately and not waiting, as there's no need
11765 for it in that case. This removes a FIXME.
11766
117672012-07-06 Jan Djärv <jan.h.d@swipnet.se>
11768
11769 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
11770 is defined (Bug#11768).
11771
117722012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11773
11774 Fix marker debugging code.
11775 * marker.c (byte_char_debug_check): Do not perform the check
11776 if buffer is not multibyte.
11777 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
11778 Call byte_char_debug_check with correct arguments.
11779
117802012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11781
11782 Compile marker debugging code only if ENABLE_CHECKING is defined.
11783 * marker.c (byte_char_debug_check, count_markers):
11784 Use only if ENABLE_CHECKING is defined.
11785 (byte_debug_flag): Remove.
11786 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
11787 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
11788
117892012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11790
11791 Avoid code repetition in marker-related functions.
11792 * marker.c (attach_marker): New function.
11793 (Fset_marker, set_marker_restricted, set_marker_both)
11794 (set_marker_restricted_both): Use it.
11795 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
11796 Consistently rename charno to charpos.
11797 (marker_position): Add eassert.
11798 (marker_byte_position): Convert to eassert.
11799
118002012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11801
11802 Simplify list operations in unchain_overlay and unchain_marker.
11803 * buffer.c (unchain_overlay): Simplify. Add comment.
11804 * marker.c (unchain_marker): Simplify. Fix comments.
11805
118062012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11807

11810 * lisp.h (build_marker): New prototype.
11811 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
11812 * composite.c (autocmp_chars): Likewise.
11813 * editfns.c (buildmark): Remove.
11814 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
11815 (save_restriction_save): Use build_marker.
11816 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.

11824 (delete_all_overlays, Fdelete_overlay): Use it.
11825 * minibuf.c (get_minibuffer): Fix comment.

118272012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11828
11829 Port to OpenBSD 5.1 amd64.
11830 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
11831 This is needed for OpenBSD, and should be harmless on all BSD systems.
11832 Also, include <sys/sysctl.h>, as it should be available on all
11833 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
11834 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
11835 use p_pid member, not kp_proc.pid.
11836
118372012-07-06 Glenn Morris <rgm@gnu.org>
11838
11839 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.

11851 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
11852 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
11853 * xterm.c:
11854 Omit needless casts involving void * pointers and allocation.
11855 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
11856 as the former is more robust if P's type is changed.
11857 Prefer xzalloc to xmalloc + memset 0.
11858 Simplify malloc-or-realloc to realloc.
11859 Don't worry about xmalloc returning a null pointer.
11860 Prefer xstrdup to xmalloc + strcpy.
11861 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
11862 growing it.
11863 * keyboard.c (apply_modifiers_uncached): Prefer local array to
11864 alloca of a constant.
11865
118662012-07-05 Eli Zaretskii <eliz@gnu.org>
11867
11868 * xdisp.c (display_line): Fix horizontal pixel coordinates when
11869 hscroll is larger than the line width. Fixes long and futile
11870 looping inside extend_face_to_end_of_line (on a TTY) producing
11871 glyphs that are not needed and thrown away.
11872
118732012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
11874
11875 * marker.c (set_marker_restricted_both): Simplify by using
11876 clip_to_bounds.

11883
11884 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
11885 not defined (Bug#11768).
11886 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
11887 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
11888 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
11889 followed by gtk_box_set_homogeneous (Bug#11768).
11890 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
11891 (update_theme_scrollbar_width, xg_create_scroll_bar):
11892 Use gtk_scrollbar_new (Bug#11768).
11893 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
11894 (is_box_type): New function (Bug#11768).
11895 (xg_tool_item_stale_p): Call is_box_type.
11896 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
11897 with default display (Bug#11768).
11898
118992012-07-05 Eli Zaretskii <eliz@gnu.org>
11900
11901 * xdisp.c (window_hscroll_limited): New function.
11902 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
11903 coordinates when window's hscroll is set to insanely large
11904 values. (Bug#11857)
11905
119062012-07-05 Juanma Barranquero <lekktu@gmail.com>
11907
11908 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

11968
11969 * fileio.c (time_error_value): Check the right error number.
11970 Problem reported by Troels Nielsen in
11971 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

119732012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11974
11975 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
11976 This should be fixed in a better way; see Eli Zaretskii in
11977 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
11978 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
11979
11980 * fileio.c (time_error_value): Rename from special_mtime.
11981 The old name's problems were noted by Eli Zaretskii in
11982 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
11983
11984 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
11985 This variable's comment says Emacs needs at least one GDB-visible
11986 symbol of type enum pvec_type, to work around GDB problems.
11987 The symbol's value doesn't matter.
11988
11989 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
11990 that causes compilation to fail on pre-C99 compilers.
11991

12002
120032012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
12004
12005 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.

12007 (PSEUDOVECTOR_SIZE_BITS): New constant.
12008 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
12009 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
12010 change in pvec_type.
12011 (PSEUDOVECTOR_TYPEP): New macro.
12012 (TYPED_PSEUDOVECTORP): Use it.

12015 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
12016 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
12017 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
12018 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
12019 (sweep_vectors): Use it. Use local var `total_bytes' instead of
12020 abusing vector->header.next.nbytes.
12021 (live_vector_p): Use PVEC_TYPE.
12022 (mark_object): Adapt code to extract pvectype. Use switch.
12023
120242012-07-04 Paul Eggert <eggert@cs.ucla.edu>
12025
12026 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
12027 Tighten new eassert a bit.
12028
120292012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
12030
12031 Fix compilation with --enable-gcc-warnings and -O1
12032 optimization level.
12033 * doprnt.c (doprnt): Change type of tem to int, initialize
12034 to avoid compiler warning. Add eassert.
12035 * search.c (simple_search): Initialize match_byte to avoid
12036 compiler warning. Add eassert.
12037
120382012-07-04 Paul Eggert <eggert@cs.ucla.edu>
12039
12040 Avoid weird behavior with large horizontal scrolls.
12041 Without this change, for example, large hscroll values would
12042 mess up Emacs's display on Fedora 15 x86, presumably due to
12043 overflows in int calculations in the display code.
12044 Also, if buffers had long lines, Emacs would freeze.
12045 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
12046 (set_window_hscroll): New function, containing the old guts of
12047 Fset_window_hscroll. Return the clipped value.
12048 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
12049 This avoids the need to check against PTRDIFF_MAX.
12050
12051 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
12052
120532012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
12054
12055 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
12056
120572012-07-04 Paul Eggert <eggert@cs.ucla.edu>
12058
12059 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
12060 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
12061 since GCC 4.4.6 issues a bogus warning for them.
12062
12063 Fix bugs in file timestamp newness comparisons.
12064 * fileio.c (Ffile_newer_than_file_p):
12065 * lread.c (Fload): Use full timestamp resolution of files,
12066 not just the 1-second resolution, so that files that are only
12067 slightly newer still count as newer.
12068 * fileio.c (Ffile_newer_than_file_p): Don't assume file
12069 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
12070
120712012-07-03 Paul Eggert <eggert@cs.ucla.edu>
12072
12073 * fileio.c: Improve handling of file time marker. (Bug#11852)
12074 (special_mtime): New function.
12075 (Finsert_file_contents, Fverify_visited_file_modtime):
12076 Use it to set special mtime values consistently.
12077
120782012-07-03 Andreas Schwab <schwab@linux-m68k.org>
12079
12080 * fileio.c (Finsert_file_contents): Properly handle st_mtime
12081 marker for non-existing file. (Bug#11852)
12082
120832012-07-03 Glenn Morris <rgm@gnu.org>
12084
12085 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
12086 and did not make it into globals.h).
12087
120882012-07-03 Tom Tromey <tromey@redhat.com>
12089
12090 * window.c (Fset_window_margins, Fset_window_fringes)

12133
12134 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
12135 values which aren't power of 2.
12136 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
12137 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
12138 accordingly.
12139
121402012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
12141
12142 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

12145
121462012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
12147
12148 * alloc.c (allocate_vector_block): Remove redundant
12149 calls to mallopt if DOUG_LEA_MALLOC is defined.

12160
12161 Cleanup basic buffer management.
12162 * buffer.h (struct buffer): Change layout to use generic vector
12163 marking code. Fix some comments. Change type of 'clip_changed'
12164 to bitfield. Remove unused #ifndef old.
12165 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
12166 (GET_OVERLAYS_AT): Fix indentation.
12167 (for_each_per_buffer_object_at): New macro.
12168 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
12169 (Fbuffer_local_variables): Use it.
12170 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
12171 * alloc.c (allocate_buffer): Adjust to match new layout of
12172 struct buffer. Fix comment.
12173 (mark_overlay): New function.
12174 (mark_buffer): Use it. Use mark_vectorlike to mark normal
12175 Lisp area of struct buffer.
12176 (mark_object): Use it. Adjust marking of misc objects
12177 and related comments.
12178
121792012-07-02 Paul Eggert <eggert@cs.ucla.edu>
12180
12181 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
12182 wrapper that is not needed because the wrapped code is a no-op (zero
12183 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
12184 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
12185
121862012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
12187
12188 * alloc.c (mark_buffer): Simplify. Remove prototype.
12189 (mark_object): Add comment. Reorganize marking of vector-like
12190 objects. Use CHECK_LIVE for all vector-like objects except buffers
12191 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
12192 Avoid redundant calls to mark_vectorlike for bool vectors.
12193
121942012-06-30 Glenn Morris <rgm@gnu.org>
12195
12196 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
12197
12198 * epaths.in (PATH_SITELOADSEARCH): New.
12199 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
12200 This is rather than relying on --enable-locallisppath elements
12201 having "site-lisp" in their names. (Bug#10208#25, 11658)
12202
122032012-06-30 Eli Zaretskii <eliz@gnu.org>
12204

12208
12209 * sysselect.h [DOS_NT]: Don't include sys/select.h.
12210 (pselect) [!MS_DOS]: Redirect to sys_select.
12211
12212 * sysdep.c: Don't include dos.h and dosfns.h.
12213
12214 * process.c (sys_select):
12215 * msdos.c (sys_select): Accept one more argument and ignore it.
12216
12217 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
12218 adapt data types and code to that.
12219
12220 * dosfns.c:
12221 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
12222 which clashes with the gnulib function of the same name.
12223
122242012-06-30 Andreas Schwab <schwab@linux-m68k.org>
12225
12226 * font.c (font_style_to_value, font_style_symbolic)
12227 (font_prop_validate_style): Add type checks for values in
12228 font_style_table.
12229
12230 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
12231 argument.
12232 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
12233 uses.
12234
122352012-06-29 Eli Zaretskii <eliz@gnu.org>
12236
12237 * xdisp.c (try_window_id): Undo last change.
12238
12239 * w32.c (getwd): Adjust commentary about startup_dir.
12240 (init_environment): Always call sys_access, even in non-MSVC
12241 builds. Don't chdir to the directory of the Emacs executable.
12242 This undoes code from 1997 which was justified by the need to
12243 "avoid conflicts when removing and renaming directories". But its
12244 downside was that every relative file name was being interpreted
12245 relative to the directory of the Emacs executable, which can never
12246 be TRT. In particular, it broke sys_access when called with
12247 relative file names.
12248 (sys_access): Map GetLastError to errno.
12249
122502012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
12251
12252 * window.h (struct window): Change type of 'fringes_outside_margins'
12253 to bitfield. Fix comment. Adjust users accordingly.
12254 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
12255 Adjust comment.
12256 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
12257 to ptrdiff_t.
12258
122592012-06-29 Andreas Schwab <schwab@linux-m68k.org>

12261 * gnutls.c (emacs_gnutls_handshake):
12262 Add QUIT to make the loop interruptible.
12263
122642012-06-29 Glenn Morris <rgm@gnu.org>
12265

12285 Avoid integer overflow on scroll-left and scroll-right.
12286 * window.c (HSCROLL_MAX): New macro.
12287 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
12288 overflow when requested scroll falls outside ptrdiff_t range.
12289
122902012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
12291
12292 * window.h (struct window): Change type of 'hscroll',
12293 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
12294 'last_modified' and 'last_overlay_modified' to EMACS_INT.
12295 Adjust users accordingly.
12296 * xdisp.c (try_cursor_movement): Replace type check with eassert.
12297 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'

12431
12432 * alloc.c: Remove build_string.
12433 * lisp.h: Define build_string as static inline. This provides

12435 function is called with compile-time constant argument.
12436 * image.c (imagemagick_error): Convert to build_string.

12442 Use sprintf return value instead of invoking strlen on result.
12443 In the old days this wasn't portable, since some sprintf
12444 implementations returned char *. But they died out years ago and
12445 Emacs already assumes sprintf returns int.
12446 Similarly for float_to_string.
12447 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

12455 Use sprintf or float_to_string result to avoid need to call strlen.
12456 * data.c (Fnumber_to_string):
12457 Use make_unibyte_string, since the string must be ASCII.
12458 * lisp.h, print.c (float_to_string): Now returns int length.
12459 * term.c (produce_glyphless_glyph):
12460 Use sprintf result rather than recomputing it.
12461

124932012-06-25 Dmitry Antipov <dmantipov@yandex.ru>

12561 * keyboard.c (kbd_buffer_get_event):
12562 * process.c (Faccept_process_output):

12564 This improves on the previous patch, which introduced a bug
12565 when time_t is unsigned and as wide as intmax_t.

126312012-06-22 Paul Eggert <eggert@cs.ucla.edu>
12632
12633 Support higher-resolution time stamps (Bug#9000).
12634 The time stamps are only nanosecond-resolution at the C level,
12635 since that's the best that any real-world system supports now.
12636 But they are picosecond-resolution at the Lisp level, as that's
12637 easy, and leaves room for future OS improvements.
12638
12639 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
12640 (LIBES): Use it.
12641
12642 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
12643 Don't get current time unless it's needed.
12644
12645 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
12646 now provides it if it's absent.
12647 (start_atimer): Port to higher-res time stamps.
12648 Check for time stamp overflow. Don't get current time more
12649 often than is needed.
12650
12651 * buffer.h (struct buffer): Buffer modtime now has high resolution.
12652 Include systime.h, not time.h.
12653 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
12654
12655 * dired.c: Include stat-time.h.
12656 (Ffile-attributes): File times now have higher resolution.
12657
12658 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
12659 (struct image): Timestamp now has higher resolution.
12660
12661 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
12662 has at least microseconds now. All uses removed.
12663 (update_frame, update_single_window, update_window, update_frame_1)
12664 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
12665 (duration_to_sec_usec): Remove; no longer needed.

12671 time stamps.
12672 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
12673 (decode_time_components, lisp_seconds_argument): New functions.
12674 (make_time): Now static.
12675 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
12676 Report an error if the time is invalid, rather than having the caller
12677 do that.
12678
12679 * fileio.c: Include <stat-time.h>
12680 (Fcopy_file): Copy higher-resolution time stamps.
12681 Prefer to set the time stamp via a file descriptor if that works.
12682 (Fset_file_times, Finsert_file_contents, Fwrite_region)
12683 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
12684 (Fvisited_file_modtime, Fset_visited_file_modtime):
12685 Support higher-resolution time stamps.
12686
12687 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
12688
12689 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
12690
12691 * image.c (prepare_image_for_display, clear_image_cache)
12692 (lookup_image): Port to higer-resolution time stamps.
12693
12694 * keyboard.c (start_polling, bind_polling_period):
12695 Check for time stamp overflow.
12696 (read_char, kbd_buffer_get_event, timer_start_idle)
12697 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
12698 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
12699 Port to higher-resolution time stamps. Do not assume time_t is signed.
12700 (decode_timer): New function. Timers are now vectors of length 9,
12701 not 8, to accommodate the picosecond component.
12702 (timer_check_2): Use it.
12703
12704 * nsterm.m (select_timeout, timeval_subtract): Remove.
12705 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
12706 as they're a bit more accurate and handle overflow better.
12707 (ns_select): Change prototype to be compatible with pselect.
12708 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
12709 * nsterm.h (ns_select): Adjust prototype.
12710
12711 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
12712 us-resolution time stamps.
12713 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
12714
12715 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
12716
12717 * lisp.h (time_overflow): New decl.
12718 (wait_reading_process_output): First arg is now intmax_t, not int,
12719 to accommodate larger waits.
12720
12721 * process.h (struct Lisp_Process.read_output_delay):
12722 Now counts nanoseconds, not microseconds.
12723 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
12724 EMACS_HAS_USECS.
12725 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
12726 (wait_reading_process_output):
12727 Port to ns-resolution time stamps.
12728 (Faccept_process_output, wait_reading_process_output):
12729 Check for time stamp overflow. Do not assume time_t is signed.
12730 (select_wrapper): Remove; we now use pselect.
12731 (Fprocess_attributes): Now generates ns-resolution time stamps.
12732
12733 * sysdep.c: Include utimens.h. Don't include utime.h
12734 or worry about struct utimbuf; gnulib does that for us now.
12735 (gettimeofday): Remove; gnulib provides a substitute.
12736 (make_timeval): New function.
12737 (set_file_times): Now sets ns-resolution time stamps.
12738 New arg FD; all uses changed.
12739 (time_from_jiffies, ltime_from_jiffies, get_up_time)
12740 (system_process_attributes):
12741 Now returns ns-resolution time stamp. All uses changed.
12742 Check for time stamp overflow.
12743
12744 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
12745 provides a substitute now.
12746
12747 * systime.h: Include timespec.h rather than sys/time.h and time.h,
12748 since it guarantees struct timespec.
12749 (EMACS_TIME): Now struct timespec, so that we can support
12750 ns-resolution time stamps.
12751 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
12752 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
12753 (EMACS_USECS): Remove.
12754 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
12755 so multiply the arg by 1000 before storing it.
12756 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
12757 New macros.
12758 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
12759 Port to ns-resolution time stamps.

12761 (EMACS_TIME_SIGN): New macro.
12762 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
12763 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
12764 (set_file_times, make_time, lisp_time_argument): Adjust signature.
12765 (make_timeval, make_lisp_time, decode_time_components): New decls.
12766 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
12767 that it mishandled time_t overflow. You can't compare by subtracting!
12768 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
12769 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
12770
12771 * term.c: Include <sys/time.h>.
12772 (timeval_to_Time): New function, for proper overflow wraparound.
12773 (term_mouse_position, term_mouse_click): Use it.
12774
12775 * undo.c (record_first_change): Support higher-resolution time stamps
12776 in the undo buffer.
12777 (Fprimitive_undo): Use them when restoring time stamps.
12778
12779 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
12780 (w32_get_internal_run_time):
12781 Port to higher-resolution Emacs time stamps.
12782 (ltime): Now accepts single 64-bit integer, as that's more convenient
12783 for callers.
12784
12785 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
12786
12787 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
12788 for compatibility with pselect. Support ns-resolution time stamps.
12789
12790 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
12791
12792 * xselect.c (wait_for_property_change, x_get_foreign_selection):
12793 Check for time stamp overflow, and support ns-resolution time stamps.
12794
12795 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
12796 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
12797 (timeval_subtract): Remove; no longer needed.
12798 (XTflash, XTring_bell, x_wait_for_event):
12799 Port to ns-resolution time stamps. Don't assume time_t is signed.

128052012-06-22 Eli Zaretskii <eliz@gnu.org>
12806
12807 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
12808 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
12809 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
12810 staticidx goes up to 1597 out of 1600 = 0x640.)
12811
128122012-06-20 Paul Eggert <eggert@cs.ucla.edu>
12813
12814 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
12815 Otherwise, the umask might be mistakenly 0 while handling input signals.
12816
128172012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>

12825 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
12826 access to `contents' member of Lisp_Vector objects with AREF and ASET
12827 where appropriate.

12835 frame's selected window and its terminal's top-frame.
12836 (unwind_format_mode_line): Restore them.
12837 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
12838 Callers changed.
12839 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
12840 since tty frames can be explicitly named.
12841 (prepare_menu_bars): Likewise.
12842
12843 * term.c (Ftty_top_frame): New function.
12844
128452012-06-18 Paul Eggert <eggert@cs.ucla.edu>
12846
12847 Port byte-code-meter to modern targets.
12848 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
12849 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
12850 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
12851 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
12852 (METER_1, METER_2): Simplify.
12853
128542012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
12855

12857
128582012-06-18 Martin Rudalics <rudalics@gmx.at>
12859
12860 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
12861 gets killed during executing of this function (Bug#11665).
12862 Try to always return Qt when the buffer has been actually killed.
12863 (Vkill_buffer_query_functions): In doc-string say that functions
12864 run by this hook should not change the current buffer.
12865
128662012-06-18 Paul Eggert <eggert@cs.ucla.edu>
12867
12868 Fix recently-introduced process.c problems found by static checking.
12869 * process.c (write_queue_push, write_queue_pop, send_process):
12870 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
12871 (write_queue_pop): Fix pointer signedness problem.
12872 (send_process): Remove unused local.
12873

128862012-06-17 Paul Eggert <eggert@cs.ucla.edu>
12887
12888 * lisp.h (eassert): Assume C89 or later.
12889 This removes the need for CHECK.
12890 (CHECK): Remove. Its comments about always evaluating its
12891 argument were confusing, as 'eassert' typically does not evaluate
12892 its argument.
12893
12894 * coding.c (produce_chars): Use ptrdiff_t, not int.
12895
12896 * xterm.c (x_draw_underwave): Check for integer overflow.

12989
12990 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
12991 If all the glyphs of the glyph row came from strings, and we have no
12992 cursor positioning clues, put the cursor on the first glyph of the
12993 row.
12994 (handle_face_prop): Use chunk-relative overlay string index when
12995 indexing into it->string_overlays array. (Bug#11653)
12996 (set_cursor_from_row): Use the leftmost glyph as GLYPH_BEFORE, not

13020 (LISP_INT1_TAG, enum Lisp_Type, XINT, XUINT, make_number):
13021 Simplify under the assumption that USE_2_TAGS_FOR_INTS is defined.
13022 (INTTYPEBITS): New macro, for clarity.
13023 (INTMASK, MOST_POSITIVE_FIXNUM): Use it.
13024 (LISP_INT1_TAG, LISP_STRING_TAG, LISP_INT_TAG_P):

13026 (TYPEMASK, XINT) [USE_LSB_TAG]: Remove unnecessary cast.
13027 (make_number) [!USE_LSB_TAG]: Use INTMASK; that's simpler.

13075 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
13076 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
13077 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
13078 -DUSE_LSB_TAG=0, to override the automatically-selected default.
13079 USE_LSB_TAG now is always defined to be either 0 or 1.
13080 All uses changed.
13081 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
13082 code works fine either way, and efficiency is not a concern here,
13083 as the union type is for debugging, not for production.
13084 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
13085 Use an inline function on all platforms when using the union type,
13086 since this is simpler and 'static inline' can be used portably
13087 within Emacs now.
13088 (LISP_INITIALLY_ZERO): New macro.
13089 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.

13172 * xdisp.c (vmessage): Treat frame message as multibyte.
13173 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
13174 would generate the diagnostic "Making \302\247 buffer-local while
13175 let-bound!".
13176

13230 * doprnt.c (doprnt): Truncate multibyte char correctly.
13231 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
13232 would mishandle a string argument "Xc" if X was a multibyte
13233 character of length 2: it would truncate after X's first byte
13234 rather than including all of X.
13235
132362012-06-06 Chong Yidong <cyd@gnu.org>
13237

13281 and DEFVAR it. Update all users.
13282
132832012-06-02 Paul Eggert <eggert@cs.ucla.edu>
13284
13285 * minibuf.c (Fassoc_string): Remove duplicate declaration.
13286
13287 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:

13303 bitfields where appropriate, remove unused fields.
13304 * window.h (struct window): Remove unused 'last_mark_x' and
13305 'last_mark_y' fields. Rename 'mini_p' field to 'mini',

13318
133192012-05-31 Eli Zaretskii <eliz@gnu.org>
13320
13321 * xdisp.c (handle_stop): Detect whether we have overlay strings
13322 loaded by testing it->current.overlay_string_index to be
13323 non-negative, instead of checking whether n_overlay_strings is
13324 positive. (Bug#11587)
13325

13331
133322012-05-31 Eli Zaretskii <eliz@gnu.org>
13333
13334 * search.c (search_buffer): Remove calls to
13335 r_alloc_inhibit_buffer_relocation, as it is now called by
13336 maybe_unify_char, which was the cause of relocation of buffer text
13337 in bug#11519.
13338
133392012-05-31 Eli Zaretskii <eliz@gnu.org>
13340
13341 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
13342 for the duration of call to load_charset, to avoid problems with
13343 callers of maybe_unify_char that access buffer text through C
13344 pointers.
13345
13346 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
13347 decrement the inhibition flag, instead of just setting or
13348 resetting it.

13351
13352 Remove obsolete '#define static' cruft.
13353 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
13354 This #undef was "temporary" in 2000; it is no longer needed

13356 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
13357 (gray_bitmap_bits): Remove; no longer needed.
13358 All uses replaced with definiens.

13360
133612012-05-30 Paul Eggert <eggert@cs.ucla.edu>
13362

13364 The following changes affect the code only when profiling.
13365 * dispnew.c (__executable_start): Rename from safe_bcopy.
13366 Define only on platforms that need it.
13367 * emacs.c: Include <sys/gmon.h> when profiling.
13368 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
13369 (__executable_start): Remove decl, since lisp.h does it now.
13370 (safe_bcopy): Remove decl; no longer has that name.
13371 (main): Coalesce #if into single bit of code, for simplicity.
13372 Cast pointers to uintptr_t, since standard libraries want integers
13373 and not pointers.
13374 * lisp.h (__executable_start): New decl.
13375
133762012-05-31 Glenn Morris <rgm@gnu.org>
13377

13386
13387 * alloc.c, lisp.h (make_pure_vector): Now static.
13388
133892012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
13390

13401 Do not create empty overlays with the evaporate property (Bug#9642).
13402 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
13403 Bug#9642, but explicitly check that the buffer the overlay would
13404 be moved to is live and rearrange lines to make sure that errors
13405 will not put the overlay in an inconsistent state.
13406 (Fdelete_overlay): Cosmetics.
13407
134082012-05-28 Eli Zaretskii <eliz@gnu.org>
13409

13411 (x_raise_frame): Use handle returned by DeferWindowPos, which
13412 could be different from the original one.
13413 Call my_bring_window_to_top instead of my_set_foreground_window.
13414 (Bug#11513)
13415
13416 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
13417 by calling BringWindowToTop.
13418
13419 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
13420 (WM_EMACS_END): Increase by one.

13423
13424 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
13425 This avoids undefined behavior that might cause the eassert
13426 to not catch an out-of-range value.
13427
134282012-05-28 Juanma Barranquero <lekktu@gmail.com>
13429

13441
134422012-05-27 Paul Eggert <eggert@cs.ucla.edu>
13443
13444 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
13445 Only r_alloc_inhibit_buffer_relocation needed to be added;
13446 the others were already declared.
13447
13448 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
13449 before checking whether it's out of range. Put the check inside
13450 eassert. See
13451 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
13452
134532012-05-27 Ken Brown <kbrown@cornell.edu>
13454
13455 * callproc.c (Fcall_process): Restore a line that was accidentally
13456 commented out in the 2011-02-13 change (bug#11547).
13457
134582012-05-27 Eli Zaretskii <eliz@gnu.org>
13459
13460 * lisp.h [REL_ALLOC]: Add prototypes for external functions
13461 defined on ralloc.c.
13462
13463 * buffer.c [REL_ALLOC]: Remove prototypes of

13465 they are now on lisp.h.
13466
13467 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
13468
13469 * search.c (search_buffer): Use it to inhibit relocation of buffer
13470 text while re_search_2 is doing its job, because re_search_2 is
13471 passed C pointers to buffer text. (Bug#11519)
13472
13473 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
13474 Update value to 24.
13475
13476 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
13477 state after an additional call to move_it_in_display_line_to, keep
13478 the values of it->max_ascent and it->max_descent found for the
13479 entire line.
13480 (pos_visible_p): Revert the comparison against bottom_y to what it
13481 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
13482 (Bug#11464)
13483
134842012-05-26 Paul Eggert <eggert@cs.ucla.edu>
13485
13486 Fix coding-related core dumps with gcc -ftrapv.
13487 The code was computing A - B, where A and B are pointers, and B is
13488 random garbage. This can lead to core dumps on platforms that
13489 have special pointer registers, and it also leads to core dumps on
13490 x86-64 when compiled with gcc -ftrapv. The fix is to compute
13491 A - B only when B is initialized properly.
13492 * coding.c (coding_set_source, coding_set_destination): Return void.
13493 (coding_change_source, coding_change_destinations): New functions,
13494 with the old behaviors of coding_set_source and coding_set_destination.
13495 All callers that need an offset changed to use these new functions.
13496

13505 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
13506
13507 * w32console.c: Include window.h.
13508 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
13509 New functions.
13510 (initialize_w32_display): Initialize mouse-highlight data.
13511
13512 * w32inevt.c: Include termchar.h and window.h.
13513 (do_mouse_event): Support mouse-autoselect-window. When the mouse
13514 moves, call note_mouse_highlight. If help_echo changed, call
13515 gen_help_event to produce help-echo message in the echo area.
13516 Call clear_mouse_face if mouse_face_hidden is set in the mouse
13517 highlight info.
13518
135192012-05-26 Paul Eggert <eggert@cs.ucla.edu>
13520
13521 * lread.c (read1): Simplify slightly to avoid an overflow warning
13522 with GCC 4.7.0 on x86-64.

135242012-05-26 Eli Zaretskii <eliz@gnu.org>
13525
13526 * bidi.c (bidi_mirror_char): Revert last change: an int is
13527 definitely wide enough here.
13528
135292012-05-25 Paul Eggert <eggert@cs.ucla.edu>
13530
13531 Fix integer width and related bugs (Bug#9874).
13532 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
13533 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
13534 (string_bytes, check_sblock, allocate_string_data):
13535 (compact_small_strings, Fmake_bool_vector, make_string)
13536 (make_unibyte_string, make_multibyte_string)
13537 (make_string_from_bytes, make_specified_string)
13538 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
13539 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
13540 (mark_vectorlike):

13544 (inhibit_garbage_collection, Fgarbage_collect):
13545 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13546 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
13547 int might not be wide enough.

13563 (Foverlay_recenter, last_overlay_modification_hooks_used)
13564 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
13565 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13566 (validate_region): Omit unnecessary test for b <= e,
13567 since that's guaranteed by the previous test.
13568 (adjust_overlays_for_delete): Avoid pos + length overflow.
13569 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
13570 (report_overlay_modification):
13571 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13572 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
13573 Omit pointer cast, which isn't needed anyway, and doesn't work
13574 after the EMACS_INT -> ptrdiff_t change.
13575 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
13576 * buffer.h: Adjust decls to match defn changes elsewhere.
13577 (struct buffer_text, struct buffer):

13581 not int, to avoid needless 32-bit limit on 64-bit hosts.
13582 (exec_byte_code): Use tighter memory-full test, one that checks
13583 for alloca overflow. Don't compute the address of the object just
13584 before an array, as that's not portable. Use EMACS_INT, not
13585 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
13586 * callint.c (Fcall_interactively):
13587 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13588 * callproc.c (call_process_kill, Fcall_process):
13589 Don't assume pid_t fits into an Emacs fixnum.
13590 (call_process_cleanup, Fcall_process, child_setup):

13598 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
13599 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13600 (casify_object): Avoid integer overflow when overallocating buffer.
13601 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
13602 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
13603 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
13604 * category.h (CATEGORYP): Don't assume arg is nonnegative.
13605 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
13606 integers are now checked earlier. All uses replaced with XINT.
13607 (ccl_driver):
13608 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13609 For CCL_MapSingle, check that content and value are in int range.
13610 (ccl_driver, Fregister_code_conversion_map):
13611 Check that Vcode_version_map_vector is a vector.
13612 (resolve_symbol_ccl_program): Check that vector header is in range.
13613 Always copy the vector, so that we can check its contents reliably
13614 now rather than having to recheck each instruction as it's being
13615 executed. Check that vector words fit in 'int'.
13616 (ccl_get_compiled_code, Fregister_ccl_program)
13617 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
13618 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
13619 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
13620 contents are in range.
13621 (Fccl_execute_on_string): Check that status is in range.
13622 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
13623 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
13624 Accept and return EMACS_INT, not int, because callers can pass values
13625 out of 'int' range.

13631 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13632 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
13633 avoid mishandling large integers.
13634 * character.h: Adjust decls to match defn changes elsewhere.
13635 * charset.c (load_charset_map_from_file, find_charsets_in_text)

13640 Don't assume fixnum fits in int.
13641 (load_charset_map_from_vector, Fmap_charset_chars):
13642 Remove now-unnecessary CHECK_NATNUMs.
13643 (Fdefine_charset_internal): Check ranges here, more carefully.
13644 Don't rely on undefined behavior with signed left shift overflow.
13645 Don't assume unsigned int fits into fixnum, or that fixnum fits
13646 into unsigned int. Don't require max_code to be a valid fixnum;
13647 that's not true for gb10830 4-byte on a 32-bit host. Allow
13648 invalid_code to be a cons, for the same reason. Require code_offset
13649 to be a character. Avoid int overflow if max_char is close
13650 to INT_MAX.
13651 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
13652 this is intended anyway and avoids some undefined behavior.
13653 (load_charset_map): Pass unsigned, not int, as 2nd arg of
13654 INDEX_TO_CODE_POINT, as that's what it expects.
13655 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
13656 * charset.h (DECODE_CHAR): Return int, not unsigned;
13657 this is what was intended anyway, and it avoids undefined behavior.
13658 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
13659 integer-overflow issues.
13660 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
13661 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
13662 where the argument is EMACS_INT, and this behavior is not intended.
13663 * chartab.c (Fmake_char_table, Fset_char_table_range)
13664 (uniprop_get_decoder, uniprop_get_encoder):
13665 Don't assume fixnum fits in int.
13666 * cmds.c (move_point): New function, that does the gist of
13667 Fforward_char and Fbackward_char, but does so while checking
13668 for integer overflow more accurately.
13669 (Fforward_char, Fbackward_char): Use it.
13670 (Fforward_line, Fend_of_line, internal_self_insert)
13671 (internal_self_insert):
13672 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

13731 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
13732 Do not attempt to compute the address of the object just before a

14353 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
14354
143552012-05-22 Paul Eggert <eggert@cs.ucla.edu>
14356
14357 Remove src/m/*.
14358 This directory predates autoconf and is no longer needed nowadays.
14359 Move its few remaining bits of functionality to where they're needed.
14360 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
14361 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
14362 * m/template.h: Remove.
14363 * Makefile.in (M_FILE): Remove. All uses removed.
14364 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
14365 * lisp.h (USE_LSB_TAG):
14366 * mem-limits.h (EXCEEDS_LISP_PTR):
14367 Use VAL_MAX, not VALBITS, in #if.
14368 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.

14370 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
14371 (BITS_PER_EMACS_INT): New constants, replacing
14372 what used to be in config.h, but not useful in #if.
14373 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
14374 define them any more.
14375 (VAL_MAX): New macro.
14376 (VALMASK): Use it.
14377 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
14378 BITS_PER_EMACS_INT, in #if.
14379 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)

14386
143872012-05-21 Paul Eggert <eggert@cs.ucla.edu>
14388
14389 Assume C89 or later.

14397 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.

14408
14409 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)

14430
14431 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
14432 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
14433
14434 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
14435 reference to image_cache->refcount.
14436 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
14437
144382012-05-17 Juri Linkov <juri@jurta.org>

14442 (Fword_search_forward_lax): Move functions to isearch.el
14443 (bug#10145, bug#11381).
14444
144452012-05-16 Paul Eggert <eggert@cs.ucla.edu>
14446
14447 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
14448
144492012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
14450
14451 * lread.c (init_obarray): Declare Qt and Qnil as special.
14452
144532012-05-14 Glenn Morris <rgm@gnu.org>
14454
14455 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
14456 Put "libexec" before "bin", for the sake of init_callproc_1.
14457
144582012-05-14 Paul Eggert <eggert@cs.ucla.edu>
14459
14460 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
14461
14462 * unexaix.c: Port to more-recent AIX compilers.
14463 (report_error, report_error_1, make_hdr, copy_sym)
14464 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
14465 Make arguments const char *, not char *, to avoid violations of C
14466 standard and to fix some AIX warnings reported by Gilles Pion.
14467
144682012-05-14 Eli Zaretskii <eliz@gnu.org>
14469
14470 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
14471 already have overlays loaded.
14472 (handle_single_display_spec): Before returning without displaying
14473 fringe bitmap, synchronize the bidi iterator with the main display
14474 iterator, by calling iterate_out_of_display_property.
14475 (iterate_out_of_display_property): Detect buffer iteration by
14476 testing that it->string is a Lisp string.
14477 (get_next_display_element): When the current object is exhausted,
14478 and there's something on it->stack, call set_iterator_to_next to
14479 proceed with what's on the stack, instead of returning zero.
14480 (set_iterator_to_next): If called at the end of a Lisp string,
14481 proceed to consider_string_end without incrementing string
14482 position. Don't increment display vector index past the end of
14483 the display vector. (Bug#11417)
14484 (pos_visible_p): Don't report a position visible when move_it_to
14485 stopped at the last line of window, which happens to be scanned
14486 backwards by the bidi iteration. (Bug#11464)
14487
144882012-05-14 Eli Zaretskii <eliz@gnu.org>
14489
14490 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
14491 and right-margin display specs even if the spec is invalid or we
14492 are on a TTY, and thus unable to display on the fringes.
14493 That's because the text with the property will not be displayed anyway,
14494 so we need to signal to the caller that this is a "replacing"
14495 display spec. This fixes display when the spec is invalid or we
14496 are on a TTY.
14497
144982012-05-14 Paul Eggert <eggert@cs.ucla.edu>
14499
14500 * unexaix.c (make_hdr): Fix typo in prototype.
14501 This bug broke the build on AIX. Problem reported by Gilles Pion.

14504
14505 * keyboard.c (kbd_buffer_get_event): Read special events also in

14517
14518 * Makefile.in (MKDIR_P): New, set by configure.
14519 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.

14525 * w32fns.c (hourglass_started):
14526 * xdisp.c (hourglass_started): Remove.
14527
145282012-05-10 Juanma Barranquero <lekktu@gmail.com>
14529

145332012-05-10 Paul Eggert <eggert@cs.ucla.edu>
14534
14535 * xgselect.c (xg_select): Put maxfds+1 into a var.
14536 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
14537
14538 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
14539
145402012-05-10 Dave Abrahams <dave@boostpro.com>
14541
14542 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
14543 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
14544
145452012-05-09 Michael Albinus <michael.albinus@gmx.de>
14546
14547 * dbusbind.c (xd_registered_buses): New internal Lisp object.
14548 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.

14554 Untag more efficiently if USE_LSB_TAG.
14555 This is based on a proposal by YAMAMOTO Mitsuharu in
14556 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
14557 For an admittedly artificial (nth 8000 longlist) benchmark on
14558 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
14559 Emacs's overall text size by 1%.
14560 * lisp.h (XUNTAG): New macro.
14561 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
14562 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
14563 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
14564 * eval.c (Fautoload):
14565 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
14566 * frame.h (XFRAME): Use XUNTAG.
14567
14568 Port recent dbusbind.c changes to 32-bit --with-wide-int.
14569 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
14570 Remove unportable assumptions about print widths of types like
14571 dbus_uint32_t.
14572 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
14573 intptr_t when converting between pointer and integer, to avoid GCC
14574 warnings about wrong width.
14575
145762012-05-09 Eli Zaretskii <eliz@gnu.org>
14577
14578 * w32proc.c (new_child): Force Windows to reserve only 64KB of
14579 stack for each reader_thread, instead of defaulting to 8MB
14580 determined by the linker. This avoids failures in creating
14581 subprocesses on Windows 7, see the discussion in this thread:
14582 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
14583
145842012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
14585
14586 Fix up display of the *Minibuf-0* buffer in the mini window.
14587 * keyboard.c (read_char): Don't clear the echo area if there's no
14588 message to clear.
14589 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
14590 contents of *Minibuf-0*) if there's no message displayed in its stead.
14591
145922012-05-07 Michael Albinus <michael.albinus@gmx.de>
14593
14594 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
14595 batch mode.

14600
146012012-05-05 Jim Meyering <meyering@redhat.com>
14602
14603 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
14604
146052012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
14606
14607 * data.c (PUT_ERROR): New macro.
14608 (syms_of_data): Use it. Add new error type `user-error'.
14609 * undo.c (user_error): New function.
14610 (Fprimitive_undo): Use it.
14611 * print.c (print_error_message): Adjust print style for `user-error'.

14614
146152012-05-03 Paul Eggert <eggert@cs.ucla.edu>
14616
14617 Do not limit current-time-string to years 1000..9999.
14618 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
14619 (Fcurrent_time_string): Support any year that is supported by the
14620 underlying localtime representation. Don't use asctime, as it
14621 has undefined behavior for years outside the range -999..9999.
14622
146232012-05-02 Paul Eggert <eggert@cs.ucla.edu>
14624
14625 Fix race conditions involving setenv, gmtime, localtime, asctime.
14626 Without this fix, interrupts could mess up code that uses these
14627 nonreentrant functions, since setting TZ invalidates existing
14628 tm_zone or tzname values, and since most of these functions return
14629 pointers to static storage.
14630 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
14631 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
14632 Grow the critical sections to include not just invoking
14633 localtime/gmtime, but also accessing these functions' results
14634 including their tm_zone values if any, and any related TZ setting.
14635 (format_time_string): Last arg is now struct tm *, not struct tm **,
14636 so that the struct tm is saved in the critical section.
14637 All callers changed. Simplify allocation of initial buffer, partly
14638 motivated by the fact that memory allocation needs to be outside
14639 the critical section.
14640
146412012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
14642
14643 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
14644 with RESET_INTERVAL.
14645
14646 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
14647 Remove duplicated buffer name initialization.
14648
146492012-05-02 Jim Meyering <jim@meyering.net>
14650
14651 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).

14654
146552012-05-02 Eli Zaretskii <eliz@gnu.org>
14656
14657 * xdisp.c (pos_visible_p): If already at a newline from the
14658 display string before the 'while' loop, don't walk back the glyphs
14659 from it3.glyph_row. Solves assertion violation when the display
14660 string begins with a newline (egg.el). (Bug#11367)
14661
146622012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
14663
14664 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
14665 Move to simple.el.

146672012-05-01 Glenn Morris <rgm@gnu.org>
14668
14669 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
14670 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
14671 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
14672 All were removed before 23.1.
14673
14674 * dispnew.c: Remove HAVE_LIBNCURSES test;
14675 it is always true on relevant platforms.
14676
14677 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
14678 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
14679

14683
14684 * .gdbinit (xpr): Remove checks for no longer existing misc types.
14685 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
14686 Remove.
14687
146882012-04-28 Paul Eggert <eggert@cs.ucla.edu>
14689
14690 Do not avoid creating empty evaporating overlays (Bug#9642).
14691 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
14692 That is, do not delete an evaporating overlay if it becomes
14693 empty after its bounds are adjusted to fit within its buffer.
14694 This fix caused other problems, and I'm reverting it until we get
14695 to the bottom of them.
14696
146972012-04-27 Chong Yidong <cyd@gnu.org>
14698
14699 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
14700
147012012-04-27 Eli Zaretskii <eliz@gnu.org>
14702
14703 * xdisp.c (pos_visible_p): If the window start position is beyond
14704 ZV, start the display from buffer beginning. Prevents assertion
14705 violation in init_iterator when the minibuffer window is scrolled
14706 via the scroll bar.
14707
14708 * window.c (window_scroll_pixel_based): Likewise.
14709
147102012-04-27 Chong Yidong <cyd@gnu.org>
14711
14712 * keymap.c (where_is_internal): Doc fix (Bug#10872).

14720
14721 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
14722 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
14723
147242012-04-26 Eli Zaretskii <eliz@gnu.org>
14725
14726 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
14727 display element, check also the underlying string or buffer
14728 character. (Bug#11341)
14729
14730 * w32menu.c: Include w32heap.h.
14731 (add_menu_item): If the call to AppendMenuW (via
14732 unicode_append_menu) fails, disable Unicode menus only if we are
14733 running on Windows 9X/Me.
14734
147352012-04-24 Andreas Schwab <schwab@linux-m68k.org>
14736
14737 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
14738 (xgetint): Add missing shift for LSB tags.
14739
147402012-04-24 Martin Rudalics <rudalics@gmx.at>
14741
14742 * keyboard.c (read_char): Don't wipe echo area for select window
14743 events: These might get delayed via `mouse-autoselect-window'
14744 (Bug#11304).
14745
147462012-04-24 Juanma Barranquero <lekktu@gmail.com>

147512012-04-23 Juanma Barranquero <lekktu@gmail.com>
14752
14753 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
14754 now a cons (bug#11311).
14755
147562012-04-23 Paul Eggert <eggert@cs.ucla.edu>
14757
14758 Do not create empty overlays with the evaporate property (Bug#9642).
14759 * buffer.c (Fmove_overlay): Delete an evaporating overlay
14760 if it becomes empty after its bounds are adjusted to fit within
14761 its buffer. Without this fix, in a nonempty buffer (let ((o
14762 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
14763 yields an empty overlay that has the evaporate property, which is
14764 not supposed to happen.
14765
14766 Fix minor GTK3 problems found by static checking.
14767 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

14782 Problem reported by Juanma Barranquero for Windows -Wunused-function.
14783
147842012-04-22 Paul Eggert <eggert@cs.ucla.edu>
14785
14786 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
14787 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
14788 (__malloc_size_t, __malloc_ptrdiff_t):
14789 Remove. All uses removed, replaced by the definiens if needed,
14790 since we can assume C89 or better now.

14799 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
14800 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
14801 Define using prototypes, not old style.
14802 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):

14865
14866 * alloc.c: Handle unusual debugging option combinations.
14867 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
14868 since the two debugging options are incompatible.

14870 is defined.
14871 (mem_init, mem_insert, mem_insert_fixup):

14887
14888 * sysdep.c (list_system_processes, system_process_attributes):

149612012-04-16 Paul Eggert <eggert@cs.ucla.edu>
14962
14963 Fix minor alloc.c problems found by static checking.
14964 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
14965 New extern decls, to avoid calling undeclared functions.
14966 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
14967 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
14968 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
14969 (NEED_MEM_INSERT): New macro.
14970 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
14971 Remove one incorrect comment and fix another.

14974 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
14975 * ralloc.c (ALIGNED, ROUND_TO_PAGE, HEAP_PTR_SIZE)
14976 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
14977 (r_alloc_sbrk): Now static.
14978
14979 Improve ralloc.c interface checking.
14980 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
14981 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
14982 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
14983 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
14984 [REL_ALLOC]: ... to here, to check interface.
14985 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
14986 Remove decls. This fixes an "It stinks!".
14987
14988 * alloc.c (which_symbols): Fix alignment issue / type clash.
14989
149902012-04-15 Andreas Schwab <schwab@linux-m68k.org>

15002
150032012-04-14 Paul Eggert <eggert@cs.ucla.edu>
15004
15005 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
15006 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
15007 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
15008 * s/netbsd.h, s/sol2-6.h:
15009 Remove definition of GC_MARK_STACK, since the default now works.
15010 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
15011 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
15012 no longer the default.
15013 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
15014
150152012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

15021
15022 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
15023 "unchanged" if its end.pos is beyond ZV. (Bug#11199)
15024
150252012-04-14 Jan Djärv <jan.h.d@swipnet.se>
15026

15037
150382012-04-11 Daniel Colascione <dancol@dancol.org>
15039
15040 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
15041 against is gone. It's better to use vfork now so that when Cygwin
15042 gains a new, working vfork, we use it automatically (bug#10398).
15043
150442012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
15045

15058 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
15059 (force_quit_count): New var.
15060 (handle_interrupt): Use it.
15061
150622012-04-10 Juanma Barranquero <lekktu@gmail.com>

15068
15069 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
15070 not just in the obarray, before snarfing them. (Bug#11036)
15071
15072 * Makefile.in ($(leimdir)/leim-list.el):
15073 Pass EMACS rather than BUILT_EMACS.
15074
150752012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
15076

15078 * process.h: Add integer `gnutls_handshakes_tried' member to
15079 process struct.
15080

15082 Add convenience `GNUTLS_LOG2i' macro.
15083
15084 * gnutls.c (gnutls_log_function2i): Convenience log function.
15085 (emacs_gnutls_read): Use new log functions,
15086 `gnutls_handshakes_tried' process member, and
15087 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
15088 attempts per process (connection).
15089
150902012-04-09 Chong Yidong <cyd@gnu.org>
15091
15092 * eval.c (Fuser_variable_p, user_variable_p_eh)
15093 (lisp_indirect_variable): Functions deleted.

150992012-04-09 Eli Zaretskii <eliz@gnu.org>
15100
15101 * xdisp.c (set_cursor_from_row): If the display string appears in
15102 the buffer at position that is closer to point than the position
15103 after the display string, display the cursor on the first glyph of
15104 the display string. Fixes cursor display when a 'display' text
15105 property immediately follows invisible text. (Bug#11094)
15106
151072012-04-09 Paul Eggert <eggert@cs.ucla.edu>
15108
15109 composite.c: use 'double' consistently
15110 * composite.c (get_composition_id): Use 'double' consistently
15111 instead of converting 'float' to 'double' and vice versa; this is
15112 easier to understand and avoids a GCC warning.
15113
151142012-04-09 Glenn Morris <rgm@gnu.org>
15115
15116 * Makefile.in: Generate leim-list with bootstrap-emacs, in

15130
151312012-04-07 Juanma Barranquero <lekktu@gmail.com>
15132
15133 * xml.c (init_libxml2_functions) [WINDOWSNT]:
15134 Remove unused local variable.
15135
151362012-04-07 Paul Eggert <eggert@cs.ucla.edu>
15137
15138 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
15139 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
15140 (mark_memory): Mark Lisp_Objects only if pointers might hide in
15141 objects, as mark_maybe_pointer will catch them otherwise.
15142 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
15143 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
15144
151452012-04-07 Paul Eggert <eggert@cs.ucla.edu>
15146
15147 Fix typo that broke non-Windows builds.
15148 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
15149
151502012-04-07 Eli Zaretskii <eliz@gnu.org>
15151
15152 Support building on MS-Windows with libxml2.

15157
15158 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
15159 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
15160 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
15161 [!WINDOWSNT]: New macros.
15162 (init_libxml2_functions, libxml2_loaded_p): New functions.
15163 (parse_region): Call fn_xmlCheckVersion instead of using the macro
15164 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
15165 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
15166 Calls xmlCleanupParser only if libxml2 was loaded (or statically
15167 linked in).
15168 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
15169 Call init_libxml2_functions before calling libxml2 functions.
15170 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
15171
15172 * emacs.c: Don't include libxml/parser.h.
15173 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
15174 xmlCleanupParser directly.
15175
15176 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
15177
151782012-04-07 Eli Zaretskii <eliz@gnu.org>
15179
15180 * indent.c (Fvertical_motion): If there is a display string at
15181 point, use it.vpos to compute how many lines to backtrack after
15182 move_it_to point. (Bug#11133)
15183
151842012-04-06 Eli Zaretskii <eliz@gnu.org>
15185
15186 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
15187 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
15188 about subtle differences between FETCH_CHAR* and STRING_CHAR*
15189 macros related to unification of CJK characters. For the details,
15190 see the discussion following the message here:
15191 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
15192
151932012-04-04 Chong Yidong <cyd@gnu.org>
15194
15195 * keyboard.c (Vdelayed_warnings_list): Doc fix.
15196
151972012-04-01 Eli Zaretskii <eliz@gnu.org>
15198
15199 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
15200 instead of alloca. (Bug#11138)
15201
152022012-04-01 Andreas Schwab <schwab@linux-m68k.org>
15203
15204 * w32menu.c (is_simple_dialog): Properly check lisp types.
15205 (Bug#11141)
15206
152072012-03-31 Eli Zaretskii <eliz@gnu.org>
15208
15209 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
15210 position we get to after a call to move_it_to fails the
15211 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
15212 only if we wind up in a string from display property. (Bug#11063)
15213
15214 * window.c (Fdelete_other_windows_internal): Invalidate the row
15215 and column information about mouse highlight, so that redisplay
15216 restores it after reallocating the glyph matrices. (Bug#7464)
15217
15218 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
15219 string comes from a `display' text property, use the buffer
15220 position of that property as if we actually saw that position in
15221 the row's glyphs.
15222 (move_it_by_lines): Remove the assertion that
15223 "it->current_x == 0 && it->hpos == 0" which can be legitimately
15224 violated when there's a before-string at the beginning of a line.
15225 (Bug#11063)
15226
152272012-03-30 Eli Zaretskii <eliz@gnu.org>
15228
15229 * xdisp.c (append_space_for_newline): If the default face was
15230 remapped, use the remapped face for the appended newline.
15231 (extend_face_to_end_of_line): Use the remapped default face for
15232 extending the face to the end of the line.
15233 (display_line): Call extend_face_to_end_of_line when the default
15234 face was remapped. (Bug#11068)
15235
152362012-03-29 Eli Zaretskii <eliz@gnu.org>
15237
15238 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

152492012-03-26 Kenichi Handa <handa@m17n.org>
15250
15251 * dispextern.h (struct glyph): Fix previous change. Change the
15252 bit length of glyphless.ch to 25 (Bug#11082).
15253
152542012-03-26 Chong Yidong <cyd@gnu.org>
15255
15256 * keyboard.c (Vselection_inhibit_update_commands): New variable.
15257 (command_loop_1): Use it; inhibit selection update for
15258 handle-select-window too (Bug#8996).
15259
152602012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
15261
15262 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
15263
152642012-03-25 Kenichi Handa <handa@m17n.org>
15265
15266 * dispextern.h (struct glyph): Change the bit length of
15267 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
15268
152692012-03-24 Eli Zaretskii <eliz@gnu.org>
15270
15271 * s/ms-w32.h (tzname): Include time.h before redirecting to
15272 _tzname. Fixes the MSVC build. (Bug#9960)
15273
152742012-03-24 Andreas Schwab <schwab@linux-m68k.org>
15275
15276 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
15277 characters.
15278
15279 * xterm.c (XTread_socket): Only modify handling_signal if
15280 !SYNC_INPUT. (Bug#11080)
15281
152822012-03-23 Eli Zaretskii <eliz@gnu.org>
15283
15284 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
15285 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
15286 when fetching a multibyte character consumes more bytes than
15287 CHAR_BYTES returns, due to unification of CJK characters in
15288 string_char. (Bug#11073)
15289
152902012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
15291
15292 * process.c (wait_reading_process_output): Handle pty disconnect

15303
153042012-03-21 Chong Yidong <cyd@gnu.org>
15305
15306 * xfaces.c (Vface_remapping_alist): Doc fix.
15307
153082012-03-20 Eli Zaretskii <eliz@gnu.org>
15309
15310 * w32proc.c (Fw32_set_console_codepage)

15313
153142012-03-20 Chong Yidong <cyd@gnu.org>
15315
15316 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
15317 to reflect default non-nil value of redisplay-dont-pause.
15318
153192012-03-19 Kenichi Handa <handa@m17n.org>
15320
15321 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
15322 it fit in a valid range (Bug#11003).
15323
153242012-03-18 Eli Zaretskii <eliz@gnu.org>
15325
15326 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
15327 that is not from display property, accept the row as a "cursor
15328 row" if one of the string's character has a non-nil `cursor'
15329 property. Fixes cursor positioning when there are newlines in
15330 overlay strings, e.g. in icomplete.el. (Bug#11035)
15331
153322012-03-12 Paul Eggert <eggert@cs.ucla.edu>
15333
15334 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).

153362012-03-12 Chong Yidong <cyd@gnu.org>
15337
15338 * eval.c (inhibit_lisp_code): Rename from
15339 inhibit_window_configuration_change_hook; move from window.c.

15342 * window.c (run_window_configuration_change_hook)
15343 (syms_of_window): Callers changed.
15344
153452012-03-11 Chong Yidong <cyd@gnu.org>
15346
15347 * keymap.c (Fkey_description): Doc fix (Bug#9700).

15392
15393 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
15394 Suggested by Stefan Monnier in
15395 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
15396 * alloc.c (widen_to_Lisp_Object): New static function.
15397 (mark_memory): Also mark Lisp_Objects by fetching pointer words
15398 and widening them to Lisp_Objects. This would work even if
15399 USE_LSB_TAG is defined and wide integers are used, which might
15400 happen in a future version of Emacs.
15401
154022012-02-25 Chong Yidong <cyd@gnu.org>
15403
15404 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

15415
154162012-02-23 Chong Yidong <cyd@gnu.org>
15417
15418 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
15419 call when setting menu-bar-lines and tool-bar-lines parameters.
15420 (unwind_create_frame_1): New helper function.
15421
15422 * window.c (inhibit_window_configuration_change_hook): New var.

15441 when computing $valmask.
15442
15443 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
15444 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
15445 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
15446 It's useless in that case, and it can cause problems on hosts
15447 that allocate halves of EMACS_INT values separately.
15448 Reported by Dan Horák. Diagnosed by Andreas Schwab in
15449 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
15450 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
15451 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
15452 it avoids undefined behavior on hosts where shifting right by more
15453 than the word width has undefined behavior.

15579 * character.c (char_width): Return EMACS_INT, not int.
15580 (char_width, c_string_width): Check for overflow when
15581 computing the width; this is possible now that individual
15582 characters can have unbounded width. Problem introduced
15583 by merge from Emacs 23 on 2012-01-19.
15584
155852012-02-02 Michael Albinus <michael.albinus@gmx.de>

15725 (Fmake_directory_internal): Use it.

16232 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
16233 Otherwise, valgrind does not work on some platforms.
16234 Problem reported by Andreas Schwab in
16235 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
16236 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
16237 is set, removing the need for VIRT_ADDRESS_VARIES.
16238 (PURE_P): Use a more-efficient implementation that needs just one
16239 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
16240 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
16241 to 4 (xorl, subq, cmpq, setbe).
16242 * alloc.c (pure): Always extern now, since that's the
16243 VIRT_ADDR_VARIES behavior.
16244 (PURE_POINTER_P): Use a single comparison, not two, for
16245 consistency with the new puresize.h.
16246 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
16247 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
16248 Remove VIRT_ADDR_VARIES no longer needed.

16253 (erase_phys_cursor, update_window_cursor, show_mouse_face)
16254 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
16255 behave as if the cursor position were at the window margin.
16256
16257 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
16258 and the cursor position is out of bounds, behave as if the cursor
16259 position were at the window margin. (Bug#10075)
16260
162612011-11-18 Chong Yidong <cyd@gnu.org>
16262
16263 * window.c (Fwindow_combination_limit): Make first argument

16279 hash values of the two rows.
16280 (copy_row_except_pointers): Preserve the used[] arrays and the
16281 hash values of the two rows. (Bug#10035)
16282 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
16283
16284 * xdisp.c (row_hash): New function, body extracted from
16285 compute_line_metrics.
16286 (compute_line_metrics): Call row_hash, instead of computing the
16287 hash code inline.
16288
16289 * dispnew.c (verify_row_hash): Call row_hash for computing the
16290 hash code of a row, instead of duplicating code from xdisp.c.

16329
163302011-11-14 Eli Zaretskii <eliz@gnu.org>
16331
16332 * xdisp.c (display_line): Move the call to
16333 highlight_trailing_whitespace before the call to
16334 compute_line_metrics, since the latter needs to see the final
16335 faces of all the glyphs to compute ROW's hash value.
16336 Fixes assertion violations in row_equal_p. (Bug#10035)
16337
163382011-11-14 Juanma Barranquero <lekktu@gmail.com>
16339
16340 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
16341 just return (bug#10044).
16342
163432011-11-12 Eli Zaretskii <eliz@gnu.org>
16344
16345 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
16346 with user-defined heap size. Bump the default size of the temacs
16347 heap to 27MB, to avoid memory warning when running temacs.
16348 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
16349
16350 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
16351 current_matrix and desired_matrix. (Bug#9990)
16352 (verify_row_hash) [XASSERTS]: New function.

16354 that the hash value of glyph rows is correct.
16355
163562011-11-12 Martin Rudalics <rudalics@gmx.at>
16357
16358 * window.h (window): Remove splits slot.

16398
16399 Avoid some portability problems by eschewing 'extern inline' functions.
16400 The trivial performance wins aren't worth the portability hassles; see

16431
16432 * w32.c (check_windows_init_file): Don't look for term/w32-win.el

16450
16451 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
16452 This is also needed for porting to any host where GC_MARK_STACK is
16453 not GC_MAKE_GCPROS_NOOPS.
16454 (which_symbols): Use it.
16455
164562011-11-07 Kenichi Handa <handa@m17n.org>
16457
16458 * coding.c (coding_set_destination): Check coding->src_pos only

16468
16469 * xmenu.c (cleanup_widget_value_tree): New function.
16470 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
16471 calling free_menubar_widget_value_tree directly (Bug#9830).
16472
164732011-11-06 Paul Eggert <eggert@cs.ucla.edu>
16474
16475 Fix some portability problems with 'inline'.

16477 (window_box_width, window_box_left, window_box_left_offset)
16478 (window_box_right, window_box_right_offset): Declare extern.
16479 Otherwise, these inline functions do not conform to C99 and
16480 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
16481 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
16482 * intervals.c (adjust_intervals_for_insertion)

16485 (static_offset_intervals): Remove.
16486 (offset_intervals): Rewrite using the old contents of
16487 static_offset_intervals. The old version didn't conform to C99

16489 identifier with static linkage.
16490
164912011-11-06 Andreas Schwab <schwab@linux-m68k.org>
16492

16511 (Fwindow_vscroll): Doc fix.
16512 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
16513 argument, since it makes no sense to pass a live window and for
16514 consistency with window-child.

16544 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
16545 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
16546 Move terminal->reference_count++ just before making the frame official
16547 (Bug#9943).
16548
16549 * nsterm.m (x_free_frame_resources): New function.
16550 (x_destroy_window): Move code to x_free_frame_resources.
16551

16554 Move terminal->reference_count++ just before making the frame
16555 official. Move initialization of image_cache_refcount and
16556 dpyinfo_refcount before calling init_frame_faces (Bug#9943).
16557
165582011-11-05 Eli Zaretskii <eliz@gnu.org>
16559
16560 Support MSVC build with newer versions of Visual Studio.
16561 * makefile.w32-in (TAGS-gmake): Don't use $(patsubst ...), as

16653 check for _NET_WM_STATE_HIDDEN (Bug#9893).
16654 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
16655 (x_handle_net_wm_state): Return what get_current_wm_state returns.
16656 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
16657
166582011-10-29 Paul Eggert <eggert@cs.ucla.edu>
16659
16660 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
16661 so that this new function doesn't get optimized away by a

16723 New functions.
16724 (w32font_open_internal, compute_metrics):
16725 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
16726 instead of calling the "wide" APIs directly.
16727

16745 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
16746 an error. Set process slots as soon as we allocate them.
16747
16748 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
16749
167502011-10-27 Chong Yidong <cyd@gnu.org>

16789
16790 * bidi.c (bidi_line_init): Initialize the next_en_type member.
16791 (bidi_resolve_explicit_1): When next_en_pos is valid for the
16792 current character, check also for next_en_type being WEAK_EN.
16793 (bidi_resolve_weak): Don't enter the expensive loop if the current
16794 position is before next_en_pos. Record the bidi type of the first
16795 non-ET, non-BN character we find, in addition to its position.
16796 (bidi_level_of_next_char): Invalidate next_en_type when
16797 next_en_pos is over-stepped.
16798

16800
16801 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
16802 * editfns.c: Rewrite current-time-zone so that it invokes
16803 the equivalent of (format-time-string "%Z") to get the time zone name.
16804 This fixes a bug when the time zone name contains characters that
16805 need converting from the system time locale to Emacs internal format.
16806 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
16807 that patch fixed format-time-string to do the conversion, but
16808 I forgot to fix current-time-zone.
16809 (format_time_string): New function, containing most of
16810 what Fformat_time_string used to contain.
16811 (Fformat_time_string): Rewrite in terms of format_time_string.
16812 This doesn't change this function's behavior.
16813 (current-time-zone): Rewrite to use format_time_string.
16814 This fixes the bug reported by Michael Schierl in
16815 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
16816 Jason Rumney's 2007-06-07 change worked around this bug, but
16817 didn't fix it.
16818 * systime.h (tzname, timezone): Remove no-longer-used declarations.
16819
168202011-10-19 Eli Zaretskii <eliz@gnu.org>
16821
16822 * xdisp.c (start_display): If the character at POS is displayed
16823 via a display vector, reset IT->current.dpvec_index to zero.
16824 (try_window_reusing_current_matrix): If a line ends in a display
16825 vector or the next line starts in a display vector, continue
16826 redrawing the window even though the character position of
16827 start_row was reached.
16828 (Bug#9771, part 2)
16829
168302011-10-18 Chong Yidong <cyd@gnu.org>
16831

168352011-10-18 Eli Zaretskii <eliz@gnu.org>
16836
16837 Fix part 3 of bug#9771.
16838 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
16839 (bidi_resolve_neutral): Don't enter the expensive loop looking for
16840 non-neutral characters if the current character is a paragraph
16841 separator (a.k.a. Newline). This avoids running the same
16842 expensive loop twice, once when we consume the preceding newline
16843 and the other time when the line actually needs to be displayed.
16844 Avoid the loop when we see neutrals on the base embedding level
16845 following a character whose directionality is the same as the
16846 paragraph's. This avoids running the expensive loop when a line
16847 ends in a long sequence of neutrals, like control characters.
16848 Add assertion against STRONG_AL type. Slightly rearrange code
16849 that determines the type of a neutral given the first non-neutral
16850 that follows it.
16851 (bidi_level_of_next_char): Set next_en_pos to zero when
16852 invalidating its info.
16853
168542011-10-17 Eli Zaretskii <eliz@gnu.org>
16855
16856 * xdisp.c (push_display_prop): Determine whether to record string
16857 or buffer position by IT->string, not by IT->method. Allow
16858 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
16859 (move_it_vertically_backward): Don't look for character position
16860 immediately after the newline when in a continuation line.
16861 (Bug#9771, part 1)
16862
168632011-10-15 Martin Rudalics <rudalics@gmx.at>

168782011-10-13 Eli Zaretskii <eliz@gnu.org>
16879
16880 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
16881 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
16882 cursor motion with <left> and <right> arrow keys.
16883
16884 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
16885 some callers set that themselves.
16886
168872011-10-12 Eli Zaretskii <eliz@gnu.org>
16888
16889 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
16890 display string and the previous row comes from the same string and
16891 is empty. (Bug#9739) (Bug#9738)
16892

169112011-10-12 Paul Eggert <eggert@cs.ucla.edu>
16912
16913 * xdisp.c (set_cursor_from_row): Simplify conditionals,
16914 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
16915
16916 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
16917 Some packages use them to denote characters with modifiers.
16918
169192011-10-11 Andreas Schwab <schwab@linux-m68k.org>
16920
16921 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
16922 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
16923 matching a pp-number. Rename parameter var to var1.

16928
169292011-10-08 Glenn Morris <rgm@gnu.org>
16930
16931 * callint.c (Fcall_interactively): Give a more explicit error for the
16932 'c' case with a non-character input. (Bug#8479)
16933
169342011-10-08 Eli Zaretskii <eliz@gnu.org>
16935

16939 lines that are hscrolled on the left.

16943
169442011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
16945
16946 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
16947 Don't advertise functionality which we discourage or doesn't work.
16948
169492011-10-07 Paul Eggert <eggert@cs.ucla.edu>
16950
16951 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
16952 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
16953 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
16954 this makes Emacs dump core during garbage collection on rare
16955 occasions. sizeof is obviously inferior to offsetof here, so
16956 stick with offsetof.
16957 (GC_POINTER_ALIGNMENT): New macro.
16958 (mark_memory): Omit 3rd (offset) arg; caller changed.

16962
16963 * keyboard.c (read_key_sequence_remapped): New var.
16964 (read_key_sequence): Compute remapping in the right buffer.
16965 (command_loop_1): Use read_key_sequence's remapping directly.

169672011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
16968
16969 * dired.c (file_name_completion): Don't expand file name.
16970 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
16971 before checking file name handler.
16972
16973 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
16974 they've been requested explicitly (bug#9591).

16981
169822011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16983
16984 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
16985 This fixes a Y2038 bug on 64-bit hosts.
16986 * buffer.c (reset_buffer):
16987 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
16988 (Fclear_buffer_auto_save_failure):
16989 Use 0, not -1, to represent an unset failure time, since time_t
16990 might not be signed.
16991
16992 Remove dependency on glibc malloc internals.
16993 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16994 Move back here from lisp.h, but with their new implementations.
16995 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16996 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
16997 * charset.c (charset_table_init): New static var.
16998 (syms_of_charset): Use it instead of xmalloc. This removes a
16999 dependency on glibc malloc internals. See Eli Zaretskii's comment in
17000 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
17001 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
17002 Move back to alloc.c.
17003 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
17004 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.

17007
17008 * nsterm.m (windowDidResize): Call x_set_window_size only when
17009 ns_in_resize is true. Otherwise set pixelwidth/height and
17010 call change_frame_size (Bug#9628).
17011

17013
17014 Port --enable-checking=all to Fedora 14 x86-64.
17015 * charset.c (syms_of_charset): Also account for glibc malloc's
17016 internal overhead when calculating the initial malloc maximum.
17017
17018 Port --enable-checking=all to Fedora 14 x86.
17019 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
17020 Move to lisp.h.
17021 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
17022 (overrun_check_realloc, overrun_check_free):
17023 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
17024 That way, xmalloc returns a properly-aligned pointer even if
17025 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
17026 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
17027 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
17028 into account when calculating the initial malloc maximum.
17029 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
17030 Move here from alloc.c, so that charset.c can use it too.
17031 Properly align; the old code wasn't right for common 32-bit hosts
17032 when configured with --enable-checking=all.
17033 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
17034 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.

17044 string at CHARPOS, return -1.
17045
17046 * bidi.c (bidi_fetch_char): When compute_display_string_end
17047 returns a negative value, treat the character as a normal
17048 character not covered by a display string. (Bug#9624)
17049
170502011-09-28 Juanma Barranquero <lekktu@gmail.com>

17055
17056 * xdisp.c (handle_invisible_prop): If invisible text ends on a

17058 character at a time. (Bug#9610)
17059 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
17060 TO_CHARPOS if the bidi iterator is at base embedding level.

17094 Default value is now t. Doc fix.
17095
17096 * indent.c (Fvertical_motion): Compute and apply the overshoot
17097 logic when moving up, not only when moving down. Fix the
17098 confusing name and values of the it_overshoot_expected variable;
17099 logic changes accordingly. (Bug#9254) (Bug#9549)
17100
17101 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
17102 CHARPOS is covered by a display string which includes newlines.

17114
17115 do not ignore write error for any output size
17116 The previous change was incomplete.
17117 While it makes emacs --batch detect the vast majority of stdout
17118 write failures, errors were still ignored whenever the output size is
17119 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
17120 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
17121 && echo FAIL: ignored write error
17122 FAIL: ignored write error
17123 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
17124 && echo FAIL: ignored write error
17125 FAIL: ignored write error
17126 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
17127
171282011-09-23 Andreas Schwab <schwab@linux-m68k.org>
17129
17130 * emacs.c (Fkill_emacs): In noninteractive mode exit
17131 non-successfully if a write error occurred on stdout. (Bug#9574)

17135 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
17136 the xassert test.
17137

17143 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
17144 a display string, extend search for cursor position to end of row.
17145 (find_row_edges): If the row ends in a newline from a display
17146 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
17147 Handle the case of a display string with multiple newlines.
17148 (Fcurrent_bidi_paragraph_direction): Fix search for previous
17149 non-empty line. Fixes confusing cursor motion with arrow keys at
17150 the beginning of a line that starts with whitespace.

17161
171622011-09-18 Eli Zaretskii <eliz@gnu.org>
17163
17164 * xdisp.c (display_line): Record maximum and minimum buffer
17165 positions even if no glyphs were produced (e.g., by a zero-width
17166 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
17167 buffer positions that will be removed from the glyph row because
17168 they don't fit.
17169 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
17170 column is beyond frame width: don't subtract 1 "pixel" when
17171 computing width of the stretch.
17172 (reseat_at_next_visible_line_start): Undo the change made on
17173 2011-09-17 that saved paragraph information and restored it after
17174 the call to `reseat'. (Bug#9545)

17213 about the current paragraph and restore it after the call to reseat.
17214
17215 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
17216 (bidi_find_paragraph_start): Search back for paragraph beginning
17217 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
17218 (bidi_move_to_visually_next): Only trigger paragraph-related
17219 computations when the last character is a newline or at EOB, not
17220 just any NEUTRAL_B. (Bug#9470)
17221
17222 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
17223 truncated lines if point is covered by a display string. (Bug#9524)

17228 (cons_to_x_long): New function.
17229 (lisp_data_to_selection_data): Use it. Correct the test for
17230 short-versus-long data; it was negated. Break out of vector
17231 loop, for efficiency, when a long datum is discovered.
17232
172332011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>

17285 (selection_data_to_lisp_data): Assume incoming selection data are
17286 signed integers, not unsigned. This is to be consistent with
17287 outgoing selection data, which was modified to use signed integers
17288 in as part of the fix to Bug#9196 in response to Jan D.'s comment
17289 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
17290 expects long, not unsigned long.

17326
17327 * fileio.c (Finsert_file_contents): If the file cannot be opened,
17328 set its "size" to -1. This will set the modtime_size field of
17329 the corresponding buffer to -1, which is what
17330 verify-visited-file-modtime expects for files that do not exist.

17336 here ...
17337 * lisp.h: ... from here. push_key_description is no longer
17338 defined in keyboard.c, so its declaration should not be in
17339 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
17340 logically belongs with push_key_description.

173582011-09-10 Eli Zaretskii <eliz@gnu.org>
17359
17360 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
17361 redisplay in small windows.
17362
173632011-09-09 Eli Zaretskii <eliz@gnu.org>
17364
17365 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
17366
173672011-09-08 Martin Rudalics <rudalics@gmx.at>
17368
17369 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
17370 Operate on live windows only.
17371
173722011-09-08 Juanma Barranquero <lekktu@gmail.com>
17373
17374 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
17375
173762011-09-07 Eli Zaretskii <eliz@gnu.org>
17377
17378 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
17379 only under bidi iteration.
17380
173812011-09-07 Jan Djärv <jan.h.d@swipnet.se>
17382
17383 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
17384
173852011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17386
17387 isnan: Fix porting problem to Solaris 10 with bundled gcc.
17388 Without this fix, the command to link temacs failed due to an
17389 undefined symbol __builtin_isnan. This is because
17390 /usr/include/iso/math_c99.h #defines isnan(x) to
17391 __builtin_isnan(x), but the bundled gcc, which identifies itself
17392 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
17393 a __builtin_isnan.
17394 * floatfns.c (isnan): #undef, and then #define to a clone of
17395 what's in data.c.
17396 (Fisnan): Always define, since it's always available now.
17397 (syms_of_floatfns): Always define isnan at the Lisp level.
17398
173992011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17400
17401 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
17402
174032011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17404
17405 * fileio.c: Fix bugs with large file offsets (Bug#9428).
17406 The previous code assumed that file offsets (off_t values) fit in
17407 EMACS_INT variables, which is not true on typical 32-bit hosts.
17408 The code messed up by falsely reporting buffer overflow in cases
17409 such as (insert-file-contents "big" nil 1 2) into an empty buffer
17410 when "big" contains more than 2**29 bytes, even though this
17411 inserts just one byte and does not overflow the buffer.
17412 (Finsert_file_contents): Store file offsets as off_t
17413 values, not as EMACS_INT values. Check for overflow when
17414 converting between EMACS_INT and off_t. When checking for
17415 buffer overflow or for overlap, take the offsets into account.
17416 Don't use EMACS_INT for small values where int suffices.
17417 When checking for overlap, fix a typo: ZV was used where
17418 ZV_BYTE was intended.
17419 (Fwrite_region): Don't assume off_t fits into 'long'.
17420 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
17421
174222011-09-05 Michael Albinus <michael.albinus@gmx.de>
17423
17424 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
17425
174262011-09-04 Paul Eggert <eggert@cs.ucla.edu>
17427
17428 sprintf-related integer and memory overflow issues (Bug#9412).
17429
17430 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
17431 (esprintf, exprintf, evxprintf): New functions.
17432 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
17433 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
17434 (modify_event_symbol): Do not assume that the length of
17435 name_alist_or_stem is safe to alloca and fits in int.
17436 (Fexecute_extended_command): Likewise for function name and binding.
17437 (Frecursion_depth): Wrap around reliably on integer overflow.
17438 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
17439 since some callers pass EMACS_INT values.
17440 (Fsingle_key_description): Don't crash if symbol name contains more
17441 than MAX_ALLOCA bytes.
17442 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
17443 (get_minibuffer): Arg is now EMACS_INT, not int.
17444 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
17445 (esprintf, exprintf, evxprintf): New decls.
17446 * window.h (command_loop_level, minibuf_level): Reflect API changes.
17447
17448 * dbusbind.c (signature_cat): New function.
17449 (xd_signature, Fdbus_register_signal):
17450 Do not overrun buffer; instead, report string overflow.
17451
17452 * dispnew.c (add_window_display_history): Don't overrun buffer.
17453 Truncate instead; this is OK since it's just a log.
17454
17455 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
17456 even if the time zone offset is outlandishly large.
17457 Don't mishandle offset == INT_MIN.
17458
17459 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
17460 when creating daemon; the previous buffer-overflow check was incorrect.
17461
17462 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
17463 which has the guts of the old verror function.
17464
17465 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
17466 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
17467
17468 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
17469 (font_unparse_xlfd): Don't blindly alloca long strings.
17470 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
17471 fits in int, when using sprintf. Use single snprintf to count
17472 length of string rather than counting it via multiple sprintfs;
17473 that's simpler and more reliable.
17474 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
17475 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
17476 sprintf, in case result does not fit in int.
17477
17478 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
17479 (fontset_from_font): Print it.
17480
17481 * frame.c (tty_frame_count): Now printmax_t, not int.
17482 (make_terminal_frame, set_term_frame_name): Print it.
17483 (x_report_frame_params): In X, window IDs are unsigned long,
17484 not signed long, so print them as unsigned.
17485 (validate_x_resource_name): Check for implausibly long names,
17486 and don't assume name length fits in 'int'.
17487 (x_get_resource_string): Don't blindly alloca invocation name;
17488 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
17489 not fit in int.
17490
17491 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
17492 (xg_check_special_colors, xg_set_geometry):
17493 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
17494
17495 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
17496 Use esprintf, not sprintf, in case result does not fit in int.
17497
17498 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
17499 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
17500 it as a large positive number.
17501 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
17502 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
17503
17504 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
17505 in case result does not fit in int.
17506
17507 * print.c (float_to_string): Detect width overflow more reliably.
17508 (print_object): Make sprintf buffer a bit bigger, to avoid potential
17509 buffer overrun. Don't assume list length fits in 'int'. Treat
17510 print length of 0 as 0, not as infinity; to be consistent with other
17511 uses of print length in this function. Don't overflow print length
17512 index. Don't assume hash table size fits in 'long', or that
17513 vectorlike size fits in 'unsigned long'.
17514
17515 * process.c (make_process): Use printmax_t, not int, to format
17516 process-name gensyms.
17517
17518 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
17519
17520 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
17521 to avoid potential buffer overrun.
17522
17523 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
17524 if X resource line is longer than 512 bytes.
17525
17526 * xfns.c (x_window): Make sprintf buffer a bit bigger
17527 to avoid potential buffer overrun.
17528
17529 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
17530
17531 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
17532
175332011-09-04 Paul Eggert <eggert@cs.ucla.edu>
17534
17535 Integer overflow fixes for scrolling, etc.
17536 Without these, Emacs silently mishandles large integers sometimes.
17537 For example, "C-u 4294967297 M-x recenter" was treated as if
17538 it were "C-u 1 M-x recenter" on a typical 64-bit host.
17539
17540 * xdisp.c (try_window_id): Check Emacs fixnum range before
17541 converting to 'int'.
17542
17543 * window.c (window_scroll_line_based, Frecenter):
17544 Check that an Emacs fixnum is in range before assigning it to 'int'.
17545 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
17546 values converted from Emacs fixnums.
17547 (Frecenter): Don't wrap around a line count if it is out of 'int'
17548 range; instead, treat it as an extreme value.
17549 (Fset_window_configuration, compare_window_configurations):
17550 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
17551
17552 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
17553 that can exceed INT_MAX. Check that EMACS_INT value is in range
17554 before assigning it to the (possibly-narrower) index.
17555 (match_limit): Don't assume that a fixnum can fit in 'int'.
17556
17557 * print.c (print_object): Use ptrdiff_t, not int, for index that can
17558 exceed INT_MAX.
17559
17560 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
17561 (Fvertical_motion): Don't wrap around LINES values that don't fit
17562 in 'int'. Instead, treat them as extreme values. This is good
17563 enough for windows, which can't have more than INT_MAX lines anyway.
17564
175652011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
17566
17567 * Require libxml/parser.h to avoid compilation warning.
17568
17569 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
17570
17571 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
17572 since this reportedly can destroy thread storage.
17573
175742011-08-30 Chong Yidong <cyd@stupidchicken.com>
17575
17576 * syntax.c (find_defun_start): Update all cache variables if
17577 exiting early (Bug#9401).
17578
175792011-08-30 Eli Zaretskii <eliz@gnu.org>
17580
17581 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
17582
17583 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
17584 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
17585 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
17586
17587 * term.c (tty_append_glyph): New function.
17588 (produce_stretch_glyph): Static function and its prototype deleted.
17589
17590 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
17591 Add prototypes.
17592
175932011-08-29 Paul Eggert <eggert@cs.ucla.edu>
17594
17595 * image.c (parse_image_spec): Check for nonnegative, not for positive,
17596 when checking :margin (Bug#9390).
17597 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
17598 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
17599 so that the name doesn't mislead. All uses changed.
17600
176012011-08-28 Johan Bockgård <bojohan@gnu.org>
17602
17603 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
17604 set_tty_hooks.
17605
176062011-08-27 Eli Zaretskii <eliz@gnu.org>
17607
17608 * xdisp.c (move_it_to): Don't bail out early when reaching
17609 position beyond to_charpos, if we are scanning backwards.
17610 (move_it_vertically_backward): When DY == 0, make sure we get to
17611 the first character in the line after the newline.
17612
176132011-08-27 Paul Eggert <eggert@cs.ucla.edu>
17614
17615 * ccl.c: Improve and simplify overflow checking (Bug#9196).
17616 (ccl_driver): Do not generate an out-of-range pointer.
17617 (Fccl_execute_on_string): Remove unnecessary check for
17618 integer overflow, noted by Stefan Monnier in
17619 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
17620 Remove a FIXME that didn't need fixing.
17621 Simplify the newly-introduced buffer reallocation code.
17622
176232011-08-27 Juanma Barranquero <lekktu@gmail.com>
17624
17625 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
17626
176272011-08-26 Paul Eggert <eggert@cs.ucla.edu>
17628
17629 Integer and memory overflow issues (Bug#9196).
17630
17631 * doc.c (get_doc_string): Rework so that
17632 get_doc_string_buffer_size is the actual buffer size, rather than
17633 being 1 less than the actual buffer size; this makes xpalloc more
17634 convenient.
17635
17636 * image.c (x_allocate_bitmap_record, cache_image):
17637 * xselect.c (Fx_register_dnd_atom):
17638 Simplify previous changes by using xpalloc.
17639
17640 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
17641 since either will do and ptrdiff_t is convenient with xpalloc.
17642
17643 * charset.c (charset_table_size)
17644 (struct charset_sort_data.priority): Now ptrdiff_t.
17645 (charset_compare): Don't overflow if priorities differ greatly.
17646 (Fsort_charsets): Don't assume list length fits in int.
17647 Check for size-calculation overflow when allocating sort data.
17648 (syms_of_charset): Allocate an initial charset table that is
17649 just under 64 KiB, to avoid problems with glibc malloc and mmap.
17650
17651 * cmds.c (internal_self_insert): Check for size-calculation overflow.
17652
17653 * composite.h (struct composition.glyph_len): Now int, not unsigned.
17654 The actual value is always <= INT_MAX, and leaving it unsigned made
17655 overflow checking harder.
17656
17657 * dispextern.h (struct glyph_matrix.rows_allocated)
17658 (struct face_cache.size): Now ptrdiff_t, for convenience in use
17659 with xpalloc. The values are still always <= INT_MAX.
17660
17661 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
17662
17663 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
17664 (SAFE_NALLOCA): New macro.
17665
17666 * region-cache.c (struct boundary.pos, find_cache_boundary)
17667 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
17668 (set_cache_region, invalidate_region_cache)
17669 (revalidate_region_cache, know_region_cache, region_cache_forward)
17670 (region_cache_backward, pp_cache):
17671 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
17672 so that ptrdiff_t * can be passed to xpalloc.
17673 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
17674 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
17675 (pp_cache): Don't assume cache_len fits in int.
17676 * region-cache.h: Adjust extern decls to match.
17677
17678 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
17679 EMACS_INT, since either will do, for xpalloc.
17680
17681 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
17682 (xnmalloc, xnrealloc, xpalloc): New functions.
17683
17684 * bidi.c (bidi_shelve_header_size): New constant.
17685 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
17686 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
17687
17688 * bidi.c (bidi_cache_shrink):
17689 * buffer.c (overlays_at, overlays_in, record_overlay_string)
17690 (overlay_strings):
17691 Don't update size of array until after memory allocation succeeds,
17692 because xmalloc/xrealloc may not return.
17693 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
17694 now that we have proper integer overflow checking.
17695 (record_overlay_string, overlay_strings): Catch overflows when
17696 calculating size of overlay_str_buf.
17697
17698 * callproc.c (Fcall_process): Check for size overflow when
17699 calculating size of args2.
17700 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
17701 Normally we prefer signed values, but sticking with ptrdiff_t would
17702 require adding more-complicated checks.
17703
17704 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
17705 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
17706 Redo buffer-overflow calculations to avoid integer overflow.
17707 Add a FIXME comment where memory seems to be over-allocated.
17708
17709 * character.c (Fstring): Check for size-calculation overflow.
17710
17711 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
17712 unnecessary integer overflow. Check for size overflow.
17713 (encode_coding_object): Don't update size until xmalloc succeeds.
17714
17715 * composite.c (get_composition_id): Check for overflow in glyph
17716 length calculations.
17717
17718 Integer and memory overflow fixes for display code.
17719 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
17720 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
17721 (scrolling_window): Check for overflow in size calculations.
17722 (line_draw_cost, realloc_glyph_pool, add_row_entry):
17723 Don't assume glyph table len fits in int.
17724 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
17725 (row_table_size): Now ptrdiff_t, not int.
17726 (scrolling_window): Avoid overflow in size calculations.
17727 Don't update size until allocation succeeds.
17728 * fns.c (concat): Check for overflow in size calculations.
17729 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
17730 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
17731 (NEXT_ALMOST_PRIME_LIMIT): New constant.
17732
17733 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
17734 (get_doc_string): Check for size calculation overflow.
17735 Don't update size until allocation succeeds.
17736 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
17737 EMACS_INT, where ptrdiff_t will do.
17738 (Fsubstitute_command_keys): Check for string overflow.
17739
17740 * editfns.c (set_time_zone_rule): Don't assume environment length
17741 fits in int.
17742 (message_length): Now ptrdiff_t, not int.
17743 (Fmessage_box): Don't update size until allocation succeeds.
17744 Don't assume message length fits in int.
17745 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
17746
17747 * emacs.c (main): Do not reallocate argv, since there is a null at
17748 the end that can be overwritten, and this way there's no need to
17749 worry about size-calculation overflow.
17750 (sort_args): Check for size-calculation overflow.
17751
17752 * eval.c (init_eval_once, grow_specpdl): Don't update size until
17753 alloc succeeds.
17754 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
17755
17756 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
17757 (x_set_scroll_bar_width, x_figure_window_size):
17758 Check for integer overflow.
17759 (x_set_alpha): Do not assume XINT fits in int.
17760
17761 * frame.h (struct frame): Use int, not EMACS_INT, where int works.

17772 Check for size-calculation overflow.
17773 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
17774 do, as we prefer signed integers.

17781 * gtkutil.h: Change prototypes to match the above.
17782
17783 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
17784 are duplicate now that they've been promoted to lisp.h.
17785 (x_allocate_bitmap_record, x_alloc_image_color)
17786 (make_image_cache, cache_image, xpm_load):

17830 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
17831 for command line length. Do not attempt to address one before the
17832 beginning of an array, as that's not portable.

17834 * term.c (max_frame_lines): Remove; unused.
17835 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
17836 not int.
17837 (encode_terminal_code, calculate_costs): Check for size
17838 calculation overflow.
17839 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph

17861 (Finternal_make_lisp_face, cache_face):
17862 Check for size calculation overflow.
17863 (cache_face): Treat size calculation overflows as if they were

17866 * xfns.c (x_encode_text, x_set_name_internal)
17867 (Fx_change_window_property): Use ptrdiff_t, not int, to count

17873 Don't update size until alloc done.
17874
17875 * xrdb.c (get_environ_db): Don't assume path length fits in int,
17876 as sprintf is limited to int lengths.
17877
17878 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
17879 (X_LONG_MIN): New macros.
17880 Use them to make the following changes clearer.
17881 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
17882 This change doesn't affect the value now, but it may help remind
17883 future maintainers not to raise the value too much later.
17884 (SELECTION_QUANTUM): Remove, replacing with ...
17885 (selection_quantum): ... new function, which avoids overflow.
17886 All uses changed.
17887 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
17888 assumption that selection length fits in 'int'.

17894 (x_reply_selection_request, x_get_window_property)
17895 (receive_incremental_selection, x_property_data_to_lisp):
17896 Redo calculations to avoid overflow.
17897 (x_reply_selection_request): When sending hint, ceiling it at
17898 X_LONG_MAX rather than relying on wraparound overflow to send
17899 something.

17905 Don't store size until memory allocation succeeds.
17906 (x_get_window_property): Plug memory leak on memory exhaustion.
17907 Don't double-block input; malloc is safe here. Don't assume 2**34
17908 - 4 fits in unsigned long. Add an xassert to check
17909 XGetWindowProperty overflow. Be more careful about overflow
17910 calculations, and distinguish size from memory overflow better.
17911 (receive_incremental_selection): When tracing, don't assume
17912 unsigned int is less than INT_MAX.
17913 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
17914 harmful) conversions of unsigned short to int.
17915 (lisp_data_to_selection_data): Don't assume that integers
17916 in the range -65535 through -1 fit in an X unsigned short.
17917 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
17918 result parameters unless successful. Rely on cons_to_unsigned
17919 to report problems with elements; the old code wasn't right anyway.
17920 (x_check_property_data): Check for int overflow; we cannot use
17921 a wider type due to X limits.
17922 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
17923
17924 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

17954 * lisp.h (hash_lookup, hash_put):
17955 * minibuf.c (Ftest_completion):
17956 Use ptrdiff_t for hash table indexes, not int (which is too
17957 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
17958 32-bit --with-wide-int hosts).
17959
17960 * charset.c (Fdefine_charset_internal): Check for integer overflow.
17961 Add a FIXME comment about memory leaks.
17962 (syms_of_charset): Don't assume xmalloc returns.
17963
17964 Don't assume that stated character widths fit in int.

17966 * character.h (CHAR_WIDTH):
17967 * indent.c (MULTIBYTE_BYTES_WIDTH):
17968 Use sanitize_char_width to avoid undefined and/or bad behavior
17969 with outlandish widths.
17970 * character.h (sanitize_tab_width): Rename from sanitize_width,
17971 now that we have two such functions. All uses changed.
17972 (sanitize_char_width): New inline function.
17973
17974 Don't assume that tab-width fits in int.
17975 * character.h (sanitize_width): New inline function.
17976 (SANE_TAB_WIDTH): New macro.

17990 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
17991 (x_send_scroll_bar_event): Likewise. Check that the size does not
17992 exceed limits imposed by XClientMessageEvent, as well as the usual
17993 ptrdiff_t and size_t limits.
17994
17995 * keyboard.c: Overflow, signedness and related fixes.
17996 (make_lispy_movement): Use same integer type in forward decl
17997 that is used in the definition.
17998 (read_key_sequence, keyremap_step):
17999 Change bufsize argument back to int, undoing my 2011-03-30 change.
18000 We prefer signed types, and int is wide enough here.
18001 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
18002 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
18003 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
18004 length, not size_t. Use ptrdiff_t for index, not int.
18005 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
18006 possibility of integer overflow.
18007

18029 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
18030 (lookup_image): Remove unnecessary tests.
18031 (xbm_image_p): Locals are now of int, not EMACS_INT,
18032 since parse_image_check makes sure they fit into int.
18033 (png_load, gif_load, svg_load_image):
18034 Prefer int to unsigned where either will do.
18035 (tiff_handler): New function, combining the cores of the
18036 old tiff_error_handler and tiff_warning_handler.
18037 This function is rewritten to use vsnprintf and thereby avoid
18038 stack buffer overflows. It uses only the features of vsnprintf
18039 that are common to both POSIX and native Microsoft.
18040 (tiff_error_handler, tiff_warning_handler): Use it.
18041 (tiff_load, gif_load, imagemagick_load_image):
18042 Don't assume :index value fits in 'int'.
18043 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
18044 (imagemagick_load_image): Check that crop parameters fit into
18045 the integer types that MagickCropImage accepts. Don't assume
18046 Vimagemagick_render_type has a nonnegative value. Don't assume
18047 size_t fits in 'long'.
18048 (gs_load): Use printmax_t to print the widest integers possible.
18049 Check for integer overflow when computing image height and width.

18061 handle_single_display_spec, not just 1 or zero.
18062 (handle_single_display_spec): If the display spec is of the form
18063 `(space ...)', and specifies display in the text area, return 2
18064 rather than 1.
18065 (try_cursor_movement): Check for the need to scroll more
18066 accurately, and prefer exact match for point under bidi.
18067 Don't advance `row' beyond the last row of the window.
18068
18069 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
18070 into disp_prop; all users changed.
18071
18072 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
18073 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character

18085 buffers, return left-to-right.
18086 (set_cursor_from_row): Consider candidate row a win if its glyph
18087 represents a newline and point is on that newline. Fixes cursor
18088 positioning on the newline at EOL of R2L text within L2R
18089 paragraph, and vice versa.
18090 (try_cursor_movement): Check continued rows, in addition to
18091 continuation rows. Fixes unwarranted scroll when point enters a
18092 continued line of R2L text within an L2R paragraph, or vice versa.
18093 (cursor_row_p): Consider the case of point being equal to
18094 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
18095 from the end of a short line to the beginning of a continued line
18096 of R2L text within L2R paragraph.
18097 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
18098 composed characters.
18099
18100 * bidi.c (bidi_check_type): Use xassert.
18101 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p

18119
18120 * xdisp.c (redisplay_window): When computing centering_position,
18121 account for the height of the header line. (Bug#8874)
18122
18123 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
18124 instead of CHAR_TO_BYTE. Fixes a crash when a completion
18125 candidate is selected by the mouse, and that candidate has a
18126 composed character under the mouse.
18127
18128 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
18129 coordinates reported by pos-visible-in-window-p for a composed
18130 character in column zero.

18137
18138 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
18139 consider it a hit if to_charpos is anywhere in the range of the
18140 composed buffer positions.
18141
181422011-08-22 Chong Yidong <cyd@stupidchicken.com>
18143
18144 * image.c (gif_load): Don't assume that each subimage has the same
18145 dimensions as the base image. Handle disposal method that is

18169
18170 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
18171 members before the level stack, so they would be saved and
18172 restored when copying iterator state. Fixes incorrect reordering
18173 around TABs covered by display properties.
18174

18246
18247 * xdisp.c (move_it_in_display_line_to): Don't invoke
18248 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from

18259 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
18260 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
18261 the event loop. Get status from as_status (Bug#7276).
18262
18263 * nsterm.m (sendEvent): If event is NSApplicationDefined and
18264 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
18265 the event loop (Bug#7276).
18266
182672011-08-14 Andreas Schwab <schwab@linux-m68k.org>
18268

18300
18301 * xdisp.c (iterate_out_of_display_property): xassert that
18302 IT->position is set to within IT->object's boundaries. Break from
18303 the loop as soon as EOB is reached; avoids infloops in redisplay
18304 when IT->position is set up wrongly due to some bug.
18305 Set IT->current to match the bidi iterator unconditionally.
18306 (push_display_prop): Allow GET_FROM_STRING as IT->method on
18307 entry. Force push_it to save on the stack the current
18308 buffer/string position, to be restored by pop_it. Fix flags in
18309 the iterator structure wrt the object coming from a display
18310 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
18311 properties. (Bug#9284)
18312
183132011-08-09 Andreas Schwab <schwab@linux-m68k.org>

183252011-08-08 Eli Zaretskii <eliz@gnu.org>
18326
18327 * xdisp.c (forward_to_next_line_start): Allow to use the
18328 no-display-properties-and-no-overlays under bidi display.
18329 Set disp_pos in the bidi iterator to avoid searches for display
18330 properties and overlays.

18344
183452011-08-07 Juri Linkov <juri@jurta.org>
18346
18347 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
18348 to show the arg `TIME' instead of `TIMEVAL'.
18349
183502011-08-06 Eli Zaretskii <eliz@gnu.org>
18351
18352 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
18353 display property strides EOL and includes a newline, as in
18354 longlines-mode. (Bug#9254)
18355 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
18356 word-wrap under bidirectional display. (Bug#9224)
18357
18358 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
18359 is non-zero, even if the data buffer is NULL. Fixes a crash in
18360 vertical-motion with longlines-mode. (Bug#9254)

18370 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
18371 amount allocated this far in `bidi_cache_total_alloc'.
18372 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
18373 non-zero, only free the data buffer without restoring the cache
18374 contents. All callers changed.
18375
18376 * dispextern.h (bidi_unshelve_cache): Update prototype.
18377
18378 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
18379 (move_it_in_display_line, move_it_to)
18380 (move_it_vertically_backward, move_it_by_lines): Replace the call
18381 to xfree to an equivalent call to bidi_unshelve_cache.
18382 (move_it_in_display_line_to): Fix logic of returning
18383 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)

18386
18387 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that

18427 Fix slow cursor motion and scrolling in large buffers with
18428 selective display, like Org Mode buffers. (Bug#9218)
18429
18430 * dispextern.h (struct bidi_it): New member disp_prop_p.
18431
18432 * xdisp.c: Remove one-slot cache of display string positions.
18433 (compute_display_string_pos): Accept an additional argument
18434 DISP_PROP_P; callers changed. Scan at most 5K characters forward

18436 non-zero.
18437
18438 * bidi.c (bidi_fetch_char): Accept an additional argument
18439 DISP_PROP_P, and pass it to compute_display_string_pos.

18451
184522011-08-02 Kenichi Handa <handa@m17n.org>

18459
18460 * xdisp.c (forward_to_next_line_start): Accept additional argument

18474
18475 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).

184782011-07-28 Andreas Schwab <schwab@linux-m68k.org>
18479
18480 * print.c (print_object): Print empty symbol as ##.

18494
18495 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
18496 or scroll bar (Bug#8470).
18497
18498 * nsfont.m (nsfont_open): Remove assignment to voffset and

18501

18526
18527 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
18528 Without this fix, if a signal arrives just after memory fills up,
18529 'malloc' might be invoked reentrantly.
18530
18531 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
18532 In other words, assume that every image size is allowed, on non-X
18533 hosts. This assumption is probably wrong, but it lets Emacs compile.
18534
185352011-07-28 Andreas Schwab <schwab@linux-m68k.org>
18536
18537 * regex.c (re_iswctype): Convert return values to boolean.

18556 (bidi_cache_find_level_change, bidi_cache_ensure_space)
18557 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
18558 (bidi_find_other_level_edge):
18559 Use ptrdiff_t instead of EMACS_INT where either will do.
18560 This works better on 32-bit hosts configured --with-wide-int.
18561 (bidi_cache_ensure_space): Check for size-calculation overflow.
18562 Use % rather than repeated addition, for better worst-case speed.
18563 Don't set bidi_cache_size until after xrealloc returns, because it
18564 might not return.
18565 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
18566 (bidi_cache_ensure_space): Also check that the bidi cache size
18567 does not exceed that of the largest Lisp string or buffer. See Eli
18568 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
18569
18570 * alloc.c (__malloc_size_t): Remove.
18571 All uses replaced by size_t. See Andreas Schwab's note
18572 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
18573
18574 * image.c: Improve checking for integer overflow.
18575 (check_image_size): Assume that f is nonnull, since
18576 it is always nonnull in practice. This is one less thing to
18577 worry about when checking for integer overflow later.
18578 (x_check_image_size): New function, which checks for integer
18579 overflow issues inside X.
18580 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
18581 This removes the need for a memory_full check.
18582 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
18583 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
18584 (xbm_read_bitmap_data): Change locals back to 'int', since
18585 their values must fit in 'int'.
18586 (xpm_load_image, png_load, tiff_load):
18587 Invoke x_create_x_image_and_pixmap earlier,
18588 to avoid much needless work if the image is too large.
18589 (tiff_load): Treat overly large images as if
18590 x_create_x_image_and_pixmap failed, not as malloc failures.
18591 (gs_load): Use x_check_image_size.
18592
18593 * gtkutil.c: Omit integer casts.
18594 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
18595 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
18596
18597 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
18598
18599 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
18600 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
18601 would wrongly return t on a 64-bit host.
18602
18603 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
18604 The plain *_OVERFLOW macros run afoul of GCC bug 49705
18605 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
18606 and therefore cause GCC to emit a bogus diagnostic in some cases.
18607
18608 * image.c: Integer signedness and overflow and related fixes.
18609 This is not an exhaustive set of fixes, but it's time to
18610 record what I've got.
18611 (lookup_pixel_color, check_image_size): Remove redundant decls.
18612 (check_image_size): Don't assume that arbitrary EMACS_INT values
18613 fit in 'int', or that arbitrary 'double' values fit in 'int'.
18614 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
18615 (tiff_load, imagemagick_load_image):
18616 Check for overflow in size calculations.
18617 (x_create_x_image_and_pixmap): Remove unnecessary test for
18618 xmalloc returning NULL; that can't happen.
18619 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
18620 (xpm_color_bucket): Use better integer hashing function.
18621 (xpm_cache_color): Don't possibly over-allocate memory.
18622 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
18623 (gif_memory_source):
18624 Use ptrdiff_t, not int or size_t, to record sizes.
18625 (png_load): Don't assume values greater than 2**31 fit in 'int'.
18626 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
18627 either works, as we prefer signed integers.
18628 (tiff_read_from_memory, tiff_write_from_memory):
18629 Return tsize_t, not size_t, since that's what the TIFF API wants.
18630 (tiff_read_from_memory): Don't fail simply because the read would
18631 go past EOF; instead, return a short read.
18632 (tiff_load): Omit no-longer-needed casts.
18633 (Fimagemagick_types): Don't assume size fits into 'int'.
18634
18635 Improve hashing quality when configured --with-wide-int.
18636 * fns.c (hash_string): New function, taken from sxhash_string.
18637 Do not discard information about ASCII character case; this
18638 discarding is no longer needed.
18639 (sxhash-string): Use it. Change sig to match it. Caller changed.
18640 * lisp.h: Declare it.
18641 * lread.c (hash_string): Remove, since we now use fns.c's version.
18642 The fns.c version returns a wider integer if --with-wide-int is
18643 specified, so this should help the quality of the hashing a bit.
18644
18645 * emacs.c: Integer overflow minor fix.
18646 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
18647 Define only if GNU_LINUX.
18648 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
18649
18650 * dispnew.c: Integer signedness and overflow fixes.
18651 Remove unnecessary forward decls, that were a maintenance hassle.
18652 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
18653 All uses changed.
18654 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
18655 (scrolling_window): Use ptrdiff_t, not int, for byte count.
18656 (prepare_desired_row, line_draw_cost):
18657 Use int, not unsigned, where either works.
18658 (save_current_matrix, restore_current_matrix):
18659 Use ptrdiff_t, not size_t, where either works.
18660 (init_display): Check for overflow more accurately, and without
18661 relying on undefined behavior.
18662
18663 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
18664 Remove, replacing with the new symbols in lisp.h. All uses changed.
18665 * fileio.c (make_temp_name):
18666 * filelock.c (lock_file_1, lock_file):
18667 * xdisp.c (message_dolog):
18668 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
18669 Use pMd etc. instead.
18670 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
18671 replacing the pWIDE etc. symbols removed from editfns.c.
18672
18673 * keyboard.h (num_input_events): Now uintmax_t.
18674 This is (very slightly) less likely to mess up due to wraparound.
18675 All uses changed.
18676
18677 * buffer.c: Integer signedness fixes.
18678 (alloc_buffer_text, enlarge_buffer_text):
18679 Use ptrdiff_t rather than size_t when either will do, as we prefer
18680 signed integers.
18681
18682 * alloc.c: Integer signedness and overflow fixes.
18683 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
18684 (__malloc_size_t): Default to size_t, not to int.
18685 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
18686 (Fgarbage_collect, mark_object_loop_halt, mark_object):
18687 Prefer ptrdiff_t to size_t when either would do, as we prefer
18688 signed integers.
18689 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
18690 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
18691 Now const. Initialize with values that are in range even if char
18692 is signed.
18693 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
18694 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
18695 These functions do the right thing with sizes > 2**32.
18696 (check_depth): Now ptrdiff_t, not int.
18697 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
18698 Adjust to new way of storing sizes. Check for size overflow bugs
18699 in rest of code.
18700 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
18701 slightly wrong anyway, as it missed one instance of
18702 XMALLOC_OVERRUN_CHECK_OVERHEAD.
18703 (refill_memory_reserve): Omit needless cast to size_t.
18704 (mark_object_loop_halt): Mark as externally visible.
18705
18706 * xselect.c: Integer signedness and overflow fixes.
18707 (Fx_register_dnd_atom, x_handle_dnd_message):
18708 Use ptrdiff_t, not size_t, since we prefer signed.
18709 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
18710 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
18711 x_dnd_atoms_size and x_dnd_atoms_length.
18712
18713 * doprnt.c: Prefer signed to unsigned when either works.
18714 * eval.c (verror):
18715 * doprnt.c (doprnt):
18716 * lisp.h (doprnt):
18717 * xdisp.c (vmessage):
18718 Use ptrdiff_t, not size_t, when using or implementing doprnt,
18719 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
18720 prefer signed arithmetic to avoid comparison confusion.
18721 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
18722 but is a bit tricky.
18723
18724 Assume freestanding C89 headers, string.h, stdlib.h.
18725 * data.c, doprnt.c, floatfns.c, print.c:
18726 Include float.h unconditionally.
18727 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
18728 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
18729 * regex.c: Likewise for stddef.h, string.h.
18730 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
18731 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
18732 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
18733 (STDC_HEADERS): Remove obsolete defines.
18734 * sysdep.c: Include limits.h unconditionally.
18735
18736 Assume support for memcmp, memcpy, memmove, memset.
18737 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
18738 * regex.c (memcmp, memcpy):
18739 Remove; we assume C89 now.
18740
18741 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
18742 (__malloc_safe_bcopy): Remove; no longer needed.
18743
18744 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
18745 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
18746 well either way, and we prefer signed to unsigned.
18747
187482011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
18749
18750 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
18751 closes the connection while we're reading (bug#9182).
18752
187532011-07-25 Jan Djärv <jan.h.d@swipnet.se>
18754
18755 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
18756 are specified (Bug#9168).
18757
187582011-07-25 Paul Eggert <eggert@cs.ucla.edu>
18759
18760 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
18761 Found by GCC static checking and --with-wide-int on a 32-bit host.
18762
187632011-07-25 Eli Zaretskii <eliz@gnu.org>
18764
18765 * xdisp.c (compute_display_string_pos): Fix logic of caching
18766 previous display string position. Initialize cached_prev_pos to
18767 -1. Fixes slow-down at the beginning of a buffer.
18768
187692011-07-24 Eli Zaretskii <eliz@gnu.org>
18770
18771 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
18772 for attrs[LFACE_FONTSET_INDEX].
18773
187742011-07-23 Paul Eggert <eggert@cs.ucla.edu>
18775
18776 * xml.c (parse_region): Remove unused local
18777 that was recently introduced.
18778
187792011-07-23 Eli Zaretskii <eliz@gnu.org>
18780
18781 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
18782 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
18783
18784 * xdisp.c (move_it_in_display_line_to): Record the best matching
18785 position for TO_CHARPOS while scanning the line, and restore it on
18786 exit if none of the characters scanned was an exact match.
18787 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
18788 when exact match is impossible due to invisible text, and the
18789 lines are truncated.
18790
187912011-07-23 Jan Djärv <jan.h.d@swipnet.se>
18792
18793 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
18794 for OSX >= 10.7.
18795
187962011-07-22 Eli Zaretskii <eliz@gnu.org>
18797
18798 Fix a significant slow-down of cursor motion with C-n, C-p,
18799 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
18800 auto-repeat under bidi redisplay in fontified buffers.
18801 * xdisp.c (compute_stop_pos_backwards): New function.
18802 (next_element_from_buffer): Call compute_stop_pos_backwards to
18803 find a suitable prev_stop when we find ourselves before
18804 base_level_stop.
18805 (reseat): Don't look for prev_stop, as that could mean a very long
18806 run.
18807 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
18808 <cached_disp_overlay_modiff>: Cache for last found display string
18809 position.
18810 (compute_display_string_pos): Return the cached position if asked
18811 about the same buffer in the same area of character positions, and
18812 the buffer wasn't changed since the time the display string
18813 position was cached.
18814
188152011-07-22 Eli Zaretskii <eliz@gnu.org>
18816
18817 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
18818 is an integer, which is important for empty lines. (Bug#9149)
18819
188202011-07-22 Chong Yidong <cyd@stupidchicken.com>
18821
18822 * frame.c (Fmodify_frame_parameters): In tty case, update the
18823 default face if necessary (Bug#4238).
18824
188252011-07-21 Chong Yidong <cyd@stupidchicken.com>
18826
18827 * editfns.c (Fstring_to_char): No need to explain what a character
18828 is in the docstring (Bug#6576).
18829
188302011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18831
18832 * xml.c (parse_region): Make sure we always return a tree.
18833
188342011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
18835
18836 * xml.c (parse_region): If a document contains only comments,
18837 return that, too.
18838
188392011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18840
18841 * xml.c (make_dom): Return comments, too.
18842
188432011-07-19 Paul Eggert <eggert@cs.ucla.edu>
18844
18845 Port to OpenBSD.
18846 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
18847 and the surrounding thread.
18848 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
18849 rather than fgets, and retry after EINTR. Otherwise, 'emacs
18850 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
18851 timer goes off.
18852 * s/openbsd.h (BROKEN_SIGIO): Define.
18853 * unexelf.c (unexec) [__OpenBSD__]:
18854 Don't update the .mdebug section of the Alpha COFF symbol table.
18855
188562011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
18857
18858 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
18859 (bug#8460).
18860
188612011-07-18 Paul Eggert <eggert@cs.ucla.edu>
18862
18863 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
18864 This fixes some race conditions on the permissions of any newly
18865 created file.
18866
18867 * alloc.c (valid_pointer_p): Use pipe, not open.
18868 This fixes some permissions issues when debugging.
18869
18870 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
18871 If fchown fails to set both uid and gid, try to set just gid,
18872 as that is sometimes allowed. Adjust the file's mode to eliminate
18873 setuid or setgid bits that are inappropriate if fchown fails.
18874
188752011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
18876
18877 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
18878 to compare Lisp_Objects.
18879 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
18880 global_gnutls_log_level, don't mistake it for a Lisp_Object.
18881 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
18882
188832011-07-17 Andreas Schwab <schwab@linux-m68k.org>
18884
18885 * lread.c (read_integer): Unread even EOF character.
18886 (read1): Likewise. Properly record start position of symbol.
18887
18888 * lread.c (read1): Read `#:' as empty uninterned symbol if no
18889 symbol character follows.
18890
188912011-07-17 Paul Eggert <eggert@cs.ucla.edu>
18892
18893 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
18894 This works around a problem with the previous change to Fcopy_file.
18895 Recent glibc declares fchown with __attribute__((warn_unused_result)),
18896 and without this change, GCC might complain about discarding
18897 fchown's return value.
18898
188992011-07-16 Juanma Barranquero <lekktu@gmail.com>
18900
18901 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
18902
189032011-07-16 Paul Eggert <eggert@cs.ucla.edu>
18904
18905 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
18906
189072011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
18908
18909 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
18910 it's used from the C level.
18911
18912 * process.c: Use the same condition for POLL_FOR_INPUT in both
18913 keyboard.c and process.c (bug#1858).
18914
189152011-07-09 Lawrence Mitchell <wence@gmx.li>
18916
18917 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
18918 (Fgnutls_boot): Use it.
18919
189202011-07-15 Andreas Schwab <schwab@linux-m68k.org>
18921
18922 * doc.c (Fsubstitute_command_keys): Revert last change.
18923
189242011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
18925
18926 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
18927 quotes the next character, and doesn't affect other longer
18928 sequences (bug#8935).
18929
18930 * lread.c (syms_of_lread): Clarify that is isn't only
18931 `eval-buffer' and `eval-defun' that's affected by
18932 `lexical-binding' (bug#8460).
18933
189342011-07-15 Eli Zaretskii <eliz@gnu.org>
18935
18936 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
18937 bidi redisplay when a line includes both an image and is truncated.
18938
189392011-07-14 Paul Eggert <eggert@cs.ucla.edu>
18940
18941 Fix minor problems found by static checking.
18942 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
18943 (elsz): Now a signed constant, not a size_t var. We prefer signed
18944 types to unsigned, to avoid integer comparison confusion. Without
18945 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
18946 "cannot optimize loop, the loop counter may overflow", a symptom
18947 of the confusion.
18948 * indent.c (Fvertical_motion): Mark locals as initialized.
18949 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
18950

18995 the iterator is before prev_stop.
18996 (init_iterator): Initialize bidi_p from the default value of
18997 bidi-display-reordering, not from buffer-local value. Use the

19020 next_element_from_c_string.
19021 (tool_bar_lines_needed, redisplay_tool_bar)
19022 (display_menu_bar): Force left-to-right direction. Add a FIXME
19023 comment for making that be controlled by a user option.

19037 pushed the iterator stack, restore the internal state of the bidi
19038 iterator by calling bidi_pop_it same number of times.
19039 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
19040 and we are bidi-iterating, don't decrement the iterator position;
19041 instead, set the first_elt flag in the bidi iterator, to produce
19042 the same effect.

19060 iterator.
19061 (handle_single_display_spec, get_overlay_strings_1)
19062 (push_display_prop): Fix initialization of paragraph direction for
19063 string when that of the parent object is not yet determined.

19079 (move_it_in_display_line_to): If iterator ended up at
19080 EOL, but we never saw any buffer positions smaller than
19081 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
19082 motion in bidi-reordered lines.
19083 (move_it_in_display_line_to): Record prev_method and prev_pos
19084 immediately before the call to set_iterator_to_next. Fixes cursor
19085 motion in bidi-reordered lines with stretch glyphs and strings
19086 displayed in margins. (Bug#8133) (Bug#8867)
19087 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past

19513
19514 Random fixes. E.g., (random) never returned negative values.
19515 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
19516 subseconds part to the entropy, as that's a bit more random.
19517 Prefer signed to unsigned, since the signedness doesn't matter and
19518 in general we prefer signed. When given a limit, use a
19519 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
19520 latter isn't right if USE_2_TAGS_FOR_INTS.
19521 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
19522 not 0..VALMASK. Don't discard "excess" bits that random () returns.

19533
19534 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
19535 This is more efficient than Ffile_directory_p and avoids a minor race.
19536
195372011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
19538
19539 * buffer.c (Foverlay_put): Say what the return value is

19542 * fileio.c (barf_or_query_if_file_exists): Check first if the file
19543 is a directory before asking whether to use the file name
19544 (bug#7564).
19545 (barf_or_query_if_file_exists): Make the "File is a directory"
19546 error be more correct.
19547
19548 * fns.c (Frequire): Remove the mention of the .gz files, since
19549 that's installation-specific, but keep the mention of

19560 (syms_of_gnutls): Remove duplicate DEFSYM for
19561 Qgnutls_bootprop_verify_hostname_error, an error for
19562 Qgnutls_bootprop_verify_error (which is no longer used).
19563
19564 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
19565 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
19566 Also (re)move comments that are misplaced or no longer relevant.

19666
19667 * eval.c (struct backtrace): Simplify and port the data structure.
19668 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
19669 signed bit field, as this assumption is not portable and it makes
19670 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
19671 "char debug_on_exit : 1" as this is not portable either; instead,
19672 use the portable "unsigned int debug_on_exit : 1". Remove unused
19673 member evalargs. Remove obsolete comments about cc bombing out.
19674

19716 (sort_overlays, overlay_strings): When an overlay's clone number
19717 matches the window's clone number process the overlay even if
19718 the overlay's window property doesn't match the current window.
19719
19720 * window.c (Fwindow_vchild): Rename to Fwindow_top_child.

19756
19757 * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling
19758 bidi_at_paragraph_end, since fast_looking_at doesn't like to be
19759 called at ZV.
19760
197612011-06-26 Chong Yidong <cyd@stupidchicken.com>
19762
19763 * process.c (wait_reading_process_output): Bypass select if

19768
19769 Use gnulib's dup2 module instead of rolling our own.

19840
19841 * print.c (printchar, strout): Check for string overflow.
19842 (PRINTPREPARE, printchar, strout):
19843 Don't set size unless allocation succeeds.
19844
19845 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
19846 for sizes. Check for string overflow more accurately.
19847 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
19848
19849 * macros.c: Integer and buffer overflow fixes.
19850 * keyboard.h (struct keyboard.kbd_macro_bufsize):
19851 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

19856
19857 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
19858
19859 * lread.c: Integer overflow fixes.
19860 (read_integer): Radix is now EMACS_INT, not int,
19861 to improve quality of diagnostics for out-of-range radices.
19862 Calculate buffer size correctly for out-of-range radices.
19863 (read1): Check for integer overflow in radices, and in
19864 read-circle numbers.
19865 (read_escape): Avoid int overflow.
19866 (Fload, openp, read_buffer_size, read1)
19867 (substitute_object_recurse, read_vector, read_list, map_obarray):
19868 Use ptrdiff_t, not int, for sizes.

19887
198882011-06-22 Paul Eggert <eggert@cs.ucla.edu>
19889
19890 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
19891 The following patches are for when GLYPH_DEBUG && !XASSERT.
19892 * dispextern.h (trace_redisplay_p, dump_glyph_string):
19893 * dispnew.c (flush_stdout):
19894 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
19895 Mark as externally visible.
19896 * dispnew.c (check_window_matrix_pointers): Now static.
19897 * dispnew.c (window_to_frame_vpos):
19898 * xfns.c (unwind_create_frame):
19899 * xterm.c (x_check_font): Remove unused local.
19900 * scroll.c (CHECK_BOUNDS):
19901 * xfaces.c (cache_fache): Rename local to avoid shadowing.
19902 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
19903 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
19904 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
19905 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
19906 Now static.
19907 (debug_method_add): Use va_list and vsprintf rather than relying
19908 on undefined behavior with wrong number of arguments.
19909 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
19910 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
19911 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
19912 since we're not interested in debugging glyphs with old libraries.
19913 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
19914 GCC 4.6.0's static checking.
19915
199162011-06-22 Paul Eggert <eggert@cs.ucla.edu>
19917

19933 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
19934 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
19935 (.bitmaps_last, struct x_output.icon_bitmap):
19936 Use ptrdiff_t, not int, for bitmap indexes.
19937 (x_allocate_bitmap_record): Check for size overflow.
19938 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
19939
19940 Use ptrdiff_t, not int, for overlay counts.
19941 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
19942 * editfns.c (overlays_around, get_pos_property):
19943 * textprop.c (get_char_property_and_overlay):

19946 * buffer.c (OVERLAY_COUNT_MAX): New macro.
19947 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
19948 (Fnext_overlay_change, Fprevious_overlay_change)
19949 (mouse_face_overlay_overlaps, Foverlays_in):
19950 Use ptrdiff_t, not int, for sizes.
19951 (overlays_at, overlays_in): Check for size-calculation overflow.
19952
19953 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
19954
19955 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
19956 (x_session_initialize): Do not assume string length fits in int.
19957
19958 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
19959 This is unlikely, but can occur if DPI is outlandish.
19960
19961 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
19962 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
19963

19968
19969 * xfont.c (xfont_match): Avoid need for strlen.
19970
19971 * xfns.c: Don't assume strlen fits in int.
19972 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
19973
19974 * xdisp.c (message_log_check_duplicate): Return intmax_t,
19975 not unsigned long, as we prefer signed integers. All callers changed.
19976 Detect integer overflow in repeat count.
19977 (message_dolog): Don't assume print length fits in 39 bytes.
19978 (display_mode_element): Don't assume strlen fits in int.

19998
19999 * filelock.c: Fix some buffer overrun and integer overflow issues.
20000 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
20001 Reformulate so as not to need the command string.
20002 Invoke gzip -cd rather than gunzip, as it's more portable.
20003 (lock_info_type, lock_file_1, lock_file):
20004 Don't assume pid_t and time_t fit in unsigned long.
20005 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
20006 (current_lock_owner): Prefer signed type for sizes.
20007 Use memcpy, not strncpy, where memcpy is what is really wanted.
20008 Don't assume (via atoi) that time_t and pid_t fit in int.
20009 Check for time_t and/or pid_t out of range, e.g., via a network share.
20010 Don't alloca where an auto var works fine.
20011
20012 * fileio.c: Fix some integer overflow issues.
20013 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
20014 Don't assume string length fits in int.
20015 (directory_file_name): Don't assume string length fits in long.
20016 (make_temp_name): Don't assume pid fits in int, or that its print
20017 length is less than 20.
20018
20019 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
20020
20021 * coding.c (make_subsidiaries): Don't assume string length fits in int.
20022
20023 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
20024
20025 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
20026 We prefer signed integers, even for size calculations.
20027
20028 * emacs.c: Don't assume string length fits in 'int'.
20029 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
20030 (main): Don't invoke strlen when not needed.
20031
20032 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.

20037 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
20038
20039 * lread.c (invalid_syntax): Omit length argument.
20040 All uses changed. This doesn't fix a bug, but it simplifies the
20041 code away from its former Hollerith-constant appearance, and it's
20042 one less 'int' to worry about when looking at integer-overflow issues.
20043 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
20044
20045 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
20046 This didn't break anything, but it didn't help either.
20047 It's confusing to put a bogus integer in a place where the actual
20048 value does not matter.
20049 (LIST_END_P): Remove unused macro and its bogus comment.
20050 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
20051
20052 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
20053 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
20054 implementation.
20055 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
20056 We prefer signed types, and the value cannot exceed the EMACS_INT
20057 range anyway (because otherwise the length would not be representable).
20058 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
20059 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
20060 This avoids a GCC warning when WIDE_EMACS_INT.
20061
20062 * indent.c (sane_tab_width): New function.
20063 (current_column, scan_for_column, Findent_to, position_indentation)
20064 (compute_motion): Use it. This is just for clarity.
20065 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
20066
20067 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
20068
20069 * lisp.h (lint_assume): New macro.
20070 * composite.c (composition_gstring_put_cache):
20071 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
20072
20073 * editfns.c, insdel.c:
20074 Omit unnecessary forward decls, to simplify future changes.
20075
20076 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
20077
20078 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
20079
20080 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
20081 Use much-faster test for byte-length change.
20082 Don't assume string byte-length fits in 'int'.
20083 Check that character arg fits in 'int'.
20084 (mapcar1): Declare byte as byte, for clarity.
20085
20086 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
20087
20088 * fns.c (concat): Catch string overflow earlier.
20089 Do not rely on integer wraparound.
20090
20091 * dispextern.h (struct it.overlay_strings_charpos)
20092 (struct it.selective): Now EMACS_INT, not int.
20093 * xdisp.c (forward_to_next_line_start)
20094 (back_to_previous_visible_line_start)
20095 (reseat_at_next_visible_line_start, next_element_from_buffer):
20096 Don't arbitrarily truncate the value of 'selective' to int.
20097
20098 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
20099
20100 * composite.c: Don't truncate sizes to 'int'.
20101 (composition_gstring_p, composition_reseat_it)
20102 (composition_adjust_point): Use EMACS_INT, not int.
20103 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
20104 not EMACS_UINT, for indexes.
20105
20106 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
20107
20108 * buffer.c: Include <verify.h>.
20109 (struct sortvec.priority, struct sortstr.priority):
20110 Now EMACS_INT, not int.
20111 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
20112 (struct sortstr.size, record_overlay_string)
20113 (struct sortstrlist.size, struct sortlist.used):
20114 Don't truncate size to int.
20115 (record_overlay_string): Check for size-calculation overflow.
20116 (init_buffer_once): Check at compile-time, not run-time.
20117

20119
20120 Don't leak an XBM-image-sized buffer
20121 * image.c (xbm_load): Free the image buffer after using it.
20122
201232011-06-21 Paul Eggert <eggert@cs.ucla.edu>
20124
20125 Port to Sun C.
20126 * composite.c (find_automatic_composition): Omit needless 'return 0;'
20127 that Sun C diagnosed.
20128 * fns.c (secure_hash): Fix pointer signedness issue.
20129 * intervals.c (static_offset_intervals): New function.
20130 (offset_intervals): Use it.
20131
201322011-06-21 Leo Liu <sdl.web@gmail.com>
20133
20134 * deps.mk (fns.o):
20135 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
20136 sha512.h.
20137
20138 * fns.c (secure_hash): Rename from crypto_hash_function and change
20139 the first arg to accept symbols.
20140 (Fsecure_hash): New primitive.
20141 (syms_of_fns): New symbols.
20142
201432011-06-20 Deniz Dogan <deniz@dogan.se>
20144
20145 * process.c (Fset_process_buffer): Clarify return value in
20146 docstring.
20147
201482011-06-18 Chong Yidong <cyd@stupidchicken.com>
20149
20150 * dispnew.c (add_window_display_history): Use BVAR.
20151
20152 * xdisp.c (debug_method_add): Use BVAR.
20153 (check_window_end, dump_glyph_matrix, dump_glyph)
20154 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
20155
20156 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
20157 Likewise.
20158
20159 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
20160 check till after the cache is created in init_frame_faces.
20161
201622011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
20163
20164 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
20165
201662011-06-16 Paul Eggert <eggert@cs.ucla.edu>
20167
20168 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
20169 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
20170 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
20171
20172 Improve buffer-overflow checking (Bug#8873).
20173 * fileio.c (Finsert_file_contents):
20174 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
20175 Remove the old (too-loose) buffer overflow checks.
20176 They weren't needed, since make_gap checks for buffer overflow.
20177 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
20178 The old code merely checked for Emacs fixnum overflow, and relied
20179 on undefined (wraparound) behavior. The new code avoids undefined
20180 behavior, and also checks for ptrdiff_t and/or size_t overflow.
20181
20182 * editfns.c (Finsert_char): Don't dump core with very negative counts.
20183 Tune. Don't use wider integers than needed. Don't use alloca.
20184 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
20185
20186 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
20187
20188 * insdel.c, lisp.h (buffer_overflow): New function.
20189 (insert_from_buffer_1, replace_range, replace_range_2):
20190 * insdel.c (make_gap_larger):
20191 * editfns.c (Finsert_char):
20192 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
20193
20194 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
20195
201962011-06-15 Paul Eggert <eggert@cs.ucla.edu>
20197
20198 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
20199
20200 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
20201 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
20202
20203 * fileio.c: Don't assume EMACS_INT fits in off_t.
20204 (emacs_lseek): New static function.
20205 (Finsert_file_contents, Fwrite_region): Use it.
20206 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
20207
20208 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
20209
20210 * fns.c: Don't overflow int when computing a list length.
20211 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
20212 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
20213 truncation on 64-bit hosts. Check for QUIT every
20214 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
20215 faster and is responsive enough.
20216 (Flength): Report an error instead of overflowing an integer.
20217 (Fsafe_length): Return a float if the value is not representable
20218 as a fixnum. This shouldn't happen except in contrived situations.
20219 (Fnthcdr, Fsort): Don't assume list length fits in int.
20220 (Fcopy_sequence): Don't assume vector length fits in int.
20221
20222 * alloc.c: Check that resized vectors' lengths fit in fixnums.
20223 (header_size, word_size): New constants.
20224 (allocate_vectorlike): Don't check size overflow here.
20225 (allocate_vector): Check it here instead, since this is the only
20226 caller of allocate_vectorlike that could cause overflow.
20227 Check that the new vector's length is representable as a fixnum.
20228
20229 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
20230 The previous code was bogus. For example, next_almost_prime (32)
20231 returned 39, which is undesirable as it is a multiple of 3; and
20232 next_almost_prime (24) returned 25, which is a multiple of 5 so
20233 why was the code bothering to check for multiples of 7?
20234
20235 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
20236
20237 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
20238
20239 Variadic C functions now count arguments with ptrdiff_t.
20240 This partly undoes my 2011-03-30 change, which replaced int with size_t.
20241 Back then I didn't know that the Emacs coding style prefers signed int.
20242 Also, in the meantime I found a few more instances where arguments
20243 were being counted with int, which may truncate counts on 64-bit
20244 machines, or EMACS_INT, which may be unnecessarily wide.
20245 * lisp.h (struct Lisp_Subr.function.aMANY)
20246 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
20247 Arg counts are now ptrdiff_t, not size_t.
20248 All variadic functions and their callers changed accordingly.
20249 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
20250 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
20251 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
20252 * callint.c (Fcall_interactively): Check arg count for overflow,
20253 to avoid potential buffer overrun. Use signed char, not 'int',
20254 for 'varies' array, so that we needn't bother to check its size
20255 calculation for overflow.
20256 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
20257 * eval.c (apply_lambda):
20258 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
20259 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
20260 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
20261
20262 * callint.c (Fcall_interactively): Don't use index var as event count.
20263
20264 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
20265 * mem-limits.h (SIZE): Remove; no longer used.
20266
20267 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
20268
20269 Remove unnecessary casts.
20270 * xterm.c (x_term_init):
20271 * xfns.c (x_set_border_pixel):
20272 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
20273 These aren't needed now that we assume ANSI C.
20274
20275 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
20276 It's more likely to cause problems (due to unsigned overflow)
20277 than to cure them.
20278
20279 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
20280
20281 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
20282
20283 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
20284
20285 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
20286
20287 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
20288
20289 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
20290
20291 GLYPH_CODE_FACE returns EMACS_INT, not int.
20292 * dispextern.h (merge_faces):
20293 * xfaces.c (merge_faces):
20294 * xdisp.c (get_next_display_element, next_element_from_display_vector):
20295 Don't assume EMACS_INT fits in int.
20296
20297 * character.h (CHAR_VALID_P): Remove unused parameter.
20298 * fontset.c, lisp.h, xdisp.c: All uses changed.
20299
20300 * editfns.c (Ftranslate_region_internal): Omit redundant test.
20301
20302 * fns.c (concat): Minor tuning based on overflow analysis.
20303 This doesn't fix any bugs. Use int to hold character, instead
20304 of constantly refetching from Emacs object. Use XFASTINT, not
20305 XINT, for value known to be a character. Don't bother comparing
20306 a single byte to 0400, as it's always less.
20307
20308 * floatfns.c (Fexpt):
20309 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
20310
20311 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
20312 for characters.
20313
20314 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
20315
20316 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
20317 Without this fix, on a 64-bit host (aset S 0 4294967386) would
20318 incorrectly succeed when S was a string, because 4294967386 was
20319 truncated before it was used.
20320
20321 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
20322 Otherwise, an out-of-range integer could cause undefined behavior
20323 on a 64-bit host.
20324
20325 * composite.c: Use int, not EMACS_INT, for characters.
20326 (fill_gstring_body, composition_compute_stop_pos): Use int, not
20327 EMACS_INT, for values that are known to be in character range.
20328 This doesn't fix any bugs but is the usual style inside Emacs and
20329 may generate better code on 32-bit machines.
20330
20331 Make sure a 64-bit char is never passed to ENCODE_CHAR.
20332 This is for reasons similar to the recent CHAR_STRING fix.
20333 * charset.c (Fencode_char): Check that character arg is actually
20334 a character. Pass an int to ENCODE_CHAR.
20335 * charset.h (ENCODE_CHAR): Verify that the character argument is no
20336 wider than 'int', as a compile-time check to prevent future regressions
20337 in this area.
20338
20339 * character.c (char_string): Remove unnecessary casts.
20340
20341 Make sure a 64-bit char is never passed to CHAR_STRING.
20342 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
20343 by silently ignoring the top 32 bits, allowing some values
20344 that were far too large to be valid characters.
20345 * character.h: Include <verify.h>.
20346 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
20347 arguments are no wider than unsigned, as a compile-time check
20348 to prevent future regressions in this area.
20349 * data.c (Faset):
20350 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
20351 (Fsubst_char_in_region):
20352 * fns.c (concat):
20353 * xdisp.c (decode_mode_spec_coding):
20354 Adjust to CHAR_STRING's new requirement.
20355 * editfns.c (Finsert_char, Fsubst_char_in_region):
20356 * fns.c (concat): Check that character args are actually
20357 characters. Without this test, these functions did the wrong
20358 thing with wildly out-of-range values on 64-bit hosts.
20359
20360 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
20361 These casts should not be needed on 32-bit hosts, either.
20362 * keyboard.c (read_char):
20363 * lread.c (Fload): Remove casts to unsigned.
20364
20365 * lisp.h (UNSIGNED_CMP): New macro.
20366 This fixes comparison bugs on 64-bit hosts.
20367 (ASCII_CHAR_P): Use it.
20368 * casefiddle.c (casify_object):
20369 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
20370 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
20371 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
20372 * dispextern.h (FACE_FROM_ID):
20373 * keyboard.c (read_char): Use UNSIGNED_CMP.
20374
20375 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
20376 not to EMACS_INT, to avoid GCC warning.
20377
20378 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
20379
20380 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
20381 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
20382 isn't needed on 32-bit machines.
20383
20384 * buffer.c (Fgenerate_new_buffer_name):
20385 Use EMACS_INT for count, not int.
20386 (advance_to_char_boundary): Return EMACS_INT, not int.
20387
20388 * data.c (Qcompiled_function): Now static.
20389
20390 * window.c (window_body_lines): Now static.
20391
20392 * image.c (gif_load): Rename local to avoid shadowing.
20393
20394 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
20395 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
20396 * alloc.c (make_save_value): Integer argument is now of type
20397 ptrdiff_t, not int.
20398 (mark_object): Use ptrdiff_t, not int.
20399 * lisp.h (pD): New macro.
20400 * print.c (print_object): Use it.
20401
20402 * alloc.c: Use EMACS_INT, not int, to count objects.
20403 (total_conses, total_markers, total_symbols, total_vector_size)
20404 (total_free_conses, total_free_markers, total_free_symbols)
20405 (total_free_floats, total_floats, total_free_intervals)
20406 (total_intervals, total_strings, total_free_strings):
20407 Now EMACS_INT, not int. All uses changed.
20408 (Fgarbage_collect): Compute overall total using a double, so that
20409 integer overflow is less likely to be a problem. Check for overflow
20410 when converting back to an integer.
20411 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
20412 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
20413 These were 'int' variables that could overflow on 64-bit hosts;
20414 they were never used, so remove them instead of repairing them.
20415 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
20416 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
20417 Previously, this ceilinged at INT_MAX, but that doesn't work on
20418 64-bit machines.
20419 (allocate_pseudovector): Don't use EMACS_INT when int would do.
20420
20421 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
20422 (allocate_vectorlike): Check for ptrdiff_t overflow.
20423 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
20424 when a (possibly-narrower) signed value would do just as well.
20425 We prefer using signed arithmetic, to avoid comparison confusion.
20426
20427 * alloc.c: Catch some string size overflows that we were missing.
20428 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
20429 for convenience in STRING_BYTES_MAX.
20430 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
20431 The definition here is exact; the one in lisp.h was approximate.
20432 (allocate_string_data): Check for string overflow. This catches
20433 some instances we weren't catching before. Also, it catches
20434 size_t overflow on (unusual) hosts where SIZE_MAX <= min
20435 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
20436 and ptrdiff_t and EMACS_INT are both 64 bits.
20437
20438 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
20439 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
20440 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
20441
20442 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
20443
20444 * alloc.c (Fmake_string): Check for out-of-range init.
20445
204462011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
20447
20448 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
20449
204502011-06-14 Jan Djärv <jan.h.d@swipnet.se>
20451
20452 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
20453 xg_get_default_scrollbar_width.
20454
20455 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
20456 (int_gtk_range_get_value): Move to the scroll bar part of the file.
20457 (style_changed_cb): Call update_theme_scrollbar_width and call
20458 x_set_scroll_bar_default_width and xg_frame_set_char_size for
20459 all frames (Bug#8505).
20460 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
20461 Call gtk_window_set_resizable if HAVE_GTK3.
20462 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
20463 and height if HAVE_GTK3 (Bug#8505).
20464 (scroll_bar_width_for_theme): New variable.
20465 (update_theme_scrollbar_width): New function.
20466 (xg_get_default_scrollbar_width): Move code to
20467 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
20468 (xg_initialize): Call update_theme_scrollbar_width.
20469
20470 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
20471
20472 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
20473
204742011-06-12 Martin Rudalics <rudalics@gmx.at>
20475
20476 * frame.c (make_frame): Call other_buffer_safely instead of
20477 other_buffer.
20478
20479 * window.c (temp_output_buffer_show): Call display_buffer with
20480 second argument Vtemp_buffer_show_specifiers and reset latter
20481 immediately after the call.
20482 (Vtemp_buffer_show_specifiers): New variable.
20483 (auto_window_vscroll_p, next_screen_context_lines)
20484 (Vscroll_preserve_screen_position): Remove leading asterisks from
20485 doc-strings.
20486
204872011-06-12 Paul Eggert <eggert@cs.ucla.edu>
20488
20489 Fix minor problems found by GCC 4.6.0 static checking.
20490 * buffer.c (Qclone_number): Remove for now, as it's unused.
20491 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
20492 (record_buffer): Remove unused local.
20493 * frame.c (other_visible_frames, frame_buffer_list): Now static.
20494 (set_frame_buffer_list): Remove; unused.
20495 * frame.h (other_visible_frames): Remove decl.
20496 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
20497 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
20498 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
20499 if HAVE_GPM.
20500 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
20501 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
20502 Define only if HAVE_GPM.
20503 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
20504 (update_hints_inhibit): Remove; never set. All uses removed.
20505 * widgetprv.h (emacsFrameClassRec): Remove decl.
20506 * window.c (delete_deletable_window): Now returns void, since it
20507 wasn't returning anything.
20508 (compare_window_configurations): Remove unused locals.
20509 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
20510 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
20511 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
20512 the same widths as pointers. This follows up on the 2011-05-06 patch.

20934 or arbitrary window as argument. Update doc-strings.
20935 (Fminibuffer_window): Move up in code.
20936 (Fwindow_minibuffer_p): Move up in code and simplify.
20937 (Fset_frame_selected_window): Move here from frame.c.

20940 code. Minor doc-string fixes.
20941
209422011-06-06 Paul Eggert <eggert@cs.ucla.edu>
20943
20944 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
20945 Do not assume that spare memory exists; that assumption is valid
20946 only if SYSTEM_MALLOC.
20947 (LARGE_REQUEST): New macro, so that the issue of large requests
20948 is separated from the issue of spare memory.
20949

20983 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
20984
209852011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
20986
20987 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
20988
209892011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20990
20991 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
20992 in the current matrix if keep_current_p is non-zero.
20993
209942011-06-04 Eli Zaretskii <eliz@gnu.org>
20995
20996 * bidi.c (bidi_level_of_next_char): Fix last change.
20997
209982011-06-03 Eli Zaretskii <eliz@gnu.org>
20999
21000 Support bidi reordering of text covered by display properties.
21001
21002 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
21003 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
21004 (bidi_cache_search, bidi_cache_iterator_state)
21005 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
21006 (bidi_level_of_next_char, bidi_move_to_visually_next):
21007 Support character positions inside a run of characters covered by a
21008 display string.
21009 (bidi_paragraph_init, bidi_resolve_explicit_1)
21010 (bidi_level_of_next_char): Call bidi_fetch_char and
21011 bidi_fetch_char_advance instead of FETCH_CHAR and
21012 FETCH_CHAR_ADVANCE.
21013 (bidi_init_it): Initialize new members.
21014 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
21015 definitions.
21016 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
21017 instead of using explicit *_CHAR codes.
21018 (bidi_resolve_explicit, bidi_resolve_weak):
21019 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
21020 bidirectional text is supported only in multibyte buffers.
21021 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
21022 it to initialize the frame_window_p member of struct bidi_it.
21023 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
21024 (bidi_resolve_explicit, bidi_resolve_weak)

21026 bidi_it->nchars is non-positive.
21027 (bidi_level_of_next_char): Don't try to lookup the cache for the
21028 next/previous character if nothing is cached there yet, or if we
21029 were just reseat()'ed to a new position.
21030
21031 * xdisp.c (set_cursor_from_row): Set start and stop points
21032 according to the row's direction when priming the loop that looks
21033 for the glyph on which to display cursor.
21034 (single_display_spec_intangible_p): Function deleted.
21035 (display_prop_intangible_p): Reimplement to call
21036 handle_display_spec instead of single_display_spec_intangible_p.
21037 Accept 3 additional arguments needed by handle_display_spec.
21038 This fixes incorrect cursor motion across display property with complex
21039 values: lists, `(when COND...)' forms, etc.
21040 (single_display_spec_string_p): Support property values that are
21041 lists with the argument STRING its top-level element.
21042 (display_prop_string_p): Fix the condition for processing a
21043 property that is a list to be consistent with handle_display_spec.
21044 (handle_display_spec): New function, refactored from the
21045 last portion of handle_display_prop.
21046 (compute_display_string_pos): Accept additional argument
21047 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
21048 value of a `display' property is a "replacing spec".
21049 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
21050 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
21051 the display property, but just return a value indicating whether
21052 the display property will replace the characters it covers.
21053 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
21054 frame_window_p members of struct bidi_it.
21055 (compute_display_string_pos, compute_display_string_end):
21056 New functions.

21060
21061 * keyboard.c (adjust_point_for_property): Adjust the call to
21062 display_prop_intangible_p to its new signature.
21063
21064 * dispextern.h (struct bidi_it): New member frame_window_p.
21065 (bidi_init_it): Update prototypes.

21067 (compute_display_string_pos, compute_display_string_end):
21068 Declare prototypes.

21076 * lisp.h: Change signatures accordingly.
21077 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
21078 All callers changed. (Bug#8762)
21079
21080 * gnutls.c: Use Emacs's memory allocators.
21081 Without this change, the gnutls library would invoke malloc etc.
21082 directly, which causes problems on non-SYNC_INPUT hosts, and which
21083 runs afoul of improving memory_full behavior. (Bug#8761)
21084 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
21085 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
21086 xfree instead of the default malloc, realloc, free.
21087 (Fgnutls_boot): No need to check for memory allocation failure,
21088 since xmalloc does that for us.
21089
21090 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
21091 * category.c (hash_get_category_set):

21099 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
21100 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
21101 (hashfn_equal, hashfn_user_defined, make_hash_table)

21103 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
21104 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
21105 (Fsxhash, Fgethash, Fputhash, Fmaphash):
21106 * image.c (make_image, search_image_cache, lookup_image)
21107 (xpm_put_color_table_h):
21108 * lisp.h (struct Lisp_Hash_Table):
21109 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
21110 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
21111 for hashes and hash indexes, instead of 'unsigned' and 'int'.
21112 * alloc.c (allocate_vectorlike):
21113 Check for overflow in vector size calculations.
21114 * ccl.c (ccl_driver):
21115 Check for overflow when converting EMACS_INT to int.
21116 * fns.c, image.c: Remove unnecessary static decls that would otherwise
21117 need to be updated by these changes.
21118 * fns.c (make_hash_table, maybe_resize_hash_table):
21119 Check for integer overflow with large hash tables.
21120 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
21121 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
21122 (SXHASH_REDUCE): New macro.
21123 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
21124 Use it instead of discarding useful hash info with large hash values.
21125 (sxhash_float): New function.
21126 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
21127 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
21128 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
21129 Rewrite to use FIXNUM_BITS, as this simplifies things.
21130 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
21131 Adjust signatures to match updated version of code.
21132 (consing_since_gc): Now EMACS_INT, since a single hash table can
21133 use more than INT_MAX bytes.
21134
211352011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
21136
21137 Make it possible to build with GCC-4.6+ -O2 -flto.
21138
21139 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
21140
211412011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
21142
21143 * minibuf.c (get_minibuffer, read_minibuf_unwind):

21145
211462011-05-31 Juanma Barranquero <lekktu@gmail.com>
21147
21148 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
21149 Update dependencies.
21150
211512011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
21152
21153 * data.c (init_data): Remove code for UTS, this system is not
21154 supported anymore.
21155
211562011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
21157
21158 Don't force ./temacs to start in terminal mode.
21159
21160 * frame.c (make_initial_frame): Initialize faces in all cases, not
21161 only when CANNOT_DUMP is defined.
21162 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
21163
211642011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
21165
21166 * dispnew.c (add_window_display_history): Use const for the string
21167 pointer. Remove declaration, not needed.
21168
211692011-05-31 Paul Eggert <eggert@cs.ucla.edu>
21170
21171 Use 'inline', not 'INLINE'.
21172 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
21173 * alloc.c, fontset.c (INLINE): Remove.
21174 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
21175 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
21176 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
21177 * gmalloc.c (register_heapinfo): Use inline unconditionally.
21178 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
21179
211802011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
21181
21182 Make it possible to run ./temacs.
21183
21184 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
21185 syms_of_callproc does the same thing. Remove test for
21186 "initialized", do it in the caller.
21187 * emacs.c (main): Avoid calling set_initial_environment when dumping.
21188
211892011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
21190
21191 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
21192 (read_minibuf): Use get_minibuffer.
21193 (syms_of_minibuf): Use DEFSYM.
21194 (Qmetadata): New var.
21195 * data.c (Qbuffer): Don't make it static.
21196 (syms_of_data): Use DEFSYM.
21197
211982011-05-31 Paul Eggert <eggert@cs.ucla.edu>
21199
21200 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
21201 (CCL_CODE_MIN): New macro.
21202
212032011-05-30 Paul Eggert <eggert@cs.ucla.edu>
21204
21205 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
21206
21207 * eval.c (Qdebug): Now static.
21208 * lisp.h (Qdebug): Remove decl. This reverts a part of the
21209 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
21210 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
21211
212122011-05-29 Chong Yidong <cyd@stupidchicken.com>
21213
21214 * image.c: Various fixes to ImageMagick code comments.
21215 (Fimagemagick_types): Doc fix.
21216
212172011-05-29 Paul Eggert <eggert@cs.ucla.edu>
21218
21219 Minor fixes prompted by GCC 4.6.0 warnings.
21220
21221 * xselect.c (converted_selections, conversion_fail_tag): Now static.
21222
21223 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
21224 (x_clipboard_manager_save_all): Move extern decl to ...
21225 * xterm.h: ... here, so that it can be checked for consistency.
21226
212272011-05-29 Chong Yidong <cyd@stupidchicken.com>
21228
21229 * xselect.c (x_clipboard_manager_save_frame)
21230 (x_clipboard_manager_save_all): New functions.
21231 (Fx_clipboard_manager_save): Lisp function deleted.
21232
21233 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
21234 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
21235

21241 exiting (Bug#8239).
21242
212432011-05-28 Jim Meyering <meyering@redhat.com>
21244
21245 Avoid a sign-extension bug in crypto_hash_function.
21246 * fns.c (to_uchar): Define.
21247 (crypto_hash_function): Use it to convert some newly-signed
21248 variables to unsigned, to avoid sign-extension bugs. For example,
21249 without this change, (md5 "truc") would evaluate to
21250 45723a2aff78ff4fff7fff1114760e62 rather than the expected
21251 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
21252 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
21253
212542011-05-27 Paul Eggert <eggert@cs.ucla.edu>
21255
21256 Integer overflow fixes.
21257
21258 * dbusbind.c: Serial number integer overflow fixes.
21259 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
21260 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
21261 to hold a serial number that is too large for a fixnum.
21262 (Fdbus_method_return_internal, Fdbus_method_error_internal):
21263 Check for serial numbers out of range. Decode any serial number
21264 that was so large that it became a float. (Bug#8722)
21265
21266 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
21267 (Fdbus_call_method, Fdbus_call_method_asynchronously):
21268 Use XFASTINT rather than XUINT when numbers are nonnegative.
21269 (xd_append_arg, Fdbus_method_return_internal):
21270 (Fdbus_method_error_internal): Likewise. Also, for unsigned
21271 arguments, check that Lisp number is nonnegative, rather than
21272 silently wrapping negative numbers around. (Bug#8722)
21273 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
21274 (Bug#8722)
21275
21276 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
21277
21278 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
21279
21280 ccl: Add integer overflow checks.
21281 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
21282 (IN_INT_RANGE): New macros.
21283 (ccl_driver): Use them to check for integer overflow when
21284 decoding a CCL program. Many of the new checks are whether XINT (x)
21285 fits in int; it doesn't always, on 64-bit hosts. The new version
21286 doesn't catch all possible integer overflows, but it's an
21287 improvement. (Bug#8719)
21288
21289 * alloc.c (make_event_array): Use XINT, not XUINT.
21290 There's no need for unsigned here.
21291
21292 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
21293 This follows up to the 2011-05-06 change that substituted uintptr_t
21294 for EMACS_INT. This case wasn't caught back then.
21295
21296 Rework Fformat to avoid integer overflow issues.
21297 * editfns.c: Include <float.h> unconditionally, as it's everywhere
21298 now (part of C89). Include <verify.h>.
21299 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
21300 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
21301 (Fformat): Avoid the prepass trying to compute sizes; it was only
21302 approximate and thus did not catch overflow reliably. Instead, walk
21303 through the format just once, formatting and computing sizes as we go,
21304 checking for integer overflow at every step, and allocating a larger
21305 buffer as needed. Keep track separately whether the format is
21306 multibyte. Keep only the most-recently calculated precision, rather
21307 than them all. Record whether each argument has been converted to
21308 string. Use EMACS_INT, not int, for byte and char and arg counts.
21309 Support field widths and precisions larger than INT_MAX. Avoid
21310 sprintf's undefined behavior with conversion specifications such as %#d
21311 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
21312 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
21313 formatting out-of-range floating point numbers with int
21314 formats. (Bug#8668)
21315
21316 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
21317
21318 * data.c: Avoid integer truncation in expressions involving floats.
21319 * data.c: Include <intprops.h>.
21320 (arith_driver): When there's an integer overflow in an expression
21321 involving floating point, convert the integers to floating point
21322 so that the resulting value does not suffer from catastrophic
21323 integer truncation. For example, on a 64-bit host (* 4
21324 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
21325 Do not rely on undefined behavior after integer overflow.
21326
21327 merge count_size_as_multibyte, parse_str_to_multibyte
21328 * character.c, character.h (count_size_as_multibyte):
21329 Rename from parse_str_to_multibyte; all uses changed.
21330 Check for integer overflow.
21331 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
21332 since it's now a duplicate of the other. This is more of
21333 a character than a buffer op, so better that it's in character.c.
21334 * fns.c, print.c: Adjust to above changes.
21335
213362011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>

21348 (crypto_hash_function): Now static.
21349 Fix pointer signedness problems. Avoid unnecessary initializations.
21350
213512011-05-27 Chong Yidong <cyd@stupidchicken.com>

21362 (x_handle_selection_request, lisp_data_to_selection_data)
21363 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
21364 (x_own_selection, x_get_local_selection, x_convert_selection):
21365 New arg, specifying work frame. Use terminal-local Vselection_alist.
21366 (some_frame_on_display): Delete unused function.
21367 (Fx_own_selection_internal, Fx_get_selection_internal)
21368 (Fx_disown_selection_internal, Fx_selection_owner_p)
21369 (Fx_selection_exists_p): New optional frame arg.
21370 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
21371 (x_handle_selection_clear): Don't treat other terminals with the
21372 same keyboard specially. Use the terminal-local Vselection_alist.
21373 (x_clear_frame_selections): Use Frun_hook_with_args.
21374
21375 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
21376
21377 * xterm.h: Add support for those atoms.
21378
213792011-05-26 Chong Yidong <cyd@stupidchicken.com>
21380
21381 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
21382 (converted_selections, conversion_fail_tag): New global variables.
21383 (x_selection_request_lisp_error): Free the above.
21384 (x_get_local_selection): Remove unnecessary code.
21385 (x_reply_selection_request): Args changed; handle arbitrary array
21386 of converted selections stored in converted_selections.
21387 Separate the XChangeProperty and SelectionNotify steps.
21388 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
21389 (x_convert_selection): New function.
21390 (x_handle_selection_event): Simplify.
21391 (x_get_foreign_selection): Don't ignore incoming requests while
21392 waiting for an answer; this will fail when we implement
21393 SAVE_TARGETS, and seems unnecessary anyway.
21394 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
21395 (Vx_sent_selection_functions): Doc fix.
21396
213972011-05-26 Leo Liu <sdl.web@gmail.com>
21398
21399 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
21400
214012011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21402
21403 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
21404
21405 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
21406 for fringe update if it has periodic bitmap.
21407 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
21408 and fringe_bitmap_periodic_p.
21409
21410 * fringe.c (get_fringe_bitmap_data): New function.
21411 (draw_fringe_bitmap_1, update_window_fringes): Use it.
21412 (update_window_fringes): Record periodicity of fringe bitmap in glyph
21413 row. Mark glyph row for fringe update if periodicity changed.
21414
21415 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
21416 for fringe update unless it has periodic bitmap.
21417
214182011-05-25 Kenichi Handa <handa@m17n.org>
21419
21420 * xdisp.c (get_next_display_element): Set correct it->face_id for
21421 a static composition.
21422
214232011-05-24 Leo Liu <sdl.web@gmail.com>
21424
21425 * deps.mk (fns.o):
21426 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
21427
21428 * fns.c (crypto_hash_function, Fsha1): New function.
21429 (Fmd5): Use crypto_hash_function.
21430 (syms_of_fns): Add Ssha1.
21431
214322011-05-22 Paul Eggert <eggert@cs.ucla.edu>
21433
21434 * gnutls.c: Remove unused macros.
21435 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
21436 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
21437 Remove macros that are defined and never used.
21438 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
21439
214402011-05-22 Chong Yidong <cyd@stupidchicken.com>
21441
21442 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
21443 (Fx_get_selection_internal): Minor cleanup.
21444 (Fx_own_selection_internal): Rename arguments for consistency with
21445 select.el.
21446
214472011-05-22 Paul Eggert <eggert@cs.ucla.edu>
21448
21449 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
21450
214512011-05-22 Chong Yidong <cyd@stupidchicken.com>
21452
21453 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
21454
214552011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21456
21457 * dispnew.c (scrolling_window): Don't exclude the case that the
21458 last enabled row in the desired matrix touches the bottom boundary.
21459
214602011-05-21 Glenn Morris <rgm@gnu.org>
21461
21462 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
21463 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
21464 and add some more files.
21465
214662011-05-20 Eli Zaretskii <eliz@gnu.org>
21467
21468 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
21469 report_file_error introduced by the change from 2011-05-07.
21470
214712011-05-20 Paul Eggert <eggert@cs.ucla.edu>
21472
21473 * systime.h (Time): Define only if emacs is defined.
21474 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
21475 where the include path doesn't have X11/X.h by default. See
21476 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
21477
214782011-05-20 Kenichi Handa <handa@m17n.org>
21479
21480 * composite.c (find_automatic_composition): Fix previous change.
21481
214822011-05-20 Glenn Morris <rgm@gnu.org>
21483
21484 * lisp.mk: New file, split from Makefile.in.
21485 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
21486 (shortlisp): Remove.
21487 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
21488
214892011-05-19 Glenn Morris <rgm@gnu.org>
21490
21491 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
21492 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
21493 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
21494 (lisp): Set the order to that of loadup.el.
21495 (shortlisp): Make it a copy of $lisp.
21496 (SOME_MACHINE_LISP): Remove.
21497 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
21498 Use just $shortlisp, not $SOME_MACHINE_LISP too.
21499
215002011-05-18 Kenichi Handa <handa@m17n.org>
21501
21502 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
21503 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
21504 (find_automatic_composition): Mostly rewrite for efficiency.
21505
215062011-05-18 Juanma Barranquero <lekktu@gmail.com>
21507
21508 * makefile.w32-in: Update dependencies.
21509
215102011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
21511
21512 * menu.c: Include limits.h (fixes the MS-Windows build broken by
21513 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
21514
215152011-05-18 Paul Eggert <eggert@cs.ucla.edu>
21516
21517 Fix some integer overflow issues, such as string length overflow.
21518
21519 * insdel.c (count_size_as_multibyte): Check for string overflow.
21520
21521 * character.c (lisp_string_width): Check for string overflow.
21522 Use EMACS_INT, not int, for string indexes and lengths; in
21523 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
21524 the resulting string length overflows an EMACS_INT; instead,
21525 report a string overflow if no precision given. When checking for
21526 precision exhaustion, use a check that cannot possibly have
21527 integer overflow. (Bug#8675)
21528 * character.h (lisp_string_width): Adjust to new signature.
21529
21530 * alloc.c (string_overflow): New function.
21531 (Fmake_string): Use it. This doesn't change behavior, but saves
21532 a few bytes and will simplify future changes.
21533 * character.c (string_escape_byte8): Likewise.
21534 * lisp.h (string_overflow): New decl.
21535
21536 Fixups, following up to the user-interface timestamp change.
21537 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
21538 for UI timestamps, instead of unsigned long.
21539 * msdos.c (mouse_get_pos): Likewise.
21540 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
21541 * w32gui.h (Time): Define by including "systime.h" rather than by
21542 declaring it ourselves. (Bug#8664)
21543
21544 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
21545 * image.c (clear_image_cache): Likewise.
21546
21547 * term.c (term_mouse_position): Don't assume time_t wraparound.
21548
21549 Be more systematic about user-interface timestamps.
21550 Before, the code sometimes used 'Time', sometimes 'unsigned long',
21551 and sometimes 'EMACS_UINT', to represent these timestamps.
21552 This change causes it to use 'Time' uniformly, as that's what X uses.
21553 This makes the code easier to follow, and makes it easier to catch
21554 integer overflow bugs such as Bug#8664.
21555 * frame.c (Fmouse_position, Fmouse_pixel_position):
21556 Use Time, not unsigned long, for user-interface timestamps.
21557 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
21558 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
21559 * keyboard.h (last_event_timestamp): Likewise.
21560 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
21561 * menu.h (xmenu_show): Likewise.
21562 * term.c (term_mouse_position): Likewise.
21563 * termhooks.h (struct input_event.timestamp): Likewise.
21564 (struct terminal.mouse_position_hook): Likewise.
21565 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
21566 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
21567 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
21568 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
21569 what it was before.
21570 * menu.h, termhooks.h: Include "systime.h", for Time.
21571
21572 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
21573 Don't assume that the difference between two unsigned long values
21574 can fit into an integer. At this point, we know button_down_time
21575 <= event->timestamp, so the difference must be nonnegative, so
21576 there's no need to cast the result if double-click-time is
21577 nonnegative, as it should be; check that it's nonnegative, just in
21578 case. This bug is triggered when events are more than 2**31 ms
21579 apart (about 25 days). (Bug#8664)
21580
21581 * xselect.c (last_event_timestamp): Remove duplicate decl.
21582 (x_own_selection): Remove needless cast to unsigned long.
21583
21584 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
21585 that always fit in int. Use a sentinel instead of a counter, to
21586 avoid a temp and to allay GCC's concerns about possible int overflow.
21587 * frame.h (struct frame): Use int for menu_bar_items_used
21588 instead of EMACS_INT, since it always fits in int.
21589
21590 * menu.c (grow_menu_items): Check for int overflow.
21591
21592 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
21593
21594 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
21595 Before, the code was not consistent. These values cannot exceed
21596 2**31 - 1 so there's no need to make them unsigned.
21597 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
21598 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
21599 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
21600 as modifiers.
21601 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
21602
21603 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
21604 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
21605 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
21606 presumably because the widths might not match.
21607
21608 * window.c (size_window): Avoid needless test at loop start.
21609
216102011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
21611
21612 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
21613
216142011-05-12 Drew Adams <drew.adams@oracle.com>
21615
21616 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
21617
216182011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21619
21620 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
21621 `width' to `bar_area_x' and `bar_area_width', respectively.
21622 (x_scroll_run): Take account of fringe background extension.
21623
21624 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
21625 Rename local vars `left' and `width' to `bar_area_x' and
21626 `bar_area_width', respectively.
21627 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
21628 background extension.
21629
216302011-05-10 Jim Meyering <meyering@redhat.com>
21631
21632 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
21633
216342011-05-10 Juanma Barranquero <lekktu@gmail.com>
21635
21636 * image.c (Finit_image_library): Return t for built-in image types,
21637 like pbm and xbm. (Bug#8640)
21638
216392011-05-09 Andreas Schwab <schwab@linux-m68k.org>
21640
21641 * w32menu.c (set_frame_menubar): Fix submenu allocation.
21642
216432011-05-07 Eli Zaretskii <eliz@gnu.org>
21644
21645 * w32console.c (Fset_screen_color): Doc fix.
21646 (Fget_screen_color): New function.
21647 (syms_of_ntterm): Defsubr it.
21648
21649 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
21650 unlink the temporary file if Fcall_process didn't create it in the
21651 first place.
21652 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
21653 child process will be redirected to a file specified with `:file'.
21654 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
21655 cue to call_process_cleanup not to close that handle.
21656
216572011-05-07 Ben Key <bkey76@gmail.com>
21658
21659 * makefile.w32-in: The bootstrap-temacs rule now makes use of
21660 one of two shell specific rules, either bootstrap-temacs-CMD or
21661 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
21662 to the previous implementation of the bootstrap-temacs rule.
21663 The bootstrap-temacs-CMD rule is similar to the previous
21664 implementation of the bootstrap-temacs rule except that it
21665 makes use of the ESC_CFLAGS variable instead of the CFLAGS
21666 variable.
21667
21668 These changes, along with some changes to nt/configure.bat,
21669 nt/gmake.defs, and nt/nmake.defs, are required to extend my
21670 earlier fix to add support for --cflags and --ldflags options
21671 that include quotes so that it works whether make uses cmd or
21672 sh as the shell.
21673
216742011-05-06 Michael Albinus <michael.albinus@gmx.de>
21675
21676 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
21677 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
21678 is a constant.
21679 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
21680 a string. Handle both cases.
21681 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
21682 (Fdbus_register_method): Use Qinvalid_function.
21683
216842011-05-06 Juanma Barranquero <lekktu@gmail.com>
21685
21686 * makefile.w32-in: Update dependencies.
21687 (LISP_H): Add inttypes.h and stdin.h.
21688 (PROCESS_H): Add unistd.h.
21689
216902011-05-06 Eli Zaretskii <eliz@gnu.org>
21691
21692 * lread.c: Include limits.h (fixes the MS-Windows build broken by
21693 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
21694
216952011-05-06 Paul Eggert <eggert@cs.ucla.edu>
21696
21697 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
21698
21699 * term.c (vfatal): Remove stray call to va_end.
21700 It's not needed and the C Standard doesn't allow it here anyway.
21701
21702 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
21703 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
21704
21705 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
21706 bytes.
21707
21708 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
21709
21710 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
21711
21712 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
21713
21714 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
21715
21716 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
21717
21718 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
21719 * charset.c (Fdefine_charset_internal): Don't initialize
21720 charset.code_space[15]. The value was garbage, on hosts with
21721 32-bit int (Bug#8600).
21722
21723 * lread.c (read_integer): Be more consistent with string-to-number.
21724 Use string_to_number to do the actual conversion; this avoids
21725 rounding errors and fixes some other screwups. Without this fix,
21726 for example, #x1fffffffffffffff was misread as -2305843009213693952.
21727 (digit_to_number): Move earlier, for benefit of read_integer.
21728 Return -1 if the digit is out of range for the base, -2 if it is
21729 not a digit in any supported base. (Bug#8602)
21730
21731 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
21732
21733 * dispnew.c (scrolling_window): Return 1 if we scrolled,
21734 to match comment at start of function. This also removes a
21735 GCC warning about overflow in a 32+64-bit port.
21736
21737 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
21738
21739 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
21740 Reported by Stefan Monnier in
21741 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
21742 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
21743 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
21744
21745 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
21746 (EMACS_UINTPTR): Likewise, with uintptr_t.
21747
21748 * lisp.h: Prefer 64-bit EMACS_INT if available.
21749 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
21750 on 32-bit hosts that have 64-bit int, so that they can access
21751 large files.
21752 However, temporarily disable this change unless the temporary
21753 symbol WIDE_EMACS_INT is defined.
21754
21755 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
21756
21757 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
21758 This removes an assumption that EMACS_INT and long are the same
21759 width as pointers. The assumption is true for Emacs porting targets
21760 now, but we want to make other targets possible.
21761 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
21762 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
21763 In the rest of the code, change types of integers that hold casted
21764 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
21765 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
21766 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
21767 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
21768 No need to cast type when ORing.
21769 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
21770 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
21771 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
21772 assume EMACS_INT is the same width as char *.
21773 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
21774 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
21775 Remove no-longer-needed casts.
21776 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
21777 (xg_tool_bar_help_callback, xg_make_tool_item):
21778 Use EMACS_INTPTR to hold an integer
21779 that will be cast to void *; this can avoid a GCC warning
21780 if EMACS_INT is not the same width as void *.
21781 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
21782 * xdisp.c (display_echo_area_1, resize_mini_window_1):
21783 (current_message_1, set_message_1):
21784 Use a local to convert to proper width without a cast.
21785 * xmenu.c (dialog_selection_callback): Likewise.
21786
21787 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
21788 Also, don't assume VALBITS / RAND_BITS is less than 5,
21789 and don't rely on undefined behavior when shifting a 1 left into
21790 the sign bit.
21791 * lisp.h (get_random): Change signature to match.
21792
21793 * lread.c (hash_string): Use size_t, not int, for hash computation.
21794 Normally we prefer signed values; but hashing is special, because
21795 it's better to use unsigned division on hash table sizes so that
21796 the remainder is nonnegative. Also, size_t is the natural width
21797 for hashing into memory. The previous code used 'int', which doesn't
21798 retain enough info to hash well into very large tables.
21799 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
21800
21801 * dbusbind.c: Don't possibly lose pointer info when converting.
21802 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
21803 Use XPNTR rather than XHASH, so that the high-order bits of
21804 the pointer aren't lost when converting through void *.
21805
21806 * eval.c (Fautoload): Don't double-shift a pointer.
21807
21808 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
21809
218102011-05-06 Juanma Barranquero <lekktu@gmail.com>
21811
21812 * gnutls.c (DEF_GNUTLS_FN):

21814
218152011-05-05 Andreas Schwab <schwab@linux-m68k.org>
21816
21817 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
21818 marker. (Bug#8610)
21819
218202011-05-05 Eli Zaretskii <eliz@gnu.org>

21842 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
21843 Remove unused parameter `fildes'.
21844 * process.c (read_process_output, send_process): Don't pass it.
21845
218462011-05-04 Juanma Barranquero <lekktu@gmail.com>
21847
21848 Fix previous change: the library cache is defined in w32.c.
21849 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
21850 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
21851

21888 Initialize and staticpro them.

21923
219242011-05-01 Andreas Schwab <schwab@linux-m68k.org>
21925

21927
21928 * sysdep.c (wait_for_termination_1): Make static.
21929 (wait_for_termination, interruptible_wait_for_termination):
21930 Move after wait_for_termination_1.
21931
219322011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
21933
21934 * sysdep.c (interruptible_wait_for_termination): New function

22001
22002 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

22014
22015 Improve `doprnt' and its usage. (Bug#8545)
22016 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
22017 `format_end'. Remove support for %l as a conversion specifier.
22018 Don't use xrealloc. Improve diagnostics when the %l size modifier
22019 is used. Update the commentary.
22020
22021 * eval.c (verror): Simplify calculation of size_t.
22022
22023 * coding.c (Ffind_operation_coding_system): Fix diagnostic error

22029 change.
22030
220312011-04-27 Paul Eggert <eggert@cs.ucla.edu>
22032
22033 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
22034 This makes this file independent of the recent pseudovector change.
22035
220362011-04-26 Paul Eggert <eggert@cs.ucla.edu>
22037
22038 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
22039
22040 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
22041 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
22042 Remove unused local.
22043 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
22044
22045 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
22046 GCC 4.6.0 optimizes based on type-based alias analysis.
22047 For example, if b is of type struct buffer * and v of type struct
22048 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
22049 != &v->size, and therefore "v->size = 1; b->size = 2; return
22050 v->size;" must therefore return 1. This assumption is incorrect
22051 for Emacs, since it type-puns struct Lisp_Vector * with many other
22052 types. To fix this problem, this patch adds a new type struct
22053 vectorlike_header that documents the constraints on layout of vectors
22054 and pseudovectors, and helps optimizing compilers not get fooled
22055 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
22056 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
22057 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
22058 the size member.
22059 (XSETPVECTYPE): Rewrite in terms of new macro.
22060 (XSETPVECTYPESIZE): New macro, specifying both type and size.
22061 This is a bit clearer, and further avoids the possibility of
22062 undesirable aliasing.
22063 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
22064 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
22065 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
22066 since Lisp_Subr is a special case (no "next" field).
22067 (ASIZE): Now uses header.size rather than size.
22068 All previous uses of XVECTOR (foo)->size replaced to use this macro,
22069 to avoid the hassle of writing XVECTOR (foo)->header.size.
22070 (struct vectorlike_header): New type.
22071 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
22072 object, to help avoid aliasing.
22073 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
22074 (SUBRP): Likewise, since Lisp_Subr is a special case.
22075 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
22076 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
22077 (struct Lisp_Hash_Table): Combine first two members into a single
22078 struct vectorlike_header member. All uses of "size" and "next" members
22079 changed to be "header.size" and "header.next".
22080 * buffer.h (struct buffer): Likewise.
22081 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
22082 * frame.h (struct frame): Likewise.
22083 * process.h (struct Lisp_Process): Likewise.
22084 * termhooks.h (struct terminal): Likewise.
22085 * window.c (struct save_window_data, struct saved_window): Likewise.
22086 * window.h (struct window): Likewise.
22087 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
22088 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
22089 * buffer.c (init_buffer_once): Likewise.
22090 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
22091 special case.
22092 * process.c (Fformat_network_address): Use local var for size,
22093 for brevity.
22094
22095 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
22096
22097 Make the Lisp reader and string-to-float more consistent (Bug#8525)
22098 * data.c (atof): Remove decl; no longer used or needed.
22099 (digit_to_number): Move to lread.c.
22100 (Fstring_to_number): Use new string_to_number function, to be
22101 consistent with how the Lisp reader treats infinities and NaNs.
22102 Do not assume that floating-point numbers represent EMACS_INT
22103 without losing information; this is not true on most 64-bit hosts.
22104 Avoid double-rounding errors, by insisting on integers when
22105 parsing non-base-10 numbers, as the documentation specifies.
22106 * lisp.h (string_to_number): New decl, replacing ...
22107 (isfloat_string): Remove.
22108 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
22109 (read1): Do not accept +. and -. as integers; this
22110 appears to have been a coding error. Similarly, do not accept
22111 strings like +-1e0 as floating point numbers. Do not report
22112 overflow for integer overflows unless the base is not 10 which
22113 means we have no simple and reliable way to continue.
22114 Break out the floating-point parsing into a new
22115 function string_to_number, so that Fstring_to_number parses
22116 floating point numbers consistently with the Lisp reader.
22117 (digit_to_number): Move here from data.c. Make it static inline.
22118 (E_CHAR, EXP_INT): Remove, replacing with ...
22119 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
22120 (string_to_number): New function, replacing isfloat_string.
22121 This function checks for valid syntax and produces the resulting
22122 Lisp float number too. Rework it so that string-to-number
22123 no longer mishandles examples like "1.0e+". Use strtoumax,
22124 so that overflow for non-base-10 numbers is reported only when
22125 there's no portable and simple way to convert to floating point.
22126
22127 * textprop.c (set_text_properties_1): Rewrite for clarity,
22128 and to avoid GCC warning about integer overflow.
22129
22130 * intervals.h (struct interval): Use EMACS_INT for members
22131 where EMACS_UINT might cause problems. See
22132 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
22133 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
22134 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
22135 All uses changed.
22136 (offset_intervals): Tell GCC not to worry about length overflow
22137 when negating a negative length.
22138
22139 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
22140 (overrun_check_free): Likewise.
22141
22142 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
22143 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
22144 word size.
22145
22146 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
22147 (gnutls_make_error): Rename local to avoid shadowing.
22148 (gnutls_emacs_global_deinit): ifdef out; not used.
22149 (Fgnutls_boot): Use const for pointer to readonly storage.
22150 Comment out unused local. Fix pointer signedness problems.
22151
22152 * lread.c (openp): Don't stuff size_t into an 'int'.
22153 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
22154 about possible signed overflow.
22155
22156 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
22157 (GDK_KEY_g): Don't define if already defined.
22158 (xg_prepare_tooltip): Avoid pointer signedness problem.
22159 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
22160
22161 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
22162 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
22163
22164 * xfns.c (Fx_window_property): Simplify a bit,
22165 to make a bit faster and to avoid GCC 4.6.0 warning.
22166 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
22167
22168 * fns.c (internal_equal): Don't assume size_t fits in int.
22169
22170 * alloc.c (compact_small_strings): Tighten assertion a little.
22171
22172 Replace pEd with more-general pI, and fix some printf arg casts.
22173 * lisp.h (pI): New macro, generalizing old pEd macro to other
22174 conversion specifiers. For example, use "...%"pI"d..." rather
22175 than "...%"pEd"...".
22176 (pEd): Remove. All uses replaced with similar uses of pI.
22177 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
22178 * alloc.c (check_pure_size): Don't overflow by converting size to int.
22179 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
22180 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
22181 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
22182 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
22183 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
22184 64-bit hosts.
22185 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
22186 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
22187 * print.c (safe_debug_print, print_object): Likewise.
22188 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
22189 to int.
22190 Use pI instead of if-then-else-abort. Use %p to avoid casts,
22191 avoiding the 0 flag, which is not portable.
22192 * process.c (Fmake_network_process): Use pI to avoid cast.
22193 * region-cache.c (pp_cache): Likewise.
22194 * xdisp.c (decode_mode_spec): Likewise.
22195 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
22196 behavior on 64-bit hosts with printf arg.
22197 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
22198 (x_stop_queuing_selection_requests): Likewise.
22199 (x_get_window_property): Don't truncate byte count to an 'int'
22200 when tracing.
22201
22202 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
22203 here, since it parses constructs like leading '-' and spaces,
22204 which are not wanted; and it overflows with large numbers.
22205 Instead, simply match F[0-9]+, which is what is wanted anyway.
22206
22207 * alloc.c: Remove unportable assumptions about struct layout.
22208 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
22209 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
22210 (allocate_vectorlike, make_pure_vector): Use the new macros,
22211 plus offsetof, to remove unportable assumptions about struct layout.
22212 These assumptions hold on all porting targets that I know of, but
22213 they are not guaranteed, they're easy to remove, and removing them
22214 makes further changes easier.
22215
22216 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
22217 This doesn't fix a bug but makes the code clearer.
22218 (string_overrun_cookie): Now const. Use initializers that
22219 don't formally overflow signed char, to avoid warnings.
22220 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
22221 can cause Emacs to crash when string overrun checking is enabled.
22222 (allocate_buffer): Don't assume sizeof (struct buffer) is a
22223 multiple of sizeof (EMACS_INT); it need not be, if
22224 alignof(EMACS_INT) < sizeof (EMACS_INT).
22225 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
22226
222272011-04-26 Juanma Barranquero <lekktu@gmail.com>
22228
22229 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
22230

22232
22233 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
22234 supposed to be handshaking. (Bug#8556)
22235 Reported by Paul Eggert <eggert@cs.ucla.edu>.
22236
222372011-04-26 Daniel Colascione <dan.colascione@gmail.com>
22238
22239 * lisp.h (Qdebug): List symbol.
22240 * eval.c (Qdebug): Restore global linkage.
22241 * keyboard.c (debug-on-event): New variable.
22242 (handle_user_signal): Break into debugger when debug-on-event
22243 matches the current signal symbol.
22244
222452011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
22246
22247 * alloc.c (check_sblock, check_string_bytes)
22248 (check_string_free_list): Convert to standard C.
22249
222502011-04-25 Teodor Zlatanov <tzz@lifelogs.com>

22253
222542011-04-25 Eli Zaretskii <eliz@gnu.org>
22255
22256 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
22257 "cast to pointer from integer of different size".
22258
22259 Improve doprnt and its use in verror. (Bug#8545)
22260 * doprnt.c (doprnt): Document the set of format control sequences
22261 supported by the function. Use SAFE_ALLOCA instead of always
22262 using `alloca'.
22263
22264 * eval.c (verror): Don't limit the buffer size at size_max-1, that
22265 is one byte too soon. Don't use xrealloc; instead xfree and
22266 xmalloc anew.
22267
222682011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
22269
22270 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
22271 callbacks stage.
22272
22273 * gnutls.c: Renamed global_initialized to
22274 gnutls_global_initialized. Added internals for the
22275 :verify-hostname-error, :verify-error, and :verify-flags
22276 parameters of `gnutls-boot' and documented those parameters in the
22277 docstring. Start callback support.
22278 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
22279 unless a fatal error occurred. Call gnutls_alert_send_appropriate
22280 on error. Return error code.
22281 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
22282 (emacs_gnutls_read): Likewise.
22283 (Fgnutls_boot): Return handshake error code.

22306 display_replaced_before_p argument into display_replaced_p, to
22307 make it consistent with the commentary. Fix typos in the
22308 commentary.
22309
22310 * textprop.c (syms_of_textprop): Remove dead code.
22311 (copy_text_properties): Delete obsolete commentary about an
22312 interface that was deleted long ago. Fix typos in the description
22313 of arguments.
22314
22315 * msdos.c (XMenuActivate, XMenuAddSelection): Adjust argument list
22316 to changes in oldXMenu/XMenu.h from 2011-04-16.
22317 <menu_help_message, prev_menu_help_message>: Constify.

22321 * msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
22322 to changes in oldXMenu/XMenu.h from 2011-04-16.

22325 * xfaces.c <Qunspecified>: Make extern again.
22326
22327 * syntax.c: Include sys/types.h before including regex.h, as
22328 required by POSIX.
22329
22330 * doc.c (get_doc_string): Improve the format passed to `error'.
22331
22332 * doprnt.c (doprnt): Improve commentary.
22333
22334 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
22335
22336 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
22337 them with etags.
22338
22339 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
22340 changes in globals.h immediately force recompilation.
22341 (TAGS): Depend on $(CURDIR)/m/intel386.h and
22342 $(CURDIR)/s/ms-w32.h.
22343 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

22348
223492011-04-23 Eli Zaretskii <eliz@gnu.org>
22350
22351 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
22352 * doprnt.c: Include limits.h.
22353 (SIZE_MAX): New macro.
22354 (doprnt): Return a size_t value. 2nd arg is now size_t.
22355 Many local variables are now size_t instead of int or unsigned.
22356 Improve overflow protection. Support `l' modifier for integer
22357 conversions. Support %l conversion. Don't assume an EMACS_INT
22358 argument for integer conversions and for %c.
22359
22360 * lisp.h (doprnt): Restore prototype.
22361
22362 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on

22375 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
22376
22377 * callint.c (Fcall_interactively): When displaying error message
22378 about invalid control letter, pass the character's codepoint, not
22379 a pointer to its multibyte form. Improve display of the character
22380 in octal and display also its hex code.
22381
22382 * character.c (char_string): Use %x to display the (unsigned)
22383 codepoint of an invalid character, to avoid displaying a bogus
22384 negative value.
22385
22386 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
22387 `error', not SYMBOL_NAME itself.

22389 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
22390 character arguments to `error'.
22391
22392 * charset.c (check_iso_charset_parameter): Fix incorrect argument
22393 to `error' in error message about FINAL_CHAR argument. Make sure
22394 FINAL_CHAR is a character, and use %c when it is passed as
22395 argument to `error'.
22396
223972011-04-23 Eli Zaretskii <eliz@gnu.org>

22440 definition for no-X builds.
22441
224422011-04-16 Paul Eggert <eggert@cs.ucla.edu>
22443
22444 Static checks with GCC 4.6.0 and non-default toolkits.

22474 it.
22475
22476 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
22477 so that we aren't warned about unused symbols.

22583
22584 * nsfont.m: Fixed bugs in ns_get_family and
22585 ns_descriptor_to_entity that were caused by using free to
22586 deallocate memory blocks that were allocated by xmalloc (via
22587 xstrdup). This caused Emacs to crash when compiled with
22588 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
22589 --enable-checking=xmallocoverrun). xfree is now used to
22590 deallocate these memory blocks.

22935 * category.h: ... from here.
22936 * category.c (check_category_table, set_category_set): Now static.
22937
22938 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.

22940
22941 * buffer.c (buffer_count): Remove unused var.
22942
22943 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
22944 so that it's not optimized away.
22945 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
22946 * dispextern.h (bidi_dump_cached_states): Remove, since it's
22947 exported only to the debugger.
22948
22949 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
22950 * atimer.h (run_all_atimers): Remove; not exported.
22951
22952 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
22953 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
22954 was inaccessible from Lisp.
22955 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
22956 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
22957
22958 alloc.c: Import and export fewer symbols, and remove unused items.
22959 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
22960 is defined.
22961 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
22962 it's not optimized away by whole-program optimization.
22963 (message_enable_multibyte, free_misc): Remove.
22964 (catchlist, handlerlist, mark_backtrace):
22965 Declare only if BYTE_MARK_STACK.

22976 * xdisp.c (message_enable_multibyte): Now static.
22977
22978 Declare Lisp_Object Q* variables to be 'static' if not exported.
22979 This makes it easier for human readers (and static analyzers)
22980 to see whether these variables are used from other modules.
22981 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
22982 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

22992 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
22993
22994 * lisp.h (DEFINE_FUNC): Make sname 'static'.
22995
22996 Make Emacs functions such as Fatom 'static' by default.
22997 This makes it easier for human readers (and static analyzers)
22998 to see whether these functions can be called from other modules.
22999 DEFUN now defines a static function. To make the function external
23000 so that it can be used in other C modules, use the new macro DEFUE.
23001 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
23002 (Finit_image_library):
23003 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
23004 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
23005 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
23006 Remove decls, since these functions are now static.
23007 (Funintern, Fget_internal_run_time): New decls, since these functions
23008 were already external.
23009
23010 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
23011 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

23017 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
23018 Mark functions with DEFUE instead of DEFUN,
23019 if they are used in other modules.
23020 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
23021 decls for now-static functions.
23022 * buffer.h (Fdelete_overlay): Remove decl.
23023 * callproc.c (Fgetenv_internal): Mark as internal.

23052
230532011-04-14 Andreas Schwab <schwab@linux-m68k.org>
23054
23055 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
23056 change. (Bug#8496)
23057
230582011-04-13 Eli Zaretskii <eliz@gnu.org>
23059
23060 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
23061 when at ZV. (Bug#8487)
23062
230632011-04-12 Andreas Schwab <schwab@linux-m68k.org>
23064
23065 * charset.c (Fclear_charset_maps): Use xfree instead of free.
23066 (Bug#8437)
23067 * keyboard.c (parse_tool_bar_item): Likewise.
23068 * sound.c (sound_cleanup, alsa_close): Likewise.

23072
23073 * alloc.c (overrun_check_malloc, overrun_check_realloc)
23074 (overrun_check_free): Protoize.
23075
230762011-04-12 Paul Eggert <eggert@cs.ucla.edu>
23077
23078 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
23079 since callers should never pass a negative size.
23080 Change the signature to match that of plain 'read' and 'write'; see
23081 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
23082 * lisp.h: Update prototypes of emacs_write and emacs_read.
23083
230842011-04-11 Eli Zaretskii <eliz@gnu.org>
23085
23086 * xdisp.c (redisplay_window): Don't try to determine the character
23087 position of the scroll margin if the window start point w->startp
23088 is outside the buffer's accessible region. (Bug#8468)
23089
230902011-04-10 Eli Zaretskii <eliz@gnu.org>
23091
23092 Fix write-region and its subroutines for buffers > 2GB.
23093 * fileio.c (a_write, e_write): Modify declaration of arguments and
23094 local variables to support buffers larger than 2GB.
23095 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
23096
23097 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
23098 argument, local variables, and return value.
23099
23100 * lisp.h: Update prototypes of emacs_write and emacs_read.
23101
23102 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
23103
231042011-04-10 Paul Eggert <eggert@cs.ucla.edu>
23105
23106 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
23107
23108 Fix more problems found by GCC 4.6.0's static checks.
23109
23110 * xdisp.c (vmessage): Use a better test for character truncation.
23111
23112 * charset.c (load_charset_map): <, not <=, for optimization,
23113 and to avoid potential problems with integer overflow.
23114 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
23115 * casetab.c (set_identity, shuffle): Likewise.
23116 * editfns.c (Fformat): Likewise.
23117 * syntax.c (skip_chars): Likewise.
23118
23119 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
23120 This also lets GCC 4.6.0 generate slightly better loop code.
23121
23122 * callint.c (Fcall_interactively): <, not <=, for optimization.
23123 (Fcall_interactively): Count the number of arguments produced,
23124 not the number of arguments given. This is simpler and lets GCC
23125 4.6.0 generate slightly better code.
23126
23127 * ftfont.c: Distingish more carefully between FcChar8 and char.
23128 The previous code passed unsigned char * to a functions like
23129 strlen and xstrcasecmp that expect char *, which does not
23130 conform to the C standard.
23131 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
23132 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
23133 char * when the C standard requires it.
23134
23135 * keyboard.c (read_char): Remove unused var.
23136
23137 * eval.c: Port to Windows vsnprintf (Bug#8435).
23138 Include <limits.h>.
23139 (SIZE_MAX): Define if the headers do not.
23140 (verror): Do not give up if vsnprintf returns a negative count.
23141 Instead, grow the buffer. This ports to Windows vsnprintf, which
23142 does not conform to C99. Problem reported by Eli Zaretskii.
23143 Also, simplify the allocation scheme, by avoiding the need for
23144 calling realloc, and removing the ALLOCATED variable.
23145
23146 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
23147
23148 Remove invocations of doprnt, as Emacs now uses vsnprintf.
23149 But keep the doprint source code for now, as we might revamp it
23150 and use it again (Bug#8435).
23151 * lisp.h (doprnt): Remove.
23152 * Makefile.in (base_obj): Remove doprnt.o.
23153 * deps.mk (doprnt.o): Remove.
23154
23155 error: Print 32- and 64-bit integers portably (Bug#8435).
23156 Without this change, on typical 64-bit hosts error ("...%d...", N)
23157 was used to print both 32- and 64-bit integers N, which relied on
23158 undefined behavior.
23159 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
23160 * lisp.h (error, verror): Mark as printf-like functions.
23161 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
23162 Report overflow in size calculations when allocating printf buffer.
23163 Do not truncate output string at its first null byte.
23164 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
23165 Truncate the output at a character boundary, since vsnprintf does not
23166 do that.
23167 * charset.c (check_iso_charset_parameter): Convert internal
23168 character to string before calling 'error', since %c now has the
23169 printf meaning.
23170 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
23171 overflow when computing char to be passed to 'error'. Do not
23172 pass Lisp_Object to 'error'; pass the integer instead.
23173 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
23174 formatted with plain %d.
23175
23176 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
23177
23178 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
23179
23180 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
23181
23182 * xterm.c (x_catch_errors): Remove duplicate declaration.
23183
23184 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
23185
23186 * xdisp.c, lisp.h (message_nolog): Remove; unused.
23187
231882011-04-10 Jim Meyering <meyering@redhat.com>
23189
23190 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
23191 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
23192 return ssize_t not "int", and use size_t as the buffer length.
23193 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
23194 * gnutls.h: Update declarations.
23195 * process.c (read_process_output): Use ssize_t, to match.
23196 (send_process): Likewise.
23197
231982011-04-09 Chong Yidong <cyd@stupidchicken.com>
23199
23200 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
23201
232022011-04-09 Chong Yidong <cyd@stupidchicken.com>
23203
23204 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
23205 Use unsigned char, to match FcChar8 type definition.
23206
23207 * xterm.c (handle_one_xevent):
23208 * xmenu.c (create_and_show_popup_menu):
23209 * xselect.c (x_decline_selection_request)
23210 (x_reply_selection_request): Avoid type-punned deref of X events.
23211
232122011-04-09 Eli Zaretskii <eliz@gnu.org>
23213
23214 Fix some uses of `int' instead of EMACS_INT.
23215 * search.c (string_match_1, fast_string_match)
23216 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
23217 (scan_buffer, find_next_newline_no_quit)
23218 (find_before_next_newline, search_command, Freplace_match)
23219 (Fmatch_data): Make some `int' variables be EMACS_INT.
23220
23221 * xdisp.c (display_count_lines): 3rd argument and return value now
23222 EMACS_INT. All callers changed.
23223 (pint2hrstr): Last argument is now EMACS_INT.
23224
23225 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
23226 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
23227 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
23228 (decode_coding_utf_16, decode_coding_emacs_mule)
23229 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
23230 (decode_coding_ccl, decode_coding_charset)
23231 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
23232 (decode_coding_iso_2022, decode_coding_emacs_mule)
23233 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
23234 <char_offset, last_offset>: Declare EMACS_INT.
23235 (encode_coding_utf_8, encode_coding_utf_16)
23236 (encode_coding_emacs_mule, encode_invocation_designation)
23237 (encode_designation_at_bol, encode_coding_iso_2022)
23238 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
23239 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
23240 Declare EMACS_INT.
23241 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
23242 (encode_invocation_designation): Last argument P_NCHARS is now
23243 EMACS_INT.
23244 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
23245 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
23246
23247 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
23248 All users changed.
23249
23250 * ccl.c (Fccl_execute_on_string): Declare some variables
23251 EMACS_INT.
23252

23254
23255 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
23256

23258
23259 * process.c (Fformat_network_address): Doc fix.
23260
232612011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
23262
23263 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
23264
232652011-04-08 Chong Yidong <cyd@stupidchicken.com>
23266
23267 * keyboard.c (read_char): Call Lisp function help-form-show,
23268 instead of using internal_with_output_to_temp_buffer.
23269 (Qhelp_form_show): New var.
23270 (syms_of_keyboard): Use DEFSYM macro.
23271
23272 * print.c (internal_with_output_to_temp_buffer): Function deleted.
23273
23274 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
23275
232762011-04-06 Chong Yidong <cyd@stupidchicken.com>
23277
23278 * process.c (Flist_processes): Remove to Lisp.
23279 (list_processes_1): Delete.
23280
232812011-04-06 Eli Zaretskii <eliz@gnu.org>
23282
23283 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
23284

23304 printf-like functions.
23305 (tiff_load): Add casts to remove these marks before passing them
23306 to system-supplied API.
23307
23308 * eval.c (Fsignal): Remove excess argument to 'fatal'.
23309
23310 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
23311 This avoids several warnings with gcc -Wstrict-overflow.
23312 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
23313 directly, rather than having caller test rule sign. This avoids
23314 some unnecessary tests.
23315 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
23316 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
23317 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
23318
23319 * xfont.c (xfont_text_extents): Remove var that was set but not used.
23320 (xfont_open): Avoid unnecessary tests.
23321
23322 * composite.c (composition_gstring_put_cache): Use unsigned integer.
23323
23324 * composite.h, composite.c (composition_gstring_put_cache):
23325 Use EMACS_INT, not int, for length.
23326
23327 * composite.h (COMPOSITION_DECODE_REFS): New macro,
23328 breaking out part of COMPOSITION_DECODE_RULE.
23329 (COMPOSITION_DECODE_RULE): Use it.
23330 * composite.c (get_composition_id): Remove unused local vars,
23331 by using the new macro.
23332
23333 * textprop.c (set_text_properties_1): Change while to do-while,
23334 since the condition is always true at first.
23335
23336 * intervals.c (graft_intervals_into_buffer): Mark var as used.
23337 (interval_deletion_adjustment): Return unsigned value.
23338 All uses changed.
23339
23340 * process.c (list_processes_1, create_pty, read_process_output):
23341 (exec_sentinel): Remove vars that were set but not used.
23342 (create_pty): Remove unnecessary "volatile"s.
23343 (Fnetwork_interface_info): Avoid possibility of int overflow.
23344 (read_process_output): Do adaptive read buffering even if carryover.
23345 (read_process_output): Simplify nbytes computation if buffered.
23346
23347 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
23348
23349 * syntax.c (scan_words): Remove var that was set but not used.
23350 (update_syntax_table): Use unsigned instead of int.
23351
23352 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
23353 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
23354 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
23355
23356 * print.c (print_error_message): Avoid int overflow.
23357
23358 * font.c (font_list_entities): Redo for clarity,
23359 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
23360
23361 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
23362 (font_score): Avoid potential overflow in diff calculation.
23363
23364 * fns.c (substring_both): Remove var that is set but not used.
23365 (sxhash): Redo loop for clarity and to avoid wraparound warning.
23366
23367 * eval.c (funcall_lambda): Rename local to avoid shadowing.
23368
23369 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
23370 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
23371 can always succeed if overflow has undefined behavior.
23372
23373 * search.c (boyer_moore, wordify): Remove vars set but not used.
23374 (wordify): Omit three unnecessary tests.
23375
23376 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
23377 All callers changed. This avoids the need for an unused var.
23378
23379 * casefiddle.c (casify_region): Remove var that is set but not used.
23380
23381 * dired.c (file_name_completion): Remove var that is set but not used.
23382
23383 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
23384
23385 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
23386 (Finsert_file_contents): Remove unnecessary code checking fd.
23387
23388 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
23389 Check for integer overflow on size calculations.
23390
23391 * buffer.c (Fprevious_overlay_change): Remove var that is set
23392 but not used.
23393
23394 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
23395 Remove vars that are set but not used.
23396 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
23397 (timer_check_2): Mark vars as initialized.
23398
23399 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
23400

23403
23404 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
23405 that are set but not used.
23406
23407 * xfns.c (make_invisible_cursor): Don't return garbage
23408 if XCreateBitmapFromData fails (Bug#8410).
23409
23410 * xselect.c (x_get_local_selection, x_handle_property_notify):
23411 Remove vars that are set but not used.
23412
23413 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
23414 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
23415
23416 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
23417 Remove var that is set but not used.
23418 (scroll_bar_windows_size): Now size_t, not int.
23419 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
23420 Check for overflow.
23421
23422 * xfaces.c (realize_named_face): Remove vars that are set but not used.
23423 (map_tty_color) [!defined MSDOS]: Likewise.
23424
23425 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
23426
23427 * coding.c: Remove vars that are set but not used.
23428 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
23429 All callers changed.
23430 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
23431 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
23432 (decode_coding_charset): Remove vars that are set but not used.
23433
23434 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
23435 that is set but not used.
23436
23437 * print.c (print_object): Remove var that is set but not used.
23438
23439 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
23440 The gnulib version avoids calling malloc in the usual case,
23441 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
23442 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
23443 * filelock.c (current_lock_owner): Likewise.
23444 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
23445 * sysdep.c: Include allocator.h, careadlinkat.h.
23446 (emacs_no_realloc_allocator): New static constant.
23447 (emacs_readlink): New function.
23448 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
23449 ../lib/careadlinkat.h.
23450
234512011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
23452
23453 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
23454 first non-nil return value).
23455
234562011-04-03 Jan Djärv <jan.h.d@swipnet.se>
23457
23458 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
23459 if not defined (Bug#8403).
23460
234612011-04-02 Juanma Barranquero <lekktu@gmail.com>
23462
23463 * xdisp.c (display_count_lines): Remove parameter `start',
23464 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
23465 (get_char_face_and_encoding): Remove parameter `multibyte_p',
23466 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
23467 (fill_stretch_glyph_string): Remove parameters `row' and `area',
23468 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
23469 and thereabouts. All callers changed.
23470 (get_per_char_metric): Remove parameter `f', unused since
23471 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
23472
234732011-04-02 Jim Meyering <meyering@redhat.com>
23474
23475 do not dereference NULL upon failed strdup
23476 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
23477 (ns_get_family): Likewise.
23478
234792011-04-02 Juanma Barranquero <lekktu@gmail.com>
23480
23481 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
23482
234832011-04-02 Jan Djärv <jan.h.d@swipnet.se>
23484
23485 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
23486 later (Bug#8403).
23487
234882011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
23489
23490 Add lexical binding.
23491
23492 * window.c (Ftemp_output_buffer_show): New fun.
23493 (Fsave_window_excursion):
23494 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
23495
23496 * lread.c (lisp_file_lexically_bound_p): New function.
23497 (Fload): Bind Qlexical_binding.
23498 (readevalloop): Remove `evalfun' arg.
23499 Bind Qinternal_interpreter_environment.
23500 (Feval_buffer): Bind Qlexical_binding.
23501 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
23502 Mark as dynamic.
23503 (syms_of_lread): Declare `lexical-binding'.
23504
23505 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
23506
23507 * keyboard.c (eval_dyn): New fun.
23508 (menu_item_eval_property): Use it.
23509
23510 * image.c (parse_image_spec): Use Ffunctionp.
23511
23512 * fns.c (concat, mapcar1): Accept byte-code-functions.
23513
23514 * eval.c (Fsetq): Handle lexical vars.
23515 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
23516 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
23517 (FletX, Flet): Obey lexical binding.
23518 (Fcommandp): Handle closures.
23519 (Feval): New `lexical' arg.
23520 (eval_sub): New function extracted from Feval. Use it almost
23521 everywhere where Feval was used. Look up vars in lexical env.
23522 Handle closures.
23523 (Ffunctionp): Move from subr.el.
23524 (Ffuncall): Handle closures.
23525 (apply_lambda): Remove `eval_flags'.
23526 (funcall_lambda): Handle closures and new byte-code-functions.
23527 (Fspecial_variable_p): New function.
23528 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
23529 but without exporting it to Lisp.
23530
23531 * doc.c (Fdocumentation, store_function_docstring):
23532 * data.c (Finteractive_form): Handle closures.
23533
23534 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
23535 interactive spec.
23536
23537 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
23538 New byte-codes.
23539 (exec_byte_code): New function extracted from Fbyte_code to handle new
23540 calling convention for byte-code-functions. Add new byte-codes.
23541
23542 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
23543
23544 * alloc.c (Fmake_symbol): Init new `declared_special' field.
23545
235462011-03-31 Juanma Barranquero <lekktu@gmail.com>
23547
23548 * xdisp.c (redisplay_internal): Fix prototype.
23549
235502011-03-31 Eli Zaretskii <eliz@gnu.org>
23551
23552 * xdisp.c (SCROLL_LIMIT): New macro.
23553 (try_scrolling): Use it when setting scroll_limit.
23554 Limit scrolling to 100 screen lines.
23555 (redisplay_window): Even when falling back on "recentering",
23556 position point in the window according to scroll-conservatively,
23557 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
23558
23559 (try_scrolling): When point is above the window, allow searching
23560 as far as scroll_max, or one screenful, to compute vertical
23561 distance from PT to the scroll margin position. This prevents
23562 try_scrolling from unnecessarily failing when
23563 scroll-conservatively is set to a value slightly larger than the
23564 window height. Clean up the case of PT below the margin at bottom
23565 of window: scroll_max can no longer be INT_MAX. When aggressive
23566 scrolling is in use, don't let point enter the opposite scroll
23567 margin as result of the scroll.
23568 (syms_of_xdisp) <scroll-conservatively>: Document the
23569 threshold of 100 lines for never-recentering scrolling.
23570
235712011-03-31 Juanma Barranquero <lekktu@gmail.com>
23572
23573 * dispextern.h (move_it_by_lines):
23574 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
23575 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
23576 (message_log_check_duplicate): Remove parameters `prev_bol' and
23577 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
23578 (redisplay_internal): Remove parameter `preserve_echo_area',
23579 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
23580
23581 * indent.c (Fvertical_motion):
23582 * window.c (window_scroll_pixel_based, Frecenter):
23583 Don't pass `need_y_p' to `move_it_by_lines'.
23584
235852011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
23586
23587 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
23588 steal a few bits to be more compact.
23589 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
23590 Remove unneeded casts.
23591
23592 * bytecode.c (Fbyte_code): CAR and CDR can GC.
23593
235942011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
23595
23596 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
23597 binding" message (bug#7967).
23598
235992011-03-30 Paul Eggert <eggert@cs.ucla.edu>
23600
23601 Fix more problems found by GCC 4.6.0's static checks.
23602
23603 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
23604 Remove unused local var.
23605
23606 * editfns.c (Fmessage_box): Remove unused local var.
23607
23608 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
23609 (note_mode_line_or_margin_highlight, note_mouse_highlight):
23610 Omit unused local vars.
23611 * window.c (shrink_windows): Omit unused local var.
23612 * menu.c (digest_single_submenu): Omit unused local var.
23613 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
23614 Omit unused local var.
23615
23616 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
23617 Don't assume string length fits in int.
23618 (keyremap_step, read_key_sequence): Use size_t for sizes.
23619 (read_key_sequence): Don't check last_real_key_start redundantly.
23620
23621 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
23622 instead of alloca (Bug#8344).
23623
23624 * eval.c (Fbacktrace): Don't assume nargs fits in int.
23625 (Fbacktrace_frame): Don't assume nframes fits in int.
23626
23627 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
23628
23629 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
23630 concerns.
23631
23632 * term.c (produce_glyphless_glyph): Remove unnecessary test.
23633
23634 * cm.c (calccost): Turn while-do into do-while, for clarity.
23635
23636 * keyboard.c (syms_of_keyboard): Use the same style as later
23637 in this function when indexing through an array. This also
23638 works around GCC bug 48267.
23639
23640 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
23641
23642 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
23643
23644 * chartab.c (sub_char_table_ref_and_range): Redo for slight
23645 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
23646
23647 * keyboard.c, keyboard.h (num_input_events): Now size_t.
23648 This avoids undefined behavior on integer overflow, and is a bit
23649 more convenient anyway since it is compared to a size_t variable.
23650
23651 Variadic C functions now count arguments with size_t, not int.
23652 This avoids an unnecessary limitation on 64-bit machines, which
23653 caused (substring ...) to crash on large vectors (Bug#8344).
23654 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.

23882
23883 Fix more problems found by GCC 4.5.2's static checks.
23884
23885 * coding.c (encode_coding_raw_text): Avoid unnecessary test
23886 the first time through the loop, since we know p0 < p1 then.
23887 This also avoids a gcc -Wstrict-overflow warning.
23888
23889 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
23890 leading to a memory leak, possible in functions like
23891 load_charset_map_from_file that can allocate an unbounded number
23892 of objects (Bug#8318).
23893
23894 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
23895 that could (at least in theory) be that large.
23896
23897 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
23898 This is less likely to overflow, and avoids undefined behavior if
23899 overflow does occur. All callers changed. Use strtoul to scan
23900 for the unsigned long integer.
23901 (pint2hrstr): Simplify and tune code slightly.
23902 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
23903

23916
23917 * process.c (Fmake_network_process): Use socklen_t, not int,
23918 where POSIX says socklen_t is required in portable programs.
23919 This fixes a porting bug on hosts like 64-bit HP-UX, where
23920 socklen_t is wider than int (Bug#8277).
23921 (Fmake_network_process, server_accept_connection):
23922 (wait_reading_process_output, read_process_output):
23923 Likewise.

23932 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
23933 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
23934
23935 Make tparam.h and terminfo.c consistent.
23936 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
23937 Include tparam.h instead, since it declares them.
23938 * cm.h (PC): Remove extern decl; tparam.h now does this.
23939 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
23940 * terminfo.c: Include tparam.h, to check interfaces.
23941 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
23942 (tparam): Adjust signature to match interface in tparam.h;
23943 this removes some undefined behavior. Check that outstring and len
23944 are zero, which they always are with Emacs.
23945 * tparam.h (PC, BC, UP): New extern decls.
23946
23947 * xftfont.c (xftfont_shape): Now static, and defined only if needed.

23957
23958 * xfont.c (xfont_list_family): Mark var as initialized.
23959
23960 * xml.c (make_dom): Now static.
23961
23962 * composite.c (composition_compute_stop_pos): Rename local to
23963 avoid shadowing.
23964 (composition_reseat_it): Remove unused locals.
23965 (find_automatic_composition, composition_adjust_point): Likewise.
23966 (composition_update_it): Mark var as initialized.
23967 (find_automatic_composition): Mark vars as initialized,
23968 with a FIXME (Bug#8290).
23969
23970 character.h: Rename locals to avoid shadowing.
23971 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
23972 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):

23975 to avoid shadowing.
23976

23978
23979 * intervals.c (interval_start_pos): Now static.
23980
23981 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
23982
23983 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
23984 Rename locals to avoid shadowing.
23985
23986 * sound.c (wav_play, au_play, Fplay_sound_internal):
23987 Fix pointer signedness.
23988 (alsa_choose_format): Remove unused local var.
23989 (wav_play): Initialize a variable to 0, to prevent undefined
23990 behavior (Bug#8278).
23991
23992 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
23993
23994 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
23995
23996 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
23997 clobbering (Bug#8298).
23998 * sysdep.c (sys_subshell): Likewise.
23999 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
24000
24001 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
24002 This should get cleaned up, so that child_setup has the
24003 same signature on all platforms.
24004
24005 * callproc.c (call_process_cleanup): Now static.
24006 (relocate_fd): Rename locals to avoid shadowing.

240082011-03-22 Chong Yidong <cyd@stupidchicken.com>
24009
24010 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
24011 not to be necessary, and produces flickering.

24020 are now in src/globals.h.
24021 (syms_of_minibuf): Remove spurious & from previous change.
24022
240232011-03-20 Leo Liu <sdl.web@gmail.com>

24095 warning when compiling print.c.
24096

24135 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
24136 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
24137 some of which prompt warnings from gcc -Wbad-function-cast.
24138 (Fformat_time_string, Fencode_time, Finsert_char):
24139 (Ftranslate_region_internal, Fformat):
24140 Rename or remove local vars to avoid shadowing.
24141 (Ftranslate_region_internal): Mark var as initialized.
24142

24147 ENABLE_CHECKING is not defined.
24148
24149 * data.c (Findirect_variable): Name an expression, to avoid

24161 they're used.
24162 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if

24167 (Fmemory_limit): Cast sbrk's returned value to char *.
24168

24171
24172 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
24173
24174 Use functions, not macros, for up- and down-casing (Bug#8254).
24175 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
24176 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
24177 to use the following functions instead of these macros.
24178 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
24179 EMACS_INT, since callers assume the returned value fits in int.
24180 (upcase1): Likewise, for UPCASE_TABLE.
24181 (uppercasep, lowercasep, upcase): New static inline functions.
24182 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

24188 (regex_compile, re_search_2, re_match_2_internal):
24189 Remove unused local vars.

24191 which gcc can warn about.
24192 (regex_compile, re_match_2_internal): Mark locals as initialized.
24193 (RETALLOC_IF): Define only if needed.
24194 (WORDCHAR_P): Likewise. This one is never needed, but is used
24195 only in a comment talking about a compiler bug, so put inside
24196 the #if 0 of that comment.
24197 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
24198 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
24199 Remove; unused.

24210
24211 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
24212
24213 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
24214 All uses changed.
24215 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
24216 Rename locals to avoid shadowing.
24217 (Fvertical_motion): Mark locals as initialized.
24218
24219 * casefiddle.c (casify_object, casify_region): Now static.
24220 (casify_region): Mark local as initialized.
24221
24222 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
24223
24224 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
24225 New macros, so that the caller can use some names other than
24226 gcpro1, gcpro2, etc.
24227 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
24228 of the new macros.
24229 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
24230 argument, for consistency with GCPRO2_VAR, etc: it is now the
24231 prefix of the variable, not the variable itself. All uses
24232 changed.
24233 * dired.c (directory_files_internal, file_name_completion):
24234 Rename locals to avoid shadowing.
24235
24236 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
24237 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
24238 dired.c's scmp function, had undefined behavior.
24239 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
24240 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
24241 * buffer.h: ... to here, because these macros use current_buffer,
24242 and the new implementation with inline functions needs to have
24243 current_buffer in scope now, rather than later when the macros
24244 are used.
24245 (downcase, upcase1): New static inline functions.
24246 (DOWNCASE, UPCASE1): Reimplement using these functions.
24247 This avoids undefined behavior in expressions like
24248 DOWNCASE (x) == DOWNCASE (y), which previously suffered
24249 from race conditions in accessing the global variables
24250 case_temp1 and case_temp2.
24251 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
24252 * lisp.h (case_temp1, case_temp2): Remove their decls.
24253 * character.h (ASCII_CHAR_P): Move from here ...
24254 * lisp.h: ... to here, so that the inline functions mentioned
24255 above can use them.
24256
24257 * dired.c (directory_files_internal_unwind): Now static.
24258
24259 * fileio.c (file_name_as_directory, directory_file_name):
24260 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
24261 Now static.
24262 (file_name_as_directory): Use const pointers when appropriate.
24263 (Fexpand_file_name): Likewise. In particular, newdir might
24264 point at constant storage, so make it a const pointer.
24265 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
24266 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
24267 signedness issues.
24268 (Fset_file_times, Finsert_file_contents, auto_save_error):
24269 Rename locals to avoid shadowing.
24270
24271 * minibuf.c (choose_minibuf_frame_1): Now static.
24272 (Ftry_completion, Fall_completions): Rename or remove locals
24273 to avoid shadowing.
24274
24275 * marker.c (bytepos_to_charpos): Remove; unused.
24276
24277 * lisp.h (verify_bytepos, count_markers): New decls,
24278 so that gcc does not warn that these functions aren't declared.
24279
24280 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
24281 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
24282 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
24283 (copy_text): Remove unused local var.
24284
24285 * filelock.c (within_one_second): Now static.
24286 (lock_file_1): Rename local to avoid shadowing.
24287
24288 * buffer.c (fix_overlays_before): Mark locals as initialized.
24289 (fix_start_end_in_overlays): Likewise. This function should be
24290 simplified by using pointers-to-pointers, but that's a different
24291 matter.
24292 (switch_to_buffer_1): Now static.
24293 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
24294 (report_overlay_modification): Rename locals to avoid shadowing.
24295
24296 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
24297 Fix pointer signedness issue.
24298 (sys_subshell): Mark local as volatile if checking for lint,
24299 to suppress a gcc -Wclobbered warning that does not seem to be right.
24300 (MAXPATHLEN): Define only if needed.
24301
24302 * process.c (serial_open, serial_configure): Move decls from here ...
24303 * systty.h: ... to here, so that they can be checked.
24304
24305 * fns.c (get_random, seed_random): Move extern decls from here ...
24306 * lisp.h: ... to here, so that they can be checked.
24307
24308 * sysdep.c (reset_io): Now static.
24309 (wait_for_termination_signal): Remove; unused.
24310
24311 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
24312 (copy_keymap_item, append_key, push_text_char_description):
24313 Now static.
24314 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
24315 (DENSE_TABLE_SIZE): Remove; unused.
24316 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
24317 (describe_map_tree):
24318 Rename locals to avoid shadowing.
24319
24320 * keyboard.c: Declare functions static if they are not used elsewhere.
24321 (echo_char, echo_dash, cmd_error, top_level_2):
24322 (poll_for_input, handle_async_input): Now static.

24331 * keyboard.h (make_ctrl_char): New decl.
24332 (mark_kboards): Move decl here ...
24333 * alloc.c (mark_kboards): ... from here.

24339 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
24340 Use it.
24341 (main): Add casts to avoid warnings
24342 if GCC considers string literals to be constants.
24343
24344 * lisp.h (fatal_error_signal): Add decl, since it's exported.
24345
24346 * dbusbind.c: Pointer signedness fixes.
24347 (xd_signature, xd_append_arg, xd_initialize):
