* Prefer HTTPS to FTP and HTTP in documentationPaul Eggert2017-09-131-2/+2
| | | | | | | | | | | | | Most of this change is to boilerplate commentary such as license URLs. This change was prompted by ftp://ftp.gnu.org's going-away party, planned for November. Change these FTP URLs to https://ftp.gnu.org instead. Make similar changes for URLs to other organizations moving away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and fsf.org when this works, as this will further help defend against man-in-the-middle attacks (for this part I omitted the MS-DOS and MS-Windows sources and the test tarballs to keep the workload down). HTTPS is not fully working to lists.gnu.org so I left those URLs alone for now.

| | | | | | | | | | | | * doc/lispref/display.texi (ImageMagick Images): Document :width/:max-height combinations (etc) (bug #25583). * src/image.c (compute_image_size): Handle :width/:max-height (etc) combinations consistently (by letting "max" win and preserve ratio). * test/manual/image-size-tests.el (image-size-tests): Add tests for :width/:max-height (etc) combinations.
* Add an optional testfn parameter to assocNicolas Petton2017-07-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | * src/fns.c (assoc): New optional testfn parameter used for comparison when provided. * test/src/fns-tests.el (test-assoc-testfn): Add tests for the new 'testfn' parameter. * src/buffer.c: * src/coding.c: * src/dbusbind.c: * src/font.c: * src/fontset.c: * src/gfilenotify.c: * src/image.c: * src/keymap.c: * src/process.c: * src/w32fns.c: * src/w32font.c: * src/w32notify.c: * src/w32term.c: * src/xdisp.c: * src/xfont.c: Add a third argument to Fassoc calls. * etc/NEWS: * doc/lispref/lists.texi: Document the new 'testfn' parameter.
* Check for integer overflow in xbm imagesPaul Eggert2017-07-051-7/+16
| | | | | | * src/image.c (XBM_TK_OVERFLOW): New constant. (xbm_scan): Check for integer overflow instead of relying on undefined behavior. Check that octal digits are actually octal.
* Convert hex digits more systematicallyPaul Eggert2017-07-051-7/+2
| | | | | | | | | | | | | | | | | This makes the code a bit smaller and presumably faster, as it substitutes a single lookup for conditional jumps. * src/character.c (hexdigit): New constant. (syms_of_character) [HEXDIGIT_IS_CONST]: Initialize it. * src/character.h (HEXDIGIT_CONST, HEXDIGIT_IS_CONST): New macros. (hexdigit): New decl. (char_hexdigit): New inline function. * src/charset.c: Do not include c-ctype.h. * src/charset.c (read_hex): * src/editfns.c (styled_format): * src/image.c (xbm_scan): * src/lread.c (read_escape): * src/regex.c (ISXDIGIT) [emacs]: Use char_hexdigit insted of doing it by hand.
* Use unlocked stdio more systematicallyPaul Eggert2017-06-221-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This can improve performance significantly on stdio-bottlenecked code. E.g., make-docfile is 3x faster on my Fedora 25 x86-64 desktop. * admin/merge-gnulib (GNULIB_MODULES): Add unlocked-io. * lib-src/ebrowse.c, lib-src/emacsclient.c, lib-src/etags.c: * lib-src/hexl.c, lib-src/make-docfile.c, lib-src/movemail.c: * lib-src/profile.c, lib-src/update-game-score.c: Include unlocked-io.h instead of stdio.h, since these programs are single-threaded. * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate. * lib/unlocked-io.h, m4/unlocked-io.m4: New files, copied from Gnulib. * src/charset.c, src/cm.c, src/emacs.c, src/image.c, src/keyboard.c: * src/lread.c, src/term.c: Include sysstdio.h, possibly instead of stdio.h, to define the unlocked functions if the system does not provide them. * src/charset.c, src/lread.c (getc_unlocked): Remove, since sysstdio.h now defines it if needed. * src/cm.c (cmputc, cmcheckmagic): * src/dispnew.c (update_frame, update_frame_with_menu) (update_frame_1, Fsend_string_to_terminal, Fding, bitch_at_user): * src/emacs.c (main, Fdump_emacs): * src/fileio.c (Fdo_auto_save, Fset_binary_mode): * src/image.c (slurp_file, png_read_from_file, png_load_body) (our_stdio_fill_input_buffer): * src/keyboard.c (record_char, kbd_buffer_get_event, handle_interrupt): * src/lread.c (readbyte_from_file): * src/minibuf.c (read_minibuf_noninteractive): * src/print.c (printchar_to_stream, strout) (Fredirect_debugging_output): * src/sysdep.c (reset_sys_modes, procfs_ttyname) (procfs_get_total_memory): * src/term.c (tty_ring_bell, tty_send_additional_strings) (tty_set_terminal_modes, tty_reset_terminal_modes) (tty_update_end, tty_clear_end_of_line, tty_write_glyphs) (tty_write_glyphs_with_face, tty_insert_glyphs) (tty_menu_activate): * src/xfaces.c (Fx_load_color_file): Use unlocked stdio when it should be safe. * src/sysstdio.h (clearerr_unlocked, feof_unlocked, ferror_unlocked) (fflush_unlocked, fgets_unlocked, fputc_unlocked, fputs_unlocked) (fread_unlocked, fwrite_unlocked, getc_unlocked, getchar_unlocked) (putc_unlocked, putchar_unloced): Provide substitutes if not declared.
* Avoid compiler warning in image.c on MS-WindowsEli Zaretskii2017-06-141-0/+10
| | | | | | * src/image.c (x_create_x_image_and_pixmap) [HAVE_NTGUI]: Avoid compilation warning under -Warray-bounds by temporarily disabling the -Warray-bounds option.
* Fix another compiler warning on macOSPhilipp Stephani2017-06-091-3/+2
| | | | | * src/image.c (x_query_frame_background_color): Don't define if we have NextStep but no image support.
* Restore XFLOATINT but with restricted argsPaul Eggert2017-03-021-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | Turn instances of extract_float into XFLOAT_DATA when possible, and to a resurrected XFLOATINT when the arg is a number. The resurrected XFLOATINT is more like XFLOAT and XINT in that is valid only if its arg is a number. This clarifies the ways in which floats can be extracted at the C level. * src/editfns.c (styled_format): * src/floatfns.c (extract_float, Fexpt): Use XFLOATINT rather than open-coding it. * src/fns.c (internal_equal): * src/image.c (imagemagick_load_image): * src/xdisp.c (resize_mini_window): Prefer XFLOAT_DATA to extract_float on values known to be floats. * src/frame.c (x_set_screen_gamma): * src/frame.h (NUMVAL): * src/image.c (x_edge_detection, compute_image_size): * src/lread.c (read_filtered_event): * src/window.c (Fset_window_vscroll): * src/xdisp.c (handle_single_display_spec, try_scrolling) (redisplay_window, calc_pixel_width_or_height, x_produce_glyphs) (on_hot_spot_p): Prefer XFLOATINT to extract_float on values known to be numbers. * src/lisp.h (XFLOATINT): Bring back this function, except it now assumes its argument is a number.
* Remove XFLOATINTPaul Eggert2017-03-021-3/+3
| | | | | | * src/lisp.h (XFLOATINT): Remove this alias for extract_float. All callers changed to use extract_float. * src/frame.h (NUMVAL): Now an inline function, not a macro.
* Use float instead of Lisp_Object for rehash_sizePaul Eggert2017-02-211-3/+2
| | | | | | | | | | | | | | | | | | * src/alloc.c (purecopy_hash_table): * src/fns.c (maybe_resize_hash_table, Fmake_hash_table): (Fhash_table_rehash_size): * src/lisp.h (struct Lisp_Hash_Table.rehash_size): The rehash_size member of struct Lisp_Hash_Table is now a float, not a Lisp_Object. * src/alloc.c (purecopy_hash_table): Assign members in order. * src/fns.c (make_hash_table): Use EMACS_INT for size and float for rehash_size, instead of Lisp_Object for both. All callers changed. * src/lisp.h (DEFAULT_REHASH_SIZE): Now float, not double, and 1 smaller. * src/print.c (print_object): Simplify by calling Fhash_table_rehash_size and Fhash_table_rehash_threshold. Avoid unnecessary NILP.
* Avoid aborts during loadupEli Zaretskii2017-02-191-2/+2
| | | | | | | | * src/emacs-module.c (syms_of_module): * src/image.c (xpm_make_color_table_h): Update calls to make_hash_table to adjust to a recent change in fns.c. * src/fns.c (make_hash_table): * src/lisp.h (make_hash_table): 4th arg is now of type double.
* Fix handling of XBM images on MS-WindowsEli Zaretskii2017-02-111-2/+2
| | | | | * src/image.c (xbm_load) [HAVE_NTGUI]: Fix calculation of 'nbytes' when inverting XBM data bits. (Bug#25661)
* Fix handling of PBM dataEli Zaretskii2017-02-111-1/+11
| | | | | * src/image.c (pbm_load): Handle PBM data with no blanks between individual pixel values correctly. (Bug#25660)
* Fix hash tables not being purified correctly.Vibhav Pant2017-01-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | * src/alloc.c (purecopy_hash_table) New function, makes a copy of the given hash table in pure storage. Add new struct `pinned_object' and `pinned_objects' linked list for pinning objects. (Fpurecopy) Allow purifying hash tables (purecopy) Pin hash tables that are either weak or not declared with `:purecopy t`, use purecopy_hash_table otherwise. (marked_pinned_objects) New function, marks all objects in pinned_objects. (garbage_collect_1) Use it. Mark all pinned objects before sweeping. * src/lisp.h Add new field `pure' to struct `Lisp_Hash_Table'. * src/fns.c: Add `purecopy' parameter to hash tables. (Fmake_hash_table): Check for a `:purecopy PURECOPY' argument, pass it to make_hash_table. (make_hash_table): Add `pure' parameter, set h->pure to it. (Fclrhash, Fremhash, Fputhash): Enforce that the table is impure with CHECK_IMPURE. * src/lread.c: (read1) Parse for `purecopy' parameter while reading hash tables. * src/print.c: (print_object) add the `purecopy' parameter while printing hash tables. * src/category.c, src/emacs-module.c, src/image.c, src/profiler.c, src/xterm.c: Use new (make_hash_table).

* | Reorder lisp.h to declare types before using themPaul Eggert2016-12-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This puts basic functions for types to be after the corresponding type definitions. This is a more-common programming style in C, and will make it easier to port Emacs to gcc -fcheck-pointer-bounds, since the functions now have access to the corresponding types' sizes. This patch does not change the code; it just moves declarations and definitions and removes no-longer-needed forward declarations (Bug#25128). * src/buffer.c, src/data.c, src/image.c: Include process.h, for PROCESSP. * src/buffer.h (BUFFERP, CHECK_BUFFER, XBUFFER): * src/process.h (PROCESSP, CHECK_PROCESS, XPROCESS): * src/termhooks.h (TERMINALP, XTERMINAL): * src/window.h (WINDOWP, CHECK_WINDOW, XWINDOW): * src/thread.h (THREADP, CHECK_THREAD, XTHREAD, MUTEXP, CHECK_MUTEX) (XMUTEX, CONDVARP, CHECK_CONDVAR, XCONDVAR): Move here from lisp.h. * src/intervals.h: Include buffer.h, for BUFFERP. Include lisp.h, for Lisp_Object. * src/lisp.h: Reorder declarations and definitions as described above. Move thread includes to be later, so that they can use the reordered definitions. Move some symbols to other headers (noted elsewhere). Remove forward decls that are no longer needed. * src/thread.h: Include systhread.h here, not in lisp.h, since lisp.h itself does not need systhread.h.
* | Simplify FUNCTIONP implementationPaul Eggert2016-12-061-1/+1
| | | | | | | | | | | | | | | | | | | | * src/bytecode.c (exec_byte_code): * src/image.c (parse_image_spec): Prefer FUNCTIONP (x) to !NILP (Ffunctionp (x)). * src/eval.c (FUNCTIONP): Move here ... * src/lisp.h: ... from here. No longer inline, as that bloats the text and does not help speed (at least on my platform). (functionp): Remove this name, since callers use FUNCTIONP.
* | Support for rawrgb images using imagemagickEvgeny Zajcev2016-12-021-0/+8
| | | | | | | | | | | | | | * src/image.c (imagemagick_load_image): Set wand size before loading blob when ':width' and ':height' are provided. * lisp/image.el (image-format-suffixes): Add 'image/x-rgb'.
* | Make Cairo safer for --enable-gcc-warningsPaul Eggert2016-12-011-26/+21
| | | | | | | | | | | | | | * src/image.c (xcolor_to_argb32, pbm_load, jpeg_load_body, gif_load): Avoid overflow warnings about ‘0xff << 24’. (xpm_load, gif_load): Avoid unnecessary casts. (gif_load): Fewer ifdefs.
* | Make CANNOT_DUMP work better on GNU/LinuxPaul Eggert2016-11-201-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clean up some of the bitrot affecting the CANNOT_DUMP code. This lets the build succeed again, and fixes the testing framework so that most test cases now pass. About twenty test cases still fail, though, and we still have Bug#24974. * configure.ac (CANNOT_DUMP): Now empty if CANNOT_DUMP. (SYSTEM_MALLOC): Now true if CANNOT_DUMP. There should no longer be any point to messing with a private memory allocator unless Emacs is dumping. * src/alloc.c (alloc_unexec_pre, alloc_unexec_post, check_pure_size): * src/image.c (reset_image_types): * src/lastfile.c (my_endbss, _my_endbss, my_endbss_static): Do not define if CANNOT_DUMP. * src/emacs.c (might_dump) [CANNOT_DUMP]: Now always false and local. (daemon_pipe) [!WINDOWSNT]: Now static. * test/Makefile.in (mostlyclean): Remove *.tmp files. (make-test-deps.mk): Elide CANNOT_DUMP chatter.

* | Port flexible array members to GCC + valgrindPaul Eggert2016-09-071-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These changes are needed to conform to the C standard's rule for allocating structs containing flexible array members. C11 says that malloc (offsetof (struct s, m) + n) does not suffice to allocate a struct with an n-byte tail; instead, malloc’s arg should be rounded up to the nearest multiple of alignof (struct s). Although this is arguably a defect in C11, gcc -O2 + valgrind sometimes complains when this rule is violated, and when debugging it’s better to keep valgrind happy. For details please see the thread containing the message at: https://gcc.gnu.org/ml/gcc-patches/2016-09/msg00416.html * lib-src/ebrowse.c, src/alloc.c, src/image.c, src/process.c: Include flexmember.h. * lib-src/ebrowse.c (add_sym, add_member, make_namespace) (register_namespace_alias): * src/alloc.c (SDATA_SIZE, allocate_string_data): * src/image.c (xpm_cache_color, imagemagick_create_cache): * src/process.c (Fmake_network_process): Use FLEXSIZEOF instead of offsetof and addition. * src/alloc.c (SDATA_SIZE, vector_alignment): Use FLEXALIGNOF instead of sizeof (ptrdiff_t). * src/lisp.h (ALIGNOF_STRUCT_LISP_VECTOR): Remove, as alloc.c can now calculate this on its own.

(FACE_SUITABLE_FOR_ASCII_CHAR_P, FACE_FOR_CHAR): Now inline functions instead of macros. This avoids the need for all those casts to void. (FACE_SUITABLE_FOR_ASCII_CHAR_P): Omit 2nd (unused) arg. All uses changed. * src/frame.c (Ficonify_frame, Fset_frame_position): * src/xdisp.c (Fmove_point_visually, show_mouse_face): * src/xdisp.c (note_mode_line_or_margin_highlight) (note_mouse_highlight): Assume HAVE_WINDOW_SYSTEM for simplicity, since the code should now work either way without generating warnings. * src/frame.c (display_available) [HAVE_WINDOW_SYSTEM]: New function. (window_system_available) [HAVE_WINDOW_SYSTEM]: Move to frame.h. (decode_window_system_frame): Use check_window_system instead of rolling the code ourself. Return needed only if HAVE_WINDOW_SYSTEM. (decode_window_system_frame, check_window_system): Merge the HAVE_WINDOW_SYSTEM and !HAVE_WINDOW_SYSTEM versions into one. * src/frame.c (Ficonify_frame, Fset_frame_position): * src/xdisp.c (show_mouse_face, define_frame_cursor1) (note_mouse_highlight): Narrow the scope of the HAVE_WINDOW_SYSTEM #ifdef; this is a better way to pacify GCC. * src/xdisp.c (x_set_left_fringe, x_set_right_fringe) (x_set_right_divider_width, x_set_bottom_divider_width): * src/xfns.c (x_set_internal_border_width): Don’t use what are now function calls as lvalues. * src/frame.h (WINDOW_SYSTEM_RETURN): New macro. (decode_window_system_frame, check_window_system): Use it, to avoid the need for duplicate declarations. (window_system_available): Now an inline function. (display_available): New decl.

(FRAME_FRINGE_COLS, FRAME_LEFT_FRINGE_WIDTH) (FRAME_RIGHT_FRINGE_WIDTH, FRAME_TOTAL_FRINGE_WIDTH) (FRAME_INTERNAL_BORDER_WIDTH, FRAME_RIGHT_DIVIDER_WIDTH) (FRAME_BOTTOM_DIVIDER_WIDTH): Use it, to avoid the need for duplicate definitions. Now inline functions instead of macros. * src/gnutls.c (gnutls_log_function2i): Remove. * src/gnutls.h (GNUTLS_LOG2i): Use ‘message’ directly. This avoids complaints about gnutls_log_function2i being defined and not used on older platforms that do not need to call GNUTLS_LOG2i. * src/image.c (DefaultDepthOfScreen) [0]: Remove unused macro. * src/lisp.h (AUTO_STRING_WITH_LEN): Revert change from ‘type id = expr’ to ‘type id; id = expr’, as this would suppress valid jump-misses-init diagnostics. Let’s find a better way to address the problem. * src/vm-limit.c (__MALLOC_HOOK_VOLATILE): Define only if needed. * src/xdisp.c (handle_single_display_spec): Simplify fringe_bitmap computation. (define_frame_cursor1): Do nothing unless in a window system. All callers changed and simplified. * src/xfaces.c (realize_default_face): Use a simpler way to pacify GCC when a return value is not used on some platforms.

| * Rework C source files to avoid ^(Paul Eggert2016-03-101-2/+2
| | | | | | | | | | | | | | | | Work around Bug#22884 by rewording comments and strings to avoid ‘(’ at the start of a line unless it starts a function. This change is a short-term hack; in the longer run we plan to fix cc-mode’s performance for C files that have ‘(’ at the start of a line in a comment or string.
