+        * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:

+2013-02-15  Eli Zaretskii  <eliz@gnu.org>
+
+        * w32proc.c (new_child): If no vacant slots are found in

+2013-02-14  Stefan Monnier  <monnier@iro.umontreal.ca>
+
+        * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not

+
+2013-02-13  Glenn Morris  <rgm@gnu.org>
+
+        * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
+
+2013-02-13  Paul Eggert  <eggert@cs.ucla.edu>
+
+        Improve AIX port some more (Bug#13650).
+        With this, it should be as good as it was in 23.3, though it's
+        still pretty bad: the dumped emacs does not run.  See Mark Fleishman in
+        http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
+        * unexaix.c (start_of_text): Remove.
+        (_data, _text): Declare as char[], not int, as AIX manual suggests.
+        (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
+        (orig_load_scnptr, orig_data_scnptr):
+        Now off_t, not long, since they are file offsets.
+        (make_hdr): Use _data, not start_of_data ().
+        This is the key part of the fix.
+        (make_hdr, unrelocate_symbols): Use off_t for file offsets.
+        (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
+
+        * pre-crt0.c (data_start): Initialize to 1.
+        This ports to compilers that optimize the external declaration
+        'int x = 0;' as if it were 'int x;' to shrink the executable.
+
+        Improve AIX port (Bug#13650).
+        This doesn't fix the bug, but it makes progress: Emacs builds now.
+        * unexaix.c: Include inttypes.h, stdarg.h.
+        (report_error, report_error_1): Mark as _Noreturn.
+        (report_error): Don't report the wrong errno.
+        (report_error_1): Now varargs.  All callers changed.
+        (make_hdr): Use uintptr_t, not unsigned, when converting pointers
+        to unsigned.  Don't use ADDR_CORRECT, as it no longer exists.
+        (write_ptr): Use %p to print address rather than %lx and a cast
+        to unsigned long.  Grow buffer a bit, to be safer.
+
+2013-02-13  Eli Zaretskii  <eliz@gnu.org>
+
+        * bidi.c (bidi_resolve_neutral): After finding the next
+        non-neutral character, accept NEUTRAL_ON type as well, because
+        directional control characters, such as LRE and RLE, have their
+        type converted to that by bidi_resolve_weak.  This avoids aborts
+        when LRE/RLE follows a run of neutrals.
+        (bidi_move_to_visually_next): Assert that return value of
+        bidi_peek_at_next_level is non-negative.  Negative values will
+        cause an infloop.
+
+2013-02-13  Paul Eggert  <eggert@cs.ucla.edu>
+
+        Minor getenv-related fixes.
+        * callproc.c (Fcall_process_region) [!DOS_NT]:
+        Avoid unnecessary duplicate call to getenv.
+        * callproc.c (init_callproc):
+        * dispnew.c (init_display):
+        * sysdep.c (sys_subshell):
+        Omit unnecessary cast of getenv or egetenv.
+
+2013-02-13  Juanma Barranquero  <lekktu@gmail.com>
+
+        * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
+        Update dependencies.
+
+2013-02-12  Eli Zaretskii  <eliz@gnu.org>
+
+        * xdisp.c (redisplay_internal): Don't set w->region_showing to the
+        marker's position.
+        (display_line): Set w->region_showing to the value of
+        it->region_beg_charpos, not to -1.  This fixes redisplay
+        optimization when cursor is moved up after M->.  (Bug#13623)
+        (Bug#13626)
+        (try_scrolling): Scroll text up more if point is too close to ZV
+        and inside the scroll margin.  This makes sure point is moved
+        outside the scroll margin in these cases.
+
+        * window.h (struct window): region_showing can no longer be
+        negative.
+
+2013-02-11  Paul Eggert  <eggert@cs.ucla.edu>
+
+        Tune by using memchr and memrchr.
+        * doc.c (Fsnarf_documentation):
+        * fileio.c (Fsubstitute_in_file_name):
+        * search.c (find_newline, scan_newline):
+        * xdisp.c (pos_visible_p, display_count_lines):
+        Use memchr and memrchr rather than scanning byte-by-byte.
+        * search.c (find_newline): Rename from scan_buffer.
+        Omit first arg TARGET, as it's always '\n'.  All callers changed.
+
+        Clean up read_key_sequence a tiny bit more.
+        * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
+        (read_key_sequence): Remove unused locals.
+
+2013-02-11  Stefan Monnier  <monnier@iro.umontreal.ca>
+
+        Clean up read_key_sequence a bit; reread active keymaps after first event.
+        * keyboard.c (read_char, read_char_x_menu_prompt)
+        (read_char_minibuf_menu_prompt):
+        Replace nmaps+maps with a single `map' arg.
+        (follow_key): Operate on a single map.
+        (active_maps): New function.
+        (test_undefined): Also return true for nil bindings.
+        (read_key_sequence): Use active_maps to replace the arrays of keymaps with
+        a single (composed) keymap.  Remember `first_event' to choose the right
+        set of active keymaps.  Recompute the set of keymaps after receiving
+        the first event.  Remove GOBBLE_FIRST_EVENT.
+        (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
+        * keyboard.h (read_char): Update declaration.
+        * lread.c (read_filtered_event): Adjust call to read_char.
+
+2013-02-11  Eli Zaretskii  <eliz@gnu.org>
+
+        * xdisp.c (move_it_vertically_backward, move_it_by_lines):
+        Don't use the limitation on backwards movement when lines are truncated
+        in the window.  (Bug#13675)
+
+2013-02-11  Dmitry Antipov  <dmantipov@yandex.ru>
+
+        * marker.c (set_marker_internal): If desired position is passed
+        as a marker, avoid call to buf_charpos_to_bytepos.
+        * window.c (Fset_window_point): Omit redundant type checking.
+        (Fset_window_start): Likewise.  Format comment.
+        (window_scroll_pixel_based): Use set_marker_restricted_both
+        with character and byte positions obtained from an iterator.
+        (Fset_window_configuration): Use set_marker_restricted_both.
+        * xdisp.c (message_dolog): Likewise.
+
+2013-02-10  Eli Zaretskii  <eliz@gnu.org>
+
+        * xdisp.c (move_it_vertically_backward, move_it_by_lines):
+        When text lines are longer than window's screen lines, don't move back
+        too far.  This speeds up some redisplay operations.  (Bug#13675)
+
+2013-02-10  Dmitry Antipov  <dmantipov@yandex.ru>
+
+        * syntax.c (scan_sexps_forward): Fix byte position calculation
+        Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
+
+2013-02-10  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
+        that was not needed.
+
+2013-02-09  Paul Eggert  <eggert@cs.ucla.edu>
+
+        Minor hashing refactoring.
+        * fns.c (SXHASH_REDUCE): Move to lisp.h.
+        (sxhash_float): Return EMACS_UINT, for consistency with the other
+        hash functions.
+        * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
+        non-static inline function and therefore can't use static vars.
+        (SXHASH_REDUCE): Move here from fns.c, and make it inline.
+        * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
+        with the other hash functions.
+
+2013-02-09  Eli Zaretskii  <eliz@gnu.org>
+
+        * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
+        XXXXXX part of the temporary file pattern is not downcased even
+        when w32-downcase-file-names is non-nil.  (Bug#13661)
+
+        * xdisp.c (decode_mode_spec): Remove handling of %t.
+
+        * msdos.c (careadlinkatcwd): Remove.
+
+2013-02-08  Stefan Monnier  <monnier@iro.umontreal.ca>
+
+        * lread.c (skip_dyn_bytes): New function (bug#12598).
+        (read1): Use it.  Use getc instead of READCHAR to read bytes.
+        (load_each_byte): Remove.  Update users.
+
+2013-02-08  Dmitry Antipov  <dmantipov@yandex.ru>

+        character to byte position calculation ...
+        (Fparse_partial_sexp): ... here.  Break too long line.

+
+2013-02-04  Eli Zaretskii  <eliz@gnu.org>
+
+        * xdisp.c (window_buffer_changed): region_showing can be negative,
+        which still means region is being displayed.
+        (redisplay_internal): Resurrect code that forced redisplay of the
+        whole window when showing region and the mark has changed.
+        Record the new mark position to allow redisplay optimizations.
+        (display_line): If it->region_beg_charpos is non-zero, set the

+
+        * window.h (struct window) <region_showing>: Declare ptrdiff_t,

+
+        Avoid file time stamp bug on MS-Windows (Bug#13149).
+        * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
+        as FAT32 doesn't update time stamps when truncating them.
+        Also, check that a file time stamp is not a multiple of 100 ns;
+        this should catch all instances of the problem on MS-Windows,
+        as its native file system resolution is 100 ns or worse, and
+        checking for a non-multiple of 100 ns should impose only a small
+        overhead on systems with ns resolution.

+        Avoid encoding file names on MS-Windows when they need to be run

+        * w32.c (normalize_filename): Accept an additional argument

+
+        Fix timestamp bug when write-region appends nothing (Bug#13149).
+        * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
+        the file's time stamp doesn't change if Emacs happens to write nothing
+        to the file, and on a buggy file system this could cause Emacs to

+
+        * fileio.c: Use O_APPEND to append.
+        This corresponds better to the natural interpretation of "append",
+        and avoids the need to open the output file twice, or to invoke

+        This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
+        (Fwrite_region): Simplify.  Use O_APPEND instead of opening the
+        file possibly twice, and lseeking to its end; this avoids the
+        need to lseek on non-regular files.  Do not use O_EXCL and O_TRUNC
+        at the same time: the combination is never needed and apparently
+        it doesn't work with DOS_NT.
+
+        Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).

+2012-12-27  Eli Zaretskii  <eliz@gnu.org>
+
+        * fileio.c (file_name_as_directory, directory_file_name):
+        Accept an additional argument MULTIBYTE to indicate whether the input C
+        came from a multibyte or a unibyte Lisp string; all callers
+        adjusted.  Don't assume the input string is always multibyte.
+        (Bug#13262)
+        (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
+        don't ENCODE_FILE them, and return a unibyte string if the input
+        was unibyte.
+        (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
+        don't assume the input strings will always be multibyte.  If the
+        input strings are multibyte, decode strings obtained from C
+        library functions.
+
+2012-12-26  Dmitry Antipov  <dmantipov@yandex.ru>
+
+        * lisp.h (toplevel): Add two notices to the comment about
+        defining a new Lisp data type.
+        * print.c (print_object): If Lisp_Save_Value object's pointer
+        is the address of a memory area containing Lisp_Objects, try
+        to print them.
+        * alloc.c (valid_lisp_object_p): Adjust comment.
+
+2012-12-26  Dmitry Antipov  <dmantipov@yandex.ru>

+        * frame.h (enum output_method): Remove output_mac member since
+        it's a leftover from the deleted code.
+        * frame.c (Fframep): Adjust user here ...
+        * terminal.c (Fterminal_live_p): ... and here.
+        * coding.c (Qmac): Now here because it's only used to denote
+        end-of-line encoding type.
+        (syms_of_coding): DEFSYM it.
+        * frame.h (Qmac): Remove duplicated declaration.
+
+2012-12-26  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * window.c (select_window_1): Now static, since it's used only here.
+
+2012-12-25  Eli Zaretskii  <eliz@gnu.org>
+
+        * window.c (window_body_cols): Subtract display margins from the
+        window body width on TTYs as well.  See
+        http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html

+
+2012-12-25  Dmitry Antipov  <dmantipov@yandex.ru>
+
+        * xdisp.c (redisplay_window): Remove inner local variable
+        because the outer shadowed one has the same meaning.
+        * xterm.h (struct x_output): Remove toolbar_detached member since it's
+        set but never used.
+        * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
+        (xg_create_tool_bar): Adjust users.
+
+2012-12-24  Dmitry Antipov  <dmantipov@yandex.ru>
+
+        * buffer.h (BUF_COMPACT): New macro to follow the common style.
+        * buffer.c (Fget_buffer_create): Use it to set compact field of
+        struct buffer_text to avoid accessing an uninitialized value
+        when compact_buffer is called for the first time.
+        (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
+        (Fset_buffer_modified_p): Use buffer_window_count to check
+        whether the buffer is displayed in some window.
+        * xdisp.c (message_dolog): Likewise.
+
+2012-12-23  Eli Zaretskii  <eliz@gnu.org>
+
+        * w32.c (acl_set_file): If setting the file security descriptor
+        fails, and the new DACL is identical to the existing one, silently
+        return success.  This fixes problems for users backing up their
+        own files without having the necessary privileges for setting
+        security descriptors.
+
+        * w32proc.c (reader_thread): Do not index fd_info[] with negative
+        values.
+        (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
+        after WaitForSingleObject returns normally.  This expedites reader
+        thread shutdown when delete_child triggers it.
+        (reap_subprocess): More accurate commentary for why we call
+        delete_child only when cp->fd is negative.
+
+        * w32.c (sys_close): Do not call delete_child on a subprocess
+        whose handle is not yet closed.  Instead, set its file descriptor
+        to a negative value, so that reap_subprocess will call
+        delete_child on that subprocess when its SIGCHLD arrives.
+        This avoids closing handles used for communications between sys_select
+        and reader_thread, which doesn't give sys_select a chance to
+        notice that the process exited and invoke the SIGCHLD handler for
+        it.
+
+2012-12-23  Jan Djärv  <jan.h.d@swipnet.se>
+
+        * nsfns.m (Fns_do_applescript): Run event loop until script has
+        been executed (Bug#12969).
+        (ns_run_ascript): Chech as_script for nil, set to nil after
+        executing script.
+
+2012-12-22  Martin Rudalics  <rudalics@gmx.at>
+
+        * window.c (Fselect_window): Reword doc-string (Bug#13248).
+
+2012-12-22  Eli Zaretskii  <eliz@gnu.org>
+
+        * w32term.c (w32fullscreen_hook): New function.
+        (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
+
+2012-12-21  Eli Zaretskii  <eliz@gnu.org>
+
+        * fileio.c (Finsert_file_contents): Doc fix.
+
+        * w32proc.c (new_child, delete_child, find_child_pid): For a
+        subprocess, consider its slot being in use as long as its process
+        handle (procinfo.hProcess) is not NULL.  This avoids reusing the
+        slot when a new process is started immediately after killing
+        another one, without waiting enough time for the first process to
+        be reaped and resources allocated for it be orderly freed.

+
+2012-12-21  Eli Zaretskii  <eliz@gnu.org>
+
+        * w32.c (get_name_and_id): Always pass NULL as the first argument
+        of lookup_account_sid.  Avoids crashes with UNC file names that
+        refer to DFS domains, not to specific machine names.  (Bug#12621)
+        Remove now unused argument FNAME; all callers changed.
+        (get_file_owner_and_group): Remove now unused argument FNAME; all
+        callers changed.
+
+2012-12-21  Chong Yidong  <cyd@gnu.org>
+
+        * editfns.c (Finsert_char): Since read-char-by-name now signals an
+        error for invalid chars, don't check for a nil return value.
+
+2012-12-20  Dmitry Antipov  <dmantipov@yandex.ru>
+
+        Avoid calls to CHAR_TO_BYTE if byte position is known.

+        (Fbuffer_string): Use make_buffer_string_both.
+        * marker.c (buf_charpos_to_bytepos): Convert to eassert.
+        Adjust comment.
+        (buf_bytepos_to_charpos): Likewise.

+
+2012-12-20  Paul Eggert  <eggert@cs.ucla.edu>

+
+        * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.

+
+2012-12-20  Dmitry Antipov  <dmantipov@yandex.ru>

+

+
+2012-12-18  Eli Zaretskii  <eliz@gnu.org>
+
+        * w32.c (acl_get_file, acl_set_file): Run the file name through

+        Posix platforms do.
+        (acl_set_file): Call revert_to_self, if any privileges were

+        Remove unnecessary S_ISLNK test, as (contra the comments) this
