48 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
49 from Elisp via unread-command-events.
51 * keyboard.c (access_keymap_keyremap): Accept nil return value from
52 functions to mean "no change".
54 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
56 region-cache.c, scroll.c, search.c: Use bool for booleans.
57 * lisp.h (compile_pattern):

105 to match other functions accepting character and byte positions.
107 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.

187 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
188 * sysdep.c (list_system_processes)
189 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
190 Make it a stub in this case; otherwise the build might fail,
191 and this code hasn't been tested on such hosts anyway.
192 Problem reported by Nelson H. F. Beebe in
193 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
194 and analyzed by Jérémie Courrèges-Anglas in

205 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
207 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
208 * filelock.c: Include <c-ctype.h>.
209 (MAX_LFINFO): New top-level constant.
210 (lock_info_type): Remove members pid, boot_time. Add members at,
211 dot, colon. Change user member to be the entire buffer, not a
212 pointer. This allows us to handle the case where a foreign
213 pid or boot time exceeds the local range. All uses changed.
214 (LINKS_MIGHT_NOT_WORK): New constant.
215 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
216 (defined_WINDOWSNT): Remove.
217 (MAKE_LOCK_NAME, file_in_lock_file_name):
218 Always use .#FILE (not .#-FILE) for the file lock,
219 even if it is a regular file.
220 (rename_lock_file): New function.
221 (create_lock_file): Use it.
222 (create_lock_file, read_lock_data):
223 Prefer a symbolic link for the lock file, falling back on a
224 regular file if symlinks don't work. Do not try to create
225 symlinks on MS-Windows, due to security hassles. Stick with
226 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
227 link, rename, unlink, mkstemp) when creating locks, as a GNUish
228 host may be using a Windowsish file system, and cannot use
229 MS-Windows-only system calls. Fall back on mktemp if mkstemp
230 doesn't work. Don't fail merely because of a symlink-contents
231 length limit in the current file system; fall back on regular
232 files. Increase the symlink contents length limit to 8 KiB, this
233 should be big enough for any real use and doesn't crunch the
235 (create_lock_file, lock_file_1, read_lock_data):
236 Simplify allocation of lock file buffers now that they fit in 8 KiB.
237 (lock_file_1): Return error number, not bool. All callers changed.
238 (ELOOP): New macro, if not already defined.
239 (read_lock_data): Return size of lock file contents, not Lisp object.
240 All callers changed. Handle a race condition if some other process
241 replaces a regular-file lock with a symlink lock or vice versa,
242 while we're trying to read the lock.
243 (current_lock_owner): Parse contents more carefully, to help avoid
244 confusing a regular-file lock with some other application's use
245 of the file. Check for lock file contents being too long, or
246 not parsing correctly.
247 (current_lock_owner, lock_file):
248 Allow foreign pid and boot times that exceed the local range.
249 (current_lock_owner, lock_if_free, lock_file):
250 Simplify allocation of lock file contents.
251 * w32.c (sys_rename_replace): New function, containing most of
252 the contents of the old sys_rename.
253 (sys_rename): Use it.
254 (fchmod): New dummy function.
255 * w32.h (sys_rename_replace, fchmod): New decls.
257 2013-03-05 Eli Zaretskii <eliz@gnu.org>
259 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
260 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
261 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
262 <dmantipov@yandex.ru>.
264 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
266 * composite.c (get_composition_id, fill_gstring_header):
267 Use make_uninit_vector where appropriate.
268 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
269 * xselect.c (clean_local_selection_data): Likewise.
271 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
273 Fix misuse of ImageMagick that caused core dump (Bug#13846).
274 * image.c (imagemagick_load_image): Calculate height and width
275 after flattening the image, not before.
277 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
279 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
280 * ftfont.c (ftfont_shape_by_flt): Likewise.
281 * w32uniscribe.c (uniscribe_shape): Likewise.
283 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
285 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
286 The old approach, which fell back on DIR/.#FILE.0 through
287 DIR/.#FILE.9, had race conditions that could not be easily fixed.
288 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
289 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
290 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
291 because the locking mechanism was never reliable in that case).
292 This patch fixes this and other bugs discovered by a code
293 inspection that was prompted by
294 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
295 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
296 to avoid interoperability problems between the MS-Windows and
297 non-MS-Windows implementations. MS-Windows and non-MS-Windows
298 instances of Emacs now ignore each others' locks.
299 * filelock.c (defined_WINDOWSNT): New constant.
300 (MAKE_LOCK_NAME, fill_in_lock_file_name):
301 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
302 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
303 regular files on MS-Windows hosts.
304 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
305 Use SAFE_ALLOCA to avoid problems with long file names.
306 (MAX_LFINFO): Now a local constant, not a global macro.
307 (IS_LOCK_FILE): Remove.
308 (lock_file_1): Don't inspect errno if symlink call succeeds;
310 (lock_file): Document that this function can return if lock
312 (lock_file): Don't access freed storage.
314 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>

318 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
320 * textprop.c: Use bool for booleans.
321 (validate_interval_range, Fadd_text_properties)
322 (Fremove_text_properties): Prefer bool to int when either works.
324 2013-03-02 Eli Zaretskii <eliz@gnu.org>
326 * textprop.c (Fadd_text_properties, Fremove_text_properties):
327 If the interval tree changes as a side effect of calling
328 modify_region, re-do processing starting from the call to
329 validate_interval_range. (Bug#13743)
331 2013-02-28 Eli Zaretskii <eliz@gnu.org>
333 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
336 2013-02-27 Eli Zaretskii <eliz@gnu.org>
338 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
339 _SH_DENYRW flag, instead of emacs_open, to deny any other process
340 access to the lock file until it is written and closed.
343 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
345 * callint.c (Qcall_interactively):
346 * macros.c (Qexecute_kbd_macro):
349 2013-02-26 Bastien Guerry <bzg@gnu.org>
351 * window.c (Frecenter): Tiny docstring enhancement.
353 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
355 Minor textprop integer cleanup.
356 * intervals.h, textprop.c (add_text_properties_from_list):
357 Return void, not int, since nobody uses the return value.
358 * textprop.c (validate_plist, add_properties, remove_properties)
359 (Fadd_text_properties):
360 Don't assume list length fits in int.
361 (interval_has_all_properties, interval_has_some_properties)
362 (interval_has_some_properties_list, add_properties, remove_properties)
363 (Fadd_text_properties, Fremove_text_properties)
364 (Fremove_list_of_text_properties, text_property_stickiness):
365 Use bool for booleans.
366 (Fadd_text_properties, Fremove_text_properties):
367 (Fremove_list_of_text_properties):
368 Reindent do-while as per GNU style.
370 2013-02-25 Eli Zaretskii <eliz@gnu.org>
372 Implement CLASH_DETECTION for MS-Windows.
374 * filelock.c [WINDOWSNT]: Include w32.h.
375 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
376 function of that name. Up-case the macro arguments.
377 (IS_LOCK_FILE): New macro.
378 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
379 (create_lock_file): New function, with body extracted from
381 [WINDOWSNT]: Implement lock files by writing a regular file with
382 the lock information as its contents.
383 (read_lock_data): New function, on Posix platforms just calls
385 [WINDOWSNT]: Read the lock info from the file.
386 (current_lock_owner): Call read_lock_data instead of calling
387 emacs_readlinkat directly.
388 (lock_file) [WINDOWSNT]: Run the file name through
391 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
392 just check if the process by that PID exists.
394 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
395 also present, as doing so will fail to error out if the file
398 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
400 * textprop.c (Fadd_text_properties, Fremove_text_properties)
401 (Fremove_list_of_text_properties): Skip all of the intervals in
402 the region between START and END that already have resp. don't
403 have the requested properties, not just the first one.
404 Add assertions that the loop afterwards always modifies the
405 properties. (Bug#13743)

484 (syms_of_keyboard): Adjust accordingly.
486 2013-02-19 Daniel Colascione <dancol@dancol.org>
488 * sheap.c (report_sheap_usage): Use message, not message1, so
489 that we don't try to create a buffer while we're in the middle
490 of dumping Emacs. Explain why.
492 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
494 * search.c (find_newline): Return byte position in bytepos.

504 (get_visually_first_element, move_it_vertically_backward):
505 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
507 2013-02-19 Eli Zaretskii <eliz@gnu.org>

514 * xdisp.c (x_draw_vertical_border): For a window that is neither
515 the leftmost nor the rightmost, redraw both the left and the right
516 vertical borders. (Bug#13723)

538 * w32.c (sys_chown): Remove unused function.
540 * w32term.c <input_signal_count>: Declare 'volatile'
541 unconditionally. (Bug#9066)
543 * w32.c (set_errno): Reset h_errno and don't set it to any other
544 value. Set errno instead.
545 (check_errno): Reset h_errno.

557 2013-02-15 Eli Zaretskii <eliz@gnu.org>
559 * keyboard.c (read_char): Fix calculation of auto-save time out
560 when auto-save-timeout is less than 4. (Bug#13720)
562 * w32proc.c (new_child): Free up to 2 slots of dead processes at a

571 value that is out of bounds.
572 (sys_accept): If fd is negative, do not set up the child_process
573 structure for reading.

589 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
591 Fix AIX port (Bug#13650).
592 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
593 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
594 was #undeffed earlier, so it cannot be used as a macro here.
595 Use the constant and not the macro.
597 2013-02-15 Eli Zaretskii <eliz@gnu.org>
599 * w32proc.c (new_child): If no vacant slots are found in
600 child_procs[], make another pass looking for slots whose process

607 STATUS_READ_IN_PROGRESS. (Bug#13546)
609 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
611 * gtkutil.c (tb_size_cb): New function.

631 2013-02-13 Glenn Morris <rgm@gnu.org>
633 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
635 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
637 Improve AIX port some more (Bug#13650).
638 With this, it should be as good as it was in 23.3, though it's
639 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
640 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
641 * unexaix.c (start_of_text): Remove.
642 (_data, _text): Declare as char[], not int, as AIX manual suggests.
643 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
644 (orig_load_scnptr, orig_data_scnptr):
645 Now off_t, not long, since they are file offsets.
646 (make_hdr): Use _data, not start_of_data ().
647 This is the key part of the fix.
648 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
649 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
651 * pre-crt0.c (data_start): Initialize to 1.
652 This ports to compilers that optimize the external declaration
653 'int x = 0;' as if it were 'int x;' to shrink the executable.
655 Improve AIX port (Bug#13650).
656 This doesn't fix the bug, but it makes progress: Emacs builds now.
657 * unexaix.c: Include inttypes.h, stdarg.h.
658 (report_error, report_error_1): Mark as _Noreturn.
659 (report_error): Don't report the wrong errno.
660 (report_error_1): Now varargs. All callers changed.
661 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
662 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
663 (write_ptr): Use %p to print address rather than %lx and a cast
664 to unsigned long. Grow buffer a bit, to be safer.
666 2013-02-13 Eli Zaretskii <eliz@gnu.org>
668 * bidi.c (bidi_resolve_neutral): After finding the next
669 non-neutral character, accept NEUTRAL_ON type as well, because
670 directional control characters, such as LRE and RLE, have their
671 type converted to that by bidi_resolve_weak. This avoids aborts
672 when LRE/RLE follows a run of neutrals.
673 (bidi_move_to_visually_next): Assert that return value of
674 bidi_peek_at_next_level is non-negative. Negative values will
677 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
679 Minor getenv-related fixes.
680 * callproc.c (Fcall_process_region) [!DOS_NT]:

682 * callproc.c (init_callproc):
683 * dispnew.c (init_display):
684 * sysdep.c (sys_subshell):
685 Omit unnecessary cast of getenv or egetenv.
687 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
689 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
692 2013-02-12 Eli Zaretskii <eliz@gnu.org>
694 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
696 (display_line): Set w->region_showing to the value of
697 it->region_beg_charpos, not to -1. This fixes redisplay
698 optimization when cursor is moved up after M->. (Bug#13623)
700 (try_scrolling): Scroll text up more if point is too close to ZV
701 and inside the scroll margin. This makes sure point is moved
702 outside the scroll margin in these cases.
704 * window.h (struct window): region_showing can no longer be
707 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
709 Tune by using memchr and memrchr.
710 * doc.c (Fsnarf_documentation):
711 * fileio.c (Fsubstitute_in_file_name):
712 * search.c (find_newline, scan_newline):
713 * xdisp.c (pos_visible_p, display_count_lines):
714 Use memchr and memrchr rather than scanning byte-by-byte.
715 * search.c (find_newline): Rename from scan_buffer.
716 Omit first arg TARGET, as it's always '\n'. All callers changed.
718 Clean up read_key_sequence a tiny bit more.
719 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
720 (read_key_sequence): Remove unused locals.
722 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
724 Clean up read_key_sequence a bit; reread active keymaps after first event.
725 * keyboard.c (read_char, read_char_x_menu_prompt)
726 (read_char_minibuf_menu_prompt):
727 Replace nmaps+maps with a single `map' arg.
728 (follow_key): Operate on a single map.
729 (active_maps): New function.
730 (test_undefined): Also return true for nil bindings.
731 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
732 a single (composed) keymap. Remember `first_event' to choose the right
733 set of active keymaps. Recompute the set of keymaps after receiving
734 the first event. Remove GOBBLE_FIRST_EVENT.
735 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
736 * keyboard.h (read_char): Update declaration.
737 * lread.c (read_filtered_event): Adjust call to read_char.
739 2013-02-11 Eli Zaretskii <eliz@gnu.org>
741 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
742 Don't use the limitation on backwards movement when lines are truncated
743 in the window. (Bug#13675)
745 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
747 * marker.c (set_marker_internal): If desired position is passed
748 as a marker, avoid call to buf_charpos_to_bytepos.
749 * window.c (Fset_window_point): Omit redundant type checking.
750 (Fset_window_start): Likewise. Format comment.
751 (window_scroll_pixel_based): Use set_marker_restricted_both
752 with character and byte positions obtained from an iterator.
753 (Fset_window_configuration): Use set_marker_restricted_both.
754 * xdisp.c (message_dolog): Likewise.
756 2013-02-10 Eli Zaretskii <eliz@gnu.org>
758 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
759 When text lines are longer than window's screen lines, don't move back
760 too far. This speeds up some redisplay operations. (Bug#13675)
762 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
764 * syntax.c (scan_sexps_forward): Fix byte position calculation
765 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
767 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
769 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
772 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
774 Minor hashing refactoring.
775 * fns.c (SXHASH_REDUCE): Move to lisp.h.
776 (sxhash_float): Return EMACS_UINT, for consistency with the other
778 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
779 non-static inline function and therefore can't use static vars.
780 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
781 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
782 with the other hash functions.
784 2013-02-09 Eli Zaretskii <eliz@gnu.org>
786 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
787 XXXXXX part of the temporary file pattern is not downcased even
788 when w32-downcase-file-names is non-nil. (Bug#13661)
790 * xdisp.c (decode_mode_spec): Remove handling of %t.
792 * msdos.c (careadlinkatcwd): Remove.
794 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
796 * lread.c (skip_dyn_bytes): New function (bug#12598).

800 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
802 * search.c (scan_buffer): Calculate end byte position just once.
803 (scan_newline): Do not recalculate start_byte.
804 (search_command): Use eassert.
805 * syntax.c (struct lisp_parse_state): New member location_byte.
806 (scan_sexps_forward): Record from_byte and avoid redundant
807 character to byte position calculation ...

829 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
831 * coding.c (Fdefine_coding_system_internal): Use AREF where
832 argument is known to be a vector.
833 * fns.c (Flocale_info): Likewise for ASET.

846 * nsterm.m (NEW_STYLE_FS): Remove.
847 (ns_last_use_native_fullscreen): New variable.
848 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
849 (x_set_window_size): Do not take title bar and tool bar into account
850 if isFullscreen returns YES.
851 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
852 (check_native_fs): New function.
853 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
854 (ns_term_init): Remove NEW_STYLE_FS.

856 and tool bar if isFullscreen returns NO.
857 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
858 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
860 (window:willUseFullScreenPresentationOptions:): New method.
861 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
862 Hide toolbar if not enabled (Bug#13444).

865 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
866 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
867 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
868 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
869 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
870 (syms_of_nsterm): Add ns-use-native-fullscreen.
872 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
874 * fileio.c (Qchoose_write_coding_system): Now static.
876 2013-02-04 Eli Zaretskii <eliz@gnu.org>
878 * xdisp.c (window_buffer_changed): region_showing can be negative,
879 which still means region is being displayed.
880 (redisplay_internal): Resurrect code that forced redisplay of the
881 whole window when showing region and the mark has changed.
882 Record the new mark position to allow redisplay optimizations.
883 (display_line): If it->region_beg_charpos is non-zero, set the
884 window's region_showing member to -1. (Bug#13623) (Bug#13626)
886 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
887 not bitfield of 1 bit.
889 2013-02-03 Daniel Colascione <dancol@dancol.org>
891 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
892 daemon mode works on cygw32 when Emacs is installed and not just
895 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
897 Avoid file time stamp bug on MS-Windows (Bug#13149).
898 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
899 as FAT32 doesn't update time stamps when truncating them.
900 Also, check that a file time stamp is not a multiple of 100 ns;
901 this should catch all instances of the problem on MS-Windows,
902 as its native file system resolution is 100 ns or worse, and
903 checking for a non-multiple of 100 ns should impose only a small
904 overhead on systems with ns resolution.
906 2013-02-02 Eli Zaretskii <eliz@gnu.org>
908 Avoid encoding file names on MS-Windows when they need to be run
909 through dostounix_filename.
910 * w32.c (normalize_filename): Accept an additional argument
911 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
912 downcase it even if w32-downcase-file-names is non-nil.
913 (dostounix_filename): Accept an additional argument MULTIBYTE and
914 pass it to normalize_filename.
915 (emacs_root_dir): Adjust.
917 * msdos.h (dostounix_filename): Adjust prototype.
919 * w32.h (dostounix_filename): Adjust prototype.
921 * msdos.c (dostounix_filename): Accept an additional argument and
923 (init_environment): Adjust callers of dostounix_filename.
925 * fileio.c (Ffile_name_directory, file_name_as_directory)
926 (directory_file_name, Fexpand_file_name)
927 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
929 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
931 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
932 variables, as egetenv is case-insensitive for DOS_NT.
934 * dired.c (file_name_completion): Don't call Fdirectory_file_name
935 with an encoded file name.
937 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
938 Adjust calls to dostounix_filename.
940 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
942 * unexw32.c (unexec): Adjust call to dostounix_filename.
944 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
946 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
949 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
952 * callproc.c (Fcall_process): Make sure program name in PATH and
953 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
954 is passed to exec/spawnve, which fails unless the file-name
957 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
958 even if w32-quote-process-args is nil.

962 Fix timestamp bug when write-region appends nothing (Bug#13149).
963 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
964 the file's time stamp doesn't change if Emacs happens to write nothing
965 to the file, and on a buggy file system this could cause Emacs to
966 incorrectly infer that the file system doesn't have the bug.
967 Avoid this problem by inhibiting the inference in this case.
969 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
971 * window.h (struct window): Convert base_line_number, base_line_pos
972 and column_number_displayed members from Lisp_Object to ptrdiff_t.
973 Convert region_showing member from Lisp_Object to bitfield.
974 Remove sequence_number member. Adjust comments.
975 * window.c (sequence_number): Remove.
976 (make_window): Initialize column_number_displayed.
977 * print.c (print_object): Follow the printed representation of
978 frames and print window pointer to distinguish between windows.
979 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
980 * xdisp.c (wset_base_line_number, wset_base_line_pos)
981 (wset_column_number_displayed, wset_region_showing): Remove.
982 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
983 (try_scrolling, try_cursor_movement, redisplay_window)
984 (try_window_reusing_current_matrix, try_window_id, display_line)
985 (display_mode_lines, decode_mode_spec): Adjust users.
986 * .gdbinit (pwinx): Do not print sequence_number.
988 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
990 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
991 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
992 * dired.c: Include <fcntl.h>.
993 (open_directory): New function, which uses open and fdopendir
994 rather than opendir. DOS_NT platforms still use opendir, though.
995 (directory_files_internal, file_name_completion): Use it.
996 (file_attributes): New function, with most of the old Ffile_attributes.
997 (directory_files_internal, Ffile_attributes): Use it.
998 (file_attributes, file_name_completion_stat): First arg is now fd,
999 not dir name. All uses changed. Use fstatat rather than lstat +
1001 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1002 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1003 (emacs_readlinkat): New function, with much of the old
1004 Ffile_symlink_p, but with an fd argument for speed.
1005 It uses readlinkat rather than careadlinkatcwd, so that it
1006 need not assume the working directory.
1007 (Ffile_symlink_p): Use it.
1008 * filelock.c (current_lock_owner): Use emacs_readlinkat
1009 rather than emacs_readlink.
1010 * lisp.h (emacs_readlinkat): New decl.
1011 (READLINK_BUFSIZE, emacs_readlink): Remove.
1012 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1013 (emacs_norealloc_allocator, emacs_readlink): Remove.
1014 This stuff is moved to fileio.c.
1015 * w32.c (fstatat, readlinkat): New functions.
1016 (careadlinkat): Don't check that fd == AT_FDCWD.
1017 (careadlinkatcwd): Remove; no longer needed.
1019 2013-01-31 Glenn Morris <rgm@gnu.org>

1022 (Fwrite_region): Update for new choose_write_coding_system args.
1023 Move the last piece of choose_write_coding_system here. (Bug#13522)
1024 (syms_of_fileio): Add choose-write-coding-system.
1026 2013-01-30 Eli Zaretskii <eliz@gnu.org>
1028 * w32.c (sys_open): Zero out the flags for the new file descriptor.
1029 (sys_close): Zero out the flags for the file descriptor before
1030 closing it. (Bug#13546)
1032 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1033 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1034 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1037 * w32.c (w32_get_long_filename, init_environment, readlink):
1038 Support file names encoded in DBCS codepages.
1039 (readlink): Use the current file-name-coding-system, not the ANSI
1040 codepage, to decode and handle targets of symlinks.
1042 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1044 * w32.c (opendir): Now accepts a 'const char *'.
1046 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
1048 Remove obsolete redisplay code. See the discussion at
1049 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
1050 * dispnew.c (preemption_period, preemption_next_check): Remove.
1051 (Vredisplay_preemption_period): Likewise.
1052 (update_frame, update_single_window, update_window, update_frame_1):
1053 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
1054 used, following the 2012-06-22 change.
1056 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1058 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1060 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
1062 * font.c (num_fonts): Remove the leftover from old
1063 debugging code. Adjust comment style here and there.
1064 * insdel.c (insert_1): Remove.
1065 * lisp.h (insert_1): Remove prototype.
1066 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
1068 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1070 * w32.c (max_filename_mbslen): New function.
1071 (normalize_filename, readdir): Use it to detect locales where ANSI
1072 encoding of file names uses a double-byte character set (DBCS).
1073 If a DBCS encoding is used, advance by characters using
1074 CharNextExA, instead of incrementing a 'char *' pointer.
1075 Use _mbslwr instead of _strlwr. (Bug#13515)
1077 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1078 request of memory reservation to 1.7GB. (Bug#13065)
1080 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
1082 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
1083 at check_extra_latin label. (Bug#13505)
1085 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1087 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
1088 Avoid redundant calls to strlen.
1090 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1092 Drop async_visible and async_iconified fields of struct frame.
1093 This is possible because async input is gone; for details, see
1094 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1095 * frame.h (struct frame): Remove async_visible and async_iconified
1096 members, convert garbaged to unsigned bitfield. Adjust comments.
1097 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
1098 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
1099 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
1100 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
1101 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
1103 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
1104 properly. Likewise for obscured.
1106 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
1109 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
1111 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1113 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
1114 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1116 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1118 * xdisp.c (message2, message2_nolog): Remove functions.
1119 (message3, message3_nolog): Extract nbytes and multibyteness directly
1120 from the string. Change all callers.
1121 (message3_nolog): Don't set message_enable_multibyte since set_message
1122 will reset it anyway.
1123 (message1, message1_nolog): Use message3.
1124 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1125 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1126 (set_message): Drop all but the second arg, which has to be a string.
1127 (set_message_1): Simplify now that we know that a1 is NULL and the
1128 second arg is a string.
1129 * frame.h (struct frame): Remove `message_buf' field.
1130 Use glyphs_initialized_p instead.
1131 (FRAME_MESSAGE_BUF): Remove macro.
1132 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
1133 * lisp.h (message2, message2_nolog): Remove declarations.
1134 (message3, message3_nolog): Update declarations.
1135 * keyboard.c (read_char_minibuf_menu_text)
1136 (read_char_minibuf_menu_width): Remove vars.
1137 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
1138 to correctly handle multibyte strings.
1139 * frame.c (delete_frame): Don't free message_buf any more.
1140 * editfns.c (message_text, message_length): Remove vars.
1141 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1142 * fileio.c (auto_save_error): Use message3 instead of message2.
1143 * dispnew.c (adjust_frame_message_buffer): Remove function.
1145 2013-01-23 Eli Zaretskii <eliz@gnu.org>
1147 * w32term.c (w32fullscreen_hook): Account correctly for the screen
1148 real estate used for the tool bar and the menu bar.
1150 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
1152 * insdel.c (prepare_to_modify_buffer): Force redisplay if
1153 hidden buffer is prepared to modification (Bug#13164).
1155 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1157 * window.h (struct window): Change window_end_valid member from
1158 Lisp_Object to a bitfield. Adjust comments.
1159 (wset_window_end_valid): Remove.
1160 * window.c (adjust_window_count): Clear window_end_valid.
1161 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
1162 (Fwindow_line_height, set_window_buffer, Frecenter)
1163 (Fsplit_window_internal, Fdelete_other_windows_internal)
1164 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
1165 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
1166 * xdisp.c (check_window_end, reconsider_clip_changes)
1167 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1168 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1169 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1171 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1173 * xdisp.c (mark_window_display_accurate): Simplify the loop
1174 assuming that the only one of vchild, hchild or buffer window
1175 slots is non-nil. Call mark_window_display_accurate_1 for
1176 the leaf windows only.
1177 (mark_window_display_accurate_1): Always assume leaf window.
1180 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1182 * emacs.c (Qkill_emacs_hook): Now static.
1184 * fileio.c (Finsert_file_contents): Simplify.
1185 Remove unnecessary assignments and tests.
1187 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1189 * w32.c (acl_set_file): Don't test for errors unless
1190 set_file_security returns FALSE. Avoids spurious errors when
1193 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1195 * fileio.c (Finsert_file_contents): Revert code introduced at
1196 2013-01-18 in favor of the simpler and generally better fix.
1197 Save stack space by removing 'buffer' and reusing 'read_buf'
1200 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1202 * lisp.h (eabs): Define unconditionally (Bug#13419).
1203 The old "#if !defined (eabs)" was an unnecessary revenant of back
1204 when this macro was called "abs". Document 'eabs' better.
1206 2013-01-19 Glenn Morris <rgm@gnu.org>
1208 * fns.c (Frandom): Doc fix.
1210 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1212 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1213 segfault when there are lots of overlays.
1215 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1216 when there are lots of overlays.
1217 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1218 for the details and a way to reproduce.
1220 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1222 * fileio.c: Use O_APPEND to append.
1223 This corresponds better to the natural interpretation of "append",
1224 and avoids the need to open the output file twice, or to invoke
1225 lseek when APPEND is neither nil nor a number.
1226 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1227 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1228 file possibly twice, and lseeking to its end; this avoids the
1229 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1230 at the same time: the combination is never needed and apparently
1231 it doesn't work with DOS_NT.
1233 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1234 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1236 Allow floating-point file offsets.
1237 Problem reported by Vitalie Spinu in
1238 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1239 * fileio.c (emacs_lseek): Remove.
1240 (file_offset): New function.
1241 (Finsert_file_contents, Fwrite_region): Use it.
1243 2013-01-19 Chong Yidong <cyd@gnu.org>
1245 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1246 aborting on Fsignal (Bug#13289).
1248 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1250 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1251 set_file_security as failure due to insufficient privileges.
1252 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1253 (fstat): Return owner and group like 'stat' and 'lstat' do.
1255 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1257 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1258 The bug was observed on Ubuntu operating inside a virtual machine,
1259 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1260 The workaround introduces a race condition on non-buggy hosts,
1261 but it's an unlikely race and anyway there's a nearly identical
1262 nearby race that can't be fixed.
1263 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1265 (Fwrite_region): Test for file system time stamp bug.
1266 (init_fileio): New function.
1267 * lisp.h (init_fileio): Declare it.
1268 * emacs.c (main): Call it.
1270 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1271 and make it more consistent with other stat-failure diagnostics.
1273 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
1275 Fix crash when inserting data from non-regular files.
1276 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
1277 for the error description produced by valgrind.
1278 * fileio.c (read_non_regular): Rename to read_contents.
1279 Free Lisp_Save_Value object used to pass parameters.
1280 (read_non_regular_quit): Rename to read_contents_quit.
1281 (Finsert_file_contents): Redesign internal file reading loop to adjust
1282 gap and end positions after each read and so help make_gap to work
1283 properly. Do not signal an I/O error too early and so do not leave
1284 not yet decoded characters in a buffer, which was the reason of
1285 redisplay crash. Use list2 to build return value. Adjust comments.
1287 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1289 Close a race when statting and reading files (Bug#13149).
1290 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1291 This avoids a race if the file is renamed between stat and open.
1292 This race is not the problem originally noted in Bug#13149;
1293 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
1295 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

1300 (make_save_pointer): New prototype.
1301 (SAFE_NALLOCA): Fix indentation. Use make_save_pointer.
1302 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
1303 * alloc.c (format_save_value): Rename to make_save_value.
1304 (make_save_pointer): New function.
1305 (record_xmalloc): Use make_save_pointer.
1306 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
1307 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
1308 Change users of make_save_value to make_save_pointer.
1309 Likewise for format_save_value and make_save_value.
1311 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
1313 * buffer.h (NARROWED, BUF_NARROWED): Drop unused macros.
1314 (DECODE_POSITION, BUFFER_CHECK_INDIRECTION): Fix indentation.
1315 * buffer.c (toplevel, syms_of_buffer): Drop old commented-out
1318 2013-01-15 Paul Eggert <eggert@cs.ucla.edu>
1320 * alloc.c (free_save_value): Now static.
1322 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1324 * keymap.c (map_keymap_internal): Use format_save_value.
1325 (map_keymap_char_table_item): Adjust accordingly.
1326 * fileio.c (non_regular_fd, non_regular_inserted)
1327 (non_regular_nbytes): Remove.
1328 (Finsert_file_contents): Convert trytry to ptrdiff_t.
1329 Use format_save_value to pass parameters to read_non_regular.
1330 (read_non_regular): Use XSAVE_ macros to extract parameters.
1332 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
1334 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
1336 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1338 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
1339 extraction from any Lisp_Save_Value slot. Add type checking.
1340 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
1341 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
1342 * xselect.c: All users changed.
1344 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1346 Some convenient bits to deal with Lisp_Save_Values.

1354 * editfns.c (save_excursion_save): Use format_save_value.
1355 (save_excursion_restore): Use XSAVE_OBJECT.
1357 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
1359 Avoid needless casts with XSAVE_POINTER.
1360 * alloc.c (mark_object) [GC_MARK_STACK]:
1361 * dired.c (directory_files_internal_unwind):
1362 * fileio.c (do_auto_save_unwind):
1363 * gtkutil.c (pop_down_dialog):
1364 * keymap.c (map_keymap_char_table_item):
1365 * lread.c (load_unwind):
1366 * nsmenu.m (pop_down_menu):
1367 * print.c (print_object) [GC_MARK_STACK]:
1368 * xfns.c (clean_up_file_dialog):
1369 * xmenu.c (cleanup_widget_value_tree):
1370 Omit casts between XSAVE_POINTER and a pointer type.
1372 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
1374 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
1375 * eval.c (eval_sub): Protect `form' from being GCed before its
1376 car and cdr becomes protected with the backtrace entry.
1378 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
1380 Make Lisp_Save_Value more versatile storage for up to four objects.
1381 * lisp.h (toplevel): Enumeration to describe types of saved objects.
1382 (struct Lisp_Save_Value): New layout. Adjust comments.
1383 (XSAVE_POINTER): New macro.
1384 (XSAVE_INTEGER): Likewise.
1385 (allocate_misc): Add prototype.
1386 (free_misc): Likewise.
1387 * alloc.c (allocate_misc): Now global.
1388 (free_misc): Likewise. Adjust comment.
1389 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
1390 (free_save_value): Likewise.
1391 (mark_object): Likewise.
1392 * editfns.c (save_excursion_save): Pack everything within
1393 Lisp_Save_Value and so avoid xmalloc.
1394 (save_excursion_restore): Adjust to match new layout. Use free_misc
1395 because we do not allocate extra memory any more. Add eassert.
1396 * print.c (print_object): New code to print Lisp_Save_Value. Do not
1397 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

1411 Fix SIGDANGER handlers, for AIX (Bug#13408).
1412 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:

1437 (nsfont_list_family): Add block/unblock_input calls.
1438 (nsfont_open): Move block_input earlier. Add unblock_input before early
1440 (nsfont_draw): Add block/unblock_input calls.

1465 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
1467 Avoid unnecessary byte position calculation for the gap movement.
1468 Since all users of move_gap do CHAR_TO_BYTE for other purposes

1479 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
1481 * term.c (init_tty): Use them instead of rolling our own code.
1482 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
1483 switches from 'signal' to 'pthread_sigmask', which is safer in
1484 multithreaded applications.
1485 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
1486 which has already arranged for that.
1487 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
1488 This is the main part of the bug fix.

1500 predicate, which is how it's really used now. Adjust comment.
1501 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
1502 * buffer.c (buffer_slot_type_mismatch): Remove.
1503 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
1504 predicate. Adjust comment.

1508 right-fringe-width, scroll-bar-width and buffer-display-count.
1509 Use Qstringp for default-directory, buffer-file-name,
1510 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1511 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
1513 * data.c (store_symval_forwarding): Adjust to call the predicate.
1515 2013-01-09 Juanma Barranquero <lekktu@gmail.com>

1529 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
1530 (make_gap_1): New function to adjust the gap of any buffer.
1531 * coding.c (coding_alloc_by_making_gap): Use it.
1532 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
1533 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.

1556 trailing dash is properly added.
1558 2013-01-05 Eli Zaretskii <eliz@gnu.org>
1560 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
1561 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
1562 digits for buffer positions, before misalignment starts.
1563 Display "0" for integer "object" field.
1564 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
1565 Display the newline glyph more unambiguously.
1567 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1569 * nsterm.m (ns_draw_underwave):
1570 * w32term.c (w32_draw_underwave):
1571 * xterm.c (x_draw_underwave): Make underwave look more triangular
1572 and also degrade gracefully for small fonts. (Bug#13000)
1574 * nsterm.m (ns_draw_text_decoration):
1575 * w32term.c (x_draw_glyph_string):
1576 * xterm.c (x_draw_glyph_string): Don't use previous underline
1577 thickness and position if previous underline type is underwave.
1579 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
1581 * fileio.c (Ffile_acl): Undocument return format.
1583 2013-01-02 Glenn Morris <rgm@gnu.org>
1585 * keymap.c (Fkey_description): Doc fix. (Bug#13323)

1595 * lread.c (read_list):
1596 * minibuf.c (Ftry_completion):
1597 * term.c (tty_ins_del_lines):
1598 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
1599 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
1601 2012-12-31 Eli Zaretskii <eliz@gnu.org>
1603 * w32.c (unsetenv): Set up the string passed to _putenv
1605 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
1606 for the bug this caused.
1608 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
1610 * coding.c (Qmac): Now static.
1612 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
1614 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
1615 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

1619 (update_frame_tool_bar): Check toolbar_is_packed for packing.
1620 Show all on TOOLBAR_TOP_WIDGET.
1621 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
1622 by TOOLBAR_TOP_WIDGET.
1623 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
1624 Check toolbar_is_packed.
1625 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on

1627 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
1629 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1630 (xg_update_menubar): Update title only if
1631 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1632 (xg_update_submenu): Skip tearoff only if
1633 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1634 (xg_initialize): Initialize xg_detached_menus only if
1635 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1637 * xterm.h (struct x_output): Surround handlebox_widget with
1638 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
1639 toolbar_in_hbox is bool.
1641 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
1643 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
1644 (LIBS_GNUSTEP): Define.
1645 (LIBES): Add $(LIBS_GNUSTEP).

1648 2012-12-30 Eli Zaretskii <eliz@gnu.org>
1650 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
1651 continuation glyph on a TTY with an indication of an empty line.
1654 2012-12-29 Eli Zaretskii <eliz@gnu.org>
1656 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
1657 file's SELinux context or ACLs successfully set, nil otherwise.
1659 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.

1662 SetEvent and WaitForSingleObject.
1664 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1666 Port EXTERNALLY_VISIBLE to Clang 3.2.
1667 * conf_post.h (__has_attribute): New macro.
1668 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1670 2012-12-27 Glenn Morris <rgm@gnu.org>
1672 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1673 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1675 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1677 * fileio.c (file_name_as_directory, directory_file_name):
1678 Accept an additional argument MULTIBYTE to indicate whether the input C
1679 came from a multibyte or a unibyte Lisp string; all callers
1680 adjusted. Don't assume the input string is always multibyte.
1682 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1683 don't ENCODE_FILE them, and return a unibyte string if the input
1685 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1686 don't assume the input strings will always be multibyte. If the
1687 input strings are multibyte, decode strings obtained from C
1690 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1692 * lisp.h (toplevel): Add two notices to the comment about
1693 defining a new Lisp data type.

1697 * alloc.c (valid_lisp_object_p): Adjust comment.
1699 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1701 * keyboard.c (record_asynch_buffer_change): Initialize an event
1702 only if it's really needed.
1703 * frame.h (enum output_method): Remove output_mac member since
1704 it's a leftover from the deleted code.
1705 * frame.c (Fframep): Adjust user here ...
1706 * terminal.c (Fterminal_live_p): ... and here.
1707 * coding.c (Qmac): Now here because it's only used to denote
1708 end-of-line encoding type.
1709 (syms_of_coding): DEFSYM it.
1710 * frame.h (Qmac): Remove duplicated declaration.
1712 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1714 * window.c (select_window_1): Now static, since it's used only here.
1716 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1718 * window.c (window_body_cols): Subtract display margins from the
1719 window body width on TTYs as well. See
1720 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1721 for the original report.
1723 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1725 * xdisp.c (redisplay_window): Remove inner local variable
1726 because the outer shadowed one has the same meaning.
1727 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1729 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1730 (xg_create_tool_bar): Adjust users.
1732 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1734 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1735 * buffer.c (Fget_buffer_create): Use it to set compact field of
1736 struct buffer_text to avoid accessing an uninitialized value
1737 when compact_buffer is called for the first time.
1738 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1739 (Fset_buffer_modified_p): Use buffer_window_count to check
1740 whether the buffer is displayed in some window.
1741 * xdisp.c (message_dolog): Likewise.
1743 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1745 * w32.c (acl_set_file): If setting the file security descriptor
1746 fails, and the new DACL is identical to the existing one, silently
1747 return success. This fixes problems for users backing up their
1748 own files without having the necessary privileges for setting
1749 security descriptors.
1751 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1753 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1754 after WaitForSingleObject returns normally. This expedites reader
1755 thread shutdown when delete_child triggers it.
1756 (reap_subprocess): More accurate commentary for why we call
1757 delete_child only when cp->fd is negative.
1759 * w32.c (sys_close): Do not call delete_child on a subprocess
1760 whose handle is not yet closed. Instead, set its file descriptor
1761 to a negative value, so that reap_subprocess will call
1762 delete_child on that subprocess when its SIGCHLD arrives.
1763 This avoids closing handles used for communications between sys_select
1764 and reader_thread, which doesn't give sys_select a chance to
1765 notice that the process exited and invoke the SIGCHLD handler for
1768 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1770 * nsfns.m (Fns_do_applescript): Run event loop until script has

1779 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1781 * w32term.c (w32fullscreen_hook): New function.
1782 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1784 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1786 * fileio.c (Finsert_file_contents): Doc fix.
1788 * w32proc.c (new_child, delete_child, find_child_pid): For a
1789 subprocess, consider its slot being in use as long as its process
1790 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1791 slot when a new process is started immediately after killing
1792 another one, without waiting enough time for the first process to
1793 be reaped and resources allocated for it be orderly freed.
1795 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1797 2012-12-21 Chong Yidong <cyd@gnu.org>
1799 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1801 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1803 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1805 * w32.c (get_name_and_id): Always pass NULL as the first argument
1806 of lookup_account_sid. Avoids crashes with UNC file names that
1807 refer to DFS domains, not to specific machine names. (Bug#12621)
1808 Remove now unused argument FNAME; all callers changed.
1809 (get_file_owner_and_group): Remove now unused argument FNAME; all
1812 2012-12-21 Chong Yidong <cyd@gnu.org>
1814 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1815 error for invalid chars, don't check for a nil return value.
1817 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1819 Avoid calls to CHAR_TO_BYTE if byte position is known.
1820 * editfns.c (make_buffer_string_both): Use move_gap_both.
1821 (Fbuffer_string): Use make_buffer_string_both.
1822 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
1824 (buf_bytepos_to_charpos): Likewise.
1825 (charpos_to_bytepos): Remove.
1826 * fileio.c (Finsert_file_contents): Use move_gap_both.
1827 * search.c (Freplace_match): Likewise.
1828 * process.c (process_send_region): Likewise. Use convenient
1829 names for byte positions.
1830 * lisp.h (charpos_to_bytepos): Remove prototype.
1831 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1832 * insdel.c (move_gap): Likewise.

1840 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1841 (redisplay_internal): Don't bother selecting the frame to get the
1842 proper value of frame-local variables (bug#13225).
1844 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1846 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1847 Rename 4th argument since it may be buffer or string. Adjust comment.
1848 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1850 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1852 * coding.c (Fdetect_coding_region): Do not check start and end with
1853 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1854 (code_convert_region): Likewise.
1856 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1858 * w32.c (acl_get_file, acl_set_file): Run the file name through
1859 map_w32_filename, and resolve any symlinks in the file name, like
1861 (acl_set_file): Call revert_to_self, if any privileges were
1864 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
1866 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
1867 ($(BLD)/w32.$(O)): Update dependencies.
1869 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1871 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to

1903 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1905 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1906 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1907 for some of that bug's symptoms can now cause Emacs to abort.
1908 Remove the workaround.
1909 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1910 The bug that caused SIGCHLD to get lost has been fixed, and the
1911 workaround for it can now cause Emacs to abort.
1913 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1915 * sysdep.c (emacs_abort): Bump backtrace size to 40.

1961 delete the file, record it as pending deletion when the subprocess
1964 2012-12-14 Eli Zaretskii <eliz@gnu.org>

1986 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1987 try to get accurate owner and group information from NT file

1989 'lstat', which don't need that information, much faster.
1991 * dired.c (Ffile_attributes) [WINDOWSNT]:
1992 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1993 owner and group information from 'lstat'.

1997 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1998 as that confuses set-auto-coding, so insist on the head-read

2027 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2029 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.

2031 Remove unnecessary S_ISLNK test, as (contra the comments) this
2032 function can't copy symlinks. Improve quality of error message
2033 when attempting to copy files that are neither regular files nor

2345 Convenient macro to check whether the buffer is hidden.
2346 * buffer.h (BUFFER_HIDDEN_P): New macro.
2347 * frame.c (make_frame): Use it. Adjust comment.
2348 * buffer.c (candidate_buffer): New function.
2349 (Fother_buffer, other_buffer_safely): Use it.
2351 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2353 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
2354 if the child process is still running. Instead, exit the wait
2355 loop and return zero. (Bug#13086)
2357 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2359 * frame.h (x_char_width, x_char_height): Remove prototypes.

2370 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
2372 Fix a recently-introduced delete-process race condition.
2373 * callproc.c, process.h (record_kill_process):
2374 New function, containing part of the old call_process_kill.
2375 (call_process_kill): Use it.
2376 This does not change call_process_kill's behavior.
2377 * process.c (Fdelete_process): Use record_kill_process to fix a
2378 race condition that could cause Emacs to lose track of a child.
2380 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2382 Avoid code duplication between prev_frame and next_frame.
2383 * frame.c (candidate_frame): New function. Add comment.
2384 (prev_frame, next_frame): Use it. Adjust comment.
2386 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2388 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2389 fails, signal an error instead of continuing with an empty
2391 Encode expanded temp file pattern before passing it to mkstemp or
2394 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2395 Encode the file name before passing it to dostounix_filename, in
2396 case it will downcase it (under w32-downcase-file-names).
2399 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2401 Minor call-process cleanups.
2402 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2403 at the same time as other platforms, to simplify analysis.
2404 No need for fd0_volatile since we have synch_process_fd.
2405 Avoid needless emacs_close; arg is always negative.
2407 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2409 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2412 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2414 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2415 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2416 and mouse_face_hidden members to a bitfields.
2417 * frame.h (struct frame): Remove set-but-not-used space_width member.
2418 (FRAME_SPACE_WIDTH): Remove.
2419 * nsterm.m, w32term.c, xterm.c: Adjust users.
2420 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2421 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2422 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2423 members to a bitfields.
2425 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2427 Don't let call-process be a zombie factory (Bug#12980).
2428 Fixing this bug required some cleanup of the signal-handling code.
2429 As a side effect, this change also fixes a longstanding rare race
2430 condition whereby Emacs could mistakenly kill unrelated processes,
2431 and it fixes a bug where a second C-g does not kill a recalcitrant
2432 synchronous process in GNU/Linux and similar platforms.
2433 The patch should also fix the last vestiges of Bug#9488,
2434 a bug which has mostly been fixed on the trunk by other changes.
2435 * callproc.c, process.h (synch_process_alive, synch_process_death)
2436 (synch_process_termsig, sync_process_retcode):
2437 Remove. All uses removed, to simplify analysis and so that
2438 less consing is done inside critical sections.
2439 * callproc.c (call_process_exited): Remove. All uses replaced
2440 with !synch_process_pid.
2441 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2442 These take the role of what used to be in unwind-protect arg.
2444 (block_child_signal, unblock_child_signal):
2445 New functions, to avoid races that could kill innocent-victim processes.
2446 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2447 (call_process_kill): Record killed processes as deleted, so that
2448 zombies do not clutter up the system. Do this inside a critical
2449 section, to avoid a race that would allow the clutter.
2450 (call_process_cleanup): Fix code so that the second C-g works again
2451 on common platforms such as GNU/Linux.
2452 (Fcall_process): Create the child process in a critical section,
2453 to fix a race condition. If creating an asynchronous process,
2454 record it as deleted so that zombies do not clutter up the system.
2455 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2456 light of these changes. Omit unnecessary call to emacs_close
2457 before failure, as the unwind-protect code does that.
2458 * callproc.c (call_process_cleanup):
2459 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2460 * process.c (record_deleted_pid): New function, containing
2461 code refactored out of Fdelete_process.
2462 (Fdelete_process): Use it.
2463 (process_status_retrieved): Remove. All callers changed to use
2464 child_status_change.
2465 (record_child_status_change): Remove, folding its contents into ...
2466 (handle_child_signal): ... this signal handler. Now, this
2467 function is purely a handler for SIGCHLD, and is not called after
2468 a synchronous waitpid returns; the synchronous code is moved to
2469 wait_for_termination. There is no need to worry about reaping
2470 more than one child now.
2471 * sysdep.c (get_child_status, child_status_changed): New functions.
2472 (wait_for_termination): Now takes int * status and bool
2473 interruptible arguments, too. Do not record child status change;
2474 that's now the caller's responsibility. All callers changed.
2475 Reimplement in terms of get_child_status.
2476 (wait_for_termination_1, interruptible_wait_for_termination):
2477 Remove. All callers changed to use wait_for_termination.
2478 * syswait.h: Include <stdbool.h>, for bool.
2479 (record_child_status_change, interruptible_wait_for_termination):
2481 (record_deleted_pid, child_status_changed): New decls.
2482 (wait_for_termination): Adjust to API changes noted above.
2484 * bytecode.c, lisp.h (Qbytecode): Remove.
2485 No longer needed after 2012-11-20 interactive-p changes.
2487 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2489 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2490 the scroll margin, move point outside the margin. (Bug#13055)
2492 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2494 * gtkutil.c (my_log_handler): New function.
2495 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2497 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2499 * lisp.h (modify_region): Rename to...
2500 (modify_region_1): ...new prototype.
2501 * textprop.c (modify_region): Now static. Adjust users.
2502 * insdel.c (modify_region): Rename to...
2503 (modify_region_1): ...new function to work with current buffer.
2504 Adjust comment and users. Use true and false for booleans.
2506 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2508 * alloc.c (free_save_value): New function.
2509 (safe_alloca_unwind): Use it.
2510 * lisp.h (free_save_value): New prototype.
2511 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2513 (save_excursion_restore): Adjust to match saved data structure.
2514 Use free_save_value to offload some work from GC. Drop obsolete
2517 2012-12-03 Chong Yidong <cyd@gnu.org>
2519 * fileio.c (Vauto_save_list_file_name): Doc fix.
2521 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2523 * w32fns.c: Remove prototype of atof.
2524 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2526 (file_dialog_callback): Make it UINT_PTR.
2528 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2531 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2532 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2535 2012-12-03 Glenn Morris <rgm@gnu.org>
2537 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2539 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2541 Fix xpalloc confusion after memory is exhausted.
2542 * alloc.c (xpalloc): Comment fix.
2543 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2544 and signals an error, do not clear charset_table_size, as
2545 charset_table is still valid.
2546 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2548 Use execve to avoid need to munge environ (Bug#13054).
2549 * callproc.c (Fcall_process):
2550 * process.c (create_process):
2551 Don't save and restore environ; no longer needed.
2552 * callproc.c (child_setup):
2553 Use execve, not execvp, to preserve environ.
2555 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2557 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2559 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2561 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2562 display for sliced images (Bug#10500).
2564 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2566 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2568 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2569 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2571 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2573 * xdisp.c (window_outdated): Remove eassert since it hits
2574 some suspicious corner cases (see Bug#13007 and Bug#13012).
2575 (mode_line_update_needed): New function.
2576 (redisplay_internal, redisplay_window): Use it.
2577 (ensure_selected_frame): New function.
2578 (redisplay_internal, unwind_redisplay): Use it.
2579 (redisplay_internal): Move comment about buffer_shared...
2580 (buffer_shared_and_changed): ...near to its real use.
2582 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2584 * callproc.c (Fcall_process): Don't misreport vfork failure.
2586 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2588 * callproc.c (Fcall_process): Fix vfork portability problems.
2589 Do not assume that fd[0], count, filefd, and save_environ survive
2590 vfork. Fix bug whereby wrong errno value could be reported for
2591 pipe failure. Some minor cleanups, too, as follows. Move buf and
2592 bufsize to the context where they're needed. Change new_argv to
2593 be of type char **, as this is more convenient and avoids casts.
2594 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2595 Now local constants, not macros.
2597 2012-11-18 Kenichi Handa <handa@gnu.org>
2599 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2600 for the variable "f".
2602 2012-11-13 Kenichi Handa <handa@gnu.org>
2604 * font.c (font_unparse_xlfd): Exclude special characters from the
2605 generating XLFD name.
2607 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

2620 * lread.c (readbyte_from_file): Assume EINTR is defined.
2621 * process.c (wait_reading_process_output, send_process) [subprocesses]:
2622 Assume EIO and EAGAIN are defined.
2623 * unexcoff.c (write_segment): Assume EFAULT is defined.
2625 2012-11-27 Eli Zaretskii <eliz@gnu.org>

2642 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
2643 were always defined.
2645 2012-11-24 Eli Zaretskii <eliz@gnu.org>
2647 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2648 between bpos_covered and bpos_max. This fixes cursor display when
2649 several display strings follow each other.
2651 * .gdbinit (pgx): If the glyph's object is a string, display the
2652 pointer to string data, rather than the value of the string object
2653 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2655 * indent.c (Fvertical_motion): If the starting position is covered
2656 by a display string, return to one position before that, to avoid
2657 overshooting it inside move_it_to. (Bug#12930)
2659 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>

2669 asked_for_visible and menubar_active members.
2670 Drop unused pending_menu_activation member.
2671 * xterm.h (struct x_output): Drop outdated #if 0 code.
2672 Use bitfields for explicit_parent, asked_for_visible,
2673 has_been_visible and net_wm_state_hidden_seen members.

2678 of a literal "/". (Bug#12955)
2679 (gl-stamp): Invoke fc.exe directly, not through cmd.
2681 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
2683 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
2684 * dired.c: Assume HAVE_DIRENT_H.
2685 (NAMLEN): Remove, replacing with ...
2686 (dirent_namelen): New function. All uses changed. Use the GNU macro
2687 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2688 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2689 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2690 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2692 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2693 * ndir.h: Rename to ../nt/inc/dirent.h.
2694 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2695 Do not include <dirent.h>; no longer needed.
2696 * w32.c: Include <dirent.h> rather than "ndir.h".
2698 2012-11-23 Chong Yidong <cyd@gnu.org>
2700 * xftfont.c (xftfont_open): Remove duplicate assignment.
2702 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2704 * alloc.c (Fgarbage_collect): Unblock input after clearing
2705 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2706 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2707 * msdos.c (IT_frame_up_to_date): Use it here...
2708 * w32term.c (w32_frame_up_to_date): ...here...
2709 * xterm.c (XTframe_up_to_date): ...and here...
2710 * nsterm.m (ns_frame_up_to_date): ...but not here.
2711 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2713 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2714 Do not check whether GC is in progress.
2716 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2718 * xdisp.c (window_buffer_changed): New function.
2719 (update_menu_bar, update_tool_bar): Use it to
2720 simplify large 'if' statements.
2721 (redisplay_internal): Generalize commonly used
2722 'tail' and 'frame' local variables.
2724 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2726 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2727 with Windows system header.
2729 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2731 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).

2748 * emacs.c (main): Set the G_SLICE environment variable for all
2749 Cygwin builds, not just GTK builds. See
2750 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2752 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2754 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2755 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2756 Define for the MSVC compiler.
2758 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2760 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2761 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2762 dostounix_filename. Prevents crashes down the road, because
2763 dostounix_filename assumes it gets a unibyte string.
2764 Reported by Michel de Ruiter <michel@sentient.nl>, see

2803 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2804 cygwin_convert_file_name*.
2806 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2807 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2809 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2811 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2813 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2815 * w32select.c: Include w32common.h before w32term.h, so that
2816 windows.h gets included before w32term.h uses some of its
2817 features, see below.
2819 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2821 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
2823 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
2825 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2827 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2828 (ns_select): Return at once if events are held (Bug#12834).
2830 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2832 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2833 Needed following 2012-10-20 change. (Bug#12902)
2835 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2837 * w32proc.c (waitpid): Remove unused label get_result.
2839 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2841 * makefile.w32-in (SYSWAIT_H): New macro.
2842 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2843 ($(BLD)/sysdep.$(O)): Update dependencies.
2845 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2847 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2848 * callproc.c (relocate_fd): Assume F_DUPFD.
2849 * emacs.c, term.c (O_RDWR): Remove.
2850 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2851 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2852 * nsterm.m: Assume <fcntl.h> exists.
2853 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2854 (create_pty, Fmake_network_process, server_accept_connection)
2855 (wait_reading_process_output, init_process_emacs):
2857 (wait_reading_process_output): Put in a special case for WINDOWSNT
2858 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2859 It's not clear this is needed, but it's a more-conservative change.
2860 (create_process): Assume FD_CLOEXEC.
2861 (create_process, create_pty): Assume O_NOCTTY.
2862 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2863 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2864 Omit if not DOS_NT, since F_GETFL is not defined there.
2865 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2866 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2868 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2869 lack it, since gnulib guarantees this.
2870 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2872 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2874 * w32.c (faccessat): Pretend that directories have the execute bit
2875 set. Emacs expects that, e.g., in files.el:cd-absolute.
2877 * w32proc.c (create_child): Don't clip the PID of the child
2878 process to fit into an Emacs integer, as this is no longer a
2880 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2881 reaping only the process specified by PID argument, if that is
2882 positive. Use PID instead of dead_child to know which process to
2883 reap. Wait for the child to die only if WNOHANG is not in
2885 (sys_select): Don't set dead_child.
2887 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2888 as it is no longer needed.
2890 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2892 (record_child_status_change): Remove the setting of
2893 record_at_most_one_child for the !WNOHANG case.
2895 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2897 Fix problems in ns port found by static checking.
2898 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2899 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2900 not to process group.
2901 (ns_select): Use emacs_write, not write, as that's more robust
2902 in the presence of signals.
2903 (fd_handler:): Check for read errors.
2905 2012-11-16 Glenn Morris <rgm@gnu.org>
2907 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2909 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2911 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2913 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2915 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2916 use the same value of thread handle.
2917 (start_timer_thread): If the timer thread exited (due to error),
2918 clean up by closing the two handles it used. Duplicate the caller
2919 thread's handle here, so it gets duplicated only once, when
2920 launching the timer thread. Set priority of the timer thread, not
2922 (getitimer): Don't duplicate the caller thread's handle here.
2925 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2927 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2930 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2932 Remove no-longer-used pty_max_bytes variable.
2933 * process.c (pty_max_bytes): Remove; unused.
2934 (send_process): Do not set it.
2936 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2938 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2939 Update dependencies.
2941 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2943 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2944 This follows up on the 2012-09-29 patch that removed indirection
2945 for the 'function' field. Reported by Sergey Vinokurov in
2946 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2948 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2950 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2951 different name, as the MS runtime does not have such a function,
2952 and probably never will.) All callers changed. Ignore DIRFD
2953 value if PATH is an absolute file name, to match Posix spec
2954 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2957 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2959 * xdisp.c (echo_area_display, redisplay_internal):
2960 Omit redundant check whether frame_garbaged is set.
2962 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2964 Use faccessat, not access, when checking file permissions (Bug#12632).
2965 This fixes a bug that has been present in Emacs since its creation.
2966 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2967 which must set some sort of record. (Torek's bug report was against
2968 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2969 same common flaw.) See Torek's Usenet posting
2970 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2971 Posted: Fri Apr 8 14:18:56 1983.
2972 * Makefile.in (LIB_EACCESS): New macro.
2974 * callproc.c (init_callproc):
2975 * charset.c (init_charset):
2976 * fileio.c (check_existing, check_executable, check_writable)
2978 * lread.c (openp, load_path_check):
2979 * process.c (allocate_pty):
2981 Use effective UID when checking permissions, not real UID.
2982 * callproc.c (init_callproc):
2983 * charset.c (init_charset):
2984 * lread.c (load_path_check, init_lread):
2985 Test whether directories are accessible, not merely whether they exist.
2986 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2987 * fileio.c (check_existing, check_executable, check_writable)
2989 Use symbolic names instead of integers for the flags, as they're
2991 (check_writable): New arg AMODE. All uses changed.
2992 Set errno on failure.
2993 (Ffile_readable_p): Use faccessat, not stat + open + close.
2994 (Ffile_writable_p): No need to call check_existing + check_writable.
2995 Just call check_writable and then look at errno. This saves a syscall.
2996 dir should never be nil; replace an unnecessary runtime check
2997 with an eassert. When checking the parent directory of a nonexistent
2998 file, check that the directory is searchable as well as writable, as
2999 we can't create files in unsearchable directories.
3000 (file_directory_p): New function, which uses 'stat' on most platforms
3001 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3002 (Ffile_directory_p, Fset_file_times): Use it.
3003 (file_accessible_directory_p): New function, which uses a single
3004 syscall for efficiency.
3005 (Ffile_accessible_directory_p): Use it.
3006 * xrdb.c (file_p): Use file_directory_p.
3007 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3008 * lread.c (openp): When opening a file, use fstat rather than
3009 stat, as that avoids a permissions race. When not opening a file,
3010 use file_directory_p rather than stat.
3011 (dir_warning): First arg is now a usage string, not a format.
3012 Use errno. All uses changed.
3013 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3014 that merely introduced a race.
3015 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3016 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3017 and similarly for the other O_* flags.
3018 * w32.c (sys_faccessat): Rename from sys_access and switch to
3019 faccessat's API. All uses changed.
3020 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3021 (magic_db): Rename from magic_file_p.
3022 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3023 char *, so that we don't have to test for file existence
3024 separately from opening the file for reading. This removes a race
3025 fixes a permission-checking problem, and simplifies the code.
3027 (file_p): Remove; no longer needed.
3029 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3031 Omit glyphs initialization at startup.
3032 * dispnew.c (glyphs_initialized_initially_p): Remove.
3033 (adjust_frame_glyphs_initially): Likewise. Adjust users.
3034 (Fredraw_frame): Move actual code from here...
3035 (redraw_frame): ...to here. Add eassert. Adjust comment.
3036 (Fredraw_display): Use redraw_frame.
3037 * xdisp.c (clear_garbaged_frames): Likewise.
3039 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3041 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3042 passed to pint2str and pint2hrstr to be at most the size of the
3043 frame's decode_mode_spec_buffer. This avoids crashes with very
3044 large values of FIELD_WIDTH argument to decode_mode_spec.
3047 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3049 Fix a race with verify-visited-file-modtime (Bug#12863).
3050 Since at least 1991 Emacs has ignored an mtime difference of no
3051 more than one second, but my guess is that this was to work around
3052 file system bugs that were fixed long ago. Since the race is
3053 causing problems now, let's remove that code.
3054 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3055 whose time stamp is off by no more than a second. Insist that the
3056 file time stamps match exactly.
3058 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3060 * frame.h (struct frame): Convert external_tool_bar member to
3061 1-bit unsigned bitfield.
3062 * termhooks.h (struct terminal): Remove mouse_moved member since
3063 all users are long dead. Adjust comment on mouse_position_hook.
3065 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3067 Simplify by using FOR_EACH_FRAME here and there.
3068 * frame.c (next_frame, prev_frame, other_visible_frames)
3069 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
3070 * w32term.c (x_window_to_scroll_bar): Likewise.
3071 * window.c (window_list): Likewise.
3072 * xdisp.c (x_consider_frame_title): Likewise.
3073 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
3074 * xfns.c (x_window_to_frame, x_any_window_to_frame)
3075 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
3076 * xmenu.c (menubar_id_to_frame): Likewise.
3077 * xselect.c (frame_for_x_selection): Likewise.
3078 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3079 (x_window_to_menu_bar): Likewise.
3080 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3082 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3084 * data.c (Qdefalias_fset_function): Now static.
3086 Another tweak to vectorlike_header change.
3087 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3088 Remove, and replace all uses with ...
3089 (next_in_free_list, set_next_in_free_list):
3090 New functions, which respect C's aliasing rules better.
3092 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3094 * window.c (list4i): Rename from 'quad'. All uses changed.
3095 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3097 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3099 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3100 warning about mixing declarations and code in ISO C90.
3102 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3104 * window.c (Fsplit_window_internal): Set combination limit of
3105 new parent window to t iff Vwindow_combination_limit is t;
3106 fixing a regression introduced with the change from 2012-09-22.
3107 (Fset_window_combination_limit): Fix doc-string.
3109 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3111 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3112 amount when the scroll margins are too large. When scrolling
3113 backwards in the buffer, give up if cannot reach point or the
3114 scroll margin within a reasonable number of screen lines.
3115 Fixes point position in window under scroll-up/down-aggressively when
3116 point is positioned many lines beyond the window top/bottom.
3119 * ralloc.c (relinquish): If real_morecore fails to return memory
3120 to the system, don't crash; instead, leave the last heap
3121 unchanged and return. (Bug#12774)
3123 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3125 * lisp.h (AUTOLOADP): New macro.
3126 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
3127 * data.c (Ffset): Remove special ad-advice-info handling.
3128 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
3130 (Finteractive_form): Simplify.
3131 (Fquo): Don't insist on having at least 2 arguments.
3132 (Qdefalias_fset_function): New var.
3134 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3136 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

3140 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
3142 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3144 Fix recently introduced crash on MS-Windows (Bug#12839).
3145 * w32term.h (struct scroll_bar): Use convenient header.
3146 (SCROLL_BAR_VEC_SIZE): Remove.
3147 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3149 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3151 Tweak last vectorlike_header change.
3152 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3153 vectorlike object on the free list. This is introduced to avoid
3154 some (but not all) pointer casting and aliasing problems, see
3155 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3156 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
3158 (xvectype, xvecsize): Use them to examine Lisp_Object values.
3160 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3162 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3163 been removed, so remove them here also.
3165 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3167 * doc.c (Fdocumentation): Handle new property
3168 dynamic-docstring-function to replace the old ad-advice-info.
3170 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
3172 * fns.c (Qeql, hashtest_eq): Now static.
3174 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>

3177 * fns.c (hashfn_eq, hashfn_eql, sxhash):
3178 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
3179 * buffer.c (compare_overlays): Use XLI rather than XHASH.
3181 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
3183 Use same hash function for hashfn_profiler as for hash_string etc.
3184 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
3185 * lisp.h (sxhash_combine): New inline function, with the contents
3186 of the old SXHASH_COMBINE.
3187 * profiler.c (hashfn_profiler): Use it, instead of having a
3188 special hash function containing a comparison that always yields 1.
3190 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3192 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3193 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3194 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3197 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3199 * image.c (xpm_make_color_table_h): Fix compiler error because
3200 make_hash_table changed.
3202 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
3204 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3206 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3208 Use ad-hoc comparison function for the profiler's hash-tables.
3209 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3210 (make_log): Use them.
3211 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3212 call Fequal any more.
3213 (Ffunction_equal): New function.
3214 (cmpfn_profiler, hashfn_profiler): New functions.

3221 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
3222 (hash_lookup, hash_remove_from_table): Move assertion checking of
3223 hashfn result here. Check hash-equality before calling cmpfn.
3224 (Fmake_hash_table): Adjust call to make_hash_table.
3225 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
3226 (syms_of_fns): Initialize them.

3230 * print.c (print_object): Adjust to new hash-table struct.
3231 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
3233 2012-11-08 Eli Zaretskii <eliz@gnu.org>
3235 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
3236 value of w32-scroll-lock-modifier is neither nil nor one of the
3237 known key modifiers. (Bug#12806)
3239 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3241 Shrink struct vectorlike_header to the only size field.
3242 * lisp.h (enum pvec_type): Avoid explicit enum member values.
3244 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
3245 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
3246 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
3247 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
3248 information from the vector header. Adjust comment.

3255 (allocate_pseudovector): Adjust prototype.
3256 * alloc.c (mark_glyph_matrix, mark_face_cache, allocate_string)
3257 (sweep_string, lisp_malloc): Remove useless prototypes.
3258 (enum mem_type): Adjust comment.
3259 (NEXT_IN_FREE_LIST): New macro.
3260 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
3261 (Fmake_bool_vector): Likewise.
3262 (struct large_vector): New type to represent allocation unit for
3263 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3264 (large_vectors): Change type to struct large_vector.
3265 (allocate_vector_from_block): Simplify.
3266 (PSEUDOVECTOR_NBYTES): Replace with...
3267 (vector_nbytes): ...new function. Adjust users.
3268 (sweep_vectors): Adjust processing of large vectors.
3269 (allocate_vectorlike): Likewise.
3270 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
3271 Add easserts. Adjust XSETPVECTYPESIZE usage.
3272 (allocate_buffer): Use BUFFER_PVEC_INIT.
3273 (live_vector_p): Adjust to match large vector.
3274 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
3275 * buffer.h (struct buffer): Add next member.
3276 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
3278 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
3279 * fns.c (internal_equal): Adjust to match enum pvec_type change.
3280 (copy_hash_table): Adjust to match vector header change.

3283 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
3284 (xvecsize): New command.
3286 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3288 * keyboard.c (event_to_kboard): Do not dereference
3289 frame_or_window field of SELECTION_REQUEST_EVENT
3290 and SELECTION_CLEAR_EVENT events (Bug#12814).
3291 * xterm.h (struct selection_input_event): Adjust comment.
3293 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3295 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3296 such as Scroll Lock, if the respective keys are treated as
3297 function keys, not as modifiers. This avoids destroying non-ASCII
3298 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3300 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3302 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3304 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3306 Restore some duplicate definitions (Bug#12814).
3307 This undoes part of the 2012-11-03 changes. Some people build
3308 with plain -g rather than with -g3, and they need the duplicate
3309 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3310 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3311 Define as macros, as well as as enums or as constants.
3313 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
3315 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
3316 to keypad keys (Bug#12816).
3318 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3320 Minor adjustments of recently-changed frame functions.
3321 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3322 known to be a frame (we're in the FRAMEP branch).
3323 * lisp.h (Qframep): Remove decl. frame.h declares this.
3324 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3325 since they're meant for Lisp fixnum values.
3327 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3329 * window.c (Fwindow_combination_limit): Revert to the only
3330 required argument and adjust docstring as suggested in
3331 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3332 by Martin Rudalics <rudalics@gmx.at>.
3334 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3336 Widely used frame validity and checking functions.
3337 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
3338 * frame.c (decode_live_frame, decode_any_frame): New functions.
3339 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
3340 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
3341 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
3342 (Fframe_pointer_visible_p): Use decode_any_frame.
3343 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
3344 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
3345 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
3346 (Fframe_focus): Likewise. Allow zero number of arguments.
3348 (frame_buffer_list, frame_buffer_predicate): Remove.
3349 * lisp.h (frame_buffer_predicate): Remove prototype.
3350 * buffer.c (Fother_buffer): Use decode_any_frame.
3351 * xdisp.c (Ftool_bar_lines_needed): Likewise.
3352 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3353 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3354 (Fclose_font, Ffont_info): Use decode_live_frame.
3355 * fontset.c (check_fontset_name): Likewise.
3356 * terminal.c (Fframe_terminal): Likewise.
3357 * w32fns.c (check_x_frame): Likewise.
3358 * window.c (Fminibuffer_window, Fwindow_at)
3359 (Fcurrent_window_configuration): Likewise.
3360 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
3361 Likewise. Allow zero number of arguments. Adjust docstring.
3362 * dispnew.c (Fredraw_frame): Likewise.
3363 * xfaces.c (frame_or_selected_frame): Remove.
3364 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3365 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3366 (Fframe_face_alist): Use decode_live_frame.
3367 * xfns.c (check_x_frame): Likewise.
3369 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3371 * window.c (quad): New function.
3372 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3373 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3374 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3375 (Fwindow_line_height): Use it.
3376 (Fwindow_fringes): Use list3.
3377 (Fwindow_scroll_bars): Use list4.
3378 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3379 (Fwindow_combination_limit): Allow zero number of arguments.
3381 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3383 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3385 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3386 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3387 file descriptor 2 for standard error. (Bug#12805)
3389 2012-11-05 Chong Yidong <cyd@gnu.org>
3391 * process.c (wait_reading_process_output): Revert previous change.
3393 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3395 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3396 This removes code that has been obsolete since around 1990.
3397 * callproc.c (Fcall_process):
3399 * process.c (create_process):
3400 * term.c (dissociate_if_controlling_tty):
3401 Assume setsid exists.
3402 * callproc.c (child_setup): Assume setpgid exists and behaves as
3403 per POSIX.1-1988 or later.
3404 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3405 * emacs.c (shut_down_emacs):
3406 * sysdep.c (sys_suspend, init_foreground_group):
3407 Assume getpgrp behaves as per POSIX.1-1998 or later.
3408 * msdos.c (setpgrp): Remove.
3409 (tcgetpgrp, setpgid, setsid): New functions.
3410 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3411 * term.c (no_controlling_tty): Remove; unused.
3412 * w32proc.c (setpgrp): Remove.
3413 (setsid, tcgetpgrp): New functions.
3415 Simplify by assuming __fpending.
3416 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3417 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3418 Do not assume that __fpending's result fits in int.
3420 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3422 Remove EMACS_OUTQSIZE+sleep hack.
3423 * dispnew.c (update_frame_1): Remove hack for terminals slower
3424 than 2400 bps, which throttled Emacs by having it sleep.
3425 This code hasn't worked since at least 2007, when the multi-tty stuff
3426 was added, and anyway those old terminals are long dead.
3427 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3428 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3430 Fix data-loss with --version (Bug#9574).
3431 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3432 as we can't assume that emacs_strerror is initialized, and strerror
3433 is good enough here.
3434 (main): Invoke atexit earlier, to catch earlier instances of
3435 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3437 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3439 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3440 (keyDown): Remap keypad keys to X11 virtual key codes.
3442 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3444 Fix data-loss with --batch (Bug#9574).
3445 * emacs.c: Include <close-stream.h>.
3446 (close_output_streams): New function.
3447 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3448 and handles errors appropriately.
3449 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3452 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3453 The symptom is a diagnostic "GLib-WARNING **: In call to
3454 g_spawn_sync(), exit status of a child process was requested but
3455 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3456 waitpid(), so exit status can't be returned." The diagnostic
3457 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3458 The real bug is a race condition between Emacs and glib: Emacs
3459 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3460 so that glib can't find it. Work around the bug by invoking
3461 waitpid only on subprocesses that Emacs itself creates.
3462 * process.c (create_process, record_child_status_change):
3463 Don't use special value -1 in pid field, as the caller now must
3464 know the pid rather than having the callee infer it.
3465 The inference was sometimes incorrect anyway, due to another race.
3466 (create_process): Set new 'alive' member if child is created.
3467 (process_status_retrieved): New function.
3468 (record_child_status_change): Use it.
3469 Accept negative 1st argument, which means to wait for the
3470 processes that Emacs already knows about. Move special-case code
3471 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3472 processes that have already been waited for, by testing and
3473 clearing new 'alive' member.
3474 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3475 now does this internally.
3476 (handle_child_signal): Let record_child_status_change do all
3477 the work, since we do not want to reap all exited child processes,
3478 only the child processes that Emacs itself created.
3479 * process.h (Lisp_Process): New boolean member 'alive'.
3481 Omit duplicate definitions no longer needed with gcc -g3.
3482 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3483 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3484 Define only as macros. There's no longer any need to also define
3485 these symbols as enums or as constants, since we now assume
3486 gcc -g3 when debugging.
3488 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3490 * lisp.mk: Adjust comments to the fact that term/internal is now
3491 loaded from loadup.el.
3493 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3494 (msdos_fatal_signal): New function.
3495 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3498 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3499 for GCC versions before 4.
3500 (emacs_raise): Define to call msdos_fatal_signal.
3502 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3503 iterator when starting in the middle of a display or overlay
3506 2012-11-03 Chong Yidong <cyd@gnu.org>
3508 * process.c (wait_reading_process_output): Clean up the last
3511 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3513 * process.c (wait_reading_process_output): Avoid a race condition
3514 with SIGIO delivery (Bug#11536).
3516 2012-11-03 Chong Yidong <cyd@gnu.org>
3518 * buffer.c (cursor_type): Untabify docstring.
3520 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3522 * frame.h (struct frame): Drop can_have_scroll_bars member
3523 which is meaningless for a long time. Adjust comments.
3524 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3525 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3527 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3529 * window.c (decode_next_window_args): Update window arg after
3530 calling decode_live_window and so fix crash reported at
3531 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3532 by Juanma Barranquero <lekktu@gmail.com>.
3533 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3534 * font.c (Ffont_at): Likewise.
3536 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3538 * widget.c (resize_cb): New function.
3539 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3540 (EmacsFrameResize): Check if all is up to date before changing frame
3543 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3545 Implement backtrace output for fatal errors on MS-Windows.
3546 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3547 (BACKTRACE_LIMIT_MAX): New macro.
3548 (w32_backtrace): New function.
3549 (emacs_abort): Use w32_backtrace when the user chooses not to
3550 attach a debugger. Update the text of the abort dialog.
3552 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3554 Window-related stuff cleanup here and there.
3555 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3556 Use decode_any_window.
3557 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3558 * xdisp.c (Fformat_mode_line): Likewise.
3559 * font.c (Ffont_at): Use decode_live_window.
3560 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3561 * window.c (decode_next_window_args): Likewise.
3562 (decode_any_window): Remove static.
3563 * window.h (decode_any_window): Add prototype.
3564 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3565 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3568 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3570 Remove pad from struct input_event.
3571 * termhooks.h (struct input_event): Remove padding field.
3573 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3574 member is never cons for a long time. Adjust comment.
3575 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3576 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3577 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3578 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3580 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3582 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3584 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3586 Fix crash when using Emacs as commit editor for git (Bug#12697).
3587 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3588 and it is configured in conf_post.h.
3589 (Fcall_process): Don't invoke both setsid and setpgid; the former
3590 is enough, if it exists.
3591 * callproc.c (Fcall_process, child_setup):
3592 * process.c (create_process): Use setpgid.
3593 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3595 * dispnew.c (init_display): Initialize the foreground group
3596 if we are running a tty display.
3597 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3598 * lisp.h (init_foreground_group): New decl.
3599 * sysdep.c (inherited_pgroup): New static var.
3600 (init_foreground_group, tcsetpgrp_without_stopping)
3601 (narrow_foreground_group, widen_foreground_group): New functions.
3602 (init_sys_modes): Narrow foreground group.
3603 (reset_sys_modes): Widen foreground group.
3605 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3607 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3609 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3611 * minibuf.c (read_minibuf): Restore current buffer since
3612 choose_minibuf_frame calling Fset_frame_selected_window may
3613 change it (Bug#12766).
3615 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3617 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3619 2012-10-30 Kenichi Handa <handa@gnu.org>
3621 * font.c (Ffont_at): If WINDOW is specified and it is not
3622 displaying the current buffer, signal an error.
3624 2012-10-29 Daniel Colascione <dancol@dancol.org>
3626 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3627 In preparation for fixing bug#12739, move these functions from
3630 * coding.h, coding.c: ... to here, and compile them only when
3631 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3632 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3634 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3636 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3637 (timer_loop, getitimer, setitimer): Use it instead of
3638 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3640 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3643 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3645 * nsterm.m (NO_APPDEFINED_DATA): New define.
3646 (last_appdefined_event_data): New variable
3647 (last_appdefined_event): Remove.
3648 (ns_select): Initialize t from last_appdefined_event_data instead
3649 of [last_appdefined_event data1].
3650 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3651 remove last_appdefined_event (Bug#12698).
3653 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3655 * frame.c (x_set_font): Catch internal error.
3657 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3659 Avoid overflow in w32 implementation of interval timers.
3660 When possible, for ITIMER_PROF count only times the main thread
3662 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3663 'volatile ULONGLONG' types. All the other data which was
3664 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3665 (GetThreadTimes_Proc): New typedef.
3666 (w32_get_timer_time): New function, returns a suitable time value
3668 (timer_loop): Enter critical section when accessing ULONGLONG
3669 values of the itimer_data struct, as these accesses are no longer
3670 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3671 Remove unused variable.
3672 (init_timers): Initialize s_pfn_Get_Thread_Times.
3673 (start_timer_thread): Don't assign itimer->caller_thread here.
3674 (getitimer): Assign itimer->caller_thread here.
3675 (setitimer): Always call getitimer to get the value of ticks_now.
3676 (sys_spawnve): Avoid compiler warning about format mismatch.
3678 2012-10-26 Eli Zaretskii <eliz@gnu.org>
3680 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3681 mouse movement events if the menu bar is active. This avoids
3682 producing a busy "hour-glass" cursor by Windows if the mouse
3683 pointer is positioned over a tooltip shown for some menu item.
3685 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3687 Don't assume process IDs fit in int.
3688 * emacs.c (shut_down_emacs) [!DOS_NT]:

4169 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4170 (OS_NT, os_subtype, cache_system_info): Move here.
4172 * unexw32.c, unexcw.c: Include w32common.h.
4174 * emacs.c (main): Use (defined (WINDOWSNT) || defined
4175 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
4176 to call syms_of_w32select.
4178 * cygw32.h: Remove obsolete EXFUN declarations.
4180 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
4182 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
4183 of w32inevt.o from SOME_MACHINE_OBJECTS.
4185 2012-10-08 Daniel Colascione <dancol@dancol.org>
4187 * image.c: Permanent fix for JPEG compilation issue --- limit
4188 jpeglib `boolean' redefinition to Cygwin builds.
4190 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4192 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
4194 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
4197 2012-10-08 Daniel Colascione <dancol@dancol.org>
4199 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4200 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
4201 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
4202 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
4203 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
4204 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4205 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4206 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4207 now a supported configuration.
4209 * Makefile.in: consolidate image variables into LIBIMAGE; add
4210 W32_OBJ and W32_LIBS. Compile new files.
4213 (_DebPrint) declare tracing facility for W32 debugging. We need
4214 to unify tracing later.
4216 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4217 unconditional use of W32 Unicode functions. Cygwin runs only on
4218 100% Unicode operating systems.
4220 * cygw32.c: New file. Define Cygwin-specific facilities.
4221 (Fcygwin_convert_path_to_windows)
4222 (Fcygwin_convert_path_from_windows): New user functions for
4223 accessing Cygwin path-munging routines.
4225 * cygw32.h: New file.
4226 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4227 UTF-16LE strings temporarily inside non-Lisp-visible string
4230 (w32_strerror): Just what it says on the tin.
4232 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4233 also run for Cygwin; both systems have the same problem with using
4234 GUI facilities in a forked child. Also call syms_of_cygw32,
4235 syms_of_w32select in correct places.
4237 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4238 needs fork-then-exec for daemon launching.
4240 * font.h: Include frame.h.
4242 * image.c: Use the image library cache machinery only when we're
4243 compiling for native WINDOWSNT; Cygwin can use shared libraries
4244 like any other Unixlike system.
4246 * keyboard.c: Clarify a comment regarding the input loop.
4248 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4249 functions directly instead of trying to detect at runtime that our
4250 host operating system supports them. We make this change for two
4251 reasons: Cygwin lacks support for the multibyte character
4252 conversion functions used by the legacy menu code, and Cygwin
4253 never needs to rely on non-Unicode APIs.
4255 * unexw32.c (hinst): Declare extern.
4257 * w32.c: Change header order;
4258 (w32_strerror): Move to w32fns.c because we need it for
4259 non-WINDOWSNT builds.
4261 * w32.h: Add #error macro to make sure we don't include w32.h for
4262 Cygwin builds. Remove w32select declarations.
4264 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4265 w32fns.c. w32console.c is WINDOWSNT-only.
4267 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4268 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4270 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4271 (w32_major_version, w32_minor_version, w32_build_number)
4272 (os_subtype, sound_type): Define here
4273 (w32_defined_color): Make color parameter const for consistency
4274 with other _defined_color functions.
4275 (w32_createwindow): Unconditionally call w32_init_class instead of
4276 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4277 through the code is complex and unnecessary because class
4278 registration is practically free.
4279 (w32_name_of_message): New EMACSDEBUG-only function.
4280 (Fset_message_beep): Move here
4281 (Fx_open_connection): Require that the display name for Windows be
4282 "w32" for consistency, emacsclient disambiguation, and maybe, one
4283 day, multi-window-system support.
4284 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4285 Cygwin files for W32 GUI facilities, since these clearly don't
4286 expect Cygwin names.
4287 (_DebPrint): Define.
4288 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4289 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4290 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4291 (w32_last_error): Remove.
4293 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4295 * w32heap.c (syspage_mask): Declare here.
4296 (cache_system_info): Remove.
4298 * w32inevt.c (faked_key): Define globally, not statically.
4299 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4300 (w32_console_toggle_lock_key): Move to w32fns.c.
4302 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4304 * w32proc.c (_DebPrint): Move to w32fns.c.
4305 * w32select.c: Include string.h, stdio.h for Cygwin.
4306 * w32select.h: New File.
4308 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4310 (w32_message_fd): New variable. Under Cygwin, holds the file
4311 descriptor the system used to tell us about pending thread
4314 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4315 that prevented compilation under non-WINDOWSNT systems.
4317 (w32_initialize): Open /dev/windows and assign it to
4318 w32_message_fd. Provide w32 feature.
4320 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4321 (WM_EMACS_INPUT_READY): add.
4322 (prepend_msg, w32_message_fd): Declare globally.
4325 (keyboard_handle): Use only when WINDOWSNT.
4326 (notify_msg_ready): New function. Posts a message to the main
4327 thread's message queue under CYGWIN, which wakes up the main
4328 thread from select(2) by making the /dev/windows file descriptor
4329 ready. Under WINDOWSNT, it sets an event the same way the old
4332 (post, prepend_msg): Actually call notify_msg_ready instead of
4333 setting the input event directly.
4335 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4337 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4338 but it still has blocs in it, don't return it to the system,
4339 instead of aborting. (Bug#12402)
4341 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4343 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4345 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4346 MAC_OS_X_VERSION_10_6.
4347 (syms_of_nsterm): Remove comment about Panther and above for
4349 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
4350 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
4351 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4353 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4354 MAC_OS_X_VERSION_10_4.
4356 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4357 MAC_OS_X_VERSION_10_2.
4359 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4361 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4362 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4364 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4365 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4366 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4367 Remove ns_in_resize check.
4368 (ns_clear_frame_area): Remove resize handle code.
4370 * nsfns.m (ns_in_resize): Remove.
4371 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4372 Remove ns_in_resize check.
4374 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4376 Improve sys_siglist detection.
4377 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4378 defined as a macro, as is done in Solaris.
4379 (sys_siglist_entries): New macro.
4380 (save_strsignal): Use it.
4381 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4382 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4384 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4386 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4387 fullscreen/Fullscreen.
4389 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4390 tobar_height is new.
4392 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4393 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4394 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4395 (windowDidResize:): Check for correct window if old style fullscreen.
4396 Capitalize word in comment. Remove incorrect comment.
4397 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4398 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4399 error in drawing background.
4400 (toggleFullScreen:): Remove comment. Rearrange calls.
4401 Set toolbar values to zero, save old height in tobar_height.
4402 Restore tool bar height when leaving fullscreen.
4403 (canBecomeMainWindow): New function.
4405 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4407 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4409 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4411 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4413 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4414 that time stamps of directories could also be changed.
4415 Don't request the too broad GENERIC_WRITE, only the more restrictive
4416 FILE_WRITE_ATTRIBUTES access rights.
4418 * fileio.c (Fset_file_times): Special-case ignoring errors for
4419 directories only on MSDOS, not on MS-Windows.
4421 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4423 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4425 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4427 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4428 see whether CreateFile failed.
4430 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4432 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4433 to avoid similar races.
4434 * keyboard.c (pending_signals): Now bool, not int.
4436 Port timers to OpenBSD, plus check for timer failures.
4437 OpenBSD problem reported by Han Boetes.
4438 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4440 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4441 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4442 like OpenBSD, which has timer_settime but does not declare it.
4443 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4444 whether to use itimerspec-related primitives. All uses of
4445 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4447 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4449 * profiler.c (handle_profiler_signal): Fix a malloc race
4450 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4452 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4454 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4456 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4458 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4459 consistent with the change in return value of 'safe_strsignal'.
4461 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4463 Prefer plain 'static' to 'static inline' (Bug#12541).
4464 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4465 (bidi_set_sor_type, bidi_push_embedding_level)
4466 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
4467 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
4468 (bidi_cache_search, bidi_cache_ensure_space)
4469 (bidi_cache_iterator_state, bidi_cache_find)
4470 (bidi_peek_at_next_level, bidi_set_paragraph_end)
4471 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4472 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4473 Now 'static', not 'static inline'.
4475 Count overruns when profiling; change units to ns.
4476 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4477 Give extra weight to samples after overruns, to attempt to count
4478 the time more accurately.
4479 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4480 the underlying primitives nominally do ns.
4481 (Fprofiler_cpu_start): Document the change. Mention that
4482 the sampling intervals are only approximate.
4484 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4486 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4488 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4489 case for the special 0 coding-system.
4491 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4492 (Fmake_overlay): Remove redundant tests.
4493 (fix_start_end_in_overlays): Remove redundant recentering.
4495 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4497 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4498 Update dependencies.
4500 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4502 Fix a malloc race condition involving strsignal.
4503 A signal can arrive in the middle of a malloc, and Emacs's signal
4504 handler can invoke strsignal, which can invoke malloc, which is
4505 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4506 Fix it by altering the signal handler so that it does not invoke
4508 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4509 * process.c (status_message): Use const pointer, in case strsignal
4510 is #defined to safe_strsignal.
4511 * sysdep.c (sys_siglist, init_signals): Always define and
4512 initialize a substitute sys_siglist if the system does not define
4513 one, even if HAVE_STRSIGNAL.
4514 (safe_strsignal): Rename from strsignal. Always define,
4515 using sys_siglist. Return a const pointer.
4516 * syssignal.h (safe_strsignal): New decl.
4517 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4519 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4521 * w32proc.c (timer_loop): Fix code that waits for timer
4522 expiration, to avoid high CPU usage.
4524 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4526 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4527 (sweep_weak_table): Remove redundant prototypes.
4529 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4531 * emacs.c: Move the inclusion of TERM_HEADER after including
4532 windows.h on WINDOWSNT. This avoids compilation problems with
4535 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4537 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4538 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4539 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4540 as the previous version used 'void *'.
4542 * ralloc.c (ROUNDUP): Fix last change.
4543 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4546 * w32proc.c <disable_itimers>: New static flag.
4547 (init_timers): Initialize it to zero, after creating the critical
4548 sections used by the timer threads.
4549 (term_timers): Set to 1 before deleting the critical sections.
4550 (getitimer, setitimer): If disable_itimers is non-zero, return an
4551 error indication without doing anything. Reported by Fabrice
4552 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4553 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4555 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4558 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4559 term_ntproc after all the other bookkeeping, to get timers working
4560 as long as possible.
4562 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4564 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4565 Suggested by Juri Linkov in
4566 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4568 Prefer plain 'static' to 'static inline' (Bug#12541).
4569 With static functions, modern compilers inline pretty well by
4570 themselves; advice from programmers often hurts as much as it helps.
4571 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4572 this change shrinks the text size of the Emacs executable by 1.1%
4573 without affecting CPU significantly in my benchmark.
4574 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

4867 (handle_profiler_signal): Rename from sigprof_handler_1,
4868 for consistency with other handlers. Do not check whether
4869 cpu_log is a hash-table if garbage collecting, since it

4872 for consistency with other handlers.
4873 (setup_cpu_timer): New function, with much of what used to be in

4875 Prefer timer_settime if available, and prefer
4876 thread cputime clocks, then process cputime clocks, then
4877 monotonic clocks, to the old realtime clock. Use make_timeval
4878 to round more-correctly when falling back to setitimer.
4879 (Fprofiler_cpu_start): Use it.
4880 (Fprofiler_cpu_stop): Prefer timer_settime if available.

4887 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4888 in profiler.c, since sysdep.c now uses it.
4890 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

4946 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4947 Since this stuff is now private to charset.c, there's no need for
4948 a public macro and no need to inline by hand.

5028 install term_ntproc as a signal handler for SIGABRT, as that
5029 should be done by the dumped Emacs.

5096 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5098 Move pid_t related decls out of lisp.h.
5099 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
5100 (interruptible_wait_for_termination):
5101 Move these decls from lisp.h to syswait.h, since they use pid_t.
5102 Needed on FreeBSD; see Herbert J. Skuhra in
5103 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
5104 * callproc.c: Include syswait.h.

5150 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5152 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5153 fatal_error_backtrace.
5155 * w32proc.c (sys_kill): Undo last change: don't do anything when
5156 invoked to deliver SIGABRT to our own process. This is now
5157 handled by emacs_raise.
5159 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5161 * w32term.c (w32_read_socket): Remove leftover reference to
5162 interrupt_input_pending.
5164 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5166 Do not use SA_NODEFER.
5167 Problem reported by Dani Moncayo in
5168 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5170 * sysdep.c (emacs_abort): Do not reset signal handler.
5171 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5172 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5173 wanted even on POSIXish hosts, and it doesn't work on Windows.
5175 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5177 * xterm.c (x_term_init): Call fixup_locale before and after calling
5178 gtk_init (Bug#12392).
5180 2012-09-23 Chong Yidong <cyd@gnu.org>
5182 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5183 Vdynamic_library_alist.
5185 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5186 (Fgnutls_available_p): Caller changed.
5188 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5189 (Flibxml_parse_xml_region): Likewise.
5191 * dispextern.h (struct image_type): Remove arg from init function.
5193 * image.c (Finit_image_library, lookup_image_type)
5194 (define_image_type): Remove now-unneeded second arg.
5195 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5196 (init_tiff_functions, init_gif_functions, init_svg_functions):
5197 Arglist and w32_delayed_load calling convention changed.
5198 (gs_type): Remove init_gs_functions; there is no such function.
5199 (valid_image_p, make_image): Fix caller to lookup_image_type.
5201 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5203 Simplify and avoid signal-handling races (Bug#12471).
5205 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5206 Avoid recursive loop if there's a fatal error in the function itself.
5207 * atimer.c (pending_atimers):
5208 * blockinput.h: Don't include "atimer.h"; no longer needed.
5209 (interrupt_input_pending): Remove. All uses removed.
5210 pending_signals now counts both atimers and ordinary interrupts.
5211 This is less racy than having three separate pending-signal flags.
5212 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5214 Rename from their upper-case counterparts BLOCK_INPUT,
5215 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5216 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5217 This makes it easier to access volatile variables more accurately.
5218 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5219 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5220 that's more reliable if the code is buggy and sets
5221 interrupt_input_blocked to a negative value. All uses changed.
5222 * atimer.c (deliver_alarm_signal):
5223 Remove. No need to deliver this to the parent; any thread can
5224 handle this signal now. All uses replaced by underlying handler.
5225 * atimer.c (turn_on_atimers):
5226 * dispnew.c (handle_window_change_signal):
5227 * emacs.c (handle_danger_signal):
5228 * keyboard.c (kbd_buffer_get_event):
5229 Don't reestablish signal handler; not needed with sigaction.
5230 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5232 Rework to avoid unnecessary accesses to volatile variables.
5233 (UNBLOCK_INPUT_TO): Now a function.
5234 (totally_unblock_input, unblock_input): New decls.
5235 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5236 (init_data): Remove. Necessary stuff now done in init_signal.
5237 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5238 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5239 (fatal_error_code): Remove; no longer needed.
5240 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5241 it doesn't always backtrace. All uses changed. No need to reset
5242 signal to default, since sigaction and/or die does that for us now.
5243 Use emacs_raise (FOO), not kill (getpid (), FOO).
5244 (main): Check more-accurately whether we're dumping.
5245 Move fatal-error setup to sysdep.c
5246 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5247 * gtkutil.c (xg_get_file_name, xg_get_font):
5248 Remove no-longer-needed signal-mask manipulation.
5249 * keyboard.c, process.c (POLL_FOR_INPUT):
5250 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5251 * keyboard.c (read_avail_input): Remove.
5252 All uses replaced by gobble_input.
5253 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5254 (kbd_buffer_store_event_hold, gobble_input):
5255 (record_asynch_buffer_change) [USABLE_SIGIO]:
5256 (store_user_signal_events):
5257 No need to mess with signal mask.
5258 (gobble_input): If blocking input and there are terminals, simply
5259 set pending_signals to 1 and return. All hooks changed to not
5260 worry about whether input is blocked.
5261 (process_pending_signals): Clear pending_signals before processing
5262 them, in case a signal comes in while we're processing.
5263 By convention callers now test pending_signals before calling us.
5264 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5265 New functions, to support changes to blockinput.h.
5266 (handle_input_available_signal): Now extern.
5267 (reinvoke_input_signal): Remove. All uses replaced by
5269 (quit_count): Now volatile, since a signal handler uses it.
5270 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5271 All callers changed. Block SIGINT only if not already blocked.
5272 Clear sigmask reliably, even if Fsignal returns, which it can.
5273 Omit unnecessary accesses to volatile var.
5274 (quit_throw_to_read_char): No need to restore sigmask.
5275 * keyboard.c (gobble_input, handle_user_signal):
5276 * process.c (wait_reading_process_output):
5277 Call signal-handling code rather than killing ourselves.
5278 * lisp.h: Include <float.h>, for...
5279 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5280 (pending_signals): Now volatile.
5281 (syms_of_data): Now const if IEEE floating point.
5282 (handle_input_available_signal) [USABLE_SIGIO]:
5283 (terminate_due_to_signal, record_child_status_change): New decls.
5284 * process.c (create_process): Avoid disaster if memory is exhausted
5285 while we're processing a vfork, by tightening the critical section
5287 (send_process_frame, process_sent_to, handle_pipe_signal)
5288 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5290 (send_process): No need for setjmp/longjmp any more, since the
5291 SIGPIPE stuff is now gone. Instead, report an error if errno
5293 (record_child_status_change): Now extern. PID and W are now args.
5294 Return void, not bool. All callers changed.
5295 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5296 Remove. All uses removed. This bug should be fixed now in a
5298 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5299 and record the child status change directly. This avoids the
5300 need to futz with the signal mask.
5301 (process_fatal_action): Move here from emacs.c.
5302 (emacs_sigaction_flags): New function, containing
5303 much of what used to be in emacs_sigaction_init.
5304 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5305 caught by emacs, to make races less likely.
5306 (deliver_process_signal): Rename from handle_on_main_thread.
5308 (BACKTRACE_LIMIT_MAX): Now at top level.
5309 (thread_backtrace_buffer, threadback_backtrace_pointers):
5311 (deliver_thread_signal, deliver_fatal_thread_signal):
5312 New functions, for more-accurate delivery of thread-specific signals.
5313 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5314 (deliver_arith_signal): Handle in this thread, not
5315 in the main thread, since it's triggered by this thread.
5316 (maybe_fatal_sig): New function.
5317 (init_signals): New arg DUMPING so that we can be more accurate
5318 about whether we're dumping. Caller changed.
5319 Treat thread-specific signals differently from process-general signals.
5320 Block all signals while handling fatal error; that's safer.
5321 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5323 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5324 Ignore SIGPIPE unless batch.
5325 (emacs_backtrace): Output backtrace for the appropriate thread,
5326 which is not necessarily the main thread.
5327 * syssignal.h: Include <stdbool.h>.
5328 (emacs_raise): New macro.
5329 * xterm.c (x_connection_signal): Remove; no longer needed
5330 now that we use sigaction.
5331 (x_connection_closed): No need to mess with sigmask now.
5332 (x_initialize): No need to reset SIGPIPE handler here, since
5333 init_signals does this for us now.
5335 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5337 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5338 background rect may be larger (Bug#12245).
5340 2012-09-23 Chong Yidong <cyd@gnu.org>
5342 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5344 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5346 * .gdbinit: Just stop at fatal_error_backtrace.
5347 See Stefan Monnier's request in
5348 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5349 Remove no-longer-used query of system type.
5351 2012-09-22 Chong Yidong <cyd@gnu.org>
5353 * search.c (Freplace_match): Doc fix (Bug#12325).
5355 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5357 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5358 (Fline_end_position): Doc fix.
5360 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5362 2012-09-22 Chong Yidong <cyd@gnu.org>
5364 * dispextern.h (struct image_type): Add new slot, storing a type
5365 initialization function.
5367 * image.c (define_image_type): Call the image initializer function
5368 if it is defined. Arguments and return value changed.
5369 (valid_image_p, make_image): Callers changed.
5370 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5371 (gif_type, imagemagick_type, svg_type, gs_type):
5372 Add initialization functions.
5373 (Finit_image_library): Call lookup_image_type.
5374 (CHECK_LIB_AVAILABLE): Macro deleted.
5375 (lookup_image_type): Call define_image_type here, rather than via
5376 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5377 (syms_of_image): Move define_image_type calls for xbm_type and
5378 pbm_type to lookup_image_type.
5380 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5382 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5383 'idle_timers' from here ...
5384 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5385 lists, to avoid infloops when the timer does something stupid,
5386 like reinvoke itself with the same or smaller time-out.
5389 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5391 * window.c (Fsplit_window_internal): Handle only Qt value of
5392 Vwindow_combination_limit separately.

5400 the new overlay string. (Bug#10159)
5402 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5404 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5405 or that fprintf is async-signal-safe. POSIX doesn't require
5408 2012-09-22 Chong Yidong <cyd@gnu.org>
5410 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5413 2012-09-22 Kenichi Handa <handa@gnu.org>
5415 * composite.c (composition_reseat_it): Handle the case that a
5416 grapheme cluster is not covered by a single font (Bug#12352).
5418 2012-09-21 Chong Yidong <cyd@gnu.org>
5420 * image.c (define_image_type): Avoid adding duplicate types to
5421 image_types (Bug#12463). Suggested by Jörg Walter.
5423 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5425 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5426 (print_load_command_name): Add case LC_DATA_IN_CODE.
5427 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.

5431 * eval.c (Frun_hook_with_args_until_success)
5432 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5434 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5436 * fileio.c (Ffile_selinux_context): Only call freecon when
5437 lgetfilecon succeeded.
5438 (Fset_file_selinux_context): Likewise. (Bug#12444)
5440 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5442 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5443 reordering, locate the cursor by calling set_cursor_from_row; if
5444 that fails, clear the desired glyph matrix before returning a
5445 failure indication to the caller. Fixes leaving garbled display
5446 when fast scrolling with a down-key. (Bug#12403)
5447 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5448 scrolling through multibyte text.
5450 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5452 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5453 calling mark_vectorlike since that's the one that marks the window.
5454 (mark_discard_killed_buffers): Mark the final cdr.
5455 * window.h (struct window): Move prev/next_buffers to the
5456 non-standard fields.
5457 * window.c (make_window): Initialize prev/next_buffers manually.
5459 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5461 Omit unused arg EXPECTED from socket hooks.
5462 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):

5464 * termhooks.h (struct terminal.read_socket_hook):
5465 * w32inevt.c (w32_console_read_socket):
5466 * w32term.c (w32_read_socket):
5467 * xterm.c (XTread_socket):
5468 Omit unused arg EXPECTED. All callers changed.
5469 (store_user_signal_events): Return void, not int, since callers no
5470 longer care about the return value. All uses changed.
5472 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5474 * w32gui.h (XParseGeometry): Do not declare.
5476 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5478 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5479 Ignore 'expected'. See Eli Zaretskii in

5482 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5483 (XParseGeometry): Now static. Substitute extremal values for
5484 values that are out of range.
5486 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5488 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5490 * nsfns.m (XParseGeometry): Remove.
5491 (Fx_create_frame): Call x_set_offset to correctly interpret
5492 top_pos in geometry.
5494 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5495 (Fx_parse_geometry): If there is a space in string, call
5496 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5498 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5500 * search.c (scan_buffer): Use character positions in calls to
5501 region_cache_forward and region_cache_backward, not byte
5502 positions. (Bug#12196)
5504 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5505 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5507 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5508 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5509 emacs_blocked_malloc, now deleted.
5511 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5513 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5514 The workaround was for improving performance on Solaris 2.4, but
5515 is getting in the way now. Emacs will still work if someone is
5516 still running Solaris 2.4 in a museum somewhere; Sun dropped
5517 support for Solaris 2.4 in 2003.
5518 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5519 * process.c (create_process) [HAVE_WORKING_VFORK]:
5520 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5521 since Emacs no longer uses vfork on that platform.
5523 2012-09-17 Glenn Morris <rgm@gnu.org>
5525 * emacs.c: Use COPYRIGHT.
5527 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5529 Remove configure's --without-sync-input option (Bug#12450).
5530 When auditing signal-handling in preparation for cleaning it up,
5531 I found that SYNC_INPUT has race conditions and would be a real
5532 pain to fix. Since it's an undocumented and deprecated
5533 configure-time option, now seems like a good time to remove it.
5534 Also see <http://bugs.gnu.org/11080#16>.
5535 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5536 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5537 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5538 (malloc_hysteresis):
5539 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5540 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5541 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5542 (dont_register_blocks, bytes_used_when_reconsidered)
5543 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5544 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5545 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5546 Remove. All uses removed.
5547 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5548 implementation, one that depends on whether the new macro
5549 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5551 * atimer.c (run_timers, handle_alarm_signal):
5552 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5553 (handle_async_input, process_pending_signals)
5554 (handle_input_available_signal, init_keyboard):
5555 * nsterm.m (ns_read_socket):
5556 * process.c (wait_reading_process_output):
5557 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5558 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5560 * xterm.c (XTread_socket):
5562 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5563 * eval.c (handling_signal): Remove. All uses removed.
5564 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5565 All uses replaced with the SYNC_INPUT version.
5566 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5568 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5571 * font.c (Ffont_shape_gstring): Remove unused local.
5573 2012-09-16 Glenn Morris <rgm@gnu.org>
5575 * Makefile.in (clean): No longer run nextstep's clean.
5577 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5579 (ns-app): Move here from ns.mk, and simplify.
5580 (clean): Simplify nextstep entry.
5581 * ns.mk: Remove file.
5583 2012-09-17 Kenichi Handa <handa@gnu.org>
5585 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5586 not covert the last few charactes.
5588 2012-09-16 Kenichi Handa <handa@gnu.org>
5590 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5591 here, but just check the validity of glyphs in the glyph-string.
5593 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5595 * window.c (Fwindow_parameter, Fset_window_parameter):
5596 Accept any window as argument (Bug#12452).
5598 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5600 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5601 to ns_term_init to avoid memory leak.
5603 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5604 explicit retain/release.
5605 (ns_term_init): Only allow one display. Initialize outerpool and
5608 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5610 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5611 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5612 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5613 the Microsoft problem in a different way, by altering ../nt/config.nt.
5615 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5630 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5631 by lisp.h. This completes removal of setjmp.h inclusion
5632 erroneously announced in the previous commit. (Bug#12446)
5634 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5637 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5638 not defined as a macro. The latter happens on MS-Windows.
5641 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5643 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5644 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5645 Some instances of '#include <setjmp.h>' removed, if the
5646 only reason for the instance was because "lisp.h" was included.
5647 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5648 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5649 and _longjmp with the new symbols. Emacs already uses _setjmp if
5650 available, so this change affects only POSIXish hosts that have
5651 sigsetjmp but not _setjmp, such as some versions of Solaris and
5652 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5653 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5654 (png_load_body) [HAVE_PNG]:
5655 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5656 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5657 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5658 since PNG requires jmp_buf. This is the only exception to the
5659 general rule that we now use sys_setjmp and sys_longjmp.
5660 This exception is OK since this code does not change the signal
5661 mask or longjmp out of a signal handler.
5663 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5665 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5666 Include "syssignal.h", for 'main_thread'.
5668 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5670 Avoid out-of-range marker position (Bug#12426).
5671 * insdel.c (replace_range, replace_range_2):
5672 Adjust markers before overlays, as suggested by comments.
5673 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5674 Remove redundant check before calling offset_intervals.
5676 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5678 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5679 current buffer (Bug#12387).
5681 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5683 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5685 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5687 Use a more backwards-compatible timer format (Bug#12430).
5688 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5689 vector element, not from the 4th, since PSECS is now at the end.
5690 (Fcurrent_idle_time): Doc fix.
5692 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5694 Function to mark objects and remove killed buffers at once.
5695 * alloc.c (discard_killed_buffers): Rename to ...
5696 (mark_discard_killed buffers) ... new name. Add marking
5697 of remaining objects. Fix comment. Adjust users.
5698 (mark_object): Do not touch frame buffer lists here.
5699 * frame.c (delete_frame): Reset frame buffer lists here.
5701 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5703 Better workaround for GNOME bug when --enable-gcc-warnings.
5704 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5705 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5706 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5708 Simplify SIGIO usage (Bug#12408).
5709 The code that dealt with SIGIO was crufty and confusing, e.g., it
5710 played tricks like "#undef SIGIO" but these tricks were not used
5711 consistently. Simplify mostly by not #undeffing standard symbols,
5712 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5713 or not as we please) rather than "defined SIGIO" (standard symbol
5714 that we probably shouldn't #undef).
5715 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5716 Modules that need it can include it.
5717 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5718 * dispextern.h (ignore_sigio): New decl.
5719 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5720 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5721 * emacs.c (shut_down_emacs):
5722 * keyboard.c (kbd_buffer_store_event_hold):
5723 Use ignore_sigio rather than invoking 'signal' directly.
5724 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5726 (FIONREAD, SIGIO): Do not #undef.
5727 (tty_read_avail_input): Use #error rather than a syntax error.
5728 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5729 for I_PIPE, used by SETUP_SLAVE_PTY.
5730 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5731 * sysdep.c (croak): Remove; no longer needed. This bit of
5732 temporary code, with Fred N. Fish's comment that it's temporary,
5733 has been in Emacs since at least 1992!
5734 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5735 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5736 * syssignal.h (croak): Remove decl.
5737 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5738 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5739 now that we're termios-only.
5740 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5741 * term.c (dissociate_if_controlling_tty): Use #error rather than
5744 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5745 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5746 to work around GNOME bug 683906.
5747 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5748 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5749 This works around GCC bug 54561.
5751 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5753 More fixes for 'volatile' and setjmp/longjmp.
5754 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5755 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5756 (png_load_body) [HAVE_PNG]:
5757 (jpeg_load_body) [HAVE_JPEG]:
5758 New function, with most of the old parent function's body.
5759 (png_load) [HAVE_PNG]:
5760 (jpeg_load) [HAVE_JPEG]:
5761 Invoke the new function, to avoid longjmp munging our locals.
5762 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5763 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5764 longjmp is passed 2, as the C standard doesn't guarantee this.
5765 Instead, store the failure code into mgr->failure_code.
5767 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5769 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5770 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5771 (syms_of_keyboard): Remove support for unread-command-char.
5773 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5775 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5776 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5777 violation. (Bug#12426)
5779 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5781 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5783 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5785 * eval.c: Add `inhibit-debugger'.
5786 (Qinhibit_debugger): New symbol.
5787 (call_debugger): Bind it instead of Qdebug_on_error.
5788 (maybe_call_debugger): Test Vinhibit_debugger.
5789 (syms_of_eval): Define inhibit-debugger.
5790 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5791 (syms_of_xdisp): Remove inhibit-debug-on-message.
5793 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5795 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5796 If a nonvolatile local variable is written before a _longjmp to
5797 the frame containing the variable, and is read after the _longjmp,
5798 the value read is indeterminate. Some local variables of type
5799 'struct handler' and 'struct catchtag' are used in this way, so
5800 mark each of their slots as volatile if the slot can be set before
5801 _longjmp and read afterwards.
5802 * lisp.h (struct handler): var and chosen_clause are now volatile.
5803 (struct catchtag): val, next, and pdlcount are now volatile.
5805 * bidi.c (bidi_push_it, bidi_pop_it):
5806 * fns.c (copy_hash_table):
5807 * image.c (define_image_type):
5808 * keyboard.c (kbd_buffer_store_event_hold):
5809 * process.c (Fprocess_send_eof):
5810 * xfaces.c (x_create_gc) [HAVE_NS]:
5811 * xgselect.c (xg_select):
5812 Prefer assignment to memcpy when either will do.
5814 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5815 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5816 time an item is removed. No need to mark this function 'inline';
5817 the compiler knows better than we do.
5819 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5821 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5822 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5823 to change_frame_size (Bug#12388).
5824 (windowDidResize:): Pass YES to updateFrameSize.
5826 * nsterm.h: Add delay parameter to updateFrameSize.
5828 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5830 Discard killed buffers from deleted window and frame objects.
5831 This reduces an amount of references to killed buffers and
5832 helps GC to reclaim them faster.
5833 * alloc.c (discard_killed_buffers): New function.
5834 (mark_object): Use it for deleted windows and frames.
5835 (mark_object): If symbol's value is set up for a killed buffer
5836 or deleted frame, restore its global binding.
5837 * data.c (swap_in_global_binding): Add GC notice.
5838 (swap_in_symval_forwarding): Use convenient set_blv_where.
5839 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5840 * window.h: ... to here.
5842 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5844 Convenient macro to check whether the buffer is live.
5845 * buffer.h (BUFFER_LIVE_P): New macro.
5846 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5847 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5849 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5851 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5852 composition cases (Bug#12364).
5854 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5855 overhang of succeeding glyphs overlapping box cursor.
5857 * w32term.c (x_draw_glyph_string): Likewise.
5859 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5861 Simplify, document, and port floating-point (Bug#12381).
5862 The porting part of this patch fixes bugs on non-IEEE platforms
5863 with frexp, ldexp, logb.
5864 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5866 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5867 support, by removing commented-out code and briefly listing the
5868 C89 functions excluded. The commented-out stuff was confusing
5869 maintenance, e.g., we thought we needed cbrt but it was commented out.
5870 (logb): Remove decl; no longer needed.
5871 (isfinite): New macro, if not already supplied.
5872 (isnan): Don't replace any existing macro.
5873 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5874 are present on all C89 platforms.
5875 (Ffrexp): Do not special-case zero, as frexp does the right thing
5877 (Flogb): Do not use logb, as it doesn't have the desired meaning
5878 on hosts that use non-base-2 floating point. Instead, stick with
5879 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5880 frexp, to avoid getting an unspecified result.
5882 * xdisp.c (Qinhibit_debug_on_message): Now static.
5884 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5886 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5887 NSBezierPath (Bug#12131).
5889 2012-09-10 Chong Yidong <cyd@gnu.org>
5891 * fns.c (Fdelq, Fdelete): Doc fix.
5893 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5895 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5896 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5898 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5900 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5901 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5904 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5906 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5907 left fringe if the window has a left margin. This avoids leaving
5908 traces of the cursor because its leftmost pixel is not drawn over.
5910 * dispnew.c (update_window_line): When the left margin area of a
5911 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5912 that screen line. (Bug#12277)
5914 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5916 Assume C89 or later for math functions (Bug#12381).
5917 This simplifies the code, and makes it a bit smaller and faster,
5918 and (most important) makes it easier to clean up signal handling
5919 since we can stop worring about floating-point exceptions in
5920 library code. That was a problem before C89, but the problem
5921 went away many years ago on all practical Emacs targets.
5922 * data.c, image.c, lread.c, print.c:
5923 Don't include <math.h>; no longer needed.
5924 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5925 might be autoconfigured, as that never happens.
5927 * doprnt.c (DBL_MAX_10_EXP):
5928 * print.c (DBL_DIG):
5929 Remove. C89 or later always defines these.
5930 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5931 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5932 (arith_error, domain_error, domain_error2):
5933 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5934 no longer needed -- we simply return what C returns. All uses removed.
5935 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5937 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5938 Remove. All uses expanded, as these macros are no longer used
5939 more than once and are now more trouble than they're worth.
5940 (Ftan): Use tan, not sin / cos.
5941 (Flogb): Assume C89 frexp.
5942 (fmod_float): Assume C89 fmod.
5943 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5944 (init_floatfns): Remove. All uses removed.
5946 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5948 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5949 compositeToPoint for OSX < 10.6 (Bug#12390).
5951 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5953 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5954 This produces more-accurate results.
5956 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5958 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5959 changes (Bug#12088).
5961 2012-09-08 Chong Yidong <cyd@gnu.org>
5963 * syntax.c (Fstring_to_syntax): Doc fix.
5965 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5967 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5968 in the internal border.
5969 (x_set_window_size): Remove static variables and their usage.
5970 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5971 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5972 Remove fringe/internal border adjustment (Bug#11052).
5973 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5974 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5975 (ns_fix_rect_ibw): Remove.
5976 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5977 (ns_dumpglyphs_box_or_relief): Ditto.
5978 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5980 (ns_dumpglyphs_image): Ditto.
5981 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5983 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5984 their usage. Add fringe_extended_p and its use as in other terms.
5985 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5986 scroll bar was removed.
5987 (updateFrameSize): New function.
5988 (windowDidResize): Move code to updateFrameSize and call it.
5990 * nsterm.h (EmacsView): Add updateFrameSize.
5992 2012-09-07 Chong Yidong <cyd@gnu.org>
5994 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5996 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5998 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6000 More signal-handler cleanup (Bug#12327).
6001 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6002 Problem introduced when merging patches. Noted by Eli Zaretskii in
6003 <http://bugs.gnu.org/12327#67>.
6004 * floatfns.c: Comment fix.
6005 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6006 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6007 and anyway the declaration is harmless even if SIGDANGER is not defined.
6008 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6009 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6010 source files not surprisingly expected syssignal.h to define, or
6011 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6012 Include <sys/ioctl.h>, for FIONREAD.
6013 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6014 This eliminates a problem whereby other files mysteriously had
6015 to include "syssignal.h" before including "systty.h" if they
6016 wanted to use "#ifdef SIGIO".
6018 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6020 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6022 * w32.c (sigemptyset): Empty the set.
6023 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6025 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6027 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6029 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6030 (mark_object): Likewise for frame objects.
6032 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6034 * syssignal.h (handle_on_main_thread): Always declare,
6035 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6036 This ports to platforms without HAVE_PTHREAD.
6038 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6040 Signal-handler cleanup (Bug#12327).
6041 Emacs's signal handlers were written in the old 4.2BSD style with
6042 sigblock and sigmask and so forth, and this led to some
6043 inefficiencies and confusion. Rewrite these to use
6044 pthread_sigmask etc. without copying signal sets around. Also,
6045 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6046 'signal', and instead use functions that do not attempt to take
6047 over the system name space. This patch causes Emacs's text
6048 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6049 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6050 Do not include <signal.h> or "syssignal.h", as these
6051 modules do not use signals.
6052 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6053 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6054 Do not include <signal.h>, as "syssignal.h" does that for us now.
6055 * atimer.c (sigmask_atimers): New function.
6056 (block_atimers, unblock_atimers): New functions,
6057 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6059 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6060 no longer needed here.
6061 * emacs.c (main): Inspect existing signal handler with sigaction,
6062 so that there's no need to block and unblock SIGHUP.
6063 * sysdep.c (struct save_signal): New member 'action', replacing
6064 old member 'handler'.
6065 (save_signal_handlers, restore_signal_handlers):
6066 Use sigaction instead of 'signal' to save and restore.
6067 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6068 New function. All users of 'signal' modified to use set_sighandler
6069 if they're writeonly, and to use sys_signal if they're read+write.
6070 (emacs_sigaction_init, forwarded_signal): New functions.
6071 (sys_signal): Remove. All uses replaced by calls to sigaction
6072 and emacs_sigaction_init, or by direct calls to 'signal'.
6073 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6074 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6075 all uses replaced by pthread_sigmask etc. calls.
6076 * syssignal.h: Include <signal.h>.
6077 (emacs_sigaction_init, forwarded_signal): New decls.
6078 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6079 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6080 (sigmask, sys_sigmask): Remove; no longer needed.
6081 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6082 (sigblock, sigunblock, sigfree):
6083 (sigsetmask) [!defined sigsetmask]:
6084 Remove. All uses replaced by pthread_sigmask.
6085 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6086 no longer need to be replaced, and its typical old uses
6087 are now done via emacs_sigaction_init and sigaction.
6088 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6089 (sys_sigdel): Remove; unused.
6090 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6092 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6094 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6095 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6097 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6099 Explicitly mark buffer_defaults and buffer_local_symbols.
6100 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6101 mark_local_symbols here.
6102 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6103 since special buffers aren't marked here any more.
6104 (allocate_buffer): Chain new buffer with all_buffers here...
6105 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6107 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6108 (syms_of_buffer): Remove staticpro of the above.
6109 (init_buffer_once): Set names for buffer_defaults and
6110 buffer_local_symbols.
6112 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6114 Use bool for booleans in font-related modules.
6115 * font.c (font_intern_prop, font_style_to_value)
6116 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6117 (generate_otf_features, font_check_otf_features, font_check_otf)
6118 (font_match_p, font_list_entities, font_at):
6119 * fontset.c (fontset_id_valid_p, reorder_font_vector
6120 (fontset_find_font, Fset_fontset_font)
6121 (face_suitable_for_char_p) [0]:
6122 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6123 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6124 (m17n_flt_initialized, ftfont_shape_by_flt):
6125 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6126 * nsfont.m (nsfont_draw):
6127 * w32font.c (w32font_draw):
6128 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6129 Use bool for booleans.
6130 * font.h: Adjust to above API changes.
6131 (struct font, struct font_driver, struct font_driver_list):
6132 Use bool for booleans.
6133 (struct font): Remove useless member encoding_type.
6135 * fontset.c, xftfont.c: Omit unnecessary static decls.
6137 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6139 * alloc.c (mark_object): Revert window marking code
6140 since it's unsafe for the Fset_window_configuration.
6142 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6144 Fix race conditions with signal handlers and errno (Bug#12327).
6145 Be more systematic about preserving errno whenever a signal
6146 handler returns, even if it's not in the main thread. Do this by
6147 renaming signal handlers to distinguish between signal delivery
6148 and signal handling. All uses changed.
6149 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6150 * data.c (deliver_arith_signal): Rename from arith_error.
6151 * dispnew.c (deliver_window_change_signal): Rename from
6152 window_change_signal.
6153 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6154 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6155 * keyboard.c (deliver_input_available_signal): Rename from
6156 input_available_signal.
6157 (deliver_user_signal): Rename from handle_user_signal.
6158 (deliver_interrupt_signal): Rename from interrupt_signal.
6159 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6160 (deliver_child_signal): Rename from sigchld_handler.
6161 * atimer.c (handle_alarm_signal):
6162 * data.c (handle_arith_signal):
6163 * dispnew.c (handle_window_change_signal):
6164 * emacs.c (handle_fatal_signal, handle_danger_signal):
6165 * keyboard.c (handle_input_available_signal):
6166 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6167 * process.c (handle_pipe_signal, handle_child_signal):
6168 New functions, with the actual signal-handling code taken from the
6169 original respective signal handlers, sans the sporadic attempts to
6170 preserve errno, since that's now done by handle_on_main_thread.
6171 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6172 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6173 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6175 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6176 Move initialization of main_thread to sysdep.c's init_signals.
6177 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6178 our usage, and simplifies the mainline code.
6179 (record_child_status_change): New static function, as a helper
6180 for handle_child_signal, and with most of the old child handler's
6182 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6183 (handle_child_signal): Use the above.
6184 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6185 Moved here from emacs.c.
6186 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6187 code moved here from emacs.c's main function.
6188 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6189 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6190 This lets callers save and restore errno properly.
6192 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6194 Remove redundant or unused things here and there.
6195 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6196 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6197 * editfns.c (Fcompare_buffer_substrings): Likewise.
6198 * frame.h (struct terminal, struct font_driver_list):
6199 Remove redundant declarations.
6200 * window.h (Qleft, Qright): Likewise.
6202 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6204 Do not mark objects from deleted buffers, windows and frames.
6205 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6206 (mark_object): Likewise for windows and frames.
6208 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6210 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6211 buffer_defaults and buffer_local_symbols as valid objects.
6212 Return special value to denote them.
6214 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6216 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6217 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6218 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6219 (file_name_absolute_p, Fsubstitute_in_file_name):
6220 (check_executable, check_writable, Ffile_accessible_directory_p)
6221 (Fset_file_selinux_context, Fdefault_file_modes)
6222 (Finsert_file_contents, choose_write_coding_system)
6223 (Fwrite_region, build_annotations, a_write, e_write)
6225 * filelock.c (boot_time_initialized, get_boot_time)
6226 (get_boot_time_1, lock_file_1, within_one_second):
6227 * floatfns.c (in_float):
6228 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6229 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6230 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6231 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6232 * window.c (compare_window_configurations):
6233 Use bool for booleans.
6234 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6235 (Fdefault_file_modes): Now mode_t, not int, for modes.
6236 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6237 (internal_delete_file): Now returns void, not a (boolean) int,
6238 since nobody was looking at the return value.
6239 * lisp.h, window.h: Adjust to above API changes.
6241 * xdisp.c (set_message): Simplify and reindent last change.
6243 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6245 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6247 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6249 * eval.c (call_debugger): Make the function non-static so that we
6250 can call it from set_message.
6252 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6253 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6255 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6257 Give more-useful info on a fatal error (Bug#12328).
6258 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6259 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6260 of doing the work ourselves.
6261 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6262 do most of the work.
6263 (fatal_error_backtrace): New function, taken from the guts
6264 of the old fatal_error_signal, but with a new option to output
6266 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6267 info about the signal than just its number.
6268 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6269 * sysdep.c: Include <execinfo.h>
6270 (emacs_backtrace): New function, taken partly from the previous
6271 code of the 'die' function.
6272 (emacs_abort): Call fatal_error_backtrace rather than abort.
6274 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6276 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6277 eager (load-time) macro-expansion.
6278 * lisp.mk (lisp): Add macroexp.
6280 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6282 Simplify redefinition of 'abort' (Bug#12316).
6283 Do not try to redefine the 'abort' function. Instead, redo
6284 the code so that it calls 'emacs_abort' rather than 'abort'.
6285 This removes the need for the NO_ABORT configure-time macro
6286 and makes it easier to change the abort code to do a backtrace.
6287 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6288 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6289 Remove; sysdep.c's emacs_abort now takes its place.
6290 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6291 'abort' changed to use 'emacs_abort'.
6292 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6293 (abort) [!defined abort]: Rename to ...
6294 (emacs_abort): ... new name.
6295 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6296 the place of the old 'abort' in emacs.c.
6297 * w32.c, w32fns.c (abort): Do not #undef.
6298 * w32.c (emacs_abort): Rename from w32_abort.
6300 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6302 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6303 offsets[j].dv, since the y axis of the screen coordinates points
6304 down, while the y axis of the font definition coordinates points
6305 up. This fixes display of Arabic diacritics such as KASRA and
6306 KASRATAN. (Bug#11860)
6308 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6310 Be more systematic about _setjmp vs setjmp.
6311 * alloc.c (test_setjmp, mark_stack):
6312 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
6313 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
6314 (png_load, my_error_exit, jpeg_load):
6315 * process.c (send_process_trap, send_process):
6316 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6317 The underscored versions are up to 30x faster on some hosts.
6318 Formerly, the code used setjmp+longjmp sometimes and
6319 _setjmp+_longjmp at other times, with no particular reason to
6320 prefer setjmp+longjmp.
6322 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
6324 Fix minor problem found by static checking.
6325 * buffer.c (Fdelete_all_overlays): Return nil.
6327 2012-09-03 Martin Rudalics <rudalics@gmx.at>
6329 * buffer.c (Fdelete_all_overlays): New function.
6331 2012-09-03 Chong Yidong <cyd@gnu.org>
6333 * gtkutil.c: Add extern decl for Qxft.
6335 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
6337 * emacs.c, eval.c: Use bool for boolean.
6338 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
6339 (malloc_using_checking) [DOUG_LEA_MALLOC]:
6340 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
6341 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
6342 (main, decode_env_path, Fdaemon_initialized):
6343 * eval.c (call_debugger, Finteractive_p, interactive_p):
6344 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
6345 (maybe_call_debugger, Fbacktrace):
6346 * process.c (read_process_output, exec_sentinel):
6347 Use bool for booleans.
6348 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
6349 All callers changed.
6350 * eval.c (interactive_p): Omit always-true boolean argument
6351 EXCLUDE_SUBRS_P. All callers changed.
6352 * dispextern.h, lisp.h: Reflect above API changes.
6353 * firstfile.c (dummy): Use the address of 'main', whose signature
6354 won't change, instead of the address of 'initialize', whose
6355 signature just changed from int to bool.
6356 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
6357 * msdos.c (fatal_error_in_progress): ... from here.
6358 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6360 (redisplay_internal, unwind_redisplay): Simply clear
6361 REDISPLAYING_P when unwinding, instead of saving its previous,
6362 always-false value and then restoring it.
6364 Clean up some extern decls.
6365 Mostly, this hoists extern decls out of .c files and into .h files.
6366 That way, we're more likely to catch errors if the interfaces change.
6367 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6368 declare xg_mark_data.
6369 * dispextern.h (x_frame_parm_handlers):
6371 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
6372 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
6373 (Qultra_bold, Qoblique, Qitalic):
6374 Move extern decl here from .c file.
6375 * alloc.c (xg_mark_data) [USE_GTK]:
6377 * eval.c (Qlexical_binding):
6378 * fns.c (time) [!HAVE_UNISTD_H]:
6379 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
6380 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):

6582 * lread.c (init_lread): For out-of-tree builds, only add the
6583 source directory's site-lisp dir to the load-path if it exists,
6584 consistent with in-tree builds. (Bug#12302)
6586 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

6831 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6833 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6834 as that's faster and simpler than static storage. Don't bother
6835 with the g_main_context_query overhead if g_main_context_pending
6836 says no events are pending.
6837 (gfds, gfds_size): Remove these static vars.
6838 (xgselect_initialize): Remove; no longer needed.
6839 All uses and decls removed.
6841 * emacs.c (fatal_error_signal_hook): Remove.
6842 All uses removed. This leftover from old code was always 0.
6844 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
6845 * casefiddle.c (casify_object, casify_region):
6846 * casetab.c (set_case_table):
6847 * category.c, category.h (word_boundary_p):
6848 * category.h (CHAR_HAS_CATEGORY):
6849 Use bool for booleans, instead of int.
6851 2012-08-25 Eli Zaretskii <eliz@gnu.org>
6853 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6855 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6857 On assertion failure, print backtrace if available.
6858 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6859 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6860 * Makefile.in (LIB_EXECINFO): New macro.
6863 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6864 * bytecode.c (exec_byte_code):
6865 * callint.c (check_mark, Fcall_interactively):
6866 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6867 (getenv_internal, sync_process_alive, call_process_exited):
6868 * lisp.h (USE_SAFE_ALLOCA):
6869 Use bool for booleans, instead of int.
6870 * lisp.h, process.h: Adjust prototypes to match above changes.
6871 * callint.c (Fcall_interactively): Don't assume the mark's
6872 offset fits in 'int'.
6874 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6876 * buffer.c, buffer.h: Use bool for boolean.
6877 * buffer.c (reset_buffer_local_variables)
6878 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6879 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6880 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6881 (overlay_touches_p, overlay_strings, Foverlay_put)
6882 (report_overlay_modification, call_overlay_mod_hooks):
6883 (mmap_enlarge, mmap_set_vars):
6884 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6885 Use bool for booleans, instead of int.
6886 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6887 since the 1-or-0 return value is always ignored anyway.
6888 (mmap_initialized_p):
6889 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6890 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6892 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6894 * bidi.c: Use bool for boolean.
6895 This is a bit more readable, and makes the text segment of bidi.o
6896 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6897 Presumably it's faster too.
6898 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6900 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6901 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6902 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6903 (bidi_explicit_dir_char, bidi_level_of_next_char)
6904 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6905 Use bool for booleans, instead of int.
6906 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6907 (bidi_unshelve_cache): Adjust decls to match code.
6909 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6911 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6914 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6916 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6917 * atimer.h: Include <stdbool.h>.
6919 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6921 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6922 compile time tests instead of run time tests on systems that do
6924 (FRAME_MAC_P): Remove leftover from deleted code.
6925 * frame.c (syms_of_frame): Remove leftover from deleted code.
6927 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6929 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6931 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6933 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6934 Otherwise, the compiler complains about (A?B:C) where B is void
6935 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6936 (fontset_add): Return void, for FONTSET_ADD.
6938 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6940 * alloc.c: Use bool for booleans.
6941 (gc_in_progress, abort_on_gc)
6942 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6943 (dont_register_blocks) [GC_MALLOC_CHECK]:
6944 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6945 (check_string_bytes, make_specified_string, memory_full)
6946 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6947 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6948 (mark_stack, valid_pointer_p, make_pure_string)
6949 (Fgarbage_collect, survives_gc_p, gc_sweep):
6950 Use bool for booleans, instead of int.
6951 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6952 Remove unused local.
6953 * alloc.c (PURE_POINTER_P):
6954 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6955 * editfns.c (Fformat):
6956 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6958 * fns.c (sweep_weak_table):
6959 * lisp.h (suppress_checking, push_message, survives_gc_p)
6960 (make_pure_string, gc_in_progress, abort_on_gc):
6961 * lread.c (readchar, read1):
6962 * print.c (Fprin1_to_string):
6963 * xdisp.c (push_message):
6964 Use bool for booleans affected directly or indirectly by
6967 Make recently-introduced setters macros.
6968 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6969 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6970 (set_fontset_default, set_fontset_fallback): Rename from their
6971 upper-case counterparts, and make them functions rather than macros.
6972 This is more consistent with the other recently-introduced setters.
6973 These don't need to be inline, since they're local.
6975 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6977 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6978 the loop (Bug#12247).
6980 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6982 * lisp.h (vcopy): Use memcpy rather than our own loop.
6983 This fixes a performance regression introduced by the recent
6984 addition of vcopy. This means 'vcopy' will need to be modified
6985 for a copying collector, but that's OK. Also, tighten the
6986 checking in the assertion.
6988 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6990 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6991 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6992 non-base glyph for the width of the base character, according to
6993 what x_draw_composite_glyph_string_foreground expects.
6994 Generate WADJUST value according to composition_gstring_width's
6995 expectations, to produce correct width of the composed character.
6996 Reverse the sign of the DU offset produced by ScriptPlace.
6998 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7000 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7002 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7004 Avoid direct writes to contents member of struct Lisp_Vector.
7005 * lisp.h (vcopy): New function to copy data into vector.
7006 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7007 * fns.c (Ffillarray): Use ASET.
7008 * keyboard.c (timer_check_2): Use AREF and ASET.
7009 (append_tool_bar_item, Frecent_keys): Use vcopy.
7010 * lread.c (read_vector): Use ASET.
7011 * msdos.c (Frecent_doskeys): Use vcopy.
7012 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7013 (Finternal_merge_in_global_face): Use ASET and vcopy.

7019 the position of its buffer's point.
7020 (Fset_window_point): For the selected window always go in its
7021 buffer to the specified position.
7023 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7025 Setter macros for fontsets.
7026 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7027 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7028 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7031 2012-08-20 Glenn Morris <rgm@gnu.org>
7033 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7034 Don't assume that `ln -f' works.
7036 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7038 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
7039 and later about non-assignments with no effect. See discussion at
7040 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
7043 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7045 Inline setter functions for Lisp_Objects slots of struct specbinding.
7046 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
7049 2012-08-20 Martin Rudalics <rudalics@gmx.at>
7051 * window.c (select_window): Always make selected window's buffer
7054 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7056 Use AREF and ASET for docstrings of category tables.
7057 * category.h (CATEGORY_DOCSTRING): Use AREF.
7058 (SET_CATEGORY_DOCSTRING): Use ASET.
7059 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
7061 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7063 Inline setter functions for hash table members.
7064 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
7065 (set_hash_hash, set_hash_index): Rename with _slot suffix.
7066 (set_hash_key_and_value, set_hash_index, set_hash_next)
7067 (set_hash_hash): New functions.
7068 * charset.c, fns.c: Adjust users.
7070 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7072 Inline getter and setter functions for per-buffer values.
7073 * buffer.h (per_buffer_default, set_per_buffer_default)
7074 (per_buffer_value, set_per_buffer_value): New functions.
7075 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
7076 * buffer.c, data.c: Adjust users.
7078 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
7080 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
7082 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7084 Rely on <config.h> + <unistd.h> to declare 'environ',
7085 as gnulib does this if the system doesn't.
7086 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7087 Remove declaration. MS-Windows declares it on stdlib.h which is
7088 included by conf_post.h.
7089 * emacs.c (environ) [DOUG_LEA_MALLOC]:
7090 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
7091 * vm-limit.c: Include <unistd.h>, for 'environ'.
7093 * unexaix.c, unexcoff.c: Include "mem-limits.h".
7094 (start_of_data): Remove decl; mem-limits.h provides it.
7096 * xdisp.c (handle_invisible_prop): Make it a bit faster
7097 and avoid a gcc -Wmaybe-uninitialized diagnostic.
7099 2012-08-19 Chong Yidong <cyd@gnu.org>
7101 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
7104 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
7106 * .gdbinit: Use call instead of set when calling a function in the
7109 * data.c (set_internal): Don't use set_blv_found.
7110 (Fkill_local_variable): Likewise.
7112 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
7114 * nsfont.m (ns_ascii_average_width): Ensure the string
7115 ascii_printable is initialized with a null-terminated character
7116 array. Otherwise, it can contain undesired extra characters.
7118 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7120 port new setting code to Sun C 5.8 2005/10/13
7121 * chartab.c, lisp.h (char_table_set, char_table_set_range):
7122 Return void, not Lisp_Object. Otherwise, the compiler
7123 complains about (A?B:C) where B is void and C is Lisp_Object
7124 when compiling CHAR_TABLE_SET, due to the recent change to
7125 the API of sub_char_table_set_contents.
7127 2012-08-18 Chong Yidong <cyd@gnu.org>
7129 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
7130 for the string case (Bug#3874).
7132 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7134 * buffer.h (BSET): Remove (Bug#12215).

7213 are compiled into code.
7214 (tset_param_alist): New setter function.
7216 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>
7218 * keyboard.h (KSET): Remove (Bug#12215).

7957 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
7958 * w32.c (init_environment): Change the default values of many
7959 environment variables in dflt_envvars[] to NULL, to avoid pushing
7960 them into environment when they were not already defined.
7961 Remove the code that deletes site-lisp subdirectories from the default
7962 value of EMACSLOADPATH, as it is no longer needed.
7963 (check_windows_init_file): Now external, not static.
7964 Use Vload_path as is, without adding anything, as this function is now
7965 called when Vload_path is already set up.
7967 * w32.h (check_windows_init_file): Add prototype.
7969 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

8013 Remove unnecessary pointer casts.
8014 * alloc.c (record_xmalloc): New function.
8015 * lisp.h (record_xmalloc): New decl.
8016 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8017 more like a function. This is because the pointer cast is not
8018 needed. All uses changed.
8019 * print.c (print_string, print_error_message): Avoid length recalc.
8021 Improve fix for macroexp crash with debugging (Bug#12118).
8022 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
8023 ARRAY_MARK_FLAG when checking subscripts, because ASET is
8024 not supposed to be invoked from the garbage collector.

8026 (gc_aset): New function, which is like ASET but can be
8027 used in the garbage collector.

8056 with addition of handling of symlinks and support for 'lstat'.
8057 If possible, get file's attributes and security information by
8058 handle, not by name. Produce S_IFLNK bit for symlinks, when
8059 called from 'lstat'.
8060 (stat, lstat): New functions, call 'stat_worker'.
8061 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8062 symlinks when the underlying filesystem supports them.
8064 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
8066 Fix macroexp crash on Windows with debugging (Bug#12118).
8067 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8068 checking subscripts; problem introduced with the recent
8069 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8070 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8071 since it's used in non-static inline functions now.
8073 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
8074 Don't assume buffer size fits in 'int'. Remove unused local.

8095 * dispnew.c (DISPEXTERN_INLINE):
8096 * sysdep.c (SYSTIME_INLINE):
8097 Define to EXTERN_INLINE, so that the corresponding functions
8098 are compiled into code.
8099 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
8100 (INLINE_HEADER_END): New macros.
8101 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

8121 hard-coding the path separator.
8123 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
8125 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
8126 This how ASET and AREF are supposed to work, and makes
8127 it easier to think about future improvements. See
8128 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
8129 * charset.h (set_charset_attr): New function.

8598 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8600 Fast save_excursion_save and save_excursion_restore.
8601 * lisp.h (struct Lisp_Excursion): New data type.
8602 (PVEC_EXCURSION): New pseudovector type.
8603 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
8604 to deal with it. Adjust comments.
8605 (init_marker, attach_marker): New prototype.
8606 (unchain_marker): Adjust prototype.

8618 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
8619 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
8620 emacs.c, as this is a more-suitable home. Had this been done earlier
8621 the fix for 12036 would have avoided some of the problems noted in
8622 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8623 would have been more obvious.
8624 * emacs.c: Do not include <verify.h>; no longer needed.
8625 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
8626 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
8627 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8628 Remove; now done in lisp.h.
8629 * lisp.h (PUBLISH_TO_GDB): New macro.

8631 (DATA_SEG_BITS): Use it.
8632 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
8633 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8634 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8635 not be usable in #if. This simplifies things.
8637 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8639 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
8641 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

8644 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8645 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8646 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8647 Adjust to changes in lisp.h and emacs.c, by using
8648 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8649 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8650 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8651 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8652 instead of gdb_valbits.
8653 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8654 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8655 instead of gdb_array_mark_flag.
8656 (xboolvector): Get size from $->size, not $->header.size.
8657 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8658 (xreload, hook-run, hookpost-run): Remove.
8659 * emacs.c: Include <verify.h>.
8660 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8661 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8663 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8664 (gdb_USE_LSB_TAG): New enum constants.
8665 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8666 Also define these as enum constants, so they're visible to GDB.
8667 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8668 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8669 as constants, so they're visible to GDB.

8671 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
8672 Now enum constants, not macros, so they're visible to GDB.
8673 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8674 more convenient now. All uses changed.
8675 (VALMASK) [USE_LSB_TAG]: Also define in this case.
8676 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
8678 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

8685 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
8686 add argument, tune behavior, and adjust all callers.
8688 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8690 Use typedef for EMACS_INT, EMACS_UINT.
8691 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8692 than macros. This simplifies debugging in the usual case, since
8693 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8694 and it allows expressions involving EMACS_INT casts.
8695 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8697 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

8709 Adjust buffer text indirection counters at the end of Fkill_buffer.
8710 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8711 buffer is definitely dead. This should really fix an issue reported
8712 by Christoph Scholtes again. (Bug#12007).
8713 (init_buffer_once): Initialize indirection counters of
8714 buffer_defaults and buffer_local_symbols (for sanity and safety).
8716 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8718 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8719 and continuation glyphs on tooltip frames, leave them at zero.

8747 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8749 Swap buffer text indirection counters in Fbuffer_swap_text.
8750 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8751 This avoids crash reported by Christoph Scholtes at
8752 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8754 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8756 * nsmenu.m (Popdown_data): New struct.

8779 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8781 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8782 as it's limited by the amount of memory, not by INT_MAX.
8784 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8786 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8787 in special-event-map. See the discussion at

8937 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8939 * eval.c (Fdefvar): Don't check constants since we only set the var if
8940 it's not yet defined anyway (bug#11904).
8942 * lisp.h (last_undo_boundary): Declare new var.
8943 * keyboard.c (command_loop_1): Set it.
8944 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
8945 were auto-added by the command loop (bug#11774).

9494 Change to return ptrdiff_t.
9495 (xfont_list_pattern, xfont_match): Use length returned by
9496 xfont_decode_coding_xlfd.
9497 * xfns.c (x_default_font_parameter): Omit useless xstrdup.
9499 2012-07-11 Glenn Morris <rgm@gnu.org>

9502 Move DONT_REOPEN_PTY to configure.
9504 * sound.c (DEFAULT_SOUND_DEVICE) [!WINDOWSNT]:
9505 * s/netbsd.h (DEFAULT_SOUND_DEVICE): Let configure set it.
9507 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
9509 Remove "#define unix" that is no longer needed (Bug#11905).
9510 * s/aix4-2.h (unix): Remove; no longer needed.
9512 EMACS_TIME simplification (Bug#11875).
9513 This replaces macros (which typically do not work in GDB)
9514 with functions, typedefs and enums, making the code easier to debug.
9515 The functional style also makes code easier to read and maintain.
9516 * systime.h: Include <sys/time.h> on all hosts, not just if
9517 WINDOWSNT, since 'struct timeval' is needed in general.
9518 (EMACS_TIME): Now a typedef, not a macro.
9519 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
9521 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
9522 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
9523 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
9524 (EMACS_TIME_LE): Now functions, not macros.
9525 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
9526 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
9527 which are not functions. All uses rewritten to use:
9528 (make_emacs_time): New function.
9529 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
9530 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
9531 not functions. All uses rewritten to use the following, respectively:
9532 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
9533 (add_emacs_time, sub_emacs_time): New functions.
9534 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
9535 * fileio.c (Fcopy_file):
9536 * xterm.c (XTflash): Get the current time closer to when it's used.
9537 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

9543 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
9544 * frame.c (Fmake_terminal_frame):
9545 * gtkutil.c (get_utf8_string):
9547 * nsmenu.m (ns_update_menubar):
9548 * regex.c (regerror):
9549 Prefer memcpy to strncpy and strncat when either will do.
9550 * fileio.c (Fsubstitute_in_file_name):
9551 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
9552 (menu_separator_name_p):
9553 * nsmenu.m (ns_update_menubar):
9554 Prefer memcmp to strncmp when either will do.
9555 * nsterm.m: Include <ftoastr.h>.
9557 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9558 Prefer snprintf to strncpy.
9559 * nsterm.m (ns_term_init):
9560 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9561 * nsterm.m (ns_term_init):
9562 Avoid the need for strncpy, by using build_string or
9563 make_unibyte_string directly. Use dtoastr, not snprintf.
9564 * process.c (Fmake_network_process): Diagnose service names that
9565 are too long, rather than silently truncating them or creating
9566 non-null-terminated names.
9567 (Fnetwork_interface_info): Likewise, for interface names.
9568 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9569 Prefer sprintf to strncat.
9570 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
9571 Prefer vsnprintf to vsprintf + strncpy.
9573 2012-07-10 Glenn Morris <rgm@gnu.org>
9575 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
9576 Clarify fallback case.
9578 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9580 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
9581 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
9582 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
9583 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9584 where argument type is known to be a Lisp_Cons.
9586 2012-07-10 Tom Tromey <tromey@redhat.com>
9588 * bytecode.c (BYTE_CODE_THREADED): New macro.
9589 (BYTE_CODES): New macro. Replaces all old byte-code defines.
9590 (enum byte_code_op): New type.
9591 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.

9594 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9596 Optimize pure C strings initialization.
9597 * lisp.h (make_pure_string): Fix prototype.
9598 (build_pure_c_string): New function, defined as static inline. This
9599 provides a better opportunity to optimize away calls to strlen when
9600 the function is called with compile-time constant argument.
9601 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9602 argument, adjust users accordingly. Use build_pure_c_string where
9604 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9605 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9606 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9608 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9610 Avoid calls to strlen in miscellaneous functions.
9611 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
9612 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
9613 * lread.c (openp): Likewise.
9615 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9617 Avoid calls to strlen in path processing functions.
9618 * fileio.c (file_name_as_directory): Add comment. Change to add
9619 srclen argument and return the length of result. Adjust users
9621 (directory_file_name): Fix comment. Change to add srclen argument,
9622 swap 1st and 2nd arguments to obey the common convention.
9623 Adjust users accordingly.
9624 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
9626 2012-07-10 Glenn Morris <rgm@gnu.org>
9628 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
9629 Move PENDING_OUTPUT_COUNT definition to configure.
9631 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
9632 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
9633 * s/gnu.h (DATA_START): Move definitions to configure.
9635 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9636 We include usg5-4-common.h, which defines them both.
9638 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9639 O_RDONLY already includes it).
9641 Stop ns builds setting the EMACSLOADPATH environment variable.
9642 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9643 Now it does not set EMACSLOADPATH, just returns the load-path string.
9644 * nsterm.h: Update accordingly.
9645 * lread.c [HAVE_NS]: Include nsterm.h.
9646 (init_lread) [HAVE_NS]: Use ns_load_path.
9647 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
9649 2012-07-09 Glenn Morris <rgm@gnu.org>
9651 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9652 since the included bsd-common.h does so.
9654 Stop ns builds setting the EMACSPATH environment variable.
9655 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9656 (ns_init_paths): Do not set EMACSPATH.
9657 * nsterm.h (ns_exec_path): Add it.
9658 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9661 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9663 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9665 * process.c (wait_reading_process_output): 'waitchannels' was unset
9666 when read_kbd || !NILP (wait_for_cell); fix this.
9668 Add GCC-style 'const' attribute to functions that can use it.
9669 * character.h (char_resolve_modifier_mask):
9670 * keyboard.h (make_ctrl_char):
9671 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
9672 (init_character_once, next_almost_prime, init_fns, init_image)
9673 (flush_pending_output, init_sound):
9674 * mem-limits.h (start_of_data):
9675 * menu.h (finish_menu_items):
9676 Add ATTRIBUTE_CONST.

9678 Declare the dummy function with ATTRIBUTE_CONST.
9679 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
9680 Add decls with ATTRIBUTE_CONST.
9682 Minor improvements to make_formatted_string.
9683 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9684 where int is good enough, as vsprintf returns an int.
9685 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9687 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9689 Use make_formatted_string to avoid double length calculation.
9690 * lisp.h (make_formatted_string): New prototype.
9691 * alloc.c (make_formatted_string): New function.
9692 * buffer.c (Fgenerate_new_buffer_name): Use it.
9693 * dbusbind.c (syms_of_dbusbind): Likewise.

9695 * filelock.c (get_boot_time): Likewise.
9696 * frame.c (make_terminal_frame, set_term_frame_name)
9697 (x_report_frame_params): Likewise.
9698 * image.c (gs_load): Likewise.
9699 * minibuf.c (get_minibuffer): Likewise.
9700 * msdos.c (dos_set_window_size): Likewise.
9701 * process.c (make_process): Likewise.

9714 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9716 Move marker debugging code under MARKER_DEBUG.
9717 * marker.c (MARKER_DEBUG): Move marker debugging code under
9718 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9719 for bootstrap with --enable-checking (~3x slowdown reported
9720 by Juanma Barranquero <lekktu@gmail.com>).
9721 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9723 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9725 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9726 See <http://bugs.gnu.org/11825#29>.
9728 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9730 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9731 has no font, use the frame's font. (Bug#11813)
9732 (display_line): Add commentary about displaying truncation glyphs
9734 (produce_special_glyphs): Move here from term.c.
9736 * term.c (produce_special_glyphs): Move to xdisp.c.
9738 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9741 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9743 * xdisp.c (display_line): Avoid warning about implicit declaration
9746 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9748 * lisp.h: Remove empty conditional.
9750 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9752 * lread.c (load_path_check): Now static.
9754 Fix some minor --with-ns problems found by static checking.
9755 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9756 (x_set_font) [!HAVE_X_WINDOWS]:
9757 * image.c (xpm_load_image) [HAVE_NS]:
9758 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9759 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9760 Remove unused local.
9761 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9762 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9763 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9764 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9765 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9766 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9767 Fix pointer signedness problem.
9768 * xfaces.c (FRAME_X_FONT_TABLE):
9769 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9771 2012-07-07 Glenn Morris <rgm@gnu.org>
9773 * lread.c (load_path_check): New function, split from init_lread.
9774 (init_lread): Reorganize. Motivation:
9775 If EMACSLOADPATH is set, check/warn about that rather than the
9776 defaults, which we are not going to use. Hence we can remove
9777 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9778 Don't warn if site-lisp directories are missing.
9779 If not installed, start from a blank load-path, since
9780 PATH_LOADSEARCH refers to the eventual installation directories.
9782 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9784 Support truncation and continuation glyphs on GUI frames, when
9785 fringes are disabled. (Bug#11832)
9786 * xdisp.c (init_iterator): Get dimensions of truncation and
9787 continuation glyphs even if on GUI frames.
9788 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9789 or both, are absent.
9790 (start_display, move_it_in_display_line_to): Handle the case of a
9791 GUI frame without a fringe to display continuation or truncation
9793 (insert_left_trunc_glyphs): Support GUI frames: make sure
9794 truncation glyphs overwrite enough glyphs from the current line to
9795 have sufficient space in pixels.
9796 (display_line): Support truncation and continuation glyphs on GUI
9797 frames. If some spare pixels are left on the line after inserting
9798 the truncation glyphs, fill that space with a stretch glyph of a
9799 suitably computed width.
9801 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9802 produce_glyphs, to support GUI sessions.
9804 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9806 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9808 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9810 Do not require float-time's arg to fit in time_t (Bug#11825).
9811 This works better on hosts where time_t is unsigned, and where
9812 float-time is applied to the (negative) difference between two times.
9813 * editfns.c (decode_time_components): Last arg is now double *,
9814 not int *, and means to store all the result as a double, without
9815 worrying about whether the seconds part fits in time_t.
9816 All callers changed.
9817 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9818 All callers changed.
9819 (Ffloat_time): Do not fail merely because the specified time falls
9820 outside of time_t range.
9822 2012-07-07 Glenn Morris <rgm@gnu.org>
9824 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
9825 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
9826 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
9828 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
9830 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
9831 Update dependencies.
9833 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
9835 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9837 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
9838 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
9839 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9840 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9841 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
9842 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
9844 * xfont.c (compare_font_names): Redo to omit the need for casts.
9846 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9848 * xfns.c (Fx_change_window_property): Doc fix.
9849 * w32fns.c (Fx_change_window_property): Doc fix.
9851 * w32fns.c (Fx_window_property): Accept the same arguments as the
9852 X Windows version. Doc fix.
9853 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9855 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9856 Eli Zaretskii <eliz@gnu.org>
9858 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9859 Windows-specific code from nt/config.nt moved here.
9860 Obsolete settings removed.
9862 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9864 * process.c: Avoid unnecessary calls to gettime.
9865 (wait_reading_process_output): Don't get the time of day
9866 when gobbling data immediately and not waiting, as there's no need
9867 for it in that case. This removes a FIXME.
9869 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9871 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9872 is defined (Bug#11768).
9874 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9876 Fix marker debugging code.
9877 * marker.c (byte_char_debug_check): Do not perform the check
9878 if buffer is not multibyte.
9879 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9880 Call byte_char_debug_check with correct arguments.
9882 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9884 Compile marker debugging code only if ENABLE_CHECKING is defined.
9885 * marker.c (byte_char_debug_check, count_markers):
9886 Use only if ENABLE_CHECKING is defined.
9887 (byte_debug_flag): Remove.
9888 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9889 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9891 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9893 Avoid code repetition in marker-related functions.
9894 * marker.c (attach_marker): New function.
9895 (Fset_marker, set_marker_restricted, set_marker_both)
9896 (set_marker_restricted_both): Use it.
9897 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9898 Consistently rename charno to charpos.
9899 (marker_position): Add eassert.
9900 (marker_byte_position): Convert to eassert.

9919 * window.c (save_window_save): Likewise.
9921 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9923 Do not use Fdelete_overlay in delete_all_overlays
9924 to avoid redundant calls to unchain_overlay.
9925 * buffer.c (drop_overlay): New function.
9926 (delete_all_overlays, Fdelete_overlay): Use it.
9927 * minibuf.c (get_minibuffer): Fix comment.
9929 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9931 Port to OpenBSD 5.1 amd64.
9932 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9933 This is needed for OpenBSD, and should be harmless on all BSD systems.
9934 Also, include <sys/sysctl.h>, as it should be available on all
9935 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9936 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9937 use p_pid member, not kp_proc.pid.
9939 2012-07-06 Glenn Morris <rgm@gnu.org>
9941 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9943 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9945 More xmalloc and related cleanup.

9954 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9956 Omit needless casts involving void * pointers and allocation.
9957 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9958 as the former is more robust if P's type is changed.
9959 Prefer xzalloc to xmalloc + memset 0.
9960 Simplify malloc-or-realloc to realloc.
9961 Don't worry about xmalloc returning a null pointer.
9962 Prefer xstrdup to xmalloc + strcpy.
9963 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9965 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9966 alloca of a constant.
9968 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9970 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9971 hscroll is larger than the line width. Fixes long and futile
9972 looping inside extend_face_to_end_of_line (on a TTY) producing
9973 glyphs that are not needed and thrown away.
9975 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9977 * marker.c (set_marker_restricted_both): Simplify by using
9980 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9982 * editfns.c (region_limit): Simplify by using clip_to_bounds.
9984 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
9986 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
9987 not defined (Bug#11768).
9988 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
9989 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
9990 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
9991 followed by gtk_box_set_homogeneous (Bug#11768).
9992 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9993 (update_theme_scrollbar_width, xg_create_scroll_bar):
9994 Use gtk_scrollbar_new (Bug#11768).
9995 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
9996 (is_box_type): New function (Bug#11768).
9997 (xg_tool_item_stale_p): Call is_box_type.
9998 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
9999 with default display (Bug#11768).
10001 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10003 * xdisp.c (window_hscroll_limited): New function.
10004 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10005 coordinates when window's hscroll is set to insanely large
10006 values. (Bug#11857)
10008 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
10010 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

10071 * fileio.c (time_error_value): Check the right error number.
10072 Problem reported by Troels Nielsen in
10073 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10075 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10077 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10078 This should be fixed in a better way; see Eli Zaretskii in
10079 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10080 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10082 * fileio.c (time_error_value): Rename from special_mtime.
10083 The old name's problems were noted by Eli Zaretskii in
10084 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10086 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10087 This variable's comment says Emacs needs at least one GDB-visible
10088 symbol of type enum pvec_type, to work around GDB problems.
10089 The symbol's value doesn't matter.
10091 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10092 that causes compilation to fail on pre-C99 compilers.
10094 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10096 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
10097 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
10099 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10101 * buffer.c (init_buffer_once): Fix initialization of
10102 headers for buffer_defaults and buffer_local_symbols.
10103 Reported by Juanma Barranquero <lekktu@gmail.com>.
10105 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
10107 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
10108 * lisp.h (enum pvec_type): Use fewer bits.
10109 (PSEUDOVECTOR_SIZE_BITS): New constant.
10110 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
10111 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
10112 change in pvec_type.
10113 (PSEUDOVECTOR_TYPEP): New macro.
10114 (TYPED_PSEUDOVECTORP): Use it.
10115 * fns.c (internal_equal): Adapt code to extract pvectype.
10116 * emacs.c (gdb_pvec_type): Update type.
10117 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
10118 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
10119 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
10120 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10121 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10122 abusing vector->header.next.nbytes.
10123 (live_vector_p): Use PVEC_TYPE.
10124 (mark_object): Adapt code to extract pvectype. Use switch.
10126 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10128 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10129 Tighten new eassert a bit.
10131 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10133 Fix compilation with --enable-gcc-warnings and -O1
10134 optimization level.
10135 * doprnt.c (doprnt): Change type of tem to int, initialize
10136 to avoid compiler warning. Add eassert.
10137 * search.c (simple_search): Initialize match_byte to avoid
10138 compiler warning. Add eassert.
10140 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10142 Avoid weird behavior with large horizontal scrolls.
10143 Without this change, for example, large hscroll values would
10144 mess up Emacs's display on Fedora 15 x86, presumably due to
10145 overflows in int calculations in the display code.
10146 Also, if buffers had long lines, Emacs would freeze.
10147 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10148 (set_window_hscroll): New function, containing the old guts of
10149 Fset_window_hscroll. Return the clipped value.
10150 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10151 This avoids the need to check against PTRDIFF_MAX.
10153 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10155 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10157 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10159 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10161 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10162 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10163 since GCC 4.4.6 issues a bogus warning for them.
10165 Fix bugs in file timestamp newness comparisons.
10166 * fileio.c (Ffile_newer_than_file_p):
10167 * lread.c (Fload): Use full timestamp resolution of files,
10168 not just the 1-second resolution, so that files that are only
10169 slightly newer still count as newer.
10170 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10171 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10173 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10175 * fileio.c: Improve handling of file time marker. (Bug#11852)
10176 (special_mtime): New function.
10177 (Finsert_file_contents, Fverify_visited_file_modtime):
10178 Use it to set special mtime values consistently.
10180 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10182 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10183 marker for non-existing file. (Bug#11852)
10185 2012-07-03 Glenn Morris <rgm@gnu.org>
10187 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10188 and did not make it into globals.h).
10190 2012-07-03 Tom Tromey <tromey@redhat.com>
10192 * window.c (Fset_window_margins, Fset_window_fringes)
10193 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
10194 * textprop.c (Fprevious_property_change): No longer static.
10195 * syntax.c (Fsyntax_table_p): No longer static.
10196 * process.c (Fget_process, Fprocess_datagram_address): No longer

10215 * buffer.h: Remove EXFUNs.
10216 * dispextern.h: Remove EXFUNs.
10217 * intervals.h: Remove EXFUNs.
10218 * fontset.h: Remove EXFUN.
10219 * font.h: Remove EXFUNs.
10220 * dosfns.c (system_process_attributes): Remove EXFUN.
10221 * keymap.h: Remove EXFUNs.
10222 * lisp.h: Remove EXFUNs.
10223 * w32term.h: Remove EXFUNs.
10224 * window.h: Remove EXFUNs.
10225 * xsettings.h: Remove EXFUN.
10226 * xterm.h: Remove EXFUN.
10228 2012-07-03 Glenn Morris <rgm@gnu.org>
10230 * lisp.h (Frandom): Make it visible to C.
10231 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
10232 buffer for invisible buffers. (Bug#1229)
10234 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10236 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
10237 values which aren't power of 2.
10238 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10239 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
10242 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
10244 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
10246 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10248 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10250 * alloc.c (allocate_vector_block): Remove redundant
10251 calls to mallopt if DOUG_LEA_MALLOC is defined.
10252 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10253 avoid calls to mallopt if zero_vector is returned.
10255 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10257 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10258 is enabled, avoid dereferencing NULL current_sblock if
10261 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10263 Cleanup basic buffer management.
10264 * buffer.h (struct buffer): Change layout to use generic vector
10265 marking code. Fix some comments. Change type of 'clip_changed'
10266 to bitfield. Remove unused #ifndef old.
10267 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10268 (GET_OVERLAYS_AT): Fix indentation.
10269 (for_each_per_buffer_object_at): New macro.
10270 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
10271 (Fbuffer_local_variables): Use it.
10272 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.

10274 struct buffer. Fix comment.
10275 (mark_overlay): New function.
10276 (mark_buffer): Use it. Use mark_vectorlike to mark normal
10277 Lisp area of struct buffer.
10278 (mark_object): Use it. Adjust marking of misc objects
10279 and related comments.
10281 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10283 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10284 wrapper that is not needed because the wrapped code is a no-op (zero
10285 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10286 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10288 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10290 * alloc.c (mark_buffer): Simplify. Remove prototype.
10291 (mark_object): Add comment. Reorganize marking of vector-like
10292 objects. Use CHECK_LIVE for all vector-like objects except buffers
10293 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10294 Avoid redundant calls to mark_vectorlike for bool vectors.
10296 2012-06-30 Glenn Morris <rgm@gnu.org>
10298 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10300 * epaths.in (PATH_SITELOADSEARCH): New.
10301 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10302 This is rather than relying on --enable-locallisppath elements
10303 having "site-lisp" in their names. (Bug#10208#25, 11658)
10305 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10307 * w32proc.c (sys_select): Accept and ignore one more argument.
10309 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10311 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10312 (pselect) [!MS_DOS]: Redirect to sys_select.
10314 * sysdep.c: Don't include dos.h and dosfns.h.
10316 * process.c (sys_select):
10317 * msdos.c (sys_select): Accept one more argument and ignore it.
10319 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10320 adapt data types and code to that.
10323 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10324 which clashes with the gnulib function of the same name.
10326 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10328 * font.c (font_style_to_value, font_style_symbolic)
10329 (font_prop_validate_style): Add type checks for values in
10332 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10334 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10337 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10339 * xdisp.c (try_window_id): Undo last change.
10341 * w32.c (getwd): Adjust commentary about startup_dir.
10342 (init_environment): Always call sys_access, even in non-MSVC
10343 builds. Don't chdir to the directory of the Emacs executable.
10344 This undoes code from 1997 which was justified by the need to
10345 "avoid conflicts when removing and renaming directories". But its
10346 downside was that every relative file name was being interpreted
10347 relative to the directory of the Emacs executable, which can never
10348 be TRT. In particular, it broke sys_access when called with
10349 relative file names.
10350 (sys_access): Map GetLastError to errno.
10352 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10354 * window.h (struct window): Change type of 'fringes_outside_margins'
10355 to bitfield. Fix comment. Adjust users accordingly.
10356 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
10358 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10361 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
10363 * gnutls.c (emacs_gnutls_handshake):
10364 Add QUIT to make the loop interruptible.
10366 2012-06-29 Glenn Morris <rgm@gnu.org>
10368 * charset.c (init_charset): Make lack of etc/charsets fatal.
10370 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10372 * editfns.c (region_limit): Fix type mismatch.
10374 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10376 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
10377 undefined. Convert from xassert to eassert.
10378 * nsmenu.m: Convert from xassert to eassert.
10379 * nsterm.m: Likewise.
10381 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
10383 * editfns.c (region_limit): Clip to narrowing (bug#11770).
10385 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
10387 Avoid integer overflow on scroll-left and scroll-right.

10544 Use sprintf return value instead of invoking strlen on result.
10545 In the old days this wasn't portable, since some sprintf
10546 implementations returned char *. But they died out years ago and
10547 Emacs already assumes sprintf returns int.
10548 Similarly for float_to_string.
10549 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

10557 Use sprintf or float_to_string result to avoid need to call strlen.
10558 * data.c (Fnumber_to_string):
10559 Use make_unibyte_string, since the string must be ASCII.
10560 * lisp.h, print.c (float_to_string): Now returns int length.
10561 * term.c (produce_glyphless_glyph):
10562 Use sprintf result rather than recomputing it.
10564 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

10593 * xfns.c (x_window): Remove redundant cast.
10595 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10597 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10598 `const char *' to `char *' to avoid compiler warning.
10600 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10602 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10603 instead of truncating it to 63 (admittedly a generous limit).
10605 * process.c: Fix spelling and caps in comments.

10658 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10660 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

10663 * keyboard.c (kbd_buffer_get_event):
10664 * process.c (Faccept_process_output):
10665 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10666 This improves on the previous patch, which introduced a bug
10667 when time_t is unsigned and as wide as intmax_t.
10668 See <http://bugs.gnu.org/9000#51>.
10670 2012-06-23 Eli Zaretskii <eliz@gnu.org>

10699 language ID in the event parameters.
10701 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10702 event.code, not the obscure "character set ID".

10733 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10735 Support higher-resolution time stamps (Bug#9000).
10736 The time stamps are only nanosecond-resolution at the C level,
10737 since that's the best that any real-world system supports now.
10738 But they are picosecond-resolution at the Lisp level, as that's
10739 easy, and leaves room for future OS improvements.
10741 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10744 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10745 Don't get current time unless it's needed.
10747 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10748 now provides it if it's absent.
10749 (start_atimer): Port to higher-res time stamps.
10750 Check for time stamp overflow. Don't get current time more
10751 often than is needed.
10753 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10754 Include systime.h, not time.h.
10755 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10757 * dired.c: Include stat-time.h.
10758 (Ffile-attributes): File times now have higher resolution.
10760 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10761 (struct image): Timestamp now has higher resolution.
10763 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10764 has at least microseconds now. All uses removed.
10765 (update_frame, update_single_window, update_window, update_frame_1)
10766 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10767 (duration_to_sec_usec): Remove; no longer needed.
10769 * editfns.c (time_overflow): Now extern.
10770 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10771 (float-time, Fformat_time_string, Fcurrent_time_string)

10774 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
10775 (decode_time_components, lisp_seconds_argument): New functions.
10776 (make_time): Now static.
10777 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10778 Report an error if the time is invalid, rather than having the caller
10781 * fileio.c: Include <stat-time.h>
10782 (Fcopy_file): Copy higher-resolution time stamps.
10783 Prefer to set the time stamp via a file descriptor if that works.
10784 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10785 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10786 (Fvisited_file_modtime, Fset_visited_file_modtime):
10787 Support higher-resolution time stamps.
10789 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10791 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10793 * image.c (prepare_image_for_display, clear_image_cache)
10794 (lookup_image): Port to higer-resolution time stamps.
10796 * keyboard.c (start_polling, bind_polling_period):
10797 Check for time stamp overflow.
10798 (read_char, kbd_buffer_get_event, timer_start_idle)
10799 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10800 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10801 Port to higher-resolution time stamps. Do not assume time_t is signed.
10802 (decode_timer): New function. Timers are now vectors of length 9,
10803 not 8, to accommodate the picosecond component.
10804 (timer_check_2): Use it.
10806 * nsterm.m (select_timeout, timeval_subtract): Remove.
10807 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10808 as they're a bit more accurate and handle overflow better.
10809 (ns_select): Change prototype to be compatible with pselect.
10810 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10811 * nsterm.h (ns_select): Adjust prototype.
10813 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10814 us-resolution time stamps.
10815 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10817 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10819 * lisp.h (time_overflow): New decl.
10820 (wait_reading_process_output): First arg is now intmax_t, not int,
10821 to accommodate larger waits.
10823 * process.h (struct Lisp_Process.read_output_delay):
10824 Now counts nanoseconds, not microseconds.
10825 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10827 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10828 (wait_reading_process_output):
10829 Port to ns-resolution time stamps.
10830 (Faccept_process_output, wait_reading_process_output):
10831 Check for time stamp overflow. Do not assume time_t is signed.
10832 (select_wrapper): Remove; we now use pselect.
10833 (Fprocess_attributes): Now generates ns-resolution time stamps.
10835 * sysdep.c: Include utimens.h. Don't include utime.h
10836 or worry about struct utimbuf; gnulib does that for us now.
10837 (gettimeofday): Remove; gnulib provides a substitute.
10838 (make_timeval): New function.
10839 (set_file_times): Now sets ns-resolution time stamps.
10840 New arg FD; all uses changed.
10841 (time_from_jiffies, ltime_from_jiffies, get_up_time)
10842 (system_process_attributes):
10843 Now returns ns-resolution time stamp. All uses changed.
10844 Check for time stamp overflow.
10846 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10847 provides a substitute now.
10849 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10850 since it guarantees struct timespec.
10851 (EMACS_TIME): Now struct timespec, so that we can support
10852 ns-resolution time stamps.
10853 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10854 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10855 (EMACS_USECS): Remove.
10856 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10857 so multiply the arg by 1000 before storing it.

10860 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

10867 (make_timeval, make_lisp_time, decode_time_components): New decls.
10868 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10869 that it mishandled time_t overflow. You can't compare by subtracting!
10870 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10871 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10873 * term.c: Include <sys/time.h>.

10899 (timeval_subtract): Remove; no longer needed.
10900 (XTflash, XTring_bell, x_wait_for_event):

10910 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10911 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10912 staticidx goes up to 1597 out of 1600 = 0x640.)
10914 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10916 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.

10943 (prepare_menu_bars): Likewise.
10945 * term.c (Ftty_top_frame): New function.
10947 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10949 Port byte-code-meter to modern targets.
10950 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10951 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10952 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10953 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

10962 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10963 gets killed during executing of this function (Bug#11665).
10964 Try to always return Qt when the buffer has been actually killed.
10965 (Vkill_buffer_query_functions): In doc-string say that functions
10966 run by this hook should not change the current buffer.
10968 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10970 Fix recently-introduced process.c problems found by static checking.

10990 * lisp.h (eassert): Assume C89 or later.
10991 This removes the need for CHECK.
10992 (CHECK): Remove. Its comments about always evaluating its
10993 argument were confusing, as 'eassert' typically does not evaluate
10996 * coding.c (produce_chars): Use ptrdiff_t, not int.

11295 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
11297 2012-06-08 Eli Zaretskii <eliz@gnu.org>
11299 * alloc.c (allocate_vectorlike): Fix last change.
11301 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
11303 Block-based vector allocation of small vectors.
11304 * lisp.h (struct vectorlike_header): New field `nbytes',
11305 adjust comment accordingly.
11306 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
11307 to denote vector blocks. Adjust users (live_vector_p,
11308 mark_maybe_pointer, valid_lisp_object_p) accordingly.
11309 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
11310 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
11311 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
11312 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),
11313 (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.
11314 (roundup_size): New constant.
11315 (struct vector_block): New data type.
11316 (vector_blocks, vector_free_lists, zero_vector): New variables.

11319 (sweep_vectors): New functions.
11320 (allocate_vectorlike): Return `zero_vector' as the only vector of
11321 0 items. Allocate new vector from block if vector size is less than
11322 or equal to VBLOCK_BYTES_MAX.
11323 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
11324 (init_alloc_once): Add call to init_vectors.
11326 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
11328 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
11330 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
11332 * doprnt.c (doprnt): Truncate multibyte char correctly.
11333 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
11334 would mishandle a string argument "Xc" if X was a multibyte
11335 character of length 2: it would truncate after X's first byte
11336 rather than including all of X.
11338 2012-06-06 Chong Yidong <cyd@gnu.org>
11340 * buffer.c (word_wrap): Doc fix.
11342 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

11354 binary via PaX flags if the paxctl utility is available.
11355 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
11356 Restore PaX flags to their default. (Bug#11398)
11358 2012-06-03 Chong Yidong <cyd@gnu.org>
11360 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
11361 buffer (Bug#11226).

11365 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
11366 (note_mode_line_or_margin_highlight): If there is no help echo,
11367 use mode-line-default-help-echo. Handle the case where the mouse
11368 position is past the end of the mode line string.
11370 * buffer.c (buffer_local_value_1): New function, split from
11371 Fbuffer_local_value; can return Qunbound.
11372 (Fbuffer_local_value): Use it.
11373 (Vmode_line_format): Docstring tweaks.
11375 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>

11379 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
11381 * keyboard.c: Export real-this-command to Elisp.
11382 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
11383 and DEFVAR it. Update all users.
11385 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
11387 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11389 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11390 Convert pctcpu and pctmem to Lisp float properly.
11391 Let the compiler fold better, as 100.0/0x8000 is exact.
11393 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11395 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
11398 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
11400 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
11402 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
11404 For a 'struct window', replace some Lisp_Object fields to
11405 bitfields where appropriate, remove unused fields.
11406 * window.h (struct window): Remove unused 'last_mark_x' and
11407 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11408 change its type from Lisp_Object to bitfield.
11409 Change type of 'force_start', 'optional_new_start',
11410 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
11411 fields from Lisp_Object to bitfield. Adjust users accordingly.
11413 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11415 Pacify gcc -Wdouble-precision when using Xaw.
11416 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11417 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11418 Use 'float' consistently, rather than 'float' in most places
11419 and 'double' in a couple of places.
11421 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11423 * xdisp.c (handle_stop): Detect whether we have overlay strings
11424 loaded by testing it->current.overlay_string_index to be
11425 non-negative, instead of checking whether n_overlay_strings is
11426 positive. (Bug#11587)
11428 2012-05-31 Chong Yidong <cyd@gnu.org>
11430 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
11432 * doc.c (Fsubstitute_command_keys): Doc fix.
11434 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11436 * search.c (search_buffer): Remove calls to
11437 r_alloc_inhibit_buffer_relocation, as it is now called by
11438 maybe_unify_char, which was the cause of relocation of buffer text
11441 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11443 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11444 for the duration of call to load_charset, to avoid problems with
11445 callers of maybe_unify_char that access buffer text through C
11448 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11449 decrement the inhibition flag, instead of just setting or
11452 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11454 Remove obsolete '#define static' cruft.
11455 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11456 This #undef was "temporary" in 2000; it is no longer needed
11457 now that '#define static' has gone away.
11458 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11459 (gray_bitmap_bits): Remove; no longer needed.
11460 All uses replaced with definiens.
11461 * xterm.c: Include "bitmaps/gray.xbm".
11463 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
11465 Clean up __executable_start, monstartup when --enable-profiling.
11466 The following changes affect the code only when profiling.
11467 * dispnew.c (__executable_start): Rename from safe_bcopy.
11468 Define only on platforms that need it.
11469 * emacs.c: Include <sys/gmon.h> when profiling.
11470 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
11471 (__executable_start): Remove decl, since lisp.h does it now.
11472 (safe_bcopy): Remove decl; no longer has that name.
11473 (main): Coalesce #if into single bit of code, for simplicity.
11474 Cast pointers to uintptr_t, since standard libraries want integers
11476 * lisp.h (__executable_start): New decl.
11478 2012-05-31 Glenn Morris <rgm@gnu.org>
11480 * image.c (Fimagemagick_types): Doc fix.

11499 * lread.c (read1): Tiny simplification.
11501 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
11503 Do not create empty overlays with the evaporate property (Bug#9642).
11504 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11505 Bug#9642, but explicitly check that the buffer the overlay would
11506 be moved to is live and rearrange lines to make sure that errors
11507 will not put the overlay in an inconsistent state.
11508 (Fdelete_overlay): Cosmetics.
11510 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11512 * w32term.c (my_bring_window_to_top): New function.
11513 (x_raise_frame): Use handle returned by DeferWindowPos, which
11514 could be different from the original one.
11515 Call my_bring_window_to_top instead of my_set_foreground_window.

11524 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11526 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11527 This avoids undefined behavior that might cause the eassert
11528 to not catch an out-of-range value.
11530 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11532 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
11533 Update dependencies.

11537 * bidi.c (bidi_mirror_char): Fix last change.
11539 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

11544 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11546 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11547 Only r_alloc_inhibit_buffer_relocation needed to be added;
11548 the others were already declared.
11550 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11551 before checking whether it's out of range. Put the check inside
11553 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11555 2012-05-27 Ken Brown <kbrown@cornell.edu>
11557 * callproc.c (Fcall_process): Restore a line that was accidentally
11558 commented out in the 2011-02-13 change (bug#11547).
11560 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11562 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11563 defined on ralloc.c.
11565 * buffer.c [REL_ALLOC]: Remove prototypes of
11566 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11567 they are now on lisp.h.
11569 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11571 * search.c (search_buffer): Use it to inhibit relocation of buffer
11572 text while re_search_2 is doing its job, because re_search_2 is
11573 passed C pointers to buffer text. (Bug#11519)
11575 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11576 Update value to 24.
11578 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11579 state after an additional call to move_it_in_display_line_to, keep
11580 the values of it->max_ascent and it->max_descent found for the
11582 (pos_visible_p): Revert the comparison against bottom_y to what it
11583 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11586 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11588 Fix coding-related core dumps with gcc -ftrapv.
11589 The code was computing A - B, where A and B are pointers, and B is
11590 random garbage. This can lead to core dumps on platforms that
11591 have special pointer registers, and it also leads to core dumps on
11592 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11593 A - B only when B is initialized properly.
11594 * coding.c (coding_set_source, coding_set_destination): Return void.
11595 (coding_change_source, coding_change_destinations): New functions,
11596 with the old behaviors of coding_set_source and coding_set_destination.
11597 All callers that need an offset changed to use these new functions.
11599 2012-05-26 Glenn Morris <rgm@gnu.org>
11601 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
11603 2012-05-26 Eli Zaretskii <eliz@gnu.org>

11606 * xdisp.c (draw_row_with_mouse_face):
11607 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11609 * w32console.c: Include window.h.
11610 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11612 (initialize_w32_display): Initialize mouse-highlight data.
11614 * w32inevt.c: Include termchar.h and window.h.
11615 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11616 moves, call note_mouse_highlight. If help_echo changed, call
11617 gen_help_event to produce help-echo message in the echo area.
11618 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11621 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11623 * lread.c (read1): Simplify slightly to avoid an overflow warning
11624 with GCC 4.7.0 on x86-64.
11626 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11628 * bidi.c (bidi_mirror_char): Revert last change: an int is
11629 definitely wide enough here.
11631 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
11633 Fix integer width and related bugs (Bug#9874).

11641 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11643 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11645 Use int, not EMACS_INT, where int is wide enough.
11646 (inhibit_garbage_collection, Fgarbage_collect):
11647 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11648 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11649 int might not be wide enough.
11650 (bidi_cache_search, bidi_cache_find, bidi_init_it)
11651 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
11652 (bidi_at_paragraph_end, bidi_find_paragraph_start)
11653 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11654 (bidi_level_of_next_char, bidi_move_to_visually_next):
11655 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11656 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
11657 (Fkill_buffer, Fset_buffer_major_mode)
11658 (advance_to_char_boundary, Fbuffer_swap_text)

11660 (overlay_touches_p, struct sortvec, record_overlay_string)
11661 (overlay_strings, recenter_overlay_lists)
11662 (adjust_overlays_for_insert, adjust_overlays_for_delete)
11663 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)

11667 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11668 (validate_region): Omit unnecessary test for b <= e,
11669 since that's guaranteed by the previous test.
11670 (adjust_overlays_for_delete): Avoid pos + length overflow.
11671 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11672 (report_overlay_modification):
11673 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11674 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11675 Omit pointer cast, which isn't needed anyway, and doesn't work
11676 after the EMACS_INT -> ptrdiff_t change.
11677 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11678 * buffer.h: Adjust decls to match defn changes elsewhere.
11679 (struct buffer_text, struct buffer):
11680 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11681 Use EMACS_INT, not int, where int might not be wide enough.
11682 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11683 not int, to avoid needless 32-bit limit on 64-bit hosts.
11684 (exec_byte_code): Use tighter memory-full test, one that checks
11685 for alloca overflow. Don't compute the address of the object just
11686 before an array, as that's not portable. Use EMACS_INT, not
11687 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11688 * callint.c (Fcall_interactively):
11689 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11690 * callproc.c (call_process_kill, Fcall_process):

11700 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11701 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11702 (casify_object): Avoid integer overflow when overallocating buffer.
11703 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11704 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11705 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11706 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11707 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

11713 Check that Vcode_version_map_vector is a vector.
11714 (resolve_symbol_ccl_program): Check that vector header is in range.
11715 Always copy the vector, so that we can check its contents reliably
11716 now rather than having to recheck each instruction as it's being
11717 executed. Check that vector words fit in 'int'.
11718 (ccl_get_compiled_code, Fregister_ccl_program)
11719 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11720 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11721 (Fccl_execute, Fccl_execute_on_string): Check that initial reg

11725 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):

11733 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11751 to be a character. Avoid int overflow if max_char is close

11763 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11764 where the argument is EMACS_INT, and this behavior is not intended.
11765 * chartab.c (Fmake_char_table, Fset_char_table_range)
11766 (uniprop_get_decoder, uniprop_get_encoder):
11767 Don't assume fixnum fits in int.

12393 (merge_face_heights): Remove unnecessary cast to EMACS_INT.
12394 (Finternal_make_lisp_face): Don't allocate more than MAX_FACE_ID.
12395 (face_at_buffer_position, face_for_overlay_string)
12396 (face_at_string_position):
12397 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12398 (merge_faces): Use int, not EMACS_INT, where int is wide enough.
12399 * xfns.c (x_set_menu_bar_lines, x_set_tool_bar_lines, x_icon_verify)
12401 Check that fixnums are in proper range for system types.
12402 (Fx_create_frame, x_create_tip_frame, Fx_show_tip)
12403 (Fx_hide_tip, Fx_file_dialog, Fx_select_font):
12404 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12405 (Fx_change_window_property): Don't assume fixnums fit in int.
12406 * xfont.c (xfont_chars_supported):
12407 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12408 * xmenu.c (Fx_popup_dialog, set_frame_menubar)
12409 (create_and_show_popup_menu, create_and_show_dialog, xmenu_show):
12410 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12411 * xml.c (parse_region):
12412 * xrdb.c (magic_file_p):
12413 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12414 * xselect.c (TRACE1): Don't assume pid_t promotes to int.
12415 (x_get_local_selection, x_reply_selection_request)
12416 (x_handle_selection_request, wait_for_property_change):
12417 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12418 (selection_data_to_lisp_data): Use short, not EMACS_INT, where
12419 short is wide enough.
12420 (x_send_client_event): Don't assume fixnum fits in int.
12421 * xterm.c (x_x_to_emacs_modifiers):
12422 Don't assume EMACS_INT overflows nicely into int.
12423 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
12424 may come from Lisp.
12425 (handle_one_xevent): NATNUMP can eval its arg twice.
12426 (x_connection_closed):
12427 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12428 * xterm.h: Adjust decls to match defn changes elsewhere.
12429 (struct scroll_bar): Use struct vectorlike_header
12430 rather than rolling our own approximation.
12431 (SCROLL_BAR_VEC_SIZE): Remove; not used.
12433 2012-05-25 Glenn Morris <rgm@gnu.org>
12435 * lisp.mk (lisp): Update for more files being compiled now.
12437 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
12439 * lread.c: Remove `read_pure' which makes no difference.
12440 (read_pure): Remove var.
12441 (unreadpure): Remove function.
12442 (readevalloop): Don't call read_list with -1 flag.
12443 (read1, read_vector): Don't test read_pure any more.
12444 (read_list): Simplify.
12446 * fileio.c, character.h: Minor style tweaks.
12448 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
12450 * window.h (clip_changed): Remove useless declaration.
12452 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
12454 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
12455 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
12457 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
12460 This directory predates autoconf and is no longer needed nowadays.
12461 Move its few remaining bits of functionality to where they're needed.
12462 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
12463 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
12464 * m/template.h: Remove.
12465 * Makefile.in (M_FILE): Remove. All uses removed.
12466 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
12467 * lisp.h (USE_LSB_TAG):
12468 * mem-limits.h (EXCEEDS_LISP_PTR):
12469 Use VAL_MAX, not VALBITS, in #if.
12470 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
12471 (EMACS_UINT): Define unconditionally now.
12472 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
12473 (BITS_PER_EMACS_INT): New constants, replacing
12474 what used to be in config.h, but not useful in #if.
12475 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
12476 define them any more.
12477 (VAL_MAX): New macro.
12479 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
12480 BITS_PER_EMACS_INT, in #if.
12481 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
12482 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
12483 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
12484 * s/ms-w32.h (DATA_START):
12485 Move here from removed file m/intel386.h.
12486 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
12487 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
12489 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
12491 Assume C89 or later.
12492 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
12493 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
12495 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
12496 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
12497 * textprop.c, tparam.c (NULL): Remove.
12498 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
12499 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
12500 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
12501 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
12502 * xterm.c (input_signal_count): Assume volatile works.
12504 2012-05-21 Ken Brown <kbrown@cornell.edu>
12506 * xgselect.c (xg_select): Fix first argument in call to 'select'
12509 2012-05-20 Ken Brown <kbrown@cornell.edu>
12511 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
12512 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
12514 2012-05-19 Ken Brown <kbrown@cornell.edu>
12516 * xfns.c (x_in_use): Remove `static' qualifier.
12517 * xterm.h (x_in_use): Declare.
12518 * xgselect.c: Include xterm.h.
12519 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
12520 and `display_arg' (bug#9754).
12522 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
12524 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
12526 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
12527 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
12529 2012-05-18 Eli Zaretskii <eliz@gnu.org>
12531 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
12533 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
12534 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
12536 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12537 reference to image_cache->refcount.
12538 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12540 2012-05-17 Juri Linkov <juri@jurta.org>
12542 * search.c (Fword_search_regexp, Fword_search_backward)
12543 (Fword_search_forward, Fword_search_backward_lax)
12544 (Fword_search_forward_lax): Move functions to isearch.el
12545 (bug#10145, bug#11381).
12547 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12549 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12551 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12553 * lread.c (init_obarray): Declare Qt and Qnil as special.
12555 2012-05-14 Glenn Morris <rgm@gnu.org>
12557 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12558 Put "libexec" before "bin", for the sake of init_callproc_1.
12560 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12562 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12564 * unexaix.c: Port to more-recent AIX compilers.
12565 (report_error, report_error_1, make_hdr, copy_sym)
12566 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12567 Make arguments const char *, not char *, to avoid violations of C
12568 standard and to fix some AIX warnings reported by Gilles Pion.
12570 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12572 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12573 already have overlays loaded.
12574 (handle_single_display_spec): Before returning without displaying
12575 fringe bitmap, synchronize the bidi iterator with the main display
12576 iterator, by calling iterate_out_of_display_property.
12577 (iterate_out_of_display_property): Detect buffer iteration by
12578 testing that it->string is a Lisp string.
12579 (get_next_display_element): When the current object is exhausted,
12580 and there's something on it->stack, call set_iterator_to_next to
12581 proceed with what's on the stack, instead of returning zero.
12582 (set_iterator_to_next): If called at the end of a Lisp string,
12583 proceed to consider_string_end without incrementing string
12584 position. Don't increment display vector index past the end of
12585 the display vector. (Bug#11417)
12586 (pos_visible_p): Don't report a position visible when move_it_to
12587 stopped at the last line of window, which happens to be scanned
12588 backwards by the bidi iteration. (Bug#11464)
12590 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12592 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12593 and right-margin display specs even if the spec is invalid or we
12594 are on a TTY, and thus unable to display on the fringes.
12595 That's because the text with the property will not be displayed anyway,
12596 so we need to signal to the caller that this is a "replacing"
12597 display spec. This fixes display when the spec is invalid or we
12600 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12602 * unexaix.c (make_hdr): Fix typo in prototype.
12603 This bug broke the build on AIX. Problem reported by Gilles Pion.
12605 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12607 * keyboard.c (kbd_buffer_get_event): Read special events also in
12608 batch mode. (Bug#11415)
12610 2012-05-12 Glenn Morris <rgm@gnu.org>
12612 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12614 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12616 * lisp.mk (lisp): Add newcomment.elc.
12618 2012-05-12 Glenn Morris <rgm@gnu.org>
12620 * Makefile.in (MKDIR_P): New, set by configure.
12621 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12623 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12625 Remove unused function hourglass_started.
12626 * dispextern.h (hourglass_started):
12627 * w32fns.c (hourglass_started):
12628 * xdisp.c (hourglass_started): Remove.
12630 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12632 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12633 Update dependencies.
12635 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12637 * xgselect.c (xg_select): Put maxfds+1 into a var.
12638 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12640 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12642 2012-05-10 Dave Abrahams <dave@boostpro.com>
12644 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12645 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12647 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12649 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12650 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12651 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12652 Initialize xd_registered_buses.
12654 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12656 Untag more efficiently if USE_LSB_TAG.
12657 This is based on a proposal by YAMAMOTO Mitsuharu in
12658 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12659 For an admittedly artificial (nth 8000 longlist) benchmark on
12660 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12661 Emacs's overall text size by 1%.
12662 * lisp.h (XUNTAG): New macro.
12663 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12664 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12665 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12666 * eval.c (Fautoload):
12667 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12668 * frame.h (XFRAME): Use XUNTAG.
12670 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12671 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12672 Remove unportable assumptions about print widths of types like
12674 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12675 intptr_t when converting between pointer and integer, to avoid GCC
12676 warnings about wrong width.
12678 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12680 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12681 stack for each reader_thread, instead of defaulting to 8MB
12682 determined by the linker. This avoids failures in creating
12683 subprocesses on Windows 7, see the discussion in this thread:
12684 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12686 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12688 Fix up display of the *Minibuf-0* buffer in the mini window.
12689 * keyboard.c (read_char): Don't clear the echo area if there's no
12691 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12692 contents of *Minibuf-0*) if there's no message displayed in its stead.
12694 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12696 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12699 2012-05-06 Chong Yidong <cyd@gnu.org>
12701 * lisp.mk (lisp): Update.
12703 2012-05-05 Jim Meyering <meyering@redhat.com>
12705 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12707 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12709 * data.c (PUT_ERROR): New macro.
12710 (syms_of_data): Use it. Add new error type `user-error'.
12711 * undo.c (user_error): New function.
12712 (Fprimitive_undo): Use it.
12713 * print.c (print_error_message): Adjust print style for `user-error'.
12714 * keyboard.c (user_error): New function.
12715 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12717 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12719 Do not limit current-time-string to years 1000..9999.
12720 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12721 (Fcurrent_time_string): Support any year that is supported by the
12722 underlying localtime representation. Don't use asctime, as it
12723 has undefined behavior for years outside the range -999..9999.
12725 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12727 Fix race conditions involving setenv, gmtime, localtime, asctime.
12728 Without this fix, interrupts could mess up code that uses these
12729 nonreentrant functions, since setting TZ invalidates existing
12730 tm_zone or tzname values, and since most of these functions return
12731 pointers to static storage.
12732 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12733 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12734 Grow the critical sections to include not just invoking
12735 localtime/gmtime, but also accessing these functions' results
12736 including their tm_zone values if any, and any related TZ setting.
12737 (format_time_string): Last arg is now struct tm *, not struct tm **,
12738 so that the struct tm is saved in the critical section.
12739 All callers changed. Simplify allocation of initial buffer, partly
12740 motivated by the fact that memory allocation needs to be outside
12741 the critical section.
12743 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12745 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12746 with RESET_INTERVAL.
12748 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12749 Remove duplicated buffer name initialization.
12751 2012-05-02 Jim Meyering <jim@meyering.net>
12753 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12755 * xfns.c (x_window): Use xstrdup (Bug#11375).
12757 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12759 * xdisp.c (pos_visible_p): If already at a newline from the
12760 display string before the 'while' loop, don't walk back the glyphs
12761 from it3.glyph_row. Solves assertion violation when the display
12762 string begins with a newline (egg.el). (Bug#11367)
12764 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12766 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12769 2012-05-01 Glenn Morris <rgm@gnu.org>
12771 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12772 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12773 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12774 All were removed before 23.1.
12776 * dispnew.c: Remove HAVE_LIBNCURSES test;
12777 it is always true on relevant platforms.
12779 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12780 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12782 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12784 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12786 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12787 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12790 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12792 Do not avoid creating empty evaporating overlays (Bug#9642).
12793 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12794 That is, do not delete an evaporating overlay if it becomes
12795 empty after its bounds are adjusted to fit within its buffer.
12796 This fix caused other problems, and I'm reverting it until we get
12797 to the bottom of them.
12799 2012-04-27 Chong Yidong <cyd@gnu.org>
12801 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12803 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12805 * xdisp.c (pos_visible_p): If the window start position is beyond
12806 ZV, start the display from buffer beginning. Prevents assertion
12807 violation in init_iterator when the minibuffer window is scrolled
12808 via the scroll bar.
12810 * window.c (window_scroll_pixel_based): Likewise.
12812 2012-04-27 Chong Yidong <cyd@gnu.org>
12814 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12816 2012-04-27 Glenn Morris <rgm@gnu.org>
12818 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12819 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12821 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12823 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):

12833 (add_menu_item): If the call to AppendMenuW (via
12834 unicode_append_menu) fails, disable Unicode menus only if we are
12835 running on Windows 9X/Me.
12837 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12839 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

12860 Do not create empty overlays with the evaporate property (Bug#9642).
12861 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12862 if it becomes empty after its bounds are adjusted to fit within
12863 its buffer. Without this fix, in a nonempty buffer (let ((o
12864 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12865 yields an empty overlay that has the evaporate property, which is
12866 not supposed to happen.

12889 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12890 (__malloc_size_t, __malloc_ptrdiff_t):
12891 Remove. All uses removed, replaced by the definiens if needed,
12892 since we can assume C89 or better now.

12981 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12983 * sysdep.c [__FreeBSD__]: Minor cleanups.
12984 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12985 Use Emacs indenting style more consistently. Avoid some casts.
12986 Use 'double' consistently rather than mixing 'float' and 'double'.

12999 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
13000 It is never used otherwise.
13002 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
13004 * print.c (print_preprocess): Only check print_depth if print-circle

13011 * process.c (wait_reading_process_output): If EIO occurs on a pty,
13012 set the status to "failed" and ensure that sentinel is run.
13014 2012-04-20 Glenn Morris <rgm@gnu.org>
13016 * process.c (Fset_process_inherit_coding_system_flag)
13017 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

13045 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
13046 -Wunused-result, -Wunused-variable. This should go away once
13047 the Emacs and Gnulib regex code is merged.

13067 New extern decls, to avoid calling undeclared functions.
13068 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
13069 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
13070 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13071 (NEED_MEM_INSERT): New macro.
13072 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13073 Remove one incorrect comment and fix another.

13109 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
13110 * s/netbsd.h, s/sol2-6.h:
13111 Remove definition of GC_MARK_STACK, since the default now works.
13112 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

13140 2012-04-11 Daniel Colascione <dancol@dancol.org>
13142 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13143 against is gone. It's better to use vfork now so that when Cygwin
13144 gains a new, working vfork, we use it automatically (bug#10398).
13146 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

13187 (emacs_gnutls_read): Use new log functions,
13188 `gnutls_handshakes_tried' process member, and
13189 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
13190 attempts per process (connection).
13192 2012-04-09 Chong Yidong <cyd@gnu.org>
13194 * eval.c (Fuser_variable_p, user_variable_p_eh)

13196 (Fdefvar): Caller changed.
13198 * callint.c (Finteractive, Fcall_interactively):
13199 * minibuf.c (Fread_variable): Callers changed.
13201 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13203 * xdisp.c (set_cursor_from_row): If the display string appears in
13204 the buffer at position that is closer to point than the position
13205 after the display string, display the cursor on the first glyph of
13206 the display string. Fixes cursor display when a 'display' text
13207 property immediately follows invisible text. (Bug#11094)
13209 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13211 composite.c: use 'double' consistently
13212 * composite.c (get_composition_id): Use 'double' consistently
13213 instead of converting 'float' to 'double' and vice versa; this is
13214 easier to understand and avoids a GCC warning.
13216 2012-04-09 Glenn Morris <rgm@gnu.org>
13218 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13219 preparation for dumping it with emacs. (Bug#4789)

13254 Support building on MS-Windows with libxml2.
13256 * makefile.w32-in (OBJ2): Add xml.$(O).
13257 (GLOBAL_SOURCES): Add xml.c.
13258 ($(BLD)/xml.$(O)): New dependency list.
13260 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
13261 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
13262 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
13263 [!WINDOWSNT]: New macros.
13264 (init_libxml2_functions, libxml2_loaded_p): New functions.
13265 (parse_region): Call fn_xmlCheckVersion instead of using the macro
13266 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
13267 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
13268 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13270 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13271 Call init_libxml2_functions before calling libxml2 functions.
13272 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13274 * emacs.c: Don't include libxml/parser.h.
13275 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
13276 xmlCleanupParser directly.
13278 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
13280 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13282 * indent.c (Fvertical_motion): If there is a display string at
13283 point, use it.vpos to compute how many lines to backtrack after
13284 move_it_to point. (Bug#11133)
13286 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13288 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13289 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13290 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13291 macros related to unification of CJK characters. For the details,
13292 see the discussion following the message here:
13293 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
13295 2012-04-04 Chong Yidong <cyd@gnu.org>
13297 * keyboard.c (Vdelayed_warnings_list): Doc fix.
13299 2012-04-01 Eli Zaretskii <eliz@gnu.org>
13301 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
13302 instead of alloca. (Bug#11138)
13304 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
13306 * w32menu.c (is_simple_dialog): Properly check lisp types.
13309 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13311 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13312 position we get to after a call to move_it_to fails the
13313 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13314 only if we wind up in a string from display property. (Bug#11063)
13316 * window.c (Fdelete_other_windows_internal): Invalidate the row
13317 and column information about mouse highlight, so that redisplay
13318 restores it after reallocating the glyph matrices. (Bug#7464)
13320 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13321 string comes from a `display' text property, use the buffer
13322 position of that property as if we actually saw that position in
13324 (move_it_by_lines): Remove the assertion that
13325 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13326 violated when there's a before-string at the beginning of a line.
13329 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13331 * xdisp.c (append_space_for_newline): If the default face was
13332 remapped, use the remapped face for the appended newline.
13333 (extend_face_to_end_of_line): Use the remapped default face for
13334 extending the face to the end of the line.
13335 (display_line): Call extend_face_to_end_of_line when the default
13336 face was remapped. (Bug#11068)
13338 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13340 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
13342 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13344 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
13346 2012-03-27 Glenn Morris <rgm@gnu.org>
13348 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
13351 2012-03-26 Kenichi Handa <handa@m17n.org>
13353 * dispextern.h (struct glyph): Fix previous change. Change the
13354 bit length of glyphless.ch to 25 (Bug#11082).
13356 2012-03-26 Chong Yidong <cyd@gnu.org>
13358 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13359 (command_loop_1): Use it; inhibit selection update for
13360 handle-select-window too (Bug#8996).
13362 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
13364 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13366 2012-03-25 Kenichi Handa <handa@m17n.org>
13368 * dispextern.h (struct glyph): Change the bit length of
13369 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13371 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13373 * s/ms-w32.h (tzname): Include time.h before redirecting to
13374 _tzname. Fixes the MSVC build. (Bug#9960)
13376 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
13378 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13381 * xterm.c (XTread_socket): Only modify handling_signal if
13382 !SYNC_INPUT. (Bug#11080)
13384 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13386 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13387 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13388 when fetching a multibyte character consumes more bytes than
13389 CHAR_BYTES returns, due to unification of CJK characters in
13390 string_char. (Bug#11073)
13392 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13394 * process.c (wait_reading_process_output): Handle pty disconnect
13395 by refraining from sending oneself a SIGCHLD (bug#10933).
13397 2012-03-22 Chong Yidong <cyd@gnu.org>

13401 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
13402 Mark string as coming from a prefix property.
13403 (handle_face_prop): Use default face for prefix strings (Bug#4281).
13404 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
13406 2012-03-21 Chong Yidong <cyd@gnu.org>
13408 * xfaces.c (Vface_remapping_alist): Doc fix.
13410 2012-03-20 Eli Zaretskii <eliz@gnu.org>
13412 * w32proc.c (Fw32_set_console_codepage)
13413 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
13416 2012-03-20 Chong Yidong <cyd@gnu.org>
13418 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
13419 to reflect default non-nil value of redisplay-dont-pause.
13421 2012-03-19 Kenichi Handa <handa@m17n.org>
13423 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
13424 it fit in a valid range (Bug#11003).
13426 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13428 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13429 that is not from display property, accept the row as a "cursor
13430 row" if one of the string's character has a non-nil `cursor'
13431 property. Fixes cursor positioning when there are newlines in
13432 overlay strings, e.g. in icomplete.el. (Bug#11035)
13434 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13436 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13438 2012-03-12 Chong Yidong <cyd@gnu.org>
13440 * eval.c (inhibit_lisp_code): Rename from
13441 inhibit_window_configuration_change_hook; move from window.c.
13443 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13444 * window.c (run_window_configuration_change_hook)
13445 (syms_of_window): Callers changed.

13455 * frame.c (other_visible_frames): Don't assume the selected frame
13456 is visible (Bug#10955).
13458 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
13460 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
13462 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
13464 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
13465 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13468 2012-03-03 Glenn Morris <rgm@gnu.org>
13470 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13472 2012-03-02 Eli Zaretskii <eliz@gnu.org>
13474 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
13475 position past the first glyph_row that ends at ZV. (Bug#10902)
13476 (redisplay_window, next_element_from_string): Fix typos in
13478 (redisplay_window): Pass to move_it_vertically the margin in
13479 pixels, not in screen lines.
13481 2012-03-02 Glenn Morris <rgm@gnu.org>
13483 * buffer.c (buffer-list-update-hook): Doc fix.
13485 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13487 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13488 push_it before setting up the iterator for the first overlay
13489 string, even if we have an empty string loaded.
13490 (next_overlay_string): If there's an empty string on the iterator
13491 stack, pop the stack. (Bug#10903)
13493 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13495 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13496 Suggested by Stefan Monnier in
13497 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13498 * alloc.c (widen_to_Lisp_Object): New static function.
13499 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13500 and widening them to Lisp_Objects. This would work even if
13501 USE_LSB_TAG is defined and wide integers are used, which might
13502 happen in a future version of Emacs.
13504 2012-02-25 Chong Yidong <cyd@gnu.org>
13506 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13509 * xselect.c (Fx_selection_exists_p): Doc fix.
13510 (x_clipboard_manager_save_all): Print an informative message
13511 before saving to clipboard manager.
13513 2012-02-24 Chong Yidong <cyd@gnu.org>
13515 * keyboard.c (process_special_events): Handle all X selection
13516 requests in kbd_buffer, not just the next one (Bug#8869).
13518 2012-02-23 Chong Yidong <cyd@gnu.org>
13520 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13521 call when setting menu-bar-lines and tool-bar-lines parameters.
13522 (unwind_create_frame_1): New helper function.
13524 * window.c (inhibit_window_configuration_change_hook): New var.
13525 (run_window_configuration_change_hook): Obey it.
13526 (syms_of_window): Initialize it.
13528 2012-02-22 Chong Yidong <cyd@gnu.org>
13530 * xterm.c (x_draw_image_relief): Add missing type check for
13531 Vtool_bar_button_margin (Bug#10743).
13533 2012-02-21 Chong Yidong <cyd@gnu.org>
13535 * fileio.c (Vfile_name_handler_alist): Doc fix.
13537 * buffer.c (Fget_file_buffer): Protect against invalid file
13538 handler return value.
13540 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
13542 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
13543 when computing $valmask.
13545 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13546 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13547 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13548 It's useless in that case, and it can cause problems on hosts
13549 that allocate halves of EMACS_INT values separately.
13550 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13551 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13552 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13553 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13554 it avoids undefined behavior on hosts where shifting right by more
13555 than the word width has undefined behavior.
13557 2012-02-19 Chong Yidong <cyd@gnu.org>
13559 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13560 (Funhandled_file_name_directory, Ffile_name_as_directory)
13561 (Fdirectory_file_name, Fexpand_file_name)
13562 (Fsubstitute_in_file_name): Protect against invalid file handler
13563 return values (Bug#10845).
13565 2012-02-18 Eli Zaretskii <eliz@gnu.org>
13567 * .gdbinit (pitx): Fix incorrect references to fields of the
13570 2012-02-17 Chong Yidong <cyd@gnu.org>
13572 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
13574 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
13576 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
13577 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
13579 2012-02-15 Chong Yidong <cyd@gnu.org>
13581 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
13582 marked as special. Also, starting docstrings with * is obsolete.
13584 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
13586 * gnutls.c (emacs_gnutls_write): Fix last change.
13588 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
13590 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
13593 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
13595 * keymap.c (Fsingle_key_description): Handle char ranges.
13597 2012-02-12 Chong Yidong <cyd@gnu.org>
13599 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13600 as that creates a dangerous corner case.
13602 * window.c (Fdelete_window_internal): Invalidate the mouse
13603 highlight (Bug#9904).
13605 2012-02-12 Glenn Morris <rgm@gnu.org>
13607 * xselect.c (Fx_own_selection_internal)
13608 (Fx_get_selection_internal, Fx_disown_selection_internal)
13609 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
13610 * nsselect.m (Fx_own_selection_internal)
13611 (Fx_disown_selection_internal, Fx_selection_exists_p)
13612 (Fx_selection_owner_p, Fx_get_selection_internal):
13613 Sync docs and argument specs with the xselect.c versions.
13615 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
13617 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
13619 2012-02-11 Eli Zaretskii <eliz@gnu.org>
13621 * w32select.c (Fx_selection_exists_p): Sync doc string and
13622 argument list with xselect.c. (Bug#10783)
13624 * w16select.c (Fx_selection_exists_p): Sync doc string and
13625 argument list with xselect.c. (Bug#10783)
13627 2012-02-10 Glenn Morris <rgm@gnu.org>
13629 * fns.c (Fsecure_hash): Doc fix.
13631 2012-02-09 Kenichi Handa <handa@m17n.org>
13633 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
13635 2012-02-07 Chong Yidong <cyd@gnu.org>
13637 * buffer.c (Fbuffer_local_variables)
13638 (buffer_lisp_local_variables): Handle unbound vars correctly;
13639 don't let Qunbound leak into Lisp.
13641 2012-02-07 Glenn Morris <rgm@gnu.org>
13643 * image.c (Fimagemagick_types): Doc fix.
13645 * image.c (imagemagick-render-type): Change it from a lisp object
13646 to an integer. Move the doc here from the lisp manual.
13647 Treat all values not equal to 0 the same.
13649 2012-02-06 Chong Yidong <cyd@gnu.org>
13651 * doc.c (store_function_docstring): Avoid applying docstring of
13652 alias to base function (Bug#2603).
13654 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
13656 * .gdbinit (pp1, pv1): Remove redundant defines.
13659 2012-02-04 Chong Yidong <cyd@gnu.org>
13661 * nsterm.m: Declare a global (Bug#10694).
13663 2012-02-04 Eli Zaretskii <eliz@gnu.org>
13665 * w32.c (get_emacs_configuration_options):
13666 Include --enable-checking, if specified, in the return value.
13668 2012-02-04 Martin Rudalics <rudalics@gmx.at>
13670 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
13671 after rounding frame sizes. (Bug#9723)
13673 2012-02-04 Eli Zaretskii <eliz@gnu.org>
13675 * keyboard.c (adjust_point_for_property): Don't position point
13676 before BEGV. (Bug#10696)
13678 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
13680 Handle overflow when computing char display width (Bug#9496).
13681 * character.c (char_width): Return EMACS_INT, not int.
13682 (char_width, c_string_width): Check for overflow when
13683 computing the width; this is possible now that individual
13684 characters can have unbounded width. Problem introduced
13685 by merge from Emacs 23 on 2012-01-19.
13687 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
13689 * dbusbind.c (Fdbus_register_method): Mention the return value
13690 :ignore in the docstring.
13692 2012-02-02 Glenn Morris <rgm@gnu.org>
13694 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.
13696 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:
13697 Unconditionally set to t. (Bug#10673)

13699 * w32term.c (syms_of_w32term) <x-toolkit-scroll-bars>:
13700 * xterm.c (syms_of_xterm) <x-toolkit-scroll-bars>: Doc fix.
13702 2012-02-02 Kenichi Handa <handa@m17n.org>
13704 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
13705 0, do not call append_composite_glyph.
13707 2012-02-02 Kenichi Handa <handa@m17n.org>
13709 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
13711 (x_produce_glyphs): If the component of a composition is a null
13712 string, set it->pixel_width to 1 to avoid zero-width glyph.
13714 2012-02-01 Eli Zaretskii <eliz@gnu.org>
13716 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
13717 first 2 arguments are identical. This makes inserting large
13718 output from a subprocess an order of magnitude faster on
13719 MS-Windows, where all sbrk'ed memory is always contiguous.
13721 2012-01-31 Glenn Morris <rgm@gnu.org>
13723 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

14249 * xdisp.c (redisplay_window): If cursor row is not fully visible
14250 after recentering, and scroll-conservatively is set to a large
14251 number, scroll window by a few more lines to make the cursor fully
14252 visible and out of scroll-margin. (Bug#10105)
14253 (start_display): Don't move to the next line if the display should
14254 start at a newline that is part of a display vector or an overlay
14255 string. (Bug#10119)

14338 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
14339 is set, removing the need for VIRT_ADDRESS_VARIES.
14340 (PURE_P): Use a more-efficient implementation that needs just one
14341 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
14342 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
14343 to 4 (xorl, subq, cmpq, setbe).
14344 * alloc.c (pure): Always extern now, since that's the
14345 VIRT_ADDR_VARIES behavior.

14347 consistency with the new puresize.h.
14348 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
14349 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

14355 (erase_phys_cursor, update_window_cursor, show_mouse_face)
14356 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
14357 behave as if the cursor position were at the window margin.
14359 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14360 and the cursor position is out of bounds, behave as if the cursor
14361 position were at the window margin. (Bug#10075)
14363 2011-11-18 Chong Yidong <cyd@gnu.org>
14365 * window.c (Fwindow_combination_limit): Make first argument

14384 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
14386 * xdisp.c (row_hash): New function, body extracted from
14387 compute_line_metrics.
14388 (compute_line_metrics): Call row_hash, instead of computing the
14391 * dispnew.c (verify_row_hash): Call row_hash for computing the
14392 hash code of a row, instead of duplicating code from xdisp.c.
14394 * dispextern.h (row_hash): Add prototype.
14396 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
14398 * frame.c (delete_frame): Don't delete the terminal when the last

14424 (Fsplit_window_internal, saved_window)
14425 (Fset_window_configuration, save_window_save): Rename all
14426 occurrences of window_nest to window_combination_limit.

14432 2011-11-14 Eli Zaretskii <eliz@gnu.org>
14434 * xdisp.c (display_line): Move the call to
14435 highlight_trailing_whitespace before the call to
14436 compute_line_metrics, since the latter needs to see the final
14437 faces of all the glyphs to compute ROW's hash value.
14438 Fixes assertion violations in row_equal_p. (Bug#10035)
14440 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
14442 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
14443 just return (bug#10044).
14445 2011-11-12 Eli Zaretskii <eliz@gnu.org>
14447 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14448 with user-defined heap size. Bump the default size of the temacs
14449 heap to 27MB, to avoid memory warning when running temacs.

14452 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
14453 current_matrix and desired_matrix. (Bug#9990)
14454 (verify_row_hash) [XASSERTS]: New function.
14455 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify

14501 Avoid some portability problems by eschewing 'extern inline' functions.
14502 The trivial performance wins aren't worth the portability hassles; see
14503 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14505 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

14571 * xmenu.c (cleanup_widget_value_tree): New function.
14572 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
14573 calling free_menubar_widget_value_tree directly (Bug#9830).

14579 (window_box_width, window_box_left, window_box_left_offset)
14580 (window_box_right, window_box_right_offset): Declare extern.
14581 Otherwise, these inline functions do not conform to C99 and
14582 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14583 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14584 * intervals.c (adjust_intervals_for_insertion)

14587 (static_offset_intervals): Remove.
14588 (offset_intervals): Rewrite using the old contents of
14589 static_offset_intervals. The old version didn't conform to C99
14590 because an extern inline function contained a reference to an
14591 identifier with static linkage.

14644 (unwind_create_frame): New function (Bug#9943).
14645 (Fx_create_frame): Restructure code to be more similar to the one in
14646 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).

14693 * regex.c <re_char> [_MSC_VER]: A separate definition for MSVC.
14695 2011-11-04 Eli Zaretskii <eliz@gnu.org>
14697 * xdisp.c (note_mouse_highlight): If either of
14698 previous/next-single-property-change returns nil, treat that as
14699 the beginning or the end of the buffer. (Bug#9955)
14701 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
14703 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
14704 label is not null (Bug#9951).

14723 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
14724 Don't stop backward scan on the continuation glyph, even though
14725 its CHARPOS is positive.
14726 (mouse_face_from_buffer_pos, note_mouse_highlight):
14727 Rename cover_string to disp_string.
14729 2011-11-01 Martin Rudalics <rudalics@gmx.at>
14731 * window.c (temp_output_buffer_show): Don't use
14732 Vtemp_buffer_show_specifiers.
14733 (Vtemp_buffer_show_specifiers): Remove unused variable.
14735 2011-10-30 Eli Zaretskii <eliz@gnu.org>
14737 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
14738 past the beginning of the current glyph matrix.
14740 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
14742 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
14743 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
14744 HAVE_GTK3 (Bug#9869).

14753 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
14754 (get_current_wm_state): Return non-zero if not hidden,

14762 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
14763 so that this new function doesn't get optimized away by a
14764 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
14766 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
14768 * frame.h (MOUSE_HL_INFO): Remove excess parens.

14786 2011-10-29 Glenn Morris <rgm@gnu.org>
14788 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
14789 Not clear what it was for, and it causes various bugs. (Bug#9839)
14791 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14793 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
14794 possible random value that matches one of those tested as
14795 condition to clear the mouse face.
14797 2011-10-28 Chong Yidong <cyd@gnu.org>
14799 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.

14809 2011-10-28 Juanma Barranquero <lekktu@gmail.com>

14813 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14815 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
14816 <oslsachem@gmail.com> for helping to debug this.
14818 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)

14824 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
14826 (w32font_open_internal, compute_metrics):
14827 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14828 instead of calling the "wide" APIs directly.
14830 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
14832 * w32.h (syms_of_w32font): Add prototype.
14834 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

14837 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
14838 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14839 (Fmove_to_window_line): Doc fix.
14841 2011-10-27 Chong Yidong <cyd@gnu.org>
14843 * process.c (make_process): Set gnutls_state to NULL.
14845 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14846 non-NULL, regardless of GNUTLS_INITSTAGE.
14847 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
14848 an error. Set process slots as soon as we allocate them.
14850 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
14852 2011-10-27 Chong Yidong <cyd@gnu.org>
14854 * gnutls.c (emacs_gnutls_deinit): New function.

14859 (deactivate_process): Call emacs_gnutls_deinit.
14861 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14863 * image.c (x_create_x_image_and_pixmap):
14864 * w32.c (sys_rename, w32_delayed_load):
14865 * w32font.c (fill_in_logfont):

14871 extracted from Fw32_default_color_map.
14872 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
14874 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14876 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
14878 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
14880 * keyboard.c (test_undefined): New function (bug#9751).
14881 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
14883 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
14885 * sysdep.c (init_sys_modes): Fix the check for the controlling
14886 terminal (Bug#6649).
14888 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14890 * dispextern.h (struct bidi_it): New member next_en_type.
14892 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14893 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14894 current character, check also for next_en_type being WEAK_EN.
14895 (bidi_resolve_weak): Don't enter the expensive loop if the current
14896 position is before next_en_pos. Record the bidi type of the first
14897 non-ET, non-BN character we find, in addition to its position.
14898 (bidi_level_of_next_char): Invalidate next_en_type when
14899 next_en_pos is over-stepped.
14901 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14903 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14904 * editfns.c: Rewrite current-time-zone so that it invokes
14905 the equivalent of (format-time-string "%Z") to get the time zone name.
14906 This fixes a bug when the time zone name contains characters that
14907 need converting from the system time locale to Emacs internal format.
14908 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14909 that patch fixed format-time-string to do the conversion, but
14910 I forgot to fix current-time-zone.
14911 (format_time_string): New function, containing most of
14912 what Fformat_time_string used to contain.
14913 (Fformat_time_string): Rewrite in terms of format_time_string.
14914 This doesn't change this function's behavior.
14915 (current-time-zone): Rewrite to use format_time_string.
14916 This fixes the bug reported by Michael Schierl in
14917 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14918 Jason Rumney's 2007-06-07 change worked around this bug, but
14920 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14922 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14924 * xdisp.c (start_display): If the character at POS is displayed
14925 via a display vector, reset IT->current.dpvec_index to zero.
14926 (try_window_reusing_current_matrix): If a line ends in a display
14927 vector or the next line starts in a display vector, continue
14928 redrawing the window even though the character position of
14929 start_row was reached.
14932 2011-10-18 Chong Yidong <cyd@gnu.org>
14934 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14935 with nobreak-char-display too.
14937 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14939 Fix part 3 of bug#9771.
14940 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14941 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14942 non-neutral characters if the current character is a paragraph
14943 separator (a.k.a. Newline). This avoids running the same
14944 expensive loop twice, once when we consume the preceding newline
14945 and the other time when the line actually needs to be displayed.
14946 Avoid the loop when we see neutrals on the base embedding level
14947 following a character whose directionality is the same as the
14948 paragraph's. This avoids running the expensive loop when a line
14949 ends in a long sequence of neutrals, like control characters.
14950 Add assertion against STRONG_AL type. Slightly rearrange code
14951 that determines the type of a neutral given the first non-neutral
14953 (bidi_level_of_next_char): Set next_en_pos to zero when
14954 invalidating its info.
14956 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14958 * xdisp.c (push_display_prop): Determine whether to record string
14959 or buffer position by IT->string, not by IT->method. Allow
14960 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14961 (move_it_vertically_backward): Don't look for character position
14962 immediately after the newline when in a continuation line.
14965 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14967 * window.c (coordinates_in_window): Rewrite and delabelize
14968 vertical border check. (Bug#5357) (Bug#9618)
14970 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14972 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14973 errors in XSetWindowBorder (bug#9310).
14975 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14977 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14978 avoid crash when xmalloc overrun checking is enabled.
14980 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14982 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14983 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14984 cursor motion with <left> and <right> arrow keys.
14986 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14987 some callers set that themselves.
14989 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14991 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14992 display string and the previous row comes from the same string and
14993 is empty. (Bug#9739) (Bug#9738)
14995 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14997 * doc.c (get_doc_string): Encode file name (bug#9735).
14999 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15001 * bidi.c (bidi_level_of_next_char):
15002 * xdisp.c (get_visually_first_element): Remove old incorrect
15003 comments regarding the Unicode Line Separator character.
15005 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15007 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15009 * alloc.c (Fgc_status): Do not access beyond zombies array
15010 boundary if nzombies > MAX_ZOMBIES.
15011 * alloc.c (dump_zombies): Add missing format specifier.
15013 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15015 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15016 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15018 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15019 Some packages use them to denote characters with modifiers.
15021 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15023 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15024 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15025 matching a pp-number. Rename parameter var to var1.
15027 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15029 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15031 2011-10-08 Glenn Morris <rgm@gnu.org>
15033 * callint.c (Fcall_interactively): Give a more explicit error for the
15034 'c' case with a non-character input. (Bug#8479)
15036 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15038 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15040 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15041 lines that are hscrolled on the left.
15043 * dispnew.c (buffer_posn_from_coords): Account for a possible
15044 presence of header-line. (Bug#4426)
15046 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15048 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15049 Don't advertise functionality which we discourage or doesn't work.
15051 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15053 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15054 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15055 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15056 this makes Emacs dump core during garbage collection on rare
15057 occasions. sizeof is obviously inferior to offsetof here, so
15058 stick with offsetof.
15059 (GC_POINTER_ALIGNMENT): New macro.
15060 (mark_memory): Omit 3rd (offset) arg; caller changed.
15061 Don't assume EMACS_INT alignment is the same as pointer alignment.
15063 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15065 * keyboard.c (read_key_sequence_remapped): New var.
15066 (read_key_sequence): Compute remapping in the right buffer.
15067 (command_loop_1): Use read_key_sequence's remapping directly.
15069 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15071 * dired.c (file_name_completion): Don't expand file name.
15072 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15073 before checking file name handler.
15075 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15076 they've been requested explicitly (bug#9591).
15078 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15080 * keymap.c (Fsingle_key_description): Use make_specified_string
15081 instead of build_string to build string from push_key_description.
15084 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15086 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15087 This fixes a Y2038 bug on 64-bit hosts.
15088 * buffer.c (reset_buffer):
15089 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15090 (Fclear_buffer_auto_save_failure):
15091 Use 0, not -1, to represent an unset failure time, since time_t
15092 might not be signed.
15094 Remove dependency on glibc malloc internals.
15095 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15096 Move back here from lisp.h, but with their new implementations.
15097 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15098 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15099 * charset.c (charset_table_init): New static var.
15100 (syms_of_charset): Use it instead of xmalloc. This removes a
15101 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15102 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15103 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15104 Move back to alloc.c.
15105 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15106 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15108 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15110 * nsterm.m (windowDidResize): Call x_set_window_size only when
15111 ns_in_resize is true. Otherwise set pixelwidth/height and
15112 call change_frame_size (Bug#9628).
15114 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15116 Port --enable-checking=all to Fedora 14 x86-64.
15117 * charset.c (syms_of_charset): Also account for glibc malloc's
15118 internal overhead when calculating the initial malloc maximum.
15120 Port --enable-checking=all to Fedora 14 x86.
15121 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15123 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15124 (overrun_check_realloc, overrun_check_free):
15125 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15126 That way, xmalloc returns a properly-aligned pointer even if
15127 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15128 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15129 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15130 into account when calculating the initial malloc maximum.
15131 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15132 Move here from alloc.c, so that charset.c can use it too.
15133 Properly align; the old code wasn't right for common 32-bit hosts
15134 when configured with --enable-checking=all.
15135 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15136 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15138 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15140 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15143 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15145 * xdisp.c (compute_display_string_end): If there's no display
15146 string at CHARPOS, return -1.
15148 * bidi.c (bidi_fetch_char): When compute_display_string_end
15149 returns a negative value, treat the character as a normal
15150 character not covered by a display string. (Bug#9624)
15152 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15154 * lread.c (Fread_from_string): Fix typo in docstring.
15156 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15158 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15159 newline, reseat the iterator instead of bidi-iterating there one
15160 character at a time. (Bug#9610)
15161 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15162 TO_CHARPOS if the bidi iterator is at base embedding level.
15164 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15166 * lread.c (readevalloop): Use correct code for NBSP.
15167 (read1): Likewise. (Bug#9608)
15169 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15171 * dbusbind.c (Fdbus_register_signal): When service is not
15172 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15174 2011-09-25 Glenn Morris <rgm@gnu.org>
15176 * buffer.c (truncate-lines): Doc fix.
15178 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15180 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15181 (Fset_window_next_buffers): Doc fix.
15183 2011-09-24 Glenn Morris <rgm@gnu.org>
15185 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15187 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15189 Fix minor problems found by static checking.
15190 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
15191 * indent.c (Fvertical_motion): Fix == vs = typo.
15193 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15195 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15196 Default value is now t. Doc fix.
15198 * indent.c (Fvertical_motion): Compute and apply the overshoot
15199 logic when moving up, not only when moving down. Fix the
15200 confusing name and values of the it_overshoot_expected variable;
15201 logic changes accordingly. (Bug#9254) (Bug#9549)
15203 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15204 CHARPOS is covered by a display string which includes newlines.
15205 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15206 is covered by a display string with embedded newlines.
15208 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15210 * dbusbind.c (Fdbus_register_signal): Add match rule to
15211 Vdbus_registered_objects_table. (Bug#9581)
15212 (Fdbus_register_method, Vdbus_registered_objects_table):
15215 2011-09-24 Jim Meyering <meyering@redhat.com>
15217 do not ignore write error for any output size
15218 The previous change was incomplete.
15219 While it makes emacs --batch detect the vast majority of stdout
15220 write failures, errors were still ignored whenever the output size is
15221 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15222 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15223 && echo FAIL: ignored write error
15224 FAIL: ignored write error
15225 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15226 && echo FAIL: ignored write error
15227 FAIL: ignored write error
15228 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15230 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15232 * emacs.c (Fkill_emacs): In noninteractive mode exit
15233 non-successfully if a write error occurred on stdout. (Bug#9574)
15235 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15237 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15240 * dispextern.h (struct it): Update the comment documenting what
15243 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15245 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15246 a display string, extend search for cursor position to end of row.
15247 (find_row_edges): If the row ends in a newline from a display
15248 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15249 Handle the case of a display string with multiple newlines.
15250 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15251 non-empty line. Fixes confusing cursor motion with arrow keys at
15252 the beginning of a line that starts with whitespace.
15254 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15256 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15259 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15261 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15262 boolean (Bug#9154).
15264 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15266 * xdisp.c (display_line): Record maximum and minimum buffer
15267 positions even if no glyphs were produced (e.g., by a zero-width
15268 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15269 buffer positions that will be removed from the glyph row because
15271 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15272 column is beyond frame width: don't subtract 1 "pixel" when
15273 computing width of the stretch.
15274 (reseat_at_next_visible_line_start): Undo the change made on
15275 2011-09-17 that saved paragraph information and restored it after
15276 the call to `reseat'. (Bug#9545)
15278 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15280 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15281 and turn window cursor on if cleared (Bug#9415).
15283 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15285 * search.c (boyer_moore): Take unibyte characters from pattern
15286 literally. (Bug#9458)
15288 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15290 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
15292 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
15294 Fix minor problem found by static checking.
15295 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
15296 initialized, to pacify gcc -Wuninitialized.
15298 * fileio.c: Report proper errno when syscall falls.
15299 (Finsert_file_contents): Save and restore errno,
15300 so that report_file_error outputs the correct diagnostic.
15301 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15303 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15305 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15307 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15309 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15310 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
15312 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15314 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15315 about the current paragraph and restore it after the call to reseat.
15317 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15318 (bidi_find_paragraph_start): Search back for paragraph beginning
15319 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15320 (bidi_move_to_visually_next): Only trigger paragraph-related
15321 computations when the last character is a newline or at EOB, not
15322 just any NEUTRAL_B. (Bug#9470)
15324 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15325 truncated lines if point is covered by a display string. (Bug#9524)
15327 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15329 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15330 (cons_to_x_long): New function.
15331 (lisp_data_to_selection_data): Use it. Correct the test for
15332 short-versus-long data; it was negated. Break out of vector
15333 loop, for efficiency, when a long datum is discovered.
15335 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15337 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15339 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15341 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
15342 GCC PR/17406) by declaring this function with external scope.
15344 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15346 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
15347 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
15349 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
15351 * editfns.c (Fformat): Correctly handle text properties on "%%".

15359 * xdisp.c (get_next_display_element)
15360 (fill_composite_glyph_string): Add comments about special meaning
15361 of TAB characters in a composition.
15363 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15365 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15366 This occurs when processing a multibyte format.
15367 Problem reported by Wolfgang Jenker.
15369 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15371 * xdisp.c (try_cursor_movement): Only check for exact match if
15372 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15374 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15376 Remove unused external symbols.
15377 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15378 * xdisp.c (calc_pixel_width_or_height): Now static.
15379 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
15380 * indent.c (check_display_width):
15381 * w32term.c: Fix comment to match code.
15382 * xterm.c, xterm.h (x_catching_errors): Remove.
15384 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15386 * xselect.c: Use signed conversions more consistently (Bug#9498).
15387 (selection_data_to_lisp_data): Assume incoming selection data are
15388 signed integers, not unsigned. This is to be consistent with
15389 outgoing selection data, which was modified to use signed integers
15390 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15391 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15392 expects long, not unsigned long.
15394 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15396 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15397 computation of loop end. Reported by Johan Bockgård
15400 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15402 * frame.c (Fother_visible_frames_p): Function deleted.
15404 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15406 * indent.c (compute_motion): Process display vector front to back
15407 rather than the other way around. (Bug#2496)
15409 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15411 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15413 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15415 * minibuf.c (Fread_from_minibuffer): Doc fix.
15417 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15419 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15420 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15422 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15424 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15425 value for non-existent files.
15427 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15429 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15430 set its "size" to -1. This will set the modtime_size field of
15431 the corresponding buffer to -1, which is what
15432 verify-visited-file-modtime expects for files that do not exist.
15435 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15437 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15439 * lisp.h: ... from here. push_key_description is no longer
15440 defined in keyboard.c, so its declaration should not be in
15441 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15442 logically belongs with push_key_description.
15444 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15446 * buffer.h: Include <sys/types.h> instead of <time.h>.
15447 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15448 Problem reported by Herbert J. Skuhra.
15450 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15452 * xml.c (parse_region): Make the parsing work for
15453 non-comment-starting XML files again (bug#9144).
15455 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15457 * image.c (gif_load): Fix calculation of bottom and right corner.
15460 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15462 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15463 redisplay in small windows.
15465 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15467 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15469 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15471 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15472 Operate on live windows only.
15474 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15476 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15478 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15480 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15481 only under bidi iteration.
15483 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15485 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15487 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15489 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15490 Without this fix, the command to link temacs failed due to an
15491 undefined symbol __builtin_isnan. This is because
15492 /usr/include/iso/math_c99.h #defines isnan(x) to
15493 __builtin_isnan(x), but the bundled gcc, which identifies itself
15494 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15496 * floatfns.c (isnan): #undef, and then #define to a clone of
15498 (Fisnan): Always define, since it's always available now.
15499 (syms_of_floatfns): Always define isnan at the Lisp level.
15501 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15503 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15505 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15507 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15508 The previous code assumed that file offsets (off_t values) fit in
15509 EMACS_INT variables, which is not true on typical 32-bit hosts.
15510 The code messed up by falsely reporting buffer overflow in cases
15511 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15512 when "big" contains more than 2**29 bytes, even though this
15513 inserts just one byte and does not overflow the buffer.
15514 (Finsert_file_contents): Store file offsets as off_t
15515 values, not as EMACS_INT values. Check for overflow when
15516 converting between EMACS_INT and off_t. When checking for
15517 buffer overflow or for overlap, take the offsets into account.
15518 Don't use EMACS_INT for small values where int suffices.
15519 When checking for overlap, fix a typo: ZV was used where
15520 ZV_BYTE was intended.
15521 (Fwrite_region): Don't assume off_t fits into 'long'.
15522 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15524 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15526 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15528 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15530 sprintf-related integer and memory overflow issues (Bug#9412).
15532 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15533 (esprintf, exprintf, evxprintf): New functions.
15534 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15535 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15536 (modify_event_symbol): Do not assume that the length of
15537 name_alist_or_stem is safe to alloca and fits in int.
15538 (Fexecute_extended_command): Likewise for function name and binding.
15539 (Frecursion_depth): Wrap around reliably on integer overflow.
15540 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15541 since some callers pass EMACS_INT values.
15542 (Fsingle_key_description): Don't crash if symbol name contains more
15543 than MAX_ALLOCA bytes.
15544 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15545 (get_minibuffer): Arg is now EMACS_INT, not int.
15546 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15547 (esprintf, exprintf, evxprintf): New decls.
15548 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15550 * dbusbind.c (signature_cat): New function.
15551 (xd_signature, Fdbus_register_signal):
15552 Do not overrun buffer; instead, report string overflow.
15554 * dispnew.c (add_window_display_history): Don't overrun buffer.
15555 Truncate instead; this is OK since it's just a log.
15557 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15558 even if the time zone offset is outlandishly large.
15559 Don't mishandle offset == INT_MIN.
15561 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15562 when creating daemon; the previous buffer-overflow check was incorrect.
15564 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15565 which has the guts of the old verror function.
15567 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15568 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15570 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15571 (font_unparse_xlfd): Don't blindly alloca long strings.
15572 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15573 fits in int, when using sprintf. Use single snprintf to count
15574 length of string rather than counting it via multiple sprintfs;
15575 that's simpler and more reliable.
15576 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15577 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15578 sprintf, in case result does not fit in int.
15580 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15581 (fontset_from_font): Print it.
15583 * frame.c (tty_frame_count): Now printmax_t, not int.
15584 (make_terminal_frame, set_term_frame_name): Print it.
15585 (x_report_frame_params): In X, window IDs are unsigned long,
15586 not signed long, so print them as unsigned.
15587 (validate_x_resource_name): Check for implausibly long names,
15588 and don't assume name length fits in 'int'.
15589 (x_get_resource_string): Don't blindly alloca invocation name;
15590 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15593 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15594 (xg_check_special_colors, xg_set_geometry):
15595 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15597 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15598 Use esprintf, not sprintf, in case result does not fit in int.
15600 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15601 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15602 it as a large positive number.
15603 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15604 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15606 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15607 in case result does not fit in int.
15609 * print.c (float_to_string): Detect width overflow more reliably.
15610 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15611 buffer overrun. Don't assume list length fits in 'int'. Treat
15612 print length of 0 as 0, not as infinity; to be consistent with other
15613 uses of print length in this function. Don't overflow print length
15614 index. Don't assume hash table size fits in 'long', or that
15615 vectorlike size fits in 'unsigned long'.
15617 * process.c (make_process): Use printmax_t, not int, to format
15618 process-name gensyms.
15620 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15622 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15623 to avoid potential buffer overrun.
15625 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15626 if X resource line is longer than 512 bytes.
15628 * xfns.c (x_window): Make sprintf buffer a bit bigger
15629 to avoid potential buffer overrun.
15631 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15633 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15635 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15637 Integer overflow fixes for scrolling, etc.
15638 Without these, Emacs silently mishandles large integers sometimes.
15639 For example, "C-u 4294967297 M-x recenter" was treated as if
15640 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15642 * xdisp.c (try_window_id): Check Emacs fixnum range before
15643 converting to 'int'.
15645 * window.c (window_scroll_line_based, Frecenter):
15646 Check that an Emacs fixnum is in range before assigning it to 'int'.
15647 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15648 values converted from Emacs fixnums.
15649 (Frecenter): Don't wrap around a line count if it is out of 'int'
15650 range; instead, treat it as an extreme value.
15651 (Fset_window_configuration, compare_window_configurations):
15652 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15654 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15655 that can exceed INT_MAX. Check that EMACS_INT value is in range
15656 before assigning it to the (possibly-narrower) index.
15657 (match_limit): Don't assume that a fixnum can fit in 'int'.
15659 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15662 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15663 (Fvertical_motion): Don't wrap around LINES values that don't fit
15664 in 'int'. Instead, treat them as extreme values. This is good
15665 enough for windows, which can't have more than INT_MAX lines anyway.
15667 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15669 * Require libxml/parser.h to avoid compilation warning.
15671 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15673 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15674 since this reportedly can destroy thread storage.
15676 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15678 * syntax.c (find_defun_start): Update all cache variables if
15679 exiting early (Bug#9401).
15681 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15683 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15685 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15686 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15687 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15689 * term.c (tty_append_glyph): New function.
15690 (produce_stretch_glyph): Static function and its prototype deleted.
15692 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15695 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15697 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15698 when checking :margin (Bug#9390).
15699 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15700 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15701 so that the name doesn't mislead. All uses changed.
15703 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15705 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15708 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15710 * xdisp.c (move_it_to): Don't bail out early when reaching
15711 position beyond to_charpos, if we are scanning backwards.
15712 (move_it_vertically_backward): When DY == 0, make sure we get to
15713 the first character in the line after the newline.
15715 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15717 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15718 (ccl_driver): Do not generate an out-of-range pointer.
15719 (Fccl_execute_on_string): Remove unnecessary check for
15720 integer overflow, noted by Stefan Monnier in
15721 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15722 Remove a FIXME that didn't need fixing.
15723 Simplify the newly-introduced buffer reallocation code.
15725 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15727 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15729 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15731 Integer and memory overflow issues (Bug#9196).
15733 * doc.c (get_doc_string): Rework so that
15734 get_doc_string_buffer_size is the actual buffer size, rather than
15735 being 1 less than the actual buffer size; this makes xpalloc more
15738 * image.c (x_allocate_bitmap_record, cache_image):
15739 * xselect.c (Fx_register_dnd_atom):
15740 Simplify previous changes by using xpalloc.
15742 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15743 since either will do and ptrdiff_t is convenient with xpalloc.
15745 * charset.c (charset_table_size)
15746 (struct charset_sort_data.priority): Now ptrdiff_t.
15747 (charset_compare): Don't overflow if priorities differ greatly.
15748 (Fsort_charsets): Don't assume list length fits in int.
15749 Check for size-calculation overflow when allocating sort data.
15750 (syms_of_charset): Allocate an initial charset table that is
15751 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15753 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15755 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15756 The actual value is always <= INT_MAX, and leaving it unsigned made
15757 overflow checking harder.
15759 * dispextern.h (struct glyph_matrix.rows_allocated)
15760 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15761 with xpalloc. The values are still always <= INT_MAX.
15763 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15765 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15766 (SAFE_NALLOCA): New macro.
15768 * region-cache.c (struct boundary.pos, find_cache_boundary)
15769 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15770 (set_cache_region, invalidate_region_cache)
15771 (revalidate_region_cache, know_region_cache, region_cache_forward)
15772 (region_cache_backward, pp_cache):
15773 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15774 so that ptrdiff_t * can be passed to xpalloc.
15775 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15776 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15777 (pp_cache): Don't assume cache_len fits in int.
15778 * region-cache.h: Adjust extern decls to match.
15780 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15781 EMACS_INT, since either will do, for xpalloc.
15783 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15784 (xnmalloc, xnrealloc, xpalloc): New functions.
15786 * bidi.c (bidi_shelve_header_size): New constant.
15787 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15788 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15790 * bidi.c (bidi_cache_shrink):
15791 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15793 Don't update size of array until after memory allocation succeeds,
15794 because xmalloc/xrealloc may not return.
15795 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15796 now that we have proper integer overflow checking.
15797 (record_overlay_string, overlay_strings): Catch overflows when
15798 calculating size of overlay_str_buf.
15800 * callproc.c (Fcall_process): Check for size overflow when
15801 calculating size of args2.
15802 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15803 Normally we prefer signed values, but sticking with ptrdiff_t would
15804 require adding more-complicated checks.
15806 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15807 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15808 Redo buffer-overflow calculations to avoid integer overflow.
15809 Add a FIXME comment where memory seems to be over-allocated.
15811 * character.c (Fstring): Check for size-calculation overflow.
15813 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15814 unnecessary integer overflow. Check for size overflow.
15815 (encode_coding_object): Don't update size until xmalloc succeeds.
15817 * composite.c (get_composition_id): Check for overflow in glyph
15818 length calculations.
15820 Integer and memory overflow fixes for display code.
15821 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15822 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15823 (scrolling_window): Check for overflow in size calculations.
15824 (line_draw_cost, realloc_glyph_pool, add_row_entry):
15825 Don't assume glyph table len fits in int.

15827 (row_table_size): Now ptrdiff_t, not int.
15828 (scrolling_window): Avoid overflow in size calculations.

15835 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15836 (get_doc_string): Check for size calculation overflow.
15837 Don't update size until allocation succeeds.
15838 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15839 EMACS_INT, where ptrdiff_t will do.
15840 (Fsubstitute_command_keys): Check for string overflow.
15842 * editfns.c (set_time_zone_rule): Don't assume environment length
15844 (message_length): Now ptrdiff_t, not int.
15845 (Fmessage_box): Don't update size until allocation succeeds.
15846 Don't assume message length fits in int.
15847 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15849 * emacs.c (main): Do not reallocate argv, since there is a null at
15850 the end that can be overwritten, and this way there's no need to
15851 worry about size-calculation overflow.
15852 (sort_args): Check for size-calculation overflow.
15854 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15856 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15858 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15859 (x_set_scroll_bar_width, x_figure_window_size):
15860 Check for integer overflow.
15861 (x_set_alpha): Do not assume XINT fits in int.
15863 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15864 This is for the members text_lines, text_cols, total_lines, total_cols,
15865 where the system imposes an 'int' limit.
15867 * fringe.c (Fdefine_fringe_bitmap):
15868 Don't update size until alloc works.
15870 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15871 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15873 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15874 Check for size-calculation overflow.
15875 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15876 do, as we prefer signed integers.
15877 (id_to_widget.max_size, id_to_widget.used)
15878 (xg_store_widget_in_map, xg_remove_widget_from_map)
15879 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15880 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15881 Use and return ptrdiff_t, not int.
15882 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15883 * gtkutil.h: Change prototypes to match the above.
15885 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15886 are duplicate now that they've been promoted to lisp.h.
15887 (x_allocate_bitmap_record, x_alloc_image_color)
15888 (make_image_cache, cache_image, xpm_load):
15889 Don't update size until alloc is done.
15890 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
15892 Check for size calculation overflow.
15893 (ct_colors_allocated_max): New constant.
15894 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid

15899 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15900 Use ptrdiff_t, not int, to count maps.
15901 (read_char_minibuf_menu_prompt): Check for overflow in size
15902 calculations. Don't update size until allocation succeeds.
15903 Redo calculations to avoid overflow.
15904 * keyboard.h: Change prototypes to match the above.
15906 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15908 (current_minor_maps): Check for size calculation overflow.
15909 * keymap.h: Change prototypes to match the above.
15911 * lread.c (read1, init_obarray): Don't update size until alloc done.
15913 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

15930 (Fset_match_data): Don't assume list lengths fit in 'int'.
15932 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15933 for command line length. Do not attempt to address one before the
15934 beginning of an array, as that's not portable.
15936 * term.c (max_frame_lines): Remove; unused.
15937 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15939 (encode_terminal_code, calculate_costs): Check for size
15940 calculation overflow.

15943 done. Redo calculations to avoid overflow.
15944 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
15946 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
15947 subtracting pointers.

15958 Use ptrdiff_t, not int, for sizes.
15959 (store_mode_line_noprop_char): Don't update size until alloc done.

15962 Use ptrdiff_t, not int, for sizes.
15963 (Finternal_make_lisp_face, cache_face):
15964 Check for size calculation overflow.
15965 (cache_face): Treat size calculation overflows as if they were
15966 memory exhaustion (the usual treatment), rather than aborting.
15968 * xfns.c (x_encode_text, x_set_name_internal)
15969 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15970 sizes, since they can exceed INT_MAX in size. Check for size
15971 calculation overflow.
15973 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
15974 (xg_select): Check for size calculation overflow.
15975 Don't update size until alloc done.
15977 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15978 as sprintf is limited to int lengths.
15980 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15981 (X_LONG_MIN): New macros.
15982 Use them to make the following changes clearer.
15983 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15984 This change doesn't affect the value now, but it may help remind
15985 future maintainers not to raise the value too much later.
15986 (SELECTION_QUANTUM): Remove, replacing with ...
15987 (selection_quantum): ... new function, which avoids overflow.
15989 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15990 assumption that selection length fits in 'int'.
15991 (x_reply_selection_request, x_handle_selection_request)
15992 (x_get_window_property, receive_incremental_selection)
15993 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
15994 (lisp_data_to_selection_data, clean_local_selection_data):

15996 (x_reply_selection_request, x_get_window_property)
15997 (receive_incremental_selection, x_property_data_to_lisp):
15998 Redo calculations to avoid overflow.
15999 (x_reply_selection_request): When sending hint, ceiling it at
16000 X_LONG_MAX rather than relying on wraparound overflow to send
16002 (x_get_window_property, receive_incremental_selection)
16003 (lisp_data_to_selection_data, x_property_data_to_lisp):
16004 Check for size-calculation overflow.
16005 (x_get_window_property, receive_incremental_selection)
16006 (lisp_data_to_selection_data, Fx_register_dnd_atom):
16007 Don't store size until memory allocation succeeds.
16008 (x_get_window_property): Plug memory leak on memory exhaustion.
16009 Don't double-block input; malloc is safe here. Don't assume 2**34
16010 - 4 fits in unsigned long. Add an xassert to check
16011 XGetWindowProperty overflow. Be more careful about overflow
16012 calculations, and distinguish size from memory overflow better.
16013 (receive_incremental_selection): When tracing, don't assume
16014 unsigned int is less than INT_MAX.
16015 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

16017 (lisp_data_to_selection_data): Don't assume that integers
16018 in the range -65535 through -1 fit in an X unsigned short.
16019 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16020 result parameters unless successful. Rely on cons_to_unsigned
16021 to report problems with elements; the old code wasn't right anyway.
16022 (x_check_property_data): Check for int overflow; we cannot use
16023 a wider type due to X limits.
16024 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

16029 (x_term_init): Check for size calculation overflow.
16030 (x_color_cells): Don't store size until memory allocation succeeds.
16031 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
16032 Don't assume alloca size is less than MAX_ALLOCA.
16033 (x_term_init): Don't assume length fits in int (sprintf is limited
16036 Use ptrdiff_t for composition IDs.
16037 * character.c (lisp_string_width):
16038 * composite.c (composition_table_size, n_compositions)
16039 (get_composition_id, composition_gstring_from_id):

16055 * image.c (xpm_get_color_table_h):
16056 * lisp.h (hash_lookup, hash_put):
16057 * minibuf.c (Ftest_completion):
16058 Use ptrdiff_t for hash table indexes, not int (which is too
16059 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16060 32-bit --with-wide-int hosts).
16062 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16063 Add a FIXME comment about memory leaks.
16064 (syms_of_charset): Don't assume xmalloc returns.
16066 Don't assume that stated character widths fit in int.

16068 * character.h (CHAR_WIDTH):
16069 * indent.c (MULTIBYTE_BYTES_WIDTH):
16070 Use sanitize_char_width to avoid undefined and/or bad behavior
16071 with outlandish widths.
16072 * character.h (sanitize_tab_width): Rename from sanitize_width,
16073 now that we have two such functions. All uses changed.

16085 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
16087 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
16088 Remove unreachable code.
16089 (read_hex, load_charset_map_from_file): Check for integer overflow.
16091 * xterm.c: Don't go over XClientMessageEvent limit.
16092 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16093 (x_send_scroll_bar_event): Likewise. Check that the size does not
16094 exceed limits imposed by XClientMessageEvent, as well as the usual
16095 ptrdiff_t and size_t limits.
16097 * keyboard.c: Overflow, signedness and related fixes.
16098 (make_lispy_movement): Use same integer type in forward decl
16099 that is used in the definition.
16100 (read_key_sequence, keyremap_step):
16101 Change bufsize argument back to int, undoing my 2011-03-30 change.
16102 We prefer signed types, and int is wide enough here.
16103 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16104 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16105 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16106 length, not size_t. Use ptrdiff_t for index, not int.
16107 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16108 possibility of integer overflow.
16110 Overflow, signedness and related fixes for images.

16120 * xdisp.c (calc_pixel_width_or_height):
16121 * xfns.c (image_cache_refcount):
16122 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
16123 on typical 64-bit hosts.

16131 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
16132 (lookup_image): Remove unnecessary tests.
16133 (xbm_image_p): Locals are now of int, not EMACS_INT,
16134 since parse_image_check makes sure they fit into int.
16135 (png_load, gif_load, svg_load_image):
16136 Prefer int to unsigned where either will do.
16137 (tiff_handler): New function, combining the cores of the
16138 old tiff_error_handler and tiff_warning_handler.
16139 This function is rewritten to use vsnprintf and thereby avoid
16140 stack buffer overflows. It uses only the features of vsnprintf
16141 that are common to both POSIX and native Microsoft.
16142 (tiff_error_handler, tiff_warning_handler): Use it.
16143 (tiff_load, gif_load, imagemagick_load_image):
16144 Don't assume :index value fits in 'int'.
16145 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16146 (imagemagick_load_image): Check that crop parameters fit into
16147 the integer types that MagickCropImage accepts. Don't assume
16148 Vimagemagick_render_type has a nonnegative value. Don't assume
16149 size_t fits in 'long'.
16150 (gs_load): Use printmax_t to print the widest integers possible.
16151 Check for integer overflow when computing image height and width.
16153 2011-08-26 Eli Zaretskii <eliz@gnu.org>
16155 * xdisp.c (redisplay_window): Don't force window start if point

16160 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
16161 the display spec is of the form `(space ...)'.
16162 (handle_display_spec): Return the value returned by
16163 handle_single_display_spec, not just 1 or zero.
16164 (handle_single_display_spec): If the display spec is of the form
16165 `(space ...)', and specifies display in the text area, return 2
16167 (try_cursor_movement): Check for the need to scroll more
16168 accurately, and prefer exact match for point under bidi.
16169 Don't advance `row' beyond the last row of the window.
16171 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
16172 into disp_prop; all users changed.
16174 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
16175 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
16176 for the text covered by the display property.

16186 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
16187 buffers, return left-to-right.
16188 (set_cursor_from_row): Consider candidate row a win if its glyph
16189 represents a newline and point is on that newline. Fixes cursor
16190 positioning on the newline at EOL of R2L text within L2R
16191 paragraph, and vice versa.
16192 (try_cursor_movement): Check continued rows, in addition to
16193 continuation rows. Fixes unwarranted scroll when point enters a
16194 continued line of R2L text within an L2R paragraph, or vice versa.
16195 (cursor_row_p): Consider the case of point being equal to
16196 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
16197 from the end of a short line to the beginning of a continued line
16198 of R2L text within L2R paragraph.
16199 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
16200 composed characters.

16215 2011-08-22 Kenichi Handa <handa@m17n.org>
16217 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
16218 extra slot even if the purpose is char-code-property-table.
16220 2011-08-23 Eli Zaretskii <eliz@gnu.org>
16222 * xdisp.c (redisplay_window): When computing centering_position,
16223 account for the height of the header line. (Bug#8874)
16225 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16226 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16227 candidate is selected by the mouse, and that candidate has a
16228 composed character under the mouse.
16230 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16231 coordinates reported by pos-visible-in-window-p for a composed
16232 character in column zero.
16234 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
16236 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
16238 2011-08-22 Eli Zaretskii <eliz@gnu.org>
16240 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
16241 consider it a hit if to_charpos is anywhere in the range of the
16242 composed buffer positions.
16244 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16246 * image.c (gif_load): Don't assume that each subimage has the same
16247 dimensions as the base image. Handle disposal method that is
16248 "undefined" by the gif spec (Bug#9335).
16250 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
16252 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
16253 (Fcondition_case): Document `debug' symbol in error handler.
16255 2011-08-19 Eli Zaretskii <eliz@gnu.org>
16257 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
16258 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
16259 from an Org mode buffer to a Speedbar frame.
16261 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
16262 a composition, take its buffer position from IT->cmp_it.charpos.
16263 Fixes cursor positioning at the beginning of a line that begins
16264 with a composed character.
16266 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16268 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16269 character bidirectional type, use STRONG_L instead. Fixes crashes
16270 in a buffer produced by `describe-categories'.
16272 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16273 members before the level stack, so they would be saved and
16274 restored when copying iterator state. Fixes incorrect reordering
16275 around TABs covered by display properties.
16277 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
16279 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

16284 (internal_condition_case_2, internal_condition_case_n):
16285 Remove unnecessary aborts (Bug#9081).
16287 2011-08-17 Eli Zaretskii <eliz@gnu.org>
16289 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
16290 has no `load' handler, try opening the file locally. (Bug#9311)
16292 2011-08-16 Ken Brown <kbrown@cornell.edu>
16294 * gmalloc.c: Expand comment.
16296 2011-08-16 Eli Zaretskii <eliz@gnu.org>
16298 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
16299 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
16301 2011-08-16 Ken Brown <kbrown@cornell.edu>
16303 Fix memory allocation problems in Cygwin build (Bug#9273).
16305 * unexcw.c ( __malloc_initialized): Declare external variable.
16306 (fixup_executable): Force the dumped emacs to reinitialize malloc.
16308 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
16310 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

16338 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
16339 coordinates of the iterator when restoring from ppos_it.
16342 2011-08-14 Kenichi Handa <handa@m17n.org>
16344 * process.c (create_process): Call setup_process_coding_systems
16345 after the pid of the process is set to -1 (Bug#8162).
16347 2011-08-14 Eli Zaretskii <eliz@gnu.org>
16349 * xdisp.c (move_it_in_display_line_to): Don't invoke
16350 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16351 ppos_it. Fixes vertical cursor motion when line beginning is
16352 covered by an image. (Bug#9296)
16354 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
16356 * nsterm.h (ns_run_ascript): Declare.

16359 * nsfns.m (as_script, as_result, as_status): New static variables.
16360 (ns_run_ascript): New function.
16361 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
16362 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
16363 the event loop. Get status from as_status (Bug#7276).
16365 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16366 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16367 the event loop (Bug#7276).
16369 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
16371 * gnutls.c (QCgnutls_bootprop_priority)

16392 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
16393 (Fnetwork_interface_list): Allocate in increments of bytes instead
16394 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16395 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16397 (struct ifflag_def): notrailers is smart on OSX.
16398 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16399 Get hardware address with getifaddrs if available.
16401 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16403 * xdisp.c (iterate_out_of_display_property): xassert that
16404 IT->position is set to within IT->object's boundaries. Break from
16405 the loop as soon as EOB is reached; avoids infloops in redisplay
16406 when IT->position is set up wrongly due to some bug.
16407 Set IT->current to match the bidi iterator unconditionally.
16408 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16409 entry. Force push_it to save on the stack the current
16410 buffer/string position, to be restored by pop_it. Fix flags in
16411 the iterator structure wrt the object coming from a display
16412 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16413 properties. (Bug#9284)
16415 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16417 * fontset.c (fontset_get_font_group): Add proper type checks.

16423 and LC_VERSION_MIN_MACOSX.
16424 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
16425 (dump_it) [LC_FUNCTION_STARTS]: Use it.
16427 2011-08-08 Eli Zaretskii <eliz@gnu.org>
16429 * xdisp.c (forward_to_next_line_start): Allow to use the
16430 no-display-properties-and-no-overlays under bidi display.
16431 Set disp_pos in the bidi iterator to avoid searches for display
16432 properties and overlays.
16434 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16436 * editfns.c (Fset_time_zone_rule): Document relationship with the
16439 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
16440 the font entity extracted from the cache (Bug#8109).
16442 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
16444 * composite.c (autocmp_chars): Don't reset point. That is done by
16445 restore_point_unwind (Bug#5984).
16447 2011-08-07 Juri Linkov <juri@jurta.org>
16449 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16450 to show the arg `TIME' instead of `TIMEVAL'.
16452 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16454 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16455 display property strides EOL and includes a newline, as in
16456 longlines-mode. (Bug#9254)
16457 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16458 word-wrap under bidirectional display. (Bug#9224)
16460 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16461 is non-zero, even if the data buffer is NULL. Fixes a crash in
16462 vertical-motion with longlines-mode. (Bug#9254)
16464 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16466 * bidi.c <bidi_cache_total_alloc>: Now static.
16467 (bidi_initialize): Initialize bidi_cache_total_alloc.
16469 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16472 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16473 amount allocated this far in `bidi_cache_total_alloc'.
16474 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16475 non-zero, only free the data buffer without restoring the cache
16476 contents. All callers changed.
16478 * dispextern.h (bidi_unshelve_cache): Update prototype.
16480 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16481 (move_it_in_display_line, move_it_to)
16482 (move_it_vertically_backward, move_it_by_lines): Replace the call
16483 to xfree to an equivalent call to bidi_unshelve_cache.
16484 (move_it_in_display_line_to): Fix logic of returning
16485 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16487 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16489 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16490 came from a string character with a `cursor' property. (Bug#9229)
16492 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16494 * Makefile.in (LIB_PTHREAD): New variable.
16495 (LIBES): Add LIB_PTHREAD (Bug#9216).
16497 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
16498 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
16500 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
16502 * regex.c (re_iswctype): Remove some redundant boolean conversions.
16504 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16506 * xterm.c (x_find_topmost_parent): New function.
16507 (x_set_frame_alpha): Find topmost parent window with
16508 x_find_topmost_parent and set the property there also (bug#9181).
16509 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16511 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16513 * callproc.c (Fcall_process): Avoid vfork clobbering
16514 the local vars buffer, coding_systems, current_dir.
16516 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
16518 * keymap.c (Fmake_composed_keymap): Move to subr.el.
16520 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
16522 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16523 so that it is not optimized away.
16525 * xdisp.c (compute_display_string_pos): Remove unused local.
16527 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16529 Fix slow cursor motion and scrolling in large buffers with
16530 selective display, like Org Mode buffers. (Bug#9218)
16532 * dispextern.h (struct bidi_it): New member disp_prop_p.
16534 * xdisp.c: Remove one-slot cache of display string positions.
16535 (compute_display_string_pos): Accept an additional argument
16536 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16537 for a display string or property. If found, set DISP_PROP_P
16540 * bidi.c (bidi_fetch_char): Accept an additional argument
16541 DISP_PROP_P, and pass it to compute_display_string_pos.
16542 Only handle text covered by a display string if DISP_PROP_P is returned
16543 non-zero. All callers of bidi_fetch_char changed.
16545 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16547 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16549 2010-12-03 Don March <don@ohspite.net>
16551 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16552 last character M-[char] is translated to ESC [char] (bug#7541).
16554 2011-08-02 Kenichi Handa <handa@m17n.org>
16556 * lisp.h (uniprop_table): Extern it.
16558 * chartab.c (uniprop_table): Make it non-static.
16560 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16562 * xdisp.c (forward_to_next_line_start): Accept additional argument
16563 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16565 (reseat_at_next_visible_line_start): Use the bidi iterator state
16566 returned by forward_to_next_line_start to restore the state of
16567 it->bidi_it after backing up to previous newline. (Bug#9212)
16569 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16571 * regex.c (re_comp): Protoize.
16572 (re_exec): Fix return type.
16573 (regexec): Fix type of `ret'. (Bug#9203)
16575 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16577 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16578 This is needed if max-image-size is a floating-point number.
16580 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16582 * print.c (print_object): Print empty symbol as ##.
16584 * lread.c (read1): Read ## as empty symbol.
16586 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16588 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16589 setting frame foreground color (Bug#9175).
16590 (x_set_background_color): Likewise.
16592 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16593 contents (Bug#9176).
16594 (EmacsTooltip -init): Remove bezels and add shadows to
16597 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16598 or scroll bar (Bug#8470).
16600 * nsfont.m (nsfont_open): Remove assignment to voffset and
16601 unnecessary vars hshink, expand, hd, full_height, min_height.
16602 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16604 * nsterm.h (nsfont_info): Remove voffset field.
16606 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16608 Implement strike-through and overline on NextStep (Bug#8863).
16610 * nsfont.m (nsfont_open): Use underline position provided by font,
16611 instead of hard-coded value of 2.
16612 (nsfont_draw): Call ns_draw_text_decoration instead.
16614 * nsterm.h: Add declaration for ns_draw_text_decoration.
16616 * nsterm.m (ns_draw_text_decoration): New function for drawing
16617 underline, overline, and strike-through.
16618 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16619 ns_draw_text_decoration. Change treatment of cursor drawing to
16620 accommodate underlining, etc.
16622 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16624 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16627 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16629 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16630 Without this fix, if a signal arrives just after memory fills up,
16631 'malloc' might be invoked reentrantly.
16633 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16634 In other words, assume that every image size is allowed, on non-X
16635 hosts. This assumption is probably wrong, but it lets Emacs compile.
16637 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16639 * regex.c (re_iswctype): Convert return values to boolean.
16641 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16643 * xdisp.c (compute_display_string_pos): Don't use cached display
16644 string position if the buffer had its restriction changed.
16647 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16649 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16651 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16653 Integer signedness and overflow and related fixes. (Bug#9079)
16655 * bidi.c: Integer size and overflow fixes.
16656 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16657 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16658 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16659 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16660 (bidi_find_other_level_edge):
16661 Use ptrdiff_t instead of EMACS_INT where either will do.
16662 This works better on 32-bit hosts configured --with-wide-int.
16663 (bidi_cache_ensure_space): Check for size-calculation overflow.
16664 Use % rather than repeated addition, for better worst-case speed.
16665 Don't set bidi_cache_size until after xrealloc returns, because it
16667 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16668 (bidi_cache_ensure_space): Also check that the bidi cache size
16669 does not exceed that of the largest Lisp string or buffer. See Eli
16670 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16672 * alloc.c (__malloc_size_t): Remove.
16673 All uses replaced by size_t. See Andreas Schwab's note
16674 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16676 * image.c: Improve checking for integer overflow.
16677 (check_image_size): Assume that f is nonnull, since
16678 it is always nonnull in practice. This is one less thing to
16679 worry about when checking for integer overflow later.
16680 (x_check_image_size): New function, which checks for integer
16681 overflow issues inside X.
16682 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16683 This removes the need for a memory_full check.
16684 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16685 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16686 (xbm_read_bitmap_data): Change locals back to 'int', since
16687 their values must fit in 'int'.
16688 (xpm_load_image, png_load, tiff_load):
16689 Invoke x_create_x_image_and_pixmap earlier,
16690 to avoid much needless work if the image is too large.
16691 (tiff_load): Treat overly large images as if
16692 x_create_x_image_and_pixmap failed, not as malloc failures.
16693 (gs_load): Use x_check_image_size.
16695 * gtkutil.c: Omit integer casts.
16696 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16697 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16699 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16701 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16702 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16703 would wrongly return t on a 64-bit host.
16705 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16706 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16707 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16708 and therefore cause GCC to emit a bogus diagnostic in some cases.
16710 * image.c: Integer signedness and overflow and related fixes.
16711 This is not an exhaustive set of fixes, but it's time to
16712 record what I've got.
16713 (lookup_pixel_color, check_image_size): Remove redundant decls.
16714 (check_image_size): Don't assume that arbitrary EMACS_INT values
16715 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16716 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16717 (tiff_load, imagemagick_load_image):
16718 Check for overflow in size calculations.
16719 (x_create_x_image_and_pixmap): Remove unnecessary test for
16720 xmalloc returning NULL; that can't happen.
16721 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16722 (xpm_color_bucket): Use better integer hashing function.
16723 (xpm_cache_color): Don't possibly over-allocate memory.
16724 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16725 (gif_memory_source):
16726 Use ptrdiff_t, not int or size_t, to record sizes.
16727 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16728 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16729 either works, as we prefer signed integers.
16730 (tiff_read_from_memory, tiff_write_from_memory):
16731 Return tsize_t, not size_t, since that's what the TIFF API wants.
16732 (tiff_read_from_memory): Don't fail simply because the read would
16733 go past EOF; instead, return a short read.
16734 (tiff_load): Omit no-longer-needed casts.
16735 (Fimagemagick_types): Don't assume size fits into 'int'.
16737 Improve hashing quality when configured --with-wide-int.
16738 * fns.c (hash_string): New function, taken from sxhash_string.
16739 Do not discard information about ASCII character case; this
16740 discarding is no longer needed.
16741 (sxhash-string): Use it. Change sig to match it. Caller changed.
16742 * lisp.h: Declare it.
16743 * lread.c (hash_string): Remove, since we now use fns.c's version.
16744 The fns.c version returns a wider integer if --with-wide-int is
16745 specified, so this should help the quality of the hashing a bit.
16747 * emacs.c: Integer overflow minor fix.
16748 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16749 Define only if GNU_LINUX.
16750 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16752 * dispnew.c: Integer signedness and overflow fixes.
16753 Remove unnecessary forward decls, that were a maintenance hassle.
16754 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16756 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16757 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16758 (prepare_desired_row, line_draw_cost):
16759 Use int, not unsigned, where either works.
16760 (save_current_matrix, restore_current_matrix):
16761 Use ptrdiff_t, not size_t, where either works.
16762 (init_display): Check for overflow more accurately, and without
16763 relying on undefined behavior.
16765 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16766 Remove, replacing with the new symbols in lisp.h. All uses changed.
16767 * fileio.c (make_temp_name):
16768 * filelock.c (lock_file_1, lock_file):
16769 * xdisp.c (message_dolog):
16770 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16771 Use pMd etc. instead.
16772 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16773 replacing the pWIDE etc. symbols removed from editfns.c.
16775 * keyboard.h (num_input_events): Now uintmax_t.
16776 This is (very slightly) less likely to mess up due to wraparound.
16779 * buffer.c: Integer signedness fixes.
16780 (alloc_buffer_text, enlarge_buffer_text):
16781 Use ptrdiff_t rather than size_t when either will do, as we prefer
16784 * alloc.c: Integer signedness and overflow fixes.
16785 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16786 (__malloc_size_t): Default to size_t, not to int.
16787 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16788 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16789 Prefer ptrdiff_t to size_t when either would do, as we prefer
16791 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16792 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16793 Now const. Initialize with values that are in range even if char
16795 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16796 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16797 These functions do the right thing with sizes > 2**32.
16798 (check_depth): Now ptrdiff_t, not int.
16799 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16800 Adjust to new way of storing sizes. Check for size overflow bugs
16802 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16803 slightly wrong anyway, as it missed one instance of
16804 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16805 (refill_memory_reserve): Omit needless cast to size_t.
16806 (mark_object_loop_halt): Mark as externally visible.
16808 * xselect.c: Integer signedness and overflow fixes.
16809 (Fx_register_dnd_atom, x_handle_dnd_message):
16810 Use ptrdiff_t, not size_t, since we prefer signed.
16811 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16812 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16813 x_dnd_atoms_size and x_dnd_atoms_length.
16815 * doprnt.c: Prefer signed to unsigned when either works.
16817 * doprnt.c (doprnt):
16819 * xdisp.c (vmessage):
16820 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16821 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16822 prefer signed arithmetic to avoid comparison confusion.
16823 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16824 but is a bit tricky.
16826 Assume freestanding C89 headers, string.h, stdlib.h.
16827 * data.c, doprnt.c, floatfns.c, print.c:
16828 Include float.h unconditionally.
16829 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16830 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16831 * regex.c: Likewise for stddef.h, string.h.
16832 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16833 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16834 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16835 (STDC_HEADERS): Remove obsolete defines.
16836 * sysdep.c: Include limits.h unconditionally.
16838 Assume support for memcmp, memcpy, memmove, memset.
16839 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16840 * regex.c (memcmp, memcpy):
16841 Remove; we assume C89 now.
16843 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16844 (__malloc_safe_bcopy): Remove; no longer needed.
16846 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16847 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16848 well either way, and we prefer signed to unsigned.
16850 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16852 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16853 closes the connection while we're reading (bug#9182).
16855 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16857 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16858 are specified (Bug#9168).
16860 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16862 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16863 Found by GCC static checking and --with-wide-int on a 32-bit host.
16865 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16867 * xdisp.c (compute_display_string_pos): Fix logic of caching
16868 previous display string position. Initialize cached_prev_pos to
16869 -1. Fixes slow-down at the beginning of a buffer.
16871 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16873 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16874 for attrs[LFACE_FONTSET_INDEX].
16876 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16878 * xml.c (parse_region): Remove unused local
16879 that was recently introduced.
16881 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16883 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16884 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16886 * xdisp.c (move_it_in_display_line_to): Record the best matching
16887 position for TO_CHARPOS while scanning the line, and restore it on
16888 exit if none of the characters scanned was an exact match.
16889 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16890 when exact match is impossible due to invisible text, and the
16891 lines are truncated.
16893 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16895 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16898 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16900 Fix a significant slow-down of cursor motion with C-n, C-p,
16901 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16902 auto-repeat under bidi redisplay in fontified buffers.
16903 * xdisp.c (compute_stop_pos_backwards): New function.
16904 (next_element_from_buffer): Call compute_stop_pos_backwards to
16905 find a suitable prev_stop when we find ourselves before
16907 (reseat): Don't look for prev_stop, as that could mean a very long
16909 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16910 <cached_disp_overlay_modiff>: Cache for last found display string
16912 (compute_display_string_pos): Return the cached position if asked
16913 about the same buffer in the same area of character positions, and
16914 the buffer wasn't changed since the time the display string
16915 position was cached.
16917 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16919 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16920 is an integer, which is important for empty lines. (Bug#9149)
16922 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16924 * frame.c (Fmodify_frame_parameters): In tty case, update the
16925 default face if necessary (Bug#4238).
16927 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16929 * editfns.c (Fstring_to_char): No need to explain what a character
16930 is in the docstring (Bug#6576).
16932 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16934 * xml.c (parse_region): Make sure we always return a tree.
16936 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16938 * xml.c (parse_region): If a document contains only comments,
16941 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16943 * xml.c (make_dom): Return comments, too.
16945 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16948 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16949 and the surrounding thread.
16950 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16951 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16952 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16954 * s/openbsd.h (BROKEN_SIGIO): Define.
16955 * unexelf.c (unexec) [__OpenBSD__]:
16956 Don't update the .mdebug section of the Alpha COFF symbol table.
16958 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16960 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16963 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16965 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16966 This fixes some race conditions on the permissions of any newly
16969 * alloc.c (valid_pointer_p): Use pipe, not open.
16970 This fixes some permissions issues when debugging.
16972 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16973 If fchown fails to set both uid and gid, try to set just gid,
16974 as that is sometimes allowed. Adjust the file's mode to eliminate
16975 setuid or setgid bits that are inappropriate if fchown fails.
16977 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16979 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

16985 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16987 * lread.c (read_integer): Unread even EOF character.
16988 (read1): Likewise. Properly record start position of symbol.

16991 symbol character follows.
16993 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16995 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16996 This works around a problem with the previous change to Fcopy_file.
16997 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16998 and without this change, GCC might complain about discarding
16999 fchown's return value.
17001 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17003 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17005 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17007 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17009 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17011 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17012 it's used from the C level.
17014 * process.c: Use the same condition for POLL_FOR_INPUT in both
17015 keyboard.c and process.c (bug#1858).
17017 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17019 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17020 (Fgnutls_boot): Use it.
17022 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17024 * doc.c (Fsubstitute_command_keys): Revert last change.
17026 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17028 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17029 quotes the next character, and doesn't affect other longer
17030 sequences (bug#8935).
17032 * lread.c (syms_of_lread): Clarify that is isn't only
17033 `eval-buffer' and `eval-defun' that's affected by
17034 `lexical-binding' (bug#8460).
17036 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17038 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17039 bidi redisplay when a line includes both an image and is truncated.
17041 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17043 Fix minor problems found by static checking.
17044 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17045 (elsz): Now a signed constant, not a size_t var. We prefer signed
17046 types to unsigned, to avoid integer comparison confusion. Without
17047 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17048 "cannot optimize loop, the loop counter may overflow", a symptom
17050 * indent.c (Fvertical_motion): Mark locals as initialized.
17051 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17053 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
17055 * search.c (Fre_search_backward): Mention `case-fold-search' in
17056 all the re_search_* functions (bug#8138).

17076 buffer position was specified. Initialize paragraph_embedding to
17078 (reseat_to_string): Initialize the bidi iterator.
17079 (display_string): If we need to ignore text properties of
17080 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17081 original value of -1 will not work with bidi.)
17082 (compute_display_string_pos): First arg is now struct
17083 `text_pos *'; all callers changed. Support display properties on
17085 (compute_display_string_end): Support display properties on Lisp
17087 (init_iterator, reseat_1, reseat_to_string): Initialize the
17088 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
17089 when iterating on a string not from display properties).
17090 (compute_display_string_pos, compute_display_string_end):
17091 Fix calculation of the object to scan. Fixes an error when using
17093 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
17094 base_level_stop; instead, set base_level_stop to BEGV.
17095 Fixes crashes in vertical-motion.
17096 (next_element_from_buffer): Improve commentary for when
17097 the iterator is before prev_stop.
17098 (init_iterator): Initialize bidi_p from the default value of
17099 bidi-display-reordering, not from buffer-local value. Use the
17100 buffer-local value only if initializing for buffer iteration.
17101 (handle_invisible_prop): Support invisible properties on strings
17102 that are being bidi-reordered.

17121 parts of next_element_from_buffer, next_element_from_string, and
17122 next_element_from_c_string.
17123 (tool_bar_lines_needed, redisplay_tool_bar)
17124 (display_menu_bar): Force left-to-right direction. Add a FIXME
17125 comment for making that be controlled by a user option.

17134 (get_overlay_strings_1, push_display_prop): Set up the bidi
17135 iterator for displaying display or overlay strings.
17136 (forward_to_next_line_start): Don't use the shortcut if
17138 (back_to_previous_visible_line_start): If handle_display_prop
17139 pushed the iterator stack, restore the internal state of the bidi
17140 iterator by calling bidi_pop_it same number of times.
17141 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
17142 and we are bidi-iterating, don't decrement the iterator position;
17143 instead, set the first_elt flag in the bidi iterator, to produce
17145 (reseat_1): Remove redundant setting of string_from_display_prop_p.
17146 (push_display_prop): xassert that we are iterating a buffer.
17147 (push_it, pop_it): Save and restore paragraph_embedding member.
17148 (handle_single_display_spec, next_overlay_string)
17149 (get_overlay_strings_1, reseat_1, reseat_to_string)
17150 (push_display_prop): Set up the `unibyte' member of bidi_it.string
17151 correctly. Don't assume unibyte strings are not bidi-reordered.

17159 popping after iteration over a string that came from a display
17160 property. Fix a typo in popping stretch info. Add an assertion
17161 for verifying that the iterator position is in sync with the bidi
17163 (handle_single_display_spec, get_overlay_strings_1)

17188 displayed in margins. (Bug#8133) (Bug#8867)
17189 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past

17253 (struct iterator_stack_entry): New members bidi_p,
17254 paragraph_embedding, and from_disp_prop_p.

17305 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
17307 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
17308 The old code sometimes used this field without initializing it.
17310 * alloc.c (gc_sweep): Don't read past end of array.
17311 In theory, the old code could also have corrupted Emacs internals,
17312 though it'd be very unlikely.

17316 * character.c (Fcharacterp): Don't advertise optional ignored
17317 argument. (Bug#4026)

17575 (clone_per_buffer_values): Don't assume that

17577 This isn't true in general, and it's particularly not true
17578 if Emacs is configured with --with-wide-int.
17579 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
17580 New macros, used in the buffer.c change.

17616 Random fixes. E.g., (random) never returned negative values.
17617 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17618 subseconds part to the entropy, as that's a bit more random.
17619 Prefer signed to unsigned, since the signedness doesn't matter and
17620 in general we prefer signed. When given a limit, use a
17621 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17622 latter isn't right if USE_2_TAGS_FOR_INTS.
17623 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17624 not 0..VALMASK. Don't discard "excess" bits that random () returns.
17626 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
17628 * textprop.c (text_property_stickiness):
17629 Obey Vtext_property_default_nonsticky.

17636 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
17637 This is more efficient than Ffile_directory_p and avoids a minor race.
17639 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
17641 * buffer.c (Foverlay_put): Say what the return value is
17644 * fileio.c (barf_or_query_if_file_exists): Check first if the file
17645 is a directory before asking whether to use the file name
17647 (barf_or_query_if_file_exists): Make the "File is a directory"
17648 error be more correct.
17650 * fns.c (Frequire): Remove the mention of the .gz files, since
17651 that's installation-specific, but keep the mention of
17652 `get-load-suffixes'.
17654 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
17656 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

17664 Qgnutls_bootprop_verify_error (which is no longer used).
17666 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
17667 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17668 Also (re)move comments that are misplaced or no longer relevant.
17670 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
17672 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

17693 leave any prefix arg for the up event (Bug#1586).
17695 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
17697 * lread.c (syms_of_lread): Mention single symbols defined by
17698 `defvar' or `defconst' (bug#7154).
17700 * fns.c (Frequire): Mention .el.gz files (bug#7314).
17701 (Frequire): Mention get-load-suffixes.

17729 minibuffer-local-must-match-map, and
17730 minibuffer-local-filename-must-match-map to Elisp.
17731 (syms_of_keymap): Defsubr make-composed-keymap.
17732 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

17761 (xgselect_initialize): Ditto.
17763 * process.c: Add defined (HAVE_GSETTINGS) for xgselect.h

17767 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
17769 * eval.c (struct backtrace): Simplify and port the data structure.
17770 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17771 signed bit field, as this assumption is not portable and it makes
17772 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17773 "char debug_on_exit : 1" as this is not portable either; instead,
17774 use the portable "unsigned int debug_on_exit : 1". Remove unused
17775 member evalargs. Remove obsolete comments about cc bombing out.
17777 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

17943 * print.c (printchar, strout): Check for string overflow.
17944 (PRINTPREPARE, printchar, strout):
17945 Don't set size unless allocation succeeds.
17947 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17948 for sizes. Check for string overflow more accurately.

17952 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17953 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

17959 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17961 * lread.c: Integer overflow fixes.
17962 (read_integer): Radix is now EMACS_INT, not int,
17963 to improve quality of diagnostics for out-of-range radices.
17964 Calculate buffer size correctly for out-of-range radices.
17965 (read1): Check for integer overflow in radices, and in
17966 read-circle numbers.
17967 (read_escape): Avoid int overflow.
17968 (Fload, openp, read_buffer_size, read1)
17969 (substitute_object_recurse, read_vector, read_list, map_obarray):

17985 2011-06-22 Leo Liu <sdl.web@gmail.com>
17987 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17988 Move to minibuffer.el.
17990 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17992 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17993 The following patches are for when GLYPH_DEBUG && !XASSERT.
17994 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17995 * dispnew.c (flush_stdout):
17996 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17997 Mark as externally visible.
17998 * dispnew.c (check_window_matrix_pointers): Now static.
17999 * dispnew.c (window_to_frame_vpos):
18000 * xfns.c (unwind_create_frame):
18001 * xterm.c (x_check_font): Remove unused local.
18002 * scroll.c (CHECK_BOUNDS):
18003 * xfaces.c (cache_fache): Rename local to avoid shadowing.
18004 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
18005 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
18006 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
18007 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
18009 (debug_method_add): Use va_list and vsprintf rather than relying
18010 on undefined behavior with wrong number of arguments.
18011 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18012 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18013 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18014 since we're not interested in debugging glyphs with old libraries.
18015 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18016 GCC 4.6.0's static checking.
18018 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18020 Integer overflow and signedness fixes (Bug#8873).

18036 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
18037 (.bitmaps_last, struct x_output.icon_bitmap):
18038 Use ptrdiff_t, not int, for bitmap indexes.
18039 (x_allocate_bitmap_record): Check for size overflow.
18040 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
18042 Use ptrdiff_t, not int, for overlay counts.
18043 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
18044 * editfns.c (overlays_around, get_pos_property):
18045 * textprop.c (get_char_property_and_overlay):
18046 * xdisp.c (next_overlay_change, note_mouse_highlight):
18047 * xfaces.c (face_at_buffer_position):
18048 * buffer.c (OVERLAY_COUNT_MAX): New macro.
18049 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
18050 (Fnext_overlay_change, Fprevious_overlay_change)
18051 (mouse_face_overlay_overlaps, Foverlays_in):
18052 Use ptrdiff_t, not int, for sizes.
18053 (overlays_at, overlays_in): Check for size-calculation overflow.
18055 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18057 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18058 (x_session_initialize): Do not assume string length fits in int.
18060 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18061 This is unlikely, but can occur if DPI is outlandish.
18063 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
18064 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
18066 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
18067 * xrdb.c (magic_file_p, search_magic_path):
18068 Omit last arg SUFFIX; it was always 0. All callers changed.
18069 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18071 * xfont.c (xfont_match): Avoid need for strlen.
18073 * xfns.c: Don't assume strlen fits in int.

18076 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18077 not unsigned long, as we prefer signed integers. All callers changed.
18078 Detect integer overflow in repeat count.
18079 (message_dolog): Don't assume print length fits in 39 bytes.
18080 (display_mode_element): Don't assume strlen fits in int.
18082 * termcap.c: Don't assume sizes fit in int and never overflow.
18083 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
18084 (gobble_line): Check for size-calculation overflow.
18086 * minibuf.c (Fread_buffer):
18087 * lread.c (intern, intern_c_string):
18088 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

18101 * filelock.c: Fix some buffer overrun and integer overflow issues.
18102 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18103 Reformulate so as not to need the command string.
18104 Invoke gzip -cd rather than gunzip, as it's more portable.
18105 (lock_info_type, lock_file_1, lock_file):
18106 Don't assume pid_t and time_t fit in unsigned long.
18107 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18108 (current_lock_owner): Prefer signed type for sizes.
18109 Use memcpy, not strncpy, where memcpy is what is really wanted.
18110 Don't assume (via atoi) that time_t and pid_t fit in int.
18111 Check for time_t and/or pid_t out of range, e.g., via a network share.
18112 Don't alloca where an auto var works fine.
18114 * fileio.c: Fix some integer overflow issues.
18115 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18116 Don't assume string length fits in int.
18117 (directory_file_name): Don't assume string length fits in long.
18118 (make_temp_name): Don't assume pid fits in int, or that its print
18119 length is less than 20.
18121 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
18123 * coding.c (make_subsidiaries): Don't assume string length fits in int.
18125 * callproc.c (child_setup): Rewrite to avoid two strlen calls.

18138 (Fgetenv_internal):
18139 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18141 * lread.c (invalid_syntax): Omit length argument.
18142 All uses changed. This doesn't fix a bug, but it simplifies the
18143 code away from its former Hollerith-constant appearance, and it's
18144 one less 'int' to worry about when looking at integer-overflow issues.
18145 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18147 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18148 This didn't break anything, but it didn't help either.
18149 It's confusing to put a bogus integer in a place where the actual
18150 value does not matter.
18151 (LIST_END_P): Remove unused macro and its bogus comment.
18152 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18154 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18155 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18157 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18158 We prefer signed types, and the value cannot exceed the EMACS_INT
18159 range anyway (because otherwise the length would not be representable).
18160 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18161 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18162 This avoids a GCC warning when WIDE_EMACS_INT.
18164 * indent.c (sane_tab_width): New function.
18165 (current_column, scan_for_column, Findent_to, position_indentation)
18166 (compute_motion): Use it. This is just for clarity.
18167 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18169 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
18171 * lisp.h (lint_assume): New macro.
18172 * composite.c (composition_gstring_put_cache):
18173 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18175 * editfns.c, insdel.c:
18176 Omit unnecessary forward decls, to simplify future changes.
18178 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18180 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18182 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18183 Use much-faster test for byte-length change.
18184 Don't assume string byte-length fits in 'int'.
18185 Check that character arg fits in 'int'.
18186 (mapcar1): Declare byte as byte, for clarity.
18188 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18190 * fns.c (concat): Catch string overflow earlier.
18191 Do not rely on integer wraparound.
18193 * dispextern.h (struct it.overlay_strings_charpos)
18194 (struct it.selective): Now EMACS_INT, not int.
18195 * xdisp.c (forward_to_next_line_start)
18196 (back_to_previous_visible_line_start)
18197 (reseat_at_next_visible_line_start, next_element_from_buffer):
18198 Don't arbitrarily truncate the value of 'selective' to int.
18200 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18202 * composite.c: Don't truncate sizes to 'int'.
18203 (composition_gstring_p, composition_reseat_it)
18204 (composition_adjust_point): Use EMACS_INT, not int.
18205 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18206 not EMACS_UINT, for indexes.
18208 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18210 * buffer.c: Include <verify.h>.
18211 (struct sortvec.priority, struct sortstr.priority):
18212 Now EMACS_INT, not int.
18213 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18214 (struct sortstr.size, record_overlay_string)
18215 (struct sortstrlist.size, struct sortlist.used):
18216 Don't truncate size to int.
18217 (record_overlay_string): Check for size-calculation overflow.
18218 (init_buffer_once): Check at compile-time, not run-time.
18220 2011-06-22 Jim Meyering <meyering@redhat.com>
18222 Don't leak an XBM-image-sized buffer
18223 * image.c (xbm_load): Free the image buffer after using it.
18225 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18228 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18229 that Sun C diagnosed.
18230 * fns.c (secure_hash): Fix pointer signedness issue.
18231 * intervals.c (static_offset_intervals): New function.
18232 (offset_intervals): Use it.
18234 2011-06-21 Leo Liu <sdl.web@gmail.com>
18237 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18240 * fns.c (secure_hash): Rename from crypto_hash_function and change
18241 the first arg to accept symbols.
18242 (Fsecure_hash): New primitive.
18243 (syms_of_fns): New symbols.
18245 2011-06-20 Deniz Dogan <deniz@dogan.se>
18247 * process.c (Fset_process_buffer): Clarify return value in
18250 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18252 * dispnew.c (add_window_display_history): Use BVAR.
18254 * xdisp.c (debug_method_add): Use BVAR.
18255 (check_window_end, dump_glyph_matrix, dump_glyph)
18256 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18258 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18261 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18262 check till after the cache is created in init_frame_faces.
18264 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18266 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18268 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18270 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18271 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18272 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18274 Improve buffer-overflow checking (Bug#8873).
18275 * fileio.c (Finsert_file_contents):
18276 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18277 Remove the old (too-loose) buffer overflow checks.
18278 They weren't needed, since make_gap checks for buffer overflow.
18279 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18280 The old code merely checked for Emacs fixnum overflow, and relied
18281 on undefined (wraparound) behavior. The new code avoids undefined
18282 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18284 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18285 Tune. Don't use wider integers than needed. Don't use alloca.
18286 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18288 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18290 * insdel.c, lisp.h (buffer_overflow): New function.
18291 (insert_from_buffer_1, replace_range, replace_range_2):
18292 * insdel.c (make_gap_larger):
18293 * editfns.c (Finsert_char):
18294 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18296 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18298 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18300 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18302 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18303 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18305 * fileio.c: Don't assume EMACS_INT fits in off_t.
18306 (emacs_lseek): New static function.
18307 (Finsert_file_contents, Fwrite_region): Use it.
18308 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18310 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18312 * fns.c: Don't overflow int when computing a list length.
18313 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18314 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18315 truncation on 64-bit hosts. Check for QUIT every
18316 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18317 faster and is responsive enough.
18318 (Flength): Report an error instead of overflowing an integer.
18319 (Fsafe_length): Return a float if the value is not representable
18320 as a fixnum. This shouldn't happen except in contrived situations.
18321 (Fnthcdr, Fsort): Don't assume list length fits in int.
18322 (Fcopy_sequence): Don't assume vector length fits in int.
18324 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18325 (header_size, word_size): New constants.
18326 (allocate_vectorlike): Don't check size overflow here.
18327 (allocate_vector): Check it here instead, since this is the only
18328 caller of allocate_vectorlike that could cause overflow.
18329 Check that the new vector's length is representable as a fixnum.
18331 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18332 The previous code was bogus. For example, next_almost_prime (32)
18333 returned 39, which is undesirable as it is a multiple of 3; and
18334 next_almost_prime (24) returned 25, which is a multiple of 5 so
18335 why was the code bothering to check for multiples of 7?
18337 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18339 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18341 Variadic C functions now count arguments with ptrdiff_t.
18342 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18343 Back then I didn't know that the Emacs coding style prefers signed int.
18344 Also, in the meantime I found a few more instances where arguments
18345 were being counted with int, which may truncate counts on 64-bit
18346 machines, or EMACS_INT, which may be unnecessarily wide.
18347 * lisp.h (struct Lisp_Subr.function.aMANY)
18348 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18349 Arg counts are now ptrdiff_t, not size_t.
18350 All variadic functions and their callers changed accordingly.
18351 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18352 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18353 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18354 * callint.c (Fcall_interactively): Check arg count for overflow,
18355 to avoid potential buffer overrun. Use signed char, not 'int',
18356 for 'varies' array, so that we needn't bother to check its size
18357 calculation for overflow.
18358 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18359 * eval.c (apply_lambda):
18360 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18361 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18362 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18364 * callint.c (Fcall_interactively): Don't use index var as event count.
18366 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18367 * mem-limits.h (SIZE): Remove; no longer used.
18369 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18371 Remove unnecessary casts.
18372 * xterm.c (x_term_init):
18373 * xfns.c (x_set_border_pixel):
18374 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18375 These aren't needed now that we assume ANSI C.
18377 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18378 It's more likely to cause problems (due to unsigned overflow)
18381 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18383 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18385 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18387 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18389 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18391 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18393 GLYPH_CODE_FACE returns EMACS_INT, not int.
18394 * dispextern.h (merge_faces):
18395 * xfaces.c (merge_faces):
18396 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18397 Don't assume EMACS_INT fits in int.
18399 * character.h (CHAR_VALID_P): Remove unused parameter.
18400 * fontset.c, lisp.h, xdisp.c: All uses changed.
18402 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18404 * fns.c (concat): Minor tuning based on overflow analysis.
18405 This doesn't fix any bugs. Use int to hold character, instead
18406 of constantly refetching from Emacs object. Use XFASTINT, not
18407 XINT, for value known to be a character. Don't bother comparing
18408 a single byte to 0400, as it's always less.
18410 * floatfns.c (Fexpt):
18411 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18413 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18416 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18418 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18419 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18420 incorrectly succeed when S was a string, because 4294967386 was
18421 truncated before it was used.
18423 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18424 Otherwise, an out-of-range integer could cause undefined behavior
18427 * composite.c: Use int, not EMACS_INT, for characters.
18428 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18429 EMACS_INT, for values that are known to be in character range.
18430 This doesn't fix any bugs but is the usual style inside Emacs and
18431 may generate better code on 32-bit machines.
18433 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18434 This is for reasons similar to the recent CHAR_STRING fix.
18435 * charset.c (Fencode_char): Check that character arg is actually
18436 a character. Pass an int to ENCODE_CHAR.
18437 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18438 wider than 'int', as a compile-time check to prevent future regressions
18441 * character.c (char_string): Remove unnecessary casts.
18443 Make sure a 64-bit char is never passed to CHAR_STRING.
18444 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18445 by silently ignoring the top 32 bits, allowing some values
18446 that were far too large to be valid characters.
18447 * character.h: Include <verify.h>.
18448 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18449 arguments are no wider than unsigned, as a compile-time check
18450 to prevent future regressions in this area.
18452 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18453 (Fsubst_char_in_region):
18455 * xdisp.c (decode_mode_spec_coding):
18456 Adjust to CHAR_STRING's new requirement.
18457 * editfns.c (Finsert_char, Fsubst_char_in_region):
18458 * fns.c (concat): Check that character args are actually
18459 characters. Without this test, these functions did the wrong
18460 thing with wildly out-of-range values on 64-bit hosts.
18462 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18463 These casts should not be needed on 32-bit hosts, either.
18464 * keyboard.c (read_char):
18465 * lread.c (Fload): Remove casts to unsigned.
18467 * lisp.h (UNSIGNED_CMP): New macro.
18468 This fixes comparison bugs on 64-bit hosts.
18469 (ASCII_CHAR_P): Use it.
18470 * casefiddle.c (casify_object):
18471 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18472 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18473 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18474 * dispextern.h (FACE_FROM_ID):
18475 * keyboard.c (read_char): Use UNSIGNED_CMP.
18477 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18478 not to EMACS_INT, to avoid GCC warning.
18480 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18482 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18483 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18484 isn't needed on 32-bit machines.
18486 * buffer.c (Fgenerate_new_buffer_name):
18487 Use EMACS_INT for count, not int.
18488 (advance_to_char_boundary): Return EMACS_INT, not int.
18490 * data.c (Qcompiled_function): Now static.
18492 * window.c (window_body_lines): Now static.
18494 * image.c (gif_load): Rename local to avoid shadowing.
18496 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18497 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18498 * alloc.c (make_save_value): Integer argument is now of type
18499 ptrdiff_t, not int.
18500 (mark_object): Use ptrdiff_t, not int.
18501 * lisp.h (pD): New macro.
18502 * print.c (print_object): Use it.
18504 * alloc.c: Use EMACS_INT, not int, to count objects.
18505 (total_conses, total_markers, total_symbols, total_vector_size)
18506 (total_free_conses, total_free_markers, total_free_symbols)
18507 (total_free_floats, total_floats, total_free_intervals)
18508 (total_intervals, total_strings, total_free_strings):
18509 Now EMACS_INT, not int. All uses changed.
18510 (Fgarbage_collect): Compute overall total using a double, so that
18511 integer overflow is less likely to be a problem. Check for overflow
18512 when converting back to an integer.
18513 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18514 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18515 These were 'int' variables that could overflow on 64-bit hosts;
18516 they were never used, so remove them instead of repairing them.
18517 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18518 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18519 Previously, this ceilinged at INT_MAX, but that doesn't work on
18521 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18523 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18524 (allocate_vectorlike): Check for ptrdiff_t overflow.
18525 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18526 when a (possibly-narrower) signed value would do just as well.
18527 We prefer using signed arithmetic, to avoid comparison confusion.
18529 * alloc.c: Catch some string size overflows that we were missing.
18530 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18531 for convenience in STRING_BYTES_MAX.
18532 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18533 The definition here is exact; the one in lisp.h was approximate.
18534 (allocate_string_data): Check for string overflow. This catches
18535 some instances we weren't catching before. Also, it catches
18536 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18537 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18538 and ptrdiff_t and EMACS_INT are both 64 bits.
18540 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18541 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18542 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18544 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18546 * alloc.c (Fmake_string): Check for out-of-range init.
18548 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18550 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18552 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18554 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18555 xg_get_default_scrollbar_width.
18557 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18558 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18559 (style_changed_cb): Call update_theme_scrollbar_width and call
18560 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18561 all frames (Bug#8505).
18562 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
18563 Call gtk_window_set_resizable if HAVE_GTK3.
18564 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
18565 and height if HAVE_GTK3 (Bug#8505).
18566 (scroll_bar_width_for_theme): New variable.
18567 (update_theme_scrollbar_width): New function.
18568 (xg_get_default_scrollbar_width): Move code to
18569 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18570 (xg_initialize): Call update_theme_scrollbar_width.
18572 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18574 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18576 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18578 * frame.c (make_frame): Call other_buffer_safely instead of
18581 * window.c (temp_output_buffer_show): Call display_buffer with
18582 second argument Vtemp_buffer_show_specifiers and reset latter
18583 immediately after the call.
18584 (Vtemp_buffer_show_specifiers): New variable.
18585 (auto_window_vscroll_p, next_screen_context_lines)
18586 (Vscroll_preserve_screen_position): Remove leading asterisks from
18589 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
18591 Fix minor problems found by GCC 4.6.0 static checking.
18592 * buffer.c (Qclone_number): Remove for now, as it's unused.
18593 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
18594 (record_buffer): Remove unused local.
18595 * frame.c (other_visible_frames, frame_buffer_list): Now static.
18596 (set_frame_buffer_list): Remove; unused.
18597 * frame.h (other_visible_frames): Remove decl.
18598 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
18599 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
18600 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
18602 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
18603 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
18604 Define only if HAVE_GPM.
18605 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
18606 (update_hints_inhibit): Remove; never set. All uses removed.
18607 * widgetprv.h (emacsFrameClassRec): Remove decl.
18608 * window.c (delete_deletable_window): Now returns void, since it
18609 wasn't returning anything.
18610 (compare_window_configurations): Remove unused locals.
18611 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
18612 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
18613 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
18614 the same widths as pointers. This follows up on the 2011-05-06 patch.
18615 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
18616 * xterm.h: Likewise.
18617 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
18619 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
18621 * makefile.w32-in: Update dependencies.
18622 (LISP_H): Add lib/intprops.h.
18624 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
18626 * image.c (gif_load): Add animation frame delay to the metadata.
18627 (syms_of_image): Use DEFSYM. New symbol `delay'.
18629 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18631 * window.c (delete_deletable_window): Re-add.
18632 (Fset_window_configuration): Rewrite to handle dead buffers and
18633 consequently deletable windows.
18634 (window_tree, Fwindow_tree): Remove. Supply functionality in
18636 (compare_window_configurations): Simplify code.
18638 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
18640 * image.c (imagemagick_load_image): Fix type mismatch.
18641 (Fimagemagick_types): Likewise.
18643 * window.h (replace_buffer_in_windows): Declare.
18645 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18647 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
18648 Qclone_number. Remove external declaration of Qdelete_window.
18649 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
18651 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
18652 Run Qbuffer_list_update_hook if allowed.
18653 (Fother_buffer): Rewrite doc-string. Major rewrite for new
18654 buffer list implementation.
18655 (other_buffer_safely): New function.
18656 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by

19109 Support character positions inside a run of characters covered by a
19111 (bidi_paragraph_init, bidi_resolve_explicit_1)
19112 (bidi_level_of_next_char): Call bidi_fetch_char and
19113 bidi_fetch_char_advance instead of FETCH_CHAR and
19114 FETCH_CHAR_ADVANCE.
19115 (bidi_init_it): Initialize new members.
19116 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
19118 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
19119 instead of using explicit *_CHAR codes.
19120 (bidi_resolve_explicit, bidi_resolve_weak):
19121 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
19122 bidirectional text is supported only in multibyte buffers.
19123 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
19124 it to initialize the frame_window_p member of struct bidi_it.
19125 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
19126 (bidi_resolve_explicit, bidi_resolve_weak)
19127 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
19128 bidi_it->nchars is non-positive.
19129 (bidi_level_of_next_char): Don't try to lookup the cache for the
19130 next/previous character if nothing is cached there yet, or if we
19131 were just reseat()'ed to a new position.
19133 * xdisp.c (set_cursor_from_row): Set start and stop points
19134 according to the row's direction when priming the loop that looks
19135 for the glyph on which to display cursor.
19136 (single_display_spec_intangible_p): Function deleted.
19137 (display_prop_intangible_p): Reimplement to call
19138 handle_display_spec instead of single_display_spec_intangible_p.
19139 Accept 3 additional arguments needed by handle_display_spec.
19140 This fixes incorrect cursor motion across display property with complex
19141 values: lists, `(when COND...)' forms, etc.
19142 (single_display_spec_string_p): Support property values that are
19143 lists with the argument STRING its top-level element.
19144 (display_prop_string_p): Fix the condition for processing a
19145 property that is a list to be consistent with handle_display_spec.
19146 (handle_display_spec): New function, refactored from the
19147 last portion of handle_display_prop.
19148 (compute_display_string_pos): Accept additional argument
19149 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
19150 value of a `display' property is a "replacing spec".
19151 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19152 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
19153 the display property, but just return a value indicating whether
19154 the display property will replace the characters it covers.
19155 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
19156 frame_window_p members of struct bidi_it.
19157 (compute_display_string_pos, compute_display_string_end):
19159 (push_it): Accept second argument POSITION, where pop_it should
19160 jump to continue iteration.
19161 (reseat_1): Initialize bidi_it.disp_pos.
19163 * keyboard.c (adjust_point_for_property): Adjust the call to
19164 display_prop_intangible_p to its new signature.
19166 * dispextern.h (struct bidi_it): New member frame_window_p.
19167 (bidi_init_it): Update prototypes.

19176 Malloc failure behavior now depends on size of allocation.
19177 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
19178 * lisp.h: Change signatures accordingly.
19179 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
19180 All callers changed. (Bug#8762)
19182 * gnutls.c: Use Emacs's memory allocators.
19183 Without this change, the gnutls library would invoke malloc etc.
19184 directly, which causes problems on non-SYNC_INPUT hosts, and which
19185 runs afoul of improving memory_full behavior. (Bug#8761)
19186 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19187 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19188 xfree instead of the default malloc, realloc, free.
19189 (Fgnutls_boot): No need to check for memory allocation failure,
19190 since xmalloc does that for us.
19192 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
19193 * category.c (hash_get_category_set):
19194 * ccl.c (ccl_driver):

19210 * lisp.h (struct Lisp_Hash_Table):
19211 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
19212 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
19213 for hashes and hash indexes, instead of 'unsigned' and 'int'.
19214 * alloc.c (allocate_vectorlike):
19215 Check for overflow in vector size calculations.
19216 * ccl.c (ccl_driver):
19217 Check for overflow when converting EMACS_INT to int.
19218 * fns.c, image.c: Remove unnecessary static decls that would otherwise
19219 need to be updated by these changes.
19220 * fns.c (make_hash_table, maybe_resize_hash_table):
19221 Check for integer overflow with large hash tables.
19222 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19223 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19224 (SXHASH_REDUCE): New macro.
19225 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19226 Use it instead of discarding useful hash info with large hash values.
19227 (sxhash_float): New function.
19228 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19229 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19230 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19231 Rewrite to use FIXNUM_BITS, as this simplifies things.
19232 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19233 Adjust signatures to match updated version of code.
19234 (consing_since_gc): Now EMACS_INT, since a single hash table can
19235 use more than INT_MAX bytes.
19237 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
19239 Make it possible to build with GCC-4.6+ -O2 -flto.
19241 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
19243 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
19245 * minibuf.c (get_minibuffer, read_minibuf_unwind):
19246 Call minibuffer-inactive-mode.
19248 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
19250 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
19251 Update dependencies.
19253 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19255 * data.c (init_data): Remove code for UTS, this system is not
19258 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19260 Don't force ./temacs to start in terminal mode.
19262 * frame.c (make_initial_frame): Initialize faces in all cases, not
19263 only when CANNOT_DUMP is defined.
19264 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
19266 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19268 * dispnew.c (add_window_display_history): Use const for the string
19269 pointer. Remove declaration, not needed.
19271 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19273 Use 'inline', not 'INLINE'.
19274 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
19275 * alloc.c, fontset.c (INLINE): Remove.
19276 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
19277 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
19278 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
19279 * gmalloc.c (register_heapinfo): Use inline unconditionally.
19280 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
19282 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19284 Make it possible to run ./temacs.
19286 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19287 syms_of_callproc does the same thing. Remove test for
19288 "initialized", do it in the caller.
19289 * emacs.c (main): Avoid calling set_initial_environment when dumping.
19291 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
19293 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
19294 (read_minibuf): Use get_minibuffer.
19295 (syms_of_minibuf): Use DEFSYM.
19296 (Qmetadata): New var.
19297 * data.c (Qbuffer): Don't make it static.
19298 (syms_of_data): Use DEFSYM.
19300 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19302 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
19303 (CCL_CODE_MIN): New macro.
19305 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
19307 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
19309 * eval.c (Qdebug): Now static.
19310 * lisp.h (Qdebug): Remove decl. This reverts a part of the
19311 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
19312 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
19314 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19316 * image.c: Various fixes to ImageMagick code comments.
19317 (Fimagemagick_types): Doc fix.
19319 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
19321 Minor fixes prompted by GCC 4.6.0 warnings.
19323 * xselect.c (converted_selections, conversion_fail_tag): Now static.
19325 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
19326 (x_clipboard_manager_save_all): Move extern decl to ...
19327 * xterm.h: ... here, so that it can be checked for consistency.
19329 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19331 * xselect.c (x_clipboard_manager_save_frame)
19332 (x_clipboard_manager_save_all): New functions.
19333 (Fx_clipboard_manager_save): Lisp function deleted.
19335 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
19336 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
19338 * xterm.h: Update prototype.
19340 2011-05-28 William Xu <william.xwl@gmail.com>
19342 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
19343 exiting (Bug#8239).
19345 2011-05-28 Jim Meyering <meyering@redhat.com>
19347 Avoid a sign-extension bug in crypto_hash_function.
19348 * fns.c (to_uchar): Define.
19349 (crypto_hash_function): Use it to convert some newly-signed
19350 variables to unsigned, to avoid sign-extension bugs. For example,
19351 without this change, (md5 "truc") would evaluate to
19352 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19353 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19354 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19356 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19358 Integer overflow fixes.
19360 * dbusbind.c: Serial number integer overflow fixes.
19361 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19362 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19363 to hold a serial number that is too large for a fixnum.
19364 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19365 Check for serial numbers out of range. Decode any serial number
19366 that was so large that it became a float. (Bug#8722)
19368 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19369 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19370 Use XFASTINT rather than XUINT when numbers are nonnegative.
19371 (xd_append_arg, Fdbus_method_return_internal):
19372 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19373 arguments, check that Lisp number is nonnegative, rather than
19374 silently wrapping negative numbers around. (Bug#8722)
19375 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19378 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19380 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19382 ccl: Add integer overflow checks.
19383 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19384 (IN_INT_RANGE): New macros.
19385 (ccl_driver): Use them to check for integer overflow when
19386 decoding a CCL program. Many of the new checks are whether XINT (x)
19387 fits in int; it doesn't always, on 64-bit hosts. The new version
19388 doesn't catch all possible integer overflows, but it's an
19389 improvement. (Bug#8719)
19391 * alloc.c (make_event_array): Use XINT, not XUINT.
19392 There's no need for unsigned here.
19394 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19395 This follows up to the 2011-05-06 change that substituted uintptr_t
19396 for EMACS_INT. This case wasn't caught back then.
19398 Rework Fformat to avoid integer overflow issues.
19399 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19400 now (part of C89). Include <verify.h>.
19401 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19402 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19403 (Fformat): Avoid the prepass trying to compute sizes; it was only
19404 approximate and thus did not catch overflow reliably. Instead, walk
19405 through the format just once, formatting and computing sizes as we go,
19406 checking for integer overflow at every step, and allocating a larger
19407 buffer as needed. Keep track separately whether the format is
19408 multibyte. Keep only the most-recently calculated precision, rather
19409 than them all. Record whether each argument has been converted to
19410 string. Use EMACS_INT, not int, for byte and char and arg counts.
19411 Support field widths and precisions larger than INT_MAX. Avoid
19412 sprintf's undefined behavior with conversion specifications such as %#d
19413 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19414 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19415 formatting out-of-range floating point numbers with int
19416 formats. (Bug#8668)
19418 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19420 * data.c: Avoid integer truncation in expressions involving floats.
19421 * data.c: Include <intprops.h>.
19422 (arith_driver): When there's an integer overflow in an expression
19423 involving floating point, convert the integers to floating point
19424 so that the resulting value does not suffer from catastrophic
19425 integer truncation. For example, on a 64-bit host (* 4
19426 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19427 Do not rely on undefined behavior after integer overflow.
19429 merge count_size_as_multibyte, parse_str_to_multibyte
19430 * character.c, character.h (count_size_as_multibyte):
19431 Rename from parse_str_to_multibyte; all uses changed.
19432 Check for integer overflow.
19433 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19434 since it's now a duplicate of the other. This is more of
19435 a character than a buffer op, so better that it's in character.c.
19436 * fns.c, print.c: Adjust to above changes.
19438 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19440 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19442 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19444 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19445 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19446 (x_clipboard_manager_save): Now static.
19447 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19449 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19450 (crypto_hash_function): Now static.
19451 Fix pointer signedness problems. Avoid unnecessary initializations.
19453 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19455 * termhooks.h (Vselection_alist): Make it terminal-local.
19457 * terminal.c (create_terminal): Initialize it.
19459 * xselect.c: Support for clipboard managers.
19460 (Vselection_alist): Move to termhooks.h as terminal-local var.
19461 (LOCAL_SELECTION): New macro.
19462 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19463 (symbol_to_x_atom): Remove gratuitous arg.
19464 (x_handle_selection_request, lisp_data_to_selection_data)
19465 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19466 (x_own_selection, x_get_local_selection, x_convert_selection):
19467 New arg, specifying work frame. Use terminal-local Vselection_alist.
19468 (some_frame_on_display): Delete unused function.
19469 (Fx_own_selection_internal, Fx_get_selection_internal)
19470 (Fx_disown_selection_internal, Fx_selection_owner_p)
19471 (Fx_selection_exists_p): New optional frame arg.
19472 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19473 (x_handle_selection_clear): Don't treat other terminals with the
19474 same keyboard specially. Use the terminal-local Vselection_alist.
19475 (x_clear_frame_selections): Use Frun_hook_with_args.
19477 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19479 * xterm.h: Add support for those atoms.
19481 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19483 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19484 (converted_selections, conversion_fail_tag): New global variables.
19485 (x_selection_request_lisp_error): Free the above.
19486 (x_get_local_selection): Remove unnecessary code.
19487 (x_reply_selection_request): Args changed; handle arbitrary array
19488 of converted selections stored in converted_selections.
19489 Separate the XChangeProperty and SelectionNotify steps.
19490 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19491 (x_convert_selection): New function.
19492 (x_handle_selection_event): Simplify.
19493 (x_get_foreign_selection): Don't ignore incoming requests while
19494 waiting for an answer; this will fail when we implement
19495 SAVE_TARGETS, and seems unnecessary anyway.
19496 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19497 (Vx_sent_selection_functions): Doc fix.
19499 2011-05-26 Leo Liu <sdl.web@gmail.com>
19501 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19503 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19505 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19507 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19508 for fringe update if it has periodic bitmap.
19509 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19510 and fringe_bitmap_periodic_p.
19512 * fringe.c (get_fringe_bitmap_data): New function.
19513 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19514 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19515 row. Mark glyph row for fringe update if periodicity changed.
19517 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19518 for fringe update unless it has periodic bitmap.
19520 2011-05-25 Kenichi Handa <handa@m17n.org>
19522 * xdisp.c (get_next_display_element): Set correct it->face_id for
19523 a static composition.
19525 2011-05-24 Leo Liu <sdl.web@gmail.com>
19528 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
19530 * fns.c (crypto_hash_function, Fsha1): New function.
19531 (Fmd5): Use crypto_hash_function.
19532 (syms_of_fns): Add Ssha1.
19534 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19536 * gnutls.c: Remove unused macros.
19537 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19538 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19539 Remove macros that are defined and never used.
19540 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19542 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19544 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19545 (Fx_get_selection_internal): Minor cleanup.
19546 (Fx_own_selection_internal): Rename arguments for consistency with
19549 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19551 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19553 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19555 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19557 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19559 * dispnew.c (scrolling_window): Don't exclude the case that the
19560 last enabled row in the desired matrix touches the bottom boundary.
19562 2011-05-21 Glenn Morris <rgm@gnu.org>
19564 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19565 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19566 and add some more files.
19568 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19570 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19571 report_file_error introduced by the change from 2011-05-07.
19573 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19575 * systime.h (Time): Define only if emacs is defined.
19576 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19577 where the include path doesn't have X11/X.h by default. See
19578 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19580 2011-05-20 Kenichi Handa <handa@m17n.org>
19582 * composite.c (find_automatic_composition): Fix previous change.
19584 2011-05-20 Glenn Morris <rgm@gnu.org>
19586 * lisp.mk: New file, split from Makefile.in.
19587 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19588 (shortlisp): Remove.
19589 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19591 2011-05-19 Glenn Morris <rgm@gnu.org>
19593 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19594 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19595 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19596 (lisp): Set the order to that of loadup.el.
19597 (shortlisp): Make it a copy of $lisp.
19598 (SOME_MACHINE_LISP): Remove.
19599 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19600 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19602 2011-05-18 Kenichi Handa <handa@m17n.org>
19604 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19605 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19606 (find_automatic_composition): Mostly rewrite for efficiency.
19608 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19610 * makefile.w32-in: Update dependencies.
19612 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19614 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19615 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19617 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19619 Fix some integer overflow issues, such as string length overflow.
19621 * insdel.c (count_size_as_multibyte): Check for string overflow.
19623 * character.c (lisp_string_width): Check for string overflow.
19624 Use EMACS_INT, not int, for string indexes and lengths; in
19625 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19626 the resulting string length overflows an EMACS_INT; instead,
19627 report a string overflow if no precision given. When checking for
19628 precision exhaustion, use a check that cannot possibly have
19629 integer overflow. (Bug#8675)
19630 * character.h (lisp_string_width): Adjust to new signature.
19632 * alloc.c (string_overflow): New function.
19633 (Fmake_string): Use it. This doesn't change behavior, but saves
19634 a few bytes and will simplify future changes.
19635 * character.c (string_escape_byte8): Likewise.
19636 * lisp.h (string_overflow): New decl.
19638 Fixups, following up to the user-interface timestamp change.
19639 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19640 for UI timestamps, instead of unsigned long.
19641 * msdos.c (mouse_get_pos): Likewise.
19642 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19643 * w32gui.h (Time): Define by including "systime.h" rather than by
19644 declaring it ourselves. (Bug#8664)
19646 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19647 * image.c (clear_image_cache): Likewise.
19649 * term.c (term_mouse_position): Don't assume time_t wraparound.
19651 Be more systematic about user-interface timestamps.
19652 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19653 and sometimes 'EMACS_UINT', to represent these timestamps.
19654 This change causes it to use 'Time' uniformly, as that's what X uses.
19655 This makes the code easier to follow, and makes it easier to catch
19656 integer overflow bugs such as Bug#8664.
19657 * frame.c (Fmouse_position, Fmouse_pixel_position):
19658 Use Time, not unsigned long, for user-interface timestamps.
19659 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19660 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19661 * keyboard.h (last_event_timestamp): Likewise.
19662 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19663 * menu.h (xmenu_show): Likewise.
19664 * term.c (term_mouse_position): Likewise.
19665 * termhooks.h (struct input_event.timestamp): Likewise.
19666 (struct terminal.mouse_position_hook): Likewise.
19667 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19668 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19669 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19670 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19671 what it was before.
19672 * menu.h, termhooks.h: Include "systime.h", for Time.
19674 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19675 Don't assume that the difference between two unsigned long values
19676 can fit into an integer. At this point, we know button_down_time
19677 <= event->timestamp, so the difference must be nonnegative, so
19678 there's no need to cast the result if double-click-time is
19679 nonnegative, as it should be; check that it's nonnegative, just in
19680 case. This bug is triggered when events are more than 2**31 ms
19681 apart (about 25 days). (Bug#8664)
19683 * xselect.c (last_event_timestamp): Remove duplicate decl.
19684 (x_own_selection): Remove needless cast to unsigned long.
19686 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19687 that always fit in int. Use a sentinel instead of a counter, to
19688 avoid a temp and to allay GCC's concerns about possible int overflow.
19689 * frame.h (struct frame): Use int for menu_bar_items_used
19690 instead of EMACS_INT, since it always fits in int.
19692 * menu.c (grow_menu_items): Check for int overflow.
19694 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19696 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19697 Before, the code was not consistent. These values cannot exceed
19698 2**31 - 1 so there's no need to make them unsigned.
19699 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19700 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19701 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19703 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19705 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19706 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19707 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19708 presumably because the widths might not match.
19710 * window.c (size_window): Avoid needless test at loop start.
19712 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19714 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19716 2011-05-12 Drew Adams <drew.adams@oracle.com>
19718 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19720 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19722 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19723 `width' to `bar_area_x' and `bar_area_width', respectively.
19724 (x_scroll_run): Take account of fringe background extension.
19726 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19727 Rename local vars `left' and `width' to `bar_area_x' and
19728 `bar_area_width', respectively.
19729 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19730 background extension.
19732 2011-05-10 Jim Meyering <meyering@redhat.com>
19734 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19736 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19738 * image.c (Finit_image_library): Return t for built-in image types,
19739 like pbm and xbm. (Bug#8640)
19741 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19743 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19745 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19747 * w32console.c (Fset_screen_color): Doc fix.
19748 (Fget_screen_color): New function.
19749 (syms_of_ntterm): Defsubr it.
19751 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19752 unlink the temporary file if Fcall_process didn't create it in the
19754 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19755 child process will be redirected to a file specified with `:file'.
19756 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19757 cue to call_process_cleanup not to close that handle.
19759 2011-05-07 Ben Key <bkey76@gmail.com>
19761 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19762 one of two shell specific rules, either bootstrap-temacs-CMD or
19763 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19764 to the previous implementation of the bootstrap-temacs rule.
19765 The bootstrap-temacs-CMD rule is similar to the previous
19766 implementation of the bootstrap-temacs rule except that it
19767 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19770 These changes, along with some changes to nt/configure.bat,
19771 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19772 earlier fix to add support for --cflags and --ldflags options
19773 that include quotes so that it works whether make uses cmd or
19776 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19778 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19779 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19781 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19782 a string. Handle both cases.
19783 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19784 (Fdbus_register_method): Use Qinvalid_function.
19786 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19788 * makefile.w32-in: Update dependencies.
19789 (LISP_H): Add inttypes.h and stdin.h.
19790 (PROCESS_H): Add unistd.h.
19792 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19794 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19795 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19797 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19799 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19801 * term.c (vfatal): Remove stray call to va_end.
19802 It's not needed and the C Standard doesn't allow it here anyway.
19804 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19805 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19807 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19810 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19812 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19814 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19816 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19818 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19820 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19821 * charset.c (Fdefine_charset_internal): Don't initialize
19822 charset.code_space[15]. The value was garbage, on hosts with
19823 32-bit int (Bug#8600).
19825 * lread.c (read_integer): Be more consistent with string-to-number.
19826 Use string_to_number to do the actual conversion; this avoids
19827 rounding errors and fixes some other screwups. Without this fix,
19828 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19829 (digit_to_number): Move earlier, for benefit of read_integer.
19830 Return -1 if the digit is out of range for the base, -2 if it is
19831 not a digit in any supported base. (Bug#8602)
19833 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19835 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19836 to match comment at start of function. This also removes a
19837 GCC warning about overflow in a 32+64-bit port.
19839 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19841 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19842 Reported by Stefan Monnier in
19843 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19844 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19845 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19847 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19848 (EMACS_UINTPTR): Likewise, with uintptr_t.
19850 * lisp.h: Prefer 64-bit EMACS_INT if available.
19851 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19852 on 32-bit hosts that have 64-bit int, so that they can access
19854 However, temporarily disable this change unless the temporary
19855 symbol WIDE_EMACS_INT is defined.
19857 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19859 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19860 This removes an assumption that EMACS_INT and long are the same
19861 width as pointers. The assumption is true for Emacs porting targets
19862 now, but we want to make other targets possible.
19863 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19864 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19865 In the rest of the code, change types of integers that hold casted
19866 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19867 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19868 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19869 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19870 No need to cast type when ORing.
19871 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19872 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19873 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19874 assume EMACS_INT is the same width as char *.
19875 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19876 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19877 Remove no-longer-needed casts.
19878 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19879 (xg_tool_bar_help_callback, xg_make_tool_item):
19880 Use EMACS_INTPTR to hold an integer
19881 that will be cast to void *; this can avoid a GCC warning
19882 if EMACS_INT is not the same width as void *.
19883 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19884 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19885 (current_message_1, set_message_1):
19886 Use a local to convert to proper width without a cast.
19887 * xmenu.c (dialog_selection_callback): Likewise.
19889 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19890 Also, don't assume VALBITS / RAND_BITS is less than 5,
19891 and don't rely on undefined behavior when shifting a 1 left into
19893 * lisp.h (get_random): Change signature to match.
19895 * lread.c (hash_string): Use size_t, not int, for hash computation.
19896 Normally we prefer signed values; but hashing is special, because
19897 it's better to use unsigned division on hash table sizes so that
19898 the remainder is nonnegative. Also, size_t is the natural width
19899 for hashing into memory. The previous code used 'int', which doesn't
19900 retain enough info to hash well into very large tables.
19901 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19903 * dbusbind.c: Don't possibly lose pointer info when converting.
19904 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19905 Use XPNTR rather than XHASH, so that the high-order bits of
19906 the pointer aren't lost when converting through void *.
19908 * eval.c (Fautoload): Don't double-shift a pointer.
19910 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19912 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19914 * gnutls.c (DEF_GNUTLS_FN):
19915 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19917 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19919 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19922 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19924 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19925 New version that can reserve upto 2GB of heap space.
19927 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19929 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
19931 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
19933 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
19934 `gnutls_certificate_set_x509_key_file'.
19936 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
19938 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
19939 Update dependencies.
19941 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19943 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
19944 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19945 Remove unused parameter `fildes'.
19946 * process.c (read_process_output, send_process): Don't pass it.
19948 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19950 Fix previous change: the library cache is defined in w32.c.
19951 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19952 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
19954 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19956 Implement dynamic loading of GnuTLS on Windows.
19958 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.

19993 * process.c: Include lisp.h before w32.h, not after.
19994 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19995 instead of gnutls_record_check_pending.

20047 rather than `XVECTOR (FOO)->size'.
20049 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20050 inttypes.h, as a gnulib replacement is used if it not available in

20072 %llo or %llx format is passed. (Bug#8545)
20074 * window.c (window_scroll_line_based): Use a marker instead of
20075 simple variables to record original value of point. (Bug#7952)
20077 * doprnt.c (doprnt): Fix the case where a multibyte sequence
20078 produced by %s or %c overflows available buffer space. (Bug#8545)
20080 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20082 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

20085 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20087 * w32.c (init_environment): Warn about defaulting HOME to C:\.
20089 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20091 * keyboard.c (Qdelayed_warnings_hook): Define.
20092 (command_loop_1): Run `delayed-warnings-hook'
20093 if Vdelayed_warnings_list is non-nil.
20094 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
20095 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
20097 2011-04-28 Eli Zaretskii <eliz@gnu.org>
20099 * doprnt.c (doprnt): Don't return value smaller than the buffer
20100 size if the message was truncated. (Bug#8545).
20102 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20104 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

20111 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20113 * makefile.w32-in: Update dependencies.
20115 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20117 Improve `doprnt' and its usage. (Bug#8545)
20118 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20119 `format_end'. Remove support for %l as a conversion specifier.
20120 Don't use xrealloc. Improve diagnostics when the %l size modifier
20121 is used. Update the commentary.
20123 * eval.c (verror): Simplify calculation of size_t.
20125 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20128 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20130 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20133 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20135 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20136 This makes this file independent of the recent pseudovector change.
20138 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20140 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20142 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20143 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20144 Remove unused local.
20145 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20147 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20148 GCC 4.6.0 optimizes based on type-based alias analysis.
20149 For example, if b is of type struct buffer * and v of type struct
20150 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20151 != &v->size, and therefore "v->size = 1; b->size = 2; return
20152 v->size;" must therefore return 1. This assumption is incorrect
20153 for Emacs, since it type-puns struct Lisp_Vector * with many other
20154 types. To fix this problem, this patch adds a new type struct
20155 vectorlike_header that documents the constraints on layout of vectors
20156 and pseudovectors, and helps optimizing compilers not get fooled
20157 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20158 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20159 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20161 (XSETPVECTYPE): Rewrite in terms of new macro.
20162 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20163 This is a bit clearer, and further avoids the possibility of
20164 undesirable aliasing.
20165 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20166 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20167 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20168 since Lisp_Subr is a special case (no "next" field).
20169 (ASIZE): Now uses header.size rather than size.
20170 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20171 to avoid the hassle of writing XVECTOR (foo)->header.size.
20172 (struct vectorlike_header): New type.
20173 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20174 object, to help avoid aliasing.
20175 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20176 (SUBRP): Likewise, since Lisp_Subr is a special case.
20177 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20178 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20179 (struct Lisp_Hash_Table): Combine first two members into a single
20180 struct vectorlike_header member. All uses of "size" and "next" members
20181 changed to be "header.size" and "header.next".
20182 * buffer.h (struct buffer): Likewise.
20183 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20184 * frame.h (struct frame): Likewise.
20185 * process.h (struct Lisp_Process): Likewise.
20186 * termhooks.h (struct terminal): Likewise.
20187 * window.c (struct save_window_data, struct saved_window): Likewise.
20188 * window.h (struct window): Likewise.
20189 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20190 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20191 * buffer.c (init_buffer_once): Likewise.
20192 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20194 * process.c (Fformat_network_address): Use local var for size,
20197 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20199 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20200 * data.c (atof): Remove decl; no longer used or needed.
20201 (digit_to_number): Move to lread.c.
20202 (Fstring_to_number): Use new string_to_number function, to be
20203 consistent with how the Lisp reader treats infinities and NaNs.
20204 Do not assume that floating-point numbers represent EMACS_INT
20205 without losing information; this is not true on most 64-bit hosts.
20206 Avoid double-rounding errors, by insisting on integers when
20207 parsing non-base-10 numbers, as the documentation specifies.
20208 * lisp.h (string_to_number): New decl, replacing ...
20209 (isfloat_string): Remove.
20210 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20211 (read1): Do not accept +. and -. as integers; this
20212 appears to have been a coding error. Similarly, do not accept
20213 strings like +-1e0 as floating point numbers. Do not report
20214 overflow for integer overflows unless the base is not 10 which
20215 means we have no simple and reliable way to continue.
20216 Break out the floating-point parsing into a new
20217 function string_to_number, so that Fstring_to_number parses
20218 floating point numbers consistently with the Lisp reader.
20219 (digit_to_number): Move here from data.c. Make it static inline.
20220 (E_CHAR, EXP_INT): Remove, replacing with ...
20221 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20222 (string_to_number): New function, replacing isfloat_string.
20223 This function checks for valid syntax and produces the resulting
20224 Lisp float number too. Rework it so that string-to-number
20225 no longer mishandles examples like "1.0e+". Use strtoumax,
20226 so that overflow for non-base-10 numbers is reported only when
20227 there's no portable and simple way to convert to floating point.
20229 * textprop.c (set_text_properties_1): Rewrite for clarity,
20230 and to avoid GCC warning about integer overflow.
20232 * intervals.h (struct interval): Use EMACS_INT for members
20233 where EMACS_UINT might cause problems. See
20234 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20235 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20236 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20238 (offset_intervals): Tell GCC not to worry about length overflow
20239 when negating a negative length.
20241 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20242 (overrun_check_free): Likewise.
20244 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20245 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20248 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20249 (gnutls_make_error): Rename local to avoid shadowing.
20250 (gnutls_emacs_global_deinit): ifdef out; not used.
20251 (Fgnutls_boot): Use const for pointer to readonly storage.
20252 Comment out unused local. Fix pointer signedness problems.
20254 * lread.c (openp): Don't stuff size_t into an 'int'.
20255 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20256 about possible signed overflow.
20258 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20259 (GDK_KEY_g): Don't define if already defined.
20260 (xg_prepare_tooltip): Avoid pointer signedness problem.
20261 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20263 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20264 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20266 * xfns.c (Fx_window_property): Simplify a bit,
20267 to make a bit faster and to avoid GCC 4.6.0 warning.
20268 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20270 * fns.c (internal_equal): Don't assume size_t fits in int.
20272 * alloc.c (compact_small_strings): Tighten assertion a little.
20274 Replace pEd with more-general pI, and fix some printf arg casts.
20275 * lisp.h (pI): New macro, generalizing old pEd macro to other
20276 conversion specifiers. For example, use "...%"pI"d..." rather
20277 than "...%"pEd"...".
20278 (pEd): Remove. All uses replaced with similar uses of pI.
20279 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20280 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20281 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20282 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20283 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20284 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20285 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20287 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20288 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20289 * print.c (safe_debug_print, print_object): Likewise.
20290 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20292 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20293 avoiding the 0 flag, which is not portable.
20294 * process.c (Fmake_network_process): Use pI to avoid cast.
20295 * region-cache.c (pp_cache): Likewise.
20296 * xdisp.c (decode_mode_spec): Likewise.
20297 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
20298 behavior on 64-bit hosts with printf arg.
20299 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
20300 (x_stop_queuing_selection_requests): Likewise.
20301 (x_get_window_property): Don't truncate byte count to an 'int'
20304 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20305 here, since it parses constructs like leading '-' and spaces,
20306 which are not wanted; and it overflows with large numbers.
20307 Instead, simply match F[0-9]+, which is what is wanted anyway.
20309 * alloc.c: Remove unportable assumptions about struct layout.
20310 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20311 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20312 (allocate_vectorlike, make_pure_vector): Use the new macros,
20313 plus offsetof, to remove unportable assumptions about struct layout.
20314 These assumptions hold on all porting targets that I know of, but
20315 they are not guaranteed, they're easy to remove, and removing them
20316 makes further changes easier.
20318 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20319 This doesn't fix a bug but makes the code clearer.
20320 (string_overrun_cookie): Now const. Use initializers that
20321 don't formally overflow signed char, to avoid warnings.
20322 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20323 can cause Emacs to crash when string overrun checking is enabled.
20324 (allocate_buffer): Don't assume sizeof (struct buffer) is a
20325 multiple of sizeof (EMACS_INT); it need not be, if
20326 alignof(EMACS_INT) < sizeof (EMACS_INT).
20327 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
20329 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
20331 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
20333 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
20335 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
20336 supposed to be handshaking. (Bug#8556)
20337 Reported by Paul Eggert <eggert@cs.ucla.edu>.
20339 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
20341 * lisp.h (Qdebug): List symbol.
20342 * eval.c (Qdebug): Restore global linkage.
20343 * keyboard.c (debug-on-event): New variable.
20344 (handle_user_signal): Break into debugger when debug-on-event
20345 matches the current signal symbol.
20347 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
20349 * alloc.c (check_sblock, check_string_bytes)
20350 (check_string_free_list): Convert to standard C.
20352 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
20354 * w32.c (emacs_gnutls_push): Fix typo.
20356 2011-04-25 Eli Zaretskii <eliz@gnu.org>
20358 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
20359 "cast to pointer from integer of different size".
20361 Improve doprnt and its use in verror. (Bug#8545)
20362 * doprnt.c (doprnt): Document the set of format control sequences
20363 supported by the function. Use SAFE_ALLOCA instead of always
20366 * eval.c (verror): Don't limit the buffer size at size_max-1, that
20367 is one byte too soon. Don't use xrealloc; instead xfree and
20370 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
20372 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
20375 * gnutls.c: Renamed global_initialized to
20376 gnutls_global_initialized. Added internals for the
20377 :verify-hostname-error, :verify-error, and :verify-flags
20378 parameters of `gnutls-boot' and documented those parameters in the
20379 docstring. Start callback support.

20862 * xdisp.c (redisplay_window): Simplify code, to make it more
20863 obvious that ignore_mouse_drag_p is not accessed if !defined
20864 USE_GTK && !defined HAVE_NS.
20866 * intervals.c: Make symbols static if they're not exported.

20869 * intervals.h (merge_interval_right, delete_interval): Remove decls.
20871 * insdel.c: Make symbols static if they're not exported.
20872 However, leave prepare_to_modify_buffer alone. It's never
20873 called from outside this function, but that appears to be a bug.

20875 (adjust_after_replace, signal_before_change): Now static.
20876 (adjust_after_replace_noundo): Remove; unused.

20904 * font.c (font_close_object): Now static.
20905 * font.h (font_close_object): Remove.
20906 * fontset.c (FONTSET_OBJLIST): Remove.
20907 (free_realized_fontset) #if-0 the body, which does nothing.
20908 (face_suitable_for_char_p): #if-0, as it's never called.
20909 * fontset.h (face_suitable_for_char_p): Remove decl.
20910 * xfaces.c (face_at_string_position):
20911 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
20912 since 0 is always ASCII.
20914 * fns.c (weak_hash_tables): Now static.
20916 * fileio.c: Make symbols static if they're not exported.

20935 * editfns.c, lisp.h (get_operating_system_release): Remove.
20936 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
20937 worth the hassle of breaking this out.
20939 * xterm.c: Make symbols static if they're not exported.
20940 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

21043 * buffer.c (buffer_count): Remove unused var.

21052 * atimer.h (run_all_atimers): Remove; not exported.
21054 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
21055 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
21056 was inaccessible from Lisp.
21057 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
21058 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
21060 alloc.c: Import and export fewer symbols, and remove unused items.
21061 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
21063 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
21064 it's not optimized away by whole-program optimization.
21065 (message_enable_multibyte, free_misc): Remove.
21066 (catchlist, handlerlist, mark_backtrace):
21067 Declare only if BYTE_MARK_STACK.

21076 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
21077 (mark_backtrace): Define only if BYTE_MARK_STACK.
21078 * xdisp.c (message_enable_multibyte): Now static.
21080 Declare Lisp_Object Q* variables to be 'static' if not exported.
21081 This makes it easier for human readers (and static analyzers)
21082 to see whether these variables are used from other modules.
21083 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
21084 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
21085 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

21094 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
21096 * lisp.h (DEFINE_FUNC): Make sname 'static'.
21098 Make Emacs functions such as Fatom 'static' by default.
21099 This makes it easier for human readers (and static analyzers)
21100 to see whether these functions can be called from other modules.
21101 DEFUN now defines a static function. To make the function external
21102 so that it can be used in other C modules, use the new macro DEFUE.
21103 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
21104 (Finit_image_library):
21105 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
21106 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
21107 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
21108 Remove decls, since these functions are now static.
21109 (Funintern, Fget_internal_run_time): New decls, since these functions
21110 were already external.
21112 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
21113 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

21119 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
21120 Mark functions with DEFUE instead of DEFUN,
21121 if they are used in other modules.
21122 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
21123 decls for now-static functions.
21124 * buffer.h (Fdelete_overlay): Remove decl.
21125 * callproc.c (Fgetenv_internal): Mark as internal.

21134 * image.c (Finit_image_library): New forward static decl.
21135 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
21136 * intervals.h (Fprevious_property_change):
21137 (Fremove_list_of_text_properties): Remove decls.
21138 * keyboard.c (Fthis_command_keys): Remove decl.
21139 (Fcommand_execute): New forward static decl.

21155 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
21157 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
21160 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21162 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21163 when at ZV. (Bug#8487)
21165 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
21167 * charset.c (Fclear_charset_maps): Use xfree instead of free.
21169 * keyboard.c (parse_tool_bar_item): Likewise.
21170 * sound.c (sound_cleanup, alsa_close): Likewise.
21171 * termcap.c (tgetent): Likewise.
21172 * xfns.c (x_default_font_parameter): Likewise.
21173 * xsettings.c (read_and_apply_settings): Likewise.
21175 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21176 (overrun_check_free): Protoize.
21178 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21180 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21181 since callers should never pass a negative size.
21182 Change the signature to match that of plain 'read' and 'write'; see
21183 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21184 * lisp.h: Update prototypes of emacs_write and emacs_read.
21186 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21188 * xdisp.c (redisplay_window): Don't try to determine the character
21189 position of the scroll margin if the window start point w->startp
21190 is outside the buffer's accessible region. (Bug#8468)
21192 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21194 Fix write-region and its subroutines for buffers > 2GB.
21195 * fileio.c (a_write, e_write): Modify declaration of arguments and
21196 local variables to support buffers larger than 2GB.
21197 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21199 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21200 argument, local variables, and return value.
21202 * lisp.h: Update prototypes of emacs_write and emacs_read.
21204 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21206 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21208 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21210 Fix more problems found by GCC 4.6.0's static checks.
21212 * xdisp.c (vmessage): Use a better test for character truncation.
21214 * charset.c (load_charset_map): <, not <=, for optimization,
21215 and to avoid potential problems with integer overflow.
21216 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21217 * casetab.c (set_identity, shuffle): Likewise.
21218 * editfns.c (Fformat): Likewise.
21219 * syntax.c (skip_chars): Likewise.
21221 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21222 This also lets GCC 4.6.0 generate slightly better loop code.
21224 * callint.c (Fcall_interactively): <, not <=, for optimization.
21225 (Fcall_interactively): Count the number of arguments produced,
21226 not the number of arguments given. This is simpler and lets GCC
21227 4.6.0 generate slightly better code.
21229 * ftfont.c: Distingish more carefully between FcChar8 and char.
21230 The previous code passed unsigned char * to a functions like
21231 strlen and xstrcasecmp that expect char *, which does not
21232 conform to the C standard.
21233 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21234 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21235 char * when the C standard requires it.
21237 * keyboard.c (read_char): Remove unused var.
21239 * eval.c: Port to Windows vsnprintf (Bug#8435).
21240 Include <limits.h>.
21241 (SIZE_MAX): Define if the headers do not.
21242 (verror): Do not give up if vsnprintf returns a negative count.
21243 Instead, grow the buffer. This ports to Windows vsnprintf, which
21244 does not conform to C99. Problem reported by Eli Zaretskii.
21245 Also, simplify the allocation scheme, by avoiding the need for
21246 calling realloc, and removing the ALLOCATED variable.
21248 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21250 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21251 But keep the doprint source code for now, as we might revamp it
21252 and use it again (Bug#8435).
21253 * lisp.h (doprnt): Remove.
21254 * Makefile.in (base_obj): Remove doprnt.o.
21255 * deps.mk (doprnt.o): Remove.
21257 error: Print 32- and 64-bit integers portably (Bug#8435).
21258 Without this change, on typical 64-bit hosts error ("...%d...", N)
21259 was used to print both 32- and 64-bit integers N, which relied on
21260 undefined behavior.
21261 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21262 * lisp.h (error, verror): Mark as printf-like functions.
21263 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.

21413 This avoids several warnings with gcc -Wstrict-overflow.
21414 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21415 directly, rather than having caller test rule sign. This avoids
21416 some unnecessary tests.
21417 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21418 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21419 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21421 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21422 (xfont_open): Avoid unnecessary tests.
21424 * composite.c (composition_gstring_put_cache): Use unsigned integer.

21469 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21471 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21472 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21473 can always succeed if overflow has undefined behavior.
21475 * search.c (boyer_moore, wordify): Remove vars set but not used.
21476 (wordify): Omit three unnecessary tests.
21478 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

21506 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21507 that are set but not used.
21509 * xfns.c (make_invisible_cursor): Don't return garbage
21510 if XCreateBitmapFromData fails (Bug#8410).
21512 * xselect.c (x_get_local_selection, x_handle_property_notify):
21513 Remove vars that are set but not used.
21515 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
21516 (make_invisible_cursor): Initialize a possibly-uninitialized variable.

21537 that is set but not used.
21539 * print.c (print_object): Remove var that is set but not used.
21541 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21542 The gnulib version avoids calling malloc in the usual case,
21543 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21544 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21545 * filelock.c (current_lock_owner): Likewise.
21546 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21547 * sysdep.c: Include allocator.h, careadlinkat.h.
21548 (emacs_no_realloc_allocator): New static constant.
21549 (emacs_readlink): New function.
21550 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21551 ../lib/careadlinkat.h.
21553 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21555 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21556 first non-nil return value).

21572 (get_per_char_metric): Remove parameter `f', unused since
21573 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

21618 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21619 (FletX, Flet): Obey lexical binding.
21620 (Fcommandp): Handle closures.
21621 (Feval): New `lexical' arg.
21622 (eval_sub): New function extracted from Feval. Use it almost
21623 everywhere where Feval was used. Look up vars in lexical env.
21625 (Ffunctionp): Move from subr.el.

21627 (apply_lambda): Remove `eval_flags'.
21628 (funcall_lambda): Handle closures and new byte-code-functions.
21629 (Fspecial_variable_p): New function.
21630 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,

21633 * doc.c (Fdocumentation, store_function_docstring):
21634 * data.c (Finteractive_form): Handle closures.
21636 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21639 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21641 (exec_byte_code): New function extracted from Fbyte_code to handle new
21642 calling convention for byte-code-functions. Add new byte-codes.

21656 Limit scrolling to 100 screen lines.
21657 (redisplay_window): Even when falling back on "recentering",
21658 position point in the window according to scroll-conservatively,
21659 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21661 (try_scrolling): When point is above the window, allow searching
21662 as far as scroll_max, or one screenful, to compute vertical
21663 distance from PT to the scroll margin position. This prevents
21664 try_scrolling from unnecessarily failing when
21665 scroll-conservatively is set to a value slightly larger than the
21666 window height. Clean up the case of PT below the margin at bottom
21667 of window: scroll_max can no longer be INT_MAX. When aggressive
21668 scrolling is in use, don't let point enter the opposite scroll
21669 margin as result of the scroll.
21670 (syms_of_xdisp) <scroll-conservatively>: Document the
21671 threshold of 100 lines for never-recentering scrolling.

21680 (redisplay_internal): Remove parameter `preserve_echo_area',
21681 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21683 * indent.c (Fvertical_motion):
21684 * window.c (window_scroll_pixel_based, Frecenter):
21685 Don't pass `need_y_p' to `move_it_by_lines'.

21727 (Fbacktrace_frame): Don't assume nframes fits in int.
21729 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21731 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21734 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21736 * cm.c (calccost): Turn while-do into do-while, for clarity.
21738 * keyboard.c (syms_of_keyboard): Use the same style as later
21739 in this function when indexing through an array. This also
21740 works around GCC bug 48267.
21742 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21744 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

21747 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21749 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21750 This avoids undefined behavior on integer overflow, and is a bit
21751 more convenient anyway since it is compared to a size_t variable.
21753 Variadic C functions now count arguments with size_t, not int.
21754 This avoids an unnecessary limitation on 64-bit machines, which
21755 caused (substring ...) to crash on large vectors (Bug#8344).
21756 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21757 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
21758 All variadic functions and their callers changed accordingly.
21759 (struct gcpro.nvars): Now size_t, not int. All uses changed.

21761 * editfns.c (general_insert_function): Likewise.
21762 * eval.c (struct backtrace.nargs, interactive_p)
21763 (internal_condition_case_n, run_hook_with_args, apply_lambda)
21764 (funcall_lambda, mark_backtrace): Likewise.
21765 * fns.c (concat): Likewise.
21766 * frame.c (x_set_frame_parameters): Likewise.
21767 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21768 0 if not found, not -1. All callers changed.
21770 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21771 (stack_copy_size): Now size_t, not int.
21772 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

21778 All callers changed.
21780 * lisp.h (multibyte_char_to_unibyte):
21781 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21782 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

21788 * xdisp.c (message_dolog, set_message_1): All callers changed.
21790 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
21792 * keyboard.c (safe_run_hook_funcall): New function.
21793 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21794 don't set the hook to nil, but remove the offending function instead.
21795 (Qcommand_hook_internal): Remove, unused.
21796 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21797 Vcommand_hook_internal.
21799 * eval.c (enum run_hooks_condition): Remove.
21800 (funcall_nil, funcall_not): New functions.
21801 (run_hook_with_args): Call each function through a `funcall' argument.
21802 Remove `cond' argument, now redundant.

21809 * dispextern.h (string_buffer_position): Remove declaration.
21811 * print.c (strout): Remove parameter `multibyte', unused since
21812 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
21814 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
21815 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
21816 All callers changed.
21818 * w32.c (_wsa_errlist): Use braces for struct initializers.
21820 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
21821 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
21822 All callers changed.

21824 used outside xdisp.c).
21825 (cursor_row_p): Remove parameter `w', unused since
21826 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

21828 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
21829 All callers changed.
21831 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21833 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

21844 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
21846 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

21862 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
21864 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
21866 * w32.c (read_unc_volume): Use parameter `henum', instead of
21867 global variable `wget_enum_handle'.
21869 * keymap.c (describe_vector): Remove parameters `indices' and
21870 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

21886 * keyboard.c (readable_events):
21887 * process.c (wait_reading_process_output):
21888 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
21890 * insdel.c (adjust_markers_gap_motion):
21891 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

21976 * callint.c (Fcall_interactively):
21977 * buffer.c (Fkill_all_local_variables):
21978 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21980 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21981 unconditionally since it does the check itself.
21983 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21985 Fix more problems found by GCC 4.5.2's static checks.
21987 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21988 the first time through the loop, since we know p0 < p1 then.
21989 This also avoids a gcc -Wstrict-overflow warning.
21991 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21992 leading to a memory leak, possible in functions like
21993 load_charset_map_from_file that can allocate an unbounded number
21994 of objects (Bug#8318).
21996 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21997 that could (at least in theory) be that large.
21999 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22000 This is less likely to overflow, and avoids undefined behavior if
22001 overflow does occur. All callers changed. Use strtoul to scan
22002 for the unsigned long integer.
22003 (pint2hrstr): Simplify and tune code slightly.
22004 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
22006 * scroll.c (do_scrolling): Work around GCC bug 48228.
22007 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

22019 * process.c (Fmake_network_process): Use socklen_t, not int,
22020 where POSIX says socklen_t is required in portable programs.
22021 This fixes a porting bug on hosts like 64-bit HP-UX, where
22022 socklen_t is wider than int (Bug#8277).
22023 (Fmake_network_process, server_accept_connection):
22024 (wait_reading_process_output, read_process_output):
22027 * process.c: Rename or move locals to avoid shadowing.

22034 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
22035 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
22037 Make tparam.h and terminfo.c consistent.
22038 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22039 Include tparam.h instead, since it declares them.
22040 * cm.h (PC): Remove extern decl; tparam.h now does this.
22041 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22042 * terminfo.c: Include tparam.h, to check interfaces.
22043 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22044 (tparam): Adjust signature to match interface in tparam.h;
22045 this removes some undefined behavior. Check that outstring and len
22046 are zero, which they always are with Emacs.
22047 * tparam.h (PC, BC, UP): New extern decls.
22049 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22050 (xftfont_open): Rename locals to avoid shadowing.
22052 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
22053 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
22054 (OTF_TAG_SYM): Omit macro if not needed.

22056 (get_adstyle_property, ftfont_pattern_entity):
22057 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
22058 Rename locals to avoid shadowing.
22060 * xfont.c (xfont_list_family): Mark var as initialized.
22062 * xml.c (make_dom): Now static.
22064 * composite.c (composition_compute_stop_pos): Rename local to
22066 (composition_reseat_it): Remove unused locals.
22067 (find_automatic_composition, composition_adjust_point): Likewise.
22068 (composition_update_it): Mark var as initialized.
22069 (find_automatic_composition): Mark vars as initialized,
22070 with a FIXME (Bug#8290).
22072 character.h: Rename locals to avoid shadowing.
22073 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
22074 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
22075 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
22076 (BUF_DEC_POS): Be more systematic about renaming local temporaries
22077 to avoid shadowing.
22079 * textprop.c (property_change_between_p): Remove; unused.
22081 * intervals.c (interval_start_pos): Now static.
22083 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
22085 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
22086 Rename locals to avoid shadowing.
22088 * sound.c (wav_play, au_play, Fplay_sound_internal):
22089 Fix pointer signedness.
22090 (alsa_choose_format): Remove unused local var.
22091 (wav_play): Initialize a variable to 0, to prevent undefined
22092 behavior (Bug#8278).
22094 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22096 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22098 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22099 clobbering (Bug#8298).
22100 * sysdep.c (sys_subshell): Likewise.
22101 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22103 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22104 This should get cleaned up, so that child_setup has the
22105 same signature on all platforms.
22107 * callproc.c (call_process_cleanup): Now static.
22108 (relocate_fd): Rename locals to avoid shadowing.
22110 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
22112 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
22113 not to be necessary, and produces flickering.
22115 2011-03-20 Glenn Morris <rgm@gnu.org>
22117 * config.in: Remove file.
22119 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
22121 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
22122 are now in src/globals.h.

22149 (sigchld_handler): Now static.
22151 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
22152 That way, the code declares only the vars that it needs.
22153 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
22154 * s/cygwin.h (PTY_ITERATION): Likewise.
22155 * s/darwin.h (PTY_ITERATION): Likewise.

22158 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
22159 * process.c (allocate_pty): Don't declare stb unless it's needed.
22161 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
22162 (CONSTANTLIM): Remove; unused.
22163 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
22164 Define only if needed.
22166 * unexelf.c (unexec): Name an expression,

22237 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
22238 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
22239 some of which prompt warnings from gcc -Wbad-function-cast.
22240 (Fformat_time_string, Fencode_time, Finsert_char):
22241 (Ftranslate_region_internal, Fformat):

22269 (Fmemory_limit): Cast sbrk's returned value to char *.
22271 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

22274 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
22276 Use functions, not macros, for up- and down-casing (Bug#8254).
22277 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22278 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
22279 to use the following functions instead of these macros.
22280 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
22281 EMACS_INT, since callers assume the returned value fits in int.
22282 (upcase1): Likewise, for UPCASE_TABLE.
22283 (uppercasep, lowercasep, upcase): New static inline functions.
22284 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

22294 (regex_compile, re_match_2_internal): Mark locals as initialized.
22295 (RETALLOC_IF): Define only if needed.
22296 (WORDCHAR_P): Likewise. This one is never needed, but is used
22297 only in a comment talking about a compiler bug, so put inside
22298 the #if 0 of that comment.
22299 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22300 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

22326 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
22327 New macros, so that the caller can use some names other than
22328 gcpro1, gcpro2, etc.
22329 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22331 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22332 argument, for consistency with GCPRO2_VAR, etc: it is now the
22333 prefix of the variable, not the variable itself. All uses
22335 * dired.c (directory_files_internal, file_name_completion):
22336 Rename locals to avoid shadowing.
22338 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22339 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22340 dired.c's scmp function, had undefined behavior.
22341 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22342 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22343 * buffer.h: ... to here, because these macros use current_buffer,
22344 and the new implementation with inline functions needs to have
22345 current_buffer in scope now, rather than later when the macros
22347 (downcase, upcase1): New static inline functions.
22348 (DOWNCASE, UPCASE1): Reimplement using these functions.
22349 This avoids undefined behavior in expressions like
22350 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22351 from race conditions in accessing the global variables
22352 case_temp1 and case_temp2.
22353 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22354 * lisp.h (case_temp1, case_temp2): Remove their decls.
22355 * character.h (ASCII_CHAR_P): Move from here ...
22356 * lisp.h: ... to here, so that the inline functions mentioned
22357 above can use them.
22359 * dired.c (directory_files_internal_unwind): Now static.
22361 * fileio.c (file_name_as_directory, directory_file_name):
22362 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
22364 (file_name_as_directory): Use const pointers when appropriate.
22365 (Fexpand_file_name): Likewise. In particular, newdir might
22366 point at constant storage, so make it a const pointer.
22367 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
22368 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22370 (Fset_file_times, Finsert_file_contents, auto_save_error):

22375 to avoid shadowing.
22377 * marker.c (bytepos_to_charpos): Remove; unused.
22379 * lisp.h (verify_bytepos, count_markers): New decls,
22380 so that gcc does not warn that these functions aren't declared.
22382 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22383 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22384 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22385 (copy_text): Remove unused local var.
22387 * filelock.c (within_one_second): Now static.
22388 (lock_file_1): Rename local to avoid shadowing.
22390 * buffer.c (fix_overlays_before): Mark locals as initialized.
22391 (fix_start_end_in_overlays): Likewise. This function should be
22392 simplified by using pointers-to-pointers, but that's a different
22394 (switch_to_buffer_1): Now static.
22395 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22396 (report_overlay_modification): Rename locals to avoid shadowing.

22399 Fix pointer signedness issue.
22400 (sys_subshell): Mark local as volatile if checking for lint,
22401 to suppress a gcc -Wclobbered warning that does not seem to be right.
22402 (MAXPATHLEN): Define only if needed.
22404 * process.c (serial_open, serial_configure): Move decls from here ...
22405 * systty.h: ... to here, so that they can be checked.
22407 * fns.c (get_random, seed_random): Move extern decls from here ...
22408 * lisp.h: ... to here, so that they can be checked.
22410 * sysdep.c (reset_io): Now static.
22411 (wait_for_termination_signal): Remove; unused.
22413 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
22414 (copy_keymap_item, append_key, push_text_char_description):
22416 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
22417 (DENSE_TABLE_SIZE): Remove; unused.
22418 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
22419 (describe_map_tree):
22420 Rename locals to avoid shadowing.
22422 * keyboard.c: Declare functions static if they are not used elsewhere.

22507 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
22508 These macros can no longer be used for assignment.

22569 For example, without this patch (encode-time 0 0 0 1 1
22570 1152921504606846976) returns the obviously-bogus value (-948597
22571 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
22572 reports time overflow. See
22573 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
22574 * deps.mk (editfns.o): Depend on ../lib/intprops.h.

22589 * editfns.c (time_overflow): New function, refactoring common code.
22590 (Fformat_time_string, Fdecode_time, Fencode_time):
