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

158 * sysdep.c (list_system_processes)
159 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
160 Make it a stub in this case; otherwise the build might fail,
161 and this code hasn't been tested on such hosts anyway.
162 Problem reported by Nelson H. F. Beebe in
163 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>

177 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
178 * filelock.c: Include <c-ctype.h>.
179 (MAX_LFINFO): New top-level constant.
180 (lock_info_type): Remove members pid, boot_time. Add members at,
181 dot, colon. Change user member to be the entire buffer, not a
182 pointer. This allows us to handle the case where a foreign
183 pid or boot time exceeds the local range. All uses changed.
184 (LINKS_MIGHT_NOT_WORK): New constant.
185 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
186 (defined_WINDOWSNT): Remove.
187 (MAKE_LOCK_NAME, file_in_lock_file_name):
188 Always use .#FILE (not .#-FILE) for the file lock,
189 even if it is a regular file.
190 (rename_lock_file): New function.
191 (create_lock_file): Use it.
192 (create_lock_file, read_lock_data):
193 Prefer a symbolic link for the lock file, falling back on a
194 regular file if symlinks don't work. Do not try to create
195 symlinks on MS-Windows, due to security hassles. Stick with
196 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
197 link, rename, unlink, mkstemp) when creating locks, as a GNUish
198 host may be using a Windowsish file system, and cannot use
199 MS-Windows-only system calls. Fall back on mktemp if mkstemp
200 doesn't work. Don't fail merely because of a symlink-contents
201 length limit in the current file system; fall back on regular
202 files. Increase the symlink contents length limit to 8 KiB, this
203 should be big enough for any real use and doesn't crunch the
205 (create_lock_file, lock_file_1, read_lock_data):
206 Simplify allocation of lock file buffers now that they fit in 8 KiB.
207 (lock_file_1): Return error number, not bool. All callers changed.
208 (ELOOP): New macro, if not already defined.
209 (read_lock_data): Return size of lock file contents, not Lisp object.
210 All callers changed. Handle a race condition if some other process
211 replaces a regular-file lock with a symlink lock or vice versa,
212 while we're trying to read the lock.
213 (current_lock_owner): Parse contents more carefully, to help avoid
214 confusing a regular-file lock with some other application's use
215 of the file. Check for lock file contents being too long, or
216 not parsing correctly.
217 (current_lock_owner, lock_file):
218 Allow foreign pid and boot times that exceed the local range.
219 (current_lock_owner, lock_if_free, lock_file):
220 Simplify allocation of lock file contents.
221 * w32.c (sys_rename_replace): New function, containing most of
222 the contents of the old sys_rename.
223 (sys_rename): Use it.
224 (fchmod): New dummy function.
225 * w32.h (sys_rename_replace, fchmod): New decls.
227 2013-03-05 Eli Zaretskii <eliz@gnu.org>
229 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
230 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
231 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
232 <dmantipov@yandex.ru>.
234 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
236 * composite.c (get_composition_id, fill_gstring_header):
237 Use make_uninit_vector where appropriate.
238 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
239 * xselect.c (clean_local_selection_data): Likewise.
241 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
243 Fix misuse of ImageMagick that caused core dump (Bug#13846).
244 * image.c (imagemagick_load_image): Calculate height and width
245 after flattening the image, not before.
247 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
249 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
250 * ftfont.c (ftfont_shape_by_flt): Likewise.
251 * w32uniscribe.c (uniscribe_shape): Likewise.
253 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
255 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
256 The old approach, which fell back on DIR/.#FILE.0 through
257 DIR/.#FILE.9, had race conditions that could not be easily fixed.
258 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
259 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
260 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
261 because the locking mechanism was never reliable in that case).
262 This patch fixes this and other bugs discovered by a code
263 inspection that was prompted by
264 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
265 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
266 to avoid interoperability problems between the MS-Windows and
267 non-MS-Windows implementations. MS-Windows and non-MS-Windows
268 instances of Emacs now ignore each others' locks.
269 * filelock.c (defined_WINDOWSNT): New constant.
270 (MAKE_LOCK_NAME, fill_in_lock_file_name):
271 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
272 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
273 regular files on MS-Windows hosts.
274 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
275 Use SAFE_ALLOCA to avoid problems with long file names.
276 (MAX_LFINFO): Now a local constant, not a global macro.
277 (IS_LOCK_FILE): Remove.
278 (lock_file_1): Don't inspect errno if symlink call succeeds;
280 (lock_file): Document that this function can return if lock
282 (lock_file): Don't access freed storage.
284 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>

288 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
290 * textprop.c: Use bool for booleans.
291 (validate_interval_range, Fadd_text_properties)
292 (Fremove_text_properties): Prefer bool to int when either works.
294 2013-03-02 Eli Zaretskii <eliz@gnu.org>
296 * textprop.c (Fadd_text_properties, Fremove_text_properties):
297 If the interval tree changes as a side effect of calling
298 modify_region, re-do processing starting from the call to
299 validate_interval_range. (Bug#13743)
301 2013-02-28 Eli Zaretskii <eliz@gnu.org>
303 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
306 2013-02-27 Eli Zaretskii <eliz@gnu.org>
308 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
309 _SH_DENYRW flag, instead of emacs_open, to deny any other process
310 access to the lock file until it is written and closed.
313 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
315 * callint.c (Qcall_interactively):
316 * macros.c (Qexecute_kbd_macro):
319 2013-02-26 Bastien Guerry <bzg@gnu.org>
321 * window.c (Frecenter): Tiny docstring enhancement.
323 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
325 Minor textprop integer cleanup.
326 * intervals.h, textprop.c (add_text_properties_from_list):
327 Return void, not int, since nobody uses the return value.
328 * textprop.c (validate_plist, add_properties, remove_properties)
329 (Fadd_text_properties):
330 Don't assume list length fits in int.
331 (interval_has_all_properties, interval_has_some_properties)
332 (interval_has_some_properties_list, add_properties, remove_properties)
333 (Fadd_text_properties, Fremove_text_properties)
334 (Fremove_list_of_text_properties, text_property_stickiness):
335 Use bool for booleans.
336 (Fadd_text_properties, Fremove_text_properties):
337 (Fremove_list_of_text_properties):
338 Reindent do-while as per GNU style.

342 Implement CLASH_DETECTION for MS-Windows.
344 * filelock.c [WINDOWSNT]: Include w32.h.
345 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
346 function of that name. Up-case the macro arguments.
347 (IS_LOCK_FILE): New macro.
348 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
349 (create_lock_file): New function, with body extracted from
351 [WINDOWSNT]: Implement lock files by writing a regular file with
352 the lock information as its contents.
353 (read_lock_data): New function, on Posix platforms just calls
355 [WINDOWSNT]: Read the lock info from the file.
356 (current_lock_owner): Call read_lock_data instead of calling
357 emacs_readlinkat directly.
358 (lock_file) [WINDOWSNT]: Run the file name through
361 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
362 just check if the process by that PID exists.
364 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
365 also present, as doing so will fail to error out if the file
368 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
370 * textprop.c (Fadd_text_properties, Fremove_text_properties)
371 (Fremove_list_of_text_properties): Skip all of the intervals in
372 the region between START and END that already have resp. don't
373 have the requested properties, not just the first one.

477 2013-02-19 Eli Zaretskii <eliz@gnu.org>
479 * w32proc.c (new_child): Avoid leaking handles if the subprocess
480 resources were not orderly released.

485 the leftmost nor the rightmost, redraw both the left and the right
486 vertical borders. (Bug#13723)

508 * w32.c (sys_chown): Remove unused function.
510 * w32term.c <input_signal_count>: Declare 'volatile'
511 unconditionally. (Bug#9066)
513 * w32.c (set_errno): Reset h_errno and don't set it to any other

527 2013-02-15 Eli Zaretskii <eliz@gnu.org>
529 * keyboard.c (read_char): Fix calculation of auto-save time out
530 when auto-save-timeout is less than 4. (Bug#13720)
532 * w32proc.c (new_child): Free up to 2 slots of dead processes at a

541 value that is out of bounds.
542 (sys_accept): If fd is negative, do not set up the child_process
543 structure for reading.
545 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>

559 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
561 Fix AIX port (Bug#13650).
562 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
563 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
564 was #undeffed earlier, so it cannot be used as a macro here.
565 Use the constant and not the macro.
567 2013-02-15 Eli Zaretskii <eliz@gnu.org>
569 * w32proc.c (new_child): If no vacant slots are found in
570 child_procs[], make another pass looking for slots whose process
571 has exited or died. (Bug#13546)

601 2013-02-13 Glenn Morris <rgm@gnu.org>
603 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
605 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
607 Improve AIX port some more (Bug#13650).
608 With this, it should be as good as it was in 23.3, though it's
609 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
610 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
611 * unexaix.c (start_of_text): Remove.
612 (_data, _text): Declare as char[], not int, as AIX manual suggests.
613 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
614 (orig_load_scnptr, orig_data_scnptr):
615 Now off_t, not long, since they are file offsets.
616 (make_hdr): Use _data, not start_of_data ().
617 This is the key part of the fix.
618 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
619 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
621 * pre-crt0.c (data_start): Initialize to 1.
622 This ports to compilers that optimize the external declaration
623 'int x = 0;' as if it were 'int x;' to shrink the executable.
625 Improve AIX port (Bug#13650).
626 This doesn't fix the bug, but it makes progress: Emacs builds now.
627 * unexaix.c: Include inttypes.h, stdarg.h.
628 (report_error, report_error_1): Mark as _Noreturn.
629 (report_error): Don't report the wrong errno.
630 (report_error_1): Now varargs. All callers changed.
631 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
632 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
633 (write_ptr): Use %p to print address rather than %lx and a cast
634 to unsigned long. Grow buffer a bit, to be safer.
636 2013-02-13 Eli Zaretskii <eliz@gnu.org>
638 * bidi.c (bidi_resolve_neutral): After finding the next
639 non-neutral character, accept NEUTRAL_ON type as well, because
640 directional control characters, such as LRE and RLE, have their
641 type converted to that by bidi_resolve_weak. This avoids aborts
642 when LRE/RLE follows a run of neutrals.
643 (bidi_move_to_visually_next): Assert that return value of
644 bidi_peek_at_next_level is non-negative. Negative values will
647 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
649 Minor getenv-related fixes.
650 * callproc.c (Fcall_process_region) [!DOS_NT]:
651 Avoid unnecessary duplicate call to getenv.
652 * callproc.c (init_callproc):
653 * dispnew.c (init_display):
654 * sysdep.c (sys_subshell):
655 Omit unnecessary cast of getenv or egetenv.
657 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
659 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
662 2013-02-12 Eli Zaretskii <eliz@gnu.org>
664 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
666 (display_line): Set w->region_showing to the value of
667 it->region_beg_charpos, not to -1. This fixes redisplay
668 optimization when cursor is moved up after M->. (Bug#13623)
670 (try_scrolling): Scroll text up more if point is too close to ZV
671 and inside the scroll margin. This makes sure point is moved
672 outside the scroll margin in these cases.
674 * window.h (struct window): region_showing can no longer be
677 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
679 Tune by using memchr and memrchr.
680 * doc.c (Fsnarf_documentation):
681 * fileio.c (Fsubstitute_in_file_name):
682 * search.c (find_newline, scan_newline):
683 * xdisp.c (pos_visible_p, display_count_lines):
684 Use memchr and memrchr rather than scanning byte-by-byte.
685 * search.c (find_newline): Rename from scan_buffer.
686 Omit first arg TARGET, as it's always '\n'. All callers changed.
688 Clean up read_key_sequence a tiny bit more.
689 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
690 (read_key_sequence): Remove unused locals.
692 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
694 Clean up read_key_sequence a bit; reread active keymaps after first event.
695 * keyboard.c (read_char, read_char_x_menu_prompt)
696 (read_char_minibuf_menu_prompt):
697 Replace nmaps+maps with a single `map' arg.
698 (follow_key): Operate on a single map.
699 (active_maps): New function.
700 (test_undefined): Also return true for nil bindings.
701 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
702 a single (composed) keymap. Remember `first_event' to choose the right
703 set of active keymaps. Recompute the set of keymaps after receiving
704 the first event. Remove GOBBLE_FIRST_EVENT.
705 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
706 * keyboard.h (read_char): Update declaration.
707 * lread.c (read_filtered_event): Adjust call to read_char.
709 2013-02-11 Eli Zaretskii <eliz@gnu.org>
711 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
712 Don't use the limitation on backwards movement when lines are truncated
713 in the window. (Bug#13675)
715 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
717 * marker.c (set_marker_internal): If desired position is passed
718 as a marker, avoid call to buf_charpos_to_bytepos.
719 * window.c (Fset_window_point): Omit redundant type checking.
720 (Fset_window_start): Likewise. Format comment.
721 (window_scroll_pixel_based): Use set_marker_restricted_both
722 with character and byte positions obtained from an iterator.
723 (Fset_window_configuration): Use set_marker_restricted_both.
724 * xdisp.c (message_dolog): Likewise.
726 2013-02-10 Eli Zaretskii <eliz@gnu.org>
728 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
729 When text lines are longer than window's screen lines, don't move back
730 too far. This speeds up some redisplay operations. (Bug#13675)
732 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
734 * syntax.c (scan_sexps_forward): Fix byte position calculation
735 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
737 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
739 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
742 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
744 Minor hashing refactoring.
745 * fns.c (SXHASH_REDUCE): Move to lisp.h.
746 (sxhash_float): Return EMACS_UINT, for consistency with the other
748 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
749 non-static inline function and therefore can't use static vars.
750 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
751 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
752 with the other hash functions.
754 2013-02-09 Eli Zaretskii <eliz@gnu.org>
756 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
757 XXXXXX part of the temporary file pattern is not downcased even
758 when w32-downcase-file-names is non-nil. (Bug#13661)
760 * xdisp.c (decode_mode_spec): Remove handling of %t.
762 * msdos.c (careadlinkatcwd): Remove.
764 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
766 * lread.c (skip_dyn_bytes): New function (bug#12598).
767 (read1): Use it. Use getc instead of READCHAR to read bytes.
768 (load_each_byte): Remove. Update users.
770 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
772 * search.c (scan_buffer): Calculate end byte position just once.
773 (scan_newline): Do not recalculate start_byte.
774 (search_command): Use eassert.
775 * syntax.c (struct lisp_parse_state): New member location_byte.
776 (scan_sexps_forward): Record from_byte and avoid redundant
777 character to byte position calculation ...
778 (Fparse_partial_sexp): ... here. Break too long line.
780 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>

797 * xselect.c (selection_data_to_lisp_data): Use it.
799 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
801 * coding.c (Fdefine_coding_system_internal): Use AREF where
802 argument is known to be a vector.
803 * fns.c (Flocale_info): Likewise for ASET.
804 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
805 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
807 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
809 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
812 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
813 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
814 updateCollectionBehaviour.
816 * nsterm.m (NEW_STYLE_FS): Remove.
817 (ns_last_use_native_fullscreen): New variable.
818 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
819 (x_set_window_size): Do not take title bar and tool bar into account
820 if isFullscreen returns YES.
821 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
822 (check_native_fs): New function.
823 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
824 (ns_term_init): Remove NEW_STYLE_FS.

826 and tool bar if isFullscreen returns NO.
827 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
828 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
830 (window:willUseFullScreenPresentationOptions:): New method.
831 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
832 Hide toolbar if not enabled (Bug#13444).
833 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
834 Restore tool bar if enabled, hide it otherwise (Bug#13444).
835 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
836 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
837 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
838 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
839 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
840 (syms_of_nsterm): Add ns-use-native-fullscreen.
842 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
844 * fileio.c (Qchoose_write_coding_system): Now static.
846 2013-02-04 Eli Zaretskii <eliz@gnu.org>
848 * xdisp.c (window_buffer_changed): region_showing can be negative,
849 which still means region is being displayed.
850 (redisplay_internal): Resurrect code that forced redisplay of the
851 whole window when showing region and the mark has changed.
852 Record the new mark position to allow redisplay optimizations.
853 (display_line): If it->region_beg_charpos is non-zero, set the
854 window's region_showing member to -1. (Bug#13623) (Bug#13626)
856 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
857 not bitfield of 1 bit.
859 2013-02-03 Daniel Colascione <dancol@dancol.org>
861 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
862 daemon mode works on cygw32 when Emacs is installed and not just
865 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
867 Avoid file time stamp bug on MS-Windows (Bug#13149).
868 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
869 as FAT32 doesn't update time stamps when truncating them.
870 Also, check that a file time stamp is not a multiple of 100 ns;
871 this should catch all instances of the problem on MS-Windows,
872 as its native file system resolution is 100 ns or worse, and
873 checking for a non-multiple of 100 ns should impose only a small
874 overhead on systems with ns resolution.
876 2013-02-02 Eli Zaretskii <eliz@gnu.org>
878 Avoid encoding file names on MS-Windows when they need to be run
879 through dostounix_filename.
880 * w32.c (normalize_filename): Accept an additional argument
881 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
882 downcase it even if w32-downcase-file-names is non-nil.
883 (dostounix_filename): Accept an additional argument MULTIBYTE and
884 pass it to normalize_filename.
885 (emacs_root_dir): Adjust.
887 * msdos.h (dostounix_filename): Adjust prototype.
889 * w32.h (dostounix_filename): Adjust prototype.
891 * msdos.c (dostounix_filename): Accept an additional argument and
893 (init_environment): Adjust callers of dostounix_filename.
895 * fileio.c (Ffile_name_directory, file_name_as_directory)
896 (directory_file_name, Fexpand_file_name)
897 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
899 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
901 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
902 variables, as egetenv is case-insensitive for DOS_NT.
904 * dired.c (file_name_completion): Don't call Fdirectory_file_name
905 with an encoded file name.
907 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
908 Adjust calls to dostounix_filename.
910 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
912 * unexw32.c (unexec): Adjust call to dostounix_filename.
914 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
916 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
919 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
922 * callproc.c (Fcall_process): Make sure program name in PATH and
923 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
924 is passed to exec/spawnve, which fails unless the file-name
927 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
928 even if w32-quote-process-args is nil.
930 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
932 Fix timestamp bug when write-region appends nothing (Bug#13149).
933 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
934 the file's time stamp doesn't change if Emacs happens to write nothing
935 to the file, and on a buggy file system this could cause Emacs to
936 incorrectly infer that the file system doesn't have the bug.
937 Avoid this problem by inhibiting the inference in this case.
939 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
941 * window.h (struct window): Convert base_line_number, base_line_pos
942 and column_number_displayed members from Lisp_Object to ptrdiff_t.
943 Convert region_showing member from Lisp_Object to bitfield.
944 Remove sequence_number member. Adjust comments.
945 * window.c (sequence_number): Remove.
946 (make_window): Initialize column_number_displayed.
947 * print.c (print_object): Follow the printed representation of
948 frames and print window pointer to distinguish between windows.
949 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
950 * xdisp.c (wset_base_line_number, wset_base_line_pos)
951 (wset_column_number_displayed, wset_region_showing): Remove.
952 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
953 (try_scrolling, try_cursor_movement, redisplay_window)
954 (try_window_reusing_current_matrix, try_window_id, display_line)
955 (display_mode_lines, decode_mode_spec): Adjust users.
956 * .gdbinit (pwinx): Do not print sequence_number.
958 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
960 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
961 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
962 * dired.c: Include <fcntl.h>.
963 (open_directory): New function, which uses open and fdopendir
964 rather than opendir. DOS_NT platforms still use opendir, though.
965 (directory_files_internal, file_name_completion): Use it.
966 (file_attributes): New function, with most of the old Ffile_attributes.
967 (directory_files_internal, Ffile_attributes): Use it.
968 (file_attributes, file_name_completion_stat): First arg is now fd,
969 not dir name. All uses changed. Use fstatat rather than lstat +
971 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
972 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
973 (emacs_readlinkat): New function, with much of the old
974 Ffile_symlink_p, but with an fd argument for speed.
975 It uses readlinkat rather than careadlinkatcwd, so that it
976 need not assume the working directory.
977 (Ffile_symlink_p): Use it.
978 * filelock.c (current_lock_owner): Use emacs_readlinkat
979 rather than emacs_readlink.
980 * lisp.h (emacs_readlinkat): New decl.
981 (READLINK_BUFSIZE, emacs_readlink): Remove.
982 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
983 (emacs_norealloc_allocator, emacs_readlink): Remove.
984 This stuff is moved to fileio.c.
985 * w32.c (fstatat, readlinkat): New functions.
986 (careadlinkat): Don't check that fd == AT_FDCWD.
987 (careadlinkatcwd): Remove; no longer needed.

996 2013-01-30 Eli Zaretskii <eliz@gnu.org>
998 * w32.c (sys_open): Zero out the flags for the new file descriptor.
999 (sys_close): Zero out the flags for the file descriptor before
1000 closing it. (Bug#13546)
1002 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1003 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1004 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1007 * w32.c (w32_get_long_filename, init_environment, readlink):
1008 Support file names encoded in DBCS codepages.
1009 (readlink): Use the current file-name-coding-system, not the ANSI
1010 codepage, to decode and handle targets of symlinks.
1012 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1014 * w32.c (opendir): Now accepts a 'const char *'.
1016 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
1018 Remove obsolete redisplay code. See the discussion at
1019 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
1020 * dispnew.c (preemption_period, preemption_next_check): Remove.
1021 (Vredisplay_preemption_period): Likewise.
1022 (update_frame, update_single_window, update_window, update_frame_1):
1023 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
1024 used, following the 2012-06-22 change.
1026 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1028 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1030 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
1032 * font.c (num_fonts): Remove the leftover from old
1033 debugging code. Adjust comment style here and there.
1034 * insdel.c (insert_1): Remove.
1035 * lisp.h (insert_1): Remove prototype.
1036 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
1038 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1040 * w32.c (max_filename_mbslen): New function.
1041 (normalize_filename, readdir): Use it to detect locales where ANSI
1042 encoding of file names uses a double-byte character set (DBCS).
1043 If a DBCS encoding is used, advance by characters using
1044 CharNextExA, instead of incrementing a 'char *' pointer.
1045 Use _mbslwr instead of _strlwr. (Bug#13515)
1047 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1048 request of memory reservation to 1.7GB. (Bug#13065)
1050 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
1052 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
1053 at check_extra_latin label. (Bug#13505)
1055 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1057 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
1058 Avoid redundant calls to strlen.
1060 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1062 Drop async_visible and async_iconified fields of struct frame.
1063 This is possible because async input is gone; for details, see
1064 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1065 * frame.h (struct frame): Remove async_visible and async_iconified
1066 members, convert garbaged to unsigned bitfield. Adjust comments.
1067 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
1068 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
1069 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
1070 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
1071 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
1073 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
1074 properly. Likewise for obscured.
1076 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
1079 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
1081 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1083 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
1084 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1086 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1088 * xdisp.c (message2, message2_nolog): Remove functions.
1089 (message3, message3_nolog): Extract nbytes and multibyteness directly
1090 from the string. Change all callers.
1091 (message3_nolog): Don't set message_enable_multibyte since set_message
1092 will reset it anyway.
1093 (message1, message1_nolog): Use message3.
1094 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1095 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1096 (set_message): Drop all but the second arg, which has to be a string.
1097 (set_message_1): Simplify now that we know that a1 is NULL and the
1098 second arg is a string.
1099 * frame.h (struct frame): Remove `message_buf' field.
1100 Use glyphs_initialized_p instead.
1101 (FRAME_MESSAGE_BUF): Remove macro.
1102 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
1103 * lisp.h (message2, message2_nolog): Remove declarations.
1104 (message3, message3_nolog): Update declarations.
1105 * keyboard.c (read_char_minibuf_menu_text)
1106 (read_char_minibuf_menu_width): Remove vars.
1107 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
1108 to correctly handle multibyte strings.
1109 * frame.c (delete_frame): Don't free message_buf any more.
1110 * editfns.c (message_text, message_length): Remove vars.
1111 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1112 * fileio.c (auto_save_error): Use message3 instead of message2.
1113 * dispnew.c (adjust_frame_message_buffer): Remove function.
1115 2013-01-23 Eli Zaretskii <eliz@gnu.org>
1117 * w32term.c (w32fullscreen_hook): Account correctly for the screen
1118 real estate used for the tool bar and the menu bar.
1120 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
1122 * insdel.c (prepare_to_modify_buffer): Force redisplay if
1123 hidden buffer is prepared to modification (Bug#13164).
1125 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1127 * window.h (struct window): Change window_end_valid member from
1128 Lisp_Object to a bitfield. Adjust comments.
1129 (wset_window_end_valid): Remove.
1130 * window.c (adjust_window_count): Clear window_end_valid.
1131 (Fwindow_end): Adjust user. Remove ancient #if 0 code.

1133 (Fsplit_window_internal, Fdelete_other_windows_internal)
1134 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
1135 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
1136 * xdisp.c (check_window_end, reconsider_clip_changes)
1137 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1138 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1139 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1141 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1143 * xdisp.c (mark_window_display_accurate): Simplify the loop
1144 assuming that the only one of vchild, hchild or buffer window
1145 slots is non-nil. Call mark_window_display_accurate_1 for
1146 the leaf windows only.
1147 (mark_window_display_accurate_1): Always assume leaf window.
1150 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1152 * emacs.c (Qkill_emacs_hook): Now static.
1154 * fileio.c (Finsert_file_contents): Simplify.
1155 Remove unnecessary assignments and tests.
1157 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1159 * w32.c (acl_set_file): Don't test for errors unless
1160 set_file_security returns FALSE. Avoids spurious errors when
1163 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1165 * fileio.c (Finsert_file_contents): Revert code introduced at
1166 2013-01-18 in favor of the simpler and generally better fix.
1167 Save stack space by removing 'buffer' and reusing 'read_buf'
1170 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1172 * lisp.h (eabs): Define unconditionally (Bug#13419).
1173 The old "#if !defined (eabs)" was an unnecessary revenant of back
1174 when this macro was called "abs". Document 'eabs' better.
1176 2013-01-19 Glenn Morris <rgm@gnu.org>
1178 * fns.c (Frandom): Doc fix.
1180 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1182 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1183 segfault when there are lots of overlays.
1185 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1186 when there are lots of overlays.
1187 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1188 for the details and a way to reproduce.
1190 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1192 * fileio.c: Use O_APPEND to append.
1193 This corresponds better to the natural interpretation of "append",
1194 and avoids the need to open the output file twice, or to invoke
1195 lseek when APPEND is neither nil nor a number.
1196 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1197 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1198 file possibly twice, and lseeking to its end; this avoids the
1199 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1200 at the same time: the combination is never needed and apparently
1201 it doesn't work with DOS_NT.
1203 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1204 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1206 Allow floating-point file offsets.
1207 Problem reported by Vitalie Spinu in
1208 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1209 * fileio.c (emacs_lseek): Remove.
1210 (file_offset): New function.
1211 (Finsert_file_contents, Fwrite_region): Use it.
1213 2013-01-19 Chong Yidong <cyd@gnu.org>
1215 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1216 aborting on Fsignal (Bug#13289).
1218 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1220 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1221 set_file_security as failure due to insufficient privileges.
1222 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1223 (fstat): Return owner and group like 'stat' and 'lstat' do.
1225 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1227 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1228 The bug was observed on Ubuntu operating inside a virtual machine,
1229 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1230 The workaround introduces a race condition on non-buggy hosts,
1231 but it's an unlikely race and anyway there's a nearly identical
1232 nearby race that can't be fixed.
1233 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1235 (Fwrite_region): Test for file system time stamp bug.
1236 (init_fileio): New function.
1237 * lisp.h (init_fileio): Declare it.
1238 * emacs.c (main): Call it.
1240 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1241 and make it more consistent with other stat-failure diagnostics.
1243 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
1245 Fix crash when inserting data from non-regular files.
1246 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
1247 for the error description produced by valgrind.
1248 * fileio.c (read_non_regular): Rename to read_contents.
1249 Free Lisp_Save_Value object used to pass parameters.
1250 (read_non_regular_quit): Rename to read_contents_quit.
1251 (Finsert_file_contents): Redesign internal file reading loop to adjust
1252 gap and end positions after each read and so help make_gap to work
1253 properly. Do not signal an I/O error too early and so do not leave
1254 not yet decoded characters in a buffer, which was the reason of
1255 redisplay crash. Use list2 to build return value. Adjust comments.
1257 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1259 Close a race when statting and reading files (Bug#13149).
1260 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1261 This avoids a race if the file is renamed between stat and open.
1262 This race is not the problem originally noted in Bug#13149;
1263 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
1265 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

1272 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
1273 * alloc.c (format_save_value): Rename to make_save_value.
1274 (make_save_pointer): New function.
1275 (record_xmalloc): Use make_save_pointer.
1276 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
1277 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
1278 Change users of make_save_value to make_save_pointer.
1279 Likewise for format_save_value and make_save_value.

1295 (map_keymap_char_table_item): Adjust accordingly.
1296 * fileio.c (non_regular_fd, non_regular_inserted)
1297 (non_regular_nbytes): Remove.
1298 (Finsert_file_contents): Convert trytry to ptrdiff_t.
1299 Use format_save_value to pass parameters to read_non_regular.
1300 (read_non_regular): Use XSAVE_ macros to extract parameters.
1302 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
1304 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
1306 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1308 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
1309 extraction from any Lisp_Save_Value slot. Add type checking.
1310 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
1311 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
1312 * xselect.c: All users changed.
1314 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

1325 (save_excursion_restore): Use XSAVE_OBJECT.
1327 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
1329 Avoid needless casts with XSAVE_POINTER.
1330 * alloc.c (mark_object) [GC_MARK_STACK]:
1331 * dired.c (directory_files_internal_unwind):
1332 * fileio.c (do_auto_save_unwind):
1333 * gtkutil.c (pop_down_dialog):
1334 * keymap.c (map_keymap_char_table_item):
1335 * lread.c (load_unwind):
1336 * nsmenu.m (pop_down_menu):
1337 * print.c (print_object) [GC_MARK_STACK]:
1338 * xfns.c (clean_up_file_dialog):
1339 * xmenu.c (cleanup_widget_value_tree):
1340 Omit casts between XSAVE_POINTER and a pointer type.
1342 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
1344 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
1345 * eval.c (eval_sub): Protect `form' from being GCed before its
1346 car and cdr becomes protected with the backtrace entry.
1348 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
1350 Make Lisp_Save_Value more versatile storage for up to four objects.

1353 (XSAVE_POINTER): New macro.
1354 (XSAVE_INTEGER): Likewise.
1355 (allocate_misc): Add prototype.
1356 (free_misc): Likewise.
1357 * alloc.c (allocate_misc): Now global.
1358 (free_misc): Likewise. Adjust comment.
1359 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
1360 (free_save_value): Likewise.
1361 (mark_object): Likewise.
1362 * editfns.c (save_excursion_save): Pack everything within
1363 Lisp_Save_Value and so avoid xmalloc.
1364 (save_excursion_restore): Adjust to match new layout. Use free_misc
1365 because we do not allocate extra memory any more. Add eassert.
1366 * print.c (print_object): New code to print Lisp_Save_Value. Do not
1367 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
1368 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
1369 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:

1381 Fix SIGDANGER handlers, for AIX (Bug#13408).
1382 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
1383 Move handlers here from emacs.c; they were out of place.
1385 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
1387 * xterm.c (syms_of_xterm): Adjust documentation for
1388 scroll-bar-adjust-thumb-portion.

1407 (nsfont_list_family): Add block/unblock_input calls.
1408 (nsfont_open): Move block_input earlier. Add unblock_input before early
1410 (nsfont_draw): Add block/unblock_input calls.

1435 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
1437 Avoid unnecessary byte position calculation for the gap movement.
1438 Since all users of move_gap do CHAR_TO_BYTE for other purposes
1439 anyway, all of them should use move_gap_both instead.

1449 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
1451 * term.c (init_tty): Use them instead of rolling our own code.
1452 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
1453 switches from 'signal' to 'pthread_sigmask', which is safer in
1454 multithreaded applications.
1455 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
1456 which has already arranged for that.
1457 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
1458 This is the main part of the bug fix.

1478 right-fringe-width, scroll-bar-width and buffer-display-count.
1479 Use Qstringp for default-directory, buffer-file-name,
1480 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1481 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
1483 * data.c (store_symval_forwarding): Adjust to call the predicate.

1499 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
1500 (make_gap_1): New function to adjust the gap of any buffer.
1501 * coding.c (coding_alloc_by_making_gap): Use it.
1502 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,

1526 trailing dash is properly added.
1528 2013-01-05 Eli Zaretskii <eliz@gnu.org>
1530 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
1531 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
1532 digits for buffer positions, before misalignment starts.
1533 Display "0" for integer "object" field.
1534 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
1535 Display the newline glyph more unambiguously.
1537 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1539 * nsterm.m (ns_draw_underwave):
1540 * w32term.c (w32_draw_underwave):
1541 * xterm.c (x_draw_underwave): Make underwave look more triangular
1542 and also degrade gracefully for small fonts. (Bug#13000)
1544 * nsterm.m (ns_draw_text_decoration):
1545 * w32term.c (x_draw_glyph_string):
1546 * xterm.c (x_draw_glyph_string): Don't use previous underline
1547 thickness and position if previous underline type is underwave.
1549 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
1551 * fileio.c (Ffile_acl): Undocument return format.
1553 2013-01-02 Glenn Morris <rgm@gnu.org>

1567 * term.c (tty_ins_del_lines):
1568 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
1569 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
1571 2012-12-31 Eli Zaretskii <eliz@gnu.org>
1573 * w32.c (unsetenv): Set up the string passed to _putenv
1575 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
1576 for the bug this caused.
1578 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
1580 * coding.c (Qmac): Now static.
1582 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
1584 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
1585 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

1593 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
1594 Check toolbar_is_packed.
1595 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on

1600 (xg_update_menubar): Update title only if
1601 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1602 (xg_update_submenu): Skip tearoff only if
1603 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1604 (xg_initialize): Initialize xg_detached_menus only if
1605 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1607 * xterm.h (struct x_output): Surround handlebox_widget with
1608 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
1609 toolbar_in_hbox is bool.
1611 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
1613 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
1614 (LIBS_GNUSTEP): Define.

1618 2012-12-30 Eli Zaretskii <eliz@gnu.org>
1620 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
1621 continuation glyph on a TTY with an indication of an empty line.
1624 2012-12-29 Eli Zaretskii <eliz@gnu.org>
1626 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
1627 file's SELinux context or ACLs successfully set, nil otherwise.
1629 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.

1632 SetEvent and WaitForSingleObject.
1634 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1636 Port EXTERNALLY_VISIBLE to Clang 3.2.
1637 * conf_post.h (__has_attribute): New macro.
1638 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1640 2012-12-27 Glenn Morris <rgm@gnu.org>
1642 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1643 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1645 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1647 * fileio.c (file_name_as_directory, directory_file_name):
1648 Accept an additional argument MULTIBYTE to indicate whether the input C
1649 came from a multibyte or a unibyte Lisp string; all callers
1650 adjusted. Don't assume the input string is always multibyte.
1652 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1653 don't ENCODE_FILE them, and return a unibyte string if the input
1655 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1656 don't assume the input strings will always be multibyte. If the
1657 input strings are multibyte, decode strings obtained from C
1660 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1662 * lisp.h (toplevel): Add two notices to the comment about
1663 defining a new Lisp data type.

1667 * alloc.c (valid_lisp_object_p): Adjust comment.
1669 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1671 * keyboard.c (record_asynch_buffer_change): Initialize an event
1672 only if it's really needed.
1673 * frame.h (enum output_method): Remove output_mac member since
1674 it's a leftover from the deleted code.
1675 * frame.c (Fframep): Adjust user here ...
1676 * terminal.c (Fterminal_live_p): ... and here.
1677 * coding.c (Qmac): Now here because it's only used to denote
1678 end-of-line encoding type.
1679 (syms_of_coding): DEFSYM it.
1680 * frame.h (Qmac): Remove duplicated declaration.
1682 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1684 * window.c (select_window_1): Now static, since it's used only here.
1686 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1688 * window.c (window_body_cols): Subtract display margins from the
1689 window body width on TTYs as well. See
1690 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1691 for the original report.
1693 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1695 * xdisp.c (redisplay_window): Remove inner local variable
1696 because the outer shadowed one has the same meaning.
1697 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1699 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1700 (xg_create_tool_bar): Adjust users.
1702 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1704 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1705 * buffer.c (Fget_buffer_create): Use it to set compact field of
1706 struct buffer_text to avoid accessing an uninitialized value
1707 when compact_buffer is called for the first time.
1708 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1709 (Fset_buffer_modified_p): Use buffer_window_count to check
1710 whether the buffer is displayed in some window.
1711 * xdisp.c (message_dolog): Likewise.
1713 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1715 * w32.c (acl_set_file): If setting the file security descriptor
1716 fails, and the new DACL is identical to the existing one, silently
1717 return success. This fixes problems for users backing up their
1718 own files without having the necessary privileges for setting
1719 security descriptors.
1721 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1723 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1724 after WaitForSingleObject returns normally. This expedites reader
1725 thread shutdown when delete_child triggers it.
1726 (reap_subprocess): More accurate commentary for why we call
1727 delete_child only when cp->fd is negative.
1729 * w32.c (sys_close): Do not call delete_child on a subprocess
1730 whose handle is not yet closed. Instead, set its file descriptor
1731 to a negative value, so that reap_subprocess will call
1732 delete_child on that subprocess when its SIGCHLD arrives.
1733 This avoids closing handles used for communications between sys_select
1734 and reader_thread, which doesn't give sys_select a chance to
1735 notice that the process exited and invoke the SIGCHLD handler for
1738 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1740 * nsfns.m (Fns_do_applescript): Run event loop until script has

1751 * w32term.c (w32fullscreen_hook): New function.
1752 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1754 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1756 * fileio.c (Finsert_file_contents): Doc fix.
1758 * w32proc.c (new_child, delete_child, find_child_pid): For a
1759 subprocess, consider its slot being in use as long as its process
1760 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1761 slot when a new process is started immediately after killing
1762 another one, without waiting enough time for the first process to
1763 be reaped and resources allocated for it be orderly freed.
1765 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1767 2012-12-21 Chong Yidong <cyd@gnu.org>
1769 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1771 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1773 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1775 * w32.c (get_name_and_id): Always pass NULL as the first argument
1776 of lookup_account_sid. Avoids crashes with UNC file names that
1777 refer to DFS domains, not to specific machine names. (Bug#12621)
1778 Remove now unused argument FNAME; all callers changed.
1779 (get_file_owner_and_group): Remove now unused argument FNAME; all
1782 2012-12-21 Chong Yidong <cyd@gnu.org>
1784 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1785 error for invalid chars, don't check for a nil return value.
1787 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1789 Avoid calls to CHAR_TO_BYTE if byte position is known.
1790 * editfns.c (make_buffer_string_both): Use move_gap_both.
1791 (Fbuffer_string): Use make_buffer_string_both.

1794 (buf_bytepos_to_charpos): Likewise.
1795 (charpos_to_bytepos): Remove.
1796 * fileio.c (Finsert_file_contents): Use move_gap_both.
1797 * search.c (Freplace_match): Likewise.
1798 * process.c (process_send_region): Likewise. Use convenient
1799 names for byte positions.
1800 * lisp.h (charpos_to_bytepos): Remove prototype.
1801 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1802 * insdel.c (move_gap): Likewise.

1810 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1811 (redisplay_internal): Don't bother selecting the frame to get the
1812 proper value of frame-local variables (bug#13225).
1814 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1816 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1817 Rename 4th argument since it may be buffer or string. Adjust comment.
1818 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1820 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1822 * coding.c (Fdetect_coding_region): Do not check start and end with
1823 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1824 (code_convert_region): Likewise.
1826 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1828 * w32.c (acl_get_file, acl_set_file): Run the file name through
1829 map_w32_filename, and resolve any symlinks in the file name, like
1831 (acl_set_file): Call revert_to_self, if any privileges were

1836 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
1837 ($(BLD)/w32.$(O)): Update dependencies.
1839 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1841 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1842 propagate redisplay's scrolling (if any) to the right window.
1843 (redisplay_internal): Use ensure_selected_frame.
1844 (display_mode_lines): Complete last fix.
1845 * window.c (select_window_1): New func, extracted from select_window.
1846 (select_window): Use it.

1875 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1876 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1877 for some of that bug's symptoms can now cause Emacs to abort.
1878 Remove the workaround.
1879 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1880 The bug that caused SIGCHLD to get lost has been fixed, and the
1881 workaround for it can now cause Emacs to abort.
1883 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1885 * sysdep.c (emacs_abort): Bump backtrace size to 40.

1893 and copy ACL entries of file in addition to SELinux context if set.
1894 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
1896 * Makefile.in (LIBACL_LIBS): New macro.

1911 * w32proc.c (new_child): Initialize input_file and
1912 pending_deletion members of the child.

1931 delete the file, record it as pending deletion when the subprocess

1956 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1957 try to get accurate owner and group information from NT file
1958 security APIs. This is to make most callers of 'stat' and
1959 'lstat', which don't need that information, much faster.
1961 * dired.c (Ffile_attributes) [WINDOWSNT]:
1962 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1963 owner and group information from 'lstat'.
1965 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1967 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1968 as that confuses set-auto-coding, so insist on the head-read

1997 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1999 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2000 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2001 Remove unnecessary S_ISLNK test, as (contra the comments) this
2002 function can't copy symlinks. Improve quality of error message
2003 when attempting to copy files that are neither regular files nor

2086 (hinst): Remove unneeded extern declaration.
2087 (_start): Remove initialization of above variables; remove

2342 Fix a recently-introduced delete-process race condition.
2343 * callproc.c, process.h (record_kill_process):
2344 New function, containing part of the old call_process_kill.
2345 (call_process_kill): Use it.
2346 This does not change call_process_kill's behavior.
2347 * process.c (Fdelete_process): Use record_kill_process to fix a
2348 race condition that could cause Emacs to lose track of a child.
2350 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2352 Avoid code duplication between prev_frame and next_frame.
2353 * frame.c (candidate_frame): New function. Add comment.
2354 (prev_frame, next_frame): Use it. Adjust comment.
2356 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2358 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2359 fails, signal an error instead of continuing with an empty
2361 Encode expanded temp file pattern before passing it to mkstemp or
2364 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2365 Encode the file name before passing it to dostounix_filename, in
2366 case it will downcase it (under w32-downcase-file-names).
2369 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2371 Minor call-process cleanups.
2372 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2373 at the same time as other platforms, to simplify analysis.
2374 No need for fd0_volatile since we have synch_process_fd.
2375 Avoid needless emacs_close; arg is always negative.
2377 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2379 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2382 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2384 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2385 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2386 and mouse_face_hidden members to a bitfields.
2387 * frame.h (struct frame): Remove set-but-not-used space_width member.
2388 (FRAME_SPACE_WIDTH): Remove.
2389 * nsterm.m, w32term.c, xterm.c: Adjust users.
2390 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2391 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2392 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2393 members to a bitfields.
2395 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2397 Don't let call-process be a zombie factory (Bug#12980).
2398 Fixing this bug required some cleanup of the signal-handling code.
2399 As a side effect, this change also fixes a longstanding rare race
2400 condition whereby Emacs could mistakenly kill unrelated processes,
2401 and it fixes a bug where a second C-g does not kill a recalcitrant
2402 synchronous process in GNU/Linux and similar platforms.
2403 The patch should also fix the last vestiges of Bug#9488,
2404 a bug which has mostly been fixed on the trunk by other changes.
2405 * callproc.c, process.h (synch_process_alive, synch_process_death)
2406 (synch_process_termsig, sync_process_retcode):
2407 Remove. All uses removed, to simplify analysis and so that
2408 less consing is done inside critical sections.
2409 * callproc.c (call_process_exited): Remove. All uses replaced
2410 with !synch_process_pid.
2411 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2412 These take the role of what used to be in unwind-protect arg.
2414 (block_child_signal, unblock_child_signal):
2415 New functions, to avoid races that could kill innocent-victim processes.
2416 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2417 (call_process_kill): Record killed processes as deleted, so that
2418 zombies do not clutter up the system. Do this inside a critical
2419 section, to avoid a race that would allow the clutter.
2420 (call_process_cleanup): Fix code so that the second C-g works again
2421 on common platforms such as GNU/Linux.
2422 (Fcall_process): Create the child process in a critical section,
2423 to fix a race condition. If creating an asynchronous process,
2424 record it as deleted so that zombies do not clutter up the system.
2425 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2426 light of these changes. Omit unnecessary call to emacs_close
2427 before failure, as the unwind-protect code does that.
2428 * callproc.c (call_process_cleanup):
2429 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2430 * process.c (record_deleted_pid): New function, containing
2431 code refactored out of Fdelete_process.
2432 (Fdelete_process): Use it.
2433 (process_status_retrieved): Remove. All callers changed to use
2434 child_status_change.
2435 (record_child_status_change): Remove, folding its contents into ...
2436 (handle_child_signal): ... this signal handler. Now, this
2437 function is purely a handler for SIGCHLD, and is not called after
2438 a synchronous waitpid returns; the synchronous code is moved to
2439 wait_for_termination. There is no need to worry about reaping
2440 more than one child now.
2441 * sysdep.c (get_child_status, child_status_changed): New functions.
2442 (wait_for_termination): Now takes int * status and bool
2443 interruptible arguments, too. Do not record child status change;
2444 that's now the caller's responsibility. All callers changed.
2445 Reimplement in terms of get_child_status.
2446 (wait_for_termination_1, interruptible_wait_for_termination):
2447 Remove. All callers changed to use wait_for_termination.
2448 * syswait.h: Include <stdbool.h>, for bool.
2449 (record_child_status_change, interruptible_wait_for_termination):
2451 (record_deleted_pid, child_status_changed): New decls.
2452 (wait_for_termination): Adjust to API changes noted above.
2454 * bytecode.c, lisp.h (Qbytecode): Remove.
2455 No longer needed after 2012-11-20 interactive-p changes.
2457 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2459 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2460 the scroll margin, move point outside the margin. (Bug#13055)
2462 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2464 * gtkutil.c (my_log_handler): New function.
2465 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2467 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2469 * lisp.h (modify_region): Rename to...
2470 (modify_region_1): ...new prototype.
2471 * textprop.c (modify_region): Now static. Adjust users.
2472 * insdel.c (modify_region): Rename to...
2473 (modify_region_1): ...new function to work with current buffer.
2474 Adjust comment and users. Use true and false for booleans.
2476 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2478 * alloc.c (free_save_value): New function.
2479 (safe_alloca_unwind): Use it.
2480 * lisp.h (free_save_value): New prototype.
2481 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2483 (save_excursion_restore): Adjust to match saved data structure.
2484 Use free_save_value to offload some work from GC. Drop obsolete
2487 2012-12-03 Chong Yidong <cyd@gnu.org>
2489 * fileio.c (Vauto_save_list_file_name): Doc fix.
2491 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2493 * w32fns.c: Remove prototype of atof.
2494 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2496 (file_dialog_callback): Make it UINT_PTR.
2498 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2501 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2502 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2505 2012-12-03 Glenn Morris <rgm@gnu.org>
2507 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2509 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2511 Fix xpalloc confusion after memory is exhausted.
2512 * alloc.c (xpalloc): Comment fix.
2513 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2514 and signals an error, do not clear charset_table_size, as
2515 charset_table is still valid.
2516 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2518 Use execve to avoid need to munge environ (Bug#13054).
2519 * callproc.c (Fcall_process):
2520 * process.c (create_process):
2521 Don't save and restore environ; no longer needed.
2522 * callproc.c (child_setup):
2523 Use execve, not execvp, to preserve environ.
2525 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2527 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2529 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2531 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2532 display for sliced images (Bug#10500).
2534 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2536 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2538 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2539 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2541 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2543 * xdisp.c (window_outdated): Remove eassert since it hits
2544 some suspicious corner cases (see Bug#13007 and Bug#13012).
2545 (mode_line_update_needed): New function.
2546 (redisplay_internal, redisplay_window): Use it.
2547 (ensure_selected_frame): New function.
2548 (redisplay_internal, unwind_redisplay): Use it.
2549 (redisplay_internal): Move comment about buffer_shared...
2550 (buffer_shared_and_changed): ...near to its real use.
2552 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2554 * callproc.c (Fcall_process): Don't misreport vfork failure.
2556 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2558 * callproc.c (Fcall_process): Fix vfork portability problems.
2559 Do not assume that fd[0], count, filefd, and save_environ survive
2560 vfork. Fix bug whereby wrong errno value could be reported for
2561 pipe failure. Some minor cleanups, too, as follows. Move buf and
2562 bufsize to the context where they're needed. Change new_argv to
2563 be of type char **, as this is more convenient and avoids casts.
2564 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2565 Now local constants, not macros.
2567 2012-11-18 Kenichi Handa <handa@gnu.org>
2569 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2570 for the variable "f".
2572 2012-11-13 Kenichi Handa <handa@gnu.org>
2574 * font.c (font_unparse_xlfd): Exclude special characters from the
2575 generating XLFD name.
2577 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
2579 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

2581 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
2583 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

2590 * lread.c (readbyte_from_file): Assume EINTR is defined.
2591 * process.c (wait_reading_process_output, send_process) [subprocesses]:
2592 Assume EIO and EAGAIN are defined.
2593 * unexcoff.c (write_segment): Assume EFAULT is defined.
2595 2012-11-27 Eli Zaretskii <eliz@gnu.org>

2600 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
2601 highlighting on the frame was cleared. Prevents assertion
2602 violations when repeatedly clicking on the "Top" link of the
2603 "bread-crumbs" in Info buffers.

2617 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2618 between bpos_covered and bpos_max. This fixes cursor display when
2619 several display strings follow each other.
2621 * .gdbinit (pgx): If the glyph's object is a string, display the
2622 pointer to string data, rather than the value of the string object
2623 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2625 * indent.c (Fvertical_motion): If the starting position is covered
2626 by a display string, return to one position before that, to avoid
2627 overshooting it inside move_it_to. (Bug#12930)
2629 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>

2640 Drop unused pending_menu_activation member.
2641 * xterm.h (struct x_output): Drop outdated #if 0 code.
2642 Use bitfields for explicit_parent, asked_for_visible,
2643 has_been_visible and net_wm_state_hidden_seen members.

2648 of a literal "/". (Bug#12955)
2649 (gl-stamp): Invoke fc.exe directly, not through cmd.

2654 * dired.c: Assume HAVE_DIRENT_H.
2655 (NAMLEN): Remove, replacing with ...
2656 (dirent_namelen): New function. All uses changed. Use the GNU macro
2657 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2658 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2659 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2660 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2662 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2663 * ndir.h: Rename to ../nt/inc/dirent.h.
2664 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2665 Do not include <dirent.h>; no longer needed.
2666 * w32.c: Include <dirent.h> rather than "ndir.h".
2668 2012-11-23 Chong Yidong <cyd@gnu.org>
2670 * xftfont.c (xftfont_open): Remove duplicate assignment.
2672 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2674 * alloc.c (Fgarbage_collect): Unblock input after clearing
2675 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2676 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2677 * msdos.c (IT_frame_up_to_date): Use it here...
2678 * w32term.c (w32_frame_up_to_date): ...here...
2679 * xterm.c (XTframe_up_to_date): ...and here...
2680 * nsterm.m (ns_frame_up_to_date): ...but not here.
2681 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2683 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2684 Do not check whether GC is in progress.

2688 * xdisp.c (window_buffer_changed): New function.
2689 (update_menu_bar, update_tool_bar): Use it to
2690 simplify large 'if' statements.

2692 'tail' and 'frame' local variables.
2694 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2696 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2697 with Windows system header.
2699 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2701 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).

2719 Cygwin builds, not just GTK builds. See
2720 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2722 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2724 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2725 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2726 Define for the MSVC compiler.
2728 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2730 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2731 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2732 dostounix_filename. Prevents crashes down the road, because
2733 dostounix_filename assumes it gets a unibyte string.
2734 Reported by Michel de Ruiter <michel@sentient.nl>, see

2761 (text_outside_line_unchanged_p, redisplay_window): Use it.
2762 (redisplay_internal): Likewise. Fix indentation.

2773 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2774 cygwin_convert_file_name*.
2776 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2777 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2779 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>

2783 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2785 * w32select.c: Include w32common.h before w32term.h, so that
2786 windows.h gets included before w32term.h uses some of its
2787 features, see below.
2789 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2791 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

2797 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2798 (ns_select): Return at once if events are held (Bug#12834).
2800 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2802 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2803 Needed following 2012-10-20 change. (Bug#12902)
2805 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2807 * w32proc.c (waitpid): Remove unused label get_result.
2809 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2811 * makefile.w32-in (SYSWAIT_H): New macro.
2812 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2813 ($(BLD)/sysdep.$(O)): Update dependencies.
2815 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2817 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2818 * callproc.c (relocate_fd): Assume F_DUPFD.
2819 * emacs.c, term.c (O_RDWR): Remove.
2820 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2821 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2822 * nsterm.m: Assume <fcntl.h> exists.
2823 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2824 (create_pty, Fmake_network_process, server_accept_connection)
2825 (wait_reading_process_output, init_process_emacs):
2827 (wait_reading_process_output): Put in a special case for WINDOWSNT
2828 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2829 It's not clear this is needed, but it's a more-conservative change.
2830 (create_process): Assume FD_CLOEXEC.
2831 (create_process, create_pty): Assume O_NOCTTY.
2832 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2833 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2834 Omit if not DOS_NT, since F_GETFL is not defined there.
2835 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2836 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2838 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2839 lack it, since gnulib guarantees this.
2840 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2842 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2844 * w32.c (faccessat): Pretend that directories have the execute bit
2845 set. Emacs expects that, e.g., in files.el:cd-absolute.
2847 * w32proc.c (create_child): Don't clip the PID of the child
2848 process to fit into an Emacs integer, as this is no longer a
2850 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2851 reaping only the process specified by PID argument, if that is
2852 positive. Use PID instead of dead_child to know which process to
2853 reap. Wait for the child to die only if WNOHANG is not in
2855 (sys_select): Don't set dead_child.
2857 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2858 as it is no longer needed.
2860 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2862 (record_child_status_change): Remove the setting of
2863 record_at_most_one_child for the !WNOHANG case.
2865 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2867 Fix problems in ns port found by static checking.
2868 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2869 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2870 not to process group.
2871 (ns_select): Use emacs_write, not write, as that's more robust
2872 in the presence of signals.
2873 (fd_handler:): Check for read errors.
2875 2012-11-16 Glenn Morris <rgm@gnu.org>
2877 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2879 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2881 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2883 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2885 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2886 use the same value of thread handle.
2887 (start_timer_thread): If the timer thread exited (due to error),
2888 clean up by closing the two handles it used. Duplicate the caller
2889 thread's handle here, so it gets duplicated only once, when
2890 launching the timer thread. Set priority of the timer thread, not
2892 (getitimer): Don't duplicate the caller thread's handle here.
2895 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2897 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2900 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2902 Remove no-longer-used pty_max_bytes variable.
2903 * process.c (pty_max_bytes): Remove; unused.
2904 (send_process): Do not set it.
2906 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2908 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2909 Update dependencies.
2911 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2913 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2914 This follows up on the 2012-09-29 patch that removed indirection
2915 for the 'function' field. Reported by Sergey Vinokurov in
2916 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2918 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2920 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2921 different name, as the MS runtime does not have such a function,
2922 and probably never will.) All callers changed. Ignore DIRFD
2923 value if PATH is an absolute file name, to match Posix spec
2924 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2927 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2929 * xdisp.c (echo_area_display, redisplay_internal):
2930 Omit redundant check whether frame_garbaged is set.
2932 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2934 Use faccessat, not access, when checking file permissions (Bug#12632).
2935 This fixes a bug that has been present in Emacs since its creation.
2936 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2937 which must set some sort of record. (Torek's bug report was against
2938 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2939 same common flaw.) See Torek's Usenet posting
2940 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2941 Posted: Fri Apr 8 14:18:56 1983.
2942 * Makefile.in (LIB_EACCESS): New macro.
2944 * callproc.c (init_callproc):
2945 * charset.c (init_charset):
2946 * fileio.c (check_existing, check_executable, check_writable)
2948 * lread.c (openp, load_path_check):
2949 * process.c (allocate_pty):
2951 Use effective UID when checking permissions, not real UID.
2952 * callproc.c (init_callproc):
2953 * charset.c (init_charset):
2954 * lread.c (load_path_check, init_lread):
2955 Test whether directories are accessible, not merely whether they exist.
2956 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2957 * fileio.c (check_existing, check_executable, check_writable)
2959 Use symbolic names instead of integers for the flags, as they're
2961 (check_writable): New arg AMODE. All uses changed.
2962 Set errno on failure.
2963 (Ffile_readable_p): Use faccessat, not stat + open + close.
2964 (Ffile_writable_p): No need to call check_existing + check_writable.
2965 Just call check_writable and then look at errno. This saves a syscall.
2966 dir should never be nil; replace an unnecessary runtime check
2967 with an eassert. When checking the parent directory of a nonexistent
2968 file, check that the directory is searchable as well as writable, as
2969 we can't create files in unsearchable directories.
2970 (file_directory_p): New function, which uses 'stat' on most platforms
2971 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2972 (Ffile_directory_p, Fset_file_times): Use it.
2973 (file_accessible_directory_p): New function, which uses a single
2974 syscall for efficiency.
2975 (Ffile_accessible_directory_p): Use it.
2976 * xrdb.c (file_p): Use file_directory_p.
2977 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2978 * lread.c (openp): When opening a file, use fstat rather than
2979 stat, as that avoids a permissions race. When not opening a file,
2980 use file_directory_p rather than stat.
2981 (dir_warning): First arg is now a usage string, not a format.
2982 Use errno. All uses changed.
2983 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2984 that merely introduced a race.
2985 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2986 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2987 and similarly for the other O_* flags.
2988 * w32.c (sys_faccessat): Rename from sys_access and switch to
2989 faccessat's API. All uses changed.
2990 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2991 (magic_db): Rename from magic_file_p.
2992 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2993 char *, so that we don't have to test for file existence
2994 separately from opening the file for reading. This removes a race
2995 fixes a permission-checking problem, and simplifies the code.
2997 (file_p): Remove; no longer needed.
2999 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3001 Omit glyphs initialization at startup.
3002 * dispnew.c (glyphs_initialized_initially_p): Remove.
3003 (adjust_frame_glyphs_initially): Likewise. Adjust users.
3004 (Fredraw_frame): Move actual code from here...
3005 (redraw_frame): ...to here. Add eassert. Adjust comment.
3006 (Fredraw_display): Use redraw_frame.
3007 * xdisp.c (clear_garbaged_frames): Likewise.
3009 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3011 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3012 passed to pint2str and pint2hrstr to be at most the size of the
3013 frame's decode_mode_spec_buffer. This avoids crashes with very
3014 large values of FIELD_WIDTH argument to decode_mode_spec.
3017 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3019 Fix a race with verify-visited-file-modtime (Bug#12863).
3020 Since at least 1991 Emacs has ignored an mtime difference of no
3021 more than one second, but my guess is that this was to work around
3022 file system bugs that were fixed long ago. Since the race is
3023 causing problems now, let's remove that code.
3024 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3025 whose time stamp is off by no more than a second. Insist that the
3026 file time stamps match exactly.
3028 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3030 * frame.h (struct frame): Convert external_tool_bar member to
3031 1-bit unsigned bitfield.
3032 * termhooks.h (struct terminal): Remove mouse_moved member since
3033 all users are long dead. Adjust comment on mouse_position_hook.
3035 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3037 Simplify by using FOR_EACH_FRAME here and there.
3038 * frame.c (next_frame, prev_frame, other_visible_frames)
3039 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
3040 * w32term.c (x_window_to_scroll_bar): Likewise.
3041 * window.c (window_list): Likewise.
3042 * xdisp.c (x_consider_frame_title): Likewise.
3043 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
3044 * xfns.c (x_window_to_frame, x_any_window_to_frame)
3045 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
3046 * xmenu.c (menubar_id_to_frame): Likewise.
3047 * xselect.c (frame_for_x_selection): Likewise.
3048 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3049 (x_window_to_menu_bar): Likewise.
3050 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3052 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3054 * data.c (Qdefalias_fset_function): Now static.
3056 Another tweak to vectorlike_header change.
3057 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3058 Remove, and replace all uses with ...
3059 (next_in_free_list, set_next_in_free_list):
3060 New functions, which respect C's aliasing rules better.
3062 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3064 * window.c (list4i): Rename from 'quad'. All uses changed.
3065 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3067 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3069 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3070 warning about mixing declarations and code in ISO C90.
3072 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3074 * window.c (Fsplit_window_internal): Set combination limit of
3075 new parent window to t iff Vwindow_combination_limit is t;
3076 fixing a regression introduced with the change from 2012-09-22.
3077 (Fset_window_combination_limit): Fix doc-string.
3079 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3081 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3082 amount when the scroll margins are too large. When scrolling
3083 backwards in the buffer, give up if cannot reach point or the
3084 scroll margin within a reasonable number of screen lines.
3085 Fixes point position in window under scroll-up/down-aggressively when
3086 point is positioned many lines beyond the window top/bottom.
3089 * ralloc.c (relinquish): If real_morecore fails to return memory
3090 to the system, don't crash; instead, leave the last heap
3091 unchanged and return. (Bug#12774)
3093 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3095 * lisp.h (AUTOLOADP): New macro.
3096 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
3097 * data.c (Ffset): Remove special ad-advice-info handling.
3098 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
3100 (Finteractive_form): Simplify.
3101 (Fquo): Don't insist on having at least 2 arguments.
3102 (Qdefalias_fset_function): New var.
3104 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3106 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

3112 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3114 Fix recently introduced crash on MS-Windows (Bug#12839).
3115 * w32term.h (struct scroll_bar): Use convenient header.
3116 (SCROLL_BAR_VEC_SIZE): Remove.
3117 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3119 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3121 Tweak last vectorlike_header change.
3122 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3123 vectorlike object on the free list. This is introduced to avoid
3124 some (but not all) pointer casting and aliasing problems, see
3125 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3126 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
3128 (xvectype, xvecsize): Use them to examine Lisp_Object values.
3130 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3132 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3133 been removed, so remove them here also.
3135 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3137 * doc.c (Fdocumentation): Handle new property
3138 dynamic-docstring-function to replace the old ad-advice-info.
3140 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
3142 * fns.c (Qeql, hashtest_eq): Now static.

3151 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
3153 Use same hash function for hashfn_profiler as for hash_string etc.
3154 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
3155 * lisp.h (sxhash_combine): New inline function, with the contents
3156 of the old SXHASH_COMBINE.
3157 * profiler.c (hashfn_profiler): Use it, instead of having a
3158 special hash function containing a comparison that always yields 1.
3160 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3162 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3163 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3164 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3167 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3169 * image.c (xpm_make_color_table_h): Fix compiler error because
3170 make_hash_table changed.
3172 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
3174 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3176 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3178 Use ad-hoc comparison function for the profiler's hash-tables.
3179 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3180 (make_log): Use them.
3181 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3182 call Fequal any more.

3191 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
3192 (hash_lookup, hash_remove_from_table): Move assertion checking of
3193 hashfn result here. Check hash-equality before calling cmpfn.

3203 2012-11-08 Eli Zaretskii <eliz@gnu.org>
3205 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
3206 value of w32-scroll-lock-modifier is neither nil nor one of the
3207 known key modifiers. (Bug#12806)
3209 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3211 Shrink struct vectorlike_header to the only size field.
3212 * lisp.h (enum pvec_type): Avoid explicit enum member values.
3214 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
3215 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
3216 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
3217 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
3218 information from the vector header. Adjust comment.

3229 (NEXT_IN_FREE_LIST): New macro.
3230 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
3231 (Fmake_bool_vector): Likewise.
3232 (struct large_vector): New type to represent allocation unit for
3233 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3234 (large_vectors): Change type to struct large_vector.
3235 (allocate_vector_from_block): Simplify.
3236 (PSEUDOVECTOR_NBYTES): Replace with...
3237 (vector_nbytes): ...new function. Adjust users.

3243 (live_vector_p): Adjust to match large vector.
3244 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
3245 * buffer.h (struct buffer): Add next member.
3246 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
3248 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
3249 * fns.c (internal_equal): Adjust to match enum pvec_type change.
3250 (copy_hash_table): Adjust to match vector header change.
3251 * lread.c (defsubr): Use XSETPVECTYPE.
3252 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
3253 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
3254 (xvecsize): New command.
3256 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3258 * keyboard.c (event_to_kboard): Do not dereference
3259 frame_or_window field of SELECTION_REQUEST_EVENT
3260 and SELECTION_CLEAR_EVENT events (Bug#12814).
3261 * xterm.h (struct selection_input_event): Adjust comment.
3263 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3265 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3266 such as Scroll Lock, if the respective keys are treated as
3267 function keys, not as modifiers. This avoids destroying non-ASCII
3268 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3270 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3272 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3274 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3276 Restore some duplicate definitions (Bug#12814).
3277 This undoes part of the 2012-11-03 changes. Some people build
3278 with plain -g rather than with -g3, and they need the duplicate
3279 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3280 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3281 Define as macros, as well as as enums or as constants.
3283 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
3285 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
3286 to keypad keys (Bug#12816).
3288 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3290 Minor adjustments of recently-changed frame functions.
3291 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3292 known to be a frame (we're in the FRAMEP branch).
3293 * lisp.h (Qframep): Remove decl. frame.h declares this.
3294 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3295 since they're meant for Lisp fixnum values.
3297 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3299 * window.c (Fwindow_combination_limit): Revert to the only
3300 required argument and adjust docstring as suggested in
3301 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3302 by Martin Rudalics <rudalics@gmx.at>.
3304 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3306 Widely used frame validity and checking functions.
3307 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
3308 * frame.c (decode_live_frame, decode_any_frame): New functions.
3309 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
3310 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
3311 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
3312 (Fframe_pointer_visible_p): Use decode_any_frame.
3313 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
3314 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
3315 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
3316 (Fframe_focus): Likewise. Allow zero number of arguments.
3318 (frame_buffer_list, frame_buffer_predicate): Remove.
3319 * lisp.h (frame_buffer_predicate): Remove prototype.
3320 * buffer.c (Fother_buffer): Use decode_any_frame.
3321 * xdisp.c (Ftool_bar_lines_needed): Likewise.
3322 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3323 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3324 (Fclose_font, Ffont_info): Use decode_live_frame.
3325 * fontset.c (check_fontset_name): Likewise.
3326 * terminal.c (Fframe_terminal): Likewise.
3327 * w32fns.c (check_x_frame): Likewise.
3328 * window.c (Fminibuffer_window, Fwindow_at)
3329 (Fcurrent_window_configuration): Likewise.
3330 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
3331 Likewise. Allow zero number of arguments. Adjust docstring.
3332 * dispnew.c (Fredraw_frame): Likewise.
3333 * xfaces.c (frame_or_selected_frame): Remove.
3334 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3335 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3336 (Fframe_face_alist): Use decode_live_frame.
3337 * xfns.c (check_x_frame): Likewise.
3339 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3341 * window.c (quad): New function.
3342 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3343 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3344 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3345 (Fwindow_line_height): Use it.
3346 (Fwindow_fringes): Use list3.
3347 (Fwindow_scroll_bars): Use list4.
3348 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3349 (Fwindow_combination_limit): Allow zero number of arguments.
3351 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3353 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3355 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3356 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3357 file descriptor 2 for standard error. (Bug#12805)
3359 2012-11-05 Chong Yidong <cyd@gnu.org>
3361 * process.c (wait_reading_process_output): Revert previous change.
3363 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3365 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3366 This removes code that has been obsolete since around 1990.
3367 * callproc.c (Fcall_process):
3369 * process.c (create_process):
3370 * term.c (dissociate_if_controlling_tty):
3371 Assume setsid exists.
3372 * callproc.c (child_setup): Assume setpgid exists and behaves as
3373 per POSIX.1-1988 or later.
3374 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3375 * emacs.c (shut_down_emacs):
3376 * sysdep.c (sys_suspend, init_foreground_group):
3377 Assume getpgrp behaves as per POSIX.1-1998 or later.
3378 * msdos.c (setpgrp): Remove.
3379 (tcgetpgrp, setpgid, setsid): New functions.
3380 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3381 * term.c (no_controlling_tty): Remove; unused.
3382 * w32proc.c (setpgrp): Remove.
3383 (setsid, tcgetpgrp): New functions.
3385 Simplify by assuming __fpending.
3386 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3387 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3388 Do not assume that __fpending's result fits in int.
3390 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3392 Remove EMACS_OUTQSIZE+sleep hack.
3393 * dispnew.c (update_frame_1): Remove hack for terminals slower
3394 than 2400 bps, which throttled Emacs by having it sleep.
3395 This code hasn't worked since at least 2007, when the multi-tty stuff
3396 was added, and anyway those old terminals are long dead.
3397 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3398 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3400 Fix data-loss with --version (Bug#9574).
3401 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3402 as we can't assume that emacs_strerror is initialized, and strerror
3403 is good enough here.
3404 (main): Invoke atexit earlier, to catch earlier instances of
3405 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3407 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3409 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3410 (keyDown): Remap keypad keys to X11 virtual key codes.
3412 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3414 Fix data-loss with --batch (Bug#9574).
3415 * emacs.c: Include <close-stream.h>.
3416 (close_output_streams): New function.
3417 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3418 and handles errors appropriately.
3419 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3422 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3423 The symptom is a diagnostic "GLib-WARNING **: In call to
3424 g_spawn_sync(), exit status of a child process was requested but
3425 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3426 waitpid(), so exit status can't be returned." The diagnostic
3427 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3428 The real bug is a race condition between Emacs and glib: Emacs
3429 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3430 so that glib can't find it. Work around the bug by invoking
3431 waitpid only on subprocesses that Emacs itself creates.
3432 * process.c (create_process, record_child_status_change):
3433 Don't use special value -1 in pid field, as the caller now must
3434 know the pid rather than having the callee infer it.
3435 The inference was sometimes incorrect anyway, due to another race.
3436 (create_process): Set new 'alive' member if child is created.
3437 (process_status_retrieved): New function.
3438 (record_child_status_change): Use it.
3439 Accept negative 1st argument, which means to wait for the
3440 processes that Emacs already knows about. Move special-case code
3441 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3442 processes that have already been waited for, by testing and
3443 clearing new 'alive' member.
3444 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3445 now does this internally.
3446 (handle_child_signal): Let record_child_status_change do all
3447 the work, since we do not want to reap all exited child processes,
3448 only the child processes that Emacs itself created.
3449 * process.h (Lisp_Process): New boolean member 'alive'.
3451 Omit duplicate definitions no longer needed with gcc -g3.
3452 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3453 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3454 Define only as macros. There's no longer any need to also define
3455 these symbols as enums or as constants, since we now assume
3456 gcc -g3 when debugging.
3458 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3460 * lisp.mk: Adjust comments to the fact that term/internal is now
3461 loaded from loadup.el.
3463 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3464 (msdos_fatal_signal): New function.
3465 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3468 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3469 for GCC versions before 4.
3470 (emacs_raise): Define to call msdos_fatal_signal.
3472 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3473 iterator when starting in the middle of a display or overlay
3476 2012-11-03 Chong Yidong <cyd@gnu.org>
3478 * process.c (wait_reading_process_output): Clean up the last
3481 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3483 * process.c (wait_reading_process_output): Avoid a race condition
3484 with SIGIO delivery (Bug#11536).
3486 2012-11-03 Chong Yidong <cyd@gnu.org>
3488 * buffer.c (cursor_type): Untabify docstring.
3490 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3492 * frame.h (struct frame): Drop can_have_scroll_bars member
3493 which is meaningless for a long time. Adjust comments.
3494 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3495 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3497 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3499 * window.c (decode_next_window_args): Update window arg after
3500 calling decode_live_window and so fix crash reported at
3501 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3502 by Juanma Barranquero <lekktu@gmail.com>.
3503 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3504 * font.c (Ffont_at): Likewise.
3506 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3508 * widget.c (resize_cb): New function.
3509 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3510 (EmacsFrameResize): Check if all is up to date before changing frame
3513 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3515 Implement backtrace output for fatal errors on MS-Windows.
3516 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3517 (BACKTRACE_LIMIT_MAX): New macro.
3518 (w32_backtrace): New function.
3519 (emacs_abort): Use w32_backtrace when the user chooses not to
3520 attach a debugger. Update the text of the abort dialog.
3522 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3524 Window-related stuff cleanup here and there.
3525 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3526 Use decode_any_window.
3527 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3528 * xdisp.c (Fformat_mode_line): Likewise.
3529 * font.c (Ffont_at): Use decode_live_window.
3530 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3531 * window.c (decode_next_window_args): Likewise.
3532 (decode_any_window): Remove static.
3533 * window.h (decode_any_window): Add prototype.
3534 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3535 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3538 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3540 Remove pad from struct input_event.
3541 * termhooks.h (struct input_event): Remove padding field.
3543 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3544 member is never cons for a long time. Adjust comment.
3545 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3546 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3547 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3548 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3550 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3552 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3554 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3556 Fix crash when using Emacs as commit editor for git (Bug#12697).
3557 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3558 and it is configured in conf_post.h.
3559 (Fcall_process): Don't invoke both setsid and setpgid; the former
3560 is enough, if it exists.
3561 * callproc.c (Fcall_process, child_setup):
3562 * process.c (create_process): Use setpgid.
3563 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3565 * dispnew.c (init_display): Initialize the foreground group
3566 if we are running a tty display.
3567 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3568 * lisp.h (init_foreground_group): New decl.
3569 * sysdep.c (inherited_pgroup): New static var.
3570 (init_foreground_group, tcsetpgrp_without_stopping)
3571 (narrow_foreground_group, widen_foreground_group): New functions.
3572 (init_sys_modes): Narrow foreground group.
3573 (reset_sys_modes): Widen foreground group.
3575 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3577 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3579 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3581 * minibuf.c (read_minibuf): Restore current buffer since
3582 choose_minibuf_frame calling Fset_frame_selected_window may
3583 change it (Bug#12766).
3585 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3587 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3589 2012-10-30 Kenichi Handa <handa@gnu.org>
3591 * font.c (Ffont_at): If WINDOW is specified and it is not
3592 displaying the current buffer, signal an error.
3594 2012-10-29 Daniel Colascione <dancol@dancol.org>
3596 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3597 In preparation for fixing bug#12739, move these functions from
3600 * coding.h, coding.c: ... to here, and compile them only when
3601 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3602 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3604 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3606 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3607 (timer_loop, getitimer, setitimer): Use it instead of
3608 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3610 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3613 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3615 * nsterm.m (NO_APPDEFINED_DATA): New define.
3616 (last_appdefined_event_data): New variable
3617 (last_appdefined_event): Remove.
3618 (ns_select): Initialize t from last_appdefined_event_data instead
3619 of [last_appdefined_event data1].
3620 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3621 remove last_appdefined_event (Bug#12698).
3623 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3625 * frame.c (x_set_font): Catch internal error.
3627 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3629 Avoid overflow in w32 implementation of interval timers.
3630 When possible, for ITIMER_PROF count only times the main thread
3632 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3633 'volatile ULONGLONG' types. All the other data which was
3634 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3635 (GetThreadTimes_Proc): New typedef.
3636 (w32_get_timer_time): New function, returns a suitable time value
3638 (timer_loop): Enter critical section when accessing ULONGLONG
3639 values of the itimer_data struct, as these accesses are no longer
3640 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3641 Remove unused variable.
3642 (init_timers): Initialize s_pfn_Get_Thread_Times.
3643 (start_timer_thread): Don't assign itimer->caller_thread here.
3644 (getitimer): Assign itimer->caller_thread here.
3645 (setitimer): Always call getitimer to get the value of ticks_now.
3646 (sys_spawnve): Avoid compiler warning about format mismatch.
3648 2012-10-26 Eli Zaretskii <eliz@gnu.org>
3650 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3651 mouse movement events if the menu bar is active. This avoids
3652 producing a busy "hour-glass" cursor by Windows if the mouse
3653 pointer is positioned over a tooltip shown for some menu item.
3655 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3657 Don't assume process IDs fit in int.
3658 * emacs.c (shut_down_emacs) [!DOS_NT]:
3659 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3660 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3661 Use pid_t, not int, to store process IDs, as 'int'
3662 is not wide enough on a few platforms (e.g., AIX and IRIX).
3664 2012-10-23 Kenichi Handa <handa@gnu.org>
3666 The following change is to make face-font-rescale-alist work
3667 correctly for non-ASCII fonts.
3669 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
3670 (font_open_for_lface): Handle Vface_font_rescale_alist.
3672 2012-10-23 Chong Yidong <cyd@gnu.org>
3674 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
3676 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
3678 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
3680 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
3682 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
3685 2012-10-21 Glenn Morris <rgm@gnu.org>
3687 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.

3692 * frame.c (Fmouse_position, Fmouse_pixel_position):
3693 * xdisp.c (produce_stretch_glyph):

4169 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4170 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
4171 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
4172 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
4173 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
4174 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4175 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4176 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4177 now a supported configuration.
4179 * Makefile.in: consolidate image variables into LIBIMAGE; add
4180 W32_OBJ and W32_LIBS. Compile new files.
4183 (_DebPrint) declare tracing facility for W32 debugging. We need
4184 to unify tracing later.
4186 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4187 unconditional use of W32 Unicode functions. Cygwin runs only on
4188 100% Unicode operating systems.
4190 * cygw32.c: New file. Define Cygwin-specific facilities.
4191 (Fcygwin_convert_path_to_windows)
4192 (Fcygwin_convert_path_from_windows): New user functions for
4193 accessing Cygwin path-munging routines.
4195 * cygw32.h: New file.
4196 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4197 UTF-16LE strings temporarily inside non-Lisp-visible string
4200 (w32_strerror): Just what it says on the tin.
4202 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4203 also run for Cygwin; both systems have the same problem with using
4204 GUI facilities in a forked child. Also call syms_of_cygw32,
4205 syms_of_w32select in correct places.
4207 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4208 needs fork-then-exec for daemon launching.
4210 * font.h: Include frame.h.
4212 * image.c: Use the image library cache machinery only when we're
4213 compiling for native WINDOWSNT; Cygwin can use shared libraries
4214 like any other Unixlike system.
4216 * keyboard.c: Clarify a comment regarding the input loop.
4218 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4219 functions directly instead of trying to detect at runtime that our
4220 host operating system supports them. We make this change for two
4221 reasons: Cygwin lacks support for the multibyte character
4222 conversion functions used by the legacy menu code, and Cygwin
4223 never needs to rely on non-Unicode APIs.
4225 * unexw32.c (hinst): Declare extern.
4227 * w32.c: Change header order;
4228 (w32_strerror): Move to w32fns.c because we need it for
4229 non-WINDOWSNT builds.
4231 * w32.h: Add #error macro to make sure we don't include w32.h for
4232 Cygwin builds. Remove w32select declarations.
4234 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4235 w32fns.c. w32console.c is WINDOWSNT-only.
4237 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4238 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4240 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4241 (w32_major_version, w32_minor_version, w32_build_number)
4242 (os_subtype, sound_type): Define here
4243 (w32_defined_color): Make color parameter const for consistency
4244 with other _defined_color functions.
4245 (w32_createwindow): Unconditionally call w32_init_class instead of
4246 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4247 through the code is complex and unnecessary because class
4248 registration is practically free.
4249 (w32_name_of_message): New EMACSDEBUG-only function.
4250 (Fset_message_beep): Move here
4251 (Fx_open_connection): Require that the display name for Windows be
4252 "w32" for consistency, emacsclient disambiguation, and maybe, one
4253 day, multi-window-system support.
4254 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4255 Cygwin files for W32 GUI facilities, since these clearly don't
4256 expect Cygwin names.
4257 (_DebPrint): Define.
4258 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4259 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4260 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4261 (w32_last_error): Remove.
4263 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4265 * w32heap.c (syspage_mask): Declare here.
4266 (cache_system_info): Remove.
4268 * w32inevt.c (faked_key): Define globally, not statically.
4269 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4270 (w32_console_toggle_lock_key): Move to w32fns.c.
4272 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4274 * w32proc.c (_DebPrint): Move to w32fns.c.
4275 * w32select.c: Include string.h, stdio.h for Cygwin.
4276 * w32select.h: New File.
4278 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4280 (w32_message_fd): New variable. Under Cygwin, holds the file
4281 descriptor the system used to tell us about pending thread
4284 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4285 that prevented compilation under non-WINDOWSNT systems.
4287 (w32_initialize): Open /dev/windows and assign it to
4288 w32_message_fd. Provide w32 feature.
4290 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4291 (WM_EMACS_INPUT_READY): add.
4292 (prepend_msg, w32_message_fd): Declare globally.
4295 (keyboard_handle): Use only when WINDOWSNT.
4296 (notify_msg_ready): New function. Posts a message to the main
4297 thread's message queue under CYGWIN, which wakes up the main
4298 thread from select(2) by making the /dev/windows file descriptor
4299 ready. Under WINDOWSNT, it sets an event the same way the old
4302 (post, prepend_msg): Actually call notify_msg_ready instead of
4303 setting the input event directly.
4305 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4307 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4308 but it still has blocs in it, don't return it to the system,
4309 instead of aborting. (Bug#12402)
4311 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4313 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4315 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4316 MAC_OS_X_VERSION_10_6.
4317 (syms_of_nsterm): Remove comment about Panther and above for
4319 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
4320 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
4321 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4323 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4324 MAC_OS_X_VERSION_10_4.
4326 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4327 MAC_OS_X_VERSION_10_2.
4329 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4331 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4332 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4334 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4335 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4336 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4337 Remove ns_in_resize check.
4338 (ns_clear_frame_area): Remove resize handle code.
4340 * nsfns.m (ns_in_resize): Remove.
4341 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4342 Remove ns_in_resize check.
4344 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4346 Improve sys_siglist detection.
4347 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4348 defined as a macro, as is done in Solaris.
4349 (sys_siglist_entries): New macro.
4350 (save_strsignal): Use it.
4351 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4352 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4354 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4356 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4357 fullscreen/Fullscreen.
4359 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4360 tobar_height is new.
4362 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4363 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4364 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4365 (windowDidResize:): Check for correct window if old style fullscreen.
4366 Capitalize word in comment. Remove incorrect comment.
4367 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4368 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4369 error in drawing background.
4370 (toggleFullScreen:): Remove comment. Rearrange calls.
4371 Set toolbar values to zero, save old height in tobar_height.
4372 Restore tool bar height when leaving fullscreen.
4373 (canBecomeMainWindow): New function.
4375 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4377 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4379 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4381 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4383 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4384 that time stamps of directories could also be changed.
4385 Don't request the too broad GENERIC_WRITE, only the more restrictive
4386 FILE_WRITE_ATTRIBUTES access rights.
4388 * fileio.c (Fset_file_times): Special-case ignoring errors for
4389 directories only on MSDOS, not on MS-Windows.
4391 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4393 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4395 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4397 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4398 see whether CreateFile failed.
4400 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4402 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4403 to avoid similar races.
4404 * keyboard.c (pending_signals): Now bool, not int.
4406 Port timers to OpenBSD, plus check for timer failures.
4407 OpenBSD problem reported by Han Boetes.
4408 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4410 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4411 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4412 like OpenBSD, which has timer_settime but does not declare it.
4413 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4414 whether to use itimerspec-related primitives. All uses of
4415 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4417 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4419 * profiler.c (handle_profiler_signal): Fix a malloc race
4420 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4422 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4424 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4426 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4428 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4429 consistent with the change in return value of 'safe_strsignal'.
4431 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4433 Prefer plain 'static' to 'static inline' (Bug#12541).
4434 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4435 (bidi_set_sor_type, bidi_push_embedding_level)
4436 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
4437 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
4438 (bidi_cache_search, bidi_cache_ensure_space)
4439 (bidi_cache_iterator_state, bidi_cache_find)
4440 (bidi_peek_at_next_level, bidi_set_paragraph_end)
4441 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4442 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4443 Now 'static', not 'static inline'.
4445 Count overruns when profiling; change units to ns.
4446 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4447 Give extra weight to samples after overruns, to attempt to count
4448 the time more accurately.
4449 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4450 the underlying primitives nominally do ns.
4451 (Fprofiler_cpu_start): Document the change. Mention that
4452 the sampling intervals are only approximate.
4454 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4456 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4458 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4459 case for the special 0 coding-system.
4461 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4462 (Fmake_overlay): Remove redundant tests.
4463 (fix_start_end_in_overlays): Remove redundant recentering.
4465 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4467 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4468 Update dependencies.
4470 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4472 Fix a malloc race condition involving strsignal.
4473 A signal can arrive in the middle of a malloc, and Emacs's signal
4474 handler can invoke strsignal, which can invoke malloc, which is
4475 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4476 Fix it by altering the signal handler so that it does not invoke
4478 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4479 * process.c (status_message): Use const pointer, in case strsignal
4480 is #defined to safe_strsignal.
4481 * sysdep.c (sys_siglist, init_signals): Always define and
4482 initialize a substitute sys_siglist if the system does not define
4483 one, even if HAVE_STRSIGNAL.
4484 (safe_strsignal): Rename from strsignal. Always define,
4485 using sys_siglist. Return a const pointer.
4486 * syssignal.h (safe_strsignal): New decl.
4487 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4489 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4491 * w32proc.c (timer_loop): Fix code that waits for timer
4492 expiration, to avoid high CPU usage.
4494 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4496 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4497 (sweep_weak_table): Remove redundant prototypes.
4499 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4501 * emacs.c: Move the inclusion of TERM_HEADER after including
4502 windows.h on WINDOWSNT. This avoids compilation problems with
4505 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4507 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4508 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4509 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4510 as the previous version used 'void *'.
4512 * ralloc.c (ROUNDUP): Fix last change.
4513 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4516 * w32proc.c <disable_itimers>: New static flag.
4517 (init_timers): Initialize it to zero, after creating the critical
4518 sections used by the timer threads.
4519 (term_timers): Set to 1 before deleting the critical sections.
4520 (getitimer, setitimer): If disable_itimers is non-zero, return an
4521 error indication without doing anything. Reported by Fabrice
4522 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4523 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4525 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4528 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4529 term_ntproc after all the other bookkeeping, to get timers working
4530 as long as possible.
4532 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4534 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4535 Suggested by Juri Linkov in
4536 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4538 Prefer plain 'static' to 'static inline' (Bug#12541).
4539 With static functions, modern compilers inline pretty well by
4540 themselves; advice from programmers often hurts as much as it helps.
4541 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4542 this change shrinks the text size of the Emacs executable by 1.1%
4543 without affecting CPU significantly in my benchmark.
4544 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

4629 * dired.c (directory_files_internal, Ffile_attributes):
4632 * frame.c (x_report_frame_params): Port better to wider ints.
4633 Do not assume that EMACS_UINT is the same width as uprintmax_t,

4837 (handle_profiler_signal): Rename from sigprof_handler_1,
4838 for consistency with other handlers. Do not check whether
4839 cpu_log is a hash-table if garbage collecting, since it

4842 for consistency with other handlers.
4843 (setup_cpu_timer): New function, with much of what used to be in

4845 Prefer timer_settime if available, and prefer
4846 thread cputime clocks, then process cputime clocks, then
4847 monotonic clocks, to the old realtime clock. Use make_timeval
4848 to round more-correctly when falling back to setitimer.
4849 (Fprofiler_cpu_start): Use it.
4850 (Fprofiler_cpu_stop): Prefer timer_settime if available.

4917 Since this stuff is now private to charset.c, there's no need for
4918 a public macro and no need to inline by hand.

5069 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
5070 (interruptible_wait_for_termination):
5071 Move these decls from lisp.h to syswait.h, since they use pid_t.
5072 Needed on FreeBSD; see Herbert J. Skuhra in
5073 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
5074 * callproc.c: Include syswait.h.
5076 gnutls.c, gtkutil.c: Use bool for boolean.
5077 * gnutls.c (gnutls_global_initialized, init_gnutls_functions)
5078 (emacs_gnutls_handle_error):
5079 * gtkutil.c (xg_check_special_colors, xg_prepare_tooltip)

5089 (update_frame_tool_bar, free_frame_tool_bar):
5090 * gtkutil.c, w32term.c, xterm.c (x_wm_set_size_hint):
5091 * nsmenu.m (ns_update_menubar):
5092 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
5093 * xfns.c (Fx_show_tip) [USE_GTK]:
5094 Use bool for boolean.
5095 * gtkutil.c (xg_update_frame_menubar):
5096 * xmenu.c (update_frame_menubar):
5097 Return void, not int, since caller ignores return value.
5098 * gtkutil.c (xg_change_toolbar_position):
5101 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5103 * makefile.w32-in (BLOCKINPUT_H): Remove.
5104 (SYSSIGNAL_H): New macro.

5120 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5122 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5123 fatal_error_backtrace.
5125 * w32proc.c (sys_kill): Undo last change: don't do anything when
5126 invoked to deliver SIGABRT to our own process. This is now
5127 handled by emacs_raise.
5129 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5131 * w32term.c (w32_read_socket): Remove leftover reference to
5132 interrupt_input_pending.
5134 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5136 Do not use SA_NODEFER.
5137 Problem reported by Dani Moncayo in
5138 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5140 * sysdep.c (emacs_abort): Do not reset signal handler.
5141 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5142 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5143 wanted even on POSIXish hosts, and it doesn't work on Windows.
5145 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5147 * xterm.c (x_term_init): Call fixup_locale before and after calling
5148 gtk_init (Bug#12392).
5150 2012-09-23 Chong Yidong <cyd@gnu.org>
5152 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5153 Vdynamic_library_alist.
5155 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5156 (Fgnutls_available_p): Caller changed.
5158 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5159 (Flibxml_parse_xml_region): Likewise.
5161 * dispextern.h (struct image_type): Remove arg from init function.
5163 * image.c (Finit_image_library, lookup_image_type)
5164 (define_image_type): Remove now-unneeded second arg.
5165 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5166 (init_tiff_functions, init_gif_functions, init_svg_functions):
5167 Arglist and w32_delayed_load calling convention changed.
5168 (gs_type): Remove init_gs_functions; there is no such function.
5169 (valid_image_p, make_image): Fix caller to lookup_image_type.
5171 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5173 Simplify and avoid signal-handling races (Bug#12471).
5175 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5176 Avoid recursive loop if there's a fatal error in the function itself.
5177 * atimer.c (pending_atimers):
5178 * blockinput.h: Don't include "atimer.h"; no longer needed.
5179 (interrupt_input_pending): Remove. All uses removed.
5180 pending_signals now counts both atimers and ordinary interrupts.
5181 This is less racy than having three separate pending-signal flags.
5182 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5184 Rename from their upper-case counterparts BLOCK_INPUT,
5185 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5186 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5187 This makes it easier to access volatile variables more accurately.
5188 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5189 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5190 that's more reliable if the code is buggy and sets
5191 interrupt_input_blocked to a negative value. All uses changed.
5192 * atimer.c (deliver_alarm_signal):
5193 Remove. No need to deliver this to the parent; any thread can
5194 handle this signal now. All uses replaced by underlying handler.
5195 * atimer.c (turn_on_atimers):
5196 * dispnew.c (handle_window_change_signal):
5197 * emacs.c (handle_danger_signal):
5198 * keyboard.c (kbd_buffer_get_event):
5199 Don't reestablish signal handler; not needed with sigaction.
5200 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5202 Rework to avoid unnecessary accesses to volatile variables.
5203 (UNBLOCK_INPUT_TO): Now a function.
5204 (totally_unblock_input, unblock_input): New decls.
5205 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5206 (init_data): Remove. Necessary stuff now done in init_signal.
5207 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5208 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5209 (fatal_error_code): Remove; no longer needed.
5210 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5211 it doesn't always backtrace. All uses changed. No need to reset
5212 signal to default, since sigaction and/or die does that for us now.
5213 Use emacs_raise (FOO), not kill (getpid (), FOO).
5214 (main): Check more-accurately whether we're dumping.
5215 Move fatal-error setup to sysdep.c
5216 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5217 * gtkutil.c (xg_get_file_name, xg_get_font):
5218 Remove no-longer-needed signal-mask manipulation.
5219 * keyboard.c, process.c (POLL_FOR_INPUT):
5220 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5221 * keyboard.c (read_avail_input): Remove.
5222 All uses replaced by gobble_input.
5223 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5224 (kbd_buffer_store_event_hold, gobble_input):
5225 (record_asynch_buffer_change) [USABLE_SIGIO]:
5226 (store_user_signal_events):
5227 No need to mess with signal mask.
5228 (gobble_input): If blocking input and there are terminals, simply
5229 set pending_signals to 1 and return. All hooks changed to not
5230 worry about whether input is blocked.
5231 (process_pending_signals): Clear pending_signals before processing
5232 them, in case a signal comes in while we're processing.
5233 By convention callers now test pending_signals before calling us.
5234 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5235 New functions, to support changes to blockinput.h.
5236 (handle_input_available_signal): Now extern.
5237 (reinvoke_input_signal): Remove. All uses replaced by
5239 (quit_count): Now volatile, since a signal handler uses it.
5240 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5241 All callers changed. Block SIGINT only if not already blocked.
5242 Clear sigmask reliably, even if Fsignal returns, which it can.
5243 Omit unnecessary accesses to volatile var.
5244 (quit_throw_to_read_char): No need to restore sigmask.
5245 * keyboard.c (gobble_input, handle_user_signal):
5246 * process.c (wait_reading_process_output):
5247 Call signal-handling code rather than killing ourselves.
5248 * lisp.h: Include <float.h>, for...
5249 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5250 (pending_signals): Now volatile.
5251 (syms_of_data): Now const if IEEE floating point.
5252 (handle_input_available_signal) [USABLE_SIGIO]:
5253 (terminate_due_to_signal, record_child_status_change): New decls.
5254 * process.c (create_process): Avoid disaster if memory is exhausted
5255 while we're processing a vfork, by tightening the critical section
5257 (send_process_frame, process_sent_to, handle_pipe_signal)
5258 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5260 (send_process): No need for setjmp/longjmp any more, since the
5261 SIGPIPE stuff is now gone. Instead, report an error if errno
5263 (record_child_status_change): Now extern. PID and W are now args.
5264 Return void, not bool. All callers changed.
5265 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5266 Remove. All uses removed. This bug should be fixed now in a
5268 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5269 and record the child status change directly. This avoids the
5270 need to futz with the signal mask.
5271 (process_fatal_action): Move here from emacs.c.
5272 (emacs_sigaction_flags): New function, containing
5273 much of what used to be in emacs_sigaction_init.
5274 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5275 caught by emacs, to make races less likely.
5276 (deliver_process_signal): Rename from handle_on_main_thread.
5278 (BACKTRACE_LIMIT_MAX): Now at top level.
5279 (thread_backtrace_buffer, threadback_backtrace_pointers):
5281 (deliver_thread_signal, deliver_fatal_thread_signal):
5282 New functions, for more-accurate delivery of thread-specific signals.
5283 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5284 (deliver_arith_signal): Handle in this thread, not
5285 in the main thread, since it's triggered by this thread.
5286 (maybe_fatal_sig): New function.
5287 (init_signals): New arg DUMPING so that we can be more accurate
5288 about whether we're dumping. Caller changed.
5289 Treat thread-specific signals differently from process-general signals.
5290 Block all signals while handling fatal error; that's safer.
5291 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5293 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5294 Ignore SIGPIPE unless batch.
5295 (emacs_backtrace): Output backtrace for the appropriate thread,
5296 which is not necessarily the main thread.
5297 * syssignal.h: Include <stdbool.h>.
5298 (emacs_raise): New macro.
5299 * xterm.c (x_connection_signal): Remove; no longer needed
5300 now that we use sigaction.
5301 (x_connection_closed): No need to mess with sigmask now.
5302 (x_initialize): No need to reset SIGPIPE handler here, since
5303 init_signals does this for us now.
5305 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5307 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5308 background rect may be larger (Bug#12245).
5310 2012-09-23 Chong Yidong <cyd@gnu.org>
5312 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5314 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5316 * .gdbinit: Just stop at fatal_error_backtrace.
5317 See Stefan Monnier's request in
5318 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5319 Remove no-longer-used query of system type.
5321 2012-09-22 Chong Yidong <cyd@gnu.org>
5323 * search.c (Freplace_match): Doc fix (Bug#12325).
5325 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5327 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5328 (Fline_end_position): Doc fix.
5330 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5332 2012-09-22 Chong Yidong <cyd@gnu.org>
5334 * dispextern.h (struct image_type): Add new slot, storing a type
5335 initialization function.
5337 * image.c (define_image_type): Call the image initializer function
5338 if it is defined. Arguments and return value changed.
5339 (valid_image_p, make_image): Callers changed.
5340 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5341 (gif_type, imagemagick_type, svg_type, gs_type):
5342 Add initialization functions.
5343 (Finit_image_library): Call lookup_image_type.
5344 (CHECK_LIB_AVAILABLE): Macro deleted.
5345 (lookup_image_type): Call define_image_type here, rather than via
5346 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5347 (syms_of_image): Move define_image_type calls for xbm_type and
5348 pbm_type to lookup_image_type.
5350 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5352 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5353 'idle_timers' from here ...
5354 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5355 lists, to avoid infloops when the timer does something stupid,
5356 like reinvoke itself with the same or smaller time-out.
5359 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5361 * window.c (Fsplit_window_internal): Handle only Qt value of
5362 Vwindow_combination_limit separately.
5363 (Qtemp_buffer_resize): New symbol.
5364 (Vwindow_combination_limit): New default value.
5367 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5369 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5370 the new overlay string. (Bug#10159)
5372 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5374 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5375 or that fprintf is async-signal-safe. POSIX doesn't require
5378 2012-09-22 Chong Yidong <cyd@gnu.org>
5380 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5383 2012-09-22 Kenichi Handa <handa@gnu.org>
5385 * composite.c (composition_reseat_it): Handle the case that a
5386 grapheme cluster is not covered by a single font (Bug#12352).
5388 2012-09-21 Chong Yidong <cyd@gnu.org>
5390 * image.c (define_image_type): Avoid adding duplicate types to
5391 image_types (Bug#12463). Suggested by Jörg Walter.
5393 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5395 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5396 (print_load_command_name): Add case LC_DATA_IN_CODE.
5397 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5399 2012-09-21 Glenn Morris <rgm@gnu.org>
5401 * eval.c (Frun_hook_with_args_until_success)
5402 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5404 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5406 * fileio.c (Ffile_selinux_context): Only call freecon when
5407 lgetfilecon succeeded.
5408 (Fset_file_selinux_context): Likewise. (Bug#12444)
5410 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5412 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5413 reordering, locate the cursor by calling set_cursor_from_row; if
5414 that fails, clear the desired glyph matrix before returning a
5415 failure indication to the caller. Fixes leaving garbled display
5416 when fast scrolling with a down-key. (Bug#12403)
5417 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5418 scrolling through multibyte text.
5420 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5422 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5423 calling mark_vectorlike since that's the one that marks the window.
5424 (mark_discard_killed_buffers): Mark the final cdr.
5425 * window.h (struct window): Move prev/next_buffers to the
5426 non-standard fields.
5427 * window.c (make_window): Initialize prev/next_buffers manually.
5429 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5431 Omit unused arg EXPECTED from socket hooks.
5432 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5433 * nsterm.m (ns_term_init):
5434 * termhooks.h (struct terminal.read_socket_hook):
5435 * w32inevt.c (w32_console_read_socket):
5436 * w32term.c (w32_read_socket):
5437 * xterm.c (XTread_socket):
5438 Omit unused arg EXPECTED. All callers changed.
5439 (store_user_signal_events): Return void, not int, since callers no
5440 longer care about the return value. All uses changed.
5442 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5444 * w32gui.h (XParseGeometry): Do not declare.
5446 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5448 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5449 Ignore 'expected'. See Eli Zaretskii in
5450 <http://bugs.gnu.org/12471#8> (last line).
5452 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5453 (XParseGeometry): Now static. Substitute extremal values for
5454 values that are out of range.
5456 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5458 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5460 * nsfns.m (XParseGeometry): Remove.
5461 (Fx_create_frame): Call x_set_offset to correctly interpret
5462 top_pos in geometry.
5464 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5465 (Fx_parse_geometry): If there is a space in string, call
5466 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5468 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5470 * search.c (scan_buffer): Use character positions in calls to
5471 region_cache_forward and region_cache_backward, not byte
5472 positions. (Bug#12196)
5474 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5475 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5477 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5478 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5479 emacs_blocked_malloc, now deleted.
5481 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5483 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5484 The workaround was for improving performance on Solaris 2.4, but
5485 is getting in the way now. Emacs will still work if someone is
5486 still running Solaris 2.4 in a museum somewhere; Sun dropped
5487 support for Solaris 2.4 in 2003.
5488 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5489 * process.c (create_process) [HAVE_WORKING_VFORK]:
5490 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5491 since Emacs no longer uses vfork on that platform.
5493 2012-09-17 Glenn Morris <rgm@gnu.org>
5495 * emacs.c: Use COPYRIGHT.
5497 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5499 Remove configure's --without-sync-input option (Bug#12450).
5500 When auditing signal-handling in preparation for cleaning it up,
5501 I found that SYNC_INPUT has race conditions and would be a real
5502 pain to fix. Since it's an undocumented and deprecated
5503 configure-time option, now seems like a good time to remove it.
5504 Also see <http://bugs.gnu.org/11080#16>.
5505 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5506 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5507 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5508 (malloc_hysteresis):
5509 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5510 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5511 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5512 (dont_register_blocks, bytes_used_when_reconsidered)
5513 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5514 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5515 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5516 Remove. All uses removed.
5517 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5518 implementation, one that depends on whether the new macro
5519 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5521 * atimer.c (run_timers, handle_alarm_signal):
5522 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5523 (handle_async_input, process_pending_signals)
5524 (handle_input_available_signal, init_keyboard):
5525 * nsterm.m (ns_read_socket):
5526 * process.c (wait_reading_process_output):
5527 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5528 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5530 * xterm.c (XTread_socket):
5532 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5533 * eval.c (handling_signal): Remove. All uses removed.
5534 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5535 All uses replaced with the SYNC_INPUT version.
5536 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5538 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5541 * font.c (Ffont_shape_gstring): Remove unused local.
5543 2012-09-16 Glenn Morris <rgm@gnu.org>
5545 * Makefile.in (clean): No longer run nextstep's clean.
5547 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5549 (ns-app): Move here from ns.mk, and simplify.
5550 (clean): Simplify nextstep entry.
5551 * ns.mk: Remove file.
5553 2012-09-17 Kenichi Handa <handa@gnu.org>
5555 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5556 not covert the last few charactes.
5558 2012-09-16 Kenichi Handa <handa@gnu.org>
5560 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5561 here, but just check the validity of glyphs in the glyph-string.
5563 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5565 * window.c (Fwindow_parameter, Fset_window_parameter):
5566 Accept any window as argument (Bug#12452).
5568 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5570 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5571 to ns_term_init to avoid memory leak.
5573 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5574 explicit retain/release.
5575 (ns_term_init): Only allow one display. Initialize outerpool and
5578 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5580 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5581 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5582 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5583 the Microsoft problem in a different way, by altering ../nt/config.nt.
5585 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5600 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5601 by lisp.h. This completes removal of setjmp.h inclusion
5602 erroneously announced in the previous commit. (Bug#12446)
5604 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5607 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5608 not defined as a macro. The latter happens on MS-Windows.
5611 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5613 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5614 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5615 Some instances of '#include <setjmp.h>' removed, if the
5616 only reason for the instance was because "lisp.h" was included.
5617 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5618 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5619 and _longjmp with the new symbols. Emacs already uses _setjmp if
5620 available, so this change affects only POSIXish hosts that have
5621 sigsetjmp but not _setjmp, such as some versions of Solaris and
5622 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5623 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5624 (png_load_body) [HAVE_PNG]:
5625 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5626 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5627 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5628 since PNG requires jmp_buf. This is the only exception to the
5629 general rule that we now use sys_setjmp and sys_longjmp.
5630 This exception is OK since this code does not change the signal
5631 mask or longjmp out of a signal handler.
5633 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5635 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5636 Include "syssignal.h", for 'main_thread'.
5638 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5640 Avoid out-of-range marker position (Bug#12426).
5641 * insdel.c (replace_range, replace_range_2):
5642 Adjust markers before overlays, as suggested by comments.
5643 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5644 Remove redundant check before calling offset_intervals.
5646 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5648 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5649 current buffer (Bug#12387).
5651 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5653 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5655 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5657 Use a more backwards-compatible timer format (Bug#12430).
5658 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5659 vector element, not from the 4th, since PSECS is now at the end.
5660 (Fcurrent_idle_time): Doc fix.
5662 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5664 Function to mark objects and remove killed buffers at once.
5665 * alloc.c (discard_killed_buffers): Rename to ...
5666 (mark_discard_killed buffers) ... new name. Add marking
5667 of remaining objects. Fix comment. Adjust users.
5668 (mark_object): Do not touch frame buffer lists here.
5669 * frame.c (delete_frame): Reset frame buffer lists here.
5671 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5673 Better workaround for GNOME bug when --enable-gcc-warnings.
5674 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5675 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5676 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5678 Simplify SIGIO usage (Bug#12408).
5679 The code that dealt with SIGIO was crufty and confusing, e.g., it
5680 played tricks like "#undef SIGIO" but these tricks were not used
5681 consistently. Simplify mostly by not #undeffing standard symbols,
5682 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5683 or not as we please) rather than "defined SIGIO" (standard symbol
5684 that we probably shouldn't #undef).
5685 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5686 Modules that need it can include it.
5687 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5688 * dispextern.h (ignore_sigio): New decl.
5689 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5690 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5691 * emacs.c (shut_down_emacs):
5692 * keyboard.c (kbd_buffer_store_event_hold):
5693 Use ignore_sigio rather than invoking 'signal' directly.
5694 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5696 (FIONREAD, SIGIO): Do not #undef.
5697 (tty_read_avail_input): Use #error rather than a syntax error.
5698 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5699 for I_PIPE, used by SETUP_SLAVE_PTY.
5700 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5701 * sysdep.c (croak): Remove; no longer needed. This bit of
5702 temporary code, with Fred N. Fish's comment that it's temporary,
5703 has been in Emacs since at least 1992!
5704 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5705 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5706 * syssignal.h (croak): Remove decl.
5707 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5708 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5709 now that we're termios-only.
5710 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5711 * term.c (dissociate_if_controlling_tty): Use #error rather than
5714 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5715 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5716 to work around GNOME bug 683906.
5717 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5718 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5719 This works around GCC bug 54561.
5721 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5723 More fixes for 'volatile' and setjmp/longjmp.
5724 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5725 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5726 (png_load_body) [HAVE_PNG]:
5727 (jpeg_load_body) [HAVE_JPEG]:
5728 New function, with most of the old parent function's body.
5729 (png_load) [HAVE_PNG]:
5730 (jpeg_load) [HAVE_JPEG]:
5731 Invoke the new function, to avoid longjmp munging our locals.
5732 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5733 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5734 longjmp is passed 2, as the C standard doesn't guarantee this.
5735 Instead, store the failure code into mgr->failure_code.
5737 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5739 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5740 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5741 (syms_of_keyboard): Remove support for unread-command-char.
5743 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5745 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5746 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5747 violation. (Bug#12426)
5749 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5751 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5753 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5755 * eval.c: Add `inhibit-debugger'.
5756 (Qinhibit_debugger): New symbol.
5757 (call_debugger): Bind it instead of Qdebug_on_error.
5758 (maybe_call_debugger): Test Vinhibit_debugger.
5759 (syms_of_eval): Define inhibit-debugger.
5760 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5761 (syms_of_xdisp): Remove inhibit-debug-on-message.
5763 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5765 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5766 If a nonvolatile local variable is written before a _longjmp to
5767 the frame containing the variable, and is read after the _longjmp,
5768 the value read is indeterminate. Some local variables of type
5769 'struct handler' and 'struct catchtag' are used in this way, so
5770 mark each of their slots as volatile if the slot can be set before
5771 _longjmp and read afterwards.
5772 * lisp.h (struct handler): var and chosen_clause are now volatile.
5773 (struct catchtag): val, next, and pdlcount are now volatile.
5775 * bidi.c (bidi_push_it, bidi_pop_it):
5776 * fns.c (copy_hash_table):
5777 * image.c (define_image_type):
5778 * keyboard.c (kbd_buffer_store_event_hold):
5779 * process.c (Fprocess_send_eof):
5780 * xfaces.c (x_create_gc) [HAVE_NS]:
5781 * xgselect.c (xg_select):
5782 Prefer assignment to memcpy when either will do.
5784 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5785 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5786 time an item is removed. No need to mark this function 'inline';
5787 the compiler knows better than we do.
5789 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5791 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5792 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5793 to change_frame_size (Bug#12388).
5794 (windowDidResize:): Pass YES to updateFrameSize.
5796 * nsterm.h: Add delay parameter to updateFrameSize.
5798 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5800 Discard killed buffers from deleted window and frame objects.
5801 This reduces an amount of references to killed buffers and
5802 helps GC to reclaim them faster.
5803 * alloc.c (discard_killed_buffers): New function.
5804 (mark_object): Use it for deleted windows and frames.
5805 (mark_object): If symbol's value is set up for a killed buffer
5806 or deleted frame, restore its global binding.
5807 * data.c (swap_in_global_binding): Add GC notice.
5808 (swap_in_symval_forwarding): Use convenient set_blv_where.
5809 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5810 * window.h: ... to here.
5812 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5814 Convenient macro to check whether the buffer is live.
5815 * buffer.h (BUFFER_LIVE_P): New macro.
5816 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5817 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5819 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5821 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5822 composition cases (Bug#12364).
5824 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5825 overhang of succeeding glyphs overlapping box cursor.
5827 * w32term.c (x_draw_glyph_string): Likewise.
5829 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5831 Simplify, document, and port floating-point (Bug#12381).
5832 The porting part of this patch fixes bugs on non-IEEE platforms
5833 with frexp, ldexp, logb.
5834 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5836 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5837 support, by removing commented-out code and briefly listing the
5838 C89 functions excluded. The commented-out stuff was confusing
5839 maintenance, e.g., we thought we needed cbrt but it was commented out.
5840 (logb): Remove decl; no longer needed.
5841 (isfinite): New macro, if not already supplied.
5842 (isnan): Don't replace any existing macro.
5843 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5844 are present on all C89 platforms.
5845 (Ffrexp): Do not special-case zero, as frexp does the right thing
5847 (Flogb): Do not use logb, as it doesn't have the desired meaning
5848 on hosts that use non-base-2 floating point. Instead, stick with
5849 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5850 frexp, to avoid getting an unspecified result.
5852 * xdisp.c (Qinhibit_debug_on_message): Now static.
5854 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5856 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5857 NSBezierPath (Bug#12131).
5859 2012-09-10 Chong Yidong <cyd@gnu.org>
5861 * fns.c (Fdelq, Fdelete): Doc fix.
5863 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5865 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5866 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5868 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5870 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5871 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5874 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5876 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5877 left fringe if the window has a left margin. This avoids leaving
5878 traces of the cursor because its leftmost pixel is not drawn over.
5880 * dispnew.c (update_window_line): When the left margin area of a
5881 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5882 that screen line. (Bug#12277)
5884 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5886 Assume C89 or later for math functions (Bug#12381).
5887 This simplifies the code, and makes it a bit smaller and faster,
5888 and (most important) makes it easier to clean up signal handling
5889 since we can stop worring about floating-point exceptions in
5890 library code. That was a problem before C89, but the problem
5891 went away many years ago on all practical Emacs targets.
5892 * data.c, image.c, lread.c, print.c:
5893 Don't include <math.h>; no longer needed.
5894 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5895 might be autoconfigured, as that never happens.
5897 * doprnt.c (DBL_MAX_10_EXP):
5898 * print.c (DBL_DIG):
5899 Remove. C89 or later always defines these.
5900 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5901 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5902 (arith_error, domain_error, domain_error2):
5903 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5904 no longer needed -- we simply return what C returns. All uses removed.
5905 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5907 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5908 Remove. All uses expanded, as these macros are no longer used
5909 more than once and are now more trouble than they're worth.
5910 (Ftan): Use tan, not sin / cos.
5911 (Flogb): Assume C89 frexp.
5912 (fmod_float): Assume C89 fmod.
5913 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5914 (init_floatfns): Remove. All uses removed.
5916 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5918 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5919 compositeToPoint for OSX < 10.6 (Bug#12390).
5921 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5923 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5924 This produces more-accurate results.
5926 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5928 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5929 changes (Bug#12088).
5931 2012-09-08 Chong Yidong <cyd@gnu.org>
5933 * syntax.c (Fstring_to_syntax): Doc fix.
5935 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5937 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5938 in the internal border.
5939 (x_set_window_size): Remove static variables and their usage.
5940 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5941 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5942 Remove fringe/internal border adjustment (Bug#11052).
5943 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5944 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5945 (ns_fix_rect_ibw): Remove.
5946 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5947 (ns_dumpglyphs_box_or_relief): Ditto.
5948 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5950 (ns_dumpglyphs_image): Ditto.
5951 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5953 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5954 their usage. Add fringe_extended_p and its use as in other terms.
5955 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5956 scroll bar was removed.
5957 (updateFrameSize): New function.
5958 (windowDidResize): Move code to updateFrameSize and call it.
5960 * nsterm.h (EmacsView): Add updateFrameSize.
5962 2012-09-07 Chong Yidong <cyd@gnu.org>
5964 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5966 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5968 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5970 More signal-handler cleanup (Bug#12327).
5971 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5972 Problem introduced when merging patches. Noted by Eli Zaretskii in
5973 <http://bugs.gnu.org/12327#67>.
5974 * floatfns.c: Comment fix.
5975 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5976 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5977 and anyway the declaration is harmless even if SIGDANGER is not defined.
5978 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5979 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5980 source files not surprisingly expected syssignal.h to define, or
5981 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5982 Include <sys/ioctl.h>, for FIONREAD.
5983 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5984 This eliminates a problem whereby other files mysteriously had
5985 to include "syssignal.h" before including "systty.h" if they
5986 wanted to use "#ifdef SIGIO".
5988 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5990 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5992 * w32.c (sigemptyset): Empty the set.
5993 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5995 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5997 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5999 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6000 (mark_object): Likewise for frame objects.
6002 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6004 * syssignal.h (handle_on_main_thread): Always declare,
6005 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6006 This ports to platforms without HAVE_PTHREAD.
6008 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6010 Signal-handler cleanup (Bug#12327).
6011 Emacs's signal handlers were written in the old 4.2BSD style with
6012 sigblock and sigmask and so forth, and this led to some
6013 inefficiencies and confusion. Rewrite these to use
6014 pthread_sigmask etc. without copying signal sets around. Also,
6015 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6016 'signal', and instead use functions that do not attempt to take
6017 over the system name space. This patch causes Emacs's text
6018 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6019 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6020 Do not include <signal.h> or "syssignal.h", as these
6021 modules do not use signals.
6022 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6023 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6024 Do not include <signal.h>, as "syssignal.h" does that for us now.
6025 * atimer.c (sigmask_atimers): New function.
6026 (block_atimers, unblock_atimers): New functions,
6027 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6029 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6030 no longer needed here.
6031 * emacs.c (main): Inspect existing signal handler with sigaction,
6032 so that there's no need to block and unblock SIGHUP.
6033 * sysdep.c (struct save_signal): New member 'action', replacing
6034 old member 'handler'.
6035 (save_signal_handlers, restore_signal_handlers):
6036 Use sigaction instead of 'signal' to save and restore.
6037 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6038 New function. All users of 'signal' modified to use set_sighandler
6039 if they're writeonly, and to use sys_signal if they're read+write.
6040 (emacs_sigaction_init, forwarded_signal): New functions.
6041 (sys_signal): Remove. All uses replaced by calls to sigaction
6042 and emacs_sigaction_init, or by direct calls to 'signal'.
6043 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6044 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6045 all uses replaced by pthread_sigmask etc. calls.
6046 * syssignal.h: Include <signal.h>.
6047 (emacs_sigaction_init, forwarded_signal): New decls.
6048 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6049 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6050 (sigmask, sys_sigmask): Remove; no longer needed.
6051 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6052 (sigblock, sigunblock, sigfree):
6053 (sigsetmask) [!defined sigsetmask]:
6054 Remove. All uses replaced by pthread_sigmask.
6055 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6056 no longer need to be replaced, and its typical old uses
6057 are now done via emacs_sigaction_init and sigaction.
6058 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6059 (sys_sigdel): Remove; unused.
6060 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6062 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6064 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6065 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6067 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6069 Explicitly mark buffer_defaults and buffer_local_symbols.
6070 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6071 mark_local_symbols here.
6072 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6073 since special buffers aren't marked here any more.
6074 (allocate_buffer): Chain new buffer with all_buffers here...
6075 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6077 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6078 (syms_of_buffer): Remove staticpro of the above.
6079 (init_buffer_once): Set names for buffer_defaults and
6080 buffer_local_symbols.
6082 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6084 Use bool for booleans in font-related modules.
6085 * font.c (font_intern_prop, font_style_to_value)
6086 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6087 (generate_otf_features, font_check_otf_features, font_check_otf)
6088 (font_match_p, font_list_entities, font_at):
6089 * fontset.c (fontset_id_valid_p, reorder_font_vector
6090 (fontset_find_font, Fset_fontset_font)
6091 (face_suitable_for_char_p) [0]:
6092 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6093 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6094 (m17n_flt_initialized, ftfont_shape_by_flt):
6095 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6096 * nsfont.m (nsfont_draw):
6097 * w32font.c (w32font_draw):
6098 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6099 Use bool for booleans.
6100 * font.h: Adjust to above API changes.
6101 (struct font, struct font_driver, struct font_driver_list):
6102 Use bool for booleans.
6103 (struct font): Remove useless member encoding_type.
6105 * fontset.c, xftfont.c: Omit unnecessary static decls.
6107 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6109 * alloc.c (mark_object): Revert window marking code
6110 since it's unsafe for the Fset_window_configuration.
6112 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6114 Fix race conditions with signal handlers and errno (Bug#12327).
6115 Be more systematic about preserving errno whenever a signal
6116 handler returns, even if it's not in the main thread. Do this by
6117 renaming signal handlers to distinguish between signal delivery
6118 and signal handling. All uses changed.
6119 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6120 * data.c (deliver_arith_signal): Rename from arith_error.
6121 * dispnew.c (deliver_window_change_signal): Rename from
6122 window_change_signal.
6123 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6124 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6125 * keyboard.c (deliver_input_available_signal): Rename from
6126 input_available_signal.
6127 (deliver_user_signal): Rename from handle_user_signal.
6128 (deliver_interrupt_signal): Rename from interrupt_signal.
6129 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6130 (deliver_child_signal): Rename from sigchld_handler.
6131 * atimer.c (handle_alarm_signal):
6132 * data.c (handle_arith_signal):
6133 * dispnew.c (handle_window_change_signal):
6134 * emacs.c (handle_fatal_signal, handle_danger_signal):
6135 * keyboard.c (handle_input_available_signal):
6136 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6137 * process.c (handle_pipe_signal, handle_child_signal):
6138 New functions, with the actual signal-handling code taken from the
6139 original respective signal handlers, sans the sporadic attempts to
6140 preserve errno, since that's now done by handle_on_main_thread.
6141 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6142 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6143 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6145 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6146 Move initialization of main_thread to sysdep.c's init_signals.
6147 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6148 our usage, and simplifies the mainline code.
6149 (record_child_status_change): New static function, as a helper
6150 for handle_child_signal, and with most of the old child handler's
6152 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6153 (handle_child_signal): Use the above.
6154 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6155 Moved here from emacs.c.
6156 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6157 code moved here from emacs.c's main function.
6158 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6159 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6160 This lets callers save and restore errno properly.
6162 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6164 Remove redundant or unused things here and there.
6165 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6166 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6167 * editfns.c (Fcompare_buffer_substrings): Likewise.
6168 * frame.h (struct terminal, struct font_driver_list):
6169 Remove redundant declarations.
6170 * window.h (Qleft, Qright): Likewise.
6172 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6174 Do not mark objects from deleted buffers, windows and frames.
6175 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6176 (mark_object): Likewise for windows and frames.
6178 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6180 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6181 buffer_defaults and buffer_local_symbols as valid objects.
6182 Return special value to denote them.
6184 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6186 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6187 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6188 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6189 (file_name_absolute_p, Fsubstitute_in_file_name):
6190 (check_executable, check_writable, Ffile_accessible_directory_p)
6191 (Fset_file_selinux_context, Fdefault_file_modes)
6192 (Finsert_file_contents, choose_write_coding_system)
6193 (Fwrite_region, build_annotations, a_write, e_write)
6195 * filelock.c (boot_time_initialized, get_boot_time)
6196 (get_boot_time_1, lock_file_1, within_one_second):
6197 * floatfns.c (in_float):
6198 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6199 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6200 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6201 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6202 * window.c (compare_window_configurations):
6203 Use bool for booleans.
6204 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6205 (Fdefault_file_modes): Now mode_t, not int, for modes.
6206 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6207 (internal_delete_file): Now returns void, not a (boolean) int,
6208 since nobody was looking at the return value.
6209 * lisp.h, window.h: Adjust to above API changes.
6211 * xdisp.c (set_message): Simplify and reindent last change.
6213 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6215 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6217 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6219 * eval.c (call_debugger): Make the function non-static so that we
6220 can call it from set_message.
6222 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6223 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6225 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6227 Give more-useful info on a fatal error (Bug#12328).
6228 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6229 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6230 of doing the work ourselves.
6231 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6232 do most of the work.
6233 (fatal_error_backtrace): New function, taken from the guts
6234 of the old fatal_error_signal, but with a new option to output
6236 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6237 info about the signal than just its number.
6238 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6239 * sysdep.c: Include <execinfo.h>
6240 (emacs_backtrace): New function, taken partly from the previous
6241 code of the 'die' function.
6242 (emacs_abort): Call fatal_error_backtrace rather than abort.
6244 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6246 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6247 eager (load-time) macro-expansion.
6248 * lisp.mk (lisp): Add macroexp.
6250 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6252 Simplify redefinition of 'abort' (Bug#12316).
6253 Do not try to redefine the 'abort' function. Instead, redo
6254 the code so that it calls 'emacs_abort' rather than 'abort'.
6255 This removes the need for the NO_ABORT configure-time macro
6256 and makes it easier to change the abort code to do a backtrace.
6257 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6258 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6259 Remove; sysdep.c's emacs_abort now takes its place.
6260 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6261 'abort' changed to use 'emacs_abort'.
6262 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6263 (abort) [!defined abort]: Rename to ...
6264 (emacs_abort): ... new name.
6265 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6266 the place of the old 'abort' in emacs.c.
6267 * w32.c, w32fns.c (abort): Do not #undef.
6268 * w32.c (emacs_abort): Rename from w32_abort.
6270 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6272 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6273 offsets[j].dv, since the y axis of the screen coordinates points
6274 down, while the y axis of the font definition coordinates points
6275 up. This fixes display of Arabic diacritics such as KASRA and
6276 KASRATAN. (Bug#11860)
6278 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6280 Be more systematic about _setjmp vs setjmp.
6281 * alloc.c (test_setjmp, mark_stack):
6282 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
6283 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
6284 (png_load, my_error_exit, jpeg_load):
6285 * process.c (send_process_trap, send_process):
6286 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6287 The underscored versions are up to 30x faster on some hosts.
6288 Formerly, the code used setjmp+longjmp sometimes and
6289 _setjmp+_longjmp at other times, with no particular reason to
6290 prefer setjmp+longjmp.
6292 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
6294 Fix minor problem found by static checking.
6295 * buffer.c (Fdelete_all_overlays): Return nil.
6297 2012-09-03 Martin Rudalics <rudalics@gmx.at>
6299 * buffer.c (Fdelete_all_overlays): New function.
6301 2012-09-03 Chong Yidong <cyd@gnu.org>
6303 * gtkutil.c: Add extern decl for Qxft.
6305 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
6307 * emacs.c, eval.c: Use bool for boolean.
6308 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
6309 (malloc_using_checking) [DOUG_LEA_MALLOC]:
6310 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
6311 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
6312 (main, decode_env_path, Fdaemon_initialized):
6313 * eval.c (call_debugger, Finteractive_p, interactive_p):
6314 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
6315 (maybe_call_debugger, Fbacktrace):
6316 * process.c (read_process_output, exec_sentinel):
6317 Use bool for booleans.
6318 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
6319 All callers changed.
6320 * eval.c (interactive_p): Omit always-true boolean argument
6321 EXCLUDE_SUBRS_P. All callers changed.
6322 * dispextern.h, lisp.h: Reflect above API changes.
6323 * firstfile.c (dummy): Use the address of 'main', whose signature
6324 won't change, instead of the address of 'initialize', whose
6325 signature just changed from int to bool.
6326 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
6327 * msdos.c (fatal_error_in_progress): ... from here.
6328 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6330 (redisplay_internal, unwind_redisplay): Simply clear
6331 REDISPLAYING_P when unwinding, instead of saving its previous,
6332 always-false value and then restoring it.
6334 Clean up some extern decls.
6335 Mostly, this hoists extern decls out of .c files and into .h files.
6336 That way, we're more likely to catch errors if the interfaces change.
6337 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6338 declare xg_mark_data.
6339 * dispextern.h (x_frame_parm_handlers):
6341 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
6342 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
6343 (Qultra_bold, Qoblique, Qitalic):
6344 Move extern decl here from .c file.
6345 * alloc.c (xg_mark_data) [USE_GTK]:
6347 * eval.c (Qlexical_binding):
6348 * fns.c (time) [!HAVE_UNISTD_H]:
6349 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
6350 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):
6351 * image.c (Vlibrary_cache, QCloaded_from) [HAVE_NTGUI]:
6352 * lread.c (Qinternal_interpreter_environment):
6353 * minibuf.c (Qbuffer):
6354 * process.c (QCfamily, QCfilter):
6355 * widget.c (free_frame_faces):
6356 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
6357 * xfont.c (x_clear_errors):
6358 * xterm.c (x_frame_parm_handlers):
6359 Remove now-redundant extern decls.
6360 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
6361 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
6363 * xfaces.c: Remove unnecessary static decls.
6364 * xterm.c (updating_frame): Remove decl of nonexistent object.
6366 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
6367 when building globals.h, as the objects that are not built on
6368 this host are not needed to compile C files on this host.
6370 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>

6424 offset adjustment values separately for each cluster. (Bug#11860)
6426 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6427 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6428 about implicit conversions from integer to pointer.

6486 window system declarations.
6488 * frame.h: Move common functions here: set_frame_menubar,
6489 x_set_window_size, x_sync, x_get_focus_frame,
6490 x_set_mouse_position, x_set_mouse_pixel_position,
6491 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6548 for GCC 4.7.1 x86-64.
6550 2012-08-30 Glenn Morris <rgm@gnu.org>
6552 * lread.c (init_lread): For out-of-tree builds, only add the
6553 source directory's site-lisp dir to the load-path if it exists,
6554 consistent with in-tree builds. (Bug#12302)
6556 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

6577 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
6578 Add window_closed and button_values. Add void as return value for

6787 are all boolean, so make them single-bit bitfields.
6789 * lisp.h (ASET): Remove attempt to detect side effects.
6790 It was meant to be temporary and it often doesn't work,
6791 because when IDX has side effects the behavior of IDX==IDX
6792 is undefined. See Stefan Monnier in
6793 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6795 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)

6803 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6804 as that's faster and simpler than static storage. Don't bother
6805 with the g_main_context_query overhead if g_main_context_pending
6806 says no events are pending.
6807 (gfds, gfds_size): Remove these static vars.
6808 (xgselect_initialize): Remove; no longer needed.
6809 All uses and decls removed.

6823 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6825 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6827 On assertion failure, print backtrace if available.
6828 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6829 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6830 * Makefile.in (LIB_EXECINFO): New macro.
6833 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6834 * bytecode.c (exec_byte_code):
6835 * callint.c (check_mark, Fcall_interactively):
6836 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6837 (getenv_internal, sync_process_alive, call_process_exited):
6838 * lisp.h (USE_SAFE_ALLOCA):
6839 Use bool for booleans, instead of int.
6840 * lisp.h, process.h: Adjust prototypes to match above changes.
6841 * callint.c (Fcall_interactively): Don't assume the mark's
6842 offset fits in 'int'.
6844 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6846 * buffer.c, buffer.h: Use bool for boolean.
6847 * buffer.c (reset_buffer_local_variables)
6848 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6849 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6850 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6851 (overlay_touches_p, overlay_strings, Foverlay_put)
6852 (report_overlay_modification, call_overlay_mod_hooks):
6853 (mmap_enlarge, mmap_set_vars):
6854 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6855 Use bool for booleans, instead of int.
6856 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6857 since the 1-or-0 return value is always ignored anyway.
6858 (mmap_initialized_p):
6859 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6860 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6862 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6864 * bidi.c: Use bool for boolean.
6865 This is a bit more readable, and makes the text segment of bidi.o
6866 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6867 Presumably it's faster too.
6868 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6870 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6871 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6872 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6873 (bidi_explicit_dir_char, bidi_level_of_next_char)
6874 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6875 Use bool for booleans, instead of int.
6876 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6877 (bidi_unshelve_cache): Adjust decls to match code.
6879 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6881 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6884 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6886 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6887 * atimer.h: Include <stdbool.h>.
6889 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6891 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6892 compile time tests instead of run time tests on systems that do
6894 (FRAME_MAC_P): Remove leftover from deleted code.
6895 * frame.c (syms_of_frame): Remove leftover from deleted code.
6897 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6899 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6901 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6903 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6904 Otherwise, the compiler complains about (A?B:C) where B is void
6905 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6906 (fontset_add): Return void, for FONTSET_ADD.
6908 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6910 * alloc.c: Use bool for booleans.
6911 (gc_in_progress, abort_on_gc)
6912 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6913 (dont_register_blocks) [GC_MALLOC_CHECK]:
6914 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6915 (check_string_bytes, make_specified_string, memory_full)
6916 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6917 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6918 (mark_stack, valid_pointer_p, make_pure_string)
6919 (Fgarbage_collect, survives_gc_p, gc_sweep):
6920 Use bool for booleans, instead of int.
6921 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6922 Remove unused local.
6923 * alloc.c (PURE_POINTER_P):
6924 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6925 * editfns.c (Fformat):
6926 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6928 * fns.c (sweep_weak_table):
6929 * lisp.h (suppress_checking, push_message, survives_gc_p)
6930 (make_pure_string, gc_in_progress, abort_on_gc):
6931 * lread.c (readchar, read1):
6932 * print.c (Fprin1_to_string):
6933 * xdisp.c (push_message):
6934 Use bool for booleans affected directly or indirectly by
6937 Make recently-introduced setters macros.
6938 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6939 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6940 (set_fontset_default, set_fontset_fallback): Rename from their
6941 upper-case counterparts, and make them functions rather than macros.
6942 This is more consistent with the other recently-introduced setters.
6943 These don't need to be inline, since they're local.
6945 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6947 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6948 the loop (Bug#12247).
6950 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6952 * lisp.h (vcopy): Use memcpy rather than our own loop.
6953 This fixes a performance regression introduced by the recent
6954 addition of vcopy. This means 'vcopy' will need to be modified
6955 for a copying collector, but that's OK. Also, tighten the
6956 checking in the assertion.
6958 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6960 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6961 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6962 non-base glyph for the width of the base character, according to
6963 what x_draw_composite_glyph_string_foreground expects.
6964 Generate WADJUST value according to composition_gstring_width's
6965 expectations, to produce correct width of the composed character.
6966 Reverse the sign of the DU offset produced by ScriptPlace.
6968 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6970 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6972 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6974 Avoid direct writes to contents member of struct Lisp_Vector.
6975 * lisp.h (vcopy): New function to copy data into vector.
6976 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6977 * fns.c (Ffillarray): Use ASET.
6978 * keyboard.c (timer_check_2): Use AREF and ASET.
6979 (append_tool_bar_item, Frecent_keys): Use vcopy.
6980 * lread.c (read_vector): Use ASET.
6981 * msdos.c (Frecent_doskeys): Use vcopy.
6982 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6983 (Finternal_merge_in_global_face): Use ASET and vcopy.
6984 * xfont.c (xfont_list_pattern): Likewise.

6989 the position of its buffer's point.
6990 (Fset_window_point): For the selected window always go in its
6991 buffer to the specified position.
6993 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6995 Setter macros for fontsets.
6996 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6997 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6998 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7001 2012-08-20 Glenn Morris <rgm@gnu.org>
7003 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7004 Don't assume that `ln -f' works.
7006 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7008 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
7009 and later about non-assignments with no effect. See discussion at
7010 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
7013 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7015 Inline setter functions for Lisp_Objects slots of struct specbinding.
7016 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
7019 2012-08-20 Martin Rudalics <rudalics@gmx.at>
7021 * window.c (select_window): Always make selected window's buffer
7024 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7026 Use AREF and ASET for docstrings of category tables.
7027 * category.h (CATEGORY_DOCSTRING): Use AREF.
7028 (SET_CATEGORY_DOCSTRING): Use ASET.
7029 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
7031 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7033 Inline setter functions for hash table members.
7034 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
7035 (set_hash_hash, set_hash_index): Rename with _slot suffix.
7036 (set_hash_key_and_value, set_hash_index, set_hash_next)
7037 (set_hash_hash): New functions.
7038 * charset.c, fns.c: Adjust users.
7040 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7042 Inline getter and setter functions for per-buffer values.
7043 * buffer.h (per_buffer_default, set_per_buffer_default)
7044 (per_buffer_value, set_per_buffer_value): New functions.
7045 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
7046 * buffer.c, data.c: Adjust users.
7048 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
7050 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
7052 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7054 Rely on <config.h> + <unistd.h> to declare 'environ',
7055 as gnulib does this if the system doesn't.
7056 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7057 Remove declaration. MS-Windows declares it on stdlib.h which is
7058 included by conf_post.h.
7059 * emacs.c (environ) [DOUG_LEA_MALLOC]:
7060 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
7061 * vm-limit.c: Include <unistd.h>, for 'environ'.
7063 * unexaix.c, unexcoff.c: Include "mem-limits.h".
7064 (start_of_data): Remove decl; mem-limits.h provides it.
7066 * xdisp.c (handle_invisible_prop): Make it a bit faster
7067 and avoid a gcc -Wmaybe-uninitialized diagnostic.
7069 2012-08-19 Chong Yidong <cyd@gnu.org>
7071 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
7074 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
7076 * .gdbinit: Use call instead of set when calling a function in the
7079 * data.c (set_internal): Don't use set_blv_found.
7080 (Fkill_local_variable): Likewise.
7082 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
7084 * nsfont.m (ns_ascii_average_width): Ensure the string
7085 ascii_printable is initialized with a null-terminated character
7086 array. Otherwise, it can contain undesired extra characters.
7088 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7090 port new setting code to Sun C 5.8 2005/10/13
7091 * chartab.c, lisp.h (char_table_set, char_table_set_range):
7092 Return void, not Lisp_Object. Otherwise, the compiler
7093 complains about (A?B:C) where B is void and C is Lisp_Object
7094 when compiling CHAR_TABLE_SET, due to the recent change to
7095 the API of sub_char_table_set_contents.
7097 2012-08-18 Chong Yidong <cyd@gnu.org>
7099 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
7100 for the string case (Bug#3874).

7927 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
7928 * w32.c (init_environment): Change the default values of many
7929 environment variables in dflt_envvars[] to NULL, to avoid pushing
7930 them into environment when they were not already defined.
7931 Remove the code that deletes site-lisp subdirectories from the default
7932 value of EMACSLOADPATH, as it is no longer needed.
7933 (check_windows_init_file): Now external, not static.
7934 Use Vload_path as is, without adding anything, as this function is now
7935 called when Vload_path is already set up.
7937 * w32.h (check_windows_init_file): Add prototype.
7939 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

7946 installation tree, as appropriate.
7948 * callproc.c (init_callproc_1): Call decode_env_path instead of
7949 doing its equivalent by hand.

7951 the code that sets Vexec_path run on MS-Windows.
7953 * lread.c (init_lread): Add comments to #ifdef's.
7955 * msdos.c (dos_set_window_size, IT_update_begin)

7967 Remove unnecessary casts involving pointers.
7968 These casts are no longer needed now that we assume C89 or later,

7982 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
7983 Remove unnecessary pointer casts.
7984 * alloc.c (record_xmalloc): New function.
7985 * lisp.h (record_xmalloc): New decl.
7986 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7987 more like a function. This is because the pointer cast is not
7988 needed. All uses changed.
7989 * print.c (print_string, print_error_message): Avoid length recalc.
7991 Improve fix for macroexp crash with debugging (Bug#12118).
7992 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7993 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7994 not supposed to be invoked from the garbage collector.
7995 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
7996 (gc_aset): New function, which is like ASET but can be
7997 used in the garbage collector.
7998 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

8013 headers (most versions of MinGW w32api don't).
8014 (get_security_info, create_symbolic_link)
8015 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
8017 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks

8021 (sys_rename): Diagnose renaming of a symlink when the user doesn't
8022 have the required privileges.
8023 (get_file_security_desc_by_name): Rename from
8024 get_file_security_desc.

8026 with addition of handling of symlinks and support for 'lstat'.
8027 If possible, get file's attributes and security information by
8028 handle, not by name. Produce S_IFLNK bit for symlinks, when
8029 called from 'lstat'.
8030 (stat, lstat): New functions, call 'stat_worker'.
8031 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8032 symlinks when the underlying filesystem supports them.
8034 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
8036 Fix macroexp crash on Windows with debugging (Bug#12118).
8037 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8038 checking subscripts; problem introduced with the recent
8039 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8040 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8041 since it's used in non-static inline functions now.
8043 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
8044 Don't assume buffer size fits in 'int'. Remove unused local.

8064 * composite.c (COMPOSITE_INLINE):
8065 * dispnew.c (DISPEXTERN_INLINE):
8066 * sysdep.c (SYSTIME_INLINE):
8067 Define to EXTERN_INLINE, so that the corresponding functions
8068 are compiled into code.
8069 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
8070 (INLINE_HEADER_END): New macros.
8071 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

8091 hard-coding the path separator.
8093 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
8095 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
8096 This how ASET and AREF are supposed to work, and makes
8097 it easier to think about future improvements. See
8098 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
8099 * charset.h (set_charset_attr): New function.

8587 Fix export of symbols to GDB (Bug#12036).
8588 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
8589 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
8590 emacs.c, as this is a more-suitable home. Had this been done earlier
8591 the fix for 12036 would have avoided some of the problems noted in
8592 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8593 would have been more obvious.
8594 * emacs.c: Do not include <verify.h>; no longer needed.
8595 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
8596 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
8597 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8598 Remove; now done in lisp.h.
8599 * lisp.h (PUBLISH_TO_GDB): New macro.
8600 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
8601 (DATA_SEG_BITS): Use it.
8602 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
8603 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8604 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8605 not be usable in #if. This simplifies things.
8607 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8609 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
8611 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
8613 Simplify export of symbols to GDB (Bug#12036).
8614 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8615 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8616 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8617 Adjust to changes in lisp.h and emacs.c, by using
8618 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8619 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8620 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8621 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8622 instead of gdb_valbits.
8623 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8624 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8625 instead of gdb_array_mark_flag.
8626 (xboolvector): Get size from $->size, not $->header.size.
8627 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8628 (xreload, hook-run, hookpost-run): Remove.
8629 * emacs.c: Include <verify.h>.
8630 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8631 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8633 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8634 (gdb_USE_LSB_TAG): New enum constants.
8635 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8636 Also define these as enum constants, so they're visible to GDB.
8637 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8638 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8639 as constants, so they're visible to GDB.
8640 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
8641 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
8642 Now enum constants, not macros, so they're visible to GDB.
8643 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8644 more convenient now. All uses changed.
8645 (VALMASK) [USE_LSB_TAG]: Also define in this case.
8646 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
8648 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
8650 Explicitly free restriction data that are not needed anymore.
8651 * editfns.c (save_restriction_restore): Free restriction data.
8653 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
8655 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
8656 add argument, tune behavior, and adjust all callers.
8658 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8660 Use typedef for EMACS_INT, EMACS_UINT.
8661 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8662 than macros. This simplifies debugging in the usual case, since
8663 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8664 and it allows expressions involving EMACS_INT casts.
8665 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8667 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
8669 * nsterm.m (ns_read_socket): Return early if there is a modal

8675 that FOCUS-FRAME can be omitted.
8677 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
8679 Adjust buffer text indirection counters at the end of Fkill_buffer.
8680 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8681 buffer is definitely dead. This should really fix an issue reported
8682 by Christoph Scholtes again. (Bug#12007).
8683 (init_buffer_once): Initialize indirection counters of
8684 buffer_defaults and buffer_local_symbols (for sanity and safety).
8686 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8688 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8689 and continuation glyphs on tooltip frames, leave them at zero.
8690 Avoids continued lines in tooltips. (Bug#11832)
8692 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
8694 Simplify copy_overlay.
8695 * buffer.c (copy_overlay): Simplify. Use build_marker.

8701 or invalid. (Bug#12025)
8703 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
8704 it signals an error when a tooltip frame is being created.
8706 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8708 Cleanup miscellaneous objects allocation and initialization.
8709 * alloc.c (allocate_misc): Change to static. Add argument to
8710 specify the subtype. Adjust comment and users.
8711 (build_overlay): New function.
8712 * buffer.c (copy_overlays, Fmake_overlay): Use it.
8713 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.

8715 (build_overlay): Add prototype.
8717 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8719 Swap buffer text indirection counters in Fbuffer_swap_text.
8720 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8721 This avoids crash reported by Christoph Scholtes at
8722 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8724 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8726 * nsmenu.m (Popdown_data): New struct.
8727 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
8729 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.

8731 and autorelease them. Also autorelease img and matrix (Bug#12005).
8732 (dealloc): Remove (Bug#12005).

8745 (live_buffer, set_marker_internal): New function.
8746 (Fset_marker, set_marker_restricted): Use set_marker_internal.

8749 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8751 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8752 as it's limited by the amount of memory, not by INT_MAX.
8754 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8756 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8757 in special-event-map. See the discussion at

8892 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
8894 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug

8907 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8909 * eval.c (Fdefvar): Don't check constants since we only set the var if
8910 it's not yet defined anyway (bug#11904).
8912 * lisp.h (last_undo_boundary): Declare new var.
8913 * keyboard.c (command_loop_1): Set it.
8914 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
8915 were auto-added by the command loop (bug#11774).
8917 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>

9485 The functional style also makes code easier to read and maintain.
9486 * systime.h: Include <sys/time.h> on all hosts, not just if
9487 WINDOWSNT, since 'struct timeval' is needed in general.
9488 (EMACS_TIME): Now a typedef, not a macro.
9489 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
9491 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
9492 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
9493 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
9494 (EMACS_TIME_LE): Now functions, not macros.
9495 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
9496 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
9497 which are not functions. All uses rewritten to use:
9498 (make_emacs_time): New function.
9499 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
9500 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
9501 not functions. All uses rewritten to use the following, respectively:
9502 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
9503 (add_emacs_time, sub_emacs_time): New functions.
9504 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
9505 * fileio.c (Fcopy_file):
9506 * xterm.c (XTflash): Get the current time closer to when it's used.
9507 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

9514 * frame.c (Fmake_terminal_frame):
9515 * gtkutil.c (get_utf8_string):
9517 * nsmenu.m (ns_update_menubar):
9518 * regex.c (regerror):
9519 Prefer memcpy to strncpy and strncat when either will do.

9521 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
9522 (menu_separator_name_p):
9523 * nsmenu.m (ns_update_menubar):
9524 Prefer memcmp to strncmp when either will do.
9525 * nsterm.m: Include <ftoastr.h>.
9527 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9528 Prefer snprintf to strncpy.
9529 * nsterm.m (ns_term_init):
9530 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9531 * nsterm.m (ns_term_init):
9532 Avoid the need for strncpy, by using build_string or
9533 make_unibyte_string directly. Use dtoastr, not snprintf.
9534 * process.c (Fmake_network_process): Diagnose service names that
9535 are too long, rather than silently truncating them or creating
9536 non-null-terminated names.
9537 (Fnetwork_interface_info): Likewise, for interface names.
9538 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9539 Prefer sprintf to strncat.
9540 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
9541 Prefer vsnprintf to vsprintf + strncpy.
9543 2012-07-10 Glenn Morris <rgm@gnu.org>
9545 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
9546 Clarify fallback case.
9548 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9550 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
9551 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
9552 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
9553 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9554 where argument type is known to be a Lisp_Cons.

9566 Optimize pure C strings initialization.
9567 * lisp.h (make_pure_string): Fix prototype.
9568 (build_pure_c_string): New function, defined as static inline. This
9569 provides a better opportunity to optimize away calls to strlen when
9570 the function is called with compile-time constant argument.
9571 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9572 argument, adjust users accordingly. Use build_pure_c_string where
9574 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9575 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9576 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9578 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9580 Avoid calls to strlen in miscellaneous functions.
9581 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
9582 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
9583 * lread.c (openp): Likewise.
9585 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9587 Avoid calls to strlen in path processing functions.
9588 * fileio.c (file_name_as_directory): Add comment. Change to add
9589 srclen argument and return the length of result. Adjust users
9591 (directory_file_name): Fix comment. Change to add srclen argument,
9592 swap 1st and 2nd arguments to obey the common convention.
9593 Adjust users accordingly.
9594 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
9596 2012-07-10 Glenn Morris <rgm@gnu.org>
9598 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
9599 Move PENDING_OUTPUT_COUNT definition to configure.
9601 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
9602 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
9603 * s/gnu.h (DATA_START): Move definitions to configure.
9605 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9606 We include usg5-4-common.h, which defines them both.
9608 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9609 O_RDONLY already includes it).
9611 Stop ns builds setting the EMACSLOADPATH environment variable.
9612 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9613 Now it does not set EMACSLOADPATH, just returns the load-path string.
9614 * nsterm.h: Update accordingly.
9615 * lread.c [HAVE_NS]: Include nsterm.h.
9616 (init_lread) [HAVE_NS]: Use ns_load_path.
9617 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
9619 2012-07-09 Glenn Morris <rgm@gnu.org>
9621 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9622 since the included bsd-common.h does so.
9624 Stop ns builds setting the EMACSPATH environment variable.
9625 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9626 (ns_init_paths): Do not set EMACSPATH.
9627 * nsterm.h (ns_exec_path): Add it.
9628 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9631 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9633 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9635 * process.c (wait_reading_process_output): 'waitchannels' was unset
9636 when read_kbd || !NILP (wait_for_cell); fix this.
9638 Add GCC-style 'const' attribute to functions that can use it.
9639 * character.h (char_resolve_modifier_mask):
9640 * keyboard.h (make_ctrl_char):
9641 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
9642 (init_character_once, next_almost_prime, init_fns, init_image)
9643 (flush_pending_output, init_sound):

9648 Declare the dummy function with ATTRIBUTE_CONST.
9649 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
9650 Add decls with ATTRIBUTE_CONST.
9652 Minor improvements to make_formatted_string.
9653 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9654 where int is good enough, as vsprintf returns an int.
9655 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9657 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9659 Use make_formatted_string to avoid double length calculation.
9660 * lisp.h (make_formatted_string): New prototype.
9661 * alloc.c (make_formatted_string): New function.
9662 * buffer.c (Fgenerate_new_buffer_name): Use it.
9663 * dbusbind.c (syms_of_dbusbind): Likewise.

9665 * filelock.c (get_boot_time): Likewise.
9666 * frame.c (make_terminal_frame, set_term_frame_name)
9667 (x_report_frame_params): Likewise.
9668 * image.c (gs_load): Likewise.
9669 * minibuf.c (get_minibuffer): Likewise.

9684 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9686 Move marker debugging code under MARKER_DEBUG.
9687 * marker.c (MARKER_DEBUG): Move marker debugging code under
9688 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9689 for bootstrap with --enable-checking (~3x slowdown reported
9690 by Juanma Barranquero <lekktu@gmail.com>).
9691 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9693 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9695 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9696 See <http://bugs.gnu.org/11825#29>.
9698 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9700 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9701 has no font, use the frame's font. (Bug#11813)
9702 (display_line): Add commentary about displaying truncation glyphs
9704 (produce_special_glyphs): Move here from term.c.
9706 * term.c (produce_special_glyphs): Move to xdisp.c.
9708 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9711 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9713 * xdisp.c (display_line): Avoid warning about implicit declaration
9716 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9718 * lisp.h: Remove empty conditional.
9720 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9722 * lread.c (load_path_check): Now static.
9724 Fix some minor --with-ns problems found by static checking.
9725 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9726 (x_set_font) [!HAVE_X_WINDOWS]:
9727 * image.c (xpm_load_image) [HAVE_NS]:
9728 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9729 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9730 Remove unused local.
9731 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9732 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9733 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9734 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9735 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9736 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9737 Fix pointer signedness problem.
9738 * xfaces.c (FRAME_X_FONT_TABLE):
9739 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9741 2012-07-07 Glenn Morris <rgm@gnu.org>
9743 * lread.c (load_path_check): New function, split from init_lread.
9744 (init_lread): Reorganize. Motivation:
9745 If EMACSLOADPATH is set, check/warn about that rather than the
9746 defaults, which we are not going to use. Hence we can remove
9747 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9748 Don't warn if site-lisp directories are missing.
9749 If not installed, start from a blank load-path, since
9750 PATH_LOADSEARCH refers to the eventual installation directories.
9752 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9754 Support truncation and continuation glyphs on GUI frames, when
9755 fringes are disabled. (Bug#11832)
9756 * xdisp.c (init_iterator): Get dimensions of truncation and
9757 continuation glyphs even if on GUI frames.
9758 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9759 or both, are absent.
9760 (start_display, move_it_in_display_line_to): Handle the case of a
9761 GUI frame without a fringe to display continuation or truncation
9763 (insert_left_trunc_glyphs): Support GUI frames: make sure
9764 truncation glyphs overwrite enough glyphs from the current line to
9765 have sufficient space in pixels.
9766 (display_line): Support truncation and continuation glyphs on GUI
9767 frames. If some spare pixels are left on the line after inserting
9768 the truncation glyphs, fill that space with a stretch glyph of a
9769 suitably computed width.
9771 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9772 produce_glyphs, to support GUI sessions.
9774 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9776 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9778 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9780 Do not require float-time's arg to fit in time_t (Bug#11825).
9781 This works better on hosts where time_t is unsigned, and where
9782 float-time is applied to the (negative) difference between two times.
9783 * editfns.c (decode_time_components): Last arg is now double *,
9784 not int *, and means to store all the result as a double, without
9785 worrying about whether the seconds part fits in time_t.
9786 All callers changed.
9787 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9788 All callers changed.
9789 (Ffloat_time): Do not fail merely because the specified time falls
9790 outside of time_t range.
9792 2012-07-07 Glenn Morris <rgm@gnu.org>
9794 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
9795 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
9796 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
9798 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
9800 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
9801 Update dependencies.
9803 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
9805 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9807 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
9808 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
9809 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9810 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9811 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
9812 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
9814 * xfont.c (compare_font_names): Redo to omit the need for casts.
9816 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9818 * xfns.c (Fx_change_window_property): Doc fix.
9819 * w32fns.c (Fx_change_window_property): Doc fix.
9821 * w32fns.c (Fx_window_property): Accept the same arguments as the
9822 X Windows version. Doc fix.
9823 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9825 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9826 Eli Zaretskii <eliz@gnu.org>
9828 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9829 Windows-specific code from nt/config.nt moved here.
9830 Obsolete settings removed.
9832 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9834 * process.c: Avoid unnecessary calls to gettime.
9835 (wait_reading_process_output): Don't get the time of day
9836 when gobbling data immediately and not waiting, as there's no need
9837 for it in that case. This removes a FIXME.
9839 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9841 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9842 is defined (Bug#11768).
9844 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9846 Fix marker debugging code.
9847 * marker.c (byte_char_debug_check): Do not perform the check
9848 if buffer is not multibyte.
9849 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9850 Call byte_char_debug_check with correct arguments.
9852 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9854 Compile marker debugging code only if ENABLE_CHECKING is defined.
9855 * marker.c (byte_char_debug_check, count_markers):
9856 Use only if ENABLE_CHECKING is defined.
9857 (byte_debug_flag): Remove.
9858 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9859 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9861 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9863 Avoid code repetition in marker-related functions.
9864 * marker.c (attach_marker): New function.
9865 (Fset_marker, set_marker_restricted, set_marker_both)
9866 (set_marker_restricted_both): Use it.
9867 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9868 Consistently rename charno to charpos.
9869 (marker_position): Add eassert.
9870 (marker_byte_position): Convert to eassert.
9872 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9874 Simplify list operations in unchain_overlay and unchain_marker.
9875 * buffer.c (unchain_overlay): Simplify. Add comment.

9888 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
9889 * window.c (save_window_save): Likewise.
9891 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9893 Do not use Fdelete_overlay in delete_all_overlays
9894 to avoid redundant calls to unchain_overlay.
9895 * buffer.c (drop_overlay): New function.
9896 (delete_all_overlays, Fdelete_overlay): Use it.
9897 * minibuf.c (get_minibuffer): Fix comment.
9899 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9901 Port to OpenBSD 5.1 amd64.
9902 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9903 This is needed for OpenBSD, and should be harmless on all BSD systems.
9904 Also, include <sys/sysctl.h>, as it should be available on all
9905 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9906 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9907 use p_pid member, not kp_proc.pid.
9909 2012-07-06 Glenn Morris <rgm@gnu.org>
9911 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9913 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9915 More xmalloc and related cleanup.
9916 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
9917 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

9924 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9926 Omit needless casts involving void * pointers and allocation.
9927 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9928 as the former is more robust if P's type is changed.
9929 Prefer xzalloc to xmalloc + memset 0.
9930 Simplify malloc-or-realloc to realloc.
9931 Don't worry about xmalloc returning a null pointer.
9932 Prefer xstrdup to xmalloc + strcpy.
9933 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9935 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9936 alloca of a constant.
9938 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9940 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9941 hscroll is larger than the line width. Fixes long and futile
9942 looping inside extend_face_to_end_of_line (on a TTY) producing
9943 glyphs that are not needed and thrown away.
9945 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

9965 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
9966 (is_box_type): New function (Bug#11768).
9967 (xg_tool_item_stale_p): Call is_box_type.
9968 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
9969 with default display (Bug#11768).

10041 * fileio.c (time_error_value): Check the right error number.
10042 Problem reported by Troels Nielsen in
10043 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10045 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10047 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10048 This should be fixed in a better way; see Eli Zaretskii in
10049 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10050 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10052 * fileio.c (time_error_value): Rename from special_mtime.
10053 The old name's problems were noted by Eli Zaretskii in
10054 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10056 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10057 This variable's comment says Emacs needs at least one GDB-visible
10058 symbol of type enum pvec_type, to work around GDB problems.
10059 The symbol's value doesn't matter.
10061 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10062 that causes compilation to fail on pre-C99 compilers.
10064 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10066 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

10071 * buffer.c (init_buffer_once): Fix initialization of
10072 headers for buffer_defaults and buffer_local_symbols.
10073 Reported by Juanma Barranquero <lekktu@gmail.com>.
10075 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
10077 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
10078 * lisp.h (enum pvec_type): Use fewer bits.
10079 (PSEUDOVECTOR_SIZE_BITS): New constant.
10080 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
10081 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
10082 change in pvec_type.
10083 (PSEUDOVECTOR_TYPEP): New macro.
10084 (TYPED_PSEUDOVECTORP): Use it.
10085 * fns.c (internal_equal): Adapt code to extract pvectype.
10086 * emacs.c (gdb_pvec_type): Update type.
10087 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
10088 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
10089 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
10090 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10091 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10092 abusing vector->header.next.nbytes.
10093 (live_vector_p): Use PVEC_TYPE.
10094 (mark_object): Adapt code to extract pvectype. Use switch.
10096 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10098 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10099 Tighten new eassert a bit.
10101 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10103 Fix compilation with --enable-gcc-warnings and -O1
10104 optimization level.
10105 * doprnt.c (doprnt): Change type of tem to int, initialize
10106 to avoid compiler warning. Add eassert.
10107 * search.c (simple_search): Initialize match_byte to avoid
10108 compiler warning. Add eassert.
10110 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10112 Avoid weird behavior with large horizontal scrolls.
10113 Without this change, for example, large hscroll values would
10114 mess up Emacs's display on Fedora 15 x86, presumably due to
10115 overflows in int calculations in the display code.
10116 Also, if buffers had long lines, Emacs would freeze.
10117 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10118 (set_window_hscroll): New function, containing the old guts of
10119 Fset_window_hscroll. Return the clipped value.
10120 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10121 This avoids the need to check against PTRDIFF_MAX.
10123 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10125 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10127 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10129 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10131 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10132 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10133 since GCC 4.4.6 issues a bogus warning for them.
10135 Fix bugs in file timestamp newness comparisons.
10136 * fileio.c (Ffile_newer_than_file_p):
10137 * lread.c (Fload): Use full timestamp resolution of files,
10138 not just the 1-second resolution, so that files that are only
10139 slightly newer still count as newer.
10140 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10141 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10143 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10145 * fileio.c: Improve handling of file time marker. (Bug#11852)
10146 (special_mtime): New function.
10147 (Finsert_file_contents, Fverify_visited_file_modtime):
10148 Use it to set special mtime values consistently.
10150 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10152 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10153 marker for non-existing file. (Bug#11852)
10155 2012-07-03 Glenn Morris <rgm@gnu.org>
10157 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10158 and did not make it into globals.h).
10160 2012-07-03 Tom Tromey <tromey@redhat.com>
10162 * window.c (Fset_window_margins, Fset_window_fringes)

10190 * dosfns.c (system_process_attributes): Remove EXFUN.
10191 * keymap.h: Remove EXFUNs.
10192 * lisp.h: Remove EXFUNs.
10193 * w32term.h: Remove EXFUNs.
10194 * window.h: Remove EXFUNs.
10195 * xsettings.h: Remove EXFUN.
10196 * xterm.h: Remove EXFUN.
10198 2012-07-03 Glenn Morris <rgm@gnu.org>
10200 * lisp.h (Frandom): Make it visible to C.
10201 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
10202 buffer for invisible buffers. (Bug#1229)
10204 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10206 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
10207 values which aren't power of 2.
10208 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10209 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
10212 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
10214 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
10216 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10218 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10220 * alloc.c (allocate_vector_block): Remove redundant
10221 calls to mallopt if DOUG_LEA_MALLOC is defined.
10222 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10223 avoid calls to mallopt if zero_vector is returned.
10225 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10227 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10228 is enabled, avoid dereferencing NULL current_sblock if
10231 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10233 Cleanup basic buffer management.
10234 * buffer.h (struct buffer): Change layout to use generic vector
10235 marking code. Fix some comments. Change type of 'clip_changed'
10236 to bitfield. Remove unused #ifndef old.
10237 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10238 (GET_OVERLAYS_AT): Fix indentation.
10239 (for_each_per_buffer_object_at): New macro.
10240 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

10244 struct buffer. Fix comment.
10245 (mark_overlay): New function.
10246 (mark_buffer): Use it. Use mark_vectorlike to mark normal
10247 Lisp area of struct buffer.
10248 (mark_object): Use it. Adjust marking of misc objects
10249 and related comments.
10251 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10253 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10254 wrapper that is not needed because the wrapped code is a no-op (zero
10255 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10256 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10258 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10260 * alloc.c (mark_buffer): Simplify. Remove prototype.
10261 (mark_object): Add comment. Reorganize marking of vector-like
10262 objects. Use CHECK_LIVE for all vector-like objects except buffers
10263 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10264 Avoid redundant calls to mark_vectorlike for bool vectors.
10266 2012-06-30 Glenn Morris <rgm@gnu.org>
10268 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10270 * epaths.in (PATH_SITELOADSEARCH): New.
10271 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10272 This is rather than relying on --enable-locallisppath elements
10273 having "site-lisp" in their names. (Bug#10208#25, 11658)
10275 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10277 * w32proc.c (sys_select): Accept and ignore one more argument.
10279 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10281 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10282 (pselect) [!MS_DOS]: Redirect to sys_select.
10284 * sysdep.c: Don't include dos.h and dosfns.h.
10286 * process.c (sys_select):
10287 * msdos.c (sys_select): Accept one more argument and ignore it.
10289 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10290 adapt data types and code to that.
10293 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10294 which clashes with the gnulib function of the same name.
10296 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10298 * font.c (font_style_to_value, font_style_symbolic)
10299 (font_prop_validate_style): Add type checks for values in
10302 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10304 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10307 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10309 * xdisp.c (try_window_id): Undo last change.
10311 * w32.c (getwd): Adjust commentary about startup_dir.
10312 (init_environment): Always call sys_access, even in non-MSVC
10313 builds. Don't chdir to the directory of the Emacs executable.
10314 This undoes code from 1997 which was justified by the need to
10315 "avoid conflicts when removing and renaming directories". But its
10316 downside was that every relative file name was being interpreted
10317 relative to the directory of the Emacs executable, which can never
10318 be TRT. In particular, it broke sys_access when called with
10319 relative file names.
10320 (sys_access): Map GetLastError to errno.
10322 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10324 * window.h (struct window): Change type of 'fringes_outside_margins'
10325 to bitfield. Fix comment. Adjust users accordingly.
10326 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
10328 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10331 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
10333 * gnutls.c (emacs_gnutls_handshake):
10334 Add QUIT to make the loop interruptible.
10336 2012-06-29 Glenn Morris <rgm@gnu.org>
10338 * charset.c (init_charset): Make lack of etc/charsets fatal.
10340 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10342 * editfns.c (region_limit): Fix type mismatch.
10344 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10346 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
10347 undefined. Convert from xassert to eassert.
10348 * nsmenu.m: Convert from xassert to eassert.
10349 * nsterm.m: Likewise.
10351 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
10353 * editfns.c (region_limit): Clip to narrowing (bug#11770).
10355 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
10357 Avoid integer overflow on scroll-left and scroll-right.
10358 * window.c (HSCROLL_MAX): New macro.
10359 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
10360 overflow when requested scroll falls outside ptrdiff_t range.
10362 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10364 * window.h (struct window): Change type of 'hscroll',
10365 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
10366 'last_modified' and 'last_overlay_modified' to EMACS_INT.
10367 Adjust users accordingly.
10368 * xdisp.c (try_cursor_movement): Replace type check with eassert.
10369 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
10370 from EMACS_INT to ptrdiff_t.
10371 (make_window): Omit redundant initialization.
10373 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
10375 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
10377 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10379 * window.h (struct window): Change type of 'use_time' and

10514 Use sprintf return value instead of invoking strlen on result.
10515 In the old days this wasn't portable, since some sprintf
10516 implementations returned char *. But they died out years ago and
10517 Emacs already assumes sprintf returns int.
10518 Similarly for float_to_string.
10519 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

10527 Use sprintf or float_to_string result to avoid need to call strlen.
10528 * data.c (Fnumber_to_string):
10529 Use make_unibyte_string, since the string must be ASCII.
10530 * lisp.h, print.c (float_to_string): Now returns int length.
10531 * term.c (produce_glyphless_glyph):
10532 Use sprintf result rather than recomputing it.
10534 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

10565 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10567 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

10570 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10572 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10573 instead of truncating it to 63 (admittedly a generous limit).

10632 * dispnew.c (Fsleep_for, sit_for):
10633 * keyboard.c (kbd_buffer_get_event):
10634 * process.c (Faccept_process_output):
10635 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10636 This improves on the previous patch, which introduced a bug
10637 when time_t is unsigned and as wide as intmax_t.
10638 See <http://bugs.gnu.org/9000#51>.
10640 2012-06-23 Eli Zaretskii <eliz@gnu.org>

10666 last argument of make_unibyte_string.
10668 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
10669 language ID in the event parameters.
10671 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10672 event.code, not the obscure "character set ID".
10674 2012-06-23 Chong Yidong <cyd@gnu.org>
10676 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

10703 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10705 Support higher-resolution time stamps (Bug#9000).
10706 The time stamps are only nanosecond-resolution at the C level,
10707 since that's the best that any real-world system supports now.
10708 But they are picosecond-resolution at the Lisp level, as that's
10709 easy, and leaves room for future OS improvements.
10711 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10714 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10715 Don't get current time unless it's needed.
10717 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10718 now provides it if it's absent.
10719 (start_atimer): Port to higher-res time stamps.
10720 Check for time stamp overflow. Don't get current time more
10721 often than is needed.
10723 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10724 Include systime.h, not time.h.
10725 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10727 * dired.c: Include stat-time.h.
10728 (Ffile-attributes): File times now have higher resolution.
10730 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10731 (struct image): Timestamp now has higher resolution.
10733 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10734 has at least microseconds now. All uses removed.
10735 (update_frame, update_single_window, update_window, update_frame_1)
10736 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10737 (duration_to_sec_usec): Remove; no longer needed.
10739 * editfns.c (time_overflow): Now extern.
10740 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10741 (float-time, Fformat_time_string, Fcurrent_time_string)
10742 (Fcurrent_time_zone): Accept and generate higher-resolution
10744 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
10745 (decode_time_components, lisp_seconds_argument): New functions.
10746 (make_time): Now static.
10747 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10748 Report an error if the time is invalid, rather than having the caller
10751 * fileio.c: Include <stat-time.h>
10752 (Fcopy_file): Copy higher-resolution time stamps.
10753 Prefer to set the time stamp via a file descriptor if that works.
10754 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10755 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10756 (Fvisited_file_modtime, Fset_visited_file_modtime):
10757 Support higher-resolution time stamps.
10759 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10761 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10763 * image.c (prepare_image_for_display, clear_image_cache)
10764 (lookup_image): Port to higer-resolution time stamps.
10766 * keyboard.c (start_polling, bind_polling_period):
10767 Check for time stamp overflow.
10768 (read_char, kbd_buffer_get_event, timer_start_idle)
10769 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10770 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10771 Port to higher-resolution time stamps. Do not assume time_t is signed.
10772 (decode_timer): New function. Timers are now vectors of length 9,
10773 not 8, to accommodate the picosecond component.
10774 (timer_check_2): Use it.
10776 * nsterm.m (select_timeout, timeval_subtract): Remove.
10777 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10778 as they're a bit more accurate and handle overflow better.
10779 (ns_select): Change prototype to be compatible with pselect.
10780 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10781 * nsterm.h (ns_select): Adjust prototype.
10783 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10784 us-resolution time stamps.
10785 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10787 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10789 * lisp.h (time_overflow): New decl.
10790 (wait_reading_process_output): First arg is now intmax_t, not int,
10791 to accommodate larger waits.
10793 * process.h (struct Lisp_Process.read_output_delay):
10794 Now counts nanoseconds, not microseconds.
10795 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10797 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10798 (wait_reading_process_output):
10799 Port to ns-resolution time stamps.
10800 (Faccept_process_output, wait_reading_process_output):
10801 Check for time stamp overflow. Do not assume time_t is signed.
10802 (select_wrapper): Remove; we now use pselect.
10803 (Fprocess_attributes): Now generates ns-resolution time stamps.
10805 * sysdep.c: Include utimens.h. Don't include utime.h
10806 or worry about struct utimbuf; gnulib does that for us now.
10807 (gettimeofday): Remove; gnulib provides a substitute.
10808 (make_timeval): New function.
10809 (set_file_times): Now sets ns-resolution time stamps.
10810 New arg FD; all uses changed.
10811 (time_from_jiffies, ltime_from_jiffies, get_up_time)
10812 (system_process_attributes):
10813 Now returns ns-resolution time stamp. All uses changed.
10814 Check for time stamp overflow.
10816 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10817 provides a substitute now.
10819 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10820 since it guarantees struct timespec.
10821 (EMACS_TIME): Now struct timespec, so that we can support
10822 ns-resolution time stamps.
10823 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10824 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10825 (EMACS_USECS): Remove.
10826 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10827 so multiply the arg by 1000 before storing it.
10828 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10830 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
10831 Port to ns-resolution time stamps.
10832 (EMACS_TIME_NEG_P): Remove; replaced by....
10833 (EMACS_TIME_SIGN): New macro.
10834 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
10835 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
10836 (set_file_times, make_time, lisp_time_argument): Adjust signature.
10837 (make_timeval, make_lisp_time, decode_time_components): New decls.
10838 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10839 that it mishandled time_t overflow. You can't compare by subtracting!
10840 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10841 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10843 * term.c: Include <sys/time.h>.

10880 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10881 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10882 staticidx goes up to 1597 out of 1600 = 0x640.)
10884 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10886 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.

10919 Port byte-code-meter to modern targets.
10920 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10921 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10922 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in

10932 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10933 gets killed during executing of this function (Bug#11665).

10960 * lisp.h (eassert): Assume C89 or later.
10961 This removes the need for CHECK.

11284 (roundup_size): New constant.
11285 (struct vector_block): New data type.
11286 (vector_blocks, vector_free_lists, zero_vector): New variables.

11289 (sweep_vectors): New functions.
11290 (allocate_vectorlike): Return `zero_vector' as the only vector of
11291 0 items. Allocate new vector from block if vector size is less than
11292 or equal to VBLOCK_BYTES_MAX.
11293 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
11294 (init_alloc_once): Add call to init_vectors.
11296 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
11298 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
11300 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
11302 * doprnt.c (doprnt): Truncate multibyte char correctly.
11303 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
11304 would mishandle a string argument "Xc" if X was a multibyte
11305 character of length 2: it would truncate after X's first byte
11306 rather than including all of X.
11308 2012-06-06 Chong Yidong <cyd@gnu.org>
11310 * buffer.c (word_wrap): Doc fix.
11312 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

11324 binary via PaX flags if the paxctl utility is available.
11325 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
11326 Restore PaX flags to their default. (Bug#11398)
11328 2012-06-03 Chong Yidong <cyd@gnu.org>
11330 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
11331 buffer (Bug#11226).

11335 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
11336 (note_mode_line_or_margin_highlight): If there is no help echo,
11337 use mode-line-default-help-echo. Handle the case where the mouse
11338 position is past the end of the mode line string.
11340 * buffer.c (buffer_local_value_1): New function, split from
11341 Fbuffer_local_value; can return Qunbound.
11342 (Fbuffer_local_value): Use it.
11343 (Vmode_line_format): Docstring tweaks.
11345 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
11347 * sysdep.c (system_process_attributes): Improve comment.
11349 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
11351 * keyboard.c: Export real-this-command to Elisp.
11352 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
11353 and DEFVAR it. Update all users.
11355 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
11357 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11359 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11360 Convert pctcpu and pctmem to Lisp float properly.
11361 Let the compiler fold better, as 100.0/0x8000 is exact.
11363 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11365 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
11368 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
11370 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
11372 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
11374 For a 'struct window', replace some Lisp_Object fields to
11375 bitfields where appropriate, remove unused fields.
11376 * window.h (struct window): Remove unused 'last_mark_x' and
11377 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11378 change its type from Lisp_Object to bitfield.
11379 Change type of 'force_start', 'optional_new_start',
11380 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
11381 fields from Lisp_Object to bitfield. Adjust users accordingly.
11383 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11385 Pacify gcc -Wdouble-precision when using Xaw.
11386 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11387 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11388 Use 'float' consistently, rather than 'float' in most places
11389 and 'double' in a couple of places.
11391 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11393 * xdisp.c (handle_stop): Detect whether we have overlay strings
11394 loaded by testing it->current.overlay_string_index to be
11395 non-negative, instead of checking whether n_overlay_strings is
11396 positive. (Bug#11587)
11398 2012-05-31 Chong Yidong <cyd@gnu.org>
11400 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
11402 * doc.c (Fsubstitute_command_keys): Doc fix.
11404 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11406 * search.c (search_buffer): Remove calls to
11407 r_alloc_inhibit_buffer_relocation, as it is now called by
11408 maybe_unify_char, which was the cause of relocation of buffer text
11411 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11413 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11414 for the duration of call to load_charset, to avoid problems with
11415 callers of maybe_unify_char that access buffer text through C
11418 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11419 decrement the inhibition flag, instead of just setting or
11422 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11424 Remove obsolete '#define static' cruft.
11425 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11426 This #undef was "temporary" in 2000; it is no longer needed
11427 now that '#define static' has gone away.
11428 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11429 (gray_bitmap_bits): Remove; no longer needed.
11430 All uses replaced with definiens.
11431 * xterm.c: Include "bitmaps/gray.xbm".
11433 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
11435 Clean up __executable_start, monstartup when --enable-profiling.
11436 The following changes affect the code only when profiling.
11437 * dispnew.c (__executable_start): Rename from safe_bcopy.
11438 Define only on platforms that need it.
11439 * emacs.c: Include <sys/gmon.h> when profiling.
11440 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
11441 (__executable_start): Remove decl, since lisp.h does it now.
11442 (safe_bcopy): Remove decl; no longer has that name.
11443 (main): Coalesce #if into single bit of code, for simplicity.
11444 Cast pointers to uintptr_t, since standard libraries want integers
11446 * lisp.h (__executable_start): New decl.
11448 2012-05-31 Glenn Morris <rgm@gnu.org>
11450 * image.c (Fimagemagick_types): Doc fix.
11452 2012-05-30 Jim Meyering <meyering@redhat.com>
11454 * callproc.c (Fcall_process_region): Include directory component

11467 (Qdefun): Move from eval.c.
11468 * lisp.h (Qdefun): Remove.
11469 * lread.c (read1): Tiny simplification.
11471 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
11473 Do not create empty overlays with the evaporate property (Bug#9642).
11474 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11475 Bug#9642, but explicitly check that the buffer the overlay would
11476 be moved to is live and rearrange lines to make sure that errors
11477 will not put the overlay in an inconsistent state.
11478 (Fdelete_overlay): Cosmetics.
11480 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11482 * w32term.c (my_bring_window_to_top): New function.
11483 (x_raise_frame): Use handle returned by DeferWindowPos, which
11484 could be different from the original one.
11485 Call my_bring_window_to_top instead of my_set_foreground_window.
11488 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP

11494 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11496 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11497 This avoids undefined behavior that might cause the eassert
11498 to not catch an out-of-range value.
11500 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11502 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
11503 Update dependencies.
11505 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11507 * bidi.c (bidi_mirror_char): Fix last change.
11509 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

11514 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11516 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11517 Only r_alloc_inhibit_buffer_relocation needed to be added;
11518 the others were already declared.
11520 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11521 before checking whether it's out of range. Put the check inside
11523 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11525 2012-05-27 Ken Brown <kbrown@cornell.edu>
11527 * callproc.c (Fcall_process): Restore a line that was accidentally
11528 commented out in the 2011-02-13 change (bug#11547).
11530 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11532 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11533 defined on ralloc.c.
11535 * buffer.c [REL_ALLOC]: Remove prototypes of
11536 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11537 they are now on lisp.h.
11539 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11541 * search.c (search_buffer): Use it to inhibit relocation of buffer
11542 text while re_search_2 is doing its job, because re_search_2 is
11543 passed C pointers to buffer text. (Bug#11519)
11545 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11546 Update value to 24.
11548 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11549 state after an additional call to move_it_in_display_line_to, keep
11550 the values of it->max_ascent and it->max_descent found for the
11552 (pos_visible_p): Revert the comparison against bottom_y to what it
11553 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11556 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11558 Fix coding-related core dumps with gcc -ftrapv.
11559 The code was computing A - B, where A and B are pointers, and B is
11560 random garbage. This can lead to core dumps on platforms that
11561 have special pointer registers, and it also leads to core dumps on
11562 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11563 A - B only when B is initialized properly.
11564 * coding.c (coding_set_source, coding_set_destination): Return void.
11565 (coding_change_source, coding_change_destinations): New functions,
11566 with the old behaviors of coding_set_source and coding_set_destination.
11567 All callers that need an offset changed to use these new functions.
11569 2012-05-26 Glenn Morris <rgm@gnu.org>
11571 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
11573 2012-05-26 Eli Zaretskii <eliz@gnu.org>

11576 * xdisp.c (draw_row_with_mouse_face):
11577 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11579 * w32console.c: Include window.h.
11580 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11582 (initialize_w32_display): Initialize mouse-highlight data.
11584 * w32inevt.c: Include termchar.h and window.h.
11585 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11586 moves, call note_mouse_highlight. If help_echo changed, call
11587 gen_help_event to produce help-echo message in the echo area.
11588 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11591 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11593 * lread.c (read1): Simplify slightly to avoid an overflow warning
11594 with GCC 4.7.0 on x86-64.
11596 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11598 * bidi.c (bidi_mirror_char): Revert last change: an int is
11599 definitely wide enough here.
11601 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
11603 Fix integer width and related bugs (Bug#9874).

11610 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
11611 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11613 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11614 (allocate_pseudovector):
11615 Use int, not EMACS_INT, where int is wide enough.
11616 (inhibit_garbage_collection, Fgarbage_collect):
11617 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11618 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11619 int might not be wide enough.

11622 (bidi_at_paragraph_end, bidi_find_paragraph_start)
11623 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
11624 (bidi_level_of_next_char, bidi_move_to_visually_next):
11625 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11626 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
11627 (Fkill_buffer, Fset_buffer_major_mode)
11628 (advance_to_char_boundary, Fbuffer_swap_text)

11635 (Foverlay_recenter, last_overlay_modification_hooks_used)
11636 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11637 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11638 (validate_region): Omit unnecessary test for b <= e,
11639 since that's guaranteed by the previous test.
11640 (adjust_overlays_for_delete): Avoid pos + length overflow.
11641 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11642 (report_overlay_modification):
11643 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11644 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11645 Omit pointer cast, which isn't needed anyway, and doesn't work
11646 after the EMACS_INT -> ptrdiff_t change.
11647 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11648 * buffer.h: Adjust decls to match defn changes elsewhere.
11649 (struct buffer_text, struct buffer):
11650 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11651 Use EMACS_INT, not int, where int might not be wide enough.
11652 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11653 not int, to avoid needless 32-bit limit on 64-bit hosts.
11654 (exec_byte_code): Use tighter memory-full test, one that checks
11655 for alloca overflow. Don't compute the address of the object just
11656 before an array, as that's not portable. Use EMACS_INT, not
11657 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11658 * callint.c (Fcall_interactively):
11659 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11660 * callproc.c (call_process_kill, Fcall_process):
11661 Don't assume pid_t fits into an Emacs fixnum.

11670 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11671 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11672 (casify_object): Avoid integer overflow when overallocating buffer.
11673 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11674 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11675 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11676 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11677 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11678 integers are now checked earlier. All uses replaced with XINT.
11680 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11681 For CCL_MapSingle, check that content and value are in int range.

11683 Check that Vcode_version_map_vector is a vector.
11684 (resolve_symbol_ccl_program): Check that vector header is in range.
11685 Always copy the vector, so that we can check its contents reliably
11686 now rather than having to recheck each instruction as it's being
11687 executed. Check that vector words fit in 'int'.
11688 (ccl_get_compiled_code, Fregister_ccl_program)
11689 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11690 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11691 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11692 contents are in range.
11693 (Fccl_execute_on_string): Check that status is in range.
11694 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11695 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11696 Accept and return EMACS_INT, not int, because callers can pass values
11697 out of 'int' range.

11703 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11716 Don't rely on undefined behavior with signed left shift overflow.
11717 Don't assume unsigned int fits into fixnum, or that fixnum fits
11718 into unsigned int. Don't require max_code to be a valid fixnum;
11719 that's not true for gb10830 4-byte on a 32-bit host. Allow

11721 to be a character. Avoid int overflow if max_char is close

11733 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11734 where the argument is EMACS_INT, and this behavior is not intended.

12378 * xmenu.c (Fx_popup_dialog, set_frame_menubar)
12379 (create_and_show_popup_menu, create_and_show_dialog, xmenu_show):
12380 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12381 * xml.c (parse_region):
12382 * xrdb.c (magic_file_p):
12383 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12384 * xselect.c (TRACE1): Don't assume pid_t promotes to int.
12385 (x_get_local_selection, x_reply_selection_request)
12386 (x_handle_selection_request, wait_for_property_change):
12387 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12388 (selection_data_to_lisp_data): Use short, not EMACS_INT, where
12389 short is wide enough.
12390 (x_send_client_event): Don't assume fixnum fits in int.
12391 * xterm.c (x_x_to_emacs_modifiers):
12392 Don't assume EMACS_INT overflows nicely into int.
12393 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
12394 may come from Lisp.
12395 (handle_one_xevent): NATNUMP can eval its arg twice.
12396 (x_connection_closed):
12397 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12398 * xterm.h: Adjust decls to match defn changes elsewhere.
12399 (struct scroll_bar): Use struct vectorlike_header
12400 rather than rolling our own approximation.
12401 (SCROLL_BAR_VEC_SIZE): Remove; not used.
12403 2012-05-25 Glenn Morris <rgm@gnu.org>
12405 * lisp.mk (lisp): Update for more files being compiled now.
12407 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
12409 * lread.c: Remove `read_pure' which makes no difference.
12410 (read_pure): Remove var.
12411 (unreadpure): Remove function.
12412 (readevalloop): Don't call read_list with -1 flag.
12413 (read1, read_vector): Don't test read_pure any more.
12414 (read_list): Simplify.
12416 * fileio.c, character.h: Minor style tweaks.
12418 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
12420 * window.h (clip_changed): Remove useless declaration.
12422 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
12424 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
12425 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
12427 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
12430 This directory predates autoconf and is no longer needed nowadays.
12431 Move its few remaining bits of functionality to where they're needed.
12432 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
12433 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
12434 * m/template.h: Remove.
12435 * Makefile.in (M_FILE): Remove. All uses removed.
12436 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
12437 * lisp.h (USE_LSB_TAG):
12438 * mem-limits.h (EXCEEDS_LISP_PTR):
12439 Use VAL_MAX, not VALBITS, in #if.
12440 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
12441 (EMACS_UINT): Define unconditionally now.
12442 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
12443 (BITS_PER_EMACS_INT): New constants, replacing
12444 what used to be in config.h, but not useful in #if.
12445 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
12446 define them any more.
12447 (VAL_MAX): New macro.
12449 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
12450 BITS_PER_EMACS_INT, in #if.
12451 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
12452 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
12453 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
12454 * s/ms-w32.h (DATA_START):
12455 Move here from removed file m/intel386.h.
12456 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
12457 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
12459 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
12461 Assume C89 or later.
12462 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
12463 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
12465 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
12466 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
12467 * textprop.c, tparam.c (NULL): Remove.
12468 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
12469 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
12470 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
12471 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
12472 * xterm.c (input_signal_count): Assume volatile works.
12474 2012-05-21 Ken Brown <kbrown@cornell.edu>
12476 * xgselect.c (xg_select): Fix first argument in call to 'select'
12479 2012-05-20 Ken Brown <kbrown@cornell.edu>
12481 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
12482 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
12484 2012-05-19 Ken Brown <kbrown@cornell.edu>
12486 * xfns.c (x_in_use): Remove `static' qualifier.
12487 * xterm.h (x_in_use): Declare.
12488 * xgselect.c: Include xterm.h.
12489 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
12490 and `display_arg' (bug#9754).
12492 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
12494 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
12496 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
12497 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
12499 2012-05-18 Eli Zaretskii <eliz@gnu.org>
12501 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
12503 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
12504 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
12506 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12507 reference to image_cache->refcount.
12508 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12510 2012-05-17 Juri Linkov <juri@jurta.org>
12512 * search.c (Fword_search_regexp, Fword_search_backward)
12513 (Fword_search_forward, Fword_search_backward_lax)
12514 (Fword_search_forward_lax): Move functions to isearch.el
12515 (bug#10145, bug#11381).
12517 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12519 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12521 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12523 * lread.c (init_obarray): Declare Qt and Qnil as special.
12525 2012-05-14 Glenn Morris <rgm@gnu.org>
12527 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12528 Put "libexec" before "bin", for the sake of init_callproc_1.
12530 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12532 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12534 * unexaix.c: Port to more-recent AIX compilers.
12535 (report_error, report_error_1, make_hdr, copy_sym)
12536 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12537 Make arguments const char *, not char *, to avoid violations of C
12538 standard and to fix some AIX warnings reported by Gilles Pion.
12540 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12542 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12543 already have overlays loaded.
12544 (handle_single_display_spec): Before returning without displaying
12545 fringe bitmap, synchronize the bidi iterator with the main display
12546 iterator, by calling iterate_out_of_display_property.
12547 (iterate_out_of_display_property): Detect buffer iteration by
12548 testing that it->string is a Lisp string.
12549 (get_next_display_element): When the current object is exhausted,
12550 and there's something on it->stack, call set_iterator_to_next to
12551 proceed with what's on the stack, instead of returning zero.
12552 (set_iterator_to_next): If called at the end of a Lisp string,
12553 proceed to consider_string_end without incrementing string
12554 position. Don't increment display vector index past the end of
12555 the display vector. (Bug#11417)
12556 (pos_visible_p): Don't report a position visible when move_it_to
12557 stopped at the last line of window, which happens to be scanned
12558 backwards by the bidi iteration. (Bug#11464)
12560 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12562 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12563 and right-margin display specs even if the spec is invalid or we
12564 are on a TTY, and thus unable to display on the fringes.
12565 That's because the text with the property will not be displayed anyway,
12566 so we need to signal to the caller that this is a "replacing"
12567 display spec. This fixes display when the spec is invalid or we
12570 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12572 * unexaix.c (make_hdr): Fix typo in prototype.
12573 This bug broke the build on AIX. Problem reported by Gilles Pion.
12575 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12577 * keyboard.c (kbd_buffer_get_event): Read special events also in
12578 batch mode. (Bug#11415)
12580 2012-05-12 Glenn Morris <rgm@gnu.org>
12582 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12584 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12586 * lisp.mk (lisp): Add newcomment.elc.
12588 2012-05-12 Glenn Morris <rgm@gnu.org>
12590 * Makefile.in (MKDIR_P): New, set by configure.
12591 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12593 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12595 Remove unused function hourglass_started.
12596 * dispextern.h (hourglass_started):
12597 * w32fns.c (hourglass_started):
12598 * xdisp.c (hourglass_started): Remove.
12600 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12602 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12603 Update dependencies.
12605 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12607 * xgselect.c (xg_select): Put maxfds+1 into a var.
12608 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12610 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12612 2012-05-10 Dave Abrahams <dave@boostpro.com>
12614 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12615 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12617 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12619 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12620 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12621 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12622 Initialize xd_registered_buses.
12624 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12626 Untag more efficiently if USE_LSB_TAG.
12627 This is based on a proposal by YAMAMOTO Mitsuharu in
12628 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12629 For an admittedly artificial (nth 8000 longlist) benchmark on
12630 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12631 Emacs's overall text size by 1%.
12632 * lisp.h (XUNTAG): New macro.
12633 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12634 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12635 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12636 * eval.c (Fautoload):
12637 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12638 * frame.h (XFRAME): Use XUNTAG.
12640 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12641 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12642 Remove unportable assumptions about print widths of types like
12644 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12645 intptr_t when converting between pointer and integer, to avoid GCC
12646 warnings about wrong width.
12648 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12650 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12651 stack for each reader_thread, instead of defaulting to 8MB
12652 determined by the linker. This avoids failures in creating
12653 subprocesses on Windows 7, see the discussion in this thread:
12654 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12656 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12658 Fix up display of the *Minibuf-0* buffer in the mini window.
12659 * keyboard.c (read_char): Don't clear the echo area if there's no
12661 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12662 contents of *Minibuf-0*) if there's no message displayed in its stead.
12664 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12666 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12669 2012-05-06 Chong Yidong <cyd@gnu.org>
12671 * lisp.mk (lisp): Update.
12673 2012-05-05 Jim Meyering <meyering@redhat.com>
12675 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12677 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12679 * data.c (PUT_ERROR): New macro.
12680 (syms_of_data): Use it. Add new error type `user-error'.
12681 * undo.c (user_error): New function.
12682 (Fprimitive_undo): Use it.
12683 * print.c (print_error_message): Adjust print style for `user-error'.
12684 * keyboard.c (user_error): New function.
12685 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12687 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12689 Do not limit current-time-string to years 1000..9999.
12690 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12691 (Fcurrent_time_string): Support any year that is supported by the
12692 underlying localtime representation. Don't use asctime, as it
12693 has undefined behavior for years outside the range -999..9999.
12695 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12697 Fix race conditions involving setenv, gmtime, localtime, asctime.
12698 Without this fix, interrupts could mess up code that uses these
12699 nonreentrant functions, since setting TZ invalidates existing
12700 tm_zone or tzname values, and since most of these functions return
12701 pointers to static storage.
12702 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12703 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12704 Grow the critical sections to include not just invoking
12705 localtime/gmtime, but also accessing these functions' results
12706 including their tm_zone values if any, and any related TZ setting.
12707 (format_time_string): Last arg is now struct tm *, not struct tm **,
12708 so that the struct tm is saved in the critical section.
12709 All callers changed. Simplify allocation of initial buffer, partly
12710 motivated by the fact that memory allocation needs to be outside
12711 the critical section.
12713 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12715 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12716 with RESET_INTERVAL.
12718 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12719 Remove duplicated buffer name initialization.
12721 2012-05-02 Jim Meyering <jim@meyering.net>
12723 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12725 * xfns.c (x_window): Use xstrdup (Bug#11375).
12727 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12729 * xdisp.c (pos_visible_p): If already at a newline from the
12730 display string before the 'while' loop, don't walk back the glyphs
12731 from it3.glyph_row. Solves assertion violation when the display
12732 string begins with a newline (egg.el). (Bug#11367)
12734 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12736 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12739 2012-05-01 Glenn Morris <rgm@gnu.org>
12741 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12742 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12743 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12744 All were removed before 23.1.
12746 * dispnew.c: Remove HAVE_LIBNCURSES test;
12747 it is always true on relevant platforms.
12749 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12750 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12752 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12754 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12756 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12757 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12760 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12762 Do not avoid creating empty evaporating overlays (Bug#9642).
12763 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12764 That is, do not delete an evaporating overlay if it becomes
12765 empty after its bounds are adjusted to fit within its buffer.
12766 This fix caused other problems, and I'm reverting it until we get
12767 to the bottom of them.
12769 2012-04-27 Chong Yidong <cyd@gnu.org>
12771 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12773 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12775 * xdisp.c (pos_visible_p): If the window start position is beyond
12776 ZV, start the display from buffer beginning. Prevents assertion
12777 violation in init_iterator when the minibuffer window is scrolled
12778 via the scroll bar.
12780 * window.c (window_scroll_pixel_based): Likewise.
12782 2012-04-27 Chong Yidong <cyd@gnu.org>
12784 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12786 2012-04-27 Glenn Morris <rgm@gnu.org>
12788 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12789 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12791 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12793 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12794 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12796 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12798 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12799 display element, check also the underlying string or buffer
12800 character. (Bug#11341)
12802 * w32menu.c: Include w32heap.h.
12803 (add_menu_item): If the call to AppendMenuW (via
12804 unicode_append_menu) fails, disable Unicode menus only if we are
12805 running on Windows 9X/Me.
12807 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12809 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12810 (xgetint): Add missing shift for LSB tags.

12814 * keyboard.c (read_char): Don't wipe echo area for select window

12830 Do not create empty overlays with the evaporate property (Bug#9642).
12831 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12832 if it becomes empty after its bounds are adjusted to fit within
12833 its buffer. Without this fix, in a nonempty buffer (let ((o
12834 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12835 yields an empty overlay that has the evaporate property, which is
12836 not supposed to happen.
12838 Fix minor GTK3 problems found by static checking.
12839 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

12859 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12860 (__malloc_size_t, __malloc_ptrdiff_t):
12861 Remove. All uses removed, replaced by the definiens if needed,
12862 since we can assume C89 or better now.

12951 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12953 * sysdep.c [__FreeBSD__]: Minor cleanups.
12954 (list_system_processes, system_process_attributes) [__FreeBSD__]:
12955 Use Emacs indenting style more consistently. Avoid some casts.
12956 Use 'double' consistently rather than mixing 'float' and 'double'.

12967 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
12969 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
12970 It is never used otherwise.
12972 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
12974 * print.c (print_preprocess): Only check print_depth if print-circle

12981 * process.c (wait_reading_process_output): If EIO occurs on a pty,
12982 set the status to "failed" and ensure that sentinel is run.
12984 2012-04-20 Glenn Morris <rgm@gnu.org>
12986 * process.c (Fset_process_inherit_coding_system_flag)
12987 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

13037 New extern decls, to avoid calling undeclared functions.
13038 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
13039 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
13040 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13041 (NEED_MEM_INSERT): New macro.
13042 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13043 Remove one incorrect comment and fix another.

13079 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
13080 * s/netbsd.h, s/sol2-6.h:
13081 Remove definition of GC_MARK_STACK, since the default now works.
13082 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

13110 2012-04-11 Daniel Colascione <dancol@dancol.org>
13112 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13113 against is gone. It's better to use vfork now so that when Cygwin
13114 gains a new, working vfork, we use it automatically (bug#10398).
13116 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

13169 * minibuf.c (Fread_variable): Callers changed.
13171 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13173 * xdisp.c (set_cursor_from_row): If the display string appears in
13174 the buffer at position that is closer to point than the position
13175 after the display string, display the cursor on the first glyph of
13176 the display string. Fixes cursor display when a 'display' text
13177 property immediately follows invisible text. (Bug#11094)
13179 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13181 composite.c: use 'double' consistently
13182 * composite.c (get_composition_id): Use 'double' consistently
13183 instead of converting 'float' to 'double' and vice versa; this is
13184 easier to understand and avoids a GCC warning.
13186 2012-04-09 Glenn Morris <rgm@gnu.org>
13188 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13189 preparation for dumping it with emacs. (Bug#4789)

13233 [!WINDOWSNT]: New macros.
13234 (init_libxml2_functions, libxml2_loaded_p): New functions.
13235 (parse_region): Call fn_xmlCheckVersion instead of using the macro

13238 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13240 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13241 Call init_libxml2_functions before calling libxml2 functions.
13242 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13244 * emacs.c: Don't include libxml/parser.h.
13245 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
13246 xmlCleanupParser directly.
13248 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
13250 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13252 * indent.c (Fvertical_motion): If there is a display string at
13253 point, use it.vpos to compute how many lines to backtrack after
13254 move_it_to point. (Bug#11133)
13256 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13258 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13259 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13260 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13261 macros related to unification of CJK characters. For the details,
13262 see the discussion following the message here:
13263 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
13265 2012-04-04 Chong Yidong <cyd@gnu.org>
13267 * keyboard.c (Vdelayed_warnings_list): Doc fix.
13269 2012-04-01 Eli Zaretskii <eliz@gnu.org>
13271 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
13272 instead of alloca. (Bug#11138)
13274 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
13276 * w32menu.c (is_simple_dialog): Properly check lisp types.
13279 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13281 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13282 position we get to after a call to move_it_to fails the
13283 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13284 only if we wind up in a string from display property. (Bug#11063)
13286 * window.c (Fdelete_other_windows_internal): Invalidate the row
13287 and column information about mouse highlight, so that redisplay
13288 restores it after reallocating the glyph matrices. (Bug#7464)
13290 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13291 string comes from a `display' text property, use the buffer
13292 position of that property as if we actually saw that position in
13294 (move_it_by_lines): Remove the assertion that
13295 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13296 violated when there's a before-string at the beginning of a line.
13299 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13301 * xdisp.c (append_space_for_newline): If the default face was
13302 remapped, use the remapped face for the appended newline.
13303 (extend_face_to_end_of_line): Use the remapped default face for
13304 extending the face to the end of the line.
13305 (display_line): Call extend_face_to_end_of_line when the default
13306 face was remapped. (Bug#11068)
13308 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13310 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
13312 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13314 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
13316 2012-03-27 Glenn Morris <rgm@gnu.org>
13318 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
13321 2012-03-26 Kenichi Handa <handa@m17n.org>
13323 * dispextern.h (struct glyph): Fix previous change. Change the
13324 bit length of glyphless.ch to 25 (Bug#11082).
13326 2012-03-26 Chong Yidong <cyd@gnu.org>
13328 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13329 (command_loop_1): Use it; inhibit selection update for
13330 handle-select-window too (Bug#8996).
13332 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
13334 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13336 2012-03-25 Kenichi Handa <handa@m17n.org>
13338 * dispextern.h (struct glyph): Change the bit length of
13339 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13341 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13343 * s/ms-w32.h (tzname): Include time.h before redirecting to
13344 _tzname. Fixes the MSVC build. (Bug#9960)
13346 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
13348 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13351 * xterm.c (XTread_socket): Only modify handling_signal if
13352 !SYNC_INPUT. (Bug#11080)
13354 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13356 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13357 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13358 when fetching a multibyte character consumes more bytes than
13359 CHAR_BYTES returns, due to unification of CJK characters in
13360 string_char. (Bug#11073)
13362 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13364 * process.c (wait_reading_process_output): Handle pty disconnect
13365 by refraining from sending oneself a SIGCHLD (bug#10933).
13367 2012-03-22 Chong Yidong <cyd@gnu.org>
13369 * dispextern.h (struct it): New member string_from_prefix_prop_p.
13371 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
13372 Mark string as coming from a prefix property.
13373 (handle_face_prop): Use default face for prefix strings (Bug#4281).
13374 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
13376 2012-03-21 Chong Yidong <cyd@gnu.org>
13378 * xfaces.c (Vface_remapping_alist): Doc fix.
13380 2012-03-20 Eli Zaretskii <eliz@gnu.org>
13382 * w32proc.c (Fw32_set_console_codepage)
13383 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
13386 2012-03-20 Chong Yidong <cyd@gnu.org>
13388 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
13389 to reflect default non-nil value of redisplay-dont-pause.
13391 2012-03-19 Kenichi Handa <handa@m17n.org>
13393 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
13394 it fit in a valid range (Bug#11003).
13396 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13398 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13399 that is not from display property, accept the row as a "cursor
13400 row" if one of the string's character has a non-nil `cursor'
13401 property. Fixes cursor positioning when there are newlines in
13402 overlay strings, e.g. in icomplete.el. (Bug#11035)
13404 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13406 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13408 2012-03-12 Chong Yidong <cyd@gnu.org>
13410 * eval.c (inhibit_lisp_code): Rename from
13411 inhibit_window_configuration_change_hook; move from window.c.
13413 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13414 * window.c (run_window_configuration_change_hook)
13415 (syms_of_window): Callers changed.
13417 2012-03-11 Chong Yidong <cyd@gnu.org>
13419 * keymap.c (Fkey_description): Doc fix (Bug#9700).
13421 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
13423 2012-03-10 Chong Yidong <cyd@gnu.org>
13425 * frame.c (other_visible_frames): Don't assume the selected frame
13426 is visible (Bug#10955).
13428 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
13430 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
13432 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
13434 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
13435 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13438 2012-03-03 Glenn Morris <rgm@gnu.org>
13440 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13442 2012-03-02 Eli Zaretskii <eliz@gnu.org>
13444 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
13445 position past the first glyph_row that ends at ZV. (Bug#10902)
13446 (redisplay_window, next_element_from_string): Fix typos in
13448 (redisplay_window): Pass to move_it_vertically the margin in
13449 pixels, not in screen lines.
13451 2012-03-02 Glenn Morris <rgm@gnu.org>
13453 * buffer.c (buffer-list-update-hook): Doc fix.
13455 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13457 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13458 push_it before setting up the iterator for the first overlay
13459 string, even if we have an empty string loaded.
13460 (next_overlay_string): If there's an empty string on the iterator
13461 stack, pop the stack. (Bug#10903)
13463 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13465 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13466 Suggested by Stefan Monnier in
13467 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13468 * alloc.c (widen_to_Lisp_Object): New static function.
13469 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13470 and widening them to Lisp_Objects. This would work even if
13471 USE_LSB_TAG is defined and wide integers are used, which might
13472 happen in a future version of Emacs.
13474 2012-02-25 Chong Yidong <cyd@gnu.org>
13476 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13479 * xselect.c (Fx_selection_exists_p): Doc fix.
13480 (x_clipboard_manager_save_all): Print an informative message
13481 before saving to clipboard manager.
13483 2012-02-24 Chong Yidong <cyd@gnu.org>
13485 * keyboard.c (process_special_events): Handle all X selection
13486 requests in kbd_buffer, not just the next one (Bug#8869).
13488 2012-02-23 Chong Yidong <cyd@gnu.org>
13490 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13491 call when setting menu-bar-lines and tool-bar-lines parameters.
13492 (unwind_create_frame_1): New helper function.
13494 * window.c (inhibit_window_configuration_change_hook): New var.
13495 (run_window_configuration_change_hook): Obey it.
13496 (syms_of_window): Initialize it.
13498 2012-02-22 Chong Yidong <cyd@gnu.org>
13500 * xterm.c (x_draw_image_relief): Add missing type check for
13501 Vtool_bar_button_margin (Bug#10743).
13503 2012-02-21 Chong Yidong <cyd@gnu.org>
13505 * fileio.c (Vfile_name_handler_alist): Doc fix.
13507 * buffer.c (Fget_file_buffer): Protect against invalid file
13508 handler return value.
13510 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
13512 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
13513 when computing $valmask.
13515 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13516 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13517 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13518 It's useless in that case, and it can cause problems on hosts
13519 that allocate halves of EMACS_INT values separately.
13520 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13521 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13522 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13523 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13524 it avoids undefined behavior on hosts where shifting right by more
13525 than the word width has undefined behavior.
13527 2012-02-19 Chong Yidong <cyd@gnu.org>
13529 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13530 (Funhandled_file_name_directory, Ffile_name_as_directory)
13531 (Fdirectory_file_name, Fexpand_file_name)
13532 (Fsubstitute_in_file_name): Protect against invalid file handler
13533 return values (Bug#10845).
13535 2012-02-18 Eli Zaretskii <eliz@gnu.org>
13537 * .gdbinit (pitx): Fix incorrect references to fields of the
13540 2012-02-17 Chong Yidong <cyd@gnu.org>

13544 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
13546 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
13547 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
13549 2012-02-15 Chong Yidong <cyd@gnu.org>
13551 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
13552 marked as special. Also, starting docstrings with * is obsolete.
13554 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
13556 * gnutls.c (emacs_gnutls_write): Fix last change.
13558 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
13560 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
13563 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
13565 * keymap.c (Fsingle_key_description): Handle char ranges.
13567 2012-02-12 Chong Yidong <cyd@gnu.org>
13569 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13570 as that creates a dangerous corner case.
13572 * window.c (Fdelete_window_internal): Invalidate the mouse
13573 highlight (Bug#9904).
13575 2012-02-12 Glenn Morris <rgm@gnu.org>
13577 * xselect.c (Fx_own_selection_internal)
13578 (Fx_get_selection_internal, Fx_disown_selection_internal)
13579 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
13580 * nsselect.m (Fx_own_selection_internal)
13581 (Fx_disown_selection_internal, Fx_selection_exists_p)
13582 (Fx_selection_owner_p, Fx_get_selection_internal):
13583 Sync docs and argument specs with the xselect.c versions.
13585 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
13587 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
13589 2012-02-11 Eli Zaretskii <eliz@gnu.org>
13591 * w32select.c (Fx_selection_exists_p): Sync doc string and
13592 argument list with xselect.c. (Bug#10783)
13594 * w16select.c (Fx_selection_exists_p): Sync doc string and
13595 argument list with xselect.c. (Bug#10783)
13597 2012-02-10 Glenn Morris <rgm@gnu.org>
13599 * fns.c (Fsecure_hash): Doc fix.
13601 2012-02-09 Kenichi Handa <handa@m17n.org>
13603 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
13605 2012-02-07 Chong Yidong <cyd@gnu.org>
13607 * buffer.c (Fbuffer_local_variables)
13608 (buffer_lisp_local_variables): Handle unbound vars correctly;
13609 don't let Qunbound leak into Lisp.
13611 2012-02-07 Glenn Morris <rgm@gnu.org>
13613 * image.c (Fimagemagick_types): Doc fix.
13615 * image.c (imagemagick-render-type): Change it from a lisp object
13616 to an integer. Move the doc here from the lisp manual.
13617 Treat all values not equal to 0 the same.
13619 2012-02-06 Chong Yidong <cyd@gnu.org>
13621 * doc.c (store_function_docstring): Avoid applying docstring of
13622 alias to base function (Bug#2603).
13624 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>

13629 2012-02-04 Chong Yidong <cyd@gnu.org>
13631 * nsterm.m: Declare a global (Bug#10694).
13633 2012-02-04 Eli Zaretskii <eliz@gnu.org>
13635 * w32.c (get_emacs_configuration_options):
13636 Include --enable-checking, if specified, in the return value.
13638 2012-02-04 Martin Rudalics <rudalics@gmx.at>
13640 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
13641 after rounding frame sizes. (Bug#9723)
13643 2012-02-04 Eli Zaretskii <eliz@gnu.org>
13645 * keyboard.c (adjust_point_for_property): Don't position point
13646 before BEGV. (Bug#10696)
13648 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
13650 Handle overflow when computing char display width (Bug#9496).
13651 * character.c (char_width): Return EMACS_INT, not int.
13652 (char_width, c_string_width): Check for overflow when
13653 computing the width; this is possible now that individual
13654 characters can have unbounded width. Problem introduced
13655 by merge from Emacs 23 on 2012-01-19.
13657 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
13659 * dbusbind.c (Fdbus_register_method): Mention the return value
13660 :ignore in the docstring.
13662 2012-02-02 Glenn Morris <rgm@gnu.org>
13664 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.
13666 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

13672 2012-02-02 Kenichi Handa <handa@m17n.org>
13674 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
13675 0, do not call append_composite_glyph.
13677 2012-02-02 Kenichi Handa <handa@m17n.org>
13679 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
13681 (x_produce_glyphs): If the component of a composition is a null
13682 string, set it->pixel_width to 1 to avoid zero-width glyph.
13684 2012-02-01 Eli Zaretskii <eliz@gnu.org>
13686 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
13687 first 2 arguments are identical. This makes inserting large
13688 output from a subprocess an order of magnitude faster on
13689 MS-Windows, where all sbrk'ed memory is always contiguous.
13691 2012-01-31 Glenn Morris <rgm@gnu.org>
13693 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

14219 * xdisp.c (redisplay_window): If cursor row is not fully visible
14220 after recentering, and scroll-conservatively is set to a large
14221 number, scroll window by a few more lines to make the cursor fully
14222 visible and out of scroll-margin. (Bug#10105)
14223 (start_display): Don't move to the next line if the display should
14224 start at a newline that is part of a display vector or an overlay
14225 string. (Bug#10119)

14308 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
14309 is set, removing the need for VIRT_ADDRESS_VARIES.
14310 (PURE_P): Use a more-efficient implementation that needs just one
14311 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
14312 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
14313 to 4 (xorl, subq, cmpq, setbe).
14314 * alloc.c (pure): Always extern now, since that's the
14315 VIRT_ADDR_VARIES behavior.

14317 consistency with the new puresize.h.
14318 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
14319 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

14325 (erase_phys_cursor, update_window_cursor, show_mouse_face)
14326 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
14327 behave as if the cursor position were at the window margin.
14329 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14330 and the cursor position is out of bounds, behave as if the cursor
14331 position were at the window margin. (Bug#10075)
14333 2011-11-18 Chong Yidong <cyd@gnu.org>
14335 * window.c (Fwindow_combination_limit): Make first argument

14356 * xdisp.c (row_hash): New function, body extracted from
14357 compute_line_metrics.
14358 (compute_line_metrics): Call row_hash, instead of computing the
14361 * dispnew.c (verify_row_hash): Call row_hash for computing the
14362 hash code of a row, instead of duplicating code from xdisp.c.
14364 * dispextern.h (row_hash): Add prototype.
14366 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
14368 * frame.c (delete_frame): Don't delete the terminal when the last

14394 (Fsplit_window_internal, saved_window)
14395 (Fset_window_configuration, save_window_save): Rename all
14396 occurrences of window_nest to window_combination_limit.

14402 2011-11-14 Eli Zaretskii <eliz@gnu.org>
14404 * xdisp.c (display_line): Move the call to
14405 highlight_trailing_whitespace before the call to
14406 compute_line_metrics, since the latter needs to see the final
14407 faces of all the glyphs to compute ROW's hash value.
14408 Fixes assertion violations in row_equal_p. (Bug#10035)
14410 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
14412 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
14413 just return (bug#10044).

14417 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14418 with user-defined heap size. Bump the default size of the temacs

14422 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
14423 current_matrix and desired_matrix. (Bug#9990)
14424 (verify_row_hash) [XASSERTS]: New function.

14469 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
14471 Avoid some portability problems by eschewing 'extern inline' functions.
14472 The trivial performance wins aren't worth the portability hassles; see
14473 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14475 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

14481 making these static again.
14482 (offset_intervals, temp_set_point_both, temp_set_point)
14483 (copy_intervals_to_string): No longer inline.
14484 * xdisp.c (window_text_bottom_y, window_box_width)

14541 * xmenu.c (cleanup_widget_value_tree): New function.
14542 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
14543 calling free_menubar_widget_value_tree directly (Bug#9830).

14549 (window_box_width, window_box_left, window_box_left_offset)
14550 (window_box_right, window_box_right_offset): Declare extern.
14551 Otherwise, these inline functions do not conform to C99 and
14552 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14553 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14554 * intervals.c (adjust_intervals_for_insertion)

14557 (static_offset_intervals): Remove.
14558 (offset_intervals): Rewrite using the old contents of
14559 static_offset_intervals. The old version didn't conform to C99
14560 because an extern inline function contained a reference to an
14561 identifier with static linkage.

14613 * nsfns.m: Declare image_cache_refcount if GLYPH_DEBUG.
14614 (unwind_create_frame): New function (Bug#9943).
14615 (Fx_create_frame): Restructure code to be more similar to the one in
14616 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).

14656 (fstat, stat, utime) [_MSC_VER]: Redirect to their sys_* cousins.
14657 (malloc, free, realloc, calloc) [_MSC_VER]: Always redirect to the
14659 (alloca) [_MSC_VER]: Define to _alloca.
14661 * lisp.h (DECL_ALIGN) [_MSC_VER]: Define for MSVC.
14663 * regex.c <re_char> [_MSC_VER]: A separate definition for MSVC.
14665 2011-11-04 Eli Zaretskii <eliz@gnu.org>
14667 * xdisp.c (note_mouse_highlight): If either of
14668 previous/next-single-property-change returns nil, treat that as
14669 the beginning or the end of the buffer. (Bug#9955)
14671 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
14673 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
14674 label is not null (Bug#9951).
14675 (xg_tool_item_stale_p): Handle the fact that wimage and/or wlbl
14678 2011-11-04 Eli Zaretskii <eliz@gnu.org>
14680 * window.c (Fwindow_body_size): Mention in the doc string that the
14681 return value is in frame's canonical units. (Bug#9949)
14683 2011-11-03 Eli Zaretskii <eliz@gnu.org>
14685 * xdisp.c (note_mouse_highlight): Initialize `area'. (Bug#9947)
14687 * w32fns.c (unwind_create_frame): If needed, free the glyph
14688 matrices of the partially constructed frame. (Bug#9943)
14689 * xfns.c (unwind_create_frame): Likewise.
14691 2011-11-01 Eli Zaretskii <eliz@gnu.org>
14693 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
14694 Don't stop backward scan on the continuation glyph, even though
14695 its CHARPOS is positive.
14696 (mouse_face_from_buffer_pos, note_mouse_highlight):
14697 Rename cover_string to disp_string.
14699 2011-11-01 Martin Rudalics <rudalics@gmx.at>
14701 * window.c (temp_output_buffer_show): Don't use
14702 Vtemp_buffer_show_specifiers.
14703 (Vtemp_buffer_show_specifiers): Remove unused variable.
14705 2011-10-30 Eli Zaretskii <eliz@gnu.org>
14707 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
14708 past the beginning of the current glyph matrix.
14710 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
14712 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
14713 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
14714 HAVE_GTK3 (Bug#9869).
14716 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
14717 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
14719 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
14721 * xterm.c: Declare x_handle_net_wm_state to return int.
14722 (handle_one_xevent): Check if we are iconified but don't have
14723 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
14724 (get_current_wm_state): Return non-zero if not hidden,
14725 check for _NET_WM_STATE_HIDDEN (Bug#9893).

14730 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
14732 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
14733 so that this new function doesn't get optimized away by a
14734 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
14736 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
14738 * frame.h (MOUSE_HL_INFO): Remove excess parens.
14740 2011-10-29 Eli Zaretskii <eliz@gnu.org>
14742 Fix the `xbytecode' command.
14743 * .gdbinit (xprintbytestr): New command.
14744 (xwhichsymbols): Rename from `which'; all callers changed.
14745 (xbytecode): Print the byte-code string as well.
14747 2011-10-29 Kim Storm <storm@cua.dk>
14749 * alloc.c (which_symbols): New function.
14751 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
14753 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
14756 2011-10-29 Glenn Morris <rgm@gnu.org>
14758 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
14759 Not clear what it was for, and it causes various bugs. (Bug#9839)
14761 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14763 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
14764 possible random value that matches one of those tested as
14765 condition to clear the mouse face.
14767 2011-10-28 Chong Yidong <cyd@gnu.org>
14769 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
14771 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
14773 * window.c (make_window): Initialize phys_cursor_on_p.
14775 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
14777 * lisp.h (struct Lisp_Symbol): Update comments.
14779 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
14781 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
14783 2011-10-28 Eli Zaretskii <eliz@gnu.org>
14785 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
14786 <oslsachem@gmail.com> for helping to debug this.
14788 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
14789 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
14790 (g_b_init_get_glyph_outline_w): New static variables.
14791 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
14792 (GetGlyphOutlineW_Proc): New typedefs.
14793 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
14794 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
14796 (w32font_open_internal, compute_metrics):
14797 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14798 instead of calling the "wide" APIs directly.
14800 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
14802 * w32.h (syms_of_w32font): Add prototype.
14804 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14806 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
14807 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
14808 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
14809 (Fmove_to_window_line): Doc fix.
14811 2011-10-27 Chong Yidong <cyd@gnu.org>
14813 * process.c (make_process): Set gnutls_state to NULL.
14815 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14816 non-NULL, regardless of GNUTLS_INITSTAGE.
14817 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
14818 an error. Set process slots as soon as we allocate them.
14820 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
14822 2011-10-27 Chong Yidong <cyd@gnu.org>
14824 * gnutls.c (emacs_gnutls_deinit): New function.
14825 Deallocate credentials structures as well as calling gnutls_deinit.
14826 (Fgnutls_deinit, Fgnutls_boot): Use it.
14828 * process.c (make_process): Initialize GnuTLS credentials to NULL.
14829 (deactivate_process): Call emacs_gnutls_deinit.
14831 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
14833 * image.c (x_create_x_image_and_pixmap):
14834 * w32.c (sys_rename, w32_delayed_load):
14835 * w32font.c (fill_in_logfont):
14836 * w32reg.c (x_get_string_resource): Silence compiler warnings.
14838 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
14840 * w32fns.c (w32_default_color_map): New function,
14841 extracted from Fw32_default_color_map.
14842 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
14844 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14846 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
14848 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
14850 * keyboard.c (test_undefined): New function (bug#9751).
14851 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
14853 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
14855 * sysdep.c (init_sys_modes): Fix the check for the controlling
14856 terminal (Bug#6649).
14858 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14860 * dispextern.h (struct bidi_it): New member next_en_type.
14862 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14863 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14864 current character, check also for next_en_type being WEAK_EN.
14865 (bidi_resolve_weak): Don't enter the expensive loop if the current
14866 position is before next_en_pos. Record the bidi type of the first
14867 non-ET, non-BN character we find, in addition to its position.
14868 (bidi_level_of_next_char): Invalidate next_en_type when
14869 next_en_pos is over-stepped.
14871 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14873 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14874 * editfns.c: Rewrite current-time-zone so that it invokes
14875 the equivalent of (format-time-string "%Z") to get the time zone name.
14876 This fixes a bug when the time zone name contains characters that
14877 need converting from the system time locale to Emacs internal format.
14878 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14879 that patch fixed format-time-string to do the conversion, but
14880 I forgot to fix current-time-zone.
14881 (format_time_string): New function, containing most of
14882 what Fformat_time_string used to contain.
14883 (Fformat_time_string): Rewrite in terms of format_time_string.
14884 This doesn't change this function's behavior.
14885 (current-time-zone): Rewrite to use format_time_string.
14886 This fixes the bug reported by Michael Schierl in
14887 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14888 Jason Rumney's 2007-06-07 change worked around this bug, but
14890 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14892 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14894 * xdisp.c (start_display): If the character at POS is displayed
14895 via a display vector, reset IT->current.dpvec_index to zero.
14896 (try_window_reusing_current_matrix): If a line ends in a display
14897 vector or the next line starts in a display vector, continue
14898 redrawing the window even though the character position of
14899 start_row was reached.
14902 2011-10-18 Chong Yidong <cyd@gnu.org>
14904 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14905 with nobreak-char-display too.
14907 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14909 Fix part 3 of bug#9771.
14910 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14911 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14912 non-neutral characters if the current character is a paragraph
14913 separator (a.k.a. Newline). This avoids running the same
14914 expensive loop twice, once when we consume the preceding newline
14915 and the other time when the line actually needs to be displayed.
14916 Avoid the loop when we see neutrals on the base embedding level
14917 following a character whose directionality is the same as the
14918 paragraph's. This avoids running the expensive loop when a line
14919 ends in a long sequence of neutrals, like control characters.
14920 Add assertion against STRONG_AL type. Slightly rearrange code
14921 that determines the type of a neutral given the first non-neutral
14923 (bidi_level_of_next_char): Set next_en_pos to zero when
14924 invalidating its info.
14926 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14928 * xdisp.c (push_display_prop): Determine whether to record string
14929 or buffer position by IT->string, not by IT->method. Allow
14930 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14931 (move_it_vertically_backward): Don't look for character position
14932 immediately after the newline when in a continuation line.
14935 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14937 * window.c (coordinates_in_window): Rewrite and delabelize
14938 vertical border check. (Bug#5357) (Bug#9618)
14940 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14942 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14943 errors in XSetWindowBorder (bug#9310).
14945 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14947 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14948 avoid crash when xmalloc overrun checking is enabled.
14950 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14952 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14953 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14954 cursor motion with <left> and <right> arrow keys.
14956 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14957 some callers set that themselves.
14959 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14961 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14962 display string and the previous row comes from the same string and
14963 is empty. (Bug#9739) (Bug#9738)
14965 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14967 * doc.c (get_doc_string): Encode file name (bug#9735).
14969 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14971 * bidi.c (bidi_level_of_next_char):
14972 * xdisp.c (get_visually_first_element): Remove old incorrect
14973 comments regarding the Unicode Line Separator character.
14975 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14977 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14979 * alloc.c (Fgc_status): Do not access beyond zombies array
14980 boundary if nzombies > MAX_ZOMBIES.
14981 * alloc.c (dump_zombies): Add missing format specifier.
14983 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14985 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14986 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14988 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14989 Some packages use them to denote characters with modifiers.
14991 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14993 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14994 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14995 matching a pp-number. Rename parameter var to var1.
14997 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14999 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15001 2011-10-08 Glenn Morris <rgm@gnu.org>
15003 * callint.c (Fcall_interactively): Give a more explicit error for the
15004 'c' case with a non-character input. (Bug#8479)
15006 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15008 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15010 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15011 lines that are hscrolled on the left.
15013 * dispnew.c (buffer_posn_from_coords): Account for a possible
15014 presence of header-line. (Bug#4426)
15016 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15018 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15019 Don't advertise functionality which we discourage or doesn't work.
15021 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15023 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15024 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15025 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15026 this makes Emacs dump core during garbage collection on rare
15027 occasions. sizeof is obviously inferior to offsetof here, so
15028 stick with offsetof.
15029 (GC_POINTER_ALIGNMENT): New macro.
15030 (mark_memory): Omit 3rd (offset) arg; caller changed.
15031 Don't assume EMACS_INT alignment is the same as pointer alignment.
15033 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15035 * keyboard.c (read_key_sequence_remapped): New var.
15036 (read_key_sequence): Compute remapping in the right buffer.
15037 (command_loop_1): Use read_key_sequence's remapping directly.
15039 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15041 * dired.c (file_name_completion): Don't expand file name.
15042 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15043 before checking file name handler.
15045 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15046 they've been requested explicitly (bug#9591).
15048 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15050 * keymap.c (Fsingle_key_description): Use make_specified_string
15051 instead of build_string to build string from push_key_description.
15054 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15056 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15057 This fixes a Y2038 bug on 64-bit hosts.
15058 * buffer.c (reset_buffer):
15059 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15060 (Fclear_buffer_auto_save_failure):
15061 Use 0, not -1, to represent an unset failure time, since time_t
15062 might not be signed.
15064 Remove dependency on glibc malloc internals.
15065 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15066 Move back here from lisp.h, but with their new implementations.
15067 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15068 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15069 * charset.c (charset_table_init): New static var.
15070 (syms_of_charset): Use it instead of xmalloc. This removes a
15071 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15072 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15073 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15074 Move back to alloc.c.
15075 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15076 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15078 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15080 * nsterm.m (windowDidResize): Call x_set_window_size only when
15081 ns_in_resize is true. Otherwise set pixelwidth/height and
15082 call change_frame_size (Bug#9628).
15084 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15086 Port --enable-checking=all to Fedora 14 x86-64.
15087 * charset.c (syms_of_charset): Also account for glibc malloc's
15088 internal overhead when calculating the initial malloc maximum.
15090 Port --enable-checking=all to Fedora 14 x86.
15091 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15093 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15094 (overrun_check_realloc, overrun_check_free):
15095 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15096 That way, xmalloc returns a properly-aligned pointer even if
15097 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15098 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15099 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15100 into account when calculating the initial malloc maximum.
15101 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15102 Move here from alloc.c, so that charset.c can use it too.
15103 Properly align; the old code wasn't right for common 32-bit hosts
15104 when configured with --enable-checking=all.
15105 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15106 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15108 2011-09-29 Eli Zaretskii <eliz@gnu.org>

15115 * xdisp.c (compute_display_string_end): If there's no display
15116 string at CHARPOS, return -1.
15118 * bidi.c (bidi_fetch_char): When compute_display_string_end
15119 returns a negative value, treat the character as a normal
15120 character not covered by a display string. (Bug#9624)
15122 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15124 * lread.c (Fread_from_string): Fix typo in docstring.
15126 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15128 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15129 newline, reseat the iterator instead of bidi-iterating there one
15130 character at a time. (Bug#9610)
15131 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15132 TO_CHARPOS if the bidi iterator is at base embedding level.

15136 * lread.c (readevalloop): Use correct code for NBSP.
15137 (read1): Likewise. (Bug#9608)
15139 2011-09-25 Michael Albinus <michael.albinus@gmx.de>

15144 2011-09-25 Glenn Morris <rgm@gnu.org>
15146 * buffer.c (truncate-lines): Doc fix.

15166 Default value is now t. Doc fix.
15168 * indent.c (Fvertical_motion): Compute and apply the overshoot
15169 logic when moving up, not only when moving down. Fix the
15170 confusing name and values of the it_overshoot_expected variable;
15171 logic changes accordingly. (Bug#9254) (Bug#9549)
15173 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15174 CHARPOS is covered by a display string which includes newlines.
15175 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15176 is covered by a display string with embedded newlines.
15178 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15180 * dbusbind.c (Fdbus_register_signal): Add match rule to

15182 (Fdbus_register_method, Vdbus_registered_objects_table):
15185 2011-09-24 Jim Meyering <meyering@redhat.com>
15187 do not ignore write error for any output size
15188 The previous change was incomplete.
15189 While it makes emacs --batch detect the vast majority of stdout
15190 write failures, errors were still ignored whenever the output size is
15191 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15192 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15193 && echo FAIL: ignored write error
15194 FAIL: ignored write error
15195 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15196 && echo FAIL: ignored write error
15197 FAIL: ignored write error
15198 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15200 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15202 * emacs.c (Fkill_emacs): In noninteractive mode exit
15203 non-successfully if a write error occurred on stdout. (Bug#9574)
15205 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15207 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15210 * dispextern.h (struct it): Update the comment documenting what
15213 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15215 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15216 a display string, extend search for cursor position to end of row.
15217 (find_row_edges): If the row ends in a newline from a display
15218 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15219 Handle the case of a display string with multiple newlines.
15220 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15221 non-empty line. Fixes confusing cursor motion with arrow keys at
15222 the beginning of a line that starts with whitespace.
15224 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15226 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15229 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15231 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15232 boolean (Bug#9154).
15234 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15236 * xdisp.c (display_line): Record maximum and minimum buffer
15237 positions even if no glyphs were produced (e.g., by a zero-width
15238 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15239 buffer positions that will be removed from the glyph row because
15241 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15242 column is beyond frame width: don't subtract 1 "pixel" when
15243 computing width of the stretch.
15244 (reseat_at_next_visible_line_start): Undo the change made on
15245 2011-09-17 that saved paragraph information and restored it after
15246 the call to `reseat'. (Bug#9545)
15248 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15250 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15251 and turn window cursor on if cleared (Bug#9415).
15253 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15255 * search.c (boyer_moore): Take unibyte characters from pattern
15256 literally. (Bug#9458)

15266 initialized, to pacify gcc -Wuninitialized.
15268 * fileio.c: Report proper errno when syscall falls.
15269 (Finsert_file_contents): Save and restore errno,
15270 so that report_file_error outputs the correct diagnostic.
15271 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15273 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15275 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15277 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15279 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15280 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
15282 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15284 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15285 about the current paragraph and restore it after the call to reseat.
15287 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15288 (bidi_find_paragraph_start): Search back for paragraph beginning
15289 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15290 (bidi_move_to_visually_next): Only trigger paragraph-related
15291 computations when the last character is a newline or at EOB, not
15292 just any NEUTRAL_B. (Bug#9470)
15294 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15295 truncated lines if point is covered by a display string. (Bug#9524)
15297 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15299 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15300 (cons_to_x_long): New function.
15301 (lisp_data_to_selection_data): Use it. Correct the test for
15302 short-versus-long data; it was negated. Break out of vector
15303 loop, for efficiency, when a long datum is discovered.
15305 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15307 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15309 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15311 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
15312 GCC PR/17406) by declaring this function with external scope.
15314 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15316 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
15317 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
15319 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
15321 * editfns.c (Fformat): Correctly handle text properties on "%%".

15330 (fill_composite_glyph_string): Add comments about special meaning
15331 of TAB characters in a composition.
15333 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15335 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15336 This occurs when processing a multibyte format.
15337 Problem reported by Wolfgang Jenker.
15339 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15341 * xdisp.c (try_cursor_movement): Only check for exact match if
15342 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15344 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15346 Remove unused external symbols.
15347 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15348 * xdisp.c (calc_pixel_width_or_height): Now static.
15349 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
15350 * indent.c (check_display_width):
15351 * w32term.c: Fix comment to match code.
15352 * xterm.c, xterm.h (x_catching_errors): Remove.
15354 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15356 * xselect.c: Use signed conversions more consistently (Bug#9498).
15357 (selection_data_to_lisp_data): Assume incoming selection data are
15358 signed integers, not unsigned. This is to be consistent with
15359 outgoing selection data, which was modified to use signed integers
15360 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15361 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15362 expects long, not unsigned long.
15364 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15366 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15367 computation of loop end. Reported by Johan Bockgård
15370 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15372 * frame.c (Fother_visible_frames_p): Function deleted.
15374 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15376 * indent.c (compute_motion): Process display vector front to back
15377 rather than the other way around. (Bug#2496)
15379 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15381 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15383 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15385 * minibuf.c (Fread_from_minibuffer): Doc fix.
15387 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15389 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15390 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15392 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15394 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15395 value for non-existent files.
15397 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15399 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15400 set its "size" to -1. This will set the modtime_size field of
15401 the corresponding buffer to -1, which is what
15402 verify-visited-file-modtime expects for files that do not exist.
15405 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15407 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15409 * lisp.h: ... from here. push_key_description is no longer
15410 defined in keyboard.c, so its declaration should not be in
15411 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15412 logically belongs with push_key_description.
15414 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15416 * buffer.h: Include <sys/types.h> instead of <time.h>.
15417 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15418 Problem reported by Herbert J. Skuhra.
15420 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15422 * xml.c (parse_region): Make the parsing work for
15423 non-comment-starting XML files again (bug#9144).
15425 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15427 * image.c (gif_load): Fix calculation of bottom and right corner.
15430 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15432 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15433 redisplay in small windows.
15435 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15437 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15439 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15441 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15442 Operate on live windows only.
15444 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15446 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15448 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15450 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15451 only under bidi iteration.
15453 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15455 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15457 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15459 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15460 Without this fix, the command to link temacs failed due to an
15461 undefined symbol __builtin_isnan. This is because
15462 /usr/include/iso/math_c99.h #defines isnan(x) to
15463 __builtin_isnan(x), but the bundled gcc, which identifies itself
15464 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15466 * floatfns.c (isnan): #undef, and then #define to a clone of
15468 (Fisnan): Always define, since it's always available now.
15469 (syms_of_floatfns): Always define isnan at the Lisp level.
15471 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15473 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15475 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15477 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15478 The previous code assumed that file offsets (off_t values) fit in
15479 EMACS_INT variables, which is not true on typical 32-bit hosts.
15480 The code messed up by falsely reporting buffer overflow in cases
15481 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15482 when "big" contains more than 2**29 bytes, even though this
15483 inserts just one byte and does not overflow the buffer.
15484 (Finsert_file_contents): Store file offsets as off_t
15485 values, not as EMACS_INT values. Check for overflow when
15486 converting between EMACS_INT and off_t. When checking for
15487 buffer overflow or for overlap, take the offsets into account.
15488 Don't use EMACS_INT for small values where int suffices.
15489 When checking for overlap, fix a typo: ZV was used where
15490 ZV_BYTE was intended.
15491 (Fwrite_region): Don't assume off_t fits into 'long'.
15492 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15494 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15496 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15498 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15500 sprintf-related integer and memory overflow issues (Bug#9412).
15502 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15503 (esprintf, exprintf, evxprintf): New functions.
15504 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15505 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15506 (modify_event_symbol): Do not assume that the length of
15507 name_alist_or_stem is safe to alloca and fits in int.
15508 (Fexecute_extended_command): Likewise for function name and binding.
15509 (Frecursion_depth): Wrap around reliably on integer overflow.
15510 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15511 since some callers pass EMACS_INT values.
15512 (Fsingle_key_description): Don't crash if symbol name contains more
15513 than MAX_ALLOCA bytes.
15514 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15515 (get_minibuffer): Arg is now EMACS_INT, not int.
15516 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15517 (esprintf, exprintf, evxprintf): New decls.
15518 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15520 * dbusbind.c (signature_cat): New function.
15521 (xd_signature, Fdbus_register_signal):
15522 Do not overrun buffer; instead, report string overflow.
15524 * dispnew.c (add_window_display_history): Don't overrun buffer.
15525 Truncate instead; this is OK since it's just a log.
15527 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15528 even if the time zone offset is outlandishly large.
15529 Don't mishandle offset == INT_MIN.
15531 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15532 when creating daemon; the previous buffer-overflow check was incorrect.
15534 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15535 which has the guts of the old verror function.
15537 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15538 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15540 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15541 (font_unparse_xlfd): Don't blindly alloca long strings.
15542 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15543 fits in int, when using sprintf. Use single snprintf to count
15544 length of string rather than counting it via multiple sprintfs;
15545 that's simpler and more reliable.
15546 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15547 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15548 sprintf, in case result does not fit in int.
15550 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15551 (fontset_from_font): Print it.
15553 * frame.c (tty_frame_count): Now printmax_t, not int.
15554 (make_terminal_frame, set_term_frame_name): Print it.
15555 (x_report_frame_params): In X, window IDs are unsigned long,
15556 not signed long, so print them as unsigned.
15557 (validate_x_resource_name): Check for implausibly long names,
15558 and don't assume name length fits in 'int'.
15559 (x_get_resource_string): Don't blindly alloca invocation name;
15560 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15563 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15564 (xg_check_special_colors, xg_set_geometry):
15565 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15567 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15568 Use esprintf, not sprintf, in case result does not fit in int.
15570 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15571 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15572 it as a large positive number.
15573 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15574 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15576 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15577 in case result does not fit in int.
15579 * print.c (float_to_string): Detect width overflow more reliably.
15580 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15581 buffer overrun. Don't assume list length fits in 'int'. Treat
15582 print length of 0 as 0, not as infinity; to be consistent with other
15583 uses of print length in this function. Don't overflow print length
15584 index. Don't assume hash table size fits in 'long', or that
15585 vectorlike size fits in 'unsigned long'.
15587 * process.c (make_process): Use printmax_t, not int, to format
15588 process-name gensyms.
15590 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15592 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15593 to avoid potential buffer overrun.
15595 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15596 if X resource line is longer than 512 bytes.
15598 * xfns.c (x_window): Make sprintf buffer a bit bigger
15599 to avoid potential buffer overrun.
15601 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15603 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15605 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15607 Integer overflow fixes for scrolling, etc.
15608 Without these, Emacs silently mishandles large integers sometimes.
15609 For example, "C-u 4294967297 M-x recenter" was treated as if
15610 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15612 * xdisp.c (try_window_id): Check Emacs fixnum range before
15613 converting to 'int'.
15615 * window.c (window_scroll_line_based, Frecenter):
15616 Check that an Emacs fixnum is in range before assigning it to 'int'.
15617 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15618 values converted from Emacs fixnums.
15619 (Frecenter): Don't wrap around a line count if it is out of 'int'
15620 range; instead, treat it as an extreme value.
15621 (Fset_window_configuration, compare_window_configurations):
15622 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15624 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15625 that can exceed INT_MAX. Check that EMACS_INT value is in range
15626 before assigning it to the (possibly-narrower) index.
15627 (match_limit): Don't assume that a fixnum can fit in 'int'.
15629 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15632 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15633 (Fvertical_motion): Don't wrap around LINES values that don't fit
15634 in 'int'. Instead, treat them as extreme values. This is good
15635 enough for windows, which can't have more than INT_MAX lines anyway.
15637 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15639 * Require libxml/parser.h to avoid compilation warning.
15641 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15643 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15644 since this reportedly can destroy thread storage.
15646 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15648 * syntax.c (find_defun_start): Update all cache variables if
15649 exiting early (Bug#9401).
15651 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15653 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15655 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15656 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15657 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15659 * term.c (tty_append_glyph): New function.
15660 (produce_stretch_glyph): Static function and its prototype deleted.
15662 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15665 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15667 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15668 when checking :margin (Bug#9390).
15669 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15670 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15671 so that the name doesn't mislead. All uses changed.
15673 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15675 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15678 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15680 * xdisp.c (move_it_to): Don't bail out early when reaching
15681 position beyond to_charpos, if we are scanning backwards.
15682 (move_it_vertically_backward): When DY == 0, make sure we get to
15683 the first character in the line after the newline.
15685 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15687 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15688 (ccl_driver): Do not generate an out-of-range pointer.
15689 (Fccl_execute_on_string): Remove unnecessary check for
15690 integer overflow, noted by Stefan Monnier in
15691 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15692 Remove a FIXME that didn't need fixing.
15693 Simplify the newly-introduced buffer reallocation code.
15695 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15697 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15699 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15701 Integer and memory overflow issues (Bug#9196).
15703 * doc.c (get_doc_string): Rework so that
15704 get_doc_string_buffer_size is the actual buffer size, rather than
15705 being 1 less than the actual buffer size; this makes xpalloc more
15708 * image.c (x_allocate_bitmap_record, cache_image):
15709 * xselect.c (Fx_register_dnd_atom):
15710 Simplify previous changes by using xpalloc.
15712 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15713 since either will do and ptrdiff_t is convenient with xpalloc.
15715 * charset.c (charset_table_size)
15716 (struct charset_sort_data.priority): Now ptrdiff_t.
15717 (charset_compare): Don't overflow if priorities differ greatly.
15718 (Fsort_charsets): Don't assume list length fits in int.
15719 Check for size-calculation overflow when allocating sort data.
15720 (syms_of_charset): Allocate an initial charset table that is
15721 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15723 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15725 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15726 The actual value is always <= INT_MAX, and leaving it unsigned made
15727 overflow checking harder.
15729 * dispextern.h (struct glyph_matrix.rows_allocated)
15730 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15731 with xpalloc. The values are still always <= INT_MAX.
15733 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15735 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15736 (SAFE_NALLOCA): New macro.
15738 * region-cache.c (struct boundary.pos, find_cache_boundary)
15739 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15740 (set_cache_region, invalidate_region_cache)
15741 (revalidate_region_cache, know_region_cache, region_cache_forward)
15742 (region_cache_backward, pp_cache):
15743 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15744 so that ptrdiff_t * can be passed to xpalloc.
15745 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15746 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15747 (pp_cache): Don't assume cache_len fits in int.
15748 * region-cache.h: Adjust extern decls to match.
15750 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15751 EMACS_INT, since either will do, for xpalloc.
15753 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15754 (xnmalloc, xnrealloc, xpalloc): New functions.
15756 * bidi.c (bidi_shelve_header_size): New constant.
15757 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15758 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15760 * bidi.c (bidi_cache_shrink):
15761 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15763 Don't update size of array until after memory allocation succeeds,
15764 because xmalloc/xrealloc may not return.
15765 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15766 now that we have proper integer overflow checking.
15767 (record_overlay_string, overlay_strings): Catch overflows when
15768 calculating size of overlay_str_buf.
15770 * callproc.c (Fcall_process): Check for size overflow when
15771 calculating size of args2.
15772 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15773 Normally we prefer signed values, but sticking with ptrdiff_t would
15774 require adding more-complicated checks.
15776 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15777 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15778 Redo buffer-overflow calculations to avoid integer overflow.
15779 Add a FIXME comment where memory seems to be over-allocated.
15781 * character.c (Fstring): Check for size-calculation overflow.
15783 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15784 unnecessary integer overflow. Check for size overflow.
15785 (encode_coding_object): Don't update size until xmalloc succeeds.
15787 * composite.c (get_composition_id): Check for overflow in glyph
15788 length calculations.
15790 Integer and memory overflow fixes for display code.
15791 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15792 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15793 (scrolling_window): Check for overflow in size calculations.
15794 (line_draw_cost, realloc_glyph_pool, add_row_entry):
15795 Don't assume glyph table len fits in int.

15797 (row_table_size): Now ptrdiff_t, not int.
15798 (scrolling_window): Avoid overflow in size calculations.
15799 Don't update size until allocation succeeds.
15800 * fns.c (concat): Check for overflow in size calculations.
15801 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15802 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

15805 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15806 (get_doc_string): Check for size calculation overflow.
15807 Don't update size until allocation succeeds.
15808 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15809 EMACS_INT, where ptrdiff_t will do.
15810 (Fsubstitute_command_keys): Check for string overflow.
15812 * editfns.c (set_time_zone_rule): Don't assume environment length
15814 (message_length): Now ptrdiff_t, not int.
15815 (Fmessage_box): Don't update size until allocation succeeds.
15816 Don't assume message length fits in int.
15817 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15819 * emacs.c (main): Do not reallocate argv, since there is a null at
15820 the end that can be overwritten, and this way there's no need to
15821 worry about size-calculation overflow.
15822 (sort_args): Check for size-calculation overflow.
15824 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15826 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15828 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15829 (x_set_scroll_bar_width, x_figure_window_size):
15830 Check for integer overflow.
15831 (x_set_alpha): Do not assume XINT fits in int.
15833 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15834 This is for the members text_lines, text_cols, total_lines, total_cols,
15835 where the system imposes an 'int' limit.
15837 * fringe.c (Fdefine_fringe_bitmap):
15838 Don't update size until alloc works.
15840 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15841 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15843 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15844 Check for size-calculation overflow.
15845 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15846 do, as we prefer signed integers.
15847 (id_to_widget.max_size, id_to_widget.used)
15848 (xg_store_widget_in_map, xg_remove_widget_from_map)
15849 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15850 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15851 Use and return ptrdiff_t, not int.
15852 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15853 * gtkutil.h: Change prototypes to match the above.
15855 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15856 are duplicate now that they've been promoted to lisp.h.
15857 (x_allocate_bitmap_record, x_alloc_image_color)
15858 (make_image_cache, cache_image, xpm_load):
15859 Don't update size until alloc is done.
15860 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
15862 Check for size calculation overflow.
15863 (ct_colors_allocated_max): New constant.
15864 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
15867 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
15868 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
15869 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15870 Use ptrdiff_t, not int, to count maps.
15871 (read_char_minibuf_menu_prompt): Check for overflow in size
15872 calculations. Don't update size until allocation succeeds.
15873 Redo calculations to avoid overflow.
15874 * keyboard.h: Change prototypes to match the above.
15876 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15878 (current_minor_maps): Check for size calculation overflow.
15879 * keymap.h: Change prototypes to match the above.
15881 * lread.c (read1, init_obarray): Don't update size until alloc done.
15883 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
15884 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
15886 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
15887 Now ptrdiff_t, not int.
15888 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

15894 * region-cache.c (move_cache_gap): Check for size calculation overflow.
15896 * scroll.c (do_line_insertion_deletion_costs): Check for size calc

15900 (Fset_match_data): Don't assume list lengths fit in 'int'.
15902 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15903 for command line length. Do not attempt to address one before the
15904 beginning of an array, as that's not portable.
15906 * term.c (max_frame_lines): Remove; unused.
15907 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
15909 (encode_terminal_code, calculate_costs): Check for size
15910 calculation overflow.
15911 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
15912 table lengths and related sizes. Don't update size until alloc
15913 done. Redo calculations to avoid overflow.
15914 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
15916 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
15917 subtracting pointers.
15918 (gobble_line): Check for overflow more carefully. Don't update size
15921 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
15922 Don't update size until alloc done.

15928 Use ptrdiff_t, not int, for sizes.
15929 (store_mode_line_noprop_char): Don't update size until alloc done.

15932 Use ptrdiff_t, not int, for sizes.
15933 (Finternal_make_lisp_face, cache_face):
15934 Check for size calculation overflow.
15935 (cache_face): Treat size calculation overflows as if they were
15936 memory exhaustion (the usual treatment), rather than aborting.
15938 * xfns.c (x_encode_text, x_set_name_internal)
15939 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15940 sizes, since they can exceed INT_MAX in size. Check for size
15941 calculation overflow.
15943 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
15944 (xg_select): Check for size calculation overflow.
15945 Don't update size until alloc done.
15947 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15948 as sprintf is limited to int lengths.
15950 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15951 (X_LONG_MIN): New macros.
15952 Use them to make the following changes clearer.
15953 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15954 This change doesn't affect the value now, but it may help remind
15955 future maintainers not to raise the value too much later.
15956 (SELECTION_QUANTUM): Remove, replacing with ...
15957 (selection_quantum): ... new function, which avoids overflow.
15959 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15960 assumption that selection length fits in 'int'.
15961 (x_reply_selection_request, x_handle_selection_request)
15962 (x_get_window_property, receive_incremental_selection)
15963 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
15964 (lisp_data_to_selection_data, clean_local_selection_data):
15965 Use ptrdiff_t, not int, to record length of selection.
15966 (x_reply_selection_request, x_get_window_property)
15967 (receive_incremental_selection, x_property_data_to_lisp):
15968 Redo calculations to avoid overflow.
15969 (x_reply_selection_request): When sending hint, ceiling it at
15970 X_LONG_MAX rather than relying on wraparound overflow to send
15972 (x_get_window_property, receive_incremental_selection)
15973 (lisp_data_to_selection_data, x_property_data_to_lisp):
15974 Check for size-calculation overflow.
15975 (x_get_window_property, receive_incremental_selection)
15976 (lisp_data_to_selection_data, Fx_register_dnd_atom):
15977 Don't store size until memory allocation succeeds.
15978 (x_get_window_property): Plug memory leak on memory exhaustion.
15979 Don't double-block input; malloc is safe here. Don't assume 2**34
15980 - 4 fits in unsigned long. Add an xassert to check
15981 XGetWindowProperty overflow. Be more careful about overflow
15982 calculations, and distinguish size from memory overflow better.
15983 (receive_incremental_selection): When tracing, don't assume
15984 unsigned int is less than INT_MAX.
15985 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15986 harmful) conversions of unsigned short to int.
15987 (lisp_data_to_selection_data): Don't assume that integers
15988 in the range -65535 through -1 fit in an X unsigned short.
15989 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15990 result parameters unless successful. Rely on cons_to_unsigned
15991 to report problems with elements; the old code wasn't right anyway.
15992 (x_check_property_data): Check for int overflow; we cannot use
15993 a wider type due to X limits.
15994 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
15996 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
15998 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
15999 (x_term_init): Check for size calculation overflow.
16000 (x_color_cells): Don't store size until memory allocation succeeds.
16001 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
16002 Don't assume alloca size is less than MAX_ALLOCA.

16026 * lisp.h (hash_lookup, hash_put):
16027 * minibuf.c (Ftest_completion):
16028 Use ptrdiff_t for hash table indexes, not int (which is too
16029 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16030 32-bit --with-wide-int hosts).
16032 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16033 Add a FIXME comment about memory leaks.
16034 (syms_of_charset): Don't assume xmalloc returns.

16038 * character.h (CHAR_WIDTH):
16039 * indent.c (MULTIBYTE_BYTES_WIDTH):
16040 Use sanitize_char_width to avoid undefined and/or bad behavior
16041 with outlandish widths.
16042 * character.h (sanitize_tab_width): Rename from sanitize_width,
16043 now that we have two such functions. All uses changed.

16061 * xterm.c: Don't go over XClientMessageEvent limit.
16062 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16063 (x_send_scroll_bar_event): Likewise. Check that the size does not
16064 exceed limits imposed by XClientMessageEvent, as well as the usual
16065 ptrdiff_t and size_t limits.
16067 * keyboard.c: Overflow, signedness and related fixes.
16068 (make_lispy_movement): Use same integer type in forward decl
16069 that is used in the definition.
16070 (read_key_sequence, keyremap_step):
16071 Change bufsize argument back to int, undoing my 2011-03-30 change.
16072 We prefer signed types, and int is wide enough here.
16073 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16074 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16075 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16076 length, not size_t. Use ptrdiff_t for index, not int.
16077 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16078 possibility of integer overflow.
16080 Overflow, signedness and related fixes for images.

16102 (lookup_image): Remove unnecessary tests.
16103 (xbm_image_p): Locals are now of int, not EMACS_INT,
16104 since parse_image_check makes sure they fit into int.
16105 (png_load, gif_load, svg_load_image):
16106 Prefer int to unsigned where either will do.
16107 (tiff_handler): New function, combining the cores of the
16108 old tiff_error_handler and tiff_warning_handler.
16109 This function is rewritten to use vsnprintf and thereby avoid
16110 stack buffer overflows. It uses only the features of vsnprintf
16111 that are common to both POSIX and native Microsoft.
16112 (tiff_error_handler, tiff_warning_handler): Use it.
16113 (tiff_load, gif_load, imagemagick_load_image):
16114 Don't assume :index value fits in 'int'.
16115 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16116 (imagemagick_load_image): Check that crop parameters fit into
16117 the integer types that MagickCropImage accepts. Don't assume
16118 Vimagemagick_render_type has a nonnegative value. Don't assume
16119 size_t fits in 'long'.
16120 (gs_load): Use printmax_t to print the widest integers possible.

16133 handle_single_display_spec, not just 1 or zero.
16134 (handle_single_display_spec): If the display spec is of the form
16135 `(space ...)', and specifies display in the text area, return 2
16137 (try_cursor_movement): Check for the need to scroll more
16138 accurately, and prefer exact match for point under bidi.
16139 Don't advance `row' beyond the last row of the window.
16141 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
16142 into disp_prop; all users changed.
16144 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

16156 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
16157 buffers, return left-to-right.
16158 (set_cursor_from_row): Consider candidate row a win if its glyph
16159 represents a newline and point is on that newline. Fixes cursor
16160 positioning on the newline at EOL of R2L text within L2R
16161 paragraph, and vice versa.
16162 (try_cursor_movement): Check continued rows, in addition to
16163 continuation rows. Fixes unwarranted scroll when point enters a
16164 continued line of R2L text within an L2R paragraph, or vice versa.
16165 (cursor_row_p): Consider the case of point being equal to
16166 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
16167 from the end of a short line to the beginning of a continued line
16168 of R2L text within L2R paragraph.
16169 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

16187 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
16188 extra slot even if the purpose is char-code-property-table.
16190 2011-08-23 Eli Zaretskii <eliz@gnu.org>
16192 * xdisp.c (redisplay_window): When computing centering_position,
16193 account for the height of the header line. (Bug#8874)
16195 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16196 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16197 candidate is selected by the mouse, and that candidate has a
16198 composed character under the mouse.
16200 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16201 coordinates reported by pos-visible-in-window-p for a composed
16202 character in column zero.
16204 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
16206 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
16208 2011-08-22 Eli Zaretskii <eliz@gnu.org>
16210 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
16211 consider it a hit if to_charpos is anywhere in the range of the
16212 composed buffer positions.
16214 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16216 * image.c (gif_load): Don't assume that each subimage has the same
16217 dimensions as the base image. Handle disposal method that is
16218 "undefined" by the gif spec (Bug#9335).
16220 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
16222 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
16223 (Fcondition_case): Document `debug' symbol in error handler.
16225 2011-08-19 Eli Zaretskii <eliz@gnu.org>
16227 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
16228 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
16229 from an Org mode buffer to a Speedbar frame.
16231 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
16232 a composition, take its buffer position from IT->cmp_it.charpos.
16233 Fixes cursor positioning at the beginning of a line that begins
16234 with a composed character.
16236 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16238 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16239 character bidirectional type, use STRONG_L instead. Fixes crashes
16240 in a buffer produced by `describe-categories'.
16242 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16243 members before the level stack, so they would be saved and
16244 restored when copying iterator state. Fixes incorrect reordering
16245 around TABs covered by display properties.
16247 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
16249 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

16255 Remove unnecessary aborts (Bug#9081).
16257 2011-08-17 Eli Zaretskii <eliz@gnu.org>
16259 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
16260 has no `load' handler, try opening the file locally. (Bug#9311)
16262 2011-08-16 Ken Brown <kbrown@cornell.edu>
16264 * gmalloc.c: Expand comment.
16266 2011-08-16 Eli Zaretskii <eliz@gnu.org>
16268 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate

16314 * process.c (create_process): Call setup_process_coding_systems
16315 after the pid of the process is set to -1 (Bug#8162).
16317 2011-08-14 Eli Zaretskii <eliz@gnu.org>
16319 * xdisp.c (move_it_in_display_line_to): Don't invoke
16320 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16321 ppos_it. Fixes vertical cursor motion when line beginning is
16322 covered by an image. (Bug#9296)
16324 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
16326 * nsterm.h (ns_run_ascript): Declare.

16330 (ns_run_ascript): New function.
16331 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
16332 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
16333 the event loop. Get status from as_status (Bug#7276).
16335 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16336 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16337 the event loop (Bug#7276).
16339 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

16362 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
16363 (Fnetwork_interface_list): Allocate in increments of bytes instead
16364 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16365 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16367 (struct ifflag_def): notrailers is smart on OSX.
16368 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16369 Get hardware address with getifaddrs if available.
16371 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16373 * xdisp.c (iterate_out_of_display_property): xassert that
16374 IT->position is set to within IT->object's boundaries. Break from
16375 the loop as soon as EOB is reached; avoids infloops in redisplay
16376 when IT->position is set up wrongly due to some bug.
16377 Set IT->current to match the bidi iterator unconditionally.
16378 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16379 entry. Force push_it to save on the stack the current
16380 buffer/string position, to be restored by pop_it. Fix flags in
16381 the iterator structure wrt the object coming from a display
16382 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16383 properties. (Bug#9284)
16385 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16387 * fontset.c (fontset_get_font_group): Add proper type checks.

16400 no-display-properties-and-no-overlays under bidi display.
16401 Set disp_pos in the bidi iterator to avoid searches for display
16402 properties and overlays.
16404 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16406 * editfns.c (Fset_time_zone_rule): Document relationship with the
16409 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
16410 the font entity extracted from the cache (Bug#8109).
16412 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
16414 * composite.c (autocmp_chars): Don't reset point. That is done by
16415 restore_point_unwind (Bug#5984).
16417 2011-08-07 Juri Linkov <juri@jurta.org>
16419 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16420 to show the arg `TIME' instead of `TIMEVAL'.
16422 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16424 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16425 display property strides EOL and includes a newline, as in
16426 longlines-mode. (Bug#9254)
16427 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16428 word-wrap under bidirectional display. (Bug#9224)
16430 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16431 is non-zero, even if the data buffer is NULL. Fixes a crash in
16432 vertical-motion with longlines-mode. (Bug#9254)
16434 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16436 * bidi.c <bidi_cache_total_alloc>: Now static.
16437 (bidi_initialize): Initialize bidi_cache_total_alloc.
16439 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16442 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16443 amount allocated this far in `bidi_cache_total_alloc'.
16444 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16445 non-zero, only free the data buffer without restoring the cache
16446 contents. All callers changed.
16448 * dispextern.h (bidi_unshelve_cache): Update prototype.
16450 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16451 (move_it_in_display_line, move_it_to)
16452 (move_it_vertically_backward, move_it_by_lines): Replace the call
16453 to xfree to an equivalent call to bidi_unshelve_cache.
16454 (move_it_in_display_line_to): Fix logic of returning
16455 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16457 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16459 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16460 came from a string character with a `cursor' property. (Bug#9229)
16462 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16464 * Makefile.in (LIB_PTHREAD): New variable.
16465 (LIBES): Add LIB_PTHREAD (Bug#9216).
16467 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
16468 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
16470 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
16472 * regex.c (re_iswctype): Remove some redundant boolean conversions.
16474 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16476 * xterm.c (x_find_topmost_parent): New function.
16477 (x_set_frame_alpha): Find topmost parent window with
16478 x_find_topmost_parent and set the property there also (bug#9181).
16479 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16481 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16483 * callproc.c (Fcall_process): Avoid vfork clobbering
16484 the local vars buffer, coding_systems, current_dir.
16486 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
16488 * keymap.c (Fmake_composed_keymap): Move to subr.el.
16490 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
16492 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16493 so that it is not optimized away.
16495 * xdisp.c (compute_display_string_pos): Remove unused local.
16497 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16499 Fix slow cursor motion and scrolling in large buffers with
16500 selective display, like Org Mode buffers. (Bug#9218)
16502 * dispextern.h (struct bidi_it): New member disp_prop_p.
16504 * xdisp.c: Remove one-slot cache of display string positions.
16505 (compute_display_string_pos): Accept an additional argument
16506 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16507 for a display string or property. If found, set DISP_PROP_P
16510 * bidi.c (bidi_fetch_char): Accept an additional argument
16511 DISP_PROP_P, and pass it to compute_display_string_pos.
16512 Only handle text covered by a display string if DISP_PROP_P is returned
16513 non-zero. All callers of bidi_fetch_char changed.
16515 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16517 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16519 2010-12-03 Don March <don@ohspite.net>
16521 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16522 last character M-[char] is translated to ESC [char] (bug#7541).
16524 2011-08-02 Kenichi Handa <handa@m17n.org>
16526 * lisp.h (uniprop_table): Extern it.
16528 * chartab.c (uniprop_table): Make it non-static.
16530 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16532 * xdisp.c (forward_to_next_line_start): Accept additional argument
16533 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16535 (reseat_at_next_visible_line_start): Use the bidi iterator state
16536 returned by forward_to_next_line_start to restore the state of
16537 it->bidi_it after backing up to previous newline. (Bug#9212)
16539 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16541 * regex.c (re_comp): Protoize.
16542 (re_exec): Fix return type.
16543 (regexec): Fix type of `ret'. (Bug#9203)
16545 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16547 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16548 This is needed if max-image-size is a floating-point number.
16550 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16552 * print.c (print_object): Print empty symbol as ##.
16554 * lread.c (read1): Read ## as empty symbol.
16556 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16558 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16559 setting frame foreground color (Bug#9175).
16560 (x_set_background_color): Likewise.
16562 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16563 contents (Bug#9176).
16564 (EmacsTooltip -init): Remove bezels and add shadows to
16567 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16568 or scroll bar (Bug#8470).
16570 * nsfont.m (nsfont_open): Remove assignment to voffset and
16571 unnecessary vars hshink, expand, hd, full_height, min_height.
16572 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16574 * nsterm.h (nsfont_info): Remove voffset field.
16576 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16578 Implement strike-through and overline on NextStep (Bug#8863).
16580 * nsfont.m (nsfont_open): Use underline position provided by font,
16581 instead of hard-coded value of 2.
16582 (nsfont_draw): Call ns_draw_text_decoration instead.
16584 * nsterm.h: Add declaration for ns_draw_text_decoration.
16586 * nsterm.m (ns_draw_text_decoration): New function for drawing
16587 underline, overline, and strike-through.
16588 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16589 ns_draw_text_decoration. Change treatment of cursor drawing to
16590 accommodate underlining, etc.
16592 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16594 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16597 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16599 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16600 Without this fix, if a signal arrives just after memory fills up,
16601 'malloc' might be invoked reentrantly.
16603 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16604 In other words, assume that every image size is allowed, on non-X
16605 hosts. This assumption is probably wrong, but it lets Emacs compile.
16607 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16609 * regex.c (re_iswctype): Convert return values to boolean.
16611 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16613 * xdisp.c (compute_display_string_pos): Don't use cached display
16614 string position if the buffer had its restriction changed.
16617 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16619 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16621 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16623 Integer signedness and overflow and related fixes. (Bug#9079)
16625 * bidi.c: Integer size and overflow fixes.
16626 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16627 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16628 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16629 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16630 (bidi_find_other_level_edge):
16631 Use ptrdiff_t instead of EMACS_INT where either will do.
16632 This works better on 32-bit hosts configured --with-wide-int.
16633 (bidi_cache_ensure_space): Check for size-calculation overflow.
16634 Use % rather than repeated addition, for better worst-case speed.
16635 Don't set bidi_cache_size until after xrealloc returns, because it
16637 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16638 (bidi_cache_ensure_space): Also check that the bidi cache size
16639 does not exceed that of the largest Lisp string or buffer. See Eli
16640 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16642 * alloc.c (__malloc_size_t): Remove.
16643 All uses replaced by size_t. See Andreas Schwab's note
16644 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16646 * image.c: Improve checking for integer overflow.
16647 (check_image_size): Assume that f is nonnull, since
16648 it is always nonnull in practice. This is one less thing to
16649 worry about when checking for integer overflow later.
16650 (x_check_image_size): New function, which checks for integer
16651 overflow issues inside X.
16652 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16653 This removes the need for a memory_full check.
16654 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16655 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16656 (xbm_read_bitmap_data): Change locals back to 'int', since
16657 their values must fit in 'int'.
16658 (xpm_load_image, png_load, tiff_load):
16659 Invoke x_create_x_image_and_pixmap earlier,
16660 to avoid much needless work if the image is too large.
16661 (tiff_load): Treat overly large images as if
16662 x_create_x_image_and_pixmap failed, not as malloc failures.
16663 (gs_load): Use x_check_image_size.
16665 * gtkutil.c: Omit integer casts.
16666 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16667 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16669 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16671 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16672 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16673 would wrongly return t on a 64-bit host.
16675 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16676 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16677 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16678 and therefore cause GCC to emit a bogus diagnostic in some cases.
16680 * image.c: Integer signedness and overflow and related fixes.
16681 This is not an exhaustive set of fixes, but it's time to
16682 record what I've got.
16683 (lookup_pixel_color, check_image_size): Remove redundant decls.
16684 (check_image_size): Don't assume that arbitrary EMACS_INT values
16685 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16686 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16687 (tiff_load, imagemagick_load_image):
16688 Check for overflow in size calculations.
16689 (x_create_x_image_and_pixmap): Remove unnecessary test for
16690 xmalloc returning NULL; that can't happen.
16691 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16692 (xpm_color_bucket): Use better integer hashing function.
16693 (xpm_cache_color): Don't possibly over-allocate memory.
16694 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16695 (gif_memory_source):
16696 Use ptrdiff_t, not int or size_t, to record sizes.
16697 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16698 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16699 either works, as we prefer signed integers.
16700 (tiff_read_from_memory, tiff_write_from_memory):
16701 Return tsize_t, not size_t, since that's what the TIFF API wants.
16702 (tiff_read_from_memory): Don't fail simply because the read would
16703 go past EOF; instead, return a short read.
16704 (tiff_load): Omit no-longer-needed casts.
16705 (Fimagemagick_types): Don't assume size fits into 'int'.
16707 Improve hashing quality when configured --with-wide-int.
16708 * fns.c (hash_string): New function, taken from sxhash_string.
16709 Do not discard information about ASCII character case; this
16710 discarding is no longer needed.
16711 (sxhash-string): Use it. Change sig to match it. Caller changed.
16712 * lisp.h: Declare it.
16713 * lread.c (hash_string): Remove, since we now use fns.c's version.
16714 The fns.c version returns a wider integer if --with-wide-int is
16715 specified, so this should help the quality of the hashing a bit.
16717 * emacs.c: Integer overflow minor fix.
16718 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16719 Define only if GNU_LINUX.
16720 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16722 * dispnew.c: Integer signedness and overflow fixes.
16723 Remove unnecessary forward decls, that were a maintenance hassle.
16724 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16726 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16727 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16728 (prepare_desired_row, line_draw_cost):
16729 Use int, not unsigned, where either works.
16730 (save_current_matrix, restore_current_matrix):
16731 Use ptrdiff_t, not size_t, where either works.
16732 (init_display): Check for overflow more accurately, and without
16733 relying on undefined behavior.
16735 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16736 Remove, replacing with the new symbols in lisp.h. All uses changed.
16737 * fileio.c (make_temp_name):
16738 * filelock.c (lock_file_1, lock_file):
16739 * xdisp.c (message_dolog):
16740 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16741 Use pMd etc. instead.
16742 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16743 replacing the pWIDE etc. symbols removed from editfns.c.
16745 * keyboard.h (num_input_events): Now uintmax_t.
16746 This is (very slightly) less likely to mess up due to wraparound.
16749 * buffer.c: Integer signedness fixes.
16750 (alloc_buffer_text, enlarge_buffer_text):
16751 Use ptrdiff_t rather than size_t when either will do, as we prefer
16754 * alloc.c: Integer signedness and overflow fixes.
16755 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16756 (__malloc_size_t): Default to size_t, not to int.
16757 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16758 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16759 Prefer ptrdiff_t to size_t when either would do, as we prefer
16761 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16762 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16763 Now const. Initialize with values that are in range even if char
16765 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16766 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16767 These functions do the right thing with sizes > 2**32.
16768 (check_depth): Now ptrdiff_t, not int.
16769 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16770 Adjust to new way of storing sizes. Check for size overflow bugs
16772 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16773 slightly wrong anyway, as it missed one instance of
16774 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16775 (refill_memory_reserve): Omit needless cast to size_t.
16776 (mark_object_loop_halt): Mark as externally visible.
16778 * xselect.c: Integer signedness and overflow fixes.
16779 (Fx_register_dnd_atom, x_handle_dnd_message):
16780 Use ptrdiff_t, not size_t, since we prefer signed.
16781 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16782 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16783 x_dnd_atoms_size and x_dnd_atoms_length.
16785 * doprnt.c: Prefer signed to unsigned when either works.
16787 * doprnt.c (doprnt):
16789 * xdisp.c (vmessage):
16790 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16791 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16792 prefer signed arithmetic to avoid comparison confusion.
16793 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16794 but is a bit tricky.
16796 Assume freestanding C89 headers, string.h, stdlib.h.
16797 * data.c, doprnt.c, floatfns.c, print.c:
16798 Include float.h unconditionally.
16799 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16800 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16801 * regex.c: Likewise for stddef.h, string.h.
16802 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16803 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16804 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16805 (STDC_HEADERS): Remove obsolete defines.
16806 * sysdep.c: Include limits.h unconditionally.
16808 Assume support for memcmp, memcpy, memmove, memset.
16809 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16810 * regex.c (memcmp, memcpy):
16811 Remove; we assume C89 now.
16813 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16814 (__malloc_safe_bcopy): Remove; no longer needed.
16816 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16817 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16818 well either way, and we prefer signed to unsigned.
16820 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16822 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16823 closes the connection while we're reading (bug#9182).
16825 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16827 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16828 are specified (Bug#9168).
16830 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16832 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16833 Found by GCC static checking and --with-wide-int on a 32-bit host.
16835 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16837 * xdisp.c (compute_display_string_pos): Fix logic of caching
16838 previous display string position. Initialize cached_prev_pos to
16839 -1. Fixes slow-down at the beginning of a buffer.
16841 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16843 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16844 for attrs[LFACE_FONTSET_INDEX].
16846 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16848 * xml.c (parse_region): Remove unused local
16849 that was recently introduced.
16851 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16853 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16854 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16856 * xdisp.c (move_it_in_display_line_to): Record the best matching
16857 position for TO_CHARPOS while scanning the line, and restore it on
16858 exit if none of the characters scanned was an exact match.
16859 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16860 when exact match is impossible due to invisible text, and the
16861 lines are truncated.
16863 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16865 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16868 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16870 Fix a significant slow-down of cursor motion with C-n, C-p,
16871 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16872 auto-repeat under bidi redisplay in fontified buffers.
16873 * xdisp.c (compute_stop_pos_backwards): New function.
16874 (next_element_from_buffer): Call compute_stop_pos_backwards to
16875 find a suitable prev_stop when we find ourselves before
16877 (reseat): Don't look for prev_stop, as that could mean a very long
16879 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16880 <cached_disp_overlay_modiff>: Cache for last found display string
16882 (compute_display_string_pos): Return the cached position if asked
16883 about the same buffer in the same area of character positions, and
16884 the buffer wasn't changed since the time the display string
16885 position was cached.
16887 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16889 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16890 is an integer, which is important for empty lines. (Bug#9149)
16892 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16894 * frame.c (Fmodify_frame_parameters): In tty case, update the
16895 default face if necessary (Bug#4238).
16897 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16899 * editfns.c (Fstring_to_char): No need to explain what a character
16900 is in the docstring (Bug#6576).
16902 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16904 * xml.c (parse_region): Make sure we always return a tree.
16906 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16908 * xml.c (parse_region): If a document contains only comments,
16911 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16913 * xml.c (make_dom): Return comments, too.
16915 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16918 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16919 and the surrounding thread.
16920 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16921 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16922 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16924 * s/openbsd.h (BROKEN_SIGIO): Define.
16925 * unexelf.c (unexec) [__OpenBSD__]:
16926 Don't update the .mdebug section of the Alpha COFF symbol table.
16928 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16930 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16933 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16935 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16936 This fixes some race conditions on the permissions of any newly
16939 * alloc.c (valid_pointer_p): Use pipe, not open.
16940 This fixes some permissions issues when debugging.
16942 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16943 If fchown fails to set both uid and gid, try to set just gid,
16944 as that is sometimes allowed. Adjust the file's mode to eliminate
16945 setuid or setgid bits that are inappropriate if fchown fails.
16947 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16949 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

16961 symbol character follows.
16963 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16965 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16966 This works around a problem with the previous change to Fcopy_file.
16967 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16968 and without this change, GCC might complain about discarding
16969 fchown's return value.
16971 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16973 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16975 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16977 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16979 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16981 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16982 it's used from the C level.
16984 * process.c: Use the same condition for POLL_FOR_INPUT in both
16985 keyboard.c and process.c (bug#1858).
16987 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16989 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16990 (Fgnutls_boot): Use it.
16992 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16994 * doc.c (Fsubstitute_command_keys): Revert last change.
16996 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16998 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16999 quotes the next character, and doesn't affect other longer
17000 sequences (bug#8935).
17002 * lread.c (syms_of_lread): Clarify that is isn't only
17003 `eval-buffer' and `eval-defun' that's affected by
17004 `lexical-binding' (bug#8460).
17006 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17008 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17009 bidi redisplay when a line includes both an image and is truncated.
17011 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17013 Fix minor problems found by static checking.
17014 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17015 (elsz): Now a signed constant, not a size_t var. We prefer signed
17016 types to unsigned, to avoid integer comparison confusion. Without
17017 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17018 "cannot optimize loop, the loop counter may overflow", a symptom
17020 * indent.c (Fvertical_motion): Mark locals as initialized.
17021 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17023 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
17025 * search.c (Fre_search_backward): Mention `case-fold-search' in
17026 all the re_search_* functions (bug#8138).

17049 (display_string): If we need to ignore text properties of
17050 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17051 original value of -1 will not work with bidi.)
17052 (compute_display_string_pos): First arg is now struct
17053 `text_pos *'; all callers changed. Support display properties on
17055 (compute_display_string_end): Support display properties on Lisp
17057 (init_iterator, reseat_1, reseat_to_string): Initialize the
17058 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
17059 when iterating on a string not from display properties).
17060 (compute_display_string_pos, compute_display_string_end):
17061 Fix calculation of the object to scan. Fixes an error when using
17063 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
17064 base_level_stop; instead, set base_level_stop to BEGV.
17065 Fixes crashes in vertical-motion.
17066 (next_element_from_buffer): Improve commentary for when
17067 the iterator is before prev_stop.
17068 (init_iterator): Initialize bidi_p from the default value of
17069 bidi-display-reordering, not from buffer-local value. Use the
17070 buffer-local value only if initializing for buffer iteration.
17071 (handle_invisible_prop): Support invisible properties on strings
17072 that are being bidi-reordered.

17080 (init_iterator): Don't initialize it->bidi_p for strings
17082 (reseat_to_string): Initialize it->bidi_p for strings here.

17091 parts of next_element_from_buffer, next_element_from_string, and
17092 next_element_from_c_string.
17093 (tool_bar_lines_needed, redisplay_tool_bar)
17094 (display_menu_bar): Force left-to-right direction. Add a FIXME
17095 comment for making that be controlled by a user option.

17109 pushed the iterator stack, restore the internal state of the bidi
17110 iterator by calling bidi_pop_it same number of times.
17111 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
17112 and we are bidi-iterating, don't decrement the iterator position;
17113 instead, set the first_elt flag in the bidi iterator, to produce
17115 (reseat_1): Remove redundant setting of string_from_display_prop_p.
17116 (push_display_prop): xassert that we are iterating a buffer.
17117 (push_it, pop_it): Save and restore paragraph_embedding member.
17118 (handle_single_display_spec, next_overlay_string)
17119 (get_overlay_strings_1, reseat_1, reseat_to_string)
17120 (push_display_prop): Set up the `unibyte' member of bidi_it.string
17121 correctly. Don't assume unibyte strings are not bidi-reordered.

17130 property. Fix a typo in popping stretch info. Add an assertion
17131 for verifying that the iterator position is in sync with the bidi
17133 (handle_single_display_spec, get_overlay_strings_1)

17278 The old code sometimes used this field without initializing it.
17280 * alloc.c (gc_sweep): Don't read past end of array.
17281 In theory, the old code could also have corrupted Emacs internals,
17282 though it'd be very unlikely.

17286 * character.c (Fcharacterp): Don't advertise optional ignored
17287 argument. (Bug#4026)

17545 (clone_per_buffer_values): Don't assume that

17547 This isn't true in general, and it's particularly not true
17548 if Emacs is configured with --with-wide-int.
17549 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
17550 New macros, used in the buffer.c change.

17586 Random fixes. E.g., (random) never returned negative values.
17587 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17588 subseconds part to the entropy, as that's a bit more random.
17589 Prefer signed to unsigned, since the signedness doesn't matter and
17590 in general we prefer signed. When given a limit, use a
17591 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17592 latter isn't right if USE_2_TAGS_FOR_INTS.
17593 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17594 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17606 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
17607 This is more efficient than Ffile_directory_p and avoids a minor race.
17609 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
17611 * buffer.c (Foverlay_put): Say what the return value is
17614 * fileio.c (barf_or_query_if_file_exists): Check first if the file
17615 is a directory before asking whether to use the file name
17617 (barf_or_query_if_file_exists): Make the "File is a directory"
17618 error be more correct.
17620 * fns.c (Frequire): Remove the mention of the .gz files, since
17621 that's installation-specific, but keep the mention of
17622 `get-load-suffixes'.

17626 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

17634 Qgnutls_bootprop_verify_error (which is no longer used).
17636 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
17637 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17638 Also (re)move comments that are misplaced or no longer relevant.

17665 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
17667 * lread.c (syms_of_lread): Mention single symbols defined by

17701 (syms_of_keymap): Defsubr make-composed-keymap.
17702 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

17739 * eval.c (struct backtrace): Simplify and port the data structure.
17740 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17741 signed bit field, as this assumption is not portable and it makes
17742 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17743 "char debug_on_exit : 1" as this is not portable either; instead,
17744 use the portable "unsigned int debug_on_exit : 1". Remove unused
17745 member evalargs. Remove obsolete comments about cc bombing out.
17747 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

17913 * print.c (printchar, strout): Check for string overflow.
17914 (PRINTPREPARE, printchar, strout):
17915 Don't set size unless allocation succeeds.
17917 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17918 for sizes. Check for string overflow more accurately.
17919 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
17921 * macros.c: Integer and buffer overflow fixes.
17922 * keyboard.h (struct keyboard.kbd_macro_bufsize):
17923 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

17927 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
17929 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
17931 * lread.c: Integer overflow fixes.
17932 (read_integer): Radix is now EMACS_INT, not int,
17933 to improve quality of diagnostics for out-of-range radices.
17934 Calculate buffer size correctly for out-of-range radices.
17935 (read1): Check for integer overflow in radices, and in
17936 read-circle numbers.
17937 (read_escape): Avoid int overflow.
17938 (Fload, openp, read_buffer_size, read1)
17939 (substitute_object_recurse, read_vector, read_list, map_obarray):

17955 2011-06-22 Leo Liu <sdl.web@gmail.com>
17957 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17958 Move to minibuffer.el.
17960 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17962 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17963 The following patches are for when GLYPH_DEBUG && !XASSERT.
17964 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17965 * dispnew.c (flush_stdout):
17966 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17967 Mark as externally visible.
17968 * dispnew.c (check_window_matrix_pointers): Now static.
17969 * dispnew.c (window_to_frame_vpos):
17970 * xfns.c (unwind_create_frame):
17971 * xterm.c (x_check_font): Remove unused local.
17972 * scroll.c (CHECK_BOUNDS):
17973 * xfaces.c (cache_fache): Rename local to avoid shadowing.
17974 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
17975 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
17976 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
17977 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17979 (debug_method_add): Use va_list and vsprintf rather than relying
17980 on undefined behavior with wrong number of arguments.
17981 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17982 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17983 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17984 since we're not interested in debugging glyphs with old libraries.
17985 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17986 GCC 4.6.0's static checking.
17988 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17990 Integer overflow and signedness fixes (Bug#8873).

18006 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
18007 (.bitmaps_last, struct x_output.icon_bitmap):
18008 Use ptrdiff_t, not int, for bitmap indexes.
18009 (x_allocate_bitmap_record): Check for size overflow.
18010 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
18012 Use ptrdiff_t, not int, for overlay counts.
18013 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
18014 * editfns.c (overlays_around, get_pos_property):
18015 * textprop.c (get_char_property_and_overlay):
18016 * xdisp.c (next_overlay_change, note_mouse_highlight):
18017 * xfaces.c (face_at_buffer_position):
18018 * buffer.c (OVERLAY_COUNT_MAX): New macro.
18019 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
18020 (Fnext_overlay_change, Fprevious_overlay_change)
18021 (mouse_face_overlay_overlaps, Foverlays_in):
18022 Use ptrdiff_t, not int, for sizes.
18023 (overlays_at, overlays_in): Check for size-calculation overflow.
18025 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18027 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18028 (x_session_initialize): Do not assume string length fits in int.
18030 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18031 This is unlikely, but can occur if DPI is outlandish.
18033 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
18034 * xselect.c (Fx_get_atom_name): Avoid need for strlen.

18037 * xrdb.c (magic_file_p, search_magic_path):
18038 Omit last arg SUFFIX; it was always 0. All callers changed.
18039 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18041 * xfont.c (xfont_match): Avoid need for strlen.
18043 * xfns.c: Don't assume strlen fits in int.

18046 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18047 not unsigned long, as we prefer signed integers. All callers changed.
18048 Detect integer overflow in repeat count.
18049 (message_dolog): Don't assume print length fits in 39 bytes.
18050 (display_mode_element): Don't assume strlen fits in int.
18052 * termcap.c: Don't assume sizes fit in int and never overflow.
18053 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
18054 (gobble_line): Check for size-calculation overflow.
18056 * minibuf.c (Fread_buffer):
18057 * lread.c (intern, intern_c_string):
18058 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

18071 * filelock.c: Fix some buffer overrun and integer overflow issues.
18072 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18073 Reformulate so as not to need the command string.
18074 Invoke gzip -cd rather than gunzip, as it's more portable.
18075 (lock_info_type, lock_file_1, lock_file):
18076 Don't assume pid_t and time_t fit in unsigned long.
18077 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18078 (current_lock_owner): Prefer signed type for sizes.
18079 Use memcpy, not strncpy, where memcpy is what is really wanted.
18080 Don't assume (via atoi) that time_t and pid_t fit in int.
18081 Check for time_t and/or pid_t out of range, e.g., via a network share.
18082 Don't alloca where an auto var works fine.
18084 * fileio.c: Fix some integer overflow issues.
18085 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18086 Don't assume string length fits in int.
18087 (directory_file_name): Don't assume string length fits in long.
18088 (make_temp_name): Don't assume pid fits in int, or that its print
18089 length is less than 20.

18108 (Fgetenv_internal):
18109 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18111 * lread.c (invalid_syntax): Omit length argument.
18112 All uses changed. This doesn't fix a bug, but it simplifies the
18113 code away from its former Hollerith-constant appearance, and it's
18114 one less 'int' to worry about when looking at integer-overflow issues.
18115 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18117 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18118 This didn't break anything, but it didn't help either.
18119 It's confusing to put a bogus integer in a place where the actual
18120 value does not matter.
18121 (LIST_END_P): Remove unused macro and its bogus comment.
18122 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18124 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18125 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18127 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18128 We prefer signed types, and the value cannot exceed the EMACS_INT
18129 range anyway (because otherwise the length would not be representable).
18130 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18131 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18132 This avoids a GCC warning when WIDE_EMACS_INT.
18134 * indent.c (sane_tab_width): New function.
18135 (current_column, scan_for_column, Findent_to, position_indentation)
18136 (compute_motion): Use it. This is just for clarity.
18137 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18139 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
18141 * lisp.h (lint_assume): New macro.
18142 * composite.c (composition_gstring_put_cache):
18143 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18145 * editfns.c, insdel.c:
18146 Omit unnecessary forward decls, to simplify future changes.
18148 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18150 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18152 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18153 Use much-faster test for byte-length change.
18154 Don't assume string byte-length fits in 'int'.
18155 Check that character arg fits in 'int'.
18156 (mapcar1): Declare byte as byte, for clarity.
18158 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18160 * fns.c (concat): Catch string overflow earlier.
18161 Do not rely on integer wraparound.
18163 * dispextern.h (struct it.overlay_strings_charpos)
18164 (struct it.selective): Now EMACS_INT, not int.
18165 * xdisp.c (forward_to_next_line_start)
18166 (back_to_previous_visible_line_start)
18167 (reseat_at_next_visible_line_start, next_element_from_buffer):
18168 Don't arbitrarily truncate the value of 'selective' to int.
18170 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18172 * composite.c: Don't truncate sizes to 'int'.
18173 (composition_gstring_p, composition_reseat_it)
18174 (composition_adjust_point): Use EMACS_INT, not int.
18175 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18176 not EMACS_UINT, for indexes.
18178 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18180 * buffer.c: Include <verify.h>.
18181 (struct sortvec.priority, struct sortstr.priority):
18182 Now EMACS_INT, not int.
18183 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18184 (struct sortstr.size, record_overlay_string)
18185 (struct sortstrlist.size, struct sortlist.used):
18186 Don't truncate size to int.
18187 (record_overlay_string): Check for size-calculation overflow.
18188 (init_buffer_once): Check at compile-time, not run-time.
18190 2011-06-22 Jim Meyering <meyering@redhat.com>
18192 Don't leak an XBM-image-sized buffer
18193 * image.c (xbm_load): Free the image buffer after using it.
18195 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18198 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18199 that Sun C diagnosed.
18200 * fns.c (secure_hash): Fix pointer signedness issue.
18201 * intervals.c (static_offset_intervals): New function.
18202 (offset_intervals): Use it.
18204 2011-06-21 Leo Liu <sdl.web@gmail.com>
18207 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18210 * fns.c (secure_hash): Rename from crypto_hash_function and change
18211 the first arg to accept symbols.
18212 (Fsecure_hash): New primitive.
18213 (syms_of_fns): New symbols.
18215 2011-06-20 Deniz Dogan <deniz@dogan.se>
18217 * process.c (Fset_process_buffer): Clarify return value in
18220 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18222 * dispnew.c (add_window_display_history): Use BVAR.
18224 * xdisp.c (debug_method_add): Use BVAR.
18225 (check_window_end, dump_glyph_matrix, dump_glyph)
18226 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18228 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18231 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18232 check till after the cache is created in init_frame_faces.
18234 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18236 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18238 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18240 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18241 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18242 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18244 Improve buffer-overflow checking (Bug#8873).
18245 * fileio.c (Finsert_file_contents):
18246 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18247 Remove the old (too-loose) buffer overflow checks.
18248 They weren't needed, since make_gap checks for buffer overflow.
18249 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18250 The old code merely checked for Emacs fixnum overflow, and relied
18251 on undefined (wraparound) behavior. The new code avoids undefined
18252 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18254 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18255 Tune. Don't use wider integers than needed. Don't use alloca.
18256 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18258 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18260 * insdel.c, lisp.h (buffer_overflow): New function.
18261 (insert_from_buffer_1, replace_range, replace_range_2):
18262 * insdel.c (make_gap_larger):
18263 * editfns.c (Finsert_char):
18264 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18266 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18268 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18270 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18272 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18273 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18275 * fileio.c: Don't assume EMACS_INT fits in off_t.
18276 (emacs_lseek): New static function.
18277 (Finsert_file_contents, Fwrite_region): Use it.
18278 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18280 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18282 * fns.c: Don't overflow int when computing a list length.
18283 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18284 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18285 truncation on 64-bit hosts. Check for QUIT every
18286 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18287 faster and is responsive enough.
18288 (Flength): Report an error instead of overflowing an integer.
18289 (Fsafe_length): Return a float if the value is not representable
18290 as a fixnum. This shouldn't happen except in contrived situations.
18291 (Fnthcdr, Fsort): Don't assume list length fits in int.
18292 (Fcopy_sequence): Don't assume vector length fits in int.
18294 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18295 (header_size, word_size): New constants.
18296 (allocate_vectorlike): Don't check size overflow here.
18297 (allocate_vector): Check it here instead, since this is the only
18298 caller of allocate_vectorlike that could cause overflow.
18299 Check that the new vector's length is representable as a fixnum.
18301 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18302 The previous code was bogus. For example, next_almost_prime (32)
18303 returned 39, which is undesirable as it is a multiple of 3; and
18304 next_almost_prime (24) returned 25, which is a multiple of 5 so
18305 why was the code bothering to check for multiples of 7?
18307 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18309 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18311 Variadic C functions now count arguments with ptrdiff_t.
18312 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18313 Back then I didn't know that the Emacs coding style prefers signed int.
18314 Also, in the meantime I found a few more instances where arguments
18315 were being counted with int, which may truncate counts on 64-bit
18316 machines, or EMACS_INT, which may be unnecessarily wide.
18317 * lisp.h (struct Lisp_Subr.function.aMANY)
18318 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18319 Arg counts are now ptrdiff_t, not size_t.
18320 All variadic functions and their callers changed accordingly.
18321 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18322 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18323 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18324 * callint.c (Fcall_interactively): Check arg count for overflow,
18325 to avoid potential buffer overrun. Use signed char, not 'int',
18326 for 'varies' array, so that we needn't bother to check its size
18327 calculation for overflow.
18328 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18329 * eval.c (apply_lambda):
18330 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18331 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18332 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18334 * callint.c (Fcall_interactively): Don't use index var as event count.
18336 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18337 * mem-limits.h (SIZE): Remove; no longer used.
18339 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18341 Remove unnecessary casts.
18342 * xterm.c (x_term_init):
18343 * xfns.c (x_set_border_pixel):
18344 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18345 These aren't needed now that we assume ANSI C.
18347 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18348 It's more likely to cause problems (due to unsigned overflow)
18351 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18353 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18355 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18357 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18359 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18361 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18363 GLYPH_CODE_FACE returns EMACS_INT, not int.
18364 * dispextern.h (merge_faces):
18365 * xfaces.c (merge_faces):
18366 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18367 Don't assume EMACS_INT fits in int.
18369 * character.h (CHAR_VALID_P): Remove unused parameter.
18370 * fontset.c, lisp.h, xdisp.c: All uses changed.
18372 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18374 * fns.c (concat): Minor tuning based on overflow analysis.
18375 This doesn't fix any bugs. Use int to hold character, instead
18376 of constantly refetching from Emacs object. Use XFASTINT, not
18377 XINT, for value known to be a character. Don't bother comparing
18378 a single byte to 0400, as it's always less.
18380 * floatfns.c (Fexpt):
18381 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18383 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18386 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18388 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18389 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18390 incorrectly succeed when S was a string, because 4294967386 was
18391 truncated before it was used.
18393 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18394 Otherwise, an out-of-range integer could cause undefined behavior
18397 * composite.c: Use int, not EMACS_INT, for characters.
18398 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18399 EMACS_INT, for values that are known to be in character range.
18400 This doesn't fix any bugs but is the usual style inside Emacs and
18401 may generate better code on 32-bit machines.
18403 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18404 This is for reasons similar to the recent CHAR_STRING fix.
18405 * charset.c (Fencode_char): Check that character arg is actually
18406 a character. Pass an int to ENCODE_CHAR.
18407 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18408 wider than 'int', as a compile-time check to prevent future regressions
18411 * character.c (char_string): Remove unnecessary casts.
18413 Make sure a 64-bit char is never passed to CHAR_STRING.
18414 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18415 by silently ignoring the top 32 bits, allowing some values
18416 that were far too large to be valid characters.
18417 * character.h: Include <verify.h>.
18418 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18419 arguments are no wider than unsigned, as a compile-time check
18420 to prevent future regressions in this area.
18422 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18423 (Fsubst_char_in_region):
18425 * xdisp.c (decode_mode_spec_coding):
18426 Adjust to CHAR_STRING's new requirement.
18427 * editfns.c (Finsert_char, Fsubst_char_in_region):
18428 * fns.c (concat): Check that character args are actually
18429 characters. Without this test, these functions did the wrong
18430 thing with wildly out-of-range values on 64-bit hosts.
18432 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18433 These casts should not be needed on 32-bit hosts, either.
18434 * keyboard.c (read_char):
18435 * lread.c (Fload): Remove casts to unsigned.
18437 * lisp.h (UNSIGNED_CMP): New macro.
18438 This fixes comparison bugs on 64-bit hosts.
18439 (ASCII_CHAR_P): Use it.
18440 * casefiddle.c (casify_object):
18441 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18442 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18443 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18444 * dispextern.h (FACE_FROM_ID):
18445 * keyboard.c (read_char): Use UNSIGNED_CMP.
18447 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18448 not to EMACS_INT, to avoid GCC warning.
18450 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18452 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18453 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18454 isn't needed on 32-bit machines.
18456 * buffer.c (Fgenerate_new_buffer_name):
18457 Use EMACS_INT for count, not int.
18458 (advance_to_char_boundary): Return EMACS_INT, not int.
18460 * data.c (Qcompiled_function): Now static.
18462 * window.c (window_body_lines): Now static.
18464 * image.c (gif_load): Rename local to avoid shadowing.
18466 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18467 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18468 * alloc.c (make_save_value): Integer argument is now of type
18469 ptrdiff_t, not int.
18470 (mark_object): Use ptrdiff_t, not int.
18471 * lisp.h (pD): New macro.
18472 * print.c (print_object): Use it.
18474 * alloc.c: Use EMACS_INT, not int, to count objects.
18475 (total_conses, total_markers, total_symbols, total_vector_size)
18476 (total_free_conses, total_free_markers, total_free_symbols)
18477 (total_free_floats, total_floats, total_free_intervals)
18478 (total_intervals, total_strings, total_free_strings):
18479 Now EMACS_INT, not int. All uses changed.
18480 (Fgarbage_collect): Compute overall total using a double, so that
18481 integer overflow is less likely to be a problem. Check for overflow
18482 when converting back to an integer.
18483 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18484 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18485 These were 'int' variables that could overflow on 64-bit hosts;
18486 they were never used, so remove them instead of repairing them.
18487 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18488 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18489 Previously, this ceilinged at INT_MAX, but that doesn't work on
18491 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18493 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18494 (allocate_vectorlike): Check for ptrdiff_t overflow.
18495 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18496 when a (possibly-narrower) signed value would do just as well.
18497 We prefer using signed arithmetic, to avoid comparison confusion.
18499 * alloc.c: Catch some string size overflows that we were missing.
18500 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18501 for convenience in STRING_BYTES_MAX.
18502 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18503 The definition here is exact; the one in lisp.h was approximate.
18504 (allocate_string_data): Check for string overflow. This catches
18505 some instances we weren't catching before. Also, it catches
18506 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18507 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18508 and ptrdiff_t and EMACS_INT are both 64 bits.
18510 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18511 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18512 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18514 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18516 * alloc.c (Fmake_string): Check for out-of-range init.
18518 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18520 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18522 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18524 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18525 xg_get_default_scrollbar_width.
18527 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18528 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18529 (style_changed_cb): Call update_theme_scrollbar_width and call
18530 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18531 all frames (Bug#8505).
18532 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
18533 Call gtk_window_set_resizable if HAVE_GTK3.
18534 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
18535 and height if HAVE_GTK3 (Bug#8505).
18536 (scroll_bar_width_for_theme): New variable.
18537 (update_theme_scrollbar_width): New function.
18538 (xg_get_default_scrollbar_width): Move code to
18539 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18540 (xg_initialize): Call update_theme_scrollbar_width.
18542 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18544 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18546 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18548 * frame.c (make_frame): Call other_buffer_safely instead of
18551 * window.c (temp_output_buffer_show): Call display_buffer with
18552 second argument Vtemp_buffer_show_specifiers and reset latter
18553 immediately after the call.
18554 (Vtemp_buffer_show_specifiers): New variable.
18555 (auto_window_vscroll_p, next_screen_context_lines)
18556 (Vscroll_preserve_screen_position): Remove leading asterisks from
18559 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
18561 Fix minor problems found by GCC 4.6.0 static checking.
18562 * buffer.c (Qclone_number): Remove for now, as it's unused.
18563 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
18564 (record_buffer): Remove unused local.
18565 * frame.c (other_visible_frames, frame_buffer_list): Now static.
18566 (set_frame_buffer_list): Remove; unused.
18567 * frame.h (other_visible_frames): Remove decl.
18568 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
18569 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
18570 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
18572 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
18573 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
18574 Define only if HAVE_GPM.
18575 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
18576 (update_hints_inhibit): Remove; never set. All uses removed.
18577 * widgetprv.h (emacsFrameClassRec): Remove decl.
18578 * window.c (delete_deletable_window): Now returns void, since it
18579 wasn't returning anything.
18580 (compare_window_configurations): Remove unused locals.
18581 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
18582 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
18583 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
18584 the same widths as pointers. This follows up on the 2011-05-06 patch.
18585 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
18586 * xterm.h: Likewise.
18587 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
18589 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
18591 * makefile.w32-in: Update dependencies.
18592 (LISP_H): Add lib/intprops.h.
18594 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
18596 * image.c (gif_load): Add animation frame delay to the metadata.
18597 (syms_of_image): Use DEFSYM. New symbol `delay'.
18599 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18601 * window.c (delete_deletable_window): Re-add.
18602 (Fset_window_configuration): Rewrite to handle dead buffers and
18603 consequently deletable windows.
18604 (window_tree, Fwindow_tree): Remove. Supply functionality in
18606 (compare_window_configurations): Simplify code.
18608 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
18610 * image.c (imagemagick_load_image): Fix type mismatch.
18611 (Fimagemagick_types): Likewise.
18613 * window.h (replace_buffer_in_windows): Declare.
18615 2011-06-11 Martin Rudalics <rudalics@gmx.at>
18617 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
18618 Qclone_number. Remove external declaration of Qdelete_window.
18619 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
18621 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
18622 Run Qbuffer_list_update_hook if allowed.
18623 (Fother_buffer): Rewrite doc-string. Major rewrite for new
18624 buffer list implementation.
18625 (other_buffer_safely): New function.
18626 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
18627 calls to replace_buffer_in_windows and
18628 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
18630 (record_buffer): Inhibit quitting and rewrite using quittable
18631 functions. Run Qbuffer_list_update_hook if allowed.
18632 (Frecord_buffer, Funrecord_buffer): New functions.
18633 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
18634 Move switch-to-buffer to window.el.
18635 (bury-buffer): Move to window.el.
18636 (Vbuffer_list_update_hook): New variable.
18638 * lisp.h (other_buffer_safely): Add prototype in buffer.c
18641 * window.h (resize_frame_windows): Move up in code.
18642 (Fwindow_frame): Remove EXFUN.
18643 (replace_buffer_in_all_windows): Remove prototype.
18644 (replace_buffer_in_windows_safely): Add prototype.
18646 * window.c: Declare Qdelete_window static again. Move down
18647 declaration of select_count.
18648 (Fnext_window, Fprevious_window): Rewrite doc-strings.
18649 (Fother_window): Move to window.el.

19097 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
19098 bidi_it->nchars is non-positive.
19099 (bidi_level_of_next_char): Don't try to lookup the cache for the
19100 next/previous character if nothing is cached there yet, or if we
19101 were just reseat()'ed to a new position.
19103 * xdisp.c (set_cursor_from_row): Set start and stop points
19104 according to the row's direction when priming the loop that looks
19105 for the glyph on which to display cursor.
19106 (single_display_spec_intangible_p): Function deleted.
19107 (display_prop_intangible_p): Reimplement to call
19108 handle_display_spec instead of single_display_spec_intangible_p.
19109 Accept 3 additional arguments needed by handle_display_spec.
19110 This fixes incorrect cursor motion across display property with complex
19111 values: lists, `(when COND...)' forms, etc.
19112 (single_display_spec_string_p): Support property values that are
19113 lists with the argument STRING its top-level element.
19114 (display_prop_string_p): Fix the condition for processing a
19115 property that is a list to be consistent with handle_display_spec.
19116 (handle_display_spec): New function, refactored from the
19117 last portion of handle_display_prop.
19118 (compute_display_string_pos): Accept additional argument
19119 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
19120 value of a `display' property is a "replacing spec".
19121 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19122 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
19123 the display property, but just return a value indicating whether
19124 the display property will replace the characters it covers.
19125 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
19126 frame_window_p members of struct bidi_it.
19127 (compute_display_string_pos, compute_display_string_end):
19129 (push_it): Accept second argument POSITION, where pop_it should
19130 jump to continue iteration.
19131 (reseat_1): Initialize bidi_it.disp_pos.
19133 * keyboard.c (adjust_point_for_property): Adjust the call to
19134 display_prop_intangible_p to its new signature.
19136 * dispextern.h (struct bidi_it): New member frame_window_p.
19137 (bidi_init_it): Update prototypes.

19146 Malloc failure behavior now depends on size of allocation.
19147 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
19148 * lisp.h: Change signatures accordingly.
19149 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
19150 All callers changed. (Bug#8762)
19152 * gnutls.c: Use Emacs's memory allocators.
19153 Without this change, the gnutls library would invoke malloc etc.
19154 directly, which causes problems on non-SYNC_INPUT hosts, and which
19155 runs afoul of improving memory_full behavior. (Bug#8761)
19156 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19157 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19158 xfree instead of the default malloc, realloc, free.
19159 (Fgnutls_boot): No need to check for memory allocation failure,
19160 since xmalloc does that for us.
19162 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

19180 * lisp.h (struct Lisp_Hash_Table):
19181 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
19182 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
19183 for hashes and hash indexes, instead of 'unsigned' and 'int'.
19184 * alloc.c (allocate_vectorlike):
19185 Check for overflow in vector size calculations.
19186 * ccl.c (ccl_driver):
19187 Check for overflow when converting EMACS_INT to int.
19188 * fns.c, image.c: Remove unnecessary static decls that would otherwise
19189 need to be updated by these changes.
19190 * fns.c (make_hash_table, maybe_resize_hash_table):
19191 Check for integer overflow with large hash tables.
19192 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19193 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19194 (SXHASH_REDUCE): New macro.
19195 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19196 Use it instead of discarding useful hash info with large hash values.
19197 (sxhash_float): New function.
19198 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19199 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19200 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19201 Rewrite to use FIXNUM_BITS, as this simplifies things.
19202 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19203 Adjust signatures to match updated version of code.
19204 (consing_since_gc): Now EMACS_INT, since a single hash table can
19205 use more than INT_MAX bytes.
19207 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
19209 Make it possible to build with GCC-4.6+ -O2 -flto.
19211 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
19213 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
19215 * minibuf.c (get_minibuffer, read_minibuf_unwind):
19216 Call minibuffer-inactive-mode.
19218 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
19220 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
19221 Update dependencies.
19223 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19225 * data.c (init_data): Remove code for UTS, this system is not
19228 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19230 Don't force ./temacs to start in terminal mode.
19232 * frame.c (make_initial_frame): Initialize faces in all cases, not
19233 only when CANNOT_DUMP is defined.
19234 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
19236 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19238 * dispnew.c (add_window_display_history): Use const for the string
19239 pointer. Remove declaration, not needed.
19241 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19243 Use 'inline', not 'INLINE'.
19244 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
19245 * alloc.c, fontset.c (INLINE): Remove.
19246 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
19247 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
19248 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
19249 * gmalloc.c (register_heapinfo): Use inline unconditionally.
19250 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
19252 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19254 Make it possible to run ./temacs.
19256 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19257 syms_of_callproc does the same thing. Remove test for
19258 "initialized", do it in the caller.
19259 * emacs.c (main): Avoid calling set_initial_environment when dumping.
19261 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
19263 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
19264 (read_minibuf): Use get_minibuffer.
19265 (syms_of_minibuf): Use DEFSYM.
19266 (Qmetadata): New var.
19267 * data.c (Qbuffer): Don't make it static.
19268 (syms_of_data): Use DEFSYM.
19270 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19272 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
19273 (CCL_CODE_MIN): New macro.
19275 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
19277 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
19279 * eval.c (Qdebug): Now static.
19280 * lisp.h (Qdebug): Remove decl. This reverts a part of the
19281 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
19282 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
19284 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19286 * image.c: Various fixes to ImageMagick code comments.
19287 (Fimagemagick_types): Doc fix.
19289 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
19291 Minor fixes prompted by GCC 4.6.0 warnings.
19293 * xselect.c (converted_selections, conversion_fail_tag): Now static.
19295 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
19296 (x_clipboard_manager_save_all): Move extern decl to ...
19297 * xterm.h: ... here, so that it can be checked for consistency.
19299 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19301 * xselect.c (x_clipboard_manager_save_frame)
19302 (x_clipboard_manager_save_all): New functions.
19303 (Fx_clipboard_manager_save): Lisp function deleted.
19305 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
19306 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
19308 * xterm.h: Update prototype.
19310 2011-05-28 William Xu <william.xwl@gmail.com>
19312 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
19313 exiting (Bug#8239).
19315 2011-05-28 Jim Meyering <meyering@redhat.com>
19317 Avoid a sign-extension bug in crypto_hash_function.
19318 * fns.c (to_uchar): Define.
19319 (crypto_hash_function): Use it to convert some newly-signed
19320 variables to unsigned, to avoid sign-extension bugs. For example,
19321 without this change, (md5 "truc") would evaluate to
19322 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19323 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19324 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19326 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19328 Integer overflow fixes.
19330 * dbusbind.c: Serial number integer overflow fixes.
19331 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19332 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19333 to hold a serial number that is too large for a fixnum.
19334 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19335 Check for serial numbers out of range. Decode any serial number
19336 that was so large that it became a float. (Bug#8722)
19338 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19339 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19340 Use XFASTINT rather than XUINT when numbers are nonnegative.
19341 (xd_append_arg, Fdbus_method_return_internal):
19342 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19343 arguments, check that Lisp number is nonnegative, rather than
19344 silently wrapping negative numbers around. (Bug#8722)
19345 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19348 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19350 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19352 ccl: Add integer overflow checks.
19353 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19354 (IN_INT_RANGE): New macros.
19355 (ccl_driver): Use them to check for integer overflow when
19356 decoding a CCL program. Many of the new checks are whether XINT (x)
19357 fits in int; it doesn't always, on 64-bit hosts. The new version
19358 doesn't catch all possible integer overflows, but it's an
19359 improvement. (Bug#8719)
19361 * alloc.c (make_event_array): Use XINT, not XUINT.
19362 There's no need for unsigned here.
19364 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19365 This follows up to the 2011-05-06 change that substituted uintptr_t
19366 for EMACS_INT. This case wasn't caught back then.
19368 Rework Fformat to avoid integer overflow issues.
19369 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19370 now (part of C89). Include <verify.h>.
19371 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19372 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19373 (Fformat): Avoid the prepass trying to compute sizes; it was only
19374 approximate and thus did not catch overflow reliably. Instead, walk
19375 through the format just once, formatting and computing sizes as we go,
19376 checking for integer overflow at every step, and allocating a larger
19377 buffer as needed. Keep track separately whether the format is
19378 multibyte. Keep only the most-recently calculated precision, rather
19379 than them all. Record whether each argument has been converted to
19380 string. Use EMACS_INT, not int, for byte and char and arg counts.
19381 Support field widths and precisions larger than INT_MAX. Avoid
19382 sprintf's undefined behavior with conversion specifications such as %#d
19383 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19384 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19385 formatting out-of-range floating point numbers with int
19386 formats. (Bug#8668)
19388 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19390 * data.c: Avoid integer truncation in expressions involving floats.
19391 * data.c: Include <intprops.h>.
19392 (arith_driver): When there's an integer overflow in an expression
19393 involving floating point, convert the integers to floating point
19394 so that the resulting value does not suffer from catastrophic
19395 integer truncation. For example, on a 64-bit host (* 4
19396 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19397 Do not rely on undefined behavior after integer overflow.
19399 merge count_size_as_multibyte, parse_str_to_multibyte
19400 * character.c, character.h (count_size_as_multibyte):
19401 Rename from parse_str_to_multibyte; all uses changed.
19402 Check for integer overflow.
19403 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19404 since it's now a duplicate of the other. This is more of
19405 a character than a buffer op, so better that it's in character.c.
19406 * fns.c, print.c: Adjust to above changes.
19408 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19410 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19412 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19414 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19415 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19416 (x_clipboard_manager_save): Now static.
19417 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19419 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19420 (crypto_hash_function): Now static.
19421 Fix pointer signedness problems. Avoid unnecessary initializations.
19423 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19425 * termhooks.h (Vselection_alist): Make it terminal-local.
19427 * terminal.c (create_terminal): Initialize it.
19429 * xselect.c: Support for clipboard managers.
19430 (Vselection_alist): Move to termhooks.h as terminal-local var.
19431 (LOCAL_SELECTION): New macro.
19432 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19433 (symbol_to_x_atom): Remove gratuitous arg.
19434 (x_handle_selection_request, lisp_data_to_selection_data)
19435 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19436 (x_own_selection, x_get_local_selection, x_convert_selection):
19437 New arg, specifying work frame. Use terminal-local Vselection_alist.
19438 (some_frame_on_display): Delete unused function.
19439 (Fx_own_selection_internal, Fx_get_selection_internal)
19440 (Fx_disown_selection_internal, Fx_selection_owner_p)
19441 (Fx_selection_exists_p): New optional frame arg.
19442 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19443 (x_handle_selection_clear): Don't treat other terminals with the
19444 same keyboard specially. Use the terminal-local Vselection_alist.
19445 (x_clear_frame_selections): Use Frun_hook_with_args.
19447 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19449 * xterm.h: Add support for those atoms.
19451 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19453 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19454 (converted_selections, conversion_fail_tag): New global variables.
19455 (x_selection_request_lisp_error): Free the above.
19456 (x_get_local_selection): Remove unnecessary code.
19457 (x_reply_selection_request): Args changed; handle arbitrary array
19458 of converted selections stored in converted_selections.
19459 Separate the XChangeProperty and SelectionNotify steps.
19460 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19461 (x_convert_selection): New function.
19462 (x_handle_selection_event): Simplify.
19463 (x_get_foreign_selection): Don't ignore incoming requests while
19464 waiting for an answer; this will fail when we implement
19465 SAVE_TARGETS, and seems unnecessary anyway.
19466 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19467 (Vx_sent_selection_functions): Doc fix.
19469 2011-05-26 Leo Liu <sdl.web@gmail.com>
19471 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19473 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19475 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19477 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19478 for fringe update if it has periodic bitmap.
19479 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19480 and fringe_bitmap_periodic_p.
19482 * fringe.c (get_fringe_bitmap_data): New function.
19483 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19484 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19485 row. Mark glyph row for fringe update if periodicity changed.
19487 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19488 for fringe update unless it has periodic bitmap.
19490 2011-05-25 Kenichi Handa <handa@m17n.org>
19492 * xdisp.c (get_next_display_element): Set correct it->face_id for
19493 a static composition.

19506 * gnutls.c: Remove unused macros.
19507 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19508 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19509 Remove macros that are defined and never used.
19510 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19512 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19514 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19515 (Fx_get_selection_internal): Minor cleanup.
19516 (Fx_own_selection_internal): Rename arguments for consistency with

19525 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19527 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19529 * dispnew.c (scrolling_window): Don't exclude the case that the
19530 last enabled row in the desired matrix touches the bottom boundary.
19532 2011-05-21 Glenn Morris <rgm@gnu.org>
19534 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19535 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19536 and add some more files.
19538 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19540 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19541 report_file_error introduced by the change from 2011-05-07.
19543 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19545 * systime.h (Time): Define only if emacs is defined.
19546 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19547 where the include path doesn't have X11/X.h by default. See
19548 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19550 2011-05-20 Kenichi Handa <handa@m17n.org>
19552 * composite.c (find_automatic_composition): Fix previous change.
19554 2011-05-20 Glenn Morris <rgm@gnu.org>
19556 * lisp.mk: New file, split from Makefile.in.
19557 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19558 (shortlisp): Remove.
19559 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19561 2011-05-19 Glenn Morris <rgm@gnu.org>
19563 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19564 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19565 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19566 (lisp): Set the order to that of loadup.el.
19567 (shortlisp): Make it a copy of $lisp.
19568 (SOME_MACHINE_LISP): Remove.
19569 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19570 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19572 2011-05-18 Kenichi Handa <handa@m17n.org>
19574 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19575 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19576 (find_automatic_composition): Mostly rewrite for efficiency.
19578 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19580 * makefile.w32-in: Update dependencies.
19582 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19584 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19585 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19587 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19589 Fix some integer overflow issues, such as string length overflow.
19591 * insdel.c (count_size_as_multibyte): Check for string overflow.
19593 * character.c (lisp_string_width): Check for string overflow.
19594 Use EMACS_INT, not int, for string indexes and lengths; in
19595 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19596 the resulting string length overflows an EMACS_INT; instead,
19597 report a string overflow if no precision given. When checking for
19598 precision exhaustion, use a check that cannot possibly have
19599 integer overflow. (Bug#8675)
19600 * character.h (lisp_string_width): Adjust to new signature.
19602 * alloc.c (string_overflow): New function.
19603 (Fmake_string): Use it. This doesn't change behavior, but saves
19604 a few bytes and will simplify future changes.
19605 * character.c (string_escape_byte8): Likewise.
19606 * lisp.h (string_overflow): New decl.
19608 Fixups, following up to the user-interface timestamp change.
19609 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19610 for UI timestamps, instead of unsigned long.
19611 * msdos.c (mouse_get_pos): Likewise.
19612 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19613 * w32gui.h (Time): Define by including "systime.h" rather than by
19614 declaring it ourselves. (Bug#8664)
19616 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19617 * image.c (clear_image_cache): Likewise.
19619 * term.c (term_mouse_position): Don't assume time_t wraparound.
19621 Be more systematic about user-interface timestamps.
19622 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19623 and sometimes 'EMACS_UINT', to represent these timestamps.
19624 This change causes it to use 'Time' uniformly, as that's what X uses.
19625 This makes the code easier to follow, and makes it easier to catch
19626 integer overflow bugs such as Bug#8664.
19627 * frame.c (Fmouse_position, Fmouse_pixel_position):
19628 Use Time, not unsigned long, for user-interface timestamps.
19629 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19630 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19631 * keyboard.h (last_event_timestamp): Likewise.
19632 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19633 * menu.h (xmenu_show): Likewise.
19634 * term.c (term_mouse_position): Likewise.
19635 * termhooks.h (struct input_event.timestamp): Likewise.
19636 (struct terminal.mouse_position_hook): Likewise.
19637 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19638 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19639 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19640 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19641 what it was before.
19642 * menu.h, termhooks.h: Include "systime.h", for Time.
19644 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19645 Don't assume that the difference between two unsigned long values
19646 can fit into an integer. At this point, we know button_down_time
19647 <= event->timestamp, so the difference must be nonnegative, so
19648 there's no need to cast the result if double-click-time is
19649 nonnegative, as it should be; check that it's nonnegative, just in
19650 case. This bug is triggered when events are more than 2**31 ms
19651 apart (about 25 days). (Bug#8664)
19653 * xselect.c (last_event_timestamp): Remove duplicate decl.
19654 (x_own_selection): Remove needless cast to unsigned long.
19656 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19657 that always fit in int. Use a sentinel instead of a counter, to
19658 avoid a temp and to allay GCC's concerns about possible int overflow.
19659 * frame.h (struct frame): Use int for menu_bar_items_used
19660 instead of EMACS_INT, since it always fits in int.
19662 * menu.c (grow_menu_items): Check for int overflow.
19664 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19666 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19667 Before, the code was not consistent. These values cannot exceed
19668 2**31 - 1 so there's no need to make them unsigned.
19669 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19670 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19671 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19673 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19675 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19676 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19677 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19678 presumably because the widths might not match.
19680 * window.c (size_window): Avoid needless test at loop start.
19682 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19684 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19686 2011-05-12 Drew Adams <drew.adams@oracle.com>
19688 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19690 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19692 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19693 `width' to `bar_area_x' and `bar_area_width', respectively.
19694 (x_scroll_run): Take account of fringe background extension.
19696 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19697 Rename local vars `left' and `width' to `bar_area_x' and
19698 `bar_area_width', respectively.
19699 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19700 background extension.
19702 2011-05-10 Jim Meyering <meyering@redhat.com>
19704 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19706 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19708 * image.c (Finit_image_library): Return t for built-in image types,
19709 like pbm and xbm. (Bug#8640)
19711 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19713 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19715 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19717 * w32console.c (Fset_screen_color): Doc fix.
19718 (Fget_screen_color): New function.
19719 (syms_of_ntterm): Defsubr it.
19721 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19722 unlink the temporary file if Fcall_process didn't create it in the
19724 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19725 child process will be redirected to a file specified with `:file'.
19726 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19727 cue to call_process_cleanup not to close that handle.
19729 2011-05-07 Ben Key <bkey76@gmail.com>
19731 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19732 one of two shell specific rules, either bootstrap-temacs-CMD or
19733 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19734 to the previous implementation of the bootstrap-temacs rule.
19735 The bootstrap-temacs-CMD rule is similar to the previous
19736 implementation of the bootstrap-temacs rule except that it
19737 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19740 These changes, along with some changes to nt/configure.bat,
19741 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19742 earlier fix to add support for --cflags and --ldflags options
19743 that include quotes so that it works whether make uses cmd or
19746 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19748 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19749 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19751 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19752 a string. Handle both cases.
19753 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19754 (Fdbus_register_method): Use Qinvalid_function.
19756 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19758 * makefile.w32-in: Update dependencies.
19759 (LISP_H): Add inttypes.h and stdin.h.
19760 (PROCESS_H): Add unistd.h.
19762 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19764 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19765 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19767 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19769 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19771 * term.c (vfatal): Remove stray call to va_end.
19772 It's not needed and the C Standard doesn't allow it here anyway.
19774 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19775 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19777 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19780 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19782 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19784 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19786 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19788 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19790 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19791 * charset.c (Fdefine_charset_internal): Don't initialize
19792 charset.code_space[15]. The value was garbage, on hosts with
19793 32-bit int (Bug#8600).
19795 * lread.c (read_integer): Be more consistent with string-to-number.
19796 Use string_to_number to do the actual conversion; this avoids
19797 rounding errors and fixes some other screwups. Without this fix,
19798 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19799 (digit_to_number): Move earlier, for benefit of read_integer.
19800 Return -1 if the digit is out of range for the base, -2 if it is
19801 not a digit in any supported base. (Bug#8602)
19803 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19805 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19806 to match comment at start of function. This also removes a
19807 GCC warning about overflow in a 32+64-bit port.
19809 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19811 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19812 Reported by Stefan Monnier in
19813 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19814 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19815 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19817 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19818 (EMACS_UINTPTR): Likewise, with uintptr_t.
19820 * lisp.h: Prefer 64-bit EMACS_INT if available.
19821 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19822 on 32-bit hosts that have 64-bit int, so that they can access
19824 However, temporarily disable this change unless the temporary
19825 symbol WIDE_EMACS_INT is defined.
19827 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19829 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19830 This removes an assumption that EMACS_INT and long are the same
19831 width as pointers. The assumption is true for Emacs porting targets
19832 now, but we want to make other targets possible.
19833 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19834 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19835 In the rest of the code, change types of integers that hold casted
19836 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19837 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19838 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19839 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19840 No need to cast type when ORing.
19841 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19842 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19843 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19844 assume EMACS_INT is the same width as char *.
19845 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19846 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19847 Remove no-longer-needed casts.
19848 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19849 (xg_tool_bar_help_callback, xg_make_tool_item):
19850 Use EMACS_INTPTR to hold an integer
19851 that will be cast to void *; this can avoid a GCC warning
19852 if EMACS_INT is not the same width as void *.
19853 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19854 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19855 (current_message_1, set_message_1):
19856 Use a local to convert to proper width without a cast.
19857 * xmenu.c (dialog_selection_callback): Likewise.
19859 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19860 Also, don't assume VALBITS / RAND_BITS is less than 5,
19861 and don't rely on undefined behavior when shifting a 1 left into
19863 * lisp.h (get_random): Change signature to match.
19865 * lread.c (hash_string): Use size_t, not int, for hash computation.
19866 Normally we prefer signed values; but hashing is special, because
19867 it's better to use unsigned division on hash table sizes so that
19868 the remainder is nonnegative. Also, size_t is the natural width
19869 for hashing into memory. The previous code used 'int', which doesn't
19870 retain enough info to hash well into very large tables.
19871 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19873 * dbusbind.c: Don't possibly lose pointer info when converting.
19874 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19875 Use XPNTR rather than XHASH, so that the high-order bits of
19876 the pointer aren't lost when converting through void *.
19878 * eval.c (Fautoload): Don't double-shift a pointer.
19880 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19882 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19884 * gnutls.c (DEF_GNUTLS_FN):
19885 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19887 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19889 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19892 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19894 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19895 New version that can reserve upto 2GB of heap space.
19897 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19899 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
19901 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
19903 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
19904 `gnutls_certificate_set_x509_key_file'.
19906 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
19908 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
19909 Update dependencies.
19911 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19913 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
19914 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19915 Remove unused parameter `fildes'.
19916 * process.c (read_process_output, send_process): Don't pass it.
19918 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19920 Fix previous change: the library cache is defined in w32.c.
19921 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19922 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
19924 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19926 Implement dynamic loading of GnuTLS on Windows.
19928 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
19929 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
19930 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19933 * gnutls.c (Qgnutls_dll): Define.
19934 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
19935 (gnutls_*): Declare function pointers.
19936 (init_gnutls_functions): New function to initialize function pointers.
19937 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
19938 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
19939 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19940 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
19941 (emacs_gnutls_write, emacs_gnutls_read)
19942 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
19943 (Fgnutls_available_p): New function.
19944 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
19945 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.

20048 produced by %s or %c overflows available buffer space. (Bug#8545)
20050 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20052 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

20055 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20057 * w32.c (init_environment): Warn about defaulting HOME to C:\.

20061 * keyboard.c (Qdelayed_warnings_hook): Define.
20062 (command_loop_1): Run `delayed-warnings-hook'
20063 if Vdelayed_warnings_list is non-nil.
20064 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
20065 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
20067 2011-04-28 Eli Zaretskii <eliz@gnu.org>
20069 * doprnt.c (doprnt): Don't return value smaller than the buffer
20070 size if the message was truncated. (Bug#8545).

20087 Improve `doprnt' and its usage. (Bug#8545)
20088 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20089 `format_end'. Remove support for %l as a conversion specifier.
20090 Don't use xrealloc. Improve diagnostics when the %l size modifier
20091 is used. Update the commentary.
20093 * eval.c (verror): Simplify calculation of size_t.
20095 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20098 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20100 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20103 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20105 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20106 This makes this file independent of the recent pseudovector change.
20108 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20110 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20112 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20113 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20114 Remove unused local.
20115 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20117 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20118 GCC 4.6.0 optimizes based on type-based alias analysis.
20119 For example, if b is of type struct buffer * and v of type struct
20120 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20121 != &v->size, and therefore "v->size = 1; b->size = 2; return
20122 v->size;" must therefore return 1. This assumption is incorrect
20123 for Emacs, since it type-puns struct Lisp_Vector * with many other
20124 types. To fix this problem, this patch adds a new type struct
20125 vectorlike_header that documents the constraints on layout of vectors
20126 and pseudovectors, and helps optimizing compilers not get fooled
20127 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20128 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20129 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20131 (XSETPVECTYPE): Rewrite in terms of new macro.
20132 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20133 This is a bit clearer, and further avoids the possibility of
20134 undesirable aliasing.
20135 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20136 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20137 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20138 since Lisp_Subr is a special case (no "next" field).
20139 (ASIZE): Now uses header.size rather than size.
20140 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20141 to avoid the hassle of writing XVECTOR (foo)->header.size.
20142 (struct vectorlike_header): New type.
20143 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20144 object, to help avoid aliasing.
20145 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20146 (SUBRP): Likewise, since Lisp_Subr is a special case.
20147 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20148 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20149 (struct Lisp_Hash_Table): Combine first two members into a single
20150 struct vectorlike_header member. All uses of "size" and "next" members
20151 changed to be "header.size" and "header.next".
20152 * buffer.h (struct buffer): Likewise.
20153 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20154 * frame.h (struct frame): Likewise.
20155 * process.h (struct Lisp_Process): Likewise.
20156 * termhooks.h (struct terminal): Likewise.
20157 * window.c (struct save_window_data, struct saved_window): Likewise.
20158 * window.h (struct window): Likewise.
20159 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20160 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20161 * buffer.c (init_buffer_once): Likewise.
20162 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20164 * process.c (Fformat_network_address): Use local var for size,
20167 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20169 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20170 * data.c (atof): Remove decl; no longer used or needed.
20171 (digit_to_number): Move to lread.c.
20172 (Fstring_to_number): Use new string_to_number function, to be
20173 consistent with how the Lisp reader treats infinities and NaNs.
20174 Do not assume that floating-point numbers represent EMACS_INT
20175 without losing information; this is not true on most 64-bit hosts.
20176 Avoid double-rounding errors, by insisting on integers when
20177 parsing non-base-10 numbers, as the documentation specifies.
20178 * lisp.h (string_to_number): New decl, replacing ...
20179 (isfloat_string): Remove.
20180 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20181 (read1): Do not accept +. and -. as integers; this
20182 appears to have been a coding error. Similarly, do not accept
20183 strings like +-1e0 as floating point numbers. Do not report
20184 overflow for integer overflows unless the base is not 10 which
20185 means we have no simple and reliable way to continue.
20186 Break out the floating-point parsing into a new
20187 function string_to_number, so that Fstring_to_number parses
20188 floating point numbers consistently with the Lisp reader.
20189 (digit_to_number): Move here from data.c. Make it static inline.
20190 (E_CHAR, EXP_INT): Remove, replacing with ...
20191 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20192 (string_to_number): New function, replacing isfloat_string.
20193 This function checks for valid syntax and produces the resulting
20194 Lisp float number too. Rework it so that string-to-number
20195 no longer mishandles examples like "1.0e+". Use strtoumax,
20196 so that overflow for non-base-10 numbers is reported only when
20197 there's no portable and simple way to convert to floating point.
20199 * textprop.c (set_text_properties_1): Rewrite for clarity,
20200 and to avoid GCC warning about integer overflow.
20202 * intervals.h (struct interval): Use EMACS_INT for members
20203 where EMACS_UINT might cause problems. See
20204 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20205 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20206 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20208 (offset_intervals): Tell GCC not to worry about length overflow
20209 when negating a negative length.
20211 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20212 (overrun_check_free): Likewise.
20214 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20215 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20218 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20219 (gnutls_make_error): Rename local to avoid shadowing.
20220 (gnutls_emacs_global_deinit): ifdef out; not used.
20221 (Fgnutls_boot): Use const for pointer to readonly storage.
20222 Comment out unused local. Fix pointer signedness problems.
20224 * lread.c (openp): Don't stuff size_t into an 'int'.
20225 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20226 about possible signed overflow.
20228 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20229 (GDK_KEY_g): Don't define if already defined.
20230 (xg_prepare_tooltip): Avoid pointer signedness problem.
20231 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20233 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20234 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20236 * xfns.c (Fx_window_property): Simplify a bit,
20237 to make a bit faster and to avoid GCC 4.6.0 warning.
20238 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20240 * fns.c (internal_equal): Don't assume size_t fits in int.
20242 * alloc.c (compact_small_strings): Tighten assertion a little.
20244 Replace pEd with more-general pI, and fix some printf arg casts.
20245 * lisp.h (pI): New macro, generalizing old pEd macro to other
20246 conversion specifiers. For example, use "...%"pI"d..." rather
20247 than "...%"pEd"...".
20248 (pEd): Remove. All uses replaced with similar uses of pI.
20249 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20250 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20251 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20252 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20253 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20254 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20255 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20257 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20258 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20259 * print.c (safe_debug_print, print_object): Likewise.
20260 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20262 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20263 avoiding the 0 flag, which is not portable.
20264 * process.c (Fmake_network_process): Use pI to avoid cast.
20265 * region-cache.c (pp_cache): Likewise.
20266 * xdisp.c (decode_mode_spec): Likewise.
20267 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
20268 behavior on 64-bit hosts with printf arg.
20269 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
20270 (x_stop_queuing_selection_requests): Likewise.
20271 (x_get_window_property): Don't truncate byte count to an 'int'
20274 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20275 here, since it parses constructs like leading '-' and spaces,
20276 which are not wanted; and it overflows with large numbers.
20277 Instead, simply match F[0-9]+, which is what is wanted anyway.
20279 * alloc.c: Remove unportable assumptions about struct layout.
20280 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20281 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20282 (allocate_vectorlike, make_pure_vector): Use the new macros,
20283 plus offsetof, to remove unportable assumptions about struct layout.
20284 These assumptions hold on all porting targets that I know of, but
20285 they are not guaranteed, they're easy to remove, and removing them
20286 makes further changes easier.
20288 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20289 This doesn't fix a bug but makes the code clearer.
20290 (string_overrun_cookie): Now const. Use initializers that
20291 don't formally overflow signed char, to avoid warnings.
20292 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20293 can cause Emacs to crash when string overrun checking is enabled.
20294 (allocate_buffer): Don't assume sizeof (struct buffer) is a
20295 multiple of sizeof (EMACS_INT); it need not be, if
20296 alignof(EMACS_INT) < sizeof (EMACS_INT).
20297 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
20299 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

20314 (handle_user_signal): Break into debugger when debug-on-event
20315 matches the current signal symbol.
20317 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
20319 * alloc.c (check_sblock, check_string_bytes)
20320 (check_string_free_list): Convert to standard C.
20322 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
20324 * w32.c (emacs_gnutls_push): Fix typo.
20326 2011-04-25 Eli Zaretskii <eliz@gnu.org>
20328 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
20329 "cast to pointer from integer of different size".
20331 Improve doprnt and its use in verror. (Bug#8545)
20332 * doprnt.c (doprnt): Document the set of format control sequences
20333 supported by the function. Use SAFE_ALLOCA instead of always
20336 * eval.c (verror): Don't limit the buffer size at size_max-1, that
20337 is one byte too soon. Don't use xrealloc; instead xfree and
20340 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
20342 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
20345 * gnutls.c: Renamed global_initialized to
20346 gnutls_global_initialized. Added internals for the
20347 :verify-hostname-error, :verify-error, and :verify-flags
20348 parameters of `gnutls-boot' and documented those parameters in the
20349 docstring. Start callback support.
20350 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
20351 unless a fatal error occurred. Call gnutls_alert_send_appropriate
20352 on error. Return error code.
20353 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
20354 (emacs_gnutls_read): Likewise.
20355 (Fgnutls_boot): Return handshake error code.
20356 (emacs_gnutls_handle_error): New function.
20357 (wsaerror_to_errno): Likewise.

20362 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
20363 (emacs_gnutls_push): Likewise.
20365 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
20367 * process.c (wait_reading_process_output): Check if GnuTLS
20368 buffered some data internally if no FDs are set for TLS
20371 * makefile.w32-in (OBJ2): Add gnutls.$(O).
20372 (LIBS): Link to USER_LIBS.

20680 * process.c (send_process): Adjust to the new signatures of
20681 emacs_write and emacs_gnutls_write. Do not attempt to store

20874 * font.c (font_close_object): Now static.
20875 * font.h (font_close_object): Remove.
20876 * fontset.c (FONTSET_OBJLIST): Remove.

20879 * fontset.h (face_suitable_for_char_p): Remove decl.
20880 * xfaces.c (face_at_string_position):
20881 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
20882 since 0 is always ASCII.
20884 * fns.c (weak_hash_tables): Now static.

21024 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.

21028 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
21030 alloc.c: Import and export fewer symbols, and remove unused items.
21031 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
21033 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
21034 it's not optimized away by whole-program optimization.

21048 * xdisp.c (message_enable_multibyte): Now static.
21050 Declare Lisp_Object Q* variables to be 'static' if not exported.
21051 This makes it easier for human readers (and static analyzers)
21052 to see whether these variables are used from other modules.
21053 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

21064 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
21066 * lisp.h (DEFINE_FUNC): Make sname 'static'.
21068 Make Emacs functions such as Fatom 'static' by default.
21069 This makes it easier for human readers (and static analyzers)
21070 to see whether these functions can be called from other modules.
21071 DEFUN now defines a static function. To make the function external
21072 so that it can be used in other C modules, use the new macro DEFUE.

21078 Remove decls, since these functions are now static.
21079 (Funintern, Fget_internal_run_time): New decls, since these functions
21080 were already external.
21082 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

21090 Mark functions with DEFUE instead of DEFUN,
21091 if they are used in other modules.
21092 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
21093 decls for now-static functions.
21094 * buffer.h (Fdelete_overlay): Remove decl.

21125 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
21127 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
21130 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21132 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21133 when at ZV. (Bug#8487)
21135 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
21137 * charset.c (Fclear_charset_maps): Use xfree instead of free.

21145 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21146 (overrun_check_free): Protoize.
21148 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21150 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21151 since callers should never pass a negative size.
21152 Change the signature to match that of plain 'read' and 'write'; see
21153 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21154 * lisp.h: Update prototypes of emacs_write and emacs_read.
21156 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21158 * xdisp.c (redisplay_window): Don't try to determine the character
21159 position of the scroll margin if the window start point w->startp
21160 is outside the buffer's accessible region. (Bug#8468)
21162 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21164 Fix write-region and its subroutines for buffers > 2GB.
21165 * fileio.c (a_write, e_write): Modify declaration of arguments and
21166 local variables to support buffers larger than 2GB.
21167 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21169 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21170 argument, local variables, and return value.
21172 * lisp.h: Update prototypes of emacs_write and emacs_read.
21174 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21176 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21178 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21180 Fix more problems found by GCC 4.6.0's static checks.
21182 * xdisp.c (vmessage): Use a better test for character truncation.
21184 * charset.c (load_charset_map): <, not <=, for optimization,
21185 and to avoid potential problems with integer overflow.
21186 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21187 * casetab.c (set_identity, shuffle): Likewise.
21188 * editfns.c (Fformat): Likewise.
21189 * syntax.c (skip_chars): Likewise.
21191 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21192 This also lets GCC 4.6.0 generate slightly better loop code.
21194 * callint.c (Fcall_interactively): <, not <=, for optimization.
21195 (Fcall_interactively): Count the number of arguments produced,
21196 not the number of arguments given. This is simpler and lets GCC
21197 4.6.0 generate slightly better code.
21199 * ftfont.c: Distingish more carefully between FcChar8 and char.
21200 The previous code passed unsigned char * to a functions like
21201 strlen and xstrcasecmp that expect char *, which does not
21202 conform to the C standard.
21203 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21204 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21205 char * when the C standard requires it.
21207 * keyboard.c (read_char): Remove unused var.
21209 * eval.c: Port to Windows vsnprintf (Bug#8435).
21210 Include <limits.h>.
21211 (SIZE_MAX): Define if the headers do not.
21212 (verror): Do not give up if vsnprintf returns a negative count.
21213 Instead, grow the buffer. This ports to Windows vsnprintf, which
21214 does not conform to C99. Problem reported by Eli Zaretskii.
21215 Also, simplify the allocation scheme, by avoiding the need for
21216 calling realloc, and removing the ALLOCATED variable.
21218 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21220 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21221 But keep the doprint source code for now, as we might revamp it
21222 and use it again (Bug#8435).
21223 * lisp.h (doprnt): Remove.
21224 * Makefile.in (base_obj): Remove doprnt.o.
21225 * deps.mk (doprnt.o): Remove.
21227 error: Print 32- and 64-bit integers portably (Bug#8435).
21228 Without this change, on typical 64-bit hosts error ("...%d...", N)
21229 was used to print both 32- and 64-bit integers N, which relied on
21230 undefined behavior.
21231 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21232 * lisp.h (error, verror): Mark as printf-like functions.
21233 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21234 Report overflow in size calculations when allocating printf buffer.
21235 Do not truncate output string at its first null byte.
21236 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21237 Truncate the output at a character boundary, since vsnprintf does not
21239 * charset.c (check_iso_charset_parameter): Convert internal
21240 character to string before calling 'error', since %c now has the
21242 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21243 overflow when computing char to be passed to 'error'. Do not
21244 pass Lisp_Object to 'error'; pass the integer instead.
21245 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21246 formatted with plain %d.
21248 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21250 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
21252 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
21254 * xterm.c (x_catch_errors): Remove duplicate declaration.

21262 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
21263 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
21264 return ssize_t not "int", and use size_t as the buffer length.
21265 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
21266 * gnutls.h: Update declarations.
21267 * process.c (read_process_output): Use ssize_t, to match.
21268 (send_process): Likewise.
21270 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21272 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
21274 2011-04-09 Chong Yidong <cyd@stupidchicken.com>

21277 Use unsigned char, to match FcChar8 type definition.
21279 * xterm.c (handle_one_xevent):
21280 * xmenu.c (create_and_show_popup_menu):
21281 * xselect.c (x_decline_selection_request)
21282 (x_reply_selection_request): Avoid type-punned deref of X events.
21284 2011-04-09 Eli Zaretskii <eliz@gnu.org>
21286 Fix some uses of `int' instead of EMACS_INT.
21287 * search.c (string_match_1, fast_string_match)
21288 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
21289 (scan_buffer, find_next_newline_no_quit)

21293 * xdisp.c (display_count_lines): 3rd argument and return value now
21294 EMACS_INT. All callers changed.
21295 (pint2hrstr): Last argument is now EMACS_INT.

21383 This avoids several warnings with gcc -Wstrict-overflow.
21384 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21385 directly, rather than having caller test rule sign. This avoids
21386 some unnecessary tests.
21387 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21388 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21389 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21391 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21392 (xfont_open): Avoid unnecessary tests.
21394 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21396 * composite.h, composite.c (composition_gstring_put_cache):
21397 Use EMACS_INT, not int, for length.
21399 * composite.h (COMPOSITION_DECODE_REFS): New macro,
21400 breaking out part of COMPOSITION_DECODE_RULE.
21401 (COMPOSITION_DECODE_RULE): Use it.
21402 * composite.c (get_composition_id): Remove unused local vars,
21403 by using the new macro.
21405 * textprop.c (set_text_properties_1): Change while to do-while,
21406 since the condition is always true at first.
21408 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21409 (interval_deletion_adjustment): Return unsigned value.
21412 * process.c (list_processes_1, create_pty, read_process_output):

21428 * print.c (print_error_message): Avoid int overflow.
21430 * font.c (font_list_entities): Redo for clarity,
21431 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21433 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21434 (font_score): Avoid potential overflow in diff calculation.

21437 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21439 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21441 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21442 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21443 can always succeed if overflow has undefined behavior.
21445 * search.c (boyer_moore, wordify): Remove vars set but not used.
21446 (wordify): Omit three unnecessary tests.
21448 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

21453 * dired.c (file_name_completion): Remove var that is set but not used.
21455 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
21457 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21458 (Finsert_file_contents): Remove unnecessary code checking fd.
21460 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21461 Check for integer overflow on size calculations.
21463 * buffer.c (Fprevious_overlay_change): Remove var that is set
21466 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21467 Remove vars that are set but not used.
21468 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21469 (timer_check_2): Mark vars as initialized.
21471 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21473 * image.c (lookup_image): Remove var that is set but not used.
21474 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21476 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21477 that are set but not used.
21479 * xfns.c (make_invisible_cursor): Don't return garbage
21480 if XCreateBitmapFromData fails (Bug#8410).
21482 * xselect.c (x_get_local_selection, x_handle_property_notify):
21483 Remove vars that are set but not used.
21485 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
21486 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
21488 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
21489 Remove var that is set but not used.
21490 (scroll_bar_windows_size): Now size_t, not int.
21491 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21492 Check for overflow.
21494 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21495 (map_tty_color) [!defined MSDOS]: Likewise.
21497 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21499 * coding.c: Remove vars that are set but not used.
21500 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
21501 All callers changed.
21502 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
21503 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21504 (decode_coding_charset): Remove vars that are set but not used.
21506 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21507 that is set but not used.
21509 * print.c (print_object): Remove var that is set but not used.
21511 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21512 The gnulib version avoids calling malloc in the usual case,
21513 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21514 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21515 * filelock.c (current_lock_owner): Likewise.
21516 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21517 * sysdep.c: Include allocator.h, careadlinkat.h.
21518 (emacs_no_realloc_allocator): New static constant.
21519 (emacs_readlink): New function.
21520 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21521 ../lib/careadlinkat.h.
21523 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21525 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21526 first non-nil return value).

21530 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
21531 if not defined (Bug#8403).

21540 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
21541 and thereabouts. All callers changed.
21542 (get_per_char_metric): Remove parameter `f', unused since
21543 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
21545 2011-04-02 Jim Meyering <meyering@redhat.com>
21547 do not dereference NULL upon failed strdup
21548 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21549 (ns_get_family): Likewise.
21551 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21553 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21555 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21557 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21560 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21562 Add lexical binding.
21564 * window.c (Ftemp_output_buffer_show): New fun.
21565 (Fsave_window_excursion):
21566 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
21568 * lread.c (lisp_file_lexically_bound_p): New function.
21569 (Fload): Bind Qlexical_binding.
21570 (readevalloop): Remove `evalfun' arg.
21571 Bind Qinternal_interpreter_environment.
21572 (Feval_buffer): Bind Qlexical_binding.
21573 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21575 (syms_of_lread): Declare `lexical-binding'.
21577 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21579 * keyboard.c (eval_dyn): New fun.
21580 (menu_item_eval_property): Use it.
21582 * image.c (parse_image_spec): Use Ffunctionp.
21584 * fns.c (concat, mapcar1): Accept byte-code-functions.
21586 * eval.c (Fsetq): Handle lexical vars.
21587 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21588 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21589 (FletX, Flet): Obey lexical binding.
21590 (Fcommandp): Handle closures.
21591 (Feval): New `lexical' arg.
21592 (eval_sub): New function extracted from Feval. Use it almost
21593 everywhere where Feval was used. Look up vars in lexical env.
21595 (Ffunctionp): Move from subr.el.
21596 (Ffuncall): Handle closures.
21597 (apply_lambda): Remove `eval_flags'.
21598 (funcall_lambda): Handle closures and new byte-code-functions.
21599 (Fspecial_variable_p): New function.
21600 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21601 but without exporting it to Lisp.
21603 * doc.c (Fdocumentation, store_function_docstring):
21604 * data.c (Finteractive_form): Handle closures.
21606 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21609 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21611 (exec_byte_code): New function extracted from Fbyte_code to handle new
21612 calling convention for byte-code-functions. Add new byte-codes.
21614 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21616 * alloc.c (Fmake_symbol): Init new `declared_special' field.

21620 * xdisp.c (redisplay_internal): Fix prototype.
21622 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21624 * xdisp.c (SCROLL_LIMIT): New macro.
21625 (try_scrolling): Use it when setting scroll_limit.
21626 Limit scrolling to 100 screen lines.
21627 (redisplay_window): Even when falling back on "recentering",
21628 position point in the window according to scroll-conservatively,
21629 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21631 (try_scrolling): When point is above the window, allow searching
21632 as far as scroll_max, or one screenful, to compute vertical
21633 distance from PT to the scroll margin position. This prevents
21634 try_scrolling from unnecessarily failing when
21635 scroll-conservatively is set to a value slightly larger than the
21636 window height. Clean up the case of PT below the margin at bottom
21637 of window: scroll_max can no longer be INT_MAX. When aggressive
21638 scrolling is in use, don't let point enter the opposite scroll
21639 margin as result of the scroll.
21640 (syms_of_xdisp) <scroll-conservatively>: Document the
21641 threshold of 100 lines for never-recentering scrolling.
21643 2011-03-31 Juanma Barranquero <lekktu@gmail.com>

21648 (message_log_check_duplicate): Remove parameters `prev_bol' and
21649 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21650 (redisplay_internal): Remove parameter `preserve_echo_area',
21651 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21653 * indent.c (Fvertical_motion):
21654 * window.c (window_scroll_pixel_based, Frecenter):
21655 Don't pass `need_y_p' to `move_it_by_lines'.
21657 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21659 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21660 steal a few bits to be more compact.
21661 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21662 Remove unneeded casts.
21664 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21666 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21668 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21669 binding" message (bug#7967).
21671 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21673 Fix more problems found by GCC 4.6.0's static checks.
21675 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21676 Remove unused local var.
21678 * editfns.c (Fmessage_box): Remove unused local var.
21680 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21681 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21682 Omit unused local vars.
21683 * window.c (shrink_windows): Omit unused local var.
21684 * menu.c (digest_single_submenu): Omit unused local var.
21685 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21686 Omit unused local var.
21688 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21689 Don't assume string length fits in int.
21690 (keyremap_step, read_key_sequence): Use size_t for sizes.
21691 (read_key_sequence): Don't check last_real_key_start redundantly.
21693 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21694 instead of alloca (Bug#8344).
21696 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21697 (Fbacktrace_frame): Don't assume nframes fits in int.
21699 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21701 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21704 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21706 * cm.c (calccost): Turn while-do into do-while, for clarity.
21708 * keyboard.c (syms_of_keyboard): Use the same style as later
21709 in this function when indexing through an array. This also
21710 works around GCC bug 48267.
21712 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21714 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21716 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21717 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21719 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21720 This avoids undefined behavior on integer overflow, and is a bit
21721 more convenient anyway since it is compared to a size_t variable.
21723 Variadic C functions now count arguments with size_t, not int.
21724 This avoids an unnecessary limitation on 64-bit machines, which
21725 caused (substring ...) to crash on large vectors (Bug#8344).
21726 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21727 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

21734 (funcall_lambda, mark_backtrace): Likewise.
21735 * fns.c (concat): Likewise.
21736 * frame.c (x_set_frame_parameters): Likewise.
21737 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21738 0 if not found, not -1. All callers changed.
21740 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21741 (stack_copy_size): Now size_t, not int.
21742 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

21763 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21764 don't set the hook to nil, but remove the offending function instead.
21765 (Qcommand_hook_internal): Remove, unused.
21766 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21767 Vcommand_hook_internal.

21947 * buffer.c (Fkill_all_local_variables):
21948 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21950 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21951 unconditionally since it does the check itself.
21953 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21955 Fix more problems found by GCC 4.5.2's static checks.
21957 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21958 the first time through the loop, since we know p0 < p1 then.
21959 This also avoids a gcc -Wstrict-overflow warning.
21961 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21962 leading to a memory leak, possible in functions like
21963 load_charset_map_from_file that can allocate an unbounded number
21964 of objects (Bug#8318).
21966 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21967 that could (at least in theory) be that large.
21969 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21970 This is less likely to overflow, and avoids undefined behavior if
21971 overflow does occur. All callers changed. Use strtoul to scan
21972 for the unsigned long integer.
21973 (pint2hrstr): Simplify and tune code slightly.
21974 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

21989 * process.c (Fmake_network_process): Use socklen_t, not int,
21990 where POSIX says socklen_t is required in portable programs.
21991 This fixes a porting bug on hosts like 64-bit HP-UX, where
21992 socklen_t is wider than int (Bug#8277).
21993 (Fmake_network_process, server_accept_connection):
21994 (wait_reading_process_output, read_process_output):
21997 * process.c: Rename or move locals to avoid shadowing.

22007 Make tparam.h and terminfo.c consistent.
22008 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22009 Include tparam.h instead, since it declares them.
22010 * cm.h (PC): Remove extern decl; tparam.h now does this.
22011 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22012 * terminfo.c: Include tparam.h, to check interfaces.
22013 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22014 (tparam): Adjust signature to match interface in tparam.h;
22015 this removes some undefined behavior. Check that outstring and len
22016 are zero, which they always are with Emacs.
22017 * tparam.h (PC, BC, UP): New extern decls.
22019 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22020 (xftfont_open): Rename locals to avoid shadowing.

22034 * composite.c (composition_compute_stop_pos): Rename local to
22036 (composition_reseat_it): Remove unused locals.
22037 (find_automatic_composition, composition_adjust_point): Likewise.
22038 (composition_update_it): Mark var as initialized.
22039 (find_automatic_composition): Mark vars as initialized,
22040 with a FIXME (Bug#8290).
22042 character.h: Rename locals to avoid shadowing.
22043 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
22044 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
22045 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
22046 (BUF_DEC_POS): Be more systematic about renaming local temporaries
22047 to avoid shadowing.
22049 * textprop.c (property_change_between_p): Remove; unused.
22051 * intervals.c (interval_start_pos): Now static.
22053 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

22059 Fix pointer signedness.
22060 (alsa_choose_format): Remove unused local var.
22061 (wav_play): Initialize a variable to 0, to prevent undefined
22062 behavior (Bug#8278).
22064 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22066 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22068 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22069 clobbering (Bug#8298).
22070 * sysdep.c (sys_subshell): Likewise.
22071 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22073 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22074 This should get cleaned up, so that child_setup has the
22075 same signature on all platforms.
22077 * callproc.c (call_process_cleanup): Now static.
22078 (relocate_fd): Rename locals to avoid shadowing.
22080 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
22082 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
22083 not to be necessary, and produces flickering.
22085 2011-03-20 Glenn Morris <rgm@gnu.org>
22087 * config.in: Remove file.
22089 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

22119 (sigchld_handler): Now static.
22121 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
22122 That way, the code declares only the vars that it needs.

22129 * process.c (allocate_pty): Don't declare stb unless it's needed.
22131 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
22132 (CONSTANTLIM): Remove; unused.
22133 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
22134 Define only if needed.
22136 * unexelf.c (unexec): Name an expression,
22137 to avoid gcc -Wbad-function-cast warning.
22138 Use a different way to cause a compilation error if anyone uses
22139 n rather than nn, a way that does not involve shadowing.
22140 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
22142 * deps.mk (unexalpha.o): Remove; unused.
22144 New file unexec.h, the (simple) interface for unexec (Bug#8267).
22145 * unexec.h: New file.
22146 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):

22208 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
22209 some of which prompt warnings from gcc -Wbad-function-cast.
22210 (Fformat_time_string, Fencode_time, Finsert_char):

22239 (Fmemory_limit): Cast sbrk's returned value to char *.
22241 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

22244 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
22246 Use functions, not macros, for up- and down-casing (Bug#8254).
22247 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22248 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
22249 to use the following functions instead of these macros.
22250 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
22251 EMACS_INT, since callers assume the returned value fits in int.
22252 (upcase1): Likewise, for UPCASE_TABLE.
22253 (uppercasep, lowercasep, upcase): New static inline functions.
22254 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

22264 (regex_compile, re_match_2_internal): Mark locals as initialized.
22265 (RETALLOC_IF): Define only if needed.
22266 (WORDCHAR_P): Likewise. This one is never needed, but is used
22267 only in a comment talking about a compiler bug, so put inside
22268 the #if 0 of that comment.
22269 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22270 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

22296 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
22297 New macros, so that the caller can use some names other than
22298 gcpro1, gcpro2, etc.
22299 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22301 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22302 argument, for consistency with GCPRO2_VAR, etc: it is now the
22303 prefix of the variable, not the variable itself. All uses
22305 * dired.c (directory_files_internal, file_name_completion):
22306 Rename locals to avoid shadowing.
22308 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22309 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22310 dired.c's scmp function, had undefined behavior.
22311 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22312 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22313 * buffer.h: ... to here, because these macros use current_buffer,
22314 and the new implementation with inline functions needs to have
22315 current_buffer in scope now, rather than later when the macros
22317 (downcase, upcase1): New static inline functions.
22318 (DOWNCASE, UPCASE1): Reimplement using these functions.
22319 This avoids undefined behavior in expressions like
22320 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22321 from race conditions in accessing the global variables
22322 case_temp1 and case_temp2.
22323 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22324 * lisp.h (case_temp1, case_temp2): Remove their decls.
22325 * character.h (ASCII_CHAR_P): Move from here ...
22326 * lisp.h: ... to here, so that the inline functions mentioned
22327 above can use them.

22331 * fileio.c (file_name_as_directory, directory_file_name):

22334 (file_name_as_directory): Use const pointers when appropriate.
22335 (Fexpand_file_name): Likewise. In particular, newdir might
22336 point at constant storage, so make it a const pointer.
22337 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
22338 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22340 (Fset_file_times, Finsert_file_contents, auto_save_error):

22345 to avoid shadowing.
22347 * marker.c (bytepos_to_charpos): Remove; unused.
22349 * lisp.h (verify_bytepos, count_markers): New decls,
22350 so that gcc does not warn that these functions aren't declared.
22352 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22353 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22354 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22355 (copy_text): Remove unused local var.
22357 * filelock.c (within_one_second): Now static.
22358 (lock_file_1): Rename local to avoid shadowing.
22360 * buffer.c (fix_overlays_before): Mark locals as initialized.
22361 (fix_start_end_in_overlays): Likewise. This function should be
22362 simplified by using pointers-to-pointers, but that's a different
22364 (switch_to_buffer_1): Now static.
22365 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22366 (report_overlay_modification): Rename locals to avoid shadowing.

22369 Fix pointer signedness issue.
22370 (sys_subshell): Mark local as volatile if checking for lint,
22371 to suppress a gcc -Wclobbered warning that does not seem to be right.
22372 (MAXPATHLEN): Define only if needed.
22374 * process.c (serial_open, serial_configure): Move decls from here ...
22375 * systty.h: ... to here, so that they can be checked.
22377 * fns.c (get_random, seed_random): Move extern decls from here ...
22378 * lisp.h: ... to here, so that they can be checked.
22380 * sysdep.c (reset_io): Now static.
22381 (wait_for_termination_signal): Remove; unused.
22383 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

22389 (describe_map_tree):
22390 Rename locals to avoid shadowing.

22539 For example, without this patch (encode-time 0 0 0 1 1
22540 1152921504606846976) returns the obviously-bogus value (-948597
22541 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
22542 reports time overflow. See
