14 * window.h (struct window): Replace hchild, vchild and buffer slots
15 with the only contents slot. This is possible because each valid
16 window may have either the child window (in vertical or horizontal
17 combination) or buffer to display (for the leaf window). Using that,
18 a lof of operations to traverse and/or change window hierarchies may
19 be simplified. New member horizontal is used to distinguish between
20 horizontal and vertical combinations of internal windows.

245 'fullscreen' parameter. Always record previous width and height
246 of the frame, except when switching out of maximized modes, so
247 that they could be restored correctly, instead of resetting to the
248 default frame dimensions. Send SC_RESTORE command to the frame,
249 unless we are going to send SC_MAXIMIZE, to restore the frame
250 resize hints in the mouse pointer shown by the window manager.

403 (produce_chars): Call insert_from_gap with the new arg 0.
404 (encode_coding): Likewise.
405 (decode_coding_gap): Control ASCII optimization by the variable

457 activated, call w32fullscreen_hook, to make sure the new frame
458 dimensions are in effect. (Bug#13937)
460 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
462 * xdisp.c (init_iterator): Simplify because both character and byte
463 positions are either specified or -1. Add eassert. Adjust comment.
464 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
465 character and byte positions can be obtained from marker.

484 * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
485 Include <sys/param.h> unconditionally, as that works elsewhere and
486 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
487 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin

573 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
574 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
575 from Elisp via unread-command-events.
577 * keyboard.c (access_keymap_keyremap): Accept nil return value from
578 functions to mean "no change".

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

602 Adjust call to find_newline.
603 * indent.c (vmotion): Adjust calls to find_newline_no_quit.

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

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

723 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
725 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.

727 (get_visually_first_element, move_it_vertically_backward): Ajust users.

731 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
733 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
734 * filelock.c: Include <c-ctype.h>.
735 (MAX_LFINFO): New top-level constant.
736 (lock_info_type): Remove members pid, boot_time. Add members at,
737 dot, colon. Change user member to be the entire buffer, not a
738 pointer. This allows us to handle the case where a foreign
739 pid or boot time exceeds the local range. All uses changed.
740 (LINKS_MIGHT_NOT_WORK): New constant.
741 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
742 (defined_WINDOWSNT): Remove.
743 (MAKE_LOCK_NAME, file_in_lock_file_name):
744 Always use .#FILE (not .#-FILE) for the file lock,
745 even if it is a regular file.
746 (rename_lock_file): New function.
747 (create_lock_file): Use it.
748 (create_lock_file, read_lock_data):
749 Prefer a symbolic link for the lock file, falling back on a
750 regular file if symlinks don't work. Do not try to create
751 symlinks on MS-Windows, due to security hassles. Stick with
752 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
753 link, rename, unlink, mkstemp) when creating locks, as a GNUish
754 host may be using a Windowsish file system, and cannot use
755 MS-Windows-only system calls. Fall back on mktemp if mkstemp
756 doesn't work. Don't fail merely because of a symlink-contents
757 length limit in the current file system; fall back on regular
758 files. Increase the symlink contents length limit to 8 KiB, this
759 should be big enough for any real use and doesn't crunch the
761 (create_lock_file, lock_file_1, read_lock_data):
762 Simplify allocation of lock file buffers now that they fit in 8 KiB.
763 (lock_file_1): Return error number, not bool. All callers changed.
764 (ELOOP): New macro, if not already defined.
765 (read_lock_data): Return size of lock file contents, not Lisp object.
766 All callers changed. Handle a race condition if some other process
767 replaces a regular-file lock with a symlink lock or vice versa,
768 while we're trying to read the lock.
769 (current_lock_owner): Parse contents more carefully, to help avoid
770 confusing a regular-file lock with some other application's use
771 of the file. Check for lock file contents being too long, or
772 not parsing correctly.
773 (current_lock_owner, lock_file):
774 Allow foreign pid and boot times that exceed the local range.
775 (current_lock_owner, lock_if_free, lock_file):
776 Simplify allocation of lock file contents.
777 * w32.c (sys_rename_replace): New function, containing most of
778 the contents of the old sys_rename.
779 (sys_rename): Use it.
780 (fchmod): New dummy function.
781 * w32.h (sys_rename_replace, fchmod): New decls.
783 2013-03-05 Eli Zaretskii <eliz@gnu.org>
785 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
786 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
787 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
788 <dmantipov@yandex.ru>.
790 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
792 * composite.c (get_composition_id, fill_gstring_header):
793 Use make_uninit_vector where appropriate.
794 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
795 * xselect.c (clean_local_selection_data): Likewise.
797 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
799 Fix misuse of ImageMagick that caused core dump (Bug#13846).
800 * image.c (imagemagick_load_image): Calculate height and width
801 after flattening the image, not before.
803 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
805 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
806 * ftfont.c (ftfont_shape_by_flt): Likewise.
807 * w32uniscribe.c (uniscribe_shape): Likewise.
809 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
811 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
812 The old approach, which fell back on DIR/.#FILE.0 through
813 DIR/.#FILE.9, had race conditions that could not be easily fixed.
814 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
815 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
816 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
817 because the locking mechanism was never reliable in that case).
818 This patch fixes this and other bugs discovered by a code
819 inspection that was prompted by
820 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
821 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
822 to avoid interoperability problems between the MS-Windows and
823 non-MS-Windows implementations. MS-Windows and non-MS-Windows
824 instances of Emacs now ignore each others' locks.
825 * filelock.c (defined_WINDOWSNT): New constant.
826 (MAKE_LOCK_NAME, fill_in_lock_file_name):
827 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
828 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
829 regular files on MS-Windows hosts.
830 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
831 Use SAFE_ALLOCA to avoid problems with long file names.
832 (MAX_LFINFO): Now a local constant, not a global macro.
833 (IS_LOCK_FILE): Remove.
834 (lock_file_1): Don't inspect errno if symlink call succeeds;
836 (lock_file): Document that this function can return if lock
838 (lock_file): Don't access freed storage.
840 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>

844 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
846 * textprop.c: Use bool for booleans.
847 (validate_interval_range, Fadd_text_properties)
848 (Fremove_text_properties): Prefer bool to int when either works.
850 2013-03-02 Eli Zaretskii <eliz@gnu.org>
852 * textprop.c (Fadd_text_properties, Fremove_text_properties):
853 If the interval tree changes as a side effect of calling
854 modify_region, re-do processing starting from the call to
855 validate_interval_range. (Bug#13743)
857 2013-02-28 Eli Zaretskii <eliz@gnu.org>
859 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
862 2013-02-27 Eli Zaretskii <eliz@gnu.org>
864 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
865 _SH_DENYRW flag, instead of emacs_open, to deny any other process
866 access to the lock file until it is written and closed.
869 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
871 * callint.c (Qcall_interactively):
872 * macros.c (Qexecute_kbd_macro):

877 * window.c (Frecenter): Tiny docstring enhancement.
879 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
881 Minor textprop integer cleanup.
882 * intervals.h, textprop.c (add_text_properties_from_list):
883 Return void, not int, since nobody uses the return value.
884 * textprop.c (validate_plist, add_properties, remove_properties)
885 (Fadd_text_properties):
886 Don't assume list length fits in int.
887 (interval_has_all_properties, interval_has_some_properties)
888 (interval_has_some_properties_list, add_properties, remove_properties)
889 (Fadd_text_properties, Fremove_text_properties)
890 (Fremove_list_of_text_properties, text_property_stickiness):
891 Use bool for booleans.
892 (Fadd_text_properties, Fremove_text_properties):
893 (Fremove_list_of_text_properties):
894 Reindent do-while as per GNU style.

898 Implement CLASH_DETECTION for MS-Windows.
900 * filelock.c [WINDOWSNT]: Include w32.h.
901 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
902 function of that name. Up-case the macro arguments.
903 (IS_LOCK_FILE): New macro.
904 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
905 (create_lock_file): New function, with body extracted from
907 [WINDOWSNT]: Implement lock files by writing a regular file with
908 the lock information as its contents.
909 (read_lock_data): New function, on Posix platforms just calls
911 [WINDOWSNT]: Read the lock info from the file.
912 (current_lock_owner): Call read_lock_data instead of calling
913 emacs_readlinkat directly.
914 (lock_file) [WINDOWSNT]: Run the file name through
917 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
918 just check if the process by that PID exists.
920 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
921 also present, as doing so will fail to error out if the file
924 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
926 * textprop.c (Fadd_text_properties, Fremove_text_properties)
927 (Fremove_list_of_text_properties): Skip all of the intervals in
928 the region between START and END that already have resp. don't
929 have the requested properties, not just the first one.
930 Add assertions that the loop afterwards always modifies the
931 properties. (Bug#13743)
933 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>

960 (make_hdr): Use DATA_START instead of start_of_data.
961 * vm-limit.c: Move most of mem-limits.h's contents here.
962 (data_start): New decl. It's OK if this is approximate,
963 so simplify-away some unnecessary exactness.
964 (POINTER): Remove; all uses removed.
965 (data_space_start): Now char *, to avoid casts.
966 (exceeds_lisp_ptr): New function, replacing the old
967 EXCEEDS_LISP_PTR macro. All uses changed.

988 Assume C89 or better.
989 * ralloc.c (SIZE, POINTER, NIL):
990 * vm-limit.c (POINTER):
991 Remove, replacing all uses with C89 equivalents. These old
992 symbols were present only for porting to pre-C89 platforms.
994 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
996 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
997 This avoids warning messages reported as part of Bug#13546.

1012 2013-02-19 Daniel Colascione <dancol@dancol.org>
1014 * sheap.c (report_sheap_usage): Use message, not message1, so
1015 that we don't try to create a buffer while we're in the middle
1016 of dumping Emacs. Explain why.
1018 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
1020 * search.c (find_newline): Return byte position in bytepos.

1036 resources were not orderly released.
1038 2013-02-17 Eli Zaretskii <eliz@gnu.org>
1040 * xdisp.c (x_draw_vertical_border): For a window that is neither

1083 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1085 * keyboard.c (read_char): Fix calculation of auto-save time out
1086 when auto-save-timeout is less than 4. (Bug#13720)
1088 * w32proc.c (new_child): Free up to 2 slots of dead processes at a

1115 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1117 Fix AIX port (Bug#13650).
1118 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
1119 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
1120 was #undeffed earlier, so it cannot be used as a macro here.
1121 Use the constant and not the macro.
1123 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1125 * w32proc.c (new_child): If no vacant slots are found in
1126 child_procs[], make another pass looking for slots whose process
1127 has exited or died. (Bug#13546)
1129 * w32.c (sys_pipe): When failing due to file descriptors above
1130 MAXDESC, set errno to EMFILE.
1131 (_sys_read_ahead): Update cp->status when failing to read serial
1132 communications input, so that the status doesn't stay at
1133 STATUS_READ_IN_PROGRESS. (Bug#13546)
1135 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
1137 * gtkutil.c (tb_size_cb): New function.

1147 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
1149 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>

1159 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
1161 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1163 Improve AIX port some more (Bug#13650).
1164 With this, it should be as good as it was in 23.3, though it's
1165 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
1166 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
1167 * unexaix.c (start_of_text): Remove.
1168 (_data, _text): Declare as char[], not int, as AIX manual suggests.
1169 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
1170 (orig_load_scnptr, orig_data_scnptr):
1171 Now off_t, not long, since they are file offsets.
1172 (make_hdr): Use _data, not start_of_data ().
1173 This is the key part of the fix.
1174 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
1175 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
1177 * pre-crt0.c (data_start): Initialize to 1.
1178 This ports to compilers that optimize the external declaration
1179 'int x = 0;' as if it were 'int x;' to shrink the executable.
1181 Improve AIX port (Bug#13650).
1182 This doesn't fix the bug, but it makes progress: Emacs builds now.
1183 * unexaix.c: Include inttypes.h, stdarg.h.
1184 (report_error, report_error_1): Mark as _Noreturn.
1185 (report_error): Don't report the wrong errno.
1186 (report_error_1): Now varargs. All callers changed.
1187 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
1188 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
1189 (write_ptr): Use %p to print address rather than %lx and a cast
1190 to unsigned long. Grow buffer a bit, to be safer.
1192 2013-02-13 Eli Zaretskii <eliz@gnu.org>
1194 * bidi.c (bidi_resolve_neutral): After finding the next
1195 non-neutral character, accept NEUTRAL_ON type as well, because
1196 directional control characters, such as LRE and RLE, have their
1197 type converted to that by bidi_resolve_weak. This avoids aborts
1198 when LRE/RLE follows a run of neutrals.
1199 (bidi_move_to_visually_next): Assert that return value of
1200 bidi_peek_at_next_level is non-negative. Negative values will
1203 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1205 Minor getenv-related fixes.
1206 * callproc.c (Fcall_process_region) [!DOS_NT]:
1207 Avoid unnecessary duplicate call to getenv.
1208 * callproc.c (init_callproc):
1209 * dispnew.c (init_display):
1210 * sysdep.c (sys_subshell):
1211 Omit unnecessary cast of getenv or egetenv.
1213 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
1215 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
1216 Update dependencies.
1218 2013-02-12 Eli Zaretskii <eliz@gnu.org>
1220 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
1222 (display_line): Set w->region_showing to the value of
1223 it->region_beg_charpos, not to -1. This fixes redisplay
1224 optimization when cursor is moved up after M->. (Bug#13623)
1226 (try_scrolling): Scroll text up more if point is too close to ZV
1227 and inside the scroll margin. This makes sure point is moved
1228 outside the scroll margin in these cases.
1230 * window.h (struct window): region_showing can no longer be
1233 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
1235 Tune by using memchr and memrchr.
1236 * doc.c (Fsnarf_documentation):
1237 * fileio.c (Fsubstitute_in_file_name):
1238 * search.c (find_newline, scan_newline):
1239 * xdisp.c (pos_visible_p, display_count_lines):
1240 Use memchr and memrchr rather than scanning byte-by-byte.
1241 * search.c (find_newline): Rename from scan_buffer.
1242 Omit first arg TARGET, as it's always '\n'. All callers changed.
1244 Clean up read_key_sequence a tiny bit more.
1245 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
1246 (read_key_sequence): Remove unused locals.
1248 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
1250 Clean up read_key_sequence a bit; reread active keymaps after first event.
1251 * keyboard.c (read_char, read_char_x_menu_prompt)
1252 (read_char_minibuf_menu_prompt):
1253 Replace nmaps+maps with a single `map' arg.
1254 (follow_key): Operate on a single map.
1255 (active_maps): New function.
1256 (test_undefined): Also return true for nil bindings.
1257 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
1258 a single (composed) keymap. Remember `first_event' to choose the right
1259 set of active keymaps. Recompute the set of keymaps after receiving
1260 the first event. Remove GOBBLE_FIRST_EVENT.
1261 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
1262 * keyboard.h (read_char): Update declaration.
1263 * lread.c (read_filtered_event): Adjust call to read_char.
1265 2013-02-11 Eli Zaretskii <eliz@gnu.org>
1267 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1268 Don't use the limitation on backwards movement when lines are truncated
1269 in the window. (Bug#13675)
1271 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
1273 * marker.c (set_marker_internal): If desired position is passed
1274 as a marker, avoid call to buf_charpos_to_bytepos.
1275 * window.c (Fset_window_point): Omit redundant type checking.
1276 (Fset_window_start): Likewise. Format comment.
1277 (window_scroll_pixel_based): Use set_marker_restricted_both
1278 with character and byte positions obtained from an iterator.
1279 (Fset_window_configuration): Use set_marker_restricted_both.
1280 * xdisp.c (message_dolog): Likewise.
1282 2013-02-10 Eli Zaretskii <eliz@gnu.org>
1284 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1285 When text lines are longer than window's screen lines, don't move back
1286 too far. This speeds up some redisplay operations. (Bug#13675)
1288 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
1290 * syntax.c (scan_sexps_forward): Fix byte position calculation
1291 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
1293 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
1295 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
1296 that was not needed.
1298 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
1300 Minor hashing refactoring.
1301 * fns.c (SXHASH_REDUCE): Move to lisp.h.
1302 (sxhash_float): Return EMACS_UINT, for consistency with the other
1304 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
1305 non-static inline function and therefore can't use static vars.
1306 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
1307 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
1308 with the other hash functions.
1310 2013-02-09 Eli Zaretskii <eliz@gnu.org>
1312 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
1313 XXXXXX part of the temporary file pattern is not downcased even
1314 when w32-downcase-file-names is non-nil. (Bug#13661)
1316 * xdisp.c (decode_mode_spec): Remove handling of %t.

1405 which still means region is being displayed.
1406 (redisplay_internal): Resurrect code that forced redisplay of the
1407 whole window when showing region and the mark has changed.
1408 Record the new mark position to allow redisplay optimizations.
1409 (display_line): If it->region_beg_charpos is non-zero, set the
1410 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1412 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1413 not bitfield of 1 bit.
1415 2013-02-03 Daniel Colascione <dancol@dancol.org>
1417 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1418 daemon mode works on cygw32 when Emacs is installed and not just
1421 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1423 Avoid file time stamp bug on MS-Windows (Bug#13149).
1424 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1425 as FAT32 doesn't update time stamps when truncating them.
1426 Also, check that a file time stamp is not a multiple of 100 ns;
1427 this should catch all instances of the problem on MS-Windows,
1428 as its native file system resolution is 100 ns or worse, and
1429 checking for a non-multiple of 100 ns should impose only a small
1430 overhead on systems with ns resolution.
1432 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1434 Avoid encoding file names on MS-Windows when they need to be run
1435 through dostounix_filename.
1436 * w32.c (normalize_filename): Accept an additional argument
1437 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1438 downcase it even if w32-downcase-file-names is non-nil.
1439 (dostounix_filename): Accept an additional argument MULTIBYTE and
1440 pass it to normalize_filename.
1441 (emacs_root_dir): Adjust.
1443 * msdos.h (dostounix_filename): Adjust prototype.
1445 * w32.h (dostounix_filename): Adjust prototype.
1447 * msdos.c (dostounix_filename): Accept an additional argument and
1449 (init_environment): Adjust callers of dostounix_filename.
1451 * fileio.c (Ffile_name_directory, file_name_as_directory)
1452 (directory_file_name, Fexpand_file_name)
1453 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1455 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1457 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1458 variables, as egetenv is case-insensitive for DOS_NT.
1460 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1461 with an encoded file name.
1463 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1464 Adjust calls to dostounix_filename.
1466 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1468 * unexw32.c (unexec): Adjust call to dostounix_filename.
1470 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1472 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1475 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1478 * callproc.c (Fcall_process): Make sure program name in PATH and
1479 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1480 is passed to exec/spawnve, which fails unless the file-name
1483 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1484 even if w32-quote-process-args is nil.
1486 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1488 Fix timestamp bug when write-region appends nothing (Bug#13149).
1489 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1490 the file's time stamp doesn't change if Emacs happens to write nothing
1491 to the file, and on a buggy file system this could cause Emacs to
1492 incorrectly infer that the file system doesn't have the bug.
1493 Avoid this problem by inhibiting the inference in this case.
1495 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1497 * window.h (struct window): Convert base_line_number, base_line_pos
1498 and column_number_displayed members from Lisp_Object to ptrdiff_t.
1499 Convert region_showing member from Lisp_Object to bitfield.
1500 Remove sequence_number member. Adjust comments.
1501 * window.c (sequence_number): Remove.
1502 (make_window): Initialize column_number_displayed.
1503 * print.c (print_object): Follow the printed representation of
1504 frames and print window pointer to distinguish between windows.
1505 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
1506 * xdisp.c (wset_base_line_number, wset_base_line_pos)
1507 (wset_column_number_displayed, wset_region_showing): Remove.
1508 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1509 (try_scrolling, try_cursor_movement, redisplay_window)
1510 (try_window_reusing_current_matrix, try_window_id, display_line)
1511 (display_mode_lines, decode_mode_spec): Adjust users.
1512 * .gdbinit (pwinx): Do not print sequence_number.
1514 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1516 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1517 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1518 * dired.c: Include <fcntl.h>.
1519 (open_directory): New function, which uses open and fdopendir
1520 rather than opendir. DOS_NT platforms still use opendir, though.
1521 (directory_files_internal, file_name_completion): Use it.
1522 (file_attributes): New function, with most of the old Ffile_attributes.
1523 (directory_files_internal, Ffile_attributes): Use it.
1524 (file_attributes, file_name_completion_stat): First arg is now fd,
1525 not dir name. All uses changed. Use fstatat rather than lstat +
1527 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1528 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1529 (emacs_readlinkat): New function, with much of the old
1530 Ffile_symlink_p, but with an fd argument for speed.
1531 It uses readlinkat rather than careadlinkatcwd, so that it
1532 need not assume the working directory.
1533 (Ffile_symlink_p): Use it.
1534 * filelock.c (current_lock_owner): Use emacs_readlinkat
1535 rather than emacs_readlink.
1536 * lisp.h (emacs_readlinkat): New decl.
1537 (READLINK_BUFSIZE, emacs_readlink): Remove.
1538 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1539 (emacs_norealloc_allocator, emacs_readlink): Remove.
1540 This stuff is moved to fileio.c.
1541 * w32.c (fstatat, readlinkat): New functions.
1542 (careadlinkat): Don't check that fd == AT_FDCWD.
1543 (careadlinkatcwd): Remove; no longer needed.
1545 2013-01-31 Glenn Morris <rgm@gnu.org>
1547 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
1548 (Fwrite_region): Update for new choose_write_coding_system args.
1549 Move the last piece of choose_write_coding_system here. (Bug#13522)
1550 (syms_of_fileio): Add choose-write-coding-system.
1552 2013-01-30 Eli Zaretskii <eliz@gnu.org>
1554 * w32.c (sys_open): Zero out the flags for the new file descriptor.
1555 (sys_close): Zero out the flags for the file descriptor before
1556 closing it. (Bug#13546)
1558 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1559 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1560 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1563 * w32.c (w32_get_long_filename, init_environment, readlink):
1564 Support file names encoded in DBCS codepages.
1565 (readlink): Use the current file-name-coding-system, not the ANSI
1566 codepage, to decode and handle targets of symlinks.
1568 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1570 * w32.c (opendir): Now accepts a 'const char *'.
1572 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
1574 Remove obsolete redisplay code. See the discussion at
1575 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
1576 * dispnew.c (preemption_period, preemption_next_check): Remove.
1577 (Vredisplay_preemption_period): Likewise.
1578 (update_frame, update_single_window, update_window, update_frame_1):
1579 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
1580 used, following the 2012-06-22 change.
1582 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1584 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1586 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
1588 * font.c (num_fonts): Remove the leftover from old
1589 debugging code. Adjust comment style here and there.
1590 * insdel.c (insert_1): Remove.
1591 * lisp.h (insert_1): Remove prototype.
1592 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
1594 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1596 * w32.c (max_filename_mbslen): New function.
1597 (normalize_filename, readdir): Use it to detect locales where ANSI
1598 encoding of file names uses a double-byte character set (DBCS).
1599 If a DBCS encoding is used, advance by characters using
1600 CharNextExA, instead of incrementing a 'char *' pointer.
1601 Use _mbslwr instead of _strlwr. (Bug#13515)
1603 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1604 request of memory reservation to 1.7GB. (Bug#13065)
1606 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
1608 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
1609 at check_extra_latin label. (Bug#13505)
1611 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1613 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
1614 Avoid redundant calls to strlen.
1616 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1618 Drop async_visible and async_iconified fields of struct frame.
1619 This is possible because async input is gone; for details, see
1620 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1621 * frame.h (struct frame): Remove async_visible and async_iconified
1622 members, convert garbaged to unsigned bitfield. Adjust comments.
1623 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
1624 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
1625 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
1626 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
1627 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
1629 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
1630 properly. Likewise for obscured.
1632 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
1635 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
1637 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1639 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
1640 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1642 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1644 * xdisp.c (message2, message2_nolog): Remove functions.
1645 (message3, message3_nolog): Extract nbytes and multibyteness directly
1646 from the string. Change all callers.
1647 (message3_nolog): Don't set message_enable_multibyte since set_message
1648 will reset it anyway.
1649 (message1, message1_nolog): Use message3.
1650 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1651 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1652 (set_message): Drop all but the second arg, which has to be a string.
1653 (set_message_1): Simplify now that we know that a1 is NULL and the
1654 second arg is a string.
1655 * frame.h (struct frame): Remove `message_buf' field.
1656 Use glyphs_initialized_p instead.
1657 (FRAME_MESSAGE_BUF): Remove macro.
1658 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
1659 * lisp.h (message2, message2_nolog): Remove declarations.
1660 (message3, message3_nolog): Update declarations.
1661 * keyboard.c (read_char_minibuf_menu_text)
1662 (read_char_minibuf_menu_width): Remove vars.
1663 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
1664 to correctly handle multibyte strings.
1665 * frame.c (delete_frame): Don't free message_buf any more.
1666 * editfns.c (message_text, message_length): Remove vars.
1667 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1668 * fileio.c (auto_save_error): Use message3 instead of message2.
1669 * dispnew.c (adjust_frame_message_buffer): Remove function.
1671 2013-01-23 Eli Zaretskii <eliz@gnu.org>
1673 * w32term.c (w32fullscreen_hook): Account correctly for the screen
1674 real estate used for the tool bar and the menu bar.
1676 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
1678 * insdel.c (prepare_to_modify_buffer): Force redisplay if
1679 hidden buffer is prepared to modification (Bug#13164).
1681 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1683 * window.h (struct window): Change window_end_valid member from
1684 Lisp_Object to a bitfield. Adjust comments.
1685 (wset_window_end_valid): Remove.
1686 * window.c (adjust_window_count): Clear window_end_valid.
1687 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
1688 (Fwindow_line_height, set_window_buffer, Frecenter)
1689 (Fsplit_window_internal, Fdelete_other_windows_internal)
1690 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
1691 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
1692 * xdisp.c (check_window_end, reconsider_clip_changes)
1693 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1694 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1695 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1697 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1699 * xdisp.c (mark_window_display_accurate): Simplify the loop
1700 assuming that the only one of vchild, hchild or buffer window
1701 slots is non-nil. Call mark_window_display_accurate_1 for
1702 the leaf windows only.
1703 (mark_window_display_accurate_1): Always assume leaf window.
1706 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1708 * emacs.c (Qkill_emacs_hook): Now static.
1710 * fileio.c (Finsert_file_contents): Simplify.
1711 Remove unnecessary assignments and tests.
1713 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1715 * w32.c (acl_set_file): Don't test for errors unless
1716 set_file_security returns FALSE. Avoids spurious errors when
1719 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1721 * fileio.c (Finsert_file_contents): Revert code introduced at
1722 2013-01-18 in favor of the simpler and generally better fix.
1723 Save stack space by removing 'buffer' and reusing 'read_buf'
1726 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1728 * lisp.h (eabs): Define unconditionally (Bug#13419).
1729 The old "#if !defined (eabs)" was an unnecessary revenant of back
1730 when this macro was called "abs". Document 'eabs' better.
1732 2013-01-19 Glenn Morris <rgm@gnu.org>
1734 * fns.c (Frandom): Doc fix.
1736 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1738 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1739 segfault when there are lots of overlays.
1741 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1742 when there are lots of overlays.
1743 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1744 for the details and a way to reproduce.
1746 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1748 * fileio.c: Use O_APPEND to append.
1749 This corresponds better to the natural interpretation of "append",
1750 and avoids the need to open the output file twice, or to invoke
1751 lseek when APPEND is neither nil nor a number.
1752 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1753 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1754 file possibly twice, and lseeking to its end; this avoids the
1755 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1756 at the same time: the combination is never needed and apparently
1757 it doesn't work with DOS_NT.
1759 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1760 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1762 Allow floating-point file offsets.
1763 Problem reported by Vitalie Spinu in
1764 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1765 * fileio.c (emacs_lseek): Remove.
1766 (file_offset): New function.
1767 (Finsert_file_contents, Fwrite_region): Use it.
1769 2013-01-19 Chong Yidong <cyd@gnu.org>
1771 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1772 aborting on Fsignal (Bug#13289).
1774 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1776 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1777 set_file_security as failure due to insufficient privileges.
1778 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1779 (fstat): Return owner and group like 'stat' and 'lstat' do.
1781 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1783 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1784 The bug was observed on Ubuntu operating inside a virtual machine,
1785 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1786 The workaround introduces a race condition on non-buggy hosts,
1787 but it's an unlikely race and anyway there's a nearly identical
1788 nearby race that can't be fixed.
1789 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1791 (Fwrite_region): Test for file system time stamp bug.
1792 (init_fileio): New function.
1793 * lisp.h (init_fileio): Declare it.
1794 * emacs.c (main): Call it.
1796 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1797 and make it more consistent with other stat-failure diagnostics.
1799 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
1801 Fix crash when inserting data from non-regular files.
1802 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
1803 for the error description produced by valgrind.
1804 * fileio.c (read_non_regular): Rename to read_contents.
1805 Free Lisp_Save_Value object used to pass parameters.
1806 (read_non_regular_quit): Rename to read_contents_quit.
1807 (Finsert_file_contents): Redesign internal file reading loop to adjust
1808 gap and end positions after each read and so help make_gap to work
1809 properly. Do not signal an I/O error too early and so do not leave
1810 not yet decoded characters in a buffer, which was the reason of
1811 redisplay crash. Use list2 to build return value. Adjust comments.
1813 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1815 Close a race when statting and reading files (Bug#13149).
1816 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1817 This avoids a race if the file is renamed between stat and open.
1818 This race is not the problem originally noted in Bug#13149;
1819 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
1821 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
1823 * lisp.h (toplevel): Add comment about using Lisp_Save_Value
1824 objects, related functions and macros.
1825 (make_save_value): Adjust prototype.
1826 (make_save_pointer): New prototype.
1827 (SAFE_NALLOCA): Fix indentation. Use make_save_pointer.
1828 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
1829 * alloc.c (format_save_value): Rename to make_save_value.
1830 (make_save_pointer): New function.
1831 (record_xmalloc): Use make_save_pointer.
1832 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
1833 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
1834 Change users of make_save_value to make_save_pointer.
1835 Likewise for format_save_value and make_save_value.
1837 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
1839 * buffer.h (NARROWED, BUF_NARROWED): Drop unused macros.
1840 (DECODE_POSITION, BUFFER_CHECK_INDIRECTION): Fix indentation.
1841 * buffer.c (toplevel, syms_of_buffer): Drop old commented-out
1844 2013-01-15 Paul Eggert <eggert@cs.ucla.edu>
1846 * alloc.c (free_save_value): Now static.
1848 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1850 * keymap.c (map_keymap_internal): Use format_save_value.
1851 (map_keymap_char_table_item): Adjust accordingly.

1920 (save_excursion_restore): Adjust to match new layout. Use free_misc
1921 because we do not allocate extra memory any more. Add eassert.
1922 * print.c (print_object): New code to print Lisp_Save_Value. Do not
1923 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

1937 Fix SIGDANGER handlers, for AIX (Bug#13408).
1938 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:

1991 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
1993 Avoid unnecessary byte position calculation for the gap movement.

2009 switches from 'signal' to 'pthread_sigmask', which is safer in
2010 multithreaded applications.
2011 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
2012 which has already arranged for that.
2013 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.

2033 left-margin-width, right-margin-width, left-fringe-width,
2034 right-fringe-width, scroll-bar-width and buffer-display-count.
2035 Use Qstringp for default-directory, buffer-file-name,
2036 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
2037 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for

2090 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
2091 Display the newline glyph more unambiguously.
2093 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2095 * nsterm.m (ns_draw_underwave):
2096 * w32term.c (w32_draw_underwave):
2097 * xterm.c (x_draw_underwave): Make underwave look more triangular
2098 and also degrade gracefully for small fonts. (Bug#13000)
2100 * nsterm.m (ns_draw_text_decoration):
2101 * w32term.c (x_draw_glyph_string):
2102 * xterm.c (x_draw_glyph_string): Don't use previous underline
2103 thickness and position if previous underline type is underwave.

2123 * term.c (tty_ins_del_lines):
2124 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
2125 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
2127 2012-12-31 Eli Zaretskii <eliz@gnu.org>
2129 * w32.c (unsetenv): Set up the string passed to _putenv
2131 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
2132 for the bug this caused.
2134 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
2136 * coding.c (Qmac): Now static.
2138 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
2140 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
2141 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

2150 Check toolbar_is_packed.
2151 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
2152 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2153 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
2155 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2156 (xg_update_menubar): Update title only if
2157 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2158 (xg_update_submenu): Skip tearoff only if
2159 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2160 (xg_initialize): Initialize xg_detached_menus only if
2161 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2163 * xterm.h (struct x_output): Surround handlebox_widget with
2164 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
2165 toolbar_in_hbox is bool.
2167 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
2169 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
2170 (LIBS_GNUSTEP): Define.

2174 2012-12-30 Eli Zaretskii <eliz@gnu.org>
2176 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
2177 continuation glyph on a TTY with an indication of an empty line.
2180 2012-12-29 Eli Zaretskii <eliz@gnu.org>
2182 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
2183 file's SELinux context or ACLs successfully set, nil otherwise.
2185 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
2187 * w32proc.c (reader_thread): Avoid passing NULL handles to
2188 SetEvent and WaitForSingleObject.
2190 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
2192 Port EXTERNALLY_VISIBLE to Clang 3.2.
2193 * conf_post.h (__has_attribute): New macro.
2194 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
2196 2012-12-27 Glenn Morris <rgm@gnu.org>
2198 * cygw32.c (Fcygwin_convert_file_name_to_windows)
2199 (Fcygwin_convert_file_name_from_windows): Doc fixes.
2201 2012-12-27 Eli Zaretskii <eliz@gnu.org>
2203 * fileio.c (file_name_as_directory, directory_file_name):
2204 Accept an additional argument MULTIBYTE to indicate whether the input C
2205 came from a multibyte or a unibyte Lisp string; all callers
2206 adjusted. Don't assume the input string is always multibyte.
2208 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
2209 don't ENCODE_FILE them, and return a unibyte string if the input
2211 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
2212 don't assume the input strings will always be multibyte. If the
2213 input strings are multibyte, decode strings obtained from C
2216 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2218 * lisp.h (toplevel): Add two notices to the comment about
2219 defining a new Lisp data type.

2223 * alloc.c (valid_lisp_object_p): Adjust comment.
2225 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2227 * keyboard.c (record_asynch_buffer_change): Initialize an event
2228 only if it's really needed.
2229 * frame.h (enum output_method): Remove output_mac member since
2230 it's a leftover from the deleted code.
2231 * frame.c (Fframep): Adjust user here ...
2232 * terminal.c (Fterminal_live_p): ... and here.
2233 * coding.c (Qmac): Now here because it's only used to denote
2234 end-of-line encoding type.
2235 (syms_of_coding): DEFSYM it.
2236 * frame.h (Qmac): Remove duplicated declaration.
2238 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
2240 * window.c (select_window_1): Now static, since it's used only here.
2242 2012-12-25 Eli Zaretskii <eliz@gnu.org>
2244 * window.c (window_body_cols): Subtract display margins from the
2245 window body width on TTYs as well. See
2246 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
2247 for the original report.
2249 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
2251 * xdisp.c (redisplay_window): Remove inner local variable
2252 because the outer shadowed one has the same meaning.
2253 * xterm.h (struct x_output): Remove toolbar_detached member since it's
2255 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
2256 (xg_create_tool_bar): Adjust users.
2258 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
2260 * buffer.h (BUF_COMPACT): New macro to follow the common style.
2261 * buffer.c (Fget_buffer_create): Use it to set compact field of
2262 struct buffer_text to avoid accessing an uninitialized value
2263 when compact_buffer is called for the first time.
2264 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
2265 (Fset_buffer_modified_p): Use buffer_window_count to check
2266 whether the buffer is displayed in some window.
2267 * xdisp.c (message_dolog): Likewise.
2269 2012-12-23 Eli Zaretskii <eliz@gnu.org>
2271 * w32.c (acl_set_file): If setting the file security descriptor
2272 fails, and the new DACL is identical to the existing one, silently
2273 return success. This fixes problems for users backing up their
2274 own files without having the necessary privileges for setting
2275 security descriptors.
2277 * w32proc.c (reader_thread): Do not index fd_info[] with negative
2279 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
2280 after WaitForSingleObject returns normally. This expedites reader
2281 thread shutdown when delete_child triggers it.
2282 (reap_subprocess): More accurate commentary for why we call
2283 delete_child only when cp->fd is negative.
2285 * w32.c (sys_close): Do not call delete_child on a subprocess
2286 whose handle is not yet closed. Instead, set its file descriptor
2287 to a negative value, so that reap_subprocess will call
2288 delete_child on that subprocess when its SIGCHLD arrives.
2289 This avoids closing handles used for communications between sys_select
2290 and reader_thread, which doesn't give sys_select a chance to
2291 notice that the process exited and invoke the SIGCHLD handler for
2294 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
2296 * nsfns.m (Fns_do_applescript): Run event loop until script has
2297 been executed (Bug#12969).
2298 (ns_run_ascript): Chech as_script for nil, set to nil after
2301 2012-12-22 Martin Rudalics <rudalics@gmx.at>
2303 * window.c (Fselect_window): Reword doc-string (Bug#13248).
2305 2012-12-22 Eli Zaretskii <eliz@gnu.org>
2307 * w32term.c (w32fullscreen_hook): New function.
2308 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
2310 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2312 * fileio.c (Finsert_file_contents): Doc fix.
2314 * w32proc.c (new_child, delete_child, find_child_pid): For a
2315 subprocess, consider its slot being in use as long as its process
2316 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2317 slot when a new process is started immediately after killing
2318 another one, without waiting enough time for the first process to

2334 Remove now unused argument FNAME; all callers changed.
2335 (get_file_owner_and_group): Remove now unused argument FNAME; all
2338 2012-12-21 Chong Yidong <cyd@gnu.org>
2340 * editfns.c (Finsert_char): Since read-char-by-name now signals an

2384 * w32.c (acl_get_file, acl_set_file): Run the file name through

2401 * window.c (select_window_1): New func, extracted from select_window.
2402 (select_window): Use it.

2429 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
2431 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2432 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2433 for some of that bug's symptoms can now cause Emacs to abort.
2434 Remove the workaround.
2435 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2436 The bug that caused SIGCHLD to get lost has been fixed, and the
2437 workaround for it can now cause Emacs to abort.
2439 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2441 * sysdep.c (emacs_abort): Bump backtrace size to 40.

2481 * callproc.c (Fcall_process): Don't overwrite infile with result
2483 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
2484 asynchronous subprocess, record the name of the input file name,
2486 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
2487 delete the file, record it as pending deletion when the subprocess

2498 Fix permissions bugs with setgid directories etc. (Bug#13125)
2499 * dired.c (Ffile_attributes): Return t as the 9th attribute,

2510 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2512 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
2513 try to get accurate owner and group information from NT file
2514 security APIs. This is to make most callers of 'stat' and
2515 'lstat', which don't need that information, much faster.
2517 * dired.c (Ffile_attributes) [WINDOWSNT]:
2518 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2519 owner and group information from 'lstat'.
2521 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2523 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2524 as that confuses set-auto-coding, so insist on the head-read

2553 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2555 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2556 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2557 Remove unnecessary S_ISLNK test, as (contra the comments) this
2558 function can't copy symlinks. Improve quality of error message
2559 when attempting to copy files that are neither regular files nor

2578 * inotify.c (inotify_callback): Generate an Emacs event for every
2579 incoming inotify event.
2581 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2583 * xdisp.c (handle_face_prop): Fix logic of computing
2584 it->start_of_box_run_p.
2585 (append_space_for_newline): If the glyph row is R2L, reset the
2586 iterator's end_of_box_run_p flag before prepending the space glyph.
2587 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
2588 iterator's start_of_box_run_p flag before prepending the stretch.

2590 (append_stretch_glyph, append_glyphless_glyph): Reverse the
2591 left_box_line_p and right_box_line_p flags of the glyph for R2L
2592 glyph rows. (Bug#13011)

2801 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
2802 instead, use xputenv+unsetenv to set and restore TZ.
2803 (environbuf): Remove static var. All uses removed.
2804 (Fset_time_zone_rule): Do not save TZ and environ;
2805 no longer needed here.
2806 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
2807 Move to inside set_time_zone_rule; they don't need file scope any more.
2808 (set_time_zone_rule): Maintain the TZ=value string separately.
2809 (syms_of_editfns): Don't initialize initial_tz;
2810 init_editfns now does it.
2811 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
2812 * lisp.h (xputenv): New decl.
2814 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
2816 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
2818 2012-12-08 Eli Zaretskii <eliz@gnu.org>
2820 * w32.c (unsetenv, sys_putenv): New functions.
2822 2012-12-08 Chong Yidong <cyd@gnu.org>
2824 * editfns.c (Finsert_char): Make the error message more
2825 informative (Bug#12992).
2827 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
2829 Simplify get_lim_data.
2830 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
2831 Remove USG and vlimit methods; no longer used these days.
2832 Add #error catchall just in case.
2834 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
2835 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
2836 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
2837 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
2838 (deleted_pid_list, Fdelete_process, create_process)
2839 (record_child_status_change, handle_child_signal, deliver_child_signal)
2840 (init_process_emacs, syms_of_process):
2841 Assume SIGCHLD is defined.
2842 (parse_signal): Remove. All uses removed.
2843 (abbr_to_signal): New static function.
2844 (Fsignal_process): Use it to convert signal names to ints.
2845 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
2846 kill (getpgrp (), ...).
2847 (emacs_sigaction_init): Assume SIGCHLD is defined.
2848 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
2849 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
2850 * syssignal.h (EMACS_KILLPG): Remove.
2851 All uses replaced by 'kill' with a negative pid.
2852 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
2853 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
2855 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
2857 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
2858 This will cause a production Emacs to dump core instead of
2861 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2863 * frame.c (make_frame): Do not set window's buffer to t.
2864 * window.c (Fsplit_window_internal): Likewise. Previously it was
2865 used to indicate that the window is being set up. Now we use
2866 set_window_buffer for all new windows, so the condition in ...
2867 (Fset_window_buffer): ... is always true and can be removed.
2869 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2871 Convenient macro to check whether the buffer is hidden.
2872 * buffer.h (BUFFER_HIDDEN_P): New macro.
2873 * frame.c (make_frame): Use it. Adjust comment.
2874 * buffer.c (candidate_buffer): New function.
2875 (Fother_buffer, other_buffer_safely): Use it.
2877 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2879 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
2880 if the child process is still running. Instead, exit the wait
2881 loop and return zero. (Bug#13086)
2883 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2885 * frame.h (x_char_width, x_char_height): Remove prototypes.
2886 * w32term.h (x_char_width, x_char_height): Likewise.
2887 * xfns.c (x_char_width, x_char_height): Remove.
2888 * w32fns.c (x_char_width, x_char_height): Likewise.
2889 * nsfns.c (x_char_width, x_char_height): Likewise.

2896 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
2898 Fix a recently-introduced delete-process race condition.
2899 * callproc.c, process.h (record_kill_process):
2900 New function, containing part of the old call_process_kill.
2901 (call_process_kill): Use it.
2902 This does not change call_process_kill's behavior.
2903 * process.c (Fdelete_process): Use record_kill_process to fix a
2904 race condition that could cause Emacs to lose track of a child.
2906 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2908 Avoid code duplication between prev_frame and next_frame.
2909 * frame.c (candidate_frame): New function. Add comment.
2910 (prev_frame, next_frame): Use it. Adjust comment.
2912 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2914 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2915 fails, signal an error instead of continuing with an empty
2917 Encode expanded temp file pattern before passing it to mkstemp or
2920 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2921 Encode the file name before passing it to dostounix_filename, in
2922 case it will downcase it (under w32-downcase-file-names).
2925 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2927 Minor call-process cleanups.
2928 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2929 at the same time as other platforms, to simplify analysis.
2930 No need for fd0_volatile since we have synch_process_fd.
2931 Avoid needless emacs_close; arg is always negative.
2933 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2935 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2938 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2940 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2941 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2942 and mouse_face_hidden members to a bitfields.
2943 * frame.h (struct frame): Remove set-but-not-used space_width member.
2944 (FRAME_SPACE_WIDTH): Remove.
2945 * nsterm.m, w32term.c, xterm.c: Adjust users.
2946 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2947 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2948 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2949 members to a bitfields.
2951 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2953 Don't let call-process be a zombie factory (Bug#12980).
2954 Fixing this bug required some cleanup of the signal-handling code.
2955 As a side effect, this change also fixes a longstanding rare race
2956 condition whereby Emacs could mistakenly kill unrelated processes,
2957 and it fixes a bug where a second C-g does not kill a recalcitrant
2958 synchronous process in GNU/Linux and similar platforms.
2959 The patch should also fix the last vestiges of Bug#9488,
2960 a bug which has mostly been fixed on the trunk by other changes.
2961 * callproc.c, process.h (synch_process_alive, synch_process_death)
2962 (synch_process_termsig, sync_process_retcode):
2963 Remove. All uses removed, to simplify analysis and so that
2964 less consing is done inside critical sections.
2965 * callproc.c (call_process_exited): Remove. All uses replaced
2966 with !synch_process_pid.
2967 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2968 These take the role of what used to be in unwind-protect arg.
2970 (block_child_signal, unblock_child_signal):
2971 New functions, to avoid races that could kill innocent-victim processes.
2972 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2973 (call_process_kill): Record killed processes as deleted, so that
2974 zombies do not clutter up the system. Do this inside a critical
2975 section, to avoid a race that would allow the clutter.
2976 (call_process_cleanup): Fix code so that the second C-g works again
2977 on common platforms such as GNU/Linux.
2978 (Fcall_process): Create the child process in a critical section,
2979 to fix a race condition. If creating an asynchronous process,
2980 record it as deleted so that zombies do not clutter up the system.
2981 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2982 light of these changes. Omit unnecessary call to emacs_close
2983 before failure, as the unwind-protect code does that.
2984 * callproc.c (call_process_cleanup):
2985 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2986 * process.c (record_deleted_pid): New function, containing
2987 code refactored out of Fdelete_process.
2988 (Fdelete_process): Use it.
2989 (process_status_retrieved): Remove. All callers changed to use
2990 child_status_change.
2991 (record_child_status_change): Remove, folding its contents into ...
2992 (handle_child_signal): ... this signal handler. Now, this
2993 function is purely a handler for SIGCHLD, and is not called after
2994 a synchronous waitpid returns; the synchronous code is moved to
2995 wait_for_termination. There is no need to worry about reaping
2996 more than one child now.
2997 * sysdep.c (get_child_status, child_status_changed): New functions.
2998 (wait_for_termination): Now takes int * status and bool
2999 interruptible arguments, too. Do not record child status change;
3000 that's now the caller's responsibility. All callers changed.
3001 Reimplement in terms of get_child_status.
3002 (wait_for_termination_1, interruptible_wait_for_termination):
3003 Remove. All callers changed to use wait_for_termination.
3004 * syswait.h: Include <stdbool.h>, for bool.
3005 (record_child_status_change, interruptible_wait_for_termination):
3007 (record_deleted_pid, child_status_changed): New decls.
3008 (wait_for_termination): Adjust to API changes noted above.
3010 * bytecode.c, lisp.h (Qbytecode): Remove.
3011 No longer needed after 2012-11-20 interactive-p changes.
3013 2012-12-03 Eli Zaretskii <eliz@gnu.org>
3015 * xdisp.c (redisplay_window): If the cursor is visible, but inside
3016 the scroll margin, move point outside the margin. (Bug#13055)
3018 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
3020 * gtkutil.c (my_log_handler): New function.
3021 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
3023 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3025 * lisp.h (modify_region): Rename to...
3026 (modify_region_1): ...new prototype.
3027 * textprop.c (modify_region): Now static. Adjust users.
3028 * insdel.c (modify_region): Rename to...
3029 (modify_region_1): ...new function to work with current buffer.
3030 Adjust comment and users. Use true and false for booleans.
3032 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3034 * alloc.c (free_save_value): New function.
3035 (safe_alloca_unwind): Use it.
3036 * lisp.h (free_save_value): New prototype.
3037 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
3039 (save_excursion_restore): Adjust to match saved data structure.
3040 Use free_save_value to offload some work from GC. Drop obsolete
3043 2012-12-03 Chong Yidong <cyd@gnu.org>
3045 * fileio.c (Vauto_save_list_file_name): Doc fix.
3047 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
3049 * w32fns.c: Remove prototype of atof.
3050 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
3052 (file_dialog_callback): Make it UINT_PTR.
3054 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
3057 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3058 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
3061 2012-12-03 Glenn Morris <rgm@gnu.org>
3063 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
3065 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
3067 Fix xpalloc confusion after memory is exhausted.
3068 * alloc.c (xpalloc): Comment fix.
3069 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
3070 and signals an error, do not clear charset_table_size, as
3071 charset_table is still valid.
3072 * doprnt.c (evxprintf): Clear *BUF after freeing it.
3074 Use execve to avoid need to munge environ (Bug#13054).
3075 * callproc.c (Fcall_process):
3076 * process.c (create_process):
3077 Don't save and restore environ; no longer needed.
3078 * callproc.c (child_setup):
3079 Use execve, not execvp, to preserve environ.
3081 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
3083 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
3085 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3087 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
3088 display for sliced images (Bug#10500).
3090 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
3092 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
3094 * doc.c (Fdocumentation): Re-add handling of function-documentation,
3095 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
3097 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
3099 * xdisp.c (window_outdated): Remove eassert since it hits
3100 some suspicious corner cases (see Bug#13007 and Bug#13012).
3101 (mode_line_update_needed): New function.
3102 (redisplay_internal, redisplay_window): Use it.
3103 (ensure_selected_frame): New function.
3104 (redisplay_internal, unwind_redisplay): Use it.
3105 (redisplay_internal): Move comment about buffer_shared...
3106 (buffer_shared_and_changed): ...near to its real use.
3108 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
3110 * callproc.c (Fcall_process): Don't misreport vfork failure.
3112 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
3114 * callproc.c (Fcall_process): Fix vfork portability problems.
3115 Do not assume that fd[0], count, filefd, and save_environ survive
3116 vfork. Fix bug whereby wrong errno value could be reported for
3117 pipe failure. Some minor cleanups, too, as follows. Move buf and
3118 bufsize to the context where they're needed. Change new_argv to
3119 be of type char **, as this is more convenient and avoids casts.
3120 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
3121 Now local constants, not macros.
3123 2012-11-18 Kenichi Handa <handa@gnu.org>
3125 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
3126 for the variable "f".
3128 2012-11-13 Kenichi Handa <handa@gnu.org>
3130 * font.c (font_unparse_xlfd): Exclude special characters from the
3131 generating XLFD name.
3133 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
3135 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

3146 * lread.c (readbyte_from_file): Assume EINTR is defined.
3147 * process.c (wait_reading_process_output, send_process) [subprocesses]:
3148 Assume EIO and EAGAIN are defined.
3149 * unexcoff.c (write_segment): Assume EFAULT is defined.
3151 2012-11-27 Eli Zaretskii <eliz@gnu.org>
3153 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
3156 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
3157 highlighting on the frame was cleared. Prevents assertion
3158 violations when repeatedly clicking on the "Top" link of the
3159 "bread-crumbs" in Info buffers.
3161 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
3163 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
3165 2012-11-24 Ken Brown <kbrown@cornell.edu>
3167 * keyboard.c (HAVE_MOUSE):
3168 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
3169 were always defined.
3171 2012-11-24 Eli Zaretskii <eliz@gnu.org>
3173 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
3174 between bpos_covered and bpos_max. This fixes cursor display when
3175 several display strings follow each other.
3177 * .gdbinit (pgx): If the glyph's object is a string, display the
3178 pointer to string data, rather than the value of the string object
3179 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
3181 * indent.c (Fvertical_motion): If the starting position is covered
3182 by a display string, return to one position before that, to avoid
3183 overshooting it inside move_it_to. (Bug#12930)
3185 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
3187 * frame.h (struct frame): Remove display_preempted member

3190 * w32menu.c (pending_menu_activation): Remove since not
3192 (set_frame_menubar): Adjust user.
3193 * w32term.h (struct x_output): Drop outdated #if 0 code.
3194 (struct w32_output): Use bitfields for explicit_parent,
3195 asked_for_visible and menubar_active members.
3196 Drop unused pending_menu_activation member.
3197 * xterm.h (struct x_output): Drop outdated #if 0 code.
3198 Use bitfields for explicit_parent, asked_for_visible,
3199 has_been_visible and net_wm_state_hidden_seen members.
3201 2012-11-23 Eli Zaretskii <eliz@gnu.org>
3203 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
3204 of a literal "/". (Bug#12955)
3205 (gl-stamp): Invoke fc.exe directly, not through cmd.
3207 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
3209 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
3210 * dired.c: Assume HAVE_DIRENT_H.
3211 (NAMLEN): Remove, replacing with ...
3212 (dirent_namelen): New function. All uses changed. Use the GNU macro
3213 _D_EXACT_NAMELEN if available, as it's faster than strlen.
3214 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
3215 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
3216 * makefile.w32-in (DIR_H): Remove. All uses replaced with
3218 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
3219 * ndir.h: Rename to ../nt/inc/dirent.h.
3220 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
3221 Do not include <dirent.h>; no longer needed.
3222 * w32.c: Include <dirent.h> rather than "ndir.h".
3224 2012-11-23 Chong Yidong <cyd@gnu.org>
3226 * xftfont.c (xftfont_open): Remove duplicate assignment.
3228 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3230 * alloc.c (Fgarbage_collect): Unblock input after clearing
3231 gc_in_progress to avoid note_mouse_highlight glitch with GC.
3232 * frame.h (FRAME_MOUSE_UPDATE): New macro.
3233 * msdos.c (IT_frame_up_to_date): Use it here...
3234 * w32term.c (w32_frame_up_to_date): ...here...
3235 * xterm.c (XTframe_up_to_date): ...and here...
3236 * nsterm.m (ns_frame_up_to_date): ...but not here.
3237 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
3239 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
3240 Do not check whether GC is in progress.
3242 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3244 * xdisp.c (window_buffer_changed): New function.
3245 (update_menu_bar, update_tool_bar): Use it to
3246 simplify large 'if' statements.
3247 (redisplay_internal): Generalize commonly used
3248 'tail' and 'frame' local variables.
3250 2012-11-22 Eli Zaretskii <eliz@gnu.org>
3252 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
3253 with Windows system header.
3255 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
3257 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
3258 * alloc.c: Assume unistd.h exists.
3259 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
3260 * sysdep.c (get_current_dir_name): Assume getcwd exists.
3261 (getwd) [USG]: Remove; no longer needed.
3262 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
3263 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
3264 * w32.h (getcwd): Remove decl.
3266 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
3268 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
3269 Make it set selected_window as well.
3270 (update_tool_bar): Use it.
3272 2012-11-21 Ken Brown <kbrown@cornell.edu>
3274 * emacs.c (main): Set the G_SLICE environment variable for all
3275 Cygwin builds, not just GTK builds. See
3276 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
3278 2012-11-21 Eli Zaretskii <eliz@gnu.org>
3280 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3281 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
3282 Define for the MSVC compiler.
3284 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
3286 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
3287 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
3288 dostounix_filename. Prevents crashes down the road, because
3289 dostounix_filename assumes it gets a unibyte string.
3290 Reported by Michel de Ruiter <michel@sentient.nl>, see
3291 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
3293 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
3295 Conflate Qnil and Qunbound for `symbol-function'.

3297 * lread.c (init_obarray): Set `function' fields to Qnil.
3298 * eval.c (Fcommandp): Ignore Qunbound.
3299 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
3300 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
3301 Test NILP rather than Qunbound.
3302 (Ffmakunbound): Set to Qnil.
3303 (Fsymbol_function): Never signal an error.
3304 (Finteractive_form): Ignore Qunbound.
3306 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
3308 * eval.c (interactive_p): Remove no-longer-used decl.
3310 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
3312 * xdisp.c (buffer_shared): Adjust comment.
3313 (buffer_shared_and_changed): New function.
3314 (prepare_menu_bars, redisplay_internal): Use it to
3315 decide whether all windows or frames should be updated.
3316 (window_outdated): New function.
3317 (text_outside_line_unchanged_p, redisplay_window): Use it.
3318 (redisplay_internal): Likewise. Fix indentation.
3320 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
3322 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
3323 (syms_of_eval): Remove corresponding defsubr.
3324 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
3326 2012-11-19 Daniel Colascione <dancol@dancol.org>
3328 * w32fns.c (Fx_file_dialog):
3329 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
3330 cygwin_convert_file_name*.
3332 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
3333 Rename cygwin_convert_path* to cygwin_convert_file_name*.
3335 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
3337 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3339 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3341 * w32select.c: Include w32common.h before w32term.h, so that
3342 windows.h gets included before w32term.h uses some of its
3343 features, see below.
3345 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3347 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
3349 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
3351 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
3353 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
3354 (ns_select): Return at once if events are held (Bug#12834).
3356 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3358 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3359 Needed following 2012-10-20 change. (Bug#12902)
3361 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3363 * w32proc.c (waitpid): Remove unused label get_result.
3365 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3367 * makefile.w32-in (SYSWAIT_H): New macro.
3368 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3369 ($(BLD)/sysdep.$(O)): Update dependencies.
3371 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3373 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
3374 * callproc.c (relocate_fd): Assume F_DUPFD.
3375 * emacs.c, term.c (O_RDWR): Remove.
3376 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3377 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3378 * nsterm.m: Assume <fcntl.h> exists.
3379 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3380 (create_pty, Fmake_network_process, server_accept_connection)
3381 (wait_reading_process_output, init_process_emacs):
3383 (wait_reading_process_output): Put in a special case for WINDOWSNT
3384 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3385 It's not clear this is needed, but it's a more-conservative change.
3386 (create_process): Assume FD_CLOEXEC.
3387 (create_process, create_pty): Assume O_NOCTTY.
3388 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3389 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3390 Omit if not DOS_NT, since F_GETFL is not defined there.
3391 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3392 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3394 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3395 lack it, since gnulib guarantees this.
3396 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3398 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3400 * w32.c (faccessat): Pretend that directories have the execute bit
3401 set. Emacs expects that, e.g., in files.el:cd-absolute.
3403 * w32proc.c (create_child): Don't clip the PID of the child
3404 process to fit into an Emacs integer, as this is no longer a
3406 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3407 reaping only the process specified by PID argument, if that is
3408 positive. Use PID instead of dead_child to know which process to
3409 reap. Wait for the child to die only if WNOHANG is not in
3411 (sys_select): Don't set dead_child.
3413 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3414 as it is no longer needed.
3416 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3418 (record_child_status_change): Remove the setting of
3419 record_at_most_one_child for the !WNOHANG case.
3421 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3423 Fix problems in ns port found by static checking.
3424 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3425 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3426 not to process group.
3427 (ns_select): Use emacs_write, not write, as that's more robust
3428 in the presence of signals.
3429 (fd_handler:): Check for read errors.
3431 2012-11-16 Glenn Morris <rgm@gnu.org>
3433 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3435 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3437 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3439 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3441 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3442 use the same value of thread handle.
3443 (start_timer_thread): If the timer thread exited (due to error),
3444 clean up by closing the two handles it used. Duplicate the caller
3445 thread's handle here, so it gets duplicated only once, when
3446 launching the timer thread. Set priority of the timer thread, not
3448 (getitimer): Don't duplicate the caller thread's handle here.
3451 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3453 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3456 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3458 Remove no-longer-used pty_max_bytes variable.
3459 * process.c (pty_max_bytes): Remove; unused.
3460 (send_process): Do not set it.
3462 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3464 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3465 Update dependencies.
3467 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3469 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3470 This follows up on the 2012-09-29 patch that removed indirection
3471 for the 'function' field. Reported by Sergey Vinokurov in
3472 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3474 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3476 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3477 different name, as the MS runtime does not have such a function,
3478 and probably never will.) All callers changed. Ignore DIRFD
3479 value if PATH is an absolute file name, to match Posix spec
3480 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3483 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3485 * xdisp.c (echo_area_display, redisplay_internal):
3486 Omit redundant check whether frame_garbaged is set.
3488 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3490 Use faccessat, not access, when checking file permissions (Bug#12632).
3491 This fixes a bug that has been present in Emacs since its creation.
3492 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3493 which must set some sort of record. (Torek's bug report was against
3494 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3495 same common flaw.) See Torek's Usenet posting
3496 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3497 Posted: Fri Apr 8 14:18:56 1983.
3498 * Makefile.in (LIB_EACCESS): New macro.
3500 * callproc.c (init_callproc):
3501 * charset.c (init_charset):
3502 * fileio.c (check_existing, check_executable, check_writable)
3504 * lread.c (openp, load_path_check):
3505 * process.c (allocate_pty):
3507 Use effective UID when checking permissions, not real UID.
3508 * callproc.c (init_callproc):
3509 * charset.c (init_charset):
3510 * lread.c (load_path_check, init_lread):
3511 Test whether directories are accessible, not merely whether they exist.
3512 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3513 * fileio.c (check_existing, check_executable, check_writable)
3515 Use symbolic names instead of integers for the flags, as they're
3517 (check_writable): New arg AMODE. All uses changed.
3518 Set errno on failure.
3519 (Ffile_readable_p): Use faccessat, not stat + open + close.
3520 (Ffile_writable_p): No need to call check_existing + check_writable.
3521 Just call check_writable and then look at errno. This saves a syscall.
3522 dir should never be nil; replace an unnecessary runtime check
3523 with an eassert. When checking the parent directory of a nonexistent
3524 file, check that the directory is searchable as well as writable, as
3525 we can't create files in unsearchable directories.
3526 (file_directory_p): New function, which uses 'stat' on most platforms
3527 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3528 (Ffile_directory_p, Fset_file_times): Use it.
3529 (file_accessible_directory_p): New function, which uses a single
3530 syscall for efficiency.
3531 (Ffile_accessible_directory_p): Use it.
3532 * xrdb.c (file_p): Use file_directory_p.
3533 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3534 * lread.c (openp): When opening a file, use fstat rather than
3535 stat, as that avoids a permissions race. When not opening a file,
3536 use file_directory_p rather than stat.
3537 (dir_warning): First arg is now a usage string, not a format.
3538 Use errno. All uses changed.
3539 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3540 that merely introduced a race.
3541 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3542 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3543 and similarly for the other O_* flags.
3544 * w32.c (sys_faccessat): Rename from sys_access and switch to
3545 faccessat's API. All uses changed.
3546 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3547 (magic_db): Rename from magic_file_p.
3548 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3549 char *, so that we don't have to test for file existence
3550 separately from opening the file for reading. This removes a race
3551 fixes a permission-checking problem, and simplifies the code.
3553 (file_p): Remove; no longer needed.
3555 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3557 Omit glyphs initialization at startup.
3558 * dispnew.c (glyphs_initialized_initially_p): Remove.
3559 (adjust_frame_glyphs_initially): Likewise. Adjust users.
3560 (Fredraw_frame): Move actual code from here...
3561 (redraw_frame): ...to here. Add eassert. Adjust comment.
3562 (Fredraw_display): Use redraw_frame.
3563 * xdisp.c (clear_garbaged_frames): Likewise.
3565 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3567 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3568 passed to pint2str and pint2hrstr to be at most the size of the
3569 frame's decode_mode_spec_buffer. This avoids crashes with very
3570 large values of FIELD_WIDTH argument to decode_mode_spec.
3573 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3575 Fix a race with verify-visited-file-modtime (Bug#12863).
3576 Since at least 1991 Emacs has ignored an mtime difference of no
3577 more than one second, but my guess is that this was to work around
3578 file system bugs that were fixed long ago. Since the race is
3579 causing problems now, let's remove that code.
3580 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3581 whose time stamp is off by no more than a second. Insist that the
3582 file time stamps match exactly.
3584 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3586 * frame.h (struct frame): Convert external_tool_bar member to
3587 1-bit unsigned bitfield.
3588 * termhooks.h (struct terminal): Remove mouse_moved member since
3589 all users are long dead. Adjust comment on mouse_position_hook.
3591 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3593 Simplify by using FOR_EACH_FRAME here and there.
3594 * frame.c (next_frame, prev_frame, other_visible_frames)
3595 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
3596 * w32term.c (x_window_to_scroll_bar): Likewise.
3597 * window.c (window_list): Likewise.
3598 * xdisp.c (x_consider_frame_title): Likewise.
3599 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
3600 * xfns.c (x_window_to_frame, x_any_window_to_frame)
3601 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
3602 * xmenu.c (menubar_id_to_frame): Likewise.
3603 * xselect.c (frame_for_x_selection): Likewise.
3604 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3605 (x_window_to_menu_bar): Likewise.
3606 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3608 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3610 * data.c (Qdefalias_fset_function): Now static.
3612 Another tweak to vectorlike_header change.
3613 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3614 Remove, and replace all uses with ...
3615 (next_in_free_list, set_next_in_free_list):
3616 New functions, which respect C's aliasing rules better.
3618 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3620 * window.c (list4i): Rename from 'quad'. All uses changed.
3621 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3623 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3625 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3626 warning about mixing declarations and code in ISO C90.
3628 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3630 * window.c (Fsplit_window_internal): Set combination limit of
3631 new parent window to t iff Vwindow_combination_limit is t;
3632 fixing a regression introduced with the change from 2012-09-22.
3633 (Fset_window_combination_limit): Fix doc-string.
3635 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3637 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3638 amount when the scroll margins are too large. When scrolling
3639 backwards in the buffer, give up if cannot reach point or the
3640 scroll margin within a reasonable number of screen lines.
3641 Fixes point position in window under scroll-up/down-aggressively when
3642 point is positioned many lines beyond the window top/bottom.
3645 * ralloc.c (relinquish): If real_morecore fails to return memory
3646 to the system, don't crash; instead, leave the last heap
3647 unchanged and return. (Bug#12774)
3649 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3651 * lisp.h (AUTOLOADP): New macro.
3652 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
3653 * data.c (Ffset): Remove special ad-advice-info handling.
3654 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
3656 (Finteractive_form): Simplify.
3657 (Fquo): Don't insist on having at least 2 arguments.
3658 (Qdefalias_fset_function): New var.
3660 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3662 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
3664 * nsfont.m (Qcondensed, Qexpanded): New variables.
3665 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
3666 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
3668 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3670 Fix recently introduced crash on MS-Windows (Bug#12839).
3671 * w32term.h (struct scroll_bar): Use convenient header.
3672 (SCROLL_BAR_VEC_SIZE): Remove.
3673 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3675 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3677 Tweak last vectorlike_header change.
3678 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3679 vectorlike object on the free list. This is introduced to avoid
3680 some (but not all) pointer casting and aliasing problems, see
3681 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3682 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
3684 (xvectype, xvecsize): Use them to examine Lisp_Object values.
3686 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3688 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3689 been removed, so remove them here also.
3691 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3693 * doc.c (Fdocumentation): Handle new property
3694 dynamic-docstring-function to replace the old ad-advice-info.
3696 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
3698 * fns.c (Qeql, hashtest_eq): Now static.
3700 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3702 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
3703 * fns.c (hashfn_eq, hashfn_eql, sxhash):
3704 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.

3711 * lisp.h (sxhash_combine): New inline function, with the contents
3712 of the old SXHASH_COMBINE.
3713 * profiler.c (hashfn_profiler): Use it, instead of having a
3714 special hash function containing a comparison that always yields 1.
3716 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3718 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3719 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3720 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3723 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3725 * image.c (xpm_make_color_table_h): Fix compiler error because
3726 make_hash_table changed.
3728 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
3730 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3732 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3734 Use ad-hoc comparison function for the profiler's hash-tables.
3735 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3736 (make_log): Use them.
3737 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3738 call Fequal any more.

3747 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
3748 (hash_lookup, hash_remove_from_table): Move assertion checking of
3749 hashfn result here. Check hash-equality before calling cmpfn.

3759 2012-11-08 Eli Zaretskii <eliz@gnu.org>
3761 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
3762 value of w32-scroll-lock-modifier is neither nil nor one of the
3763 known key modifiers. (Bug#12806)
3765 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3767 Shrink struct vectorlike_header to the only size field.
3768 * lisp.h (enum pvec_type): Avoid explicit enum member values.
3770 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
3771 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
3772 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
3773 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
3774 information from the vector header. Adjust comment.

3789 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3790 (large_vectors): Change type to struct large_vector.
3791 (allocate_vector_from_block): Simplify.
3792 (PSEUDOVECTOR_NBYTES): Replace with...
3793 (vector_nbytes): ...new function. Adjust users.
3794 (sweep_vectors): Adjust processing of large vectors.
3795 (allocate_vectorlike): Likewise.
3796 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
3797 Add easserts. Adjust XSETPVECTYPESIZE usage.
3798 (allocate_buffer): Use BUFFER_PVEC_INIT.
3799 (live_vector_p): Adjust to match large vector.
3800 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
3801 * buffer.h (struct buffer): Add next member.
3802 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
3804 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

3810 (xvecsize): New command.
3812 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3814 * keyboard.c (event_to_kboard): Do not dereference
3815 frame_or_window field of SELECTION_REQUEST_EVENT
3816 and SELECTION_CLEAR_EVENT events (Bug#12814).
3817 * xterm.h (struct selection_input_event): Adjust comment.
3819 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3821 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3822 such as Scroll Lock, if the respective keys are treated as
3823 function keys, not as modifiers. This avoids destroying non-ASCII
3824 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3826 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3828 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3830 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3832 Restore some duplicate definitions (Bug#12814).
3833 This undoes part of the 2012-11-03 changes. Some people build
3834 with plain -g rather than with -g3, and they need the duplicate
3835 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3836 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3837 Define as macros, as well as as enums or as constants.
3839 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
3841 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
3842 to keypad keys (Bug#12816).
3844 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3846 Minor adjustments of recently-changed frame functions.
3847 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3848 known to be a frame (we're in the FRAMEP branch).
3849 * lisp.h (Qframep): Remove decl. frame.h declares this.
3850 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3851 since they're meant for Lisp fixnum values.
3853 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3855 * window.c (Fwindow_combination_limit): Revert to the only
3856 required argument and adjust docstring as suggested in
3857 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3858 by Martin Rudalics <rudalics@gmx.at>.
3860 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3862 Widely used frame validity and checking functions.
3863 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
3864 * frame.c (decode_live_frame, decode_any_frame): New functions.
3865 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
3866 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
3867 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)

3874 (frame_buffer_list, frame_buffer_predicate): Remove.
3875 * lisp.h (frame_buffer_predicate): Remove prototype.
3876 * buffer.c (Fother_buffer): Use decode_any_frame.
3877 * xdisp.c (Ftool_bar_lines_needed): Likewise.
3878 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3879 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3880 (Fclose_font, Ffont_info): Use decode_live_frame.
3881 * fontset.c (check_fontset_name): Likewise.
3882 * terminal.c (Fframe_terminal): Likewise.
3883 * w32fns.c (check_x_frame): Likewise.
3884 * window.c (Fminibuffer_window, Fwindow_at)
3885 (Fcurrent_window_configuration): Likewise.
3886 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
3887 Likewise. Allow zero number of arguments. Adjust docstring.
3888 * dispnew.c (Fredraw_frame): Likewise.
3889 * xfaces.c (frame_or_selected_frame): Remove.
3890 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3891 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3892 (Fframe_face_alist): Use decode_live_frame.
3893 * xfns.c (check_x_frame): Likewise.
3895 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3897 * window.c (quad): New function.
3898 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3899 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3900 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3901 (Fwindow_line_height): Use it.
3902 (Fwindow_fringes): Use list3.
3903 (Fwindow_scroll_bars): Use list4.
3904 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3905 (Fwindow_combination_limit): Allow zero number of arguments.
3907 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3909 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3911 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3912 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3913 file descriptor 2 for standard error. (Bug#12805)
3915 2012-11-05 Chong Yidong <cyd@gnu.org>
3917 * process.c (wait_reading_process_output): Revert previous change.
3919 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3921 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3922 This removes code that has been obsolete since around 1990.
3923 * callproc.c (Fcall_process):
3925 * process.c (create_process):
3926 * term.c (dissociate_if_controlling_tty):
3927 Assume setsid exists.
3928 * callproc.c (child_setup): Assume setpgid exists and behaves as
3929 per POSIX.1-1988 or later.
3930 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3931 * emacs.c (shut_down_emacs):
3932 * sysdep.c (sys_suspend, init_foreground_group):
3933 Assume getpgrp behaves as per POSIX.1-1998 or later.
3934 * msdos.c (setpgrp): Remove.
3935 (tcgetpgrp, setpgid, setsid): New functions.
3936 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3937 * term.c (no_controlling_tty): Remove; unused.
3938 * w32proc.c (setpgrp): Remove.
3939 (setsid, tcgetpgrp): New functions.
3941 Simplify by assuming __fpending.
3942 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3943 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3944 Do not assume that __fpending's result fits in int.
3946 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3948 Remove EMACS_OUTQSIZE+sleep hack.
3949 * dispnew.c (update_frame_1): Remove hack for terminals slower
3950 than 2400 bps, which throttled Emacs by having it sleep.
3951 This code hasn't worked since at least 2007, when the multi-tty stuff
3952 was added, and anyway those old terminals are long dead.
3953 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3954 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3956 Fix data-loss with --version (Bug#9574).
3957 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3958 as we can't assume that emacs_strerror is initialized, and strerror
3959 is good enough here.
3960 (main): Invoke atexit earlier, to catch earlier instances of
3961 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3963 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3965 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3966 (keyDown): Remap keypad keys to X11 virtual key codes.
3968 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3970 Fix data-loss with --batch (Bug#9574).
3971 * emacs.c: Include <close-stream.h>.
3972 (close_output_streams): New function.
3973 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3974 and handles errors appropriately.
3975 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3978 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3979 The symptom is a diagnostic "GLib-WARNING **: In call to
3980 g_spawn_sync(), exit status of a child process was requested but
3981 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3982 waitpid(), so exit status can't be returned." The diagnostic
3983 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3984 The real bug is a race condition between Emacs and glib: Emacs
3985 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3986 so that glib can't find it. Work around the bug by invoking
3987 waitpid only on subprocesses that Emacs itself creates.
3988 * process.c (create_process, record_child_status_change):
3989 Don't use special value -1 in pid field, as the caller now must
3990 know the pid rather than having the callee infer it.
3991 The inference was sometimes incorrect anyway, due to another race.
3992 (create_process): Set new 'alive' member if child is created.
3993 (process_status_retrieved): New function.
3994 (record_child_status_change): Use it.
3995 Accept negative 1st argument, which means to wait for the
3996 processes that Emacs already knows about. Move special-case code
3997 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3998 processes that have already been waited for, by testing and
3999 clearing new 'alive' member.
4000 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
4001 now does this internally.
4002 (handle_child_signal): Let record_child_status_change do all
4003 the work, since we do not want to reap all exited child processes,
4004 only the child processes that Emacs itself created.
4005 * process.h (Lisp_Process): New boolean member 'alive'.
4007 Omit duplicate definitions no longer needed with gcc -g3.
4008 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
4009 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
4010 Define only as macros. There's no longer any need to also define
4011 these symbols as enums or as constants, since we now assume
4012 gcc -g3 when debugging.
4014 2012-11-03 Eli Zaretskii <eliz@gnu.org>
4016 * lisp.mk: Adjust comments to the fact that term/internal is now
4017 loaded from loadup.el.
4019 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
4020 (msdos_fatal_signal): New function.
4021 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
4024 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
4025 for GCC versions before 4.
4026 (emacs_raise): Define to call msdos_fatal_signal.
4028 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
4029 iterator when starting in the middle of a display or overlay
4032 2012-11-03 Chong Yidong <cyd@gnu.org>
4034 * process.c (wait_reading_process_output): Clean up the last
4037 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
4039 * process.c (wait_reading_process_output): Avoid a race condition
4040 with SIGIO delivery (Bug#11536).
4042 2012-11-03 Chong Yidong <cyd@gnu.org>
4044 * buffer.c (cursor_type): Untabify docstring.
4046 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4048 * frame.h (struct frame): Drop can_have_scroll_bars member
4049 which is meaningless for a long time. Adjust comments.
4050 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
4051 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
4053 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4055 * window.c (decode_next_window_args): Update window arg after
4056 calling decode_live_window and so fix crash reported at
4057 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
4058 by Juanma Barranquero <lekktu@gmail.com>.
4059 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
4060 * font.c (Ffont_at): Likewise.
4062 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
4064 * widget.c (resize_cb): New function.
4065 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
4066 (EmacsFrameResize): Check if all is up to date before changing frame
4069 2012-11-02 Eli Zaretskii <eliz@gnu.org>
4071 Implement backtrace output for fatal errors on MS-Windows.
4072 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
4073 (BACKTRACE_LIMIT_MAX): New macro.
4074 (w32_backtrace): New function.
4075 (emacs_abort): Use w32_backtrace when the user chooses not to
4076 attach a debugger. Update the text of the abort dialog.
4078 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4080 Window-related stuff cleanup here and there.
4081 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
4082 Use decode_any_window.
4083 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
4084 * xdisp.c (Fformat_mode_line): Likewise.
4085 * font.c (Ffont_at): Use decode_live_window.
4086 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
4087 * window.c (decode_next_window_args): Likewise.
4088 (decode_any_window): Remove static.
4089 * window.h (decode_any_window): Add prototype.
4090 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
4091 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
4094 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4096 Remove pad from struct input_event.
4097 * termhooks.h (struct input_event): Remove padding field.
4099 * keyboard.c (event_to_kboard): Simplify because frame_or_window
4100 member is never cons for a long time. Adjust comment.
4101 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
4102 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
4103 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
4104 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
4106 2012-11-01 Eli Zaretskii <eliz@gnu.org>
4108 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
4110 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
4112 Fix crash when using Emacs as commit editor for git (Bug#12697).
4113 * callproc.c (setpgrp): Remove macro, as we now use setpgid
4114 and it is configured in conf_post.h.
4115 (Fcall_process): Don't invoke both setsid and setpgid; the former
4116 is enough, if it exists.
4117 * callproc.c (Fcall_process, child_setup):
4118 * process.c (create_process): Use setpgid.
4119 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
4121 * dispnew.c (init_display): Initialize the foreground group
4122 if we are running a tty display.
4123 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
4124 * lisp.h (init_foreground_group): New decl.
4125 * sysdep.c (inherited_pgroup): New static var.
4126 (init_foreground_group, tcsetpgrp_without_stopping)
4127 (narrow_foreground_group, widen_foreground_group): New functions.
4128 (init_sys_modes): Narrow foreground group.
4129 (reset_sys_modes): Widen foreground group.

4135 2012-10-31 Martin Rudalics <rudalics@gmx.at>
4137 * minibuf.c (read_minibuf): Restore current buffer since
4138 choose_minibuf_frame calling Fset_frame_selected_window may
4139 change it (Bug#12766).
4141 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
4143 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
4145 2012-10-30 Kenichi Handa <handa@gnu.org>
4147 * font.c (Ffont_at): If WINDOW is specified and it is not
4148 displaying the current buffer, signal an error.
4150 2012-10-29 Daniel Colascione <dancol@dancol.org>
4152 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
4153 In preparation for fixing bug#12739, move these functions from
4156 * coding.h, coding.c: ... to here, and compile them only when
4157 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
4158 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
4160 2012-10-28 Eli Zaretskii <eliz@gnu.org>
4162 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
4163 (timer_loop, getitimer, setitimer): Use it instead of
4164 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
4166 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
4169 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
4171 * nsterm.m (NO_APPDEFINED_DATA): New define.

4173 (last_appdefined_event): Remove.
4174 (ns_select): Initialize t from last_appdefined_event_data instead
4175 of [last_appdefined_event data1].
4176 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
4177 remove last_appdefined_event (Bug#12698).
4179 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
4181 * frame.c (x_set_font): Catch internal error.
4183 2012-10-27 Eli Zaretskii <eliz@gnu.org>
4185 Avoid overflow in w32 implementation of interval timers.
4186 When possible, for ITIMER_PROF count only times the main thread
4188 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
4189 'volatile ULONGLONG' types. All the other data which was
4190 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
4191 (GetThreadTimes_Proc): New typedef.
4192 (w32_get_timer_time): New function, returns a suitable time value
4194 (timer_loop): Enter critical section when accessing ULONGLONG
4195 values of the itimer_data struct, as these accesses are no longer
4196 atomic. Call 'w32_get_timer_time' instead of 'clock'.
4197 Remove unused variable.
4198 (init_timers): Initialize s_pfn_Get_Thread_Times.
4199 (start_timer_thread): Don't assign itimer->caller_thread here.
4200 (getitimer): Assign itimer->caller_thread here.

4206 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
4207 mouse movement events if the menu bar is active. This avoids
4208 producing a busy "hour-glass" cursor by Windows if the mouse
4209 pointer is positioned over a tooltip shown for some menu item.
4211 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
4213 Don't assume process IDs fit in int.
4214 * emacs.c (shut_down_emacs) [!DOS_NT]:
4215 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
4216 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
4217 Use pid_t, not int, to store process IDs, as 'int'
4218 is not wide enough on a few platforms (e.g., AIX and IRIX).
4220 2012-10-23 Kenichi Handa <handa@gnu.org>
4222 The following change is to make face-font-rescale-alist work
4223 correctly for non-ASCII fonts.
4225 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
4226 (font_open_for_lface): Handle Vface_font_rescale_alist.
4228 2012-10-23 Chong Yidong <cyd@gnu.org>
4230 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
4232 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

4241 2012-10-21 Glenn Morris <rgm@gnu.org>
4243 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
4245 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
4247 Port to OpenBSD 5.1.
4248 * frame.c (Fmouse_position, Fmouse_pixel_position):
4249 * xdisp.c (produce_stretch_glyph):
4250 Declare local vars only when they're needed.
4251 This is clearer and avoids a warning on OpenBSD about unused vars.

4253 This is safer, and avoids OpenBSD warnings about unused vars.
4254 * keyboard.c (record_menu_key): Remove unnecessary decl.
4255 (poll_timer): Define only if POLL_FOR_INPUT is defined.
4256 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
4257 as our definition clashes with OpenBSD's.
4258 * xfaces.c (load_face_colors, check_lface_attrs)
4259 (get_lface_attributes_no_remap, get_lface_attributes)
4260 (lface_fully_specified_p, x_supports_face_attributes_p)
4261 (tty_supports_face_attributes_p, face_fontset, realize_face)
4262 (realize_x_face, realize_tty_face):
4263 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
4264 merely Lisp_Object *. This is more informative and avoids
4265 a warning on OpenBSD about accessing beyond an object's size.
4267 2012-10-20 Chong Yidong <cyd@gnu.org>
4269 * lread.c (Fload): Doc fix (Bug#12592).

4295 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
4296 (staticpro): If we run out of staticpro slots, die with an
4297 informative error instead of just calling emacs_abort.
4299 2012-10-18 Martin Rudalics <rudalics@gmx.at>
4301 Fix two flaws reported by Dmitry Antipov.

4556 since unsigned is guaranteed to have that behavior and signed is not.

4558 (get_input_pending): Remove first argument, since it was always
4559 the same pointer-to-int (now pointer-to-boolean) &input_pending,
4560 and behave as if it had that value. Return new value of
4561 input_pending. All callers changed.
4562 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
4563 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

4606 match what GetLastError returns. Explain why the function is
4609 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
4610 'is_tooltip_frame', to avoid confusion with its global namesake.
4612 2012-10-08 Daniel Colascione <dancol@dancol.org>
4614 * xdisp.c (start_hourglass): Call w32_note_current_window when
4615 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
4616 build that caused Emacs to display the hourglass cursor forever.
4618 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
4619 which is broken under remote desktop, calculate the number of
4620 colors available for a display based on the display's number of
4621 planes and number of bits per pixel per plane. (bug#10397).
4623 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
4625 * nsfont.m (Vfonts_in_cache): New variable.
4626 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
4627 are used. Add cached fonts to Vfonts_in_cache.
4628 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
4630 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
4632 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
4634 (FONT_H): Define after FRAME_H.
4635 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
4636 Update dependencies.
4638 * w32term.c: Remove leftover declaration of keyboard_codepage.
4640 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4642 * makefile.w32-in (FONT_H): Add $(FRAME_H).
4643 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
4644 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
4645 (GLOBAL_SOURCES): Add cygw32.c.
4646 ($(BLD)/unexw32.$(O)):
4648 ($(BLD)/w32console.$(O)):
4649 ($(BLD)/w32fns.$(O)):
4650 ($(BLD)/w32heap.$(O)):
4651 ($(BLD)/w32menu.$(O)):
4652 ($(BLD)/w32proc.$(O)): Add w32common.h.
4654 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
4656 (x_to_w32_color): Don't modify the argument, modify a copy instead.
4658 2012-10-08 Daniel Colascione <dancol@dancol.org>
4660 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
4661 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
4662 accidental message numbering hole. Change other messages to
4665 * w32select.h (HAVE_W32SELECT): Remove.
4667 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
4668 w32common.h instead of w32heap.h.
4670 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
4671 (get_allocation_unit, get_processor_type, get_w32_major_version)
4672 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4673 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4674 (OS_NT, os_subtype, cache_system_info): Move declarations to
4677 * w32heap.c: Include w32common.h.
4678 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
4679 (w32_minor_version, w32_build_number, w32_subtype):
4680 Remove duplicate definitions.
4682 * w32fns.c: Include w32common.h; include w32heap.h only in
4685 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
4686 Use `report_file_error' instead of `error' in order to better
4687 inform users of what went wrong. Increase NTGUI_UNICODE file
4688 dialog box file name length to 32k, the maximum allowed by the NT
4691 * w32common.h: New file.
4692 (ROUND_UP, ROUND_DOWN, get_page_size)
4693 (get_allocation_unit, get_processor_type, get_w32_major_version)
4694 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4695 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4696 (OS_NT, os_subtype, cache_system_info): Move here.
4698 * unexw32.c, unexcw.c: Include w32common.h.
4700 * emacs.c (main): Use (defined (WINDOWSNT) || defined
4701 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
4702 to call syms_of_w32select.
4704 * cygw32.h: Remove obsolete EXFUN declarations.
4706 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
4708 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
4709 of w32inevt.o from SOME_MACHINE_OBJECTS.
4711 2012-10-08 Daniel Colascione <dancol@dancol.org>
4713 * image.c: Permanent fix for JPEG compilation issue --- limit
4714 jpeglib `boolean' redefinition to Cygwin builds.
4716 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4718 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
4720 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
4723 2012-10-08 Daniel Colascione <dancol@dancol.org>
4725 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4726 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
4727 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
4728 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
4729 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
4730 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4731 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4732 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4733 now a supported configuration.
4735 * Makefile.in: consolidate image variables into LIBIMAGE; add
4736 W32_OBJ and W32_LIBS. Compile new files.
4739 (_DebPrint) declare tracing facility for W32 debugging. We need
4740 to unify tracing later.
4742 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4743 unconditional use of W32 Unicode functions. Cygwin runs only on
4744 100% Unicode operating systems.
4746 * cygw32.c: New file. Define Cygwin-specific facilities.
4747 (Fcygwin_convert_path_to_windows)
4748 (Fcygwin_convert_path_from_windows): New user functions for
4749 accessing Cygwin path-munging routines.
4751 * cygw32.h: New file.
4752 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4753 UTF-16LE strings temporarily inside non-Lisp-visible string
4756 (w32_strerror): Just what it says on the tin.
4758 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4759 also run for Cygwin; both systems have the same problem with using
4760 GUI facilities in a forked child. Also call syms_of_cygw32,
4761 syms_of_w32select in correct places.
4763 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4764 needs fork-then-exec for daemon launching.
4766 * font.h: Include frame.h.
4768 * image.c: Use the image library cache machinery only when we're
4769 compiling for native WINDOWSNT; Cygwin can use shared libraries
4770 like any other Unixlike system.
4772 * keyboard.c: Clarify a comment regarding the input loop.
4774 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4775 functions directly instead of trying to detect at runtime that our
4776 host operating system supports them. We make this change for two
4777 reasons: Cygwin lacks support for the multibyte character
4778 conversion functions used by the legacy menu code, and Cygwin
4779 never needs to rely on non-Unicode APIs.
4781 * unexw32.c (hinst): Declare extern.
4783 * w32.c: Change header order;
4784 (w32_strerror): Move to w32fns.c because we need it for
4785 non-WINDOWSNT builds.
4787 * w32.h: Add #error macro to make sure we don't include w32.h for
4788 Cygwin builds. Remove w32select declarations.
4790 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4791 w32fns.c. w32console.c is WINDOWSNT-only.
4793 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4794 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4796 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4797 (w32_major_version, w32_minor_version, w32_build_number)
4798 (os_subtype, sound_type): Define here
4799 (w32_defined_color): Make color parameter const for consistency
4800 with other _defined_color functions.
4801 (w32_createwindow): Unconditionally call w32_init_class instead of
4802 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4803 through the code is complex and unnecessary because class
4804 registration is practically free.
4805 (w32_name_of_message): New EMACSDEBUG-only function.
4806 (Fset_message_beep): Move here
4807 (Fx_open_connection): Require that the display name for Windows be
4808 "w32" for consistency, emacsclient disambiguation, and maybe, one
4809 day, multi-window-system support.
4810 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4811 Cygwin files for W32 GUI facilities, since these clearly don't
4812 expect Cygwin names.
4813 (_DebPrint): Define.
4814 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4815 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4816 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4817 (w32_last_error): Remove.
4819 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4821 * w32heap.c (syspage_mask): Declare here.
4822 (cache_system_info): Remove.
4824 * w32inevt.c (faked_key): Define globally, not statically.
4825 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4826 (w32_console_toggle_lock_key): Move to w32fns.c.
4828 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4830 * w32proc.c (_DebPrint): Move to w32fns.c.
4831 * w32select.c: Include string.h, stdio.h for Cygwin.
4832 * w32select.h: New File.
4834 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4836 (w32_message_fd): New variable. Under Cygwin, holds the file
4837 descriptor the system used to tell us about pending thread
4840 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4841 that prevented compilation under non-WINDOWSNT systems.
4843 (w32_initialize): Open /dev/windows and assign it to
4844 w32_message_fd. Provide w32 feature.
4846 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4847 (WM_EMACS_INPUT_READY): add.
4848 (prepend_msg, w32_message_fd): Declare globally.
4851 (keyboard_handle): Use only when WINDOWSNT.
4852 (notify_msg_ready): New function. Posts a message to the main
4853 thread's message queue under CYGWIN, which wakes up the main
4854 thread from select(2) by making the /dev/windows file descriptor
4855 ready. Under WINDOWSNT, it sets an event the same way the old
4858 (post, prepend_msg): Actually call notify_msg_ready instead of
4859 setting the input event directly.
4861 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4863 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4864 but it still has blocs in it, don't return it to the system,
4865 instead of aborting. (Bug#12402)
4867 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4869 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4871 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4872 MAC_OS_X_VERSION_10_6.
4873 (syms_of_nsterm): Remove comment about Panther and above for
4875 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
4876 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
4877 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4879 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4880 MAC_OS_X_VERSION_10_4.
4882 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4883 MAC_OS_X_VERSION_10_2.
4885 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4887 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4888 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4890 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4891 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4892 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4893 Remove ns_in_resize check.
4894 (ns_clear_frame_area): Remove resize handle code.
4896 * nsfns.m (ns_in_resize): Remove.
4897 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4898 Remove ns_in_resize check.
4900 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4902 Improve sys_siglist detection.
4903 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4904 defined as a macro, as is done in Solaris.
4905 (sys_siglist_entries): New macro.
4906 (save_strsignal): Use it.
4907 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4908 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4910 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4912 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4913 fullscreen/Fullscreen.
4915 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4916 tobar_height is new.
4918 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4919 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4920 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4921 (windowDidResize:): Check for correct window if old style fullscreen.
4922 Capitalize word in comment. Remove incorrect comment.
4923 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4924 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4925 error in drawing background.
4926 (toggleFullScreen:): Remove comment. Rearrange calls.
4927 Set toolbar values to zero, save old height in tobar_height.
4928 Restore tool bar height when leaving fullscreen.
4929 (canBecomeMainWindow): New function.
4931 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4933 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4935 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4937 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4939 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4940 that time stamps of directories could also be changed.
4941 Don't request the too broad GENERIC_WRITE, only the more restrictive
4942 FILE_WRITE_ATTRIBUTES access rights.
4944 * fileio.c (Fset_file_times): Special-case ignoring errors for
4945 directories only on MSDOS, not on MS-Windows.
4947 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4949 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4951 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4953 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4954 see whether CreateFile failed.
4956 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4958 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4959 to avoid similar races.
4960 * keyboard.c (pending_signals): Now bool, not int.
4962 Port timers to OpenBSD, plus check for timer failures.
4963 OpenBSD problem reported by Han Boetes.
4964 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4966 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4967 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4968 like OpenBSD, which has timer_settime but does not declare it.
4969 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4970 whether to use itimerspec-related primitives. All uses of
4971 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4973 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4975 * profiler.c (handle_profiler_signal): Fix a malloc race
4976 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4978 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4980 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4982 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4984 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4985 consistent with the change in return value of 'safe_strsignal'.
4987 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4989 Prefer plain 'static' to 'static inline' (Bug#12541).
4990 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4991 (bidi_set_sor_type, bidi_push_embedding_level)
4992 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
4993 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
4994 (bidi_cache_search, bidi_cache_ensure_space)
4995 (bidi_cache_iterator_state, bidi_cache_find)
4996 (bidi_peek_at_next_level, bidi_set_paragraph_end)
4997 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4998 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4999 Now 'static', not 'static inline'.
5001 Count overruns when profiling; change units to ns.
5002 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
5003 Give extra weight to samples after overruns, to attempt to count
5004 the time more accurately.
5005 (setup_cpu_timer): Change sampling interval units from ms to ns, since
5006 the underlying primitives nominally do ns.
5007 (Fprofiler_cpu_start): Document the change. Mention that
5008 the sampling intervals are only approximate.
5010 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5012 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
5014 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
5015 case for the special 0 coding-system.
5017 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
5018 (Fmake_overlay): Remove redundant tests.
5019 (fix_start_end_in_overlays): Remove redundant recentering.
5021 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
5023 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
5024 Update dependencies.
5026 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5028 Fix a malloc race condition involving strsignal.
5029 A signal can arrive in the middle of a malloc, and Emacs's signal
5030 handler can invoke strsignal, which can invoke malloc, which is
5031 not portable. This race condition bug makes Emacs hang on GNU/Linux.
5032 Fix it by altering the signal handler so that it does not invoke
5034 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
5035 * process.c (status_message): Use const pointer, in case strsignal
5036 is #defined to safe_strsignal.
5037 * sysdep.c (sys_siglist, init_signals): Always define and
5038 initialize a substitute sys_siglist if the system does not define
5039 one, even if HAVE_STRSIGNAL.
5040 (safe_strsignal): Rename from strsignal. Always define,
5041 using sys_siglist. Return a const pointer.
5042 * syssignal.h (safe_strsignal): New decl.
5043 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
5045 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5047 * w32proc.c (timer_loop): Fix code that waits for timer
5048 expiration, to avoid high CPU usage.
5050 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
5052 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
5053 (sweep_weak_table): Remove redundant prototypes.
5055 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
5057 * emacs.c: Move the inclusion of TERM_HEADER after including
5058 windows.h on WINDOWSNT. This avoids compilation problems with
5061 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5063 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
5064 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
5065 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
5066 as the previous version used 'void *'.
5068 * ralloc.c (ROUNDUP): Fix last change.
5069 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
5072 * w32proc.c <disable_itimers>: New static flag.
5073 (init_timers): Initialize it to zero, after creating the critical
5074 sections used by the timer threads.
5075 (term_timers): Set to 1 before deleting the critical sections.
5076 (getitimer, setitimer): If disable_itimers is non-zero, return an
5077 error indication without doing anything. Reported by Fabrice
5078 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
5079 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
5081 [!HAVE_SETITIMER]: Behave as the previous version that didn't
5084 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
5085 term_ntproc after all the other bookkeeping, to get timers working
5086 as long as possible.
5088 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5090 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.

5094 Prefer plain 'static' to 'static inline' (Bug#12541).
5095 With static functions, modern compilers inline pretty well by
5096 themselves; advice from programmers often hurts as much as it helps.
5097 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
5098 this change shrinks the text size of the Emacs executable by 1.1%
5099 without affecting CPU significantly in my benchmark.

5398 for consistency with other handlers.
5399 (setup_cpu_timer): New function, with much of what used to be in

5403 monotonic clocks, to the old realtime clock. Use make_timeval
5404 to round more-correctly when falling back to setitimer.
5405 (Fprofiler_cpu_start): Use it.
5406 (Fprofiler_cpu_stop): Prefer timer_settime if available.
5407 Don't assume that passing NULL as the 2nd argument of setitimer

5410 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
5411 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
5412 non-fatal signal handlers. Ignore SIGPROF on startup.

5531 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.
5532 (syms_of_emacs) [WINDOWSNT] <Vlibrary_cache>: Initialize and staticpro.
5533 (Fdump_emacs): Reset Vlibrary_cache and image_types.
5535 * w32.c (Vlibrary_cache): Do not define; moved to emacs.c
5536 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
5538 * w32.h (Vlibrary_cache): Do not declare.
5540 2012-09-25 Eli Zaretskii <eliz@gnu.org>
5542 * w32proc.c (sys_signal): Handle all signals defined by the
5543 MS-Windows runtime, not just SIGCHLD. Actually install the signal
5544 handlers for signals supported by Windows. Don't override
5545 term_ntproc as the handler for SIGABRT.
5546 (sigaction): Rewrite to call sys_signal instead of duplicating its
5548 (sys_kill): Improve commentary.
5550 * w32.c (term_ntproc): Accept (and ignore) one argument, for
5551 consistency with a signature of a signal handler. All callers
5553 (init_ntproc): Accept an argument DUMPING. If dumping, don't
5554 install term_ntproc as a signal handler for SIGABRT, as that
5555 should be done by the dumped Emacs.
5557 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
5559 * w32select.c (term_w32select): Protect against repeated
5560 invocation by setting clipboard_owner to NULL after calling
5563 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
5564 and term_ntproc to their modified signatures.
5566 * character.c (char_string, string_char): Remove calls to
5567 MAYBE_UNIFY_CHAR. See the discussion starting at
5568 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
5571 2012-09-25 Chong Yidong <cyd@gnu.org>
5573 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
5575 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
5577 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
5578 when encountering an unknown bytecode.
5580 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
5582 image.c, indent.c: Use bool for booleans.
5583 * dispextern.h (struct image_type): Members valid_p, load, init
5584 now return bool, not int. All uses changed.
5585 * image.c: Omit unnecessary static decls.
5586 (x_create_bitmap_mask, x_build_heuristic_mask):
5587 Return void, not int, since callers don't care about the return value.

5616 Use bool for booleans.
5618 2012-09-24 Chong Yidong <cyd@gnu.org>
5620 * chartab.c (Fset_char_table_default): Obsolete function removed.
5622 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5624 Move pid_t related decls out of lisp.h.
5625 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
5626 (interruptible_wait_for_termination):
5627 Move these decls from lisp.h to syswait.h, since they use pid_t.
5628 Needed on FreeBSD; see Herbert J. Skuhra in
5629 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
5630 * callproc.c: Include syswait.h.

5647 * nsmenu.m (ns_update_menubar):
5648 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
5649 * xfns.c (Fx_show_tip) [USE_GTK]:
5650 Use bool for boolean.
5651 * gtkutil.c (xg_update_frame_menubar):
5652 * xmenu.c (update_frame_menubar):
5653 Return void, not int, since caller ignores return value.
5654 * gtkutil.c (xg_change_toolbar_position):
5657 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5659 * makefile.w32-in (BLOCKINPUT_H): Remove.

5676 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5678 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5679 fatal_error_backtrace.
5681 * w32proc.c (sys_kill): Undo last change: don't do anything when
5682 invoked to deliver SIGABRT to our own process. This is now
5683 handled by emacs_raise.
5685 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5687 * w32term.c (w32_read_socket): Remove leftover reference to
5688 interrupt_input_pending.
5690 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5692 Do not use SA_NODEFER.
5693 Problem reported by Dani Moncayo in
5694 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5696 * sysdep.c (emacs_abort): Do not reset signal handler.
5697 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5698 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5699 wanted even on POSIXish hosts, and it doesn't work on Windows.
5701 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5703 * xterm.c (x_term_init): Call fixup_locale before and after calling
5704 gtk_init (Bug#12392).
5706 2012-09-23 Chong Yidong <cyd@gnu.org>
5708 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5709 Vdynamic_library_alist.
5711 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5712 (Fgnutls_available_p): Caller changed.
5714 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5715 (Flibxml_parse_xml_region): Likewise.
5717 * dispextern.h (struct image_type): Remove arg from init function.
5719 * image.c (Finit_image_library, lookup_image_type)
5720 (define_image_type): Remove now-unneeded second arg.
5721 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5722 (init_tiff_functions, init_gif_functions, init_svg_functions):
5723 Arglist and w32_delayed_load calling convention changed.
5724 (gs_type): Remove init_gs_functions; there is no such function.
5725 (valid_image_p, make_image): Fix caller to lookup_image_type.
5727 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5729 Simplify and avoid signal-handling races (Bug#12471).
5731 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5732 Avoid recursive loop if there's a fatal error in the function itself.
5733 * atimer.c (pending_atimers):
5734 * blockinput.h: Don't include "atimer.h"; no longer needed.
5735 (interrupt_input_pending): Remove. All uses removed.
5736 pending_signals now counts both atimers and ordinary interrupts.
5737 This is less racy than having three separate pending-signal flags.
5738 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5740 Rename from their upper-case counterparts BLOCK_INPUT,
5741 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5742 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5743 This makes it easier to access volatile variables more accurately.
5744 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5745 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5746 that's more reliable if the code is buggy and sets
5747 interrupt_input_blocked to a negative value. All uses changed.
5748 * atimer.c (deliver_alarm_signal):
5749 Remove. No need to deliver this to the parent; any thread can
5750 handle this signal now. All uses replaced by underlying handler.
5751 * atimer.c (turn_on_atimers):
5752 * dispnew.c (handle_window_change_signal):
5753 * emacs.c (handle_danger_signal):
5754 * keyboard.c (kbd_buffer_get_event):
5755 Don't reestablish signal handler; not needed with sigaction.
5756 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5758 Rework to avoid unnecessary accesses to volatile variables.
5759 (UNBLOCK_INPUT_TO): Now a function.
5760 (totally_unblock_input, unblock_input): New decls.
5761 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5762 (init_data): Remove. Necessary stuff now done in init_signal.
5763 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5764 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5765 (fatal_error_code): Remove; no longer needed.
5766 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5767 it doesn't always backtrace. All uses changed. No need to reset
5768 signal to default, since sigaction and/or die does that for us now.
5769 Use emacs_raise (FOO), not kill (getpid (), FOO).
5770 (main): Check more-accurately whether we're dumping.
5771 Move fatal-error setup to sysdep.c
5772 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5773 * gtkutil.c (xg_get_file_name, xg_get_font):
5774 Remove no-longer-needed signal-mask manipulation.
5775 * keyboard.c, process.c (POLL_FOR_INPUT):
5776 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5777 * keyboard.c (read_avail_input): Remove.
5778 All uses replaced by gobble_input.
5779 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5780 (kbd_buffer_store_event_hold, gobble_input):
5781 (record_asynch_buffer_change) [USABLE_SIGIO]:
5782 (store_user_signal_events):
5783 No need to mess with signal mask.
5784 (gobble_input): If blocking input and there are terminals, simply
5785 set pending_signals to 1 and return. All hooks changed to not
5786 worry about whether input is blocked.
5787 (process_pending_signals): Clear pending_signals before processing
5788 them, in case a signal comes in while we're processing.
5789 By convention callers now test pending_signals before calling us.
5790 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5791 New functions, to support changes to blockinput.h.
5792 (handle_input_available_signal): Now extern.
5793 (reinvoke_input_signal): Remove. All uses replaced by
5795 (quit_count): Now volatile, since a signal handler uses it.
5796 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5797 All callers changed. Block SIGINT only if not already blocked.
5798 Clear sigmask reliably, even if Fsignal returns, which it can.
5799 Omit unnecessary accesses to volatile var.
5800 (quit_throw_to_read_char): No need to restore sigmask.
5801 * keyboard.c (gobble_input, handle_user_signal):
5802 * process.c (wait_reading_process_output):
5803 Call signal-handling code rather than killing ourselves.
5804 * lisp.h: Include <float.h>, for...
5805 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5806 (pending_signals): Now volatile.
5807 (syms_of_data): Now const if IEEE floating point.
5808 (handle_input_available_signal) [USABLE_SIGIO]:
5809 (terminate_due_to_signal, record_child_status_change): New decls.
5810 * process.c (create_process): Avoid disaster if memory is exhausted
5811 while we're processing a vfork, by tightening the critical section
5813 (send_process_frame, process_sent_to, handle_pipe_signal)
5814 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5816 (send_process): No need for setjmp/longjmp any more, since the
5817 SIGPIPE stuff is now gone. Instead, report an error if errno
5819 (record_child_status_change): Now extern. PID and W are now args.
5820 Return void, not bool. All callers changed.
5821 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5822 Remove. All uses removed. This bug should be fixed now in a
5824 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5825 and record the child status change directly. This avoids the
5826 need to futz with the signal mask.
5827 (process_fatal_action): Move here from emacs.c.
5828 (emacs_sigaction_flags): New function, containing
5829 much of what used to be in emacs_sigaction_init.
5830 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5831 caught by emacs, to make races less likely.
5832 (deliver_process_signal): Rename from handle_on_main_thread.
5834 (BACKTRACE_LIMIT_MAX): Now at top level.
5835 (thread_backtrace_buffer, threadback_backtrace_pointers):
5837 (deliver_thread_signal, deliver_fatal_thread_signal):
5838 New functions, for more-accurate delivery of thread-specific signals.
5839 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5840 (deliver_arith_signal): Handle in this thread, not
5841 in the main thread, since it's triggered by this thread.
5842 (maybe_fatal_sig): New function.
5843 (init_signals): New arg DUMPING so that we can be more accurate
5844 about whether we're dumping. Caller changed.
5845 Treat thread-specific signals differently from process-general signals.
5846 Block all signals while handling fatal error; that's safer.
5847 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5849 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5850 Ignore SIGPIPE unless batch.
5851 (emacs_backtrace): Output backtrace for the appropriate thread,
5852 which is not necessarily the main thread.
5853 * syssignal.h: Include <stdbool.h>.
5854 (emacs_raise): New macro.
5855 * xterm.c (x_connection_signal): Remove; no longer needed
5856 now that we use sigaction.
5857 (x_connection_closed): No need to mess with sigmask now.
5858 (x_initialize): No need to reset SIGPIPE handler here, since
5859 init_signals does this for us now.
5861 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5863 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5864 background rect may be larger (Bug#12245).
5866 2012-09-23 Chong Yidong <cyd@gnu.org>
5868 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5870 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5872 * .gdbinit: Just stop at fatal_error_backtrace.
5873 See Stefan Monnier's request in
5874 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5875 Remove no-longer-used query of system type.
5877 2012-09-22 Chong Yidong <cyd@gnu.org>
5879 * search.c (Freplace_match): Doc fix (Bug#12325).
5881 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5883 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5884 (Fline_end_position): Doc fix.
5886 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5888 2012-09-22 Chong Yidong <cyd@gnu.org>
5890 * dispextern.h (struct image_type): Add new slot, storing a type
5891 initialization function.
5893 * image.c (define_image_type): Call the image initializer function
5894 if it is defined. Arguments and return value changed.
5895 (valid_image_p, make_image): Callers changed.
5896 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5897 (gif_type, imagemagick_type, svg_type, gs_type):
5898 Add initialization functions.
5899 (Finit_image_library): Call lookup_image_type.
5900 (CHECK_LIB_AVAILABLE): Macro deleted.
5901 (lookup_image_type): Call define_image_type here, rather than via
5902 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5903 (syms_of_image): Move define_image_type calls for xbm_type and
5904 pbm_type to lookup_image_type.
5906 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5908 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5909 'idle_timers' from here ...
5910 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5911 lists, to avoid infloops when the timer does something stupid,
5912 like reinvoke itself with the same or smaller time-out.
5915 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5917 * window.c (Fsplit_window_internal): Handle only Qt value of
5918 Vwindow_combination_limit separately.
5919 (Qtemp_buffer_resize): New symbol.
5920 (Vwindow_combination_limit): New default value.
5923 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5925 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5926 the new overlay string. (Bug#10159)
5928 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5930 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5931 or that fprintf is async-signal-safe. POSIX doesn't require
5934 2012-09-22 Chong Yidong <cyd@gnu.org>
5936 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5939 2012-09-22 Kenichi Handa <handa@gnu.org>
5941 * composite.c (composition_reseat_it): Handle the case that a
5942 grapheme cluster is not covered by a single font (Bug#12352).
5944 2012-09-21 Chong Yidong <cyd@gnu.org>
5946 * image.c (define_image_type): Avoid adding duplicate types to
5947 image_types (Bug#12463). Suggested by Jörg Walter.
5949 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5951 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5952 (print_load_command_name): Add case LC_DATA_IN_CODE.
5953 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5955 2012-09-21 Glenn Morris <rgm@gnu.org>
5957 * eval.c (Frun_hook_with_args_until_success)
5958 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5960 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5962 * fileio.c (Ffile_selinux_context): Only call freecon when
5963 lgetfilecon succeeded.
5964 (Fset_file_selinux_context): Likewise. (Bug#12444)
5966 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5968 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5969 reordering, locate the cursor by calling set_cursor_from_row; if
5970 that fails, clear the desired glyph matrix before returning a
5971 failure indication to the caller. Fixes leaving garbled display
5972 when fast scrolling with a down-key. (Bug#12403)
5973 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5974 scrolling through multibyte text.
5976 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5978 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5979 calling mark_vectorlike since that's the one that marks the window.
5980 (mark_discard_killed_buffers): Mark the final cdr.
5981 * window.h (struct window): Move prev/next_buffers to the
5982 non-standard fields.
5983 * window.c (make_window): Initialize prev/next_buffers manually.
5985 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5987 Omit unused arg EXPECTED from socket hooks.
5988 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5989 * nsterm.m (ns_term_init):
5990 * termhooks.h (struct terminal.read_socket_hook):
5991 * w32inevt.c (w32_console_read_socket):
5992 * w32term.c (w32_read_socket):
5993 * xterm.c (XTread_socket):
5994 Omit unused arg EXPECTED. All callers changed.
5995 (store_user_signal_events): Return void, not int, since callers no
5996 longer care about the return value. All uses changed.
5998 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
6000 * w32gui.h (XParseGeometry): Do not declare.
6002 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
6004 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
6005 Ignore 'expected'. See Eli Zaretskii in
6006 <http://bugs.gnu.org/12471#8> (last line).
6008 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
6009 (XParseGeometry): Now static. Substitute extremal values for
6010 values that are out of range.
6012 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
6014 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
6016 * nsfns.m (XParseGeometry): Remove.
6017 (Fx_create_frame): Call x_set_offset to correctly interpret
6018 top_pos in geometry.
6020 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
6021 (Fx_parse_geometry): If there is a space in string, call
6022 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
6024 2012-09-17 Eli Zaretskii <eliz@gnu.org>
6026 * search.c (scan_buffer): Use character positions in calls to
6027 region_cache_forward and region_cache_backward, not byte
6028 positions. (Bug#12196)
6030 * w32term.c (w32_read_socket): Set pending_signals to 1, like
6031 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
6033 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
6034 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
6035 emacs_blocked_malloc, now deleted.
6037 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
6039 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
6040 The workaround was for improving performance on Solaris 2.4, but
6041 is getting in the way now. Emacs will still work if someone is
6042 still running Solaris 2.4 in a museum somewhere; Sun dropped
6043 support for Solaris 2.4 in 2003.
6044 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
6045 * process.c (create_process) [HAVE_WORKING_VFORK]:
6046 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
6047 since Emacs no longer uses vfork on that platform.
6049 2012-09-17 Glenn Morris <rgm@gnu.org>
6051 * emacs.c: Use COPYRIGHT.
6053 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
6055 Remove configure's --without-sync-input option (Bug#12450).
6056 When auditing signal-handling in preparation for cleaning it up,
6057 I found that SYNC_INPUT has race conditions and would be a real
6058 pain to fix. Since it's an undocumented and deprecated
6059 configure-time option, now seems like a good time to remove it.
6060 Also see <http://bugs.gnu.org/11080#16>.
6061 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
6062 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
6063 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6064 (malloc_hysteresis):
6065 (check_depth) [XMALLOC_OVERRUN_CHECK]:
6066 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
6067 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
6068 (dont_register_blocks, bytes_used_when_reconsidered)
6069 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
6070 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
6071 [!SYSTEM_MALLOC && !SYNC_INPUT]:
6072 Remove. All uses removed.
6073 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
6074 implementation, one that depends on whether the new macro
6075 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
6077 * atimer.c (run_timers, handle_alarm_signal):
6078 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
6079 (handle_async_input, process_pending_signals)
6080 (handle_input_available_signal, init_keyboard):
6081 * nsterm.m (ns_read_socket):
6082 * process.c (wait_reading_process_output):
6083 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
6084 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
6086 * xterm.c (XTread_socket):
6088 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
6089 * eval.c (handling_signal): Remove. All uses removed.
6090 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
6091 All uses replaced with the SYNC_INPUT version.
6092 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
6094 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6097 * font.c (Ffont_shape_gstring): Remove unused local.
6099 2012-09-16 Glenn Morris <rgm@gnu.org>
6101 * Makefile.in (clean): No longer run nextstep's clean.
6103 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
6105 (ns-app): Move here from ns.mk, and simplify.
6106 (clean): Simplify nextstep entry.
6107 * ns.mk: Remove file.
6109 2012-09-17 Kenichi Handa <handa@gnu.org>
6111 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
6112 not covert the last few charactes.
6114 2012-09-16 Kenichi Handa <handa@gnu.org>
6116 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
6117 here, but just check the validity of glyphs in the glyph-string.
6119 2012-09-16 Martin Rudalics <rudalics@gmx.at>
6121 * window.c (Fwindow_parameter, Fset_window_parameter):
6122 Accept any window as argument (Bug#12452).
6124 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
6126 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
6127 to ns_term_init to avoid memory leak.
6129 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
6130 explicit retain/release.
6131 (ns_term_init): Only allow one display. Initialize outerpool and
6134 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6136 Port _setjmp fix to POSIXish hosts as well as Microsoft.
6137 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
6138 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
6139 the Microsoft problem in a different way, by altering ../nt/config.nt.
6141 2012-09-15 Eli Zaretskii <eliz@gnu.org>
6156 * w16select.c: Remove inclusion of setjmp.h, as it is now included
6157 by lisp.h. This completes removal of setjmp.h inclusion
6158 erroneously announced in the previous commit. (Bug#12446)
6160 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
6163 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
6164 not defined as a macro. The latter happens on MS-Windows.
6167 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6169 Port better to POSIX hosts lacking _setjmp (Bug#12446).
6170 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
6171 Some instances of '#include <setjmp.h>' removed, if the
6172 only reason for the instance was because "lisp.h" was included.
6173 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
6174 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
6175 and _longjmp with the new symbols. Emacs already uses _setjmp if
6176 available, so this change affects only POSIXish hosts that have
6177 sigsetjmp but not _setjmp, such as some versions of Solaris and
6178 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
6179 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
6180 (png_load_body) [HAVE_PNG]:
6181 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
6182 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
6183 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
6184 since PNG requires jmp_buf. This is the only exception to the
6185 general rule that we now use sys_setjmp and sys_longjmp.
6186 This exception is OK since this code does not change the signal
6187 mask or longjmp out of a signal handler.
6189 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
6191 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6192 Include "syssignal.h", for 'main_thread'.
6194 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
6196 Avoid out-of-range marker position (Bug#12426).
6197 * insdel.c (replace_range, replace_range_2):
6198 Adjust markers before overlays, as suggested by comments.
6199 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
6200 Remove redundant check before calling offset_intervals.
6202 2012-09-14 Martin Rudalics <rudalics@gmx.at>
6204 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
6205 current buffer (Bug#12387).
6207 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
6209 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
6211 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6213 Use a more backwards-compatible timer format (Bug#12430).
6214 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
6215 vector element, not from the 4th, since PSECS is now at the end.
6216 (Fcurrent_idle_time): Doc fix.
6218 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
6220 Function to mark objects and remove killed buffers at once.
6221 * alloc.c (discard_killed_buffers): Rename to ...
6222 (mark_discard_killed buffers) ... new name. Add marking
6223 of remaining objects. Fix comment. Adjust users.
6224 (mark_object): Do not touch frame buffer lists here.
6225 * frame.c (delete_frame): Reset frame buffer lists here.
6227 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6229 Better workaround for GNOME bug when --enable-gcc-warnings.
6230 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
6231 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
6232 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
6234 Simplify SIGIO usage (Bug#12408).
6235 The code that dealt with SIGIO was crufty and confusing, e.g., it
6236 played tricks like "#undef SIGIO" but these tricks were not used
6237 consistently. Simplify mostly by not #undeffing standard symbols,
6238 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
6239 or not as we please) rather than "defined SIGIO" (standard symbol
6240 that we probably shouldn't #undef).
6241 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
6242 Modules that need it can include it.
6243 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
6244 * dispextern.h (ignore_sigio): New decl.
6245 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
6246 unconditionally, since it's now a no-op if !USABLE_SIGIO.
6247 * emacs.c (shut_down_emacs):
6248 * keyboard.c (kbd_buffer_store_event_hold):
6249 Use ignore_sigio rather than invoking 'signal' directly.
6250 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
6252 (FIONREAD, SIGIO): Do not #undef.
6253 (tty_read_avail_input): Use #error rather than a syntax error.
6254 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
6255 for I_PIPE, used by SETUP_SLAVE_PTY.
6256 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
6257 * sysdep.c (croak): Remove; no longer needed. This bit of
6258 temporary code, with Fred N. Fish's comment that it's temporary,
6259 has been in Emacs since at least 1992!
6260 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
6261 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
6262 * syssignal.h (croak): Remove decl.
6263 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
6264 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
6265 now that we're termios-only.
6266 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
6267 * term.c (dissociate_if_controlling_tty): Use #error rather than
6270 Work around GCC and GNOME bugs when --enable-gcc-warnings.
6271 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
6272 to work around GNOME bug 683906.
6273 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
6274 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
6275 This works around GCC bug 54561.
6277 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6279 More fixes for 'volatile' and setjmp/longjmp.
6280 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
6281 * image.c (struct png_load_context) [HAVE_PNG]: New type.
6282 (png_load_body) [HAVE_PNG]:
6283 (jpeg_load_body) [HAVE_JPEG]:
6284 New function, with most of the old parent function's body.
6285 (png_load) [HAVE_PNG]:
6286 (jpeg_load) [HAVE_JPEG]:
6287 Invoke the new function, to avoid longjmp munging our locals.
6288 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
6289 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
6290 longjmp is passed 2, as the C standard doesn't guarantee this.
6291 Instead, store the failure code into mgr->failure_code.
6293 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6295 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
6296 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
6297 (syms_of_keyboard): Remove support for unread-command-char.
6299 2012-09-12 Eli Zaretskii <eliz@gnu.org>
6301 * w32proc.c (sys_kill): If PID is our process ID and the signal is
6302 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
6303 violation. (Bug#12426)
6305 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6307 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
6309 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6311 * eval.c: Add `inhibit-debugger'.
6312 (Qinhibit_debugger): New symbol.
6313 (call_debugger): Bind it instead of Qdebug_on_error.
6314 (maybe_call_debugger): Test Vinhibit_debugger.
6315 (syms_of_eval): Define inhibit-debugger.
6316 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6317 (syms_of_xdisp): Remove inhibit-debug-on-message.
6319 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6321 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6322 If a nonvolatile local variable is written before a _longjmp to
6323 the frame containing the variable, and is read after the _longjmp,
6324 the value read is indeterminate. Some local variables of type
6325 'struct handler' and 'struct catchtag' are used in this way, so
6326 mark each of their slots as volatile if the slot can be set before
6327 _longjmp and read afterwards.
6328 * lisp.h (struct handler): var and chosen_clause are now volatile.
6329 (struct catchtag): val, next, and pdlcount are now volatile.
6331 * bidi.c (bidi_push_it, bidi_pop_it):
6332 * fns.c (copy_hash_table):
6333 * image.c (define_image_type):
6334 * keyboard.c (kbd_buffer_store_event_hold):
6335 * process.c (Fprocess_send_eof):
6336 * xfaces.c (x_create_gc) [HAVE_NS]:
6337 * xgselect.c (xg_select):
6338 Prefer assignment to memcpy when either will do.
6340 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6341 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6342 time an item is removed. No need to mark this function 'inline';
6343 the compiler knows better than we do.
6345 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6347 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6348 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6349 to change_frame_size (Bug#12388).
6350 (windowDidResize:): Pass YES to updateFrameSize.
6352 * nsterm.h: Add delay parameter to updateFrameSize.
6354 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6356 Discard killed buffers from deleted window and frame objects.
6357 This reduces an amount of references to killed buffers and
6358 helps GC to reclaim them faster.
6359 * alloc.c (discard_killed_buffers): New function.
6360 (mark_object): Use it for deleted windows and frames.
6361 (mark_object): If symbol's value is set up for a killed buffer
6362 or deleted frame, restore its global binding.
6363 * data.c (swap_in_global_binding): Add GC notice.
6364 (swap_in_symval_forwarding): Use convenient set_blv_where.
6365 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6366 * window.h: ... to here.
6368 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6370 Convenient macro to check whether the buffer is live.
6371 * buffer.h (BUFFER_LIVE_P): New macro.
6372 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6373 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6375 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6377 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6378 composition cases (Bug#12364).
6380 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6381 overhang of succeeding glyphs overlapping box cursor.
6383 * w32term.c (x_draw_glyph_string): Likewise.
6385 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6387 Simplify, document, and port floating-point (Bug#12381).
6388 The porting part of this patch fixes bugs on non-IEEE platforms
6389 with frexp, ldexp, logb.
6390 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6392 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6393 support, by removing commented-out code and briefly listing the
6394 C89 functions excluded. The commented-out stuff was confusing
6395 maintenance, e.g., we thought we needed cbrt but it was commented out.
6396 (logb): Remove decl; no longer needed.
6397 (isfinite): New macro, if not already supplied.
6398 (isnan): Don't replace any existing macro.
6399 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6400 are present on all C89 platforms.
6401 (Ffrexp): Do not special-case zero, as frexp does the right thing
6403 (Flogb): Do not use logb, as it doesn't have the desired meaning
6404 on hosts that use non-base-2 floating point. Instead, stick with
6405 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6406 frexp, to avoid getting an unspecified result.
6408 * xdisp.c (Qinhibit_debug_on_message): Now static.
6410 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6412 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6413 NSBezierPath (Bug#12131).
6415 2012-09-10 Chong Yidong <cyd@gnu.org>
6417 * fns.c (Fdelq, Fdelete): Doc fix.
6419 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6421 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6422 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6424 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6426 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6427 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6430 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6432 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6433 left fringe if the window has a left margin. This avoids leaving
6434 traces of the cursor because its leftmost pixel is not drawn over.
6436 * dispnew.c (update_window_line): When the left margin area of a
6437 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6438 that screen line. (Bug#12277)
6440 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6442 Assume C89 or later for math functions (Bug#12381).
6443 This simplifies the code, and makes it a bit smaller and faster,
6444 and (most important) makes it easier to clean up signal handling
6445 since we can stop worring about floating-point exceptions in
6446 library code. That was a problem before C89, but the problem
6447 went away many years ago on all practical Emacs targets.
6448 * data.c, image.c, lread.c, print.c:
6449 Don't include <math.h>; no longer needed.
6450 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6451 might be autoconfigured, as that never happens.
6453 * doprnt.c (DBL_MAX_10_EXP):
6454 * print.c (DBL_DIG):
6455 Remove. C89 or later always defines these.
6456 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6457 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6458 (arith_error, domain_error, domain_error2):
6459 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6460 no longer needed -- we simply return what C returns. All uses removed.
6461 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6463 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6464 Remove. All uses expanded, as these macros are no longer used
6465 more than once and are now more trouble than they're worth.
6466 (Ftan): Use tan, not sin / cos.
6467 (Flogb): Assume C89 frexp.
6468 (fmod_float): Assume C89 fmod.
6469 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6470 (init_floatfns): Remove. All uses removed.
6472 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6474 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6475 compositeToPoint for OSX < 10.6 (Bug#12390).
6477 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6479 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6480 This produces more-accurate results.
6482 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6484 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6485 changes (Bug#12088).
6487 2012-09-08 Chong Yidong <cyd@gnu.org>
6489 * syntax.c (Fstring_to_syntax): Doc fix.
6491 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6493 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6494 in the internal border.
6495 (x_set_window_size): Remove static variables and their usage.
6496 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6497 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6498 Remove fringe/internal border adjustment (Bug#11052).
6499 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6500 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6501 (ns_fix_rect_ibw): Remove.
6502 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6503 (ns_dumpglyphs_box_or_relief): Ditto.
6504 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6506 (ns_dumpglyphs_image): Ditto.
6507 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6509 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6510 their usage. Add fringe_extended_p and its use as in other terms.
6511 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6512 scroll bar was removed.
6513 (updateFrameSize): New function.
6514 (windowDidResize): Move code to updateFrameSize and call it.
6516 * nsterm.h (EmacsView): Add updateFrameSize.
6518 2012-09-07 Chong Yidong <cyd@gnu.org>
6520 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6522 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6524 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6526 More signal-handler cleanup (Bug#12327).
6527 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6528 Problem introduced when merging patches. Noted by Eli Zaretskii in
6529 <http://bugs.gnu.org/12327#67>.
6530 * floatfns.c: Comment fix.
6531 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6532 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6533 and anyway the declaration is harmless even if SIGDANGER is not defined.
6534 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6535 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6536 source files not surprisingly expected syssignal.h to define, or
6537 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6538 Include <sys/ioctl.h>, for FIONREAD.
6539 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6540 This eliminates a problem whereby other files mysteriously had
6541 to include "syssignal.h" before including "systty.h" if they
6542 wanted to use "#ifdef SIGIO".
6544 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6546 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6548 * w32.c (sigemptyset): Empty the set.
6549 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6551 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6553 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6555 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6556 (mark_object): Likewise for frame objects.
6558 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6560 * syssignal.h (handle_on_main_thread): Always declare,
6561 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6562 This ports to platforms without HAVE_PTHREAD.
6564 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6566 Signal-handler cleanup (Bug#12327).
6567 Emacs's signal handlers were written in the old 4.2BSD style with
6568 sigblock and sigmask and so forth, and this led to some
6569 inefficiencies and confusion. Rewrite these to use
6570 pthread_sigmask etc. without copying signal sets around. Also,
6571 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6572 'signal', and instead use functions that do not attempt to take
6573 over the system name space. This patch causes Emacs's text
6574 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6575 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6576 Do not include <signal.h> or "syssignal.h", as these
6577 modules do not use signals.
6578 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6579 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6580 Do not include <signal.h>, as "syssignal.h" does that for us now.
6581 * atimer.c (sigmask_atimers): New function.
6582 (block_atimers, unblock_atimers): New functions,
6583 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6585 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6586 no longer needed here.
6587 * emacs.c (main): Inspect existing signal handler with sigaction,
6588 so that there's no need to block and unblock SIGHUP.
6589 * sysdep.c (struct save_signal): New member 'action', replacing
6590 old member 'handler'.
6591 (save_signal_handlers, restore_signal_handlers):
6592 Use sigaction instead of 'signal' to save and restore.
6593 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6594 New function. All users of 'signal' modified to use set_sighandler
6595 if they're writeonly, and to use sys_signal if they're read+write.
6596 (emacs_sigaction_init, forwarded_signal): New functions.
6597 (sys_signal): Remove. All uses replaced by calls to sigaction
6598 and emacs_sigaction_init, or by direct calls to 'signal'.
6599 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6600 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6601 all uses replaced by pthread_sigmask etc. calls.
6602 * syssignal.h: Include <signal.h>.
6603 (emacs_sigaction_init, forwarded_signal): New decls.
6604 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6605 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6606 (sigmask, sys_sigmask): Remove; no longer needed.
6607 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6608 (sigblock, sigunblock, sigfree):
6609 (sigsetmask) [!defined sigsetmask]:
6610 Remove. All uses replaced by pthread_sigmask.
6611 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6612 no longer need to be replaced, and its typical old uses
6613 are now done via emacs_sigaction_init and sigaction.
6614 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6615 (sys_sigdel): Remove; unused.
6616 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6618 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6620 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6621 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6623 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6625 Explicitly mark buffer_defaults and buffer_local_symbols.
6626 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6627 mark_local_symbols here.
6628 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6629 since special buffers aren't marked here any more.
6630 (allocate_buffer): Chain new buffer with all_buffers here...
6631 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6633 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6634 (syms_of_buffer): Remove staticpro of the above.
6635 (init_buffer_once): Set names for buffer_defaults and
6636 buffer_local_symbols.
6638 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6640 Use bool for booleans in font-related modules.
6641 * font.c (font_intern_prop, font_style_to_value)
6642 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6643 (generate_otf_features, font_check_otf_features, font_check_otf)
6644 (font_match_p, font_list_entities, font_at):
6645 * fontset.c (fontset_id_valid_p, reorder_font_vector
6646 (fontset_find_font, Fset_fontset_font)
6647 (face_suitable_for_char_p) [0]:
6648 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6649 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6650 (m17n_flt_initialized, ftfont_shape_by_flt):
6651 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6652 * nsfont.m (nsfont_draw):
6653 * w32font.c (w32font_draw):
6654 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6655 Use bool for booleans.
6656 * font.h: Adjust to above API changes.
6657 (struct font, struct font_driver, struct font_driver_list):
6658 Use bool for booleans.
6659 (struct font): Remove useless member encoding_type.
6661 * fontset.c, xftfont.c: Omit unnecessary static decls.
6663 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6665 * alloc.c (mark_object): Revert window marking code
6666 since it's unsafe for the Fset_window_configuration.
6668 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6670 Fix race conditions with signal handlers and errno (Bug#12327).
6671 Be more systematic about preserving errno whenever a signal
6672 handler returns, even if it's not in the main thread. Do this by
6673 renaming signal handlers to distinguish between signal delivery
6674 and signal handling. All uses changed.
6675 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6676 * data.c (deliver_arith_signal): Rename from arith_error.
6677 * dispnew.c (deliver_window_change_signal): Rename from
6678 window_change_signal.
6679 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6680 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6681 * keyboard.c (deliver_input_available_signal): Rename from
6682 input_available_signal.
6683 (deliver_user_signal): Rename from handle_user_signal.
6684 (deliver_interrupt_signal): Rename from interrupt_signal.
6685 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6686 (deliver_child_signal): Rename from sigchld_handler.
6687 * atimer.c (handle_alarm_signal):
6688 * data.c (handle_arith_signal):
6689 * dispnew.c (handle_window_change_signal):
6690 * emacs.c (handle_fatal_signal, handle_danger_signal):
6691 * keyboard.c (handle_input_available_signal):
6692 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6693 * process.c (handle_pipe_signal, handle_child_signal):
6694 New functions, with the actual signal-handling code taken from the
6695 original respective signal handlers, sans the sporadic attempts to
6696 preserve errno, since that's now done by handle_on_main_thread.
6697 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6698 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6699 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6701 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6702 Move initialization of main_thread to sysdep.c's init_signals.
6703 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6704 our usage, and simplifies the mainline code.
6705 (record_child_status_change): New static function, as a helper
6706 for handle_child_signal, and with most of the old child handler's
6708 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6709 (handle_child_signal): Use the above.
6710 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6711 Moved here from emacs.c.
6712 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6713 code moved here from emacs.c's main function.
6714 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6715 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6716 This lets callers save and restore errno properly.
6718 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6720 Remove redundant or unused things here and there.
6721 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6722 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6723 * editfns.c (Fcompare_buffer_substrings): Likewise.
6724 * frame.h (struct terminal, struct font_driver_list):
6725 Remove redundant declarations.
6726 * window.h (Qleft, Qright): Likewise.
6728 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6730 Do not mark objects from deleted buffers, windows and frames.
6731 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6732 (mark_object): Likewise for windows and frames.
6734 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6736 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6737 buffer_defaults and buffer_local_symbols as valid objects.
6738 Return special value to denote them.
6740 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6742 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6743 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6744 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6745 (file_name_absolute_p, Fsubstitute_in_file_name):
6746 (check_executable, check_writable, Ffile_accessible_directory_p)
6747 (Fset_file_selinux_context, Fdefault_file_modes)
6748 (Finsert_file_contents, choose_write_coding_system)
6749 (Fwrite_region, build_annotations, a_write, e_write)
6751 * filelock.c (boot_time_initialized, get_boot_time)
6752 (get_boot_time_1, lock_file_1, within_one_second):
6753 * floatfns.c (in_float):
6754 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6755 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6756 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6757 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6758 * window.c (compare_window_configurations):
6759 Use bool for booleans.
6760 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6761 (Fdefault_file_modes): Now mode_t, not int, for modes.
6762 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6763 (internal_delete_file): Now returns void, not a (boolean) int,
6764 since nobody was looking at the return value.
6765 * lisp.h, window.h: Adjust to above API changes.
6767 * xdisp.c (set_message): Simplify and reindent last change.
6769 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6771 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6773 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6775 * eval.c (call_debugger): Make the function non-static so that we
6776 can call it from set_message.
6778 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6779 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6781 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6783 Give more-useful info on a fatal error (Bug#12328).
6784 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6785 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6786 of doing the work ourselves.
6787 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6788 do most of the work.
6789 (fatal_error_backtrace): New function, taken from the guts
6790 of the old fatal_error_signal, but with a new option to output
6792 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6793 info about the signal than just its number.
6794 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6795 * sysdep.c: Include <execinfo.h>
6796 (emacs_backtrace): New function, taken partly from the previous
6797 code of the 'die' function.
6798 (emacs_abort): Call fatal_error_backtrace rather than abort.
6800 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6802 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6803 eager (load-time) macro-expansion.
6804 * lisp.mk (lisp): Add macroexp.
6806 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6808 Simplify redefinition of 'abort' (Bug#12316).
6809 Do not try to redefine the 'abort' function. Instead, redo
6810 the code so that it calls 'emacs_abort' rather than 'abort'.
6811 This removes the need for the NO_ABORT configure-time macro
6812 and makes it easier to change the abort code to do a backtrace.
6813 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6814 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6815 Remove; sysdep.c's emacs_abort now takes its place.
6816 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6817 'abort' changed to use 'emacs_abort'.
6818 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6819 (abort) [!defined abort]: Rename to ...
6820 (emacs_abort): ... new name.
6821 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6822 the place of the old 'abort' in emacs.c.
6823 * w32.c, w32fns.c (abort): Do not #undef.
6824 * w32.c (emacs_abort): Rename from w32_abort.
6826 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6828 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6829 offsets[j].dv, since the y axis of the screen coordinates points
6830 down, while the y axis of the font definition coordinates points
6831 up. This fixes display of Arabic diacritics such as KASRA and
6832 KASRATAN. (Bug#11860)
6834 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6836 Be more systematic about _setjmp vs setjmp.

6841 * process.c (send_process_trap, send_process):
6842 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6843 The underscored versions are up to 30x faster on some hosts.
6844 Formerly, the code used setjmp+longjmp sometimes and
6845 _setjmp+_longjmp at other times, with no particular reason to
6846 prefer setjmp+longjmp.

6887 REDISPLAYING_P when unwinding, instead of saving its previous,
6888 always-false value and then restoring it.
6890 Clean up some extern decls.
6891 Mostly, this hoists extern decls out of .c files and into .h files.
6892 That way, we're more likely to catch errors if the interfaces change.
6893 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6894 declare xg_mark_data.

6919 * xfaces.c: Remove unnecessary static decls.
6920 * xterm.c (updating_frame): Remove decl of nonexistent object.
6922 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
6923 when building globals.h, as the objects that are not built on
6924 this host are not needed to compile C files on this host.

6978 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
6979 more than one grapheme cluster passed to the shaper: compute the
6980 offset adjustment values separately for each cluster. (Bug#11860)
6982 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6983 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6984 about implicit conversions from integer to pointer.
6986 2012-09-01 Daniel Colascione <dancol@dancol.org>
6988 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
6989 system used too early.

7042 window system declarations.
7044 * frame.h: Move common functions here: set_frame_menubar,
7045 x_set_window_size, x_sync, x_get_focus_frame,
7046 x_set_mouse_position, x_set_mouse_pixel_position,
7047 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

7133 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
7134 Add window_closed and button_values. Add void as return value for
7135 add(Button|String|Split). addButton takes int instead of Lisp_Object.

7282 (struct iso_2022_spec, struct coding_system):
7283 Use 'unsigned int : 1' for boolean fields, since there's more than one.
7284 (struct emacs_mule_spec): Remove unused field 'full_support'.
7285 All initializations removed.
7286 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
7288 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7290 Fix spare memory change (Bug#12286).
7291 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
7292 (valid_lisp_object_p): Likewise.
7294 2012-08-27 Martin Rudalics <rudalics@gmx.at>
7296 * window.c (Fset_window_configuration): Record any window's old
7297 buffer if it's replaced (see Bug#8789). If the new current
7298 buffer doesn't appear in the selected window, go to its old
7301 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7303 Special MEM_TYPE_SPARE to denote reserved memory.
7304 * alloc.c (enum mem_type): New memory type.
7305 (refill_memory_reserve): Use new type for spare memory.
7306 This prevents live_cons_p and live_string_p from incorrect
7307 detection of uninitialized objects from spare memory as live.
7309 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
7312 * Makefile.in (.PHONY): versioclean -> versionclean.
7314 Remove unused external symbols.
7315 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
7316 * window.c (Qwindow_valid_p, decode_valid_window):
7317 Now static, not extern.
7318 * data.c (Qinterval): Remove; unused.
7319 (syms_of_data): Do not define 'interval'.
7320 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
7321 * window.h (decode_valid_window):
7324 * character.c, charset.c, chartab.c: Use bool for booleans.
7325 * character.c (lisp_string_width, string_count_byte8)
7326 (string_escape_byte8):
7327 * charset.c (charset_map_loaded, load_charset_map, read_hex):
7328 (load_charset_map_from_file, map_charset_chars)
7329 (Fdefine_charset_internal, define_charset_internal)
7330 (Fdeclare_equiv_charset, find_charsets_in_text)
7331 (Ffind_charset_region, char_charset, Fiso_charset):
7332 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
7333 (sub_char_table_set, sub_char_table_set_range)
7334 (char_table_set_range, optimize_sub_char_table)
7335 (map_sub_char_table):
7336 Use bool for boolean.
7337 * character.c (str_to_unibyte): Omit last boolean argument; it was
7338 always 0. All callers changed.
7339 * character.h, charset.h: Adjust to match previous changes.
7340 * character.h (char_printable_p): Remove decl of nonexistent function.
7341 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
7342 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
7343 are all boolean, so make them single-bit bitfields.
7345 * lisp.h (ASET): Remove attempt to detect side effects.
7346 It was meant to be temporary and it often doesn't work,
7347 because when IDX has side effects the behavior of IDX==IDX
7348 is undefined. See Stefan Monnier in
7349 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
7351 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
7353 * lisp.h (functionp): New function (extracted from Ffunctionp).
7354 (FUNCTIONP): Use it.
7355 * eval.c (Ffunctionp): Use it.
7357 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7359 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7360 as that's faster and simpler than static storage. Don't bother
7361 with the g_main_context_query overhead if g_main_context_pending
7362 says no events are pending.
7363 (gfds, gfds_size): Remove these static vars.
7364 (xgselect_initialize): Remove; no longer needed.
7365 All uses and decls removed.
7367 * emacs.c (fatal_error_signal_hook): Remove.
7368 All uses removed. This leftover from old code was always 0.
7370 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
7371 * casefiddle.c (casify_object, casify_region):
7372 * casetab.c (set_case_table):
7373 * category.c, category.h (word_boundary_p):
7374 * category.h (CHAR_HAS_CATEGORY):
7375 Use bool for booleans, instead of int.
7377 2012-08-25 Eli Zaretskii <eliz@gnu.org>
7379 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
7381 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7383 On assertion failure, print backtrace if available.
7384 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
7385 (die) [ENABLE_CHECKING]: Print a backtrace if available.
7386 * Makefile.in (LIB_EXECINFO): New macro.
7389 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
7390 * bytecode.c (exec_byte_code):
7391 * callint.c (check_mark, Fcall_interactively):
7392 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
7393 (getenv_internal, sync_process_alive, call_process_exited):
7394 * lisp.h (USE_SAFE_ALLOCA):
7395 Use bool for booleans, instead of int.
7396 * lisp.h, process.h: Adjust prototypes to match above changes.
7397 * callint.c (Fcall_interactively): Don't assume the mark's
7398 offset fits in 'int'.
7400 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7402 * buffer.c, buffer.h: Use bool for boolean.
7403 * buffer.c (reset_buffer_local_variables)
7404 (buffer_lisp_local_variables, Fset_buffer_modified_p)
7405 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
7406 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
7407 (overlay_touches_p, overlay_strings, Foverlay_put)
7408 (report_overlay_modification, call_overlay_mod_hooks):
7409 (mmap_enlarge, mmap_set_vars):
7410 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7411 Use bool for booleans, instead of int.
7412 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7413 since the 1-or-0 return value is always ignored anyway.
7414 (mmap_initialized_p):
7415 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7416 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7418 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7420 * bidi.c: Use bool for boolean.
7421 This is a bit more readable, and makes the text segment of bidi.o
7422 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7423 Presumably it's faster too.
7424 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
7426 (bidi_cache_find_level_change, bidi_cache_iterator_state)
7427 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
7428 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
7429 (bidi_explicit_dir_char, bidi_level_of_next_char)
7430 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7431 Use bool for booleans, instead of int.
7432 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7433 (bidi_unshelve_cache): Adjust decls to match code.
7435 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7437 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7440 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7442 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7443 * atimer.h: Include <stdbool.h>.
7445 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7447 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7448 compile time tests instead of run time tests on systems that do
7450 (FRAME_MAC_P): Remove leftover from deleted code.
7451 * frame.c (syms_of_frame): Remove leftover from deleted code.
7453 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
7455 * nsterm.m (insertText:): Don't clear modifiers if code is space.
7457 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7459 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7460 Otherwise, the compiler complains about (A?B:C) where B is void
7461 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7462 (fontset_add): Return void, for FONTSET_ADD.
7464 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7466 * alloc.c: Use bool for booleans.
7467 (gc_in_progress, abort_on_gc)
7468 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7469 (dont_register_blocks) [GC_MALLOC_CHECK]:
7470 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
7471 (check_string_bytes, make_specified_string, memory_full)
7472 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
7473 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7474 (mark_stack, valid_pointer_p, make_pure_string)
7475 (Fgarbage_collect, survives_gc_p, gc_sweep):
7476 Use bool for booleans, instead of int.
7477 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7478 Remove unused local.
7479 * alloc.c (PURE_POINTER_P):
7480 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7481 * editfns.c (Fformat):
7482 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7484 * fns.c (sweep_weak_table):
7485 * lisp.h (suppress_checking, push_message, survives_gc_p)
7486 (make_pure_string, gc_in_progress, abort_on_gc):
7487 * lread.c (readchar, read1):
7488 * print.c (Fprin1_to_string):
7489 * xdisp.c (push_message):
7490 Use bool for booleans affected directly or indirectly by
7493 Make recently-introduced setters macros.
7494 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7495 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7496 (set_fontset_default, set_fontset_fallback): Rename from their
7497 upper-case counterparts, and make them functions rather than macros.
7498 This is more consistent with the other recently-introduced setters.
7499 These don't need to be inline, since they're local.
7501 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7503 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7504 the loop (Bug#12247).
7506 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7508 * lisp.h (vcopy): Use memcpy rather than our own loop.
7509 This fixes a performance regression introduced by the recent
7510 addition of vcopy. This means 'vcopy' will need to be modified
7511 for a copying collector, but that's OK. Also, tighten the
7512 checking in the assertion.
7514 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7516 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7517 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7518 non-base glyph for the width of the base character, according to
7519 what x_draw_composite_glyph_string_foreground expects.
7520 Generate WADJUST value according to composition_gstring_width's
7521 expectations, to produce correct width of the composed character.
7522 Reverse the sign of the DU offset produced by ScriptPlace.
7524 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7526 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7528 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7530 Avoid direct writes to contents member of struct Lisp_Vector.
7531 * lisp.h (vcopy): New function to copy data into vector.
7532 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7533 * fns.c (Ffillarray): Use ASET.
7534 * keyboard.c (timer_check_2): Use AREF and ASET.
7535 (append_tool_bar_item, Frecent_keys): Use vcopy.
7536 * lread.c (read_vector): Use ASET.
7537 * msdos.c (Frecent_doskeys): Use vcopy.
7538 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7539 (Finternal_merge_in_global_face): Use ASET and vcopy.
7540 * xfont.c (xfont_list_pattern): Likewise.
7542 2012-08-21 Martin Rudalics <rudalics@gmx.at>
7544 * window.c (Fwindow_point): For the selected window always return
7545 the position of its buffer's point.
7546 (Fset_window_point): For the selected window always go in its
7547 buffer to the specified position.
7549 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7551 Setter macros for fontsets.
7552 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7553 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7554 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7557 2012-08-20 Glenn Morris <rgm@gnu.org>
7559 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7560 Don't assume that `ln -f' works.
7562 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7564 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
7565 and later about non-assignments with no effect. See discussion at
7566 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
7569 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7571 Inline setter functions for Lisp_Objects slots of struct specbinding.
7572 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
7575 2012-08-20 Martin Rudalics <rudalics@gmx.at>
7577 * window.c (select_window): Always make selected window's buffer
7580 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7582 Use AREF and ASET for docstrings of category tables.
7583 * category.h (CATEGORY_DOCSTRING): Use AREF.
7584 (SET_CATEGORY_DOCSTRING): Use ASET.
7585 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
7587 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7589 Inline setter functions for hash table members.
7590 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
7591 (set_hash_hash, set_hash_index): Rename with _slot suffix.
7592 (set_hash_key_and_value, set_hash_index, set_hash_next)
7593 (set_hash_hash): New functions.
7594 * charset.c, fns.c: Adjust users.
7596 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7598 Inline getter and setter functions for per-buffer values.
7599 * buffer.h (per_buffer_default, set_per_buffer_default)
7600 (per_buffer_value, set_per_buffer_value): New functions.
7601 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
7602 * buffer.c, data.c: Adjust users.
7604 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
7606 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
7608 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7610 Rely on <config.h> + <unistd.h> to declare 'environ',
7611 as gnulib does this if the system doesn't.
7612 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7613 Remove declaration. MS-Windows declares it on stdlib.h which is
7614 included by conf_post.h.
7615 * emacs.c (environ) [DOUG_LEA_MALLOC]:
7616 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
7617 * vm-limit.c: Include <unistd.h>, for 'environ'.
7619 * unexaix.c, unexcoff.c: Include "mem-limits.h".
7620 (start_of_data): Remove decl; mem-limits.h provides it.
7622 * xdisp.c (handle_invisible_prop): Make it a bit faster
7623 and avoid a gcc -Wmaybe-uninitialized diagnostic.
7625 2012-08-19 Chong Yidong <cyd@gnu.org>
7627 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
7630 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
7632 * .gdbinit: Use call instead of set when calling a function in the
7635 * data.c (set_internal): Don't use set_blv_found.
7636 (Fkill_local_variable): Likewise.
7638 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
7640 * nsfont.m (ns_ascii_average_width): Ensure the string
7641 ascii_printable is initialized with a null-terminated character
7642 array. Otherwise, it can contain undesired extra characters.
7644 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7646 port new setting code to Sun C 5.8 2005/10/13
7647 * chartab.c, lisp.h (char_table_set, char_table_set_range):
7648 Return void, not Lisp_Object. Otherwise, the compiler
7649 complains about (A?B:C) where B is void and C is Lisp_Object
7650 when compiling CHAR_TABLE_SET, due to the recent change to
7651 the API of sub_char_table_set_contents.
7653 2012-08-18 Chong Yidong <cyd@gnu.org>
7655 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
7656 for the string case (Bug#3874).
7658 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7660 * buffer.h (BSET): Remove (Bug#12215).
7661 Replace all uses with calls to new setter functions.

7689 * category.c (bset_category_table):
7690 * syntax.c (bset_syntax_table):
7691 New setter functions.
7693 * process.h (PSET): Remove (Bug#12215).
7694 Replace all uses with calls to new setter functions.
7695 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
7696 (PROCESS_INLINE): New macro.
7697 (pset_childp): New setter function.
7698 (pset_gnutls_cred_type) [HAVE_GNUTLS]: New setter function.
7699 * process.c (PROCESS_INLINE):
7700 Define to EXTERN_INLINE, so that the corresponding functions
7701 are compiled into code.
7702 (pset_buffer, pset_command, pset_decode_coding_system)
7703 (pset_decoding_buf, pset_encode_coding_system)

7705 (pset_plist, pset_sentinel, pset_status, pset_tty_name)
7706 (pset_type, pset_write_queue): New setter functions.
7708 * window.h (WSET): Remove (Bug#12215).
7709 Replace all uses with calls to new setter functions.
7710 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
7711 (WINDOW_INLINE): New macro.

7715 (wset_window_end_pos, wset_window_end_valid)
7716 (wset_window_end_vpos): New setter functions.
7717 * window.c (WINDOW_INLINE):

8626 (INLINE_HEADER_END): New macros.
8627 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

8652 This how ASET and AREF are supposed to work, and makes
8653 it easier to think about future improvements. See
8654 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.

9067 * alloc.c (listn): Fix the order the arguments are consed onto the
9070 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
9071 enumeration constants, as PURE and HEAP are too general, and clash
9072 with other headers and sources, such as gmalloc.c and the
9073 MS-Windows system headers. All users changed.
9075 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9077 Revert last save_excursion_save and save_excursion_restore changes.
9078 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

9088 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
9090 Improve GDB symbol export (Bug#12036).
9091 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
9092 arms of an 'if', not using conditional expressions; otherwise GDB
9093 complains about the types in the unevaluated arm when the argument
9094 is an integer literal.
9095 (xgetint): Simplify expression.
9096 * alloc.c (gdb_make_enums_visible): New constant. This ports to
9097 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
9098 Zaretskii in <http://bugs.gnu.org/12036#13>.
9099 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
9100 needed now that we have gdb_make_enums_visible.
9101 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
9102 (enum enum_USE_LSB_TAG):
9103 New enum types, packaging up enums that need to be exported to GDB.
9105 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9107 Utility function to make a list from specified amount of objects.

9121 * xdisp.c (syms_of_xdisp): Likewise.
9122 * xfns.c (syms_of_xfns): Likewise.
9124 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9126 Fast save_excursion_save and save_excursion_restore.
9127 * lisp.h (struct Lisp_Excursion): New data type.
9128 (PVEC_EXCURSION): New pseudovector type.
9129 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
9130 to deal with it. Adjust comments.
9131 (init_marker, attach_marker): New prototype.
9132 (unchain_marker): Adjust prototype.

9141 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
9143 Fix export of symbols to GDB (Bug#12036).
9144 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
9145 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
9146 emacs.c, as this is a more-suitable home. Had this been done earlier
9147 the fix for 12036 would have avoided some of the problems noted in
9148 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
9149 would have been more obvious.
9150 * emacs.c: Do not include <verify.h>; no longer needed.
9151 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
9152 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
9153 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9154 Remove; now done in lisp.h.
9155 * lisp.h (PUBLISH_TO_GDB): New macro.
9156 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
9157 (DATA_SEG_BITS): Use it.
9158 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
9159 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
9160 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
9161 not be usable in #if. This simplifies things.
9163 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
9165 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
9167 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
9169 Simplify export of symbols to GDB (Bug#12036).
9170 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
9171 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
9172 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
9173 Adjust to changes in lisp.h and emacs.c, by using
9174 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
9175 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
9176 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
9177 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
9178 instead of gdb_valbits.
9179 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
9180 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
9181 instead of gdb_array_mark_flag.
9182 (xboolvector): Get size from $->size, not $->header.size.
9183 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
9184 (xreload, hook-run, hookpost-run): Remove.
9185 * emacs.c: Include <verify.h>.
9186 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
9187 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
9189 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
9190 (gdb_USE_LSB_TAG): New enum constants.
9191 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9192 Also define these as enum constants, so they're visible to GDB.
9193 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
9194 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
9195 as constants, so they're visible to GDB.
9196 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
9197 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
9198 Now enum constants, not macros, so they're visible to GDB.
9199 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
9200 more convenient now. All uses changed.
9201 (VALMASK) [USE_LSB_TAG]: Also define in this case.
9202 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
9204 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

9209 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
9211 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
9212 add argument, tune behavior, and adjust all callers.
9214 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
9216 Use typedef for EMACS_INT, EMACS_UINT.
9217 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
9218 than macros. This simplifies debugging in the usual case, since
9219 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
9220 and it allows expressions involving EMACS_INT casts.
9221 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
9223 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
9225 * nsterm.m (ns_read_socket): Return early if there is a modal
9228 2012-07-25 Martin Rudalics <rudalics@gmx.at>

9231 that FOCUS-FRAME can be omitted.
9233 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
9235 Adjust buffer text indirection counters at the end of Fkill_buffer.
9236 * buffer.c (Fkill_buffer): Adjust indirection counters when the
9237 buffer is definitely dead. This should really fix an issue reported
9238 by Christoph Scholtes again. (Bug#12007).
9239 (init_buffer_once): Initialize indirection counters of
9240 buffer_defaults and buffer_local_symbols (for sanity and safety).
9242 2012-07-24 Eli Zaretskii <eliz@gnu.org>
9244 * xdisp.c (init_iterator): Don't compute dimensions of truncation
9245 and continuation glyphs on tooltip frames, leave them at zero.
9246 Avoids continued lines in tooltips. (Bug#11832)
9248 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
9250 Simplify copy_overlay.
9251 * buffer.c (copy_overlay): Simplify. Use build_marker.

9260 it signals an error when a tooltip frame is being created.
9262 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9264 Cleanup miscellaneous objects allocation and initialization.

9271 (build_overlay): Add prototype.
9273 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9275 Swap buffer text indirection counters in Fbuffer_swap_text.
9276 * buffer.c (Fbuffer_swap_text): Swap indirections too.
9277 This avoids crash reported by Christoph Scholtes at
9278 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
9280 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
9282 * nsmenu.m (Popdown_data): New struct.
9283 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
9285 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
9286 (initWithContentRect): Make imgView and contentView non-static
9287 and autorelease them. Also autorelease img and matrix (Bug#12005).
9288 (dealloc): Remove (Bug#12005).
9290 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
9292 Adjust consing_since_gc when objects are explicitly freed.

9305 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
9307 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
9308 as it's limited by the amount of memory, not by INT_MAX.
9310 2012-07-21 Eli Zaretskii <eliz@gnu.org>
9312 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
9313 in special-event-map. See the discussion at
9314 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
9317 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning
9318 info.dwItemData. Fixes crashes on 64-bit Windows.

9372 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
9373 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
9374 Adjust users accordingly.
9375 * font.h (font_open_by_name): Adjust prototype.
9377 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>

9393 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
9394 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
9395 'for_each_per_buffer_object_at'.
9396 All uses changed. It's better to use upper-case for macros that
9397 cannot be implemented as functions, to give the reader a clue
9398 that they're special.
9400 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
9402 * alloc.c (Fgarbage_collect): Tweak docstring.

9443 * intervals.c (merge_interval_right, merge_interval_left):
9444 Do not zero out this interval if it is absorbed by its children,
9445 as this interval's total length doesn't change in that case. See
9446 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
9448 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
9450 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
9451 when invoking (make-bool-vector N t) and N is a positive
9452 multiple of 8 -- the last 8 bits were mistakenly cleared.
9454 Remove some struct layout assumptions in bool vectors.
9455 * alloc.c (bool_header_size): New constant.
9456 (header_size, word_size): Move earlier, as they're now used earlier.
9457 Use 'word_size' in a few more places, where it's appropriate.
9458 (Fmake_bool_vector, sweep_vectors): Don't assume that there is no
9459 padding before the data member of a bool vector.
9460 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
9461 than doing the check by hand with an abort ().
9463 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9465 * eval.c (Fdefvar): Don't check constants since we only set the var if
9466 it's not yet defined anyway (bug#11904).
9468 * lisp.h (last_undo_boundary): Declare new var.
9469 * keyboard.c (command_loop_1): Set it.
9470 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
9471 were auto-added by the command loop (bug#11774).
9473 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
9475 * w32font.c (Qsymbol): Remove local definition.

9962 * w32menu.c (Fx_popup_dialog): Likewise.
9964 2012-07-11 Glenn Morris <rgm@gnu.org>
9966 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
9967 since nothing has defined it on these platforms.

9981 2012-07-11 John Wiegley <johnw@newartisans.com>
9983 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
9984 function attribute, so we only use it if it exists in the
9987 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
9989 Avoid call to strlen in fast_c_string_match_ignore_case.
9990 * search.c (fast_c_string_match_ignore_case): Change to use
9991 length argument. Adjust users accordingly.
9992 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
9994 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

10011 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
10013 Avoid calls to strlen in font processing functions.
10014 * font.c (font_parse_name, font_parse_xlfd, font_parse_fcname)
10015 (font_open_by_name): Change to use length argument.

10028 Move DONT_REOPEN_PTY to configure.
10030 * sound.c (DEFAULT_SOUND_DEVICE) [!WINDOWSNT]:
10031 * s/netbsd.h (DEFAULT_SOUND_DEVICE): Let configure set it.
10033 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
10035 Remove "#define unix" that is no longer needed (Bug#11905).
10036 * s/aix4-2.h (unix): Remove; no longer needed.
10038 EMACS_TIME simplification (Bug#11875).
10039 This replaces macros (which typically do not work in GDB)
10040 with functions, typedefs and enums, making the code easier to debug.
10041 The functional style also makes code easier to read and maintain.
10042 * systime.h: Include <sys/time.h> on all hosts, not just if
10043 WINDOWSNT, since 'struct timeval' is needed in general.
10044 (EMACS_TIME): Now a typedef, not a macro.
10045 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
10047 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
10048 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)

10052 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
10053 which are not functions. All uses rewritten to use:
10054 (make_emacs_time): New function.
10055 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
10056 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
10057 not functions. All uses rewritten to use the following, respectively:
10058 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
10059 (add_emacs_time, sub_emacs_time): New functions.
10060 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
10061 * fileio.c (Fcopy_file):
10062 * xterm.c (XTflash): Get the current time closer to when it's used.
10063 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

10068 * doc.c (Fsnarf_documentation):
10069 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
10070 * frame.c (Fmake_terminal_frame):
10071 * gtkutil.c (get_utf8_string):
10073 * nsmenu.m (ns_update_menubar):
10074 * regex.c (regerror):
10075 Prefer memcpy to strncpy and strncat when either will do.
10076 * fileio.c (Fsubstitute_in_file_name):
10077 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
10078 (menu_separator_name_p):
10079 * nsmenu.m (ns_update_menubar):
10080 Prefer memcmp to strncmp when either will do.
10081 * nsterm.m: Include <ftoastr.h>.
10083 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
10084 Prefer snprintf to strncpy.
10085 * nsterm.m (ns_term_init):
10086 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
10087 * nsterm.m (ns_term_init):
10088 Avoid the need for strncpy, by using build_string or
10089 make_unibyte_string directly. Use dtoastr, not snprintf.
10090 * process.c (Fmake_network_process): Diagnose service names that
10091 are too long, rather than silently truncating them or creating
10092 non-null-terminated names.
10093 (Fnetwork_interface_info): Likewise, for interface names.
10094 * sysdep.c (system_process_attributes) [GNU_LINUX]:
10095 Prefer sprintf to strncat.
10096 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
10097 Prefer vsnprintf to vsprintf + strncpy.
10099 2012-07-10 Glenn Morris <rgm@gnu.org>
10101 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
10102 Clarify fallback case.
10104 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10106 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
10107 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
10108 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
10109 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
10110 where argument type is known to be a Lisp_Cons.
10112 2012-07-10 Tom Tromey <tromey@redhat.com>
10114 * bytecode.c (BYTE_CODE_THREADED): New macro.
10115 (BYTE_CODES): New macro. Replaces all old byte-code defines.
10116 (enum byte_code_op): New type.
10117 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
10118 (exec_byte_code): Use them. Use token threading when applicable.
10120 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10122 Optimize pure C strings initialization.
10123 * lisp.h (make_pure_string): Fix prototype.
10124 (build_pure_c_string): New function, defined as static inline. This
10125 provides a better opportunity to optimize away calls to strlen when
10126 the function is called with compile-time constant argument.
10127 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
10128 argument, adjust users accordingly. Use build_pure_c_string where
10130 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
10131 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
10132 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
10134 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10136 Avoid calls to strlen in miscellaneous functions.
10137 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
10138 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
10139 * lread.c (openp): Likewise.
10141 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10143 Avoid calls to strlen in path processing functions.
10144 * fileio.c (file_name_as_directory): Add comment. Change to add
10145 srclen argument and return the length of result. Adjust users
10147 (directory_file_name): Fix comment. Change to add srclen argument,
10148 swap 1st and 2nd arguments to obey the common convention.
10149 Adjust users accordingly.
10150 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
10152 2012-07-10 Glenn Morris <rgm@gnu.org>
10154 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
10155 Move PENDING_OUTPUT_COUNT definition to configure.
10157 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
10158 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
10159 * s/gnu.h (DATA_START): Move definitions to configure.
10161 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
10162 We include usg5-4-common.h, which defines them both.
10164 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
10165 O_RDONLY already includes it).
10167 Stop ns builds setting the EMACSLOADPATH environment variable.
10168 * nsterm.m (ns_load_path): Rename from ns_init_paths.
10169 Now it does not set EMACSLOADPATH, just returns the load-path string.
10170 * nsterm.h: Update accordingly.
10171 * lread.c [HAVE_NS]: Include nsterm.h.
10172 (init_lread) [HAVE_NS]: Use ns_load_path.
10173 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
10175 2012-07-09 Glenn Morris <rgm@gnu.org>
10177 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
10178 since the included bsd-common.h does so.
10180 Stop ns builds setting the EMACSPATH environment variable.
10181 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
10182 (ns_init_paths): Do not set EMACSPATH.
10183 * nsterm.h (ns_exec_path): Add it.
10184 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
10187 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
10189 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
10191 * process.c (wait_reading_process_output): 'waitchannels' was unset
10192 when read_kbd || !NILP (wait_for_cell); fix this.
10194 Add GCC-style 'const' attribute to functions that can use it.
10195 * character.h (char_resolve_modifier_mask):
10196 * keyboard.h (make_ctrl_char):
10197 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
10198 (init_character_once, next_almost_prime, init_fns, init_image)
10199 (flush_pending_output, init_sound):
10200 * mem-limits.h (start_of_data):
10201 * menu.h (finish_menu_items):
10202 Add ATTRIBUTE_CONST.

10204 Declare the dummy function with ATTRIBUTE_CONST.
10205 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
10206 Add decls with ATTRIBUTE_CONST.
10208 Minor improvements to make_formatted_string.
10209 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
10210 where int is good enough, as vsprintf returns an int.
10211 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
10213 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10215 Use make_formatted_string to avoid double length calculation.
10216 * lisp.h (make_formatted_string): New prototype.
10217 * alloc.c (make_formatted_string): New function.
10218 * buffer.c (Fgenerate_new_buffer_name): Use it.

10222 * frame.c (make_terminal_frame, set_term_frame_name)
10223 (x_report_frame_params): Likewise.
10224 * image.c (gs_load): Likewise.
10225 * minibuf.c (get_minibuffer): Likewise.
10226 * msdos.c (dos_set_window_size): Likewise.
10227 * process.c (make_process): Likewise.
10228 * xdisp.c (ensure_echo_area_buffers): Likewise.
10229 * xsettings.c (apply_xft_settings): Likewise.
10231 2012-07-09 Glenn Morris <rgm@gnu.org>
10233 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
10234 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
10235 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.

10237 * callproc.c [HAVE_NS]: Include nsterm.h.
10238 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
10240 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10242 Move marker debugging code under MARKER_DEBUG.
10243 * marker.c (MARKER_DEBUG): Move marker debugging code under
10244 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
10245 for bootstrap with --enable-checking (~3x slowdown reported
10246 by Juanma Barranquero <lekktu@gmail.com>).
10247 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
10249 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
10251 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
10252 See <http://bugs.gnu.org/11825#29>.
10254 2012-07-08 Eli Zaretskii <eliz@gnu.org>
10256 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
10257 has no font, use the frame's font. (Bug#11813)
10258 (display_line): Add commentary about displaying truncation glyphs
10260 (produce_special_glyphs): Move here from term.c.
10262 * term.c (produce_special_glyphs): Move to xdisp.c.
10264 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
10267 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
10269 * xdisp.c (display_line): Avoid warning about implicit declaration
10272 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
10274 * lisp.h: Remove empty conditional.
10276 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10278 * lread.c (load_path_check): Now static.
10280 Fix some minor --with-ns problems found by static checking.
10281 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
10282 (x_set_font) [!HAVE_X_WINDOWS]:
10283 * image.c (xpm_load_image) [HAVE_NS]:
10284 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
10285 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
10286 Remove unused local.
10287 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
10288 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
10289 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
10290 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
10291 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
10292 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
10293 Fix pointer signedness problem.
10294 * xfaces.c (FRAME_X_FONT_TABLE):
10295 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
10297 2012-07-07 Glenn Morris <rgm@gnu.org>
10299 * lread.c (load_path_check): New function, split from init_lread.
10300 (init_lread): Reorganize. Motivation:
10301 If EMACSLOADPATH is set, check/warn about that rather than the
10302 defaults, which we are not going to use. Hence we can remove
10303 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
10304 Don't warn if site-lisp directories are missing.
10305 If not installed, start from a blank load-path, since
10306 PATH_LOADSEARCH refers to the eventual installation directories.
10308 2012-07-07 Eli Zaretskii <eliz@gnu.org>
10310 Support truncation and continuation glyphs on GUI frames, when
10311 fringes are disabled. (Bug#11832)
10312 * xdisp.c (init_iterator): Get dimensions of truncation and
10313 continuation glyphs even if on GUI frames.
10314 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10315 or both, are absent.
10316 (start_display, move_it_in_display_line_to): Handle the case of a
10317 GUI frame without a fringe to display continuation or truncation
10319 (insert_left_trunc_glyphs): Support GUI frames: make sure
10320 truncation glyphs overwrite enough glyphs from the current line to
10321 have sufficient space in pixels.
10322 (display_line): Support truncation and continuation glyphs on GUI
10323 frames. If some spare pixels are left on the line after inserting
10324 the truncation glyphs, fill that space with a stretch glyph of a
10325 suitably computed width.
10327 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10328 produce_glyphs, to support GUI sessions.
10330 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10332 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10334 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10336 Do not require float-time's arg to fit in time_t (Bug#11825).
10337 This works better on hosts where time_t is unsigned, and where
10338 float-time is applied to the (negative) difference between two times.
10339 * editfns.c (decode_time_components): Last arg is now double *,
10340 not int *, and means to store all the result as a double, without
10341 worrying about whether the seconds part fits in time_t.
10342 All callers changed.
10343 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10344 All callers changed.
10345 (Ffloat_time): Do not fail merely because the specified time falls
10346 outside of time_t range.
10348 2012-07-07 Glenn Morris <rgm@gnu.org>
10350 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
10351 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
10352 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
10354 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
10356 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
10357 Update dependencies.
10359 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
10361 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10363 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
10364 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
10365 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.

10381 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10382 Eli Zaretskii <eliz@gnu.org>
10384 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.

10386 Obsolete settings removed.
10388 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10390 * process.c: Avoid unnecessary calls to gettime.
10391 (wait_reading_process_output): Don't get the time of day
10392 when gobbling data immediately and not waiting, as there's no need
10393 for it in that case. This removes a FIXME.
10395 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10397 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10398 is defined (Bug#11768).

10406 Call byte_char_debug_check with correct arguments.
10408 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10410 Compile marker debugging code only if ENABLE_CHECKING is defined.
10411 * marker.c (byte_char_debug_check, count_markers):
10412 Use only if ENABLE_CHECKING is defined.
10413 (byte_debug_flag): Remove.
10414 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10415 Always call byte_char_debug_check if ENABLE_CHECKING is defined.

10445 * window.c (save_window_save): Likewise.
10447 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10449 Do not use Fdelete_overlay in delete_all_overlays
10450 to avoid redundant calls to unchain_overlay.
10451 * buffer.c (drop_overlay): New function.
10452 (delete_all_overlays, Fdelete_overlay): Use it.
10453 * minibuf.c (get_minibuffer): Fix comment.
10455 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10457 Port to OpenBSD 5.1 amd64.
10458 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10459 This is needed for OpenBSD, and should be harmless on all BSD systems.
10460 Also, include <sys/sysctl.h>, as it should be available on all
10461 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10462 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10463 use p_pid member, not kp_proc.pid.
10465 2012-07-06 Glenn Morris <rgm@gnu.org>
10467 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10469 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10471 More xmalloc and related cleanup.

10482 Omit needless casts involving void * pointers and allocation.
10483 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10484 as the former is more robust if P's type is changed.
10485 Prefer xzalloc to xmalloc + memset 0.
10486 Simplify malloc-or-realloc to realloc.
10487 Don't worry about xmalloc returning a null pointer.
10488 Prefer xstrdup to xmalloc + strcpy.

10491 * keyboard.c (apply_modifiers_uncached): Prefer local array to
10492 alloca of a constant.

10496 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10497 hscroll is larger than the line width. Fixes long and futile
10498 looping inside extend_face_to_end_of_line (on a TTY) producing
10499 glyphs that are not needed and thrown away.
10501 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10503 * marker.c (set_marker_restricted_both): Simplify by using
10506 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10508 * editfns.c (region_limit): Simplify by using clip_to_bounds.

10517 followed by gtk_box_set_homogeneous (Bug#11768).
10518 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10519 (update_theme_scrollbar_width, xg_create_scroll_bar):
10520 Use gtk_scrollbar_new (Bug#11768).

10522 (is_box_type): New function (Bug#11768).
10523 (xg_tool_item_stale_p): Call is_box_type.
10524 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10525 with default display (Bug#11768).
10527 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10529 * xdisp.c (window_hscroll_limited): New function.
10530 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10531 coordinates when window's hscroll is set to insanely large
10532 values. (Bug#11857)
10534 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

10598 Problem reported by Troels Nielsen in
10599 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10601 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10603 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10604 This should be fixed in a better way; see Eli Zaretskii in
10605 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10606 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10608 * fileio.c (time_error_value): Rename from special_mtime.
10609 The old name's problems were noted by Eli Zaretskii in
10610 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10612 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10613 This variable's comment says Emacs needs at least one GDB-visible
10614 symbol of type enum pvec_type, to work around GDB problems.
10615 The symbol's value doesn't matter.
10617 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10618 that causes compilation to fail on pre-C99 compilers.
10620 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10622 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

10646 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10647 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10648 abusing vector->header.next.nbytes.
10649 (live_vector_p): Use PVEC_TYPE.
10650 (mark_object): Adapt code to extract pvectype. Use switch.
10652 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10654 * doprnt.c (doprnt): Don't assume string length fits in 'int'.

10659 Fix compilation with --enable-gcc-warnings and -O1
10660 optimization level.
10661 * doprnt.c (doprnt): Change type of tem to int, initialize
10662 to avoid compiler warning. Add eassert.
10663 * search.c (simple_search): Initialize match_byte to avoid
10664 compiler warning. Add eassert.
10666 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10668 Avoid weird behavior with large horizontal scrolls.
10669 Without this change, for example, large hscroll values would
10670 mess up Emacs's display on Fedora 15 x86, presumably due to
10671 overflows in int calculations in the display code.
10672 Also, if buffers had long lines, Emacs would freeze.
10673 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10674 (set_window_hscroll): New function, containing the old guts of
10675 Fset_window_hscroll. Return the clipped value.
10676 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10677 This avoids the need to check against PTRDIFF_MAX.
10679 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10681 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10683 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10685 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10687 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10688 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10689 since GCC 4.4.6 issues a bogus warning for them.
10691 Fix bugs in file timestamp newness comparisons.
10692 * fileio.c (Ffile_newer_than_file_p):
10693 * lread.c (Fload): Use full timestamp resolution of files,
10694 not just the 1-second resolution, so that files that are only
10695 slightly newer still count as newer.
10696 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10697 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10699 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10701 * fileio.c: Improve handling of file time marker. (Bug#11852)

10708 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10709 marker for non-existing file. (Bug#11852)
10711 2012-07-03 Glenn Morris <rgm@gnu.org>
10713 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10714 and did not make it into globals.h).
10716 2012-07-03 Tom Tromey <tromey@redhat.com>

10774 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10776 * alloc.c (allocate_vector_block): Remove redundant
10777 calls to mallopt if DOUG_LEA_MALLOC is defined.
10778 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10779 avoid calls to mallopt if zero_vector is returned.
10781 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10783 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10784 is enabled, avoid dereferencing NULL current_sblock if
10787 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10789 Cleanup basic buffer management.
10790 * buffer.h (struct buffer): Change layout to use generic vector

10805 and related comments.

10809 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10810 wrapper that is not needed because the wrapped code is a no-op (zero
10811 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10812 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10814 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10816 * alloc.c (mark_buffer): Simplify. Remove prototype.
10817 (mark_object): Add comment. Reorganize marking of vector-like
10818 objects. Use CHECK_LIVE for all vector-like objects except buffers
10819 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10820 Avoid redundant calls to mark_vectorlike for bool vectors.
10822 2012-06-30 Glenn Morris <rgm@gnu.org>
10824 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10826 * epaths.in (PATH_SITELOADSEARCH): New.
10827 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10828 This is rather than relying on --enable-locallisppath elements
10829 having "site-lisp" in their names. (Bug#10208#25, 11658)
10831 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10833 * w32proc.c (sys_select): Accept and ignore one more argument.
10835 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10837 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10838 (pselect) [!MS_DOS]: Redirect to sys_select.
10840 * sysdep.c: Don't include dos.h and dosfns.h.
10842 * process.c (sys_select):
10843 * msdos.c (sys_select): Accept one more argument and ignore it.
10845 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10846 adapt data types and code to that.
10849 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10850 which clashes with the gnulib function of the same name.
10852 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10854 * font.c (font_style_to_value, font_style_symbolic)
10855 (font_prop_validate_style): Add type checks for values in
10858 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10860 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10863 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10865 * xdisp.c (try_window_id): Undo last change.
10867 * w32.c (getwd): Adjust commentary about startup_dir.
10868 (init_environment): Always call sys_access, even in non-MSVC
10869 builds. Don't chdir to the directory of the Emacs executable.
10870 This undoes code from 1997 which was justified by the need to
10871 "avoid conflicts when removing and renaming directories". But its
10872 downside was that every relative file name was being interpreted
10873 relative to the directory of the Emacs executable, which can never
10874 be TRT. In particular, it broke sys_access when called with
10875 relative file names.
10876 (sys_access): Map GetLastError to errno.
10878 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10880 * window.h (struct window): Change type of 'fringes_outside_margins'
10881 to bitfield. Fix comment. Adjust users accordingly.
10882 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
10884 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10887 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
10889 * gnutls.c (emacs_gnutls_handshake):
10890 Add QUIT to make the loop interruptible.
10892 2012-06-29 Glenn Morris <rgm@gnu.org>
10894 * charset.c (init_charset): Make lack of etc/charsets fatal.
10896 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

10900 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10902 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
10903 undefined. Convert from xassert to eassert.

10905 * nsterm.m: Likewise.
10907 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

10911 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
10913 Avoid integer overflow on scroll-left and scroll-right.
10914 * window.c (HSCROLL_MAX): New macro.
10915 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
10916 overflow when requested scroll falls outside ptrdiff_t range.
10918 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10920 * window.h (struct window): Change type of 'hscroll',
10921 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
10922 'last_modified' and 'last_overlay_modified' to EMACS_INT.
10923 Adjust users accordingly.
10924 * xdisp.c (try_cursor_movement): Replace type check with eassert.
10925 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
10926 from EMACS_INT to ptrdiff_t.
10927 (make_window): Omit redundant initialization.
10929 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

10945 enabled with --enable-checking=[all,glyphs] configure option.
10946 Fix GLYPH_DEBUG usage assuming that it may be undefined,
10947 adjust comments accordingly.

10949 undefined, adjust comments accordingly.

10996 * alloc.c (allocate_string_data): Remove dead code.
10997 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
10998 avoid GCC warning about unused macro.
11000 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
11002 * alloc.c (allocate_string): Omit intervals initialization.
11003 * alloc.c (make_uninit_multibyte_string): Initialize intervals

11028 * alloc.c (mark_memory): Do not check with -faddress-sanitizer
11029 when building with Clang.
11031 2012-06-26 Stefan Monnier <monnier@iro.umontreal.ca>

11058 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
11060 * alloc.c: Remove build_string.
11061 * lisp.h: Define build_string as static inline. This provides
11062 a better opportunity to optimize away calls to strlen when the
11063 function is called with compile-time constant argument.
11064 * image.c (imagemagick_error): Convert to build_string.
11065 * w32proc.c (sys_spawnve): Likewise.

11068 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
11070 Use sprintf return value instead of invoking strlen on result.
11071 In the old days this wasn't portable, since some sprintf
11072 implementations returned char *. But they died out years ago and
11073 Emacs already assumes sprintf returns int.
11074 Similarly for float_to_string.
11075 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
11076 * ccl.c (ccl_driver):

11080 * print.c (print_object):
11081 * xdisp.c (message_dolog):
11082 * xfns.c (syms_of_xfns):
11083 Use sprintf or float_to_string result to avoid need to call strlen.
11084 * data.c (Fnumber_to_string):
11085 Use make_unibyte_string, since the string must be ASCII.
11086 * lisp.h, print.c (float_to_string): Now returns int length.
11087 * term.c (produce_glyphless_glyph):
11088 Use sprintf result rather than recomputing it.
11090 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
11091 * Makefile.in (ALL_CFLAGS):
11092 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
11093 * gmalloc.c, regex.c: Include <config.h> unconditionally.
11095 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
11097 * dispextern.h (xstrcasecmp): Define to library function
11098 strcasecmp if available.
11099 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.

11116 * gtkutil.c (get_utf8_string): Remove redundant assignment.
11117 sprintf already null-terminates its output.
11119 * xfns.c (x_window): Remove redundant cast.
11121 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
11123 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
11124 `const char *' to `char *' to avoid compiler warning.
11126 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11128 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
11129 instead of truncating it to 63 (admittedly a generous limit).
11131 * process.c: Fix spelling and caps in comments.
11133 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
11135 * emacs.c (setpgrp): Remove definition, unused.

11145 (SYSTIME_H): Add nt/inc/sys/time.h.
11147 * systime.h [WINDOWSNT]: Include sys/time.h.
11149 * s/ms-w32.h (struct timespec): Definition moved from
11150 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.

11182 Remove unnecessary forward decls.
11184 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11186 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
11187 * lisp.h (WAIT_READING_MAX): New macro.
11188 * dispnew.c (Fsleep_for, sit_for):
11189 * keyboard.c (kbd_buffer_get_event):
11190 * process.c (Faccept_process_output):
11191 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
11192 This improves on the previous patch, which introduced a bug
11193 when time_t is unsigned and as wide as intmax_t.
11194 See <http://bugs.gnu.org/9000#51>.
11196 2012-06-23 Eli Zaretskii <eliz@gnu.org>

11212 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
11213 Privately reported by Herbert J. Skuhra.
11214 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
11216 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
11217 not make_lisp_timeval, when the argument is of type EMACS_TIME.
11219 2012-06-23 Eli Zaretskii <eliz@gnu.org>
11221 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
11222 last argument of make_unibyte_string.
11224 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
11225 language ID in the event parameters.
11227 * w32term.c (w32_read_socket): Put the new keyboard codepage into
11228 event.code, not the obscure "character set ID".
11230 2012-06-23 Chong Yidong <cyd@gnu.org>
11232 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

11241 * s/ms-w32.h (pselect): Redirect to sys_select.
11243 * sysselect.h [WINDOWSNT]: Don't include sys/select.h.
11245 * ralloc.c (r_alloc_inhibit_buffer_relocation): Fix stupid thinko
11246 in the logic of incrementing and decrementing the value of
11247 use_relocatable_buffers.
11249 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
11251 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
11252 Privately reported by Herbert J. Skuhra.

11261 Support higher-resolution time stamps (Bug#9000).
11262 The time stamps are only nanosecond-resolution at the C level,
11263 since that's the best that any real-world system supports now.
11264 But they are picosecond-resolution at the Lisp level, as that's
11265 easy, and leaves room for future OS improvements.
11267 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
11270 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
11271 Don't get current time unless it's needed.
11273 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
11274 now provides it if it's absent.
11275 (start_atimer): Port to higher-res time stamps.
11276 Check for time stamp overflow. Don't get current time more
11277 often than is needed.
11279 * buffer.h (struct buffer): Buffer modtime now has high resolution.
11280 Include systime.h, not time.h.
11281 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
11283 * dired.c: Include stat-time.h.
11284 (Ffile-attributes): File times now have higher resolution.
11286 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
11287 (struct image): Timestamp now has higher resolution.
11289 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
11290 has at least microseconds now. All uses removed.
11291 (update_frame, update_single_window, update_window, update_frame_1)
11292 (Fsleep_for, sit_for): Port to higher-resolution time stamps.

11302 (make_time): Now static.
11303 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
11304 Report an error if the time is invalid, rather than having the caller
11307 * fileio.c: Include <stat-time.h>
11308 (Fcopy_file): Copy higher-resolution time stamps.
11309 Prefer to set the time stamp via a file descriptor if that works.

11327 Port to higher-resolution time stamps. Do not assume time_t is signed.
11328 (decode_timer): New function. Timers are now vectors of length 9,
11329 not 8, to accommodate the picosecond component.
11330 (timer_check_2): Use it.
11332 * nsterm.m (select_timeout, timeval_subtract): Remove.
11333 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
11334 as they're a bit more accurate and handle overflow better.
11335 (ns_select): Change prototype to be compatible with pselect.
11336 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11337 * nsterm.h (ns_select): Adjust prototype.

11354 (wait_reading_process_output):
11355 Port to ns-resolution time stamps.
11356 (Faccept_process_output, wait_reading_process_output):
11357 Check for time stamp overflow. Do not assume time_t is signed.
11358 (select_wrapper): Remove; we now use pselect.
11359 (Fprocess_attributes): Now generates ns-resolution time stamps.
11361 * sysdep.c: Include utimens.h. Don't include utime.h
11362 or worry about struct utimbuf; gnulib does that for us now.
11363 (gettimeofday): Remove; gnulib provides a substitute.
11364 (make_timeval): New function.
11365 (set_file_times): Now sets ns-resolution time stamps.
11366 New arg FD; all uses changed.

11369 Now returns ns-resolution time stamp. All uses changed.
11370 Check for time stamp overflow.

11373 provides a substitute now.
11375 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11376 since it guarantees struct timespec.
11377 (EMACS_TIME): Now struct timespec, so that we can support
11378 ns-resolution time stamps.
11379 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11380 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11381 (EMACS_USECS): Remove.
11382 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11383 so multiply the arg by 1000 before storing it.
11384 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
11386 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

11393 (make_timeval, make_lisp_time, decode_time_components): New decls.
11394 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11395 that it mishandled time_t overflow. You can't compare by subtracting!
11396 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11397 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
11399 * term.c: Include <sys/time.h>.

11404 in the undo buffer.
11405 (Fprimitive_undo): Use them when restoring time stamps.

11408 (w32_get_internal_run_time):
11409 Port to higher-resolution Emacs time stamps.

11413 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
11415 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
11416 for compatibility with pselect. Support ns-resolution time stamps.
11418 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
11420 * xselect.c (wait_for_property_change, x_get_foreign_selection):
11421 Check for time stamp overflow, and support ns-resolution time stamps.

11424 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
11425 (timeval_subtract): Remove; no longer needed.
11426 (XTflash, XTring_bell, x_wait_for_event):
11427 Port to ns-resolution time stamps. Don't assume time_t is signed.

11433 2012-06-22 Eli Zaretskii <eliz@gnu.org>
11435 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
11436 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11437 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11438 staticidx goes up to 1597 out of 1600 = 0x640.)
11440 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11442 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.

11454 access to `contents' member of Lisp_Vector objects with AREF and ASET
11457 2012-06-19 Chong Yidong <cyd@gnu.org>
11459 * frame.c (delete_frame): When selecting a frame on a different
11460 text terminal, do not alter the terminal's top-frame.

11464 (unwind_format_mode_line): Restore them.
11465 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
11467 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,

11476 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
11477 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
11478 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
11479 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
11480 (METER_1, METER_2): Simplify.
11482 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
11484 * data.c (Fdefalias): Return `symbol' (bug#11686).
11486 2012-06-18 Martin Rudalics <rudalics@gmx.at>
11488 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11489 gets killed during executing of this function (Bug#11665).
11490 Try to always return Qt when the buffer has been actually killed.
11491 (Vkill_buffer_query_functions): In doc-string say that functions
11492 run by this hook should not change the current buffer.
11494 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11496 Fix recently-introduced process.c problems found by static checking.

11516 * lisp.h (eassert): Assume C89 or later.
11517 This removes the need for CHECK.
11518 (CHECK): Remove. Its comments about always evaluating its
11519 argument were confusing, as 'eassert' typically does not evaluate
11522 * coding.c (produce_chars): Use ptrdiff_t, not int.
11524 * xterm.c (x_draw_underwave): Check for integer overflow.
11525 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

11712 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
11713 Use an inline function on all platforms when using the union type,
11714 since this is simpler and 'static inline' can be used portably

11856 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
11858 * doprnt.c (doprnt): Truncate multibyte char correctly.
11859 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
11860 would mishandle a string argument "Xc" if X was a multibyte
11861 character of length 2: it would truncate after X's first byte
11862 rather than including all of X.
11864 2012-06-06 Chong Yidong <cyd@gnu.org>
11866 * buffer.c (word_wrap): Doc fix.

11913 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11915 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11916 Convert pctcpu and pctmem to Lisp float properly.
11917 Let the compiler fold better, as 100.0/0x8000 is exact.
11919 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11921 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

11928 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
11930 For a 'struct window', replace some Lisp_Object fields to
11931 bitfields where appropriate, remove unused fields.
11932 * window.h (struct window): Remove unused 'last_mark_x' and
11933 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11934 change its type from Lisp_Object to bitfield.
11935 Change type of 'force_start', 'optional_new_start',
11936 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
11937 fields from Lisp_Object to bitfield. Adjust users accordingly.
11939 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11941 Pacify gcc -Wdouble-precision when using Xaw.
11942 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11943 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11944 Use 'float' consistently, rather than 'float' in most places
11945 and 'double' in a couple of places.
11947 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11949 * xdisp.c (handle_stop): Detect whether we have overlay strings
11950 loaded by testing it->current.overlay_string_index to be
11951 non-negative, instead of checking whether n_overlay_strings is
11952 positive. (Bug#11587)
11954 2012-05-31 Chong Yidong <cyd@gnu.org>
11956 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

11962 * search.c (search_buffer): Remove calls to
11963 r_alloc_inhibit_buffer_relocation, as it is now called by
11964 maybe_unify_char, which was the cause of relocation of buffer text
11967 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11969 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11970 for the duration of call to load_charset, to avoid problems with
11971 callers of maybe_unify_char that access buffer text through C
11974 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11975 decrement the inhibition flag, instead of just setting or
11978 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11980 Remove obsolete '#define static' cruft.
11981 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11982 This #undef was "temporary" in 2000; it is no longer needed
11983 now that '#define static' has gone away.
11984 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11985 (gray_bitmap_bits): Remove; no longer needed.
11986 All uses replaced with definiens.

11994 Define only on platforms that need it.
11995 * emacs.c: Include <sys/gmon.h> when profiling.
11996 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
11997 (__executable_start): Remove decl, since lisp.h does it now.
11998 (safe_bcopy): Remove decl; no longer has that name.
11999 (main): Coalesce #if into single bit of code, for simplicity.
12000 Cast pointers to uintptr_t, since standard libraries want integers
12002 * lisp.h (__executable_start): New decl.
12004 2012-05-31 Glenn Morris <rgm@gnu.org>

12029 Do not create empty overlays with the evaporate property (Bug#9642).
12030 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
12031 Bug#9642, but explicitly check that the buffer the overlay would
12032 be moved to is live and rearrange lines to make sure that errors
12033 will not put the overlay in an inconsistent state.
12034 (Fdelete_overlay): Cosmetics.
12036 2012-05-28 Eli Zaretskii <eliz@gnu.org>
12038 * w32term.c (my_bring_window_to_top): New function.
12039 (x_raise_frame): Use handle returned by DeferWindowPos, which
12040 could be different from the original one.

12056 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
12058 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

12072 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
12073 Only r_alloc_inhibit_buffer_relocation needed to be added;
12074 the others were already declared.
12076 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
12077 before checking whether it's out of range. Put the check inside
12079 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
12081 2012-05-27 Ken Brown <kbrown@cornell.edu>

12093 they are now on lisp.h.
12095 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
12097 * search.c (search_buffer): Use it to inhibit relocation of buffer
12098 text while re_search_2 is doing its job, because re_search_2 is
12099 passed C pointers to buffer text. (Bug#11519)
12101 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
12102 Update value to 24.
12104 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
12105 state after an additional call to move_it_in_display_line_to, keep
12106 the values of it->max_ascent and it->max_descent found for the
12108 (pos_visible_p): Revert the comparison against bottom_y to what it
12109 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
12112 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12114 Fix coding-related core dumps with gcc -ftrapv.
12115 The code was computing A - B, where A and B are pointers, and B is
12116 random garbage. This can lead to core dumps on platforms that
12117 have special pointer registers, and it also leads to core dumps on
12118 x86-64 when compiled with gcc -ftrapv. The fix is to compute
12119 A - B only when B is initialized properly.
12120 * coding.c (coding_set_source, coding_set_destination): Return void.
12121 (coding_change_source, coding_change_destinations): New functions,
12122 with the old behaviors of coding_set_source and coding_set_destination.

12133 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
12135 * w32console.c: Include window.h.
12136 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
12138 (initialize_w32_display): Initialize mouse-highlight data.
12140 * w32inevt.c: Include termchar.h and window.h.
12141 (do_mouse_event): Support mouse-autoselect-window. When the mouse
12142 moves, call note_mouse_highlight. If help_echo changed, call
12143 gen_help_event to produce help-echo message in the echo area.
12144 Call clear_mouse_face if mouse_face_hidden is set in the mouse
12147 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12149 * lread.c (read1): Simplify slightly to avoid an overflow warning
12150 with GCC 4.7.0 on x86-64.
12152 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12154 * bidi.c (bidi_mirror_char): Revert last change: an int is
12155 definitely wide enough here.

12165 (make_string_from_bytes, make_specified_string)
12166 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
12167 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
12169 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12170 (allocate_pseudovector):
12171 Use int, not EMACS_INT, where int is wide enough.
12172 (inhibit_garbage_collection, Fgarbage_collect):
12173 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12174 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
12175 int might not be wide enough.
12176 (bidi_cache_search, bidi_cache_find, bidi_init_it)

12193 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12194 (validate_region): Omit unnecessary test for b <= e,
12195 since that's guaranteed by the previous test.
12196 (adjust_overlays_for_delete): Avoid pos + length overflow.
12197 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
12198 (report_overlay_modification):
12199 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12200 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
12201 Omit pointer cast, which isn't needed anyway, and doesn't work
12202 after the EMACS_INT -> ptrdiff_t change.
12203 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
12204 * buffer.h: Adjust decls to match defn changes elsewhere.

12206 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12207 Use EMACS_INT, not int, where int might not be wide enough.
12208 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
12209 not int, to avoid needless 32-bit limit on 64-bit hosts.
12210 (exec_byte_code): Use tighter memory-full test, one that checks
12211 for alloca overflow. Don't compute the address of the object just
12212 before an array, as that's not portable. Use EMACS_INT, not
12213 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
12214 * callint.c (Fcall_interactively):
12215 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12216 * callproc.c (call_process_kill, Fcall_process):

12228 (casify_object): Avoid integer overflow when overallocating buffer.
12229 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
12230 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
12231 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
12232 * category.h (CATEGORYP): Don't assume arg is nonnegative.
12233 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

12237 For CCL_MapSingle, check that content and value are in int range.
12238 (ccl_driver, Fregister_code_conversion_map):
12239 Check that Vcode_version_map_vector is a vector.
12240 (resolve_symbol_ccl_program): Check that vector header is in range.
12241 Always copy the vector, so that we can check its contents reliably
12242 now rather than having to recheck each instruction as it's being
12243 executed. Check that vector words fit in 'int'.
12244 (ccl_get_compiled_code, Fregister_ccl_program)
12245 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
12246 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

12248 contents are in range.
12249 (Fccl_execute_on_string): Check that status is in range.
12250 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
12251 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
12252 Accept and return EMACS_INT, not int, because callers can pass values

12270 Remove now-unnecessary CHECK_NATNUMs.
12271 (Fdefine_charset_internal): Check ranges here, more carefully.
12272 Don't rely on undefined behavior with signed left shift overflow.
12273 Don't assume unsigned int fits into fixnum, or that fixnum fits
12274 into unsigned int. Don't require max_code to be a valid fixnum;
12275 that's not true for gb10830 4-byte on a 32-bit host. Allow
12276 invalid_code to be a cons, for the same reason. Require code_offset
12277 to be a character. Avoid int overflow if max_char is close
12279 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
12280 this is intended anyway and avoids some undefined behavior.
12281 (load_charset_map): Pass unsigned, not int, as 2nd arg of
12282 INDEX_TO_CODE_POINT, as that's what it expects.
12283 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
12284 * charset.h (DECODE_CHAR): Return int, not unsigned;
12285 this is what was intended anyway, and it avoids undefined behavior.
12286 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
12287 integer-overflow issues.
12288 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
12289 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
12290 where the argument is EMACS_INT, and this behavior is not intended.
12291 * chartab.c (Fmake_char_table, Fset_char_table_range)
12292 (uniprop_get_decoder, uniprop_get_encoder):
12293 Don't assume fixnum fits in int.
12294 * cmds.c (move_point): New function, that does the gist of
12295 Fforward_char and Fbackward_char, but does so while checking
12296 for integer overflow more accurately.
12297 (Fforward_char, Fbackward_char): Use it.
12298 (Fforward_line, Fend_of_line, internal_self_insert)
12299 (internal_self_insert):
12300 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

12947 * xterm.c (x_x_to_emacs_modifiers):
12948 Don't assume EMACS_INT overflows nicely into int.
12949 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
12950 may come from Lisp.

12959 2012-05-25 Glenn Morris <rgm@gnu.org>
12961 * lisp.mk (lisp): Update for more files being compiled now.
12963 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>

12966 (read_pure): Remove var.
12967 (unreadpure): Remove function.
12968 (readevalloop): Don't call read_list with -1 flag.
12969 (read1, read_vector): Don't test read_pure any more.

12981 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
12983 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
12986 This directory predates autoconf and is no longer needed nowadays.
12987 Move its few remaining bits of functionality to where they're needed.
12988 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

12993 * lisp.h (USE_LSB_TAG):
12994 * mem-limits.h (EXCEEDS_LISP_PTR):
12995 Use VAL_MAX, not VALBITS, in #if.
12996 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
12997 (EMACS_UINT): Define unconditionally now.
12998 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
12999 (BITS_PER_EMACS_INT): New constants, replacing
13000 what used to be in config.h, but not useful in #if.
13001 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
13002 define them any more.
13003 (VAL_MAX): New macro.
13005 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
13006 BITS_PER_EMACS_INT, in #if.
13007 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
13008 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
13009 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:

13011 Move here from removed file m/intel386.h.
13012 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
13013 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
13015 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
13017 Assume C89 or later.
13018 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.

13042 * xfns.c (x_in_use): Remove `static' qualifier.
13043 * xterm.h (x_in_use): Declare.
13044 * xgselect.c: Include xterm.h.
13045 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
13046 and `display_arg' (bug#9754).
13048 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>

13069 (Fword_search_forward, Fword_search_backward_lax)
13070 (Fword_search_forward_lax): Move functions to isearch.el
13071 (bug#10145, bug#11381).
13073 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
13075 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
13077 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
13079 * lread.c (init_obarray): Declare Qt and Qnil as special.
13081 2012-05-14 Glenn Morris <rgm@gnu.org>
13083 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
13084 Put "libexec" before "bin", for the sake of init_callproc_1.
13086 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13088 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
13090 * unexaix.c: Port to more-recent AIX compilers.
13091 (report_error, report_error_1, make_hdr, copy_sym)
13092 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
13093 Make arguments const char *, not char *, to avoid violations of C
13094 standard and to fix some AIX warnings reported by Gilles Pion.
13096 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13098 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
13099 already have overlays loaded.
13100 (handle_single_display_spec): Before returning without displaying
13101 fringe bitmap, synchronize the bidi iterator with the main display
13102 iterator, by calling iterate_out_of_display_property.
13103 (iterate_out_of_display_property): Detect buffer iteration by
13104 testing that it->string is a Lisp string.
13105 (get_next_display_element): When the current object is exhausted,
13106 and there's something on it->stack, call set_iterator_to_next to
13107 proceed with what's on the stack, instead of returning zero.
13108 (set_iterator_to_next): If called at the end of a Lisp string,
13109 proceed to consider_string_end without incrementing string
13110 position. Don't increment display vector index past the end of
13111 the display vector. (Bug#11417)
13112 (pos_visible_p): Don't report a position visible when move_it_to
13113 stopped at the last line of window, which happens to be scanned
13114 backwards by the bidi iteration. (Bug#11464)
13116 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13118 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
13119 and right-margin display specs even if the spec is invalid or we
13120 are on a TTY, and thus unable to display on the fringes.
13121 That's because the text with the property will not be displayed anyway,
13122 so we need to signal to the caller that this is a "replacing"
13123 display spec. This fixes display when the spec is invalid or we
13126 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13128 * unexaix.c (make_hdr): Fix typo in prototype.
13129 This bug broke the build on AIX. Problem reported by Gilles Pion.
13131 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
13133 * keyboard.c (kbd_buffer_get_event): Read special events also in
13134 batch mode. (Bug#11415)
13136 2012-05-12 Glenn Morris <rgm@gnu.org>

13140 2012-05-12 Eli Zaretskii <eliz@gnu.org>
13142 * lisp.mk (lisp): Add newcomment.elc.
13144 2012-05-12 Glenn Morris <rgm@gnu.org>
13146 * Makefile.in (MKDIR_P): New, set by configure.
13147 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
13149 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
13151 Remove unused function hourglass_started.
13152 * dispextern.h (hourglass_started):

13159 Update dependencies.
13161 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
13163 * xgselect.c (xg_select): Put maxfds+1 into a var.
13164 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
13166 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
13168 2012-05-10 Dave Abrahams <dave@boostpro.com>
13170 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
13171 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
13173 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
13175 * dbusbind.c (xd_registered_buses): New internal Lisp object.
13176 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
13177 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
13178 Initialize xd_registered_buses.
13180 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
13182 Untag more efficiently if USE_LSB_TAG.
13183 This is based on a proposal by YAMAMOTO Mitsuharu in
13184 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
13185 For an admittedly artificial (nth 8000 longlist) benchmark on
13186 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
13187 Emacs's overall text size by 1%.
13188 * lisp.h (XUNTAG): New macro.
13189 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
13190 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
13191 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
13192 * eval.c (Fautoload):
13193 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
13194 * frame.h (XFRAME): Use XUNTAG.
13196 Port recent dbusbind.c changes to 32-bit --with-wide-int.
13197 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
13198 Remove unportable assumptions about print widths of types like
13200 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
13201 intptr_t when converting between pointer and integer, to avoid GCC
13202 warnings about wrong width.
13204 2012-05-09 Eli Zaretskii <eliz@gnu.org>
13206 * w32proc.c (new_child): Force Windows to reserve only 64KB of
13207 stack for each reader_thread, instead of defaulting to 8MB
13208 determined by the linker. This avoids failures in creating
13209 subprocesses on Windows 7, see the discussion in this thread:
13210 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
13212 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
13214 Fix up display of the *Minibuf-0* buffer in the mini window.
13215 * keyboard.c (read_char): Don't clear the echo area if there's no
13217 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
13218 contents of *Minibuf-0*) if there's no message displayed in its stead.
13220 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
13222 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
13225 2012-05-06 Chong Yidong <cyd@gnu.org>
13227 * lisp.mk (lisp): Update.
13229 2012-05-05 Jim Meyering <meyering@redhat.com>
13231 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
13233 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
13235 * data.c (PUT_ERROR): New macro.
13236 (syms_of_data): Use it. Add new error type `user-error'.
13237 * undo.c (user_error): New function.
13238 (Fprimitive_undo): Use it.
13239 * print.c (print_error_message): Adjust print style for `user-error'.
13240 * keyboard.c (user_error): New function.
13241 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
13243 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
13245 Do not limit current-time-string to years 1000..9999.
13246 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
13247 (Fcurrent_time_string): Support any year that is supported by the
13248 underlying localtime representation. Don't use asctime, as it
13249 has undefined behavior for years outside the range -999..9999.
13251 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
13253 Fix race conditions involving setenv, gmtime, localtime, asctime.
13254 Without this fix, interrupts could mess up code that uses these
13255 nonreentrant functions, since setting TZ invalidates existing
13256 tm_zone or tzname values, and since most of these functions return
13257 pointers to static storage.
13258 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
13259 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
13260 Grow the critical sections to include not just invoking
13261 localtime/gmtime, but also accessing these functions' results
13262 including their tm_zone values if any, and any related TZ setting.
13263 (format_time_string): Last arg is now struct tm *, not struct tm **,
13264 so that the struct tm is saved in the critical section.
13265 All callers changed. Simplify allocation of initial buffer, partly
13266 motivated by the fact that memory allocation needs to be outside
13267 the critical section.
13269 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
13271 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
13272 with RESET_INTERVAL.
13274 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
13275 Remove duplicated buffer name initialization.
13277 2012-05-02 Jim Meyering <jim@meyering.net>
13279 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
13281 * xfns.c (x_window): Use xstrdup (Bug#11375).
13283 2012-05-02 Eli Zaretskii <eliz@gnu.org>
13285 * xdisp.c (pos_visible_p): If already at a newline from the
13286 display string before the 'while' loop, don't walk back the glyphs
13287 from it3.glyph_row. Solves assertion violation when the display
13288 string begins with a newline (egg.el). (Bug#11367)
13290 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
13292 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
13295 2012-05-01 Glenn Morris <rgm@gnu.org>
13297 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
13298 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
13299 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
13300 All were removed before 23.1.
13302 * dispnew.c: Remove HAVE_LIBNCURSES test;
13303 it is always true on relevant platforms.
13305 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
13306 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
13308 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
13310 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
13312 * .gdbinit (xpr): Remove checks for no longer existing misc types.
13313 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
13316 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
13318 Do not avoid creating empty evaporating overlays (Bug#9642).
13319 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13320 That is, do not delete an evaporating overlay if it becomes
13321 empty after its bounds are adjusted to fit within its buffer.
13322 This fix caused other problems, and I'm reverting it until we get
13323 to the bottom of them.
13325 2012-04-27 Chong Yidong <cyd@gnu.org>
13327 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
13329 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13331 * xdisp.c (pos_visible_p): If the window start position is beyond
13332 ZV, start the display from buffer beginning. Prevents assertion
13333 violation in init_iterator when the minibuffer window is scrolled
13334 via the scroll bar.
13336 * window.c (window_scroll_pixel_based): Likewise.
13338 2012-04-27 Chong Yidong <cyd@gnu.org>
13340 * keymap.c (where_is_internal): Doc fix (Bug#10872).
13342 2012-04-27 Glenn Morris <rgm@gnu.org>
13344 * fileio.c (Fcopy_file, Fset_file_selinux_context):
13345 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13347 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13349 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13350 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13352 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13354 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
13355 display element, check also the underlying string or buffer
13356 character. (Bug#11341)
13358 * w32menu.c: Include w32heap.h.
13359 (add_menu_item): If the call to AppendMenuW (via
13360 unicode_append_menu) fails, disable Unicode menus only if we are
13361 running on Windows 9X/Me.
13363 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13365 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13366 (xgetint): Add missing shift for LSB tags.
13368 2012-04-24 Martin Rudalics <rudalics@gmx.at>
13370 * keyboard.c (read_char): Don't wipe echo area for select window
13371 events: These might get delayed via `mouse-autoselect-window'
13374 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
13376 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
13377 manipulation of :loaded-from data.
13379 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
13381 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
13382 now a cons (bug#11311).
13384 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
13386 Do not create empty overlays with the evaporate property (Bug#9642).
13387 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13388 if it becomes empty after its bounds are adjusted to fit within
13389 its buffer. Without this fix, in a nonempty buffer (let ((o
13390 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13391 yields an empty overlay that has the evaporate property, which is
13392 not supposed to happen.
13394 Fix minor GTK3 problems found by static checking.
13395 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
13396 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13397 (struct _EmacsFixedClass, emacs_fixed_get_type):
13398 Move decls here from emacsgtkfixed.h, since they needn't be public.

13414 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
13415 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13416 (__malloc_size_t, __malloc_ptrdiff_t):
13417 Remove. All uses removed, replaced by the definiens if needed,
13418 since we can assume C89 or better now.
13419 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

13427 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
13428 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):

13436 Omit no-longer-needed casts.
13437 (valloc): Use getpagesize, not __getpagesize.
13438 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.

13494 * alloc.c: Handle unusual debugging option combinations.
13495 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
13496 since the two debugging options are incompatible.
13497 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS

13507 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13509 * sysdep.c [__FreeBSD__]: Minor cleanups.
13510 (list_system_processes, system_process_attributes) [__FreeBSD__]:
13511 Use Emacs indenting style more consistently. Avoid some casts.
13512 Use 'double' consistently rather than mixing 'float' and 'double'.
13514 2012-04-21 Eduard Wiebe <usenet@pusto.de>
13516 * sysdep.c (list_system_processes, system_process_attributes):
13517 Add implementation for FreeBSD (Bug#5243).

13523 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
13525 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
13526 It is never used otherwise.
13528 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
13530 * print.c (print_preprocess): Only check print_depth if print-circle
13532 (print_object): Check for cycles even when print-circle is nil and
13533 print-gensym is t, but only check print_depth if print-circle is nil.
13535 2012-04-20 Chong Yidong <cyd@gnu.org>
13537 * process.c (wait_reading_process_output): If EIO occurs on a pty,
13538 set the status to "failed" and ensure that sentinel is run.
13540 2012-04-20 Glenn Morris <rgm@gnu.org>
13542 * process.c (Fset_process_inherit_coding_system_flag)
13543 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

13551 row, return zero immediately.
13552 (try_cursor_movement): If inside continuation line, don't back up
13553 farther than the first row after the header line, if any.
13554 Don't consider the header-line row as "partially visible", even if
13555 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
13557 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

13571 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
13572 -Wunused-result, -Wunused-variable. This should go away once
13573 the Emacs and Gnulib regex code is merged.

13595 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
13596 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13597 (NEED_MEM_INSERT): New macro.
13598 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13599 Remove one incorrect comment and fix another.

13603 * ralloc.c (ALIGNED, ROUND_TO_PAGE, HEAP_PTR_SIZE)
13604 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
13605 (r_alloc_sbrk): Now static.
13607 Improve ralloc.c interface checking.
13608 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
13609 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
13610 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
13611 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)

13613 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
13614 Remove decls. This fixes an "It stinks!".
13616 * alloc.c (which_symbols): Fix alignment issue / type clash.
13618 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
13620 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
13621 (struct Lisp_Misc_Any): Likewise.
13622 (struct Lisp_Free): Likewise.

13631 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
13633 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
13634 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
13635 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
13636 * s/netbsd.h, s/sol2-6.h:
13637 Remove definition of GC_MARK_STACK, since the default now works.
13638 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
13639 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
13640 no longer the default.
13641 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
13643 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
13645 * lread.c (lisp_file_lexically_bound_p):
13646 Fix hang at ";-*-\n" (bug#11238).
13648 2012-04-14 Eli Zaretskii <eliz@gnu.org>
13650 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row

13655 * nsterm.m (constrainFrameRect): Always constrain when there is only
13656 one screen (Bug#10962).
13658 2012-04-13 Ken Brown <kbrown@cornell.edu>

13666 2012-04-11 Daniel Colascione <dancol@dancol.org>
13668 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13669 against is gone. It's better to use vfork now so that when Cygwin
13670 gains a new, working vfork, we use it automatically (bug#10398).

13690 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
13692 * w32.c (w32_delayed_load): Record the full path of the library
13693 being loaded (bug#10424).
13695 2012-04-09 Glenn Morris <rgm@gnu.org>
13697 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
13698 not just in the obarray, before snarfing them. (Bug#11036)
13700 * Makefile.in ($(leimdir)/leim-list.el):
13701 Pass EMACS rather than BUILT_EMACS.
13703 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
13705 * process.c (make_process):
13706 * process.h: Add integer `gnutls_handshakes_tried' member to
13709 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
13710 Add convenience `GNUTLS_LOG2i' macro.
13712 * gnutls.c (gnutls_log_function2i): Convenience log function.
13713 (emacs_gnutls_read): Use new log functions,
13714 `gnutls_handshakes_tried' process member, and
13715 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
13716 attempts per process (connection).
13718 2012-04-09 Chong Yidong <cyd@gnu.org>
13720 * eval.c (Fuser_variable_p, user_variable_p_eh)

13725 * minibuf.c (Fread_variable): Callers changed.
13727 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13729 * xdisp.c (set_cursor_from_row): If the display string appears in
13730 the buffer at position that is closer to point than the position
13731 after the display string, display the cursor on the first glyph of
13732 the display string. Fixes cursor display when a 'display' text
13733 property immediately follows invisible text. (Bug#11094)
13735 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13737 composite.c: use 'double' consistently
13738 * composite.c (get_composition_id): Use 'double' consistently
13739 instead of converting 'float' to 'double' and vice versa; this is
13740 easier to understand and avoids a GCC warning.
13742 2012-04-09 Glenn Morris <rgm@gnu.org>
13744 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13745 preparation for dumping it with emacs. (Bug#4789)
13746 (leimdir): New variable.
13747 ($(leimdir)/leim-list.el): New rule.
13748 (emacs$(EXEEXT)): Depend on leim-list.el.
13750 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)

13766 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
13767 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
13768 (mark_memory): Mark Lisp_Objects only if pointers might hide in
13769 objects, as mark_maybe_pointer will catch them otherwise.
13770 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
13771 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

13775 Fix typo that broke non-Windows builds.
13776 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
13778 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13780 Support building on MS-Windows with libxml2.
13782 * makefile.w32-in (OBJ2): Add xml.$(O).
13783 (GLOBAL_SOURCES): Add xml.c.
13784 ($(BLD)/xml.$(O)): New dependency list.
13786 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
13787 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
13788 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
13789 [!WINDOWSNT]: New macros.
13790 (init_libxml2_functions, libxml2_loaded_p): New functions.
13791 (parse_region): Call fn_xmlCheckVersion instead of using the macro
13792 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
13793 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
13794 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13796 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13797 Call init_libxml2_functions before calling libxml2 functions.
13798 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13800 * emacs.c: Don't include libxml/parser.h.
13801 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
13802 xmlCleanupParser directly.
13804 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
13806 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13808 * indent.c (Fvertical_motion): If there is a display string at
13809 point, use it.vpos to compute how many lines to backtrack after
13810 move_it_to point. (Bug#11133)
13812 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13814 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13815 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13816 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13817 macros related to unification of CJK characters. For the details,
13818 see the discussion following the message here:
13819 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
13821 2012-04-04 Chong Yidong <cyd@gnu.org>
13823 * keyboard.c (Vdelayed_warnings_list): Doc fix.
13825 2012-04-01 Eli Zaretskii <eliz@gnu.org>
13827 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
13828 instead of alloca. (Bug#11138)
13830 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>

13835 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13837 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13838 position we get to after a call to move_it_to fails the
13839 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13840 only if we wind up in a string from display property. (Bug#11063)
13842 * window.c (Fdelete_other_windows_internal): Invalidate the row
13843 and column information about mouse highlight, so that redisplay
13844 restores it after reallocating the glyph matrices. (Bug#7464)
13846 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13847 string comes from a `display' text property, use the buffer
13848 position of that property as if we actually saw that position in
13850 (move_it_by_lines): Remove the assertion that
13851 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13852 violated when there's a before-string at the beginning of a line.
13855 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13857 * xdisp.c (append_space_for_newline): If the default face was
13858 remapped, use the remapped face for the appended newline.
13859 (extend_face_to_end_of_line): Use the remapped default face for
13860 extending the face to the end of the line.
13861 (display_line): Call extend_face_to_end_of_line when the default
13862 face was remapped. (Bug#11068)
13864 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13866 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
13868 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13870 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
13872 2012-03-27 Glenn Morris <rgm@gnu.org>
13874 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
13877 2012-03-26 Kenichi Handa <handa@m17n.org>
13879 * dispextern.h (struct glyph): Fix previous change. Change the
13880 bit length of glyphless.ch to 25 (Bug#11082).
13882 2012-03-26 Chong Yidong <cyd@gnu.org>
13884 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13885 (command_loop_1): Use it; inhibit selection update for
13886 handle-select-window too (Bug#8996).
13888 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
13890 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13892 2012-03-25 Kenichi Handa <handa@m17n.org>
13894 * dispextern.h (struct glyph): Change the bit length of
13895 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13897 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13899 * s/ms-w32.h (tzname): Include time.h before redirecting to
13900 _tzname. Fixes the MSVC build. (Bug#9960)
13902 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
13904 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13907 * xterm.c (XTread_socket): Only modify handling_signal if
13908 !SYNC_INPUT. (Bug#11080)
13910 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13912 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13913 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13914 when fetching a multibyte character consumes more bytes than
13915 CHAR_BYTES returns, due to unification of CJK characters in
13916 string_char. (Bug#11073)
13918 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13920 * process.c (wait_reading_process_output): Handle pty disconnect
13921 by refraining from sending oneself a SIGCHLD (bug#10933).

13928 Mark string as coming from a prefix property.
13929 (handle_face_prop): Use default face for prefix strings (Bug#4281).
13930 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
13932 2012-03-21 Chong Yidong <cyd@gnu.org>
13934 * xfaces.c (Vface_remapping_alist): Doc fix.
13936 2012-03-20 Eli Zaretskii <eliz@gnu.org>
13938 * w32proc.c (Fw32_set_console_codepage)
13939 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
13942 2012-03-20 Chong Yidong <cyd@gnu.org>
13944 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
13945 to reflect default non-nil value of redisplay-dont-pause.
13947 2012-03-19 Kenichi Handa <handa@m17n.org>
13949 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
13950 it fit in a valid range (Bug#11003).
13952 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13954 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13955 that is not from display property, accept the row as a "cursor
13956 row" if one of the string's character has a non-nil `cursor'
13957 property. Fixes cursor positioning when there are newlines in
13958 overlay strings, e.g. in icomplete.el. (Bug#11035)
13960 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13962 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13964 2012-03-12 Chong Yidong <cyd@gnu.org>
13966 * eval.c (inhibit_lisp_code): Rename from
13967 inhibit_window_configuration_change_hook; move from window.c.
13969 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13970 * window.c (run_window_configuration_change_hook)
13971 (syms_of_window): Callers changed.
13973 2012-03-11 Chong Yidong <cyd@gnu.org>
13975 * keymap.c (Fkey_description): Doc fix (Bug#9700).
13977 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
13979 2012-03-10 Chong Yidong <cyd@gnu.org>
13981 * frame.c (other_visible_frames): Don't assume the selected frame
13982 is visible (Bug#10955).
13984 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
13986 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
13988 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
13990 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
13991 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13994 2012-03-03 Glenn Morris <rgm@gnu.org>
13996 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13998 2012-03-02 Eli Zaretskii <eliz@gnu.org>
14000 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
14001 position past the first glyph_row that ends at ZV. (Bug#10902)
14002 (redisplay_window, next_element_from_string): Fix typos in
14004 (redisplay_window): Pass to move_it_vertically the margin in
14005 pixels, not in screen lines.
14007 2012-03-02 Glenn Morris <rgm@gnu.org>
14009 * buffer.c (buffer-list-update-hook): Doc fix.
14011 2012-02-29 Eli Zaretskii <eliz@gnu.org>
14013 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
14014 push_it before setting up the iterator for the first overlay
14015 string, even if we have an empty string loaded.
14016 (next_overlay_string): If there's an empty string on the iterator
14017 stack, pop the stack. (Bug#10903)
14019 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
14021 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
14022 Suggested by Stefan Monnier in
14023 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
14024 * alloc.c (widen_to_Lisp_Object): New static function.
14025 (mark_memory): Also mark Lisp_Objects by fetching pointer words
14026 and widening them to Lisp_Objects. This would work even if
14027 USE_LSB_TAG is defined and wide integers are used, which might
14028 happen in a future version of Emacs.
14030 2012-02-25 Chong Yidong <cyd@gnu.org>
14032 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
14035 * xselect.c (Fx_selection_exists_p): Doc fix.
14036 (x_clipboard_manager_save_all): Print an informative message
14037 before saving to clipboard manager.
14039 2012-02-24 Chong Yidong <cyd@gnu.org>
14041 * keyboard.c (process_special_events): Handle all X selection
14042 requests in kbd_buffer, not just the next one (Bug#8869).
14044 2012-02-23 Chong Yidong <cyd@gnu.org>
14046 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
14047 call when setting menu-bar-lines and tool-bar-lines parameters.
14048 (unwind_create_frame_1): New helper function.
14050 * window.c (inhibit_window_configuration_change_hook): New var.

14069 when computing $valmask.
14071 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
14072 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
14073 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
14074 It's useless in that case, and it can cause problems on hosts
14075 that allocate halves of EMACS_INT values separately.
14076 Reported by Dan Horák. Diagnosed by Andreas Schwab in
14077 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
14078 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
14079 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
14080 it avoids undefined behavior on hosts where shifting right by more
14081 than the word width has undefined behavior.
14083 2012-02-19 Chong Yidong <cyd@gnu.org>
14085 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
14086 (Funhandled_file_name_directory, Ffile_name_as_directory)
14087 (Fdirectory_file_name, Fexpand_file_name)
14088 (Fsubstitute_in_file_name): Protect against invalid file handler
14089 return values (Bug#10845).
14091 2012-02-18 Eli Zaretskii <eliz@gnu.org>
14093 * .gdbinit (pitx): Fix incorrect references to fields of the
14096 2012-02-17 Chong Yidong <cyd@gnu.org>

14100 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
14102 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
14103 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
14105 2012-02-15 Chong Yidong <cyd@gnu.org>
14107 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
14108 marked as special. Also, starting docstrings with * is obsolete.
14110 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
14112 * gnutls.c (emacs_gnutls_write): Fix last change.

14121 * keymap.c (Fsingle_key_description): Handle char ranges.
14123 2012-02-12 Chong Yidong <cyd@gnu.org>
14125 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
14126 as that creates a dangerous corner case.
14128 * window.c (Fdelete_window_internal): Invalidate the mouse
14129 highlight (Bug#9904).
14131 2012-02-12 Glenn Morris <rgm@gnu.org>
14133 * xselect.c (Fx_own_selection_internal)
14134 (Fx_get_selection_internal, Fx_disown_selection_internal)
14135 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
14136 * nsselect.m (Fx_own_selection_internal)
14137 (Fx_disown_selection_internal, Fx_selection_exists_p)
14138 (Fx_selection_owner_p, Fx_get_selection_internal):
14139 Sync docs and argument specs with the xselect.c versions.
14141 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
14143 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
14145 2012-02-11 Eli Zaretskii <eliz@gnu.org>
14147 * w32select.c (Fx_selection_exists_p): Sync doc string and
14148 argument list with xselect.c. (Bug#10783)

14698 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
14699 verifies glyph row's hash code--we have just reallocated the
14700 glyphs, so their contents can be complete garbage. (Bug#10164)

14864 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
14865 is set, removing the need for VIRT_ADDRESS_VARIES.
14866 (PURE_P): Use a more-efficient implementation that needs just one
14867 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
14868 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
14869 to 4 (xorl, subq, cmpq, setbe).
14870 * alloc.c (pure): Always extern now, since that's the

14873 consistency with the new puresize.h.
14874 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
14875 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

14881 (erase_phys_cursor, update_window_cursor, show_mouse_face)
14882 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
14883 behave as if the cursor position were at the window margin.
14885 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14886 and the cursor position is out of bounds, behave as if the cursor
14887 position were at the window margin. (Bug#10075)
14889 2011-11-18 Chong Yidong <cyd@gnu.org>
14891 * window.c (Fwindow_combination_limit): Make first argument

14910 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
14912 * xdisp.c (row_hash): New function, body extracted from
14913 compute_line_metrics.
14914 (compute_line_metrics): Call row_hash, instead of computing the
14917 * dispnew.c (verify_row_hash): Call row_hash for computing the
14918 hash code of a row, instead of duplicating code from xdisp.c.
14920 * dispextern.h (row_hash): Add prototype.
14922 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
14924 * frame.c (delete_frame): Don't delete the terminal when the last

14960 * xdisp.c (display_line): Move the call to
14961 highlight_trailing_whitespace before the call to
14962 compute_line_metrics, since the latter needs to see the final
14963 faces of all the glyphs to compute ROW's hash value.

14973 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14974 with user-defined heap size. Bump the default size of the temacs

14978 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
14979 current_matrix and desired_matrix. (Bug#9990)
14980 (verify_row_hash) [XASSERTS]: New function.

15027 Avoid some portability problems by eschewing 'extern inline' functions.
15028 The trivial performance wins aren't worth the portability hassles; see
15029 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
15031 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

15097 * xmenu.c (cleanup_widget_value_tree): New function.
15098 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
15099 calling free_menubar_widget_value_tree directly (Bug#9830).
15101 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
15103 Fix some portability problems with 'inline'.
15104 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
15105 (window_box_width, window_box_left, window_box_left_offset)
15106 (window_box_right, window_box_right_offset): Declare extern.
15107 Otherwise, these inline functions do not conform to C99 and
15108 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
15109 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
15110 * intervals.c (adjust_intervals_for_insertion)
15111 (adjust_intervals_for_deletion): Now extern, because otherwise the
15112 extern inline functions 'offset_intervals' couldn't refer to it.
15113 (static_offset_intervals): Remove.
15114 (offset_intervals): Rewrite using the old contents of
15115 static_offset_intervals. The old version didn't conform to C99
15116 because an extern inline function contained a reference to an
15117 identifier with static linkage.
15119 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
15121 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

15139 (Fwindow_vscroll): Doc fix.
15140 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
15141 argument, since it makes no sense to pass a live window and for
15142 consistency with window-child.

15183 official. Move initialization of image_cache_refcount and
15184 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

15352 (w32font_open_internal, compute_metrics):
15353 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
15354 instead of calling the "wide" APIs directly.

15367 2011-10-27 Chong Yidong <cyd@gnu.org>
15369 * process.c (make_process): Set gnutls_state to NULL.
15371 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
15372 non-NULL, regardless of GNUTLS_INITSTAGE.

15421 (bidi_resolve_weak): Don't enter the expensive loop if the current
15422 position is before next_en_pos. Record the bidi type of the first
15423 non-ET, non-BN character we find, in addition to its position.
15424 (bidi_level_of_next_char): Invalidate next_en_type when
15425 next_en_pos is over-stepped.
15427 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
15429 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15430 * editfns.c: Rewrite current-time-zone so that it invokes
15431 the equivalent of (format-time-string "%Z") to get the time zone name.
15432 This fixes a bug when the time zone name contains characters that
15433 need converting from the system time locale to Emacs internal format.
15434 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15435 that patch fixed format-time-string to do the conversion, but
15436 I forgot to fix current-time-zone.
15437 (format_time_string): New function, containing most of
15438 what Fformat_time_string used to contain.
15439 (Fformat_time_string): Rewrite in terms of format_time_string.
15440 This doesn't change this function's behavior.
15441 (current-time-zone): Rewrite to use format_time_string.
15442 This fixes the bug reported by Michael Schierl in
15443 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15444 Jason Rumney's 2007-06-07 change worked around this bug, but
15446 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15448 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15450 * xdisp.c (start_display): If the character at POS is displayed
15451 via a display vector, reset IT->current.dpvec_index to zero.
15452 (try_window_reusing_current_matrix): If a line ends in a display
15453 vector or the next line starts in a display vector, continue
15454 redrawing the window even though the character position of
15455 start_row was reached.
15458 2011-10-18 Chong Yidong <cyd@gnu.org>
15460 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15461 with nobreak-char-display too.
15463 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15465 Fix part 3 of bug#9771.
15466 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15467 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15468 non-neutral characters if the current character is a paragraph
15469 separator (a.k.a. Newline). This avoids running the same
15470 expensive loop twice, once when we consume the preceding newline
15471 and the other time when the line actually needs to be displayed.
15472 Avoid the loop when we see neutrals on the base embedding level
15473 following a character whose directionality is the same as the
15474 paragraph's. This avoids running the expensive loop when a line
15475 ends in a long sequence of neutrals, like control characters.
15476 Add assertion against STRONG_AL type. Slightly rearrange code
15477 that determines the type of a neutral given the first non-neutral
15479 (bidi_level_of_next_char): Set next_en_pos to zero when
15480 invalidating its info.
15482 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15484 * xdisp.c (push_display_prop): Determine whether to record string
15485 or buffer position by IT->string, not by IT->method. Allow
15486 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15487 (move_it_vertically_backward): Don't look for character position
15488 immediately after the newline when in a continuation line.
15491 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15493 * window.c (coordinates_in_window): Rewrite and delabelize
15494 vertical border check. (Bug#5357) (Bug#9618)

15498 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15499 errors in XSetWindowBorder (bug#9310).
15501 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15503 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15504 avoid crash when xmalloc overrun checking is enabled.
15506 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15508 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15509 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15510 cursor motion with <left> and <right> arrow keys.
15512 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15513 some callers set that themselves.
15515 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15517 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15518 display string and the previous row comes from the same string and
15519 is empty. (Bug#9739) (Bug#9738)
15521 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15523 * doc.c (get_doc_string): Encode file name (bug#9735).

15527 * bidi.c (bidi_level_of_next_char):
15528 * xdisp.c (get_visually_first_element): Remove old incorrect
15529 comments regarding the Unicode Line Separator character.
15531 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15533 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>

15536 boundary if nzombies > MAX_ZOMBIES.
15537 * alloc.c (dump_zombies): Add missing format specifier.
15539 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15541 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15542 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15544 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15545 Some packages use them to denote characters with modifiers.
15547 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15549 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15550 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15551 matching a pp-number. Rename parameter var to var1.
15553 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15555 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15557 2011-10-08 Glenn Morris <rgm@gnu.org>
15559 * callint.c (Fcall_interactively): Give a more explicit error for the
15560 'c' case with a non-character input. (Bug#8479)
15562 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15564 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15566 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15567 lines that are hscrolled on the left.
15569 * dispnew.c (buffer_posn_from_coords): Account for a possible
15570 presence of header-line. (Bug#4426)
15572 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15574 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15575 Don't advertise functionality which we discourage or doesn't work.
15577 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15579 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15580 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15581 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15582 this makes Emacs dump core during garbage collection on rare
15583 occasions. sizeof is obviously inferior to offsetof here, so
15584 stick with offsetof.
15585 (GC_POINTER_ALIGNMENT): New macro.
15586 (mark_memory): Omit 3rd (offset) arg; caller changed.
15587 Don't assume EMACS_INT alignment is the same as pointer alignment.
15589 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15591 * keyboard.c (read_key_sequence_remapped): New var.
15592 (read_key_sequence): Compute remapping in the right buffer.
15593 (command_loop_1): Use read_key_sequence's remapping directly.
15595 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15597 * dired.c (file_name_completion): Don't expand file name.
15598 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15599 before checking file name handler.
15601 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15602 they've been requested explicitly (bug#9591).
15604 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15606 * keymap.c (Fsingle_key_description): Use make_specified_string
15607 instead of build_string to build string from push_key_description.
15610 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15612 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15613 This fixes a Y2038 bug on 64-bit hosts.
15614 * buffer.c (reset_buffer):
15615 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15616 (Fclear_buffer_auto_save_failure):
15617 Use 0, not -1, to represent an unset failure time, since time_t
15618 might not be signed.
15620 Remove dependency on glibc malloc internals.
15621 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15622 Move back here from lisp.h, but with their new implementations.
15623 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15624 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15625 * charset.c (charset_table_init): New static var.
15626 (syms_of_charset): Use it instead of xmalloc. This removes a
15627 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15628 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15629 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15630 Move back to alloc.c.
15631 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15632 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15634 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15636 * nsterm.m (windowDidResize): Call x_set_window_size only when
15637 ns_in_resize is true. Otherwise set pixelwidth/height and
15638 call change_frame_size (Bug#9628).
15640 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15642 Port --enable-checking=all to Fedora 14 x86-64.
15643 * charset.c (syms_of_charset): Also account for glibc malloc's
15644 internal overhead when calculating the initial malloc maximum.
15646 Port --enable-checking=all to Fedora 14 x86.
15647 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15649 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15650 (overrun_check_realloc, overrun_check_free):
15651 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15652 That way, xmalloc returns a properly-aligned pointer even if
15653 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15654 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15655 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15656 into account when calculating the initial malloc maximum.
15657 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15658 Move here from alloc.c, so that charset.c can use it too.
15659 Properly align; the old code wasn't right for common 32-bit hosts
15660 when configured with --enable-checking=all.
15661 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15662 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15664 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15666 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15669 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15671 * xdisp.c (compute_display_string_end): If there's no display
15672 string at CHARPOS, return -1.
15674 * bidi.c (bidi_fetch_char): When compute_display_string_end
15675 returns a negative value, treat the character as a normal
15676 character not covered by a display string. (Bug#9624)
15678 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15680 * lread.c (Fread_from_string): Fix typo in docstring.
15682 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15684 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15685 newline, reseat the iterator instead of bidi-iterating there one
15686 character at a time. (Bug#9610)
15687 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15688 TO_CHARPOS if the bidi iterator is at base embedding level.
15690 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15692 * lread.c (readevalloop): Use correct code for NBSP.
15693 (read1): Likewise. (Bug#9608)
15695 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15697 * dbusbind.c (Fdbus_register_signal): When service is not
15698 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15700 2011-09-25 Glenn Morris <rgm@gnu.org>
15702 * buffer.c (truncate-lines): Doc fix.
15704 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15706 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15707 (Fset_window_next_buffers): Doc fix.
15709 2011-09-24 Glenn Morris <rgm@gnu.org>
15711 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15713 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15715 Fix minor problems found by static checking.
15716 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
15717 * indent.c (Fvertical_motion): Fix == vs = typo.
15719 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15721 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15722 Default value is now t. Doc fix.
15724 * indent.c (Fvertical_motion): Compute and apply the overshoot
15725 logic when moving up, not only when moving down. Fix the
15726 confusing name and values of the it_overshoot_expected variable;
15727 logic changes accordingly. (Bug#9254) (Bug#9549)
15729 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15730 CHARPOS is covered by a display string which includes newlines.
15731 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15732 is covered by a display string with embedded newlines.
15734 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15736 * dbusbind.c (Fdbus_register_signal): Add match rule to
15737 Vdbus_registered_objects_table. (Bug#9581)
15738 (Fdbus_register_method, Vdbus_registered_objects_table):
15741 2011-09-24 Jim Meyering <meyering@redhat.com>
15743 do not ignore write error for any output size
15744 The previous change was incomplete.
15745 While it makes emacs --batch detect the vast majority of stdout
15746 write failures, errors were still ignored whenever the output size is
15747 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15748 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15749 && echo FAIL: ignored write error
15750 FAIL: ignored write error
15751 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15752 && echo FAIL: ignored write error
15753 FAIL: ignored write error
15754 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15756 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15758 * emacs.c (Fkill_emacs): In noninteractive mode exit
15759 non-successfully if a write error occurred on stdout. (Bug#9574)
15761 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15763 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15766 * dispextern.h (struct it): Update the comment documenting what
15769 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15771 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15772 a display string, extend search for cursor position to end of row.
15773 (find_row_edges): If the row ends in a newline from a display
15774 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15775 Handle the case of a display string with multiple newlines.
15776 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15777 non-empty line. Fixes confusing cursor motion with arrow keys at
15778 the beginning of a line that starts with whitespace.
15780 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15782 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15785 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15787 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15788 boolean (Bug#9154).
15790 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15792 * xdisp.c (display_line): Record maximum and minimum buffer
15793 positions even if no glyphs were produced (e.g., by a zero-width
15794 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15795 buffer positions that will be removed from the glyph row because
15797 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15798 column is beyond frame width: don't subtract 1 "pixel" when
15799 computing width of the stretch.
15800 (reseat_at_next_visible_line_start): Undo the change made on
15801 2011-09-17 that saved paragraph information and restored it after
15802 the call to `reseat'. (Bug#9545)
15804 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15806 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15807 and turn window cursor on if cleared (Bug#9415).
15809 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15811 * search.c (boyer_moore): Take unibyte characters from pattern
15812 literally. (Bug#9458)
15814 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15816 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
15818 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
15820 Fix minor problem found by static checking.
15821 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
15822 initialized, to pacify gcc -Wuninitialized.
15824 * fileio.c: Report proper errno when syscall falls.
15825 (Finsert_file_contents): Save and restore errno,
15826 so that report_file_error outputs the correct diagnostic.
15827 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15829 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15831 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15833 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15835 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15836 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
15838 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15840 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15841 about the current paragraph and restore it after the call to reseat.
15843 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15844 (bidi_find_paragraph_start): Search back for paragraph beginning
15845 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15846 (bidi_move_to_visually_next): Only trigger paragraph-related
15847 computations when the last character is a newline or at EOB, not
15848 just any NEUTRAL_B. (Bug#9470)
15850 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15851 truncated lines if point is covered by a display string. (Bug#9524)
15853 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15855 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15856 (cons_to_x_long): New function.
15857 (lisp_data_to_selection_data): Use it. Correct the test for
15858 short-versus-long data; it was negated. Break out of vector
15859 loop, for efficiency, when a long datum is discovered.
15861 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15863 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15865 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15867 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
15868 GCC PR/17406) by declaring this function with external scope.
15870 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15872 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
15873 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
15875 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
15877 * editfns.c (Fformat): Correctly handle text properties on "%%".
15879 2011-09-15 Eli Zaretskii <eliz@gnu.org>
15881 * xterm.c (x_draw_composite_glyph_string_foreground):
15882 * w32term.c (x_draw_composite_glyph_string_foreground):
15883 * term.c (encode_terminal_code):
15884 * composite.c (composition_update_it, get_composition_id):
15885 * xdisp.c (get_next_display_element)
15886 (fill_composite_glyph_string): Add comments about special meaning
15887 of TAB characters in a composition.
15889 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15891 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15892 This occurs when processing a multibyte format.
15893 Problem reported by Wolfgang Jenker.
15895 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15897 * xdisp.c (try_cursor_movement): Only check for exact match if
15898 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15900 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15902 Remove unused external symbols.
15903 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15904 * xdisp.c (calc_pixel_width_or_height): Now static.
15905 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
15906 * indent.c (check_display_width):
15907 * w32term.c: Fix comment to match code.
15908 * xterm.c, xterm.h (x_catching_errors): Remove.
15910 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15912 * xselect.c: Use signed conversions more consistently (Bug#9498).
15913 (selection_data_to_lisp_data): Assume incoming selection data are
15914 signed integers, not unsigned. This is to be consistent with
15915 outgoing selection data, which was modified to use signed integers
15916 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15917 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15918 expects long, not unsigned long.
15920 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15922 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15923 computation of loop end. Reported by Johan Bockgård
15926 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15928 * frame.c (Fother_visible_frames_p): Function deleted.
15930 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15932 * indent.c (compute_motion): Process display vector front to back
15933 rather than the other way around. (Bug#2496)
15935 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15937 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15939 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15941 * minibuf.c (Fread_from_minibuffer): Doc fix.
15943 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15945 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15946 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15948 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15950 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15951 value for non-existent files.
15953 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15955 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15956 set its "size" to -1. This will set the modtime_size field of
15957 the corresponding buffer to -1, which is what
15958 verify-visited-file-modtime expects for files that do not exist.
15961 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15963 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15965 * lisp.h: ... from here. push_key_description is no longer
15966 defined in keyboard.c, so its declaration should not be in
15967 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15968 logically belongs with push_key_description.
15970 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15972 * buffer.h: Include <sys/types.h> instead of <time.h>.
15973 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15974 Problem reported by Herbert J. Skuhra.
15976 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15978 * xml.c (parse_region): Make the parsing work for
15979 non-comment-starting XML files again (bug#9144).
15981 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15983 * image.c (gif_load): Fix calculation of bottom and right corner.
15986 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15988 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15989 redisplay in small windows.
15991 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15993 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15995 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15997 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15998 Operate on live windows only.
16000 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
16002 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
16004 2011-09-07 Eli Zaretskii <eliz@gnu.org>
16006 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
16007 only under bidi iteration.
16009 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
16011 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
16013 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16015 isnan: Fix porting problem to Solaris 10 with bundled gcc.
16016 Without this fix, the command to link temacs failed due to an
16017 undefined symbol __builtin_isnan. This is because
16018 /usr/include/iso/math_c99.h #defines isnan(x) to
16019 __builtin_isnan(x), but the bundled gcc, which identifies itself
16020 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
16022 * floatfns.c (isnan): #undef, and then #define to a clone of
16024 (Fisnan): Always define, since it's always available now.
16025 (syms_of_floatfns): Always define isnan at the Lisp level.
16027 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16029 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
16031 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16033 * fileio.c: Fix bugs with large file offsets (Bug#9428).
16034 The previous code assumed that file offsets (off_t values) fit in
16035 EMACS_INT variables, which is not true on typical 32-bit hosts.
16036 The code messed up by falsely reporting buffer overflow in cases
16037 such as (insert-file-contents "big" nil 1 2) into an empty buffer
16038 when "big" contains more than 2**29 bytes, even though this
16039 inserts just one byte and does not overflow the buffer.
16040 (Finsert_file_contents): Store file offsets as off_t
16041 values, not as EMACS_INT values. Check for overflow when
16042 converting between EMACS_INT and off_t. When checking for
16043 buffer overflow or for overlap, take the offsets into account.
16044 Don't use EMACS_INT for small values where int suffices.
16045 When checking for overlap, fix a typo: ZV was used where
16046 ZV_BYTE was intended.
16047 (Fwrite_region): Don't assume off_t fits into 'long'.
16048 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
16050 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
16052 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
16054 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16056 sprintf-related integer and memory overflow issues (Bug#9412).
16058 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
16059 (esprintf, exprintf, evxprintf): New functions.
16060 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
16061 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
16062 (modify_event_symbol): Do not assume that the length of
16063 name_alist_or_stem is safe to alloca and fits in int.
16064 (Fexecute_extended_command): Likewise for function name and binding.
16065 (Frecursion_depth): Wrap around reliably on integer overflow.
16066 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
16067 since some callers pass EMACS_INT values.
16068 (Fsingle_key_description): Don't crash if symbol name contains more
16069 than MAX_ALLOCA bytes.
16070 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
16071 (get_minibuffer): Arg is now EMACS_INT, not int.
16072 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
16073 (esprintf, exprintf, evxprintf): New decls.
16074 * window.h (command_loop_level, minibuf_level): Reflect API changes.
16076 * dbusbind.c (signature_cat): New function.
16077 (xd_signature, Fdbus_register_signal):
16078 Do not overrun buffer; instead, report string overflow.
16080 * dispnew.c (add_window_display_history): Don't overrun buffer.
16081 Truncate instead; this is OK since it's just a log.
16083 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
16084 even if the time zone offset is outlandishly large.
16085 Don't mishandle offset == INT_MIN.
16087 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
16088 when creating daemon; the previous buffer-overflow check was incorrect.
16090 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
16091 which has the guts of the old verror function.
16093 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
16094 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
16096 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
16097 (font_unparse_xlfd): Don't blindly alloca long strings.
16098 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
16099 fits in int, when using sprintf. Use single snprintf to count
16100 length of string rather than counting it via multiple sprintfs;
16101 that's simpler and more reliable.
16102 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
16103 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
16104 sprintf, in case result does not fit in int.
16106 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
16107 (fontset_from_font): Print it.
16109 * frame.c (tty_frame_count): Now printmax_t, not int.
16110 (make_terminal_frame, set_term_frame_name): Print it.
16111 (x_report_frame_params): In X, window IDs are unsigned long,
16112 not signed long, so print them as unsigned.
16113 (validate_x_resource_name): Check for implausibly long names,
16114 and don't assume name length fits in 'int'.
16115 (x_get_resource_string): Don't blindly alloca invocation name;
16116 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
16119 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
16120 (xg_check_special_colors, xg_set_geometry):
16121 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
16123 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
16124 Use esprintf, not sprintf, in case result does not fit in int.
16126 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16127 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
16128 it as a large positive number.
16129 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
16130 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16132 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
16133 in case result does not fit in int.
16135 * print.c (float_to_string): Detect width overflow more reliably.
16136 (print_object): Make sprintf buffer a bit bigger, to avoid potential
16137 buffer overrun. Don't assume list length fits in 'int'. Treat
16138 print length of 0 as 0, not as infinity; to be consistent with other
16139 uses of print length in this function. Don't overflow print length
16140 index. Don't assume hash table size fits in 'long', or that
16141 vectorlike size fits in 'unsigned long'.
16143 * process.c (make_process): Use printmax_t, not int, to format
16144 process-name gensyms.
16146 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
16148 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
16149 to avoid potential buffer overrun.
16151 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
16152 if X resource line is longer than 512 bytes.
16154 * xfns.c (x_window): Make sprintf buffer a bit bigger
16155 to avoid potential buffer overrun.
16157 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
16159 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
16161 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16163 Integer overflow fixes for scrolling, etc.
16164 Without these, Emacs silently mishandles large integers sometimes.
16165 For example, "C-u 4294967297 M-x recenter" was treated as if
16166 it were "C-u 1 M-x recenter" on a typical 64-bit host.
16168 * xdisp.c (try_window_id): Check Emacs fixnum range before
16169 converting to 'int'.
16171 * window.c (window_scroll_line_based, Frecenter):
16172 Check that an Emacs fixnum is in range before assigning it to 'int'.
16173 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
16174 values converted from Emacs fixnums.
16175 (Frecenter): Don't wrap around a line count if it is out of 'int'
16176 range; instead, treat it as an extreme value.
16177 (Fset_window_configuration, compare_window_configurations):
16178 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
16180 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
16181 that can exceed INT_MAX. Check that EMACS_INT value is in range
16182 before assigning it to the (possibly-narrower) index.
16183 (match_limit): Don't assume that a fixnum can fit in 'int'.
16185 * print.c (print_object): Use ptrdiff_t, not int, for index that can
16188 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
16189 (Fvertical_motion): Don't wrap around LINES values that don't fit
16190 in 'int'. Instead, treat them as extreme values. This is good
16191 enough for windows, which can't have more than INT_MAX lines anyway.
16193 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16195 * Require libxml/parser.h to avoid compilation warning.
16197 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
16199 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
16200 since this reportedly can destroy thread storage.
16202 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
16204 * syntax.c (find_defun_start): Update all cache variables if
16205 exiting early (Bug#9401).
16207 2011-08-30 Eli Zaretskii <eliz@gnu.org>
16209 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
16211 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
16212 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
16213 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
16215 * term.c (tty_append_glyph): New function.
16216 (produce_stretch_glyph): Static function and its prototype deleted.
16218 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
16221 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
16223 * image.c (parse_image_spec): Check for nonnegative, not for positive,
16224 when checking :margin (Bug#9390).
16225 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
16226 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
16227 so that the name doesn't mislead. All uses changed.
16229 2011-08-28 Johan Bockgård <bojohan@gnu.org>
16231 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
16234 2011-08-27 Eli Zaretskii <eliz@gnu.org>
16236 * xdisp.c (move_it_to): Don't bail out early when reaching
16237 position beyond to_charpos, if we are scanning backwards.
16238 (move_it_vertically_backward): When DY == 0, make sure we get to
16239 the first character in the line after the newline.
16241 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
16243 * ccl.c: Improve and simplify overflow checking (Bug#9196).
16244 (ccl_driver): Do not generate an out-of-range pointer.
16245 (Fccl_execute_on_string): Remove unnecessary check for
16246 integer overflow, noted by Stefan Monnier in
16247 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
16248 Remove a FIXME that didn't need fixing.
16249 Simplify the newly-introduced buffer reallocation code.
16251 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
16253 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
16255 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
16257 Integer and memory overflow issues (Bug#9196).
16259 * doc.c (get_doc_string): Rework so that
16260 get_doc_string_buffer_size is the actual buffer size, rather than
16261 being 1 less than the actual buffer size; this makes xpalloc more
16264 * image.c (x_allocate_bitmap_record, cache_image):
16265 * xselect.c (Fx_register_dnd_atom):
16266 Simplify previous changes by using xpalloc.
16268 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
16269 since either will do and ptrdiff_t is convenient with xpalloc.
16271 * charset.c (charset_table_size)
16272 (struct charset_sort_data.priority): Now ptrdiff_t.
16273 (charset_compare): Don't overflow if priorities differ greatly.
16274 (Fsort_charsets): Don't assume list length fits in int.
16275 Check for size-calculation overflow when allocating sort data.
16276 (syms_of_charset): Allocate an initial charset table that is
16277 just under 64 KiB, to avoid problems with glibc malloc and mmap.
16279 * cmds.c (internal_self_insert): Check for size-calculation overflow.
16281 * composite.h (struct composition.glyph_len): Now int, not unsigned.
16282 The actual value is always <= INT_MAX, and leaving it unsigned made
16283 overflow checking harder.
16285 * dispextern.h (struct glyph_matrix.rows_allocated)
16286 (struct face_cache.size): Now ptrdiff_t, for convenience in use
16287 with xpalloc. The values are still always <= INT_MAX.
16289 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
16291 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
16292 (SAFE_NALLOCA): New macro.
16294 * region-cache.c (struct boundary.pos, find_cache_boundary)
16295 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
16296 (set_cache_region, invalidate_region_cache)
16297 (revalidate_region_cache, know_region_cache, region_cache_forward)
16298 (region_cache_backward, pp_cache):
16299 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
16300 so that ptrdiff_t * can be passed to xpalloc.
16301 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
16302 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
16303 (pp_cache): Don't assume cache_len fits in int.
16304 * region-cache.h: Adjust extern decls to match.
16306 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
16307 EMACS_INT, since either will do, for xpalloc.
16309 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
16310 (xnmalloc, xnrealloc, xpalloc): New functions.
16312 * bidi.c (bidi_shelve_header_size): New constant.
16313 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
16314 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
16316 * bidi.c (bidi_cache_shrink):
16317 * buffer.c (overlays_at, overlays_in, record_overlay_string)
16319 Don't update size of array until after memory allocation succeeds,
16320 because xmalloc/xrealloc may not return.
16321 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16322 now that we have proper integer overflow checking.
16323 (record_overlay_string, overlay_strings): Catch overflows when
16324 calculating size of overlay_str_buf.
16326 * callproc.c (Fcall_process): Check for size overflow when
16327 calculating size of args2.
16328 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
16329 Normally we prefer signed values, but sticking with ptrdiff_t would
16330 require adding more-complicated checks.
16332 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16333 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
16334 Redo buffer-overflow calculations to avoid integer overflow.
16335 Add a FIXME comment where memory seems to be over-allocated.
16337 * character.c (Fstring): Check for size-calculation overflow.
16339 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
16340 unnecessary integer overflow. Check for size overflow.
16341 (encode_coding_object): Don't update size until xmalloc succeeds.
16343 * composite.c (get_composition_id): Check for overflow in glyph
16344 length calculations.
16346 Integer and memory overflow fixes for display code.
16347 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
16348 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
16349 (scrolling_window): Check for overflow in size calculations.
16350 (line_draw_cost, realloc_glyph_pool, add_row_entry):
16351 Don't assume glyph table len fits in int.
16352 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
16353 (row_table_size): Now ptrdiff_t, not int.
16354 (scrolling_window): Avoid overflow in size calculations.
16355 Don't update size until allocation succeeds.
16356 * fns.c (concat): Check for overflow in size calculations.
16357 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
16358 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
16359 (NEXT_ALMOST_PRIME_LIMIT): New constant.
16361 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
16362 (get_doc_string): Check for size calculation overflow.
16363 Don't update size until allocation succeeds.
16364 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
16365 EMACS_INT, where ptrdiff_t will do.
16366 (Fsubstitute_command_keys): Check for string overflow.
16368 * editfns.c (set_time_zone_rule): Don't assume environment length
16370 (message_length): Now ptrdiff_t, not int.
16371 (Fmessage_box): Don't update size until allocation succeeds.
16372 Don't assume message length fits in int.
16373 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16375 * emacs.c (main): Do not reallocate argv, since there is a null at
16376 the end that can be overwritten, and this way there's no need to
16377 worry about size-calculation overflow.
16378 (sort_args): Check for size-calculation overflow.
16380 * eval.c (init_eval_once, grow_specpdl): Don't update size until
16382 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
16384 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
16385 (x_set_scroll_bar_width, x_figure_window_size):
16386 Check for integer overflow.
16387 (x_set_alpha): Do not assume XINT fits in int.
16389 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
16390 This is for the members text_lines, text_cols, total_lines, total_cols,
16391 where the system imposes an 'int' limit.
16393 * fringe.c (Fdefine_fringe_bitmap):
16394 Don't update size until alloc works.
16396 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
16397 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
16399 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
16400 Check for size-calculation overflow.
16401 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
16402 do, as we prefer signed integers.
16403 (id_to_widget.max_size, id_to_widget.used)
16404 (xg_store_widget_in_map, xg_remove_widget_from_map)
16405 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
16406 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
16407 Use and return ptrdiff_t, not int.
16408 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
16409 * gtkutil.h: Change prototypes to match the above.
16411 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
16412 are duplicate now that they've been promoted to lisp.h.
16413 (x_allocate_bitmap_record, x_alloc_image_color)
16414 (make_image_cache, cache_image, xpm_load):
16415 Don't update size until alloc is done.
16416 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
16418 Check for size calculation overflow.
16419 (ct_colors_allocated_max): New constant.
16420 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
16423 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
16424 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
16425 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
16426 Use ptrdiff_t, not int, to count maps.
16427 (read_char_minibuf_menu_prompt): Check for overflow in size
16428 calculations. Don't update size until allocation succeeds.
16429 Redo calculations to avoid overflow.
16430 * keyboard.h: Change prototypes to match the above.
16432 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
16434 (current_minor_maps): Check for size calculation overflow.
16435 * keymap.h: Change prototypes to match the above.
16437 * lread.c (read1, init_obarray): Don't update size until alloc done.
16439 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
16440 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
16442 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
16443 Now ptrdiff_t, not int.
16444 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

16456 (Fset_match_data): Don't assume list lengths fit in 'int'.
16458 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
16459 for command line length. Do not attempt to address one before the
16460 beginning of an array, as that's not portable.
16462 * term.c (max_frame_lines): Remove; unused.
16463 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
16465 (encode_terminal_code, calculate_costs): Check for size
16466 calculation overflow.

16470 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
16472 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
16473 subtracting pointers.

16488 Use ptrdiff_t, not int, for sizes.
16489 (Finternal_make_lisp_face, cache_face):
16490 Check for size calculation overflow.
16491 (cache_face): Treat size calculation overflows as if they were
16492 memory exhaustion (the usual treatment), rather than aborting.
16494 * xfns.c (x_encode_text, x_set_name_internal)
16495 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16496 sizes, since they can exceed INT_MAX in size. Check for size
16497 calculation overflow.
16499 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
16500 (xg_select): Check for size calculation overflow.
16501 Don't update size until alloc done.
16503 * xrdb.c (get_environ_db): Don't assume path length fits in int,
16504 as sprintf is limited to int lengths.
16506 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
16507 (X_LONG_MIN): New macros.
16508 Use them to make the following changes clearer.
16509 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16510 This change doesn't affect the value now, but it may help remind
16511 future maintainers not to raise the value too much later.
16512 (SELECTION_QUANTUM): Remove, replacing with ...
16513 (selection_quantum): ... new function, which avoids overflow.
16515 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16516 assumption that selection length fits in 'int'.
16517 (x_reply_selection_request, x_handle_selection_request)
16518 (x_get_window_property, receive_incremental_selection)
16519 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)

16523 (receive_incremental_selection, x_property_data_to_lisp):
16524 Redo calculations to avoid overflow.
16525 (x_reply_selection_request): When sending hint, ceiling it at
16526 X_LONG_MAX rather than relying on wraparound overflow to send

16529 (lisp_data_to_selection_data, x_property_data_to_lisp):
16530 Check for size-calculation overflow.
16531 (x_get_window_property, receive_incremental_selection)

16533 Don't store size until memory allocation succeeds.
16534 (x_get_window_property): Plug memory leak on memory exhaustion.
16535 Don't double-block input; malloc is safe here. Don't assume 2**34
16536 - 4 fits in unsigned long. Add an xassert to check
16537 XGetWindowProperty overflow. Be more careful about overflow
16538 calculations, and distinguish size from memory overflow better.
16539 (receive_incremental_selection): When tracing, don't assume
16540 unsigned int is less than INT_MAX.
16541 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
16542 harmful) conversions of unsigned short to int.
16543 (lisp_data_to_selection_data): Don't assume that integers
16544 in the range -65535 through -1 fit in an X unsigned short.
16545 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16546 result parameters unless successful. Rely on cons_to_unsigned
16547 to report problems with elements; the old code wasn't right anyway.
16548 (x_check_property_data): Check for int overflow; we cannot use
16549 a wider type due to X limits.
16550 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
16552 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
16554 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)

16582 * lisp.h (hash_lookup, hash_put):
16583 * minibuf.c (Ftest_completion):
16584 Use ptrdiff_t for hash table indexes, not int (which is too
16585 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16586 32-bit --with-wide-int hosts).
16588 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16589 Add a FIXME comment about memory leaks.
16590 (syms_of_charset): Don't assume xmalloc returns.

16597 with outlandish widths.
16598 * character.h (sanitize_tab_width): Rename from sanitize_width,
16599 now that we have two such functions. All uses changed.

16617 * xterm.c: Don't go over XClientMessageEvent limit.
16618 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16619 (x_send_scroll_bar_event): Likewise. Check that the size does not
16620 exceed limits imposed by XClientMessageEvent, as well as the usual
16621 ptrdiff_t and size_t limits.
16623 * keyboard.c: Overflow, signedness and related fixes.
16624 (make_lispy_movement): Use same integer type in forward decl
16625 that is used in the definition.
16626 (read_key_sequence, keyremap_step):
16627 Change bufsize argument back to int, undoing my 2011-03-30 change.
16628 We prefer signed types, and int is wide enough here.
16629 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16630 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16631 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16632 length, not size_t. Use ptrdiff_t for index, not int.
16633 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16634 possibility of integer overflow.
16636 Overflow, signedness and related fixes for images.

16658 (lookup_image): Remove unnecessary tests.
16659 (xbm_image_p): Locals are now of int, not EMACS_INT,
16660 since parse_image_check makes sure they fit into int.
16661 (png_load, gif_load, svg_load_image):
16662 Prefer int to unsigned where either will do.
16663 (tiff_handler): New function, combining the cores of the
16664 old tiff_error_handler and tiff_warning_handler.
16665 This function is rewritten to use vsnprintf and thereby avoid
16666 stack buffer overflows. It uses only the features of vsnprintf
16667 that are common to both POSIX and native Microsoft.
16668 (tiff_error_handler, tiff_warning_handler): Use it.
16669 (tiff_load, gif_load, imagemagick_load_image):
16670 Don't assume :index value fits in 'int'.
16671 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16672 (imagemagick_load_image): Check that crop parameters fit into
16673 the integer types that MagickCropImage accepts. Don't assume
16674 Vimagemagick_render_type has a nonnegative value. Don't assume
16675 size_t fits in 'long'.
16676 (gs_load): Use printmax_t to print the widest integers possible.

16689 handle_single_display_spec, not just 1 or zero.
16690 (handle_single_display_spec): If the display spec is of the form
16691 `(space ...)', and specifies display in the text area, return 2
16693 (try_cursor_movement): Check for the need to scroll more
16694 accurately, and prefer exact match for point under bidi.
16695 Don't advance `row' beyond the last row of the window.

16712 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
16713 buffers, return left-to-right.
16714 (set_cursor_from_row): Consider candidate row a win if its glyph
16715 represents a newline and point is on that newline. Fixes cursor
16716 positioning on the newline at EOL of R2L text within L2R
16717 paragraph, and vice versa.
16718 (try_cursor_movement): Check continued rows, in addition to
16719 continuation rows. Fixes unwarranted scroll when point enters a
16720 continued line of R2L text within an L2R paragraph, or vice versa.
16721 (cursor_row_p): Consider the case of point being equal to
16722 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
16723 from the end of a short line to the beginning of a continued line
16724 of R2L text within L2R paragraph.

16751 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16752 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16753 candidate is selected by the mouse, and that candidate has a
16754 composed character under the mouse.
16756 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16757 coordinates reported by pos-visible-in-window-p for a composed
16758 character in column zero.
16760 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

16766 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
16767 consider it a hit if to_charpos is anywhere in the range of the
16768 composed buffer positions.
16770 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16772 * image.c (gif_load): Don't assume that each subimage has the same
16773 dimensions as the base image. Handle disposal method that is
16774 "undefined" by the gif spec (Bug#9335).
16776 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
16778 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

16788 a composition, take its buffer position from IT->cmp_it.charpos.
16789 Fixes cursor positioning at the beginning of a line that begins
16790 with a composed character.
16792 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16794 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16795 character bidirectional type, use STRONG_L instead. Fixes crashes
16796 in a buffer produced by `describe-categories'.
16798 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16799 members before the level stack, so they would be saved and
16800 restored when copying iterator state. Fixes incorrect reordering
16801 around TABs covered by display properties.
16803 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

16829 Fix memory allocation problems in Cygwin build (Bug#9273).
16831 * unexcw.c ( __malloc_initialized): Declare external variable.
16832 (fixup_executable): Force the dumped emacs to reinitialize malloc.
16834 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):

16875 * xdisp.c (move_it_in_display_line_to): Don't invoke
16876 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16877 ppos_it. Fixes vertical cursor motion when line beginning is
16878 covered by an image. (Bug#9296)
16880 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>

16889 the event loop. Get status from as_status (Bug#7276).
16891 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16892 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16893 the event loop (Bug#7276).
16895 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
16897 * gnutls.c (QCgnutls_bootprop_priority)
16898 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
16899 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
16900 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
16901 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
16902 (QCgnutls_bootprop_verify_hostname_error)
16903 (QCgnutls_bootprop_callbacks_verify): Rename from
16904 Qgnutls_bootprop_..., all uses changed.
16906 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
16909 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
16911 * xfaces.c (Qframe_set_background_mode): Now static.
16912 * dispextern.h (Qframe_set_background_mode): Remove decl.
16914 * process.c (Fnetwork_interface_info): Declare local only if needed.
16916 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
16918 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
16919 (Fnetwork_interface_list): Allocate in increments of bytes instead
16920 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16921 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16923 (struct ifflag_def): notrailers is smart on OSX.
16924 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16925 Get hardware address with getifaddrs if available.
16927 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16929 * xdisp.c (iterate_out_of_display_property): xassert that
16930 IT->position is set to within IT->object's boundaries. Break from
16931 the loop as soon as EOB is reached; avoids infloops in redisplay
16932 when IT->position is set up wrongly due to some bug.
16933 Set IT->current to match the bidi iterator unconditionally.
16934 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16935 entry. Force push_it to save on the stack the current
16936 buffer/string position, to be restored by pop_it. Fix flags in
16937 the iterator structure wrt the object coming from a display
16938 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16939 properties. (Bug#9284)
16941 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16943 * fontset.c (fontset_get_font_group): Add proper type checks.
16946 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16948 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
16949 and LC_VERSION_MIN_MACOSX.
16950 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
16951 (dump_it) [LC_FUNCTION_STARTS]: Use it.
16953 2011-08-08 Eli Zaretskii <eliz@gnu.org>
16955 * xdisp.c (forward_to_next_line_start): Allow to use the
16956 no-display-properties-and-no-overlays under bidi display.
16957 Set disp_pos in the bidi iterator to avoid searches for display
16958 properties and overlays.
16960 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16962 * editfns.c (Fset_time_zone_rule): Document relationship with the
16965 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
16966 the font entity extracted from the cache (Bug#8109).
16968 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
16970 * composite.c (autocmp_chars): Don't reset point. That is done by
16971 restore_point_unwind (Bug#5984).
16973 2011-08-07 Juri Linkov <juri@jurta.org>
16975 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16976 to show the arg `TIME' instead of `TIMEVAL'.
16978 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16980 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16981 display property strides EOL and includes a newline, as in
16982 longlines-mode. (Bug#9254)
16983 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16984 word-wrap under bidirectional display. (Bug#9224)
16986 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16987 is non-zero, even if the data buffer is NULL. Fixes a crash in
16988 vertical-motion with longlines-mode. (Bug#9254)
16990 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16992 * bidi.c <bidi_cache_total_alloc>: Now static.
16993 (bidi_initialize): Initialize bidi_cache_total_alloc.
16995 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16998 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16999 amount allocated this far in `bidi_cache_total_alloc'.
17000 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
17001 non-zero, only free the data buffer without restoring the cache
17002 contents. All callers changed.
17004 * dispextern.h (bidi_unshelve_cache): Update prototype.
17006 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
17007 (move_it_in_display_line, move_it_to)
17008 (move_it_vertically_backward, move_it_by_lines): Replace the call
17009 to xfree to an equivalent call to bidi_unshelve_cache.
17010 (move_it_in_display_line_to): Fix logic of returning
17011 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
17013 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17015 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
17016 came from a string character with a `cursor' property. (Bug#9229)
17018 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17020 * Makefile.in (LIB_PTHREAD): New variable.
17021 (LIBES): Add LIB_PTHREAD (Bug#9216).
17023 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
17024 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
17026 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
17028 * regex.c (re_iswctype): Remove some redundant boolean conversions.
17030 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17032 * xterm.c (x_find_topmost_parent): New function.
17033 (x_set_frame_alpha): Find topmost parent window with
17034 x_find_topmost_parent and set the property there also (bug#9181).
17035 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
17037 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
17039 * callproc.c (Fcall_process): Avoid vfork clobbering
17040 the local vars buffer, coding_systems, current_dir.
17042 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
17044 * keymap.c (Fmake_composed_keymap): Move to subr.el.
17046 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
17048 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
17049 so that it is not optimized away.
17051 * xdisp.c (compute_display_string_pos): Remove unused local.
17053 2011-08-02 Eli Zaretskii <eliz@gnu.org>
17055 Fix slow cursor motion and scrolling in large buffers with
17056 selective display, like Org Mode buffers. (Bug#9218)
17058 * dispextern.h (struct bidi_it): New member disp_prop_p.
17060 * xdisp.c: Remove one-slot cache of display string positions.
17061 (compute_display_string_pos): Accept an additional argument
17062 DISP_PROP_P; callers changed. Scan at most 5K characters forward
17063 for a display string or property. If found, set DISP_PROP_P
17066 * bidi.c (bidi_fetch_char): Accept an additional argument
17067 DISP_PROP_P, and pass it to compute_display_string_pos.
17068 Only handle text covered by a display string if DISP_PROP_P is returned
17069 non-zero. All callers of bidi_fetch_char changed.
17071 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
17073 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
17075 2010-12-03 Don March <don@ohspite.net>
17077 * keymap.c (Fdefine_key): Fix non-prefix key error message when
17078 last character M-[char] is translated to ESC [char] (bug#7541).
17080 2011-08-02 Kenichi Handa <handa@m17n.org>
17082 * lisp.h (uniprop_table): Extern it.
17084 * chartab.c (uniprop_table): Make it non-static.
17086 2011-08-01 Eli Zaretskii <eliz@gnu.org>
17088 * xdisp.c (forward_to_next_line_start): Accept additional argument
17089 BIDI_IT_PREV, and store into it the state of the bidi iterator had
17091 (reseat_at_next_visible_line_start): Use the bidi iterator state
17092 returned by forward_to_next_line_start to restore the state of
17093 it->bidi_it after backing up to previous newline. (Bug#9212)
17095 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
17097 * regex.c (re_comp): Protoize.
17098 (re_exec): Fix return type.
17099 (regexec): Fix type of `ret'. (Bug#9203)
17101 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17103 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
17104 This is needed if max-image-size is a floating-point number.
17106 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17108 * print.c (print_object): Print empty symbol as ##.
17110 * lread.c (read1): Read ## as empty symbol.
17112 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17114 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
17115 setting frame foreground color (Bug#9175).
17116 (x_set_background_color): Likewise.
17118 * nsmenu.m (-setText): Size tooltip dimensions precisely to
17119 contents (Bug#9176).
17120 (EmacsTooltip -init): Remove bezels and add shadows to
17123 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
17124 or scroll bar (Bug#8470).
17126 * nsfont.m (nsfont_open): Remove assignment to voffset and
17127 unnecessary vars hshink, expand, hd, full_height, min_height.
17128 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
17130 * nsterm.h (nsfont_info): Remove voffset field.
17132 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17134 Implement strike-through and overline on NextStep (Bug#8863).
17136 * nsfont.m (nsfont_open): Use underline position provided by font,
17137 instead of hard-coded value of 2.
17138 (nsfont_draw): Call ns_draw_text_decoration instead.
17140 * nsterm.h: Add declaration for ns_draw_text_decoration.
17142 * nsterm.m (ns_draw_text_decoration): New function for drawing
17143 underline, overline, and strike-through.
17144 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
17145 ns_draw_text_decoration. Change treatment of cursor drawing to
17146 accommodate underlining, etc.
17148 2011-07-28 Eli Zaretskii <eliz@gnu.org>
17150 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
17153 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17155 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
17156 Without this fix, if a signal arrives just after memory fills up,
17157 'malloc' might be invoked reentrantly.
17159 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
17160 In other words, assume that every image size is allowed, on non-X
17161 hosts. This assumption is probably wrong, but it lets Emacs compile.
17163 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17165 * regex.c (re_iswctype): Convert return values to boolean.
17167 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
17169 * xdisp.c (compute_display_string_pos): Don't use cached display
17170 string position if the buffer had its restriction changed.
17173 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17175 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17177 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17179 Integer signedness and overflow and related fixes. (Bug#9079)
17181 * bidi.c: Integer size and overflow fixes.
17182 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
17183 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
17184 (bidi_cache_find_level_change, bidi_cache_ensure_space)
17185 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
17186 (bidi_find_other_level_edge):
17187 Use ptrdiff_t instead of EMACS_INT where either will do.
17188 This works better on 32-bit hosts configured --with-wide-int.
17189 (bidi_cache_ensure_space): Check for size-calculation overflow.
17190 Use % rather than repeated addition, for better worst-case speed.
17191 Don't set bidi_cache_size until after xrealloc returns, because it
17193 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
17194 (bidi_cache_ensure_space): Also check that the bidi cache size
17195 does not exceed that of the largest Lisp string or buffer. See Eli
17196 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
17198 * alloc.c (__malloc_size_t): Remove.
17199 All uses replaced by size_t. See Andreas Schwab's note
17200 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
17202 * image.c: Improve checking for integer overflow.
17203 (check_image_size): Assume that f is nonnull, since
17204 it is always nonnull in practice. This is one less thing to
17205 worry about when checking for integer overflow later.
17206 (x_check_image_size): New function, which checks for integer
17207 overflow issues inside X.
17208 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
17209 This removes the need for a memory_full check.
17210 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
17211 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
17212 (xbm_read_bitmap_data): Change locals back to 'int', since
17213 their values must fit in 'int'.
17214 (xpm_load_image, png_load, tiff_load):
17215 Invoke x_create_x_image_and_pixmap earlier,
17216 to avoid much needless work if the image is too large.
17217 (tiff_load): Treat overly large images as if
17218 x_create_x_image_and_pixmap failed, not as malloc failures.
17219 (gs_load): Use x_check_image_size.
17221 * gtkutil.c: Omit integer casts.
17222 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
17223 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
17225 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
17227 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
17228 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
17229 would wrongly return t on a 64-bit host.
17231 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
17232 The plain *_OVERFLOW macros run afoul of GCC bug 49705
17233 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
17234 and therefore cause GCC to emit a bogus diagnostic in some cases.
17236 * image.c: Integer signedness and overflow and related fixes.
17237 This is not an exhaustive set of fixes, but it's time to
17238 record what I've got.
17239 (lookup_pixel_color, check_image_size): Remove redundant decls.
17240 (check_image_size): Don't assume that arbitrary EMACS_INT values
17241 fit in 'int', or that arbitrary 'double' values fit in 'int'.
17242 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
17243 (tiff_load, imagemagick_load_image):
17244 Check for overflow in size calculations.
17245 (x_create_x_image_and_pixmap): Remove unnecessary test for
17246 xmalloc returning NULL; that can't happen.
17247 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
17248 (xpm_color_bucket): Use better integer hashing function.
17249 (xpm_cache_color): Don't possibly over-allocate memory.
17250 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
17251 (gif_memory_source):
17252 Use ptrdiff_t, not int or size_t, to record sizes.
17253 (png_load): Don't assume values greater than 2**31 fit in 'int'.
17254 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
17255 either works, as we prefer signed integers.
17256 (tiff_read_from_memory, tiff_write_from_memory):
17257 Return tsize_t, not size_t, since that's what the TIFF API wants.
17258 (tiff_read_from_memory): Don't fail simply because the read would
17259 go past EOF; instead, return a short read.
17260 (tiff_load): Omit no-longer-needed casts.
17261 (Fimagemagick_types): Don't assume size fits into 'int'.
17263 Improve hashing quality when configured --with-wide-int.
17264 * fns.c (hash_string): New function, taken from sxhash_string.
17265 Do not discard information about ASCII character case; this
17266 discarding is no longer needed.
17267 (sxhash-string): Use it. Change sig to match it. Caller changed.
17268 * lisp.h: Declare it.
17269 * lread.c (hash_string): Remove, since we now use fns.c's version.
17270 The fns.c version returns a wider integer if --with-wide-int is
17271 specified, so this should help the quality of the hashing a bit.
17273 * emacs.c: Integer overflow minor fix.
17274 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
17275 Define only if GNU_LINUX.
17276 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
17278 * dispnew.c: Integer signedness and overflow fixes.
17279 Remove unnecessary forward decls, that were a maintenance hassle.
17280 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
17282 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
17283 (scrolling_window): Use ptrdiff_t, not int, for byte count.
17284 (prepare_desired_row, line_draw_cost):
17285 Use int, not unsigned, where either works.
17286 (save_current_matrix, restore_current_matrix):
17287 Use ptrdiff_t, not size_t, where either works.
17288 (init_display): Check for overflow more accurately, and without
17289 relying on undefined behavior.
17291 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
17292 Remove, replacing with the new symbols in lisp.h. All uses changed.
17293 * fileio.c (make_temp_name):
17294 * filelock.c (lock_file_1, lock_file):
17295 * xdisp.c (message_dolog):
17296 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
17297 Use pMd etc. instead.
17298 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
17299 replacing the pWIDE etc. symbols removed from editfns.c.
17301 * keyboard.h (num_input_events): Now uintmax_t.
17302 This is (very slightly) less likely to mess up due to wraparound.
17305 * buffer.c: Integer signedness fixes.
17306 (alloc_buffer_text, enlarge_buffer_text):
17307 Use ptrdiff_t rather than size_t when either will do, as we prefer
17310 * alloc.c: Integer signedness and overflow fixes.
17311 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
17312 (__malloc_size_t): Default to size_t, not to int.
17313 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
17314 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17315 Prefer ptrdiff_t to size_t when either would do, as we prefer
17317 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17318 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17319 Now const. Initialize with values that are in range even if char
17321 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17322 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17323 These functions do the right thing with sizes > 2**32.
17324 (check_depth): Now ptrdiff_t, not int.
17325 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17326 Adjust to new way of storing sizes. Check for size overflow bugs
17328 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17329 slightly wrong anyway, as it missed one instance of
17330 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17331 (refill_memory_reserve): Omit needless cast to size_t.
17332 (mark_object_loop_halt): Mark as externally visible.
17334 * xselect.c: Integer signedness and overflow fixes.
17335 (Fx_register_dnd_atom, x_handle_dnd_message):
17336 Use ptrdiff_t, not size_t, since we prefer signed.
17337 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17338 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17339 x_dnd_atoms_size and x_dnd_atoms_length.
17341 * doprnt.c: Prefer signed to unsigned when either works.
17343 * doprnt.c (doprnt):
17345 * xdisp.c (vmessage):
17346 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17347 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17348 prefer signed arithmetic to avoid comparison confusion.
17349 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17350 but is a bit tricky.
17352 Assume freestanding C89 headers, string.h, stdlib.h.
17353 * data.c, doprnt.c, floatfns.c, print.c:
17354 Include float.h unconditionally.
17355 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17356 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17357 * regex.c: Likewise for stddef.h, string.h.
17358 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17359 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17360 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17361 (STDC_HEADERS): Remove obsolete defines.
17362 * sysdep.c: Include limits.h unconditionally.
17364 Assume support for memcmp, memcpy, memmove, memset.
17365 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17366 * regex.c (memcmp, memcpy):
17367 Remove; we assume C89 now.
17369 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17370 (__malloc_safe_bcopy): Remove; no longer needed.
17372 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17373 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17374 well either way, and we prefer signed to unsigned.
17376 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17378 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17379 closes the connection while we're reading (bug#9182).
17381 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17383 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17384 are specified (Bug#9168).
17386 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17388 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17389 Found by GCC static checking and --with-wide-int on a 32-bit host.
17391 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17393 * xdisp.c (compute_display_string_pos): Fix logic of caching
17394 previous display string position. Initialize cached_prev_pos to
17395 -1. Fixes slow-down at the beginning of a buffer.
17397 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17399 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17400 for attrs[LFACE_FONTSET_INDEX].
17402 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17404 * xml.c (parse_region): Remove unused local
17405 that was recently introduced.
17407 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17409 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17410 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17412 * xdisp.c (move_it_in_display_line_to): Record the best matching
17413 position for TO_CHARPOS while scanning the line, and restore it on
17414 exit if none of the characters scanned was an exact match.
17415 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17416 when exact match is impossible due to invisible text, and the
17417 lines are truncated.
17419 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17421 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17424 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17426 Fix a significant slow-down of cursor motion with C-n, C-p,
17427 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17428 auto-repeat under bidi redisplay in fontified buffers.
17429 * xdisp.c (compute_stop_pos_backwards): New function.
17430 (next_element_from_buffer): Call compute_stop_pos_backwards to
17431 find a suitable prev_stop when we find ourselves before
17433 (reseat): Don't look for prev_stop, as that could mean a very long
17435 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17436 <cached_disp_overlay_modiff>: Cache for last found display string
17438 (compute_display_string_pos): Return the cached position if asked
17439 about the same buffer in the same area of character positions, and
17440 the buffer wasn't changed since the time the display string
17441 position was cached.
17443 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17445 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17446 is an integer, which is important for empty lines. (Bug#9149)
17448 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17450 * frame.c (Fmodify_frame_parameters): In tty case, update the
17451 default face if necessary (Bug#4238).
17453 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17455 * editfns.c (Fstring_to_char): No need to explain what a character
17456 is in the docstring (Bug#6576).
17458 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17460 * xml.c (parse_region): Make sure we always return a tree.
17462 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17464 * xml.c (parse_region): If a document contains only comments,
17467 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17469 * xml.c (make_dom): Return comments, too.
17471 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17474 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17475 and the surrounding thread.
17476 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17477 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17478 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17480 * s/openbsd.h (BROKEN_SIGIO): Define.
17481 * unexelf.c (unexec) [__OpenBSD__]:
17482 Don't update the .mdebug section of the Alpha COFF symbol table.
17484 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17486 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17489 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17491 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17492 This fixes some race conditions on the permissions of any newly
17495 * alloc.c (valid_pointer_p): Use pipe, not open.
17496 This fixes some permissions issues when debugging.
17498 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17499 If fchown fails to set both uid and gid, try to set just gid,
17500 as that is sometimes allowed. Adjust the file's mode to eliminate
17501 setuid or setgid bits that are inappropriate if fchown fails.
17503 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17505 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
17506 to compare Lisp_Objects.
17507 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
17508 global_gnutls_log_level, don't mistake it for a Lisp_Object.
17509 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
17511 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17513 * lread.c (read_integer): Unread even EOF character.
17514 (read1): Likewise. Properly record start position of symbol.
17516 * lread.c (read1): Read `#:' as empty uninterned symbol if no
17517 symbol character follows.
17519 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17521 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17522 This works around a problem with the previous change to Fcopy_file.
17523 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17524 and without this change, GCC might complain about discarding
17525 fchown's return value.
17527 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17529 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17531 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17533 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17535 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17537 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17538 it's used from the C level.
17540 * process.c: Use the same condition for POLL_FOR_INPUT in both
17541 keyboard.c and process.c (bug#1858).
17543 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17545 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17546 (Fgnutls_boot): Use it.
17548 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17550 * doc.c (Fsubstitute_command_keys): Revert last change.
17552 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17554 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17555 quotes the next character, and doesn't affect other longer
17556 sequences (bug#8935).
17558 * lread.c (syms_of_lread): Clarify that is isn't only
17559 `eval-buffer' and `eval-defun' that's affected by
17560 `lexical-binding' (bug#8460).
17562 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17564 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17565 bidi redisplay when a line includes both an image and is truncated.
17567 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17569 Fix minor problems found by static checking.
17570 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17571 (elsz): Now a signed constant, not a size_t var. We prefer signed
17572 types to unsigned, to avoid integer comparison confusion. Without
17573 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17574 "cannot optimize loop, the loop counter may overflow", a symptom
17576 * indent.c (Fvertical_motion): Mark locals as initialized.
17577 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17579 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
17581 * search.c (Fre_search_backward): Mention `case-fold-search' in
17582 all the re_search_* functions (bug#8138).
17584 * keyboard.c (Fopen_dribble_file): Document when the file is

17597 bidi_it->string.schars.
17598 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
17599 NULL (avoids a crash in bidi_paragraph_init).
17600 Initialize itb.string.lstring.
17601 (init_iterator): Call bidi_init_it only of a valid
17602 buffer position was specified. Initialize paragraph_embedding to
17604 (reseat_to_string): Initialize the bidi iterator.
17605 (display_string): If we need to ignore text properties of
17606 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17607 original value of -1 will not work with bidi.)
17608 (compute_display_string_pos): First arg is now struct
17609 `text_pos *'; all callers changed. Support display properties on
17611 (compute_display_string_end): Support display properties on Lisp
17613 (init_iterator, reseat_1, reseat_to_string): Initialize the
17614 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
17615 when iterating on a string not from display properties).
17616 (compute_display_string_pos, compute_display_string_end):
17617 Fix calculation of the object to scan. Fixes an error when using
17619 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
17620 base_level_stop; instead, set base_level_stop to BEGV.
17621 Fixes crashes in vertical-motion.
17622 (next_element_from_buffer): Improve commentary for when
17623 the iterator is before prev_stop.
17624 (init_iterator): Initialize bidi_p from the default value of
17625 bidi-display-reordering, not from buffer-local value. Use the
17626 buffer-local value only if initializing for buffer iteration.
17627 (handle_invisible_prop): Support invisible properties on strings
17628 that are being bidi-reordered.
17629 (set_iterator_to_next): Support bidi reordering of C strings and
17631 (next_element_from_string): Support bidi reordering of Lisp
17633 (handle_stop_backwards): Support Lisp strings as well.
17634 (display_string): Support display of R2L glyph rows.
17635 Use IT_STRING_CHARPOS when displaying from a Lisp string.
17636 (init_iterator): Don't initialize it->bidi_p for strings
17638 (reseat_to_string): Initialize it->bidi_p for strings here.
17639 (next_element_from_string, next_element_from_c_string)
17640 (next_element_from_buffer): Add xassert's for correspondence
17641 between IT's object being iterated and it->bidi_it.string

17644 (next_element_from_c_string): Handle the case of the first string
17645 character that is not the first one in the visual order.
17646 (get_visually_first_element): New function, refactored from common
17647 parts of next_element_from_buffer, next_element_from_string, and
17648 next_element_from_c_string.
17649 (tool_bar_lines_needed, redisplay_tool_bar)
17650 (display_menu_bar): Force left-to-right direction. Add a FIXME
17651 comment for making that be controlled by a user option.
17652 (push_it, pop_it): Save and restore the state of the
17653 bidi iterator. Save and restore the bidi_p flag.
17654 (pop_it): Iterate out of display property for string iteration as
17656 (iterate_out_of_display_property): Support iteration over strings.
17657 (handle_single_display_spec): Set up it->bidi_it for iteration
17658 over a display string, and call bidi_init_it.
17659 (handle_single_display_spec, next_overlay_string)
17660 (get_overlay_strings_1, push_display_prop): Set up the bidi
17661 iterator for displaying display or overlay strings.
17662 (forward_to_next_line_start): Don't use the shortcut if
17664 (back_to_previous_visible_line_start): If handle_display_prop
17665 pushed the iterator stack, restore the internal state of the bidi
17666 iterator by calling bidi_pop_it same number of times.
17667 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
17668 and we are bidi-iterating, don't decrement the iterator position;
17669 instead, set the first_elt flag in the bidi iterator, to produce
17671 (reseat_1): Remove redundant setting of string_from_display_prop_p.
17672 (push_display_prop): xassert that we are iterating a buffer.
17673 (push_it, pop_it): Save and restore paragraph_embedding member.
17674 (handle_single_display_spec, next_overlay_string)
17675 (get_overlay_strings_1, reseat_1, reseat_to_string)
17676 (push_display_prop): Set up the `unibyte' member of bidi_it.string
17677 correctly. Don't assume unibyte strings are not bidi-reordered.
17678 (compute_display_string_pos)
17679 (compute_display_string_end): Fix handling the case of C string.
17680 (push_it, pop_it): Save and restore from_disp_prop_p.

17685 popping after iteration over a string that came from a display
17686 property. Fix a typo in popping stretch info. Add an assertion
17687 for verifying that the iterator position is in sync with the bidi
17689 (handle_single_display_spec, get_overlay_strings_1)
17690 (push_display_prop): Fix initialization of paragraph direction for
17691 string when that of the parent object is not yet determined.
17692 (reseat_1): Call bidi_init_it to resync the bidi
17693 iterator with IT's position. (Bug#7616)
17694 (find_row_edges): If ROW->start.pos gives position
17695 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
17696 (handle_stop, back_to_previous_visible_line_start, reseat_1):
17697 Reset the from_disp_prop_p flag.
17698 (SAVE_IT, RESTORE_IT): New macros.

17700 (back_to_previous_visible_line_start)
17701 (move_it_in_display_line_to, move_it_in_display_line)
17702 (move_it_to, move_it_vertically_backward, move_it_by_lines)
17703 (try_scrolling, redisplay_window, display_line): Use them when
17704 saving a temporary copy of the iterator and restoring it back.
17705 (back_to_previous_visible_line_start, reseat_1)
17706 (init_iterator): Empty the bidi cache "stack".
17707 (move_it_in_display_line_to): If iterator ended up at
17708 EOL, but we never saw any buffer positions smaller than
17709 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
17710 motion in bidi-reordered lines.
17711 (move_it_in_display_line_to): Record prev_method and prev_pos
17712 immediately before the call to set_iterator_to_next. Fixes cursor
17713 motion in bidi-reordered lines with stretch glyphs and strings
17714 displayed in margins. (Bug#8133) (Bug#8867)
17715 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
17717 (pos_visible_p): Support positions in bidi-reordered lines.
17718 Save and restore bidi cache.
17720 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
17721 (bidi_paragraph_info): Delete unused struct.
17722 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
17723 (bidi_cache_start): New variable.
17724 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not

17732 (bidi_fetch_char): Accept new argument STRING; all callers
17733 changed. Support iteration over a string. Support strings with
17734 display properties. Support unibyte strings. Fix the type of
17735 `len' according to what STRING_CHAR_AND_LENGTH expects.
17736 (bidi_paragraph_init, bidi_resolve_explicit_1)
17737 (bidi_resolve_explicit, bidi_resolve_weak)
17738 (bidi_level_of_next_char, bidi_move_to_visually_next):
17739 Support iteration over a string.
17740 (bidi_set_sor_type, bidi_resolve_explicit_1)
17741 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
17742 can now be zero (for strings); special values 0 and -1 were
17743 changed to -1 and -2, respectively.
17744 (bidi_char_at_pos): New function.
17745 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):
17746 Call it instead of FETCH_MULTIBYTE_CHAR.

17756 (bidi_initialize): Initialize the bidi cache start stack pointer.
17757 (bidi_cache_ensure_space): New function, refactored from part of

17831 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
17833 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
17834 The old code sometimes used this field without initializing it.
17836 * alloc.c (gc_sweep): Don't read past end of array.
17837 In theory, the old code could also have corrupted Emacs internals,
17838 though it'd be very unlikely.

18101 (clone_per_buffer_values): Don't assume that

18103 This isn't true in general, and it's particularly not true
18104 if Emacs is configured with --with-wide-int.
18105 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
18106 New macros, used in the buffer.c change.

18142 Random fixes. E.g., (random) never returned negative values.
18143 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
18144 subseconds part to the entropy, as that's a bit more random.
18145 Prefer signed to unsigned, since the signedness doesn't matter and
18146 in general we prefer signed. When given a limit, use a
18147 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
18148 latter isn't right if USE_2_TAGS_FOR_INTS.
18149 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
18150 not 0..VALMASK. Don't discard "excess" bits that random () returns.

18160 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
18162 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
18163 This is more efficient than Ffile_directory_p and avoids a minor race.
18165 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
18167 * buffer.c (Foverlay_put): Say what the return value is
18170 * fileio.c (barf_or_query_if_file_exists): Check first if the file
18171 is a directory before asking whether to use the file name
18173 (barf_or_query_if_file_exists): Make the "File is a directory"
18174 error be more correct.
18176 * fns.c (Frequire): Remove the mention of the .gz files, since
18177 that's installation-specific, but keep the mention of
18178 `get-load-suffixes'.

18182 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

18190 Qgnutls_bootprop_verify_error (which is no longer used).
18192 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
18193 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
18194 Also (re)move comments that are misplaced or no longer relevant.
18196 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
18198 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

18295 * eval.c (struct backtrace): Simplify and port the data structure.
18296 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
18297 signed bit field, as this assumption is not portable and it makes
18298 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
18299 "char debug_on_exit : 1" as this is not portable either; instead,
18300 use the portable "unsigned int debug_on_exit : 1". Remove unused
18301 member evalargs. Remove obsolete comments about cc bombing out.

18375 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
18376 and use min_width/height from frames size_hint to set
18377 min_width/height (Bug#8919).

18491 (read1): Check for integer overflow in radices, and in
18492 read-circle numbers.

18536 on undefined behavior with wrong number of arguments.
18537 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18538 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18539 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18540 since we're not interested in debugging glyphs with old libraries.
18541 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18542 GCC 4.6.0's static checking.

18584 (x_session_initialize): Do not assume string length fits in int.
18586 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.

18632 Don't assume pid_t and time_t fit in unsigned long.
18633 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18634 (current_lock_owner): Prefer signed type for sizes.
18635 Use memcpy, not strncpy, where memcpy is what is really wanted.
18636 Don't assume (via atoi) that time_t and pid_t fit in int.
18637 Check for time_t and/or pid_t out of range, e.g., via a network share.
18638 Don't alloca where an auto var works fine.

18651 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
18653 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
18654 We prefer signed integers, even for size calculations.
18656 * emacs.c: Don't assume string length fits in 'int'.
18657 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
18658 (main): Don't invoke strlen when not needed.
18660 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
18661 (XD_DEBUG_MESSAGE): Don't waste a byte.
18663 * callproc.c (getenv_internal_1, getenv_internal)
18664 (Fgetenv_internal):
18665 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18667 * lread.c (invalid_syntax): Omit length argument.
18668 All uses changed. This doesn't fix a bug, but it simplifies the
18669 code away from its former Hollerith-constant appearance, and it's
18670 one less 'int' to worry about when looking at integer-overflow issues.
18671 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18673 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18674 This didn't break anything, but it didn't help either.
18675 It's confusing to put a bogus integer in a place where the actual
18676 value does not matter.
18677 (LIST_END_P): Remove unused macro and its bogus comment.
18678 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18680 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18681 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18683 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18684 We prefer signed types, and the value cannot exceed the EMACS_INT
18685 range anyway (because otherwise the length would not be representable).
18686 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18687 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18688 This avoids a GCC warning when WIDE_EMACS_INT.
18690 * indent.c (sane_tab_width): New function.
18691 (current_column, scan_for_column, Findent_to, position_indentation)
18692 (compute_motion): Use it. This is just for clarity.
18693 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18695 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
18697 * lisp.h (lint_assume): New macro.
18698 * composite.c (composition_gstring_put_cache):
18699 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18701 * editfns.c, insdel.c:
18702 Omit unnecessary forward decls, to simplify future changes.
18704 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18706 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18708 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18709 Use much-faster test for byte-length change.
18710 Don't assume string byte-length fits in 'int'.
18711 Check that character arg fits in 'int'.
18712 (mapcar1): Declare byte as byte, for clarity.
18714 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18716 * fns.c (concat): Catch string overflow earlier.
18717 Do not rely on integer wraparound.
18719 * dispextern.h (struct it.overlay_strings_charpos)
18720 (struct it.selective): Now EMACS_INT, not int.
18721 * xdisp.c (forward_to_next_line_start)
18722 (back_to_previous_visible_line_start)
18723 (reseat_at_next_visible_line_start, next_element_from_buffer):
18724 Don't arbitrarily truncate the value of 'selective' to int.
18726 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18728 * composite.c: Don't truncate sizes to 'int'.
18729 (composition_gstring_p, composition_reseat_it)
18730 (composition_adjust_point): Use EMACS_INT, not int.
18731 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18732 not EMACS_UINT, for indexes.
18734 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18736 * buffer.c: Include <verify.h>.
18737 (struct sortvec.priority, struct sortstr.priority):
18738 Now EMACS_INT, not int.
18739 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18740 (struct sortstr.size, record_overlay_string)
18741 (struct sortstrlist.size, struct sortlist.used):
18742 Don't truncate size to int.
18743 (record_overlay_string): Check for size-calculation overflow.
18744 (init_buffer_once): Check at compile-time, not run-time.
18746 2011-06-22 Jim Meyering <meyering@redhat.com>
18748 Don't leak an XBM-image-sized buffer
18749 * image.c (xbm_load): Free the image buffer after using it.
18751 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18754 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18755 that Sun C diagnosed.
18756 * fns.c (secure_hash): Fix pointer signedness issue.
18757 * intervals.c (static_offset_intervals): New function.
18758 (offset_intervals): Use it.
18760 2011-06-21 Leo Liu <sdl.web@gmail.com>
18763 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18766 * fns.c (secure_hash): Rename from crypto_hash_function and change
18767 the first arg to accept symbols.
18768 (Fsecure_hash): New primitive.
18769 (syms_of_fns): New symbols.
18771 2011-06-20 Deniz Dogan <deniz@dogan.se>
18773 * process.c (Fset_process_buffer): Clarify return value in
18776 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18778 * dispnew.c (add_window_display_history): Use BVAR.
18780 * xdisp.c (debug_method_add): Use BVAR.
18781 (check_window_end, dump_glyph_matrix, dump_glyph)
18782 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18784 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18787 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18788 check till after the cache is created in init_frame_faces.
18790 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18792 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18794 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18796 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18797 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18798 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18800 Improve buffer-overflow checking (Bug#8873).
18801 * fileio.c (Finsert_file_contents):
18802 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18803 Remove the old (too-loose) buffer overflow checks.
18804 They weren't needed, since make_gap checks for buffer overflow.
18805 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18806 The old code merely checked for Emacs fixnum overflow, and relied
18807 on undefined (wraparound) behavior. The new code avoids undefined
18808 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18810 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18811 Tune. Don't use wider integers than needed. Don't use alloca.
18812 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18814 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18816 * insdel.c, lisp.h (buffer_overflow): New function.
18817 (insert_from_buffer_1, replace_range, replace_range_2):
18818 * insdel.c (make_gap_larger):
18819 * editfns.c (Finsert_char):
18820 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18822 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18824 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18826 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18828 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18829 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18831 * fileio.c: Don't assume EMACS_INT fits in off_t.
18832 (emacs_lseek): New static function.
18833 (Finsert_file_contents, Fwrite_region): Use it.
18834 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18836 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18838 * fns.c: Don't overflow int when computing a list length.
18839 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18840 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18841 truncation on 64-bit hosts. Check for QUIT every
18842 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18843 faster and is responsive enough.
18844 (Flength): Report an error instead of overflowing an integer.
18845 (Fsafe_length): Return a float if the value is not representable
18846 as a fixnum. This shouldn't happen except in contrived situations.
18847 (Fnthcdr, Fsort): Don't assume list length fits in int.
18848 (Fcopy_sequence): Don't assume vector length fits in int.
18850 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18851 (header_size, word_size): New constants.
18852 (allocate_vectorlike): Don't check size overflow here.
18853 (allocate_vector): Check it here instead, since this is the only
18854 caller of allocate_vectorlike that could cause overflow.
18855 Check that the new vector's length is representable as a fixnum.
18857 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18858 The previous code was bogus. For example, next_almost_prime (32)
18859 returned 39, which is undesirable as it is a multiple of 3; and
18860 next_almost_prime (24) returned 25, which is a multiple of 5 so
18861 why was the code bothering to check for multiples of 7?
18863 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18865 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18867 Variadic C functions now count arguments with ptrdiff_t.
18868 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18869 Back then I didn't know that the Emacs coding style prefers signed int.
18870 Also, in the meantime I found a few more instances where arguments
18871 were being counted with int, which may truncate counts on 64-bit
18872 machines, or EMACS_INT, which may be unnecessarily wide.
18873 * lisp.h (struct Lisp_Subr.function.aMANY)
18874 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18875 Arg counts are now ptrdiff_t, not size_t.
18876 All variadic functions and their callers changed accordingly.
18877 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18878 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18879 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18880 * callint.c (Fcall_interactively): Check arg count for overflow,
18881 to avoid potential buffer overrun. Use signed char, not 'int',
18882 for 'varies' array, so that we needn't bother to check its size
18883 calculation for overflow.
18884 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18885 * eval.c (apply_lambda):
18886 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18887 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18888 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18890 * callint.c (Fcall_interactively): Don't use index var as event count.
18892 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18893 * mem-limits.h (SIZE): Remove; no longer used.
18895 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18897 Remove unnecessary casts.
18898 * xterm.c (x_term_init):
18899 * xfns.c (x_set_border_pixel):
18900 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18901 These aren't needed now that we assume ANSI C.
18903 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18904 It's more likely to cause problems (due to unsigned overflow)
18907 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18909 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18911 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18913 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18915 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18917 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18919 GLYPH_CODE_FACE returns EMACS_INT, not int.
18920 * dispextern.h (merge_faces):
18921 * xfaces.c (merge_faces):
18922 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18923 Don't assume EMACS_INT fits in int.
18925 * character.h (CHAR_VALID_P): Remove unused parameter.
18926 * fontset.c, lisp.h, xdisp.c: All uses changed.
18928 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18930 * fns.c (concat): Minor tuning based on overflow analysis.
18931 This doesn't fix any bugs. Use int to hold character, instead
18932 of constantly refetching from Emacs object. Use XFASTINT, not
18933 XINT, for value known to be a character. Don't bother comparing
18934 a single byte to 0400, as it's always less.
18936 * floatfns.c (Fexpt):
18937 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18939 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18942 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18944 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18945 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18946 incorrectly succeed when S was a string, because 4294967386 was
18947 truncated before it was used.
18949 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18950 Otherwise, an out-of-range integer could cause undefined behavior
18953 * composite.c: Use int, not EMACS_INT, for characters.
18954 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18955 EMACS_INT, for values that are known to be in character range.
18956 This doesn't fix any bugs but is the usual style inside Emacs and
18957 may generate better code on 32-bit machines.
18959 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18960 This is for reasons similar to the recent CHAR_STRING fix.
18961 * charset.c (Fencode_char): Check that character arg is actually
18962 a character. Pass an int to ENCODE_CHAR.
18963 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18964 wider than 'int', as a compile-time check to prevent future regressions
18967 * character.c (char_string): Remove unnecessary casts.
18969 Make sure a 64-bit char is never passed to CHAR_STRING.
18970 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18971 by silently ignoring the top 32 bits, allowing some values
18972 that were far too large to be valid characters.
18973 * character.h: Include <verify.h>.
18974 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18975 arguments are no wider than unsigned, as a compile-time check
18976 to prevent future regressions in this area.
18978 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18979 (Fsubst_char_in_region):
18981 * xdisp.c (decode_mode_spec_coding):
18982 Adjust to CHAR_STRING's new requirement.
18983 * editfns.c (Finsert_char, Fsubst_char_in_region):
18984 * fns.c (concat): Check that character args are actually
18985 characters. Without this test, these functions did the wrong
18986 thing with wildly out-of-range values on 64-bit hosts.
18988 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18989 These casts should not be needed on 32-bit hosts, either.
18990 * keyboard.c (read_char):
18991 * lread.c (Fload): Remove casts to unsigned.
18993 * lisp.h (UNSIGNED_CMP): New macro.
18994 This fixes comparison bugs on 64-bit hosts.
18995 (ASCII_CHAR_P): Use it.
18996 * casefiddle.c (casify_object):
18997 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18998 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18999 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
19000 * dispextern.h (FACE_FROM_ID):
19001 * keyboard.c (read_char): Use UNSIGNED_CMP.
19003 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
19004 not to EMACS_INT, to avoid GCC warning.
19006 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
19008 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
19009 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
19010 isn't needed on 32-bit machines.
19012 * buffer.c (Fgenerate_new_buffer_name):
19013 Use EMACS_INT for count, not int.
19014 (advance_to_char_boundary): Return EMACS_INT, not int.
19016 * data.c (Qcompiled_function): Now static.
19018 * window.c (window_body_lines): Now static.
19020 * image.c (gif_load): Rename local to avoid shadowing.
19022 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
19023 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
19024 * alloc.c (make_save_value): Integer argument is now of type
19025 ptrdiff_t, not int.
19026 (mark_object): Use ptrdiff_t, not int.
19027 * lisp.h (pD): New macro.
19028 * print.c (print_object): Use it.
19030 * alloc.c: Use EMACS_INT, not int, to count objects.
19031 (total_conses, total_markers, total_symbols, total_vector_size)
19032 (total_free_conses, total_free_markers, total_free_symbols)
19033 (total_free_floats, total_floats, total_free_intervals)
19034 (total_intervals, total_strings, total_free_strings):
19035 Now EMACS_INT, not int. All uses changed.
19036 (Fgarbage_collect): Compute overall total using a double, so that
19037 integer overflow is less likely to be a problem. Check for overflow
19038 when converting back to an integer.
19039 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
19040 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
19041 These were 'int' variables that could overflow on 64-bit hosts;
19042 they were never used, so remove them instead of repairing them.
19043 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
19044 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
19045 Previously, this ceilinged at INT_MAX, but that doesn't work on
19047 (allocate_pseudovector): Don't use EMACS_INT when int would do.
19049 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
19050 (allocate_vectorlike): Check for ptrdiff_t overflow.
19051 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
19052 when a (possibly-narrower) signed value would do just as well.
19053 We prefer using signed arithmetic, to avoid comparison confusion.
19055 * alloc.c: Catch some string size overflows that we were missing.
19056 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
19057 for convenience in STRING_BYTES_MAX.
19058 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
19059 The definition here is exact; the one in lisp.h was approximate.
19060 (allocate_string_data): Check for string overflow. This catches
19061 some instances we weren't catching before. Also, it catches
19062 size_t overflow on (unusual) hosts where SIZE_MAX <= min
19063 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
19064 and ptrdiff_t and EMACS_INT are both 64 bits.
19066 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
19067 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
19068 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
19070 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
19072 * alloc.c (Fmake_string): Check for out-of-range init.
19074 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
19076 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
19078 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
19080 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
19081 xg_get_default_scrollbar_width.
19083 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
19084 (int_gtk_range_get_value): Move to the scroll bar part of the file.
19085 (style_changed_cb): Call update_theme_scrollbar_width and call
19086 x_set_scroll_bar_default_width and xg_frame_set_char_size for
19087 all frames (Bug#8505).
19088 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
19089 Call gtk_window_set_resizable if HAVE_GTK3.

19538 Fframe_first_window and Fset_frame_selected_window to window.h.
19540 * window.h: Move EXFUNS for Fframe_root_window,
19541 Fframe_first_window and Fset_frame_selected_window here from

19545 (Fframe_root_window, Fframe_selected_window)
19546 (Fset_frame_selected_window): Move to window.c.
19547 (Factive_minibuffer_window): Move to minibuf.c.
19548 (Fother_visible_frames_p): New function.

19564 (Fwindow_minibuffer_p): Move up in code and simplify.
19565 (Fset_frame_selected_window): Move here from frame.c.
19567 (Fselected_window, select_window, Fselect_window): Move up in
19568 code. Minor doc-string fixes.
19570 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
19572 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
19573 Do not assume that spare memory exists; that assumption is valid
19574 only if SYSTEM_MALLOC.
19575 (LARGE_REQUEST): New macro, so that the issue of large requests
19576 is separated from the issue of spare memory.
19578 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
19580 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

19606 New error handlers.
19607 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
19608 Obey Vx_select_enable_clipboard_manager. Catch errors in
19609 x_clipboard_manager_save (Bug#8779).
19610 (Vx_select_enable_clipboard_manager): New variable.
19611 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
19613 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
19615 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
19617 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19619 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
19620 in the current matrix if keep_current_p is non-zero.

19624 * bidi.c (bidi_level_of_next_char): Fix last change.
19626 2011-06-03 Eli Zaretskii <eliz@gnu.org>
19628 Support bidi reordering of text covered by display properties.
19630 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
19631 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
19632 (bidi_cache_search, bidi_cache_iterator_state)
19633 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
19634 (bidi_level_of_next_char, bidi_move_to_visually_next):
19635 Support character positions inside a run of characters covered by a
19637 (bidi_paragraph_init, bidi_resolve_explicit_1)
19638 (bidi_level_of_next_char): Call bidi_fetch_char and
19639 bidi_fetch_char_advance instead of FETCH_CHAR and
19640 FETCH_CHAR_ADVANCE.

19642 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
19644 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
19645 instead of using explicit *_CHAR codes.
19646 (bidi_resolve_explicit, bidi_resolve_weak):
19647 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
19648 bidirectional text is supported only in multibyte buffers.
19649 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
19650 it to initialize the frame_window_p member of struct bidi_it.
19651 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
19652 (bidi_resolve_explicit, bidi_resolve_weak)

19654 bidi_it->nchars is non-positive.
19655 (bidi_level_of_next_char): Don't try to lookup the cache for the
19656 next/previous character if nothing is cached there yet, or if we
19657 were just reseat()'ed to a new position.
19659 * xdisp.c (set_cursor_from_row): Set start and stop points
19660 according to the row's direction when priming the loop that looks
19661 for the glyph on which to display cursor.
19662 (single_display_spec_intangible_p): Function deleted.
19663 (display_prop_intangible_p): Reimplement to call
19664 handle_display_spec instead of single_display_spec_intangible_p.
19665 Accept 3 additional arguments needed by handle_display_spec.
19666 This fixes incorrect cursor motion across display property with complex
19667 values: lists, `(when COND...)' forms, etc.
19668 (single_display_spec_string_p): Support property values that are
19669 lists with the argument STRING its top-level element.
19670 (display_prop_string_p): Fix the condition for processing a
19671 property that is a list to be consistent with handle_display_spec.
19672 (handle_display_spec): New function, refactored from the
19673 last portion of handle_display_prop.
19674 (compute_display_string_pos): Accept additional argument
19675 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
19676 value of a `display' property is a "replacing spec".
19677 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19678 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
19679 the display property, but just return a value indicating whether
19680 the display property will replace the characters it covers.
19681 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
19682 frame_window_p members of struct bidi_it.
19683 (compute_display_string_pos, compute_display_string_end):
19685 (push_it): Accept second argument POSITION, where pop_it should
19686 jump to continue iteration.
19687 (reseat_1): Initialize bidi_it.disp_pos.
19689 * keyboard.c (adjust_point_for_property): Adjust the call to
19690 display_prop_intangible_p to its new signature.
19692 * dispextern.h (struct bidi_it): New member frame_window_p.
19693 (bidi_init_it): Update prototypes.
19694 (display_prop_intangible_p): Update prototype.
19695 (compute_display_string_pos, compute_display_string_end):
19696 Declare prototypes.
19697 (struct bidi_it): New members nchars and disp_pos. ch_len is now
19700 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
19702 Malloc failure behavior now depends on size of allocation.
19703 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
19704 * lisp.h: Change signatures accordingly.
19705 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
19706 All callers changed. (Bug#8762)
19708 * gnutls.c: Use Emacs's memory allocators.
19709 Without this change, the gnutls library would invoke malloc etc.
19710 directly, which causes problems on non-SYNC_INPUT hosts, and which
19711 runs afoul of improving memory_full behavior. (Bug#8761)
19712 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19713 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19714 xfree instead of the default malloc, realloc, free.
19715 (Fgnutls_boot): No need to check for memory allocation failure,
19716 since xmalloc does that for us.
19718 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
19719 * category.c (hash_get_category_set):
19720 * ccl.c (ccl_driver):
19721 * charset.c (Fdefine_charset_internal):
19722 * charset.h (struct charset.hash_index):

19732 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
19733 (Fsxhash, Fgethash, Fputhash, Fmaphash):
19734 * image.c (make_image, search_image_cache, lookup_image)
19735 (xpm_put_color_table_h):
19736 * lisp.h (struct Lisp_Hash_Table):
19737 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
19738 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
19739 for hashes and hash indexes, instead of 'unsigned' and 'int'.
19740 * alloc.c (allocate_vectorlike):
19741 Check for overflow in vector size calculations.
19742 * ccl.c (ccl_driver):
19743 Check for overflow when converting EMACS_INT to int.
19744 * fns.c, image.c: Remove unnecessary static decls that would otherwise
19745 need to be updated by these changes.
19746 * fns.c (make_hash_table, maybe_resize_hash_table):
19747 Check for integer overflow with large hash tables.
19748 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19749 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19750 (SXHASH_REDUCE): New macro.
19751 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19752 Use it instead of discarding useful hash info with large hash values.
19753 (sxhash_float): New function.
19754 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19755 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19756 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19757 Rewrite to use FIXNUM_BITS, as this simplifies things.
19758 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19759 Adjust signatures to match updated version of code.
19760 (consing_since_gc): Now EMACS_INT, since a single hash table can
19761 use more than INT_MAX bytes.
19763 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
19765 Make it possible to build with GCC-4.6+ -O2 -flto.
19767 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
19769 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
19771 * minibuf.c (get_minibuffer, read_minibuf_unwind):
19772 Call minibuffer-inactive-mode.
19774 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
19776 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
19777 Update dependencies.
19779 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19781 * data.c (init_data): Remove code for UTS, this system is not
19784 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19786 Don't force ./temacs to start in terminal mode.
19788 * frame.c (make_initial_frame): Initialize faces in all cases, not
19789 only when CANNOT_DUMP is defined.
19790 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
19792 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19794 * dispnew.c (add_window_display_history): Use const for the string
19795 pointer. Remove declaration, not needed.
19797 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19799 Use 'inline', not 'INLINE'.
19800 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
19801 * alloc.c, fontset.c (INLINE): Remove.
19802 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
19803 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
19804 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
19805 * gmalloc.c (register_heapinfo): Use inline unconditionally.
19806 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
19808 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19810 Make it possible to run ./temacs.
19812 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19813 syms_of_callproc does the same thing. Remove test for
19814 "initialized", do it in the caller.
19815 * emacs.c (main): Avoid calling set_initial_environment when dumping.
19817 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
19819 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
19820 (read_minibuf): Use get_minibuffer.
19821 (syms_of_minibuf): Use DEFSYM.
19822 (Qmetadata): New var.
19823 * data.c (Qbuffer): Don't make it static.
19824 (syms_of_data): Use DEFSYM.
19826 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19828 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
19829 (CCL_CODE_MIN): New macro.
19831 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
19833 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
19835 * eval.c (Qdebug): Now static.
19836 * lisp.h (Qdebug): Remove decl. This reverts a part of the
19837 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
19838 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
19840 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19842 * image.c: Various fixes to ImageMagick code comments.
19843 (Fimagemagick_types): Doc fix.
19845 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
19847 Minor fixes prompted by GCC 4.6.0 warnings.
19849 * xselect.c (converted_selections, conversion_fail_tag): Now static.
19851 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
19852 (x_clipboard_manager_save_all): Move extern decl to ...
19853 * xterm.h: ... here, so that it can be checked for consistency.
19855 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19857 * xselect.c (x_clipboard_manager_save_frame)
19858 (x_clipboard_manager_save_all): New functions.
19859 (Fx_clipboard_manager_save): Lisp function deleted.
19861 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
19862 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
19864 * xterm.h: Update prototype.
19866 2011-05-28 William Xu <william.xwl@gmail.com>
19868 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
19869 exiting (Bug#8239).
19871 2011-05-28 Jim Meyering <meyering@redhat.com>
19873 Avoid a sign-extension bug in crypto_hash_function.
19874 * fns.c (to_uchar): Define.
19875 (crypto_hash_function): Use it to convert some newly-signed
19876 variables to unsigned, to avoid sign-extension bugs. For example,
19877 without this change, (md5 "truc") would evaluate to
19878 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19879 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19880 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19882 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19884 Integer overflow fixes.
19886 * dbusbind.c: Serial number integer overflow fixes.
19887 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19888 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19889 to hold a serial number that is too large for a fixnum.
19890 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19891 Check for serial numbers out of range. Decode any serial number
19892 that was so large that it became a float. (Bug#8722)
19894 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19895 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19896 Use XFASTINT rather than XUINT when numbers are nonnegative.
19897 (xd_append_arg, Fdbus_method_return_internal):
19898 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19899 arguments, check that Lisp number is nonnegative, rather than
19900 silently wrapping negative numbers around. (Bug#8722)
19901 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19904 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19906 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19908 ccl: Add integer overflow checks.
19909 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19910 (IN_INT_RANGE): New macros.
19911 (ccl_driver): Use them to check for integer overflow when
19912 decoding a CCL program. Many of the new checks are whether XINT (x)
19913 fits in int; it doesn't always, on 64-bit hosts. The new version
19914 doesn't catch all possible integer overflows, but it's an
19915 improvement. (Bug#8719)
19917 * alloc.c (make_event_array): Use XINT, not XUINT.
19918 There's no need for unsigned here.
19920 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19921 This follows up to the 2011-05-06 change that substituted uintptr_t
19922 for EMACS_INT. This case wasn't caught back then.
19924 Rework Fformat to avoid integer overflow issues.
19925 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19926 now (part of C89). Include <verify.h>.
19927 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19928 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19929 (Fformat): Avoid the prepass trying to compute sizes; it was only
19930 approximate and thus did not catch overflow reliably. Instead, walk
19931 through the format just once, formatting and computing sizes as we go,
19932 checking for integer overflow at every step, and allocating a larger
19933 buffer as needed. Keep track separately whether the format is
19934 multibyte. Keep only the most-recently calculated precision, rather
19935 than them all. Record whether each argument has been converted to
19936 string. Use EMACS_INT, not int, for byte and char and arg counts.
19937 Support field widths and precisions larger than INT_MAX. Avoid
19938 sprintf's undefined behavior with conversion specifications such as %#d
19939 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19940 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19941 formatting out-of-range floating point numbers with int
19942 formats. (Bug#8668)
19944 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19946 * data.c: Avoid integer truncation in expressions involving floats.
19947 * data.c: Include <intprops.h>.
19948 (arith_driver): When there's an integer overflow in an expression
19949 involving floating point, convert the integers to floating point
19950 so that the resulting value does not suffer from catastrophic
19951 integer truncation. For example, on a 64-bit host (* 4
19952 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19953 Do not rely on undefined behavior after integer overflow.
19955 merge count_size_as_multibyte, parse_str_to_multibyte
19956 * character.c, character.h (count_size_as_multibyte):
19957 Rename from parse_str_to_multibyte; all uses changed.
19958 Check for integer overflow.
19959 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19960 since it's now a duplicate of the other. This is more of
19961 a character than a buffer op, so better that it's in character.c.
19962 * fns.c, print.c: Adjust to above changes.
19964 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19966 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19968 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19970 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19971 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19972 (x_clipboard_manager_save): Now static.
19973 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19975 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19976 (crypto_hash_function): Now static.
19977 Fix pointer signedness problems. Avoid unnecessary initializations.
19979 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19981 * termhooks.h (Vselection_alist): Make it terminal-local.
19983 * terminal.c (create_terminal): Initialize it.
19985 * xselect.c: Support for clipboard managers.
19986 (Vselection_alist): Move to termhooks.h as terminal-local var.
19987 (LOCAL_SELECTION): New macro.
19988 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19989 (symbol_to_x_atom): Remove gratuitous arg.
19990 (x_handle_selection_request, lisp_data_to_selection_data)
19991 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19992 (x_own_selection, x_get_local_selection, x_convert_selection):
19993 New arg, specifying work frame. Use terminal-local Vselection_alist.
19994 (some_frame_on_display): Delete unused function.
19995 (Fx_own_selection_internal, Fx_get_selection_internal)
19996 (Fx_disown_selection_internal, Fx_selection_owner_p)
19997 (Fx_selection_exists_p): New optional frame arg.
19998 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19999 (x_handle_selection_clear): Don't treat other terminals with the
20000 same keyboard specially. Use the terminal-local Vselection_alist.
20001 (x_clear_frame_selections): Use Frun_hook_with_args.
20003 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
20005 * xterm.h: Add support for those atoms.
20007 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
20009 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
20010 (converted_selections, conversion_fail_tag): New global variables.
20011 (x_selection_request_lisp_error): Free the above.
20012 (x_get_local_selection): Remove unnecessary code.
20013 (x_reply_selection_request): Args changed; handle arbitrary array
20014 of converted selections stored in converted_selections.
20015 Separate the XChangeProperty and SelectionNotify steps.
20016 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
20017 (x_convert_selection): New function.
20018 (x_handle_selection_event): Simplify.
20019 (x_get_foreign_selection): Don't ignore incoming requests while
20020 waiting for an answer; this will fail when we implement
20021 SAVE_TARGETS, and seems unnecessary anyway.
20022 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
20023 (Vx_sent_selection_functions): Doc fix.
20025 2011-05-26 Leo Liu <sdl.web@gmail.com>
20027 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
20029 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20031 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
20033 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
20034 for fringe update if it has periodic bitmap.
20035 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
20036 and fringe_bitmap_periodic_p.
20038 * fringe.c (get_fringe_bitmap_data): New function.
20039 (draw_fringe_bitmap_1, update_window_fringes): Use it.
20040 (update_window_fringes): Record periodicity of fringe bitmap in glyph
20041 row. Mark glyph row for fringe update if periodicity changed.
20043 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
20044 for fringe update unless it has periodic bitmap.
20046 2011-05-25 Kenichi Handa <handa@m17n.org>
20048 * xdisp.c (get_next_display_element): Set correct it->face_id for
20049 a static composition.
20051 2011-05-24 Leo Liu <sdl.web@gmail.com>
20054 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
20056 * fns.c (crypto_hash_function, Fsha1): New function.
20057 (Fmd5): Use crypto_hash_function.
20058 (syms_of_fns): Add Ssha1.
20060 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20062 * gnutls.c: Remove unused macros.
20063 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
20064 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
20065 Remove macros that are defined and never used.
20066 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
20068 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20070 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
20071 (Fx_get_selection_internal): Minor cleanup.
20072 (Fx_own_selection_internal): Rename arguments for consistency with
20075 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20077 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
20079 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20081 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
20083 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20085 * dispnew.c (scrolling_window): Don't exclude the case that the
20086 last enabled row in the desired matrix touches the bottom boundary.
20088 2011-05-21 Glenn Morris <rgm@gnu.org>
20090 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
20091 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
20092 and add some more files.
20094 2011-05-20 Eli Zaretskii <eliz@gnu.org>
20096 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
20097 report_file_error introduced by the change from 2011-05-07.
20099 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
20101 * systime.h (Time): Define only if emacs is defined.
20102 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
20103 where the include path doesn't have X11/X.h by default. See
20104 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
20106 2011-05-20 Kenichi Handa <handa@m17n.org>
20108 * composite.c (find_automatic_composition): Fix previous change.
20110 2011-05-20 Glenn Morris <rgm@gnu.org>
20112 * lisp.mk: New file, split from Makefile.in.
20113 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
20114 (shortlisp): Remove.
20115 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
20117 2011-05-19 Glenn Morris <rgm@gnu.org>
20119 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
20120 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
20121 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
20122 (lisp): Set the order to that of loadup.el.
20123 (shortlisp): Make it a copy of $lisp.
20124 (SOME_MACHINE_LISP): Remove.
20125 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
20126 Use just $shortlisp, not $SOME_MACHINE_LISP too.
20128 2011-05-18 Kenichi Handa <handa@m17n.org>
20130 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
20131 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
20132 (find_automatic_composition): Mostly rewrite for efficiency.
20134 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
20136 * makefile.w32-in: Update dependencies.
20138 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
20140 * menu.c: Include limits.h (fixes the MS-Windows build broken by
20141 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
20143 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
20145 Fix some integer overflow issues, such as string length overflow.
20147 * insdel.c (count_size_as_multibyte): Check for string overflow.
20149 * character.c (lisp_string_width): Check for string overflow.
20150 Use EMACS_INT, not int, for string indexes and lengths; in
20151 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
20152 the resulting string length overflows an EMACS_INT; instead,
20153 report a string overflow if no precision given. When checking for
20154 precision exhaustion, use a check that cannot possibly have
20155 integer overflow. (Bug#8675)
20156 * character.h (lisp_string_width): Adjust to new signature.
20158 * alloc.c (string_overflow): New function.
20159 (Fmake_string): Use it. This doesn't change behavior, but saves
20160 a few bytes and will simplify future changes.
20161 * character.c (string_escape_byte8): Likewise.
20162 * lisp.h (string_overflow): New decl.
20164 Fixups, following up to the user-interface timestamp change.
20165 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
20166 for UI timestamps, instead of unsigned long.
20167 * msdos.c (mouse_get_pos): Likewise.
20168 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
20169 * w32gui.h (Time): Define by including "systime.h" rather than by
20170 declaring it ourselves. (Bug#8664)
20172 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
20173 * image.c (clear_image_cache): Likewise.
20175 * term.c (term_mouse_position): Don't assume time_t wraparound.
20177 Be more systematic about user-interface timestamps.
20178 Before, the code sometimes used 'Time', sometimes 'unsigned long',
20179 and sometimes 'EMACS_UINT', to represent these timestamps.
20180 This change causes it to use 'Time' uniformly, as that's what X uses.
20181 This makes the code easier to follow, and makes it easier to catch
20182 integer overflow bugs such as Bug#8664.
20183 * frame.c (Fmouse_position, Fmouse_pixel_position):
20184 Use Time, not unsigned long, for user-interface timestamps.
20185 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
20186 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
20187 * keyboard.h (last_event_timestamp): Likewise.
20188 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
20189 * menu.h (xmenu_show): Likewise.
20190 * term.c (term_mouse_position): Likewise.
20191 * termhooks.h (struct input_event.timestamp): Likewise.
20192 (struct terminal.mouse_position_hook): Likewise.
20193 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
20194 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
20195 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
20196 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
20197 what it was before.
20198 * menu.h, termhooks.h: Include "systime.h", for Time.
20200 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
20201 Don't assume that the difference between two unsigned long values
20202 can fit into an integer. At this point, we know button_down_time
20203 <= event->timestamp, so the difference must be nonnegative, so
20204 there's no need to cast the result if double-click-time is
20205 nonnegative, as it should be; check that it's nonnegative, just in
20206 case. This bug is triggered when events are more than 2**31 ms
20207 apart (about 25 days). (Bug#8664)
20209 * xselect.c (last_event_timestamp): Remove duplicate decl.
20210 (x_own_selection): Remove needless cast to unsigned long.
20212 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
20213 that always fit in int. Use a sentinel instead of a counter, to
20214 avoid a temp and to allay GCC's concerns about possible int overflow.
20215 * frame.h (struct frame): Use int for menu_bar_items_used
20216 instead of EMACS_INT, since it always fits in int.
20218 * menu.c (grow_menu_items): Check for int overflow.
20220 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
20222 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
20223 Before, the code was not consistent. These values cannot exceed
20224 2**31 - 1 so there's no need to make them unsigned.
20225 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
20226 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
20227 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
20229 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
20231 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
20232 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
20233 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
20234 presumably because the widths might not match.
20236 * window.c (size_window): Avoid needless test at loop start.
20238 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
20240 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
20242 2011-05-12 Drew Adams <drew.adams@oracle.com>
20244 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
20246 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20248 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
20249 `width' to `bar_area_x' and `bar_area_width', respectively.
20250 (x_scroll_run): Take account of fringe background extension.
20252 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
20253 Rename local vars `left' and `width' to `bar_area_x' and
20254 `bar_area_width', respectively.
20255 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
20256 background extension.
20258 2011-05-10 Jim Meyering <meyering@redhat.com>
20260 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
20262 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
20264 * image.c (Finit_image_library): Return t for built-in image types,
20265 like pbm and xbm. (Bug#8640)
20267 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
20269 * w32menu.c (set_frame_menubar): Fix submenu allocation.
20271 2011-05-07 Eli Zaretskii <eliz@gnu.org>
20273 * w32console.c (Fset_screen_color): Doc fix.
20274 (Fget_screen_color): New function.
20275 (syms_of_ntterm): Defsubr it.
20277 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
20278 unlink the temporary file if Fcall_process didn't create it in the
20280 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
20281 child process will be redirected to a file specified with `:file'.
20282 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
20283 cue to call_process_cleanup not to close that handle.
20285 2011-05-07 Ben Key <bkey76@gmail.com>
20287 * makefile.w32-in: The bootstrap-temacs rule now makes use of
20288 one of two shell specific rules, either bootstrap-temacs-CMD or
20289 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
20290 to the previous implementation of the bootstrap-temacs rule.
20291 The bootstrap-temacs-CMD rule is similar to the previous
20292 implementation of the bootstrap-temacs rule except that it
20293 makes use of the ESC_CFLAGS variable instead of the CFLAGS
20296 These changes, along with some changes to nt/configure.bat,
20297 nt/gmake.defs, and nt/nmake.defs, are required to extend my
20298 earlier fix to add support for --cflags and --ldflags options
20299 that include quotes so that it works whether make uses cmd or
20302 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
20304 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
20305 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
20307 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
20308 a string. Handle both cases.
20309 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
20310 (Fdbus_register_method): Use Qinvalid_function.
20312 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20314 * makefile.w32-in: Update dependencies.
20315 (LISP_H): Add inttypes.h and stdin.h.
20316 (PROCESS_H): Add unistd.h.
20318 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20320 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20321 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20323 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20325 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20327 * term.c (vfatal): Remove stray call to va_end.
20328 It's not needed and the C Standard doesn't allow it here anyway.
20330 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20331 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20333 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20336 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20338 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20340 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20342 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20344 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20346 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20347 * charset.c (Fdefine_charset_internal): Don't initialize
20348 charset.code_space[15]. The value was garbage, on hosts with
20349 32-bit int (Bug#8600).
20351 * lread.c (read_integer): Be more consistent with string-to-number.
20352 Use string_to_number to do the actual conversion; this avoids
20353 rounding errors and fixes some other screwups. Without this fix,
20354 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20355 (digit_to_number): Move earlier, for benefit of read_integer.
20356 Return -1 if the digit is out of range for the base, -2 if it is
20357 not a digit in any supported base. (Bug#8602)
20359 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20361 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20362 to match comment at start of function. This also removes a
20363 GCC warning about overflow in a 32+64-bit port.
20365 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20367 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20368 Reported by Stefan Monnier in
20369 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20370 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20371 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20373 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20374 (EMACS_UINTPTR): Likewise, with uintptr_t.
20376 * lisp.h: Prefer 64-bit EMACS_INT if available.
20377 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20378 on 32-bit hosts that have 64-bit int, so that they can access
20380 However, temporarily disable this change unless the temporary
20381 symbol WIDE_EMACS_INT is defined.
20383 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20385 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20386 This removes an assumption that EMACS_INT and long are the same
20387 width as pointers. The assumption is true for Emacs porting targets
20388 now, but we want to make other targets possible.
20389 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20390 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20391 In the rest of the code, change types of integers that hold casted
20392 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20393 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20394 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20395 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20396 No need to cast type when ORing.
20397 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20398 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20399 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20400 assume EMACS_INT is the same width as char *.
20401 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20402 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20403 Remove no-longer-needed casts.
20404 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20405 (xg_tool_bar_help_callback, xg_make_tool_item):
20406 Use EMACS_INTPTR to hold an integer
20407 that will be cast to void *; this can avoid a GCC warning
20408 if EMACS_INT is not the same width as void *.
20409 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20410 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20411 (current_message_1, set_message_1):
20412 Use a local to convert to proper width without a cast.
20413 * xmenu.c (dialog_selection_callback): Likewise.
20415 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20416 Also, don't assume VALBITS / RAND_BITS is less than 5,
20417 and don't rely on undefined behavior when shifting a 1 left into
20419 * lisp.h (get_random): Change signature to match.
20421 * lread.c (hash_string): Use size_t, not int, for hash computation.
20422 Normally we prefer signed values; but hashing is special, because
20423 it's better to use unsigned division on hash table sizes so that
20424 the remainder is nonnegative. Also, size_t is the natural width
20425 for hashing into memory. The previous code used 'int', which doesn't
20426 retain enough info to hash well into very large tables.
20427 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20429 * dbusbind.c: Don't possibly lose pointer info when converting.
20430 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20431 Use XPNTR rather than XHASH, so that the high-order bits of
20432 the pointer aren't lost when converting through void *.
20434 * eval.c (Fautoload): Don't double-shift a pointer.
20436 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
20438 2011-05-06 Juanma Barranquero <lekktu@gmail.com>

20470 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
20471 Remove unused parameter `fildes'.
20472 * process.c (read_process_output, send_process): Don't pass it.
20474 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20476 Fix previous change: the library cache is defined in w32.c.
20477 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
20478 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

20513 (w32_delayed_load): Move from image.c. When loading a library, record
20514 its filename in the :loaded-from property of the library id.
20515 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
20516 Initialize and staticpro them.

20519 * process.c: Include lisp.h before w32.h, not after.
20520 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20521 instead of gnutls_record_check_pending.
20523 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
20525 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20527 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
20528 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
20531 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
20533 * xterm.c (x_set_frame_alpha): Do not set property on anything
20534 else than FRAME_X_OUTER_WINDOW (Bug#8608).

20538 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
20540 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20542 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

20556 * sysdep.c (wait_for_termination_1): Make static.
20557 (wait_for_termination, interruptible_wait_for_termination):
20558 Move after wait_for_termination_1.

20563 which is like wait_for_termination, but allows keyboard
20566 * callproc.c (Fcall_process): Add (:file "file") as an option for
20568 (Fcall_process_region): Ditto.
20570 2011-04-30 Eli Zaretskii <eliz@gnu.org>
20572 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
20573 rather than `XVECTOR (FOO)->size'.
20575 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20576 inttypes.h, as a gnulib replacement is used if it not available in
20579 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20581 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
20582 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
20583 of MOST_POSITIVE_FIXNUM. (Bug#8528)
20585 * coding.c (coding_alloc_by_realloc): Error out if destination
20586 will grow beyond MOST_POSITIVE_FIXNUM.
20587 (decode_coding_emacs_mule): Abort if there isn't enough place in
20588 charbuf for the composition carryover bytes. Reserve an extra
20589 space for up to 2 characters produced in a loop.

20591 charbuf for the composition carryover bytes.
20593 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20595 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
20596 aborting when %lld or %lll format is passed.
20597 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
20598 %llo or %llx format is passed. (Bug#8545)
20600 * window.c (window_scroll_line_based): Use a marker instead of
20601 simple variables to record original value of point. (Bug#7952)
20603 * doprnt.c (doprnt): Fix the case where a multibyte sequence
20604 produced by %s or %c overflows available buffer space. (Bug#8545)
20606 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20608 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

20620 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
20621 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
20623 2011-04-28 Eli Zaretskii <eliz@gnu.org>
20625 * doprnt.c (doprnt): Don't return value smaller than the buffer
20626 size if the message was truncated. (Bug#8545).
20628 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20630 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

20637 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20639 * makefile.w32-in: Update dependencies.
20641 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20643 Improve `doprnt' and its usage. (Bug#8545)
20644 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20645 `format_end'. Remove support for %l as a conversion specifier.
20646 Don't use xrealloc. Improve diagnostics when the %l size modifier
20647 is used. Update the commentary.
20649 * eval.c (verror): Simplify calculation of size_t.
20651 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20654 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20656 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20659 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20661 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20662 This makes this file independent of the recent pseudovector change.
20664 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20666 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20668 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20669 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20670 Remove unused local.
20671 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20673 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20674 GCC 4.6.0 optimizes based on type-based alias analysis.
20675 For example, if b is of type struct buffer * and v of type struct
20676 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20677 != &v->size, and therefore "v->size = 1; b->size = 2; return
20678 v->size;" must therefore return 1. This assumption is incorrect
20679 for Emacs, since it type-puns struct Lisp_Vector * with many other
20680 types. To fix this problem, this patch adds a new type struct
20681 vectorlike_header that documents the constraints on layout of vectors
20682 and pseudovectors, and helps optimizing compilers not get fooled
20683 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20684 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20685 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20687 (XSETPVECTYPE): Rewrite in terms of new macro.
20688 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20689 This is a bit clearer, and further avoids the possibility of
20690 undesirable aliasing.
20691 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20692 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20693 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20694 since Lisp_Subr is a special case (no "next" field).
20695 (ASIZE): Now uses header.size rather than size.
20696 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20697 to avoid the hassle of writing XVECTOR (foo)->header.size.
20698 (struct vectorlike_header): New type.
20699 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20700 object, to help avoid aliasing.
20701 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20702 (SUBRP): Likewise, since Lisp_Subr is a special case.
20703 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20704 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20705 (struct Lisp_Hash_Table): Combine first two members into a single
20706 struct vectorlike_header member. All uses of "size" and "next" members
20707 changed to be "header.size" and "header.next".
20708 * buffer.h (struct buffer): Likewise.
20709 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20710 * frame.h (struct frame): Likewise.
20711 * process.h (struct Lisp_Process): Likewise.
20712 * termhooks.h (struct terminal): Likewise.
20713 * window.c (struct save_window_data, struct saved_window): Likewise.
20714 * window.h (struct window): Likewise.
20715 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20716 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20717 * buffer.c (init_buffer_once): Likewise.
20718 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20720 * process.c (Fformat_network_address): Use local var for size,
20723 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20725 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20726 * data.c (atof): Remove decl; no longer used or needed.
20727 (digit_to_number): Move to lread.c.
20728 (Fstring_to_number): Use new string_to_number function, to be
20729 consistent with how the Lisp reader treats infinities and NaNs.
20730 Do not assume that floating-point numbers represent EMACS_INT
20731 without losing information; this is not true on most 64-bit hosts.
20732 Avoid double-rounding errors, by insisting on integers when
20733 parsing non-base-10 numbers, as the documentation specifies.
20734 * lisp.h (string_to_number): New decl, replacing ...
20735 (isfloat_string): Remove.
20736 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20737 (read1): Do not accept +. and -. as integers; this
20738 appears to have been a coding error. Similarly, do not accept
20739 strings like +-1e0 as floating point numbers. Do not report
20740 overflow for integer overflows unless the base is not 10 which
20741 means we have no simple and reliable way to continue.
20742 Break out the floating-point parsing into a new
20743 function string_to_number, so that Fstring_to_number parses
20744 floating point numbers consistently with the Lisp reader.
20745 (digit_to_number): Move here from data.c. Make it static inline.
20746 (E_CHAR, EXP_INT): Remove, replacing with ...
20747 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20748 (string_to_number): New function, replacing isfloat_string.
20749 This function checks for valid syntax and produces the resulting
20750 Lisp float number too. Rework it so that string-to-number
20751 no longer mishandles examples like "1.0e+". Use strtoumax,
20752 so that overflow for non-base-10 numbers is reported only when
20753 there's no portable and simple way to convert to floating point.
20755 * textprop.c (set_text_properties_1): Rewrite for clarity,
20756 and to avoid GCC warning about integer overflow.
20758 * intervals.h (struct interval): Use EMACS_INT for members
20759 where EMACS_UINT might cause problems. See
20760 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20761 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20762 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20764 (offset_intervals): Tell GCC not to worry about length overflow
20765 when negating a negative length.
20767 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20768 (overrun_check_free): Likewise.
20770 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20771 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20774 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20775 (gnutls_make_error): Rename local to avoid shadowing.
20776 (gnutls_emacs_global_deinit): ifdef out; not used.
20777 (Fgnutls_boot): Use const for pointer to readonly storage.
20778 Comment out unused local. Fix pointer signedness problems.
20780 * lread.c (openp): Don't stuff size_t into an 'int'.
20781 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20782 about possible signed overflow.
20784 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20785 (GDK_KEY_g): Don't define if already defined.
20786 (xg_prepare_tooltip): Avoid pointer signedness problem.
20787 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20789 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20790 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20792 * xfns.c (Fx_window_property): Simplify a bit,
20793 to make a bit faster and to avoid GCC 4.6.0 warning.
20794 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20796 * fns.c (internal_equal): Don't assume size_t fits in int.
20798 * alloc.c (compact_small_strings): Tighten assertion a little.
20800 Replace pEd with more-general pI, and fix some printf arg casts.
20801 * lisp.h (pI): New macro, generalizing old pEd macro to other
20802 conversion specifiers. For example, use "...%"pI"d..." rather
20803 than "...%"pEd"...".
20804 (pEd): Remove. All uses replaced with similar uses of pI.
20805 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20806 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20807 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20808 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20809 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20810 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20811 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20813 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20814 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20815 * print.c (safe_debug_print, print_object): Likewise.
20816 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20818 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20819 avoiding the 0 flag, which is not portable.
20820 * process.c (Fmake_network_process): Use pI to avoid cast.
20821 * region-cache.c (pp_cache): Likewise.
20822 * xdisp.c (decode_mode_spec): Likewise.
20823 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
20824 behavior on 64-bit hosts with printf arg.

20826 (x_stop_queuing_selection_requests): Likewise.
20827 (x_get_window_property): Don't truncate byte count to an 'int'
20830 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20831 here, since it parses constructs like leading '-' and spaces,
20832 which are not wanted; and it overflows with large numbers.
20833 Instead, simply match F[0-9]+, which is what is wanted anyway.
20835 * alloc.c: Remove unportable assumptions about struct layout.
20836 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20837 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20838 (allocate_vectorlike, make_pure_vector): Use the new macros,
20839 plus offsetof, to remove unportable assumptions about struct layout.
20840 These assumptions hold on all porting targets that I know of, but
20841 they are not guaranteed, they're easy to remove, and removing them
20842 makes further changes easier.
20844 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20845 This doesn't fix a bug but makes the code clearer.
20846 (string_overrun_cookie): Now const. Use initializers that
20847 don't formally overflow signed char, to avoid warnings.
20848 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20849 can cause Emacs to crash when string overrun checking is enabled.
20850 (allocate_buffer): Don't assume sizeof (struct buffer) is a
20851 multiple of sizeof (EMACS_INT); it need not be, if
20852 alignof(EMACS_INT) < sizeof (EMACS_INT).
20853 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
20855 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

20882 2011-04-25 Eli Zaretskii <eliz@gnu.org>
20884 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
20885 "cast to pointer from integer of different size".
20887 Improve doprnt and its use in verror. (Bug#8545)
20888 * doprnt.c (doprnt): Document the set of format control sequences
20889 supported by the function. Use SAFE_ALLOCA instead of always
20892 * eval.c (verror): Don't limit the buffer size at size_max-1, that
20893 is one byte too soon. Don't use xrealloc; instead xfree and
20896 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
20898 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

20904 parameters of `gnutls-boot' and documented those parameters in the
20905 docstring. Start callback support.
20906 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
20907 unless a fatal error occurred. Call gnutls_alert_send_appropriate

21011 codepoint of an invalid character, to avoid displaying a bogus
21014 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
21015 `error', not SYMBOL_NAME itself.
21017 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
21018 character arguments to `error'.
21020 * charset.c (check_iso_charset_parameter): Fix incorrect argument
21021 to `error' in error message about FINAL_CHAR argument. Make sure
21022 FINAL_CHAR is a character, and use %c when it is passed as
21023 argument to `error'.
21025 2011-04-23 Eli Zaretskii <eliz@gnu.org>
21027 * s/ms-w32.h (localtime): Redirect to sys_localtime.
21029 * w32.c: Include <time.h>.

21093 * dispextern.h (struct redisplay_interface): Rename param
21094 to avoid shadowing.
21095 * termhooks.h (struct terminal): Likewise.

21212 * nsfont.m: Fixed bugs in ns_get_family and
21213 ns_descriptor_to_entity that were caused by using free to
21214 deallocate memory blocks that were allocated by xmalloc (via
21215 xstrdup). This caused Emacs to crash when compiled with
21216 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
21217 --enable-checking=xmallocoverrun). xfree is now used to
21218 deallocate these memory blocks.

21233 Emacs source code has been audited now.
21234 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
21235 (emacs_read, emacs_write): Use it.
21236 * process.c (send_process): Adjust to the new signatures of
21237 emacs_write and emacs_gnutls_write. Do not attempt to store
21238 a byte offset into an 'int'; it might overflow.

21701 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21702 (overrun_check_free): Protoize.
21704 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21706 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21707 since callers should never pass a negative size.
21708 Change the signature to match that of plain 'read' and 'write'; see
21709 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21710 * lisp.h: Update prototypes of emacs_write and emacs_read.
21712 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21714 * xdisp.c (redisplay_window): Don't try to determine the character
21715 position of the scroll margin if the window start point w->startp
21716 is outside the buffer's accessible region. (Bug#8468)
21718 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21720 Fix write-region and its subroutines for buffers > 2GB.
21721 * fileio.c (a_write, e_write): Modify declaration of arguments and
21722 local variables to support buffers larger than 2GB.
21723 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21725 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21726 argument, local variables, and return value.
21728 * lisp.h: Update prototypes of emacs_write and emacs_read.
21730 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21732 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21734 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21736 Fix more problems found by GCC 4.6.0's static checks.
21738 * xdisp.c (vmessage): Use a better test for character truncation.
21740 * charset.c (load_charset_map): <, not <=, for optimization,
21741 and to avoid potential problems with integer overflow.
21742 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21743 * casetab.c (set_identity, shuffle): Likewise.
21744 * editfns.c (Fformat): Likewise.
21745 * syntax.c (skip_chars): Likewise.
21747 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21748 This also lets GCC 4.6.0 generate slightly better loop code.
21750 * callint.c (Fcall_interactively): <, not <=, for optimization.
21751 (Fcall_interactively): Count the number of arguments produced,
21752 not the number of arguments given. This is simpler and lets GCC
21753 4.6.0 generate slightly better code.
21755 * ftfont.c: Distingish more carefully between FcChar8 and char.
21756 The previous code passed unsigned char * to a functions like
21757 strlen and xstrcasecmp that expect char *, which does not
21758 conform to the C standard.
21759 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21760 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21761 char * when the C standard requires it.
21763 * keyboard.c (read_char): Remove unused var.
21765 * eval.c: Port to Windows vsnprintf (Bug#8435).
21766 Include <limits.h>.
21767 (SIZE_MAX): Define if the headers do not.
21768 (verror): Do not give up if vsnprintf returns a negative count.
21769 Instead, grow the buffer. This ports to Windows vsnprintf, which
21770 does not conform to C99. Problem reported by Eli Zaretskii.
21771 Also, simplify the allocation scheme, by avoiding the need for
21772 calling realloc, and removing the ALLOCATED variable.
21774 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21776 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21777 But keep the doprint source code for now, as we might revamp it
21778 and use it again (Bug#8435).
21779 * lisp.h (doprnt): Remove.
21780 * Makefile.in (base_obj): Remove doprnt.o.
21781 * deps.mk (doprnt.o): Remove.
21783 error: Print 32- and 64-bit integers portably (Bug#8435).
21784 Without this change, on typical 64-bit hosts error ("...%d...", N)
21785 was used to print both 32- and 64-bit integers N, which relied on
21786 undefined behavior.
21787 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21788 * lisp.h (error, verror): Mark as printf-like functions.
21789 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21790 Report overflow in size calculations when allocating printf buffer.
21791 Do not truncate output string at its first null byte.
21792 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21793 Truncate the output at a character boundary, since vsnprintf does not
21795 * charset.c (check_iso_charset_parameter): Convert internal
21796 character to string before calling 'error', since %c now has the
21798 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21799 overflow when computing char to be passed to 'error'. Do not
21800 pass Lisp_Object to 'error'; pass the integer instead.
21801 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21802 formatted with plain %d.
21804 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21806 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
21808 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
21810 * xterm.c (x_catch_errors): Remove duplicate declaration.
21812 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
21814 * xdisp.c, lisp.h (message_nolog): Remove; unused.
21816 2011-04-10 Jim Meyering <meyering@redhat.com>
21818 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
21819 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
21820 return ssize_t not "int", and use size_t as the buffer length.
21821 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
21822 * gnutls.h: Update declarations.
21823 * process.c (read_process_output): Use ssize_t, to match.
21824 (send_process): Likewise.
21826 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21828 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
21830 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21832 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
21833 Use unsigned char, to match FcChar8 type definition.
21835 * xterm.c (handle_one_xevent):
21836 * xmenu.c (create_and_show_popup_menu):
21837 * xselect.c (x_decline_selection_request)
21838 (x_reply_selection_request): Avoid type-punned deref of X events.
21840 2011-04-09 Eli Zaretskii <eliz@gnu.org>
21842 Fix some uses of `int' instead of EMACS_INT.
21843 * search.c (string_match_1, fast_string_match)
21844 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
21845 (scan_buffer, find_next_newline_no_quit)
21846 (find_before_next_newline, search_command, Freplace_match)
21847 (Fmatch_data): Make some `int' variables be EMACS_INT.
21849 * xdisp.c (display_count_lines): 3rd argument and return value now
21850 EMACS_INT. All callers changed.
21851 (pint2hrstr): Last argument is now EMACS_INT.
21853 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
21854 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
21855 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
21856 (decode_coding_utf_16, decode_coding_emacs_mule)
21857 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
21858 (decode_coding_ccl, decode_coding_charset)
21859 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
21860 (decode_coding_iso_2022, decode_coding_emacs_mule)
21861 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
21862 <char_offset, last_offset>: Declare EMACS_INT.
21863 (encode_coding_utf_8, encode_coding_utf_16)
21864 (encode_coding_emacs_mule, encode_invocation_designation)
21865 (encode_designation_at_bol, encode_coding_iso_2022)
21866 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
21867 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
21869 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
21870 (encode_invocation_designation): Last argument P_NCHARS is now
21872 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
21873 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
21875 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
21878 * ccl.c (Fccl_execute_on_string): Declare some variables
21881 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
21883 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
21885 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
21887 * process.c (Fformat_network_address): Doc fix.
21889 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
21891 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
21893 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
21895 * keyboard.c (read_char): Call Lisp function help-form-show,
21896 instead of using internal_with_output_to_temp_buffer.
21897 (Qhelp_form_show): New var.
21898 (syms_of_keyboard): Use DEFSYM macro.
21900 * print.c (internal_with_output_to_temp_buffer): Function deleted.
21902 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
21904 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
21906 * process.c (Flist_processes): Remove to Lisp.
21907 (list_processes_1): Delete.

21911 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
21913 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
21915 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
21917 Fix more problems found by GCC 4.6.0's static checks.

21921 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
21923 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
21925 * xdisp.c (vmessage): Mark as a printf-like function.
21927 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
21929 * sound.c (sound_warning): Don't crash if arg contains a printf format.
21931 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
21932 printf-like functions.
21933 (tiff_load): Add casts to remove these marks before passing them
21934 to system-supplied API.
21936 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21938 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21939 This avoids several warnings with gcc -Wstrict-overflow.
21940 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21941 directly, rather than having caller test rule sign. This avoids
21942 some unnecessary tests.
21943 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21944 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21945 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21947 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21948 (xfont_open): Avoid unnecessary tests.
21950 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21952 * composite.h, composite.c (composition_gstring_put_cache):
21953 Use EMACS_INT, not int, for length.

21956 breaking out part of COMPOSITION_DECODE_RULE.
21957 (COMPOSITION_DECODE_RULE): Use it.

21959 by using the new macro.
21961 * textprop.c (set_text_properties_1): Change while to do-while,
21962 since the condition is always true at first.
21964 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21965 (interval_deletion_adjustment): Return unsigned value.
21968 * process.c (list_processes_1, create_pty, read_process_output):

21980 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
21981 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
21982 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
21984 * print.c (print_error_message): Avoid int overflow.
21986 * font.c (font_list_entities): Redo for clarity,
21987 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21989 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21990 (font_score): Avoid potential overflow in diff calculation.
21992 * fns.c (substring_both): Remove var that is set but not used.
21993 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21995 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21997 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21998 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21999 can always succeed if overflow has undefined behavior.
22001 * search.c (boyer_moore, wordify): Remove vars set but not used.
22002 (wordify): Omit three unnecessary tests.
22004 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
22005 All callers changed. This avoids the need for an unused var.
22007 * casefiddle.c (casify_region): Remove var that is set but not used.
22009 * dired.c (file_name_completion): Remove var that is set but not used.
22011 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
22013 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
22014 (Finsert_file_contents): Remove unnecessary code checking fd.
22016 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
22017 Check for integer overflow on size calculations.
22019 * buffer.c (Fprevious_overlay_change): Remove var that is set
22022 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
22023 Remove vars that are set but not used.
22024 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
22025 (timer_check_2): Mark vars as initialized.
22027 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
22029 * image.c (lookup_image): Remove var that is set but not used.
22030 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
22032 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
22033 that are set but not used.
22035 * xfns.c (make_invisible_cursor): Don't return garbage
22036 if XCreateBitmapFromData fails (Bug#8410).
22038 * xselect.c (x_get_local_selection, x_handle_property_notify):
22039 Remove vars that are set but not used.
22041 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

22051 (map_tty_color) [!defined MSDOS]: Likewise.
22053 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
22055 * coding.c: Remove vars that are set but not used.
22056 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
22057 All callers changed.
22058 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
22059 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
22060 (decode_coding_charset): Remove vars that are set but not used.
22062 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
22063 that is set but not used.
22065 * print.c (print_object): Remove var that is set but not used.
22067 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
22068 The gnulib version avoids calling malloc in the usual case,
22069 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
22070 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
22071 * filelock.c (current_lock_owner): Likewise.
22072 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

22075 (emacs_readlink): New function.
22076 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
22077 ../lib/careadlinkat.h.
22079 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
22081 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
22082 first non-nil return value).

22086 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
22087 if not defined (Bug#8403).

22096 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
22097 and thereabouts. All callers changed.
22098 (get_per_char_metric): Remove parameter `f', unused since
22099 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

22103 do not dereference NULL upon failed strdup
22104 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
22105 (ns_get_family): Likewise.
22107 2011-04-02 Juanma Barranquero <lekktu@gmail.com>

22157 but without exporting it to Lisp.
22159 * doc.c (Fdocumentation, store_function_docstring):
22160 * data.c (Finteractive_form): Handle closures.
22162 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
22165 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
22167 (exec_byte_code): New function extracted from Fbyte_code to handle new
22168 calling convention for byte-code-functions. Add new byte-codes.
22170 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
22172 * alloc.c (Fmake_symbol): Init new `declared_special' field.
22174 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22176 * xdisp.c (redisplay_internal): Fix prototype.
22178 2011-03-31 Eli Zaretskii <eliz@gnu.org>
22180 * xdisp.c (SCROLL_LIMIT): New macro.
22181 (try_scrolling): Use it when setting scroll_limit.
22182 Limit scrolling to 100 screen lines.
22183 (redisplay_window): Even when falling back on "recentering",
22184 position point in the window according to scroll-conservatively,
22185 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
22187 (try_scrolling): When point is above the window, allow searching
22188 as far as scroll_max, or one screenful, to compute vertical
22189 distance from PT to the scroll margin position. This prevents
22190 try_scrolling from unnecessarily failing when
22191 scroll-conservatively is set to a value slightly larger than the
22192 window height. Clean up the case of PT below the margin at bottom
22193 of window: scroll_max can no longer be INT_MAX. When aggressive
22194 scrolling is in use, don't let point enter the opposite scroll
22195 margin as result of the scroll.
22196 (syms_of_xdisp) <scroll-conservatively>: Document the
22197 threshold of 100 lines for never-recentering scrolling.
22199 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22201 * dispextern.h (move_it_by_lines):
22202 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
22203 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
22204 (message_log_check_duplicate): Remove parameters `prev_bol' and
22205 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22206 (redisplay_internal): Remove parameter `preserve_echo_area',
22207 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
22209 * indent.c (Fvertical_motion):
22210 * window.c (window_scroll_pixel_based, Frecenter):
22211 Don't pass `need_y_p' to `move_it_by_lines'.
22213 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
22215 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
22216 steal a few bits to be more compact.
22217 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
22218 Remove unneeded casts.
22220 * bytecode.c (Fbyte_code): CAR and CDR can GC.
22222 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
22224 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
22225 binding" message (bug#7967).
22227 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
22229 Fix more problems found by GCC 4.6.0's static checks.
22231 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
22232 Remove unused local var.
22234 * editfns.c (Fmessage_box): Remove unused local var.
22236 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
22237 (note_mode_line_or_margin_highlight, note_mouse_highlight):
22238 Omit unused local vars.
22239 * window.c (shrink_windows): Omit unused local var.
22240 * menu.c (digest_single_submenu): Omit unused local var.
22241 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
22242 Omit unused local var.
22244 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
22245 Don't assume string length fits in int.
22246 (keyremap_step, read_key_sequence): Use size_t for sizes.
22247 (read_key_sequence): Don't check last_real_key_start redundantly.
22249 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
22250 instead of alloca (Bug#8344).
22252 * eval.c (Fbacktrace): Don't assume nargs fits in int.
22253 (Fbacktrace_frame): Don't assume nframes fits in int.
22255 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
22257 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
22260 * term.c (produce_glyphless_glyph): Remove unnecessary test.
22262 * cm.c (calccost): Turn while-do into do-while, for clarity.
22264 * keyboard.c (syms_of_keyboard): Use the same style as later
22265 in this function when indexing through an array. This also
22266 works around GCC bug 48267.
22268 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
22270 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
22272 * chartab.c (sub_char_table_ref_and_range): Redo for slight
22273 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
22275 * keyboard.c, keyboard.h (num_input_events): Now size_t.
22276 This avoids undefined behavior on integer overflow, and is a bit
22277 more convenient anyway since it is compared to a size_t variable.
22279 Variadic C functions now count arguments with size_t, not int.
22280 This avoids an unnecessary limitation on 64-bit machines, which
22281 caused (substring ...) to crash on large vectors (Bug#8344).
22282 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
22283 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
22284 All variadic functions and their callers changed accordingly.
22285 (struct gcpro.nvars): Now size_t, not int. All uses changed.

22287 * editfns.c (general_insert_function): Likewise.
22288 * eval.c (struct backtrace.nargs, interactive_p)
22289 (internal_condition_case_n, run_hook_with_args, apply_lambda)
22290 (funcall_lambda, mark_backtrace): Likewise.
22291 * fns.c (concat): Likewise.
22292 * frame.c (x_set_frame_parameters): Likewise.
22293 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
22294 0 if not found, not -1. All callers changed.
22296 * alloc.c (garbage_collect): Don't assume stack size fits in int.
22297 (stack_copy_size): Now size_t, not int.
22298 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
22300 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
22302 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
22303 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
22304 All callers changed.
22306 * lisp.h (multibyte_char_to_unibyte):
22307 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
22308 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
22309 * character.h (CHAR_TO_BYTE8):
22310 * cmds.c (internal_self_insert):
22311 * editfns.c (general_insert_function):
22312 * keymap.c (push_key_description):
22313 * search.c (Freplace_match):
22314 * xdisp.c (message_dolog, set_message_1): All callers changed.
22316 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
22318 * keyboard.c (safe_run_hook_funcall): New function.
22319 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
22320 don't set the hook to nil, but remove the offending function instead.
22321 (Qcommand_hook_internal): Remove, unused.
22322 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
22323 Vcommand_hook_internal.
22325 * eval.c (enum run_hooks_condition): Remove.
22326 (funcall_nil, funcall_not): New functions.
22327 (run_hook_with_args): Call each function through a `funcall' argument.
22328 Remove `cond' argument, now redundant.
22329 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
22330 (Frun_hook_with_args_until_failure): Adjust accordingly.
22331 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
22333 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
22335 * dispextern.h (string_buffer_position): Remove declaration.
22337 * print.c (strout): Remove parameter `multibyte', unused since
22338 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
22340 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
22341 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
22342 All callers changed.
22344 * w32.c (_wsa_errlist): Use braces for struct initializers.
22346 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
22347 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
22348 All callers changed.
22349 (string_buffer_position): Likewise. Also, make static (it's never
22350 used outside xdisp.c).
22351 (cursor_row_p): Remove parameter `w', unused since
22352 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

22354 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
22355 All callers changed.
22357 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
22359 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

22364 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
22365 (ns_update_auto_hide_menu_bar): New functions.
22366 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

22370 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
22372 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
22374 * nsmenu.m (runDialogAt): Remove argument to timer_check.
22376 2011-03-27 Glenn Morris <rgm@gnu.org>
22378 * syssignal.h: Replace RETSIGTYPE with void.
22379 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
22380 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
22381 Replace SIGTYPE with void everywhere.
22382 * s/usg5-4-common.h (SIGTYPE): Remove definition.

22385 2011-03-26 Eli Zaretskii <eliz@gnu.org>
22387 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
22388 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
22390 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
22392 * w32.c (read_unc_volume): Use parameter `henum', instead of
22393 global variable `wget_enum_handle'.
22395 * keymap.c (describe_vector): Remove parameters `indices' and
22396 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

22399 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
22401 * keyboard.c (timer_check): Remove parameter `do_it_now',
22402 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
22403 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
22404 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
22406 * keyboard.c (read_char):
22407 * w32menu.c (w32_menu_display_help):
22408 * xmenu.c (show_help_event, menu_help_callback):
22409 Adjust calls to `show_help_echo'.
22411 * gtkutil.c (xg_maybe_add_timer):
22412 * keyboard.c (readable_events):
22413 * process.c (wait_reading_process_output):
22414 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
22416 * insdel.c (adjust_markers_gap_motion):
22417 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
22418 (gap_left, gap_right): Don't call it.
22420 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
22422 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
22423 incurred during fontification.

22464 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
22466 * w32term.c (x_set_glyph_string_clipping):
22467 Don't pass uninitialized region to CombineRgn.
22469 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
22471 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
22472 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
22473 (Fx_close_connection): Remove unused variable `i'.
22475 * w32font.c (w32font_draw): Return number of glyphs.

22489 (uniscribe_font_driver): Add missing initializers.
22491 2011-03-23 Julien Danjou <julien@danjou.info>
22493 * term.c (Fsuspend_tty, Fresume_tty):
22494 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
22495 * window.c (temp_output_buffer_show):
22496 * insdel.c (signal_before_change):
22497 * frame.c (Fhandle_switch_frame):

22500 * editfns.c (save_excursion_restore):
22501 * cmds.c (internal_self_insert):
22502 * callint.c (Fcall_interactively):
22503 * buffer.c (Fkill_all_local_variables):
22504 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22506 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22507 unconditionally since it does the check itself.
22509 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22511 Fix more problems found by GCC 4.5.2's static checks.
22513 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22514 the first time through the loop, since we know p0 < p1 then.
22515 This also avoids a gcc -Wstrict-overflow warning.
22517 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22518 leading to a memory leak, possible in functions like
22519 load_charset_map_from_file that can allocate an unbounded number
22520 of objects (Bug#8318).
22522 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22523 that could (at least in theory) be that large.
22525 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22526 This is less likely to overflow, and avoids undefined behavior if
22527 overflow does occur. All callers changed. Use strtoul to scan
22528 for the unsigned long integer.
22529 (pint2hrstr): Simplify and tune code slightly.
22530 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
22532 * scroll.c (do_scrolling): Work around GCC bug 48228.
22533 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
22535 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
22536 This also avoids a warning with gcc -Wstrict-overflow.
22537 (validate_x_resource_name): Simplify count usage.
22538 This also avoids a warning with gcc -Wstrict-overflow.
22540 * fileio.c (Fcopy_file): Report error if fchown or fchmod
22543 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
22545 * process.c (Fmake_network_process): Use socklen_t, not int,
22546 where POSIX says socklen_t is required in portable programs.
22547 This fixes a porting bug on hosts like 64-bit HP-UX, where
22548 socklen_t is wider than int (Bug#8277).
22549 (Fmake_network_process, server_accept_connection):
22550 (wait_reading_process_output, read_process_output):
22553 * process.c: Rename or move locals to avoid shadowing.
22554 (list_processes_1, Fmake_network_process):
22555 (read_process_output_error_handler, exec_sentinel_error_handler):
22556 Rename or move locals.
22557 (Fmake_network_process): Define label "retry_connect" only if needed.
22558 (Fnetwork_interface_info): Fix pointer signedness.
22559 (process_send_signal): Add cast to avoid pointer signedness problem.
22560 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
22561 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
22563 Make tparam.h and terminfo.c consistent.
22564 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22565 Include tparam.h instead, since it declares them.
22566 * cm.h (PC): Remove extern decl; tparam.h now does this.
22567 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22568 * terminfo.c: Include tparam.h, to check interfaces.
22569 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22570 (tparam): Adjust signature to match interface in tparam.h;
22571 this removes some undefined behavior. Check that outstring and len
22572 are zero, which they always are with Emacs.
22573 * tparam.h (PC, BC, UP): New extern decls.
22575 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22576 (xftfont_open): Rename locals to avoid shadowing.
22578 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
22579 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
22580 (OTF_TAG_SYM): Omit macro if not needed.
22581 (ftfont_list): Remove unused local.
22582 (get_adstyle_property, ftfont_pattern_entity):
22583 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
22584 Rename locals to avoid shadowing.
22586 * xfont.c (xfont_list_family): Mark var as initialized.
22588 * xml.c (make_dom): Now static.
22590 * composite.c (composition_compute_stop_pos): Rename local to

22627 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22629 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22630 This should get cleaned up, so that child_setup has the
22631 same signature on all platforms.

22795 (Fmemory_limit): Cast sbrk's returned value to char *.
22797 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

22803 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22804 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
22805 to use the following functions instead of these macros.
22806 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
22807 EMACS_INT, since callers assume the returned value fits in int.
22808 (upcase1): Likewise, for UPCASE_TABLE.
22809 (uppercasep, lowercasep, upcase): New static inline functions.
22810 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

22820 (regex_compile, re_match_2_internal): Mark locals as initialized.
22821 (RETALLOC_IF): Define only if needed.
22822 (WORDCHAR_P): Likewise. This one is never needed, but is used
22823 only in a comment talking about a compiler bug, so put inside
22824 the #if 0 of that comment.
22825 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22826 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

22853 New macros, so that the caller can use some names other than
22854 gcpro1, gcpro2, etc.
22855 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22857 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22858 argument, for consistency with GCPRO2_VAR, etc: it is now the
22859 prefix of the variable, not the variable itself. All uses
22861 * dired.c (directory_files_internal, file_name_completion):
22862 Rename locals to avoid shadowing.
22864 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22865 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22866 dired.c's scmp function, had undefined behavior.
22867 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22868 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22869 * buffer.h: ... to here, because these macros use current_buffer,
22870 and the new implementation with inline functions needs to have
22871 current_buffer in scope now, rather than later when the macros
22873 (downcase, upcase1): New static inline functions.
22874 (DOWNCASE, UPCASE1): Reimplement using these functions.
22875 This avoids undefined behavior in expressions like
22876 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22877 from race conditions in accessing the global variables
22878 case_temp1 and case_temp2.
22879 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22880 * lisp.h (case_temp1, case_temp2): Remove their decls.
22881 * character.h (ASCII_CHAR_P): Move from here ...
22882 * lisp.h: ... to here, so that the inline functions mentioned
22883 above can use them.
22885 * dired.c (directory_files_internal_unwind): Now static.
22887 * fileio.c (file_name_as_directory, directory_file_name):

22890 (file_name_as_directory): Use const pointers when appropriate.
22891 (Fexpand_file_name): Likewise. In particular, newdir might
22892 point at constant storage, so make it a const pointer.
22893 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
22894 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22896 (Fset_file_times, Finsert_file_contents, auto_save_error):

22901 to avoid shadowing.
22903 * marker.c (bytepos_to_charpos): Remove; unused.
22905 * lisp.h (verify_bytepos, count_markers): New decls,
22906 so that gcc does not warn that these functions aren't declared.
22908 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22909 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22910 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22911 (copy_text): Remove unused local var.
22913 * filelock.c (within_one_second): Now static.
22914 (lock_file_1): Rename local to avoid shadowing.
22916 * buffer.c (fix_overlays_before): Mark locals as initialized.
22917 (fix_start_end_in_overlays): Likewise. This function should be
22918 simplified by using pointers-to-pointers, but that's a different
22920 (switch_to_buffer_1): Now static.
22921 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22922 (report_overlay_modification): Rename locals to avoid shadowing.
22924 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
22925 Fix pointer signedness issue.
22926 (sys_subshell): Mark local as volatile if checking for lint,
22927 to suppress a gcc -Wclobbered warning that does not seem to be right.
22928 (MAXPATHLEN): Define only if needed.
22930 * process.c (serial_open, serial_configure): Move decls from here ...
22931 * systty.h: ... to here, so that they can be checked.
22933 * fns.c (get_random, seed_random): Move extern decls from here ...
22934 * lisp.h: ... to here, so that they can be checked.
22936 * sysdep.c (reset_io): Now static.

22943 (DENSE_TABLE_SIZE): Remove; unused.
22944 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
22945 (describe_map_tree):
22946 Rename locals to avoid shadowing.
22948 * keyboard.c: Declare functions static if they are not used elsewhere.
