156 'fullscreen' parameter. Always record previous width and height
157 of the frame, except when switching out of maximized modes, so
158 that they could be restored correctly, instead of resetting to the
159 default frame dimensions. Send SC_RESTORE command to the frame,
160 unless we are going to send SC_MAXIMIZE, to restore the frame

195 * alloc.c: Verify some properties of Lisp_Save_Value's representation.
196 (make_save_value): Change 1st arg from string to enum. All callers

309 * coding.c (detect_ascii): New function.
310 (detect_coding): Set coding->head_ascii and coding->eol_seen only

313 source bytes directly.
314 (produce_chars): Call insert_from_gap with the new arg 0.
315 (encode_coding): Likewise.
316 (decode_coding_gap): Control ASCII optimization by the variable

368 activated, call w32fullscreen_hook, to make sure the new frame
369 dimensions are in effect. (Bug#13937)
371 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
373 * xdisp.c (init_iterator): Simplify because both character and byte
374 positions are either specified or -1. Add eassert. Adjust comment.
375 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
376 character and byte positions can be obtained from marker.

396 Include <sys/param.h> unconditionally, as that works elsewhere and
397 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
398 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin

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

625 * sysdep.c (list_system_processes)
626 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
627 Make it a stub in this case; otherwise the build might fail,
628 and this code hasn't been tested on such hosts anyway.

644 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
645 * filelock.c: Include <c-ctype.h>.
646 (MAX_LFINFO): New top-level constant.
647 (lock_info_type): Remove members pid, boot_time. Add members at,
648 dot, colon. Change user member to be the entire buffer, not a
649 pointer. This allows us to handle the case where a foreign
650 pid or boot time exceeds the local range. All uses changed.
651 (LINKS_MIGHT_NOT_WORK): New constant.
652 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
653 (defined_WINDOWSNT): Remove.
654 (MAKE_LOCK_NAME, file_in_lock_file_name):
655 Always use .#FILE (not .#-FILE) for the file lock,
656 even if it is a regular file.
657 (rename_lock_file): New function.
658 (create_lock_file): Use it.
659 (create_lock_file, read_lock_data):
660 Prefer a symbolic link for the lock file, falling back on a
661 regular file if symlinks don't work. Do not try to create
662 symlinks on MS-Windows, due to security hassles. Stick with
663 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
664 link, rename, unlink, mkstemp) when creating locks, as a GNUish
665 host may be using a Windowsish file system, and cannot use
666 MS-Windows-only system calls. Fall back on mktemp if mkstemp
667 doesn't work. Don't fail merely because of a symlink-contents
668 length limit in the current file system; fall back on regular
669 files. Increase the symlink contents length limit to 8 KiB, this
670 should be big enough for any real use and doesn't crunch the
672 (create_lock_file, lock_file_1, read_lock_data):
673 Simplify allocation of lock file buffers now that they fit in 8 KiB.
674 (lock_file_1): Return error number, not bool. All callers changed.
675 (ELOOP): New macro, if not already defined.
676 (read_lock_data): Return size of lock file contents, not Lisp object.
677 All callers changed. Handle a race condition if some other process
678 replaces a regular-file lock with a symlink lock or vice versa,
679 while we're trying to read the lock.
680 (current_lock_owner): Parse contents more carefully, to help avoid
681 confusing a regular-file lock with some other application's use
682 of the file. Check for lock file contents being too long, or
683 not parsing correctly.
684 (current_lock_owner, lock_file):
685 Allow foreign pid and boot times that exceed the local range.
686 (current_lock_owner, lock_if_free, lock_file):
687 Simplify allocation of lock file contents.
688 * w32.c (sys_rename_replace): New function, containing most of
689 the contents of the old sys_rename.
690 (sys_rename): Use it.
691 (fchmod): New dummy function.
692 * w32.h (sys_rename_replace, fchmod): New decls.
694 2013-03-05 Eli Zaretskii <eliz@gnu.org>
696 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
697 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
698 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
699 <dmantipov@yandex.ru>.
701 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
703 * composite.c (get_composition_id, fill_gstring_header):
704 Use make_uninit_vector where appropriate.
705 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
706 * xselect.c (clean_local_selection_data): Likewise.
708 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
710 Fix misuse of ImageMagick that caused core dump (Bug#13846).
711 * image.c (imagemagick_load_image): Calculate height and width
712 after flattening the image, not before.
714 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
716 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
717 * ftfont.c (ftfont_shape_by_flt): Likewise.
718 * w32uniscribe.c (uniscribe_shape): Likewise.
720 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
722 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
723 The old approach, which fell back on DIR/.#FILE.0 through
724 DIR/.#FILE.9, had race conditions that could not be easily fixed.
725 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
726 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
727 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
728 because the locking mechanism was never reliable in that case).
729 This patch fixes this and other bugs discovered by a code
730 inspection that was prompted by
731 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
732 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
733 to avoid interoperability problems between the MS-Windows and
734 non-MS-Windows implementations. MS-Windows and non-MS-Windows
735 instances of Emacs now ignore each others' locks.
736 * filelock.c (defined_WINDOWSNT): New constant.
737 (MAKE_LOCK_NAME, fill_in_lock_file_name):
738 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
739 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
740 regular files on MS-Windows hosts.
741 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
742 Use SAFE_ALLOCA to avoid problems with long file names.
743 (MAX_LFINFO): Now a local constant, not a global macro.
744 (IS_LOCK_FILE): Remove.
745 (lock_file_1): Don't inspect errno if symlink call succeeds;
747 (lock_file): Document that this function can return if lock
749 (lock_file): Don't access freed storage.
751 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>

755 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
757 * textprop.c: Use bool for booleans.
758 (validate_interval_range, Fadd_text_properties)
759 (Fremove_text_properties): Prefer bool to int when either works.
761 2013-03-02 Eli Zaretskii <eliz@gnu.org>
763 * textprop.c (Fadd_text_properties, Fremove_text_properties):
764 If the interval tree changes as a side effect of calling
765 modify_region, re-do processing starting from the call to
766 validate_interval_range. (Bug#13743)
768 2013-02-28 Eli Zaretskii <eliz@gnu.org>
770 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
773 2013-02-27 Eli Zaretskii <eliz@gnu.org>
775 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
776 _SH_DENYRW flag, instead of emacs_open, to deny any other process
777 access to the lock file until it is written and closed.
780 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
782 * callint.c (Qcall_interactively):
783 * macros.c (Qexecute_kbd_macro):

790 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
792 Minor textprop integer cleanup.
793 * intervals.h, textprop.c (add_text_properties_from_list):
794 Return void, not int, since nobody uses the return value.
795 * textprop.c (validate_plist, add_properties, remove_properties)
796 (Fadd_text_properties):
797 Don't assume list length fits in int.
798 (interval_has_all_properties, interval_has_some_properties)
799 (interval_has_some_properties_list, add_properties, remove_properties)

801 (Fremove_list_of_text_properties, text_property_stickiness):
802 Use bool for booleans.

804 (Fremove_list_of_text_properties):
805 Reindent do-while as per GNU style.

809 Implement CLASH_DETECTION for MS-Windows.
811 * filelock.c [WINDOWSNT]: Include w32.h.
812 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
813 function of that name. Up-case the macro arguments.
814 (IS_LOCK_FILE): New macro.
815 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
816 (create_lock_file): New function, with body extracted from
818 [WINDOWSNT]: Implement lock files by writing a regular file with
819 the lock information as its contents.
820 (read_lock_data): New function, on Posix platforms just calls
822 [WINDOWSNT]: Read the lock info from the file.
823 (current_lock_owner): Call read_lock_data instead of calling
824 emacs_readlinkat directly.
825 (lock_file) [WINDOWSNT]: Run the file name through
828 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
829 just check if the process by that PID exists.
831 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
832 also present, as doing so will fail to error out if the file
835 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
837 * textprop.c (Fadd_text_properties, Fremove_text_properties)
838 (Fremove_list_of_text_properties): Skip all of the intervals in
839 the region between START and END that already have resp. don't
840 have the requested properties, not just the first one.

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

994 2013-02-15 Eli Zaretskii <eliz@gnu.org>
996 * keyboard.c (read_char): Fix calculation of auto-save time out
997 when auto-save-timeout is less than 4. (Bug#13720)
999 * w32proc.c (new_child): Free up to 2 slots of dead processes at a

1008 value that is out of bounds.
1009 (sys_accept): If fd is negative, do not set up the child_process
1010 structure for reading.
1012 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
1014 * composite.c (fill_gstring_header): Remove useless prototype.

1026 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1028 Fix AIX port (Bug#13650).
1029 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
1030 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
1031 was #undeffed earlier, so it cannot be used as a macro here.
1032 Use the constant and not the macro.
1034 2013-02-15 Eli Zaretskii <eliz@gnu.org>

1070 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
1072 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1074 Improve AIX port some more (Bug#13650).
1075 With this, it should be as good as it was in 23.3, though it's
1076 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
1077 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
1078 * unexaix.c (start_of_text): Remove.
1079 (_data, _text): Declare as char[], not int, as AIX manual suggests.
1080 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
1081 (orig_load_scnptr, orig_data_scnptr):
1082 Now off_t, not long, since they are file offsets.
1083 (make_hdr): Use _data, not start_of_data ().
1084 This is the key part of the fix.
1085 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
1086 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
1088 * pre-crt0.c (data_start): Initialize to 1.
1089 This ports to compilers that optimize the external declaration
1090 'int x = 0;' as if it were 'int x;' to shrink the executable.
1092 Improve AIX port (Bug#13650).
1093 This doesn't fix the bug, but it makes progress: Emacs builds now.
1094 * unexaix.c: Include inttypes.h, stdarg.h.
1095 (report_error, report_error_1): Mark as _Noreturn.
1096 (report_error): Don't report the wrong errno.
1097 (report_error_1): Now varargs. All callers changed.
1098 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
1099 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
1100 (write_ptr): Use %p to print address rather than %lx and a cast
1101 to unsigned long. Grow buffer a bit, to be safer.
1103 2013-02-13 Eli Zaretskii <eliz@gnu.org>
1105 * bidi.c (bidi_resolve_neutral): After finding the next
1106 non-neutral character, accept NEUTRAL_ON type as well, because
1107 directional control characters, such as LRE and RLE, have their
1108 type converted to that by bidi_resolve_weak. This avoids aborts
1109 when LRE/RLE follows a run of neutrals.
1110 (bidi_move_to_visually_next): Assert that return value of
1111 bidi_peek_at_next_level is non-negative. Negative values will
1114 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1116 Minor getenv-related fixes.
1117 * callproc.c (Fcall_process_region) [!DOS_NT]:

1119 * callproc.c (init_callproc):
1120 * dispnew.c (init_display):
1121 * sysdep.c (sys_subshell):
1122 Omit unnecessary cast of getenv or egetenv.
1124 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
1126 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
1127 Update dependencies.
1129 2013-02-12 Eli Zaretskii <eliz@gnu.org>
1131 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
1133 (display_line): Set w->region_showing to the value of
1134 it->region_beg_charpos, not to -1. This fixes redisplay
1135 optimization when cursor is moved up after M->. (Bug#13623)
1137 (try_scrolling): Scroll text up more if point is too close to ZV
1138 and inside the scroll margin. This makes sure point is moved
1139 outside the scroll margin in these cases.
1141 * window.h (struct window): region_showing can no longer be
1144 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
1146 Tune by using memchr and memrchr.
1147 * doc.c (Fsnarf_documentation):
1148 * fileio.c (Fsubstitute_in_file_name):
1149 * search.c (find_newline, scan_newline):
1150 * xdisp.c (pos_visible_p, display_count_lines):
1151 Use memchr and memrchr rather than scanning byte-by-byte.
1152 * search.c (find_newline): Rename from scan_buffer.
1153 Omit first arg TARGET, as it's always '\n'. All callers changed.
1155 Clean up read_key_sequence a tiny bit more.
1156 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
1157 (read_key_sequence): Remove unused locals.
1159 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
1161 Clean up read_key_sequence a bit; reread active keymaps after first event.
1162 * keyboard.c (read_char, read_char_x_menu_prompt)
1163 (read_char_minibuf_menu_prompt):
1164 Replace nmaps+maps with a single `map' arg.
1165 (follow_key): Operate on a single map.
1166 (active_maps): New function.
1167 (test_undefined): Also return true for nil bindings.
1168 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
1169 a single (composed) keymap. Remember `first_event' to choose the right
1170 set of active keymaps. Recompute the set of keymaps after receiving
1171 the first event. Remove GOBBLE_FIRST_EVENT.
1172 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
1173 * keyboard.h (read_char): Update declaration.
1174 * lread.c (read_filtered_event): Adjust call to read_char.
1176 2013-02-11 Eli Zaretskii <eliz@gnu.org>
1178 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1179 Don't use the limitation on backwards movement when lines are truncated
1180 in the window. (Bug#13675)
1182 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
1184 * marker.c (set_marker_internal): If desired position is passed
1185 as a marker, avoid call to buf_charpos_to_bytepos.
1186 * window.c (Fset_window_point): Omit redundant type checking.
1187 (Fset_window_start): Likewise. Format comment.
1188 (window_scroll_pixel_based): Use set_marker_restricted_both
1189 with character and byte positions obtained from an iterator.
1190 (Fset_window_configuration): Use set_marker_restricted_both.
1191 * xdisp.c (message_dolog): Likewise.
1193 2013-02-10 Eli Zaretskii <eliz@gnu.org>
1195 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1196 When text lines are longer than window's screen lines, don't move back
1197 too far. This speeds up some redisplay operations. (Bug#13675)
1199 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
1201 * syntax.c (scan_sexps_forward): Fix byte position calculation
1202 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
1204 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
1206 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
1207 that was not needed.
1209 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
1211 Minor hashing refactoring.
1212 * fns.c (SXHASH_REDUCE): Move to lisp.h.
1213 (sxhash_float): Return EMACS_UINT, for consistency with the other
1215 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
1216 non-static inline function and therefore can't use static vars.
1217 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
1218 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
1219 with the other hash functions.
1221 2013-02-09 Eli Zaretskii <eliz@gnu.org>
1223 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
1224 XXXXXX part of the temporary file pattern is not downcased even
1225 when w32-downcase-file-names is non-nil. (Bug#13661)
1227 * xdisp.c (decode_mode_spec): Remove handling of %t.
1229 * msdos.c (careadlinkatcwd): Remove.
1231 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
1233 * lread.c (skip_dyn_bytes): New function (bug#12598).
1234 (read1): Use it. Use getc instead of READCHAR to read bytes.
1235 (load_each_byte): Remove. Update users.
1237 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
1239 * search.c (scan_buffer): Calculate end byte position just once.

1241 (search_command): Use eassert.
1242 * syntax.c (struct lisp_parse_state): New member location_byte.
1243 (scan_sexps_forward): Record from_byte and avoid redundant
1244 character to byte position calculation ...
1245 (Fparse_partial_sexp): ... here. Break too long line.
1247 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
1249 * lisp.h (make_uninit_vector): New function.
1250 * alloc.c (Fvector, Fmake_byte_code):

1264 * xselect.c (selection_data_to_lisp_data): Use it.
1266 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
1268 * coding.c (Fdefine_coding_system_internal): Use AREF where
1269 argument is known to be a vector.
1270 * fns.c (Flocale_info): Likewise for ASET.
1271 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
1272 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
1274 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
1276 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
1279 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
1280 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
1281 updateCollectionBehaviour.
1283 * nsterm.m (NEW_STYLE_FS): Remove.
1284 (ns_last_use_native_fullscreen): New variable.
1285 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
1286 (x_set_window_size): Do not take title bar and tool bar into account
1287 if isFullscreen returns YES.
1288 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
1289 (check_native_fs): New function.
1290 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
1291 (ns_term_init): Remove NEW_STYLE_FS.
1292 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
1293 and tool bar if isFullscreen returns NO.
1294 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
1295 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
1296 with HAVE_NATIVE_FS.
1297 (window:willUseFullScreenPresentationOptions:): New method.
1298 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
1299 Hide toolbar if not enabled (Bug#13444).
1300 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
1301 Restore tool bar if enabled, hide it otherwise (Bug#13444).
1302 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
1303 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
1304 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
1305 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
1306 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
1307 (syms_of_nsterm): Add ns-use-native-fullscreen.
1309 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
1311 * fileio.c (Qchoose_write_coding_system): Now static.
1313 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1315 * xdisp.c (window_buffer_changed): region_showing can be negative,
1316 which still means region is being displayed.
1317 (redisplay_internal): Resurrect code that forced redisplay of the
1318 whole window when showing region and the mark has changed.
1319 Record the new mark position to allow redisplay optimizations.
1320 (display_line): If it->region_beg_charpos is non-zero, set the
1321 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1323 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1324 not bitfield of 1 bit.
1326 2013-02-03 Daniel Colascione <dancol@dancol.org>
1328 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1329 daemon mode works on cygw32 when Emacs is installed and not just
1332 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1334 Avoid file time stamp bug on MS-Windows (Bug#13149).
1335 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1336 as FAT32 doesn't update time stamps when truncating them.
1337 Also, check that a file time stamp is not a multiple of 100 ns;
1338 this should catch all instances of the problem on MS-Windows,
1339 as its native file system resolution is 100 ns or worse, and
1340 checking for a non-multiple of 100 ns should impose only a small
1341 overhead on systems with ns resolution.
1343 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1345 Avoid encoding file names on MS-Windows when they need to be run
1346 through dostounix_filename.
1347 * w32.c (normalize_filename): Accept an additional argument
1348 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1349 downcase it even if w32-downcase-file-names is non-nil.
1350 (dostounix_filename): Accept an additional argument MULTIBYTE and
1351 pass it to normalize_filename.
1352 (emacs_root_dir): Adjust.
1354 * msdos.h (dostounix_filename): Adjust prototype.
1356 * w32.h (dostounix_filename): Adjust prototype.
1358 * msdos.c (dostounix_filename): Accept an additional argument and
1360 (init_environment): Adjust callers of dostounix_filename.
1362 * fileio.c (Ffile_name_directory, file_name_as_directory)
1363 (directory_file_name, Fexpand_file_name)
1364 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1366 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1368 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1369 variables, as egetenv is case-insensitive for DOS_NT.
1371 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1372 with an encoded file name.
1374 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1375 Adjust calls to dostounix_filename.
1377 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1379 * unexw32.c (unexec): Adjust call to dostounix_filename.
1381 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1383 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1386 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1389 * callproc.c (Fcall_process): Make sure program name in PATH and
1390 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1391 is passed to exec/spawnve, which fails unless the file-name
1394 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1395 even if w32-quote-process-args is nil.
1397 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1399 Fix timestamp bug when write-region appends nothing (Bug#13149).
1400 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1401 the file's time stamp doesn't change if Emacs happens to write nothing
1402 to the file, and on a buggy file system this could cause Emacs to
1403 incorrectly infer that the file system doesn't have the bug.
1404 Avoid this problem by inhibiting the inference in this case.
1406 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1408 * window.h (struct window): Convert base_line_number, base_line_pos
1409 and column_number_displayed members from Lisp_Object to ptrdiff_t.
1410 Convert region_showing member from Lisp_Object to bitfield.
1411 Remove sequence_number member. Adjust comments.
1412 * window.c (sequence_number): Remove.
1413 (make_window): Initialize column_number_displayed.
1414 * print.c (print_object): Follow the printed representation of
1415 frames and print window pointer to distinguish between windows.
1416 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
1417 * xdisp.c (wset_base_line_number, wset_base_line_pos)
1418 (wset_column_number_displayed, wset_region_showing): Remove.
1419 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1420 (try_scrolling, try_cursor_movement, redisplay_window)
1421 (try_window_reusing_current_matrix, try_window_id, display_line)
1422 (display_mode_lines, decode_mode_spec): Adjust users.
1423 * .gdbinit (pwinx): Do not print sequence_number.
1425 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1427 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1428 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1429 * dired.c: Include <fcntl.h>.
1430 (open_directory): New function, which uses open and fdopendir
1431 rather than opendir. DOS_NT platforms still use opendir, though.
1432 (directory_files_internal, file_name_completion): Use it.
1433 (file_attributes): New function, with most of the old Ffile_attributes.
1434 (directory_files_internal, Ffile_attributes): Use it.
1435 (file_attributes, file_name_completion_stat): First arg is now fd,
1436 not dir name. All uses changed. Use fstatat rather than lstat +
1438 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1439 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1440 (emacs_readlinkat): New function, with much of the old
1441 Ffile_symlink_p, but with an fd argument for speed.
1442 It uses readlinkat rather than careadlinkatcwd, so that it
1443 need not assume the working directory.
1444 (Ffile_symlink_p): Use it.
1445 * filelock.c (current_lock_owner): Use emacs_readlinkat
1446 rather than emacs_readlink.
1447 * lisp.h (emacs_readlinkat): New decl.
1448 (READLINK_BUFSIZE, emacs_readlink): Remove.
1449 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1450 (emacs_norealloc_allocator, emacs_readlink): Remove.
1451 This stuff is moved to fileio.c.
1452 * w32.c (fstatat, readlinkat): New functions.
1453 (careadlinkat): Don't check that fd == AT_FDCWD.

1463 2013-01-30 Eli Zaretskii <eliz@gnu.org>
1465 * w32.c (sys_open): Zero out the flags for the new file descriptor.
1466 (sys_close): Zero out the flags for the file descriptor before
1467 closing it. (Bug#13546)
1469 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1470 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1471 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1474 * w32.c (w32_get_long_filename, init_environment, readlink):
1475 Support file names encoded in DBCS codepages.
1476 (readlink): Use the current file-name-coding-system, not the ANSI
1477 codepage, to decode and handle targets of symlinks.
1479 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1481 * w32.c (opendir): Now accepts a 'const char *'.
1483 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
1485 Remove obsolete redisplay code. See the discussion at
1486 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
1487 * dispnew.c (preemption_period, preemption_next_check): Remove.
1488 (Vredisplay_preemption_period): Likewise.
1489 (update_frame, update_single_window, update_window, update_frame_1):
1490 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
1491 used, following the 2012-06-22 change.
1493 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1495 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1497 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
1499 * font.c (num_fonts): Remove the leftover from old
1500 debugging code. Adjust comment style here and there.
1501 * insdel.c (insert_1): Remove.
1502 * lisp.h (insert_1): Remove prototype.
1503 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
1505 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1507 * w32.c (max_filename_mbslen): New function.
1508 (normalize_filename, readdir): Use it to detect locales where ANSI
1509 encoding of file names uses a double-byte character set (DBCS).
1510 If a DBCS encoding is used, advance by characters using
1511 CharNextExA, instead of incrementing a 'char *' pointer.
1512 Use _mbslwr instead of _strlwr. (Bug#13515)
1514 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1515 request of memory reservation to 1.7GB. (Bug#13065)
1517 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
1519 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
1520 at check_extra_latin label. (Bug#13505)
1522 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1524 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
1525 Avoid redundant calls to strlen.
1527 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1529 Drop async_visible and async_iconified fields of struct frame.
1530 This is possible because async input is gone; for details, see
1531 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1532 * frame.h (struct frame): Remove async_visible and async_iconified
1533 members, convert garbaged to unsigned bitfield. Adjust comments.
1534 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
1535 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
1536 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
1537 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
1538 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
1540 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
1541 properly. Likewise for obscured.
1543 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
1546 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
1548 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1550 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
1551 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1553 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1555 * xdisp.c (message2, message2_nolog): Remove functions.
1556 (message3, message3_nolog): Extract nbytes and multibyteness directly
1557 from the string. Change all callers.
1558 (message3_nolog): Don't set message_enable_multibyte since set_message
1559 will reset it anyway.
1560 (message1, message1_nolog): Use message3.
1561 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1562 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1563 (set_message): Drop all but the second arg, which has to be a string.
1564 (set_message_1): Simplify now that we know that a1 is NULL and the
1565 second arg is a string.
1566 * frame.h (struct frame): Remove `message_buf' field.
1567 Use glyphs_initialized_p instead.
1568 (FRAME_MESSAGE_BUF): Remove macro.
1569 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
1570 * lisp.h (message2, message2_nolog): Remove declarations.
1571 (message3, message3_nolog): Update declarations.
1572 * keyboard.c (read_char_minibuf_menu_text)
1573 (read_char_minibuf_menu_width): Remove vars.
1574 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
1575 to correctly handle multibyte strings.
1576 * frame.c (delete_frame): Don't free message_buf any more.
1577 * editfns.c (message_text, message_length): Remove vars.
1578 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1579 * fileio.c (auto_save_error): Use message3 instead of message2.
1580 * dispnew.c (adjust_frame_message_buffer): Remove function.
1582 2013-01-23 Eli Zaretskii <eliz@gnu.org>
1584 * w32term.c (w32fullscreen_hook): Account correctly for the screen
1585 real estate used for the tool bar and the menu bar.
1587 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
1589 * insdel.c (prepare_to_modify_buffer): Force redisplay if
1590 hidden buffer is prepared to modification (Bug#13164).
1592 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1594 * window.h (struct window): Change window_end_valid member from
1595 Lisp_Object to a bitfield. Adjust comments.
1596 (wset_window_end_valid): Remove.
1597 * window.c (adjust_window_count): Clear window_end_valid.
1598 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
1599 (Fwindow_line_height, set_window_buffer, Frecenter)
1600 (Fsplit_window_internal, Fdelete_other_windows_internal)
1601 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
1602 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
1603 * xdisp.c (check_window_end, reconsider_clip_changes)
1604 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1605 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1606 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1608 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1610 * xdisp.c (mark_window_display_accurate): Simplify the loop
1611 assuming that the only one of vchild, hchild or buffer window
1612 slots is non-nil. Call mark_window_display_accurate_1 for
1613 the leaf windows only.
1614 (mark_window_display_accurate_1): Always assume leaf window.
1617 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1619 * emacs.c (Qkill_emacs_hook): Now static.
1621 * fileio.c (Finsert_file_contents): Simplify.
1622 Remove unnecessary assignments and tests.
1624 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1626 * w32.c (acl_set_file): Don't test for errors unless
1627 set_file_security returns FALSE. Avoids spurious errors when
1630 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1632 * fileio.c (Finsert_file_contents): Revert code introduced at
1633 2013-01-18 in favor of the simpler and generally better fix.
1634 Save stack space by removing 'buffer' and reusing 'read_buf'
1637 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1639 * lisp.h (eabs): Define unconditionally (Bug#13419).
1640 The old "#if !defined (eabs)" was an unnecessary revenant of back
1641 when this macro was called "abs". Document 'eabs' better.
1643 2013-01-19 Glenn Morris <rgm@gnu.org>
1645 * fns.c (Frandom): Doc fix.
1647 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1649 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1650 segfault when there are lots of overlays.
1652 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1653 when there are lots of overlays.
1654 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1655 for the details and a way to reproduce.
1657 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1659 * fileio.c: Use O_APPEND to append.
1660 This corresponds better to the natural interpretation of "append",
1661 and avoids the need to open the output file twice, or to invoke
1662 lseek when APPEND is neither nil nor a number.
1663 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1664 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1665 file possibly twice, and lseeking to its end; this avoids the
1666 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1667 at the same time: the combination is never needed and apparently
1668 it doesn't work with DOS_NT.
1670 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1671 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1673 Allow floating-point file offsets.
1674 Problem reported by Vitalie Spinu in
1675 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1676 * fileio.c (emacs_lseek): Remove.
1677 (file_offset): New function.
1678 (Finsert_file_contents, Fwrite_region): Use it.
1680 2013-01-19 Chong Yidong <cyd@gnu.org>
1682 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1683 aborting on Fsignal (Bug#13289).
1685 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1687 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1688 set_file_security as failure due to insufficient privileges.
1689 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1690 (fstat): Return owner and group like 'stat' and 'lstat' do.
1692 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1694 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1695 The bug was observed on Ubuntu operating inside a virtual machine,
1696 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1697 The workaround introduces a race condition on non-buggy hosts,
1698 but it's an unlikely race and anyway there's a nearly identical
1699 nearby race that can't be fixed.
1700 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1702 (Fwrite_region): Test for file system time stamp bug.
1703 (init_fileio): New function.
1704 * lisp.h (init_fileio): Declare it.
1705 * emacs.c (main): Call it.
1707 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1708 and make it more consistent with other stat-failure diagnostics.
1710 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
1712 Fix crash when inserting data from non-regular files.
1713 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
1714 for the error description produced by valgrind.
1715 * fileio.c (read_non_regular): Rename to read_contents.
1716 Free Lisp_Save_Value object used to pass parameters.
1717 (read_non_regular_quit): Rename to read_contents_quit.
1718 (Finsert_file_contents): Redesign internal file reading loop to adjust
1719 gap and end positions after each read and so help make_gap to work
1720 properly. Do not signal an I/O error too early and so do not leave
1721 not yet decoded characters in a buffer, which was the reason of
1722 redisplay crash. Use list2 to build return value. Adjust comments.
1724 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1726 Close a race when statting and reading files (Bug#13149).
1727 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1728 This avoids a race if the file is renamed between stat and open.
1729 This race is not the problem originally noted in Bug#13149;
1730 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
1732 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

1740 * alloc.c (format_save_value): Rename to make_save_value.
1741 (make_save_pointer): New function.
1742 (record_xmalloc): Use make_save_pointer.
1743 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
1744 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
1745 Change users of make_save_value to make_save_pointer.

1762 (map_keymap_char_table_item): Adjust accordingly.
1763 * fileio.c (non_regular_fd, non_regular_inserted)
1764 (non_regular_nbytes): Remove.
1765 (Finsert_file_contents): Convert trytry to ptrdiff_t.
1766 Use format_save_value to pass parameters to read_non_regular.
1767 (read_non_regular): Use XSAVE_ macros to extract parameters.
1769 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
1771 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
1773 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1775 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
1776 extraction from any Lisp_Save_Value slot. Add type checking.
1777 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
1778 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
1779 * xselect.c: All users changed.
1781 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

1792 (save_excursion_restore): Use XSAVE_OBJECT.
1794 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
1796 Avoid needless casts with XSAVE_POINTER.
1797 * alloc.c (mark_object) [GC_MARK_STACK]:
1798 * dired.c (directory_files_internal_unwind):
1799 * fileio.c (do_auto_save_unwind):
1800 * gtkutil.c (pop_down_dialog):
1801 * keymap.c (map_keymap_char_table_item):
1802 * lread.c (load_unwind):
1803 * nsmenu.m (pop_down_menu):
1804 * print.c (print_object) [GC_MARK_STACK]:
1805 * xfns.c (clean_up_file_dialog):
1806 * xmenu.c (cleanup_widget_value_tree):
1807 Omit casts between XSAVE_POINTER and a pointer type.
1809 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
1811 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
1812 * eval.c (eval_sub): Protect `form' from being GCed before its
1813 car and cdr becomes protected with the backtrace entry.
1815 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
1817 Make Lisp_Save_Value more versatile storage for up to four objects.

1820 (XSAVE_POINTER): New macro.
1821 (XSAVE_INTEGER): Likewise.
1822 (allocate_misc): Add prototype.
1823 (free_misc): Likewise.
1824 * alloc.c (allocate_misc): Now global.
1825 (free_misc): Likewise. Adjust comment.
1826 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
1827 (free_save_value): Likewise.
1828 (mark_object): Likewise.
1829 * editfns.c (save_excursion_save): Pack everything within
1830 Lisp_Save_Value and so avoid xmalloc.
1831 (save_excursion_restore): Adjust to match new layout. Use free_misc
1832 because we do not allocate extra memory any more. Add eassert.
1833 * print.c (print_object): New code to print Lisp_Save_Value. Do not
1834 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
1835 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
1836 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:

1848 Fix SIGDANGER handlers, for AIX (Bug#13408).
1849 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
1850 Move handlers here from emacs.c; they were out of place.
1852 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>

1874 (nsfont_list_family): Add block/unblock_input calls.
1875 (nsfont_open): Move block_input earlier. Add unblock_input before early
1877 (nsfont_draw): Add block/unblock_input calls.

1902 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
1904 Avoid unnecessary byte position calculation for the gap movement.
1905 Since all users of move_gap do CHAR_TO_BYTE for other purposes
1906 anyway, all of them should use move_gap_both instead.

1916 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
1918 * term.c (init_tty): Use them instead of rolling our own code.
1919 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
1920 switches from 'signal' to 'pthread_sigmask', which is safer in
1921 multithreaded applications.
1922 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
1923 which has already arranged for that.
1924 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
1925 This is the main part of the bug fix.

1937 predicate, which is how it's really used now. Adjust comment.
1938 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
1939 * buffer.c (buffer_slot_type_mismatch): Remove.
1940 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
1941 predicate. Adjust comment.

1944 left-margin-width, right-margin-width, left-fringe-width,
1945 right-fringe-width, scroll-bar-width and buffer-display-count.
1946 Use Qstringp for default-directory, buffer-file-name,
1947 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1948 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
1950 * data.c (store_symval_forwarding): Adjust to call the predicate.
1952 2013-01-09 Juanma Barranquero <lekktu@gmail.com>

1966 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
1967 (make_gap_1): New function to adjust the gap of any buffer.
1968 * coding.c (coding_alloc_by_making_gap): Use it.
1969 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
1970 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.

1986 2013-01-06 Chong Yidong <cyd@gnu.org>
1988 * keyboard.c (echo_add_char): New function, factored out from

1993 trailing dash is properly added.
1995 2013-01-05 Eli Zaretskii <eliz@gnu.org>
1997 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
1998 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
1999 digits for buffer positions, before misalignment starts.
2000 Display "0" for integer "object" field.
2001 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
2002 Display the newline glyph more unambiguously.
2004 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2006 * nsterm.m (ns_draw_underwave):
2007 * w32term.c (w32_draw_underwave):
2008 * xterm.c (x_draw_underwave): Make underwave look more triangular
2009 and also degrade gracefully for small fonts. (Bug#13000)
2011 * nsterm.m (ns_draw_text_decoration):
2012 * w32term.c (x_draw_glyph_string):
2013 * xterm.c (x_draw_glyph_string): Don't use previous underline
2014 thickness and position if previous underline type is underwave.
2016 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
2018 * fileio.c (Ffile_acl): Undocument return format.
2020 2013-01-02 Glenn Morris <rgm@gnu.org>
2022 * keymap.c (Fkey_description): Doc fix. (Bug#13323)

2032 * lread.c (read_list):
2033 * minibuf.c (Ftry_completion):
2034 * term.c (tty_ins_del_lines):
2035 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
2036 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
2038 2012-12-31 Eli Zaretskii <eliz@gnu.org>
2040 * w32.c (unsetenv): Set up the string passed to _putenv
2042 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
2043 for the bug this caused.
2045 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
2047 * coding.c (Qmac): Now static.
2049 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
2051 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
2052 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

2059 by TOOLBAR_TOP_WIDGET.
2060 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
2061 Check toolbar_is_packed.
2062 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on

2064 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
2066 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2067 (xg_update_menubar): Update title only if
2068 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2069 (xg_update_submenu): Skip tearoff only if
2070 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2071 (xg_initialize): Initialize xg_detached_menus only if
2072 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2074 * xterm.h (struct x_output): Surround handlebox_widget with
2075 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
2076 toolbar_in_hbox is bool.
2078 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
2080 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
2081 (LIBS_GNUSTEP): Define.
2082 (LIBES): Add $(LIBS_GNUSTEP).

2085 2012-12-30 Eli Zaretskii <eliz@gnu.org>
2087 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
2088 continuation glyph on a TTY with an indication of an empty line.
2091 2012-12-29 Eli Zaretskii <eliz@gnu.org>
2093 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
2094 file's SELinux context or ACLs successfully set, nil otherwise.
2096 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.

2099 SetEvent and WaitForSingleObject.
2101 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
2103 Port EXTERNALLY_VISIBLE to Clang 3.2.
2104 * conf_post.h (__has_attribute): New macro.
2105 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
2107 2012-12-27 Glenn Morris <rgm@gnu.org>
2109 * cygw32.c (Fcygwin_convert_file_name_to_windows)
2110 (Fcygwin_convert_file_name_from_windows): Doc fixes.
2112 2012-12-27 Eli Zaretskii <eliz@gnu.org>
2114 * fileio.c (file_name_as_directory, directory_file_name):
2115 Accept an additional argument MULTIBYTE to indicate whether the input C
2116 came from a multibyte or a unibyte Lisp string; all callers
2117 adjusted. Don't assume the input string is always multibyte.
2119 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
2120 don't ENCODE_FILE them, and return a unibyte string if the input
2122 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
2123 don't assume the input strings will always be multibyte. If the
2124 input strings are multibyte, decode strings obtained from C
2127 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2129 * lisp.h (toplevel): Add two notices to the comment about
2130 defining a new Lisp data type.

2134 * alloc.c (valid_lisp_object_p): Adjust comment.
2136 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2138 * keyboard.c (record_asynch_buffer_change): Initialize an event
2139 only if it's really needed.
2140 * frame.h (enum output_method): Remove output_mac member since
2141 it's a leftover from the deleted code.
2142 * frame.c (Fframep): Adjust user here ...
2143 * terminal.c (Fterminal_live_p): ... and here.
2144 * coding.c (Qmac): Now here because it's only used to denote
2145 end-of-line encoding type.
2146 (syms_of_coding): DEFSYM it.
2147 * frame.h (Qmac): Remove duplicated declaration.
2149 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
2151 * window.c (select_window_1): Now static, since it's used only here.
2153 2012-12-25 Eli Zaretskii <eliz@gnu.org>
2155 * window.c (window_body_cols): Subtract display margins from the
2156 window body width on TTYs as well. See
2157 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
2158 for the original report.
2160 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
2162 * xdisp.c (redisplay_window): Remove inner local variable
2163 because the outer shadowed one has the same meaning.
2164 * xterm.h (struct x_output): Remove toolbar_detached member since it's
2166 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
2167 (xg_create_tool_bar): Adjust users.
2169 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
2171 * buffer.h (BUF_COMPACT): New macro to follow the common style.
2172 * buffer.c (Fget_buffer_create): Use it to set compact field of
2173 struct buffer_text to avoid accessing an uninitialized value
2174 when compact_buffer is called for the first time.
2175 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
2176 (Fset_buffer_modified_p): Use buffer_window_count to check
2177 whether the buffer is displayed in some window.
2178 * xdisp.c (message_dolog): Likewise.
2180 2012-12-23 Eli Zaretskii <eliz@gnu.org>
2182 * w32.c (acl_set_file): If setting the file security descriptor
2183 fails, and the new DACL is identical to the existing one, silently
2184 return success. This fixes problems for users backing up their
2185 own files without having the necessary privileges for setting
2186 security descriptors.
2188 * w32proc.c (reader_thread): Do not index fd_info[] with negative
2190 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
2191 after WaitForSingleObject returns normally. This expedites reader
2192 thread shutdown when delete_child triggers it.
2193 (reap_subprocess): More accurate commentary for why we call
2194 delete_child only when cp->fd is negative.
2196 * w32.c (sys_close): Do not call delete_child on a subprocess
2197 whose handle is not yet closed. Instead, set its file descriptor
2198 to a negative value, so that reap_subprocess will call
2199 delete_child on that subprocess when its SIGCHLD arrives.
2200 This avoids closing handles used for communications between sys_select
2201 and reader_thread, which doesn't give sys_select a chance to
2202 notice that the process exited and invoke the SIGCHLD handler for
2205 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
2207 * nsfns.m (Fns_do_applescript): Run event loop until script has
2208 been executed (Bug#12969).

2216 2012-12-22 Eli Zaretskii <eliz@gnu.org>
2218 * w32term.c (w32fullscreen_hook): New function.
2219 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
2221 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2223 * fileio.c (Finsert_file_contents): Doc fix.
2225 * w32proc.c (new_child, delete_child, find_child_pid): For a
2226 subprocess, consider its slot being in use as long as its process
2227 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2228 slot when a new process is started immediately after killing
2229 another one, without waiting enough time for the first process to
2230 be reaped and resources allocated for it be orderly freed.
2232 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2234 2012-12-21 Chong Yidong <cyd@gnu.org>
2236 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
2238 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
2240 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2242 * w32.c (get_name_and_id): Always pass NULL as the first argument
2243 of lookup_account_sid. Avoids crashes with UNC file names that
2244 refer to DFS domains, not to specific machine names. (Bug#12621)
2245 Remove now unused argument FNAME; all callers changed.
2246 (get_file_owner_and_group): Remove now unused argument FNAME; all
2249 2012-12-21 Chong Yidong <cyd@gnu.org>
2251 * editfns.c (Finsert_char): Since read-char-by-name now signals an
2252 error for invalid chars, don't check for a nil return value.
2254 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2256 Avoid calls to CHAR_TO_BYTE if byte position is known.
2257 * editfns.c (make_buffer_string_both): Use move_gap_both.
2258 (Fbuffer_string): Use make_buffer_string_both.
2259 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
2261 (buf_bytepos_to_charpos): Likewise.
2262 (charpos_to_bytepos): Remove.
2263 * fileio.c (Finsert_file_contents): Use move_gap_both.
2264 * search.c (Freplace_match): Likewise.
2265 * process.c (process_send_region): Likewise. Use convenient
2266 names for byte positions.
2267 * lisp.h (charpos_to_bytepos): Remove prototype.
2268 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
2269 * insdel.c (move_gap): Likewise.

2277 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
2278 (redisplay_internal): Don't bother selecting the frame to get the
2279 proper value of frame-local variables (bug#13225).
2281 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2283 * textprop.c (set_text_properties_1): Do not allow NULL interval.
2284 Rename 4th argument since it may be buffer or string. Adjust comment.
2285 * intervals.c (graft_intervals_info_buffer): Find an interval here.
2287 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
2289 * coding.c (Fdetect_coding_region): Do not check start and end with
2290 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
2291 (code_convert_region): Likewise.
2293 2012-12-18 Eli Zaretskii <eliz@gnu.org>
2295 * w32.c (acl_get_file, acl_set_file): Run the file name through
2296 map_w32_filename, and resolve any symlinks in the file name, like
2298 (acl_set_file): Call revert_to_self, if any privileges were
2301 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
2303 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
2304 ($(BLD)/w32.$(O)): Update dependencies.
2306 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
2308 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
2309 propagate redisplay's scrolling (if any) to the right window.
2310 (redisplay_internal): Use ensure_selected_frame.
2311 (display_mode_lines): Complete last fix.
2312 * window.c (select_window_1): New func, extracted from select_window.
2313 (select_window): Use it.
2314 * window.h (select_window_1): Declare.
2316 2012-12-17 Eli Zaretskii <eliz@gnu.org>
2318 Emulate Posix ACL APIs on MS-Windows.
2319 * w32.c: Include sddl.h and sys/acl.h.
2320 (SDDL_REVISION_1): Define if not already defined.

2342 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2343 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2344 for some of that bug's symptoms can now cause Emacs to abort.
2345 Remove the workaround.
2346 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2347 The bug that caused SIGCHLD to get lost has been fixed, and the
2348 workaround for it can now cause Emacs to abort.
2350 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2352 * sysdep.c (emacs_abort): Bump backtrace size to 40.

2358 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
2359 (Fcopy_file): Change last arg to `preserve_extended_attributes'
2360 and copy ACL entries of file in addition to SELinux context if set.
2361 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
2363 * Makefile.in (LIBACL_LIBS): New macro.

2378 * w32proc.c (new_child): Initialize input_file and
2379 pending_deletion members of the child.
2380 (delete_child): Delete the child's temporary input file, if any,
2381 that is pending deletion.
2382 (register_child): First argument is now pid_t.
2383 (record_infile, record_pending_deletion): New functions.
2384 (reap_subprocess): Fix a typo in DebPrint string.
2385 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
2387 * fileio.c (internal_delete_file): Return an int again: non-zero
2388 if delete-file succeeds, zero otherwise.
2390 * lisp.h (internal_delete_file): Adjust prototype.
2392 * callproc.c (Fcall_process): Don't overwrite infile with result
2394 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
2395 asynchronous subprocess, record the name of the input file name,
2397 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
2398 delete the file, record it as pending deletion when the subprocess
2401 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2403 * editfns.c [HAVE_PWD_H]: Include grp.h.

2421 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2423 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
2424 try to get accurate owner and group information from NT file
2425 security APIs. This is to make most callers of 'stat' and
2426 'lstat', which don't need that information, much faster.
2428 * dired.c (Ffile_attributes) [WINDOWSNT]:
2429 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2430 owner and group information from 'lstat'.
2432 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2434 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2435 as that confuses set-auto-coding, so insist on the head-read
2436 returning the full 1024 bytes. Let lseek compute the tail offset;
2437 less work for us. Do not ignore I/O errors when reading the tail.

2460 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
2461 files, fixing a regression from 24.2.
2462 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
2464 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2466 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2467 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2468 Remove unnecessary S_ISLNK test, as (contra the comments) this
2469 function can't copy symlinks. Improve quality of error message
2470 when attempting to copy files that are neither regular files nor

2489 * inotify.c (inotify_callback): Generate an Emacs event for every
2490 incoming inotify event.
2492 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2494 * xdisp.c (handle_face_prop): Fix logic of computing
2495 it->start_of_box_run_p.

2502 left_box_line_p and right_box_line_p flags of the glyph for R2L
2503 glyph rows. (Bug#13011)

2553 (hinst): Remove unneeded extern declaration.
2554 (_start): Remove initialization of above variables; remove

2774 * frame.c (make_frame): Do not set window's buffer to t.
2775 * window.c (Fsplit_window_internal): Likewise. Previously it was

2804 * keyboard.c (command_loop_1): Remove prototype.
2805 (command_loop_2, top_level_1): Add static to match prototype.
2807 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
2809 Fix a recently-introduced delete-process race condition.
2810 * callproc.c, process.h (record_kill_process):
2811 New function, containing part of the old call_process_kill.
2812 (call_process_kill): Use it.
2813 This does not change call_process_kill's behavior.
2814 * process.c (Fdelete_process): Use record_kill_process to fix a
2815 race condition that could cause Emacs to lose track of a child.
2817 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2819 Avoid code duplication between prev_frame and next_frame.
2820 * frame.c (candidate_frame): New function. Add comment.
2821 (prev_frame, next_frame): Use it. Adjust comment.
2823 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2825 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2826 fails, signal an error instead of continuing with an empty
2828 Encode expanded temp file pattern before passing it to mkstemp or
2831 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2832 Encode the file name before passing it to dostounix_filename, in
2833 case it will downcase it (under w32-downcase-file-names).
2836 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2838 Minor call-process cleanups.
2839 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2840 at the same time as other platforms, to simplify analysis.
2841 No need for fd0_volatile since we have synch_process_fd.
2842 Avoid needless emacs_close; arg is always negative.
2844 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2846 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2849 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2851 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2852 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2853 and mouse_face_hidden members to a bitfields.
2854 * frame.h (struct frame): Remove set-but-not-used space_width member.
2855 (FRAME_SPACE_WIDTH): Remove.
2856 * nsterm.m, w32term.c, xterm.c: Adjust users.
2857 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2858 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2859 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2860 members to a bitfields.
2862 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2864 Don't let call-process be a zombie factory (Bug#12980).
2865 Fixing this bug required some cleanup of the signal-handling code.
2866 As a side effect, this change also fixes a longstanding rare race
2867 condition whereby Emacs could mistakenly kill unrelated processes,
2868 and it fixes a bug where a second C-g does not kill a recalcitrant
2869 synchronous process in GNU/Linux and similar platforms.
2870 The patch should also fix the last vestiges of Bug#9488,
2871 a bug which has mostly been fixed on the trunk by other changes.
2872 * callproc.c, process.h (synch_process_alive, synch_process_death)
2873 (synch_process_termsig, sync_process_retcode):
2874 Remove. All uses removed, to simplify analysis and so that
2875 less consing is done inside critical sections.
2876 * callproc.c (call_process_exited): Remove. All uses replaced
2877 with !synch_process_pid.
2878 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2879 These take the role of what used to be in unwind-protect arg.
2881 (block_child_signal, unblock_child_signal):
2882 New functions, to avoid races that could kill innocent-victim processes.
2883 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2884 (call_process_kill): Record killed processes as deleted, so that
2885 zombies do not clutter up the system. Do this inside a critical
2886 section, to avoid a race that would allow the clutter.
2887 (call_process_cleanup): Fix code so that the second C-g works again
2888 on common platforms such as GNU/Linux.
2889 (Fcall_process): Create the child process in a critical section,
2890 to fix a race condition. If creating an asynchronous process,
2891 record it as deleted so that zombies do not clutter up the system.
2892 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2893 light of these changes. Omit unnecessary call to emacs_close
2894 before failure, as the unwind-protect code does that.
2895 * callproc.c (call_process_cleanup):
2896 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2897 * process.c (record_deleted_pid): New function, containing
2898 code refactored out of Fdelete_process.
2899 (Fdelete_process): Use it.
2900 (process_status_retrieved): Remove. All callers changed to use
2901 child_status_change.
2902 (record_child_status_change): Remove, folding its contents into ...
2903 (handle_child_signal): ... this signal handler. Now, this
2904 function is purely a handler for SIGCHLD, and is not called after
2905 a synchronous waitpid returns; the synchronous code is moved to
2906 wait_for_termination. There is no need to worry about reaping
2907 more than one child now.
2908 * sysdep.c (get_child_status, child_status_changed): New functions.
2909 (wait_for_termination): Now takes int * status and bool
2910 interruptible arguments, too. Do not record child status change;
2911 that's now the caller's responsibility. All callers changed.
2912 Reimplement in terms of get_child_status.
2913 (wait_for_termination_1, interruptible_wait_for_termination):
2914 Remove. All callers changed to use wait_for_termination.
2915 * syswait.h: Include <stdbool.h>, for bool.
2916 (record_child_status_change, interruptible_wait_for_termination):
2918 (record_deleted_pid, child_status_changed): New decls.
2919 (wait_for_termination): Adjust to API changes noted above.
2921 * bytecode.c, lisp.h (Qbytecode): Remove.
2922 No longer needed after 2012-11-20 interactive-p changes.
2924 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2926 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2927 the scroll margin, move point outside the margin. (Bug#13055)
2929 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2931 * gtkutil.c (my_log_handler): New function.
2932 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2934 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2936 * lisp.h (modify_region): Rename to...
2937 (modify_region_1): ...new prototype.
2938 * textprop.c (modify_region): Now static. Adjust users.
2939 * insdel.c (modify_region): Rename to...
2940 (modify_region_1): ...new function to work with current buffer.
2941 Adjust comment and users. Use true and false for booleans.
2943 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2945 * alloc.c (free_save_value): New function.
2946 (safe_alloca_unwind): Use it.
2947 * lisp.h (free_save_value): New prototype.
2948 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2950 (save_excursion_restore): Adjust to match saved data structure.
2951 Use free_save_value to offload some work from GC. Drop obsolete
2954 2012-12-03 Chong Yidong <cyd@gnu.org>
2956 * fileio.c (Vauto_save_list_file_name): Doc fix.
2958 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2960 * w32fns.c: Remove prototype of atof.
2961 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2963 (file_dialog_callback): Make it UINT_PTR.
2965 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2968 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2969 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2972 2012-12-03 Glenn Morris <rgm@gnu.org>
2974 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2976 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2978 Fix xpalloc confusion after memory is exhausted.
2979 * alloc.c (xpalloc): Comment fix.
2980 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2981 and signals an error, do not clear charset_table_size, as
2982 charset_table is still valid.
2983 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2985 Use execve to avoid need to munge environ (Bug#13054).
2986 * callproc.c (Fcall_process):
2987 * process.c (create_process):
2988 Don't save and restore environ; no longer needed.
2989 * callproc.c (child_setup):
2990 Use execve, not execvp, to preserve environ.
2992 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2994 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2996 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2998 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2999 display for sliced images (Bug#10500).
3001 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
3003 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
3005 * doc.c (Fdocumentation): Re-add handling of function-documentation,
3006 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
3008 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
3010 * xdisp.c (window_outdated): Remove eassert since it hits
3011 some suspicious corner cases (see Bug#13007 and Bug#13012).
3012 (mode_line_update_needed): New function.
3013 (redisplay_internal, redisplay_window): Use it.
3014 (ensure_selected_frame): New function.
3015 (redisplay_internal, unwind_redisplay): Use it.
3016 (redisplay_internal): Move comment about buffer_shared...
3017 (buffer_shared_and_changed): ...near to its real use.
3019 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
3021 * callproc.c (Fcall_process): Don't misreport vfork failure.
3023 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
3025 * callproc.c (Fcall_process): Fix vfork portability problems.
3026 Do not assume that fd[0], count, filefd, and save_environ survive
3027 vfork. Fix bug whereby wrong errno value could be reported for
3028 pipe failure. Some minor cleanups, too, as follows. Move buf and
3029 bufsize to the context where they're needed. Change new_argv to
3030 be of type char **, as this is more convenient and avoids casts.
3031 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
3032 Now local constants, not macros.
3034 2012-11-18 Kenichi Handa <handa@gnu.org>
3036 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
3037 for the variable "f".
3039 2012-11-13 Kenichi Handa <handa@gnu.org>
3041 * font.c (font_unparse_xlfd): Exclude special characters from the
3042 generating XLFD name.
3044 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

3068 highlighting on the frame was cleared. Prevents assertion
3069 violations when repeatedly clicking on the "Top" link of the
3070 "bread-crumbs" in Info buffers.

3084 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
3085 between bpos_covered and bpos_max. This fixes cursor display when
3086 several display strings follow each other.
3088 * .gdbinit (pgx): If the glyph's object is a string, display the
3089 pointer to string data, rather than the value of the string object
3090 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
3092 * indent.c (Fvertical_motion): If the starting position is covered
3093 by a display string, return to one position before that, to avoid
3094 overshooting it inside move_it_to. (Bug#12930)
3096 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>

3107 Drop unused pending_menu_activation member.
3108 * xterm.h (struct x_output): Drop outdated #if 0 code.
3109 Use bitfields for explicit_parent, asked_for_visible,
3110 has_been_visible and net_wm_state_hidden_seen members.

3115 of a literal "/". (Bug#12955)
3116 (gl-stamp): Invoke fc.exe directly, not through cmd.

3121 * dired.c: Assume HAVE_DIRENT_H.
3122 (NAMLEN): Remove, replacing with ...
3123 (dirent_namelen): New function. All uses changed. Use the GNU macro
3124 _D_EXACT_NAMELEN if available, as it's faster than strlen.
3125 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
3126 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
3127 * makefile.w32-in (DIR_H): Remove. All uses replaced with
3129 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
3130 * ndir.h: Rename to ../nt/inc/dirent.h.
3131 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
3132 Do not include <dirent.h>; no longer needed.
3133 * w32.c: Include <dirent.h> rather than "ndir.h".
3135 2012-11-23 Chong Yidong <cyd@gnu.org>
3137 * xftfont.c (xftfont_open): Remove duplicate assignment.
3139 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3141 * alloc.c (Fgarbage_collect): Unblock input after clearing
3142 gc_in_progress to avoid note_mouse_highlight glitch with GC.
3143 * frame.h (FRAME_MOUSE_UPDATE): New macro.
3144 * msdos.c (IT_frame_up_to_date): Use it here...
3145 * w32term.c (w32_frame_up_to_date): ...here...
3146 * xterm.c (XTframe_up_to_date): ...and here...
3147 * nsterm.m (ns_frame_up_to_date): ...but not here.

3159 'tail' and 'frame' local variables.
3161 2012-11-22 Eli Zaretskii <eliz@gnu.org>
3163 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
3164 with Windows system header.

3185 * emacs.c (main): Set the G_SLICE environment variable for all
3186 Cygwin builds, not just GTK builds. See
3187 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
3189 2012-11-21 Eli Zaretskii <eliz@gnu.org>
3191 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3192 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
3193 Define for the MSVC compiler.
3195 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
3197 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
3198 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
3199 dostounix_filename. Prevents crashes down the road, because
3200 dostounix_filename assumes it gets a unibyte string.
3201 Reported by Michel de Ruiter <michel@sentient.nl>, see

3250 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3252 * w32select.c: Include w32common.h before w32term.h, so that
3253 windows.h gets included before w32term.h uses some of its
3254 features, see below.
3256 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3258 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

3264 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
3265 (ns_select): Return at once if events are held (Bug#12834).
3267 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3269 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3270 Needed following 2012-10-20 change. (Bug#12902)
3272 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3274 * w32proc.c (waitpid): Remove unused label get_result.
3276 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3278 * makefile.w32-in (SYSWAIT_H): New macro.
3279 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3280 ($(BLD)/sysdep.$(O)): Update dependencies.
3282 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3284 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
3285 * callproc.c (relocate_fd): Assume F_DUPFD.
3286 * emacs.c, term.c (O_RDWR): Remove.
3287 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3288 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3289 * nsterm.m: Assume <fcntl.h> exists.
3290 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3291 (create_pty, Fmake_network_process, server_accept_connection)
3292 (wait_reading_process_output, init_process_emacs):
3294 (wait_reading_process_output): Put in a special case for WINDOWSNT
3295 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3296 It's not clear this is needed, but it's a more-conservative change.
3297 (create_process): Assume FD_CLOEXEC.
3298 (create_process, create_pty): Assume O_NOCTTY.
3299 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3300 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3301 Omit if not DOS_NT, since F_GETFL is not defined there.
3302 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3303 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3305 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3306 lack it, since gnulib guarantees this.
3307 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3309 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3311 * w32.c (faccessat): Pretend that directories have the execute bit
3312 set. Emacs expects that, e.g., in files.el:cd-absolute.
3314 * w32proc.c (create_child): Don't clip the PID of the child
3315 process to fit into an Emacs integer, as this is no longer a
3317 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3318 reaping only the process specified by PID argument, if that is
3319 positive. Use PID instead of dead_child to know which process to
3320 reap. Wait for the child to die only if WNOHANG is not in
3322 (sys_select): Don't set dead_child.
3324 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3325 as it is no longer needed.
3327 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3329 (record_child_status_change): Remove the setting of
3330 record_at_most_one_child for the !WNOHANG case.
3332 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3334 Fix problems in ns port found by static checking.
3335 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3336 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3337 not to process group.
3338 (ns_select): Use emacs_write, not write, as that's more robust
3339 in the presence of signals.
3340 (fd_handler:): Check for read errors.
3342 2012-11-16 Glenn Morris <rgm@gnu.org>
3344 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3346 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3348 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3350 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3352 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3353 use the same value of thread handle.
3354 (start_timer_thread): If the timer thread exited (due to error),
3355 clean up by closing the two handles it used. Duplicate the caller
3356 thread's handle here, so it gets duplicated only once, when
3357 launching the timer thread. Set priority of the timer thread, not
3359 (getitimer): Don't duplicate the caller thread's handle here.
3362 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3364 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3367 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3369 Remove no-longer-used pty_max_bytes variable.
3370 * process.c (pty_max_bytes): Remove; unused.
3371 (send_process): Do not set it.
3373 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3375 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3376 Update dependencies.
3378 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3380 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3381 This follows up on the 2012-09-29 patch that removed indirection
3382 for the 'function' field. Reported by Sergey Vinokurov in
3383 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3385 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3387 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3388 different name, as the MS runtime does not have such a function,
3389 and probably never will.) All callers changed. Ignore DIRFD
3390 value if PATH is an absolute file name, to match Posix spec
3391 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3394 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3396 * xdisp.c (echo_area_display, redisplay_internal):
3397 Omit redundant check whether frame_garbaged is set.
3399 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3401 Use faccessat, not access, when checking file permissions (Bug#12632).
3402 This fixes a bug that has been present in Emacs since its creation.
3403 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3404 which must set some sort of record. (Torek's bug report was against
3405 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3406 same common flaw.) See Torek's Usenet posting
3407 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3408 Posted: Fri Apr 8 14:18:56 1983.
3409 * Makefile.in (LIB_EACCESS): New macro.
3411 * callproc.c (init_callproc):
3412 * charset.c (init_charset):
3413 * fileio.c (check_existing, check_executable, check_writable)
3415 * lread.c (openp, load_path_check):
3416 * process.c (allocate_pty):
3418 Use effective UID when checking permissions, not real UID.
3419 * callproc.c (init_callproc):
3420 * charset.c (init_charset):
3421 * lread.c (load_path_check, init_lread):
3422 Test whether directories are accessible, not merely whether they exist.
3423 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3424 * fileio.c (check_existing, check_executable, check_writable)
3426 Use symbolic names instead of integers for the flags, as they're
3428 (check_writable): New arg AMODE. All uses changed.
3429 Set errno on failure.
3430 (Ffile_readable_p): Use faccessat, not stat + open + close.
3431 (Ffile_writable_p): No need to call check_existing + check_writable.
3432 Just call check_writable and then look at errno. This saves a syscall.
3433 dir should never be nil; replace an unnecessary runtime check
3434 with an eassert. When checking the parent directory of a nonexistent
3435 file, check that the directory is searchable as well as writable, as
3436 we can't create files in unsearchable directories.
3437 (file_directory_p): New function, which uses 'stat' on most platforms
3438 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3439 (Ffile_directory_p, Fset_file_times): Use it.
3440 (file_accessible_directory_p): New function, which uses a single
3441 syscall for efficiency.
3442 (Ffile_accessible_directory_p): Use it.
3443 * xrdb.c (file_p): Use file_directory_p.
3444 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3445 * lread.c (openp): When opening a file, use fstat rather than
3446 stat, as that avoids a permissions race. When not opening a file,
3447 use file_directory_p rather than stat.
3448 (dir_warning): First arg is now a usage string, not a format.
3449 Use errno. All uses changed.
3450 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3451 that merely introduced a race.
3452 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3453 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3454 and similarly for the other O_* flags.
3455 * w32.c (sys_faccessat): Rename from sys_access and switch to
3456 faccessat's API. All uses changed.
3457 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3458 (magic_db): Rename from magic_file_p.
3459 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3460 char *, so that we don't have to test for file existence
3461 separately from opening the file for reading. This removes a race
3462 fixes a permission-checking problem, and simplifies the code.
3464 (file_p): Remove; no longer needed.
3466 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3468 Omit glyphs initialization at startup.
3469 * dispnew.c (glyphs_initialized_initially_p): Remove.
3470 (adjust_frame_glyphs_initially): Likewise. Adjust users.
3471 (Fredraw_frame): Move actual code from here...
3472 (redraw_frame): ...to here. Add eassert. Adjust comment.
3473 (Fredraw_display): Use redraw_frame.
3474 * xdisp.c (clear_garbaged_frames): Likewise.
3476 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3478 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3479 passed to pint2str and pint2hrstr to be at most the size of the
3480 frame's decode_mode_spec_buffer. This avoids crashes with very
3481 large values of FIELD_WIDTH argument to decode_mode_spec.
3484 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3486 Fix a race with verify-visited-file-modtime (Bug#12863).
3487 Since at least 1991 Emacs has ignored an mtime difference of no
3488 more than one second, but my guess is that this was to work around
3489 file system bugs that were fixed long ago. Since the race is
3490 causing problems now, let's remove that code.
3491 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3492 whose time stamp is off by no more than a second. Insist that the
3493 file time stamps match exactly.
3495 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3497 * frame.h (struct frame): Convert external_tool_bar member to
3498 1-bit unsigned bitfield.
3499 * termhooks.h (struct terminal): Remove mouse_moved member since
3500 all users are long dead. Adjust comment on mouse_position_hook.
3502 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3504 Simplify by using FOR_EACH_FRAME here and there.
3505 * frame.c (next_frame, prev_frame, other_visible_frames)
3506 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
3507 * w32term.c (x_window_to_scroll_bar): Likewise.
3508 * window.c (window_list): Likewise.
3509 * xdisp.c (x_consider_frame_title): Likewise.
3510 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
3511 * xfns.c (x_window_to_frame, x_any_window_to_frame)
3512 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
3513 * xmenu.c (menubar_id_to_frame): Likewise.
3514 * xselect.c (frame_for_x_selection): Likewise.
3515 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3516 (x_window_to_menu_bar): Likewise.
3517 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3519 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3521 * data.c (Qdefalias_fset_function): Now static.
3523 Another tweak to vectorlike_header change.
3524 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3525 Remove, and replace all uses with ...
3526 (next_in_free_list, set_next_in_free_list):
3527 New functions, which respect C's aliasing rules better.
3529 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3531 * window.c (list4i): Rename from 'quad'. All uses changed.
3532 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3534 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3536 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3537 warning about mixing declarations and code in ISO C90.
3539 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3541 * window.c (Fsplit_window_internal): Set combination limit of
3542 new parent window to t iff Vwindow_combination_limit is t;
3543 fixing a regression introduced with the change from 2012-09-22.
3544 (Fset_window_combination_limit): Fix doc-string.
3546 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3548 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3549 amount when the scroll margins are too large. When scrolling
3550 backwards in the buffer, give up if cannot reach point or the
3551 scroll margin within a reasonable number of screen lines.
3552 Fixes point position in window under scroll-up/down-aggressively when
3553 point is positioned many lines beyond the window top/bottom.
3556 * ralloc.c (relinquish): If real_morecore fails to return memory
3557 to the system, don't crash; instead, leave the last heap
3558 unchanged and return. (Bug#12774)
3560 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3562 * lisp.h (AUTOLOADP): New macro.
3563 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
3564 * data.c (Ffset): Remove special ad-advice-info handling.
3565 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
3567 (Finteractive_form): Simplify.
3568 (Fquo): Don't insist on having at least 2 arguments.
3569 (Qdefalias_fset_function): New var.
3571 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3573 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

3579 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3581 Fix recently introduced crash on MS-Windows (Bug#12839).
3582 * w32term.h (struct scroll_bar): Use convenient header.
3583 (SCROLL_BAR_VEC_SIZE): Remove.
3584 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3586 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3588 Tweak last vectorlike_header change.
3589 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3590 vectorlike object on the free list. This is introduced to avoid
3591 some (but not all) pointer casting and aliasing problems, see
3592 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3593 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
3595 (xvectype, xvecsize): Use them to examine Lisp_Object values.
3597 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3599 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3600 been removed, so remove them here also.
3602 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3604 * doc.c (Fdocumentation): Handle new property
3605 dynamic-docstring-function to replace the old ad-advice-info.
3607 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
3609 * fns.c (Qeql, hashtest_eq): Now static.

3615 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
3616 * buffer.c (compare_overlays): Use XLI rather than XHASH.
3618 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
3620 Use same hash function for hashfn_profiler as for hash_string etc.
3621 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
3622 * lisp.h (sxhash_combine): New inline function, with the contents
3623 of the old SXHASH_COMBINE.
3624 * profiler.c (hashfn_profiler): Use it, instead of having a
3625 special hash function containing a comparison that always yields 1.
3627 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3629 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3630 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3631 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3634 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3636 * image.c (xpm_make_color_table_h): Fix compiler error because
3637 make_hash_table changed.
3639 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
3641 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3643 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3645 Use ad-hoc comparison function for the profiler's hash-tables.
3646 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3647 (make_log): Use them.
3648 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3649 call Fequal any more.

3658 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
3659 (hash_lookup, hash_remove_from_table): Move assertion checking of
3660 hashfn result here. Check hash-equality before calling cmpfn.

3670 2012-11-08 Eli Zaretskii <eliz@gnu.org>
3672 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
3673 value of w32-scroll-lock-modifier is neither nil nor one of the
3674 known key modifiers. (Bug#12806)
3676 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3678 Shrink struct vectorlike_header to the only size field.
3679 * lisp.h (enum pvec_type): Avoid explicit enum member values.
3681 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
3682 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
3683 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
3684 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
3685 information from the vector header. Adjust comment.

3695 (enum mem_type): Adjust comment.
3696 (NEXT_IN_FREE_LIST): New macro.
3697 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
3698 (Fmake_bool_vector): Likewise.
3699 (struct large_vector): New type to represent allocation unit for
3700 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3701 (large_vectors): Change type to struct large_vector.
3702 (allocate_vector_from_block): Simplify.
3703 (PSEUDOVECTOR_NBYTES): Replace with...
3704 (vector_nbytes): ...new function. Adjust users.

3706 (allocate_vectorlike): Likewise.
3707 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
3708 Add easserts. Adjust XSETPVECTYPESIZE usage.
3709 (allocate_buffer): Use BUFFER_PVEC_INIT.
3710 (live_vector_p): Adjust to match large vector.
3711 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
3712 * buffer.h (struct buffer): Add next member.
3713 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
3715 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
3716 * fns.c (internal_equal): Adjust to match enum pvec_type change.
3717 (copy_hash_table): Adjust to match vector header change.
3718 * lread.c (defsubr): Use XSETPVECTYPE.
3719 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
3720 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
3721 (xvecsize): New command.
3723 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3725 * keyboard.c (event_to_kboard): Do not dereference
3726 frame_or_window field of SELECTION_REQUEST_EVENT
3727 and SELECTION_CLEAR_EVENT events (Bug#12814).
3728 * xterm.h (struct selection_input_event): Adjust comment.
3730 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3732 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3733 such as Scroll Lock, if the respective keys are treated as
3734 function keys, not as modifiers. This avoids destroying non-ASCII
3735 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3737 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3739 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3741 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3743 Restore some duplicate definitions (Bug#12814).
3744 This undoes part of the 2012-11-03 changes. Some people build
3745 with plain -g rather than with -g3, and they need the duplicate
3746 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3747 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3748 Define as macros, as well as as enums or as constants.
3750 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
3752 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
3753 to keypad keys (Bug#12816).
3755 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3757 Minor adjustments of recently-changed frame functions.
3758 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3759 known to be a frame (we're in the FRAMEP branch).
3760 * lisp.h (Qframep): Remove decl. frame.h declares this.
3761 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3762 since they're meant for Lisp fixnum values.
3764 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3766 * window.c (Fwindow_combination_limit): Revert to the only
3767 required argument and adjust docstring as suggested in
3768 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3769 by Martin Rudalics <rudalics@gmx.at>.
3771 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3773 Widely used frame validity and checking functions.
3774 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
3775 * frame.c (decode_live_frame, decode_any_frame): New functions.
3776 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
3777 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
3778 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
3779 (Fframe_pointer_visible_p): Use decode_any_frame.
3780 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
3781 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
3782 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
3783 (Fframe_focus): Likewise. Allow zero number of arguments.
3785 (frame_buffer_list, frame_buffer_predicate): Remove.
3786 * lisp.h (frame_buffer_predicate): Remove prototype.
3787 * buffer.c (Fother_buffer): Use decode_any_frame.
3788 * xdisp.c (Ftool_bar_lines_needed): Likewise.
3789 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3790 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3791 (Fclose_font, Ffont_info): Use decode_live_frame.
3792 * fontset.c (check_fontset_name): Likewise.
3793 * terminal.c (Fframe_terminal): Likewise.
3794 * w32fns.c (check_x_frame): Likewise.
3795 * window.c (Fminibuffer_window, Fwindow_at)
3796 (Fcurrent_window_configuration): Likewise.
3797 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
3798 Likewise. Allow zero number of arguments. Adjust docstring.
3799 * dispnew.c (Fredraw_frame): Likewise.
3800 * xfaces.c (frame_or_selected_frame): Remove.
3801 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3802 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3803 (Fframe_face_alist): Use decode_live_frame.
3804 * xfns.c (check_x_frame): Likewise.
3806 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3808 * window.c (quad): New function.
3809 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3810 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3811 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3812 (Fwindow_line_height): Use it.
3813 (Fwindow_fringes): Use list3.
3814 (Fwindow_scroll_bars): Use list4.
3815 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3816 (Fwindow_combination_limit): Allow zero number of arguments.
3818 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3820 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3822 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3823 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3824 file descriptor 2 for standard error. (Bug#12805)
3826 2012-11-05 Chong Yidong <cyd@gnu.org>
3828 * process.c (wait_reading_process_output): Revert previous change.
3830 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3832 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3833 This removes code that has been obsolete since around 1990.
3834 * callproc.c (Fcall_process):
3836 * process.c (create_process):
3837 * term.c (dissociate_if_controlling_tty):
3838 Assume setsid exists.
3839 * callproc.c (child_setup): Assume setpgid exists and behaves as
3840 per POSIX.1-1988 or later.
3841 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3842 * emacs.c (shut_down_emacs):
3843 * sysdep.c (sys_suspend, init_foreground_group):
3844 Assume getpgrp behaves as per POSIX.1-1998 or later.
3845 * msdos.c (setpgrp): Remove.
3846 (tcgetpgrp, setpgid, setsid): New functions.
3847 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3848 * term.c (no_controlling_tty): Remove; unused.
3849 * w32proc.c (setpgrp): Remove.
3850 (setsid, tcgetpgrp): New functions.
3852 Simplify by assuming __fpending.
3853 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3854 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3855 Do not assume that __fpending's result fits in int.
3857 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3859 Remove EMACS_OUTQSIZE+sleep hack.
3860 * dispnew.c (update_frame_1): Remove hack for terminals slower
3861 than 2400 bps, which throttled Emacs by having it sleep.
3862 This code hasn't worked since at least 2007, when the multi-tty stuff
3863 was added, and anyway those old terminals are long dead.
3864 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3865 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3867 Fix data-loss with --version (Bug#9574).
3868 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3869 as we can't assume that emacs_strerror is initialized, and strerror
3870 is good enough here.
3871 (main): Invoke atexit earlier, to catch earlier instances of
3872 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3874 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3876 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3877 (keyDown): Remap keypad keys to X11 virtual key codes.
3879 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3881 Fix data-loss with --batch (Bug#9574).
3882 * emacs.c: Include <close-stream.h>.
3883 (close_output_streams): New function.
3884 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3885 and handles errors appropriately.
3886 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3889 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3890 The symptom is a diagnostic "GLib-WARNING **: In call to
3891 g_spawn_sync(), exit status of a child process was requested but
3892 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3893 waitpid(), so exit status can't be returned." The diagnostic
3894 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3895 The real bug is a race condition between Emacs and glib: Emacs
3896 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3897 so that glib can't find it. Work around the bug by invoking
3898 waitpid only on subprocesses that Emacs itself creates.
3899 * process.c (create_process, record_child_status_change):
3900 Don't use special value -1 in pid field, as the caller now must
3901 know the pid rather than having the callee infer it.
3902 The inference was sometimes incorrect anyway, due to another race.
3903 (create_process): Set new 'alive' member if child is created.
3904 (process_status_retrieved): New function.
3905 (record_child_status_change): Use it.
3906 Accept negative 1st argument, which means to wait for the
3907 processes that Emacs already knows about. Move special-case code
3908 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3909 processes that have already been waited for, by testing and
3910 clearing new 'alive' member.
3911 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3912 now does this internally.
3913 (handle_child_signal): Let record_child_status_change do all
3914 the work, since we do not want to reap all exited child processes,
3915 only the child processes that Emacs itself created.
3916 * process.h (Lisp_Process): New boolean member 'alive'.
3918 Omit duplicate definitions no longer needed with gcc -g3.
3919 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3920 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3921 Define only as macros. There's no longer any need to also define
3922 these symbols as enums or as constants, since we now assume
3923 gcc -g3 when debugging.
3925 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3927 * lisp.mk: Adjust comments to the fact that term/internal is now
3928 loaded from loadup.el.
3930 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3931 (msdos_fatal_signal): New function.
3932 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3935 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3936 for GCC versions before 4.
3937 (emacs_raise): Define to call msdos_fatal_signal.
3939 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3940 iterator when starting in the middle of a display or overlay
3943 2012-11-03 Chong Yidong <cyd@gnu.org>
3945 * process.c (wait_reading_process_output): Clean up the last
3948 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3950 * process.c (wait_reading_process_output): Avoid a race condition
3951 with SIGIO delivery (Bug#11536).
3953 2012-11-03 Chong Yidong <cyd@gnu.org>
3955 * buffer.c (cursor_type): Untabify docstring.
3957 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3959 * frame.h (struct frame): Drop can_have_scroll_bars member
3960 which is meaningless for a long time. Adjust comments.
3961 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3962 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3964 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3966 * window.c (decode_next_window_args): Update window arg after
3967 calling decode_live_window and so fix crash reported at
3968 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3969 by Juanma Barranquero <lekktu@gmail.com>.
3970 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3971 * font.c (Ffont_at): Likewise.
3973 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3975 * widget.c (resize_cb): New function.
3976 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3977 (EmacsFrameResize): Check if all is up to date before changing frame
3980 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3982 Implement backtrace output for fatal errors on MS-Windows.
3983 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3984 (BACKTRACE_LIMIT_MAX): New macro.
3985 (w32_backtrace): New function.
3986 (emacs_abort): Use w32_backtrace when the user chooses not to
3987 attach a debugger. Update the text of the abort dialog.
3989 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3991 Window-related stuff cleanup here and there.
3992 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3993 Use decode_any_window.
3994 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3995 * xdisp.c (Fformat_mode_line): Likewise.
3996 * font.c (Ffont_at): Use decode_live_window.
3997 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3998 * window.c (decode_next_window_args): Likewise.
3999 (decode_any_window): Remove static.
4000 * window.h (decode_any_window): Add prototype.
4001 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
4002 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
4005 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4007 Remove pad from struct input_event.
4008 * termhooks.h (struct input_event): Remove padding field.
4010 * keyboard.c (event_to_kboard): Simplify because frame_or_window
4011 member is never cons for a long time. Adjust comment.
4012 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
4013 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
4014 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
4015 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
4017 2012-11-01 Eli Zaretskii <eliz@gnu.org>
4019 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
4021 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
4023 Fix crash when using Emacs as commit editor for git (Bug#12697).
4024 * callproc.c (setpgrp): Remove macro, as we now use setpgid
4025 and it is configured in conf_post.h.
4026 (Fcall_process): Don't invoke both setsid and setpgid; the former
4027 is enough, if it exists.
4028 * callproc.c (Fcall_process, child_setup):
4029 * process.c (create_process): Use setpgid.
4030 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
4032 * dispnew.c (init_display): Initialize the foreground group
4033 if we are running a tty display.
4034 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
4035 * lisp.h (init_foreground_group): New decl.
4036 * sysdep.c (inherited_pgroup): New static var.
4037 (init_foreground_group, tcsetpgrp_without_stopping)
4038 (narrow_foreground_group, widen_foreground_group): New functions.
4039 (init_sys_modes): Narrow foreground group.
4040 (reset_sys_modes): Widen foreground group.
4042 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
4044 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
4046 2012-10-31 Martin Rudalics <rudalics@gmx.at>
4048 * minibuf.c (read_minibuf): Restore current buffer since
4049 choose_minibuf_frame calling Fset_frame_selected_window may
4050 change it (Bug#12766).
4052 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
4054 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
4056 2012-10-30 Kenichi Handa <handa@gnu.org>
4058 * font.c (Ffont_at): If WINDOW is specified and it is not
4059 displaying the current buffer, signal an error.
4061 2012-10-29 Daniel Colascione <dancol@dancol.org>
4063 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
4064 In preparation for fixing bug#12739, move these functions from
4067 * coding.h, coding.c: ... to here, and compile them only when
4068 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
4069 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
4071 2012-10-28 Eli Zaretskii <eliz@gnu.org>
4073 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
4074 (timer_loop, getitimer, setitimer): Use it instead of
4075 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
4077 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
4080 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
4082 * nsterm.m (NO_APPDEFINED_DATA): New define.
4083 (last_appdefined_event_data): New variable
4084 (last_appdefined_event): Remove.
4085 (ns_select): Initialize t from last_appdefined_event_data instead
4086 of [last_appdefined_event data1].
4087 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
4088 remove last_appdefined_event (Bug#12698).
4090 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
4092 * frame.c (x_set_font): Catch internal error.
4094 2012-10-27 Eli Zaretskii <eliz@gnu.org>
4096 Avoid overflow in w32 implementation of interval timers.
4097 When possible, for ITIMER_PROF count only times the main thread
4099 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
4100 'volatile ULONGLONG' types. All the other data which was
4101 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
4102 (GetThreadTimes_Proc): New typedef.
4103 (w32_get_timer_time): New function, returns a suitable time value
4105 (timer_loop): Enter critical section when accessing ULONGLONG
4106 values of the itimer_data struct, as these accesses are no longer
4107 atomic. Call 'w32_get_timer_time' instead of 'clock'.
4108 Remove unused variable.
4109 (init_timers): Initialize s_pfn_Get_Thread_Times.
4110 (start_timer_thread): Don't assign itimer->caller_thread here.
4111 (getitimer): Assign itimer->caller_thread here.
4112 (setitimer): Always call getitimer to get the value of ticks_now.
4113 (sys_spawnve): Avoid compiler warning about format mismatch.
4115 2012-10-26 Eli Zaretskii <eliz@gnu.org>
4117 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
4118 mouse movement events if the menu bar is active. This avoids
4119 producing a busy "hour-glass" cursor by Windows if the mouse
4120 pointer is positioned over a tooltip shown for some menu item.
4122 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
4124 Don't assume process IDs fit in int.
4125 * emacs.c (shut_down_emacs) [!DOS_NT]:
4126 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
4127 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
4128 Use pid_t, not int, to store process IDs, as 'int'
4129 is not wide enough on a few platforms (e.g., AIX and IRIX).
4131 2012-10-23 Kenichi Handa <handa@gnu.org>
4133 The following change is to make face-font-rescale-alist work
4134 correctly for non-ASCII fonts.
4136 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
4137 (font_open_for_lface): Handle Vface_font_rescale_alist.
4139 2012-10-23 Chong Yidong <cyd@gnu.org>
4141 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
4143 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
4145 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
4147 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
4149 * xterm.c (x_focus_changed): Check if daemonp when sending focus in

4634 2012-10-08 Daniel Colascione <dancol@dancol.org>
4636 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4637 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
4638 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
4639 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
4640 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
4641 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4642 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4643 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4644 now a supported configuration.
4646 * Makefile.in: consolidate image variables into LIBIMAGE; add
4647 W32_OBJ and W32_LIBS. Compile new files.
4650 (_DebPrint) declare tracing facility for W32 debugging. We need
4651 to unify tracing later.
4653 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4654 unconditional use of W32 Unicode functions. Cygwin runs only on
4655 100% Unicode operating systems.
4657 * cygw32.c: New file. Define Cygwin-specific facilities.
4658 (Fcygwin_convert_path_to_windows)
4659 (Fcygwin_convert_path_from_windows): New user functions for
4660 accessing Cygwin path-munging routines.
4662 * cygw32.h: New file.
4663 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4664 UTF-16LE strings temporarily inside non-Lisp-visible string
4667 (w32_strerror): Just what it says on the tin.
4669 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4670 also run for Cygwin; both systems have the same problem with using
4671 GUI facilities in a forked child. Also call syms_of_cygw32,
4672 syms_of_w32select in correct places.
4674 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4675 needs fork-then-exec for daemon launching.
4677 * font.h: Include frame.h.
4679 * image.c: Use the image library cache machinery only when we're
4680 compiling for native WINDOWSNT; Cygwin can use shared libraries
4681 like any other Unixlike system.
4683 * keyboard.c: Clarify a comment regarding the input loop.
4685 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4686 functions directly instead of trying to detect at runtime that our
4687 host operating system supports them. We make this change for two
4688 reasons: Cygwin lacks support for the multibyte character
4689 conversion functions used by the legacy menu code, and Cygwin
4690 never needs to rely on non-Unicode APIs.
4692 * unexw32.c (hinst): Declare extern.
4694 * w32.c: Change header order;
4695 (w32_strerror): Move to w32fns.c because we need it for
4696 non-WINDOWSNT builds.
4698 * w32.h: Add #error macro to make sure we don't include w32.h for
4699 Cygwin builds. Remove w32select declarations.
4701 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4702 w32fns.c. w32console.c is WINDOWSNT-only.
4704 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4705 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4707 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4708 (w32_major_version, w32_minor_version, w32_build_number)
4709 (os_subtype, sound_type): Define here
4710 (w32_defined_color): Make color parameter const for consistency
4711 with other _defined_color functions.
4712 (w32_createwindow): Unconditionally call w32_init_class instead of
4713 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4714 through the code is complex and unnecessary because class
4715 registration is practically free.
4716 (w32_name_of_message): New EMACSDEBUG-only function.
4717 (Fset_message_beep): Move here
4718 (Fx_open_connection): Require that the display name for Windows be
4719 "w32" for consistency, emacsclient disambiguation, and maybe, one
4720 day, multi-window-system support.
4721 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4722 Cygwin files for W32 GUI facilities, since these clearly don't
4723 expect Cygwin names.
4724 (_DebPrint): Define.
4725 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4726 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4727 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4728 (w32_last_error): Remove.
4730 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4732 * w32heap.c (syspage_mask): Declare here.
4733 (cache_system_info): Remove.
4735 * w32inevt.c (faked_key): Define globally, not statically.
4736 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4737 (w32_console_toggle_lock_key): Move to w32fns.c.
4739 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4741 * w32proc.c (_DebPrint): Move to w32fns.c.
4742 * w32select.c: Include string.h, stdio.h for Cygwin.
4743 * w32select.h: New File.
4745 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4747 (w32_message_fd): New variable. Under Cygwin, holds the file
4748 descriptor the system used to tell us about pending thread
4751 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4752 that prevented compilation under non-WINDOWSNT systems.
4754 (w32_initialize): Open /dev/windows and assign it to
4755 w32_message_fd. Provide w32 feature.
4757 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4758 (WM_EMACS_INPUT_READY): add.
4759 (prepend_msg, w32_message_fd): Declare globally.
4762 (keyboard_handle): Use only when WINDOWSNT.
4763 (notify_msg_ready): New function. Posts a message to the main
4764 thread's message queue under CYGWIN, which wakes up the main
4765 thread from select(2) by making the /dev/windows file descriptor
4766 ready. Under WINDOWSNT, it sets an event the same way the old
4769 (post, prepend_msg): Actually call notify_msg_ready instead of
4770 setting the input event directly.
4772 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4774 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4775 but it still has blocs in it, don't return it to the system,
4776 instead of aborting. (Bug#12402)
4778 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4780 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4782 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4783 MAC_OS_X_VERSION_10_6.
4784 (syms_of_nsterm): Remove comment about Panther and above for
4786 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
4787 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
4788 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4790 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4791 MAC_OS_X_VERSION_10_4.
4793 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4794 MAC_OS_X_VERSION_10_2.
4796 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4798 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4799 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4801 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4802 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4803 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4804 Remove ns_in_resize check.
4805 (ns_clear_frame_area): Remove resize handle code.
4807 * nsfns.m (ns_in_resize): Remove.
4808 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4809 Remove ns_in_resize check.
4811 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4813 Improve sys_siglist detection.
4814 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4815 defined as a macro, as is done in Solaris.
4816 (sys_siglist_entries): New macro.
4817 (save_strsignal): Use it.
4818 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4819 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4821 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4823 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4824 fullscreen/Fullscreen.
4826 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4827 tobar_height is new.
4829 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4830 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4831 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4832 (windowDidResize:): Check for correct window if old style fullscreen.
4833 Capitalize word in comment. Remove incorrect comment.
4834 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4835 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4836 error in drawing background.
4837 (toggleFullScreen:): Remove comment. Rearrange calls.
4838 Set toolbar values to zero, save old height in tobar_height.
4839 Restore tool bar height when leaving fullscreen.
4840 (canBecomeMainWindow): New function.
4842 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4844 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4846 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4848 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4850 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4851 that time stamps of directories could also be changed.
4852 Don't request the too broad GENERIC_WRITE, only the more restrictive
4853 FILE_WRITE_ATTRIBUTES access rights.
4855 * fileio.c (Fset_file_times): Special-case ignoring errors for
4856 directories only on MSDOS, not on MS-Windows.
4858 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4860 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4862 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4864 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4865 see whether CreateFile failed.
4867 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4869 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4870 to avoid similar races.
4871 * keyboard.c (pending_signals): Now bool, not int.
4873 Port timers to OpenBSD, plus check for timer failures.
4874 OpenBSD problem reported by Han Boetes.
4875 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4877 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4878 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4879 like OpenBSD, which has timer_settime but does not declare it.
4880 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4881 whether to use itimerspec-related primitives. All uses of
4882 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4884 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4886 * profiler.c (handle_profiler_signal): Fix a malloc race
4887 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4889 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4891 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4893 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4895 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4896 consistent with the change in return value of 'safe_strsignal'.
4898 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4900 Prefer plain 'static' to 'static inline' (Bug#12541).
4901 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4902 (bidi_set_sor_type, bidi_push_embedding_level)
4903 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
4904 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
4905 (bidi_cache_search, bidi_cache_ensure_space)
4906 (bidi_cache_iterator_state, bidi_cache_find)
4907 (bidi_peek_at_next_level, bidi_set_paragraph_end)
4908 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4909 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4910 Now 'static', not 'static inline'.
4912 Count overruns when profiling; change units to ns.
4913 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4914 Give extra weight to samples after overruns, to attempt to count
4915 the time more accurately.
4916 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4917 the underlying primitives nominally do ns.
4918 (Fprofiler_cpu_start): Document the change. Mention that
4919 the sampling intervals are only approximate.
4921 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4923 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4925 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4926 case for the special 0 coding-system.
4928 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4929 (Fmake_overlay): Remove redundant tests.
4930 (fix_start_end_in_overlays): Remove redundant recentering.
4932 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4934 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4935 Update dependencies.
4937 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4939 Fix a malloc race condition involving strsignal.
4940 A signal can arrive in the middle of a malloc, and Emacs's signal
4941 handler can invoke strsignal, which can invoke malloc, which is
4942 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4943 Fix it by altering the signal handler so that it does not invoke
4945 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4946 * process.c (status_message): Use const pointer, in case strsignal
4947 is #defined to safe_strsignal.
4948 * sysdep.c (sys_siglist, init_signals): Always define and
4949 initialize a substitute sys_siglist if the system does not define
4950 one, even if HAVE_STRSIGNAL.
4951 (safe_strsignal): Rename from strsignal. Always define,
4952 using sys_siglist. Return a const pointer.
4953 * syssignal.h (safe_strsignal): New decl.
4954 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4956 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4958 * w32proc.c (timer_loop): Fix code that waits for timer
4959 expiration, to avoid high CPU usage.
4961 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4963 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4964 (sweep_weak_table): Remove redundant prototypes.
4966 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4968 * emacs.c: Move the inclusion of TERM_HEADER after including
4969 windows.h on WINDOWSNT. This avoids compilation problems with
4972 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4974 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4975 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4976 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4977 as the previous version used 'void *'.
4979 * ralloc.c (ROUNDUP): Fix last change.
4980 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4983 * w32proc.c <disable_itimers>: New static flag.
4984 (init_timers): Initialize it to zero, after creating the critical
4985 sections used by the timer threads.
4986 (term_timers): Set to 1 before deleting the critical sections.
4987 (getitimer, setitimer): If disable_itimers is non-zero, return an
4988 error indication without doing anything. Reported by Fabrice
4989 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4990 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4992 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4995 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4996 term_ntproc after all the other bookkeeping, to get timers working
4997 as long as possible.
4999 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5001 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
5002 Suggested by Juri Linkov in
5003 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
5005 Prefer plain 'static' to 'static inline' (Bug#12541).
5006 With static functions, modern compilers inline pretty well by
5007 themselves; advice from programmers often hurts as much as it helps.
5008 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
5009 this change shrinks the text size of the Emacs executable by 1.1%
5010 without affecting CPU significantly in my benchmark.

5304 (handle_profiler_signal): Rename from sigprof_handler_1,
5305 for consistency with other handlers. Do not check whether
5306 cpu_log is a hash-table if garbage collecting, since it

5309 for consistency with other handlers.
5310 (setup_cpu_timer): New function, with much of what used to be in

5312 Prefer timer_settime if available, and prefer
5313 thread cputime clocks, then process cputime clocks, then
5314 monotonic clocks, to the old realtime clock. Use make_timeval
5315 to round more-correctly when falling back to setitimer.
5316 (Fprofiler_cpu_start): Use it.
5317 (Fprofiler_cpu_stop): Prefer timer_settime if available.

5535 Move pid_t related decls out of lisp.h.
5536 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
5537 (interruptible_wait_for_termination):
5538 Move these decls from lisp.h to syswait.h, since they use pid_t.
5539 Needed on FreeBSD; see Herbert J. Skuhra in
5540 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
5541 * callproc.c: Include syswait.h.
5543 gnutls.c, gtkutil.c: Use bool for boolean.
5544 * gnutls.c (gnutls_global_initialized, init_gnutls_functions)
5545 (emacs_gnutls_handle_error):
5546 * gtkutil.c (xg_check_special_colors, xg_prepare_tooltip)
5547 (xg_hide_tooltip, xg_create_frame_widgets)
5548 (create_dialog, xg_uses_old_file_dialog)

5556 (update_frame_tool_bar, free_frame_tool_bar):
5557 * gtkutil.c, w32term.c, xterm.c (x_wm_set_size_hint):
5558 * nsmenu.m (ns_update_menubar):
5559 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
5560 * xfns.c (Fx_show_tip) [USE_GTK]:
5561 Use bool for boolean.
5562 * gtkutil.c (xg_update_frame_menubar):
5563 * xmenu.c (update_frame_menubar):
5564 Return void, not int, since caller ignores return value.
5565 * gtkutil.c (xg_change_toolbar_position):
5568 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5570 * makefile.w32-in (BLOCKINPUT_H): Remove.

5587 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5589 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5590 fatal_error_backtrace.
5592 * w32proc.c (sys_kill): Undo last change: don't do anything when
5593 invoked to deliver SIGABRT to our own process. This is now
5594 handled by emacs_raise.
5596 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5598 * w32term.c (w32_read_socket): Remove leftover reference to
5599 interrupt_input_pending.
5601 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5603 Do not use SA_NODEFER.
5604 Problem reported by Dani Moncayo in
5605 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5607 * sysdep.c (emacs_abort): Do not reset signal handler.
5608 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5609 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5610 wanted even on POSIXish hosts, and it doesn't work on Windows.
5612 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5614 * xterm.c (x_term_init): Call fixup_locale before and after calling
5615 gtk_init (Bug#12392).
5617 2012-09-23 Chong Yidong <cyd@gnu.org>
5619 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5620 Vdynamic_library_alist.
5622 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5623 (Fgnutls_available_p): Caller changed.
5625 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5626 (Flibxml_parse_xml_region): Likewise.
5628 * dispextern.h (struct image_type): Remove arg from init function.
5630 * image.c (Finit_image_library, lookup_image_type)
5631 (define_image_type): Remove now-unneeded second arg.
5632 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5633 (init_tiff_functions, init_gif_functions, init_svg_functions):
5634 Arglist and w32_delayed_load calling convention changed.
5635 (gs_type): Remove init_gs_functions; there is no such function.
5636 (valid_image_p, make_image): Fix caller to lookup_image_type.
5638 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5640 Simplify and avoid signal-handling races (Bug#12471).
5642 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5643 Avoid recursive loop if there's a fatal error in the function itself.
5644 * atimer.c (pending_atimers):
5645 * blockinput.h: Don't include "atimer.h"; no longer needed.
5646 (interrupt_input_pending): Remove. All uses removed.
5647 pending_signals now counts both atimers and ordinary interrupts.
5648 This is less racy than having three separate pending-signal flags.
5649 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5651 Rename from their upper-case counterparts BLOCK_INPUT,
5652 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5653 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5654 This makes it easier to access volatile variables more accurately.
5655 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5656 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5657 that's more reliable if the code is buggy and sets
5658 interrupt_input_blocked to a negative value. All uses changed.
5659 * atimer.c (deliver_alarm_signal):
5660 Remove. No need to deliver this to the parent; any thread can
5661 handle this signal now. All uses replaced by underlying handler.
5662 * atimer.c (turn_on_atimers):
5663 * dispnew.c (handle_window_change_signal):
5664 * emacs.c (handle_danger_signal):
5665 * keyboard.c (kbd_buffer_get_event):
5666 Don't reestablish signal handler; not needed with sigaction.
5667 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5669 Rework to avoid unnecessary accesses to volatile variables.
5670 (UNBLOCK_INPUT_TO): Now a function.
5671 (totally_unblock_input, unblock_input): New decls.
5672 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5673 (init_data): Remove. Necessary stuff now done in init_signal.
5674 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5675 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5676 (fatal_error_code): Remove; no longer needed.
5677 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5678 it doesn't always backtrace. All uses changed. No need to reset
5679 signal to default, since sigaction and/or die does that for us now.
5680 Use emacs_raise (FOO), not kill (getpid (), FOO).
5681 (main): Check more-accurately whether we're dumping.
5682 Move fatal-error setup to sysdep.c
5683 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5684 * gtkutil.c (xg_get_file_name, xg_get_font):
5685 Remove no-longer-needed signal-mask manipulation.
5686 * keyboard.c, process.c (POLL_FOR_INPUT):
5687 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5688 * keyboard.c (read_avail_input): Remove.
5689 All uses replaced by gobble_input.
5690 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5691 (kbd_buffer_store_event_hold, gobble_input):
5692 (record_asynch_buffer_change) [USABLE_SIGIO]:
5693 (store_user_signal_events):
5694 No need to mess with signal mask.
5695 (gobble_input): If blocking input and there are terminals, simply
5696 set pending_signals to 1 and return. All hooks changed to not
5697 worry about whether input is blocked.
5698 (process_pending_signals): Clear pending_signals before processing
5699 them, in case a signal comes in while we're processing.
5700 By convention callers now test pending_signals before calling us.
5701 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5702 New functions, to support changes to blockinput.h.
5703 (handle_input_available_signal): Now extern.
5704 (reinvoke_input_signal): Remove. All uses replaced by
5706 (quit_count): Now volatile, since a signal handler uses it.
5707 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5708 All callers changed. Block SIGINT only if not already blocked.
5709 Clear sigmask reliably, even if Fsignal returns, which it can.
5710 Omit unnecessary accesses to volatile var.
5711 (quit_throw_to_read_char): No need to restore sigmask.
5712 * keyboard.c (gobble_input, handle_user_signal):
5713 * process.c (wait_reading_process_output):
5714 Call signal-handling code rather than killing ourselves.
5715 * lisp.h: Include <float.h>, for...
5716 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5717 (pending_signals): Now volatile.
5718 (syms_of_data): Now const if IEEE floating point.
5719 (handle_input_available_signal) [USABLE_SIGIO]:
5720 (terminate_due_to_signal, record_child_status_change): New decls.
5721 * process.c (create_process): Avoid disaster if memory is exhausted
5722 while we're processing a vfork, by tightening the critical section
5724 (send_process_frame, process_sent_to, handle_pipe_signal)
5725 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5727 (send_process): No need for setjmp/longjmp any more, since the
5728 SIGPIPE stuff is now gone. Instead, report an error if errno
5730 (record_child_status_change): Now extern. PID and W are now args.
5731 Return void, not bool. All callers changed.
5732 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5733 Remove. All uses removed. This bug should be fixed now in a
5735 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5736 and record the child status change directly. This avoids the
5737 need to futz with the signal mask.
5738 (process_fatal_action): Move here from emacs.c.
5739 (emacs_sigaction_flags): New function, containing
5740 much of what used to be in emacs_sigaction_init.
5741 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5742 caught by emacs, to make races less likely.
5743 (deliver_process_signal): Rename from handle_on_main_thread.
5745 (BACKTRACE_LIMIT_MAX): Now at top level.
5746 (thread_backtrace_buffer, threadback_backtrace_pointers):
5748 (deliver_thread_signal, deliver_fatal_thread_signal):
5749 New functions, for more-accurate delivery of thread-specific signals.
5750 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5751 (deliver_arith_signal): Handle in this thread, not
5752 in the main thread, since it's triggered by this thread.
5753 (maybe_fatal_sig): New function.
5754 (init_signals): New arg DUMPING so that we can be more accurate
5755 about whether we're dumping. Caller changed.
5756 Treat thread-specific signals differently from process-general signals.
5757 Block all signals while handling fatal error; that's safer.
5758 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5760 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5761 Ignore SIGPIPE unless batch.
5762 (emacs_backtrace): Output backtrace for the appropriate thread,
5763 which is not necessarily the main thread.
5764 * syssignal.h: Include <stdbool.h>.
5765 (emacs_raise): New macro.
5766 * xterm.c (x_connection_signal): Remove; no longer needed
5767 now that we use sigaction.
5768 (x_connection_closed): No need to mess with sigmask now.
5769 (x_initialize): No need to reset SIGPIPE handler here, since
5770 init_signals does this for us now.
5772 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5774 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5775 background rect may be larger (Bug#12245).
5777 2012-09-23 Chong Yidong <cyd@gnu.org>
5779 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5781 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5783 * .gdbinit: Just stop at fatal_error_backtrace.
5784 See Stefan Monnier's request in
5785 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5786 Remove no-longer-used query of system type.
5788 2012-09-22 Chong Yidong <cyd@gnu.org>
5790 * search.c (Freplace_match): Doc fix (Bug#12325).
5792 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5794 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5795 (Fline_end_position): Doc fix.
5797 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5799 2012-09-22 Chong Yidong <cyd@gnu.org>
5801 * dispextern.h (struct image_type): Add new slot, storing a type
5802 initialization function.
5804 * image.c (define_image_type): Call the image initializer function
5805 if it is defined. Arguments and return value changed.
5806 (valid_image_p, make_image): Callers changed.
5807 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5808 (gif_type, imagemagick_type, svg_type, gs_type):
5809 Add initialization functions.
5810 (Finit_image_library): Call lookup_image_type.
5811 (CHECK_LIB_AVAILABLE): Macro deleted.
5812 (lookup_image_type): Call define_image_type here, rather than via
5813 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5814 (syms_of_image): Move define_image_type calls for xbm_type and
5815 pbm_type to lookup_image_type.
5817 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5819 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5820 'idle_timers' from here ...
5821 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5822 lists, to avoid infloops when the timer does something stupid,
5823 like reinvoke itself with the same or smaller time-out.
5826 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5828 * window.c (Fsplit_window_internal): Handle only Qt value of
5829 Vwindow_combination_limit separately.
5830 (Qtemp_buffer_resize): New symbol.
5831 (Vwindow_combination_limit): New default value.
5834 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5836 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5837 the new overlay string. (Bug#10159)
5839 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5841 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5842 or that fprintf is async-signal-safe. POSIX doesn't require
5845 2012-09-22 Chong Yidong <cyd@gnu.org>
5847 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5850 2012-09-22 Kenichi Handa <handa@gnu.org>
5852 * composite.c (composition_reseat_it): Handle the case that a
5853 grapheme cluster is not covered by a single font (Bug#12352).
5855 2012-09-21 Chong Yidong <cyd@gnu.org>
5857 * image.c (define_image_type): Avoid adding duplicate types to
5858 image_types (Bug#12463). Suggested by Jörg Walter.
5860 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5862 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5863 (print_load_command_name): Add case LC_DATA_IN_CODE.
5864 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5866 2012-09-21 Glenn Morris <rgm@gnu.org>
5868 * eval.c (Frun_hook_with_args_until_success)
5869 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5871 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5873 * fileio.c (Ffile_selinux_context): Only call freecon when
5874 lgetfilecon succeeded.
5875 (Fset_file_selinux_context): Likewise. (Bug#12444)
5877 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5879 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5880 reordering, locate the cursor by calling set_cursor_from_row; if
5881 that fails, clear the desired glyph matrix before returning a
5882 failure indication to the caller. Fixes leaving garbled display
5883 when fast scrolling with a down-key. (Bug#12403)
5884 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5885 scrolling through multibyte text.
5887 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5889 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5890 calling mark_vectorlike since that's the one that marks the window.
5891 (mark_discard_killed_buffers): Mark the final cdr.
5892 * window.h (struct window): Move prev/next_buffers to the
5893 non-standard fields.
5894 * window.c (make_window): Initialize prev/next_buffers manually.
5896 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5898 Omit unused arg EXPECTED from socket hooks.
5899 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5900 * nsterm.m (ns_term_init):
5901 * termhooks.h (struct terminal.read_socket_hook):
5902 * w32inevt.c (w32_console_read_socket):
5903 * w32term.c (w32_read_socket):
5904 * xterm.c (XTread_socket):
5905 Omit unused arg EXPECTED. All callers changed.
5906 (store_user_signal_events): Return void, not int, since callers no
5907 longer care about the return value. All uses changed.
5909 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5911 * w32gui.h (XParseGeometry): Do not declare.
5913 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5915 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5916 Ignore 'expected'. See Eli Zaretskii in
5917 <http://bugs.gnu.org/12471#8> (last line).
5919 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5920 (XParseGeometry): Now static. Substitute extremal values for
5921 values that are out of range.
5923 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5925 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5927 * nsfns.m (XParseGeometry): Remove.
5928 (Fx_create_frame): Call x_set_offset to correctly interpret
5929 top_pos in geometry.
5931 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5932 (Fx_parse_geometry): If there is a space in string, call
5933 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5935 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5937 * search.c (scan_buffer): Use character positions in calls to
5938 region_cache_forward and region_cache_backward, not byte
5939 positions. (Bug#12196)
5941 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5942 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5944 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5945 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5946 emacs_blocked_malloc, now deleted.
5948 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5950 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5951 The workaround was for improving performance on Solaris 2.4, but
5952 is getting in the way now. Emacs will still work if someone is
5953 still running Solaris 2.4 in a museum somewhere; Sun dropped
5954 support for Solaris 2.4 in 2003.
5955 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5956 * process.c (create_process) [HAVE_WORKING_VFORK]:
5957 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5958 since Emacs no longer uses vfork on that platform.
5960 2012-09-17 Glenn Morris <rgm@gnu.org>
5962 * emacs.c: Use COPYRIGHT.

5966 Remove configure's --without-sync-input option (Bug#12450).
5967 When auditing signal-handling in preparation for cleaning it up,
5968 I found that SYNC_INPUT has race conditions and would be a real
5969 pain to fix. Since it's an undocumented and deprecated
5970 configure-time option, now seems like a good time to remove it.
5971 Also see <http://bugs.gnu.org/11080#16>.
5972 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5973 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5974 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5975 (malloc_hysteresis):
5976 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5977 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5978 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5979 (dont_register_blocks, bytes_used_when_reconsidered)
5980 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5981 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5982 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5983 Remove. All uses removed.
5984 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5985 implementation, one that depends on whether the new macro
5986 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5988 * atimer.c (run_timers, handle_alarm_signal):
5989 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5990 (handle_async_input, process_pending_signals)
5991 (handle_input_available_signal, init_keyboard):
5992 * nsterm.m (ns_read_socket):
5993 * process.c (wait_reading_process_output):
5994 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5995 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5997 * xterm.c (XTread_socket):
5999 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
6000 * eval.c (handling_signal): Remove. All uses removed.
6001 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
6002 All uses replaced with the SYNC_INPUT version.
6003 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
6005 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6008 * font.c (Ffont_shape_gstring): Remove unused local.
6010 2012-09-16 Glenn Morris <rgm@gnu.org>
6012 * Makefile.in (clean): No longer run nextstep's clean.
6014 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
6016 (ns-app): Move here from ns.mk, and simplify.
6017 (clean): Simplify nextstep entry.
6018 * ns.mk: Remove file.
6020 2012-09-17 Kenichi Handa <handa@gnu.org>
6022 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
6023 not covert the last few charactes.
6025 2012-09-16 Kenichi Handa <handa@gnu.org>
6027 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
6028 here, but just check the validity of glyphs in the glyph-string.
6030 2012-09-16 Martin Rudalics <rudalics@gmx.at>
6032 * window.c (Fwindow_parameter, Fset_window_parameter):
6033 Accept any window as argument (Bug#12452).
6035 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
6037 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
6038 to ns_term_init to avoid memory leak.
6040 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
6041 explicit retain/release.
6042 (ns_term_init): Only allow one display. Initialize outerpool and
6045 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6047 Port _setjmp fix to POSIXish hosts as well as Microsoft.
6048 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
6049 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
6050 the Microsoft problem in a different way, by altering ../nt/config.nt.
6052 2012-09-15 Eli Zaretskii <eliz@gnu.org>
6067 * w16select.c: Remove inclusion of setjmp.h, as it is now included
6068 by lisp.h. This completes removal of setjmp.h inclusion
6069 erroneously announced in the previous commit. (Bug#12446)
6071 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
6074 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
6075 not defined as a macro. The latter happens on MS-Windows.
6078 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6080 Port better to POSIX hosts lacking _setjmp (Bug#12446).
6081 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
6082 Some instances of '#include <setjmp.h>' removed, if the
6083 only reason for the instance was because "lisp.h" was included.
6084 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
6085 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
6086 and _longjmp with the new symbols. Emacs already uses _setjmp if
6087 available, so this change affects only POSIXish hosts that have
6088 sigsetjmp but not _setjmp, such as some versions of Solaris and
6089 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
6090 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
6091 (png_load_body) [HAVE_PNG]:
6092 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
6093 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
6094 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
6095 since PNG requires jmp_buf. This is the only exception to the
6096 general rule that we now use sys_setjmp and sys_longjmp.
6097 This exception is OK since this code does not change the signal
6098 mask or longjmp out of a signal handler.
6100 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
6102 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6103 Include "syssignal.h", for 'main_thread'.
6105 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
6107 Avoid out-of-range marker position (Bug#12426).
6108 * insdel.c (replace_range, replace_range_2):
6109 Adjust markers before overlays, as suggested by comments.
6110 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
6111 Remove redundant check before calling offset_intervals.
6113 2012-09-14 Martin Rudalics <rudalics@gmx.at>
6115 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
6116 current buffer (Bug#12387).
6118 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
6120 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
6122 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6124 Use a more backwards-compatible timer format (Bug#12430).
6125 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
6126 vector element, not from the 4th, since PSECS is now at the end.
6127 (Fcurrent_idle_time): Doc fix.
6129 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
6131 Function to mark objects and remove killed buffers at once.
6132 * alloc.c (discard_killed_buffers): Rename to ...
6133 (mark_discard_killed buffers) ... new name. Add marking
6134 of remaining objects. Fix comment. Adjust users.
6135 (mark_object): Do not touch frame buffer lists here.
6136 * frame.c (delete_frame): Reset frame buffer lists here.
6138 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6140 Better workaround for GNOME bug when --enable-gcc-warnings.
6141 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
6142 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
6143 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
6145 Simplify SIGIO usage (Bug#12408).
6146 The code that dealt with SIGIO was crufty and confusing, e.g., it
6147 played tricks like "#undef SIGIO" but these tricks were not used
6148 consistently. Simplify mostly by not #undeffing standard symbols,
6149 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
6150 or not as we please) rather than "defined SIGIO" (standard symbol
6151 that we probably shouldn't #undef).
6152 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
6153 Modules that need it can include it.
6154 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
6155 * dispextern.h (ignore_sigio): New decl.
6156 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
6157 unconditionally, since it's now a no-op if !USABLE_SIGIO.
6158 * emacs.c (shut_down_emacs):
6159 * keyboard.c (kbd_buffer_store_event_hold):
6160 Use ignore_sigio rather than invoking 'signal' directly.
6161 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
6163 (FIONREAD, SIGIO): Do not #undef.
6164 (tty_read_avail_input): Use #error rather than a syntax error.
6165 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
6166 for I_PIPE, used by SETUP_SLAVE_PTY.
6167 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
6168 * sysdep.c (croak): Remove; no longer needed. This bit of
6169 temporary code, with Fred N. Fish's comment that it's temporary,
6170 has been in Emacs since at least 1992!
6171 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
6172 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
6173 * syssignal.h (croak): Remove decl.
6174 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
6175 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
6176 now that we're termios-only.
6177 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
6178 * term.c (dissociate_if_controlling_tty): Use #error rather than
6181 Work around GCC and GNOME bugs when --enable-gcc-warnings.
6182 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
6183 to work around GNOME bug 683906.
6184 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
6185 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
6186 This works around GCC bug 54561.
6188 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6190 More fixes for 'volatile' and setjmp/longjmp.
6191 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
6192 * image.c (struct png_load_context) [HAVE_PNG]: New type.
6193 (png_load_body) [HAVE_PNG]:
6194 (jpeg_load_body) [HAVE_JPEG]:
6195 New function, with most of the old parent function's body.
6196 (png_load) [HAVE_PNG]:
6197 (jpeg_load) [HAVE_JPEG]:
6198 Invoke the new function, to avoid longjmp munging our locals.
6199 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
6200 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
6201 longjmp is passed 2, as the C standard doesn't guarantee this.
6202 Instead, store the failure code into mgr->failure_code.
6204 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6206 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
6207 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
6208 (syms_of_keyboard): Remove support for unread-command-char.
6210 2012-09-12 Eli Zaretskii <eliz@gnu.org>
6212 * w32proc.c (sys_kill): If PID is our process ID and the signal is
6213 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
6214 violation. (Bug#12426)
6216 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6218 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
6220 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6222 * eval.c: Add `inhibit-debugger'.
6223 (Qinhibit_debugger): New symbol.
6224 (call_debugger): Bind it instead of Qdebug_on_error.
6225 (maybe_call_debugger): Test Vinhibit_debugger.
6226 (syms_of_eval): Define inhibit-debugger.
6227 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6228 (syms_of_xdisp): Remove inhibit-debug-on-message.
6230 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6232 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6233 If a nonvolatile local variable is written before a _longjmp to
6234 the frame containing the variable, and is read after the _longjmp,
6235 the value read is indeterminate. Some local variables of type
6236 'struct handler' and 'struct catchtag' are used in this way, so
6237 mark each of their slots as volatile if the slot can be set before
6238 _longjmp and read afterwards.
6239 * lisp.h (struct handler): var and chosen_clause are now volatile.
6240 (struct catchtag): val, next, and pdlcount are now volatile.
6242 * bidi.c (bidi_push_it, bidi_pop_it):
6243 * fns.c (copy_hash_table):
6244 * image.c (define_image_type):
6245 * keyboard.c (kbd_buffer_store_event_hold):
6246 * process.c (Fprocess_send_eof):
6247 * xfaces.c (x_create_gc) [HAVE_NS]:
6248 * xgselect.c (xg_select):
6249 Prefer assignment to memcpy when either will do.
6251 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6252 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6253 time an item is removed. No need to mark this function 'inline';
6254 the compiler knows better than we do.
6256 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6258 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6259 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6260 to change_frame_size (Bug#12388).
6261 (windowDidResize:): Pass YES to updateFrameSize.
6263 * nsterm.h: Add delay parameter to updateFrameSize.
6265 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6267 Discard killed buffers from deleted window and frame objects.
6268 This reduces an amount of references to killed buffers and
6269 helps GC to reclaim them faster.
6270 * alloc.c (discard_killed_buffers): New function.
6271 (mark_object): Use it for deleted windows and frames.
6272 (mark_object): If symbol's value is set up for a killed buffer
6273 or deleted frame, restore its global binding.
6274 * data.c (swap_in_global_binding): Add GC notice.
6275 (swap_in_symval_forwarding): Use convenient set_blv_where.
6276 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6277 * window.h: ... to here.
6279 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6281 Convenient macro to check whether the buffer is live.
6282 * buffer.h (BUFFER_LIVE_P): New macro.
6283 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6284 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6286 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6288 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6289 composition cases (Bug#12364).
6291 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6292 overhang of succeeding glyphs overlapping box cursor.
6294 * w32term.c (x_draw_glyph_string): Likewise.
6296 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6298 Simplify, document, and port floating-point (Bug#12381).
6299 The porting part of this patch fixes bugs on non-IEEE platforms
6300 with frexp, ldexp, logb.
6301 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6303 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6304 support, by removing commented-out code and briefly listing the
6305 C89 functions excluded. The commented-out stuff was confusing
6306 maintenance, e.g., we thought we needed cbrt but it was commented out.
6307 (logb): Remove decl; no longer needed.
6308 (isfinite): New macro, if not already supplied.
6309 (isnan): Don't replace any existing macro.
6310 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6311 are present on all C89 platforms.
6312 (Ffrexp): Do not special-case zero, as frexp does the right thing
6314 (Flogb): Do not use logb, as it doesn't have the desired meaning
6315 on hosts that use non-base-2 floating point. Instead, stick with
6316 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6317 frexp, to avoid getting an unspecified result.
6319 * xdisp.c (Qinhibit_debug_on_message): Now static.
6321 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6323 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6324 NSBezierPath (Bug#12131).
6326 2012-09-10 Chong Yidong <cyd@gnu.org>
6328 * fns.c (Fdelq, Fdelete): Doc fix.
6330 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6332 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6333 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6335 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6337 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6338 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6341 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6343 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6344 left fringe if the window has a left margin. This avoids leaving
6345 traces of the cursor because its leftmost pixel is not drawn over.
6347 * dispnew.c (update_window_line): When the left margin area of a
6348 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6349 that screen line. (Bug#12277)
6351 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6353 Assume C89 or later for math functions (Bug#12381).
6354 This simplifies the code, and makes it a bit smaller and faster,
6355 and (most important) makes it easier to clean up signal handling
6356 since we can stop worring about floating-point exceptions in
6357 library code. That was a problem before C89, but the problem
6358 went away many years ago on all practical Emacs targets.
6359 * data.c, image.c, lread.c, print.c:
6360 Don't include <math.h>; no longer needed.
6361 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6362 might be autoconfigured, as that never happens.
6364 * doprnt.c (DBL_MAX_10_EXP):
6365 * print.c (DBL_DIG):
6366 Remove. C89 or later always defines these.
6367 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6368 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6369 (arith_error, domain_error, domain_error2):
6370 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6371 no longer needed -- we simply return what C returns. All uses removed.
6372 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6374 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6375 Remove. All uses expanded, as these macros are no longer used
6376 more than once and are now more trouble than they're worth.
6377 (Ftan): Use tan, not sin / cos.
6378 (Flogb): Assume C89 frexp.
6379 (fmod_float): Assume C89 fmod.
6380 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6381 (init_floatfns): Remove. All uses removed.
6383 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6385 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6386 compositeToPoint for OSX < 10.6 (Bug#12390).
6388 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6390 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6391 This produces more-accurate results.
6393 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6395 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6396 changes (Bug#12088).
6398 2012-09-08 Chong Yidong <cyd@gnu.org>
6400 * syntax.c (Fstring_to_syntax): Doc fix.
6402 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6404 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6405 in the internal border.
6406 (x_set_window_size): Remove static variables and their usage.
6407 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6408 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6409 Remove fringe/internal border adjustment (Bug#11052).
6410 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6411 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6412 (ns_fix_rect_ibw): Remove.
6413 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6414 (ns_dumpglyphs_box_or_relief): Ditto.
6415 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6417 (ns_dumpglyphs_image): Ditto.
6418 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6420 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6421 their usage. Add fringe_extended_p and its use as in other terms.
6422 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6423 scroll bar was removed.
6424 (updateFrameSize): New function.
6425 (windowDidResize): Move code to updateFrameSize and call it.
6427 * nsterm.h (EmacsView): Add updateFrameSize.
6429 2012-09-07 Chong Yidong <cyd@gnu.org>
6431 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6433 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6435 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6437 More signal-handler cleanup (Bug#12327).
6438 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6439 Problem introduced when merging patches. Noted by Eli Zaretskii in
6440 <http://bugs.gnu.org/12327#67>.
6441 * floatfns.c: Comment fix.
6442 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6443 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6444 and anyway the declaration is harmless even if SIGDANGER is not defined.
6445 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6446 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6447 source files not surprisingly expected syssignal.h to define, or
6448 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6449 Include <sys/ioctl.h>, for FIONREAD.
6450 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6451 This eliminates a problem whereby other files mysteriously had
6452 to include "syssignal.h" before including "systty.h" if they
6453 wanted to use "#ifdef SIGIO".
6455 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6457 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6459 * w32.c (sigemptyset): Empty the set.
6460 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6462 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6464 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6466 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6467 (mark_object): Likewise for frame objects.
6469 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6471 * syssignal.h (handle_on_main_thread): Always declare,
6472 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6473 This ports to platforms without HAVE_PTHREAD.
6475 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6477 Signal-handler cleanup (Bug#12327).
6478 Emacs's signal handlers were written in the old 4.2BSD style with
6479 sigblock and sigmask and so forth, and this led to some
6480 inefficiencies and confusion. Rewrite these to use
6481 pthread_sigmask etc. without copying signal sets around. Also,
6482 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6483 'signal', and instead use functions that do not attempt to take
6484 over the system name space. This patch causes Emacs's text
6485 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6486 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6487 Do not include <signal.h> or "syssignal.h", as these
6488 modules do not use signals.
6489 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6490 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6491 Do not include <signal.h>, as "syssignal.h" does that for us now.
6492 * atimer.c (sigmask_atimers): New function.
6493 (block_atimers, unblock_atimers): New functions,
6494 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6496 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6497 no longer needed here.
6498 * emacs.c (main): Inspect existing signal handler with sigaction,
6499 so that there's no need to block and unblock SIGHUP.
6500 * sysdep.c (struct save_signal): New member 'action', replacing
6501 old member 'handler'.
6502 (save_signal_handlers, restore_signal_handlers):
6503 Use sigaction instead of 'signal' to save and restore.
6504 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6505 New function. All users of 'signal' modified to use set_sighandler
6506 if they're writeonly, and to use sys_signal if they're read+write.
6507 (emacs_sigaction_init, forwarded_signal): New functions.
6508 (sys_signal): Remove. All uses replaced by calls to sigaction
6509 and emacs_sigaction_init, or by direct calls to 'signal'.
6510 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6511 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6512 all uses replaced by pthread_sigmask etc. calls.
6513 * syssignal.h: Include <signal.h>.
6514 (emacs_sigaction_init, forwarded_signal): New decls.
6515 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6516 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6517 (sigmask, sys_sigmask): Remove; no longer needed.
6518 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6519 (sigblock, sigunblock, sigfree):
6520 (sigsetmask) [!defined sigsetmask]:
6521 Remove. All uses replaced by pthread_sigmask.
6522 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6523 no longer need to be replaced, and its typical old uses
6524 are now done via emacs_sigaction_init and sigaction.
6525 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6526 (sys_sigdel): Remove; unused.
6527 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6529 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6531 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6532 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6534 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6536 Explicitly mark buffer_defaults and buffer_local_symbols.
6537 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6538 mark_local_symbols here.
6539 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6540 since special buffers aren't marked here any more.
6541 (allocate_buffer): Chain new buffer with all_buffers here...
6542 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6544 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6545 (syms_of_buffer): Remove staticpro of the above.
6546 (init_buffer_once): Set names for buffer_defaults and
6547 buffer_local_symbols.
6549 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6551 Use bool for booleans in font-related modules.
6552 * font.c (font_intern_prop, font_style_to_value)
6553 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6554 (generate_otf_features, font_check_otf_features, font_check_otf)
6555 (font_match_p, font_list_entities, font_at):
6556 * fontset.c (fontset_id_valid_p, reorder_font_vector
6557 (fontset_find_font, Fset_fontset_font)
6558 (face_suitable_for_char_p) [0]:
6559 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6560 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6561 (m17n_flt_initialized, ftfont_shape_by_flt):
6562 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6563 * nsfont.m (nsfont_draw):
6564 * w32font.c (w32font_draw):
6565 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6566 Use bool for booleans.
6567 * font.h: Adjust to above API changes.
6568 (struct font, struct font_driver, struct font_driver_list):
6569 Use bool for booleans.
6570 (struct font): Remove useless member encoding_type.
6572 * fontset.c, xftfont.c: Omit unnecessary static decls.
6574 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6576 * alloc.c (mark_object): Revert window marking code
6577 since it's unsafe for the Fset_window_configuration.
6579 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6581 Fix race conditions with signal handlers and errno (Bug#12327).
6582 Be more systematic about preserving errno whenever a signal
6583 handler returns, even if it's not in the main thread. Do this by
6584 renaming signal handlers to distinguish between signal delivery
6585 and signal handling. All uses changed.
6586 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6587 * data.c (deliver_arith_signal): Rename from arith_error.
6588 * dispnew.c (deliver_window_change_signal): Rename from
6589 window_change_signal.
6590 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6591 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6592 * keyboard.c (deliver_input_available_signal): Rename from
6593 input_available_signal.
6594 (deliver_user_signal): Rename from handle_user_signal.
6595 (deliver_interrupt_signal): Rename from interrupt_signal.
6596 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6597 (deliver_child_signal): Rename from sigchld_handler.
6598 * atimer.c (handle_alarm_signal):
6599 * data.c (handle_arith_signal):
6600 * dispnew.c (handle_window_change_signal):
6601 * emacs.c (handle_fatal_signal, handle_danger_signal):
6602 * keyboard.c (handle_input_available_signal):
6603 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6604 * process.c (handle_pipe_signal, handle_child_signal):
6605 New functions, with the actual signal-handling code taken from the
6606 original respective signal handlers, sans the sporadic attempts to
6607 preserve errno, since that's now done by handle_on_main_thread.
6608 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6609 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6610 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6612 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6613 Move initialization of main_thread to sysdep.c's init_signals.
6614 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6615 our usage, and simplifies the mainline code.
6616 (record_child_status_change): New static function, as a helper
6617 for handle_child_signal, and with most of the old child handler's
6619 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6620 (handle_child_signal): Use the above.
6621 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6622 Moved here from emacs.c.
6623 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6624 code moved here from emacs.c's main function.
6625 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6626 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6627 This lets callers save and restore errno properly.
6629 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6631 Remove redundant or unused things here and there.
6632 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6633 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6634 * editfns.c (Fcompare_buffer_substrings): Likewise.
6635 * frame.h (struct terminal, struct font_driver_list):
6636 Remove redundant declarations.
6637 * window.h (Qleft, Qright): Likewise.
6639 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6641 Do not mark objects from deleted buffers, windows and frames.
6642 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6643 (mark_object): Likewise for windows and frames.
6645 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6647 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6648 buffer_defaults and buffer_local_symbols as valid objects.
6649 Return special value to denote them.
6651 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6653 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6654 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6655 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6656 (file_name_absolute_p, Fsubstitute_in_file_name):
6657 (check_executable, check_writable, Ffile_accessible_directory_p)
6658 (Fset_file_selinux_context, Fdefault_file_modes)
6659 (Finsert_file_contents, choose_write_coding_system)
6660 (Fwrite_region, build_annotations, a_write, e_write)
6662 * filelock.c (boot_time_initialized, get_boot_time)
6663 (get_boot_time_1, lock_file_1, within_one_second):
6664 * floatfns.c (in_float):
6665 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6666 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6667 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6668 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6669 * window.c (compare_window_configurations):
6670 Use bool for booleans.
6671 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6672 (Fdefault_file_modes): Now mode_t, not int, for modes.
6673 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6674 (internal_delete_file): Now returns void, not a (boolean) int,
6675 since nobody was looking at the return value.
6676 * lisp.h, window.h: Adjust to above API changes.
6678 * xdisp.c (set_message): Simplify and reindent last change.
6680 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6682 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6684 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6686 * eval.c (call_debugger): Make the function non-static so that we
6687 can call it from set_message.
6689 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6690 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6692 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6694 Give more-useful info on a fatal error (Bug#12328).
6695 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6696 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6697 of doing the work ourselves.
6698 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6699 do most of the work.
6700 (fatal_error_backtrace): New function, taken from the guts
6701 of the old fatal_error_signal, but with a new option to output
6703 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6704 info about the signal than just its number.
6705 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6706 * sysdep.c: Include <execinfo.h>
6707 (emacs_backtrace): New function, taken partly from the previous
6708 code of the 'die' function.
6709 (emacs_abort): Call fatal_error_backtrace rather than abort.
6711 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6713 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6714 eager (load-time) macro-expansion.
6715 * lisp.mk (lisp): Add macroexp.
6717 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6719 Simplify redefinition of 'abort' (Bug#12316).
6720 Do not try to redefine the 'abort' function. Instead, redo
6721 the code so that it calls 'emacs_abort' rather than 'abort'.
6722 This removes the need for the NO_ABORT configure-time macro
6723 and makes it easier to change the abort code to do a backtrace.
6724 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6725 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6726 Remove; sysdep.c's emacs_abort now takes its place.
6727 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6728 'abort' changed to use 'emacs_abort'.
6729 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6730 (abort) [!defined abort]: Rename to ...
6731 (emacs_abort): ... new name.
6732 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6733 the place of the old 'abort' in emacs.c.
6734 * w32.c, w32fns.c (abort): Do not #undef.
6735 * w32.c (emacs_abort): Rename from w32_abort.
6737 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6739 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6740 offsets[j].dv, since the y axis of the screen coordinates points
6741 down, while the y axis of the font definition coordinates points
6742 up. This fixes display of Arabic diacritics such as KASRA and
6743 KASRATAN. (Bug#11860)
6745 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6747 Be more systematic about _setjmp vs setjmp.
6748 * alloc.c (test_setjmp, mark_stack):
6749 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
6750 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
6751 (png_load, my_error_exit, jpeg_load):
6752 * process.c (send_process_trap, send_process):
6753 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6754 The underscored versions are up to 30x faster on some hosts.
6755 Formerly, the code used setjmp+longjmp sometimes and
6756 _setjmp+_longjmp at other times, with no particular reason to
6757 prefer setjmp+longjmp.
6759 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
6761 Fix minor problem found by static checking.
6762 * buffer.c (Fdelete_all_overlays): Return nil.
6764 2012-09-03 Martin Rudalics <rudalics@gmx.at>
6766 * buffer.c (Fdelete_all_overlays): New function.
6768 2012-09-03 Chong Yidong <cyd@gnu.org>
6770 * gtkutil.c: Add extern decl for Qxft.
6772 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
6774 * emacs.c, eval.c: Use bool for boolean.
6775 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
6776 (malloc_using_checking) [DOUG_LEA_MALLOC]:
6777 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
6778 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
6779 (main, decode_env_path, Fdaemon_initialized):
6780 * eval.c (call_debugger, Finteractive_p, interactive_p):
6781 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
6782 (maybe_call_debugger, Fbacktrace):
6783 * process.c (read_process_output, exec_sentinel):
6784 Use bool for booleans.
6785 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
6786 All callers changed.
6787 * eval.c (interactive_p): Omit always-true boolean argument
6788 EXCLUDE_SUBRS_P. All callers changed.
6789 * dispextern.h, lisp.h: Reflect above API changes.
6790 * firstfile.c (dummy): Use the address of 'main', whose signature
6791 won't change, instead of the address of 'initialize', whose
6792 signature just changed from int to bool.
6793 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
6794 * msdos.c (fatal_error_in_progress): ... from here.
6795 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6797 (redisplay_internal, unwind_redisplay): Simply clear
6798 REDISPLAYING_P when unwinding, instead of saving its previous,
6799 always-false value and then restoring it.
6801 Clean up some extern decls.
6802 Mostly, this hoists extern decls out of .c files and into .h files.
6803 That way, we're more likely to catch errors if the interfaces change.
6804 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6805 declare xg_mark_data.
6806 * dispextern.h (x_frame_parm_handlers):
6808 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
6809 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
6810 (Qultra_bold, Qoblique, Qitalic):
6811 Move extern decl here from .c file.
6812 * alloc.c (xg_mark_data) [USE_GTK]:
6814 * eval.c (Qlexical_binding):
6815 * fns.c (time) [!HAVE_UNISTD_H]:
6816 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
6817 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):
6818 * image.c (Vlibrary_cache, QCloaded_from) [HAVE_NTGUI]:
6819 * lread.c (Qinternal_interpreter_environment):
6820 * minibuf.c (Qbuffer):
6821 * process.c (QCfamily, QCfilter):
6822 * widget.c (free_frame_faces):
6823 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
6824 * xfont.c (x_clear_errors):
6825 * xterm.c (x_frame_parm_handlers):
6826 Remove now-redundant extern decls.
6827 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
6828 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
6830 * xfaces.c: Remove unnecessary static decls.
6831 * xterm.c (updating_frame): Remove decl of nonexistent object.
6833 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
6834 when building globals.h, as the objects that are not built on
6835 this host are not needed to compile C files on this host.

6891 offset adjustment values separately for each cluster. (Bug#11860)
6893 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6894 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6895 about implicit conversions from integer to pointer.
6897 2012-09-01 Daniel Colascione <dancol@dancol.org>

6953 window system declarations.
6955 * frame.h: Move common functions here: set_frame_menubar,
6956 x_set_window_size, x_sync, x_get_focus_frame,
6957 x_set_mouse_position, x_set_mouse_pixel_position,
6958 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6988 the frames which are reachable from Vframe_list.
6989 * term.c (mark_ttys): Remove.
6990 (init_tty): Safely initialize 'top_frame' slot with Qnil.

7014 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
7015 for GCC 4.7.1 x86-64.
7017 2012-08-30 Glenn Morris <rgm@gnu.org>
7019 * lread.c (init_lread): For out-of-tree builds, only add the
7020 source directory's site-lisp dir to the load-path if it exists,
7021 consistent with in-tree builds. (Bug#12302)
7023 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

7042 Handle click on close button as quit.
7044 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
7045 Add window_closed and button_values. Add void as return value for
7046 add(Button|String|Split). addButton takes int instead of Lisp_Object.
7047 Add process_dialog as new member.

7253 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
7254 are all boolean, so make them single-bit bitfields.
7256 * lisp.h (ASET): Remove attempt to detect side effects.
7257 It was meant to be temporary and it often doesn't work,
7258 because when IDX has side effects the behavior of IDX==IDX
7259 is undefined. See Stefan Monnier in
7260 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
7262 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)

7270 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7271 as that's faster and simpler than static storage. Don't bother
7272 with the g_main_context_query overhead if g_main_context_pending
7273 says no events are pending.
7274 (gfds, gfds_size): Remove these static vars.
7275 (xgselect_initialize): Remove; no longer needed.
7276 All uses and decls removed.

7288 2012-08-25 Eli Zaretskii <eliz@gnu.org>
7290 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
7292 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7294 On assertion failure, print backtrace if available.
7295 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
7296 (die) [ENABLE_CHECKING]: Print a backtrace if available.
7297 * Makefile.in (LIB_EXECINFO): New macro.
7300 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
7301 * bytecode.c (exec_byte_code):
7302 * callint.c (check_mark, Fcall_interactively):
7303 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
7304 (getenv_internal, sync_process_alive, call_process_exited):
7305 * lisp.h (USE_SAFE_ALLOCA):
7306 Use bool for booleans, instead of int.
7307 * lisp.h, process.h: Adjust prototypes to match above changes.
7308 * callint.c (Fcall_interactively): Don't assume the mark's
7309 offset fits in 'int'.
7311 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7313 * buffer.c, buffer.h: Use bool for boolean.
7314 * buffer.c (reset_buffer_local_variables)
7315 (buffer_lisp_local_variables, Fset_buffer_modified_p)
7316 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
7317 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
7318 (overlay_touches_p, overlay_strings, Foverlay_put)
7319 (report_overlay_modification, call_overlay_mod_hooks):
7320 (mmap_enlarge, mmap_set_vars):
7321 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7322 Use bool for booleans, instead of int.
7323 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7324 since the 1-or-0 return value is always ignored anyway.
7325 (mmap_initialized_p):
7326 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7327 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7329 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7331 * bidi.c: Use bool for boolean.
7332 This is a bit more readable, and makes the text segment of bidi.o
7333 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7334 Presumably it's faster too.
7335 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
7337 (bidi_cache_find_level_change, bidi_cache_iterator_state)
7338 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
7339 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
7340 (bidi_explicit_dir_char, bidi_level_of_next_char)
7341 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7342 Use bool for booleans, instead of int.
7343 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7344 (bidi_unshelve_cache): Adjust decls to match code.
7346 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7348 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7351 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7353 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7354 * atimer.h: Include <stdbool.h>.
7356 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7358 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7359 compile time tests instead of run time tests on systems that do
7361 (FRAME_MAC_P): Remove leftover from deleted code.
7362 * frame.c (syms_of_frame): Remove leftover from deleted code.
7364 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>

7368 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7370 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7371 Otherwise, the compiler complains about (A?B:C) where B is void
7372 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7373 (fontset_add): Return void, for FONTSET_ADD.
7375 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7377 * alloc.c: Use bool for booleans.
7378 (gc_in_progress, abort_on_gc)
7379 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7380 (dont_register_blocks) [GC_MALLOC_CHECK]:
7381 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
7382 (check_string_bytes, make_specified_string, memory_full)
7383 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
7384 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7385 (mark_stack, valid_pointer_p, make_pure_string)
7386 (Fgarbage_collect, survives_gc_p, gc_sweep):
7387 Use bool for booleans, instead of int.
7388 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7389 Remove unused local.
7390 * alloc.c (PURE_POINTER_P):
7391 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7392 * editfns.c (Fformat):
7393 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7395 * fns.c (sweep_weak_table):
7396 * lisp.h (suppress_checking, push_message, survives_gc_p)
7397 (make_pure_string, gc_in_progress, abort_on_gc):
7398 * lread.c (readchar, read1):
7399 * print.c (Fprin1_to_string):
7400 * xdisp.c (push_message):
7401 Use bool for booleans affected directly or indirectly by
7404 Make recently-introduced setters macros.
7405 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7406 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7407 (set_fontset_default, set_fontset_fallback): Rename from their
7408 upper-case counterparts, and make them functions rather than macros.
7409 This is more consistent with the other recently-introduced setters.
7410 These don't need to be inline, since they're local.
7412 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7414 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7415 the loop (Bug#12247).
7417 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7419 * lisp.h (vcopy): Use memcpy rather than our own loop.
7420 This fixes a performance regression introduced by the recent
7421 addition of vcopy. This means 'vcopy' will need to be modified
7422 for a copying collector, but that's OK. Also, tighten the
7423 checking in the assertion.
7425 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7427 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7428 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7429 non-base glyph for the width of the base character, according to
7430 what x_draw_composite_glyph_string_foreground expects.
7431 Generate WADJUST value according to composition_gstring_width's
7432 expectations, to produce correct width of the composed character.
7433 Reverse the sign of the DU offset produced by ScriptPlace.
7435 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7437 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7439 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7441 Avoid direct writes to contents member of struct Lisp_Vector.
7442 * lisp.h (vcopy): New function to copy data into vector.
7443 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7444 * fns.c (Ffillarray): Use ASET.
7445 * keyboard.c (timer_check_2): Use AREF and ASET.
7446 (append_tool_bar_item, Frecent_keys): Use vcopy.
7447 * lread.c (read_vector): Use ASET.
7448 * msdos.c (Frecent_doskeys): Use vcopy.
7449 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7450 (Finternal_merge_in_global_face): Use ASET and vcopy.

7456 the position of its buffer's point.
7457 (Fset_window_point): For the selected window always go in its
7458 buffer to the specified position.
7460 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7462 Setter macros for fontsets.
7463 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7464 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7465 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7468 2012-08-20 Glenn Morris <rgm@gnu.org>
7470 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7471 Don't assume that `ln -f' works.
7473 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7475 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
7476 and later about non-assignments with no effect. See discussion at
7477 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
7480 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7482 Inline setter functions for Lisp_Objects slots of struct specbinding.
7483 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
7486 2012-08-20 Martin Rudalics <rudalics@gmx.at>
7488 * window.c (select_window): Always make selected window's buffer
7491 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7493 Use AREF and ASET for docstrings of category tables.
7494 * category.h (CATEGORY_DOCSTRING): Use AREF.
7495 (SET_CATEGORY_DOCSTRING): Use ASET.
7496 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
7498 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7500 Inline setter functions for hash table members.
7501 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
7502 (set_hash_hash, set_hash_index): Rename with _slot suffix.
7503 (set_hash_key_and_value, set_hash_index, set_hash_next)
7504 (set_hash_hash): New functions.
7505 * charset.c, fns.c: Adjust users.
7507 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7509 Inline getter and setter functions for per-buffer values.
7510 * buffer.h (per_buffer_default, set_per_buffer_default)
7511 (per_buffer_value, set_per_buffer_value): New functions.
7512 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
7513 * buffer.c, data.c: Adjust users.
7515 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
7517 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
7519 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7521 Rely on <config.h> + <unistd.h> to declare 'environ',
7522 as gnulib does this if the system doesn't.
7523 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7524 Remove declaration. MS-Windows declares it on stdlib.h which is
7525 included by conf_post.h.
7526 * emacs.c (environ) [DOUG_LEA_MALLOC]:
7527 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
7528 * vm-limit.c: Include <unistd.h>, for 'environ'.
7530 * unexaix.c, unexcoff.c: Include "mem-limits.h".
7531 (start_of_data): Remove decl; mem-limits.h provides it.
7533 * xdisp.c (handle_invisible_prop): Make it a bit faster
7534 and avoid a gcc -Wmaybe-uninitialized diagnostic.
7536 2012-08-19 Chong Yidong <cyd@gnu.org>
7538 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
7541 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
7543 * .gdbinit: Use call instead of set when calling a function in the
7546 * data.c (set_internal): Don't use set_blv_found.
7547 (Fkill_local_variable): Likewise.
7549 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
7551 * nsfont.m (ns_ascii_average_width): Ensure the string
7552 ascii_printable is initialized with a null-terminated character
7553 array. Otherwise, it can contain undesired extra characters.
7555 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7557 port new setting code to Sun C 5.8 2005/10/13
7558 * chartab.c, lisp.h (char_table_set, char_table_set_range):
7559 Return void, not Lisp_Object. Otherwise, the compiler
7560 complains about (A?B:C) where B is void and C is Lisp_Object
7561 when compiling CHAR_TABLE_SET, due to the recent change to
7562 the API of sub_char_table_set_contents.
7564 2012-08-18 Chong Yidong <cyd@gnu.org>
7566 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
7567 for the string case (Bug#3874).
7569 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7571 * buffer.h (BSET): Remove (Bug#12215).

8394 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
8395 * w32.c (init_environment): Change the default values of many
8396 environment variables in dflt_envvars[] to NULL, to avoid pushing
8397 them into environment when they were not already defined.
8398 Remove the code that deletes site-lisp subdirectories from the default
8399 value of EMACSLOADPATH, as it is no longer needed.
8400 (check_windows_init_file): Now external, not static.
8401 Use Vload_path as is, without adding anything, as this function is now
8402 called when Vload_path is already set up.
8404 * w32.h (check_windows_init_file): Add prototype.
8406 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

8449 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
8450 Remove unnecessary pointer casts.
8451 * alloc.c (record_xmalloc): New function.
8452 * lisp.h (record_xmalloc): New decl.
8453 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8454 more like a function. This is because the pointer cast is not
8455 needed. All uses changed.
8456 * print.c (print_string, print_error_message): Avoid length recalc.
8458 Improve fix for macroexp crash with debugging (Bug#12118).
8459 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
8460 ARRAY_MARK_FLAG when checking subscripts, because ASET is
8461 not supposed to be invoked from the garbage collector.

8463 (gc_aset): New function, which is like ASET but can be
8464 used in the garbage collector.

8493 with addition of handling of symlinks and support for 'lstat'.
8494 If possible, get file's attributes and security information by
8495 handle, not by name. Produce S_IFLNK bit for symlinks, when
8496 called from 'lstat'.
8497 (stat, lstat): New functions, call 'stat_worker'.
8498 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8499 symlinks when the underlying filesystem supports them.
8501 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
8503 Fix macroexp crash on Windows with debugging (Bug#12118).
8504 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8505 checking subscripts; problem introduced with the recent
8506 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8507 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8508 since it's used in non-static inline functions now.
8510 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
8511 Don't assume buffer size fits in 'int'. Remove unused local.

8531 * composite.c (COMPOSITE_INLINE):
8532 * dispnew.c (DISPEXTERN_INLINE):
8533 * sysdep.c (SYSTIME_INLINE):
8534 Define to EXTERN_INLINE, so that the corresponding functions
8535 are compiled into code.
8536 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
8537 (INLINE_HEADER_END): New macros.
8538 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

8558 hard-coding the path separator.
8560 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
8562 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
8563 This how ASET and AREF are supposed to work, and makes
8564 it easier to think about future improvements. See
8565 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
8566 * charset.h (set_charset_attr): New function.

9052 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
9054 Fix export of symbols to GDB (Bug#12036).
9055 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
9056 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
9057 emacs.c, as this is a more-suitable home. Had this been done earlier
9058 the fix for 12036 would have avoided some of the problems noted in
9059 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
9060 would have been more obvious.
9061 * emacs.c: Do not include <verify.h>; no longer needed.
9062 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
9063 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
9064 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9065 Remove; now done in lisp.h.
9066 * lisp.h (PUBLISH_TO_GDB): New macro.
9067 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
9068 (DATA_SEG_BITS): Use it.
9069 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
9070 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
9071 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
9072 not be usable in #if. This simplifies things.
9074 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
9076 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
9078 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

9081 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
9082 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
9083 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
9084 Adjust to changes in lisp.h and emacs.c, by using
9085 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
9086 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
9087 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
9088 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
9089 instead of gdb_valbits.
9090 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
9091 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
9092 instead of gdb_array_mark_flag.
9093 (xboolvector): Get size from $->size, not $->header.size.
9094 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
9095 (xreload, hook-run, hookpost-run): Remove.
9096 * emacs.c: Include <verify.h>.
9097 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
9098 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
9100 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
9101 (gdb_USE_LSB_TAG): New enum constants.
9102 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9103 Also define these as enum constants, so they're visible to GDB.
9104 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
9105 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
9106 as constants, so they're visible to GDB.
9107 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
9108 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
9109 Now enum constants, not macros, so they're visible to GDB.
9110 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
9111 more convenient now. All uses changed.
9112 (VALMASK) [USE_LSB_TAG]: Also define in this case.
9113 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
9115 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
9117 Explicitly free restriction data that are not needed anymore.

9120 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
9122 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
9123 add argument, tune behavior, and adjust all callers.
9125 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
9127 Use typedef for EMACS_INT, EMACS_UINT.
9128 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
9129 than macros. This simplifies debugging in the usual case, since
9130 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
9131 and it allows expressions involving EMACS_INT casts.
9132 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
9134 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

9144 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
9146 Adjust buffer text indirection counters at the end of Fkill_buffer.
9147 * buffer.c (Fkill_buffer): Adjust indirection counters when the
9148 buffer is definitely dead. This should really fix an issue reported
9149 by Christoph Scholtes again. (Bug#12007).
9150 (init_buffer_once): Initialize indirection counters of
9151 buffer_defaults and buffer_local_symbols (for sanity and safety).
9153 2012-07-24 Eli Zaretskii <eliz@gnu.org>
9155 * xdisp.c (init_iterator): Don't compute dimensions of truncation
9156 and continuation glyphs on tooltip frames, leave them at zero.
9157 Avoids continued lines in tooltips. (Bug#11832)
9159 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>

9184 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9186 Swap buffer text indirection counters in Fbuffer_swap_text.
9187 * buffer.c (Fbuffer_swap_text): Swap indirections too.
9188 This avoids crash reported by Christoph Scholtes at
9189 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
9191 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
9193 * nsmenu.m (Popdown_data): New struct.

9216 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
9218 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
9219 as it's limited by the amount of memory, not by INT_MAX.
9221 2012-07-21 Eli Zaretskii <eliz@gnu.org>
9223 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
9224 in special-event-map. See the discussion at

9374 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9376 * eval.c (Fdefvar): Don't check constants since we only set the var if
9377 it's not yet defined anyway (bug#11904).
9379 * lisp.h (last_undo_boundary): Declare new var.
9380 * keyboard.c (command_loop_1): Set it.
9381 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
9382 were auto-added by the command loop (bug#11774).

9951 with functions, typedefs and enums, making the code easier to debug.
9952 The functional style also makes code easier to read and maintain.
9953 * systime.h: Include <sys/time.h> on all hosts, not just if
9954 WINDOWSNT, since 'struct timeval' is needed in general.
9955 (EMACS_TIME): Now a typedef, not a macro.
9956 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
9958 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
9959 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
9960 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
9961 (EMACS_TIME_LE): Now functions, not macros.
9962 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
9963 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
9964 which are not functions. All uses rewritten to use:
9965 (make_emacs_time): New function.
9966 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
9967 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
9968 not functions. All uses rewritten to use the following, respectively:
9969 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
9970 (add_emacs_time, sub_emacs_time): New functions.
9971 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
9972 * fileio.c (Fcopy_file):
9973 * xterm.c (XTflash): Get the current time closer to when it's used.
9974 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.
9976 * bytecode.c (targets): Suppress -Woverride-init warnings.
9978 Simplify by avoiding confusing use of strncpy etc.
9979 * doc.c (Fsnarf_documentation):
9980 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
9981 * frame.c (Fmake_terminal_frame):
9982 * gtkutil.c (get_utf8_string):
9984 * nsmenu.m (ns_update_menubar):
9985 * regex.c (regerror):
9986 Prefer memcpy to strncpy and strncat when either will do.
9987 * fileio.c (Fsubstitute_in_file_name):
9988 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
9989 (menu_separator_name_p):
9990 * nsmenu.m (ns_update_menubar):
9991 Prefer memcmp to strncmp when either will do.
9992 * nsterm.m: Include <ftoastr.h>.
9994 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9995 Prefer snprintf to strncpy.
9996 * nsterm.m (ns_term_init):
9997 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9998 * nsterm.m (ns_term_init):
9999 Avoid the need for strncpy, by using build_string or
10000 make_unibyte_string directly. Use dtoastr, not snprintf.
10001 * process.c (Fmake_network_process): Diagnose service names that
10002 are too long, rather than silently truncating them or creating
10003 non-null-terminated names.
10004 (Fnetwork_interface_info): Likewise, for interface names.
10005 * sysdep.c (system_process_attributes) [GNU_LINUX]:
10006 Prefer sprintf to strncat.
10007 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
10008 Prefer vsnprintf to vsprintf + strncpy.
10010 2012-07-10 Glenn Morris <rgm@gnu.org>
10012 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
10013 Clarify fallback case.
10015 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10017 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
10018 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
10019 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
10020 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
10021 where argument type is known to be a Lisp_Cons.
10023 2012-07-10 Tom Tromey <tromey@redhat.com>
10025 * bytecode.c (BYTE_CODE_THREADED): New macro.
10026 (BYTE_CODES): New macro. Replaces all old byte-code defines.
10027 (enum byte_code_op): New type.
10028 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
10029 (exec_byte_code): Use them. Use token threading when applicable.
10031 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10033 Optimize pure C strings initialization.
10034 * lisp.h (make_pure_string): Fix prototype.
10035 (build_pure_c_string): New function, defined as static inline. This
10036 provides a better opportunity to optimize away calls to strlen when
10037 the function is called with compile-time constant argument.
10038 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
10039 argument, adjust users accordingly. Use build_pure_c_string where
10041 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
10042 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
10043 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
10045 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10047 Avoid calls to strlen in miscellaneous functions.
10048 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
10049 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
10050 * lread.c (openp): Likewise.
10052 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10054 Avoid calls to strlen in path processing functions.
10055 * fileio.c (file_name_as_directory): Add comment. Change to add
10056 srclen argument and return the length of result. Adjust users
10058 (directory_file_name): Fix comment. Change to add srclen argument,
10059 swap 1st and 2nd arguments to obey the common convention.
10060 Adjust users accordingly.
10061 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
10063 2012-07-10 Glenn Morris <rgm@gnu.org>
10065 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
10066 Move PENDING_OUTPUT_COUNT definition to configure.
10068 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
10069 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
10070 * s/gnu.h (DATA_START): Move definitions to configure.
10072 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
10073 We include usg5-4-common.h, which defines them both.
10075 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
10076 O_RDONLY already includes it).
10078 Stop ns builds setting the EMACSLOADPATH environment variable.
10079 * nsterm.m (ns_load_path): Rename from ns_init_paths.
10080 Now it does not set EMACSLOADPATH, just returns the load-path string.
10081 * nsterm.h: Update accordingly.
10082 * lread.c [HAVE_NS]: Include nsterm.h.
10083 (init_lread) [HAVE_NS]: Use ns_load_path.
10084 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
10086 2012-07-09 Glenn Morris <rgm@gnu.org>
10088 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
10089 since the included bsd-common.h does so.
10091 Stop ns builds setting the EMACSPATH environment variable.
10092 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
10093 (ns_init_paths): Do not set EMACSPATH.
10094 * nsterm.h (ns_exec_path): Add it.
10095 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
10098 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
10100 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
10102 * process.c (wait_reading_process_output): 'waitchannels' was unset
10103 when read_kbd || !NILP (wait_for_cell); fix this.
10105 Add GCC-style 'const' attribute to functions that can use it.
10106 * character.h (char_resolve_modifier_mask):
10107 * keyboard.h (make_ctrl_char):
10108 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
10109 (init_character_once, next_almost_prime, init_fns, init_image)
10110 (flush_pending_output, init_sound):
10111 * mem-limits.h (start_of_data):
10112 * menu.h (finish_menu_items):

10117 Add decls with ATTRIBUTE_CONST.
10119 Minor improvements to make_formatted_string.
10120 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
10121 where int is good enough, as vsprintf returns an int.
10122 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
10124 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10126 Use make_formatted_string to avoid double length calculation.
10127 * lisp.h (make_formatted_string): New prototype.
10128 * alloc.c (make_formatted_string): New function.
10129 * buffer.c (Fgenerate_new_buffer_name): Use it.

10134 (x_report_frame_params): Likewise.
10135 * image.c (gs_load): Likewise.
10136 * minibuf.c (get_minibuffer): Likewise.
10137 * msdos.c (dos_set_window_size): Likewise.
10138 * process.c (make_process): Likewise.
10139 * xdisp.c (ensure_echo_area_buffers): Likewise.
10140 * xsettings.c (apply_xft_settings): Likewise.
10142 2012-07-09 Glenn Morris <rgm@gnu.org>
10144 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
10145 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
10146 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.

10148 * callproc.c [HAVE_NS]: Include nsterm.h.
10149 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
10151 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10153 Move marker debugging code under MARKER_DEBUG.
10154 * marker.c (MARKER_DEBUG): Move marker debugging code under
10155 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
10156 for bootstrap with --enable-checking (~3x slowdown reported
10157 by Juanma Barranquero <lekktu@gmail.com>).
10158 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
10160 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
10162 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
10163 See <http://bugs.gnu.org/11825#29>.
10165 2012-07-08 Eli Zaretskii <eliz@gnu.org>
10167 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
10168 has no font, use the frame's font. (Bug#11813)
10169 (display_line): Add commentary about displaying truncation glyphs
10171 (produce_special_glyphs): Move here from term.c.
10173 * term.c (produce_special_glyphs): Move to xdisp.c.
10175 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
10178 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
10180 * xdisp.c (display_line): Avoid warning about implicit declaration
10183 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
10185 * lisp.h: Remove empty conditional.
10187 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10189 * lread.c (load_path_check): Now static.
10191 Fix some minor --with-ns problems found by static checking.
10192 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
10193 (x_set_font) [!HAVE_X_WINDOWS]:
10194 * image.c (xpm_load_image) [HAVE_NS]:
10195 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
10196 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
10197 Remove unused local.
10198 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
10199 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
10200 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
10201 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
10202 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
10203 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
10204 Fix pointer signedness problem.
10205 * xfaces.c (FRAME_X_FONT_TABLE):
10206 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
10208 2012-07-07 Glenn Morris <rgm@gnu.org>
10210 * lread.c (load_path_check): New function, split from init_lread.
10211 (init_lread): Reorganize. Motivation:
10212 If EMACSLOADPATH is set, check/warn about that rather than the
10213 defaults, which we are not going to use. Hence we can remove
10214 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
10215 Don't warn if site-lisp directories are missing.
10216 If not installed, start from a blank load-path, since
10217 PATH_LOADSEARCH refers to the eventual installation directories.
10219 2012-07-07 Eli Zaretskii <eliz@gnu.org>
10221 Support truncation and continuation glyphs on GUI frames, when
10222 fringes are disabled. (Bug#11832)
10223 * xdisp.c (init_iterator): Get dimensions of truncation and
10224 continuation glyphs even if on GUI frames.
10225 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10226 or both, are absent.
10227 (start_display, move_it_in_display_line_to): Handle the case of a
10228 GUI frame without a fringe to display continuation or truncation
10230 (insert_left_trunc_glyphs): Support GUI frames: make sure
10231 truncation glyphs overwrite enough glyphs from the current line to
10232 have sufficient space in pixels.
10233 (display_line): Support truncation and continuation glyphs on GUI
10234 frames. If some spare pixels are left on the line after inserting
10235 the truncation glyphs, fill that space with a stretch glyph of a
10236 suitably computed width.
10238 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10239 produce_glyphs, to support GUI sessions.
10241 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10243 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10245 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10247 Do not require float-time's arg to fit in time_t (Bug#11825).
10248 This works better on hosts where time_t is unsigned, and where
10249 float-time is applied to the (negative) difference between two times.
10250 * editfns.c (decode_time_components): Last arg is now double *,
10251 not int *, and means to store all the result as a double, without
10252 worrying about whether the seconds part fits in time_t.
10253 All callers changed.
10254 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10255 All callers changed.
10256 (Ffloat_time): Do not fail merely because the specified time falls
10257 outside of time_t range.
10259 2012-07-07 Glenn Morris <rgm@gnu.org>
10261 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
10262 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
10263 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
10265 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
10267 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
10268 Update dependencies.
10270 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
10272 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10274 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
10275 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
10276 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
10277 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
10278 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
10279 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
10281 * xfont.c (compare_font_names): Redo to omit the need for casts.
10283 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
10285 * xfns.c (Fx_change_window_property): Doc fix.
10286 * w32fns.c (Fx_change_window_property): Doc fix.
10288 * w32fns.c (Fx_window_property): Accept the same arguments as the
10289 X Windows version. Doc fix.
10290 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
10292 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10293 Eli Zaretskii <eliz@gnu.org>
10295 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10296 Windows-specific code from nt/config.nt moved here.
10297 Obsolete settings removed.
10299 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10301 * process.c: Avoid unnecessary calls to gettime.
10302 (wait_reading_process_output): Don't get the time of day
10303 when gobbling data immediately and not waiting, as there's no need
10304 for it in that case. This removes a FIXME.
10306 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10308 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10309 is defined (Bug#11768).
10311 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10313 Fix marker debugging code.
10314 * marker.c (byte_char_debug_check): Do not perform the check
10315 if buffer is not multibyte.
10316 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10317 Call byte_char_debug_check with correct arguments.
10319 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10321 Compile marker debugging code only if ENABLE_CHECKING is defined.
10322 * marker.c (byte_char_debug_check, count_markers):
10323 Use only if ENABLE_CHECKING is defined.
10324 (byte_debug_flag): Remove.
10325 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10326 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
10328 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10330 Avoid code repetition in marker-related functions.
10331 * marker.c (attach_marker): New function.
10332 (Fset_marker, set_marker_restricted, set_marker_both)
10333 (set_marker_restricted_both): Use it.
10334 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
10335 Consistently rename charno to charpos.
10336 (marker_position): Add eassert.
10337 (marker_byte_position): Convert to eassert.
10339 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10341 Simplify list operations in unchain_overlay and unchain_marker.
10342 * buffer.c (unchain_overlay): Simplify. Add comment.
10343 * marker.c (unchain_marker): Simplify. Fix comments.
10345 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10347 Introduce fast path for the widely used marker operation.
10348 * alloc.c (build_marker): New function.
10349 * lisp.h (build_marker): New prototype.
10350 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
10351 * composite.c (autocmp_chars): Likewise.
10352 * editfns.c (buildmark): Remove.
10353 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
10354 (save_restriction_save): Use build_marker.
10355 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
10356 * window.c (save_window_save): Likewise.
10358 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10360 Do not use Fdelete_overlay in delete_all_overlays
10361 to avoid redundant calls to unchain_overlay.
10362 * buffer.c (drop_overlay): New function.
10363 (delete_all_overlays, Fdelete_overlay): Use it.
10364 * minibuf.c (get_minibuffer): Fix comment.
10366 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10368 Port to OpenBSD 5.1 amd64.
10369 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10370 This is needed for OpenBSD, and should be harmless on all BSD systems.
10371 Also, include <sys/sysctl.h>, as it should be available on all
10372 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10373 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10374 use p_pid member, not kp_proc.pid.
10376 2012-07-06 Glenn Morris <rgm@gnu.org>
10378 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10380 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10382 More xmalloc and related cleanup.
10383 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

10391 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
10393 Omit needless casts involving void * pointers and allocation.
10394 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10395 as the former is more robust if P's type is changed.
10396 Prefer xzalloc to xmalloc + memset 0.
10397 Simplify malloc-or-realloc to realloc.
10398 Don't worry about xmalloc returning a null pointer.
10399 Prefer xstrdup to xmalloc + strcpy.
10400 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
10402 * keyboard.c (apply_modifiers_uncached): Prefer local array to
10403 alloca of a constant.
10405 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10407 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10408 hscroll is larger than the line width. Fixes long and futile
10409 looping inside extend_face_to_end_of_line (on a TTY) producing
10410 glyphs that are not needed and thrown away.
10412 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10414 * marker.c (set_marker_restricted_both): Simplify by using
10417 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10419 * editfns.c (region_limit): Simplify by using clip_to_bounds.
10421 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
10423 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
10424 not defined (Bug#11768).
10425 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
10426 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)

10434 (xg_tool_item_stale_p): Call is_box_type.
10435 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10436 with default display (Bug#11768).
10438 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10440 * xdisp.c (window_hscroll_limited): New function.
10441 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10442 coordinates when window's hscroll is set to insanely large
10443 values. (Bug#11857)
10445 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

10508 * fileio.c (time_error_value): Check the right error number.
10509 Problem reported by Troels Nielsen in
10510 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10512 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10514 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10515 This should be fixed in a better way; see Eli Zaretskii in
10516 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10517 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10519 * fileio.c (time_error_value): Rename from special_mtime.
10520 The old name's problems were noted by Eli Zaretskii in
10521 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10523 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10524 This variable's comment says Emacs needs at least one GDB-visible
10525 symbol of type enum pvec_type, to work around GDB problems.
10526 The symbol's value doesn't matter.
10528 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10529 that causes compilation to fail on pre-C99 compilers.
10531 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10533 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
10534 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
10536 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10538 * buffer.c (init_buffer_once): Fix initialization of
10539 headers for buffer_defaults and buffer_local_symbols.
10540 Reported by Juanma Barranquero <lekktu@gmail.com>.
10542 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
10544 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
10545 * lisp.h (enum pvec_type): Use fewer bits.
10546 (PSEUDOVECTOR_SIZE_BITS): New constant.
10547 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
10548 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
10549 change in pvec_type.
10550 (PSEUDOVECTOR_TYPEP): New macro.
10551 (TYPED_PSEUDOVECTORP): Use it.
10552 * fns.c (internal_equal): Adapt code to extract pvectype.
10553 * emacs.c (gdb_pvec_type): Update type.
10554 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
10555 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
10556 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
10557 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10558 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10559 abusing vector->header.next.nbytes.
10560 (live_vector_p): Use PVEC_TYPE.
10561 (mark_object): Adapt code to extract pvectype. Use switch.
10563 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10565 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10566 Tighten new eassert a bit.
10568 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10570 Fix compilation with --enable-gcc-warnings and -O1
10571 optimization level.
10572 * doprnt.c (doprnt): Change type of tem to int, initialize
10573 to avoid compiler warning. Add eassert.
10574 * search.c (simple_search): Initialize match_byte to avoid
10575 compiler warning. Add eassert.
10577 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10579 Avoid weird behavior with large horizontal scrolls.
10580 Without this change, for example, large hscroll values would
10581 mess up Emacs's display on Fedora 15 x86, presumably due to
10582 overflows in int calculations in the display code.
10583 Also, if buffers had long lines, Emacs would freeze.
10584 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10585 (set_window_hscroll): New function, containing the old guts of
10586 Fset_window_hscroll. Return the clipped value.
10587 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10588 This avoids the need to check against PTRDIFF_MAX.
10590 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10592 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10594 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10596 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10598 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10599 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10600 since GCC 4.4.6 issues a bogus warning for them.
10602 Fix bugs in file timestamp newness comparisons.
10603 * fileio.c (Ffile_newer_than_file_p):
10604 * lread.c (Fload): Use full timestamp resolution of files,
10605 not just the 1-second resolution, so that files that are only
10606 slightly newer still count as newer.
10607 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10608 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10610 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10612 * fileio.c: Improve handling of file time marker. (Bug#11852)
10613 (special_mtime): New function.
10614 (Finsert_file_contents, Fverify_visited_file_modtime):
10615 Use it to set special mtime values consistently.
10617 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10619 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10620 marker for non-existing file. (Bug#11852)
10622 2012-07-03 Glenn Morris <rgm@gnu.org>
10624 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10625 and did not make it into globals.h).
10627 2012-07-03 Tom Tromey <tromey@redhat.com>
10629 * window.c (Fset_window_margins, Fset_window_fringes)
10630 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
10631 * textprop.c (Fprevious_property_change): No longer static.
10632 * syntax.c (Fsyntax_table_p): No longer static.
10633 * process.c (Fget_process, Fprocess_datagram_address): No longer

10653 * dispextern.h: Remove EXFUNs.
10654 * intervals.h: Remove EXFUNs.
10655 * fontset.h: Remove EXFUN.
10656 * font.h: Remove EXFUNs.
10657 * dosfns.c (system_process_attributes): Remove EXFUN.
10658 * keymap.h: Remove EXFUNs.
10659 * lisp.h: Remove EXFUNs.
10660 * w32term.h: Remove EXFUNs.
10661 * window.h: Remove EXFUNs.
10662 * xsettings.h: Remove EXFUN.
10663 * xterm.h: Remove EXFUN.
10665 2012-07-03 Glenn Morris <rgm@gnu.org>
10667 * lisp.h (Frandom): Make it visible to C.
10668 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
10669 buffer for invisible buffers. (Bug#1229)
10671 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10673 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
10674 values which aren't power of 2.
10675 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10676 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
10679 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
10681 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
10683 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10685 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10687 * alloc.c (allocate_vector_block): Remove redundant
10688 calls to mallopt if DOUG_LEA_MALLOC is defined.
10689 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10690 avoid calls to mallopt if zero_vector is returned.
10692 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10694 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10695 is enabled, avoid dereferencing NULL current_sblock if
10698 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10700 Cleanup basic buffer management.
10701 * buffer.h (struct buffer): Change layout to use generic vector
10702 marking code. Fix some comments. Change type of 'clip_changed'
10703 to bitfield. Remove unused #ifndef old.
10704 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10705 (GET_OVERLAYS_AT): Fix indentation.
10706 (for_each_per_buffer_object_at): New macro.
10707 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
10708 (Fbuffer_local_variables): Use it.
10709 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.

10711 struct buffer. Fix comment.
10712 (mark_overlay): New function.
10713 (mark_buffer): Use it. Use mark_vectorlike to mark normal
10714 Lisp area of struct buffer.
10715 (mark_object): Use it. Adjust marking of misc objects
10716 and related comments.
10718 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10720 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10721 wrapper that is not needed because the wrapped code is a no-op (zero
10722 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10723 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10725 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10727 * alloc.c (mark_buffer): Simplify. Remove prototype.
10728 (mark_object): Add comment. Reorganize marking of vector-like
10729 objects. Use CHECK_LIVE for all vector-like objects except buffers
10730 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10731 Avoid redundant calls to mark_vectorlike for bool vectors.
10733 2012-06-30 Glenn Morris <rgm@gnu.org>
10735 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10737 * epaths.in (PATH_SITELOADSEARCH): New.
10738 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10739 This is rather than relying on --enable-locallisppath elements
10740 having "site-lisp" in their names. (Bug#10208#25, 11658)
10742 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10744 * w32proc.c (sys_select): Accept and ignore one more argument.
10746 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10748 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10749 (pselect) [!MS_DOS]: Redirect to sys_select.
10751 * sysdep.c: Don't include dos.h and dosfns.h.
10753 * process.c (sys_select):
10754 * msdos.c (sys_select): Accept one more argument and ignore it.
10756 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10757 adapt data types and code to that.
10760 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10761 which clashes with the gnulib function of the same name.
10763 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10765 * font.c (font_style_to_value, font_style_symbolic)
10766 (font_prop_validate_style): Add type checks for values in
10769 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10771 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10774 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10776 * xdisp.c (try_window_id): Undo last change.
10778 * w32.c (getwd): Adjust commentary about startup_dir.
10779 (init_environment): Always call sys_access, even in non-MSVC
10780 builds. Don't chdir to the directory of the Emacs executable.
10781 This undoes code from 1997 which was justified by the need to
10782 "avoid conflicts when removing and renaming directories". But its
10783 downside was that every relative file name was being interpreted
10784 relative to the directory of the Emacs executable, which can never
10785 be TRT. In particular, it broke sys_access when called with
10786 relative file names.
10787 (sys_access): Map GetLastError to errno.
10789 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10791 * window.h (struct window): Change type of 'fringes_outside_margins'
10792 to bitfield. Fix comment. Adjust users accordingly.
10793 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
10795 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10798 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
10800 * gnutls.c (emacs_gnutls_handshake):
10801 Add QUIT to make the loop interruptible.
10803 2012-06-29 Glenn Morris <rgm@gnu.org>
10805 * charset.c (init_charset): Make lack of etc/charsets fatal.
10807 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10809 * editfns.c (region_limit): Fix type mismatch.
10811 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10813 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
10814 undefined. Convert from xassert to eassert.
10815 * nsmenu.m: Convert from xassert to eassert.
10816 * nsterm.m: Likewise.
10818 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
10820 * editfns.c (region_limit): Clip to narrowing (bug#11770).
10822 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
10824 Avoid integer overflow on scroll-left and scroll-right.
10825 * window.c (HSCROLL_MAX): New macro.

10981 Use sprintf return value instead of invoking strlen on result.
10982 In the old days this wasn't portable, since some sprintf
10983 implementations returned char *. But they died out years ago and
10984 Emacs already assumes sprintf returns int.
10985 Similarly for float_to_string.
10986 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

10993 * xfns.c (syms_of_xfns):
10994 Use sprintf or float_to_string result to avoid need to call strlen.
10995 * data.c (Fnumber_to_string):
10996 Use make_unibyte_string, since the string must be ASCII.
10997 * lisp.h, print.c (float_to_string): Now returns int length.
10998 * term.c (produce_glyphless_glyph):
10999 Use sprintf result rather than recomputing it.
11001 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

11009 strcasecmp if available.

11030 * xfns.c (x_window): Remove redundant cast.
11032 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
11034 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
11035 `const char *' to `char *' to avoid compiler warning.
11037 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11039 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
11040 instead of truncating it to 63 (admittedly a generous limit).
11042 * process.c: Fix spelling and caps in comments.
11044 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
11046 * emacs.c (setpgrp): Remove definition, unused.

11093 Remove unnecessary forward decls.
11095 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11097 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

11099 * dispnew.c (Fsleep_for, sit_for):
11100 * keyboard.c (kbd_buffer_get_event):
11101 * process.c (Faccept_process_output):
11102 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
11103 This improves on the previous patch, which introduced a bug
11104 when time_t is unsigned and as wide as intmax_t.
11105 See <http://bugs.gnu.org/9000#51>.
11107 2012-06-23 Eli Zaretskii <eliz@gnu.org>

11136 language ID in the event parameters.
11138 * w32term.c (w32_read_socket): Put the new keyboard codepage into
11139 event.code, not the obscure "character set ID".
11141 2012-06-23 Chong Yidong <cyd@gnu.org>

11170 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
11172 Support higher-resolution time stamps (Bug#9000).
11173 The time stamps are only nanosecond-resolution at the C level,
11174 since that's the best that any real-world system supports now.
11175 But they are picosecond-resolution at the Lisp level, as that's
11176 easy, and leaves room for future OS improvements.
11178 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
11181 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
11182 Don't get current time unless it's needed.
11184 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
11185 now provides it if it's absent.
11186 (start_atimer): Port to higher-res time stamps.
11187 Check for time stamp overflow. Don't get current time more
11188 often than is needed.
11190 * buffer.h (struct buffer): Buffer modtime now has high resolution.
11191 Include systime.h, not time.h.
11192 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
11194 * dired.c: Include stat-time.h.
11195 (Ffile-attributes): File times now have higher resolution.
11197 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
11198 (struct image): Timestamp now has higher resolution.
11200 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
11201 has at least microseconds now. All uses removed.
11202 (update_frame, update_single_window, update_window, update_frame_1)
11203 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
11204 (duration_to_sec_usec): Remove; no longer needed.
11206 * editfns.c (time_overflow): Now extern.
11207 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
11208 (float-time, Fformat_time_string, Fcurrent_time_string)

11211 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
11212 (decode_time_components, lisp_seconds_argument): New functions.
11213 (make_time): Now static.
11214 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
11215 Report an error if the time is invalid, rather than having the caller
11218 * fileio.c: Include <stat-time.h>
11219 (Fcopy_file): Copy higher-resolution time stamps.
11220 Prefer to set the time stamp via a file descriptor if that works.
11221 (Fset_file_times, Finsert_file_contents, Fwrite_region)
11222 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
11223 (Fvisited_file_modtime, Fset_visited_file_modtime):
11224 Support higher-resolution time stamps.
11226 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
11228 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
11230 * image.c (prepare_image_for_display, clear_image_cache)
11231 (lookup_image): Port to higer-resolution time stamps.
11233 * keyboard.c (start_polling, bind_polling_period):
11234 Check for time stamp overflow.
11235 (read_char, kbd_buffer_get_event, timer_start_idle)
11236 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
11237 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
11238 Port to higher-resolution time stamps. Do not assume time_t is signed.
11239 (decode_timer): New function. Timers are now vectors of length 9,
11240 not 8, to accommodate the picosecond component.
11241 (timer_check_2): Use it.
11243 * nsterm.m (select_timeout, timeval_subtract): Remove.
11244 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
11245 as they're a bit more accurate and handle overflow better.
11246 (ns_select): Change prototype to be compatible with pselect.
11247 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11248 * nsterm.h (ns_select): Adjust prototype.
11250 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
11251 us-resolution time stamps.
11252 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
11254 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
11256 * lisp.h (time_overflow): New decl.
11257 (wait_reading_process_output): First arg is now intmax_t, not int,
11258 to accommodate larger waits.
11260 * process.h (struct Lisp_Process.read_output_delay):
11261 Now counts nanoseconds, not microseconds.
11262 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
11264 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
11265 (wait_reading_process_output):
11266 Port to ns-resolution time stamps.
11267 (Faccept_process_output, wait_reading_process_output):
11268 Check for time stamp overflow. Do not assume time_t is signed.
11269 (select_wrapper): Remove; we now use pselect.
11270 (Fprocess_attributes): Now generates ns-resolution time stamps.
11272 * sysdep.c: Include utimens.h. Don't include utime.h
11273 or worry about struct utimbuf; gnulib does that for us now.
11274 (gettimeofday): Remove; gnulib provides a substitute.
11275 (make_timeval): New function.
11276 (set_file_times): Now sets ns-resolution time stamps.
11277 New arg FD; all uses changed.
11278 (time_from_jiffies, ltime_from_jiffies, get_up_time)
11279 (system_process_attributes):
11280 Now returns ns-resolution time stamp. All uses changed.
11281 Check for time stamp overflow.
11283 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
11284 provides a substitute now.
11286 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11287 since it guarantees struct timespec.
11288 (EMACS_TIME): Now struct timespec, so that we can support
11289 ns-resolution time stamps.
11290 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11291 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11292 (EMACS_USECS): Remove.
11293 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11294 so multiply the arg by 1000 before storing it.

11297 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

11304 (make_timeval, make_lisp_time, decode_time_components): New decls.
11305 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11306 that it mishandled time_t overflow. You can't compare by subtracting!
11307 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11308 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
11310 * term.c: Include <sys/time.h>.

11336 (timeval_subtract): Remove; no longer needed.
11337 (XTflash, XTring_bell, x_wait_for_event):

11347 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11348 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11349 staticidx goes up to 1597 out of 1600 = 0x640.)
11351 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11353 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
11354 Otherwise, the umask might be mistakenly 0 while handling input signals.
11356 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>

11380 (prepare_menu_bars): Likewise.
11382 * term.c (Ftty_top_frame): New function.
11384 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11386 Port byte-code-meter to modern targets.
11387 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
11388 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
11389 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
11390 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

11397 2012-06-18 Martin Rudalics <rudalics@gmx.at>
11399 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11400 gets killed during executing of this function (Bug#11665).
11401 Try to always return Qt when the buffer has been actually killed.
11402 (Vkill_buffer_query_functions): In doc-string say that functions
11403 run by this hook should not change the current buffer.
11405 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11407 Fix recently-introduced process.c problems found by static checking.

11427 * lisp.h (eassert): Assume C89 or later.
11428 This removes the need for CHECK.
11429 (CHECK): Remove. Its comments about always evaluating its
11430 argument were confusing, as 'eassert' typically does not evaluate
11433 * coding.c (produce_chars): Use ptrdiff_t, not int.
11435 * xterm.c (x_draw_underwave): Check for integer overflow.

11738 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
11740 Block-based vector allocation of small vectors.
11741 * lisp.h (struct vectorlike_header): New field `nbytes',
11742 adjust comment accordingly.
11743 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
11744 to denote vector blocks. Adjust users (live_vector_p,
11745 mark_maybe_pointer, valid_lisp_object_p) accordingly.
11746 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
11747 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
11748 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
11749 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),
11750 (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.
11751 (roundup_size): New constant.
11752 (struct vector_block): New data type.
11753 (vector_blocks, vector_free_lists, zero_vector): New variables.

11756 (sweep_vectors): New functions.
11757 (allocate_vectorlike): Return `zero_vector' as the only vector of
11758 0 items. Allocate new vector from block if vector size is less than
11759 or equal to VBLOCK_BYTES_MAX.
11760 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
11761 (init_alloc_once): Add call to init_vectors.
11763 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
11765 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
11767 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
11769 * doprnt.c (doprnt): Truncate multibyte char correctly.
11770 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
11771 would mishandle a string argument "Xc" if X was a multibyte
11772 character of length 2: it would truncate after X's first byte
11773 rather than including all of X.
11775 2012-06-06 Chong Yidong <cyd@gnu.org>
11777 * buffer.c (word_wrap): Doc fix.
11779 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

11791 binary via PaX flags if the paxctl utility is available.
11792 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
11793 Restore PaX flags to their default. (Bug#11398)
11795 2012-06-03 Chong Yidong <cyd@gnu.org>
11797 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
11798 buffer (Bug#11226).

11802 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
11803 (note_mode_line_or_margin_highlight): If there is no help echo,
11804 use mode-line-default-help-echo. Handle the case where the mouse
11805 position is past the end of the mode line string.
11807 * buffer.c (buffer_local_value_1): New function, split from
11808 Fbuffer_local_value; can return Qunbound.
11809 (Fbuffer_local_value): Use it.
11810 (Vmode_line_format): Docstring tweaks.
11812 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>

11818 * keyboard.c: Export real-this-command to Elisp.
11819 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
11820 and DEFVAR it. Update all users.
11822 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
11824 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11826 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11827 Convert pctcpu and pctmem to Lisp float properly.
11828 Let the compiler fold better, as 100.0/0x8000 is exact.
11830 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11832 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
11835 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
11837 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
11839 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
11841 For a 'struct window', replace some Lisp_Object fields to
11842 bitfields where appropriate, remove unused fields.
11843 * window.h (struct window): Remove unused 'last_mark_x' and
11844 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11845 change its type from Lisp_Object to bitfield.
11846 Change type of 'force_start', 'optional_new_start',
11847 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
11848 fields from Lisp_Object to bitfield. Adjust users accordingly.
11850 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11852 Pacify gcc -Wdouble-precision when using Xaw.
11853 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11854 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11855 Use 'float' consistently, rather than 'float' in most places
11856 and 'double' in a couple of places.
11858 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11860 * xdisp.c (handle_stop): Detect whether we have overlay strings
11861 loaded by testing it->current.overlay_string_index to be
11862 non-negative, instead of checking whether n_overlay_strings is
11863 positive. (Bug#11587)
11865 2012-05-31 Chong Yidong <cyd@gnu.org>
11867 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
11869 * doc.c (Fsubstitute_command_keys): Doc fix.
11871 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11873 * search.c (search_buffer): Remove calls to
11874 r_alloc_inhibit_buffer_relocation, as it is now called by
11875 maybe_unify_char, which was the cause of relocation of buffer text
11878 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11880 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11881 for the duration of call to load_charset, to avoid problems with
11882 callers of maybe_unify_char that access buffer text through C
11885 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11886 decrement the inhibition flag, instead of just setting or
11889 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11891 Remove obsolete '#define static' cruft.
11892 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11893 This #undef was "temporary" in 2000; it is no longer needed
11894 now that '#define static' has gone away.
11895 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11896 (gray_bitmap_bits): Remove; no longer needed.
11897 All uses replaced with definiens.
11898 * xterm.c: Include "bitmaps/gray.xbm".
11900 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
11902 Clean up __executable_start, monstartup when --enable-profiling.
11903 The following changes affect the code only when profiling.
11904 * dispnew.c (__executable_start): Rename from safe_bcopy.
11905 Define only on platforms that need it.
11906 * emacs.c: Include <sys/gmon.h> when profiling.
11907 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
11908 (__executable_start): Remove decl, since lisp.h does it now.
11909 (safe_bcopy): Remove decl; no longer has that name.
11910 (main): Coalesce #if into single bit of code, for simplicity.
11911 Cast pointers to uintptr_t, since standard libraries want integers
11913 * lisp.h (__executable_start): New decl.
11915 2012-05-31 Glenn Morris <rgm@gnu.org>
11917 * image.c (Fimagemagick_types): Doc fix.

11936 * lread.c (read1): Tiny simplification.
11938 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
11940 Do not create empty overlays with the evaporate property (Bug#9642).
11941 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11942 Bug#9642, but explicitly check that the buffer the overlay would
11943 be moved to is live and rearrange lines to make sure that errors
11944 will not put the overlay in an inconsistent state.
11945 (Fdelete_overlay): Cosmetics.
11947 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11949 * w32term.c (my_bring_window_to_top): New function.
11950 (x_raise_frame): Use handle returned by DeferWindowPos, which
11951 could be different from the original one.
11952 Call my_bring_window_to_top instead of my_set_foreground_window.

11961 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11963 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11964 This avoids undefined behavior that might cause the eassert
11965 to not catch an out-of-range value.
11967 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11969 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
11970 Update dependencies.

11974 * bidi.c (bidi_mirror_char): Fix last change.
11976 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

11981 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11983 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11984 Only r_alloc_inhibit_buffer_relocation needed to be added;
11985 the others were already declared.
11987 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11988 before checking whether it's out of range. Put the check inside
11990 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11992 2012-05-27 Ken Brown <kbrown@cornell.edu>
11994 * callproc.c (Fcall_process): Restore a line that was accidentally
11995 commented out in the 2011-02-13 change (bug#11547).
11997 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11999 * lisp.h [REL_ALLOC]: Add prototypes for external functions
12000 defined on ralloc.c.
12002 * buffer.c [REL_ALLOC]: Remove prototypes of
12003 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
12004 they are now on lisp.h.
12006 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
12008 * search.c (search_buffer): Use it to inhibit relocation of buffer
12009 text while re_search_2 is doing its job, because re_search_2 is
12010 passed C pointers to buffer text. (Bug#11519)
12012 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
12013 Update value to 24.
12015 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
12016 state after an additional call to move_it_in_display_line_to, keep
12017 the values of it->max_ascent and it->max_descent found for the
12019 (pos_visible_p): Revert the comparison against bottom_y to what it
12020 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
12023 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12025 Fix coding-related core dumps with gcc -ftrapv.
12026 The code was computing A - B, where A and B are pointers, and B is
12027 random garbage. This can lead to core dumps on platforms that
12028 have special pointer registers, and it also leads to core dumps on
12029 x86-64 when compiled with gcc -ftrapv. The fix is to compute
12030 A - B only when B is initialized properly.
12031 * coding.c (coding_set_source, coding_set_destination): Return void.
12032 (coding_change_source, coding_change_destinations): New functions,
12033 with the old behaviors of coding_set_source and coding_set_destination.
12034 All callers that need an offset changed to use these new functions.
12036 2012-05-26 Glenn Morris <rgm@gnu.org>
12038 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
12040 2012-05-26 Eli Zaretskii <eliz@gnu.org>

12043 * xdisp.c (draw_row_with_mouse_face):
12044 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
12046 * w32console.c: Include window.h.
12047 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
12049 (initialize_w32_display): Initialize mouse-highlight data.
12051 * w32inevt.c: Include termchar.h and window.h.
12052 (do_mouse_event): Support mouse-autoselect-window. When the mouse
12053 moves, call note_mouse_highlight. If help_echo changed, call
12054 gen_help_event to produce help-echo message in the echo area.
12055 Call clear_mouse_face if mouse_face_hidden is set in the mouse
12058 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12060 * lread.c (read1): Simplify slightly to avoid an overflow warning
12061 with GCC 4.7.0 on x86-64.
12063 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12065 * bidi.c (bidi_mirror_char): Revert last change: an int is
12066 definitely wide enough here.
12068 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
12070 Fix integer width and related bugs (Bug#9874).

12078 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
12080 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

12082 Use int, not EMACS_INT, where int is wide enough.
12083 (inhibit_garbage_collection, Fgarbage_collect):
12084 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12085 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
12086 int might not be wide enough.

12089 (bidi_at_paragraph_end, bidi_find_paragraph_start)
12090 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
12091 (bidi_level_of_next_char, bidi_move_to_visually_next):
12092 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12093 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
12094 (Fkill_buffer, Fset_buffer_major_mode)
12095 (advance_to_char_boundary, Fbuffer_swap_text)

12097 (overlay_touches_p, struct sortvec, record_overlay_string)
12098 (overlay_strings, recenter_overlay_lists)
12099 (adjust_overlays_for_insert, adjust_overlays_for_delete)

12104 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12105 (validate_region): Omit unnecessary test for b <= e,
12106 since that's guaranteed by the previous test.
12107 (adjust_overlays_for_delete): Avoid pos + length overflow.
12108 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
12109 (report_overlay_modification):
12110 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12111 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
12112 Omit pointer cast, which isn't needed anyway, and doesn't work
12113 after the EMACS_INT -> ptrdiff_t change.
12114 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
12115 * buffer.h: Adjust decls to match defn changes elsewhere.
12116 (struct buffer_text, struct buffer):
12117 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12118 Use EMACS_INT, not int, where int might not be wide enough.
12119 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
12120 not int, to avoid needless 32-bit limit on 64-bit hosts.
12121 (exec_byte_code): Use tighter memory-full test, one that checks
12122 for alloca overflow. Don't compute the address of the object just
12123 before an array, as that's not portable. Use EMACS_INT, not
12124 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
12125 * callint.c (Fcall_interactively):
12126 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12127 * callproc.c (call_process_kill, Fcall_process):

12137 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
12138 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12139 (casify_object): Avoid integer overflow when overallocating buffer.
12140 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
12141 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
12142 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
12143 * category.h (CATEGORYP): Don't assume arg is nonnegative.
12144 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

12150 Check that Vcode_version_map_vector is a vector.
12151 (resolve_symbol_ccl_program): Check that vector header is in range.
12152 Always copy the vector, so that we can check its contents reliably
12153 now rather than having to recheck each instruction as it's being
12154 executed. Check that vector words fit in 'int'.
12155 (ccl_get_compiled_code, Fregister_ccl_program)
12156 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
12157 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
12158 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
12159 contents are in range.

12162 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):

12170 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

12188 to be a character. Avoid int overflow if max_char is close

12200 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
12201 where the argument is EMACS_INT, and this behavior is not intended.
12202 * chartab.c (Fmake_char_table, Fset_char_table_range)

12204 Don't assume fixnum fits in int.

12830 (merge_face_heights): Remove unnecessary cast to EMACS_INT.
12831 (Finternal_make_lisp_face): Don't allocate more than MAX_FACE_ID.
12832 (face_at_buffer_position, face_for_overlay_string)
12833 (face_at_string_position):
12834 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12835 (merge_faces): Use int, not EMACS_INT, where int is wide enough.
12836 * xfns.c (x_set_menu_bar_lines, x_set_tool_bar_lines, x_icon_verify)
12838 Check that fixnums are in proper range for system types.
12839 (Fx_create_frame, x_create_tip_frame, Fx_show_tip)
12840 (Fx_hide_tip, Fx_file_dialog, Fx_select_font):
12841 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12842 (Fx_change_window_property): Don't assume fixnums fit in int.
12843 * xfont.c (xfont_chars_supported):
12844 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12845 * xmenu.c (Fx_popup_dialog, set_frame_menubar)
12846 (create_and_show_popup_menu, create_and_show_dialog, xmenu_show):
12847 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12848 * xml.c (parse_region):
12849 * xrdb.c (magic_file_p):
12850 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12851 * xselect.c (TRACE1): Don't assume pid_t promotes to int.
12852 (x_get_local_selection, x_reply_selection_request)
12853 (x_handle_selection_request, wait_for_property_change):
12854 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12855 (selection_data_to_lisp_data): Use short, not EMACS_INT, where
12856 short is wide enough.
12857 (x_send_client_event): Don't assume fixnum fits in int.
12858 * xterm.c (x_x_to_emacs_modifiers):
12859 Don't assume EMACS_INT overflows nicely into int.
12860 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
12861 may come from Lisp.
12862 (handle_one_xevent): NATNUMP can eval its arg twice.
12863 (x_connection_closed):
12864 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12865 * xterm.h: Adjust decls to match defn changes elsewhere.
12866 (struct scroll_bar): Use struct vectorlike_header
12867 rather than rolling our own approximation.
12868 (SCROLL_BAR_VEC_SIZE): Remove; not used.
12870 2012-05-25 Glenn Morris <rgm@gnu.org>
12872 * lisp.mk (lisp): Update for more files being compiled now.
12874 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
12876 * lread.c: Remove `read_pure' which makes no difference.
12877 (read_pure): Remove var.
12878 (unreadpure): Remove function.
12879 (readevalloop): Don't call read_list with -1 flag.
12880 (read1, read_vector): Don't test read_pure any more.
12881 (read_list): Simplify.
12883 * fileio.c, character.h: Minor style tweaks.
12885 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
12887 * window.h (clip_changed): Remove useless declaration.
12889 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
12891 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
12892 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
12894 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
12897 This directory predates autoconf and is no longer needed nowadays.
12898 Move its few remaining bits of functionality to where they're needed.
12899 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
12900 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
12901 * m/template.h: Remove.
12902 * Makefile.in (M_FILE): Remove. All uses removed.
12903 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
12904 * lisp.h (USE_LSB_TAG):
12905 * mem-limits.h (EXCEEDS_LISP_PTR):
12906 Use VAL_MAX, not VALBITS, in #if.
12907 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
12908 (EMACS_UINT): Define unconditionally now.
12909 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
12910 (BITS_PER_EMACS_INT): New constants, replacing
12911 what used to be in config.h, but not useful in #if.
12912 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
12913 define them any more.
12914 (VAL_MAX): New macro.
12916 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
12917 BITS_PER_EMACS_INT, in #if.
12918 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
12919 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
12920 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
12921 * s/ms-w32.h (DATA_START):
12922 Move here from removed file m/intel386.h.
12923 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
12924 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
12926 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
12928 Assume C89 or later.
12929 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
12930 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
12932 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
12933 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
12934 * textprop.c, tparam.c (NULL): Remove.
12935 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
12936 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
12937 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
12938 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
12939 * xterm.c (input_signal_count): Assume volatile works.
12941 2012-05-21 Ken Brown <kbrown@cornell.edu>
12943 * xgselect.c (xg_select): Fix first argument in call to 'select'
12946 2012-05-20 Ken Brown <kbrown@cornell.edu>
12948 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
12949 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
12951 2012-05-19 Ken Brown <kbrown@cornell.edu>
12953 * xfns.c (x_in_use): Remove `static' qualifier.
12954 * xterm.h (x_in_use): Declare.
12955 * xgselect.c: Include xterm.h.
12956 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
12957 and `display_arg' (bug#9754).
12959 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
12961 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
12963 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
12964 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
12966 2012-05-18 Eli Zaretskii <eliz@gnu.org>
12968 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
12970 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
12971 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
12973 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12974 reference to image_cache->refcount.
12975 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12977 2012-05-17 Juri Linkov <juri@jurta.org>
12979 * search.c (Fword_search_regexp, Fword_search_backward)
12980 (Fword_search_forward, Fword_search_backward_lax)
12981 (Fword_search_forward_lax): Move functions to isearch.el
12982 (bug#10145, bug#11381).
12984 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12986 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12988 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12990 * lread.c (init_obarray): Declare Qt and Qnil as special.
12992 2012-05-14 Glenn Morris <rgm@gnu.org>
12994 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12995 Put "libexec" before "bin", for the sake of init_callproc_1.
12997 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12999 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
13001 * unexaix.c: Port to more-recent AIX compilers.
13002 (report_error, report_error_1, make_hdr, copy_sym)
13003 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
13004 Make arguments const char *, not char *, to avoid violations of C
13005 standard and to fix some AIX warnings reported by Gilles Pion.
13007 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13009 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
13010 already have overlays loaded.
13011 (handle_single_display_spec): Before returning without displaying
13012 fringe bitmap, synchronize the bidi iterator with the main display
13013 iterator, by calling iterate_out_of_display_property.
13014 (iterate_out_of_display_property): Detect buffer iteration by
13015 testing that it->string is a Lisp string.
13016 (get_next_display_element): When the current object is exhausted,
13017 and there's something on it->stack, call set_iterator_to_next to
13018 proceed with what's on the stack, instead of returning zero.
13019 (set_iterator_to_next): If called at the end of a Lisp string,
13020 proceed to consider_string_end without incrementing string
13021 position. Don't increment display vector index past the end of
13022 the display vector. (Bug#11417)
13023 (pos_visible_p): Don't report a position visible when move_it_to
13024 stopped at the last line of window, which happens to be scanned
13025 backwards by the bidi iteration. (Bug#11464)
13027 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13029 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
13030 and right-margin display specs even if the spec is invalid or we
13031 are on a TTY, and thus unable to display on the fringes.
13032 That's because the text with the property will not be displayed anyway,
13033 so we need to signal to the caller that this is a "replacing"
13034 display spec. This fixes display when the spec is invalid or we
13037 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13039 * unexaix.c (make_hdr): Fix typo in prototype.
13040 This bug broke the build on AIX. Problem reported by Gilles Pion.
13042 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
13044 * keyboard.c (kbd_buffer_get_event): Read special events also in
13045 batch mode. (Bug#11415)
13047 2012-05-12 Glenn Morris <rgm@gnu.org>
13049 * ns.mk: Update for ns_appbindir no longer having trailing "/".
13051 2012-05-12 Eli Zaretskii <eliz@gnu.org>
13053 * lisp.mk (lisp): Add newcomment.elc.
13055 2012-05-12 Glenn Morris <rgm@gnu.org>
13057 * Makefile.in (MKDIR_P): New, set by configure.
13058 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
13060 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
13062 Remove unused function hourglass_started.
13063 * dispextern.h (hourglass_started):
13064 * w32fns.c (hourglass_started):
13065 * xdisp.c (hourglass_started): Remove.
13067 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
13069 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
13070 Update dependencies.
13072 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
13074 * xgselect.c (xg_select): Put maxfds+1 into a var.
13075 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
13077 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
13079 2012-05-10 Dave Abrahams <dave@boostpro.com>
13081 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
13082 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
13084 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
13086 * dbusbind.c (xd_registered_buses): New internal Lisp object.
13087 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
13088 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
13089 Initialize xd_registered_buses.
13091 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
13093 Untag more efficiently if USE_LSB_TAG.
13094 This is based on a proposal by YAMAMOTO Mitsuharu in
13095 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
13096 For an admittedly artificial (nth 8000 longlist) benchmark on
13097 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
13098 Emacs's overall text size by 1%.
13099 * lisp.h (XUNTAG): New macro.
13100 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
13101 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
13102 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
13103 * eval.c (Fautoload):
13104 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
13105 * frame.h (XFRAME): Use XUNTAG.
13107 Port recent dbusbind.c changes to 32-bit --with-wide-int.
13108 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
13109 Remove unportable assumptions about print widths of types like
13111 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
13112 intptr_t when converting between pointer and integer, to avoid GCC
13113 warnings about wrong width.
13115 2012-05-09 Eli Zaretskii <eliz@gnu.org>
13117 * w32proc.c (new_child): Force Windows to reserve only 64KB of
13118 stack for each reader_thread, instead of defaulting to 8MB
13119 determined by the linker. This avoids failures in creating
13120 subprocesses on Windows 7, see the discussion in this thread:
13121 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
13123 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
13125 Fix up display of the *Minibuf-0* buffer in the mini window.
13126 * keyboard.c (read_char): Don't clear the echo area if there's no
13128 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
13129 contents of *Minibuf-0*) if there's no message displayed in its stead.
13131 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
13133 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
13136 2012-05-06 Chong Yidong <cyd@gnu.org>
13138 * lisp.mk (lisp): Update.
13140 2012-05-05 Jim Meyering <meyering@redhat.com>
13142 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
13144 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
13146 * data.c (PUT_ERROR): New macro.
13147 (syms_of_data): Use it. Add new error type `user-error'.
13148 * undo.c (user_error): New function.
13149 (Fprimitive_undo): Use it.
13150 * print.c (print_error_message): Adjust print style for `user-error'.
13151 * keyboard.c (user_error): New function.
13152 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
13154 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
13156 Do not limit current-time-string to years 1000..9999.
13157 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
13158 (Fcurrent_time_string): Support any year that is supported by the
13159 underlying localtime representation. Don't use asctime, as it
13160 has undefined behavior for years outside the range -999..9999.
13162 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
13164 Fix race conditions involving setenv, gmtime, localtime, asctime.
13165 Without this fix, interrupts could mess up code that uses these
13166 nonreentrant functions, since setting TZ invalidates existing
13167 tm_zone or tzname values, and since most of these functions return
13168 pointers to static storage.
13169 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
13170 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
13171 Grow the critical sections to include not just invoking
13172 localtime/gmtime, but also accessing these functions' results
13173 including their tm_zone values if any, and any related TZ setting.
13174 (format_time_string): Last arg is now struct tm *, not struct tm **,
13175 so that the struct tm is saved in the critical section.
13176 All callers changed. Simplify allocation of initial buffer, partly
13177 motivated by the fact that memory allocation needs to be outside
13178 the critical section.
13180 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
13182 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
13183 with RESET_INTERVAL.
13185 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
13186 Remove duplicated buffer name initialization.
13188 2012-05-02 Jim Meyering <jim@meyering.net>
13190 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
13192 * xfns.c (x_window): Use xstrdup (Bug#11375).
13194 2012-05-02 Eli Zaretskii <eliz@gnu.org>
13196 * xdisp.c (pos_visible_p): If already at a newline from the
13197 display string before the 'while' loop, don't walk back the glyphs
13198 from it3.glyph_row. Solves assertion violation when the display
13199 string begins with a newline (egg.el). (Bug#11367)
13201 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
13203 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
13206 2012-05-01 Glenn Morris <rgm@gnu.org>
13208 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
13209 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
13210 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
13211 All were removed before 23.1.
13213 * dispnew.c: Remove HAVE_LIBNCURSES test;
13214 it is always true on relevant platforms.
13216 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
13217 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
13219 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
13221 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
13223 * .gdbinit (xpr): Remove checks for no longer existing misc types.
13224 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
13227 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
13229 Do not avoid creating empty evaporating overlays (Bug#9642).
13230 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13231 That is, do not delete an evaporating overlay if it becomes
13232 empty after its bounds are adjusted to fit within its buffer.
13233 This fix caused other problems, and I'm reverting it until we get
13234 to the bottom of them.
13236 2012-04-27 Chong Yidong <cyd@gnu.org>
13238 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
13240 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13242 * xdisp.c (pos_visible_p): If the window start position is beyond
13243 ZV, start the display from buffer beginning. Prevents assertion
13244 violation in init_iterator when the minibuffer window is scrolled
13245 via the scroll bar.
13247 * window.c (window_scroll_pixel_based): Likewise.
13249 2012-04-27 Chong Yidong <cyd@gnu.org>
13251 * keymap.c (where_is_internal): Doc fix (Bug#10872).
13253 2012-04-27 Glenn Morris <rgm@gnu.org>
13255 * fileio.c (Fcopy_file, Fset_file_selinux_context):
13256 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13258 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13260 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):

13270 (add_menu_item): If the call to AppendMenuW (via
13271 unicode_append_menu) fails, disable Unicode menus only if we are
13272 running on Windows 9X/Me.
13274 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13276 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

13297 Do not create empty overlays with the evaporate property (Bug#9642).
13298 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13299 if it becomes empty after its bounds are adjusted to fit within
13300 its buffer. Without this fix, in a nonempty buffer (let ((o
13301 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13302 yields an empty overlay that has the evaporate property, which is
13303 not supposed to happen.

13326 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13327 (__malloc_size_t, __malloc_ptrdiff_t):
13328 Remove. All uses removed, replaced by the definiens if needed,
13329 since we can assume C89 or better now.

13418 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13420 * sysdep.c [__FreeBSD__]: Minor cleanups.
13421 (list_system_processes, system_process_attributes) [__FreeBSD__]:
13422 Use Emacs indenting style more consistently. Avoid some casts.

13434 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
13436 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
13437 It is never used otherwise.
13439 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
13441 * print.c (print_preprocess): Only check print_depth if print-circle

13448 * process.c (wait_reading_process_output): If EIO occurs on a pty,
13449 set the status to "failed" and ensure that sentinel is run.
13451 2012-04-20 Glenn Morris <rgm@gnu.org>
13453 * process.c (Fset_process_inherit_coding_system_flag)
13454 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

13482 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
13483 -Wunused-result, -Wunused-variable. This should go away once
13484 the Emacs and Gnulib regex code is merged.
13485 (xmalloc, xrealloc): Now static.

13504 New extern decls, to avoid calling undeclared functions.
13505 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
13506 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
13507 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13508 (NEED_MEM_INSERT): New macro.
13509 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13510 Remove one incorrect comment and fix another.

13525 Remove decls. This fixes an "It stinks!".
13527 * alloc.c (which_symbols): Fix alignment issue / type clash.
13529 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>

13546 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
13547 * s/netbsd.h, s/sol2-6.h:
13548 Remove definition of GC_MARK_STACK, since the default now works.
13549 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

13577 2012-04-11 Daniel Colascione <dancol@dancol.org>
13579 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13580 against is gone. It's better to use vfork now so that when Cygwin
13581 gains a new, working vfork, we use it automatically (bug#10398).
13583 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

13633 (Fdefvar): Caller changed.
13635 * callint.c (Finteractive, Fcall_interactively):
13636 * minibuf.c (Fread_variable): Callers changed.
13638 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13640 * xdisp.c (set_cursor_from_row): If the display string appears in
13641 the buffer at position that is closer to point than the position
13642 after the display string, display the cursor on the first glyph of
13643 the display string. Fixes cursor display when a 'display' text
13644 property immediately follows invisible text. (Bug#11094)
13646 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13648 composite.c: use 'double' consistently
13649 * composite.c (get_composition_id): Use 'double' consistently
13650 instead of converting 'float' to 'double' and vice versa; this is
13651 easier to understand and avoids a GCC warning.
13653 2012-04-09 Glenn Morris <rgm@gnu.org>
13655 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13656 preparation for dumping it with emacs. (Bug#4789)

13691 Support building on MS-Windows with libxml2.
13693 * makefile.w32-in (OBJ2): Add xml.$(O).
13694 (GLOBAL_SOURCES): Add xml.c.
13695 ($(BLD)/xml.$(O)): New dependency list.
13697 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
13698 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
13699 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
13700 [!WINDOWSNT]: New macros.
13701 (init_libxml2_functions, libxml2_loaded_p): New functions.
13702 (parse_region): Call fn_xmlCheckVersion instead of using the macro
13703 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
13704 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
13705 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13707 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13708 Call init_libxml2_functions before calling libxml2 functions.
13709 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13711 * emacs.c: Don't include libxml/parser.h.
13712 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
13713 xmlCleanupParser directly.
13715 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
13717 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13719 * indent.c (Fvertical_motion): If there is a display string at
13720 point, use it.vpos to compute how many lines to backtrack after
13721 move_it_to point. (Bug#11133)
13723 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13725 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13726 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13727 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13728 macros related to unification of CJK characters. For the details,
13729 see the discussion following the message here:
13730 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
13732 2012-04-04 Chong Yidong <cyd@gnu.org>
13734 * keyboard.c (Vdelayed_warnings_list): Doc fix.
13736 2012-04-01 Eli Zaretskii <eliz@gnu.org>
13738 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
13739 instead of alloca. (Bug#11138)
13741 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
13743 * w32menu.c (is_simple_dialog): Properly check lisp types.
13746 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13748 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13749 position we get to after a call to move_it_to fails the
13750 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13751 only if we wind up in a string from display property. (Bug#11063)
13753 * window.c (Fdelete_other_windows_internal): Invalidate the row
13754 and column information about mouse highlight, so that redisplay
13755 restores it after reallocating the glyph matrices. (Bug#7464)
13757 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13758 string comes from a `display' text property, use the buffer
13759 position of that property as if we actually saw that position in
13761 (move_it_by_lines): Remove the assertion that
13762 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13763 violated when there's a before-string at the beginning of a line.
13766 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13768 * xdisp.c (append_space_for_newline): If the default face was
13769 remapped, use the remapped face for the appended newline.
13770 (extend_face_to_end_of_line): Use the remapped default face for
13771 extending the face to the end of the line.
13772 (display_line): Call extend_face_to_end_of_line when the default
13773 face was remapped. (Bug#11068)
13775 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13777 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
13779 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13781 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
13783 2012-03-27 Glenn Morris <rgm@gnu.org>
13785 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
13788 2012-03-26 Kenichi Handa <handa@m17n.org>
13790 * dispextern.h (struct glyph): Fix previous change. Change the
13791 bit length of glyphless.ch to 25 (Bug#11082).
13793 2012-03-26 Chong Yidong <cyd@gnu.org>
13795 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13796 (command_loop_1): Use it; inhibit selection update for
13797 handle-select-window too (Bug#8996).
13799 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
13801 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13803 2012-03-25 Kenichi Handa <handa@m17n.org>
13805 * dispextern.h (struct glyph): Change the bit length of
13806 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13808 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13810 * s/ms-w32.h (tzname): Include time.h before redirecting to
13811 _tzname. Fixes the MSVC build. (Bug#9960)
13813 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
13815 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13818 * xterm.c (XTread_socket): Only modify handling_signal if
13819 !SYNC_INPUT. (Bug#11080)
13821 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13823 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13824 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13825 when fetching a multibyte character consumes more bytes than
13826 CHAR_BYTES returns, due to unification of CJK characters in
13827 string_char. (Bug#11073)
13829 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13831 * process.c (wait_reading_process_output): Handle pty disconnect
13832 by refraining from sending oneself a SIGCHLD (bug#10933).
13834 2012-03-22 Chong Yidong <cyd@gnu.org>

13839 Mark string as coming from a prefix property.
13840 (handle_face_prop): Use default face for prefix strings (Bug#4281).
13841 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
13843 2012-03-21 Chong Yidong <cyd@gnu.org>
13845 * xfaces.c (Vface_remapping_alist): Doc fix.
13847 2012-03-20 Eli Zaretskii <eliz@gnu.org>
13849 * w32proc.c (Fw32_set_console_codepage)
13850 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
13853 2012-03-20 Chong Yidong <cyd@gnu.org>
13855 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
13856 to reflect default non-nil value of redisplay-dont-pause.
13858 2012-03-19 Kenichi Handa <handa@m17n.org>
13860 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
13861 it fit in a valid range (Bug#11003).
13863 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13865 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13866 that is not from display property, accept the row as a "cursor
13867 row" if one of the string's character has a non-nil `cursor'
13868 property. Fixes cursor positioning when there are newlines in
13869 overlay strings, e.g. in icomplete.el. (Bug#11035)
13871 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13873 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13875 2012-03-12 Chong Yidong <cyd@gnu.org>
13877 * eval.c (inhibit_lisp_code): Rename from
13878 inhibit_window_configuration_change_hook; move from window.c.
13880 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13881 * window.c (run_window_configuration_change_hook)
13882 (syms_of_window): Callers changed.

13888 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
13890 2012-03-10 Chong Yidong <cyd@gnu.org>
13892 * frame.c (other_visible_frames): Don't assume the selected frame
13893 is visible (Bug#10955).
13895 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
13897 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).

13901 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
13902 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13905 2012-03-03 Glenn Morris <rgm@gnu.org>
13907 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13909 2012-03-02 Eli Zaretskii <eliz@gnu.org>
13911 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
13912 position past the first glyph_row that ends at ZV. (Bug#10902)
13913 (redisplay_window, next_element_from_string): Fix typos in
13915 (redisplay_window): Pass to move_it_vertically the margin in
13916 pixels, not in screen lines.
13918 2012-03-02 Glenn Morris <rgm@gnu.org>
13920 * buffer.c (buffer-list-update-hook): Doc fix.
13922 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13924 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13925 push_it before setting up the iterator for the first overlay
13926 string, even if we have an empty string loaded.
13927 (next_overlay_string): If there's an empty string on the iterator
13928 stack, pop the stack. (Bug#10903)
13930 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13932 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13933 Suggested by Stefan Monnier in
13934 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13935 * alloc.c (widen_to_Lisp_Object): New static function.
13936 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13937 and widening them to Lisp_Objects. This would work even if
13938 USE_LSB_TAG is defined and wide integers are used, which might
13939 happen in a future version of Emacs.
13941 2012-02-25 Chong Yidong <cyd@gnu.org>
13943 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13946 * xselect.c (Fx_selection_exists_p): Doc fix.
13947 (x_clipboard_manager_save_all): Print an informative message
13948 before saving to clipboard manager.
13950 2012-02-24 Chong Yidong <cyd@gnu.org>
13952 * keyboard.c (process_special_events): Handle all X selection
13953 requests in kbd_buffer, not just the next one (Bug#8869).
13955 2012-02-23 Chong Yidong <cyd@gnu.org>
13957 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13958 call when setting menu-bar-lines and tool-bar-lines parameters.
13959 (unwind_create_frame_1): New helper function.
13961 * window.c (inhibit_window_configuration_change_hook): New var.
13962 (run_window_configuration_change_hook): Obey it.
13963 (syms_of_window): Initialize it.
13965 2012-02-22 Chong Yidong <cyd@gnu.org>
13967 * xterm.c (x_draw_image_relief): Add missing type check for
13968 Vtool_bar_button_margin (Bug#10743).
13970 2012-02-21 Chong Yidong <cyd@gnu.org>
13972 * fileio.c (Vfile_name_handler_alist): Doc fix.
13974 * buffer.c (Fget_file_buffer): Protect against invalid file
13975 handler return value.
13977 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
13979 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
13980 when computing $valmask.
13982 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13983 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13984 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13985 It's useless in that case, and it can cause problems on hosts
13986 that allocate halves of EMACS_INT values separately.
13987 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13988 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13989 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13990 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13991 it avoids undefined behavior on hosts where shifting right by more
13992 than the word width has undefined behavior.
13994 2012-02-19 Chong Yidong <cyd@gnu.org>
13996 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13997 (Funhandled_file_name_directory, Ffile_name_as_directory)
13998 (Fdirectory_file_name, Fexpand_file_name)
13999 (Fsubstitute_in_file_name): Protect against invalid file handler
14000 return values (Bug#10845).
14002 2012-02-18 Eli Zaretskii <eliz@gnu.org>
14004 * .gdbinit (pitx): Fix incorrect references to fields of the
14007 2012-02-17 Chong Yidong <cyd@gnu.org>
14009 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
14011 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
14013 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
14014 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
14016 2012-02-15 Chong Yidong <cyd@gnu.org>
14018 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
14019 marked as special. Also, starting docstrings with * is obsolete.
14021 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
14023 * gnutls.c (emacs_gnutls_write): Fix last change.
14025 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
14027 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
14030 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
14032 * keymap.c (Fsingle_key_description): Handle char ranges.
14034 2012-02-12 Chong Yidong <cyd@gnu.org>
14036 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
14037 as that creates a dangerous corner case.
14039 * window.c (Fdelete_window_internal): Invalidate the mouse
14040 highlight (Bug#9904).
14042 2012-02-12 Glenn Morris <rgm@gnu.org>
14044 * xselect.c (Fx_own_selection_internal)
14045 (Fx_get_selection_internal, Fx_disown_selection_internal)
14046 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
14047 * nsselect.m (Fx_own_selection_internal)
14048 (Fx_disown_selection_internal, Fx_selection_exists_p)
14049 (Fx_selection_owner_p, Fx_get_selection_internal):
14050 Sync docs and argument specs with the xselect.c versions.
14052 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
14054 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
14056 2012-02-11 Eli Zaretskii <eliz@gnu.org>
14058 * w32select.c (Fx_selection_exists_p): Sync doc string and
14059 argument list with xselect.c. (Bug#10783)
14061 * w16select.c (Fx_selection_exists_p): Sync doc string and
14062 argument list with xselect.c. (Bug#10783)
14064 2012-02-10 Glenn Morris <rgm@gnu.org>
14066 * fns.c (Fsecure_hash): Doc fix.
14068 2012-02-09 Kenichi Handa <handa@m17n.org>
14070 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
14072 2012-02-07 Chong Yidong <cyd@gnu.org>
14074 * buffer.c (Fbuffer_local_variables)
14075 (buffer_lisp_local_variables): Handle unbound vars correctly;
14076 don't let Qunbound leak into Lisp.
14078 2012-02-07 Glenn Morris <rgm@gnu.org>
14080 * image.c (Fimagemagick_types): Doc fix.
14082 * image.c (imagemagick-render-type): Change it from a lisp object
14083 to an integer. Move the doc here from the lisp manual.
14084 Treat all values not equal to 0 the same.
14086 2012-02-06 Chong Yidong <cyd@gnu.org>
14088 * doc.c (store_function_docstring): Avoid applying docstring of
14089 alias to base function (Bug#2603).
14091 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
14093 * .gdbinit (pp1, pv1): Remove redundant defines.
14096 2012-02-04 Chong Yidong <cyd@gnu.org>
14098 * nsterm.m: Declare a global (Bug#10694).
14100 2012-02-04 Eli Zaretskii <eliz@gnu.org>
14102 * w32.c (get_emacs_configuration_options):
14103 Include --enable-checking, if specified, in the return value.
14105 2012-02-04 Martin Rudalics <rudalics@gmx.at>
14107 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
14108 after rounding frame sizes. (Bug#9723)
14110 2012-02-04 Eli Zaretskii <eliz@gnu.org>
14112 * keyboard.c (adjust_point_for_property): Don't position point
14113 before BEGV. (Bug#10696)
14115 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
14117 Handle overflow when computing char display width (Bug#9496).
14118 * character.c (char_width): Return EMACS_INT, not int.
14119 (char_width, c_string_width): Check for overflow when
14120 computing the width; this is possible now that individual
14121 characters can have unbounded width. Problem introduced
14122 by merge from Emacs 23 on 2012-01-19.
14124 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
14126 * dbusbind.c (Fdbus_register_method): Mention the return value
14127 :ignore in the docstring.
14129 2012-02-02 Glenn Morris <rgm@gnu.org>
14131 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.
14133 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:
14134 Unconditionally set to t. (Bug#10673)

14139 2012-02-02 Kenichi Handa <handa@m17n.org>
14141 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
14142 0, do not call append_composite_glyph.
14144 2012-02-02 Kenichi Handa <handa@m17n.org>
14146 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
14148 (x_produce_glyphs): If the component of a composition is a null
14149 string, set it->pixel_width to 1 to avoid zero-width glyph.
14151 2012-02-01 Eli Zaretskii <eliz@gnu.org>
14153 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
14154 first 2 arguments are identical. This makes inserting large
14155 output from a subprocess an order of magnitude faster on
14156 MS-Windows, where all sbrk'ed memory is always contiguous.
14158 2012-01-31 Glenn Morris <rgm@gnu.org>
14160 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

14686 * xdisp.c (redisplay_window): If cursor row is not fully visible
14687 after recentering, and scroll-conservatively is set to a large
14688 number, scroll window by a few more lines to make the cursor fully
14689 visible and out of scroll-margin. (Bug#10105)
14690 (start_display): Don't move to the next line if the display should
14691 start at a newline that is part of a display vector or an overlay
14692 string. (Bug#10119)

14775 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
14776 is set, removing the need for VIRT_ADDRESS_VARIES.
14777 (PURE_P): Use a more-efficient implementation that needs just one
14778 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
14779 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
14780 to 4 (xorl, subq, cmpq, setbe).
14781 * alloc.c (pure): Always extern now, since that's the
14782 VIRT_ADDR_VARIES behavior.
14783 (PURE_POINTER_P): Use a single comparison, not two, for
14784 consistency with the new puresize.h.
14785 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
14786 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

14792 (erase_phys_cursor, update_window_cursor, show_mouse_face)
14793 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
14794 behave as if the cursor position were at the window margin.
14796 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14797 and the cursor position is out of bounds, behave as if the cursor
14798 position were at the window margin. (Bug#10075)
14800 2011-11-18 Chong Yidong <cyd@gnu.org>
14802 * window.c (Fwindow_combination_limit): Make first argument

14821 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
14823 * xdisp.c (row_hash): New function, body extracted from
14824 compute_line_metrics.
14825 (compute_line_metrics): Call row_hash, instead of computing the
14828 * dispnew.c (verify_row_hash): Call row_hash for computing the
14829 hash code of a row, instead of duplicating code from xdisp.c.
14831 * dispextern.h (row_hash): Add prototype.
14833 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
14835 * frame.c (delete_frame): Don't delete the terminal when the last

14861 (Fsplit_window_internal, saved_window)
14862 (Fset_window_configuration, save_window_save): Rename all
14863 occurrences of window_nest to window_combination_limit.

14869 2011-11-14 Eli Zaretskii <eliz@gnu.org>
14871 * xdisp.c (display_line): Move the call to
14872 highlight_trailing_whitespace before the call to
14873 compute_line_metrics, since the latter needs to see the final
14874 faces of all the glyphs to compute ROW's hash value.
14875 Fixes assertion violations in row_equal_p. (Bug#10035)
14877 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
14879 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
14880 just return (bug#10044).
14882 2011-11-12 Eli Zaretskii <eliz@gnu.org>
14884 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14885 with user-defined heap size. Bump the default size of the temacs

14889 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
14890 current_matrix and desired_matrix. (Bug#9990)
14891 (verify_row_hash) [XASSERTS]: New function.

14938 Avoid some portability problems by eschewing 'extern inline' functions.
14939 The trivial performance wins aren't worth the portability hassles; see
14940 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14942 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

15008 * xmenu.c (cleanup_widget_value_tree): New function.
15009 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
15010 calling free_menubar_widget_value_tree directly (Bug#9830).

15016 (window_box_width, window_box_left, window_box_left_offset)
15017 (window_box_right, window_box_right_offset): Declare extern.
15018 Otherwise, these inline functions do not conform to C99 and
15019 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
15020 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
15021 * intervals.c (adjust_intervals_for_insertion)
15022 (adjust_intervals_for_deletion): Now extern, because otherwise the
15023 extern inline functions 'offset_intervals' couldn't refer to it.
15024 (static_offset_intervals): Remove.
15025 (offset_intervals): Rewrite using the old contents of
15026 static_offset_intervals. The old version didn't conform to C99
15027 because an extern inline function contained a reference to an
15028 identifier with static linkage.

15080 * nsfns.m: Declare image_cache_refcount if GLYPH_DEBUG.
15081 (unwind_create_frame): New function (Bug#9943).
15082 (Fx_create_frame): Restructure code to be more similar to the one in
15083 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).

15130 * regex.c <re_char> [_MSC_VER]: A separate definition for MSVC.
15132 2011-11-04 Eli Zaretskii <eliz@gnu.org>
15134 * xdisp.c (note_mouse_highlight): If either of
15135 previous/next-single-property-change returns nil, treat that as
15136 the beginning or the end of the buffer. (Bug#9955)
15138 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
15140 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
15141 label is not null (Bug#9951).
15142 (xg_tool_item_stale_p): Handle the fact that wimage and/or wlbl

15160 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
15161 Don't stop backward scan on the continuation glyph, even though
15162 its CHARPOS is positive.
15163 (mouse_face_from_buffer_pos, note_mouse_highlight):
15164 Rename cover_string to disp_string.
15166 2011-11-01 Martin Rudalics <rudalics@gmx.at>
15168 * window.c (temp_output_buffer_show): Don't use
15169 Vtemp_buffer_show_specifiers.
15170 (Vtemp_buffer_show_specifiers): Remove unused variable.
15172 2011-10-30 Eli Zaretskii <eliz@gnu.org>
15174 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
15175 past the beginning of the current glyph matrix.
15177 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
15179 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
15180 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
15181 HAVE_GTK3 (Bug#9869).

15190 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
15191 (get_current_wm_state): Return non-zero if not hidden,
15192 check for _NET_WM_STATE_HIDDEN (Bug#9893).

15199 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
15200 so that this new function doesn't get optimized away by a
15201 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
15203 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
15205 * frame.h (MOUSE_HL_INFO): Remove excess parens.
15207 2011-10-29 Eli Zaretskii <eliz@gnu.org>

15223 2011-10-29 Glenn Morris <rgm@gnu.org>
15225 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
15226 Not clear what it was for, and it causes various bugs. (Bug#9839)
15228 2011-10-28 Eli Zaretskii <eliz@gnu.org>
15230 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
15231 possible random value that matches one of those tested as
15232 condition to clear the mouse face.
15234 2011-10-28 Chong Yidong <cyd@gnu.org>
15236 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.

15250 2011-10-28 Eli Zaretskii <eliz@gnu.org>
15252 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
15253 <oslsachem@gmail.com> for helping to debug this.
15255 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
15256 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
15257 (g_b_init_get_glyph_outline_w): New static variables.
15258 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)

15261 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
15263 (w32font_open_internal, compute_metrics):
15264 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
15265 instead of calling the "wide" APIs directly.
15267 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
15269 * w32.h (syms_of_w32font): Add prototype.
15271 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
15273 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
15274 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
15275 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
15276 (Fmove_to_window_line): Doc fix.
15278 2011-10-27 Chong Yidong <cyd@gnu.org>
15280 * process.c (make_process): Set gnutls_state to NULL.
15282 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
15283 non-NULL, regardless of GNUTLS_INITSTAGE.
15284 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
15285 an error. Set process slots as soon as we allocate them.
15287 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
15289 2011-10-27 Chong Yidong <cyd@gnu.org>
15291 * gnutls.c (emacs_gnutls_deinit): New function.

15295 * process.c (make_process): Initialize GnuTLS credentials to NULL.
15296 (deactivate_process): Call emacs_gnutls_deinit.
15298 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
15300 * image.c (x_create_x_image_and_pixmap):
15301 * w32.c (sys_rename, w32_delayed_load):
15302 * w32font.c (fill_in_logfont):

15308 extracted from Fw32_default_color_map.
15309 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
15311 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
15313 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
15315 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
15317 * keyboard.c (test_undefined): New function (bug#9751).
15318 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
15320 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
15322 * sysdep.c (init_sys_modes): Fix the check for the controlling
15323 terminal (Bug#6649).
15325 2011-10-20 Eli Zaretskii <eliz@gnu.org>
15327 * dispextern.h (struct bidi_it): New member next_en_type.
15329 * bidi.c (bidi_line_init): Initialize the next_en_type member.
15330 (bidi_resolve_explicit_1): When next_en_pos is valid for the
15331 current character, check also for next_en_type being WEAK_EN.
15332 (bidi_resolve_weak): Don't enter the expensive loop if the current
15333 position is before next_en_pos. Record the bidi type of the first
15334 non-ET, non-BN character we find, in addition to its position.
15335 (bidi_level_of_next_char): Invalidate next_en_type when
15336 next_en_pos is over-stepped.
15338 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
15340 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15341 * editfns.c: Rewrite current-time-zone so that it invokes
15342 the equivalent of (format-time-string "%Z") to get the time zone name.
15343 This fixes a bug when the time zone name contains characters that
15344 need converting from the system time locale to Emacs internal format.
15345 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15346 that patch fixed format-time-string to do the conversion, but
15347 I forgot to fix current-time-zone.
15348 (format_time_string): New function, containing most of
15349 what Fformat_time_string used to contain.
15350 (Fformat_time_string): Rewrite in terms of format_time_string.
15351 This doesn't change this function's behavior.
15352 (current-time-zone): Rewrite to use format_time_string.
15353 This fixes the bug reported by Michael Schierl in
15354 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15355 Jason Rumney's 2007-06-07 change worked around this bug, but
15357 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15359 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15361 * xdisp.c (start_display): If the character at POS is displayed
15362 via a display vector, reset IT->current.dpvec_index to zero.
15363 (try_window_reusing_current_matrix): If a line ends in a display
15364 vector or the next line starts in a display vector, continue
15365 redrawing the window even though the character position of
15366 start_row was reached.
15369 2011-10-18 Chong Yidong <cyd@gnu.org>
15371 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15372 with nobreak-char-display too.
15374 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15376 Fix part 3 of bug#9771.
15377 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15378 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15379 non-neutral characters if the current character is a paragraph
15380 separator (a.k.a. Newline). This avoids running the same
15381 expensive loop twice, once when we consume the preceding newline
15382 and the other time when the line actually needs to be displayed.
15383 Avoid the loop when we see neutrals on the base embedding level
15384 following a character whose directionality is the same as the
15385 paragraph's. This avoids running the expensive loop when a line
15386 ends in a long sequence of neutrals, like control characters.
15387 Add assertion against STRONG_AL type. Slightly rearrange code
15388 that determines the type of a neutral given the first non-neutral
15390 (bidi_level_of_next_char): Set next_en_pos to zero when
15391 invalidating its info.
15393 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15395 * xdisp.c (push_display_prop): Determine whether to record string
15396 or buffer position by IT->string, not by IT->method. Allow
15397 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15398 (move_it_vertically_backward): Don't look for character position
15399 immediately after the newline when in a continuation line.
15402 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15404 * window.c (coordinates_in_window): Rewrite and delabelize
15405 vertical border check. (Bug#5357) (Bug#9618)
15407 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
15409 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15410 errors in XSetWindowBorder (bug#9310).
15412 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15414 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15415 avoid crash when xmalloc overrun checking is enabled.
15417 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15419 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15420 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15421 cursor motion with <left> and <right> arrow keys.
15423 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15424 some callers set that themselves.
15426 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15428 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15429 display string and the previous row comes from the same string and
15430 is empty. (Bug#9739) (Bug#9738)
15432 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15434 * doc.c (get_doc_string): Encode file name (bug#9735).
15436 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15438 * bidi.c (bidi_level_of_next_char):
15439 * xdisp.c (get_visually_first_element): Remove old incorrect
15440 comments regarding the Unicode Line Separator character.
15442 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15444 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15446 * alloc.c (Fgc_status): Do not access beyond zombies array
15447 boundary if nzombies > MAX_ZOMBIES.
15448 * alloc.c (dump_zombies): Add missing format specifier.
15450 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15452 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15453 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15455 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15456 Some packages use them to denote characters with modifiers.
15458 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15460 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15461 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15462 matching a pp-number. Rename parameter var to var1.
15464 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15466 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15468 2011-10-08 Glenn Morris <rgm@gnu.org>
15470 * callint.c (Fcall_interactively): Give a more explicit error for the
15471 'c' case with a non-character input. (Bug#8479)
15473 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15475 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15477 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15478 lines that are hscrolled on the left.
15480 * dispnew.c (buffer_posn_from_coords): Account for a possible
15481 presence of header-line. (Bug#4426)
15483 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15485 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15486 Don't advertise functionality which we discourage or doesn't work.
15488 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15490 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15491 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15492 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15493 this makes Emacs dump core during garbage collection on rare
15494 occasions. sizeof is obviously inferior to offsetof here, so
15495 stick with offsetof.
15496 (GC_POINTER_ALIGNMENT): New macro.
15497 (mark_memory): Omit 3rd (offset) arg; caller changed.
15498 Don't assume EMACS_INT alignment is the same as pointer alignment.
15500 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15502 * keyboard.c (read_key_sequence_remapped): New var.
15503 (read_key_sequence): Compute remapping in the right buffer.
15504 (command_loop_1): Use read_key_sequence's remapping directly.
15506 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15508 * dired.c (file_name_completion): Don't expand file name.
15509 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15510 before checking file name handler.
15512 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15513 they've been requested explicitly (bug#9591).
15515 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15517 * keymap.c (Fsingle_key_description): Use make_specified_string
15518 instead of build_string to build string from push_key_description.
15521 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15523 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15524 This fixes a Y2038 bug on 64-bit hosts.
15525 * buffer.c (reset_buffer):
15526 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15527 (Fclear_buffer_auto_save_failure):
15528 Use 0, not -1, to represent an unset failure time, since time_t
15529 might not be signed.
15531 Remove dependency on glibc malloc internals.
15532 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15533 Move back here from lisp.h, but with their new implementations.
15534 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15535 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15536 * charset.c (charset_table_init): New static var.
15537 (syms_of_charset): Use it instead of xmalloc. This removes a
15538 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15539 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15540 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15541 Move back to alloc.c.
15542 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15543 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15545 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15547 * nsterm.m (windowDidResize): Call x_set_window_size only when
15548 ns_in_resize is true. Otherwise set pixelwidth/height and
15549 call change_frame_size (Bug#9628).
15551 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15553 Port --enable-checking=all to Fedora 14 x86-64.
15554 * charset.c (syms_of_charset): Also account for glibc malloc's
15555 internal overhead when calculating the initial malloc maximum.
15557 Port --enable-checking=all to Fedora 14 x86.
15558 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15560 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15561 (overrun_check_realloc, overrun_check_free):
15562 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15563 That way, xmalloc returns a properly-aligned pointer even if
15564 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15565 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15566 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15567 into account when calculating the initial malloc maximum.
15568 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15569 Move here from alloc.c, so that charset.c can use it too.
15570 Properly align; the old code wasn't right for common 32-bit hosts
15571 when configured with --enable-checking=all.
15572 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15573 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15575 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15577 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15580 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15582 * xdisp.c (compute_display_string_end): If there's no display
15583 string at CHARPOS, return -1.
15585 * bidi.c (bidi_fetch_char): When compute_display_string_end
15586 returns a negative value, treat the character as a normal
15587 character not covered by a display string. (Bug#9624)
15589 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15591 * lread.c (Fread_from_string): Fix typo in docstring.
15593 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15595 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15596 newline, reseat the iterator instead of bidi-iterating there one
15597 character at a time. (Bug#9610)
15598 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15599 TO_CHARPOS if the bidi iterator is at base embedding level.
15601 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15603 * lread.c (readevalloop): Use correct code for NBSP.
15604 (read1): Likewise. (Bug#9608)
15606 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15608 * dbusbind.c (Fdbus_register_signal): When service is not
15609 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15611 2011-09-25 Glenn Morris <rgm@gnu.org>
15613 * buffer.c (truncate-lines): Doc fix.
15615 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15617 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15618 (Fset_window_next_buffers): Doc fix.
15620 2011-09-24 Glenn Morris <rgm@gnu.org>
15622 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15624 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15626 Fix minor problems found by static checking.
15627 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
15628 * indent.c (Fvertical_motion): Fix == vs = typo.
15630 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15632 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15633 Default value is now t. Doc fix.
15635 * indent.c (Fvertical_motion): Compute and apply the overshoot
15636 logic when moving up, not only when moving down. Fix the
15637 confusing name and values of the it_overshoot_expected variable;
15638 logic changes accordingly. (Bug#9254) (Bug#9549)
15640 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15641 CHARPOS is covered by a display string which includes newlines.
15642 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15643 is covered by a display string with embedded newlines.
15645 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15647 * dbusbind.c (Fdbus_register_signal): Add match rule to
15648 Vdbus_registered_objects_table. (Bug#9581)
15649 (Fdbus_register_method, Vdbus_registered_objects_table):
15652 2011-09-24 Jim Meyering <meyering@redhat.com>
15654 do not ignore write error for any output size
15655 The previous change was incomplete.
15656 While it makes emacs --batch detect the vast majority of stdout
15657 write failures, errors were still ignored whenever the output size is
15658 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15659 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15660 && echo FAIL: ignored write error
15661 FAIL: ignored write error
15662 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15663 && echo FAIL: ignored write error
15664 FAIL: ignored write error
15665 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15667 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15669 * emacs.c (Fkill_emacs): In noninteractive mode exit
15670 non-successfully if a write error occurred on stdout. (Bug#9574)
15672 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15674 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15677 * dispextern.h (struct it): Update the comment documenting what
15680 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15682 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15683 a display string, extend search for cursor position to end of row.
15684 (find_row_edges): If the row ends in a newline from a display
15685 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15686 Handle the case of a display string with multiple newlines.
15687 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15688 non-empty line. Fixes confusing cursor motion with arrow keys at
15689 the beginning of a line that starts with whitespace.
15691 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15693 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15696 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15698 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15699 boolean (Bug#9154).
15701 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15703 * xdisp.c (display_line): Record maximum and minimum buffer
15704 positions even if no glyphs were produced (e.g., by a zero-width
15705 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15706 buffer positions that will be removed from the glyph row because
15708 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15709 column is beyond frame width: don't subtract 1 "pixel" when
15710 computing width of the stretch.
15711 (reseat_at_next_visible_line_start): Undo the change made on
15712 2011-09-17 that saved paragraph information and restored it after
15713 the call to `reseat'. (Bug#9545)
15715 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15717 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15718 and turn window cursor on if cleared (Bug#9415).
15720 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15722 * search.c (boyer_moore): Take unibyte characters from pattern
15723 literally. (Bug#9458)
15725 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15727 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
15729 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
15731 Fix minor problem found by static checking.
15732 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
15733 initialized, to pacify gcc -Wuninitialized.
15735 * fileio.c: Report proper errno when syscall falls.
15736 (Finsert_file_contents): Save and restore errno,
15737 so that report_file_error outputs the correct diagnostic.
15738 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15740 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15742 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15744 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15746 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15747 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
15749 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15751 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15752 about the current paragraph and restore it after the call to reseat.
15754 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15755 (bidi_find_paragraph_start): Search back for paragraph beginning
15756 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15757 (bidi_move_to_visually_next): Only trigger paragraph-related
15758 computations when the last character is a newline or at EOB, not
15759 just any NEUTRAL_B. (Bug#9470)
15761 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15762 truncated lines if point is covered by a display string. (Bug#9524)
15764 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15766 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15767 (cons_to_x_long): New function.
15768 (lisp_data_to_selection_data): Use it. Correct the test for
15769 short-versus-long data; it was negated. Break out of vector
15770 loop, for efficiency, when a long datum is discovered.
15772 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15774 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15776 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15778 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
15779 GCC PR/17406) by declaring this function with external scope.
15781 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15783 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
15784 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
15786 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
15788 * editfns.c (Fformat): Correctly handle text properties on "%%".

15796 * xdisp.c (get_next_display_element)
15797 (fill_composite_glyph_string): Add comments about special meaning
15798 of TAB characters in a composition.
15800 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15802 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15803 This occurs when processing a multibyte format.
15804 Problem reported by Wolfgang Jenker.
15806 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15808 * xdisp.c (try_cursor_movement): Only check for exact match if
15809 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15811 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15813 Remove unused external symbols.
15814 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15815 * xdisp.c (calc_pixel_width_or_height): Now static.
15816 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
15817 * indent.c (check_display_width):
15818 * w32term.c: Fix comment to match code.
15819 * xterm.c, xterm.h (x_catching_errors): Remove.
15821 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15823 * xselect.c: Use signed conversions more consistently (Bug#9498).
15824 (selection_data_to_lisp_data): Assume incoming selection data are
15825 signed integers, not unsigned. This is to be consistent with
15826 outgoing selection data, which was modified to use signed integers
15827 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15828 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15829 expects long, not unsigned long.
15831 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15833 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15834 computation of loop end. Reported by Johan Bockgård
15837 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15839 * frame.c (Fother_visible_frames_p): Function deleted.
15841 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15843 * indent.c (compute_motion): Process display vector front to back
15844 rather than the other way around. (Bug#2496)
15846 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15848 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15850 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15852 * minibuf.c (Fread_from_minibuffer): Doc fix.
15854 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15856 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15857 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15859 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15861 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15862 value for non-existent files.
15864 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15866 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15867 set its "size" to -1. This will set the modtime_size field of
15868 the corresponding buffer to -1, which is what
15869 verify-visited-file-modtime expects for files that do not exist.
15872 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15874 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15876 * lisp.h: ... from here. push_key_description is no longer
15877 defined in keyboard.c, so its declaration should not be in
15878 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15879 logically belongs with push_key_description.
15881 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15883 * buffer.h: Include <sys/types.h> instead of <time.h>.
15884 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15885 Problem reported by Herbert J. Skuhra.
15887 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15889 * xml.c (parse_region): Make the parsing work for
15890 non-comment-starting XML files again (bug#9144).
15892 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15894 * image.c (gif_load): Fix calculation of bottom and right corner.
15897 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15899 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15900 redisplay in small windows.
15902 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15904 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15906 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15908 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15909 Operate on live windows only.
15911 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15913 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15915 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15917 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15918 only under bidi iteration.
15920 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15922 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15924 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15926 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15927 Without this fix, the command to link temacs failed due to an
15928 undefined symbol __builtin_isnan. This is because
15929 /usr/include/iso/math_c99.h #defines isnan(x) to
15930 __builtin_isnan(x), but the bundled gcc, which identifies itself
15931 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15933 * floatfns.c (isnan): #undef, and then #define to a clone of
15935 (Fisnan): Always define, since it's always available now.
15936 (syms_of_floatfns): Always define isnan at the Lisp level.
15938 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15940 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15942 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15944 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15945 The previous code assumed that file offsets (off_t values) fit in
15946 EMACS_INT variables, which is not true on typical 32-bit hosts.
15947 The code messed up by falsely reporting buffer overflow in cases
15948 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15949 when "big" contains more than 2**29 bytes, even though this
15950 inserts just one byte and does not overflow the buffer.
15951 (Finsert_file_contents): Store file offsets as off_t
15952 values, not as EMACS_INT values. Check for overflow when
15953 converting between EMACS_INT and off_t. When checking for
15954 buffer overflow or for overlap, take the offsets into account.
15955 Don't use EMACS_INT for small values where int suffices.
15956 When checking for overlap, fix a typo: ZV was used where
15957 ZV_BYTE was intended.
15958 (Fwrite_region): Don't assume off_t fits into 'long'.
15959 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15961 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15963 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15965 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15967 sprintf-related integer and memory overflow issues (Bug#9412).
15969 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15970 (esprintf, exprintf, evxprintf): New functions.
15971 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15972 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15973 (modify_event_symbol): Do not assume that the length of
15974 name_alist_or_stem is safe to alloca and fits in int.
15975 (Fexecute_extended_command): Likewise for function name and binding.
15976 (Frecursion_depth): Wrap around reliably on integer overflow.
15977 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15978 since some callers pass EMACS_INT values.
15979 (Fsingle_key_description): Don't crash if symbol name contains more
15980 than MAX_ALLOCA bytes.
15981 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15982 (get_minibuffer): Arg is now EMACS_INT, not int.
15983 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15984 (esprintf, exprintf, evxprintf): New decls.
15985 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15987 * dbusbind.c (signature_cat): New function.
15988 (xd_signature, Fdbus_register_signal):
15989 Do not overrun buffer; instead, report string overflow.
15991 * dispnew.c (add_window_display_history): Don't overrun buffer.
15992 Truncate instead; this is OK since it's just a log.
15994 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15995 even if the time zone offset is outlandishly large.
15996 Don't mishandle offset == INT_MIN.
15998 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15999 when creating daemon; the previous buffer-overflow check was incorrect.
16001 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
16002 which has the guts of the old verror function.
16004 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
16005 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
16007 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
16008 (font_unparse_xlfd): Don't blindly alloca long strings.
16009 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
16010 fits in int, when using sprintf. Use single snprintf to count
16011 length of string rather than counting it via multiple sprintfs;
16012 that's simpler and more reliable.
16013 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
16014 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
16015 sprintf, in case result does not fit in int.
16017 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
16018 (fontset_from_font): Print it.
16020 * frame.c (tty_frame_count): Now printmax_t, not int.
16021 (make_terminal_frame, set_term_frame_name): Print it.
16022 (x_report_frame_params): In X, window IDs are unsigned long,
16023 not signed long, so print them as unsigned.
16024 (validate_x_resource_name): Check for implausibly long names,
16025 and don't assume name length fits in 'int'.
16026 (x_get_resource_string): Don't blindly alloca invocation name;
16027 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
16030 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
16031 (xg_check_special_colors, xg_set_geometry):
16032 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
16034 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
16035 Use esprintf, not sprintf, in case result does not fit in int.
16037 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16038 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
16039 it as a large positive number.

16041 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16043 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
16044 in case result does not fit in int.
16046 * print.c (float_to_string): Detect width overflow more reliably.
16047 (print_object): Make sprintf buffer a bit bigger, to avoid potential
16048 buffer overrun. Don't assume list length fits in 'int'. Treat
16049 print length of 0 as 0, not as infinity; to be consistent with other
16050 uses of print length in this function. Don't overflow print length
16051 index. Don't assume hash table size fits in 'long', or that
16052 vectorlike size fits in 'unsigned long'.
16054 * process.c (make_process): Use printmax_t, not int, to format
16055 process-name gensyms.
16057 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
16059 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
16060 to avoid potential buffer overrun.
16062 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
16063 if X resource line is longer than 512 bytes.
16065 * xfns.c (x_window): Make sprintf buffer a bit bigger
16066 to avoid potential buffer overrun.
16068 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
16070 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
16072 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16074 Integer overflow fixes for scrolling, etc.
16075 Without these, Emacs silently mishandles large integers sometimes.
16076 For example, "C-u 4294967297 M-x recenter" was treated as if
16077 it were "C-u 1 M-x recenter" on a typical 64-bit host.
16079 * xdisp.c (try_window_id): Check Emacs fixnum range before
16080 converting to 'int'.
16082 * window.c (window_scroll_line_based, Frecenter):
16083 Check that an Emacs fixnum is in range before assigning it to 'int'.
16084 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
16085 values converted from Emacs fixnums.
16086 (Frecenter): Don't wrap around a line count if it is out of 'int'
16087 range; instead, treat it as an extreme value.
16088 (Fset_window_configuration, compare_window_configurations):
16089 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
16091 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
16092 that can exceed INT_MAX. Check that EMACS_INT value is in range
16093 before assigning it to the (possibly-narrower) index.
16094 (match_limit): Don't assume that a fixnum can fit in 'int'.
16096 * print.c (print_object): Use ptrdiff_t, not int, for index that can
16099 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
16100 (Fvertical_motion): Don't wrap around LINES values that don't fit
16101 in 'int'. Instead, treat them as extreme values. This is good
16102 enough for windows, which can't have more than INT_MAX lines anyway.
16104 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16106 * Require libxml/parser.h to avoid compilation warning.
16108 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
16110 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
16111 since this reportedly can destroy thread storage.
16113 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
16115 * syntax.c (find_defun_start): Update all cache variables if
16116 exiting early (Bug#9401).
16118 2011-08-30 Eli Zaretskii <eliz@gnu.org>
16120 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
16122 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
16123 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
16124 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
16126 * term.c (tty_append_glyph): New function.
16127 (produce_stretch_glyph): Static function and its prototype deleted.
16129 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
16132 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
16134 * image.c (parse_image_spec): Check for nonnegative, not for positive,
16135 when checking :margin (Bug#9390).
16136 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
16137 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
16138 so that the name doesn't mislead. All uses changed.
16140 2011-08-28 Johan Bockgård <bojohan@gnu.org>
16142 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
16145 2011-08-27 Eli Zaretskii <eliz@gnu.org>
16147 * xdisp.c (move_it_to): Don't bail out early when reaching
16148 position beyond to_charpos, if we are scanning backwards.
16149 (move_it_vertically_backward): When DY == 0, make sure we get to
16150 the first character in the line after the newline.
16152 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
16154 * ccl.c: Improve and simplify overflow checking (Bug#9196).
16155 (ccl_driver): Do not generate an out-of-range pointer.
16156 (Fccl_execute_on_string): Remove unnecessary check for
16157 integer overflow, noted by Stefan Monnier in
16158 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
16159 Remove a FIXME that didn't need fixing.
16160 Simplify the newly-introduced buffer reallocation code.
16162 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
16164 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
16166 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
16168 Integer and memory overflow issues (Bug#9196).
16170 * doc.c (get_doc_string): Rework so that
16171 get_doc_string_buffer_size is the actual buffer size, rather than
16172 being 1 less than the actual buffer size; this makes xpalloc more
16175 * image.c (x_allocate_bitmap_record, cache_image):
16176 * xselect.c (Fx_register_dnd_atom):
16177 Simplify previous changes by using xpalloc.
16179 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
16180 since either will do and ptrdiff_t is convenient with xpalloc.
16182 * charset.c (charset_table_size)
16183 (struct charset_sort_data.priority): Now ptrdiff_t.
16184 (charset_compare): Don't overflow if priorities differ greatly.
16185 (Fsort_charsets): Don't assume list length fits in int.
16186 Check for size-calculation overflow when allocating sort data.
16187 (syms_of_charset): Allocate an initial charset table that is
16188 just under 64 KiB, to avoid problems with glibc malloc and mmap.
16190 * cmds.c (internal_self_insert): Check for size-calculation overflow.
16192 * composite.h (struct composition.glyph_len): Now int, not unsigned.
16193 The actual value is always <= INT_MAX, and leaving it unsigned made
16194 overflow checking harder.
16196 * dispextern.h (struct glyph_matrix.rows_allocated)
16197 (struct face_cache.size): Now ptrdiff_t, for convenience in use
16198 with xpalloc. The values are still always <= INT_MAX.
16200 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
16202 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
16203 (SAFE_NALLOCA): New macro.
16205 * region-cache.c (struct boundary.pos, find_cache_boundary)
16206 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
16207 (set_cache_region, invalidate_region_cache)
16208 (revalidate_region_cache, know_region_cache, region_cache_forward)
16209 (region_cache_backward, pp_cache):
16210 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
16211 so that ptrdiff_t * can be passed to xpalloc.
16212 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
16213 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
16214 (pp_cache): Don't assume cache_len fits in int.
16215 * region-cache.h: Adjust extern decls to match.
16217 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
16218 EMACS_INT, since either will do, for xpalloc.
16220 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
16221 (xnmalloc, xnrealloc, xpalloc): New functions.
16223 * bidi.c (bidi_shelve_header_size): New constant.
16224 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
16225 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
16227 * bidi.c (bidi_cache_shrink):
16228 * buffer.c (overlays_at, overlays_in, record_overlay_string)
16230 Don't update size of array until after memory allocation succeeds,
16231 because xmalloc/xrealloc may not return.
16232 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16233 now that we have proper integer overflow checking.
16234 (record_overlay_string, overlay_strings): Catch overflows when
16235 calculating size of overlay_str_buf.
16237 * callproc.c (Fcall_process): Check for size overflow when
16238 calculating size of args2.
16239 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
16240 Normally we prefer signed values, but sticking with ptrdiff_t would
16241 require adding more-complicated checks.
16243 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16244 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
16245 Redo buffer-overflow calculations to avoid integer overflow.
16246 Add a FIXME comment where memory seems to be over-allocated.
16248 * character.c (Fstring): Check for size-calculation overflow.
16250 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
16251 unnecessary integer overflow. Check for size overflow.
16252 (encode_coding_object): Don't update size until xmalloc succeeds.
16254 * composite.c (get_composition_id): Check for overflow in glyph
16255 length calculations.
16257 Integer and memory overflow fixes for display code.
16258 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
16259 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
16260 (scrolling_window): Check for overflow in size calculations.
16261 (line_draw_cost, realloc_glyph_pool, add_row_entry):
16262 Don't assume glyph table len fits in int.

16264 (row_table_size): Now ptrdiff_t, not int.
16265 (scrolling_window): Avoid overflow in size calculations.

16272 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
16273 (get_doc_string): Check for size calculation overflow.
16274 Don't update size until allocation succeeds.
16275 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
16276 EMACS_INT, where ptrdiff_t will do.
16277 (Fsubstitute_command_keys): Check for string overflow.
16279 * editfns.c (set_time_zone_rule): Don't assume environment length
16281 (message_length): Now ptrdiff_t, not int.
16282 (Fmessage_box): Don't update size until allocation succeeds.
16283 Don't assume message length fits in int.
16284 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16286 * emacs.c (main): Do not reallocate argv, since there is a null at
16287 the end that can be overwritten, and this way there's no need to
16288 worry about size-calculation overflow.
16289 (sort_args): Check for size-calculation overflow.
16291 * eval.c (init_eval_once, grow_specpdl): Don't update size until
16293 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
16295 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
16296 (x_set_scroll_bar_width, x_figure_window_size):
16297 Check for integer overflow.
16298 (x_set_alpha): Do not assume XINT fits in int.
16300 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
16301 This is for the members text_lines, text_cols, total_lines, total_cols,
16302 where the system imposes an 'int' limit.
16304 * fringe.c (Fdefine_fringe_bitmap):
16305 Don't update size until alloc works.
16307 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
16308 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
16310 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
16311 Check for size-calculation overflow.
16312 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
16313 do, as we prefer signed integers.
16314 (id_to_widget.max_size, id_to_widget.used)
16315 (xg_store_widget_in_map, xg_remove_widget_from_map)
16316 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
16317 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
16318 Use and return ptrdiff_t, not int.
16319 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
16320 * gtkutil.h: Change prototypes to match the above.
16322 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
16323 are duplicate now that they've been promoted to lisp.h.
16324 (x_allocate_bitmap_record, x_alloc_image_color)
16325 (make_image_cache, cache_image, xpm_load):
16326 Don't update size until alloc is done.
16327 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
16329 Check for size calculation overflow.
16330 (ct_colors_allocated_max): New constant.
16331 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
16334 * keyboard.c (read_char, menu_bar_items, tool_bar_items)

16336 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
16337 Use ptrdiff_t, not int, to count maps.
16338 (read_char_minibuf_menu_prompt): Check for overflow in size
16339 calculations. Don't update size until allocation succeeds.
16340 Redo calculations to avoid overflow.
16341 * keyboard.h: Change prototypes to match the above.
16343 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
16345 (current_minor_maps): Check for size calculation overflow.
16346 * keymap.h: Change prototypes to match the above.
16348 * lread.c (read1, init_obarray): Don't update size until alloc done.
16350 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

16367 (Fset_match_data): Don't assume list lengths fit in 'int'.
16369 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
16370 for command line length. Do not attempt to address one before the
16371 beginning of an array, as that's not portable.
16373 * term.c (max_frame_lines): Remove; unused.
16374 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
16376 (encode_terminal_code, calculate_costs): Check for size
16377 calculation overflow.

16380 done. Redo calculations to avoid overflow.
16381 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
16383 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
16384 subtracting pointers.

16399 Use ptrdiff_t, not int, for sizes.
16400 (Finternal_make_lisp_face, cache_face):
16401 Check for size calculation overflow.
16402 (cache_face): Treat size calculation overflows as if they were
16403 memory exhaustion (the usual treatment), rather than aborting.
16405 * xfns.c (x_encode_text, x_set_name_internal)
16406 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16407 sizes, since they can exceed INT_MAX in size. Check for size
16408 calculation overflow.
16410 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
16411 (xg_select): Check for size calculation overflow.
16412 Don't update size until alloc done.
16414 * xrdb.c (get_environ_db): Don't assume path length fits in int,
16415 as sprintf is limited to int lengths.
16417 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
16418 (X_LONG_MIN): New macros.
16419 Use them to make the following changes clearer.
16420 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16421 This change doesn't affect the value now, but it may help remind
16422 future maintainers not to raise the value too much later.
16423 (SELECTION_QUANTUM): Remove, replacing with ...
16424 (selection_quantum): ... new function, which avoids overflow.
16426 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16427 assumption that selection length fits in 'int'.
16428 (x_reply_selection_request, x_handle_selection_request)
16429 (x_get_window_property, receive_incremental_selection)
16430 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
16431 (lisp_data_to_selection_data, clean_local_selection_data):

16433 (x_reply_selection_request, x_get_window_property)
16434 (receive_incremental_selection, x_property_data_to_lisp):
16435 Redo calculations to avoid overflow.
16436 (x_reply_selection_request): When sending hint, ceiling it at
16437 X_LONG_MAX rather than relying on wraparound overflow to send
16439 (x_get_window_property, receive_incremental_selection)
16440 (lisp_data_to_selection_data, x_property_data_to_lisp):
16441 Check for size-calculation overflow.
16442 (x_get_window_property, receive_incremental_selection)
16443 (lisp_data_to_selection_data, Fx_register_dnd_atom):
16444 Don't store size until memory allocation succeeds.
16445 (x_get_window_property): Plug memory leak on memory exhaustion.
16446 Don't double-block input; malloc is safe here. Don't assume 2**34
16447 - 4 fits in unsigned long. Add an xassert to check
16448 XGetWindowProperty overflow. Be more careful about overflow
16449 calculations, and distinguish size from memory overflow better.
16450 (receive_incremental_selection): When tracing, don't assume
16451 unsigned int is less than INT_MAX.
16452 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
16453 harmful) conversions of unsigned short to int.
16454 (lisp_data_to_selection_data): Don't assume that integers
16455 in the range -65535 through -1 fit in an X unsigned short.
16456 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16457 result parameters unless successful. Rely on cons_to_unsigned
16458 to report problems with elements; the old code wasn't right anyway.
16459 (x_check_property_data): Check for int overflow; we cannot use
16460 a wider type due to X limits.
16461 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

16466 (x_term_init): Check for size calculation overflow.
16467 (x_color_cells): Don't store size until memory allocation succeeds.
16468 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
16469 Don't assume alloca size is less than MAX_ALLOCA.
16470 (x_term_init): Don't assume length fits in int (sprintf is limited
16473 Use ptrdiff_t for composition IDs.

16493 * lisp.h (hash_lookup, hash_put):
16494 * minibuf.c (Ftest_completion):
16495 Use ptrdiff_t for hash table indexes, not int (which is too
16496 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16497 32-bit --with-wide-int hosts).
16499 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16500 Add a FIXME comment about memory leaks.
16501 (syms_of_charset): Don't assume xmalloc returns.
16503 Don't assume that stated character widths fit in int.

16505 * character.h (CHAR_WIDTH):
16506 * indent.c (MULTIBYTE_BYTES_WIDTH):
16507 Use sanitize_char_width to avoid undefined and/or bad behavior
16508 with outlandish widths.
16509 * character.h (sanitize_tab_width): Rename from sanitize_width,
16510 now that we have two such functions. All uses changed.

16522 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
16524 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
16525 Remove unreachable code.
16526 (read_hex, load_charset_map_from_file): Check for integer overflow.
16528 * xterm.c: Don't go over XClientMessageEvent limit.
16529 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16530 (x_send_scroll_bar_event): Likewise. Check that the size does not
16531 exceed limits imposed by XClientMessageEvent, as well as the usual
16532 ptrdiff_t and size_t limits.
16534 * keyboard.c: Overflow, signedness and related fixes.
16535 (make_lispy_movement): Use same integer type in forward decl
16536 that is used in the definition.
16537 (read_key_sequence, keyremap_step):
16538 Change bufsize argument back to int, undoing my 2011-03-30 change.
16539 We prefer signed types, and int is wide enough here.
16540 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16541 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16542 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16543 length, not size_t. Use ptrdiff_t for index, not int.
16544 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16545 possibility of integer overflow.
16547 Overflow, signedness and related fixes for images.

16557 * xdisp.c (calc_pixel_width_or_height):
16558 * xfns.c (image_cache_refcount):
16559 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
16560 on typical 64-bit hosts.

16571 since parse_image_check makes sure they fit into int.
16572 (png_load, gif_load, svg_load_image):
16573 Prefer int to unsigned where either will do.
16574 (tiff_handler): New function, combining the cores of the
16575 old tiff_error_handler and tiff_warning_handler.
16576 This function is rewritten to use vsnprintf and thereby avoid
16577 stack buffer overflows. It uses only the features of vsnprintf
16578 that are common to both POSIX and native Microsoft.
16579 (tiff_error_handler, tiff_warning_handler): Use it.
16580 (tiff_load, gif_load, imagemagick_load_image):
16581 Don't assume :index value fits in 'int'.
16582 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16583 (imagemagick_load_image): Check that crop parameters fit into
16584 the integer types that MagickCropImage accepts. Don't assume
16585 Vimagemagick_render_type has a nonnegative value. Don't assume
16586 size_t fits in 'long'.
16587 (gs_load): Use printmax_t to print the widest integers possible.
16588 Check for integer overflow when computing image height and width.
16590 2011-08-26 Eli Zaretskii <eliz@gnu.org>
16592 * xdisp.c (redisplay_window): Don't force window start if point

16597 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
16598 the display spec is of the form `(space ...)'.
16599 (handle_display_spec): Return the value returned by
16600 handle_single_display_spec, not just 1 or zero.
16601 (handle_single_display_spec): If the display spec is of the form
16602 `(space ...)', and specifies display in the text area, return 2
16604 (try_cursor_movement): Check for the need to scroll more
16605 accurately, and prefer exact match for point under bidi.
16606 Don't advance `row' beyond the last row of the window.
16608 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
16609 into disp_prop; all users changed.
16611 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
16612 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
16613 for the text covered by the display property.

16623 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
16624 buffers, return left-to-right.
16625 (set_cursor_from_row): Consider candidate row a win if its glyph
16626 represents a newline and point is on that newline. Fixes cursor
16627 positioning on the newline at EOL of R2L text within L2R
16628 paragraph, and vice versa.
16629 (try_cursor_movement): Check continued rows, in addition to
16630 continuation rows. Fixes unwarranted scroll when point enters a
16631 continued line of R2L text within an L2R paragraph, or vice versa.
16632 (cursor_row_p): Consider the case of point being equal to
16633 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
16634 from the end of a short line to the beginning of a continued line
16635 of R2L text within L2R paragraph.
16636 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
16637 composed characters.

16652 2011-08-22 Kenichi Handa <handa@m17n.org>
16654 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
16655 extra slot even if the purpose is char-code-property-table.
16657 2011-08-23 Eli Zaretskii <eliz@gnu.org>
16659 * xdisp.c (redisplay_window): When computing centering_position,
16660 account for the height of the header line. (Bug#8874)
16662 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16663 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16664 candidate is selected by the mouse, and that candidate has a
16665 composed character under the mouse.
16667 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16668 coordinates reported by pos-visible-in-window-p for a composed
16669 character in column zero.
16671 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
16673 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
16675 2011-08-22 Eli Zaretskii <eliz@gnu.org>
16677 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
16678 consider it a hit if to_charpos is anywhere in the range of the
16679 composed buffer positions.
16681 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16683 * image.c (gif_load): Don't assume that each subimage has the same
16684 dimensions as the base image. Handle disposal method that is
16685 "undefined" by the gif spec (Bug#9335).
16687 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
16689 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
16690 (Fcondition_case): Document `debug' symbol in error handler.
16692 2011-08-19 Eli Zaretskii <eliz@gnu.org>
16694 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
16695 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
16696 from an Org mode buffer to a Speedbar frame.
16698 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
16699 a composition, take its buffer position from IT->cmp_it.charpos.
16700 Fixes cursor positioning at the beginning of a line that begins
16701 with a composed character.
16703 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16705 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16706 character bidirectional type, use STRONG_L instead. Fixes crashes
16707 in a buffer produced by `describe-categories'.
16709 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16710 members before the level stack, so they would be saved and
16711 restored when copying iterator state. Fixes incorrect reordering
16712 around TABs covered by display properties.
16714 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
16716 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

16721 (internal_condition_case_2, internal_condition_case_n):
16722 Remove unnecessary aborts (Bug#9081).
16724 2011-08-17 Eli Zaretskii <eliz@gnu.org>
16726 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
16727 has no `load' handler, try opening the file locally. (Bug#9311)
16729 2011-08-16 Ken Brown <kbrown@cornell.edu>
16731 * gmalloc.c: Expand comment.
16733 2011-08-16 Eli Zaretskii <eliz@gnu.org>
16735 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
16736 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
16738 2011-08-16 Ken Brown <kbrown@cornell.edu>
16740 Fix memory allocation problems in Cygwin build (Bug#9273).
16742 * unexcw.c ( __malloc_initialized): Declare external variable.
16743 (fixup_executable): Force the dumped emacs to reinitialize malloc.
16745 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
16747 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

16775 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
16776 coordinates of the iterator when restoring from ppos_it.
16779 2011-08-14 Kenichi Handa <handa@m17n.org>
16781 * process.c (create_process): Call setup_process_coding_systems
16782 after the pid of the process is set to -1 (Bug#8162).
16784 2011-08-14 Eli Zaretskii <eliz@gnu.org>
16786 * xdisp.c (move_it_in_display_line_to): Don't invoke
16787 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16788 ppos_it. Fixes vertical cursor motion when line beginning is
16789 covered by an image. (Bug#9296)
16791 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
16793 * nsterm.h (ns_run_ascript): Declare.

16796 * nsfns.m (as_script, as_result, as_status): New static variables.
16797 (ns_run_ascript): New function.
16798 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
16799 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
16800 the event loop. Get status from as_status (Bug#7276).
16802 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16803 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16804 the event loop (Bug#7276).
16806 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
16808 * gnutls.c (QCgnutls_bootprop_priority)

16829 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
16830 (Fnetwork_interface_list): Allocate in increments of bytes instead
16831 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16832 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16834 (struct ifflag_def): notrailers is smart on OSX.
16835 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16836 Get hardware address with getifaddrs if available.
16838 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16840 * xdisp.c (iterate_out_of_display_property): xassert that
16841 IT->position is set to within IT->object's boundaries. Break from
16842 the loop as soon as EOB is reached; avoids infloops in redisplay
16843 when IT->position is set up wrongly due to some bug.
16844 Set IT->current to match the bidi iterator unconditionally.
16845 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16846 entry. Force push_it to save on the stack the current
16847 buffer/string position, to be restored by pop_it. Fix flags in
16848 the iterator structure wrt the object coming from a display
16849 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16850 properties. (Bug#9284)
16852 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16854 * fontset.c (fontset_get_font_group): Add proper type checks.

16860 and LC_VERSION_MIN_MACOSX.
16861 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
16862 (dump_it) [LC_FUNCTION_STARTS]: Use it.
16864 2011-08-08 Eli Zaretskii <eliz@gnu.org>
16866 * xdisp.c (forward_to_next_line_start): Allow to use the
16867 no-display-properties-and-no-overlays under bidi display.
16868 Set disp_pos in the bidi iterator to avoid searches for display
16869 properties and overlays.
16871 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16873 * editfns.c (Fset_time_zone_rule): Document relationship with the
16876 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
16877 the font entity extracted from the cache (Bug#8109).
16879 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
16881 * composite.c (autocmp_chars): Don't reset point. That is done by
16882 restore_point_unwind (Bug#5984).
16884 2011-08-07 Juri Linkov <juri@jurta.org>
16886 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16887 to show the arg `TIME' instead of `TIMEVAL'.
16889 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16891 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16892 display property strides EOL and includes a newline, as in
16893 longlines-mode. (Bug#9254)
16894 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16895 word-wrap under bidirectional display. (Bug#9224)
16897 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16898 is non-zero, even if the data buffer is NULL. Fixes a crash in
16899 vertical-motion with longlines-mode. (Bug#9254)
16901 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16903 * bidi.c <bidi_cache_total_alloc>: Now static.
16904 (bidi_initialize): Initialize bidi_cache_total_alloc.
16906 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16909 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16910 amount allocated this far in `bidi_cache_total_alloc'.
16911 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16912 non-zero, only free the data buffer without restoring the cache
16913 contents. All callers changed.
16915 * dispextern.h (bidi_unshelve_cache): Update prototype.
16917 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16918 (move_it_in_display_line, move_it_to)
16919 (move_it_vertically_backward, move_it_by_lines): Replace the call
16920 to xfree to an equivalent call to bidi_unshelve_cache.
16921 (move_it_in_display_line_to): Fix logic of returning
16922 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16924 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16926 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16927 came from a string character with a `cursor' property. (Bug#9229)
16929 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16931 * Makefile.in (LIB_PTHREAD): New variable.
16932 (LIBES): Add LIB_PTHREAD (Bug#9216).
16934 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
16935 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
16937 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
16939 * regex.c (re_iswctype): Remove some redundant boolean conversions.
16941 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16943 * xterm.c (x_find_topmost_parent): New function.
16944 (x_set_frame_alpha): Find topmost parent window with
16945 x_find_topmost_parent and set the property there also (bug#9181).
16946 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16948 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16950 * callproc.c (Fcall_process): Avoid vfork clobbering
16951 the local vars buffer, coding_systems, current_dir.
16953 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
16955 * keymap.c (Fmake_composed_keymap): Move to subr.el.
16957 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
16959 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16960 so that it is not optimized away.
16962 * xdisp.c (compute_display_string_pos): Remove unused local.
16964 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16966 Fix slow cursor motion and scrolling in large buffers with
16967 selective display, like Org Mode buffers. (Bug#9218)
16969 * dispextern.h (struct bidi_it): New member disp_prop_p.
16971 * xdisp.c: Remove one-slot cache of display string positions.
16972 (compute_display_string_pos): Accept an additional argument
16973 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16974 for a display string or property. If found, set DISP_PROP_P
16977 * bidi.c (bidi_fetch_char): Accept an additional argument
16978 DISP_PROP_P, and pass it to compute_display_string_pos.
16979 Only handle text covered by a display string if DISP_PROP_P is returned
16980 non-zero. All callers of bidi_fetch_char changed.
16982 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16984 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16986 2010-12-03 Don March <don@ohspite.net>
16988 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16989 last character M-[char] is translated to ESC [char] (bug#7541).
16991 2011-08-02 Kenichi Handa <handa@m17n.org>
16993 * lisp.h (uniprop_table): Extern it.
16995 * chartab.c (uniprop_table): Make it non-static.
16997 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16999 * xdisp.c (forward_to_next_line_start): Accept additional argument
17000 BIDI_IT_PREV, and store into it the state of the bidi iterator had
17002 (reseat_at_next_visible_line_start): Use the bidi iterator state
17003 returned by forward_to_next_line_start to restore the state of
17004 it->bidi_it after backing up to previous newline. (Bug#9212)
17006 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
17008 * regex.c (re_comp): Protoize.
17009 (re_exec): Fix return type.
17010 (regexec): Fix type of `ret'. (Bug#9203)
17012 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17014 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
17015 This is needed if max-image-size is a floating-point number.
17017 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17019 * print.c (print_object): Print empty symbol as ##.
17021 * lread.c (read1): Read ## as empty symbol.
17023 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17025 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
17026 setting frame foreground color (Bug#9175).
17027 (x_set_background_color): Likewise.
17029 * nsmenu.m (-setText): Size tooltip dimensions precisely to
17030 contents (Bug#9176).
17031 (EmacsTooltip -init): Remove bezels and add shadows to
17034 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
17035 or scroll bar (Bug#8470).
17037 * nsfont.m (nsfont_open): Remove assignment to voffset and
17038 unnecessary vars hshink, expand, hd, full_height, min_height.
17039 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
17041 * nsterm.h (nsfont_info): Remove voffset field.
17043 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17045 Implement strike-through and overline on NextStep (Bug#8863).
17047 * nsfont.m (nsfont_open): Use underline position provided by font,
17048 instead of hard-coded value of 2.
17049 (nsfont_draw): Call ns_draw_text_decoration instead.
17051 * nsterm.h: Add declaration for ns_draw_text_decoration.
17053 * nsterm.m (ns_draw_text_decoration): New function for drawing
17054 underline, overline, and strike-through.
17055 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
17056 ns_draw_text_decoration. Change treatment of cursor drawing to
17057 accommodate underlining, etc.
17059 2011-07-28 Eli Zaretskii <eliz@gnu.org>
17061 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
17064 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17066 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
17067 Without this fix, if a signal arrives just after memory fills up,
17068 'malloc' might be invoked reentrantly.
17070 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
17071 In other words, assume that every image size is allowed, on non-X
17072 hosts. This assumption is probably wrong, but it lets Emacs compile.
17074 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17076 * regex.c (re_iswctype): Convert return values to boolean.
17078 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
17080 * xdisp.c (compute_display_string_pos): Don't use cached display
17081 string position if the buffer had its restriction changed.
17084 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17086 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17088 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17090 Integer signedness and overflow and related fixes. (Bug#9079)
17092 * bidi.c: Integer size and overflow fixes.
17093 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
17094 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
17095 (bidi_cache_find_level_change, bidi_cache_ensure_space)
17096 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
17097 (bidi_find_other_level_edge):
17098 Use ptrdiff_t instead of EMACS_INT where either will do.
17099 This works better on 32-bit hosts configured --with-wide-int.
17100 (bidi_cache_ensure_space): Check for size-calculation overflow.
17101 Use % rather than repeated addition, for better worst-case speed.
17102 Don't set bidi_cache_size until after xrealloc returns, because it
17104 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
17105 (bidi_cache_ensure_space): Also check that the bidi cache size
17106 does not exceed that of the largest Lisp string or buffer. See Eli
17107 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
17109 * alloc.c (__malloc_size_t): Remove.
17110 All uses replaced by size_t. See Andreas Schwab's note
17111 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
17113 * image.c: Improve checking for integer overflow.
17114 (check_image_size): Assume that f is nonnull, since
17115 it is always nonnull in practice. This is one less thing to
17116 worry about when checking for integer overflow later.
17117 (x_check_image_size): New function, which checks for integer
17118 overflow issues inside X.
17119 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
17120 This removes the need for a memory_full check.
17121 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
17122 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
17123 (xbm_read_bitmap_data): Change locals back to 'int', since
17124 their values must fit in 'int'.
17125 (xpm_load_image, png_load, tiff_load):
17126 Invoke x_create_x_image_and_pixmap earlier,
17127 to avoid much needless work if the image is too large.
17128 (tiff_load): Treat overly large images as if
17129 x_create_x_image_and_pixmap failed, not as malloc failures.
17130 (gs_load): Use x_check_image_size.
17132 * gtkutil.c: Omit integer casts.
17133 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
17134 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
17136 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
17138 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
17139 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
17140 would wrongly return t on a 64-bit host.
17142 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
17143 The plain *_OVERFLOW macros run afoul of GCC bug 49705
17144 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
17145 and therefore cause GCC to emit a bogus diagnostic in some cases.
17147 * image.c: Integer signedness and overflow and related fixes.
17148 This is not an exhaustive set of fixes, but it's time to
17149 record what I've got.
17150 (lookup_pixel_color, check_image_size): Remove redundant decls.
17151 (check_image_size): Don't assume that arbitrary EMACS_INT values
17152 fit in 'int', or that arbitrary 'double' values fit in 'int'.
17153 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
17154 (tiff_load, imagemagick_load_image):
17155 Check for overflow in size calculations.
17156 (x_create_x_image_and_pixmap): Remove unnecessary test for
17157 xmalloc returning NULL; that can't happen.
17158 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
17159 (xpm_color_bucket): Use better integer hashing function.
17160 (xpm_cache_color): Don't possibly over-allocate memory.
17161 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
17162 (gif_memory_source):
17163 Use ptrdiff_t, not int or size_t, to record sizes.
17164 (png_load): Don't assume values greater than 2**31 fit in 'int'.
17165 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
17166 either works, as we prefer signed integers.
17167 (tiff_read_from_memory, tiff_write_from_memory):
17168 Return tsize_t, not size_t, since that's what the TIFF API wants.
17169 (tiff_read_from_memory): Don't fail simply because the read would
17170 go past EOF; instead, return a short read.
17171 (tiff_load): Omit no-longer-needed casts.
17172 (Fimagemagick_types): Don't assume size fits into 'int'.
17174 Improve hashing quality when configured --with-wide-int.
17175 * fns.c (hash_string): New function, taken from sxhash_string.
17176 Do not discard information about ASCII character case; this
17177 discarding is no longer needed.
17178 (sxhash-string): Use it. Change sig to match it. Caller changed.
17179 * lisp.h: Declare it.
17180 * lread.c (hash_string): Remove, since we now use fns.c's version.
17181 The fns.c version returns a wider integer if --with-wide-int is
17182 specified, so this should help the quality of the hashing a bit.
17184 * emacs.c: Integer overflow minor fix.
17185 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
17186 Define only if GNU_LINUX.
17187 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
17189 * dispnew.c: Integer signedness and overflow fixes.
17190 Remove unnecessary forward decls, that were a maintenance hassle.
17191 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
17193 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
17194 (scrolling_window): Use ptrdiff_t, not int, for byte count.
17195 (prepare_desired_row, line_draw_cost):
17196 Use int, not unsigned, where either works.
17197 (save_current_matrix, restore_current_matrix):
17198 Use ptrdiff_t, not size_t, where either works.
17199 (init_display): Check for overflow more accurately, and without
17200 relying on undefined behavior.
17202 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
17203 Remove, replacing with the new symbols in lisp.h. All uses changed.
17204 * fileio.c (make_temp_name):
17205 * filelock.c (lock_file_1, lock_file):
17206 * xdisp.c (message_dolog):
17207 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
17208 Use pMd etc. instead.
17209 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
17210 replacing the pWIDE etc. symbols removed from editfns.c.
17212 * keyboard.h (num_input_events): Now uintmax_t.
17213 This is (very slightly) less likely to mess up due to wraparound.
17216 * buffer.c: Integer signedness fixes.
17217 (alloc_buffer_text, enlarge_buffer_text):
17218 Use ptrdiff_t rather than size_t when either will do, as we prefer
17221 * alloc.c: Integer signedness and overflow fixes.
17222 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
17223 (__malloc_size_t): Default to size_t, not to int.
17224 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
17225 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17226 Prefer ptrdiff_t to size_t when either would do, as we prefer
17228 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17229 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17230 Now const. Initialize with values that are in range even if char
17232 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17233 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17234 These functions do the right thing with sizes > 2**32.
17235 (check_depth): Now ptrdiff_t, not int.
17236 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17237 Adjust to new way of storing sizes. Check for size overflow bugs
17239 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17240 slightly wrong anyway, as it missed one instance of
17241 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17242 (refill_memory_reserve): Omit needless cast to size_t.
17243 (mark_object_loop_halt): Mark as externally visible.
17245 * xselect.c: Integer signedness and overflow fixes.
17246 (Fx_register_dnd_atom, x_handle_dnd_message):
17247 Use ptrdiff_t, not size_t, since we prefer signed.
17248 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17249 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17250 x_dnd_atoms_size and x_dnd_atoms_length.
17252 * doprnt.c: Prefer signed to unsigned when either works.
17254 * doprnt.c (doprnt):
17256 * xdisp.c (vmessage):
17257 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17258 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17259 prefer signed arithmetic to avoid comparison confusion.
17260 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17261 but is a bit tricky.
17263 Assume freestanding C89 headers, string.h, stdlib.h.
17264 * data.c, doprnt.c, floatfns.c, print.c:
17265 Include float.h unconditionally.
17266 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17267 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17268 * regex.c: Likewise for stddef.h, string.h.
17269 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17270 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17271 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17272 (STDC_HEADERS): Remove obsolete defines.
17273 * sysdep.c: Include limits.h unconditionally.
17275 Assume support for memcmp, memcpy, memmove, memset.
17276 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17277 * regex.c (memcmp, memcpy):
17278 Remove; we assume C89 now.
17280 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17281 (__malloc_safe_bcopy): Remove; no longer needed.
17283 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17284 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17285 well either way, and we prefer signed to unsigned.
17287 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17289 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17290 closes the connection while we're reading (bug#9182).
17292 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17294 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17295 are specified (Bug#9168).
17297 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17299 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17300 Found by GCC static checking and --with-wide-int on a 32-bit host.
17302 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17304 * xdisp.c (compute_display_string_pos): Fix logic of caching
17305 previous display string position. Initialize cached_prev_pos to
17306 -1. Fixes slow-down at the beginning of a buffer.
17308 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17310 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17311 for attrs[LFACE_FONTSET_INDEX].
17313 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17315 * xml.c (parse_region): Remove unused local
17316 that was recently introduced.
17318 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17320 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17321 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17323 * xdisp.c (move_it_in_display_line_to): Record the best matching
17324 position for TO_CHARPOS while scanning the line, and restore it on
17325 exit if none of the characters scanned was an exact match.
17326 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17327 when exact match is impossible due to invisible text, and the
17328 lines are truncated.
17330 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17332 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17335 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17337 Fix a significant slow-down of cursor motion with C-n, C-p,
17338 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17339 auto-repeat under bidi redisplay in fontified buffers.
17340 * xdisp.c (compute_stop_pos_backwards): New function.
17341 (next_element_from_buffer): Call compute_stop_pos_backwards to
17342 find a suitable prev_stop when we find ourselves before
17344 (reseat): Don't look for prev_stop, as that could mean a very long
17346 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17347 <cached_disp_overlay_modiff>: Cache for last found display string
17349 (compute_display_string_pos): Return the cached position if asked
17350 about the same buffer in the same area of character positions, and
17351 the buffer wasn't changed since the time the display string
17352 position was cached.
17354 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17356 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17357 is an integer, which is important for empty lines. (Bug#9149)
17359 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17361 * frame.c (Fmodify_frame_parameters): In tty case, update the
17362 default face if necessary (Bug#4238).
17364 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17366 * editfns.c (Fstring_to_char): No need to explain what a character
17367 is in the docstring (Bug#6576).
17369 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17371 * xml.c (parse_region): Make sure we always return a tree.
17373 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17375 * xml.c (parse_region): If a document contains only comments,
17378 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17380 * xml.c (make_dom): Return comments, too.
17382 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17385 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17386 and the surrounding thread.
17387 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17388 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17389 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17391 * s/openbsd.h (BROKEN_SIGIO): Define.
17392 * unexelf.c (unexec) [__OpenBSD__]:
17393 Don't update the .mdebug section of the Alpha COFF symbol table.
17395 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17397 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17400 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17402 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17403 This fixes some race conditions on the permissions of any newly
17406 * alloc.c (valid_pointer_p): Use pipe, not open.
17407 This fixes some permissions issues when debugging.
17409 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17410 If fchown fails to set both uid and gid, try to set just gid,
17411 as that is sometimes allowed. Adjust the file's mode to eliminate
17412 setuid or setgid bits that are inappropriate if fchown fails.
17414 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17416 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

17428 symbol character follows.
17430 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17432 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17433 This works around a problem with the previous change to Fcopy_file.
17434 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17435 and without this change, GCC might complain about discarding
17436 fchown's return value.
17438 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17440 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17442 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17444 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17446 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17448 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17449 it's used from the C level.
17451 * process.c: Use the same condition for POLL_FOR_INPUT in both
17452 keyboard.c and process.c (bug#1858).
17454 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17456 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17457 (Fgnutls_boot): Use it.

17461 * doc.c (Fsubstitute_command_keys): Revert last change.
17463 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17465 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17466 quotes the next character, and doesn't affect other longer
17467 sequences (bug#8935).
17469 * lread.c (syms_of_lread): Clarify that is isn't only
17470 `eval-buffer' and `eval-defun' that's affected by
17471 `lexical-binding' (bug#8460).
17473 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17475 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17476 bidi redisplay when a line includes both an image and is truncated.
17478 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17480 Fix minor problems found by static checking.
17481 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17482 (elsz): Now a signed constant, not a size_t var. We prefer signed
17483 types to unsigned, to avoid integer comparison confusion. Without
17484 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17485 "cannot optimize loop, the loop counter may overflow", a symptom
17487 * indent.c (Fvertical_motion): Mark locals as initialized.
17488 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17490 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

17513 buffer position was specified. Initialize paragraph_embedding to
17515 (reseat_to_string): Initialize the bidi iterator.
17516 (display_string): If we need to ignore text properties of
17517 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17518 original value of -1 will not work with bidi.)
17519 (compute_display_string_pos): First arg is now struct
17520 `text_pos *'; all callers changed. Support display properties on
17522 (compute_display_string_end): Support display properties on Lisp
17524 (init_iterator, reseat_1, reseat_to_string): Initialize the
17525 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
17526 when iterating on a string not from display properties).
17527 (compute_display_string_pos, compute_display_string_end):
17528 Fix calculation of the object to scan. Fixes an error when using
17530 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
17531 base_level_stop; instead, set base_level_stop to BEGV.
17532 Fixes crashes in vertical-motion.
17533 (next_element_from_buffer): Improve commentary for when
17534 the iterator is before prev_stop.
17535 (init_iterator): Initialize bidi_p from the default value of
17536 bidi-display-reordering, not from buffer-local value. Use the
17537 buffer-local value only if initializing for buffer iteration.
17538 (handle_invisible_prop): Support invisible properties on strings
17539 that are being bidi-reordered.
17540 (set_iterator_to_next): Support bidi reordering of C strings and

17547 (init_iterator): Don't initialize it->bidi_p for strings
17549 (reseat_to_string): Initialize it->bidi_p for strings here.

17558 parts of next_element_from_buffer, next_element_from_string, and
17559 next_element_from_c_string.
17560 (tool_bar_lines_needed, redisplay_tool_bar)
17561 (display_menu_bar): Force left-to-right direction. Add a FIXME
17562 comment for making that be controlled by a user option.

17571 (get_overlay_strings_1, push_display_prop): Set up the bidi
17572 iterator for displaying display or overlay strings.
17573 (forward_to_next_line_start): Don't use the shortcut if
17575 (back_to_previous_visible_line_start): If handle_display_prop
17576 pushed the iterator stack, restore the internal state of the bidi
17577 iterator by calling bidi_pop_it same number of times.
17578 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
17579 and we are bidi-iterating, don't decrement the iterator position;
17580 instead, set the first_elt flag in the bidi iterator, to produce
17582 (reseat_1): Remove redundant setting of string_from_display_prop_p.
17583 (push_display_prop): xassert that we are iterating a buffer.
17584 (push_it, pop_it): Save and restore paragraph_embedding member.
17585 (handle_single_display_spec, next_overlay_string)
17586 (get_overlay_strings_1, reseat_1, reseat_to_string)
17587 (push_display_prop): Set up the `unibyte' member of bidi_it.string
17588 correctly. Don't assume unibyte strings are not bidi-reordered.
17589 (compute_display_string_pos)
17590 (compute_display_string_end): Fix handling the case of C string.

17596 popping after iteration over a string that came from a display
17597 property. Fix a typo in popping stretch info. Add an assertion
17598 for verifying that the iterator position is in sync with the bidi
17600 (handle_single_display_spec, get_overlay_strings_1)

17625 displayed in margins. (Bug#8133) (Bug#8867)
17626 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past

17629 Save and restore bidi cache.
17631 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.

17654 changed to -1 and -2, respectively.
17655 (bidi_char_at_pos): New function.
17656 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

17690 (struct iterator_stack_entry): New members bidi_p,
17691 paragraph_embedding, and from_disp_prop_p.

17739 Pass Qx_lost_selection_functions rather than
17740 Vx_lost_selection_functions to Frun_hook_with_args.
17742 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
17744 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
17745 The old code sometimes used this field without initializing it.
17747 * alloc.c (gc_sweep): Don't read past end of array.
17748 In theory, the old code could also have corrupted Emacs internals,
17749 though it'd be very unlikely.

17753 * character.c (Fcharacterp): Don't advertise optional ignored
17754 argument. (Bug#4026)

18012 (clone_per_buffer_values): Don't assume that
18013 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
18014 This isn't true in general, and it's particularly not true
18015 if Emacs is configured with --with-wide-int.
18016 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
18017 New macros, used in the buffer.c change.

18053 Random fixes. E.g., (random) never returned negative values.
18054 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
18055 subseconds part to the entropy, as that's a bit more random.
18056 Prefer signed to unsigned, since the signedness doesn't matter and
18057 in general we prefer signed. When given a limit, use a
18058 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
18059 latter isn't right if USE_2_TAGS_FOR_INTS.
18060 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
18061 not 0..VALMASK. Don't discard "excess" bits that random () returns.
18063 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
18065 * textprop.c (text_property_stickiness):
18066 Obey Vtext_property_default_nonsticky.

18073 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
18074 This is more efficient than Ffile_directory_p and avoids a minor race.
18076 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
18078 * buffer.c (Foverlay_put): Say what the return value is
18081 * fileio.c (barf_or_query_if_file_exists): Check first if the file
18082 is a directory before asking whether to use the file name
18084 (barf_or_query_if_file_exists): Make the "File is a directory"
18085 error be more correct.
18087 * fns.c (Frequire): Remove the mention of the .gz files, since
18088 that's installation-specific, but keep the mention of
18089 `get-load-suffixes'.
18091 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
18093 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

18101 Qgnutls_bootprop_verify_error (which is no longer used).
18103 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
18104 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
18105 Also (re)move comments that are misplaced or no longer relevant.
18107 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
18109 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

18130 leave any prefix arg for the up event (Bug#1586).
18132 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
18134 * lread.c (syms_of_lread): Mention single symbols defined by
18135 `defvar' or `defconst' (bug#7154).
18137 * fns.c (Frequire): Mention .el.gz files (bug#7314).
18138 (Frequire): Mention get-load-suffixes.

18166 minibuffer-local-must-match-map, and
18167 minibuffer-local-filename-must-match-map to Elisp.
18168 (syms_of_keymap): Defsubr make-composed-keymap.
18169 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

18198 (xgselect_initialize): Ditto.
18200 * process.c: Add defined (HAVE_GSETTINGS) for xgselect.h

18204 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
18206 * eval.c (struct backtrace): Simplify and port the data structure.
18207 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
18208 signed bit field, as this assumption is not portable and it makes
18209 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
18210 "char debug_on_exit : 1" as this is not portable either; instead,
18211 use the portable "unsigned int debug_on_exit : 1". Remove unused
18212 member evalargs. Remove obsolete comments about cc bombing out.
18214 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

18380 * print.c (printchar, strout): Check for string overflow.
18381 (PRINTPREPARE, printchar, strout):
18382 Don't set size unless allocation succeeds.
18384 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
18385 for sizes. Check for string overflow more accurately.
18386 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
18388 * macros.c: Integer and buffer overflow fixes.
18389 * keyboard.h (struct keyboard.kbd_macro_bufsize):
18390 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

18396 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
18398 * lread.c: Integer overflow fixes.
18399 (read_integer): Radix is now EMACS_INT, not int,
18400 to improve quality of diagnostics for out-of-range radices.
18401 Calculate buffer size correctly for out-of-range radices.
18402 (read1): Check for integer overflow in radices, and in
18403 read-circle numbers.
18404 (read_escape): Avoid int overflow.
18405 (Fload, openp, read_buffer_size, read1)
18406 (substitute_object_recurse, read_vector, read_list, map_obarray):

18422 2011-06-22 Leo Liu <sdl.web@gmail.com>
18424 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
18425 Move to minibuffer.el.
18427 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18429 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
18430 The following patches are for when GLYPH_DEBUG && !XASSERT.
18431 * dispextern.h (trace_redisplay_p, dump_glyph_string):
18432 * dispnew.c (flush_stdout):
18433 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
18434 Mark as externally visible.
18435 * dispnew.c (check_window_matrix_pointers): Now static.
18436 * dispnew.c (window_to_frame_vpos):
18437 * xfns.c (unwind_create_frame):
18438 * xterm.c (x_check_font): Remove unused local.
18439 * scroll.c (CHECK_BOUNDS):
18440 * xfaces.c (cache_fache): Rename local to avoid shadowing.
18441 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
18442 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
18443 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
18444 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
18446 (debug_method_add): Use va_list and vsprintf rather than relying
18447 on undefined behavior with wrong number of arguments.
18448 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18449 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18450 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18451 since we're not interested in debugging glyphs with old libraries.
18452 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18453 GCC 4.6.0's static checking.
18455 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18457 Integer overflow and signedness fixes (Bug#8873).

18473 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
18474 (.bitmaps_last, struct x_output.icon_bitmap):
18475 Use ptrdiff_t, not int, for bitmap indexes.
18476 (x_allocate_bitmap_record): Check for size overflow.
18477 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
18479 Use ptrdiff_t, not int, for overlay counts.
18480 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
18481 * editfns.c (overlays_around, get_pos_property):
18482 * textprop.c (get_char_property_and_overlay):
18483 * xdisp.c (next_overlay_change, note_mouse_highlight):
18484 * xfaces.c (face_at_buffer_position):
18485 * buffer.c (OVERLAY_COUNT_MAX): New macro.
18486 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
18487 (Fnext_overlay_change, Fprevious_overlay_change)
18488 (mouse_face_overlay_overlaps, Foverlays_in):
18489 Use ptrdiff_t, not int, for sizes.
18490 (overlays_at, overlays_in): Check for size-calculation overflow.
18492 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18494 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18495 (x_session_initialize): Do not assume string length fits in int.
18497 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18498 This is unlikely, but can occur if DPI is outlandish.
18500 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
18501 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
18503 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
18504 * xrdb.c (magic_file_p, search_magic_path):
18505 Omit last arg SUFFIX; it was always 0. All callers changed.
18506 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18508 * xfont.c (xfont_match): Avoid need for strlen.
18510 * xfns.c: Don't assume strlen fits in int.

18513 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18514 not unsigned long, as we prefer signed integers. All callers changed.
18515 Detect integer overflow in repeat count.
18516 (message_dolog): Don't assume print length fits in 39 bytes.
18517 (display_mode_element): Don't assume strlen fits in int.
18519 * termcap.c: Don't assume sizes fit in int and never overflow.
18520 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
18521 (gobble_line): Check for size-calculation overflow.
18523 * minibuf.c (Fread_buffer):
18524 * lread.c (intern, intern_c_string):
18525 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

18538 * filelock.c: Fix some buffer overrun and integer overflow issues.
18539 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18540 Reformulate so as not to need the command string.
18541 Invoke gzip -cd rather than gunzip, as it's more portable.
18542 (lock_info_type, lock_file_1, lock_file):
18543 Don't assume pid_t and time_t fit in unsigned long.
18544 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18545 (current_lock_owner): Prefer signed type for sizes.
18546 Use memcpy, not strncpy, where memcpy is what is really wanted.
18547 Don't assume (via atoi) that time_t and pid_t fit in int.
18548 Check for time_t and/or pid_t out of range, e.g., via a network share.
18549 Don't alloca where an auto var works fine.
18551 * fileio.c: Fix some integer overflow issues.
18552 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18553 Don't assume string length fits in int.
18554 (directory_file_name): Don't assume string length fits in long.
18555 (make_temp_name): Don't assume pid fits in int, or that its print
18556 length is less than 20.

18575 (Fgetenv_internal):
18576 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18578 * lread.c (invalid_syntax): Omit length argument.
18579 All uses changed. This doesn't fix a bug, but it simplifies the
18580 code away from its former Hollerith-constant appearance, and it's
18581 one less 'int' to worry about when looking at integer-overflow issues.
18582 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18584 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18585 This didn't break anything, but it didn't help either.
18586 It's confusing to put a bogus integer in a place where the actual
18587 value does not matter.
18588 (LIST_END_P): Remove unused macro and its bogus comment.
18589 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18591 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18592 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18594 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18595 We prefer signed types, and the value cannot exceed the EMACS_INT
18596 range anyway (because otherwise the length would not be representable).
18597 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18598 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18599 This avoids a GCC warning when WIDE_EMACS_INT.
18601 * indent.c (sane_tab_width): New function.
18602 (current_column, scan_for_column, Findent_to, position_indentation)
18603 (compute_motion): Use it. This is just for clarity.
18604 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18606 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
18608 * lisp.h (lint_assume): New macro.
18609 * composite.c (composition_gstring_put_cache):
18610 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18612 * editfns.c, insdel.c:
18613 Omit unnecessary forward decls, to simplify future changes.
18615 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18617 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18619 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18620 Use much-faster test for byte-length change.
18621 Don't assume string byte-length fits in 'int'.
18622 Check that character arg fits in 'int'.
18623 (mapcar1): Declare byte as byte, for clarity.
18625 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18627 * fns.c (concat): Catch string overflow earlier.
18628 Do not rely on integer wraparound.
18630 * dispextern.h (struct it.overlay_strings_charpos)
18631 (struct it.selective): Now EMACS_INT, not int.
18632 * xdisp.c (forward_to_next_line_start)
18633 (back_to_previous_visible_line_start)
18634 (reseat_at_next_visible_line_start, next_element_from_buffer):
18635 Don't arbitrarily truncate the value of 'selective' to int.
18637 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18639 * composite.c: Don't truncate sizes to 'int'.
18640 (composition_gstring_p, composition_reseat_it)
18641 (composition_adjust_point): Use EMACS_INT, not int.
18642 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18643 not EMACS_UINT, for indexes.
18645 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18647 * buffer.c: Include <verify.h>.
18648 (struct sortvec.priority, struct sortstr.priority):
18649 Now EMACS_INT, not int.
18650 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18651 (struct sortstr.size, record_overlay_string)
18652 (struct sortstrlist.size, struct sortlist.used):
18653 Don't truncate size to int.
18654 (record_overlay_string): Check for size-calculation overflow.
18655 (init_buffer_once): Check at compile-time, not run-time.
18657 2011-06-22 Jim Meyering <meyering@redhat.com>
18659 Don't leak an XBM-image-sized buffer
18660 * image.c (xbm_load): Free the image buffer after using it.
18662 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18665 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18666 that Sun C diagnosed.
18667 * fns.c (secure_hash): Fix pointer signedness issue.
18668 * intervals.c (static_offset_intervals): New function.
18669 (offset_intervals): Use it.
18671 2011-06-21 Leo Liu <sdl.web@gmail.com>
18674 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18677 * fns.c (secure_hash): Rename from crypto_hash_function and change
18678 the first arg to accept symbols.
18679 (Fsecure_hash): New primitive.
18680 (syms_of_fns): New symbols.
18682 2011-06-20 Deniz Dogan <deniz@dogan.se>
18684 * process.c (Fset_process_buffer): Clarify return value in
18687 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18689 * dispnew.c (add_window_display_history): Use BVAR.
18691 * xdisp.c (debug_method_add): Use BVAR.
18692 (check_window_end, dump_glyph_matrix, dump_glyph)
18693 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18695 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18698 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18699 check till after the cache is created in init_frame_faces.
18701 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18703 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18705 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18707 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18708 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18709 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18711 Improve buffer-overflow checking (Bug#8873).
18712 * fileio.c (Finsert_file_contents):
18713 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18714 Remove the old (too-loose) buffer overflow checks.
18715 They weren't needed, since make_gap checks for buffer overflow.
18716 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18717 The old code merely checked for Emacs fixnum overflow, and relied
18718 on undefined (wraparound) behavior. The new code avoids undefined
18719 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18721 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18722 Tune. Don't use wider integers than needed. Don't use alloca.
18723 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18725 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18727 * insdel.c, lisp.h (buffer_overflow): New function.
18728 (insert_from_buffer_1, replace_range, replace_range_2):
18729 * insdel.c (make_gap_larger):
18730 * editfns.c (Finsert_char):
18731 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18733 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18735 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18737 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18739 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18740 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18742 * fileio.c: Don't assume EMACS_INT fits in off_t.
18743 (emacs_lseek): New static function.
18744 (Finsert_file_contents, Fwrite_region): Use it.
18745 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18747 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18749 * fns.c: Don't overflow int when computing a list length.
18750 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18751 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18752 truncation on 64-bit hosts. Check for QUIT every
18753 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18754 faster and is responsive enough.
18755 (Flength): Report an error instead of overflowing an integer.
18756 (Fsafe_length): Return a float if the value is not representable
18757 as a fixnum. This shouldn't happen except in contrived situations.
18758 (Fnthcdr, Fsort): Don't assume list length fits in int.
18759 (Fcopy_sequence): Don't assume vector length fits in int.
18761 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18762 (header_size, word_size): New constants.
18763 (allocate_vectorlike): Don't check size overflow here.
18764 (allocate_vector): Check it here instead, since this is the only
18765 caller of allocate_vectorlike that could cause overflow.
18766 Check that the new vector's length is representable as a fixnum.
18768 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18769 The previous code was bogus. For example, next_almost_prime (32)
18770 returned 39, which is undesirable as it is a multiple of 3; and
18771 next_almost_prime (24) returned 25, which is a multiple of 5 so
18772 why was the code bothering to check for multiples of 7?
18774 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18776 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18778 Variadic C functions now count arguments with ptrdiff_t.
18779 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18780 Back then I didn't know that the Emacs coding style prefers signed int.
18781 Also, in the meantime I found a few more instances where arguments
18782 were being counted with int, which may truncate counts on 64-bit
18783 machines, or EMACS_INT, which may be unnecessarily wide.
18784 * lisp.h (struct Lisp_Subr.function.aMANY)
18785 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18786 Arg counts are now ptrdiff_t, not size_t.
18787 All variadic functions and their callers changed accordingly.
18788 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18789 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18790 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18791 * callint.c (Fcall_interactively): Check arg count for overflow,
18792 to avoid potential buffer overrun. Use signed char, not 'int',
18793 for 'varies' array, so that we needn't bother to check its size
18794 calculation for overflow.
18795 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18796 * eval.c (apply_lambda):
18797 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18798 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18799 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18801 * callint.c (Fcall_interactively): Don't use index var as event count.
18803 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18804 * mem-limits.h (SIZE): Remove; no longer used.
18806 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18808 Remove unnecessary casts.
18809 * xterm.c (x_term_init):
18810 * xfns.c (x_set_border_pixel):
18811 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18812 These aren't needed now that we assume ANSI C.
18814 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18815 It's more likely to cause problems (due to unsigned overflow)
18818 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18820 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18822 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18824 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18826 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18828 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18830 GLYPH_CODE_FACE returns EMACS_INT, not int.
18831 * dispextern.h (merge_faces):
18832 * xfaces.c (merge_faces):
18833 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18834 Don't assume EMACS_INT fits in int.
18836 * character.h (CHAR_VALID_P): Remove unused parameter.
18837 * fontset.c, lisp.h, xdisp.c: All uses changed.
18839 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18841 * fns.c (concat): Minor tuning based on overflow analysis.
18842 This doesn't fix any bugs. Use int to hold character, instead
18843 of constantly refetching from Emacs object. Use XFASTINT, not
18844 XINT, for value known to be a character. Don't bother comparing
18845 a single byte to 0400, as it's always less.
18847 * floatfns.c (Fexpt):
18848 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18850 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18853 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18855 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18856 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18857 incorrectly succeed when S was a string, because 4294967386 was
18858 truncated before it was used.
18860 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18861 Otherwise, an out-of-range integer could cause undefined behavior
18864 * composite.c: Use int, not EMACS_INT, for characters.
18865 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18866 EMACS_INT, for values that are known to be in character range.
18867 This doesn't fix any bugs but is the usual style inside Emacs and
18868 may generate better code on 32-bit machines.
18870 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18871 This is for reasons similar to the recent CHAR_STRING fix.
18872 * charset.c (Fencode_char): Check that character arg is actually
18873 a character. Pass an int to ENCODE_CHAR.
18874 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18875 wider than 'int', as a compile-time check to prevent future regressions
18878 * character.c (char_string): Remove unnecessary casts.
18880 Make sure a 64-bit char is never passed to CHAR_STRING.
18881 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18882 by silently ignoring the top 32 bits, allowing some values
18883 that were far too large to be valid characters.
18884 * character.h: Include <verify.h>.
18885 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18886 arguments are no wider than unsigned, as a compile-time check
18887 to prevent future regressions in this area.
18889 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18890 (Fsubst_char_in_region):
18892 * xdisp.c (decode_mode_spec_coding):
18893 Adjust to CHAR_STRING's new requirement.
18894 * editfns.c (Finsert_char, Fsubst_char_in_region):
18895 * fns.c (concat): Check that character args are actually
18896 characters. Without this test, these functions did the wrong
18897 thing with wildly out-of-range values on 64-bit hosts.
18899 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18900 These casts should not be needed on 32-bit hosts, either.
18901 * keyboard.c (read_char):
18902 * lread.c (Fload): Remove casts to unsigned.
18904 * lisp.h (UNSIGNED_CMP): New macro.
18905 This fixes comparison bugs on 64-bit hosts.
18906 (ASCII_CHAR_P): Use it.
18907 * casefiddle.c (casify_object):
18908 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18909 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18910 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18911 * dispextern.h (FACE_FROM_ID):
18912 * keyboard.c (read_char): Use UNSIGNED_CMP.
18914 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18915 not to EMACS_INT, to avoid GCC warning.
18917 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18919 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18920 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18921 isn't needed on 32-bit machines.
18923 * buffer.c (Fgenerate_new_buffer_name):
18924 Use EMACS_INT for count, not int.
18925 (advance_to_char_boundary): Return EMACS_INT, not int.
18927 * data.c (Qcompiled_function): Now static.
18929 * window.c (window_body_lines): Now static.
18931 * image.c (gif_load): Rename local to avoid shadowing.
18933 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18934 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18935 * alloc.c (make_save_value): Integer argument is now of type
18936 ptrdiff_t, not int.
18937 (mark_object): Use ptrdiff_t, not int.
18938 * lisp.h (pD): New macro.
18939 * print.c (print_object): Use it.
18941 * alloc.c: Use EMACS_INT, not int, to count objects.
18942 (total_conses, total_markers, total_symbols, total_vector_size)
18943 (total_free_conses, total_free_markers, total_free_symbols)
18944 (total_free_floats, total_floats, total_free_intervals)
18945 (total_intervals, total_strings, total_free_strings):
18946 Now EMACS_INT, not int. All uses changed.
18947 (Fgarbage_collect): Compute overall total using a double, so that
18948 integer overflow is less likely to be a problem. Check for overflow
18949 when converting back to an integer.
18950 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18951 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18952 These were 'int' variables that could overflow on 64-bit hosts;
18953 they were never used, so remove them instead of repairing them.
18954 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18955 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18956 Previously, this ceilinged at INT_MAX, but that doesn't work on
18958 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18960 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18961 (allocate_vectorlike): Check for ptrdiff_t overflow.
18962 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18963 when a (possibly-narrower) signed value would do just as well.
18964 We prefer using signed arithmetic, to avoid comparison confusion.
18966 * alloc.c: Catch some string size overflows that we were missing.
18967 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18968 for convenience in STRING_BYTES_MAX.
18969 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18970 The definition here is exact; the one in lisp.h was approximate.
18971 (allocate_string_data): Check for string overflow. This catches
18972 some instances we weren't catching before. Also, it catches
18973 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18974 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18975 and ptrdiff_t and EMACS_INT are both 64 bits.
18977 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18978 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18979 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18981 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18983 * alloc.c (Fmake_string): Check for out-of-range init.
18985 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18987 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18989 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18991 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18992 xg_get_default_scrollbar_width.
18994 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18995 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18996 (style_changed_cb): Call update_theme_scrollbar_width and call
18997 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18998 all frames (Bug#8505).
18999 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
19000 Call gtk_window_set_resizable if HAVE_GTK3.
19001 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
19002 and height if HAVE_GTK3 (Bug#8505).
19003 (scroll_bar_width_for_theme): New variable.
19004 (update_theme_scrollbar_width): New function.
19005 (xg_get_default_scrollbar_width): Move code to
19006 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
19007 (xg_initialize): Call update_theme_scrollbar_width.
19009 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
19011 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
19013 2011-06-12 Martin Rudalics <rudalics@gmx.at>
19015 * frame.c (make_frame): Call other_buffer_safely instead of
19018 * window.c (temp_output_buffer_show): Call display_buffer with
19019 second argument Vtemp_buffer_show_specifiers and reset latter
19020 immediately after the call.
19021 (Vtemp_buffer_show_specifiers): New variable.
19022 (auto_window_vscroll_p, next_screen_context_lines)
19023 (Vscroll_preserve_screen_position): Remove leading asterisks from
19026 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
19028 Fix minor problems found by GCC 4.6.0 static checking.
19029 * buffer.c (Qclone_number): Remove for now, as it's unused.
19030 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
19031 (record_buffer): Remove unused local.
19032 * frame.c (other_visible_frames, frame_buffer_list): Now static.
19033 (set_frame_buffer_list): Remove; unused.
19034 * frame.h (other_visible_frames): Remove decl.
19035 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
19036 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
19037 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
19039 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
19040 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
19041 Define only if HAVE_GPM.
19042 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
19043 (update_hints_inhibit): Remove; never set. All uses removed.
19044 * widgetprv.h (emacsFrameClassRec): Remove decl.
19045 * window.c (delete_deletable_window): Now returns void, since it
19046 wasn't returning anything.
19047 (compare_window_configurations): Remove unused locals.
19048 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
19049 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
19050 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
19051 the same widths as pointers. This follows up on the 2011-05-06 patch.
19052 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
19053 * xterm.h: Likewise.
19054 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
19056 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
19058 * makefile.w32-in: Update dependencies.
19059 (LISP_H): Add lib/intprops.h.
19061 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
19063 * image.c (gif_load): Add animation frame delay to the metadata.
19064 (syms_of_image): Use DEFSYM. New symbol `delay'.
19066 2011-06-11 Martin Rudalics <rudalics@gmx.at>
19068 * window.c (delete_deletable_window): Re-add.
19069 (Fset_window_configuration): Rewrite to handle dead buffers and
19070 consequently deletable windows.
19071 (window_tree, Fwindow_tree): Remove. Supply functionality in
19073 (compare_window_configurations): Simplify code.
19075 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
19077 * image.c (imagemagick_load_image): Fix type mismatch.
19078 (Fimagemagick_types): Likewise.
19080 * window.h (replace_buffer_in_windows): Declare.
19082 2011-06-11 Martin Rudalics <rudalics@gmx.at>
19084 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
19085 Qclone_number. Remove external declaration of Qdelete_window.
19086 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
19088 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
19089 Run Qbuffer_list_update_hook if allowed.
19090 (Fother_buffer): Rewrite doc-string. Major rewrite for new
19091 buffer list implementation.
19092 (other_buffer_safely): New function.
19093 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by

19546 Support character positions inside a run of characters covered by a
19548 (bidi_paragraph_init, bidi_resolve_explicit_1)
19549 (bidi_level_of_next_char): Call bidi_fetch_char and
19550 bidi_fetch_char_advance instead of FETCH_CHAR and
19551 FETCH_CHAR_ADVANCE.
19552 (bidi_init_it): Initialize new members.
19553 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
19555 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
19556 instead of using explicit *_CHAR codes.
19557 (bidi_resolve_explicit, bidi_resolve_weak):
19558 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
19559 bidirectional text is supported only in multibyte buffers.
19560 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
19561 it to initialize the frame_window_p member of struct bidi_it.
19562 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
19563 (bidi_resolve_explicit, bidi_resolve_weak)
19564 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
19565 bidi_it->nchars is non-positive.
19566 (bidi_level_of_next_char): Don't try to lookup the cache for the
19567 next/previous character if nothing is cached there yet, or if we
19568 were just reseat()'ed to a new position.
19570 * xdisp.c (set_cursor_from_row): Set start and stop points
19571 according to the row's direction when priming the loop that looks
19572 for the glyph on which to display cursor.
19573 (single_display_spec_intangible_p): Function deleted.
19574 (display_prop_intangible_p): Reimplement to call
19575 handle_display_spec instead of single_display_spec_intangible_p.
19576 Accept 3 additional arguments needed by handle_display_spec.
19577 This fixes incorrect cursor motion across display property with complex
19578 values: lists, `(when COND...)' forms, etc.
19579 (single_display_spec_string_p): Support property values that are
19580 lists with the argument STRING its top-level element.
19581 (display_prop_string_p): Fix the condition for processing a
19582 property that is a list to be consistent with handle_display_spec.
19583 (handle_display_spec): New function, refactored from the
19584 last portion of handle_display_prop.
19585 (compute_display_string_pos): Accept additional argument
19586 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
19587 value of a `display' property is a "replacing spec".
19588 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19589 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
19590 the display property, but just return a value indicating whether
19591 the display property will replace the characters it covers.
19592 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
19593 frame_window_p members of struct bidi_it.
19594 (compute_display_string_pos, compute_display_string_end):
19596 (push_it): Accept second argument POSITION, where pop_it should
19597 jump to continue iteration.
19598 (reseat_1): Initialize bidi_it.disp_pos.
19600 * keyboard.c (adjust_point_for_property): Adjust the call to
19601 display_prop_intangible_p to its new signature.
19603 * dispextern.h (struct bidi_it): New member frame_window_p.
19604 (bidi_init_it): Update prototypes.

19613 Malloc failure behavior now depends on size of allocation.
19614 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
19615 * lisp.h: Change signatures accordingly.
19616 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
19617 All callers changed. (Bug#8762)
19619 * gnutls.c: Use Emacs's memory allocators.
19620 Without this change, the gnutls library would invoke malloc etc.
19621 directly, which causes problems on non-SYNC_INPUT hosts, and which
19622 runs afoul of improving memory_full behavior. (Bug#8761)
19623 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19624 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19625 xfree instead of the default malloc, realloc, free.
19626 (Fgnutls_boot): No need to check for memory allocation failure,
19627 since xmalloc does that for us.
19629 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
19630 * category.c (hash_get_category_set):
19631 * ccl.c (ccl_driver):

19647 * lisp.h (struct Lisp_Hash_Table):
19648 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
19649 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
19650 for hashes and hash indexes, instead of 'unsigned' and 'int'.
19651 * alloc.c (allocate_vectorlike):
19652 Check for overflow in vector size calculations.
19653 * ccl.c (ccl_driver):
19654 Check for overflow when converting EMACS_INT to int.
19655 * fns.c, image.c: Remove unnecessary static decls that would otherwise
19656 need to be updated by these changes.
19657 * fns.c (make_hash_table, maybe_resize_hash_table):
19658 Check for integer overflow with large hash tables.
19659 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19660 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19661 (SXHASH_REDUCE): New macro.
19662 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19663 Use it instead of discarding useful hash info with large hash values.
19664 (sxhash_float): New function.
19665 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19666 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19667 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19668 Rewrite to use FIXNUM_BITS, as this simplifies things.
19669 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19670 Adjust signatures to match updated version of code.
19671 (consing_since_gc): Now EMACS_INT, since a single hash table can
19672 use more than INT_MAX bytes.
19674 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
19676 Make it possible to build with GCC-4.6+ -O2 -flto.
19678 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
19680 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
19682 * minibuf.c (get_minibuffer, read_minibuf_unwind):
19683 Call minibuffer-inactive-mode.
19685 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
19687 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
19688 Update dependencies.
19690 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19692 * data.c (init_data): Remove code for UTS, this system is not
19695 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19697 Don't force ./temacs to start in terminal mode.
19699 * frame.c (make_initial_frame): Initialize faces in all cases, not
19700 only when CANNOT_DUMP is defined.
19701 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
19703 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19705 * dispnew.c (add_window_display_history): Use const for the string
19706 pointer. Remove declaration, not needed.
19708 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19710 Use 'inline', not 'INLINE'.
19711 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
19712 * alloc.c, fontset.c (INLINE): Remove.
19713 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
19714 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
19715 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
19716 * gmalloc.c (register_heapinfo): Use inline unconditionally.
19717 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
19719 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19721 Make it possible to run ./temacs.
19723 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19724 syms_of_callproc does the same thing. Remove test for
19725 "initialized", do it in the caller.
19726 * emacs.c (main): Avoid calling set_initial_environment when dumping.
19728 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
19730 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
19731 (read_minibuf): Use get_minibuffer.
19732 (syms_of_minibuf): Use DEFSYM.
19733 (Qmetadata): New var.
19734 * data.c (Qbuffer): Don't make it static.
19735 (syms_of_data): Use DEFSYM.
19737 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19739 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
19740 (CCL_CODE_MIN): New macro.
19742 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
19744 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
19746 * eval.c (Qdebug): Now static.
19747 * lisp.h (Qdebug): Remove decl. This reverts a part of the
19748 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
19749 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
19751 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19753 * image.c: Various fixes to ImageMagick code comments.
19754 (Fimagemagick_types): Doc fix.
19756 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
19758 Minor fixes prompted by GCC 4.6.0 warnings.
19760 * xselect.c (converted_selections, conversion_fail_tag): Now static.
19762 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
19763 (x_clipboard_manager_save_all): Move extern decl to ...
19764 * xterm.h: ... here, so that it can be checked for consistency.
19766 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19768 * xselect.c (x_clipboard_manager_save_frame)
19769 (x_clipboard_manager_save_all): New functions.
19770 (Fx_clipboard_manager_save): Lisp function deleted.
19772 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
19773 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
19775 * xterm.h: Update prototype.
19777 2011-05-28 William Xu <william.xwl@gmail.com>
19779 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
19780 exiting (Bug#8239).
19782 2011-05-28 Jim Meyering <meyering@redhat.com>
19784 Avoid a sign-extension bug in crypto_hash_function.
19785 * fns.c (to_uchar): Define.
19786 (crypto_hash_function): Use it to convert some newly-signed
19787 variables to unsigned, to avoid sign-extension bugs. For example,
19788 without this change, (md5 "truc") would evaluate to
19789 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19790 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19791 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19793 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19795 Integer overflow fixes.
19797 * dbusbind.c: Serial number integer overflow fixes.
19798 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19799 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19800 to hold a serial number that is too large for a fixnum.
19801 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19802 Check for serial numbers out of range. Decode any serial number
19803 that was so large that it became a float. (Bug#8722)
19805 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19806 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19807 Use XFASTINT rather than XUINT when numbers are nonnegative.
19808 (xd_append_arg, Fdbus_method_return_internal):
19809 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19810 arguments, check that Lisp number is nonnegative, rather than
19811 silently wrapping negative numbers around. (Bug#8722)
19812 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19815 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19817 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19819 ccl: Add integer overflow checks.
19820 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19821 (IN_INT_RANGE): New macros.
19822 (ccl_driver): Use them to check for integer overflow when
19823 decoding a CCL program. Many of the new checks are whether XINT (x)
19824 fits in int; it doesn't always, on 64-bit hosts. The new version
19825 doesn't catch all possible integer overflows, but it's an
19826 improvement. (Bug#8719)
19828 * alloc.c (make_event_array): Use XINT, not XUINT.
19829 There's no need for unsigned here.
19831 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19832 This follows up to the 2011-05-06 change that substituted uintptr_t
19833 for EMACS_INT. This case wasn't caught back then.
19835 Rework Fformat to avoid integer overflow issues.
19836 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19837 now (part of C89). Include <verify.h>.
19838 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19839 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19840 (Fformat): Avoid the prepass trying to compute sizes; it was only
19841 approximate and thus did not catch overflow reliably. Instead, walk
19842 through the format just once, formatting and computing sizes as we go,
19843 checking for integer overflow at every step, and allocating a larger
19844 buffer as needed. Keep track separately whether the format is
19845 multibyte. Keep only the most-recently calculated precision, rather
19846 than them all. Record whether each argument has been converted to
19847 string. Use EMACS_INT, not int, for byte and char and arg counts.
19848 Support field widths and precisions larger than INT_MAX. Avoid
19849 sprintf's undefined behavior with conversion specifications such as %#d
19850 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19851 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19852 formatting out-of-range floating point numbers with int
19853 formats. (Bug#8668)
19855 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19857 * data.c: Avoid integer truncation in expressions involving floats.
19858 * data.c: Include <intprops.h>.
19859 (arith_driver): When there's an integer overflow in an expression
19860 involving floating point, convert the integers to floating point
19861 so that the resulting value does not suffer from catastrophic
19862 integer truncation. For example, on a 64-bit host (* 4
19863 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19864 Do not rely on undefined behavior after integer overflow.
19866 merge count_size_as_multibyte, parse_str_to_multibyte
19867 * character.c, character.h (count_size_as_multibyte):
19868 Rename from parse_str_to_multibyte; all uses changed.
19869 Check for integer overflow.
19870 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19871 since it's now a duplicate of the other. This is more of
19872 a character than a buffer op, so better that it's in character.c.
19873 * fns.c, print.c: Adjust to above changes.
19875 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19877 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19879 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19881 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19882 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19883 (x_clipboard_manager_save): Now static.
19884 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19886 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19887 (crypto_hash_function): Now static.
19888 Fix pointer signedness problems. Avoid unnecessary initializations.
19890 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19892 * termhooks.h (Vselection_alist): Make it terminal-local.
19894 * terminal.c (create_terminal): Initialize it.
19896 * xselect.c: Support for clipboard managers.
19897 (Vselection_alist): Move to termhooks.h as terminal-local var.
19898 (LOCAL_SELECTION): New macro.
19899 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19900 (symbol_to_x_atom): Remove gratuitous arg.
19901 (x_handle_selection_request, lisp_data_to_selection_data)
19902 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19903 (x_own_selection, x_get_local_selection, x_convert_selection):
19904 New arg, specifying work frame. Use terminal-local Vselection_alist.
19905 (some_frame_on_display): Delete unused function.
19906 (Fx_own_selection_internal, Fx_get_selection_internal)
19907 (Fx_disown_selection_internal, Fx_selection_owner_p)
19908 (Fx_selection_exists_p): New optional frame arg.
19909 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19910 (x_handle_selection_clear): Don't treat other terminals with the
19911 same keyboard specially. Use the terminal-local Vselection_alist.
19912 (x_clear_frame_selections): Use Frun_hook_with_args.
19914 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19916 * xterm.h: Add support for those atoms.
19918 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19920 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19921 (converted_selections, conversion_fail_tag): New global variables.
19922 (x_selection_request_lisp_error): Free the above.
19923 (x_get_local_selection): Remove unnecessary code.
19924 (x_reply_selection_request): Args changed; handle arbitrary array
19925 of converted selections stored in converted_selections.
19926 Separate the XChangeProperty and SelectionNotify steps.
19927 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19928 (x_convert_selection): New function.
19929 (x_handle_selection_event): Simplify.
19930 (x_get_foreign_selection): Don't ignore incoming requests while
19931 waiting for an answer; this will fail when we implement
19932 SAVE_TARGETS, and seems unnecessary anyway.
19933 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19934 (Vx_sent_selection_functions): Doc fix.
19936 2011-05-26 Leo Liu <sdl.web@gmail.com>
19938 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19940 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19942 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19944 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19945 for fringe update if it has periodic bitmap.
19946 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19947 and fringe_bitmap_periodic_p.
19949 * fringe.c (get_fringe_bitmap_data): New function.
19950 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19951 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19952 row. Mark glyph row for fringe update if periodicity changed.
19954 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19955 for fringe update unless it has periodic bitmap.
19957 2011-05-25 Kenichi Handa <handa@m17n.org>
19959 * xdisp.c (get_next_display_element): Set correct it->face_id for
19960 a static composition.
19962 2011-05-24 Leo Liu <sdl.web@gmail.com>
19965 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
19967 * fns.c (crypto_hash_function, Fsha1): New function.
19968 (Fmd5): Use crypto_hash_function.
19969 (syms_of_fns): Add Ssha1.
19971 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19973 * gnutls.c: Remove unused macros.
19974 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19975 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19976 Remove macros that are defined and never used.
19977 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19979 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19981 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19982 (Fx_get_selection_internal): Minor cleanup.
19983 (Fx_own_selection_internal): Rename arguments for consistency with
19986 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19988 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19990 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19992 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19994 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19996 * dispnew.c (scrolling_window): Don't exclude the case that the
19997 last enabled row in the desired matrix touches the bottom boundary.
19999 2011-05-21 Glenn Morris <rgm@gnu.org>
20001 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
20002 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
20003 and add some more files.
20005 2011-05-20 Eli Zaretskii <eliz@gnu.org>
20007 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
20008 report_file_error introduced by the change from 2011-05-07.
20010 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
20012 * systime.h (Time): Define only if emacs is defined.
20013 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
20014 where the include path doesn't have X11/X.h by default. See
20015 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
20017 2011-05-20 Kenichi Handa <handa@m17n.org>
20019 * composite.c (find_automatic_composition): Fix previous change.
20021 2011-05-20 Glenn Morris <rgm@gnu.org>
20023 * lisp.mk: New file, split from Makefile.in.
20024 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
20025 (shortlisp): Remove.
20026 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
20028 2011-05-19 Glenn Morris <rgm@gnu.org>
20030 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
20031 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
20032 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
20033 (lisp): Set the order to that of loadup.el.
20034 (shortlisp): Make it a copy of $lisp.
20035 (SOME_MACHINE_LISP): Remove.
20036 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
20037 Use just $shortlisp, not $SOME_MACHINE_LISP too.
20039 2011-05-18 Kenichi Handa <handa@m17n.org>
20041 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
20042 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
20043 (find_automatic_composition): Mostly rewrite for efficiency.
20045 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
20047 * makefile.w32-in: Update dependencies.
20049 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
20051 * menu.c: Include limits.h (fixes the MS-Windows build broken by
20052 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
20054 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
20056 Fix some integer overflow issues, such as string length overflow.
20058 * insdel.c (count_size_as_multibyte): Check for string overflow.
20060 * character.c (lisp_string_width): Check for string overflow.
20061 Use EMACS_INT, not int, for string indexes and lengths; in
20062 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
20063 the resulting string length overflows an EMACS_INT; instead,
20064 report a string overflow if no precision given. When checking for
20065 precision exhaustion, use a check that cannot possibly have
20066 integer overflow. (Bug#8675)
20067 * character.h (lisp_string_width): Adjust to new signature.
20069 * alloc.c (string_overflow): New function.
20070 (Fmake_string): Use it. This doesn't change behavior, but saves
20071 a few bytes and will simplify future changes.
20072 * character.c (string_escape_byte8): Likewise.
20073 * lisp.h (string_overflow): New decl.
20075 Fixups, following up to the user-interface timestamp change.
20076 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
20077 for UI timestamps, instead of unsigned long.
20078 * msdos.c (mouse_get_pos): Likewise.
20079 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
20080 * w32gui.h (Time): Define by including "systime.h" rather than by
20081 declaring it ourselves. (Bug#8664)
20083 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
20084 * image.c (clear_image_cache): Likewise.
20086 * term.c (term_mouse_position): Don't assume time_t wraparound.
20088 Be more systematic about user-interface timestamps.
20089 Before, the code sometimes used 'Time', sometimes 'unsigned long',
20090 and sometimes 'EMACS_UINT', to represent these timestamps.
20091 This change causes it to use 'Time' uniformly, as that's what X uses.
20092 This makes the code easier to follow, and makes it easier to catch
20093 integer overflow bugs such as Bug#8664.
20094 * frame.c (Fmouse_position, Fmouse_pixel_position):
20095 Use Time, not unsigned long, for user-interface timestamps.
20096 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
20097 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
20098 * keyboard.h (last_event_timestamp): Likewise.
20099 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
20100 * menu.h (xmenu_show): Likewise.
20101 * term.c (term_mouse_position): Likewise.
20102 * termhooks.h (struct input_event.timestamp): Likewise.
20103 (struct terminal.mouse_position_hook): Likewise.
20104 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
20105 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
20106 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
20107 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
20108 what it was before.
20109 * menu.h, termhooks.h: Include "systime.h", for Time.
20111 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
20112 Don't assume that the difference between two unsigned long values
20113 can fit into an integer. At this point, we know button_down_time
20114 <= event->timestamp, so the difference must be nonnegative, so
20115 there's no need to cast the result if double-click-time is
20116 nonnegative, as it should be; check that it's nonnegative, just in
20117 case. This bug is triggered when events are more than 2**31 ms
20118 apart (about 25 days). (Bug#8664)
20120 * xselect.c (last_event_timestamp): Remove duplicate decl.
20121 (x_own_selection): Remove needless cast to unsigned long.
20123 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
20124 that always fit in int. Use a sentinel instead of a counter, to
20125 avoid a temp and to allay GCC's concerns about possible int overflow.
20126 * frame.h (struct frame): Use int for menu_bar_items_used
20127 instead of EMACS_INT, since it always fits in int.
20129 * menu.c (grow_menu_items): Check for int overflow.
20131 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
20133 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
20134 Before, the code was not consistent. These values cannot exceed
20135 2**31 - 1 so there's no need to make them unsigned.
20136 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
20137 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
20138 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
20140 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
20142 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
20143 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
20144 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
20145 presumably because the widths might not match.
20147 * window.c (size_window): Avoid needless test at loop start.
20149 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
20151 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
20153 2011-05-12 Drew Adams <drew.adams@oracle.com>
20155 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
20157 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20159 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
20160 `width' to `bar_area_x' and `bar_area_width', respectively.
20161 (x_scroll_run): Take account of fringe background extension.
20163 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
20164 Rename local vars `left' and `width' to `bar_area_x' and
20165 `bar_area_width', respectively.
20166 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
20167 background extension.
20169 2011-05-10 Jim Meyering <meyering@redhat.com>
20171 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
20173 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
20175 * image.c (Finit_image_library): Return t for built-in image types,
20176 like pbm and xbm. (Bug#8640)
20178 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
20180 * w32menu.c (set_frame_menubar): Fix submenu allocation.
20182 2011-05-07 Eli Zaretskii <eliz@gnu.org>
20184 * w32console.c (Fset_screen_color): Doc fix.
20185 (Fget_screen_color): New function.
20186 (syms_of_ntterm): Defsubr it.
20188 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
20189 unlink the temporary file if Fcall_process didn't create it in the
20191 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
20192 child process will be redirected to a file specified with `:file'.
20193 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
20194 cue to call_process_cleanup not to close that handle.
20196 2011-05-07 Ben Key <bkey76@gmail.com>
20198 * makefile.w32-in: The bootstrap-temacs rule now makes use of
20199 one of two shell specific rules, either bootstrap-temacs-CMD or
20200 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
20201 to the previous implementation of the bootstrap-temacs rule.
20202 The bootstrap-temacs-CMD rule is similar to the previous
20203 implementation of the bootstrap-temacs rule except that it
20204 makes use of the ESC_CFLAGS variable instead of the CFLAGS
20207 These changes, along with some changes to nt/configure.bat,
20208 nt/gmake.defs, and nt/nmake.defs, are required to extend my
20209 earlier fix to add support for --cflags and --ldflags options
20210 that include quotes so that it works whether make uses cmd or
20213 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
20215 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
20216 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
20218 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
20219 a string. Handle both cases.
20220 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
20221 (Fdbus_register_method): Use Qinvalid_function.
20223 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20225 * makefile.w32-in: Update dependencies.
20226 (LISP_H): Add inttypes.h and stdin.h.
20227 (PROCESS_H): Add unistd.h.
20229 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20231 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20232 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20234 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20236 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20238 * term.c (vfatal): Remove stray call to va_end.
20239 It's not needed and the C Standard doesn't allow it here anyway.
20241 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20242 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20244 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20247 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20249 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20251 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20253 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20255 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20257 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20258 * charset.c (Fdefine_charset_internal): Don't initialize
20259 charset.code_space[15]. The value was garbage, on hosts with
20260 32-bit int (Bug#8600).
20262 * lread.c (read_integer): Be more consistent with string-to-number.
20263 Use string_to_number to do the actual conversion; this avoids
20264 rounding errors and fixes some other screwups. Without this fix,
20265 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20266 (digit_to_number): Move earlier, for benefit of read_integer.
20267 Return -1 if the digit is out of range for the base, -2 if it is
20268 not a digit in any supported base. (Bug#8602)
20270 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20272 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20273 to match comment at start of function. This also removes a
20274 GCC warning about overflow in a 32+64-bit port.
20276 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20278 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20279 Reported by Stefan Monnier in
20280 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20281 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20282 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20284 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20285 (EMACS_UINTPTR): Likewise, with uintptr_t.
20287 * lisp.h: Prefer 64-bit EMACS_INT if available.
20288 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20289 on 32-bit hosts that have 64-bit int, so that they can access
20291 However, temporarily disable this change unless the temporary
20292 symbol WIDE_EMACS_INT is defined.
20294 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20296 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20297 This removes an assumption that EMACS_INT and long are the same
20298 width as pointers. The assumption is true for Emacs porting targets
20299 now, but we want to make other targets possible.
20300 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20301 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20302 In the rest of the code, change types of integers that hold casted
20303 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20304 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20305 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20306 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20307 No need to cast type when ORing.
20308 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20309 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20310 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20311 assume EMACS_INT is the same width as char *.
20312 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20313 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20314 Remove no-longer-needed casts.
20315 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20316 (xg_tool_bar_help_callback, xg_make_tool_item):
20317 Use EMACS_INTPTR to hold an integer
20318 that will be cast to void *; this can avoid a GCC warning
20319 if EMACS_INT is not the same width as void *.
20320 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20321 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20322 (current_message_1, set_message_1):
20323 Use a local to convert to proper width without a cast.
20324 * xmenu.c (dialog_selection_callback): Likewise.
20326 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20327 Also, don't assume VALBITS / RAND_BITS is less than 5,
20328 and don't rely on undefined behavior when shifting a 1 left into
20330 * lisp.h (get_random): Change signature to match.
20332 * lread.c (hash_string): Use size_t, not int, for hash computation.
20333 Normally we prefer signed values; but hashing is special, because
20334 it's better to use unsigned division on hash table sizes so that
20335 the remainder is nonnegative. Also, size_t is the natural width
20336 for hashing into memory. The previous code used 'int', which doesn't
20337 retain enough info to hash well into very large tables.
20338 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20340 * dbusbind.c: Don't possibly lose pointer info when converting.
20341 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20342 Use XPNTR rather than XHASH, so that the high-order bits of
20343 the pointer aren't lost when converting through void *.
20345 * eval.c (Fautoload): Don't double-shift a pointer.
20347 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
20349 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20351 * gnutls.c (DEF_GNUTLS_FN):
20352 * image.c (DEF_IMGLIB_FN): Make function pointers static.
20354 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
20356 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
20359 2011-05-05 Eli Zaretskii <eliz@gnu.org>
20361 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
20362 New version that can reserve upto 2GB of heap space.
20364 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
20366 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
20368 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
20370 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
20371 `gnutls_certificate_set_x509_key_file'.
20373 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
20375 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
20376 Update dependencies.
20378 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20380 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
20381 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
20382 Remove unused parameter `fildes'.
20383 * process.c (read_process_output, send_process): Don't pass it.
20385 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20387 Fix previous change: the library cache is defined in w32.c.
20388 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
20389 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
20391 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20393 Implement dynamic loading of GnuTLS on Windows.
20395 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.

20430 * process.c: Include lisp.h before w32.h, not after.
20431 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20432 instead of gnutls_record_check_pending.
20434 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
20436 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20438 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

20484 rather than `XVECTOR (FOO)->size'.
20486 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20487 inttypes.h, as a gnulib replacement is used if it not available in
20490 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20492 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.

20509 %llo or %llx format is passed. (Bug#8545)
20511 * window.c (window_scroll_line_based): Use a marker instead of
20512 simple variables to record original value of point. (Bug#7952)
20514 * doprnt.c (doprnt): Fix the case where a multibyte sequence
20515 produced by %s or %c overflows available buffer space. (Bug#8545)
20517 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20519 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
20520 (SIZE_MAX): Move defn after all includes, as they might #define it.
20522 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20524 * w32.c (init_environment): Warn about defaulting HOME to C:\.
20526 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20528 * keyboard.c (Qdelayed_warnings_hook): Define.
20529 (command_loop_1): Run `delayed-warnings-hook'
20530 if Vdelayed_warnings_list is non-nil.
20531 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
20532 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
20534 2011-04-28 Eli Zaretskii <eliz@gnu.org>
20536 * doprnt.c (doprnt): Don't return value smaller than the buffer
20537 size if the message was truncated. (Bug#8545).
20539 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20541 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

20548 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20550 * makefile.w32-in: Update dependencies.
20552 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20554 Improve `doprnt' and its usage. (Bug#8545)
20555 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20556 `format_end'. Remove support for %l as a conversion specifier.
20557 Don't use xrealloc. Improve diagnostics when the %l size modifier
20558 is used. Update the commentary.
20560 * eval.c (verror): Simplify calculation of size_t.
20562 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20565 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20567 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20570 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20572 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20573 This makes this file independent of the recent pseudovector change.
20575 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20577 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20579 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20580 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20581 Remove unused local.
20582 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20584 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20585 GCC 4.6.0 optimizes based on type-based alias analysis.
20586 For example, if b is of type struct buffer * and v of type struct
20587 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20588 != &v->size, and therefore "v->size = 1; b->size = 2; return
20589 v->size;" must therefore return 1. This assumption is incorrect
20590 for Emacs, since it type-puns struct Lisp_Vector * with many other
20591 types. To fix this problem, this patch adds a new type struct
20592 vectorlike_header that documents the constraints on layout of vectors
20593 and pseudovectors, and helps optimizing compilers not get fooled
20594 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20595 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20596 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20598 (XSETPVECTYPE): Rewrite in terms of new macro.
20599 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20600 This is a bit clearer, and further avoids the possibility of
20601 undesirable aliasing.
20602 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20603 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20604 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20605 since Lisp_Subr is a special case (no "next" field).
20606 (ASIZE): Now uses header.size rather than size.
20607 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20608 to avoid the hassle of writing XVECTOR (foo)->header.size.
20609 (struct vectorlike_header): New type.
20610 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20611 object, to help avoid aliasing.
20612 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20613 (SUBRP): Likewise, since Lisp_Subr is a special case.
20614 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20615 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20616 (struct Lisp_Hash_Table): Combine first two members into a single
20617 struct vectorlike_header member. All uses of "size" and "next" members
20618 changed to be "header.size" and "header.next".
20619 * buffer.h (struct buffer): Likewise.
20620 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20621 * frame.h (struct frame): Likewise.
20622 * process.h (struct Lisp_Process): Likewise.
20623 * termhooks.h (struct terminal): Likewise.
20624 * window.c (struct save_window_data, struct saved_window): Likewise.
20625 * window.h (struct window): Likewise.
20626 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20627 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20628 * buffer.c (init_buffer_once): Likewise.
20629 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20631 * process.c (Fformat_network_address): Use local var for size,
20634 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20636 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20637 * data.c (atof): Remove decl; no longer used or needed.
20638 (digit_to_number): Move to lread.c.
20639 (Fstring_to_number): Use new string_to_number function, to be
20640 consistent with how the Lisp reader treats infinities and NaNs.
20641 Do not assume that floating-point numbers represent EMACS_INT
20642 without losing information; this is not true on most 64-bit hosts.
20643 Avoid double-rounding errors, by insisting on integers when
20644 parsing non-base-10 numbers, as the documentation specifies.
20645 * lisp.h (string_to_number): New decl, replacing ...
20646 (isfloat_string): Remove.
20647 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20648 (read1): Do not accept +. and -. as integers; this
20649 appears to have been a coding error. Similarly, do not accept
20650 strings like +-1e0 as floating point numbers. Do not report
20651 overflow for integer overflows unless the base is not 10 which
20652 means we have no simple and reliable way to continue.
20653 Break out the floating-point parsing into a new
20654 function string_to_number, so that Fstring_to_number parses
20655 floating point numbers consistently with the Lisp reader.
20656 (digit_to_number): Move here from data.c. Make it static inline.
20657 (E_CHAR, EXP_INT): Remove, replacing with ...
20658 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20659 (string_to_number): New function, replacing isfloat_string.
20660 This function checks for valid syntax and produces the resulting
20661 Lisp float number too. Rework it so that string-to-number
20662 no longer mishandles examples like "1.0e+". Use strtoumax,
20663 so that overflow for non-base-10 numbers is reported only when
20664 there's no portable and simple way to convert to floating point.
20666 * textprop.c (set_text_properties_1): Rewrite for clarity,
20667 and to avoid GCC warning about integer overflow.
20669 * intervals.h (struct interval): Use EMACS_INT for members
20670 where EMACS_UINT might cause problems. See
20671 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20672 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20673 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20675 (offset_intervals): Tell GCC not to worry about length overflow
20676 when negating a negative length.
20678 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20679 (overrun_check_free): Likewise.
20681 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20682 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20685 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20686 (gnutls_make_error): Rename local to avoid shadowing.
20687 (gnutls_emacs_global_deinit): ifdef out; not used.
20688 (Fgnutls_boot): Use const for pointer to readonly storage.
20689 Comment out unused local. Fix pointer signedness problems.
20691 * lread.c (openp): Don't stuff size_t into an 'int'.
20692 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20693 about possible signed overflow.
20695 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20696 (GDK_KEY_g): Don't define if already defined.
20697 (xg_prepare_tooltip): Avoid pointer signedness problem.
20698 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20700 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20701 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20703 * xfns.c (Fx_window_property): Simplify a bit,
20704 to make a bit faster and to avoid GCC 4.6.0 warning.
20705 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20707 * fns.c (internal_equal): Don't assume size_t fits in int.
20709 * alloc.c (compact_small_strings): Tighten assertion a little.
20711 Replace pEd with more-general pI, and fix some printf arg casts.
20712 * lisp.h (pI): New macro, generalizing old pEd macro to other
20713 conversion specifiers. For example, use "...%"pI"d..." rather
20714 than "...%"pEd"...".
20715 (pEd): Remove. All uses replaced with similar uses of pI.
20716 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20717 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20718 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20719 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20720 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20721 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20722 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20724 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20725 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20726 * print.c (safe_debug_print, print_object): Likewise.
20727 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20729 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20730 avoiding the 0 flag, which is not portable.
20731 * process.c (Fmake_network_process): Use pI to avoid cast.
20732 * region-cache.c (pp_cache): Likewise.
20733 * xdisp.c (decode_mode_spec): Likewise.
20734 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
20735 behavior on 64-bit hosts with printf arg.
20736 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
20737 (x_stop_queuing_selection_requests): Likewise.
20738 (x_get_window_property): Don't truncate byte count to an 'int'
20741 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20742 here, since it parses constructs like leading '-' and spaces,
20743 which are not wanted; and it overflows with large numbers.
20744 Instead, simply match F[0-9]+, which is what is wanted anyway.
20746 * alloc.c: Remove unportable assumptions about struct layout.
20747 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20748 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20749 (allocate_vectorlike, make_pure_vector): Use the new macros,
20750 plus offsetof, to remove unportable assumptions about struct layout.
20751 These assumptions hold on all porting targets that I know of, but
20752 they are not guaranteed, they're easy to remove, and removing them
20753 makes further changes easier.
20755 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20756 This doesn't fix a bug but makes the code clearer.
20757 (string_overrun_cookie): Now const. Use initializers that
20758 don't formally overflow signed char, to avoid warnings.
20759 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20760 can cause Emacs to crash when string overrun checking is enabled.
20761 (allocate_buffer): Don't assume sizeof (struct buffer) is a
20762 multiple of sizeof (EMACS_INT); it need not be, if
20763 alignof(EMACS_INT) < sizeof (EMACS_INT).
20764 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
20766 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
20768 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
20770 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
20772 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
20773 supposed to be handshaking. (Bug#8556)
20774 Reported by Paul Eggert <eggert@cs.ucla.edu>.
20776 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
20778 * lisp.h (Qdebug): List symbol.
20779 * eval.c (Qdebug): Restore global linkage.
20780 * keyboard.c (debug-on-event): New variable.
20781 (handle_user_signal): Break into debugger when debug-on-event
20782 matches the current signal symbol.
20784 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
20786 * alloc.c (check_sblock, check_string_bytes)
20787 (check_string_free_list): Convert to standard C.
20789 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
20791 * w32.c (emacs_gnutls_push): Fix typo.
20793 2011-04-25 Eli Zaretskii <eliz@gnu.org>
20795 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
20796 "cast to pointer from integer of different size".
20798 Improve doprnt and its use in verror. (Bug#8545)
20799 * doprnt.c (doprnt): Document the set of format control sequences
20800 supported by the function. Use SAFE_ALLOCA instead of always
20803 * eval.c (verror): Don't limit the buffer size at size_max-1, that
20804 is one byte too soon. Don't use xrealloc; instead xfree and
20807 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
20809 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
20812 * gnutls.c: Renamed global_initialized to
20813 gnutls_global_initialized. Added internals for the
20814 :verify-hostname-error, :verify-error, and :verify-flags
20815 parameters of `gnutls-boot' and documented those parameters in the
20816 docstring. Start callback support.

21299 * xdisp.c (redisplay_window): Simplify code, to make it more
21300 obvious that ignore_mouse_drag_p is not accessed if !defined
21301 USE_GTK && !defined HAVE_NS.
21303 * intervals.c: Make symbols static if they're not exported.

21306 * intervals.h (merge_interval_right, delete_interval): Remove decls.
21308 * insdel.c: Make symbols static if they're not exported.
21309 However, leave prepare_to_modify_buffer alone. It's never
21310 called from outside this function, but that appears to be a bug.

21312 (adjust_after_replace, signal_before_change): Now static.
21313 (adjust_after_replace_noundo): Remove; unused.

21341 * font.c (font_close_object): Now static.
21342 * font.h (font_close_object): Remove.
21343 * fontset.c (FONTSET_OBJLIST): Remove.
21344 (free_realized_fontset) #if-0 the body, which does nothing.
21345 (face_suitable_for_char_p): #if-0, as it's never called.
21346 * fontset.h (face_suitable_for_char_p): Remove decl.
21347 * xfaces.c (face_at_string_position):
21348 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
21349 since 0 is always ASCII.
21351 * fns.c (weak_hash_tables): Now static.
21353 * fileio.c: Make symbols static if they're not exported.

21372 * editfns.c, lisp.h (get_operating_system_release): Remove.
21373 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
21374 worth the hassle of breaking this out.
21376 * xterm.c: Make symbols static if they're not exported.
21377 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

21480 * buffer.c (buffer_count): Remove unused var.

21489 * atimer.h (run_all_atimers): Remove; not exported.
21491 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
21492 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
21493 was inaccessible from Lisp.
21494 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
21495 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
21497 alloc.c: Import and export fewer symbols, and remove unused items.
21498 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
21500 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
21501 it's not optimized away by whole-program optimization.
21502 (message_enable_multibyte, free_misc): Remove.
21503 (catchlist, handlerlist, mark_backtrace):
21504 Declare only if BYTE_MARK_STACK.

21513 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
21514 (mark_backtrace): Define only if BYTE_MARK_STACK.
21515 * xdisp.c (message_enable_multibyte): Now static.
21517 Declare Lisp_Object Q* variables to be 'static' if not exported.
21518 This makes it easier for human readers (and static analyzers)
21519 to see whether these variables are used from other modules.
21520 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
21521 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
21522 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

21531 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
21533 * lisp.h (DEFINE_FUNC): Make sname 'static'.
21535 Make Emacs functions such as Fatom 'static' by default.
21536 This makes it easier for human readers (and static analyzers)
21537 to see whether these functions can be called from other modules.
21538 DEFUN now defines a static function. To make the function external
21539 so that it can be used in other C modules, use the new macro DEFUE.
21540 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
21541 (Finit_image_library):
21542 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
21543 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
21544 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
21545 Remove decls, since these functions are now static.
21546 (Funintern, Fget_internal_run_time): New decls, since these functions
21547 were already external.
21549 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
21550 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

21556 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
21557 Mark functions with DEFUE instead of DEFUN,
21558 if they are used in other modules.
21559 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
21560 decls for now-static functions.
21561 * buffer.h (Fdelete_overlay): Remove decl.
21562 * callproc.c (Fgetenv_internal): Mark as internal.
21563 * composite.c (Fremove_list_of_text_properties): Remove decl.

21570 * fileio.c (Fmake_symbolic_link): New forward static decl.
21571 * image.c (Finit_image_library): New forward static decl.
21572 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
21573 * intervals.h (Fprevious_property_change):
21574 (Fremove_list_of_text_properties): Remove decls.
21575 * keyboard.c (Fthis_command_keys): Remove decl.
21576 (Fcommand_execute): New forward static decl.

21592 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
21594 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
21597 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21599 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21600 when at ZV. (Bug#8487)
21602 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
21604 * charset.c (Fclear_charset_maps): Use xfree instead of free.
21606 * keyboard.c (parse_tool_bar_item): Likewise.
21607 * sound.c (sound_cleanup, alsa_close): Likewise.
21608 * termcap.c (tgetent): Likewise.
21609 * xfns.c (x_default_font_parameter): Likewise.
21610 * xsettings.c (read_and_apply_settings): Likewise.
21612 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21613 (overrun_check_free): Protoize.
21615 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21617 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21618 since callers should never pass a negative size.
21619 Change the signature to match that of plain 'read' and 'write'; see
21620 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21621 * lisp.h: Update prototypes of emacs_write and emacs_read.
21623 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21625 * xdisp.c (redisplay_window): Don't try to determine the character
21626 position of the scroll margin if the window start point w->startp
21627 is outside the buffer's accessible region. (Bug#8468)
21629 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21631 Fix write-region and its subroutines for buffers > 2GB.
21632 * fileio.c (a_write, e_write): Modify declaration of arguments and
21633 local variables to support buffers larger than 2GB.
21634 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21636 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21637 argument, local variables, and return value.
21639 * lisp.h: Update prototypes of emacs_write and emacs_read.
21641 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21643 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21645 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21647 Fix more problems found by GCC 4.6.0's static checks.
21649 * xdisp.c (vmessage): Use a better test for character truncation.
21651 * charset.c (load_charset_map): <, not <=, for optimization,
21652 and to avoid potential problems with integer overflow.
21653 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21654 * casetab.c (set_identity, shuffle): Likewise.
21655 * editfns.c (Fformat): Likewise.
21656 * syntax.c (skip_chars): Likewise.
21658 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21659 This also lets GCC 4.6.0 generate slightly better loop code.
21661 * callint.c (Fcall_interactively): <, not <=, for optimization.
21662 (Fcall_interactively): Count the number of arguments produced,
21663 not the number of arguments given. This is simpler and lets GCC
21664 4.6.0 generate slightly better code.
21666 * ftfont.c: Distingish more carefully between FcChar8 and char.
21667 The previous code passed unsigned char * to a functions like
21668 strlen and xstrcasecmp that expect char *, which does not
21669 conform to the C standard.
21670 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21671 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21672 char * when the C standard requires it.
21674 * keyboard.c (read_char): Remove unused var.
21676 * eval.c: Port to Windows vsnprintf (Bug#8435).
21677 Include <limits.h>.
21678 (SIZE_MAX): Define if the headers do not.
21679 (verror): Do not give up if vsnprintf returns a negative count.
21680 Instead, grow the buffer. This ports to Windows vsnprintf, which
21681 does not conform to C99. Problem reported by Eli Zaretskii.
21682 Also, simplify the allocation scheme, by avoiding the need for
21683 calling realloc, and removing the ALLOCATED variable.
21685 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21687 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21688 But keep the doprint source code for now, as we might revamp it
21689 and use it again (Bug#8435).
21690 * lisp.h (doprnt): Remove.
21691 * Makefile.in (base_obj): Remove doprnt.o.
21692 * deps.mk (doprnt.o): Remove.
21694 error: Print 32- and 64-bit integers portably (Bug#8435).
21695 Without this change, on typical 64-bit hosts error ("...%d...", N)
21696 was used to print both 32- and 64-bit integers N, which relied on
21697 undefined behavior.
21698 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21699 * lisp.h (error, verror): Mark as printf-like functions.
21700 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.

21850 This avoids several warnings with gcc -Wstrict-overflow.
21851 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21852 directly, rather than having caller test rule sign. This avoids
21853 some unnecessary tests.
21854 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21855 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21856 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.

21859 (xfont_open): Avoid unnecessary tests.
21861 * composite.c (composition_gstring_put_cache): Use unsigned integer.

21873 since the condition is always true at first.
21875 * intervals.c (graft_intervals_into_buffer): Mark var as used.

21906 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21908 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21909 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21910 can always succeed if overflow has undefined behavior.
21912 * search.c (boyer_moore, wordify): Remove vars set but not used.
21913 (wordify): Omit three unnecessary tests.
21915 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

21943 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21944 that are set but not used.
21946 * xfns.c (make_invisible_cursor): Don't return garbage
21947 if XCreateBitmapFromData fails (Bug#8410).
21949 * xselect.c (x_get_local_selection, x_handle_property_notify):
21950 Remove vars that are set but not used.
21952 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
21953 (make_invisible_cursor): Initialize a possibly-uninitialized variable.

21974 that is set but not used.
21976 * print.c (print_object): Remove var that is set but not used.
21978 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21979 The gnulib version avoids calling malloc in the usual case,
21980 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21981 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21982 * filelock.c (current_lock_owner): Likewise.
21983 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21984 * sysdep.c: Include allocator.h, careadlinkat.h.
21985 (emacs_no_realloc_allocator): New static constant.
21986 (emacs_readlink): New function.
21987 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21988 ../lib/careadlinkat.h.
21990 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21992 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21993 first non-nil return value).

22009 (get_per_char_metric): Remove parameter `f', unused since
22010 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

22055 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
22056 (FletX, Flet): Obey lexical binding.
22057 (Fcommandp): Handle closures.
22058 (Feval): New `lexical' arg.
22059 (eval_sub): New function extracted from Feval. Use it almost
22060 everywhere where Feval was used. Look up vars in lexical env.
22062 (Ffunctionp): Move from subr.el.
22063 (Ffuncall): Handle closures.
22064 (apply_lambda): Remove `eval_flags'.
22065 (funcall_lambda): Handle closures and new byte-code-functions.
22066 (Fspecial_variable_p): New function.
22067 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,

22070 * doc.c (Fdocumentation, store_function_docstring):
22071 * data.c (Finteractive_form): Handle closures.
22073 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
22076 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
22078 (exec_byte_code): New function extracted from Fbyte_code to handle new
22079 calling convention for byte-code-functions. Add new byte-codes.

22094 (redisplay_window): Even when falling back on "recentering",
22095 position point in the window according to scroll-conservatively,
22096 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
22098 (try_scrolling): When point is above the window, allow searching
22099 as far as scroll_max, or one screenful, to compute vertical
22100 distance from PT to the scroll margin position. This prevents
22101 try_scrolling from unnecessarily failing when
22102 scroll-conservatively is set to a value slightly larger than the
22103 window height. Clean up the case of PT below the margin at bottom
22104 of window: scroll_max can no longer be INT_MAX. When aggressive
22105 scrolling is in use, don't let point enter the opposite scroll
22106 margin as result of the scroll.
22107 (syms_of_xdisp) <scroll-conservatively>: Document the
22108 threshold of 100 lines for never-recentering scrolling.

22117 (redisplay_internal): Remove parameter `preserve_echo_area',
22118 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.

22164 (Fbacktrace_frame): Don't assume nframes fits in int.
22166 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
22168 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
22171 * term.c (produce_glyphless_glyph): Remove unnecessary test.
22173 * cm.c (calccost): Turn while-do into do-while, for clarity.
22175 * keyboard.c (syms_of_keyboard): Use the same style as later
22176 in this function when indexing through an array. This also
22177 works around GCC bug 48267.
22179 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
22181 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

22184 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
22186 * keyboard.c, keyboard.h (num_input_events): Now size_t.
22187 This avoids undefined behavior on integer overflow, and is a bit
22188 more convenient anyway since it is compared to a size_t variable.
22190 Variadic C functions now count arguments with size_t, not int.
22191 This avoids an unnecessary limitation on 64-bit machines, which
22192 caused (substring ...) to crash on large vectors (Bug#8344).
22193 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
22194 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
22195 All variadic functions and their callers changed accordingly.
22196 (struct gcpro.nvars): Now size_t, not int. All uses changed.

22198 * editfns.c (general_insert_function): Likewise.
22199 * eval.c (struct backtrace.nargs, interactive_p)
22200 (internal_condition_case_n, run_hook_with_args, apply_lambda)
22201 (funcall_lambda, mark_backtrace): Likewise.
22202 * fns.c (concat): Likewise.
22203 * frame.c (x_set_frame_parameters): Likewise.
22204 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
22205 0 if not found, not -1. All callers changed.
22207 * alloc.c (garbage_collect): Don't assume stack size fits in int.
22208 (stack_copy_size): Now size_t, not int.
22209 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

22214 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
22215 All callers changed.
22217 * lisp.h (multibyte_char_to_unibyte):
22218 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
22219 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

22225 * xdisp.c (message_dolog, set_message_1): All callers changed.
22227 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
22229 * keyboard.c (safe_run_hook_funcall): New function.
22230 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
22231 don't set the hook to nil, but remove the offending function instead.
22232 (Qcommand_hook_internal): Remove, unused.
22233 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
22234 Vcommand_hook_internal.
22236 * eval.c (enum run_hooks_condition): Remove.
22237 (funcall_nil, funcall_not): New functions.
22238 (run_hook_with_args): Call each function through a `funcall' argument.
22239 Remove `cond' argument, now redundant.

22246 * dispextern.h (string_buffer_position): Remove declaration.
22248 * print.c (strout): Remove parameter `multibyte', unused since
22249 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
22251 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
22252 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
22253 All callers changed.
22255 * w32.c (_wsa_errlist): Use braces for struct initializers.
22257 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
22258 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
22259 All callers changed.

22261 used outside xdisp.c).
22262 (cursor_row_p): Remove parameter `w', unused since
22263 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

22265 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
22266 All callers changed.
22268 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
22270 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

22281 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
22283 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

22296 2011-03-26 Eli Zaretskii <eliz@gnu.org>
22298 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
22299 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
22301 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
22303 * w32.c (read_unc_volume): Use parameter `henum', instead of
22304 global variable `wget_enum_handle'.
22306 * keymap.c (describe_vector): Remove parameters `indices' and
22307 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

22322 * gtkutil.c (xg_maybe_add_timer):
22323 * keyboard.c (readable_events):
22324 * process.c (wait_reading_process_output):
22325 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
22327 * insdel.c (adjust_markers_gap_motion):
22328 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

22402 2011-03-23 Julien Danjou <julien@danjou.info>
22404 * term.c (Fsuspend_tty, Fresume_tty):
22405 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
22406 * window.c (temp_output_buffer_show):

22413 * callint.c (Fcall_interactively):
22414 * buffer.c (Fkill_all_local_variables):
22415 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22417 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22418 unconditionally since it does the check itself.
22420 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22422 Fix more problems found by GCC 4.5.2's static checks.
22424 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22425 the first time through the loop, since we know p0 < p1 then.
22426 This also avoids a gcc -Wstrict-overflow warning.
22428 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22429 leading to a memory leak, possible in functions like
22430 load_charset_map_from_file that can allocate an unbounded number
22431 of objects (Bug#8318).
22433 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22434 that could (at least in theory) be that large.
22436 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22437 This is less likely to overflow, and avoids undefined behavior if
22438 overflow does occur. All callers changed. Use strtoul to scan
22439 for the unsigned long integer.
22440 (pint2hrstr): Simplify and tune code slightly.
22441 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
22443 * scroll.c (do_scrolling): Work around GCC bug 48228.
22444 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

22449 This also avoids a warning with gcc -Wstrict-overflow.
22451 * fileio.c (Fcopy_file): Report error if fchown or fchmod
22454 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
22456 * process.c (Fmake_network_process): Use socklen_t, not int,
22457 where POSIX says socklen_t is required in portable programs.
22458 This fixes a porting bug on hosts like 64-bit HP-UX, where
22459 socklen_t is wider than int (Bug#8277).
22460 (Fmake_network_process, server_accept_connection):
22461 (wait_reading_process_output, read_process_output):
22464 * process.c: Rename or move locals to avoid shadowing.

22471 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
22472 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
22474 Make tparam.h and terminfo.c consistent.
22475 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22476 Include tparam.h instead, since it declares them.
22477 * cm.h (PC): Remove extern decl; tparam.h now does this.
22478 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22479 * terminfo.c: Include tparam.h, to check interfaces.
22480 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22481 (tparam): Adjust signature to match interface in tparam.h;
22482 this removes some undefined behavior. Check that outstring and len
22483 are zero, which they always are with Emacs.
22484 * tparam.h (PC, BC, UP): New extern decls.
22486 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22487 (xftfont_open): Rename locals to avoid shadowing.
22489 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
22490 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
22491 (OTF_TAG_SYM): Omit macro if not needed.
22492 (ftfont_list): Remove unused local.
22493 (get_adstyle_property, ftfont_pattern_entity):
22494 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
22495 Rename locals to avoid shadowing.
22497 * xfont.c (xfont_list_family): Mark var as initialized.
22499 * xml.c (make_dom): Now static.
22501 * composite.c (composition_compute_stop_pos): Rename local to
22503 (composition_reseat_it): Remove unused locals.
22504 (find_automatic_composition, composition_adjust_point): Likewise.
22505 (composition_update_it): Mark var as initialized.
22506 (find_automatic_composition): Mark vars as initialized,
22507 with a FIXME (Bug#8290).
22509 character.h: Rename locals to avoid shadowing.
22510 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
22511 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
22512 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
22513 (BUF_DEC_POS): Be more systematic about renaming local temporaries
22514 to avoid shadowing.
22516 * textprop.c (property_change_between_p): Remove; unused.
22518 * intervals.c (interval_start_pos): Now static.
22520 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
22522 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
22523 Rename locals to avoid shadowing.
22525 * sound.c (wav_play, au_play, Fplay_sound_internal):
22526 Fix pointer signedness.
22527 (alsa_choose_format): Remove unused local var.
22528 (wav_play): Initialize a variable to 0, to prevent undefined
22529 behavior (Bug#8278).
22531 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22533 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22535 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22536 clobbering (Bug#8298).
22537 * sysdep.c (sys_subshell): Likewise.
22538 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22540 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22541 This should get cleaned up, so that child_setup has the
22542 same signature on all platforms.
22544 * callproc.c (call_process_cleanup): Now static.
22545 (relocate_fd): Rename locals to avoid shadowing.
22547 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
22549 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
22550 not to be necessary, and produces flickering.
22552 2011-03-20 Glenn Morris <rgm@gnu.org>
22554 * config.in: Remove file.
22556 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
22558 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
22559 are now in src/globals.h.
22560 (syms_of_minibuf): Remove spurious & from previous change.

22570 * xfaces.c (Fx_load_color_file):
22571 Read color file from absolute filename (bug#8250).

22577 2011-03-17 Eli Zaretskii <eliz@gnu.org>
22579 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

22586 (sigchld_handler): Now static.
22588 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
22589 That way, the code declares only the vars that it needs.
22590 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
22591 * s/cygwin.h (PTY_ITERATION): Likewise.
22592 * s/darwin.h (PTY_ITERATION): Likewise.

22595 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
22596 * process.c (allocate_pty): Don't declare stb unless it's needed.
22598 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
22599 (CONSTANTLIM): Remove; unused.
22600 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
22601 Define only if needed.
22603 * unexelf.c (unexec): Name an expression,

22675 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
22676 some of which prompt warnings from gcc -Wbad-function-cast.
22677 (Fformat_time_string, Fencode_time, Finsert_char):
22678 (Ftranslate_region_internal, Fformat):

22706 (Fmemory_limit): Cast sbrk's returned value to char *.
22708 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

22711 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
22713 Use functions, not macros, for up- and down-casing (Bug#8254).
22714 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22715 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
22716 to use the following functions instead of these macros.
22717 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
22718 EMACS_INT, since callers assume the returned value fits in int.
22719 (upcase1): Likewise, for UPCASE_TABLE.
22720 (uppercasep, lowercasep, upcase): New static inline functions.
22721 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

22731 (regex_compile, re_match_2_internal): Mark locals as initialized.
22732 (RETALLOC_IF): Define only if needed.
22733 (WORDCHAR_P): Likewise. This one is never needed, but is used
22734 only in a comment talking about a compiler bug, so put inside
22735 the #if 0 of that comment.
22736 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22737 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

22763 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
22764 New macros, so that the caller can use some names other than
22765 gcpro1, gcpro2, etc.
22766 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22768 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22769 argument, for consistency with GCPRO2_VAR, etc: it is now the
22770 prefix of the variable, not the variable itself. All uses
22772 * dired.c (directory_files_internal, file_name_completion):
22773 Rename locals to avoid shadowing.
22775 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22776 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22777 dired.c's scmp function, had undefined behavior.
22778 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22779 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22780 * buffer.h: ... to here, because these macros use current_buffer,
22781 and the new implementation with inline functions needs to have
22782 current_buffer in scope now, rather than later when the macros
22784 (downcase, upcase1): New static inline functions.
22785 (DOWNCASE, UPCASE1): Reimplement using these functions.
22786 This avoids undefined behavior in expressions like
22787 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22788 from race conditions in accessing the global variables
22789 case_temp1 and case_temp2.
22790 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22791 * lisp.h (case_temp1, case_temp2): Remove their decls.
22792 * character.h (ASCII_CHAR_P): Move from here ...
22793 * lisp.h: ... to here, so that the inline functions mentioned
22794 above can use them.
22796 * dired.c (directory_files_internal_unwind): Now static.
22798 * fileio.c (file_name_as_directory, directory_file_name):

22801 (file_name_as_directory): Use const pointers when appropriate.
22802 (Fexpand_file_name): Likewise. In particular, newdir might
22803 point at constant storage, so make it a const pointer.
22804 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
22805 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22807 (Fset_file_times, Finsert_file_contents, auto_save_error):

22812 to avoid shadowing.
22814 * marker.c (bytepos_to_charpos): Remove; unused.
22816 * lisp.h (verify_bytepos, count_markers): New decls,
22817 so that gcc does not warn that these functions aren't declared.
22819 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22820 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22821 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22822 (copy_text): Remove unused local var.
22824 * filelock.c (within_one_second): Now static.
22825 (lock_file_1): Rename local to avoid shadowing.
22827 * buffer.c (fix_overlays_before): Mark locals as initialized.
22828 (fix_start_end_in_overlays): Likewise. This function should be
22829 simplified by using pointers-to-pointers, but that's a different
22831 (switch_to_buffer_1): Now static.
22832 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22833 (report_overlay_modification): Rename locals to avoid shadowing.

22836 Fix pointer signedness issue.
22837 (sys_subshell): Mark local as volatile if checking for lint,
22838 to suppress a gcc -Wclobbered warning that does not seem to be right.
22839 (MAXPATHLEN): Define only if needed.
22841 * process.c (serial_open, serial_configure): Move decls from here ...
22842 * systty.h: ... to here, so that they can be checked.
22844 * fns.c (get_random, seed_random): Move extern decls from here ...
22845 * lisp.h: ... to here, so that they can be checked.
22847 * sysdep.c (reset_io): Now static.
22848 (wait_for_termination_signal): Remove; unused.
22850 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
22851 (copy_keymap_item, append_key, push_text_char_description):
22853 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
22854 (DENSE_TABLE_SIZE): Remove; unused.
22855 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
22856 (describe_map_tree):
22857 Rename locals to avoid shadowing.
22859 * keyboard.c: Declare functions static if they are not used elsewhere.

23006 For example, without this patch (encode-time 0 0 0 1 1
23007 1152921504606846976) returns the obviously-bogus value (-948597
23008 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
23009 reports time overflow. See
23010 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
23011 * deps.mk (editfns.o): Depend on ../lib/intprops.h.

23026 * editfns.c (time_overflow): New function, refactoring common code.
23027 (Fformat_time_string, Fdecode_time, Fencode_time):
