3 Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
4 This bug was introduced by my 2013-02-25 change that simplified
5 data_start configuration. Without this change, on GNU/Linux
6 an Emacs configured with --enable-profiling fails immediately
7 due to a profiler signal.
8 * Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
9 with these flags. On platforms where special flags are needed
10 when linking temacs, the flags are now in LD_SWITCH_SYSTEM_TEMACS.
11 (ALL_CFLAGS): Remove $(PROFILING_CFLAGS).
12 (.c.o, .m.o): Compile with $(PROFILING_CFLAGS).

87 This makes it easier to visualize quantities on a number line.
88 This patch doesn't apply to all such range checks,
89 only to the range checks affected by the 2013-03-24 change.
90 This patch reverts most of the 2013-03-24 change.

219 Use contents slot, not buffer, where appropriate.
220 * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW
221 to avoid deleted windows. Use contents slot instead of buffer.
222 * buffer.c, dispextern.h, editfns.c, fileio.c, font.c, fringe.c:
223 * indent.c, insdel.c, keyboard.c, keymap.c, minibuf.c, msdos.c:

474 * dispnew.c, frame.c, w32fns.c, window.c, xdisp.c, xfns.c:
475 Adjust users where appropriate.
477 2013-03-20 Dmitry Antipov <dmantipov@yandex.ru>

563 source bytes directly.
564 (produce_chars): Call insert_from_gap with the new arg 0.
565 (encode_coding): Likewise.

599 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
600 too so that these builds can use Cygwin's file conversion
601 functions. (We've been building and linking cygw32.o all along
602 and just not using it.)
604 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
606 File synchronization fixes (Bug#13944).
607 * Makefile.in (LIB_FDATASYNC): New macro.

618 activated, call w32fullscreen_hook, to make sure the new frame
619 dimensions are in effect. (Bug#13937)
621 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
623 * xdisp.c (init_iterator): Simplify because both character and byte
624 positions are either specified or -1. Add eassert. Adjust comment.
625 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
626 character and byte positions can be obtained from marker.

643 a function pointer type; the C Standard requires this.
645 * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
646 Include <sys/param.h> unconditionally, as that works elsewhere and
647 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
648 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
651 2013-03-11 Paul Eggert <eggert@cs.ucla.edu>

729 (adjust_after_insert): Call adjust_after_replace with the new arg
732 2013-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
734 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
735 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
736 from Elisp via unread-command-events.
738 * keyboard.c (access_keymap_keyremap): Accept nil return value from
739 functions to mean "no change".
741 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
743 region-cache.c, scroll.c, search.c: Use bool for booleans.
744 * lisp.h (compile_pattern):
745 * scroll.c (do_scrolling, do_direct_scrolling):
746 * search.c (struct regexp_cache, compile_pattern_1)
747 (compile_pattern, string_match_1, search_command)
748 (trivial_regexp_p, search_buffer, Freplace_match, match_limit)
749 (search_regs_saved, Fregexp_quote):
750 Use bool for boolean.
751 * region-cache.c (region_cache_forward, region_cache_backward):
752 Fix comments to match code: these functions return int, not boolean.
754 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
756 * search.c (find_newline): Accept start and end byte positions
757 as arguments and allow -1 if not known.

763 Adjust call to find_newline.
764 * indent.c (vmotion): Adjust calls to find_newline_no_quit.

767 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
768 (get_visually_first_element, move_it_vertically_backward): Likewise.
769 Obtain byte position from the display iterator, where appropriate.
771 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>

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

796 when you need just to move to the previous buffer position.
797 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
799 2013-03-07 Eli Zaretskii <eliz@gnu.org>
801 * .gdbinit (prowlims): Display the enabled_p flag of the row.

872 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
874 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
875 * sysdep.c (list_system_processes)
876 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
877 Make it a stub in this case; otherwise the build might fail,
878 and this code hasn't been tested on such hosts anyway.
879 Problem reported by Nelson H. F. Beebe in
880 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
881 and analyzed by Jérémie Courrèges-Anglas in
882 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
884 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
886 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
887 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
888 (get_visually_first_element, move_it_vertically_backward): Ajust users.
889 * bidi.c (bidi_find_paragraph_start): Likewise.
890 * indent.c (vmotion): Likewise.
892 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
894 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
895 * filelock.c: Include <c-ctype.h>.
896 (MAX_LFINFO): New top-level constant.
897 (lock_info_type): Remove members pid, boot_time. Add members at,
898 dot, colon. Change user member to be the entire buffer, not a
899 pointer. This allows us to handle the case where a foreign
900 pid or boot time exceeds the local range. All uses changed.
901 (LINKS_MIGHT_NOT_WORK): New constant.
902 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
903 (defined_WINDOWSNT): Remove.
904 (MAKE_LOCK_NAME, file_in_lock_file_name):
905 Always use .#FILE (not .#-FILE) for the file lock,
906 even if it is a regular file.
907 (rename_lock_file): New function.
908 (create_lock_file): Use it.
909 (create_lock_file, read_lock_data):
910 Prefer a symbolic link for the lock file, falling back on a
911 regular file if symlinks don't work. Do not try to create
912 symlinks on MS-Windows, due to security hassles. Stick with
913 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
914 link, rename, unlink, mkstemp) when creating locks, as a GNUish
915 host may be using a Windowsish file system, and cannot use
916 MS-Windows-only system calls. Fall back on mktemp if mkstemp
917 doesn't work. Don't fail merely because of a symlink-contents
918 length limit in the current file system; fall back on regular
919 files. Increase the symlink contents length limit to 8 KiB, this
920 should be big enough for any real use and doesn't crunch the
922 (create_lock_file, lock_file_1, read_lock_data):
923 Simplify allocation of lock file buffers now that they fit in 8 KiB.
924 (lock_file_1): Return error number, not bool. All callers changed.
925 (ELOOP): New macro, if not already defined.
926 (read_lock_data): Return size of lock file contents, not Lisp object.
927 All callers changed. Handle a race condition if some other process
928 replaces a regular-file lock with a symlink lock or vice versa,
929 while we're trying to read the lock.
930 (current_lock_owner): Parse contents more carefully, to help avoid
931 confusing a regular-file lock with some other application's use
932 of the file. Check for lock file contents being too long, or
933 not parsing correctly.
934 (current_lock_owner, lock_file):
935 Allow foreign pid and boot times that exceed the local range.
936 (current_lock_owner, lock_if_free, lock_file):
937 Simplify allocation of lock file contents.
938 * w32.c (sys_rename_replace): New function, containing most of
939 the contents of the old sys_rename.
940 (sys_rename): Use it.
941 (fchmod): New dummy function.
942 * w32.h (sys_rename_replace, fchmod): New decls.
944 2013-03-05 Eli Zaretskii <eliz@gnu.org>
946 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
947 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
948 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
949 <dmantipov@yandex.ru>.
951 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
953 * composite.c (get_composition_id, fill_gstring_header):
954 Use make_uninit_vector where appropriate.
955 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
956 * xselect.c (clean_local_selection_data): Likewise.
958 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
960 Fix misuse of ImageMagick that caused core dump (Bug#13846).
961 * image.c (imagemagick_load_image): Calculate height and width
962 after flattening the image, not before.
964 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
966 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
967 * ftfont.c (ftfont_shape_by_flt): Likewise.
968 * w32uniscribe.c (uniscribe_shape): Likewise.
970 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
972 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
973 The old approach, which fell back on DIR/.#FILE.0 through
974 DIR/.#FILE.9, had race conditions that could not be easily fixed.
975 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
976 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
977 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
978 because the locking mechanism was never reliable in that case).
979 This patch fixes this and other bugs discovered by a code
980 inspection that was prompted by
981 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
982 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
983 to avoid interoperability problems between the MS-Windows and
984 non-MS-Windows implementations. MS-Windows and non-MS-Windows
985 instances of Emacs now ignore each others' locks.
986 * filelock.c (defined_WINDOWSNT): New constant.
987 (MAKE_LOCK_NAME, fill_in_lock_file_name):
988 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
989 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
990 regular files on MS-Windows hosts.
991 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
992 Use SAFE_ALLOCA to avoid problems with long file names.
993 (MAX_LFINFO): Now a local constant, not a global macro.
994 (IS_LOCK_FILE): Remove.
995 (lock_file_1): Don't inspect errno if symlink call succeeds;
997 (lock_file): Document that this function can return if lock
999 (lock_file): Don't access freed storage.
1001 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>
1003 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
1005 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1007 * textprop.c: Use bool for booleans.
1008 (validate_interval_range, Fadd_text_properties)
1009 (Fremove_text_properties): Prefer bool to int when either works.
1011 2013-03-02 Eli Zaretskii <eliz@gnu.org>
1013 * textprop.c (Fadd_text_properties, Fremove_text_properties):
1014 If the interval tree changes as a side effect of calling
1015 modify_region, re-do processing starting from the call to
1016 validate_interval_range. (Bug#13743)
1018 2013-02-28 Eli Zaretskii <eliz@gnu.org>
1020 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
1023 2013-02-27 Eli Zaretskii <eliz@gnu.org>
1025 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
1026 _SH_DENYRW flag, instead of emacs_open, to deny any other process
1027 access to the lock file until it is written and closed.

1040 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
1042 Minor textprop integer cleanup.
1043 * intervals.h, textprop.c (add_text_properties_from_list):
1044 Return void, not int, since nobody uses the return value.
1045 * textprop.c (validate_plist, add_properties, remove_properties)
1046 (Fadd_text_properties):
1047 Don't assume list length fits in int.
1048 (interval_has_all_properties, interval_has_some_properties)
1049 (interval_has_some_properties_list, add_properties, remove_properties)
1050 (Fadd_text_properties, Fremove_text_properties)

1054 (Fremove_list_of_text_properties):
1055 Reindent do-while as per GNU style.

1059 Implement CLASH_DETECTION for MS-Windows.
1061 * filelock.c [WINDOWSNT]: Include w32.h.
1062 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
1063 function of that name. Up-case the macro arguments.
1064 (IS_LOCK_FILE): New macro.
1065 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
1066 (create_lock_file): New function, with body extracted from
1068 [WINDOWSNT]: Implement lock files by writing a regular file with
1069 the lock information as its contents.
1070 (read_lock_data): New function, on Posix platforms just calls
1072 [WINDOWSNT]: Read the lock info from the file.
1073 (current_lock_owner): Call read_lock_data instead of calling
1074 emacs_readlinkat directly.
1075 (lock_file) [WINDOWSNT]: Run the file name through
1078 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
1079 just check if the process by that PID exists.
1081 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
1082 also present, as doing so will fail to error out if the file
1085 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
1087 * textprop.c (Fadd_text_properties, Fremove_text_properties)
1088 (Fremove_list_of_text_properties): Skip all of the intervals in
1089 the region between START and END that already have resp. don't
1090 have the requested properties, not just the first one.
1091 Add assertions that the loop afterwards always modifies the
1092 properties. (Bug#13743)
1094 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>

1104 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
1105 (START_FILES): Remove. All uses removed.
1106 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
1107 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
1108 (buildobj.h): Use it.
1109 ($(ALLOBJS)): Depend on globals.h.
1110 (temacs$(EXEEXT)): Use $(ALLOBJS).
1111 * autodeps.mk (ALLOBJS): Move to Makefile.in.
1112 * deps.mk (vm-limit.o):
1113 * makefile.w32-in ($(BLD)/vm-limit.$(O)):
1114 Do not depend on mem-limits.h.
1115 * emacs.c (__do_global_ctors, __do_global_ctors_aux)
1116 (__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__)

1122 * vm-limit.c: Move most of mem-limits.h's contents here.
1123 (data_start): New decl. It's OK if this is approximate,
1124 so simplify-away some unnecessary exactness.
1125 (POINTER): Remove; all uses removed.
1126 (data_space_start): Now char *, to avoid casts.
1127 (exceeds_lisp_ptr): New function, replacing the old
1128 EXCEEDS_LISP_PTR macro. All uses changed.
1129 (check_memory_limits): Simplify and remove casts.
1130 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.

1149 Assume C89 or better.
1150 * ralloc.c (SIZE, POINTER, NIL):

1152 Remove, replacing all uses with C89 equivalents. These old
1153 symbols were present only for porting to pre-C89 platforms.
1155 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
1157 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.

1173 2013-02-19 Daniel Colascione <dancol@dancol.org>
1175 * sheap.c (report_sheap_usage): Use message, not message1, so
1176 that we don't try to create a buffer while we're in the middle
1177 of dumping Emacs. Explain why.
1179 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
1181 * search.c (find_newline): Return byte position in bytepos.

1194 2013-02-19 Eli Zaretskii <eliz@gnu.org>
1196 * w32proc.c (new_child): Avoid leaking handles if the subprocess
1197 resources were not orderly released.
1199 2013-02-17 Eli Zaretskii <eliz@gnu.org>
1201 * xdisp.c (x_draw_vertical_border): For a window that is neither

1228 unconditionally. (Bug#9066)
1230 * w32.c (set_errno): Reset h_errno and don't set it to any other
1231 value. Set errno instead.

1246 * keyboard.c (read_char): Fix calculation of auto-save time out
1247 when auto-save-timeout is less than 4. (Bug#13720)

1256 make sure errno is set to an appropriate value. (Bug#13546)
1257 (socket_to_fd): Add assertion against indexing fd_info[] with a
1258 value that is out of bounds.
1259 (sys_accept): If fd is negative, do not set up the child_process
1260 structure for reading.
1262 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
1264 * composite.c (fill_gstring_header): Remove useless prototype.

1276 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1278 Fix AIX port (Bug#13650).
1279 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
1280 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
1281 was #undeffed earlier, so it cannot be used as a macro here.
1282 Use the constant and not the macro.
1284 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1286 * w32proc.c (new_child): If no vacant slots are found in
1287 child_procs[], make another pass looking for slots whose process
1288 has exited or died. (Bug#13546)
1290 * w32.c (sys_pipe): When failing due to file descriptors above
1291 MAXDESC, set errno to EMFILE.
1292 (_sys_read_ahead): Update cp->status when failing to read serial
1293 communications input, so that the status doesn't stay at
1294 STATUS_READ_IN_PROGRESS. (Bug#13546)
1296 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>

1308 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
1310 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>

1316 Break long line. Remove useless prototype and format comment.
1318 2013-02-13 Glenn Morris <rgm@gnu.org>
1320 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
1322 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1324 Improve AIX port some more (Bug#13650).
1325 With this, it should be as good as it was in 23.3, though it's
1326 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
1327 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
1328 * unexaix.c (start_of_text): Remove.
1329 (_data, _text): Declare as char[], not int, as AIX manual suggests.
1330 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
1331 (orig_load_scnptr, orig_data_scnptr):
1332 Now off_t, not long, since they are file offsets.
1333 (make_hdr): Use _data, not start_of_data ().
1334 This is the key part of the fix.
1335 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
1336 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
1338 * pre-crt0.c (data_start): Initialize to 1.
1339 This ports to compilers that optimize the external declaration
1340 'int x = 0;' as if it were 'int x;' to shrink the executable.
1342 Improve AIX port (Bug#13650).
1343 This doesn't fix the bug, but it makes progress: Emacs builds now.
1344 * unexaix.c: Include inttypes.h, stdarg.h.
1345 (report_error, report_error_1): Mark as _Noreturn.
1346 (report_error): Don't report the wrong errno.
1347 (report_error_1): Now varargs. All callers changed.
1348 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
1349 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
1350 (write_ptr): Use %p to print address rather than %lx and a cast
1351 to unsigned long. Grow buffer a bit, to be safer.
1353 2013-02-13 Eli Zaretskii <eliz@gnu.org>
1355 * bidi.c (bidi_resolve_neutral): After finding the next
1356 non-neutral character, accept NEUTRAL_ON type as well, because
1357 directional control characters, such as LRE and RLE, have their
1358 type converted to that by bidi_resolve_weak. This avoids aborts
1359 when LRE/RLE follows a run of neutrals.
1360 (bidi_move_to_visually_next): Assert that return value of
1361 bidi_peek_at_next_level is non-negative. Negative values will
1364 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1366 Minor getenv-related fixes.
1367 * callproc.c (Fcall_process_region) [!DOS_NT]:
1368 Avoid unnecessary duplicate call to getenv.
1369 * callproc.c (init_callproc):
1370 * dispnew.c (init_display):
1371 * sysdep.c (sys_subshell):
1372 Omit unnecessary cast of getenv or egetenv.
1374 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
1376 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
1377 Update dependencies.
1379 2013-02-12 Eli Zaretskii <eliz@gnu.org>
1381 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
1383 (display_line): Set w->region_showing to the value of
1384 it->region_beg_charpos, not to -1. This fixes redisplay
1385 optimization when cursor is moved up after M->. (Bug#13623)
1387 (try_scrolling): Scroll text up more if point is too close to ZV
1388 and inside the scroll margin. This makes sure point is moved
1389 outside the scroll margin in these cases.
1391 * window.h (struct window): region_showing can no longer be
1394 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
1396 Tune by using memchr and memrchr.
1397 * doc.c (Fsnarf_documentation):
1398 * fileio.c (Fsubstitute_in_file_name):
1399 * search.c (find_newline, scan_newline):
1400 * xdisp.c (pos_visible_p, display_count_lines):
1401 Use memchr and memrchr rather than scanning byte-by-byte.
1402 * search.c (find_newline): Rename from scan_buffer.

1416 (active_maps): New function.
1417 (test_undefined): Also return true for nil bindings.
1418 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
1419 a single (composed) keymap. Remember `first_event' to choose the right
1420 set of active keymaps. Recompute the set of keymaps after receiving
1421 the first event. Remove GOBBLE_FIRST_EVENT.
1422 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
1423 * keyboard.h (read_char): Update declaration.
1424 * lread.c (read_filtered_event): Adjust call to read_char.
1426 2013-02-11 Eli Zaretskii <eliz@gnu.org>
1428 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1429 Don't use the limitation on backwards movement when lines are truncated

1432 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
1434 * marker.c (set_marker_internal): If desired position is passed

1443 2013-02-10 Eli Zaretskii <eliz@gnu.org>
1445 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1446 When text lines are longer than window's screen lines, don't move back
1447 too far. This speeds up some redisplay operations. (Bug#13675)
1449 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
1451 * syntax.c (scan_sexps_forward): Fix byte position calculation

1463 (sxhash_float): Return EMACS_UINT, for consistency with the other
1465 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
1466 non-static inline function and therefore can't use static vars.
1467 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
1468 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
1469 with the other hash functions.
1471 2013-02-09 Eli Zaretskii <eliz@gnu.org>
1473 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
1474 XXXXXX part of the temporary file pattern is not downcased even
1475 when w32-downcase-file-names is non-nil. (Bug#13661)
1477 * xdisp.c (decode_mode_spec): Remove handling of %t.
1479 * msdos.c (careadlinkatcwd): Remove.
1481 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
1483 * lread.c (skip_dyn_bytes): New function (bug#12598).

1534 (ns_last_use_native_fullscreen): New variable.
1535 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.

1537 if isFullscreen returns YES.
1538 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
1539 (check_native_fs): New function.

1556 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
1557 (syms_of_nsterm): Add ns-use-native-fullscreen.
1559 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
1561 * fileio.c (Qchoose_write_coding_system): Now static.
1563 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1565 * xdisp.c (window_buffer_changed): region_showing can be negative,
1566 which still means region is being displayed.
1567 (redisplay_internal): Resurrect code that forced redisplay of the
1568 whole window when showing region and the mark has changed.
1569 Record the new mark position to allow redisplay optimizations.
1570 (display_line): If it->region_beg_charpos is non-zero, set the
1571 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1573 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1574 not bitfield of 1 bit.
1576 2013-02-03 Daniel Colascione <dancol@dancol.org>
1578 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1579 daemon mode works on cygw32 when Emacs is installed and not just
1582 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1584 Avoid file time stamp bug on MS-Windows (Bug#13149).
1585 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1586 as FAT32 doesn't update time stamps when truncating them.
1587 Also, check that a file time stamp is not a multiple of 100 ns;
1588 this should catch all instances of the problem on MS-Windows,
1589 as its native file system resolution is 100 ns or worse, and
1590 checking for a non-multiple of 100 ns should impose only a small
1591 overhead on systems with ns resolution.
1593 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1595 Avoid encoding file names on MS-Windows when they need to be run
1596 through dostounix_filename.
1597 * w32.c (normalize_filename): Accept an additional argument
1598 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1599 downcase it even if w32-downcase-file-names is non-nil.
1600 (dostounix_filename): Accept an additional argument MULTIBYTE and
1601 pass it to normalize_filename.
1602 (emacs_root_dir): Adjust.
1604 * msdos.h (dostounix_filename): Adjust prototype.
1606 * w32.h (dostounix_filename): Adjust prototype.
1608 * msdos.c (dostounix_filename): Accept an additional argument and
1610 (init_environment): Adjust callers of dostounix_filename.
1612 * fileio.c (Ffile_name_directory, file_name_as_directory)
1613 (directory_file_name, Fexpand_file_name)
1614 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1616 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1618 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1619 variables, as egetenv is case-insensitive for DOS_NT.
1621 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1622 with an encoded file name.
1624 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1625 Adjust calls to dostounix_filename.
1627 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1629 * unexw32.c (unexec): Adjust call to dostounix_filename.
1631 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1633 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1636 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1639 * callproc.c (Fcall_process): Make sure program name in PATH and
1640 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1641 is passed to exec/spawnve, which fails unless the file-name
1644 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1645 even if w32-quote-process-args is nil.
1647 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1649 Fix timestamp bug when write-region appends nothing (Bug#13149).
1650 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1651 the file's time stamp doesn't change if Emacs happens to write nothing
1652 to the file, and on a buggy file system this could cause Emacs to
1653 incorrectly infer that the file system doesn't have the bug.
1654 Avoid this problem by inhibiting the inference in this case.
1656 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1658 * window.h (struct window): Convert base_line_number, base_line_pos
1659 and column_number_displayed members from Lisp_Object to ptrdiff_t.

1669 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1670 (try_scrolling, try_cursor_movement, redisplay_window)
1671 (try_window_reusing_current_matrix, try_window_id, display_line)
1672 (display_mode_lines, decode_mode_spec): Adjust users.
1673 * .gdbinit (pwinx): Do not print sequence_number.
1675 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1677 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1678 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1679 * dired.c: Include <fcntl.h>.
1680 (open_directory): New function, which uses open and fdopendir
1681 rather than opendir. DOS_NT platforms still use opendir, though.

1684 (directory_files_internal, Ffile_attributes): Use it.
1685 (file_attributes, file_name_completion_stat): First arg is now fd,
1686 not dir name. All uses changed. Use fstatat rather than lstat +
1688 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1689 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1690 (emacs_readlinkat): New function, with much of the old
1691 Ffile_symlink_p, but with an fd argument for speed.
1692 It uses readlinkat rather than careadlinkatcwd, so that it
1693 need not assume the working directory.
1694 (Ffile_symlink_p): Use it.
1695 * filelock.c (current_lock_owner): Use emacs_readlinkat
1696 rather than emacs_readlink.
1697 * lisp.h (emacs_readlinkat): New decl.
1698 (READLINK_BUFSIZE, emacs_readlink): Remove.
1699 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1700 (emacs_norealloc_allocator, emacs_readlink): Remove.
1701 This stuff is moved to fileio.c.
1702 * w32.c (fstatat, readlinkat): New functions.
1703 (careadlinkat): Don't check that fd == AT_FDCWD.

1720 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1721 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1724 * w32.c (w32_get_long_filename, init_environment, readlink):
1725 Support file names encoded in DBCS codepages.
1726 (readlink): Use the current file-name-coding-system, not the ANSI
1727 codepage, to decode and handle targets of symlinks.
1729 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1731 * w32.c (opendir): Now accepts a 'const char *'.
1733 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>

1745 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1747 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>

1750 debugging code. Adjust comment style here and there.
1751 * insdel.c (insert_1): Remove.
1752 * lisp.h (insert_1): Remove prototype.
1753 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
1755 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1757 * w32.c (max_filename_mbslen): New function.
1758 (normalize_filename, readdir): Use it to detect locales where ANSI
1759 encoding of file names uses a double-byte character set (DBCS).
1760 If a DBCS encoding is used, advance by characters using
1761 CharNextExA, instead of incrementing a 'char *' pointer.
1762 Use _mbslwr instead of _strlwr. (Bug#13515)
1764 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial

1801 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1803 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1805 * xdisp.c (message2, message2_nolog): Remove functions.
1806 (message3, message3_nolog): Extract nbytes and multibyteness directly
1807 from the string. Change all callers.
1808 (message3_nolog): Don't set message_enable_multibyte since set_message
1809 will reset it anyway.
1810 (message1, message1_nolog): Use message3.
1811 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1812 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1813 (set_message): Drop all but the second arg, which has to be a string.

1827 * editfns.c (message_text, message_length): Remove vars.
1828 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1829 * fileio.c (auto_save_error): Use message3 instead of message2.

1849 (Fwindow_line_height, set_window_buffer, Frecenter)
1850 (Fsplit_window_internal, Fdelete_other_windows_internal)
1851 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
1852 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
1853 * xdisp.c (check_window_end, reconsider_clip_changes)
1854 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1855 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1856 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1858 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1860 * xdisp.c (mark_window_display_accurate): Simplify the loop
1861 assuming that the only one of vchild, hchild or buffer window
1862 slots is non-nil. Call mark_window_display_accurate_1 for
1863 the leaf windows only.
1864 (mark_window_display_accurate_1): Always assume leaf window.
1867 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1869 * emacs.c (Qkill_emacs_hook): Now static.
1871 * fileio.c (Finsert_file_contents): Simplify.
1872 Remove unnecessary assignments and tests.
1874 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1876 * w32.c (acl_set_file): Don't test for errors unless
1877 set_file_security returns FALSE. Avoids spurious errors when
1880 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1882 * fileio.c (Finsert_file_contents): Revert code introduced at
1883 2013-01-18 in favor of the simpler and generally better fix.
1884 Save stack space by removing 'buffer' and reusing 'read_buf'
1887 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1889 * lisp.h (eabs): Define unconditionally (Bug#13419).
1890 The old "#if !defined (eabs)" was an unnecessary revenant of back
1891 when this macro was called "abs". Document 'eabs' better.
1893 2013-01-19 Glenn Morris <rgm@gnu.org>
1895 * fns.c (Frandom): Doc fix.
1897 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1899 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1900 segfault when there are lots of overlays.
1902 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1903 when there are lots of overlays.
1904 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1905 for the details and a way to reproduce.
1907 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1909 * fileio.c: Use O_APPEND to append.
1910 This corresponds better to the natural interpretation of "append",
1911 and avoids the need to open the output file twice, or to invoke
1912 lseek when APPEND is neither nil nor a number.
1913 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1914 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1915 file possibly twice, and lseeking to its end; this avoids the
1916 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1917 at the same time: the combination is never needed and apparently
1918 it doesn't work with DOS_NT.
1920 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1921 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1923 Allow floating-point file offsets.
1924 Problem reported by Vitalie Spinu in
1925 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1926 * fileio.c (emacs_lseek): Remove.
1927 (file_offset): New function.
1928 (Finsert_file_contents, Fwrite_region): Use it.
1930 2013-01-19 Chong Yidong <cyd@gnu.org>
1932 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1933 aborting on Fsignal (Bug#13289).
1935 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1937 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1938 set_file_security as failure due to insufficient privileges.
1939 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1940 (fstat): Return owner and group like 'stat' and 'lstat' do.
1942 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1944 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1945 The bug was observed on Ubuntu operating inside a virtual machine,
1946 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1947 The workaround introduces a race condition on non-buggy hosts,
1948 but it's an unlikely race and anyway there's a nearly identical
1949 nearby race that can't be fixed.
1950 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1952 (Fwrite_region): Test for file system time stamp bug.
1953 (init_fileio): New function.
1954 * lisp.h (init_fileio): Declare it.
1955 * emacs.c (main): Call it.
1957 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1958 and make it more consistent with other stat-failure diagnostics.
1960 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
1962 Fix crash when inserting data from non-regular files.
1963 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
1964 for the error description produced by valgrind.
1965 * fileio.c (read_non_regular): Rename to read_contents.
1966 Free Lisp_Save_Value object used to pass parameters.
1967 (read_non_regular_quit): Rename to read_contents_quit.
1968 (Finsert_file_contents): Redesign internal file reading loop to adjust
1969 gap and end positions after each read and so help make_gap to work
1970 properly. Do not signal an I/O error too early and so do not leave
1971 not yet decoded characters in a buffer, which was the reason of
1972 redisplay crash. Use list2 to build return value. Adjust comments.
1974 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1976 Close a race when statting and reading files (Bug#13149).
1977 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1978 This avoids a race if the file is renamed between stat and open.
1979 This race is not the problem originally noted in Bug#13149;
1980 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
1982 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
1984 * lisp.h (toplevel): Add comment about using Lisp_Save_Value
1985 objects, related functions and macros.

1989 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
1990 * alloc.c (format_save_value): Rename to make_save_value.
1991 (make_save_pointer): New function.
1992 (record_xmalloc): Use make_save_pointer.
1993 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
1994 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
1995 Change users of make_save_value to make_save_pointer.
1996 Likewise for format_save_value and make_save_value.

2007 * alloc.c (free_save_value): Now static.
2009 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2011 * keymap.c (map_keymap_internal): Use format_save_value.
2012 (map_keymap_char_table_item): Adjust accordingly.
2013 * fileio.c (non_regular_fd, non_regular_inserted)
2014 (non_regular_nbytes): Remove.
2015 (Finsert_file_contents): Convert trytry to ptrdiff_t.
2016 Use format_save_value to pass parameters to read_non_regular.
2017 (read_non_regular): Use XSAVE_ macros to extract parameters.
2019 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
2021 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
2023 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2025 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
2026 extraction from any Lisp_Save_Value slot. Add type checking.
2027 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
2028 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
2029 * xselect.c: All users changed.
2031 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

2041 * editfns.c (save_excursion_save): Use format_save_value.
2042 (save_excursion_restore): Use XSAVE_OBJECT.
2044 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
2046 Avoid needless casts with XSAVE_POINTER.
2047 * alloc.c (mark_object) [GC_MARK_STACK]:
2048 * dired.c (directory_files_internal_unwind):
2049 * fileio.c (do_auto_save_unwind):
2050 * gtkutil.c (pop_down_dialog):
2051 * keymap.c (map_keymap_char_table_item):
2052 * lread.c (load_unwind):
2053 * nsmenu.m (pop_down_menu):
2054 * print.c (print_object) [GC_MARK_STACK]:
2055 * xfns.c (clean_up_file_dialog):
2056 * xmenu.c (cleanup_widget_value_tree):
2057 Omit casts between XSAVE_POINTER and a pointer type.
2059 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
2061 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
2062 * eval.c (eval_sub): Protect `form' from being GCed before its
2063 car and cdr becomes protected with the backtrace entry.
2065 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
2067 Make Lisp_Save_Value more versatile storage for up to four objects.

2077 (free_save_value): Likewise.
2078 (mark_object): Likewise.
2079 * editfns.c (save_excursion_save): Pack everything within
2080 Lisp_Save_Value and so avoid xmalloc.
2081 (save_excursion_restore): Adjust to match new layout. Use free_misc
2082 because we do not allocate extra memory any more. Add eassert.
2083 * print.c (print_object): New code to print Lisp_Save_Value. Do not
2084 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
2085 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
2086 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:

2094 Bug#11484 with LCD smoothing on.
2096 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
2098 Fix SIGDANGER handlers, for AIX (Bug#13408).
2099 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
2100 Move handlers here from emacs.c; they were out of place.

2125 (nsfont_open): Move block_input earlier. Add unblock_input before early
2127 (nsfont_draw): Add block/unblock_input calls.
2129 2013-01-12 Dmitry Antipov <dmantipov@yandex.ru>
2131 * indent.c (Fvertical_motion): Remove now-incorrect GCPROs

2150 string cross-reference(s).
2152 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
2154 Avoid unnecessary byte position calculation for the gap movement.
2155 Since all users of move_gap do CHAR_TO_BYTE for other purposes
2156 anyway, all of them should use move_gap_both instead.
2157 * lisp.h (move_gap): Remove prototype.
2158 * insdel.c (move_gap): Remove.
2159 (move_gap_both): Add eassert.

2168 * term.c (init_tty): Use them instead of rolling our own code.
2169 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
2170 switches from 'signal' to 'pthread_sigmask', which is safer in
2171 multithreaded applications.
2172 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
2173 which has already arranged for that.
2174 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.

2184 Omit buffer_slot_type_mismatch and use generic predicates to enforce
2185 the type of per-buffer values where appropriate.
2186 * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to
2187 predicate, which is how it's really used now. Adjust comment.
2188 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
2189 * buffer.c (buffer_slot_type_mismatch): Remove.
2190 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to

2195 right-fringe-width, scroll-bar-width and buffer-display-count.
2196 Use Qstringp for default-directory, buffer-file-name,
2197 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
2198 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
2200 * data.c (store_symval_forwarding): Adjust to call the predicate.
2202 2013-01-09 Juanma Barranquero <lekktu@gmail.com>
2204 * w32.c (get_name_and_id, acl_set_file):
2205 * w32term.c (w32fullscreen_hook): Remove unused local variables.

2217 (make_gap_1): New function to adjust the gap of any buffer.
2218 * coding.c (coding_alloc_by_making_gap): Use it.
2219 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
2220 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.
2222 2013-01-08 Juri Linkov <juri@jurta.org>
2224 * xfaces.c (tty_supports_face_attributes_p): Return 0 for the case
2225 of (supports :underline (:style wave)). (Bug#13000)

2243 trailing dash is properly added.
2245 2013-01-05 Eli Zaretskii <eliz@gnu.org>
2247 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
2248 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
2249 digits for buffer positions, before misalignment starts.
2250 Display "0" for integer "object" field.
2251 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
2252 Display the newline glyph more unambiguously.

2305 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
2306 (update_frame_tool_bar): Check toolbar_is_packed for packing.
2307 Show all on TOOLBAR_TOP_WIDGET.
2308 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
2309 by TOOLBAR_TOP_WIDGET.
2310 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
2311 Check toolbar_is_packed.
2312 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
2313 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2314 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
2316 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2317 (xg_update_menubar): Update title only if
2318 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2319 (xg_update_submenu): Skip tearoff only if
2320 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2321 (xg_initialize): Initialize xg_detached_menus only if
2322 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2324 * xterm.h (struct x_output): Surround handlebox_widget with
2325 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
2326 toolbar_in_hbox is bool.
2328 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
2330 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
2331 (LIBS_GNUSTEP): Define.
2332 (LIBES): Add $(LIBS_GNUSTEP).
2333 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
2335 2012-12-30 Eli Zaretskii <eliz@gnu.org>
2337 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
2338 continuation glyph on a TTY with an indication of an empty line.
2341 2012-12-29 Eli Zaretskii <eliz@gnu.org>
2343 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
2344 file's SELinux context or ACLs successfully set, nil otherwise.
2346 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
2348 * w32proc.c (reader_thread): Avoid passing NULL handles to
2349 SetEvent and WaitForSingleObject.
2351 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
2353 Port EXTERNALLY_VISIBLE to Clang 3.2.
2354 * conf_post.h (__has_attribute): New macro.
2355 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
2357 2012-12-27 Glenn Morris <rgm@gnu.org>
2359 * cygw32.c (Fcygwin_convert_file_name_to_windows)
2360 (Fcygwin_convert_file_name_from_windows): Doc fixes.
2362 2012-12-27 Eli Zaretskii <eliz@gnu.org>
2364 * fileio.c (file_name_as_directory, directory_file_name):
2365 Accept an additional argument MULTIBYTE to indicate whether the input C
2366 came from a multibyte or a unibyte Lisp string; all callers
2367 adjusted. Don't assume the input string is always multibyte.
2369 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
2370 don't ENCODE_FILE them, and return a unibyte string if the input
2372 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
2373 don't assume the input strings will always be multibyte. If the
2374 input strings are multibyte, decode strings obtained from C
2377 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2379 * lisp.h (toplevel): Add two notices to the comment about
2380 defining a new Lisp data type.
2381 * print.c (print_object): If Lisp_Save_Value object's pointer
2382 is the address of a memory area containing Lisp_Objects, try
2384 * alloc.c (valid_lisp_object_p): Adjust comment.
2386 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2388 * keyboard.c (record_asynch_buffer_change): Initialize an event
2389 only if it's really needed.
2390 * frame.h (enum output_method): Remove output_mac member since
2391 it's a leftover from the deleted code.
2392 * frame.c (Fframep): Adjust user here ...
2393 * terminal.c (Fterminal_live_p): ... and here.
2394 * coding.c (Qmac): Now here because it's only used to denote
2395 end-of-line encoding type.
2396 (syms_of_coding): DEFSYM it.
2397 * frame.h (Qmac): Remove duplicated declaration.
2399 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
2401 * window.c (select_window_1): Now static, since it's used only here.
2403 2012-12-25 Eli Zaretskii <eliz@gnu.org>
2405 * window.c (window_body_cols): Subtract display margins from the
2406 window body width on TTYs as well. See
2407 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
2408 for the original report.
2410 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
2412 * xdisp.c (redisplay_window): Remove inner local variable
2413 because the outer shadowed one has the same meaning.
2414 * xterm.h (struct x_output): Remove toolbar_detached member since it's
2416 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
2417 (xg_create_tool_bar): Adjust users.
2419 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
2421 * buffer.h (BUF_COMPACT): New macro to follow the common style.
2422 * buffer.c (Fget_buffer_create): Use it to set compact field of
2423 struct buffer_text to avoid accessing an uninitialized value
2424 when compact_buffer is called for the first time.
2425 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
2426 (Fset_buffer_modified_p): Use buffer_window_count to check
2427 whether the buffer is displayed in some window.
2428 * xdisp.c (message_dolog): Likewise.
2430 2012-12-23 Eli Zaretskii <eliz@gnu.org>
2432 * w32.c (acl_set_file): If setting the file security descriptor
2433 fails, and the new DACL is identical to the existing one, silently
2434 return success. This fixes problems for users backing up their
2435 own files without having the necessary privileges for setting
2436 security descriptors.
2438 * w32proc.c (reader_thread): Do not index fd_info[] with negative
2440 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
2441 after WaitForSingleObject returns normally. This expedites reader
2442 thread shutdown when delete_child triggers it.
2443 (reap_subprocess): More accurate commentary for why we call
2444 delete_child only when cp->fd is negative.
2446 * w32.c (sys_close): Do not call delete_child on a subprocess
2447 whose handle is not yet closed. Instead, set its file descriptor
2448 to a negative value, so that reap_subprocess will call
2449 delete_child on that subprocess when its SIGCHLD arrives.
2450 This avoids closing handles used for communications between sys_select
2451 and reader_thread, which doesn't give sys_select a chance to
2452 notice that the process exited and invoke the SIGCHLD handler for
2455 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
2457 * nsfns.m (Fns_do_applescript): Run event loop until script has
2458 been executed (Bug#12969).
2459 (ns_run_ascript): Chech as_script for nil, set to nil after
2462 2012-12-22 Martin Rudalics <rudalics@gmx.at>
2464 * window.c (Fselect_window): Reword doc-string (Bug#13248).
2466 2012-12-22 Eli Zaretskii <eliz@gnu.org>
2468 * w32term.c (w32fullscreen_hook): New function.
2469 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
2471 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2473 * fileio.c (Finsert_file_contents): Doc fix.
2475 * w32proc.c (new_child, delete_child, find_child_pid): For a
2476 subprocess, consider its slot being in use as long as its process
2477 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2478 slot when a new process is started immediately after killing
2479 another one, without waiting enough time for the first process to
2480 be reaped and resources allocated for it be orderly freed.
2482 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2484 2012-12-21 Chong Yidong <cyd@gnu.org>
2486 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
2488 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
2490 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2492 * w32.c (get_name_and_id): Always pass NULL as the first argument
2493 of lookup_account_sid. Avoids crashes with UNC file names that
2494 refer to DFS domains, not to specific machine names. (Bug#12621)
2495 Remove now unused argument FNAME; all callers changed.
2496 (get_file_owner_and_group): Remove now unused argument FNAME; all
2499 2012-12-21 Chong Yidong <cyd@gnu.org>
2501 * editfns.c (Finsert_char): Since read-char-by-name now signals an
2502 error for invalid chars, don't check for a nil return value.
2504 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2506 Avoid calls to CHAR_TO_BYTE if byte position is known.
2507 * editfns.c (make_buffer_string_both): Use move_gap_both.
2508 (Fbuffer_string): Use make_buffer_string_both.
2509 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
2511 (buf_bytepos_to_charpos): Likewise.
2512 (charpos_to_bytepos): Remove.
2513 * fileio.c (Finsert_file_contents): Use move_gap_both.
2514 * search.c (Freplace_match): Likewise.
2515 * process.c (process_send_region): Likewise. Use convenient
2516 names for byte positions.
2517 * lisp.h (charpos_to_bytepos): Remove prototype.
2518 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
2519 * insdel.c (move_gap): Likewise.
2521 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
2523 * xdisp.c (redisplay_internal): Remove now-unused local.
2525 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
2527 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
2528 (redisplay_internal): Don't bother selecting the frame to get the
2529 proper value of frame-local variables (bug#13225).
2531 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2533 * textprop.c (set_text_properties_1): Do not allow NULL interval.
2534 Rename 4th argument since it may be buffer or string. Adjust comment.
2535 * intervals.c (graft_intervals_info_buffer): Find an interval here.
2537 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
2539 * coding.c (Fdetect_coding_region): Do not check start and end with
2540 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
2541 (code_convert_region): Likewise.
2543 2012-12-18 Eli Zaretskii <eliz@gnu.org>
2545 * w32.c (acl_get_file, acl_set_file): Run the file name through
2546 map_w32_filename, and resolve any symlinks in the file name, like
2548 (acl_set_file): Call revert_to_self, if any privileges were
2551 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
2553 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
2554 ($(BLD)/w32.$(O)): Update dependencies.
2556 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
2558 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
2559 propagate redisplay's scrolling (if any) to the right window.
2560 (redisplay_internal): Use ensure_selected_frame.
2561 (display_mode_lines): Complete last fix.
2562 * window.c (select_window_1): New func, extracted from select_window.
2563 (select_window): Use it.
2564 * window.h (select_window_1): Declare.
2566 2012-12-17 Eli Zaretskii <eliz@gnu.org>
2568 Emulate Posix ACL APIs on MS-Windows.
2569 * w32.c: Include sddl.h and sys/acl.h.
2570 (SDDL_REVISION_1): Define if not already defined.
2571 (g_b_init_get_security_descriptor_dacl)
2572 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
2573 (g_b_init_is_valid_security_descriptor)

2586 (acl_free, acl_get_file, acl_set_file): New functions.
2588 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
2590 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
2592 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2593 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2594 for some of that bug's symptoms can now cause Emacs to abort.
2595 Remove the workaround.
2596 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2597 The bug that caused SIGCHLD to get lost has been fixed, and the
2598 workaround for it can now cause Emacs to abort.
2600 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2602 * sysdep.c (emacs_abort): Bump backtrace size to 40.
2603 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
2604 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
2606 2012-12-16 Romain Francoise <romain@orebokech.com>
2608 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
2609 (Fcopy_file): Change last arg to `preserve_extended_attributes'
2610 and copy ACL entries of file in addition to SELinux context if set.
2611 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
2613 * Makefile.in (LIBACL_LIBS): New macro.
2616 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
2618 * fileio.c (internal_delete_file): Use bool for boolean.
2620 2012-12-15 Eli Zaretskii <eliz@gnu.org>
2622 Fix bug #13079 on MS-Windows with temp files not being deleted.

2625 (register_child): First argument is now pid_t.
2626 (record_infile, record_pending_deletion): New prototypes.
2628 * w32proc.c (new_child): Initialize input_file and
2629 pending_deletion members of the child.
2630 (delete_child): Delete the child's temporary input file, if any,
2631 that is pending deletion.
2632 (register_child): First argument is now pid_t.
2633 (record_infile, record_pending_deletion): New functions.
2634 (reap_subprocess): Fix a typo in DebPrint string.
2635 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
2637 * fileio.c (internal_delete_file): Return an int again: non-zero
2638 if delete-file succeeds, zero otherwise.
2640 * lisp.h (internal_delete_file): Adjust prototype.
2642 * callproc.c (Fcall_process): Don't overwrite infile with result
2644 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
2645 asynchronous subprocess, record the name of the input file name,
2647 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
2648 delete the file, record it as pending deletion when the subprocess
2651 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2653 * editfns.c [HAVE_PWD_H]: Include grp.h.
2655 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
2657 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
2659 Fix permissions bugs with setgid directories etc. (Bug#13125)
2660 * dired.c (Ffile_attributes): Return t as the 9th attribute,
2661 to mark it as a placeholder. The old value was often wrong.
2662 The only user of this attribute has been changed to use
2663 file-ownership-preserved-p instead, with its new group arg.
2664 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
2666 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

2671 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2673 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
2674 try to get accurate owner and group information from NT file
2675 security APIs. This is to make most callers of 'stat' and
2676 'lstat', which don't need that information, much faster.
2678 * dired.c (Ffile_attributes) [WINDOWSNT]:
2679 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2680 owner and group information from 'lstat'.
2682 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2684 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2685 as that confuses set-auto-coding, so insist on the head-read
2686 returning the full 1024 bytes. Let lseek compute the tail offset;
2687 less work for us. Do not ignore I/O errors when reading the tail.
2689 * xdisp.c: Minor style fixes.
2690 (init_iterator): Hoist assignment out of if-expression.
2691 (markpos_of_region): Callers now test for sign, not for -1.
2693 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
2695 Minor redisplay optimization when the region length is zero.
2696 * xdisp.c (markpos_of_region): New function.
2697 (init_iterator): Do not highlight the region of zero length.
2698 (redisplay_window): Check whether the region is of non-zero length.
2699 (try_cursor_movement): Allow if the region length is zero.
2700 (try_window_reusing_current_matrix, try_window_id): Likewise.
2702 2012-12-13 Eli Zaretskii <eliz@gnu.org>
2704 * search.c (search_buffer): Check the inverse translations of each
2705 character in pattern when the buffer being searched is unibyte.
2708 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2710 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
2711 files, fixing a regression from 24.2.
2712 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
2714 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2716 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2717 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2718 Remove unnecessary S_ISLNK test, as (contra the comments) this
2719 function can't copy symlinks. Improve quality of error message
2720 when attempting to copy files that are neither regular files nor
2723 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>
2725 * dispnew.c (set_window_cursor_after_update): Use clip_to_bounds.
2726 * gtkutil.c (xg_set_toolkit_scroll_bar_thumb):
2727 * window.c (Frecenter):
2728 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
2729 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
2731 2012-12-12 Daniel Colascione <dancol@dancol.org>
2733 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
2734 the dumped Emacs is not a sparse file, greatly improving Cygwin
2735 "make bootstrap" performance.
2737 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
2739 * inotify.c (inotify_callback): Generate an Emacs event for every
2740 incoming inotify event.
2742 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2744 * xdisp.c (handle_face_prop): Fix logic of computing
2745 it->start_of_box_run_p.
2746 (append_space_for_newline): If the glyph row is R2L, reset the
2747 iterator's end_of_box_run_p flag before prepending the space glyph.
2748 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
2749 iterator's start_of_box_run_p flag before prepending the stretch.
2750 (append_glyph, produce_image_glyph, append_composite_glyph)
2751 (append_stretch_glyph, append_glyphless_glyph): Reverse the
2752 left_box_line_p and right_box_line_p flags of the glyph for R2L
2753 glyph rows. (Bug#13011)
2755 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
2757 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
2758 if changed buffer is not shown in a window.
2759 * insdel.c (prepare_to_modify_buffer): Likewise.
2760 * window.c (replace_buffer_in_windows_safely): Do nothing
2761 if buffer is not shown in a window.

2765 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2767 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
2768 encoded_file_name, which is what it is.
2770 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
2772 Consistently use marker_position and marker_byte_position.
2773 * fringe.c (Ffringe_bitmaps_at_pos):

2953 * dbusbind.c (Fdbus_init_bus):
2955 * xterm.c (x_term_init):

2966 no longer needed here.
2967 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:

2969 (set_time_zone_rule): Maintain the TZ=value string separately.
2970 (syms_of_editfns): Don't initialize initial_tz;
2971 init_editfns now does it.
2972 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
2973 * lisp.h (xputenv): New decl.
2975 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>

2991 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
2992 Remove USG and vlimit methods; no longer used these days.
2993 Add #error catchall just in case.
2995 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
2996 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
2997 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.

3019 This will cause a production Emacs to dump core instead of
3022 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3024 * frame.c (make_frame): Do not set window's buffer to t.
3025 * window.c (Fsplit_window_internal): Likewise. Previously it was
3026 used to indicate that the window is being set up. Now we use
3027 set_window_buffer for all new windows, so the condition in ...
3028 (Fset_window_buffer): ... is always true and can be removed.
3030 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3032 Convenient macro to check whether the buffer is hidden.
3033 * buffer.h (BUFFER_HIDDEN_P): New macro.

3060 * callproc.c, process.h (record_kill_process):
3061 New function, containing part of the old call_process_kill.
3062 (call_process_kill): Use it.
3063 This does not change call_process_kill's behavior.
3064 * process.c (Fdelete_process): Use record_kill_process to fix a
3065 race condition that could cause Emacs to lose track of a child.
3067 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3069 Avoid code duplication between prev_frame and next_frame.
3070 * frame.c (candidate_frame): New function. Add comment.
3071 (prev_frame, next_frame): Use it. Adjust comment.
3073 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3075 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
3076 fails, signal an error instead of continuing with an empty
3078 Encode expanded temp file pattern before passing it to mkstemp or
3081 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
3082 Encode the file name before passing it to dostounix_filename, in
3083 case it will downcase it (under w32-downcase-file-names).
3086 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
3088 Minor call-process cleanups.
3089 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
3090 at the same time as other platforms, to simplify analysis.
3091 No need for fd0_volatile since we have synch_process_fd.
3092 Avoid needless emacs_close; arg is always negative.
3094 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
3096 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous

3101 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
3102 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer

3108 member. Adjust users. Convert term_initted, delete_in_insert_mode,
3109 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
3110 members to a bitfields.
3112 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
3114 Don't let call-process be a zombie factory (Bug#12980).
3115 Fixing this bug required some cleanup of the signal-handling code.
3116 As a side effect, this change also fixes a longstanding rare race
3117 condition whereby Emacs could mistakenly kill unrelated processes,
3118 and it fixes a bug where a second C-g does not kill a recalcitrant
3119 synchronous process in GNU/Linux and similar platforms.
3120 The patch should also fix the last vestiges of Bug#9488,
3121 a bug which has mostly been fixed on the trunk by other changes.
3122 * callproc.c, process.h (synch_process_alive, synch_process_death)
3123 (synch_process_termsig, sync_process_retcode):
3124 Remove. All uses removed, to simplify analysis and so that
3125 less consing is done inside critical sections.
3126 * callproc.c (call_process_exited): Remove. All uses replaced
3127 with !synch_process_pid.
3128 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
3129 These take the role of what used to be in unwind-protect arg.
3131 (block_child_signal, unblock_child_signal):
3132 New functions, to avoid races that could kill innocent-victim processes.
3133 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
3134 (call_process_kill): Record killed processes as deleted, so that
3135 zombies do not clutter up the system. Do this inside a critical
3136 section, to avoid a race that would allow the clutter.
3137 (call_process_cleanup): Fix code so that the second C-g works again
3138 on common platforms such as GNU/Linux.
3139 (Fcall_process): Create the child process in a critical section,
3140 to fix a race condition. If creating an asynchronous process,
3141 record it as deleted so that zombies do not clutter up the system.
3142 Do unwind-protect for WINDOWSNT too, as that's simpler in the
3143 light of these changes. Omit unnecessary call to emacs_close
3144 before failure, as the unwind-protect code does that.
3145 * callproc.c (call_process_cleanup):
3146 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
3147 * process.c (record_deleted_pid): New function, containing
3148 code refactored out of Fdelete_process.
3149 (Fdelete_process): Use it.
3150 (process_status_retrieved): Remove. All callers changed to use
3151 child_status_change.
3152 (record_child_status_change): Remove, folding its contents into ...
3153 (handle_child_signal): ... this signal handler. Now, this
3154 function is purely a handler for SIGCHLD, and is not called after
3155 a synchronous waitpid returns; the synchronous code is moved to
3156 wait_for_termination. There is no need to worry about reaping
3157 more than one child now.
3158 * sysdep.c (get_child_status, child_status_changed): New functions.
3159 (wait_for_termination): Now takes int * status and bool
3160 interruptible arguments, too. Do not record child status change;
3161 that's now the caller's responsibility. All callers changed.
3162 Reimplement in terms of get_child_status.
3163 (wait_for_termination_1, interruptible_wait_for_termination):
3164 Remove. All callers changed to use wait_for_termination.
3165 * syswait.h: Include <stdbool.h>, for bool.
3166 (record_child_status_change, interruptible_wait_for_termination):
3168 (record_deleted_pid, child_status_changed): New decls.
3169 (wait_for_termination): Adjust to API changes noted above.
3171 * bytecode.c, lisp.h (Qbytecode): Remove.
3172 No longer needed after 2012-11-20 interactive-p changes.
3174 2012-12-03 Eli Zaretskii <eliz@gnu.org>
3176 * xdisp.c (redisplay_window): If the cursor is visible, but inside
3177 the scroll margin, move point outside the margin. (Bug#13055)
3179 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
3181 * gtkutil.c (my_log_handler): New function.
3182 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
3184 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3186 * lisp.h (modify_region): Rename to...
3187 (modify_region_1): ...new prototype.
3188 * textprop.c (modify_region): Now static. Adjust users.
3189 * insdel.c (modify_region): Rename to...
3190 (modify_region_1): ...new function to work with current buffer.
3191 Adjust comment and users. Use true and false for booleans.
3193 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3195 * alloc.c (free_save_value): New function.
3196 (safe_alloca_unwind): Use it.
3197 * lisp.h (free_save_value): New prototype.
3198 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
3200 (save_excursion_restore): Adjust to match saved data structure.
3201 Use free_save_value to offload some work from GC. Drop obsolete
3204 2012-12-03 Chong Yidong <cyd@gnu.org>
3206 * fileio.c (Vauto_save_list_file_name): Doc fix.
3208 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
3210 * w32fns.c: Remove prototype of atof.
3211 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
3213 (file_dialog_callback): Make it UINT_PTR.
3215 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
3218 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3219 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
3222 2012-12-03 Glenn Morris <rgm@gnu.org>
3224 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
3226 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
3228 Fix xpalloc confusion after memory is exhausted.
3229 * alloc.c (xpalloc): Comment fix.
3230 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
3231 and signals an error, do not clear charset_table_size, as
3232 charset_table is still valid.
3233 * doprnt.c (evxprintf): Clear *BUF after freeing it.
3235 Use execve to avoid need to munge environ (Bug#13054).
3236 * callproc.c (Fcall_process):
3237 * process.c (create_process):
3238 Don't save and restore environ; no longer needed.
3239 * callproc.c (child_setup):
3240 Use execve, not execvp, to preserve environ.
3242 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
3244 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
3246 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3248 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
3249 display for sliced images (Bug#10500).
3251 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
3253 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
3255 * doc.c (Fdocumentation): Re-add handling of function-documentation,
3256 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
3258 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
3260 * xdisp.c (window_outdated): Remove eassert since it hits
3261 some suspicious corner cases (see Bug#13007 and Bug#13012).
3262 (mode_line_update_needed): New function.
3263 (redisplay_internal, redisplay_window): Use it.
3264 (ensure_selected_frame): New function.
3265 (redisplay_internal, unwind_redisplay): Use it.
3266 (redisplay_internal): Move comment about buffer_shared...
3267 (buffer_shared_and_changed): ...near to its real use.
3269 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
3271 * callproc.c (Fcall_process): Don't misreport vfork failure.
3273 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
3275 * callproc.c (Fcall_process): Fix vfork portability problems.
3276 Do not assume that fd[0], count, filefd, and save_environ survive
3277 vfork. Fix bug whereby wrong errno value could be reported for
3278 pipe failure. Some minor cleanups, too, as follows. Move buf and
3279 bufsize to the context where they're needed. Change new_argv to
3280 be of type char **, as this is more convenient and avoids casts.
3281 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
3282 Now local constants, not macros.
3284 2012-11-18 Kenichi Handa <handa@gnu.org>
3286 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
3287 for the variable "f".
3289 2012-11-13 Kenichi Handa <handa@gnu.org>
3291 * font.c (font_unparse_xlfd): Exclude special characters from the
3292 generating XLFD name.
3294 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
3296 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.
3297 * dired.c (stat_uname, stat_gname):
3298 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
3300 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

3304 * fileio.c (Fcopy_file): Assume EISDIR is defined.
3305 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
3306 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
3307 * lread.c (readbyte_from_file): Assume EINTR is defined.
3308 * process.c (wait_reading_process_output, send_process) [subprocesses]:
3309 Assume EIO and EAGAIN are defined.
3310 * unexcoff.c (write_segment): Assume EFAULT is defined.
3312 2012-11-27 Eli Zaretskii <eliz@gnu.org>
3314 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
3317 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
3318 highlighting on the frame was cleared. Prevents assertion
3319 violations when repeatedly clicking on the "Top" link of the
3320 "bread-crumbs" in Info buffers.
3322 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
3324 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
3326 2012-11-24 Ken Brown <kbrown@cornell.edu>
3328 * keyboard.c (HAVE_MOUSE):
3329 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
3330 were always defined.
3332 2012-11-24 Eli Zaretskii <eliz@gnu.org>
3334 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
3335 between bpos_covered and bpos_max. This fixes cursor display when
3336 several display strings follow each other.
3338 * .gdbinit (pgx): If the glyph's object is a string, display the
3339 pointer to string data, rather than the value of the string object
3340 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
3342 * indent.c (Fvertical_motion): If the starting position is covered
3343 by a display string, return to one position before that, to avoid
3344 overshooting it inside move_it_to. (Bug#12930)
3346 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
3348 * frame.h (struct frame): Remove display_preempted member
3349 since all users are dead long ago.
3350 * nsterm.h (struct x_output): Use the only dummy member.
3351 * w32menu.c (pending_menu_activation): Remove since not
3353 (set_frame_menubar): Adjust user.
3354 * w32term.h (struct x_output): Drop outdated #if 0 code.
3355 (struct w32_output): Use bitfields for explicit_parent,
3356 asked_for_visible and menubar_active members.
3357 Drop unused pending_menu_activation member.
3358 * xterm.h (struct x_output): Drop outdated #if 0 code.
3359 Use bitfields for explicit_parent, asked_for_visible,
3360 has_been_visible and net_wm_state_hidden_seen members.
3362 2012-11-23 Eli Zaretskii <eliz@gnu.org>
3364 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
3365 of a literal "/". (Bug#12955)
3366 (gl-stamp): Invoke fc.exe directly, not through cmd.
3368 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
3370 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
3371 * dired.c: Assume HAVE_DIRENT_H.
3372 (NAMLEN): Remove, replacing with ...
3373 (dirent_namelen): New function. All uses changed. Use the GNU macro
3374 _D_EXACT_NAMELEN if available, as it's faster than strlen.
3375 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
3376 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
3377 * makefile.w32-in (DIR_H): Remove. All uses replaced with
3379 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
3380 * ndir.h: Rename to ../nt/inc/dirent.h.
3381 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
3382 Do not include <dirent.h>; no longer needed.
3383 * w32.c: Include <dirent.h> rather than "ndir.h".
3385 2012-11-23 Chong Yidong <cyd@gnu.org>
3387 * xftfont.c (xftfont_open): Remove duplicate assignment.
3389 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3391 * alloc.c (Fgarbage_collect): Unblock input after clearing
3392 gc_in_progress to avoid note_mouse_highlight glitch with GC.
3393 * frame.h (FRAME_MOUSE_UPDATE): New macro.
3394 * msdos.c (IT_frame_up_to_date): Use it here...
3395 * w32term.c (w32_frame_up_to_date): ...here...
3396 * xterm.c (XTframe_up_to_date): ...and here...
3397 * nsterm.m (ns_frame_up_to_date): ...but not here.
3398 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
3400 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
3401 Do not check whether GC is in progress.
3403 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3405 * xdisp.c (window_buffer_changed): New function.
3406 (update_menu_bar, update_tool_bar): Use it to
3407 simplify large 'if' statements.
3408 (redisplay_internal): Generalize commonly used
3409 'tail' and 'frame' local variables.
3411 2012-11-22 Eli Zaretskii <eliz@gnu.org>
3413 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
3414 with Windows system header.
3416 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
3418 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
3419 * alloc.c: Assume unistd.h exists.
3420 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
3421 * sysdep.c (get_current_dir_name): Assume getcwd exists.
3422 (getwd) [USG]: Remove; no longer needed.
3423 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
3424 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
3425 * w32.h (getcwd): Remove decl.
3427 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
3429 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
3430 Make it set selected_window as well.
3431 (update_tool_bar): Use it.
3433 2012-11-21 Ken Brown <kbrown@cornell.edu>
3435 * emacs.c (main): Set the G_SLICE environment variable for all
3436 Cygwin builds, not just GTK builds. See
3437 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
3439 2012-11-21 Eli Zaretskii <eliz@gnu.org>
3441 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3442 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
3443 Define for the MSVC compiler.
3445 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
3447 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
3448 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
3449 dostounix_filename. Prevents crashes down the road, because
3450 dostounix_filename assumes it gets a unibyte string.
3451 Reported by Michel de Ruiter <michel@sentient.nl>, see
3452 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
3454 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

3458 * lread.c (init_obarray): Set `function' fields to Qnil.
3459 * eval.c (Fcommandp): Ignore Qunbound.
3460 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
3461 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
3462 Test NILP rather than Qunbound.
3463 (Ffmakunbound): Set to Qnil.
3464 (Fsymbol_function): Never signal an error.
3465 (Finteractive_form): Ignore Qunbound.
3467 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
3469 * eval.c (interactive_p): Remove no-longer-used decl.
3471 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
3473 * xdisp.c (buffer_shared): Adjust comment.
3474 (buffer_shared_and_changed): New function.
3475 (prepare_menu_bars, redisplay_internal): Use it to
3476 decide whether all windows or frames should be updated.
3477 (window_outdated): New function.
3478 (text_outside_line_unchanged_p, redisplay_window): Use it.
3479 (redisplay_internal): Likewise. Fix indentation.
3481 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
3483 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
3484 (syms_of_eval): Remove corresponding defsubr.
3485 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
3487 2012-11-19 Daniel Colascione <dancol@dancol.org>
3489 * w32fns.c (Fx_file_dialog):
3490 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
3491 cygwin_convert_file_name*.
3493 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
3494 Rename cygwin_convert_path* to cygwin_convert_file_name*.
3496 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
3498 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3500 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3502 * w32select.c: Include w32common.h before w32term.h, so that
3503 windows.h gets included before w32term.h uses some of its
3504 features, see below.
3506 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3508 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
3510 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
3512 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
3514 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
3515 (ns_select): Return at once if events are held (Bug#12834).
3517 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3519 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3520 Needed following 2012-10-20 change. (Bug#12902)
3522 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3524 * w32proc.c (waitpid): Remove unused label get_result.
3526 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3528 * makefile.w32-in (SYSWAIT_H): New macro.
3529 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3530 ($(BLD)/sysdep.$(O)): Update dependencies.
3532 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3534 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
3535 * callproc.c (relocate_fd): Assume F_DUPFD.
3536 * emacs.c, term.c (O_RDWR): Remove.
3537 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3538 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3539 * nsterm.m: Assume <fcntl.h> exists.
3540 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3541 (create_pty, Fmake_network_process, server_accept_connection)
3542 (wait_reading_process_output, init_process_emacs):
3544 (wait_reading_process_output): Put in a special case for WINDOWSNT
3545 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3546 It's not clear this is needed, but it's a more-conservative change.
3547 (create_process): Assume FD_CLOEXEC.
3548 (create_process, create_pty): Assume O_NOCTTY.
3549 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3550 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3551 Omit if not DOS_NT, since F_GETFL is not defined there.
3552 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3553 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3555 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3556 lack it, since gnulib guarantees this.
3557 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3559 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3561 * w32.c (faccessat): Pretend that directories have the execute bit
3562 set. Emacs expects that, e.g., in files.el:cd-absolute.
3564 * w32proc.c (create_child): Don't clip the PID of the child
3565 process to fit into an Emacs integer, as this is no longer a
3567 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3568 reaping only the process specified by PID argument, if that is
3569 positive. Use PID instead of dead_child to know which process to
3570 reap. Wait for the child to die only if WNOHANG is not in
3572 (sys_select): Don't set dead_child.
3574 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3575 as it is no longer needed.
3577 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3579 (record_child_status_change): Remove the setting of
3580 record_at_most_one_child for the !WNOHANG case.
3582 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3584 Fix problems in ns port found by static checking.
3585 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3586 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3587 not to process group.
3588 (ns_select): Use emacs_write, not write, as that's more robust
3589 in the presence of signals.
3590 (fd_handler:): Check for read errors.
3592 2012-11-16 Glenn Morris <rgm@gnu.org>
3594 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3596 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3598 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3600 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3602 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3603 use the same value of thread handle.
3604 (start_timer_thread): If the timer thread exited (due to error),
3605 clean up by closing the two handles it used. Duplicate the caller
3606 thread's handle here, so it gets duplicated only once, when
3607 launching the timer thread. Set priority of the timer thread, not
3609 (getitimer): Don't duplicate the caller thread's handle here.
3612 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3614 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3617 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3619 Remove no-longer-used pty_max_bytes variable.
3620 * process.c (pty_max_bytes): Remove; unused.
3621 (send_process): Do not set it.
3623 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3625 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3626 Update dependencies.
3628 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3630 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3631 This follows up on the 2012-09-29 patch that removed indirection
3632 for the 'function' field. Reported by Sergey Vinokurov in
3633 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3635 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3637 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3638 different name, as the MS runtime does not have such a function,
3639 and probably never will.) All callers changed. Ignore DIRFD
3640 value if PATH is an absolute file name, to match Posix spec
3641 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3644 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3646 * xdisp.c (echo_area_display, redisplay_internal):
3647 Omit redundant check whether frame_garbaged is set.
3649 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3651 Use faccessat, not access, when checking file permissions (Bug#12632).
3652 This fixes a bug that has been present in Emacs since its creation.
3653 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3654 which must set some sort of record. (Torek's bug report was against
3655 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3656 same common flaw.) See Torek's Usenet posting
3657 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3658 Posted: Fri Apr 8 14:18:56 1983.
3659 * Makefile.in (LIB_EACCESS): New macro.
3661 * callproc.c (init_callproc):
3662 * charset.c (init_charset):
3663 * fileio.c (check_existing, check_executable, check_writable)
3665 * lread.c (openp, load_path_check):
3666 * process.c (allocate_pty):
3668 Use effective UID when checking permissions, not real UID.
3669 * callproc.c (init_callproc):
3670 * charset.c (init_charset):
3671 * lread.c (load_path_check, init_lread):
3672 Test whether directories are accessible, not merely whether they exist.
3673 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3674 * fileio.c (check_existing, check_executable, check_writable)
3676 Use symbolic names instead of integers for the flags, as they're
3678 (check_writable): New arg AMODE. All uses changed.
3679 Set errno on failure.
3680 (Ffile_readable_p): Use faccessat, not stat + open + close.
3681 (Ffile_writable_p): No need to call check_existing + check_writable.
3682 Just call check_writable and then look at errno. This saves a syscall.
3683 dir should never be nil; replace an unnecessary runtime check
3684 with an eassert. When checking the parent directory of a nonexistent
3685 file, check that the directory is searchable as well as writable, as
3686 we can't create files in unsearchable directories.
3687 (file_directory_p): New function, which uses 'stat' on most platforms
3688 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3689 (Ffile_directory_p, Fset_file_times): Use it.
3690 (file_accessible_directory_p): New function, which uses a single
3691 syscall for efficiency.
3692 (Ffile_accessible_directory_p): Use it.
3693 * xrdb.c (file_p): Use file_directory_p.
3694 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3695 * lread.c (openp): When opening a file, use fstat rather than
3696 stat, as that avoids a permissions race. When not opening a file,
3697 use file_directory_p rather than stat.
3698 (dir_warning): First arg is now a usage string, not a format.
3699 Use errno. All uses changed.
3700 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3701 that merely introduced a race.
3702 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3703 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3704 and similarly for the other O_* flags.
3705 * w32.c (sys_faccessat): Rename from sys_access and switch to
3706 faccessat's API. All uses changed.
3707 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3708 (magic_db): Rename from magic_file_p.
3709 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3710 char *, so that we don't have to test for file existence
3711 separately from opening the file for reading. This removes a race
3712 fixes a permission-checking problem, and simplifies the code.
3714 (file_p): Remove; no longer needed.
3716 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3718 Omit glyphs initialization at startup.

3729 passed to pint2str and pint2hrstr to be at most the size of the
3730 frame's decode_mode_spec_buffer. This avoids crashes with very
3731 large values of FIELD_WIDTH argument to decode_mode_spec.
3734 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3736 Fix a race with verify-visited-file-modtime (Bug#12863).
3737 Since at least 1991 Emacs has ignored an mtime difference of no
3738 more than one second, but my guess is that this was to work around
3739 file system bugs that were fixed long ago. Since the race is
3740 causing problems now, let's remove that code.
3741 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3742 whose time stamp is off by no more than a second. Insist that the
3743 file time stamps match exactly.

3763 * xmenu.c (menubar_id_to_frame): Likewise.
3764 * xselect.c (frame_for_x_selection): Likewise.
3765 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3766 (x_window_to_menu_bar): Likewise.
3767 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3769 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3771 * data.c (Qdefalias_fset_function): Now static.
3773 Another tweak to vectorlike_header change.
3774 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3775 Remove, and replace all uses with ...
3776 (next_in_free_list, set_next_in_free_list):
3777 New functions, which respect C's aliasing rules better.
3779 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3781 * window.c (list4i): Rename from 'quad'. All uses changed.
3782 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3784 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3786 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3787 warning about mixing declarations and code in ISO C90.
3789 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3791 * window.c (Fsplit_window_internal): Set combination limit of
3792 new parent window to t iff Vwindow_combination_limit is t;
3793 fixing a regression introduced with the change from 2012-09-22.
3794 (Fset_window_combination_limit): Fix doc-string.
3796 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3798 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3799 amount when the scroll margins are too large. When scrolling
3800 backwards in the buffer, give up if cannot reach point or the
3801 scroll margin within a reasonable number of screen lines.
3802 Fixes point position in window under scroll-up/down-aggressively when
3803 point is positioned many lines beyond the window top/bottom.
3806 * ralloc.c (relinquish): If real_morecore fails to return memory
3807 to the system, don't crash; instead, leave the last heap
3808 unchanged and return. (Bug#12774)

3817 (Finteractive_form): Simplify.
3818 (Fquo): Don't insist on having at least 2 arguments.
3819 (Qdefalias_fset_function): New var.
3821 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3823 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
3825 * nsfont.m (Qcondensed, Qexpanded): New variables.

3829 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3831 Fix recently introduced crash on MS-Windows (Bug#12839).
3832 * w32term.h (struct scroll_bar): Use convenient header.
3833 (SCROLL_BAR_VEC_SIZE): Remove.
3834 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3836 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3838 Tweak last vectorlike_header change.
3839 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3840 vectorlike object on the free list. This is introduced to avoid
3841 some (but not all) pointer casting and aliasing problems, see
3842 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3843 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

3847 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3849 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3850 been removed, so remove them here also.
3852 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3854 * doc.c (Fdocumentation): Handle new property
3855 dynamic-docstring-function to replace the old ad-advice-info.
3857 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
3859 * fns.c (Qeql, hashtest_eq): Now static.
3861 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3863 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
3864 * fns.c (hashfn_eq, hashfn_eql, sxhash):
3865 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.

3872 * lisp.h (sxhash_combine): New inline function, with the contents
3873 of the old SXHASH_COMBINE.

3875 special hash function containing a comparison that always yields 1.
3877 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3879 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3880 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3881 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3884 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3886 * image.c (xpm_make_color_table_h): Fix compiler error because
3887 make_hash_table changed.
3889 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
3891 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3893 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3895 Use ad-hoc comparison function for the profiler's hash-tables.
3896 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3897 (make_log): Use them.
3898 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3899 call Fequal any more.

3908 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
3909 (hash_lookup, hash_remove_from_table): Move assertion checking of
3910 hashfn result here. Check hash-equality before calling cmpfn.

3928 Shrink struct vectorlike_header to the only size field.
3929 * lisp.h (enum pvec_type): Avoid explicit enum member values.
3931 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and

3950 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3951 (large_vectors): Change type to struct large_vector.
3952 (allocate_vector_from_block): Simplify.
3953 (PSEUDOVECTOR_NBYTES): Replace with...

3959 (allocate_buffer): Use BUFFER_PVEC_INIT.
3960 (live_vector_p): Adjust to match large vector.
3961 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
3962 * buffer.h (struct buffer): Add next member.
3963 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):

3971 (xvecsize): New command.
3973 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3975 * keyboard.c (event_to_kboard): Do not dereference
3976 frame_or_window field of SELECTION_REQUEST_EVENT
3977 and SELECTION_CLEAR_EVENT events (Bug#12814).
3978 * xterm.h (struct selection_input_event): Adjust comment.
3980 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3982 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3983 such as Scroll Lock, if the respective keys are treated as
3984 function keys, not as modifiers. This avoids destroying non-ASCII
3985 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3987 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3989 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3991 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3993 Restore some duplicate definitions (Bug#12814).
3994 This undoes part of the 2012-11-03 changes. Some people build
3995 with plain -g rather than with -g3, and they need the duplicate
3996 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3997 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3998 Define as macros, as well as as enums or as constants.
4000 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
4002 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
4003 to keypad keys (Bug#12816).
4005 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4007 Minor adjustments of recently-changed frame functions.
4008 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
4009 known to be a frame (we're in the FRAMEP branch).
4010 * lisp.h (Qframep): Remove decl. frame.h declares this.
4011 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
4012 since they're meant for Lisp fixnum values.
4014 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4016 * window.c (Fwindow_combination_limit): Revert to the only
4017 required argument and adjust docstring as suggested in
4018 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
4019 by Martin Rudalics <rudalics@gmx.at>.
4021 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>

4052 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
4053 (Fframe_face_alist): Use decode_live_frame.

4061 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
4062 (Fwindow_line_height): Use it.
4063 (Fwindow_fringes): Use list3.
4064 (Fwindow_scroll_bars): Use list4.
4065 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
4066 (Fwindow_combination_limit): Allow zero number of arguments.
4068 2012-11-05 Eli Zaretskii <eliz@gnu.org>
4070 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
4072 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
4073 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
4074 file descriptor 2 for standard error. (Bug#12805)
4076 2012-11-05 Chong Yidong <cyd@gnu.org>
4078 * process.c (wait_reading_process_output): Revert previous change.
4080 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
4082 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
4083 This removes code that has been obsolete since around 1990.
4084 * callproc.c (Fcall_process):
4086 * process.c (create_process):
4087 * term.c (dissociate_if_controlling_tty):
4088 Assume setsid exists.
4089 * callproc.c (child_setup): Assume setpgid exists and behaves as
4090 per POSIX.1-1988 or later.
4091 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
4092 * emacs.c (shut_down_emacs):
4093 * sysdep.c (sys_suspend, init_foreground_group):
4094 Assume getpgrp behaves as per POSIX.1-1998 or later.
4095 * msdos.c (setpgrp): Remove.
4096 (tcgetpgrp, setpgid, setsid): New functions.
4097 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
4098 * term.c (no_controlling_tty): Remove; unused.
4099 * w32proc.c (setpgrp): Remove.
4100 (setsid, tcgetpgrp): New functions.
4102 Simplify by assuming __fpending.
4103 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
4104 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
4105 Do not assume that __fpending's result fits in int.
4107 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
4109 Remove EMACS_OUTQSIZE+sleep hack.
4110 * dispnew.c (update_frame_1): Remove hack for terminals slower
4111 than 2400 bps, which throttled Emacs by having it sleep.
4112 This code hasn't worked since at least 2007, when the multi-tty stuff
4113 was added, and anyway those old terminals are long dead.
4114 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
4115 without the dispnew.c change, as dispnew.c doesn't include systty.h.
4117 Fix data-loss with --version (Bug#9574).
4118 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
4119 as we can't assume that emacs_strerror is initialized, and strerror
4120 is good enough here.
4121 (main): Invoke atexit earlier, to catch earlier instances of
4122 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
4124 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
4126 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
4127 (keyDown): Remap keypad keys to X11 virtual key codes.

4132 * emacs.c: Include <close-stream.h>.
4133 (close_output_streams): New function.
4134 (main): Pass it to atexit, so that Emacs closes stdout and stderr
4135 and handles errors appropriately.
4136 (Fkill_emacs): Don't worry about flushing, as close_output_stream
4139 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
4140 The symptom is a diagnostic "GLib-WARNING **: In call to
4141 g_spawn_sync(), exit status of a child process was requested but
4142 SIGCHLD action was set to SIG_IGN and ECHILD was received by
4143 waitpid(), so exit status can't be returned." The diagnostic
4144 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
4145 The real bug is a race condition between Emacs and glib: Emacs
4146 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
4147 so that glib can't find it. Work around the bug by invoking
4148 waitpid only on subprocesses that Emacs itself creates.
4149 * process.c (create_process, record_child_status_change):
4150 Don't use special value -1 in pid field, as the caller now must
4151 know the pid rather than having the callee infer it.
4152 The inference was sometimes incorrect anyway, due to another race.
4153 (create_process): Set new 'alive' member if child is created.
4154 (process_status_retrieved): New function.
4155 (record_child_status_change): Use it.
4156 Accept negative 1st argument, which means to wait for the
4157 processes that Emacs already knows about. Move special-case code
4158 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
4159 processes that have already been waited for, by testing and
4160 clearing new 'alive' member.
4161 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
4162 now does this internally.
4163 (handle_child_signal): Let record_child_status_change do all
4164 the work, since we do not want to reap all exited child processes,
4165 only the child processes that Emacs itself created.
4166 * process.h (Lisp_Process): New boolean member 'alive'.
4168 Omit duplicate definitions no longer needed with gcc -g3.
4169 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
4170 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
4171 Define only as macros. There's no longer any need to also define
4172 these symbols as enums or as constants, since we now assume
4173 gcc -g3 when debugging.
4175 2012-11-03 Eli Zaretskii <eliz@gnu.org>
4177 * lisp.mk: Adjust comments to the fact that term/internal is now
4178 loaded from loadup.el.
4180 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
4181 (msdos_fatal_signal): New function.
4182 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
4185 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
4186 for GCC versions before 4.
4187 (emacs_raise): Define to call msdos_fatal_signal.
4189 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
4190 iterator when starting in the middle of a display or overlay
4193 2012-11-03 Chong Yidong <cyd@gnu.org>
4195 * process.c (wait_reading_process_output): Clean up the last
4198 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
4200 * process.c (wait_reading_process_output): Avoid a race condition
4201 with SIGIO delivery (Bug#11536).
4203 2012-11-03 Chong Yidong <cyd@gnu.org>
4205 * buffer.c (cursor_type): Untabify docstring.
4207 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4209 * frame.h (struct frame): Drop can_have_scroll_bars member
4210 which is meaningless for a long time. Adjust comments.
4211 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
4212 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
4214 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4216 * window.c (decode_next_window_args): Update window arg after
4217 calling decode_live_window and so fix crash reported at
4218 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
4219 by Juanma Barranquero <lekktu@gmail.com>.
4220 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
4221 * font.c (Ffont_at): Likewise.
4223 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
4225 * widget.c (resize_cb): New function.
4226 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
4227 (EmacsFrameResize): Check if all is up to date before changing frame
4230 2012-11-02 Eli Zaretskii <eliz@gnu.org>
4232 Implement backtrace output for fatal errors on MS-Windows.

4234 (BACKTRACE_LIMIT_MAX): New macro.
4235 (w32_backtrace): New function.
4236 (emacs_abort): Use w32_backtrace when the user chooses not to
4237 attach a debugger. Update the text of the abort dialog.
4239 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4241 Window-related stuff cleanup here and there.
4242 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
4243 Use decode_any_window.
4244 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
4245 * xdisp.c (Fformat_mode_line): Likewise.
4246 * font.c (Ffont_at): Use decode_live_window.
4247 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
4248 * window.c (decode_next_window_args): Likewise.
4249 (decode_any_window): Remove static.
4250 * window.h (decode_any_window): Add prototype.
4251 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
4252 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
4255 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4257 Remove pad from struct input_event.
4258 * termhooks.h (struct input_event): Remove padding field.
4260 * keyboard.c (event_to_kboard): Simplify because frame_or_window
4261 member is never cons for a long time. Adjust comment.
4262 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
4263 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
4264 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
4265 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
4267 2012-11-01 Eli Zaretskii <eliz@gnu.org>
4269 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
4271 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
4273 Fix crash when using Emacs as commit editor for git (Bug#12697).
4274 * callproc.c (setpgrp): Remove macro, as we now use setpgid
4275 and it is configured in conf_post.h.
4276 (Fcall_process): Don't invoke both setsid and setpgid; the former
4277 is enough, if it exists.
4278 * callproc.c (Fcall_process, child_setup):
4279 * process.c (create_process): Use setpgid.
4280 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
4282 * dispnew.c (init_display): Initialize the foreground group
4283 if we are running a tty display.
4284 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
4285 * lisp.h (init_foreground_group): New decl.
4286 * sysdep.c (inherited_pgroup): New static var.
4287 (init_foreground_group, tcsetpgrp_without_stopping)
4288 (narrow_foreground_group, widen_foreground_group): New functions.
4289 (init_sys_modes): Narrow foreground group.
4290 (reset_sys_modes): Widen foreground group.
4292 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
4294 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
4296 2012-10-31 Martin Rudalics <rudalics@gmx.at>
4298 * minibuf.c (read_minibuf): Restore current buffer since
4299 choose_minibuf_frame calling Fset_frame_selected_window may
4300 change it (Bug#12766).
4302 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
4304 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
4306 2012-10-30 Kenichi Handa <handa@gnu.org>
4308 * font.c (Ffont_at): If WINDOW is specified and it is not
4309 displaying the current buffer, signal an error.
4311 2012-10-29 Daniel Colascione <dancol@dancol.org>
4313 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
4314 In preparation for fixing bug#12739, move these functions from
4317 * coding.h, coding.c: ... to here, and compile them only when
4318 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
4319 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
4321 2012-10-28 Eli Zaretskii <eliz@gnu.org>
4323 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
4324 (timer_loop, getitimer, setitimer): Use it instead of
4325 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
4327 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
4330 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
4332 * nsterm.m (NO_APPDEFINED_DATA): New define.
4333 (last_appdefined_event_data): New variable
4334 (last_appdefined_event): Remove.
4335 (ns_select): Initialize t from last_appdefined_event_data instead
4336 of [last_appdefined_event data1].
4337 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
4338 remove last_appdefined_event (Bug#12698).
4340 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
4342 * frame.c (x_set_font): Catch internal error.
4344 2012-10-27 Eli Zaretskii <eliz@gnu.org>
4346 Avoid overflow in w32 implementation of interval timers.
4347 When possible, for ITIMER_PROF count only times the main thread
4349 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
4350 'volatile ULONGLONG' types. All the other data which was
4351 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
4352 (GetThreadTimes_Proc): New typedef.
4353 (w32_get_timer_time): New function, returns a suitable time value
4355 (timer_loop): Enter critical section when accessing ULONGLONG
4356 values of the itimer_data struct, as these accesses are no longer
4357 atomic. Call 'w32_get_timer_time' instead of 'clock'.
4358 Remove unused variable.
4359 (init_timers): Initialize s_pfn_Get_Thread_Times.
4360 (start_timer_thread): Don't assign itimer->caller_thread here.
4361 (getitimer): Assign itimer->caller_thread here.
4362 (setitimer): Always call getitimer to get the value of ticks_now.
4363 (sys_spawnve): Avoid compiler warning about format mismatch.
4365 2012-10-26 Eli Zaretskii <eliz@gnu.org>
4367 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
4368 mouse movement events if the menu bar is active. This avoids
4369 producing a busy "hour-glass" cursor by Windows if the mouse
4370 pointer is positioned over a tooltip shown for some menu item.
4372 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
4374 Don't assume process IDs fit in int.
4375 * emacs.c (shut_down_emacs) [!DOS_NT]:
4376 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
4377 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
4378 Use pid_t, not int, to store process IDs, as 'int'
4379 is not wide enough on a few platforms (e.g., AIX and IRIX).
4381 2012-10-23 Kenichi Handa <handa@gnu.org>
4383 The following change is to make face-font-rescale-alist work
4384 correctly for non-ASCII fonts.
4386 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
4387 (font_open_for_lface): Handle Vface_font_rescale_alist.
4389 2012-10-23 Chong Yidong <cyd@gnu.org>
4391 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
4393 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

4402 2012-10-21 Glenn Morris <rgm@gnu.org>
4404 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
4406 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
4408 Port to OpenBSD 5.1.
4409 * frame.c (Fmouse_position, Fmouse_pixel_position):
4410 * xdisp.c (produce_stretch_glyph):
4411 Declare local vars only when they're needed.
4412 This is clearer and avoids a warning on OpenBSD about unused vars.
4413 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
4414 This is safer, and avoids OpenBSD warnings about unused vars.
4415 * keyboard.c (record_menu_key): Remove unnecessary decl.
4416 (poll_timer): Define only if POLL_FOR_INPUT is defined.
4417 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
4418 as our definition clashes with OpenBSD's.
4419 * xfaces.c (load_face_colors, check_lface_attrs)
4420 (get_lface_attributes_no_remap, get_lface_attributes)
4421 (lface_fully_specified_p, x_supports_face_attributes_p)
4422 (tty_supports_face_attributes_p, face_fontset, realize_face)
4423 (realize_x_face, realize_tty_face):
4424 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
4425 merely Lisp_Object *. This is more informative and avoids
4426 a warning on OpenBSD about accessing beyond an object's size.
4428 2012-10-20 Chong Yidong <cyd@gnu.org>
4430 * lread.c (Fload): Doc fix (Bug#12592).
4432 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
4434 * font.c (Ffont_at): Fix previous change.
4436 2012-10-19 Eli Zaretskii <eliz@gnu.org>
4438 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
4439 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html

4452 FD_ISSET (Bug#12668).
4454 2012-10-18 Daniel Colascione <dancol@dancol.org>
4456 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
4457 (staticpro): If we run out of staticpro slots, die with an
4458 informative error instead of just calling emacs_abort.
4460 2012-10-18 Martin Rudalics <rudalics@gmx.at>
4462 Fix two flaws reported by Dmitry Antipov.
4463 * window.c (Ftemp_output_buffer_show): Remove.

4484 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
4485 (sys_link): Add prototypes.

4503 * cygw32.c (Fcygwin_convert_path_to_windows)
4504 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
4505 Lisp_Object values. (Bug#12661)
4507 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
4508 to Lisp_Object. (Bug#12661)

4580 2012-10-13 Paul Eggert <eggert@cs.ucla.edu>
4582 Fix some stat-related races.
4583 * fileio.c (Fwrite_region): Avoid race condition if a file is
4584 removed or renamed by some other process immediately after Emacs
4585 writes it but before Emacs stats it. Do not assume that stat (or
4587 * image.c (slurp_file): Resolve the file name with fopen + fstat
4588 rather than stat + fopen.

4617 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
4618 instead of calling 'stat', when what's needed is to check whether
4619 a file exists. This avoids expensive system calls on MS-Windows.
4622 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
4624 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to
4625 determine whether a file exists and is not a directory.
4627 * lisp.h (check_existing): Add prototype.
4629 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
4631 * nsfont.m (nsfont_open): Remove font cache, it is not GC correct.
4633 2012-10-12 Glenn Morris <rgm@gnu.org>

4661 Use bool for booleans.
4662 * lread.c (safe_to_load_version): Rename from safe_to_load_p,
4663 as it's not a predicate. All uses changed. Omit unnecessary
4666 2012-10-11 Dmitry Antipov <dmantipov@yandex.ru>
4668 * editfns.c (save_excursion_save): Use nil if mark points to nowhere.
4669 (save_excursion_restore): Do not restore mark if it was not saved.
4671 2012-10-11 Paul Eggert <eggert@cs.ucla.edu>
4673 * marker.c (cached_modiff): EMACS_INT, not int.
4675 * w32select.c (waiting_for_input): Declare by including "keyboard.h"
4676 instead of having a wrong decl.

4714 (detect_input_pending_run_timers):
4715 * process.c (wait_reading_process_output):
4716 Use unsigned for counter where wraparound-on-overflow is desired,
4717 since unsigned is guaranteed to have that behavior and signed is not.
4718 (read_char): Use ptrdiff_t for string length.
4719 (get_input_pending): Remove first argument, since it was always
4720 the same pointer-to-int (now pointer-to-boolean) &input_pending,
4721 and behave as if it had that value. Return new value of
4722 input_pending. All callers changed.
4723 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
4724 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
4726 * keymap.c (push_key_description): Omit last arg, which was always 1.
4727 All callers changed.
4729 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
4731 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

4747 Don't include termopts.h.
4749 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
4751 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
4753 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
4755 * commands.h (immediate_quit): Remove duplicate decl.
4757 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
4759 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
4761 (nsfont_open): Remove setting of Vfonts_in_cache.
4762 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
4764 2012-10-09 Eli Zaretskii <eliz@gnu.org>
4766 * w32fns.c (w32_last_error): Change the return value to DWORD, to
4767 match what GetLastError returns. Explain why the function is
4770 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
4771 'is_tooltip_frame', to avoid confusion with its global namesake.
4773 2012-10-08 Daniel Colascione <dancol@dancol.org>
4775 * xdisp.c (start_hourglass): Call w32_note_current_window when
4776 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
4777 build that caused Emacs to display the hourglass cursor forever.
4779 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
4780 which is broken under remote desktop, calculate the number of
4781 colors available for a display based on the display's number of
4782 planes and number of bits per pixel per plane. (bug#10397).
4784 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
4786 * nsfont.m (Vfonts_in_cache): New variable.
4787 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
4788 are used. Add cached fonts to Vfonts_in_cache.
4789 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
4791 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
4793 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
4795 (FONT_H): Define after FRAME_H.
4796 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
4797 Update dependencies.
4799 * w32term.c: Remove leftover declaration of keyboard_codepage.
4801 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4803 * makefile.w32-in (FONT_H): Add $(FRAME_H).
4804 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
4805 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
4806 (GLOBAL_SOURCES): Add cygw32.c.

4809 ($(BLD)/w32console.$(O)):
4810 ($(BLD)/w32fns.$(O)):
4811 ($(BLD)/w32heap.$(O)):
4812 ($(BLD)/w32menu.$(O)):
4813 ($(BLD)/w32proc.$(O)): Add w32common.h.
4815 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
4817 (x_to_w32_color): Don't modify the argument, modify a copy instead.
4819 2012-10-08 Daniel Colascione <dancol@dancol.org>
4821 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
4822 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
4823 accidental message numbering hole. Change other messages to
4826 * w32select.h (HAVE_W32SELECT): Remove.
4828 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
4829 w32common.h instead of w32heap.h.
4831 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
4832 (get_allocation_unit, get_processor_type, get_w32_major_version)
4833 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4834 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4835 (OS_NT, os_subtype, cache_system_info): Move declarations to
4838 * w32heap.c: Include w32common.h.
4839 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
4840 (w32_minor_version, w32_build_number, w32_subtype):
4841 Remove duplicate definitions.
4843 * w32fns.c: Include w32common.h; include w32heap.h only in
4846 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
4847 Use `report_file_error' instead of `error' in order to better
4848 inform users of what went wrong. Increase NTGUI_UNICODE file
4849 dialog box file name length to 32k, the maximum allowed by the NT
4852 * w32common.h: New file.
4853 (ROUND_UP, ROUND_DOWN, get_page_size)
4854 (get_allocation_unit, get_processor_type, get_w32_major_version)
4855 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4856 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4857 (OS_NT, os_subtype, cache_system_info): Move here.
4859 * unexw32.c, unexcw.c: Include w32common.h.
4861 * emacs.c (main): Use (defined (WINDOWSNT) || defined
4862 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
4863 to call syms_of_w32select.
4865 * cygw32.h: Remove obsolete EXFUN declarations.
4867 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
4869 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
4870 of w32inevt.o from SOME_MACHINE_OBJECTS.
4872 2012-10-08 Daniel Colascione <dancol@dancol.org>
4874 * image.c: Permanent fix for JPEG compilation issue --- limit
4875 jpeglib `boolean' redefinition to Cygwin builds.
4877 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4879 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
4881 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
4884 2012-10-08 Daniel Colascione <dancol@dancol.org>
4886 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4887 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
4888 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
4889 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
4890 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
4891 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4892 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4893 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4894 now a supported configuration.
4896 * Makefile.in: consolidate image variables into LIBIMAGE; add
4897 W32_OBJ and W32_LIBS. Compile new files.
4900 (_DebPrint) declare tracing facility for W32 debugging. We need
4901 to unify tracing later.
4903 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4904 unconditional use of W32 Unicode functions. Cygwin runs only on
4905 100% Unicode operating systems.
4907 * cygw32.c: New file. Define Cygwin-specific facilities.
4908 (Fcygwin_convert_path_to_windows)
4909 (Fcygwin_convert_path_from_windows): New user functions for
4910 accessing Cygwin path-munging routines.
4912 * cygw32.h: New file.
4913 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4914 UTF-16LE strings temporarily inside non-Lisp-visible string
4917 (w32_strerror): Just what it says on the tin.
4919 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4920 also run for Cygwin; both systems have the same problem with using
4921 GUI facilities in a forked child. Also call syms_of_cygw32,
4922 syms_of_w32select in correct places.
4924 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4925 needs fork-then-exec for daemon launching.
4927 * font.h: Include frame.h.
4929 * image.c: Use the image library cache machinery only when we're
4930 compiling for native WINDOWSNT; Cygwin can use shared libraries
4931 like any other Unixlike system.
4933 * keyboard.c: Clarify a comment regarding the input loop.
4935 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4936 functions directly instead of trying to detect at runtime that our
4937 host operating system supports them. We make this change for two
4938 reasons: Cygwin lacks support for the multibyte character
4939 conversion functions used by the legacy menu code, and Cygwin
4940 never needs to rely on non-Unicode APIs.
4942 * unexw32.c (hinst): Declare extern.
4944 * w32.c: Change header order;
4945 (w32_strerror): Move to w32fns.c because we need it for
4946 non-WINDOWSNT builds.
4948 * w32.h: Add #error macro to make sure we don't include w32.h for
4949 Cygwin builds. Remove w32select declarations.
4951 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4952 w32fns.c. w32console.c is WINDOWSNT-only.
4954 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4955 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4957 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4958 (w32_major_version, w32_minor_version, w32_build_number)
4959 (os_subtype, sound_type): Define here
4960 (w32_defined_color): Make color parameter const for consistency
4961 with other _defined_color functions.
4962 (w32_createwindow): Unconditionally call w32_init_class instead of
4963 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4964 through the code is complex and unnecessary because class
4965 registration is practically free.
4966 (w32_name_of_message): New EMACSDEBUG-only function.
4967 (Fset_message_beep): Move here
4968 (Fx_open_connection): Require that the display name for Windows be
4969 "w32" for consistency, emacsclient disambiguation, and maybe, one
4970 day, multi-window-system support.
4971 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4972 Cygwin files for W32 GUI facilities, since these clearly don't
4973 expect Cygwin names.
4974 (_DebPrint): Define.
4975 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4976 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4977 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4978 (w32_last_error): Remove.
4980 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4982 * w32heap.c (syspage_mask): Declare here.
4983 (cache_system_info): Remove.
4985 * w32inevt.c (faked_key): Define globally, not statically.
4986 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4987 (w32_console_toggle_lock_key): Move to w32fns.c.
4989 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4991 * w32proc.c (_DebPrint): Move to w32fns.c.
4992 * w32select.c: Include string.h, stdio.h for Cygwin.
4993 * w32select.h: New File.
4995 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4997 (w32_message_fd): New variable. Under Cygwin, holds the file
4998 descriptor the system used to tell us about pending thread
5001 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
5002 that prevented compilation under non-WINDOWSNT systems.
5004 (w32_initialize): Open /dev/windows and assign it to
5005 w32_message_fd. Provide w32 feature.
5007 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
5008 (WM_EMACS_INPUT_READY): add.
5009 (prepend_msg, w32_message_fd): Declare globally.
5012 (keyboard_handle): Use only when WINDOWSNT.
5013 (notify_msg_ready): New function. Posts a message to the main
5014 thread's message queue under CYGWIN, which wakes up the main
5015 thread from select(2) by making the /dev/windows file descriptor
5016 ready. Under WINDOWSNT, it sets an event the same way the old
5019 (post, prepend_msg): Actually call notify_msg_ready instead of
5020 setting the input event directly.
5022 2012-10-07 Eli Zaretskii <eliz@gnu.org>
5024 * ralloc.c (relinquish): If a heap is ready to be relinquished,
5025 but it still has blocs in it, don't return it to the system,
5026 instead of aborting. (Bug#12402)
5028 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
5030 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
5032 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
5033 MAC_OS_X_VERSION_10_6.
5034 (syms_of_nsterm): Remove comment about Panther and above for
5036 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
5037 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
5038 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
5040 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
5041 MAC_OS_X_VERSION_10_4.
5043 * nsmenu.m (fillWithWidgetValue:): Remove code for <
5044 MAC_OS_X_VERSION_10_2.
5046 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
5048 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
5049 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
5051 * nsterm.m (ns_in_resize): Remove (Bug#12479).
5052 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
5053 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
5054 Remove ns_in_resize check.
5055 (ns_clear_frame_area): Remove resize handle code.
5057 * nsfns.m (ns_in_resize): Remove.
5058 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
5059 Remove ns_in_resize check.
5061 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
5063 Improve sys_siglist detection.
5064 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
5065 defined as a macro, as is done in Solaris.
5066 (sys_siglist_entries): New macro.
5067 (save_strsignal): Use it.
5068 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
5069 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
5071 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
5073 * nsfns.m (Fx_create_frame): Call x_default_parameter with
5074 fullscreen/Fullscreen.
5076 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
5077 tobar_height is new.
5079 * nsterm.m (x_make_frame_visible): Check for fullscreen.
5080 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
5081 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
5082 (windowDidResize:): Check for correct window if old style fullscreen.

5084 (initFrameFromEmacs:): tbar_height renamed tibar_height.
5085 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
5086 error in drawing background.
5087 (toggleFullScreen:): Remove comment. Rearrange calls.

5094 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
5096 2012-10-05 Eli Zaretskii <eliz@gnu.org>
5098 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
5100 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
5101 that time stamps of directories could also be changed.
5102 Don't request the too broad GENERIC_WRITE, only the more restrictive
5103 FILE_WRITE_ATTRIBUTES access rights.
5105 * fileio.c (Fset_file_times): Special-case ignoring errors for
5106 directories only on MSDOS, not on MS-Windows.
5108 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
5110 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
5112 2012-10-04 Eli Zaretskii <eliz@gnu.org>
5114 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
5115 see whether CreateFile failed.
5117 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
5119 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
5120 to avoid similar races.
5121 * keyboard.c (pending_signals): Now bool, not int.
5123 Port timers to OpenBSD, plus check for timer failures.
5124 OpenBSD problem reported by Han Boetes.
5125 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
5127 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
5128 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
5129 like OpenBSD, which has timer_settime but does not declare it.
5130 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
5131 whether to use itimerspec-related primitives. All uses of
5132 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
5134 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5136 * profiler.c (handle_profiler_signal): Fix a malloc race
5137 that caused Emacs to hang on Fedora 17 when profiling Lisp.
5139 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
5141 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
5143 2012-10-02 Eli Zaretskii <eliz@gnu.org>
5145 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
5146 consistent with the change in return value of 'safe_strsignal'.
5148 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5150 Prefer plain 'static' to 'static inline' (Bug#12541).
5151 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
5152 (bidi_set_sor_type, bidi_push_embedding_level)
5153 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

5158 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5159 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
5160 Now 'static', not 'static inline'.
5162 Count overruns when profiling; change units to ns.
5163 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
5164 Give extra weight to samples after overruns, to attempt to count
5165 the time more accurately.
5166 (setup_cpu_timer): Change sampling interval units from ms to ns, since
5167 the underlying primitives nominally do ns.
5168 (Fprofiler_cpu_start): Document the change. Mention that
5169 the sampling intervals are only approximate.
5171 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5173 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
5175 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
5176 case for the special 0 coding-system.
5178 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
5179 (Fmake_overlay): Remove redundant tests.
5180 (fix_start_end_in_overlays): Remove redundant recentering.
5182 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
5184 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
5185 Update dependencies.
5187 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5189 Fix a malloc race condition involving strsignal.
5190 A signal can arrive in the middle of a malloc, and Emacs's signal
5191 handler can invoke strsignal, which can invoke malloc, which is
5192 not portable. This race condition bug makes Emacs hang on GNU/Linux.
5193 Fix it by altering the signal handler so that it does not invoke
5195 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
5196 * process.c (status_message): Use const pointer, in case strsignal
5197 is #defined to safe_strsignal.
5198 * sysdep.c (sys_siglist, init_signals): Always define and
5199 initialize a substitute sys_siglist if the system does not define
5200 one, even if HAVE_STRSIGNAL.
5201 (safe_strsignal): Rename from strsignal. Always define,
5202 using sys_siglist. Return a const pointer.
5203 * syssignal.h (safe_strsignal): New decl.
5204 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
5206 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5208 * w32proc.c (timer_loop): Fix code that waits for timer
5209 expiration, to avoid high CPU usage.
5211 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
5213 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
5214 (sweep_weak_table): Remove redundant prototypes.
5216 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
5218 * emacs.c: Move the inclusion of TERM_HEADER after including
5219 windows.h on WINDOWSNT. This avoids compilation problems with
5222 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5224 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
5225 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
5226 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
5227 as the previous version used 'void *'.
5229 * ralloc.c (ROUNDUP): Fix last change.
5230 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
5233 * w32proc.c <disable_itimers>: New static flag.
5234 (init_timers): Initialize it to zero, after creating the critical
5235 sections used by the timer threads.
5236 (term_timers): Set to 1 before deleting the critical sections.
5237 (getitimer, setitimer): If disable_itimers is non-zero, return an
5238 error indication without doing anything. Reported by Fabrice
5239 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
5240 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
5242 [!HAVE_SETITIMER]: Behave as the previous version that didn't
5245 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
5246 term_ntproc after all the other bookkeeping, to get timers working
5247 as long as possible.
5249 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5251 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
5252 Suggested by Juri Linkov in
5253 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
5255 Prefer plain 'static' to 'static inline' (Bug#12541).
5256 With static functions, modern compilers inline pretty well by
5257 themselves; advice from programmers often hurts as much as it helps.
5258 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
5259 this change shrinks the text size of the Emacs executable by 1.1%
5260 without affecting CPU significantly in my benchmark.
5261 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

5343 Revert the FOLLOW-SYMLINKS change for file-attributes.
5344 Doing it right would require several changes to Tramp, and there's
5345 not enough time to get that tested before the freeze today.
5346 * dired.c (directory_files_internal, Ffile_attributes):
5349 * frame.c (x_report_frame_params): Port better to wider ints.
5350 Do not assume that EMACS_UINT is the same width as uprintmax_t,
5351 or that pointers can be printed in 15 decimal digits.
5352 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

5470 * xdisp.c (start_hourglass, cancel_hourglass): Now used on
5472 (start_hourglass) [WINDOWSNT]: Call w32_note_current_window.
5474 * w32.h (init_timers, term_timers): Add prototypes.
5476 2012-09-30 Kenichi Handa <handa@gnu.org>
5478 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
5479 to the buffer relocation which may be caused by ccl_driver.

5528 (Qwindow_size): New symbol replacing Qtemp_buffer_resize.
5530 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
5532 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
5533 Suggested by Eli Zaretskii in
5534 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
5536 2012-09-30 Eli Zaretskii <eliz@gnu.org>
5538 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
5539 HAVE_TIMER_SETTIME is defined.
5541 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
5543 Profiler improvements: more-accurate timers, overflow checks.
5544 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
5545 signal.h, setjmp.h. Include systime.h instead.
5546 (saturated_add): New function.
5547 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
5548 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
5549 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
5551 (enum profiler_cpu_running): New enum.
5552 (profiler_cpu_running): Now of that enum type, not bool.
5553 All uses changed to store the new value.
5554 (handle_profiler_signal): Rename from sigprof_handler_1,
5555 for consistency with other handlers. Do not check whether
5556 cpu_log is a hash-table if garbage collecting, since it
5557 doesn't matter in that case.
5558 (deliver_profiler_signal): Rename from sigprof_handler,
5559 for consistency with other handlers.
5560 (setup_cpu_timer): New function, with much of what used to be in
5561 Fprofiler_cpu_start. Check for out-of-range argument.
5562 Prefer timer_settime if available, and prefer
5563 thread cputime clocks, then process cputime clocks, then
5564 monotonic clocks, to the old realtime clock. Use make_timeval
5565 to round more-correctly when falling back to setitimer.
5566 (Fprofiler_cpu_start): Use it.
5567 (Fprofiler_cpu_stop): Prefer timer_settime if available.
5568 Don't assume that passing NULL as the 2nd argument of setitimer
5569 is the same as passing a pointer to all-zero storage.
5570 Ignore SIGPROF afterwards.
5571 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
5572 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
5573 non-fatal signal handlers. Ignore SIGPROF on startup.
5574 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
5575 in profiler.c, since sysdep.c now uses it.
5577 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
5578 Suggested by Eli Zaretskii in

5592 (Fbacktrace_frame): Adjust accordingly.
5594 2012-09-28 Glenn Morris <rgm@gnu.org>
5596 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
5597 (Frun_hook_with_args_until_failure): Doc fixes.
5599 2012-09-28 Eli Zaretskii <eliz@gnu.org>
5601 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
5602 Qautomatic_redisplay and change the symbol name. All users changed.
5604 2012-09-28 Tomohiro Matsuyama <tomo@cx4a.org>

5631 * character.h (MAYBE_UNIFY_CHAR): Remove.
5632 * charset.c, charset.h (maybe_unify_char): Now static.
5633 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
5634 Since this stuff is now private to charset.c, there's no need for
5635 a public macro and no need to inline by hand.

5668 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
5670 Prefer POSIX timers if available.
5671 They avoid a race if the timer is too close to the current time.
5672 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
5673 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
5674 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
5676 2012-09-25 Eli Zaretskii <eliz@gnu.org>
5678 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
5679 CHAR_STRING_ADVANCE.
5680 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
5681 STRING_CHAR_ADVANCE.

5690 * image.c (reset_image_types): New function.
5692 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

5697 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
5699 * w32.h (Vlibrary_cache): Do not declare.
5701 2012-09-25 Eli Zaretskii <eliz@gnu.org>
5703 * w32proc.c (sys_signal): Handle all signals defined by the
5704 MS-Windows runtime, not just SIGCHLD. Actually install the signal
5705 handlers for signals supported by Windows. Don't override
5706 term_ntproc as the handler for SIGABRT.
5707 (sigaction): Rewrite to call sys_signal instead of duplicating its
5709 (sys_kill): Improve commentary.
5711 * w32.c (term_ntproc): Accept (and ignore) one argument, for
5712 consistency with a signature of a signal handler. All callers
5714 (init_ntproc): Accept an argument DUMPING. If dumping, don't
5715 install term_ntproc as a signal handler for SIGABRT, as that
5716 should be done by the dumped Emacs.
5718 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
5720 * w32select.c (term_w32select): Protect against repeated
5721 invocation by setting clipboard_owner to NULL after calling
5724 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
5725 and term_ntproc to their modified signatures.
5727 * character.c (char_string, string_char): Remove calls to
5728 MAYBE_UNIFY_CHAR. See the discussion starting at
5729 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
5732 2012-09-25 Chong Yidong <cyd@gnu.org>

5736 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
5738 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
5739 when encountering an unknown bytecode.
5741 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
5743 image.c, indent.c: Use bool for booleans.
5744 * dispextern.h (struct image_type): Members valid_p, load, init
5745 now return bool, not int. All uses changed.
5746 * image.c: Omit unnecessary static decls.
5747 (x_create_bitmap_mask, x_build_heuristic_mask):

5785 Move pid_t related decls out of lisp.h.
5786 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
5787 (interruptible_wait_for_termination):
5788 Move these decls from lisp.h to syswait.h, since they use pid_t.
5789 Needed on FreeBSD; see Herbert J. Skuhra in
5790 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.

5837 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5839 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5840 fatal_error_backtrace.
5842 * w32proc.c (sys_kill): Undo last change: don't do anything when
5843 invoked to deliver SIGABRT to our own process. This is now
5844 handled by emacs_raise.
5846 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5848 * w32term.c (w32_read_socket): Remove leftover reference to
5849 interrupt_input_pending.
5851 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5853 Do not use SA_NODEFER.
5854 Problem reported by Dani Moncayo in
5855 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5857 * sysdep.c (emacs_abort): Do not reset signal handler.
5858 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5859 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5860 wanted even on POSIXish hosts, and it doesn't work on Windows.
5862 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5864 * xterm.c (x_term_init): Call fixup_locale before and after calling
5865 gtk_init (Bug#12392).
5867 2012-09-23 Chong Yidong <cyd@gnu.org>
5869 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5870 Vdynamic_library_alist.
5872 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5873 (Fgnutls_available_p): Caller changed.
5875 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5876 (Flibxml_parse_xml_region): Likewise.
5878 * dispextern.h (struct image_type): Remove arg from init function.
5880 * image.c (Finit_image_library, lookup_image_type)
5881 (define_image_type): Remove now-unneeded second arg.
5882 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5883 (init_tiff_functions, init_gif_functions, init_svg_functions):
5884 Arglist and w32_delayed_load calling convention changed.
5885 (gs_type): Remove init_gs_functions; there is no such function.
5886 (valid_image_p, make_image): Fix caller to lookup_image_type.
5888 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5890 Simplify and avoid signal-handling races (Bug#12471).
5892 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5893 Avoid recursive loop if there's a fatal error in the function itself.
5894 * atimer.c (pending_atimers):
5895 * blockinput.h: Don't include "atimer.h"; no longer needed.
5896 (interrupt_input_pending): Remove. All uses removed.
5897 pending_signals now counts both atimers and ordinary interrupts.
5898 This is less racy than having three separate pending-signal flags.
5899 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5901 Rename from their upper-case counterparts BLOCK_INPUT,
5902 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5903 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5904 This makes it easier to access volatile variables more accurately.
5905 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5906 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5907 that's more reliable if the code is buggy and sets
5908 interrupt_input_blocked to a negative value. All uses changed.
5909 * atimer.c (deliver_alarm_signal):
5910 Remove. No need to deliver this to the parent; any thread can
5911 handle this signal now. All uses replaced by underlying handler.
5912 * atimer.c (turn_on_atimers):
5913 * dispnew.c (handle_window_change_signal):
5914 * emacs.c (handle_danger_signal):
5915 * keyboard.c (kbd_buffer_get_event):
5916 Don't reestablish signal handler; not needed with sigaction.
5917 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5919 Rework to avoid unnecessary accesses to volatile variables.
5920 (UNBLOCK_INPUT_TO): Now a function.
5921 (totally_unblock_input, unblock_input): New decls.
5922 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5923 (init_data): Remove. Necessary stuff now done in init_signal.
5924 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5925 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5926 (fatal_error_code): Remove; no longer needed.
5927 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5928 it doesn't always backtrace. All uses changed. No need to reset
5929 signal to default, since sigaction and/or die does that for us now.
5930 Use emacs_raise (FOO), not kill (getpid (), FOO).
5931 (main): Check more-accurately whether we're dumping.
5932 Move fatal-error setup to sysdep.c
5933 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5934 * gtkutil.c (xg_get_file_name, xg_get_font):
5935 Remove no-longer-needed signal-mask manipulation.
5936 * keyboard.c, process.c (POLL_FOR_INPUT):
5937 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5938 * keyboard.c (read_avail_input): Remove.
5939 All uses replaced by gobble_input.
5940 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5941 (kbd_buffer_store_event_hold, gobble_input):
5942 (record_asynch_buffer_change) [USABLE_SIGIO]:
5943 (store_user_signal_events):
5944 No need to mess with signal mask.
5945 (gobble_input): If blocking input and there are terminals, simply
5946 set pending_signals to 1 and return. All hooks changed to not
5947 worry about whether input is blocked.
5948 (process_pending_signals): Clear pending_signals before processing
5949 them, in case a signal comes in while we're processing.
5950 By convention callers now test pending_signals before calling us.
5951 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5952 New functions, to support changes to blockinput.h.
5953 (handle_input_available_signal): Now extern.
5954 (reinvoke_input_signal): Remove. All uses replaced by
5956 (quit_count): Now volatile, since a signal handler uses it.
5957 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5958 All callers changed. Block SIGINT only if not already blocked.
5959 Clear sigmask reliably, even if Fsignal returns, which it can.
5960 Omit unnecessary accesses to volatile var.
5961 (quit_throw_to_read_char): No need to restore sigmask.
5962 * keyboard.c (gobble_input, handle_user_signal):
5963 * process.c (wait_reading_process_output):
5964 Call signal-handling code rather than killing ourselves.
5965 * lisp.h: Include <float.h>, for...
5966 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5967 (pending_signals): Now volatile.
5968 (syms_of_data): Now const if IEEE floating point.
5969 (handle_input_available_signal) [USABLE_SIGIO]:
5970 (terminate_due_to_signal, record_child_status_change): New decls.
5971 * process.c (create_process): Avoid disaster if memory is exhausted
5972 while we're processing a vfork, by tightening the critical section
5974 (send_process_frame, process_sent_to, handle_pipe_signal)
5975 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5977 (send_process): No need for setjmp/longjmp any more, since the
5978 SIGPIPE stuff is now gone. Instead, report an error if errno
5980 (record_child_status_change): Now extern. PID and W are now args.
5981 Return void, not bool. All callers changed.
5982 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5983 Remove. All uses removed. This bug should be fixed now in a
5985 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5986 and record the child status change directly. This avoids the
5987 need to futz with the signal mask.
5988 (process_fatal_action): Move here from emacs.c.
5989 (emacs_sigaction_flags): New function, containing
5990 much of what used to be in emacs_sigaction_init.
5991 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5992 caught by emacs, to make races less likely.
5993 (deliver_process_signal): Rename from handle_on_main_thread.
5995 (BACKTRACE_LIMIT_MAX): Now at top level.
5996 (thread_backtrace_buffer, threadback_backtrace_pointers):
5998 (deliver_thread_signal, deliver_fatal_thread_signal):
5999 New functions, for more-accurate delivery of thread-specific signals.
6000 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
6001 (deliver_arith_signal): Handle in this thread, not
6002 in the main thread, since it's triggered by this thread.
6003 (maybe_fatal_sig): New function.
6004 (init_signals): New arg DUMPING so that we can be more accurate
6005 about whether we're dumping. Caller changed.
6006 Treat thread-specific signals differently from process-general signals.
6007 Block all signals while handling fatal error; that's safer.
6008 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
6010 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
6011 Ignore SIGPIPE unless batch.
6012 (emacs_backtrace): Output backtrace for the appropriate thread,
6013 which is not necessarily the main thread.
6014 * syssignal.h: Include <stdbool.h>.
6015 (emacs_raise): New macro.
6016 * xterm.c (x_connection_signal): Remove; no longer needed
6017 now that we use sigaction.
6018 (x_connection_closed): No need to mess with sigmask now.
6019 (x_initialize): No need to reset SIGPIPE handler here, since
6020 init_signals does this for us now.
6022 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6024 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
6025 background rect may be larger (Bug#12245).
6027 2012-09-23 Chong Yidong <cyd@gnu.org>
6029 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
6031 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6033 * .gdbinit: Just stop at fatal_error_backtrace.
6034 See Stefan Monnier's request in
6035 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
6036 Remove no-longer-used query of system type.
6038 2012-09-22 Chong Yidong <cyd@gnu.org>
6040 * search.c (Freplace_match): Doc fix (Bug#12325).
6042 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
6044 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
6045 (Fline_end_position): Doc fix.
6047 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
6049 2012-09-22 Chong Yidong <cyd@gnu.org>
6051 * dispextern.h (struct image_type): Add new slot, storing a type
6052 initialization function.
6054 * image.c (define_image_type): Call the image initializer function
6055 if it is defined. Arguments and return value changed.
6056 (valid_image_p, make_image): Callers changed.
6057 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
6058 (gif_type, imagemagick_type, svg_type, gs_type):
6059 Add initialization functions.
6060 (Finit_image_library): Call lookup_image_type.
6061 (CHECK_LIB_AVAILABLE): Macro deleted.
6062 (lookup_image_type): Call define_image_type here, rather than via
6063 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
6064 (syms_of_image): Move define_image_type calls for xbm_type and
6065 pbm_type to lookup_image_type.
6067 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6069 * keyboard.c (timer_check_2): Move calculation of 'timers' and
6070 'idle_timers' from here ...
6071 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
6072 lists, to avoid infloops when the timer does something stupid,
6073 like reinvoke itself with the same or smaller time-out.
6076 2012-09-22 Martin Rudalics <rudalics@gmx.at>
6078 * window.c (Fsplit_window_internal): Handle only Qt value of
6079 Vwindow_combination_limit separately.
6080 (Qtemp_buffer_resize): New symbol.
6081 (Vwindow_combination_limit): New default value.
6084 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6086 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
6087 the new overlay string. (Bug#10159)
6089 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6091 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
6092 or that fprintf is async-signal-safe. POSIX doesn't require
6095 2012-09-22 Chong Yidong <cyd@gnu.org>
6097 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
6100 2012-09-22 Kenichi Handa <handa@gnu.org>
6102 * composite.c (composition_reseat_it): Handle the case that a
6103 grapheme cluster is not covered by a single font (Bug#12352).
6105 2012-09-21 Chong Yidong <cyd@gnu.org>
6107 * image.c (define_image_type): Avoid adding duplicate types to
6108 image_types (Bug#12463). Suggested by Jörg Walter.
6110 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6112 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
6113 (print_load_command_name): Add case LC_DATA_IN_CODE.
6114 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
6116 2012-09-21 Glenn Morris <rgm@gnu.org>
6118 * eval.c (Frun_hook_with_args_until_success)
6119 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
6121 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
6123 * fileio.c (Ffile_selinux_context): Only call freecon when
6124 lgetfilecon succeeded.
6125 (Fset_file_selinux_context): Likewise. (Bug#12444)
6127 2012-09-21 Eli Zaretskii <eliz@gnu.org>
6129 * xdisp.c (try_window_reusing_current_matrix): Under bidi
6130 reordering, locate the cursor by calling set_cursor_from_row; if
6131 that fails, clear the desired glyph matrix before returning a
6132 failure indication to the caller. Fixes leaving garbled display
6133 when fast scrolling with a down-key. (Bug#12403)
6134 (compute_stop_pos_backwards): Fix a typo that caused crashes while
6135 scrolling through multibyte text.
6137 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
6139 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
6140 calling mark_vectorlike since that's the one that marks the window.
6141 (mark_discard_killed_buffers): Mark the final cdr.
6142 * window.h (struct window): Move prev/next_buffers to the
6143 non-standard fields.
6144 * window.c (make_window): Initialize prev/next_buffers manually.
6146 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
6148 Omit unused arg EXPECTED from socket hooks.
6149 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
6150 * nsterm.m (ns_term_init):
6151 * termhooks.h (struct terminal.read_socket_hook):
6152 * w32inevt.c (w32_console_read_socket):
6153 * w32term.c (w32_read_socket):
6154 * xterm.c (XTread_socket):
6155 Omit unused arg EXPECTED. All callers changed.
6156 (store_user_signal_events): Return void, not int, since callers no
6157 longer care about the return value. All uses changed.
6159 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
6161 * w32gui.h (XParseGeometry): Do not declare.
6163 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
6165 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
6166 Ignore 'expected'. See Eli Zaretskii in
6167 <http://bugs.gnu.org/12471#8> (last line).
6169 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
6170 (XParseGeometry): Now static. Substitute extremal values for
6171 values that are out of range.
6173 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
6175 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
6177 * nsfns.m (XParseGeometry): Remove.
6178 (Fx_create_frame): Call x_set_offset to correctly interpret
6179 top_pos in geometry.
6181 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
6182 (Fx_parse_geometry): If there is a space in string, call
6183 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
6185 2012-09-17 Eli Zaretskii <eliz@gnu.org>
6187 * search.c (scan_buffer): Use character positions in calls to
6188 region_cache_forward and region_cache_backward, not byte
6189 positions. (Bug#12196)
6191 * w32term.c (w32_read_socket): Set pending_signals to 1, like
6192 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
6194 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
6195 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
6196 emacs_blocked_malloc, now deleted.
6198 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
6200 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
6201 The workaround was for improving performance on Solaris 2.4, but
6202 is getting in the way now. Emacs will still work if someone is
6203 still running Solaris 2.4 in a museum somewhere; Sun dropped
6204 support for Solaris 2.4 in 2003.
6205 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
6206 * process.c (create_process) [HAVE_WORKING_VFORK]:
6207 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
6208 since Emacs no longer uses vfork on that platform.
6210 2012-09-17 Glenn Morris <rgm@gnu.org>
6212 * emacs.c: Use COPYRIGHT.
6214 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
6216 Remove configure's --without-sync-input option (Bug#12450).
6217 When auditing signal-handling in preparation for cleaning it up,
6218 I found that SYNC_INPUT has race conditions and would be a real
6219 pain to fix. Since it's an undocumented and deprecated
6220 configure-time option, now seems like a good time to remove it.
6221 Also see <http://bugs.gnu.org/11080#16>.
6222 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
6223 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
6224 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6225 (malloc_hysteresis):
6226 (check_depth) [XMALLOC_OVERRUN_CHECK]:
6227 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
6228 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
6229 (dont_register_blocks, bytes_used_when_reconsidered)
6230 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
6231 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
6232 [!SYSTEM_MALLOC && !SYNC_INPUT]:
6233 Remove. All uses removed.
6234 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
6235 implementation, one that depends on whether the new macro
6236 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
6238 * atimer.c (run_timers, handle_alarm_signal):
6239 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
6240 (handle_async_input, process_pending_signals)
6241 (handle_input_available_signal, init_keyboard):
6242 * nsterm.m (ns_read_socket):
6243 * process.c (wait_reading_process_output):
6244 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
6245 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
6247 * xterm.c (XTread_socket):
6249 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
6250 * eval.c (handling_signal): Remove. All uses removed.
6251 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
6252 All uses replaced with the SYNC_INPUT version.
6253 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
6255 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6258 * font.c (Ffont_shape_gstring): Remove unused local.
6260 2012-09-16 Glenn Morris <rgm@gnu.org>
6262 * Makefile.in (clean): No longer run nextstep's clean.
6264 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
6266 (ns-app): Move here from ns.mk, and simplify.
6267 (clean): Simplify nextstep entry.
6268 * ns.mk: Remove file.
6270 2012-09-17 Kenichi Handa <handa@gnu.org>
6272 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
6273 not covert the last few charactes.
6275 2012-09-16 Kenichi Handa <handa@gnu.org>
6277 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
6278 here, but just check the validity of glyphs in the glyph-string.
6280 2012-09-16 Martin Rudalics <rudalics@gmx.at>
6282 * window.c (Fwindow_parameter, Fset_window_parameter):
6283 Accept any window as argument (Bug#12452).
6285 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
6287 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
6288 to ns_term_init to avoid memory leak.
6290 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
6291 explicit retain/release.
6292 (ns_term_init): Only allow one display. Initialize outerpool and
6295 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6297 Port _setjmp fix to POSIXish hosts as well as Microsoft.
6298 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
6299 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
6300 the Microsoft problem in a different way, by altering ../nt/config.nt.
6302 2012-09-15 Eli Zaretskii <eliz@gnu.org>
6317 * w16select.c: Remove inclusion of setjmp.h, as it is now included
6318 by lisp.h. This completes removal of setjmp.h inclusion
6319 erroneously announced in the previous commit. (Bug#12446)
6321 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
6324 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
6325 not defined as a macro. The latter happens on MS-Windows.
6328 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6330 Port better to POSIX hosts lacking _setjmp (Bug#12446).
6331 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
6332 Some instances of '#include <setjmp.h>' removed, if the
6333 only reason for the instance was because "lisp.h" was included.
6334 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
6335 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
6336 and _longjmp with the new symbols. Emacs already uses _setjmp if
6337 available, so this change affects only POSIXish hosts that have
6338 sigsetjmp but not _setjmp, such as some versions of Solaris and
6339 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
6340 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
6341 (png_load_body) [HAVE_PNG]:
6342 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
6343 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
6344 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
6345 since PNG requires jmp_buf. This is the only exception to the
6346 general rule that we now use sys_setjmp and sys_longjmp.
6347 This exception is OK since this code does not change the signal
6348 mask or longjmp out of a signal handler.
6350 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
6352 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6353 Include "syssignal.h", for 'main_thread'.
6355 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
6357 Avoid out-of-range marker position (Bug#12426).
6358 * insdel.c (replace_range, replace_range_2):
6359 Adjust markers before overlays, as suggested by comments.
6360 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
6361 Remove redundant check before calling offset_intervals.
6363 2012-09-14 Martin Rudalics <rudalics@gmx.at>
6365 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
6366 current buffer (Bug#12387).
6368 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
6370 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
6372 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6374 Use a more backwards-compatible timer format (Bug#12430).
6375 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
6376 vector element, not from the 4th, since PSECS is now at the end.
6377 (Fcurrent_idle_time): Doc fix.
6379 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
6381 Function to mark objects and remove killed buffers at once.
6382 * alloc.c (discard_killed_buffers): Rename to ...
6383 (mark_discard_killed buffers) ... new name. Add marking
6384 of remaining objects. Fix comment. Adjust users.
6385 (mark_object): Do not touch frame buffer lists here.
6386 * frame.c (delete_frame): Reset frame buffer lists here.
6388 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6390 Better workaround for GNOME bug when --enable-gcc-warnings.
6391 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
6392 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
6393 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
6395 Simplify SIGIO usage (Bug#12408).
6396 The code that dealt with SIGIO was crufty and confusing, e.g., it
6397 played tricks like "#undef SIGIO" but these tricks were not used
6398 consistently. Simplify mostly by not #undeffing standard symbols,
6399 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
6400 or not as we please) rather than "defined SIGIO" (standard symbol
6401 that we probably shouldn't #undef).
6402 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
6403 Modules that need it can include it.
6404 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
6405 * dispextern.h (ignore_sigio): New decl.
6406 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
6407 unconditionally, since it's now a no-op if !USABLE_SIGIO.
6408 * emacs.c (shut_down_emacs):
6409 * keyboard.c (kbd_buffer_store_event_hold):
6410 Use ignore_sigio rather than invoking 'signal' directly.
6411 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
6413 (FIONREAD, SIGIO): Do not #undef.
6414 (tty_read_avail_input): Use #error rather than a syntax error.
6415 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
6416 for I_PIPE, used by SETUP_SLAVE_PTY.
6417 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
6418 * sysdep.c (croak): Remove; no longer needed. This bit of
6419 temporary code, with Fred N. Fish's comment that it's temporary,
6420 has been in Emacs since at least 1992!
6421 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
6422 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
6423 * syssignal.h (croak): Remove decl.
6424 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
6425 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
6426 now that we're termios-only.
6427 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
6428 * term.c (dissociate_if_controlling_tty): Use #error rather than
6431 Work around GCC and GNOME bugs when --enable-gcc-warnings.
6432 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
6433 to work around GNOME bug 683906.
6434 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
6435 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
6436 This works around GCC bug 54561.
6438 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6440 More fixes for 'volatile' and setjmp/longjmp.
6441 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
6442 * image.c (struct png_load_context) [HAVE_PNG]: New type.
6443 (png_load_body) [HAVE_PNG]:
6444 (jpeg_load_body) [HAVE_JPEG]:
6445 New function, with most of the old parent function's body.
6446 (png_load) [HAVE_PNG]:
6447 (jpeg_load) [HAVE_JPEG]:
6448 Invoke the new function, to avoid longjmp munging our locals.
6449 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
6450 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
6451 longjmp is passed 2, as the C standard doesn't guarantee this.
6452 Instead, store the failure code into mgr->failure_code.
6454 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6456 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
6457 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
6458 (syms_of_keyboard): Remove support for unread-command-char.
6460 2012-09-12 Eli Zaretskii <eliz@gnu.org>
6462 * w32proc.c (sys_kill): If PID is our process ID and the signal is
6463 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
6464 violation. (Bug#12426)
6466 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6468 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
6470 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6472 * eval.c: Add `inhibit-debugger'.
6473 (Qinhibit_debugger): New symbol.
6474 (call_debugger): Bind it instead of Qdebug_on_error.
6475 (maybe_call_debugger): Test Vinhibit_debugger.
6476 (syms_of_eval): Define inhibit-debugger.
6477 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6478 (syms_of_xdisp): Remove inhibit-debug-on-message.
6480 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6482 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6483 If a nonvolatile local variable is written before a _longjmp to
6484 the frame containing the variable, and is read after the _longjmp,
6485 the value read is indeterminate. Some local variables of type
6486 'struct handler' and 'struct catchtag' are used in this way, so
6487 mark each of their slots as volatile if the slot can be set before
6488 _longjmp and read afterwards.
6489 * lisp.h (struct handler): var and chosen_clause are now volatile.
6490 (struct catchtag): val, next, and pdlcount are now volatile.
6492 * bidi.c (bidi_push_it, bidi_pop_it):
6493 * fns.c (copy_hash_table):
6494 * image.c (define_image_type):
6495 * keyboard.c (kbd_buffer_store_event_hold):
6496 * process.c (Fprocess_send_eof):
6497 * xfaces.c (x_create_gc) [HAVE_NS]:
6498 * xgselect.c (xg_select):
6499 Prefer assignment to memcpy when either will do.
6501 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6502 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6503 time an item is removed. No need to mark this function 'inline';
6504 the compiler knows better than we do.
6506 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6508 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6509 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6510 to change_frame_size (Bug#12388).
6511 (windowDidResize:): Pass YES to updateFrameSize.
6513 * nsterm.h: Add delay parameter to updateFrameSize.
6515 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6517 Discard killed buffers from deleted window and frame objects.
6518 This reduces an amount of references to killed buffers and
6519 helps GC to reclaim them faster.
6520 * alloc.c (discard_killed_buffers): New function.
6521 (mark_object): Use it for deleted windows and frames.
6522 (mark_object): If symbol's value is set up for a killed buffer
6523 or deleted frame, restore its global binding.
6524 * data.c (swap_in_global_binding): Add GC notice.
6525 (swap_in_symval_forwarding): Use convenient set_blv_where.
6526 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6527 * window.h: ... to here.
6529 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6531 Convenient macro to check whether the buffer is live.
6532 * buffer.h (BUFFER_LIVE_P): New macro.
6533 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6534 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6536 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6538 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6539 composition cases (Bug#12364).
6541 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6542 overhang of succeeding glyphs overlapping box cursor.
6544 * w32term.c (x_draw_glyph_string): Likewise.
6546 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6548 Simplify, document, and port floating-point (Bug#12381).
6549 The porting part of this patch fixes bugs on non-IEEE platforms
6550 with frexp, ldexp, logb.
6551 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6553 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6554 support, by removing commented-out code and briefly listing the
6555 C89 functions excluded. The commented-out stuff was confusing
6556 maintenance, e.g., we thought we needed cbrt but it was commented out.
6557 (logb): Remove decl; no longer needed.
6558 (isfinite): New macro, if not already supplied.
6559 (isnan): Don't replace any existing macro.
6560 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6561 are present on all C89 platforms.
6562 (Ffrexp): Do not special-case zero, as frexp does the right thing
6564 (Flogb): Do not use logb, as it doesn't have the desired meaning
6565 on hosts that use non-base-2 floating point. Instead, stick with
6566 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6567 frexp, to avoid getting an unspecified result.
6569 * xdisp.c (Qinhibit_debug_on_message): Now static.
6571 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6573 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6574 NSBezierPath (Bug#12131).
6576 2012-09-10 Chong Yidong <cyd@gnu.org>
6578 * fns.c (Fdelq, Fdelete): Doc fix.
6580 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6582 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6583 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6585 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6587 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6588 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6591 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6593 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6594 left fringe if the window has a left margin. This avoids leaving
6595 traces of the cursor because its leftmost pixel is not drawn over.
6597 * dispnew.c (update_window_line): When the left margin area of a
6598 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6599 that screen line. (Bug#12277)
6601 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6603 Assume C89 or later for math functions (Bug#12381).
6604 This simplifies the code, and makes it a bit smaller and faster,
6605 and (most important) makes it easier to clean up signal handling
6606 since we can stop worring about floating-point exceptions in
6607 library code. That was a problem before C89, but the problem
6608 went away many years ago on all practical Emacs targets.
6609 * data.c, image.c, lread.c, print.c:
6610 Don't include <math.h>; no longer needed.
6611 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6612 might be autoconfigured, as that never happens.
6614 * doprnt.c (DBL_MAX_10_EXP):
6615 * print.c (DBL_DIG):
6616 Remove. C89 or later always defines these.
6617 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6618 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6619 (arith_error, domain_error, domain_error2):
6620 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6621 no longer needed -- we simply return what C returns. All uses removed.
6622 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6624 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6625 Remove. All uses expanded, as these macros are no longer used
6626 more than once and are now more trouble than they're worth.
6627 (Ftan): Use tan, not sin / cos.
6628 (Flogb): Assume C89 frexp.
6629 (fmod_float): Assume C89 fmod.
6630 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6631 (init_floatfns): Remove. All uses removed.
6633 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6635 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6636 compositeToPoint for OSX < 10.6 (Bug#12390).
6638 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6640 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6641 This produces more-accurate results.
6643 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6645 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6646 changes (Bug#12088).
6648 2012-09-08 Chong Yidong <cyd@gnu.org>
6650 * syntax.c (Fstring_to_syntax): Doc fix.
6652 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6654 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6655 in the internal border.
6656 (x_set_window_size): Remove static variables and their usage.
6657 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6658 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6659 Remove fringe/internal border adjustment (Bug#11052).
6660 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6661 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6662 (ns_fix_rect_ibw): Remove.
6663 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6664 (ns_dumpglyphs_box_or_relief): Ditto.
6665 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6667 (ns_dumpglyphs_image): Ditto.
6668 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6670 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6671 their usage. Add fringe_extended_p and its use as in other terms.
6672 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6673 scroll bar was removed.
6674 (updateFrameSize): New function.
6675 (windowDidResize): Move code to updateFrameSize and call it.
6677 * nsterm.h (EmacsView): Add updateFrameSize.
6679 2012-09-07 Chong Yidong <cyd@gnu.org>
6681 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6683 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6685 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6687 More signal-handler cleanup (Bug#12327).
6688 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6689 Problem introduced when merging patches. Noted by Eli Zaretskii in
6690 <http://bugs.gnu.org/12327#67>.
6691 * floatfns.c: Comment fix.
6692 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6693 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6694 and anyway the declaration is harmless even if SIGDANGER is not defined.
6695 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6696 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6697 source files not surprisingly expected syssignal.h to define, or
6698 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6699 Include <sys/ioctl.h>, for FIONREAD.
6700 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6701 This eliminates a problem whereby other files mysteriously had
6702 to include "syssignal.h" before including "systty.h" if they
6703 wanted to use "#ifdef SIGIO".
6705 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6707 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6709 * w32.c (sigemptyset): Empty the set.
6710 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6712 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6714 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6716 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6717 (mark_object): Likewise for frame objects.
6719 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6721 * syssignal.h (handle_on_main_thread): Always declare,
6722 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6723 This ports to platforms without HAVE_PTHREAD.
6725 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6727 Signal-handler cleanup (Bug#12327).
6728 Emacs's signal handlers were written in the old 4.2BSD style with
6729 sigblock and sigmask and so forth, and this led to some
6730 inefficiencies and confusion. Rewrite these to use
6731 pthread_sigmask etc. without copying signal sets around. Also,
6732 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6733 'signal', and instead use functions that do not attempt to take
6734 over the system name space. This patch causes Emacs's text
6735 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6736 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6737 Do not include <signal.h> or "syssignal.h", as these
6738 modules do not use signals.
6739 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6740 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6741 Do not include <signal.h>, as "syssignal.h" does that for us now.
6742 * atimer.c (sigmask_atimers): New function.
6743 (block_atimers, unblock_atimers): New functions,
6744 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6746 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6747 no longer needed here.
6748 * emacs.c (main): Inspect existing signal handler with sigaction,
6749 so that there's no need to block and unblock SIGHUP.
6750 * sysdep.c (struct save_signal): New member 'action', replacing
6751 old member 'handler'.
6752 (save_signal_handlers, restore_signal_handlers):
6753 Use sigaction instead of 'signal' to save and restore.
6754 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6755 New function. All users of 'signal' modified to use set_sighandler
6756 if they're writeonly, and to use sys_signal if they're read+write.
6757 (emacs_sigaction_init, forwarded_signal): New functions.
6758 (sys_signal): Remove. All uses replaced by calls to sigaction
6759 and emacs_sigaction_init, or by direct calls to 'signal'.
6760 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6761 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6762 all uses replaced by pthread_sigmask etc. calls.
6763 * syssignal.h: Include <signal.h>.
6764 (emacs_sigaction_init, forwarded_signal): New decls.
6765 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6766 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6767 (sigmask, sys_sigmask): Remove; no longer needed.
6768 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6769 (sigblock, sigunblock, sigfree):
6770 (sigsetmask) [!defined sigsetmask]:
6771 Remove. All uses replaced by pthread_sigmask.
6772 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6773 no longer need to be replaced, and its typical old uses
6774 are now done via emacs_sigaction_init and sigaction.
6775 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6776 (sys_sigdel): Remove; unused.
6777 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6779 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6781 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6782 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6784 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6786 Explicitly mark buffer_defaults and buffer_local_symbols.
6787 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6788 mark_local_symbols here.
6789 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6790 since special buffers aren't marked here any more.
6791 (allocate_buffer): Chain new buffer with all_buffers here...
6792 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6794 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6795 (syms_of_buffer): Remove staticpro of the above.
6796 (init_buffer_once): Set names for buffer_defaults and
6797 buffer_local_symbols.
6799 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6801 Use bool for booleans in font-related modules.
6802 * font.c (font_intern_prop, font_style_to_value)
6803 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6804 (generate_otf_features, font_check_otf_features, font_check_otf)
6805 (font_match_p, font_list_entities, font_at):

6807 (fontset_find_font, Fset_fontset_font)
6808 (face_suitable_for_char_p) [0]:
6809 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6810 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6811 (m17n_flt_initialized, ftfont_shape_by_flt):

6813 * nsfont.m (nsfont_draw):
6814 * w32font.c (w32font_draw):
6815 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6816 Use bool for booleans.
6817 * font.h: Adjust to above API changes.
6818 (struct font, struct font_driver, struct font_driver_list):
6819 Use bool for booleans.
6820 (struct font): Remove useless member encoding_type.
6822 * fontset.c, xftfont.c: Omit unnecessary static decls.
6824 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6826 * alloc.c (mark_object): Revert window marking code
6827 since it's unsafe for the Fset_window_configuration.
6829 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6831 Fix race conditions with signal handlers and errno (Bug#12327).
6832 Be more systematic about preserving errno whenever a signal
6833 handler returns, even if it's not in the main thread. Do this by
6834 renaming signal handlers to distinguish between signal delivery
6835 and signal handling. All uses changed.
6836 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6837 * data.c (deliver_arith_signal): Rename from arith_error.
6838 * dispnew.c (deliver_window_change_signal): Rename from
6839 window_change_signal.
6840 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6841 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6842 * keyboard.c (deliver_input_available_signal): Rename from
6843 input_available_signal.
6844 (deliver_user_signal): Rename from handle_user_signal.
6845 (deliver_interrupt_signal): Rename from interrupt_signal.
6846 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6847 (deliver_child_signal): Rename from sigchld_handler.
6848 * atimer.c (handle_alarm_signal):
6849 * data.c (handle_arith_signal):
6850 * dispnew.c (handle_window_change_signal):
6851 * emacs.c (handle_fatal_signal, handle_danger_signal):
6852 * keyboard.c (handle_input_available_signal):
6853 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6854 * process.c (handle_pipe_signal, handle_child_signal):
6855 New functions, with the actual signal-handling code taken from the
6856 original respective signal handlers, sans the sporadic attempts to
6857 preserve errno, since that's now done by handle_on_main_thread.
6858 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6859 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6860 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6862 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6863 Move initialization of main_thread to sysdep.c's init_signals.
6864 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6865 our usage, and simplifies the mainline code.
6866 (record_child_status_change): New static function, as a helper
6867 for handle_child_signal, and with most of the old child handler's
6869 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6870 (handle_child_signal): Use the above.
6871 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6872 Moved here from emacs.c.
6873 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6874 code moved here from emacs.c's main function.
6875 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6876 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6877 This lets callers save and restore errno properly.
6879 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6881 Remove redundant or unused things here and there.
6882 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6883 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6884 * editfns.c (Fcompare_buffer_substrings): Likewise.
6885 * frame.h (struct terminal, struct font_driver_list):
6886 Remove redundant declarations.
6887 * window.h (Qleft, Qright): Likewise.
6889 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6891 Do not mark objects from deleted buffers, windows and frames.
6892 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6893 (mark_object): Likewise for windows and frames.
6895 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6897 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6898 buffer_defaults and buffer_local_symbols as valid objects.
6899 Return special value to denote them.
6901 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6903 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6904 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6905 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6906 (file_name_absolute_p, Fsubstitute_in_file_name):
6907 (check_executable, check_writable, Ffile_accessible_directory_p)
6908 (Fset_file_selinux_context, Fdefault_file_modes)
6909 (Finsert_file_contents, choose_write_coding_system)
6910 (Fwrite_region, build_annotations, a_write, e_write)
6912 * filelock.c (boot_time_initialized, get_boot_time)
6913 (get_boot_time_1, lock_file_1, within_one_second):
6914 * floatfns.c (in_float):
6915 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6916 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6917 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6918 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6919 * window.c (compare_window_configurations):
6920 Use bool for booleans.
6921 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6922 (Fdefault_file_modes): Now mode_t, not int, for modes.
6923 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6924 (internal_delete_file): Now returns void, not a (boolean) int,
6925 since nobody was looking at the return value.
6926 * lisp.h, window.h: Adjust to above API changes.
6928 * xdisp.c (set_message): Simplify and reindent last change.
6930 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6932 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6934 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6936 * eval.c (call_debugger): Make the function non-static so that we
6937 can call it from set_message.
6939 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6940 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6942 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6944 Give more-useful info on a fatal error (Bug#12328).
6945 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6946 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6947 of doing the work ourselves.
6948 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6949 do most of the work.
6950 (fatal_error_backtrace): New function, taken from the guts
6951 of the old fatal_error_signal, but with a new option to output
6953 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6954 info about the signal than just its number.
6955 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6956 * sysdep.c: Include <execinfo.h>
6957 (emacs_backtrace): New function, taken partly from the previous
6958 code of the 'die' function.
6959 (emacs_abort): Call fatal_error_backtrace rather than abort.
6961 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6963 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6964 eager (load-time) macro-expansion.
6965 * lisp.mk (lisp): Add macroexp.
6967 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6969 Simplify redefinition of 'abort' (Bug#12316).
6970 Do not try to redefine the 'abort' function. Instead, redo
6971 the code so that it calls 'emacs_abort' rather than 'abort'.
6972 This removes the need for the NO_ABORT configure-time macro
6973 and makes it easier to change the abort code to do a backtrace.
6974 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6975 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6976 Remove; sysdep.c's emacs_abort now takes its place.
6977 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6978 'abort' changed to use 'emacs_abort'.
6979 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6980 (abort) [!defined abort]: Rename to ...
6981 (emacs_abort): ... new name.
6982 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6983 the place of the old 'abort' in emacs.c.
6984 * w32.c, w32fns.c (abort): Do not #undef.
6985 * w32.c (emacs_abort): Rename from w32_abort.
6987 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6989 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6990 offsets[j].dv, since the y axis of the screen coordinates points
6991 down, while the y axis of the font definition coordinates points
6992 up. This fixes display of Arabic diacritics such as KASRA and
6993 KASRATAN. (Bug#11860)
6995 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6997 Be more systematic about _setjmp vs setjmp.
6998 * alloc.c (test_setjmp, mark_stack):
6999 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
7000 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
7001 (png_load, my_error_exit, jpeg_load):
7002 * process.c (send_process_trap, send_process):
7003 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
7004 The underscored versions are up to 30x faster on some hosts.
7005 Formerly, the code used setjmp+longjmp sometimes and
7006 _setjmp+_longjmp at other times, with no particular reason to
7007 prefer setjmp+longjmp.
7009 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
7011 Fix minor problem found by static checking.
7012 * buffer.c (Fdelete_all_overlays): Return nil.
7014 2012-09-03 Martin Rudalics <rudalics@gmx.at>
7016 * buffer.c (Fdelete_all_overlays): New function.
7018 2012-09-03 Chong Yidong <cyd@gnu.org>
7020 * gtkutil.c: Add extern decl for Qxft.
7022 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
7024 * emacs.c, eval.c: Use bool for boolean.
7025 * emacs.c (initialized, inhibit_window_system, running_asynch_code):

7036 All callers changed.
7037 * eval.c (interactive_p): Omit always-true boolean argument
7038 EXCLUDE_SUBRS_P. All callers changed.
7039 * dispextern.h, lisp.h: Reflect above API changes.
7040 * firstfile.c (dummy): Use the address of 'main', whose signature
7041 won't change, instead of the address of 'initialize', whose
7042 signature just changed from int to bool.
7043 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
7044 * msdos.c (fatal_error_in_progress): ... from here.
7045 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
7047 (redisplay_internal, unwind_redisplay): Simply clear
7048 REDISPLAYING_P when unwinding, instead of saving its previous,
7049 always-false value and then restoring it.
7051 Clean up some extern decls.
7052 Mostly, this hoists extern decls out of .c files and into .h files.
7053 That way, we're more likely to catch errors if the interfaces change.
7054 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
7055 declare xg_mark_data.
7056 * dispextern.h (x_frame_parm_handlers):
7058 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
7059 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
7060 (Qultra_bold, Qoblique, Qitalic):
7061 Move extern decl here from .c file.
7062 * alloc.c (xg_mark_data) [USE_GTK]:

7072 * widget.c (free_frame_faces):
7073 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
7074 * xfont.c (x_clear_errors):
7075 * xterm.c (x_frame_parm_handlers):
7076 Remove now-redundant extern decls.
7077 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
7078 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
7080 * xfaces.c: Remove unnecessary static decls.
7081 * xterm.c (updating_frame): Remove decl of nonexistent object.
7083 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
7084 when building globals.h, as the objects that are not built on
7085 this host are not needed to compile C files on this host.
7087 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
7089 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

7103 (make_buffer_string, make_buffer_string_both)
7104 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
7105 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)

7117 * keyboard.c (decode_timer):
7118 Use bool for boolean.

7124 * keymap.c (push_key_description): Print M-TAB as C-M-i
7127 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
7129 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
7130 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

7135 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
7137 2012-09-01 Eli Zaretskii <eliz@gnu.org>
7139 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
7140 more than one grapheme cluster passed to the shaper: compute the
7141 offset adjustment values separately for each cluster. (Bug#11860)
7143 * image.c: Restore mistakenly removed inclusion of w32.h. Without
7144 it, GCC doesn't see prototypes of w32_delayed_load, and complains
7145 about implicit conversions from integer to pointer.
7147 2012-09-01 Daniel Colascione <dancol@dancol.org>
7149 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
7150 system used too early.
7152 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
7154 Better seed support for (random).

7183 * process.c: Include TERM_HEADER instead of listing all possible
7184 window-system headers.
7186 * nsterm.h: Remove declarations now in frame.h.
7187 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
7189 * menu.c: Include TERM_HEADER instead of listing all possible
7190 window-system headers.
7192 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
7195 * keyboard.c: Include TERM_HEADER instead of listing all possible
7196 window-system headers.
7198 * image.c: Include TERM_HEADER instead of listing all possible
7199 window-system headers. Declare Vlibrary_cache when compiling for
7202 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
7203 window system declarations.
7205 * frame.h: Move common functions here: set_frame_menubar,
7206 x_set_window_size, x_sync, x_get_focus_frame,
7207 x_set_mouse_position, x_set_mouse_pixel_position,
7208 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,
7209 x_char_width, x_char_height, x_pixel_width, x_pixel_height,

7229 the current window system; include in list of objects to link into
7232 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
7234 Remove mark_ttys function and fix tty_display_info initialization.
7235 * lisp.h (mark_ttys): Remove prototype.
7236 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
7237 to mark_ttys because all possible values of 'top_frame' slot are
7238 the frames which are reachable from Vframe_list.
7239 * term.c (mark_ttys): Remove.
7240 (init_tty): Safely initialize 'top_frame' slot with Qnil.
7242 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
7244 Change struct frame bitfields from unsigned char to unsigned.
7245 * frame.h (struct frame): Change type of 'display_preempted',

7247 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
7248 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
7249 bitfields from unsigned char to unsigned.
7251 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
7253 Remove unused member of struct x_output and struct w32_output.

7257 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
7259 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
7260 does not become zero (Bug#12234).
7262 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
7264 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
7265 for GCC 4.7.1 x86-64.
7267 2012-08-30 Glenn Morris <rgm@gnu.org>
7269 * lread.c (init_lread): For out-of-tree builds, only add the
7270 source directory's site-lisp dir to the load-path if it exists,
7271 consistent with in-tree builds. (Bug#12302)
7273 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
7275 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
7276 button_values to NULL. Call setStykeMask so dialogs get a close button.
7277 (windowShouldClose:): Set window_closed.
7278 (dealloc): New member, free button_values.
7279 (process_dialog:): Make member function. Remove window argument,
7280 replace window with self. Count buttons and allocate and store values
7282 (addButton:value:row:): value is int with the name tag. Call setTag
7283 with tag. Remove return self, declare return value as void.
7284 (addString:row:): Remove return self, declare return value as void.
7285 (addSplit): Remove return self, declare return value as void.
7286 (clicked:): Remove return self, declare return value as void.
7287 Set dialog_return to button_values[seltag]. Code formatting change.
7288 (initFromContents:isQuestion:): Adjust call to process_dialog.
7289 Code formatting change.
7290 (timeout_handler:): Set timer_fired to YES.
7291 (runDialogAt:): Set timer_fired to NO.
7292 Handle click on close button as quit.
7294 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
7295 Add window_closed and button_values. Add void as return value for
7296 add(Button|String|Split). addButton takes int instead of Lisp_Object.
7297 Add process_dialog as new member.
7299 2012-08-28 Eli Zaretskii <eliz@gnu.org>
7301 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
7302 is not one of the heaps we manage. (Bug#12242)
7304 2012-08-28 Glenn Morris <rgm@gnu.org>
7306 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)

7317 * buffer.c (Fset_buffer_major_mode): Signal an error
7318 if the buffer is dead.
7319 (Fother_buffer, other_buffer_safely): Remove redundant
7322 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
7324 Always use set_buffer_if_live to restore original buffer at unwind.
7325 * buffer.h (record_unwind_current_buffer): New function.
7326 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:
7327 * keyboard.c, keymap.c, minibuf.c, print.c, process.c, textprop.c:
7328 * undo.c, window.c: Adjust users.
7329 * buffer.c (set_buffer_if_live): Fix comment.
7331 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
7333 Fix usage of set_buffer_internal.
7334 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
7335 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
7336 * coding.c (decode_coding): Omit redundant test.
7337 * fileio.c (decide_coding_unwind): Likewise.
7338 * fns.c (secure_hash): Likewise.

7340 * keyboard.c (command_loop_1): Likewise.
7341 * print.c (PRINTFINISH): Likewise.
7342 * xdisp.c (run_window_scroll_functions): Use set_buffer_internal.
7344 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

7363 Use bool for boolean.
7364 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
7365 and remove last int (actually boolean) argument, which was always 0.
7366 All callers changed.
7367 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
7368 * dispextern.h (struct composition_it): Use bool for boolean.
7369 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
7370 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
7371 * dired.c (file_name_completion):
7372 Use bool for boolean. (This was missed in an earlier change.)
7374 2012-08-27 Martin Rudalics <rudalics@gmx.at>
7376 * window.c (Fset_window_configuration): Revert first part of
7379 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
7381 * nsterm.h (NSPanel): New class variable dialog_return.
7383 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
7384 Initialize dialog_return.
7385 (windowShouldClose:): Use stop instead of stopModalWithCode.
7386 (clicked:): Ditto, and also set dialog_return (Bug#12258).
7387 (timeout_handler:): Use stop instead of abortModal. Send a dummy
7389 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

7434 Use bool for booleans.
7435 * coding.h, lisp.h: Reflect above API changes.
7436 * coding.c: Remove unnecessary static function decls.
7437 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
7438 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
7439 not a boolean 'int', since callers never look at the return value.
7440 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
7441 * coding.h (decoding_buffer_size, encoding_buffer_size)
7442 (emacs_mule_string_char): Remove unused extern decls.
7443 (struct iso_2022_spec, struct coding_system):
7444 Use 'unsigned int : 1' for boolean fields, since there's more than one.
7445 (struct emacs_mule_spec): Remove unused field 'full_support'.
7446 All initializations removed.
7447 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
7449 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7451 Fix spare memory change (Bug#12286).
7452 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
7453 (valid_lisp_object_p): Likewise.
7455 2012-08-27 Martin Rudalics <rudalics@gmx.at>
7457 * window.c (Fset_window_configuration): Record any window's old
7458 buffer if it's replaced (see Bug#8789). If the new current
7459 buffer doesn't appear in the selected window, go to its old
7462 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7464 Special MEM_TYPE_SPARE to denote reserved memory.
7465 * alloc.c (enum mem_type): New memory type.
7466 (refill_memory_reserve): Use new type for spare memory.
7467 This prevents live_cons_p and live_string_p from incorrect
7468 detection of uninitialized objects from spare memory as live.
7470 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
7473 * Makefile.in (.PHONY): versioclean -> versionclean.
7475 Remove unused external symbols.
7476 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
7477 * window.c (Qwindow_valid_p, decode_valid_window):
7478 Now static, not extern.
7479 * data.c (Qinterval): Remove; unused.
7480 (syms_of_data): Do not define 'interval'.
7481 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
7482 * window.h (decode_valid_window):
7485 * character.c, charset.c, chartab.c: Use bool for booleans.

7496 (map_sub_char_table):
7497 Use bool for boolean.
7498 * character.c (str_to_unibyte): Omit last boolean argument; it was
7499 always 0. All callers changed.
7500 * character.h, charset.h: Adjust to match previous changes.
7501 * character.h (char_printable_p): Remove decl of nonexistent function.
7502 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
7503 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
7504 are all boolean, so make them single-bit bitfields.
7506 * lisp.h (ASET): Remove attempt to detect side effects.
7507 It was meant to be temporary and it often doesn't work,
7508 because when IDX has side effects the behavior of IDX==IDX
7509 is undefined. See Stefan Monnier in
7510 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
7512 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
7514 * lisp.h (functionp): New function (extracted from Ffunctionp).
7515 (FUNCTIONP): Use it.
7516 * eval.c (Ffunctionp): Use it.
7518 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7520 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7521 as that's faster and simpler than static storage. Don't bother
7522 with the g_main_context_query overhead if g_main_context_pending
7523 says no events are pending.
7524 (gfds, gfds_size): Remove these static vars.
7525 (xgselect_initialize): Remove; no longer needed.
7526 All uses and decls removed.
7528 * emacs.c (fatal_error_signal_hook): Remove.
7529 All uses removed. This leftover from old code was always 0.
7531 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
7532 * casefiddle.c (casify_object, casify_region):
7533 * casetab.c (set_case_table):
7534 * category.c, category.h (word_boundary_p):
7535 * category.h (CHAR_HAS_CATEGORY):
7536 Use bool for booleans, instead of int.
7538 2012-08-25 Eli Zaretskii <eliz@gnu.org>
7540 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
7542 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7544 On assertion failure, print backtrace if available.
7545 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
7546 (die) [ENABLE_CHECKING]: Print a backtrace if available.
7547 * Makefile.in (LIB_EXECINFO): New macro.
7550 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
7551 * bytecode.c (exec_byte_code):
7552 * callint.c (check_mark, Fcall_interactively):
7553 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
7554 (getenv_internal, sync_process_alive, call_process_exited):
7555 * lisp.h (USE_SAFE_ALLOCA):
7556 Use bool for booleans, instead of int.
7557 * lisp.h, process.h: Adjust prototypes to match above changes.
7558 * callint.c (Fcall_interactively): Don't assume the mark's
7559 offset fits in 'int'.
7561 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7563 * buffer.c, buffer.h: Use bool for boolean.

7570 (mmap_enlarge, mmap_set_vars):
7571 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7572 Use bool for booleans, instead of int.
7573 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7574 since the 1-or-0 return value is always ignored anyway.
7575 (mmap_initialized_p):
7576 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7577 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7579 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7581 * bidi.c: Use bool for boolean.
7582 This is a bit more readable, and makes the text segment of bidi.o
7583 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7584 Presumably it's faster too.
7585 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
7587 (bidi_cache_find_level_change, bidi_cache_iterator_state)
7588 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)

7590 (bidi_explicit_dir_char, bidi_level_of_next_char)
7591 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7592 Use bool for booleans, instead of int.
7593 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7594 (bidi_unshelve_cache): Adjust decls to match code.
7596 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7598 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7601 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7603 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7604 * atimer.h: Include <stdbool.h>.
7606 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7608 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7609 compile time tests instead of run time tests on systems that do
7611 (FRAME_MAC_P): Remove leftover from deleted code.
7612 * frame.c (syms_of_frame): Remove leftover from deleted code.
7614 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
7616 * nsterm.m (insertText:): Don't clear modifiers if code is space.
7618 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7620 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7621 Otherwise, the compiler complains about (A?B:C) where B is void
7622 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7623 (fontset_add): Return void, for FONTSET_ADD.
7625 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7627 * alloc.c: Use bool for booleans.
7628 (gc_in_progress, abort_on_gc)
7629 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7630 (dont_register_blocks) [GC_MALLOC_CHECK]:
7631 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.

7633 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
7634 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7635 (mark_stack, valid_pointer_p, make_pure_string)
7636 (Fgarbage_collect, survives_gc_p, gc_sweep):
7637 Use bool for booleans, instead of int.
7638 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7639 Remove unused local.
7640 * alloc.c (PURE_POINTER_P):
7641 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7642 * editfns.c (Fformat):
7643 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7645 * fns.c (sweep_weak_table):
7646 * lisp.h (suppress_checking, push_message, survives_gc_p)
7647 (make_pure_string, gc_in_progress, abort_on_gc):
7648 * lread.c (readchar, read1):
7649 * print.c (Fprin1_to_string):
7650 * xdisp.c (push_message):
7651 Use bool for booleans affected directly or indirectly by
7654 Make recently-introduced setters macros.
7655 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7656 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7657 (set_fontset_default, set_fontset_fallback): Rename from their
7658 upper-case counterparts, and make them functions rather than macros.
7659 This is more consistent with the other recently-introduced setters.
7660 These don't need to be inline, since they're local.
7662 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7664 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7665 the loop (Bug#12247).
7667 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7669 * lisp.h (vcopy): Use memcpy rather than our own loop.
7670 This fixes a performance regression introduced by the recent
7671 addition of vcopy. This means 'vcopy' will need to be modified
7672 for a copying collector, but that's OK. Also, tighten the
7673 checking in the assertion.
7675 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7677 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7678 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7679 non-base glyph for the width of the base character, according to
7680 what x_draw_composite_glyph_string_foreground expects.
7681 Generate WADJUST value according to composition_gstring_width's
7682 expectations, to produce correct width of the composed character.
7683 Reverse the sign of the DU offset produced by ScriptPlace.
7685 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7687 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7689 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7691 Avoid direct writes to contents member of struct Lisp_Vector.
7692 * lisp.h (vcopy): New function to copy data into vector.
7693 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7694 * fns.c (Ffillarray): Use ASET.
7695 * keyboard.c (timer_check_2): Use AREF and ASET.
7696 (append_tool_bar_item, Frecent_keys): Use vcopy.
7697 * lread.c (read_vector): Use ASET.
7698 * msdos.c (Frecent_doskeys): Use vcopy.
7699 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7700 (Finternal_merge_in_global_face): Use ASET and vcopy.
7701 * xfont.c (xfont_list_pattern): Likewise.
7703 2012-08-21 Martin Rudalics <rudalics@gmx.at>
7705 * window.c (Fwindow_point): For the selected window always return
7706 the position of its buffer's point.
7707 (Fset_window_point): For the selected window always go in its
7708 buffer to the specified position.
7710 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7712 Setter macros for fontsets.
7713 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7714 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7715 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7718 2012-08-20 Glenn Morris <rgm@gnu.org>
7720 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7721 Don't assume that `ln -f' works.
7723 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7725 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
7726 and later about non-assignments with no effect. See discussion at

7751 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
7752 (set_hash_hash, set_hash_index): Rename with _slot suffix.

7769 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7771 Rely on <config.h> + <unistd.h> to declare 'environ',
7772 as gnulib does this if the system doesn't.
7773 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7774 Remove declaration. MS-Windows declares it on stdlib.h which is

7777 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.

7808 * chartab.c, lisp.h (char_table_set, char_table_set_range):
7809 Return void, not Lisp_Object. Otherwise, the compiler
7810 complains about (A?B:C) where B is void and C is Lisp_Object
7811 when compiling CHAR_TABLE_SET, due to the recent change to
7812 the API of sub_char_table_set_contents.

8642 2012-08-04 Eli Zaretskii <eliz@gnu.org>
8644 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
8645 * w32.c (init_environment): Change the default values of many
8646 environment variables in dflt_envvars[] to NULL, to avoid pushing
8647 them into environment when they were not already defined.
8648 Remove the code that deletes site-lisp subdirectories from the default
8649 value of EMACSLOADPATH, as it is no longer needed.
8650 (check_windows_init_file): Now external, not static.
8651 Use Vload_path as is, without adding anything, as this function is now
8652 called when Vload_path is already set up.
8654 * w32.h (check_windows_init_file): Add prototype.
8656 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
8657 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
8658 compatibility with Posix platforms.
8659 (main): Move the call to check_windows_init_file to here from
8661 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
8662 any, in the DEFALT argument into the root of the Emacs build or
8663 installation tree, as appropriate.
8665 * callproc.c (init_callproc_1): Call decode_env_path instead of
8666 doing its equivalent by hand.
8667 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
8668 the code that sets Vexec_path run on MS-Windows.
8670 * lread.c (init_lread): Add comments to #ifdef's.
8672 * msdos.c (dos_set_window_size, IT_update_begin)
8673 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
8674 instead of direct references.

8680 Now constants, not macros.
8682 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
8684 Remove unnecessary casts involving pointers.
8685 These casts are no longer needed now that we assume C89 or later,
8686 since they involve casting to or from void *.
8687 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
8688 (make_pure_float, make_pure_vector):
8689 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

8699 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
8700 Remove unnecessary pointer casts.
8701 * alloc.c (record_xmalloc): New function.
8702 * lisp.h (record_xmalloc): New decl.
8703 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8704 more like a function. This is because the pointer cast is not
8705 needed. All uses changed.
8706 * print.c (print_string, print_error_message): Avoid length recalc.
8708 Improve fix for macroexp crash with debugging (Bug#12118).
8709 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
8710 ARRAY_MARK_FLAG when checking subscripts, because ASET is
8711 not supposed to be invoked from the garbage collector.
8712 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
8713 (gc_aset): New function, which is like ASET but can be
8714 used in the garbage collector.
8715 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

8725 <g_b_init_create_symbolic_link>: New static flags.
8726 (globals_of_w32): Initialize them to zero.
8727 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
8728 (map_w32_filename): Improve commentary. Simplify switch.
8729 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
8730 headers (most versions of MinGW w32api don't).
8731 (get_security_info, create_symbolic_link)
8732 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
8734 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
8735 in the argument file name.

8738 (sys_rename): Diagnose renaming of a symlink when the user doesn't
8739 have the required privileges.
8740 (get_file_security_desc_by_name): Rename from
8741 get_file_security_desc.
8742 (stat_worker): New function, with most of the guts of 'stat', and
8743 with addition of handling of symlinks and support for 'lstat'.
8744 If possible, get file's attributes and security information by
8745 handle, not by name. Produce S_IFLNK bit for symlinks, when
8746 called from 'lstat'.
8747 (stat, lstat): New functions, call 'stat_worker'.
8748 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8749 symlinks when the underlying filesystem supports them.
8751 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
8753 Fix macroexp crash on Windows with debugging (Bug#12118).
8754 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8755 checking subscripts; problem introduced with the recent
8756 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8757 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8758 since it's used in non-static inline functions now.
8760 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
8761 Don't assume buffer size fits in 'int'. Remove unused local.

8778 * category.c (CATEGORY_INLINE):
8779 * character.c (CHARACTER_INLINE):
8780 * charset.c (CHARSET_INLINE):
8781 * composite.c (COMPOSITE_INLINE):
8782 * dispnew.c (DISPEXTERN_INLINE):
8783 * sysdep.c (SYSTIME_INLINE):
8784 Define to EXTERN_INLINE, so that the corresponding functions
8785 are compiled into code.
8786 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
8787 (INLINE_HEADER_END): New macros.
8788 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

8808 hard-coding the path separator.
8810 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
8812 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
8813 This how ASET and AREF are supposed to work, and makes
8814 it easier to think about future improvements. See
8815 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
8816 * charset.h (set_charset_attr): New function.

9069 * s/aix4-2.h (sigmask): No need to undefine it, since syssignal.h
9070 does that unconditionally. Remove file, which is now empty.
9072 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
9075 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

9090 (CHAR_TABLE_STANDARD_SLOTS, CHAR_TABLE_EXTRA_SLOTS):
9091 Move to after the definition of struct Lisp_Char_Table,
9092 since the former now needs that type defined.

9193 * w32inevt.c: Include w32inevt.h.
9194 (w32_read_console_input): New inline function, calls either
9195 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
9196 w32_console_unicode_input.
9197 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
9198 (w32_kbd_patch_key, key_event): Use the codepage returned by
9199 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
9200 (key_event): use uChar.UnicodeChar only if
9201 w32_console_unicode_input is non-zero.

9231 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
9232 enumeration constants, as PURE and HEAP are too general, and clash
9233 with other headers and sources, such as gmalloc.c and the
9234 MS-Windows system headers. All users changed.
9236 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9238 Revert last save_excursion_save and save_excursion_restore changes.
9239 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

9249 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
9251 Improve GDB symbol export (Bug#12036).
9252 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
9253 arms of an 'if', not using conditional expressions; otherwise GDB
9254 complains about the types in the unevaluated arm when the argument
9255 is an integer literal.
9256 (xgetint): Simplify expression.
9257 * alloc.c (gdb_make_enums_visible): New constant. This ports to
9258 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
9259 Zaretskii in <http://bugs.gnu.org/12036#13>.
9260 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
9261 needed now that we have gdb_make_enums_visible.
9262 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
9263 (enum enum_USE_LSB_TAG):
9264 New enum types, packaging up enums that need to be exported to GDB.
9266 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

9282 * xdisp.c (syms_of_xdisp): Likewise.
9283 * xfns.c (syms_of_xfns): Likewise.
9285 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9287 Fast save_excursion_save and save_excursion_restore.
9288 * lisp.h (struct Lisp_Excursion): New data type.
9289 (PVEC_EXCURSION): New pseudovector type.
9290 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
9291 to deal with it. Adjust comments.

9302 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
9304 Fix export of symbols to GDB (Bug#12036).
9305 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
9306 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
9307 emacs.c, as this is a more-suitable home. Had this been done earlier
9308 the fix for 12036 would have avoided some of the problems noted in
9309 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
9310 would have been more obvious.
9311 * emacs.c: Do not include <verify.h>; no longer needed.
9312 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
9313 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
9314 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

9319 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
9320 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
9321 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
9322 not be usable in #if. This simplifies things.
9324 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
9326 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
9328 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
9330 Simplify export of symbols to GDB (Bug#12036).
9331 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
9332 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
9333 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
9334 Adjust to changes in lisp.h and emacs.c, by using
9335 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
9336 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
9337 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
9338 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
9339 instead of gdb_valbits.
9340 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
9341 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
9342 instead of gdb_array_mark_flag.
9343 (xboolvector): Get size from $->size, not $->header.size.
9344 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
9345 (xreload, hook-run, hookpost-run): Remove.
9346 * emacs.c: Include <verify.h>.
9347 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
9348 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
9350 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
9351 (gdb_USE_LSB_TAG): New enum constants.
9352 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9353 Also define these as enum constants, so they're visible to GDB.
9354 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
9355 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
9356 as constants, so they're visible to GDB.
9357 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
9358 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
9359 Now enum constants, not macros, so they're visible to GDB.
9360 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
9361 more convenient now. All uses changed.
9362 (VALMASK) [USE_LSB_TAG]: Also define in this case.
9363 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
9365 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
9367 Explicitly free restriction data that are not needed anymore.

9370 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
9372 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
9373 add argument, tune behavior, and adjust all callers.
9375 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
9377 Use typedef for EMACS_INT, EMACS_UINT.
9378 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
9379 than macros. This simplifies debugging in the usual case, since
9380 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
9381 and it allows expressions involving EMACS_INT casts.
9382 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
9384 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

9392 that FOCUS-FRAME can be omitted.
9394 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
9396 Adjust buffer text indirection counters at the end of Fkill_buffer.
9397 * buffer.c (Fkill_buffer): Adjust indirection counters when the
9398 buffer is definitely dead. This should really fix an issue reported
9399 by Christoph Scholtes again. (Bug#12007).
9400 (init_buffer_once): Initialize indirection counters of
9401 buffer_defaults and buffer_local_symbols (for sanity and safety).
9403 2012-07-24 Eli Zaretskii <eliz@gnu.org>
9405 * xdisp.c (init_iterator): Don't compute dimensions of truncation
9406 and continuation glyphs on tooltip frames, leave them at zero.
9407 Avoids continued lines in tooltips. (Bug#11832)
9409 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
9411 Simplify copy_overlay.
9412 * buffer.c (copy_overlay): Simplify. Use build_marker.

9418 or invalid. (Bug#12025)
9420 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
9421 it signals an error when a tooltip frame is being created.
9423 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9425 Cleanup miscellaneous objects allocation and initialization.
9426 * alloc.c (allocate_misc): Change to static. Add argument to
9427 specify the subtype. Adjust comment and users.
9428 (build_overlay): New function.
9429 * buffer.c (copy_overlays, Fmake_overlay): Use it.
9430 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
9431 (allocate_misc): Remove prototype.
9432 (build_overlay): Add prototype.
9434 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9436 Swap buffer text indirection counters in Fbuffer_swap_text.
9437 * buffer.c (Fbuffer_swap_text): Swap indirections too.
9438 This avoids crash reported by Christoph Scholtes at
9439 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
9441 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
9443 * nsmenu.m (Popdown_data): New struct.
9444 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
9446 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
9447 (initWithContentRect): Make imgView and contentView non-static
9448 and autorelease them. Also autorelease img and matrix (Bug#12005).
9449 (dealloc): Remove (Bug#12005).
9451 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
9453 Adjust consing_since_gc when objects are explicitly freed.
9454 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
9455 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.
9456 (free_cons, free_misc): Subtract object size from consing_since_gc.
9458 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
9460 Simplify and cleanup markers positioning code.
9461 * marker.c (attach_marker): More useful eassert.
9462 (live_buffer, set_marker_internal): New function.
9463 (Fset_marker, set_marker_restricted): Use set_marker_internal.
9464 (set_marker_both, set_marker_restricted_both): Use live_buffer.
9466 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
9468 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
9469 as it's limited by the amount of memory, not by INT_MAX.
9471 2012-07-21 Eli Zaretskii <eliz@gnu.org>
9473 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
9474 in special-event-map. See the discussion at
9475 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
9478 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning

10197 * s/aix4-2.h (unix): Remove; no longer needed.
10199 EMACS_TIME simplification (Bug#11875).
10200 This replaces macros (which typically do not work in GDB)

10202 The functional style also makes code easier to read and maintain.
10203 * systime.h: Include <sys/time.h> on all hosts, not just if
10204 WINDOWSNT, since 'struct timeval' is needed in general.
10205 (EMACS_TIME): Now a typedef, not a macro.

10239 (menu_separator_name_p):
10240 * nsmenu.m (ns_update_menubar):
10241 Prefer memcmp to strncmp when either will do.
10242 * nsterm.m: Include <ftoastr.h>.
10244 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
10245 Prefer snprintf to strncpy.
10246 * nsterm.m (ns_term_init):
10247 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
10248 * nsterm.m (ns_term_init):
10249 Avoid the need for strncpy, by using build_string or
10250 make_unibyte_string directly. Use dtoastr, not snprintf.
10251 * process.c (Fmake_network_process): Diagnose service names that
10252 are too long, rather than silently truncating them or creating
10253 non-null-terminated names.
10254 (Fnetwork_interface_info): Likewise, for interface names.
10255 * sysdep.c (system_process_attributes) [GNU_LINUX]:
10256 Prefer sprintf to strncat.

10269 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
10270 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR

10285 (build_pure_c_string): New function, defined as static inline. This
10286 provides a better opportunity to optimize away calls to strlen when
10287 the function is called with compile-time constant argument.
10288 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
10289 argument, adjust users accordingly. Use build_pure_c_string where

10292 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
10293 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.

10322 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
10323 We include usg5-4-common.h, which defines them both.
10325 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
10326 O_RDONLY already includes it).
10328 Stop ns builds setting the EMACSLOADPATH environment variable.
10329 * nsterm.m (ns_load_path): Rename from ns_init_paths.
10330 Now it does not set EMACSLOADPATH, just returns the load-path string.
10331 * nsterm.h: Update accordingly.
10332 * lread.c [HAVE_NS]: Include nsterm.h.
10333 (init_lread) [HAVE_NS]: Use ns_load_path.

10343 (ns_init_paths): Do not set EMACSPATH.

10352 * process.c (wait_reading_process_output): 'waitchannels' was unset
10353 when read_kbd || !NILP (wait_for_cell); fix this.

10366 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
10367 Add decls with ATTRIBUTE_CONST.
10369 Minor improvements to make_formatted_string.
10370 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
10371 where int is good enough, as vsprintf returns an int.
10372 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
10374 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10376 Use make_formatted_string to avoid double length calculation.
10377 * lisp.h (make_formatted_string): New prototype.
10378 * alloc.c (make_formatted_string): New function.

10399 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
10401 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10403 Move marker debugging code under MARKER_DEBUG.
10404 * marker.c (MARKER_DEBUG): Move marker debugging code under
10405 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
10406 for bootstrap with --enable-checking (~3x slowdown reported
10407 by Juanma Barranquero <lekktu@gmail.com>).
10408 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
10410 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
10412 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
10413 See <http://bugs.gnu.org/11825#29>.
10415 2012-07-08 Eli Zaretskii <eliz@gnu.org>
10417 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
10418 has no font, use the frame's font. (Bug#11813)
10419 (display_line): Add commentary about displaying truncation glyphs
10421 (produce_special_glyphs): Move here from term.c.
10423 * term.c (produce_special_glyphs): Move to xdisp.c.
10425 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
10428 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
10430 * xdisp.c (display_line): Avoid warning about implicit declaration
10433 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
10435 * lisp.h: Remove empty conditional.
10437 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10439 * lread.c (load_path_check): Now static.
10441 Fix some minor --with-ns problems found by static checking.
10442 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
10443 (x_set_font) [!HAVE_X_WINDOWS]:
10444 * image.c (xpm_load_image) [HAVE_NS]:
10445 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
10446 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
10447 Remove unused local.
10448 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
10449 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
10450 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
10451 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
10452 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
10453 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
10454 Fix pointer signedness problem.
10455 * xfaces.c (FRAME_X_FONT_TABLE):
10456 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
10458 2012-07-07 Glenn Morris <rgm@gnu.org>
10460 * lread.c (load_path_check): New function, split from init_lread.
10461 (init_lread): Reorganize. Motivation:
10462 If EMACSLOADPATH is set, check/warn about that rather than the
10463 defaults, which we are not going to use. Hence we can remove
10464 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
10465 Don't warn if site-lisp directories are missing.
10466 If not installed, start from a blank load-path, since
10467 PATH_LOADSEARCH refers to the eventual installation directories.
10469 2012-07-07 Eli Zaretskii <eliz@gnu.org>
10471 Support truncation and continuation glyphs on GUI frames, when
10472 fringes are disabled. (Bug#11832)
10473 * xdisp.c (init_iterator): Get dimensions of truncation and
10474 continuation glyphs even if on GUI frames.
10475 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10476 or both, are absent.
10477 (start_display, move_it_in_display_line_to): Handle the case of a
10478 GUI frame without a fringe to display continuation or truncation
10480 (insert_left_trunc_glyphs): Support GUI frames: make sure
10481 truncation glyphs overwrite enough glyphs from the current line to
10482 have sufficient space in pixels.
10483 (display_line): Support truncation and continuation glyphs on GUI
10484 frames. If some spare pixels are left on the line after inserting
10485 the truncation glyphs, fill that space with a stretch glyph of a
10486 suitably computed width.
10488 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10489 produce_glyphs, to support GUI sessions.
10491 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10493 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10495 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10497 Do not require float-time's arg to fit in time_t (Bug#11825).
10498 This works better on hosts where time_t is unsigned, and where
10499 float-time is applied to the (negative) difference between two times.
10500 * editfns.c (decode_time_components): Last arg is now double *,
10501 not int *, and means to store all the result as a double, without
10502 worrying about whether the seconds part fits in time_t.
10503 All callers changed.
10504 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10505 All callers changed.
10506 (Ffloat_time): Do not fail merely because the specified time falls
10507 outside of time_t range.
10509 2012-07-07 Glenn Morris <rgm@gnu.org>
10511 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
10512 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
10513 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
10515 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
10517 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
10518 Update dependencies.

10528 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
10529 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
10531 * xfont.c (compare_font_names): Redo to omit the need for casts.
10533 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
10535 * xfns.c (Fx_change_window_property): Doc fix.
10536 * w32fns.c (Fx_change_window_property): Doc fix.
10538 * w32fns.c (Fx_window_property): Accept the same arguments as the
10539 X Windows version. Doc fix.
10540 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
10542 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10543 Eli Zaretskii <eliz@gnu.org>
10545 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10546 Windows-specific code from nt/config.nt moved here.
10547 Obsolete settings removed.
10549 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10551 * process.c: Avoid unnecessary calls to gettime.
10552 (wait_reading_process_output): Don't get the time of day
10553 when gobbling data immediately and not waiting, as there's no need
10554 for it in that case. This removes a FIXME.
10556 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10558 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10559 is defined (Bug#11768).
10561 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10563 Fix marker debugging code.
10564 * marker.c (byte_char_debug_check): Do not perform the check
10565 if buffer is not multibyte.
10566 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10567 Call byte_char_debug_check with correct arguments.
10569 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10571 Compile marker debugging code only if ENABLE_CHECKING is defined.
10572 * marker.c (byte_char_debug_check, count_markers):
10573 Use only if ENABLE_CHECKING is defined.
10574 (byte_debug_flag): Remove.
10575 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10576 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
10578 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10580 Avoid code repetition in marker-related functions.
10581 * marker.c (attach_marker): New function.
10582 (Fset_marker, set_marker_restricted, set_marker_both)

10585 Consistently rename charno to charpos.
10586 (marker_position): Add eassert.
10587 (marker_byte_position): Convert to eassert.

10603 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
10604 (save_restriction_save): Use build_marker.
10605 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
10606 * window.c (save_window_save): Likewise.
10608 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10610 Do not use Fdelete_overlay in delete_all_overlays
10611 to avoid redundant calls to unchain_overlay.
10612 * buffer.c (drop_overlay): New function.
10613 (delete_all_overlays, Fdelete_overlay): Use it.
10614 * minibuf.c (get_minibuffer): Fix comment.
10616 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10618 Port to OpenBSD 5.1 amd64.
10619 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10620 This is needed for OpenBSD, and should be harmless on all BSD systems.
10621 Also, include <sys/sysctl.h>, as it should be available on all
10622 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10623 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10624 use p_pid member, not kp_proc.pid.
10626 2012-07-06 Glenn Morris <rgm@gnu.org>
10628 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10630 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10632 More xmalloc and related cleanup.
10633 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

10641 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
10643 Omit needless casts involving void * pointers and allocation.
10644 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10645 as the former is more robust if P's type is changed.
10646 Prefer xzalloc to xmalloc + memset 0.
10647 Simplify malloc-or-realloc to realloc.
10648 Don't worry about xmalloc returning a null pointer.
10649 Prefer xstrdup to xmalloc + strcpy.
10650 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
10652 * keyboard.c (apply_modifiers_uncached): Prefer local array to
10653 alloca of a constant.

10657 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10658 hscroll is larger than the line width. Fixes long and futile
10659 looping inside extend_face_to_end_of_line (on a TTY) producing
10660 glyphs that are not needed and thrown away.
10662 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10664 * marker.c (set_marker_restricted_both): Simplify by using
10667 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

10678 followed by gtk_box_set_homogeneous (Bug#11768).
10679 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10680 (update_theme_scrollbar_width, xg_create_scroll_bar):
10681 Use gtk_scrollbar_new (Bug#11768).
10682 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
10683 (is_box_type): New function (Bug#11768).
10684 (xg_tool_item_stale_p): Call is_box_type.
10685 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10686 with default display (Bug#11768).
10688 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10690 * xdisp.c (window_hscroll_limited): New function.
10691 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10692 coordinates when window's hscroll is set to insanely large
10693 values. (Bug#11857)
10695 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
10697 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

10756 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10758 * fileio.c (time_error_value): Check the right error number.
10759 Problem reported by Troels Nielsen in
10760 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10762 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10764 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10765 This should be fixed in a better way; see Eli Zaretskii in
10766 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10767 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10769 * fileio.c (time_error_value): Rename from special_mtime.
10770 The old name's problems were noted by Eli Zaretskii in
10771 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10773 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10774 This variable's comment says Emacs needs at least one GDB-visible
10775 symbol of type enum pvec_type, to work around GDB problems.
10776 The symbol's value doesn't matter.
10778 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10779 that causes compilation to fail on pre-C99 compilers.
10781 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10783 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
10784 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
10786 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10788 * buffer.c (init_buffer_once): Fix initialization of
10789 headers for buffer_defaults and buffer_local_symbols.
10790 Reported by Juanma Barranquero <lekktu@gmail.com>.
10792 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
10794 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
10795 * lisp.h (enum pvec_type): Use fewer bits.
10796 (PSEUDOVECTOR_SIZE_BITS): New constant.

10802 * fns.c (internal_equal): Adapt code to extract pvectype.
10803 * emacs.c (gdb_pvec_type): Update type.
10804 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
10805 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
10806 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
10807 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10808 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10809 abusing vector->header.next.nbytes.
10810 (live_vector_p): Use PVEC_TYPE.
10811 (mark_object): Adapt code to extract pvectype. Use switch.
10813 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10815 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10816 Tighten new eassert a bit.
10818 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10820 Fix compilation with --enable-gcc-warnings and -O1
10821 optimization level.
10822 * doprnt.c (doprnt): Change type of tem to int, initialize
10823 to avoid compiler warning. Add eassert.
10824 * search.c (simple_search): Initialize match_byte to avoid
10825 compiler warning. Add eassert.
10827 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10829 Avoid weird behavior with large horizontal scrolls.
10830 Without this change, for example, large hscroll values would
10831 mess up Emacs's display on Fedora 15 x86, presumably due to
10832 overflows in int calculations in the display code.
10833 Also, if buffers had long lines, Emacs would freeze.
10834 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10835 (set_window_hscroll): New function, containing the old guts of
10836 Fset_window_hscroll. Return the clipped value.
10837 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10838 This avoids the need to check against PTRDIFF_MAX.
10840 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10842 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10844 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10846 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10848 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10849 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10850 since GCC 4.4.6 issues a bogus warning for them.
10852 Fix bugs in file timestamp newness comparisons.
10853 * fileio.c (Ffile_newer_than_file_p):
10854 * lread.c (Fload): Use full timestamp resolution of files,
10855 not just the 1-second resolution, so that files that are only
10856 slightly newer still count as newer.
10857 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10858 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10860 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10862 * fileio.c: Improve handling of file time marker. (Bug#11852)
10863 (special_mtime): New function.
10864 (Finsert_file_contents, Fverify_visited_file_modtime):
10865 Use it to set special mtime values consistently.
10867 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10869 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10870 marker for non-existing file. (Bug#11852)
10872 2012-07-03 Glenn Morris <rgm@gnu.org>
10874 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10875 and did not make it into globals.h).
10877 2012-07-03 Tom Tromey <tromey@redhat.com>
10879 * window.c (Fset_window_margins, Fset_window_fringes)
10880 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
10881 * textprop.c (Fprevious_property_change): No longer static.
10882 * syntax.c (Fsyntax_table_p): No longer static.
10883 * process.c (Fget_process, Fprocess_datagram_address): No longer

10906 * font.h: Remove EXFUNs.
10907 * dosfns.c (system_process_attributes): Remove EXFUN.
10908 * keymap.h: Remove EXFUNs.
10909 * lisp.h: Remove EXFUNs.
10910 * w32term.h: Remove EXFUNs.
10911 * window.h: Remove EXFUNs.
10912 * xsettings.h: Remove EXFUN.
10913 * xterm.h: Remove EXFUN.
10915 2012-07-03 Glenn Morris <rgm@gnu.org>
10917 * lisp.h (Frandom): Make it visible to C.
10918 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
10919 buffer for invisible buffers. (Bug#1229)
10921 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10923 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
10924 values which aren't power of 2.
10925 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10926 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
10929 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
10931 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
10933 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10935 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10937 * alloc.c (allocate_vector_block): Remove redundant
10938 calls to mallopt if DOUG_LEA_MALLOC is defined.
10939 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10940 avoid calls to mallopt if zero_vector is returned.
10942 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10944 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10945 is enabled, avoid dereferencing NULL current_sblock if
10948 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10950 Cleanup basic buffer management.
10951 * buffer.h (struct buffer): Change layout to use generic vector
10952 marking code. Fix some comments. Change type of 'clip_changed'
10953 to bitfield. Remove unused #ifndef old.
10954 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10955 (GET_OVERLAYS_AT): Fix indentation.
10956 (for_each_per_buffer_object_at): New macro.
10957 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
10958 (Fbuffer_local_variables): Use it.
10959 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.

10961 struct buffer. Fix comment.
10962 (mark_overlay): New function.
10963 (mark_buffer): Use it. Use mark_vectorlike to mark normal
10964 Lisp area of struct buffer.
10965 (mark_object): Use it. Adjust marking of misc objects
10966 and related comments.
10968 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10970 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10971 wrapper that is not needed because the wrapped code is a no-op (zero
10972 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10973 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10975 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10977 * alloc.c (mark_buffer): Simplify. Remove prototype.
10978 (mark_object): Add comment. Reorganize marking of vector-like
10979 objects. Use CHECK_LIVE for all vector-like objects except buffers
10980 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10981 Avoid redundant calls to mark_vectorlike for bool vectors.
10983 2012-06-30 Glenn Morris <rgm@gnu.org>
10985 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10987 * epaths.in (PATH_SITELOADSEARCH): New.
10988 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10989 This is rather than relying on --enable-locallisppath elements
10990 having "site-lisp" in their names. (Bug#10208#25, 11658)
10992 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10994 * w32proc.c (sys_select): Accept and ignore one more argument.
10996 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10998 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10999 (pselect) [!MS_DOS]: Redirect to sys_select.
11001 * sysdep.c: Don't include dos.h and dosfns.h.
11003 * process.c (sys_select):
11004 * msdos.c (sys_select): Accept one more argument and ignore it.
11006 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
11007 adapt data types and code to that.
11010 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
11011 which clashes with the gnulib function of the same name.
11013 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
11015 * font.c (font_style_to_value, font_style_symbolic)
11016 (font_prop_validate_style): Add type checks for values in
11019 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
11021 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
11024 2012-06-29 Eli Zaretskii <eliz@gnu.org>
11026 * xdisp.c (try_window_id): Undo last change.
11028 * w32.c (getwd): Adjust commentary about startup_dir.
11029 (init_environment): Always call sys_access, even in non-MSVC
11030 builds. Don't chdir to the directory of the Emacs executable.
11031 This undoes code from 1997 which was justified by the need to
11032 "avoid conflicts when removing and renaming directories". But its
11033 downside was that every relative file name was being interpreted
11034 relative to the directory of the Emacs executable, which can never
11035 be TRT. In particular, it broke sys_access when called with
11036 relative file names.
11037 (sys_access): Map GetLastError to errno.
11039 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11041 * window.h (struct window): Change type of 'fringes_outside_margins'
11042 to bitfield. Fix comment. Adjust users accordingly.
11043 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
11045 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
11048 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
11050 * gnutls.c (emacs_gnutls_handshake):
11051 Add QUIT to make the loop interruptible.
11053 2012-06-29 Glenn Morris <rgm@gnu.org>
11055 * charset.c (init_charset): Make lack of etc/charsets fatal.
11057 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

11063 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
11064 undefined. Convert from xassert to eassert.

11066 * nsterm.m: Likewise.
11068 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

11072 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
11074 Avoid integer overflow on scroll-left and scroll-right.
11075 * window.c (HSCROLL_MAX): New macro.
11076 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
11077 overflow when requested scroll falls outside ptrdiff_t range.
11079 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11081 * window.h (struct window): Change type of 'hscroll',
11082 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
11083 'last_modified' and 'last_overlay_modified' to EMACS_INT.
11084 Adjust users accordingly.
11085 * xdisp.c (try_cursor_movement): Replace type check with eassert.
11086 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
11087 from EMACS_INT to ptrdiff_t.
11088 (make_window): Omit redundant initialization.
11090 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

11107 Fix GLYPH_DEBUG usage assuming that it may be undefined,
11108 adjust comments accordingly.

11190 when building with Clang.

11229 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
11231 Use sprintf return value instead of invoking strlen on result.
11232 In the old days this wasn't portable, since some sprintf
11233 implementations returned char *. But they died out years ago and
11234 Emacs already assumes sprintf returns int.
11235 Similarly for float_to_string.
11236 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
11237 * ccl.c (ccl_driver):

11242 * xdisp.c (message_dolog):
11243 * xfns.c (syms_of_xfns):
11244 Use sprintf or float_to_string result to avoid need to call strlen.
11245 * data.c (Fnumber_to_string):
11246 Use make_unibyte_string, since the string must be ASCII.
11247 * lisp.h, print.c (float_to_string): Now returns int length.
11248 * term.c (produce_glyphless_glyph):
11249 Use sprintf result rather than recomputing it.
11251 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
11252 * Makefile.in (ALL_CFLAGS):
11253 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

11289 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
11290 instead of truncating it to 63 (admittedly a generous limit).
11292 * process.c: Fix spelling and caps in comments.
11294 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>

11345 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11347 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
11348 * lisp.h (WAIT_READING_MAX): New macro.
11349 * dispnew.c (Fsleep_for, sit_for):
11350 * keyboard.c (kbd_buffer_get_event):
11351 * process.c (Faccept_process_output):
11352 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
11353 This improves on the previous patch, which introduced a bug
11354 when time_t is unsigned and as wide as intmax_t.
11355 See <http://bugs.gnu.org/9000#51>.
11357 2012-06-23 Eli Zaretskii <eliz@gnu.org>

11386 language ID in the event parameters.
11388 * w32term.c (w32_read_socket): Put the new keyboard codepage into
11389 event.code, not the obscure "character set ID".
11391 2012-06-23 Chong Yidong <cyd@gnu.org>
11393 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

11420 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
11422 Support higher-resolution time stamps (Bug#9000).
11423 The time stamps are only nanosecond-resolution at the C level,
11424 since that's the best that any real-world system supports now.
11425 But they are picosecond-resolution at the Lisp level, as that's
11426 easy, and leaves room for future OS improvements.
11428 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
11431 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
11432 Don't get current time unless it's needed.
11434 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
11435 now provides it if it's absent.
11436 (start_atimer): Port to higher-res time stamps.
11437 Check for time stamp overflow. Don't get current time more
11438 often than is needed.
11440 * buffer.h (struct buffer): Buffer modtime now has high resolution.
11441 Include systime.h, not time.h.
11442 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
11444 * dired.c: Include stat-time.h.
11445 (Ffile-attributes): File times now have higher resolution.
11447 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
11448 (struct image): Timestamp now has higher resolution.
11450 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
11451 has at least microseconds now. All uses removed.
11452 (update_frame, update_single_window, update_window, update_frame_1)
11453 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
11454 (duration_to_sec_usec): Remove; no longer needed.
11456 * editfns.c (time_overflow): Now extern.
11457 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
11458 (float-time, Fformat_time_string, Fcurrent_time_string)

11462 (decode_time_components, lisp_seconds_argument): New functions.
11463 (make_time): Now static.
11464 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
11465 Report an error if the time is invalid, rather than having the caller
11468 * fileio.c: Include <stat-time.h>
11469 (Fcopy_file): Copy higher-resolution time stamps.
11470 Prefer to set the time stamp via a file descriptor if that works.
11471 (Fset_file_times, Finsert_file_contents, Fwrite_region)
11472 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
11473 (Fvisited_file_modtime, Fset_visited_file_modtime):
11474 Support higher-resolution time stamps.
11476 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
11478 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
11480 * image.c (prepare_image_for_display, clear_image_cache)
11481 (lookup_image): Port to higer-resolution time stamps.
11483 * keyboard.c (start_polling, bind_polling_period):
11484 Check for time stamp overflow.
11485 (read_char, kbd_buffer_get_event, timer_start_idle)
11486 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
11487 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
11488 Port to higher-resolution time stamps. Do not assume time_t is signed.
11489 (decode_timer): New function. Timers are now vectors of length 9,
11490 not 8, to accommodate the picosecond component.
11491 (timer_check_2): Use it.
11493 * nsterm.m (select_timeout, timeval_subtract): Remove.
11494 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
11495 as they're a bit more accurate and handle overflow better.
11496 (ns_select): Change prototype to be compatible with pselect.
11497 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11498 * nsterm.h (ns_select): Adjust prototype.
11500 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
11501 us-resolution time stamps.
11502 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
11504 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
11506 * lisp.h (time_overflow): New decl.
11507 (wait_reading_process_output): First arg is now intmax_t, not int,
11508 to accommodate larger waits.
11510 * process.h (struct Lisp_Process.read_output_delay):
11511 Now counts nanoseconds, not microseconds.
11512 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
11514 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
11515 (wait_reading_process_output):
11516 Port to ns-resolution time stamps.
11517 (Faccept_process_output, wait_reading_process_output):
11518 Check for time stamp overflow. Do not assume time_t is signed.
11519 (select_wrapper): Remove; we now use pselect.
11520 (Fprocess_attributes): Now generates ns-resolution time stamps.
11522 * sysdep.c: Include utimens.h. Don't include utime.h
11523 or worry about struct utimbuf; gnulib does that for us now.
11524 (gettimeofday): Remove; gnulib provides a substitute.
11525 (make_timeval): New function.
11526 (set_file_times): Now sets ns-resolution time stamps.
11527 New arg FD; all uses changed.
11528 (time_from_jiffies, ltime_from_jiffies, get_up_time)
11529 (system_process_attributes):
11530 Now returns ns-resolution time stamp. All uses changed.
11531 Check for time stamp overflow.
11533 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
11534 provides a substitute now.
11536 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11537 since it guarantees struct timespec.
11538 (EMACS_TIME): Now struct timespec, so that we can support
11539 ns-resolution time stamps.
11540 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11541 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11542 (EMACS_USECS): Remove.
11543 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11544 so multiply the arg by 1000 before storing it.
11545 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
11547 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
11548 Port to ns-resolution time stamps.
11549 (EMACS_TIME_NEG_P): Remove; replaced by....
11550 (EMACS_TIME_SIGN): New macro.

11552 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
11553 (set_file_times, make_time, lisp_time_argument): Adjust signature.
11554 (make_timeval, make_lisp_time, decode_time_components): New decls.
11555 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11556 that it mishandled time_t overflow. You can't compare by subtracting!
11557 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11558 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
11560 * term.c: Include <sys/time.h>.
11561 (timeval_to_Time): New function, for proper overflow wraparound.
11562 (term_mouse_position, term_mouse_click): Use it.
11564 * undo.c (record_first_change): Support higher-resolution time stamps
11565 in the undo buffer.
11566 (Fprimitive_undo): Use them when restoring time stamps.
11568 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
11569 (w32_get_internal_run_time):
11570 Port to higher-resolution Emacs time stamps.
11571 (ltime): Now accepts single 64-bit integer, as that's more convenient
11574 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
11576 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
11577 for compatibility with pselect. Support ns-resolution time stamps.
11579 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
11581 * xselect.c (wait_for_property_change, x_get_foreign_selection):
11582 Check for time stamp overflow, and support ns-resolution time stamps.
11584 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
11585 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
11586 (timeval_subtract): Remove; no longer needed.
11587 (XTflash, XTring_bell, x_wait_for_event):
11588 Port to ns-resolution time stamps. Don't assume time_t is signed.
11590 2012-06-22 Chong Yidong <cyd@gnu.org>

11594 2012-06-22 Eli Zaretskii <eliz@gnu.org>
11596 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
11597 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11598 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11599 staticidx goes up to 1597 out of 1600 = 0x640.)
11601 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11603 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
11604 Otherwise, the umask might be mistakenly 0 while handling input signals.
11606 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
11608 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

11615 access to `contents' member of Lisp_Vector objects with AREF and ASET
11618 2012-06-19 Chong Yidong <cyd@gnu.org>
11620 * frame.c (delete_frame): When selecting a frame on a different
11621 text terminal, do not alter the terminal's top-frame.
11623 * xdisp.c (format_mode_line_unwind_data): Record the target
11624 frame's selected window and its terminal's top-frame.
11625 (unwind_format_mode_line): Restore them.
11626 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
11628 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
11629 since tty frames can be explicitly named.
11630 (prepare_menu_bars): Likewise.
11632 * term.c (Ftty_top_frame): New function.
11634 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

11637 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
11638 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
11639 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
11640 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
11641 (METER_1, METER_2): Simplify.
11643 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
11645 * data.c (Fdefalias): Return `symbol' (bug#11686).
11647 2012-06-18 Martin Rudalics <rudalics@gmx.at>
11649 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11650 gets killed during executing of this function (Bug#11665).
11651 Try to always return Qt when the buffer has been actually killed.
11652 (Vkill_buffer_query_functions): In doc-string say that functions
11653 run by this hook should not change the current buffer.
11655 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11657 Fix recently-introduced process.c problems found by static checking.
11658 * process.c (write_queue_push, write_queue_pop, send_process):
11659 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
11660 (write_queue_pop): Fix pointer signedness problem.
11661 (send_process): Remove unused local.
11663 2012-06-17 Chong Yidong <cyd@gnu.org>

11675 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
11677 * lisp.h (eassert): Assume C89 or later.
11678 This removes the need for CHECK.
11679 (CHECK): Remove. Its comments about always evaluating its
11680 argument were confusing, as 'eassert' typically does not evaluate
11683 * coding.c (produce_chars): Use ptrdiff_t, not int.
11685 * xterm.c (x_draw_underwave): Check for integer overflow.
11686 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
11688 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
11690 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't
11691 referenced (Bug#11583).

11874 Use an inline function on all platforms when using the union type,
11875 since this is simpler and 'static inline' can be used portably

11982 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).

12019 * doprnt.c (doprnt): Truncate multibyte char correctly.
12020 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
12021 would mishandle a string argument "Xc" if X was a multibyte
12022 character of length 2: it would truncate after X's first byte
12023 rather than including all of X.
12025 2012-06-06 Chong Yidong <cyd@gnu.org>

12074 * minibuf.c (Fassoc_string): Remove duplicate declaration.
12076 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
12077 Convert pctcpu and pctmem to Lisp float properly.
12078 Let the compiler fold better, as 100.0/0x8000 is exact.

12082 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

12094 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
12095 change its type from Lisp_Object to bitfield.
12096 Change type of 'force_start', 'optional_new_start',
12097 'last_had_star', 'update_mode_line' and 'start_at_line_beg'

12104 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
12105 Use 'float' consistently, rather than 'float' in most places
12106 and 'double' in a couple of places.
12108 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12110 * xdisp.c (handle_stop): Detect whether we have overlay strings
12111 loaded by testing it->current.overlay_string_index to be
12112 non-negative, instead of checking whether n_overlay_strings is
12113 positive. (Bug#11587)
12115 2012-05-31 Chong Yidong <cyd@gnu.org>
12117 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

12123 * search.c (search_buffer): Remove calls to
12124 r_alloc_inhibit_buffer_relocation, as it is now called by

12130 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
12131 for the duration of call to load_charset, to avoid problems with
12132 callers of maybe_unify_char that access buffer text through C
12135 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
12136 decrement the inhibition flag, instead of just setting or

12141 Remove obsolete '#define static' cruft.
12142 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
12143 This #undef was "temporary" in 2000; it is no longer needed
12144 now that '#define static' has gone away.

12159 (safe_bcopy): Remove decl; no longer has that name.
12160 (main): Coalesce #if into single bit of code, for simplicity.

12176 * alloc.c, lisp.h (make_pure_vector): Now static.
12178 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
12180 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
12181 Move to byte-run.el.

12190 Do not create empty overlays with the evaporate property (Bug#9642).
12191 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
12192 Bug#9642, but explicitly check that the buffer the overlay would
12193 be moved to is live and rearrange lines to make sure that errors
12194 will not put the overlay in an inconsistent state.
12195 (Fdelete_overlay): Cosmetics.
12197 2012-05-28 Eli Zaretskii <eliz@gnu.org>
12199 * w32term.c (my_bring_window_to_top): New function.
12200 (x_raise_frame): Use handle returned by DeferWindowPos, which
12201 could be different from the original one.

12211 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
12213 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
12214 This avoids undefined behavior that might cause the eassert
12215 to not catch an out-of-range value.
12217 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
12219 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

12229 when referring to sectname field in printf format.
12231 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
12233 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
12234 Only r_alloc_inhibit_buffer_relocation needed to be added;
12235 the others were already declared.
12237 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
12238 before checking whether it's out of range. Put the check inside
12240 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
12242 2012-05-27 Ken Brown <kbrown@cornell.edu>
12244 * callproc.c (Fcall_process): Restore a line that was accidentally
12245 commented out in the 2011-02-13 change (bug#11547).
12247 2012-05-27 Eli Zaretskii <eliz@gnu.org>
12249 * lisp.h [REL_ALLOC]: Add prototypes for external functions
12250 defined on ralloc.c.
12252 * buffer.c [REL_ALLOC]: Remove prototypes of
12253 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
12254 they are now on lisp.h.
12256 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
12258 * search.c (search_buffer): Use it to inhibit relocation of buffer
12259 text while re_search_2 is doing its job, because re_search_2 is
12260 passed C pointers to buffer text. (Bug#11519)
12262 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
12263 Update value to 24.
12265 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
12266 state after an additional call to move_it_in_display_line_to, keep
12267 the values of it->max_ascent and it->max_descent found for the
12269 (pos_visible_p): Revert the comparison against bottom_y to what it
12270 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
12273 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12275 Fix coding-related core dumps with gcc -ftrapv.
12276 The code was computing A - B, where A and B are pointers, and B is
12277 random garbage. This can lead to core dumps on platforms that
12278 have special pointer registers, and it also leads to core dumps on
12279 x86-64 when compiled with gcc -ftrapv. The fix is to compute
12280 A - B only when B is initialized properly.
12281 * coding.c (coding_set_source, coding_set_destination): Return void.
12282 (coding_change_source, coding_change_destinations): New functions,
12283 with the old behaviors of coding_set_source and coding_set_destination.
12284 All callers that need an offset changed to use these new functions.
12286 2012-05-26 Glenn Morris <rgm@gnu.org>
12288 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
12290 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12292 Extend mouse support on W32 text-mode console.
12293 * xdisp.c (draw_row_with_mouse_face):
12294 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
12296 * w32console.c: Include window.h.
12297 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
12299 (initialize_w32_display): Initialize mouse-highlight data.
12301 * w32inevt.c: Include termchar.h and window.h.
12302 (do_mouse_event): Support mouse-autoselect-window. When the mouse
12303 moves, call note_mouse_highlight. If help_echo changed, call
12304 gen_help_event to produce help-echo message in the echo area.
12305 Call clear_mouse_face if mouse_face_hidden is set in the mouse
12308 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12310 * lread.c (read1): Simplify slightly to avoid an overflow warning
12311 with GCC 4.7.0 on x86-64.
12313 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12315 * bidi.c (bidi_mirror_char): Revert last change: an int is
12316 definitely wide enough here.
12318 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
12320 Fix integer width and related bugs (Bug#9874).

12332 Use int, not EMACS_INT, where int is wide enough.
12333 (inhibit_garbage_collection, Fgarbage_collect):
12334 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12335 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
12336 int might not be wide enough.

12352 (Foverlay_recenter, last_overlay_modification_hooks_used)
12353 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
12354 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12355 (validate_region): Omit unnecessary test for b <= e,
12356 since that's guaranteed by the previous test.
12357 (adjust_overlays_for_delete): Avoid pos + length overflow.
12358 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
12359 (report_overlay_modification):
12360 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12361 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
12362 Omit pointer cast, which isn't needed anyway, and doesn't work
12363 after the EMACS_INT -> ptrdiff_t change.
12364 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
12365 * buffer.h: Adjust decls to match defn changes elsewhere.
12366 (struct buffer_text, struct buffer):
12367 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12368 Use EMACS_INT, not int, where int might not be wide enough.
12369 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
12370 not int, to avoid needless 32-bit limit on 64-bit hosts.
12371 (exec_byte_code): Use tighter memory-full test, one that checks
12372 for alloca overflow. Don't compute the address of the object just
12373 before an array, as that's not portable. Use EMACS_INT, not
12374 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
12375 * callint.c (Fcall_interactively):
12376 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12377 * callproc.c (call_process_kill, Fcall_process):
12378 Don't assume pid_t fits into an Emacs fixnum.

12387 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
12388 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12389 (casify_object): Avoid integer overflow when overallocating buffer.
12390 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
12391 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
12392 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
12393 * category.h (CATEGORYP): Don't assume arg is nonnegative.
12394 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
12395 integers are now checked earlier. All uses replaced with XINT.
12397 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12398 For CCL_MapSingle, check that content and value are in int range.
12399 (ccl_driver, Fregister_code_conversion_map):
12400 Check that Vcode_version_map_vector is a vector.
12401 (resolve_symbol_ccl_program): Check that vector header is in range.
12402 Always copy the vector, so that we can check its contents reliably
12403 now rather than having to recheck each instruction as it's being
12404 executed. Check that vector words fit in 'int'.
12405 (ccl_get_compiled_code, Fregister_ccl_program)
12406 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
12407 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
12408 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
12409 contents are in range.
12410 (Fccl_execute_on_string): Check that status is in range.
12411 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
12412 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
12413 Accept and return EMACS_INT, not int, because callers can pass values
12414 out of 'int' range.

12420 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12421 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
12422 avoid mishandling large integers.

12429 Don't assume fixnum fits in int.
12430 (load_charset_map_from_vector, Fmap_charset_chars):
12431 Remove now-unnecessary CHECK_NATNUMs.
12432 (Fdefine_charset_internal): Check ranges here, more carefully.
12433 Don't rely on undefined behavior with signed left shift overflow.
12434 Don't assume unsigned int fits into fixnum, or that fixnum fits
12435 into unsigned int. Don't require max_code to be a valid fixnum;
12436 that's not true for gb10830 4-byte on a 32-bit host. Allow
12437 invalid_code to be a cons, for the same reason. Require code_offset
12438 to be a character. Avoid int overflow if max_char is close
12440 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
12441 this is intended anyway and avoids some undefined behavior.
12442 (load_charset_map): Pass unsigned, not int, as 2nd arg of
12443 INDEX_TO_CODE_POINT, as that's what it expects.
12444 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
12445 * charset.h (DECODE_CHAR): Return int, not unsigned;
12446 this is what was intended anyway, and it avoids undefined behavior.
12447 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
12448 integer-overflow issues.
12449 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
12450 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
12451 where the argument is EMACS_INT, and this behavior is not intended.
12452 * chartab.c (Fmake_char_table, Fset_char_table_range)
12453 (uniprop_get_decoder, uniprop_get_encoder):
12454 Don't assume fixnum fits in int.
12455 * cmds.c (move_point): New function, that does the gist of
12456 Fforward_char and Fbackward_char, but does so while checking
12457 for integer overflow more accurately.
12458 (Fforward_char, Fbackward_char): Use it.
12459 (Fforward_line, Fend_of_line, internal_self_insert)
12460 (internal_self_insert):
12461 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

12520 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
12521 Do not attempt to compute the address of the object just before a

13245 Put "libexec" before "bin", for the sake of init_callproc_1.
13247 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13249 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
13251 * unexaix.c: Port to more-recent AIX compilers.
13252 (report_error, report_error_1, make_hdr, copy_sym)
13253 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
13254 Make arguments const char *, not char *, to avoid violations of C
13255 standard and to fix some AIX warnings reported by Gilles Pion.
13257 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13259 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
13260 already have overlays loaded.
13261 (handle_single_display_spec): Before returning without displaying
13262 fringe bitmap, synchronize the bidi iterator with the main display
13263 iterator, by calling iterate_out_of_display_property.
13264 (iterate_out_of_display_property): Detect buffer iteration by
13265 testing that it->string is a Lisp string.
13266 (get_next_display_element): When the current object is exhausted,
13267 and there's something on it->stack, call set_iterator_to_next to
13268 proceed with what's on the stack, instead of returning zero.
13269 (set_iterator_to_next): If called at the end of a Lisp string,
13270 proceed to consider_string_end without incrementing string
13271 position. Don't increment display vector index past the end of
13272 the display vector. (Bug#11417)
13273 (pos_visible_p): Don't report a position visible when move_it_to
13274 stopped at the last line of window, which happens to be scanned
13275 backwards by the bidi iteration. (Bug#11464)
13277 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13279 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
13280 and right-margin display specs even if the spec is invalid or we
13281 are on a TTY, and thus unable to display on the fringes.
13282 That's because the text with the property will not be displayed anyway,
13283 so we need to signal to the caller that this is a "replacing"
13284 display spec. This fixes display when the spec is invalid or we
13287 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13289 * unexaix.c (make_hdr): Fix typo in prototype.
13290 This bug broke the build on AIX. Problem reported by Gilles Pion.
13292 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
13294 * keyboard.c (kbd_buffer_get_event): Read special events also in
13295 batch mode. (Bug#11415)
13297 2012-05-12 Glenn Morris <rgm@gnu.org>
13299 * ns.mk: Update for ns_appbindir no longer having trailing "/".
13301 2012-05-12 Eli Zaretskii <eliz@gnu.org>
13303 * lisp.mk (lisp): Add newcomment.elc.
13305 2012-05-12 Glenn Morris <rgm@gnu.org>
13307 * Makefile.in (MKDIR_P): New, set by configure.
13308 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
13310 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
13312 Remove unused function hourglass_started.
13313 * dispextern.h (hourglass_started):
13314 * w32fns.c (hourglass_started):
13315 * xdisp.c (hourglass_started): Remove.
13317 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
13319 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
13320 Update dependencies.
13322 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
13324 * xgselect.c (xg_select): Put maxfds+1 into a var.
13325 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
13327 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
13329 2012-05-10 Dave Abrahams <dave@boostpro.com>
13331 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
13332 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
13334 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
13336 * dbusbind.c (xd_registered_buses): New internal Lisp object.
13337 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
13338 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
13339 Initialize xd_registered_buses.
13341 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
13343 Untag more efficiently if USE_LSB_TAG.
13344 This is based on a proposal by YAMAMOTO Mitsuharu in
13345 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
13346 For an admittedly artificial (nth 8000 longlist) benchmark on
13347 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
13348 Emacs's overall text size by 1%.
13349 * lisp.h (XUNTAG): New macro.
13350 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
13351 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
13352 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
13353 * eval.c (Fautoload):
13354 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
13355 * frame.h (XFRAME): Use XUNTAG.
13357 Port recent dbusbind.c changes to 32-bit --with-wide-int.
13358 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
13359 Remove unportable assumptions about print widths of types like
13361 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
13362 intptr_t when converting between pointer and integer, to avoid GCC
13363 warnings about wrong width.
13365 2012-05-09 Eli Zaretskii <eliz@gnu.org>
13367 * w32proc.c (new_child): Force Windows to reserve only 64KB of
13368 stack for each reader_thread, instead of defaulting to 8MB
13369 determined by the linker. This avoids failures in creating
13370 subprocesses on Windows 7, see the discussion in this thread:
13371 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
13373 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
13375 Fix up display of the *Minibuf-0* buffer in the mini window.
13376 * keyboard.c (read_char): Don't clear the echo area if there's no
13378 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
13379 contents of *Minibuf-0*) if there's no message displayed in its stead.
13381 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
13383 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
13386 2012-05-06 Chong Yidong <cyd@gnu.org>
13388 * lisp.mk (lisp): Update.
13390 2012-05-05 Jim Meyering <meyering@redhat.com>
13392 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
13394 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
13396 * data.c (PUT_ERROR): New macro.
13397 (syms_of_data): Use it. Add new error type `user-error'.
13398 * undo.c (user_error): New function.
13399 (Fprimitive_undo): Use it.
13400 * print.c (print_error_message): Adjust print style for `user-error'.
13401 * keyboard.c (user_error): New function.
13402 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
13404 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
13406 Do not limit current-time-string to years 1000..9999.
13407 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
13408 (Fcurrent_time_string): Support any year that is supported by the
13409 underlying localtime representation. Don't use asctime, as it
13410 has undefined behavior for years outside the range -999..9999.
13412 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
13414 Fix race conditions involving setenv, gmtime, localtime, asctime.
13415 Without this fix, interrupts could mess up code that uses these
13416 nonreentrant functions, since setting TZ invalidates existing
13417 tm_zone or tzname values, and since most of these functions return
13418 pointers to static storage.
13419 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
13420 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
13421 Grow the critical sections to include not just invoking
13422 localtime/gmtime, but also accessing these functions' results
13423 including their tm_zone values if any, and any related TZ setting.
13424 (format_time_string): Last arg is now struct tm *, not struct tm **,
13425 so that the struct tm is saved in the critical section.
13426 All callers changed. Simplify allocation of initial buffer, partly
13427 motivated by the fact that memory allocation needs to be outside
13428 the critical section.
13430 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
13432 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
13433 with RESET_INTERVAL.
13435 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
13436 Remove duplicated buffer name initialization.
13438 2012-05-02 Jim Meyering <jim@meyering.net>
13440 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
13442 * xfns.c (x_window): Use xstrdup (Bug#11375).
13444 2012-05-02 Eli Zaretskii <eliz@gnu.org>
13446 * xdisp.c (pos_visible_p): If already at a newline from the
13447 display string before the 'while' loop, don't walk back the glyphs
13448 from it3.glyph_row. Solves assertion violation when the display
13449 string begins with a newline (egg.el). (Bug#11367)
13451 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
13453 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
13456 2012-05-01 Glenn Morris <rgm@gnu.org>
13458 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
13459 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
13460 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
13461 All were removed before 23.1.
13463 * dispnew.c: Remove HAVE_LIBNCURSES test;
13464 it is always true on relevant platforms.
13466 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
13467 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
13469 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
13471 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
13473 * .gdbinit (xpr): Remove checks for no longer existing misc types.
13474 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
13477 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
13479 Do not avoid creating empty evaporating overlays (Bug#9642).
13480 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13481 That is, do not delete an evaporating overlay if it becomes
13482 empty after its bounds are adjusted to fit within its buffer.
13483 This fix caused other problems, and I'm reverting it until we get
13484 to the bottom of them.
13486 2012-04-27 Chong Yidong <cyd@gnu.org>
13488 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
13490 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13492 * xdisp.c (pos_visible_p): If the window start position is beyond
13493 ZV, start the display from buffer beginning. Prevents assertion
13494 violation in init_iterator when the minibuffer window is scrolled
13495 via the scroll bar.
13497 * window.c (window_scroll_pixel_based): Likewise.
13499 2012-04-27 Chong Yidong <cyd@gnu.org>
13501 * keymap.c (where_is_internal): Doc fix (Bug#10872).
13503 2012-04-27 Glenn Morris <rgm@gnu.org>
13505 * fileio.c (Fcopy_file, Fset_file_selinux_context):
13506 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13508 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13510 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13511 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13513 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13515 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
13516 display element, check also the underlying string or buffer
13517 character. (Bug#11341)
13519 * w32menu.c: Include w32heap.h.
13520 (add_menu_item): If the call to AppendMenuW (via
13521 unicode_append_menu) fails, disable Unicode menus only if we are
13522 running on Windows 9X/Me.
13524 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13526 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13527 (xgetint): Add missing shift for LSB tags.
13529 2012-04-24 Martin Rudalics <rudalics@gmx.at>
13531 * keyboard.c (read_char): Don't wipe echo area for select window
13532 events: These might get delayed via `mouse-autoselect-window'
13535 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
13537 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
13538 manipulation of :loaded-from data.
13540 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
13542 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
13543 now a cons (bug#11311).
13545 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
13547 Do not create empty overlays with the evaporate property (Bug#9642).
13548 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13549 if it becomes empty after its bounds are adjusted to fit within
13550 its buffer. Without this fix, in a nonempty buffer (let ((o
13551 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13552 yields an empty overlay that has the evaporate property, which is
13553 not supposed to happen.
13555 Fix minor GTK3 problems found by static checking.
13556 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
13557 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13558 (struct _EmacsFixedClass, emacs_fixed_get_type):
13559 Move decls here from emacsgtkfixed.h, since they needn't be public.
13560 (emacs_fixed_get_type): Now static.
13561 (emacs_fixed_class_init): Omit unused local.
13562 (emacs_fixed_child_type): Remove; unused.
13563 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
13564 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13565 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
13566 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
13567 (EMACS_FIXED_GET_CLASS): Remove; unused.
13568 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
13570 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
13571 Problem reported by Juanma Barranquero for Windows -Wunused-function.
13573 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13575 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
13576 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13577 (__malloc_size_t, __malloc_ptrdiff_t):
13578 Remove. All uses removed, replaced by the definiens if needed,
13579 since we can assume C89 or better now.
13580 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

13588 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
13589 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
13590 Define using prototypes, not old style.
13591 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
13592 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
13593 (align): Don't assume that signed integer overflow wraps around.
13594 Omit unused local var.
13595 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
13596 (_free_internal_nolock, memalign, mallochook, reallochook):
13597 Omit no-longer-needed casts.
13598 (valloc): Use getpagesize, not __getpagesize.
13599 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
13600 (struct hdr): The 'magic' member is now size_t, not unsigned long.
13602 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
13604 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
13606 Move functions from C to Lisp. Make non-blocking method calls
13607 the default. Implement further D-Bus standard interfaces.
13609 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

13627 (xd_get_connection_address): Rename from xd_initialize.
13628 Return cached address.
13629 (xd_remove_watch): Do not unset $DBUS_SESSION_BUS_ADDRESS.

13634 (Fdbus_get_unique_name): Make stronger parameter check.
13635 (Fdbus_message_internal): New defun.

13637 (Fdbus_method_return_internal, Fdbus_method_error_internal)
13638 (Fdbus_send_signal, Fdbus_register_service)

13649 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13651 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
13652 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
13653 Do not assume ptrdiff_t is the same width as 'int'.
13655 * alloc.c: Handle unusual debugging option combinations.
13656 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
13657 since the two debugging options are incompatible.
13658 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
13660 (mem_init, mem_insert, mem_insert_fixup):
13661 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
13662 (NEED_MEM_INSERT): Remove; no longer needed.
13664 2012-04-22 Leo Liu <sdl.web@gmail.com>

13668 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13670 * sysdep.c [__FreeBSD__]: Minor cleanups.
13671 (list_system_processes, system_process_attributes) [__FreeBSD__]:
13672 Use Emacs indenting style more consistently. Avoid some casts.
13673 Use 'double' consistently rather than mixing 'float' and 'double'.
13675 2012-04-21 Eduard Wiebe <usenet@pusto.de>

13698 * process.c (wait_reading_process_output): If EIO occurs on a pty,
13699 set the status to "failed" and ensure that sentinel is run.
13701 2012-04-20 Glenn Morris <rgm@gnu.org>
13703 * process.c (Fset_process_inherit_coding_system_flag)
13704 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

13714 farther than the first row after the header line, if any.
13715 Don't consider the header-line row as "partially visible", even if
13716 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
13718 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

13728 (WARN_CFLAGS, WERROR_CFLAGS): New macros.
13729 (ALL_CFLAGS): Use new macros rather than old.
13730 * process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.

13732 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
13733 -Wunused-result, -Wunused-variable. This should go away once
13734 the Emacs and Gnulib regex code is merged.
13735 (xmalloc, xrealloc): Now static.
13737 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

13754 New extern decls, to avoid calling undeclared functions.
13755 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
13756 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
13757 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13758 (NEED_MEM_INSERT): New macro.
13759 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13760 Remove one incorrect comment and fix another.

13774 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
13775 Remove decls. This fixes an "It stinks!".
13777 * alloc.c (which_symbols): Fix alignment issue / type clash.
13779 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
13781 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
13782 (struct Lisp_Misc_Any): Likewise.
13783 (struct Lisp_Free): Likewise.
13784 * alloc.c (union aligned_Lisp_Symbol): Define.

13794 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
13795 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
13796 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
13797 * s/netbsd.h, s/sol2-6.h:
13798 Remove definition of GC_MARK_STACK, since the default now works.
13799 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
13800 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
13801 no longer the default.
13802 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
13804 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
13806 * lread.c (lisp_file_lexically_bound_p):
13807 Fix hang at ";-*-\n" (bug#11238).
13809 2012-04-14 Eli Zaretskii <eliz@gnu.org>
13811 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
13812 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

13823 2012-04-13 Reuben Thomas <rrt@sc3d.org>
13825 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
13827 2012-04-11 Daniel Colascione <dancol@dancol.org>
13829 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13830 against is gone. It's better to use vfork now so that when Cygwin
13831 gains a new, working vfork, we use it automatically (bug#10398).
13833 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
13835 * window.c (save_window_save): Obey window-point-insertion-type.

13851 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
13853 * w32.c (w32_delayed_load): Record the full path of the library
13854 being loaded (bug#10424).
13856 2012-04-09 Glenn Morris <rgm@gnu.org>
13858 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
13859 not just in the obarray, before snarfing them. (Bug#11036)

13862 Pass EMACS rather than BUILT_EMACS.
13864 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
13866 * process.c (make_process):
13867 * process.h: Add integer `gnutls_handshakes_tried' member to

13876 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
13877 attempts per process (connection).
13879 2012-04-09 Chong Yidong <cyd@gnu.org>
13881 * eval.c (Fuser_variable_p, user_variable_p_eh)
13882 (lisp_indirect_variable): Functions deleted.
13883 (Fdefvar): Caller changed.
13885 * callint.c (Finteractive, Fcall_interactively):
13886 * minibuf.c (Fread_variable): Callers changed.
13888 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13890 * xdisp.c (set_cursor_from_row): If the display string appears in
13891 the buffer at position that is closer to point than the position
13892 after the display string, display the cursor on the first glyph of
13893 the display string. Fixes cursor display when a 'display' text
13894 property immediately follows invisible text. (Bug#11094)
13896 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13898 composite.c: use 'double' consistently
13899 * composite.c (get_composition_id): Use 'double' consistently
13900 instead of converting 'float' to 'double' and vice versa; this is
13901 easier to understand and avoids a GCC warning.
13903 2012-04-09 Glenn Morris <rgm@gnu.org>
13905 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13906 preparation for dumping it with emacs. (Bug#4789)
13907 (leimdir): New variable.

13927 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
13928 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
13929 (mark_memory): Mark Lisp_Objects only if pointers might hide in
13930 objects, as mark_maybe_pointer will catch them otherwise.
13931 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
13932 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

13943 * makefile.w32-in (OBJ2): Add xml.$(O).
13944 (GLOBAL_SOURCES): Add xml.c.
13945 ($(BLD)/xml.$(O)): New dependency list.
13947 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
13948 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
13949 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
13950 [!WINDOWSNT]: New macros.
13951 (init_libxml2_functions, libxml2_loaded_p): New functions.
13952 (parse_region): Call fn_xmlCheckVersion instead of using the macro
13953 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
13954 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
13955 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13957 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13958 Call init_libxml2_functions before calling libxml2 functions.
13959 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13961 * emacs.c: Don't include libxml/parser.h.
13962 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
13963 xmlCleanupParser directly.
13965 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
13967 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13969 * indent.c (Fvertical_motion): If there is a display string at
13970 point, use it.vpos to compute how many lines to backtrack after
13971 move_it_to point. (Bug#11133)
13973 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13975 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13976 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13977 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13978 macros related to unification of CJK characters. For the details,
13979 see the discussion following the message here:
13980 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
13982 2012-04-04 Chong Yidong <cyd@gnu.org>
13984 * keyboard.c (Vdelayed_warnings_list): Doc fix.
13986 2012-04-01 Eli Zaretskii <eliz@gnu.org>
13988 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
13989 instead of alloca. (Bug#11138)
13991 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
13993 * w32menu.c (is_simple_dialog): Properly check lisp types.
13996 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13998 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13999 position we get to after a call to move_it_to fails the
14000 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
14001 only if we wind up in a string from display property. (Bug#11063)
14003 * window.c (Fdelete_other_windows_internal): Invalidate the row
14004 and column information about mouse highlight, so that redisplay
14005 restores it after reallocating the glyph matrices. (Bug#7464)
14007 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
14008 string comes from a `display' text property, use the buffer
14009 position of that property as if we actually saw that position in
14011 (move_it_by_lines): Remove the assertion that
14012 "it->current_x == 0 && it->hpos == 0" which can be legitimately
14013 violated when there's a before-string at the beginning of a line.
14016 2012-03-30 Eli Zaretskii <eliz@gnu.org>
14018 * xdisp.c (append_space_for_newline): If the default face was
14019 remapped, use the remapped face for the appended newline.
14020 (extend_face_to_end_of_line): Use the remapped default face for
14021 extending the face to the end of the line.
14022 (display_line): Call extend_face_to_end_of_line when the default
14023 face was remapped. (Bug#11068)

14045 * keyboard.c (Vselection_inhibit_update_commands): New variable.
14046 (command_loop_1): Use it; inhibit selection update for
14047 handle-select-window too (Bug#8996).

14051 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
14053 2012-03-25 Kenichi Handa <handa@m17n.org>
14055 * dispextern.h (struct glyph): Change the bit length of
14056 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
14058 2012-03-24 Eli Zaretskii <eliz@gnu.org>
14060 * s/ms-w32.h (tzname): Include time.h before redirecting to

14069 !SYNC_INPUT. (Bug#11080)
14071 2012-03-23 Eli Zaretskii <eliz@gnu.org>
14073 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
14074 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
14075 when fetching a multibyte character consumes more bytes than
14076 CHAR_BYTES returns, due to unification of CJK characters in
14077 string_char. (Bug#11073)
14079 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
14081 * process.c (wait_reading_process_output): Handle pty disconnect
14082 by refraining from sending oneself a SIGCHLD (bug#10933).
14084 2012-03-22 Chong Yidong <cyd@gnu.org>
14086 * dispextern.h (struct it): New member string_from_prefix_prop_p.
14088 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
14089 Mark string as coming from a prefix property.
14090 (handle_face_prop): Use default face for prefix strings (Bug#4281).
14091 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
14093 2012-03-21 Chong Yidong <cyd@gnu.org>
14095 * xfaces.c (Vface_remapping_alist): Doc fix.
14097 2012-03-20 Eli Zaretskii <eliz@gnu.org>

14111 it fit in a valid range (Bug#11003).
14113 2012-03-18 Eli Zaretskii <eliz@gnu.org>
14115 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
14116 that is not from display property, accept the row as a "cursor
14117 row" if one of the string's character has a non-nil `cursor'
14118 property. Fixes cursor positioning when there are newlines in
14119 overlay strings, e.g. in icomplete.el. (Bug#11035)
14121 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
14123 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
14125 2012-03-12 Chong Yidong <cyd@gnu.org>
14127 * eval.c (inhibit_lisp_code): Rename from
14128 inhibit_window_configuration_change_hook; move from window.c.
14130 * xfns.c (unwind_create_frame_1, Fx_create_frame):
14131 * window.c (run_window_configuration_change_hook)
14132 (syms_of_window): Callers changed.

14155 2012-03-03 Glenn Morris <rgm@gnu.org>
14157 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
14159 2012-03-02 Eli Zaretskii <eliz@gnu.org>

14162 position past the first glyph_row that ends at ZV. (Bug#10902)
14163 (redisplay_window, next_element_from_string): Fix typos in
14165 (redisplay_window): Pass to move_it_vertically the margin in
14166 pixels, not in screen lines.

14170 * buffer.c (buffer-list-update-hook): Doc fix.
14172 2012-02-29 Eli Zaretskii <eliz@gnu.org>
14174 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
14175 push_it before setting up the iterator for the first overlay
14176 string, even if we have an empty string loaded.
14177 (next_overlay_string): If there's an empty string on the iterator
14178 stack, pop the stack. (Bug#10903)
14180 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
14182 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
14183 Suggested by Stefan Monnier in
14184 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
14185 * alloc.c (widen_to_Lisp_Object): New static function.
14186 (mark_memory): Also mark Lisp_Objects by fetching pointer words
14187 and widening them to Lisp_Objects. This would work even if
14188 USE_LSB_TAG is defined and wide integers are used, which might
14189 happen in a future version of Emacs.
14191 2012-02-25 Chong Yidong <cyd@gnu.org>
14193 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

14198 before saving to clipboard manager.
14200 2012-02-24 Chong Yidong <cyd@gnu.org>
14202 * keyboard.c (process_special_events): Handle all X selection
14203 requests in kbd_buffer, not just the next one (Bug#8869).
14205 2012-02-23 Chong Yidong <cyd@gnu.org>
14207 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
14208 call when setting menu-bar-lines and tool-bar-lines parameters.
14209 (unwind_create_frame_1): New helper function.
14211 * window.c (inhibit_window_configuration_change_hook): New var.

14230 when computing $valmask.
14232 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
14233 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
14234 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
14235 It's useless in that case, and it can cause problems on hosts
14236 that allocate halves of EMACS_INT values separately.
14237 Reported by Dan Horák. Diagnosed by Andreas Schwab in
14238 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
14239 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
14240 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
14241 it avoids undefined behavior on hosts where shifting right by more
14242 than the word width has undefined behavior.
14244 2012-02-19 Chong Yidong <cyd@gnu.org>
14246 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
14247 (Funhandled_file_name_directory, Ffile_name_as_directory)
14248 (Fdirectory_file_name, Fexpand_file_name)
14249 (Fsubstitute_in_file_name): Protect against invalid file handler
14250 return values (Bug#10845).

14264 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
14266 2012-02-15 Chong Yidong <cyd@gnu.org>
14268 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
14269 marked as special. Also, starting docstrings with * is obsolete.

14284 2012-02-12 Chong Yidong <cyd@gnu.org>
14286 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
14287 as that creates a dangerous corner case.
14289 * window.c (Fdelete_window_internal): Invalidate the mouse
14290 highlight (Bug#9904).
14292 2012-02-12 Glenn Morris <rgm@gnu.org>

14322 2012-02-07 Chong Yidong <cyd@gnu.org>
14324 * buffer.c (Fbuffer_local_variables)
14325 (buffer_lisp_local_variables): Handle unbound vars correctly;
14326 don't let Qunbound leak into Lisp.
14328 2012-02-07 Glenn Morris <rgm@gnu.org>
14330 * image.c (Fimagemagick_types): Doc fix.
14332 * image.c (imagemagick-render-type): Change it from a lisp object
14333 to an integer. Move the doc here from the lisp manual.

14363 before BEGV. (Bug#10696)
14365 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
14367 Handle overflow when computing char display width (Bug#9496).
14368 * character.c (char_width): Return EMACS_INT, not int.
14369 (char_width, c_string_width): Check for overflow when
14370 computing the width; this is possible now that individual
14371 characters can have unbounded width. Problem introduced
14372 by merge from Emacs 23 on 2012-01-19.

14396 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
14398 (x_produce_glyphs): If the component of a composition is a null

14403 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
14404 first 2 arguments are identical. This makes inserting large
14405 output from a subprocess an order of magnitude faster on
14406 MS-Windows, where all sbrk'ed memory is always contiguous.
14408 2012-01-31 Glenn Morris <rgm@gnu.org>

14506 DISP_STRING, and accept any glyph in a row whose object is that
14507 string as eligible for mouse highlight. Fixes mouse highlight of
14508 display strings from overlays. (Bug#10464)
14510 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
14512 emacs: fix an auto-save permissions race condition (Bug#10400)

14859 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
14860 verifies glyph row's hash code--we have just reallocated the

15025 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
15026 is set, removing the need for VIRT_ADDRESS_VARIES.
15027 (PURE_P): Use a more-efficient implementation that needs just one

15042 (erase_phys_cursor, update_window_cursor, show_mouse_face)
15043 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
15044 behave as if the cursor position were at the window margin.
15046 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
15047 and the cursor position is out of bounds, behave as if the cursor
15048 position were at the window margin. (Bug#10075)
15050 2011-11-18 Chong Yidong <cyd@gnu.org>
15052 * window.c (Fwindow_combination_limit): Make first argument

15074 compute_line_metrics.
15075 (compute_line_metrics): Call row_hash, instead of computing the
15078 * dispnew.c (verify_row_hash): Call row_hash for computing the
15079 hash code of a row, instead of duplicating code from xdisp.c.
15081 * dispextern.h (row_hash): Add prototype.
15083 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
15085 * frame.c (delete_frame): Don't delete the terminal when the last

15268 Otherwise, these inline functions do not conform to C99 and
15269 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
15270 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
15271 * intervals.c (adjust_intervals_for_insertion)

15274 (static_offset_intervals): Remove.
15275 (offset_intervals): Rewrite using the old contents of
15276 static_offset_intervals. The old version didn't conform to C99
15277 because an extern inline function contained a reference to an
15278 identifier with static linkage.

15543 (Fgnutls_deinit, Fgnutls_boot): Use it.
15545 * process.c (make_process): Initialize GnuTLS credentials to NULL.
15546 (deactivate_process): Call emacs_gnutls_deinit.
15548 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
15550 * image.c (x_create_x_image_and_pixmap):
15551 * w32.c (sys_rename, w32_delayed_load):
15552 * w32font.c (fill_in_logfont):
15553 * w32reg.c (x_get_string_resource): Silence compiler warnings.
15555 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
15557 * w32fns.c (w32_default_color_map): New function,
15558 extracted from Fw32_default_color_map.
15559 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
15561 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
15563 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
15565 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
15567 * keyboard.c (test_undefined): New function (bug#9751).
15568 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
15570 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
15572 * sysdep.c (init_sys_modes): Fix the check for the controlling
15573 terminal (Bug#6649).
15575 2011-10-20 Eli Zaretskii <eliz@gnu.org>
15577 * dispextern.h (struct bidi_it): New member next_en_type.
15579 * bidi.c (bidi_line_init): Initialize the next_en_type member.
15580 (bidi_resolve_explicit_1): When next_en_pos is valid for the
15581 current character, check also for next_en_type being WEAK_EN.
15582 (bidi_resolve_weak): Don't enter the expensive loop if the current
15583 position is before next_en_pos. Record the bidi type of the first
15584 non-ET, non-BN character we find, in addition to its position.
15585 (bidi_level_of_next_char): Invalidate next_en_type when
15586 next_en_pos is over-stepped.
15588 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
15590 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15591 * editfns.c: Rewrite current-time-zone so that it invokes
15592 the equivalent of (format-time-string "%Z") to get the time zone name.
15593 This fixes a bug when the time zone name contains characters that
15594 need converting from the system time locale to Emacs internal format.
15595 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15596 that patch fixed format-time-string to do the conversion, but
15597 I forgot to fix current-time-zone.
15598 (format_time_string): New function, containing most of
15599 what Fformat_time_string used to contain.
15600 (Fformat_time_string): Rewrite in terms of format_time_string.
15601 This doesn't change this function's behavior.
15602 (current-time-zone): Rewrite to use format_time_string.
15603 This fixes the bug reported by Michael Schierl in
15604 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15605 Jason Rumney's 2007-06-07 change worked around this bug, but
15607 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15609 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15611 * xdisp.c (start_display): If the character at POS is displayed
15612 via a display vector, reset IT->current.dpvec_index to zero.
15613 (try_window_reusing_current_matrix): If a line ends in a display
15614 vector or the next line starts in a display vector, continue
15615 redrawing the window even though the character position of
15616 start_row was reached.
15619 2011-10-18 Chong Yidong <cyd@gnu.org>
15621 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15622 with nobreak-char-display too.
15624 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15626 Fix part 3 of bug#9771.
15627 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15628 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15629 non-neutral characters if the current character is a paragraph
15630 separator (a.k.a. Newline). This avoids running the same
15631 expensive loop twice, once when we consume the preceding newline
15632 and the other time when the line actually needs to be displayed.
15633 Avoid the loop when we see neutrals on the base embedding level
15634 following a character whose directionality is the same as the
15635 paragraph's. This avoids running the expensive loop when a line
15636 ends in a long sequence of neutrals, like control characters.
15637 Add assertion against STRONG_AL type. Slightly rearrange code
15638 that determines the type of a neutral given the first non-neutral
15640 (bidi_level_of_next_char): Set next_en_pos to zero when
15641 invalidating its info.
15643 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15645 * xdisp.c (push_display_prop): Determine whether to record string
15646 or buffer position by IT->string, not by IT->method. Allow
15647 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15648 (move_it_vertically_backward): Don't look for character position
15649 immediately after the newline when in a continuation line.
15652 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15654 * window.c (coordinates_in_window): Rewrite and delabelize
15655 vertical border check. (Bug#5357) (Bug#9618)
15657 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
15659 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15660 errors in XSetWindowBorder (bug#9310).
15662 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15664 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15665 avoid crash when xmalloc overrun checking is enabled.
15667 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15669 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15670 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15671 cursor motion with <left> and <right> arrow keys.
15673 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15674 some callers set that themselves.
15676 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15678 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15679 display string and the previous row comes from the same string and
15680 is empty. (Bug#9739) (Bug#9738)
15682 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15684 * doc.c (get_doc_string): Encode file name (bug#9735).
15686 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15688 * bidi.c (bidi_level_of_next_char):
15689 * xdisp.c (get_visually_first_element): Remove old incorrect
15690 comments regarding the Unicode Line Separator character.
15692 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15694 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15696 * alloc.c (Fgc_status): Do not access beyond zombies array
15697 boundary if nzombies > MAX_ZOMBIES.
15698 * alloc.c (dump_zombies): Add missing format specifier.
15700 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15702 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15703 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15705 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15706 Some packages use them to denote characters with modifiers.
15708 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15710 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15711 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15712 matching a pp-number. Rename parameter var to var1.
15714 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15716 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15718 2011-10-08 Glenn Morris <rgm@gnu.org>
15720 * callint.c (Fcall_interactively): Give a more explicit error for the
15721 'c' case with a non-character input. (Bug#8479)
15723 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15725 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15727 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15728 lines that are hscrolled on the left.
15730 * dispnew.c (buffer_posn_from_coords): Account for a possible
15731 presence of header-line. (Bug#4426)
15733 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15735 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15736 Don't advertise functionality which we discourage or doesn't work.
15738 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15740 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15741 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15742 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15743 this makes Emacs dump core during garbage collection on rare
15744 occasions. sizeof is obviously inferior to offsetof here, so
15745 stick with offsetof.
15746 (GC_POINTER_ALIGNMENT): New macro.
15747 (mark_memory): Omit 3rd (offset) arg; caller changed.
15748 Don't assume EMACS_INT alignment is the same as pointer alignment.
15750 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15752 * keyboard.c (read_key_sequence_remapped): New var.
15753 (read_key_sequence): Compute remapping in the right buffer.
15754 (command_loop_1): Use read_key_sequence's remapping directly.
15756 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15758 * dired.c (file_name_completion): Don't expand file name.
15759 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15760 before checking file name handler.
15762 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15763 they've been requested explicitly (bug#9591).
15765 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15767 * keymap.c (Fsingle_key_description): Use make_specified_string
15768 instead of build_string to build string from push_key_description.
15771 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15773 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15774 This fixes a Y2038 bug on 64-bit hosts.
15775 * buffer.c (reset_buffer):
15776 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15777 (Fclear_buffer_auto_save_failure):
15778 Use 0, not -1, to represent an unset failure time, since time_t
15779 might not be signed.
15781 Remove dependency on glibc malloc internals.
15782 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15783 Move back here from lisp.h, but with their new implementations.
15784 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15785 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15786 * charset.c (charset_table_init): New static var.
15787 (syms_of_charset): Use it instead of xmalloc. This removes a
15788 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15789 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15790 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15791 Move back to alloc.c.
15792 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15793 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15795 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15797 * nsterm.m (windowDidResize): Call x_set_window_size only when
15798 ns_in_resize is true. Otherwise set pixelwidth/height and
15799 call change_frame_size (Bug#9628).
15801 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15803 Port --enable-checking=all to Fedora 14 x86-64.
15804 * charset.c (syms_of_charset): Also account for glibc malloc's
15805 internal overhead when calculating the initial malloc maximum.
15807 Port --enable-checking=all to Fedora 14 x86.
15808 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15810 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15811 (overrun_check_realloc, overrun_check_free):
15812 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15813 That way, xmalloc returns a properly-aligned pointer even if
15814 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15815 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15816 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15817 into account when calculating the initial malloc maximum.
15818 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15819 Move here from alloc.c, so that charset.c can use it too.
15820 Properly align; the old code wasn't right for common 32-bit hosts
15821 when configured with --enable-checking=all.
15822 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15823 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15825 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15827 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15830 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15832 * xdisp.c (compute_display_string_end): If there's no display
15833 string at CHARPOS, return -1.
15835 * bidi.c (bidi_fetch_char): When compute_display_string_end
15836 returns a negative value, treat the character as a normal
15837 character not covered by a display string. (Bug#9624)
15839 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15841 * lread.c (Fread_from_string): Fix typo in docstring.
15843 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15845 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15846 newline, reseat the iterator instead of bidi-iterating there one
15847 character at a time. (Bug#9610)
15848 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15849 TO_CHARPOS if the bidi iterator is at base embedding level.
15851 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15853 * lread.c (readevalloop): Use correct code for NBSP.
15854 (read1): Likewise. (Bug#9608)
15856 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15858 * dbusbind.c (Fdbus_register_signal): When service is not
15859 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15861 2011-09-25 Glenn Morris <rgm@gnu.org>
15863 * buffer.c (truncate-lines): Doc fix.
15865 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15867 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15868 (Fset_window_next_buffers): Doc fix.
15870 2011-09-24 Glenn Morris <rgm@gnu.org>
15872 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15874 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15876 Fix minor problems found by static checking.
15877 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
15878 * indent.c (Fvertical_motion): Fix == vs = typo.
15880 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15882 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15883 Default value is now t. Doc fix.
15885 * indent.c (Fvertical_motion): Compute and apply the overshoot
15886 logic when moving up, not only when moving down. Fix the
15887 confusing name and values of the it_overshoot_expected variable;
15888 logic changes accordingly. (Bug#9254) (Bug#9549)
15890 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15891 CHARPOS is covered by a display string which includes newlines.
15892 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15893 is covered by a display string with embedded newlines.
15895 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15897 * dbusbind.c (Fdbus_register_signal): Add match rule to
15898 Vdbus_registered_objects_table. (Bug#9581)
15899 (Fdbus_register_method, Vdbus_registered_objects_table):
15902 2011-09-24 Jim Meyering <meyering@redhat.com>
15904 do not ignore write error for any output size
15905 The previous change was incomplete.
15906 While it makes emacs --batch detect the vast majority of stdout
15907 write failures, errors were still ignored whenever the output size is
15908 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15909 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15910 && echo FAIL: ignored write error
15911 FAIL: ignored write error
15912 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15913 && echo FAIL: ignored write error
15914 FAIL: ignored write error
15915 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15917 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15919 * emacs.c (Fkill_emacs): In noninteractive mode exit
15920 non-successfully if a write error occurred on stdout. (Bug#9574)
15922 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15924 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15927 * dispextern.h (struct it): Update the comment documenting what
15930 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15932 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15933 a display string, extend search for cursor position to end of row.
15934 (find_row_edges): If the row ends in a newline from a display
15935 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15936 Handle the case of a display string with multiple newlines.
15937 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15938 non-empty line. Fixes confusing cursor motion with arrow keys at
15939 the beginning of a line that starts with whitespace.
15941 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15943 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15946 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15948 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15949 boolean (Bug#9154).
15951 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15953 * xdisp.c (display_line): Record maximum and minimum buffer
15954 positions even if no glyphs were produced (e.g., by a zero-width
15955 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15956 buffer positions that will be removed from the glyph row because
15958 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15959 column is beyond frame width: don't subtract 1 "pixel" when
15960 computing width of the stretch.
15961 (reseat_at_next_visible_line_start): Undo the change made on
15962 2011-09-17 that saved paragraph information and restored it after
15963 the call to `reseat'. (Bug#9545)
15965 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15967 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15968 and turn window cursor on if cleared (Bug#9415).
15970 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15972 * search.c (boyer_moore): Take unibyte characters from pattern
15973 literally. (Bug#9458)
15975 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15977 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
15979 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
15981 Fix minor problem found by static checking.
15982 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
15983 initialized, to pacify gcc -Wuninitialized.
15985 * fileio.c: Report proper errno when syscall falls.
15986 (Finsert_file_contents): Save and restore errno,
15987 so that report_file_error outputs the correct diagnostic.
15988 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15990 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15992 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15994 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15996 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15997 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
15999 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16001 * xdisp.c (reseat_at_next_visible_line_start): Keep information
16002 about the current paragraph and restore it after the call to reseat.
16004 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
16005 (bidi_find_paragraph_start): Search back for paragraph beginning
16006 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
16007 (bidi_move_to_visually_next): Only trigger paragraph-related
16008 computations when the last character is a newline or at EOB, not
16009 just any NEUTRAL_B. (Bug#9470)
16011 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
16012 truncated lines if point is covered by a display string. (Bug#9524)
16014 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
16016 * xselect.c: Relax test for outgoing X longs (Bug#9498).
16017 (cons_to_x_long): New function.
16018 (lisp_data_to_selection_data): Use it. Correct the test for
16019 short-versus-long data; it was negated. Break out of vector
16020 loop, for efficiency, when a long datum is discovered.
16022 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
16024 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
16026 2011-09-16 Eli Zaretskii <eliz@gnu.org>
16028 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
16029 GCC PR/17406) by declaring this function with external scope.
16031 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16033 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
16034 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
16036 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
16038 * editfns.c (Fformat): Correctly handle text properties on "%%".
16040 2011-09-15 Eli Zaretskii <eliz@gnu.org>
16042 * xterm.c (x_draw_composite_glyph_string_foreground):
16043 * w32term.c (x_draw_composite_glyph_string_foreground):
16044 * term.c (encode_terminal_code):
16045 * composite.c (composition_update_it, get_composition_id):
16046 * xdisp.c (get_next_display_element)
16047 (fill_composite_glyph_string): Add comments about special meaning
16048 of TAB characters in a composition.
16050 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16052 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
16053 This occurs when processing a multibyte format.
16054 Problem reported by Wolfgang Jenker.
16056 2011-09-15 Johan Bockgård <bojohan@gnu.org>
16058 * xdisp.c (try_cursor_movement): Only check for exact match if
16059 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
16061 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16063 Remove unused external symbols.
16064 * dispextern.h (calc_pixel_width_or_height): Remove decl.
16065 * xdisp.c (calc_pixel_width_or_height): Now static.
16066 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
16067 * indent.c (check_display_width):
16068 * w32term.c: Fix comment to match code.
16069 * xterm.c, xterm.h (x_catching_errors): Remove.
16071 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16073 * xselect.c: Use signed conversions more consistently (Bug#9498).
16074 (selection_data_to_lisp_data): Assume incoming selection data are
16075 signed integers, not unsigned. This is to be consistent with
16076 outgoing selection data, which was modified to use signed integers
16077 in as part of the fix to Bug#9196 in response to Jan D.'s comment
16078 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
16079 expects long, not unsigned long.
16081 2011-09-14 Eli Zaretskii <eliz@gnu.org>
16083 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
16084 computation of loop end. Reported by Johan Bockgård
16087 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
16089 * frame.c (Fother_visible_frames_p): Function deleted.
16091 2011-09-12 Eli Zaretskii <eliz@gnu.org>
16093 * indent.c (compute_motion): Process display vector front to back
16094 rather than the other way around. (Bug#2496)
16096 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
16098 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
16100 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
16102 * minibuf.c (Fread_from_minibuffer): Doc fix.
16104 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16106 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
16107 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
16109 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
16111 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
16112 value for non-existent files.
16114 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16116 * fileio.c (Finsert_file_contents): If the file cannot be opened,
16117 set its "size" to -1. This will set the modtime_size field of
16118 the corresponding buffer to -1, which is what
16119 verify-visited-file-modtime expects for files that do not exist.
16122 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
16124 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
16126 * lisp.h: ... from here. push_key_description is no longer
16127 defined in keyboard.c, so its declaration should not be in
16128 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
16129 logically belongs with push_key_description.
16131 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
16133 * buffer.h: Include <sys/types.h> instead of <time.h>.
16134 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
16135 Problem reported by Herbert J. Skuhra.
16137 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
16139 * xml.c (parse_region): Make the parsing work for
16140 non-comment-starting XML files again (bug#9144).
16142 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
16144 * image.c (gif_load): Fix calculation of bottom and right corner.
16147 2011-09-10 Eli Zaretskii <eliz@gnu.org>
16149 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
16150 redisplay in small windows.
16152 2011-09-09 Eli Zaretskii <eliz@gnu.org>
16154 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
16156 2011-09-08 Martin Rudalics <rudalics@gmx.at>
16158 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
16159 Operate on live windows only.
16161 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
16163 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
16165 2011-09-07 Eli Zaretskii <eliz@gnu.org>
16167 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
16168 only under bidi iteration.
16170 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
16172 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
16174 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16176 isnan: Fix porting problem to Solaris 10 with bundled gcc.
16177 Without this fix, the command to link temacs failed due to an
16178 undefined symbol __builtin_isnan. This is because
16179 /usr/include/iso/math_c99.h #defines isnan(x) to
16180 __builtin_isnan(x), but the bundled gcc, which identifies itself
16181 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
16183 * floatfns.c (isnan): #undef, and then #define to a clone of
16185 (Fisnan): Always define, since it's always available now.
16186 (syms_of_floatfns): Always define isnan at the Lisp level.
16188 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16190 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
16192 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16194 * fileio.c: Fix bugs with large file offsets (Bug#9428).
16195 The previous code assumed that file offsets (off_t values) fit in
16196 EMACS_INT variables, which is not true on typical 32-bit hosts.
16197 The code messed up by falsely reporting buffer overflow in cases
16198 such as (insert-file-contents "big" nil 1 2) into an empty buffer
16199 when "big" contains more than 2**29 bytes, even though this
16200 inserts just one byte and does not overflow the buffer.
16201 (Finsert_file_contents): Store file offsets as off_t
16202 values, not as EMACS_INT values. Check for overflow when
16203 converting between EMACS_INT and off_t. When checking for
16204 buffer overflow or for overlap, take the offsets into account.
16205 Don't use EMACS_INT for small values where int suffices.
16206 When checking for overlap, fix a typo: ZV was used where
16207 ZV_BYTE was intended.
16208 (Fwrite_region): Don't assume off_t fits into 'long'.
16209 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
16211 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
16213 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
16215 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16217 sprintf-related integer and memory overflow issues (Bug#9412).
16219 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
16220 (esprintf, exprintf, evxprintf): New functions.
16221 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
16222 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
16223 (modify_event_symbol): Do not assume that the length of
16224 name_alist_or_stem is safe to alloca and fits in int.
16225 (Fexecute_extended_command): Likewise for function name and binding.
16226 (Frecursion_depth): Wrap around reliably on integer overflow.
16227 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
16228 since some callers pass EMACS_INT values.
16229 (Fsingle_key_description): Don't crash if symbol name contains more
16230 than MAX_ALLOCA bytes.
16231 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
16232 (get_minibuffer): Arg is now EMACS_INT, not int.
16233 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
16234 (esprintf, exprintf, evxprintf): New decls.
16235 * window.h (command_loop_level, minibuf_level): Reflect API changes.
16237 * dbusbind.c (signature_cat): New function.
16238 (xd_signature, Fdbus_register_signal):
16239 Do not overrun buffer; instead, report string overflow.
16241 * dispnew.c (add_window_display_history): Don't overrun buffer.
16242 Truncate instead; this is OK since it's just a log.
16244 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
16245 even if the time zone offset is outlandishly large.
16246 Don't mishandle offset == INT_MIN.
16248 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
16249 when creating daemon; the previous buffer-overflow check was incorrect.
16251 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
16252 which has the guts of the old verror function.
16254 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
16255 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
16257 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
16258 (font_unparse_xlfd): Don't blindly alloca long strings.
16259 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
16260 fits in int, when using sprintf. Use single snprintf to count
16261 length of string rather than counting it via multiple sprintfs;
16262 that's simpler and more reliable.
16263 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
16264 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
16265 sprintf, in case result does not fit in int.
16267 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
16268 (fontset_from_font): Print it.
16270 * frame.c (tty_frame_count): Now printmax_t, not int.
16271 (make_terminal_frame, set_term_frame_name): Print it.
16272 (x_report_frame_params): In X, window IDs are unsigned long,
16273 not signed long, so print them as unsigned.
16274 (validate_x_resource_name): Check for implausibly long names,
16275 and don't assume name length fits in 'int'.
16276 (x_get_resource_string): Don't blindly alloca invocation name;
16277 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
16280 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
16281 (xg_check_special_colors, xg_set_geometry):
16282 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
16284 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
16285 Use esprintf, not sprintf, in case result does not fit in int.
16287 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16288 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
16289 it as a large positive number.
16290 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
16291 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16293 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
16294 in case result does not fit in int.
16296 * print.c (float_to_string): Detect width overflow more reliably.
16297 (print_object): Make sprintf buffer a bit bigger, to avoid potential
16298 buffer overrun. Don't assume list length fits in 'int'. Treat
16299 print length of 0 as 0, not as infinity; to be consistent with other
16300 uses of print length in this function. Don't overflow print length
16301 index. Don't assume hash table size fits in 'long', or that
16302 vectorlike size fits in 'unsigned long'.
16304 * process.c (make_process): Use printmax_t, not int, to format
16305 process-name gensyms.
16307 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
16309 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
16310 to avoid potential buffer overrun.
16312 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
16313 if X resource line is longer than 512 bytes.
16315 * xfns.c (x_window): Make sprintf buffer a bit bigger
16316 to avoid potential buffer overrun.
16318 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
16320 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
16322 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16324 Integer overflow fixes for scrolling, etc.
16325 Without these, Emacs silently mishandles large integers sometimes.
16326 For example, "C-u 4294967297 M-x recenter" was treated as if
16327 it were "C-u 1 M-x recenter" on a typical 64-bit host.
16329 * xdisp.c (try_window_id): Check Emacs fixnum range before
16330 converting to 'int'.
16332 * window.c (window_scroll_line_based, Frecenter):
16333 Check that an Emacs fixnum is in range before assigning it to 'int'.
16334 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
16335 values converted from Emacs fixnums.
16336 (Frecenter): Don't wrap around a line count if it is out of 'int'
16337 range; instead, treat it as an extreme value.
16338 (Fset_window_configuration, compare_window_configurations):
16339 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
16341 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
16342 that can exceed INT_MAX. Check that EMACS_INT value is in range
16343 before assigning it to the (possibly-narrower) index.
16344 (match_limit): Don't assume that a fixnum can fit in 'int'.
16346 * print.c (print_object): Use ptrdiff_t, not int, for index that can
16349 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
16350 (Fvertical_motion): Don't wrap around LINES values that don't fit
16351 in 'int'. Instead, treat them as extreme values. This is good
16352 enough for windows, which can't have more than INT_MAX lines anyway.
16354 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16356 * Require libxml/parser.h to avoid compilation warning.
16358 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
16360 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
16361 since this reportedly can destroy thread storage.
16363 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
16365 * syntax.c (find_defun_start): Update all cache variables if
16366 exiting early (Bug#9401).
16368 2011-08-30 Eli Zaretskii <eliz@gnu.org>
16370 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
16372 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
16373 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
16374 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
16376 * term.c (tty_append_glyph): New function.
16377 (produce_stretch_glyph): Static function and its prototype deleted.
16379 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
16382 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
16384 * image.c (parse_image_spec): Check for nonnegative, not for positive,
16385 when checking :margin (Bug#9390).
16386 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
16387 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
16388 so that the name doesn't mislead. All uses changed.
16390 2011-08-28 Johan Bockgård <bojohan@gnu.org>
16392 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
16395 2011-08-27 Eli Zaretskii <eliz@gnu.org>
16397 * xdisp.c (move_it_to): Don't bail out early when reaching
16398 position beyond to_charpos, if we are scanning backwards.
16399 (move_it_vertically_backward): When DY == 0, make sure we get to
16400 the first character in the line after the newline.
16402 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
16404 * ccl.c: Improve and simplify overflow checking (Bug#9196).
16405 (ccl_driver): Do not generate an out-of-range pointer.
16406 (Fccl_execute_on_string): Remove unnecessary check for
16407 integer overflow, noted by Stefan Monnier in
16408 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
16409 Remove a FIXME that didn't need fixing.
16410 Simplify the newly-introduced buffer reallocation code.
16412 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
16414 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
16416 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
16418 Integer and memory overflow issues (Bug#9196).
16420 * doc.c (get_doc_string): Rework so that
16421 get_doc_string_buffer_size is the actual buffer size, rather than
16422 being 1 less than the actual buffer size; this makes xpalloc more
16425 * image.c (x_allocate_bitmap_record, cache_image):
16426 * xselect.c (Fx_register_dnd_atom):
16427 Simplify previous changes by using xpalloc.
16429 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
16430 since either will do and ptrdiff_t is convenient with xpalloc.
16432 * charset.c (charset_table_size)
16433 (struct charset_sort_data.priority): Now ptrdiff_t.
16434 (charset_compare): Don't overflow if priorities differ greatly.
16435 (Fsort_charsets): Don't assume list length fits in int.
16436 Check for size-calculation overflow when allocating sort data.
16437 (syms_of_charset): Allocate an initial charset table that is
16438 just under 64 KiB, to avoid problems with glibc malloc and mmap.
16440 * cmds.c (internal_self_insert): Check for size-calculation overflow.
16442 * composite.h (struct composition.glyph_len): Now int, not unsigned.
16443 The actual value is always <= INT_MAX, and leaving it unsigned made
16444 overflow checking harder.
16446 * dispextern.h (struct glyph_matrix.rows_allocated)
16447 (struct face_cache.size): Now ptrdiff_t, for convenience in use

16458 (revalidate_region_cache, know_region_cache, region_cache_forward)
16459 (region_cache_backward, pp_cache):
16460 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
16461 so that ptrdiff_t * can be passed to xpalloc.

16463 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.

16478 * buffer.c (overlays_at, overlays_in, record_overlay_string)
16480 Don't update size of array until after memory allocation succeeds,
16481 because xmalloc/xrealloc may not return.
16482 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16483 now that we have proper integer overflow checking.
16484 (record_overlay_string, overlay_strings): Catch overflows when

16487 * callproc.c (Fcall_process): Check for size overflow when

16494 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.

16534 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16536 * emacs.c (main): Do not reallocate argv, since there is a null at
16537 the end that can be overwritten, and this way there's no need to
16538 worry about size-calculation overflow.
16539 (sort_args): Check for size-calculation overflow.
16541 * eval.c (init_eval_once, grow_specpdl): Don't update size until

16548 (x_set_alpha): Do not assume XINT fits in int.
16550 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
16551 This is for the members text_lines, text_cols, total_lines, total_cols,
16552 where the system imposes an 'int' limit.

16561 Check for size-calculation overflow.
16562 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
16563 do, as we prefer signed integers.

16570 * gtkutil.h: Change prototypes to match the above.
16572 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

16668 (X_LONG_MIN): New macros.
16669 Use them to make the following changes clearer.
16670 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

16672 future maintainers not to raise the value too much later.
16673 (SELECTION_QUANTUM): Remove, replacing with ...
16674 (selection_quantum): ... new function, which avoids overflow.
16676 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16677 assumption that selection length fits in 'int'.

16694 Don't store size until memory allocation succeeds.
16695 (x_get_window_property): Plug memory leak on memory exhaustion.
16696 Don't double-block input; malloc is safe here. Don't assume 2**34
16697 - 4 fits in unsigned long. Add an xassert to check
16698 XGetWindowProperty overflow. Be more careful about overflow
16699 calculations, and distinguish size from memory overflow better.
16700 (receive_incremental_selection): When tracing, don't assume
16701 unsigned int is less than INT_MAX.
16702 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

16706 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16707 result parameters unless successful. Rely on cons_to_unsigned
16708 to report problems with elements; the old code wasn't right anyway.
16709 (x_check_property_data): Check for int overflow; we cannot use
16710 a wider type due to X limits.

16743 * lisp.h (hash_lookup, hash_put):
16744 * minibuf.c (Ftest_completion):
16745 Use ptrdiff_t for hash table indexes, not int (which is too
16746 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on

16749 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16750 Add a FIXME comment about memory leaks.

16758 with outlandish widths.
16759 * character.h (sanitize_tab_width): Rename from sanitize_width,

16785 (make_lispy_movement): Use same integer type in forward decl
16786 that is used in the definition.

16790 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16791 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16792 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16793 length, not size_t. Use ptrdiff_t for index, not int.
16794 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16795 possibility of integer overflow.

16823 Prefer int to unsigned where either will do.
16824 (tiff_handler): New function, combining the cores of the
16825 old tiff_error_handler and tiff_warning_handler.
16826 This function is rewritten to use vsnprintf and thereby avoid
16827 stack buffer overflows. It uses only the features of vsnprintf
16828 that are common to both POSIX and native Microsoft.
16829 (tiff_error_handler, tiff_warning_handler): Use it.
16830 (tiff_load, gif_load, imagemagick_load_image):
16831 Don't assume :index value fits in 'int'.

16873 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
16874 buffers, return left-to-right.
16875 (set_cursor_from_row): Consider candidate row a win if its glyph
16876 represents a newline and point is on that newline. Fixes cursor
16877 positioning on the newline at EOL of R2L text within L2R
16878 paragraph, and vice versa.
16879 (try_cursor_movement): Check continued rows, in addition to
16880 continuation rows. Fixes unwarranted scroll when point enters a
16881 continued line of R2L text within an L2R paragraph, or vice versa.
16882 (cursor_row_p): Consider the case of point being equal to
16883 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
16884 from the end of a short line to the beginning of a continued line
16885 of R2L text within L2R paragraph.
16886 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

16904 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
16905 extra slot even if the purpose is char-code-property-table.
16907 2011-08-23 Eli Zaretskii <eliz@gnu.org>
16909 * xdisp.c (redisplay_window): When computing centering_position,
16910 account for the height of the header line. (Bug#8874)
16912 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16913 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16914 candidate is selected by the mouse, and that candidate has a
16915 composed character under the mouse.
16917 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16918 coordinates reported by pos-visible-in-window-p for a composed
16919 character in column zero.
16921 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
16923 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
16925 2011-08-22 Eli Zaretskii <eliz@gnu.org>
16927 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
16928 consider it a hit if to_charpos is anywhere in the range of the
16929 composed buffer positions.
16931 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16933 * image.c (gif_load): Don't assume that each subimage has the same
16934 dimensions as the base image. Handle disposal method that is
16935 "undefined" by the gif spec (Bug#9335).
16937 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
16939 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
16940 (Fcondition_case): Document `debug' symbol in error handler.
16942 2011-08-19 Eli Zaretskii <eliz@gnu.org>
16944 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
16945 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
16946 from an Org mode buffer to a Speedbar frame.
16948 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
16949 a composition, take its buffer position from IT->cmp_it.charpos.
16950 Fixes cursor positioning at the beginning of a line that begins
16951 with a composed character.
16953 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16955 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16956 character bidirectional type, use STRONG_L instead. Fixes crashes
16957 in a buffer produced by `describe-categories'.
16959 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16960 members before the level stack, so they would be saved and
16961 restored when copying iterator state. Fixes incorrect reordering
16962 around TABs covered by display properties.
16964 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
16966 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
16968 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
16970 * eval.c (internal_condition_case, internal_condition_case_1)
16971 (internal_condition_case_2, internal_condition_case_n):
16972 Remove unnecessary aborts (Bug#9081).
16974 2011-08-17 Eli Zaretskii <eliz@gnu.org>
16976 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
16977 has no `load' handler, try opening the file locally. (Bug#9311)
16979 2011-08-16 Ken Brown <kbrown@cornell.edu>
16981 * gmalloc.c: Expand comment.
16983 2011-08-16 Eli Zaretskii <eliz@gnu.org>

17031 * process.c (create_process): Call setup_process_coding_systems
17032 after the pid of the process is set to -1 (Bug#8162).
17034 2011-08-14 Eli Zaretskii <eliz@gnu.org>
17036 * xdisp.c (move_it_in_display_line_to): Don't invoke
17037 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
17038 ppos_it. Fixes vertical cursor motion when line beginning is
17039 covered by an image. (Bug#9296)
17041 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
17043 * nsterm.h (ns_run_ascript): Declare.

17047 (ns_run_ascript): New function.
17048 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
17049 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
17050 the event loop. Get status from as_status (Bug#7276).
17052 * nsterm.m (sendEvent): If event is NSApplicationDefined and
17053 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
17054 the event loop (Bug#7276).
17056 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
17058 * gnutls.c (QCgnutls_bootprop_priority)
17059 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
17060 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
17061 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)

17080 (Fnetwork_interface_list): Allocate in increments of bytes instead
17081 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
17082 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
17084 (struct ifflag_def): notrailers is smart on OSX.
17085 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
17086 Get hardware address with getifaddrs if available.
17088 2011-08-12 Eli Zaretskii <eliz@gnu.org>
17090 * xdisp.c (iterate_out_of_display_property): xassert that
17091 IT->position is set to within IT->object's boundaries. Break from
17092 the loop as soon as EOB is reached; avoids infloops in redisplay
17093 when IT->position is set up wrongly due to some bug.
17094 Set IT->current to match the bidi iterator unconditionally.
17095 (push_display_prop): Allow GET_FROM_STRING as IT->method on
17096 entry. Force push_it to save on the stack the current
17097 buffer/string position, to be restored by pop_it. Fix flags in
17098 the iterator structure wrt the object coming from a display
17099 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
17100 properties. (Bug#9284)
17102 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
17104 * fontset.c (fontset_get_font_group): Add proper type checks.

17136 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
17137 to show the arg `TIME' instead of `TIMEVAL'.
17139 2011-08-06 Eli Zaretskii <eliz@gnu.org>
17141 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
17142 display property strides EOL and includes a newline, as in
17143 longlines-mode. (Bug#9254)
17144 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
17145 word-wrap under bidirectional display. (Bug#9224)
17147 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
17148 is non-zero, even if the data buffer is NULL. Fixes a crash in
17149 vertical-motion with longlines-mode. (Bug#9254)
17151 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17153 * bidi.c <bidi_cache_total_alloc>: Now static.

17156 * xdisp.c (display_line): Release buffer allocated for shelved bidi
17159 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
17160 amount allocated this far in `bidi_cache_total_alloc'.
17161 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
17162 non-zero, only free the data buffer without restoring the cache
17163 contents. All callers changed.
17165 * dispextern.h (bidi_unshelve_cache): Update prototype.
17167 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)

17170 to xfree to an equivalent call to bidi_unshelve_cache.
17171 (move_it_in_display_line_to): Fix logic of returning
17172 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
17174 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17176 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that

17227 * bidi.c (bidi_fetch_char): Accept an additional argument
17228 DISP_PROP_P, and pass it to compute_display_string_pos.
17229 Only handle text covered by a display string if DISP_PROP_P is returned
17230 non-zero. All callers of bidi_fetch_char changed.
17232 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>

17264 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
17265 This is needed if max-image-size is a floating-point number.

17317 Without this fix, if a signal arrives just after memory fills up,
17318 'malloc' might be invoked reentrantly.
17320 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
17321 In other words, assume that every image size is allowed, on non-X
17322 hosts. This assumption is probably wrong, but it lets Emacs compile.

17346 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
17347 (bidi_find_other_level_edge):
17348 Use ptrdiff_t instead of EMACS_INT where either will do.
17349 This works better on 32-bit hosts configured --with-wide-int.
17350 (bidi_cache_ensure_space): Check for size-calculation overflow.
17351 Use % rather than repeated addition, for better worst-case speed.
17352 Don't set bidi_cache_size until after xrealloc returns, because it
17354 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
17355 (bidi_cache_ensure_space): Also check that the bidi cache size
17356 does not exceed that of the largest Lisp string or buffer. See Eli
17357 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
17359 * alloc.c (__malloc_size_t): Remove.
17360 All uses replaced by size_t. See Andreas Schwab's note
17361 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
17363 * image.c: Improve checking for integer overflow.
17364 (check_image_size): Assume that f is nonnull, since
17365 it is always nonnull in practice. This is one less thing to
17366 worry about when checking for integer overflow later.
17367 (x_check_image_size): New function, which checks for integer
17368 overflow issues inside X.
17369 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
17370 This removes the need for a memory_full check.
17371 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
17372 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
17373 (xbm_read_bitmap_data): Change locals back to 'int', since
17374 their values must fit in 'int'.
17375 (xpm_load_image, png_load, tiff_load):
17376 Invoke x_create_x_image_and_pixmap earlier,
17377 to avoid much needless work if the image is too large.
17378 (tiff_load): Treat overly large images as if
17379 x_create_x_image_and_pixmap failed, not as malloc failures.
17380 (gs_load): Use x_check_image_size.
17382 * gtkutil.c: Omit integer casts.
17383 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
17384 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
17386 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
17388 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
17389 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
17390 would wrongly return t on a 64-bit host.
17392 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
17393 The plain *_OVERFLOW macros run afoul of GCC bug 49705
17394 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
17395 and therefore cause GCC to emit a bogus diagnostic in some cases.
17397 * image.c: Integer signedness and overflow and related fixes.
17398 This is not an exhaustive set of fixes, but it's time to
17399 record what I've got.
17400 (lookup_pixel_color, check_image_size): Remove redundant decls.
17401 (check_image_size): Don't assume that arbitrary EMACS_INT values
17402 fit in 'int', or that arbitrary 'double' values fit in 'int'.
17403 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
17404 (tiff_load, imagemagick_load_image):
17405 Check for overflow in size calculations.
17406 (x_create_x_image_and_pixmap): Remove unnecessary test for
17407 xmalloc returning NULL; that can't happen.
17408 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
17409 (xpm_color_bucket): Use better integer hashing function.
17410 (xpm_cache_color): Don't possibly over-allocate memory.
17411 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
17412 (gif_memory_source):
17413 Use ptrdiff_t, not int or size_t, to record sizes.
17414 (png_load): Don't assume values greater than 2**31 fit in 'int'.
17415 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
17416 either works, as we prefer signed integers.
17417 (tiff_read_from_memory, tiff_write_from_memory):
17418 Return tsize_t, not size_t, since that's what the TIFF API wants.
17419 (tiff_read_from_memory): Don't fail simply because the read would
17420 go past EOF; instead, return a short read.
17421 (tiff_load): Omit no-longer-needed casts.
17422 (Fimagemagick_types): Don't assume size fits into 'int'.
17424 Improve hashing quality when configured --with-wide-int.
17425 * fns.c (hash_string): New function, taken from sxhash_string.
17426 Do not discard information about ASCII character case; this
17427 discarding is no longer needed.
17428 (sxhash-string): Use it. Change sig to match it. Caller changed.
17429 * lisp.h: Declare it.
17430 * lread.c (hash_string): Remove, since we now use fns.c's version.
17431 The fns.c version returns a wider integer if --with-wide-int is
17432 specified, so this should help the quality of the hashing a bit.
17434 * emacs.c: Integer overflow minor fix.
17435 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
17436 Define only if GNU_LINUX.
17437 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
17439 * dispnew.c: Integer signedness and overflow fixes.
17440 Remove unnecessary forward decls, that were a maintenance hassle.
17441 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
17443 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
17444 (scrolling_window): Use ptrdiff_t, not int, for byte count.
17445 (prepare_desired_row, line_draw_cost):
17446 Use int, not unsigned, where either works.
17447 (save_current_matrix, restore_current_matrix):
17448 Use ptrdiff_t, not size_t, where either works.
17449 (init_display): Check for overflow more accurately, and without
17450 relying on undefined behavior.
17452 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
17453 Remove, replacing with the new symbols in lisp.h. All uses changed.
17454 * fileio.c (make_temp_name):
17455 * filelock.c (lock_file_1, lock_file):
17456 * xdisp.c (message_dolog):
17457 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
17458 Use pMd etc. instead.
17459 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
17460 replacing the pWIDE etc. symbols removed from editfns.c.
17462 * keyboard.h (num_input_events): Now uintmax_t.
17463 This is (very slightly) less likely to mess up due to wraparound.
17466 * buffer.c: Integer signedness fixes.
17467 (alloc_buffer_text, enlarge_buffer_text):
17468 Use ptrdiff_t rather than size_t when either will do, as we prefer
17471 * alloc.c: Integer signedness and overflow fixes.
17472 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
17473 (__malloc_size_t): Default to size_t, not to int.
17474 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
17475 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17476 Prefer ptrdiff_t to size_t when either would do, as we prefer
17478 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17479 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17480 Now const. Initialize with values that are in range even if char
17482 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17483 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17484 These functions do the right thing with sizes > 2**32.
17485 (check_depth): Now ptrdiff_t, not int.
17486 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17487 Adjust to new way of storing sizes. Check for size overflow bugs
17489 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17490 slightly wrong anyway, as it missed one instance of
17491 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17492 (refill_memory_reserve): Omit needless cast to size_t.
17493 (mark_object_loop_halt): Mark as externally visible.
17495 * xselect.c: Integer signedness and overflow fixes.
17496 (Fx_register_dnd_atom, x_handle_dnd_message):
17497 Use ptrdiff_t, not size_t, since we prefer signed.
17498 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17499 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17500 x_dnd_atoms_size and x_dnd_atoms_length.
17502 * doprnt.c: Prefer signed to unsigned when either works.
17504 * doprnt.c (doprnt):
17506 * xdisp.c (vmessage):
17507 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17508 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17509 prefer signed arithmetic to avoid comparison confusion.
17510 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17511 but is a bit tricky.
17513 Assume freestanding C89 headers, string.h, stdlib.h.
17514 * data.c, doprnt.c, floatfns.c, print.c:
17515 Include float.h unconditionally.
17516 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17517 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17518 * regex.c: Likewise for stddef.h, string.h.
17519 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17520 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17521 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17522 (STDC_HEADERS): Remove obsolete defines.
17523 * sysdep.c: Include limits.h unconditionally.
17525 Assume support for memcmp, memcpy, memmove, memset.
17526 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17527 * regex.c (memcmp, memcpy):
17528 Remove; we assume C89 now.
17530 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17531 (__malloc_safe_bcopy): Remove; no longer needed.
17533 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17534 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17535 well either way, and we prefer signed to unsigned.
17537 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17539 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17540 closes the connection while we're reading (bug#9182).
17542 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17544 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17545 are specified (Bug#9168).
17547 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17549 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17550 Found by GCC static checking and --with-wide-int on a 32-bit host.
17552 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17554 * xdisp.c (compute_display_string_pos): Fix logic of caching
17555 previous display string position. Initialize cached_prev_pos to
17556 -1. Fixes slow-down at the beginning of a buffer.
17558 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17560 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17561 for attrs[LFACE_FONTSET_INDEX].
17563 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17565 * xml.c (parse_region): Remove unused local
17566 that was recently introduced.
17568 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17570 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17571 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17573 * xdisp.c (move_it_in_display_line_to): Record the best matching
17574 position for TO_CHARPOS while scanning the line, and restore it on
17575 exit if none of the characters scanned was an exact match.
17576 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17577 when exact match is impossible due to invisible text, and the
17578 lines are truncated.
17580 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17582 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17585 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17587 Fix a significant slow-down of cursor motion with C-n, C-p,
17588 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17589 auto-repeat under bidi redisplay in fontified buffers.
17590 * xdisp.c (compute_stop_pos_backwards): New function.
17591 (next_element_from_buffer): Call compute_stop_pos_backwards to
17592 find a suitable prev_stop when we find ourselves before
17594 (reseat): Don't look for prev_stop, as that could mean a very long
17596 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17597 <cached_disp_overlay_modiff>: Cache for last found display string
17599 (compute_display_string_pos): Return the cached position if asked
17600 about the same buffer in the same area of character positions, and
17601 the buffer wasn't changed since the time the display string
17602 position was cached.
17604 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17606 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17607 is an integer, which is important for empty lines. (Bug#9149)
17609 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17611 * frame.c (Fmodify_frame_parameters): In tty case, update the
17612 default face if necessary (Bug#4238).
17614 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17616 * editfns.c (Fstring_to_char): No need to explain what a character
17617 is in the docstring (Bug#6576).
17619 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17621 * xml.c (parse_region): Make sure we always return a tree.
17623 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17625 * xml.c (parse_region): If a document contains only comments,
17628 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17630 * xml.c (make_dom): Return comments, too.
17632 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17635 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17636 and the surrounding thread.
17637 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17638 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17639 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17641 * s/openbsd.h (BROKEN_SIGIO): Define.
17642 * unexelf.c (unexec) [__OpenBSD__]:
17643 Don't update the .mdebug section of the Alpha COFF symbol table.
17645 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17647 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17650 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17652 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17653 This fixes some race conditions on the permissions of any newly
17656 * alloc.c (valid_pointer_p): Use pipe, not open.
17657 This fixes some permissions issues when debugging.
17659 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17660 If fchown fails to set both uid and gid, try to set just gid,
17661 as that is sometimes allowed. Adjust the file's mode to eliminate
17662 setuid or setgid bits that are inappropriate if fchown fails.
17664 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17666 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
17667 to compare Lisp_Objects.
17668 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
17669 global_gnutls_log_level, don't mistake it for a Lisp_Object.
17670 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
17672 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17674 * lread.c (read_integer): Unread even EOF character.
17675 (read1): Likewise. Properly record start position of symbol.
17677 * lread.c (read1): Read `#:' as empty uninterned symbol if no
17678 symbol character follows.
17680 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17682 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17683 This works around a problem with the previous change to Fcopy_file.
17684 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17685 and without this change, GCC might complain about discarding
17686 fchown's return value.
17688 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17690 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17692 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17694 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17696 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17698 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17699 it's used from the C level.
17701 * process.c: Use the same condition for POLL_FOR_INPUT in both
17702 keyboard.c and process.c (bug#1858).
17704 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17706 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17707 (Fgnutls_boot): Use it.
17709 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17711 * doc.c (Fsubstitute_command_keys): Revert last change.
17713 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17715 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17716 quotes the next character, and doesn't affect other longer
17717 sequences (bug#8935).
17719 * lread.c (syms_of_lread): Clarify that is isn't only
17720 `eval-buffer' and `eval-defun' that's affected by
17721 `lexical-binding' (bug#8460).
17723 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17725 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17726 bidi redisplay when a line includes both an image and is truncated.
17728 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17730 Fix minor problems found by static checking.
17731 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17732 (elsz): Now a signed constant, not a size_t var. We prefer signed
17733 types to unsigned, to avoid integer comparison confusion. Without
17734 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17735 "cannot optimize loop, the loop counter may overflow", a symptom
17737 * indent.c (Fvertical_motion): Mark locals as initialized.
17738 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17740 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
17742 * search.c (Fre_search_backward): Mention `case-fold-search' in
17743 all the re_search_* functions (bug#8138).
17745 * keyboard.c (Fopen_dribble_file): Document when the file is
17748 2011-07-14 Eli Zaretskii <eliz@gnu.org>
17750 * bidi.c (bidi_dump_cached_states): Fix format of displaying
17753 Support bidi reordering of display and overlay strings.
17754 * xdisp.c (compute_display_string_pos)
17755 (compute_display_string_end): Accept additional argument STRING.
17756 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
17757 (reseat_to_string): Initialize bidi_it->string.s and
17758 bidi_it->string.schars.
17759 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
17760 NULL (avoids a crash in bidi_paragraph_init).
17761 Initialize itb.string.lstring.
17762 (init_iterator): Call bidi_init_it only of a valid
17763 buffer position was specified. Initialize paragraph_embedding to
17765 (reseat_to_string): Initialize the bidi iterator.
17766 (display_string): If we need to ignore text properties of
17767 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17768 original value of -1 will not work with bidi.)
17769 (compute_display_string_pos): First arg is now struct
17770 `text_pos *'; all callers changed. Support display properties on
17772 (compute_display_string_end): Support display properties on Lisp
17774 (init_iterator, reseat_1, reseat_to_string): Initialize the
17775 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
17776 when iterating on a string not from display properties).
17777 (compute_display_string_pos, compute_display_string_end):
17778 Fix calculation of the object to scan. Fixes an error when using
17780 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
17781 base_level_stop; instead, set base_level_stop to BEGV.
17782 Fixes crashes in vertical-motion.
17783 (next_element_from_buffer): Improve commentary for when
17784 the iterator is before prev_stop.
17785 (init_iterator): Initialize bidi_p from the default value of
17786 bidi-display-reordering, not from buffer-local value. Use the
17787 buffer-local value only if initializing for buffer iteration.

18260 * alloc.c (mark_buffer):
18261 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
18262 (clone_per_buffer_values): Don't assume that
18263 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
18264 This isn't true in general, and it's particularly not true
18265 if Emacs is configured with --with-wide-int.
18266 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
18267 New macros, used in the buffer.c change.

18303 Random fixes. E.g., (random) never returned negative values.
18304 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
18305 subseconds part to the entropy, as that's a bit more random.
18306 Prefer signed to unsigned, since the signedness doesn't matter and
18307 in general we prefer signed. When given a limit, use a
18308 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
18309 latter isn't right if USE_2_TAGS_FOR_INTS.
18310 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
18311 not 0..VALMASK. Don't discard "excess" bits that random () returns.
18313 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
18315 * textprop.c (text_property_stickiness):
18316 Obey Vtext_property_default_nonsticky.

18323 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
18324 This is more efficient than Ffile_directory_p and avoids a minor race.
18326 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
18328 * buffer.c (Foverlay_put): Say what the return value is
18331 * fileio.c (barf_or_query_if_file_exists): Check first if the file
18332 is a directory before asking whether to use the file name
18334 (barf_or_query_if_file_exists): Make the "File is a directory"
18335 error be more correct.
18337 * fns.c (Frequire): Remove the mention of the .gz files, since
18338 that's installation-specific, but keep the mention of
18339 `get-load-suffixes'.

18343 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

18349 (syms_of_gnutls): Remove duplicate DEFSYM for
18350 Qgnutls_bootprop_verify_hostname_error, an error for
18351 Qgnutls_bootprop_verify_error (which is no longer used).
18353 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
18354 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
18355 Also (re)move comments that are misplaced or no longer relevant.
18357 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
18359 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

18418 (syms_of_keymap): Defsubr make-composed-keymap.
18419 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

18456 * eval.c (struct backtrace): Simplify and port the data structure.
18457 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
18458 signed bit field, as this assumption is not portable and it makes
18459 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
18460 "char debug_on_exit : 1" as this is not portable either; instead,
18461 use the portable "unsigned int debug_on_exit : 1". Remove unused
18462 member evalargs. Remove obsolete comments about cc bombing out.
18464 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

18666 Now ptrdiff_t, not int.
18667 (read1): Don't assume doc string length fits in int. Check for
18668 out-of-range doc string lengths.
18669 (read_list): Don't assume file position fits in int.
18670 (read_escape): Check for hex character overflow.
18672 2011-06-22 Leo Liu <sdl.web@gmail.com>
18674 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
18675 Move to minibuffer.el.
18677 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18679 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
18680 The following patches are for when GLYPH_DEBUG && !XASSERT.
18681 * dispextern.h (trace_redisplay_p, dump_glyph_string):
18682 * dispnew.c (flush_stdout):
18683 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
18684 Mark as externally visible.
18685 * dispnew.c (check_window_matrix_pointers): Now static.
18686 * dispnew.c (window_to_frame_vpos):
18687 * xfns.c (unwind_create_frame):
18688 * xterm.c (x_check_font): Remove unused local.
18689 * scroll.c (CHECK_BOUNDS):
18690 * xfaces.c (cache_fache): Rename local to avoid shadowing.
18691 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
18692 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
18693 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
18694 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
18696 (debug_method_add): Use va_list and vsprintf rather than relying
18697 on undefined behavior with wrong number of arguments.
18698 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18699 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18700 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18701 since we're not interested in debugging glyphs with old libraries.
18702 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18703 GCC 4.6.0's static checking.
18705 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18707 Integer overflow and signedness fixes (Bug#8873).

18716 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
18717 (x_create_bitmap_from_xpm_data):
18718 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
18719 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
18721 * xfaces.c (load_pixmap):
18722 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
18723 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
18724 (.bitmaps_last, struct x_output.icon_bitmap):
18725 Use ptrdiff_t, not int, for bitmap indexes.
18726 (x_allocate_bitmap_record): Check for size overflow.
18727 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
18729 Use ptrdiff_t, not int, for overlay counts.
18730 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
18731 * editfns.c (overlays_around, get_pos_property):
18732 * textprop.c (get_char_property_and_overlay):
18733 * xdisp.c (next_overlay_change, note_mouse_highlight):
18734 * xfaces.c (face_at_buffer_position):
18735 * buffer.c (OVERLAY_COUNT_MAX): New macro.
18736 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
18737 (Fnext_overlay_change, Fprevious_overlay_change)
18738 (mouse_face_overlay_overlaps, Foverlays_in):
18739 Use ptrdiff_t, not int, for sizes.
18740 (overlays_at, overlays_in): Check for size-calculation overflow.
18742 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18744 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18745 (x_session_initialize): Do not assume string length fits in int.
18747 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18748 This is unlikely, but can occur if DPI is outlandish.
18750 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
18751 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
18753 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
18754 * xrdb.c (magic_file_p, search_magic_path):
18755 Omit last arg SUFFIX; it was always 0. All callers changed.
18756 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18758 * xfont.c (xfont_match): Avoid need for strlen.
18760 * xfns.c: Don't assume strlen fits in int.
18761 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
18763 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18764 not unsigned long, as we prefer signed integers. All callers changed.
18765 Detect integer overflow in repeat count.
18766 (message_dolog): Don't assume print length fits in 39 bytes.
18767 (display_mode_element): Don't assume strlen fits in int.
18769 * termcap.c: Don't assume sizes fit in int and never overflow.
18770 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
18771 (gobble_line): Check for size-calculation overflow.
18773 * minibuf.c (Fread_buffer):
18774 * lread.c (intern, intern_c_string):
18775 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
18776 Don't assume string length fits in int.
18778 * keyboard.c (parse_tool_bar_item):
18779 * gtkutil.c (style_changed_cb): Avoid need for strlen.
18781 * font.c: Don't assume string length fits in int.
18782 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
18783 Use ptrdiff_t, not int.
18784 (font_intern_prop): Don't assume string length fits in int.
18785 Don't assume integer property fits in fixnum.
18786 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
18788 * filelock.c: Fix some buffer overrun and integer overflow issues.
18789 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18790 Reformulate so as not to need the command string.
18791 Invoke gzip -cd rather than gunzip, as it's more portable.
18792 (lock_info_type, lock_file_1, lock_file):
18793 Don't assume pid_t and time_t fit in unsigned long.
18794 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18795 (current_lock_owner): Prefer signed type for sizes.
18796 Use memcpy, not strncpy, where memcpy is what is really wanted.
18797 Don't assume (via atoi) that time_t and pid_t fit in int.
18798 Check for time_t and/or pid_t out of range, e.g., via a network share.
18799 Don't alloca where an auto var works fine.
18801 * fileio.c: Fix some integer overflow issues.
18802 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18803 Don't assume string length fits in int.
18804 (directory_file_name): Don't assume string length fits in long.
18805 (make_temp_name): Don't assume pid fits in int, or that its print
18806 length is less than 20.
18808 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
18810 * coding.c (make_subsidiaries): Don't assume string length fits in int.
18812 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
18814 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
18815 We prefer signed integers, even for size calculations.
18817 * emacs.c: Don't assume string length fits in 'int'.
18818 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
18819 (main): Don't invoke strlen when not needed.
18821 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
18822 (XD_DEBUG_MESSAGE): Don't waste a byte.
18824 * callproc.c (getenv_internal_1, getenv_internal)
18825 (Fgetenv_internal):
18826 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18828 * lread.c (invalid_syntax): Omit length argument.
18829 All uses changed. This doesn't fix a bug, but it simplifies the
18830 code away from its former Hollerith-constant appearance, and it's
18831 one less 'int' to worry about when looking at integer-overflow issues.
18832 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18834 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18835 This didn't break anything, but it didn't help either.
18836 It's confusing to put a bogus integer in a place where the actual
18837 value does not matter.
18838 (LIST_END_P): Remove unused macro and its bogus comment.
18839 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18841 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18842 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18844 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18845 We prefer signed types, and the value cannot exceed the EMACS_INT
18846 range anyway (because otherwise the length would not be representable).
18847 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18848 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18849 This avoids a GCC warning when WIDE_EMACS_INT.
18851 * indent.c (sane_tab_width): New function.
18852 (current_column, scan_for_column, Findent_to, position_indentation)
18853 (compute_motion): Use it. This is just for clarity.
18854 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18856 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
18858 * lisp.h (lint_assume): New macro.
18859 * composite.c (composition_gstring_put_cache):
18860 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18862 * editfns.c, insdel.c:
18863 Omit unnecessary forward decls, to simplify future changes.
18865 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18867 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18869 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18870 Use much-faster test for byte-length change.
18871 Don't assume string byte-length fits in 'int'.
18872 Check that character arg fits in 'int'.
18873 (mapcar1): Declare byte as byte, for clarity.
18875 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18877 * fns.c (concat): Catch string overflow earlier.
18878 Do not rely on integer wraparound.
18880 * dispextern.h (struct it.overlay_strings_charpos)
18881 (struct it.selective): Now EMACS_INT, not int.
18882 * xdisp.c (forward_to_next_line_start)
18883 (back_to_previous_visible_line_start)
18884 (reseat_at_next_visible_line_start, next_element_from_buffer):
18885 Don't arbitrarily truncate the value of 'selective' to int.
18887 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18889 * composite.c: Don't truncate sizes to 'int'.
18890 (composition_gstring_p, composition_reseat_it)
18891 (composition_adjust_point): Use EMACS_INT, not int.
18892 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18893 not EMACS_UINT, for indexes.
18895 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18897 * buffer.c: Include <verify.h>.
18898 (struct sortvec.priority, struct sortstr.priority):
18899 Now EMACS_INT, not int.
18900 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18901 (struct sortstr.size, record_overlay_string)
18902 (struct sortstrlist.size, struct sortlist.used):
18903 Don't truncate size to int.
18904 (record_overlay_string): Check for size-calculation overflow.
18905 (init_buffer_once): Check at compile-time, not run-time.
18907 2011-06-22 Jim Meyering <meyering@redhat.com>
18909 Don't leak an XBM-image-sized buffer
18910 * image.c (xbm_load): Free the image buffer after using it.
18912 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18915 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18916 that Sun C diagnosed.
18917 * fns.c (secure_hash): Fix pointer signedness issue.
18918 * intervals.c (static_offset_intervals): New function.
18919 (offset_intervals): Use it.
18921 2011-06-21 Leo Liu <sdl.web@gmail.com>
18924 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18927 * fns.c (secure_hash): Rename from crypto_hash_function and change
18928 the first arg to accept symbols.
18929 (Fsecure_hash): New primitive.
18930 (syms_of_fns): New symbols.
18932 2011-06-20 Deniz Dogan <deniz@dogan.se>
18934 * process.c (Fset_process_buffer): Clarify return value in
18937 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18939 * dispnew.c (add_window_display_history): Use BVAR.
18941 * xdisp.c (debug_method_add): Use BVAR.
18942 (check_window_end, dump_glyph_matrix, dump_glyph)
18943 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18945 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18948 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18949 check till after the cache is created in init_frame_faces.
18951 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18953 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18955 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18957 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18958 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18959 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18961 Improve buffer-overflow checking (Bug#8873).
18962 * fileio.c (Finsert_file_contents):
18963 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18964 Remove the old (too-loose) buffer overflow checks.
18965 They weren't needed, since make_gap checks for buffer overflow.
18966 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18967 The old code merely checked for Emacs fixnum overflow, and relied
18968 on undefined (wraparound) behavior. The new code avoids undefined
18969 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18971 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18972 Tune. Don't use wider integers than needed. Don't use alloca.
18973 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18975 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18977 * insdel.c, lisp.h (buffer_overflow): New function.
18978 (insert_from_buffer_1, replace_range, replace_range_2):
18979 * insdel.c (make_gap_larger):
18980 * editfns.c (Finsert_char):
18981 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18983 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18985 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18987 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18989 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18990 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18992 * fileio.c: Don't assume EMACS_INT fits in off_t.
18993 (emacs_lseek): New static function.
18994 (Finsert_file_contents, Fwrite_region): Use it.
18995 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18997 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18999 * fns.c: Don't overflow int when computing a list length.
19000 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
19001 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
19002 truncation on 64-bit hosts. Check for QUIT every
19003 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
19004 faster and is responsive enough.
19005 (Flength): Report an error instead of overflowing an integer.
19006 (Fsafe_length): Return a float if the value is not representable
19007 as a fixnum. This shouldn't happen except in contrived situations.
19008 (Fnthcdr, Fsort): Don't assume list length fits in int.
19009 (Fcopy_sequence): Don't assume vector length fits in int.
19011 * alloc.c: Check that resized vectors' lengths fit in fixnums.
19012 (header_size, word_size): New constants.
19013 (allocate_vectorlike): Don't check size overflow here.
19014 (allocate_vector): Check it here instead, since this is the only
19015 caller of allocate_vectorlike that could cause overflow.
19016 Check that the new vector's length is representable as a fixnum.
19018 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
19019 The previous code was bogus. For example, next_almost_prime (32)
19020 returned 39, which is undesirable as it is a multiple of 3; and
19021 next_almost_prime (24) returned 25, which is a multiple of 5 so
19022 why was the code bothering to check for multiples of 7?
19024 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
19026 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
19028 Variadic C functions now count arguments with ptrdiff_t.
19029 This partly undoes my 2011-03-30 change, which replaced int with size_t.
19030 Back then I didn't know that the Emacs coding style prefers signed int.
19031 Also, in the meantime I found a few more instances where arguments
19032 were being counted with int, which may truncate counts on 64-bit
19033 machines, or EMACS_INT, which may be unnecessarily wide.
19034 * lisp.h (struct Lisp_Subr.function.aMANY)
19035 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
19036 Arg counts are now ptrdiff_t, not size_t.
19037 All variadic functions and their callers changed accordingly.
19038 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
19039 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
19040 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
19041 * callint.c (Fcall_interactively): Check arg count for overflow,
19042 to avoid potential buffer overrun. Use signed char, not 'int',
19043 for 'varies' array, so that we needn't bother to check its size
19044 calculation for overflow.
19045 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
19046 * eval.c (apply_lambda):
19047 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
19048 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
19049 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
19051 * callint.c (Fcall_interactively): Don't use index var as event count.
19053 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
19054 * mem-limits.h (SIZE): Remove; no longer used.
19056 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
19058 Remove unnecessary casts.
19059 * xterm.c (x_term_init):
19060 * xfns.c (x_set_border_pixel):
19061 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
19062 These aren't needed now that we assume ANSI C.
19064 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
19065 It's more likely to cause problems (due to unsigned overflow)
19068 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
19070 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
19072 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
19074 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
19076 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
19078 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
19080 GLYPH_CODE_FACE returns EMACS_INT, not int.
19081 * dispextern.h (merge_faces):
19082 * xfaces.c (merge_faces):
19083 * xdisp.c (get_next_display_element, next_element_from_display_vector):
19084 Don't assume EMACS_INT fits in int.
19086 * character.h (CHAR_VALID_P): Remove unused parameter.
19087 * fontset.c, lisp.h, xdisp.c: All uses changed.
19089 * editfns.c (Ftranslate_region_internal): Omit redundant test.
19091 * fns.c (concat): Minor tuning based on overflow analysis.
19092 This doesn't fix any bugs. Use int to hold character, instead
19093 of constantly refetching from Emacs object. Use XFASTINT, not
19094 XINT, for value known to be a character. Don't bother comparing
19095 a single byte to 0400, as it's always less.
19097 * floatfns.c (Fexpt):
19098 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
19100 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
19103 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
19105 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
19106 Without this fix, on a 64-bit host (aset S 0 4294967386) would
19107 incorrectly succeed when S was a string, because 4294967386 was
19108 truncated before it was used.
19110 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
19111 Otherwise, an out-of-range integer could cause undefined behavior
19114 * composite.c: Use int, not EMACS_INT, for characters.
19115 (fill_gstring_body, composition_compute_stop_pos): Use int, not
19116 EMACS_INT, for values that are known to be in character range.
19117 This doesn't fix any bugs but is the usual style inside Emacs and
19118 may generate better code on 32-bit machines.
19120 Make sure a 64-bit char is never passed to ENCODE_CHAR.
19121 This is for reasons similar to the recent CHAR_STRING fix.
19122 * charset.c (Fencode_char): Check that character arg is actually
19123 a character. Pass an int to ENCODE_CHAR.
19124 * charset.h (ENCODE_CHAR): Verify that the character argument is no
19125 wider than 'int', as a compile-time check to prevent future regressions
19128 * character.c (char_string): Remove unnecessary casts.
19130 Make sure a 64-bit char is never passed to CHAR_STRING.
19131 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
19132 by silently ignoring the top 32 bits, allowing some values
19133 that were far too large to be valid characters.
19134 * character.h: Include <verify.h>.
19135 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
19136 arguments are no wider than unsigned, as a compile-time check
19137 to prevent future regressions in this area.
19139 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
19140 (Fsubst_char_in_region):
19142 * xdisp.c (decode_mode_spec_coding):
19143 Adjust to CHAR_STRING's new requirement.
19144 * editfns.c (Finsert_char, Fsubst_char_in_region):
19145 * fns.c (concat): Check that character args are actually
19146 characters. Without this test, these functions did the wrong
19147 thing with wildly out-of-range values on 64-bit hosts.
19149 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
19150 These casts should not be needed on 32-bit hosts, either.
19151 * keyboard.c (read_char):
19152 * lread.c (Fload): Remove casts to unsigned.
19154 * lisp.h (UNSIGNED_CMP): New macro.
19155 This fixes comparison bugs on 64-bit hosts.
19156 (ASCII_CHAR_P): Use it.
19157 * casefiddle.c (casify_object):
19158 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
19159 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
19160 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
19161 * dispextern.h (FACE_FROM_ID):
19162 * keyboard.c (read_char): Use UNSIGNED_CMP.
19164 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
19165 not to EMACS_INT, to avoid GCC warning.
19167 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
19169 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
19170 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
19171 isn't needed on 32-bit machines.
19173 * buffer.c (Fgenerate_new_buffer_name):
19174 Use EMACS_INT for count, not int.
19175 (advance_to_char_boundary): Return EMACS_INT, not int.
19177 * data.c (Qcompiled_function): Now static.
19179 * window.c (window_body_lines): Now static.
19181 * image.c (gif_load): Rename local to avoid shadowing.
19183 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
19184 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
19185 * alloc.c (make_save_value): Integer argument is now of type
19186 ptrdiff_t, not int.
19187 (mark_object): Use ptrdiff_t, not int.
19188 * lisp.h (pD): New macro.
19189 * print.c (print_object): Use it.
19191 * alloc.c: Use EMACS_INT, not int, to count objects.
19192 (total_conses, total_markers, total_symbols, total_vector_size)
19193 (total_free_conses, total_free_markers, total_free_symbols)
19194 (total_free_floats, total_floats, total_free_intervals)
19195 (total_intervals, total_strings, total_free_strings):
19196 Now EMACS_INT, not int. All uses changed.
19197 (Fgarbage_collect): Compute overall total using a double, so that
19198 integer overflow is less likely to be a problem. Check for overflow
19199 when converting back to an integer.
19200 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
19201 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
19202 These were 'int' variables that could overflow on 64-bit hosts;
19203 they were never used, so remove them instead of repairing them.
19204 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
19205 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
19206 Previously, this ceilinged at INT_MAX, but that doesn't work on
19208 (allocate_pseudovector): Don't use EMACS_INT when int would do.
19210 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
19211 (allocate_vectorlike): Check for ptrdiff_t overflow.
19212 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
19213 when a (possibly-narrower) signed value would do just as well.
19214 We prefer using signed arithmetic, to avoid comparison confusion.
19216 * alloc.c: Catch some string size overflows that we were missing.
19217 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
19218 for convenience in STRING_BYTES_MAX.
19219 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
19220 The definition here is exact; the one in lisp.h was approximate.
19221 (allocate_string_data): Check for string overflow. This catches
19222 some instances we weren't catching before. Also, it catches
19223 size_t overflow on (unusual) hosts where SIZE_MAX <= min
19224 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
19225 and ptrdiff_t and EMACS_INT are both 64 bits.
19227 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
19228 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
19229 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
19231 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
19233 * alloc.c (Fmake_string): Check for out-of-range init.
19235 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
19237 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
19239 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
19241 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
19242 xg_get_default_scrollbar_width.
19244 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
19245 (int_gtk_range_get_value): Move to the scroll bar part of the file.
19246 (style_changed_cb): Call update_theme_scrollbar_width and call

19248 all frames (Bug#8505).
19249 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
19250 Call gtk_window_set_resizable if HAVE_GTK3.

19252 and height if HAVE_GTK3 (Bug#8505).
19253 (scroll_bar_width_for_theme): New variable.
19254 (update_theme_scrollbar_width): New function.
19255 (xg_get_default_scrollbar_width): Move code to
19256 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.

19259 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
19261 * emacsgtkfixed.c, emacsgtkfixed.h: New files.

19265 * frame.c (make_frame): Call other_buffer_safely instead of
19268 * window.c (temp_output_buffer_show): Call display_buffer with
19269 second argument Vtemp_buffer_show_specifiers and reset latter
19270 immediately after the call.
19271 (Vtemp_buffer_show_specifiers): New variable.
19272 (auto_window_vscroll_p, next_screen_context_lines)
19273 (Vscroll_preserve_screen_position): Remove leading asterisks from

19837 value of a `display' property is a "replacing spec".
19838 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19839 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

19869 * gnutls.c: Use Emacs's memory allocators.
19870 Without this change, the gnutls library would invoke malloc etc.
19871 directly, which causes problems on non-SYNC_INPUT hosts, and which
19872 runs afoul of improving memory_full behavior. (Bug#8761)
19873 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19874 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19875 xfree instead of the default malloc, realloc, free.
19876 (Fgnutls_boot): No need to check for memory allocation failure,
19877 since xmalloc does that for us.

19906 need to be updated by these changes.
19907 * fns.c (make_hash_table, maybe_resize_hash_table):
19908 Check for integer overflow with large hash tables.
19909 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19910 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19911 (SXHASH_REDUCE): New macro.
19912 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19913 Use it instead of discarding useful hash info with large hash values.
19914 (sxhash_float): New function.
19915 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19916 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19917 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19918 Rewrite to use FIXNUM_BITS, as this simplifies things.
19919 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19920 Adjust signatures to match updated version of code.
19921 (consing_since_gc): Now EMACS_INT, since a single hash table can
19922 use more than INT_MAX bytes.

19965 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
19966 * gmalloc.c (register_heapinfo): Use inline unconditionally.
19967 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
19969 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19971 Make it possible to run ./temacs.
19973 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19974 syms_of_callproc does the same thing. Remove test for
19975 "initialized", do it in the caller.
19976 * emacs.c (main): Avoid calling set_initial_environment when dumping.
19978 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
19980 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
19981 (read_minibuf): Use get_minibuffer.
19982 (syms_of_minibuf): Use DEFSYM.
19983 (Qmetadata): New var.
19984 * data.c (Qbuffer): Don't make it static.
19985 (syms_of_data): Use DEFSYM.
19987 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19989 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
19990 (CCL_CODE_MIN): New macro.
19992 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
19994 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
19996 * eval.c (Qdebug): Now static.
19997 * lisp.h (Qdebug): Remove decl. This reverts a part of the
19998 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
19999 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
20001 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20003 * image.c: Various fixes to ImageMagick code comments.
20004 (Fimagemagick_types): Doc fix.
20006 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
20008 Minor fixes prompted by GCC 4.6.0 warnings.
20010 * xselect.c (converted_selections, conversion_fail_tag): Now static.
20012 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
20013 (x_clipboard_manager_save_all): Move extern decl to ...
20014 * xterm.h: ... here, so that it can be checked for consistency.
20016 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20018 * xselect.c (x_clipboard_manager_save_frame)
20019 (x_clipboard_manager_save_all): New functions.
20020 (Fx_clipboard_manager_save): Lisp function deleted.
20022 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
20023 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
20025 * xterm.h: Update prototype.
20027 2011-05-28 William Xu <william.xwl@gmail.com>
20029 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
20030 exiting (Bug#8239).
20032 2011-05-28 Jim Meyering <meyering@redhat.com>
20034 Avoid a sign-extension bug in crypto_hash_function.
20035 * fns.c (to_uchar): Define.
20036 (crypto_hash_function): Use it to convert some newly-signed
20037 variables to unsigned, to avoid sign-extension bugs. For example,
20038 without this change, (md5 "truc") would evaluate to
20039 45723a2aff78ff4fff7fff1114760e62 rather than the expected
20040 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
20041 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
20043 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20045 Integer overflow fixes.
20047 * dbusbind.c: Serial number integer overflow fixes.
20048 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
20049 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
20050 to hold a serial number that is too large for a fixnum.
20051 (Fdbus_method_return_internal, Fdbus_method_error_internal):
20052 Check for serial numbers out of range. Decode any serial number
20053 that was so large that it became a float. (Bug#8722)
20055 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
20056 (Fdbus_call_method, Fdbus_call_method_asynchronously):
20057 Use XFASTINT rather than XUINT when numbers are nonnegative.
20058 (xd_append_arg, Fdbus_method_return_internal):
20059 (Fdbus_method_error_internal): Likewise. Also, for unsigned
20060 arguments, check that Lisp number is nonnegative, rather than
20061 silently wrapping negative numbers around. (Bug#8722)
20062 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
20065 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
20067 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
20069 ccl: Add integer overflow checks.
20070 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
20071 (IN_INT_RANGE): New macros.
20072 (ccl_driver): Use them to check for integer overflow when
20073 decoding a CCL program. Many of the new checks are whether XINT (x)
20074 fits in int; it doesn't always, on 64-bit hosts. The new version
20075 doesn't catch all possible integer overflows, but it's an
20076 improvement. (Bug#8719)
20078 * alloc.c (make_event_array): Use XINT, not XUINT.
20079 There's no need for unsigned here.
20081 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
20082 This follows up to the 2011-05-06 change that substituted uintptr_t
20083 for EMACS_INT. This case wasn't caught back then.
20085 Rework Fformat to avoid integer overflow issues.
20086 * editfns.c: Include <float.h> unconditionally, as it's everywhere
20087 now (part of C89). Include <verify.h>.
20088 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
20089 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
20090 (Fformat): Avoid the prepass trying to compute sizes; it was only
20091 approximate and thus did not catch overflow reliably. Instead, walk
20092 through the format just once, formatting and computing sizes as we go,
20093 checking for integer overflow at every step, and allocating a larger
20094 buffer as needed. Keep track separately whether the format is
20095 multibyte. Keep only the most-recently calculated precision, rather
20096 than them all. Record whether each argument has been converted to
20097 string. Use EMACS_INT, not int, for byte and char and arg counts.
20098 Support field widths and precisions larger than INT_MAX. Avoid
20099 sprintf's undefined behavior with conversion specifications such as %#d
20100 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
20101 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
20102 formatting out-of-range floating point numbers with int
20103 formats. (Bug#8668)
20105 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
20107 * data.c: Avoid integer truncation in expressions involving floats.
20108 * data.c: Include <intprops.h>.
20109 (arith_driver): When there's an integer overflow in an expression
20110 involving floating point, convert the integers to floating point
20111 so that the resulting value does not suffer from catastrophic
20112 integer truncation. For example, on a 64-bit host (* 4
20113 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
20114 Do not rely on undefined behavior after integer overflow.
20116 merge count_size_as_multibyte, parse_str_to_multibyte
20117 * character.c, character.h (count_size_as_multibyte):
20118 Rename from parse_str_to_multibyte; all uses changed.
20119 Check for integer overflow.
20120 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
20121 since it's now a duplicate of the other. This is more of
20122 a character than a buffer op, so better that it's in character.c.
20123 * fns.c, print.c: Adjust to above changes.
20125 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
20127 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
20129 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20131 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20132 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
20133 (x_clipboard_manager_save): Now static.
20134 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
20136 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20137 (crypto_hash_function): Now static.
20138 Fix pointer signedness problems. Avoid unnecessary initializations.
20140 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
20142 * termhooks.h (Vselection_alist): Make it terminal-local.
20144 * terminal.c (create_terminal): Initialize it.
20146 * xselect.c: Support for clipboard managers.
20147 (Vselection_alist): Move to termhooks.h as terminal-local var.
20148 (LOCAL_SELECTION): New macro.
20149 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
20150 (symbol_to_x_atom): Remove gratuitous arg.
20151 (x_handle_selection_request, lisp_data_to_selection_data)
20152 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
20153 (x_own_selection, x_get_local_selection, x_convert_selection):
20154 New arg, specifying work frame. Use terminal-local Vselection_alist.
20155 (some_frame_on_display): Delete unused function.
20156 (Fx_own_selection_internal, Fx_get_selection_internal)
20157 (Fx_disown_selection_internal, Fx_selection_owner_p)
20158 (Fx_selection_exists_p): New optional frame arg.
20159 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
20160 (x_handle_selection_clear): Don't treat other terminals with the
20161 same keyboard specially. Use the terminal-local Vselection_alist.
20162 (x_clear_frame_selections): Use Frun_hook_with_args.
20164 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
20166 * xterm.h: Add support for those atoms.
20168 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
20170 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
20171 (converted_selections, conversion_fail_tag): New global variables.
20172 (x_selection_request_lisp_error): Free the above.
20173 (x_get_local_selection): Remove unnecessary code.
20174 (x_reply_selection_request): Args changed; handle arbitrary array
20175 of converted selections stored in converted_selections.
20176 Separate the XChangeProperty and SelectionNotify steps.
20177 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
20178 (x_convert_selection): New function.
20179 (x_handle_selection_event): Simplify.
20180 (x_get_foreign_selection): Don't ignore incoming requests while
20181 waiting for an answer; this will fail when we implement
20182 SAVE_TARGETS, and seems unnecessary anyway.
20183 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
20184 (Vx_sent_selection_functions): Doc fix.
20186 2011-05-26 Leo Liu <sdl.web@gmail.com>
20188 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
20190 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20192 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
20194 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
20195 for fringe update if it has periodic bitmap.
20196 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
20197 and fringe_bitmap_periodic_p.
20199 * fringe.c (get_fringe_bitmap_data): New function.
20200 (draw_fringe_bitmap_1, update_window_fringes): Use it.
20201 (update_window_fringes): Record periodicity of fringe bitmap in glyph
20202 row. Mark glyph row for fringe update if periodicity changed.
20204 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
20205 for fringe update unless it has periodic bitmap.
20207 2011-05-25 Kenichi Handa <handa@m17n.org>
20209 * xdisp.c (get_next_display_element): Set correct it->face_id for
20210 a static composition.
20212 2011-05-24 Leo Liu <sdl.web@gmail.com>
20215 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
20217 * fns.c (crypto_hash_function, Fsha1): New function.
20218 (Fmd5): Use crypto_hash_function.
20219 (syms_of_fns): Add Ssha1.
20221 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20223 * gnutls.c: Remove unused macros.
20224 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
20225 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
20226 Remove macros that are defined and never used.
20227 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
20229 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20231 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
20232 (Fx_get_selection_internal): Minor cleanup.
20233 (Fx_own_selection_internal): Rename arguments for consistency with
20236 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20238 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
20240 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20242 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
20244 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20246 * dispnew.c (scrolling_window): Don't exclude the case that the
20247 last enabled row in the desired matrix touches the bottom boundary.
20249 2011-05-21 Glenn Morris <rgm@gnu.org>
20251 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
20252 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
20253 and add some more files.
20255 2011-05-20 Eli Zaretskii <eliz@gnu.org>
20257 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
20258 report_file_error introduced by the change from 2011-05-07.
20260 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
20262 * systime.h (Time): Define only if emacs is defined.
20263 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
20264 where the include path doesn't have X11/X.h by default. See
20265 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
20267 2011-05-20 Kenichi Handa <handa@m17n.org>
20269 * composite.c (find_automatic_composition): Fix previous change.
20271 2011-05-20 Glenn Morris <rgm@gnu.org>
20273 * lisp.mk: New file, split from Makefile.in.
20274 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
20275 (shortlisp): Remove.
20276 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
20278 2011-05-19 Glenn Morris <rgm@gnu.org>
20280 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
20281 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
20282 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
20283 (lisp): Set the order to that of loadup.el.
20284 (shortlisp): Make it a copy of $lisp.
20285 (SOME_MACHINE_LISP): Remove.
20286 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
20287 Use just $shortlisp, not $SOME_MACHINE_LISP too.
20289 2011-05-18 Kenichi Handa <handa@m17n.org>
20291 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
20292 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
20293 (find_automatic_composition): Mostly rewrite for efficiency.
20295 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
20297 * makefile.w32-in: Update dependencies.
20299 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
20301 * menu.c: Include limits.h (fixes the MS-Windows build broken by
20302 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
20304 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
20306 Fix some integer overflow issues, such as string length overflow.
20308 * insdel.c (count_size_as_multibyte): Check for string overflow.
20310 * character.c (lisp_string_width): Check for string overflow.
20311 Use EMACS_INT, not int, for string indexes and lengths; in
20312 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
20313 the resulting string length overflows an EMACS_INT; instead,
20314 report a string overflow if no precision given. When checking for
20315 precision exhaustion, use a check that cannot possibly have
20316 integer overflow. (Bug#8675)
20317 * character.h (lisp_string_width): Adjust to new signature.
20319 * alloc.c (string_overflow): New function.
20320 (Fmake_string): Use it. This doesn't change behavior, but saves
20321 a few bytes and will simplify future changes.
20322 * character.c (string_escape_byte8): Likewise.
20323 * lisp.h (string_overflow): New decl.
20325 Fixups, following up to the user-interface timestamp change.
20326 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
20327 for UI timestamps, instead of unsigned long.
20328 * msdos.c (mouse_get_pos): Likewise.
20329 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
20330 * w32gui.h (Time): Define by including "systime.h" rather than by
20331 declaring it ourselves. (Bug#8664)
20333 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
20334 * image.c (clear_image_cache): Likewise.
20336 * term.c (term_mouse_position): Don't assume time_t wraparound.
20338 Be more systematic about user-interface timestamps.
20339 Before, the code sometimes used 'Time', sometimes 'unsigned long',
20340 and sometimes 'EMACS_UINT', to represent these timestamps.
20341 This change causes it to use 'Time' uniformly, as that's what X uses.
20342 This makes the code easier to follow, and makes it easier to catch
20343 integer overflow bugs such as Bug#8664.
20344 * frame.c (Fmouse_position, Fmouse_pixel_position):
20345 Use Time, not unsigned long, for user-interface timestamps.
20346 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
20347 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
20348 * keyboard.h (last_event_timestamp): Likewise.
20349 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
20350 * menu.h (xmenu_show): Likewise.
20351 * term.c (term_mouse_position): Likewise.
20352 * termhooks.h (struct input_event.timestamp): Likewise.
20353 (struct terminal.mouse_position_hook): Likewise.
20354 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
20355 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
20356 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
20357 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
20358 what it was before.
20359 * menu.h, termhooks.h: Include "systime.h", for Time.
20361 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
20362 Don't assume that the difference between two unsigned long values
20363 can fit into an integer. At this point, we know button_down_time
20364 <= event->timestamp, so the difference must be nonnegative, so
20365 there's no need to cast the result if double-click-time is
20366 nonnegative, as it should be; check that it's nonnegative, just in
20367 case. This bug is triggered when events are more than 2**31 ms
20368 apart (about 25 days). (Bug#8664)
20370 * xselect.c (last_event_timestamp): Remove duplicate decl.
20371 (x_own_selection): Remove needless cast to unsigned long.
20373 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
20374 that always fit in int. Use a sentinel instead of a counter, to
20375 avoid a temp and to allay GCC's concerns about possible int overflow.
20376 * frame.h (struct frame): Use int for menu_bar_items_used
20377 instead of EMACS_INT, since it always fits in int.
20379 * menu.c (grow_menu_items): Check for int overflow.
20381 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
20383 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
20384 Before, the code was not consistent. These values cannot exceed
20385 2**31 - 1 so there's no need to make them unsigned.
20386 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
20387 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
20388 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
20390 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
20392 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
20393 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
20394 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
20395 presumably because the widths might not match.
20397 * window.c (size_window): Avoid needless test at loop start.
20399 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
20401 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
20403 2011-05-12 Drew Adams <drew.adams@oracle.com>
20405 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
20407 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20409 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
20410 `width' to `bar_area_x' and `bar_area_width', respectively.
20411 (x_scroll_run): Take account of fringe background extension.
20413 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
20414 Rename local vars `left' and `width' to `bar_area_x' and
20415 `bar_area_width', respectively.
20416 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
20417 background extension.
20419 2011-05-10 Jim Meyering <meyering@redhat.com>
20421 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
20423 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
20425 * image.c (Finit_image_library): Return t for built-in image types,
20426 like pbm and xbm. (Bug#8640)
20428 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
20430 * w32menu.c (set_frame_menubar): Fix submenu allocation.
20432 2011-05-07 Eli Zaretskii <eliz@gnu.org>
20434 * w32console.c (Fset_screen_color): Doc fix.
20435 (Fget_screen_color): New function.
20436 (syms_of_ntterm): Defsubr it.
20438 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
20439 unlink the temporary file if Fcall_process didn't create it in the
20441 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
20442 child process will be redirected to a file specified with `:file'.
20443 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
20444 cue to call_process_cleanup not to close that handle.
20446 2011-05-07 Ben Key <bkey76@gmail.com>
20448 * makefile.w32-in: The bootstrap-temacs rule now makes use of
20449 one of two shell specific rules, either bootstrap-temacs-CMD or
20450 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
20451 to the previous implementation of the bootstrap-temacs rule.
20452 The bootstrap-temacs-CMD rule is similar to the previous
20453 implementation of the bootstrap-temacs rule except that it
20454 makes use of the ESC_CFLAGS variable instead of the CFLAGS
20457 These changes, along with some changes to nt/configure.bat,
20458 nt/gmake.defs, and nt/nmake.defs, are required to extend my
20459 earlier fix to add support for --cflags and --ldflags options
20460 that include quotes so that it works whether make uses cmd or
20463 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
20465 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
20466 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
20468 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
20469 a string. Handle both cases.
20470 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
20471 (Fdbus_register_method): Use Qinvalid_function.
20473 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20475 * makefile.w32-in: Update dependencies.
20476 (LISP_H): Add inttypes.h and stdin.h.
20477 (PROCESS_H): Add unistd.h.
20479 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20481 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20482 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20484 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20486 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20488 * term.c (vfatal): Remove stray call to va_end.
20489 It's not needed and the C Standard doesn't allow it here anyway.
20491 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20492 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20494 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20497 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20499 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20501 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20503 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20505 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20507 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20508 * charset.c (Fdefine_charset_internal): Don't initialize
20509 charset.code_space[15]. The value was garbage, on hosts with
20510 32-bit int (Bug#8600).
20512 * lread.c (read_integer): Be more consistent with string-to-number.
20513 Use string_to_number to do the actual conversion; this avoids
20514 rounding errors and fixes some other screwups. Without this fix,
20515 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20516 (digit_to_number): Move earlier, for benefit of read_integer.
20517 Return -1 if the digit is out of range for the base, -2 if it is
20518 not a digit in any supported base. (Bug#8602)
20520 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20522 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20523 to match comment at start of function. This also removes a
20524 GCC warning about overflow in a 32+64-bit port.
20526 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20528 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20529 Reported by Stefan Monnier in
20530 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20531 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20532 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20534 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20535 (EMACS_UINTPTR): Likewise, with uintptr_t.
20537 * lisp.h: Prefer 64-bit EMACS_INT if available.
20538 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20539 on 32-bit hosts that have 64-bit int, so that they can access
20541 However, temporarily disable this change unless the temporary
20542 symbol WIDE_EMACS_INT is defined.
20544 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20546 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20547 This removes an assumption that EMACS_INT and long are the same
20548 width as pointers. The assumption is true for Emacs porting targets
20549 now, but we want to make other targets possible.
20550 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20551 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20552 In the rest of the code, change types of integers that hold casted
20553 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20554 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20555 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20556 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20557 No need to cast type when ORing.
20558 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20559 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20560 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20561 assume EMACS_INT is the same width as char *.
20562 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20563 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20564 Remove no-longer-needed casts.
20565 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20566 (xg_tool_bar_help_callback, xg_make_tool_item):
20567 Use EMACS_INTPTR to hold an integer
20568 that will be cast to void *; this can avoid a GCC warning
20569 if EMACS_INT is not the same width as void *.
20570 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20571 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20572 (current_message_1, set_message_1):
20573 Use a local to convert to proper width without a cast.
20574 * xmenu.c (dialog_selection_callback): Likewise.
20576 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20577 Also, don't assume VALBITS / RAND_BITS is less than 5,
20578 and don't rely on undefined behavior when shifting a 1 left into
20580 * lisp.h (get_random): Change signature to match.
20582 * lread.c (hash_string): Use size_t, not int, for hash computation.
20583 Normally we prefer signed values; but hashing is special, because
20584 it's better to use unsigned division on hash table sizes so that
20585 the remainder is nonnegative. Also, size_t is the natural width
20586 for hashing into memory. The previous code used 'int', which doesn't
20587 retain enough info to hash well into very large tables.
20588 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20590 * dbusbind.c: Don't possibly lose pointer info when converting.
20591 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20592 Use XPNTR rather than XHASH, so that the high-order bits of
20593 the pointer aren't lost when converting through void *.
20595 * eval.c (Fautoload): Don't double-shift a pointer.
20597 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
20599 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20601 * gnutls.c (DEF_GNUTLS_FN):
20602 * image.c (DEF_IMGLIB_FN): Make function pointers static.
20604 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
20606 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
20609 2011-05-05 Eli Zaretskii <eliz@gnu.org>
20611 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
20612 New version that can reserve upto 2GB of heap space.
20614 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
20616 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).

20623 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
20625 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
20626 Update dependencies.
20628 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20630 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
20631 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
20632 Remove unused parameter `fildes'.
20633 * process.c (read_process_output, send_process): Don't pass it.
20635 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20637 Fix previous change: the library cache is defined in w32.c.
20638 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
20639 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
20641 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20643 Implement dynamic loading of GnuTLS on Windows.
20645 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
20646 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
20647 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20650 * gnutls.c (Qgnutls_dll): Define.
20651 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
20652 (gnutls_*): Declare function pointers.

20656 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20657 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
20658 (emacs_gnutls_write, emacs_gnutls_read)
20659 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
20660 (Fgnutls_available_p): New function.
20661 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

20671 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
20673 * w32.c (QCloaded_from, Vlibrary_cache): Define.
20674 (w32_delayed_load): Move from image.c. When loading a library, record
20675 its filename in the :loaded-from property of the library id.
20676 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
20677 Initialize and staticpro them.

20681 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20682 instead of gnutls_record_check_pending.
20684 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
20686 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20688 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
20689 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
20692 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
20694 * xterm.c (x_set_frame_alpha): Do not set property on anything

20718 (wait_for_termination, interruptible_wait_for_termination):
20719 Move after wait_for_termination_1.
20721 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
20723 * sysdep.c (interruptible_wait_for_termination): New function
20724 which is like wait_for_termination, but allows keyboard
20727 * callproc.c (Fcall_process): Add (:file "file") as an option for
20729 (Fcall_process_region): Ditto.
20731 2011-04-30 Eli Zaretskii <eliz@gnu.org>
20733 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
20734 rather than `XVECTOR (FOO)->size'.
20736 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20737 inttypes.h, as a gnulib replacement is used if it not available in
20740 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20742 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
20743 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
20744 of MOST_POSITIVE_FIXNUM. (Bug#8528)
20746 * coding.c (coding_alloc_by_realloc): Error out if destination
20747 will grow beyond MOST_POSITIVE_FIXNUM.

20762 simple variables to record original value of point. (Bug#7952)
20764 * doprnt.c (doprnt): Fix the case where a multibyte sequence
20765 produced by %s or %c overflows available buffer space. (Bug#8545)
20767 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20769 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

20804 Improve `doprnt' and its usage. (Bug#8545)
20805 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20806 `format_end'. Remove support for %l as a conversion specifier.
20807 Don't use xrealloc. Improve diagnostics when the %l size modifier
20808 is used. Update the commentary.
20810 * eval.c (verror): Simplify calculation of size_t.
20812 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20815 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20817 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20820 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20822 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20823 This makes this file independent of the recent pseudovector change.
20825 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20827 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20829 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20830 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20831 Remove unused local.
20832 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20834 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20835 GCC 4.6.0 optimizes based on type-based alias analysis.
20836 For example, if b is of type struct buffer * and v of type struct
20837 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20838 != &v->size, and therefore "v->size = 1; b->size = 2; return
20839 v->size;" must therefore return 1. This assumption is incorrect
20840 for Emacs, since it type-puns struct Lisp_Vector * with many other
20841 types. To fix this problem, this patch adds a new type struct
20842 vectorlike_header that documents the constraints on layout of vectors
20843 and pseudovectors, and helps optimizing compilers not get fooled
20844 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20845 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20846 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20848 (XSETPVECTYPE): Rewrite in terms of new macro.
20849 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20850 This is a bit clearer, and further avoids the possibility of
20851 undesirable aliasing.
20852 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20853 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20854 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20855 since Lisp_Subr is a special case (no "next" field).
20856 (ASIZE): Now uses header.size rather than size.
20857 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20858 to avoid the hassle of writing XVECTOR (foo)->header.size.
20859 (struct vectorlike_header): New type.
20860 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20861 object, to help avoid aliasing.
20862 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20863 (SUBRP): Likewise, since Lisp_Subr is a special case.
20864 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20865 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20866 (struct Lisp_Hash_Table): Combine first two members into a single
20867 struct vectorlike_header member. All uses of "size" and "next" members
20868 changed to be "header.size" and "header.next".
20869 * buffer.h (struct buffer): Likewise.
20870 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20871 * frame.h (struct frame): Likewise.
20872 * process.h (struct Lisp_Process): Likewise.
20873 * termhooks.h (struct terminal): Likewise.
20874 * window.c (struct save_window_data, struct saved_window): Likewise.
20875 * window.h (struct window): Likewise.
20876 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20877 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20878 * buffer.c (init_buffer_once): Likewise.
20879 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20881 * process.c (Fformat_network_address): Use local var for size,
20884 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20886 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20887 * data.c (atof): Remove decl; no longer used or needed.
20888 (digit_to_number): Move to lread.c.
20889 (Fstring_to_number): Use new string_to_number function, to be
20890 consistent with how the Lisp reader treats infinities and NaNs.
20891 Do not assume that floating-point numbers represent EMACS_INT
20892 without losing information; this is not true on most 64-bit hosts.
20893 Avoid double-rounding errors, by insisting on integers when
20894 parsing non-base-10 numbers, as the documentation specifies.
20895 * lisp.h (string_to_number): New decl, replacing ...
20896 (isfloat_string): Remove.
20897 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20898 (read1): Do not accept +. and -. as integers; this
20899 appears to have been a coding error. Similarly, do not accept
20900 strings like +-1e0 as floating point numbers. Do not report
20901 overflow for integer overflows unless the base is not 10 which
20902 means we have no simple and reliable way to continue.
20903 Break out the floating-point parsing into a new
20904 function string_to_number, so that Fstring_to_number parses
20905 floating point numbers consistently with the Lisp reader.
20906 (digit_to_number): Move here from data.c. Make it static inline.
20907 (E_CHAR, EXP_INT): Remove, replacing with ...
20908 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20909 (string_to_number): New function, replacing isfloat_string.
20910 This function checks for valid syntax and produces the resulting
20911 Lisp float number too. Rework it so that string-to-number
20912 no longer mishandles examples like "1.0e+". Use strtoumax,
20913 so that overflow for non-base-10 numbers is reported only when
20914 there's no portable and simple way to convert to floating point.
20916 * textprop.c (set_text_properties_1): Rewrite for clarity,
20917 and to avoid GCC warning about integer overflow.
20919 * intervals.h (struct interval): Use EMACS_INT for members
20920 where EMACS_UINT might cause problems. See
20921 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20922 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20923 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20925 (offset_intervals): Tell GCC not to worry about length overflow
20926 when negating a negative length.
20928 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20929 (overrun_check_free): Likewise.
20931 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20932 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20935 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20936 (gnutls_make_error): Rename local to avoid shadowing.
20937 (gnutls_emacs_global_deinit): ifdef out; not used.
20938 (Fgnutls_boot): Use const for pointer to readonly storage.
20939 Comment out unused local. Fix pointer signedness problems.
20941 * lread.c (openp): Don't stuff size_t into an 'int'.
20942 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20943 about possible signed overflow.
20945 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20946 (GDK_KEY_g): Don't define if already defined.
20947 (xg_prepare_tooltip): Avoid pointer signedness problem.
20948 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20950 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20951 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20953 * xfns.c (Fx_window_property): Simplify a bit,
20954 to make a bit faster and to avoid GCC 4.6.0 warning.
20955 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20957 * fns.c (internal_equal): Don't assume size_t fits in int.
20959 * alloc.c (compact_small_strings): Tighten assertion a little.
20961 Replace pEd with more-general pI, and fix some printf arg casts.
20962 * lisp.h (pI): New macro, generalizing old pEd macro to other
20963 conversion specifiers. For example, use "...%"pI"d..." rather
20964 than "...%"pEd"...".
20965 (pEd): Remove. All uses replaced with similar uses of pI.
20966 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20967 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20968 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20969 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20970 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20971 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20972 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20974 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20975 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20976 * print.c (safe_debug_print, print_object): Likewise.
20977 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20979 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20980 avoiding the 0 flag, which is not portable.
20981 * process.c (Fmake_network_process): Use pI to avoid cast.
20982 * region-cache.c (pp_cache): Likewise.
20983 * xdisp.c (decode_mode_spec): Likewise.
20984 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
20985 behavior on 64-bit hosts with printf arg.
20986 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
20987 (x_stop_queuing_selection_requests): Likewise.
20988 (x_get_window_property): Don't truncate byte count to an 'int'
20991 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20992 here, since it parses constructs like leading '-' and spaces,
20993 which are not wanted; and it overflows with large numbers.
20994 Instead, simply match F[0-9]+, which is what is wanted anyway.
20996 * alloc.c: Remove unportable assumptions about struct layout.
20997 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20998 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20999 (allocate_vectorlike, make_pure_vector): Use the new macros,
21000 plus offsetof, to remove unportable assumptions about struct layout.
21001 These assumptions hold on all porting targets that I know of, but
21002 they are not guaranteed, they're easy to remove, and removing them
21003 makes further changes easier.
21005 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
21006 This doesn't fix a bug but makes the code clearer.
21007 (string_overrun_cookie): Now const. Use initializers that
21008 don't formally overflow signed char, to avoid warnings.
21009 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
21010 can cause Emacs to crash when string overrun checking is enabled.
21011 (allocate_buffer): Don't assume sizeof (struct buffer) is a
21012 multiple of sizeof (EMACS_INT); it need not be, if
21013 alignof(EMACS_INT) < sizeof (EMACS_INT).
21014 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
21016 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

21023 supposed to be handshaking. (Bug#8556)
21024 Reported by Paul Eggert <eggert@cs.ucla.edu>.

21031 (handle_user_signal): Break into debugger when debug-on-event
21032 matches the current signal symbol.
21034 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
21036 * alloc.c (check_sblock, check_string_bytes)
21037 (check_string_free_list): Convert to standard C.
21039 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
21041 * w32.c (emacs_gnutls_push): Fix typo.
21043 2011-04-25 Eli Zaretskii <eliz@gnu.org>
21045 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
21046 "cast to pointer from integer of different size".
21048 Improve doprnt and its use in verror. (Bug#8545)
21049 * doprnt.c (doprnt): Document the set of format control sequences
21050 supported by the function. Use SAFE_ALLOCA instead of always
21053 * eval.c (verror): Don't limit the buffer size at size_max-1, that
21054 is one byte too soon. Don't use xrealloc; instead xfree and
21057 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
21059 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
21062 * gnutls.c: Renamed global_initialized to
21063 gnutls_global_initialized. Added internals for the
21064 :verify-hostname-error, :verify-error, and :verify-flags
21065 parameters of `gnutls-boot' and documented those parameters in the
21066 docstring. Start callback support.
21067 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
21068 unless a fatal error occurred. Call gnutls_alert_send_appropriate
21069 on error. Return error code.

21071 (emacs_gnutls_read): Likewise.
21072 (Fgnutls_boot): Return handshake error code.

21141 * doprnt.c: Include limits.h.
21142 (SIZE_MAX): New macro.
21143 (doprnt): Return a size_t value. 2nd arg is now size_t.
21144 Many local variables are now size_t instead of int or unsigned.
21145 Improve overflow protection. Support `l' modifier for integer
21146 conversions. Support %l conversion. Don't assume an EMACS_INT
21147 argument for integer conversions and for %c.
21149 * lisp.h (doprnt): Restore prototype.
21151 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
21152 $(SRC)/character.h.
21154 * Makefile.in (base_obj): Add back doprnt.o.
21156 * deps.mk (doprnt.o): Add back prerequisites.
21157 (callint.o): Depend on character.h.
21159 * eval.c (internal_lisp_condition_case): Include the handler
21160 representation in the error message.
21161 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
21162 when breaking from the loop.

21166 * callint.c (Fcall_interactively): When displaying error message
21167 about invalid control letter, pass the character's codepoint, not
21168 a pointer to its multibyte form. Improve display of the character
21169 in octal and display also its hex code.
21171 * character.c (char_string): Use %x to display the (unsigned)
21172 codepoint of an invalid character, to avoid displaying a bogus
21175 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
21176 `error', not SYMBOL_NAME itself.
21178 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
21179 character arguments to `error'.
21181 * charset.c (check_iso_charset_parameter): Fix incorrect argument
21182 to `error' in error message about FINAL_CHAR argument. Make sure
21183 FINAL_CHAR is a character, and use %c when it is passed as
21184 argument to `error'.

21248 Define only if needed.
21250 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
21251 by pacifying GCC about it. Maybe it's time to retire it?
21252 * xfaces.c (USG, __TIMEVAL__): Likewise.
21254 * dispextern.h (struct redisplay_interface): Rename param
21255 to avoid shadowing.
21256 * termhooks.h (struct terminal): Likewise.
21257 * xterm.c (xembed_send_message): Likewise.
21259 * insdel.c (make_gap_smaller): Define only if
21260 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
21262 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
21265 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
21266 so that we aren't warned about unused symbols.
21268 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
21270 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
21272 * xfns.c (x_real_positions): Mark locals as initialized.
21274 * xmenu.c (xmenu_show): Don't use uninitialized vars.
21276 * xterm.c: Fix problems found by static analysis with other toolkits.
21277 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
21278 (x_dispatch_event): Declare static if USE_GTK, and
21279 define if USE_GTK || USE_X_TOOLKIT.
21280 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.

21373 * nsfont.m: Fixed bugs in ns_get_family and
21374 ns_descriptor_to_entity that were caused by using free to
21375 deallocate memory blocks that were allocated by xmalloc (via

21377 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
21378 --enable-checking=xmallocoverrun). xfree is now used to
21379 deallocate these memory blocks.

21720 * ccl.c (Vccl_program_table): Now static.
21721 (check_ccl_update): Remove; unused.
21723 * category.c (SET_CATEGORY_SET, set_category_set): Move here.
21724 * category.h: ... from here.
21725 * category.c (check_category_table, set_category_set): Now static.
21727 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
21728 * lisp.h: Remove these decls.
21730 * buffer.c (buffer_count): Remove unused var.
21732 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
21733 so that it's not optimized away.
21734 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
21735 * dispextern.h (bidi_dump_cached_states): Remove, since it's
21736 exported only to the debugger.
21738 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
21739 * atimer.h (run_all_atimers): Remove; not exported.
21741 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
21742 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
21743 was inaccessible from Lisp.
21744 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
21745 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
21747 alloc.c: Import and export fewer symbols, and remove unused items.
21748 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
21750 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
21751 it's not optimized away by whole-program optimization.
21752 (message_enable_multibyte, free_misc): Remove.
21753 (catchlist, handlerlist, mark_backtrace):
21754 Declare only if BYTE_MARK_STACK.
21755 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
21756 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
21757 (message_enable_multibyte): Remove decl.
21758 (free_misc, interval_free_list, float_block, float_block_index):
21759 (n_float_blocks, float_free_list, cons_block, cons_block_index):
21760 (cons_free_list, last_marked_index):
21762 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
21763 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
21764 (mark_backtrace): Define only if BYTE_MARK_STACK.
21765 * xdisp.c (message_enable_multibyte): Now static.
21767 Declare Lisp_Object Q* variables to be 'static' if not exported.
21768 This makes it easier for human readers (and static analyzers)
21769 to see whether these variables are used from other modules.
21770 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
21771 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
21772 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

21775 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
21776 * xmenu.c, xselect.c:
21777 Declare Q* vars static if they are not used in other modules.
21778 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
21779 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
21780 Remove decls of unexported vars.
21781 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
21783 * lisp.h (DEFINE_FUNC): Make sname 'static'.
21785 Make Emacs functions such as Fatom 'static' by default.
21786 This makes it easier for human readers (and static analyzers)
21787 to see whether these functions can be called from other modules.
21788 DEFUN now defines a static function. To make the function external
21789 so that it can be used in other C modules, use the new macro DEFUE.
21790 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
21791 (Finit_image_library):
21792 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
21793 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
21794 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
21795 Remove decls, since these functions are now static.
21796 (Funintern, Fget_internal_run_time): New decls, since these functions
21797 were already external.
21799 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
21800 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

21806 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
21807 Mark functions with DEFUE instead of DEFUN,
21808 if they are used in other modules.
21809 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
21810 decls for now-static functions.
21811 * buffer.h (Fdelete_overlay): Remove decl.
21812 * callproc.c (Fgetenv_internal): Mark as internal.
21813 * composite.c (Fremove_list_of_text_properties): Remove decl.

21820 * fileio.c (Fmake_symbolic_link): New forward static decl.
21821 * image.c (Finit_image_library): New forward static decl.
21822 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
21823 * intervals.h (Fprevious_property_change):
21824 (Fremove_list_of_text_properties): Remove decls.
21825 * keyboard.c (Fthis_command_keys): Remove decl.
21826 (Fcommand_execute): New forward static decl.
21827 * keymap.c (Flookup_key): New forward static decl.
21828 (Fcopy_keymap): Now static.
21829 * keymap.h (Flookup_key): Remove decl.

21844 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
21847 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21849 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21850 when at ZV. (Bug#8487)
21852 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
21854 * charset.c (Fclear_charset_maps): Use xfree instead of free.

21857 * sound.c (sound_cleanup, alsa_close): Likewise.
21858 * termcap.c (tgetent): Likewise.
21859 * xfns.c (x_default_font_parameter): Likewise.
21860 * xsettings.c (read_and_apply_settings): Likewise.
21862 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21863 (overrun_check_free): Protoize.
21865 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21867 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21868 since callers should never pass a negative size.
21869 Change the signature to match that of plain 'read' and 'write'; see
21870 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21871 * lisp.h: Update prototypes of emacs_write and emacs_read.
21873 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21875 * xdisp.c (redisplay_window): Don't try to determine the character
21876 position of the scroll margin if the window start point w->startp
21877 is outside the buffer's accessible region. (Bug#8468)
21879 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21881 Fix write-region and its subroutines for buffers > 2GB.
21882 * fileio.c (a_write, e_write): Modify declaration of arguments and
21883 local variables to support buffers larger than 2GB.
21884 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21886 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21887 argument, local variables, and return value.
21889 * lisp.h: Update prototypes of emacs_write and emacs_read.
21891 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21893 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21895 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21897 Fix more problems found by GCC 4.6.0's static checks.
21899 * xdisp.c (vmessage): Use a better test for character truncation.
21901 * charset.c (load_charset_map): <, not <=, for optimization,
21902 and to avoid potential problems with integer overflow.
21903 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21904 * casetab.c (set_identity, shuffle): Likewise.
21905 * editfns.c (Fformat): Likewise.
21906 * syntax.c (skip_chars): Likewise.
21908 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21909 This also lets GCC 4.6.0 generate slightly better loop code.
21911 * callint.c (Fcall_interactively): <, not <=, for optimization.
21912 (Fcall_interactively): Count the number of arguments produced,
21913 not the number of arguments given. This is simpler and lets GCC
21914 4.6.0 generate slightly better code.
21916 * ftfont.c: Distingish more carefully between FcChar8 and char.
21917 The previous code passed unsigned char * to a functions like
21918 strlen and xstrcasecmp that expect char *, which does not
21919 conform to the C standard.
21920 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21921 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21922 char * when the C standard requires it.
21924 * keyboard.c (read_char): Remove unused var.
21926 * eval.c: Port to Windows vsnprintf (Bug#8435).
21927 Include <limits.h>.
21928 (SIZE_MAX): Define if the headers do not.
21929 (verror): Do not give up if vsnprintf returns a negative count.
21930 Instead, grow the buffer. This ports to Windows vsnprintf, which
21931 does not conform to C99. Problem reported by Eli Zaretskii.
21932 Also, simplify the allocation scheme, by avoiding the need for
21933 calling realloc, and removing the ALLOCATED variable.
21935 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21937 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21938 But keep the doprint source code for now, as we might revamp it
21939 and use it again (Bug#8435).
21940 * lisp.h (doprnt): Remove.
21941 * Makefile.in (base_obj): Remove doprnt.o.
21942 * deps.mk (doprnt.o): Remove.
21944 error: Print 32- and 64-bit integers portably (Bug#8435).
21945 Without this change, on typical 64-bit hosts error ("...%d...", N)
21946 was used to print both 32- and 64-bit integers N, which relied on
21947 undefined behavior.
21948 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21949 * lisp.h (error, verror): Mark as printf-like functions.
21950 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21951 Report overflow in size calculations when allocating printf buffer.
21952 Do not truncate output string at its first null byte.
21953 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21954 Truncate the output at a character boundary, since vsnprintf does not
21956 * charset.c (check_iso_charset_parameter): Convert internal
21957 character to string before calling 'error', since %c now has the
21959 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21960 overflow when computing char to be passed to 'error'. Do not
21961 pass Lisp_Object to 'error'; pass the integer instead.
21962 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21963 formatted with plain %d.
21965 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21967 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
21969 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
21971 * xterm.c (x_catch_errors): Remove duplicate declaration.
21973 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
21975 * xdisp.c, lisp.h (message_nolog): Remove; unused.
21977 2011-04-10 Jim Meyering <meyering@redhat.com>
21979 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
21980 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
21981 return ssize_t not "int", and use size_t as the buffer length.
21982 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
21983 * gnutls.h: Update declarations.
21984 * process.c (read_process_output): Use ssize_t, to match.
21985 (send_process): Likewise.
21987 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21989 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
21991 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21993 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
21994 Use unsigned char, to match FcChar8 type definition.
21996 * xterm.c (handle_one_xevent):
21997 * xmenu.c (create_and_show_popup_menu):
21998 * xselect.c (x_decline_selection_request)
21999 (x_reply_selection_request): Avoid type-punned deref of X events.
22001 2011-04-09 Eli Zaretskii <eliz@gnu.org>
22003 Fix some uses of `int' instead of EMACS_INT.
22004 * search.c (string_match_1, fast_string_match)
22005 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
22006 (scan_buffer, find_next_newline_no_quit)
22007 (find_before_next_newline, search_command, Freplace_match)
22008 (Fmatch_data): Make some `int' variables be EMACS_INT.
22010 * xdisp.c (display_count_lines): 3rd argument and return value now
22011 EMACS_INT. All callers changed.
22012 (pint2hrstr): Last argument is now EMACS_INT.
22014 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
22015 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
22016 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
22017 (decode_coding_utf_16, decode_coding_emacs_mule)

22019 (decode_coding_ccl, decode_coding_charset)
22020 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
22021 (decode_coding_iso_2022, decode_coding_emacs_mule)
22022 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
22023 <char_offset, last_offset>: Declare EMACS_INT.

22027 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
22028 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
22030 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
22031 (encode_invocation_designation): Last argument P_NCHARS is now
22033 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
22034 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
22036 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
22039 * ccl.c (Fccl_execute_on_string): Declare some variables
22042 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
22044 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
22046 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
22048 * process.c (Fformat_network_address): Doc fix.
22050 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
22052 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
22054 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
22056 * keyboard.c (read_char): Call Lisp function help-form-show,
22057 instead of using internal_with_output_to_temp_buffer.
22058 (Qhelp_form_show): New var.
22059 (syms_of_keyboard): Use DEFSYM macro.
22061 * print.c (internal_with_output_to_temp_buffer): Function deleted.

22068 (list_processes_1): Delete.
22070 2011-04-06 Eli Zaretskii <eliz@gnu.org>
22072 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
22074 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
22076 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
22078 Fix more problems found by GCC 4.6.0's static checks.
22080 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
22082 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
22084 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
22086 * xdisp.c (vmessage): Mark as a printf-like function.
22088 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
22090 * sound.c (sound_warning): Don't crash if arg contains a printf format.
22092 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
22093 printf-like functions.
22094 (tiff_load): Add casts to remove these marks before passing them
22095 to system-supplied API.
22097 * eval.c (Fsignal): Remove excess argument to 'fatal'.
22099 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
22100 This avoids several warnings with gcc -Wstrict-overflow.
22101 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
22102 directly, rather than having caller test rule sign. This avoids
22103 some unnecessary tests.
22104 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
22105 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
22106 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
22108 * xfont.c (xfont_text_extents): Remove var that was set but not used.
22109 (xfont_open): Avoid unnecessary tests.
22111 * composite.c (composition_gstring_put_cache): Use unsigned integer.

22120 by using the new macro.
22122 * textprop.c (set_text_properties_1): Change while to do-while,
22123 since the condition is always true at first.
22125 * intervals.c (graft_intervals_into_buffer): Mark var as used.
22126 (interval_deletion_adjustment): Return unsigned value.
22129 * process.c (list_processes_1, create_pty, read_process_output):
22130 (exec_sentinel): Remove vars that were set but not used.
22131 (create_pty): Remove unnecessary "volatile"s.

22156 * eval.c (funcall_lambda): Rename local to avoid shadowing.
22158 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
22159 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
22160 can always succeed if overflow has undefined behavior.

22163 (wordify): Omit three unnecessary tests.
22165 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
22166 All callers changed. This avoids the need for an unused var.
22168 * casefiddle.c (casify_region): Remove var that is set but not used.
22170 * dired.c (file_name_completion): Remove var that is set but not used.
22172 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
22174 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
22175 (Finsert_file_contents): Remove unnecessary code checking fd.
22177 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
22178 Check for integer overflow on size calculations.
22180 * buffer.c (Fprevious_overlay_change): Remove var that is set
22183 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
22184 Remove vars that are set but not used.
22185 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
22186 (timer_check_2): Mark vars as initialized.
22188 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
22190 * image.c (lookup_image): Remove var that is set but not used.
22191 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
22193 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
22194 that are set but not used.
22196 * xfns.c (make_invisible_cursor): Don't return garbage
22197 if XCreateBitmapFromData fails (Bug#8410).
22199 * xselect.c (x_get_local_selection, x_handle_property_notify):
22200 Remove vars that are set but not used.
22202 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
22203 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
22205 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
22206 Remove var that is set but not used.
22207 (scroll_bar_windows_size): Now size_t, not int.
22208 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
22209 Check for overflow.
22211 * xfaces.c (realize_named_face): Remove vars that are set but not used.
22212 (map_tty_color) [!defined MSDOS]: Likewise.
22214 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
22216 * coding.c: Remove vars that are set but not used.
22217 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
22218 All callers changed.
22219 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
22220 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
22221 (decode_coding_charset): Remove vars that are set but not used.
22223 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
22224 that is set but not used.
22226 * print.c (print_object): Remove var that is set but not used.
22228 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
22229 The gnulib version avoids calling malloc in the usual case,
22230 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
22231 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
22232 * filelock.c (current_lock_owner): Likewise.
22233 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
22234 * sysdep.c: Include allocator.h, careadlinkat.h.
22235 (emacs_no_realloc_allocator): New static constant.
22236 (emacs_readlink): New function.
22237 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
22238 ../lib/careadlinkat.h.
22240 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
22242 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
22243 first non-nil return value).

22257 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
22258 and thereabouts. All callers changed.
22259 (get_per_char_metric): Remove parameter `f', unused since
22260 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
22262 2011-04-02 Jim Meyering <meyering@redhat.com>
22264 do not dereference NULL upon failed strdup
22265 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
22266 (ns_get_family): Likewise.
22268 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
22270 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
22272 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
22274 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
22277 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
22279 Add lexical binding.
22281 * window.c (Ftemp_output_buffer_show): New fun.
22282 (Fsave_window_excursion):
22283 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
22285 * lread.c (lisp_file_lexically_bound_p): New function.
22286 (Fload): Bind Qlexical_binding.
22287 (readevalloop): Remove `evalfun' arg.
22288 Bind Qinternal_interpreter_environment.
22289 (Feval_buffer): Bind Qlexical_binding.
22290 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
22292 (syms_of_lread): Declare `lexical-binding'.
22294 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
22296 * keyboard.c (eval_dyn): New fun.
22297 (menu_item_eval_property): Use it.
22299 * image.c (parse_image_spec): Use Ffunctionp.
22301 * fns.c (concat, mapcar1): Accept byte-code-functions.
22303 * eval.c (Fsetq): Handle lexical vars.
22304 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
22305 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
22306 (FletX, Flet): Obey lexical binding.
22307 (Fcommandp): Handle closures.
22308 (Feval): New `lexical' arg.
22309 (eval_sub): New function extracted from Feval. Use it almost
22310 everywhere where Feval was used. Look up vars in lexical env.
22312 (Ffunctionp): Move from subr.el.
22313 (Ffuncall): Handle closures.
22314 (apply_lambda): Remove `eval_flags'.
22315 (funcall_lambda): Handle closures and new byte-code-functions.
22316 (Fspecial_variable_p): New function.
22317 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
22318 but without exporting it to Lisp.
22320 * doc.c (Fdocumentation, store_function_docstring):
22321 * data.c (Finteractive_form): Handle closures.
22323 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
22326 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
22328 (exec_byte_code): New function extracted from Fbyte_code to handle new
22329 calling convention for byte-code-functions. Add new byte-codes.
22331 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
22333 * alloc.c (Fmake_symbol): Init new `declared_special' field.
22335 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22337 * xdisp.c (redisplay_internal): Fix prototype.
22339 2011-03-31 Eli Zaretskii <eliz@gnu.org>
22341 * xdisp.c (SCROLL_LIMIT): New macro.
22342 (try_scrolling): Use it when setting scroll_limit.
22343 Limit scrolling to 100 screen lines.
22344 (redisplay_window): Even when falling back on "recentering",
22345 position point in the window according to scroll-conservatively,
22346 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
22348 (try_scrolling): When point is above the window, allow searching
22349 as far as scroll_max, or one screenful, to compute vertical
22350 distance from PT to the scroll margin position. This prevents
22351 try_scrolling from unnecessarily failing when
22352 scroll-conservatively is set to a value slightly larger than the
22353 window height. Clean up the case of PT below the margin at bottom
22354 of window: scroll_max can no longer be INT_MAX. When aggressive
22355 scrolling is in use, don't let point enter the opposite scroll
22356 margin as result of the scroll.
22357 (syms_of_xdisp) <scroll-conservatively>: Document the
22358 threshold of 100 lines for never-recentering scrolling.
22360 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22362 * dispextern.h (move_it_by_lines):
22363 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

22365 (message_log_check_duplicate): Remove parameters `prev_bol' and
22366 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22367 (redisplay_internal): Remove parameter `preserve_echo_area',
22368 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
22370 * indent.c (Fvertical_motion):
22371 * window.c (window_scroll_pixel_based, Frecenter):
22372 Don't pass `need_y_p' to `move_it_by_lines'.
22374 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
22376 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
22377 steal a few bits to be more compact.
22378 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
22379 Remove unneeded casts.
22381 * bytecode.c (Fbyte_code): CAR and CDR can GC.
22383 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
22385 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
22386 binding" message (bug#7967).
22388 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
22390 Fix more problems found by GCC 4.6.0's static checks.
22392 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
22393 Remove unused local var.
22395 * editfns.c (Fmessage_box): Remove unused local var.
22397 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
22398 (note_mode_line_or_margin_highlight, note_mouse_highlight):
22399 Omit unused local vars.
22400 * window.c (shrink_windows): Omit unused local var.
22401 * menu.c (digest_single_submenu): Omit unused local var.
22402 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
22403 Omit unused local var.
22405 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
22406 Don't assume string length fits in int.
22407 (keyremap_step, read_key_sequence): Use size_t for sizes.
22408 (read_key_sequence): Don't check last_real_key_start redundantly.
22410 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
22411 instead of alloca (Bug#8344).
22413 * eval.c (Fbacktrace): Don't assume nargs fits in int.
22414 (Fbacktrace_frame): Don't assume nframes fits in int.
22416 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
22418 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
22421 * term.c (produce_glyphless_glyph): Remove unnecessary test.
22423 * cm.c (calccost): Turn while-do into do-while, for clarity.
22425 * keyboard.c (syms_of_keyboard): Use the same style as later
22426 in this function when indexing through an array. This also
22427 works around GCC bug 48267.
22429 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
22431 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
22433 * chartab.c (sub_char_table_ref_and_range): Redo for slight
22434 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
22436 * keyboard.c, keyboard.h (num_input_events): Now size_t.
22437 This avoids undefined behavior on integer overflow, and is a bit
22438 more convenient anyway since it is compared to a size_t variable.
22440 Variadic C functions now count arguments with size_t, not int.
22441 This avoids an unnecessary limitation on 64-bit machines, which
22442 caused (substring ...) to crash on large vectors (Bug#8344).
22443 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
22444 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

22452 * fns.c (concat): Likewise.
22453 * frame.c (x_set_frame_parameters): Likewise.
22454 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
22455 0 if not found, not -1. All callers changed.
22457 * alloc.c (garbage_collect): Don't assume stack size fits in int.
22458 (stack_copy_size): Now size_t, not int.
22459 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
22461 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
22463 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
22464 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
22465 All callers changed.
22467 * lisp.h (multibyte_char_to_unibyte):
22468 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
22469 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

22480 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
22481 don't set the hook to nil, but remove the offending function instead.
22482 (Qcommand_hook_internal): Remove, unused.
22483 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
22484 Vcommand_hook_internal.
22486 * eval.c (enum run_hooks_condition): Remove.
22487 (funcall_nil, funcall_not): New functions.
22488 (run_hook_with_args): Call each function through a `funcall' argument.

22502 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
22503 All callers changed.
22505 * w32.c (_wsa_errlist): Use braces for struct initializers.
22507 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

22623 Remove unused variable `width'.
22625 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
22627 * w32term.c (x_set_glyph_string_clipping):
22628 Don't pass uninitialized region to CombineRgn.

22652 2011-03-23 Julien Danjou <julien@danjou.info>
22654 * term.c (Fsuspend_tty, Fresume_tty):
22655 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
22656 * window.c (temp_output_buffer_show):
22657 * insdel.c (signal_before_change):
22658 * frame.c (Fhandle_switch_frame):

22663 * callint.c (Fcall_interactively):
22664 * buffer.c (Fkill_all_local_variables):
22665 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22667 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22668 unconditionally since it does the check itself.
22670 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22672 Fix more problems found by GCC 4.5.2's static checks.
22674 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22675 the first time through the loop, since we know p0 < p1 then.
22676 This also avoids a gcc -Wstrict-overflow warning.
22678 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22679 leading to a memory leak, possible in functions like
22680 load_charset_map_from_file that can allocate an unbounded number
22681 of objects (Bug#8318).
22683 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22684 that could (at least in theory) be that large.
22686 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22687 This is less likely to overflow, and avoids undefined behavior if
22688 overflow does occur. All callers changed. Use strtoul to scan
22689 for the unsigned long integer.
22690 (pint2hrstr): Simplify and tune code slightly.
22691 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
22693 * scroll.c (do_scrolling): Work around GCC bug 48228.
22694 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

22699 This also avoids a warning with gcc -Wstrict-overflow.
22701 * fileio.c (Fcopy_file): Report error if fchown or fchmod
22704 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
22706 * process.c (Fmake_network_process): Use socklen_t, not int,
22707 where POSIX says socklen_t is required in portable programs.
22708 This fixes a porting bug on hosts like 64-bit HP-UX, where
22709 socklen_t is wider than int (Bug#8277).
22710 (Fmake_network_process, server_accept_connection):
22711 (wait_reading_process_output, read_process_output):
22714 * process.c: Rename or move locals to avoid shadowing.

22724 Make tparam.h and terminfo.c consistent.
22725 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22726 Include tparam.h instead, since it declares them.
22727 * cm.h (PC): Remove extern decl; tparam.h now does this.
22728 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22729 * terminfo.c: Include tparam.h, to check interfaces.
22730 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22731 (tparam): Adjust signature to match interface in tparam.h;
22732 this removes some undefined behavior. Check that outstring and len
22733 are zero, which they always are with Emacs.
22734 * tparam.h (PC, BC, UP): New extern decls.
22736 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22737 (xftfont_open): Rename locals to avoid shadowing.
22739 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
22740 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
22741 (OTF_TAG_SYM): Omit macro if not needed.

22749 * xml.c (make_dom): Now static.
22751 * composite.c (composition_compute_stop_pos): Rename local to
22753 (composition_reseat_it): Remove unused locals.
22754 (find_automatic_composition, composition_adjust_point): Likewise.
22755 (composition_update_it): Mark var as initialized.
22756 (find_automatic_composition): Mark vars as initialized,
22757 with a FIXME (Bug#8290).

22760 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
22761 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
22762 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
22763 (BUF_DEC_POS): Be more systematic about renaming local temporaries
22764 to avoid shadowing.
22766 * textprop.c (property_change_between_p): Remove; unused.
22768 * intervals.c (interval_start_pos): Now static.
22770 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

22773 Rename locals to avoid shadowing.
22775 * sound.c (wav_play, au_play, Fplay_sound_internal):
22776 Fix pointer signedness.
22777 (alsa_choose_format): Remove unused local var.
22778 (wav_play): Initialize a variable to 0, to prevent undefined
22779 behavior (Bug#8278).
22781 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22783 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22785 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22786 clobbering (Bug#8298).
22787 * sysdep.c (sys_subshell): Likewise.
22788 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22790 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22791 This should get cleaned up, so that child_setup has the
22792 same signature on all platforms.
22794 * callproc.c (call_process_cleanup): Now static.
22795 (relocate_fd): Rename locals to avoid shadowing.
22797 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
22799 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
22800 not to be necessary, and produces flickering.
22802 2011-03-20 Glenn Morris <rgm@gnu.org>
22804 * config.in: Remove file.
22806 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
22808 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
22809 are now in src/globals.h.
22810 (syms_of_minibuf): Remove spurious & from previous change.
22812 2011-03-20 Leo Liu <sdl.web@gmail.com>
22814 * minibuf.c (completing-read-function): New variable.
22815 (completing-read-default): Rename from completing-read.
22816 (completing-read): Call completing-read-function.
22818 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
22820 * xfaces.c (Fx_load_color_file):
22821 Read color file from absolute filename (bug#8250).
22823 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
22825 * makefile.w32-in: Update dependencies.
22827 2011-03-17 Eli Zaretskii <eliz@gnu.org>
22829 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

22836 (sigchld_handler): Now static.
22838 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
22839 That way, the code declares only the vars that it needs.
22840 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
22841 * s/cygwin.h (PTY_ITERATION): Likewise.
22842 * s/darwin.h (PTY_ITERATION): Likewise.

22846 * process.c (allocate_pty): Don't declare stb unless it's needed.
22848 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
22849 (CONSTANTLIM): Remove; unused.
22850 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
22851 Define only if needed.
22853 * unexelf.c (unexec): Name an expression,
22854 to avoid gcc -Wbad-function-cast warning.
22855 Use a different way to cause a compilation error if anyone uses
22856 n rather than nn, a way that does not involve shadowing.
22857 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
22859 * deps.mk (unexalpha.o): Remove; unused.
22861 New file unexec.h, the (simple) interface for unexec (Bug#8267).
22862 * unexec.h: New file.
22863 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
22864 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
22865 Depend on unexec.h.
22866 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
22867 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
22868 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
22869 Change as necessary to match prototype in unexec.h.
22871 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
22873 (back_comment, skip_chars): Mark vars as initialized.
22875 * character.h (FETCH_STRING_CHAR_ADVANCE_NO_CHECK, BUF_INC_POS):

22887 instead of using an uninitialized var.
22888 (font_sort_entities): Mark var as initialized.
22890 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
22892 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

22904 * floatfns.c (domain_error2): Define only if needed.
22905 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
22907 * alloc.c (mark_backtrace): Move decl from here ...
22908 * lisp.h: ... to here, so that it can be checked.
22910 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
22911 (Fdefvar): Rewrite so as not to use empty "else".

22916 * callint.c (quotify_arg, quotify_args): Now static.
22917 (Fcall_interactively): Rename locals to avoid shadowing.
22918 Use const pointer when appropriate.
22920 * lisp.h (get_system_name, get_operating_system_release):
22921 Move decls here, to check interfaces.
22922 * process.c (get_operating_system_release): Move decl to lisp.h.
22923 * xrdb.c (get_system_name): Likewise.
22924 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
22925 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
22926 some of which prompt warnings from gcc -Wbad-function-cast.
22927 (Fformat_time_string, Fencode_time, Finsert_char):
22928 (Ftranslate_region_internal, Fformat):
22929 Rename or remove local vars to avoid shadowing.
22930 (Ftranslate_region_internal): Mark var as initialized.
22932 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
22935 * lisp.h (eassert): Check that the argument compiles, even if
22936 ENABLE_CHECKING is not defined.
22938 * data.c (Findirect_variable): Name an expression, to avoid
22939 gcc -Wbad-function-cast warning.
22940 (default_value, arithcompare, arith_driver, arith_error): Now static.

22948 Rename locals to avoid shadowing.
22949 (mark_stack): Move local variables into the #ifdef region where
22951 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
22952 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
22954 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
22955 (GC_STRING_CHARS): Remove; not used.
22956 (Fmemory_limit): Cast sbrk's returned value to char *.
22958 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
22959 avoids undefined behavior in theory.
22961 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
22963 Use functions, not macros, for up- and down-casing (Bug#8254).
22964 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22965 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
22966 to use the following functions instead of these macros.
22967 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
22968 EMACS_INT, since callers assume the returned value fits in int.
22969 (upcase1): Likewise, for UPCASE_TABLE.
22970 (uppercasep, lowercasep, upcase): New static inline functions.
22971 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
22972 the race-condition problem in the old DOWNCASE.
22974 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
22975 Rename locals to avoid shadowing.
22976 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
22977 (regex_compile, re_search_2, re_match_2_internal):
22978 Remove unused local vars.
22979 (FREE_VAR): Rewrite so as not to use empty "else",
22980 which gcc can warn about.
22981 (regex_compile, re_match_2_internal): Mark locals as initialized.
22982 (RETALLOC_IF): Define only if needed.
22983 (WORDCHAR_P): Likewise. This one is never needed, but is used
22984 only in a comment talking about a compiler bug, so put inside
22985 the #if 0 of that comment.
22986 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22987 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
22990 * search.c (boyer_moore): Rename locals to avoid shadowing.
22991 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
22992 (PREV_CHAR_BOUNDARY): Likewise.
22994 * search.c (simple_search): Remove unused var.
22996 * dired.c (compile_pattern): Move decl from here ...

23002 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
23004 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
23005 Rename locals to avoid shadowing.
23006 (Fvertical_motion): Mark locals as initialized.
23008 * casefiddle.c (casify_object, casify_region): Now static.
23009 (casify_region): Mark local as initialized.
23011 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
23013 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
23014 New macros, so that the caller can use some names other than
23015 gcpro1, gcpro2, etc.
23016 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
23018 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
23019 argument, for consistency with GCPRO2_VAR, etc: it is now the
23020 prefix of the variable, not the variable itself. All uses
23022 * dired.c (directory_files_internal, file_name_completion):
23023 Rename locals to avoid shadowing.
23025 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
23026 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
23027 dired.c's scmp function, had undefined behavior.
23028 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23029 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
23030 * buffer.h: ... to here, because these macros use current_buffer,
23031 and the new implementation with inline functions needs to have
23032 current_buffer in scope now, rather than later when the macros
23034 (downcase, upcase1): New static inline functions.
23035 (DOWNCASE, UPCASE1): Reimplement using these functions.
23036 This avoids undefined behavior in expressions like
23037 DOWNCASE (x) == DOWNCASE (y), which previously suffered
