92 * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW
93 to avoid deleted windows. Use contents slot instead of buffer.
94 * buffer.c, dispextern.h, editfns.c, fileio.c, font.c, fringe.c:
95 * indent.c, insdel.c, keyboard.c, keymap.c, minibuf.c, msdos.c:
96 * nsfns.m, nsmenu.m, nsterm.m, print.c, w32fns.c, w32menu.c, xfaces.c:

474 and just not using it.)
476 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
478 File synchronization fixes (Bug#13944).
479 * Makefile.in (LIB_FDATASYNC): New macro.
481 * conf_post.h (BSD_SYSTEM, BSD_SYSTEM_AHB): Remove; no longer needed.
482 * fileio.c (Fwrite_region, write_region_inhibit_fsync):
483 Don't worry about HAVE_FSYNC, since a substitute fsync is
484 available if the system lacks one.
485 (Fwrite_regin): Retry fsync if interrupted.
487 2013-03-13 Eli Zaretskii <eliz@gnu.org>
489 * w32term.c (w32_read_socket): If the Emacs frame is being
490 activated, call w32fullscreen_hook, to make sure the new frame
491 dimensions are in effect. (Bug#13937)
493 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
495 * xdisp.c (init_iterator): Simplify because both character and byte
496 positions are either specified or -1. Add eassert. Adjust comment.
497 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
498 character and byte positions can be obtained from marker.

515 a function pointer type; the C Standard requires this.
517 * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
518 Include <sys/param.h> unconditionally, as that works elsewhere and
519 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
520 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
523 2013-03-11 Paul Eggert <eggert@cs.ucla.edu>

552 common file dialog code.
554 * w32fns.c (Ffile_system_info): Remove from cygw32 builds, which
555 can just use du like other systems.

599 * insdel.c (adjust_after_replace): Make it public. New arg
601 (adjust_after_insert): Call adjust_after_replace with the new arg
604 2013-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
606 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
607 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
608 from Elisp via unread-command-events.
610 * keyboard.c (access_keymap_keyremap): Accept nil return value from
611 functions to mean "no change".
613 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
615 region-cache.c, scroll.c, search.c: Use bool for booleans.
616 * lisp.h (compile_pattern):
617 * scroll.c (do_scrolling, do_direct_scrolling):
618 * search.c (struct regexp_cache, compile_pattern_1)
619 (compile_pattern, string_match_1, search_command)
620 (trivial_regexp_p, search_buffer, Freplace_match, match_limit)
621 (search_regs_saved, Fregexp_quote):
622 Use bool for boolean.
623 * region-cache.c (region_cache_forward, region_cache_backward):
624 Fix comments to match code: these functions return int, not boolean.
626 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
628 * search.c (find_newline): Accept start and end byte positions
629 as arguments and allow -1 if not known.

631 * lisp.h (find_newline, find_newline_no_quit): Adjust prototype.
632 * bidi.c (bidi_find_paragraph_start): Pass byte position to

635 Adjust call to find_newline.
636 * indent.c (vmotion): Adjust calls to find_newline_no_quit.

639 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
640 (get_visually_first_element, move_it_vertically_backward): Likewise.
641 Obtain byte position from the display iterator, where appropriate.
643 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>

661 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
663 * bidi.c (bidi_fetch_char): Swap first and second arguments
664 to match other functions accepting character and byte positions.
666 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.
667 (bidi_paragraph_init): Likewise. Use DEC_BOTH which is faster
668 when you need just to move to the previous buffer position.
669 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
671 2013-03-07 Eli Zaretskii <eliz@gnu.org>
673 * .gdbinit (prowlims): Display the enabled_p flag of the row.
675 2013-03-07 Dmitry Antipov <dmantipov@yandex.ru>

690 (Frecenter): Adjust calls to vmotion.
692 2013-03-07 Dmitry Antipov <dmantipov@yandex.ru>
694 * lisp.h (list2i, list3i): New functions.

739 (ALLOC_CONVERSION_WORK_AREA): Use SAFE_ALLOCA.
740 (decode_coding, encode_coding): Add USE_SAFE_ALLOCA and SAFE_FREE.

744 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
746 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
747 * sysdep.c (list_system_processes)
748 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
749 Make it a stub in this case; otherwise the build might fail,
750 and this code hasn't been tested on such hosts anyway.
751 Problem reported by Nelson H. F. Beebe in
752 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
753 and analyzed by Jérémie Courrèges-Anglas in
754 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
756 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
758 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
759 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
760 (get_visually_first_element, move_it_vertically_backward): Ajust users.
761 * bidi.c (bidi_find_paragraph_start): Likewise.
762 * indent.c (vmotion): Likewise.
764 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
766 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
767 * filelock.c: Include <c-ctype.h>.
768 (MAX_LFINFO): New top-level constant.
769 (lock_info_type): Remove members pid, boot_time. Add members at,
770 dot, colon. Change user member to be the entire buffer, not a
771 pointer. This allows us to handle the case where a foreign
772 pid or boot time exceeds the local range. All uses changed.
773 (LINKS_MIGHT_NOT_WORK): New constant.
774 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
775 (defined_WINDOWSNT): Remove.
776 (MAKE_LOCK_NAME, file_in_lock_file_name):
777 Always use .#FILE (not .#-FILE) for the file lock,
778 even if it is a regular file.
779 (rename_lock_file): New function.
780 (create_lock_file): Use it.
781 (create_lock_file, read_lock_data):
782 Prefer a symbolic link for the lock file, falling back on a
783 regular file if symlinks don't work. Do not try to create
784 symlinks on MS-Windows, due to security hassles. Stick with
785 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
786 link, rename, unlink, mkstemp) when creating locks, as a GNUish
787 host may be using a Windowsish file system, and cannot use
788 MS-Windows-only system calls. Fall back on mktemp if mkstemp
789 doesn't work. Don't fail merely because of a symlink-contents
790 length limit in the current file system; fall back on regular
791 files. Increase the symlink contents length limit to 8 KiB, this
792 should be big enough for any real use and doesn't crunch the
794 (create_lock_file, lock_file_1, read_lock_data):
795 Simplify allocation of lock file buffers now that they fit in 8 KiB.
796 (lock_file_1): Return error number, not bool. All callers changed.
797 (ELOOP): New macro, if not already defined.
798 (read_lock_data): Return size of lock file contents, not Lisp object.
799 All callers changed. Handle a race condition if some other process
800 replaces a regular-file lock with a symlink lock or vice versa,
801 while we're trying to read the lock.
802 (current_lock_owner): Parse contents more carefully, to help avoid
803 confusing a regular-file lock with some other application's use
804 of the file. Check for lock file contents being too long, or
805 not parsing correctly.
806 (current_lock_owner, lock_file):
807 Allow foreign pid and boot times that exceed the local range.
808 (current_lock_owner, lock_if_free, lock_file):
809 Simplify allocation of lock file contents.
810 * w32.c (sys_rename_replace): New function, containing most of
811 the contents of the old sys_rename.
812 (sys_rename): Use it.
813 (fchmod): New dummy function.
814 * w32.h (sys_rename_replace, fchmod): New decls.
816 2013-03-05 Eli Zaretskii <eliz@gnu.org>
818 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
819 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
820 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
821 <dmantipov@yandex.ru>.
823 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
825 * composite.c (get_composition_id, fill_gstring_header):
826 Use make_uninit_vector where appropriate.
827 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
828 * xselect.c (clean_local_selection_data): Likewise.
830 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
832 Fix misuse of ImageMagick that caused core dump (Bug#13846).
833 * image.c (imagemagick_load_image): Calculate height and width
834 after flattening the image, not before.
836 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
838 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
839 * ftfont.c (ftfont_shape_by_flt): Likewise.
840 * w32uniscribe.c (uniscribe_shape): Likewise.
842 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
844 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
845 The old approach, which fell back on DIR/.#FILE.0 through
846 DIR/.#FILE.9, had race conditions that could not be easily fixed.
847 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
848 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
849 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
850 because the locking mechanism was never reliable in that case).
851 This patch fixes this and other bugs discovered by a code
852 inspection that was prompted by
853 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
854 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
855 to avoid interoperability problems between the MS-Windows and
856 non-MS-Windows implementations. MS-Windows and non-MS-Windows
857 instances of Emacs now ignore each others' locks.
858 * filelock.c (defined_WINDOWSNT): New constant.
859 (MAKE_LOCK_NAME, fill_in_lock_file_name):
860 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
861 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
862 regular files on MS-Windows hosts.
863 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
864 Use SAFE_ALLOCA to avoid problems with long file names.
865 (MAX_LFINFO): Now a local constant, not a global macro.
866 (IS_LOCK_FILE): Remove.
867 (lock_file_1): Don't inspect errno if symlink call succeeds;
869 (lock_file): Document that this function can return if lock
871 (lock_file): Don't access freed storage.
873 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>

877 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
879 * textprop.c: Use bool for booleans.
880 (validate_interval_range, Fadd_text_properties)
881 (Fremove_text_properties): Prefer bool to int when either works.
883 2013-03-02 Eli Zaretskii <eliz@gnu.org>
885 * textprop.c (Fadd_text_properties, Fremove_text_properties):
886 If the interval tree changes as a side effect of calling
887 modify_region, re-do processing starting from the call to
888 validate_interval_range. (Bug#13743)
890 2013-02-28 Eli Zaretskii <eliz@gnu.org>
892 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
895 2013-02-27 Eli Zaretskii <eliz@gnu.org>
897 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
898 _SH_DENYRW flag, instead of emacs_open, to deny any other process
899 access to the lock file until it is written and closed.
902 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
904 * callint.c (Qcall_interactively):
905 * macros.c (Qexecute_kbd_macro):

910 * window.c (Frecenter): Tiny docstring enhancement.
912 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
914 Minor textprop integer cleanup.
915 * intervals.h, textprop.c (add_text_properties_from_list):
916 Return void, not int, since nobody uses the return value.
917 * textprop.c (validate_plist, add_properties, remove_properties)
918 (Fadd_text_properties):
919 Don't assume list length fits in int.
920 (interval_has_all_properties, interval_has_some_properties)
921 (interval_has_some_properties_list, add_properties, remove_properties)
922 (Fadd_text_properties, Fremove_text_properties)
923 (Fremove_list_of_text_properties, text_property_stickiness):
924 Use bool for booleans.
925 (Fadd_text_properties, Fremove_text_properties):
926 (Fremove_list_of_text_properties):
927 Reindent do-while as per GNU style.
929 2013-02-25 Eli Zaretskii <eliz@gnu.org>
931 Implement CLASH_DETECTION for MS-Windows.
933 * filelock.c [WINDOWSNT]: Include w32.h.
934 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
935 function of that name. Up-case the macro arguments.
936 (IS_LOCK_FILE): New macro.
937 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
938 (create_lock_file): New function, with body extracted from
940 [WINDOWSNT]: Implement lock files by writing a regular file with
941 the lock information as its contents.
942 (read_lock_data): New function, on Posix platforms just calls
944 [WINDOWSNT]: Read the lock info from the file.
945 (current_lock_owner): Call read_lock_data instead of calling
946 emacs_readlinkat directly.
947 (lock_file) [WINDOWSNT]: Run the file name through
950 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
951 just check if the process by that PID exists.
953 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
954 also present, as doing so will fail to error out if the file
957 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
959 * textprop.c (Fadd_text_properties, Fremove_text_properties)
960 (Fremove_list_of_text_properties): Skip all of the intervals in
961 the region between START and END that already have resp. don't
962 have the requested properties, not just the first one.
963 Add assertions that the loop afterwards always modifies the
964 properties. (Bug#13743)
966 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
968 * callint.c (Fcall_interactively): Use the right lexical environment

976 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
977 (START_FILES): Remove. All uses removed.
978 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
979 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
980 (buildobj.h): Use it.
981 ($(ALLOBJS)): Depend on globals.h.
982 (temacs$(EXEEXT)): Use $(ALLOBJS).
983 * autodeps.mk (ALLOBJS): Move to Makefile.in.
984 * deps.mk (vm-limit.o):
985 * makefile.w32-in ($(BLD)/vm-limit.$(O)):

993 (make_hdr): Use DATA_START instead of start_of_data.
994 * vm-limit.c: Move most of mem-limits.h's contents here.
995 (data_start): New decl. It's OK if this is approximate,
996 so simplify-away some unnecessary exactness.
997 (POINTER): Remove; all uses removed.
998 (data_space_start): Now char *, to avoid casts.
999 (exceeds_lisp_ptr): New function, replacing the old
1000 EXCEEDS_LISP_PTR macro. All uses changed.
1001 (check_memory_limits): Simplify and remove casts.
1002 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.

1019 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
1021 Assume C89 or better.
1022 * ralloc.c (SIZE, POINTER, NIL):
1023 * vm-limit.c (POINTER):
1024 Remove, replacing all uses with C89 equivalents. These old
1025 symbols were present only for porting to pre-C89 platforms.
1027 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
1029 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
1030 This avoids warning messages reported as part of Bug#13546.
1032 2013-02-21 Ken Brown <kbrown@cornell.edu>
1034 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.

1045 2013-02-19 Daniel Colascione <dancol@dancol.org>
1047 * sheap.c (report_sheap_usage): Use message, not message1, so
1048 that we don't try to create a buffer while we're in the middle
1049 of dumping Emacs. Explain why.
1051 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
1053 * search.c (find_newline): Return byte position in bytepos.

1066 2013-02-19 Eli Zaretskii <eliz@gnu.org>
1068 * w32proc.c (new_child): Avoid leaking handles if the subprocess
1069 resources were not orderly released.
1071 2013-02-17 Eli Zaretskii <eliz@gnu.org>
1073 * xdisp.c (x_draw_vertical_border): For a window that is neither
1074 the leftmost nor the rightmost, redraw both the left and the right
1075 vertical borders. (Bug#13723)

1100 unconditionally. (Bug#9066)
1102 * w32.c (set_errno): Reset h_errno and don't set it to any other
1103 value. Set errno instead.
1104 (check_errno): Reset h_errno.
1105 (sys_socket, socket_to_fd, sys_bind, sys_connect)
1106 (sys_gethostname, sys_getservbyname, sys_getpeername)
1107 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
1108 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set

1112 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1114 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
1116 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1118 * keyboard.c (read_char): Fix calculation of auto-save time out
1119 when auto-save-timeout is less than 4. (Bug#13720)
1121 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
1122 time. Improve diagnostics in DebPrint. (Bug#13546)

1130 value that is out of bounds.
1131 (sys_accept): If fd is negative, do not set up the child_process

1148 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1150 Fix AIX port (Bug#13650).
1151 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
1152 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
1153 was #undeffed earlier, so it cannot be used as a macro here.
1154 Use the constant and not the macro.
1156 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1158 * w32proc.c (new_child): If no vacant slots are found in
1159 child_procs[], make another pass looking for slots whose process
1160 has exited or died. (Bug#13546)
1162 * w32.c (sys_pipe): When failing due to file descriptors above
1163 MAXDESC, set errno to EMFILE.
1164 (_sys_read_ahead): Update cp->status when failing to read serial
1165 communications input, so that the status doesn't stay at
1166 STATUS_READ_IN_PROGRESS. (Bug#13546)
1168 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
1170 * gtkutil.c (tb_size_cb): New function.
1171 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
1173 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
1175 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
1178 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
1180 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
1182 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>

1188 Break long line. Remove useless prototype and format comment.
1190 2013-02-13 Glenn Morris <rgm@gnu.org>
1192 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
1194 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1196 Improve AIX port some more (Bug#13650).
1197 With this, it should be as good as it was in 23.3, though it's
1198 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
1199 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
1200 * unexaix.c (start_of_text): Remove.
1201 (_data, _text): Declare as char[], not int, as AIX manual suggests.
1202 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
1203 (orig_load_scnptr, orig_data_scnptr):
1204 Now off_t, not long, since they are file offsets.
1205 (make_hdr): Use _data, not start_of_data ().
1206 This is the key part of the fix.
1207 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
1208 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
1210 * pre-crt0.c (data_start): Initialize to 1.
1211 This ports to compilers that optimize the external declaration
1212 'int x = 0;' as if it were 'int x;' to shrink the executable.
1214 Improve AIX port (Bug#13650).
1215 This doesn't fix the bug, but it makes progress: Emacs builds now.
1216 * unexaix.c: Include inttypes.h, stdarg.h.
1217 (report_error, report_error_1): Mark as _Noreturn.
1218 (report_error): Don't report the wrong errno.
1219 (report_error_1): Now varargs. All callers changed.
1220 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
1221 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
1222 (write_ptr): Use %p to print address rather than %lx and a cast
1223 to unsigned long. Grow buffer a bit, to be safer.
1225 2013-02-13 Eli Zaretskii <eliz@gnu.org>
1227 * bidi.c (bidi_resolve_neutral): After finding the next
1228 non-neutral character, accept NEUTRAL_ON type as well, because
1229 directional control characters, such as LRE and RLE, have their
1230 type converted to that by bidi_resolve_weak. This avoids aborts
1231 when LRE/RLE follows a run of neutrals.
1232 (bidi_move_to_visually_next): Assert that return value of
1233 bidi_peek_at_next_level is non-negative. Negative values will
1236 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1238 Minor getenv-related fixes.
1239 * callproc.c (Fcall_process_region) [!DOS_NT]:
1240 Avoid unnecessary duplicate call to getenv.
1241 * callproc.c (init_callproc):
1242 * dispnew.c (init_display):
1243 * sysdep.c (sys_subshell):
1244 Omit unnecessary cast of getenv or egetenv.
1246 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
1248 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
1249 Update dependencies.
1251 2013-02-12 Eli Zaretskii <eliz@gnu.org>
1253 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
1255 (display_line): Set w->region_showing to the value of
1256 it->region_beg_charpos, not to -1. This fixes redisplay
1257 optimization when cursor is moved up after M->. (Bug#13623)
1259 (try_scrolling): Scroll text up more if point is too close to ZV
1260 and inside the scroll margin. This makes sure point is moved
1261 outside the scroll margin in these cases.
1263 * window.h (struct window): region_showing can no longer be
1266 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
1268 Tune by using memchr and memrchr.
1269 * doc.c (Fsnarf_documentation):
1270 * fileio.c (Fsubstitute_in_file_name):
1271 * search.c (find_newline, scan_newline):
1272 * xdisp.c (pos_visible_p, display_count_lines):
1273 Use memchr and memrchr rather than scanning byte-by-byte.
1274 * search.c (find_newline): Rename from scan_buffer.
1275 Omit first arg TARGET, as it's always '\n'. All callers changed.
1277 Clean up read_key_sequence a tiny bit more.
1278 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
1279 (read_key_sequence): Remove unused locals.
1281 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
1283 Clean up read_key_sequence a bit; reread active keymaps after first event.
1284 * keyboard.c (read_char, read_char_x_menu_prompt)
1285 (read_char_minibuf_menu_prompt):
1286 Replace nmaps+maps with a single `map' arg.
1287 (follow_key): Operate on a single map.
1288 (active_maps): New function.
1289 (test_undefined): Also return true for nil bindings.
1290 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
1291 a single (composed) keymap. Remember `first_event' to choose the right
1292 set of active keymaps. Recompute the set of keymaps after receiving
1293 the first event. Remove GOBBLE_FIRST_EVENT.
1294 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
1295 * keyboard.h (read_char): Update declaration.
1296 * lread.c (read_filtered_event): Adjust call to read_char.
1298 2013-02-11 Eli Zaretskii <eliz@gnu.org>
1300 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1301 Don't use the limitation on backwards movement when lines are truncated
1302 in the window. (Bug#13675)
1304 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
1306 * marker.c (set_marker_internal): If desired position is passed
1307 as a marker, avoid call to buf_charpos_to_bytepos.
1308 * window.c (Fset_window_point): Omit redundant type checking.
1309 (Fset_window_start): Likewise. Format comment.
1310 (window_scroll_pixel_based): Use set_marker_restricted_both
1311 with character and byte positions obtained from an iterator.
1312 (Fset_window_configuration): Use set_marker_restricted_both.
1313 * xdisp.c (message_dolog): Likewise.
1315 2013-02-10 Eli Zaretskii <eliz@gnu.org>
1317 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1318 When text lines are longer than window's screen lines, don't move back
1319 too far. This speeds up some redisplay operations. (Bug#13675)
1321 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
1323 * syntax.c (scan_sexps_forward): Fix byte position calculation
1324 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
1326 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
1328 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
1329 that was not needed.
1331 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
1333 Minor hashing refactoring.
1334 * fns.c (SXHASH_REDUCE): Move to lisp.h.
1335 (sxhash_float): Return EMACS_UINT, for consistency with the other
1337 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
1338 non-static inline function and therefore can't use static vars.
1339 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
1340 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
1341 with the other hash functions.
1343 2013-02-09 Eli Zaretskii <eliz@gnu.org>
1345 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
1346 XXXXXX part of the temporary file pattern is not downcased even
1347 when w32-downcase-file-names is non-nil. (Bug#13661)
1349 * xdisp.c (decode_mode_spec): Remove handling of %t.

1398 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
1401 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.

1407 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
1408 (x_set_window_size): Do not take title bar and tool bar into account
1409 if isFullscreen returns YES.
1410 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
1411 (check_native_fs): New function.
1412 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
1413 (ns_term_init): Remove NEW_STYLE_FS.
1414 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
1415 and tool bar if isFullscreen returns NO.
1416 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
1417 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
1418 with HAVE_NATIVE_FS.
1419 (window:willUseFullScreenPresentationOptions:): New method.
1420 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
1421 Hide toolbar if not enabled (Bug#13444).
1422 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
1423 Restore tool bar if enabled, hide it otherwise (Bug#13444).
1424 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
1425 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
1426 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
1427 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
1428 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
1429 (syms_of_nsterm): Add ns-use-native-fullscreen.
1431 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
1433 * fileio.c (Qchoose_write_coding_system): Now static.
1435 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1437 * xdisp.c (window_buffer_changed): region_showing can be negative,
1438 which still means region is being displayed.
1439 (redisplay_internal): Resurrect code that forced redisplay of the
1440 whole window when showing region and the mark has changed.
1441 Record the new mark position to allow redisplay optimizations.
1442 (display_line): If it->region_beg_charpos is non-zero, set the
1443 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1445 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1446 not bitfield of 1 bit.
1448 2013-02-03 Daniel Colascione <dancol@dancol.org>
1450 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1451 daemon mode works on cygw32 when Emacs is installed and not just
1454 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1456 Avoid file time stamp bug on MS-Windows (Bug#13149).
1457 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1458 as FAT32 doesn't update time stamps when truncating them.
1459 Also, check that a file time stamp is not a multiple of 100 ns;
1460 this should catch all instances of the problem on MS-Windows,
1461 as its native file system resolution is 100 ns or worse, and
1462 checking for a non-multiple of 100 ns should impose only a small
1463 overhead on systems with ns resolution.
1465 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1467 Avoid encoding file names on MS-Windows when they need to be run
1468 through dostounix_filename.
1469 * w32.c (normalize_filename): Accept an additional argument
1470 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1471 downcase it even if w32-downcase-file-names is non-nil.
1472 (dostounix_filename): Accept an additional argument MULTIBYTE and
1473 pass it to normalize_filename.
1474 (emacs_root_dir): Adjust.
1476 * msdos.h (dostounix_filename): Adjust prototype.
1478 * w32.h (dostounix_filename): Adjust prototype.
1480 * msdos.c (dostounix_filename): Accept an additional argument and
1482 (init_environment): Adjust callers of dostounix_filename.
1484 * fileio.c (Ffile_name_directory, file_name_as_directory)
1485 (directory_file_name, Fexpand_file_name)
1486 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1488 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1490 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1491 variables, as egetenv is case-insensitive for DOS_NT.
1493 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1494 with an encoded file name.
1496 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1497 Adjust calls to dostounix_filename.
1499 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1501 * unexw32.c (unexec): Adjust call to dostounix_filename.
1503 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1505 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1508 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1511 * callproc.c (Fcall_process): Make sure program name in PATH and
1512 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1513 is passed to exec/spawnve, which fails unless the file-name
1516 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1517 even if w32-quote-process-args is nil.
1519 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1521 Fix timestamp bug when write-region appends nothing (Bug#13149).
1522 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1523 the file's time stamp doesn't change if Emacs happens to write nothing
1524 to the file, and on a buggy file system this could cause Emacs to
1525 incorrectly infer that the file system doesn't have the bug.
1526 Avoid this problem by inhibiting the inference in this case.
1528 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1530 * window.h (struct window): Convert base_line_number, base_line_pos
1531 and column_number_displayed members from Lisp_Object to ptrdiff_t.
1532 Convert region_showing member from Lisp_Object to bitfield.
1533 Remove sequence_number member. Adjust comments.
1534 * window.c (sequence_number): Remove.
1535 (make_window): Initialize column_number_displayed.
1536 * print.c (print_object): Follow the printed representation of
1537 frames and print window pointer to distinguish between windows.
1538 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
1539 * xdisp.c (wset_base_line_number, wset_base_line_pos)
1540 (wset_column_number_displayed, wset_region_showing): Remove.
1541 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1542 (try_scrolling, try_cursor_movement, redisplay_window)
1543 (try_window_reusing_current_matrix, try_window_id, display_line)
1544 (display_mode_lines, decode_mode_spec): Adjust users.
1545 * .gdbinit (pwinx): Do not print sequence_number.
1547 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1549 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1550 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1551 * dired.c: Include <fcntl.h>.
1552 (open_directory): New function, which uses open and fdopendir
1553 rather than opendir. DOS_NT platforms still use opendir, though.
1554 (directory_files_internal, file_name_completion): Use it.
1555 (file_attributes): New function, with most of the old Ffile_attributes.
1556 (directory_files_internal, Ffile_attributes): Use it.
1557 (file_attributes, file_name_completion_stat): First arg is now fd,
1558 not dir name. All uses changed. Use fstatat rather than lstat +
1560 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1561 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1562 (emacs_readlinkat): New function, with much of the old
1563 Ffile_symlink_p, but with an fd argument for speed.
1564 It uses readlinkat rather than careadlinkatcwd, so that it
1565 need not assume the working directory.
1566 (Ffile_symlink_p): Use it.
1567 * filelock.c (current_lock_owner): Use emacs_readlinkat
1568 rather than emacs_readlink.
1569 * lisp.h (emacs_readlinkat): New decl.
1570 (READLINK_BUFSIZE, emacs_readlink): Remove.
1571 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1572 (emacs_norealloc_allocator, emacs_readlink): Remove.
1573 This stuff is moved to fileio.c.
1574 * w32.c (fstatat, readlinkat): New functions.
1575 (careadlinkat): Don't check that fd == AT_FDCWD.
1576 (careadlinkatcwd): Remove; no longer needed.
1578 2013-01-31 Glenn Morris <rgm@gnu.org>
1580 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
1581 (Fwrite_region): Update for new choose_write_coding_system args.
1582 Move the last piece of choose_write_coding_system here. (Bug#13522)
1583 (syms_of_fileio): Add choose-write-coding-system.
1585 2013-01-30 Eli Zaretskii <eliz@gnu.org>
1587 * w32.c (sys_open): Zero out the flags for the new file descriptor.
1588 (sys_close): Zero out the flags for the file descriptor before
1589 closing it. (Bug#13546)
1591 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1592 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1593 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1596 * w32.c (w32_get_long_filename, init_environment, readlink):
1597 Support file names encoded in DBCS codepages.
1598 (readlink): Use the current file-name-coding-system, not the ANSI
1599 codepage, to decode and handle targets of symlinks.
1601 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1603 * w32.c (opendir): Now accepts a 'const char *'.
1605 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
1607 Remove obsolete redisplay code. See the discussion at
1608 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
1609 * dispnew.c (preemption_period, preemption_next_check): Remove.
1610 (Vredisplay_preemption_period): Likewise.
1611 (update_frame, update_single_window, update_window, update_frame_1):
1612 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
1613 used, following the 2012-06-22 change.
1615 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1617 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1619 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
1621 * font.c (num_fonts): Remove the leftover from old
1622 debugging code. Adjust comment style here and there.
1623 * insdel.c (insert_1): Remove.
1624 * lisp.h (insert_1): Remove prototype.
1625 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
1627 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1629 * w32.c (max_filename_mbslen): New function.
1630 (normalize_filename, readdir): Use it to detect locales where ANSI
1631 encoding of file names uses a double-byte character set (DBCS).
1632 If a DBCS encoding is used, advance by characters using
1633 CharNextExA, instead of incrementing a 'char *' pointer.
1634 Use _mbslwr instead of _strlwr. (Bug#13515)
1636 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1637 request of memory reservation to 1.7GB. (Bug#13065)
1639 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
1641 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
1642 at check_extra_latin label. (Bug#13505)
1644 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1646 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
1647 Avoid redundant calls to strlen.
1649 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1651 Drop async_visible and async_iconified fields of struct frame.
1652 This is possible because async input is gone; for details, see
1653 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1654 * frame.h (struct frame): Remove async_visible and async_iconified
1655 members, convert garbaged to unsigned bitfield. Adjust comments.
1656 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
1657 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
1658 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
1659 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
1660 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
1662 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
1663 properly. Likewise for obscured.
1665 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
1668 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
1670 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1672 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
1673 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1675 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1677 * xdisp.c (message2, message2_nolog): Remove functions.
1678 (message3, message3_nolog): Extract nbytes and multibyteness directly
1679 from the string. Change all callers.
1680 (message3_nolog): Don't set message_enable_multibyte since set_message
1681 will reset it anyway.
1682 (message1, message1_nolog): Use message3.
1683 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1684 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1685 (set_message): Drop all but the second arg, which has to be a string.
1686 (set_message_1): Simplify now that we know that a1 is NULL and the
1687 second arg is a string.
1688 * frame.h (struct frame): Remove `message_buf' field.
1689 Use glyphs_initialized_p instead.
1690 (FRAME_MESSAGE_BUF): Remove macro.
1691 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
1692 * lisp.h (message2, message2_nolog): Remove declarations.
1693 (message3, message3_nolog): Update declarations.
1694 * keyboard.c (read_char_minibuf_menu_text)
1695 (read_char_minibuf_menu_width): Remove vars.
1696 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
1697 to correctly handle multibyte strings.
1698 * frame.c (delete_frame): Don't free message_buf any more.
1699 * editfns.c (message_text, message_length): Remove vars.
1700 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1701 * fileio.c (auto_save_error): Use message3 instead of message2.
1702 * dispnew.c (adjust_frame_message_buffer): Remove function.
1704 2013-01-23 Eli Zaretskii <eliz@gnu.org>
1706 * w32term.c (w32fullscreen_hook): Account correctly for the screen
1707 real estate used for the tool bar and the menu bar.
1709 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
1711 * insdel.c (prepare_to_modify_buffer): Force redisplay if
1712 hidden buffer is prepared to modification (Bug#13164).
1714 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1716 * window.h (struct window): Change window_end_valid member from
1717 Lisp_Object to a bitfield. Adjust comments.
1718 (wset_window_end_valid): Remove.
1719 * window.c (adjust_window_count): Clear window_end_valid.
1720 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
1721 (Fwindow_line_height, set_window_buffer, Frecenter)
1722 (Fsplit_window_internal, Fdelete_other_windows_internal)
1723 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
1724 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
1725 * xdisp.c (check_window_end, reconsider_clip_changes)
1726 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1727 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1728 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1730 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1732 * xdisp.c (mark_window_display_accurate): Simplify the loop
1733 assuming that the only one of vchild, hchild or buffer window
1734 slots is non-nil. Call mark_window_display_accurate_1 for
1735 the leaf windows only.
1736 (mark_window_display_accurate_1): Always assume leaf window.
1739 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1741 * emacs.c (Qkill_emacs_hook): Now static.
1743 * fileio.c (Finsert_file_contents): Simplify.
1744 Remove unnecessary assignments and tests.
1746 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1748 * w32.c (acl_set_file): Don't test for errors unless
1749 set_file_security returns FALSE. Avoids spurious errors when
1752 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1754 * fileio.c (Finsert_file_contents): Revert code introduced at
1755 2013-01-18 in favor of the simpler and generally better fix.
1756 Save stack space by removing 'buffer' and reusing 'read_buf'
1759 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1761 * lisp.h (eabs): Define unconditionally (Bug#13419).
1762 The old "#if !defined (eabs)" was an unnecessary revenant of back
1763 when this macro was called "abs". Document 'eabs' better.
1765 2013-01-19 Glenn Morris <rgm@gnu.org>
1767 * fns.c (Frandom): Doc fix.
1769 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1771 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1772 segfault when there are lots of overlays.
1774 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1775 when there are lots of overlays.
1776 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1777 for the details and a way to reproduce.
1779 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1781 * fileio.c: Use O_APPEND to append.
1782 This corresponds better to the natural interpretation of "append",
1783 and avoids the need to open the output file twice, or to invoke
1784 lseek when APPEND is neither nil nor a number.
1785 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1786 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1787 file possibly twice, and lseeking to its end; this avoids the
1788 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1789 at the same time: the combination is never needed and apparently
1790 it doesn't work with DOS_NT.
1792 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1793 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1795 Allow floating-point file offsets.
1796 Problem reported by Vitalie Spinu in
1797 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1798 * fileio.c (emacs_lseek): Remove.
1799 (file_offset): New function.
1800 (Finsert_file_contents, Fwrite_region): Use it.
1802 2013-01-19 Chong Yidong <cyd@gnu.org>
1804 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1805 aborting on Fsignal (Bug#13289).
1807 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1809 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1810 set_file_security as failure due to insufficient privileges.
1811 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1812 (fstat): Return owner and group like 'stat' and 'lstat' do.
1814 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1816 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1817 The bug was observed on Ubuntu operating inside a virtual machine,
1818 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1819 The workaround introduces a race condition on non-buggy hosts,
1820 but it's an unlikely race and anyway there's a nearly identical
1821 nearby race that can't be fixed.
1822 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1824 (Fwrite_region): Test for file system time stamp bug.
1825 (init_fileio): New function.
1826 * lisp.h (init_fileio): Declare it.
1827 * emacs.c (main): Call it.
1829 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1830 and make it more consistent with other stat-failure diagnostics.
1832 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
1834 Fix crash when inserting data from non-regular files.
1835 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
1836 for the error description produced by valgrind.
1837 * fileio.c (read_non_regular): Rename to read_contents.
1838 Free Lisp_Save_Value object used to pass parameters.
1839 (read_non_regular_quit): Rename to read_contents_quit.
1840 (Finsert_file_contents): Redesign internal file reading loop to adjust
1841 gap and end positions after each read and so help make_gap to work
1842 properly. Do not signal an I/O error too early and so do not leave
1843 not yet decoded characters in a buffer, which was the reason of
1844 redisplay crash. Use list2 to build return value. Adjust comments.
1846 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1848 Close a race when statting and reading files (Bug#13149).
1849 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1850 This avoids a race if the file is renamed between stat and open.

2264 * frame.c (Fframep): Adjust user here ...
2265 * terminal.c (Fterminal_live_p): ... and here.
2266 * coding.c (Qmac): Now here because it's only used to denote

2268 (syms_of_coding): DEFSYM it.
2269 * frame.h (Qmac): Remove duplicated declaration.
2271 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>

2280 for the original report.
2282 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>

2314 thread shutdown when delete_child triggers it.
2315 (reap_subprocess): More accurate commentary for why we call
2316 delete_child only when cp->fd is negative.
2318 * w32.c (sys_close): Do not call delete_child on a subprocess
2319 whose handle is not yet closed. Instead, set its file descriptor
2320 to a negative value, so that reap_subprocess will call
2321 delete_child on that subprocess when its SIGCHLD arrives.
2322 This avoids closing handles used for communications between sys_select
2323 and reader_thread, which doesn't give sys_select a chance to
2324 notice that the process exited and invoke the SIGCHLD handler for
2327 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
2329 * nsfns.m (Fns_do_applescript): Run event loop until script has

2340 * w32term.c (w32fullscreen_hook): New function.
2341 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
2343 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2345 * fileio.c (Finsert_file_contents): Doc fix.
2347 * w32proc.c (new_child, delete_child, find_child_pid): For a
2348 subprocess, consider its slot being in use as long as its process
2349 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2350 slot when a new process is started immediately after killing
2351 another one, without waiting enough time for the first process to
2352 be reaped and resources allocated for it be orderly freed.
2354 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2356 2012-12-21 Chong Yidong <cyd@gnu.org>

2362 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2364 * w32.c (get_name_and_id): Always pass NULL as the first argument
2365 of lookup_account_sid. Avoids crashes with UNC file names that
2366 refer to DFS domains, not to specific machine names. (Bug#12621)
2367 Remove now unused argument FNAME; all callers changed.
2368 (get_file_owner_and_group): Remove now unused argument FNAME; all
2371 2012-12-21 Chong Yidong <cyd@gnu.org>
2373 * editfns.c (Finsert_char): Since read-char-by-name now signals an
2374 error for invalid chars, don't check for a nil return value.
2376 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2378 Avoid calls to CHAR_TO_BYTE if byte position is known.
2379 * editfns.c (make_buffer_string_both): Use move_gap_both.

2384 (charpos_to_bytepos): Remove.
2385 * fileio.c (Finsert_file_contents): Use move_gap_both.
2386 * search.c (Freplace_match): Likewise.

2400 (redisplay_internal): Don't bother selecting the frame to get the
2401 proper value of frame-local variables (bug#13225).
2403 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2405 * textprop.c (set_text_properties_1): Do not allow NULL interval.
2406 Rename 4th argument since it may be buffer or string. Adjust comment.
2407 * intervals.c (graft_intervals_info_buffer): Find an interval here.
2409 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
2411 * coding.c (Fdetect_coding_region): Do not check start and end with
2412 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
2413 (code_convert_region): Likewise.
2415 2012-12-18 Eli Zaretskii <eliz@gnu.org>
2417 * w32.c (acl_get_file, acl_set_file): Run the file name through
2418 map_w32_filename, and resolve any symlinks in the file name, like

2430 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
2431 propagate redisplay's scrolling (if any) to the right window.
2432 (redisplay_internal): Use ensure_selected_frame.
2433 (display_mode_lines): Complete last fix.
2434 * window.c (select_window_1): New func, extracted from select_window.
2435 (select_window): Use it.
2436 * window.h (select_window_1): Declare.

2462 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
2464 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2465 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2466 for some of that bug's symptoms can now cause Emacs to abort.
2467 Remove the workaround.
2468 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2469 The bug that caused SIGCHLD to get lost has been fixed, and the
2470 workaround for it can now cause Emacs to abort.
2472 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2474 * sysdep.c (emacs_abort): Bump backtrace size to 40.
2475 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
2476 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

2480 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
2481 (Fcopy_file): Change last arg to `preserve_extended_attributes'
2482 and copy ACL entries of file in addition to SELinux context if set.
2483 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
2485 * Makefile.in (LIBACL_LIBS): New macro.

2500 * w32proc.c (new_child): Initialize input_file and
2501 pending_deletion members of the child.
2502 (delete_child): Delete the child's temporary input file, if any,
2503 that is pending deletion.

2505 (record_infile, record_pending_deletion): New functions.
2506 (reap_subprocess): Fix a typo in DebPrint string.
2507 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
2509 * fileio.c (internal_delete_file): Return an int again: non-zero
2510 if delete-file succeeds, zero otherwise.
2512 * lisp.h (internal_delete_file): Adjust prototype.
2514 * callproc.c (Fcall_process): Don't overwrite infile with result
2516 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
2517 asynchronous subprocess, record the name of the input file name,
2519 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
2520 delete the file, record it as pending deletion when the subprocess
2523 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2525 * editfns.c [HAVE_PWD_H]: Include grp.h.

2531 Fix permissions bugs with setgid directories etc. (Bug#13125)
2532 * dired.c (Ffile_attributes): Return t as the 9th attribute,

2536 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
2538 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

2543 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2545 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
2546 try to get accurate owner and group information from NT file
2547 security APIs. This is to make most callers of 'stat' and
2548 'lstat', which don't need that information, much faster.
2550 * dired.c (Ffile_attributes) [WINDOWSNT]:
2551 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2552 owner and group information from 'lstat'.
2554 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2556 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2557 as that confuses set-auto-coding, so insist on the head-read
2558 returning the full 1024 bytes. Let lseek compute the tail offset;
2559 less work for us. Do not ignore I/O errors when reading the tail.

2562 (init_iterator): Hoist assignment out of if-expression.
2563 (markpos_of_region): Callers now test for sign, not for -1.

2577 character in pattern when the buffer being searched is unibyte.
2580 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2582 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
2583 files, fixing a regression from 24.2.
2584 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
2586 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2588 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2589 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2590 Remove unnecessary S_ISLNK test, as (contra the comments) this
2591 function can't copy symlinks. Improve quality of error message
2592 when attempting to copy files that are neither regular files nor

2601 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
2603 2012-12-12 Daniel Colascione <dancol@dancol.org>
2605 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
2606 the dumped Emacs is not a sparse file, greatly improving Cygwin
2607 "make bootstrap" performance.
2609 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
2611 * inotify.c (inotify_callback): Generate an Emacs event for every
2612 incoming inotify event.
2614 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2616 * xdisp.c (handle_face_prop): Fix logic of computing
2617 it->start_of_box_run_p.
2618 (append_space_for_newline): If the glyph row is R2L, reset the
2619 iterator's end_of_box_run_p flag before prepending the space glyph.
2620 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
2621 iterator's start_of_box_run_p flag before prepending the stretch.
2622 (append_glyph, produce_image_glyph, append_composite_glyph)
2623 (append_stretch_glyph, append_glyphless_glyph): Reverse the
2624 left_box_line_p and right_box_line_p flags of the glyph for R2L
2625 glyph rows. (Bug#13011)
2627 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

2675 (hinst): Remove unneeded extern declaration.
2676 (_start): Remove initialization of above variables; remove

2798 2012-12-10 Christopher Schmidt <christopher@ch.ristopher.com>
2800 * lread.c (Vload_source_file_function): Doc fix (Bug#11647).
2802 2012-12-10 Eli Zaretskii <eliz@gnu.org>
2804 * indent.c (Fvertical_motion): If a display string will be
2805 displayed on the left or the right margin, don't consider it as a
2806 factor in cursor positioning. (Bug#13108)
2808 2012-12-10 Martin Rudalics <rudalics@gmx.at>
2810 * editfns.c (Fcompare_buffer_substrings): Reword doc-string.
2812 2012-12-10 Paul Eggert <eggert@cs.ucla.edu>
2814 * fileio.c (Fsubstitute_in_file_name): Use ptrdiff_t, not int,
2817 2012-12-08 Eli Zaretskii <eliz@gnu.org>
2819 * w32.c (unsetenv): Return 0 if the input string is too long.
2821 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
2823 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
2824 * alloc.c (xputenv): New function.
2825 * dbusbind.c (Fdbus_init_bus):
2827 * xterm.c (x_term_init):
2828 Use xputenv instead of setenv or putenv, to detect memory exhaustion.
2829 * editfns.c (initial_tz): Move static var decl up.
2830 (tzvalbuf_in_environ): New static var.
2831 (init_editfns): Initialize these two static vars.
2832 (Fencode_time): Don't assume arbitrary limit on EMACS_INT width.
2833 Save old TZ value on stack, if it's small.
2834 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
2835 instead, use xputenv+unsetenv to set and restore TZ.
2836 (environbuf): Remove static var. All uses removed.
2837 (Fset_time_zone_rule): Do not save TZ and environ;
2838 no longer needed here.
2839 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
2840 Move to inside set_time_zone_rule; they don't need file scope any more.
2841 (set_time_zone_rule): Maintain the TZ=value string separately.
2842 (syms_of_editfns): Don't initialize initial_tz;
2843 init_editfns now does it.
2844 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
2845 * lisp.h (xputenv): New decl.
2847 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
2849 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
2851 2012-12-08 Eli Zaretskii <eliz@gnu.org>
2853 * w32.c (unsetenv, sys_putenv): New functions.
2855 2012-12-08 Chong Yidong <cyd@gnu.org>
2857 * editfns.c (Finsert_char): Make the error message more
2858 informative (Bug#12992).
2860 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
2862 Simplify get_lim_data.
2863 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
2864 Remove USG and vlimit methods; no longer used these days.
2865 Add #error catchall just in case.
2867 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
2868 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
2869 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
2870 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
2871 (deleted_pid_list, Fdelete_process, create_process)
2872 (record_child_status_change, handle_child_signal, deliver_child_signal)
2873 (init_process_emacs, syms_of_process):
2874 Assume SIGCHLD is defined.
2875 (parse_signal): Remove. All uses removed.
2876 (abbr_to_signal): New static function.
2877 (Fsignal_process): Use it to convert signal names to ints.
2878 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
2879 kill (getpgrp (), ...).
2880 (emacs_sigaction_init): Assume SIGCHLD is defined.
2881 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
2882 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
2883 * syssignal.h (EMACS_KILLPG): Remove.
2884 All uses replaced by 'kill' with a negative pid.
2885 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
2886 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
2888 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
2890 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
2891 This will cause a production Emacs to dump core instead of
2894 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2896 * frame.c (make_frame): Do not set window's buffer to t.
2897 * window.c (Fsplit_window_internal): Likewise. Previously it was
2898 used to indicate that the window is being set up. Now we use
2899 set_window_buffer for all new windows, so the condition in ...
2900 (Fset_window_buffer): ... is always true and can be removed.
2902 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2904 Convenient macro to check whether the buffer is hidden.
2905 * buffer.h (BUFFER_HIDDEN_P): New macro.
2906 * frame.c (make_frame): Use it. Adjust comment.
2907 * buffer.c (candidate_buffer): New function.
2908 (Fother_buffer, other_buffer_safely): Use it.
2910 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2912 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
2913 if the child process is still running. Instead, exit the wait
2914 loop and return zero. (Bug#13086)
2916 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2918 * frame.h (x_char_width, x_char_height): Remove prototypes.
2919 * w32term.h (x_char_width, x_char_height): Likewise.
2920 * xfns.c (x_char_width, x_char_height): Remove.
2921 * w32fns.c (x_char_width, x_char_height): Likewise.
2922 * nsfns.c (x_char_width, x_char_height): Likewise.
2923 * frame.c (Fframe_char_width): Use FRAME_COLUMN_WIDTH for
2925 (Fframe_char_height): Likewise with FRAME_LINE_HEIGHT.
2926 * keyboard.c (command_loop_1): Remove prototype.
2927 (command_loop_2, top_level_1): Add static to match prototype.
2929 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
2931 Fix a recently-introduced delete-process race condition.
2932 * callproc.c, process.h (record_kill_process):
2933 New function, containing part of the old call_process_kill.
2934 (call_process_kill): Use it.
2935 This does not change call_process_kill's behavior.
2936 * process.c (Fdelete_process): Use record_kill_process to fix a
2937 race condition that could cause Emacs to lose track of a child.
2939 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2941 Avoid code duplication between prev_frame and next_frame.
2942 * frame.c (candidate_frame): New function. Add comment.
2943 (prev_frame, next_frame): Use it. Adjust comment.
2945 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2947 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2948 fails, signal an error instead of continuing with an empty
2950 Encode expanded temp file pattern before passing it to mkstemp or
2953 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2954 Encode the file name before passing it to dostounix_filename, in
2955 case it will downcase it (under w32-downcase-file-names).
2958 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2960 Minor call-process cleanups.
2961 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2962 at the same time as other platforms, to simplify analysis.
2963 No need for fd0_volatile since we have synch_process_fd.
2964 Avoid needless emacs_close; arg is always negative.
2966 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2968 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2971 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2973 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2974 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2975 and mouse_face_hidden members to a bitfields.
2976 * frame.h (struct frame): Remove set-but-not-used space_width member.
2977 (FRAME_SPACE_WIDTH): Remove.
2978 * nsterm.m, w32term.c, xterm.c: Adjust users.
2979 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2980 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2981 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2982 members to a bitfields.
2984 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2986 Don't let call-process be a zombie factory (Bug#12980).
2987 Fixing this bug required some cleanup of the signal-handling code.
2988 As a side effect, this change also fixes a longstanding rare race
2989 condition whereby Emacs could mistakenly kill unrelated processes,
2990 and it fixes a bug where a second C-g does not kill a recalcitrant
2991 synchronous process in GNU/Linux and similar platforms.
2992 The patch should also fix the last vestiges of Bug#9488,
2993 a bug which has mostly been fixed on the trunk by other changes.
2994 * callproc.c, process.h (synch_process_alive, synch_process_death)
2995 (synch_process_termsig, sync_process_retcode):
2996 Remove. All uses removed, to simplify analysis and so that
2997 less consing is done inside critical sections.
2998 * callproc.c (call_process_exited): Remove. All uses replaced
2999 with !synch_process_pid.
3000 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
3001 These take the role of what used to be in unwind-protect arg.
3003 (block_child_signal, unblock_child_signal):
3004 New functions, to avoid races that could kill innocent-victim processes.
3005 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
3006 (call_process_kill): Record killed processes as deleted, so that
3007 zombies do not clutter up the system. Do this inside a critical
3008 section, to avoid a race that would allow the clutter.
3009 (call_process_cleanup): Fix code so that the second C-g works again
3010 on common platforms such as GNU/Linux.
3011 (Fcall_process): Create the child process in a critical section,
3012 to fix a race condition. If creating an asynchronous process,
3013 record it as deleted so that zombies do not clutter up the system.
3014 Do unwind-protect for WINDOWSNT too, as that's simpler in the
3015 light of these changes. Omit unnecessary call to emacs_close
3016 before failure, as the unwind-protect code does that.
3017 * callproc.c (call_process_cleanup):
3018 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
3019 * process.c (record_deleted_pid): New function, containing
3020 code refactored out of Fdelete_process.
3021 (Fdelete_process): Use it.
3022 (process_status_retrieved): Remove. All callers changed to use
3023 child_status_change.
3024 (record_child_status_change): Remove, folding its contents into ...
3025 (handle_child_signal): ... this signal handler. Now, this
3026 function is purely a handler for SIGCHLD, and is not called after
3027 a synchronous waitpid returns; the synchronous code is moved to
3028 wait_for_termination. There is no need to worry about reaping
3029 more than one child now.
3030 * sysdep.c (get_child_status, child_status_changed): New functions.
3031 (wait_for_termination): Now takes int * status and bool
3032 interruptible arguments, too. Do not record child status change;
3033 that's now the caller's responsibility. All callers changed.
3034 Reimplement in terms of get_child_status.
3035 (wait_for_termination_1, interruptible_wait_for_termination):
3036 Remove. All callers changed to use wait_for_termination.
3037 * syswait.h: Include <stdbool.h>, for bool.
3038 (record_child_status_change, interruptible_wait_for_termination):
3040 (record_deleted_pid, child_status_changed): New decls.
3041 (wait_for_termination): Adjust to API changes noted above.
3043 * bytecode.c, lisp.h (Qbytecode): Remove.
3044 No longer needed after 2012-11-20 interactive-p changes.
3046 2012-12-03 Eli Zaretskii <eliz@gnu.org>
3048 * xdisp.c (redisplay_window): If the cursor is visible, but inside
3049 the scroll margin, move point outside the margin. (Bug#13055)
3051 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
3053 * gtkutil.c (my_log_handler): New function.
3054 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
3056 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3058 * lisp.h (modify_region): Rename to...
3059 (modify_region_1): ...new prototype.
3060 * textprop.c (modify_region): Now static. Adjust users.
3061 * insdel.c (modify_region): Rename to...
3062 (modify_region_1): ...new function to work with current buffer.
3063 Adjust comment and users. Use true and false for booleans.
3065 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3067 * alloc.c (free_save_value): New function.
3068 (safe_alloca_unwind): Use it.
3069 * lisp.h (free_save_value): New prototype.
3070 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
3072 (save_excursion_restore): Adjust to match saved data structure.
3073 Use free_save_value to offload some work from GC. Drop obsolete
3076 2012-12-03 Chong Yidong <cyd@gnu.org>
3078 * fileio.c (Vauto_save_list_file_name): Doc fix.
3080 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
3082 * w32fns.c: Remove prototype of atof.
3083 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
3085 (file_dialog_callback): Make it UINT_PTR.
3087 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
3090 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3091 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
3094 2012-12-03 Glenn Morris <rgm@gnu.org>
3096 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
3098 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
3100 Fix xpalloc confusion after memory is exhausted.
3101 * alloc.c (xpalloc): Comment fix.
3102 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
3103 and signals an error, do not clear charset_table_size, as
3104 charset_table is still valid.
3105 * doprnt.c (evxprintf): Clear *BUF after freeing it.
3107 Use execve to avoid need to munge environ (Bug#13054).
3108 * callproc.c (Fcall_process):
3109 * process.c (create_process):
3110 Don't save and restore environ; no longer needed.
3111 * callproc.c (child_setup):
3112 Use execve, not execvp, to preserve environ.
3114 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
3116 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
3118 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3120 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
3121 display for sliced images (Bug#10500).
3123 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
3125 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
3127 * doc.c (Fdocumentation): Re-add handling of function-documentation,
3128 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
3130 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
3132 * xdisp.c (window_outdated): Remove eassert since it hits
3133 some suspicious corner cases (see Bug#13007 and Bug#13012).
3134 (mode_line_update_needed): New function.
3135 (redisplay_internal, redisplay_window): Use it.
3136 (ensure_selected_frame): New function.
3137 (redisplay_internal, unwind_redisplay): Use it.
3138 (redisplay_internal): Move comment about buffer_shared...
3139 (buffer_shared_and_changed): ...near to its real use.
3141 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
3143 * callproc.c (Fcall_process): Don't misreport vfork failure.
3145 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
3147 * callproc.c (Fcall_process): Fix vfork portability problems.
3148 Do not assume that fd[0], count, filefd, and save_environ survive
3149 vfork. Fix bug whereby wrong errno value could be reported for
3150 pipe failure. Some minor cleanups, too, as follows. Move buf and
3151 bufsize to the context where they're needed. Change new_argv to
3152 be of type char **, as this is more convenient and avoids casts.
3153 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
3154 Now local constants, not macros.
3156 2012-11-18 Kenichi Handa <handa@gnu.org>
3158 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
3159 for the variable "f".
3161 2012-11-13 Kenichi Handa <handa@gnu.org>
3163 * font.c (font_unparse_xlfd): Exclude special characters from the
3164 generating XLFD name.
3166 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
3168 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.
3169 * dired.c (stat_uname, stat_gname):
3170 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
3172 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

3174 Assume EAGAIN and EINTR are defined.
3176 * fileio.c (Fcopy_file): Assume EISDIR is defined.
3177 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
3178 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
3179 * lread.c (readbyte_from_file): Assume EINTR is defined.
3180 * process.c (wait_reading_process_output, send_process) [subprocesses]:
3181 Assume EIO and EAGAIN are defined.
3182 * unexcoff.c (write_segment): Assume EFAULT is defined.
3184 2012-11-27 Eli Zaretskii <eliz@gnu.org>
3186 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
3189 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
3190 highlighting on the frame was cleared. Prevents assertion
3191 violations when repeatedly clicking on the "Top" link of the
3192 "bread-crumbs" in Info buffers.
3194 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
3196 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
3198 2012-11-24 Ken Brown <kbrown@cornell.edu>
3200 * keyboard.c (HAVE_MOUSE):
3201 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
3202 were always defined.
3204 2012-11-24 Eli Zaretskii <eliz@gnu.org>
3206 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
3207 between bpos_covered and bpos_max. This fixes cursor display when
3208 several display strings follow each other.
3210 * .gdbinit (pgx): If the glyph's object is a string, display the
3211 pointer to string data, rather than the value of the string object
3212 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
3214 * indent.c (Fvertical_motion): If the starting position is covered
3215 by a display string, return to one position before that, to avoid
3216 overshooting it inside move_it_to. (Bug#12930)
3218 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
3220 * frame.h (struct frame): Remove display_preempted member
3221 since all users are dead long ago.

3223 * w32menu.c (pending_menu_activation): Remove since not
3225 (set_frame_menubar): Adjust user.
3226 * w32term.h (struct x_output): Drop outdated #if 0 code.
3227 (struct w32_output): Use bitfields for explicit_parent,
3228 asked_for_visible and menubar_active members.
3229 Drop unused pending_menu_activation member.
3230 * xterm.h (struct x_output): Drop outdated #if 0 code.
3231 Use bitfields for explicit_parent, asked_for_visible,
3232 has_been_visible and net_wm_state_hidden_seen members.
3234 2012-11-23 Eli Zaretskii <eliz@gnu.org>
3236 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
3237 of a literal "/". (Bug#12955)
3238 (gl-stamp): Invoke fc.exe directly, not through cmd.
3240 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
3242 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
3243 * dired.c: Assume HAVE_DIRENT_H.
3244 (NAMLEN): Remove, replacing with ...
3245 (dirent_namelen): New function. All uses changed. Use the GNU macro
3246 _D_EXACT_NAMELEN if available, as it's faster than strlen.
3247 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
3248 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
3249 * makefile.w32-in (DIR_H): Remove. All uses replaced with
3251 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
3252 * ndir.h: Rename to ../nt/inc/dirent.h.
3253 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
3254 Do not include <dirent.h>; no longer needed.
3255 * w32.c: Include <dirent.h> rather than "ndir.h".
3257 2012-11-23 Chong Yidong <cyd@gnu.org>
3259 * xftfont.c (xftfont_open): Remove duplicate assignment.
3261 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3263 * alloc.c (Fgarbage_collect): Unblock input after clearing
3264 gc_in_progress to avoid note_mouse_highlight glitch with GC.
3265 * frame.h (FRAME_MOUSE_UPDATE): New macro.
3266 * msdos.c (IT_frame_up_to_date): Use it here...
3267 * w32term.c (w32_frame_up_to_date): ...here...
3268 * xterm.c (XTframe_up_to_date): ...and here...
3269 * nsterm.m (ns_frame_up_to_date): ...but not here.
3270 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
3272 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
3273 Do not check whether GC is in progress.
3275 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3277 * xdisp.c (window_buffer_changed): New function.
3278 (update_menu_bar, update_tool_bar): Use it to
3279 simplify large 'if' statements.
3280 (redisplay_internal): Generalize commonly used
3281 'tail' and 'frame' local variables.
3283 2012-11-22 Eli Zaretskii <eliz@gnu.org>
3285 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
3286 with Windows system header.
3288 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
3290 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
3291 * alloc.c: Assume unistd.h exists.
3292 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
3293 * sysdep.c (get_current_dir_name): Assume getcwd exists.
3294 (getwd) [USG]: Remove; no longer needed.
3295 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
3296 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
3297 * w32.h (getcwd): Remove decl.
3299 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
3301 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
3302 Make it set selected_window as well.
3303 (update_tool_bar): Use it.
3305 2012-11-21 Ken Brown <kbrown@cornell.edu>
3307 * emacs.c (main): Set the G_SLICE environment variable for all
3308 Cygwin builds, not just GTK builds. See
3309 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
3311 2012-11-21 Eli Zaretskii <eliz@gnu.org>
3313 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3314 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
3315 Define for the MSVC compiler.
3317 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
3319 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
3320 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
3321 dostounix_filename. Prevents crashes down the road, because
3322 dostounix_filename assumes it gets a unibyte string.
3323 Reported by Michel de Ruiter <michel@sentient.nl>, see
3324 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
3326 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

3330 * lread.c (init_obarray): Set `function' fields to Qnil.
3331 * eval.c (Fcommandp): Ignore Qunbound.
3332 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
3333 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
3334 Test NILP rather than Qunbound.
3335 (Ffmakunbound): Set to Qnil.
3336 (Fsymbol_function): Never signal an error.
3337 (Finteractive_form): Ignore Qunbound.
3339 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
3341 * eval.c (interactive_p): Remove no-longer-used decl.
3343 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
3345 * xdisp.c (buffer_shared): Adjust comment.
3346 (buffer_shared_and_changed): New function.
3347 (prepare_menu_bars, redisplay_internal): Use it to
3348 decide whether all windows or frames should be updated.
3349 (window_outdated): New function.
3350 (text_outside_line_unchanged_p, redisplay_window): Use it.
3351 (redisplay_internal): Likewise. Fix indentation.
3353 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
3355 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
3356 (syms_of_eval): Remove corresponding defsubr.
3357 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
3359 2012-11-19 Daniel Colascione <dancol@dancol.org>
3361 * w32fns.c (Fx_file_dialog):
3362 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
3363 cygwin_convert_file_name*.
3365 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
3366 Rename cygwin_convert_path* to cygwin_convert_file_name*.
3368 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
3370 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3372 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3374 * w32select.c: Include w32common.h before w32term.h, so that
3375 windows.h gets included before w32term.h uses some of its
3376 features, see below.
3378 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3380 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
3382 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
3384 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
3386 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
3387 (ns_select): Return at once if events are held (Bug#12834).
3389 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3391 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3392 Needed following 2012-10-20 change. (Bug#12902)
3394 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3396 * w32proc.c (waitpid): Remove unused label get_result.
3398 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3400 * makefile.w32-in (SYSWAIT_H): New macro.
3401 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3402 ($(BLD)/sysdep.$(O)): Update dependencies.
3404 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3406 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
3407 * callproc.c (relocate_fd): Assume F_DUPFD.
3408 * emacs.c, term.c (O_RDWR): Remove.
3409 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3410 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3411 * nsterm.m: Assume <fcntl.h> exists.
3412 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3413 (create_pty, Fmake_network_process, server_accept_connection)
3414 (wait_reading_process_output, init_process_emacs):
3416 (wait_reading_process_output): Put in a special case for WINDOWSNT
3417 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3418 It's not clear this is needed, but it's a more-conservative change.
3419 (create_process): Assume FD_CLOEXEC.
3420 (create_process, create_pty): Assume O_NOCTTY.
3421 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3422 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3423 Omit if not DOS_NT, since F_GETFL is not defined there.
3424 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3425 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3427 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3428 lack it, since gnulib guarantees this.
3429 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3431 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3433 * w32.c (faccessat): Pretend that directories have the execute bit
3434 set. Emacs expects that, e.g., in files.el:cd-absolute.
3436 * w32proc.c (create_child): Don't clip the PID of the child
3437 process to fit into an Emacs integer, as this is no longer a
3439 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3440 reaping only the process specified by PID argument, if that is
3441 positive. Use PID instead of dead_child to know which process to
3442 reap. Wait for the child to die only if WNOHANG is not in
3444 (sys_select): Don't set dead_child.
3446 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3447 as it is no longer needed.
3449 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3451 (record_child_status_change): Remove the setting of
3452 record_at_most_one_child for the !WNOHANG case.
3454 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3456 Fix problems in ns port found by static checking.
3457 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3458 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3459 not to process group.
3460 (ns_select): Use emacs_write, not write, as that's more robust
3461 in the presence of signals.
3462 (fd_handler:): Check for read errors.
3464 2012-11-16 Glenn Morris <rgm@gnu.org>
3466 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3468 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3470 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3472 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3474 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3475 use the same value of thread handle.
3476 (start_timer_thread): If the timer thread exited (due to error),
3477 clean up by closing the two handles it used. Duplicate the caller
3478 thread's handle here, so it gets duplicated only once, when
3479 launching the timer thread. Set priority of the timer thread, not
3481 (getitimer): Don't duplicate the caller thread's handle here.
3484 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3486 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3489 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3491 Remove no-longer-used pty_max_bytes variable.
3492 * process.c (pty_max_bytes): Remove; unused.
3493 (send_process): Do not set it.
3495 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3497 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3498 Update dependencies.
3500 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3502 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3503 This follows up on the 2012-09-29 patch that removed indirection
3504 for the 'function' field. Reported by Sergey Vinokurov in
3505 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3507 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3509 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3510 different name, as the MS runtime does not have such a function,
3511 and probably never will.) All callers changed. Ignore DIRFD
3512 value if PATH is an absolute file name, to match Posix spec
3513 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3516 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3518 * xdisp.c (echo_area_display, redisplay_internal):
3519 Omit redundant check whether frame_garbaged is set.
3521 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3523 Use faccessat, not access, when checking file permissions (Bug#12632).
3524 This fixes a bug that has been present in Emacs since its creation.
3525 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3526 which must set some sort of record. (Torek's bug report was against
3527 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3528 same common flaw.) See Torek's Usenet posting
3529 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3530 Posted: Fri Apr 8 14:18:56 1983.
3531 * Makefile.in (LIB_EACCESS): New macro.
3533 * callproc.c (init_callproc):
3534 * charset.c (init_charset):
3535 * fileio.c (check_existing, check_executable, check_writable)
3537 * lread.c (openp, load_path_check):
3538 * process.c (allocate_pty):
3540 Use effective UID when checking permissions, not real UID.
3541 * callproc.c (init_callproc):
3542 * charset.c (init_charset):
3543 * lread.c (load_path_check, init_lread):
3544 Test whether directories are accessible, not merely whether they exist.
3545 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3546 * fileio.c (check_existing, check_executable, check_writable)
3548 Use symbolic names instead of integers for the flags, as they're
3550 (check_writable): New arg AMODE. All uses changed.
3551 Set errno on failure.
3552 (Ffile_readable_p): Use faccessat, not stat + open + close.
3553 (Ffile_writable_p): No need to call check_existing + check_writable.
3554 Just call check_writable and then look at errno. This saves a syscall.
3555 dir should never be nil; replace an unnecessary runtime check
3556 with an eassert. When checking the parent directory of a nonexistent
3557 file, check that the directory is searchable as well as writable, as
3558 we can't create files in unsearchable directories.
3559 (file_directory_p): New function, which uses 'stat' on most platforms
3560 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3561 (Ffile_directory_p, Fset_file_times): Use it.
3562 (file_accessible_directory_p): New function, which uses a single
3563 syscall for efficiency.
3564 (Ffile_accessible_directory_p): Use it.
3565 * xrdb.c (file_p): Use file_directory_p.
3566 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3567 * lread.c (openp): When opening a file, use fstat rather than
3568 stat, as that avoids a permissions race. When not opening a file,
3569 use file_directory_p rather than stat.
3570 (dir_warning): First arg is now a usage string, not a format.
3571 Use errno. All uses changed.
3572 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3573 that merely introduced a race.
3574 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3575 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3576 and similarly for the other O_* flags.
3577 * w32.c (sys_faccessat): Rename from sys_access and switch to
3578 faccessat's API. All uses changed.
3579 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3580 (magic_db): Rename from magic_file_p.
3581 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3582 char *, so that we don't have to test for file existence
3583 separately from opening the file for reading. This removes a race
3584 fixes a permission-checking problem, and simplifies the code.
3586 (file_p): Remove; no longer needed.
3588 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3590 Omit glyphs initialization at startup.
3591 * dispnew.c (glyphs_initialized_initially_p): Remove.
3592 (adjust_frame_glyphs_initially): Likewise. Adjust users.
3593 (Fredraw_frame): Move actual code from here...
3594 (redraw_frame): ...to here. Add eassert. Adjust comment.
3595 (Fredraw_display): Use redraw_frame.
3596 * xdisp.c (clear_garbaged_frames): Likewise.
3598 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3600 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3601 passed to pint2str and pint2hrstr to be at most the size of the
3602 frame's decode_mode_spec_buffer. This avoids crashes with very
3603 large values of FIELD_WIDTH argument to decode_mode_spec.
3606 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3608 Fix a race with verify-visited-file-modtime (Bug#12863).
3609 Since at least 1991 Emacs has ignored an mtime difference of no
3610 more than one second, but my guess is that this was to work around
3611 file system bugs that were fixed long ago. Since the race is
3612 causing problems now, let's remove that code.
3613 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3614 whose time stamp is off by no more than a second. Insist that the
3615 file time stamps match exactly.
3617 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3619 * frame.h (struct frame): Convert external_tool_bar member to
3620 1-bit unsigned bitfield.
3621 * termhooks.h (struct terminal): Remove mouse_moved member since
3622 all users are long dead. Adjust comment on mouse_position_hook.
3624 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3626 Simplify by using FOR_EACH_FRAME here and there.
3627 * frame.c (next_frame, prev_frame, other_visible_frames)
3628 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
3629 * w32term.c (x_window_to_scroll_bar): Likewise.
3630 * window.c (window_list): Likewise.
3631 * xdisp.c (x_consider_frame_title): Likewise.
3632 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
3633 * xfns.c (x_window_to_frame, x_any_window_to_frame)
3634 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
3635 * xmenu.c (menubar_id_to_frame): Likewise.
3636 * xselect.c (frame_for_x_selection): Likewise.
3637 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3638 (x_window_to_menu_bar): Likewise.
3639 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3641 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3643 * data.c (Qdefalias_fset_function): Now static.
3645 Another tweak to vectorlike_header change.
3646 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3647 Remove, and replace all uses with ...
3648 (next_in_free_list, set_next_in_free_list):
3649 New functions, which respect C's aliasing rules better.
3651 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3653 * window.c (list4i): Rename from 'quad'. All uses changed.
3654 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3656 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3658 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3659 warning about mixing declarations and code in ISO C90.
3661 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3663 * window.c (Fsplit_window_internal): Set combination limit of
3664 new parent window to t iff Vwindow_combination_limit is t;
3665 fixing a regression introduced with the change from 2012-09-22.
3666 (Fset_window_combination_limit): Fix doc-string.
3668 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3670 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3671 amount when the scroll margins are too large. When scrolling
3672 backwards in the buffer, give up if cannot reach point or the
3673 scroll margin within a reasonable number of screen lines.
3674 Fixes point position in window under scroll-up/down-aggressively when
3675 point is positioned many lines beyond the window top/bottom.
3678 * ralloc.c (relinquish): If real_morecore fails to return memory
3679 to the system, don't crash; instead, leave the last heap
3680 unchanged and return. (Bug#12774)
3682 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3684 * lisp.h (AUTOLOADP): New macro.
3685 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
3686 * data.c (Ffset): Remove special ad-advice-info handling.
3687 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
3689 (Finteractive_form): Simplify.
3690 (Fquo): Don't insist on having at least 2 arguments.
3691 (Qdefalias_fset_function): New var.
3693 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3695 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
3697 * nsfont.m (Qcondensed, Qexpanded): New variables.
3698 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
3699 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
3701 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3703 Fix recently introduced crash on MS-Windows (Bug#12839).
3704 * w32term.h (struct scroll_bar): Use convenient header.

3710 Tweak last vectorlike_header change.
3711 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3712 vectorlike object on the free list. This is introduced to avoid
3713 some (but not all) pointer casting and aliasing problems, see
3714 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3715 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

3719 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3721 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has

3744 * lisp.h (sxhash_combine): New inline function, with the contents
3745 of the old SXHASH_COMBINE.
3746 * profiler.c (hashfn_profiler): Use it, instead of having a
3747 special hash function containing a comparison that always yields 1.
3749 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3751 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3752 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3753 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3756 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3758 * image.c (xpm_make_color_table_h): Fix compiler error because
3759 make_hash_table changed.
3761 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
3763 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3765 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3767 Use ad-hoc comparison function for the profiler's hash-tables.
3768 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3769 (make_log): Use them.
3770 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3771 call Fequal any more.

3780 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
3781 (hash_lookup, hash_remove_from_table): Move assertion checking of
3782 hashfn result here. Check hash-equality before calling cmpfn.

3794 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
3795 value of w32-scroll-lock-modifier is neither nil nor one of the
3796 known key modifiers. (Bug#12806)
3798 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3800 Shrink struct vectorlike_header to the only size field.
3801 * lisp.h (enum pvec_type): Avoid explicit enum member values.
3803 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
3804 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
3805 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
3806 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
3807 information from the vector header. Adjust comment.

3824 (allocate_vector_from_block): Simplify.
3825 (PSEUDOVECTOR_NBYTES): Replace with...

3828 (allocate_vectorlike): Likewise.
3829 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
3830 Add easserts. Adjust XSETPVECTYPESIZE usage.
3831 (allocate_buffer): Use BUFFER_PVEC_INIT.
3832 (live_vector_p): Adjust to match large vector.
3833 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
3834 * buffer.h (struct buffer): Add next member.
3835 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
3837 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

3843 (xvecsize): New command.
3845 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3847 * keyboard.c (event_to_kboard): Do not dereference
3848 frame_or_window field of SELECTION_REQUEST_EVENT
3849 and SELECTION_CLEAR_EVENT events (Bug#12814).
3850 * xterm.h (struct selection_input_event): Adjust comment.
3852 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3854 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3855 such as Scroll Lock, if the respective keys are treated as
3856 function keys, not as modifiers. This avoids destroying non-ASCII
3857 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3859 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3861 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3863 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3865 Restore some duplicate definitions (Bug#12814).
3866 This undoes part of the 2012-11-03 changes. Some people build
3867 with plain -g rather than with -g3, and they need the duplicate
3868 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3869 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3870 Define as macros, as well as as enums or as constants.
3872 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
3874 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
3875 to keypad keys (Bug#12816).
3877 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3879 Minor adjustments of recently-changed frame functions.
3880 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3881 known to be a frame (we're in the FRAMEP branch).
3882 * lisp.h (Qframep): Remove decl. frame.h declares this.
3883 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3884 since they're meant for Lisp fixnum values.
3886 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3888 * window.c (Fwindow_combination_limit): Revert to the only
3889 required argument and adjust docstring as suggested in
3890 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3891 by Martin Rudalics <rudalics@gmx.at>.
3893 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3895 Widely used frame validity and checking functions.
3896 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
3897 * frame.c (decode_live_frame, decode_any_frame): New functions.
3898 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
3899 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
3900 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
3901 (Fframe_pointer_visible_p): Use decode_any_frame.

3907 (frame_buffer_list, frame_buffer_predicate): Remove.
3908 * lisp.h (frame_buffer_predicate): Remove prototype.
3909 * buffer.c (Fother_buffer): Use decode_any_frame.
3910 * xdisp.c (Ftool_bar_lines_needed): Likewise.
3911 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3912 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3913 (Fclose_font, Ffont_info): Use decode_live_frame.
3914 * fontset.c (check_fontset_name): Likewise.
3915 * terminal.c (Fframe_terminal): Likewise.
3916 * w32fns.c (check_x_frame): Likewise.
3917 * window.c (Fminibuffer_window, Fwindow_at)
3918 (Fcurrent_window_configuration): Likewise.
3919 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
3920 Likewise. Allow zero number of arguments. Adjust docstring.
3921 * dispnew.c (Fredraw_frame): Likewise.
3922 * xfaces.c (frame_or_selected_frame): Remove.
3923 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3924 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3925 (Fframe_face_alist): Use decode_live_frame.
3926 * xfns.c (check_x_frame): Likewise.
3928 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3930 * window.c (quad): New function.
3931 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3932 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3933 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3934 (Fwindow_line_height): Use it.
3935 (Fwindow_fringes): Use list3.
3936 (Fwindow_scroll_bars): Use list4.
3937 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3938 (Fwindow_combination_limit): Allow zero number of arguments.
3940 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3942 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3944 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3945 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3946 file descriptor 2 for standard error. (Bug#12805)
3948 2012-11-05 Chong Yidong <cyd@gnu.org>
3950 * process.c (wait_reading_process_output): Revert previous change.
3952 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3954 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3955 This removes code that has been obsolete since around 1990.
3956 * callproc.c (Fcall_process):
3958 * process.c (create_process):
3959 * term.c (dissociate_if_controlling_tty):
3960 Assume setsid exists.
3961 * callproc.c (child_setup): Assume setpgid exists and behaves as
3962 per POSIX.1-1988 or later.
3963 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3964 * emacs.c (shut_down_emacs):
3965 * sysdep.c (sys_suspend, init_foreground_group):
3966 Assume getpgrp behaves as per POSIX.1-1998 or later.
3967 * msdos.c (setpgrp): Remove.
3968 (tcgetpgrp, setpgid, setsid): New functions.
3969 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3970 * term.c (no_controlling_tty): Remove; unused.
3971 * w32proc.c (setpgrp): Remove.
3972 (setsid, tcgetpgrp): New functions.
3974 Simplify by assuming __fpending.
3975 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3976 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3977 Do not assume that __fpending's result fits in int.
3979 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3981 Remove EMACS_OUTQSIZE+sleep hack.
3982 * dispnew.c (update_frame_1): Remove hack for terminals slower
3983 than 2400 bps, which throttled Emacs by having it sleep.
3984 This code hasn't worked since at least 2007, when the multi-tty stuff
3985 was added, and anyway those old terminals are long dead.
3986 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3987 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3989 Fix data-loss with --version (Bug#9574).
3990 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3991 as we can't assume that emacs_strerror is initialized, and strerror
3992 is good enough here.
3993 (main): Invoke atexit earlier, to catch earlier instances of
3994 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3996 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3998 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3999 (keyDown): Remap keypad keys to X11 virtual key codes.
4001 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
4003 Fix data-loss with --batch (Bug#9574).
4004 * emacs.c: Include <close-stream.h>.
4005 (close_output_streams): New function.
4006 (main): Pass it to atexit, so that Emacs closes stdout and stderr
4007 and handles errors appropriately.
4008 (Fkill_emacs): Don't worry about flushing, as close_output_stream
4011 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
4012 The symptom is a diagnostic "GLib-WARNING **: In call to
4013 g_spawn_sync(), exit status of a child process was requested but
4014 SIGCHLD action was set to SIG_IGN and ECHILD was received by
4015 waitpid(), so exit status can't be returned." The diagnostic
4016 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
4017 The real bug is a race condition between Emacs and glib: Emacs
4018 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
4019 so that glib can't find it. Work around the bug by invoking
4020 waitpid only on subprocesses that Emacs itself creates.
4021 * process.c (create_process, record_child_status_change):
4022 Don't use special value -1 in pid field, as the caller now must
4023 know the pid rather than having the callee infer it.
4024 The inference was sometimes incorrect anyway, due to another race.
4025 (create_process): Set new 'alive' member if child is created.
4026 (process_status_retrieved): New function.
4027 (record_child_status_change): Use it.
4028 Accept negative 1st argument, which means to wait for the
4029 processes that Emacs already knows about. Move special-case code
4030 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
4031 processes that have already been waited for, by testing and
4032 clearing new 'alive' member.
4033 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
4034 now does this internally.
4035 (handle_child_signal): Let record_child_status_change do all
4036 the work, since we do not want to reap all exited child processes,
4037 only the child processes that Emacs itself created.
4038 * process.h (Lisp_Process): New boolean member 'alive'.
4040 Omit duplicate definitions no longer needed with gcc -g3.
4041 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
4042 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
4043 Define only as macros. There's no longer any need to also define
4044 these symbols as enums or as constants, since we now assume
4045 gcc -g3 when debugging.
4047 2012-11-03 Eli Zaretskii <eliz@gnu.org>
4049 * lisp.mk: Adjust comments to the fact that term/internal is now
4050 loaded from loadup.el.
4052 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
4053 (msdos_fatal_signal): New function.
4054 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
4057 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
4058 for GCC versions before 4.
4059 (emacs_raise): Define to call msdos_fatal_signal.
4061 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
4062 iterator when starting in the middle of a display or overlay
4065 2012-11-03 Chong Yidong <cyd@gnu.org>
4067 * process.c (wait_reading_process_output): Clean up the last
4070 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
4072 * process.c (wait_reading_process_output): Avoid a race condition
4073 with SIGIO delivery (Bug#11536).
4075 2012-11-03 Chong Yidong <cyd@gnu.org>
4077 * buffer.c (cursor_type): Untabify docstring.
4079 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4081 * frame.h (struct frame): Drop can_have_scroll_bars member
4082 which is meaningless for a long time. Adjust comments.
4083 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
4084 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
4086 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4088 * window.c (decode_next_window_args): Update window arg after
4089 calling decode_live_window and so fix crash reported at
4090 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
4091 by Juanma Barranquero <lekktu@gmail.com>.
4092 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
4093 * font.c (Ffont_at): Likewise.
4095 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
4097 * widget.c (resize_cb): New function.
4098 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
4099 (EmacsFrameResize): Check if all is up to date before changing frame
4102 2012-11-02 Eli Zaretskii <eliz@gnu.org>
4104 Implement backtrace output for fatal errors on MS-Windows.
4105 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
4106 (BACKTRACE_LIMIT_MAX): New macro.
4107 (w32_backtrace): New function.
4108 (emacs_abort): Use w32_backtrace when the user chooses not to
4109 attach a debugger. Update the text of the abort dialog.
4111 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4113 Window-related stuff cleanup here and there.
4114 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
4115 Use decode_any_window.
4116 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
4117 * xdisp.c (Fformat_mode_line): Likewise.
4118 * font.c (Ffont_at): Use decode_live_window.
4119 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
4120 * window.c (decode_next_window_args): Likewise.
4121 (decode_any_window): Remove static.
4122 * window.h (decode_any_window): Add prototype.
4123 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
4124 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
4127 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4129 Remove pad from struct input_event.
4130 * termhooks.h (struct input_event): Remove padding field.
4132 * keyboard.c (event_to_kboard): Simplify because frame_or_window
4133 member is never cons for a long time. Adjust comment.
4134 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
4135 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
4136 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
4137 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
4139 2012-11-01 Eli Zaretskii <eliz@gnu.org>
4141 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
4143 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
4145 Fix crash when using Emacs as commit editor for git (Bug#12697).
4146 * callproc.c (setpgrp): Remove macro, as we now use setpgid
4147 and it is configured in conf_post.h.
4148 (Fcall_process): Don't invoke both setsid and setpgid; the former
4149 is enough, if it exists.
4150 * callproc.c (Fcall_process, child_setup):
4151 * process.c (create_process): Use setpgid.
4152 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
4154 * dispnew.c (init_display): Initialize the foreground group
4155 if we are running a tty display.
4156 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
4157 * lisp.h (init_foreground_group): New decl.
4158 * sysdep.c (inherited_pgroup): New static var.
4159 (init_foreground_group, tcsetpgrp_without_stopping)
4160 (narrow_foreground_group, widen_foreground_group): New functions.
4161 (init_sys_modes): Narrow foreground group.
4162 (reset_sys_modes): Widen foreground group.
4164 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
4166 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
4168 2012-10-31 Martin Rudalics <rudalics@gmx.at>
4170 * minibuf.c (read_minibuf): Restore current buffer since
4171 choose_minibuf_frame calling Fset_frame_selected_window may
4172 change it (Bug#12766).
4174 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
4176 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
4178 2012-10-30 Kenichi Handa <handa@gnu.org>
4180 * font.c (Ffont_at): If WINDOW is specified and it is not
4181 displaying the current buffer, signal an error.
4183 2012-10-29 Daniel Colascione <dancol@dancol.org>
4185 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
4186 In preparation for fixing bug#12739, move these functions from
4189 * coding.h, coding.c: ... to here, and compile them only when
4190 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
4191 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
4193 2012-10-28 Eli Zaretskii <eliz@gnu.org>
4195 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
4196 (timer_loop, getitimer, setitimer): Use it instead of
4197 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
4199 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
4202 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
4204 * nsterm.m (NO_APPDEFINED_DATA): New define.
4205 (last_appdefined_event_data): New variable
4206 (last_appdefined_event): Remove.
4207 (ns_select): Initialize t from last_appdefined_event_data instead
4208 of [last_appdefined_event data1].
4209 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
4210 remove last_appdefined_event (Bug#12698).
4212 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
4214 * frame.c (x_set_font): Catch internal error.
4216 2012-10-27 Eli Zaretskii <eliz@gnu.org>
4218 Avoid overflow in w32 implementation of interval timers.
4219 When possible, for ITIMER_PROF count only times the main thread
4221 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
4222 'volatile ULONGLONG' types. All the other data which was
4223 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
4224 (GetThreadTimes_Proc): New typedef.
4225 (w32_get_timer_time): New function, returns a suitable time value
4227 (timer_loop): Enter critical section when accessing ULONGLONG
4228 values of the itimer_data struct, as these accesses are no longer
4229 atomic. Call 'w32_get_timer_time' instead of 'clock'.
4230 Remove unused variable.
4231 (init_timers): Initialize s_pfn_Get_Thread_Times.
4232 (start_timer_thread): Don't assign itimer->caller_thread here.
4233 (getitimer): Assign itimer->caller_thread here.
4234 (setitimer): Always call getitimer to get the value of ticks_now.
4235 (sys_spawnve): Avoid compiler warning about format mismatch.
4237 2012-10-26 Eli Zaretskii <eliz@gnu.org>
4239 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
4240 mouse movement events if the menu bar is active. This avoids
4241 producing a busy "hour-glass" cursor by Windows if the mouse
4242 pointer is positioned over a tooltip shown for some menu item.
4244 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
4246 Don't assume process IDs fit in int.
4247 * emacs.c (shut_down_emacs) [!DOS_NT]:
4248 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
4249 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
4250 Use pid_t, not int, to store process IDs, as 'int'
4251 is not wide enough on a few platforms (e.g., AIX and IRIX).
4253 2012-10-23 Kenichi Handa <handa@gnu.org>
4255 The following change is to make face-font-rescale-alist work
4256 correctly for non-ASCII fonts.
4258 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
4259 (font_open_for_lface): Handle Vface_font_rescale_alist.
4261 2012-10-23 Chong Yidong <cyd@gnu.org>
4263 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
4265 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

4269 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
4271 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
4274 2012-10-21 Glenn Morris <rgm@gnu.org>
4276 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
4278 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
4280 Port to OpenBSD 5.1.
4281 * frame.c (Fmouse_position, Fmouse_pixel_position):
4282 * xdisp.c (produce_stretch_glyph):
4283 Declare local vars only when they're needed.
4284 This is clearer and avoids a warning on OpenBSD about unused vars.

4286 This is safer, and avoids OpenBSD warnings about unused vars.
4287 * keyboard.c (record_menu_key): Remove unnecessary decl.
4288 (poll_timer): Define only if POLL_FOR_INPUT is defined.
4289 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
4290 as our definition clashes with OpenBSD's.
4291 * xfaces.c (load_face_colors, check_lface_attrs)
4292 (get_lface_attributes_no_remap, get_lface_attributes)
4293 (lface_fully_specified_p, x_supports_face_attributes_p)
4294 (tty_supports_face_attributes_p, face_fontset, realize_face)
4295 (realize_x_face, realize_tty_face):
4296 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
4297 merely Lisp_Object *. This is more informative and avoids
4298 a warning on OpenBSD about accessing beyond an object's size.
4300 2012-10-20 Chong Yidong <cyd@gnu.org>
4302 * lread.c (Fload): Doc fix (Bug#12592).

4328 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
4329 (staticpro): If we run out of staticpro slots, die with an
4330 informative error instead of just calling emacs_abort.
4332 2012-10-18 Martin Rudalics <rudalics@gmx.at>
4334 Fix two flaws reported by Dmitry Antipov.

4591 (get_input_pending): Remove first argument, since it was always
4592 the same pointer-to-int (now pointer-to-boolean) &input_pending,
4593 and behave as if it had that value. Return new value of
4594 input_pending. All callers changed.
4595 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
4596 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

4618 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
4619 Don't include termopts.h.
4621 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
4623 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
4625 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
4627 * commands.h (immediate_quit): Remove duplicate decl.
4629 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
4631 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

4634 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
4636 2012-10-09 Eli Zaretskii <eliz@gnu.org>
4638 * w32fns.c (w32_last_error): Change the return value to DWORD, to
4639 match what GetLastError returns. Explain why the function is
4642 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
4643 'is_tooltip_frame', to avoid confusion with its global namesake.
4645 2012-10-08 Daniel Colascione <dancol@dancol.org>
4647 * xdisp.c (start_hourglass): Call w32_note_current_window when
4648 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
4649 build that caused Emacs to display the hourglass cursor forever.
4651 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
4652 which is broken under remote desktop, calculate the number of
4653 colors available for a display based on the display's number of
4654 planes and number of bits per pixel per plane. (bug#10397).
4656 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
4658 * nsfont.m (Vfonts_in_cache): New variable.
4659 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
4660 are used. Add cached fonts to Vfonts_in_cache.
4661 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
4663 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
4665 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
4667 (FONT_H): Define after FRAME_H.
4668 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
4669 Update dependencies.
4671 * w32term.c: Remove leftover declaration of keyboard_codepage.
4673 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4675 * makefile.w32-in (FONT_H): Add $(FRAME_H).
4676 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
4677 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
4678 (GLOBAL_SOURCES): Add cygw32.c.
4679 ($(BLD)/unexw32.$(O)):
4681 ($(BLD)/w32console.$(O)):
4682 ($(BLD)/w32fns.$(O)):
4683 ($(BLD)/w32heap.$(O)):
4684 ($(BLD)/w32menu.$(O)):
4685 ($(BLD)/w32proc.$(O)): Add w32common.h.
4687 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
4689 (x_to_w32_color): Don't modify the argument, modify a copy instead.
4691 2012-10-08 Daniel Colascione <dancol@dancol.org>
4693 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
4694 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
4695 accidental message numbering hole. Change other messages to
4698 * w32select.h (HAVE_W32SELECT): Remove.
4700 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
4701 w32common.h instead of w32heap.h.
4703 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
4704 (get_allocation_unit, get_processor_type, get_w32_major_version)
4705 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4706 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4707 (OS_NT, os_subtype, cache_system_info): Move declarations to
4710 * w32heap.c: Include w32common.h.
4711 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
4712 (w32_minor_version, w32_build_number, w32_subtype):
4713 Remove duplicate definitions.
4715 * w32fns.c: Include w32common.h; include w32heap.h only in
4718 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
4719 Use `report_file_error' instead of `error' in order to better
4720 inform users of what went wrong. Increase NTGUI_UNICODE file
4721 dialog box file name length to 32k, the maximum allowed by the NT
4724 * w32common.h: New file.
4725 (ROUND_UP, ROUND_DOWN, get_page_size)
4726 (get_allocation_unit, get_processor_type, get_w32_major_version)
4727 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4728 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4729 (OS_NT, os_subtype, cache_system_info): Move here.
4731 * unexw32.c, unexcw.c: Include w32common.h.
4733 * emacs.c (main): Use (defined (WINDOWSNT) || defined
4734 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
4735 to call syms_of_w32select.
4737 * cygw32.h: Remove obsolete EXFUN declarations.
4739 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
4741 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
4742 of w32inevt.o from SOME_MACHINE_OBJECTS.
4744 2012-10-08 Daniel Colascione <dancol@dancol.org>
4746 * image.c: Permanent fix for JPEG compilation issue --- limit
4747 jpeglib `boolean' redefinition to Cygwin builds.
4749 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4751 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
4753 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
4756 2012-10-08 Daniel Colascione <dancol@dancol.org>
4758 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4759 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
4760 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
4761 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
4762 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
4763 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4764 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4765 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4766 now a supported configuration.
4768 * Makefile.in: consolidate image variables into LIBIMAGE; add
4769 W32_OBJ and W32_LIBS. Compile new files.
4772 (_DebPrint) declare tracing facility for W32 debugging. We need
4773 to unify tracing later.
4775 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4776 unconditional use of W32 Unicode functions. Cygwin runs only on
4777 100% Unicode operating systems.
4779 * cygw32.c: New file. Define Cygwin-specific facilities.
4780 (Fcygwin_convert_path_to_windows)
4781 (Fcygwin_convert_path_from_windows): New user functions for
4782 accessing Cygwin path-munging routines.
4784 * cygw32.h: New file.
4785 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4786 UTF-16LE strings temporarily inside non-Lisp-visible string
4789 (w32_strerror): Just what it says on the tin.
4791 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4792 also run for Cygwin; both systems have the same problem with using
4793 GUI facilities in a forked child. Also call syms_of_cygw32,
4794 syms_of_w32select in correct places.
4796 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4797 needs fork-then-exec for daemon launching.
4799 * font.h: Include frame.h.
4801 * image.c: Use the image library cache machinery only when we're
4802 compiling for native WINDOWSNT; Cygwin can use shared libraries
4803 like any other Unixlike system.
4805 * keyboard.c: Clarify a comment regarding the input loop.
4807 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4808 functions directly instead of trying to detect at runtime that our
4809 host operating system supports them. We make this change for two
4810 reasons: Cygwin lacks support for the multibyte character
4811 conversion functions used by the legacy menu code, and Cygwin
4812 never needs to rely on non-Unicode APIs.
4814 * unexw32.c (hinst): Declare extern.
4816 * w32.c: Change header order;
4817 (w32_strerror): Move to w32fns.c because we need it for
4818 non-WINDOWSNT builds.
4820 * w32.h: Add #error macro to make sure we don't include w32.h for
4821 Cygwin builds. Remove w32select declarations.
4823 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4824 w32fns.c. w32console.c is WINDOWSNT-only.
4826 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4827 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4829 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4830 (w32_major_version, w32_minor_version, w32_build_number)
4831 (os_subtype, sound_type): Define here
4832 (w32_defined_color): Make color parameter const for consistency
4833 with other _defined_color functions.
4834 (w32_createwindow): Unconditionally call w32_init_class instead of
4835 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4836 through the code is complex and unnecessary because class
4837 registration is practically free.
4838 (w32_name_of_message): New EMACSDEBUG-only function.
4839 (Fset_message_beep): Move here
4840 (Fx_open_connection): Require that the display name for Windows be
4841 "w32" for consistency, emacsclient disambiguation, and maybe, one
4842 day, multi-window-system support.
4843 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4844 Cygwin files for W32 GUI facilities, since these clearly don't
4845 expect Cygwin names.
4846 (_DebPrint): Define.
4847 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4848 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4849 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4850 (w32_last_error): Remove.
4852 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4854 * w32heap.c (syspage_mask): Declare here.
4855 (cache_system_info): Remove.
4857 * w32inevt.c (faked_key): Define globally, not statically.
4858 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4859 (w32_console_toggle_lock_key): Move to w32fns.c.
4861 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4863 * w32proc.c (_DebPrint): Move to w32fns.c.
4864 * w32select.c: Include string.h, stdio.h for Cygwin.
4865 * w32select.h: New File.
4867 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4869 (w32_message_fd): New variable. Under Cygwin, holds the file
4870 descriptor the system used to tell us about pending thread
4873 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4874 that prevented compilation under non-WINDOWSNT systems.
4876 (w32_initialize): Open /dev/windows and assign it to
4877 w32_message_fd. Provide w32 feature.
4879 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4880 (WM_EMACS_INPUT_READY): add.
4881 (prepend_msg, w32_message_fd): Declare globally.
4884 (keyboard_handle): Use only when WINDOWSNT.
4885 (notify_msg_ready): New function. Posts a message to the main
4886 thread's message queue under CYGWIN, which wakes up the main
4887 thread from select(2) by making the /dev/windows file descriptor
4888 ready. Under WINDOWSNT, it sets an event the same way the old
4891 (post, prepend_msg): Actually call notify_msg_ready instead of
4892 setting the input event directly.
4894 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4896 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4897 but it still has blocs in it, don't return it to the system,
4898 instead of aborting. (Bug#12402)
4900 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4902 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4904 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4905 MAC_OS_X_VERSION_10_6.
4906 (syms_of_nsterm): Remove comment about Panther and above for
4908 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
4909 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
4910 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4912 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4913 MAC_OS_X_VERSION_10_4.
4915 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4916 MAC_OS_X_VERSION_10_2.
4918 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4920 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4921 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4923 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4924 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4925 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4926 Remove ns_in_resize check.
4927 (ns_clear_frame_area): Remove resize handle code.
4929 * nsfns.m (ns_in_resize): Remove.
4930 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4931 Remove ns_in_resize check.
4933 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4935 Improve sys_siglist detection.
4936 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4937 defined as a macro, as is done in Solaris.
4938 (sys_siglist_entries): New macro.
4939 (save_strsignal): Use it.
4940 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4941 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4943 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4945 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4946 fullscreen/Fullscreen.
4948 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4949 tobar_height is new.
4951 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4952 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4953 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4954 (windowDidResize:): Check for correct window if old style fullscreen.
4955 Capitalize word in comment. Remove incorrect comment.
4956 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4957 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4958 error in drawing background.
4959 (toggleFullScreen:): Remove comment. Rearrange calls.
4960 Set toolbar values to zero, save old height in tobar_height.
4961 Restore tool bar height when leaving fullscreen.
4962 (canBecomeMainWindow): New function.
4964 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4966 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4968 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4970 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4972 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4973 that time stamps of directories could also be changed.
4974 Don't request the too broad GENERIC_WRITE, only the more restrictive
4975 FILE_WRITE_ATTRIBUTES access rights.
4977 * fileio.c (Fset_file_times): Special-case ignoring errors for
4978 directories only on MSDOS, not on MS-Windows.
4980 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4982 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4984 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4986 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4987 see whether CreateFile failed.
4989 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4991 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4992 to avoid similar races.
4993 * keyboard.c (pending_signals): Now bool, not int.
4995 Port timers to OpenBSD, plus check for timer failures.
4996 OpenBSD problem reported by Han Boetes.
4997 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4999 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
5000 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
5001 like OpenBSD, which has timer_settime but does not declare it.
5002 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
5003 whether to use itimerspec-related primitives. All uses of
5004 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
5006 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5008 * profiler.c (handle_profiler_signal): Fix a malloc race
5009 that caused Emacs to hang on Fedora 17 when profiling Lisp.
5011 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
5013 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
5015 2012-10-02 Eli Zaretskii <eliz@gnu.org>
5017 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
5018 consistent with the change in return value of 'safe_strsignal'.
5020 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5022 Prefer plain 'static' to 'static inline' (Bug#12541).
5023 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
5024 (bidi_set_sor_type, bidi_push_embedding_level)
5025 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
5026 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
5027 (bidi_cache_search, bidi_cache_ensure_space)
5028 (bidi_cache_iterator_state, bidi_cache_find)
5029 (bidi_peek_at_next_level, bidi_set_paragraph_end)
5030 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5031 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
5032 Now 'static', not 'static inline'.
5034 Count overruns when profiling; change units to ns.
5035 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
5036 Give extra weight to samples after overruns, to attempt to count
5037 the time more accurately.
5038 (setup_cpu_timer): Change sampling interval units from ms to ns, since
5039 the underlying primitives nominally do ns.
5040 (Fprofiler_cpu_start): Document the change. Mention that
5041 the sampling intervals are only approximate.
5043 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5045 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
5047 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
5048 case for the special 0 coding-system.
5050 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
5051 (Fmake_overlay): Remove redundant tests.
5052 (fix_start_end_in_overlays): Remove redundant recentering.
5054 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
5056 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
5057 Update dependencies.
5059 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5061 Fix a malloc race condition involving strsignal.
5062 A signal can arrive in the middle of a malloc, and Emacs's signal
5063 handler can invoke strsignal, which can invoke malloc, which is
5064 not portable. This race condition bug makes Emacs hang on GNU/Linux.
5065 Fix it by altering the signal handler so that it does not invoke
5067 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
5068 * process.c (status_message): Use const pointer, in case strsignal
5069 is #defined to safe_strsignal.
5070 * sysdep.c (sys_siglist, init_signals): Always define and
5071 initialize a substitute sys_siglist if the system does not define
5072 one, even if HAVE_STRSIGNAL.
5073 (safe_strsignal): Rename from strsignal. Always define,
5074 using sys_siglist. Return a const pointer.
5075 * syssignal.h (safe_strsignal): New decl.
5076 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
5078 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5080 * w32proc.c (timer_loop): Fix code that waits for timer
5081 expiration, to avoid high CPU usage.
5083 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
5085 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
5086 (sweep_weak_table): Remove redundant prototypes.
5088 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
5090 * emacs.c: Move the inclusion of TERM_HEADER after including
5091 windows.h on WINDOWSNT. This avoids compilation problems with
5094 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5096 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
5097 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
5098 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
5099 as the previous version used 'void *'.
5101 * ralloc.c (ROUNDUP): Fix last change.
5102 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
5105 * w32proc.c <disable_itimers>: New static flag.
5106 (init_timers): Initialize it to zero, after creating the critical
5107 sections used by the timer threads.
5108 (term_timers): Set to 1 before deleting the critical sections.
5109 (getitimer, setitimer): If disable_itimers is non-zero, return an
5110 error indication without doing anything. Reported by Fabrice
5111 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
5112 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
5114 [!HAVE_SETITIMER]: Behave as the previous version that didn't
5117 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
5118 term_ntproc after all the other bookkeeping, to get timers working
5119 as long as possible.
5121 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5123 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
5124 Suggested by Juri Linkov in
5125 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
5127 Prefer plain 'static' to 'static inline' (Bug#12541).
5128 With static functions, modern compilers inline pretty well by
5129 themselves; advice from programmers often hurts as much as it helps.
5130 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
5131 this change shrinks the text size of the Emacs executable by 1.1%
5132 without affecting CPU significantly in my benchmark.

5213 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
5215 Revert the FOLLOW-SYMLINKS change for file-attributes.
5216 Doing it right would require several changes to Tramp, and there's
5217 not enough time to get that tested before the freeze today.
5218 * dired.c (directory_files_internal, Ffile_attributes):
5221 * frame.c (x_report_frame_params): Port better to wider ints.
5222 Do not assume that EMACS_UINT is the same width as uprintmax_t,

5260 * vm-limit.c (lim_data): Now size_t.
5261 (check_memory_limits): Adjust prototypes of real_morecore and
5262 __morecore to receive argument of type ptrdiff_t. Use size_t for

5288 * frame.c (x_report_frame_params): Use EMACS_UINT for the return
5289 value of FRAME_X_WINDOW, to fit a 64-bit pointer on 64-bit Windows

5318 (struct itimer_data): New definition.
5319 (ticks_now, real_itimer, prof_itimer, clocks_min, crit_real)

5331 Windows-specific code to display the hourglass mouse pointer is no
5333 (w32_wnd_proc): Remove code that handled the WM_TIMER message due
5334 to hourglass timer expiration.

5415 Profiler improvements: more-accurate timers, overflow checks.
5416 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
5417 signal.h, setjmp.h. Include systime.h instead.
5418 (saturated_add): New function.

5425 All uses changed to store the new value.
5426 (handle_profiler_signal): Rename from sigprof_handler_1,
5427 for consistency with other handlers. Do not check whether
5428 cpu_log is a hash-table if garbage collecting, since it
5429 doesn't matter in that case.

5431 for consistency with other handlers.
5432 (setup_cpu_timer): New function, with much of what used to be in
5433 Fprofiler_cpu_start. Check for out-of-range argument.
5434 Prefer timer_settime if available, and prefer
5435 thread cputime clocks, then process cputime clocks, then
5436 monotonic clocks, to the old realtime clock. Use make_timeval
5437 to round more-correctly when falling back to setitimer.
5438 (Fprofiler_cpu_start): Use it.
5439 (Fprofiler_cpu_stop): Prefer timer_settime if available.
5440 Don't assume that passing NULL as the 2nd argument of setitimer
5441 is the same as passing a pointer to all-zero storage.
5442 Ignore SIGPROF afterwards.
5443 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
5444 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
5445 non-fatal signal handlers. Ignore SIGPROF on startup.
5446 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
5447 in profiler.c, since sysdep.c now uses it.
5449 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

5505 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
5506 Since this stuff is now private to charset.c, there's no need for
5507 a public macro and no need to inline by hand.

5535 2012-09-25 Eli Zaretskii <eliz@gnu.org>
5536 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
5538 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
5540 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
5542 Prefer POSIX timers if available.
5543 They avoid a race if the timer is too close to the current time.
5544 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
5545 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
5546 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
5548 2012-09-25 Eli Zaretskii <eliz@gnu.org>
5550 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
5551 CHAR_STRING_ADVANCE.
5552 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
5553 STRING_CHAR_ADVANCE.
5555 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
5557 Move Vlibrary_cache to emacs.c and reset before dumping.
5559 * lisp.h (reset_image_types): Declare.
5560 [WINDOWSNT] (Vlibrary_cache): Declare.
5562 * image.c (reset_image_types): New function.
5564 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.
5565 (syms_of_emacs) [WINDOWSNT] <Vlibrary_cache>: Initialize and staticpro.

5571 * w32.h (Vlibrary_cache): Do not declare.
5573 2012-09-25 Eli Zaretskii <eliz@gnu.org>
5575 * w32proc.c (sys_signal): Handle all signals defined by the
5576 MS-Windows runtime, not just SIGCHLD. Actually install the signal
5577 handlers for signals supported by Windows. Don't override
5578 term_ntproc as the handler for SIGABRT.
5579 (sigaction): Rewrite to call sys_signal instead of duplicating its
5581 (sys_kill): Improve commentary.
5583 * w32.c (term_ntproc): Accept (and ignore) one argument, for
5584 consistency with a signature of a signal handler. All callers
5586 (init_ntproc): Accept an argument DUMPING. If dumping, don't
5587 install term_ntproc as a signal handler for SIGABRT, as that
5588 should be done by the dumped Emacs.
5590 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
5592 * w32select.c (term_w32select): Protect against repeated
5593 invocation by setting clipboard_owner to NULL after calling
5596 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
5597 and term_ntproc to their modified signatures.
5599 * character.c (char_string, string_char): Remove calls to
5600 MAYBE_UNIFY_CHAR. See the discussion starting at
5601 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
5604 2012-09-25 Chong Yidong <cyd@gnu.org>
5606 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
5608 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
5610 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
5611 when encountering an unknown bytecode.
5613 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
5615 image.c, indent.c: Use bool for booleans.
5616 * dispextern.h (struct image_type): Members valid_p, load, init
5617 now return bool, not int. All uses changed.
5618 * image.c: Omit unnecessary static decls.
5619 (x_create_bitmap_mask, x_build_heuristic_mask):
5620 Return void, not int, since callers don't care about the return value.

5649 Use bool for booleans.
5651 2012-09-24 Chong Yidong <cyd@gnu.org>
5653 * chartab.c (Fset_char_table_default): Obsolete function removed.
5655 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5657 Move pid_t related decls out of lisp.h.
5658 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
5659 (interruptible_wait_for_termination):
5660 Move these decls from lisp.h to syswait.h, since they use pid_t.
5661 Needed on FreeBSD; see Herbert J. Skuhra in
5662 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
5663 * callproc.c: Include syswait.h.

5681 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
5682 * xfns.c (Fx_show_tip) [USE_GTK]:
5683 Use bool for boolean.
5684 * gtkutil.c (xg_update_frame_menubar):
5685 * xmenu.c (update_frame_menubar):
5686 Return void, not int, since caller ignores return value.
5687 * gtkutil.c (xg_change_toolbar_position):
5690 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5692 * makefile.w32-in (BLOCKINPUT_H): Remove.

5709 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5711 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5712 fatal_error_backtrace.
5714 * w32proc.c (sys_kill): Undo last change: don't do anything when
5715 invoked to deliver SIGABRT to our own process. This is now
5716 handled by emacs_raise.
5718 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5720 * w32term.c (w32_read_socket): Remove leftover reference to
5721 interrupt_input_pending.
5723 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5725 Do not use SA_NODEFER.
5726 Problem reported by Dani Moncayo in
5727 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5729 * sysdep.c (emacs_abort): Do not reset signal handler.
5730 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5731 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5732 wanted even on POSIXish hosts, and it doesn't work on Windows.
5734 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5736 * xterm.c (x_term_init): Call fixup_locale before and after calling
5737 gtk_init (Bug#12392).
5739 2012-09-23 Chong Yidong <cyd@gnu.org>
5741 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5742 Vdynamic_library_alist.
5744 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5745 (Fgnutls_available_p): Caller changed.
5747 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5748 (Flibxml_parse_xml_region): Likewise.
5750 * dispextern.h (struct image_type): Remove arg from init function.
5752 * image.c (Finit_image_library, lookup_image_type)
5753 (define_image_type): Remove now-unneeded second arg.
5754 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5755 (init_tiff_functions, init_gif_functions, init_svg_functions):
5756 Arglist and w32_delayed_load calling convention changed.
5757 (gs_type): Remove init_gs_functions; there is no such function.
5758 (valid_image_p, make_image): Fix caller to lookup_image_type.
5760 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5762 Simplify and avoid signal-handling races (Bug#12471).
5764 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5765 Avoid recursive loop if there's a fatal error in the function itself.
5766 * atimer.c (pending_atimers):
5767 * blockinput.h: Don't include "atimer.h"; no longer needed.
5768 (interrupt_input_pending): Remove. All uses removed.
5769 pending_signals now counts both atimers and ordinary interrupts.
5770 This is less racy than having three separate pending-signal flags.
5771 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5773 Rename from their upper-case counterparts BLOCK_INPUT,
5774 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5775 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5776 This makes it easier to access volatile variables more accurately.
5777 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5778 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5779 that's more reliable if the code is buggy and sets
5780 interrupt_input_blocked to a negative value. All uses changed.
5781 * atimer.c (deliver_alarm_signal):
5782 Remove. No need to deliver this to the parent; any thread can
5783 handle this signal now. All uses replaced by underlying handler.
5784 * atimer.c (turn_on_atimers):
5785 * dispnew.c (handle_window_change_signal):
5786 * emacs.c (handle_danger_signal):
5787 * keyboard.c (kbd_buffer_get_event):
5788 Don't reestablish signal handler; not needed with sigaction.
5789 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5791 Rework to avoid unnecessary accesses to volatile variables.
5792 (UNBLOCK_INPUT_TO): Now a function.
5793 (totally_unblock_input, unblock_input): New decls.
5794 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5795 (init_data): Remove. Necessary stuff now done in init_signal.
5796 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5797 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5798 (fatal_error_code): Remove; no longer needed.
5799 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5800 it doesn't always backtrace. All uses changed. No need to reset
5801 signal to default, since sigaction and/or die does that for us now.
5802 Use emacs_raise (FOO), not kill (getpid (), FOO).
5803 (main): Check more-accurately whether we're dumping.
5804 Move fatal-error setup to sysdep.c
5805 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5806 * gtkutil.c (xg_get_file_name, xg_get_font):
5807 Remove no-longer-needed signal-mask manipulation.
5808 * keyboard.c, process.c (POLL_FOR_INPUT):
5809 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5810 * keyboard.c (read_avail_input): Remove.
5811 All uses replaced by gobble_input.
5812 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5813 (kbd_buffer_store_event_hold, gobble_input):
5814 (record_asynch_buffer_change) [USABLE_SIGIO]:
5815 (store_user_signal_events):
5816 No need to mess with signal mask.
5817 (gobble_input): If blocking input and there are terminals, simply
5818 set pending_signals to 1 and return. All hooks changed to not
5819 worry about whether input is blocked.
5820 (process_pending_signals): Clear pending_signals before processing
5821 them, in case a signal comes in while we're processing.
5822 By convention callers now test pending_signals before calling us.
5823 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5824 New functions, to support changes to blockinput.h.
5825 (handle_input_available_signal): Now extern.
5826 (reinvoke_input_signal): Remove. All uses replaced by
5828 (quit_count): Now volatile, since a signal handler uses it.
5829 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5830 All callers changed. Block SIGINT only if not already blocked.
5831 Clear sigmask reliably, even if Fsignal returns, which it can.
5832 Omit unnecessary accesses to volatile var.
5833 (quit_throw_to_read_char): No need to restore sigmask.
5834 * keyboard.c (gobble_input, handle_user_signal):
5835 * process.c (wait_reading_process_output):
5836 Call signal-handling code rather than killing ourselves.
5837 * lisp.h: Include <float.h>, for...
5838 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5839 (pending_signals): Now volatile.
5840 (syms_of_data): Now const if IEEE floating point.
5841 (handle_input_available_signal) [USABLE_SIGIO]:
5842 (terminate_due_to_signal, record_child_status_change): New decls.
5843 * process.c (create_process): Avoid disaster if memory is exhausted
5844 while we're processing a vfork, by tightening the critical section
5846 (send_process_frame, process_sent_to, handle_pipe_signal)
5847 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5849 (send_process): No need for setjmp/longjmp any more, since the
5850 SIGPIPE stuff is now gone. Instead, report an error if errno
5852 (record_child_status_change): Now extern. PID and W are now args.
5853 Return void, not bool. All callers changed.
5854 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5855 Remove. All uses removed. This bug should be fixed now in a
5857 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5858 and record the child status change directly. This avoids the
5859 need to futz with the signal mask.
5860 (process_fatal_action): Move here from emacs.c.
5861 (emacs_sigaction_flags): New function, containing
5862 much of what used to be in emacs_sigaction_init.
5863 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5864 caught by emacs, to make races less likely.
5865 (deliver_process_signal): Rename from handle_on_main_thread.
5867 (BACKTRACE_LIMIT_MAX): Now at top level.
5868 (thread_backtrace_buffer, threadback_backtrace_pointers):
5870 (deliver_thread_signal, deliver_fatal_thread_signal):
5871 New functions, for more-accurate delivery of thread-specific signals.
5872 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5873 (deliver_arith_signal): Handle in this thread, not
5874 in the main thread, since it's triggered by this thread.
5875 (maybe_fatal_sig): New function.
5876 (init_signals): New arg DUMPING so that we can be more accurate
5877 about whether we're dumping. Caller changed.
5878 Treat thread-specific signals differently from process-general signals.
5879 Block all signals while handling fatal error; that's safer.
5880 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5882 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5883 Ignore SIGPIPE unless batch.
5884 (emacs_backtrace): Output backtrace for the appropriate thread,
5885 which is not necessarily the main thread.
5886 * syssignal.h: Include <stdbool.h>.
5887 (emacs_raise): New macro.
5888 * xterm.c (x_connection_signal): Remove; no longer needed
5889 now that we use sigaction.
5890 (x_connection_closed): No need to mess with sigmask now.
5891 (x_initialize): No need to reset SIGPIPE handler here, since
5892 init_signals does this for us now.
5894 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5896 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5897 background rect may be larger (Bug#12245).
5899 2012-09-23 Chong Yidong <cyd@gnu.org>
5901 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5903 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5905 * .gdbinit: Just stop at fatal_error_backtrace.
5906 See Stefan Monnier's request in
5907 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5908 Remove no-longer-used query of system type.
5910 2012-09-22 Chong Yidong <cyd@gnu.org>
5912 * search.c (Freplace_match): Doc fix (Bug#12325).
5914 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5916 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5917 (Fline_end_position): Doc fix.
5919 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5921 2012-09-22 Chong Yidong <cyd@gnu.org>
5923 * dispextern.h (struct image_type): Add new slot, storing a type
5924 initialization function.
5926 * image.c (define_image_type): Call the image initializer function
5927 if it is defined. Arguments and return value changed.
5928 (valid_image_p, make_image): Callers changed.
5929 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5930 (gif_type, imagemagick_type, svg_type, gs_type):
5931 Add initialization functions.
5932 (Finit_image_library): Call lookup_image_type.
5933 (CHECK_LIB_AVAILABLE): Macro deleted.
5934 (lookup_image_type): Call define_image_type here, rather than via
5935 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5936 (syms_of_image): Move define_image_type calls for xbm_type and
5937 pbm_type to lookup_image_type.
5939 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5941 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5942 'idle_timers' from here ...
5943 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5944 lists, to avoid infloops when the timer does something stupid,
5945 like reinvoke itself with the same or smaller time-out.
5948 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5950 * window.c (Fsplit_window_internal): Handle only Qt value of
5951 Vwindow_combination_limit separately.
5952 (Qtemp_buffer_resize): New symbol.
5953 (Vwindow_combination_limit): New default value.
5956 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5958 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5959 the new overlay string. (Bug#10159)
5961 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5963 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5964 or that fprintf is async-signal-safe. POSIX doesn't require
5967 2012-09-22 Chong Yidong <cyd@gnu.org>
5969 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5972 2012-09-22 Kenichi Handa <handa@gnu.org>
5974 * composite.c (composition_reseat_it): Handle the case that a
5975 grapheme cluster is not covered by a single font (Bug#12352).
5977 2012-09-21 Chong Yidong <cyd@gnu.org>
5979 * image.c (define_image_type): Avoid adding duplicate types to
5980 image_types (Bug#12463). Suggested by Jörg Walter.
5982 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5984 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5985 (print_load_command_name): Add case LC_DATA_IN_CODE.
5986 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5988 2012-09-21 Glenn Morris <rgm@gnu.org>
5990 * eval.c (Frun_hook_with_args_until_success)
5991 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5993 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5995 * fileio.c (Ffile_selinux_context): Only call freecon when
5996 lgetfilecon succeeded.
5997 (Fset_file_selinux_context): Likewise. (Bug#12444)
5999 2012-09-21 Eli Zaretskii <eliz@gnu.org>
6001 * xdisp.c (try_window_reusing_current_matrix): Under bidi
6002 reordering, locate the cursor by calling set_cursor_from_row; if
6003 that fails, clear the desired glyph matrix before returning a
6004 failure indication to the caller. Fixes leaving garbled display
6005 when fast scrolling with a down-key. (Bug#12403)
6006 (compute_stop_pos_backwards): Fix a typo that caused crashes while
6007 scrolling through multibyte text.
6009 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
6011 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
6012 calling mark_vectorlike since that's the one that marks the window.
6013 (mark_discard_killed_buffers): Mark the final cdr.
6014 * window.h (struct window): Move prev/next_buffers to the
6015 non-standard fields.
6016 * window.c (make_window): Initialize prev/next_buffers manually.
6018 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
6020 Omit unused arg EXPECTED from socket hooks.
6021 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
6022 * nsterm.m (ns_term_init):
6023 * termhooks.h (struct terminal.read_socket_hook):
6024 * w32inevt.c (w32_console_read_socket):
6025 * w32term.c (w32_read_socket):
6026 * xterm.c (XTread_socket):
6027 Omit unused arg EXPECTED. All callers changed.
6028 (store_user_signal_events): Return void, not int, since callers no
6029 longer care about the return value. All uses changed.
6031 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
6033 * w32gui.h (XParseGeometry): Do not declare.
6035 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
6037 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
6038 Ignore 'expected'. See Eli Zaretskii in
6039 <http://bugs.gnu.org/12471#8> (last line).
6041 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
6042 (XParseGeometry): Now static. Substitute extremal values for
6043 values that are out of range.
6045 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
6047 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
6049 * nsfns.m (XParseGeometry): Remove.
6050 (Fx_create_frame): Call x_set_offset to correctly interpret
6051 top_pos in geometry.
6053 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
6054 (Fx_parse_geometry): If there is a space in string, call
6055 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
6057 2012-09-17 Eli Zaretskii <eliz@gnu.org>
6059 * search.c (scan_buffer): Use character positions in calls to
6060 region_cache_forward and region_cache_backward, not byte
6061 positions. (Bug#12196)
6063 * w32term.c (w32_read_socket): Set pending_signals to 1, like
6064 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
6066 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
6067 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
6068 emacs_blocked_malloc, now deleted.
6070 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
6072 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
6073 The workaround was for improving performance on Solaris 2.4, but
6074 is getting in the way now. Emacs will still work if someone is
6075 still running Solaris 2.4 in a museum somewhere; Sun dropped
6076 support for Solaris 2.4 in 2003.
6077 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
6078 * process.c (create_process) [HAVE_WORKING_VFORK]:
6079 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
6080 since Emacs no longer uses vfork on that platform.
6082 2012-09-17 Glenn Morris <rgm@gnu.org>
6084 * emacs.c: Use COPYRIGHT.
6086 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
6088 Remove configure's --without-sync-input option (Bug#12450).
6089 When auditing signal-handling in preparation for cleaning it up,
6090 I found that SYNC_INPUT has race conditions and would be a real
6091 pain to fix. Since it's an undocumented and deprecated
6092 configure-time option, now seems like a good time to remove it.
6093 Also see <http://bugs.gnu.org/11080#16>.
6094 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
6095 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
6096 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6097 (malloc_hysteresis):
6098 (check_depth) [XMALLOC_OVERRUN_CHECK]:
6099 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
6100 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
6101 (dont_register_blocks, bytes_used_when_reconsidered)
6102 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
6103 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
6104 [!SYSTEM_MALLOC && !SYNC_INPUT]:
6105 Remove. All uses removed.
6106 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
6107 implementation, one that depends on whether the new macro
6108 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
6110 * atimer.c (run_timers, handle_alarm_signal):
6111 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
6112 (handle_async_input, process_pending_signals)
6113 (handle_input_available_signal, init_keyboard):
6114 * nsterm.m (ns_read_socket):
6115 * process.c (wait_reading_process_output):
6116 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
6117 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
6119 * xterm.c (XTread_socket):
6121 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
6122 * eval.c (handling_signal): Remove. All uses removed.
6123 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
6124 All uses replaced with the SYNC_INPUT version.
6125 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
6127 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6130 * font.c (Ffont_shape_gstring): Remove unused local.
6132 2012-09-16 Glenn Morris <rgm@gnu.org>
6134 * Makefile.in (clean): No longer run nextstep's clean.
6136 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
6138 (ns-app): Move here from ns.mk, and simplify.
6139 (clean): Simplify nextstep entry.
6140 * ns.mk: Remove file.
6142 2012-09-17 Kenichi Handa <handa@gnu.org>
6144 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
6145 not covert the last few charactes.
6147 2012-09-16 Kenichi Handa <handa@gnu.org>
6149 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
6150 here, but just check the validity of glyphs in the glyph-string.
6152 2012-09-16 Martin Rudalics <rudalics@gmx.at>
6154 * window.c (Fwindow_parameter, Fset_window_parameter):
6155 Accept any window as argument (Bug#12452).
6157 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
6159 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
6160 to ns_term_init to avoid memory leak.
6162 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
6163 explicit retain/release.
6164 (ns_term_init): Only allow one display. Initialize outerpool and
6167 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6169 Port _setjmp fix to POSIXish hosts as well as Microsoft.
6170 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
6171 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
6172 the Microsoft problem in a different way, by altering ../nt/config.nt.
6174 2012-09-15 Eli Zaretskii <eliz@gnu.org>
6189 * w16select.c: Remove inclusion of setjmp.h, as it is now included
6190 by lisp.h. This completes removal of setjmp.h inclusion
6191 erroneously announced in the previous commit. (Bug#12446)
6193 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
6196 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
6197 not defined as a macro. The latter happens on MS-Windows.
6200 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6202 Port better to POSIX hosts lacking _setjmp (Bug#12446).
6203 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
6204 Some instances of '#include <setjmp.h>' removed, if the
6205 only reason for the instance was because "lisp.h" was included.
6206 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
6207 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
6208 and _longjmp with the new symbols. Emacs already uses _setjmp if
6209 available, so this change affects only POSIXish hosts that have
6210 sigsetjmp but not _setjmp, such as some versions of Solaris and
6211 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
6212 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
6213 (png_load_body) [HAVE_PNG]:
6214 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
6215 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
6216 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
6217 since PNG requires jmp_buf. This is the only exception to the
6218 general rule that we now use sys_setjmp and sys_longjmp.
6219 This exception is OK since this code does not change the signal
6220 mask or longjmp out of a signal handler.
6222 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
6224 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6225 Include "syssignal.h", for 'main_thread'.
6227 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
6229 Avoid out-of-range marker position (Bug#12426).
6230 * insdel.c (replace_range, replace_range_2):
6231 Adjust markers before overlays, as suggested by comments.
6232 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
6233 Remove redundant check before calling offset_intervals.
6235 2012-09-14 Martin Rudalics <rudalics@gmx.at>
6237 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
6238 current buffer (Bug#12387).
6240 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
6242 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
6244 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6246 Use a more backwards-compatible timer format (Bug#12430).
6247 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
6248 vector element, not from the 4th, since PSECS is now at the end.
6249 (Fcurrent_idle_time): Doc fix.
6251 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
6253 Function to mark objects and remove killed buffers at once.
6254 * alloc.c (discard_killed_buffers): Rename to ...
6255 (mark_discard_killed buffers) ... new name. Add marking
6256 of remaining objects. Fix comment. Adjust users.
6257 (mark_object): Do not touch frame buffer lists here.
6258 * frame.c (delete_frame): Reset frame buffer lists here.
6260 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6262 Better workaround for GNOME bug when --enable-gcc-warnings.
6263 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
6264 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
6265 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
6267 Simplify SIGIO usage (Bug#12408).
6268 The code that dealt with SIGIO was crufty and confusing, e.g., it
6269 played tricks like "#undef SIGIO" but these tricks were not used
6270 consistently. Simplify mostly by not #undeffing standard symbols,
6271 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
6272 or not as we please) rather than "defined SIGIO" (standard symbol
6273 that we probably shouldn't #undef).
6274 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
6275 Modules that need it can include it.
6276 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
6277 * dispextern.h (ignore_sigio): New decl.
6278 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
6279 unconditionally, since it's now a no-op if !USABLE_SIGIO.
6280 * emacs.c (shut_down_emacs):
6281 * keyboard.c (kbd_buffer_store_event_hold):
6282 Use ignore_sigio rather than invoking 'signal' directly.
6283 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
6285 (FIONREAD, SIGIO): Do not #undef.
6286 (tty_read_avail_input): Use #error rather than a syntax error.
6287 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
6288 for I_PIPE, used by SETUP_SLAVE_PTY.
6289 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
6290 * sysdep.c (croak): Remove; no longer needed. This bit of
6291 temporary code, with Fred N. Fish's comment that it's temporary,
6292 has been in Emacs since at least 1992!
6293 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
6294 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
6295 * syssignal.h (croak): Remove decl.
6296 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
6297 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
6298 now that we're termios-only.
6299 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
6300 * term.c (dissociate_if_controlling_tty): Use #error rather than
6303 Work around GCC and GNOME bugs when --enable-gcc-warnings.
6304 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
6305 to work around GNOME bug 683906.
6306 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
6307 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
6308 This works around GCC bug 54561.
6310 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6312 More fixes for 'volatile' and setjmp/longjmp.
6313 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
6314 * image.c (struct png_load_context) [HAVE_PNG]: New type.
6315 (png_load_body) [HAVE_PNG]:
6316 (jpeg_load_body) [HAVE_JPEG]:
6317 New function, with most of the old parent function's body.
6318 (png_load) [HAVE_PNG]:
6319 (jpeg_load) [HAVE_JPEG]:
6320 Invoke the new function, to avoid longjmp munging our locals.
6321 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
6322 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
6323 longjmp is passed 2, as the C standard doesn't guarantee this.
6324 Instead, store the failure code into mgr->failure_code.
6326 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6328 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
6329 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
6330 (syms_of_keyboard): Remove support for unread-command-char.
6332 2012-09-12 Eli Zaretskii <eliz@gnu.org>
6334 * w32proc.c (sys_kill): If PID is our process ID and the signal is
6335 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
6336 violation. (Bug#12426)
6338 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6340 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
6342 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6344 * eval.c: Add `inhibit-debugger'.
6345 (Qinhibit_debugger): New symbol.
6346 (call_debugger): Bind it instead of Qdebug_on_error.
6347 (maybe_call_debugger): Test Vinhibit_debugger.
6348 (syms_of_eval): Define inhibit-debugger.
6349 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6350 (syms_of_xdisp): Remove inhibit-debug-on-message.
6352 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6354 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6355 If a nonvolatile local variable is written before a _longjmp to
6356 the frame containing the variable, and is read after the _longjmp,
6357 the value read is indeterminate. Some local variables of type
6358 'struct handler' and 'struct catchtag' are used in this way, so
6359 mark each of their slots as volatile if the slot can be set before
6360 _longjmp and read afterwards.
6361 * lisp.h (struct handler): var and chosen_clause are now volatile.
6362 (struct catchtag): val, next, and pdlcount are now volatile.
6364 * bidi.c (bidi_push_it, bidi_pop_it):
6365 * fns.c (copy_hash_table):
6366 * image.c (define_image_type):
6367 * keyboard.c (kbd_buffer_store_event_hold):
6368 * process.c (Fprocess_send_eof):
6369 * xfaces.c (x_create_gc) [HAVE_NS]:
6370 * xgselect.c (xg_select):
6371 Prefer assignment to memcpy when either will do.
6373 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6374 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6375 time an item is removed. No need to mark this function 'inline';
6376 the compiler knows better than we do.
6378 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6380 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6381 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6382 to change_frame_size (Bug#12388).
6383 (windowDidResize:): Pass YES to updateFrameSize.
6385 * nsterm.h: Add delay parameter to updateFrameSize.
6387 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6389 Discard killed buffers from deleted window and frame objects.
6390 This reduces an amount of references to killed buffers and
6391 helps GC to reclaim them faster.
6392 * alloc.c (discard_killed_buffers): New function.
6393 (mark_object): Use it for deleted windows and frames.
6394 (mark_object): If symbol's value is set up for a killed buffer
6395 or deleted frame, restore its global binding.
6396 * data.c (swap_in_global_binding): Add GC notice.
6397 (swap_in_symval_forwarding): Use convenient set_blv_where.
6398 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6399 * window.h: ... to here.
6401 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6403 Convenient macro to check whether the buffer is live.
6404 * buffer.h (BUFFER_LIVE_P): New macro.
6405 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6406 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6408 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6410 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6411 composition cases (Bug#12364).
6413 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6414 overhang of succeeding glyphs overlapping box cursor.
6416 * w32term.c (x_draw_glyph_string): Likewise.
6418 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6420 Simplify, document, and port floating-point (Bug#12381).
6421 The porting part of this patch fixes bugs on non-IEEE platforms
6422 with frexp, ldexp, logb.
6423 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6425 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6426 support, by removing commented-out code and briefly listing the
6427 C89 functions excluded. The commented-out stuff was confusing
6428 maintenance, e.g., we thought we needed cbrt but it was commented out.
6429 (logb): Remove decl; no longer needed.
6430 (isfinite): New macro, if not already supplied.
6431 (isnan): Don't replace any existing macro.
6432 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6433 are present on all C89 platforms.
6434 (Ffrexp): Do not special-case zero, as frexp does the right thing
6436 (Flogb): Do not use logb, as it doesn't have the desired meaning
6437 on hosts that use non-base-2 floating point. Instead, stick with
6438 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6439 frexp, to avoid getting an unspecified result.
6441 * xdisp.c (Qinhibit_debug_on_message): Now static.
6443 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6445 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6446 NSBezierPath (Bug#12131).
6448 2012-09-10 Chong Yidong <cyd@gnu.org>
6450 * fns.c (Fdelq, Fdelete): Doc fix.
6452 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6454 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6455 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6457 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6459 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6460 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6463 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6465 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6466 left fringe if the window has a left margin. This avoids leaving
6467 traces of the cursor because its leftmost pixel is not drawn over.
6469 * dispnew.c (update_window_line): When the left margin area of a
6470 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6471 that screen line. (Bug#12277)
6473 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6475 Assume C89 or later for math functions (Bug#12381).
6476 This simplifies the code, and makes it a bit smaller and faster,
6477 and (most important) makes it easier to clean up signal handling
6478 since we can stop worring about floating-point exceptions in
6479 library code. That was a problem before C89, but the problem
6480 went away many years ago on all practical Emacs targets.
6481 * data.c, image.c, lread.c, print.c:
6482 Don't include <math.h>; no longer needed.
6483 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6484 might be autoconfigured, as that never happens.
6486 * doprnt.c (DBL_MAX_10_EXP):
6487 * print.c (DBL_DIG):
6488 Remove. C89 or later always defines these.
6489 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6490 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6491 (arith_error, domain_error, domain_error2):
6492 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6493 no longer needed -- we simply return what C returns. All uses removed.
6494 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6496 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6497 Remove. All uses expanded, as these macros are no longer used
6498 more than once and are now more trouble than they're worth.
6499 (Ftan): Use tan, not sin / cos.
6500 (Flogb): Assume C89 frexp.
6501 (fmod_float): Assume C89 fmod.
6502 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6503 (init_floatfns): Remove. All uses removed.
6505 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6507 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6508 compositeToPoint for OSX < 10.6 (Bug#12390).
6510 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6512 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6513 This produces more-accurate results.
6515 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6517 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6518 changes (Bug#12088).
6520 2012-09-08 Chong Yidong <cyd@gnu.org>
6522 * syntax.c (Fstring_to_syntax): Doc fix.
6524 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6526 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6527 in the internal border.
6528 (x_set_window_size): Remove static variables and their usage.
6529 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6530 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6531 Remove fringe/internal border adjustment (Bug#11052).
6532 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6533 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6534 (ns_fix_rect_ibw): Remove.
6535 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6536 (ns_dumpglyphs_box_or_relief): Ditto.
6537 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6539 (ns_dumpglyphs_image): Ditto.
6540 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6542 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6543 their usage. Add fringe_extended_p and its use as in other terms.
6544 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6545 scroll bar was removed.
6546 (updateFrameSize): New function.
6547 (windowDidResize): Move code to updateFrameSize and call it.
6549 * nsterm.h (EmacsView): Add updateFrameSize.
6551 2012-09-07 Chong Yidong <cyd@gnu.org>
6553 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6555 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6557 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6559 More signal-handler cleanup (Bug#12327).
6560 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6561 Problem introduced when merging patches. Noted by Eli Zaretskii in
6562 <http://bugs.gnu.org/12327#67>.
6563 * floatfns.c: Comment fix.
6564 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6565 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6566 and anyway the declaration is harmless even if SIGDANGER is not defined.
6567 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6568 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6569 source files not surprisingly expected syssignal.h to define, or
6570 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6571 Include <sys/ioctl.h>, for FIONREAD.
6572 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6573 This eliminates a problem whereby other files mysteriously had
6574 to include "syssignal.h" before including "systty.h" if they
6575 wanted to use "#ifdef SIGIO".
6577 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6579 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6581 * w32.c (sigemptyset): Empty the set.
6582 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6584 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6586 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6588 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6589 (mark_object): Likewise for frame objects.
6591 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6593 * syssignal.h (handle_on_main_thread): Always declare,
6594 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6595 This ports to platforms without HAVE_PTHREAD.
6597 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6599 Signal-handler cleanup (Bug#12327).
6600 Emacs's signal handlers were written in the old 4.2BSD style with
6601 sigblock and sigmask and so forth, and this led to some
6602 inefficiencies and confusion. Rewrite these to use
6603 pthread_sigmask etc. without copying signal sets around. Also,
6604 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6605 'signal', and instead use functions that do not attempt to take
6606 over the system name space. This patch causes Emacs's text
6607 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6608 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6609 Do not include <signal.h> or "syssignal.h", as these
6610 modules do not use signals.
6611 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6612 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6613 Do not include <signal.h>, as "syssignal.h" does that for us now.
6614 * atimer.c (sigmask_atimers): New function.
6615 (block_atimers, unblock_atimers): New functions,
6616 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6618 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6619 no longer needed here.
6620 * emacs.c (main): Inspect existing signal handler with sigaction,
6621 so that there's no need to block and unblock SIGHUP.
6622 * sysdep.c (struct save_signal): New member 'action', replacing
6623 old member 'handler'.
6624 (save_signal_handlers, restore_signal_handlers):
6625 Use sigaction instead of 'signal' to save and restore.
6626 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6627 New function. All users of 'signal' modified to use set_sighandler
6628 if they're writeonly, and to use sys_signal if they're read+write.
6629 (emacs_sigaction_init, forwarded_signal): New functions.
6630 (sys_signal): Remove. All uses replaced by calls to sigaction
6631 and emacs_sigaction_init, or by direct calls to 'signal'.
6632 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6633 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6634 all uses replaced by pthread_sigmask etc. calls.
6635 * syssignal.h: Include <signal.h>.
6636 (emacs_sigaction_init, forwarded_signal): New decls.
6637 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6638 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6639 (sigmask, sys_sigmask): Remove; no longer needed.
6640 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6641 (sigblock, sigunblock, sigfree):
6642 (sigsetmask) [!defined sigsetmask]:
6643 Remove. All uses replaced by pthread_sigmask.
6644 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6645 no longer need to be replaced, and its typical old uses
6646 are now done via emacs_sigaction_init and sigaction.
6647 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6648 (sys_sigdel): Remove; unused.
6649 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6651 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6653 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6654 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6656 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6658 Explicitly mark buffer_defaults and buffer_local_symbols.
6659 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6660 mark_local_symbols here.
6661 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6662 since special buffers aren't marked here any more.
6663 (allocate_buffer): Chain new buffer with all_buffers here...
6664 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6666 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6667 (syms_of_buffer): Remove staticpro of the above.
6668 (init_buffer_once): Set names for buffer_defaults and
6669 buffer_local_symbols.
6671 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6673 Use bool for booleans in font-related modules.
6674 * font.c (font_intern_prop, font_style_to_value)
6675 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6676 (generate_otf_features, font_check_otf_features, font_check_otf)
6677 (font_match_p, font_list_entities, font_at):
6678 * fontset.c (fontset_id_valid_p, reorder_font_vector
6679 (fontset_find_font, Fset_fontset_font)
6680 (face_suitable_for_char_p) [0]:
6681 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6682 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6683 (m17n_flt_initialized, ftfont_shape_by_flt):
6684 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6685 * nsfont.m (nsfont_draw):
6686 * w32font.c (w32font_draw):
6687 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6688 Use bool for booleans.
6689 * font.h: Adjust to above API changes.
6690 (struct font, struct font_driver, struct font_driver_list):
6691 Use bool for booleans.
6692 (struct font): Remove useless member encoding_type.
6694 * fontset.c, xftfont.c: Omit unnecessary static decls.
6696 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6698 * alloc.c (mark_object): Revert window marking code
6699 since it's unsafe for the Fset_window_configuration.
6701 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6703 Fix race conditions with signal handlers and errno (Bug#12327).
6704 Be more systematic about preserving errno whenever a signal
6705 handler returns, even if it's not in the main thread. Do this by
6706 renaming signal handlers to distinguish between signal delivery
6707 and signal handling. All uses changed.
6708 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6709 * data.c (deliver_arith_signal): Rename from arith_error.
6710 * dispnew.c (deliver_window_change_signal): Rename from
6711 window_change_signal.
6712 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6713 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6714 * keyboard.c (deliver_input_available_signal): Rename from
6715 input_available_signal.
6716 (deliver_user_signal): Rename from handle_user_signal.
6717 (deliver_interrupt_signal): Rename from interrupt_signal.
6718 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6719 (deliver_child_signal): Rename from sigchld_handler.
6720 * atimer.c (handle_alarm_signal):
6721 * data.c (handle_arith_signal):
6722 * dispnew.c (handle_window_change_signal):
6723 * emacs.c (handle_fatal_signal, handle_danger_signal):
6724 * keyboard.c (handle_input_available_signal):
6725 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6726 * process.c (handle_pipe_signal, handle_child_signal):
6727 New functions, with the actual signal-handling code taken from the
6728 original respective signal handlers, sans the sporadic attempts to
6729 preserve errno, since that's now done by handle_on_main_thread.
6730 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6731 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6732 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6734 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6735 Move initialization of main_thread to sysdep.c's init_signals.
6736 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6737 our usage, and simplifies the mainline code.
6738 (record_child_status_change): New static function, as a helper
6739 for handle_child_signal, and with most of the old child handler's
6741 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6742 (handle_child_signal): Use the above.
6743 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6744 Moved here from emacs.c.
6745 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6746 code moved here from emacs.c's main function.
6747 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6748 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6749 This lets callers save and restore errno properly.
6751 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6753 Remove redundant or unused things here and there.
6754 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6755 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6756 * editfns.c (Fcompare_buffer_substrings): Likewise.
6757 * frame.h (struct terminal, struct font_driver_list):
6758 Remove redundant declarations.
6759 * window.h (Qleft, Qright): Likewise.
6761 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6763 Do not mark objects from deleted buffers, windows and frames.
6764 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6765 (mark_object): Likewise for windows and frames.
6767 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6769 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6770 buffer_defaults and buffer_local_symbols as valid objects.
6771 Return special value to denote them.
6773 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6775 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6776 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6777 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6778 (file_name_absolute_p, Fsubstitute_in_file_name):
6779 (check_executable, check_writable, Ffile_accessible_directory_p)
6780 (Fset_file_selinux_context, Fdefault_file_modes)
6781 (Finsert_file_contents, choose_write_coding_system)
6782 (Fwrite_region, build_annotations, a_write, e_write)
6784 * filelock.c (boot_time_initialized, get_boot_time)
6785 (get_boot_time_1, lock_file_1, within_one_second):
6786 * floatfns.c (in_float):
6787 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6788 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6789 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6790 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6791 * window.c (compare_window_configurations):
6792 Use bool for booleans.
6793 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6794 (Fdefault_file_modes): Now mode_t, not int, for modes.
6795 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6796 (internal_delete_file): Now returns void, not a (boolean) int,
6797 since nobody was looking at the return value.
6798 * lisp.h, window.h: Adjust to above API changes.
6800 * xdisp.c (set_message): Simplify and reindent last change.
6802 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6804 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6806 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6808 * eval.c (call_debugger): Make the function non-static so that we
6809 can call it from set_message.
6811 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6812 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6814 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6816 Give more-useful info on a fatal error (Bug#12328).
6817 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6818 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6819 of doing the work ourselves.
6820 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6821 do most of the work.
6822 (fatal_error_backtrace): New function, taken from the guts
6823 of the old fatal_error_signal, but with a new option to output
6825 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6826 info about the signal than just its number.
6827 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6828 * sysdep.c: Include <execinfo.h>
6829 (emacs_backtrace): New function, taken partly from the previous
6830 code of the 'die' function.
6831 (emacs_abort): Call fatal_error_backtrace rather than abort.
6833 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6835 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6836 eager (load-time) macro-expansion.
6837 * lisp.mk (lisp): Add macroexp.
6839 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6841 Simplify redefinition of 'abort' (Bug#12316).
6842 Do not try to redefine the 'abort' function. Instead, redo
6843 the code so that it calls 'emacs_abort' rather than 'abort'.
6844 This removes the need for the NO_ABORT configure-time macro
6845 and makes it easier to change the abort code to do a backtrace.
6846 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6847 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6848 Remove; sysdep.c's emacs_abort now takes its place.
6849 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6850 'abort' changed to use 'emacs_abort'.
6851 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6852 (abort) [!defined abort]: Rename to ...
6853 (emacs_abort): ... new name.
6854 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6855 the place of the old 'abort' in emacs.c.
6856 * w32.c, w32fns.c (abort): Do not #undef.
6857 * w32.c (emacs_abort): Rename from w32_abort.
6859 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6861 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6862 offsets[j].dv, since the y axis of the screen coordinates points
6863 down, while the y axis of the font definition coordinates points
6864 up. This fixes display of Arabic diacritics such as KASRA and
6865 KASRATAN. (Bug#11860)
6867 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6869 Be more systematic about _setjmp vs setjmp.
6870 * alloc.c (test_setjmp, mark_stack):
6871 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
6872 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
6873 (png_load, my_error_exit, jpeg_load):
6874 * process.c (send_process_trap, send_process):
6875 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6876 The underscored versions are up to 30x faster on some hosts.
6877 Formerly, the code used setjmp+longjmp sometimes and
6878 _setjmp+_longjmp at other times, with no particular reason to
6879 prefer setjmp+longjmp.
6881 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
6883 Fix minor problem found by static checking.
6884 * buffer.c (Fdelete_all_overlays): Return nil.

6910 EXCLUDE_SUBRS_P. All callers changed.
6911 * dispextern.h, lisp.h: Reflect above API changes.
6912 * firstfile.c (dummy): Use the address of 'main', whose signature
6913 won't change, instead of the address of 'initialize', whose
6914 signature just changed from int to bool.
6915 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
6916 * msdos.c (fatal_error_in_progress): ... from here.
6917 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6919 (redisplay_internal, unwind_redisplay): Simply clear
6920 REDISPLAYING_P when unwinding, instead of saving its previous,
6921 always-false value and then restoring it.
6923 Clean up some extern decls.
6924 Mostly, this hoists extern decls out of .c files and into .h files.
6925 That way, we're more likely to catch errors if the interfaces change.
6926 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6927 declare xg_mark_data.
6928 * dispextern.h (x_frame_parm_handlers):
6930 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

6946 * xfont.c (x_clear_errors):
6947 * xterm.c (x_frame_parm_handlers):
6948 Remove now-redundant extern decls.
6949 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
6950 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
6952 * xfaces.c: Remove unnecessary static decls.
6953 * xterm.c (updating_frame): Remove decl of nonexistent object.
6955 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
6956 when building globals.h, as the objects that are not built on
6957 this host are not needed to compile C files on this host.
6959 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
6961 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

6989 * keyboard.c (decode_timer):
6990 Use bool for boolean.
6991 * intervals.h, lisp.h, systime.h: Reflect above API changes.

7009 2012-09-01 Eli Zaretskii <eliz@gnu.org>
7011 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
7012 more than one grapheme cluster passed to the shaper: compute the
7013 offset adjustment values separately for each cluster. (Bug#11860)
7015 * image.c: Restore mistakenly removed inclusion of w32.h. Without
7016 it, GCC doesn't see prototypes of w32_delayed_load, and complains
7017 about implicit conversions from integer to pointer.
7019 2012-09-01 Daniel Colascione <dancol@dancol.org>
7021 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
7022 system used too early.
7024 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
7026 Better seed support for (random).

7075 window system declarations.
7077 * frame.h: Move common functions here: set_frame_menubar,
7078 x_set_window_size, x_sync, x_get_focus_frame,
7079 x_set_mouse_position, x_set_mouse_pixel_position,
7080 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

7107 * lisp.h (mark_ttys): Remove prototype.
7108 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call

7110 the frames which are reachable from Vframe_list.
7111 * term.c (mark_ttys): Remove.
7112 (init_tty): Safely initialize 'top_frame' slot with Qnil.

7141 * lread.c (init_lread): For out-of-tree builds, only add the
7142 source directory's site-lisp dir to the load-path if it exists,
7143 consistent with in-tree builds. (Bug#12302)

7164 Handle click on close button as quit.
7166 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
7167 Add window_closed and button_values. Add void as return value for
7168 add(Button|String|Split). addButton takes int instead of Lisp_Object.
7169 Add process_dialog as new member.
7171 2012-08-28 Eli Zaretskii <eliz@gnu.org>
7173 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

7303 (code_convert_string, code_convert_string_norecord)
7304 (Fset_coding_system_priority):
7305 * fileio.c (Finsert_file_contents):
7306 Use bool for booleans.
7307 * coding.h, lisp.h: Reflect above API changes.
7308 * coding.c: Remove unnecessary static function decls.
7309 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
7310 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
7311 not a boolean 'int', since callers never look at the return value.
7312 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
7313 * coding.h (decoding_buffer_size, encoding_buffer_size)
7314 (emacs_mule_string_char): Remove unused extern decls.
7315 (struct iso_2022_spec, struct coding_system):
7316 Use 'unsigned int : 1' for boolean fields, since there's more than one.
7317 (struct emacs_mule_spec): Remove unused field 'full_support'.
7318 All initializations removed.
7319 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
7321 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7323 Fix spare memory change (Bug#12286).
7324 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
7325 (valid_lisp_object_p): Likewise.
7327 2012-08-27 Martin Rudalics <rudalics@gmx.at>
7329 * window.c (Fset_window_configuration): Record any window's old
7330 buffer if it's replaced (see Bug#8789). If the new current
7331 buffer doesn't appear in the selected window, go to its old
7334 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7336 Special MEM_TYPE_SPARE to denote reserved memory.
7337 * alloc.c (enum mem_type): New memory type.
7338 (refill_memory_reserve): Use new type for spare memory.
7339 This prevents live_cons_p and live_string_p from incorrect
7340 detection of uninitialized objects from spare memory as live.
7342 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
7345 * Makefile.in (.PHONY): versioclean -> versionclean.
7347 Remove unused external symbols.
7348 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
7349 * window.c (Qwindow_valid_p, decode_valid_window):
7350 Now static, not extern.
7351 * data.c (Qinterval): Remove; unused.
7352 (syms_of_data): Do not define 'interval'.
7353 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
7354 * window.h (decode_valid_window):
7357 * character.c, charset.c, chartab.c: Use bool for booleans.
7358 * character.c (lisp_string_width, string_count_byte8)
7359 (string_escape_byte8):
7360 * charset.c (charset_map_loaded, load_charset_map, read_hex):
7361 (load_charset_map_from_file, map_charset_chars)
7362 (Fdefine_charset_internal, define_charset_internal)
7363 (Fdeclare_equiv_charset, find_charsets_in_text)
7364 (Ffind_charset_region, char_charset, Fiso_charset):

7366 (sub_char_table_set, sub_char_table_set_range)
7367 (char_table_set_range, optimize_sub_char_table)
7368 (map_sub_char_table):
7369 Use bool for boolean.
7370 * character.c (str_to_unibyte): Omit last boolean argument; it was
7371 always 0. All callers changed.
7372 * character.h, charset.h: Adjust to match previous changes.
7373 * character.h (char_printable_p): Remove decl of nonexistent function.
7374 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
7375 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
7376 are all boolean, so make them single-bit bitfields.
7378 * lisp.h (ASET): Remove attempt to detect side effects.
7379 It was meant to be temporary and it often doesn't work,
7380 because when IDX has side effects the behavior of IDX==IDX
7381 is undefined. See Stefan Monnier in
7382 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
7384 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
7386 * lisp.h (functionp): New function (extracted from Ffunctionp).
7387 (FUNCTIONP): Use it.
7388 * eval.c (Ffunctionp): Use it.
7390 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7392 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7393 as that's faster and simpler than static storage. Don't bother
7394 with the g_main_context_query overhead if g_main_context_pending
7395 says no events are pending.
7396 (gfds, gfds_size): Remove these static vars.
7397 (xgselect_initialize): Remove; no longer needed.
7398 All uses and decls removed.
7400 * emacs.c (fatal_error_signal_hook): Remove.
7401 All uses removed. This leftover from old code was always 0.
7403 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
7404 * casefiddle.c (casify_object, casify_region):
7405 * casetab.c (set_case_table):
7406 * category.c, category.h (word_boundary_p):
7407 * category.h (CHAR_HAS_CATEGORY):
7408 Use bool for booleans, instead of int.
7410 2012-08-25 Eli Zaretskii <eliz@gnu.org>
7412 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
7414 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7416 On assertion failure, print backtrace if available.
7417 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
7418 (die) [ENABLE_CHECKING]: Print a backtrace if available.
7419 * Makefile.in (LIB_EXECINFO): New macro.
7422 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
7423 * bytecode.c (exec_byte_code):
7424 * callint.c (check_mark, Fcall_interactively):
7425 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
7426 (getenv_internal, sync_process_alive, call_process_exited):
7427 * lisp.h (USE_SAFE_ALLOCA):
7428 Use bool for booleans, instead of int.
7429 * lisp.h, process.h: Adjust prototypes to match above changes.
7430 * callint.c (Fcall_interactively): Don't assume the mark's
7431 offset fits in 'int'.
7433 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7435 * buffer.c, buffer.h: Use bool for boolean.
7436 * buffer.c (reset_buffer_local_variables)
7437 (buffer_lisp_local_variables, Fset_buffer_modified_p)
7438 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
7439 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
7440 (overlay_touches_p, overlay_strings, Foverlay_put)
7441 (report_overlay_modification, call_overlay_mod_hooks):
7442 (mmap_enlarge, mmap_set_vars):
7443 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7444 Use bool for booleans, instead of int.
7445 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7446 since the 1-or-0 return value is always ignored anyway.
7447 (mmap_initialized_p):
7448 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7449 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7451 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7453 * bidi.c: Use bool for boolean.
7454 This is a bit more readable, and makes the text segment of bidi.o
7455 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7456 Presumably it's faster too.
7457 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
7459 (bidi_cache_find_level_change, bidi_cache_iterator_state)
7460 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
7461 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
7462 (bidi_explicit_dir_char, bidi_level_of_next_char)
7463 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7464 Use bool for booleans, instead of int.
7465 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7466 (bidi_unshelve_cache): Adjust decls to match code.
7468 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7470 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7473 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7475 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7476 * atimer.h: Include <stdbool.h>.
7478 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7480 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7481 compile time tests instead of run time tests on systems that do
7483 (FRAME_MAC_P): Remove leftover from deleted code.
7484 * frame.c (syms_of_frame): Remove leftover from deleted code.
7486 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
7488 * nsterm.m (insertText:): Don't clear modifiers if code is space.
7490 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7492 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7493 Otherwise, the compiler complains about (A?B:C) where B is void
7494 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7495 (fontset_add): Return void, for FONTSET_ADD.
7497 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7499 * alloc.c: Use bool for booleans.
7500 (gc_in_progress, abort_on_gc)
7501 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7502 (dont_register_blocks) [GC_MALLOC_CHECK]:
7503 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
7504 (check_string_bytes, make_specified_string, memory_full)
7505 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
7506 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7507 (mark_stack, valid_pointer_p, make_pure_string)
7508 (Fgarbage_collect, survives_gc_p, gc_sweep):
7509 Use bool for booleans, instead of int.
7510 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7511 Remove unused local.
7512 * alloc.c (PURE_POINTER_P):
7513 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7514 * editfns.c (Fformat):
7515 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7517 * fns.c (sweep_weak_table):
7518 * lisp.h (suppress_checking, push_message, survives_gc_p)
7519 (make_pure_string, gc_in_progress, abort_on_gc):
7520 * lread.c (readchar, read1):
7521 * print.c (Fprin1_to_string):
7522 * xdisp.c (push_message):
7523 Use bool for booleans affected directly or indirectly by
7526 Make recently-introduced setters macros.
7527 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7528 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7529 (set_fontset_default, set_fontset_fallback): Rename from their
7530 upper-case counterparts, and make them functions rather than macros.
7531 This is more consistent with the other recently-introduced setters.
7532 These don't need to be inline, since they're local.
7534 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7536 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7537 the loop (Bug#12247).
7539 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7541 * lisp.h (vcopy): Use memcpy rather than our own loop.
7542 This fixes a performance regression introduced by the recent
7543 addition of vcopy. This means 'vcopy' will need to be modified
7544 for a copying collector, but that's OK. Also, tighten the
7545 checking in the assertion.
7547 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7549 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7550 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7551 non-base glyph for the width of the base character, according to
7552 what x_draw_composite_glyph_string_foreground expects.
7553 Generate WADJUST value according to composition_gstring_width's
7554 expectations, to produce correct width of the composed character.
7555 Reverse the sign of the DU offset produced by ScriptPlace.
7557 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7559 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7561 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7563 Avoid direct writes to contents member of struct Lisp_Vector.
7564 * lisp.h (vcopy): New function to copy data into vector.
7565 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7566 * fns.c (Ffillarray): Use ASET.
7567 * keyboard.c (timer_check_2): Use AREF and ASET.
7568 (append_tool_bar_item, Frecent_keys): Use vcopy.
7569 * lread.c (read_vector): Use ASET.
7570 * msdos.c (Frecent_doskeys): Use vcopy.
7571 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7572 (Finternal_merge_in_global_face): Use ASET and vcopy.
7573 * xfont.c (xfont_list_pattern): Likewise.
7575 2012-08-21 Martin Rudalics <rudalics@gmx.at>
7577 * window.c (Fwindow_point): For the selected window always return
7578 the position of its buffer's point.
7579 (Fset_window_point): For the selected window always go in its
7580 buffer to the specified position.
7582 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7584 Setter macros for fontsets.
7585 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7586 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7587 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7590 2012-08-20 Glenn Morris <rgm@gnu.org>
7592 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7593 Don't assume that `ln -f' works.
7595 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7597 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
7598 and later about non-assignments with no effect. See discussion at
7599 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
7602 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7604 Inline setter functions for Lisp_Objects slots of struct specbinding.
7605 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
7608 2012-08-20 Martin Rudalics <rudalics@gmx.at>
7610 * window.c (select_window): Always make selected window's buffer
7613 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7615 Use AREF and ASET for docstrings of category tables.
7616 * category.h (CATEGORY_DOCSTRING): Use AREF.
7617 (SET_CATEGORY_DOCSTRING): Use ASET.
7618 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
7620 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7622 Inline setter functions for hash table members.
7623 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
7624 (set_hash_hash, set_hash_index): Rename with _slot suffix.
7625 (set_hash_key_and_value, set_hash_index, set_hash_next)
7626 (set_hash_hash): New functions.
7627 * charset.c, fns.c: Adjust users.
7629 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7631 Inline getter and setter functions for per-buffer values.
7632 * buffer.h (per_buffer_default, set_per_buffer_default)
7633 (per_buffer_value, set_per_buffer_value): New functions.
7634 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
7635 * buffer.c, data.c: Adjust users.
7637 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
7639 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
7641 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7643 Rely on <config.h> + <unistd.h> to declare 'environ',
7644 as gnulib does this if the system doesn't.
7645 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7646 Remove declaration. MS-Windows declares it on stdlib.h which is
7647 included by conf_post.h.
7648 * emacs.c (environ) [DOUG_LEA_MALLOC]:
7649 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
7650 * vm-limit.c: Include <unistd.h>, for 'environ'.
7652 * unexaix.c, unexcoff.c: Include "mem-limits.h".
7653 (start_of_data): Remove decl; mem-limits.h provides it.
7655 * xdisp.c (handle_invisible_prop): Make it a bit faster
7656 and avoid a gcc -Wmaybe-uninitialized diagnostic.
7658 2012-08-19 Chong Yidong <cyd@gnu.org>
7660 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
7663 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
7665 * .gdbinit: Use call instead of set when calling a function in the
7668 * data.c (set_internal): Don't use set_blv_found.
7669 (Fkill_local_variable): Likewise.
7671 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
7673 * nsfont.m (ns_ascii_average_width): Ensure the string
7674 ascii_printable is initialized with a null-terminated character
7675 array. Otherwise, it can contain undesired extra characters.
7677 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7679 port new setting code to Sun C 5.8 2005/10/13
7680 * chartab.c, lisp.h (char_table_set, char_table_set_range):
7681 Return void, not Lisp_Object. Otherwise, the compiler
7682 complains about (A?B:C) where B is void and C is Lisp_Object
7683 when compiling CHAR_TABLE_SET, due to the recent change to
7684 the API of sub_char_table_set_contents.
7686 2012-08-18 Chong Yidong <cyd@gnu.org>
7688 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
7689 for the string case (Bug#3874).
7691 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7693 * buffer.h (BSET): Remove (Bug#12215).
7694 Replace all uses with calls to new setter functions.

7722 * category.c (bset_category_table):
7723 * syntax.c (bset_syntax_table):
7724 New setter functions.
7726 * process.h (PSET): Remove (Bug#12215).

8625 Fix macroexp crash on Windows with debugging (Bug#12118).
8626 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8627 checking subscripts; problem introduced with the recent
8628 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8629 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8630 since it's used in non-static inline functions now.
8632 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

8659 (INLINE_HEADER_END): New macros.
8660 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

8684 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
8685 This how ASET and AREF are supposed to work, and makes
8686 it easier to think about future improvements. See
8687 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
8688 * charset.h (set_charset_attr): New function.

9070 (w32_kbd_patch_key, key_event): Use the codepage returned by
9071 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
9072 (key_event): use uChar.UnicodeChar only if
9073 w32_console_unicode_input is non-zero.

9103 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
9104 enumeration constants, as PURE and HEAP are too general, and clash
9105 with other headers and sources, such as gmalloc.c and the
9106 MS-Windows system headers. All users changed.
9108 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9110 Revert last save_excursion_save and save_excursion_restore changes.
9111 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

9121 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
9123 Improve GDB symbol export (Bug#12036).
9124 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
9125 arms of an 'if', not using conditional expressions; otherwise GDB
9126 complains about the types in the unevaluated arm when the argument
9127 is an integer literal.
9128 (xgetint): Simplify expression.
9129 * alloc.c (gdb_make_enums_visible): New constant. This ports to
9130 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
9131 Zaretskii in <http://bugs.gnu.org/12036#13>.
9132 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
9133 needed now that we have gdb_make_enums_visible.
9134 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
9135 (enum enum_USE_LSB_TAG):
9136 New enum types, packaging up enums that need to be exported to GDB.

9160 * lisp.h (struct Lisp_Excursion): New data type.
9161 (PVEC_EXCURSION): New pseudovector type.

9178 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
9179 emacs.c, as this is a more-suitable home. Had this been done earlier
9180 the fix for 12036 would have avoided some of the problems noted in
9181 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
9182 would have been more obvious.
9183 * emacs.c: Do not include <verify.h>; no longer needed.
9184 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
9185 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
9186 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

9190 (DATA_SEG_BITS): Use it.
9191 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
9192 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
9193 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
9194 not be usable in #if. This simplifies things.
9196 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
9198 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
9200 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
9202 Simplify export of symbols to GDB (Bug#12036).
9203 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
9204 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
9205 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
9206 Adjust to changes in lisp.h and emacs.c, by using
9207 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
9208 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
9209 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
9210 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
9211 instead of gdb_valbits.
9212 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
9213 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
9214 instead of gdb_array_mark_flag.
9215 (xboolvector): Get size from $->size, not $->header.size.
9216 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
9217 (xreload, hook-run, hookpost-run): Remove.
9218 * emacs.c: Include <verify.h>.
9219 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
9220 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
9222 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
9223 (gdb_USE_LSB_TAG): New enum constants.
9224 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9225 Also define these as enum constants, so they're visible to GDB.
9226 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
9227 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
9228 as constants, so they're visible to GDB.

9231 Now enum constants, not macros, so they're visible to GDB.
9232 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
9233 more convenient now. All uses changed.
9234 (VALMASK) [USE_LSB_TAG]: Also define in this case.
9235 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
9237 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

9244 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
9245 add argument, tune behavior, and adjust all callers.
9247 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
9249 Use typedef for EMACS_INT, EMACS_UINT.
9250 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
9251 than macros. This simplifies debugging in the usual case, since
9252 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
9253 and it allows expressions involving EMACS_INT casts.
9254 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
9256 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

9266 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
9268 Adjust buffer text indirection counters at the end of Fkill_buffer.
9269 * buffer.c (Fkill_buffer): Adjust indirection counters when the
9270 buffer is definitely dead. This should really fix an issue reported
9271 by Christoph Scholtes again. (Bug#12007).
9272 (init_buffer_once): Initialize indirection counters of
9273 buffer_defaults and buffer_local_symbols (for sanity and safety).
9275 2012-07-24 Eli Zaretskii <eliz@gnu.org>
9277 * xdisp.c (init_iterator): Don't compute dimensions of truncation
9278 and continuation glyphs on tooltip frames, leave them at zero.

9281 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
9283 Simplify copy_overlay.
9284 * buffer.c (copy_overlay): Simplify. Use build_marker.

9306 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9308 Swap buffer text indirection counters in Fbuffer_swap_text.
9309 * buffer.c (Fbuffer_swap_text): Swap indirections too.
9310 This avoids crash reported by Christoph Scholtes at
9311 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
9313 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
9315 * nsmenu.m (Popdown_data): New struct.
9316 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
9318 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
9319 (initWithContentRect): Make imgView and contentView non-static
9320 and autorelease them. Also autorelease img and matrix (Bug#12005).
9321 (dealloc): Remove (Bug#12005).
9323 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
9325 Adjust consing_since_gc when objects are explicitly freed.

9338 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
9340 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
9341 as it's limited by the amount of memory, not by INT_MAX.
9343 2012-07-21 Eli Zaretskii <eliz@gnu.org>
9345 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
9346 in special-event-map. See the discussion at

9405 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
9406 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
9407 Adjust users accordingly.
9408 * font.h (font_open_by_name): Adjust prototype.

9427 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
9428 'for_each_per_buffer_object_at'.
9429 All uses changed. It's better to use upper-case for macros that
9430 cannot be implemented as functions, to give the reader a clue
9431 that they're special.
9433 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
9435 * alloc.c (Fgarbage_collect): Tweak docstring.

9476 * intervals.c (merge_interval_right, merge_interval_left):
9477 Do not zero out this interval if it is absorbed by its children,

9481 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
9483 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
9484 when invoking (make-bool-vector N t) and N is a positive

9997 2012-07-11 Glenn Morris <rgm@gnu.org>
9999 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
10000 since nothing has defined it on these platforms.

10012 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
10014 2012-07-11 John Wiegley <johnw@newartisans.com>
10016 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
10017 function attribute, so we only use it if it exists in the

10022 Avoid call to strlen in fast_c_string_match_ignore_case.
10023 * search.c (fast_c_string_match_ignore_case): Change to use
10024 length argument. Adjust users accordingly.
10025 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
10027 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

10069 * s/aix4-2.h (unix): Remove; no longer needed.
10071 EMACS_TIME simplification (Bug#11875).
10072 This replaces macros (which typically do not work in GDB)
10073 with functions, typedefs and enums, making the code easier to debug.
10074 The functional style also makes code easier to read and maintain.
10075 * systime.h: Include <sys/time.h> on all hosts, not just if
10076 WINDOWSNT, since 'struct timeval' is needed in general.
10077 (EMACS_TIME): Now a typedef, not a macro.
10078 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
10080 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

10088 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
10089 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
10090 not functions. All uses rewritten to use the following, respectively:
10091 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
10092 (add_emacs_time, sub_emacs_time): New functions.
10093 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

10106 * nsmenu.m (ns_update_menubar):
10107 * regex.c (regerror):
10108 Prefer memcpy to strncpy and strncat when either will do.
10109 * fileio.c (Fsubstitute_in_file_name):
10110 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
10111 (menu_separator_name_p):
10112 * nsmenu.m (ns_update_menubar):
10113 Prefer memcmp to strncmp when either will do.
10114 * nsterm.m: Include <ftoastr.h>.
10116 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
10117 Prefer snprintf to strncpy.
10118 * nsterm.m (ns_term_init):
10119 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
10120 * nsterm.m (ns_term_init):
10121 Avoid the need for strncpy, by using build_string or
10122 make_unibyte_string directly. Use dtoastr, not snprintf.
10123 * process.c (Fmake_network_process): Diagnose service names that
10124 are too long, rather than silently truncating them or creating
10125 non-null-terminated names.
10126 (Fnetwork_interface_info): Likewise, for interface names.
10127 * sysdep.c (system_process_attributes) [GNU_LINUX]:
10128 Prefer sprintf to strncat.
10129 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
10130 Prefer vsnprintf to vsprintf + strncpy.
10132 2012-07-10 Glenn Morris <rgm@gnu.org>
10134 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
10135 Clarify fallback case.
10137 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10139 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
10140 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
10141 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
10142 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
10143 where argument type is known to be a Lisp_Cons.
10145 2012-07-10 Tom Tromey <tromey@redhat.com>
10147 * bytecode.c (BYTE_CODE_THREADED): New macro.
10148 (BYTE_CODES): New macro. Replaces all old byte-code defines.
10149 (enum byte_code_op): New type.
10150 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.

10155 Optimize pure C strings initialization.
10156 * lisp.h (make_pure_string): Fix prototype.
10157 (build_pure_c_string): New function, defined as static inline. This
10158 provides a better opportunity to optimize away calls to strlen when
10159 the function is called with compile-time constant argument.
10160 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
10161 argument, adjust users accordingly. Use build_pure_c_string where
10163 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
10164 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
10165 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
10167 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10169 Avoid calls to strlen in miscellaneous functions.
10170 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
10171 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
10172 * lread.c (openp): Likewise.
10174 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10176 Avoid calls to strlen in path processing functions.
10177 * fileio.c (file_name_as_directory): Add comment. Change to add
10178 srclen argument and return the length of result. Adjust users
10180 (directory_file_name): Fix comment. Change to add srclen argument,
10181 swap 1st and 2nd arguments to obey the common convention.
10182 Adjust users accordingly.
10183 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
10185 2012-07-10 Glenn Morris <rgm@gnu.org>
10187 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
10188 Move PENDING_OUTPUT_COUNT definition to configure.
10190 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
10191 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
10192 * s/gnu.h (DATA_START): Move definitions to configure.
10194 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
10195 We include usg5-4-common.h, which defines them both.
10197 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
10198 O_RDONLY already includes it).
10200 Stop ns builds setting the EMACSLOADPATH environment variable.
10201 * nsterm.m (ns_load_path): Rename from ns_init_paths.
10202 Now it does not set EMACSLOADPATH, just returns the load-path string.
10203 * nsterm.h: Update accordingly.
10204 * lread.c [HAVE_NS]: Include nsterm.h.
10205 (init_lread) [HAVE_NS]: Use ns_load_path.
10206 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
10208 2012-07-09 Glenn Morris <rgm@gnu.org>
10210 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
10211 since the included bsd-common.h does so.
10213 Stop ns builds setting the EMACSPATH environment variable.
10214 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
10215 (ns_init_paths): Do not set EMACSPATH.
10216 * nsterm.h (ns_exec_path): Add it.
10217 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
10220 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
10222 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
10224 * process.c (wait_reading_process_output): 'waitchannels' was unset
10225 when read_kbd || !NILP (wait_for_cell); fix this.
10227 Add GCC-style 'const' attribute to functions that can use it.
10228 * character.h (char_resolve_modifier_mask):
10229 * keyboard.h (make_ctrl_char):
10230 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
10231 (init_character_once, next_almost_prime, init_fns, init_image)
10232 (flush_pending_output, init_sound):
10233 * mem-limits.h (start_of_data):
10234 * menu.h (finish_menu_items):

10239 Add decls with ATTRIBUTE_CONST.
10241 Minor improvements to make_formatted_string.
10242 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
10243 where int is good enough, as vsprintf returns an int.
10244 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
10246 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10248 Use make_formatted_string to avoid double length calculation.
10249 * lisp.h (make_formatted_string): New prototype.

10256 (x_report_frame_params): Likewise.
10257 * image.c (gs_load): Likewise.
10258 * minibuf.c (get_minibuffer): Likewise.
10259 * msdos.c (dos_set_window_size): Likewise.
10260 * process.c (make_process): Likewise.

10262 * xsettings.c (apply_xft_settings): Likewise.
10264 2012-07-09 Glenn Morris <rgm@gnu.org>
10266 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
10267 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
10268 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.

10271 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
10273 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10275 Move marker debugging code under MARKER_DEBUG.
10276 * marker.c (MARKER_DEBUG): Move marker debugging code under
10277 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
10278 for bootstrap with --enable-checking (~3x slowdown reported
10279 by Juanma Barranquero <lekktu@gmail.com>).
10280 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
10282 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
10284 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
10285 See <http://bugs.gnu.org/11825#29>.
10287 2012-07-08 Eli Zaretskii <eliz@gnu.org>
10289 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
10290 has no font, use the frame's font. (Bug#11813)
10291 (display_line): Add commentary about displaying truncation glyphs
10293 (produce_special_glyphs): Move here from term.c.
10295 * term.c (produce_special_glyphs): Move to xdisp.c.
10297 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
10300 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
10302 * xdisp.c (display_line): Avoid warning about implicit declaration
10305 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
10307 * lisp.h: Remove empty conditional.
10309 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10311 * lread.c (load_path_check): Now static.
10313 Fix some minor --with-ns problems found by static checking.
10314 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
10315 (x_set_font) [!HAVE_X_WINDOWS]:
10316 * image.c (xpm_load_image) [HAVE_NS]:
10317 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
10318 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
10319 Remove unused local.
10320 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
10321 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
10322 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
10323 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
10324 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
10325 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
10326 Fix pointer signedness problem.
10327 * xfaces.c (FRAME_X_FONT_TABLE):
10328 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
10330 2012-07-07 Glenn Morris <rgm@gnu.org>
10332 * lread.c (load_path_check): New function, split from init_lread.
10333 (init_lread): Reorganize. Motivation:
10334 If EMACSLOADPATH is set, check/warn about that rather than the
10335 defaults, which we are not going to use. Hence we can remove
10336 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
10337 Don't warn if site-lisp directories are missing.
10338 If not installed, start from a blank load-path, since
10339 PATH_LOADSEARCH refers to the eventual installation directories.
10341 2012-07-07 Eli Zaretskii <eliz@gnu.org>
10343 Support truncation and continuation glyphs on GUI frames, when
10344 fringes are disabled. (Bug#11832)
10345 * xdisp.c (init_iterator): Get dimensions of truncation and
10346 continuation glyphs even if on GUI frames.
10347 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10348 or both, are absent.
10349 (start_display, move_it_in_display_line_to): Handle the case of a
10350 GUI frame without a fringe to display continuation or truncation
10352 (insert_left_trunc_glyphs): Support GUI frames: make sure
10353 truncation glyphs overwrite enough glyphs from the current line to
10354 have sufficient space in pixels.
10355 (display_line): Support truncation and continuation glyphs on GUI
10356 frames. If some spare pixels are left on the line after inserting
10357 the truncation glyphs, fill that space with a stretch glyph of a
10358 suitably computed width.
10360 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10361 produce_glyphs, to support GUI sessions.
10363 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10365 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10367 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10369 Do not require float-time's arg to fit in time_t (Bug#11825).
10370 This works better on hosts where time_t is unsigned, and where
10371 float-time is applied to the (negative) difference between two times.
10372 * editfns.c (decode_time_components): Last arg is now double *,
10373 not int *, and means to store all the result as a double, without
10374 worrying about whether the seconds part fits in time_t.
10375 All callers changed.
10376 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10377 All callers changed.
10378 (Ffloat_time): Do not fail merely because the specified time falls
10379 outside of time_t range.
10381 2012-07-07 Glenn Morris <rgm@gnu.org>
10383 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

10408 * w32fns.c (Fx_change_window_property): Doc fix.
10410 * w32fns.c (Fx_window_property): Accept the same arguments as the
10411 X Windows version. Doc fix.
10412 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
10414 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10415 Eli Zaretskii <eliz@gnu.org>
10417 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10418 Windows-specific code from nt/config.nt moved here.
10419 Obsolete settings removed.
10421 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10423 * process.c: Avoid unnecessary calls to gettime.
10424 (wait_reading_process_output): Don't get the time of day
10425 when gobbling data immediately and not waiting, as there's no need
10426 for it in that case. This removes a FIXME.
10428 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10430 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10431 is defined (Bug#11768).
10433 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10435 Fix marker debugging code.

10437 if buffer is not multibyte.
10438 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10439 Call byte_char_debug_check with correct arguments.
10441 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10443 Compile marker debugging code only if ENABLE_CHECKING is defined.
10444 * marker.c (byte_char_debug_check, count_markers):
10445 Use only if ENABLE_CHECKING is defined.
10446 (byte_debug_flag): Remove.
10447 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10448 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
10450 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10452 Avoid code repetition in marker-related functions.
10453 * marker.c (attach_marker): New function.
10454 (Fset_marker, set_marker_restricted, set_marker_both)

10456 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
10457 Consistently rename charno to charpos.
10458 (marker_position): Add eassert.
10459 (marker_byte_position): Convert to eassert.

10475 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
10476 (save_restriction_save): Use build_marker.
10477 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
10478 * window.c (save_window_save): Likewise.
10480 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10482 Do not use Fdelete_overlay in delete_all_overlays
10483 to avoid redundant calls to unchain_overlay.
10484 * buffer.c (drop_overlay): New function.
10485 (delete_all_overlays, Fdelete_overlay): Use it.
10486 * minibuf.c (get_minibuffer): Fix comment.
10488 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10490 Port to OpenBSD 5.1 amd64.
10491 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10492 This is needed for OpenBSD, and should be harmless on all BSD systems.
10493 Also, include <sys/sysctl.h>, as it should be available on all
10494 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10495 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10496 use p_pid member, not kp_proc.pid.
10498 2012-07-06 Glenn Morris <rgm@gnu.org>
10500 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10502 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10504 More xmalloc and related cleanup.

10513 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
10515 Omit needless casts involving void * pointers and allocation.
10516 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10517 as the former is more robust if P's type is changed.
10518 Prefer xzalloc to xmalloc + memset 0.
10519 Simplify malloc-or-realloc to realloc.
10520 Don't worry about xmalloc returning a null pointer.
10521 Prefer xstrdup to xmalloc + strcpy.
10522 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
10524 * keyboard.c (apply_modifiers_uncached): Prefer local array to
10525 alloca of a constant.
10527 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10529 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10530 hscroll is larger than the line width. Fixes long and futile
10531 looping inside extend_face_to_end_of_line (on a TTY) producing
10532 glyphs that are not needed and thrown away.
10534 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10536 * marker.c (set_marker_restricted_both): Simplify by using
10539 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10541 * editfns.c (region_limit): Simplify by using clip_to_bounds.

10550 followed by gtk_box_set_homogeneous (Bug#11768).
10551 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10552 (update_theme_scrollbar_width, xg_create_scroll_bar):
10553 Use gtk_scrollbar_new (Bug#11768).

10555 (is_box_type): New function (Bug#11768).
10556 (xg_tool_item_stale_p): Call is_box_type.
10557 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10558 with default display (Bug#11768).
10560 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10562 * xdisp.c (window_hscroll_limited): New function.
10563 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10564 coordinates when window's hscroll is set to insanely large
10565 values. (Bug#11857)
10567 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

10630 * fileio.c (time_error_value): Check the right error number.
10631 Problem reported by Troels Nielsen in
10632 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10634 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10636 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10637 This should be fixed in a better way; see Eli Zaretskii in
10638 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10639 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10641 * fileio.c (time_error_value): Rename from special_mtime.
10642 The old name's problems were noted by Eli Zaretskii in
10643 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10645 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10646 This variable's comment says Emacs needs at least one GDB-visible
10647 symbol of type enum pvec_type, to work around GDB problems.
10648 The symbol's value doesn't matter.
10650 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10651 that causes compilation to fail on pre-C99 compilers.
10653 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10655 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

10658 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10660 * buffer.c (init_buffer_once): Fix initialization of
10661 headers for buffer_defaults and buffer_local_symbols.
10662 Reported by Juanma Barranquero <lekktu@gmail.com>.
10664 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>

10669 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
10670 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
10671 change in pvec_type.

10679 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10680 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10681 abusing vector->header.next.nbytes.
10682 (live_vector_p): Use PVEC_TYPE.
10683 (mark_object): Adapt code to extract pvectype. Use switch.
10685 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10687 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10688 Tighten new eassert a bit.
10690 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10692 Fix compilation with --enable-gcc-warnings and -O1
10693 optimization level.
10694 * doprnt.c (doprnt): Change type of tem to int, initialize
10695 to avoid compiler warning. Add eassert.
10696 * search.c (simple_search): Initialize match_byte to avoid
10697 compiler warning. Add eassert.
10699 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10701 Avoid weird behavior with large horizontal scrolls.
10702 Without this change, for example, large hscroll values would
10703 mess up Emacs's display on Fedora 15 x86, presumably due to
10704 overflows in int calculations in the display code.
10705 Also, if buffers had long lines, Emacs would freeze.
10706 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10707 (set_window_hscroll): New function, containing the old guts of
10708 Fset_window_hscroll. Return the clipped value.
10709 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10710 This avoids the need to check against PTRDIFF_MAX.
10712 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10714 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10716 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10718 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10720 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10721 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10722 since GCC 4.4.6 issues a bogus warning for them.
10724 Fix bugs in file timestamp newness comparisons.
10725 * fileio.c (Ffile_newer_than_file_p):
10726 * lread.c (Fload): Use full timestamp resolution of files,
10727 not just the 1-second resolution, so that files that are only
10728 slightly newer still count as newer.
10729 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10730 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10732 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10734 * fileio.c: Improve handling of file time marker. (Bug#11852)

10737 Use it to set special mtime values consistently.
10739 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10741 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10742 marker for non-existing file. (Bug#11852)
10744 2012-07-03 Glenn Morris <rgm@gnu.org>
10746 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10747 and did not make it into globals.h).
10749 2012-07-03 Tom Tromey <tromey@redhat.com>

10796 values which aren't power of 2.
10797 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10798 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users

10809 * alloc.c (allocate_vector_block): Remove redundant
10810 calls to mallopt if DOUG_LEA_MALLOC is defined.
10811 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10812 avoid calls to mallopt if zero_vector is returned.
10814 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10816 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10817 is enabled, avoid dereferencing NULL current_sblock if
10820 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10822 Cleanup basic buffer management.
10823 * buffer.h (struct buffer): Change layout to use generic vector
10824 marking code. Fix some comments. Change type of 'clip_changed'
10825 to bitfield. Remove unused #ifndef old.
10826 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10827 (GET_OVERLAYS_AT): Fix indentation.
10828 (for_each_per_buffer_object_at): New macro.
10829 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
10830 (Fbuffer_local_variables): Use it.
10831 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
10832 * alloc.c (allocate_buffer): Adjust to match new layout of
10833 struct buffer. Fix comment.
10834 (mark_overlay): New function.
10835 (mark_buffer): Use it. Use mark_vectorlike to mark normal
10836 Lisp area of struct buffer.
10837 (mark_object): Use it. Adjust marking of misc objects
10838 and related comments.
10840 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10842 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10843 wrapper that is not needed because the wrapped code is a no-op (zero
10844 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10845 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10847 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10849 * alloc.c (mark_buffer): Simplify. Remove prototype.
10850 (mark_object): Add comment. Reorganize marking of vector-like
10851 objects. Use CHECK_LIVE for all vector-like objects except buffers
10852 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10853 Avoid redundant calls to mark_vectorlike for bool vectors.
10855 2012-06-30 Glenn Morris <rgm@gnu.org>
10857 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10859 * epaths.in (PATH_SITELOADSEARCH): New.
10860 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10861 This is rather than relying on --enable-locallisppath elements
10862 having "site-lisp" in their names. (Bug#10208#25, 11658)
10864 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10866 * w32proc.c (sys_select): Accept and ignore one more argument.
10868 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10870 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10871 (pselect) [!MS_DOS]: Redirect to sys_select.
10873 * sysdep.c: Don't include dos.h and dosfns.h.
10875 * process.c (sys_select):
10876 * msdos.c (sys_select): Accept one more argument and ignore it.
10878 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10879 adapt data types and code to that.
10882 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10883 which clashes with the gnulib function of the same name.
10885 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10887 * font.c (font_style_to_value, font_style_symbolic)
10888 (font_prop_validate_style): Add type checks for values in
10891 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10893 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10896 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10898 * xdisp.c (try_window_id): Undo last change.
10900 * w32.c (getwd): Adjust commentary about startup_dir.
10901 (init_environment): Always call sys_access, even in non-MSVC
10902 builds. Don't chdir to the directory of the Emacs executable.
10903 This undoes code from 1997 which was justified by the need to
10904 "avoid conflicts when removing and renaming directories". But its
10905 downside was that every relative file name was being interpreted
10906 relative to the directory of the Emacs executable, which can never
10907 be TRT. In particular, it broke sys_access when called with
10908 relative file names.
10909 (sys_access): Map GetLastError to errno.
10911 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

10917 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10920 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
10922 * gnutls.c (emacs_gnutls_handshake):
10923 Add QUIT to make the loop interruptible.
10925 2012-06-29 Glenn Morris <rgm@gnu.org>
10927 * charset.c (init_charset): Make lack of etc/charsets fatal.
10929 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10931 * editfns.c (region_limit): Fix type mismatch.
10933 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10935 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
10936 undefined. Convert from xassert to eassert.
10937 * nsmenu.m: Convert from xassert to eassert.
10938 * nsterm.m: Likewise.
10940 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

10944 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
10946 Avoid integer overflow on scroll-left and scroll-right.
10947 * window.c (HSCROLL_MAX): New macro.
10948 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
10949 overflow when requested scroll falls outside ptrdiff_t range.
10951 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10953 * window.h (struct window): Change type of 'hscroll',
10954 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
10955 'last_modified' and 'last_overlay_modified' to EMACS_INT.
10956 Adjust users accordingly.
10957 * xdisp.c (try_cursor_movement): Replace type check with eassert.
10958 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
10959 from EMACS_INT to ptrdiff_t.
10960 (make_window): Omit redundant initialization.

10978 enabled with --enable-checking=[all,glyphs] configure option.
10979 Fix GLYPH_DEBUG usage assuming that it may be undefined,
10980 adjust comments accordingly.

11029 * alloc.c (allocate_string_data): Remove dead code.
11030 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to

11101 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
11103 Use sprintf return value instead of invoking strlen on result.
11104 In the old days this wasn't portable, since some sprintf
11105 implementations returned char *. But they died out years ago and
11106 Emacs already assumes sprintf returns int.
11107 Similarly for float_to_string.
11108 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

11114 * xdisp.c (message_dolog):
11115 * xfns.c (syms_of_xfns):
11116 Use sprintf or float_to_string result to avoid need to call strlen.
11117 * data.c (Fnumber_to_string):
11118 Use make_unibyte_string, since the string must be ASCII.
11119 * lisp.h, print.c (float_to_string): Now returns int length.
11120 * term.c (produce_glyphless_glyph):
11121 Use sprintf result rather than recomputing it.
11123 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

11152 * xfns.c (x_window): Remove redundant cast.
11154 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
11156 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
11157 `const char *' to `char *' to avoid compiler warning.
11159 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11161 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
11162 instead of truncating it to 63 (admittedly a generous limit).
11164 * process.c: Fix spelling and caps in comments.
11166 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
11168 * emacs.c (setpgrp): Remove definition, unused.

11215 Remove unnecessary forward decls.
11217 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11219 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

11221 * dispnew.c (Fsleep_for, sit_for):
11222 * keyboard.c (kbd_buffer_get_event):
11223 * process.c (Faccept_process_output):
11224 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
11225 This improves on the previous patch, which introduced a bug
11226 when time_t is unsigned and as wide as intmax_t.
11227 See <http://bugs.gnu.org/9000#51>.

11287 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
11288 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
11289 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
11290 Don't assume EMACS_TIME and struct timeval are the same type.
11292 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
11294 Support higher-resolution time stamps (Bug#9000).
11295 The time stamps are only nanosecond-resolution at the C level,
11296 since that's the best that any real-world system supports now.
11297 But they are picosecond-resolution at the Lisp level, as that's
11298 easy, and leaves room for future OS improvements.
11300 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
11303 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
11304 Don't get current time unless it's needed.
11306 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
11307 now provides it if it's absent.
11308 (start_atimer): Port to higher-res time stamps.
11309 Check for time stamp overflow. Don't get current time more
11310 often than is needed.
11312 * buffer.h (struct buffer): Buffer modtime now has high resolution.
11313 Include systime.h, not time.h.
11314 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
11316 * dired.c: Include stat-time.h.
11317 (Ffile-attributes): File times now have higher resolution.
11319 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
11320 (struct image): Timestamp now has higher resolution.
11322 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
11323 has at least microseconds now. All uses removed.
11324 (update_frame, update_single_window, update_window, update_frame_1)
11325 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
11326 (duration_to_sec_usec): Remove; no longer needed.
11328 * editfns.c (time_overflow): Now extern.
11329 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)

11335 (make_time): Now static.
11336 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
11337 Report an error if the time is invalid, rather than having the caller
11340 * fileio.c: Include <stat-time.h>
11341 (Fcopy_file): Copy higher-resolution time stamps.
11342 Prefer to set the time stamp via a file descriptor if that works.
11343 (Fset_file_times, Finsert_file_contents, Fwrite_region)
11344 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
11345 (Fvisited_file_modtime, Fset_visited_file_modtime):
11346 Support higher-resolution time stamps.
11348 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
11350 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
11352 * image.c (prepare_image_for_display, clear_image_cache)
11353 (lookup_image): Port to higer-resolution time stamps.
11355 * keyboard.c (start_polling, bind_polling_period):
11356 Check for time stamp overflow.
11357 (read_char, kbd_buffer_get_event, timer_start_idle)
11358 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
11359 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
11360 Port to higher-resolution time stamps. Do not assume time_t is signed.
11361 (decode_timer): New function. Timers are now vectors of length 9,
11362 not 8, to accommodate the picosecond component.
11363 (timer_check_2): Use it.
11365 * nsterm.m (select_timeout, timeval_subtract): Remove.
11366 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
11367 as they're a bit more accurate and handle overflow better.
11368 (ns_select): Change prototype to be compatible with pselect.
11369 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11370 * nsterm.h (ns_select): Adjust prototype.
11372 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
11373 us-resolution time stamps.
11374 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
11376 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
11378 * lisp.h (time_overflow): New decl.
11379 (wait_reading_process_output): First arg is now intmax_t, not int,
11380 to accommodate larger waits.
11382 * process.h (struct Lisp_Process.read_output_delay):
11383 Now counts nanoseconds, not microseconds.
11384 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
11386 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
11387 (wait_reading_process_output):
11388 Port to ns-resolution time stamps.
11389 (Faccept_process_output, wait_reading_process_output):
11390 Check for time stamp overflow. Do not assume time_t is signed.
11391 (select_wrapper): Remove; we now use pselect.
11392 (Fprocess_attributes): Now generates ns-resolution time stamps.
11394 * sysdep.c: Include utimens.h. Don't include utime.h
11395 or worry about struct utimbuf; gnulib does that for us now.
11396 (gettimeofday): Remove; gnulib provides a substitute.
11397 (make_timeval): New function.
11398 (set_file_times): Now sets ns-resolution time stamps.
11399 New arg FD; all uses changed.
11400 (time_from_jiffies, ltime_from_jiffies, get_up_time)
11401 (system_process_attributes):
11402 Now returns ns-resolution time stamp. All uses changed.
11403 Check for time stamp overflow.
11405 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
11406 provides a substitute now.
11408 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11409 since it guarantees struct timespec.
11410 (EMACS_TIME): Now struct timespec, so that we can support
11411 ns-resolution time stamps.
11412 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11413 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11414 (EMACS_USECS): Remove.
11415 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11416 so multiply the arg by 1000 before storing it.
11417 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
11419 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
11420 Port to ns-resolution time stamps.
11421 (EMACS_TIME_NEG_P): Remove; replaced by....

11425 (set_file_times, make_time, lisp_time_argument): Adjust signature.
11426 (make_timeval, make_lisp_time, decode_time_components): New decls.
11427 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11428 that it mishandled time_t overflow. You can't compare by subtracting!
11429 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11430 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
11432 * term.c: Include <sys/time.h>.
11433 (timeval_to_Time): New function, for proper overflow wraparound.
11434 (term_mouse_position, term_mouse_click): Use it.
11436 * undo.c (record_first_change): Support higher-resolution time stamps
11437 in the undo buffer.
11438 (Fprimitive_undo): Use them when restoring time stamps.
11440 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
11441 (w32_get_internal_run_time):
11442 Port to higher-resolution Emacs time stamps.
11443 (ltime): Now accepts single 64-bit integer, as that's more convenient
11446 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
11448 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
11449 for compatibility with pselect. Support ns-resolution time stamps.
11451 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
11453 * xselect.c (wait_for_property_change, x_get_foreign_selection):
11454 Check for time stamp overflow, and support ns-resolution time stamps.
11456 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
11457 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
11458 (timeval_subtract): Remove; no longer needed.
11459 (XTflash, XTring_bell, x_wait_for_event):
11460 Port to ns-resolution time stamps. Don't assume time_t is signed.

11466 2012-06-22 Eli Zaretskii <eliz@gnu.org>
11468 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
11469 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11470 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11471 staticidx goes up to 1597 out of 1600 = 0x640.)
11473 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11475 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.

11487 access to `contents' member of Lisp_Vector objects with AREF and ASET
11490 2012-06-19 Chong Yidong <cyd@gnu.org>
11492 * frame.c (delete_frame): When selecting a frame on a different
11493 text terminal, do not alter the terminal's top-frame.

11496 frame's selected window and its terminal's top-frame.
11497 (unwind_format_mode_line): Restore them.
11498 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
11500 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,

11502 (prepare_menu_bars): Likewise.
11504 * term.c (Ftty_top_frame): New function.
11506 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

11509 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
11510 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
11511 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
11512 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

11521 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11522 gets killed during executing of this function (Bug#11665).
11523 Try to always return Qt when the buffer has been actually killed.
11524 (Vkill_buffer_query_functions): In doc-string say that functions
11525 run by this hook should not change the current buffer.
11527 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11529 Fix recently-introduced process.c problems found by static checking.
11530 * process.c (write_queue_push, write_queue_pop, send_process):

11549 * lisp.h (eassert): Assume C89 or later.
11550 This removes the need for CHECK.
11551 (CHECK): Remove. Its comments about always evaluating its
11552 argument were confusing, as 'eassert' typically does not evaluate
11555 * coding.c (produce_chars): Use ptrdiff_t, not int.
11557 * xterm.c (x_draw_underwave): Check for integer overflow.
11558 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

11727 * s/gnu.h (POSIX_SIGNALS): Remove (not used since 2010-05-04).
11729 2012-06-13 Paul Eggert <eggert@cs.ucla.edu>
11731 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
11732 * alloc.c (make_number) [!defined make_number]:
11733 Remove, as lisp.h always defines this now.
11734 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
11735 (roundup_size): Verify that it is a power of 2.
11736 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
11737 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
11738 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
11739 -DUSE_LSB_TAG=0, to override the automatically-selected default.
11740 USE_LSB_TAG now is always defined to be either 0 or 1.
11742 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
11743 code works fine either way, and efficiency is not a concern here,
11744 as the union type is for debugging, not for production.
11745 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
11746 Use an inline function on all platforms when using the union type,
11747 since this is simpler and 'static inline' can be used portably
11749 (LISP_INITIALLY_ZERO): New macro.
11750 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
11751 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.
11753 2012-06-12 Glenn Morris <rgm@gnu.org>

11778 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
11779 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
11780 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.
11782 2012-06-11 Stefan Monnier <monnier@iro.umontreal.ca>
11784 * alloc.c (make_byte_code): New function.
11785 (Fmake_byte_code): Use it. Don't purify here.

11817 2012-06-09 Michael Albinus <michael.albinus@gmx.de>
11819 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
11820 dbus_type_is_basic if available.
11821 (xd_extract_signed, xd_extract_unsigned): Rename from
11822 extract_signed and extract_unsigned, respectively. Adapt callers.

11833 * xdisp.c (vmessage): Treat frame message as multibyte.
11834 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
11835 would generate the diagnostic "Making \302\247 buffer-local while
11838 2012-06-08 Eli Zaretskii <eliz@gnu.org>
11840 * dispnew.c (showing_window_margins_p): Undo last change, which
11841 was done due to an inadvertent commit.
11842 (adjust_frame_glyphs_for_frame_redisplay): Do call

11851 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
11853 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
11854 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
11856 2012-06-08 Eli Zaretskii <eliz@gnu.org>
11858 * alloc.c (allocate_vectorlike): Fix last change.
11860 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
11862 Block-based vector allocation of small vectors.
11863 * lisp.h (struct vectorlike_header): New field `nbytes',
11864 adjust comment accordingly.
11865 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
11866 to denote vector blocks. Adjust users (live_vector_p,
11867 mark_maybe_pointer, valid_lisp_object_p) accordingly.
11868 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
11869 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),

11889 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
11891 * doprnt.c (doprnt): Truncate multibyte char correctly.
11892 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
11893 would mishandle a string argument "Xc" if X was a multibyte
11894 character of length 2: it would truncate after X's first byte
11895 rather than including all of X.
11897 2012-06-06 Chong Yidong <cyd@gnu.org>
11899 * buffer.c (word_wrap): Doc fix.
11901 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

11927 position is past the end of the mode line string.
11929 * buffer.c (buffer_local_value_1): New function, split from
11930 Fbuffer_local_value; can return Qunbound.

11946 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11948 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11949 Convert pctcpu and pctmem to Lisp float properly.
11950 Let the compiler fold better, as 100.0/0x8000 is exact.
11952 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11954 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
11957 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

11961 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
11963 For a 'struct window', replace some Lisp_Object fields to
11964 bitfields where appropriate, remove unused fields.
11965 * window.h (struct window): Remove unused 'last_mark_x' and
11966 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11967 change its type from Lisp_Object to bitfield.
11968 Change type of 'force_start', 'optional_new_start',
11969 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
11970 fields from Lisp_Object to bitfield. Adjust users accordingly.
11972 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11974 Pacify gcc -Wdouble-precision when using Xaw.
11975 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11976 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11977 Use 'float' consistently, rather than 'float' in most places
11978 and 'double' in a couple of places.
11980 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11982 * xdisp.c (handle_stop): Detect whether we have overlay strings
11983 loaded by testing it->current.overlay_string_index to be
11984 non-negative, instead of checking whether n_overlay_strings is
11985 positive. (Bug#11587)
11987 2012-05-31 Chong Yidong <cyd@gnu.org>
11989 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

11993 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11995 * search.c (search_buffer): Remove calls to
11996 r_alloc_inhibit_buffer_relocation, as it is now called by
11997 maybe_unify_char, which was the cause of relocation of buffer text
12000 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12002 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
12003 for the duration of call to load_charset, to avoid problems with
12004 callers of maybe_unify_char that access buffer text through C
12007 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
12008 decrement the inhibition flag, instead of just setting or
12011 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12013 Remove obsolete '#define static' cruft.
12014 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
12015 This #undef was "temporary" in 2000; it is no longer needed
12016 now that '#define static' has gone away.
12017 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
12018 (gray_bitmap_bits): Remove; no longer needed.
12019 All uses replaced with definiens.

12027 Define only on platforms that need it.
12028 * emacs.c: Include <sys/gmon.h> when profiling.
12029 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
12030 (__executable_start): Remove decl, since lisp.h does it now.
12031 (safe_bcopy): Remove decl; no longer has that name.
12032 (main): Coalesce #if into single bit of code, for simplicity.
12033 Cast pointers to uintptr_t, since standard libraries want integers
12035 * lisp.h (__executable_start): New decl.
12037 2012-05-31 Glenn Morris <rgm@gnu.org>
12039 * image.c (Fimagemagick_types): Doc fix.

12062 Do not create empty overlays with the evaporate property (Bug#9642).
12063 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
12064 Bug#9642, but explicitly check that the buffer the overlay would
12065 be moved to is live and rearrange lines to make sure that errors
12066 will not put the overlay in an inconsistent state.
12067 (Fdelete_overlay): Cosmetics.
12069 2012-05-28 Eli Zaretskii <eliz@gnu.org>
12071 * w32term.c (my_bring_window_to_top): New function.
12072 (x_raise_frame): Use handle returned by DeferWindowPos, which
12073 could be different from the original one.

12083 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
12085 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
12086 This avoids undefined behavior that might cause the eassert
12087 to not catch an out-of-range value.
12089 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
12091 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

12103 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
12105 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
12106 Only r_alloc_inhibit_buffer_relocation needed to be added;
12107 the others were already declared.
12109 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
12110 before checking whether it's out of range. Put the check inside
12112 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
12114 2012-05-27 Ken Brown <kbrown@cornell.edu>
12116 * callproc.c (Fcall_process): Restore a line that was accidentally
12117 commented out in the 2011-02-13 change (bug#11547).

12121 * lisp.h [REL_ALLOC]: Add prototypes for external functions
12122 defined on ralloc.c.
12124 * buffer.c [REL_ALLOC]: Remove prototypes of
12125 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
12126 they are now on lisp.h.
12128 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
12130 * search.c (search_buffer): Use it to inhibit relocation of buffer
12131 text while re_search_2 is doing its job, because re_search_2 is
12132 passed C pointers to buffer text. (Bug#11519)
12134 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
12135 Update value to 24.
12137 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
12138 state after an additional call to move_it_in_display_line_to, keep
12139 the values of it->max_ascent and it->max_descent found for the
12141 (pos_visible_p): Revert the comparison against bottom_y to what it
12142 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
12145 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12147 Fix coding-related core dumps with gcc -ftrapv.
12148 The code was computing A - B, where A and B are pointers, and B is
12149 random garbage. This can lead to core dumps on platforms that
12150 have special pointer registers, and it also leads to core dumps on
12151 x86-64 when compiled with gcc -ftrapv. The fix is to compute
12152 A - B only when B is initialized properly.
12153 * coding.c (coding_set_source, coding_set_destination): Return void.
12154 (coding_change_source, coding_change_destinations): New functions,
12155 with the old behaviors of coding_set_source and coding_set_destination.
12156 All callers that need an offset changed to use these new functions.

12166 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
12168 * w32console.c: Include window.h.
12169 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
12171 (initialize_w32_display): Initialize mouse-highlight data.
12173 * w32inevt.c: Include termchar.h and window.h.
12174 (do_mouse_event): Support mouse-autoselect-window. When the mouse
12175 moves, call note_mouse_highlight. If help_echo changed, call
12176 gen_help_event to produce help-echo message in the echo area.
12177 Call clear_mouse_face if mouse_face_hidden is set in the mouse
12180 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12182 * lread.c (read1): Simplify slightly to avoid an overflow warning

12185 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12187 * bidi.c (bidi_mirror_char): Revert last change: an int is
12188 definitely wide enough here.
12190 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
12192 Fix integer width and related bugs (Bug#9874).
12193 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
12194 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
12195 (string_bytes, check_sblock, allocate_string_data):
12196 (compact_small_strings, Fmake_bool_vector, make_string)

12202 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12203 (allocate_pseudovector):
12204 Use int, not EMACS_INT, where int is wide enough.
12205 (inhibit_garbage_collection, Fgarbage_collect):
12206 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12207 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
12208 int might not be wide enough.
12209 (bidi_cache_search, bidi_cache_find, bidi_init_it)
12210 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
12211 (bidi_at_paragraph_end, bidi_find_paragraph_start)

12215 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
12216 (Fkill_buffer, Fset_buffer_major_mode)
12217 (advance_to_char_boundary, Fbuffer_swap_text)
12218 (Fset_buffer_multibyte, overlays_at, overlays_in)

12224 (Foverlay_recenter, last_overlay_modification_hooks_used)
12225 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
12226 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12227 (validate_region): Omit unnecessary test for b <= e,
12228 since that's guaranteed by the previous test.
12229 (adjust_overlays_for_delete): Avoid pos + length overflow.
12230 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
12231 (report_overlay_modification):
12232 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12233 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
12234 Omit pointer cast, which isn't needed anyway, and doesn't work
12235 after the EMACS_INT -> ptrdiff_t change.
12236 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
12237 * buffer.h: Adjust decls to match defn changes elsewhere.
12238 (struct buffer_text, struct buffer):

12242 not int, to avoid needless 32-bit limit on 64-bit hosts.
12243 (exec_byte_code): Use tighter memory-full test, one that checks
12244 for alloca overflow. Don't compute the address of the object just
12245 before an array, as that's not portable. Use EMACS_INT, not
12246 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
12247 * callint.c (Fcall_interactively):
12248 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12249 * callproc.c (call_process_kill, Fcall_process):
12250 Don't assume pid_t fits into an Emacs fixnum.
12251 (call_process_cleanup, Fcall_process, child_setup):

12258 * casefiddle.c (casify_object, casify_region, operate_on_word)
12259 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
12260 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12261 (casify_object): Avoid integer overflow when overallocating buffer.
12262 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
12263 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
12264 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
12265 * category.h (CATEGORYP): Don't assume arg is nonnegative.
12266 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
12267 integers are now checked earlier. All uses replaced with XINT.
12269 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12270 For CCL_MapSingle, check that content and value are in int range.
12271 (ccl_driver, Fregister_code_conversion_map):
12272 Check that Vcode_version_map_vector is a vector.
12273 (resolve_symbol_ccl_program): Check that vector header is in range.
12274 Always copy the vector, so that we can check its contents reliably
12275 now rather than having to recheck each instruction as it's being
12276 executed. Check that vector words fit in 'int'.
12277 (ccl_get_compiled_code, Fregister_ccl_program)
12278 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
12279 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
12280 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
12281 contents are in range.
12282 (Fccl_execute_on_string): Check that status is in range.
12283 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
12284 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
12285 Accept and return EMACS_INT, not int, because callers can pass values
12286 out of 'int' range.
12287 (c_string_width, strwidth, lisp_string_width, chars_in_text)
12288 (multibyte_chars_in_text, parse_str_as_multibyte)

12290 (str_as_unibyte, str_to_unibyte, string_count_byte8)
12291 (string_escape_byte8, Fget_byte):
12292 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12293 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
12294 avoid mishandling large integers.
12295 * character.h: Adjust decls to match defn changes elsewhere.
12296 * charset.c (load_charset_map_from_file, find_charsets_in_text)

12301 Don't assume fixnum fits in int.
12302 (load_charset_map_from_vector, Fmap_charset_chars):
12303 Remove now-unnecessary CHECK_NATNUMs.
12304 (Fdefine_charset_internal): Check ranges here, more carefully.
12305 Don't rely on undefined behavior with signed left shift overflow.
12306 Don't assume unsigned int fits into fixnum, or that fixnum fits
12307 into unsigned int. Don't require max_code to be a valid fixnum;
12308 that's not true for gb10830 4-byte on a 32-bit host. Allow
12309 invalid_code to be a cons, for the same reason. Require code_offset
12310 to be a character. Avoid int overflow if max_char is close
12312 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
12313 this is intended anyway and avoids some undefined behavior.
12314 (load_charset_map): Pass unsigned, not int, as 2nd arg of
12315 INDEX_TO_CODE_POINT, as that's what it expects.
12316 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
12317 * charset.h (DECODE_CHAR): Return int, not unsigned;
12318 this is what was intended anyway, and it avoids undefined behavior.
12319 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
12320 integer-overflow issues.
12321 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
12322 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
12323 where the argument is EMACS_INT, and this behavior is not intended.
12324 * chartab.c (Fmake_char_table, Fset_char_table_range)
12325 (uniprop_get_decoder, uniprop_get_encoder):
12326 Don't assume fixnum fits in int.
12327 * cmds.c (move_point): New function, that does the gist of
12328 Fforward_char and Fbackward_char, but does so while checking
12329 for integer overflow more accurately.
12330 (Fforward_char, Fbackward_char): Use it.
12331 (Fforward_line, Fend_of_line, internal_self_insert)
12332 (internal_self_insert):
12333 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12334 Fix a FIXME, by checking for integer overflow when calculating
12335 target_clm and actual_clm.

12392 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):

12980 * xterm.c (x_x_to_emacs_modifiers):
12981 Don't assume EMACS_INT overflows nicely into int.
12982 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
12983 may come from Lisp.
12984 (handle_one_xevent): NATNUMP can eval its arg twice.
12985 (x_connection_closed):
12986 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

13000 (unreadpure): Remove function.
13001 (readevalloop): Don't call read_list with -1 flag.

13014 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
13016 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
13019 This directory predates autoconf and is no longer needed nowadays.
13020 Move its few remaining bits of functionality to where they're needed.
13021 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

13024 * Makefile.in (M_FILE): Remove. All uses removed.
13025 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
13026 * lisp.h (USE_LSB_TAG):
13027 * mem-limits.h (EXCEEDS_LISP_PTR):
13028 Use VAL_MAX, not VALBITS, in #if.
13029 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
13030 (EMACS_UINT): Define unconditionally now.
13031 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
13032 (BITS_PER_EMACS_INT): New constants, replacing
13033 what used to be in config.h, but not useful in #if.
13034 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
13035 define them any more.
13036 (VAL_MAX): New macro.
13038 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
13039 BITS_PER_EMACS_INT, in #if.
13040 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
13041 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
13042 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:

13044 Move here from removed file m/intel386.h.
13045 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
13046 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
13048 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
13050 Assume C89 or later.
13051 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.

13075 * xfns.c (x_in_use): Remove `static' qualifier.
13076 * xterm.h (x_in_use): Declare.
13077 * xgselect.c: Include xterm.h.
13078 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
13079 and `display_arg' (bug#9754).
13081 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>

13101 * search.c (Fword_search_regexp, Fword_search_backward)
13102 (Fword_search_forward, Fword_search_backward_lax)
13103 (Fword_search_forward_lax): Move functions to isearch.el
13104 (bug#10145, bug#11381).
13106 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
13108 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
13110 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
13112 * lread.c (init_obarray): Declare Qt and Qnil as special.
13114 2012-05-14 Glenn Morris <rgm@gnu.org>
13116 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
13117 Put "libexec" before "bin", for the sake of init_callproc_1.
13119 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13121 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
13123 * unexaix.c: Port to more-recent AIX compilers.
13124 (report_error, report_error_1, make_hdr, copy_sym)
13125 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
13126 Make arguments const char *, not char *, to avoid violations of C
13127 standard and to fix some AIX warnings reported by Gilles Pion.
13129 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13131 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
13132 already have overlays loaded.
13133 (handle_single_display_spec): Before returning without displaying
13134 fringe bitmap, synchronize the bidi iterator with the main display
13135 iterator, by calling iterate_out_of_display_property.
13136 (iterate_out_of_display_property): Detect buffer iteration by
13137 testing that it->string is a Lisp string.
13138 (get_next_display_element): When the current object is exhausted,
13139 and there's something on it->stack, call set_iterator_to_next to
13140 proceed with what's on the stack, instead of returning zero.
13141 (set_iterator_to_next): If called at the end of a Lisp string,
13142 proceed to consider_string_end without incrementing string
13143 position. Don't increment display vector index past the end of
13144 the display vector. (Bug#11417)
13145 (pos_visible_p): Don't report a position visible when move_it_to
13146 stopped at the last line of window, which happens to be scanned
13147 backwards by the bidi iteration. (Bug#11464)
13149 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13151 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
13152 and right-margin display specs even if the spec is invalid or we
13153 are on a TTY, and thus unable to display on the fringes.
13154 That's because the text with the property will not be displayed anyway,
13155 so we need to signal to the caller that this is a "replacing"
13156 display spec. This fixes display when the spec is invalid or we
13159 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13161 * unexaix.c (make_hdr): Fix typo in prototype.
13162 This bug broke the build on AIX. Problem reported by Gilles Pion.
13164 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
13166 * keyboard.c (kbd_buffer_get_event): Read special events also in
13167 batch mode. (Bug#11415)
13169 2012-05-12 Glenn Morris <rgm@gnu.org>
13171 * ns.mk: Update for ns_appbindir no longer having trailing "/".
13173 2012-05-12 Eli Zaretskii <eliz@gnu.org>
13175 * lisp.mk (lisp): Add newcomment.elc.
13177 2012-05-12 Glenn Morris <rgm@gnu.org>
13179 * Makefile.in (MKDIR_P): New, set by configure.
13180 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
13182 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
13184 Remove unused function hourglass_started.
13185 * dispextern.h (hourglass_started):
13186 * w32fns.c (hourglass_started):
13187 * xdisp.c (hourglass_started): Remove.
13189 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
13191 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
13192 Update dependencies.
13194 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
13196 * xgselect.c (xg_select): Put maxfds+1 into a var.
13197 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
13199 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
13201 2012-05-10 Dave Abrahams <dave@boostpro.com>
13203 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
13204 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
13206 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
13208 * dbusbind.c (xd_registered_buses): New internal Lisp object.
13209 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
13210 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
13211 Initialize xd_registered_buses.
13213 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
13215 Untag more efficiently if USE_LSB_TAG.
13216 This is based on a proposal by YAMAMOTO Mitsuharu in
13217 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
13218 For an admittedly artificial (nth 8000 longlist) benchmark on
13219 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
13220 Emacs's overall text size by 1%.
13221 * lisp.h (XUNTAG): New macro.
13222 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
13223 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
13224 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
13225 * eval.c (Fautoload):
13226 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
13227 * frame.h (XFRAME): Use XUNTAG.
13229 Port recent dbusbind.c changes to 32-bit --with-wide-int.
13230 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
13231 Remove unportable assumptions about print widths of types like
13233 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
13234 intptr_t when converting between pointer and integer, to avoid GCC
13235 warnings about wrong width.
13237 2012-05-09 Eli Zaretskii <eliz@gnu.org>
13239 * w32proc.c (new_child): Force Windows to reserve only 64KB of
13240 stack for each reader_thread, instead of defaulting to 8MB
13241 determined by the linker. This avoids failures in creating

13245 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
13247 Fix up display of the *Minibuf-0* buffer in the mini window.
13248 * keyboard.c (read_char): Don't clear the echo area if there's no
13250 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
13251 contents of *Minibuf-0*) if there's no message displayed in its stead.
13253 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
13255 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
13258 2012-05-06 Chong Yidong <cyd@gnu.org>
13260 * lisp.mk (lisp): Update.
13262 2012-05-05 Jim Meyering <meyering@redhat.com>
13264 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
13266 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
13268 * data.c (PUT_ERROR): New macro.
13269 (syms_of_data): Use it. Add new error type `user-error'.
13270 * undo.c (user_error): New function.
13271 (Fprimitive_undo): Use it.
13272 * print.c (print_error_message): Adjust print style for `user-error'.
13273 * keyboard.c (user_error): New function.
13274 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
13276 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
13278 Do not limit current-time-string to years 1000..9999.
13279 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
13280 (Fcurrent_time_string): Support any year that is supported by the
13281 underlying localtime representation. Don't use asctime, as it
13282 has undefined behavior for years outside the range -999..9999.
13284 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
13286 Fix race conditions involving setenv, gmtime, localtime, asctime.
13287 Without this fix, interrupts could mess up code that uses these
13288 nonreentrant functions, since setting TZ invalidates existing
13289 tm_zone or tzname values, and since most of these functions return
13290 pointers to static storage.
13291 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
13292 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
13293 Grow the critical sections to include not just invoking
13294 localtime/gmtime, but also accessing these functions' results
13295 including their tm_zone values if any, and any related TZ setting.
13296 (format_time_string): Last arg is now struct tm *, not struct tm **,
13297 so that the struct tm is saved in the critical section.
13298 All callers changed. Simplify allocation of initial buffer, partly
13299 motivated by the fact that memory allocation needs to be outside
13300 the critical section.
13302 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
13304 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
13305 with RESET_INTERVAL.
13307 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
13308 Remove duplicated buffer name initialization.
13310 2012-05-02 Jim Meyering <jim@meyering.net>
13312 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
13314 * xfns.c (x_window): Use xstrdup (Bug#11375).
13316 2012-05-02 Eli Zaretskii <eliz@gnu.org>
13318 * xdisp.c (pos_visible_p): If already at a newline from the
13319 display string before the 'while' loop, don't walk back the glyphs
13320 from it3.glyph_row. Solves assertion violation when the display
13321 string begins with a newline (egg.el). (Bug#11367)
13323 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
13325 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
13328 2012-05-01 Glenn Morris <rgm@gnu.org>
13330 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
13331 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
13332 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
13333 All were removed before 23.1.
13335 * dispnew.c: Remove HAVE_LIBNCURSES test;
13336 it is always true on relevant platforms.
13338 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
13339 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
13341 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
13343 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
13345 * .gdbinit (xpr): Remove checks for no longer existing misc types.
13346 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
13349 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
13351 Do not avoid creating empty evaporating overlays (Bug#9642).
13352 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13353 That is, do not delete an evaporating overlay if it becomes
13354 empty after its bounds are adjusted to fit within its buffer.
13355 This fix caused other problems, and I'm reverting it until we get
13356 to the bottom of them.
13358 2012-04-27 Chong Yidong <cyd@gnu.org>
13360 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
13362 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13364 * xdisp.c (pos_visible_p): If the window start position is beyond
13365 ZV, start the display from buffer beginning. Prevents assertion
13366 violation in init_iterator when the minibuffer window is scrolled
13367 via the scroll bar.
13369 * window.c (window_scroll_pixel_based): Likewise.
13371 2012-04-27 Chong Yidong <cyd@gnu.org>
13373 * keymap.c (where_is_internal): Doc fix (Bug#10872).
13375 2012-04-27 Glenn Morris <rgm@gnu.org>
13377 * fileio.c (Fcopy_file, Fset_file_selinux_context):
13378 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13380 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13382 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13383 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13385 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13387 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
13388 display element, check also the underlying string or buffer
13389 character. (Bug#11341)
13391 * w32menu.c: Include w32heap.h.
13392 (add_menu_item): If the call to AppendMenuW (via
13393 unicode_append_menu) fails, disable Unicode menus only if we are
13394 running on Windows 9X/Me.
13396 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13398 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13399 (xgetint): Add missing shift for LSB tags.
13401 2012-04-24 Martin Rudalics <rudalics@gmx.at>
13403 * keyboard.c (read_char): Don't wipe echo area for select window
13404 events: These might get delayed via `mouse-autoselect-window'
13407 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
13409 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
13410 manipulation of :loaded-from data.
13412 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
13414 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
13415 now a cons (bug#11311).
13417 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
13419 Do not create empty overlays with the evaporate property (Bug#9642).
13420 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13421 if it becomes empty after its bounds are adjusted to fit within
13422 its buffer. Without this fix, in a nonempty buffer (let ((o
13423 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13424 yields an empty overlay that has the evaporate property, which is
13425 not supposed to happen.
13427 Fix minor GTK3 problems found by static checking.
13428 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

13447 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
13448 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13449 (__malloc_size_t, __malloc_ptrdiff_t):
13450 Remove. All uses removed, replaced by the definiens if needed,
13451 since we can assume C89 or better now.
13452 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
13453 (protect_malloc_state, align, get_contiguous_space)

13459 (special_realloc, _realloc_internal_nolock, _realloc_internal)
13460 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
13461 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
13462 Define using prototypes, not old style.

13543 (list_system_processes, system_process_attributes) [__FreeBSD__]:
13544 Use Emacs indenting style more consistently. Avoid some casts.
13545 Use 'double' consistently rather than mixing 'float' and 'double'.
13547 2012-04-21 Eduard Wiebe <usenet@pusto.de>
13549 * sysdep.c (list_system_processes, system_process_attributes):

13584 row, return zero immediately.
13585 (try_cursor_movement): If inside continuation line, don't back up
13586 farther than the first row after the header line, if any.
13587 Don't consider the header-line row as "partially visible", even if

13626 New extern decls, to avoid calling undeclared functions.
13627 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
13628 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
13629 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13630 (NEED_MEM_INSERT): New macro.
13631 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13632 Remove one incorrect comment and fix another.

13635 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
13636 * ralloc.c (ALIGNED, ROUND_TO_PAGE, HEAP_PTR_SIZE)
13637 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
13638 (r_alloc_sbrk): Now static.
13640 Improve ralloc.c interface checking.
13641 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
13642 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)

13646 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
13647 Remove decls. This fixes an "It stinks!".
13649 * alloc.c (which_symbols): Fix alignment issue / type clash.
13651 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
13653 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
13654 (struct Lisp_Misc_Any): Likewise.

13668 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
13669 * s/netbsd.h, s/sol2-6.h:
13670 Remove definition of GC_MARK_STACK, since the default now works.
13671 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
13672 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
13673 no longer the default.
13674 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
13676 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
13678 * lread.c (lisp_file_lexically_bound_p):
13679 Fix hang at ";-*-\n" (bug#11238).
13681 2012-04-14 Eli Zaretskii <eliz@gnu.org>
13683 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
13684 "unchanged" if its end.pos is beyond ZV. (Bug#11199)
13686 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
13688 * nsterm.m (constrainFrameRect): Always constrain when there is only
13689 one screen (Bug#10962).

13693 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
13695 2012-04-13 Reuben Thomas <rrt@sc3d.org>
13697 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
13699 2012-04-11 Daniel Colascione <dancol@dancol.org>
13701 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13702 against is gone. It's better to use vfork now so that when Cygwin
13703 gains a new, working vfork, we use it automatically (bug#10398).
13705 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
13707 * window.c (save_window_save): Obey window-point-insertion-type.

13720 (force_quit_count): New var.
13721 (handle_interrupt): Use it.
13723 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
13725 * w32.c (w32_delayed_load): Record the full path of the library
13726 being loaded (bug#10424).
13728 2012-04-09 Glenn Morris <rgm@gnu.org>
13730 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
13731 not just in the obarray, before snarfing them. (Bug#11036)
13733 * Makefile.in ($(leimdir)/leim-list.el):
13734 Pass EMACS rather than BUILT_EMACS.
13736 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
13738 * process.c (make_process):
13739 * process.h: Add integer `gnutls_handshakes_tried' member to
13742 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
13743 Add convenience `GNUTLS_LOG2i' macro.
13745 * gnutls.c (gnutls_log_function2i): Convenience log function.
13746 (emacs_gnutls_read): Use new log functions,
13747 `gnutls_handshakes_tried' process member, and
13748 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
13749 attempts per process (connection).
13751 2012-04-09 Chong Yidong <cyd@gnu.org>
13753 * eval.c (Fuser_variable_p, user_variable_p_eh)
13754 (lisp_indirect_variable): Functions deleted.
13755 (Fdefvar): Caller changed.
13757 * callint.c (Finteractive, Fcall_interactively):
13758 * minibuf.c (Fread_variable): Callers changed.
13760 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13762 * xdisp.c (set_cursor_from_row): If the display string appears in
13763 the buffer at position that is closer to point than the position
13764 after the display string, display the cursor on the first glyph of
13765 the display string. Fixes cursor display when a 'display' text
13766 property immediately follows invisible text. (Bug#11094)
13768 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13770 composite.c: use 'double' consistently
13771 * composite.c (get_composition_id): Use 'double' consistently
13772 instead of converting 'float' to 'double' and vice versa; this is
13773 easier to understand and avoids a GCC warning.
13775 2012-04-09 Glenn Morris <rgm@gnu.org>
13777 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13778 preparation for dumping it with emacs. (Bug#4789)
13779 (leimdir): New variable.
13780 ($(leimdir)/leim-list.el): New rule.
13781 (emacs$(EXEEXT)): Depend on leim-list.el.
13783 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)
13784 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
13785 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
13787 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
13789 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
13792 2012-04-07 Juanma Barranquero <lekktu@gmail.com>
13794 * xml.c (init_libxml2_functions) [WINDOWSNT]:
13795 Remove unused local variable.
13797 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
13799 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
13800 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
13801 (mark_memory): Mark Lisp_Objects only if pointers might hide in
13802 objects, as mark_maybe_pointer will catch them otherwise.
13803 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
13804 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
13806 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
13808 Fix typo that broke non-Windows builds.
13809 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
13811 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13813 Support building on MS-Windows with libxml2.
13815 * makefile.w32-in (OBJ2): Add xml.$(O).
13816 (GLOBAL_SOURCES): Add xml.c.
13817 ($(BLD)/xml.$(O)): New dependency list.
13819 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
13820 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
13821 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
13822 [!WINDOWSNT]: New macros.
13823 (init_libxml2_functions, libxml2_loaded_p): New functions.
13824 (parse_region): Call fn_xmlCheckVersion instead of using the macro
13825 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
13826 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
13827 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13829 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13830 Call init_libxml2_functions before calling libxml2 functions.
13831 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13833 * emacs.c: Don't include libxml/parser.h.
13834 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
13835 xmlCleanupParser directly.
13837 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
13839 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13841 * indent.c (Fvertical_motion): If there is a display string at
13842 point, use it.vpos to compute how many lines to backtrack after
13843 move_it_to point. (Bug#11133)
13845 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13847 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13848 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13849 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13850 macros related to unification of CJK characters. For the details,
13851 see the discussion following the message here:
13852 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
13854 2012-04-04 Chong Yidong <cyd@gnu.org>
13856 * keyboard.c (Vdelayed_warnings_list): Doc fix.
13858 2012-04-01 Eli Zaretskii <eliz@gnu.org>
13860 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
13861 instead of alloca. (Bug#11138)
13863 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
13865 * w32menu.c (is_simple_dialog): Properly check lisp types.
13868 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13870 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13871 position we get to after a call to move_it_to fails the
13872 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13873 only if we wind up in a string from display property. (Bug#11063)
13875 * window.c (Fdelete_other_windows_internal): Invalidate the row
13876 and column information about mouse highlight, so that redisplay
13877 restores it after reallocating the glyph matrices. (Bug#7464)
13879 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13880 string comes from a `display' text property, use the buffer
13881 position of that property as if we actually saw that position in
13883 (move_it_by_lines): Remove the assertion that
13884 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13885 violated when there's a before-string at the beginning of a line.
13888 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13890 * xdisp.c (append_space_for_newline): If the default face was
13891 remapped, use the remapped face for the appended newline.
13892 (extend_face_to_end_of_line): Use the remapped default face for
13893 extending the face to the end of the line.
13894 (display_line): Call extend_face_to_end_of_line when the default
13895 face was remapped. (Bug#11068)
13897 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13899 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
13901 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13903 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
13905 2012-03-27 Glenn Morris <rgm@gnu.org>
13907 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
13910 2012-03-26 Kenichi Handa <handa@m17n.org>
13912 * dispextern.h (struct glyph): Fix previous change. Change the
13913 bit length of glyphless.ch to 25 (Bug#11082).
13915 2012-03-26 Chong Yidong <cyd@gnu.org>
13917 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13918 (command_loop_1): Use it; inhibit selection update for
13919 handle-select-window too (Bug#8996).
13921 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
13923 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13925 2012-03-25 Kenichi Handa <handa@m17n.org>
13927 * dispextern.h (struct glyph): Change the bit length of
13928 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13930 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13932 * s/ms-w32.h (tzname): Include time.h before redirecting to
13933 _tzname. Fixes the MSVC build. (Bug#9960)
13935 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
13937 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13940 * xterm.c (XTread_socket): Only modify handling_signal if
13941 !SYNC_INPUT. (Bug#11080)
13943 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13945 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13946 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13947 when fetching a multibyte character consumes more bytes than
13948 CHAR_BYTES returns, due to unification of CJK characters in
13949 string_char. (Bug#11073)
13951 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13953 * process.c (wait_reading_process_output): Handle pty disconnect
13954 by refraining from sending oneself a SIGCHLD (bug#10933).
13956 2012-03-22 Chong Yidong <cyd@gnu.org>
13958 * dispextern.h (struct it): New member string_from_prefix_prop_p.
13960 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
13961 Mark string as coming from a prefix property.
13962 (handle_face_prop): Use default face for prefix strings (Bug#4281).
13963 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
13965 2012-03-21 Chong Yidong <cyd@gnu.org>
13967 * xfaces.c (Vface_remapping_alist): Doc fix.
13969 2012-03-20 Eli Zaretskii <eliz@gnu.org>
13971 * w32proc.c (Fw32_set_console_codepage)
13972 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
13975 2012-03-20 Chong Yidong <cyd@gnu.org>
13977 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
13978 to reflect default non-nil value of redisplay-dont-pause.
13980 2012-03-19 Kenichi Handa <handa@m17n.org>
13982 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
13983 it fit in a valid range (Bug#11003).
13985 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13987 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13988 that is not from display property, accept the row as a "cursor
13989 row" if one of the string's character has a non-nil `cursor'
13990 property. Fixes cursor positioning when there are newlines in
13991 overlay strings, e.g. in icomplete.el. (Bug#11035)
13993 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13995 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13997 2012-03-12 Chong Yidong <cyd@gnu.org>
13999 * eval.c (inhibit_lisp_code): Rename from
14000 inhibit_window_configuration_change_hook; move from window.c.
14002 * xfns.c (unwind_create_frame_1, Fx_create_frame):
14003 * window.c (run_window_configuration_change_hook)
14004 (syms_of_window): Callers changed.
14006 2012-03-11 Chong Yidong <cyd@gnu.org>
14008 * keymap.c (Fkey_description): Doc fix (Bug#9700).
14010 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
14012 2012-03-10 Chong Yidong <cyd@gnu.org>
14014 * frame.c (other_visible_frames): Don't assume the selected frame
14015 is visible (Bug#10955).
14017 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
14019 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
14021 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
14023 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
14024 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
14027 2012-03-03 Glenn Morris <rgm@gnu.org>
14029 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
14031 2012-03-02 Eli Zaretskii <eliz@gnu.org>
14033 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
14034 position past the first glyph_row that ends at ZV. (Bug#10902)
14035 (redisplay_window, next_element_from_string): Fix typos in
14037 (redisplay_window): Pass to move_it_vertically the margin in
14038 pixels, not in screen lines.
14040 2012-03-02 Glenn Morris <rgm@gnu.org>
14042 * buffer.c (buffer-list-update-hook): Doc fix.
14044 2012-02-29 Eli Zaretskii <eliz@gnu.org>
14046 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
14047 push_it before setting up the iterator for the first overlay
14048 string, even if we have an empty string loaded.
14049 (next_overlay_string): If there's an empty string on the iterator
14050 stack, pop the stack. (Bug#10903)
14052 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
14054 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
14055 Suggested by Stefan Monnier in
14056 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
14057 * alloc.c (widen_to_Lisp_Object): New static function.
14058 (mark_memory): Also mark Lisp_Objects by fetching pointer words
14059 and widening them to Lisp_Objects. This would work even if
14060 USE_LSB_TAG is defined and wide integers are used, which might
14061 happen in a future version of Emacs.
14063 2012-02-25 Chong Yidong <cyd@gnu.org>
14065 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
14068 * xselect.c (Fx_selection_exists_p): Doc fix.
14069 (x_clipboard_manager_save_all): Print an informative message
14070 before saving to clipboard manager.
14072 2012-02-24 Chong Yidong <cyd@gnu.org>
14074 * keyboard.c (process_special_events): Handle all X selection
14075 requests in kbd_buffer, not just the next one (Bug#8869).
14077 2012-02-23 Chong Yidong <cyd@gnu.org>
14079 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
14080 call when setting menu-bar-lines and tool-bar-lines parameters.
14081 (unwind_create_frame_1): New helper function.
14083 * window.c (inhibit_window_configuration_change_hook): New var.
14084 (run_window_configuration_change_hook): Obey it.
14085 (syms_of_window): Initialize it.
14087 2012-02-22 Chong Yidong <cyd@gnu.org>
14089 * xterm.c (x_draw_image_relief): Add missing type check for
14090 Vtool_bar_button_margin (Bug#10743).
14092 2012-02-21 Chong Yidong <cyd@gnu.org>
14094 * fileio.c (Vfile_name_handler_alist): Doc fix.
14096 * buffer.c (Fget_file_buffer): Protect against invalid file
14097 handler return value.
14099 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
14101 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
14102 when computing $valmask.
14104 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
14105 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
14106 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
14107 It's useless in that case, and it can cause problems on hosts
14108 that allocate halves of EMACS_INT values separately.
14109 Reported by Dan Horák. Diagnosed by Andreas Schwab in
14110 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
14111 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
14112 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
14113 it avoids undefined behavior on hosts where shifting right by more
14114 than the word width has undefined behavior.
14116 2012-02-19 Chong Yidong <cyd@gnu.org>
14118 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
14119 (Funhandled_file_name_directory, Ffile_name_as_directory)
14120 (Fdirectory_file_name, Fexpand_file_name)
14121 (Fsubstitute_in_file_name): Protect against invalid file handler
14122 return values (Bug#10845).
14124 2012-02-18 Eli Zaretskii <eliz@gnu.org>
14126 * .gdbinit (pitx): Fix incorrect references to fields of the
14129 2012-02-17 Chong Yidong <cyd@gnu.org>
14131 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
14133 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
14135 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
14136 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
14138 2012-02-15 Chong Yidong <cyd@gnu.org>
14140 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
14141 marked as special. Also, starting docstrings with * is obsolete.
14143 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>

14731 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
14732 verifies glyph row's hash code--we have just reallocated the

14897 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
14898 is set, removing the need for VIRT_ADDRESS_VARIES.
14899 (PURE_P): Use a more-efficient implementation that needs just one

14906 consistency with the new puresize.h.
14907 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
14908 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

14914 (erase_phys_cursor, update_window_cursor, show_mouse_face)
14915 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
14916 behave as if the cursor position were at the window margin.
14918 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14919 and the cursor position is out of bounds, behave as if the cursor
14920 position were at the window margin. (Bug#10075)
14922 2011-11-18 Chong Yidong <cyd@gnu.org>
14924 * window.c (Fwindow_combination_limit): Make first argument

14945 * xdisp.c (row_hash): New function, body extracted from
14946 compute_line_metrics.
14947 (compute_line_metrics): Call row_hash, instead of computing the
14950 * dispnew.c (verify_row_hash): Call row_hash for computing the
14951 hash code of a row, instead of duplicating code from xdisp.c.
14953 * dispextern.h (row_hash): Add prototype.
14955 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
14957 * frame.c (delete_frame): Don't delete the terminal when the last

15006 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
15007 with user-defined heap size. Bump the default size of the temacs

15011 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
15012 current_matrix and desired_matrix. (Bug#9990)
15013 (verify_row_hash) [XASSERTS]: New function.

15058 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
15060 Avoid some portability problems by eschewing 'extern inline' functions.
15061 The trivial performance wins aren't worth the portability hassles; see
15062 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
15064 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

15112 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
15113 This is also needed for porting to any host where GC_MARK_STACK is
15114 not GC_MAKE_GCPROS_NOOPS.
15115 (which_symbols): Use it.
15117 2011-11-07 Kenichi Handa <handa@m17n.org>

15130 * xmenu.c (cleanup_widget_value_tree): New function.
15131 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
15132 calling free_menubar_widget_value_tree directly (Bug#9830).
15134 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
15136 Fix some portability problems with 'inline'.

15138 (window_box_width, window_box_left, window_box_left_offset)
15139 (window_box_right, window_box_right_offset): Declare extern.
15140 Otherwise, these inline functions do not conform to C99 and
15141 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
15142 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
15143 * intervals.c (adjust_intervals_for_insertion)
15144 (adjust_intervals_for_deletion): Now extern, because otherwise the
15145 extern inline functions 'offset_intervals' couldn't refer to it.
15146 (static_offset_intervals): Remove.
15147 (offset_intervals): Rewrite using the old contents of
15148 static_offset_intervals. The old version didn't conform to C99
15149 because an extern inline function contained a reference to an
15150 identifier with static linkage.
15152 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
15154 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

15172 (Fwindow_vscroll): Doc fix.
15173 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
15174 argument, since it makes no sense to pass a live window and for
15175 consistency with window-child.

15203 (unwind_create_frame): New function (Bug#9943).
15204 (Fx_create_frame): Restructure code to be more similar to the one in
15205 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
15206 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
15207 Move terminal->reference_count++ just before making the frame official

15216 official. Move initialization of image_cache_refcount and
15217 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

15257 previous/next-single-property-change returns nil, treat that as
15258 the beginning or the end of the buffer. (Bug#9955)
15260 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
15262 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

15385 (w32font_open_internal, compute_metrics):
15386 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
15387 instead of calling the "wide" APIs directly.
15389 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
15391 * w32.h (syms_of_w32font): Add prototype.
15393 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

15397 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
15398 (Fmove_to_window_line): Doc fix.
15400 2011-10-27 Chong Yidong <cyd@gnu.org>
15402 * process.c (make_process): Set gnutls_state to NULL.
15404 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
15405 non-NULL, regardless of GNUTLS_INITSTAGE.

15454 (bidi_resolve_weak): Don't enter the expensive loop if the current
15455 position is before next_en_pos. Record the bidi type of the first
15456 non-ET, non-BN character we find, in addition to its position.
15457 (bidi_level_of_next_char): Invalidate next_en_type when
15458 next_en_pos is over-stepped.
15460 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
15462 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15463 * editfns.c: Rewrite current-time-zone so that it invokes
15464 the equivalent of (format-time-string "%Z") to get the time zone name.
15465 This fixes a bug when the time zone name contains characters that
15466 need converting from the system time locale to Emacs internal format.
15467 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15468 that patch fixed format-time-string to do the conversion, but
15469 I forgot to fix current-time-zone.
15470 (format_time_string): New function, containing most of
15471 what Fformat_time_string used to contain.
15472 (Fformat_time_string): Rewrite in terms of format_time_string.
15473 This doesn't change this function's behavior.
15474 (current-time-zone): Rewrite to use format_time_string.
15475 This fixes the bug reported by Michael Schierl in
15476 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15477 Jason Rumney's 2007-06-07 change worked around this bug, but
15479 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15481 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15483 * xdisp.c (start_display): If the character at POS is displayed
15484 via a display vector, reset IT->current.dpvec_index to zero.
15485 (try_window_reusing_current_matrix): If a line ends in a display
15486 vector or the next line starts in a display vector, continue
15487 redrawing the window even though the character position of
15488 start_row was reached.
15491 2011-10-18 Chong Yidong <cyd@gnu.org>
15493 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15494 with nobreak-char-display too.
15496 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15498 Fix part 3 of bug#9771.
15499 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15500 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15501 non-neutral characters if the current character is a paragraph
15502 separator (a.k.a. Newline). This avoids running the same
15503 expensive loop twice, once when we consume the preceding newline
15504 and the other time when the line actually needs to be displayed.
15505 Avoid the loop when we see neutrals on the base embedding level
15506 following a character whose directionality is the same as the
15507 paragraph's. This avoids running the expensive loop when a line
15508 ends in a long sequence of neutrals, like control characters.
15509 Add assertion against STRONG_AL type. Slightly rearrange code
15510 that determines the type of a neutral given the first non-neutral
15512 (bidi_level_of_next_char): Set next_en_pos to zero when
15513 invalidating its info.
15515 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15517 * xdisp.c (push_display_prop): Determine whether to record string
15518 or buffer position by IT->string, not by IT->method. Allow
15519 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15520 (move_it_vertically_backward): Don't look for character position
15521 immediately after the newline when in a continuation line.
15524 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15526 * window.c (coordinates_in_window): Rewrite and delabelize
15527 vertical border check. (Bug#5357) (Bug#9618)
15529 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
15531 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15532 errors in XSetWindowBorder (bug#9310).
15534 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15536 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15537 avoid crash when xmalloc overrun checking is enabled.
15539 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15541 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15542 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15543 cursor motion with <left> and <right> arrow keys.
15545 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15546 some callers set that themselves.
15548 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15550 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15551 display string and the previous row comes from the same string and
15552 is empty. (Bug#9739) (Bug#9738)
15554 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15556 * doc.c (get_doc_string): Encode file name (bug#9735).
15558 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15560 * bidi.c (bidi_level_of_next_char):
15561 * xdisp.c (get_visually_first_element): Remove old incorrect
15562 comments regarding the Unicode Line Separator character.
15564 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15566 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15568 * alloc.c (Fgc_status): Do not access beyond zombies array
15569 boundary if nzombies > MAX_ZOMBIES.
15570 * alloc.c (dump_zombies): Add missing format specifier.
15572 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15574 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15575 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15577 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15578 Some packages use them to denote characters with modifiers.
15580 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15582 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15583 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15584 matching a pp-number. Rename parameter var to var1.
15586 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15588 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15590 2011-10-08 Glenn Morris <rgm@gnu.org>
15592 * callint.c (Fcall_interactively): Give a more explicit error for the
15593 'c' case with a non-character input. (Bug#8479)
15595 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15597 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15599 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15600 lines that are hscrolled on the left.
15602 * dispnew.c (buffer_posn_from_coords): Account for a possible
15603 presence of header-line. (Bug#4426)
15605 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15607 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15608 Don't advertise functionality which we discourage or doesn't work.
15610 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15612 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15613 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15614 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15615 this makes Emacs dump core during garbage collection on rare
15616 occasions. sizeof is obviously inferior to offsetof here, so
15617 stick with offsetof.
15618 (GC_POINTER_ALIGNMENT): New macro.
15619 (mark_memory): Omit 3rd (offset) arg; caller changed.
15620 Don't assume EMACS_INT alignment is the same as pointer alignment.
15622 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15624 * keyboard.c (read_key_sequence_remapped): New var.
15625 (read_key_sequence): Compute remapping in the right buffer.
15626 (command_loop_1): Use read_key_sequence's remapping directly.
15628 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15630 * dired.c (file_name_completion): Don't expand file name.
15631 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15632 before checking file name handler.
15634 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15635 they've been requested explicitly (bug#9591).
15637 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15639 * keymap.c (Fsingle_key_description): Use make_specified_string
15640 instead of build_string to build string from push_key_description.
15643 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15645 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15646 This fixes a Y2038 bug on 64-bit hosts.
15647 * buffer.c (reset_buffer):
15648 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15649 (Fclear_buffer_auto_save_failure):
15650 Use 0, not -1, to represent an unset failure time, since time_t
15651 might not be signed.
15653 Remove dependency on glibc malloc internals.
15654 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15655 Move back here from lisp.h, but with their new implementations.
15656 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15657 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15658 * charset.c (charset_table_init): New static var.
15659 (syms_of_charset): Use it instead of xmalloc. This removes a
15660 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15661 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15662 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15663 Move back to alloc.c.
15664 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15665 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15667 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15669 * nsterm.m (windowDidResize): Call x_set_window_size only when
15670 ns_in_resize is true. Otherwise set pixelwidth/height and
15671 call change_frame_size (Bug#9628).
15673 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15675 Port --enable-checking=all to Fedora 14 x86-64.
15676 * charset.c (syms_of_charset): Also account for glibc malloc's
15677 internal overhead when calculating the initial malloc maximum.
15679 Port --enable-checking=all to Fedora 14 x86.
15680 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15682 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15683 (overrun_check_realloc, overrun_check_free):
15684 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15685 That way, xmalloc returns a properly-aligned pointer even if
15686 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15687 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15688 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15689 into account when calculating the initial malloc maximum.
15690 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15691 Move here from alloc.c, so that charset.c can use it too.
15692 Properly align; the old code wasn't right for common 32-bit hosts
15693 when configured with --enable-checking=all.
15694 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15695 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15697 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15699 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15702 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15704 * xdisp.c (compute_display_string_end): If there's no display
15705 string at CHARPOS, return -1.
15707 * bidi.c (bidi_fetch_char): When compute_display_string_end
15708 returns a negative value, treat the character as a normal
15709 character not covered by a display string. (Bug#9624)
15711 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15713 * lread.c (Fread_from_string): Fix typo in docstring.
15715 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15717 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15718 newline, reseat the iterator instead of bidi-iterating there one
15719 character at a time. (Bug#9610)
15720 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15721 TO_CHARPOS if the bidi iterator is at base embedding level.
15723 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15725 * lread.c (readevalloop): Use correct code for NBSP.
15726 (read1): Likewise. (Bug#9608)
15728 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15730 * dbusbind.c (Fdbus_register_signal): When service is not
15731 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15733 2011-09-25 Glenn Morris <rgm@gnu.org>
15735 * buffer.c (truncate-lines): Doc fix.
15737 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15739 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15740 (Fset_window_next_buffers): Doc fix.
15742 2011-09-24 Glenn Morris <rgm@gnu.org>
15744 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15746 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15748 Fix minor problems found by static checking.
15749 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
15750 * indent.c (Fvertical_motion): Fix == vs = typo.
15752 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15754 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15755 Default value is now t. Doc fix.
15757 * indent.c (Fvertical_motion): Compute and apply the overshoot
15758 logic when moving up, not only when moving down. Fix the
15759 confusing name and values of the it_overshoot_expected variable;
15760 logic changes accordingly. (Bug#9254) (Bug#9549)
15762 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15763 CHARPOS is covered by a display string which includes newlines.
15764 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15765 is covered by a display string with embedded newlines.
15767 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15769 * dbusbind.c (Fdbus_register_signal): Add match rule to
15770 Vdbus_registered_objects_table. (Bug#9581)
15771 (Fdbus_register_method, Vdbus_registered_objects_table):
15774 2011-09-24 Jim Meyering <meyering@redhat.com>
15776 do not ignore write error for any output size
15777 The previous change was incomplete.
15778 While it makes emacs --batch detect the vast majority of stdout
15779 write failures, errors were still ignored whenever the output size is
15780 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15781 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15782 && echo FAIL: ignored write error
15783 FAIL: ignored write error
15784 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15785 && echo FAIL: ignored write error
15786 FAIL: ignored write error
15787 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15789 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15791 * emacs.c (Fkill_emacs): In noninteractive mode exit
15792 non-successfully if a write error occurred on stdout. (Bug#9574)
15794 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15796 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15799 * dispextern.h (struct it): Update the comment documenting what
15802 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15804 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15805 a display string, extend search for cursor position to end of row.
15806 (find_row_edges): If the row ends in a newline from a display
15807 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15808 Handle the case of a display string with multiple newlines.
15809 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15810 non-empty line. Fixes confusing cursor motion with arrow keys at
15811 the beginning of a line that starts with whitespace.
15813 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15815 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15818 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15820 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15821 boolean (Bug#9154).
15823 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15825 * xdisp.c (display_line): Record maximum and minimum buffer
15826 positions even if no glyphs were produced (e.g., by a zero-width
15827 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15828 buffer positions that will be removed from the glyph row because
15830 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15831 column is beyond frame width: don't subtract 1 "pixel" when
15832 computing width of the stretch.
15833 (reseat_at_next_visible_line_start): Undo the change made on
15834 2011-09-17 that saved paragraph information and restored it after
15835 the call to `reseat'. (Bug#9545)
15837 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15839 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15840 and turn window cursor on if cleared (Bug#9415).
15842 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15844 * search.c (boyer_moore): Take unibyte characters from pattern
15845 literally. (Bug#9458)
15847 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15849 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
15851 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
15853 Fix minor problem found by static checking.
15854 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
15855 initialized, to pacify gcc -Wuninitialized.
15857 * fileio.c: Report proper errno when syscall falls.
15858 (Finsert_file_contents): Save and restore errno,
15859 so that report_file_error outputs the correct diagnostic.
15860 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15862 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15864 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15866 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15868 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15869 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
15871 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15873 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15874 about the current paragraph and restore it after the call to reseat.
15876 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15877 (bidi_find_paragraph_start): Search back for paragraph beginning
15878 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15879 (bidi_move_to_visually_next): Only trigger paragraph-related
15880 computations when the last character is a newline or at EOB, not
15881 just any NEUTRAL_B. (Bug#9470)
15883 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15884 truncated lines if point is covered by a display string. (Bug#9524)
15886 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15888 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15889 (cons_to_x_long): New function.
15890 (lisp_data_to_selection_data): Use it. Correct the test for
15891 short-versus-long data; it was negated. Break out of vector
15892 loop, for efficiency, when a long datum is discovered.
15894 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15896 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15898 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15900 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
15901 GCC PR/17406) by declaring this function with external scope.
15903 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15905 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
15906 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
15908 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
15910 * editfns.c (Fformat): Correctly handle text properties on "%%".
15912 2011-09-15 Eli Zaretskii <eliz@gnu.org>
15914 * xterm.c (x_draw_composite_glyph_string_foreground):
15915 * w32term.c (x_draw_composite_glyph_string_foreground):
15916 * term.c (encode_terminal_code):
15917 * composite.c (composition_update_it, get_composition_id):
15918 * xdisp.c (get_next_display_element)
15919 (fill_composite_glyph_string): Add comments about special meaning
15920 of TAB characters in a composition.
15922 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15924 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15925 This occurs when processing a multibyte format.
15926 Problem reported by Wolfgang Jenker.
15928 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15930 * xdisp.c (try_cursor_movement): Only check for exact match if
15931 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15933 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15935 Remove unused external symbols.
15936 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15937 * xdisp.c (calc_pixel_width_or_height): Now static.
15938 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
15939 * indent.c (check_display_width):
15940 * w32term.c: Fix comment to match code.
15941 * xterm.c, xterm.h (x_catching_errors): Remove.
15943 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15945 * xselect.c: Use signed conversions more consistently (Bug#9498).
15946 (selection_data_to_lisp_data): Assume incoming selection data are
15947 signed integers, not unsigned. This is to be consistent with
15948 outgoing selection data, which was modified to use signed integers
15949 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15950 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15951 expects long, not unsigned long.
15953 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15955 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15956 computation of loop end. Reported by Johan Bockgård

15961 * frame.c (Fother_visible_frames_p): Function deleted.
15963 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15965 * indent.c (compute_motion): Process display vector front to back
15966 rather than the other way around. (Bug#2496)
15968 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15970 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15972 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15974 * minibuf.c (Fread_from_minibuffer): Doc fix.
15976 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15978 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15979 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15981 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15983 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15984 value for non-existent files.
15986 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15988 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15989 set its "size" to -1. This will set the modtime_size field of
15990 the corresponding buffer to -1, which is what
15991 verify-visited-file-modtime expects for files that do not exist.
15994 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15996 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15998 * lisp.h: ... from here. push_key_description is no longer
15999 defined in keyboard.c, so its declaration should not be in
16000 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
16001 logically belongs with push_key_description.
16003 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
16005 * buffer.h: Include <sys/types.h> instead of <time.h>.
16006 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
16007 Problem reported by Herbert J. Skuhra.
16009 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
16011 * xml.c (parse_region): Make the parsing work for
16012 non-comment-starting XML files again (bug#9144).
16014 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
16016 * image.c (gif_load): Fix calculation of bottom and right corner.
16019 2011-09-10 Eli Zaretskii <eliz@gnu.org>
16021 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
16022 redisplay in small windows.
16024 2011-09-09 Eli Zaretskii <eliz@gnu.org>
16026 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
16028 2011-09-08 Martin Rudalics <rudalics@gmx.at>
16030 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
16031 Operate on live windows only.
16033 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
16035 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
16037 2011-09-07 Eli Zaretskii <eliz@gnu.org>
16039 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
16040 only under bidi iteration.
16042 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
16044 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
16046 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16048 isnan: Fix porting problem to Solaris 10 with bundled gcc.
16049 Without this fix, the command to link temacs failed due to an
16050 undefined symbol __builtin_isnan. This is because
16051 /usr/include/iso/math_c99.h #defines isnan(x) to
16052 __builtin_isnan(x), but the bundled gcc, which identifies itself
16053 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
16055 * floatfns.c (isnan): #undef, and then #define to a clone of
16057 (Fisnan): Always define, since it's always available now.
16058 (syms_of_floatfns): Always define isnan at the Lisp level.
16060 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16062 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
16064 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16066 * fileio.c: Fix bugs with large file offsets (Bug#9428).
16067 The previous code assumed that file offsets (off_t values) fit in
16068 EMACS_INT variables, which is not true on typical 32-bit hosts.
16069 The code messed up by falsely reporting buffer overflow in cases
16070 such as (insert-file-contents "big" nil 1 2) into an empty buffer
16071 when "big" contains more than 2**29 bytes, even though this
16072 inserts just one byte and does not overflow the buffer.
16073 (Finsert_file_contents): Store file offsets as off_t
16074 values, not as EMACS_INT values. Check for overflow when
16075 converting between EMACS_INT and off_t. When checking for
16076 buffer overflow or for overlap, take the offsets into account.
16077 Don't use EMACS_INT for small values where int suffices.
16078 When checking for overlap, fix a typo: ZV was used where
16079 ZV_BYTE was intended.
16080 (Fwrite_region): Don't assume off_t fits into 'long'.
16081 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
16083 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
16085 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
16087 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16089 sprintf-related integer and memory overflow issues (Bug#9412).
16091 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
16092 (esprintf, exprintf, evxprintf): New functions.
16093 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
16094 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
16095 (modify_event_symbol): Do not assume that the length of
16096 name_alist_or_stem is safe to alloca and fits in int.
16097 (Fexecute_extended_command): Likewise for function name and binding.
16098 (Frecursion_depth): Wrap around reliably on integer overflow.
16099 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
16100 since some callers pass EMACS_INT values.
16101 (Fsingle_key_description): Don't crash if symbol name contains more
16102 than MAX_ALLOCA bytes.
16103 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
16104 (get_minibuffer): Arg is now EMACS_INT, not int.
16105 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
16106 (esprintf, exprintf, evxprintf): New decls.
16107 * window.h (command_loop_level, minibuf_level): Reflect API changes.
16109 * dbusbind.c (signature_cat): New function.
16110 (xd_signature, Fdbus_register_signal):
16111 Do not overrun buffer; instead, report string overflow.
16113 * dispnew.c (add_window_display_history): Don't overrun buffer.
16114 Truncate instead; this is OK since it's just a log.
16116 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
16117 even if the time zone offset is outlandishly large.
16118 Don't mishandle offset == INT_MIN.
16120 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
16121 when creating daemon; the previous buffer-overflow check was incorrect.
16123 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
16124 which has the guts of the old verror function.
16126 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
16127 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
16129 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
16130 (font_unparse_xlfd): Don't blindly alloca long strings.
16131 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
16132 fits in int, when using sprintf. Use single snprintf to count
16133 length of string rather than counting it via multiple sprintfs;
16134 that's simpler and more reliable.
16135 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
16136 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
16137 sprintf, in case result does not fit in int.
16139 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
16140 (fontset_from_font): Print it.
16142 * frame.c (tty_frame_count): Now printmax_t, not int.
16143 (make_terminal_frame, set_term_frame_name): Print it.
16144 (x_report_frame_params): In X, window IDs are unsigned long,
16145 not signed long, so print them as unsigned.
16146 (validate_x_resource_name): Check for implausibly long names,
16147 and don't assume name length fits in 'int'.
16148 (x_get_resource_string): Don't blindly alloca invocation name;
16149 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
16152 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
16153 (xg_check_special_colors, xg_set_geometry):
16154 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
16156 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
16157 Use esprintf, not sprintf, in case result does not fit in int.
16159 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16160 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
16161 it as a large positive number.
16162 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
16163 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16165 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
16166 in case result does not fit in int.
16168 * print.c (float_to_string): Detect width overflow more reliably.
16169 (print_object): Make sprintf buffer a bit bigger, to avoid potential
16170 buffer overrun. Don't assume list length fits in 'int'. Treat
16171 print length of 0 as 0, not as infinity; to be consistent with other
16172 uses of print length in this function. Don't overflow print length
16173 index. Don't assume hash table size fits in 'long', or that
16174 vectorlike size fits in 'unsigned long'.
16176 * process.c (make_process): Use printmax_t, not int, to format
16177 process-name gensyms.
16179 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
16181 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
16182 to avoid potential buffer overrun.
16184 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
16185 if X resource line is longer than 512 bytes.
16187 * xfns.c (x_window): Make sprintf buffer a bit bigger
16188 to avoid potential buffer overrun.
16190 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
16192 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
16194 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16196 Integer overflow fixes for scrolling, etc.
16197 Without these, Emacs silently mishandles large integers sometimes.
16198 For example, "C-u 4294967297 M-x recenter" was treated as if
16199 it were "C-u 1 M-x recenter" on a typical 64-bit host.
16201 * xdisp.c (try_window_id): Check Emacs fixnum range before
16202 converting to 'int'.
16204 * window.c (window_scroll_line_based, Frecenter):
16205 Check that an Emacs fixnum is in range before assigning it to 'int'.
16206 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
16207 values converted from Emacs fixnums.
16208 (Frecenter): Don't wrap around a line count if it is out of 'int'
16209 range; instead, treat it as an extreme value.
16210 (Fset_window_configuration, compare_window_configurations):
16211 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
16213 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
16214 that can exceed INT_MAX. Check that EMACS_INT value is in range
16215 before assigning it to the (possibly-narrower) index.
16216 (match_limit): Don't assume that a fixnum can fit in 'int'.
16218 * print.c (print_object): Use ptrdiff_t, not int, for index that can
16221 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
16222 (Fvertical_motion): Don't wrap around LINES values that don't fit
16223 in 'int'. Instead, treat them as extreme values. This is good
16224 enough for windows, which can't have more than INT_MAX lines anyway.
16226 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16228 * Require libxml/parser.h to avoid compilation warning.
16230 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
16232 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
16233 since this reportedly can destroy thread storage.
16235 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
16237 * syntax.c (find_defun_start): Update all cache variables if
16238 exiting early (Bug#9401).
16240 2011-08-30 Eli Zaretskii <eliz@gnu.org>
16242 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
16244 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
16245 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
16246 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
16248 * term.c (tty_append_glyph): New function.
16249 (produce_stretch_glyph): Static function and its prototype deleted.
16251 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
16254 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
16256 * image.c (parse_image_spec): Check for nonnegative, not for positive,
16257 when checking :margin (Bug#9390).
16258 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
16259 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
16260 so that the name doesn't mislead. All uses changed.
16262 2011-08-28 Johan Bockgård <bojohan@gnu.org>
16264 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
16267 2011-08-27 Eli Zaretskii <eliz@gnu.org>
16269 * xdisp.c (move_it_to): Don't bail out early when reaching
16270 position beyond to_charpos, if we are scanning backwards.
16271 (move_it_vertically_backward): When DY == 0, make sure we get to
16272 the first character in the line after the newline.
16274 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
16276 * ccl.c: Improve and simplify overflow checking (Bug#9196).
16277 (ccl_driver): Do not generate an out-of-range pointer.
16278 (Fccl_execute_on_string): Remove unnecessary check for
16279 integer overflow, noted by Stefan Monnier in
16280 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
16281 Remove a FIXME that didn't need fixing.
16282 Simplify the newly-introduced buffer reallocation code.
16284 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
16286 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
16288 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
16290 Integer and memory overflow issues (Bug#9196).
16292 * doc.c (get_doc_string): Rework so that
16293 get_doc_string_buffer_size is the actual buffer size, rather than
16294 being 1 less than the actual buffer size; this makes xpalloc more
16297 * image.c (x_allocate_bitmap_record, cache_image):
16298 * xselect.c (Fx_register_dnd_atom):
16299 Simplify previous changes by using xpalloc.
16301 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
16302 since either will do and ptrdiff_t is convenient with xpalloc.
16304 * charset.c (charset_table_size)
16305 (struct charset_sort_data.priority): Now ptrdiff_t.
16306 (charset_compare): Don't overflow if priorities differ greatly.
16307 (Fsort_charsets): Don't assume list length fits in int.
16308 Check for size-calculation overflow when allocating sort data.
16309 (syms_of_charset): Allocate an initial charset table that is
16310 just under 64 KiB, to avoid problems with glibc malloc and mmap.
16312 * cmds.c (internal_self_insert): Check for size-calculation overflow.
16314 * composite.h (struct composition.glyph_len): Now int, not unsigned.
16315 The actual value is always <= INT_MAX, and leaving it unsigned made
16316 overflow checking harder.
16318 * dispextern.h (struct glyph_matrix.rows_allocated)
16319 (struct face_cache.size): Now ptrdiff_t, for convenience in use
16320 with xpalloc. The values are still always <= INT_MAX.
16322 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
16324 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
16325 (SAFE_NALLOCA): New macro.
16327 * region-cache.c (struct boundary.pos, find_cache_boundary)
16328 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
16329 (set_cache_region, invalidate_region_cache)
16330 (revalidate_region_cache, know_region_cache, region_cache_forward)
16331 (region_cache_backward, pp_cache):
16332 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
16333 so that ptrdiff_t * can be passed to xpalloc.
16334 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
16335 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
16336 (pp_cache): Don't assume cache_len fits in int.
16337 * region-cache.h: Adjust extern decls to match.
16339 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
16340 EMACS_INT, since either will do, for xpalloc.
16342 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
16343 (xnmalloc, xnrealloc, xpalloc): New functions.
16345 * bidi.c (bidi_shelve_header_size): New constant.
16346 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
16347 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
16349 * bidi.c (bidi_cache_shrink):
16350 * buffer.c (overlays_at, overlays_in, record_overlay_string)
16352 Don't update size of array until after memory allocation succeeds,
16353 because xmalloc/xrealloc may not return.
16354 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16355 now that we have proper integer overflow checking.
16356 (record_overlay_string, overlay_strings): Catch overflows when
16357 calculating size of overlay_str_buf.
16359 * callproc.c (Fcall_process): Check for size overflow when
16360 calculating size of args2.
16361 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
16362 Normally we prefer signed values, but sticking with ptrdiff_t would
16363 require adding more-complicated checks.
16365 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16366 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
16367 Redo buffer-overflow calculations to avoid integer overflow.
16368 Add a FIXME comment where memory seems to be over-allocated.
16370 * character.c (Fstring): Check for size-calculation overflow.
16372 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
16373 unnecessary integer overflow. Check for size overflow.
16374 (encode_coding_object): Don't update size until xmalloc succeeds.
16376 * composite.c (get_composition_id): Check for overflow in glyph
16377 length calculations.
16379 Integer and memory overflow fixes for display code.
16380 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
16381 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
16382 (scrolling_window): Check for overflow in size calculations.
16383 (line_draw_cost, realloc_glyph_pool, add_row_entry):
16384 Don't assume glyph table len fits in int.
16385 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
16386 (row_table_size): Now ptrdiff_t, not int.
16387 (scrolling_window): Avoid overflow in size calculations.
16388 Don't update size until allocation succeeds.
16389 * fns.c (concat): Check for overflow in size calculations.
16390 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
16391 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
16392 (NEXT_ALMOST_PRIME_LIMIT): New constant.
16394 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
16395 (get_doc_string): Check for size calculation overflow.
16396 Don't update size until allocation succeeds.
16397 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
16398 EMACS_INT, where ptrdiff_t will do.
16399 (Fsubstitute_command_keys): Check for string overflow.
16401 * editfns.c (set_time_zone_rule): Don't assume environment length
16403 (message_length): Now ptrdiff_t, not int.
16404 (Fmessage_box): Don't update size until allocation succeeds.
16405 Don't assume message length fits in int.
16406 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16408 * emacs.c (main): Do not reallocate argv, since there is a null at
16409 the end that can be overwritten, and this way there's no need to
16410 worry about size-calculation overflow.
16411 (sort_args): Check for size-calculation overflow.
16413 * eval.c (init_eval_once, grow_specpdl): Don't update size until
16415 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
16417 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
16418 (x_set_scroll_bar_width, x_figure_window_size):
16419 Check for integer overflow.
16420 (x_set_alpha): Do not assume XINT fits in int.
16422 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
16423 This is for the members text_lines, text_cols, total_lines, total_cols,
16424 where the system imposes an 'int' limit.
16426 * fringe.c (Fdefine_fringe_bitmap):
16427 Don't update size until alloc works.
16429 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
16430 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
16432 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
16433 Check for size-calculation overflow.
16434 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
16435 do, as we prefer signed integers.
16436 (id_to_widget.max_size, id_to_widget.used)
16437 (xg_store_widget_in_map, xg_remove_widget_from_map)
16438 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
16439 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
16440 Use and return ptrdiff_t, not int.
16441 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
16442 * gtkutil.h: Change prototypes to match the above.
16444 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
16445 are duplicate now that they've been promoted to lisp.h.
16446 (x_allocate_bitmap_record, x_alloc_image_color)

16489 (Fset_match_data): Don't assume list lengths fit in 'int'.
16491 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
16492 for command line length. Do not attempt to address one before the
16493 beginning of an array, as that's not portable.

16523 Check for size calculation overflow.
16524 (cache_face): Treat size calculation overflows as if they were
16525 memory exhaustion (the usual treatment), rather than aborting.
16527 * xfns.c (x_encode_text, x_set_name_internal)
16528 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16529 sizes, since they can exceed INT_MAX in size. Check for size
16530 calculation overflow.
16532 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
16533 (xg_select): Check for size calculation overflow.
16534 Don't update size until alloc done.
16536 * xrdb.c (get_environ_db): Don't assume path length fits in int,
16537 as sprintf is limited to int lengths.
16539 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
16540 (X_LONG_MIN): New macros.
16541 Use them to make the following changes clearer.
16542 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16543 This change doesn't affect the value now, but it may help remind
16544 future maintainers not to raise the value too much later.
16545 (SELECTION_QUANTUM): Remove, replacing with ...
16546 (selection_quantum): ... new function, which avoids overflow.
16548 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16549 assumption that selection length fits in 'int'.

16566 Don't store size until memory allocation succeeds.
16567 (x_get_window_property): Plug memory leak on memory exhaustion.
16568 Don't double-block input; malloc is safe here. Don't assume 2**34
16569 - 4 fits in unsigned long. Add an xassert to check
16570 XGetWindowProperty overflow. Be more careful about overflow
16571 calculations, and distinguish size from memory overflow better.
16572 (receive_incremental_selection): When tracing, don't assume
16573 unsigned int is less than INT_MAX.
16574 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

16578 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16579 result parameters unless successful. Rely on cons_to_unsigned
16580 to report problems with elements; the old code wasn't right anyway.
16581 (x_check_property_data): Check for int overflow; we cannot use
16582 a wider type due to X limits.

16615 * lisp.h (hash_lookup, hash_put):
16616 * minibuf.c (Ftest_completion):
16617 Use ptrdiff_t for hash table indexes, not int (which is too
16618 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16619 32-bit --with-wide-int hosts).
16621 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16622 Add a FIXME comment about memory leaks.

16630 with outlandish widths.
16631 * character.h (sanitize_tab_width): Rename from sanitize_width,
16632 now that we have two such functions. All uses changed.

16650 * xterm.c: Don't go over XClientMessageEvent limit.
16651 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16652 (x_send_scroll_bar_event): Likewise. Check that the size does not
16653 exceed limits imposed by XClientMessageEvent, as well as the usual
16654 ptrdiff_t and size_t limits.
16656 * keyboard.c: Overflow, signedness and related fixes.
16657 (make_lispy_movement): Use same integer type in forward decl
16658 that is used in the definition.
16659 (read_key_sequence, keyremap_step):
16660 Change bufsize argument back to int, undoing my 2011-03-30 change.
16661 We prefer signed types, and int is wide enough here.
16662 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16663 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16664 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16665 length, not size_t. Use ptrdiff_t for index, not int.
16666 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16667 possibility of integer overflow.

16695 Prefer int to unsigned where either will do.
16696 (tiff_handler): New function, combining the cores of the
16697 old tiff_error_handler and tiff_warning_handler.
16698 This function is rewritten to use vsnprintf and thereby avoid
16699 stack buffer overflows. It uses only the features of vsnprintf
16700 that are common to both POSIX and native Microsoft.
16701 (tiff_error_handler, tiff_warning_handler): Use it.
16702 (tiff_load, gif_load, imagemagick_load_image):
16703 Don't assume :index value fits in 'int'.
16704 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16705 (imagemagick_load_image): Check that crop parameters fit into
16706 the integer types that MagickCropImage accepts. Don't assume
16707 Vimagemagick_render_type has a nonnegative value. Don't assume
16708 size_t fits in 'long'.
16709 (gs_load): Use printmax_t to print the widest integers possible.

16723 (handle_single_display_spec): If the display spec is of the form
16724 `(space ...)', and specifies display in the text area, return 2
16726 (try_cursor_movement): Check for the need to scroll more
16727 accurately, and prefer exact match for point under bidi.
16728 Don't advance `row' beyond the last row of the window.

16746 buffers, return left-to-right.
16747 (set_cursor_from_row): Consider candidate row a win if its glyph

16749 positioning on the newline at EOL of R2L text within L2R
16750 paragraph, and vice versa.
16751 (try_cursor_movement): Check continued rows, in addition to
16752 continuation rows. Fixes unwarranted scroll when point enters a
16753 continued line of R2L text within an L2R paragraph, or vice versa.
16754 (cursor_row_p): Consider the case of point being equal to
16755 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

16784 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16785 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16786 candidate is selected by the mouse, and that candidate has a
16787 composed character under the mouse.
16789 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16790 coordinates reported by pos-visible-in-window-p for a composed
16791 character in column zero.

16799 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
16800 consider it a hit if to_charpos is anywhere in the range of the
16801 composed buffer positions.
16803 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16805 * image.c (gif_load): Don't assume that each subimage has the same
16806 dimensions as the base image. Handle disposal method that is
16807 "undefined" by the gif spec (Bug#9335).
16809 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
16811 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

16821 a composition, take its buffer position from IT->cmp_it.charpos.
16822 Fixes cursor positioning at the beginning of a line that begins
16823 with a composed character.
16825 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16827 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16828 character bidirectional type, use STRONG_L instead. Fixes crashes
16829 in a buffer produced by `describe-categories'.
16831 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16832 members before the level stack, so they would be saved and
16833 restored when copying iterator state. Fixes incorrect reordering
16834 around TABs covered by display properties.

16893 bidi_ignore_explicit_marks_for_paragraph_level.
16894 (bidi_initialize): Use uniprop_table instead of including
16895 biditype.h and bidimirror.h.
16897 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
16898 coordinates of the iterator when restoring from ppos_it.
16901 2011-08-14 Kenichi Handa <handa@m17n.org>
16903 * process.c (create_process): Call setup_process_coding_systems
16904 after the pid of the process is set to -1 (Bug#8162).
16906 2011-08-14 Eli Zaretskii <eliz@gnu.org>
16908 * xdisp.c (move_it_in_display_line_to): Don't invoke
16909 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16910 ppos_it. Fixes vertical cursor motion when line beginning is
16911 covered by an image. (Bug#9296)
16913 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
16915 * nsterm.h (ns_run_ascript): Declare.
16916 (NSAPP_DATA2_RUNASSCRIPT): Define.
16918 * nsfns.m (as_script, as_result, as_status): New static variables.
16919 (ns_run_ascript): New function.
16920 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
16921 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
16922 the event loop. Get status from as_status (Bug#7276).
16924 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16925 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16926 the event loop (Bug#7276).
16928 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
16930 * gnutls.c (QCgnutls_bootprop_priority)
16931 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
16932 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
16933 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
16934 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
16935 (QCgnutls_bootprop_verify_hostname_error)
16936 (QCgnutls_bootprop_callbacks_verify): Rename from
16937 Qgnutls_bootprop_..., all uses changed.
16939 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
16942 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
16944 * xfaces.c (Qframe_set_background_mode): Now static.
16945 * dispextern.h (Qframe_set_background_mode): Remove decl.
16947 * process.c (Fnetwork_interface_info): Declare local only if needed.
16949 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
16951 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
16952 (Fnetwork_interface_list): Allocate in increments of bytes instead
16953 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16954 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16956 (struct ifflag_def): notrailers is smart on OSX.
16957 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16958 Get hardware address with getifaddrs if available.
16960 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16962 * xdisp.c (iterate_out_of_display_property): xassert that
16963 IT->position is set to within IT->object's boundaries. Break from
16964 the loop as soon as EOB is reached; avoids infloops in redisplay
16965 when IT->position is set up wrongly due to some bug.
16966 Set IT->current to match the bidi iterator unconditionally.
16967 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16968 entry. Force push_it to save on the stack the current
16969 buffer/string position, to be restored by pop_it. Fix flags in
16970 the iterator structure wrt the object coming from a display
16971 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16972 properties. (Bug#9284)
16974 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16976 * fontset.c (fontset_get_font_group): Add proper type checks.
16979 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16981 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
16982 and LC_VERSION_MIN_MACOSX.
16983 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
16984 (dump_it) [LC_FUNCTION_STARTS]: Use it.
16986 2011-08-08 Eli Zaretskii <eliz@gnu.org>
16988 * xdisp.c (forward_to_next_line_start): Allow to use the
16989 no-display-properties-and-no-overlays under bidi display.
16990 Set disp_pos in the bidi iterator to avoid searches for display
16991 properties and overlays.
16993 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16995 * editfns.c (Fset_time_zone_rule): Document relationship with the
16998 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
16999 the font entity extracted from the cache (Bug#8109).
17001 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
17003 * composite.c (autocmp_chars): Don't reset point. That is done by
17004 restore_point_unwind (Bug#5984).
17006 2011-08-07 Juri Linkov <juri@jurta.org>
17008 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
17009 to show the arg `TIME' instead of `TIMEVAL'.
17011 2011-08-06 Eli Zaretskii <eliz@gnu.org>
17013 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
17014 display property strides EOL and includes a newline, as in
17015 longlines-mode. (Bug#9254)
17016 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
17017 word-wrap under bidirectional display. (Bug#9224)
17019 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
17020 is non-zero, even if the data buffer is NULL. Fixes a crash in
17021 vertical-motion with longlines-mode. (Bug#9254)
17023 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17025 * bidi.c <bidi_cache_total_alloc>: Now static.
17026 (bidi_initialize): Initialize bidi_cache_total_alloc.
17028 * xdisp.c (display_line): Release buffer allocated for shelved bidi
17031 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
17032 amount allocated this far in `bidi_cache_total_alloc'.
17033 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
17034 non-zero, only free the data buffer without restoring the cache
17035 contents. All callers changed.
17037 * dispextern.h (bidi_unshelve_cache): Update prototype.
17039 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
17040 (move_it_in_display_line, move_it_to)
17041 (move_it_vertically_backward, move_it_by_lines): Replace the call
17042 to xfree to an equivalent call to bidi_unshelve_cache.
17043 (move_it_in_display_line_to): Fix logic of returning
17044 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
17046 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17048 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
17049 came from a string character with a `cursor' property. (Bug#9229)
17051 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17053 * Makefile.in (LIB_PTHREAD): New variable.
17054 (LIBES): Add LIB_PTHREAD (Bug#9216).
17056 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
17057 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
17059 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
17061 * regex.c (re_iswctype): Remove some redundant boolean conversions.
17063 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17065 * xterm.c (x_find_topmost_parent): New function.
17066 (x_set_frame_alpha): Find topmost parent window with
17067 x_find_topmost_parent and set the property there also (bug#9181).
17068 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
17070 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
17072 * callproc.c (Fcall_process): Avoid vfork clobbering
17073 the local vars buffer, coding_systems, current_dir.
17075 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
17077 * keymap.c (Fmake_composed_keymap): Move to subr.el.
17079 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
17081 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
17082 so that it is not optimized away.
17084 * xdisp.c (compute_display_string_pos): Remove unused local.
17086 2011-08-02 Eli Zaretskii <eliz@gnu.org>
17088 Fix slow cursor motion and scrolling in large buffers with
17089 selective display, like Org Mode buffers. (Bug#9218)
17091 * dispextern.h (struct bidi_it): New member disp_prop_p.
17093 * xdisp.c: Remove one-slot cache of display string positions.
17094 (compute_display_string_pos): Accept an additional argument
17095 DISP_PROP_P; callers changed. Scan at most 5K characters forward
17096 for a display string or property. If found, set DISP_PROP_P
17099 * bidi.c (bidi_fetch_char): Accept an additional argument
17100 DISP_PROP_P, and pass it to compute_display_string_pos.
17101 Only handle text covered by a display string if DISP_PROP_P is returned
17102 non-zero. All callers of bidi_fetch_char changed.
17104 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
17106 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
17108 2010-12-03 Don March <don@ohspite.net>
17110 * keymap.c (Fdefine_key): Fix non-prefix key error message when
17111 last character M-[char] is translated to ESC [char] (bug#7541).
17113 2011-08-02 Kenichi Handa <handa@m17n.org>
17115 * lisp.h (uniprop_table): Extern it.
17117 * chartab.c (uniprop_table): Make it non-static.
17119 2011-08-01 Eli Zaretskii <eliz@gnu.org>
17121 * xdisp.c (forward_to_next_line_start): Accept additional argument
17122 BIDI_IT_PREV, and store into it the state of the bidi iterator had
17124 (reseat_at_next_visible_line_start): Use the bidi iterator state
17125 returned by forward_to_next_line_start to restore the state of
17126 it->bidi_it after backing up to previous newline. (Bug#9212)
17128 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
17130 * regex.c (re_comp): Protoize.
17131 (re_exec): Fix return type.
17132 (regexec): Fix type of `ret'. (Bug#9203)
17134 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17136 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
17137 This is needed if max-image-size is a floating-point number.
17139 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17141 * print.c (print_object): Print empty symbol as ##.
17143 * lread.c (read1): Read ## as empty symbol.
17145 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17147 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
17148 setting frame foreground color (Bug#9175).
17149 (x_set_background_color): Likewise.
17151 * nsmenu.m (-setText): Size tooltip dimensions precisely to
17152 contents (Bug#9176).
17153 (EmacsTooltip -init): Remove bezels and add shadows to
17156 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
17157 or scroll bar (Bug#8470).
17159 * nsfont.m (nsfont_open): Remove assignment to voffset and
17160 unnecessary vars hshink, expand, hd, full_height, min_height.
17161 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
17163 * nsterm.h (nsfont_info): Remove voffset field.
17165 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17167 Implement strike-through and overline on NextStep (Bug#8863).
17169 * nsfont.m (nsfont_open): Use underline position provided by font,
17170 instead of hard-coded value of 2.
17171 (nsfont_draw): Call ns_draw_text_decoration instead.
17173 * nsterm.h: Add declaration for ns_draw_text_decoration.
17175 * nsterm.m (ns_draw_text_decoration): New function for drawing
17176 underline, overline, and strike-through.
17177 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
17178 ns_draw_text_decoration. Change treatment of cursor drawing to
17179 accommodate underlining, etc.
17181 2011-07-28 Eli Zaretskii <eliz@gnu.org>
17183 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
17186 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17188 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
17189 Without this fix, if a signal arrives just after memory fills up,
17190 'malloc' might be invoked reentrantly.
17192 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
17193 In other words, assume that every image size is allowed, on non-X
17194 hosts. This assumption is probably wrong, but it lets Emacs compile.
17196 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17198 * regex.c (re_iswctype): Convert return values to boolean.
17200 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
17202 * xdisp.c (compute_display_string_pos): Don't use cached display
17203 string position if the buffer had its restriction changed.
17206 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17208 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17210 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17212 Integer signedness and overflow and related fixes. (Bug#9079)
17214 * bidi.c: Integer size and overflow fixes.
17215 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
17216 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
17217 (bidi_cache_find_level_change, bidi_cache_ensure_space)
17218 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
17219 (bidi_find_other_level_edge):
17220 Use ptrdiff_t instead of EMACS_INT where either will do.
17221 This works better on 32-bit hosts configured --with-wide-int.
17222 (bidi_cache_ensure_space): Check for size-calculation overflow.
17223 Use % rather than repeated addition, for better worst-case speed.
17224 Don't set bidi_cache_size until after xrealloc returns, because it
17226 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
17227 (bidi_cache_ensure_space): Also check that the bidi cache size
17228 does not exceed that of the largest Lisp string or buffer. See Eli
17229 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
17231 * alloc.c (__malloc_size_t): Remove.
17232 All uses replaced by size_t. See Andreas Schwab's note
17233 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
17235 * image.c: Improve checking for integer overflow.
17236 (check_image_size): Assume that f is nonnull, since
17237 it is always nonnull in practice. This is one less thing to
17238 worry about when checking for integer overflow later.
17239 (x_check_image_size): New function, which checks for integer
17240 overflow issues inside X.
17241 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
17242 This removes the need for a memory_full check.
17243 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
17244 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
17245 (xbm_read_bitmap_data): Change locals back to 'int', since
17246 their values must fit in 'int'.
17247 (xpm_load_image, png_load, tiff_load):
17248 Invoke x_create_x_image_and_pixmap earlier,
17249 to avoid much needless work if the image is too large.
17250 (tiff_load): Treat overly large images as if
17251 x_create_x_image_and_pixmap failed, not as malloc failures.
17252 (gs_load): Use x_check_image_size.
17254 * gtkutil.c: Omit integer casts.
17255 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
17256 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
17258 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
17260 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
17261 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
17262 would wrongly return t on a 64-bit host.
17264 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
17265 The plain *_OVERFLOW macros run afoul of GCC bug 49705
17266 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
17267 and therefore cause GCC to emit a bogus diagnostic in some cases.
17269 * image.c: Integer signedness and overflow and related fixes.
17270 This is not an exhaustive set of fixes, but it's time to
17271 record what I've got.
17272 (lookup_pixel_color, check_image_size): Remove redundant decls.
17273 (check_image_size): Don't assume that arbitrary EMACS_INT values
17274 fit in 'int', or that arbitrary 'double' values fit in 'int'.
17275 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
17276 (tiff_load, imagemagick_load_image):
17277 Check for overflow in size calculations.
17278 (x_create_x_image_and_pixmap): Remove unnecessary test for
17279 xmalloc returning NULL; that can't happen.
17280 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
17281 (xpm_color_bucket): Use better integer hashing function.
17282 (xpm_cache_color): Don't possibly over-allocate memory.
17283 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
17284 (gif_memory_source):
17285 Use ptrdiff_t, not int or size_t, to record sizes.
17286 (png_load): Don't assume values greater than 2**31 fit in 'int'.
17287 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
17288 either works, as we prefer signed integers.
17289 (tiff_read_from_memory, tiff_write_from_memory):
17290 Return tsize_t, not size_t, since that's what the TIFF API wants.
17291 (tiff_read_from_memory): Don't fail simply because the read would
17292 go past EOF; instead, return a short read.
17293 (tiff_load): Omit no-longer-needed casts.
17294 (Fimagemagick_types): Don't assume size fits into 'int'.
17296 Improve hashing quality when configured --with-wide-int.
17297 * fns.c (hash_string): New function, taken from sxhash_string.
17298 Do not discard information about ASCII character case; this
17299 discarding is no longer needed.
17300 (sxhash-string): Use it. Change sig to match it. Caller changed.
17301 * lisp.h: Declare it.
17302 * lread.c (hash_string): Remove, since we now use fns.c's version.
17303 The fns.c version returns a wider integer if --with-wide-int is
17304 specified, so this should help the quality of the hashing a bit.
17306 * emacs.c: Integer overflow minor fix.
17307 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
17308 Define only if GNU_LINUX.
17309 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
17311 * dispnew.c: Integer signedness and overflow fixes.
17312 Remove unnecessary forward decls, that were a maintenance hassle.
17313 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
17315 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
17316 (scrolling_window): Use ptrdiff_t, not int, for byte count.
17317 (prepare_desired_row, line_draw_cost):
17318 Use int, not unsigned, where either works.
17319 (save_current_matrix, restore_current_matrix):
17320 Use ptrdiff_t, not size_t, where either works.
17321 (init_display): Check for overflow more accurately, and without
17322 relying on undefined behavior.
17324 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
17325 Remove, replacing with the new symbols in lisp.h. All uses changed.
17326 * fileio.c (make_temp_name):
17327 * filelock.c (lock_file_1, lock_file):
17328 * xdisp.c (message_dolog):
17329 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
17330 Use pMd etc. instead.
17331 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
17332 replacing the pWIDE etc. symbols removed from editfns.c.
17334 * keyboard.h (num_input_events): Now uintmax_t.
17335 This is (very slightly) less likely to mess up due to wraparound.
17338 * buffer.c: Integer signedness fixes.
17339 (alloc_buffer_text, enlarge_buffer_text):
17340 Use ptrdiff_t rather than size_t when either will do, as we prefer
17343 * alloc.c: Integer signedness and overflow fixes.
17344 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
17345 (__malloc_size_t): Default to size_t, not to int.
17346 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
17347 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17348 Prefer ptrdiff_t to size_t when either would do, as we prefer
17350 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17351 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17352 Now const. Initialize with values that are in range even if char
17354 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17355 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17356 These functions do the right thing with sizes > 2**32.
17357 (check_depth): Now ptrdiff_t, not int.
17358 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17359 Adjust to new way of storing sizes. Check for size overflow bugs
17361 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17362 slightly wrong anyway, as it missed one instance of
17363 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17364 (refill_memory_reserve): Omit needless cast to size_t.
17365 (mark_object_loop_halt): Mark as externally visible.
17367 * xselect.c: Integer signedness and overflow fixes.
17368 (Fx_register_dnd_atom, x_handle_dnd_message):
17369 Use ptrdiff_t, not size_t, since we prefer signed.
17370 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17371 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17372 x_dnd_atoms_size and x_dnd_atoms_length.
17374 * doprnt.c: Prefer signed to unsigned when either works.
17376 * doprnt.c (doprnt):
17378 * xdisp.c (vmessage):
17379 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17380 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17381 prefer signed arithmetic to avoid comparison confusion.
17382 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17383 but is a bit tricky.
17385 Assume freestanding C89 headers, string.h, stdlib.h.
17386 * data.c, doprnt.c, floatfns.c, print.c:
17387 Include float.h unconditionally.
17388 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17389 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17390 * regex.c: Likewise for stddef.h, string.h.
17391 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17392 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17393 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17394 (STDC_HEADERS): Remove obsolete defines.
17395 * sysdep.c: Include limits.h unconditionally.
17397 Assume support for memcmp, memcpy, memmove, memset.
17398 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17399 * regex.c (memcmp, memcpy):
17400 Remove; we assume C89 now.
17402 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17403 (__malloc_safe_bcopy): Remove; no longer needed.
17405 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17406 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17407 well either way, and we prefer signed to unsigned.
17409 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17411 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17412 closes the connection while we're reading (bug#9182).
17414 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17416 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17417 are specified (Bug#9168).
17419 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17421 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17422 Found by GCC static checking and --with-wide-int on a 32-bit host.
17424 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17426 * xdisp.c (compute_display_string_pos): Fix logic of caching
17427 previous display string position. Initialize cached_prev_pos to
17428 -1. Fixes slow-down at the beginning of a buffer.
17430 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17432 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17433 for attrs[LFACE_FONTSET_INDEX].
17435 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17437 * xml.c (parse_region): Remove unused local
17438 that was recently introduced.
17440 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17442 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17443 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17445 * xdisp.c (move_it_in_display_line_to): Record the best matching
17446 position for TO_CHARPOS while scanning the line, and restore it on
17447 exit if none of the characters scanned was an exact match.
17448 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17449 when exact match is impossible due to invisible text, and the
17450 lines are truncated.
17452 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17454 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17457 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17459 Fix a significant slow-down of cursor motion with C-n, C-p,
17460 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17461 auto-repeat under bidi redisplay in fontified buffers.
17462 * xdisp.c (compute_stop_pos_backwards): New function.
17463 (next_element_from_buffer): Call compute_stop_pos_backwards to
17464 find a suitable prev_stop when we find ourselves before
17466 (reseat): Don't look for prev_stop, as that could mean a very long
17468 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17469 <cached_disp_overlay_modiff>: Cache for last found display string
17471 (compute_display_string_pos): Return the cached position if asked
17472 about the same buffer in the same area of character positions, and
17473 the buffer wasn't changed since the time the display string
17474 position was cached.
17476 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17478 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17479 is an integer, which is important for empty lines. (Bug#9149)
17481 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17483 * frame.c (Fmodify_frame_parameters): In tty case, update the
17484 default face if necessary (Bug#4238).
17486 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17488 * editfns.c (Fstring_to_char): No need to explain what a character
17489 is in the docstring (Bug#6576).
17491 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17493 * xml.c (parse_region): Make sure we always return a tree.
17495 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17497 * xml.c (parse_region): If a document contains only comments,
17500 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17502 * xml.c (make_dom): Return comments, too.
17504 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17507 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17508 and the surrounding thread.
17509 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17510 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17511 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17513 * s/openbsd.h (BROKEN_SIGIO): Define.
17514 * unexelf.c (unexec) [__OpenBSD__]:
17515 Don't update the .mdebug section of the Alpha COFF symbol table.
17517 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17519 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17522 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17524 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17525 This fixes some race conditions on the permissions of any newly
17528 * alloc.c (valid_pointer_p): Use pipe, not open.
17529 This fixes some permissions issues when debugging.
17531 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17532 If fchown fails to set both uid and gid, try to set just gid,
17533 as that is sometimes allowed. Adjust the file's mode to eliminate
17534 setuid or setgid bits that are inappropriate if fchown fails.
17536 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17538 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
17539 to compare Lisp_Objects.
17540 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
17541 global_gnutls_log_level, don't mistake it for a Lisp_Object.
17542 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
17544 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17546 * lread.c (read_integer): Unread even EOF character.
17547 (read1): Likewise. Properly record start position of symbol.
17549 * lread.c (read1): Read `#:' as empty uninterned symbol if no
17550 symbol character follows.
17552 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17554 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17555 This works around a problem with the previous change to Fcopy_file.
17556 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17557 and without this change, GCC might complain about discarding
17558 fchown's return value.
17560 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17562 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17564 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17566 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17568 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17570 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17571 it's used from the C level.
17573 * process.c: Use the same condition for POLL_FOR_INPUT in both
17574 keyboard.c and process.c (bug#1858).
17576 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17578 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17579 (Fgnutls_boot): Use it.
17581 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17583 * doc.c (Fsubstitute_command_keys): Revert last change.
17585 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17587 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17588 quotes the next character, and doesn't affect other longer
17589 sequences (bug#8935).
17591 * lread.c (syms_of_lread): Clarify that is isn't only
17592 `eval-buffer' and `eval-defun' that's affected by
17593 `lexical-binding' (bug#8460).
17595 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17597 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17598 bidi redisplay when a line includes both an image and is truncated.
17600 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17602 Fix minor problems found by static checking.
17603 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17604 (elsz): Now a signed constant, not a size_t var. We prefer signed
17605 types to unsigned, to avoid integer comparison confusion. Without
17606 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17607 "cannot optimize loop, the loop counter may overflow", a symptom
17609 * indent.c (Fvertical_motion): Mark locals as initialized.
17610 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17612 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
17614 * search.c (Fre_search_backward): Mention `case-fold-search' in
17615 all the re_search_* functions (bug#8138).
17617 * keyboard.c (Fopen_dribble_file): Document when the file is

17627 (compute_display_string_end): Accept additional argument STRING.
17628 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
17629 (reseat_to_string): Initialize bidi_it->string.s and
17630 bidi_it->string.schars.
17631 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
17632 NULL (avoids a crash in bidi_paragraph_init).
17633 Initialize itb.string.lstring.
17634 (init_iterator): Call bidi_init_it only of a valid
17635 buffer position was specified. Initialize paragraph_embedding to
17637 (reseat_to_string): Initialize the bidi iterator.
17638 (display_string): If we need to ignore text properties of
17639 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17640 original value of -1 will not work with bidi.)
17641 (compute_display_string_pos): First arg is now struct
17642 `text_pos *'; all callers changed. Support display properties on
17644 (compute_display_string_end): Support display properties on Lisp
17646 (init_iterator, reseat_1, reseat_to_string): Initialize the
17647 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
17648 when iterating on a string not from display properties).
17649 (compute_display_string_pos, compute_display_string_end):
17650 Fix calculation of the object to scan. Fixes an error when using
17652 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
17653 base_level_stop; instead, set base_level_stop to BEGV.
17654 Fixes crashes in vertical-motion.
17655 (next_element_from_buffer): Improve commentary for when
17656 the iterator is before prev_stop.
17657 (init_iterator): Initialize bidi_p from the default value of
17658 bidi-display-reordering, not from buffer-local value. Use the
17659 buffer-local value only if initializing for buffer iteration.
17660 (handle_invisible_prop): Support invisible properties on strings
17661 that are being bidi-reordered.
17662 (set_iterator_to_next): Support bidi reordering of C strings and
17664 (next_element_from_string): Support bidi reordering of Lisp
17666 (handle_stop_backwards): Support Lisp strings as well.
17667 (display_string): Support display of R2L glyph rows.
17668 Use IT_STRING_CHARPOS when displaying from a Lisp string.
17669 (init_iterator): Don't initialize it->bidi_p for strings
17671 (reseat_to_string): Initialize it->bidi_p for strings here.
17672 (next_element_from_string, next_element_from_c_string)
17673 (next_element_from_buffer): Add xassert's for correspondence
17674 between IT's object being iterated and it->bidi_it.string
17676 (face_before_or_after_it_pos): Support bidi iteration.
17677 (next_element_from_c_string): Handle the case of the first string
17678 character that is not the first one in the visual order.
17679 (get_visually_first_element): New function, refactored from common
17680 parts of next_element_from_buffer, next_element_from_string, and
17681 next_element_from_c_string.
17682 (tool_bar_lines_needed, redisplay_tool_bar)
17683 (display_menu_bar): Force left-to-right direction. Add a FIXME
17684 comment for making that be controlled by a user option.
17685 (push_it, pop_it): Save and restore the state of the
17686 bidi iterator. Save and restore the bidi_p flag.
17687 (pop_it): Iterate out of display property for string iteration as
17689 (iterate_out_of_display_property): Support iteration over strings.
17690 (handle_single_display_spec): Set up it->bidi_it for iteration
17691 over a display string, and call bidi_init_it.
17692 (handle_single_display_spec, next_overlay_string)
17693 (get_overlay_strings_1, push_display_prop): Set up the bidi
17694 iterator for displaying display or overlay strings.
17695 (forward_to_next_line_start): Don't use the shortcut if
17697 (back_to_previous_visible_line_start): If handle_display_prop
17698 pushed the iterator stack, restore the internal state of the bidi
17699 iterator by calling bidi_pop_it same number of times.
17700 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
17701 and we are bidi-iterating, don't decrement the iterator position;
17702 instead, set the first_elt flag in the bidi iterator, to produce
17704 (reseat_1): Remove redundant setting of string_from_display_prop_p.
17705 (push_display_prop): xassert that we are iterating a buffer.
17706 (push_it, pop_it): Save and restore paragraph_embedding member.
17707 (handle_single_display_spec, next_overlay_string)
17708 (get_overlay_strings_1, reseat_1, reseat_to_string)
17709 (push_display_prop): Set up the `unibyte' member of bidi_it.string
17710 correctly. Don't assume unibyte strings are not bidi-reordered.
17711 (compute_display_string_pos)
17712 (compute_display_string_end): Fix handling the case of C string.
17713 (push_it, pop_it): Save and restore from_disp_prop_p.
17714 (handle_single_display_spec, push_display_prop): Set the
17715 from_disp_prop_p flag.
17716 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
17717 (pop_it): Call iterate_out_of_display_property only if we are
17718 popping after iteration over a string that came from a display
17719 property. Fix a typo in popping stretch info. Add an assertion
17720 for verifying that the iterator position is in sync with the bidi
17722 (handle_single_display_spec, get_overlay_strings_1)
17723 (push_display_prop): Fix initialization of paragraph direction for
17724 string when that of the parent object is not yet determined.
17725 (reseat_1): Call bidi_init_it to resync the bidi
17726 iterator with IT's position. (Bug#7616)
17727 (find_row_edges): If ROW->start.pos gives position
17728 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
17729 (handle_stop, back_to_previous_visible_line_start, reseat_1):
17730 Reset the from_disp_prop_p flag.
17731 (SAVE_IT, RESTORE_IT): New macros.
17732 (pos_visible_p, face_before_or_after_it_pos)
17733 (back_to_previous_visible_line_start)
17734 (move_it_in_display_line_to, move_it_in_display_line)
17735 (move_it_to, move_it_vertically_backward, move_it_by_lines)
17736 (try_scrolling, redisplay_window, display_line): Use them when
17737 saving a temporary copy of the iterator and restoring it back.
17738 (back_to_previous_visible_line_start, reseat_1)
17739 (init_iterator): Empty the bidi cache "stack".
17740 (move_it_in_display_line_to): If iterator ended up at
17741 EOL, but we never saw any buffer positions smaller than
17742 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
17743 motion in bidi-reordered lines.
17744 (move_it_in_display_line_to): Record prev_method and prev_pos
17745 immediately before the call to set_iterator_to_next. Fixes cursor
17746 motion in bidi-reordered lines with stretch glyphs and strings
17747 displayed in margins. (Bug#8133) (Bug#8867)
17748 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
17750 (pos_visible_p): Support positions in bidi-reordered lines.
17751 Save and restore bidi cache.
17753 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
17754 (bidi_paragraph_info): Delete unused struct.
17755 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
17756 (bidi_cache_start): New variable.
17757 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
17759 (bidi_cache_fetch_state, bidi_cache_search)
17760 (bidi_cache_find_level_change, bidi_cache_iterator_state)
17761 (bidi_cache_find, bidi_peek_at_next_level)

17765 (bidi_fetch_char): Accept new argument STRING; all callers
17766 changed. Support iteration over a string. Support strings with
17767 display properties. Support unibyte strings. Fix the type of
17768 `len' according to what STRING_CHAR_AND_LENGTH expects.
17769 (bidi_paragraph_init, bidi_resolve_explicit_1)
17770 (bidi_resolve_explicit, bidi_resolve_weak)
17771 (bidi_level_of_next_char, bidi_move_to_visually_next):

17866 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
17867 The old code sometimes used this field without initializing it.
17869 * alloc.c (gc_sweep): Don't read past end of array.
17870 In theory, the old code could also have corrupted Emacs internals,
17871 though it'd be very unlikely.

18132 * alloc.c (mark_buffer):
18133 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
18134 (clone_per_buffer_values): Don't assume that
18135 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
18136 This isn't true in general, and it's particularly not true
18137 if Emacs is configured with --with-wide-int.
18138 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
18139 New macros, used in the buffer.c change.

18175 Random fixes. E.g., (random) never returned negative values.
18176 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
18177 subseconds part to the entropy, as that's a bit more random.
18178 Prefer signed to unsigned, since the signedness doesn't matter and
18179 in general we prefer signed. When given a limit, use a
18180 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
18181 latter isn't right if USE_2_TAGS_FOR_INTS.
18182 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
18183 not 0..VALMASK. Don't discard "excess" bits that random () returns.

18193 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
18195 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
18196 This is more efficient than Ffile_directory_p and avoids a minor race.
18198 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
18200 * buffer.c (Foverlay_put): Say what the return value is
18203 * fileio.c (barf_or_query_if_file_exists): Check first if the file
18204 is a directory before asking whether to use the file name
18206 (barf_or_query_if_file_exists): Make the "File is a directory"
18207 error be more correct.
18209 * fns.c (Frequire): Remove the mention of the .gz files, since
18210 that's installation-specific, but keep the mention of
18211 `get-load-suffixes'.
18213 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>

18328 * eval.c (struct backtrace): Simplify and port the data structure.
18329 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
18330 signed bit field, as this assumption is not portable and it makes
18331 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
18332 "char debug_on_exit : 1" as this is not portable either; instead,
18333 use the portable "unsigned int debug_on_exit : 1". Remove unused
18334 member evalargs. Remove obsolete comments about cc bombing out.

18524 (read1): Check for integer overflow in radices, and in
18525 read-circle numbers.
18526 (read_escape): Avoid int overflow.
18527 (Fload, openp, read_buffer_size, read1)
18528 (substitute_object_recurse, read_vector, read_list, map_obarray):

18569 on undefined behavior with wrong number of arguments.
18570 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18571 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18572 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18573 since we're not interested in debugging glyphs with old libraries.
18574 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18575 GCC 4.6.0's static checking.

18617 (x_session_initialize): Do not assume string length fits in int.
18619 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.

18657 Don't assume integer property fits in fixnum.
18658 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
18660 * filelock.c: Fix some buffer overrun and integer overflow issues.
18661 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18662 Reformulate so as not to need the command string.
18663 Invoke gzip -cd rather than gunzip, as it's more portable.
18664 (lock_info_type, lock_file_1, lock_file):
18665 Don't assume pid_t and time_t fit in unsigned long.
18666 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18667 (current_lock_owner): Prefer signed type for sizes.
18668 Use memcpy, not strncpy, where memcpy is what is really wanted.
18669 Don't assume (via atoi) that time_t and pid_t fit in int.
18670 Check for time_t and/or pid_t out of range, e.g., via a network share.
18671 Don't alloca where an auto var works fine.
18673 * fileio.c: Fix some integer overflow issues.
18674 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18675 Don't assume string length fits in int.
18676 (directory_file_name): Don't assume string length fits in long.
18677 (make_temp_name): Don't assume pid fits in int, or that its print
18678 length is less than 20.
18680 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
18682 * coding.c (make_subsidiaries): Don't assume string length fits in int.
18684 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
18686 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
18687 We prefer signed integers, even for size calculations.
18689 * emacs.c: Don't assume string length fits in 'int'.
18690 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
18691 (main): Don't invoke strlen when not needed.
18693 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
18694 (XD_DEBUG_MESSAGE): Don't waste a byte.
18696 * callproc.c (getenv_internal_1, getenv_internal)
18697 (Fgetenv_internal):
18698 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18700 * lread.c (invalid_syntax): Omit length argument.
18701 All uses changed. This doesn't fix a bug, but it simplifies the
18702 code away from its former Hollerith-constant appearance, and it's
18703 one less 'int' to worry about when looking at integer-overflow issues.
18704 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18706 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18707 This didn't break anything, but it didn't help either.
18708 It's confusing to put a bogus integer in a place where the actual
18709 value does not matter.
18710 (LIST_END_P): Remove unused macro and its bogus comment.
18711 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18713 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18714 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18716 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18717 We prefer signed types, and the value cannot exceed the EMACS_INT
18718 range anyway (because otherwise the length would not be representable).
18719 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18720 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18721 This avoids a GCC warning when WIDE_EMACS_INT.
18723 * indent.c (sane_tab_width): New function.
18724 (current_column, scan_for_column, Findent_to, position_indentation)
18725 (compute_motion): Use it. This is just for clarity.
18726 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18728 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
18730 * lisp.h (lint_assume): New macro.
18731 * composite.c (composition_gstring_put_cache):
18732 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18734 * editfns.c, insdel.c:
18735 Omit unnecessary forward decls, to simplify future changes.
18737 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18739 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18741 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18742 Use much-faster test for byte-length change.
18743 Don't assume string byte-length fits in 'int'.
18744 Check that character arg fits in 'int'.
18745 (mapcar1): Declare byte as byte, for clarity.
18747 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18749 * fns.c (concat): Catch string overflow earlier.
18750 Do not rely on integer wraparound.
18752 * dispextern.h (struct it.overlay_strings_charpos)
18753 (struct it.selective): Now EMACS_INT, not int.
18754 * xdisp.c (forward_to_next_line_start)
18755 (back_to_previous_visible_line_start)
18756 (reseat_at_next_visible_line_start, next_element_from_buffer):
18757 Don't arbitrarily truncate the value of 'selective' to int.
18759 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18761 * composite.c: Don't truncate sizes to 'int'.
18762 (composition_gstring_p, composition_reseat_it)
18763 (composition_adjust_point): Use EMACS_INT, not int.
18764 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18765 not EMACS_UINT, for indexes.
18767 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18769 * buffer.c: Include <verify.h>.
18770 (struct sortvec.priority, struct sortstr.priority):
18771 Now EMACS_INT, not int.
18772 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18773 (struct sortstr.size, record_overlay_string)
18774 (struct sortstrlist.size, struct sortlist.used):
18775 Don't truncate size to int.
18776 (record_overlay_string): Check for size-calculation overflow.
18777 (init_buffer_once): Check at compile-time, not run-time.
18779 2011-06-22 Jim Meyering <meyering@redhat.com>
18781 Don't leak an XBM-image-sized buffer
18782 * image.c (xbm_load): Free the image buffer after using it.
18784 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18787 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18788 that Sun C diagnosed.
18789 * fns.c (secure_hash): Fix pointer signedness issue.
18790 * intervals.c (static_offset_intervals): New function.
18791 (offset_intervals): Use it.
18793 2011-06-21 Leo Liu <sdl.web@gmail.com>
18796 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18799 * fns.c (secure_hash): Rename from crypto_hash_function and change
18800 the first arg to accept symbols.
18801 (Fsecure_hash): New primitive.
18802 (syms_of_fns): New symbols.
18804 2011-06-20 Deniz Dogan <deniz@dogan.se>
18806 * process.c (Fset_process_buffer): Clarify return value in
18809 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18811 * dispnew.c (add_window_display_history): Use BVAR.
18813 * xdisp.c (debug_method_add): Use BVAR.
18814 (check_window_end, dump_glyph_matrix, dump_glyph)
18815 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18817 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18820 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18821 check till after the cache is created in init_frame_faces.
18823 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18825 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18827 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18829 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18830 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18831 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18833 Improve buffer-overflow checking (Bug#8873).
18834 * fileio.c (Finsert_file_contents):
18835 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18836 Remove the old (too-loose) buffer overflow checks.
18837 They weren't needed, since make_gap checks for buffer overflow.
18838 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18839 The old code merely checked for Emacs fixnum overflow, and relied
18840 on undefined (wraparound) behavior. The new code avoids undefined
18841 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18843 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18844 Tune. Don't use wider integers than needed. Don't use alloca.
18845 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18847 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18849 * insdel.c, lisp.h (buffer_overflow): New function.
18850 (insert_from_buffer_1, replace_range, replace_range_2):
18851 * insdel.c (make_gap_larger):
18852 * editfns.c (Finsert_char):
18853 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18855 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18857 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18859 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18861 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18862 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18864 * fileio.c: Don't assume EMACS_INT fits in off_t.
18865 (emacs_lseek): New static function.
18866 (Finsert_file_contents, Fwrite_region): Use it.
18867 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18869 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18871 * fns.c: Don't overflow int when computing a list length.
18872 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18873 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18874 truncation on 64-bit hosts. Check for QUIT every
18875 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18876 faster and is responsive enough.
18877 (Flength): Report an error instead of overflowing an integer.
18878 (Fsafe_length): Return a float if the value is not representable
18879 as a fixnum. This shouldn't happen except in contrived situations.
18880 (Fnthcdr, Fsort): Don't assume list length fits in int.
18881 (Fcopy_sequence): Don't assume vector length fits in int.
18883 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18884 (header_size, word_size): New constants.
18885 (allocate_vectorlike): Don't check size overflow here.
18886 (allocate_vector): Check it here instead, since this is the only
18887 caller of allocate_vectorlike that could cause overflow.
18888 Check that the new vector's length is representable as a fixnum.
18890 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18891 The previous code was bogus. For example, next_almost_prime (32)
18892 returned 39, which is undesirable as it is a multiple of 3; and
18893 next_almost_prime (24) returned 25, which is a multiple of 5 so
18894 why was the code bothering to check for multiples of 7?
18896 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18898 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18900 Variadic C functions now count arguments with ptrdiff_t.
18901 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18902 Back then I didn't know that the Emacs coding style prefers signed int.
18903 Also, in the meantime I found a few more instances where arguments
18904 were being counted with int, which may truncate counts on 64-bit
18905 machines, or EMACS_INT, which may be unnecessarily wide.
18906 * lisp.h (struct Lisp_Subr.function.aMANY)
18907 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18908 Arg counts are now ptrdiff_t, not size_t.
18909 All variadic functions and their callers changed accordingly.
18910 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18911 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18912 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18913 * callint.c (Fcall_interactively): Check arg count for overflow,
18914 to avoid potential buffer overrun. Use signed char, not 'int',
18915 for 'varies' array, so that we needn't bother to check its size
18916 calculation for overflow.
18917 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18918 * eval.c (apply_lambda):
18919 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18920 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18921 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18923 * callint.c (Fcall_interactively): Don't use index var as event count.
18925 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18926 * mem-limits.h (SIZE): Remove; no longer used.
18928 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18930 Remove unnecessary casts.
18931 * xterm.c (x_term_init):
18932 * xfns.c (x_set_border_pixel):
18933 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18934 These aren't needed now that we assume ANSI C.
18936 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18937 It's more likely to cause problems (due to unsigned overflow)
18940 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18942 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18944 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18946 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18948 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18950 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18952 GLYPH_CODE_FACE returns EMACS_INT, not int.
18953 * dispextern.h (merge_faces):
18954 * xfaces.c (merge_faces):
18955 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18956 Don't assume EMACS_INT fits in int.
18958 * character.h (CHAR_VALID_P): Remove unused parameter.
18959 * fontset.c, lisp.h, xdisp.c: All uses changed.
18961 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18963 * fns.c (concat): Minor tuning based on overflow analysis.
18964 This doesn't fix any bugs. Use int to hold character, instead
18965 of constantly refetching from Emacs object. Use XFASTINT, not
18966 XINT, for value known to be a character. Don't bother comparing
18967 a single byte to 0400, as it's always less.
18969 * floatfns.c (Fexpt):
18970 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18972 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18975 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18977 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18978 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18979 incorrectly succeed when S was a string, because 4294967386 was
18980 truncated before it was used.
18982 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18983 Otherwise, an out-of-range integer could cause undefined behavior
18986 * composite.c: Use int, not EMACS_INT, for characters.
18987 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18988 EMACS_INT, for values that are known to be in character range.
18989 This doesn't fix any bugs but is the usual style inside Emacs and
18990 may generate better code on 32-bit machines.
18992 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18993 This is for reasons similar to the recent CHAR_STRING fix.
18994 * charset.c (Fencode_char): Check that character arg is actually
18995 a character. Pass an int to ENCODE_CHAR.
18996 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18997 wider than 'int', as a compile-time check to prevent future regressions
19000 * character.c (char_string): Remove unnecessary casts.
19002 Make sure a 64-bit char is never passed to CHAR_STRING.
19003 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
19004 by silently ignoring the top 32 bits, allowing some values
19005 that were far too large to be valid characters.
19006 * character.h: Include <verify.h>.
19007 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
19008 arguments are no wider than unsigned, as a compile-time check
19009 to prevent future regressions in this area.
19011 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
19012 (Fsubst_char_in_region):
19014 * xdisp.c (decode_mode_spec_coding):
19015 Adjust to CHAR_STRING's new requirement.
19016 * editfns.c (Finsert_char, Fsubst_char_in_region):
19017 * fns.c (concat): Check that character args are actually
19018 characters. Without this test, these functions did the wrong
19019 thing with wildly out-of-range values on 64-bit hosts.
19021 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
19022 These casts should not be needed on 32-bit hosts, either.
19023 * keyboard.c (read_char):
19024 * lread.c (Fload): Remove casts to unsigned.
19026 * lisp.h (UNSIGNED_CMP): New macro.
19027 This fixes comparison bugs on 64-bit hosts.
19028 (ASCII_CHAR_P): Use it.
19029 * casefiddle.c (casify_object):
19030 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
19031 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
19032 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
19033 * dispextern.h (FACE_FROM_ID):
19034 * keyboard.c (read_char): Use UNSIGNED_CMP.
19036 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
19037 not to EMACS_INT, to avoid GCC warning.
19039 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
19041 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
19042 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
19043 isn't needed on 32-bit machines.
19045 * buffer.c (Fgenerate_new_buffer_name):
19046 Use EMACS_INT for count, not int.
19047 (advance_to_char_boundary): Return EMACS_INT, not int.
19049 * data.c (Qcompiled_function): Now static.
19051 * window.c (window_body_lines): Now static.
19053 * image.c (gif_load): Rename local to avoid shadowing.
19055 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
19056 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
19057 * alloc.c (make_save_value): Integer argument is now of type
19058 ptrdiff_t, not int.
19059 (mark_object): Use ptrdiff_t, not int.
19060 * lisp.h (pD): New macro.
19061 * print.c (print_object): Use it.
19063 * alloc.c: Use EMACS_INT, not int, to count objects.
19064 (total_conses, total_markers, total_symbols, total_vector_size)
19065 (total_free_conses, total_free_markers, total_free_symbols)
19066 (total_free_floats, total_floats, total_free_intervals)
19067 (total_intervals, total_strings, total_free_strings):
19068 Now EMACS_INT, not int. All uses changed.
19069 (Fgarbage_collect): Compute overall total using a double, so that
19070 integer overflow is less likely to be a problem. Check for overflow
19071 when converting back to an integer.
19072 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
19073 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
19074 These were 'int' variables that could overflow on 64-bit hosts;
19075 they were never used, so remove them instead of repairing them.
19076 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
19077 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
19078 Previously, this ceilinged at INT_MAX, but that doesn't work on
19080 (allocate_pseudovector): Don't use EMACS_INT when int would do.
19082 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
19083 (allocate_vectorlike): Check for ptrdiff_t overflow.
19084 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
19085 when a (possibly-narrower) signed value would do just as well.
19086 We prefer using signed arithmetic, to avoid comparison confusion.
19088 * alloc.c: Catch some string size overflows that we were missing.
19089 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
19090 for convenience in STRING_BYTES_MAX.
19091 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
19092 The definition here is exact; the one in lisp.h was approximate.
19093 (allocate_string_data): Check for string overflow. This catches
19094 some instances we weren't catching before. Also, it catches
19095 size_t overflow on (unusual) hosts where SIZE_MAX <= min

19539 * buffer.h (struct buffer.modtime): Now time_t, not int.
19540 * fileio.c (Fvisited_file_modtime): No need for time_t cast now.
19541 * undo.c (Fprimitive_undo): Use time_t, not int, for time_t value.
19543 Minor fixes for signed vs unsigned integers.
19544 * character.h (MAYBE_UNIFY_CHAR):
19545 * charset.c (maybe_unify_char):
19546 * keyboard.c (read_char, reorder_modifiers):
19547 XINT -> XFASTINT, since the integer must be nonnegative.
19548 * ftfont.c (ftfont_spec_pattern):
19549 * keymap.c (access_keymap, silly_event_symbol_error):
19550 XUINT -> XFASTINT, since the integer must be nonnegative.
19551 (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
19552 since it makes no difference and we prefer signed.
19553 * keyboard.c (record_char): Use XUINT when all the neighbors do.
19554 (access_keymap): NATNUMP -> INTEGERP, since the integer must be

19597 (Fwindow_minibuffer_p): Move up in code and simplify.
19598 (Fset_frame_selected_window): Move here from frame.c.
19600 (Fselected_window, select_window, Fselect_window): Move up in
19601 code. Minor doc-string fixes.
19603 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
19605 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
19606 Do not assume that spare memory exists; that assumption is valid
19607 only if SYSTEM_MALLOC.
19608 (LARGE_REQUEST): New macro, so that the issue of large requests
19609 is separated from the issue of spare memory.
19611 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
19613 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

19638 (x_clipboard_manager_error_1, x_clipboard_manager_error_2):
19639 New error handlers.
19640 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
19641 Obey Vx_select_enable_clipboard_manager. Catch errors in
19642 x_clipboard_manager_save (Bug#8779).
19643 (Vx_select_enable_clipboard_manager): New variable.
19644 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
19646 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
19648 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
19650 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19652 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
19653 in the current matrix if keep_current_p is non-zero.

19659 2011-06-03 Eli Zaretskii <eliz@gnu.org>
19661 Support bidi reordering of text covered by display properties.
19663 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
19664 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
19665 (bidi_cache_search, bidi_cache_iterator_state)
19666 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
19667 (bidi_level_of_next_char, bidi_move_to_visually_next):
19668 Support character positions inside a run of characters covered by a
19670 (bidi_paragraph_init, bidi_resolve_explicit_1)
19671 (bidi_level_of_next_char): Call bidi_fetch_char and
19672 bidi_fetch_char_advance instead of FETCH_CHAR and
19673 FETCH_CHAR_ADVANCE.

19675 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
19677 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
19678 instead of using explicit *_CHAR codes.
19679 (bidi_resolve_explicit, bidi_resolve_weak):
19680 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
19681 bidirectional text is supported only in multibyte buffers.
19682 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
19683 it to initialize the frame_window_p member of struct bidi_it.
19684 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
19685 (bidi_resolve_explicit, bidi_resolve_weak)

19687 bidi_it->nchars is non-positive.
19688 (bidi_level_of_next_char): Don't try to lookup the cache for the
19689 next/previous character if nothing is cached there yet, or if we
19690 were just reseat()'ed to a new position.
19692 * xdisp.c (set_cursor_from_row): Set start and stop points
19693 according to the row's direction when priming the loop that looks
19694 for the glyph on which to display cursor.
19695 (single_display_spec_intangible_p): Function deleted.
19696 (display_prop_intangible_p): Reimplement to call
19697 handle_display_spec instead of single_display_spec_intangible_p.
19698 Accept 3 additional arguments needed by handle_display_spec.
19699 This fixes incorrect cursor motion across display property with complex
19700 values: lists, `(when COND...)' forms, etc.
19701 (single_display_spec_string_p): Support property values that are
19702 lists with the argument STRING its top-level element.
19703 (display_prop_string_p): Fix the condition for processing a
19704 property that is a list to be consistent with handle_display_spec.
19705 (handle_display_spec): New function, refactored from the
19706 last portion of handle_display_prop.
19707 (compute_display_string_pos): Accept additional argument
19708 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
19709 value of a `display' property is a "replacing spec".
19710 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19711 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
19712 the display property, but just return a value indicating whether
19713 the display property will replace the characters it covers.
19714 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
19715 frame_window_p members of struct bidi_it.
19716 (compute_display_string_pos, compute_display_string_end):
19718 (push_it): Accept second argument POSITION, where pop_it should
19719 jump to continue iteration.
19720 (reseat_1): Initialize bidi_it.disp_pos.
19722 * keyboard.c (adjust_point_for_property): Adjust the call to
19723 display_prop_intangible_p to its new signature.
19725 * dispextern.h (struct bidi_it): New member frame_window_p.
19726 (bidi_init_it): Update prototypes.
19727 (display_prop_intangible_p): Update prototype.
19728 (compute_display_string_pos, compute_display_string_end):
19729 Declare prototypes.
19730 (struct bidi_it): New members nchars and disp_pos. ch_len is now
19733 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
19735 Malloc failure behavior now depends on size of allocation.
19736 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
19737 * lisp.h: Change signatures accordingly.
19738 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
19739 All callers changed. (Bug#8762)
19741 * gnutls.c: Use Emacs's memory allocators.
19742 Without this change, the gnutls library would invoke malloc etc.
19743 directly, which causes problems on non-SYNC_INPUT hosts, and which
19744 runs afoul of improving memory_full behavior. (Bug#8761)
19745 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19746 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19747 xfree instead of the default malloc, realloc, free.
19748 (Fgnutls_boot): No need to check for memory allocation failure,
19749 since xmalloc does that for us.
19751 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
19752 * category.c (hash_get_category_set):
19753 * ccl.c (ccl_driver):

19765 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
19766 (Fsxhash, Fgethash, Fputhash, Fmaphash):
19767 * image.c (make_image, search_image_cache, lookup_image)
19768 (xpm_put_color_table_h):
19769 * lisp.h (struct Lisp_Hash_Table):
19770 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
19771 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
19772 for hashes and hash indexes, instead of 'unsigned' and 'int'.
19773 * alloc.c (allocate_vectorlike):
19774 Check for overflow in vector size calculations.
19775 * ccl.c (ccl_driver):
19776 Check for overflow when converting EMACS_INT to int.
19777 * fns.c, image.c: Remove unnecessary static decls that would otherwise
19778 need to be updated by these changes.
19779 * fns.c (make_hash_table, maybe_resize_hash_table):
19780 Check for integer overflow with large hash tables.
19781 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19782 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19783 (SXHASH_REDUCE): New macro.
19784 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19785 Use it instead of discarding useful hash info with large hash values.
19786 (sxhash_float): New function.
19787 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19788 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19789 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19790 Rewrite to use FIXNUM_BITS, as this simplifies things.
19791 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19792 Adjust signatures to match updated version of code.
19793 (consing_since_gc): Now EMACS_INT, since a single hash table can
19794 use more than INT_MAX bytes.
19796 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
19798 Make it possible to build with GCC-4.6+ -O2 -flto.
19800 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
19802 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
19804 * minibuf.c (get_minibuffer, read_minibuf_unwind):
19805 Call minibuffer-inactive-mode.
19807 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
19809 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
19810 Update dependencies.
19812 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19814 * data.c (init_data): Remove code for UTS, this system is not
19817 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19819 Don't force ./temacs to start in terminal mode.
19821 * frame.c (make_initial_frame): Initialize faces in all cases, not
19822 only when CANNOT_DUMP is defined.
19823 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
19825 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19827 * dispnew.c (add_window_display_history): Use const for the string
19828 pointer. Remove declaration, not needed.
19830 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19832 Use 'inline', not 'INLINE'.
19833 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
19834 * alloc.c, fontset.c (INLINE): Remove.
19835 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
19836 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
19837 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
19838 * gmalloc.c (register_heapinfo): Use inline unconditionally.
19839 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
19841 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19843 Make it possible to run ./temacs.
19845 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19846 syms_of_callproc does the same thing. Remove test for
19847 "initialized", do it in the caller.
19848 * emacs.c (main): Avoid calling set_initial_environment when dumping.
19850 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
19852 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
19853 (read_minibuf): Use get_minibuffer.
19854 (syms_of_minibuf): Use DEFSYM.
19855 (Qmetadata): New var.
19856 * data.c (Qbuffer): Don't make it static.
19857 (syms_of_data): Use DEFSYM.
19859 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19861 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
19862 (CCL_CODE_MIN): New macro.
19864 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
19866 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
19868 * eval.c (Qdebug): Now static.
19869 * lisp.h (Qdebug): Remove decl. This reverts a part of the
19870 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
19871 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
19873 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19875 * image.c: Various fixes to ImageMagick code comments.
19876 (Fimagemagick_types): Doc fix.
19878 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
19880 Minor fixes prompted by GCC 4.6.0 warnings.
19882 * xselect.c (converted_selections, conversion_fail_tag): Now static.
19884 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
19885 (x_clipboard_manager_save_all): Move extern decl to ...
19886 * xterm.h: ... here, so that it can be checked for consistency.
19888 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19890 * xselect.c (x_clipboard_manager_save_frame)
19891 (x_clipboard_manager_save_all): New functions.
19892 (Fx_clipboard_manager_save): Lisp function deleted.
19894 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
19895 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
19897 * xterm.h: Update prototype.
19899 2011-05-28 William Xu <william.xwl@gmail.com>
19901 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
19902 exiting (Bug#8239).
19904 2011-05-28 Jim Meyering <meyering@redhat.com>
19906 Avoid a sign-extension bug in crypto_hash_function.
19907 * fns.c (to_uchar): Define.
19908 (crypto_hash_function): Use it to convert some newly-signed
19909 variables to unsigned, to avoid sign-extension bugs. For example,
19910 without this change, (md5 "truc") would evaluate to
19911 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19912 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19913 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19915 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19917 Integer overflow fixes.
19919 * dbusbind.c: Serial number integer overflow fixes.
19920 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19921 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19922 to hold a serial number that is too large for a fixnum.
19923 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19924 Check for serial numbers out of range. Decode any serial number
19925 that was so large that it became a float. (Bug#8722)
19927 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19928 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19929 Use XFASTINT rather than XUINT when numbers are nonnegative.
19930 (xd_append_arg, Fdbus_method_return_internal):
19931 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19932 arguments, check that Lisp number is nonnegative, rather than
19933 silently wrapping negative numbers around. (Bug#8722)
19934 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19937 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19939 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19941 ccl: Add integer overflow checks.
19942 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19943 (IN_INT_RANGE): New macros.
19944 (ccl_driver): Use them to check for integer overflow when
19945 decoding a CCL program. Many of the new checks are whether XINT (x)
19946 fits in int; it doesn't always, on 64-bit hosts. The new version
19947 doesn't catch all possible integer overflows, but it's an
19948 improvement. (Bug#8719)
19950 * alloc.c (make_event_array): Use XINT, not XUINT.
19951 There's no need for unsigned here.
19953 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19954 This follows up to the 2011-05-06 change that substituted uintptr_t
19955 for EMACS_INT. This case wasn't caught back then.
19957 Rework Fformat to avoid integer overflow issues.
19958 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19959 now (part of C89). Include <verify.h>.
19960 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19961 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19962 (Fformat): Avoid the prepass trying to compute sizes; it was only
19963 approximate and thus did not catch overflow reliably. Instead, walk
19964 through the format just once, formatting and computing sizes as we go,
19965 checking for integer overflow at every step, and allocating a larger
19966 buffer as needed. Keep track separately whether the format is
19967 multibyte. Keep only the most-recently calculated precision, rather
19968 than them all. Record whether each argument has been converted to
19969 string. Use EMACS_INT, not int, for byte and char and arg counts.
19970 Support field widths and precisions larger than INT_MAX. Avoid
19971 sprintf's undefined behavior with conversion specifications such as %#d
19972 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19973 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19974 formatting out-of-range floating point numbers with int
19975 formats. (Bug#8668)
19977 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19979 * data.c: Avoid integer truncation in expressions involving floats.
19980 * data.c: Include <intprops.h>.
19981 (arith_driver): When there's an integer overflow in an expression
19982 involving floating point, convert the integers to floating point
19983 so that the resulting value does not suffer from catastrophic
19984 integer truncation. For example, on a 64-bit host (* 4
19985 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19986 Do not rely on undefined behavior after integer overflow.
19988 merge count_size_as_multibyte, parse_str_to_multibyte
19989 * character.c, character.h (count_size_as_multibyte):
19990 Rename from parse_str_to_multibyte; all uses changed.
19991 Check for integer overflow.
19992 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19993 since it's now a duplicate of the other. This is more of
19994 a character than a buffer op, so better that it's in character.c.
19995 * fns.c, print.c: Adjust to above changes.
19997 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19999 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
20001 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20003 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20004 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
20005 (x_clipboard_manager_save): Now static.
20006 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
20008 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20009 (crypto_hash_function): Now static.
20010 Fix pointer signedness problems. Avoid unnecessary initializations.
20012 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
20014 * termhooks.h (Vselection_alist): Make it terminal-local.
20016 * terminal.c (create_terminal): Initialize it.
20018 * xselect.c: Support for clipboard managers.
20019 (Vselection_alist): Move to termhooks.h as terminal-local var.
20020 (LOCAL_SELECTION): New macro.
20021 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
20022 (symbol_to_x_atom): Remove gratuitous arg.
20023 (x_handle_selection_request, lisp_data_to_selection_data)
20024 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
20025 (x_own_selection, x_get_local_selection, x_convert_selection):
20026 New arg, specifying work frame. Use terminal-local Vselection_alist.
20027 (some_frame_on_display): Delete unused function.
20028 (Fx_own_selection_internal, Fx_get_selection_internal)
20029 (Fx_disown_selection_internal, Fx_selection_owner_p)
20030 (Fx_selection_exists_p): New optional frame arg.
20031 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
20032 (x_handle_selection_clear): Don't treat other terminals with the
20033 same keyboard specially. Use the terminal-local Vselection_alist.
20034 (x_clear_frame_selections): Use Frun_hook_with_args.
20036 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
20038 * xterm.h: Add support for those atoms.
20040 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
20042 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
20043 (converted_selections, conversion_fail_tag): New global variables.
20044 (x_selection_request_lisp_error): Free the above.
20045 (x_get_local_selection): Remove unnecessary code.
20046 (x_reply_selection_request): Args changed; handle arbitrary array
20047 of converted selections stored in converted_selections.
20048 Separate the XChangeProperty and SelectionNotify steps.
20049 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
20050 (x_convert_selection): New function.
20051 (x_handle_selection_event): Simplify.
20052 (x_get_foreign_selection): Don't ignore incoming requests while
20053 waiting for an answer; this will fail when we implement
20054 SAVE_TARGETS, and seems unnecessary anyway.
20055 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
20056 (Vx_sent_selection_functions): Doc fix.
20058 2011-05-26 Leo Liu <sdl.web@gmail.com>
20060 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
20062 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20064 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
20066 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
20067 for fringe update if it has periodic bitmap.
20068 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
20069 and fringe_bitmap_periodic_p.
20071 * fringe.c (get_fringe_bitmap_data): New function.
20072 (draw_fringe_bitmap_1, update_window_fringes): Use it.
20073 (update_window_fringes): Record periodicity of fringe bitmap in glyph
20074 row. Mark glyph row for fringe update if periodicity changed.
20076 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
20077 for fringe update unless it has periodic bitmap.
20079 2011-05-25 Kenichi Handa <handa@m17n.org>
20081 * xdisp.c (get_next_display_element): Set correct it->face_id for
20082 a static composition.
20084 2011-05-24 Leo Liu <sdl.web@gmail.com>
20087 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
20089 * fns.c (crypto_hash_function, Fsha1): New function.
20090 (Fmd5): Use crypto_hash_function.
20091 (syms_of_fns): Add Ssha1.
20093 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20095 * gnutls.c: Remove unused macros.
20096 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
20097 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
20098 Remove macros that are defined and never used.
20099 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
20101 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20103 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
20104 (Fx_get_selection_internal): Minor cleanup.
20105 (Fx_own_selection_internal): Rename arguments for consistency with
20108 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20110 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
20112 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20114 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
20116 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20118 * dispnew.c (scrolling_window): Don't exclude the case that the
20119 last enabled row in the desired matrix touches the bottom boundary.
20121 2011-05-21 Glenn Morris <rgm@gnu.org>
20123 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
20124 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
20125 and add some more files.
20127 2011-05-20 Eli Zaretskii <eliz@gnu.org>
20129 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
20130 report_file_error introduced by the change from 2011-05-07.
20132 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
20134 * systime.h (Time): Define only if emacs is defined.
20135 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
20136 where the include path doesn't have X11/X.h by default. See
20137 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
20139 2011-05-20 Kenichi Handa <handa@m17n.org>
20141 * composite.c (find_automatic_composition): Fix previous change.
20143 2011-05-20 Glenn Morris <rgm@gnu.org>
20145 * lisp.mk: New file, split from Makefile.in.
20146 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
20147 (shortlisp): Remove.
20148 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
20150 2011-05-19 Glenn Morris <rgm@gnu.org>
20152 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
20153 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
20154 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
20155 (lisp): Set the order to that of loadup.el.
20156 (shortlisp): Make it a copy of $lisp.
20157 (SOME_MACHINE_LISP): Remove.
20158 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
20159 Use just $shortlisp, not $SOME_MACHINE_LISP too.
20161 2011-05-18 Kenichi Handa <handa@m17n.org>
20163 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
20164 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
20165 (find_automatic_composition): Mostly rewrite for efficiency.
20167 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
20169 * makefile.w32-in: Update dependencies.
20171 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
20173 * menu.c: Include limits.h (fixes the MS-Windows build broken by
20174 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
20176 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
20178 Fix some integer overflow issues, such as string length overflow.
20180 * insdel.c (count_size_as_multibyte): Check for string overflow.
20182 * character.c (lisp_string_width): Check for string overflow.
20183 Use EMACS_INT, not int, for string indexes and lengths; in
20184 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
20185 the resulting string length overflows an EMACS_INT; instead,
20186 report a string overflow if no precision given. When checking for
20187 precision exhaustion, use a check that cannot possibly have
20188 integer overflow. (Bug#8675)
20189 * character.h (lisp_string_width): Adjust to new signature.
20191 * alloc.c (string_overflow): New function.
20192 (Fmake_string): Use it. This doesn't change behavior, but saves
20193 a few bytes and will simplify future changes.
20194 * character.c (string_escape_byte8): Likewise.
20195 * lisp.h (string_overflow): New decl.
20197 Fixups, following up to the user-interface timestamp change.
20198 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
20199 for UI timestamps, instead of unsigned long.
20200 * msdos.c (mouse_get_pos): Likewise.
20201 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
20202 * w32gui.h (Time): Define by including "systime.h" rather than by
20203 declaring it ourselves. (Bug#8664)
20205 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
20206 * image.c (clear_image_cache): Likewise.
20208 * term.c (term_mouse_position): Don't assume time_t wraparound.
20210 Be more systematic about user-interface timestamps.
20211 Before, the code sometimes used 'Time', sometimes 'unsigned long',
20212 and sometimes 'EMACS_UINT', to represent these timestamps.
20213 This change causes it to use 'Time' uniformly, as that's what X uses.
20214 This makes the code easier to follow, and makes it easier to catch
20215 integer overflow bugs such as Bug#8664.
20216 * frame.c (Fmouse_position, Fmouse_pixel_position):
20217 Use Time, not unsigned long, for user-interface timestamps.
20218 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
20219 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
20220 * keyboard.h (last_event_timestamp): Likewise.
20221 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
20222 * menu.h (xmenu_show): Likewise.
20223 * term.c (term_mouse_position): Likewise.
20224 * termhooks.h (struct input_event.timestamp): Likewise.
20225 (struct terminal.mouse_position_hook): Likewise.
20226 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
20227 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
20228 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
20229 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
20230 what it was before.
20231 * menu.h, termhooks.h: Include "systime.h", for Time.
20233 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
20234 Don't assume that the difference between two unsigned long values
20235 can fit into an integer. At this point, we know button_down_time
20236 <= event->timestamp, so the difference must be nonnegative, so
20237 there's no need to cast the result if double-click-time is
20238 nonnegative, as it should be; check that it's nonnegative, just in
20239 case. This bug is triggered when events are more than 2**31 ms
20240 apart (about 25 days). (Bug#8664)
20242 * xselect.c (last_event_timestamp): Remove duplicate decl.
20243 (x_own_selection): Remove needless cast to unsigned long.
20245 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
20246 that always fit in int. Use a sentinel instead of a counter, to
20247 avoid a temp and to allay GCC's concerns about possible int overflow.
20248 * frame.h (struct frame): Use int for menu_bar_items_used
20249 instead of EMACS_INT, since it always fits in int.
20251 * menu.c (grow_menu_items): Check for int overflow.
20253 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
20255 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
20256 Before, the code was not consistent. These values cannot exceed
20257 2**31 - 1 so there's no need to make them unsigned.
20258 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
20259 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
20260 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
20262 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
20264 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
20265 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
20266 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
20267 presumably because the widths might not match.
20269 * window.c (size_window): Avoid needless test at loop start.
20271 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
20273 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
20275 2011-05-12 Drew Adams <drew.adams@oracle.com>
20277 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
20279 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20281 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
20282 `width' to `bar_area_x' and `bar_area_width', respectively.
20283 (x_scroll_run): Take account of fringe background extension.
20285 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
20286 Rename local vars `left' and `width' to `bar_area_x' and
20287 `bar_area_width', respectively.
20288 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
20289 background extension.
20291 2011-05-10 Jim Meyering <meyering@redhat.com>
20293 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
20295 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
20297 * image.c (Finit_image_library): Return t for built-in image types,
20298 like pbm and xbm. (Bug#8640)
20300 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
20302 * w32menu.c (set_frame_menubar): Fix submenu allocation.
20304 2011-05-07 Eli Zaretskii <eliz@gnu.org>
20306 * w32console.c (Fset_screen_color): Doc fix.
20307 (Fget_screen_color): New function.
20308 (syms_of_ntterm): Defsubr it.
20310 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
20311 unlink the temporary file if Fcall_process didn't create it in the
20313 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
20314 child process will be redirected to a file specified with `:file'.
20315 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
20316 cue to call_process_cleanup not to close that handle.
20318 2011-05-07 Ben Key <bkey76@gmail.com>
20320 * makefile.w32-in: The bootstrap-temacs rule now makes use of
20321 one of two shell specific rules, either bootstrap-temacs-CMD or
20322 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
20323 to the previous implementation of the bootstrap-temacs rule.
20324 The bootstrap-temacs-CMD rule is similar to the previous
20325 implementation of the bootstrap-temacs rule except that it
20326 makes use of the ESC_CFLAGS variable instead of the CFLAGS
20329 These changes, along with some changes to nt/configure.bat,
20330 nt/gmake.defs, and nt/nmake.defs, are required to extend my
20331 earlier fix to add support for --cflags and --ldflags options
20332 that include quotes so that it works whether make uses cmd or
20335 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
20337 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
20338 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
20340 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
20341 a string. Handle both cases.
20342 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
20343 (Fdbus_register_method): Use Qinvalid_function.
20345 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20347 * makefile.w32-in: Update dependencies.
20348 (LISP_H): Add inttypes.h and stdin.h.
20349 (PROCESS_H): Add unistd.h.
20351 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20353 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20354 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20356 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20358 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20360 * term.c (vfatal): Remove stray call to va_end.
20361 It's not needed and the C Standard doesn't allow it here anyway.
20363 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20364 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20366 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20369 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20371 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20373 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20375 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20377 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20379 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20380 * charset.c (Fdefine_charset_internal): Don't initialize
20381 charset.code_space[15]. The value was garbage, on hosts with
20382 32-bit int (Bug#8600).
20384 * lread.c (read_integer): Be more consistent with string-to-number.
20385 Use string_to_number to do the actual conversion; this avoids
20386 rounding errors and fixes some other screwups. Without this fix,
20387 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20388 (digit_to_number): Move earlier, for benefit of read_integer.
20389 Return -1 if the digit is out of range for the base, -2 if it is
20390 not a digit in any supported base. (Bug#8602)
20392 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20394 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20395 to match comment at start of function. This also removes a
20396 GCC warning about overflow in a 32+64-bit port.
20398 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20400 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20401 Reported by Stefan Monnier in
20402 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20403 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20404 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20406 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20407 (EMACS_UINTPTR): Likewise, with uintptr_t.
20409 * lisp.h: Prefer 64-bit EMACS_INT if available.
20410 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20411 on 32-bit hosts that have 64-bit int, so that they can access
20413 However, temporarily disable this change unless the temporary
20414 symbol WIDE_EMACS_INT is defined.
20416 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20418 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20419 This removes an assumption that EMACS_INT and long are the same
20420 width as pointers. The assumption is true for Emacs porting targets
20421 now, but we want to make other targets possible.
20422 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20423 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20424 In the rest of the code, change types of integers that hold casted
20425 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20426 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20427 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20428 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20429 No need to cast type when ORing.
20430 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20431 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20432 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20433 assume EMACS_INT is the same width as char *.
20434 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20435 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20436 Remove no-longer-needed casts.
20437 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20438 (xg_tool_bar_help_callback, xg_make_tool_item):
20439 Use EMACS_INTPTR to hold an integer
20440 that will be cast to void *; this can avoid a GCC warning
20441 if EMACS_INT is not the same width as void *.
20442 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20443 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20444 (current_message_1, set_message_1):
20445 Use a local to convert to proper width without a cast.
20446 * xmenu.c (dialog_selection_callback): Likewise.
20448 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20449 Also, don't assume VALBITS / RAND_BITS is less than 5,
20450 and don't rely on undefined behavior when shifting a 1 left into
20452 * lisp.h (get_random): Change signature to match.
20454 * lread.c (hash_string): Use size_t, not int, for hash computation.
20455 Normally we prefer signed values; but hashing is special, because
20456 it's better to use unsigned division on hash table sizes so that
20457 the remainder is nonnegative. Also, size_t is the natural width
20458 for hashing into memory. The previous code used 'int', which doesn't
20459 retain enough info to hash well into very large tables.
20460 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20462 * dbusbind.c: Don't possibly lose pointer info when converting.
20463 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20464 Use XPNTR rather than XHASH, so that the high-order bits of
20465 the pointer aren't lost when converting through void *.
20467 * eval.c (Fautoload): Don't double-shift a pointer.
20469 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
20471 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20473 * gnutls.c (DEF_GNUTLS_FN):
20474 * image.c (DEF_IMGLIB_FN): Make function pointers static.
20476 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
20478 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
20481 2011-05-05 Eli Zaretskii <eliz@gnu.org>
20483 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
20484 New version that can reserve upto 2GB of heap space.
20486 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
20488 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
20490 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
20492 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
20493 `gnutls_certificate_set_x509_key_file'.
20495 2011-05-05 Juanma Barranquero <lekktu@gmail.com>

20498 Update dependencies.
20500 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20502 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
20503 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
20504 Remove unused parameter `fildes'.
20505 * process.c (read_process_output, send_process): Don't pass it.
20507 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20509 Fix previous change: the library cache is defined in w32.c.
20510 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
20511 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
20513 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20515 Implement dynamic loading of GnuTLS on Windows.
20517 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
20518 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
20519 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20522 * gnutls.c (Qgnutls_dll): Define.

20531 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
20532 (Fgnutls_available_p): New function.
20533 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

20541 (w32_delayed_load): Move to w32.c.
20543 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
20545 * w32.c (QCloaded_from, Vlibrary_cache): Define.
20546 (w32_delayed_load): Move from image.c. When loading a library, record
20547 its filename in the :loaded-from property of the library id.
20548 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
20549 Initialize and staticpro them.
20550 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
20552 * process.c: Include lisp.h before w32.h, not after.
20553 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20554 instead of gnutls_record_check_pending.
20556 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
20558 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20560 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
20561 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
20564 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
20566 * xterm.c (x_set_frame_alpha): Do not set property on anything
20567 else than FRAME_X_OUTER_WINDOW (Bug#8608).
20569 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20571 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
20573 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20575 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
20576 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

20581 (Qgnutls_bootprop_hostname, Qgnutls_bootprop_verify_flags)
20582 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
20583 (Qgnutls_bootprop_callbacks_verify): Make static.
20585 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
20587 * callproc.c: Indentation fixup.
20589 * sysdep.c (wait_for_termination_1): Make static.
20590 (wait_for_termination, interruptible_wait_for_termination):
20591 Move after wait_for_termination_1.
20593 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
20595 * sysdep.c (interruptible_wait_for_termination): New function
20596 which is like wait_for_termination, but allows keyboard
20599 * callproc.c (Fcall_process): Add (:file "file") as an option for
20601 (Fcall_process_region): Ditto.
20603 2011-04-30 Eli Zaretskii <eliz@gnu.org>
20605 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
20606 rather than `XVECTOR (FOO)->size'.
20608 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20609 inttypes.h, as a gnulib replacement is used if it not available in
20612 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20614 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
20615 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
20616 of MOST_POSITIVE_FIXNUM. (Bug#8528)
20618 * coding.c (coding_alloc_by_realloc): Error out if destination
20619 will grow beyond MOST_POSITIVE_FIXNUM.
20620 (decode_coding_emacs_mule): Abort if there isn't enough place in
20621 charbuf for the composition carryover bytes. Reserve an extra
20622 space for up to 2 characters produced in a loop.
20623 (decode_coding_iso_2022): Abort if there isn't enough place in
20624 charbuf for the composition carryover bytes.
20626 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20628 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
20629 aborting when %lld or %lll format is passed.
20630 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
20631 %llo or %llx format is passed. (Bug#8545)
20633 * window.c (window_scroll_line_based): Use a marker instead of
20634 simple variables to record original value of point. (Bug#7952)
20636 * doprnt.c (doprnt): Fix the case where a multibyte sequence
20637 produced by %s or %c overflows available buffer space. (Bug#8545)
20639 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20641 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
20642 (SIZE_MAX): Move defn after all includes, as they might #define it.
20644 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20646 * w32.c (init_environment): Warn about defaulting HOME to C:\.
20648 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20650 * keyboard.c (Qdelayed_warnings_hook): Define.
20651 (command_loop_1): Run `delayed-warnings-hook'
20652 if Vdelayed_warnings_list is non-nil.
20653 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
20654 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
20656 2011-04-28 Eli Zaretskii <eliz@gnu.org>
20658 * doprnt.c (doprnt): Don't return value smaller than the buffer
20659 size if the message was truncated. (Bug#8545).
20661 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20663 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
20664 (Fx_window_property): #if-0 the whole functions, not just the bodies.
20666 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20668 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
20670 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20672 * makefile.w32-in: Update dependencies.
20674 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20676 Improve `doprnt' and its usage. (Bug#8545)
20677 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20678 `format_end'. Remove support for %l as a conversion specifier.
20679 Don't use xrealloc. Improve diagnostics when the %l size modifier
20680 is used. Update the commentary.
20682 * eval.c (verror): Simplify calculation of size_t.
20684 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20687 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20689 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20692 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20694 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20695 This makes this file independent of the recent pseudovector change.
20697 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20699 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20701 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20702 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20703 Remove unused local.
20704 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20706 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20707 GCC 4.6.0 optimizes based on type-based alias analysis.
20708 For example, if b is of type struct buffer * and v of type struct
20709 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20710 != &v->size, and therefore "v->size = 1; b->size = 2; return
20711 v->size;" must therefore return 1. This assumption is incorrect
20712 for Emacs, since it type-puns struct Lisp_Vector * with many other
20713 types. To fix this problem, this patch adds a new type struct
20714 vectorlike_header that documents the constraints on layout of vectors
20715 and pseudovectors, and helps optimizing compilers not get fooled
20716 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20717 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20718 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20720 (XSETPVECTYPE): Rewrite in terms of new macro.
20721 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20722 This is a bit clearer, and further avoids the possibility of
20723 undesirable aliasing.
20724 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20725 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20726 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20727 since Lisp_Subr is a special case (no "next" field).
20728 (ASIZE): Now uses header.size rather than size.
20729 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20730 to avoid the hassle of writing XVECTOR (foo)->header.size.
20731 (struct vectorlike_header): New type.
20732 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20733 object, to help avoid aliasing.
20734 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20735 (SUBRP): Likewise, since Lisp_Subr is a special case.
20736 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20737 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20738 (struct Lisp_Hash_Table): Combine first two members into a single
20739 struct vectorlike_header member. All uses of "size" and "next" members
20740 changed to be "header.size" and "header.next".
20741 * buffer.h (struct buffer): Likewise.
20742 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20743 * frame.h (struct frame): Likewise.
20744 * process.h (struct Lisp_Process): Likewise.
20745 * termhooks.h (struct terminal): Likewise.
20746 * window.c (struct save_window_data, struct saved_window): Likewise.
20747 * window.h (struct window): Likewise.
20748 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20749 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20750 * buffer.c (init_buffer_once): Likewise.
20751 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20753 * process.c (Fformat_network_address): Use local var for size,
20756 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20758 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20759 * data.c (atof): Remove decl; no longer used or needed.
20760 (digit_to_number): Move to lread.c.
20761 (Fstring_to_number): Use new string_to_number function, to be
20762 consistent with how the Lisp reader treats infinities and NaNs.
20763 Do not assume that floating-point numbers represent EMACS_INT
20764 without losing information; this is not true on most 64-bit hosts.
20765 Avoid double-rounding errors, by insisting on integers when
20766 parsing non-base-10 numbers, as the documentation specifies.
20767 * lisp.h (string_to_number): New decl, replacing ...
20768 (isfloat_string): Remove.
20769 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20770 (read1): Do not accept +. and -. as integers; this
20771 appears to have been a coding error. Similarly, do not accept
20772 strings like +-1e0 as floating point numbers. Do not report
20773 overflow for integer overflows unless the base is not 10 which
20774 means we have no simple and reliable way to continue.
20775 Break out the floating-point parsing into a new
20776 function string_to_number, so that Fstring_to_number parses
20777 floating point numbers consistently with the Lisp reader.
20778 (digit_to_number): Move here from data.c. Make it static inline.
20779 (E_CHAR, EXP_INT): Remove, replacing with ...
20780 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20781 (string_to_number): New function, replacing isfloat_string.
20782 This function checks for valid syntax and produces the resulting
20783 Lisp float number too. Rework it so that string-to-number
20784 no longer mishandles examples like "1.0e+". Use strtoumax,
20785 so that overflow for non-base-10 numbers is reported only when
20786 there's no portable and simple way to convert to floating point.
20788 * textprop.c (set_text_properties_1): Rewrite for clarity,
20789 and to avoid GCC warning about integer overflow.
20791 * intervals.h (struct interval): Use EMACS_INT for members
20792 where EMACS_UINT might cause problems. See
20793 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20794 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20795 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20797 (offset_intervals): Tell GCC not to worry about length overflow
20798 when negating a negative length.
20800 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20801 (overrun_check_free): Likewise.
20803 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20804 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20807 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20808 (gnutls_make_error): Rename local to avoid shadowing.
20809 (gnutls_emacs_global_deinit): ifdef out; not used.
20810 (Fgnutls_boot): Use const for pointer to readonly storage.
20811 Comment out unused local. Fix pointer signedness problems.
20813 * lread.c (openp): Don't stuff size_t into an 'int'.
20814 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20815 about possible signed overflow.
20817 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20818 (GDK_KEY_g): Don't define if already defined.
20819 (xg_prepare_tooltip): Avoid pointer signedness problem.
20820 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20822 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20823 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20825 * xfns.c (Fx_window_property): Simplify a bit,
20826 to make a bit faster and to avoid GCC 4.6.0 warning.
20827 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20829 * fns.c (internal_equal): Don't assume size_t fits in int.
20831 * alloc.c (compact_small_strings): Tighten assertion a little.
20833 Replace pEd with more-general pI, and fix some printf arg casts.
20834 * lisp.h (pI): New macro, generalizing old pEd macro to other
20835 conversion specifiers. For example, use "...%"pI"d..." rather
20836 than "...%"pEd"...".
20837 (pEd): Remove. All uses replaced with similar uses of pI.
20838 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20839 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20840 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20841 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20842 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20843 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20844 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20846 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20847 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20848 * print.c (safe_debug_print, print_object): Likewise.
20849 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20851 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20852 avoiding the 0 flag, which is not portable.
20853 * process.c (Fmake_network_process): Use pI to avoid cast.
20854 * region-cache.c (pp_cache): Likewise.
20855 * xdisp.c (decode_mode_spec): Likewise.
20856 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
20857 behavior on 64-bit hosts with printf arg.
20858 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
20859 (x_stop_queuing_selection_requests): Likewise.
20860 (x_get_window_property): Don't truncate byte count to an 'int'
20863 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20864 here, since it parses constructs like leading '-' and spaces,
20865 which are not wanted; and it overflows with large numbers.
20866 Instead, simply match F[0-9]+, which is what is wanted anyway.
20868 * alloc.c: Remove unportable assumptions about struct layout.
20869 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20870 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20871 (allocate_vectorlike, make_pure_vector): Use the new macros,
20872 plus offsetof, to remove unportable assumptions about struct layout.
20873 These assumptions hold on all porting targets that I know of, but
20874 they are not guaranteed, they're easy to remove, and removing them
20875 makes further changes easier.
20877 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20878 This doesn't fix a bug but makes the code clearer.
20879 (string_overrun_cookie): Now const. Use initializers that
20880 don't formally overflow signed char, to avoid warnings.
20881 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20882 can cause Emacs to crash when string overrun checking is enabled.
20883 (allocate_buffer): Don't assume sizeof (struct buffer) is a
20884 multiple of sizeof (EMACS_INT); it need not be, if
20885 alignof(EMACS_INT) < sizeof (EMACS_INT).
20886 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
20888 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

20917 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
20918 "cast to pointer from integer of different size".
20920 Improve doprnt and its use in verror. (Bug#8545)
20921 * doprnt.c (doprnt): Document the set of format control sequences
20922 supported by the function. Use SAFE_ALLOCA instead of always
20925 * eval.c (verror): Don't limit the buffer size at size_max-1, that
20926 is one byte too soon. Don't use xrealloc; instead xfree and
20929 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
20931 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

20937 parameters of `gnutls-boot' and documented those parameters in the
20938 docstring. Start callback support.
20939 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
20940 unless a fatal error occurred. Call gnutls_alert_send_appropriate

21038 * callint.c (Fcall_interactively): When displaying error message
21039 about invalid control letter, pass the character's codepoint, not

21044 codepoint of an invalid character, to avoid displaying a bogus
21047 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
21048 `error', not SYMBOL_NAME itself.

21053 * charset.c (check_iso_charset_parameter): Fix incorrect argument
21054 to `error' in error message about FINAL_CHAR argument. Make sure
21055 FINAL_CHAR is a character, and use %c when it is passed as
21056 argument to `error'.
21058 2011-04-23 Eli Zaretskii <eliz@gnu.org>
21060 * s/ms-w32.h (localtime): Redirect to sys_localtime.
21062 * w32.c: Include <time.h>.

21122 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
21123 by pacifying GCC about it. Maybe it's time to retire it?
21124 * xfaces.c (USG, __TIMEVAL__): Likewise.
21126 * dispextern.h (struct redisplay_interface): Rename param
21127 to avoid shadowing.
21128 * termhooks.h (struct terminal): Likewise.
21129 * xterm.c (xembed_send_message): Likewise.

21245 * nsfont.m: Fixed bugs in ns_get_family and
21246 ns_descriptor_to_entity that were caused by using free to
21247 deallocate memory blocks that were allocated by xmalloc (via
21248 xstrdup). This caused Emacs to crash when compiled with
21249 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
21250 --enable-checking=xmallocoverrun). xfree is now used to
21251 deallocate these memory blocks.

21265 (emacs_read, emacs_write): Remove check for negative size, as the
21266 Emacs source code has been audited now.
21267 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
21268 (emacs_read, emacs_write): Use it.
21269 * process.c (send_process): Adjust to the new signatures of
21270 emacs_write and emacs_gnutls_write. Do not attempt to store
21271 a byte offset into an 'int'; it might overflow.
21272 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

21296 * font.c (Qopentype): Don't make static (used from w32uniscribe.c).
21298 2011-04-14 Paul Eggert <eggert@cs.ucla.edu>

21704 * syntax.c (Fsyntax_table_p): New forward static decl.
21705 (skip_chars): Remove duplicate decl.

21719 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21721 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21722 when at ZV. (Bug#8487)
21724 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
21726 * charset.c (Fclear_charset_maps): Use xfree instead of free.
21728 * keyboard.c (parse_tool_bar_item): Likewise.
21729 * sound.c (sound_cleanup, alsa_close): Likewise.
21730 * termcap.c (tgetent): Likewise.
21731 * xfns.c (x_default_font_parameter): Likewise.
21732 * xsettings.c (read_and_apply_settings): Likewise.
21734 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21735 (overrun_check_free): Protoize.
21737 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21739 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21740 since callers should never pass a negative size.
21741 Change the signature to match that of plain 'read' and 'write'; see
21742 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21743 * lisp.h: Update prototypes of emacs_write and emacs_read.
21745 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21747 * xdisp.c (redisplay_window): Don't try to determine the character
21748 position of the scroll margin if the window start point w->startp
21749 is outside the buffer's accessible region. (Bug#8468)
21751 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21753 Fix write-region and its subroutines for buffers > 2GB.
21754 * fileio.c (a_write, e_write): Modify declaration of arguments and
21755 local variables to support buffers larger than 2GB.
21756 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21758 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21759 argument, local variables, and return value.
21761 * lisp.h: Update prototypes of emacs_write and emacs_read.
21763 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21765 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21767 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21769 Fix more problems found by GCC 4.6.0's static checks.
21771 * xdisp.c (vmessage): Use a better test for character truncation.
21773 * charset.c (load_charset_map): <, not <=, for optimization,
21774 and to avoid potential problems with integer overflow.
21775 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21776 * casetab.c (set_identity, shuffle): Likewise.
21777 * editfns.c (Fformat): Likewise.
21778 * syntax.c (skip_chars): Likewise.
21780 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21781 This also lets GCC 4.6.0 generate slightly better loop code.
21783 * callint.c (Fcall_interactively): <, not <=, for optimization.
21784 (Fcall_interactively): Count the number of arguments produced,
21785 not the number of arguments given. This is simpler and lets GCC
21786 4.6.0 generate slightly better code.
21788 * ftfont.c: Distingish more carefully between FcChar8 and char.
21789 The previous code passed unsigned char * to a functions like
21790 strlen and xstrcasecmp that expect char *, which does not
21791 conform to the C standard.
21792 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21793 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21794 char * when the C standard requires it.
21796 * keyboard.c (read_char): Remove unused var.
21798 * eval.c: Port to Windows vsnprintf (Bug#8435).
21799 Include <limits.h>.
21800 (SIZE_MAX): Define if the headers do not.
21801 (verror): Do not give up if vsnprintf returns a negative count.
21802 Instead, grow the buffer. This ports to Windows vsnprintf, which
21803 does not conform to C99. Problem reported by Eli Zaretskii.
21804 Also, simplify the allocation scheme, by avoiding the need for
21805 calling realloc, and removing the ALLOCATED variable.
21807 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21809 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21810 But keep the doprint source code for now, as we might revamp it
21811 and use it again (Bug#8435).
21812 * lisp.h (doprnt): Remove.
21813 * Makefile.in (base_obj): Remove doprnt.o.
21814 * deps.mk (doprnt.o): Remove.
21816 error: Print 32- and 64-bit integers portably (Bug#8435).
21817 Without this change, on typical 64-bit hosts error ("...%d...", N)
21818 was used to print both 32- and 64-bit integers N, which relied on
21819 undefined behavior.
21820 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21821 * lisp.h (error, verror): Mark as printf-like functions.
21822 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21823 Report overflow in size calculations when allocating printf buffer.
21824 Do not truncate output string at its first null byte.
21825 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21826 Truncate the output at a character boundary, since vsnprintf does not
21828 * charset.c (check_iso_charset_parameter): Convert internal
21829 character to string before calling 'error', since %c now has the
21831 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21832 overflow when computing char to be passed to 'error'. Do not
21833 pass Lisp_Object to 'error'; pass the integer instead.
21834 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21835 formatted with plain %d.
21837 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21839 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
21841 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
21843 * xterm.c (x_catch_errors): Remove duplicate declaration.
21845 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
21847 * xdisp.c, lisp.h (message_nolog): Remove; unused.
21849 2011-04-10 Jim Meyering <meyering@redhat.com>
21851 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
21852 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
21853 return ssize_t not "int", and use size_t as the buffer length.
21854 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
21855 * gnutls.h: Update declarations.
21856 * process.c (read_process_output): Use ssize_t, to match.
21857 (send_process): Likewise.
21859 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21861 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
21863 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21865 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
21866 Use unsigned char, to match FcChar8 type definition.
21868 * xterm.c (handle_one_xevent):
21869 * xmenu.c (create_and_show_popup_menu):
21870 * xselect.c (x_decline_selection_request)
21871 (x_reply_selection_request): Avoid type-punned deref of X events.
21873 2011-04-09 Eli Zaretskii <eliz@gnu.org>
21875 Fix some uses of `int' instead of EMACS_INT.
21876 * search.c (string_match_1, fast_string_match)
21877 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
21878 (scan_buffer, find_next_newline_no_quit)
21879 (find_before_next_newline, search_command, Freplace_match)
21880 (Fmatch_data): Make some `int' variables be EMACS_INT.
21882 * xdisp.c (display_count_lines): 3rd argument and return value now
21883 EMACS_INT. All callers changed.
21884 (pint2hrstr): Last argument is now EMACS_INT.
21886 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
21887 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
21888 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
21889 (decode_coding_utf_16, decode_coding_emacs_mule)
21890 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
21891 (decode_coding_ccl, decode_coding_charset)
21892 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
21893 (decode_coding_iso_2022, decode_coding_emacs_mule)
21894 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
21895 <char_offset, last_offset>: Declare EMACS_INT.
21896 (encode_coding_utf_8, encode_coding_utf_16)
21897 (encode_coding_emacs_mule, encode_invocation_designation)
21898 (encode_designation_at_bol, encode_coding_iso_2022)
21899 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
21900 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
21902 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
21903 (encode_invocation_designation): Last argument P_NCHARS is now
21905 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
21906 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
21908 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
21911 * ccl.c (Fccl_execute_on_string): Declare some variables
21914 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
21916 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
21918 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
21920 * process.c (Fformat_network_address): Doc fix.
21922 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
21924 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
21926 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
21928 * keyboard.c (read_char): Call Lisp function help-form-show,
21929 instead of using internal_with_output_to_temp_buffer.
21930 (Qhelp_form_show): New var.
21931 (syms_of_keyboard): Use DEFSYM macro.
21933 * print.c (internal_with_output_to_temp_buffer): Function deleted.
21935 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
21937 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
21939 * process.c (Flist_processes): Remove to Lisp.
21940 (list_processes_1): Delete.

21944 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
21946 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
21948 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
21950 Fix more problems found by GCC 4.6.0's static checks.

21954 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
21956 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
21958 * xdisp.c (vmessage): Mark as a printf-like function.
21960 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
21962 * sound.c (sound_warning): Don't crash if arg contains a printf format.
21964 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
21965 printf-like functions.
21966 (tiff_load): Add casts to remove these marks before passing them
21967 to system-supplied API.
21969 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21971 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21972 This avoids several warnings with gcc -Wstrict-overflow.
21973 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21974 directly, rather than having caller test rule sign. This avoids
21975 some unnecessary tests.
21976 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21977 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21978 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21980 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21981 (xfont_open): Avoid unnecessary tests.
21983 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21985 * composite.h, composite.c (composition_gstring_put_cache):
21986 Use EMACS_INT, not int, for length.

21989 breaking out part of COMPOSITION_DECODE_RULE.
21990 (COMPOSITION_DECODE_RULE): Use it.

21992 by using the new macro.
21994 * textprop.c (set_text_properties_1): Change while to do-while,
21995 since the condition is always true at first.
21997 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21998 (interval_deletion_adjustment): Return unsigned value.
22001 * process.c (list_processes_1, create_pty, read_process_output):

22011 (update_syntax_table): Use unsigned instead of int.
22013 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
22014 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
22015 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
22017 * print.c (print_error_message): Avoid int overflow.
22019 * font.c (font_list_entities): Redo for clarity,
22020 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
22022 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
22023 (font_score): Avoid potential overflow in diff calculation.
22025 * fns.c (substring_both): Remove var that is set but not used.
22026 (sxhash): Redo loop for clarity and to avoid wraparound warning.
22028 * eval.c (funcall_lambda): Rename local to avoid shadowing.
22030 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
22031 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
22032 can always succeed if overflow has undefined behavior.
22034 * search.c (boyer_moore, wordify): Remove vars set but not used.
22035 (wordify): Omit three unnecessary tests.
22037 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
22038 All callers changed. This avoids the need for an unused var.
22040 * casefiddle.c (casify_region): Remove var that is set but not used.
22042 * dired.c (file_name_completion): Remove var that is set but not used.
22044 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
22046 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
22047 (Finsert_file_contents): Remove unnecessary code checking fd.
22049 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
22050 Check for integer overflow on size calculations.
22052 * buffer.c (Fprevious_overlay_change): Remove var that is set
22055 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
22056 Remove vars that are set but not used.
22057 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
22058 (timer_check_2): Mark vars as initialized.
22060 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
22062 * image.c (lookup_image): Remove var that is set but not used.
22063 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
22065 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
22066 that are set but not used.
22068 * xfns.c (make_invisible_cursor): Don't return garbage
22069 if XCreateBitmapFromData fails (Bug#8410).
22071 * xselect.c (x_get_local_selection, x_handle_property_notify):
22072 Remove vars that are set but not used.
22074 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

22084 (map_tty_color) [!defined MSDOS]: Likewise.
22086 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
22088 * coding.c: Remove vars that are set but not used.
22089 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
22090 All callers changed.
22091 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
22092 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
22093 (decode_coding_charset): Remove vars that are set but not used.
22095 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
22096 that is set but not used.
22098 * print.c (print_object): Remove var that is set but not used.
22100 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
22101 The gnulib version avoids calling malloc in the usual case,
22102 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
22103 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
22104 * filelock.c (current_lock_owner): Likewise.
22105 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
22106 * sysdep.c: Include allocator.h, careadlinkat.h.
22107 (emacs_no_realloc_allocator): New static constant.
22108 (emacs_readlink): New function.
22109 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
22110 ../lib/careadlinkat.h.
22112 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
22114 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
22115 first non-nil return value).
22117 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
22119 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
22120 if not defined (Bug#8403).
22122 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
22124 * xdisp.c (display_count_lines): Remove parameter `start',
22125 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22126 (get_char_face_and_encoding): Remove parameter `multibyte_p',

22129 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
22130 and thereabouts. All callers changed.
22131 (get_per_char_metric): Remove parameter `f', unused since
22132 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
22134 2011-04-02 Jim Meyering <meyering@redhat.com>
22136 do not dereference NULL upon failed strdup
22137 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
22138 (ns_get_family): Likewise.
22140 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
22142 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
22144 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
22146 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or

22162 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
22164 (syms_of_lread): Declare `lexical-binding'.
22166 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
22168 * keyboard.c (eval_dyn): New fun.
22169 (menu_item_eval_property): Use it.
22171 * image.c (parse_image_spec): Use Ffunctionp.
22173 * fns.c (concat, mapcar1): Accept byte-code-functions.
22175 * eval.c (Fsetq): Handle lexical vars.
22176 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
22177 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
22178 (FletX, Flet): Obey lexical binding.
22179 (Fcommandp): Handle closures.
22180 (Feval): New `lexical' arg.
22181 (eval_sub): New function extracted from Feval. Use it almost
22182 everywhere where Feval was used. Look up vars in lexical env.
22184 (Ffunctionp): Move from subr.el.
22185 (Ffuncall): Handle closures.
22186 (apply_lambda): Remove `eval_flags'.
22187 (funcall_lambda): Handle closures and new byte-code-functions.
22188 (Fspecial_variable_p): New function.
22189 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
22190 but without exporting it to Lisp.
22192 * doc.c (Fdocumentation, store_function_docstring):
22193 * data.c (Finteractive_form): Handle closures.
22195 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
22198 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
22200 (exec_byte_code): New function extracted from Fbyte_code to handle new
22201 calling convention for byte-code-functions. Add new byte-codes.
22203 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
22205 * alloc.c (Fmake_symbol): Init new `declared_special' field.
22207 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22209 * xdisp.c (redisplay_internal): Fix prototype.
22211 2011-03-31 Eli Zaretskii <eliz@gnu.org>
22213 * xdisp.c (SCROLL_LIMIT): New macro.
22214 (try_scrolling): Use it when setting scroll_limit.
22215 Limit scrolling to 100 screen lines.
22216 (redisplay_window): Even when falling back on "recentering",
22217 position point in the window according to scroll-conservatively,
22218 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
22220 (try_scrolling): When point is above the window, allow searching
22221 as far as scroll_max, or one screenful, to compute vertical
22222 distance from PT to the scroll margin position. This prevents
22223 try_scrolling from unnecessarily failing when
22224 scroll-conservatively is set to a value slightly larger than the
22225 window height. Clean up the case of PT below the margin at bottom
22226 of window: scroll_max can no longer be INT_MAX. When aggressive
22227 scrolling is in use, don't let point enter the opposite scroll
22228 margin as result of the scroll.
22229 (syms_of_xdisp) <scroll-conservatively>: Document the
22230 threshold of 100 lines for never-recentering scrolling.
22232 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22234 * dispextern.h (move_it_by_lines):
22235 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
22236 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
22237 (message_log_check_duplicate): Remove parameters `prev_bol' and
22238 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22239 (redisplay_internal): Remove parameter `preserve_echo_area',
22240 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
22242 * indent.c (Fvertical_motion):
22243 * window.c (window_scroll_pixel_based, Frecenter):
22244 Don't pass `need_y_p' to `move_it_by_lines'.
22246 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
22248 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
22249 steal a few bits to be more compact.
22250 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
22251 Remove unneeded casts.
22253 * bytecode.c (Fbyte_code): CAR and CDR can GC.
22255 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
22257 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
22258 binding" message (bug#7967).
22260 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
22262 Fix more problems found by GCC 4.6.0's static checks.
22264 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
22265 Remove unused local var.
22267 * editfns.c (Fmessage_box): Remove unused local var.
22269 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
22270 (note_mode_line_or_margin_highlight, note_mouse_highlight):
22271 Omit unused local vars.
22272 * window.c (shrink_windows): Omit unused local var.
22273 * menu.c (digest_single_submenu): Omit unused local var.
22274 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
22275 Omit unused local var.
22277 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
22278 Don't assume string length fits in int.
22279 (keyremap_step, read_key_sequence): Use size_t for sizes.
22280 (read_key_sequence): Don't check last_real_key_start redundantly.
22282 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
22283 instead of alloca (Bug#8344).
22285 * eval.c (Fbacktrace): Don't assume nargs fits in int.
22286 (Fbacktrace_frame): Don't assume nframes fits in int.
22288 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
22290 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
22293 * term.c (produce_glyphless_glyph): Remove unnecessary test.
22295 * cm.c (calccost): Turn while-do into do-while, for clarity.
22297 * keyboard.c (syms_of_keyboard): Use the same style as later
22298 in this function when indexing through an array. This also
22299 works around GCC bug 48267.
22301 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
22303 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
22305 * chartab.c (sub_char_table_ref_and_range): Redo for slight
22306 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
22308 * keyboard.c, keyboard.h (num_input_events): Now size_t.
22309 This avoids undefined behavior on integer overflow, and is a bit
22310 more convenient anyway since it is compared to a size_t variable.
22312 Variadic C functions now count arguments with size_t, not int.
22313 This avoids an unnecessary limitation on 64-bit machines, which
22314 caused (substring ...) to crash on large vectors (Bug#8344).
22315 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
22316 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
22317 All variadic functions and their callers changed accordingly.
22318 (struct gcpro.nvars): Now size_t, not int. All uses changed.

22320 * editfns.c (general_insert_function): Likewise.
22321 * eval.c (struct backtrace.nargs, interactive_p)
22322 (internal_condition_case_n, run_hook_with_args, apply_lambda)
22323 (funcall_lambda, mark_backtrace): Likewise.
22324 * fns.c (concat): Likewise.
22325 * frame.c (x_set_frame_parameters): Likewise.
22326 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
22327 0 if not found, not -1. All callers changed.
22329 * alloc.c (garbage_collect): Don't assume stack size fits in int.
22330 (stack_copy_size): Now size_t, not int.
22331 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
22333 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
22335 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
22336 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
22337 All callers changed.
22339 * lisp.h (multibyte_char_to_unibyte):
22340 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
22341 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
22342 * character.h (CHAR_TO_BYTE8):
22343 * cmds.c (internal_self_insert):
22344 * editfns.c (general_insert_function):
22345 * keymap.c (push_key_description):
22346 * search.c (Freplace_match):
22347 * xdisp.c (message_dolog, set_message_1): All callers changed.
22349 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
22351 * keyboard.c (safe_run_hook_funcall): New function.
22352 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
22353 don't set the hook to nil, but remove the offending function instead.
22354 (Qcommand_hook_internal): Remove, unused.
22355 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
22356 Vcommand_hook_internal.
22358 * eval.c (enum run_hooks_condition): Remove.
22359 (funcall_nil, funcall_not): New functions.
22360 (run_hook_with_args): Call each function through a `funcall' argument.
22361 Remove `cond' argument, now redundant.
22362 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
22363 (Frun_hook_with_args_until_failure): Adjust accordingly.
22364 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
22366 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
22368 * dispextern.h (string_buffer_position): Remove declaration.
22370 * print.c (strout): Remove parameter `multibyte', unused since
22371 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
22373 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
22374 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
22375 All callers changed.
22377 * w32.c (_wsa_errlist): Use braces for struct initializers.
22379 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
22380 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
22381 All callers changed.
22382 (string_buffer_position): Likewise. Also, make static (it's never
22383 used outside xdisp.c).
22384 (cursor_row_p): Remove parameter `w', unused since
22385 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

22387 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
22388 All callers changed.
22390 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
22392 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.
22394 2011-03-27 Anders Lindgren <andlind@gmail.com>
22396 * nsterm.m (ns_menu_bar_is_hidden): New variable.
22397 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
22398 (ns_update_auto_hide_menu_bar): New functions.
22399 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

22403 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
22405 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
22407 * nsmenu.m (runDialogAt): Remove argument to timer_check.
22409 2011-03-27 Glenn Morris <rgm@gnu.org>
22411 * syssignal.h: Replace RETSIGTYPE with void.
22412 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
22413 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
22414 Replace SIGTYPE with void everywhere.
22415 * s/usg5-4-common.h (SIGTYPE): Remove definition.
22416 * s/template.h (SIGTYPE): Remove commented out definition.
22418 2011-03-26 Eli Zaretskii <eliz@gnu.org>
22420 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
22421 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
22423 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
22425 * w32.c (read_unc_volume): Use parameter `henum', instead of
22426 global variable `wget_enum_handle'.
22428 * keymap.c (describe_vector): Remove parameters `indices' and
22429 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.
22430 (describe_map, Fdescribe_vector): Adjust calls to `describe_vector'.
22432 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
22434 * keyboard.c (timer_check): Remove parameter `do_it_now',
22435 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
22436 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
22437 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
22439 * keyboard.c (read_char):
22440 * w32menu.c (w32_menu_display_help):
22441 * xmenu.c (show_help_event, menu_help_callback):
22442 Adjust calls to `show_help_echo'.
22444 * gtkutil.c (xg_maybe_add_timer):
22445 * keyboard.c (readable_events):
22446 * process.c (wait_reading_process_output):
22447 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
22449 * insdel.c (adjust_markers_gap_motion):
22450 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
22451 (gap_left, gap_right): Don't call it.
22453 2011-03-25 Chong Yidong <cyd@stupidchicken.com>

22497 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
22499 * w32term.c (x_set_glyph_string_clipping):
22500 Don't pass uninitialized region to CombineRgn.
22502 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
22504 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
22505 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
22506 (Fx_close_connection): Remove unused variable `i'.
22508 * w32font.c (w32font_draw): Return number of glyphs.
22509 (w32font_open_internal): Remove unused variable `i'.

22522 (uniscribe_font_driver): Add missing initializers.
22524 2011-03-23 Julien Danjou <julien@danjou.info>
22526 * term.c (Fsuspend_tty, Fresume_tty):
22527 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
22528 * window.c (temp_output_buffer_show):
22529 * insdel.c (signal_before_change):
22530 * frame.c (Fhandle_switch_frame):
22531 * fileio.c (Fdo_auto_save):
22532 * emacs.c (Fkill_emacs):
22533 * editfns.c (save_excursion_restore):
22534 * cmds.c (internal_self_insert):
22535 * callint.c (Fcall_interactively):
22536 * buffer.c (Fkill_all_local_variables):
22537 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22539 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22540 unconditionally since it does the check itself.
22542 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22544 Fix more problems found by GCC 4.5.2's static checks.
22546 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22547 the first time through the loop, since we know p0 < p1 then.
22548 This also avoids a gcc -Wstrict-overflow warning.
22550 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22551 leading to a memory leak, possible in functions like
22552 load_charset_map_from_file that can allocate an unbounded number
22553 of objects (Bug#8318).
22555 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22556 that could (at least in theory) be that large.
22558 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22559 This is less likely to overflow, and avoids undefined behavior if
22560 overflow does occur. All callers changed. Use strtoul to scan
22561 for the unsigned long integer.
22562 (pint2hrstr): Simplify and tune code slightly.
22563 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
22565 * scroll.c (do_scrolling): Work around GCC bug 48228.
22566 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
22568 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
22569 This also avoids a warning with gcc -Wstrict-overflow.
22570 (validate_x_resource_name): Simplify count usage.
22571 This also avoids a warning with gcc -Wstrict-overflow.
22573 * fileio.c (Fcopy_file): Report error if fchown or fchmod
22576 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
22578 * process.c (Fmake_network_process): Use socklen_t, not int,
22579 where POSIX says socklen_t is required in portable programs.
22580 This fixes a porting bug on hosts like 64-bit HP-UX, where
22581 socklen_t is wider than int (Bug#8277).
22582 (Fmake_network_process, server_accept_connection):
22583 (wait_reading_process_output, read_process_output):
22586 * process.c: Rename or move locals to avoid shadowing.
22587 (list_processes_1, Fmake_network_process):
22588 (read_process_output_error_handler, exec_sentinel_error_handler):
22589 Rename or move locals.
22590 (Fmake_network_process): Define label "retry_connect" only if needed.
22591 (Fnetwork_interface_info): Fix pointer signedness.
22592 (process_send_signal): Add cast to avoid pointer signedness problem.
22593 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
22594 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
22596 Make tparam.h and terminfo.c consistent.
22597 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22598 Include tparam.h instead, since it declares them.
22599 * cm.h (PC): Remove extern decl; tparam.h now does this.

22658 clobbering (Bug#8298).
22659 * sysdep.c (sys_subshell): Likewise.
22660 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22662 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22663 This should get cleaned up, so that child_setup has the
22664 same signature on all platforms.
22666 * callproc.c (call_process_cleanup): Now static.
22667 (relocate_fd): Rename locals to avoid shadowing.

22828 (Fmemory_limit): Cast sbrk's returned value to char *.
22830 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

22838 to use the following functions instead of these macros.
22839 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
22840 EMACS_INT, since callers assume the returned value fits in int.
22841 (upcase1): Likewise, for UPCASE_TABLE.
22842 (uppercasep, lowercasep, upcase): New static inline functions.
22843 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

22853 (regex_compile, re_match_2_internal): Mark locals as initialized.
22854 (RETALLOC_IF): Define only if needed.
22855 (WORDCHAR_P): Likewise. This one is never needed, but is used
22856 only in a comment talking about a compiler bug, so put inside
22857 the #if 0 of that comment.
22858 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22859 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

22886 New macros, so that the caller can use some names other than
22887 gcpro1, gcpro2, etc.
22888 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22890 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22891 argument, for consistency with GCPRO2_VAR, etc: it is now the
22892 prefix of the variable, not the variable itself. All uses
22894 * dired.c (directory_files_internal, file_name_completion):
22895 Rename locals to avoid shadowing.
22897 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22898 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22899 dired.c's scmp function, had undefined behavior.
22900 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22901 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22902 * buffer.h: ... to here, because these macros use current_buffer,
22903 and the new implementation with inline functions needs to have
22904 current_buffer in scope now, rather than later when the macros
22906 (downcase, upcase1): New static inline functions.
22907 (DOWNCASE, UPCASE1): Reimplement using these functions.
22908 This avoids undefined behavior in expressions like
22909 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22910 from race conditions in accessing the global variables
22911 case_temp1 and case_temp2.
22912 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22913 * lisp.h (case_temp1, case_temp2): Remove their decls.
22914 * character.h (ASCII_CHAR_P): Move from here ...
22915 * lisp.h: ... to here, so that the inline functions mentioned
22916 above can use them.

22923 (file_name_as_directory): Use const pointers when appropriate.
22924 (Fexpand_file_name): Likewise. In particular, newdir might
22925 point at constant storage, so make it a const pointer.

22927 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22929 (Fset_file_times, Finsert_file_contents, auto_save_error):

22936 * marker.c (bytepos_to_charpos): Remove; unused.
22938 * lisp.h (verify_bytepos, count_markers): New decls,
22939 so that gcc does not warn that these functions aren't declared.
22941 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22942 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22943 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22944 (copy_text): Remove unused local var.

22949 * buffer.c (fix_overlays_before): Mark locals as initialized.
22950 (fix_start_end_in_overlays): Likewise. This function should be
22951 simplified by using pointers-to-pointers, but that's a different
22953 (switch_to_buffer_1): Now static.
22954 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22955 (report_overlay_modification): Rename locals to avoid shadowing.

22960 to suppress a gcc -Wclobbered warning that does not seem to be right.
22961 (MAXPATHLEN): Define only if needed.
22963 * process.c (serial_open, serial_configure): Move decls from here ...
22964 * systty.h: ... to here, so that they can be checked.
22966 * fns.c (get_random, seed_random): Move extern decls from here ...
