34 and continuation glyphs alike.
35 (produce_special_glyphs) [HAVE_WINDOW_SYSTEM]: Produce a stretch
36 glyph of a suitably computed width, to align the special glyphs at
37 the window margin. Code moved from display_line. (Bug#11832)

262 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
263 * nsterm.m (ns_term_init):
264 Avoid the need for strncpy, by using build_string or
265 make_unibyte_string directly. Use dtoastr, not snprintf.
266 * process.c (Fmake_network_process): Diagnose service names that
267 are too long, rather than silently truncating them or creating
268 non-null-terminated names.

285 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
286 where argument type is known to be a Lisp_Cons.

460 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
461 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
462 Remove unused local.
463 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
464 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
465 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
466 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
467 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
468 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
469 Fix pointer signedness problem.
470 * xfaces.c (FRAME_X_FONT_TABLE):
471 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
473 2012-07-07 Glenn Morris <rgm@gnu.org>
475 * lread.c (load_path_check): New function, split from init_lread.
476 (init_lread): Reorganize. Motivation:
477 If EMACSLOADPATH is set, check/warn about that rather than the
478 defaults, which we are not going to use. Hence we can remove
479 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
480 Don't warn if site-lisp directories are missing.
481 If not installed, start from a blank load-path, since
482 PATH_LOADSEARCH refers to the eventual installation directories.
484 2012-07-07 Eli Zaretskii <eliz@gnu.org>
486 Support truncation and continuation glyphs on GUI frames, when
487 fringes are disabled. (Bug#11832)
488 * xdisp.c (init_iterator): Get dimensions of truncation and
489 continuation glyphs even if on GUI frames. Adjust
490 it->last_visible_x on GUI frames when the left or right fringes,
491 or both, are absent.
492 (start_display, move_it_in_display_line_to): Handle the case of a
493 GUI frame without a fringe to display continuation or truncation
494 glyphs.
495 (insert_left_trunc_glyphs): Support GUI frames: make sure
496 truncation glyphs overwrite enough glyphs from the current line to
497 have sufficient space in pixels.
498 (display_line): Support truncation and continuation glyphs on GUI
499 frames. If some spare pixels are left on the line after inserting
500 the truncation glyphs, fill that space with a stretch glyph of a
501 suitably computed width.
503 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
504 produce_glyphs, to support GUI sessions.
506 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
508 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
510 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
512 Do not require float-time's arg to fit in time_t (Bug#11825).
513 This works better on hosts where time_t is unsigned, and where
514 float-time is applied to the (negative) difference between two times.
515 * editfns.c (decode_time_components): Last arg is now double *,
516 not int *, and means to store all the result as a double, without
517 worrying about whether the seconds part fits in time_t.
518 All callers changed.
519 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
520 All callers changed.
521 (Ffloat_time): Do not fail merely because the specified time falls
522 outside of time_t range.
524 2012-07-07 Glenn Morris <rgm@gnu.org>
526 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

533 Update dependencies.
535 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
537 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
539 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
540 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
541 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
542 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
543 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
544 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
546 * xfont.c (compare_font_names): Redo to omit the need for casts.
548 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
550 * xfns.c (Fx_change_window_property): Doc fix.
551 * w32fns.c (Fx_change_window_property): Doc fix.
553 * w32fns.c (Fx_window_property): Accept the same arguments as the
554 X Windows version. Doc fix.
555 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
557 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
558 Eli Zaretskii <eliz@gnu.org>
560 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
561 Windows-specific code from nt/config.nt moved here.
562 Obsolete settings removed.
564 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
566 * process.c: Avoid unnecessary calls to gettime.
567 (wait_reading_process_output): Don't get the time of day
568 when gobbling data immediately and not waiting, as there's no need
569 for it in that case. This removes a FIXME.
571 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
573 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
574 is defined (Bug#11768).
576 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
578 Fix marker debugging code.
579 * marker.c (byte_char_debug_check): Do not perform the check
580 if buffer is not multibyte.
581 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
582 Call byte_char_debug_check with correct arguments.
584 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
586 Compile marker debugging code only if ENABLE_CHECKING is defined.
587 * marker.c (byte_char_debug_check, count_markers):
588 Use only if ENABLE_CHECKING is defined.
589 (byte_debug_flag): Remove.
590 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
591 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
593 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
595 Avoid code repetition in marker-related functions.
596 * marker.c (attach_marker): New function.
597 (Fset_marker, set_marker_restricted, set_marker_both)
598 (set_marker_restricted_both): Use it.
599 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
600 Consistently rename charno to charpos.
601 (marker_position): Add eassert.
602 (marker_byte_position): Convert to eassert.
604 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
606 Simplify list operations in unchain_overlay and unchain_marker.

615 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
616 * composite.c (autocmp_chars): Likewise.
617 * editfns.c (buildmark): Remove.
618 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
619 (save_restriction_save): Use build_marker.
620 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
621 * window.c (save_window_save): Likewise.
623 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
625 Do not use Fdelete_overlay in delete_all_overlays
626 to avoid redundant calls to unchain_overlay.
627 * buffer.c (drop_overlay): New function.
628 (delete_all_overlays, Fdelete_overlay): Use it.
629 * minibuf.c (get_minibuffer): Fix comment.
631 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
633 Port to OpenBSD 5.1 amd64.
634 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
635 This is needed for OpenBSD, and should be harmless on all BSD systems.
636 Also, include <sys/sysctl.h>, as it should be available on all
637 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
638 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
639 use p_pid member, not kp_proc.pid.
641 2012-07-06 Glenn Morris <rgm@gnu.org>
643 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
645 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
647 More xmalloc and related cleanup.
648 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

656 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
657 * xterm.c:
658 Omit needless casts involving void * pointers and allocation.
659 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
660 as the former is more robust if P's type is changed.
661 Prefer xzalloc to xmalloc + memset 0.
662 Simplify malloc-or-realloc to realloc.
663 Don't worry about xmalloc returning a null pointer.
664 Prefer xstrdup to xmalloc + strcpy.
665 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
666 growing it.
667 * keyboard.c (apply_modifiers_uncached): Prefer local array to
668 alloca of a constant.
670 2012-07-05 Eli Zaretskii <eliz@gnu.org>
672 * xdisp.c (display_line): Fix horizontal pixel coordinates when
673 hscroll is larger than the line width. Fixes long and futile
674 looping inside extend_face_to_end_of_line (on a TTY) producing
675 glyphs that are not needed and thrown away.
677 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
679 * marker.c (set_marker_restricted_both): Simplify by using
680 clip_to_bounds.
682 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
684 * editfns.c (region_limit): Simplify by using clip_to_bounds.

693 followed by gtk_box_set_homogeneous (Bug#11768).
694 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
695 (update_theme_scrollbar_width, xg_create_scroll_bar):
696 Use gtk_scrollbar_new (Bug#11768).
697 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
698 (is_box_type): New function (Bug#11768).
699 (xg_tool_item_stale_p): Call is_box_type.
700 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
701 with default display (Bug#11768).
703 2012-07-05 Eli Zaretskii <eliz@gnu.org>
705 * xdisp.c (window_hscroll_limited): New function.
706 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
707 coordinates when window's hscroll is set to insanely large
708 values. (Bug#11857)
710 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
712 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
713 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
715 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

774 Problem reported by Troels Nielsen in
775 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
777 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
779 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
780 This should be fixed in a better way; see Eli Zaretskii in
781 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
782 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
784 * fileio.c (time_error_value): Rename from special_mtime.
785 The old name's problems were noted by Eli Zaretskii in
786 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
788 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
789 This variable's comment says Emacs needs at least one GDB-visible
790 symbol of type enum pvec_type, to work around GDB problems.
791 The symbol's value doesn't matter.
793 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
794 that causes compilation to fail on pre-C99 compilers.
796 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
798 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

801 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
803 * buffer.c (init_buffer_once): Fix initialization of
804 headers for buffer_defaults and buffer_local_symbols.
805 Reported by Juanma Barranquero <lekktu@gmail.com>.
807 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
809 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
810 * lisp.h (enum pvec_type): Use fewer bits.
811 (PSEUDOVECTOR_SIZE_BITS): New constant.
812 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
813 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
814 change in pvec_type.
815 (PSEUDOVECTOR_TYPEP): New macro.

818 * emacs.c (gdb_pvec_type): Update type.
819 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
820 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
821 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
822 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
823 (sweep_vectors): Use it. Use local var `total_bytes' instead of
824 abusing vector->header.next.nbytes.
825 (live_vector_p): Use PVEC_TYPE.
826 (mark_object): Adapt code to extract pvectype. Use switch.
828 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
830 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
831 Tighten new eassert a bit.
833 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
835 Fix compilation with --enable-gcc-warnings and -O1
836 optimization level.
837 * doprnt.c (doprnt): Change type of tem to int, initialize
838 to avoid compiler warning. Add eassert.
839 * search.c (simple_search): Initialize match_byte to avoid
840 compiler warning. Add eassert.
842 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
844 Avoid weird behavior with large horizontal scrolls.
845 Without this change, for example, large hscroll values would
846 mess up Emacs's display on Fedora 15 x86, presumably due to
847 overflows in int calculations in the display code.
848 Also, if buffers had long lines, Emacs would freeze.
849 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
850 (set_window_hscroll): New function, containing the old guts of
851 Fset_window_hscroll. Return the clipped value.
852 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
853 This avoids the need to check against PTRDIFF_MAX.
855 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
857 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
859 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
861 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
863 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
864 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
865 since GCC 4.4.6 issues a bogus warning for them.
867 Fix bugs in file timestamp newness comparisons.
868 * fileio.c (Ffile_newer_than_file_p):
869 * lread.c (Fload): Use full timestamp resolution of files,
870 not just the 1-second resolution, so that files that are only
871 slightly newer still count as newer.
872 * fileio.c (Ffile_newer_than_file_p): Don't assume file
873 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
875 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
877 * fileio.c: Improve handling of file time marker. (Bug#11852)
878 (special_mtime): New function.
879 (Finsert_file_contents, Fverify_visited_file_modtime):
880 Use it to set special mtime values consistently.
882 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
884 * fileio.c (Finsert_file_contents): Properly handle st_mtime
885 marker for non-existing file. (Bug#11852)
887 2012-07-03 Glenn Morris <rgm@gnu.org>
889 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
890 and did not make it into globals.h).
892 2012-07-03 Tom Tromey <tromey@redhat.com>

932 * lisp.h (Frandom): Make it visible to C.
933 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
934 buffer for invisible buffers. (Bug#1229)
936 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
938 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
939 values which aren't power of 2.
940 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
941 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
942 accordingly.
944 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
946 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
948 * alloc.c (mark_object): Revert part of last patch to use `switch'.

952 * alloc.c (allocate_vector_block): Remove redundant
953 calls to mallopt if DOUG_LEA_MALLOC is defined.
954 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
955 avoid calls to mallopt if zero_vector is returned.
957 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
959 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
960 is enabled, avoid dereferencing NULL current_sblock if
961 running undumped.
963 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
965 Cleanup basic buffer management.
966 * buffer.h (struct buffer): Change layout to use generic vector
967 marking code. Fix some comments. Change type of 'clip_changed'
968 to bitfield. Remove unused #ifndef old.
969 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
970 (GET_OVERLAYS_AT): Fix indentation.
971 (for_each_per_buffer_object_at): New macro.

975 * alloc.c (allocate_buffer): Adjust to match new layout of
976 struct buffer. Fix comment.
977 (mark_overlay): New function.
978 (mark_buffer): Use it. Use mark_vectorlike to mark normal
979 Lisp area of struct buffer.
980 (mark_object): Use it. Adjust marking of misc objects
981 and related comments.
983 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
985 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
986 wrapper that is not needed because the wrapped code is a no-op (zero
987 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
988 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
990 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
992 * alloc.c (mark_buffer): Simplify. Remove prototype.
993 (mark_object): Add comment. Reorganize marking of vector-like
994 objects. Use CHECK_LIVE for all vector-like objects except buffers
995 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
996 redundant calls to mark_vectorlike for bool vectors.
998 2012-06-30 Glenn Morris <rgm@gnu.org>
1000 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
1002 * epaths.in (PATH_SITELOADSEARCH): New.
1003 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
1004 This is rather than relying on --enable-locallisppath elements
1005 having "site-lisp" in their names. (Bug#10208#25, 11658)
1007 2012-06-30 Eli Zaretskii <eliz@gnu.org>
1009 * w32proc.c (sys_select): Accept and ignore one more argument.
1011 * w32.c (emacs_gnutls_pull): Call select with one more argument.
1013 * sysselect.h [DOS_NT]: Don't include sys/select.h.
1014 (pselect) [!MS_DOS]: Redirect to sys_select.
1016 * sysdep.c: Don't include dos.h and dosfns.h.
1018 * process.c (sys_select):
1019 * msdos.c (sys_select): Accept one more argument and ignore it.
1021 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
1022 adapt data types and code to that.
1024 * dosfns.c:
1025 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
1026 which clashes with the gnulib function of the same name.
1028 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
1030 * font.c (font_style_to_value, font_style_symbolic)

1032 font_style_table.
1034 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
1035 argument.
1036 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
1037 uses.
1039 2012-06-29 Eli Zaretskii <eliz@gnu.org>
1041 * xdisp.c (try_window_id): Undo last change.
1043 * w32.c (getwd): Adjust commentary about startup_dir.
1044 (init_environment): Always call sys_access, even in non-MSVC
1045 builds. Don't chdir to the directory of the Emacs executable.
1046 This undoes code from 1997 which was justified by the need to
1047 "avoid conflicts when removing and renaming directories". But its
1048 downside was that every relative file name was being interpreted
1049 relative to the directory of the Emacs executable, which can never
1050 be TRT. In particular, it broke sys_access when called with
1051 relative file names.
1052 (sys_access): Map GetLastError to errno.
1054 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1056 * window.h (struct window): Change type of 'fringes_outside_margins'
1057 to bitfield. Fix comment. Adjust users accordingly.
1058 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
1059 Adjust comment.
1060 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
1061 to ptrdiff_t.
1063 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

1066 Add QUIT to make the loop interruptible.
1068 2012-06-29 Glenn Morris <rgm@gnu.org>
1070 * charset.c (init_charset): Make lack of etc/charsets fatal.
1072 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

1076 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1078 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
1079 undefined. Convert from xassert to eassert.
1080 * nsmenu.m: Convert from xassert to eassert.
1081 * nsterm.m: Likewise.
1083 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

1090 * window.c (HSCROLL_MAX): New macro.
1091 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
1092 overflow when requested scroll falls outside ptrdiff_t range.
1094 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
1096 * window.h (struct window): Change type of 'hscroll',
1097 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,

1099 Adjust users accordingly.
1100 * xdisp.c (try_cursor_movement): Replace type check with eassert.
1101 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
1102 from EMACS_INT to ptrdiff_t.

1168 purify-hashtable.
1170 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
1172 * alloc.c (allocate_string_data): Remove dead code.
1173 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
1174 avoid GCC warning about unused macro.
1176 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
1178 * alloc.c (allocate_string): Omit intervals initialization.
1179 * alloc.c (make_uninit_multibyte_string): Initialize intervals

1244 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
1246 Use sprintf return value instead of invoking strlen on result.
1247 In the old days this wasn't portable, since some sprintf
1248 implementations returned char *. But they died out years ago and
1249 Emacs already assumes sprintf returns int.
1250 Similarly for float_to_string.
1251 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
1252 * ccl.c (ccl_driver):

1258 * xfns.c (syms_of_xfns):
1259 Use sprintf or float_to_string result to avoid need to call strlen.
1260 * data.c (Fnumber_to_string):
1261 Use make_unibyte_string, since the string must be ASCII.
1262 * lisp.h, print.c (float_to_string): Now returns int length.
1263 * term.c (produce_glyphless_glyph):
1264 Use sprintf result rather than recomputing it.
1266 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
1267 * Makefile.in (ALL_CFLAGS):

1290 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>

1295 * xfns.c (x_window): Remove redundant cast.
1297 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
1299 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

1302 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
1304 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
1305 instead of truncating it to 63 (admittedly a generous limit).
1307 * process.c: Fix spelling and caps in comments.
1309 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
1311 * emacs.c (setpgrp): Remove definition, unused.

1323 * systime.h [WINDOWSNT]: Include sys/time.h.
1325 * s/ms-w32.h (struct timespec): Definition moved from
1326 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.

1358 Remove unnecessary forward decls.
1360 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

1369 when time_t is unsigned and as wide as intmax_t.
1370 See <http://bugs.gnu.org/9000#51>.
1372 2012-06-23 Eli Zaretskii <eliz@gnu.org>

1425 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
1427 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
1428 Privately reported by Herbert J. Skuhra.
1429 [__FreeBSD__]: Remove "*/" typo after "#include".
1430 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
1431 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
1432 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
1433 Don't assume EMACS_TIME and struct timeval are the same type.
1435 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
1437 Support higher-resolution time stamps (Bug#9000).
1438 The time stamps are only nanosecond-resolution at the C level,
1439 since that's the best that any real-world system supports now.
1440 But they are picosecond-resolution at the Lisp level, as that's
1441 easy, and leaves room for future OS improvements.
1443 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
1444 (LIBES): Use it.
1446 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
1447 Don't get current time unless it's needed.
1449 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
1450 now provides it if it's absent.
1451 (start_atimer): Port to higher-res time stamps.
1452 Check for time stamp overflow. Don't get current time more
1453 often than is needed.
1455 * buffer.h (struct buffer): Buffer modtime now has high resolution.
1456 Include systime.h, not time.h.
1457 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
1459 * dired.c: Include stat-time.h.
1460 (Ffile-attributes): File times now have higher resolution.
1462 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
1463 (struct image): Timestamp now has higher resolution.
1465 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
1466 has at least microseconds now. All uses removed.
1467 (update_frame, update_single_window, update_window, update_frame_1)
1468 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
1470 * editfns.c (time_overflow): Now extern.
1471 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)

1477 (make_time): Now static.
1478 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
1479 Report an error if the time is invalid, rather than having the caller
1480 do that.
1482 * fileio.c: Include <stat-time.h>
1483 (Fcopy_file): Copy higher-resolution time stamps.
1484 Prefer to set the time stamp via a file descriptor if that works.

1486 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
1487 (Fvisited_file_modtime, Fset_visited_file_modtime):
1488 Support higher-resolution time stamps.
1490 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
1492 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
1494 * image.c (prepare_image_for_display, clear_image_cache)
1495 (lookup_image): Port to higer-resolution time stamps.
1497 * keyboard.c (start_polling, bind_polling_period):
1498 Check for time stamp overflow.
1499 (read_char, kbd_buffer_get_event, timer_start_idle)
1500 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
1501 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
1502 Port to higher-resolution time stamps. Do not assume time_t is signed.
1503 (decode_timer): New function. Timers are now vectors of length 9,
1504 not 8, to accommodate the picosecond component.
1505 (timer_check_2): Use it.
1507 * nsterm.m (select_timeout, timeval_subtract): Remove.
1508 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
1509 as they're a bit more accurate and handle overflow better.
1510 (ns_select): Change prototype to be compatible with pselect.
1511 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
1512 * nsterm.h (ns_select): Adjust prototype.
1514 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
1515 us-resolution time stamps.
1516 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
1518 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
1520 * lisp.h (time_overflow): New decl.
1521 (wait_reading_process_output): First arg is now intmax_t, not int,
1522 to accommodate larger waits.
1524 * process.h (struct Lisp_Process.read_output_delay):
1525 Now counts nanoseconds, not microseconds.
1526 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
1527 EMACS_HAS_USECS.
1528 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
1529 (wait_reading_process_output):
1530 Port to ns-resolution time stamps.
1531 (Faccept_process_output, wait_reading_process_output):
1532 Check for time stamp overflow. Do not assume time_t is signed.
1533 (select_wrapper): Remove; we now use pselect.
1534 (Fprocess_attributes): Now generates ns-resolution time stamps.
1536 * sysdep.c: Include utimens.h. Don't include utime.h
1537 or worry about struct utimbuf; gnulib does that for us now.
1538 (gettimeofday): Remove; gnulib provides a substitute.
1539 (make_timeval): New function.
1540 (set_file_times): Now sets ns-resolution time stamps.
1541 New arg FD; all uses changed.
1542 (time_from_jiffies, ltime_from_jiffies, get_up_time)
1543 (system_process_attributes):
1544 Now returns ns-resolution time stamp. All uses changed.
1545 Check for time stamp overflow.
1547 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
1548 provides a substitute now.
1550 * systime.h: Include timespec.h rather than sys/time.h and time.h,
1551 since it guarantees struct timespec.
1552 (EMACS_TIME): Now struct timespec, so that we can support
1553 ns-resolution time stamps.
1554 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
1555 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
1556 (EMACS_USECS): Remove.
1557 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
1558 so multiply the arg by 1000 before storing it.
1559 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
1560 New macros.
1561 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
1562 Port to ns-resolution time stamps.
1563 (EMACS_TIME_NEG_P): Remove; replaced by....

1568 (make_timeval, make_lisp_time, decode_time_components): New decls.
1569 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
1570 that it mishandled time_t overflow. You can't compare by subtracting!
1571 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
1572 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
1574 * term.c: Include <sys/time.h>.
1575 (timeval_to_Time): New function, for proper overflow wraparound.
1576 (term_mouse_position, term_mouse_click): Use it.
1578 * undo.c (record_first_change): Support higher-resolution time stamps
1579 in the undo buffer.
1580 (Fprimitive_undo): Use them when restoring time stamps.
1582 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
1583 (w32_get_internal_run_time):
1584 Port to higher-resolution Emacs time stamps.
1585 (ltime): Now accepts single 64-bit integer, as that's more convenient
1586 for callers.
1588 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
1590 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
1591 for compatibility with pselect. Support ns-resolution time stamps.
1593 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
1595 * xselect.c (wait_for_property_change, x_get_foreign_selection):
1596 Check for time stamp overflow, and support ns-resolution time stamps.
1598 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
1599 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
1600 (timeval_subtract): Remove; no longer needed.
1601 (XTflash, XTring_bell, x_wait_for_event):
1602 Port to ns-resolution time stamps. Don't assume time_t is signed.

1608 2012-06-22 Eli Zaretskii <eliz@gnu.org>
1610 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
1611 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
1612 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
1613 staticidx goes up to 1597 out of 1600 = 0x640.)
1615 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
1617 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
1618 Otherwise, the umask might be mistakenly 0 while handling input signals.
1620 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
1622 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

1628 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
1629 access to `contents' member of Lisp_Vector objects with AREF and ASET
1630 where appropriate.
1632 2012-06-19 Chong Yidong <cyd@gnu.org>
1634 * frame.c (delete_frame): When selecting a frame on a different
1635 text terminal, do not alter the terminal's top-frame.

1638 frame's selected window and its terminal's top-frame.
1639 (unwind_format_mode_line): Restore them.
1640 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
1641 Callers changed.
1642 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
1643 since tty frames can be explicitly named.
1644 (prepare_menu_bars): Likewise.
1646 * term.c (Ftty_top_frame): New function.
1648 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

1651 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
1652 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
1653 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
1654 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
1655 (METER_1, METER_2): Simplify.
1657 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
1659 * data.c (Fdefalias): Return `symbol' (bug#11686).
1661 2012-06-18 Martin Rudalics <rudalics@gmx.at>
1663 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
1664 gets killed during executing of this function (Bug#11665).
1665 Try to always return Qt when the buffer has been actually killed.
1666 (Vkill_buffer_query_functions): In doc-string say that functions
1667 run by this hook should not change the current buffer.
1669 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
1671 Fix recently-introduced process.c problems found by static checking.
1672 * process.c (write_queue_push, write_queue_pop, send_process):

1675 (send_process): Remove unused local.
1677 2012-06-17 Chong Yidong <cyd@gnu.org>

1689 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
1691 * lisp.h (eassert): Assume C89 or later.
1692 This removes the need for CHECK.
1693 (CHECK): Remove. Its comments about always evaluating its
1694 argument were confusing, as 'eassert' typically does not evaluate
1695 its argument.
1697 * coding.c (produce_chars): Use ptrdiff_t, not int.
1699 * xterm.c (x_draw_underwave): Check for integer overflow.
1700 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

1794 If all the glyphs of the glyph row came from strings, and we have no
1795 cursor positioning clues, put the cursor on the first glyph of the
1796 row.

1869 * s/gnu.h (POSIX_SIGNALS): Remove (not used since 2010-05-04).
1871 2012-06-13 Paul Eggert <eggert@cs.ucla.edu>
1873 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
1874 * alloc.c (make_number) [!defined make_number]:
1875 Remove, as lisp.h always defines this now.
1876 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
1877 (roundup_size): Verify that it is a power of 2.
1878 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
1879 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
1880 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
1881 -DUSE_LSB_TAG=0, to override the automatically-selected default.
1882 USE_LSB_TAG now is always defined to be either 0 or 1.
1883 All uses changed.
1884 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
1885 code works fine either way, and efficiency is not a concern here,
1886 as the union type is for debugging, not for production.
1887 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
1888 Use an inline function on all platforms when using the union type,
1889 since this is simpler and 'static inline' can be used portably
1890 within Emacs now.
1891 (LISP_INITIALLY_ZERO): New macro.
1892 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
1893 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.
1895 2012-06-12 Glenn Morris <rgm@gnu.org>

1915 * image.c (imagemagick_load_image): Remove unused label.
1917 2012-06-11 Glenn Morris <rgm@gnu.org>

1920 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
1921 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
1922 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.

1930 2012-06-11 Chong Yidong <cyd@gnu.org>
1932 * image.c (imagemagick_load_image): Implement transparency.
1934 2012-06-10 Andreas Schwab <schwab@linux-m68k.org>
1936 * regex.c (at_begline_loc_p): Also recognize `(?N:' and correctly

1961 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
1962 dbus_type_is_basic if available.
1963 (xd_extract_signed, xd_extract_unsigned): Rename from
1964 extract_signed and extract_unsigned, respectively. Adapt callers.
1966 2012-06-09 Chong Yidong <cyd@gnu.org>

1971 case (Bug#9752).
1973 2012-06-08 Paul Eggert <eggert@cs.ucla.edu>
1975 * xdisp.c (vmessage): Treat frame message as multibyte.
1976 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
1977 would generate the diagnostic "Making \302\247 buffer-local while
1978 let-bound!".
1980 2012-06-08 Eli Zaretskii <eliz@gnu.org>
1982 * dispnew.c (showing_window_margins_p): Undo last change, which
1983 was done due to an inadvertent commit.
1984 (adjust_frame_glyphs_for_frame_redisplay): Do call
1985 showing_window_margins_p.
1987 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>

1993 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
1995 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
1996 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
1998 2012-06-08 Eli Zaretskii <eliz@gnu.org>
2000 * alloc.c (allocate_vectorlike): Fix last change.
2002 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
2004 Block-based vector allocation of small vectors.
2005 * lisp.h (struct vectorlike_header): New field `nbytes',
2006 adjust comment accordingly.
2007 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
2008 to denote vector blocks. Adjust users (live_vector_p,
2009 mark_maybe_pointer, valid_lisp_object_p) accordingly.
2010 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
2011 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),

2024 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
2025 (init_alloc_once): Add call to init_vectors.
2027 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
2029 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
2031 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
2033 * doprnt.c (doprnt): Truncate multibyte char correctly.
2034 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
2035 would mishandle a string argument "Xc" if X was a multibyte
2036 character of length 2: it would truncate after X's first byte
2037 rather than including all of X.
2039 2012-06-06 Chong Yidong <cyd@gnu.org>
2041 * buffer.c (word_wrap): Doc fix.
2043 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

2055 binary via PaX flags if the paxctl utility is available.
2056 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):

2067 (note_mode_line_or_margin_highlight): If there is no help echo,
2068 use mode-line-default-help-echo. Handle the case where the mouse
2069 position is past the end of the mode line string.
2071 * buffer.c (buffer_local_value_1): New function, split from
2072 Fbuffer_local_value; can return Qunbound.
2073 (Fbuffer_local_value): Use it.
2074 (Vmode_line_format): Docstring tweaks.
2076 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>

2088 * minibuf.c (Fassoc_string): Remove duplicate declaration.
2090 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
2091 Convert pctcpu and pctmem to Lisp float properly.
2092 Let the compiler fold better, as 100.0/0x8000 is exact.
2094 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
2096 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
2097 cons_block.
2099 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
2101 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
2103 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
2105 For a 'struct window', replace some Lisp_Object fields to
2106 bitfields where appropriate, remove unused fields.
2107 * window.h (struct window): Remove unused 'last_mark_x' and
2108 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
2109 change it's type from Lisp_Object to bitfield.
2110 Change type of 'force_start', 'optional_new_start',
2111 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
2112 fields from Lisp_Object to bitfield. Adjust users accordingly.
2114 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2116 Pacify gcc -Wdouble-precision when using Xaw.
2117 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
2118 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
2119 Use 'float' consistently, rather than 'float' in most places
2120 and 'double' in a couple of places.
2122 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2124 * xdisp.c (handle_stop): Detect whether we have overlay strings
2125 loaded by testing it->current.overlay_string_index to be
2126 non-negative, instead of checking whether n_overlay_strings is
2127 positive. (Bug#11587)
2129 2012-05-31 Chong Yidong <cyd@gnu.org>
2131 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
2133 * doc.c (Fsubstitute_command_keys): Doc fix.
2135 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2137 * search.c (search_buffer): Remove calls to
2138 r_alloc_inhibit_buffer_relocation, as it is now called by
2139 maybe_unify_char, which was the cause of relocation of buffer text
2140 in bug#11519.
2142 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2144 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
2145 for the duration of call to load_charset, to avoid problems with
2146 callers of maybe_unify_char that access buffer text through C
2147 pointers.
2149 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
2150 decrement the inhibition flag, instead of just setting or
2151 resetting it.
2153 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2155 Remove obsolete '#define static' cruft.
2156 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
2157 This #undef was "temporary" in 2000; it is no longer needed
2158 now that '#define static' has gone away.
2159 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
2160 (gray_bitmap_bits): Remove; no longer needed.
2161 All uses replaced with definiens.
2162 * xterm.c: Include "bitmaps/gray.xbm".
2164 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
2166 Clean up __executable_start, monstartup when --enable-profiling.
2167 The following changes affect the code only when profiling.
2168 * dispnew.c (__executable_start): Rename from safe_bcopy.
2169 Define only on platforms that need it.
2170 * emacs.c: Include <sys/gmon.h> when profiling.
2171 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
2172 (__executable_start): Remove decl, since lisp.h does it now.
2173 (safe_bcopy): Remove decl; no longer has that name.
2174 (main): Coalesce #if into single bit of code, for simplicity.
2175 Cast pointers to uintptr_t, since standard libraries want integers
2176 and not pointers.
2177 * lisp.h (__executable_start): New decl.
2179 2012-05-31 Glenn Morris <rgm@gnu.org>
2181 * image.c (Fimagemagick_types): Doc fix.

2200 * lread.c (read1): Tiny simplification.
2202 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
2204 Do not create empty overlays with the evaporate property (Bug#9642).
2205 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
2206 Bug#9642, but explicitly check that the buffer the overlay would
2207 be moved to is live and rearrange lines to make sure that errors
2208 will not put the overlay in an inconsistent state.
2209 (Fdelete_overlay): Cosmetics.
2211 2012-05-28 Eli Zaretskii <eliz@gnu.org>
2213 * w32term.c (my_bring_window_to_top): New function.
2214 (x_raise_frame): Use handle returned by DeferWindowPos, which
2215 could be different from the original one.
2216 Call my_bring_window_to_top instead of my_set_foreground_window.
2217 (Bug#11513)
2219 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
2220 by calling BringWindowToTop.

2225 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
2227 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
2228 This avoids undefined behavior that might cause the eassert
2229 to not catch an out-of-range value.
2231 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
2233 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

2245 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
2247 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
2248 Only r_alloc_inhibit_buffer_relocation needed to be added;
2249 the others were already declared.
2251 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
2252 before checking whether it's out of range. Put the check inside
2253 eassert. See
2254 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
2256 2012-05-27 Ken Brown <kbrown@cornell.edu>
2258 * callproc.c (Fcall_process): Restore a line that was accidentally
2259 commented out in the 2011-02-13 change (bug#11547).

2263 * lisp.h [REL_ALLOC]: Add prototypes for external functions
2264 defined on ralloc.c.
2266 * buffer.c [REL_ALLOC]: Remove prototypes of
2267 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
2268 they are now on lisp.h.
2270 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
2272 * search.c (search_buffer): Use it to inhibit relocation of buffer
2273 text while re_search_2 is doing its job, because re_search_2 is
2274 passed C pointers to buffer text. (Bug#11519)
2276 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
2277 Update value to 24.
2279 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
2280 state after an additional call to move_it_in_display_line_to, keep
2281 the values of it->max_ascent and it->max_descent found for the
2282 entire line.
2283 (pos_visible_p): Revert the comparison against bottom_y to what it
2284 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
2285 (Bug#11464)
2287 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
2289 Fix coding-related core dumps with gcc -ftrapv.
2290 The code was computing A - B, where A and B are pointers, and B is
2291 random garbage. This can lead to core dumps on platforms that
2292 have special pointer registers, and it also leads to core dumps on
2293 x86-64 when compiled with gcc -ftrapv. The fix is to compute
2294 A - B only when B is initialized properly.
2295 * coding.c (coding_set_source, coding_set_destination): Return void.
2296 (coding_change_source, coding_change_destinations): New functions,
2297 with the old behaviors of coding_set_source and coding_set_destination.
2298 All callers that need an offset changed to use these new functions.
2300 2012-05-26 Glenn Morris <rgm@gnu.org>
2302 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)

2307 * xdisp.c (draw_row_with_mouse_face):
2308 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
2310 * w32console.c: Include window.h.
2311 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
2312 New functions.
2313 (initialize_w32_display): Initialize mouse-highlight data.
2315 * w32inevt.c: Include termchar.h and window.h.
2316 (do_mouse_event): Support mouse-autoselect-window. When the mouse
2317 moves, call note_mouse_highlight. If help_echo changed, call
2318 gen_help_event to produce help-echo message in the echo area.
2319 Call clear_mouse_face if mouse_face_hidden is set in the mouse
2320 highlight info.
2322 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
2324 * lread.c (read1): Simplify slightly to avoid an overflow warning
2325 with GCC 4.7.0 on x86-64.
2327 2012-05-26 Eli Zaretskii <eliz@gnu.org>
2329 * bidi.c (bidi_mirror_char): Revert last change: an int is
2330 definitely wide enough here.
2332 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
2334 Fix integer width and related bugs (Bug#9874).
2335 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):

2344 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2345 (allocate_pseudovector):
2346 Use int, not EMACS_INT, where int is wide enough.
2347 (inhibit_garbage_collection, Fgarbage_collect):
2348 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2349 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
2350 int might not be wide enough.

2366 (Foverlay_recenter, last_overlay_modification_hooks_used)
2367 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
2368 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2369 (validate_region): Omit unnecessary test for b <= e,
2370 since that's guaranteed by the previous test.
2371 (adjust_overlays_for_delete): Avoid pos + length overflow.
2372 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
2373 (report_overlay_modification):
2374 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2375 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
2376 Omit pointer cast, which isn't needed anyway, and doesn't work
2377 after the EMACS_INT -> ptrdiff_t change.
2378 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
2379 * buffer.h: Adjust decls to match defn changes elsewhere.

2384 not int, to avoid needless 32-bit limit on 64-bit hosts.
2385 (exec_byte_code): Use tighter memory-full test, one that checks
2386 for alloca overflow. Don't compute the address of the object just
2387 before an array, as that's not portable. Use EMACS_INT, not
2388 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
2389 * callint.c (Fcall_interactively):
2390 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2391 * callproc.c (call_process_kill, Fcall_process):
2392 Don't assume pid_t fits into an Emacs fixnum.

2401 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
2402 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2403 (casify_object): Avoid integer overflow when overallocating buffer.
2404 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
2405 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
2406 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
2407 * category.h (CATEGORYP): Don't assume arg is nonnegative.
2408 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
2409 integers are now checked earlier. All uses replaced with XINT.
2410 (ccl_driver):
2411 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2412 For CCL_MapSingle, check that content and value are in int range.

2414 Check that Vcode_version_map_vector is a vector.
2415 (resolve_symbol_ccl_program): Check that vector header is in range.
2416 Always copy the vector, so that we can check its contents reliably
2417 now rather than having to recheck each instruction as it's being
2418 executed. Check that vector words fit in 'int'.
2419 (ccl_get_compiled_code, Fregister_ccl_program)
2420 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
2421 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
2422 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
2423 contents are in range.
2424 (Fccl_execute_on_string): Check that status is in range.
2425 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
2426 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
2427 Accept and return EMACS_INT, not int, because callers can pass values
2428 out of 'int' range.
2429 (c_string_width, strwidth, lisp_string_width, chars_in_text)
2430 (multibyte_chars_in_text, parse_str_as_multibyte)

2433 (string_escape_byte8, Fget_byte):
2434 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2435 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
2436 avoid mishandling large integers.
2437 * character.h: Adjust decls to match defn changes elsewhere.
2438 * charset.c (load_charset_map_from_file, find_charsets_in_text)

2443 Don't assume fixnum fits in int.
2444 (load_charset_map_from_vector, Fmap_charset_chars):

2446 (Fdefine_charset_internal): Check ranges here, more carefully.
2447 Don't rely on undefined behavior with signed left shift overflow.
2448 Don't assume unsigned int fits into fixnum, or that fixnum fits
2449 into unsigned int. Don't require max_code to be a valid fixnum;
2450 that's not true for gb10830 4-byte on a 32-bit host. Allow
2451 invalid_code to be a cons, for the same reason. Require code_offset
2452 to be a character. Avoid int overflow if max_char is close
2453 to INT_MAX.
2454 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
2455 this is intended anyway and avoids some undefined behavior.
2456 (load_charset_map): Pass unsigned, not int, as 2nd arg of
2457 INDEX_TO_CODE_POINT, as that's what it expects.
2458 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
2459 * charset.h (DECODE_CHAR): Return int, not unsigned;
2460 this is what was intended anyway, and it avoids undefined behavior.
2461 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
2462 integer-overflow issues.
2463 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
2464 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
2465 where the argument is EMACS_INT, and this behavior is not intended.
2466 * chartab.c (Fmake_char_table, Fset_char_table_range)
2467 (uniprop_get_decoder, uniprop_get_encoder):
2468 Don't assume fixnum fits in int.
2469 * cmds.c (move_point): New function, that does the gist of
2470 Fforward_char and Fbackward_char, but does so while checking
2471 for integer overflow more accurately.
2472 (Fforward_char, Fbackward_char): Use it.
2473 (Fforward_line, Fend_of_line, internal_self_insert)
2474 (internal_self_insert):
2475 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2476 Fix a FIXME, by checking for integer overflow when calculating
2477 target_clm and actual_clm.

3122 * xterm.c (x_x_to_emacs_modifiers):

3124 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
3125 may come from Lisp.
3126 (handle_one_xevent): NATNUMP can eval its arg twice.

3130 (struct scroll_bar): Use struct vectorlike_header
3131 rather than rolling our own approximation.
3132 (SCROLL_BAR_VEC_SIZE): Remove; not used.
3134 2012-05-25 Glenn Morris <rgm@gnu.org>
3136 * lisp.mk (lisp): Update for more files being compiled now.
3138 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
3140 * lread.c: Remove `read_pure' which makes no difference.
3141 (read_pure): Remove var.
3142 (unreadpure): Remove function.
3143 (readevalloop): Don't call read_list with -1 flag.
3144 (read1, read_vector): Don't test read_pure any more.
3145 (read_list): Simplify.

3155 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
3156 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
3158 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
3160 Remove src/m/*.
3161 This directory predates autoconf and is no longer needed nowadays.
3162 Move its few remaining bits of functionality to where they're needed.
3163 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
3164 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
3165 * m/template.h: Remove.
3166 * Makefile.in (M_FILE): Remove. All uses removed.
3167 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
3168 * lisp.h (USE_LSB_TAG):
3169 * mem-limits.h (EXCEEDS_LISP_PTR):
3170 Use VAL_MAX, not VALBITS, in #if.
3171 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
3172 (EMACS_UINT): Define unconditionally now.
3173 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
3174 (BITS_PER_EMACS_INT): New constants, replacing
3175 what used to be in config.h, but not useful in #if.
3176 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
3177 define them any more.
3178 (VAL_MAX): New macro.
3179 (VALMASK): Use it.
3180 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
3181 BITS_PER_EMACS_INT, in #if.
3182 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
3183 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
3184 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
3185 * s/ms-w32.h (DATA_START):
3186 Move here from removed file m/intel386.h.
3187 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
3188 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
3190 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
3192 Assume C89 or later.
3193 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
3194 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)

3202 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
3203 * xterm.c (input_signal_count): Assume volatile works.
3205 2012-05-21 Ken Brown <kbrown@cornell.edu>
3207 * xgselect.c (xg_select): Fix first argument in call to 'select'
3208 (bug#11508).
3210 2012-05-20 Ken Brown <kbrown@cornell.edu>
3212 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
3213 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
3215 2012-05-19 Ken Brown <kbrown@cornell.edu>
3217 * xfns.c (x_in_use): Remove `static' qualifier.
3218 * xterm.h (x_in_use): Declare.
3219 * xgselect.c: Include xterm.h.
3220 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
3221 and `display_arg' (bug#9754).
3223 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
3225 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
3227 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
3228 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
3230 2012-05-18 Eli Zaretskii <eliz@gnu.org>
3232 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
3234 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
3235 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
3237 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
3238 reference to image_cache->refcount.
3239 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
3241 2012-05-17 Juri Linkov <juri@jurta.org>
3243 * search.c (Fword_search_regexp, Fword_search_backward)
3244 (Fword_search_forward, Fword_search_backward_lax)
3245 (Fword_search_forward_lax): Move functions to isearch.el
3246 (bug#10145, bug#11381).
3248 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
3250 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
3252 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
3254 * lread.c (init_obarray): Declare Qt and Qnil as special.
3256 2012-05-14 Glenn Morris <rgm@gnu.org>
3258 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
3259 Put "libexec" before "bin", for the sake of init_callproc_1.
3261 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3263 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
3265 * unexaix.c: Port to more-recent AIX compilers.
3266 (report_error, report_error_1, make_hdr, copy_sym)
3267 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
3268 Make arguments const char *, not char *, to avoid violations of C
3269 standard and to fix some AIX warnings reported by Gilles Pion.
3271 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3273 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
3274 already have overlays loaded.
3275 (handle_single_display_spec): Before returning without displaying
3276 fringe bitmap, synchronize the bidi iterator with the main display
3277 iterator, by calling iterate_out_of_display_property.
3278 (iterate_out_of_display_property): Detect buffer iteration by
3279 testing that it->string is a Lisp string.
3280 (get_next_display_element): When the current object is exhausted,
3281 and there's something on it->stack, call set_iterator_to_next to
3282 proceed with what's on the stack, instead of returning zero.
3283 (set_iterator_to_next): If called at the end of a Lisp string,
3284 proceed to consider_string_end without incrementing string
3285 position. Don't increment display vector index past the end of
3286 the display vector. (Bug#11417)
3287 (pos_visible_p): Don't report a position visible when move_it_to
3288 stopped at the last line of window, which happens to be scanned
3289 backwards by the bidi iteration. (Bug#11464)
3291 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3293 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
3294 and right-margin display specs even if the spec is invalid or we
3295 are on a TTY, and thus unable to display on the fringes.
3296 That's because the text with the property will not be displayed anyway,
3297 so we need to signal to the caller that this is a "replacing"
3298 display spec. This fixes display when the spec is invalid or we
3299 are on a TTY.
3301 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3303 * unexaix.c (make_hdr): Fix typo in prototype.
3304 This bug broke the build on AIX. Problem reported by Gilles Pion.
3306 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
3308 * keyboard.c (kbd_buffer_get_event): Read special events also in
3309 batch mode. (Bug#11415)
3311 2012-05-12 Glenn Morris <rgm@gnu.org>
3313 * ns.mk: Update for ns_appbindir no longer having trailing "/".
3315 2012-05-12 Eli Zaretskii <eliz@gnu.org>
3317 * lisp.mk (lisp): Add newcomment.elc.
3319 2012-05-12 Glenn Morris <rgm@gnu.org>
3321 * Makefile.in (MKDIR_P): New, set by configure.
3322 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
3324 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
3326 Remove unused function hourglass_started.
3327 * dispextern.h (hourglass_started):
3328 * w32fns.c (hourglass_started):
3329 * xdisp.c (hourglass_started): Remove.
3331 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
3333 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
3334 Update dependencies.
3336 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
3338 * xgselect.c (xg_select): Put maxfds+1 into a var.
3339 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
3341 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
3343 2012-05-10 Dave Abrahams <dave@boostpro.com>
3345 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
3346 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
3348 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
3350 * dbusbind.c (xd_registered_buses): New internal Lisp object.
3351 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
3352 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
3353 Initialize xd_registered_buses.
3355 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
3357 Untag more efficiently if USE_LSB_TAG.
3358 This is based on a proposal by YAMAMOTO Mitsuharu in
3359 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
3360 For an admittedly artificial (nth 8000 longlist) benchmark on
3361 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
3362 Emacs's overall text size by 1%.
3363 * lisp.h (XUNTAG): New macro.
3364 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
3365 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
3366 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
3367 * eval.c (Fautoload):
3368 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
3369 * frame.h (XFRAME): Use XUNTAG.
3371 Port recent dbusbind.c changes to 32-bit --with-wide-int.
3372 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
3373 Remove unportable assumptions about print widths of types like
3374 dbus_uint32_t.
3375 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
3376 intptr_t when converting between pointer and integer, to avoid GCC
3377 warnings about wrong width.
3379 2012-05-09 Eli Zaretskii <eliz@gnu.org>
3381 * w32proc.c (new_child): Force Windows to reserve only 64KB of
3382 stack for each reader_thread, instead of defaulting to 8MB
3383 determined by the linker. This avoids failures in creating
3384 subprocesses on Windows 7, see the discussion in this thread:
3385 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
3387 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
3389 Fix up display of the *Minibuf-0* buffer in the mini window.
3390 * keyboard.c (read_char): Don't clear the echo area if there's no
3391 message to clear.
3392 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
3393 contents of *Minibuf-0*) if there's no message displayed in its stead.
3395 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
3397 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
3398 batch mode.
3400 2012-05-06 Chong Yidong <cyd@gnu.org>
3402 * lisp.mk (lisp): Update.
3404 2012-05-05 Jim Meyering <meyering@redhat.com>
3406 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
3408 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
3410 * data.c (PUT_ERROR): New macro.
3411 (syms_of_data): Use it. Add new error type `user-error'.
3412 * undo.c (user_error): New function.
3413 (Fprimitive_undo): Use it.
3414 * print.c (print_error_message): Adjust print style for `user-error'.
3415 * keyboard.c (user_error): New function.
3416 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
3418 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
3420 Do not limit current-time-string to years 1000..9999.
3421 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
3422 (Fcurrent_time_string): Support any year that is supported by the
3423 underlying localtime representation. Don't use asctime, as it
3424 has undefined behavior for years outside the range -999..9999.

3428 Fix race conditions involving setenv, gmtime, localtime, asctime.
3429 Without this fix, interrupts could mess up code that uses these
3430 nonreentrant functions, since setting TZ invalidates existing
3431 tm_zone or tzname values, and since most of these functions return
3432 pointers to static storage.
3433 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
3434 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
3435 Grow the critical sections to include not just invoking
3436 localtime/gmtime, but also accessing these functions' results
3437 including their tm_zone values if any, and any related TZ setting.
3438 (format_time_string): Last arg is now struct tm *, not struct tm **,
3439 so that the struct tm is saved in the critical section.
3440 All callers changed. Simplify allocation of initial buffer, partly
3441 motivated by the fact that memory allocation needs to be outside
3442 the critical section.
3444 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
3446 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
3447 with RESET_INTERVAL.
3449 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
3450 Remove duplicated buffer name initialization.
3452 2012-05-02 Jim Meyering <jim@meyering.net>
3454 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
3456 * xfns.c (x_window): Use xstrdup (Bug#11375).
3458 2012-05-02 Eli Zaretskii <eliz@gnu.org>
3460 * xdisp.c (pos_visible_p): If already at a newline from the
3461 display string before the 'while' loop, don't walk back the glyphs
3462 from it3.glyph_row. Solves assertion violation when the display
3463 string begins with a newline (egg.el). (Bug#11367)
3465 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
3467 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
3468 Move to simple.el.
3470 2012-05-01 Glenn Morris <rgm@gnu.org>
3472 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
3473 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
3474 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
3475 All were removed before 23.1.
3477 * dispnew.c: Remove HAVE_LIBNCURSES test;
3478 it is always true on relevant platforms.
3480 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
3481 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
3483 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
3485 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
3487 * .gdbinit (xpr): Remove checks for no longer existing misc types.
3488 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
3489 Remove.
3491 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
3493 Do not avoid creating empty evaporating overlays (Bug#9642).
3494 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
3495 That is, do not delete an evaporating overlay if it becomes
3496 empty after its bounds are adjusted to fit within its buffer.
3497 This fix caused other problems, and I'm reverting it until we get
3498 to the bottom of them.
3500 2012-04-27 Chong Yidong <cyd@gnu.org>
3502 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
3504 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3506 * xdisp.c (pos_visible_p): If the window start position is beyond
3507 ZV, start the display from buffer beginning. Prevents assertion
3508 violation in init_iterator when the minibuffer window is scrolled
3509 via the scroll bar.
3511 * window.c (window_scroll_pixel_based): Likewise.
3513 2012-04-27 Chong Yidong <cyd@gnu.org>
3515 * keymap.c (where_is_internal): Doc fix (Bug#10872).
3517 2012-04-27 Glenn Morris <rgm@gnu.org>
3519 * fileio.c (Fcopy_file, Fset_file_selinux_context):
3520 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
3522 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3524 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
3525 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
3527 2012-04-26 Eli Zaretskii <eliz@gnu.org>
3529 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
3530 display element, check also the underlying string or buffer
3531 character. (Bug#11341)
3533 * w32menu.c: Include w32heap.h.
3534 (add_menu_item): If the call to AppendMenuW (via
3535 unicode_append_menu) fails, disable Unicode menus only if we are
3536 running on Windows 9X/Me.
3538 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
3540 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
3541 (xgetint): Add missing shift for LSB tags.
3543 2012-04-24 Martin Rudalics <rudalics@gmx.at>
3545 * keyboard.c (read_char): Don't wipe echo area for select window
3546 events: These might get delayed via `mouse-autoselect-window'
3547 (Bug#11304).
3549 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
3551 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
3552 manipulation of :loaded-from data.
3554 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
3556 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
3557 now a cons (bug#11311).
3559 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
3561 Do not create empty overlays with the evaporate property (Bug#9642).
3562 * buffer.c (Fmove_overlay): Delete an evaporating overlay
3563 if it becomes empty after its bounds are adjusted to fit within
3564 its buffer. Without this fix, in a nonempty buffer (let ((o
3565 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
3566 yields an empty overlay that has the evaporate property, which is
3567 not supposed to happen.
3569 Fix minor GTK3 problems found by static checking.
3570 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
3571 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
3572 (struct _EmacsFixedClass, emacs_fixed_get_type):

3580 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
3581 (EMACS_FIXED_GET_CLASS): Remove; unused.
3582 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.

3585 Problem reported by Juanma Barranquero for Windows -Wunused-function.
3587 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
3589 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
3590 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
3591 (__malloc_size_t, __malloc_ptrdiff_t):
3592 Remove. All uses removed, replaced by the definiens if needed,
3593 since we can assume C89 or better now.
3594 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

3603 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
3604 Define using prototypes, not old style.
3605 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
3606 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.

3684 * sysdep.c [__FreeBSD__]: Minor cleanups.
3685 (list_system_processes, system_process_attributes) [__FreeBSD__]:
3686 Use Emacs indenting style more consistently. Avoid some casts.

3706 is nil.
3707 (print_object): Check for cycles even when print-circle is nil and
3708 print-gensym is t, but only check print_depth if print-circle is nil.
3710 2012-04-20 Chong Yidong <cyd@gnu.org>
3712 * process.c (wait_reading_process_output): If EIO occurs on a pty,
3713 set the status to "failed" and ensure that sentinel is run.
3715 2012-04-20 Glenn Morris <rgm@gnu.org>

3770 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
3771 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

3784 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
3785 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
3786 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
3787 [REL_ALLOC]: ... to here, to check interface.
3788 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:

3812 Remove definition of GC_MARK_STACK, since the default now works.
3813 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
3814 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
3815 no longer the default.
3816 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
3818 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
3820 * lread.c (lisp_file_lexically_bound_p):

3841 2012-04-11 Daniel Colascione <dancol@dancol.org>
3843 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
3844 against is gone. It's better to use vfork now so that when Cygwin
3845 gains a new, working vfork, we use it automatically (bug#10398).
3847 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

3872 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
3873 not just in the obarray, before snarfing them. (Bug#11036)
3875 * Makefile.in ($(leimdir)/leim-list.el):
3876 Pass EMACS rather than BUILT_EMACS.
3878 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
3880 * process.c (make_process):
3881 * process.h: Add integer `gnutls_handshakes_tried' member to
3882 process struct.
3884 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
3885 Add convenience `GNUTLS_LOG2i' macro.
3887 * gnutls.c (gnutls_log_function2i): Convenience log function.
3888 (emacs_gnutls_read): Use new log functions,
3889 `gnutls_handshakes_tried' process member, and
3890 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
3891 attempts per process (connection).
3893 2012-04-09 Chong Yidong <cyd@gnu.org>
3895 * eval.c (Fuser_variable_p, user_variable_p_eh)
3896 (lisp_indirect_variable): Functions deleted.
3897 (Fdefvar): Caller changed.
3899 * callint.c (Finteractive, Fcall_interactively):
3900 * minibuf.c (Fread_variable): Callers changed.
3902 2012-04-09 Eli Zaretskii <eliz@gnu.org>
3904 * xdisp.c (set_cursor_from_row): If the display string appears in
3905 the buffer at position that is closer to point than the position
3906 after the display string, display the cursor on the first glyph of
3907 the display string. Fixes cursor display when a 'display' text
3908 property immediately follows invisible text. (Bug#11094)
3910 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
3912 composite.c: use 'double' consistently
3913 * composite.c (get_composition_id): Use 'double' consistently
3914 instead of converting 'float' to 'double' and vice versa; this is
3915 easier to understand and avoids a GCC warning.
3917 2012-04-09 Glenn Morris <rgm@gnu.org>
3919 * Makefile.in: Generate leim-list with bootstrap-emacs, in
3920 preparation for dumping it with emacs. (Bug#4789)
3921 (leimdir): New variable.
3922 ($(leimdir)/leim-list.el): New rule.
3923 (emacs$(EXEEXT)): Depend on leim-list.el.

3936 * xml.c (init_libxml2_functions) [WINDOWSNT]:
3937 Remove unused local variable.
3939 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
3941 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
3942 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
3943 (mark_memory): Mark Lisp_Objects only if pointers might hide in
3944 objects, as mark_maybe_pointer will catch them otherwise.
3945 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
3946 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
3948 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
3950 Fix typo that broke non-Windows builds.
3951 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
3953 2012-04-07 Eli Zaretskii <eliz@gnu.org>
3955 Support building on MS-Windows with libxml2.
3957 * makefile.w32-in (OBJ2): Add xml.$(O).
3958 (GLOBAL_SOURCES): Add xml.c.
3959 ($(BLD)/xml.$(O)): New dependency list.
3961 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
3962 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
3963 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
3964 [!WINDOWSNT]: New macros.
3965 (init_libxml2_functions, libxml2_loaded_p): New functions.
3966 (parse_region): Call fn_xmlCheckVersion instead of using the macro
3967 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
3968 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
3969 Calls xmlCleanupParser only if libxml2 was loaded (or statically
3970 linked in).
3971 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
3972 Call init_libxml2_functions before calling libxml2 functions.
3973 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
3975 * emacs.c: Don't include libxml/parser.h.
3976 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
3977 xmlCleanupParser directly.
3979 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
3981 2012-04-07 Eli Zaretskii <eliz@gnu.org>
3983 * indent.c (Fvertical_motion): If there is a display string at
3984 point, use it.vpos to compute how many lines to backtrack after
3985 move_it_to point. (Bug#11133)
3987 2012-04-06 Eli Zaretskii <eliz@gnu.org>
3989 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
3990 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
3991 about subtle differences between FETCH_CHAR* and STRING_CHAR*
3992 macros related to unification of CJK characters. For the details,
3993 see the discussion following the message here:
3994 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
3996 2012-04-04 Chong Yidong <cyd@gnu.org>
3998 * keyboard.c (Vdelayed_warnings_list): Doc fix.
4000 2012-04-01 Eli Zaretskii <eliz@gnu.org>
4002 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
4003 instead of alloca. (Bug#11138)
4005 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
4007 * w32menu.c (is_simple_dialog): Properly check lisp types.
4008 (Bug#11141)
4010 2012-03-31 Eli Zaretskii <eliz@gnu.org>
4012 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
4013 position we get to after a call to move_it_to fails the
4014 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
4015 only if we wind up in a string from display property. (Bug#11063)
4017 * window.c (Fdelete_other_windows_internal): Invalidate the row
4018 and column information about mouse highlight, so that redisplay
4019 restores it after reallocating the glyph matrices. (Bug#7464)
4021 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
4022 string comes from a `display' text property, use the buffer
4023 position of that property as if we actually saw that position in
4024 the row's glyphs.
4025 (move_it_by_lines): Remove the assertion that
4026 "it->current_x == 0 && it->hpos == 0" which can be legitimately
4027 violated when there's a before-string at the beginning of a line.
4028 (Bug#11063)
4030 2012-03-30 Eli Zaretskii <eliz@gnu.org>
4032 * xdisp.c (append_space_for_newline): If the default face was
4033 remapped, use the remapped face for the appended newline.
4034 (extend_face_to_end_of_line): Use the remapped default face for
4035 extending the face to the end of the line.
4036 (display_line): Call extend_face_to_end_of_line when the default
4037 face was remapped. (Bug#11068)
4039 2012-03-29 Eli Zaretskii <eliz@gnu.org>
4041 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
4043 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
4045 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
4047 2012-03-27 Glenn Morris <rgm@gnu.org>
4049 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
4050 Doc fixes.
4052 2012-03-26 Kenichi Handa <handa@m17n.org>
4054 * dispextern.h (struct glyph): Fix previous change. Change the
4055 bit length of glyphless.ch to 25 (Bug#11082).
4057 2012-03-26 Chong Yidong <cyd@gnu.org>
4059 * keyboard.c (Vselection_inhibit_update_commands): New variable.
4060 (command_loop_1): Use it; inhibit selection update for
4061 handle-select-window too (Bug#8996).
4063 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
4065 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
4067 2012-03-25 Kenichi Handa <handa@m17n.org>
4069 * dispextern.h (struct glyph): Change the bit length of
4070 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
4072 2012-03-24 Eli Zaretskii <eliz@gnu.org>
4074 * s/ms-w32.h (tzname): Include time.h before redirecting to
4075 _tzname. Fixes the MSVC build. (Bug#9960)
4077 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
4079 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
4080 characters.
4082 * xterm.c (XTread_socket): Only modify handling_signal if
4083 !SYNC_INPUT. (Bug#11080)
4085 2012-03-23 Eli Zaretskii <eliz@gnu.org>
4087 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
4088 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
4089 when fetching a multibyte character consumes more bytes than
4090 CHAR_BYTES returns, due to unification of CJK characters in
4091 string_char. (Bug#11073)
4093 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
4095 * process.c (wait_reading_process_output): Handle pty disconnect
4096 by refraining from sending oneself a SIGCHLD (bug#10933).
4098 2012-03-22 Chong Yidong <cyd@gnu.org>
4100 * dispextern.h (struct it): New member string_from_prefix_prop_p.
4102 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
4103 Mark string as coming from a prefix property.
4104 (handle_face_prop): Use default face for prefix strings (Bug#4281).
4105 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
4107 2012-03-21 Chong Yidong <cyd@gnu.org>
4109 * xfaces.c (Vface_remapping_alist): Doc fix.
4111 2012-03-20 Eli Zaretskii <eliz@gnu.org>
4113 * w32proc.c (Fw32_set_console_codepage)
4114 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
4115 Doc fixes.
4117 2012-03-20 Chong Yidong <cyd@gnu.org>
4119 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
4120 to reflect default non-nil value of redisplay-dont-pause.
4122 2012-03-19 Kenichi Handa <handa@m17n.org>
4124 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
4125 it fit in a valid range (Bug#11003).
4127 2012-03-18 Eli Zaretskii <eliz@gnu.org>
4129 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
4130 that is not from display property, accept the row as a "cursor
4131 row" if one of the string's character has a non-nil `cursor'
4132 property. Fixes cursor positioning when there are newlines in
4133 overlay strings, e.g. in icomplete.el. (Bug#11035)
4135 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
4137 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
4139 2012-03-12 Chong Yidong <cyd@gnu.org>
4141 * eval.c (inhibit_lisp_code): Rename from
4142 inhibit_window_configuration_change_hook; move from window.c.
4144 * xfns.c (unwind_create_frame_1, Fx_create_frame):
4145 * window.c (run_window_configuration_change_hook)
4146 (syms_of_window): Callers changed.
4148 2012-03-11 Chong Yidong <cyd@gnu.org>
4150 * keymap.c (Fkey_description): Doc fix (Bug#9700).

4156 * frame.c (other_visible_frames): Don't assume the selected frame
4157 is visible (Bug#10955).
4159 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
4161 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
4163 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
4165 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
4166 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
4167 zero (Bug#10954).
4169 2012-03-03 Glenn Morris <rgm@gnu.org>
4171 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
4173 2012-03-02 Eli Zaretskii <eliz@gnu.org>
4175 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
4176 position past the first glyph_row that ends at ZV. (Bug#10902)
4177 (redisplay_window, next_element_from_string): Fix typos in
4178 comments.
4179 (redisplay_window): Pass to move_it_vertically the margin in
4180 pixels, not in screen lines.
4182 2012-03-02 Glenn Morris <rgm@gnu.org>
4184 * buffer.c (buffer-list-update-hook): Doc fix.
4186 2012-02-29 Eli Zaretskii <eliz@gnu.org>
4188 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
4189 push_it before setting up the iterator for the first overlay
4190 string, even if we have an empty string loaded.
4191 (next_overlay_string): If there's an empty string on the iterator
4192 stack, pop the stack. (Bug#10903)
4194 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
4196 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
4197 Suggested by Stefan Monnier in
4198 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
4199 * alloc.c (widen_to_Lisp_Object): New static function.
4200 (mark_memory): Also mark Lisp_Objects by fetching pointer words
4201 and widening them to Lisp_Objects. This would work even if
4202 USE_LSB_TAG is defined and wide integers are used, which might
4203 happen in a future version of Emacs.
4205 2012-02-25 Chong Yidong <cyd@gnu.org>
4207 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
4208 Doc fix.
4210 * xselect.c (Fx_selection_exists_p): Doc fix.
4211 (x_clipboard_manager_save_all): Print an informative message
4212 before saving to clipboard manager.
4214 2012-02-24 Chong Yidong <cyd@gnu.org>
4216 * keyboard.c (process_special_events): Handle all X selection
4217 requests in kbd_buffer, not just the next one (Bug#8869).
4219 2012-02-23 Chong Yidong <cyd@gnu.org>
4221 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
4222 call when setting menu-bar-lines and tool-bar-lines parameters.
4223 (unwind_create_frame_1): New helper function.
4225 * window.c (inhibit_window_configuration_change_hook): New var.
4226 (run_window_configuration_change_hook): Obey it.
4227 (syms_of_window): Initialize it.
4229 2012-02-22 Chong Yidong <cyd@gnu.org>
4231 * xterm.c (x_draw_image_relief): Add missing type check for
4232 Vtool_bar_button_margin (Bug#10743).
4234 2012-02-21 Chong Yidong <cyd@gnu.org>
4236 * fileio.c (Vfile_name_handler_alist): Doc fix.
4238 * buffer.c (Fget_file_buffer): Protect against invalid file
4239 handler return value.
4241 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
4243 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
4244 when computing $valmask.
4246 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
4247 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
4248 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
4249 It's useless in that case, and it can cause problems on hosts
4250 that allocate halves of EMACS_INT values separately.
4251 Reported by Dan Horák. Diagnosed by Andreas Schwab in
4252 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
4253 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
4254 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
4255 it avoids undefined behavior on hosts where shifting right by more
4256 than the word width has undefined behavior.
4258 2012-02-19 Chong Yidong <cyd@gnu.org>
4260 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
4261 (Funhandled_file_name_directory, Ffile_name_as_directory)
4262 (Fdirectory_file_name, Fexpand_file_name)
4263 (Fsubstitute_in_file_name): Protect against invalid file handler
4264 return values (Bug#10845).
4266 2012-02-18 Eli Zaretskii <eliz@gnu.org>
4268 * .gdbinit (pitx): Fix incorrect references to fields of the
4269 iterator stack.
4271 2012-02-17 Chong Yidong <cyd@gnu.org>
4273 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
4275 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
4277 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
4278 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
4280 2012-02-15 Chong Yidong <cyd@gnu.org>
4282 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
4283 marked as special. Also, starting docstrings with * is obsolete.
4285 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
4287 * gnutls.c (emacs_gnutls_write): Fix last change.
4289 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
4291 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
4292 send_process.
4294 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
4296 * keymap.c (Fsingle_key_description): Handle char ranges.
4298 2012-02-12 Chong Yidong <cyd@gnu.org>
4300 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
4301 as that creates a dangerous corner case.
4303 * window.c (Fdelete_window_internal): Invalidate the mouse
4304 highlight (Bug#9904).
4306 2012-02-12 Glenn Morris <rgm@gnu.org>
4308 * xselect.c (Fx_own_selection_internal)
4309 (Fx_get_selection_internal, Fx_disown_selection_internal)
4310 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
4311 * nsselect.m (Fx_own_selection_internal)
4312 (Fx_disown_selection_internal, Fx_selection_exists_p)
4313 (Fx_selection_owner_p, Fx_get_selection_internal):
4314 Sync docs and argument specs with the xselect.c versions.
4316 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
4318 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
4320 2012-02-11 Eli Zaretskii <eliz@gnu.org>
4322 * w32select.c (Fx_selection_exists_p): Sync doc string and
4323 argument list with xselect.c. (Bug#10783)
4325 * w16select.c (Fx_selection_exists_p): Sync doc string and
4326 argument list with xselect.c. (Bug#10783)
4328 2012-02-10 Glenn Morris <rgm@gnu.org>
4330 * fns.c (Fsecure_hash): Doc fix.
4332 2012-02-09 Kenichi Handa <handa@m17n.org>

4336 2012-02-07 Chong Yidong <cyd@gnu.org>
4338 * buffer.c (Fbuffer_local_variables)
4339 (buffer_lisp_local_variables): Handle unbound vars correctly;
4340 don't let Qunbound leak into Lisp.
4342 2012-02-07 Glenn Morris <rgm@gnu.org>
4344 * image.c (Fimagemagick_types): Doc fix.
4346 * image.c (imagemagick-render-type): Change it from a lisp object
4347 to an integer. Move the doc here from the lisp manual.
4348 Treat all values not equal to 0 the same.
4350 2012-02-06 Chong Yidong <cyd@gnu.org>
4352 * doc.c (store_function_docstring): Avoid applying docstring of
4353 alias to base function (Bug#2603).
4355 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
4357 * .gdbinit (pp1, pv1): Remove redundant defines.

4855 (Fword_search_backward_lax, Fword_search_forward_lax):
4856 Use `Fword_search_regexp' instead of `wordify'. Doc fix.
4857 (syms_of_search): Define `Sword_search_regexp'. (Bug#10145)
4859 2011-12-01 Stefan Monnier <monnier@iro.umontreal.ca>
4861 * fileio.c (Finsert_file_contents): Move after-change-function call
4862 to before the "handled:" label, since all "goto handled" appear in
4863 cases where the *-change-functions have already been properly called
4864 (bug#10117).
4866 2011-12-01 Andreas Schwab <schwab@linux-m68k.org>
4868 * keyboard.c (interrupt_signal): Don't call kill-emacs when
4869 waiting for input. (Bug#10169)

4873 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
4874 verifies glyph row's hash code--we have just reallocated the
4875 glyphs, so their contents can be complete garbage. (Bug#10164)

4893 (get_current_wm_state): Set net_wm_state_hidden_seen to 1 if
4894 _NET_WM_STATE_HIDDEN is in NET_WM_STATE.
4896 2011-11-28 Paul Eggert <eggert@cs.ucla.edu>

4908 * dispnew.c (scrolling_window): Truncate overlaps in copy destination
4909 of scroll runs so as to avoid assigning disabled bogus rows and
4910 unnecessary graphics copy operations.
4912 2011-11-27 Eli Zaretskii <eliz@gnu.org>
4914 * s/ms-w32.h (utimbuf) [_MSC_VER]: Don't define.
4915 (snprintf) [_MSC_VER]: Redirect to _snprintf.
4916 (strtoll) [_MSC_VER]: Redirect to _strtoi64.
4917 (malloc, free, realloc, calloc): Redirect to e_* only when
4918 compiling Emacs.
4920 * lisp.h (GCTYPEBITS): Move before first use.
4921 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
4922 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
4923 this macro definition.
4925 * s/ms-w32.h (tzname): Redirect to _tzname for all values of
4926 _MSC_VER.
4928 2011-11-27 Jan Djärv <jan.h.d@swipnet.se>

4936 * fileio.c (Finsert_file_contents): Undo previous change; see
4937 <http://lists.gnu.org/archive/html/emacs-diffs/2011-11/msg00265.html>.
4939 2011-11-26 Paul Eggert <eggert@cs.ucla.edu>

4946 Indent for consistency with usual Emacs style.
4948 2011-11-25 Eli Zaretskii <eliz@gnu.org>
4950 * xdisp.c (redisplay_window): If cursor row is not fully visible
4951 after recentering, and scroll-conservatively is set to a large
4952 number, scroll window by a few more lines to make the cursor fully
4953 visible and out of scroll-margin. (Bug#10105)
4954 (start_display): Don't move to the next line if the display should
4955 start at a newline that is part of a display vector or an overlay
4956 string. (Bug#10119)
4958 2011-11-24 Juri Linkov <juri@jurta.org>

4983 * dispnew.c (adjust_glyph_matrix): Don't verify hash code of mode-
4984 and header-lines, as they don't have one computed for them.
4985 (Bug#10098)
4987 * .gdbinit (prow): Make displayed values more self-explaining.

5033 2011-11-20 Paul Eggert <eggert@cs.ucla.edu>
5035 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
5036 Otherwise, valgrind does not work on some platforms.
5037 Problem reported by Andreas Schwab in
5038 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
5039 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
5040 is set, removing the need for VIRT_ADDRESS_VARIES.
5041 (PURE_P): Use a more-efficient implementation that needs just one
5042 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
5043 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
5044 to 4 (xorl, subq, cmpq, setbe).
5045 * alloc.c (pure): Always extern now, since that's the
5046 VIRT_ADDR_VARIES behavior.
5047 (PURE_POINTER_P): Use a single comparison, not two, for
5048 consistency with the new puresize.h.
5049 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
5050 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
5051 Remove VIRT_ADDR_VARIES no longer needed.

5056 (erase_phys_cursor, update_window_cursor, show_mouse_face)
5057 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
5058 behave as if the cursor position were at the window margin.
5060 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
5061 and the cursor position is out of bounds, behave as if the cursor
5062 position were at the window margin. (Bug#10075)
5064 2011-11-18 Chong Yidong <cyd@gnu.org>
5066 * window.c (Fwindow_combination_limit): Make first argument
5067 non-optional, since it is meaningless for live windows like the
5068 selected window.

5081 * dispnew.c (swap_glyph_pointers): Swap the used[] arrays and the
5082 hash values of the two rows.
5083 (copy_row_except_pointers): Preserve the used[] arrays and the
5084 hash values of the two rows. (Bug#10035)
5085 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
5087 * xdisp.c (row_hash): New function, body extracted from
5088 compute_line_metrics.
5089 (compute_line_metrics): Call row_hash, instead of computing the
5090 hash code inline.
5092 * dispnew.c (verify_row_hash): Call row_hash for computing the
5093 hash code of a row, instead of duplicating code from xdisp.c.
5095 * dispextern.h (row_hash): Add prototype.
5097 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
5099 * frame.c (delete_frame): Don't delete the terminal when the last

5122 (Fset_window_nest): Rename to Fset_window_combination_limit.
5123 (Vwindow_nest): Rename to Vwindow_combination_limit.
5124 (recombine_windows, make_parent_window, make_window)
5125 (Fsplit_window_internal, saved_window)
5126 (Fset_window_configuration, save_window_save): Rename all
5127 occurrences of window_nest to window_combination_limit.
5129 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
5131 * image.c (imagemagick_load_image): Fix typo.
5133 2011-11-14 Eli Zaretskii <eliz@gnu.org>
5135 * xdisp.c (display_line): Move the call to
5136 highlight_trailing_whitespace before the call to
5137 compute_line_metrics, since the latter needs to see the final
5138 faces of all the glyphs to compute ROW's hash value.
5139 Fixes assertion violations in row_equal_p. (Bug#10035)
5141 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
5143 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
5144 just return (bug#10044).
5146 2011-11-12 Eli Zaretskii <eliz@gnu.org>
5148 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
5149 with user-defined heap size. Bump the default size of the temacs
5150 heap to 27MB, to avoid memory warning when running temacs.
5151 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
5153 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
5154 current_matrix and desired_matrix. (Bug#9990)
5155 (verify_row_hash) [XASSERTS]: New function.
5156 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
5157 that the hash value of glyph rows is correct.

5184 process_coding.
5186 2011-11-11 Johan Bockgård <bojohan@gnu.org>
5188 * xdisp.c (fill_composite_glyph_string): Always set s->face, to
5189 avoid a crash (bug#9496).
5191 2011-11-09 Chong Yidong <cyd@gnu.org>
5193 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

5200 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
5202 Avoid some portability problems by eschewing 'extern inline' functions.
5203 The trivial performance wins aren't worth the portability hassles; see
5204 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
5205 et seq.
5206 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
5207 (window_box_width, window_box_left, window_box_left_offset)
5208 (window_box_right, window_box_right_offset): Undo previous change,
5209 by removing the "extern"s.
5210 * intervals.c (adjust_intervals_for_insertion)
5211 (adjust_intervals_for_deletion): Undo previous change,
5212 making these static again.
5213 (offset_intervals, temp_set_point_both, temp_set_point)
5214 (copy_intervals_to_string): No longer inline.
5215 * xdisp.c (window_text_bottom_y, window_box_width)

5254 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
5255 This is also needed for porting to any host where GC_MARK_STACK is
5256 not GC_MAKE_GCPROS_NOOPS.
5257 (which_symbols): Use it.
5259 2011-11-07 Kenichi Handa <handa@m17n.org>

5272 * xmenu.c (cleanup_widget_value_tree): New function.
5273 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
5274 calling free_menubar_widget_value_tree directly (Bug#9830).
5276 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
5278 Fix some portability problems with 'inline'.
5279 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
5280 (window_box_width, window_box_left, window_box_left_offset)
5281 (window_box_right, window_box_right_offset): Declare extern.
5282 Otherwise, these inline functions do not conform to C99 and
5283 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
5284 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
5285 * intervals.c (adjust_intervals_for_insertion)
5286 (adjust_intervals_for_deletion): Now extern, because otherwise the
5287 extern inline functions 'offset_intervals' couldn't refer to it.
5288 (static_offset_intervals): Remove.
5289 (offset_intervals): Rewrite using the old contents of
5290 static_offset_intervals. The old version didn't conform to C99
5291 because an extern inline function contained a reference to an
5292 identifier with static linkage.
5294 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
5296 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

5313 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
5314 (Fwindow_vscroll): Doc fix.
5315 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
5316 argument, since it makes no sense to pass a live window and for
5317 consistency with window-child.

5398 * xdisp.c (note_mouse_highlight): If either of
5399 previous/next-single-property-change returns nil, treat that as
5400 the beginning or the end of the buffer. (Bug#9955)
5402 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>

5428 Rename cover_string to disp_string.
5430 2011-11-01 Martin Rudalics <rudalics@gmx.at>
5432 * window.c (temp_output_buffer_show): Don't use

5487 2011-10-29 Glenn Morris <rgm@gnu.org>
5489 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
5490 Not clear what it was for, and it causes various bugs. (Bug#9839)
5492 2011-10-28 Eli Zaretskii <eliz@gnu.org>
5494 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
5495 possible random value that matches one of those tested as
5496 condition to clear the mouse face.
5498 2011-10-28 Chong Yidong <cyd@gnu.org>
5500 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.

5514 2011-10-28 Eli Zaretskii <eliz@gnu.org>
5516 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
5517 <oslsachem@gmail.com> for helping to debug this.

5525 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
5526 New functions.
5527 (w32font_open_internal, compute_metrics):
5528 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
5529 instead of calling the "wide" APIs directly.
5531 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
5533 * w32.h (syms_of_w32font): Add prototype.
5535 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
5537 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
5538 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
5539 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
5540 (Fmove_to_window_line): Doc fix.
5542 2011-10-27 Chong Yidong <cyd@gnu.org>
5544 * process.c (make_process): Set gnutls_state to NULL.
5546 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
5547 non-NULL, regardless of GNUTLS_INITSTAGE.
5548 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
5549 an error. Set process slots as soon as we allocate them.

5572 extracted from Fw32_default_color_map.
5573 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
5575 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
5577 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
5579 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
5581 * keyboard.c (test_undefined): New function (bug#9751).
5582 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
5584 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
5586 * sysdep.c (init_sys_modes): Fix the check for the controlling
5587 terminal (Bug#6649).
5589 2011-10-20 Eli Zaretskii <eliz@gnu.org>
5591 * dispextern.h (struct bidi_it): New member next_en_type.
5593 * bidi.c (bidi_line_init): Initialize the next_en_type member.
5594 (bidi_resolve_explicit_1): When next_en_pos is valid for the
5595 current character, check also for next_en_type being WEAK_EN.
5596 (bidi_resolve_weak): Don't enter the expensive loop if the current
5597 position is before next_en_pos. Record the bidi type of the first
5598 non-ET, non-BN character we find, in addition to its position.
5599 (bidi_level_of_next_char): Invalidate next_en_type when
5600 next_en_pos is over-stepped.
5602 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
5604 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
5605 * editfns.c: Rewrite current-time-zone so that it invokes
5606 the equivalent of (format-time-string "%Z") to get the time zone name.
5607 This fixes a bug when the time zone name contains characters that
5608 need converting from the system time locale to Emacs internal format.
5609 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
5610 that patch fixed format-time-string to do the conversion, but
5611 I forgot to fix current-time-zone.
5612 (format_time_string): New function, containing most of
5613 what Fformat_time_string used to contain.
5614 (Fformat_time_string): Rewrite in terms of format_time_string.
5615 This doesn't change this function's behavior.
5616 (current-time-zone): Rewrite to use format_time_string.
5617 This fixes the bug reported by Michael Schierl in
5618 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
5619 Jason Rumney's 2007-06-07 change worked around this bug, but
5620 didn't fix it.
5621 * systime.h (tzname, timezone): Remove no-longer-used declarations.
5623 2011-10-19 Eli Zaretskii <eliz@gnu.org>
5625 * xdisp.c (start_display): If the character at POS is displayed
5626 via a display vector, reset IT->current.dpvec_index to zero.
5627 (try_window_reusing_current_matrix): If a line ends in a display
5628 vector or the next line starts in a display vector, continue
5629 redrawing the window even though the character position of
5630 start_row was reached.
5631 (Bug#9771, part 2)
5633 2011-10-18 Chong Yidong <cyd@gnu.org>
5635 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
5636 with nobreak-char-display too.
5638 2011-10-18 Eli Zaretskii <eliz@gnu.org>
5640 Fix part 3 of bug#9771.
5641 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
5642 (bidi_resolve_neutral): Don't enter the expensive loop looking for
5643 non-neutral characters if the current character is a paragraph
5644 separator (a.k.a. Newline). This avoids running the same
5645 expensive loop twice, once when we consume the preceding newline
5646 and the other time when the line actually needs to be displayed.
5647 Avoid the loop when we see neutrals on the base embedding level
5648 following a character whose directionality is the same as the
5649 paragraph's. This avoids running the expensive loop when a line
5650 ends in a long sequence of neutrals, like control characters.
5651 Add assertion against STRONG_AL type. Slightly rearrange code
5652 that determines the type of a neutral given the first non-neutral
5653 that follows it.
5654 (bidi_level_of_next_char): Set next_en_pos to zero when
5655 invalidating its info.
5657 2011-10-17 Eli Zaretskii <eliz@gnu.org>
5659 * xdisp.c (push_display_prop): Determine whether to record string
5660 or buffer position by IT->string, not by IT->method. Allow
5661 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
5662 (move_it_vertically_backward): Don't look for character position
5663 immediately after the newline when in a continuation line.
5664 (Bug#9771, part 1)
5666 2011-10-15 Martin Rudalics <rudalics@gmx.at>
5668 * window.c (coordinates_in_window): Rewrite and delabelize
5669 vertical border check. (Bug#5357) (Bug#9618)
5671 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
5673 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
5674 errors in XSetWindowBorder (bug#9310).
5676 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
5678 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
5679 avoid crash when xmalloc overrun checking is enabled.
5681 2011-10-13 Eli Zaretskii <eliz@gnu.org>
5683 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
5684 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
5685 cursor motion with <left> and <right> arrow keys.
5687 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
5688 some callers set that themselves.
5690 2011-10-12 Eli Zaretskii <eliz@gnu.org>
5692 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
5693 display string and the previous row comes from the same string and
5694 is empty. (Bug#9739) (Bug#9738)
5696 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
5698 * doc.c (get_doc_string): Encode file name (bug#9735).
5700 2011-10-12 Eli Zaretskii <eliz@gnu.org>
5702 * bidi.c (bidi_level_of_next_char):
5703 * xdisp.c (get_visually_first_element): Remove old incorrect
5704 comments regarding the Unicode Line Separator character.
5706 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
5708 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
5710 * alloc.c (Fgc_status): Do not access beyond zombies array
5711 boundary if nzombies > MAX_ZOMBIES.
5712 * alloc.c (dump_zombies): Add missing format specifier.
5714 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
5716 * xdisp.c (set_cursor_from_row): Simplify conditionals,
5717 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
5719 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
5720 Some packages use them to denote characters with modifiers.
5722 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
5724 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
5725 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
5726 matching a pp-number. Rename parameter var to var1.
5728 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
5730 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
5732 2011-10-08 Glenn Morris <rgm@gnu.org>
5734 * callint.c (Fcall_interactively): Give a more explicit error for the
5735 'c' case with a non-character input. (Bug#8479)
5737 2011-10-08 Eli Zaretskii <eliz@gnu.org>
5739 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
5740 lines.
5741 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
5742 lines that are hscrolled on the left.
5744 * dispnew.c (buffer_posn_from_coords): Account for a possible
5745 presence of header-line. (Bug#4426)
5747 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
5749 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
5750 Don't advertise functionality which we discourage or doesn't work.
5752 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
5754 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
5755 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
5756 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
5757 this makes Emacs dump core during garbage collection on rare
5758 occasions. sizeof is obviously inferior to offsetof here, so
5759 stick with offsetof.
5760 (GC_POINTER_ALIGNMENT): New macro.
5761 (mark_memory): Omit 3rd (offset) arg; caller changed.
5762 Don't assume EMACS_INT alignment is the same as pointer alignment.
5764 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
5766 * keyboard.c (read_key_sequence_remapped): New var.
5767 (read_key_sequence): Compute remapping in the right buffer.
5768 (command_loop_1): Use read_key_sequence's remapping directly.
5770 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5772 * dired.c (file_name_completion): Don't expand file name.
5773 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
5774 before checking file name handler.
5776 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
5777 they've been requested explicitly (bug#9591).
5779 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
5781 * keymap.c (Fsingle_key_description): Use make_specified_string
5782 instead of build_string to build string from push_key_description.
5783 (Bug#5193)
5785 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
5787 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
5788 This fixes a Y2038 bug on 64-bit hosts.
5789 * buffer.c (reset_buffer):
5790 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
5791 (Fclear_buffer_auto_save_failure):
5792 Use 0, not -1, to represent an unset failure time, since time_t
5793 might not be signed.
5795 Remove dependency on glibc malloc internals.
5796 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5797 Move back here from lisp.h, but with their new implementations.
5798 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5799 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
5800 * charset.c (charset_table_init): New static var.
5801 (syms_of_charset): Use it instead of xmalloc. This removes a
5802 dependency on glibc malloc internals. See Eli Zaretskii's comment in
5803 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
5804 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5805 Move back to alloc.c.
5806 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5807 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
5809 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
5811 * nsterm.m (windowDidResize): Call x_set_window_size only when
5812 ns_in_resize is true. Otherwise set pixelwidth/height and
5813 call change_frame_size (Bug#9628).
5815 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
5817 Port --enable-checking=all to Fedora 14 x86-64.
5818 * charset.c (syms_of_charset): Also account for glibc malloc's
5819 internal overhead when calculating the initial malloc maximum.
5821 Port --enable-checking=all to Fedora 14 x86.
5822 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5823 Move to lisp.h.
5824 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
5825 (overrun_check_realloc, overrun_check_free):
5826 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
5827 That way, xmalloc returns a properly-aligned pointer even if
5828 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
5829 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
5830 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
5831 into account when calculating the initial malloc maximum.
5832 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5833 Move here from alloc.c, so that charset.c can use it too.
5834 Properly align; the old code wasn't right for common 32-bit hosts
5835 when configured with --enable-checking=all.
5836 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5837 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
5839 2011-09-29 Eli Zaretskii <eliz@gnu.org>
5841 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
5842 use EDOM.
5844 2011-09-28 Eli Zaretskii <eliz@gnu.org>
5846 * xdisp.c (compute_display_string_end): If there's no display
5847 string at CHARPOS, return -1.
5849 * bidi.c (bidi_fetch_char): When compute_display_string_end
5850 returns a negative value, treat the character as a normal
5851 character not covered by a display string. (Bug#9624)
5853 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
5855 * lread.c (Fread_from_string): Fix typo in docstring.
5857 2011-09-27 Eli Zaretskii <eliz@gnu.org>
5859 * xdisp.c (handle_invisible_prop): If invisible text ends on a
5860 newline, reseat the iterator instead of bidi-iterating there one
5861 character at a time. (Bug#9610)
5862 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
5863 TO_CHARPOS if the bidi iterator is at base embedding level.
5865 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
5867 * lread.c (readevalloop): Use correct code for NBSP.
5868 (read1): Likewise. (Bug#9608)
5870 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
5872 * dbusbind.c (Fdbus_register_signal): When service is not
5873 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
5875 2011-09-25 Glenn Morris <rgm@gnu.org>
5877 * buffer.c (truncate-lines): Doc fix.
5879 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
5881 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
5882 (Fset_window_next_buffers): Doc fix.
5884 2011-09-24 Glenn Morris <rgm@gnu.org>
5886 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
5888 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
5890 Fix minor problems found by static checking.
5891 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
5892 * indent.c (Fvertical_motion): Fix == vs = typo.
5894 2011-09-24 Eli Zaretskii <eliz@gnu.org>
5896 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
5897 Default value is now t. Doc fix.
5899 * indent.c (Fvertical_motion): Compute and apply the overshoot
5900 logic when moving up, not only when moving down. Fix the
5901 confusing name and values of the it_overshoot_expected variable;
5902 logic changes accordingly. (Bug#9254) (Bug#9549)
5904 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
5905 CHARPOS is covered by a display string which includes newlines.
5906 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
5907 is covered by a display string with embedded newlines.
5909 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
5911 * dbusbind.c (Fdbus_register_signal): Add match rule to
5912 Vdbus_registered_objects_table. (Bug#9581)
5913 (Fdbus_register_method, Vdbus_registered_objects_table):
5914 Fix docstring.
5916 2011-09-24 Jim Meyering <meyering@redhat.com>
5918 do not ignore write error for any output size
5919 The previous change was incomplete.
5920 While it makes emacs --batch detect the vast majority of stdout
5921 write failures, errors were still ignored whenever the output size is
5922 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
5923 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
5924 && echo FAIL: ignored write error
5925 FAIL: ignored write error
5926 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
5927 && echo FAIL: ignored write error
5928 FAIL: ignored write error
5929 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
5931 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
5933 * emacs.c (Fkill_emacs): In noninteractive mode exit
5934 non-successfully if a write error occurred on stdout. (Bug#9574)
5936 2011-09-21 Eli Zaretskii <eliz@gnu.org>
5938 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
5939 the xassert test.
5941 * dispextern.h (struct it): Update the comment documenting what
5942 can it->OBJECT be.
5944 2011-09-20 Eli Zaretskii <eliz@gnu.org>
5946 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
5947 a display string, extend search for cursor position to end of row.
5948 (find_row_edges): If the row ends in a newline from a display
5949 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
5950 Handle the case of a display string with multiple newlines.
5951 (Fcurrent_bidi_paragraph_direction): Fix search for previous
5952 non-empty line. Fixes confusing cursor motion with arrow keys at
5953 the beginning of a line that starts with whitespace.
5955 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
5957 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
5958 (bug#9493).
5960 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
5962 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
5963 boolean (Bug#9154).
5965 2011-09-18 Eli Zaretskii <eliz@gnu.org>
5967 * xdisp.c (display_line): Record maximum and minimum buffer
5968 positions even if no glyphs were produced (e.g., by a zero-width
5969 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
5970 buffer positions that will be removed from the glyph row because
5971 they don't fit.
5972 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
5973 column is beyond frame width: don't subtract 1 "pixel" when
5974 computing width of the stretch.
5975 (reseat_at_next_visible_line_start): Undo the change made on
5976 2011-09-17 that saved paragraph information and restored it after
5977 the call to `reseat'. (Bug#9545)
5979 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5981 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
5982 and turn window cursor on if cleared (Bug#9415).
5984 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
5986 * search.c (boyer_moore): Take unibyte characters from pattern
5987 literally. (Bug#9458)
5989 2011-09-18 Eli Zaretskii <eliz@gnu.org>
5991 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
5993 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
5995 Fix minor problem found by static checking.
5996 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
5997 initialized, to pacify gcc -Wuninitialized.
5999 * fileio.c: Report proper errno when syscall falls.
6000 (Finsert_file_contents): Save and restore errno,
6001 so that report_file_error outputs the correct diagnostic.
6002 (Fwrite_region) [CLASH_DETECTION]: Likewise.
6004 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6006 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
6008 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6010 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
6011 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
6013 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6015 * xdisp.c (reseat_at_next_visible_line_start): Keep information
6016 about the current paragraph and restore it after the call to reseat.
6018 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
6019 (bidi_find_paragraph_start): Search back for paragraph beginning
6020 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
6021 (bidi_move_to_visually_next): Only trigger paragraph-related
6022 computations when the last character is a newline or at EOB, not
6023 just any NEUTRAL_B. (Bug#9470)
6025 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
6026 truncated lines if point is covered by a display string. (Bug#9524)
6028 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
6030 * xselect.c: Relax test for outgoing X longs (Bug#9498).
6031 (cons_to_x_long): New function.
6032 (lisp_data_to_selection_data): Use it. Correct the test for
6033 short-versus-long data; it was negated. Break out of vector
6034 loop, for efficiency, when a long datum is discovered.
6036 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
6038 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
6040 2011-09-16 Eli Zaretskii <eliz@gnu.org>
6042 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
6043 GCC PR/17406) by declaring this function with external scope.
6045 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6047 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
6048 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
6050 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
6052 * editfns.c (Fformat): Correctly handle text properties on "%%".
6054 2011-09-15 Eli Zaretskii <eliz@gnu.org>
6056 * xterm.c (x_draw_composite_glyph_string_foreground):
6057 * w32term.c (x_draw_composite_glyph_string_foreground):
6058 * term.c (encode_terminal_code):
6059 * composite.c (composition_update_it, get_composition_id):
6060 * xdisp.c (get_next_display_element)
6061 (fill_composite_glyph_string): Add comments about special meaning
6062 of TAB characters in a composition.
6064 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6066 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
6067 This occurs when processing a multibyte format.
6068 Problem reported by Wolfgang Jenker.
6070 2011-09-15 Johan Bockgård <bojohan@gnu.org>
6072 * xdisp.c (try_cursor_movement): Only check for exact match if
6073 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
6075 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6077 Remove unused external symbols.
6078 * dispextern.h (calc_pixel_width_or_height): Remove decl.
6079 * xdisp.c (calc_pixel_width_or_height): Now static.
6080 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
6081 * indent.c (check_display_width):
6082 * w32term.c: Fix comment to match code.
6083 * xterm.c, xterm.h (x_catching_errors): Remove.
6085 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6087 * xselect.c: Use signed conversions more consistently (Bug#9498).
6088 (selection_data_to_lisp_data): Assume incoming selection data are
6089 signed integers, not unsigned. This is to be consistent with
6090 outgoing selection data, which was modified to use signed integers
6091 in as part of the fix to Bug#9196 in response to Jan D.'s comment
6092 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
6093 expects long, not unsigned long.
6095 2011-09-14 Eli Zaretskii <eliz@gnu.org>
6097 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
6098 computation of loop end. Reported by Johan Bockgård
6099 <bojohan@gnu.org>.
6101 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
6103 * frame.c (Fother_visible_frames_p): Function deleted.
6105 2011-09-12 Eli Zaretskii <eliz@gnu.org>
6107 * indent.c (compute_motion): Process display vector front to back
6108 rather than the other way around. (Bug#2496)
6110 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6112 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
6114 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
6116 * minibuf.c (Fread_from_minibuffer): Doc fix.
6118 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6120 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
6121 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
6123 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
6125 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
6126 value for non-existent files.
6128 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6130 * fileio.c (Finsert_file_contents): If the file cannot be opened,
6131 set its "size" to -1. This will set the modtime_size field of
6132 the corresponding buffer to -1, which is what
6133 verify-visited-file-modtime expects for files that do not exist.
6134 (Bug#9139)
6136 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
6138 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
6139 here ...
6140 * lisp.h: ... from here. push_key_description is no longer
6141 defined in keyboard.c, so its declaration should not be in
6142 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
6143 logically belongs with push_key_description.
6145 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
6147 * buffer.h: Include <sys/types.h> instead of <time.h>.
6148 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
6149 Problem reported by Herbert J. Skuhra.
6151 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
6153 * xml.c (parse_region): Make the parsing work for
6154 non-comment-starting XML files again (bug#9144).
6156 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
6158 * image.c (gif_load): Fix calculation of bottom and right corner.
6159 (Bug#9468)
6161 2011-09-10 Eli Zaretskii <eliz@gnu.org>
6163 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
6164 redisplay in small windows.
6166 2011-09-09 Eli Zaretskii <eliz@gnu.org>
6168 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
6170 2011-09-08 Martin Rudalics <rudalics@gmx.at>
6172 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
6173 Operate on live windows only.
6175 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
6177 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
6179 2011-09-07 Eli Zaretskii <eliz@gnu.org>
6181 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
6182 only under bidi iteration.
6184 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
6186 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
6188 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6190 isnan: Fix porting problem to Solaris 10 with bundled gcc.
6191 Without this fix, the command to link temacs failed due to an
6192 undefined symbol __builtin_isnan. This is because
6193 /usr/include/iso/math_c99.h #defines isnan(x) to
6194 __builtin_isnan(x), but the bundled gcc, which identifies itself
6195 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
6196 a __builtin_isnan.
6197 * floatfns.c (isnan): #undef, and then #define to a clone of
6198 what's in data.c.
6199 (Fisnan): Always define, since it's always available now.
6200 (syms_of_floatfns): Always define isnan at the Lisp level.
6202 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6204 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
6206 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6208 * fileio.c: Fix bugs with large file offsets (Bug#9428).
6209 The previous code assumed that file offsets (off_t values) fit in
6210 EMACS_INT variables, which is not true on typical 32-bit hosts.
6211 The code messed up by falsely reporting buffer overflow in cases
6212 such as (insert-file-contents "big" nil 1 2) into an empty buffer
6213 when "big" contains more than 2**29 bytes, even though this
6214 inserts just one byte and does not overflow the buffer.
6215 (Finsert_file_contents): Store file offsets as off_t
6216 values, not as EMACS_INT values. Check for overflow when
6217 converting between EMACS_INT and off_t. When checking for
6218 buffer overflow or for overlap, take the offsets into account.
6219 Don't use EMACS_INT for small values where int suffices.
6220 When checking for overlap, fix a typo: ZV was used where
6221 ZV_BYTE was intended.
6222 (Fwrite_region): Don't assume off_t fits into 'long'.
6223 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
6225 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
6227 * dbusbind.c (xd_signature_cat): Rename from signature_cat.

6231 sprintf-related integer and memory overflow issues (Bug#9412).
6233 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
6234 (esprintf, exprintf, evxprintf): New functions.
6235 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
6236 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
6237 (modify_event_symbol): Do not assume that the length of
6238 name_alist_or_stem is safe to alloca and fits in int.
6239 (Fexecute_extended_command): Likewise for function name and binding.
6240 (Frecursion_depth): Wrap around reliably on integer overflow.
6241 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
6242 since some callers pass EMACS_INT values.
6243 (Fsingle_key_description): Don't crash if symbol name contains more
6244 than MAX_ALLOCA bytes.
6245 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
6246 (get_minibuffer): Arg is now EMACS_INT, not int.
6247 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
6248 (esprintf, exprintf, evxprintf): New decls.
6249 * window.h (command_loop_level, minibuf_level): Reflect API changes.
6251 * dbusbind.c (signature_cat): New function.
6252 (xd_signature, Fdbus_register_signal):
6253 Do not overrun buffer; instead, report string overflow.
6255 * dispnew.c (add_window_display_history): Don't overrun buffer.
6256 Truncate instead; this is OK since it's just a log.
6258 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
6259 even if the time zone offset is outlandishly large.
6260 Don't mishandle offset == INT_MIN.
6262 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
6263 when creating daemon; the previous buffer-overflow check was incorrect.
6265 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
6266 which has the guts of the old verror function.
6268 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
6269 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
6271 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
6272 (font_unparse_xlfd): Don't blindly alloca long strings.
6273 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
6274 fits in int, when using sprintf. Use single snprintf to count
6275 length of string rather than counting it via multiple sprintfs;
6276 that's simpler and more reliable.
6277 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
6278 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
6279 sprintf, in case result does not fit in int.
6281 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
6282 (fontset_from_font): Print it.
6284 * frame.c (tty_frame_count): Now printmax_t, not int.
6285 (make_terminal_frame, set_term_frame_name): Print it.
6286 (x_report_frame_params): In X, window IDs are unsigned long,
6287 not signed long, so print them as unsigned.
6288 (validate_x_resource_name): Check for implausibly long names,
6289 and don't assume name length fits in 'int'.
6290 (x_get_resource_string): Don't blindly alloca invocation name;
6291 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
6292 not fit in int.
6294 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
6295 (xg_check_special_colors, xg_set_geometry):
6296 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
6298 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
6299 Use esprintf, not sprintf, in case result does not fit in int.
6301 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6302 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
6303 it as a large positive number.
6304 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
6305 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6307 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
6308 in case result does not fit in int.
6310 * print.c (float_to_string): Detect width overflow more reliably.
6311 (print_object): Make sprintf buffer a bit bigger, to avoid potential
6312 buffer overrun. Don't assume list length fits in 'int'. Treat
6313 print length of 0 as 0, not as infinity; to be consistent with other
6314 uses of print length in this function. Don't overflow print length
6315 index. Don't assume hash table size fits in 'long', or that
6316 vectorlike size fits in 'unsigned long'.
6318 * process.c (make_process): Use printmax_t, not int, to format
6319 process-name gensyms.
6321 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
6323 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
6324 to avoid potential buffer overrun.
6326 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
6327 if X resource line is longer than 512 bytes.
6329 * xfns.c (x_window): Make sprintf buffer a bit bigger
6330 to avoid potential buffer overrun.
6332 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
6334 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
6336 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6338 Integer overflow fixes for scrolling, etc.
6339 Without these, Emacs silently mishandles large integers sometimes.
6340 For example, "C-u 4294967297 M-x recenter" was treated as if
6341 it were "C-u 1 M-x recenter" on a typical 64-bit host.
6343 * xdisp.c (try_window_id): Check Emacs fixnum range before
6344 converting to 'int'.
6346 * window.c (window_scroll_line_based, Frecenter):
6347 Check that an Emacs fixnum is in range before assigning it to 'int'.
6348 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
6349 values converted from Emacs fixnums.
6350 (Frecenter): Don't wrap around a line count if it is out of 'int'
6351 range; instead, treat it as an extreme value.
6352 (Fset_window_configuration, compare_window_configurations):
6353 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
6355 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
6356 that can exceed INT_MAX. Check that EMACS_INT value is in range
6357 before assigning it to the (possibly-narrower) index.
6358 (match_limit): Don't assume that a fixnum can fit in 'int'.
6360 * print.c (print_object): Use ptrdiff_t, not int, for index that can
6361 exceed INT_MAX.
6363 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
6364 (Fvertical_motion): Don't wrap around LINES values that don't fit
6365 in 'int'. Instead, treat them as extreme values. This is good
6366 enough for windows, which can't have more than INT_MAX lines anyway.
6368 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
6370 * Require libxml/parser.h to avoid compilation warning.
6372 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
6374 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
6375 since this reportedly can destroy thread storage.
6377 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
6379 * syntax.c (find_defun_start): Update all cache variables if
6380 exiting early (Bug#9401).
6382 2011-08-30 Eli Zaretskii <eliz@gnu.org>
6384 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
6386 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
6387 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
6388 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
6390 * term.c (tty_append_glyph): New function.
6391 (produce_stretch_glyph): Static function and its prototype deleted.
6393 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
6394 Add prototypes.
6396 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
6398 * image.c (parse_image_spec): Check for nonnegative, not for positive,
6399 when checking :margin (Bug#9390).
6400 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
6401 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
6402 so that the name doesn't mislead. All uses changed.
6404 2011-08-28 Johan Bockgård <bojohan@gnu.org>
6406 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
6407 set_tty_hooks.
6409 2011-08-27 Eli Zaretskii <eliz@gnu.org>
6411 * xdisp.c (move_it_to): Don't bail out early when reaching
6412 position beyond to_charpos, if we are scanning backwards.
6413 (move_it_vertically_backward): When DY == 0, make sure we get to
6414 the first character in the line after the newline.
6416 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
6418 * ccl.c: Improve and simplify overflow checking (Bug#9196).
6419 (ccl_driver): Do not generate an out-of-range pointer.
6420 (Fccl_execute_on_string): Remove unnecessary check for
6421 integer overflow, noted by Stefan Monnier in
6422 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
6423 Remove a FIXME that didn't need fixing.
6424 Simplify the newly-introduced buffer reallocation code.
6426 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
6428 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
6430 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
6432 Integer and memory overflow issues (Bug#9196).
6434 * doc.c (get_doc_string): Rework so that
6435 get_doc_string_buffer_size is the actual buffer size, rather than
6436 being 1 less than the actual buffer size; this makes xpalloc more
6437 convenient.
6439 * image.c (x_allocate_bitmap_record, cache_image):
6440 * xselect.c (Fx_register_dnd_atom):
6441 Simplify previous changes by using xpalloc.
6443 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
6444 since either will do and ptrdiff_t is convenient with xpalloc.
6446 * charset.c (charset_table_size)
6447 (struct charset_sort_data.priority): Now ptrdiff_t.
6448 (charset_compare): Don't overflow if priorities differ greatly.
6449 (Fsort_charsets): Don't assume list length fits in int.
6450 Check for size-calculation overflow when allocating sort data.
6451 (syms_of_charset): Allocate an initial charset table that is
6452 just under 64 KiB, to avoid problems with glibc malloc and mmap.
6454 * cmds.c (internal_self_insert): Check for size-calculation overflow.
6456 * composite.h (struct composition.glyph_len): Now int, not unsigned.
6457 The actual value is always <= INT_MAX, and leaving it unsigned made
6458 overflow checking harder.
6460 * dispextern.h (struct glyph_matrix.rows_allocated)
6461 (struct face_cache.size): Now ptrdiff_t, for convenience in use
6462 with xpalloc. The values are still always <= INT_MAX.
6464 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
6466 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
6467 (SAFE_NALLOCA): New macro.
6469 * region-cache.c (struct boundary.pos, find_cache_boundary)
6470 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
6471 (set_cache_region, invalidate_region_cache)
6472 (revalidate_region_cache, know_region_cache, region_cache_forward)
6473 (region_cache_backward, pp_cache):
6474 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
6475 so that ptrdiff_t * can be passed to xpalloc.
6476 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
6477 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
6478 (pp_cache): Don't assume cache_len fits in int.
6479 * region-cache.h: Adjust extern decls to match.
6481 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
6482 EMACS_INT, since either will do, for xpalloc.
6484 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
6485 (xnmalloc, xnrealloc, xpalloc): New functions.
6487 * bidi.c (bidi_shelve_header_size): New constant.
6488 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
6489 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
6491 * bidi.c (bidi_cache_shrink):
6492 * buffer.c (overlays_at, overlays_in, record_overlay_string)
6493 (overlay_strings):
6494 Don't update size of array until after memory allocation succeeds,
6495 because xmalloc/xrealloc may not return.
6496 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
6497 now that we have proper integer overflow checking.
6498 (record_overlay_string, overlay_strings): Catch overflows when
6499 calculating size of overlay_str_buf.
6501 * callproc.c (Fcall_process): Check for size overflow when
6502 calculating size of args2.
6503 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
6504 Normally we prefer signed values, but sticking with ptrdiff_t would
6505 require adding more-complicated checks.
6507 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
6508 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
6509 Redo buffer-overflow calculations to avoid integer overflow.
6510 Add a FIXME comment where memory seems to be over-allocated.
6512 * character.c (Fstring): Check for size-calculation overflow.
6514 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
6515 unnecessary integer overflow. Check for size overflow.
6516 (encode_coding_object): Don't update size until xmalloc succeeds.
6518 * composite.c (get_composition_id): Check for overflow in glyph
6519 length calculations.
6521 Integer and memory overflow fixes for display code.
6522 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
6523 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
6524 (scrolling_window): Check for overflow in size calculations.
6525 (line_draw_cost, realloc_glyph_pool, add_row_entry):
6526 Don't assume glyph table len fits in int.
6527 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
6528 (row_table_size): Now ptrdiff_t, not int.
6529 (scrolling_window): Avoid overflow in size calculations.
6530 Don't update size until allocation succeeds.
6531 * fns.c (concat): Check for overflow in size calculations.
6532 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
6533 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
6534 (NEXT_ALMOST_PRIME_LIMIT): New constant.
6536 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
6537 (get_doc_string): Check for size calculation overflow.
6538 Don't update size until allocation succeeds.
6539 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
6540 EMACS_INT, where ptrdiff_t will do.
6541 (Fsubstitute_command_keys): Check for string overflow.

6544 fits in int.
6545 (message_length): Now ptrdiff_t, not int.
6546 (Fmessage_box): Don't update size until allocation succeeds.
6547 Don't assume message length fits in int.
6548 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
6550 * emacs.c (main): Do not reallocate argv, since there is a null at
6551 the end that can be overwritten, and this way there's no need to
6552 worry about size-calculation overflow.
6553 (sort_args): Check for size-calculation overflow.
6555 * eval.c (init_eval_once, grow_specpdl): Don't update size until
6556 alloc succeeds.
6557 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
6559 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
6560 (x_set_scroll_bar_width, x_figure_window_size):
6561 Check for integer overflow.
6562 (x_set_alpha): Do not assume XINT fits in int.
6564 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
6565 This is for the members text_lines, text_cols, total_lines, total_cols,
6566 where the system imposes an 'int' limit.
6568 * fringe.c (Fdefine_fringe_bitmap):
6569 Don't update size until alloc works.
6571 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
6572 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
6574 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
6575 Check for size-calculation overflow.
6576 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
6577 do, as we prefer signed integers.
6578 (id_to_widget.max_size, id_to_widget.used)
6579 (xg_store_widget_in_map, xg_remove_widget_from_map)
6580 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
6581 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
6582 Use and return ptrdiff_t, not int.
6583 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
6584 * gtkutil.h: Change prototypes to match the above.
6586 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
6587 are duplicate now that they've been promoted to lisp.h.
6588 (x_allocate_bitmap_record, x_alloc_image_color)
6589 (make_image_cache, cache_image, xpm_load):
6590 Don't update size until alloc is done.
6591 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
6592 (x_detect_edges):
6593 Check for size calculation overflow.
6594 (ct_colors_allocated_max): New constant.

6599 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
6600 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
6601 Use ptrdiff_t, not int, to count maps.
6602 (read_char_minibuf_menu_prompt): Check for overflow in size
6603 calculations. Don't update size until allocation succeeds.
6604 Redo calculations to avoid overflow.
6605 * keyboard.h: Change prototypes to match the above.

6610 * keymap.h: Change prototypes to match the above.
6612 * lread.c (read1, init_obarray): Don't update size until alloc done.
6614 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
6615 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
6617 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):

6630 * search.c (Freplace_match): Check for size calculation overflow.
6631 (Fset_match_data): Don't assume list lengths fit in 'int'.
6633 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
6634 for command line length. Do not attempt to address one before the
6635 beginning of an array, as that's not portable.
6637 * term.c (max_frame_lines): Remove; unused.
6638 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
6639 not int.

6647 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
6648 subtracting pointers.

6650 until alloc done.
6652 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
6653 Don't update size until alloc done.
6654 Redo size calculations to avoid overflow.

6662 * xfaces.c (lface_id_to_name_size, Finternal_make_lisp_face):
6663 Use ptrdiff_t, not int, for sizes.
6664 (Finternal_make_lisp_face, cache_face):
6665 Check for size calculation overflow.
6666 (cache_face): Treat size calculation overflows as if they were
6667 memory exhaustion (the usual treatment), rather than aborting.
6669 * xfns.c (x_encode_text, x_set_name_internal)
6670 (Fx_change_window_property): Use ptrdiff_t, not int, to count
6671 sizes, since they can exceed INT_MAX in size. Check for size

6675 (xg_select): Check for size calculation overflow.
6676 Don't update size until alloc done.
6678 * xrdb.c (get_environ_db): Don't assume path length fits in int,
6679 as sprintf is limited to int lengths.
6681 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
6682 (X_LONG_MIN): New macros.
6683 Use them to make the following changes clearer.
6684 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
6685 This change doesn't affect the value now, but it may help remind
6686 future maintainers not to raise the value too much later.
6687 (SELECTION_QUANTUM): Remove, replacing with ...
6688 (selection_quantum): ... new function, which avoids overflow.
6689 All uses changed.
6690 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
6691 assumption that selection length fits in 'int'.
6692 (x_reply_selection_request, x_handle_selection_request)
6693 (x_get_window_property, receive_incremental_selection)
6694 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
6695 (lisp_data_to_selection_data, clean_local_selection_data):
6696 Use ptrdiff_t, not int, to record length of selection.
6697 (x_reply_selection_request, x_get_window_property)
6698 (receive_incremental_selection, x_property_data_to_lisp):
6699 Redo calculations to avoid overflow.
6700 (x_reply_selection_request): When sending hint, ceiling it at
6701 X_LONG_MAX rather than relying on wraparound overflow to send
6702 something.
6703 (x_get_window_property, receive_incremental_selection)
6704 (lisp_data_to_selection_data, x_property_data_to_lisp):
6705 Check for size-calculation overflow.
6706 (x_get_window_property, receive_incremental_selection)
6707 (lisp_data_to_selection_data, Fx_register_dnd_atom):
6708 Don't store size until memory allocation succeeds.
6709 (x_get_window_property): Plug memory leak on memory exhaustion.
6710 Don't double-block input; malloc is safe here. Don't assume 2**34
6711 - 4 fits in unsigned long. Add an xassert to check
6712 XGetWindowProperty overflow. Be more careful about overflow
6713 calculations, and distinguish size from memory overflow better.
6714 (receive_incremental_selection): When tracing, don't assume
6715 unsigned int is less than INT_MAX.
6716 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
6717 harmful) conversions of unsigned short to int.
6718 (lisp_data_to_selection_data): Don't assume that integers
6719 in the range -65535 through -1 fit in an X unsigned short.
6720 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
6721 result parameters unless successful. Rely on cons_to_unsigned
6722 to report problems with elements; the old code wasn't right anyway.
6723 (x_check_property_data): Check for int overflow; we cannot use
6724 a wider type due to X limits.
6725 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
6727 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
6729 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
6730 (x_term_init): Check for size calculation overflow.
6731 (x_color_cells): Don't store size until memory allocation succeeds.
6732 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
6733 Don't assume alloca size is less than MAX_ALLOCA.
6734 (x_term_init): Don't assume length fits in int (sprintf is limited
6735 to int size).
6737 Use ptrdiff_t for composition IDs.
6738 * character.c (lisp_string_width):
6739 * composite.c (composition_table_size, n_compositions)
6740 (get_composition_id, composition_gstring_from_id):

6755 * fns.c (hash_lookup, hash_put, Fgethash, Fputhash):
6756 * image.c (xpm_get_color_table_h):
6757 * lisp.h (hash_lookup, hash_put):
6758 * minibuf.c (Ftest_completion):
6759 Use ptrdiff_t for hash table indexes, not int (which is too
6760 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
6761 32-bit --with-wide-int hosts).
6763 * charset.c (Fdefine_charset_internal): Check for integer overflow.
6764 Add a FIXME comment about memory leaks.
6765 (syms_of_charset): Don't assume xmalloc returns.
6767 Don't assume that stated character widths fit in int.
6768 * character.c (Fchar_width, c_string_width, lisp_string_width):
6769 * character.h (CHAR_WIDTH):
6770 * indent.c (MULTIBYTE_BYTES_WIDTH):
6771 Use sanitize_char_width to avoid undefined and/or bad behavior
6772 with outlandish widths.
6773 * character.h (sanitize_tab_width): Rename from sanitize_width,
6774 now that we have two such functions. All uses changed.
6775 (sanitize_char_width): New inline function.
6777 Don't assume that tab-width fits in int.
6778 * character.h (sanitize_width): New inline function.
6779 (SANE_TAB_WIDTH): New macro.
6780 (ASCII_CHAR_WIDTH): Use it.
6781 * indent.c (sane_tab_width): Remove. All uses replaced by
6782 SANE_TAB_WIDTH (current_buffer).
6783 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
6785 * fileio.c: Integer overflow issues with file modes.
6786 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
6788 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
6789 Remove unreachable code.
6790 (read_hex, load_charset_map_from_file): Check for integer overflow.
6792 * xterm.c: Don't go over XClientMessageEvent limit.
6793 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
6794 (x_send_scroll_bar_event): Likewise. Check that the size does not
6795 exceed limits imposed by XClientMessageEvent, as well as the usual
6796 ptrdiff_t and size_t limits.
6798 * keyboard.c: Overflow, signedness and related fixes.
6799 (make_lispy_movement): Use same integer type in forward decl
6800 that is used in the definition.
6801 (read_key_sequence, keyremap_step):
6802 Change bufsize argument back to int, undoing my 2011-03-30 change.
6803 We prefer signed types, and int is wide enough here.
6804 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
6805 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
6806 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
6807 length, not size_t. Use ptrdiff_t for index, not int.
6808 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
6809 possibility of integer overflow.
6811 Overflow, signedness and related fixes for images.
6813 * dispextern.h (struct it.stack[0].u.image.image_id)
6814 (struct_it.image_id, struct image.id, struct image_cache.size)
6815 (struct image_cache.used, struct image_cache.ref_count):

6820 * nsmenu.m (update_frame_tool_bar):
6821 * xdisp.c (calc_pixel_width_or_height):
6822 * xfns.c (image_cache_refcount):
6823 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
6824 on typical 64-bit hosts.
6826 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
6827 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

6832 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
6833 (lookup_image): Remove unnecessary tests.
6834 (xbm_image_p): Locals are now of int, not EMACS_INT,
6835 since parse_image_check makes sure they fit into int.
6836 (png_load, gif_load, svg_load_image):
6837 Prefer int to unsigned where either will do.
6838 (tiff_handler): New function, combining the cores of the
6839 old tiff_error_handler and tiff_warning_handler.
6840 This function is rewritten to use vsnprintf and thereby avoid
6841 stack buffer overflows. It uses only the features of vsnprintf
6842 that are common to both POSIX and native Microsoft.
6843 (tiff_error_handler, tiff_warning_handler): Use it.
6844 (tiff_load, gif_load, imagemagick_load_image):
6845 Don't assume :index value fits in 'int'.
6846 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
6847 (imagemagick_load_image): Check that crop parameters fit into
6848 the integer types that MagickCropImage accepts. Don't assume
6849 Vimagemagick_render_type has a nonnegative value. Don't assume
6850 size_t fits in 'long'.
6851 (gs_load): Use printmax_t to print the widest integers possible.
6852 Check for integer overflow when computing image height and width.
6854 2011-08-26 Eli Zaretskii <eliz@gnu.org>
6856 * xdisp.c (redisplay_window): Don't force window start if point
6857 will be invisible in the resulting window. (Bug#9324)
6859 2011-08-25 Eli Zaretskii <eliz@gnu.org>
6861 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
6862 the display spec is of the form `(space ...)'.
6863 (handle_display_spec): Return the value returned by
6864 handle_single_display_spec, not just 1 or zero.
6865 (handle_single_display_spec): If the display spec is of the form
6866 `(space ...)', and specifies display in the text area, return 2
6867 rather than 1.
6868 (try_cursor_movement): Check for the need to scroll more
6869 accurately, and prefer exact match for point under bidi.
6870 Don't advance `row' beyond the last row of the window.
6872 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
6873 into disp_prop; all users changed.
6875 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
6876 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
6877 for the text covered by the display property.
6879 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
6881 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

6887 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
6888 buffers, return left-to-right.
6889 (set_cursor_from_row): Consider candidate row a win if its glyph
6890 represents a newline and point is on that newline. Fixes cursor
6891 positioning on the newline at EOL of R2L text within L2R
6892 paragraph, and vice versa.
6893 (try_cursor_movement): Check continued rows, in addition to
6894 continuation rows. Fixes unwarranted scroll when point enters a
6895 continued line of R2L text within an L2R paragraph, or vice versa.
6896 (cursor_row_p): Consider the case of point being equal to
6897 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
6898 from the end of a short line to the beginning of a continued line
6899 of R2L text within L2R paragraph.
6900 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

6910 a character.
6912 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
6914 * nsfont.m (ns_otf_to_script): Fix typo.
6916 2011-08-22 Kenichi Handa <handa@m17n.org>
6918 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
6919 extra slot even if the purpose is char-code-property-table.
6921 2011-08-23 Eli Zaretskii <eliz@gnu.org>
6923 * xdisp.c (redisplay_window): When computing centering_position,
6924 account for the height of the header line. (Bug#8874)
6926 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
6927 instead of CHAR_TO_BYTE. Fixes a crash when a completion
6928 candidate is selected by the mouse, and that candidate has a
6929 composed character under the mouse.
6931 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
6932 coordinates reported by pos-visible-in-window-p for a composed
6933 character in column zero.
6935 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
6937 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
6939 2011-08-22 Eli Zaretskii <eliz@gnu.org>
6941 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
6942 consider it a hit if to_charpos is anywhere in the range of the
6943 composed buffer positions.
6945 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
6947 * image.c (gif_load): Don't assume that each subimage has the same
6948 dimensions as the base image. Handle disposal method that is
6949 "undefined" by the gif spec (Bug#9335).
6951 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
6953 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
6954 (Fcondition_case): Document `debug' symbol in error handler.
6956 2011-08-19 Eli Zaretskii <eliz@gnu.org>
6958 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
6959 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
6960 from an Org mode buffer to a Speedbar frame.
6962 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
6963 a composition, take its buffer position from IT->cmp_it.charpos.
6964 Fixes cursor positioning at the beginning of a line that begins
6965 with a composed character.
6967 2011-08-18 Eli Zaretskii <eliz@gnu.org>
6969 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
6970 character bidirectional type, use STRONG_L instead. Fixes crashes
6971 in a buffer produced by `describe-categories'.
6973 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
6974 members before the level stack, so they would be saved and
6975 restored when copying iterator state. Fixes incorrect reordering
6976 around TABs covered by display properties.
6978 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
6980 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
6982 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
6984 * eval.c (internal_condition_case, internal_condition_case_1)
6985 (internal_condition_case_2, internal_condition_case_n):
6986 Remove unnecessary aborts (Bug#9081).
6988 2011-08-17 Eli Zaretskii <eliz@gnu.org>
6990 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
6991 has no `load' handler, try opening the file locally. (Bug#9311)
6993 2011-08-16 Ken Brown <kbrown@cornell.edu>
6995 * gmalloc.c: Expand comment.
6997 2011-08-16 Eli Zaretskii <eliz@gnu.org>
6999 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
7000 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
7002 2011-08-16 Ken Brown <kbrown@cornell.edu>
7004 Fix memory allocation problems in Cygwin build (Bug#9273).
7006 * unexcw.c ( __malloc_initialized): Declare external variable.

7011 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
7012 dumped emacs.
7013 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
7014 in the static heap.
7015 [CYGWIN] (special_realloc): New function.
7016 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
7017 requests to realloc storage in the static heap.

7030 * dispextern.h: Fix a typo in the comment to bidi_type_t.
7032 * chartab.c: Improve commentary for the uniprop_table API.
7034 * bidi.c (bidi_paragraph_init): Support zero value of
7035 bidi_ignore_explicit_marks_for_paragraph_level.

7037 biditype.h and bidimirror.h.
7039 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
7040 coordinates of the iterator when restoring from ppos_it.
7041 (Bug#9296)
7043 2011-08-14 Kenichi Handa <handa@m17n.org>
7045 * process.c (create_process): Call setup_process_coding_systems
7046 after the pid of the process is set to -1 (Bug#8162).
7048 2011-08-14 Eli Zaretskii <eliz@gnu.org>
7050 * xdisp.c (move_it_in_display_line_to): Don't invoke
7051 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
7052 ppos_it. Fixes vertical cursor motion when line beginning is
7053 covered by an image. (Bug#9296)
7055 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
7057 * nsterm.h (ns_run_ascript): Declare.
7058 (NSAPP_DATA2_RUNASSCRIPT): Define.
7060 * nsfns.m (as_script, as_result, as_status): New static variables.
7061 (ns_run_ascript): New function.
7062 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
7063 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
7064 the event loop. Get status from as_status (Bug#7276).
7066 * nsterm.m (sendEvent): If event is NSApplicationDefined and
7067 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
7068 the event loop (Bug#7276).
7070 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
7072 * gnutls.c (QCgnutls_bootprop_priority)
7073 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
7074 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
7075 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
7076 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
7077 (QCgnutls_bootprop_verify_hostname_error)
7078 (QCgnutls_bootprop_callbacks_verify): Rename from
7079 Qgnutls_bootprop_..., all uses changed.
7081 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
7082 uses changed.
7084 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
7086 * xfaces.c (Qframe_set_background_mode): Now static.
7087 * dispextern.h (Qframe_set_background_mode): Remove decl.

7091 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
7093 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
7094 (Fnetwork_interface_list): Allocate in increments of bytes instead
7095 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
7096 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
7097 sockaddr.
7098 (struct ifflag_def): notrailers is smart on OSX.
7099 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
7100 Get hardware address with getifaddrs if available.
7102 2011-08-12 Eli Zaretskii <eliz@gnu.org>
7104 * xdisp.c (iterate_out_of_display_property): xassert that
7105 IT->position is set to within IT->object's boundaries. Break from
7106 the loop as soon as EOB is reached; avoids infloops in redisplay
7107 when IT->position is set up wrongly due to some bug.
7108 Set IT->current to match the bidi iterator unconditionally.
7109 (push_display_prop): Allow GET_FROM_STRING as IT->method on
7110 entry. Force push_it to save on the stack the current
7111 buffer/string position, to be restored by pop_it. Fix flags in
7112 the iterator structure wrt the object coming from a display
7113 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
7114 properties. (Bug#9284)
7116 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
7118 * fontset.c (fontset_get_font_group): Add proper type checks.

7128 2011-08-08 Eli Zaretskii <eliz@gnu.org>
7130 * xdisp.c (forward_to_next_line_start): Allow to use the
7131 no-display-properties-and-no-overlays under bidi display.
7132 Set disp_pos in the bidi iterator to avoid searches for display
7133 properties and overlays.
7135 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
7137 * editfns.c (Fset_time_zone_rule): Document relationship with the
7138 setenv function.

7141 the font entity extracted from the cache (Bug#8109).
7143 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
7145 * composite.c (autocmp_chars): Don't reset point. That is done by
7146 restore_point_unwind (Bug#5984).
7148 2011-08-07 Juri Linkov <juri@jurta.org>
7150 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
7151 to show the arg `TIME' instead of `TIMEVAL'.
7153 2011-08-06 Eli Zaretskii <eliz@gnu.org>
7155 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
7156 display property strides EOL and includes a newline, as in
7157 longlines-mode. (Bug#9254)
7158 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
7159 word-wrap under bidirectional display. (Bug#9224)
7161 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
7162 is non-zero, even if the data buffer is NULL. Fixes a crash in
7163 vertical-motion with longlines-mode. (Bug#9254)
7165 2011-08-05 Eli Zaretskii <eliz@gnu.org>
7167 * bidi.c <bidi_cache_total_alloc>: Now static.
7168 (bidi_initialize): Initialize bidi_cache_total_alloc.
7170 * xdisp.c (display_line): Release buffer allocated for shelved bidi
7171 cache. (Bug#9221)
7173 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
7174 amount allocated this far in `bidi_cache_total_alloc'.
7175 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
7176 non-zero, only free the data buffer without restoring the cache
7177 contents. All callers changed.
7179 * dispextern.h (bidi_unshelve_cache): Update prototype.
7181 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
7182 (move_it_in_display_line, move_it_to)
7183 (move_it_vertically_backward, move_it_by_lines): Replace the call
7184 to xfree to an equivalent call to bidi_unshelve_cache.
7185 (move_it_in_display_line_to): Fix logic of returning
7186 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
7188 2011-08-05 Eli Zaretskii <eliz@gnu.org>
7190 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
7191 came from a string character with a `cursor' property. (Bug#9229)
7193 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
7195 * Makefile.in (LIB_PTHREAD): New variable.
7196 (LIBES): Add LIB_PTHREAD (Bug#9216).
7198 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
7199 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
7201 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
7203 * regex.c (re_iswctype): Remove some redundant boolean conversions.
7205 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
7207 * xterm.c (x_find_topmost_parent): New function.
7208 (x_set_frame_alpha): Find topmost parent window with
7209 x_find_topmost_parent and set the property there also (bug#9181).
7210 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
7212 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
7214 * callproc.c (Fcall_process): Avoid vfork clobbering
7215 the local vars buffer, coding_systems, current_dir.
7217 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
7219 * keymap.c (Fmake_composed_keymap): Move to subr.el.
7221 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
7223 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
7224 so that it is not optimized away.
7226 * xdisp.c (compute_display_string_pos): Remove unused local.
7228 2011-08-02 Eli Zaretskii <eliz@gnu.org>
7230 Fix slow cursor motion and scrolling in large buffers with
7231 selective display, like Org Mode buffers. (Bug#9218)
7233 * dispextern.h (struct bidi_it): New member disp_prop_p.
7235 * xdisp.c: Remove one-slot cache of display string positions.
7236 (compute_display_string_pos): Accept an additional argument
7237 DISP_PROP_P; callers changed. Scan at most 5K characters forward
7238 for a display string or property. If found, set DISP_PROP_P
7239 non-zero.
7241 * bidi.c (bidi_fetch_char): Accept an additional argument
7242 DISP_PROP_P, and pass it to compute_display_string_pos.
7243 Only handle text covered by a display string if DISP_PROP_P is returned
7244 non-zero. All callers of bidi_fetch_char changed.
7246 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
7248 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
7250 2010-12-03 Don March <don@ohspite.net>
7252 * keymap.c (Fdefine_key): Fix non-prefix key error message when
7253 last character M-[char] is translated to ESC [char] (bug#7541).
7255 2011-08-02 Kenichi Handa <handa@m17n.org>
7257 * lisp.h (uniprop_table): Extern it.
7259 * chartab.c (uniprop_table): Make it non-static.
7261 2011-08-01 Eli Zaretskii <eliz@gnu.org>
7263 * xdisp.c (forward_to_next_line_start): Accept additional argument
7264 BIDI_IT_PREV, and store into it the state of the bidi iterator had
7265 on the newline.
7266 (reseat_at_next_visible_line_start): Use the bidi iterator state
7267 returned by forward_to_next_line_start to restore the state of
7268 it->bidi_it after backing up to previous newline. (Bug#9212)
7270 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
7272 * regex.c (re_comp): Protoize.
7273 (re_exec): Fix return type.
7274 (regexec): Fix type of `ret'. (Bug#9203)
7276 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7278 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
7279 This is needed if max-image-size is a floating-point number.
7281 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
7283 * print.c (print_object): Print empty symbol as ##.
7285 * lread.c (read1): Read ## as empty symbol.
7287 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
7289 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
7290 setting frame foreground color (Bug#9175).
7291 (x_set_background_color): Likewise.
7293 * nsmenu.m (-setText): Size tooltip dimensions precisely to
7294 contents (Bug#9176).
7295 (EmacsTooltip -init): Remove bezels and add shadows to
7296 tooltip windows.
7298 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
7299 or scroll bar (Bug#8470).
7301 * nsfont.m (nsfont_open): Remove assignment to voffset and
7302 unnecessary vars hshink, expand, hd, full_height, min_height.
7303 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
7305 * nsterm.h (nsfont_info): Remove voffset field.
7307 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
7309 Implement strike-through and overline on NextStep (Bug#8863).
7311 * nsfont.m (nsfont_open): Use underline position provided by font,
7312 instead of hard-coded value of 2.
7313 (nsfont_draw): Call ns_draw_text_decoration instead.
7315 * nsterm.h: Add declaration for ns_draw_text_decoration.
7317 * nsterm.m (ns_draw_text_decoration): New function for drawing
7318 underline, overline, and strike-through.
7319 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
7320 ns_draw_text_decoration. Change treatment of cursor drawing to
7321 accommodate underlining, etc.
7323 2011-07-28 Eli Zaretskii <eliz@gnu.org>
7325 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
7326 default.
7328 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7330 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
7331 Without this fix, if a signal arrives just after memory fills up,
7332 'malloc' might be invoked reentrantly.
7334 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
7335 In other words, assume that every image size is allowed, on non-X
7336 hosts. This assumption is probably wrong, but it lets Emacs compile.
7338 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
7340 * regex.c (re_iswctype): Convert return values to boolean.
7342 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
7344 * xdisp.c (compute_display_string_pos): Don't use cached display
7345 string position if the buffer had its restriction changed.
7346 (Bug#9184)
7348 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7350 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
7352 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7354 Integer signedness and overflow and related fixes. (Bug#9079)
7356 * bidi.c: Integer size and overflow fixes.
7357 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
7358 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
7359 (bidi_cache_find_level_change, bidi_cache_ensure_space)
7360 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
7361 (bidi_find_other_level_edge):
7362 Use ptrdiff_t instead of EMACS_INT where either will do.
7363 This works better on 32-bit hosts configured --with-wide-int.
7364 (bidi_cache_ensure_space): Check for size-calculation overflow.
7365 Use % rather than repeated addition, for better worst-case speed.
7366 Don't set bidi_cache_size until after xrealloc returns, because it
7367 might not return.
7368 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
7369 (bidi_cache_ensure_space): Also check that the bidi cache size
7370 does not exceed that of the largest Lisp string or buffer. See Eli
7371 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
7373 * alloc.c (__malloc_size_t): Remove.
7374 All uses replaced by size_t. See Andreas Schwab's note
7375 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
7377 * image.c: Improve checking for integer overflow.
7378 (check_image_size): Assume that f is nonnull, since
7379 it is always nonnull in practice. This is one less thing to
7380 worry about when checking for integer overflow later.
7381 (x_check_image_size): New function, which checks for integer
7382 overflow issues inside X.
7383 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
7384 This removes the need for a memory_full check.
7385 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
7386 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
7387 (xbm_read_bitmap_data): Change locals back to 'int', since
7388 their values must fit in 'int'.
7389 (xpm_load_image, png_load, tiff_load):
7390 Invoke x_create_x_image_and_pixmap earlier,
7391 to avoid much needless work if the image is too large.
7392 (tiff_load): Treat overly large images as if
7393 x_create_x_image_and_pixmap failed, not as malloc failures.
7394 (gs_load): Use x_check_image_size.
7396 * gtkutil.c: Omit integer casts.
7397 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
7398 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
7400 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
7402 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
7403 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
7404 would wrongly return t on a 64-bit host.
7406 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
7407 The plain *_OVERFLOW macros run afoul of GCC bug 49705
7408 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
7409 and therefore cause GCC to emit a bogus diagnostic in some cases.
7411 * image.c: Integer signedness and overflow and related fixes.
7412 This is not an exhaustive set of fixes, but it's time to
7413 record what I've got.
7414 (lookup_pixel_color, check_image_size): Remove redundant decls.
7415 (check_image_size): Don't assume that arbitrary EMACS_INT values
7416 fit in 'int', or that arbitrary 'double' values fit in 'int'.
7417 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
7418 (tiff_load, imagemagick_load_image):
7419 Check for overflow in size calculations.
7420 (x_create_x_image_and_pixmap): Remove unnecessary test for
7421 xmalloc returning NULL; that can't happen.
7422 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
7423 (xpm_color_bucket): Use better integer hashing function.
7424 (xpm_cache_color): Don't possibly over-allocate memory.
7425 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
7426 (gif_memory_source):
7427 Use ptrdiff_t, not int or size_t, to record sizes.
7428 (png_load): Don't assume values greater than 2**31 fit in 'int'.
7429 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
7430 either works, as we prefer signed integers.
7431 (tiff_read_from_memory, tiff_write_from_memory):
7432 Return tsize_t, not size_t, since that's what the TIFF API wants.
7433 (tiff_read_from_memory): Don't fail simply because the read would
7434 go past EOF; instead, return a short read.
7435 (tiff_load): Omit no-longer-needed casts.
7436 (Fimagemagick_types): Don't assume size fits into 'int'.
7438 Improve hashing quality when configured --with-wide-int.
7439 * fns.c (hash_string): New function, taken from sxhash_string.
7440 Do not discard information about ASCII character case; this
7441 discarding is no longer needed.
7442 (sxhash-string): Use it. Change sig to match it. Caller changed.
7443 * lisp.h: Declare it.
7444 * lread.c (hash_string): Remove, since we now use fns.c's version.
7445 The fns.c version returns a wider integer if --with-wide-int is
7446 specified, so this should help the quality of the hashing a bit.
7448 * emacs.c: Integer overflow minor fix.
7449 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
7450 Define only if GNU_LINUX.
7451 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
7453 * dispnew.c: Integer signedness and overflow fixes.
7454 Remove unnecessary forward decls, that were a maintenance hassle.
7455 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
7456 All uses changed.
7457 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
7458 (scrolling_window): Use ptrdiff_t, not int, for byte count.
7459 (prepare_desired_row, line_draw_cost):
7460 Use int, not unsigned, where either works.
7461 (save_current_matrix, restore_current_matrix):
7462 Use ptrdiff_t, not size_t, where either works.
7463 (init_display): Check for overflow more accurately, and without
7464 relying on undefined behavior.
7466 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
7467 Remove, replacing with the new symbols in lisp.h. All uses changed.
7468 * fileio.c (make_temp_name):
7469 * filelock.c (lock_file_1, lock_file):
7470 * xdisp.c (message_dolog):
7471 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
7472 Use pMd etc. instead.
7473 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
7474 replacing the pWIDE etc. symbols removed from editfns.c.
7476 * keyboard.h (num_input_events): Now uintmax_t.
7477 This is (very slightly) less likely to mess up due to wraparound.
7478 All uses changed.
7480 * buffer.c: Integer signedness fixes.
7481 (alloc_buffer_text, enlarge_buffer_text):
7482 Use ptrdiff_t rather than size_t when either will do, as we prefer
7483 signed integers.
7485 * alloc.c: Integer signedness and overflow fixes.
7486 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
7487 (__malloc_size_t): Default to size_t, not to int.
7488 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
7489 (Fgarbage_collect, mark_object_loop_halt, mark_object):
7490 Prefer ptrdiff_t to size_t when either would do, as we prefer
7491 signed integers.
7492 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
7493 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
7494 Now const. Initialize with values that are in range even if char
7495 is signed.
7496 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
7497 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
7498 These functions do the right thing with sizes > 2**32.
7499 (check_depth): Now ptrdiff_t, not int.
7500 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
7501 Adjust to new way of storing sizes. Check for size overflow bugs
7502 in rest of code.
7503 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
7504 slightly wrong anyway, as it missed one instance of
7505 XMALLOC_OVERRUN_CHECK_OVERHEAD.
7506 (refill_memory_reserve): Omit needless cast to size_t.
7507 (mark_object_loop_halt): Mark as externally visible.
7509 * xselect.c: Integer signedness and overflow fixes.
7510 (Fx_register_dnd_atom, x_handle_dnd_message):
7511 Use ptrdiff_t, not size_t, since we prefer signed.
7512 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
7513 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
7514 x_dnd_atoms_size and x_dnd_atoms_length.
7516 * doprnt.c: Prefer signed to unsigned when either works.
7517 * eval.c (verror):
7518 * doprnt.c (doprnt):
7519 * lisp.h (doprnt):
7520 * xdisp.c (vmessage):
7521 Use ptrdiff_t, not size_t, when using or implementing doprnt,
7522 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
7523 prefer signed arithmetic to avoid comparison confusion.
7524 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
7525 but is a bit tricky.
7527 Assume freestanding C89 headers, string.h, stdlib.h.
7528 * data.c, doprnt.c, floatfns.c, print.c:
7529 Include float.h unconditionally.
7530 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
7531 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
7532 * regex.c: Likewise for stddef.h, string.h.
7533 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
7534 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
7535 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
7536 (STDC_HEADERS): Remove obsolete defines.
7537 * sysdep.c: Include limits.h unconditionally.
7539 Assume support for memcmp, memcpy, memmove, memset.
7540 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
7541 * regex.c (memcmp, memcpy):
7542 Remove; we assume C89 now.
7544 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
7545 (__malloc_safe_bcopy): Remove; no longer needed.
7547 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
7548 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
7549 well either way, and we prefer signed to unsigned.
7551 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
7553 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
7554 closes the connection while we're reading (bug#9182).
7556 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
7558 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
7559 are specified (Bug#9168).
7561 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
7563 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
7564 Found by GCC static checking and --with-wide-int on a 32-bit host.
7566 2011-07-25 Eli Zaretskii <eliz@gnu.org>
7568 * xdisp.c (compute_display_string_pos): Fix logic of caching
7569 previous display string position. Initialize cached_prev_pos to
7570 -1. Fixes slow-down at the beginning of a buffer.
7572 2011-07-24 Eli Zaretskii <eliz@gnu.org>
7574 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
7575 for attrs[LFACE_FONTSET_INDEX].
7577 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
7579 * xml.c (parse_region): Remove unused local
7580 that was recently introduced.
7582 2011-07-23 Eli Zaretskii <eliz@gnu.org>
7584 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
7585 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
7587 * xdisp.c (move_it_in_display_line_to): Record the best matching
7588 position for TO_CHARPOS while scanning the line, and restore it on
7589 exit if none of the characters scanned was an exact match.
7590 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
7591 when exact match is impossible due to invisible text, and the
7592 lines are truncated.
7594 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
7596 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
7597 for OSX >= 10.7.
7599 2011-07-22 Eli Zaretskii <eliz@gnu.org>
7601 Fix a significant slow-down of cursor motion with C-n, C-p,
7602 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
7603 auto-repeat under bidi redisplay in fontified buffers.
7604 * xdisp.c (compute_stop_pos_backwards): New function.
7605 (next_element_from_buffer): Call compute_stop_pos_backwards to
7606 find a suitable prev_stop when we find ourselves before
7607 base_level_stop.
7608 (reseat): Don't look for prev_stop, as that could mean a very long
7609 run.
7610 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
7611 <cached_disp_overlay_modiff>: Cache for last found display string
7612 position.
7613 (compute_display_string_pos): Return the cached position if asked
7614 about the same buffer in the same area of character positions, and
7615 the buffer wasn't changed since the time the display string
7616 position was cached.
7618 2011-07-22 Eli Zaretskii <eliz@gnu.org>
7620 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
7621 is an integer, which is important for empty lines. (Bug#9149)
7623 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
7625 * frame.c (Fmodify_frame_parameters): In tty case, update the
7626 default face if necessary (Bug#4238).
7628 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
7630 * editfns.c (Fstring_to_char): No need to explain what a character
7631 is in the docstring (Bug#6576).
7633 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
7635 * xml.c (parse_region): Make sure we always return a tree.
7637 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
7639 * xml.c (parse_region): If a document contains only comments,
7640 return that, too.
7642 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
7644 * xml.c (make_dom): Return comments, too.
7646 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
7648 Port to OpenBSD.
7649 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
7650 and the surrounding thread.
7651 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
7652 rather than fgets, and retry after EINTR. Otherwise, 'emacs
7653 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
7654 timer goes off.
7655 * s/openbsd.h (BROKEN_SIGIO): Define.
7656 * unexelf.c (unexec) [__OpenBSD__]:
7657 Don't update the .mdebug section of the Alpha COFF symbol table.
7659 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7661 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
7662 (bug#8460).
7664 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
7666 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
7667 This fixes some race conditions on the permissions of any newly
7668 created file.
7670 * alloc.c (valid_pointer_p): Use pipe, not open.
7671 This fixes some permissions issues when debugging.
7673 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
7674 If fchown fails to set both uid and gid, try to set just gid,
7675 as that is sometimes allowed. Adjust the file's mode to eliminate
7676 setuid or setgid bits that are inappropriate if fchown fails.
7678 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
7680 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
7681 to compare Lisp_Objects.
7682 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
7683 global_gnutls_log_level, don't mistake it for a Lisp_Object.
7684 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
7686 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
7688 * lread.c (read_integer): Unread even EOF character.
7689 (read1): Likewise. Properly record start position of symbol.
7691 * lread.c (read1): Read `#:' as empty uninterned symbol if no
7692 symbol character follows.
7694 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
7696 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
7697 This works around a problem with the previous change to Fcopy_file.
7698 Recent glibc declares fchown with __attribute__((warn_unused_result)),
7699 and without this change, GCC might complain about discarding
7700 fchown's return value.
7702 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
7704 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
7706 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
7708 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
7710 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
7712 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
7713 it's used from the C level.
7715 * process.c: Use the same condition for POLL_FOR_INPUT in both
7716 keyboard.c and process.c (bug#1858).
7718 2011-07-09 Lawrence Mitchell <wence@gmx.li>
7720 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
7721 (Fgnutls_boot): Use it.
7723 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
7725 * doc.c (Fsubstitute_command_keys): Revert last change.
7727 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
7729 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
7730 quotes the next character, and doesn't affect other longer
7731 sequences (bug#8935).
7733 * lread.c (syms_of_lread): Clarify that is isn't only
7734 `eval-buffer' and `eval-defun' that's affected by
7735 `lexical-binding' (bug#8460).
7737 2011-07-15 Eli Zaretskii <eliz@gnu.org>
7739 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
7740 bidi redisplay when a line includes both an image and is truncated.
7742 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
7744 Fix minor problems found by static checking.
7745 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
7746 (elsz): Now a signed constant, not a size_t var. We prefer signed
7747 types to unsigned, to avoid integer comparison confusion. Without
7748 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
7749 "cannot optimize loop, the loop counter may overflow", a symptom
7750 of the confusion.
7751 * indent.c (Fvertical_motion): Mark locals as initialized.
7752 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
7754 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
7756 * search.c (Fre_search_backward): Mention `case-fold-search' in
7757 all the re_search_* functions (bug#8138).
7759 * keyboard.c (Fopen_dribble_file): Document when the file is
7760 closed (bug#8056).
7762 2011-07-14 Eli Zaretskii <eliz@gnu.org>
7764 * bidi.c (bidi_dump_cached_states): Fix format of displaying
7765 bidi_cache_idx.
7767 Support bidi reordering of display and overlay strings.
7768 * xdisp.c (compute_display_string_pos)
7769 (compute_display_string_end): Accept additional argument STRING.
7770 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
7771 (reseat_to_string): Initialize bidi_it->string.s and
7772 bidi_it->string.schars.
7773 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to

7775 Initialize itb.string.lstring.
7776 (init_iterator): Call bidi_init_it only of a valid
7777 buffer position was specified. Initialize paragraph_embedding to
7778 L2R.
7779 (reseat_to_string): Initialize the bidi iterator.
7780 (display_string): If we need to ignore text properties of
7781 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
7782 original value of -1 will not work with bidi.)
7783 (compute_display_string_pos): First arg is now struct
7784 `text_pos *'; all callers changed. Support display properties on
7785 Lisp strings.
7786 (compute_display_string_end): Support display properties on Lisp
7787 strings.
7788 (init_iterator, reseat_1, reseat_to_string): Initialize the
7789 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
7790 when iterating on a string not from display properties).
7791 (compute_display_string_pos, compute_display_string_end):
7792 Fix calculation of the object to scan. Fixes an error when using
7793 arrow keys.
7794 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
7795 base_level_stop; instead, set base_level_stop to BEGV.
7796 Fixes crashes in vertical-motion.
7797 (next_element_from_buffer): Improve commentary for when
7798 the iterator is before prev_stop.
7799 (init_iterator): Initialize bidi_p from the default value of
7800 bidi-display-reordering, not from buffer-local value. Use the
7801 buffer-local value only if initializing for buffer iteration.
7802 (handle_invisible_prop): Support invisible properties on strings
7803 that are being bidi-reordered.
7804 (set_iterator_to_next): Support bidi reordering of C strings and

7807 strings.
7808 (handle_stop_backwards): Support Lisp strings as well.
7809 (display_string): Support display of R2L glyph rows.
7810 Use IT_STRING_CHARPOS when displaying from a Lisp string.
7811 (init_iterator): Don't initialize it->bidi_p for strings
7812 here.
7813 (reseat_to_string): Initialize it->bidi_p for strings here.
7814 (next_element_from_string, next_element_from_c_string)
7815 (next_element_from_buffer): Add xassert's for correspondence

7817 structure.
7818 (face_before_or_after_it_pos): Support bidi iteration.
7819 (next_element_from_c_string): Handle the case of the first string
7820 character that is not the first one in the visual order.
7821 (get_visually_first_element): New function, refactored from common
7822 parts of next_element_from_buffer, next_element_from_string, and
7823 next_element_from_c_string.
7824 (tool_bar_lines_needed, redisplay_tool_bar)
7825 (display_menu_bar): Force left-to-right direction. Add a FIXME
7826 comment for making that be controlled by a user option.
7827 (push_it, pop_it): Save and restore the state of the
7828 bidi iterator. Save and restore the bidi_p flag.
7829 (pop_it): Iterate out of display property for string iteration as

7831 (iterate_out_of_display_property): Support iteration over strings.
7832 (handle_single_display_spec): Set up it->bidi_it for iteration
7833 over a display string, and call bidi_init_it.
7834 (handle_single_display_spec, next_overlay_string)
7835 (get_overlay_strings_1, push_display_prop): Set up the bidi
7836 iterator for displaying display or overlay strings.
7837 (forward_to_next_line_start): Don't use the shortcut if
7838 bidi-iterating.
7839 (back_to_previous_visible_line_start): If handle_display_prop
7840 pushed the iterator stack, restore the internal state of the bidi
7841 iterator by calling bidi_pop_it same number of times.
7842 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
7843 and we are bidi-iterating, don't decrement the iterator position;
7844 instead, set the first_elt flag in the bidi iterator, to produce
7845 the same effect.
7846 (reseat_1): Remove redundant setting of string_from_display_prop_p.
7847 (push_display_prop): xassert that we are iterating a buffer.
7848 (push_it, pop_it): Save and restore paragraph_embedding member.
7849 (handle_single_display_spec, next_overlay_string)
7850 (get_overlay_strings_1, reseat_1, reseat_to_string)
7851 (push_display_prop): Set up the `unibyte' member of bidi_it.string
7852 correctly. Don't assume unibyte strings are not bidi-reordered.
7853 (compute_display_string_pos)
7854 (compute_display_string_end): Fix handling the case of C string.
7855 (push_it, pop_it): Save and restore from_disp_prop_p.
7856 (handle_single_display_spec, push_display_prop): Set the
7857 from_disp_prop_p flag.
7858 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
7859 (pop_it): Call iterate_out_of_display_property only if we are
7860 popping after iteration over a string that came from a display
7861 property. Fix a typo in popping stretch info. Add an assertion
7862 for verifying that the iterator position is in sync with the bidi
7863 iterator.

7865 (push_display_prop): Fix initialization of paragraph direction for
7866 string when that of the parent object is not yet determined.
7867 (reseat_1): Call bidi_init_it to resync the bidi
7868 iterator with IT's position. (Bug#7616)
7869 (find_row_edges): If ROW->start.pos gives position
7870 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
7871 (handle_stop, back_to_previous_visible_line_start, reseat_1):
7872 Reset the from_disp_prop_p flag.
7873 (SAVE_IT, RESTORE_IT): New macros.
7874 (pos_visible_p, face_before_or_after_it_pos)
7875 (back_to_previous_visible_line_start)
7876 (move_it_in_display_line_to, move_it_in_display_line)
7877 (move_it_to, move_it_vertically_backward, move_it_by_lines)
7878 (try_scrolling, redisplay_window, display_line): Use them when
7879 saving a temporary copy of the iterator and restoring it back.
7880 (back_to_previous_visible_line_start, reseat_1)
7881 (init_iterator): Empty the bidi cache "stack".
7882 (move_it_in_display_line_to): If iterator ended up at
7883 EOL, but we never saw any buffer positions smaller than
7884 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
7885 motion in bidi-reordered lines.
7886 (move_it_in_display_line_to): Record prev_method and prev_pos
7887 immediately before the call to set_iterator_to_next. Fixes cursor
7888 motion in bidi-reordered lines with stretch glyphs and strings
7889 displayed in margins. (Bug#8133) (Bug#8867)
7890 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
7891 TO_CHARPOS.
7892 (pos_visible_p): Support positions in bidi-reordered lines.
7893 Save and restore bidi cache.
7895 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
7896 (bidi_paragraph_info): Delete unused struct.
7897 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
7898 (bidi_cache_start): New variable.
7899 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
7900 to zero.
7901 (bidi_cache_fetch_state, bidi_cache_search)
7902 (bidi_cache_find_level_change, bidi_cache_iterator_state)
7903 (bidi_cache_find, bidi_peek_at_next_level)

7931 (bidi_initialize): Initialize the bidi cache start stack pointer.
7932 (bidi_cache_ensure_space): New function, refactored from part of

7946 All variables related to cache indices are now EMACS_INT.
7948 * dispextern.h (struct bidi_string_data): New structure.
7949 (struct bidi_it): New member `string'. Make flag members be 1-bit
7950 fields, and put them last in the struct.
7951 (compute_display_string_pos, compute_display_string_end):
7952 Update prototypes.
7953 (bidi_push_it, bidi_pop_it): Add prototypes.
7954 (struct iterator_stack_entry): New members bidi_p,
7955 paragraph_embedding, and from_disp_prop_p.
7956 (struct it): Member bidi_p is now a bit field 1 bit wide.
7957 (bidi_shelve_cache, bidi_unshelve_cache):
7958 Declare prototypes.
7960 * .gdbinit (xvectype, xvector, xcompiled, xchartable, xboolvector)

8002 (x_handle_selection_clear,x_clear_frame_selections):
8003 Pass Qx_lost_selection_functions rather than
8004 Vx_lost_selection_functions to Frun_hook_with_args.
8006 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
8008 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
8009 The old code sometimes used this field without initializing it.
8011 * alloc.c (gc_sweep): Don't read past end of array.
8012 In theory, the old code could also have corrupted Emacs internals,
8013 though it'd be very unlikely.
8015 2011-07-12 Andreas Schwab <schwab@linux-m68k.org>
8017 * character.c (Fcharacterp): Don't advertise optional ignored
8018 argument. (Bug#4026)
8020 2011-07-12 Lars Magne Ingebrigtsen <larsi@gnus.org>
8022 * keymap.c (syms_of_keymap): Clarify that "modifier" is "modifier
8023 key" (bug#4257).
8025 * window.c (Fset_window_start): Doc fix (bug#4199).
8026 (Fset_window_hscroll): Ditto.
8028 2011-07-12 Paul Eggert <eggert@cs.ucla.edu>

8156 variable firstTime not needed on OSX >= 10.6.

8276 (clone_per_buffer_values): Don't assume that

8278 This isn't true in general, and it's particularly not true
8279 if Emacs is configured with --with-wide-int.
8280 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
8281 New macros, used in the buffer.c change.

8315 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
8317 Random fixes. E.g., (random) never returned negative values.
8318 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
8319 subseconds part to the entropy, as that's a bit more random.
8320 Prefer signed to unsigned, since the signedness doesn't matter and
8321 in general we prefer signed. When given a limit, use a
8322 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
8323 latter isn't right if USE_2_TAGS_FOR_INTS.
8324 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
8325 not 0..VALMASK. Don't discard "excess" bits that random () returns.
8327 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
8329 * textprop.c (text_property_stickiness):
8330 Obey Vtext_property_default_nonsticky.

8335 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
8337 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
8338 This is more efficient than Ffile_directory_p and avoids a minor race.
8340 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
8342 * buffer.c (Foverlay_put): Say what the return value is
8343 (bug#7835).
8345 * fileio.c (barf_or_query_if_file_exists): Check first if the file
8346 is a directory before asking whether to use the file name
8347 (bug#7564).
8348 (barf_or_query_if_file_exists): Make the "File is a directory"
8349 error be more correct.
8351 * fns.c (Frequire): Remove the mention of the .gz files, since
8352 that's installation-specific, but keep the mention of
8353 `get-load-suffixes'.
8355 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
8357 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.
8358 Report string overflow if the output is too long.

8368 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
8369 Also (re)move comments that are misplaced or no longer relevant.
8371 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
8373 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

8398 * lread.c (syms_of_lread): Mention single symbols defined by
8399 `defvar' or `defconst' (bug#7154).
8401 * fns.c (Frequire): Mention .el.gz files (bug#7314).
8402 (Frequire): Mention get-load-suffixes.

8430 minibuffer-local-must-match-map, and
8431 minibuffer-local-filename-must-match-map to Elisp.
8432 (syms_of_keymap): Defsubr make-composed-keymap.
8433 * keyboard.c (menu_bar_items): Use map_keymap_canonical.
8434 (parse_menu_item): Trivial simplification.
8436 2011-07-01 Glenn Morris <rgm@gnu.org>
8438 * Makefile.in (SETTINGS_LIBS): Fix typo.

8455 with value as argument.
8456 (init_gsettings): Check that GSETTINGS_SCHEMA exists before calling

8461 * xgselect.c: Add defined (HAVE_GSETTINGS).
8462 (xgselect_initialize): Ditto.
8464 * process.c: Add defined (HAVE_GSETTINGS) for xgselect.h
8465 (wait_reading_process_output): Add defined (HAVE_GSETTINGS) for
8466 xg_select.
8468 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
8470 * eval.c (struct backtrace): Simplify and port the data structure.
8471 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
8472 signed bit field, as this assumption is not portable and it makes
8473 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
8474 "char debug_on_exit : 1" as this is not portable either; instead,
8475 use the portable "unsigned int debug_on_exit : 1". Remove unused
8476 member evalargs. Remove obsolete comments about cc bombing out.
8478 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

8570 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
8572 Use gnulib's dup2 module instead of rolling our own.

8642 Integer and buffer overflow fixes (Bug#8873).
8644 * print.c (printchar, strout): Check for string overflow.
8645 (PRINTPREPARE, printchar, strout):
8646 Don't set size unless allocation succeeds.
8648 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
8649 for sizes. Check for string overflow more accurately.
8650 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
8652 * macros.c: Integer and buffer overflow fixes.
8653 * keyboard.h (struct keyboard.kbd_macro_bufsize):
8654 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

8660 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
8662 * lread.c: Integer overflow fixes.
8663 (read_integer): Radix is now EMACS_INT, not int,
8664 to improve quality of diagnostics for out-of-range radices.
8665 Calculate buffer size correctly for out-of-range radices.
8666 (read1): Check for integer overflow in radices, and in
8667 read-circle numbers.
8668 (read_escape): Avoid int overflow.
8669 (Fload, openp, read_buffer_size, read1)
8670 (substitute_object_recurse, read_vector, read_list, map_obarray):

8684 (read_escape): Check for hex character overflow.
8686 2011-06-22 Leo Liu <sdl.web@gmail.com>
8688 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
8689 Move to minibuffer.el.
8691 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
8693 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
8694 The following patches are for when GLYPH_DEBUG && !XASSERT.
8695 * dispextern.h (trace_redisplay_p, dump_glyph_string):
8696 * dispnew.c (flush_stdout):
8697 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
8698 Mark as externally visible.
8699 * dispnew.c (check_window_matrix_pointers): Now static.
8700 * dispnew.c (window_to_frame_vpos):
8701 * xfns.c (unwind_create_frame):
8702 * xterm.c (x_check_font): Remove unused local.
8703 * scroll.c (CHECK_BOUNDS):
8704 * xfaces.c (cache_fache): Rename local to avoid shadowing.
8705 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
8706 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
8707 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
8708 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
8709 Now static.
8710 (debug_method_add): Use va_list and vsprintf rather than relying
8711 on undefined behavior with wrong number of arguments.
8712 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
8713 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
8714 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
8715 since we're not interested in debugging glyphs with old libraries.
8716 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
8717 GCC 4.6.0's static checking.
8719 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
8721 Integer overflow and signedness fixes (Bug#8873).

8733 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
8734 (.bitmaps_last):
8735 * xfaces.c (load_pixmap):
8736 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
8737 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
8738 (.bitmaps_last, struct x_output.icon_bitmap):
8739 Use ptrdiff_t, not int, for bitmap indexes.
8740 (x_allocate_bitmap_record): Check for size overflow.
8741 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
8743 Use ptrdiff_t, not int, for overlay counts.

8745 * editfns.c (overlays_around, get_pos_property):
8746 * textprop.c (get_char_property_and_overlay):
8747 * xdisp.c (next_overlay_change, note_mouse_highlight):
8748 * xfaces.c (face_at_buffer_position):
8749 * buffer.c (OVERLAY_COUNT_MAX): New macro.
8750 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
8751 (Fnext_overlay_change, Fprevious_overlay_change)
8752 (mouse_face_overlay_overlaps, Foverlays_in):
8753 Use ptrdiff_t, not int, for sizes.
8754 (overlays_at, overlays_in): Check for size-calculation overflow.
8756 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
8758 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
8759 (x_session_initialize): Do not assume string length fits in int.
8761 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
8762 This is unlikely, but can occur if DPI is outlandish.
8764 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
8765 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
8767 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
8768 * xrdb.c (magic_file_p, search_magic_path):
8769 Omit last arg SUFFIX; it was always 0. All callers changed.
8770 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
8772 * xfont.c (xfont_match): Avoid need for strlen.
8774 * xfns.c: Don't assume strlen fits in int.

8777 * xdisp.c (message_log_check_duplicate): Return intmax_t,
8778 not unsigned long, as we prefer signed integers. All callers changed.
8779 Detect integer overflow in repeat count.
8780 (message_dolog): Don't assume print length fits in 39 bytes.
8781 (display_mode_element): Don't assume strlen fits in int.
8783 * termcap.c: Don't assume sizes fit in int and never overflow.
8784 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
8785 (gobble_line): Check for size-calculation overflow.
8787 * minibuf.c (Fread_buffer):
8788 * lread.c (intern, intern_c_string):
8789 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
8790 Don't assume string length fits in int.

8802 * filelock.c: Fix some buffer overrun and integer overflow issues.
8803 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
8804 Reformulate so as not to need the command string.
8805 Invoke gzip -cd rather than gunzip, as it's more portable.
8806 (lock_info_type, lock_file_1, lock_file):
8807 Don't assume pid_t and time_t fit in unsigned long.
8808 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
8809 (current_lock_owner): Prefer signed type for sizes.
8810 Use memcpy, not strncpy, where memcpy is what is really wanted.
8811 Don't assume (via atoi) that time_t and pid_t fit in int.
8812 Check for time_t and/or pid_t out of range, e.g., via a network share.
8813 Don't alloca where an auto var works fine.
8815 * fileio.c: Fix some integer overflow issues.
8816 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
8817 Don't assume string length fits in int.
8818 (directory_file_name): Don't assume string length fits in long.
8819 (make_temp_name): Don't assume pid fits in int, or that its print
8820 length is less than 20.
8822 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
8824 * coding.c (make_subsidiaries): Don't assume string length fits in int.
8826 * callproc.c (child_setup): Rewrite to avoid two strlen calls.

8840 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
8842 * lread.c (invalid_syntax): Omit length argument.
8843 All uses changed. This doesn't fix a bug, but it simplifies the
8844 code away from its former Hollerith-constant appearance, and it's
8845 one less 'int' to worry about when looking at integer-overflow issues.
8846 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
8848 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
8849 This didn't break anything, but it didn't help either.
8850 It's confusing to put a bogus integer in a place where the actual
8851 value does not matter.
8852 (LIST_END_P): Remove unused macro and its bogus comment.
8853 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
8855 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
8856 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
8857 implementation.
8858 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
8859 We prefer signed types, and the value cannot exceed the EMACS_INT
8860 range anyway (because otherwise the length would not be representable).
8861 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
8862 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
8863 This avoids a GCC warning when WIDE_EMACS_INT.
8865 * indent.c (sane_tab_width): New function.
8866 (current_column, scan_for_column, Findent_to, position_indentation)
8867 (compute_motion): Use it. This is just for clarity.
8868 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
8870 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
8872 * lisp.h (lint_assume): New macro.
8873 * composite.c (composition_gstring_put_cache):
8874 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
8876 * editfns.c, insdel.c:
8877 Omit unnecessary forward decls, to simplify future changes.
8879 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
8881 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
8883 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
8884 Use much-faster test for byte-length change.
8885 Don't assume string byte-length fits in 'int'.
8886 Check that character arg fits in 'int'.
8887 (mapcar1): Declare byte as byte, for clarity.
8889 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
8891 * fns.c (concat): Catch string overflow earlier.
8892 Do not rely on integer wraparound.
8894 * dispextern.h (struct it.overlay_strings_charpos)
8895 (struct it.selective): Now EMACS_INT, not int.
8896 * xdisp.c (forward_to_next_line_start)
8897 (back_to_previous_visible_line_start)
8898 (reseat_at_next_visible_line_start, next_element_from_buffer):
8899 Don't arbitrarily truncate the value of 'selective' to int.
8901 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
8903 * composite.c: Don't truncate sizes to 'int'.
8904 (composition_gstring_p, composition_reseat_it)
8905 (composition_adjust_point): Use EMACS_INT, not int.
8906 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
8907 not EMACS_UINT, for indexes.
8909 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
8911 * buffer.c: Include <verify.h>.
8912 (struct sortvec.priority, struct sortstr.priority):
8913 Now EMACS_INT, not int.
8914 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
8915 (struct sortstr.size, record_overlay_string)
8916 (struct sortstrlist.size, struct sortlist.used):
8917 Don't truncate size to int.
8918 (record_overlay_string): Check for size-calculation overflow.
8919 (init_buffer_once): Check at compile-time, not run-time.
8921 2011-06-22 Jim Meyering <meyering@redhat.com>
8923 Don't leak an XBM-image-sized buffer
8924 * image.c (xbm_load): Free the image buffer after using it.
8926 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
8928 Port to Sun C.
8929 * composite.c (find_automatic_composition): Omit needless 'return 0;'
8930 that Sun C diagnosed.
8931 * fns.c (secure_hash): Fix pointer signedness issue.
8932 * intervals.c (static_offset_intervals): New function.
8933 (offset_intervals): Use it.
8935 2011-06-21 Leo Liu <sdl.web@gmail.com>
8937 * deps.mk (fns.o):
8938 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
8939 sha512.h.
8941 * fns.c (secure_hash): Rename from crypto_hash_function and change
8942 the first arg to accept symbols.
8943 (Fsecure_hash): New primitive.
8944 (syms_of_fns): New symbols.
8946 2011-06-20 Deniz Dogan <deniz@dogan.se>
8948 * process.c (Fset_process_buffer): Clarify return value in
8949 docstring.
8951 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
8953 * dispnew.c (add_window_display_history): Use BVAR.
8955 * xdisp.c (debug_method_add): Use BVAR.
8956 (check_window_end, dump_glyph_matrix, dump_glyph)
8957 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
8959 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
8960 Likewise.
8962 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
8963 check till after the cache is created in init_frame_faces.
8965 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
8967 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
8969 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
8971 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
8972 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
8973 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
8975 Improve buffer-overflow checking (Bug#8873).
8976 * fileio.c (Finsert_file_contents):
8977 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
8978 Remove the old (too-loose) buffer overflow checks.
8979 They weren't needed, since make_gap checks for buffer overflow.
8980 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
8981 The old code merely checked for Emacs fixnum overflow, and relied
8982 on undefined (wraparound) behavior. The new code avoids undefined
8983 behavior, and also checks for ptrdiff_t and/or size_t overflow.
8985 * editfns.c (Finsert_char): Don't dump core with very negative counts.
8986 Tune. Don't use wider integers than needed. Don't use alloca.
8987 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
8989 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
8991 * insdel.c, lisp.h (buffer_overflow): New function.
8992 (insert_from_buffer_1, replace_range, replace_range_2):
8993 * insdel.c (make_gap_larger):
8994 * editfns.c (Finsert_char):
8995 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
8997 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
8999 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
9001 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
9003 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
9004 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
9006 * fileio.c: Don't assume EMACS_INT fits in off_t.
9007 (emacs_lseek): New static function.
9008 (Finsert_file_contents, Fwrite_region): Use it.
9009 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
9011 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
9013 * fns.c: Don't overflow int when computing a list length.
9014 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
9015 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
9016 truncation on 64-bit hosts. Check for QUIT every
9017 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
9018 faster and is responsive enough.
9019 (Flength): Report an error instead of overflowing an integer.
9020 (Fsafe_length): Return a float if the value is not representable
9021 as a fixnum. This shouldn't happen except in contrived situations.
9022 (Fnthcdr, Fsort): Don't assume list length fits in int.
9023 (Fcopy_sequence): Don't assume vector length fits in int.
9025 * alloc.c: Check that resized vectors' lengths fit in fixnums.
9026 (header_size, word_size): New constants.
9027 (allocate_vectorlike): Don't check size overflow here.
9028 (allocate_vector): Check it here instead, since this is the only
9029 caller of allocate_vectorlike that could cause overflow.
9030 Check that the new vector's length is representable as a fixnum.
9032 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
9033 The previous code was bogus. For example, next_almost_prime (32)
9034 returned 39, which is undesirable as it is a multiple of 3; and
9035 next_almost_prime (24) returned 25, which is a multiple of 5 so
9036 why was the code bothering to check for multiples of 7?
9038 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
9040 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
9042 Variadic C functions now count arguments with ptrdiff_t.
9043 This partly undoes my 2011-03-30 change, which replaced int with size_t.
9044 Back then I didn't know that the Emacs coding style prefers signed int.
9045 Also, in the meantime I found a few more instances where arguments
9046 were being counted with int, which may truncate counts on 64-bit
9047 machines, or EMACS_INT, which may be unnecessarily wide.
9048 * lisp.h (struct Lisp_Subr.function.aMANY)
9049 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
9050 Arg counts are now ptrdiff_t, not size_t.
9051 All variadic functions and their callers changed accordingly.
9052 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
9053 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
9054 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
9055 * callint.c (Fcall_interactively): Check arg count for overflow,
9056 to avoid potential buffer overrun. Use signed char, not 'int',
9057 for 'varies' array, so that we needn't bother to check its size
9058 calculation for overflow.
9059 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
9060 * eval.c (apply_lambda):
9061 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
9062 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
9063 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
9065 * callint.c (Fcall_interactively): Don't use index var as event count.
9067 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
9068 * mem-limits.h (SIZE): Remove; no longer used.
9070 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
9072 Remove unnecessary casts.
9073 * xterm.c (x_term_init):
9074 * xfns.c (x_set_border_pixel):
9075 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
9076 These aren't needed now that we assume ANSI C.
9078 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
9079 It's more likely to cause problems (due to unsigned overflow)
9080 than to cure them.
9082 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
9084 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
9086 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
9088 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
9090 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
9092 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
9094 GLYPH_CODE_FACE returns EMACS_INT, not int.
9095 * dispextern.h (merge_faces):
9096 * xfaces.c (merge_faces):
9097 * xdisp.c (get_next_display_element, next_element_from_display_vector):
9098 Don't assume EMACS_INT fits in int.
9100 * character.h (CHAR_VALID_P): Remove unused parameter.
9101 * fontset.c, lisp.h, xdisp.c: All uses changed.
9103 * editfns.c (Ftranslate_region_internal): Omit redundant test.
9105 * fns.c (concat): Minor tuning based on overflow analysis.
9106 This doesn't fix any bugs. Use int to hold character, instead
9107 of constantly refetching from Emacs object. Use XFASTINT, not
9108 XINT, for value known to be a character. Don't bother comparing
9109 a single byte to 0400, as it's always less.
9111 * floatfns.c (Fexpt):
9112 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
9114 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
9115 for characters.
9117 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
9119 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
9120 Without this fix, on a 64-bit host (aset S 0 4294967386) would
9121 incorrectly succeed when S was a string, because 4294967386 was
9122 truncated before it was used.
9124 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
9125 Otherwise, an out-of-range integer could cause undefined behavior
9126 on a 64-bit host.
9128 * composite.c: Use int, not EMACS_INT, for characters.
9129 (fill_gstring_body, composition_compute_stop_pos): Use int, not
9130 EMACS_INT, for values that are known to be in character range.
9131 This doesn't fix any bugs but is the usual style inside Emacs and
9132 may generate better code on 32-bit machines.
9134 Make sure a 64-bit char is never passed to ENCODE_CHAR.
9135 This is for reasons similar to the recent CHAR_STRING fix.
9136 * charset.c (Fencode_char): Check that character arg is actually
9137 a character. Pass an int to ENCODE_CHAR.
9138 * charset.h (ENCODE_CHAR): Verify that the character argument is no
9139 wider than 'int', as a compile-time check to prevent future regressions
9140 in this area.
9142 * character.c (char_string): Remove unnecessary casts.
9144 Make sure a 64-bit char is never passed to CHAR_STRING.
9145 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
9146 by silently ignoring the top 32 bits, allowing some values
9147 that were far too large to be valid characters.
9148 * character.h: Include <verify.h>.
9149 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
9150 arguments are no wider than unsigned, as a compile-time check
9151 to prevent future regressions in this area.
9152 * data.c (Faset):
9153 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
9154 (Fsubst_char_in_region):
9155 * fns.c (concat):
9156 * xdisp.c (decode_mode_spec_coding):
9157 Adjust to CHAR_STRING's new requirement.
9158 * editfns.c (Finsert_char, Fsubst_char_in_region):
9159 * fns.c (concat): Check that character args are actually
9160 characters. Without this test, these functions did the wrong
9161 thing with wildly out-of-range values on 64-bit hosts.
9163 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
9164 These casts should not be needed on 32-bit hosts, either.
9165 * keyboard.c (read_char):
9166 * lread.c (Fload): Remove casts to unsigned.
9168 * lisp.h (UNSIGNED_CMP): New macro.
9169 This fixes comparison bugs on 64-bit hosts.
9170 (ASCII_CHAR_P): Use it.
9171 * casefiddle.c (casify_object):
9172 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
9173 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
9174 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
9175 * dispextern.h (FACE_FROM_ID):
9176 * keyboard.c (read_char): Use UNSIGNED_CMP.
9178 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
9179 not to EMACS_INT, to avoid GCC warning.
9181 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
9183 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
9184 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
9185 isn't needed on 32-bit machines.
9187 * buffer.c (Fgenerate_new_buffer_name):
9188 Use EMACS_INT for count, not int.
9189 (advance_to_char_boundary): Return EMACS_INT, not int.
9191 * data.c (Qcompiled_function): Now static.
9193 * window.c (window_body_lines): Now static.
9195 * image.c (gif_load): Rename local to avoid shadowing.
9197 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
9198 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
9199 * alloc.c (make_save_value): Integer argument is now of type
9200 ptrdiff_t, not int.
9201 (mark_object): Use ptrdiff_t, not int.
9202 * lisp.h (pD): New macro.
9203 * print.c (print_object): Use it.
9205 * alloc.c: Use EMACS_INT, not int, to count objects.
9206 (total_conses, total_markers, total_symbols, total_vector_size)
9207 (total_free_conses, total_free_markers, total_free_symbols)
9208 (total_free_floats, total_floats, total_free_intervals)
9209 (total_intervals, total_strings, total_free_strings):
9210 Now EMACS_INT, not int. All uses changed.
9211 (Fgarbage_collect): Compute overall total using a double, so that
9212 integer overflow is less likely to be a problem. Check for overflow
9213 when converting back to an integer.
9214 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
9215 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
9216 These were 'int' variables that could overflow on 64-bit hosts;
9217 they were never used, so remove them instead of repairing them.
9218 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
9219 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
9220 Previously, this ceilinged at INT_MAX, but that doesn't work on
9221 64-bit machines.
9222 (allocate_pseudovector): Don't use EMACS_INT when int would do.
9224 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
9225 (allocate_vectorlike): Check for ptrdiff_t overflow.
9226 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
9227 when a (possibly-narrower) signed value would do just as well.
9228 We prefer using signed arithmetic, to avoid comparison confusion.
9230 * alloc.c: Catch some string size overflows that we were missing.
9231 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
9232 for convenience in STRING_BYTES_MAX.
9233 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
9234 The definition here is exact; the one in lisp.h was approximate.
9235 (allocate_string_data): Check for string overflow. This catches
9236 some instances we weren't catching before. Also, it catches
9237 size_t overflow on (unusual) hosts where SIZE_MAX <= min
9238 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
9239 and ptrdiff_t and EMACS_INT are both 64 bits.
9241 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
9242 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
9243 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
9245 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
9247 * alloc.c (Fmake_string): Check for out-of-range init.
9249 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
9251 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
9253 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
9255 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
9256 xg_get_default_scrollbar_width.
9258 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
9259 (int_gtk_range_get_value): Move to the scroll bar part of the file.
9260 (style_changed_cb): Call update_theme_scrollbar_width and call
9261 x_set_scroll_bar_default_width and xg_frame_set_char_size for
9262 all frames (Bug#8505).
9263 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
9264 Call gtk_window_set_resizable if HAVE_GTK3.
9265 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
9266 and height if HAVE_GTK3 (Bug#8505).
9267 (scroll_bar_width_for_theme): New variable.
9268 (update_theme_scrollbar_width): New function.
9269 (xg_get_default_scrollbar_width): Move code to
9270 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
9271 (xg_initialize): Call update_theme_scrollbar_width.
9273 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
9275 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
9277 2011-06-12 Martin Rudalics <rudalics@gmx.at>
9279 * frame.c (make_frame): Call other_buffer_safely instead of
9280 other_buffer.
9282 * window.c (temp_output_buffer_show): Call display_buffer with
9283 second argument Vtemp_buffer_show_specifiers and reset latter
9284 immediately after the call.
9285 (Vtemp_buffer_show_specifiers): New variable.
9286 (auto_window_vscroll_p, next_screen_context_lines)
9287 (Vscroll_preserve_screen_position): Remove leading asterisks from
9288 doc-strings.
9290 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
9292 Fix minor problems found by GCC 4.6.0 static checking.
9293 * buffer.c (Qclone_number): Remove for now, as it's unused.
9294 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
9295 (record_buffer): Remove unused local.
9296 * frame.c (other_visible_frames, frame_buffer_list): Now static.
9297 (set_frame_buffer_list): Remove; unused.
9298 * frame.h (other_visible_frames): Remove decl.
9299 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
9300 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
9301 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
9302 if HAVE_GPM.
9303 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
9304 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
9305 Define only if HAVE_GPM.
9306 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
9307 (update_hints_inhibit): Remove; never set. All uses removed.
9308 * widgetprv.h (emacsFrameClassRec): Remove decl.
9309 * window.c (delete_deletable_window): Now returns void, since it
9310 wasn't returning anything.
9311 (compare_window_configurations): Remove unused locals.
9312 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
9313 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
9314 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
9315 the same widths as pointers. This follows up on the 2011-05-06 patch.
9316 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
9317 * xterm.h: Likewise.
9318 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
9320 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
9322 * makefile.w32-in: Update dependencies.
9323 (LISP_H): Add lib/intprops.h.
9325 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
9327 * image.c (gif_load): Add animation frame delay to the metadata.
9328 (syms_of_image): Use DEFSYM. New symbol `delay'.
9330 2011-06-11 Martin Rudalics <rudalics@gmx.at>
9332 * window.c (delete_deletable_window): Re-add.
9333 (Fset_window_configuration): Rewrite to handle dead buffers and
9334 consequently deletable windows.
9335 (window_tree, Fwindow_tree): Remove. Supply functionality in
9336 window.el.
9337 (compare_window_configurations): Simplify code.
9339 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
9341 * image.c (imagemagick_load_image): Fix type mismatch.
9342 (Fimagemagick_types): Likewise.
9344 * window.h (replace_buffer_in_windows): Declare.
9346 2011-06-11 Martin Rudalics <rudalics@gmx.at>
9348 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
9349 Qclone_number. Remove external declaration of Qdelete_window.
9350 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
9351 code.
9352 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
9353 Run Qbuffer_list_update_hook if allowed.
9354 (Fother_buffer): Rewrite doc-string. Major rewrite for new
9355 buffer list implementation.
9356 (other_buffer_safely): New function.
9357 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
9358 calls to replace_buffer_in_windows and
9359 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
9360 if allowed.
9361 (record_buffer): Inhibit quitting and rewrite using quittable
9362 functions. Run Qbuffer_list_update_hook if allowed.
9363 (Frecord_buffer, Funrecord_buffer): New functions.
9364 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
9365 Move switch-to-buffer to window.el.
9366 (bury-buffer): Move to window.el.
9367 (Vbuffer_list_update_hook): New variable.
9369 * lisp.h (other_buffer_safely): Add prototype in buffer.c
9370 section.
9372 * window.h (resize_frame_windows): Move up in code.

9826 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
9827 (bidi_resolve_explicit, bidi_resolve_weak)
9828 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
9829 bidi_it->nchars is non-positive.
9830 (bidi_level_of_next_char): Don't try to lookup the cache for the
9831 next/previous character if nothing is cached there yet, or if we
9832 were just reseat()'ed to a new position.
9834 * xdisp.c (set_cursor_from_row): Set start and stop points
9835 according to the row's direction when priming the loop that looks
9836 for the glyph on which to display cursor.
9837 (single_display_spec_intangible_p): Function deleted.
9838 (display_prop_intangible_p): Reimplement to call
9839 handle_display_spec instead of single_display_spec_intangible_p.
9840 Accept 3 additional arguments needed by handle_display_spec.
9841 This fixes incorrect cursor motion across display property with complex
9842 values: lists, `(when COND...)' forms, etc.
9843 (single_display_spec_string_p): Support property values that are
9844 lists with the argument STRING its top-level element.
9845 (display_prop_string_p): Fix the condition for processing a
9846 property that is a list to be consistent with handle_display_spec.
9847 (handle_display_spec): New function, refactored from the
9848 last portion of handle_display_prop.
9849 (compute_display_string_pos): Accept additional argument
9850 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
9851 value of a `display' property is a "replacing spec".
9852 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
9853 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
9854 the display property, but just return a value indicating whether
9855 the display property will replace the characters it covers.
9856 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
9857 frame_window_p members of struct bidi_it.
9858 (compute_display_string_pos, compute_display_string_end):
9859 New functions.
9860 (push_it): Accept second argument POSITION, where pop_it should
9861 jump to continue iteration.
9862 (reseat_1): Initialize bidi_it.disp_pos.
9864 * keyboard.c (adjust_point_for_property): Adjust the call to
9865 display_prop_intangible_p to its new signature.
9867 * dispextern.h (struct bidi_it): New member frame_window_p.
9868 (bidi_init_it): Update prototypes.
9869 (display_prop_intangible_p): Update prototype.
9870 (compute_display_string_pos, compute_display_string_end):
9871 Declare prototypes.
9872 (struct bidi_it): New members nchars and disp_pos. ch_len is now
9873 EMACS_INT.
9875 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
9877 Malloc failure behavior now depends on size of allocation.
9878 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
9879 * lisp.h: Change signatures accordingly.
9880 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
9881 All callers changed. (Bug#8762)
9883 * gnutls.c: Use Emacs's memory allocators.
9884 Without this change, the gnutls library would invoke malloc etc.
9885 directly, which causes problems on non-SYNC_INPUT hosts, and which
9886 runs afoul of improving memory_full behavior. (Bug#8761)
9887 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
9888 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
9889 xfree instead of the default malloc, realloc, free.
9890 (Fgnutls_boot): No need to check for memory allocation failure,
9891 since xmalloc does that for us.
9893 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
9894 * category.c (hash_get_category_set):
9895 * ccl.c (ccl_driver):
9896 * charset.c (Fdefine_charset_internal):

9899 (composition_gstring_put_cache):
9900 * composite.h (struct composition.hash_index):

9902 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
9903 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
9904 (hashfn_equal, hashfn_user_defined, make_hash_table)
9905 (maybe_resize_hash_table, hash_lookup, hash_put)
9906 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
9907 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
9908 (Fsxhash, Fgethash, Fputhash, Fmaphash):
9909 * image.c (make_image, search_image_cache, lookup_image)
9910 (xpm_put_color_table_h):
9911 * lisp.h (struct Lisp_Hash_Table):
9912 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
9913 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
9914 for hashes and hash indexes, instead of 'unsigned' and 'int'.
9915 * alloc.c (allocate_vectorlike):
9916 Check for overflow in vector size calculations.
9917 * ccl.c (ccl_driver):
9918 Check for overflow when converting EMACS_INT to int.
9919 * fns.c, image.c: Remove unnecessary static decls that would otherwise
9920 need to be updated by these changes.
9921 * fns.c (make_hash_table, maybe_resize_hash_table):
9922 Check for integer overflow with large hash tables.
9923 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
9924 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
9925 (SXHASH_REDUCE): New macro.
9926 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
9927 Use it instead of discarding useful hash info with large hash values.
9928 (sxhash_float): New function.
9929 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
9930 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
9931 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
9932 Rewrite to use FIXNUM_BITS, as this simplifies things.
9933 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
9934 Adjust signatures to match updated version of code.
9935 (consing_since_gc): Now EMACS_INT, since a single hash table can
9936 use more than INT_MAX bytes.
9938 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
9940 Make it possible to build with GCC-4.6+ -O2 -flto.
9942 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
9944 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
9946 * minibuf.c (get_minibuffer, read_minibuf_unwind):
9947 Call minibuffer-inactive-mode.
9949 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
9951 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
9952 Update dependencies.
9954 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9956 * data.c (init_data): Remove code for UTS, this system is not
9957 supported anymore.
9959 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9961 Don't force ./temacs to start in terminal mode.
9963 * frame.c (make_initial_frame): Initialize faces in all cases, not
9964 only when CANNOT_DUMP is defined.
9965 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
9967 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9969 * dispnew.c (add_window_display_history): Use const for the string
9970 pointer. Remove declaration, not needed.
9972 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
9974 Use 'inline', not 'INLINE'.
9975 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
9976 * alloc.c, fontset.c (INLINE): Remove.
9977 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
9978 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
9979 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
9980 * gmalloc.c (register_heapinfo): Use inline unconditionally.
9981 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
9983 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9985 Make it possible to run ./temacs.
9987 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
9988 syms_of_callproc does the same thing. Remove test for
9989 "initialized", do it in the caller.
9990 * emacs.c (main): Avoid calling set_initial_environment when dumping.
9992 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
9994 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
9995 (read_minibuf): Use get_minibuffer.
9996 (syms_of_minibuf): Use DEFSYM.
9997 (Qmetadata): New var.
9998 * data.c (Qbuffer): Don't make it static.
9999 (syms_of_data): Use DEFSYM.
10001 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
10003 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
10004 (CCL_CODE_MIN): New macro.
10006 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
10008 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
10010 * eval.c (Qdebug): Now static.
10011 * lisp.h (Qdebug): Remove decl. This reverts a part of the
10012 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
10013 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
10015 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
10017 * image.c: Various fixes to ImageMagick code comments.
10018 (Fimagemagick_types): Doc fix.
10020 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
10022 Minor fixes prompted by GCC 4.6.0 warnings.
10024 * xselect.c (converted_selections, conversion_fail_tag): Now static.
10026 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
10027 (x_clipboard_manager_save_all): Move extern decl to ...
10028 * xterm.h: ... here, so that it can be checked for consistency.
10030 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
10032 * xselect.c (x_clipboard_manager_save_frame)
10033 (x_clipboard_manager_save_all): New functions.
10034 (Fx_clipboard_manager_save): Lisp function deleted.
10036 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
10037 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
10039 * xterm.h: Update prototype.
10041 2011-05-28 William Xu <william.xwl@gmail.com>
10043 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
10044 exiting (Bug#8239).
10046 2011-05-28 Jim Meyering <meyering@redhat.com>
10048 Avoid a sign-extension bug in crypto_hash_function.
10049 * fns.c (to_uchar): Define.
10050 (crypto_hash_function): Use it to convert some newly-signed
10051 variables to unsigned, to avoid sign-extension bugs. For example,
10052 without this change, (md5 "truc") would evaluate to
10053 45723a2aff78ff4fff7fff1114760e62 rather than the expected
10054 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
10055 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
10057 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10059 Integer overflow fixes.
10061 * dbusbind.c: Serial number integer overflow fixes.
10062 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
10063 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
10064 to hold a serial number that is too large for a fixnum.
10065 (Fdbus_method_return_internal, Fdbus_method_error_internal):
10066 Check for serial numbers out of range. Decode any serial number
10067 that was so large that it became a float. (Bug#8722)
10069 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
10070 (Fdbus_call_method, Fdbus_call_method_asynchronously):
10071 Use XFASTINT rather than XUINT when numbers are nonnegative.
10072 (xd_append_arg, Fdbus_method_return_internal):
10073 (Fdbus_method_error_internal): Likewise. Also, for unsigned
10074 arguments, check that Lisp number is nonnegative, rather than
10075 silently wrapping negative numbers around. (Bug#8722)
10076 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
10077 (Bug#8722)
10079 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
10081 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
10083 ccl: Add integer overflow checks.
10084 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
10085 (IN_INT_RANGE): New macros.
10086 (ccl_driver): Use them to check for integer overflow when
10087 decoding a CCL program. Many of the new checks are whether XINT (x)
10088 fits in int; it doesn't always, on 64-bit hosts. The new version
10089 doesn't catch all possible integer overflows, but it's an
10090 improvement. (Bug#8719)
10092 * alloc.c (make_event_array): Use XINT, not XUINT.
10093 There's no need for unsigned here.
10095 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
10096 This follows up to the 2011-05-06 change that substituted uintptr_t
10097 for EMACS_INT. This case wasn't caught back then.
10099 Rework Fformat to avoid integer overflow issues.
10100 * editfns.c: Include <float.h> unconditionally, as it's everywhere
10101 now (part of C89). Include <verify.h>.
10102 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
10103 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
10104 (Fformat): Avoid the prepass trying to compute sizes; it was only
10105 approximate and thus did not catch overflow reliably. Instead, walk
10106 through the format just once, formatting and computing sizes as we go,
10107 checking for integer overflow at every step, and allocating a larger
10108 buffer as needed. Keep track separately whether the format is
10109 multibyte. Keep only the most-recently calculated precision, rather
10110 than them all. Record whether each argument has been converted to
10111 string. Use EMACS_INT, not int, for byte and char and arg counts.
10112 Support field widths and precisions larger than INT_MAX. Avoid
10113 sprintf's undefined behavior with conversion specifications such as %#d
10114 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
10115 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
10116 formatting out-of-range floating point numbers with int
10117 formats. (Bug#8668)
10119 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
10121 * data.c: Avoid integer truncation in expressions involving floats.
10122 * data.c: Include <intprops.h>.
10123 (arith_driver): When there's an integer overflow in an expression
10124 involving floating point, convert the integers to floating point
10125 so that the resulting value does not suffer from catastrophic
10126 integer truncation. For example, on a 64-bit host (* 4
10127 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
10128 Do not rely on undefined behavior after integer overflow.
10130 merge count_size_as_multibyte, parse_str_to_multibyte
10131 * character.c, character.h (count_size_as_multibyte):
10132 Rename from parse_str_to_multibyte; all uses changed.
10133 Check for integer overflow.
10134 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
10135 since it's now a duplicate of the other. This is more of
10136 a character than a buffer op, so better that it's in character.c.
10137 * fns.c, print.c: Adjust to above changes.
10139 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
10141 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
10143 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10145 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10146 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
10147 (x_clipboard_manager_save): Now static.
10148 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
10150 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10151 (crypto_hash_function): Now static.
10152 Fix pointer signedness problems. Avoid unnecessary initializations.
10154 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
10156 * termhooks.h (Vselection_alist): Make it terminal-local.
10158 * terminal.c (create_terminal): Initialize it.
10160 * xselect.c: Support for clipboard managers.
10161 (Vselection_alist): Move to termhooks.h as terminal-local var.
10162 (LOCAL_SELECTION): New macro.
10163 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
10164 (symbol_to_x_atom): Remove gratuitous arg.
10165 (x_handle_selection_request, lisp_data_to_selection_data)
10166 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
10167 (x_own_selection, x_get_local_selection, x_convert_selection):
10168 New arg, specifying work frame. Use terminal-local Vselection_alist.
10169 (some_frame_on_display): Delete unused function.
10170 (Fx_own_selection_internal, Fx_get_selection_internal)
10171 (Fx_disown_selection_internal, Fx_selection_owner_p)
10172 (Fx_selection_exists_p): New optional frame arg.
10173 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
10174 (x_handle_selection_clear): Don't treat other terminals with the
10175 same keyboard specially. Use the terminal-local Vselection_alist.
10176 (x_clear_frame_selections): Use Frun_hook_with_args.
10178 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
10180 * xterm.h: Add support for those atoms.
10182 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
10184 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
10185 (converted_selections, conversion_fail_tag): New global variables.
10186 (x_selection_request_lisp_error): Free the above.
10187 (x_get_local_selection): Remove unnecessary code.
10188 (x_reply_selection_request): Args changed; handle arbitrary array
10189 of converted selections stored in converted_selections.
10190 Separate the XChangeProperty and SelectionNotify steps.
10191 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
10192 (x_convert_selection): New function.
10193 (x_handle_selection_event): Simplify.
10194 (x_get_foreign_selection): Don't ignore incoming requests while
10195 waiting for an answer; this will fail when we implement
10196 SAVE_TARGETS, and seems unnecessary anyway.
10197 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
10198 (Vx_sent_selection_functions): Doc fix.
10200 2011-05-26 Leo Liu <sdl.web@gmail.com>
10202 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
10204 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10206 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
10208 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
10209 for fringe update if it has periodic bitmap.
10210 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
10211 and fringe_bitmap_periodic_p.
10213 * fringe.c (get_fringe_bitmap_data): New function.
10214 (draw_fringe_bitmap_1, update_window_fringes): Use it.
10215 (update_window_fringes): Record periodicity of fringe bitmap in glyph
10216 row. Mark glyph row for fringe update if periodicity changed.
10218 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
10219 for fringe update unless it has periodic bitmap.
10221 2011-05-25 Kenichi Handa <handa@m17n.org>
10223 * xdisp.c (get_next_display_element): Set correct it->face_id for

10237 * gnutls.c: Remove unused macros.
10238 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
10239 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
10240 Remove macros that are defined and never used.
10241 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
10243 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10245 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
10246 (Fx_get_selection_internal): Minor cleanup.
10247 (Fx_own_selection_internal): Rename arguments for consistency with
10248 select.el.

10258 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10260 * dispnew.c (scrolling_window): Don't exclude the case that the
10261 last enabled row in the desired matrix touches the bottom boundary.
10263 2011-05-21 Glenn Morris <rgm@gnu.org>
10265 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
10266 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
10267 and add some more files.
10269 2011-05-20 Eli Zaretskii <eliz@gnu.org>
10271 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
10272 report_file_error introduced by the change from 2011-05-07.
10274 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
10276 * systime.h (Time): Define only if emacs is defined.
10277 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
10278 where the include path doesn't have X11/X.h by default. See
10279 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
10281 2011-05-20 Kenichi Handa <handa@m17n.org>
10283 * composite.c (find_automatic_composition): Fix previous change.
10285 2011-05-20 Glenn Morris <rgm@gnu.org>
10287 * lisp.mk: New file, split from Makefile.in.
10288 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
10289 (shortlisp): Remove.
10290 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
10292 2011-05-19 Glenn Morris <rgm@gnu.org>
10294 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
10295 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
10296 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
10297 (lisp): Set the order to that of loadup.el.
10298 (shortlisp): Make it a copy of $lisp.
10299 (SOME_MACHINE_LISP): Remove.
10300 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
10301 Use just $shortlisp, not $SOME_MACHINE_LISP too.
10303 2011-05-18 Kenichi Handa <handa@m17n.org>
10305 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
10306 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
10307 (find_automatic_composition): Mostly rewrite for efficiency.
10309 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
10311 * makefile.w32-in: Update dependencies.
10313 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
10315 * menu.c: Include limits.h (fixes the MS-Windows build broken by
10316 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
10318 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
10320 Fix some integer overflow issues, such as string length overflow.
10322 * insdel.c (count_size_as_multibyte): Check for string overflow.
10324 * character.c (lisp_string_width): Check for string overflow.
10325 Use EMACS_INT, not int, for string indexes and lengths; in
10326 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
10327 the resulting string length overflows an EMACS_INT; instead,
10328 report a string overflow if no precision given. When checking for
10329 precision exhaustion, use a check that cannot possibly have
10330 integer overflow. (Bug#8675)
10331 * character.h (lisp_string_width): Adjust to new signature.
10333 * alloc.c (string_overflow): New function.
10334 (Fmake_string): Use it. This doesn't change behavior, but saves
10335 a few bytes and will simplify future changes.
10336 * character.c (string_escape_byte8): Likewise.
10337 * lisp.h (string_overflow): New decl.
10339 Fixups, following up to the user-interface timestamp change.
10340 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
10341 for UI timestamps, instead of unsigned long.
10342 * msdos.c (mouse_get_pos): Likewise.
10343 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
10344 * w32gui.h (Time): Define by including "systime.h" rather than by
10345 declaring it ourselves. (Bug#8664)
10347 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
10348 * image.c (clear_image_cache): Likewise.
10350 * term.c (term_mouse_position): Don't assume time_t wraparound.
10352 Be more systematic about user-interface timestamps.
10353 Before, the code sometimes used 'Time', sometimes 'unsigned long',
10354 and sometimes 'EMACS_UINT', to represent these timestamps.
10355 This change causes it to use 'Time' uniformly, as that's what X uses.
10356 This makes the code easier to follow, and makes it easier to catch
10357 integer overflow bugs such as Bug#8664.
10358 * frame.c (Fmouse_position, Fmouse_pixel_position):
10359 Use Time, not unsigned long, for user-interface timestamps.
10360 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
10361 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
10362 * keyboard.h (last_event_timestamp): Likewise.
10363 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
10364 * menu.h (xmenu_show): Likewise.
10365 * term.c (term_mouse_position): Likewise.
10366 * termhooks.h (struct input_event.timestamp): Likewise.
10367 (struct terminal.mouse_position_hook): Likewise.
10368 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
10369 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
10370 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
10371 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
10372 what it was before.
10373 * menu.h, termhooks.h: Include "systime.h", for Time.
10375 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
10376 Don't assume that the difference between two unsigned long values
10377 can fit into an integer. At this point, we know button_down_time
10378 <= event->timestamp, so the difference must be nonnegative, so
10379 there's no need to cast the result if double-click-time is
10380 nonnegative, as it should be; check that it's nonnegative, just in
10381 case. This bug is triggered when events are more than 2**31 ms
10382 apart (about 25 days). (Bug#8664)
10384 * xselect.c (last_event_timestamp): Remove duplicate decl.
10385 (x_own_selection): Remove needless cast to unsigned long.
10387 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
10388 that always fit in int. Use a sentinel instead of a counter, to
10389 avoid a temp and to allay GCC's concerns about possible int overflow.
10390 * frame.h (struct frame): Use int for menu_bar_items_used
10391 instead of EMACS_INT, since it always fits in int.
10393 * menu.c (grow_menu_items): Check for int overflow.
10395 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
10397 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
10398 Before, the code was not consistent. These values cannot exceed
10399 2**31 - 1 so there's no need to make them unsigned.
10400 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
10401 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
10402 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
10403 as modifiers.
10404 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
10406 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
10407 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
10408 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
10409 presumably because the widths might not match.
10411 * window.c (size_window): Avoid needless test at loop start.
10413 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
10415 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
10417 2011-05-12 Drew Adams <drew.adams@oracle.com>
10419 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
10421 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10423 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
10424 `width' to `bar_area_x' and `bar_area_width', respectively.
10425 (x_scroll_run): Take account of fringe background extension.
10427 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
10428 Rename local vars `left' and `width' to `bar_area_x' and
10429 `bar_area_width', respectively.
10430 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
10431 background extension.
10433 2011-05-10 Jim Meyering <meyering@redhat.com>
10435 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
10437 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
10439 * image.c (Finit_image_library): Return t for built-in image types,
10440 like pbm and xbm. (Bug#8640)
10442 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
10444 * w32menu.c (set_frame_menubar): Fix submenu allocation.
10446 2011-05-07 Eli Zaretskii <eliz@gnu.org>
10448 * w32console.c (Fset_screen_color): Doc fix.
10449 (Fget_screen_color): New function.
10450 (syms_of_ntterm): Defsubr it.
10452 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
10453 unlink the temporary file if Fcall_process didn't create it in the
10454 first place.
10455 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
10456 child process will be redirected to a file specified with `:file'.
10457 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
10458 cue to call_process_cleanup not to close that handle.
10460 2011-05-07 Ben Key <bkey76@gmail.com>
10462 * makefile.w32-in: The bootstrap-temacs rule now makes use of
10463 one of two shell specific rules, either bootstrap-temacs-CMD or
10464 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
10465 to the previous implementation of the bootstrap-temacs rule.
10466 The bootstrap-temacs-CMD rule is similar to the previous
10467 implementation of the bootstrap-temacs rule except that it
10468 makes use of the ESC_CFLAGS variable instead of the CFLAGS
10469 variable.
10471 These changes, along with some changes to nt/configure.bat,
10472 nt/gmake.defs, and nt/nmake.defs, are required to extend my
10473 earlier fix to add support for --cflags and --ldflags options
10474 that include quotes so that it works whether make uses cmd or
10475 sh as the shell.
10477 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
10479 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
10480 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
10481 is a constant.
10482 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
10483 a string. Handle both cases.
10484 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
10485 (Fdbus_register_method): Use Qinvalid_function.
10487 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
10489 * makefile.w32-in: Update dependencies.
10490 (LISP_H): Add inttypes.h and stdin.h.
10491 (PROCESS_H): Add unistd.h.
10493 2011-05-06 Eli Zaretskii <eliz@gnu.org>
10495 * lread.c: Include limits.h (fixes the MS-Windows build broken by
10496 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
10498 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
10500 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
10502 * term.c (vfatal): Remove stray call to va_end.
10503 It's not needed and the C Standard doesn't allow it here anyway.
10505 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
10506 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
10508 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
10509 bytes.
10511 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
10513 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
10515 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
10517 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
10519 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
10521 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
10522 * charset.c (Fdefine_charset_internal): Don't initialize
10523 charset.code_space[15]. The value was garbage, on hosts with
10524 32-bit int (Bug#8600).
10526 * lread.c (read_integer): Be more consistent with string-to-number.
10527 Use string_to_number to do the actual conversion; this avoids
10528 rounding errors and fixes some other screwups. Without this fix,
10529 for example, #x1fffffffffffffff was misread as -2305843009213693952.
10530 (digit_to_number): Move earlier, for benefit of read_integer.
10531 Return -1 if the digit is out of range for the base, -2 if it is
10532 not a digit in any supported base. (Bug#8602)
10534 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
10536 * dispnew.c (scrolling_window): Return 1 if we scrolled,
10537 to match comment at start of function. This also removes a
10538 GCC warning about overflow in a 32+64-bit port.
10540 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
10542 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
10543 Reported by Stefan Monnier in
10544 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
10545 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
10546 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
10548 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
10549 (EMACS_UINTPTR): Likewise, with uintptr_t.
10551 * lisp.h: Prefer 64-bit EMACS_INT if available.
10552 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
10553 on 32-bit hosts that have 64-bit int, so that they can access
10554 large files.
10555 However, temporarily disable this change unless the temporary
10556 symbol WIDE_EMACS_INT is defined.
10558 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
10560 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
10561 This removes an assumption that EMACS_INT and long are the same
10562 width as pointers. The assumption is true for Emacs porting targets
10563 now, but we want to make other targets possible.
10564 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
10565 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
10566 In the rest of the code, change types of integers that hold casted
10567 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
10568 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
10569 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
10570 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
10571 No need to cast type when ORing.
10572 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
10573 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
10574 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
10575 assume EMACS_INT is the same width as char *.
10576 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
10577 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
10578 Remove no-longer-needed casts.
10579 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
10580 (xg_tool_bar_help_callback, xg_make_tool_item):
10581 Use EMACS_INTPTR to hold an integer
10582 that will be cast to void *; this can avoid a GCC warning
10583 if EMACS_INT is not the same width as void *.
10584 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
10585 * xdisp.c (display_echo_area_1, resize_mini_window_1):
10586 (current_message_1, set_message_1):
10587 Use a local to convert to proper width without a cast.
10588 * xmenu.c (dialog_selection_callback): Likewise.
10590 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
10591 Also, don't assume VALBITS / RAND_BITS is less than 5,
10592 and don't rely on undefined behavior when shifting a 1 left into
10593 the sign bit.
10594 * lisp.h (get_random): Change signature to match.
10596 * lread.c (hash_string): Use size_t, not int, for hash computation.
10597 Normally we prefer signed values; but hashing is special, because
10598 it's better to use unsigned division on hash table sizes so that
10599 the remainder is nonnegative. Also, size_t is the natural width
10600 for hashing into memory. The previous code used 'int', which doesn't
10601 retain enough info to hash well into very large tables.
10602 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
10604 * dbusbind.c: Don't possibly lose pointer info when converting.
10605 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
10606 Use XPNTR rather than XHASH, so that the high-order bits of
10607 the pointer aren't lost when converting through void *.
10609 * eval.c (Fautoload): Don't double-shift a pointer.
10611 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
10613 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
10615 * gnutls.c (DEF_GNUTLS_FN):
10616 * image.c (DEF_IMGLIB_FN): Make function pointers static.
10618 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
10620 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
10621 marker. (Bug#8610)
10623 2011-05-05 Eli Zaretskii <eliz@gnu.org>
10625 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
10626 New version that can reserve upto 2GB of heap space.
10628 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
10630 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
10632 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
10634 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
10635 `gnutls_certificate_set_x509_key_file'.
10637 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
10639 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
10640 Update dependencies.
10642 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
10644 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
10645 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
10646 Remove unused parameter `fildes'.
10647 * process.c (read_process_output, send_process): Don't pass it.
10649 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
10651 Fix previous change: the library cache is defined in w32.c.
10652 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
10653 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
10655 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
10657 Implement dynamic loading of GnuTLS on Windows.
10659 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
10660 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
10661 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
10662 Declare.
10664 * gnutls.c (Qgnutls_dll): Define.
10665 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
10666 (gnutls_*): Declare function pointers.
10667 (init_gnutls_functions): New function to initialize function pointers.
10668 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
10669 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
10670 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
10671 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
10672 (emacs_gnutls_write, emacs_gnutls_read)

10694 * process.c: Include lisp.h before w32.h, not after.
10695 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
10696 instead of gnutls_record_check_pending.
10698 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
10700 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
10702 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
10703 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
10704 as passed in.
10706 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
10708 * xterm.c (x_set_frame_alpha): Do not set property on anything

10739 interruptions.
10741 * callproc.c (Fcall_process): Add (:file "file") as an option for
10742 the STDOUT buffer.
10743 (Fcall_process_region): Ditto.
10745 2011-04-30 Eli Zaretskii <eliz@gnu.org>
10747 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
10748 rather than `XVECTOR (FOO)->size'.
10750 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
10751 inttypes.h, as a gnulib replacement is used if it not available in
10752 system headers.
10754 2011-04-21 Eli Zaretskii <eliz@gnu.org>
10756 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
10757 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
10758 of MOST_POSITIVE_FIXNUM. (Bug#8528)
10760 * coding.c (coding_alloc_by_realloc): Error out if destination
10761 will grow beyond MOST_POSITIVE_FIXNUM.
10762 (decode_coding_emacs_mule): Abort if there isn't enough place in
10763 charbuf for the composition carryover bytes. Reserve an extra
10764 space for up to 2 characters produced in a loop.
10765 (decode_coding_iso_2022): Abort if there isn't enough place in
10766 charbuf for the composition carryover bytes.
10768 2011-04-21 Eli Zaretskii <eliz@gnu.org>

10771 aborting when %lld or %lll format is passed.
10772 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
10773 %llo or %llx format is passed. (Bug#8545)
10775 * window.c (window_scroll_line_based): Use a marker instead of
10776 simple variables to record original value of point. (Bug#7952)
10778 * doprnt.c (doprnt): Fix the case where a multibyte sequence
10779 produced by %s or %c overflows available buffer space. (Bug#8545)
10781 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
10783 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
10784 (SIZE_MAX): Move defn after all includes, as they might #define it.
10786 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
10788 * w32.c (init_environment): Warn about defaulting HOME to C:\.

10792 * keyboard.c (Qdelayed_warnings_hook): Define.
10793 (command_loop_1): Run `delayed-warnings-hook'
10794 if Vdelayed_warnings_list is non-nil.
10795 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
10796 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
10798 2011-04-28 Eli Zaretskii <eliz@gnu.org>
10800 * doprnt.c (doprnt): Don't return value smaller than the buffer
10801 size if the message was truncated. (Bug#8545).
10803 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
10805 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
10806 (Fx_window_property): #if-0 the whole functions, not just the bodies.
10808 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
10810 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
10812 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
10814 * makefile.w32-in: Update dependencies.
10816 2011-04-27 Eli Zaretskii <eliz@gnu.org>
10818 Improve `doprnt' and its usage. (Bug#8545)
10819 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
10820 `format_end'. Remove support for %l as a conversion specifier.
10821 Don't use xrealloc. Improve diagnostics when the %l size modifier
10822 is used. Update the commentary.
10824 * eval.c (verror): Simplify calculation of size_t.
10826 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
10827 messages.
10829 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
10831 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
10832 change.
10834 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
10836 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
10837 This makes this file independent of the recent pseudovector change.
10839 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
10841 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
10843 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
10844 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
10845 Remove unused local.
10846 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
10848 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
10849 GCC 4.6.0 optimizes based on type-based alias analysis.
10850 For example, if b is of type struct buffer * and v of type struct
10851 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
10852 != &v->size, and therefore "v->size = 1; b->size = 2; return
10853 v->size;" must therefore return 1. This assumption is incorrect
10854 for Emacs, since it type-puns struct Lisp_Vector * with many other
10855 types. To fix this problem, this patch adds a new type struct
10856 vectorlike_header that documents the constraints on layout of vectors
10857 and pseudovectors, and helps optimizing compilers not get fooled
10858 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
10859 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
10860 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
10861 the size member.
10862 (XSETPVECTYPE): Rewrite in terms of new macro.
10863 (XSETPVECTYPESIZE): New macro, specifying both type and size.
10864 This is a bit clearer, and further avoids the possibility of
10865 undesirable aliasing.
10866 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
10867 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
10868 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
10869 since Lisp_Subr is a special case (no "next" field).
10870 (ASIZE): Now uses header.size rather than size.
10871 All previous uses of XVECTOR (foo)->size replaced to use this macro,
10872 to avoid the hassle of writing XVECTOR (foo)->header.size.
10873 (struct vectorlike_header): New type.
10874 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
10875 object, to help avoid aliasing.
10876 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
10877 (SUBRP): Likewise, since Lisp_Subr is a special case.
10878 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
10879 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
10880 (struct Lisp_Hash_Table): Combine first two members into a single
10881 struct vectorlike_header member. All uses of "size" and "next" members
10882 changed to be "header.size" and "header.next".
10883 * buffer.h (struct buffer): Likewise.
10884 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
10885 * frame.h (struct frame): Likewise.
10886 * process.h (struct Lisp_Process): Likewise.
10887 * termhooks.h (struct terminal): Likewise.
10888 * window.c (struct save_window_data, struct saved_window): Likewise.
10889 * window.h (struct window): Likewise.
10890 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
10891 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
10892 * buffer.c (init_buffer_once): Likewise.
10893 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
10894 special case.
10895 * process.c (Fformat_network_address): Use local var for size,
10896 for brevity.
10898 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
10900 Make the Lisp reader and string-to-float more consistent (Bug#8525)
10901 * data.c (atof): Remove decl; no longer used or needed.
10902 (digit_to_number): Move to lread.c.
10903 (Fstring_to_number): Use new string_to_number function, to be
10904 consistent with how the Lisp reader treats infinities and NaNs.
10905 Do not assume that floating-point numbers represent EMACS_INT
10906 without losing information; this is not true on most 64-bit hosts.
10907 Avoid double-rounding errors, by insisting on integers when
10908 parsing non-base-10 numbers, as the documentation specifies.
10909 * lisp.h (string_to_number): New decl, replacing ...
10910 (isfloat_string): Remove.
10911 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
10912 (read1): Do not accept +. and -. as integers; this
10913 appears to have been a coding error. Similarly, do not accept
10914 strings like +-1e0 as floating point numbers. Do not report
10915 overflow for integer overflows unless the base is not 10 which
10916 means we have no simple and reliable way to continue.
10917 Break out the floating-point parsing into a new
10918 function string_to_number, so that Fstring_to_number parses
10919 floating point numbers consistently with the Lisp reader.
10920 (digit_to_number): Move here from data.c. Make it static inline.
10921 (E_CHAR, EXP_INT): Remove, replacing with ...
10922 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
10923 (string_to_number): New function, replacing isfloat_string.
10924 This function checks for valid syntax and produces the resulting
10925 Lisp float number too. Rework it so that string-to-number
10926 no longer mishandles examples like "1.0e+". Use strtoumax,
10927 so that overflow for non-base-10 numbers is reported only when
10928 there's no portable and simple way to convert to floating point.
10930 * textprop.c (set_text_properties_1): Rewrite for clarity,
10931 and to avoid GCC warning about integer overflow.
10933 * intervals.h (struct interval): Use EMACS_INT for members
10934 where EMACS_UINT might cause problems. See
10935 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
10936 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
10937 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
10938 All uses changed.
10939 (offset_intervals): Tell GCC not to worry about length overflow
10940 when negating a negative length.
10942 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
10943 (overrun_check_free): Likewise.
10945 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
10946 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
10947 word size.
10949 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
10950 (gnutls_make_error): Rename local to avoid shadowing.
10951 (gnutls_emacs_global_deinit): ifdef out; not used.
10952 (Fgnutls_boot): Use const for pointer to readonly storage.
10953 Comment out unused local. Fix pointer signedness problems.
10955 * lread.c (openp): Don't stuff size_t into an 'int'.
10956 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
10957 about possible signed overflow.
10959 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
10960 (GDK_KEY_g): Don't define if already defined.
10961 (xg_prepare_tooltip): Avoid pointer signedness problem.
10962 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
10964 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
10965 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
10967 * xfns.c (Fx_window_property): Simplify a bit,
10968 to make a bit faster and to avoid GCC 4.6.0 warning.
10969 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
10971 * fns.c (internal_equal): Don't assume size_t fits in int.
10973 * alloc.c (compact_small_strings): Tighten assertion a little.
10975 Replace pEd with more-general pI, and fix some printf arg casts.
10976 * lisp.h (pI): New macro, generalizing old pEd macro to other
10977 conversion specifiers. For example, use "...%"pI"d..." rather
10978 than "...%"pEd"...".
10979 (pEd): Remove. All uses replaced with similar uses of pI.
10980 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
10981 * alloc.c (check_pure_size): Don't overflow by converting size to int.
10982 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
10983 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
10984 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
10985 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
10986 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
10987 64-bit hosts.
10988 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
10989 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
10990 * print.c (safe_debug_print, print_object): Likewise.
10991 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
10992 to int.
10993 Use pI instead of if-then-else-abort. Use %p to avoid casts,
10994 avoiding the 0 flag, which is not portable.
10995 * process.c (Fmake_network_process): Use pI to avoid cast.
10996 * region-cache.c (pp_cache): Likewise.
10997 * xdisp.c (decode_mode_spec): Likewise.
10998 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
10999 behavior on 64-bit hosts with printf arg.
11000 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
11001 (x_stop_queuing_selection_requests): Likewise.
11002 (x_get_window_property): Don't truncate byte count to an 'int'
11003 when tracing.
11005 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
11006 here, since it parses constructs like leading '-' and spaces,
11007 which are not wanted; and it overflows with large numbers.
11008 Instead, simply match F[0-9]+, which is what is wanted anyway.
11010 * alloc.c: Remove unportable assumptions about struct layout.
11011 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
11012 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
11013 (allocate_vectorlike, make_pure_vector): Use the new macros,
11014 plus offsetof, to remove unportable assumptions about struct layout.
11015 These assumptions hold on all porting targets that I know of, but
11016 they are not guaranteed, they're easy to remove, and removing them
11017 makes further changes easier.
11019 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
11020 This doesn't fix a bug but makes the code clearer.
11021 (string_overrun_cookie): Now const. Use initializers that
11022 don't formally overflow signed char, to avoid warnings.
11023 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
11024 can cause Emacs to crash when string overrun checking is enabled.
11025 (allocate_buffer): Don't assume sizeof (struct buffer) is a
11026 multiple of sizeof (EMACS_INT); it need not be, if
11027 alignof(EMACS_INT) < sizeof (EMACS_INT).
11028 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
11030 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
11032 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
11034 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
11036 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
11037 supposed to be handshaking. (Bug#8556)
11038 Reported by Paul Eggert <eggert@cs.ucla.edu>.
11040 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
11042 * lisp.h (Qdebug): List symbol.
11043 * eval.c (Qdebug): Restore global linkage.
11044 * keyboard.c (debug-on-event): New variable.
11045 (handle_user_signal): Break into debugger when debug-on-event
11046 matches the current signal symbol.
11048 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
11050 * alloc.c (check_sblock, check_string_bytes)
11051 (check_string_free_list): Convert to standard C.
11053 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
11055 * w32.c (emacs_gnutls_push): Fix typo.
11057 2011-04-25 Eli Zaretskii <eliz@gnu.org>
11059 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
11060 "cast to pointer from integer of different size".
11062 Improve doprnt and its use in verror. (Bug#8545)
11063 * doprnt.c (doprnt): Document the set of format control sequences
11064 supported by the function. Use SAFE_ALLOCA instead of always
11065 using `alloca'.
11067 * eval.c (verror): Don't limit the buffer size at size_max-1, that
11068 is one byte too soon. Don't use xrealloc; instead xfree and
11069 xmalloc anew.
11071 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
11073 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
11074 callbacks stage.
11076 * gnutls.c: Renamed global_initialized to
11077 gnutls_global_initialized. Added internals for the
11078 :verify-hostname-error, :verify-error, and :verify-flags
11079 parameters of `gnutls-boot' and documented those parameters in the
11080 docstring. Start callback support.
11081 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
11082 unless a fatal error occurred. Call gnutls_alert_send_appropriate
11083 on error. Return error code.
11084 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
11085 (emacs_gnutls_read): Likewise.
11086 (Fgnutls_boot): Return handshake error code.

11562 (force_auto_save_soon): Declare only if SIGDANGER.
11563 * xdisp.c (redisplay_window): Simplify code, to make it more
11564 obvious that ignore_mouse_drag_p is not accessed if !defined
11565 USE_GTK && !defined HAVE_NS.
11567 * intervals.c: Make symbols static if they're not exported.

11572 * insdel.c: Make symbols static if they're not exported.
11573 However, leave prepare_to_modify_buffer alone. It's never
11574 called from outside this function, but that appears to be a bug.

11610 * fontset.h (face_suitable_for_char_p): Remove decl.
11611 * xfaces.c (face_at_string_position):
11612 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
11613 since 0 is always ASCII.

11636 * editfns.c, lisp.h (get_operating_system_release): Remove.
11637 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
11638 worth the hassle of breaking this out.
11640 * xterm.c: Make symbols static if they're not exported.

11748 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.

11779 * xdisp.c (message_enable_multibyte): Now static.
11781 Declare Lisp_Object Q* variables to be 'static' if not exported.
11782 This makes it easier for human readers (and static analyzers)
11783 to see whether these variables are used from other modules.
11784 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

11794 Remove decls of unexported vars.
11795 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
11797 * lisp.h (DEFINE_FUNC): Make sname 'static'.
11799 Make Emacs functions such as Fatom 'static' by default.
11800 This makes it easier for human readers (and static analyzers)
11801 to see whether these functions can be called from other modules.
11802 DEFUN now defines a static function. To make the function external
11803 so that it can be used in other C modules, use the new macro DEFUE.
11804 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
11805 (Finit_image_library):
11806 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):

11808 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
11809 Remove decls, since these functions are now static.
11810 (Funintern, Fget_internal_run_time): New decls, since these functions
11811 were already external.
11813 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

11821 Mark functions with DEFUE instead of DEFUN,
11822 if they are used in other modules.
11823 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
11824 decls for now-static functions.
11825 * buffer.h (Fdelete_overlay): Remove decl.

11859 change. (Bug#8496)
11861 2011-04-13 Eli Zaretskii <eliz@gnu.org>
11863 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
11864 when at ZV. (Bug#8487)
11866 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
11868 * charset.c (Fclear_charset_maps): Use xfree instead of free.
11869 (Bug#8437)

11877 (overrun_check_free): Protoize.
11879 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
11881 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
11882 since callers should never pass a negative size.
11883 Change the signature to match that of plain 'read' and 'write'; see
11884 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
11885 * lisp.h: Update prototypes of emacs_write and emacs_read.
11887 2011-04-11 Eli Zaretskii <eliz@gnu.org>
11889 * xdisp.c (redisplay_window): Don't try to determine the character
11890 position of the scroll margin if the window start point w->startp
11891 is outside the buffer's accessible region. (Bug#8468)
11893 2011-04-10 Eli Zaretskii <eliz@gnu.org>
11895 Fix write-region and its subroutines for buffers > 2GB.
11896 * fileio.c (a_write, e_write): Modify declaration of arguments and
11897 local variables to support buffers larger than 2GB.
11898 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
11900 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
11901 argument, local variables, and return value.
11903 * lisp.h: Update prototypes of emacs_write and emacs_read.
11905 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
11907 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
11909 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
11911 Fix more problems found by GCC 4.6.0's static checks.
11913 * xdisp.c (vmessage): Use a better test for character truncation.
11915 * charset.c (load_charset_map): <, not <=, for optimization,
11916 and to avoid potential problems with integer overflow.
11917 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
11918 * casetab.c (set_identity, shuffle): Likewise.
11919 * editfns.c (Fformat): Likewise.
11920 * syntax.c (skip_chars): Likewise.
11922 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
11923 This also lets GCC 4.6.0 generate slightly better loop code.
11925 * callint.c (Fcall_interactively): <, not <=, for optimization.
11926 (Fcall_interactively): Count the number of arguments produced,
11927 not the number of arguments given. This is simpler and lets GCC
11928 4.6.0 generate slightly better code.
11930 * ftfont.c: Distingish more carefully between FcChar8 and char.
11931 The previous code passed unsigned char * to a functions like
11932 strlen and xstrcasecmp that expect char *, which does not
11933 conform to the C standard.
11934 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
11935 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
11936 char * when the C standard requires it.
11938 * keyboard.c (read_char): Remove unused var.
11940 * eval.c: Port to Windows vsnprintf (Bug#8435).
11941 Include <limits.h>.
11942 (SIZE_MAX): Define if the headers do not.
11943 (verror): Do not give up if vsnprintf returns a negative count.
11944 Instead, grow the buffer. This ports to Windows vsnprintf, which
11945 does not conform to C99. Problem reported by Eli Zaretskii.
11946 Also, simplify the allocation scheme, by avoiding the need for
11947 calling realloc, and removing the ALLOCATED variable.
11949 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
11951 Remove invocations of doprnt, as Emacs now uses vsnprintf.
11952 But keep the doprint source code for now, as we might revamp it
11953 and use it again (Bug#8435).
11954 * lisp.h (doprnt): Remove.
11955 * Makefile.in (base_obj): Remove doprnt.o.
11956 * deps.mk (doprnt.o): Remove.
11958 error: Print 32- and 64-bit integers portably (Bug#8435).
11959 Without this change, on typical 64-bit hosts error ("...%d...", N)
11960 was used to print both 32- and 64-bit integers N, which relied on
11961 undefined behavior.
11962 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
11963 * lisp.h (error, verror): Mark as printf-like functions.
11964 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
11965 Report overflow in size calculations when allocating printf buffer.
11966 Do not truncate output string at its first null byte.
11967 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
11968 Truncate the output at a character boundary, since vsnprintf does not
11969 do that.
11970 * charset.c (check_iso_charset_parameter): Convert internal
11971 character to string before calling 'error', since %c now has the
11972 printf meaning.
11973 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
11974 overflow when computing char to be passed to 'error'. Do not
11975 pass Lisp_Object to 'error'; pass the integer instead.
11976 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
11977 formatted with plain %d.
11979 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
11981 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
11983 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.

11993 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
11994 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
11995 return ssize_t not "int", and use size_t as the buffer length.
11996 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
11997 * gnutls.h: Update declarations.
11998 * process.c (read_process_output): Use ssize_t, to match.
11999 (send_process): Likewise.
12001 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12003 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
12005 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12007 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
12008 Use unsigned char, to match FcChar8 type definition.
12010 * xterm.c (handle_one_xevent):
12011 * xmenu.c (create_and_show_popup_menu):
12012 * xselect.c (x_decline_selection_request)

12018 * search.c (string_match_1, fast_string_match)
12019 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
12020 (scan_buffer, find_next_newline_no_quit)
12021 (find_before_next_newline, search_command, Freplace_match)
12022 (Fmatch_data): Make some `int' variables be EMACS_INT.
12024 * xdisp.c (display_count_lines): 3rd argument and return value now
12025 EMACS_INT. All callers changed.
12026 (pint2hrstr): Last argument is now EMACS_INT.

12041 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
12042 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
12043 Declare EMACS_INT.
12044 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
12045 (encode_invocation_designation): Last argument P_NCHARS is now
12046 EMACS_INT.
12047 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
12048 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
12050 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
12051 All users changed.
12053 * ccl.c (Fccl_execute_on_string): Declare some variables
12054 EMACS_INT.
12056 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)

12072 (Qhelp_form_show): New var.
12073 (syms_of_keyboard): Use DEFSYM macro.
12075 * print.c (internal_with_output_to_temp_buffer): Function deleted.

12114 This avoids several warnings with gcc -Wstrict-overflow.
12115 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
12116 directly, rather than having caller test rule sign. This avoids
12117 some unnecessary tests.
12118 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
12119 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
12120 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
12122 * xfont.c (xfont_text_extents): Remove var that was set but not used.
12123 (xfont_open): Avoid unnecessary tests.
12125 * composite.c (composition_gstring_put_cache): Use unsigned integer.
12127 * composite.h, composite.c (composition_gstring_put_cache):
12128 Use EMACS_INT, not int, for length.
12130 * composite.h (COMPOSITION_DECODE_REFS): New macro,
12131 breaking out part of COMPOSITION_DECODE_RULE.
12132 (COMPOSITION_DECODE_RULE): Use it.
12133 * composite.c (get_composition_id): Remove unused local vars,
12134 by using the new macro.
12136 * textprop.c (set_text_properties_1): Change while to do-while,
12137 since the condition is always true at first.
12139 * intervals.c (graft_intervals_into_buffer): Mark var as used.
12140 (interval_deletion_adjustment): Return unsigned value.
12141 All uses changed.

12159 * print.c (print_error_message): Avoid int overflow.
12161 * font.c (font_list_entities): Redo for clarity,
12162 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
12164 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
12165 (font_score): Avoid potential overflow in diff calculation.
12167 * fns.c (substring_both): Remove var that is set but not used.
12168 (sxhash): Redo loop for clarity and to avoid wraparound warning.
12170 * eval.c (funcall_lambda): Rename local to avoid shadowing.
12172 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
12173 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
12174 can always succeed if overflow has undefined behavior.
12176 * search.c (boyer_moore, wordify): Remove vars set but not used.
12177 (wordify): Omit three unnecessary tests.
12179 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

12189 (Finsert_file_contents): Remove unnecessary code checking fd.
12191 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
12192 Check for integer overflow on size calculations.
12194 * buffer.c (Fprevious_overlay_change): Remove var that is set
12195 but not used.
12197 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
12198 Remove vars that are set but not used.
12199 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
12200 (timer_check_2): Mark vars as initialized.
12202 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
12204 * image.c (lookup_image): Remove var that is set but not used.
12205 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
12207 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
12208 that are set but not used.
12210 * xfns.c (make_invisible_cursor): Don't return garbage
12211 if XCreateBitmapFromData fails (Bug#8410).
12213 * xselect.c (x_get_local_selection, x_handle_property_notify):
12214 Remove vars that are set but not used.
12216 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
12217 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
12219 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
12220 Remove var that is set but not used.
12221 (scroll_bar_windows_size): Now size_t, not int.
12222 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
12223 Check for overflow.
12225 * xfaces.c (realize_named_face): Remove vars that are set but not used.
12226 (map_tty_color) [!defined MSDOS]: Likewise.
12228 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
12230 * coding.c: Remove vars that are set but not used.
12231 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
12232 All callers changed.
12233 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
12234 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
12235 (decode_coding_charset): Remove vars that are set but not used.
12237 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
12238 that is set but not used.
12240 * print.c (print_object): Remove var that is set but not used.
12242 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
12243 The gnulib version avoids calling malloc in the usual case,
12244 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
12245 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
12246 * filelock.c (current_lock_owner): Likewise.
12247 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
12248 * sysdep.c: Include allocator.h, careadlinkat.h.
12249 (emacs_no_realloc_allocator): New static constant.
12250 (emacs_readlink): New function.
12251 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
12252 ../lib/careadlinkat.h.
12254 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
12256 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
12257 first non-nil return value).
12259 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
12261 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
12262 if not defined (Bug#8403).

12273 (get_per_char_metric): Remove parameter `f', unused since
12274 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
12276 2011-04-02 Jim Meyering <meyering@redhat.com>
12278 do not dereference NULL upon failed strdup
12279 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
12280 (ns_get_family): Likewise.
12282 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
12284 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
12286 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
12288 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
12289 later (Bug#8403).
12291 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
12293 Add lexical binding.

12305 Mark as dynamic.
12306 (syms_of_lread): Declare `lexical-binding'.
12308 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
12310 * keyboard.c (eval_dyn): New fun.
12311 (menu_item_eval_property): Use it.
12313 * image.c (parse_image_spec): Use Ffunctionp.
12315 * fns.c (concat, mapcar1): Accept byte-code-functions.
12317 * eval.c (Fsetq): Handle lexical vars.
12318 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
12319 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
12320 (FletX, Flet): Obey lexical binding.
12321 (Fcommandp): Handle closures.
12322 (Feval): New `lexical' arg.
12323 (eval_sub): New function extracted from Feval. Use it almost
12324 everywhere where Feval was used. Look up vars in lexical env.
12325 Handle closures.
12326 (Ffunctionp): Move from subr.el.
12327 (Ffuncall): Handle closures.
12328 (apply_lambda): Remove `eval_flags'.
12329 (funcall_lambda): Handle closures and new byte-code-functions.
12330 (Fspecial_variable_p): New function.
12331 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
12332 but without exporting it to Lisp.
12334 * doc.c (Fdocumentation, store_function_docstring):
12335 * data.c (Finteractive_form): Handle closures.
12337 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
12338 interactive spec.
12340 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
12341 New byte-codes.
12342 (exec_byte_code): New function extracted from Fbyte_code to handle new
12343 calling convention for byte-code-functions. Add new byte-codes.

12356 (try_scrolling): Use it when setting scroll_limit.
12357 Limit scrolling to 100 screen lines.
12358 (redisplay_window): Even when falling back on "recentering",
12359 position point in the window according to scroll-conservatively,
12360 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
12362 (try_scrolling): When point is above the window, allow searching
12363 as far as scroll_max, or one screenful, to compute vertical
12364 distance from PT to the scroll margin position. This prevents
12365 try_scrolling from unnecessarily failing when
12366 scroll-conservatively is set to a value slightly larger than the
12367 window height. Clean up the case of PT below the margin at bottom
12368 of window: scroll_max can no longer be INT_MAX. When aggressive
12369 scrolling is in use, don't let point enter the opposite scroll
12370 margin as result of the scroll.
12371 (syms_of_xdisp) <scroll-conservatively>: Document the
12372 threshold of 100 lines for never-recentering scrolling.

12379 (message_log_check_duplicate): Remove parameters `prev_bol' and
12380 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
12381 (redisplay_internal): Remove parameter `preserve_echo_area',
12382 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
12384 * indent.c (Fvertical_motion):
12385 * window.c (window_scroll_pixel_based, Frecenter):
12386 Don't pass `need_y_p' to `move_it_by_lines'.
12388 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
12390 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
12391 steal a few bits to be more compact.
12392 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
12393 Remove unneeded casts.
12395 * bytecode.c (Fbyte_code): CAR and CDR can GC.
12397 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
12399 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
12400 binding" message (bug#7967).
12402 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
12404 Fix more problems found by GCC 4.6.0's static checks.
12406 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
12407 Remove unused local var.
12409 * editfns.c (Fmessage_box): Remove unused local var.
12411 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
12412 (note_mode_line_or_margin_highlight, note_mouse_highlight):
12413 Omit unused local vars.
12414 * window.c (shrink_windows): Omit unused local var.
12415 * menu.c (digest_single_submenu): Omit unused local var.
12416 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
12417 Omit unused local var.
12419 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
12420 Don't assume string length fits in int.
12421 (keyremap_step, read_key_sequence): Use size_t for sizes.
12422 (read_key_sequence): Don't check last_real_key_start redundantly.
12424 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
12425 instead of alloca (Bug#8344).
12427 * eval.c (Fbacktrace): Don't assume nargs fits in int.
12428 (Fbacktrace_frame): Don't assume nframes fits in int.
12430 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
12432 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
12433 concerns.
12435 * term.c (produce_glyphless_glyph): Remove unnecessary test.
12437 * cm.c (calccost): Turn while-do into do-while, for clarity.
12439 * keyboard.c (syms_of_keyboard): Use the same style as later
12440 in this function when indexing through an array. This also
12441 works around GCC bug 48267.
12443 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
12445 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

12448 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
12450 * keyboard.c, keyboard.h (num_input_events): Now size_t.
12451 This avoids undefined behavior on integer overflow, and is a bit
12452 more convenient anyway since it is compared to a size_t variable.
12454 Variadic C functions now count arguments with size_t, not int.
12455 This avoids an unnecessary limitation on 64-bit machines, which
12456 caused (substring ...) to crash on large vectors (Bug#8344).
12457 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.

12465 (funcall_lambda, mark_backtrace): Likewise.
12466 * fns.c (concat): Likewise.
12467 * frame.c (x_set_frame_parameters): Likewise.
12468 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
12469 0 if not found, not -1. All callers changed.
12471 * alloc.c (garbage_collect): Don't assume stack size fits in int.
12472 (stack_copy_size): Now size_t, not int.
12473 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
12475 2011-03-28 Juanma Barranquero <lekktu@gmail.com>

12478 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
12479 All callers changed.
12481 * lisp.h (multibyte_char_to_unibyte):
12482 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
12483 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
12484 * character.h (CHAR_TO_BYTE8):
12485 * cmds.c (internal_self_insert):
12486 * editfns.c (general_insert_function):
12487 * keymap.c (push_key_description):
12488 * search.c (Freplace_match):
12489 * xdisp.c (message_dolog, set_message_1): All callers changed.
12491 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12493 * keyboard.c (safe_run_hook_funcall): New function.
12494 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
12495 don't set the hook to nil, but remove the offending function instead.
12496 (Qcommand_hook_internal): Remove, unused.
12497 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
12498 Vcommand_hook_internal.
12500 * eval.c (enum run_hooks_condition): Remove.
12501 (funcall_nil, funcall_not): New functions.
12502 (run_hook_with_args): Call each function through a `funcall' argument.
12503 Remove `cond' argument, now redundant.
12504 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
12505 (Frun_hook_with_args_until_failure): Adjust accordingly.
12506 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

12512 * print.c (strout): Remove parameter `multibyte', unused since
12513 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
12515 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
12516 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
12517 All callers changed.
12519 * w32.c (_wsa_errlist): Use braces for struct initializers.

12529 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
12530 All callers changed.
12532 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
12534 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

12666 2011-03-23 Julien Danjou <julien@danjou.info>
12668 * term.c (Fsuspend_tty, Fresume_tty):
12669 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
12670 * window.c (temp_output_buffer_show):
12671 * insdel.c (signal_before_change):
12672 * frame.c (Fhandle_switch_frame):
12673 * fileio.c (Fdo_auto_save):
12674 * emacs.c (Fkill_emacs):
12675 * editfns.c (save_excursion_restore):
12676 * cmds.c (internal_self_insert):
12677 * callint.c (Fcall_interactively):
12678 * buffer.c (Fkill_all_local_variables):
12679 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
12680 Use Frun_hooks.
12681 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
12682 unconditionally since it does the check itself.
12684 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
12686 Fix more problems found by GCC 4.5.2's static checks.
12688 * coding.c (encode_coding_raw_text): Avoid unnecessary test
12689 the first time through the loop, since we know p0 < p1 then.
12690 This also avoids a gcc -Wstrict-overflow warning.
12692 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
12693 leading to a memory leak, possible in functions like
12694 load_charset_map_from_file that can allocate an unbounded number
12695 of objects (Bug#8318).
12697 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
12698 that could (at least in theory) be that large.
12700 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
12701 This is less likely to overflow, and avoids undefined behavior if
12702 overflow does occur. All callers changed. Use strtoul to scan
12703 for the unsigned long integer.
12704 (pint2hrstr): Simplify and tune code slightly.
12705 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

12718 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
12720 * process.c (Fmake_network_process): Use socklen_t, not int,
12721 where POSIX says socklen_t is required in portable programs.
12722 This fixes a porting bug on hosts like 64-bit HP-UX, where
12723 socklen_t is wider than int (Bug#8277).
12724 (Fmake_network_process, server_accept_connection):
12725 (wait_reading_process_output, read_process_output):
12726 Likewise.
12728 * process.c: Rename or move locals to avoid shadowing.
12729 (list_processes_1, Fmake_network_process):
12730 (read_process_output_error_handler, exec_sentinel_error_handler):
12731 Rename or move locals.
12732 (Fmake_network_process): Define label "retry_connect" only if needed.
12733 (Fnetwork_interface_info): Fix pointer signedness.
12734 (process_send_signal): Add cast to avoid pointer signedness problem.
12735 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
12736 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
12738 Make tparam.h and terminfo.c consistent.
12739 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
12740 Include tparam.h instead, since it declares them.
12741 * cm.h (PC): Remove extern decl; tparam.h now does this.
12742 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
12743 * terminfo.c: Include tparam.h, to check interfaces.
12744 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
12745 (tparam): Adjust signature to match interface in tparam.h;
12746 this removes some undefined behavior. Check that outstring and len
12747 are zero, which they always are with Emacs.
12748 * tparam.h (PC, BC, UP): New extern decls.
12750 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
12751 (xftfont_open): Rename locals to avoid shadowing.
12753 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
12754 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
12755 (OTF_TAG_SYM): Omit macro if not needed.
12756 (ftfont_list): Remove unused local.
12757 (get_adstyle_property, ftfont_pattern_entity):
12758 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
12759 Rename locals to avoid shadowing.
12761 * xfont.c (xfont_list_family): Mark var as initialized.
12763 * xml.c (make_dom): Now static.
12765 * composite.c (composition_compute_stop_pos): Rename local to
12766 avoid shadowing.
12767 (composition_reseat_it): Remove unused locals.
12768 (find_automatic_composition, composition_adjust_point): Likewise.
12769 (composition_update_it): Mark var as initialized.
12770 (find_automatic_composition): Mark vars as initialized,
12771 with a FIXME (Bug#8290).
12773 character.h: Rename locals to avoid shadowing.
12774 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
12775 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
12776 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
12777 (BUF_DEC_POS): Be more systematic about renaming local temporaries
12778 to avoid shadowing.
12780 * textprop.c (property_change_between_p): Remove; unused.
12782 * intervals.c (interval_start_pos): Now static.
12784 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

12787 Rename locals to avoid shadowing.
12789 * sound.c (wav_play, au_play, Fplay_sound_internal):
12790 Fix pointer signedness.
12791 (alsa_choose_format): Remove unused local var.
12792 (wav_play): Initialize a variable to 0, to prevent undefined
12793 behavior (Bug#8278).
12795 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
12797 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
12799 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
12800 clobbering (Bug#8298).
12801 * sysdep.c (sys_subshell): Likewise.
12802 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
12804 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
12805 This should get cleaned up, so that child_setup has the
12806 same signature on all platforms.
12808 * callproc.c (call_process_cleanup): Now static.
12809 (relocate_fd): Rename locals to avoid shadowing.
12811 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
12813 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
12814 not to be necessary, and produces flickering.
12816 2011-03-20 Glenn Morris <rgm@gnu.org>
12818 * config.in: Remove file.
12820 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

12828 * minibuf.c (completing-read-function): New variable.
12829 (completing-read-default): Rename from completing-read.
12830 (completing-read): Call completing-read-function.
12832 2011-03-19 Juanma Barranquero <lekktu@gmail.com>

12934 * lisp.h (get_system_name, get_operating_system_release):
12935 Move decls here, to check interfaces.
12936 * process.c (get_operating_system_release): Move decl to lisp.h.
12937 * xrdb.c (get_system_name): Likewise.

12939 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
12940 some of which prompt warnings from gcc -Wbad-function-cast.
12941 (Fformat_time_string, Fencode_time, Finsert_char):
12942 (Ftranslate_region_internal, Fformat):

12970 (Fmemory_limit): Cast sbrk's returned value to char *.

12977 Use functions, not macros, for up- and down-casing (Bug#8254).
12978 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
12979 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
12980 to use the following functions instead of these macros.
12981 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
12982 EMACS_INT, since callers assume the returned value fits in int.
12983 (upcase1): Likewise, for UPCASE_TABLE.
12984 (uppercasep, lowercasep, upcase): New static inline functions.
12985 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

12991 (regex_compile, re_search_2, re_match_2_internal):
12992 Remove unused local vars.

12995 (regex_compile, re_match_2_internal): Mark locals as initialized.
12996 (RETALLOC_IF): Define only if needed.
12997 (WORDCHAR_P): Likewise. This one is never needed, but is used
12998 only in a comment talking about a compiler bug, so put inside
12999 the #if 0 of that comment.
13000 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
13001 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

13014 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
13016 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
13017 All uses changed.
13018 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
13019 Rename locals to avoid shadowing.
13020 (Fvertical_motion): Mark locals as initialized.
13022 * casefiddle.c (casify_object, casify_region): Now static.

13027 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
13028 New macros, so that the caller can use some names other than
13029 gcpro1, gcpro2, etc.
13030 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
13031 of the new macros.
13032 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
13033 argument, for consistency with GCPRO2_VAR, etc: it is now the
13034 prefix of the variable, not the variable itself. All uses
13035 changed.
13036 * dired.c (directory_files_internal, file_name_completion):
13037 Rename locals to avoid shadowing.
13039 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
13040 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
13041 dired.c's scmp function, had undefined behavior.
13042 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13043 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
13044 * buffer.h: ... to here, because these macros use current_buffer,
13045 and the new implementation with inline functions needs to have
13046 current_buffer in scope now, rather than later when the macros
13047 are used.
13048 (downcase, upcase1): New static inline functions.
13049 (DOWNCASE, UPCASE1): Reimplement using these functions.
13050 This avoids undefined behavior in expressions like
13051 DOWNCASE (x) == DOWNCASE (y), which previously suffered
13052 from race conditions in accessing the global variables
13053 case_temp1 and case_temp2.
13054 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
13055 * lisp.h (case_temp1, case_temp2): Remove their decls.
13056 * character.h (ASCII_CHAR_P): Move from here ...
13057 * lisp.h: ... to here, so that the inline functions mentioned
13058 above can use them.
13060 * dired.c (directory_files_internal_unwind): Now static.
13062 * fileio.c (file_name_as_directory, directory_file_name):
13063 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
13064 Now static.
13065 (file_name_as_directory): Use const pointers when appropriate.
13066 (Fexpand_file_name): Likewise. In particular, newdir might
13067 point at constant storage, so make it a const pointer.
13068 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
13069 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
13070 signedness issues.
13071 (Fset_file_times, Finsert_file_contents, auto_save_error):
13072 Rename locals to avoid shadowing.
13074 * minibuf.c (choose_minibuf_frame_1): Now static.
13075 (Ftry_completion, Fall_completions): Rename or remove locals
13076 to avoid shadowing.
13078 * marker.c (bytepos_to_charpos): Remove; unused.
13080 * lisp.h (verify_bytepos, count_markers): New decls,
13081 so that gcc does not warn that these functions aren't declared.
13083 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
13084 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
13085 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
13086 (copy_text): Remove unused local var.
13088 * filelock.c (within_one_second): Now static.
13089 (lock_file_1): Rename local to avoid shadowing.
13091 * buffer.c (fix_overlays_before): Mark locals as initialized.
13092 (fix_start_end_in_overlays): Likewise. This function should be
13093 simplified by using pointers-to-pointers, but that's a different
13094 matter.
13095 (switch_to_buffer_1): Now static.
13096 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
13097 (report_overlay_modification): Rename locals to avoid shadowing.
13099 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
13100 Fix pointer signedness issue.
13101 (sys_subshell): Mark local as volatile if checking for lint,
13102 to suppress a gcc -Wclobbered warning that does not seem to be right.
13103 (MAXPATHLEN): Define only if needed.
13105 * process.c (serial_open, serial_configure): Move decls from here ...
13106 * systty.h: ... to here, so that they can be checked.
13108 * fns.c (get_random, seed_random): Move extern decls from here ...
13109 * lisp.h: ... to here, so that they can be checked.
13111 * sysdep.c (reset_io): Now static.
13112 (wait_for_termination_signal): Remove; unused.
13114 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
13115 (copy_keymap_item, append_key, push_text_char_description):
13116 Now static.
13117 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
13118 (DENSE_TABLE_SIZE): Remove; unused.
13119 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
13120 (describe_map_tree):
13121 Rename locals to avoid shadowing.
13123 * keyboard.c: Declare functions static if they are not used elsewhere.
13124 (echo_char, echo_dash, cmd_error, top_level_2):
13125 (poll_for_input, handle_async_input): Now static.
13126 (read_char, kbd_buffer_get_event, make_lispy_position):

13128 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
13129 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
13130 (Fread_key_sequence_vector): Rename locals to avoid shadowing.

13140 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
13141 (DEFINE_DUMMY_FUNCTION): New macro.
13142 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
13143 Use it.
13144 (main): Add casts to avoid warnings
13145 if GCC considers string literals to be constants.
13147 * lisp.h (fatal_error_signal): Add decl, since it's exported.

13150 (xd_signature, xd_append_arg, xd_initialize):
13151 (Fdbus_call_method, Fdbus_call_method_asynchronously):
13152 (Fdbus_method_return_internal, Fdbus_method_error_internal):

13197 * w32term.c (Vwindow_system, updating_frame):
13198 * w32uniscribe.c (initialized, uniscribe_font_driver):
13199 Remove unneeded extern declarations.
13201 2011-03-14 Chong Yidong <cyd@stupidchicken.com>

13270 For example, without this patch (encode-time 0 0 0 1 1
13271 1152921504606846976) returns the obviously-bogus value (-948597
13272 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
13273 reports time overflow. See
