458 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
459 * nsterm.m (ns_term_init):
460 Avoid the need for strncpy, by using build_string or
461 make_unibyte_string directly. Use dtoastr, not snprintf.
462 * process.c (Fmake_network_process): Diagnose service names that
463 are too long, rather than silently truncating them or creating
464 non-null-terminated names.
465 (Fnetwork_interface_info): Likewise, for interface names.
466 * sysdep.c (system_process_attributes) [GNU_LINUX]:
467 Prefer sprintf to strncat.

494 Optimize pure C strings initialization.
495 * lisp.h (make_pure_string): Fix prototype.
496 (build_pure_c_string): New function, defined as static inline. This
497 provides a better opportunity to optimize away calls to strlen when
498 the function is called with compile-time constant argument.
499 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
500 argument, adjust users accordingly. Use build_pure_c_string where
501 appropriate.
502 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
503 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
504 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
506 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
508 Avoid calls to strlen in miscellaneous functions.

517 srclen argument and return the length of result. Adjust users
518 accordingly.
519 (directory_file_name): Fix comment. Change to add srclen argument,
520 swap 1st and 2nd arguments to obey the common convention. Adjust
521 users accordingly.

530 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
531 * s/gnu.h (DATA_START): Move definitions to configure.
533 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
534 We include usg5-4-common.h, which defines them both.
536 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
537 O_RDONLY already includes it).
539 Stop ns builds setting the EMACSLOADPATH environment variable.
540 * nsterm.m (ns_load_path): Rename from ns_init_paths.
541 Now it does not set EMACSLOADPATH, just returns the load-path string.

543 * lread.c [HAVE_NS]: Include nsterm.h.
544 (init_lread) [HAVE_NS]: Use ns_load_path.

547 2012-07-09 Glenn Morris <rgm@gnu.org>
549 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
550 since the included bsd-common.h does so.
552 Stop ns builds setting the EMACSPATH environment variable.
553 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
554 (ns_init_paths): Do not set EMACSPATH.
555 * nsterm.h (ns_exec_path): Add it.
556 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
557 Use ns_exec_path.
559 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
561 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
563 * process.c (wait_reading_process_output): 'waitchannels' was unset
564 when read_kbd || !NILP (wait_for_cell); fix this.
566 Add GCC-style 'const' attribute to functions that can use it.
567 * character.h (char_resolve_modifier_mask):
568 * keyboard.h (make_ctrl_char):
569 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

578 Add decls with ATTRIBUTE_CONST.
580 Minor improvements to make_formatted_string.
581 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
582 where int is good enough, as vsprintf returns an int.
583 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
585 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
587 Use make_formatted_string to avoid double length calculation.

612 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
614 Move marker debugging code under MARKER_DEBUG.
615 * marker.c (MARKER_DEBUG): Move marker debugging code under
616 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
617 for bootstrap with --enable-checking (~3x slowdown reported
618 by Juanma Barranquero <lekktu@gmail.com>).
619 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
621 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
623 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.

630 (display_line): Add commentary about displaying truncation glyphs
631 on GUI frames.
632 (produce_special_glyphs): Move here from term.c.
634 * term.c (produce_special_glyphs): Move to xdisp.c.
636 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
637 section.
639 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
641 * xdisp.c (display_line): Avoid warning about implicit declaration
642 of FRAME_FONT.
644 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
646 * lisp.h: Remove empty conditional.
648 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
650 * lread.c (load_path_check): Now static.
652 Fix some minor --with-ns problems found by static checking.
653 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
654 (x_set_font) [!HAVE_X_WINDOWS]:
655 * image.c (xpm_load_image) [HAVE_NS]:
656 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
657 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
658 Remove unused local.

660 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
661 * image.c (x_create_bitmap_from_file) [HAVE_NS]:

664 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
665 Fix pointer signedness problem.
666 * xfaces.c (FRAME_X_FONT_TABLE):
667 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
669 2012-07-07 Glenn Morris <rgm@gnu.org>
671 * lread.c (load_path_check): New function, split from init_lread.
672 (init_lread): Reorganize. Motivation:
673 If EMACSLOADPATH is set, check/warn about that rather than the
674 defaults, which we are not going to use. Hence we can remove
675 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
676 Don't warn if site-lisp directories are missing.
677 If not installed, start from a blank load-path, since
678 PATH_LOADSEARCH refers to the eventual installation directories.
680 2012-07-07 Eli Zaretskii <eliz@gnu.org>
682 Support truncation and continuation glyphs on GUI frames, when
683 fringes are disabled. (Bug#11832)
684 * xdisp.c (init_iterator): Get dimensions of truncation and
685 continuation glyphs even if on GUI frames. Adjust
686 it->last_visible_x on GUI frames when the left or right fringes,
687 or both, are absent.
688 (start_display, move_it_in_display_line_to): Handle the case of a
689 GUI frame without a fringe to display continuation or truncation
690 glyphs.
691 (insert_left_trunc_glyphs): Support GUI frames: make sure
692 truncation glyphs overwrite enough glyphs from the current line to
693 have sufficient space in pixels.
694 (display_line): Support truncation and continuation glyphs on GUI
695 frames. If some spare pixels are left on the line after inserting
696 the truncation glyphs, fill that space with a stretch glyph of a
697 suitably computed width.
699 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
700 produce_glyphs, to support GUI sessions.
702 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
704 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
706 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
708 Do not require float-time's arg to fit in time_t (Bug#11825).
709 This works better on hosts where time_t is unsigned, and where
710 float-time is applied to the (negative) difference between two times.
711 * editfns.c (decode_time_components): Last arg is now double *,
712 not int *, and means to store all the result as a double, without
713 worrying about whether the seconds part fits in time_t.
714 All callers changed.
715 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
716 All callers changed.
717 (Ffloat_time): Do not fail merely because the specified time falls
718 outside of time_t range.

729 Update dependencies.
731 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
733 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
735 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

737 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
738 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
739 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
740 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
742 * xfont.c (compare_font_names): Redo to omit the need for casts.
744 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
746 * xfns.c (Fx_change_window_property): Doc fix.
747 * w32fns.c (Fx_change_window_property): Doc fix.
749 * w32fns.c (Fx_window_property): Accept the same arguments as the
750 X Windows version. Doc fix.
751 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
753 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
754 Eli Zaretskii <eliz@gnu.org>
756 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
757 Windows-specific code from nt/config.nt moved here.
758 Obsolete settings removed.
760 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
762 * process.c: Avoid unnecessary calls to gettime.
763 (wait_reading_process_output): Don't get the time of day
764 when gobbling data immediately and not waiting, as there's no need
765 for it in that case. This removes a FIXME.
767 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
769 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
770 is defined (Bug#11768).
772 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
774 Fix marker debugging code.
775 * marker.c (byte_char_debug_check): Do not perform the check
776 if buffer is not multibyte.
777 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
778 Call byte_char_debug_check with correct arguments.
780 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
782 Compile marker debugging code only if ENABLE_CHECKING is defined.
783 * marker.c (byte_char_debug_check, count_markers):
784 Use only if ENABLE_CHECKING is defined.
785 (byte_debug_flag): Remove.
786 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
787 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
789 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
791 Avoid code repetition in marker-related functions.
792 * marker.c (attach_marker): New function.
793 (Fset_marker, set_marker_restricted, set_marker_both)
794 (set_marker_restricted_both): Use it.
795 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
796 Consistently rename charno to charpos.
797 (marker_position): Add eassert.
798 (marker_byte_position): Convert to eassert.

822 to avoid redundant calls to unchain_overlay.
823 * buffer.c (drop_overlay): New function.
824 (delete_all_overlays, Fdelete_overlay): Use it.
825 * minibuf.c (get_minibuffer): Fix comment.
827 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
829 Port to OpenBSD 5.1 amd64.
830 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
831 This is needed for OpenBSD, and should be harmless on all BSD systems.
832 Also, include <sys/sysctl.h>, as it should be available on all
833 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
834 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
835 use p_pid member, not kp_proc.pid.
837 2012-07-06 Glenn Morris <rgm@gnu.org>
839 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
841 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
843 More xmalloc and related cleanup.
844 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
845 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
846 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:
847 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
848 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
849 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
850 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:

852 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
853 * xterm.c:
854 Omit needless casts involving void * pointers and allocation.
855 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
856 as the former is more robust if P's type is changed.
857 Prefer xzalloc to xmalloc + memset 0.
858 Simplify malloc-or-realloc to realloc.
859 Don't worry about xmalloc returning a null pointer.
860 Prefer xstrdup to xmalloc + strcpy.
861 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
862 growing it.
863 * keyboard.c (apply_modifiers_uncached): Prefer local array to
864 alloca of a constant.
866 2012-07-05 Eli Zaretskii <eliz@gnu.org>
868 * xdisp.c (display_line): Fix horizontal pixel coordinates when
869 hscroll is larger than the line width. Fixes long and futile
870 looping inside extend_face_to_end_of_line (on a TTY) producing
871 glyphs that are not needed and thrown away.
873 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
875 * marker.c (set_marker_restricted_both): Simplify by using
876 clip_to_bounds.
878 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
880 * editfns.c (region_limit): Simplify by using clip_to_bounds.

901 * xdisp.c (window_hscroll_limited): New function.
902 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
903 coordinates when window's hscroll is set to insanely large

969 * fileio.c (time_error_value): Check the right error number.
970 Problem reported by Troels Nielsen in
971 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
973 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
975 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
976 This should be fixed in a better way; see Eli Zaretskii in
977 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
978 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
980 * fileio.c (time_error_value): Rename from special_mtime.
981 The old name's problems were noted by Eli Zaretskii in
982 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
984 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
985 This variable's comment says Emacs needs at least one GDB-visible
986 symbol of type enum pvec_type, to work around GDB problems.
987 The symbol's value doesn't matter.
989 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
990 that causes compilation to fail on pre-C99 compilers.
992 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
994 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
995 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
997 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
999 * buffer.c (init_buffer_once): Fix initialization of
1000 headers for buffer_defaults and buffer_local_symbols.
1001 Reported by Juanma Barranquero <lekktu@gmail.com>.
1003 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
1005 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
1006 * lisp.h (enum pvec_type): Use fewer bits.
1007 (PSEUDOVECTOR_SIZE_BITS): New constant.
1008 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
1009 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
1010 change in pvec_type.
1011 (PSEUDOVECTOR_TYPEP): New macro.
1012 (TYPED_PSEUDOVECTORP): Use it.
1013 * fns.c (internal_equal): Adapt code to extract pvectype.
1014 * emacs.c (gdb_pvec_type): Update type.
1015 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
1016 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
1017 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
1018 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
1019 (sweep_vectors): Use it. Use local var `total_bytes' instead of
1020 abusing vector->header.next.nbytes.
1021 (live_vector_p): Use PVEC_TYPE.
1022 (mark_object): Adapt code to extract pvectype. Use switch.
1024 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1026 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
1027 Tighten new eassert a bit.
1029 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1031 Fix compilation with --enable-gcc-warnings and -O1
1032 optimization level.
1033 * doprnt.c (doprnt): Change type of tem to int, initialize
1034 to avoid compiler warning. Add eassert.
1035 * search.c (simple_search): Initialize match_byte to avoid
1036 compiler warning. Add eassert.
1038 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1040 Avoid weird behavior with large horizontal scrolls.
1041 Without this change, for example, large hscroll values would
1042 mess up Emacs's display on Fedora 15 x86, presumably due to
1043 overflows in int calculations in the display code.
1044 Also, if buffers had long lines, Emacs would freeze.
1045 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
1046 (set_window_hscroll): New function, containing the old guts of
1047 Fset_window_hscroll. Return the clipped value.
1048 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
1049 This avoids the need to check against PTRDIFF_MAX.
1051 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
1053 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1055 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
1057 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1059 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
1060 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
1061 since GCC 4.4.6 issues a bogus warning for them.
1063 Fix bugs in file timestamp newness comparisons.
1064 * fileio.c (Ffile_newer_than_file_p):
1065 * lread.c (Fload): Use full timestamp resolution of files,
1066 not just the 1-second resolution, so that files that are only
1067 slightly newer still count as newer.
1068 * fileio.c (Ffile_newer_than_file_p): Don't assume file
1069 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
1071 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
1073 * fileio.c: Improve handling of file time marker. (Bug#11852)
1074 (special_mtime): New function.
1075 (Finsert_file_contents, Fverify_visited_file_modtime):
1076 Use it to set special mtime values consistently.
1078 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
1080 * fileio.c (Finsert_file_contents): Properly handle st_mtime
1081 marker for non-existing file. (Bug#11852)
1083 2012-07-03 Glenn Morris <rgm@gnu.org>
1085 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
1086 and did not make it into globals.h).
1088 2012-07-03 Tom Tromey <tromey@redhat.com>
1090 * window.c (Fset_window_margins, Fset_window_fringes)
1091 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
1092 * textprop.c (Fprevious_property_change): No longer static.

1094 * process.c (Fget_process, Fprocess_datagram_address): No longer
1095 static.
1096 * keymap.c (Flookup_key, Fcopy_keymap): No longer static.
1097 * keyboard.c (Fcommand_execute): No longer static.
1098 Remove EXFUN.

1116 * fontset.h: Remove EXFUN.
1117 * font.h: Remove EXFUNs.
1118 * dosfns.c (system_process_attributes): Remove EXFUN.
1119 * keymap.h: Remove EXFUNs.
1120 * lisp.h: Remove EXFUNs.
1121 * w32term.h: Remove EXFUNs.
1122 * window.h: Remove EXFUNs.
1123 * xsettings.h: Remove EXFUN.
1124 * xterm.h: Remove EXFUN.
1126 2012-07-03 Glenn Morris <rgm@gnu.org>
1128 * lisp.h (Frandom): Make it visible to C.
1129 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
1130 buffer for invisible buffers. (Bug#1229)
1132 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1134 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
1135 values which aren't power of 2.
1136 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
1137 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
1138 accordingly.
1140 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
1142 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
1144 * alloc.c (mark_object): Revert part of last patch to use `switch'.
1146 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1148 * alloc.c (allocate_vector_block): Remove redundant
1149 calls to mallopt if DOUG_LEA_MALLOC is defined.
1150 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
1151 avoid calls to mallopt if zero_vector is returned.
1153 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1155 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
1156 is enabled, avoid dereferencing NULL current_sblock if
1157 running undumped.
1159 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1161 Cleanup basic buffer management.
1162 * buffer.h (struct buffer): Change layout to use generic vector
1163 marking code. Fix some comments. Change type of 'clip_changed'
1164 to bitfield. Remove unused #ifndef old.
1165 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
1166 (GET_OVERLAYS_AT): Fix indentation.
1167 (for_each_per_buffer_object_at): New macro.

1176 (mark_object): Use it. Adjust marking of misc objects
1177 and related comments.
1179 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
1181 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
1182 wrapper that is not needed because the wrapped code is a no-op (zero
1183 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
1184 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
1186 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
1188 * alloc.c (mark_buffer): Simplify. Remove prototype.
1189 (mark_object): Add comment. Reorganize marking of vector-like
1190 objects. Use CHECK_LIVE for all vector-like objects except buffers
1191 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
1192 redundant calls to mark_vectorlike for bool vectors.
1194 2012-06-30 Glenn Morris <rgm@gnu.org>
1196 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
1198 * epaths.in (PATH_SITELOADSEARCH): New.
1199 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
1200 This is rather than relying on --enable-locallisppath elements
1201 having "site-lisp" in their names. (Bug#10208#25, 11658)
1203 2012-06-30 Eli Zaretskii <eliz@gnu.org>
1205 * w32proc.c (sys_select): Accept and ignore one more argument.
1207 * w32.c (emacs_gnutls_pull): Call select with one more argument.
1209 * sysselect.h [DOS_NT]: Don't include sys/select.h.
1210 (pselect) [!MS_DOS]: Redirect to sys_select.
1212 * sysdep.c: Don't include dos.h and dosfns.h.
1214 * process.c (sys_select):
1215 * msdos.c (sys_select): Accept one more argument and ignore it.
1217 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
1218 adapt data types and code to that.
1220 * dosfns.c:
1221 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
1222 which clashes with the gnulib function of the same name.
1224 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
1226 * font.c (font_style_to_value, font_style_symbolic)
1227 (font_prop_validate_style): Add type checks for values in
1228 font_style_table.
1230 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
1231 argument.
1232 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
1233 uses.
1235 2012-06-29 Eli Zaretskii <eliz@gnu.org>
1237 * xdisp.c (try_window_id): Undo last change.
1239 * w32.c (getwd): Adjust commentary about startup_dir.
1240 (init_environment): Always call sys_access, even in non-MSVC
1241 builds. Don't chdir to the directory of the Emacs executable.
1242 This undoes code from 1997 which was justified by the need to
1243 "avoid conflicts when removing and renaming directories". But its
1244 downside was that every relative file name was being interpreted
1245 relative to the directory of the Emacs executable, which can never
1246 be TRT. In particular, it broke sys_access when called with
1247 relative file names.
1248 (sys_access): Map GetLastError to errno.
1250 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1252 * window.h (struct window): Change type of 'fringes_outside_margins'
1253 to bitfield. Fix comment. Adjust users accordingly.

1255 Adjust comment.
1256 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
1257 to ptrdiff_t.
1259 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
1261 * gnutls.c (emacs_gnutls_handshake):
1262 Add QUIT to make the loop interruptible.
1264 2012-06-29 Glenn Morris <rgm@gnu.org>
1266 * charset.c (init_charset): Make lack of etc/charsets fatal.
1268 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1270 * editfns.c (region_limit): Fix type mismatch.
1272 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1274 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
1275 undefined. Convert from xassert to eassert.
1276 * nsmenu.m: Convert from xassert to eassert.
1277 * nsterm.m: Likewise.
1279 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
1281 * editfns.c (region_limit): Clip to narrowing (bug#11770).
1283 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
1285 Avoid integer overflow on scroll-left and scroll-right.
1286 * window.c (HSCROLL_MAX): New macro.
1287 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
1288 overflow when requested scroll falls outside ptrdiff_t range.
1290 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
1292 * window.h (struct window): Change type of 'hscroll',
1293 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
1294 'last_modified' and 'last_overlay_modified' to EMACS_INT.
1295 Adjust users accordingly.
1296 * xdisp.c (try_cursor_movement): Replace type check with eassert.
1297 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
1298 from EMACS_INT to ptrdiff_t.
1299 (make_window): Omit redundant initialization.
1301 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
1303 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
1305 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
1307 * window.h (struct window): Change type of 'use_time' and
1308 'sequence_number' from Lisp_Object to int.

1317 enabled with --enable-checking=[all,glyphs] configure option.
1318 Fix GLYPH_DEBUG usage assuming that it may be undefined,
1319 adjust comments accordingly.

1361 2012-06-27 Stefan Monnier <monnier@iro.umontreal.ca>
1363 * fns.c (maybe_resize_hash_table): Output message when growing the
1364 purify-hashtable.
1366 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
1368 * alloc.c (allocate_string_data): Remove dead code.
1369 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
1370 avoid GCC warning about unused macro.
1372 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
1374 * alloc.c (allocate_string): Omit intervals initialization.
1375 * alloc.c (make_uninit_multibyte_string): Initialize intervals

1398 on Mac OS X Lion: __mod_init_func and __mod_term_func.
1400 * alloc.c (mark_memory): Do not check with -faddress-sanitizer
1401 when building with Clang.
1403 2012-06-26 Stefan Monnier <monnier@iro.umontreal.ca>
1405 * eval.c (Fapply): Allow calling it with a single argument.
1407 2012-06-26 Eli Zaretskii <eliz@gnu.org>
1409 * s/ms-w32.h (strcasecmp, strncasecmp) [_MSC_VER]: Redirect to
1410 _stricmp and _strnicmp.

1432 * alloc.c: Remove build_string.
1433 * lisp.h: Define build_string as static inline. This provides
1434 a better opportunity to optimize away calls to strlen when the
1435 function is called with compile-time constant argument.
1436 * image.c (imagemagick_error): Convert to build_string.
1437 * w32proc.c (sys_spawnve): Likewise.
1438 * xterm.c (x_term_init): Likewise.
1440 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
1442 Use sprintf return value instead of invoking strlen on result.
1443 In the old days this wasn't portable, since some sprintf
1444 implementations returned char *. But they died out years ago and
1445 Emacs already assumes sprintf returns int.
1446 Similarly for float_to_string.
1447 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
1448 * ccl.c (ccl_driver):
1449 * character.c (string_escape_byte8):

1452 * print.c (print_object):
1453 * xdisp.c (message_dolog):
1454 * xfns.c (syms_of_xfns):
1455 Use sprintf or float_to_string result to avoid need to call strlen.
1456 * data.c (Fnumber_to_string):
1457 Use make_unibyte_string, since the string must be ASCII.
1458 * lisp.h, print.c (float_to_string): Now returns int length.
1459 * term.c (produce_glyphless_glyph):
1460 Use sprintf result rather than recomputing it.
1462 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
1463 * Makefile.in (ALL_CFLAGS):
1464 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
1465 * gmalloc.c, regex.c: Include <config.h> unconditionally.
1467 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
1469 * dispextern.h (xstrcasecmp): Define to library function
1470 strcasecmp if available.
1471 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
1473 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
1475 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):
1476 Avoid comma operator.

1484 to memset.
1486 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
1488 * gtkutil.c (get_utf8_string): Remove redundant assignment.
1489 sprintf already null-terminates its output.
1491 * xfns.c (x_window): Remove redundant cast.
1493 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
1495 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
1496 `const char *' to `char *' to avoid compiler warning.
1498 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
1500 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
1501 instead of truncating it to 63 (admittedly a generous limit).
1503 * process.c: Fix spelling and caps in comments.
1505 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
1507 * emacs.c (setpgrp): Remove definition, unused.

1552 No need for separate decl merely because of _Noreturn.
1553 * sound.c (sound_warning, parse_sound):
1554 Remove unnecessary forward decls.
1556 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
1558 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
1559 * lisp.h (WAIT_READING_MAX): New macro.
1560 * dispnew.c (Fsleep_for, sit_for):
1561 * keyboard.c (kbd_buffer_get_event):
1562 * process.c (Faccept_process_output):
1563 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
1564 This improves on the previous patch, which introduced a bug
1565 when time_t is unsigned and as wide as intmax_t.
1566 See <http://bugs.gnu.org/9000#51>.
1568 2012-06-23 Eli Zaretskii <eliz@gnu.org>
1570 * dispnew.c (sit_for, Fsleep_for):
1571 * keyboard.c (kbd_buffer_get_event):
1572 * process.c (Faccept_process_output): Avoid compiler warnings when

1584 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
1585 Privately reported by Herbert J. Skuhra.
1586 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
1587 All uses changed.
1588 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
1589 not make_lisp_timeval, when the argument is of type EMACS_TIME.
1591 2012-06-23 Eli Zaretskii <eliz@gnu.org>
1593 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
1594 last argument of make_unibyte_string.
1596 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
1597 language ID in the event parameters.
1599 * w32term.c (w32_read_socket): Put the new keyboard codepage into
1600 event.code, not the obscure "character set ID".
1602 2012-06-23 Chong Yidong <cyd@gnu.org>
1604 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

1623 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
1624 Privately reported by Herbert J. Skuhra.
1625 [__FreeBSD__]: Remove "*/" typo after "#include".
1626 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
1627 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
1628 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
1629 Don't assume EMACS_TIME and struct timeval are the same type.
1631 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
1633 Support higher-resolution time stamps (Bug#9000).
1634 The time stamps are only nanosecond-resolution at the C level,
1635 since that's the best that any real-world system supports now.
1636 But they are picosecond-resolution at the Lisp level, as that's
1637 easy, and leaves room for future OS improvements.
1639 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
1640 (LIBES): Use it.
1642 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
1643 Don't get current time unless it's needed.
1645 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
1646 now provides it if it's absent.
1647 (start_atimer): Port to higher-res time stamps.
1648 Check for time stamp overflow. Don't get current time more
1649 often than is needed.
1651 * buffer.h (struct buffer): Buffer modtime now has high resolution.
1652 Include systime.h, not time.h.
1653 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
1655 * dired.c: Include stat-time.h.
1656 (Ffile-attributes): File times now have higher resolution.
1658 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
1659 (struct image): Timestamp now has higher resolution.
1661 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
1662 has at least microseconds now. All uses removed.
1663 (update_frame, update_single_window, update_window, update_frame_1)
1664 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
1666 * editfns.c (time_overflow): Now extern.
1667 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
1668 (float-time, Fformat_time_string, Fcurrent_time_string)
1669 (Fcurrent_time_zone): Accept and generate higher-resolution
1670 time stamps.
1671 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
1672 (decode_time_components, lisp_seconds_argument): New functions.
1673 (make_time): Now static.
1674 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
1675 Report an error if the time is invalid, rather than having the caller
1676 do that.
1678 * fileio.c: Include <stat-time.h>
1679 (Fcopy_file): Copy higher-resolution time stamps.
1680 Prefer to set the time stamp via a file descriptor if that works.
1681 (Fset_file_times, Finsert_file_contents, Fwrite_region)
1682 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
1683 (Fvisited_file_modtime, Fset_visited_file_modtime):
1684 Support higher-resolution time stamps.
1686 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
1688 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
1690 * image.c (prepare_image_for_display, clear_image_cache)
1691 (lookup_image): Port to higer-resolution time stamps.
1693 * keyboard.c (start_polling, bind_polling_period):
1694 Check for time stamp overflow.
1695 (read_char, kbd_buffer_get_event, timer_start_idle)
1696 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
1697 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
1698 Port to higher-resolution time stamps. Do not assume time_t is signed.
1699 (decode_timer): New function. Timers are now vectors of length 9,
1700 not 8, to accommodate the picosecond component.
1701 (timer_check_2): Use it.
1703 * nsterm.m (select_timeout, timeval_subtract): Remove.
1704 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
1705 as they're a bit more accurate and handle overflow better.
1706 (ns_select): Change prototype to be compatible with pselect.
1707 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
1708 * nsterm.h (ns_select): Adjust prototype.
1710 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
1711 us-resolution time stamps.
1712 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
1714 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
1716 * lisp.h (time_overflow): New decl.
1717 (wait_reading_process_output): First arg is now intmax_t, not int,
1718 to accommodate larger waits.
1720 * process.h (struct Lisp_Process.read_output_delay):
1721 Now counts nanoseconds, not microseconds.
1722 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
1723 EMACS_HAS_USECS.
1724 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
1725 (wait_reading_process_output):
1726 Port to ns-resolution time stamps.
1727 (Faccept_process_output, wait_reading_process_output):
1728 Check for time stamp overflow. Do not assume time_t is signed.
1729 (select_wrapper): Remove; we now use pselect.
1730 (Fprocess_attributes): Now generates ns-resolution time stamps.
1732 * sysdep.c: Include utimens.h. Don't include utime.h
1733 or worry about struct utimbuf; gnulib does that for us now.
1734 (gettimeofday): Remove; gnulib provides a substitute.
1735 (make_timeval): New function.
1736 (set_file_times): Now sets ns-resolution time stamps.
1737 New arg FD; all uses changed.
1738 (time_from_jiffies, ltime_from_jiffies, get_up_time)
1739 (system_process_attributes):
1740 Now returns ns-resolution time stamp. All uses changed.
1741 Check for time stamp overflow.
1743 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
1744 provides a substitute now.
1746 * systime.h: Include timespec.h rather than sys/time.h and time.h,
1747 since it guarantees struct timespec.
1748 (EMACS_TIME): Now struct timespec, so that we can support
1749 ns-resolution time stamps.
1750 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
1751 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
1752 (EMACS_USECS): Remove.
1753 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
1754 so multiply the arg by 1000 before storing it.
1755 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
1756 New macros.
1757 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
1758 Port to ns-resolution time stamps.
1759 (EMACS_TIME_NEG_P): Remove; replaced by....
1760 (EMACS_TIME_SIGN): New macro.
1761 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
1762 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
1763 (set_file_times, make_time, lisp_time_argument): Adjust signature.
1764 (make_timeval, make_lisp_time, decode_time_components): New decls.
1765 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
1766 that it mishandled time_t overflow. You can't compare by subtracting!
1767 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
1768 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
1770 * term.c: Include <sys/time.h>.
1771 (timeval_to_Time): New function, for proper overflow wraparound.
1772 (term_mouse_position, term_mouse_click): Use it.
1774 * undo.c (record_first_change): Support higher-resolution time stamps
1775 in the undo buffer.
1776 (Fprimitive_undo): Use them when restoring time stamps.
1778 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
1779 (w32_get_internal_run_time):
1780 Port to higher-resolution Emacs time stamps.
1781 (ltime): Now accepts single 64-bit integer, as that's more convenient
1782 for callers.
1784 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
1786 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
1787 for compatibility with pselect. Support ns-resolution time stamps.
1789 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
1791 * xselect.c (wait_for_property_change, x_get_foreign_selection):
1792 Check for time stamp overflow, and support ns-resolution time stamps.
1794 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
1795 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
1796 (timeval_subtract): Remove; no longer needed.
1797 (XTflash, XTring_bell, x_wait_for_event):
1798 Port to ns-resolution time stamps. Don't assume time_t is signed.
1800 2012-06-22 Chong Yidong <cyd@gnu.org>
1802 * xdisp.c (x_consider_frame_title): Revert last change.
1804 2012-06-22 Eli Zaretskii <eliz@gnu.org>
1806 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
1807 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
1808 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
1809 staticidx goes up to 1597 out of 1600 = 0x640.)
1811 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
1813 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
1814 Otherwise, the umask might be mistakenly 0 while handling input signals.
1816 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
1818 * minibuf.c (Fread_string): Bind minibuffer-completion-table.
1820 2012-06-19 Dmitry Antipov <dmantipov@yandex.ru>
1822 * alloc.c, bytecode.c, ccl.c, coding.c, composite.c, data.c, dosfns.c:
1823 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
1824 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
1825 access to `contents' member of Lisp_Vector objects with AREF and ASET
1826 where appropriate.
1828 2012-06-19 Chong Yidong <cyd@gnu.org>
1830 * frame.c (delete_frame): When selecting a frame on a different
1831 text terminal, do not alter the terminal's top-frame.
1833 * xdisp.c (format_mode_line_unwind_data): Record the target
1834 frame's selected window and its terminal's top-frame.
1835 (unwind_format_mode_line): Restore them.
1836 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
1837 Callers changed.
1838 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
1839 since tty frames can be explicitly named.
1840 (prepare_menu_bars): Likewise.
1842 * term.c (Ftty_top_frame): New function.
1844 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
1846 Port byte-code-meter to modern targets.
1847 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
1848 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
1849 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
1850 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
1851 (METER_1, METER_2): Simplify.
1853 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

1857 2012-06-18 Martin Rudalics <rudalics@gmx.at>
1859 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
1860 gets killed during executing of this function (Bug#11665).
1861 Try to always return Qt when the buffer has been actually killed.
1862 (Vkill_buffer_query_functions): In doc-string say that functions
1863 run by this hook should not change the current buffer.
1865 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
1867 Fix recently-introduced process.c problems found by static checking.

1887 * lisp.h (eassert): Assume C89 or later.
1888 This removes the need for CHECK.

1890 argument were confusing, as 'eassert' typically does not evaluate
1891 its argument.
1893 * coding.c (produce_chars): Use ptrdiff_t, not int.
1895 * xterm.c (x_draw_underwave): Check for integer overflow.
1896 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

1989 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
1990 If all the glyphs of the glyph row came from strings, and we have no
1991 cursor positioning clues, put the cursor on the first glyph of the
1992 row.

2069 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
2070 * alloc.c (make_number) [!defined make_number]:

2082 as the union type is for debugging, not for production.
2083 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
2084 Use an inline function on all platforms when using the union type,
2085 since this is simpler and 'static inline' can be used portably
2086 within Emacs now.
2087 (LISP_INITIALLY_ZERO): New macro.
2088 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.

2176 2012-06-08 Eli Zaretskii <eliz@gnu.org>
2178 * dispnew.c (showing_window_margins_p): Undo last change, which

2220 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
2221 (init_alloc_once): Add call to init_vectors.
2223 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
2225 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
2227 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
2229 * doprnt.c (doprnt): Truncate multibyte char correctly.
2230 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
2231 would mishandle a string argument "Xc" if X was a multibyte
2232 character of length 2: it would truncate after X's first byte
2233 rather than including all of X.
2235 2012-06-06 Chong Yidong <cyd@gnu.org>
2237 * buffer.c (word_wrap): Doc fix.

2286 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
2287 Convert pctcpu and pctmem to Lisp float properly.
2288 Let the compiler fold better, as 100.0/0x8000 is exact.
2290 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
2292 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
2293 cons_block.

2302 bitfields where appropriate, remove unused fields.
2303 * window.h (struct window): Remove unused 'last_mark_x' and
2304 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
2305 change it's type from Lisp_Object to bitfield.
2306 Change type of 'force_start', 'optional_new_start',
2307 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
2308 fields from Lisp_Object to bitfield. Adjust users accordingly.
2310 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2312 Pacify gcc -Wdouble-precision when using Xaw.
2313 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
2314 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
2315 Use 'float' consistently, rather than 'float' in most places
2316 and 'double' in a couple of places.
2318 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2320 * xdisp.c (handle_stop): Detect whether we have overlay strings
2321 loaded by testing it->current.overlay_string_index to be
2322 non-negative, instead of checking whether n_overlay_strings is
2323 positive. (Bug#11587)
2325 2012-05-31 Chong Yidong <cyd@gnu.org>
2327 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
2329 * doc.c (Fsubstitute_command_keys): Doc fix.
2331 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2333 * search.c (search_buffer): Remove calls to
2334 r_alloc_inhibit_buffer_relocation, as it is now called by
2335 maybe_unify_char, which was the cause of relocation of buffer text
2336 in bug#11519.
2338 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2340 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
2341 for the duration of call to load_charset, to avoid problems with
2342 callers of maybe_unify_char that access buffer text through C
2343 pointers.
2345 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
2346 decrement the inhibition flag, instead of just setting or
2347 resetting it.
2349 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2351 Remove obsolete '#define static' cruft.
2352 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
2353 This #undef was "temporary" in 2000; it is no longer needed
2354 now that '#define static' has gone away.
2355 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
2356 (gray_bitmap_bits): Remove; no longer needed.
2357 All uses replaced with definiens.
2358 * xterm.c: Include "bitmaps/gray.xbm".
2360 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
2362 Clean up __executable_start, monstartup when --enable-profiling.
2363 The following changes affect the code only when profiling.
2364 * dispnew.c (__executable_start): Rename from safe_bcopy.
2365 Define only on platforms that need it.
2366 * emacs.c: Include <sys/gmon.h> when profiling.
2367 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
2368 (__executable_start): Remove decl, since lisp.h does it now.
2369 (safe_bcopy): Remove decl; no longer has that name.
2370 (main): Coalesce #if into single bit of code, for simplicity.
2371 Cast pointers to uintptr_t, since standard libraries want integers
2372 and not pointers.
2373 * lisp.h (__executable_start): New decl.
2375 2012-05-31 Glenn Morris <rgm@gnu.org>
2377 * image.c (Fimagemagick_types): Doc fix.
2379 2012-05-30 Jim Meyering <meyering@redhat.com>
2381 * callproc.c (Fcall_process_region): Include directory component
2382 in mkstemp error message (Bug#11586).
2384 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
2386 * alloc.c, lisp.h (make_pure_vector): Now static.
2388 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
2390 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
2391 Move to byte-run.el.
2392 (Fautoload): Do the hash-doc more carefully.
2393 * data.c (Fdefalias): Purify definition, except for keymaps.
2394 (Qdefun): Move from eval.c.
2395 * lisp.h (Qdefun): Remove.
2396 * lread.c (read1): Tiny simplification.
2398 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
2400 Do not create empty overlays with the evaporate property (Bug#9642).
2401 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
2402 Bug#9642, but explicitly check that the buffer the overlay would
2403 be moved to is live and rearrange lines to make sure that errors
2404 will not put the overlay in an inconsistent state.
2405 (Fdelete_overlay): Cosmetics.
2407 2012-05-28 Eli Zaretskii <eliz@gnu.org>
2409 * w32term.c (my_bring_window_to_top): New function.
2410 (x_raise_frame): Use handle returned by DeferWindowPos, which
2411 could be different from the original one.
2412 Call my_bring_window_to_top instead of my_set_foreground_window.
2413 (Bug#11513)
2415 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
2416 by calling BringWindowToTop.
2418 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
2419 (WM_EMACS_END): Increase by one.
2421 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
2423 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
2424 This avoids undefined behavior that might cause the eassert
2425 to not catch an out-of-range value.
2427 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
2429 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
2430 Update dependencies.
2432 2012-05-27 Eli Zaretskii <eliz@gnu.org>
2434 * bidi.c (bidi_mirror_char): Fix last change.
2436 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
2438 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
2439 when referring to sectname field in printf format.
2441 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
2443 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
2444 Only r_alloc_inhibit_buffer_relocation needed to be added;
2445 the others were already declared.
2447 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
2448 before checking whether it's out of range. Put the check inside
2449 eassert. See
2450 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
2452 2012-05-27 Ken Brown <kbrown@cornell.edu>
2454 * callproc.c (Fcall_process): Restore a line that was accidentally
2455 commented out in the 2011-02-13 change (bug#11547).
2457 2012-05-27 Eli Zaretskii <eliz@gnu.org>
2459 * lisp.h [REL_ALLOC]: Add prototypes for external functions
2460 defined on ralloc.c.
2462 * buffer.c [REL_ALLOC]: Remove prototypes of
2463 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
2464 they are now on lisp.h.
2466 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
2468 * search.c (search_buffer): Use it to inhibit relocation of buffer
2469 text while re_search_2 is doing its job, because re_search_2 is
2470 passed C pointers to buffer text. (Bug#11519)
2472 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
2473 Update value to 24.
2475 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
2476 state after an additional call to move_it_in_display_line_to, keep
2477 the values of it->max_ascent and it->max_descent found for the
2478 entire line.
2479 (pos_visible_p): Revert the comparison against bottom_y to what it
2480 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
2481 (Bug#11464)
2483 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
2485 Fix coding-related core dumps with gcc -ftrapv.
2486 The code was computing A - B, where A and B are pointers, and B is
2487 random garbage. This can lead to core dumps on platforms that
2488 have special pointer registers, and it also leads to core dumps on
2489 x86-64 when compiled with gcc -ftrapv. The fix is to compute
2490 A - B only when B is initialized properly.
2491 * coding.c (coding_set_source, coding_set_destination): Return void.
2492 (coding_change_source, coding_change_destinations): New functions,
2493 with the old behaviors of coding_set_source and coding_set_destination.
2494 All callers that need an offset changed to use these new functions.
2496 2012-05-26 Glenn Morris <rgm@gnu.org>
2498 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
2500 2012-05-26 Eli Zaretskii <eliz@gnu.org>
2502 Extend mouse support on W32 text-mode console.
2503 * xdisp.c (draw_row_with_mouse_face):
2504 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
2506 * w32console.c: Include window.h.
2507 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
2508 New functions.
2509 (initialize_w32_display): Initialize mouse-highlight data.
2511 * w32inevt.c: Include termchar.h and window.h.
2512 (do_mouse_event): Support mouse-autoselect-window. When the mouse
2513 moves, call note_mouse_highlight. If help_echo changed, call
2514 gen_help_event to produce help-echo message in the echo area.
2515 Call clear_mouse_face if mouse_face_hidden is set in the mouse
2516 highlight info.
2518 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
2520 * lread.c (read1): Simplify slightly to avoid an overflow warning
2521 with GCC 4.7.0 on x86-64.
2523 2012-05-26 Eli Zaretskii <eliz@gnu.org>
2525 * bidi.c (bidi_mirror_char): Revert last change: an int is
2526 definitely wide enough here.
2528 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
2530 Fix integer width and related bugs (Bug#9874).
2531 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
2532 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
2533 (string_bytes, check_sblock, allocate_string_data):
2534 (compact_small_strings, Fmake_bool_vector, make_string)
2535 (make_unibyte_string, make_multibyte_string)
2536 (make_string_from_bytes, make_specified_string)
2537 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
2538 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
2539 (mark_vectorlike):
2540 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2541 (allocate_pseudovector):
2542 Use int, not EMACS_INT, where int is wide enough.
2543 (inhibit_garbage_collection, Fgarbage_collect):
2544 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2545 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
2546 int might not be wide enough.
2547 (bidi_cache_search, bidi_cache_find, bidi_init_it)
2548 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2549 (bidi_at_paragraph_end, bidi_find_paragraph_start)
2550 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
2551 (bidi_level_of_next_char, bidi_move_to_visually_next):
2552 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2553 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
2554 (Fkill_buffer, Fset_buffer_major_mode)
2555 (advance_to_char_boundary, Fbuffer_swap_text)
2556 (Fset_buffer_multibyte, overlays_at, overlays_in)
2557 (overlay_touches_p, struct sortvec, record_overlay_string)
2558 (overlay_strings, recenter_overlay_lists)
2559 (adjust_overlays_for_insert, adjust_overlays_for_delete)
2560 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
2561 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
2562 (Foverlay_recenter, last_overlay_modification_hooks_used)
2563 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
2564 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2565 (validate_region): Omit unnecessary test for b <= e,
2566 since that's guaranteed by the previous test.
2567 (adjust_overlays_for_delete): Avoid pos + length overflow.
2568 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
2569 (report_overlay_modification):
2570 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2571 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
2572 Omit pointer cast, which isn't needed anyway, and doesn't work
2573 after the EMACS_INT -> ptrdiff_t change.
2574 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
2575 * buffer.h: Adjust decls to match defn changes elsewhere.
2576 (struct buffer_text, struct buffer):
2577 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2578 Use EMACS_INT, not int, where int might not be wide enough.
2579 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
2580 not int, to avoid needless 32-bit limit on 64-bit hosts.
2581 (exec_byte_code): Use tighter memory-full test, one that checks
2582 for alloca overflow. Don't compute the address of the object just
2583 before an array, as that's not portable. Use EMACS_INT, not
2584 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
2585 * callint.c (Fcall_interactively):
2586 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2587 * callproc.c (call_process_kill, Fcall_process):
2588 Don't assume pid_t fits into an Emacs fixnum.
2589 (call_process_cleanup, Fcall_process, child_setup):
2590 Don't assume pid_t fits into int.
2591 (call_process_cleanup, Fcall_process, delete_temp_file)
2592 (Fcall_process_region):
2593 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2594 (Fcall_process): Simplify handling of volatile integers.
2595 Use int, not EMACS_INT, where int will do.
2596 * casefiddle.c (casify_object, casify_region, operate_on_word)
2597 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
2598 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2599 (casify_object): Avoid integer overflow when overallocating buffer.
2600 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
2601 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
2602 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
2603 * category.h (CATEGORYP): Don't assume arg is nonnegative.
2604 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
2605 integers are now checked earlier. All uses replaced with XINT.
2606 (ccl_driver):
2607 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2608 For CCL_MapSingle, check that content and value are in int range.
2609 (ccl_driver, Fregister_code_conversion_map):
2610 Check that Vcode_version_map_vector is a vector.
2611 (resolve_symbol_ccl_program): Check that vector header is in range.
2612 Always copy the vector, so that we can check its contents reliably
2613 now rather than having to recheck each instruction as it's being
2614 executed. Check that vector words fit in 'int'.
2615 (ccl_get_compiled_code, Fregister_ccl_program)
2616 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
2617 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
2618 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
2619 contents are in range.
2620 (Fccl_execute_on_string): Check that status is in range.
2621 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
2622 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
2623 Accept and return EMACS_INT, not int, because callers can pass values
2624 out of 'int' range.
2625 (c_string_width, strwidth, lisp_string_width, chars_in_text)
2626 (multibyte_chars_in_text, parse_str_as_multibyte)

2628 (str_as_unibyte, str_to_unibyte, string_count_byte8)
2629 (string_escape_byte8, Fget_byte):
2630 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2631 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
2632 avoid mishandling large integers.
2633 * character.h: Adjust decls to match defn changes elsewhere.
2634 * charset.c (load_charset_map_from_file, find_charsets_in_text)
2635 (Ffind_charset_region):
2636 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2637 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
2638 (load_charset_map_from_vector, Fdefine_charset_internal):
2639 Don't assume fixnum fits in int.
2640 (load_charset_map_from_vector, Fmap_charset_chars):
2641 Remove now-unnecessary CHECK_NATNUMs.
2642 (Fdefine_charset_internal): Check ranges here, more carefully.
2643 Don't rely on undefined behavior with signed left shift overflow.
2644 Don't assume unsigned int fits into fixnum, or that fixnum fits
2645 into unsigned int. Don't require max_code to be a valid fixnum;
2646 that's not true for gb10830 4-byte on a 32-bit host. Allow
2647 invalid_code to be a cons, for the same reason. Require code_offset
2648 to be a character. Avoid int overflow if max_char is close
2649 to INT_MAX.
2650 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
2651 this is intended anyway and avoids some undefined behavior.
2652 (load_charset_map): Pass unsigned, not int, as 2nd arg of
2653 INDEX_TO_CODE_POINT, as that's what it expects.
2654 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
2655 * charset.h (DECODE_CHAR): Return int, not unsigned;
2656 this is what was intended anyway, and it avoids undefined behavior.
2657 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
2658 integer-overflow issues.
2659 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
2660 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
2661 where the argument is EMACS_INT, and this behavior is not intended.
2662 * chartab.c (Fmake_char_table, Fset_char_table_range)
2663 (uniprop_get_decoder, uniprop_get_encoder):
2664 Don't assume fixnum fits in int.
2665 * cmds.c (move_point): New function, that does the gist of
2666 Fforward_char and Fbackward_char, but does so while checking
2667 for integer overflow more accurately.
2668 (Fforward_char, Fbackward_char): Use it.
2669 (Fforward_line, Fend_of_line, internal_self_insert)
2670 (internal_self_insert):
2671 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2672 Fix a FIXME, by checking for integer overflow when calculating
2673 target_clm and actual_clm.
2674 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)

2703 (Funencodable_char_position, Fcheck_coding_systems_region)
2704 (get_translation, handle_composition_annotation, consume_chars):
2705 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2706 (consume_chars): Rewrite to not calculate an address outside buffer.
2707 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
2708 Don't access memory outside of the args array.
2709 (Fdefine_coding_system_internal): Check for charset-id overflow.
2710 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
2711 result of ENCODE_CHAR.
2712 * coding.h: Adjust decls to match defn changes elsewhere.
2713 (struct coding_system):
2714 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

3415 * xgselect.c: Include xterm.h.
3416 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
3417 and `display_arg' (bug#9754).
3419 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
3421 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
3423 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
3424 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
3426 2012-05-18 Eli Zaretskii <eliz@gnu.org>
3428 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
3430 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
3431 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
3433 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
3434 reference to image_cache->refcount.
3435 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
3437 2012-05-17 Juri Linkov <juri@jurta.org>
3439 * search.c (Fword_search_regexp, Fword_search_backward)
3440 (Fword_search_forward, Fword_search_backward_lax)
3441 (Fword_search_forward_lax): Move functions to isearch.el
3442 (bug#10145, bug#11381).
3444 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
3446 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
3448 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
3450 * lread.c (init_obarray): Declare Qt and Qnil as special.
3452 2012-05-14 Glenn Morris <rgm@gnu.org>
3454 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
3455 Put "libexec" before "bin", for the sake of init_callproc_1.
3457 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3459 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
3461 * unexaix.c: Port to more-recent AIX compilers.
3462 (report_error, report_error_1, make_hdr, copy_sym)
3463 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
3464 Make arguments const char *, not char *, to avoid violations of C
3465 standard and to fix some AIX warnings reported by Gilles Pion.
3467 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3469 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
3470 already have overlays loaded.
3471 (handle_single_display_spec): Before returning without displaying
3472 fringe bitmap, synchronize the bidi iterator with the main display
3473 iterator, by calling iterate_out_of_display_property.
3474 (iterate_out_of_display_property): Detect buffer iteration by
3475 testing that it->string is a Lisp string.
3476 (get_next_display_element): When the current object is exhausted,
3477 and there's something on it->stack, call set_iterator_to_next to
3478 proceed with what's on the stack, instead of returning zero.
3479 (set_iterator_to_next): If called at the end of a Lisp string,
3480 proceed to consider_string_end without incrementing string
3481 position. Don't increment display vector index past the end of
3482 the display vector. (Bug#11417)
3483 (pos_visible_p): Don't report a position visible when move_it_to
3484 stopped at the last line of window, which happens to be scanned
3485 backwards by the bidi iteration. (Bug#11464)
3487 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3489 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
3490 and right-margin display specs even if the spec is invalid or we
3491 are on a TTY, and thus unable to display on the fringes.
3492 That's because the text with the property will not be displayed anyway,
3493 so we need to signal to the caller that this is a "replacing"
3494 display spec. This fixes display when the spec is invalid or we
3495 are on a TTY.
3497 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3499 * unexaix.c (make_hdr): Fix typo in prototype.
3500 This bug broke the build on AIX. Problem reported by Gilles Pion.
3502 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
3504 * keyboard.c (kbd_buffer_get_event): Read special events also in
3505 batch mode. (Bug#11415)
3507 2012-05-12 Glenn Morris <rgm@gnu.org>
3509 * ns.mk: Update for ns_appbindir no longer having trailing "/".
3511 2012-05-12 Eli Zaretskii <eliz@gnu.org>
3513 * lisp.mk (lisp): Add newcomment.elc.
3515 2012-05-12 Glenn Morris <rgm@gnu.org>
3517 * Makefile.in (MKDIR_P): New, set by configure.
3518 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
3520 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
3522 Remove unused function hourglass_started.
3523 * dispextern.h (hourglass_started):
3524 * w32fns.c (hourglass_started):
3525 * xdisp.c (hourglass_started): Remove.
3527 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
3529 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
3530 Update dependencies.
3532 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
3534 * xgselect.c (xg_select): Put maxfds+1 into a var.
3535 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
3537 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
3539 2012-05-10 Dave Abrahams <dave@boostpro.com>
3541 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
3542 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
3544 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
3546 * dbusbind.c (xd_registered_buses): New internal Lisp object.
3547 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
3548 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
3549 Initialize xd_registered_buses.
3551 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
3553 Untag more efficiently if USE_LSB_TAG.
3554 This is based on a proposal by YAMAMOTO Mitsuharu in
3555 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
3556 For an admittedly artificial (nth 8000 longlist) benchmark on
3557 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
3558 Emacs's overall text size by 1%.
3559 * lisp.h (XUNTAG): New macro.
3560 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
3561 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
3562 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
3563 * eval.c (Fautoload):
3564 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
3565 * frame.h (XFRAME): Use XUNTAG.
3567 Port recent dbusbind.c changes to 32-bit --with-wide-int.
3568 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
3569 Remove unportable assumptions about print widths of types like
3570 dbus_uint32_t.
3571 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
3572 intptr_t when converting between pointer and integer, to avoid GCC
3573 warnings about wrong width.
3575 2012-05-09 Eli Zaretskii <eliz@gnu.org>
3577 * w32proc.c (new_child): Force Windows to reserve only 64KB of
3578 stack for each reader_thread, instead of defaulting to 8MB
3579 determined by the linker. This avoids failures in creating
3580 subprocesses on Windows 7, see the discussion in this thread:
3581 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
3583 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
3585 Fix up display of the *Minibuf-0* buffer in the mini window.
3586 * keyboard.c (read_char): Don't clear the echo area if there's no
3587 message to clear.
3588 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
3589 contents of *Minibuf-0*) if there's no message displayed in its stead.
3591 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
3593 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
3594 batch mode.
3596 2012-05-06 Chong Yidong <cyd@gnu.org>
3598 * lisp.mk (lisp): Update.
3600 2012-05-05 Jim Meyering <meyering@redhat.com>
3602 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
3604 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
3606 * data.c (PUT_ERROR): New macro.
3607 (syms_of_data): Use it. Add new error type `user-error'.
3608 * undo.c (user_error): New function.
3609 (Fprimitive_undo): Use it.
3610 * print.c (print_error_message): Adjust print style for `user-error'.
3611 * keyboard.c (user_error): New function.
3612 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
3614 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
3616 Do not limit current-time-string to years 1000..9999.
3617 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
3618 (Fcurrent_time_string): Support any year that is supported by the
3619 underlying localtime representation. Don't use asctime, as it
3620 has undefined behavior for years outside the range -999..9999.
3622 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
3624 Fix race conditions involving setenv, gmtime, localtime, asctime.
3625 Without this fix, interrupts could mess up code that uses these
3626 nonreentrant functions, since setting TZ invalidates existing
3627 tm_zone or tzname values, and since most of these functions return
3628 pointers to static storage.
3629 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
3630 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
3631 Grow the critical sections to include not just invoking
3632 localtime/gmtime, but also accessing these functions' results
3633 including their tm_zone values if any, and any related TZ setting.
3634 (format_time_string): Last arg is now struct tm *, not struct tm **,
3635 so that the struct tm is saved in the critical section.
3636 All callers changed. Simplify allocation of initial buffer, partly
3637 motivated by the fact that memory allocation needs to be outside
3638 the critical section.
3640 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
3642 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
3643 with RESET_INTERVAL.
3645 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
3646 Remove duplicated buffer name initialization.
3648 2012-05-02 Jim Meyering <jim@meyering.net>
3650 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
3652 * xfns.c (x_window): Use xstrdup (Bug#11375).
3654 2012-05-02 Eli Zaretskii <eliz@gnu.org>
3656 * xdisp.c (pos_visible_p): If already at a newline from the
3657 display string before the 'while' loop, don't walk back the glyphs
3658 from it3.glyph_row. Solves assertion violation when the display
3659 string begins with a newline (egg.el). (Bug#11367)
3661 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
3663 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
3664 Move to simple.el.
3666 2012-05-01 Glenn Morris <rgm@gnu.org>
3668 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
3669 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
3670 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
3671 All were removed before 23.1.
3673 * dispnew.c: Remove HAVE_LIBNCURSES test;
3674 it is always true on relevant platforms.
3676 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
3677 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
3679 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
3681 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
3683 * .gdbinit (xpr): Remove checks for no longer existing misc types.
3684 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
3685 Remove.
3687 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
3689 Do not avoid creating empty evaporating overlays (Bug#9642).
3690 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
3691 That is, do not delete an evaporating overlay if it becomes
3692 empty after its bounds are adjusted to fit within its buffer.
3693 This fix caused other problems, and I'm reverting it until we get
3694 to the bottom of them.
3696 2012-04-27 Chong Yidong <cyd@gnu.org>
3698 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
3700 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3702 * xdisp.c (pos_visible_p): If the window start position is beyond
3703 ZV, start the display from buffer beginning. Prevents assertion
3704 violation in init_iterator when the minibuffer window is scrolled
3705 via the scroll bar.
3707 * window.c (window_scroll_pixel_based): Likewise.
3709 2012-04-27 Chong Yidong <cyd@gnu.org>
3711 * keymap.c (where_is_internal): Doc fix (Bug#10872).
3713 2012-04-27 Glenn Morris <rgm@gnu.org>
3715 * fileio.c (Fcopy_file, Fset_file_selinux_context):
3716 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
3718 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3720 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
3721 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
3723 2012-04-26 Eli Zaretskii <eliz@gnu.org>
3725 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
3726 display element, check also the underlying string or buffer
3727 character. (Bug#11341)
3729 * w32menu.c: Include w32heap.h.
3730 (add_menu_item): If the call to AppendMenuW (via
3731 unicode_append_menu) fails, disable Unicode menus only if we are
3732 running on Windows 9X/Me.
3734 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
3736 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
3737 (xgetint): Add missing shift for LSB tags.
3739 2012-04-24 Martin Rudalics <rudalics@gmx.at>
3741 * keyboard.c (read_char): Don't wipe echo area for select window
3742 events: These might get delayed via `mouse-autoselect-window'
3743 (Bug#11304).
3745 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
3747 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
3748 manipulation of :loaded-from data.
3750 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
3752 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
3753 now a cons (bug#11311).
3755 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
3757 Do not create empty overlays with the evaporate property (Bug#9642).
3758 * buffer.c (Fmove_overlay): Delete an evaporating overlay
3759 if it becomes empty after its bounds are adjusted to fit within
3760 its buffer. Without this fix, in a nonempty buffer (let ((o
3761 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
3762 yields an empty overlay that has the evaporate property, which is
3763 not supposed to happen.
3765 Fix minor GTK3 problems found by static checking.
3766 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
3767 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
3768 (struct _EmacsFixedClass, emacs_fixed_get_type):
3769 Move decls here from emacsgtkfixed.h, since they needn't be public.
3770 (emacs_fixed_get_type): Now static.
3771 (emacs_fixed_class_init): Omit unused local.
3772 (emacs_fixed_child_type): Remove; unused.
3773 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
3774 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
3775 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
3776 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
3777 (EMACS_FIXED_GET_CLASS): Remove; unused.
3778 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
3780 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
3781 Problem reported by Juanma Barranquero for Windows -Wunused-function.
3783 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
3785 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
3786 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
3787 (__malloc_size_t, __malloc_ptrdiff_t):
3788 Remove. All uses removed, replaced by the definiens if needed,
3789 since we can assume C89 or better now.
3790 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
3791 (protect_malloc_state, align, get_contiguous_space)
3792 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
3793 (malloc_atfork_handler_child, malloc_enable_thread)
3794 (malloc_initialize_1, __malloc_initialize, morecore_nolock)
3795 (_malloc_internal_nolock, _malloc_internal, malloc, _malloc)
3796 (_free, _realloc, _free_internal_nolock, _free_internal, free, cfree)
3797 (special_realloc, _realloc_internal_nolock, _realloc_internal)
3798 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
3799 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
3800 Define using prototypes, not old style.
3801 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
3802 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
3803 (align): Don't assume that signed integer overflow wraps around.
3804 Omit unused local var.
3805 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
3806 (_free_internal_nolock, memalign, mallochook, reallochook):
3807 Omit no-longer-needed casts.
3808 (valloc): Use getpagesize, not __getpagesize.
3809 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
3810 (struct hdr): The 'magic' member is now size_t, not unsigned long.
3812 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
3814 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
3816 Move functions from C to Lisp. Make non-blocking method calls
3817 the default. Implement further D-Bus standard interfaces.
3819 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
3820 (QCdbus_request_name_allow_replacement)
3821 (QCdbus_request_name_replace_existing)
3822 (QCdbus_request_name_do_not_queue)
3823 (QCdbus_request_name_reply_primary_owner)
3824 (QCdbus_request_name_reply_in_queue)
3825 (QCdbus_request_name_reply_exists)
3826 (QCdbus_request_name_reply_already_owner): Move to dbus.el.
3827 (QCdbus_registered_serial, QCdbus_registered_method)
3828 (QCdbus_registered_signal): New Lisp objects.
3829 (XD_DEBUG_MESSAGE): Use sizeof.
3830 (XD_MESSAGE_TYPE_TO_STRING, XD_OBJECT_TO_STRING)
3831 (XD_DBUS_VALIDATE_BUS_ADDRESS, XD_DBUS_VALIDATE_OBJECT)
3832 (XD_DBUS_VALIDATE_BUS_NAME, XD_DBUS_VALIDATE_PATH)

3838 Return cached address.
3839 (xd_remove_watch): Do not unset $DBUS_SESSION_BUS_ADDRESS.
3840 (xd_close_bus): Rename from Fdbus_close_bus. Not needed on Lisp
3841 level.
3842 (Fdbus_init_bus): New optional arg PRIVATE. Cache address.
3843 Return number of refcounts.
3844 (Fdbus_get_unique_name): Make stronger parameter check.

3846 (Fdbus_call_method, Fdbus_call_method_asynchronously)
3847 (Fdbus_method_return_internal, Fdbus_method_error_internal)
3848 (Fdbus_send_signal, Fdbus_register_service)
3849 (Fdbus_register_signal, Fdbus_register_method): Move to dbus.el.
3850 (xd_read_message_1): Obey new structure of Vdbus_registered_objects.
3851 (xd_read_queued_messages): Obey new structure of Vdbus_registered_buses.
3852 (Vdbus_compiled_version, Vdbus_runtime_version)
3853 (Vdbus_message_type_invalid, Vdbus_message_type_method_call)
3854 (Vdbus_message_type_method_return, Vdbus_message_type_error)
3855 (Vdbus_message_type_signal): New defvars.

3865 * alloc.c: Handle unusual debugging option combinations.
3866 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
3867 since the two debugging options are incompatible.
3868 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
3869 is defined.
3870 (mem_init, mem_insert, mem_insert_fixup):
3871 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
3872 (NEED_MEM_INSERT): Remove; no longer needed.
3874 2012-04-22 Leo Liu <sdl.web@gmail.com>
3876 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
3878 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
3880 * sysdep.c [__FreeBSD__]: Minor cleanups.
3881 (list_system_processes, system_process_attributes) [__FreeBSD__]:
3882 Use Emacs indenting style more consistently. Avoid some casts.

3885 2012-04-21 Eduard Wiebe <usenet@pusto.de>
3887 * sysdep.c (list_system_processes, system_process_attributes):
3888 Add implementation for FreeBSD (Bug#5243).
3890 2012-04-21 Andreas Schwab <schwab@linux-m68k.org>
3892 * lisp.mk (lisp): Update.
3894 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
3896 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
3897 It is never used otherwise.

3901 * print.c (print_preprocess): Only check print_depth if print-circle
3902 is nil.
3903 (print_object): Check for cycles even when print-circle is nil and
3904 print-gensym is t, but only check print_depth if print-circle is nil.
3906 2012-04-20 Chong Yidong <cyd@gnu.org>
3908 * process.c (wait_reading_process_output): If EIO occurs on a pty,
3909 set the status to "failed" and ensure that sentinel is run.
3911 2012-04-20 Glenn Morris <rgm@gnu.org>
3913 * process.c (Fset_process_inherit_coding_system_flag)
3914 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

3920 BEGV.
3921 (set_cursor_from_row): If called for a mode-line or header-line
3922 row, return zero immediately.
3923 (try_cursor_movement): If inside continuation line, don't back up
3924 farther than the first row after the header line, if any.
3925 Don't consider the header-line row as "partially visible", even if
3926 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
3928 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
3930 * lread.c (lisp_file_lexically_bound_p): Fix hang at ";-*-\n"
3931 (bug#11238).
3933 2012-04-20 Teodor Zlatanov <tzz@lifelogs.com>
3934 2012-04-18 Paul Eggert <eggert@cs.ucla.edu>
3936 configure: new option --enable-gcc-warnings (Bug#11207)
3937 * Makefile.in (C_WARNINGS_SWITCH): Remove.
3938 (WARN_CFLAGS, WERROR_CFLAGS): New macros.
3939 (ALL_CFLAGS): Use new macros rather than old.
3940 * process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.
3941 * regex.c: Ignore -Wstrict-overflow. If !emacs, also ignore
3942 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
3943 -Wunused-result, -Wunused-variable. This should go away once
3944 the Emacs and Gnulib regex code is merged.
3945 (xmalloc, xrealloc): Now static.
3947 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>
3949 * dired.c (Fsystem_groups): Remove unused local.
3951 2012-04-17 Glenn Morris <rgm@gnu.org>

3962 Fix minor alloc.c problems found by static checking.
3963 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
3964 New extern decls, to avoid calling undeclared functions.
3965 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
3966 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
3967 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
3968 (NEED_MEM_INSERT): New macro.
3969 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
3970 Remove one incorrect comment and fix another.

3976 (r_alloc_sbrk): Now static.
3978 Improve ralloc.c interface checking.
3979 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html

3983 [REL_ALLOC]: ... to here, to check interface.
3984 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
3985 Remove decls. This fixes an "It stinks!".
3987 * alloc.c (which_symbols): Fix alignment issue / type clash.
3989 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
3991 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
3992 (struct Lisp_Misc_Any): Likewise.

4002 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
4004 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
4005 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
4006 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
4007 * s/netbsd.h, s/sol2-6.h:
4008 Remove definition of GC_MARK_STACK, since the default now works.
4009 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
4010 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
4011 no longer the default.
4012 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
4014 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
4016 * lread.c (lisp_file_lexically_bound_p):
4017 Fix hang at ";-*-\n" (bug#11238).
4019 2012-04-14 Eli Zaretskii <eliz@gnu.org>
4021 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row

4026 * nsterm.m (constrainFrameRect): Always constrain when there is only
4027 one screen (Bug#10962).
4029 2012-04-13 Ken Brown <kbrown@cornell.edu>
4031 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
4033 2012-04-13 Reuben Thomas <rrt@sc3d.org>
4035 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
4037 2012-04-11 Daniel Colascione <dancol@dancol.org>
4039 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
4040 against is gone. It's better to use vfork now so that when Cygwin
4041 gains a new, working vfork, we use it automatically (bug#10398).
4043 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
4045 * window.c (save_window_save): Obey window-point-insertion-type.
4047 2012-04-11 Glenn Morris <rgm@gnu.org>

4058 (force_quit_count): New var.
4059 (handle_interrupt): Use it.
4061 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
4063 * w32.c (w32_delayed_load): Record the full path of the library
4064 being loaded (bug#10424).
4066 2012-04-09 Glenn Morris <rgm@gnu.org>
4068 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
4069 not just in the obarray, before snarfing them. (Bug#11036)
4071 * Makefile.in ($(leimdir)/leim-list.el):
4072 Pass EMACS rather than BUILT_EMACS.
4074 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
4076 * process.c (make_process):
4077 * process.h: Add integer `gnutls_handshakes_tried' member to
4078 process struct.
4080 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
4081 Add convenience `GNUTLS_LOG2i' macro.
4083 * gnutls.c (gnutls_log_function2i): Convenience log function.
4084 (emacs_gnutls_read): Use new log functions,
4085 `gnutls_handshakes_tried' process member, and
4086 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
4087 attempts per process (connection).
4089 2012-04-09 Chong Yidong <cyd@gnu.org>
4091 * eval.c (Fuser_variable_p, user_variable_p_eh)
4092 (lisp_indirect_variable): Functions deleted.

4096 * minibuf.c (Fread_variable): Callers changed.
4098 2012-04-09 Eli Zaretskii <eliz@gnu.org>
4100 * xdisp.c (set_cursor_from_row): If the display string appears in
4101 the buffer at position that is closer to point than the position
4102 after the display string, display the cursor on the first glyph of
4103 the display string. Fixes cursor display when a 'display' text
4104 property immediately follows invisible text. (Bug#11094)
4106 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
4108 composite.c: use 'double' consistently
4109 * composite.c (get_composition_id): Use 'double' consistently
4110 instead of converting 'float' to 'double' and vice versa; this is
4111 easier to understand and avoids a GCC warning.
4113 2012-04-09 Glenn Morris <rgm@gnu.org>
4115 * Makefile.in: Generate leim-list with bootstrap-emacs, in
4116 preparation for dumping it with emacs. (Bug#4789)
4117 (leimdir): New variable.

4138 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
4139 (mark_memory): Mark Lisp_Objects only if pointers might hide in
4140 objects, as mark_maybe_pointer will catch them otherwise.
4141 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
4142 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

4153 * makefile.w32-in (OBJ2): Add xml.$(O).
4154 (GLOBAL_SOURCES): Add xml.c.
4155 ($(BLD)/xml.$(O)): New dependency list.
4157 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
4158 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
4159 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
4160 [!WINDOWSNT]: New macros.
4161 (init_libxml2_functions, libxml2_loaded_p): New functions.
4162 (parse_region): Call fn_xmlCheckVersion instead of using the macro
4163 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
4164 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
4165 Calls xmlCleanupParser only if libxml2 was loaded (or statically
4166 linked in).
4167 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
4168 Call init_libxml2_functions before calling libxml2 functions.
4169 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
4171 * emacs.c: Don't include libxml/parser.h.
4172 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
4173 xmlCleanupParser directly.
4175 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
4177 2012-04-07 Eli Zaretskii <eliz@gnu.org>
4179 * indent.c (Fvertical_motion): If there is a display string at
4180 point, use it.vpos to compute how many lines to backtrack after
4181 move_it_to point. (Bug#11133)
4183 2012-04-06 Eli Zaretskii <eliz@gnu.org>
4185 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
4186 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
4187 about subtle differences between FETCH_CHAR* and STRING_CHAR*
4188 macros related to unification of CJK characters. For the details,
4189 see the discussion following the message here:
4190 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
4192 2012-04-04 Chong Yidong <cyd@gnu.org>
4194 * keyboard.c (Vdelayed_warnings_list): Doc fix.
4196 2012-04-01 Eli Zaretskii <eliz@gnu.org>
4198 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
4199 instead of alloca. (Bug#11138)
4201 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
4203 * w32menu.c (is_simple_dialog): Properly check lisp types.

4206 2012-03-31 Eli Zaretskii <eliz@gnu.org>
4208 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
4209 position we get to after a call to move_it_to fails the
4210 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
4211 only if we wind up in a string from display property. (Bug#11063)
4213 * window.c (Fdelete_other_windows_internal): Invalidate the row
4214 and column information about mouse highlight, so that redisplay
4215 restores it after reallocating the glyph matrices. (Bug#7464)
4217 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
4218 string comes from a `display' text property, use the buffer
4219 position of that property as if we actually saw that position in
4220 the row's glyphs.
4221 (move_it_by_lines): Remove the assertion that
4222 "it->current_x == 0 && it->hpos == 0" which can be legitimately
4223 violated when there's a before-string at the beginning of a line.
4224 (Bug#11063)
4226 2012-03-30 Eli Zaretskii <eliz@gnu.org>
4228 * xdisp.c (append_space_for_newline): If the default face was
4229 remapped, use the remapped face for the appended newline.
4230 (extend_face_to_end_of_line): Use the remapped default face for
4231 extending the face to the end of the line.
4232 (display_line): Call extend_face_to_end_of_line when the default
4233 face was remapped. (Bug#11068)
4235 2012-03-29 Eli Zaretskii <eliz@gnu.org>
4237 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
4239 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
4241 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
4243 2012-03-27 Glenn Morris <rgm@gnu.org>
4245 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
4246 Doc fixes.
4248 2012-03-26 Kenichi Handa <handa@m17n.org>

4255 * keyboard.c (Vselection_inhibit_update_commands): New variable.
4256 (command_loop_1): Use it; inhibit selection update for
4257 handle-select-window too (Bug#8996).
4259 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
4261 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
4263 2012-03-25 Kenichi Handa <handa@m17n.org>
4265 * dispextern.h (struct glyph): Change the bit length of
4266 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
4268 2012-03-24 Eli Zaretskii <eliz@gnu.org>
4270 * s/ms-w32.h (tzname): Include time.h before redirecting to
4271 _tzname. Fixes the MSVC build. (Bug#9960)
4273 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
4275 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
4276 characters.
4278 * xterm.c (XTread_socket): Only modify handling_signal if
4279 !SYNC_INPUT. (Bug#11080)
4281 2012-03-23 Eli Zaretskii <eliz@gnu.org>
4283 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
4284 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
4285 when fetching a multibyte character consumes more bytes than
4286 CHAR_BYTES returns, due to unification of CJK characters in
4287 string_char. (Bug#11073)
4289 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
4291 * process.c (wait_reading_process_output): Handle pty disconnect
4292 by refraining from sending oneself a SIGCHLD (bug#10933).
4294 2012-03-22 Chong Yidong <cyd@gnu.org>
4296 * dispextern.h (struct it): New member string_from_prefix_prop_p.
4298 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
4299 Mark string as coming from a prefix property.
4300 (handle_face_prop): Use default face for prefix strings (Bug#4281).
4301 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
4303 2012-03-21 Chong Yidong <cyd@gnu.org>
4305 * xfaces.c (Vface_remapping_alist): Doc fix.
4307 2012-03-20 Eli Zaretskii <eliz@gnu.org>
4309 * w32proc.c (Fw32_set_console_codepage)
4310 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
4311 Doc fixes.

4321 it fit in a valid range (Bug#11003).
4323 2012-03-18 Eli Zaretskii <eliz@gnu.org>
4325 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
4326 that is not from display property, accept the row as a "cursor
4327 row" if one of the string's character has a non-nil `cursor'
4328 property. Fixes cursor positioning when there are newlines in
4329 overlay strings, e.g. in icomplete.el. (Bug#11035)
4331 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

4359 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
4361 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
4362 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
4363 zero (Bug#10954).
4365 2012-03-03 Glenn Morris <rgm@gnu.org>
4367 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.

4378 2012-03-02 Glenn Morris <rgm@gnu.org>
4380 * buffer.c (buffer-list-update-hook): Doc fix.
4382 2012-02-29 Eli Zaretskii <eliz@gnu.org>

4385 push_it before setting up the iterator for the first overlay
4386 string, even if we have an empty string loaded.
4387 (next_overlay_string): If there's an empty string on the iterator
4388 stack, pop the stack. (Bug#10903)
4390 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
4392 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
4393 Suggested by Stefan Monnier in
4394 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
4395 * alloc.c (widen_to_Lisp_Object): New static function.
4396 (mark_memory): Also mark Lisp_Objects by fetching pointer words
4397 and widening them to Lisp_Objects. This would work even if
4398 USE_LSB_TAG is defined and wide integers are used, which might
4399 happen in a future version of Emacs.
4401 2012-02-25 Chong Yidong <cyd@gnu.org>
4403 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

4422 (run_window_configuration_change_hook): Obey it.
4423 (syms_of_window): Initialize it.
4425 2012-02-22 Chong Yidong <cyd@gnu.org>
4427 * xterm.c (x_draw_image_relief): Add missing type check for

4440 when computing $valmask.
4442 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
4443 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
4444 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
4445 It's useless in that case, and it can cause problems on hosts
4446 that allocate halves of EMACS_INT values separately.
4447 Reported by Dan Horák. Diagnosed by Andreas Schwab in
4448 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
4449 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
4450 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
4451 it avoids undefined behavior on hosts where shifting right by more
4452 than the word width has undefined behavior.
4454 2012-02-19 Chong Yidong <cyd@gnu.org>
4456 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
4457 (Funhandled_file_name_directory, Ffile_name_as_directory)
4458 (Fdirectory_file_name, Fexpand_file_name)
4459 (Fsubstitute_in_file_name): Protect against invalid file handler
4460 return values (Bug#10845).

4474 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
4476 2012-02-15 Chong Yidong <cyd@gnu.org>
4478 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

4494 2012-02-12 Chong Yidong <cyd@gnu.org>
4496 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
4497 as that creates a dangerous corner case.
4499 * window.c (Fdelete_window_internal): Invalidate the mouse
4500 highlight (Bug#9904).
4502 2012-02-12 Glenn Morris <rgm@gnu.org>

4506 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
4507 * nsselect.m (Fx_own_selection_internal)
4508 (Fx_disown_selection_internal, Fx_selection_exists_p)
4509 (Fx_selection_owner_p, Fx_get_selection_internal):
4510 Sync docs and argument specs with the xselect.c versions.

4532 2012-02-07 Chong Yidong <cyd@gnu.org>
4534 * buffer.c (Fbuffer_local_variables)
4535 (buffer_lisp_local_variables): Handle unbound vars correctly;
4536 don't let Qunbound leak into Lisp.
4538 2012-02-07 Glenn Morris <rgm@gnu.org>
4540 * image.c (Fimagemagick_types): Doc fix.
4542 * image.c (imagemagick-render-type): Change it from a lisp object

4567 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
4568 after rounding frame sizes. (Bug#9723)
4570 2012-02-04 Eli Zaretskii <eliz@gnu.org>

4573 before BEGV. (Bug#10696)
4575 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
4577 Handle overflow when computing char display width (Bug#9496).
4578 * character.c (char_width): Return EMACS_INT, not int.
4579 (char_width, c_string_width): Check for overflow when
4580 computing the width; this is possible now that individual
4581 characters can have unbounded width. Problem introduced
4582 by merge from Emacs 23 on 2012-01-19.
4584 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

4613 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
4614 first 2 arguments are identical. This makes inserting large
4615 output from a subprocess an order of magnitude faster on
4616 MS-Windows, where all sbrk'ed memory is always contiguous.
4618 2012-01-31 Glenn Morris <rgm@gnu.org>

4717 string as eligible for mouse highlight. Fixes mouse highlight of
4718 display strings from overlays. (Bug#10464)
4720 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
4722 emacs: fix an auto-save permissions race condition (Bug#10400)
4723 * fileio.c (auto_saving_dir_umask): New static var.
4724 (Fmake_directory_internal): Use it.
4725 (do_auto_save_make_dir): Set it, instead of invoking chmod after

5116 * lisp.h (GCTYPEBITS): Move before first use.
5117 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
5118 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in

5232 Otherwise, valgrind does not work on some platforms.
5233 Problem reported by Andreas Schwab in
5234 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
5235 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
5236 is set, removing the need for VIRT_ADDRESS_VARIES.
5237 (PURE_P): Use a more-efficient implementation that needs just one
5238 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
5239 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
5240 to 4 (xorl, subq, cmpq, setbe).
5241 * alloc.c (pure): Always extern now, since that's the
5242 VIRT_ADDR_VARIES behavior.
5243 (PURE_POINTER_P): Use a single comparison, not two, for
5244 consistency with the new puresize.h.
5245 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
5246 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

5252 (erase_phys_cursor, update_window_cursor, show_mouse_face)
5253 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
5254 behave as if the cursor position were at the window margin.
5256 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
5257 and the cursor position is out of bounds, behave as if the cursor
5258 position were at the window margin. (Bug#10075)
5260 2011-11-18 Chong Yidong <cyd@gnu.org>
5262 * window.c (Fwindow_combination_limit): Make first argument
5263 non-optional, since it is meaningless for live windows like the
5264 selected window.
5266 2011-11-18 Dmitry Antipov <dmantipov@yandex.ru>
5268 * keymap.c (Fwhere_is_internal): Add missing RETURN_UNGCPROs.

5278 hash values of the two rows.
5279 (copy_row_except_pointers): Preserve the used[] arrays and the
5280 hash values of the two rows. (Bug#10035)
5281 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
5283 * xdisp.c (row_hash): New function, body extracted from
5284 compute_line_metrics.
5285 (compute_line_metrics): Call row_hash, instead of computing the
5286 hash code inline.
5288 * dispnew.c (verify_row_hash): Call row_hash for computing the
5289 hash code of a row, instead of duplicating code from xdisp.c.
5291 * dispextern.h (row_hash): Add prototype.
5293 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

5755 * process.c (make_process): Initialize GnuTLS credentials to NULL.
5756 (deactivate_process): Call emacs_gnutls_deinit.
5758 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
5760 * image.c (x_create_x_image_and_pixmap):
5761 * w32.c (sys_rename, w32_delayed_load):
5762 * w32font.c (fill_in_logfont):
5763 * w32reg.c (x_get_string_resource): Silence compiler warnings.
5765 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
5767 * w32fns.c (w32_default_color_map): New function,
5768 extracted from Fw32_default_color_map.
5769 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
5771 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
5773 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
5775 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
5777 * keyboard.c (test_undefined): New function (bug#9751).
5778 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
5780 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
5782 * sysdep.c (init_sys_modes): Fix the check for the controlling
5783 terminal (Bug#6649).
5785 2011-10-20 Eli Zaretskii <eliz@gnu.org>
5787 * dispextern.h (struct bidi_it): New member next_en_type.
5789 * bidi.c (bidi_line_init): Initialize the next_en_type member.
5790 (bidi_resolve_explicit_1): When next_en_pos is valid for the
5791 current character, check also for next_en_type being WEAK_EN.
5792 (bidi_resolve_weak): Don't enter the expensive loop if the current
5793 position is before next_en_pos. Record the bidi type of the first
5794 non-ET, non-BN character we find, in addition to its position.
5795 (bidi_level_of_next_char): Invalidate next_en_type when
5796 next_en_pos is over-stepped.
5798 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
5800 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
5801 * editfns.c: Rewrite current-time-zone so that it invokes
5802 the equivalent of (format-time-string "%Z") to get the time zone name.
5803 This fixes a bug when the time zone name contains characters that
5804 need converting from the system time locale to Emacs internal format.
5805 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
5806 that patch fixed format-time-string to do the conversion, but
5807 I forgot to fix current-time-zone.
5808 (format_time_string): New function, containing most of
5809 what Fformat_time_string used to contain.
5810 (Fformat_time_string): Rewrite in terms of format_time_string.
5811 This doesn't change this function's behavior.
5812 (current-time-zone): Rewrite to use format_time_string.
5813 This fixes the bug reported by Michael Schierl in
5814 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
5815 Jason Rumney's 2007-06-07 change worked around this bug, but
5816 didn't fix it.
5817 * systime.h (tzname, timezone): Remove no-longer-used declarations.
5819 2011-10-19 Eli Zaretskii <eliz@gnu.org>
5821 * xdisp.c (start_display): If the character at POS is displayed
5822 via a display vector, reset IT->current.dpvec_index to zero.
5823 (try_window_reusing_current_matrix): If a line ends in a display
5824 vector or the next line starts in a display vector, continue
5825 redrawing the window even though the character position of
5826 start_row was reached.
5827 (Bug#9771, part 2)
5829 2011-10-18 Chong Yidong <cyd@gnu.org>
5831 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
5832 with nobreak-char-display too.
5834 2011-10-18 Eli Zaretskii <eliz@gnu.org>
5836 Fix part 3 of bug#9771.
5837 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
5838 (bidi_resolve_neutral): Don't enter the expensive loop looking for
5839 non-neutral characters if the current character is a paragraph
5840 separator (a.k.a. Newline). This avoids running the same
5841 expensive loop twice, once when we consume the preceding newline
5842 and the other time when the line actually needs to be displayed.
5843 Avoid the loop when we see neutrals on the base embedding level
5844 following a character whose directionality is the same as the
5845 paragraph's. This avoids running the expensive loop when a line
5846 ends in a long sequence of neutrals, like control characters.
5847 Add assertion against STRONG_AL type. Slightly rearrange code
5848 that determines the type of a neutral given the first non-neutral
5849 that follows it.
5850 (bidi_level_of_next_char): Set next_en_pos to zero when
5851 invalidating its info.
5853 2011-10-17 Eli Zaretskii <eliz@gnu.org>
5855 * xdisp.c (push_display_prop): Determine whether to record string
5856 or buffer position by IT->string, not by IT->method. Allow
5857 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
5858 (move_it_vertically_backward): Don't look for character position
5859 immediately after the newline when in a continuation line.
5860 (Bug#9771, part 1)
5862 2011-10-15 Martin Rudalics <rudalics@gmx.at>
5864 * window.c (coordinates_in_window): Rewrite and delabelize
5865 vertical border check. (Bug#5357) (Bug#9618)
5867 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
5869 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
5870 errors in XSetWindowBorder (bug#9310).
5872 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
5874 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
5875 avoid crash when xmalloc overrun checking is enabled.
5877 2011-10-13 Eli Zaretskii <eliz@gnu.org>
5879 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
5880 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
5881 cursor motion with <left> and <right> arrow keys.
5883 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
5884 some callers set that themselves.
5886 2011-10-12 Eli Zaretskii <eliz@gnu.org>
5888 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
5889 display string and the previous row comes from the same string and
5890 is empty. (Bug#9739) (Bug#9738)
5892 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
5894 * doc.c (get_doc_string): Encode file name (bug#9735).
5896 2011-10-12 Eli Zaretskii <eliz@gnu.org>
5898 * bidi.c (bidi_level_of_next_char):
5899 * xdisp.c (get_visually_first_element): Remove old incorrect
5900 comments regarding the Unicode Line Separator character.
5902 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
5904 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
5906 * alloc.c (Fgc_status): Do not access beyond zombies array
5907 boundary if nzombies > MAX_ZOMBIES.
5908 * alloc.c (dump_zombies): Add missing format specifier.
5910 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
5912 * xdisp.c (set_cursor_from_row): Simplify conditionals,
5913 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
5915 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
5916 Some packages use them to denote characters with modifiers.
5918 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
5920 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
5921 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
5922 matching a pp-number. Rename parameter var to var1.
5924 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
5926 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
5928 2011-10-08 Glenn Morris <rgm@gnu.org>
5930 * callint.c (Fcall_interactively): Give a more explicit error for the
5931 'c' case with a non-character input. (Bug#8479)
5933 2011-10-08 Eli Zaretskii <eliz@gnu.org>
5935 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
5936 lines.
5937 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
5938 lines that are hscrolled on the left.
5940 * dispnew.c (buffer_posn_from_coords): Account for a possible
5941 presence of header-line. (Bug#4426)
5943 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
5945 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
5946 Don't advertise functionality which we discourage or doesn't work.
5948 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
5950 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
5951 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
5952 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
5953 this makes Emacs dump core during garbage collection on rare
5954 occasions. sizeof is obviously inferior to offsetof here, so
5955 stick with offsetof.
5956 (GC_POINTER_ALIGNMENT): New macro.
5957 (mark_memory): Omit 3rd (offset) arg; caller changed.
5958 Don't assume EMACS_INT alignment is the same as pointer alignment.
5960 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
5962 * keyboard.c (read_key_sequence_remapped): New var.
5963 (read_key_sequence): Compute remapping in the right buffer.
5964 (command_loop_1): Use read_key_sequence's remapping directly.
5966 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5968 * dired.c (file_name_completion): Don't expand file name.
5969 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
5970 before checking file name handler.
5972 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
5973 they've been requested explicitly (bug#9591).
5975 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
5977 * keymap.c (Fsingle_key_description): Use make_specified_string
5978 instead of build_string to build string from push_key_description.
5979 (Bug#5193)
5981 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
5983 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
5984 This fixes a Y2038 bug on 64-bit hosts.
5985 * buffer.c (reset_buffer):
5986 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
5987 (Fclear_buffer_auto_save_failure):
5988 Use 0, not -1, to represent an unset failure time, since time_t
5989 might not be signed.
5991 Remove dependency on glibc malloc internals.
5992 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5993 Move back here from lisp.h, but with their new implementations.
5994 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5995 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
5996 * charset.c (charset_table_init): New static var.
5997 (syms_of_charset): Use it instead of xmalloc. This removes a
5998 dependency on glibc malloc internals. See Eli Zaretskii's comment in
5999 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
6000 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6001 Move back to alloc.c.
6002 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6003 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
6005 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
6007 * nsterm.m (windowDidResize): Call x_set_window_size only when
6008 ns_in_resize is true. Otherwise set pixelwidth/height and
6009 call change_frame_size (Bug#9628).
6011 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6013 Port --enable-checking=all to Fedora 14 x86-64.
6014 * charset.c (syms_of_charset): Also account for glibc malloc's
6015 internal overhead when calculating the initial malloc maximum.
6017 Port --enable-checking=all to Fedora 14 x86.
6018 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6019 Move to lisp.h.
6020 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
6021 (overrun_check_realloc, overrun_check_free):
6022 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
6023 That way, xmalloc returns a properly-aligned pointer even if
6024 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
6025 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
6026 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
6027 into account when calculating the initial malloc maximum.
6028 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6029 Move here from alloc.c, so that charset.c can use it too.
6030 Properly align; the old code wasn't right for common 32-bit hosts
6031 when configured with --enable-checking=all.
6032 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6033 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
6035 2011-09-29 Eli Zaretskii <eliz@gnu.org>
6037 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
6038 use EDOM.
6040 2011-09-28 Eli Zaretskii <eliz@gnu.org>
6042 * xdisp.c (compute_display_string_end): If there's no display
6043 string at CHARPOS, return -1.
6045 * bidi.c (bidi_fetch_char): When compute_display_string_end
6046 returns a negative value, treat the character as a normal
6047 character not covered by a display string. (Bug#9624)
6049 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
6051 * lread.c (Fread_from_string): Fix typo in docstring.
6053 2011-09-27 Eli Zaretskii <eliz@gnu.org>
6055 * xdisp.c (handle_invisible_prop): If invisible text ends on a
6056 newline, reseat the iterator instead of bidi-iterating there one
6057 character at a time. (Bug#9610)
6058 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
6059 TO_CHARPOS if the bidi iterator is at base embedding level.
6061 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
6063 * lread.c (readevalloop): Use correct code for NBSP.
6064 (read1): Likewise. (Bug#9608)
6066 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
6068 * dbusbind.c (Fdbus_register_signal): When service is not
6069 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
6071 2011-09-25 Glenn Morris <rgm@gnu.org>
6073 * buffer.c (truncate-lines): Doc fix.
6075 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
6077 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
6078 (Fset_window_next_buffers): Doc fix.
6080 2011-09-24 Glenn Morris <rgm@gnu.org>
6082 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
6084 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
6086 Fix minor problems found by static checking.
6087 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
6088 * indent.c (Fvertical_motion): Fix == vs = typo.
6090 2011-09-24 Eli Zaretskii <eliz@gnu.org>
6092 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
6093 Default value is now t. Doc fix.
6095 * indent.c (Fvertical_motion): Compute and apply the overshoot
6096 logic when moving up, not only when moving down. Fix the
6097 confusing name and values of the it_overshoot_expected variable;
6098 logic changes accordingly. (Bug#9254) (Bug#9549)
6100 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
6101 CHARPOS is covered by a display string which includes newlines.
6102 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
6103 is covered by a display string with embedded newlines.
6105 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
6107 * dbusbind.c (Fdbus_register_signal): Add match rule to
6108 Vdbus_registered_objects_table. (Bug#9581)
6109 (Fdbus_register_method, Vdbus_registered_objects_table):
6110 Fix docstring.
6112 2011-09-24 Jim Meyering <meyering@redhat.com>
6114 do not ignore write error for any output size
6115 The previous change was incomplete.
6116 While it makes emacs --batch detect the vast majority of stdout
6117 write failures, errors were still ignored whenever the output size is
6118 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
6119 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
6120 && echo FAIL: ignored write error
6121 FAIL: ignored write error
6122 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
6123 && echo FAIL: ignored write error
6124 FAIL: ignored write error
6125 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
6127 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
6129 * emacs.c (Fkill_emacs): In noninteractive mode exit
6130 non-successfully if a write error occurred on stdout. (Bug#9574)
6132 2011-09-21 Eli Zaretskii <eliz@gnu.org>
6134 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
6135 the xassert test.
6137 * dispextern.h (struct it): Update the comment documenting what
6138 can it->OBJECT be.
6140 2011-09-20 Eli Zaretskii <eliz@gnu.org>
6142 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
6143 a display string, extend search for cursor position to end of row.
6144 (find_row_edges): If the row ends in a newline from a display
6145 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
6146 Handle the case of a display string with multiple newlines.
6147 (Fcurrent_bidi_paragraph_direction): Fix search for previous
6148 non-empty line. Fixes confusing cursor motion with arrow keys at
6149 the beginning of a line that starts with whitespace.
6151 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
6153 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
6154 (bug#9493).
6156 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
6158 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
6159 boolean (Bug#9154).
6161 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6163 * xdisp.c (display_line): Record maximum and minimum buffer
6164 positions even if no glyphs were produced (e.g., by a zero-width
6165 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
6166 buffer positions that will be removed from the glyph row because
6167 they don't fit.
6168 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
6169 column is beyond frame width: don't subtract 1 "pixel" when
6170 computing width of the stretch.
6171 (reseat_at_next_visible_line_start): Undo the change made on
6172 2011-09-17 that saved paragraph information and restored it after
6173 the call to `reseat'. (Bug#9545)
6175 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6177 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
6178 and turn window cursor on if cleared (Bug#9415).
6180 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
6182 * search.c (boyer_moore): Take unibyte characters from pattern
6183 literally. (Bug#9458)
6185 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6187 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
6189 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
6191 Fix minor problem found by static checking.
6192 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
6193 initialized, to pacify gcc -Wuninitialized.
6195 * fileio.c: Report proper errno when syscall falls.
6196 (Finsert_file_contents): Save and restore errno,
6197 so that report_file_error outputs the correct diagnostic.
6198 (Fwrite_region) [CLASH_DETECTION]: Likewise.
6200 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6202 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
6204 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6206 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
6207 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
6209 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6211 * xdisp.c (reseat_at_next_visible_line_start): Keep information
6212 about the current paragraph and restore it after the call to reseat.
6214 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
6215 (bidi_find_paragraph_start): Search back for paragraph beginning
6216 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
6217 (bidi_move_to_visually_next): Only trigger paragraph-related
6218 computations when the last character is a newline or at EOB, not
6219 just any NEUTRAL_B. (Bug#9470)
6221 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
6222 truncated lines if point is covered by a display string. (Bug#9524)
6224 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
6226 * xselect.c: Relax test for outgoing X longs (Bug#9498).
6227 (cons_to_x_long): New function.
6228 (lisp_data_to_selection_data): Use it. Correct the test for
6229 short-versus-long data; it was negated. Break out of vector
6230 loop, for efficiency, when a long datum is discovered.
6232 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
6234 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
6236 2011-09-16 Eli Zaretskii <eliz@gnu.org>
6238 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
6239 GCC PR/17406) by declaring this function with external scope.
6241 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6243 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
6244 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
6246 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
6248 * editfns.c (Fformat): Correctly handle text properties on "%%".
6250 2011-09-15 Eli Zaretskii <eliz@gnu.org>
6252 * xterm.c (x_draw_composite_glyph_string_foreground):
6253 * w32term.c (x_draw_composite_glyph_string_foreground):
6254 * term.c (encode_terminal_code):
6255 * composite.c (composition_update_it, get_composition_id):
6256 * xdisp.c (get_next_display_element)
6257 (fill_composite_glyph_string): Add comments about special meaning
6258 of TAB characters in a composition.
6260 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6262 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
6263 This occurs when processing a multibyte format.
6264 Problem reported by Wolfgang Jenker.
6266 2011-09-15 Johan Bockgård <bojohan@gnu.org>
6268 * xdisp.c (try_cursor_movement): Only check for exact match if
6269 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
6271 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6273 Remove unused external symbols.
6274 * dispextern.h (calc_pixel_width_or_height): Remove decl.
6275 * xdisp.c (calc_pixel_width_or_height): Now static.
6276 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
6277 * indent.c (check_display_width):
6278 * w32term.c: Fix comment to match code.
6279 * xterm.c, xterm.h (x_catching_errors): Remove.
6281 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6283 * xselect.c: Use signed conversions more consistently (Bug#9498).
6284 (selection_data_to_lisp_data): Assume incoming selection data are
6285 signed integers, not unsigned. This is to be consistent with
6286 outgoing selection data, which was modified to use signed integers
6287 in as part of the fix to Bug#9196 in response to Jan D.'s comment
6288 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
6289 expects long, not unsigned long.
6291 2011-09-14 Eli Zaretskii <eliz@gnu.org>
6293 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
6294 computation of loop end. Reported by Johan Bockgård
6295 <bojohan@gnu.org>.
6297 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
6299 * frame.c (Fother_visible_frames_p): Function deleted.
6301 2011-09-12 Eli Zaretskii <eliz@gnu.org>
6303 * indent.c (compute_motion): Process display vector front to back
6304 rather than the other way around. (Bug#2496)
6306 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6308 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
6310 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
6312 * minibuf.c (Fread_from_minibuffer): Doc fix.
6314 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6316 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
6317 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
6319 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
6321 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
6322 value for non-existent files.
6324 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6326 * fileio.c (Finsert_file_contents): If the file cannot be opened,
6327 set its "size" to -1. This will set the modtime_size field of
6328 the corresponding buffer to -1, which is what
6329 verify-visited-file-modtime expects for files that do not exist.
6330 (Bug#9139)
6332 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
6334 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
6335 here ...
6336 * lisp.h: ... from here. push_key_description is no longer
6337 defined in keyboard.c, so its declaration should not be in
6338 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
6339 logically belongs with push_key_description.
6341 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
6343 * buffer.h: Include <sys/types.h> instead of <time.h>.
6344 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
6345 Problem reported by Herbert J. Skuhra.
6347 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
6349 * xml.c (parse_region): Make the parsing work for
6350 non-comment-starting XML files again (bug#9144).
6352 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
6354 * image.c (gif_load): Fix calculation of bottom and right corner.
6355 (Bug#9468)
6357 2011-09-10 Eli Zaretskii <eliz@gnu.org>
6359 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
6360 redisplay in small windows.
6362 2011-09-09 Eli Zaretskii <eliz@gnu.org>
6364 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
6366 2011-09-08 Martin Rudalics <rudalics@gmx.at>
6368 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
6369 Operate on live windows only.
6371 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
6373 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
6375 2011-09-07 Eli Zaretskii <eliz@gnu.org>
6377 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
6378 only under bidi iteration.
6380 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
6382 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
6384 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6386 isnan: Fix porting problem to Solaris 10 with bundled gcc.
6387 Without this fix, the command to link temacs failed due to an
6388 undefined symbol __builtin_isnan. This is because
6389 /usr/include/iso/math_c99.h #defines isnan(x) to
6390 __builtin_isnan(x), but the bundled gcc, which identifies itself
6391 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
6392 a __builtin_isnan.
6393 * floatfns.c (isnan): #undef, and then #define to a clone of
6394 what's in data.c.
6395 (Fisnan): Always define, since it's always available now.
6396 (syms_of_floatfns): Always define isnan at the Lisp level.
6398 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6400 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
6402 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6404 * fileio.c: Fix bugs with large file offsets (Bug#9428).
6405 The previous code assumed that file offsets (off_t values) fit in
6406 EMACS_INT variables, which is not true on typical 32-bit hosts.
6407 The code messed up by falsely reporting buffer overflow in cases
6408 such as (insert-file-contents "big" nil 1 2) into an empty buffer
6409 when "big" contains more than 2**29 bytes, even though this
6410 inserts just one byte and does not overflow the buffer.
6411 (Finsert_file_contents): Store file offsets as off_t
6412 values, not as EMACS_INT values. Check for overflow when
6413 converting between EMACS_INT and off_t. When checking for
6414 buffer overflow or for overlap, take the offsets into account.
6415 Don't use EMACS_INT for small values where int suffices.
6416 When checking for overlap, fix a typo: ZV was used where
6417 ZV_BYTE was intended.
6418 (Fwrite_region): Don't assume off_t fits into 'long'.
6419 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
6421 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
6423 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
6425 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6427 sprintf-related integer and memory overflow issues (Bug#9412).
6429 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
6430 (esprintf, exprintf, evxprintf): New functions.
6431 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
6432 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
6433 (modify_event_symbol): Do not assume that the length of
6434 name_alist_or_stem is safe to alloca and fits in int.
6435 (Fexecute_extended_command): Likewise for function name and binding.
6436 (Frecursion_depth): Wrap around reliably on integer overflow.
6437 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
6438 since some callers pass EMACS_INT values.
6439 (Fsingle_key_description): Don't crash if symbol name contains more
6440 than MAX_ALLOCA bytes.
6441 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
6442 (get_minibuffer): Arg is now EMACS_INT, not int.
6443 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
6444 (esprintf, exprintf, evxprintf): New decls.
6445 * window.h (command_loop_level, minibuf_level): Reflect API changes.
6447 * dbusbind.c (signature_cat): New function.
6448 (xd_signature, Fdbus_register_signal):
6449 Do not overrun buffer; instead, report string overflow.
6451 * dispnew.c (add_window_display_history): Don't overrun buffer.
6452 Truncate instead; this is OK since it's just a log.
6454 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
6455 even if the time zone offset is outlandishly large.
6456 Don't mishandle offset == INT_MIN.
6458 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
6459 when creating daemon; the previous buffer-overflow check was incorrect.
6461 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
6462 which has the guts of the old verror function.
6464 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
6465 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
6467 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
6468 (font_unparse_xlfd): Don't blindly alloca long strings.
6469 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
6470 fits in int, when using sprintf. Use single snprintf to count
6471 length of string rather than counting it via multiple sprintfs;
6472 that's simpler and more reliable.
6473 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
6474 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
6475 sprintf, in case result does not fit in int.
6477 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
6478 (fontset_from_font): Print it.
6480 * frame.c (tty_frame_count): Now printmax_t, not int.
6481 (make_terminal_frame, set_term_frame_name): Print it.
6482 (x_report_frame_params): In X, window IDs are unsigned long,
6483 not signed long, so print them as unsigned.
6484 (validate_x_resource_name): Check for implausibly long names,
6485 and don't assume name length fits in 'int'.
6486 (x_get_resource_string): Don't blindly alloca invocation name;
6487 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
6488 not fit in int.
6490 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
6491 (xg_check_special_colors, xg_set_geometry):
6492 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
6494 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
6495 Use esprintf, not sprintf, in case result does not fit in int.
6497 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6498 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
6499 it as a large positive number.
6500 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
6501 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6503 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
6504 in case result does not fit in int.
6506 * print.c (float_to_string): Detect width overflow more reliably.
6507 (print_object): Make sprintf buffer a bit bigger, to avoid potential
6508 buffer overrun. Don't assume list length fits in 'int'. Treat
6509 print length of 0 as 0, not as infinity; to be consistent with other
6510 uses of print length in this function. Don't overflow print length
6511 index. Don't assume hash table size fits in 'long', or that
6512 vectorlike size fits in 'unsigned long'.
6514 * process.c (make_process): Use printmax_t, not int, to format
6515 process-name gensyms.
6517 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
6519 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
6520 to avoid potential buffer overrun.
6522 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
6523 if X resource line is longer than 512 bytes.
6525 * xfns.c (x_window): Make sprintf buffer a bit bigger
6526 to avoid potential buffer overrun.
6528 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
6530 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
6532 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6534 Integer overflow fixes for scrolling, etc.
6535 Without these, Emacs silently mishandles large integers sometimes.
6536 For example, "C-u 4294967297 M-x recenter" was treated as if
6537 it were "C-u 1 M-x recenter" on a typical 64-bit host.
6539 * xdisp.c (try_window_id): Check Emacs fixnum range before
6540 converting to 'int'.
6542 * window.c (window_scroll_line_based, Frecenter):
6543 Check that an Emacs fixnum is in range before assigning it to 'int'.
6544 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
6545 values converted from Emacs fixnums.
6546 (Frecenter): Don't wrap around a line count if it is out of 'int'
6547 range; instead, treat it as an extreme value.
6548 (Fset_window_configuration, compare_window_configurations):
6549 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
6551 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
6552 that can exceed INT_MAX. Check that EMACS_INT value is in range
6553 before assigning it to the (possibly-narrower) index.
6554 (match_limit): Don't assume that a fixnum can fit in 'int'.
6556 * print.c (print_object): Use ptrdiff_t, not int, for index that can
6557 exceed INT_MAX.
6559 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
6560 (Fvertical_motion): Don't wrap around LINES values that don't fit
6561 in 'int'. Instead, treat them as extreme values. This is good
6562 enough for windows, which can't have more than INT_MAX lines anyway.
6564 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
6566 * Require libxml/parser.h to avoid compilation warning.
6568 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
6570 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
6571 since this reportedly can destroy thread storage.
6573 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
6575 * syntax.c (find_defun_start): Update all cache variables if
6576 exiting early (Bug#9401).
6578 2011-08-30 Eli Zaretskii <eliz@gnu.org>
6580 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
6582 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
6583 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
6584 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
6586 * term.c (tty_append_glyph): New function.
6587 (produce_stretch_glyph): Static function and its prototype deleted.
6589 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
6590 Add prototypes.
6592 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
6594 * image.c (parse_image_spec): Check for nonnegative, not for positive,
6595 when checking :margin (Bug#9390).
6596 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
6597 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
6598 so that the name doesn't mislead. All uses changed.
6600 2011-08-28 Johan Bockgård <bojohan@gnu.org>
6602 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
6603 set_tty_hooks.
6605 2011-08-27 Eli Zaretskii <eliz@gnu.org>
6607 * xdisp.c (move_it_to): Don't bail out early when reaching
6608 position beyond to_charpos, if we are scanning backwards.
6609 (move_it_vertically_backward): When DY == 0, make sure we get to
6610 the first character in the line after the newline.
6612 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
6614 * ccl.c: Improve and simplify overflow checking (Bug#9196).
6615 (ccl_driver): Do not generate an out-of-range pointer.
6616 (Fccl_execute_on_string): Remove unnecessary check for
6617 integer overflow, noted by Stefan Monnier in
6618 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
6619 Remove a FIXME that didn't need fixing.
6620 Simplify the newly-introduced buffer reallocation code.
6622 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
6624 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
6626 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
6628 Integer and memory overflow issues (Bug#9196).
6630 * doc.c (get_doc_string): Rework so that
6631 get_doc_string_buffer_size is the actual buffer size, rather than
6632 being 1 less than the actual buffer size; this makes xpalloc more
6633 convenient.
6635 * image.c (x_allocate_bitmap_record, cache_image):
6636 * xselect.c (Fx_register_dnd_atom):
6637 Simplify previous changes by using xpalloc.
6639 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
6640 since either will do and ptrdiff_t is convenient with xpalloc.
6642 * charset.c (charset_table_size)
6643 (struct charset_sort_data.priority): Now ptrdiff_t.
6644 (charset_compare): Don't overflow if priorities differ greatly.
6645 (Fsort_charsets): Don't assume list length fits in int.
6646 Check for size-calculation overflow when allocating sort data.
6647 (syms_of_charset): Allocate an initial charset table that is
6648 just under 64 KiB, to avoid problems with glibc malloc and mmap.
6650 * cmds.c (internal_self_insert): Check for size-calculation overflow.
6652 * composite.h (struct composition.glyph_len): Now int, not unsigned.
6653 The actual value is always <= INT_MAX, and leaving it unsigned made
6654 overflow checking harder.
6656 * dispextern.h (struct glyph_matrix.rows_allocated)
6657 (struct face_cache.size): Now ptrdiff_t, for convenience in use
6658 with xpalloc. The values are still always <= INT_MAX.
6660 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
6662 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
6663 (SAFE_NALLOCA): New macro.
6665 * region-cache.c (struct boundary.pos, find_cache_boundary)
6666 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
6667 (set_cache_region, invalidate_region_cache)
6668 (revalidate_region_cache, know_region_cache, region_cache_forward)
6669 (region_cache_backward, pp_cache):
6670 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
6671 so that ptrdiff_t * can be passed to xpalloc.
6672 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
6673 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
6674 (pp_cache): Don't assume cache_len fits in int.
6675 * region-cache.h: Adjust extern decls to match.

6690 Don't update size of array until after memory allocation succeeds,
6691 because xmalloc/xrealloc may not return.
6692 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
6693 now that we have proper integer overflow checking.
6694 (record_overlay_string, overlay_strings): Catch overflows when
6695 calculating size of overlay_str_buf.
6697 * callproc.c (Fcall_process): Check for size overflow when
6698 calculating size of args2.

6744 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
6746 * emacs.c (main): Do not reallocate argv, since there is a null at
6747 the end that can be overwritten, and this way there's no need to
6748 worry about size-calculation overflow.
6749 (sort_args): Check for size-calculation overflow.
6751 * eval.c (init_eval_once, grow_specpdl): Don't update size until

6757 Check for integer overflow.
6758 (x_set_alpha): Do not assume XINT fits in int.
6760 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
6761 This is for the members text_lines, text_cols, total_lines, total_cols,
6762 where the system imposes an 'int' limit.

6771 Check for size-calculation overflow.
6772 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
6773 do, as we prefer signed integers.
6774 (id_to_widget.max_size, id_to_widget.used)
6775 (xg_store_widget_in_map, xg_remove_widget_from_map)
6776 (xg_get_widget_from_map, xg_get_scroll_id_for_window)

6861 Check for size calculation overflow.
6862 (cache_face): Treat size calculation overflows as if they were

6878 (X_LONG_MIN): New macros.
6879 Use them to make the following changes clearer.
6880 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
6881 This change doesn't affect the value now, but it may help remind
6882 future maintainers not to raise the value too much later.
6883 (SELECTION_QUANTUM): Remove, replacing with ...
6884 (selection_quantum): ... new function, which avoids overflow.
6885 All uses changed.
6886 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
6887 assumption that selection length fits in 'int'.

6895 Redo calculations to avoid overflow.
6896 (x_reply_selection_request): When sending hint, ceiling it at

6900 (lisp_data_to_selection_data, x_property_data_to_lisp):

6904 Don't store size until memory allocation succeeds.
6905 (x_get_window_property): Plug memory leak on memory exhaustion.
6906 Don't double-block input; malloc is safe here. Don't assume 2**34
6907 - 4 fits in unsigned long. Add an xassert to check
6908 XGetWindowProperty overflow. Be more careful about overflow
6909 calculations, and distinguish size from memory overflow better.

6911 unsigned int is less than INT_MAX.
6912 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

6915 in the range -65535 through -1 fit in an X unsigned short.
6916 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
6917 result parameters unless successful. Rely on cons_to_unsigned
6918 to report problems with elements; the old code wasn't right anyway.
6919 (x_check_property_data): Check for int overflow; we cannot use
6920 a wider type due to X limits.

6953 * lisp.h (hash_lookup, hash_put):
6954 * minibuf.c (Ftest_completion):
6955 Use ptrdiff_t for hash table indexes, not int (which is too
6956 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
6957 32-bit --with-wide-int hosts).
6959 * charset.c (Fdefine_charset_internal): Check for integer overflow.
6960 Add a FIXME comment about memory leaks.

6992 ptrdiff_t and size_t limits.
6994 * keyboard.c: Overflow, signedness and related fixes.
6995 (make_lispy_movement): Use same integer type in forward decl
6996 that is used in the definition.
6997 (read_key_sequence, keyremap_step):
6998 Change bufsize argument back to int, undoing my 2011-03-30 change.

7000 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
7001 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
7002 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
7003 length, not size_t. Use ptrdiff_t for index, not int.
7004 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
7005 possibility of integer overflow.

7032 (png_load, gif_load, svg_load_image):
7033 Prefer int to unsigned where either will do.
7034 (tiff_handler): New function, combining the cores of the
7035 old tiff_error_handler and tiff_warning_handler.
7036 This function is rewritten to use vsnprintf and thereby avoid
7037 stack buffer overflows. It uses only the features of vsnprintf
7038 that are common to both POSIX and native Microsoft.
7039 (tiff_error_handler, tiff_warning_handler): Use it.
7040 (tiff_load, gif_load, imagemagick_load_image):

7044 the integer types that MagickCropImage accepts. Don't assume
7045 Vimagemagick_render_type has a nonnegative value. Don't assume
7046 size_t fits in 'long'.
7047 (gs_load): Use printmax_t to print the widest integers possible.

7050 2011-08-26 Eli Zaretskii <eliz@gnu.org>
7052 * xdisp.c (redisplay_window): Don't force window start if point
7053 will be invisible in the resulting window. (Bug#9324)
7055 2011-08-25 Eli Zaretskii <eliz@gnu.org>
7057 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
7058 the display spec is of the form `(space ...)'.
7059 (handle_display_spec): Return the value returned by
7060 handle_single_display_spec, not just 1 or zero.
7061 (handle_single_display_spec): If the display spec is of the form
7062 `(space ...)', and specifies display in the text area, return 2
7063 rather than 1.
7064 (try_cursor_movement): Check for the need to scroll more
7065 accurately, and prefer exact match for point under bidi.
7066 Don't advance `row' beyond the last row of the window.
7068 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
7069 into disp_prop; all users changed.
7071 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

7084 buffers, return left-to-right.
7085 (set_cursor_from_row): Consider candidate row a win if its glyph
7086 represents a newline and point is on that newline. Fixes cursor
7087 positioning on the newline at EOL of R2L text within L2R
7088 paragraph, and vice versa.
7089 (try_cursor_movement): Check continued rows, in addition to
7090 continuation rows. Fixes unwarranted scroll when point enters a
7091 continued line of R2L text within an L2R paragraph, or vice versa.
7092 (cursor_row_p): Consider the case of point being equal to
7093 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
7094 from the end of a short line to the beginning of a continued line
7095 of R2L text within L2R paragraph.
7096 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

7114 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
7115 extra slot even if the purpose is char-code-property-table.
7117 2011-08-23 Eli Zaretskii <eliz@gnu.org>
7119 * xdisp.c (redisplay_window): When computing centering_position,
7120 account for the height of the header line. (Bug#8874)
7122 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
7123 instead of CHAR_TO_BYTE. Fixes a crash when a completion
7124 candidate is selected by the mouse, and that candidate has a
7125 composed character under the mouse.
7127 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
7128 coordinates reported by pos-visible-in-window-p for a composed
7129 character in column zero.
7131 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

7135 2011-08-22 Eli Zaretskii <eliz@gnu.org>
7137 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
7138 consider it a hit if to_charpos is anywhere in the range of the
7139 composed buffer positions.
7141 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
7143 * image.c (gif_load): Don't assume that each subimage has the same
7144 dimensions as the base image. Handle disposal method that is
7145 "undefined" by the gif spec (Bug#9335).
7147 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
7149 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

7154 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
7155 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
7156 from an Org mode buffer to a Speedbar frame.
7158 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
7159 a composition, take its buffer position from IT->cmp_it.charpos.
7160 Fixes cursor positioning at the beginning of a line that begins
7161 with a composed character.
7163 2011-08-18 Eli Zaretskii <eliz@gnu.org>
7165 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
7166 character bidirectional type, use STRONG_L instead. Fixes crashes
7167 in a buffer produced by `describe-categories'.
7169 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
7170 members before the level stack, so they would be saved and
7171 restored when copying iterator state. Fixes incorrect reordering
7172 around TABs covered by display properties.
7174 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
7176 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

7181 (internal_condition_case_2, internal_condition_case_n):
7182 Remove unnecessary aborts (Bug#9081).
7184 2011-08-17 Eli Zaretskii <eliz@gnu.org>
7186 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
7187 has no `load' handler, try opening the file locally. (Bug#9311)
7189 2011-08-16 Ken Brown <kbrown@cornell.edu>
7191 * gmalloc.c: Expand comment.
7193 2011-08-16 Eli Zaretskii <eliz@gnu.org>
7195 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
7196 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
7198 2011-08-16 Ken Brown <kbrown@cornell.edu>
7200 Fix memory allocation problems in Cygwin build (Bug#9273).

7206 New variables.
7207 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
7208 dumped emacs.
7209 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
7210 in the static heap.
7211 [CYGWIN] (special_realloc): New function.
7212 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
7213 requests to realloc storage in the static heap.

7221 * bidimirror.h:
7222 * biditype.h: Remove file.
7223 * makefile.w32-in ($(BLD)/bidi.$(O)):
7224 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
7226 * dispextern.h: Fix a typo in the comment to bidi_type_t.
7228 * chartab.c: Improve commentary for the uniprop_table API.
7230 * bidi.c (bidi_paragraph_init): Support zero value of
7231 bidi_ignore_explicit_marks_for_paragraph_level.

7233 biditype.h and bidimirror.h.
7235 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
7236 coordinates of the iterator when restoring from ppos_it.
7237 (Bug#9296)
7239 2011-08-14 Kenichi Handa <handa@m17n.org>
7241 * process.c (create_process): Call setup_process_coding_systems
7242 after the pid of the process is set to -1 (Bug#8162).
7244 2011-08-14 Eli Zaretskii <eliz@gnu.org>
7246 * xdisp.c (move_it_in_display_line_to): Don't invoke
7247 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
7248 ppos_it. Fixes vertical cursor motion when line beginning is
7249 covered by an image. (Bug#9296)
7251 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
7253 * nsterm.h (ns_run_ascript): Declare.

7256 * nsfns.m (as_script, as_result, as_status): New static variables.
7257 (ns_run_ascript): New function.
7258 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
7259 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
7260 the event loop. Get status from as_status (Bug#7276).
7262 * nsterm.m (sendEvent): If event is NSApplicationDefined and
7263 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
7264 the event loop (Bug#7276).
7266 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
7268 * gnutls.c (QCgnutls_bootprop_priority)
7269 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
7270 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
7271 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
7272 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
7273 (QCgnutls_bootprop_verify_hostname_error)
7274 (QCgnutls_bootprop_callbacks_verify): Rename from
7275 Qgnutls_bootprop_..., all uses changed.
7277 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
7278 uses changed.
7280 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
7282 * xfaces.c (Qframe_set_background_mode): Now static.
7283 * dispextern.h (Qframe_set_background_mode): Remove decl.
7285 * process.c (Fnetwork_interface_info): Declare local only if needed.
7287 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
7289 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
7290 (Fnetwork_interface_list): Allocate in increments of bytes instead
7291 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
7292 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
7293 sockaddr.
7294 (struct ifflag_def): notrailers is smart on OSX.
7295 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
7296 Get hardware address with getifaddrs if available.
7298 2011-08-12 Eli Zaretskii <eliz@gnu.org>
7300 * xdisp.c (iterate_out_of_display_property): xassert that
7301 IT->position is set to within IT->object's boundaries. Break from
7302 the loop as soon as EOB is reached; avoids infloops in redisplay
7303 when IT->position is set up wrongly due to some bug.
7304 Set IT->current to match the bidi iterator unconditionally.
7305 (push_display_prop): Allow GET_FROM_STRING as IT->method on
7306 entry. Force push_it to save on the stack the current
7307 buffer/string position, to be restored by pop_it. Fix flags in
7308 the iterator structure wrt the object coming from a display
7309 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
7310 properties. (Bug#9284)
7312 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
7314 * fontset.c (fontset_get_font_group): Add proper type checks.

7327 no-display-properties-and-no-overlays under bidi display.
7328 Set disp_pos in the bidi iterator to avoid searches for display
7329 properties and overlays.
7331 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
7333 * editfns.c (Fset_time_zone_rule): Document relationship with the
7334 setenv function.

7337 the font entity extracted from the cache (Bug#8109).
7339 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
7341 * composite.c (autocmp_chars): Don't reset point. That is done by
7342 restore_point_unwind (Bug#5984).
7344 2011-08-07 Juri Linkov <juri@jurta.org>
7346 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
7347 to show the arg `TIME' instead of `TIMEVAL'.
7349 2011-08-06 Eli Zaretskii <eliz@gnu.org>
7351 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
7352 display property strides EOL and includes a newline, as in
7353 longlines-mode. (Bug#9254)
7354 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
7355 word-wrap under bidirectional display. (Bug#9224)
7357 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
7358 is non-zero, even if the data buffer is NULL. Fixes a crash in
7359 vertical-motion with longlines-mode. (Bug#9254)
7361 2011-08-05 Eli Zaretskii <eliz@gnu.org>
7363 * bidi.c <bidi_cache_total_alloc>: Now static.
7364 (bidi_initialize): Initialize bidi_cache_total_alloc.
7366 * xdisp.c (display_line): Release buffer allocated for shelved bidi
7367 cache. (Bug#9221)
7369 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
7370 amount allocated this far in `bidi_cache_total_alloc'.
7371 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
7372 non-zero, only free the data buffer without restoring the cache
7373 contents. All callers changed.
7375 * dispextern.h (bidi_unshelve_cache): Update prototype.
7377 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
7378 (move_it_in_display_line, move_it_to)
7379 (move_it_vertically_backward, move_it_by_lines): Replace the call
7380 to xfree to an equivalent call to bidi_unshelve_cache.
7381 (move_it_in_display_line_to): Fix logic of returning
7382 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
7384 2011-08-05 Eli Zaretskii <eliz@gnu.org>
7386 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
7387 came from a string character with a `cursor' property. (Bug#9229)
7389 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
7391 * Makefile.in (LIB_PTHREAD): New variable.
7392 (LIBES): Add LIB_PTHREAD (Bug#9216).
7394 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
7395 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
7397 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
7399 * regex.c (re_iswctype): Remove some redundant boolean conversions.
7401 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
7403 * xterm.c (x_find_topmost_parent): New function.
7404 (x_set_frame_alpha): Find topmost parent window with
7405 x_find_topmost_parent and set the property there also (bug#9181).
7406 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
7408 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
7410 * callproc.c (Fcall_process): Avoid vfork clobbering
7411 the local vars buffer, coding_systems, current_dir.
7413 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
7415 * keymap.c (Fmake_composed_keymap): Move to subr.el.
7417 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
7419 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
7420 so that it is not optimized away.
7422 * xdisp.c (compute_display_string_pos): Remove unused local.
7424 2011-08-02 Eli Zaretskii <eliz@gnu.org>
7426 Fix slow cursor motion and scrolling in large buffers with
7427 selective display, like Org Mode buffers. (Bug#9218)
7429 * dispextern.h (struct bidi_it): New member disp_prop_p.
7431 * xdisp.c: Remove one-slot cache of display string positions.
7432 (compute_display_string_pos): Accept an additional argument
7433 DISP_PROP_P; callers changed. Scan at most 5K characters forward
7434 for a display string or property. If found, set DISP_PROP_P
7435 non-zero.
7437 * bidi.c (bidi_fetch_char): Accept an additional argument
7438 DISP_PROP_P, and pass it to compute_display_string_pos.
7439 Only handle text covered by a display string if DISP_PROP_P is returned
7440 non-zero. All callers of bidi_fetch_char changed.
7442 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
7444 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
7446 2010-12-03 Don March <don@ohspite.net>
7448 * keymap.c (Fdefine_key): Fix non-prefix key error message when
7449 last character M-[char] is translated to ESC [char] (bug#7541).
7451 2011-08-02 Kenichi Handa <handa@m17n.org>
7453 * lisp.h (uniprop_table): Extern it.
7455 * chartab.c (uniprop_table): Make it non-static.
7457 2011-08-01 Eli Zaretskii <eliz@gnu.org>
7459 * xdisp.c (forward_to_next_line_start): Accept additional argument
7460 BIDI_IT_PREV, and store into it the state of the bidi iterator had
7461 on the newline.
7462 (reseat_at_next_visible_line_start): Use the bidi iterator state
7463 returned by forward_to_next_line_start to restore the state of
7464 it->bidi_it after backing up to previous newline. (Bug#9212)
7466 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
7468 * regex.c (re_comp): Protoize.
7469 (re_exec): Fix return type.
7470 (regexec): Fix type of `ret'. (Bug#9203)
7472 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7474 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
7475 This is needed if max-image-size is a floating-point number.
7477 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
7479 * print.c (print_object): Print empty symbol as ##.
7481 * lread.c (read1): Read ## as empty symbol.
7483 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
7485 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
7486 setting frame foreground color (Bug#9175).
7487 (x_set_background_color): Likewise.
7489 * nsmenu.m (-setText): Size tooltip dimensions precisely to
7490 contents (Bug#9176).
7491 (EmacsTooltip -init): Remove bezels and add shadows to
7492 tooltip windows.
7494 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
7495 or scroll bar (Bug#8470).
7497 * nsfont.m (nsfont_open): Remove assignment to voffset and
7498 unnecessary vars hshink, expand, hd, full_height, min_height.
7499 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
7501 * nsterm.h (nsfont_info): Remove voffset field.
7503 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
7505 Implement strike-through and overline on NextStep (Bug#8863).
7507 * nsfont.m (nsfont_open): Use underline position provided by font,
7508 instead of hard-coded value of 2.
7509 (nsfont_draw): Call ns_draw_text_decoration instead.
7511 * nsterm.h: Add declaration for ns_draw_text_decoration.
7513 * nsterm.m (ns_draw_text_decoration): New function for drawing

7517 accommodate underlining, etc.
7519 2011-07-28 Eli Zaretskii <eliz@gnu.org>
7521 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
7522 default.
7524 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7526 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
7527 Without this fix, if a signal arrives just after memory fills up,
7528 'malloc' might be invoked reentrantly.
7530 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
7531 In other words, assume that every image size is allowed, on non-X
7532 hosts. This assumption is probably wrong, but it lets Emacs compile.
7534 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
7536 * regex.c (re_iswctype): Convert return values to boolean.
7538 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
7540 * xdisp.c (compute_display_string_pos): Don't use cached display
7541 string position if the buffer had its restriction changed.
7542 (Bug#9184)
7544 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7546 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
7548 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7550 Integer signedness and overflow and related fixes. (Bug#9079)
7552 * bidi.c: Integer size and overflow fixes.
7553 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
7554 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
7555 (bidi_cache_find_level_change, bidi_cache_ensure_space)
7556 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
7557 (bidi_find_other_level_edge):
7558 Use ptrdiff_t instead of EMACS_INT where either will do.
7559 This works better on 32-bit hosts configured --with-wide-int.
7560 (bidi_cache_ensure_space): Check for size-calculation overflow.
7561 Use % rather than repeated addition, for better worst-case speed.
7562 Don't set bidi_cache_size until after xrealloc returns, because it
7563 might not return.
7564 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
7565 (bidi_cache_ensure_space): Also check that the bidi cache size
7566 does not exceed that of the largest Lisp string or buffer. See Eli
7567 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
7569 * alloc.c (__malloc_size_t): Remove.
7570 All uses replaced by size_t. See Andreas Schwab's note
7571 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
7573 * image.c: Improve checking for integer overflow.
7574 (check_image_size): Assume that f is nonnull, since
7575 it is always nonnull in practice. This is one less thing to
7576 worry about when checking for integer overflow later.
7577 (x_check_image_size): New function, which checks for integer
7578 overflow issues inside X.
7579 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
7580 This removes the need for a memory_full check.
7581 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
7582 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
7583 (xbm_read_bitmap_data): Change locals back to 'int', since
7584 their values must fit in 'int'.
7585 (xpm_load_image, png_load, tiff_load):
7586 Invoke x_create_x_image_and_pixmap earlier,
7587 to avoid much needless work if the image is too large.
7588 (tiff_load): Treat overly large images as if
7589 x_create_x_image_and_pixmap failed, not as malloc failures.
7590 (gs_load): Use x_check_image_size.
7592 * gtkutil.c: Omit integer casts.
7593 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
7594 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
7596 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
7598 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
7599 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
7600 would wrongly return t on a 64-bit host.
7602 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
7603 The plain *_OVERFLOW macros run afoul of GCC bug 49705
7604 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
7605 and therefore cause GCC to emit a bogus diagnostic in some cases.
7607 * image.c: Integer signedness and overflow and related fixes.
7608 This is not an exhaustive set of fixes, but it's time to
7609 record what I've got.
7610 (lookup_pixel_color, check_image_size): Remove redundant decls.
7611 (check_image_size): Don't assume that arbitrary EMACS_INT values
7612 fit in 'int', or that arbitrary 'double' values fit in 'int'.
7613 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
7614 (tiff_load, imagemagick_load_image):
7615 Check for overflow in size calculations.
7616 (x_create_x_image_and_pixmap): Remove unnecessary test for
7617 xmalloc returning NULL; that can't happen.
7618 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
7619 (xpm_color_bucket): Use better integer hashing function.
7620 (xpm_cache_color): Don't possibly over-allocate memory.
7621 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
7622 (gif_memory_source):
7623 Use ptrdiff_t, not int or size_t, to record sizes.
7624 (png_load): Don't assume values greater than 2**31 fit in 'int'.
7625 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
7626 either works, as we prefer signed integers.
7627 (tiff_read_from_memory, tiff_write_from_memory):
7628 Return tsize_t, not size_t, since that's what the TIFF API wants.
7629 (tiff_read_from_memory): Don't fail simply because the read would
7630 go past EOF; instead, return a short read.
7631 (tiff_load): Omit no-longer-needed casts.
7632 (Fimagemagick_types): Don't assume size fits into 'int'.
7634 Improve hashing quality when configured --with-wide-int.
7635 * fns.c (hash_string): New function, taken from sxhash_string.
7636 Do not discard information about ASCII character case; this
7637 discarding is no longer needed.
7638 (sxhash-string): Use it. Change sig to match it. Caller changed.
7639 * lisp.h: Declare it.
7640 * lread.c (hash_string): Remove, since we now use fns.c's version.
7641 The fns.c version returns a wider integer if --with-wide-int is
7642 specified, so this should help the quality of the hashing a bit.
7644 * emacs.c: Integer overflow minor fix.
7645 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
7646 Define only if GNU_LINUX.
7647 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
7649 * dispnew.c: Integer signedness and overflow fixes.
7650 Remove unnecessary forward decls, that were a maintenance hassle.
7651 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
7652 All uses changed.
7653 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
7654 (scrolling_window): Use ptrdiff_t, not int, for byte count.
7655 (prepare_desired_row, line_draw_cost):
7656 Use int, not unsigned, where either works.
7657 (save_current_matrix, restore_current_matrix):
7658 Use ptrdiff_t, not size_t, where either works.
7659 (init_display): Check for overflow more accurately, and without
7660 relying on undefined behavior.
7662 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
7663 Remove, replacing with the new symbols in lisp.h. All uses changed.
7664 * fileio.c (make_temp_name):
7665 * filelock.c (lock_file_1, lock_file):
7666 * xdisp.c (message_dolog):
7667 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
7668 Use pMd etc. instead.
7669 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
7670 replacing the pWIDE etc. symbols removed from editfns.c.
7672 * keyboard.h (num_input_events): Now uintmax_t.
7673 This is (very slightly) less likely to mess up due to wraparound.
7674 All uses changed.
7676 * buffer.c: Integer signedness fixes.
7677 (alloc_buffer_text, enlarge_buffer_text):
7678 Use ptrdiff_t rather than size_t when either will do, as we prefer
7679 signed integers.
7681 * alloc.c: Integer signedness and overflow fixes.
7682 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
7683 (__malloc_size_t): Default to size_t, not to int.
7684 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
7685 (Fgarbage_collect, mark_object_loop_halt, mark_object):
7686 Prefer ptrdiff_t to size_t when either would do, as we prefer
7687 signed integers.
7688 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
7689 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
7690 Now const. Initialize with values that are in range even if char
7691 is signed.
7692 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
7693 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
7694 These functions do the right thing with sizes > 2**32.
7695 (check_depth): Now ptrdiff_t, not int.
7696 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
7697 Adjust to new way of storing sizes. Check for size overflow bugs
7698 in rest of code.
7699 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
7700 slightly wrong anyway, as it missed one instance of
7701 XMALLOC_OVERRUN_CHECK_OVERHEAD.
7702 (refill_memory_reserve): Omit needless cast to size_t.
7703 (mark_object_loop_halt): Mark as externally visible.
7705 * xselect.c: Integer signedness and overflow fixes.
7706 (Fx_register_dnd_atom, x_handle_dnd_message):
7707 Use ptrdiff_t, not size_t, since we prefer signed.
7708 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
7709 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
7710 x_dnd_atoms_size and x_dnd_atoms_length.
7712 * doprnt.c: Prefer signed to unsigned when either works.
7713 * eval.c (verror):
7714 * doprnt.c (doprnt):
7715 * lisp.h (doprnt):
7716 * xdisp.c (vmessage):
7717 Use ptrdiff_t, not size_t, when using or implementing doprnt,
7718 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
7719 prefer signed arithmetic to avoid comparison confusion.
7720 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
7721 but is a bit tricky.
7723 Assume freestanding C89 headers, string.h, stdlib.h.
7724 * data.c, doprnt.c, floatfns.c, print.c:
7725 Include float.h unconditionally.
7726 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
7727 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
7728 * regex.c: Likewise for stddef.h, string.h.
7729 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
7730 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
7731 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
7732 (STDC_HEADERS): Remove obsolete defines.
7733 * sysdep.c: Include limits.h unconditionally.
7735 Assume support for memcmp, memcpy, memmove, memset.
7736 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
7737 * regex.c (memcmp, memcpy):
7738 Remove; we assume C89 now.
7740 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
7741 (__malloc_safe_bcopy): Remove; no longer needed.
7743 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
7744 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
7745 well either way, and we prefer signed to unsigned.
7747 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
7749 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
7750 closes the connection while we're reading (bug#9182).
7752 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
7754 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
7755 are specified (Bug#9168).
7757 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
7759 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
7760 Found by GCC static checking and --with-wide-int on a 32-bit host.
7762 2011-07-25 Eli Zaretskii <eliz@gnu.org>
7764 * xdisp.c (compute_display_string_pos): Fix logic of caching
7765 previous display string position. Initialize cached_prev_pos to
7766 -1. Fixes slow-down at the beginning of a buffer.
7768 2011-07-24 Eli Zaretskii <eliz@gnu.org>
7770 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
7771 for attrs[LFACE_FONTSET_INDEX].
7773 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
7775 * xml.c (parse_region): Remove unused local
7776 that was recently introduced.
7778 2011-07-23 Eli Zaretskii <eliz@gnu.org>
7780 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
7781 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
7783 * xdisp.c (move_it_in_display_line_to): Record the best matching
7784 position for TO_CHARPOS while scanning the line, and restore it on
7785 exit if none of the characters scanned was an exact match.
7786 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
7787 when exact match is impossible due to invisible text, and the
7788 lines are truncated.
7790 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
7792 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
7793 for OSX >= 10.7.
7795 2011-07-22 Eli Zaretskii <eliz@gnu.org>
7797 Fix a significant slow-down of cursor motion with C-n, C-p,
7798 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
7799 auto-repeat under bidi redisplay in fontified buffers.
7800 * xdisp.c (compute_stop_pos_backwards): New function.
7801 (next_element_from_buffer): Call compute_stop_pos_backwards to
7802 find a suitable prev_stop when we find ourselves before
7803 base_level_stop.
7804 (reseat): Don't look for prev_stop, as that could mean a very long
7805 run.
7806 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
7807 <cached_disp_overlay_modiff>: Cache for last found display string
7808 position.
7809 (compute_display_string_pos): Return the cached position if asked
7810 about the same buffer in the same area of character positions, and
7811 the buffer wasn't changed since the time the display string
7812 position was cached.
7814 2011-07-22 Eli Zaretskii <eliz@gnu.org>
7816 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
7817 is an integer, which is important for empty lines. (Bug#9149)
7819 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
7821 * frame.c (Fmodify_frame_parameters): In tty case, update the
7822 default face if necessary (Bug#4238).
7824 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
7826 * editfns.c (Fstring_to_char): No need to explain what a character
7827 is in the docstring (Bug#6576).
7829 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
7831 * xml.c (parse_region): Make sure we always return a tree.
7833 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
7835 * xml.c (parse_region): If a document contains only comments,
7836 return that, too.
7838 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
7840 * xml.c (make_dom): Return comments, too.
7842 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
7844 Port to OpenBSD.
7845 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
7846 and the surrounding thread.
7847 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
7848 rather than fgets, and retry after EINTR. Otherwise, 'emacs
7849 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
7850 timer goes off.
7851 * s/openbsd.h (BROKEN_SIGIO): Define.
7852 * unexelf.c (unexec) [__OpenBSD__]:
7853 Don't update the .mdebug section of the Alpha COFF symbol table.
7855 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7857 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
7858 (bug#8460).
7860 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
7862 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
7863 This fixes some race conditions on the permissions of any newly
7864 created file.
7866 * alloc.c (valid_pointer_p): Use pipe, not open.
7867 This fixes some permissions issues when debugging.
7869 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
7870 If fchown fails to set both uid and gid, try to set just gid,
7871 as that is sometimes allowed. Adjust the file's mode to eliminate
7872 setuid or setgid bits that are inappropriate if fchown fails.
7874 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
7876 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
7877 to compare Lisp_Objects.
7878 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
7879 global_gnutls_log_level, don't mistake it for a Lisp_Object.
7880 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
7882 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
7884 * lread.c (read_integer): Unread even EOF character.
7885 (read1): Likewise. Properly record start position of symbol.
7887 * lread.c (read1): Read `#:' as empty uninterned symbol if no
7888 symbol character follows.
7890 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
7892 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
7893 This works around a problem with the previous change to Fcopy_file.
7894 Recent glibc declares fchown with __attribute__((warn_unused_result)),
7895 and without this change, GCC might complain about discarding
7896 fchown's return value.
7898 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
7900 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
7902 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
7904 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
7906 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
7908 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
7909 it's used from the C level.
7911 * process.c: Use the same condition for POLL_FOR_INPUT in both
7912 keyboard.c and process.c (bug#1858).
7914 2011-07-09 Lawrence Mitchell <wence@gmx.li>
7916 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
7917 (Fgnutls_boot): Use it.
7919 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
7921 * doc.c (Fsubstitute_command_keys): Revert last change.
7923 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
7925 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
7926 quotes the next character, and doesn't affect other longer
7927 sequences (bug#8935).
7929 * lread.c (syms_of_lread): Clarify that is isn't only
7930 `eval-buffer' and `eval-defun' that's affected by
7931 `lexical-binding' (bug#8460).
7933 2011-07-15 Eli Zaretskii <eliz@gnu.org>
7935 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
7936 bidi redisplay when a line includes both an image and is truncated.
7938 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
7940 Fix minor problems found by static checking.
7941 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
7942 (elsz): Now a signed constant, not a size_t var. We prefer signed
7943 types to unsigned, to avoid integer comparison confusion. Without
7944 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
7945 "cannot optimize loop, the loop counter may overflow", a symptom
7946 of the confusion.
7947 * indent.c (Fvertical_motion): Mark locals as initialized.
7948 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
7950 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
7952 * search.c (Fre_search_backward): Mention `case-fold-search' in
7953 all the re_search_* functions (bug#8138).
7955 * keyboard.c (Fopen_dribble_file): Document when the file is
7956 closed (bug#8056).
7958 2011-07-14 Eli Zaretskii <eliz@gnu.org>
7960 * bidi.c (bidi_dump_cached_states): Fix format of displaying
7961 bidi_cache_idx.
7963 Support bidi reordering of display and overlay strings.
7964 * xdisp.c (compute_display_string_pos)
7965 (compute_display_string_end): Accept additional argument STRING.
7966 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
7967 (reseat_to_string): Initialize bidi_it->string.s and
7968 bidi_it->string.schars.
7969 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
7970 NULL (avoids a crash in bidi_paragraph_init).
7971 Initialize itb.string.lstring.
7972 (init_iterator): Call bidi_init_it only of a valid
7973 buffer position was specified. Initialize paragraph_embedding to
7974 L2R.
7975 (reseat_to_string): Initialize the bidi iterator.
7976 (display_string): If we need to ignore text properties of
7977 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
7978 original value of -1 will not work with bidi.)
7979 (compute_display_string_pos): First arg is now struct
7980 `text_pos *'; all callers changed. Support display properties on
7981 Lisp strings.
7982 (compute_display_string_end): Support display properties on Lisp
7983 strings.
7984 (init_iterator, reseat_1, reseat_to_string): Initialize the
7985 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
7986 when iterating on a string not from display properties).
7987 (compute_display_string_pos, compute_display_string_end):
7988 Fix calculation of the object to scan. Fixes an error when using
7989 arrow keys.
7990 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
7991 base_level_stop; instead, set base_level_stop to BEGV.
7992 Fixes crashes in vertical-motion.
7993 (next_element_from_buffer): Improve commentary for when
7994 the iterator is before prev_stop.
7995 (init_iterator): Initialize bidi_p from the default value of
7996 bidi-display-reordering, not from buffer-local value. Use the
7997 buffer-local value only if initializing for buffer iteration.
7998 (handle_invisible_prop): Support invisible properties on strings
7999 that are being bidi-reordered.
8000 (set_iterator_to_next): Support bidi reordering of C strings and
8001 Lisp strings.
8002 (next_element_from_string): Support bidi reordering of Lisp
8003 strings.
8004 (handle_stop_backwards): Support Lisp strings as well.
8005 (display_string): Support display of R2L glyph rows.
8006 Use IT_STRING_CHARPOS when displaying from a Lisp string.
8007 (init_iterator): Don't initialize it->bidi_p for strings
8008 here.
8009 (reseat_to_string): Initialize it->bidi_p for strings here.
8010 (next_element_from_string, next_element_from_c_string)
8011 (next_element_from_buffer): Add xassert's for correspondence
8012 between IT's object being iterated and it->bidi_it.string
8013 structure.
8014 (face_before_or_after_it_pos): Support bidi iteration.
8015 (next_element_from_c_string): Handle the case of the first string
8016 character that is not the first one in the visual order.
8017 (get_visually_first_element): New function, refactored from common
8018 parts of next_element_from_buffer, next_element_from_string, and
8019 next_element_from_c_string.
8020 (tool_bar_lines_needed, redisplay_tool_bar)
8021 (display_menu_bar): Force left-to-right direction. Add a FIXME
8022 comment for making that be controlled by a user option.
8023 (push_it, pop_it): Save and restore the state of the
8024 bidi iterator. Save and restore the bidi_p flag.
8025 (pop_it): Iterate out of display property for string iteration as
8026 well.
8027 (iterate_out_of_display_property): Support iteration over strings.
8028 (handle_single_display_spec): Set up it->bidi_it for iteration
8029 over a display string, and call bidi_init_it.
8030 (handle_single_display_spec, next_overlay_string)
8031 (get_overlay_strings_1, push_display_prop): Set up the bidi
8032 iterator for displaying display or overlay strings.
8033 (forward_to_next_line_start): Don't use the shortcut if

8039 and we are bidi-iterating, don't decrement the iterator position;
8040 instead, set the first_elt flag in the bidi iterator, to produce
8041 the same effect.

8078 (move_it_in_display_line_to): If iterator ended up at
8079 EOL, but we never saw any buffer positions smaller than
8080 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
8081 motion in bidi-reordered lines.
8082 (move_it_in_display_line_to): Record prev_method and prev_pos
8083 immediately before the call to set_iterator_to_next. Fixes cursor

8474 This isn't true in general, and it's particularly not true
8475 if Emacs is configured with --with-wide-int.
8476 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
8477 New macros, used in the buffer.c change.

8509 Add comment.
8511 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
8513 Random fixes. E.g., (random) never returned negative values.
8514 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
8515 subseconds part to the entropy, as that's a bit more random.
8516 Prefer signed to unsigned, since the signedness doesn't matter and
8517 in general we prefer signed. When given a limit, use a
8518 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
8519 latter isn't right if USE_2_TAGS_FOR_INTS.
8520 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
8521 not 0..VALMASK. Don't discard "excess" bits that random () returns.
8523 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
8525 * textprop.c (text_property_stickiness):
8526 Obey Vtext_property_default_nonsticky.

8531 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
8533 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
8534 This is more efficient than Ffile_directory_p and avoids a minor race.
8536 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
8538 * buffer.c (Foverlay_put): Say what the return value is
8539 (bug#7835).
8541 * fileio.c (barf_or_query_if_file_exists): Check first if the file
8542 is a directory before asking whether to use the file name
8543 (bug#7564).
8544 (barf_or_query_if_file_exists): Make the "File is a directory"
8545 error be more correct.
8547 * fns.c (Frequire): Remove the mention of the .gz files, since
8548 that's installation-specific, but keep the mention of
8549 `get-load-suffixes'.
8551 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
8553 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.
8554 Report string overflow if the output is too long.
8556 2011-07-04 Juanma Barranquero <lekktu@gmail.com>
8558 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
8559 (syms_of_gnutls): Remove duplicate DEFSYM for
8560 Qgnutls_bootprop_verify_hostname_error, an error for
8561 Qgnutls_bootprop_verify_error (which is no longer used).
8563 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
8564 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
8565 Also (re)move comments that are misplaced or no longer relevant.
8567 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
8569 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).
8571 2011-07-03 Chong Yidong <cyd@stupidchicken.com>
8573 * xfaces.c (Finternal_merge_in_global_face): Modify the foreground
8574 and background color parameters if they have been changed.

8594 * lread.c (syms_of_lread): Mention single symbols defined by
8595 `defvar' or `defconst' (bug#7154).
8597 * fns.c (Frequire): Mention .el.gz files (bug#7314).
8598 (Frequire): Mention get-load-suffixes.

8628 (syms_of_keymap): Defsubr make-composed-keymap.
8629 * keyboard.c (menu_bar_items): Use map_keymap_canonical.
8630 (parse_menu_item): Trivial simplification.
8632 2011-07-01 Glenn Morris <rgm@gnu.org>

8660 * process.c: Add defined (HAVE_GSETTINGS) for xgselect.h
8661 (wait_reading_process_output): Add defined (HAVE_GSETTINGS) for
8662 xg_select.
8664 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
8666 * eval.c (struct backtrace): Simplify and port the data structure.
8667 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
8668 signed bit field, as this assumption is not portable and it makes
8669 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
8670 "char debug_on_exit : 1" as this is not portable either; instead,
8671 use the portable "unsigned int debug_on_exit : 1". Remove unused
8672 member evalargs. Remove obsolete comments about cc bombing out.
8674 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
8676 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

8687 (init_gsettings): New function.
8688 (xsettings_initialize): Call init_gsettings.
8689 (syms_of_xsettings): Initialize gsettings_client, gsettings_obj
8690 to NULL.
8692 * Makefile.in (SETTINGS_CFLAGS, SETTINGS_LIBS): Rename from
8693 GCONF_CFLAGS/LIBS.

8709 clearly which files are directly included by each source file,
8710 and not through other includes.
8712 2011-06-27 Martin Rudalics <rudalics@gmx.at>
8714 * buffer.c (Qclone_number): Declare static and DEFSYM it.
8715 (sort_overlays, overlay_strings): When an overlay's clone number
8716 matches the window's clone number process the overlay even if
8717 the overlay's window property doesn't match the current window.
8719 * window.c (Fwindow_vchild): Rename to Fwindow_top_child.
8720 (Fwindow_hchild): Rename to Fwindow_left_child.
8721 (Fwindow_next): Rename to Fwindow_next_sibling.
8722 (Fwindow_prev): Rename to Fwindow_prev_sibling.
8723 (resize_window_check): Rename to window_resize_check.
8724 (resize_window_apply): Rename to window_resize_apply.
8725 (Fresize_window_apply): Rename to Fwindow_resize_apply.

8742 (emacs_fixed_new): Set priv->f to argument.
8743 (emacs_fixed_get_preferred_width)
8744 (emacs_fixed_get_preferred_height): Use min_width/height from
8745 frames size_hint to set minimum and natural (Bug#8919).
8746 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
8747 and use min_width/height from frames size_hint to set
8748 min_width/height (Bug#8919).
8750 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.
8751 (x_wm_set_size_hint): Remove call to emacs_fixed_set_min_size.

8766 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
8768 Use gnulib's dup2 module instead of rolling our own.
8769 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

8838 Integer and buffer overflow fixes (Bug#8873).
8840 * print.c (printchar, strout): Check for string overflow.

8842 Don't set size unless allocation succeeds.
8844 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
8845 for sizes. Check for string overflow more accurately.

8856 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
8858 * lread.c: Integer overflow fixes.
8859 (read_integer): Radix is now EMACS_INT, not int,
8860 to improve quality of diagnostics for out-of-range radices.
8861 Calculate buffer size correctly for out-of-range radices.
8862 (read1): Check for integer overflow in radices, and in
8863 read-circle numbers.
8864 (read_escape): Avoid int overflow.
8865 (Fload, openp, read_buffer_size, read1)
8866 (substitute_object_recurse, read_vector, read_list, map_obarray):
8867 Use ptrdiff_t, not int, for sizes.

8887 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
8889 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
8890 The following patches are for when GLYPH_DEBUG && !XASSERT.
8891 * dispextern.h (trace_redisplay_p, dump_glyph_string):
8892 * dispnew.c (flush_stdout):
8893 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
8894 Mark as externally visible.
8895 * dispnew.c (check_window_matrix_pointers): Now static.
8896 * dispnew.c (window_to_frame_vpos):
8897 * xfns.c (unwind_create_frame):
8898 * xterm.c (x_check_font): Remove unused local.
8899 * scroll.c (CHECK_BOUNDS):
8900 * xfaces.c (cache_fache): Rename local to avoid shadowing.
8901 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
8902 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
8903 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
8904 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
8905 Now static.
8906 (debug_method_add): Use va_list and vsprintf rather than relying
8907 on undefined behavior with wrong number of arguments.
8908 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
8909 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
8910 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
8911 since we're not interested in debugging glyphs with old libraries.
8912 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
8913 GCC 4.6.0's static checking.
8915 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
8917 Integer overflow and signedness fixes (Bug#8873).
8918 A few related buffer overrun fixes, too.

8925 (x_create_bitmap_from_data, x_create_bitmap_from_file)
8926 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
8927 (x_create_bitmap_from_xpm_data):
8928 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
8929 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
8930 (.bitmaps_last):
8931 * xfaces.c (load_pixmap):
8932 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
8933 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
8934 (.bitmaps_last, struct x_output.icon_bitmap):
8935 Use ptrdiff_t, not int, for bitmap indexes.
8936 (x_allocate_bitmap_record): Check for size overflow.
8937 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
8939 Use ptrdiff_t, not int, for overlay counts.
8940 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
8941 * editfns.c (overlays_around, get_pos_property):
8942 * textprop.c (get_char_property_and_overlay):
8943 * xdisp.c (next_overlay_change, note_mouse_highlight):
8944 * xfaces.c (face_at_buffer_position):
8945 * buffer.c (OVERLAY_COUNT_MAX): New macro.
8946 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
8947 (Fnext_overlay_change, Fprevious_overlay_change)
8948 (mouse_face_overlay_overlaps, Foverlays_in):
8949 Use ptrdiff_t, not int, for sizes.
8950 (overlays_at, overlays_in): Check for size-calculation overflow.
8952 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
8954 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
8955 (x_session_initialize): Do not assume string length fits in int.
8957 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
8958 This is unlikely, but can occur if DPI is outlandish.
8960 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
8961 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
8963 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
8964 * xrdb.c (magic_file_p, search_magic_path):
8965 Omit last arg SUFFIX; it was always 0. All callers changed.
8966 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
8968 * xfont.c (xfont_match): Avoid need for strlen.
8970 * xfns.c: Don't assume strlen fits in int.
8971 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
8973 * xdisp.c (message_log_check_duplicate): Return intmax_t,
8974 not unsigned long, as we prefer signed integers. All callers changed.
8975 Detect integer overflow in repeat count.
8976 (message_dolog): Don't assume print length fits in 39 bytes.
8977 (display_mode_element): Don't assume strlen fits in int.
8979 * termcap.c: Don't assume sizes fit in int and never overflow.
8980 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
8981 (gobble_line): Check for size-calculation overflow.
8983 * minibuf.c (Fread_buffer):
8984 * lread.c (intern, intern_c_string):
8985 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
8986 Don't assume string length fits in int.
8988 * keyboard.c (parse_tool_bar_item):
8989 * gtkutil.c (style_changed_cb): Avoid need for strlen.
8991 * font.c: Don't assume string length fits in int.
8992 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
8993 Use ptrdiff_t, not int.
8994 (font_intern_prop): Don't assume string length fits in int.
8995 Don't assume integer property fits in fixnum.
8996 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
8998 * filelock.c: Fix some buffer overrun and integer overflow issues.
8999 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
9000 Reformulate so as not to need the command string.
9001 Invoke gzip -cd rather than gunzip, as it's more portable.
9002 (lock_info_type, lock_file_1, lock_file):
9003 Don't assume pid_t and time_t fit in unsigned long.
9004 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
9005 (current_lock_owner): Prefer signed type for sizes.
9006 Use memcpy, not strncpy, where memcpy is what is really wanted.
9007 Don't assume (via atoi) that time_t and pid_t fit in int.
9008 Check for time_t and/or pid_t out of range, e.g., via a network share.
9009 Don't alloca where an auto var works fine.
9011 * fileio.c: Fix some integer overflow issues.
9012 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
9013 Don't assume string length fits in int.
9014 (directory_file_name): Don't assume string length fits in long.
9015 (make_temp_name): Don't assume pid fits in int, or that its print
9016 length is less than 20.
9018 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
9020 * coding.c (make_subsidiaries): Don't assume string length fits in int.
9022 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
9024 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
9025 We prefer signed integers, even for size calculations.
9027 * emacs.c: Don't assume string length fits in 'int'.
9028 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
9029 (main): Don't invoke strlen when not needed.
9031 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
9032 (XD_DEBUG_MESSAGE): Don't waste a byte.
9034 * callproc.c (getenv_internal_1, getenv_internal)
9035 (Fgetenv_internal):
9036 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
9038 * lread.c (invalid_syntax): Omit length argument.
9039 All uses changed. This doesn't fix a bug, but it simplifies the
9040 code away from its former Hollerith-constant appearance, and it's
9041 one less 'int' to worry about when looking at integer-overflow issues.
9042 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
9044 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
9045 This didn't break anything, but it didn't help either.
9046 It's confusing to put a bogus integer in a place where the actual
9047 value does not matter.
9048 (LIST_END_P): Remove unused macro and its bogus comment.
9049 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
9051 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
9052 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
9053 implementation.
9054 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
9055 We prefer signed types, and the value cannot exceed the EMACS_INT
9056 range anyway (because otherwise the length would not be representable).
9057 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
9058 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
9059 This avoids a GCC warning when WIDE_EMACS_INT.
9061 * indent.c (sane_tab_width): New function.
9062 (current_column, scan_for_column, Findent_to, position_indentation)
9063 (compute_motion): Use it. This is just for clarity.
9064 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
9066 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
9068 * lisp.h (lint_assume): New macro.
9069 * composite.c (composition_gstring_put_cache):
9070 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
9072 * editfns.c, insdel.c:
9073 Omit unnecessary forward decls, to simplify future changes.
9075 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
9077 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
9079 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
9080 Use much-faster test for byte-length change.
9081 Don't assume string byte-length fits in 'int'.
9082 Check that character arg fits in 'int'.
9083 (mapcar1): Declare byte as byte, for clarity.
9085 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
9087 * fns.c (concat): Catch string overflow earlier.
9088 Do not rely on integer wraparound.
9090 * dispextern.h (struct it.overlay_strings_charpos)
9091 (struct it.selective): Now EMACS_INT, not int.
9092 * xdisp.c (forward_to_next_line_start)
9093 (back_to_previous_visible_line_start)
9094 (reseat_at_next_visible_line_start, next_element_from_buffer):
9095 Don't arbitrarily truncate the value of 'selective' to int.
9097 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
9099 * composite.c: Don't truncate sizes to 'int'.
9100 (composition_gstring_p, composition_reseat_it)
9101 (composition_adjust_point): Use EMACS_INT, not int.
9102 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
9103 not EMACS_UINT, for indexes.
9105 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
9107 * buffer.c: Include <verify.h>.
9108 (struct sortvec.priority, struct sortstr.priority):
9109 Now EMACS_INT, not int.
9110 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
9111 (struct sortstr.size, record_overlay_string)
9112 (struct sortstrlist.size, struct sortlist.used):
9113 Don't truncate size to int.
9114 (record_overlay_string): Check for size-calculation overflow.
9115 (init_buffer_once): Check at compile-time, not run-time.
9117 2011-06-22 Jim Meyering <meyering@redhat.com>
9119 Don't leak an XBM-image-sized buffer
9120 * image.c (xbm_load): Free the image buffer after using it.
9122 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
9124 Port to Sun C.
9125 * composite.c (find_automatic_composition): Omit needless 'return 0;'
9126 that Sun C diagnosed.
9127 * fns.c (secure_hash): Fix pointer signedness issue.
9128 * intervals.c (static_offset_intervals): New function.
9129 (offset_intervals): Use it.
9131 2011-06-21 Leo Liu <sdl.web@gmail.com>
9133 * deps.mk (fns.o):
9134 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
9135 sha512.h.
9137 * fns.c (secure_hash): Rename from crypto_hash_function and change
9138 the first arg to accept symbols.
9139 (Fsecure_hash): New primitive.
9140 (syms_of_fns): New symbols.
9142 2011-06-20 Deniz Dogan <deniz@dogan.se>
9144 * process.c (Fset_process_buffer): Clarify return value in
9145 docstring.
9147 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
9149 * dispnew.c (add_window_display_history): Use BVAR.
9151 * xdisp.c (debug_method_add): Use BVAR.
9152 (check_window_end, dump_glyph_matrix, dump_glyph)
9153 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
9155 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
9156 Likewise.
9158 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
9159 check till after the cache is created in init_frame_faces.
9161 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
9163 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
9165 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
9167 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
9168 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
9169 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
9171 Improve buffer-overflow checking (Bug#8873).
9172 * fileio.c (Finsert_file_contents):
9173 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
9174 Remove the old (too-loose) buffer overflow checks.
9175 They weren't needed, since make_gap checks for buffer overflow.
9176 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
9177 The old code merely checked for Emacs fixnum overflow, and relied
9178 on undefined (wraparound) behavior. The new code avoids undefined
9179 behavior, and also checks for ptrdiff_t and/or size_t overflow.
9181 * editfns.c (Finsert_char): Don't dump core with very negative counts.
9182 Tune. Don't use wider integers than needed. Don't use alloca.
9183 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
9185 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
9187 * insdel.c, lisp.h (buffer_overflow): New function.
9188 (insert_from_buffer_1, replace_range, replace_range_2):
9189 * insdel.c (make_gap_larger):
9190 * editfns.c (Finsert_char):
9191 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
9193 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
9195 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
9197 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
9199 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
9200 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
9202 * fileio.c: Don't assume EMACS_INT fits in off_t.
9203 (emacs_lseek): New static function.
9204 (Finsert_file_contents, Fwrite_region): Use it.
9205 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
9207 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
9209 * fns.c: Don't overflow int when computing a list length.
9210 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
9211 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
9212 truncation on 64-bit hosts. Check for QUIT every
9213 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
9214 faster and is responsive enough.
9215 (Flength): Report an error instead of overflowing an integer.
9216 (Fsafe_length): Return a float if the value is not representable
9217 as a fixnum. This shouldn't happen except in contrived situations.
9218 (Fnthcdr, Fsort): Don't assume list length fits in int.
9219 (Fcopy_sequence): Don't assume vector length fits in int.
9221 * alloc.c: Check that resized vectors' lengths fit in fixnums.
9222 (header_size, word_size): New constants.
9223 (allocate_vectorlike): Don't check size overflow here.
9224 (allocate_vector): Check it here instead, since this is the only
9225 caller of allocate_vectorlike that could cause overflow.
9226 Check that the new vector's length is representable as a fixnum.
9228 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
9229 The previous code was bogus. For example, next_almost_prime (32)
9230 returned 39, which is undesirable as it is a multiple of 3; and
9231 next_almost_prime (24) returned 25, which is a multiple of 5 so
9232 why was the code bothering to check for multiples of 7?
9234 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
9236 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
9238 Variadic C functions now count arguments with ptrdiff_t.
9239 This partly undoes my 2011-03-30 change, which replaced int with size_t.
9240 Back then I didn't know that the Emacs coding style prefers signed int.
9241 Also, in the meantime I found a few more instances where arguments
9242 were being counted with int, which may truncate counts on 64-bit
9243 machines, or EMACS_INT, which may be unnecessarily wide.
9244 * lisp.h (struct Lisp_Subr.function.aMANY)
9245 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
9246 Arg counts are now ptrdiff_t, not size_t.
9247 All variadic functions and their callers changed accordingly.
9248 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
9249 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
9250 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
9251 * callint.c (Fcall_interactively): Check arg count for overflow,
9252 to avoid potential buffer overrun. Use signed char, not 'int',
9253 for 'varies' array, so that we needn't bother to check its size
9254 calculation for overflow.
9255 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
9256 * eval.c (apply_lambda):
9257 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
9258 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
9259 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
9261 * callint.c (Fcall_interactively): Don't use index var as event count.
9263 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
9264 * mem-limits.h (SIZE): Remove; no longer used.
9266 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
9268 Remove unnecessary casts.
9269 * xterm.c (x_term_init):
9270 * xfns.c (x_set_border_pixel):
9271 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
9272 These aren't needed now that we assume ANSI C.
9274 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
9275 It's more likely to cause problems (due to unsigned overflow)
9276 than to cure them.
9278 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
9280 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
9282 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
9284 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
9286 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
9288 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
9290 GLYPH_CODE_FACE returns EMACS_INT, not int.
9291 * dispextern.h (merge_faces):
9292 * xfaces.c (merge_faces):
9293 * xdisp.c (get_next_display_element, next_element_from_display_vector):
9294 Don't assume EMACS_INT fits in int.
9296 * character.h (CHAR_VALID_P): Remove unused parameter.
9297 * fontset.c, lisp.h, xdisp.c: All uses changed.
9299 * editfns.c (Ftranslate_region_internal): Omit redundant test.
9301 * fns.c (concat): Minor tuning based on overflow analysis.
9302 This doesn't fix any bugs. Use int to hold character, instead
9303 of constantly refetching from Emacs object. Use XFASTINT, not
9304 XINT, for value known to be a character. Don't bother comparing
9305 a single byte to 0400, as it's always less.
9307 * floatfns.c (Fexpt):
9308 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
9310 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
9311 for characters.
9313 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
9315 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
9316 Without this fix, on a 64-bit host (aset S 0 4294967386) would
9317 incorrectly succeed when S was a string, because 4294967386 was
9318 truncated before it was used.
9320 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
9321 Otherwise, an out-of-range integer could cause undefined behavior
9322 on a 64-bit host.
9324 * composite.c: Use int, not EMACS_INT, for characters.
9325 (fill_gstring_body, composition_compute_stop_pos): Use int, not
9326 EMACS_INT, for values that are known to be in character range.
9327 This doesn't fix any bugs but is the usual style inside Emacs and
9328 may generate better code on 32-bit machines.
9330 Make sure a 64-bit char is never passed to ENCODE_CHAR.
9331 This is for reasons similar to the recent CHAR_STRING fix.
9332 * charset.c (Fencode_char): Check that character arg is actually
9333 a character. Pass an int to ENCODE_CHAR.
9334 * charset.h (ENCODE_CHAR): Verify that the character argument is no
9335 wider than 'int', as a compile-time check to prevent future regressions
9336 in this area.
9338 * character.c (char_string): Remove unnecessary casts.
9340 Make sure a 64-bit char is never passed to CHAR_STRING.
9341 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
9342 by silently ignoring the top 32 bits, allowing some values
9343 that were far too large to be valid characters.
9344 * character.h: Include <verify.h>.
9345 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
9346 arguments are no wider than unsigned, as a compile-time check
9347 to prevent future regressions in this area.
9348 * data.c (Faset):
9349 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
9350 (Fsubst_char_in_region):
9351 * fns.c (concat):
9352 * xdisp.c (decode_mode_spec_coding):
9353 Adjust to CHAR_STRING's new requirement.
9354 * editfns.c (Finsert_char, Fsubst_char_in_region):
9355 * fns.c (concat): Check that character args are actually
9356 characters. Without this test, these functions did the wrong
9357 thing with wildly out-of-range values on 64-bit hosts.
9359 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
9360 These casts should not be needed on 32-bit hosts, either.
9361 * keyboard.c (read_char):
9362 * lread.c (Fload): Remove casts to unsigned.
9364 * lisp.h (UNSIGNED_CMP): New macro.
9365 This fixes comparison bugs on 64-bit hosts.
9366 (ASCII_CHAR_P): Use it.
9367 * casefiddle.c (casify_object):
9368 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
9369 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
9370 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
9371 * dispextern.h (FACE_FROM_ID):
9372 * keyboard.c (read_char): Use UNSIGNED_CMP.
9374 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
9375 not to EMACS_INT, to avoid GCC warning.
9377 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
9379 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.

9384 Use EMACS_INT for count, not int.
9385 (advance_to_char_boundary): Return EMACS_INT, not int.

9404 (total_free_floats, total_floats, total_free_intervals)
9405 (total_intervals, total_strings, total_free_strings):
9406 Now EMACS_INT, not int. All uses changed.

9408 integer overflow is less likely to be a problem. Check for overflow
9409 when converting back to an integer.
9410 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
9411 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
9412 These were 'int' variables that could overflow on 64-bit hosts;
9413 they were never used, so remove them instead of repairing them.

9422 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
9423 when a (possibly-narrower) signed value would do just as well.
9424 We prefer using signed arithmetic, to avoid comparison confusion.
9426 * alloc.c: Catch some string size overflows that we were missing.
9427 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
9428 for convenience in STRING_BYTES_MAX.
9429 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
9430 The definition here is exact; the one in lisp.h was approximate.
9431 (allocate_string_data): Check for string overflow. This catches
9432 some instances we weren't catching before. Also, it catches
9433 size_t overflow on (unusual) hosts where SIZE_MAX <= min
9434 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
9435 and ptrdiff_t and EMACS_INT are both 64 bits.
9437 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
9438 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
9439 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
9441 * character.c (string_escape_byte8): Fix nbytes/nchars typo.

9943 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
9944 Do not assume that spare memory exists; that assumption is valid
9945 only if SYSTEM_MALLOC.
9946 (LARGE_REQUEST): New macro, so that the issue of large requests

10016 instead of using explicit *_CHAR codes.
10017 (bidi_resolve_explicit, bidi_resolve_weak):

10028 were just reseat()'ed to a new position.
10030 * xdisp.c (set_cursor_from_row): Set start and stop points
10031 according to the row's direction when priming the loop that looks
10032 for the glyph on which to display cursor.
10033 (single_display_spec_intangible_p): Function deleted.
10034 (display_prop_intangible_p): Reimplement to call
10035 handle_display_spec instead of single_display_spec_intangible_p.
10036 Accept 3 additional arguments needed by handle_display_spec.
10037 This fixes incorrect cursor motion across display property with complex
10038 values: lists, `(when COND...)' forms, etc.

10047 value of a `display' property is a "replacing spec".
10048 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
10049 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

10052 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
10053 frame_window_p members of struct bidi_it.
10054 (compute_display_string_pos, compute_display_string_end):

10060 * keyboard.c (adjust_point_for_property): Adjust the call to
10061 display_prop_intangible_p to its new signature.
10063 * dispextern.h (struct bidi_it): New member frame_window_p.

10077 All callers changed. (Bug#8762)
10079 * gnutls.c: Use Emacs's memory allocators.
10080 Without this change, the gnutls library would invoke malloc etc.
10081 directly, which causes problems on non-SYNC_INPUT hosts, and which
10082 runs afoul of improving memory_full behavior. (Bug#8761)
10083 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
10084 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
10085 xfree instead of the default malloc, realloc, free.
10086 (Fgnutls_boot): No need to check for memory allocation failure,
10087 since xmalloc does that for us.
10089 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

10113 * ccl.c (ccl_driver):
10114 Check for overflow when converting EMACS_INT to int.

10116 need to be updated by these changes.
10117 * fns.c (make_hash_table, maybe_resize_hash_table):
10118 Check for integer overflow with large hash tables.
10119 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
10120 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
10121 (SXHASH_REDUCE): New macro.
10122 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
10123 Use it instead of discarding useful hash info with large hash values.
10124 (sxhash_float): New function.
10125 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
10126 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
10127 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
10128 Rewrite to use FIXNUM_BITS, as this simplifies things.
10129 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
10130 Adjust signatures to match updated version of code.
10131 (consing_since_gc): Now EMACS_INT, since a single hash table can
10132 use more than INT_MAX bytes.

10181 Make it possible to run ./temacs.
10183 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,

10247 variables to unsigned, to avoid sign-extension bugs. For example,
10248 without this change, (md5 "truc") would evaluate to
10249 45723a2aff78ff4fff7fff1114760e62 rather than the expected
10250 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
10251 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
10253 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10255 Integer overflow fixes.
10257 * dbusbind.c: Serial number integer overflow fixes.
10258 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
10259 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
10260 to hold a serial number that is too large for a fixnum.
10261 (Fdbus_method_return_internal, Fdbus_method_error_internal):
10262 Check for serial numbers out of range. Decode any serial number
10263 that was so large that it became a float. (Bug#8722)
10265 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
10266 (Fdbus_call_method, Fdbus_call_method_asynchronously):
10267 Use XFASTINT rather than XUINT when numbers are nonnegative.
10268 (xd_append_arg, Fdbus_method_return_internal):
10269 (Fdbus_method_error_internal): Likewise. Also, for unsigned
10270 arguments, check that Lisp number is nonnegative, rather than
10271 silently wrapping negative numbers around. (Bug#8722)
10272 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
10273 (Bug#8722)
10275 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
10277 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
10279 ccl: Add integer overflow checks.
10280 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
10281 (IN_INT_RANGE): New macros.
10282 (ccl_driver): Use them to check for integer overflow when
10283 decoding a CCL program. Many of the new checks are whether XINT (x)
10284 fits in int; it doesn't always, on 64-bit hosts. The new version
10285 doesn't catch all possible integer overflows, but it's an
10286 improvement. (Bug#8719)
10288 * alloc.c (make_event_array): Use XINT, not XUINT.
10289 There's no need for unsigned here.
10291 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
10292 This follows up to the 2011-05-06 change that substituted uintptr_t
10293 for EMACS_INT. This case wasn't caught back then.
10295 Rework Fformat to avoid integer overflow issues.
10296 * editfns.c: Include <float.h> unconditionally, as it's everywhere
10297 now (part of C89). Include <verify.h>.
10298 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
10299 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
10300 (Fformat): Avoid the prepass trying to compute sizes; it was only
10301 approximate and thus did not catch overflow reliably. Instead, walk
10302 through the format just once, formatting and computing sizes as we go,
10303 checking for integer overflow at every step, and allocating a larger
10304 buffer as needed. Keep track separately whether the format is
10305 multibyte. Keep only the most-recently calculated precision, rather
10306 than them all. Record whether each argument has been converted to
10307 string. Use EMACS_INT, not int, for byte and char and arg counts.
10308 Support field widths and precisions larger than INT_MAX. Avoid
10309 sprintf's undefined behavior with conversion specifications such as %#d
10310 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
10311 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
10312 formatting out-of-range floating point numbers with int
10313 formats. (Bug#8668)
10315 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
10317 * data.c: Avoid integer truncation in expressions involving floats.
10318 * data.c: Include <intprops.h>.
10319 (arith_driver): When there's an integer overflow in an expression
10320 involving floating point, convert the integers to floating point
10321 so that the resulting value does not suffer from catastrophic
10322 integer truncation. For example, on a 64-bit host (* 4
10323 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
10324 Do not rely on undefined behavior after integer overflow.
10326 merge count_size_as_multibyte, parse_str_to_multibyte
10327 * character.c, character.h (count_size_as_multibyte):
10328 Rename from parse_str_to_multibyte; all uses changed.
10329 Check for integer overflow.
10330 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
10331 since it's now a duplicate of the other. This is more of
10332 a character than a buffer op, so better that it's in character.c.
10333 * fns.c, print.c: Adjust to above changes.
10335 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
10337 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
10339 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10341 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10342 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
10343 (x_clipboard_manager_save): Now static.
10344 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
10346 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10347 (crypto_hash_function): Now static.
10348 Fix pointer signedness problems. Avoid unnecessary initializations.
10350 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
10352 * termhooks.h (Vselection_alist): Make it terminal-local.
10354 * terminal.c (create_terminal): Initialize it.
10356 * xselect.c: Support for clipboard managers.
10357 (Vselection_alist): Move to termhooks.h as terminal-local var.
10358 (LOCAL_SELECTION): New macro.
10359 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
10360 (symbol_to_x_atom): Remove gratuitous arg.
10361 (x_handle_selection_request, lisp_data_to_selection_data)
10362 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
10363 (x_own_selection, x_get_local_selection, x_convert_selection):
10364 New arg, specifying work frame. Use terminal-local Vselection_alist.
10365 (some_frame_on_display): Delete unused function.
10366 (Fx_own_selection_internal, Fx_get_selection_internal)
10367 (Fx_disown_selection_internal, Fx_selection_owner_p)
10368 (Fx_selection_exists_p): New optional frame arg.
10369 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
10370 (x_handle_selection_clear): Don't treat other terminals with the
10371 same keyboard specially. Use the terminal-local Vselection_alist.
10372 (x_clear_frame_selections): Use Frun_hook_with_args.
10374 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
10376 * xterm.h: Add support for those atoms.
10378 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
10380 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
10381 (converted_selections, conversion_fail_tag): New global variables.
10382 (x_selection_request_lisp_error): Free the above.
10383 (x_get_local_selection): Remove unnecessary code.
10384 (x_reply_selection_request): Args changed; handle arbitrary array
10385 of converted selections stored in converted_selections.
10386 Separate the XChangeProperty and SelectionNotify steps.
10387 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
10388 (x_convert_selection): New function.
10389 (x_handle_selection_event): Simplify.
10390 (x_get_foreign_selection): Don't ignore incoming requests while
10391 waiting for an answer; this will fail when we implement
10392 SAVE_TARGETS, and seems unnecessary anyway.
10393 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
10394 (Vx_sent_selection_functions): Doc fix.
10396 2011-05-26 Leo Liu <sdl.web@gmail.com>
10398 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
10400 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10402 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
10404 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
10405 for fringe update if it has periodic bitmap.
10406 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
10407 and fringe_bitmap_periodic_p.
10409 * fringe.c (get_fringe_bitmap_data): New function.
10410 (draw_fringe_bitmap_1, update_window_fringes): Use it.
10411 (update_window_fringes): Record periodicity of fringe bitmap in glyph
10412 row. Mark glyph row for fringe update if periodicity changed.
10414 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
10415 for fringe update unless it has periodic bitmap.
10417 2011-05-25 Kenichi Handa <handa@m17n.org>
10419 * xdisp.c (get_next_display_element): Set correct it->face_id for
10420 a static composition.
10422 2011-05-24 Leo Liu <sdl.web@gmail.com>
10424 * deps.mk (fns.o):
10425 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
10427 * fns.c (crypto_hash_function, Fsha1): New function.
10428 (Fmd5): Use crypto_hash_function.
10429 (syms_of_fns): Add Ssha1.
10431 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
10433 * gnutls.c: Remove unused macros.
10434 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
10435 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
10436 Remove macros that are defined and never used.
10437 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
10439 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10441 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
10442 (Fx_get_selection_internal): Minor cleanup.
10443 (Fx_own_selection_internal): Rename arguments for consistency with
10444 select.el.
10446 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
10448 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
10450 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10452 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
10454 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10456 * dispnew.c (scrolling_window): Don't exclude the case that the
10457 last enabled row in the desired matrix touches the bottom boundary.
10459 2011-05-21 Glenn Morris <rgm@gnu.org>
10461 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
10462 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
10463 and add some more files.
10465 2011-05-20 Eli Zaretskii <eliz@gnu.org>
10467 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
10468 report_file_error introduced by the change from 2011-05-07.
10470 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
10472 * systime.h (Time): Define only if emacs is defined.
10473 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
10474 where the include path doesn't have X11/X.h by default. See
10475 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
10477 2011-05-20 Kenichi Handa <handa@m17n.org>
10479 * composite.c (find_automatic_composition): Fix previous change.
10481 2011-05-20 Glenn Morris <rgm@gnu.org>
10483 * lisp.mk: New file, split from Makefile.in.
10484 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
10485 (shortlisp): Remove.
10486 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
10488 2011-05-19 Glenn Morris <rgm@gnu.org>
10490 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
10491 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
10492 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
10493 (lisp): Set the order to that of loadup.el.
10494 (shortlisp): Make it a copy of $lisp.
10495 (SOME_MACHINE_LISP): Remove.
10496 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
10497 Use just $shortlisp, not $SOME_MACHINE_LISP too.
10499 2011-05-18 Kenichi Handa <handa@m17n.org>
10501 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
10502 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
10503 (find_automatic_composition): Mostly rewrite for efficiency.
10505 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
10507 * makefile.w32-in: Update dependencies.
10509 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
10511 * menu.c: Include limits.h (fixes the MS-Windows build broken by
10512 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
10514 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
10516 Fix some integer overflow issues, such as string length overflow.
10518 * insdel.c (count_size_as_multibyte): Check for string overflow.
10520 * character.c (lisp_string_width): Check for string overflow.
10521 Use EMACS_INT, not int, for string indexes and lengths; in
10522 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
10523 the resulting string length overflows an EMACS_INT; instead,
10524 report a string overflow if no precision given. When checking for
10525 precision exhaustion, use a check that cannot possibly have
10526 integer overflow. (Bug#8675)
10527 * character.h (lisp_string_width): Adjust to new signature.
10529 * alloc.c (string_overflow): New function.
10530 (Fmake_string): Use it. This doesn't change behavior, but saves
10531 a few bytes and will simplify future changes.
10532 * character.c (string_escape_byte8): Likewise.
10533 * lisp.h (string_overflow): New decl.
10535 Fixups, following up to the user-interface timestamp change.
10536 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
10537 for UI timestamps, instead of unsigned long.
10538 * msdos.c (mouse_get_pos): Likewise.
10539 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
10540 * w32gui.h (Time): Define by including "systime.h" rather than by
10541 declaring it ourselves. (Bug#8664)
10543 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
10544 * image.c (clear_image_cache): Likewise.
10546 * term.c (term_mouse_position): Don't assume time_t wraparound.
10548 Be more systematic about user-interface timestamps.
10549 Before, the code sometimes used 'Time', sometimes 'unsigned long',
10550 and sometimes 'EMACS_UINT', to represent these timestamps.
10551 This change causes it to use 'Time' uniformly, as that's what X uses.
10552 This makes the code easier to follow, and makes it easier to catch
10553 integer overflow bugs such as Bug#8664.
10554 * frame.c (Fmouse_position, Fmouse_pixel_position):
10555 Use Time, not unsigned long, for user-interface timestamps.
10556 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
10557 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
10558 * keyboard.h (last_event_timestamp): Likewise.
10559 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
10560 * menu.h (xmenu_show): Likewise.
10561 * term.c (term_mouse_position): Likewise.
10562 * termhooks.h (struct input_event.timestamp): Likewise.
10563 (struct terminal.mouse_position_hook): Likewise.
10564 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
10565 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
10566 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
10567 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
10568 what it was before.
10569 * menu.h, termhooks.h: Include "systime.h", for Time.
10571 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
10572 Don't assume that the difference between two unsigned long values
10573 can fit into an integer. At this point, we know button_down_time
10574 <= event->timestamp, so the difference must be nonnegative, so
10575 there's no need to cast the result if double-click-time is
10576 nonnegative, as it should be; check that it's nonnegative, just in
10577 case. This bug is triggered when events are more than 2**31 ms
10578 apart (about 25 days). (Bug#8664)
10580 * xselect.c (last_event_timestamp): Remove duplicate decl.
10581 (x_own_selection): Remove needless cast to unsigned long.
10583 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
10584 that always fit in int. Use a sentinel instead of a counter, to
10585 avoid a temp and to allay GCC's concerns about possible int overflow.
10586 * frame.h (struct frame): Use int for menu_bar_items_used
10587 instead of EMACS_INT, since it always fits in int.
10589 * menu.c (grow_menu_items): Check for int overflow.
10591 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
10593 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
10594 Before, the code was not consistent. These values cannot exceed
10595 2**31 - 1 so there's no need to make them unsigned.
10596 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
10597 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
10598 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
10599 as modifiers.
10600 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
10602 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
10603 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
10604 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
10605 presumably because the widths might not match.
10607 * window.c (size_window): Avoid needless test at loop start.
10609 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
10611 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
10613 2011-05-12 Drew Adams <drew.adams@oracle.com>
10615 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
10617 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10619 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
10620 `width' to `bar_area_x' and `bar_area_width', respectively.
10621 (x_scroll_run): Take account of fringe background extension.
10623 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
10624 Rename local vars `left' and `width' to `bar_area_x' and
10625 `bar_area_width', respectively.
10626 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
10627 background extension.
10629 2011-05-10 Jim Meyering <meyering@redhat.com>
10631 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
10633 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
10635 * image.c (Finit_image_library): Return t for built-in image types,
10636 like pbm and xbm. (Bug#8640)
10638 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
10640 * w32menu.c (set_frame_menubar): Fix submenu allocation.
10642 2011-05-07 Eli Zaretskii <eliz@gnu.org>
10644 * w32console.c (Fset_screen_color): Doc fix.
10645 (Fget_screen_color): New function.
10646 (syms_of_ntterm): Defsubr it.
10648 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
10649 unlink the temporary file if Fcall_process didn't create it in the
10650 first place.
10651 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
10652 child process will be redirected to a file specified with `:file'.
10653 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
10654 cue to call_process_cleanup not to close that handle.
10656 2011-05-07 Ben Key <bkey76@gmail.com>
10658 * makefile.w32-in: The bootstrap-temacs rule now makes use of
10659 one of two shell specific rules, either bootstrap-temacs-CMD or
10660 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
10661 to the previous implementation of the bootstrap-temacs rule.
10662 The bootstrap-temacs-CMD rule is similar to the previous
10663 implementation of the bootstrap-temacs rule except that it
10664 makes use of the ESC_CFLAGS variable instead of the CFLAGS
10665 variable.
10667 These changes, along with some changes to nt/configure.bat,
10668 nt/gmake.defs, and nt/nmake.defs, are required to extend my
10669 earlier fix to add support for --cflags and --ldflags options
10670 that include quotes so that it works whether make uses cmd or
10671 sh as the shell.
10673 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
10675 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
10676 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
10677 is a constant.
10678 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
10679 a string. Handle both cases.
10680 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
10681 (Fdbus_register_method): Use Qinvalid_function.
10683 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
10685 * makefile.w32-in: Update dependencies.
10686 (LISP_H): Add inttypes.h and stdin.h.
10687 (PROCESS_H): Add unistd.h.
10689 2011-05-06 Eli Zaretskii <eliz@gnu.org>
10691 * lread.c: Include limits.h (fixes the MS-Windows build broken by
10692 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
10694 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
10696 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
10698 * term.c (vfatal): Remove stray call to va_end.
10699 It's not needed and the C Standard doesn't allow it here anyway.
10701 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
10702 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
10704 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
10705 bytes.
10707 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
10709 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
10711 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
10713 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
10715 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
10717 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
10718 * charset.c (Fdefine_charset_internal): Don't initialize
10719 charset.code_space[15]. The value was garbage, on hosts with
10720 32-bit int (Bug#8600).
10722 * lread.c (read_integer): Be more consistent with string-to-number.
10723 Use string_to_number to do the actual conversion; this avoids
10724 rounding errors and fixes some other screwups. Without this fix,
10725 for example, #x1fffffffffffffff was misread as -2305843009213693952.
10726 (digit_to_number): Move earlier, for benefit of read_integer.
10727 Return -1 if the digit is out of range for the base, -2 if it is
10728 not a digit in any supported base. (Bug#8602)
10730 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
10732 * dispnew.c (scrolling_window): Return 1 if we scrolled,
10733 to match comment at start of function. This also removes a
10734 GCC warning about overflow in a 32+64-bit port.
10736 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
10738 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
10739 Reported by Stefan Monnier in
10740 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
10741 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
10742 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
10744 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
10745 (EMACS_UINTPTR): Likewise, with uintptr_t.
10747 * lisp.h: Prefer 64-bit EMACS_INT if available.
10748 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
10749 on 32-bit hosts that have 64-bit int, so that they can access
10750 large files.
10751 However, temporarily disable this change unless the temporary
10752 symbol WIDE_EMACS_INT is defined.
10754 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
10756 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
10757 This removes an assumption that EMACS_INT and long are the same
10758 width as pointers. The assumption is true for Emacs porting targets
10759 now, but we want to make other targets possible.
10760 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
10761 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
10762 In the rest of the code, change types of integers that hold casted
10763 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
10764 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
10765 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
10766 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
10767 No need to cast type when ORing.
10768 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
10769 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
10770 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
10771 assume EMACS_INT is the same width as char *.
10772 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
10773 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
10774 Remove no-longer-needed casts.
10775 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
10776 (xg_tool_bar_help_callback, xg_make_tool_item):
10777 Use EMACS_INTPTR to hold an integer
10778 that will be cast to void *; this can avoid a GCC warning
10779 if EMACS_INT is not the same width as void *.
10780 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
10781 * xdisp.c (display_echo_area_1, resize_mini_window_1):
10782 (current_message_1, set_message_1):
10783 Use a local to convert to proper width without a cast.
10784 * xmenu.c (dialog_selection_callback): Likewise.
10786 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
10787 Also, don't assume VALBITS / RAND_BITS is less than 5,
10788 and don't rely on undefined behavior when shifting a 1 left into
10789 the sign bit.
10790 * lisp.h (get_random): Change signature to match.
10792 * lread.c (hash_string): Use size_t, not int, for hash computation.
10793 Normally we prefer signed values; but hashing is special, because
10794 it's better to use unsigned division on hash table sizes so that
10795 the remainder is nonnegative. Also, size_t is the natural width
10796 for hashing into memory. The previous code used 'int', which doesn't
10797 retain enough info to hash well into very large tables.
10798 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
10800 * dbusbind.c: Don't possibly lose pointer info when converting.
10801 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
10802 Use XPNTR rather than XHASH, so that the high-order bits of
10803 the pointer aren't lost when converting through void *.
10805 * eval.c (Fautoload): Don't double-shift a pointer.
10807 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
10809 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
10811 * gnutls.c (DEF_GNUTLS_FN):
10812 * image.c (DEF_IMGLIB_FN): Make function pointers static.
10814 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
10816 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
10817 marker. (Bug#8610)
10819 2011-05-05 Eli Zaretskii <eliz@gnu.org>
10821 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
10822 New version that can reserve upto 2GB of heap space.
10824 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
10826 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
10828 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
10830 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
10831 `gnutls_certificate_set_x509_key_file'.
10833 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
10835 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
10836 Update dependencies.
10838 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
10840 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
10841 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
10842 Remove unused parameter `fildes'.
10843 * process.c (read_process_output, send_process): Don't pass it.
10845 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
10847 Fix previous change: the library cache is defined in w32.c.
10848 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
10849 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
10851 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
10853 Implement dynamic loading of GnuTLS on Windows.
10855 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
10856 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
10857 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
10858 Declare.
10860 * gnutls.c (Qgnutls_dll): Define.
10861 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
10862 (gnutls_*): Declare function pointers.
10863 (init_gnutls_functions): New function to initialize function pointers.
10864 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
10865 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
10866 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
10867 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
10868 (emacs_gnutls_write, emacs_gnutls_read)
10869 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
10870 (Fgnutls_available_p): New function.
10871 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
10872 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.

10877 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
10878 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
10879 (w32_delayed_load): Move to w32.c.
10881 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
10883 * w32.c (QCloaded_from, Vlibrary_cache): Define.
10884 (w32_delayed_load): Move from image.c. When loading a library, record
10885 its filename in the :loaded-from property of the library id.
10886 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
10887 Initialize and staticpro them.
10888 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
10890 * process.c: Include lisp.h before w32.h, not after.
10891 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
10892 instead of gnutls_record_check_pending.
10894 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
10896 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
10898 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
10899 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
10900 as passed in.
10902 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
10904 * xterm.c (x_set_frame_alpha): Do not set property on anything
10905 else than FRAME_X_OUTER_WINDOW (Bug#8608).
10907 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
10909 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
10911 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
10913 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
10914 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

10920 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
10921 (Qgnutls_bootprop_callbacks_verify): Make static.
10923 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
10925 * callproc.c: Indentation fixup.
10927 * sysdep.c (wait_for_termination_1): Make static.
10928 (wait_for_termination, interruptible_wait_for_termination):
10929 Move after wait_for_termination_1.
10931 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
10933 * sysdep.c (interruptible_wait_for_termination): New function
10934 which is like wait_for_termination, but allows keyboard
10935 interruptions.
10937 * callproc.c (Fcall_process): Add (:file "file") as an option for
10938 the STDOUT buffer.
10939 (Fcall_process_region): Ditto.
10941 2011-04-30 Eli Zaretskii <eliz@gnu.org>
10943 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
10944 rather than `XVECTOR (FOO)->size'.
10946 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
10947 inttypes.h, as a gnulib replacement is used if it not available in
10948 system headers.
10950 2011-04-21 Eli Zaretskii <eliz@gnu.org>
10952 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
10953 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
10954 of MOST_POSITIVE_FIXNUM. (Bug#8528)
10956 * coding.c (coding_alloc_by_realloc): Error out if destination
10957 will grow beyond MOST_POSITIVE_FIXNUM.
10958 (decode_coding_emacs_mule): Abort if there isn't enough place in
10959 charbuf for the composition carryover bytes. Reserve an extra
10960 space for up to 2 characters produced in a loop.
10961 (decode_coding_iso_2022): Abort if there isn't enough place in
10962 charbuf for the composition carryover bytes.
10964 2011-04-21 Eli Zaretskii <eliz@gnu.org>

10967 aborting when %lld or %lll format is passed.
10968 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
10969 %llo or %llx format is passed. (Bug#8545)
10971 * window.c (window_scroll_line_based): Use a marker instead of
10972 simple variables to record original value of point. (Bug#7952)
10974 * doprnt.c (doprnt): Fix the case where a multibyte sequence
10975 produced by %s or %c overflows available buffer space. (Bug#8545)
10977 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
10979 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
10980 (SIZE_MAX): Move defn after all includes, as they might #define it.
10982 2011-04-28 Juanma Barranquero <lekktu@gmail.com>

10992 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
10994 2011-04-28 Eli Zaretskii <eliz@gnu.org>
10996 * doprnt.c (doprnt): Don't return value smaller than the buffer
10997 size if the message was truncated. (Bug#8545).
10999 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11001 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
11002 (Fx_window_property): #if-0 the whole functions, not just the bodies.
11004 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11006 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
11008 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
11010 * makefile.w32-in: Update dependencies.
11012 2011-04-27 Eli Zaretskii <eliz@gnu.org>
11014 Improve `doprnt' and its usage. (Bug#8545)
11015 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
11016 `format_end'. Remove support for %l as a conversion specifier.
11017 Don't use xrealloc. Improve diagnostics when the %l size modifier
11018 is used. Update the commentary.
11020 * eval.c (verror): Simplify calculation of size_t.
11022 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
11023 messages.
11025 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
11027 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
11028 change.
11030 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11032 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
11033 This makes this file independent of the recent pseudovector change.
11035 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
11037 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
11039 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
11040 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
11041 Remove unused local.
11042 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
11044 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
11045 GCC 4.6.0 optimizes based on type-based alias analysis.
11046 For example, if b is of type struct buffer * and v of type struct
11047 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
11048 != &v->size, and therefore "v->size = 1; b->size = 2; return
11049 v->size;" must therefore return 1. This assumption is incorrect
11050 for Emacs, since it type-puns struct Lisp_Vector * with many other
11051 types. To fix this problem, this patch adds a new type struct
11052 vectorlike_header that documents the constraints on layout of vectors
11053 and pseudovectors, and helps optimizing compilers not get fooled
11054 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
11055 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
11056 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
11057 the size member.
11058 (XSETPVECTYPE): Rewrite in terms of new macro.
11059 (XSETPVECTYPESIZE): New macro, specifying both type and size.
11060 This is a bit clearer, and further avoids the possibility of
11061 undesirable aliasing.
11062 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
11063 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
11064 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
11065 since Lisp_Subr is a special case (no "next" field).
11066 (ASIZE): Now uses header.size rather than size.
11067 All previous uses of XVECTOR (foo)->size replaced to use this macro,
11068 to avoid the hassle of writing XVECTOR (foo)->header.size.
11069 (struct vectorlike_header): New type.
11070 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
11071 object, to help avoid aliasing.
11072 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
11073 (SUBRP): Likewise, since Lisp_Subr is a special case.
11074 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
11075 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
11076 (struct Lisp_Hash_Table): Combine first two members into a single
11077 struct vectorlike_header member. All uses of "size" and "next" members
11078 changed to be "header.size" and "header.next".
11079 * buffer.h (struct buffer): Likewise.
11080 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
11081 * frame.h (struct frame): Likewise.
11082 * process.h (struct Lisp_Process): Likewise.
11083 * termhooks.h (struct terminal): Likewise.
11084 * window.c (struct save_window_data, struct saved_window): Likewise.
11085 * window.h (struct window): Likewise.
11086 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
11087 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
11088 * buffer.c (init_buffer_once): Likewise.
11089 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
11090 special case.
11091 * process.c (Fformat_network_address): Use local var for size,
11092 for brevity.
11094 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
11096 Make the Lisp reader and string-to-float more consistent (Bug#8525)
11097 * data.c (atof): Remove decl; no longer used or needed.
11098 (digit_to_number): Move to lread.c.
11099 (Fstring_to_number): Use new string_to_number function, to be
11100 consistent with how the Lisp reader treats infinities and NaNs.
11101 Do not assume that floating-point numbers represent EMACS_INT
11102 without losing information; this is not true on most 64-bit hosts.
11103 Avoid double-rounding errors, by insisting on integers when
11104 parsing non-base-10 numbers, as the documentation specifies.
11105 * lisp.h (string_to_number): New decl, replacing ...
11106 (isfloat_string): Remove.
11107 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
11108 (read1): Do not accept +. and -. as integers; this
11109 appears to have been a coding error. Similarly, do not accept
11110 strings like +-1e0 as floating point numbers. Do not report
11111 overflow for integer overflows unless the base is not 10 which
11112 means we have no simple and reliable way to continue.
11113 Break out the floating-point parsing into a new
11114 function string_to_number, so that Fstring_to_number parses
11115 floating point numbers consistently with the Lisp reader.
11116 (digit_to_number): Move here from data.c. Make it static inline.
11117 (E_CHAR, EXP_INT): Remove, replacing with ...
11118 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
11119 (string_to_number): New function, replacing isfloat_string.
11120 This function checks for valid syntax and produces the resulting
11121 Lisp float number too. Rework it so that string-to-number
11122 no longer mishandles examples like "1.0e+". Use strtoumax,
11123 so that overflow for non-base-10 numbers is reported only when
11124 there's no portable and simple way to convert to floating point.
11126 * textprop.c (set_text_properties_1): Rewrite for clarity,
11127 and to avoid GCC warning about integer overflow.
11129 * intervals.h (struct interval): Use EMACS_INT for members
11130 where EMACS_UINT might cause problems. See
11131 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
11132 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
11133 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
11134 All uses changed.
11135 (offset_intervals): Tell GCC not to worry about length overflow
11136 when negating a negative length.
11138 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
11139 (overrun_check_free): Likewise.
11141 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
11142 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
11143 word size.
11145 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11146 (gnutls_make_error): Rename local to avoid shadowing.
11147 (gnutls_emacs_global_deinit): ifdef out; not used.
11148 (Fgnutls_boot): Use const for pointer to readonly storage.
11149 Comment out unused local. Fix pointer signedness problems.
11151 * lread.c (openp): Don't stuff size_t into an 'int'.
11152 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
11153 about possible signed overflow.
11155 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11156 (GDK_KEY_g): Don't define if already defined.
11157 (xg_prepare_tooltip): Avoid pointer signedness problem.
11158 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
11160 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
11161 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
11163 * xfns.c (Fx_window_property): Simplify a bit,
11164 to make a bit faster and to avoid GCC 4.6.0 warning.
11165 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
11167 * fns.c (internal_equal): Don't assume size_t fits in int.
11169 * alloc.c (compact_small_strings): Tighten assertion a little.
11171 Replace pEd with more-general pI, and fix some printf arg casts.
11172 * lisp.h (pI): New macro, generalizing old pEd macro to other
11173 conversion specifiers. For example, use "...%"pI"d..." rather
11174 than "...%"pEd"...".
11175 (pEd): Remove. All uses replaced with similar uses of pI.
11176 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
11177 * alloc.c (check_pure_size): Don't overflow by converting size to int.
11178 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
11179 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
11180 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
11181 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
11182 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
11183 64-bit hosts.
11184 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
11185 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
11186 * print.c (safe_debug_print, print_object): Likewise.
11187 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
11188 to int.
11189 Use pI instead of if-then-else-abort. Use %p to avoid casts,
11190 avoiding the 0 flag, which is not portable.
11191 * process.c (Fmake_network_process): Use pI to avoid cast.
11192 * region-cache.c (pp_cache): Likewise.
11193 * xdisp.c (decode_mode_spec): Likewise.
11194 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
11195 behavior on 64-bit hosts with printf arg.
11196 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
11197 (x_stop_queuing_selection_requests): Likewise.
11198 (x_get_window_property): Don't truncate byte count to an 'int'
11199 when tracing.
11201 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
11202 here, since it parses constructs like leading '-' and spaces,
11203 which are not wanted; and it overflows with large numbers.
11204 Instead, simply match F[0-9]+, which is what is wanted anyway.
11206 * alloc.c: Remove unportable assumptions about struct layout.
11207 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
11208 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
11209 (allocate_vectorlike, make_pure_vector): Use the new macros,
11210 plus offsetof, to remove unportable assumptions about struct layout.
11211 These assumptions hold on all porting targets that I know of, but
11212 they are not guaranteed, they're easy to remove, and removing them
11213 makes further changes easier.
11215 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
11216 This doesn't fix a bug but makes the code clearer.
11217 (string_overrun_cookie): Now const. Use initializers that
11218 don't formally overflow signed char, to avoid warnings.
11219 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
11220 can cause Emacs to crash when string overrun checking is enabled.
11221 (allocate_buffer): Don't assume sizeof (struct buffer) is a
11222 multiple of sizeof (EMACS_INT); it need not be, if
11223 alignof(EMACS_INT) < sizeof (EMACS_INT).
11224 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
11226 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
11228 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
11230 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
11232 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
11233 supposed to be handshaking. (Bug#8556)
11234 Reported by Paul Eggert <eggert@cs.ucla.edu>.
11236 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
11238 * lisp.h (Qdebug): List symbol.
11239 * eval.c (Qdebug): Restore global linkage.
11240 * keyboard.c (debug-on-event): New variable.
11241 (handle_user_signal): Break into debugger when debug-on-event
11242 matches the current signal symbol.
11244 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
11246 * alloc.c (check_sblock, check_string_bytes)
11247 (check_string_free_list): Convert to standard C.
11249 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
11251 * w32.c (emacs_gnutls_push): Fix typo.
11253 2011-04-25 Eli Zaretskii <eliz@gnu.org>
11255 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
11256 "cast to pointer from integer of different size".
11258 Improve doprnt and its use in verror. (Bug#8545)
11259 * doprnt.c (doprnt): Document the set of format control sequences
11260 supported by the function. Use SAFE_ALLOCA instead of always
11261 using `alloca'.
11263 * eval.c (verror): Don't limit the buffer size at size_max-1, that
11264 is one byte too soon. Don't use xrealloc; instead xfree and
11265 xmalloc anew.
11267 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
11269 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
11270 callbacks stage.
11272 * gnutls.c: Renamed global_initialized to
11273 gnutls_global_initialized. Added internals for the
11274 :verify-hostname-error, :verify-error, and :verify-flags
11275 parameters of `gnutls-boot' and documented those parameters in the
11276 docstring. Start callback support.
11277 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
11278 unless a fatal error occurred. Call gnutls_alert_send_appropriate
11279 on error. Return error code.
11280 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
11281 (emacs_gnutls_read): Likewise.
11282 (Fgnutls_boot): Return handshake error code.
11283 (emacs_gnutls_handle_error): New function.

11287 (emacs_gnutls_push): Likewise.
11289 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
11290 (emacs_gnutls_push): Likewise.

11294 * process.c (wait_reading_process_output): Check if GnuTLS
11295 buffered some data internally if no FDs are set for TLS
11296 connections.

11307 commentary.
11309 * textprop.c (syms_of_textprop): Remove dead code.
11310 (copy_text_properties): Delete obsolete commentary about an
11311 interface that was deleted long ago. Fix typos in the description
11312 of arguments.

11315 to changes in oldXMenu/XMenu.h from 2011-04-16.
11316 <menu_help_message, prev_menu_help_message>: Constify.
11317 (IT_menu_make_room): menu->help_text is now `const char **';
11318 adjust.

11321 to changes in oldXMenu/XMenu.h from 2011-04-16.
11322 (struct XMenu): Declare `help_text' `const char **'.
11324 * xfaces.c <Qunspecified>: Make extern again.
11326 * syntax.c: Include sys/types.h before including regex.h, as
11327 required by POSIX.
11329 * doc.c (get_doc_string): Improve the format passed to `error'.
11331 * doprnt.c (doprnt): Improve commentary.
11333 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
11335 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
11336 them with etags.
11338 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
11339 changes in globals.h immediately force recompilation.
11340 (TAGS): Depend on $(CURDIR)/m/intel386.h and
11341 $(CURDIR)/s/ms-w32.h.
11342 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.
11344 * character.c (Fchar_direction): Function deleted.
11345 (syms_of_character): Don't defsubr it.
11346 <char-direction-table>: Deleted.
11348 2011-04-23 Eli Zaretskii <eliz@gnu.org>
11350 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
11351 * doprnt.c: Include limits.h.
11352 (SIZE_MAX): New macro.
11353 (doprnt): Return a size_t value. 2nd arg is now size_t.
11354 Many local variables are now size_t instead of int or unsigned.
11355 Improve overflow protection. Support `l' modifier for integer
11356 conversions. Support %l conversion. Don't assume an EMACS_INT
11357 argument for integer conversions and for %c.
11359 * lisp.h (doprnt): Restore prototype.
11361 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
11362 $(SRC)/character.h.
11364 * Makefile.in (base_obj): Add back doprnt.o.
11366 * deps.mk (doprnt.o): Add back prerequisites.
11367 (callint.o): Depend on character.h.
11369 * eval.c (internal_lisp_condition_case): Include the handler
11370 representation in the error message.
11371 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
11372 when breaking from the loop.
11374 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
11376 * callint.c (Fcall_interactively): When displaying error message
11377 about invalid control letter, pass the character's codepoint, not
11378 a pointer to its multibyte form. Improve display of the character
11379 in octal and display also its hex code.
11381 * character.c (char_string): Use %x to display the (unsigned)
11382 codepoint of an invalid character, to avoid displaying a bogus
11383 negative value.
11385 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
11386 `error', not SYMBOL_NAME itself.
11388 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
11389 character arguments to `error'.
11391 * charset.c (check_iso_charset_parameter): Fix incorrect argument
11392 to `error' in error message about FINAL_CHAR argument. Make sure
11393 FINAL_CHAR is a character, and use %c when it is passed as
11394 argument to `error'.
11396 2011-04-23 Eli Zaretskii <eliz@gnu.org>
11398 * s/ms-w32.h (localtime): Redirect to sys_localtime.

11455 * data.c (arith_error): Mark with NO_RETURN if it doesn't return.
11457 * alloc.c (bytes_used_when_full, SPARE_MEMORY, BYTES_USED):
11458 Define only if needed.
11460 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
11461 by pacifying GCC about it. Maybe it's time to retire it?
11462 * xfaces.c (USG, __TIMEVAL__): Likewise.
11464 * dispextern.h (struct redisplay_interface): Rename param
11465 to avoid shadowing.
11466 * termhooks.h (struct terminal): Likewise.
11467 * xterm.c (xembed_send_message): Likewise.
11469 * insdel.c (make_gap_smaller): Define only if
11470 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
11472 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
11473 it.
11475 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
11476 so that we aren't warned about unused symbols.
11478 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
11480 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).

11487 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
11488 (x_dispatch_event): Declare static if USE_GTK, and
11489 define if USE_GTK || USE_X_TOOLKIT.
11490 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
11491 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.

11510 only if HAVE_X_WINDOWS && !USE_X_TOOLKIT.
11512 * bitmaps: Change bitmaps from unsigned char back to the X11
11513 compatible char. Avoid the old compiler warnings about
11514 out-of-range initializers by using, for example, '\xab' rather
11515 than 0xab.
11517 * xgselect.c (xgselect_initialize): Check vs interface
11518 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).
11520 * xmenu.c (xmenu_show): Rename parm to avoid shadowing.
11522 * xterm.c (x_create_toolkit_scroll_bar): Use const * for pointers
11523 to read-only memory.

11583 * nsfont.m: Fixed bugs in ns_get_family and

11589 deallocate these memory blocks.

11957 alloc.c: Import and export fewer symbols, and remove unused items.
11958 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
11959 is defined.
11960 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
11961 it's not optimized away by whole-program optimization.
11962 (message_enable_multibyte, free_misc): Remove.
11963 (catchlist, handlerlist, mark_backtrace):
11964 Declare only if BYTE_MARK_STACK.
11965 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
11966 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
11967 (message_enable_multibyte): Remove decl.
11968 (free_misc, interval_free_list, float_block, float_block_index):
11969 (n_float_blocks, float_free_list, cons_block, cons_block_index):
11970 (cons_free_list, last_marked_index):
11971 Now static.
11972 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
11973 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
11974 (mark_backtrace): Define only if BYTE_MARK_STACK.
11975 * xdisp.c (message_enable_multibyte): Now static.
11977 Declare Lisp_Object Q* variables to be 'static' if not exported.
11978 This makes it easier for human readers (and static analyzers)
11979 to see whether these variables are used from other modules.
11980 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
11981 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
11982 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
11983 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:
11984 * lread.c, macros.c, minibuf.c, print.c, process.c, search.c:
11985 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
11986 * xmenu.c, xselect.c:
11987 Declare Q* vars static if they are not used in other modules.
11988 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
11989 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
11990 Remove decls of unexported vars.
11991 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
11993 * lisp.h (DEFINE_FUNC): Make sname 'static'.
11995 Make Emacs functions such as Fatom 'static' by default.
11996 This makes it easier for human readers (and static analyzers)
11997 to see whether these functions can be called from other modules.
11998 DEFUN now defines a static function. To make the function external
11999 so that it can be used in other C modules, use the new macro DEFUE.
12000 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
12001 (Finit_image_library):
12002 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
12003 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
12004 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
12005 Remove decls, since these functions are now static.
12006 (Funintern, Fget_internal_run_time): New decls, since these functions
12007 were already external.
12009 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
12010 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
12011 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
12012 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
12013 * keyboard.c, keymap.c, lread.c:
12014 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
12015 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
12016 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
12017 Mark functions with DEFUE instead of DEFUN,
12018 if they are used in other modules.
12019 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
12020 decls for now-static functions.
12021 * buffer.h (Fdelete_overlay): Remove decl.
12022 * callproc.c (Fgetenv_internal): Mark as internal.
12023 * composite.c (Fremove_list_of_text_properties): Remove decl.
12024 (Fcomposition_get_gstring): New forward static decl.

12027 * doc.c (Fdocumntation_property): New forward static decl.
12028 * eval.c (Ffetch_bytecode): New forward static decl.
12029 (Funintern): Remove extern decl; now in .h file where it belongs.
12030 * fileio.c (Fmake_symbolic_link): New forward static decl.
12031 * image.c (Finit_image_library): New forward static decl.
12032 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
12033 * intervals.h (Fprevious_property_change):
12034 (Fremove_list_of_text_properties): Remove decls.
12035 * keyboard.c (Fthis_command_keys): Remove decl.
12036 (Fcommand_execute): New forward static decl.
12037 * keymap.c (Flookup_key): New forward static decl.
12038 (Fcopy_keymap): Now static.
12039 * keymap.h (Flookup_key): Remove decl.
12040 * process.c (Fget_process): New forward static decl.
12041 (Fprocess_datagram_address): Mark as internal.

12044 * textprop.c (Fprevious_property_change): New forward static decl.
12045 * window.c (Fset_window_fringes, Fset_window_scroll_bars):
12046 Now internal.
12047 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
12048 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
12050 * editfns.c (Fformat): Remove unreachable code.
12052 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
12054 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
12055 change. (Bug#8496)
12057 2011-04-13 Eli Zaretskii <eliz@gnu.org>
12059 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
12060 when at ZV. (Bug#8487)
12062 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
12064 * charset.c (Fclear_charset_maps): Use xfree instead of free.
12065 (Bug#8437)
12066 * keyboard.c (parse_tool_bar_item): Likewise.
12067 * sound.c (sound_cleanup, alsa_close): Likewise.
12068 * termcap.c (tgetent): Likewise.
12069 * xfns.c (x_default_font_parameter): Likewise.
12070 * xsettings.c (read_and_apply_settings): Likewise.
12072 * alloc.c (overrun_check_malloc, overrun_check_realloc)
12073 (overrun_check_free): Protoize.
12075 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
12077 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
12078 since callers should never pass a negative size.
12079 Change the signature to match that of plain 'read' and 'write'; see
12080 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
12081 * lisp.h: Update prototypes of emacs_write and emacs_read.
12083 2011-04-11 Eli Zaretskii <eliz@gnu.org>
12085 * xdisp.c (redisplay_window): Don't try to determine the character
12086 position of the scroll margin if the window start point w->startp
12087 is outside the buffer's accessible region. (Bug#8468)
12089 2011-04-10 Eli Zaretskii <eliz@gnu.org>
12091 Fix write-region and its subroutines for buffers > 2GB.
12092 * fileio.c (a_write, e_write): Modify declaration of arguments and
12093 local variables to support buffers larger than 2GB.
12094 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
12096 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
12097 argument, local variables, and return value.
12099 * lisp.h: Update prototypes of emacs_write and emacs_read.
12101 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
12103 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
12105 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
12107 Fix more problems found by GCC 4.6.0's static checks.
12109 * xdisp.c (vmessage): Use a better test for character truncation.
12111 * charset.c (load_charset_map): <, not <=, for optimization,
12112 and to avoid potential problems with integer overflow.
12113 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
12114 * casetab.c (set_identity, shuffle): Likewise.
12115 * editfns.c (Fformat): Likewise.
12116 * syntax.c (skip_chars): Likewise.
12118 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
12119 This also lets GCC 4.6.0 generate slightly better loop code.
12121 * callint.c (Fcall_interactively): <, not <=, for optimization.
12122 (Fcall_interactively): Count the number of arguments produced,
12123 not the number of arguments given. This is simpler and lets GCC
12124 4.6.0 generate slightly better code.
12126 * ftfont.c: Distingish more carefully between FcChar8 and char.
12127 The previous code passed unsigned char * to a functions like
12128 strlen and xstrcasecmp that expect char *, which does not
12129 conform to the C standard.
12130 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
12131 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
12132 char * when the C standard requires it.
12134 * keyboard.c (read_char): Remove unused var.
12136 * eval.c: Port to Windows vsnprintf (Bug#8435).
12137 Include <limits.h>.
12138 (SIZE_MAX): Define if the headers do not.
12139 (verror): Do not give up if vsnprintf returns a negative count.
12140 Instead, grow the buffer. This ports to Windows vsnprintf, which
12141 does not conform to C99. Problem reported by Eli Zaretskii.
12142 Also, simplify the allocation scheme, by avoiding the need for
12143 calling realloc, and removing the ALLOCATED variable.
12145 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
12147 Remove invocations of doprnt, as Emacs now uses vsnprintf.
12148 But keep the doprint source code for now, as we might revamp it
12149 and use it again (Bug#8435).
12150 * lisp.h (doprnt): Remove.
12151 * Makefile.in (base_obj): Remove doprnt.o.
12152 * deps.mk (doprnt.o): Remove.
12154 error: Print 32- and 64-bit integers portably (Bug#8435).
12155 Without this change, on typical 64-bit hosts error ("...%d...", N)
12156 was used to print both 32- and 64-bit integers N, which relied on
12157 undefined behavior.
12158 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
12159 * lisp.h (error, verror): Mark as printf-like functions.
12160 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
12161 Report overflow in size calculations when allocating printf buffer.
12162 Do not truncate output string at its first null byte.
12163 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
12164 Truncate the output at a character boundary, since vsnprintf does not
12165 do that.
12166 * charset.c (check_iso_charset_parameter): Convert internal
12167 character to string before calling 'error', since %c now has the
12168 printf meaning.
12169 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
12170 overflow when computing char to be passed to 'error'. Do not
12171 pass Lisp_Object to 'error'; pass the integer instead.
12172 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
12173 formatted with plain %d.
12175 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
12177 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
12179 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
12181 * xterm.c (x_catch_errors): Remove duplicate declaration.
12183 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
12185 * xdisp.c, lisp.h (message_nolog): Remove; unused.
12187 2011-04-10 Jim Meyering <meyering@redhat.com>
12189 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
12190 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
12191 return ssize_t not "int", and use size_t as the buffer length.
12192 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
12193 * gnutls.h: Update declarations.
12194 * process.c (read_process_output): Use ssize_t, to match.
12195 (send_process): Likewise.
12197 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12199 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
12201 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12203 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
12204 Use unsigned char, to match FcChar8 type definition.
12206 * xterm.c (handle_one_xevent):
12207 * xmenu.c (create_and_show_popup_menu):
12208 * xselect.c (x_decline_selection_request)
12209 (x_reply_selection_request): Avoid type-punned deref of X events.
12211 2011-04-09 Eli Zaretskii <eliz@gnu.org>
12213 Fix some uses of `int' instead of EMACS_INT.
12214 * search.c (string_match_1, fast_string_match)
12215 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
12216 (scan_buffer, find_next_newline_no_quit)
12217 (find_before_next_newline, search_command, Freplace_match)
12218 (Fmatch_data): Make some `int' variables be EMACS_INT.
12220 * xdisp.c (display_count_lines): 3rd argument and return value now
12221 EMACS_INT. All callers changed.
12222 (pint2hrstr): Last argument is now EMACS_INT.
12224 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
12225 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
12226 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
12227 (decode_coding_utf_16, decode_coding_emacs_mule)
12228 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
12229 (decode_coding_ccl, decode_coding_charset)
12230 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
12231 (decode_coding_iso_2022, decode_coding_emacs_mule)
12232 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
12233 <char_offset, last_offset>: Declare EMACS_INT.
12234 (encode_coding_utf_8, encode_coding_utf_16)
12235 (encode_coding_emacs_mule, encode_invocation_designation)
12236 (encode_designation_at_bol, encode_coding_iso_2022)
12237 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
12238 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
12239 Declare EMACS_INT.
12240 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
12241 (encode_invocation_designation): Last argument P_NCHARS is now
12242 EMACS_INT.
12243 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
12244 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
12246 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
12247 All users changed.
12249 * ccl.c (Fccl_execute_on_string): Declare some variables
12250 EMACS_INT.
12252 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
12254 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
12256 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
12258 * process.c (Fformat_network_address): Doc fix.
12260 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
12262 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
12264 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
12266 * keyboard.c (read_char): Call Lisp function help-form-show,
12267 instead of using internal_with_output_to_temp_buffer.
12268 (Qhelp_form_show): New var.
12269 (syms_of_keyboard): Use DEFSYM macro.
12271 * print.c (internal_with_output_to_temp_buffer): Function deleted.
12273 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
12275 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
12277 * process.c (Flist_processes): Remove to Lisp.
12278 (list_processes_1): Delete.
12280 2011-04-06 Eli Zaretskii <eliz@gnu.org>
12282 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
12284 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
12286 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
12288 Fix more problems found by GCC 4.6.0's static checks.
12290 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
12292 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
12294 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
12296 * xdisp.c (vmessage): Mark as a printf-like function.
12298 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
12300 * sound.c (sound_warning): Don't crash if arg contains a printf format.
12302 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
12303 printf-like functions.
12304 (tiff_load): Add casts to remove these marks before passing them
12305 to system-supplied API.
12307 * eval.c (Fsignal): Remove excess argument to 'fatal'.
12309 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
12310 This avoids several warnings with gcc -Wstrict-overflow.
12311 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
12312 directly, rather than having caller test rule sign. This avoids
12313 some unnecessary tests.
12314 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
12315 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
12316 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
12318 * xfont.c (xfont_text_extents): Remove var that was set but not used.
12319 (xfont_open): Avoid unnecessary tests.
12321 * composite.c (composition_gstring_put_cache): Use unsigned integer.
12323 * composite.h, composite.c (composition_gstring_put_cache):
12324 Use EMACS_INT, not int, for length.
12326 * composite.h (COMPOSITION_DECODE_REFS): New macro,
12327 breaking out part of COMPOSITION_DECODE_RULE.
12328 (COMPOSITION_DECODE_RULE): Use it.
12329 * composite.c (get_composition_id): Remove unused local vars,
12330 by using the new macro.
12332 * textprop.c (set_text_properties_1): Change while to do-while,
12333 since the condition is always true at first.
12335 * intervals.c (graft_intervals_into_buffer): Mark var as used.
12336 (interval_deletion_adjustment): Return unsigned value.
12337 All uses changed.
12339 * process.c (list_processes_1, create_pty, read_process_output):
12340 (exec_sentinel): Remove vars that were set but not used.
12341 (create_pty): Remove unnecessary "volatile"s.
12342 (Fnetwork_interface_info): Avoid possibility of int overflow.
12343 (read_process_output): Do adaptive read buffering even if carryover.
12344 (read_process_output): Simplify nbytes computation if buffered.
12346 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
12348 * syntax.c (scan_words): Remove var that was set but not used.
12349 (update_syntax_table): Use unsigned instead of int.
12351 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
12352 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
12353 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
12355 * print.c (print_error_message): Avoid int overflow.
12357 * font.c (font_list_entities): Redo for clarity,
12358 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
12360 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
12361 (font_score): Avoid potential overflow in diff calculation.
12363 * fns.c (substring_both): Remove var that is set but not used.
12364 (sxhash): Redo loop for clarity and to avoid wraparound warning.
12366 * eval.c (funcall_lambda): Rename local to avoid shadowing.
12368 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
12369 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
12370 can always succeed if overflow has undefined behavior.
12372 * search.c (boyer_moore, wordify): Remove vars set but not used.
12373 (wordify): Omit three unnecessary tests.
12375 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

12404 that are set but not used.
12406 * xfns.c (make_invisible_cursor): Don't return garbage
12407 if XCreateBitmapFromData fails (Bug#8410).
12409 * xselect.c (x_get_local_selection, x_handle_property_notify):

12413 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
12415 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:

12422 (map_tty_color) [!defined MSDOS]: Likewise.
12424 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
12426 * coding.c: Remove vars that are set but not used.
12427 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
12428 All callers changed.
12429 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):

12436 * print.c (print_object): Remove var that is set but not used.
12438 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
12439 The gnulib version avoids calling malloc in the usual case,
12440 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
12441 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
12442 * filelock.c (current_lock_owner): Likewise.
12443 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

12445 (emacs_no_realloc_allocator): New static constant.
12446 (emacs_readlink): New function.
12447 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
12448 ../lib/careadlinkat.h.
12450 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
12452 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
12453 first non-nil return value).
12455 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>

12478 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
12480 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
12482 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
12484 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
12485 later (Bug#8403).
12487 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
12489 Add lexical binding.
12491 * window.c (Ftemp_output_buffer_show): New fun.
12492 (Fsave_window_excursion):
12493 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
12495 * lread.c (lisp_file_lexically_bound_p): New function.

12500 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
12501 Mark as dynamic.
12502 (syms_of_lread): Declare `lexical-binding'.
12504 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
12506 * keyboard.c (eval_dyn): New fun.
12507 (menu_item_eval_property): Use it.
12509 * image.c (parse_image_spec): Use Ffunctionp.
12511 * fns.c (concat, mapcar1): Accept byte-code-functions.
12513 * eval.c (Fsetq): Handle lexical vars.
12514 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
12515 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
12516 (FletX, Flet): Obey lexical binding.
12517 (Fcommandp): Handle closures.
12518 (Feval): New `lexical' arg.
12519 (eval_sub): New function extracted from Feval. Use it almost
12520 everywhere where Feval was used. Look up vars in lexical env.
12521 Handle closures.
12522 (Ffunctionp): Move from subr.el.
12523 (Ffuncall): Handle closures.
12524 (apply_lambda): Remove `eval_flags'.
12525 (funcall_lambda): Handle closures and new byte-code-functions.
12526 (Fspecial_variable_p): New function.
12527 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
12528 but without exporting it to Lisp.
12530 * doc.c (Fdocumentation, store_function_docstring):
12531 * data.c (Finteractive_form): Handle closures.
12533 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
12534 interactive spec.
12536 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
12537 New byte-codes.
12538 (exec_byte_code): New function extracted from Fbyte_code to handle new
12539 calling convention for byte-code-functions. Add new byte-codes.
12541 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
12543 * alloc.c (Fmake_symbol): Init new `declared_special' field.
12545 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
12547 * xdisp.c (redisplay_internal): Fix prototype.
12549 2011-03-31 Eli Zaretskii <eliz@gnu.org>
12551 * xdisp.c (SCROLL_LIMIT): New macro.
12552 (try_scrolling): Use it when setting scroll_limit.
12553 Limit scrolling to 100 screen lines.
12554 (redisplay_window): Even when falling back on "recentering",
12555 position point in the window according to scroll-conservatively,
12556 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
12558 (try_scrolling): When point is above the window, allow searching
12559 as far as scroll_max, or one screenful, to compute vertical
12560 distance from PT to the scroll margin position. This prevents
12561 try_scrolling from unnecessarily failing when
12562 scroll-conservatively is set to a value slightly larger than the
12563 window height. Clean up the case of PT below the margin at bottom
12564 of window: scroll_max can no longer be INT_MAX. When aggressive
12565 scrolling is in use, don't let point enter the opposite scroll
12566 margin as result of the scroll.
12567 (syms_of_xdisp) <scroll-conservatively>: Document the
12568 threshold of 100 lines for never-recentering scrolling.
12570 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
12572 * dispextern.h (move_it_by_lines):
12573 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

12575 (message_log_check_duplicate): Remove parameters `prev_bol' and
12576 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
12577 (redisplay_internal): Remove parameter `preserve_echo_area',
12578 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
12580 * indent.c (Fvertical_motion):
12581 * window.c (window_scroll_pixel_based, Frecenter):
12582 Don't pass `need_y_p' to `move_it_by_lines'.
12584 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
12586 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
12587 steal a few bits to be more compact.

12589 Remove unneeded casts.
12591 * bytecode.c (Fbyte_code): CAR and CDR can GC.

12595 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
12596 binding" message (bug#7967).

12602 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
12603 Remove unused local var.
12605 * editfns.c (Fmessage_box): Remove unused local var.
12607 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
12608 (note_mode_line_or_margin_highlight, note_mouse_highlight):
12609 Omit unused local vars.
12610 * window.c (shrink_windows): Omit unused local var.
12611 * menu.c (digest_single_submenu): Omit unused local var.
12612 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
12613 Omit unused local var.
12615 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
12616 Don't assume string length fits in int.
12617 (keyremap_step, read_key_sequence): Use size_t for sizes.

12621 instead of alloca (Bug#8344).
12623 * eval.c (Fbacktrace): Don't assume nargs fits in int.
12624 (Fbacktrace_frame): Don't assume nframes fits in int.
12626 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

12629 concerns.

12633 * cm.c (calccost): Turn while-do into do-while, for clarity.
12635 * keyboard.c (syms_of_keyboard): Use the same style as later
12636 in this function when indexing through an array. This also
12637 works around GCC bug 48267.
12639 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
12641 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
12643 * chartab.c (sub_char_table_ref_and_range): Redo for slight
12644 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
12646 * keyboard.c, keyboard.h (num_input_events): Now size_t.
12647 This avoids undefined behavior on integer overflow, and is a bit
12648 more convenient anyway since it is compared to a size_t variable.
12650 Variadic C functions now count arguments with size_t, not int.
12651 This avoids an unnecessary limitation on 64-bit machines, which
12652 caused (substring ...) to crash on large vectors (Bug#8344).

12662 * fns.c (concat): Likewise.
12663 * frame.c (x_set_frame_parameters): Likewise.
12664 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
12665 0 if not found, not -1. All callers changed.
12667 * alloc.c (garbage_collect): Don't assume stack size fits in int.
12668 (stack_copy_size): Now size_t, not int.
12669 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
12671 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
12673 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
12674 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

12690 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
12691 don't set the hook to nil, but remove the offending function instead.

12693 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
12694 Vcommand_hook_internal.

12835 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
12837 * w32term.c (x_set_glyph_string_clipping):
12838 Don't pass uninitialized region to CombineRgn.
12840 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
12842 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.

12862 2011-03-23 Julien Danjou <julien@danjou.info>
12864 * term.c (Fsuspend_tty, Fresume_tty):
12865 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
12866 * window.c (temp_output_buffer_show):
12867 * insdel.c (signal_before_change):
12868 * frame.c (Fhandle_switch_frame):
12869 * fileio.c (Fdo_auto_save):
12870 * emacs.c (Fkill_emacs):
12871 * editfns.c (save_excursion_restore):
12872 * cmds.c (internal_self_insert):
12873 * callint.c (Fcall_interactively):
12874 * buffer.c (Fkill_all_local_variables):
12875 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
12876 Use Frun_hooks.
12877 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
12878 unconditionally since it does the check itself.
12880 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
12882 Fix more problems found by GCC 4.5.2's static checks.
12884 * coding.c (encode_coding_raw_text): Avoid unnecessary test
12885 the first time through the loop, since we know p0 < p1 then.
12886 This also avoids a gcc -Wstrict-overflow warning.
12888 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
12889 leading to a memory leak, possible in functions like
12890 load_charset_map_from_file that can allocate an unbounded number
12891 of objects (Bug#8318).
12893 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
12894 that could (at least in theory) be that large.
12896 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
12897 This is less likely to overflow, and avoids undefined behavior if
12898 overflow does occur. All callers changed. Use strtoul to scan
12899 for the unsigned long integer.
12900 (pint2hrstr): Simplify and tune code slightly.
12901 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
12903 * scroll.c (do_scrolling): Work around GCC bug 48228.
12904 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

12907 This also avoids a warning with gcc -Wstrict-overflow.
12908 (validate_x_resource_name): Simplify count usage.
12909 This also avoids a warning with gcc -Wstrict-overflow.
12911 * fileio.c (Fcopy_file): Report error if fchown or fchmod
12912 fail (Bug#8306).
12914 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
12916 * process.c (Fmake_network_process): Use socklen_t, not int,
12917 where POSIX says socklen_t is required in portable programs.
12918 This fixes a porting bug on hosts like 64-bit HP-UX, where
12919 socklen_t is wider than int (Bug#8277).
12920 (Fmake_network_process, server_accept_connection):
12921 (wait_reading_process_output, read_process_output):
12922 Likewise.
12924 * process.c: Rename or move locals to avoid shadowing.
12925 (list_processes_1, Fmake_network_process):

12931 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
12932 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
12934 Make tparam.h and terminfo.c consistent.
12935 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
12936 Include tparam.h instead, since it declares them.
12937 * cm.h (PC): Remove extern decl; tparam.h now does this.
12938 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
12939 * terminfo.c: Include tparam.h, to check interfaces.
12940 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
12941 (tparam): Adjust signature to match interface in tparam.h;
12942 this removes some undefined behavior. Check that outstring and len
12943 are zero, which they always are with Emacs.
12944 * tparam.h (PC, BC, UP): New extern decls.
12946 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
12947 (xftfont_open): Rename locals to avoid shadowing.
12949 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
12950 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
12951 (OTF_TAG_SYM): Omit macro if not needed.

12959 * xml.c (make_dom): Now static.
12961 * composite.c (composition_compute_stop_pos): Rename local to
12962 avoid shadowing.
12963 (composition_reseat_it): Remove unused locals.
12964 (find_automatic_composition, composition_adjust_point): Likewise.
12965 (composition_update_it): Mark var as initialized.
12966 (find_automatic_composition): Mark vars as initialized,
12967 with a FIXME (Bug#8290).

12972 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
12973 (BUF_DEC_POS): Be more systematic about renaming local temporaries
12974 to avoid shadowing.
12976 * textprop.c (property_change_between_p): Remove; unused.
12978 * intervals.c (interval_start_pos): Now static.
12980 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

12983 Rename locals to avoid shadowing.
12985 * sound.c (wav_play, au_play, Fplay_sound_internal):
12986 Fix pointer signedness.
12987 (alsa_choose_format): Remove unused local var.
12988 (wav_play): Initialize a variable to 0, to prevent undefined
12989 behavior (Bug#8278).
12991 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
12993 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
12995 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
12996 clobbering (Bug#8298).
12997 * sysdep.c (sys_subshell): Likewise.
12998 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
13000 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
13001 This should get cleaned up, so that child_setup has the
13002 same signature on all platforms.
13004 * callproc.c (call_process_cleanup): Now static.
13005 (relocate_fd): Rename locals to avoid shadowing.
13007 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
13009 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
13010 not to be necessary, and produces flickering.
13012 2011-03-20 Glenn Morris <rgm@gnu.org>
13014 * config.in: Remove file.
13016 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
13018 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
13019 are now in src/globals.h.
13020 (syms_of_minibuf): Remove spurious & from previous change.
13022 2011-03-20 Leo Liu <sdl.web@gmail.com>
13024 * minibuf.c (completing-read-function): New variable.
13025 (completing-read-default): Rename from completing-read.
13026 (completing-read): Call completing-read-function.
13028 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
13030 * xfaces.c (Fx_load_color_file):
13031 Read color file from absolute filename (bug#8250).
13033 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
13035 * makefile.w32-in: Update dependencies.
13037 2011-03-17 Eli Zaretskii <eliz@gnu.org>
13039 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.
13041 2011-03-17 Paul Eggert <eggert@cs.ucla.edu>
13043 Fix more problems found by GCC 4.5.2's static checks.

13046 (sigchld_handler): Now static.
13048 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
13049 That way, the code declares only the vars that it needs.
13050 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
13051 * s/cygwin.h (PTY_ITERATION): Likewise.
13052 * s/darwin.h (PTY_ITERATION): Likewise.

13061 Define only if needed.
13063 * unexelf.c (unexec): Name an expression,
13064 to avoid gcc -Wbad-function-cast warning.
13065 Use a different way to cause a compilation error if anyone uses
13066 n rather than nn, a way that does not involve shadowing.
13067 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
13069 * deps.mk (unexalpha.o): Remove; unused.
13071 New file unexec.h, the (simple) interface for unexec (Bug#8267).
13072 * unexec.h: New file.
13073 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
13074 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
13075 Depend on unexec.h.
13076 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
13077 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
13078 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
13079 Change as necessary to match prototype in unexec.h.
13081 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
13082 shadowing.
13083 (back_comment, skip_chars): Mark vars as initialized.

13096 * font.c (font_unparse_fcname): Abort in an "impossible" situation
13097 instead of using an uninitialized var.
13098 (font_sort_entities): Mark var as initialized.
13100 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
13102 * font.c (font_unparse_xlfd): Don't mix pointers to variables with
13103 pointers to constants.
13104 (font_parse_fcname): Remove unused vars.
13105 (font_delete_unmatched): Now static.

13115 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
13117 * alloc.c (mark_backtrace): Move decl from here ...

13120 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
13121 (Fdefvar): Rewrite so as not to use empty "else".

13131 Move decls here, to check interfaces.
13132 * process.c (get_operating_system_release): Move decl to lisp.h.
13133 * xrdb.c (get_system_name): Likewise.
13134 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
13135 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
13136 some of which prompt warnings from gcc -Wbad-function-cast.
13137 (Fformat_time_string, Fencode_time, Finsert_char):
13138 (Ftranslate_region_internal, Fformat):
13139 Rename or remove local vars to avoid shadowing.
13140 (Ftranslate_region_internal): Mark var as initialized.
13142 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
13143 avoid shadowing.
13145 * lisp.h (eassert): Check that the argument compiles, even if
13146 ENABLE_CHECKING is not defined.
13148 * data.c (Findirect_variable): Name an expression, to avoid

13157 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
13158 Rename locals to avoid shadowing.
13159 (mark_stack): Move local variables into the #ifdef region where
13160 they're used.
13161 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
13162 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
13163 needed otherwise.
13164 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
13165 (GC_STRING_CHARS): Remove; not used.
13166 (Fmemory_limit): Cast sbrk's returned value to char *.
13168 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
13169 avoids undefined behavior in theory.
13171 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
13173 Use functions, not macros, for up- and down-casing (Bug#8254).
13174 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13175 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
13176 to use the following functions instead of these macros.
13177 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
13178 EMACS_INT, since callers assume the returned value fits in int.
13179 (upcase1): Likewise, for UPCASE_TABLE.
13180 (uppercasep, lowercasep, upcase): New static inline functions.
13181 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
13182 the race-condition problem in the old DOWNCASE.
13184 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):

13186 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
13187 (regex_compile, re_search_2, re_match_2_internal):
13188 Remove unused local vars.
13189 (FREE_VAR): Rewrite so as not to use empty "else",
13190 which gcc can warn about.
13191 (regex_compile, re_match_2_internal): Mark locals as initialized.
13192 (RETALLOC_IF): Define only if needed.
13193 (WORDCHAR_P): Likewise. This one is never needed, but is used
13194 only in a comment talking about a compiler bug, so put inside
13195 the #if 0 of that comment.
13196 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
13197 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
13198 Remove; unused.
13200 * search.c (boyer_moore): Rename locals to avoid shadowing.
13201 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
13202 (PREV_CHAR_BOUNDARY): Likewise.
13204 * search.c (simple_search): Remove unused var.
13206 * dired.c (compile_pattern): Move decl from here ...
13207 * lisp.h: ... to here, so that it can be checked.
13208 (struct re_registers): New forward decl.
13210 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
13212 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
13213 All uses changed.
13214 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
13215 Rename locals to avoid shadowing.
13216 (Fvertical_motion): Mark locals as initialized.
13218 * casefiddle.c (casify_object, casify_region): Now static.
13219 (casify_region): Mark local as initialized.
13221 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
13223 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
13224 New macros, so that the caller can use some names other than
13225 gcpro1, gcpro2, etc.
13226 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
13227 of the new macros.
13228 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
13229 argument, for consistency with GCPRO2_VAR, etc: it is now the
13230 prefix of the variable, not the variable itself. All uses
13231 changed.
13232 * dired.c (directory_files_internal, file_name_completion):
13233 Rename locals to avoid shadowing.
13235 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
13236 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
13237 dired.c's scmp function, had undefined behavior.
13238 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13239 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
13240 * buffer.h: ... to here, because these macros use current_buffer,
13241 and the new implementation with inline functions needs to have
13242 current_buffer in scope now, rather than later when the macros
13243 are used.
13244 (downcase, upcase1): New static inline functions.
13245 (DOWNCASE, UPCASE1): Reimplement using these functions.
13246 This avoids undefined behavior in expressions like
13247 DOWNCASE (x) == DOWNCASE (y), which previously suffered
13248 from race conditions in accessing the global variables
13249 case_temp1 and case_temp2.
13250 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
13251 * lisp.h (case_temp1, case_temp2): Remove their decls.
13252 * character.h (ASCII_CHAR_P): Move from here ...
