495 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
496 * nsterm.m (ns_term_init):
497 Avoid the need for strncpy, by using build_string or
498 make_unibyte_string directly. Use dtoastr, not snprintf.
499 * process.c (Fmake_network_process): Diagnose service names that
500 are too long, rather than silently truncating them or creating
501 non-null-terminated names.
502 (Fnetwork_interface_info): Likewise, for interface names.

531 Optimize pure C strings initialization.
532 * lisp.h (make_pure_string): Fix prototype.
533 (build_pure_c_string): New function, defined as static inline. This
534 provides a better opportunity to optimize away calls to strlen when
535 the function is called with compile-time constant argument.
536 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
537 argument, adjust users accordingly. Use build_pure_c_string where
538 appropriate.
539 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
540 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
541 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
543 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

554 srclen argument and return the length of result. Adjust users
555 accordingly.
556 (directory_file_name): Fix comment. Change to add srclen argument,
557 swap 1st and 2nd arguments to obey the common convention. Adjust
558 users accordingly.

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

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

584 2012-07-09 Glenn Morris <rgm@gnu.org>
586 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
587 since the included bsd-common.h does so.
589 Stop ns builds setting the EMACSPATH environment variable.
590 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
591 (ns_init_paths): Do not set EMACSPATH.
592 * nsterm.h (ns_exec_path): Add it.
593 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
594 Use ns_exec_path.
596 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
598 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
600 * process.c (wait_reading_process_output): 'waitchannels' was unset
601 when read_kbd || !NILP (wait_for_cell); fix this.

615 Add decls with ATTRIBUTE_CONST.
617 Minor improvements to make_formatted_string.
618 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
619 where int is good enough, as vsprintf returns an int.
620 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
622 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
624 Use make_formatted_string to avoid double length calculation.

649 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
651 Move marker debugging code under MARKER_DEBUG.
652 * marker.c (MARKER_DEBUG): Move marker debugging code under
653 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
654 for bootstrap with --enable-checking (~3x slowdown reported
655 by Juanma Barranquero <lekktu@gmail.com>).
656 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
658 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
660 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.

667 (display_line): Add commentary about displaying truncation glyphs
668 on GUI frames.
669 (produce_special_glyphs): Move here from term.c.
671 * term.c (produce_special_glyphs): Move to xdisp.c.
673 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
674 section.
676 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
678 * xdisp.c (display_line): Avoid warning about implicit declaration
679 of FRAME_FONT.
681 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
683 * lisp.h: Remove empty conditional.
685 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
687 * lread.c (load_path_check): Now static.
689 Fix some minor --with-ns problems found by static checking.
690 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
691 (x_set_font) [!HAVE_X_WINDOWS]:
692 * image.c (xpm_load_image) [HAVE_NS]:
693 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
694 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
695 Remove unused local.

697 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
698 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
699 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:

701 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
702 Fix pointer signedness problem.
703 * xfaces.c (FRAME_X_FONT_TABLE):
704 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
706 2012-07-07 Glenn Morris <rgm@gnu.org>
708 * lread.c (load_path_check): New function, split from init_lread.
709 (init_lread): Reorganize. Motivation:
710 If EMACSLOADPATH is set, check/warn about that rather than the
711 defaults, which we are not going to use. Hence we can remove
712 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
713 Don't warn if site-lisp directories are missing.
714 If not installed, start from a blank load-path, since
715 PATH_LOADSEARCH refers to the eventual installation directories.
717 2012-07-07 Eli Zaretskii <eliz@gnu.org>
719 Support truncation and continuation glyphs on GUI frames, when
720 fringes are disabled. (Bug#11832)
721 * xdisp.c (init_iterator): Get dimensions of truncation and
722 continuation glyphs even if on GUI frames. Adjust
723 it->last_visible_x on GUI frames when the left or right fringes,
724 or both, are absent.
725 (start_display, move_it_in_display_line_to): Handle the case of a
726 GUI frame without a fringe to display continuation or truncation
727 glyphs.
728 (insert_left_trunc_glyphs): Support GUI frames: make sure
729 truncation glyphs overwrite enough glyphs from the current line to
730 have sufficient space in pixels.
731 (display_line): Support truncation and continuation glyphs on GUI
732 frames. If some spare pixels are left on the line after inserting
733 the truncation glyphs, fill that space with a stretch glyph of a
734 suitably computed width.
736 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
737 produce_glyphs, to support GUI sessions.
739 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
741 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
743 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
745 Do not require float-time's arg to fit in time_t (Bug#11825).
746 This works better on hosts where time_t is unsigned, and where
747 float-time is applied to the (negative) difference between two times.
748 * editfns.c (decode_time_components): Last arg is now double *,
749 not int *, and means to store all the result as a double, without
750 worrying about whether the seconds part fits in time_t.
751 All callers changed.
752 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
753 All callers changed.
754 (Ffloat_time): Do not fail merely because the specified time falls
755 outside of time_t range.
757 2012-07-07 Glenn Morris <rgm@gnu.org>
759 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

765 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
766 Update dependencies.
768 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
770 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
772 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
773 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
774 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
775 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
776 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
777 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
779 * xfont.c (compare_font_names): Redo to omit the need for casts.
781 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
783 * xfns.c (Fx_change_window_property): Doc fix.
784 * w32fns.c (Fx_change_window_property): Doc fix.
786 * w32fns.c (Fx_window_property): Accept the same arguments as the
787 X Windows version. Doc fix.
788 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
790 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
791 Eli Zaretskii <eliz@gnu.org>
793 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
794 Windows-specific code from nt/config.nt moved here.
795 Obsolete settings removed.
797 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
799 * process.c: Avoid unnecessary calls to gettime.
800 (wait_reading_process_output): Don't get the time of day
801 when gobbling data immediately and not waiting, as there's no need
802 for it in that case. This removes a FIXME.
804 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
806 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
807 is defined (Bug#11768).
809 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
811 Fix marker debugging code.
812 * marker.c (byte_char_debug_check): Do not perform the check
813 if buffer is not multibyte.
814 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
815 Call byte_char_debug_check with correct arguments.
817 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
819 Compile marker debugging code only if ENABLE_CHECKING is defined.
820 * marker.c (byte_char_debug_check, count_markers):
821 Use only if ENABLE_CHECKING is defined.
822 (byte_debug_flag): Remove.
823 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
824 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
826 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
828 Avoid code repetition in marker-related functions.
829 * marker.c (attach_marker): New function.
830 (Fset_marker, set_marker_restricted, set_marker_both)
831 (set_marker_restricted_both): Use it.
832 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
833 Consistently rename charno to charpos.
834 (marker_position): Add eassert.
835 (marker_byte_position): Convert to eassert.
837 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

856 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
858 Do not use Fdelete_overlay in delete_all_overlays
859 to avoid redundant calls to unchain_overlay.
860 * buffer.c (drop_overlay): New function.
861 (delete_all_overlays, Fdelete_overlay): Use it.
862 * minibuf.c (get_minibuffer): Fix comment.
864 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
866 Port to OpenBSD 5.1 amd64.
867 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
868 This is needed for OpenBSD, and should be harmless on all BSD systems.
869 Also, include <sys/sysctl.h>, as it should be available on all
870 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
871 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
872 use p_pid member, not kp_proc.pid.
874 2012-07-06 Glenn Morris <rgm@gnu.org>
876 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
878 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
880 More xmalloc and related cleanup.
881 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
882 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
883 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:
884 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
885 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
886 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
887 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:

889 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
890 * xterm.c:
891 Omit needless casts involving void * pointers and allocation.
892 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
893 as the former is more robust if P's type is changed.
894 Prefer xzalloc to xmalloc + memset 0.
895 Simplify malloc-or-realloc to realloc.
896 Don't worry about xmalloc returning a null pointer.
897 Prefer xstrdup to xmalloc + strcpy.
898 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
899 growing it.
900 * keyboard.c (apply_modifiers_uncached): Prefer local array to
901 alloca of a constant.
903 2012-07-05 Eli Zaretskii <eliz@gnu.org>
905 * xdisp.c (display_line): Fix horizontal pixel coordinates when
906 hscroll is larger than the line width. Fixes long and futile
907 looping inside extend_face_to_end_of_line (on a TTY) producing
908 glyphs that are not needed and thrown away.
910 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

926 followed by gtk_box_set_homogeneous (Bug#11768).
927 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
928 (update_theme_scrollbar_width, xg_create_scroll_bar):
929 Use gtk_scrollbar_new (Bug#11768).
930 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
931 (is_box_type): New function (Bug#11768).
932 (xg_tool_item_stale_p): Call is_box_type.
933 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
934 with default display (Bug#11768).
936 2012-07-05 Eli Zaretskii <eliz@gnu.org>
938 * xdisp.c (window_hscroll_limited): New function.

1006 * fileio.c (time_error_value): Check the right error number.
1007 Problem reported by Troels Nielsen in
1008 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
1010 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1012 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
1013 This should be fixed in a better way; see Eli Zaretskii in
1014 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
1015 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
1017 * fileio.c (time_error_value): Rename from special_mtime.
1018 The old name's problems were noted by Eli Zaretskii in
1019 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
1021 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
1022 This variable's comment says Emacs needs at least one GDB-visible
1023 symbol of type enum pvec_type, to work around GDB problems.
1024 The symbol's value doesn't matter.
1026 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
1027 that causes compilation to fail on pre-C99 compilers.
1029 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
1031 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
1032 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
1034 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1036 * buffer.c (init_buffer_once): Fix initialization of
1037 headers for buffer_defaults and buffer_local_symbols.
1038 Reported by Juanma Barranquero <lekktu@gmail.com>.
1040 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
1042 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
1043 * lisp.h (enum pvec_type): Use fewer bits.
1044 (PSEUDOVECTOR_SIZE_BITS): New constant.
1045 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
1046 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
1047 change in pvec_type.
1048 (PSEUDOVECTOR_TYPEP): New macro.
1049 (TYPED_PSEUDOVECTORP): Use it.
1050 * fns.c (internal_equal): Adapt code to extract pvectype.
1051 * emacs.c (gdb_pvec_type): Update type.
1052 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
1053 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
1054 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
1055 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
1056 (sweep_vectors): Use it. Use local var `total_bytes' instead of
1057 abusing vector->header.next.nbytes.
1058 (live_vector_p): Use PVEC_TYPE.
1059 (mark_object): Adapt code to extract pvectype. Use switch.
1061 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1063 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
1064 Tighten new eassert a bit.
1066 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1068 Fix compilation with --enable-gcc-warnings and -O1
1069 optimization level.
1070 * doprnt.c (doprnt): Change type of tem to int, initialize
1071 to avoid compiler warning. Add eassert.
1072 * search.c (simple_search): Initialize match_byte to avoid
1073 compiler warning. Add eassert.
1075 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1077 Avoid weird behavior with large horizontal scrolls.
1078 Without this change, for example, large hscroll values would
1079 mess up Emacs's display on Fedora 15 x86, presumably due to
1080 overflows in int calculations in the display code.
1081 Also, if buffers had long lines, Emacs would freeze.
1082 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
1083 (set_window_hscroll): New function, containing the old guts of
1084 Fset_window_hscroll. Return the clipped value.
1085 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
1086 This avoids the need to check against PTRDIFF_MAX.
1088 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
1090 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1092 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
1094 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1096 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
1097 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
1098 since GCC 4.4.6 issues a bogus warning for them.
1100 Fix bugs in file timestamp newness comparisons.
1101 * fileio.c (Ffile_newer_than_file_p):
1102 * lread.c (Fload): Use full timestamp resolution of files,
1103 not just the 1-second resolution, so that files that are only
1104 slightly newer still count as newer.
1105 * fileio.c (Ffile_newer_than_file_p): Don't assume file
1106 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
1108 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
1110 * fileio.c: Improve handling of file time marker. (Bug#11852)
1111 (special_mtime): New function.
1112 (Finsert_file_contents, Fverify_visited_file_modtime):
1113 Use it to set special mtime values consistently.
1115 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
1117 * fileio.c (Finsert_file_contents): Properly handle st_mtime
1118 marker for non-existing file. (Bug#11852)
1120 2012-07-03 Glenn Morris <rgm@gnu.org>
1122 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
1123 and did not make it into globals.h).
1125 2012-07-03 Tom Tromey <tromey@redhat.com>
1127 * window.c (Fset_window_margins, Fset_window_fringes)
1128 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
1129 * textprop.c (Fprevious_property_change): No longer static.

1132 static.

1153 * fontset.h: Remove EXFUN.
1154 * font.h: Remove EXFUNs.
1155 * dosfns.c (system_process_attributes): Remove EXFUN.
1156 * keymap.h: Remove EXFUNs.
1157 * lisp.h: Remove EXFUNs.
1158 * w32term.h: Remove EXFUNs.
1159 * window.h: Remove EXFUNs.
1160 * xsettings.h: Remove EXFUN.
1161 * xterm.h: Remove EXFUN.
1163 2012-07-03 Glenn Morris <rgm@gnu.org>
1165 * lisp.h (Frandom): Make it visible to C.
1166 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
1167 buffer for invisible buffers. (Bug#1229)
1169 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1171 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
1172 values which aren't power of 2.
1173 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
1174 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
1175 accordingly.
1177 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
1179 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
1181 * alloc.c (mark_object): Revert part of last patch to use `switch'.
1183 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1185 * alloc.c (allocate_vector_block): Remove redundant
1186 calls to mallopt if DOUG_LEA_MALLOC is defined.
1187 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
1188 avoid calls to mallopt if zero_vector is returned.
1190 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1192 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
1193 is enabled, avoid dereferencing NULL current_sblock if
1194 running undumped.
1196 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1198 Cleanup basic buffer management.
1199 * buffer.h (struct buffer): Change layout to use generic vector
1200 marking code. Fix some comments. Change type of 'clip_changed'
1201 to bitfield. Remove unused #ifndef old.
1202 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
1203 (GET_OVERLAYS_AT): Fix indentation.
1204 (for_each_per_buffer_object_at): New macro.

1213 (mark_object): Use it. Adjust marking of misc objects
1214 and related comments.
1216 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
1218 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
1219 wrapper that is not needed because the wrapped code is a no-op (zero
1220 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
1221 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
1223 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
1225 * alloc.c (mark_buffer): Simplify. Remove prototype.
1226 (mark_object): Add comment. Reorganize marking of vector-like
1227 objects. Use CHECK_LIVE for all vector-like objects except buffers
1228 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
1229 redundant calls to mark_vectorlike for bool vectors.
1231 2012-06-30 Glenn Morris <rgm@gnu.org>
1233 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
1235 * epaths.in (PATH_SITELOADSEARCH): New.
1236 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
1237 This is rather than relying on --enable-locallisppath elements
1238 having "site-lisp" in their names. (Bug#10208#25, 11658)
1240 2012-06-30 Eli Zaretskii <eliz@gnu.org>
1242 * w32proc.c (sys_select): Accept and ignore one more argument.
1244 * w32.c (emacs_gnutls_pull): Call select with one more argument.
1246 * sysselect.h [DOS_NT]: Don't include sys/select.h.
1247 (pselect) [!MS_DOS]: Redirect to sys_select.
1249 * sysdep.c: Don't include dos.h and dosfns.h.
1251 * process.c (sys_select):
1252 * msdos.c (sys_select): Accept one more argument and ignore it.
1254 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
1255 adapt data types and code to that.
1257 * dosfns.c:
1258 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
1259 which clashes with the gnulib function of the same name.
1261 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
1263 * font.c (font_style_to_value, font_style_symbolic)
1264 (font_prop_validate_style): Add type checks for values in
1265 font_style_table.
1267 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
1268 argument.
1269 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
1270 uses.
1272 2012-06-29 Eli Zaretskii <eliz@gnu.org>
1274 * xdisp.c (try_window_id): Undo last change.
1276 * w32.c (getwd): Adjust commentary about startup_dir.
1277 (init_environment): Always call sys_access, even in non-MSVC
1278 builds. Don't chdir to the directory of the Emacs executable.
1279 This undoes code from 1997 which was justified by the need to
1280 "avoid conflicts when removing and renaming directories". But its
1281 downside was that every relative file name was being interpreted
1282 relative to the directory of the Emacs executable, which can never
1283 be TRT. In particular, it broke sys_access when called with
1284 relative file names.
1285 (sys_access): Map GetLastError to errno.
1287 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1289 * window.h (struct window): Change type of 'fringes_outside_margins'
1290 to bitfield. Fix comment. Adjust users accordingly.

1292 Adjust comment.
1293 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
1294 to ptrdiff_t.
1296 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
1298 * gnutls.c (emacs_gnutls_handshake):
1299 Add QUIT to make the loop interruptible.
1301 2012-06-29 Glenn Morris <rgm@gnu.org>
1303 * charset.c (init_charset): Make lack of etc/charsets fatal.
1305 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1307 * editfns.c (region_limit): Fix type mismatch.
1309 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1311 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
1312 undefined. Convert from xassert to eassert.
1313 * nsmenu.m: Convert from xassert to eassert.
1314 * nsterm.m: Likewise.
1316 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
1318 * editfns.c (region_limit): Clip to narrowing (bug#11770).
1320 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
1322 Avoid integer overflow on scroll-left and scroll-right.
1323 * window.c (HSCROLL_MAX): New macro.
1324 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
1325 overflow when requested scroll falls outside ptrdiff_t range.
1327 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
1329 * window.h (struct window): Change type of 'hscroll',
1330 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
1331 'last_modified' and 'last_overlay_modified' to EMACS_INT.
1332 Adjust users accordingly.
1333 * xdisp.c (try_cursor_movement): Replace type check with eassert.
1334 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
1335 from EMACS_INT to ptrdiff_t.
1336 (make_window): Omit redundant initialization.
1338 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
1340 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
1342 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
1344 * window.h (struct window): Change type of 'use_time' and
1345 'sequence_number' from Lisp_Object to int.

1353 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
1354 enabled with --enable-checking=[all,glyphs] configure option.
1355 Fix GLYPH_DEBUG usage assuming that it may be undefined,
1356 adjust comments accordingly.
1357 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
1358 undefined, adjust comments accordingly.

1370 Generalize run-time debugging checks.

1469 * alloc.c: Remove build_string.
1470 * lisp.h: Define build_string as static inline. This provides

1477 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
1479 Use sprintf return value instead of invoking strlen on result.
1480 In the old days this wasn't portable, since some sprintf
1481 implementations returned char *. But they died out years ago and
1482 Emacs already assumes sprintf returns int.
1483 Similarly for float_to_string.
1484 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
1485 * ccl.c (ccl_driver):

1490 * xdisp.c (message_dolog):
1491 * xfns.c (syms_of_xfns):
1492 Use sprintf or float_to_string result to avoid need to call strlen.
1493 * data.c (Fnumber_to_string):
1494 Use make_unibyte_string, since the string must be ASCII.
1495 * lisp.h, print.c (float_to_string): Now returns int length.
1496 * term.c (produce_glyphless_glyph):
1497 Use sprintf result rather than recomputing it.
1499 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
1500 * Makefile.in (ALL_CFLAGS):
1501 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

1526 sprintf already null-terminates its output.
1528 * xfns.c (x_window): Remove redundant cast.
1530 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
1532 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
1533 `const char *' to `char *' to avoid compiler warning.
1535 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
1537 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
1538 instead of truncating it to 63 (admittedly a generous limit).
1540 * process.c: Fix spelling and caps in comments.

1593 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
1595 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
1596 * lisp.h (WAIT_READING_MAX): New macro.
1597 * dispnew.c (Fsleep_for, sit_for):
1598 * keyboard.c (kbd_buffer_get_event):
1599 * process.c (Faccept_process_output):
1600 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
1601 This improves on the previous patch, which introduced a bug
1602 when time_t is unsigned and as wide as intmax_t.
1603 See <http://bugs.gnu.org/9000#51>.
1605 2012-06-23 Eli Zaretskii <eliz@gnu.org>
1607 * dispnew.c (sit_for, Fsleep_for):
1608 * keyboard.c (kbd_buffer_get_event):

1622 Privately reported by Herbert J. Skuhra.
1623 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
1624 All uses changed.
1625 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
1626 not make_lisp_timeval, when the argument is of type EMACS_TIME.
1628 2012-06-23 Eli Zaretskii <eliz@gnu.org>
1630 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
1631 last argument of make_unibyte_string.
1633 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
1634 language ID in the event parameters.
1636 * w32term.c (w32_read_socket): Put the new keyboard codepage into
1637 event.code, not the obscure "character set ID".
1639 2012-06-23 Chong Yidong <cyd@gnu.org>
1641 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

1660 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
1661 Privately reported by Herbert J. Skuhra.
1662 [__FreeBSD__]: Remove "*/" typo after "#include".
1663 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
1664 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.

1668 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
1670 Support higher-resolution time stamps (Bug#9000).
1671 The time stamps are only nanosecond-resolution at the C level,
1672 since that's the best that any real-world system supports now.
1673 But they are picosecond-resolution at the Lisp level, as that's
1674 easy, and leaves room for future OS improvements.
1676 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
1677 (LIBES): Use it.
1679 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
1680 Don't get current time unless it's needed.
1682 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
1683 now provides it if it's absent.
1684 (start_atimer): Port to higher-res time stamps.
1685 Check for time stamp overflow. Don't get current time more
1686 often than is needed.
1688 * buffer.h (struct buffer): Buffer modtime now has high resolution.
1689 Include systime.h, not time.h.
1690 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
1692 * dired.c: Include stat-time.h.
1693 (Ffile-attributes): File times now have higher resolution.
1695 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
1696 (struct image): Timestamp now has higher resolution.
1698 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
1699 has at least microseconds now. All uses removed.
1700 (update_frame, update_single_window, update_window, update_frame_1)
1701 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
1703 * editfns.c (time_overflow): Now extern.
1704 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
1705 (float-time, Fformat_time_string, Fcurrent_time_string)
1706 (Fcurrent_time_zone): Accept and generate higher-resolution
1707 time stamps.
1708 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
1709 (decode_time_components, lisp_seconds_argument): New functions.
1710 (make_time): Now static.
1711 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
1712 Report an error if the time is invalid, rather than having the caller
1713 do that.
1715 * fileio.c: Include <stat-time.h>
1716 (Fcopy_file): Copy higher-resolution time stamps.
1717 Prefer to set the time stamp via a file descriptor if that works.
1718 (Fset_file_times, Finsert_file_contents, Fwrite_region)
1719 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
1720 (Fvisited_file_modtime, Fset_visited_file_modtime):
1721 Support higher-resolution time stamps.
1723 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
1725 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
1727 * image.c (prepare_image_for_display, clear_image_cache)
1728 (lookup_image): Port to higer-resolution time stamps.
1730 * keyboard.c (start_polling, bind_polling_period):
1731 Check for time stamp overflow.
1732 (read_char, kbd_buffer_get_event, timer_start_idle)
1733 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
1734 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
1735 Port to higher-resolution time stamps. Do not assume time_t is signed.
1736 (decode_timer): New function. Timers are now vectors of length 9,
1737 not 8, to accommodate the picosecond component.
1738 (timer_check_2): Use it.
1740 * nsterm.m (select_timeout, timeval_subtract): Remove.
1741 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
1742 as they're a bit more accurate and handle overflow better.
1743 (ns_select): Change prototype to be compatible with pselect.
1744 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
1745 * nsterm.h (ns_select): Adjust prototype.
1747 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
1748 us-resolution time stamps.
1749 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
1751 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
1753 * lisp.h (time_overflow): New decl.
1754 (wait_reading_process_output): First arg is now intmax_t, not int,
1755 to accommodate larger waits.
1757 * process.h (struct Lisp_Process.read_output_delay):
1758 Now counts nanoseconds, not microseconds.
1759 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
1760 EMACS_HAS_USECS.
1761 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
1762 (wait_reading_process_output):
1763 Port to ns-resolution time stamps.
1764 (Faccept_process_output, wait_reading_process_output):
1765 Check for time stamp overflow. Do not assume time_t is signed.
1766 (select_wrapper): Remove; we now use pselect.
1767 (Fprocess_attributes): Now generates ns-resolution time stamps.
1769 * sysdep.c: Include utimens.h. Don't include utime.h
1770 or worry about struct utimbuf; gnulib does that for us now.
1771 (gettimeofday): Remove; gnulib provides a substitute.
1772 (make_timeval): New function.
1773 (set_file_times): Now sets ns-resolution time stamps.
1774 New arg FD; all uses changed.
1775 (time_from_jiffies, ltime_from_jiffies, get_up_time)
1776 (system_process_attributes):
1777 Now returns ns-resolution time stamp. All uses changed.
1778 Check for time stamp overflow.
1780 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
1781 provides a substitute now.
1783 * systime.h: Include timespec.h rather than sys/time.h and time.h,
1784 since it guarantees struct timespec.
1785 (EMACS_TIME): Now struct timespec, so that we can support
1786 ns-resolution time stamps.
1787 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
1788 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
1789 (EMACS_USECS): Remove.
1790 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
1791 so multiply the arg by 1000 before storing it.
1792 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
1793 New macros.
1794 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
1795 Port to ns-resolution time stamps.
1796 (EMACS_TIME_NEG_P): Remove; replaced by....
1797 (EMACS_TIME_SIGN): New macro.
1798 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
1799 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

1801 (make_timeval, make_lisp_time, decode_time_components): New decls.
1802 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
1803 that it mishandled time_t overflow. You can't compare by subtracting!
1804 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
1805 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
1807 * term.c: Include <sys/time.h>.
1808 (timeval_to_Time): New function, for proper overflow wraparound.
1809 (term_mouse_position, term_mouse_click): Use it.
1811 * undo.c (record_first_change): Support higher-resolution time stamps
1812 in the undo buffer.
1813 (Fprimitive_undo): Use them when restoring time stamps.
1815 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
1816 (w32_get_internal_run_time):
1817 Port to higher-resolution Emacs time stamps.
1818 (ltime): Now accepts single 64-bit integer, as that's more convenient
1819 for callers.
1821 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
1823 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
1824 for compatibility with pselect. Support ns-resolution time stamps.
1826 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
1828 * xselect.c (wait_for_property_change, x_get_foreign_selection):
1829 Check for time stamp overflow, and support ns-resolution time stamps.
1831 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
1832 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
1833 (timeval_subtract): Remove; no longer needed.
1834 (XTflash, XTring_bell, x_wait_for_event):
1835 Port to ns-resolution time stamps. Don't assume time_t is signed.
1837 2012-06-22 Chong Yidong <cyd@gnu.org>
1839 * xdisp.c (x_consider_frame_title): Revert last change.
1841 2012-06-22 Eli Zaretskii <eliz@gnu.org>
1843 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
1844 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
1845 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
1846 staticidx goes up to 1597 out of 1600 = 0x640.)
1848 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
1850 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
1851 Otherwise, the umask might be mistakenly 0 while handling input signals.
1853 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>

1872 (unwind_format_mode_line): Restore them.
1873 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
1874 Callers changed.
1875 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
1876 since tty frames can be explicitly named.
1877 (prepare_menu_bars): Likewise.
1879 * term.c (Ftty_top_frame): New function.
1881 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
1883 Port byte-code-meter to modern targets.
1884 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
1885 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
1886 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
1887 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
1888 (METER_1, METER_2): Simplify.

1897 gets killed during executing of this function (Bug#11665).
1898 Try to always return Qt when the buffer has been actually killed.
1899 (Vkill_buffer_query_functions): In doc-string say that functions
1900 run by this hook should not change the current buffer.

1928 its argument.
1930 * coding.c (produce_chars): Use ptrdiff_t, not int.
1932 * xterm.c (x_draw_underwave): Check for integer overflow.
1933 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

2024 2012-06-16 Eli Zaretskii <eliz@gnu.org>
2026 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
2027 If all the glyphs of the glyph row came from strings, and we have no
2028 cursor positioning clues, put the cursor on the first glyph of the
2029 row.
2030 (handle_face_prop): Use chunk-relative overlay string index when
2031 indexing into it->string_overlays array. (Bug#11653)

2049 * .gdbinit (xgetint): Fix recently-introduced paren typo.
2050 Assume USE_2_TAGS_FOR_INTS.

2076 * lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct
2077 instead of union.

2106 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
2107 * alloc.c (make_number) [!defined make_number]:

2119 as the union type is for debugging, not for production.
2120 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
2121 Use an inline function on all platforms when using the union type,
2122 since this is simpler and 'static inline' can be used portably
2123 within Emacs now.
2124 (LISP_INITIALLY_ZERO): New macro.
2125 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.

2213 2012-06-08 Eli Zaretskii <eliz@gnu.org>
2215 * dispnew.c (showing_window_margins_p): Undo last change, which

2229 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
2231 2012-06-08 Eli Zaretskii <eliz@gnu.org>
2233 * alloc.c (allocate_vectorlike): Fix last change.
2235 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
2237 Block-based vector allocation of small vectors.

2256 or equal to VBLOCK_BYTES_MAX.
2257 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
2258 (init_alloc_once): Add call to init_vectors.
2260 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
2262 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
2264 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
2266 * doprnt.c (doprnt): Truncate multibyte char correctly.
2267 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
2268 would mishandle a string argument "Xc" if X was a multibyte
2269 character of length 2: it would truncate after X's first byte
2270 rather than including all of X.
2272 2012-06-06 Chong Yidong <cyd@gnu.org>
2274 * buffer.c (word_wrap): Doc fix.

2316 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
2317 and DEFVAR it. Update all users.
2319 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
2321 * minibuf.c (Fassoc_string): Remove duplicate declaration.
2323 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
2324 Convert pctcpu and pctmem to Lisp float properly.
2325 Let the compiler fold better, as 100.0/0x8000 is exact.
2327 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
2329 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
2330 cons_block.
2332 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
2334 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
2336 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
2338 For a 'struct window', replace some Lisp_Object fields to
2339 bitfields where appropriate, remove unused fields.
2340 * window.h (struct window): Remove unused 'last_mark_x' and
2341 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
2342 change it's type from Lisp_Object to bitfield.
2343 Change type of 'force_start', 'optional_new_start',
2344 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
2345 fields from Lisp_Object to bitfield. Adjust users accordingly.
2347 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2349 Pacify gcc -Wdouble-precision when using Xaw.
2350 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
2351 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
2352 Use 'float' consistently, rather than 'float' in most places
2353 and 'double' in a couple of places.
2355 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2357 * xdisp.c (handle_stop): Detect whether we have overlay strings
2358 loaded by testing it->current.overlay_string_index to be
2359 non-negative, instead of checking whether n_overlay_strings is
2360 positive. (Bug#11587)
2362 2012-05-31 Chong Yidong <cyd@gnu.org>
2364 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
2366 * doc.c (Fsubstitute_command_keys): Doc fix.
2368 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2370 * search.c (search_buffer): Remove calls to
2371 r_alloc_inhibit_buffer_relocation, as it is now called by
2372 maybe_unify_char, which was the cause of relocation of buffer text
2373 in bug#11519.
2375 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2377 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
2378 for the duration of call to load_charset, to avoid problems with
2379 callers of maybe_unify_char that access buffer text through C
2380 pointers.
2382 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
2383 decrement the inhibition flag, instead of just setting or
2384 resetting it.
2386 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2388 Remove obsolete '#define static' cruft.
2389 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
2390 This #undef was "temporary" in 2000; it is no longer needed
2391 now that '#define static' has gone away.
2392 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
2393 (gray_bitmap_bits): Remove; no longer needed.
2394 All uses replaced with definiens.
2395 * xterm.c: Include "bitmaps/gray.xbm".
2397 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
2399 Clean up __executable_start, monstartup when --enable-profiling.
2400 The following changes affect the code only when profiling.
2401 * dispnew.c (__executable_start): Rename from safe_bcopy.
2402 Define only on platforms that need it.
2403 * emacs.c: Include <sys/gmon.h> when profiling.
2404 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
2405 (__executable_start): Remove decl, since lisp.h does it now.
2406 (safe_bcopy): Remove decl; no longer has that name.
2407 (main): Coalesce #if into single bit of code, for simplicity.
2408 Cast pointers to uintptr_t, since standard libraries want integers
2409 and not pointers.
2410 * lisp.h (__executable_start): New decl.
2412 2012-05-31 Glenn Morris <rgm@gnu.org>
2414 * image.c (Fimagemagick_types): Doc fix.
2416 2012-05-30 Jim Meyering <meyering@redhat.com>
2418 * callproc.c (Fcall_process_region): Include directory component
2419 in mkstemp error message (Bug#11586).
2421 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
2423 * alloc.c, lisp.h (make_pure_vector): Now static.
2425 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
2427 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
2428 Move to byte-run.el.
2429 (Fautoload): Do the hash-doc more carefully.
2430 * data.c (Fdefalias): Purify definition, except for keymaps.
2431 (Qdefun): Move from eval.c.
2432 * lisp.h (Qdefun): Remove.
2433 * lread.c (read1): Tiny simplification.
2435 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
2437 Do not create empty overlays with the evaporate property (Bug#9642).
2438 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
2439 Bug#9642, but explicitly check that the buffer the overlay would
2440 be moved to is live and rearrange lines to make sure that errors
2441 will not put the overlay in an inconsistent state.
2442 (Fdelete_overlay): Cosmetics.
2444 2012-05-28 Eli Zaretskii <eliz@gnu.org>
2446 * w32term.c (my_bring_window_to_top): New function.
2447 (x_raise_frame): Use handle returned by DeferWindowPos, which
2448 could be different from the original one.
2449 Call my_bring_window_to_top instead of my_set_foreground_window.
2450 (Bug#11513)
2452 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
2453 by calling BringWindowToTop.
2455 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
2456 (WM_EMACS_END): Increase by one.
2458 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
2460 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
2461 This avoids undefined behavior that might cause the eassert
2462 to not catch an out-of-range value.
2464 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
2466 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
2467 Update dependencies.
2469 2012-05-27 Eli Zaretskii <eliz@gnu.org>
2471 * bidi.c (bidi_mirror_char): Fix last change.
2473 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
2475 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
2476 when referring to sectname field in printf format.
2478 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
2480 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
2481 Only r_alloc_inhibit_buffer_relocation needed to be added;
2482 the others were already declared.
2484 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
2485 before checking whether it's out of range. Put the check inside
2486 eassert. See
2487 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
2489 2012-05-27 Ken Brown <kbrown@cornell.edu>
2491 * callproc.c (Fcall_process): Restore a line that was accidentally
2492 commented out in the 2011-02-13 change (bug#11547).
2494 2012-05-27 Eli Zaretskii <eliz@gnu.org>
2496 * lisp.h [REL_ALLOC]: Add prototypes for external functions
2497 defined on ralloc.c.
2499 * buffer.c [REL_ALLOC]: Remove prototypes of
2500 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
2501 they are now on lisp.h.
2503 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
2505 * search.c (search_buffer): Use it to inhibit relocation of buffer
2506 text while re_search_2 is doing its job, because re_search_2 is
2507 passed C pointers to buffer text. (Bug#11519)
2509 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
2510 Update value to 24.
2512 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
2513 state after an additional call to move_it_in_display_line_to, keep
2514 the values of it->max_ascent and it->max_descent found for the
2515 entire line.
2516 (pos_visible_p): Revert the comparison against bottom_y to what it
2517 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
2518 (Bug#11464)
2520 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
2522 Fix coding-related core dumps with gcc -ftrapv.
2523 The code was computing A - B, where A and B are pointers, and B is
2524 random garbage. This can lead to core dumps on platforms that
2525 have special pointer registers, and it also leads to core dumps on
2526 x86-64 when compiled with gcc -ftrapv. The fix is to compute
2527 A - B only when B is initialized properly.
2528 * coding.c (coding_set_source, coding_set_destination): Return void.
2529 (coding_change_source, coding_change_destinations): New functions,
2530 with the old behaviors of coding_set_source and coding_set_destination.
2531 All callers that need an offset changed to use these new functions.
2533 2012-05-26 Glenn Morris <rgm@gnu.org>
2535 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
2537 2012-05-26 Eli Zaretskii <eliz@gnu.org>
2539 Extend mouse support on W32 text-mode console.
2540 * xdisp.c (draw_row_with_mouse_face):
2541 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
2543 * w32console.c: Include window.h.
2544 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
2545 New functions.
2546 (initialize_w32_display): Initialize mouse-highlight data.
2548 * w32inevt.c: Include termchar.h and window.h.
2549 (do_mouse_event): Support mouse-autoselect-window. When the mouse
2550 moves, call note_mouse_highlight. If help_echo changed, call
2551 gen_help_event to produce help-echo message in the echo area.
2552 Call clear_mouse_face if mouse_face_hidden is set in the mouse
2553 highlight info.
2555 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
2557 * lread.c (read1): Simplify slightly to avoid an overflow warning
2558 with GCC 4.7.0 on x86-64.
2560 2012-05-26 Eli Zaretskii <eliz@gnu.org>
2562 * bidi.c (bidi_mirror_char): Revert last change: an int is
2563 definitely wide enough here.
2565 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
2567 Fix integer width and related bugs (Bug#9874).
2568 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
2569 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
2570 (string_bytes, check_sblock, allocate_string_data):
2571 (compact_small_strings, Fmake_bool_vector, make_string)
2572 (make_unibyte_string, make_multibyte_string)
2573 (make_string_from_bytes, make_specified_string)
2574 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
2575 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
2576 (mark_vectorlike):
2577 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2578 (allocate_pseudovector):
2579 Use int, not EMACS_INT, where int is wide enough.
2580 (inhibit_garbage_collection, Fgarbage_collect):
2581 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2582 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
2583 int might not be wide enough.
2584 (bidi_cache_search, bidi_cache_find, bidi_init_it)
2585 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2586 (bidi_at_paragraph_end, bidi_find_paragraph_start)
2587 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
2588 (bidi_level_of_next_char, bidi_move_to_visually_next):
2589 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2590 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
2591 (Fkill_buffer, Fset_buffer_major_mode)
2592 (advance_to_char_boundary, Fbuffer_swap_text)
2593 (Fset_buffer_multibyte, overlays_at, overlays_in)
2594 (overlay_touches_p, struct sortvec, record_overlay_string)
2595 (overlay_strings, recenter_overlay_lists)
2596 (adjust_overlays_for_insert, adjust_overlays_for_delete)
2597 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
2598 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
2599 (Foverlay_recenter, last_overlay_modification_hooks_used)
2600 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
2601 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2602 (validate_region): Omit unnecessary test for b <= e,
2603 since that's guaranteed by the previous test.
2604 (adjust_overlays_for_delete): Avoid pos + length overflow.
2605 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
2606 (report_overlay_modification):
2607 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2608 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
2609 Omit pointer cast, which isn't needed anyway, and doesn't work
2610 after the EMACS_INT -> ptrdiff_t change.
2611 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
2612 * buffer.h: Adjust decls to match defn changes elsewhere.
2613 (struct buffer_text, struct buffer):
2614 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2615 Use EMACS_INT, not int, where int might not be wide enough.
2616 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
2617 not int, to avoid needless 32-bit limit on 64-bit hosts.
2618 (exec_byte_code): Use tighter memory-full test, one that checks
2619 for alloca overflow. Don't compute the address of the object just
2620 before an array, as that's not portable. Use EMACS_INT, not
2621 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
2622 * callint.c (Fcall_interactively):
2623 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2624 * callproc.c (call_process_kill, Fcall_process):
2625 Don't assume pid_t fits into an Emacs fixnum.
2626 (call_process_cleanup, Fcall_process, child_setup):
2627 Don't assume pid_t fits into int.
2628 (call_process_cleanup, Fcall_process, delete_temp_file)
2629 (Fcall_process_region):
2630 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2631 (Fcall_process): Simplify handling of volatile integers.
2632 Use int, not EMACS_INT, where int will do.
2633 * casefiddle.c (casify_object, casify_region, operate_on_word)
2634 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
2635 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2636 (casify_object): Avoid integer overflow when overallocating buffer.
2637 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
2638 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
2639 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
2640 * category.h (CATEGORYP): Don't assume arg is nonnegative.
2641 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
2642 integers are now checked earlier. All uses replaced with XINT.
2643 (ccl_driver):
2644 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2645 For CCL_MapSingle, check that content and value are in int range.
2646 (ccl_driver, Fregister_code_conversion_map):
2647 Check that Vcode_version_map_vector is a vector.
2648 (resolve_symbol_ccl_program): Check that vector header is in range.
2649 Always copy the vector, so that we can check its contents reliably
2650 now rather than having to recheck each instruction as it's being
2651 executed. Check that vector words fit in 'int'.
2652 (ccl_get_compiled_code, Fregister_ccl_program)
2653 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
2654 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
2655 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
2656 contents are in range.
2657 (Fccl_execute_on_string): Check that status is in range.
2658 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
2659 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
2660 Accept and return EMACS_INT, not int, because callers can pass values
2661 out of 'int' range.
2662 (c_string_width, strwidth, lisp_string_width, chars_in_text)
2663 (multibyte_chars_in_text, parse_str_as_multibyte)
2664 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
2665 (str_as_unibyte, str_to_unibyte, string_count_byte8)
2666 (string_escape_byte8, Fget_byte):
2667 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2668 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
2669 avoid mishandling large integers.
2670 * character.h: Adjust decls to match defn changes elsewhere.
2671 * charset.c (load_charset_map_from_file, find_charsets_in_text)
2672 (Ffind_charset_region):
2673 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2674 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
2675 (load_charset_map_from_vector, Fdefine_charset_internal):
2676 Don't assume fixnum fits in int.
2677 (load_charset_map_from_vector, Fmap_charset_chars):
2678 Remove now-unnecessary CHECK_NATNUMs.
2679 (Fdefine_charset_internal): Check ranges here, more carefully.
2680 Don't rely on undefined behavior with signed left shift overflow.
2681 Don't assume unsigned int fits into fixnum, or that fixnum fits
2682 into unsigned int. Don't require max_code to be a valid fixnum;
2683 that's not true for gb10830 4-byte on a 32-bit host. Allow
2684 invalid_code to be a cons, for the same reason. Require code_offset
2685 to be a character. Avoid int overflow if max_char is close
2686 to INT_MAX.
2687 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
2688 this is intended anyway and avoids some undefined behavior.
2689 (load_charset_map): Pass unsigned, not int, as 2nd arg of
2690 INDEX_TO_CODE_POINT, as that's what it expects.
2691 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
2692 * charset.h (DECODE_CHAR): Return int, not unsigned;
2693 this is what was intended anyway, and it avoids undefined behavior.
2694 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
2695 integer-overflow issues.
2696 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
2697 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
2698 where the argument is EMACS_INT, and this behavior is not intended.
2699 * chartab.c (Fmake_char_table, Fset_char_table_range)
2700 (uniprop_get_decoder, uniprop_get_encoder):
2701 Don't assume fixnum fits in int.
2702 * cmds.c (move_point): New function, that does the gist of
2703 Fforward_char and Fbackward_char, but does so while checking
2704 for integer overflow more accurately.
2705 (Fforward_char, Fbackward_char): Use it.
2706 (Fforward_line, Fend_of_line, internal_self_insert)
2707 (internal_self_insert):
2708 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2709 Fix a FIXME, by checking for integer overflow when calculating
2710 target_clm and actual_clm.
2711 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)

3425 Assume C89 or later.
3426 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
3427 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
3428 (xrealloc):
3429 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
3430 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
3431 * textprop.c, tparam.c (NULL): Remove.
3432 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
3433 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
3434 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
3435 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
3436 * xterm.c (input_signal_count): Assume volatile works.
3438 2012-05-21 Ken Brown <kbrown@cornell.edu>
3440 * xgselect.c (xg_select): Fix first argument in call to 'select'
3441 (bug#11508).
3443 2012-05-20 Ken Brown <kbrown@cornell.edu>
3445 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
3446 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
3448 2012-05-19 Ken Brown <kbrown@cornell.edu>
3450 * xfns.c (x_in_use): Remove `static' qualifier.
3451 * xterm.h (x_in_use): Declare.
3452 * xgselect.c: Include xterm.h.
3453 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
3454 and `display_arg' (bug#9754).
3456 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
3458 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
3460 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
3461 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
3463 2012-05-18 Eli Zaretskii <eliz@gnu.org>
3465 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
3467 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
3468 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
3470 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
3471 reference to image_cache->refcount.
3472 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
3474 2012-05-17 Juri Linkov <juri@jurta.org>
3476 * search.c (Fword_search_regexp, Fword_search_backward)
3477 (Fword_search_forward, Fword_search_backward_lax)
3478 (Fword_search_forward_lax): Move functions to isearch.el
3479 (bug#10145, bug#11381).
3481 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
3483 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
3485 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
3487 * lread.c (init_obarray): Declare Qt and Qnil as special.
3489 2012-05-14 Glenn Morris <rgm@gnu.org>
3491 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
3492 Put "libexec" before "bin", for the sake of init_callproc_1.
3494 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3496 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
3498 * unexaix.c: Port to more-recent AIX compilers.
3499 (report_error, report_error_1, make_hdr, copy_sym)
3500 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
3501 Make arguments const char *, not char *, to avoid violations of C
3502 standard and to fix some AIX warnings reported by Gilles Pion.
3504 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3506 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
3507 already have overlays loaded.
3508 (handle_single_display_spec): Before returning without displaying
3509 fringe bitmap, synchronize the bidi iterator with the main display
3510 iterator, by calling iterate_out_of_display_property.
3511 (iterate_out_of_display_property): Detect buffer iteration by
3512 testing that it->string is a Lisp string.
3513 (get_next_display_element): When the current object is exhausted,
3514 and there's something on it->stack, call set_iterator_to_next to
3515 proceed with what's on the stack, instead of returning zero.
3516 (set_iterator_to_next): If called at the end of a Lisp string,
3517 proceed to consider_string_end without incrementing string
3518 position. Don't increment display vector index past the end of
3519 the display vector. (Bug#11417)
3520 (pos_visible_p): Don't report a position visible when move_it_to
3521 stopped at the last line of window, which happens to be scanned
3522 backwards by the bidi iteration. (Bug#11464)
3524 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3526 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
3527 and right-margin display specs even if the spec is invalid or we
3528 are on a TTY, and thus unable to display on the fringes.
3529 That's because the text with the property will not be displayed anyway,
3530 so we need to signal to the caller that this is a "replacing"
3531 display spec. This fixes display when the spec is invalid or we
3532 are on a TTY.
3534 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3536 * unexaix.c (make_hdr): Fix typo in prototype.
3537 This bug broke the build on AIX. Problem reported by Gilles Pion.
3539 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
3541 * keyboard.c (kbd_buffer_get_event): Read special events also in
3542 batch mode. (Bug#11415)
3544 2012-05-12 Glenn Morris <rgm@gnu.org>
3546 * ns.mk: Update for ns_appbindir no longer having trailing "/".
3548 2012-05-12 Eli Zaretskii <eliz@gnu.org>
3550 * lisp.mk (lisp): Add newcomment.elc.
3552 2012-05-12 Glenn Morris <rgm@gnu.org>
3554 * Makefile.in (MKDIR_P): New, set by configure.
3555 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
3557 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
3559 Remove unused function hourglass_started.
3560 * dispextern.h (hourglass_started):
3561 * w32fns.c (hourglass_started):
3562 * xdisp.c (hourglass_started): Remove.
3564 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
3566 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
3567 Update dependencies.
3569 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
3571 * xgselect.c (xg_select): Put maxfds+1 into a var.
3572 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
3574 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
3576 2012-05-10 Dave Abrahams <dave@boostpro.com>
3578 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
3579 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
3581 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
3583 * dbusbind.c (xd_registered_buses): New internal Lisp object.
3584 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
3585 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
3586 Initialize xd_registered_buses.
3588 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
3590 Untag more efficiently if USE_LSB_TAG.
3591 This is based on a proposal by YAMAMOTO Mitsuharu in
3592 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
3593 For an admittedly artificial (nth 8000 longlist) benchmark on
3594 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
3595 Emacs's overall text size by 1%.
3596 * lisp.h (XUNTAG): New macro.
3597 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
3598 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
3599 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
3600 * eval.c (Fautoload):
3601 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
3602 * frame.h (XFRAME): Use XUNTAG.
3604 Port recent dbusbind.c changes to 32-bit --with-wide-int.
3605 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
3606 Remove unportable assumptions about print widths of types like
3607 dbus_uint32_t.
3608 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
3609 intptr_t when converting between pointer and integer, to avoid GCC
3610 warnings about wrong width.
3612 2012-05-09 Eli Zaretskii <eliz@gnu.org>
3614 * w32proc.c (new_child): Force Windows to reserve only 64KB of
3615 stack for each reader_thread, instead of defaulting to 8MB
3616 determined by the linker. This avoids failures in creating
3617 subprocesses on Windows 7, see the discussion in this thread:
3618 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
3620 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
3622 Fix up display of the *Minibuf-0* buffer in the mini window.
3623 * keyboard.c (read_char): Don't clear the echo area if there's no
3624 message to clear.
3625 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
3626 contents of *Minibuf-0*) if there's no message displayed in its stead.
3628 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
3630 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
3631 batch mode.
3633 2012-05-06 Chong Yidong <cyd@gnu.org>
3635 * lisp.mk (lisp): Update.
3637 2012-05-05 Jim Meyering <meyering@redhat.com>
3639 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
3641 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
3643 * data.c (PUT_ERROR): New macro.
3644 (syms_of_data): Use it. Add new error type `user-error'.
3645 * undo.c (user_error): New function.
3646 (Fprimitive_undo): Use it.
3647 * print.c (print_error_message): Adjust print style for `user-error'.
3648 * keyboard.c (user_error): New function.
3649 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
3651 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
3653 Do not limit current-time-string to years 1000..9999.
3654 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
3655 (Fcurrent_time_string): Support any year that is supported by the
3656 underlying localtime representation. Don't use asctime, as it
3657 has undefined behavior for years outside the range -999..9999.
3659 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
3661 Fix race conditions involving setenv, gmtime, localtime, asctime.
3662 Without this fix, interrupts could mess up code that uses these
3663 nonreentrant functions, since setting TZ invalidates existing
3664 tm_zone or tzname values, and since most of these functions return
3665 pointers to static storage.
3666 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
3667 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
3668 Grow the critical sections to include not just invoking
3669 localtime/gmtime, but also accessing these functions' results
3670 including their tm_zone values if any, and any related TZ setting.
3671 (format_time_string): Last arg is now struct tm *, not struct tm **,
3672 so that the struct tm is saved in the critical section.
3673 All callers changed. Simplify allocation of initial buffer, partly
3674 motivated by the fact that memory allocation needs to be outside
3675 the critical section.
3677 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
3679 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
3680 with RESET_INTERVAL.
3682 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
3683 Remove duplicated buffer name initialization.
3685 2012-05-02 Jim Meyering <jim@meyering.net>
3687 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
3689 * xfns.c (x_window): Use xstrdup (Bug#11375).
3691 2012-05-02 Eli Zaretskii <eliz@gnu.org>
3693 * xdisp.c (pos_visible_p): If already at a newline from the
3694 display string before the 'while' loop, don't walk back the glyphs
3695 from it3.glyph_row. Solves assertion violation when the display
3696 string begins with a newline (egg.el). (Bug#11367)
3698 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
3700 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
3701 Move to simple.el.
3703 2012-05-01 Glenn Morris <rgm@gnu.org>
3705 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
3706 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
3707 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
3708 All were removed before 23.1.
3710 * dispnew.c: Remove HAVE_LIBNCURSES test;
3711 it is always true on relevant platforms.
3713 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
3714 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
3716 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
3718 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
3720 * .gdbinit (xpr): Remove checks for no longer existing misc types.
3721 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
3722 Remove.
3724 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
3726 Do not avoid creating empty evaporating overlays (Bug#9642).
3727 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
3728 That is, do not delete an evaporating overlay if it becomes
3729 empty after its bounds are adjusted to fit within its buffer.
3730 This fix caused other problems, and I'm reverting it until we get
3731 to the bottom of them.
3733 2012-04-27 Chong Yidong <cyd@gnu.org>
3735 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
3737 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3739 * xdisp.c (pos_visible_p): If the window start position is beyond
3740 ZV, start the display from buffer beginning. Prevents assertion
3741 violation in init_iterator when the minibuffer window is scrolled
3742 via the scroll bar.
3744 * window.c (window_scroll_pixel_based): Likewise.
3746 2012-04-27 Chong Yidong <cyd@gnu.org>
3748 * keymap.c (where_is_internal): Doc fix (Bug#10872).
3750 2012-04-27 Glenn Morris <rgm@gnu.org>
3752 * fileio.c (Fcopy_file, Fset_file_selinux_context):
3753 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
3755 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3757 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
3758 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
3760 2012-04-26 Eli Zaretskii <eliz@gnu.org>
3762 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
3763 display element, check also the underlying string or buffer
3764 character. (Bug#11341)
3766 * w32menu.c: Include w32heap.h.
3767 (add_menu_item): If the call to AppendMenuW (via
3768 unicode_append_menu) fails, disable Unicode menus only if we are
3769 running on Windows 9X/Me.
3771 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
3773 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
3774 (xgetint): Add missing shift for LSB tags.
3776 2012-04-24 Martin Rudalics <rudalics@gmx.at>
3778 * keyboard.c (read_char): Don't wipe echo area for select window
3779 events: These might get delayed via `mouse-autoselect-window'
3780 (Bug#11304).
3782 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
3784 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
3785 manipulation of :loaded-from data.
3787 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
3789 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
3790 now a cons (bug#11311).
3792 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
3794 Do not create empty overlays with the evaporate property (Bug#9642).
3795 * buffer.c (Fmove_overlay): Delete an evaporating overlay
3796 if it becomes empty after its bounds are adjusted to fit within
3797 its buffer. Without this fix, in a nonempty buffer (let ((o
3798 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
3799 yields an empty overlay that has the evaporate property, which is
3800 not supposed to happen.
3802 Fix minor GTK3 problems found by static checking.
3803 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
3804 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
3805 (struct _EmacsFixedClass, emacs_fixed_get_type):
3806 Move decls here from emacsgtkfixed.h, since they needn't be public.
3807 (emacs_fixed_get_type): Now static.
3808 (emacs_fixed_class_init): Omit unused local.
3809 (emacs_fixed_child_type): Remove; unused.
3810 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
3811 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
3812 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
3813 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
3814 (EMACS_FIXED_GET_CLASS): Remove; unused.
3815 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
3817 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
3818 Problem reported by Juanma Barranquero for Windows -Wunused-function.
3820 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
3822 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
3823 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
3824 (__malloc_size_t, __malloc_ptrdiff_t):
3825 Remove. All uses removed, replaced by the definiens if needed,
3826 since we can assume C89 or better now.
3827 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
3828 (protect_malloc_state, align, get_contiguous_space)
3829 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
3830 (malloc_atfork_handler_child, malloc_enable_thread)
3831 (malloc_initialize_1, __malloc_initialize, morecore_nolock)
3832 (_malloc_internal_nolock, _malloc_internal, malloc, _malloc)
3833 (_free, _realloc, _free_internal_nolock, _free_internal, free, cfree)
3834 (special_realloc, _realloc_internal_nolock, _realloc_internal)
3835 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
3836 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
3837 Define using prototypes, not old style.
3838 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
3839 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
3840 (align): Don't assume that signed integer overflow wraps around.
3841 Omit unused local var.
3842 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
3843 (_free_internal_nolock, memalign, mallochook, reallochook):
3844 Omit no-longer-needed casts.
3845 (valloc): Use getpagesize, not __getpagesize.
3846 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
3847 (struct hdr): The 'magic' member is now size_t, not unsigned long.
3849 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
3851 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
3853 Move functions from C to Lisp. Make non-blocking method calls
3854 the default. Implement further D-Bus standard interfaces.
3856 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
3857 (QCdbus_request_name_allow_replacement)
3858 (QCdbus_request_name_replace_existing)
3859 (QCdbus_request_name_do_not_queue)
3860 (QCdbus_request_name_reply_primary_owner)
3861 (QCdbus_request_name_reply_in_queue)
3862 (QCdbus_request_name_reply_exists)
3863 (QCdbus_request_name_reply_already_owner): Move to dbus.el.
3864 (QCdbus_registered_serial, QCdbus_registered_method)
3865 (QCdbus_registered_signal): New Lisp objects.
3866 (XD_DEBUG_MESSAGE): Use sizeof.
3867 (XD_MESSAGE_TYPE_TO_STRING, XD_OBJECT_TO_STRING)
3868 (XD_DBUS_VALIDATE_BUS_ADDRESS, XD_DBUS_VALIDATE_OBJECT)
3869 (XD_DBUS_VALIDATE_BUS_NAME, XD_DBUS_VALIDATE_PATH)

3902 * alloc.c: Handle unusual debugging option combinations.
3903 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
3904 since the two debugging options are incompatible.
3905 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
3906 is defined.
3907 (mem_init, mem_insert, mem_insert_fixup):
3908 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
3909 (NEED_MEM_INSERT): Remove; no longer needed.
3911 2012-04-22 Leo Liu <sdl.web@gmail.com>
3913 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
3915 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
3917 * sysdep.c [__FreeBSD__]: Minor cleanups.

3924 * sysdep.c (list_system_processes, system_process_attributes):
3925 Add implementation for FreeBSD (Bug#5243).
3927 2012-04-21 Andreas Schwab <schwab@linux-m68k.org>

3939 is nil.
3940 (print_object): Check for cycles even when print-circle is nil and
3941 print-gensym is t, but only check print_depth if print-circle is nil.
3943 2012-04-20 Chong Yidong <cyd@gnu.org>
3945 * process.c (wait_reading_process_output): If EIO occurs on a pty,
3946 set the status to "failed" and ensure that sentinel is run.
3948 2012-04-20 Glenn Morris <rgm@gnu.org>
3950 * process.c (Fset_process_inherit_coding_system_flag)
3951 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

3959 row, return zero immediately.
3960 (try_cursor_movement): If inside continuation line, don't back up
3961 farther than the first row after the header line, if any.
3962 Don't consider the header-line row as "partially visible", even if
3963 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
3965 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
3967 * lread.c (lisp_file_lexically_bound_p): Fix hang at ";-*-\n"
3968 (bug#11238).
3970 2012-04-20 Teodor Zlatanov <tzz@lifelogs.com>

3979 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
3980 -Wunused-result, -Wunused-variable. This should go away once
3981 the Emacs and Gnulib regex code is merged.
3982 (xmalloc, xrealloc): Now static.
3984 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

4000 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
4001 New extern decls, to avoid calling undeclared functions.
4002 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
4003 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
4004 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
4005 (NEED_MEM_INSERT): New macro.
4006 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
4007 Remove one incorrect comment and fix another.

4021 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
4022 Remove decls. This fixes an "It stinks!".
4024 * alloc.c (which_symbols): Fix alignment issue / type clash.
4026 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
4028 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

4039 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
4041 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
4042 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
4043 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
4044 * s/netbsd.h, s/sol2-6.h:
4045 Remove definition of GC_MARK_STACK, since the default now works.
4046 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
4047 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
4048 no longer the default.
4049 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
4051 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
4053 * lread.c (lisp_file_lexically_bound_p):
4054 Fix hang at ";-*-\n" (bug#11238).
4056 2012-04-14 Eli Zaretskii <eliz@gnu.org>
4058 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row

4063 * nsterm.m (constrainFrameRect): Always constrain when there is only
4064 one screen (Bug#10962).
4066 2012-04-13 Ken Brown <kbrown@cornell.edu>
4068 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.

4072 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
4074 2012-04-11 Daniel Colascione <dancol@dancol.org>
4076 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
4077 against is gone. It's better to use vfork now so that when Cygwin
4078 gains a new, working vfork, we use it automatically (bug#10398).
4080 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
4082 * window.c (save_window_save): Obey window-point-insertion-type.

4095 (force_quit_count): New var.
4096 (handle_interrupt): Use it.
4098 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
4100 * w32.c (w32_delayed_load): Record the full path of the library
4101 being loaded (bug#10424).
4103 2012-04-09 Glenn Morris <rgm@gnu.org>
4105 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
4106 not just in the obarray, before snarfing them. (Bug#11036)
4108 * Makefile.in ($(leimdir)/leim-list.el):
4109 Pass EMACS rather than BUILT_EMACS.
4111 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
4113 * process.c (make_process):

4118 Add convenience `GNUTLS_LOG2i' macro.
4120 * gnutls.c (gnutls_log_function2i): Convenience log function.
4121 (emacs_gnutls_read): Use new log functions,
4122 `gnutls_handshakes_tried' process member, and

4124 attempts per process (connection).
4126 2012-04-09 Chong Yidong <cyd@gnu.org>
4128 * eval.c (Fuser_variable_p, user_variable_p_eh)

4133 * minibuf.c (Fread_variable): Callers changed.
4135 2012-04-09 Eli Zaretskii <eliz@gnu.org>
4137 * xdisp.c (set_cursor_from_row): If the display string appears in
4138 the buffer at position that is closer to point than the position
4139 after the display string, display the cursor on the first glyph of
4140 the display string. Fixes cursor display when a 'display' text
4141 property immediately follows invisible text. (Bug#11094)
4143 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
4145 composite.c: use 'double' consistently
4146 * composite.c (get_composition_id): Use 'double' consistently
4147 instead of converting 'float' to 'double' and vice versa; this is
4148 easier to understand and avoids a GCC warning.
4150 2012-04-09 Glenn Morris <rgm@gnu.org>
4152 * Makefile.in: Generate leim-list with bootstrap-emacs, in
4153 preparation for dumping it with emacs. (Bug#4789)

4175 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
4176 (mark_memory): Mark Lisp_Objects only if pointers might hide in
4177 objects, as mark_maybe_pointer will catch them otherwise.
4178 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
4179 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

4195 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
4196 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
4197 [!WINDOWSNT]: New macros.
4198 (init_libxml2_functions, libxml2_loaded_p): New functions.
4199 (parse_region): Call fn_xmlCheckVersion instead of using the macro
4200 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
4201 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
4202 Calls xmlCleanupParser only if libxml2 was loaded (or statically
4203 linked in).
4204 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
4205 Call init_libxml2_functions before calling libxml2 functions.
4206 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
4208 * emacs.c: Don't include libxml/parser.h.
4209 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
4210 xmlCleanupParser directly.
4212 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
4214 2012-04-07 Eli Zaretskii <eliz@gnu.org>
4216 * indent.c (Fvertical_motion): If there is a display string at
4217 point, use it.vpos to compute how many lines to backtrack after
4218 move_it_to point. (Bug#11133)
4220 2012-04-06 Eli Zaretskii <eliz@gnu.org>
4222 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
4223 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
4224 about subtle differences between FETCH_CHAR* and STRING_CHAR*
4225 macros related to unification of CJK characters. For the details,
4226 see the discussion following the message here:
4227 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
4229 2012-04-04 Chong Yidong <cyd@gnu.org>
4231 * keyboard.c (Vdelayed_warnings_list): Doc fix.
4233 2012-04-01 Eli Zaretskii <eliz@gnu.org>
4235 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
4236 instead of alloca. (Bug#11138)
4238 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
4240 * w32menu.c (is_simple_dialog): Properly check lisp types.

4243 2012-03-31 Eli Zaretskii <eliz@gnu.org>
4245 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
4246 position we get to after a call to move_it_to fails the
4247 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
4248 only if we wind up in a string from display property. (Bug#11063)
4250 * window.c (Fdelete_other_windows_internal): Invalidate the row
4251 and column information about mouse highlight, so that redisplay
4252 restores it after reallocating the glyph matrices. (Bug#7464)
4254 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
4255 string comes from a `display' text property, use the buffer
4256 position of that property as if we actually saw that position in
4257 the row's glyphs.
4258 (move_it_by_lines): Remove the assertion that
4259 "it->current_x == 0 && it->hpos == 0" which can be legitimately
4260 violated when there's a before-string at the beginning of a line.
4261 (Bug#11063)
4263 2012-03-30 Eli Zaretskii <eliz@gnu.org>
4265 * xdisp.c (append_space_for_newline): If the default face was
4266 remapped, use the remapped face for the appended newline.
4267 (extend_face_to_end_of_line): Use the remapped default face for
4268 extending the face to the end of the line.
4269 (display_line): Call extend_face_to_end_of_line when the default
4270 face was remapped. (Bug#11068)
4272 2012-03-29 Eli Zaretskii <eliz@gnu.org>
4274 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
4276 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
4278 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
4280 2012-03-27 Glenn Morris <rgm@gnu.org>
4282 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
4283 Doc fixes.

4292 * keyboard.c (Vselection_inhibit_update_commands): New variable.
4293 (command_loop_1): Use it; inhibit selection update for
4294 handle-select-window too (Bug#8996).
4296 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
4298 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
4300 2012-03-25 Kenichi Handa <handa@m17n.org>
4302 * dispextern.h (struct glyph): Change the bit length of
4303 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
4305 2012-03-24 Eli Zaretskii <eliz@gnu.org>
4307 * s/ms-w32.h (tzname): Include time.h before redirecting to
4308 _tzname. Fixes the MSVC build. (Bug#9960)
4310 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
4312 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
4313 characters.
4315 * xterm.c (XTread_socket): Only modify handling_signal if
4316 !SYNC_INPUT. (Bug#11080)
4318 2012-03-23 Eli Zaretskii <eliz@gnu.org>
4320 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
4321 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
4322 when fetching a multibyte character consumes more bytes than
4323 CHAR_BYTES returns, due to unification of CJK characters in
4324 string_char. (Bug#11073)
4326 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
4328 * process.c (wait_reading_process_output): Handle pty disconnect
4329 by refraining from sending oneself a SIGCHLD (bug#10933).

4333 * dispextern.h (struct it): New member string_from_prefix_prop_p.
4335 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
4336 Mark string as coming from a prefix property.

4353 to reflect default non-nil value of redisplay-dont-pause.
4355 2012-03-19 Kenichi Handa <handa@m17n.org>

4358 it fit in a valid range (Bug#11003).
4360 2012-03-18 Eli Zaretskii <eliz@gnu.org>
4362 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
4363 that is not from display property, accept the row as a "cursor
4364 row" if one of the string's character has a non-nil `cursor'
4365 property. Fixes cursor positioning when there are newlines in
4366 overlay strings, e.g. in icomplete.el. (Bug#11035)
4368 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

4399 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
4400 zero (Bug#10954).
4402 2012-03-03 Glenn Morris <rgm@gnu.org>
4404 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.

4417 * buffer.c (buffer-list-update-hook): Doc fix.
4419 2012-02-29 Eli Zaretskii <eliz@gnu.org>

4422 push_it before setting up the iterator for the first overlay
4423 string, even if we have an empty string loaded.
4424 (next_overlay_string): If there's an empty string on the iterator
4425 stack, pop the stack. (Bug#10903)
4427 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
4429 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
4430 Suggested by Stefan Monnier in
4431 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
4432 * alloc.c (widen_to_Lisp_Object): New static function.
4433 (mark_memory): Also mark Lisp_Objects by fetching pointer words
4434 and widening them to Lisp_Objects. This would work even if
4435 USE_LSB_TAG is defined and wide integers are used, which might
4436 happen in a future version of Emacs.
4438 2012-02-25 Chong Yidong <cyd@gnu.org>
4440 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

4445 before saving to clipboard manager.
4447 2012-02-24 Chong Yidong <cyd@gnu.org>
4449 * keyboard.c (process_special_events): Handle all X selection

4459 (run_window_configuration_change_hook): Obey it.
4460 (syms_of_window): Initialize it.
4462 2012-02-22 Chong Yidong <cyd@gnu.org>
4464 * xterm.c (x_draw_image_relief): Add missing type check for

4469 * fileio.c (Vfile_name_handler_alist): Doc fix.
4471 * buffer.c (Fget_file_buffer): Protect against invalid file
4472 handler return value.

4477 when computing $valmask.
4479 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
4480 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
4481 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
4482 It's useless in that case, and it can cause problems on hosts
4483 that allocate halves of EMACS_INT values separately.
4484 Reported by Dan Horák. Diagnosed by Andreas Schwab in
4485 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
4486 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
4487 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
4488 it avoids undefined behavior on hosts where shifting right by more
4489 than the word width has undefined behavior.
4491 2012-02-19 Chong Yidong <cyd@gnu.org>
4493 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
4494 (Funhandled_file_name_directory, Ffile_name_as_directory)
4495 (Fdirectory_file_name, Fexpand_file_name)
4496 (Fsubstitute_in_file_name): Protect against invalid file handler
4497 return values (Bug#10845).

4511 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
4513 2012-02-15 Chong Yidong <cyd@gnu.org>
4515 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
4516 marked as special. Also, starting docstrings with * is obsolete.

4531 2012-02-12 Chong Yidong <cyd@gnu.org>
4533 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
4534 as that creates a dangerous corner case.
4536 * window.c (Fdelete_window_internal): Invalidate the mouse
4537 highlight (Bug#9904).
4539 2012-02-12 Glenn Morris <rgm@gnu.org>

4542 (Fx_get_selection_internal, Fx_disown_selection_internal)
4543 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
4544 * nsselect.m (Fx_own_selection_internal)
4545 (Fx_disown_selection_internal, Fx_selection_exists_p)
4546 (Fx_selection_owner_p, Fx_get_selection_internal):
4547 Sync docs and argument specs with the xselect.c versions.
4549 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
4551 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

4569 2012-02-07 Chong Yidong <cyd@gnu.org>
4571 * buffer.c (Fbuffer_local_variables)
4572 (buffer_lisp_local_variables): Handle unbound vars correctly;
4573 don't let Qunbound leak into Lisp.
4575 2012-02-07 Glenn Morris <rgm@gnu.org>
4577 * image.c (Fimagemagick_types): Doc fix.
4579 * image.c (imagemagick-render-type): Change it from a lisp object

4604 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
4605 after rounding frame sizes. (Bug#9723)
4607 2012-02-04 Eli Zaretskii <eliz@gnu.org>

4610 before BEGV. (Bug#10696)
4612 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
4614 Handle overflow when computing char display width (Bug#9496).
4615 * character.c (char_width): Return EMACS_INT, not int.
4616 (char_width, c_string_width): Check for overflow when
4617 computing the width; this is possible now that individual
4618 characters can have unbounded width. Problem introduced
4619 by merge from Emacs 23 on 2012-01-19.
4621 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

4643 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
4644 NULL (Bug#6988).

4650 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
4651 first 2 arguments are identical. This makes inserting large
4652 output from a subprocess an order of magnitude faster on
4653 MS-Windows, where all sbrk'ed memory is always contiguous.
4655 2012-01-31 Glenn Morris <rgm@gnu.org>
4657 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

4740 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
4741 from load-path also when installation-directory is nil. (Bug#10208)
4743 2012-01-10 Glenn Morris <rgm@gnu.org>

4752 * xdisp.c (rows_from_pos_range): Accept additional argument
4753 DISP_STRING, and accept any glyph in a row whose object is that
4754 string as eligible for mouse highlight. Fixes mouse highlight of
4755 display strings from overlays. (Bug#10464)
4757 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
4759 emacs: fix an auto-save permissions race condition (Bug#10400)
4760 * fileio.c (auto_saving_dir_umask): New static var.
4761 (Fmake_directory_internal): Use it.
4762 (do_auto_save_make_dir): Set it, instead of invoking chmod after
4763 creating the directory. The old code temporarily assigns
4764 too-generous permissions to the directory.
4765 (do_auto_save_eh): Clear it.
4766 (Fdo_auto_save): Catch all errors, not just file errors, so
4767 that the var is always cleared.

5154 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.

5271 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
5272 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
5273 is set, removing the need for VIRT_ADDRESS_VARIES.
5274 (PURE_P): Use a more-efficient implementation that needs just one
5275 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
5276 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
5277 to 4 (xorl, subq, cmpq, setbe).
5278 * alloc.c (pure): Always extern now, since that's the
5279 VIRT_ADDR_VARIES behavior.
5280 (PURE_POINTER_P): Use a single comparison, not two, for
5281 consistency with the new puresize.h.
5282 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

5289 (erase_phys_cursor, update_window_cursor, show_mouse_face)
5290 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
5291 behave as if the cursor position were at the window margin.
5293 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
5294 and the cursor position is out of bounds, behave as if the cursor

5368 * xdisp.c (display_line): Move the call to
5369 highlight_trailing_whitespace before the call to
5370 compute_line_metrics, since the latter needs to see the final

5759 New functions.
5760 (w32font_open_internal, compute_metrics):
5761 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
5762 instead of calling the "wide" APIs directly.
5764 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
5766 * w32.h (syms_of_w32font): Add prototype.
5768 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
5770 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
5771 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
5772 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
5773 (Fmove_to_window_line): Doc fix.
5775 2011-10-27 Chong Yidong <cyd@gnu.org>
5777 * process.c (make_process): Set gnutls_state to NULL.
5779 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
5780 non-NULL, regardless of GNUTLS_INITSTAGE.
5781 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
5782 an error. Set process slots as soon as we allocate them.
5784 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
5786 2011-10-27 Chong Yidong <cyd@gnu.org>
5788 * gnutls.c (emacs_gnutls_deinit): New function.
5789 Deallocate credentials structures as well as calling gnutls_deinit.
5790 (Fgnutls_deinit, Fgnutls_boot): Use it.
5792 * process.c (make_process): Initialize GnuTLS credentials to NULL.
5793 (deactivate_process): Call emacs_gnutls_deinit.
5795 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
5797 * image.c (x_create_x_image_and_pixmap):
5798 * w32.c (sys_rename, w32_delayed_load):
5799 * w32font.c (fill_in_logfont):
5800 * w32reg.c (x_get_string_resource): Silence compiler warnings.
5802 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
5804 * w32fns.c (w32_default_color_map): New function,
5805 extracted from Fw32_default_color_map.
5806 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
5808 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
5810 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
5812 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
5814 * keyboard.c (test_undefined): New function (bug#9751).
5815 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
5817 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
5819 * sysdep.c (init_sys_modes): Fix the check for the controlling
5820 terminal (Bug#6649).
5822 2011-10-20 Eli Zaretskii <eliz@gnu.org>
5824 * dispextern.h (struct bidi_it): New member next_en_type.
5826 * bidi.c (bidi_line_init): Initialize the next_en_type member.
5827 (bidi_resolve_explicit_1): When next_en_pos is valid for the
5828 current character, check also for next_en_type being WEAK_EN.
5829 (bidi_resolve_weak): Don't enter the expensive loop if the current
5830 position is before next_en_pos. Record the bidi type of the first
5831 non-ET, non-BN character we find, in addition to its position.
5832 (bidi_level_of_next_char): Invalidate next_en_type when
5833 next_en_pos is over-stepped.
5835 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
5837 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
5838 * editfns.c: Rewrite current-time-zone so that it invokes
5839 the equivalent of (format-time-string "%Z") to get the time zone name.
5840 This fixes a bug when the time zone name contains characters that
5841 need converting from the system time locale to Emacs internal format.
5842 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
5843 that patch fixed format-time-string to do the conversion, but
5844 I forgot to fix current-time-zone.
5845 (format_time_string): New function, containing most of
5846 what Fformat_time_string used to contain.
5847 (Fformat_time_string): Rewrite in terms of format_time_string.
5848 This doesn't change this function's behavior.
5849 (current-time-zone): Rewrite to use format_time_string.
5850 This fixes the bug reported by Michael Schierl in
5851 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
5852 Jason Rumney's 2007-06-07 change worked around this bug, but
5853 didn't fix it.
5854 * systime.h (tzname, timezone): Remove no-longer-used declarations.
5856 2011-10-19 Eli Zaretskii <eliz@gnu.org>
5858 * xdisp.c (start_display): If the character at POS is displayed
5859 via a display vector, reset IT->current.dpvec_index to zero.
5860 (try_window_reusing_current_matrix): If a line ends in a display
5861 vector or the next line starts in a display vector, continue
5862 redrawing the window even though the character position of
5863 start_row was reached.
5864 (Bug#9771, part 2)
5866 2011-10-18 Chong Yidong <cyd@gnu.org>
5868 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
5869 with nobreak-char-display too.
5871 2011-10-18 Eli Zaretskii <eliz@gnu.org>
5873 Fix part 3 of bug#9771.
5874 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
5875 (bidi_resolve_neutral): Don't enter the expensive loop looking for
5876 non-neutral characters if the current character is a paragraph
5877 separator (a.k.a. Newline). This avoids running the same
5878 expensive loop twice, once when we consume the preceding newline
5879 and the other time when the line actually needs to be displayed.
5880 Avoid the loop when we see neutrals on the base embedding level
5881 following a character whose directionality is the same as the
5882 paragraph's. This avoids running the expensive loop when a line
5883 ends in a long sequence of neutrals, like control characters.
5884 Add assertion against STRONG_AL type. Slightly rearrange code
5885 that determines the type of a neutral given the first non-neutral
5886 that follows it.
5887 (bidi_level_of_next_char): Set next_en_pos to zero when
5888 invalidating its info.
5890 2011-10-17 Eli Zaretskii <eliz@gnu.org>
5892 * xdisp.c (push_display_prop): Determine whether to record string
5893 or buffer position by IT->string, not by IT->method. Allow
5894 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
5895 (move_it_vertically_backward): Don't look for character position
5896 immediately after the newline when in a continuation line.
5897 (Bug#9771, part 1)
5899 2011-10-15 Martin Rudalics <rudalics@gmx.at>
5901 * window.c (coordinates_in_window): Rewrite and delabelize
5902 vertical border check. (Bug#5357) (Bug#9618)
5904 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
5906 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
5907 errors in XSetWindowBorder (bug#9310).
5909 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
5911 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
5912 avoid crash when xmalloc overrun checking is enabled.
5914 2011-10-13 Eli Zaretskii <eliz@gnu.org>
5916 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
5917 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
5918 cursor motion with <left> and <right> arrow keys.
5920 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
5921 some callers set that themselves.
5923 2011-10-12 Eli Zaretskii <eliz@gnu.org>
5925 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
5926 display string and the previous row comes from the same string and
5927 is empty. (Bug#9739) (Bug#9738)
5929 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
5931 * doc.c (get_doc_string): Encode file name (bug#9735).
5933 2011-10-12 Eli Zaretskii <eliz@gnu.org>
5935 * bidi.c (bidi_level_of_next_char):
5936 * xdisp.c (get_visually_first_element): Remove old incorrect
5937 comments regarding the Unicode Line Separator character.
5939 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
5941 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
5943 * alloc.c (Fgc_status): Do not access beyond zombies array
5944 boundary if nzombies > MAX_ZOMBIES.
5945 * alloc.c (dump_zombies): Add missing format specifier.
5947 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
5949 * xdisp.c (set_cursor_from_row): Simplify conditionals,
5950 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
5952 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
5953 Some packages use them to denote characters with modifiers.
5955 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
5957 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
5958 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
5959 matching a pp-number. Rename parameter var to var1.
5961 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
5963 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
5965 2011-10-08 Glenn Morris <rgm@gnu.org>
5967 * callint.c (Fcall_interactively): Give a more explicit error for the
5968 'c' case with a non-character input. (Bug#8479)
5970 2011-10-08 Eli Zaretskii <eliz@gnu.org>
5972 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
5973 lines.
5974 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
5975 lines that are hscrolled on the left.
5977 * dispnew.c (buffer_posn_from_coords): Account for a possible
5978 presence of header-line. (Bug#4426)
5980 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
5982 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
5983 Don't advertise functionality which we discourage or doesn't work.
5985 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
5987 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
5988 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
5989 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
5990 this makes Emacs dump core during garbage collection on rare
5991 occasions. sizeof is obviously inferior to offsetof here, so
5992 stick with offsetof.
5993 (GC_POINTER_ALIGNMENT): New macro.
5994 (mark_memory): Omit 3rd (offset) arg; caller changed.
5995 Don't assume EMACS_INT alignment is the same as pointer alignment.
5997 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
5999 * keyboard.c (read_key_sequence_remapped): New var.
6000 (read_key_sequence): Compute remapping in the right buffer.
6001 (command_loop_1): Use read_key_sequence's remapping directly.
6003 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6005 * dired.c (file_name_completion): Don't expand file name.
6006 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
6007 before checking file name handler.
6009 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
6010 they've been requested explicitly (bug#9591).
6012 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
6014 * keymap.c (Fsingle_key_description): Use make_specified_string
6015 instead of build_string to build string from push_key_description.
6016 (Bug#5193)
6018 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6020 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
6021 This fixes a Y2038 bug on 64-bit hosts.
6022 * buffer.c (reset_buffer):
6023 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
6024 (Fclear_buffer_auto_save_failure):
6025 Use 0, not -1, to represent an unset failure time, since time_t
6026 might not be signed.
6028 Remove dependency on glibc malloc internals.
6029 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6030 Move back here from lisp.h, but with their new implementations.
6031 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6032 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
6033 * charset.c (charset_table_init): New static var.
6034 (syms_of_charset): Use it instead of xmalloc. This removes a
6035 dependency on glibc malloc internals. See Eli Zaretskii's comment in
6036 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
6037 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6038 Move back to alloc.c.
6039 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6040 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
6042 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
6044 * nsterm.m (windowDidResize): Call x_set_window_size only when
6045 ns_in_resize is true. Otherwise set pixelwidth/height and
6046 call change_frame_size (Bug#9628).
6048 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6050 Port --enable-checking=all to Fedora 14 x86-64.
6051 * charset.c (syms_of_charset): Also account for glibc malloc's
6052 internal overhead when calculating the initial malloc maximum.
6054 Port --enable-checking=all to Fedora 14 x86.
6055 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6056 Move to lisp.h.
6057 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
6058 (overrun_check_realloc, overrun_check_free):
6059 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
6060 That way, xmalloc returns a properly-aligned pointer even if
6061 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
6062 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
6063 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
6064 into account when calculating the initial malloc maximum.
6065 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6066 Move here from alloc.c, so that charset.c can use it too.
6067 Properly align; the old code wasn't right for common 32-bit hosts
6068 when configured with --enable-checking=all.
6069 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6070 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
6072 2011-09-29 Eli Zaretskii <eliz@gnu.org>
6074 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
6075 use EDOM.
6077 2011-09-28 Eli Zaretskii <eliz@gnu.org>
6079 * xdisp.c (compute_display_string_end): If there's no display
6080 string at CHARPOS, return -1.
6082 * bidi.c (bidi_fetch_char): When compute_display_string_end
6083 returns a negative value, treat the character as a normal
6084 character not covered by a display string. (Bug#9624)
6086 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
6088 * lread.c (Fread_from_string): Fix typo in docstring.
6090 2011-09-27 Eli Zaretskii <eliz@gnu.org>
6092 * xdisp.c (handle_invisible_prop): If invisible text ends on a
6093 newline, reseat the iterator instead of bidi-iterating there one
6094 character at a time. (Bug#9610)
6095 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
6096 TO_CHARPOS if the bidi iterator is at base embedding level.
6098 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
6100 * lread.c (readevalloop): Use correct code for NBSP.
6101 (read1): Likewise. (Bug#9608)
6103 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
6105 * dbusbind.c (Fdbus_register_signal): When service is not
6106 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
6108 2011-09-25 Glenn Morris <rgm@gnu.org>
6110 * buffer.c (truncate-lines): Doc fix.
6112 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
6114 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
6115 (Fset_window_next_buffers): Doc fix.
6117 2011-09-24 Glenn Morris <rgm@gnu.org>
6119 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
6121 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
6123 Fix minor problems found by static checking.
6124 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
6125 * indent.c (Fvertical_motion): Fix == vs = typo.
6127 2011-09-24 Eli Zaretskii <eliz@gnu.org>
6129 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
6130 Default value is now t. Doc fix.
6132 * indent.c (Fvertical_motion): Compute and apply the overshoot
6133 logic when moving up, not only when moving down. Fix the
6134 confusing name and values of the it_overshoot_expected variable;
6135 logic changes accordingly. (Bug#9254) (Bug#9549)
6137 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
6138 CHARPOS is covered by a display string which includes newlines.
6139 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
6140 is covered by a display string with embedded newlines.
6142 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
6144 * dbusbind.c (Fdbus_register_signal): Add match rule to
6145 Vdbus_registered_objects_table. (Bug#9581)
6146 (Fdbus_register_method, Vdbus_registered_objects_table):
6147 Fix docstring.
6149 2011-09-24 Jim Meyering <meyering@redhat.com>
6151 do not ignore write error for any output size
6152 The previous change was incomplete.
6153 While it makes emacs --batch detect the vast majority of stdout
6154 write failures, errors were still ignored whenever the output size is
6155 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
6156 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
6157 && echo FAIL: ignored write error
6158 FAIL: ignored write error
6159 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
6160 && echo FAIL: ignored write error
6161 FAIL: ignored write error
6162 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
6164 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
6166 * emacs.c (Fkill_emacs): In noninteractive mode exit
6167 non-successfully if a write error occurred on stdout. (Bug#9574)
6169 2011-09-21 Eli Zaretskii <eliz@gnu.org>
6171 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
6172 the xassert test.
6174 * dispextern.h (struct it): Update the comment documenting what
6175 can it->OBJECT be.
6177 2011-09-20 Eli Zaretskii <eliz@gnu.org>
6179 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
6180 a display string, extend search for cursor position to end of row.
6181 (find_row_edges): If the row ends in a newline from a display
6182 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
6183 Handle the case of a display string with multiple newlines.
6184 (Fcurrent_bidi_paragraph_direction): Fix search for previous
6185 non-empty line. Fixes confusing cursor motion with arrow keys at
6186 the beginning of a line that starts with whitespace.
6188 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
6190 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
6191 (bug#9493).
6193 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
6195 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
6196 boolean (Bug#9154).
6198 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6200 * xdisp.c (display_line): Record maximum and minimum buffer
6201 positions even if no glyphs were produced (e.g., by a zero-width
6202 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
6203 buffer positions that will be removed from the glyph row because
6204 they don't fit.
6205 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
6206 column is beyond frame width: don't subtract 1 "pixel" when
6207 computing width of the stretch.
6208 (reseat_at_next_visible_line_start): Undo the change made on
6209 2011-09-17 that saved paragraph information and restored it after
6210 the call to `reseat'. (Bug#9545)
6212 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6214 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
6215 and turn window cursor on if cleared (Bug#9415).
6217 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
6219 * search.c (boyer_moore): Take unibyte characters from pattern
6220 literally. (Bug#9458)
6222 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6224 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
6226 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
6228 Fix minor problem found by static checking.
6229 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
6230 initialized, to pacify gcc -Wuninitialized.
6232 * fileio.c: Report proper errno when syscall falls.
6233 (Finsert_file_contents): Save and restore errno,
6234 so that report_file_error outputs the correct diagnostic.
6235 (Fwrite_region) [CLASH_DETECTION]: Likewise.
6237 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6239 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
6241 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6243 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
6244 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
6246 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6248 * xdisp.c (reseat_at_next_visible_line_start): Keep information
6249 about the current paragraph and restore it after the call to reseat.
6251 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
6252 (bidi_find_paragraph_start): Search back for paragraph beginning
6253 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
6254 (bidi_move_to_visually_next): Only trigger paragraph-related
6255 computations when the last character is a newline or at EOB, not
6256 just any NEUTRAL_B. (Bug#9470)
6258 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
6259 truncated lines if point is covered by a display string. (Bug#9524)
6261 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
6263 * xselect.c: Relax test for outgoing X longs (Bug#9498).
6264 (cons_to_x_long): New function.
6265 (lisp_data_to_selection_data): Use it. Correct the test for
6266 short-versus-long data; it was negated. Break out of vector
6267 loop, for efficiency, when a long datum is discovered.
6269 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
6271 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
6273 2011-09-16 Eli Zaretskii <eliz@gnu.org>
6275 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
6276 GCC PR/17406) by declaring this function with external scope.
6278 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6280 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
6281 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
6283 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
6285 * editfns.c (Fformat): Correctly handle text properties on "%%".
6287 2011-09-15 Eli Zaretskii <eliz@gnu.org>
6289 * xterm.c (x_draw_composite_glyph_string_foreground):
6290 * w32term.c (x_draw_composite_glyph_string_foreground):
6291 * term.c (encode_terminal_code):
6292 * composite.c (composition_update_it, get_composition_id):
6293 * xdisp.c (get_next_display_element)
6294 (fill_composite_glyph_string): Add comments about special meaning
6295 of TAB characters in a composition.
6297 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6299 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
6300 This occurs when processing a multibyte format.
6301 Problem reported by Wolfgang Jenker.
6303 2011-09-15 Johan Bockgård <bojohan@gnu.org>
6305 * xdisp.c (try_cursor_movement): Only check for exact match if
6306 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
6308 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6310 Remove unused external symbols.
6311 * dispextern.h (calc_pixel_width_or_height): Remove decl.
6312 * xdisp.c (calc_pixel_width_or_height): Now static.
6313 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
6314 * indent.c (check_display_width):
6315 * w32term.c: Fix comment to match code.
6316 * xterm.c, xterm.h (x_catching_errors): Remove.
6318 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6320 * xselect.c: Use signed conversions more consistently (Bug#9498).
6321 (selection_data_to_lisp_data): Assume incoming selection data are
6322 signed integers, not unsigned. This is to be consistent with
6323 outgoing selection data, which was modified to use signed integers
6324 in as part of the fix to Bug#9196 in response to Jan D.'s comment
6325 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
6326 expects long, not unsigned long.
6328 2011-09-14 Eli Zaretskii <eliz@gnu.org>
6330 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
6331 computation of loop end. Reported by Johan Bockgård
6332 <bojohan@gnu.org>.
6334 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
6336 * frame.c (Fother_visible_frames_p): Function deleted.
6338 2011-09-12 Eli Zaretskii <eliz@gnu.org>
6340 * indent.c (compute_motion): Process display vector front to back
6341 rather than the other way around. (Bug#2496)
6343 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6345 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
6347 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
6349 * minibuf.c (Fread_from_minibuffer): Doc fix.
6351 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6353 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
6354 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
6356 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
6358 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
6359 value for non-existent files.
6361 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6363 * fileio.c (Finsert_file_contents): If the file cannot be opened,
6364 set its "size" to -1. This will set the modtime_size field of
6365 the corresponding buffer to -1, which is what
6366 verify-visited-file-modtime expects for files that do not exist.
6367 (Bug#9139)
6369 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
6371 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
6372 here ...
6373 * lisp.h: ... from here. push_key_description is no longer
6374 defined in keyboard.c, so its declaration should not be in
6375 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
6376 logically belongs with push_key_description.
6378 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
6380 * buffer.h: Include <sys/types.h> instead of <time.h>.
6381 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
6382 Problem reported by Herbert J. Skuhra.
6384 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
6386 * xml.c (parse_region): Make the parsing work for
6387 non-comment-starting XML files again (bug#9144).
6389 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
6391 * image.c (gif_load): Fix calculation of bottom and right corner.
6392 (Bug#9468)
6394 2011-09-10 Eli Zaretskii <eliz@gnu.org>
6396 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
6397 redisplay in small windows.
6399 2011-09-09 Eli Zaretskii <eliz@gnu.org>
6401 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
6403 2011-09-08 Martin Rudalics <rudalics@gmx.at>
6405 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
6406 Operate on live windows only.
6408 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
6410 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
6412 2011-09-07 Eli Zaretskii <eliz@gnu.org>
6414 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
6415 only under bidi iteration.
6417 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
6419 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
6421 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6423 isnan: Fix porting problem to Solaris 10 with bundled gcc.
6424 Without this fix, the command to link temacs failed due to an
6425 undefined symbol __builtin_isnan. This is because
6426 /usr/include/iso/math_c99.h #defines isnan(x) to
6427 __builtin_isnan(x), but the bundled gcc, which identifies itself
6428 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
6429 a __builtin_isnan.
6430 * floatfns.c (isnan): #undef, and then #define to a clone of
6431 what's in data.c.
6432 (Fisnan): Always define, since it's always available now.
6433 (syms_of_floatfns): Always define isnan at the Lisp level.
6435 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6437 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
6439 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6441 * fileio.c: Fix bugs with large file offsets (Bug#9428).
6442 The previous code assumed that file offsets (off_t values) fit in
6443 EMACS_INT variables, which is not true on typical 32-bit hosts.
6444 The code messed up by falsely reporting buffer overflow in cases
6445 such as (insert-file-contents "big" nil 1 2) into an empty buffer
6446 when "big" contains more than 2**29 bytes, even though this
6447 inserts just one byte and does not overflow the buffer.
6448 (Finsert_file_contents): Store file offsets as off_t
6449 values, not as EMACS_INT values. Check for overflow when
6450 converting between EMACS_INT and off_t. When checking for
6451 buffer overflow or for overlap, take the offsets into account.
6452 Don't use EMACS_INT for small values where int suffices.
6453 When checking for overlap, fix a typo: ZV was used where
6454 ZV_BYTE was intended.
6455 (Fwrite_region): Don't assume off_t fits into 'long'.
6456 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
6458 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
6460 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
6462 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6464 sprintf-related integer and memory overflow issues (Bug#9412).
6466 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
6467 (esprintf, exprintf, evxprintf): New functions.
6468 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
6469 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
6470 (modify_event_symbol): Do not assume that the length of
6471 name_alist_or_stem is safe to alloca and fits in int.
6472 (Fexecute_extended_command): Likewise for function name and binding.
6473 (Frecursion_depth): Wrap around reliably on integer overflow.
6474 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
6475 since some callers pass EMACS_INT values.
6476 (Fsingle_key_description): Don't crash if symbol name contains more
6477 than MAX_ALLOCA bytes.
6478 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
6479 (get_minibuffer): Arg is now EMACS_INT, not int.
6480 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
6481 (esprintf, exprintf, evxprintf): New decls.
6482 * window.h (command_loop_level, minibuf_level): Reflect API changes.
6484 * dbusbind.c (signature_cat): New function.
6485 (xd_signature, Fdbus_register_signal):
6486 Do not overrun buffer; instead, report string overflow.
6488 * dispnew.c (add_window_display_history): Don't overrun buffer.
6489 Truncate instead; this is OK since it's just a log.
6491 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
6492 even if the time zone offset is outlandishly large.
6493 Don't mishandle offset == INT_MIN.
6495 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
6496 when creating daemon; the previous buffer-overflow check was incorrect.
6498 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
6499 which has the guts of the old verror function.
6501 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
6502 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
6504 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
6505 (font_unparse_xlfd): Don't blindly alloca long strings.
6506 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
6507 fits in int, when using sprintf. Use single snprintf to count
6508 length of string rather than counting it via multiple sprintfs;
6509 that's simpler and more reliable.
6510 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
6511 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
6512 sprintf, in case result does not fit in int.
6514 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
6515 (fontset_from_font): Print it.
6517 * frame.c (tty_frame_count): Now printmax_t, not int.
6518 (make_terminal_frame, set_term_frame_name): Print it.
6519 (x_report_frame_params): In X, window IDs are unsigned long,
6520 not signed long, so print them as unsigned.
6521 (validate_x_resource_name): Check for implausibly long names,
6522 and don't assume name length fits in 'int'.
6523 (x_get_resource_string): Don't blindly alloca invocation name;
6524 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
6525 not fit in int.
6527 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
6528 (xg_check_special_colors, xg_set_geometry):
6529 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
6531 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
6532 Use esprintf, not sprintf, in case result does not fit in int.
6534 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6535 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
6536 it as a large positive number.
6537 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
6538 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6540 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
6541 in case result does not fit in int.
6543 * print.c (float_to_string): Detect width overflow more reliably.
6544 (print_object): Make sprintf buffer a bit bigger, to avoid potential
6545 buffer overrun. Don't assume list length fits in 'int'. Treat
6546 print length of 0 as 0, not as infinity; to be consistent with other
6547 uses of print length in this function. Don't overflow print length
6548 index. Don't assume hash table size fits in 'long', or that
6549 vectorlike size fits in 'unsigned long'.
6551 * process.c (make_process): Use printmax_t, not int, to format
6552 process-name gensyms.
6554 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
6556 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
6557 to avoid potential buffer overrun.
6559 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
6560 if X resource line is longer than 512 bytes.
6562 * xfns.c (x_window): Make sprintf buffer a bit bigger
6563 to avoid potential buffer overrun.
6565 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
6567 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
6569 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6571 Integer overflow fixes for scrolling, etc.
6572 Without these, Emacs silently mishandles large integers sometimes.
6573 For example, "C-u 4294967297 M-x recenter" was treated as if
6574 it were "C-u 1 M-x recenter" on a typical 64-bit host.
6576 * xdisp.c (try_window_id): Check Emacs fixnum range before
6577 converting to 'int'.
6579 * window.c (window_scroll_line_based, Frecenter):
6580 Check that an Emacs fixnum is in range before assigning it to 'int'.
6581 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
6582 values converted from Emacs fixnums.
6583 (Frecenter): Don't wrap around a line count if it is out of 'int'
6584 range; instead, treat it as an extreme value.
6585 (Fset_window_configuration, compare_window_configurations):
6586 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
6588 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
6589 that can exceed INT_MAX. Check that EMACS_INT value is in range
6590 before assigning it to the (possibly-narrower) index.
6591 (match_limit): Don't assume that a fixnum can fit in 'int'.
6593 * print.c (print_object): Use ptrdiff_t, not int, for index that can
6594 exceed INT_MAX.
6596 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
6597 (Fvertical_motion): Don't wrap around LINES values that don't fit
6598 in 'int'. Instead, treat them as extreme values. This is good
6599 enough for windows, which can't have more than INT_MAX lines anyway.
6601 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
6603 * Require libxml/parser.h to avoid compilation warning.
6605 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
6607 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
6608 since this reportedly can destroy thread storage.
6610 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
6612 * syntax.c (find_defun_start): Update all cache variables if
6613 exiting early (Bug#9401).
6615 2011-08-30 Eli Zaretskii <eliz@gnu.org>
6617 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
6619 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
6620 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
6621 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
6623 * term.c (tty_append_glyph): New function.
6624 (produce_stretch_glyph): Static function and its prototype deleted.
6626 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
6627 Add prototypes.
6629 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
6631 * image.c (parse_image_spec): Check for nonnegative, not for positive,
6632 when checking :margin (Bug#9390).
6633 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
6634 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
6635 so that the name doesn't mislead. All uses changed.
6637 2011-08-28 Johan Bockgård <bojohan@gnu.org>
6639 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
6640 set_tty_hooks.
6642 2011-08-27 Eli Zaretskii <eliz@gnu.org>
6644 * xdisp.c (move_it_to): Don't bail out early when reaching
6645 position beyond to_charpos, if we are scanning backwards.
6646 (move_it_vertically_backward): When DY == 0, make sure we get to
6647 the first character in the line after the newline.
6649 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
6651 * ccl.c: Improve and simplify overflow checking (Bug#9196).
6652 (ccl_driver): Do not generate an out-of-range pointer.
6653 (Fccl_execute_on_string): Remove unnecessary check for
6654 integer overflow, noted by Stefan Monnier in
6655 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
6656 Remove a FIXME that didn't need fixing.
6657 Simplify the newly-introduced buffer reallocation code.
6659 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
6661 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
6663 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
6665 Integer and memory overflow issues (Bug#9196).
6667 * doc.c (get_doc_string): Rework so that
6668 get_doc_string_buffer_size is the actual buffer size, rather than
6669 being 1 less than the actual buffer size; this makes xpalloc more
6670 convenient.
6672 * image.c (x_allocate_bitmap_record, cache_image):
6673 * xselect.c (Fx_register_dnd_atom):
6674 Simplify previous changes by using xpalloc.
6676 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
6677 since either will do and ptrdiff_t is convenient with xpalloc.
6679 * charset.c (charset_table_size)
6680 (struct charset_sort_data.priority): Now ptrdiff_t.
6681 (charset_compare): Don't overflow if priorities differ greatly.
6682 (Fsort_charsets): Don't assume list length fits in int.
6683 Check for size-calculation overflow when allocating sort data.

6685 just under 64 KiB, to avoid problems with glibc malloc and mmap.
6687 * cmds.c (internal_self_insert): Check for size-calculation overflow.
6689 * composite.h (struct composition.glyph_len): Now int, not unsigned.
6690 The actual value is always <= INT_MAX, and leaving it unsigned made

6694 (struct face_cache.size): Now ptrdiff_t, for convenience in use
6695 with xpalloc. The values are still always <= INT_MAX.

6705 (revalidate_region_cache, know_region_cache, region_cache_forward)
6706 (region_cache_backward, pp_cache):
6707 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
6708 so that ptrdiff_t * can be passed to xpalloc.
6709 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
6710 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.

6727 Don't update size of array until after memory allocation succeeds,
6728 because xmalloc/xrealloc may not return.

6730 now that we have proper integer overflow checking.
6731 (record_overlay_string, overlay_strings): Catch overflows when
6732 calculating size of overlay_str_buf.
6734 * callproc.c (Fcall_process): Check for size overflow when
6735 calculating size of args2.
6736 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
6737 Normally we prefer signed values, but sticking with ptrdiff_t would
6738 require adding more-complicated checks.
6740 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
6741 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
6742 Redo buffer-overflow calculations to avoid integer overflow.

6781 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
6783 * emacs.c (main): Do not reallocate argv, since there is a null at
6784 the end that can be overwritten, and this way there's no need to
6785 worry about size-calculation overflow.
6786 (sort_args): Check for size-calculation overflow.
6788 * eval.c (init_eval_once, grow_specpdl): Don't update size until
6789 alloc succeeds.

6794 Check for integer overflow.
6795 (x_set_alpha): Do not assume XINT fits in int.
6797 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
6798 This is for the members text_lines, text_cols, total_lines, total_cols,
6799 where the system imposes an 'int' limit.
6801 * fringe.c (Fdefine_fringe_bitmap):
6802 Don't update size until alloc works.

6807 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
6808 Check for size-calculation overflow.
6809 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
6810 do, as we prefer signed integers.
6811 (id_to_widget.max_size, id_to_widget.used)
6812 (xg_store_widget_in_map, xg_remove_widget_from_map)
6813 (xg_get_widget_from_map, xg_get_scroll_id_for_window)

6815 Use and return ptrdiff_t, not int.
6816 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
6817 * gtkutil.h: Change prototypes to match the above.
6819 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

6866 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
6867 for command line length. Do not attempt to address one before the

6898 Check for size calculation overflow.
6899 (cache_face): Treat size calculation overflows as if they were

6915 (X_LONG_MIN): New macros.
6916 Use them to make the following changes clearer.
6917 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
6918 This change doesn't affect the value now, but it may help remind
6919 future maintainers not to raise the value too much later.
6920 (SELECTION_QUANTUM): Remove, replacing with ...
6921 (selection_quantum): ... new function, which avoids overflow.
6922 All uses changed.
6923 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

6932 Redo calculations to avoid overflow.
6933 (x_reply_selection_request): When sending hint, ceiling it at

6937 (lisp_data_to_selection_data, x_property_data_to_lisp):

6941 Don't store size until memory allocation succeeds.
6942 (x_get_window_property): Plug memory leak on memory exhaustion.
6943 Don't double-block input; malloc is safe here. Don't assume 2**34
6944 - 4 fits in unsigned long. Add an xassert to check
6945 XGetWindowProperty overflow. Be more careful about overflow
6946 calculations, and distinguish size from memory overflow better.

6948 unsigned int is less than INT_MAX.
6949 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

6952 in the range -65535 through -1 fit in an X unsigned short.
6953 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
6954 result parameters unless successful. Rely on cons_to_unsigned
6955 to report problems with elements; the old code wasn't right anyway.
6956 (x_check_property_data): Check for int overflow; we cannot use
6957 a wider type due to X limits.

6990 * lisp.h (hash_lookup, hash_put):
6991 * minibuf.c (Ftest_completion):
6992 Use ptrdiff_t for hash table indexes, not int (which is too
6993 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
6994 32-bit --with-wide-int hosts).
6996 * charset.c (Fdefine_charset_internal): Check for integer overflow.
6997 Add a FIXME comment about memory leaks.

7031 * keyboard.c: Overflow, signedness and related fixes.
7032 (make_lispy_movement): Use same integer type in forward decl
7033 that is used in the definition.
7034 (read_key_sequence, keyremap_step):
7035 Change bufsize argument back to int, undoing my 2011-03-30 change.

7037 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
7038 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
7039 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
7040 length, not size_t. Use ptrdiff_t for index, not int.
7041 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
7042 possibility of integer overflow.

7069 (png_load, gif_load, svg_load_image):
7070 Prefer int to unsigned where either will do.
7071 (tiff_handler): New function, combining the cores of the
7072 old tiff_error_handler and tiff_warning_handler.
7073 This function is rewritten to use vsnprintf and thereby avoid
7074 stack buffer overflows. It uses only the features of vsnprintf
7075 that are common to both POSIX and native Microsoft.
7076 (tiff_error_handler, tiff_warning_handler): Use it.
7077 (tiff_load, gif_load, imagemagick_load_image):

7081 the integer types that MagickCropImage accepts. Don't assume
7082 Vimagemagick_render_type has a nonnegative value. Don't assume
7083 size_t fits in 'long'.
7084 (gs_load): Use printmax_t to print the widest integers possible.

7089 * xdisp.c (redisplay_window): Don't force window start if point
7090 will be invisible in the resulting window. (Bug#9324)
7092 2011-08-25 Eli Zaretskii <eliz@gnu.org>
7094 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when

7097 handle_single_display_spec, not just 1 or zero.
7098 (handle_single_display_spec): If the display spec is of the form
7099 `(space ...)', and specifies display in the text area, return 2
7100 rather than 1.
7101 (try_cursor_movement): Check for the need to scroll more
7102 accurately, and prefer exact match for point under bidi.
7103 Don't advance `row' beyond the last row of the window.
7105 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
7106 into disp_prop; all users changed.
7108 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

7120 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
7121 buffers, return left-to-right.
7122 (set_cursor_from_row): Consider candidate row a win if its glyph
7123 represents a newline and point is on that newline. Fixes cursor
7124 positioning on the newline at EOL of R2L text within L2R
7125 paragraph, and vice versa.
7126 (try_cursor_movement): Check continued rows, in addition to
7127 continuation rows. Fixes unwarranted scroll when point enters a
7128 continued line of R2L text within an L2R paragraph, or vice versa.
7129 (cursor_row_p): Consider the case of point being equal to
7130 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
7131 from the end of a short line to the beginning of a continued line
7132 of R2L text within L2R paragraph.
7133 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
7134 composed characters.
7136 * bidi.c (bidi_check_type): Use xassert.
7137 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
7138 members.
7140 2011-08-23 Eli Zaretskii <eliz@gnu.org>
7142 * bidi.c (bidi_get_type): Abort if we get zero as the bidi type of
7143 a character.
7145 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
7147 * nsfont.m (ns_otf_to_script): Fix typo.
7149 2011-08-22 Kenichi Handa <handa@m17n.org>
7151 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
7152 extra slot even if the purpose is char-code-property-table.
7154 2011-08-23 Eli Zaretskii <eliz@gnu.org>
7156 * xdisp.c (redisplay_window): When computing centering_position,
7157 account for the height of the header line. (Bug#8874)
7159 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
7160 instead of CHAR_TO_BYTE. Fixes a crash when a completion
7161 candidate is selected by the mouse, and that candidate has a
7162 composed character under the mouse.
7164 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
7165 coordinates reported by pos-visible-in-window-p for a composed
7166 character in column zero.
7168 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
7170 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
7172 2011-08-22 Eli Zaretskii <eliz@gnu.org>
7174 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
7175 consider it a hit if to_charpos is anywhere in the range of the
7176 composed buffer positions.
7178 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
7180 * image.c (gif_load): Don't assume that each subimage has the same
7181 dimensions as the base image. Handle disposal method that is
7182 "undefined" by the gif spec (Bug#9335).
7184 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
7186 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
7187 (Fcondition_case): Document `debug' symbol in error handler.
7189 2011-08-19 Eli Zaretskii <eliz@gnu.org>
7191 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
7192 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
7193 from an Org mode buffer to a Speedbar frame.
7195 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
7196 a composition, take its buffer position from IT->cmp_it.charpos.
7197 Fixes cursor positioning at the beginning of a line that begins
7198 with a composed character.
7200 2011-08-18 Eli Zaretskii <eliz@gnu.org>
7202 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
7203 character bidirectional type, use STRONG_L instead. Fixes crashes
7204 in a buffer produced by `describe-categories'.
7206 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
7207 members before the level stack, so they would be saved and
7208 restored when copying iterator state. Fixes incorrect reordering
7209 around TABs covered by display properties.
7211 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
7213 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
7215 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
7217 * eval.c (internal_condition_case, internal_condition_case_1)
7218 (internal_condition_case_2, internal_condition_case_n):
7219 Remove unnecessary aborts (Bug#9081).
7221 2011-08-17 Eli Zaretskii <eliz@gnu.org>
7223 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
7224 has no `load' handler, try opening the file locally. (Bug#9311)
7226 2011-08-16 Ken Brown <kbrown@cornell.edu>
7228 * gmalloc.c: Expand comment.
7230 2011-08-16 Eli Zaretskii <eliz@gnu.org>
7232 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
7233 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
7235 2011-08-16 Ken Brown <kbrown@cornell.edu>
7237 Fix memory allocation problems in Cygwin build (Bug#9273).
7239 * unexcw.c ( __malloc_initialized): Declare external variable.

7242 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
7243 New variables.
7244 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
7245 dumped emacs.
7246 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
7247 in the static heap.
7248 [CYGWIN] (special_realloc): New function.
7249 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
7250 requests to realloc storage in the static heap.

7261 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
7263 * dispextern.h: Fix a typo in the comment to bidi_type_t.
7265 * chartab.c: Improve commentary for the uniprop_table API.
7267 * bidi.c (bidi_paragraph_init): Support zero value of
7268 bidi_ignore_explicit_marks_for_paragraph_level.

7272 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
7273 coordinates of the iterator when restoring from ppos_it.
7274 (Bug#9296)
7276 2011-08-14 Kenichi Handa <handa@m17n.org>
7278 * process.c (create_process): Call setup_process_coding_systems
7279 after the pid of the process is set to -1 (Bug#8162).
7281 2011-08-14 Eli Zaretskii <eliz@gnu.org>
7283 * xdisp.c (move_it_in_display_line_to): Don't invoke
7284 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
7285 ppos_it. Fixes vertical cursor motion when line beginning is
7286 covered by an image. (Bug#9296)
7288 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
7290 * nsterm.h (ns_run_ascript): Declare.

7293 * nsfns.m (as_script, as_result, as_status): New static variables.
7294 (ns_run_ascript): New function.
7295 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
7296 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
7297 the event loop. Get status from as_status (Bug#7276).
7299 * nsterm.m (sendEvent): If event is NSApplicationDefined and
7300 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
7301 the event loop (Bug#7276).
7303 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
7305 * gnutls.c (QCgnutls_bootprop_priority)
7306 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
7307 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
7308 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
7309 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
7310 (QCgnutls_bootprop_verify_hostname_error)
7311 (QCgnutls_bootprop_callbacks_verify): Rename from
7312 Qgnutls_bootprop_..., all uses changed.
7314 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
7315 uses changed.
7317 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>

7324 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
7326 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
7327 (Fnetwork_interface_list): Allocate in increments of bytes instead
7328 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
7329 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
7330 sockaddr.
7331 (struct ifflag_def): notrailers is smart on OSX.
7332 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
7333 Get hardware address with getifaddrs if available.
7335 2011-08-12 Eli Zaretskii <eliz@gnu.org>
7337 * xdisp.c (iterate_out_of_display_property): xassert that
7338 IT->position is set to within IT->object's boundaries. Break from
7339 the loop as soon as EOB is reached; avoids infloops in redisplay
7340 when IT->position is set up wrongly due to some bug.
7341 Set IT->current to match the bidi iterator unconditionally.
7342 (push_display_prop): Allow GET_FROM_STRING as IT->method on
7343 entry. Force push_it to save on the stack the current
7344 buffer/string position, to be restored by pop_it. Fix flags in
7345 the iterator structure wrt the object coming from a display
7346 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
7347 properties. (Bug#9284)
7349 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
7351 * fontset.c (fontset_get_font_group): Add proper type checks.

7364 no-display-properties-and-no-overlays under bidi display.
7365 Set disp_pos in the bidi iterator to avoid searches for display
7366 properties and overlays.
7368 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
7370 * editfns.c (Fset_time_zone_rule): Document relationship with the
7371 setenv function.

7374 the font entity extracted from the cache (Bug#8109).
7376 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
7378 * composite.c (autocmp_chars): Don't reset point. That is done by
7379 restore_point_unwind (Bug#5984).
7381 2011-08-07 Juri Linkov <juri@jurta.org>
7383 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
7384 to show the arg `TIME' instead of `TIMEVAL'.
7386 2011-08-06 Eli Zaretskii <eliz@gnu.org>
7388 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
7389 display property strides EOL and includes a newline, as in
7390 longlines-mode. (Bug#9254)
7391 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
7392 word-wrap under bidirectional display. (Bug#9224)
7394 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
7395 is non-zero, even if the data buffer is NULL. Fixes a crash in
7396 vertical-motion with longlines-mode. (Bug#9254)
7398 2011-08-05 Eli Zaretskii <eliz@gnu.org>
7400 * bidi.c <bidi_cache_total_alloc>: Now static.
7401 (bidi_initialize): Initialize bidi_cache_total_alloc.
7403 * xdisp.c (display_line): Release buffer allocated for shelved bidi
7404 cache. (Bug#9221)
7406 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
7407 amount allocated this far in `bidi_cache_total_alloc'.
7408 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
7409 non-zero, only free the data buffer without restoring the cache
7410 contents. All callers changed.
7412 * dispextern.h (bidi_unshelve_cache): Update prototype.
7414 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
7415 (move_it_in_display_line, move_it_to)
7416 (move_it_vertically_backward, move_it_by_lines): Replace the call
7417 to xfree to an equivalent call to bidi_unshelve_cache.
7418 (move_it_in_display_line_to): Fix logic of returning
7419 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
7421 2011-08-05 Eli Zaretskii <eliz@gnu.org>
7423 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
7424 came from a string character with a `cursor' property. (Bug#9229)
7426 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
7428 * Makefile.in (LIB_PTHREAD): New variable.
7429 (LIBES): Add LIB_PTHREAD (Bug#9216).
7431 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
7432 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).

7438 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
7440 * xterm.c (x_find_topmost_parent): New function.
7441 (x_set_frame_alpha): Find topmost parent window with
7442 x_find_topmost_parent and set the property there also (bug#9181).
7443 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
7445 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>

7459 * xdisp.c (compute_display_string_pos): Remove unused local.
7461 2011-08-02 Eli Zaretskii <eliz@gnu.org>
7463 Fix slow cursor motion and scrolling in large buffers with
7464 selective display, like Org Mode buffers. (Bug#9218)

7468 * xdisp.c: Remove one-slot cache of display string positions.
7469 (compute_display_string_pos): Accept an additional argument

7471 for a display string or property. If found, set DISP_PROP_P
7472 non-zero.
7474 * bidi.c (bidi_fetch_char): Accept an additional argument
7475 DISP_PROP_P, and pass it to compute_display_string_pos.
7476 Only handle text covered by a display string if DISP_PROP_P is returned
7477 non-zero. All callers of bidi_fetch_char changed.
7479 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
7481 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.

7486 last character M-[char] is translated to ESC [char] (bug#7541).
7488 2011-08-02 Kenichi Handa <handa@m17n.org>
7490 * lisp.h (uniprop_table): Extern it.
7492 * chartab.c (uniprop_table): Make it non-static.
7494 2011-08-01 Eli Zaretskii <eliz@gnu.org>
7496 * xdisp.c (forward_to_next_line_start): Accept additional argument
7497 BIDI_IT_PREV, and store into it the state of the bidi iterator had
7498 on the newline.
7499 (reseat_at_next_visible_line_start): Use the bidi iterator state
7500 returned by forward_to_next_line_start to restore the state of
7501 it->bidi_it after backing up to previous newline. (Bug#9212)
7503 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
7505 * regex.c (re_comp): Protoize.
7506 (re_exec): Fix return type.
7507 (regexec): Fix type of `ret'. (Bug#9203)
7509 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7511 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
7512 This is needed if max-image-size is a floating-point number.
7514 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
7516 * print.c (print_object): Print empty symbol as ##.

7523 setting frame foreground color (Bug#9175).
7524 (x_set_background_color): Likewise.
7526 * nsmenu.m (-setText): Size tooltip dimensions precisely to
7527 contents (Bug#9176).
7528 (EmacsTooltip -init): Remove bezels and add shadows to
7529 tooltip windows.

7540 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
7542 Implement strike-through and overline on NextStep (Bug#8863).
7544 * nsfont.m (nsfont_open): Use underline position provided by font,
7545 instead of hard-coded value of 2.
7546 (nsfont_draw): Call ns_draw_text_decoration instead.

7559 default.
7561 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7563 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
7564 Without this fix, if a signal arrives just after memory fills up,
7565 'malloc' might be invoked reentrantly.
7567 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
7568 In other words, assume that every image size is allowed, on non-X
7569 hosts. This assumption is probably wrong, but it lets Emacs compile.
7571 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
7573 * regex.c (re_iswctype): Convert return values to boolean.
7575 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>

7578 string position if the buffer had its restriction changed.
7579 (Bug#9184)
7581 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7583 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
7585 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7587 Integer signedness and overflow and related fixes. (Bug#9079)
7589 * bidi.c: Integer size and overflow fixes.
7590 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
7591 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
7592 (bidi_cache_find_level_change, bidi_cache_ensure_space)
7593 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
7594 (bidi_find_other_level_edge):
7595 Use ptrdiff_t instead of EMACS_INT where either will do.
7596 This works better on 32-bit hosts configured --with-wide-int.
7597 (bidi_cache_ensure_space): Check for size-calculation overflow.
7598 Use % rather than repeated addition, for better worst-case speed.
7599 Don't set bidi_cache_size until after xrealloc returns, because it
7600 might not return.
7601 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
7602 (bidi_cache_ensure_space): Also check that the bidi cache size
7603 does not exceed that of the largest Lisp string or buffer. See Eli
7604 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
7606 * alloc.c (__malloc_size_t): Remove.
7607 All uses replaced by size_t. See Andreas Schwab's note
7608 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
7610 * image.c: Improve checking for integer overflow.
7611 (check_image_size): Assume that f is nonnull, since
7612 it is always nonnull in practice. This is one less thing to
7613 worry about when checking for integer overflow later.
7614 (x_check_image_size): New function, which checks for integer
7615 overflow issues inside X.
7616 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
7617 This removes the need for a memory_full check.
7618 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
7619 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
7620 (xbm_read_bitmap_data): Change locals back to 'int', since
7621 their values must fit in 'int'.
7622 (xpm_load_image, png_load, tiff_load):
7623 Invoke x_create_x_image_and_pixmap earlier,
7624 to avoid much needless work if the image is too large.
7625 (tiff_load): Treat overly large images as if
7626 x_create_x_image_and_pixmap failed, not as malloc failures.
7627 (gs_load): Use x_check_image_size.
7629 * gtkutil.c: Omit integer casts.
7630 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
7631 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
7633 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
7635 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
7636 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
7637 would wrongly return t on a 64-bit host.
7639 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
7640 The plain *_OVERFLOW macros run afoul of GCC bug 49705
7641 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
7642 and therefore cause GCC to emit a bogus diagnostic in some cases.
7644 * image.c: Integer signedness and overflow and related fixes.
7645 This is not an exhaustive set of fixes, but it's time to
7646 record what I've got.
7647 (lookup_pixel_color, check_image_size): Remove redundant decls.
7648 (check_image_size): Don't assume that arbitrary EMACS_INT values
7649 fit in 'int', or that arbitrary 'double' values fit in 'int'.
7650 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
7651 (tiff_load, imagemagick_load_image):
7652 Check for overflow in size calculations.
7653 (x_create_x_image_and_pixmap): Remove unnecessary test for
7654 xmalloc returning NULL; that can't happen.
7655 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
7656 (xpm_color_bucket): Use better integer hashing function.
7657 (xpm_cache_color): Don't possibly over-allocate memory.
7658 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
7659 (gif_memory_source):
7660 Use ptrdiff_t, not int or size_t, to record sizes.
7661 (png_load): Don't assume values greater than 2**31 fit in 'int'.
7662 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
7663 either works, as we prefer signed integers.
7664 (tiff_read_from_memory, tiff_write_from_memory):
7665 Return tsize_t, not size_t, since that's what the TIFF API wants.
7666 (tiff_read_from_memory): Don't fail simply because the read would
7667 go past EOF; instead, return a short read.
7668 (tiff_load): Omit no-longer-needed casts.
7669 (Fimagemagick_types): Don't assume size fits into 'int'.
7671 Improve hashing quality when configured --with-wide-int.
7672 * fns.c (hash_string): New function, taken from sxhash_string.
7673 Do not discard information about ASCII character case; this
7674 discarding is no longer needed.
7675 (sxhash-string): Use it. Change sig to match it. Caller changed.
7676 * lisp.h: Declare it.
7677 * lread.c (hash_string): Remove, since we now use fns.c's version.
7678 The fns.c version returns a wider integer if --with-wide-int is
7679 specified, so this should help the quality of the hashing a bit.
7681 * emacs.c: Integer overflow minor fix.
7682 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
7683 Define only if GNU_LINUX.
7684 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
7686 * dispnew.c: Integer signedness and overflow fixes.
7687 Remove unnecessary forward decls, that were a maintenance hassle.
7688 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
7689 All uses changed.
7690 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
7691 (scrolling_window): Use ptrdiff_t, not int, for byte count.
7692 (prepare_desired_row, line_draw_cost):
7693 Use int, not unsigned, where either works.
7694 (save_current_matrix, restore_current_matrix):
7695 Use ptrdiff_t, not size_t, where either works.
7696 (init_display): Check for overflow more accurately, and without
7697 relying on undefined behavior.
7699 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
7700 Remove, replacing with the new symbols in lisp.h. All uses changed.
7701 * fileio.c (make_temp_name):
7702 * filelock.c (lock_file_1, lock_file):
7703 * xdisp.c (message_dolog):
7704 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
7705 Use pMd etc. instead.
7706 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
7707 replacing the pWIDE etc. symbols removed from editfns.c.
7709 * keyboard.h (num_input_events): Now uintmax_t.
7710 This is (very slightly) less likely to mess up due to wraparound.
7711 All uses changed.
7713 * buffer.c: Integer signedness fixes.
7714 (alloc_buffer_text, enlarge_buffer_text):
7715 Use ptrdiff_t rather than size_t when either will do, as we prefer
7716 signed integers.
7718 * alloc.c: Integer signedness and overflow fixes.
7719 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
7720 (__malloc_size_t): Default to size_t, not to int.
7721 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
7722 (Fgarbage_collect, mark_object_loop_halt, mark_object):
7723 Prefer ptrdiff_t to size_t when either would do, as we prefer
7724 signed integers.
7725 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
7726 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
7727 Now const. Initialize with values that are in range even if char
7728 is signed.
7729 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
7730 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
7731 These functions do the right thing with sizes > 2**32.
7732 (check_depth): Now ptrdiff_t, not int.
7733 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
7734 Adjust to new way of storing sizes. Check for size overflow bugs
7735 in rest of code.
7736 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
7737 slightly wrong anyway, as it missed one instance of
7738 XMALLOC_OVERRUN_CHECK_OVERHEAD.
7739 (refill_memory_reserve): Omit needless cast to size_t.
7740 (mark_object_loop_halt): Mark as externally visible.
7742 * xselect.c: Integer signedness and overflow fixes.
7743 (Fx_register_dnd_atom, x_handle_dnd_message):
7744 Use ptrdiff_t, not size_t, since we prefer signed.
7745 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
7746 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
7747 x_dnd_atoms_size and x_dnd_atoms_length.
7749 * doprnt.c: Prefer signed to unsigned when either works.
7750 * eval.c (verror):
7751 * doprnt.c (doprnt):
7752 * lisp.h (doprnt):
7753 * xdisp.c (vmessage):
7754 Use ptrdiff_t, not size_t, when using or implementing doprnt,
7755 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
7756 prefer signed arithmetic to avoid comparison confusion.
7757 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
7758 but is a bit tricky.
7760 Assume freestanding C89 headers, string.h, stdlib.h.
7761 * data.c, doprnt.c, floatfns.c, print.c:
7762 Include float.h unconditionally.
7763 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
7764 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
7765 * regex.c: Likewise for stddef.h, string.h.
7766 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
7767 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
7768 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
7769 (STDC_HEADERS): Remove obsolete defines.
7770 * sysdep.c: Include limits.h unconditionally.
7772 Assume support for memcmp, memcpy, memmove, memset.
7773 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
7774 * regex.c (memcmp, memcpy):
7775 Remove; we assume C89 now.
7777 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
7778 (__malloc_safe_bcopy): Remove; no longer needed.
7780 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
7781 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
7782 well either way, and we prefer signed to unsigned.
7784 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
7786 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
7787 closes the connection while we're reading (bug#9182).
7789 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
7791 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
7792 are specified (Bug#9168).
7794 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
7796 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
7797 Found by GCC static checking and --with-wide-int on a 32-bit host.
7799 2011-07-25 Eli Zaretskii <eliz@gnu.org>
7801 * xdisp.c (compute_display_string_pos): Fix logic of caching
7802 previous display string position. Initialize cached_prev_pos to
7803 -1. Fixes slow-down at the beginning of a buffer.
7805 2011-07-24 Eli Zaretskii <eliz@gnu.org>
7807 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
7808 for attrs[LFACE_FONTSET_INDEX].
7810 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
7812 * xml.c (parse_region): Remove unused local
7813 that was recently introduced.
7815 2011-07-23 Eli Zaretskii <eliz@gnu.org>
7817 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
7818 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
7820 * xdisp.c (move_it_in_display_line_to): Record the best matching
7821 position for TO_CHARPOS while scanning the line, and restore it on
7822 exit if none of the characters scanned was an exact match.
7823 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
7824 when exact match is impossible due to invisible text, and the
7825 lines are truncated.
7827 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
7829 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
7830 for OSX >= 10.7.
7832 2011-07-22 Eli Zaretskii <eliz@gnu.org>
7834 Fix a significant slow-down of cursor motion with C-n, C-p,
7835 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
7836 auto-repeat under bidi redisplay in fontified buffers.
7837 * xdisp.c (compute_stop_pos_backwards): New function.
7838 (next_element_from_buffer): Call compute_stop_pos_backwards to
7839 find a suitable prev_stop when we find ourselves before
7840 base_level_stop.
7841 (reseat): Don't look for prev_stop, as that could mean a very long
7842 run.
7843 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
7844 <cached_disp_overlay_modiff>: Cache for last found display string
7845 position.
7846 (compute_display_string_pos): Return the cached position if asked
7847 about the same buffer in the same area of character positions, and
7848 the buffer wasn't changed since the time the display string
7849 position was cached.
7851 2011-07-22 Eli Zaretskii <eliz@gnu.org>
7853 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
7854 is an integer, which is important for empty lines. (Bug#9149)
7856 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
7858 * frame.c (Fmodify_frame_parameters): In tty case, update the
7859 default face if necessary (Bug#4238).
7861 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
7863 * editfns.c (Fstring_to_char): No need to explain what a character
7864 is in the docstring (Bug#6576).
7866 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
7868 * xml.c (parse_region): Make sure we always return a tree.
7870 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
7872 * xml.c (parse_region): If a document contains only comments,
7873 return that, too.
7875 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
7877 * xml.c (make_dom): Return comments, too.
7879 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
7881 Port to OpenBSD.
7882 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
7883 and the surrounding thread.
7884 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
7885 rather than fgets, and retry after EINTR. Otherwise, 'emacs
7886 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
7887 timer goes off.
7888 * s/openbsd.h (BROKEN_SIGIO): Define.
7889 * unexelf.c (unexec) [__OpenBSD__]:
7890 Don't update the .mdebug section of the Alpha COFF symbol table.
7892 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7894 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
7895 (bug#8460).
7897 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
7899 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
7900 This fixes some race conditions on the permissions of any newly
7901 created file.
7903 * alloc.c (valid_pointer_p): Use pipe, not open.
7904 This fixes some permissions issues when debugging.
7906 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
7907 If fchown fails to set both uid and gid, try to set just gid,
7908 as that is sometimes allowed. Adjust the file's mode to eliminate
7909 setuid or setgid bits that are inappropriate if fchown fails.
7911 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
7913 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
7914 to compare Lisp_Objects.
7915 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
7916 global_gnutls_log_level, don't mistake it for a Lisp_Object.
7917 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
7919 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
7921 * lread.c (read_integer): Unread even EOF character.
7922 (read1): Likewise. Properly record start position of symbol.
7924 * lread.c (read1): Read `#:' as empty uninterned symbol if no
7925 symbol character follows.
7927 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
7929 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
7930 This works around a problem with the previous change to Fcopy_file.
7931 Recent glibc declares fchown with __attribute__((warn_unused_result)),
7932 and without this change, GCC might complain about discarding
7933 fchown's return value.
7935 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
7937 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
7939 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
7941 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
7943 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
7945 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
7946 it's used from the C level.
7948 * process.c: Use the same condition for POLL_FOR_INPUT in both
7949 keyboard.c and process.c (bug#1858).
7951 2011-07-09 Lawrence Mitchell <wence@gmx.li>
7953 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
7954 (Fgnutls_boot): Use it.
7956 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
7958 * doc.c (Fsubstitute_command_keys): Revert last change.
7960 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
7962 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
7963 quotes the next character, and doesn't affect other longer
7964 sequences (bug#8935).
7966 * lread.c (syms_of_lread): Clarify that is isn't only
7967 `eval-buffer' and `eval-defun' that's affected by
7968 `lexical-binding' (bug#8460).
7970 2011-07-15 Eli Zaretskii <eliz@gnu.org>
7972 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
7973 bidi redisplay when a line includes both an image and is truncated.
7975 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
7977 Fix minor problems found by static checking.
7978 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
7979 (elsz): Now a signed constant, not a size_t var. We prefer signed
7980 types to unsigned, to avoid integer comparison confusion. Without
7981 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
7982 "cannot optimize loop, the loop counter may overflow", a symptom
7983 of the confusion.
7984 * indent.c (Fvertical_motion): Mark locals as initialized.
7985 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
7987 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
7989 * search.c (Fre_search_backward): Mention `case-fold-search' in
7990 all the re_search_* functions (bug#8138).
7992 * keyboard.c (Fopen_dribble_file): Document when the file is
7993 closed (bug#8056).
7995 2011-07-14 Eli Zaretskii <eliz@gnu.org>
7997 * bidi.c (bidi_dump_cached_states): Fix format of displaying
7998 bidi_cache_idx.
8000 Support bidi reordering of display and overlay strings.
8001 * xdisp.c (compute_display_string_pos)
8002 (compute_display_string_end): Accept additional argument STRING.
8003 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
8004 (reseat_to_string): Initialize bidi_it->string.s and
8005 bidi_it->string.schars.
8006 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
8007 NULL (avoids a crash in bidi_paragraph_init).
8008 Initialize itb.string.lstring.
8009 (init_iterator): Call bidi_init_it only of a valid
8010 buffer position was specified. Initialize paragraph_embedding to
8011 L2R.
8012 (reseat_to_string): Initialize the bidi iterator.
8013 (display_string): If we need to ignore text properties of
8014 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
8015 original value of -1 will not work with bidi.)
8016 (compute_display_string_pos): First arg is now struct
8017 `text_pos *'; all callers changed. Support display properties on
8018 Lisp strings.
8019 (compute_display_string_end): Support display properties on Lisp
8020 strings.
8021 (init_iterator, reseat_1, reseat_to_string): Initialize the
8022 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
8023 when iterating on a string not from display properties).
8024 (compute_display_string_pos, compute_display_string_end):
8025 Fix calculation of the object to scan. Fixes an error when using
8026 arrow keys.
8027 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
8028 base_level_stop; instead, set base_level_stop to BEGV.
8029 Fixes crashes in vertical-motion.
8030 (next_element_from_buffer): Improve commentary for when
8031 the iterator is before prev_stop.
8032 (init_iterator): Initialize bidi_p from the default value of
8033 bidi-display-reordering, not from buffer-local value. Use the
8034 buffer-local value only if initializing for buffer iteration.
8035 (handle_invisible_prop): Support invisible properties on strings
8036 that are being bidi-reordered.
8037 (set_iterator_to_next): Support bidi reordering of C strings and
8038 Lisp strings.
8039 (next_element_from_string): Support bidi reordering of Lisp
8040 strings.
8041 (handle_stop_backwards): Support Lisp strings as well.
8042 (display_string): Support display of R2L glyph rows.
8043 Use IT_STRING_CHARPOS when displaying from a Lisp string.
8044 (init_iterator): Don't initialize it->bidi_p for strings

8508 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
8509 (clone_per_buffer_values): Don't assume that

8511 This isn't true in general, and it's particularly not true
8512 if Emacs is configured with --with-wide-int.
8513 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

8548 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
8550 Random fixes. E.g., (random) never returned negative values.
8551 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
8552 subseconds part to the entropy, as that's a bit more random.
8553 Prefer signed to unsigned, since the signedness doesn't matter and
8554 in general we prefer signed. When given a limit, use a
8555 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
8556 latter isn't right if USE_2_TAGS_FOR_INTS.
8557 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
8558 not 0..VALMASK. Don't discard "excess" bits that random () returns.
8560 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
8562 * textprop.c (text_property_stickiness):

8571 This is more efficient than Ffile_directory_p and avoids a minor race.
8573 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
8575 * buffer.c (Foverlay_put): Say what the return value is
8576 (bug#7835).
8578 * fileio.c (barf_or_query_if_file_exists): Check first if the file
8579 is a directory before asking whether to use the file name
8580 (bug#7564).
8581 (barf_or_query_if_file_exists): Make the "File is a directory"
8582 error be more correct.
8584 * fns.c (Frequire): Remove the mention of the .gz files, since
8585 that's installation-specific, but keep the mention of
8586 `get-load-suffixes'.
8588 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
8590 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

8600 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
8601 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
8602 Also (re)move comments that are misplaced or no longer relevant.
8604 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
8606 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

8665 (syms_of_keymap): Defsubr make-composed-keymap.
8666 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

8701 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
8703 * eval.c (struct backtrace): Simplify and port the data structure.
8704 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
8705 signed bit field, as this assumption is not portable and it makes
8706 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
8707 "char debug_on_exit : 1" as this is not portable either; instead,
8708 use the portable "unsigned int debug_on_exit : 1". Remove unused
8709 member evalargs. Remove obsolete comments about cc bombing out.
8711 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

8933 * dispnew.c (window_to_frame_vpos):
8934 * xfns.c (unwind_create_frame):
8935 * xterm.c (x_check_font): Remove unused local.
8936 * scroll.c (CHECK_BOUNDS):
8937 * xfaces.c (cache_fache): Rename local to avoid shadowing.
8938 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
8939 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
8940 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
8941 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
8942 Now static.
8943 (debug_method_add): Use va_list and vsprintf rather than relying
8944 on undefined behavior with wrong number of arguments.
8945 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
8946 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
8947 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
8948 since we're not interested in debugging glyphs with old libraries.
8949 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
8950 GCC 4.6.0's static checking.
8952 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
8954 Integer overflow and signedness fixes (Bug#8873).
8955 A few related buffer overrun fixes, too.

8960 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)
8961 (x_bitmap_mask, x_allocate_bitmap_record)
8962 (x_create_bitmap_from_data, x_create_bitmap_from_file)
8963 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
8964 (x_create_bitmap_from_xpm_data):
8965 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
8966 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
8967 (.bitmaps_last):
8968 * xfaces.c (load_pixmap):
8969 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
8970 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
8971 (.bitmaps_last, struct x_output.icon_bitmap):
8972 Use ptrdiff_t, not int, for bitmap indexes.
8973 (x_allocate_bitmap_record): Check for size overflow.
8974 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
8976 Use ptrdiff_t, not int, for overlay counts.
8977 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
8978 * editfns.c (overlays_around, get_pos_property):
8979 * textprop.c (get_char_property_and_overlay):
8980 * xdisp.c (next_overlay_change, note_mouse_highlight):
8981 * xfaces.c (face_at_buffer_position):
8982 * buffer.c (OVERLAY_COUNT_MAX): New macro.
8983 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
8984 (Fnext_overlay_change, Fprevious_overlay_change)
8985 (mouse_face_overlay_overlaps, Foverlays_in):
8986 Use ptrdiff_t, not int, for sizes.
8987 (overlays_at, overlays_in): Check for size-calculation overflow.
8989 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
8991 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
8992 (x_session_initialize): Do not assume string length fits in int.
8994 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
8995 This is unlikely, but can occur if DPI is outlandish.
8997 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
8998 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
9000 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
9001 * xrdb.c (magic_file_p, search_magic_path):
9002 Omit last arg SUFFIX; it was always 0. All callers changed.
9003 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
9005 * xfont.c (xfont_match): Avoid need for strlen.
9007 * xfns.c: Don't assume strlen fits in int.
9008 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
9010 * xdisp.c (message_log_check_duplicate): Return intmax_t,
9011 not unsigned long, as we prefer signed integers. All callers changed.
9012 Detect integer overflow in repeat count.
9013 (message_dolog): Don't assume print length fits in 39 bytes.
9014 (display_mode_element): Don't assume strlen fits in int.
9016 * termcap.c: Don't assume sizes fit in int and never overflow.
9017 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
9018 (gobble_line): Check for size-calculation overflow.
9020 * minibuf.c (Fread_buffer):
9021 * lread.c (intern, intern_c_string):
9022 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
9023 Don't assume string length fits in int.
9025 * keyboard.c (parse_tool_bar_item):
9026 * gtkutil.c (style_changed_cb): Avoid need for strlen.
9028 * font.c: Don't assume string length fits in int.
9029 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
9030 Use ptrdiff_t, not int.
9031 (font_intern_prop): Don't assume string length fits in int.
9032 Don't assume integer property fits in fixnum.
9033 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
9035 * filelock.c: Fix some buffer overrun and integer overflow issues.
9036 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
9037 Reformulate so as not to need the command string.
9038 Invoke gzip -cd rather than gunzip, as it's more portable.
9039 (lock_info_type, lock_file_1, lock_file):
9040 Don't assume pid_t and time_t fit in unsigned long.
9041 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
9042 (current_lock_owner): Prefer signed type for sizes.
9043 Use memcpy, not strncpy, where memcpy is what is really wanted.
9044 Don't assume (via atoi) that time_t and pid_t fit in int.
9045 Check for time_t and/or pid_t out of range, e.g., via a network share.
9046 Don't alloca where an auto var works fine.
9048 * fileio.c: Fix some integer overflow issues.
9049 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
9050 Don't assume string length fits in int.
9051 (directory_file_name): Don't assume string length fits in long.
9052 (make_temp_name): Don't assume pid fits in int, or that its print
9053 length is less than 20.
9055 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
9057 * coding.c (make_subsidiaries): Don't assume string length fits in int.
9059 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
9061 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
9062 We prefer signed integers, even for size calculations.
9064 * emacs.c: Don't assume string length fits in 'int'.
9065 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
9066 (main): Don't invoke strlen when not needed.
9068 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
9069 (XD_DEBUG_MESSAGE): Don't waste a byte.
9071 * callproc.c (getenv_internal_1, getenv_internal)
9072 (Fgetenv_internal):
9073 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
9075 * lread.c (invalid_syntax): Omit length argument.
9076 All uses changed. This doesn't fix a bug, but it simplifies the
9077 code away from its former Hollerith-constant appearance, and it's
9078 one less 'int' to worry about when looking at integer-overflow issues.
9079 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
9081 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
9082 This didn't break anything, but it didn't help either.
9083 It's confusing to put a bogus integer in a place where the actual
9084 value does not matter.
9085 (LIST_END_P): Remove unused macro and its bogus comment.
9086 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
9088 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
9089 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
9090 implementation.
9091 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
9092 We prefer signed types, and the value cannot exceed the EMACS_INT
9093 range anyway (because otherwise the length would not be representable).
9094 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
9095 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
9096 This avoids a GCC warning when WIDE_EMACS_INT.
9098 * indent.c (sane_tab_width): New function.
9099 (current_column, scan_for_column, Findent_to, position_indentation)
9100 (compute_motion): Use it. This is just for clarity.
9101 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
9103 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
9105 * lisp.h (lint_assume): New macro.
9106 * composite.c (composition_gstring_put_cache):
9107 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
9109 * editfns.c, insdel.c:
9110 Omit unnecessary forward decls, to simplify future changes.
9112 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
9114 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
9116 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
9117 Use much-faster test for byte-length change.
9118 Don't assume string byte-length fits in 'int'.
9119 Check that character arg fits in 'int'.
9120 (mapcar1): Declare byte as byte, for clarity.
9122 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
9124 * fns.c (concat): Catch string overflow earlier.
9125 Do not rely on integer wraparound.
9127 * dispextern.h (struct it.overlay_strings_charpos)
9128 (struct it.selective): Now EMACS_INT, not int.
9129 * xdisp.c (forward_to_next_line_start)
9130 (back_to_previous_visible_line_start)
9131 (reseat_at_next_visible_line_start, next_element_from_buffer):
9132 Don't arbitrarily truncate the value of 'selective' to int.
9134 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
9136 * composite.c: Don't truncate sizes to 'int'.
9137 (composition_gstring_p, composition_reseat_it)
9138 (composition_adjust_point): Use EMACS_INT, not int.
9139 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
9140 not EMACS_UINT, for indexes.
9142 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
9144 * buffer.c: Include <verify.h>.
9145 (struct sortvec.priority, struct sortstr.priority):
9146 Now EMACS_INT, not int.
9147 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
9148 (struct sortstr.size, record_overlay_string)
9149 (struct sortstrlist.size, struct sortlist.used):
9150 Don't truncate size to int.
9151 (record_overlay_string): Check for size-calculation overflow.
9152 (init_buffer_once): Check at compile-time, not run-time.
9154 2011-06-22 Jim Meyering <meyering@redhat.com>
9156 Don't leak an XBM-image-sized buffer
9157 * image.c (xbm_load): Free the image buffer after using it.
9159 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
9161 Port to Sun C.
9162 * composite.c (find_automatic_composition): Omit needless 'return 0;'
9163 that Sun C diagnosed.
9164 * fns.c (secure_hash): Fix pointer signedness issue.
9165 * intervals.c (static_offset_intervals): New function.
9166 (offset_intervals): Use it.
9168 2011-06-21 Leo Liu <sdl.web@gmail.com>
9170 * deps.mk (fns.o):
9171 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
9172 sha512.h.
9174 * fns.c (secure_hash): Rename from crypto_hash_function and change
9175 the first arg to accept symbols.
9176 (Fsecure_hash): New primitive.
9177 (syms_of_fns): New symbols.
9179 2011-06-20 Deniz Dogan <deniz@dogan.se>
9181 * process.c (Fset_process_buffer): Clarify return value in
9182 docstring.
9184 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
9186 * dispnew.c (add_window_display_history): Use BVAR.
9188 * xdisp.c (debug_method_add): Use BVAR.
9189 (check_window_end, dump_glyph_matrix, dump_glyph)
9190 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
9192 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
9193 Likewise.
9195 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
9196 check till after the cache is created in init_frame_faces.
9198 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
9200 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
9202 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
9204 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
9205 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
9206 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
9208 Improve buffer-overflow checking (Bug#8873).
9209 * fileio.c (Finsert_file_contents):
9210 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
9211 Remove the old (too-loose) buffer overflow checks.
9212 They weren't needed, since make_gap checks for buffer overflow.
9213 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
9214 The old code merely checked for Emacs fixnum overflow, and relied
9215 on undefined (wraparound) behavior. The new code avoids undefined
9216 behavior, and also checks for ptrdiff_t and/or size_t overflow.
9218 * editfns.c (Finsert_char): Don't dump core with very negative counts.
9219 Tune. Don't use wider integers than needed. Don't use alloca.
9220 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
9222 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
9224 * insdel.c, lisp.h (buffer_overflow): New function.
9225 (insert_from_buffer_1, replace_range, replace_range_2):
9226 * insdel.c (make_gap_larger):
9227 * editfns.c (Finsert_char):
9228 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
9230 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
9232 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
9234 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
9236 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
9237 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
9239 * fileio.c: Don't assume EMACS_INT fits in off_t.
9240 (emacs_lseek): New static function.
9241 (Finsert_file_contents, Fwrite_region): Use it.
9242 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
9244 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
9246 * fns.c: Don't overflow int when computing a list length.
9247 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
9248 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
9249 truncation on 64-bit hosts. Check for QUIT every
9250 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
9251 faster and is responsive enough.
9252 (Flength): Report an error instead of overflowing an integer.
9253 (Fsafe_length): Return a float if the value is not representable
9254 as a fixnum. This shouldn't happen except in contrived situations.
9255 (Fnthcdr, Fsort): Don't assume list length fits in int.
9256 (Fcopy_sequence): Don't assume vector length fits in int.
9258 * alloc.c: Check that resized vectors' lengths fit in fixnums.
9259 (header_size, word_size): New constants.
9260 (allocate_vectorlike): Don't check size overflow here.
9261 (allocate_vector): Check it here instead, since this is the only
9262 caller of allocate_vectorlike that could cause overflow.
9263 Check that the new vector's length is representable as a fixnum.
9265 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
9266 The previous code was bogus. For example, next_almost_prime (32)
9267 returned 39, which is undesirable as it is a multiple of 3; and
9268 next_almost_prime (24) returned 25, which is a multiple of 5 so
9269 why was the code bothering to check for multiples of 7?
9271 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
9273 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
9275 Variadic C functions now count arguments with ptrdiff_t.
9276 This partly undoes my 2011-03-30 change, which replaced int with size_t.
9277 Back then I didn't know that the Emacs coding style prefers signed int.
9278 Also, in the meantime I found a few more instances where arguments
9279 were being counted with int, which may truncate counts on 64-bit
9280 machines, or EMACS_INT, which may be unnecessarily wide.
9281 * lisp.h (struct Lisp_Subr.function.aMANY)
9282 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
9283 Arg counts are now ptrdiff_t, not size_t.
9284 All variadic functions and their callers changed accordingly.
9285 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
9286 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
9287 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
9288 * callint.c (Fcall_interactively): Check arg count for overflow,
9289 to avoid potential buffer overrun. Use signed char, not 'int',
9290 for 'varies' array, so that we needn't bother to check its size
9291 calculation for overflow.
9292 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
9293 * eval.c (apply_lambda):
9294 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
9295 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
9296 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
9298 * callint.c (Fcall_interactively): Don't use index var as event count.
9300 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
9301 * mem-limits.h (SIZE): Remove; no longer used.
9303 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
9305 Remove unnecessary casts.
9306 * xterm.c (x_term_init):
9307 * xfns.c (x_set_border_pixel):
9308 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
9309 These aren't needed now that we assume ANSI C.
9311 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
9312 It's more likely to cause problems (due to unsigned overflow)
9313 than to cure them.
9315 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
9317 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
9319 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
9321 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
9323 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
9325 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
9327 GLYPH_CODE_FACE returns EMACS_INT, not int.
9328 * dispextern.h (merge_faces):
9329 * xfaces.c (merge_faces):
9330 * xdisp.c (get_next_display_element, next_element_from_display_vector):
9331 Don't assume EMACS_INT fits in int.
9333 * character.h (CHAR_VALID_P): Remove unused parameter.
9334 * fontset.c, lisp.h, xdisp.c: All uses changed.
9336 * editfns.c (Ftranslate_region_internal): Omit redundant test.
9338 * fns.c (concat): Minor tuning based on overflow analysis.
9339 This doesn't fix any bugs. Use int to hold character, instead
9340 of constantly refetching from Emacs object. Use XFASTINT, not
9341 XINT, for value known to be a character. Don't bother comparing
9342 a single byte to 0400, as it's always less.
9344 * floatfns.c (Fexpt):
9345 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
9347 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
9348 for characters.
9350 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
9352 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
9353 Without this fix, on a 64-bit host (aset S 0 4294967386) would
9354 incorrectly succeed when S was a string, because 4294967386 was
9355 truncated before it was used.
9357 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
9358 Otherwise, an out-of-range integer could cause undefined behavior
9359 on a 64-bit host.
9361 * composite.c: Use int, not EMACS_INT, for characters.
9362 (fill_gstring_body, composition_compute_stop_pos): Use int, not
9363 EMACS_INT, for values that are known to be in character range.
9364 This doesn't fix any bugs but is the usual style inside Emacs and
9365 may generate better code on 32-bit machines.
9367 Make sure a 64-bit char is never passed to ENCODE_CHAR.
9368 This is for reasons similar to the recent CHAR_STRING fix.
9369 * charset.c (Fencode_char): Check that character arg is actually
9370 a character. Pass an int to ENCODE_CHAR.
9371 * charset.h (ENCODE_CHAR): Verify that the character argument is no
9372 wider than 'int', as a compile-time check to prevent future regressions
9373 in this area.
9375 * character.c (char_string): Remove unnecessary casts.
9377 Make sure a 64-bit char is never passed to CHAR_STRING.
9378 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
9379 by silently ignoring the top 32 bits, allowing some values
9380 that were far too large to be valid characters.
9381 * character.h: Include <verify.h>.
9382 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
9383 arguments are no wider than unsigned, as a compile-time check
9384 to prevent future regressions in this area.
9385 * data.c (Faset):
9386 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
9387 (Fsubst_char_in_region):
9388 * fns.c (concat):
9389 * xdisp.c (decode_mode_spec_coding):
9390 Adjust to CHAR_STRING's new requirement.
9391 * editfns.c (Finsert_char, Fsubst_char_in_region):
9392 * fns.c (concat): Check that character args are actually
9393 characters. Without this test, these functions did the wrong
9394 thing with wildly out-of-range values on 64-bit hosts.
9396 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
9397 These casts should not be needed on 32-bit hosts, either.
9398 * keyboard.c (read_char):
9399 * lread.c (Fload): Remove casts to unsigned.
9401 * lisp.h (UNSIGNED_CMP): New macro.
9402 This fixes comparison bugs on 64-bit hosts.
9403 (ASCII_CHAR_P): Use it.
9404 * casefiddle.c (casify_object):
9405 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
9406 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
9407 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
9408 * dispextern.h (FACE_FROM_ID):
9409 * keyboard.c (read_char): Use UNSIGNED_CMP.
9411 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
9412 not to EMACS_INT, to avoid GCC warning.
9414 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
9416 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
9417 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
9418 isn't needed on 32-bit machines.
9420 * buffer.c (Fgenerate_new_buffer_name):
9421 Use EMACS_INT for count, not int.
9422 (advance_to_char_boundary): Return EMACS_INT, not int.
9424 * data.c (Qcompiled_function): Now static.
9426 * window.c (window_body_lines): Now static.
9428 * image.c (gif_load): Rename local to avoid shadowing.
9430 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
9431 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
9432 * alloc.c (make_save_value): Integer argument is now of type
9433 ptrdiff_t, not int.
9434 (mark_object): Use ptrdiff_t, not int.
9435 * lisp.h (pD): New macro.
9436 * print.c (print_object): Use it.
9438 * alloc.c: Use EMACS_INT, not int, to count objects.
9439 (total_conses, total_markers, total_symbols, total_vector_size)
9440 (total_free_conses, total_free_markers, total_free_symbols)
9441 (total_free_floats, total_floats, total_free_intervals)
9442 (total_intervals, total_strings, total_free_strings):
9443 Now EMACS_INT, not int. All uses changed.
9444 (Fgarbage_collect): Compute overall total using a double, so that
9445 integer overflow is less likely to be a problem. Check for overflow
9446 when converting back to an integer.
9447 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
9448 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
9449 These were 'int' variables that could overflow on 64-bit hosts;
9450 they were never used, so remove them instead of repairing them.
9451 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
9452 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
9453 Previously, this ceilinged at INT_MAX, but that doesn't work on
9454 64-bit machines.
9455 (allocate_pseudovector): Don't use EMACS_INT when int would do.
9457 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
9458 (allocate_vectorlike): Check for ptrdiff_t overflow.
9459 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
9460 when a (possibly-narrower) signed value would do just as well.
9461 We prefer using signed arithmetic, to avoid comparison confusion.
9463 * alloc.c: Catch some string size overflows that we were missing.
9464 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
9465 for convenience in STRING_BYTES_MAX.
9466 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
9467 The definition here is exact; the one in lisp.h was approximate.
9468 (allocate_string_data): Check for string overflow. This catches
9469 some instances we weren't catching before. Also, it catches
9470 size_t overflow on (unusual) hosts where SIZE_MAX <= min
9471 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
9472 and ptrdiff_t and EMACS_INT are both 64 bits.
9474 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
9475 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
9476 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
9478 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
9480 * alloc.c (Fmake_string): Check for out-of-range init.
9482 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
9484 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
9486 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
9488 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
9489 xg_get_default_scrollbar_width.
9491 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.

9497 Call gtk_window_set_resizable if HAVE_GTK3.
9498 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
9499 and height if HAVE_GTK3 (Bug#8505).
9500 (scroll_bar_width_for_theme): New variable.
9501 (update_theme_scrollbar_width): New function.
9502 (xg_get_default_scrollbar_width): Move code to
9503 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.

9513 other_buffer.
9515 * window.c (temp_output_buffer_show): Call display_buffer with
9516 second argument Vtemp_buffer_show_specifiers and reset latter
9517 immediately after the call.
9518 (Vtemp_buffer_show_specifiers): New variable.
9519 (auto_window_vscroll_p, next_screen_context_lines)
9520 (Vscroll_preserve_screen_position): Remove leading asterisks from
9521 doc-strings.

10053 instead of using explicit *_CHAR codes.
10054 (bidi_resolve_explicit, bidi_resolve_weak):

10065 were just reseat()'ed to a new position.
10067 * xdisp.c (set_cursor_from_row): Set start and stop points
10068 according to the row's direction when priming the loop that looks
10069 for the glyph on which to display cursor.
10070 (single_display_spec_intangible_p): Function deleted.
10071 (display_prop_intangible_p): Reimplement to call
10072 handle_display_spec instead of single_display_spec_intangible_p.
10073 Accept 3 additional arguments needed by handle_display_spec.
10074 This fixes incorrect cursor motion across display property with complex
10075 values: lists, `(when COND...)' forms, etc.

10084 value of a `display' property is a "replacing spec".
10085 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
10086 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

10089 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
10090 frame_window_p members of struct bidi_it.
10091 (compute_display_string_pos, compute_display_string_end):

10097 * keyboard.c (adjust_point_for_property): Adjust the call to
10098 display_prop_intangible_p to its new signature.

10114 All callers changed. (Bug#8762)
10116 * gnutls.c: Use Emacs's memory allocators.
10117 Without this change, the gnutls library would invoke malloc etc.
10118 directly, which causes problems on non-SYNC_INPUT hosts, and which
10119 runs afoul of improving memory_full behavior. (Bug#8761)
10120 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
10121 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
10122 xfree instead of the default malloc, realloc, free.
10123 (Fgnutls_boot): No need to check for memory allocation failure,
10124 since xmalloc does that for us.
10126 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

10145 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
10146 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
10147 for hashes and hash indexes, instead of 'unsigned' and 'int'.
10148 * alloc.c (allocate_vectorlike):

10150 * ccl.c (ccl_driver):
10151 Check for overflow when converting EMACS_INT to int.
10152 * fns.c, image.c: Remove unnecessary static decls that would otherwise
10153 need to be updated by these changes.
10154 * fns.c (make_hash_table, maybe_resize_hash_table):
10155 Check for integer overflow with large hash tables.
10156 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
10157 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
10158 (SXHASH_REDUCE): New macro.
10159 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
10160 Use it instead of discarding useful hash info with large hash values.
10161 (sxhash_float): New function.
10162 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
10163 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
10164 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
10165 Rewrite to use FIXNUM_BITS, as this simplifies things.
10166 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
10167 Adjust signatures to match updated version of code.
10168 (consing_since_gc): Now EMACS_INT, since a single hash table can
10169 use more than INT_MAX bytes.

10218 Make it possible to run ./temacs.
10220 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,

10248 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
10250 * image.c: Various fixes to ImageMagick code comments.
10251 (Fimagemagick_types): Doc fix.
10253 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
10255 Minor fixes prompted by GCC 4.6.0 warnings.
10257 * xselect.c (converted_selections, conversion_fail_tag): Now static.
10259 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
10260 (x_clipboard_manager_save_all): Move extern decl to ...
10261 * xterm.h: ... here, so that it can be checked for consistency.
10263 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
10265 * xselect.c (x_clipboard_manager_save_frame)
10266 (x_clipboard_manager_save_all): New functions.
10267 (Fx_clipboard_manager_save): Lisp function deleted.
10269 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
10270 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
10272 * xterm.h: Update prototype.
10274 2011-05-28 William Xu <william.xwl@gmail.com>
10276 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
10277 exiting (Bug#8239).
10279 2011-05-28 Jim Meyering <meyering@redhat.com>
10281 Avoid a sign-extension bug in crypto_hash_function.
10282 * fns.c (to_uchar): Define.
10283 (crypto_hash_function): Use it to convert some newly-signed
10284 variables to unsigned, to avoid sign-extension bugs. For example,
10285 without this change, (md5 "truc") would evaluate to
10286 45723a2aff78ff4fff7fff1114760e62 rather than the expected
10287 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
10288 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
10290 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10292 Integer overflow fixes.
10294 * dbusbind.c: Serial number integer overflow fixes.
10295 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
10296 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
10297 to hold a serial number that is too large for a fixnum.
10298 (Fdbus_method_return_internal, Fdbus_method_error_internal):
10299 Check for serial numbers out of range. Decode any serial number
10300 that was so large that it became a float. (Bug#8722)
10302 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
10303 (Fdbus_call_method, Fdbus_call_method_asynchronously):
10304 Use XFASTINT rather than XUINT when numbers are nonnegative.
10305 (xd_append_arg, Fdbus_method_return_internal):
10306 (Fdbus_method_error_internal): Likewise. Also, for unsigned
10307 arguments, check that Lisp number is nonnegative, rather than
10308 silently wrapping negative numbers around. (Bug#8722)
10309 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
10310 (Bug#8722)
10312 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
10314 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
10316 ccl: Add integer overflow checks.
10317 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
10318 (IN_INT_RANGE): New macros.
10319 (ccl_driver): Use them to check for integer overflow when
10320 decoding a CCL program. Many of the new checks are whether XINT (x)
10321 fits in int; it doesn't always, on 64-bit hosts. The new version
10322 doesn't catch all possible integer overflows, but it's an
10323 improvement. (Bug#8719)
10325 * alloc.c (make_event_array): Use XINT, not XUINT.
10326 There's no need for unsigned here.
10328 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
10329 This follows up to the 2011-05-06 change that substituted uintptr_t
10330 for EMACS_INT. This case wasn't caught back then.
10332 Rework Fformat to avoid integer overflow issues.
10333 * editfns.c: Include <float.h> unconditionally, as it's everywhere
10334 now (part of C89). Include <verify.h>.
10335 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
10336 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
10337 (Fformat): Avoid the prepass trying to compute sizes; it was only
10338 approximate and thus did not catch overflow reliably. Instead, walk
10339 through the format just once, formatting and computing sizes as we go,
10340 checking for integer overflow at every step, and allocating a larger
10341 buffer as needed. Keep track separately whether the format is
10342 multibyte. Keep only the most-recently calculated precision, rather
10343 than them all. Record whether each argument has been converted to
10344 string. Use EMACS_INT, not int, for byte and char and arg counts.
10345 Support field widths and precisions larger than INT_MAX. Avoid
10346 sprintf's undefined behavior with conversion specifications such as %#d
10347 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
10348 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
10349 formatting out-of-range floating point numbers with int
10350 formats. (Bug#8668)
10352 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
10354 * data.c: Avoid integer truncation in expressions involving floats.
10355 * data.c: Include <intprops.h>.
10356 (arith_driver): When there's an integer overflow in an expression
10357 involving floating point, convert the integers to floating point
10358 so that the resulting value does not suffer from catastrophic
10359 integer truncation. For example, on a 64-bit host (* 4
10360 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
10361 Do not rely on undefined behavior after integer overflow.
10363 merge count_size_as_multibyte, parse_str_to_multibyte
10364 * character.c, character.h (count_size_as_multibyte):
10365 Rename from parse_str_to_multibyte; all uses changed.
10366 Check for integer overflow.
10367 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
10368 since it's now a duplicate of the other. This is more of
10369 a character than a buffer op, so better that it's in character.c.
10370 * fns.c, print.c: Adjust to above changes.
10372 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
10374 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
10376 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10378 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10379 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
10380 (x_clipboard_manager_save): Now static.
10381 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
10383 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10384 (crypto_hash_function): Now static.
10385 Fix pointer signedness problems. Avoid unnecessary initializations.
10387 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
10389 * termhooks.h (Vselection_alist): Make it terminal-local.
10391 * terminal.c (create_terminal): Initialize it.
10393 * xselect.c: Support for clipboard managers.
10394 (Vselection_alist): Move to termhooks.h as terminal-local var.
10395 (LOCAL_SELECTION): New macro.
10396 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
10397 (symbol_to_x_atom): Remove gratuitous arg.
10398 (x_handle_selection_request, lisp_data_to_selection_data)
10399 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
10400 (x_own_selection, x_get_local_selection, x_convert_selection):
10401 New arg, specifying work frame. Use terminal-local Vselection_alist.
10402 (some_frame_on_display): Delete unused function.
10403 (Fx_own_selection_internal, Fx_get_selection_internal)
10404 (Fx_disown_selection_internal, Fx_selection_owner_p)
10405 (Fx_selection_exists_p): New optional frame arg.
10406 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
10407 (x_handle_selection_clear): Don't treat other terminals with the
10408 same keyboard specially. Use the terminal-local Vselection_alist.
10409 (x_clear_frame_selections): Use Frun_hook_with_args.
10411 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
10413 * xterm.h: Add support for those atoms.
10415 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
10417 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
10418 (converted_selections, conversion_fail_tag): New global variables.
10419 (x_selection_request_lisp_error): Free the above.
10420 (x_get_local_selection): Remove unnecessary code.
10421 (x_reply_selection_request): Args changed; handle arbitrary array
10422 of converted selections stored in converted_selections.
10423 Separate the XChangeProperty and SelectionNotify steps.
10424 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
10425 (x_convert_selection): New function.
10426 (x_handle_selection_event): Simplify.
10427 (x_get_foreign_selection): Don't ignore incoming requests while
10428 waiting for an answer; this will fail when we implement
10429 SAVE_TARGETS, and seems unnecessary anyway.
10430 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
10431 (Vx_sent_selection_functions): Doc fix.
10433 2011-05-26 Leo Liu <sdl.web@gmail.com>
10435 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
10437 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10439 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
10441 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
10442 for fringe update if it has periodic bitmap.
10443 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
10444 and fringe_bitmap_periodic_p.
10446 * fringe.c (get_fringe_bitmap_data): New function.
10447 (draw_fringe_bitmap_1, update_window_fringes): Use it.
10448 (update_window_fringes): Record periodicity of fringe bitmap in glyph
10449 row. Mark glyph row for fringe update if periodicity changed.
10451 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
10452 for fringe update unless it has periodic bitmap.
10454 2011-05-25 Kenichi Handa <handa@m17n.org>
10456 * xdisp.c (get_next_display_element): Set correct it->face_id for
10457 a static composition.
10459 2011-05-24 Leo Liu <sdl.web@gmail.com>
10461 * deps.mk (fns.o):
10462 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
10464 * fns.c (crypto_hash_function, Fsha1): New function.
10465 (Fmd5): Use crypto_hash_function.
10466 (syms_of_fns): Add Ssha1.
10468 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
10470 * gnutls.c: Remove unused macros.
10471 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
10472 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
10473 Remove macros that are defined and never used.
10474 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
10476 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10478 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
10479 (Fx_get_selection_internal): Minor cleanup.
10480 (Fx_own_selection_internal): Rename arguments for consistency with
10481 select.el.
10483 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
10485 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
10487 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10489 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
10491 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10493 * dispnew.c (scrolling_window): Don't exclude the case that the
10494 last enabled row in the desired matrix touches the bottom boundary.
10496 2011-05-21 Glenn Morris <rgm@gnu.org>
10498 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
10499 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
10500 and add some more files.
10502 2011-05-20 Eli Zaretskii <eliz@gnu.org>
10504 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
10505 report_file_error introduced by the change from 2011-05-07.
10507 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
10509 * systime.h (Time): Define only if emacs is defined.
10510 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
10511 where the include path doesn't have X11/X.h by default. See
10512 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
10514 2011-05-20 Kenichi Handa <handa@m17n.org>
10516 * composite.c (find_automatic_composition): Fix previous change.
10518 2011-05-20 Glenn Morris <rgm@gnu.org>
10520 * lisp.mk: New file, split from Makefile.in.
10521 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
10522 (shortlisp): Remove.
10523 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
10525 2011-05-19 Glenn Morris <rgm@gnu.org>
10527 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
10528 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
10529 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
10530 (lisp): Set the order to that of loadup.el.
10531 (shortlisp): Make it a copy of $lisp.
10532 (SOME_MACHINE_LISP): Remove.
10533 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
10534 Use just $shortlisp, not $SOME_MACHINE_LISP too.
10536 2011-05-18 Kenichi Handa <handa@m17n.org>
10538 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
10539 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
10540 (find_automatic_composition): Mostly rewrite for efficiency.
10542 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
10544 * makefile.w32-in: Update dependencies.
10546 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
10548 * menu.c: Include limits.h (fixes the MS-Windows build broken by
10549 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
10551 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
10553 Fix some integer overflow issues, such as string length overflow.
10555 * insdel.c (count_size_as_multibyte): Check for string overflow.
10557 * character.c (lisp_string_width): Check for string overflow.
10558 Use EMACS_INT, not int, for string indexes and lengths; in
10559 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
10560 the resulting string length overflows an EMACS_INT; instead,
10561 report a string overflow if no precision given. When checking for
10562 precision exhaustion, use a check that cannot possibly have
10563 integer overflow. (Bug#8675)
10564 * character.h (lisp_string_width): Adjust to new signature.
10566 * alloc.c (string_overflow): New function.
10567 (Fmake_string): Use it. This doesn't change behavior, but saves
10568 a few bytes and will simplify future changes.
10569 * character.c (string_escape_byte8): Likewise.
10570 * lisp.h (string_overflow): New decl.
10572 Fixups, following up to the user-interface timestamp change.
10573 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
10574 for UI timestamps, instead of unsigned long.
10575 * msdos.c (mouse_get_pos): Likewise.
10576 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
10577 * w32gui.h (Time): Define by including "systime.h" rather than by
10578 declaring it ourselves. (Bug#8664)
10580 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
10581 * image.c (clear_image_cache): Likewise.
10583 * term.c (term_mouse_position): Don't assume time_t wraparound.
10585 Be more systematic about user-interface timestamps.
10586 Before, the code sometimes used 'Time', sometimes 'unsigned long',
10587 and sometimes 'EMACS_UINT', to represent these timestamps.
10588 This change causes it to use 'Time' uniformly, as that's what X uses.
10589 This makes the code easier to follow, and makes it easier to catch
10590 integer overflow bugs such as Bug#8664.
10591 * frame.c (Fmouse_position, Fmouse_pixel_position):
10592 Use Time, not unsigned long, for user-interface timestamps.
10593 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
10594 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
10595 * keyboard.h (last_event_timestamp): Likewise.
10596 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
10597 * menu.h (xmenu_show): Likewise.
10598 * term.c (term_mouse_position): Likewise.
10599 * termhooks.h (struct input_event.timestamp): Likewise.
10600 (struct terminal.mouse_position_hook): Likewise.
10601 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
10602 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
10603 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
10604 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
10605 what it was before.
10606 * menu.h, termhooks.h: Include "systime.h", for Time.
10608 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
10609 Don't assume that the difference between two unsigned long values
10610 can fit into an integer. At this point, we know button_down_time
10611 <= event->timestamp, so the difference must be nonnegative, so
10612 there's no need to cast the result if double-click-time is
10613 nonnegative, as it should be; check that it's nonnegative, just in
10614 case. This bug is triggered when events are more than 2**31 ms
10615 apart (about 25 days). (Bug#8664)
10617 * xselect.c (last_event_timestamp): Remove duplicate decl.
10618 (x_own_selection): Remove needless cast to unsigned long.
10620 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
10621 that always fit in int. Use a sentinel instead of a counter, to
10622 avoid a temp and to allay GCC's concerns about possible int overflow.
10623 * frame.h (struct frame): Use int for menu_bar_items_used
10624 instead of EMACS_INT, since it always fits in int.
10626 * menu.c (grow_menu_items): Check for int overflow.
10628 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
10630 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
10631 Before, the code was not consistent. These values cannot exceed
10632 2**31 - 1 so there's no need to make them unsigned.
10633 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
10634 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
10635 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
10636 as modifiers.
10637 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
10639 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
10640 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
10641 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
10642 presumably because the widths might not match.
10644 * window.c (size_window): Avoid needless test at loop start.
10646 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
10648 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
10650 2011-05-12 Drew Adams <drew.adams@oracle.com>
10652 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
10654 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10656 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
10657 `width' to `bar_area_x' and `bar_area_width', respectively.
10658 (x_scroll_run): Take account of fringe background extension.
10660 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
10661 Rename local vars `left' and `width' to `bar_area_x' and
10662 `bar_area_width', respectively.
10663 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
10664 background extension.
10666 2011-05-10 Jim Meyering <meyering@redhat.com>
10668 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
10670 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
10672 * image.c (Finit_image_library): Return t for built-in image types,
10673 like pbm and xbm. (Bug#8640)
10675 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
10677 * w32menu.c (set_frame_menubar): Fix submenu allocation.
10679 2011-05-07 Eli Zaretskii <eliz@gnu.org>
10681 * w32console.c (Fset_screen_color): Doc fix.
10682 (Fget_screen_color): New function.
10683 (syms_of_ntterm): Defsubr it.
10685 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
10686 unlink the temporary file if Fcall_process didn't create it in the
10687 first place.
10688 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
10689 child process will be redirected to a file specified with `:file'.
10690 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
10691 cue to call_process_cleanup not to close that handle.
10693 2011-05-07 Ben Key <bkey76@gmail.com>
10695 * makefile.w32-in: The bootstrap-temacs rule now makes use of
10696 one of two shell specific rules, either bootstrap-temacs-CMD or
10697 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
10698 to the previous implementation of the bootstrap-temacs rule.
10699 The bootstrap-temacs-CMD rule is similar to the previous
10700 implementation of the bootstrap-temacs rule except that it
10701 makes use of the ESC_CFLAGS variable instead of the CFLAGS
10702 variable.
10704 These changes, along with some changes to nt/configure.bat,
10705 nt/gmake.defs, and nt/nmake.defs, are required to extend my
10706 earlier fix to add support for --cflags and --ldflags options
10707 that include quotes so that it works whether make uses cmd or
10708 sh as the shell.
10710 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
10712 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
10713 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
10714 is a constant.
10715 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
10716 a string. Handle both cases.
10717 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
10718 (Fdbus_register_method): Use Qinvalid_function.
10720 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
10722 * makefile.w32-in: Update dependencies.
10723 (LISP_H): Add inttypes.h and stdin.h.
10724 (PROCESS_H): Add unistd.h.
10726 2011-05-06 Eli Zaretskii <eliz@gnu.org>
10728 * lread.c: Include limits.h (fixes the MS-Windows build broken by
10729 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
10731 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
10733 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
10735 * term.c (vfatal): Remove stray call to va_end.
10736 It's not needed and the C Standard doesn't allow it here anyway.
10738 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
10739 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
10741 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
10742 bytes.
10744 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
10746 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
10748 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
10750 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
10752 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
10754 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
10755 * charset.c (Fdefine_charset_internal): Don't initialize
10756 charset.code_space[15]. The value was garbage, on hosts with
10757 32-bit int (Bug#8600).
10759 * lread.c (read_integer): Be more consistent with string-to-number.
10760 Use string_to_number to do the actual conversion; this avoids
10761 rounding errors and fixes some other screwups. Without this fix,
10762 for example, #x1fffffffffffffff was misread as -2305843009213693952.
10763 (digit_to_number): Move earlier, for benefit of read_integer.
10764 Return -1 if the digit is out of range for the base, -2 if it is
10765 not a digit in any supported base. (Bug#8602)
10767 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
10769 * dispnew.c (scrolling_window): Return 1 if we scrolled,
10770 to match comment at start of function. This also removes a
10771 GCC warning about overflow in a 32+64-bit port.
10773 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
10775 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
10776 Reported by Stefan Monnier in
10777 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
10778 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
10779 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
10781 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
10782 (EMACS_UINTPTR): Likewise, with uintptr_t.
10784 * lisp.h: Prefer 64-bit EMACS_INT if available.
10785 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
10786 on 32-bit hosts that have 64-bit int, so that they can access
10787 large files.
10788 However, temporarily disable this change unless the temporary
10789 symbol WIDE_EMACS_INT is defined.
10791 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
10793 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
10794 This removes an assumption that EMACS_INT and long are the same
10795 width as pointers. The assumption is true for Emacs porting targets
10796 now, but we want to make other targets possible.
10797 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
10798 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
10799 In the rest of the code, change types of integers that hold casted
10800 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
10801 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
10802 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
10803 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
10804 No need to cast type when ORing.
10805 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
10806 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
10807 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
10808 assume EMACS_INT is the same width as char *.
10809 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
10810 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
10811 Remove no-longer-needed casts.
10812 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
10813 (xg_tool_bar_help_callback, xg_make_tool_item):
10814 Use EMACS_INTPTR to hold an integer
10815 that will be cast to void *; this can avoid a GCC warning
10816 if EMACS_INT is not the same width as void *.
10817 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
10818 * xdisp.c (display_echo_area_1, resize_mini_window_1):
10819 (current_message_1, set_message_1):
10820 Use a local to convert to proper width without a cast.
10821 * xmenu.c (dialog_selection_callback): Likewise.
10823 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
10824 Also, don't assume VALBITS / RAND_BITS is less than 5,
10825 and don't rely on undefined behavior when shifting a 1 left into
10826 the sign bit.
10827 * lisp.h (get_random): Change signature to match.
10829 * lread.c (hash_string): Use size_t, not int, for hash computation.
10830 Normally we prefer signed values; but hashing is special, because
10831 it's better to use unsigned division on hash table sizes so that
10832 the remainder is nonnegative. Also, size_t is the natural width
10833 for hashing into memory. The previous code used 'int', which doesn't
10834 retain enough info to hash well into very large tables.
10835 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
10837 * dbusbind.c: Don't possibly lose pointer info when converting.
10838 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
10839 Use XPNTR rather than XHASH, so that the high-order bits of
10840 the pointer aren't lost when converting through void *.
10842 * eval.c (Fautoload): Don't double-shift a pointer.
10844 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
10846 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
10848 * gnutls.c (DEF_GNUTLS_FN):
10849 * image.c (DEF_IMGLIB_FN): Make function pointers static.
10851 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
10853 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
10854 marker. (Bug#8610)
10856 2011-05-05 Eli Zaretskii <eliz@gnu.org>
10858 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
10859 New version that can reserve upto 2GB of heap space.
10861 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
10863 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
10865 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
10867 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
10868 `gnutls_certificate_set_x509_key_file'.
10870 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
10872 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
10873 Update dependencies.
10875 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
10877 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
10878 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
10879 Remove unused parameter `fildes'.
10880 * process.c (read_process_output, send_process): Don't pass it.
10882 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
10884 Fix previous change: the library cache is defined in w32.c.
10885 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
10886 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
10888 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
10890 Implement dynamic loading of GnuTLS on Windows.
10892 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
10893 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
10894 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
10895 Declare.
10897 * gnutls.c (Qgnutls_dll): Define.
10898 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
10899 (gnutls_*): Declare function pointers.
10900 (init_gnutls_functions): New function to initialize function pointers.
10901 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
10902 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
10903 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
10904 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
10905 (emacs_gnutls_write, emacs_gnutls_read)
10906 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
10907 (Fgnutls_available_p): New function.
10908 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
10909 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
10910 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
10912 * image.c: Include w32.h.
10913 (Vimage_type_cache): Delete.
10914 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
10915 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
10916 (w32_delayed_load): Move to w32.c.
10918 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
10920 * w32.c (QCloaded_from, Vlibrary_cache): Define.
10921 (w32_delayed_load): Move from image.c. When loading a library, record
10922 its filename in the :loaded-from property of the library id.
10923 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
10924 Initialize and staticpro them.
10925 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
10927 * process.c: Include lisp.h before w32.h, not after.
10928 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
10929 instead of gnutls_record_check_pending.
10931 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
10933 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
10935 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
10936 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
10937 as passed in.
10939 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
10941 * xterm.c (x_set_frame_alpha): Do not set property on anything
10942 else than FRAME_X_OUTER_WINDOW (Bug#8608).
10944 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
10946 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
10948 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
10950 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
10951 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

10957 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
10958 (Qgnutls_bootprop_callbacks_verify): Make static.
10960 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
10962 * callproc.c: Indentation fixup.
10964 * sysdep.c (wait_for_termination_1): Make static.
10965 (wait_for_termination, interruptible_wait_for_termination):
10966 Move after wait_for_termination_1.
10968 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
10970 * sysdep.c (interruptible_wait_for_termination): New function
10971 which is like wait_for_termination, but allows keyboard
10972 interruptions.
10974 * callproc.c (Fcall_process): Add (:file "file") as an option for
10975 the STDOUT buffer.
10976 (Fcall_process_region): Ditto.
10978 2011-04-30 Eli Zaretskii <eliz@gnu.org>
10980 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
10981 rather than `XVECTOR (FOO)->size'.
10983 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
10984 inttypes.h, as a gnulib replacement is used if it not available in
10985 system headers.
10987 2011-04-21 Eli Zaretskii <eliz@gnu.org>
10989 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
10990 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
10991 of MOST_POSITIVE_FIXNUM. (Bug#8528)
10993 * coding.c (coding_alloc_by_realloc): Error out if destination
10994 will grow beyond MOST_POSITIVE_FIXNUM.
10995 (decode_coding_emacs_mule): Abort if there isn't enough place in
10996 charbuf for the composition carryover bytes. Reserve an extra
10997 space for up to 2 characters produced in a loop.
10998 (decode_coding_iso_2022): Abort if there isn't enough place in
10999 charbuf for the composition carryover bytes.
11001 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11003 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
11004 aborting when %lld or %lll format is passed.
11005 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
11006 %llo or %llx format is passed. (Bug#8545)
11008 * window.c (window_scroll_line_based): Use a marker instead of
11009 simple variables to record original value of point. (Bug#7952)
11011 * doprnt.c (doprnt): Fix the case where a multibyte sequence
11012 produced by %s or %c overflows available buffer space. (Bug#8545)
11014 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
11016 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
11017 (SIZE_MAX): Move defn after all includes, as they might #define it.
11019 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11021 * w32.c (init_environment): Warn about defaulting HOME to C:\.

11026 (command_loop_1): Run `delayed-warnings-hook'
11027 if Vdelayed_warnings_list is non-nil.
11028 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
11029 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
11031 2011-04-28 Eli Zaretskii <eliz@gnu.org>
11033 * doprnt.c (doprnt): Don't return value smaller than the buffer
11034 size if the message was truncated. (Bug#8545).
11036 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11038 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
11039 (Fx_window_property): #if-0 the whole functions, not just the bodies.
11041 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11043 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
11045 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
11047 * makefile.w32-in: Update dependencies.
11049 2011-04-27 Eli Zaretskii <eliz@gnu.org>
11051 Improve `doprnt' and its usage. (Bug#8545)
11052 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
11053 `format_end'. Remove support for %l as a conversion specifier.
11054 Don't use xrealloc. Improve diagnostics when the %l size modifier
11055 is used. Update the commentary.
11057 * eval.c (verror): Simplify calculation of size_t.
11059 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
11060 messages.
11062 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
11064 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
11065 change.
11067 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11069 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
11070 This makes this file independent of the recent pseudovector change.
11072 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
11074 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
11076 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
11077 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
11078 Remove unused local.
11079 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
11081 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
11082 GCC 4.6.0 optimizes based on type-based alias analysis.
11083 For example, if b is of type struct buffer * and v of type struct
11084 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
11085 != &v->size, and therefore "v->size = 1; b->size = 2; return
11086 v->size;" must therefore return 1. This assumption is incorrect
11087 for Emacs, since it type-puns struct Lisp_Vector * with many other
11088 types. To fix this problem, this patch adds a new type struct
11089 vectorlike_header that documents the constraints on layout of vectors
11090 and pseudovectors, and helps optimizing compilers not get fooled
11091 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
11092 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
11093 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
11094 the size member.
11095 (XSETPVECTYPE): Rewrite in terms of new macro.
11096 (XSETPVECTYPESIZE): New macro, specifying both type and size.
11097 This is a bit clearer, and further avoids the possibility of
11098 undesirable aliasing.
11099 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
11100 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
11101 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
11102 since Lisp_Subr is a special case (no "next" field).
11103 (ASIZE): Now uses header.size rather than size.
11104 All previous uses of XVECTOR (foo)->size replaced to use this macro,
11105 to avoid the hassle of writing XVECTOR (foo)->header.size.
11106 (struct vectorlike_header): New type.
11107 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
11108 object, to help avoid aliasing.
11109 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
11110 (SUBRP): Likewise, since Lisp_Subr is a special case.
11111 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
11112 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
11113 (struct Lisp_Hash_Table): Combine first two members into a single
11114 struct vectorlike_header member. All uses of "size" and "next" members
11115 changed to be "header.size" and "header.next".
11116 * buffer.h (struct buffer): Likewise.
11117 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
11118 * frame.h (struct frame): Likewise.
11119 * process.h (struct Lisp_Process): Likewise.
11120 * termhooks.h (struct terminal): Likewise.
11121 * window.c (struct save_window_data, struct saved_window): Likewise.
11122 * window.h (struct window): Likewise.
11123 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
11124 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
11125 * buffer.c (init_buffer_once): Likewise.
11126 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
11127 special case.
11128 * process.c (Fformat_network_address): Use local var for size,
11129 for brevity.
11131 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
11133 Make the Lisp reader and string-to-float more consistent (Bug#8525)
11134 * data.c (atof): Remove decl; no longer used or needed.
11135 (digit_to_number): Move to lread.c.
11136 (Fstring_to_number): Use new string_to_number function, to be
11137 consistent with how the Lisp reader treats infinities and NaNs.
11138 Do not assume that floating-point numbers represent EMACS_INT
11139 without losing information; this is not true on most 64-bit hosts.
11140 Avoid double-rounding errors, by insisting on integers when
11141 parsing non-base-10 numbers, as the documentation specifies.
11142 * lisp.h (string_to_number): New decl, replacing ...
11143 (isfloat_string): Remove.
11144 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
11145 (read1): Do not accept +. and -. as integers; this
11146 appears to have been a coding error. Similarly, do not accept
11147 strings like +-1e0 as floating point numbers. Do not report
11148 overflow for integer overflows unless the base is not 10 which
11149 means we have no simple and reliable way to continue.
11150 Break out the floating-point parsing into a new
11151 function string_to_number, so that Fstring_to_number parses
11152 floating point numbers consistently with the Lisp reader.
11153 (digit_to_number): Move here from data.c. Make it static inline.
11154 (E_CHAR, EXP_INT): Remove, replacing with ...
11155 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
11156 (string_to_number): New function, replacing isfloat_string.
11157 This function checks for valid syntax and produces the resulting
11158 Lisp float number too. Rework it so that string-to-number
11159 no longer mishandles examples like "1.0e+". Use strtoumax,
11160 so that overflow for non-base-10 numbers is reported only when
11161 there's no portable and simple way to convert to floating point.
11163 * textprop.c (set_text_properties_1): Rewrite for clarity,
11164 and to avoid GCC warning about integer overflow.
11166 * intervals.h (struct interval): Use EMACS_INT for members
11167 where EMACS_UINT might cause problems. See
11168 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
11169 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
11170 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
11171 All uses changed.
11172 (offset_intervals): Tell GCC not to worry about length overflow
11173 when negating a negative length.
11175 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
11176 (overrun_check_free): Likewise.
11178 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
11179 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
11180 word size.
11182 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11183 (gnutls_make_error): Rename local to avoid shadowing.
11184 (gnutls_emacs_global_deinit): ifdef out; not used.
11185 (Fgnutls_boot): Use const for pointer to readonly storage.
11186 Comment out unused local. Fix pointer signedness problems.
11188 * lread.c (openp): Don't stuff size_t into an 'int'.
11189 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
11190 about possible signed overflow.
11192 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11193 (GDK_KEY_g): Don't define if already defined.
11194 (xg_prepare_tooltip): Avoid pointer signedness problem.
11195 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
11197 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
11198 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
11200 * xfns.c (Fx_window_property): Simplify a bit,
11201 to make a bit faster and to avoid GCC 4.6.0 warning.
11202 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
11204 * fns.c (internal_equal): Don't assume size_t fits in int.
11206 * alloc.c (compact_small_strings): Tighten assertion a little.
11208 Replace pEd with more-general pI, and fix some printf arg casts.
11209 * lisp.h (pI): New macro, generalizing old pEd macro to other
11210 conversion specifiers. For example, use "...%"pI"d..." rather
11211 than "...%"pEd"...".
11212 (pEd): Remove. All uses replaced with similar uses of pI.
11213 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
11214 * alloc.c (check_pure_size): Don't overflow by converting size to int.
11215 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
11216 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
11217 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
11218 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
11219 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
11220 64-bit hosts.
11221 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
11222 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
11223 * print.c (safe_debug_print, print_object): Likewise.
11224 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
11225 to int.
11226 Use pI instead of if-then-else-abort. Use %p to avoid casts,
11227 avoiding the 0 flag, which is not portable.
11228 * process.c (Fmake_network_process): Use pI to avoid cast.
11229 * region-cache.c (pp_cache): Likewise.
11230 * xdisp.c (decode_mode_spec): Likewise.
11231 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
11232 behavior on 64-bit hosts with printf arg.
11233 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
11234 (x_stop_queuing_selection_requests): Likewise.
11235 (x_get_window_property): Don't truncate byte count to an 'int'
11236 when tracing.
11238 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
11239 here, since it parses constructs like leading '-' and spaces,
11240 which are not wanted; and it overflows with large numbers.
11241 Instead, simply match F[0-9]+, which is what is wanted anyway.
11243 * alloc.c: Remove unportable assumptions about struct layout.
11244 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
11245 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
11246 (allocate_vectorlike, make_pure_vector): Use the new macros,
11247 plus offsetof, to remove unportable assumptions about struct layout.
11248 These assumptions hold on all porting targets that I know of, but
11249 they are not guaranteed, they're easy to remove, and removing them
11250 makes further changes easier.
11252 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
11253 This doesn't fix a bug but makes the code clearer.
11254 (string_overrun_cookie): Now const. Use initializers that
11255 don't formally overflow signed char, to avoid warnings.
11256 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
11257 can cause Emacs to crash when string overrun checking is enabled.
11258 (allocate_buffer): Don't assume sizeof (struct buffer) is a
11259 multiple of sizeof (EMACS_INT); it need not be, if
11260 alignof(EMACS_INT) < sizeof (EMACS_INT).
11261 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
11263 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
11265 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
11267 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
11269 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
11270 supposed to be handshaking. (Bug#8556)
11271 Reported by Paul Eggert <eggert@cs.ucla.edu>.
11273 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
11275 * lisp.h (Qdebug): List symbol.
11276 * eval.c (Qdebug): Restore global linkage.
11277 * keyboard.c (debug-on-event): New variable.
11278 (handle_user_signal): Break into debugger when debug-on-event
11279 matches the current signal symbol.
11281 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
11283 * alloc.c (check_sblock, check_string_bytes)
11284 (check_string_free_list): Convert to standard C.
11286 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
11288 * w32.c (emacs_gnutls_push): Fix typo.
11290 2011-04-25 Eli Zaretskii <eliz@gnu.org>
11292 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
11293 "cast to pointer from integer of different size".
11295 Improve doprnt and its use in verror. (Bug#8545)
11296 * doprnt.c (doprnt): Document the set of format control sequences
11297 supported by the function. Use SAFE_ALLOCA instead of always
11298 using `alloca'.
11300 * eval.c (verror): Don't limit the buffer size at size_max-1, that
11301 is one byte too soon. Don't use xrealloc; instead xfree and
11302 xmalloc anew.
11304 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
11306 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
11307 callbacks stage.
11309 * gnutls.c: Renamed global_initialized to
11310 gnutls_global_initialized. Added internals for the
11311 :verify-hostname-error, :verify-error, and :verify-flags
11312 parameters of `gnutls-boot' and documented those parameters in the
11313 docstring. Start callback support.
11314 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
11315 unless a fatal error occurred. Call gnutls_alert_send_appropriate
11316 on error. Return error code.
11317 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
11318 (emacs_gnutls_read): Likewise.
11319 (Fgnutls_boot): Return handshake error code.
11320 (emacs_gnutls_handle_error): New function.

11324 (emacs_gnutls_push): Likewise.
11326 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
11327 (emacs_gnutls_push): Likewise.

11331 * process.c (wait_reading_process_output): Check if GnuTLS
11332 buffered some data internally if no FDs are set for TLS
11333 connections.

11344 commentary.
11346 * textprop.c (syms_of_textprop): Remove dead code.
11347 (copy_text_properties): Delete obsolete commentary about an
11348 interface that was deleted long ago. Fix typos in the description
11349 of arguments.

11352 to changes in oldXMenu/XMenu.h from 2011-04-16.
11353 <menu_help_message, prev_menu_help_message>: Constify.
11354 (IT_menu_make_room): menu->help_text is now `const char **';
11355 adjust.

11358 to changes in oldXMenu/XMenu.h from 2011-04-16.
11359 (struct XMenu): Declare `help_text' `const char **'.
11361 * xfaces.c <Qunspecified>: Make extern again.
11363 * syntax.c: Include sys/types.h before including regex.h, as
11364 required by POSIX.

11368 * doprnt.c (doprnt): Improve commentary.
11370 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
11372 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
11373 them with etags.
11375 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
11376 changes in globals.h immediately force recompilation.
11377 (TAGS): Depend on $(CURDIR)/m/intel386.h and
11378 $(CURDIR)/s/ms-w32.h.
11379 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.
11381 * character.c (Fchar_direction): Function deleted.
11382 (syms_of_character): Don't defsubr it.
11383 <char-direction-table>: Deleted.
11385 2011-04-23 Eli Zaretskii <eliz@gnu.org>
11387 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
11388 * doprnt.c: Include limits.h.
11389 (SIZE_MAX): New macro.
11390 (doprnt): Return a size_t value. 2nd arg is now size_t.
11391 Many local variables are now size_t instead of int or unsigned.
11392 Improve overflow protection. Support `l' modifier for integer
11393 conversions. Support %l conversion. Don't assume an EMACS_INT
11394 argument for integer conversions and for %c.
11396 * lisp.h (doprnt): Restore prototype.
11398 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
11399 $(SRC)/character.h.
11401 * Makefile.in (base_obj): Add back doprnt.o.
11403 * deps.mk (doprnt.o): Add back prerequisites.
11404 (callint.o): Depend on character.h.
11406 * eval.c (internal_lisp_condition_case): Include the handler
11407 representation in the error message.
11408 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
11409 when breaking from the loop.
11411 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
11413 * callint.c (Fcall_interactively): When displaying error message
11414 about invalid control letter, pass the character's codepoint, not
11415 a pointer to its multibyte form. Improve display of the character
11416 in octal and display also its hex code.
11418 * character.c (char_string): Use %x to display the (unsigned)
11419 codepoint of an invalid character, to avoid displaying a bogus
11420 negative value.
11422 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
11423 `error', not SYMBOL_NAME itself.
11425 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
11426 character arguments to `error'.
11428 * charset.c (check_iso_charset_parameter): Fix incorrect argument
11429 to `error' in error message about FINAL_CHAR argument. Make sure
11430 FINAL_CHAR is a character, and use %c when it is passed as
11431 argument to `error'.
11433 2011-04-23 Eli Zaretskii <eliz@gnu.org>
11435 * s/ms-w32.h (localtime): Redirect to sys_localtime.
11437 * w32.c: Include <time.h>.

11457 to <= INT_MAX.
11459 2011-04-18 Chong Yidong <cyd@stupidchicken.com>

11492 * data.c (arith_error): Mark with NO_RETURN if it doesn't return.
11494 * alloc.c (bytes_used_when_full, SPARE_MEMORY, BYTES_USED):
11495 Define only if needed.
11497 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
11498 by pacifying GCC about it. Maybe it's time to retire it?
11499 * xfaces.c (USG, __TIMEVAL__): Likewise.
11501 * dispextern.h (struct redisplay_interface): Rename param
11502 to avoid shadowing.
11503 * termhooks.h (struct terminal): Likewise.
11504 * xterm.c (xembed_send_message): Likewise.
11506 * insdel.c (make_gap_smaller): Define only if
11507 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
11509 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
11510 it.
11512 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
11513 so that we aren't warned about unused symbols.
11515 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
11517 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
11519 * xfns.c (x_real_positions): Mark locals as initialized.
11521 * xmenu.c (xmenu_show): Don't use uninitialized vars.
11523 * xterm.c: Fix problems found by static analysis with other toolkits.
11524 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
11525 (x_dispatch_event): Declare static if USE_GTK, and
11526 define if USE_GTK || USE_X_TOOLKIT.
11527 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
11528 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.

11530 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
11532 * xmenu.c (menu_help_callback): Pointer type fixes.

11534 signedness clashes.
11535 (FALSE): Remove unused macro.
11536 (update_frame_menubar): Remove unused decl.
11538 * xfns.c (Fx_hide_tip): Move locals to avoid shadowing.

11620 * nsfont.m: Fixed bugs in ns_get_family and
11621 ns_descriptor_to_entity that were caused by using free to
11622 deallocate memory blocks that were allocated by xmalloc (via
11623 xstrdup). This caused Emacs to crash when compiled with
11624 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
11625 --enable-checking=xmallocoverrun). xfree is now used to
11626 deallocate these memory blocks.

11962 * charset.h (charset_iso_8859_1): Remove decl.
11963 * charset.c (charset_iso_8859_1, charset_emacs, map_charset_for_dump):
11964 Now static.
11966 * ccl.h (check_ccl_update, Vccl_program_table): Remove decls.
11967 * ccl.c (Vccl_program_table): Now static.
11968 (check_ccl_update): Remove; unused.
11970 * category.c (SET_CATEGORY_SET, set_category_set): Move here.
11971 * category.h: ... from here.
11972 * category.c (check_category_table, set_category_set): Now static.
11974 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
11975 * lisp.h: Remove these decls.
11977 * buffer.c (buffer_count): Remove unused var.
11979 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
11980 so that it's not optimized away.
11981 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
11982 * dispextern.h (bidi_dump_cached_states): Remove, since it's
11983 exported only to the debugger.
11985 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
11986 * atimer.h (run_all_atimers): Remove; not exported.
11988 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
11989 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
11990 was inaccessible from Lisp.
11991 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
11992 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
11994 alloc.c: Import and export fewer symbols, and remove unused items.
11995 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
11996 is defined.
11997 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
11998 it's not optimized away by whole-program optimization.
11999 (message_enable_multibyte, free_misc): Remove.
12000 (catchlist, handlerlist, mark_backtrace):
12001 Declare only if BYTE_MARK_STACK.
12002 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
12003 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
12004 (message_enable_multibyte): Remove decl.
12005 (free_misc, interval_free_list, float_block, float_block_index):
12006 (n_float_blocks, float_free_list, cons_block, cons_block_index):
12007 (cons_free_list, last_marked_index):
12008 Now static.
12009 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
12010 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
12011 (mark_backtrace): Define only if BYTE_MARK_STACK.
12012 * xdisp.c (message_enable_multibyte): Now static.
12014 Declare Lisp_Object Q* variables to be 'static' if not exported.
12015 This makes it easier for human readers (and static analyzers)
12016 to see whether these variables are used from other modules.
12017 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
12018 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
12019 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
12020 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:
12021 * lread.c, macros.c, minibuf.c, print.c, process.c, search.c:
12022 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
12023 * xmenu.c, xselect.c:
12024 Declare Q* vars static if they are not used in other modules.
12025 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
12026 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
12027 Remove decls of unexported vars.
12028 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
12030 * lisp.h (DEFINE_FUNC): Make sname 'static'.
12032 Make Emacs functions such as Fatom 'static' by default.
12033 This makes it easier for human readers (and static analyzers)
12034 to see whether these functions can be called from other modules.
12035 DEFUN now defines a static function. To make the function external
12036 so that it can be used in other C modules, use the new macro DEFUE.
12037 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
12038 (Finit_image_library):
12039 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
12040 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
12041 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
12042 Remove decls, since these functions are now static.
12043 (Funintern, Fget_internal_run_time): New decls, since these functions
12044 were already external.
12046 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
12047 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
12048 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
12049 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
12050 * keyboard.c, keymap.c, lread.c:
12051 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
12052 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
12053 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
12054 Mark functions with DEFUE instead of DEFUN,
12055 if they are used in other modules.
12056 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
12057 decls for now-static functions.
12058 * buffer.h (Fdelete_overlay): Remove decl.
12059 * callproc.c (Fgetenv_internal): Mark as internal.
12060 * composite.c (Fremove_list_of_text_properties): Remove decl.
12061 (Fcomposition_get_gstring): New forward static decl.

12064 * doc.c (Fdocumntation_property): New forward static decl.
12065 * eval.c (Ffetch_bytecode): New forward static decl.
12066 (Funintern): Remove extern decl; now in .h file where it belongs.
12067 * fileio.c (Fmake_symbolic_link): New forward static decl.
12068 * image.c (Finit_image_library): New forward static decl.
12069 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
12070 * intervals.h (Fprevious_property_change):
12071 (Fremove_list_of_text_properties): Remove decls.
12072 * keyboard.c (Fthis_command_keys): Remove decl.
12073 (Fcommand_execute): New forward static decl.
12074 * keymap.c (Flookup_key): New forward static decl.
12075 (Fcopy_keymap): Now static.
12076 * keymap.h (Flookup_key): Remove decl.
12077 * process.c (Fget_process): New forward static decl.
12078 (Fprocess_datagram_address): Mark as internal.

12080 (skip_chars): Remove duplicate decl.
12081 * textprop.c (Fprevious_property_change): New forward static decl.
12082 * window.c (Fset_window_fringes, Fset_window_scroll_bars):
12083 Now internal.
12084 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
12085 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
12087 * editfns.c (Fformat): Remove unreachable code.
12089 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
12091 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
12092 change. (Bug#8496)
12094 2011-04-13 Eli Zaretskii <eliz@gnu.org>
12096 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
12097 when at ZV. (Bug#8487)
12099 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
12101 * charset.c (Fclear_charset_maps): Use xfree instead of free.
12102 (Bug#8437)
12103 * keyboard.c (parse_tool_bar_item): Likewise.
12104 * sound.c (sound_cleanup, alsa_close): Likewise.
12105 * termcap.c (tgetent): Likewise.
12106 * xfns.c (x_default_font_parameter): Likewise.
12107 * xsettings.c (read_and_apply_settings): Likewise.
12109 * alloc.c (overrun_check_malloc, overrun_check_realloc)
12110 (overrun_check_free): Protoize.
12112 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
12114 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
12115 since callers should never pass a negative size.
12116 Change the signature to match that of plain 'read' and 'write'; see
12117 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
12118 * lisp.h: Update prototypes of emacs_write and emacs_read.
12120 2011-04-11 Eli Zaretskii <eliz@gnu.org>
12122 * xdisp.c (redisplay_window): Don't try to determine the character
12123 position of the scroll margin if the window start point w->startp
12124 is outside the buffer's accessible region. (Bug#8468)
12126 2011-04-10 Eli Zaretskii <eliz@gnu.org>
12128 Fix write-region and its subroutines for buffers > 2GB.
12129 * fileio.c (a_write, e_write): Modify declaration of arguments and
12130 local variables to support buffers larger than 2GB.
12131 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
12133 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
12134 argument, local variables, and return value.
12136 * lisp.h: Update prototypes of emacs_write and emacs_read.
12138 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
12140 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
12142 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
12144 Fix more problems found by GCC 4.6.0's static checks.
12146 * xdisp.c (vmessage): Use a better test for character truncation.
12148 * charset.c (load_charset_map): <, not <=, for optimization,
12149 and to avoid potential problems with integer overflow.
12150 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
12151 * casetab.c (set_identity, shuffle): Likewise.
12152 * editfns.c (Fformat): Likewise.
12153 * syntax.c (skip_chars): Likewise.
12155 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
12156 This also lets GCC 4.6.0 generate slightly better loop code.
12158 * callint.c (Fcall_interactively): <, not <=, for optimization.
12159 (Fcall_interactively): Count the number of arguments produced,
12160 not the number of arguments given. This is simpler and lets GCC
12161 4.6.0 generate slightly better code.
12163 * ftfont.c: Distingish more carefully between FcChar8 and char.
12164 The previous code passed unsigned char * to a functions like
12165 strlen and xstrcasecmp that expect char *, which does not
12166 conform to the C standard.
12167 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
12168 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
12169 char * when the C standard requires it.
12171 * keyboard.c (read_char): Remove unused var.
12173 * eval.c: Port to Windows vsnprintf (Bug#8435).
12174 Include <limits.h>.
12175 (SIZE_MAX): Define if the headers do not.
12176 (verror): Do not give up if vsnprintf returns a negative count.
12177 Instead, grow the buffer. This ports to Windows vsnprintf, which
12178 does not conform to C99. Problem reported by Eli Zaretskii.
12179 Also, simplify the allocation scheme, by avoiding the need for
12180 calling realloc, and removing the ALLOCATED variable.
12182 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
12184 Remove invocations of doprnt, as Emacs now uses vsnprintf.
12185 But keep the doprint source code for now, as we might revamp it
12186 and use it again (Bug#8435).
12187 * lisp.h (doprnt): Remove.
12188 * Makefile.in (base_obj): Remove doprnt.o.
12189 * deps.mk (doprnt.o): Remove.
12191 error: Print 32- and 64-bit integers portably (Bug#8435).
12192 Without this change, on typical 64-bit hosts error ("...%d...", N)
12193 was used to print both 32- and 64-bit integers N, which relied on
12194 undefined behavior.
12195 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
12196 * lisp.h (error, verror): Mark as printf-like functions.
12197 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
12198 Report overflow in size calculations when allocating printf buffer.
12199 Do not truncate output string at its first null byte.
12200 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
12201 Truncate the output at a character boundary, since vsnprintf does not
12202 do that.
12203 * charset.c (check_iso_charset_parameter): Convert internal
12204 character to string before calling 'error', since %c now has the
12205 printf meaning.
12206 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
12207 overflow when computing char to be passed to 'error'. Do not
12208 pass Lisp_Object to 'error'; pass the integer instead.
12209 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
12210 formatted with plain %d.
12212 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
12214 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
12216 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
12218 * xterm.c (x_catch_errors): Remove duplicate declaration.
12220 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
12222 * xdisp.c, lisp.h (message_nolog): Remove; unused.
12224 2011-04-10 Jim Meyering <meyering@redhat.com>
12226 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
12227 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
12228 return ssize_t not "int", and use size_t as the buffer length.
12229 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
12230 * gnutls.h: Update declarations.
12231 * process.c (read_process_output): Use ssize_t, to match.
12232 (send_process): Likewise.
12234 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12236 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
12238 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12240 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
12241 Use unsigned char, to match FcChar8 type definition.
12243 * xterm.c (handle_one_xevent):
12244 * xmenu.c (create_and_show_popup_menu):
12245 * xselect.c (x_decline_selection_request)
12246 (x_reply_selection_request): Avoid type-punned deref of X events.
12248 2011-04-09 Eli Zaretskii <eliz@gnu.org>
12250 Fix some uses of `int' instead of EMACS_INT.
12251 * search.c (string_match_1, fast_string_match)
12252 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
12253 (scan_buffer, find_next_newline_no_quit)
12254 (find_before_next_newline, search_command, Freplace_match)
12255 (Fmatch_data): Make some `int' variables be EMACS_INT.
12257 * xdisp.c (display_count_lines): 3rd argument and return value now
12258 EMACS_INT. All callers changed.
12259 (pint2hrstr): Last argument is now EMACS_INT.
12261 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
12262 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
12263 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
12264 (decode_coding_utf_16, decode_coding_emacs_mule)
12265 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
12266 (decode_coding_ccl, decode_coding_charset)
12267 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
12268 (decode_coding_iso_2022, decode_coding_emacs_mule)
12269 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
12270 <char_offset, last_offset>: Declare EMACS_INT.
12271 (encode_coding_utf_8, encode_coding_utf_16)
12272 (encode_coding_emacs_mule, encode_invocation_designation)
12273 (encode_designation_at_bol, encode_coding_iso_2022)
12274 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
12275 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
12276 Declare EMACS_INT.
12277 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
12278 (encode_invocation_designation): Last argument P_NCHARS is now
12279 EMACS_INT.
12280 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
12281 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
12283 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
12284 All users changed.
12286 * ccl.c (Fccl_execute_on_string): Declare some variables
12287 EMACS_INT.
12289 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
12291 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
12293 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
12295 * process.c (Fformat_network_address): Doc fix.
12297 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
12299 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
12301 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
12303 * keyboard.c (read_char): Call Lisp function help-form-show,
12304 instead of using internal_with_output_to_temp_buffer.
12305 (Qhelp_form_show): New var.
12306 (syms_of_keyboard): Use DEFSYM macro.
12308 * print.c (internal_with_output_to_temp_buffer): Function deleted.
12310 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
12312 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
12314 * process.c (Flist_processes): Remove to Lisp.
12315 (list_processes_1): Delete.
12317 2011-04-06 Eli Zaretskii <eliz@gnu.org>
12319 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
12321 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
12323 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
12325 Fix more problems found by GCC 4.6.0's static checks.
12327 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
12329 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
12331 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
12333 * xdisp.c (vmessage): Mark as a printf-like function.
12335 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
12337 * sound.c (sound_warning): Don't crash if arg contains a printf format.
12339 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
12340 printf-like functions.
12341 (tiff_load): Add casts to remove these marks before passing them
12342 to system-supplied API.
12344 * eval.c (Fsignal): Remove excess argument to 'fatal'.
12346 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
12347 This avoids several warnings with gcc -Wstrict-overflow.
12348 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
12349 directly, rather than having caller test rule sign. This avoids
12350 some unnecessary tests.
12351 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
12352 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
12353 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
12355 * xfont.c (xfont_text_extents): Remove var that was set but not used.
12356 (xfont_open): Avoid unnecessary tests.
12358 * composite.c (composition_gstring_put_cache): Use unsigned integer.

12365 (COMPOSITION_DECODE_RULE): Use it.
12366 * composite.c (get_composition_id): Remove unused local vars,
12367 by using the new macro.
12369 * textprop.c (set_text_properties_1): Change while to do-while,
12370 since the condition is always true at first.
12372 * intervals.c (graft_intervals_into_buffer): Mark var as used.
12373 (interval_deletion_adjustment): Return unsigned value.
12374 All uses changed.
12376 * process.c (list_processes_1, create_pty, read_process_output):
12377 (exec_sentinel): Remove vars that were set but not used.
12378 (create_pty): Remove unnecessary "volatile"s.

12389 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
12390 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
12392 * print.c (print_error_message): Avoid int overflow.
12394 * font.c (font_list_entities): Redo for clarity,
12395 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.

12410 (wordify): Omit three unnecessary tests.
12412 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

12417 * dired.c (file_name_completion): Remove var that is set but not used.
12419 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
12421 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
12422 (Finsert_file_contents): Remove unnecessary code checking fd.

12428 but not used.
12430 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
12431 Remove vars that are set but not used.
12432 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
12433 (timer_check_2): Mark vars as initialized.
12435 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
12437 * image.c (lookup_image): Remove var that is set but not used.
12438 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
12440 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
12441 that are set but not used.
12443 * xfns.c (make_invisible_cursor): Don't return garbage
12444 if XCreateBitmapFromData fails (Bug#8410).
12446 * xselect.c (x_get_local_selection, x_handle_property_notify):
12447 Remove vars that are set but not used.
12449 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
12450 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
12452 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
12453 Remove var that is set but not used.
12454 (scroll_bar_windows_size): Now size_t, not int.
12455 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
12456 Check for overflow.
12458 * xfaces.c (realize_named_face): Remove vars that are set but not used.
12459 (map_tty_color) [!defined MSDOS]: Likewise.
12461 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
12463 * coding.c: Remove vars that are set but not used.
12464 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
12465 All callers changed.
12466 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
12467 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
12468 (decode_coding_charset): Remove vars that are set but not used.
12470 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
12471 that is set but not used.
12473 * print.c (print_object): Remove var that is set but not used.
12475 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
12476 The gnulib version avoids calling malloc in the usual case,
12477 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
12478 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
12479 * filelock.c (current_lock_owner): Likewise.
12480 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
12481 * sysdep.c: Include allocator.h, careadlinkat.h.
12482 (emacs_no_realloc_allocator): New static constant.
12483 (emacs_readlink): New function.
12484 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
12485 ../lib/careadlinkat.h.
12487 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
12489 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
12490 first non-nil return value).
12492 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
12494 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6

12512 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
12513 (ns_get_family): Likewise.
12515 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
12517 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
12519 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
12521 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
12522 later (Bug#8403).
12524 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
12526 Add lexical binding.
12528 * window.c (Ftemp_output_buffer_show): New fun.
12529 (Fsave_window_excursion):
12530 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
12532 * lread.c (lisp_file_lexically_bound_p): New function.
12533 (Fload): Bind Qlexical_binding.
12534 (readevalloop): Remove `evalfun' arg.
12535 Bind Qinternal_interpreter_environment.
12536 (Feval_buffer): Bind Qlexical_binding.
12537 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
12538 Mark as dynamic.
12539 (syms_of_lread): Declare `lexical-binding'.
12541 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
12543 * keyboard.c (eval_dyn): New fun.
12544 (menu_item_eval_property): Use it.
12546 * image.c (parse_image_spec): Use Ffunctionp.
12548 * fns.c (concat, mapcar1): Accept byte-code-functions.
12550 * eval.c (Fsetq): Handle lexical vars.
12551 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
12552 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
12553 (FletX, Flet): Obey lexical binding.
12554 (Fcommandp): Handle closures.
12555 (Feval): New `lexical' arg.
12556 (eval_sub): New function extracted from Feval. Use it almost
12557 everywhere where Feval was used. Look up vars in lexical env.
12558 Handle closures.
12559 (Ffunctionp): Move from subr.el.
12560 (Ffuncall): Handle closures.
12561 (apply_lambda): Remove `eval_flags'.
12562 (funcall_lambda): Handle closures and new byte-code-functions.
12563 (Fspecial_variable_p): New function.
12564 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
12565 but without exporting it to Lisp.
12567 * doc.c (Fdocumentation, store_function_docstring):
12568 * data.c (Finteractive_form): Handle closures.
12570 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
12571 interactive spec.
12573 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
12574 New byte-codes.
12575 (exec_byte_code): New function extracted from Fbyte_code to handle new
12576 calling convention for byte-code-functions. Add new byte-codes.
12578 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
12580 * alloc.c (Fmake_symbol): Init new `declared_special' field.
12582 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
12584 * xdisp.c (redisplay_internal): Fix prototype.
12586 2011-03-31 Eli Zaretskii <eliz@gnu.org>
12588 * xdisp.c (SCROLL_LIMIT): New macro.
12589 (try_scrolling): Use it when setting scroll_limit.
12590 Limit scrolling to 100 screen lines.
12591 (redisplay_window): Even when falling back on "recentering",
12592 position point in the window according to scroll-conservatively,
12593 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
12595 (try_scrolling): When point is above the window, allow searching
12596 as far as scroll_max, or one screenful, to compute vertical
12597 distance from PT to the scroll margin position. This prevents
12598 try_scrolling from unnecessarily failing when
12599 scroll-conservatively is set to a value slightly larger than the
12600 window height. Clean up the case of PT below the margin at bottom
12601 of window: scroll_max can no longer be INT_MAX. When aggressive
12602 scrolling is in use, don't let point enter the opposite scroll
12603 margin as result of the scroll.
12604 (syms_of_xdisp) <scroll-conservatively>: Document the
12605 threshold of 100 lines for never-recentering scrolling.
12607 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
12609 * dispextern.h (move_it_by_lines):
12610 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

12612 (message_log_check_duplicate): Remove parameters `prev_bol' and
12613 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
12614 (redisplay_internal): Remove parameter `preserve_echo_area',
12615 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
12617 * indent.c (Fvertical_motion):
12618 * window.c (window_scroll_pixel_based, Frecenter):
12619 Don't pass `need_y_p' to `move_it_by_lines'.
12621 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
12623 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
12624 steal a few bits to be more compact.

12626 Remove unneeded casts.
12628 * bytecode.c (Fbyte_code): CAR and CDR can GC.
12630 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
12632 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
12633 binding" message (bug#7967).
12635 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
12637 Fix more problems found by GCC 4.6.0's static checks.
12639 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
12640 Remove unused local var.
12642 * editfns.c (Fmessage_box): Remove unused local var.
12644 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
12645 (note_mode_line_or_margin_highlight, note_mouse_highlight):
12646 Omit unused local vars.
12647 * window.c (shrink_windows): Omit unused local var.
12648 * menu.c (digest_single_submenu): Omit unused local var.
12649 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
12650 Omit unused local var.
12652 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
12653 Don't assume string length fits in int.
12654 (keyremap_step, read_key_sequence): Use size_t for sizes.

12658 instead of alloca (Bug#8344).
12660 * eval.c (Fbacktrace): Don't assume nargs fits in int.
12661 (Fbacktrace_frame): Don't assume nframes fits in int.
12663 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
12665 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
12666 concerns.
12668 * term.c (produce_glyphless_glyph): Remove unnecessary test.
12670 * cm.c (calccost): Turn while-do into do-while, for clarity.
12672 * keyboard.c (syms_of_keyboard): Use the same style as later
12673 in this function when indexing through an array. This also
12674 works around GCC bug 48267.
12676 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
12678 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
12680 * chartab.c (sub_char_table_ref_and_range): Redo for slight
12681 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
12683 * keyboard.c, keyboard.h (num_input_events): Now size_t.
12684 This avoids undefined behavior on integer overflow, and is a bit
12685 more convenient anyway since it is compared to a size_t variable.
12687 Variadic C functions now count arguments with size_t, not int.
12688 This avoids an unnecessary limitation on 64-bit machines, which
12689 caused (substring ...) to crash on large vectors (Bug#8344).

12699 * fns.c (concat): Likewise.
12700 * frame.c (x_set_frame_parameters): Likewise.
12701 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
12702 0 if not found, not -1. All callers changed.
12704 * alloc.c (garbage_collect): Don't assume stack size fits in int.
12705 (stack_copy_size): Now size_t, not int.
12706 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
12708 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
12710 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
12711 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

12727 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
12728 don't set the hook to nil, but remove the offending function instead.
12729 (Qcommand_hook_internal): Remove, unused.
12730 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
12731 Vcommand_hook_internal.

12734 (funcall_nil, funcall_not): New functions.
12735 (run_hook_with_args): Call each function through a `funcall' argument.

12752 * w32.c (_wsa_errlist): Use braces for struct initializers.
12754 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

12807 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
12809 * keyboard.c (timer_check): Remove parameter `do_it_now',
12810 unused since 1996-04-12T06:01:29Z!rms@gnu.org.

12901 * term.c (Fsuspend_tty, Fresume_tty):
12902 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
12903 * window.c (temp_output_buffer_show):
12904 * insdel.c (signal_before_change):
12905 * frame.c (Fhandle_switch_frame):
12906 * fileio.c (Fdo_auto_save):

12911 * buffer.c (Fkill_all_local_variables):
12912 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
12913 Use Frun_hooks.
12914 (command_loop_1): Use Frun_hooks. Call safe_run_hooks

12917 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
12919 Fix more problems found by GCC 4.5.2's static checks.
12921 * coding.c (encode_coding_raw_text): Avoid unnecessary test
12922 the first time through the loop, since we know p0 < p1 then.
12923 This also avoids a gcc -Wstrict-overflow warning.
12925 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
12926 leading to a memory leak, possible in functions like
12927 load_charset_map_from_file that can allocate an unbounded number
12928 of objects (Bug#8318).
12930 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
12931 that could (at least in theory) be that large.
12933 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
12934 This is less likely to overflow, and avoids undefined behavior if
12935 overflow does occur. All callers changed. Use strtoul to scan
12936 for the unsigned long integer.
12937 (pint2hrstr): Simplify and tune code slightly.
12938 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

12951 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
12953 * process.c (Fmake_network_process): Use socklen_t, not int,
12954 where POSIX says socklen_t is required in portable programs.
12955 This fixes a porting bug on hosts like 64-bit HP-UX, where
12956 socklen_t is wider than int (Bug#8277).
12957 (Fmake_network_process, server_accept_connection):
12958 (wait_reading_process_output, read_process_output):
12959 Likewise.

12971 Make tparam.h and terminfo.c consistent.
12972 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
12973 Include tparam.h instead, since it declares them.
12974 * cm.h (PC): Remove extern decl; tparam.h now does this.
12975 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
12976 * terminfo.c: Include tparam.h, to check interfaces.
12977 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
12978 (tparam): Adjust signature to match interface in tparam.h;
12979 this removes some undefined behavior. Check that outstring and len
12980 are zero, which they always are with Emacs.
12981 * tparam.h (PC, BC, UP): New extern decls.
12983 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
12984 (xftfont_open): Rename locals to avoid shadowing.

12996 * xml.c (make_dom): Now static.
12998 * composite.c (composition_compute_stop_pos): Rename local to
12999 avoid shadowing.
13000 (composition_reseat_it): Remove unused locals.
13001 (find_automatic_composition, composition_adjust_point): Likewise.
13002 (composition_update_it): Mark var as initialized.

13008 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
13009 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
13010 (BUF_DEC_POS): Be more systematic about renaming local temporaries
13011 to avoid shadowing.
13013 * textprop.c (property_change_between_p): Remove; unused.

13022 * sound.c (wav_play, au_play, Fplay_sound_internal):
13023 Fix pointer signedness.
13024 (alsa_choose_format): Remove unused local var.
13025 (wav_play): Initialize a variable to 0, to prevent undefined
13026 behavior (Bug#8278).
13028 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
13030 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
13032 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
13033 clobbering (Bug#8298).
13034 * sysdep.c (sys_subshell): Likewise.
13035 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
13037 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
13038 This should get cleaned up, so that child_setup has the
13039 same signature on all platforms.
13041 * callproc.c (call_process_cleanup): Now static.
13042 (relocate_fd): Rename locals to avoid shadowing.
13044 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
13046 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
13047 not to be necessary, and produces flickering.
13049 2011-03-20 Glenn Morris <rgm@gnu.org>
13051 * config.in: Remove file.
13053 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

13098 Define only if needed.
13100 * unexelf.c (unexec): Name an expression,
13101 to avoid gcc -Wbad-function-cast warning.
13102 Use a different way to cause a compilation error if anyone uses
13103 n rather than nn, a way that does not involve shadowing.
13104 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
13106 * deps.mk (unexalpha.o): Remove; unused.
13108 New file unexec.h, the (simple) interface for unexec (Bug#8267).

13197 they're used.
13198 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if

13261 New macros, so that the caller can use some names other than
13262 gcpro1, gcpro2, etc.
13263 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
13264 of the new macros.
13265 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
13266 argument, for consistency with GCPRO2_VAR, etc: it is now the
13267 prefix of the variable, not the variable itself. All uses
13268 changed.
13269 * dired.c (directory_files_internal, file_name_completion):
13270 Rename locals to avoid shadowing.
13272 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
13273 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
13274 dired.c's scmp function, had undefined behavior.
13275 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13276 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
13277 * buffer.h: ... to here, because these macros use current_buffer,
13278 and the new implementation with inline functions needs to have
13279 current_buffer in scope now, rather than later when the macros
13280 are used.
13281 (downcase, upcase1): New static inline functions.
13282 (DOWNCASE, UPCASE1): Reimplement using these functions.
13283 This avoids undefined behavior in expressions like
13284 DOWNCASE (x) == DOWNCASE (y), which previously suffered
13285 from race conditions in accessing the global variables
13286 case_temp1 and case_temp2.
13287 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
13288 * lisp.h (case_temp1, case_temp2): Remove their decls.

13297 Now static.
13298 (file_name_as_directory): Use const pointers when appropriate.
13299 (Fexpand_file_name): Likewise. In particular, newdir might

13302 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
13303 signedness issues.

13309 to avoid shadowing.
13311 * marker.c (bytepos_to_charpos): Remove; unused.
13313 * lisp.h (verify_bytepos, count_markers): New decls,
13314 so that gcc does not warn that these functions aren't declared.
13316 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
13317 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
13318 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
13319 (copy_text): Remove unused local var.

13322 (lock_file_1): Rename local to avoid shadowing.
13324 * buffer.c (fix_overlays_before): Mark locals as initialized.
13325 (fix_start_end_in_overlays): Likewise. This function should be
13326 simplified by using pointers-to-pointers, but that's a different
13327 matter.
13328 (switch_to_buffer_1): Now static.
13329 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
13330 (report_overlay_modification): Rename locals to avoid shadowing.
13332 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
13333 Fix pointer signedness issue.
13334 (sys_subshell): Mark local as volatile if checking for lint,
13335 to suppress a gcc -Wclobbered warning that does not seem to be right.
13336 (MAXPATHLEN): Define only if needed.
13338 * process.c (serial_open, serial_configure): Move decls from here ...
13339 * systty.h: ... to here, so that they can be checked.
13341 * fns.c (get_random, seed_random): Move extern decls from here ...
13342 * lisp.h: ... to here, so that they can be checked.
13344 * sysdep.c (reset_io): Now static.
13345 (wait_for_termination_signal): Remove; unused.
13347 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
13348 (copy_keymap_item, append_key, push_text_char_description):
13349 Now static.
13350 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
13351 (DENSE_TABLE_SIZE): Remove; unused.
13352 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
13353 (describe_map_tree):
13354 Rename locals to avoid shadowing.
13356 * keyboard.c: Declare functions static if they are not used elsewhere.
13357 (echo_char, echo_dash, cmd_error, top_level_2):
13358 (poll_for_input, handle_async_input): Now static.
13359 (read_char, kbd_buffer_get_event, make_lispy_position):

13373 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
13374 (DEFINE_DUMMY_FUNCTION): New macro.
13375 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
13376 Use it.
13377 (main): Add casts to avoid warnings
13378 if GCC considers string literals to be constants.
13380 * lisp.h (fatal_error_signal): Add decl, since it's exported.
13382 * dbusbind.c: Pointer signedness fixes.
13383 (xd_signature, xd_append_arg, xd_initialize):
13384 (Fdbus_call_method, Fdbus_call_method_asynchronously):
13385 (Fdbus_method_return_internal, Fdbus_method_error_internal):
13386 (Fdbus_send_signal, xd_read_message_1, Fdbus_register_service):

13683 for clarity, and to avoid gcc -Wempty-body warning.
13684 (Fdefine_coding_system_internal): Don't redeclare 'i' inside
13685 a block, when the outer 'i' will do.
13686 (decode_coding_utf_8, decode_coding_utf_16, detect_coding_emacs_mule):
13687 (emacs_mule_char, decode_coding_emacs_mule, detect_coding_iso_2022):
13688 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5):
13689 (decode_coding_raw_text, decode_coding_charset, get_translation_table):
13690 (Fdecode_sjis_char, Fdefine_coding_system_internal):
13691 Rename locals to avoid shadowing.
13692 * character.h (FETCH_STRING_CHAR_ADVANCE): Likewise.
13693 * coding.c (emacs_mule_char, encode_invocation_designation):

13696 (decode_coding_object, encode_coding_object, detect_coding_system):
13697 (decode_coding_emacs_mule): Mark variables that gcc
13698 -Wuninitialized does not deduce are never used uninitialized.
13699 (detect_coding_iso_2022): Initialize a local variable that might
13700 be used uninitialized. Leave a FIXME because it's not clear that
13701 this initialization is needed. (Bug#8211)
13702 (ISO_CODE_LF, ISO_CODE_CR, CODING_ISO_FLAG_EUC_TW_SHIFT):
13703 (ONE_MORE_BYTE_NO_CHECK, UTF_BOM, UTF_16_INVALID_P):

13734 Move these decls to tparam.h, and make them agree with what
13735 is actually in tparam.c. The previous trick of using incompatible
13736 decls in different modules does not conform to the C standard.
13737 All callers of tparam changed to use tparam's actual API.
13738 * tparam.c (tparam1, tparam, tgoto):
13739 Use const pointers where appropriate.
