377 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
378 * nsterm.m (ns_term_init):
379 Avoid the need for strncpy, by using build_string or
380 make_unibyte_string directly. Use dtoastr, not snprintf.

446 Move PENDING_OUTPUT_COUNT definition to configure.
448 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
449 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
450 * s/gnu.h (DATA_START): Move definitions to configure.
452 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
453 We include usg5-4-common.h, which defines them both.
455 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
456 O_RDONLY already includes it).
458 Stop ns builds setting the EMACSLOADPATH environment variable.
459 * nsterm.m (ns_load_path): Rename from ns_init_paths.
460 Now it does not set EMACSLOADPATH, just returns the load-path string.
461 * nsterm.h: Update accordingly.
462 * lread.c [HAVE_NS]: Include nsterm.h.
463 (init_lread) [HAVE_NS]: Use ns_load_path.
464 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
466 2012-07-09 Glenn Morris <rgm@gnu.org>
468 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
469 since the included bsd-common.h does so.
471 Stop ns builds setting the EMACSPATH environment variable.
472 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
473 (ns_init_paths): Do not set EMACSPATH.
474 * nsterm.h (ns_exec_path): Add it.
475 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
476 Use ns_exec_path.
478 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
480 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
482 * process.c (wait_reading_process_output): 'waitchannels' was unset
483 when read_kbd || !NILP (wait_for_cell); fix this.
485 Add GCC-style 'const' attribute to functions that can use it.
486 * character.h (char_resolve_modifier_mask):
487 * keyboard.h (make_ctrl_char):
488 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
489 (init_character_once, next_almost_prime, init_fns, init_image)
490 (flush_pending_output, init_sound):
491 * mem-limits.h (start_of_data):

494 * emacs.c (DEFINE_DUMMY_FUNCTION):
495 Declare the dummy function with ATTRIBUTE_CONST.
496 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
497 Add decls with ATTRIBUTE_CONST.
499 Minor improvements to make_formatted_string.
500 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
501 where int is good enough, as vsprintf returns an int.
502 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
504 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
506 Use make_formatted_string to avoid double length calculation.
507 * lisp.h (make_formatted_string): New prototype.
508 * alloc.c (make_formatted_string): New function.
509 * buffer.c (Fgenerate_new_buffer_name): Use it.
510 * dbus.c (syms_of_dbusbind): Likewise.
511 * editfns.c (Fcurrent_time_zone): Likewise.
512 * filelock.c (get_boot_time): Likewise.
513 * frame.c (make_terminal_frame, set_term_frame_name)
514 (x_report_frame_params): Likewise.
515 * image.c (gs_load): Likewise.

522 2012-07-09 Glenn Morris <rgm@gnu.org>
524 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
525 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
526 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.

529 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
531 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
533 Move marker debugging code under MARKER_DEBUG.
534 * marker.c (MARKER_DEBUG): Move marker debugging code under
535 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
536 for bootstrap with --enable-checking (~3x slowdown reported
537 by Juanma Barranquero <lekktu@gmail.com>).
538 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
540 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
542 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
543 See <http://bugs.gnu.org/11825#29>.
545 2012-07-08 Eli Zaretskii <eliz@gnu.org>
547 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
548 has no font, use the frame's font. (Bug#11813)
549 (display_line): Add commentary about displaying truncation glyphs
550 on GUI frames.
551 (produce_special_glyphs): Move here from term.c.
553 * term.c (produce_special_glyphs): Move to xdisp.c.
555 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
556 section.
558 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
560 * xdisp.c (display_line): Avoid warning about implicit declaration
561 of FRAME_FONT.
563 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
565 * lisp.h: Remove empty conditional.
567 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
569 * lread.c (load_path_check): Now static.
571 Fix some minor --with-ns problems found by static checking.
572 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
573 (x_set_font) [!HAVE_X_WINDOWS]:
574 * image.c (xpm_load_image) [HAVE_NS]:
575 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
576 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
577 Remove unused local.
578 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
579 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
580 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
581 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
582 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
583 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
584 Fix pointer signedness problem.
585 * xfaces.c (FRAME_X_FONT_TABLE):
586 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
588 2012-07-07 Glenn Morris <rgm@gnu.org>
590 * lread.c (load_path_check): New function, split from init_lread.
591 (init_lread): Reorganize. Motivation:
592 If EMACSLOADPATH is set, check/warn about that rather than the
593 defaults, which we are not going to use. Hence we can remove
594 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
595 Don't warn if site-lisp directories are missing.
596 If not installed, start from a blank load-path, since
597 PATH_LOADSEARCH refers to the eventual installation directories.
599 2012-07-07 Eli Zaretskii <eliz@gnu.org>
601 Support truncation and continuation glyphs on GUI frames, when
602 fringes are disabled. (Bug#11832)
603 * xdisp.c (init_iterator): Get dimensions of truncation and
604 continuation glyphs even if on GUI frames. Adjust
605 it->last_visible_x on GUI frames when the left or right fringes,
606 or both, are absent.
607 (start_display, move_it_in_display_line_to): Handle the case of a
608 GUI frame without a fringe to display continuation or truncation
609 glyphs.
610 (insert_left_trunc_glyphs): Support GUI frames: make sure
611 truncation glyphs overwrite enough glyphs from the current line to
612 have sufficient space in pixels.
613 (display_line): Support truncation and continuation glyphs on GUI
614 frames. If some spare pixels are left on the line after inserting
615 the truncation glyphs, fill that space with a stretch glyph of a
616 suitably computed width.
618 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
619 produce_glyphs, to support GUI sessions.
621 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
623 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
625 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
627 Do not require float-time's arg to fit in time_t (Bug#11825).
628 This works better on hosts where time_t is unsigned, and where
629 float-time is applied to the (negative) difference between two times.
630 * editfns.c (decode_time_components): Last arg is now double *,
631 not int *, and means to store all the result as a double, without
632 worrying about whether the seconds part fits in time_t.
633 All callers changed.
634 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
635 All callers changed.
636 (Ffloat_time): Do not fail merely because the specified time falls
637 outside of time_t range.
639 2012-07-07 Glenn Morris <rgm@gnu.org>
641 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

648 Update dependencies.
650 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
652 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
654 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
655 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
656 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
657 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
658 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
659 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
661 * xfont.c (compare_font_names): Redo to omit the need for casts.
663 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
665 * xfns.c (Fx_change_window_property): Doc fix.
666 * w32fns.c (Fx_change_window_property): Doc fix.
668 * w32fns.c (Fx_window_property): Accept the same arguments as the
669 X Windows version. Doc fix.
670 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
672 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
673 Eli Zaretskii <eliz@gnu.org>
675 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
676 Windows-specific code from nt/config.nt moved here.
677 Obsolete settings removed.
679 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
681 * process.c: Avoid unnecessary calls to gettime.
682 (wait_reading_process_output): Don't get the time of day
683 when gobbling data immediately and not waiting, as there's no need
684 for it in that case. This removes a FIXME.
686 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
688 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
689 is defined (Bug#11768).
691 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
693 Fix marker debugging code.
694 * marker.c (byte_char_debug_check): Do not perform the check
695 if buffer is not multibyte.
696 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
697 Call byte_char_debug_check with correct arguments.
699 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
701 Compile marker debugging code only if ENABLE_CHECKING is defined.
702 * marker.c (byte_char_debug_check, count_markers):
703 Use only if ENABLE_CHECKING is defined.
704 (byte_debug_flag): Remove.
705 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
706 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
708 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
710 Avoid code repetition in marker-related functions.
711 * marker.c (attach_marker): New function.
712 (Fset_marker, set_marker_restricted, set_marker_both)
713 (set_marker_restricted_both): Use it.
714 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
715 Consistently rename charno to charpos.
716 (marker_position): Add eassert.
717 (marker_byte_position): Convert to eassert.
719 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
721 Simplify list operations in unchain_overlay and unchain_marker.
722 * buffer.c (unchain_overlay): Simplify. Add comment.
723 * marker.c (unchain_marker): Simplify. Fix comments.
725 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
727 Introduce fast path for the widely used marker operation.

733 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
734 (save_restriction_save): Use build_marker.
735 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
736 * window.c (save_window_save): Likewise.
738 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
740 Do not use Fdelete_overlay in delete_all_overlays
741 to avoid redundant calls to unchain_overlay.
742 * buffer.c (drop_overlay): New function.
743 (delete_all_overlays, Fdelete_overlay): Use it.
744 * minibuf.c (get_minibuffer): Fix comment.
746 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
748 Port to OpenBSD 5.1 amd64.
749 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
750 This is needed for OpenBSD, and should be harmless on all BSD systems.
751 Also, include <sys/sysctl.h>, as it should be available on all
752 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
753 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
754 use p_pid member, not kp_proc.pid.
756 2012-07-06 Glenn Morris <rgm@gnu.org>
758 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
760 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
762 More xmalloc and related cleanup.
763 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
764 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
765 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:
766 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
767 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
768 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
769 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
770 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
771 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
772 * xterm.c:
773 Omit needless casts involving void * pointers and allocation.
774 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
775 as the former is more robust if P's type is changed.
776 Prefer xzalloc to xmalloc + memset 0.
777 Simplify malloc-or-realloc to realloc.
778 Don't worry about xmalloc returning a null pointer.
779 Prefer xstrdup to xmalloc + strcpy.
780 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
781 growing it.
782 * keyboard.c (apply_modifiers_uncached): Prefer local array to
783 alloca of a constant.
785 2012-07-05 Eli Zaretskii <eliz@gnu.org>
787 * xdisp.c (display_line): Fix horizontal pixel coordinates when
788 hscroll is larger than the line width. Fixes long and futile
789 looping inside extend_face_to_end_of_line (on a TTY) producing
790 glyphs that are not needed and thrown away.
792 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
794 * marker.c (set_marker_restricted_both): Simplify by using
795 clip_to_bounds.
797 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
799 * editfns.c (region_limit): Simplify by using clip_to_bounds.
801 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>

808 followed by gtk_box_set_homogeneous (Bug#11768).
809 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
810 (update_theme_scrollbar_width, xg_create_scroll_bar):
811 Use gtk_scrollbar_new (Bug#11768).
812 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
813 (is_box_type): New function (Bug#11768).
814 (xg_tool_item_stale_p): Call is_box_type.
815 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
816 with default display (Bug#11768).
818 2012-07-05 Eli Zaretskii <eliz@gnu.org>
820 * xdisp.c (window_hscroll_limited): New function.
821 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
822 coordinates when window's hscroll is set to insanely large
823 values. (Bug#11857)
825 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
827 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
828 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
830 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

886 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
888 * fileio.c (time_error_value): Check the right error number.
889 Problem reported by Troels Nielsen in
890 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
892 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
894 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
895 This should be fixed in a better way; see Eli Zaretskii in
896 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
897 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
899 * fileio.c (time_error_value): Rename from special_mtime.
900 The old name's problems were noted by Eli Zaretskii in
901 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
903 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
904 This variable's comment says Emacs needs at least one GDB-visible
905 symbol of type enum pvec_type, to work around GDB problems.
906 The symbol's value doesn't matter.
908 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
909 that causes compilation to fail on pre-C99 compilers.
911 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
913 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
914 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
916 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

919 headers for buffer_defaults and buffer_local_symbols.
920 Reported by Juanma Barranquero <lekktu@gmail.com>.
922 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
924 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
925 * lisp.h (enum pvec_type): Use fewer bits.
926 (PSEUDOVECTOR_SIZE_BITS): New constant.
927 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
928 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
929 change in pvec_type.
930 (PSEUDOVECTOR_TYPEP): New macro.
931 (TYPED_PSEUDOVECTORP): Use it.

936 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
937 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
938 (sweep_vectors): Use it. Use local var `total_bytes' instead of
939 abusing vector->header.next.nbytes.
940 (live_vector_p): Use PVEC_TYPE.
941 (mark_object): Adapt code to extract pvectype. Use switch.
943 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
945 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
946 Tighten new eassert a bit.
948 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
950 Fix compilation with --enable-gcc-warnings and -O1
951 optimization level.
952 * doprnt.c (doprnt): Change type of tem to int, initialize
953 to avoid compiler warning. Add eassert.
954 * search.c (simple_search): Initialize match_byte to avoid
955 compiler warning. Add eassert.
957 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
959 Avoid weird behavior with large horizontal scrolls.
960 Without this change, for example, large hscroll values would
961 mess up Emacs's display on Fedora 15 x86, presumably due to
962 overflows in int calculations in the display code.
963 Also, if buffers had long lines, Emacs would freeze.
964 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
965 (set_window_hscroll): New function, containing the old guts of
966 Fset_window_hscroll. Return the clipped value.
967 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
968 This avoids the need to check against PTRDIFF_MAX.
970 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
972 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
974 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
976 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
978 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
979 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
980 since GCC 4.4.6 issues a bogus warning for them.
982 Fix bugs in file timestamp newness comparisons.
983 * fileio.c (Ffile_newer_than_file_p):
984 * lread.c (Fload): Use full timestamp resolution of files,
985 not just the 1-second resolution, so that files that are only
986 slightly newer still count as newer.
987 * fileio.c (Ffile_newer_than_file_p): Don't assume file
988 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
990 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
992 * fileio.c: Improve handling of file time marker. (Bug#11852)
993 (special_mtime): New function.
994 (Finsert_file_contents, Fverify_visited_file_modtime):
995 Use it to set special mtime values consistently.
997 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
999 * fileio.c (Finsert_file_contents): Properly handle st_mtime
1000 marker for non-existing file. (Bug#11852)
1002 2012-07-03 Glenn Morris <rgm@gnu.org>
1004 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
1005 and did not make it into globals.h).
1007 2012-07-03 Tom Tromey <tromey@redhat.com>
1009 * window.c (Fset_window_margins, Fset_window_fringes)
1010 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
1011 * textprop.c (Fprevious_property_change): No longer static.
1012 * syntax.c (Fsyntax_table_p): No longer static.
1013 * process.c (Fget_process, Fprocess_datagram_address): No longer
1014 static.
1015 * keymap.c (Flookup_key, Fcopy_keymap): No longer static.
1016 * keyboard.c (Fcommand_execute): No longer static.
1017 Remove EXFUN.
1018 * insdel.c (Fcombine_after_change_execute): No longer static.
1019 * image.c (Finit_image_library): No longer static.

1033 * dispextern.h: Remove EXFUNs.
1034 * intervals.h: Remove EXFUNs.
1035 * fontset.h: Remove EXFUN.
1036 * font.h: Remove EXFUNs.
1037 * dosfns.c (system_process_attributes): Remove EXFUN.
1038 * keymap.h: Remove EXFUNs.
1039 * lisp.h: Remove EXFUNs.
1040 * w32term.h: Remove EXFUNs.
1041 * window.h: Remove EXFUNs.
1042 * xsettings.h: Remove EXFUN.
1043 * xterm.h: Remove EXFUN.
1045 2012-07-03 Glenn Morris <rgm@gnu.org>
1047 * lisp.h (Frandom): Make it visible to C.
1048 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
1049 buffer for invisible buffers. (Bug#1229)
1051 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1053 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
1054 values which aren't power of 2.
1055 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
1056 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
1057 accordingly.
1059 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
1061 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
1063 * alloc.c (mark_object): Revert part of last patch to use `switch'.
1065 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1067 * alloc.c (allocate_vector_block): Remove redundant
1068 calls to mallopt if DOUG_LEA_MALLOC is defined.
1069 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
1070 avoid calls to mallopt if zero_vector is returned.
1072 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1074 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
1075 is enabled, avoid dereferencing NULL current_sblock if
1076 running undumped.
1078 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1080 Cleanup basic buffer management.
1081 * buffer.h (struct buffer): Change layout to use generic vector
1082 marking code. Fix some comments. Change type of 'clip_changed'
1083 to bitfield. Remove unused #ifndef old.
1084 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
1085 (GET_OVERLAYS_AT): Fix indentation.
1086 (for_each_per_buffer_object_at): New macro.
1087 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
1088 (Fbuffer_local_variables): Use it.
1089 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
1090 * alloc.c (allocate_buffer): Adjust to match new layout of
1091 struct buffer. Fix comment.
1092 (mark_overlay): New function.
1093 (mark_buffer): Use it. Use mark_vectorlike to mark normal
1094 Lisp area of struct buffer.
1095 (mark_object): Use it. Adjust marking of misc objects
1096 and related comments.
1098 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
1100 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
1101 wrapper that is not needed because the wrapped code is a no-op (zero
1102 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
1103 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
1105 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
1107 * alloc.c (mark_buffer): Simplify. Remove prototype.
1108 (mark_object): Add comment. Reorganize marking of vector-like
1109 objects. Use CHECK_LIVE for all vector-like objects except buffers
1110 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
1111 redundant calls to mark_vectorlike for bool vectors.
1113 2012-06-30 Glenn Morris <rgm@gnu.org>
1115 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
1117 * epaths.in (PATH_SITELOADSEARCH): New.
1118 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
1119 This is rather than relying on --enable-locallisppath elements
1120 having "site-lisp" in their names. (Bug#10208#25, 11658)
1122 2012-06-30 Eli Zaretskii <eliz@gnu.org>
1124 * w32proc.c (sys_select): Accept and ignore one more argument.
1126 * w32.c (emacs_gnutls_pull): Call select with one more argument.
1128 * sysselect.h [DOS_NT]: Don't include sys/select.h.
1129 (pselect) [!MS_DOS]: Redirect to sys_select.
1131 * sysdep.c: Don't include dos.h and dosfns.h.
1133 * process.c (sys_select):
1134 * msdos.c (sys_select): Accept one more argument and ignore it.
1136 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
1137 adapt data types and code to that.
1139 * dosfns.c:
1140 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
1141 which clashes with the gnulib function of the same name.
1143 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
1145 * font.c (font_style_to_value, font_style_symbolic)
1146 (font_prop_validate_style): Add type checks for values in
1147 font_style_table.
1149 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
1150 argument.
1151 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
1152 uses.
1154 2012-06-29 Eli Zaretskii <eliz@gnu.org>
1156 * xdisp.c (try_window_id): Undo last change.
1158 * w32.c (getwd): Adjust commentary about startup_dir.
1159 (init_environment): Always call sys_access, even in non-MSVC
1160 builds. Don't chdir to the directory of the Emacs executable.
1161 This undoes code from 1997 which was justified by the need to
1162 "avoid conflicts when removing and renaming directories". But its
1163 downside was that every relative file name was being interpreted
1164 relative to the directory of the Emacs executable, which can never
1165 be TRT. In particular, it broke sys_access when called with
1166 relative file names.
1167 (sys_access): Map GetLastError to errno.
1169 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1171 * window.h (struct window): Change type of 'fringes_outside_margins'
1172 to bitfield. Fix comment. Adjust users accordingly.
1173 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
1174 Adjust comment.
1175 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
1176 to ptrdiff_t.
1178 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
1180 * gnutls.c (emacs_gnutls_handshake):
1181 Add QUIT to make the loop interruptible.
1183 2012-06-29 Glenn Morris <rgm@gnu.org>
1185 * charset.c (init_charset): Make lack of etc/charsets fatal.
1187 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1189 * editfns.c (region_limit): Fix type mismatch.
1191 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1193 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
1194 undefined. Convert from xassert to eassert.
1195 * nsmenu.m: Convert from xassert to eassert.
1196 * nsterm.m: Likewise.
1198 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

1202 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
1204 Avoid integer overflow on scroll-left and scroll-right.
1205 * window.c (HSCROLL_MAX): New macro.
1206 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
1207 overflow when requested scroll falls outside ptrdiff_t range.
1209 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
1211 * window.h (struct window): Change type of 'hscroll',
1212 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
1213 'last_modified' and 'last_overlay_modified' to EMACS_INT.
1214 Adjust users accordingly.
1215 * xdisp.c (try_cursor_movement): Replace type check with eassert.
1216 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
1217 from EMACS_INT to ptrdiff_t.
1218 (make_window): Omit redundant initialization.
1220 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
1222 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
1224 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
1226 * window.h (struct window): Change type of 'use_time' and

1235 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
1236 enabled with --enable-checking=[all,glyphs] configure option.
1237 Fix GLYPH_DEBUG usage assuming that it may be undefined,
1238 adjust comments accordingly.
1239 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
1240 undefined, adjust comments accordingly.

1280 2012-06-27 Stefan Monnier <monnier@iro.umontreal.ca>
1282 * fns.c (maybe_resize_hash_table): Output message when growing the
1283 purify-hashtable.
1285 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
1287 * alloc.c (allocate_string_data): Remove dead code.
1288 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
1289 avoid GCC warning about unused macro.
1291 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
1293 * alloc.c (allocate_string): Omit intervals initialization.
1294 * alloc.c (make_uninit_multibyte_string): Initialize intervals
1295 as in make_pure_string and make_pure_c_string.

1319 * alloc.c (mark_memory): Do not check with -faddress-sanitizer
1320 when building with Clang.
1322 2012-06-26 Stefan Monnier <monnier@iro.umontreal.ca>

1329 _stricmp and _strnicmp.
1330 (HAVE_STRCASECMP, HAVE_STRNCASECMP): Define to 1.
1332 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
1334 * alloc.c (allocate_window): Zero out non-Lisp part of newly
1335 allocated window.

1349 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
1351 * alloc.c: Remove build_string.
1352 * lisp.h: Define build_string as static inline. This provides
1353 a better opportunity to optimize away calls to strlen when the
1354 function is called with compile-time constant argument.
1355 * image.c (imagemagick_error): Convert to build_string.
1356 * w32proc.c (sys_spawnve): Likewise.

1359 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
1361 Use sprintf return value instead of invoking strlen on result.
1362 In the old days this wasn't portable, since some sprintf
1363 implementations returned char *. But they died out years ago and
1364 Emacs already assumes sprintf returns int.
1365 Similarly for float_to_string.
1366 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
1367 * ccl.c (ccl_driver):
1368 * character.c (string_escape_byte8):
1369 * data.c (Fnumber_to_string):
1370 * doprnt.c (doprnt):
1371 * print.c (print_object):
1372 * xdisp.c (message_dolog):
1373 * xfns.c (syms_of_xfns):
1374 Use sprintf or float_to_string result to avoid need to call strlen.
1375 * data.c (Fnumber_to_string):
1376 Use make_unibyte_string, since the string must be ASCII.
1377 * lisp.h, print.c (float_to_string): Now returns int length.
1378 * term.c (produce_glyphless_glyph):
1379 Use sprintf result rather than recomputing it.
1381 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
1382 * Makefile.in (ALL_CFLAGS):
1383 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
1384 * gmalloc.c, regex.c: Include <config.h> unconditionally.

1388 * dispextern.h (xstrcasecmp): Define to library function
1389 strcasecmp if available.
1390 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
1392 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
1394 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):
1395 Avoid comma operator.

1473 Remove unnecessary forward decls.
1475 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
1477 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
1478 * lisp.h (WAIT_READING_MAX): New macro.
1479 * dispnew.c (Fsleep_for, sit_for):
1480 * keyboard.c (kbd_buffer_get_event):
1481 * process.c (Faccept_process_output):
1482 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
1483 This improves on the previous patch, which introduced a bug
1484 when time_t is unsigned and as wide as intmax_t.
1485 See <http://bugs.gnu.org/9000#51>.
1487 2012-06-23 Eli Zaretskii <eliz@gnu.org>
1489 * dispnew.c (sit_for, Fsleep_for):
1490 * keyboard.c (kbd_buffer_get_event):

1503 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
1504 Privately reported by Herbert J. Skuhra.
1505 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
1506 All uses changed.
1507 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
1508 not make_lisp_timeval, when the argument is of type EMACS_TIME.
1510 2012-06-23 Eli Zaretskii <eliz@gnu.org>
1512 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in

1516 language ID in the event parameters.
1518 * w32term.c (w32_read_socket): Put the new keyboard codepage into
1519 event.code, not the obscure "character set ID".

1550 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
1552 Support higher-resolution time stamps (Bug#9000).
1553 The time stamps are only nanosecond-resolution at the C level,
1554 since that's the best that any real-world system supports now.
1555 But they are picosecond-resolution at the Lisp level, as that's
1556 easy, and leaves room for future OS improvements.
1558 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
1559 (LIBES): Use it.
1561 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
1562 Don't get current time unless it's needed.
1564 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
1565 now provides it if it's absent.
1566 (start_atimer): Port to higher-res time stamps.
1567 Check for time stamp overflow. Don't get current time more
1568 often than is needed.
1570 * buffer.h (struct buffer): Buffer modtime now has high resolution.
1571 Include systime.h, not time.h.
1572 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
1574 * dired.c: Include stat-time.h.
1575 (Ffile-attributes): File times now have higher resolution.
1577 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
1578 (struct image): Timestamp now has higher resolution.
1580 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
1581 has at least microseconds now. All uses removed.
1582 (update_frame, update_single_window, update_window, update_frame_1)
1583 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
1585 * editfns.c (time_overflow): Now extern.
1586 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
1587 (float-time, Fformat_time_string, Fcurrent_time_string)
1588 (Fcurrent_time_zone): Accept and generate higher-resolution
1589 time stamps.
1590 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
1591 (decode_time_components, lisp_seconds_argument): New functions.
1592 (make_time): Now static.
1593 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
1594 Report an error if the time is invalid, rather than having the caller
1595 do that.
1597 * fileio.c: Include <stat-time.h>
1598 (Fcopy_file): Copy higher-resolution time stamps.
1599 Prefer to set the time stamp via a file descriptor if that works.
1600 (Fset_file_times, Finsert_file_contents, Fwrite_region)
1601 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
1602 (Fvisited_file_modtime, Fset_visited_file_modtime):
1603 Support higher-resolution time stamps.
1605 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
1607 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
1609 * image.c (prepare_image_for_display, clear_image_cache)
1610 (lookup_image): Port to higer-resolution time stamps.
1612 * keyboard.c (start_polling, bind_polling_period):
1613 Check for time stamp overflow.
1614 (read_char, kbd_buffer_get_event, timer_start_idle)
1615 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
1616 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
1617 Port to higher-resolution time stamps. Do not assume time_t is signed.
1618 (decode_timer): New function. Timers are now vectors of length 9,
1619 not 8, to accommodate the picosecond component.
1620 (timer_check_2): Use it.
1622 * nsterm.m (select_timeout, timeval_subtract): Remove.
1623 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
1624 as they're a bit more accurate and handle overflow better.
1625 (ns_select): Change prototype to be compatible with pselect.
1626 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
1627 * nsterm.h (ns_select): Adjust prototype.
1629 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
1630 us-resolution time stamps.
1631 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
1633 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
1635 * lisp.h (time_overflow): New decl.
1636 (wait_reading_process_output): First arg is now intmax_t, not int,
1637 to accommodate larger waits.
1639 * process.h (struct Lisp_Process.read_output_delay):
1640 Now counts nanoseconds, not microseconds.
1641 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
1642 EMACS_HAS_USECS.
1643 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
1644 (wait_reading_process_output):
1645 Port to ns-resolution time stamps.
1646 (Faccept_process_output, wait_reading_process_output):
1647 Check for time stamp overflow. Do not assume time_t is signed.
1648 (select_wrapper): Remove; we now use pselect.
1649 (Fprocess_attributes): Now generates ns-resolution time stamps.
1651 * sysdep.c: Include utimens.h. Don't include utime.h
1652 or worry about struct utimbuf; gnulib does that for us now.
1653 (gettimeofday): Remove; gnulib provides a substitute.
1654 (make_timeval): New function.
1655 (set_file_times): Now sets ns-resolution time stamps.
1656 New arg FD; all uses changed.
1657 (time_from_jiffies, ltime_from_jiffies, get_up_time)
1658 (system_process_attributes):
1659 Now returns ns-resolution time stamp. All uses changed.
1660 Check for time stamp overflow.
1662 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
1663 provides a substitute now.
1665 * systime.h: Include timespec.h rather than sys/time.h and time.h,
1666 since it guarantees struct timespec.
1667 (EMACS_TIME): Now struct timespec, so that we can support
1668 ns-resolution time stamps.
1669 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
1670 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
1671 (EMACS_USECS): Remove.
1672 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
1673 so multiply the arg by 1000 before storing it.
1674 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
1675 New macros.
1676 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
1677 Port to ns-resolution time stamps.
1678 (EMACS_TIME_NEG_P): Remove; replaced by....
1679 (EMACS_TIME_SIGN): New macro.
1680 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
1681 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
1682 (set_file_times, make_time, lisp_time_argument): Adjust signature.
1683 (make_timeval, make_lisp_time, decode_time_components): New decls.
1684 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
1685 that it mishandled time_t overflow. You can't compare by subtracting!
1686 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
1687 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
1689 * term.c: Include <sys/time.h>.
1690 (timeval_to_Time): New function, for proper overflow wraparound.
1691 (term_mouse_position, term_mouse_click): Use it.
1693 * undo.c (record_first_change): Support higher-resolution time stamps
1694 in the undo buffer.
1695 (Fprimitive_undo): Use them when restoring time stamps.
1697 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
1698 (w32_get_internal_run_time):
1699 Port to higher-resolution Emacs time stamps.
1700 (ltime): Now accepts single 64-bit integer, as that's more convenient
1701 for callers.
1703 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
1705 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
1706 for compatibility with pselect. Support ns-resolution time stamps.
1708 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
1710 * xselect.c (wait_for_property_change, x_get_foreign_selection):
1711 Check for time stamp overflow, and support ns-resolution time stamps.
1713 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
1714 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
1715 (timeval_subtract): Remove; no longer needed.
1716 (XTflash, XTring_bell, x_wait_for_event):
1717 Port to ns-resolution time stamps. Don't assume time_t is signed.
1719 2012-06-22 Chong Yidong <cyd@gnu.org>

1723 2012-06-22 Eli Zaretskii <eliz@gnu.org>
1725 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
1726 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
1727 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
1728 staticidx goes up to 1597 out of 1600 = 0x640.)
1730 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
1732 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
1733 Otherwise, the umask might be mistakenly 0 while handling input signals.
1735 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
1737 * minibuf.c (Fread_string): Bind minibuffer-completion-table.
1739 2012-06-19 Dmitry Antipov <dmantipov@yandex.ru>
1741 * alloc.c, bytecode.c, ccl.c, coding.c, composite.c, data.c, dosfns.c:
1742 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
1743 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
1744 access to `contents' member of Lisp_Vector objects with AREF and ASET
1745 where appropriate.
1747 2012-06-19 Chong Yidong <cyd@gnu.org>
1749 * frame.c (delete_frame): When selecting a frame on a different
1750 text terminal, do not alter the terminal's top-frame.
1752 * xdisp.c (format_mode_line_unwind_data): Record the target
1753 frame's selected window and its terminal's top-frame.
1754 (unwind_format_mode_line): Restore them.
1755 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
1756 Callers changed.
1757 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
1758 since tty frames can be explicitly named.
1759 (prepare_menu_bars): Likewise.
1761 * term.c (Ftty_top_frame): New function.
1763 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
1765 Port byte-code-meter to modern targets.
1766 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
1767 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
1768 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
1769 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
1770 (METER_1, METER_2): Simplify.
1772 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
1774 * data.c (Fdefalias): Return `symbol' (bug#11686).
1776 2012-06-18 Martin Rudalics <rudalics@gmx.at>
1778 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
1779 gets killed during executing of this function (Bug#11665).
1780 Try to always return Qt when the buffer has been actually killed.
1781 (Vkill_buffer_query_functions): In doc-string say that functions
1782 run by this hook should not change the current buffer.
1784 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
1786 Fix recently-introduced process.c problems found by static checking.
1787 * process.c (write_queue_push, write_queue_pop, send_process):
1788 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
1789 (write_queue_pop): Fix pointer signedness problem.
1790 (send_process): Remove unused local.
1792 2012-06-17 Chong Yidong <cyd@gnu.org>
1794 * xdisp.c (redisplay_internal): No need to redisplay terminal
1795 frames that are not on top.
1797 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
1799 * process.c (make_process): Initialize write_queue.
1800 (write_queue_push, write_queue_pop): New functions.

1802 writes (Bug#10815).
1804 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
1806 * lisp.h (eassert): Assume C89 or later.
1807 This removes the need for CHECK.
1808 (CHECK): Remove. Its comments about always evaluating its
1809 argument were confusing, as 'eassert' typically does not evaluate
1810 its argument.
1812 * coding.c (produce_chars): Use ptrdiff_t, not int.
1814 * xterm.c (x_draw_underwave): Check for integer overflow.
1815 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
1817 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
1819 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't
1820 referenced (Bug#11583).

1834 (Finternal_set_lisp_face_attribute, realize_x_face):
1835 Handle wave-style underline face attributes.
1836 * xterm.c (x_draw_underwave): New function.
1837 (x_draw_glyph_string): Use it.
1839 2012-06-16 Juanma Barranquero <lekktu@gmail.com>

1842 ($(BLD)/xml.$(O), $(BLD)/intervals.$(O), $(BLD)/macros.$(O))
1843 ($(BLD)/minibuf.$(O), $(BLD)/regex.$(O), $(BLD)/region-cache.$(O))
1844 ($(BLD)/textprop.$(O), $(BLD)/undo.$(O), $(BLD)/window.$(O))
1845 ($(BLD)/w32select.$(O)): Update dependencies.
1847 2012-06-16 Andreas Schwab <schwab@linux-m68k.org>

1906 2012-06-16 Eli Zaretskii <eliz@gnu.org>
1908 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
1909 If all the glyphs of the glyph row came from strings, and we have no
1910 cursor positioning clues, put the cursor on the first glyph of the
1911 row.
1912 (handle_face_prop): Use chunk-relative overlay string index when
1913 indexing into it->string_overlays array. (Bug#11653)

1931 * .gdbinit (xgetint): Fix recently-introduced paren typo.
1932 Assume USE_2_TAGS_FOR_INTS.
1933 (xreload): Adjust $tagmask width to match recent lisp.h change.
1935 Simplify lisp.h in minor ways that should not affect code.
1936 * lisp.h (USE_2_TAGS_FOR_INTS): Remove, as it was always defined.
1937 (LISP_INT_TAG, case_Lisp_Int, LISP_STRING_TAG, LISP_INT_TAG_P)

1940 (INTTYPEBITS): New macro, for clarity.
1941 (INTMASK, MOST_POSITIVE_FIXNUM): Use it.
1942 (LISP_INT1_TAG, LISP_STRING_TAG, LISP_INT_TAG_P):

1958 * lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct
1959 instead of union.
1960 (XLI, XIL): Define.
1961 (XHASH, XTYPE, XINT, XUINT, make_number, XSET, XPNTR, XUNTAG):
1962 Use them.

1988 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
1989 * alloc.c (make_number) [!defined make_number]:

1997 USE_LSB_TAG now is always defined to be either 0 or 1.
1998 All uses changed.
1999 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
2000 code works fine either way, and efficiency is not a concern here,
2001 as the union type is for debugging, not for production.
2002 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
2003 Use an inline function on all platforms when using the union type,
2004 since this is simpler and 'static inline' can be used portably
2005 within Emacs now.
2006 (LISP_INITIALLY_ZERO): New macro.
2007 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.

2088 2012-06-08 Paul Eggert <eggert@cs.ucla.edu>
2090 * xdisp.c (vmessage): Treat frame message as multibyte.
2091 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
2092 would generate the diagnostic "Making \302\247 buffer-local while
2093 let-bound!".
2095 2012-06-08 Eli Zaretskii <eliz@gnu.org>
2097 * dispnew.c (showing_window_margins_p): Undo last change, which

2111 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
2113 2012-06-08 Eli Zaretskii <eliz@gnu.org>
2115 * alloc.c (allocate_vectorlike): Fix last change.
2117 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
2119 Block-based vector allocation of small vectors.

2138 or equal to VBLOCK_BYTES_MAX.
2139 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
2140 (init_alloc_once): Add call to init_vectors.
2142 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
2144 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
2146 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
2148 * doprnt.c (doprnt): Truncate multibyte char correctly.
2149 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
2150 would mishandle a string argument "Xc" if X was a multibyte
2151 character of length 2: it would truncate after X's first byte
2152 rather than including all of X.
2154 2012-06-06 Chong Yidong <cyd@gnu.org>
2156 * buffer.c (word_wrap): Doc fix.

2203 * minibuf.c (Fassoc_string): Remove duplicate declaration.
2205 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
2206 Convert pctcpu and pctmem to Lisp float properly.
2207 Let the compiler fold better, as 100.0/0x8000 is exact.
2209 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
2211 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
2212 cons_block.

2218 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
2220 For a 'struct window', replace some Lisp_Object fields to
2221 bitfields where appropriate, remove unused fields.
2222 * window.h (struct window): Remove unused 'last_mark_x' and
2223 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
2224 change it's type from Lisp_Object to bitfield.
2225 Change type of 'force_start', 'optional_new_start',
2226 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
2227 fields from Lisp_Object to bitfield. Adjust users accordingly.
2229 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>

2233 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
2234 Use 'float' consistently, rather than 'float' in most places
2235 and 'double' in a couple of places.
2237 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2239 * xdisp.c (handle_stop): Detect whether we have overlay strings
2240 loaded by testing it->current.overlay_string_index to be
2241 non-negative, instead of checking whether n_overlay_strings is
2242 positive. (Bug#11587)
2244 2012-05-31 Chong Yidong <cyd@gnu.org>
2246 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

2250 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2252 * search.c (search_buffer): Remove calls to
2253 r_alloc_inhibit_buffer_relocation, as it is now called by
2254 maybe_unify_char, which was the cause of relocation of buffer text
2255 in bug#11519.
2257 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2259 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
2260 for the duration of call to load_charset, to avoid problems with
2261 callers of maybe_unify_char that access buffer text through C
2262 pointers.
2264 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
2265 decrement the inhibition flag, instead of just setting or
2266 resetting it.
2268 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2270 Remove obsolete '#define static' cruft.
2271 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
2272 This #undef was "temporary" in 2000; it is no longer needed
2273 now that '#define static' has gone away.
2274 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
2275 (gray_bitmap_bits): Remove; no longer needed.
2276 All uses replaced with definiens.

2288 (safe_bcopy): Remove decl; no longer has that name.
2289 (main): Coalesce #if into single bit of code, for simplicity.
2290 Cast pointers to uintptr_t, since standard libraries want integers
2291 and not pointers.
2292 * lisp.h (__executable_start): New decl.
2294 2012-05-31 Glenn Morris <rgm@gnu.org>

2315 * lread.c (read1): Tiny simplification.
2317 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
2319 Do not create empty overlays with the evaporate property (Bug#9642).
2320 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
2321 Bug#9642, but explicitly check that the buffer the overlay would
2322 be moved to is live and rearrange lines to make sure that errors
2323 will not put the overlay in an inconsistent state.
2324 (Fdelete_overlay): Cosmetics.
2326 2012-05-28 Eli Zaretskii <eliz@gnu.org>
2328 * w32term.c (my_bring_window_to_top): New function.
2329 (x_raise_frame): Use handle returned by DeferWindowPos, which
2330 could be different from the original one.
2331 Call my_bring_window_to_top instead of my_set_foreground_window.
2332 (Bug#11513)
2334 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
2335 by calling BringWindowToTop.

2338 (WM_EMACS_END): Increase by one.
2340 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
2342 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
2343 This avoids undefined behavior that might cause the eassert
2344 to not catch an out-of-range value.
2346 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
2348 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
2349 Update dependencies.
2351 2012-05-27 Eli Zaretskii <eliz@gnu.org>

2358 when referring to sectname field in printf format.
2360 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
2362 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
2363 Only r_alloc_inhibit_buffer_relocation needed to be added;
2364 the others were already declared.
2366 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
2367 before checking whether it's out of range. Put the check inside
2368 eassert. See
2369 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
2371 2012-05-27 Ken Brown <kbrown@cornell.edu>
2373 * callproc.c (Fcall_process): Restore a line that was accidentally
2374 commented out in the 2011-02-13 change (bug#11547).
2376 2012-05-27 Eli Zaretskii <eliz@gnu.org>
2378 * lisp.h [REL_ALLOC]: Add prototypes for external functions
2379 defined on ralloc.c.
2381 * buffer.c [REL_ALLOC]: Remove prototypes of
2382 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
2383 they are now on lisp.h.
2385 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
2387 * search.c (search_buffer): Use it to inhibit relocation of buffer
2388 text while re_search_2 is doing its job, because re_search_2 is
2389 passed C pointers to buffer text. (Bug#11519)
2391 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
2392 Update value to 24.
2394 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
2395 state after an additional call to move_it_in_display_line_to, keep
2396 the values of it->max_ascent and it->max_descent found for the
2397 entire line.
2398 (pos_visible_p): Revert the comparison against bottom_y to what it
2399 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
2400 (Bug#11464)
2402 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
2404 Fix coding-related core dumps with gcc -ftrapv.
2405 The code was computing A - B, where A and B are pointers, and B is
2406 random garbage. This can lead to core dumps on platforms that
2407 have special pointer registers, and it also leads to core dumps on
2408 x86-64 when compiled with gcc -ftrapv. The fix is to compute
2409 A - B only when B is initialized properly.
2410 * coding.c (coding_set_source, coding_set_destination): Return void.
2411 (coding_change_source, coding_change_destinations): New functions,
2412 with the old behaviors of coding_set_source and coding_set_destination.
2413 All callers that need an offset changed to use these new functions.
2415 2012-05-26 Glenn Morris <rgm@gnu.org>
2417 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
2419 2012-05-26 Eli Zaretskii <eliz@gnu.org>
2421 Extend mouse support on W32 text-mode console.
2422 * xdisp.c (draw_row_with_mouse_face):
2423 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
2425 * w32console.c: Include window.h.
2426 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
2427 New functions.
2428 (initialize_w32_display): Initialize mouse-highlight data.
2430 * w32inevt.c: Include termchar.h and window.h.
2431 (do_mouse_event): Support mouse-autoselect-window. When the mouse
2432 moves, call note_mouse_highlight. If help_echo changed, call
2433 gen_help_event to produce help-echo message in the echo area.
2434 Call clear_mouse_face if mouse_face_hidden is set in the mouse
2435 highlight info.
2437 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
2439 * lread.c (read1): Simplify slightly to avoid an overflow warning
2440 with GCC 4.7.0 on x86-64.
2442 2012-05-26 Eli Zaretskii <eliz@gnu.org>
2444 * bidi.c (bidi_mirror_char): Revert last change: an int is
2445 definitely wide enough here.
2447 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
2449 Fix integer width and related bugs (Bug#9874).
2450 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
2451 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
2452 (string_bytes, check_sblock, allocate_string_data):

2457 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
2458 (mark_vectorlike):
2459 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2460 (allocate_pseudovector):
2461 Use int, not EMACS_INT, where int is wide enough.
2462 (inhibit_garbage_collection, Fgarbage_collect):
2463 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2464 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
2465 int might not be wide enough.
2466 (bidi_cache_search, bidi_cache_find, bidi_init_it)

2470 (bidi_level_of_next_char, bidi_move_to_visually_next):
2471 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2472 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
2473 (Fkill_buffer, Fset_buffer_major_mode)
2474 (advance_to_char_boundary, Fbuffer_swap_text)

2477 (overlay_strings, recenter_overlay_lists)
2478 (adjust_overlays_for_insert, adjust_overlays_for_delete)
2479 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
2480 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
2481 (Foverlay_recenter, last_overlay_modification_hooks_used)
2482 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
2483 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2484 (validate_region): Omit unnecessary test for b <= e,
2485 since that's guaranteed by the previous test.
2486 (adjust_overlays_for_delete): Avoid pos + length overflow.
2487 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
2488 (report_overlay_modification):
2489 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2490 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
2491 Omit pointer cast, which isn't needed anyway, and doesn't work
2492 after the EMACS_INT -> ptrdiff_t change.
2493 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
2494 * buffer.h: Adjust decls to match defn changes elsewhere.

2499 not int, to avoid needless 32-bit limit on 64-bit hosts.
2500 (exec_byte_code): Use tighter memory-full test, one that checks
2501 for alloca overflow. Don't compute the address of the object just
2502 before an array, as that's not portable. Use EMACS_INT, not
2503 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
2504 * callint.c (Fcall_interactively):
2505 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2506 * callproc.c (call_process_kill, Fcall_process):
2507 Don't assume pid_t fits into an Emacs fixnum.
2508 (call_process_cleanup, Fcall_process, child_setup):

2515 * casefiddle.c (casify_object, casify_region, operate_on_word)
2516 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
2517 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2518 (casify_object): Avoid integer overflow when overallocating buffer.
2519 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
2520 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
2521 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
2522 * category.h (CATEGORYP): Don't assume arg is nonnegative.
2523 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
2524 integers are now checked earlier. All uses replaced with XINT.
2525 (ccl_driver):
2526 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2527 For CCL_MapSingle, check that content and value are in int range.
2528 (ccl_driver, Fregister_code_conversion_map):
2529 Check that Vcode_version_map_vector is a vector.
2530 (resolve_symbol_ccl_program): Check that vector header is in range.
2531 Always copy the vector, so that we can check its contents reliably
2532 now rather than having to recheck each instruction as it's being
2533 executed. Check that vector words fit in 'int'.
2534 (ccl_get_compiled_code, Fregister_ccl_program)
2535 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
2536 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
2537 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
2538 contents are in range.
2539 (Fccl_execute_on_string): Check that status is in range.
2540 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
2541 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
2542 Accept and return EMACS_INT, not int, because callers can pass values
2543 out of 'int' range.
2544 (c_string_width, strwidth, lisp_string_width, chars_in_text)
2545 (multibyte_chars_in_text, parse_str_as_multibyte)

2548 (string_escape_byte8, Fget_byte):
2549 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2550 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
2551 avoid mishandling large integers.
2552 * character.h: Adjust decls to match defn changes elsewhere.
2553 * charset.c (load_charset_map_from_file, find_charsets_in_text)

2556 (load_charset_map_from_file): Redo idx calculation to avoid overflow.

2558 Don't assume fixnum fits in int.
2559 (load_charset_map_from_vector, Fmap_charset_chars):

2561 (Fdefine_charset_internal): Check ranges here, more carefully.
2562 Don't rely on undefined behavior with signed left shift overflow.
2563 Don't assume unsigned int fits into fixnum, or that fixnum fits
2564 into unsigned int. Don't require max_code to be a valid fixnum;
2565 that's not true for gb10830 4-byte on a 32-bit host. Allow
2566 invalid_code to be a cons, for the same reason. Require code_offset
2567 to be a character. Avoid int overflow if max_char is close
2568 to INT_MAX.
2569 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
2570 this is intended anyway and avoids some undefined behavior.
2571 (load_charset_map): Pass unsigned, not int, as 2nd arg of
2572 INDEX_TO_CODE_POINT, as that's what it expects.
2573 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
2574 * charset.h (DECODE_CHAR): Return int, not unsigned;
2575 this is what was intended anyway, and it avoids undefined behavior.
2576 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
2577 integer-overflow issues.
2578 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
2579 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
2580 where the argument is EMACS_INT, and this behavior is not intended.
2581 * chartab.c (Fmake_char_table, Fset_char_table_range)
2582 (uniprop_get_decoder, uniprop_get_encoder):
2583 Don't assume fixnum fits in int.
2584 * cmds.c (move_point): New function, that does the gist of
2585 Fforward_char and Fbackward_char, but does so while checking
2586 for integer overflow more accurately.
2587 (Fforward_char, Fbackward_char): Use it.
2588 (Fforward_line, Fend_of_line, internal_self_insert)
2589 (internal_self_insert):
2590 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2591 Fix a FIXME, by checking for integer overflow when calculating
2592 target_clm and actual_clm.

2627 Don't access memory outside of the args array.
2628 (Fdefine_coding_system_internal): Check for charset-id overflow.
2629 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
2630 result of ENCODE_CHAR.

2649 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
2650 Do not attempt to compute the address of the object just before a

2652 (Faref, Faset):
2653 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2654 (Faset): Use int, not EMACS_INT, where int is wide enough.

3371 2012-05-14 Glenn Morris <rgm@gnu.org>

3374 Put "libexec" before "bin", for the sake of init_callproc_1.
3376 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3378 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
3380 * unexaix.c: Port to more-recent AIX compilers.
3381 (report_error, report_error_1, make_hdr, copy_sym)
3382 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
3383 Make arguments const char *, not char *, to avoid violations of C
3384 standard and to fix some AIX warnings reported by Gilles Pion.
3386 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3388 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
3389 already have overlays loaded.
3390 (handle_single_display_spec): Before returning without displaying
3391 fringe bitmap, synchronize the bidi iterator with the main display
3392 iterator, by calling iterate_out_of_display_property.
3393 (iterate_out_of_display_property): Detect buffer iteration by
3394 testing that it->string is a Lisp string.
3395 (get_next_display_element): When the current object is exhausted,
3396 and there's something on it->stack, call set_iterator_to_next to
3397 proceed with what's on the stack, instead of returning zero.
3398 (set_iterator_to_next): If called at the end of a Lisp string,
3399 proceed to consider_string_end without incrementing string
3400 position. Don't increment display vector index past the end of
3401 the display vector. (Bug#11417)
3402 (pos_visible_p): Don't report a position visible when move_it_to
3403 stopped at the last line of window, which happens to be scanned
3404 backwards by the bidi iteration. (Bug#11464)
3406 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3408 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
3409 and right-margin display specs even if the spec is invalid or we
3410 are on a TTY, and thus unable to display on the fringes.
3411 That's because the text with the property will not be displayed anyway,
3412 so we need to signal to the caller that this is a "replacing"
3413 display spec. This fixes display when the spec is invalid or we
3414 are on a TTY.
3416 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3418 * unexaix.c (make_hdr): Fix typo in prototype.
3419 This bug broke the build on AIX. Problem reported by Gilles Pion.
3421 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
3423 * keyboard.c (kbd_buffer_get_event): Read special events also in
3424 batch mode. (Bug#11415)
3426 2012-05-12 Glenn Morris <rgm@gnu.org>
3428 * ns.mk: Update for ns_appbindir no longer having trailing "/".
3430 2012-05-12 Eli Zaretskii <eliz@gnu.org>
3432 * lisp.mk (lisp): Add newcomment.elc.
3434 2012-05-12 Glenn Morris <rgm@gnu.org>
3436 * Makefile.in (MKDIR_P): New, set by configure.
3437 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
3439 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
3441 Remove unused function hourglass_started.
3442 * dispextern.h (hourglass_started):
3443 * w32fns.c (hourglass_started):
3444 * xdisp.c (hourglass_started): Remove.
3446 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
3448 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
3449 Update dependencies.
3451 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
3453 * xgselect.c (xg_select): Put maxfds+1 into a var.
3454 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
3456 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
3458 2012-05-10 Dave Abrahams <dave@boostpro.com>
3460 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
3461 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
3463 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
3465 * dbusbind.c (xd_registered_buses): New internal Lisp object.
3466 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
3467 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
3468 Initialize xd_registered_buses.
3470 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
3472 Untag more efficiently if USE_LSB_TAG.
3473 This is based on a proposal by YAMAMOTO Mitsuharu in
3474 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
3475 For an admittedly artificial (nth 8000 longlist) benchmark on
3476 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
3477 Emacs's overall text size by 1%.
3478 * lisp.h (XUNTAG): New macro.
3479 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
3480 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
3481 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
3482 * eval.c (Fautoload):
3483 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
3484 * frame.h (XFRAME): Use XUNTAG.
3486 Port recent dbusbind.c changes to 32-bit --with-wide-int.
3487 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
3488 Remove unportable assumptions about print widths of types like
3489 dbus_uint32_t.
3490 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
3491 intptr_t when converting between pointer and integer, to avoid GCC
3492 warnings about wrong width.
3494 2012-05-09 Eli Zaretskii <eliz@gnu.org>
3496 * w32proc.c (new_child): Force Windows to reserve only 64KB of
3497 stack for each reader_thread, instead of defaulting to 8MB
3498 determined by the linker. This avoids failures in creating
3499 subprocesses on Windows 7, see the discussion in this thread:
3500 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
3502 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
3504 Fix up display of the *Minibuf-0* buffer in the mini window.
3505 * keyboard.c (read_char): Don't clear the echo area if there's no
3506 message to clear.
3507 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
3508 contents of *Minibuf-0*) if there's no message displayed in its stead.
3510 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
3512 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
3513 batch mode.
3515 2012-05-06 Chong Yidong <cyd@gnu.org>
3517 * lisp.mk (lisp): Update.
3519 2012-05-05 Jim Meyering <meyering@redhat.com>
3521 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
3523 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
3525 * data.c (PUT_ERROR): New macro.
3526 (syms_of_data): Use it. Add new error type `user-error'.
3527 * undo.c (user_error): New function.
3528 (Fprimitive_undo): Use it.
3529 * print.c (print_error_message): Adjust print style for `user-error'.
3530 * keyboard.c (user_error): New function.
3531 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
3533 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
3535 Do not limit current-time-string to years 1000..9999.
3536 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
3537 (Fcurrent_time_string): Support any year that is supported by the
3538 underlying localtime representation. Don't use asctime, as it
3539 has undefined behavior for years outside the range -999..9999.
3541 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
3543 Fix race conditions involving setenv, gmtime, localtime, asctime.
3544 Without this fix, interrupts could mess up code that uses these
3545 nonreentrant functions, since setting TZ invalidates existing
3546 tm_zone or tzname values, and since most of these functions return
3547 pointers to static storage.
3548 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
3549 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
3550 Grow the critical sections to include not just invoking
3551 localtime/gmtime, but also accessing these functions' results
3552 including their tm_zone values if any, and any related TZ setting.
3553 (format_time_string): Last arg is now struct tm *, not struct tm **,
3554 so that the struct tm is saved in the critical section.
3555 All callers changed. Simplify allocation of initial buffer, partly
3556 motivated by the fact that memory allocation needs to be outside
3557 the critical section.
3559 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
3561 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
3562 with RESET_INTERVAL.
3564 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
3565 Remove duplicated buffer name initialization.
3567 2012-05-02 Jim Meyering <jim@meyering.net>
3569 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
3571 * xfns.c (x_window): Use xstrdup (Bug#11375).
3573 2012-05-02 Eli Zaretskii <eliz@gnu.org>
3575 * xdisp.c (pos_visible_p): If already at a newline from the
3576 display string before the 'while' loop, don't walk back the glyphs
3577 from it3.glyph_row. Solves assertion violation when the display
3578 string begins with a newline (egg.el). (Bug#11367)
3580 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
3582 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
3583 Move to simple.el.
3585 2012-05-01 Glenn Morris <rgm@gnu.org>
3587 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
3588 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
3589 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
3590 All were removed before 23.1.
3592 * dispnew.c: Remove HAVE_LIBNCURSES test;
3593 it is always true on relevant platforms.
3595 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
3596 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
3598 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
3600 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
3602 * .gdbinit (xpr): Remove checks for no longer existing misc types.
3603 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
3604 Remove.
3606 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
3608 Do not avoid creating empty evaporating overlays (Bug#9642).
3609 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
3610 That is, do not delete an evaporating overlay if it becomes
3611 empty after its bounds are adjusted to fit within its buffer.
3612 This fix caused other problems, and I'm reverting it until we get
3613 to the bottom of them.
3615 2012-04-27 Chong Yidong <cyd@gnu.org>
3617 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
3619 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3621 * xdisp.c (pos_visible_p): If the window start position is beyond
3622 ZV, start the display from buffer beginning. Prevents assertion
3623 violation in init_iterator when the minibuffer window is scrolled
3624 via the scroll bar.
3626 * window.c (window_scroll_pixel_based): Likewise.
3628 2012-04-27 Chong Yidong <cyd@gnu.org>
3630 * keymap.c (where_is_internal): Doc fix (Bug#10872).
3632 2012-04-27 Glenn Morris <rgm@gnu.org>
3634 * fileio.c (Fcopy_file, Fset_file_selinux_context):
3635 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
3637 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3639 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
3640 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
3642 2012-04-26 Eli Zaretskii <eliz@gnu.org>
3644 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
3645 display element, check also the underlying string or buffer
3646 character. (Bug#11341)
3648 * w32menu.c: Include w32heap.h.
3649 (add_menu_item): If the call to AppendMenuW (via
3650 unicode_append_menu) fails, disable Unicode menus only if we are
3651 running on Windows 9X/Me.
3653 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
3655 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
3656 (xgetint): Add missing shift for LSB tags.
3658 2012-04-24 Martin Rudalics <rudalics@gmx.at>
3660 * keyboard.c (read_char): Don't wipe echo area for select window
3661 events: These might get delayed via `mouse-autoselect-window'
3662 (Bug#11304).
3664 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
3666 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
3667 manipulation of :loaded-from data.
3669 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
3671 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
3672 now a cons (bug#11311).
3674 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
3676 Do not create empty overlays with the evaporate property (Bug#9642).
3677 * buffer.c (Fmove_overlay): Delete an evaporating overlay
3678 if it becomes empty after its bounds are adjusted to fit within
3679 its buffer. Without this fix, in a nonempty buffer (let ((o
3680 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
3681 yields an empty overlay that has the evaporate property, which is
3682 not supposed to happen.
3684 Fix minor GTK3 problems found by static checking.
3685 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
3686 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
3687 (struct _EmacsFixedClass, emacs_fixed_get_type):
3688 Move decls here from emacsgtkfixed.h, since they needn't be public.

3690 (emacs_fixed_class_init): Omit unused local.
3691 (emacs_fixed_child_type): Remove; unused.

3693 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
3694 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
3695 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
3696 (EMACS_FIXED_GET_CLASS): Remove; unused.
3697 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
3699 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
3700 Problem reported by Juanma Barranquero for Windows -Wunused-function.
3702 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
3704 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
3705 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
3706 (__malloc_size_t, __malloc_ptrdiff_t):
3707 Remove. All uses removed, replaced by the definiens if needed,
3708 since we can assume C89 or better now.
3709 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
3710 (protect_malloc_state, align, get_contiguous_space)
3711 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
3712 (malloc_atfork_handler_child, malloc_enable_thread)

3716 (special_realloc, _realloc_internal_nolock, _realloc_internal)
3717 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
3718 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
3719 Define using prototypes, not old style.
3720 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
3721 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
3722 (align): Don't assume that signed integer overflow wraps around.
3723 Omit unused local var.
3724 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
3725 (_free_internal_nolock, memalign, mallochook, reallochook):
3726 Omit no-longer-needed casts.
3727 (valloc): Use getpagesize, not __getpagesize.
3728 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
3729 (struct hdr): The 'magic' member is now size_t, not unsigned long.
3731 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
3733 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
3735 Move functions from C to Lisp. Make non-blocking method calls
3736 the default. Implement further D-Bus standard interfaces.

3768 (Fdbus_register_signal, Fdbus_register_method): Move to dbus.el.
3769 (xd_read_message_1): Obey new structure of Vdbus_registered_objects.
3770 (xd_read_queued_messages): Obey new structure of Vdbus_registered_buses.
3771 (Vdbus_compiled_version, Vdbus_runtime_version)
3772 (Vdbus_message_type_invalid, Vdbus_message_type_method_call)
3773 (Vdbus_message_type_method_return, Vdbus_message_type_error)

3784 * alloc.c: Handle unusual debugging option combinations.
3785 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
3786 since the two debugging options are incompatible.
3787 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
3788 is defined.
3789 (mem_init, mem_insert, mem_insert_fixup):
3790 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
3791 (NEED_MEM_INSERT): Remove; no longer needed.
3793 2012-04-22 Leo Liu <sdl.web@gmail.com>

3799 * sysdep.c [__FreeBSD__]: Minor cleanups.
3800 (list_system_processes, system_process_attributes) [__FreeBSD__]:
3801 Use Emacs indenting style more consistently. Avoid some casts.
3802 Use 'double' consistently rather than mixing 'float' and 'double'.
3804 2012-04-21 Eduard Wiebe <usenet@pusto.de>
3806 * sysdep.c (list_system_processes, system_process_attributes):
3807 Add implementation for FreeBSD (Bug#5243).

3821 is nil.
3822 (print_object): Check for cycles even when print-circle is nil and

3825 2012-04-20 Chong Yidong <cyd@gnu.org>
3827 * process.c (wait_reading_process_output): If EIO occurs on a pty,

3840 (set_cursor_from_row): If called for a mode-line or header-line
3841 row, return zero immediately.
3842 (try_cursor_movement): If inside continuation line, don't back up
3843 farther than the first row after the header line, if any.
3844 Don't consider the header-line row as "partially visible", even if
3845 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
3847 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
3849 * lread.c (lisp_file_lexically_bound_p): Fix hang at ";-*-\n"

3879 2012-04-16 Paul Eggert <eggert@cs.ucla.edu>
3881 Fix minor alloc.c problems found by static checking.
3882 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
3883 New extern decls, to avoid calling undeclared functions.
3884 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
3885 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
3886 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
3887 (NEED_MEM_INSERT): New macro.
3888 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
3889 Remove one incorrect comment and fix another.

3894 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
3895 (r_alloc_sbrk): Now static.
3897 Improve ralloc.c interface checking.
3898 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
3899 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
3900 (r_alloc_free) [REL_ALLOC]: Move decls from here ...

3902 [REL_ALLOC]: ... to here, to check interface.
3903 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
3904 Remove decls. This fixes an "It stinks!".
3906 * alloc.c (which_symbols): Fix alignment issue / type clash.
3908 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
3910 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
3911 (struct Lisp_Misc_Any): Likewise.

3921 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
3923 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
3924 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
3925 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
3926 * s/netbsd.h, s/sol2-6.h:
3927 Remove definition of GC_MARK_STACK, since the default now works.
3928 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
3929 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
3930 no longer the default.
3931 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
3933 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
3935 * lread.c (lisp_file_lexically_bound_p):
3936 Fix hang at ";-*-\n" (bug#11238).
3938 2012-04-14 Eli Zaretskii <eliz@gnu.org>
3940 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row

3945 * nsterm.m (constrainFrameRect): Always constrain when there is only
3946 one screen (Bug#10962).
3948 2012-04-13 Ken Brown <kbrown@cornell.edu>
3950 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
3952 2012-04-13 Reuben Thomas <rrt@sc3d.org>
3954 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
3956 2012-04-11 Daniel Colascione <dancol@dancol.org>
3958 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
3959 against is gone. It's better to use vfork now so that when Cygwin
3960 gains a new, working vfork, we use it automatically (bug#10398).
3962 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
3964 * window.c (save_window_save): Obey window-point-insertion-type.
3966 2012-04-11 Glenn Morris <rgm@gnu.org>

3976 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
3977 (force_quit_count): New var.
3978 (handle_interrupt): Use it.
3980 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
3982 * w32.c (w32_delayed_load): Record the full path of the library
3983 being loaded (bug#10424).
3985 2012-04-09 Glenn Morris <rgm@gnu.org>
3987 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
3988 not just in the obarray, before snarfing them. (Bug#11036)
3990 * Makefile.in ($(leimdir)/leim-list.el):
3991 Pass EMACS rather than BUILT_EMACS.
3993 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
3995 * process.c (make_process):
3996 * process.h: Add integer `gnutls_handshakes_tried' member to
3997 process struct.
3999 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
4000 Add convenience `GNUTLS_LOG2i' macro.
4002 * gnutls.c (gnutls_log_function2i): Convenience log function.
4003 (emacs_gnutls_read): Use new log functions,
4004 `gnutls_handshakes_tried' process member, and
4005 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
4006 attempts per process (connection).
4008 2012-04-09 Chong Yidong <cyd@gnu.org>
4010 * eval.c (Fuser_variable_p, user_variable_p_eh)
4011 (lisp_indirect_variable): Functions deleted.
4012 (Fdefvar): Caller changed.
4014 * callint.c (Finteractive, Fcall_interactively):
4015 * minibuf.c (Fread_variable): Callers changed.
4017 2012-04-09 Eli Zaretskii <eliz@gnu.org>
4019 * xdisp.c (set_cursor_from_row): If the display string appears in
4020 the buffer at position that is closer to point than the position
4021 after the display string, display the cursor on the first glyph of
4022 the display string. Fixes cursor display when a 'display' text
4023 property immediately follows invisible text. (Bug#11094)
4025 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
4027 composite.c: use 'double' consistently
4028 * composite.c (get_composition_id): Use 'double' consistently
4029 instead of converting 'float' to 'double' and vice versa; this is
4030 easier to understand and avoids a GCC warning.
4032 2012-04-09 Glenn Morris <rgm@gnu.org>
4034 * Makefile.in: Generate leim-list with bootstrap-emacs, in
4035 preparation for dumping it with emacs. (Bug#4789)

4044 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
4046 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
4047 proper alignment.

4051 * xml.c (init_libxml2_functions) [WINDOWSNT]:
4052 Remove unused local variable.
4054 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>

4057 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
4058 (mark_memory): Mark Lisp_Objects only if pointers might hide in
4059 objects, as mark_maybe_pointer will catch them otherwise.
4060 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
4061 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
4063 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
4065 Fix typo that broke non-Windows builds.
4066 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
4068 2012-04-07 Eli Zaretskii <eliz@gnu.org>
4070 Support building on MS-Windows with libxml2.
4072 * makefile.w32-in (OBJ2): Add xml.$(O).
4073 (GLOBAL_SOURCES): Add xml.c.
4074 ($(BLD)/xml.$(O)): New dependency list.
4076 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
4077 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
4078 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
4079 [!WINDOWSNT]: New macros.
4080 (init_libxml2_functions, libxml2_loaded_p): New functions.
4081 (parse_region): Call fn_xmlCheckVersion instead of using the macro
4082 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
4083 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
4084 Calls xmlCleanupParser only if libxml2 was loaded (or statically
4085 linked in).
4086 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
4087 Call init_libxml2_functions before calling libxml2 functions.
4088 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
4090 * emacs.c: Don't include libxml/parser.h.
4091 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
4092 xmlCleanupParser directly.
4094 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
4096 2012-04-07 Eli Zaretskii <eliz@gnu.org>
4098 * indent.c (Fvertical_motion): If there is a display string at
4099 point, use it.vpos to compute how many lines to backtrack after
4100 move_it_to point. (Bug#11133)
4102 2012-04-06 Eli Zaretskii <eliz@gnu.org>
4104 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
4105 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
4106 about subtle differences between FETCH_CHAR* and STRING_CHAR*
4107 macros related to unification of CJK characters. For the details,
4108 see the discussion following the message here:
4109 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
4111 2012-04-04 Chong Yidong <cyd@gnu.org>
4113 * keyboard.c (Vdelayed_warnings_list): Doc fix.
4115 2012-04-01 Eli Zaretskii <eliz@gnu.org>
4117 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
4118 instead of alloca. (Bug#11138)
4120 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
4122 * w32menu.c (is_simple_dialog): Properly check lisp types.
4123 (Bug#11141)
4125 2012-03-31 Eli Zaretskii <eliz@gnu.org>
4127 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
4128 position we get to after a call to move_it_to fails the
4129 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
4130 only if we wind up in a string from display property. (Bug#11063)
4132 * window.c (Fdelete_other_windows_internal): Invalidate the row
4133 and column information about mouse highlight, so that redisplay
4134 restores it after reallocating the glyph matrices. (Bug#7464)
4136 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
4137 string comes from a `display' text property, use the buffer
4138 position of that property as if we actually saw that position in
4139 the row's glyphs.
4140 (move_it_by_lines): Remove the assertion that
4141 "it->current_x == 0 && it->hpos == 0" which can be legitimately
4142 violated when there's a before-string at the beginning of a line.
4143 (Bug#11063)
4145 2012-03-30 Eli Zaretskii <eliz@gnu.org>
4147 * xdisp.c (append_space_for_newline): If the default face was
4148 remapped, use the remapped face for the appended newline.
4149 (extend_face_to_end_of_line): Use the remapped default face for
4150 extending the face to the end of the line.
4151 (display_line): Call extend_face_to_end_of_line when the default
4152 face was remapped. (Bug#11068)
4154 2012-03-29 Eli Zaretskii <eliz@gnu.org>
4156 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
4158 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
4160 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
4162 2012-03-27 Glenn Morris <rgm@gnu.org>
4164 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
4165 Doc fixes.
4167 2012-03-26 Kenichi Handa <handa@m17n.org>
4169 * dispextern.h (struct glyph): Fix previous change. Change the
4170 bit length of glyphless.ch to 25 (Bug#11082).
4172 2012-03-26 Chong Yidong <cyd@gnu.org>
4174 * keyboard.c (Vselection_inhibit_update_commands): New variable.
4175 (command_loop_1): Use it; inhibit selection update for
4176 handle-select-window too (Bug#8996).
4178 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
4180 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
4182 2012-03-25 Kenichi Handa <handa@m17n.org>
4184 * dispextern.h (struct glyph): Change the bit length of
4185 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
4187 2012-03-24 Eli Zaretskii <eliz@gnu.org>
4189 * s/ms-w32.h (tzname): Include time.h before redirecting to
4190 _tzname. Fixes the MSVC build. (Bug#9960)
4192 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
4194 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
4195 characters.
4197 * xterm.c (XTread_socket): Only modify handling_signal if
4198 !SYNC_INPUT. (Bug#11080)
4200 2012-03-23 Eli Zaretskii <eliz@gnu.org>
4202 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
4203 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
4204 when fetching a multibyte character consumes more bytes than
4205 CHAR_BYTES returns, due to unification of CJK characters in
4206 string_char. (Bug#11073)
4208 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
4210 * process.c (wait_reading_process_output): Handle pty disconnect
4211 by refraining from sending oneself a SIGCHLD (bug#10933).

4217 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
4218 Mark string as coming from a prefix property.
4219 (handle_face_prop): Use default face for prefix strings (Bug#4281).
4220 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
4222 2012-03-21 Chong Yidong <cyd@gnu.org>
4224 * xfaces.c (Vface_remapping_alist): Doc fix.
4226 2012-03-20 Eli Zaretskii <eliz@gnu.org>
4228 * w32proc.c (Fw32_set_console_codepage)
4229 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
4230 Doc fixes.
4232 2012-03-20 Chong Yidong <cyd@gnu.org>
4234 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc

4240 it fit in a valid range (Bug#11003).
4242 2012-03-18 Eli Zaretskii <eliz@gnu.org>
4244 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
4245 that is not from display property, accept the row as a "cursor
4246 row" if one of the string's character has a non-nil `cursor'
4247 property. Fixes cursor positioning when there are newlines in
4248 overlay strings, e.g. in icomplete.el. (Bug#11035)
4250 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
4252 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
4254 2012-03-12 Chong Yidong <cyd@gnu.org>
4256 * eval.c (inhibit_lisp_code): Rename from
4257 inhibit_window_configuration_change_hook; move from window.c.
4259 * xfns.c (unwind_create_frame_1, Fx_create_frame):
4260 * window.c (run_window_configuration_change_hook)
4261 (syms_of_window): Callers changed.
4263 2012-03-11 Chong Yidong <cyd@gnu.org>
4265 * keymap.c (Fkey_description): Doc fix (Bug#9700).
4267 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).

4271 * frame.c (other_visible_frames): Don't assume the selected frame
4272 is visible (Bug#10955).
4274 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
4276 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
4278 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
4280 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
4281 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
4282 zero (Bug#10954).
4284 2012-03-03 Glenn Morris <rgm@gnu.org>
4286 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
4288 2012-03-02 Eli Zaretskii <eliz@gnu.org>
4290 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
4291 position past the first glyph_row that ends at ZV. (Bug#10902)
4292 (redisplay_window, next_element_from_string): Fix typos in
4293 comments.
4294 (redisplay_window): Pass to move_it_vertically the margin in
4295 pixels, not in screen lines.
4297 2012-03-02 Glenn Morris <rgm@gnu.org>
4299 * buffer.c (buffer-list-update-hook): Doc fix.
4301 2012-02-29 Eli Zaretskii <eliz@gnu.org>
4303 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
4304 push_it before setting up the iterator for the first overlay
4305 string, even if we have an empty string loaded.
4306 (next_overlay_string): If there's an empty string on the iterator
4307 stack, pop the stack. (Bug#10903)
4309 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
4311 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
4312 Suggested by Stefan Monnier in
4313 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
4314 * alloc.c (widen_to_Lisp_Object): New static function.
4315 (mark_memory): Also mark Lisp_Objects by fetching pointer words
4316 and widening them to Lisp_Objects. This would work even if
4317 USE_LSB_TAG is defined and wide integers are used, which might
4318 happen in a future version of Emacs.
4320 2012-02-25 Chong Yidong <cyd@gnu.org>
4322 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
4323 Doc fix.
4325 * xselect.c (Fx_selection_exists_p): Doc fix.
4326 (x_clipboard_manager_save_all): Print an informative message
4327 before saving to clipboard manager.
4329 2012-02-24 Chong Yidong <cyd@gnu.org>

4359 when computing $valmask.
4361 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
4362 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
4363 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
4364 It's useless in that case, and it can cause problems on hosts
4365 that allocate halves of EMACS_INT values separately.
4366 Reported by Dan Horák. Diagnosed by Andreas Schwab in
4367 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
4368 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
4369 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
4370 it avoids undefined behavior on hosts where shifting right by more
4371 than the word width has undefined behavior.
4373 2012-02-19 Chong Yidong <cyd@gnu.org>
4375 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
4376 (Funhandled_file_name_directory, Ffile_name_as_directory)

4418 * window.c (Fdelete_window_internal): Invalidate the mouse
4419 highlight (Bug#9904).

4453 * buffer.c (Fbuffer_local_variables)
4454 (buffer_lisp_local_variables): Handle unbound vars correctly;
4455 don't let Qunbound leak into Lisp.
4457 2012-02-07 Glenn Morris <rgm@gnu.org>
4459 * image.c (Fimagemagick_types): Doc fix.

4497 * character.c (char_width): Return EMACS_INT, not int.
4498 (char_width, c_string_width): Check for overflow when
4499 computing the width; this is possible now that individual
4500 characters can have unbounded width. Problem introduced

5036 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
5037 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in

5155 is set, removing the need for VIRT_ADDRESS_VARIES.
5156 (PURE_P): Use a more-efficient implementation that needs just one

5163 consistency with the new puresize.h.
5164 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

5172 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
5173 behave as if the cursor position were at the window margin.
5175 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
5176 and the cursor position is out of bounds, behave as if the cursor
5177 position were at the window margin. (Bug#10075)
5179 2011-11-18 Chong Yidong <cyd@gnu.org>
5181 * window.c (Fwindow_combination_limit): Make first argument

5202 * xdisp.c (row_hash): New function, body extracted from
5203 compute_line_metrics.
5204 (compute_line_metrics): Call row_hash, instead of computing the
5205 hash code inline.
5207 * dispnew.c (verify_row_hash): Call row_hash for computing the
5208 hash code of a row, instead of duplicating code from xdisp.c.
5210 * dispextern.h (row_hash): Add prototype.
5212 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
5214 * frame.c (delete_frame): Don't delete the terminal when the last

5250 * xdisp.c (display_line): Move the call to
5251 highlight_trailing_whitespace before the call to

5256 2011-11-14 Juanma Barranquero <lekktu@gmail.com>

5263 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
5264 with user-defined heap size. Bump the default size of the temacs
5265 heap to 27MB, to avoid memory warning when running temacs.
5266 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
5268 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

5387 * xmenu.c (cleanup_widget_value_tree): New function.
5388 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

5395 (window_box_width, window_box_left, window_box_left_offset)
5396 (window_box_right, window_box_right_offset): Declare extern.
5397 Otherwise, these inline functions do not conform to C99 and
5398 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
5399 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
5400 * intervals.c (adjust_intervals_for_insertion)

5403 (static_offset_intervals): Remove.
5404 (offset_intervals): Rewrite using the old contents of
5405 static_offset_intervals. The old version didn't conform to C99

5719 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
5720 * editfns.c: Rewrite current-time-zone so that it invokes
5721 the equivalent of (format-time-string "%Z") to get the time zone name.
5722 This fixes a bug when the time zone name contains characters that
5723 need converting from the system time locale to Emacs internal format.
5724 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
5725 that patch fixed format-time-string to do the conversion, but
5726 I forgot to fix current-time-zone.
5727 (format_time_string): New function, containing most of
5728 what Fformat_time_string used to contain.
5729 (Fformat_time_string): Rewrite in terms of format_time_string.

5733 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
5734 Jason Rumney's 2007-06-07 change worked around this bug, but
5735 didn't fix it.
5736 * systime.h (tzname, timezone): Remove no-longer-used declarations.
5738 2011-10-19 Eli Zaretskii <eliz@gnu.org>
5740 * xdisp.c (start_display): If the character at POS is displayed
5741 via a display vector, reset IT->current.dpvec_index to zero.
5742 (try_window_reusing_current_matrix): If a line ends in a display
5743 vector or the next line starts in a display vector, continue
5744 redrawing the window even though the character position of
5745 start_row was reached.
5746 (Bug#9771, part 2)
5748 2011-10-18 Chong Yidong <cyd@gnu.org>

5751 with nobreak-char-display too.
5753 2011-10-18 Eli Zaretskii <eliz@gnu.org>
5755 Fix part 3 of bug#9771.
5756 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
5757 (bidi_resolve_neutral): Don't enter the expensive loop looking for
5758 non-neutral characters if the current character is a paragraph
5759 separator (a.k.a. Newline). This avoids running the same
5760 expensive loop twice, once when we consume the preceding newline
5761 and the other time when the line actually needs to be displayed.
5762 Avoid the loop when we see neutrals on the base embedding level
5763 following a character whose directionality is the same as the
5764 paragraph's. This avoids running the expensive loop when a line
5765 ends in a long sequence of neutrals, like control characters.
5766 Add assertion against STRONG_AL type. Slightly rearrange code
5767 that determines the type of a neutral given the first non-neutral
5768 that follows it.
5769 (bidi_level_of_next_char): Set next_en_pos to zero when
5770 invalidating its info.
5772 2011-10-17 Eli Zaretskii <eliz@gnu.org>
5774 * xdisp.c (push_display_prop): Determine whether to record string
5775 or buffer position by IT->string, not by IT->method. Allow
5776 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
5777 (move_it_vertically_backward): Don't look for character position
5778 immediately after the newline when in a continuation line.
5779 (Bug#9771, part 1)
5781 2011-10-15 Martin Rudalics <rudalics@gmx.at>
5783 * window.c (coordinates_in_window): Rewrite and delabelize
5784 vertical border check. (Bug#5357) (Bug#9618)
5786 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
5788 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
5789 errors in XSetWindowBorder (bug#9310).
5791 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
5793 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
5794 avoid crash when xmalloc overrun checking is enabled.
5796 2011-10-13 Eli Zaretskii <eliz@gnu.org>
5798 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
5799 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
5800 cursor motion with <left> and <right> arrow keys.
5802 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
5803 some callers set that themselves.
5805 2011-10-12 Eli Zaretskii <eliz@gnu.org>
5807 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
5808 display string and the previous row comes from the same string and
5809 is empty. (Bug#9739) (Bug#9738)
5811 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
5813 * doc.c (get_doc_string): Encode file name (bug#9735).
5815 2011-10-12 Eli Zaretskii <eliz@gnu.org>
5817 * bidi.c (bidi_level_of_next_char):
5818 * xdisp.c (get_visually_first_element): Remove old incorrect
5819 comments regarding the Unicode Line Separator character.
5821 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
5823 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
5825 * alloc.c (Fgc_status): Do not access beyond zombies array
5826 boundary if nzombies > MAX_ZOMBIES.
5827 * alloc.c (dump_zombies): Add missing format specifier.
5829 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
5831 * xdisp.c (set_cursor_from_row): Simplify conditionals,
5832 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
5834 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
5835 Some packages use them to denote characters with modifiers.
5837 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
5839 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
5840 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
5841 matching a pp-number. Rename parameter var to var1.
5843 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
5845 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
5847 2011-10-08 Glenn Morris <rgm@gnu.org>
5849 * callint.c (Fcall_interactively): Give a more explicit error for the
5850 'c' case with a non-character input. (Bug#8479)
5852 2011-10-08 Eli Zaretskii <eliz@gnu.org>
5854 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
5855 lines.
5856 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
5857 lines that are hscrolled on the left.
5859 * dispnew.c (buffer_posn_from_coords): Account for a possible
5860 presence of header-line. (Bug#4426)
5862 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
5864 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
5865 Don't advertise functionality which we discourage or doesn't work.
5867 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
5869 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
5870 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
5871 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
5872 this makes Emacs dump core during garbage collection on rare
5873 occasions. sizeof is obviously inferior to offsetof here, so
5874 stick with offsetof.
5875 (GC_POINTER_ALIGNMENT): New macro.
5876 (mark_memory): Omit 3rd (offset) arg; caller changed.
5877 Don't assume EMACS_INT alignment is the same as pointer alignment.
5879 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
5881 * keyboard.c (read_key_sequence_remapped): New var.
5882 (read_key_sequence): Compute remapping in the right buffer.
5883 (command_loop_1): Use read_key_sequence's remapping directly.
5885 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5887 * dired.c (file_name_completion): Don't expand file name.
5888 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
5889 before checking file name handler.
5891 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
5892 they've been requested explicitly (bug#9591).
5894 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
5896 * keymap.c (Fsingle_key_description): Use make_specified_string
5897 instead of build_string to build string from push_key_description.
5898 (Bug#5193)
5900 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
5902 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
5903 This fixes a Y2038 bug on 64-bit hosts.
5904 * buffer.c (reset_buffer):
5905 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
5906 (Fclear_buffer_auto_save_failure):
5907 Use 0, not -1, to represent an unset failure time, since time_t
5908 might not be signed.
5910 Remove dependency on glibc malloc internals.
5911 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5912 Move back here from lisp.h, but with their new implementations.
5913 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5914 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
5915 * charset.c (charset_table_init): New static var.
5916 (syms_of_charset): Use it instead of xmalloc. This removes a
5917 dependency on glibc malloc internals. See Eli Zaretskii's comment in
5918 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
5919 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5920 Move back to alloc.c.
5921 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5922 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
5924 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
5926 * nsterm.m (windowDidResize): Call x_set_window_size only when
5927 ns_in_resize is true. Otherwise set pixelwidth/height and
5928 call change_frame_size (Bug#9628).
5930 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
5932 Port --enable-checking=all to Fedora 14 x86-64.
5933 * charset.c (syms_of_charset): Also account for glibc malloc's
5934 internal overhead when calculating the initial malloc maximum.
5936 Port --enable-checking=all to Fedora 14 x86.
5937 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5938 Move to lisp.h.
5939 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
5940 (overrun_check_realloc, overrun_check_free):
5941 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
5942 That way, xmalloc returns a properly-aligned pointer even if
5943 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
5944 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
5945 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
5946 into account when calculating the initial malloc maximum.
5947 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5948 Move here from alloc.c, so that charset.c can use it too.
5949 Properly align; the old code wasn't right for common 32-bit hosts
5950 when configured with --enable-checking=all.
5951 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5952 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
5954 2011-09-29 Eli Zaretskii <eliz@gnu.org>
5956 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
5957 use EDOM.
5959 2011-09-28 Eli Zaretskii <eliz@gnu.org>
5961 * xdisp.c (compute_display_string_end): If there's no display
5962 string at CHARPOS, return -1.
5964 * bidi.c (bidi_fetch_char): When compute_display_string_end
5965 returns a negative value, treat the character as a normal
5966 character not covered by a display string. (Bug#9624)
5968 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
5970 * lread.c (Fread_from_string): Fix typo in docstring.
5972 2011-09-27 Eli Zaretskii <eliz@gnu.org>
5974 * xdisp.c (handle_invisible_prop): If invisible text ends on a
5975 newline, reseat the iterator instead of bidi-iterating there one
5976 character at a time. (Bug#9610)
5977 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
5978 TO_CHARPOS if the bidi iterator is at base embedding level.
5980 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
5982 * lread.c (readevalloop): Use correct code for NBSP.
5983 (read1): Likewise. (Bug#9608)
5985 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
5987 * dbusbind.c (Fdbus_register_signal): When service is not
5988 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
5990 2011-09-25 Glenn Morris <rgm@gnu.org>
5992 * buffer.c (truncate-lines): Doc fix.
5994 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
5996 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
5997 (Fset_window_next_buffers): Doc fix.
5999 2011-09-24 Glenn Morris <rgm@gnu.org>
6001 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
6003 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
6005 Fix minor problems found by static checking.
6006 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
6007 * indent.c (Fvertical_motion): Fix == vs = typo.
6009 2011-09-24 Eli Zaretskii <eliz@gnu.org>
6011 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
6012 Default value is now t. Doc fix.
6014 * indent.c (Fvertical_motion): Compute and apply the overshoot
6015 logic when moving up, not only when moving down. Fix the
6016 confusing name and values of the it_overshoot_expected variable;
6017 logic changes accordingly. (Bug#9254) (Bug#9549)
6019 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
6020 CHARPOS is covered by a display string which includes newlines.
6021 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
6022 is covered by a display string with embedded newlines.
6024 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
6026 * dbusbind.c (Fdbus_register_signal): Add match rule to
6027 Vdbus_registered_objects_table. (Bug#9581)
6028 (Fdbus_register_method, Vdbus_registered_objects_table):
6029 Fix docstring.
6031 2011-09-24 Jim Meyering <meyering@redhat.com>
6033 do not ignore write error for any output size
6034 The previous change was incomplete.
6035 While it makes emacs --batch detect the vast majority of stdout
6036 write failures, errors were still ignored whenever the output size is
6037 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
6038 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
6039 && echo FAIL: ignored write error
6040 FAIL: ignored write error
6041 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
6042 && echo FAIL: ignored write error
6043 FAIL: ignored write error
6044 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
6046 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
6048 * emacs.c (Fkill_emacs): In noninteractive mode exit
6049 non-successfully if a write error occurred on stdout. (Bug#9574)
6051 2011-09-21 Eli Zaretskii <eliz@gnu.org>
6053 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
6054 the xassert test.
6056 * dispextern.h (struct it): Update the comment documenting what
6057 can it->OBJECT be.
6059 2011-09-20 Eli Zaretskii <eliz@gnu.org>
6061 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
6062 a display string, extend search for cursor position to end of row.
6063 (find_row_edges): If the row ends in a newline from a display
6064 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
6065 Handle the case of a display string with multiple newlines.
6066 (Fcurrent_bidi_paragraph_direction): Fix search for previous
6067 non-empty line. Fixes confusing cursor motion with arrow keys at
6068 the beginning of a line that starts with whitespace.
6070 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
6072 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
6073 (bug#9493).
6075 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
6077 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
6078 boolean (Bug#9154).
6080 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6082 * xdisp.c (display_line): Record maximum and minimum buffer
6083 positions even if no glyphs were produced (e.g., by a zero-width
6084 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
6085 buffer positions that will be removed from the glyph row because
6086 they don't fit.
6087 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
6088 column is beyond frame width: don't subtract 1 "pixel" when
6089 computing width of the stretch.
6090 (reseat_at_next_visible_line_start): Undo the change made on
6091 2011-09-17 that saved paragraph information and restored it after
6092 the call to `reseat'. (Bug#9545)
6094 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6096 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
6097 and turn window cursor on if cleared (Bug#9415).
6099 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
6101 * search.c (boyer_moore): Take unibyte characters from pattern
6102 literally. (Bug#9458)
6104 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6106 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
6108 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
6110 Fix minor problem found by static checking.
6111 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
6112 initialized, to pacify gcc -Wuninitialized.
6114 * fileio.c: Report proper errno when syscall falls.
6115 (Finsert_file_contents): Save and restore errno,
6116 so that report_file_error outputs the correct diagnostic.
6117 (Fwrite_region) [CLASH_DETECTION]: Likewise.
6119 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6121 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
6123 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6125 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
6126 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
6128 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6130 * xdisp.c (reseat_at_next_visible_line_start): Keep information
6131 about the current paragraph and restore it after the call to reseat.
6133 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
6134 (bidi_find_paragraph_start): Search back for paragraph beginning
6135 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
6136 (bidi_move_to_visually_next): Only trigger paragraph-related
6137 computations when the last character is a newline or at EOB, not
6138 just any NEUTRAL_B. (Bug#9470)
6140 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
6141 truncated lines if point is covered by a display string. (Bug#9524)
6143 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
6145 * xselect.c: Relax test for outgoing X longs (Bug#9498).
6146 (cons_to_x_long): New function.
6147 (lisp_data_to_selection_data): Use it. Correct the test for
6148 short-versus-long data; it was negated. Break out of vector
6149 loop, for efficiency, when a long datum is discovered.
6151 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
6153 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
6155 2011-09-16 Eli Zaretskii <eliz@gnu.org>
6157 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
6158 GCC PR/17406) by declaring this function with external scope.
6160 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6162 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
6163 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
6165 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
6167 * editfns.c (Fformat): Correctly handle text properties on "%%".
6169 2011-09-15 Eli Zaretskii <eliz@gnu.org>
6171 * xterm.c (x_draw_composite_glyph_string_foreground):
6172 * w32term.c (x_draw_composite_glyph_string_foreground):
6173 * term.c (encode_terminal_code):
6174 * composite.c (composition_update_it, get_composition_id):
6175 * xdisp.c (get_next_display_element)
6176 (fill_composite_glyph_string): Add comments about special meaning
6177 of TAB characters in a composition.
6179 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6181 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
6182 This occurs when processing a multibyte format.
6183 Problem reported by Wolfgang Jenker.
6185 2011-09-15 Johan Bockgård <bojohan@gnu.org>
6187 * xdisp.c (try_cursor_movement): Only check for exact match if
6188 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
6190 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6192 Remove unused external symbols.
6193 * dispextern.h (calc_pixel_width_or_height): Remove decl.
6194 * xdisp.c (calc_pixel_width_or_height): Now static.
6195 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
6196 * indent.c (check_display_width):
6197 * w32term.c: Fix comment to match code.
6198 * xterm.c, xterm.h (x_catching_errors): Remove.
6200 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6202 * xselect.c: Use signed conversions more consistently (Bug#9498).
6203 (selection_data_to_lisp_data): Assume incoming selection data are
6204 signed integers, not unsigned. This is to be consistent with
6205 outgoing selection data, which was modified to use signed integers
6206 in as part of the fix to Bug#9196 in response to Jan D.'s comment
6207 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
6208 expects long, not unsigned long.
6210 2011-09-14 Eli Zaretskii <eliz@gnu.org>
6212 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
6213 computation of loop end. Reported by Johan Bockgård
6214 <bojohan@gnu.org>.
6216 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
6218 * frame.c (Fother_visible_frames_p): Function deleted.
6220 2011-09-12 Eli Zaretskii <eliz@gnu.org>
6222 * indent.c (compute_motion): Process display vector front to back
6223 rather than the other way around. (Bug#2496)
6225 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6227 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
6229 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
6231 * minibuf.c (Fread_from_minibuffer): Doc fix.
6233 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6235 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
6236 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
6238 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
6240 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
6241 value for non-existent files.
6243 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6245 * fileio.c (Finsert_file_contents): If the file cannot be opened,
6246 set its "size" to -1. This will set the modtime_size field of
6247 the corresponding buffer to -1, which is what
6248 verify-visited-file-modtime expects for files that do not exist.
6249 (Bug#9139)
6251 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
6253 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
6254 here ...
6255 * lisp.h: ... from here. push_key_description is no longer
6256 defined in keyboard.c, so its declaration should not be in
6257 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
6258 logically belongs with push_key_description.
6260 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
6262 * buffer.h: Include <sys/types.h> instead of <time.h>.
6263 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
6264 Problem reported by Herbert J. Skuhra.
6266 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
6268 * xml.c (parse_region): Make the parsing work for
6269 non-comment-starting XML files again (bug#9144).
6271 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
6273 * image.c (gif_load): Fix calculation of bottom and right corner.
6274 (Bug#9468)
6276 2011-09-10 Eli Zaretskii <eliz@gnu.org>
6278 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
6279 redisplay in small windows.
6281 2011-09-09 Eli Zaretskii <eliz@gnu.org>
6283 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
6285 2011-09-08 Martin Rudalics <rudalics@gmx.at>
6287 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
6288 Operate on live windows only.
6290 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
6292 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
6294 2011-09-07 Eli Zaretskii <eliz@gnu.org>
6296 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
6297 only under bidi iteration.
6299 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
6301 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
6303 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6305 isnan: Fix porting problem to Solaris 10 with bundled gcc.
6306 Without this fix, the command to link temacs failed due to an
6307 undefined symbol __builtin_isnan. This is because
6308 /usr/include/iso/math_c99.h #defines isnan(x) to
6309 __builtin_isnan(x), but the bundled gcc, which identifies itself
6310 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
6311 a __builtin_isnan.
6312 * floatfns.c (isnan): #undef, and then #define to a clone of
6313 what's in data.c.
6314 (Fisnan): Always define, since it's always available now.
6315 (syms_of_floatfns): Always define isnan at the Lisp level.
6317 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6319 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
6321 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6323 * fileio.c: Fix bugs with large file offsets (Bug#9428).
6324 The previous code assumed that file offsets (off_t values) fit in
6325 EMACS_INT variables, which is not true on typical 32-bit hosts.
6326 The code messed up by falsely reporting buffer overflow in cases
6327 such as (insert-file-contents "big" nil 1 2) into an empty buffer
6328 when "big" contains more than 2**29 bytes, even though this
6329 inserts just one byte and does not overflow the buffer.
6330 (Finsert_file_contents): Store file offsets as off_t
6331 values, not as EMACS_INT values. Check for overflow when
6332 converting between EMACS_INT and off_t. When checking for
6333 buffer overflow or for overlap, take the offsets into account.
6334 Don't use EMACS_INT for small values where int suffices.
6335 When checking for overlap, fix a typo: ZV was used where
6336 ZV_BYTE was intended.
6337 (Fwrite_region): Don't assume off_t fits into 'long'.
6338 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
6340 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
6342 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
6344 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6346 sprintf-related integer and memory overflow issues (Bug#9412).
6348 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
6349 (esprintf, exprintf, evxprintf): New functions.
6350 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
6351 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
6352 (modify_event_symbol): Do not assume that the length of
6353 name_alist_or_stem is safe to alloca and fits in int.
6354 (Fexecute_extended_command): Likewise for function name and binding.
6355 (Frecursion_depth): Wrap around reliably on integer overflow.
6356 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
6357 since some callers pass EMACS_INT values.
6358 (Fsingle_key_description): Don't crash if symbol name contains more
6359 than MAX_ALLOCA bytes.
6360 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
6361 (get_minibuffer): Arg is now EMACS_INT, not int.
6362 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
6363 (esprintf, exprintf, evxprintf): New decls.
6364 * window.h (command_loop_level, minibuf_level): Reflect API changes.
6366 * dbusbind.c (signature_cat): New function.
6367 (xd_signature, Fdbus_register_signal):
6368 Do not overrun buffer; instead, report string overflow.
6370 * dispnew.c (add_window_display_history): Don't overrun buffer.
6371 Truncate instead; this is OK since it's just a log.
6373 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
6374 even if the time zone offset is outlandishly large.
6375 Don't mishandle offset == INT_MIN.
6377 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
6378 when creating daemon; the previous buffer-overflow check was incorrect.
6380 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
6381 which has the guts of the old verror function.
6383 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
6384 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
6386 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
6387 (font_unparse_xlfd): Don't blindly alloca long strings.
6388 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
6389 fits in int, when using sprintf. Use single snprintf to count
6390 length of string rather than counting it via multiple sprintfs;
6391 that's simpler and more reliable.
6392 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
6393 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
6394 sprintf, in case result does not fit in int.
6396 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
6397 (fontset_from_font): Print it.
6399 * frame.c (tty_frame_count): Now printmax_t, not int.
6400 (make_terminal_frame, set_term_frame_name): Print it.
6401 (x_report_frame_params): In X, window IDs are unsigned long,
6402 not signed long, so print them as unsigned.
6403 (validate_x_resource_name): Check for implausibly long names,
6404 and don't assume name length fits in 'int'.
6405 (x_get_resource_string): Don't blindly alloca invocation name;
6406 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
6407 not fit in int.
6409 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
6410 (xg_check_special_colors, xg_set_geometry):
6411 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
6413 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
6414 Use esprintf, not sprintf, in case result does not fit in int.
6416 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6417 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
6418 it as a large positive number.
6419 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
6420 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6422 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
6423 in case result does not fit in int.
6425 * print.c (float_to_string): Detect width overflow more reliably.
6426 (print_object): Make sprintf buffer a bit bigger, to avoid potential
6427 buffer overrun. Don't assume list length fits in 'int'. Treat
6428 print length of 0 as 0, not as infinity; to be consistent with other
6429 uses of print length in this function. Don't overflow print length
6430 index. Don't assume hash table size fits in 'long', or that
6431 vectorlike size fits in 'unsigned long'.
6433 * process.c (make_process): Use printmax_t, not int, to format
6434 process-name gensyms.
6436 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
6438 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
6439 to avoid potential buffer overrun.
6441 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
6442 if X resource line is longer than 512 bytes.
6444 * xfns.c (x_window): Make sprintf buffer a bit bigger
6445 to avoid potential buffer overrun.
6447 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
6449 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
6451 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6453 Integer overflow fixes for scrolling, etc.
6454 Without these, Emacs silently mishandles large integers sometimes.
6455 For example, "C-u 4294967297 M-x recenter" was treated as if
6456 it were "C-u 1 M-x recenter" on a typical 64-bit host.
6458 * xdisp.c (try_window_id): Check Emacs fixnum range before
6459 converting to 'int'.
6461 * window.c (window_scroll_line_based, Frecenter):
6462 Check that an Emacs fixnum is in range before assigning it to 'int'.
6463 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
6464 values converted from Emacs fixnums.
6465 (Frecenter): Don't wrap around a line count if it is out of 'int'
6466 range; instead, treat it as an extreme value.
6467 (Fset_window_configuration, compare_window_configurations):
6468 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
6470 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
6471 that can exceed INT_MAX. Check that EMACS_INT value is in range
6472 before assigning it to the (possibly-narrower) index.
6473 (match_limit): Don't assume that a fixnum can fit in 'int'.
6475 * print.c (print_object): Use ptrdiff_t, not int, for index that can
6476 exceed INT_MAX.
6478 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
6479 (Fvertical_motion): Don't wrap around LINES values that don't fit
6480 in 'int'. Instead, treat them as extreme values. This is good
6481 enough for windows, which can't have more than INT_MAX lines anyway.
6483 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
6485 * Require libxml/parser.h to avoid compilation warning.
6487 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
6489 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
6490 since this reportedly can destroy thread storage.
6492 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
6494 * syntax.c (find_defun_start): Update all cache variables if
6495 exiting early (Bug#9401).
6497 2011-08-30 Eli Zaretskii <eliz@gnu.org>
6499 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
6501 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
6502 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
6503 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
6505 * term.c (tty_append_glyph): New function.
6506 (produce_stretch_glyph): Static function and its prototype deleted.
6508 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
6509 Add prototypes.
6511 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
6513 * image.c (parse_image_spec): Check for nonnegative, not for positive,
6514 when checking :margin (Bug#9390).
6515 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
6516 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
6517 so that the name doesn't mislead. All uses changed.
6519 2011-08-28 Johan Bockgård <bojohan@gnu.org>
6521 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
6522 set_tty_hooks.
6524 2011-08-27 Eli Zaretskii <eliz@gnu.org>
6526 * xdisp.c (move_it_to): Don't bail out early when reaching
6527 position beyond to_charpos, if we are scanning backwards.
6528 (move_it_vertically_backward): When DY == 0, make sure we get to
6529 the first character in the line after the newline.
6531 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
6533 * ccl.c: Improve and simplify overflow checking (Bug#9196).
6534 (ccl_driver): Do not generate an out-of-range pointer.
6535 (Fccl_execute_on_string): Remove unnecessary check for
6536 integer overflow, noted by Stefan Monnier in
6537 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
6538 Remove a FIXME that didn't need fixing.
6539 Simplify the newly-introduced buffer reallocation code.
6541 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
6543 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
6545 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
6547 Integer and memory overflow issues (Bug#9196).
6549 * doc.c (get_doc_string): Rework so that
6550 get_doc_string_buffer_size is the actual buffer size, rather than
6551 being 1 less than the actual buffer size; this makes xpalloc more
6552 convenient.
6554 * image.c (x_allocate_bitmap_record, cache_image):
6555 * xselect.c (Fx_register_dnd_atom):
6556 Simplify previous changes by using xpalloc.
6558 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
6559 since either will do and ptrdiff_t is convenient with xpalloc.
6561 * charset.c (charset_table_size)
6562 (struct charset_sort_data.priority): Now ptrdiff_t.
6563 (charset_compare): Don't overflow if priorities differ greatly.
6564 (Fsort_charsets): Don't assume list length fits in int.
6565 Check for size-calculation overflow when allocating sort data.
6566 (syms_of_charset): Allocate an initial charset table that is
6567 just under 64 KiB, to avoid problems with glibc malloc and mmap.
6569 * cmds.c (internal_self_insert): Check for size-calculation overflow.
6571 * composite.h (struct composition.glyph_len): Now int, not unsigned.
6572 The actual value is always <= INT_MAX, and leaving it unsigned made
6573 overflow checking harder.
6575 * dispextern.h (struct glyph_matrix.rows_allocated)
6576 (struct face_cache.size): Now ptrdiff_t, for convenience in use
6577 with xpalloc. The values are still always <= INT_MAX.
6579 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
6581 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
6582 (SAFE_NALLOCA): New macro.
6584 * region-cache.c (struct boundary.pos, find_cache_boundary)
6585 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
6586 (set_cache_region, invalidate_region_cache)
6587 (revalidate_region_cache, know_region_cache, region_cache_forward)
6588 (region_cache_backward, pp_cache):
6589 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
6590 so that ptrdiff_t * can be passed to xpalloc.
6591 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
6592 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
6593 (pp_cache): Don't assume cache_len fits in int.
6594 * region-cache.h: Adjust extern decls to match.
6596 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
6597 EMACS_INT, since either will do, for xpalloc.
6599 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
6600 (xnmalloc, xnrealloc, xpalloc): New functions.
6602 * bidi.c (bidi_shelve_header_size): New constant.
6603 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
6604 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
6606 * bidi.c (bidi_cache_shrink):
6607 * buffer.c (overlays_at, overlays_in, record_overlay_string)
6608 (overlay_strings):
6609 Don't update size of array until after memory allocation succeeds,
6610 because xmalloc/xrealloc may not return.
6611 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
6612 now that we have proper integer overflow checking.
6613 (record_overlay_string, overlay_strings): Catch overflows when
6614 calculating size of overlay_str_buf.
6616 * callproc.c (Fcall_process): Check for size overflow when
6617 calculating size of args2.
6618 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
6619 Normally we prefer signed values, but sticking with ptrdiff_t would
6620 require adding more-complicated checks.
6622 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
6623 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
6624 Redo buffer-overflow calculations to avoid integer overflow.
6625 Add a FIXME comment where memory seems to be over-allocated.
6627 * character.c (Fstring): Check for size-calculation overflow.
6629 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
6630 unnecessary integer overflow. Check for size overflow.
6631 (encode_coding_object): Don't update size until xmalloc succeeds.
6633 * composite.c (get_composition_id): Check for overflow in glyph
6634 length calculations.
6636 Integer and memory overflow fixes for display code.
6637 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
6638 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
6639 (scrolling_window): Check for overflow in size calculations.
6640 (line_draw_cost, realloc_glyph_pool, add_row_entry):
6641 Don't assume glyph table len fits in int.
6642 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
6643 (row_table_size): Now ptrdiff_t, not int.
6644 (scrolling_window): Avoid overflow in size calculations.
6645 Don't update size until allocation succeeds.
6646 * fns.c (concat): Check for overflow in size calculations.
6647 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
6648 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
6649 (NEXT_ALMOST_PRIME_LIMIT): New constant.
6651 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
6652 (get_doc_string): Check for size calculation overflow.
6653 Don't update size until allocation succeeds.
6654 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
6655 EMACS_INT, where ptrdiff_t will do.
6656 (Fsubstitute_command_keys): Check for string overflow.
6658 * editfns.c (set_time_zone_rule): Don't assume environment length
6659 fits in int.
6660 (message_length): Now ptrdiff_t, not int.
6661 (Fmessage_box): Don't update size until allocation succeeds.
6662 Don't assume message length fits in int.
6663 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
6665 * emacs.c (main): Do not reallocate argv, since there is a null at
6666 the end that can be overwritten, and this way there's no need to
6667 worry about size-calculation overflow.
6668 (sort_args): Check for size-calculation overflow.
6670 * eval.c (init_eval_once, grow_specpdl): Don't update size until
6671 alloc succeeds.
6672 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
6674 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
6675 (x_set_scroll_bar_width, x_figure_window_size):
6676 Check for integer overflow.
6677 (x_set_alpha): Do not assume XINT fits in int.
6679 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
6680 This is for the members text_lines, text_cols, total_lines, total_cols,

6690 Check for size-calculation overflow.
6691 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
6692 do, as we prefer signed integers.

6746 (Fset_match_data): Don't assume list lengths fit in 'int'.
6748 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,

6780 Check for size calculation overflow.
6781 (cache_face): Treat size calculation overflows as if they were

6784 * xfns.c (x_encode_text, x_set_name_internal)
6785 (Fx_change_window_property): Use ptrdiff_t, not int, to count
6786 sizes, since they can exceed INT_MAX in size. Check for size

6796 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
6797 (X_LONG_MIN): New macros.
6798 Use them to make the following changes clearer.
6799 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
6800 This change doesn't affect the value now, but it may help remind
6801 future maintainers not to raise the value too much later.
6802 (SELECTION_QUANTUM): Remove, replacing with ...
6803 (selection_quantum): ... new function, which avoids overflow.
6804 All uses changed.
6805 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
6806 assumption that selection length fits in 'int'.

6823 Don't store size until memory allocation succeeds.
6824 (x_get_window_property): Plug memory leak on memory exhaustion.
6825 Don't double-block input; malloc is safe here. Don't assume 2**34
6826 - 4 fits in unsigned long. Add an xassert to check
6827 XGetWindowProperty overflow. Be more careful about overflow
6828 calculations, and distinguish size from memory overflow better.

6834 in the range -65535 through -1 fit in an X unsigned short.
6835 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
6836 result parameters unless successful. Rely on cons_to_unsigned
6837 to report problems with elements; the old code wasn't right anyway.
6838 (x_check_property_data): Check for int overflow; we cannot use
6839 a wider type due to X limits.

6872 * lisp.h (hash_lookup, hash_put):
6873 * minibuf.c (Ftest_completion):
6874 Use ptrdiff_t for hash table indexes, not int (which is too
6875 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
6876 32-bit --with-wide-int hosts).
6878 * charset.c (Fdefine_charset_internal): Check for integer overflow.
6879 Add a FIXME comment about memory leaks.

6884 * character.h (CHAR_WIDTH):
6885 * indent.c (MULTIBYTE_BYTES_WIDTH):
6886 Use sanitize_char_width to avoid undefined and/or bad behavior
6887 with outlandish widths.
6888 * character.h (sanitize_tab_width): Rename from sanitize_width,
6889 now that we have two such functions. All uses changed.
6890 (sanitize_char_width): New inline function.

6910 exceed limits imposed by XClientMessageEvent, as well as the usual
6911 ptrdiff_t and size_t limits.
6913 * keyboard.c: Overflow, signedness and related fixes.
6914 (make_lispy_movement): Use same integer type in forward decl
6915 that is used in the definition.
6916 (read_key_sequence, keyremap_step):
6917 Change bufsize argument back to int, undoing my 2011-03-30 change.
6918 We prefer signed types, and int is wide enough here.
6919 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
6920 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
6921 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
6922 length, not size_t. Use ptrdiff_t for index, not int.
6923 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
6924 possibility of integer overflow.
6926 Overflow, signedness and related fixes for images.

6947 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
6948 (lookup_image): Remove unnecessary tests.
6949 (xbm_image_p): Locals are now of int, not EMACS_INT,
6950 since parse_image_check makes sure they fit into int.
6951 (png_load, gif_load, svg_load_image):
6952 Prefer int to unsigned where either will do.
6953 (tiff_handler): New function, combining the cores of the
6954 old tiff_error_handler and tiff_warning_handler.
6955 This function is rewritten to use vsnprintf and thereby avoid
6956 stack buffer overflows. It uses only the features of vsnprintf
6957 that are common to both POSIX and native Microsoft.
6958 (tiff_error_handler, tiff_warning_handler): Use it.
6959 (tiff_load, gif_load, imagemagick_load_image):
6960 Don't assume :index value fits in 'int'.
6961 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
6962 (imagemagick_load_image): Check that crop parameters fit into
6963 the integer types that MagickCropImage accepts. Don't assume
6964 Vimagemagick_render_type has a nonnegative value. Don't assume
6965 size_t fits in 'long'.
6966 (gs_load): Use printmax_t to print the widest integers possible.

6979 handle_single_display_spec, not just 1 or zero.
6980 (handle_single_display_spec): If the display spec is of the form
6981 `(space ...)', and specifies display in the text area, return 2
6982 rather than 1.
6983 (try_cursor_movement): Check for the need to scroll more
6984 accurately, and prefer exact match for point under bidi.
6985 Don't advance `row' beyond the last row of the window.
6987 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
6988 into disp_prop; all users changed.

7003 buffers, return left-to-right.
7004 (set_cursor_from_row): Consider candidate row a win if its glyph
7005 represents a newline and point is on that newline. Fixes cursor
7006 positioning on the newline at EOL of R2L text within L2R
7007 paragraph, and vice versa.
7008 (try_cursor_movement): Check continued rows, in addition to
7009 continuation rows. Fixes unwarranted scroll when point enters a
7010 continued line of R2L text within an L2R paragraph, or vice versa.
7011 (cursor_row_p): Consider the case of point being equal to
7012 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
7013 from the end of a short line to the beginning of a continued line
7014 of R2L text within L2R paragraph.
7015 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

7039 account for the height of the header line. (Bug#8874)
7041 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
7042 instead of CHAR_TO_BYTE. Fixes a crash when a completion
7043 candidate is selected by the mouse, and that candidate has a
7044 composed character under the mouse.
7046 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
7047 coordinates reported by pos-visible-in-window-p for a composed

7054 2011-08-22 Eli Zaretskii <eliz@gnu.org>
7056 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
7057 consider it a hit if to_charpos is anywhere in the range of the
7058 composed buffer positions.
7060 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
7062 * image.c (gif_load): Don't assume that each subimage has the same
7063 dimensions as the base image. Handle disposal method that is
7064 "undefined" by the gif spec (Bug#9335).
7066 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
7068 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

7071 2011-08-19 Eli Zaretskii <eliz@gnu.org>
7073 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
7074 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
7075 from an Org mode buffer to a Speedbar frame.
7077 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
7078 a composition, take its buffer position from IT->cmp_it.charpos.
7079 Fixes cursor positioning at the beginning of a line that begins
7080 with a composed character.
7082 2011-08-18 Eli Zaretskii <eliz@gnu.org>
7084 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
7085 character bidirectional type, use STRONG_L instead. Fixes crashes
7086 in a buffer produced by `describe-categories'.
7088 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
7089 members before the level stack, so they would be saved and
7090 restored when copying iterator state. Fixes incorrect reordering
7091 around TABs covered by display properties.
7093 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
7095 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

7129 in the static heap.
7130 [CYGWIN] (special_realloc): New function.
7131 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
7132 requests to realloc storage in the static heap.
7134 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
7136 * bidi.c (bidi_initialize): Remove unused local.
7138 2011-08-15 Eli Zaretskii <eliz@gnu.org>
7140 * bidimirror.h:
7141 * biditype.h: Remove file.
7142 * makefile.w32-in ($(BLD)/bidi.$(O)):
7143 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
7145 * dispextern.h: Fix a typo in the comment to bidi_type_t.
7147 * chartab.c: Improve commentary for the uniprop_table API.
7149 * bidi.c (bidi_paragraph_init): Support zero value of
7150 bidi_ignore_explicit_marks_for_paragraph_level.
7151 (bidi_initialize): Use uniprop_table instead of including
7152 biditype.h and bidimirror.h.
7154 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
7155 coordinates of the iterator when restoring from ppos_it.
7156 (Bug#9296)
7158 2011-08-14 Kenichi Handa <handa@m17n.org>
7160 * process.c (create_process): Call setup_process_coding_systems
7161 after the pid of the process is set to -1 (Bug#8162).
7163 2011-08-14 Eli Zaretskii <eliz@gnu.org>
7165 * xdisp.c (move_it_in_display_line_to): Don't invoke
7166 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
7167 ppos_it. Fixes vertical cursor motion when line beginning is
7168 covered by an image. (Bug#9296)
7170 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
7172 * nsterm.h (ns_run_ascript): Declare.
7173 (NSAPP_DATA2_RUNASSCRIPT): Define.
7175 * nsfns.m (as_script, as_result, as_status): New static variables.
7176 (ns_run_ascript): New function.
7177 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
7178 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
7179 the event loop. Get status from as_status (Bug#7276).
7181 * nsterm.m (sendEvent): If event is NSApplicationDefined and
7182 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
7183 the event loop (Bug#7276).
7185 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
7187 * gnutls.c (QCgnutls_bootprop_priority)
7188 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
7189 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
7190 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
7191 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
7192 (QCgnutls_bootprop_verify_hostname_error)
7193 (QCgnutls_bootprop_callbacks_verify): Rename from
7194 Qgnutls_bootprop_..., all uses changed.
7196 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
7197 uses changed.
7199 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
7201 * xfaces.c (Qframe_set_background_mode): Now static.
7202 * dispextern.h (Qframe_set_background_mode): Remove decl.
7204 * process.c (Fnetwork_interface_info): Declare local only if needed.
7206 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
7208 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
7209 (Fnetwork_interface_list): Allocate in increments of bytes instead
7210 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
7211 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
7212 sockaddr.
7213 (struct ifflag_def): notrailers is smart on OSX.
7214 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
7215 Get hardware address with getifaddrs if available.
7217 2011-08-12 Eli Zaretskii <eliz@gnu.org>
7219 * xdisp.c (iterate_out_of_display_property): xassert that
7220 IT->position is set to within IT->object's boundaries. Break from
7221 the loop as soon as EOB is reached; avoids infloops in redisplay
7222 when IT->position is set up wrongly due to some bug.
7223 Set IT->current to match the bidi iterator unconditionally.
7224 (push_display_prop): Allow GET_FROM_STRING as IT->method on
7225 entry. Force push_it to save on the stack the current
7226 buffer/string position, to be restored by pop_it. Fix flags in
7227 the iterator structure wrt the object coming from a display
7228 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
7229 properties. (Bug#9284)
7231 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
7233 * fontset.c (fontset_get_font_group): Add proper type checks.
7234 (Bug#9172)
7236 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7238 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
7239 and LC_VERSION_MIN_MACOSX.
7240 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
7241 (dump_it) [LC_FUNCTION_STARTS]: Use it.
7243 2011-08-08 Eli Zaretskii <eliz@gnu.org>
7245 * xdisp.c (forward_to_next_line_start): Allow to use the
7246 no-display-properties-and-no-overlays under bidi display.
7247 Set disp_pos in the bidi iterator to avoid searches for display
7248 properties and overlays.
7250 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
7252 * editfns.c (Fset_time_zone_rule): Document relationship with the
7253 setenv function.
7255 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
7256 the font entity extracted from the cache (Bug#8109).
7258 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
7260 * composite.c (autocmp_chars): Don't reset point. That is done by
7261 restore_point_unwind (Bug#5984).
7263 2011-08-07 Juri Linkov <juri@jurta.org>
7265 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
7266 to show the arg `TIME' instead of `TIMEVAL'.
7268 2011-08-06 Eli Zaretskii <eliz@gnu.org>
7270 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
7271 display property strides EOL and includes a newline, as in
7272 longlines-mode. (Bug#9254)
7273 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
7274 word-wrap under bidirectional display. (Bug#9224)
7276 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
7277 is non-zero, even if the data buffer is NULL. Fixes a crash in
7278 vertical-motion with longlines-mode. (Bug#9254)
7280 2011-08-05 Eli Zaretskii <eliz@gnu.org>
7282 * bidi.c <bidi_cache_total_alloc>: Now static.
7283 (bidi_initialize): Initialize bidi_cache_total_alloc.
7285 * xdisp.c (display_line): Release buffer allocated for shelved bidi
7286 cache. (Bug#9221)
7288 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
7289 amount allocated this far in `bidi_cache_total_alloc'.
7290 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
7291 non-zero, only free the data buffer without restoring the cache
7292 contents. All callers changed.
7294 * dispextern.h (bidi_unshelve_cache): Update prototype.
7296 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
7297 (move_it_in_display_line, move_it_to)
7298 (move_it_vertically_backward, move_it_by_lines): Replace the call
7299 to xfree to an equivalent call to bidi_unshelve_cache.
7300 (move_it_in_display_line_to): Fix logic of returning
7301 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
7303 2011-08-05 Eli Zaretskii <eliz@gnu.org>
7305 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
7306 came from a string character with a `cursor' property. (Bug#9229)
7308 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
7310 * Makefile.in (LIB_PTHREAD): New variable.
7311 (LIBES): Add LIB_PTHREAD (Bug#9216).
7313 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
7314 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
7316 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
7318 * regex.c (re_iswctype): Remove some redundant boolean conversions.
7320 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
7322 * xterm.c (x_find_topmost_parent): New function.
7323 (x_set_frame_alpha): Find topmost parent window with
7324 x_find_topmost_parent and set the property there also (bug#9181).
7325 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
7327 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
7329 * callproc.c (Fcall_process): Avoid vfork clobbering
7330 the local vars buffer, coding_systems, current_dir.
7332 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
7334 * keymap.c (Fmake_composed_keymap): Move to subr.el.
7336 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
7338 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
7339 so that it is not optimized away.
7341 * xdisp.c (compute_display_string_pos): Remove unused local.
7343 2011-08-02 Eli Zaretskii <eliz@gnu.org>
7345 Fix slow cursor motion and scrolling in large buffers with
7346 selective display, like Org Mode buffers. (Bug#9218)
7348 * dispextern.h (struct bidi_it): New member disp_prop_p.
7350 * xdisp.c: Remove one-slot cache of display string positions.
7351 (compute_display_string_pos): Accept an additional argument
7352 DISP_PROP_P; callers changed. Scan at most 5K characters forward
7353 for a display string or property. If found, set DISP_PROP_P
7354 non-zero.
7356 * bidi.c (bidi_fetch_char): Accept an additional argument
7357 DISP_PROP_P, and pass it to compute_display_string_pos.
7358 Only handle text covered by a display string if DISP_PROP_P is returned
7359 non-zero. All callers of bidi_fetch_char changed.
7361 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
7363 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
7365 2010-12-03 Don March <don@ohspite.net>
7367 * keymap.c (Fdefine_key): Fix non-prefix key error message when
7368 last character M-[char] is translated to ESC [char] (bug#7541).
7370 2011-08-02 Kenichi Handa <handa@m17n.org>
7372 * lisp.h (uniprop_table): Extern it.
7374 * chartab.c (uniprop_table): Make it non-static.
7376 2011-08-01 Eli Zaretskii <eliz@gnu.org>
7378 * xdisp.c (forward_to_next_line_start): Accept additional argument
7379 BIDI_IT_PREV, and store into it the state of the bidi iterator had
7380 on the newline.
7381 (reseat_at_next_visible_line_start): Use the bidi iterator state
7382 returned by forward_to_next_line_start to restore the state of
7383 it->bidi_it after backing up to previous newline. (Bug#9212)
7385 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
7387 * regex.c (re_comp): Protoize.
7388 (re_exec): Fix return type.
7389 (regexec): Fix type of `ret'. (Bug#9203)
7391 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7393 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
7394 This is needed if max-image-size is a floating-point number.
7396 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
7398 * print.c (print_object): Print empty symbol as ##.
7400 * lread.c (read1): Read ## as empty symbol.
7402 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
7404 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
7405 setting frame foreground color (Bug#9175).
7406 (x_set_background_color): Likewise.
7408 * nsmenu.m (-setText): Size tooltip dimensions precisely to
7409 contents (Bug#9176).
7410 (EmacsTooltip -init): Remove bezels and add shadows to
7411 tooltip windows.
7413 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
7414 or scroll bar (Bug#8470).
7416 * nsfont.m (nsfont_open): Remove assignment to voffset and
7417 unnecessary vars hshink, expand, hd, full_height, min_height.
7418 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
7420 * nsterm.h (nsfont_info): Remove voffset field.
7422 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
7424 Implement strike-through and overline on NextStep (Bug#8863).
7426 * nsfont.m (nsfont_open): Use underline position provided by font,
7427 instead of hard-coded value of 2.
7428 (nsfont_draw): Call ns_draw_text_decoration instead.
7430 * nsterm.h: Add declaration for ns_draw_text_decoration.
7432 * nsterm.m (ns_draw_text_decoration): New function for drawing
7433 underline, overline, and strike-through.
7434 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
7435 ns_draw_text_decoration. Change treatment of cursor drawing to
7436 accommodate underlining, etc.
7438 2011-07-28 Eli Zaretskii <eliz@gnu.org>
7440 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
7441 default.
7443 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7445 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
7446 Without this fix, if a signal arrives just after memory fills up,
7447 'malloc' might be invoked reentrantly.
7449 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
7450 In other words, assume that every image size is allowed, on non-X
7451 hosts. This assumption is probably wrong, but it lets Emacs compile.
7453 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
7455 * regex.c (re_iswctype): Convert return values to boolean.
7457 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
7459 * xdisp.c (compute_display_string_pos): Don't use cached display
7460 string position if the buffer had its restriction changed.
7461 (Bug#9184)
7463 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7465 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
7467 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7469 Integer signedness and overflow and related fixes. (Bug#9079)
7471 * bidi.c: Integer size and overflow fixes.
7472 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
7473 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
7474 (bidi_cache_find_level_change, bidi_cache_ensure_space)
7475 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
7476 (bidi_find_other_level_edge):
7477 Use ptrdiff_t instead of EMACS_INT where either will do.
7478 This works better on 32-bit hosts configured --with-wide-int.
7479 (bidi_cache_ensure_space): Check for size-calculation overflow.
7480 Use % rather than repeated addition, for better worst-case speed.
7481 Don't set bidi_cache_size until after xrealloc returns, because it
7482 might not return.
7483 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
7484 (bidi_cache_ensure_space): Also check that the bidi cache size
7485 does not exceed that of the largest Lisp string or buffer. See Eli
7486 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
7488 * alloc.c (__malloc_size_t): Remove.
7489 All uses replaced by size_t. See Andreas Schwab's note
7490 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
7492 * image.c: Improve checking for integer overflow.
7493 (check_image_size): Assume that f is nonnull, since
7494 it is always nonnull in practice. This is one less thing to
7495 worry about when checking for integer overflow later.
7496 (x_check_image_size): New function, which checks for integer
7497 overflow issues inside X.
7498 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
7499 This removes the need for a memory_full check.
7500 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
7501 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
7502 (xbm_read_bitmap_data): Change locals back to 'int', since
7503 their values must fit in 'int'.
7504 (xpm_load_image, png_load, tiff_load):
7505 Invoke x_create_x_image_and_pixmap earlier,
7506 to avoid much needless work if the image is too large.
7507 (tiff_load): Treat overly large images as if
7508 x_create_x_image_and_pixmap failed, not as malloc failures.
7509 (gs_load): Use x_check_image_size.
7511 * gtkutil.c: Omit integer casts.
7512 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
7513 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
7515 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
7517 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
7518 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
7519 would wrongly return t on a 64-bit host.
7521 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
7522 The plain *_OVERFLOW macros run afoul of GCC bug 49705
7523 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
7524 and therefore cause GCC to emit a bogus diagnostic in some cases.
7526 * image.c: Integer signedness and overflow and related fixes.
7527 This is not an exhaustive set of fixes, but it's time to
7528 record what I've got.
7529 (lookup_pixel_color, check_image_size): Remove redundant decls.
7530 (check_image_size): Don't assume that arbitrary EMACS_INT values
7531 fit in 'int', or that arbitrary 'double' values fit in 'int'.
7532 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
7533 (tiff_load, imagemagick_load_image):
7534 Check for overflow in size calculations.
7535 (x_create_x_image_and_pixmap): Remove unnecessary test for
7536 xmalloc returning NULL; that can't happen.
7537 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
7538 (xpm_color_bucket): Use better integer hashing function.
7539 (xpm_cache_color): Don't possibly over-allocate memory.
7540 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
7541 (gif_memory_source):
7542 Use ptrdiff_t, not int or size_t, to record sizes.
7543 (png_load): Don't assume values greater than 2**31 fit in 'int'.
7544 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
7545 either works, as we prefer signed integers.
7546 (tiff_read_from_memory, tiff_write_from_memory):
7547 Return tsize_t, not size_t, since that's what the TIFF API wants.
7548 (tiff_read_from_memory): Don't fail simply because the read would
7549 go past EOF; instead, return a short read.
7550 (tiff_load): Omit no-longer-needed casts.
7551 (Fimagemagick_types): Don't assume size fits into 'int'.
7553 Improve hashing quality when configured --with-wide-int.
7554 * fns.c (hash_string): New function, taken from sxhash_string.
7555 Do not discard information about ASCII character case; this
7556 discarding is no longer needed.
7557 (sxhash-string): Use it. Change sig to match it. Caller changed.
7558 * lisp.h: Declare it.
7559 * lread.c (hash_string): Remove, since we now use fns.c's version.
7560 The fns.c version returns a wider integer if --with-wide-int is
7561 specified, so this should help the quality of the hashing a bit.
7563 * emacs.c: Integer overflow minor fix.
7564 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
7565 Define only if GNU_LINUX.
7566 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
7568 * dispnew.c: Integer signedness and overflow fixes.
7569 Remove unnecessary forward decls, that were a maintenance hassle.
7570 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
7571 All uses changed.
7572 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
7573 (scrolling_window): Use ptrdiff_t, not int, for byte count.
7574 (prepare_desired_row, line_draw_cost):
7575 Use int, not unsigned, where either works.
7576 (save_current_matrix, restore_current_matrix):
7577 Use ptrdiff_t, not size_t, where either works.
7578 (init_display): Check for overflow more accurately, and without
7579 relying on undefined behavior.
7581 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
7582 Remove, replacing with the new symbols in lisp.h. All uses changed.
7583 * fileio.c (make_temp_name):
7584 * filelock.c (lock_file_1, lock_file):
7585 * xdisp.c (message_dolog):
7586 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
7587 Use pMd etc. instead.
7588 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
7589 replacing the pWIDE etc. symbols removed from editfns.c.
7591 * keyboard.h (num_input_events): Now uintmax_t.
7592 This is (very slightly) less likely to mess up due to wraparound.
7593 All uses changed.
7595 * buffer.c: Integer signedness fixes.
7596 (alloc_buffer_text, enlarge_buffer_text):
7597 Use ptrdiff_t rather than size_t when either will do, as we prefer
7598 signed integers.
7600 * alloc.c: Integer signedness and overflow fixes.
7601 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
7602 (__malloc_size_t): Default to size_t, not to int.
7603 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
7604 (Fgarbage_collect, mark_object_loop_halt, mark_object):
7605 Prefer ptrdiff_t to size_t when either would do, as we prefer
7606 signed integers.
7607 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
7608 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
7609 Now const. Initialize with values that are in range even if char
7610 is signed.
7611 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
7612 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
7613 These functions do the right thing with sizes > 2**32.
7614 (check_depth): Now ptrdiff_t, not int.
7615 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
7616 Adjust to new way of storing sizes. Check for size overflow bugs
7617 in rest of code.
7618 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
7619 slightly wrong anyway, as it missed one instance of
7620 XMALLOC_OVERRUN_CHECK_OVERHEAD.
7621 (refill_memory_reserve): Omit needless cast to size_t.
7622 (mark_object_loop_halt): Mark as externally visible.
7624 * xselect.c: Integer signedness and overflow fixes.
7625 (Fx_register_dnd_atom, x_handle_dnd_message):
7626 Use ptrdiff_t, not size_t, since we prefer signed.
7627 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
7628 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
7629 x_dnd_atoms_size and x_dnd_atoms_length.
7631 * doprnt.c: Prefer signed to unsigned when either works.
7632 * eval.c (verror):
7633 * doprnt.c (doprnt):
7634 * lisp.h (doprnt):
7635 * xdisp.c (vmessage):
7636 Use ptrdiff_t, not size_t, when using or implementing doprnt,
7637 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
7638 prefer signed arithmetic to avoid comparison confusion.
7639 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
7640 but is a bit tricky.
7642 Assume freestanding C89 headers, string.h, stdlib.h.
7643 * data.c, doprnt.c, floatfns.c, print.c:
7644 Include float.h unconditionally.
7645 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
7646 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
7647 * regex.c: Likewise for stddef.h, string.h.
7648 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
7649 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
7650 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
7651 (STDC_HEADERS): Remove obsolete defines.
7652 * sysdep.c: Include limits.h unconditionally.
7654 Assume support for memcmp, memcpy, memmove, memset.
7655 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
7656 * regex.c (memcmp, memcpy):
7657 Remove; we assume C89 now.
7659 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
7660 (__malloc_safe_bcopy): Remove; no longer needed.
7662 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
7663 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
7664 well either way, and we prefer signed to unsigned.
7666 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
7668 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
7669 closes the connection while we're reading (bug#9182).
7671 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
7673 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
7674 are specified (Bug#9168).
7676 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
7678 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
7679 Found by GCC static checking and --with-wide-int on a 32-bit host.
7681 2011-07-25 Eli Zaretskii <eliz@gnu.org>
7683 * xdisp.c (compute_display_string_pos): Fix logic of caching
7684 previous display string position. Initialize cached_prev_pos to
7685 -1. Fixes slow-down at the beginning of a buffer.
7687 2011-07-24 Eli Zaretskii <eliz@gnu.org>
7689 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
7690 for attrs[LFACE_FONTSET_INDEX].
7692 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
7694 * xml.c (parse_region): Remove unused local
7695 that was recently introduced.
7697 2011-07-23 Eli Zaretskii <eliz@gnu.org>
7699 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
7700 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
7702 * xdisp.c (move_it_in_display_line_to): Record the best matching
7703 position for TO_CHARPOS while scanning the line, and restore it on
7704 exit if none of the characters scanned was an exact match.
7705 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
7706 when exact match is impossible due to invisible text, and the
7707 lines are truncated.
7709 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
7711 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
7712 for OSX >= 10.7.
7714 2011-07-22 Eli Zaretskii <eliz@gnu.org>
7716 Fix a significant slow-down of cursor motion with C-n, C-p,
7717 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
7718 auto-repeat under bidi redisplay in fontified buffers.
7719 * xdisp.c (compute_stop_pos_backwards): New function.
7720 (next_element_from_buffer): Call compute_stop_pos_backwards to
7721 find a suitable prev_stop when we find ourselves before
7722 base_level_stop.
7723 (reseat): Don't look for prev_stop, as that could mean a very long
7724 run.
7725 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
7726 <cached_disp_overlay_modiff>: Cache for last found display string
7727 position.
7728 (compute_display_string_pos): Return the cached position if asked
7729 about the same buffer in the same area of character positions, and
7730 the buffer wasn't changed since the time the display string
7731 position was cached.
7733 2011-07-22 Eli Zaretskii <eliz@gnu.org>
7735 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
7736 is an integer, which is important for empty lines. (Bug#9149)
7738 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
7740 * frame.c (Fmodify_frame_parameters): In tty case, update the
7741 default face if necessary (Bug#4238).
7743 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
7745 * editfns.c (Fstring_to_char): No need to explain what a character
7746 is in the docstring (Bug#6576).
7748 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
7750 * xml.c (parse_region): Make sure we always return a tree.
7752 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
7754 * xml.c (parse_region): If a document contains only comments,
7755 return that, too.
7757 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
7759 * xml.c (make_dom): Return comments, too.
7761 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
7763 Port to OpenBSD.
7764 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
7765 and the surrounding thread.
7766 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
7767 rather than fgets, and retry after EINTR. Otherwise, 'emacs
7768 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
7769 timer goes off.
7770 * s/openbsd.h (BROKEN_SIGIO): Define.
7771 * unexelf.c (unexec) [__OpenBSD__]:
7772 Don't update the .mdebug section of the Alpha COFF symbol table.
7774 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7776 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
7777 (bug#8460).
7779 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
7781 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
7782 This fixes some race conditions on the permissions of any newly
7783 created file.
7785 * alloc.c (valid_pointer_p): Use pipe, not open.
7786 This fixes some permissions issues when debugging.
7788 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
7789 If fchown fails to set both uid and gid, try to set just gid,
7790 as that is sometimes allowed. Adjust the file's mode to eliminate
7791 setuid or setgid bits that are inappropriate if fchown fails.
7793 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
7795 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
7796 to compare Lisp_Objects.
7797 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
7798 global_gnutls_log_level, don't mistake it for a Lisp_Object.
7799 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
7801 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
7803 * lread.c (read_integer): Unread even EOF character.
7804 (read1): Likewise. Properly record start position of symbol.
7806 * lread.c (read1): Read `#:' as empty uninterned symbol if no
7807 symbol character follows.
7809 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
7811 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
7812 This works around a problem with the previous change to Fcopy_file.
7813 Recent glibc declares fchown with __attribute__((warn_unused_result)),
7814 and without this change, GCC might complain about discarding
7815 fchown's return value.
7817 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
7819 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
7821 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
7823 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
7825 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
7827 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
7828 it's used from the C level.
7830 * process.c: Use the same condition for POLL_FOR_INPUT in both
7831 keyboard.c and process.c (bug#1858).
7833 2011-07-09 Lawrence Mitchell <wence@gmx.li>
7835 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
7836 (Fgnutls_boot): Use it.
7838 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
7840 * doc.c (Fsubstitute_command_keys): Revert last change.
7842 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
7844 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
7845 quotes the next character, and doesn't affect other longer
7846 sequences (bug#8935).
7848 * lread.c (syms_of_lread): Clarify that is isn't only
7849 `eval-buffer' and `eval-defun' that's affected by
7850 `lexical-binding' (bug#8460).
7852 2011-07-15 Eli Zaretskii <eliz@gnu.org>
7854 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
7855 bidi redisplay when a line includes both an image and is truncated.
7857 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
7859 Fix minor problems found by static checking.
7860 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
7861 (elsz): Now a signed constant, not a size_t var. We prefer signed
7862 types to unsigned, to avoid integer comparison confusion. Without
7863 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
7864 "cannot optimize loop, the loop counter may overflow", a symptom
7865 of the confusion.
7866 * indent.c (Fvertical_motion): Mark locals as initialized.
7867 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
7869 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
7871 * search.c (Fre_search_backward): Mention `case-fold-search' in
7872 all the re_search_* functions (bug#8138).
7874 * keyboard.c (Fopen_dribble_file): Document when the file is
7875 closed (bug#8056).
7877 2011-07-14 Eli Zaretskii <eliz@gnu.org>
7879 * bidi.c (bidi_dump_cached_states): Fix format of displaying
7880 bidi_cache_idx.
7882 Support bidi reordering of display and overlay strings.
7883 * xdisp.c (compute_display_string_pos)
7884 (compute_display_string_end): Accept additional argument STRING.
7885 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
7886 (reseat_to_string): Initialize bidi_it->string.s and
7887 bidi_it->string.schars.
7888 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
7889 NULL (avoids a crash in bidi_paragraph_init).
7890 Initialize itb.string.lstring.
7891 (init_iterator): Call bidi_init_it only of a valid
7892 buffer position was specified. Initialize paragraph_embedding to
7893 L2R.
7894 (reseat_to_string): Initialize the bidi iterator.
7895 (display_string): If we need to ignore text properties of
7896 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
7897 original value of -1 will not work with bidi.)
7898 (compute_display_string_pos): First arg is now struct
7899 `text_pos *'; all callers changed. Support display properties on
7900 Lisp strings.
7901 (compute_display_string_end): Support display properties on Lisp
7902 strings.
7903 (init_iterator, reseat_1, reseat_to_string): Initialize the
7904 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
7905 when iterating on a string not from display properties).
7906 (compute_display_string_pos, compute_display_string_end):
7907 Fix calculation of the object to scan. Fixes an error when using
7908 arrow keys.
7909 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
7910 base_level_stop; instead, set base_level_stop to BEGV.
7911 Fixes crashes in vertical-motion.
7912 (next_element_from_buffer): Improve commentary for when
7913 the iterator is before prev_stop.
7914 (init_iterator): Initialize bidi_p from the default value of
7915 bidi-display-reordering, not from buffer-local value. Use the
7916 buffer-local value only if initializing for buffer iteration.
7917 (handle_invisible_prop): Support invisible properties on strings
7918 that are being bidi-reordered.
7919 (set_iterator_to_next): Support bidi reordering of C strings and
7920 Lisp strings.
7921 (next_element_from_string): Support bidi reordering of Lisp
7922 strings.
7923 (handle_stop_backwards): Support Lisp strings as well.
7924 (display_string): Support display of R2L glyph rows.
7925 Use IT_STRING_CHARPOS when displaying from a Lisp string.
7926 (init_iterator): Don't initialize it->bidi_p for strings
7927 here.
7928 (reseat_to_string): Initialize it->bidi_p for strings here.
7929 (next_element_from_string, next_element_from_c_string)
7930 (next_element_from_buffer): Add xassert's for correspondence
7931 between IT's object being iterated and it->bidi_it.string
7932 structure.
7933 (face_before_or_after_it_pos): Support bidi iteration.
7934 (next_element_from_c_string): Handle the case of the first string
7935 character that is not the first one in the visual order.
7936 (get_visually_first_element): New function, refactored from common
7937 parts of next_element_from_buffer, next_element_from_string, and
7938 next_element_from_c_string.
7939 (tool_bar_lines_needed, redisplay_tool_bar)
7940 (display_menu_bar): Force left-to-right direction. Add a FIXME
7941 comment for making that be controlled by a user option.
7942 (push_it, pop_it): Save and restore the state of the
7943 bidi iterator. Save and restore the bidi_p flag.
7944 (pop_it): Iterate out of display property for string iteration as
7945 well.
7946 (iterate_out_of_display_property): Support iteration over strings.
7947 (handle_single_display_spec): Set up it->bidi_it for iteration
7948 over a display string, and call bidi_init_it.
7949 (handle_single_display_spec, next_overlay_string)
7950 (get_overlay_strings_1, push_display_prop): Set up the bidi
7951 iterator for displaying display or overlay strings.
7952 (forward_to_next_line_start): Don't use the shortcut if
7953 bidi-iterating.
7954 (back_to_previous_visible_line_start): If handle_display_prop
7955 pushed the iterator stack, restore the internal state of the bidi
7956 iterator by calling bidi_pop_it same number of times.
7957 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
7958 and we are bidi-iterating, don't decrement the iterator position;
7959 instead, set the first_elt flag in the bidi iterator, to produce
7960 the same effect.
7961 (reseat_1): Remove redundant setting of string_from_display_prop_p.
7962 (push_display_prop): xassert that we are iterating a buffer.
7963 (push_it, pop_it): Save and restore paragraph_embedding member.
7964 (handle_single_display_spec, next_overlay_string)
7965 (get_overlay_strings_1, reseat_1, reseat_to_string)
7966 (push_display_prop): Set up the `unibyte' member of bidi_it.string
7967 correctly. Don't assume unibyte strings are not bidi-reordered.
7968 (compute_display_string_pos)
7969 (compute_display_string_end): Fix handling the case of C string.
7970 (push_it, pop_it): Save and restore from_disp_prop_p.
7971 (handle_single_display_spec, push_display_prop): Set the
7972 from_disp_prop_p flag.
7973 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
7974 (pop_it): Call iterate_out_of_display_property only if we are
7975 popping after iteration over a string that came from a display
7976 property. Fix a typo in popping stretch info. Add an assertion
7977 for verifying that the iterator position is in sync with the bidi
7978 iterator.
7979 (handle_single_display_spec, get_overlay_strings_1)
7980 (push_display_prop): Fix initialization of paragraph direction for
7981 string when that of the parent object is not yet determined.
7982 (reseat_1): Call bidi_init_it to resync the bidi
7983 iterator with IT's position. (Bug#7616)
7984 (find_row_edges): If ROW->start.pos gives position
7985 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
7986 (handle_stop, back_to_previous_visible_line_start, reseat_1):
7987 Reset the from_disp_prop_p flag.
7988 (SAVE_IT, RESTORE_IT): New macros.
7989 (pos_visible_p, face_before_or_after_it_pos)
7990 (back_to_previous_visible_line_start)
7991 (move_it_in_display_line_to, move_it_in_display_line)
7992 (move_it_to, move_it_vertically_backward, move_it_by_lines)
7993 (try_scrolling, redisplay_window, display_line): Use them when
7994 saving a temporary copy of the iterator and restoring it back.
7995 (back_to_previous_visible_line_start, reseat_1)
7996 (init_iterator): Empty the bidi cache "stack".
7997 (move_it_in_display_line_to): If iterator ended up at
7998 EOL, but we never saw any buffer positions smaller than
7999 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
8000 motion in bidi-reordered lines.
8001 (move_it_in_display_line_to): Record prev_method and prev_pos
8002 immediately before the call to set_iterator_to_next. Fixes cursor
8003 motion in bidi-reordered lines with stretch glyphs and strings
8004 displayed in margins. (Bug#8133) (Bug#8867)
8005 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
8006 TO_CHARPOS.
8007 (pos_visible_p): Support positions in bidi-reordered lines.
8008 Save and restore bidi cache.
8010 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
8011 (bidi_paragraph_info): Delete unused struct.
8012 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
8013 (bidi_cache_start): New variable.
8014 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
8015 to zero.
8016 (bidi_cache_fetch_state, bidi_cache_search)
8017 (bidi_cache_find_level_change, bidi_cache_iterator_state)
8018 (bidi_cache_find, bidi_peek_at_next_level)
8019 (bidi_level_of_next_char, bidi_find_other_level_edge)
8020 (bidi_move_to_visually_next): Compare cache index with
8021 bidi_cache_start rather than with zero.
8022 (bidi_fetch_char): Accept new argument STRING; all callers

8119 Vx_lost_selection_functions to Frun_hook_with_args.
8121 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
8123 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
8124 The old code sometimes used this field without initializing it.
8126 * alloc.c (gc_sweep): Don't read past end of array.
8127 In theory, the old code could also have corrupted Emacs internals,

8132 * character.c (Fcharacterp): Don't advertise optional ignored

8391 (clone_per_buffer_values): Don't assume that
8392 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
8393 This isn't true in general, and it's particularly not true
8394 if Emacs is configured with --with-wide-int.
8395 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
8396 New macros, used in the buffer.c change.

8430 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
8432 Random fixes. E.g., (random) never returned negative values.
8433 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
8434 subseconds part to the entropy, as that's a bit more random.
8435 Prefer signed to unsigned, since the signedness doesn't matter and
8436 in general we prefer signed. When given a limit, use a
8437 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
8438 latter isn't right if USE_2_TAGS_FOR_INTS.
8439 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
8440 not 0..VALMASK. Don't discard "excess" bits that random () returns.

8450 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
8452 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
8453 This is more efficient than Ffile_directory_p and avoids a minor race.
8455 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
8457 * buffer.c (Foverlay_put): Say what the return value is
8458 (bug#7835).
8460 * fileio.c (barf_or_query_if_file_exists): Check first if the file
8461 is a directory before asking whether to use the file name
8462 (bug#7564).
8463 (barf_or_query_if_file_exists): Make the "File is a directory"
8464 error be more correct.
8466 * fns.c (Frequire): Remove the mention of the .gz files, since
8467 that's installation-specific, but keep the mention of

8585 * eval.c (struct backtrace): Simplify and port the data structure.
8586 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
8587 signed bit field, as this assumption is not portable and it makes
8588 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
8589 "char debug_on_exit : 1" as this is not portable either; instead,
8590 use the portable "unsigned int debug_on_exit : 1". Remove unused
8591 member evalargs. Remove obsolete comments about cc bombing out.
8593 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

8827 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
8828 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
8829 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
8830 since we're not interested in debugging glyphs with old libraries.
8831 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
8832 GCC 4.6.0's static checking.
8834 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

8874 (x_session_initialize): Do not assume string length fits in int.
8876 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.

8920 Invoke gzip -cd rather than gunzip, as it's more portable.
8921 (lock_info_type, lock_file_1, lock_file):
8922 Don't assume pid_t and time_t fit in unsigned long.
8923 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
8924 (current_lock_owner): Prefer signed type for sizes.
8925 Use memcpy, not strncpy, where memcpy is what is really wanted.
8926 Don't assume (via atoi) that time_t and pid_t fit in int.
8927 Check for time_t and/or pid_t out of range, e.g., via a network share.
8928 Don't alloca where an auto var works fine.
8930 * fileio.c: Fix some integer overflow issues.
8931 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
8932 Don't assume string length fits in int.
8933 (directory_file_name): Don't assume string length fits in long.
8934 (make_temp_name): Don't assume pid fits in int, or that its print
8935 length is less than 20.
8937 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
8939 * coding.c (make_subsidiaries): Don't assume string length fits in int.
8941 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
8943 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
8944 We prefer signed integers, even for size calculations.
8946 * emacs.c: Don't assume string length fits in 'int'.
8947 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
8948 (main): Don't invoke strlen when not needed.
8950 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
8951 (XD_DEBUG_MESSAGE): Don't waste a byte.
8953 * callproc.c (getenv_internal_1, getenv_internal)
8954 (Fgetenv_internal):
8955 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
8957 * lread.c (invalid_syntax): Omit length argument.
8958 All uses changed. This doesn't fix a bug, but it simplifies the
8959 code away from its former Hollerith-constant appearance, and it's
8960 one less 'int' to worry about when looking at integer-overflow issues.
8961 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
8963 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
8964 This didn't break anything, but it didn't help either.
8965 It's confusing to put a bogus integer in a place where the actual
8966 value does not matter.
8967 (LIST_END_P): Remove unused macro and its bogus comment.
8968 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
8970 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
8971 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
8972 implementation.
8973 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
8974 We prefer signed types, and the value cannot exceed the EMACS_INT
8975 range anyway (because otherwise the length would not be representable).
8976 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
8977 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
8978 This avoids a GCC warning when WIDE_EMACS_INT.
8980 * indent.c (sane_tab_width): New function.
8981 (current_column, scan_for_column, Findent_to, position_indentation)
8982 (compute_motion): Use it. This is just for clarity.
8983 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
8985 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
8987 * lisp.h (lint_assume): New macro.
8988 * composite.c (composition_gstring_put_cache):
8989 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
8991 * editfns.c, insdel.c:
8992 Omit unnecessary forward decls, to simplify future changes.
8994 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
8996 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
8998 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
8999 Use much-faster test for byte-length change.
9000 Don't assume string byte-length fits in 'int'.
9001 Check that character arg fits in 'int'.
9002 (mapcar1): Declare byte as byte, for clarity.
9004 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
9006 * fns.c (concat): Catch string overflow earlier.
9007 Do not rely on integer wraparound.
9009 * dispextern.h (struct it.overlay_strings_charpos)
9010 (struct it.selective): Now EMACS_INT, not int.
9011 * xdisp.c (forward_to_next_line_start)
9012 (back_to_previous_visible_line_start)
9013 (reseat_at_next_visible_line_start, next_element_from_buffer):
9014 Don't arbitrarily truncate the value of 'selective' to int.
9016 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
9018 * composite.c: Don't truncate sizes to 'int'.
9019 (composition_gstring_p, composition_reseat_it)
9020 (composition_adjust_point): Use EMACS_INT, not int.
9021 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
9022 not EMACS_UINT, for indexes.
9024 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
9026 * buffer.c: Include <verify.h>.
9027 (struct sortvec.priority, struct sortstr.priority):
9028 Now EMACS_INT, not int.
9029 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
9030 (struct sortstr.size, record_overlay_string)
9031 (struct sortstrlist.size, struct sortlist.used):
9032 Don't truncate size to int.
9033 (record_overlay_string): Check for size-calculation overflow.
9034 (init_buffer_once): Check at compile-time, not run-time.
9036 2011-06-22 Jim Meyering <meyering@redhat.com>
9038 Don't leak an XBM-image-sized buffer
9039 * image.c (xbm_load): Free the image buffer after using it.
9041 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
9043 Port to Sun C.
9044 * composite.c (find_automatic_composition): Omit needless 'return 0;'
9045 that Sun C diagnosed.
9046 * fns.c (secure_hash): Fix pointer signedness issue.
9047 * intervals.c (static_offset_intervals): New function.
9048 (offset_intervals): Use it.
9050 2011-06-21 Leo Liu <sdl.web@gmail.com>
9052 * deps.mk (fns.o):
9053 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
9054 sha512.h.
9056 * fns.c (secure_hash): Rename from crypto_hash_function and change
9057 the first arg to accept symbols.
9058 (Fsecure_hash): New primitive.
9059 (syms_of_fns): New symbols.
9061 2011-06-20 Deniz Dogan <deniz@dogan.se>
9063 * process.c (Fset_process_buffer): Clarify return value in
9064 docstring.
9066 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
9068 * dispnew.c (add_window_display_history): Use BVAR.
9070 * xdisp.c (debug_method_add): Use BVAR.
9071 (check_window_end, dump_glyph_matrix, dump_glyph)
9072 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
9074 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
9075 Likewise.
9077 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
9078 check till after the cache is created in init_frame_faces.
9080 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
9082 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
9084 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
9086 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
9087 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
9088 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
9090 Improve buffer-overflow checking (Bug#8873).
9091 * fileio.c (Finsert_file_contents):
9092 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
9093 Remove the old (too-loose) buffer overflow checks.
9094 They weren't needed, since make_gap checks for buffer overflow.
9095 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
9096 The old code merely checked for Emacs fixnum overflow, and relied
9097 on undefined (wraparound) behavior. The new code avoids undefined
9098 behavior, and also checks for ptrdiff_t and/or size_t overflow.
9100 * editfns.c (Finsert_char): Don't dump core with very negative counts.
9101 Tune. Don't use wider integers than needed. Don't use alloca.
9102 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
9104 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
9106 * insdel.c, lisp.h (buffer_overflow): New function.
9107 (insert_from_buffer_1, replace_range, replace_range_2):
9108 * insdel.c (make_gap_larger):
9109 * editfns.c (Finsert_char):
9110 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
9112 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
9114 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
9116 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
9118 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
9119 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
9121 * fileio.c: Don't assume EMACS_INT fits in off_t.
9122 (emacs_lseek): New static function.
9123 (Finsert_file_contents, Fwrite_region): Use it.
9124 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
9126 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
9128 * fns.c: Don't overflow int when computing a list length.
9129 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
9130 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
9131 truncation on 64-bit hosts. Check for QUIT every
9132 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
9133 faster and is responsive enough.
9134 (Flength): Report an error instead of overflowing an integer.
9135 (Fsafe_length): Return a float if the value is not representable
9136 as a fixnum. This shouldn't happen except in contrived situations.
9137 (Fnthcdr, Fsort): Don't assume list length fits in int.
9138 (Fcopy_sequence): Don't assume vector length fits in int.
9140 * alloc.c: Check that resized vectors' lengths fit in fixnums.
9141 (header_size, word_size): New constants.
9142 (allocate_vectorlike): Don't check size overflow here.
9143 (allocate_vector): Check it here instead, since this is the only
9144 caller of allocate_vectorlike that could cause overflow.
9145 Check that the new vector's length is representable as a fixnum.
9147 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
9148 The previous code was bogus. For example, next_almost_prime (32)
9149 returned 39, which is undesirable as it is a multiple of 3; and
9150 next_almost_prime (24) returned 25, which is a multiple of 5 so
9151 why was the code bothering to check for multiples of 7?
9153 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
9155 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
9157 Variadic C functions now count arguments with ptrdiff_t.
9158 This partly undoes my 2011-03-30 change, which replaced int with size_t.
9159 Back then I didn't know that the Emacs coding style prefers signed int.
9160 Also, in the meantime I found a few more instances where arguments
9161 were being counted with int, which may truncate counts on 64-bit
9162 machines, or EMACS_INT, which may be unnecessarily wide.
9163 * lisp.h (struct Lisp_Subr.function.aMANY)
9164 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
9165 Arg counts are now ptrdiff_t, not size_t.
9166 All variadic functions and their callers changed accordingly.
9167 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
9168 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
9169 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
9170 * callint.c (Fcall_interactively): Check arg count for overflow,
9171 to avoid potential buffer overrun. Use signed char, not 'int',
9172 for 'varies' array, so that we needn't bother to check its size
9173 calculation for overflow.
9174 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
9175 * eval.c (apply_lambda):
9176 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
9177 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
9178 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
9180 * callint.c (Fcall_interactively): Don't use index var as event count.
9182 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
9183 * mem-limits.h (SIZE): Remove; no longer used.
9185 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
9187 Remove unnecessary casts.
9188 * xterm.c (x_term_init):
9189 * xfns.c (x_set_border_pixel):
9190 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
9191 These aren't needed now that we assume ANSI C.
9193 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
9194 It's more likely to cause problems (due to unsigned overflow)
9195 than to cure them.
9197 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
9199 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
9201 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
9203 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
9205 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
9207 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
9209 GLYPH_CODE_FACE returns EMACS_INT, not int.
9210 * dispextern.h (merge_faces):
9211 * xfaces.c (merge_faces):
9212 * xdisp.c (get_next_display_element, next_element_from_display_vector):
9213 Don't assume EMACS_INT fits in int.
9215 * character.h (CHAR_VALID_P): Remove unused parameter.
9216 * fontset.c, lisp.h, xdisp.c: All uses changed.
9218 * editfns.c (Ftranslate_region_internal): Omit redundant test.
9220 * fns.c (concat): Minor tuning based on overflow analysis.
9221 This doesn't fix any bugs. Use int to hold character, instead
9222 of constantly refetching from Emacs object. Use XFASTINT, not
9223 XINT, for value known to be a character. Don't bother comparing
9224 a single byte to 0400, as it's always less.
9226 * floatfns.c (Fexpt):
9227 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
9229 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
9230 for characters.
9232 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
9234 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
9235 Without this fix, on a 64-bit host (aset S 0 4294967386) would
9236 incorrectly succeed when S was a string, because 4294967386 was
9237 truncated before it was used.
9239 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
9240 Otherwise, an out-of-range integer could cause undefined behavior
9241 on a 64-bit host.
9243 * composite.c: Use int, not EMACS_INT, for characters.
9244 (fill_gstring_body, composition_compute_stop_pos): Use int, not
9245 EMACS_INT, for values that are known to be in character range.
9246 This doesn't fix any bugs but is the usual style inside Emacs and
9247 may generate better code on 32-bit machines.
9249 Make sure a 64-bit char is never passed to ENCODE_CHAR.
9250 This is for reasons similar to the recent CHAR_STRING fix.
9251 * charset.c (Fencode_char): Check that character arg is actually
9252 a character. Pass an int to ENCODE_CHAR.
9253 * charset.h (ENCODE_CHAR): Verify that the character argument is no
9254 wider than 'int', as a compile-time check to prevent future regressions
9255 in this area.
9257 * character.c (char_string): Remove unnecessary casts.
9259 Make sure a 64-bit char is never passed to CHAR_STRING.
9260 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
9261 by silently ignoring the top 32 bits, allowing some values
9262 that were far too large to be valid characters.
9263 * character.h: Include <verify.h>.
9264 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
9265 arguments are no wider than unsigned, as a compile-time check
9266 to prevent future regressions in this area.
9267 * data.c (Faset):
9268 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
9269 (Fsubst_char_in_region):
9270 * fns.c (concat):
9271 * xdisp.c (decode_mode_spec_coding):
9272 Adjust to CHAR_STRING's new requirement.
9273 * editfns.c (Finsert_char, Fsubst_char_in_region):
9274 * fns.c (concat): Check that character args are actually
9275 characters. Without this test, these functions did the wrong
9276 thing with wildly out-of-range values on 64-bit hosts.
9278 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
9279 These casts should not be needed on 32-bit hosts, either.
9280 * keyboard.c (read_char):
9281 * lread.c (Fload): Remove casts to unsigned.
9283 * lisp.h (UNSIGNED_CMP): New macro.
9284 This fixes comparison bugs on 64-bit hosts.
9285 (ASCII_CHAR_P): Use it.
9286 * casefiddle.c (casify_object):
9287 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
9288 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
9289 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
9290 * dispextern.h (FACE_FROM_ID):
9291 * keyboard.c (read_char): Use UNSIGNED_CMP.
9293 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
9294 not to EMACS_INT, to avoid GCC warning.
9296 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
9298 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
9299 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
9300 isn't needed on 32-bit machines.
9302 * buffer.c (Fgenerate_new_buffer_name):
9303 Use EMACS_INT for count, not int.
9304 (advance_to_char_boundary): Return EMACS_INT, not int.
9306 * data.c (Qcompiled_function): Now static.
9308 * window.c (window_body_lines): Now static.
9310 * image.c (gif_load): Rename local to avoid shadowing.
9312 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
9313 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
9314 * alloc.c (make_save_value): Integer argument is now of type
9315 ptrdiff_t, not int.
9316 (mark_object): Use ptrdiff_t, not int.
9317 * lisp.h (pD): New macro.
9318 * print.c (print_object): Use it.
9320 * alloc.c: Use EMACS_INT, not int, to count objects.
9321 (total_conses, total_markers, total_symbols, total_vector_size)
9322 (total_free_conses, total_free_markers, total_free_symbols)
9323 (total_free_floats, total_floats, total_free_intervals)
9324 (total_intervals, total_strings, total_free_strings):
9325 Now EMACS_INT, not int. All uses changed.
9326 (Fgarbage_collect): Compute overall total using a double, so that
9327 integer overflow is less likely to be a problem. Check for overflow
9328 when converting back to an integer.
9329 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
9330 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
9331 These were 'int' variables that could overflow on 64-bit hosts;
9332 they were never used, so remove them instead of repairing them.
9333 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
9334 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
9335 Previously, this ceilinged at INT_MAX, but that doesn't work on
9336 64-bit machines.
9337 (allocate_pseudovector): Don't use EMACS_INT when int would do.
9339 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
9340 (allocate_vectorlike): Check for ptrdiff_t overflow.
9341 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
9342 when a (possibly-narrower) signed value would do just as well.
9343 We prefer using signed arithmetic, to avoid comparison confusion.
9345 * alloc.c: Catch some string size overflows that we were missing.
9346 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
9347 for convenience in STRING_BYTES_MAX.
9348 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
9349 The definition here is exact; the one in lisp.h was approximate.
9350 (allocate_string_data): Check for string overflow. This catches
9351 some instances we weren't catching before. Also, it catches
9352 size_t overflow on (unusual) hosts where SIZE_MAX <= min
9353 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
9354 and ptrdiff_t and EMACS_INT are both 64 bits.
9356 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
9357 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
9358 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
9360 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
9362 * alloc.c (Fmake_string): Check for out-of-range init.
9364 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
9366 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
9368 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>

9860 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
9862 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
9863 Do not assume that spare memory exists; that assumption is valid
9864 only if SYSTEM_MALLOC.
9865 (LARGE_REQUEST): New macro, so that the issue of large requests
9866 is separated from the issue of spare memory.
9868 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
9870 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal
9871 format. (Bug#8806)

9921 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
9922 (bidi_cache_search, bidi_cache_iterator_state)
9923 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)

9927 (bidi_paragraph_init, bidi_resolve_explicit_1)
9928 (bidi_level_of_next_char): Call bidi_fetch_char and

9932 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
9933 definitions.
9934 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
9935 instead of using explicit *_CHAR codes.
9936 (bidi_resolve_explicit, bidi_resolve_weak):

9938 bidirectional text is supported only in multibyte buffers.
9939 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
9940 it to initialize the frame_window_p member of struct bidi_it.

9944 bidi_it->nchars is non-positive.
9945 (bidi_level_of_next_char): Don't try to lookup the cache for the
9946 next/previous character if nothing is cached there yet, or if we
9947 were just reseat()'ed to a new position.
9949 * xdisp.c (set_cursor_from_row): Set start and stop points
9950 according to the row's direction when priming the loop that looks
9951 for the glyph on which to display cursor.

9953 (display_prop_intangible_p): Reimplement to call
9954 handle_display_spec instead of single_display_spec_intangible_p.
9955 Accept 3 additional arguments needed by handle_display_spec.
9956 This fixes incorrect cursor motion across display property with complex
9957 values: lists, `(when COND...)' forms, etc.

9963 last portion of handle_display_prop.
9964 (compute_display_string_pos): Accept additional argument
9965 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
9966 value of a `display' property is a "replacing spec".
9967 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
9968 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
9969 the display property, but just return a value indicating whether
9970 the display property will replace the characters it covers.
9971 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
9972 frame_window_p members of struct bidi_it.
9973 (compute_display_string_pos, compute_display_string_end):
9974 New functions.

9996 All callers changed. (Bug#8762)
9998 * gnutls.c: Use Emacs's memory allocators.
9999 Without this change, the gnutls library would invoke malloc etc.
10000 directly, which causes problems on non-SYNC_INPUT hosts, and which
10001 runs afoul of improving memory_full behavior. (Bug#8761)
10002 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
10003 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
10004 xfree instead of the default malloc, realloc, free.
10005 (Fgnutls_boot): No need to check for memory allocation failure,
10006 since xmalloc does that for us.
10008 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
10009 * category.c (hash_get_category_set):
10010 * ccl.c (ccl_driver):
10011 * charset.c (Fdefine_charset_internal):

10024 * image.c (make_image, search_image_cache, lookup_image)
10025 (xpm_put_color_table_h):
10026 * lisp.h (struct Lisp_Hash_Table):
10027 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
10028 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
10029 for hashes and hash indexes, instead of 'unsigned' and 'int'.
10030 * alloc.c (allocate_vectorlike):
10031 Check for overflow in vector size calculations.
10032 * ccl.c (ccl_driver):
10033 Check for overflow when converting EMACS_INT to int.
10034 * fns.c, image.c: Remove unnecessary static decls that would otherwise
10035 need to be updated by these changes.
10036 * fns.c (make_hash_table, maybe_resize_hash_table):
10037 Check for integer overflow with large hash tables.
10038 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
10039 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
10040 (SXHASH_REDUCE): New macro.
10041 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
10042 Use it instead of discarding useful hash info with large hash values.
10043 (sxhash_float): New function.
10044 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
10045 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
10046 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
10047 Rewrite to use FIXNUM_BITS, as this simplifies things.
10048 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
10049 Adjust signatures to match updated version of code.
10050 (consing_since_gc): Now EMACS_INT, since a single hash table can
10051 use more than INT_MAX bytes.
10053 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
10055 Make it possible to build with GCC-4.6+ -O2 -flto.
10057 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
10059 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
10061 * minibuf.c (get_minibuffer, read_minibuf_unwind):
10062 Call minibuffer-inactive-mode.
10064 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
10066 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
10067 Update dependencies.
10069 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10071 * data.c (init_data): Remove code for UTS, this system is not
10072 supported anymore.
10074 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10076 Don't force ./temacs to start in terminal mode.
10078 * frame.c (make_initial_frame): Initialize faces in all cases, not
10079 only when CANNOT_DUMP is defined.
10080 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
10082 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10084 * dispnew.c (add_window_display_history): Use const for the string
10085 pointer. Remove declaration, not needed.
10087 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
10089 Use 'inline', not 'INLINE'.
10090 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
10091 * alloc.c, fontset.c (INLINE): Remove.
10092 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
10093 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
10094 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
10095 * gmalloc.c (register_heapinfo): Use inline unconditionally.
10096 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
10098 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10100 Make it possible to run ./temacs.
10102 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
10103 syms_of_callproc does the same thing. Remove test for
10104 "initialized", do it in the caller.
10105 * emacs.c (main): Avoid calling set_initial_environment when dumping.
10107 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
10109 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
10110 (read_minibuf): Use get_minibuffer.
10111 (syms_of_minibuf): Use DEFSYM.
10112 (Qmetadata): New var.

10114 (syms_of_data): Use DEFSYM.
10116 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
10118 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
10119 (CCL_CODE_MIN): New macro.
10121 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
10123 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
10125 * eval.c (Qdebug): Now static.
10126 * lisp.h (Qdebug): Remove decl. This reverts a part of the
10127 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
10128 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
10130 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
10132 * image.c: Various fixes to ImageMagick code comments.
10133 (Fimagemagick_types): Doc fix.
10135 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
10137 Minor fixes prompted by GCC 4.6.0 warnings.
10139 * xselect.c (converted_selections, conversion_fail_tag): Now static.
10141 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
10142 (x_clipboard_manager_save_all): Move extern decl to ...
10143 * xterm.h: ... here, so that it can be checked for consistency.
10145 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
10147 * xselect.c (x_clipboard_manager_save_frame)
10148 (x_clipboard_manager_save_all): New functions.
10149 (Fx_clipboard_manager_save): Lisp function deleted.
10151 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
10152 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
10154 * xterm.h: Update prototype.
10156 2011-05-28 William Xu <william.xwl@gmail.com>
10158 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
10159 exiting (Bug#8239).
10161 2011-05-28 Jim Meyering <meyering@redhat.com>
10163 Avoid a sign-extension bug in crypto_hash_function.
10164 * fns.c (to_uchar): Define.
10165 (crypto_hash_function): Use it to convert some newly-signed
10166 variables to unsigned, to avoid sign-extension bugs. For example,
10167 without this change, (md5 "truc") would evaluate to
10168 45723a2aff78ff4fff7fff1114760e62 rather than the expected
10169 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
10170 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
10172 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10174 Integer overflow fixes.
10176 * dbusbind.c: Serial number integer overflow fixes.
10177 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
10178 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
10179 to hold a serial number that is too large for a fixnum.
10180 (Fdbus_method_return_internal, Fdbus_method_error_internal):
10181 Check for serial numbers out of range. Decode any serial number
10182 that was so large that it became a float. (Bug#8722)
10184 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
10185 (Fdbus_call_method, Fdbus_call_method_asynchronously):
10186 Use XFASTINT rather than XUINT when numbers are nonnegative.
10187 (xd_append_arg, Fdbus_method_return_internal):
10188 (Fdbus_method_error_internal): Likewise. Also, for unsigned
10189 arguments, check that Lisp number is nonnegative, rather than
10190 silently wrapping negative numbers around. (Bug#8722)
10191 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
10192 (Bug#8722)
10194 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
10196 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
10198 ccl: Add integer overflow checks.
10199 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
10200 (IN_INT_RANGE): New macros.
10201 (ccl_driver): Use them to check for integer overflow when
10202 decoding a CCL program. Many of the new checks are whether XINT (x)
10203 fits in int; it doesn't always, on 64-bit hosts. The new version
10204 doesn't catch all possible integer overflows, but it's an
10205 improvement. (Bug#8719)
10207 * alloc.c (make_event_array): Use XINT, not XUINT.
10208 There's no need for unsigned here.
10210 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
10211 This follows up to the 2011-05-06 change that substituted uintptr_t
10212 for EMACS_INT. This case wasn't caught back then.
10214 Rework Fformat to avoid integer overflow issues.
10215 * editfns.c: Include <float.h> unconditionally, as it's everywhere
10216 now (part of C89). Include <verify.h>.
10217 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
10218 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
10219 (Fformat): Avoid the prepass trying to compute sizes; it was only
10220 approximate and thus did not catch overflow reliably. Instead, walk
10221 through the format just once, formatting and computing sizes as we go,
10222 checking for integer overflow at every step, and allocating a larger
10223 buffer as needed. Keep track separately whether the format is
10224 multibyte. Keep only the most-recently calculated precision, rather
10225 than them all. Record whether each argument has been converted to
10226 string. Use EMACS_INT, not int, for byte and char and arg counts.
10227 Support field widths and precisions larger than INT_MAX. Avoid
10228 sprintf's undefined behavior with conversion specifications such as %#d
10229 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
10230 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
10231 formatting out-of-range floating point numbers with int
10232 formats. (Bug#8668)
10234 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
10236 * data.c: Avoid integer truncation in expressions involving floats.
10237 * data.c: Include <intprops.h>.
10238 (arith_driver): When there's an integer overflow in an expression
10239 involving floating point, convert the integers to floating point
10240 so that the resulting value does not suffer from catastrophic
10241 integer truncation. For example, on a 64-bit host (* 4
10242 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
10243 Do not rely on undefined behavior after integer overflow.
10245 merge count_size_as_multibyte, parse_str_to_multibyte
10246 * character.c, character.h (count_size_as_multibyte):
10247 Rename from parse_str_to_multibyte; all uses changed.
10248 Check for integer overflow.
10249 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
10250 since it's now a duplicate of the other. This is more of
10251 a character than a buffer op, so better that it's in character.c.
10252 * fns.c, print.c: Adjust to above changes.
10254 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
10256 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
10258 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10260 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10261 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
10262 (x_clipboard_manager_save): Now static.
10263 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
10265 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10266 (crypto_hash_function): Now static.
10267 Fix pointer signedness problems. Avoid unnecessary initializations.
10269 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
10271 * termhooks.h (Vselection_alist): Make it terminal-local.
10273 * terminal.c (create_terminal): Initialize it.
10275 * xselect.c: Support for clipboard managers.
10276 (Vselection_alist): Move to termhooks.h as terminal-local var.
10277 (LOCAL_SELECTION): New macro.
10278 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
10279 (symbol_to_x_atom): Remove gratuitous arg.
10280 (x_handle_selection_request, lisp_data_to_selection_data)
10281 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
10282 (x_own_selection, x_get_local_selection, x_convert_selection):
10283 New arg, specifying work frame. Use terminal-local Vselection_alist.
10284 (some_frame_on_display): Delete unused function.
10285 (Fx_own_selection_internal, Fx_get_selection_internal)
10286 (Fx_disown_selection_internal, Fx_selection_owner_p)
10287 (Fx_selection_exists_p): New optional frame arg.
10288 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
10289 (x_handle_selection_clear): Don't treat other terminals with the
10290 same keyboard specially. Use the terminal-local Vselection_alist.
10291 (x_clear_frame_selections): Use Frun_hook_with_args.
10293 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
10295 * xterm.h: Add support for those atoms.
10297 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
10299 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
10300 (converted_selections, conversion_fail_tag): New global variables.
10301 (x_selection_request_lisp_error): Free the above.
10302 (x_get_local_selection): Remove unnecessary code.
10303 (x_reply_selection_request): Args changed; handle arbitrary array
10304 of converted selections stored in converted_selections.
10305 Separate the XChangeProperty and SelectionNotify steps.
10306 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
10307 (x_convert_selection): New function.
10308 (x_handle_selection_event): Simplify.
10309 (x_get_foreign_selection): Don't ignore incoming requests while
10310 waiting for an answer; this will fail when we implement
10311 SAVE_TARGETS, and seems unnecessary anyway.
10312 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
10313 (Vx_sent_selection_functions): Doc fix.
10315 2011-05-26 Leo Liu <sdl.web@gmail.com>
10317 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
10319 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10321 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
10323 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
10324 for fringe update if it has periodic bitmap.
10325 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
10326 and fringe_bitmap_periodic_p.
10328 * fringe.c (get_fringe_bitmap_data): New function.
10329 (draw_fringe_bitmap_1, update_window_fringes): Use it.
10330 (update_window_fringes): Record periodicity of fringe bitmap in glyph
10331 row. Mark glyph row for fringe update if periodicity changed.
10333 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
10334 for fringe update unless it has periodic bitmap.
10336 2011-05-25 Kenichi Handa <handa@m17n.org>
10338 * xdisp.c (get_next_display_element): Set correct it->face_id for
10339 a static composition.
10341 2011-05-24 Leo Liu <sdl.web@gmail.com>
10343 * deps.mk (fns.o):
10344 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
10346 * fns.c (crypto_hash_function, Fsha1): New function.
10347 (Fmd5): Use crypto_hash_function.
10348 (syms_of_fns): Add Ssha1.
10350 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
10352 * gnutls.c: Remove unused macros.
10353 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
10354 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
10355 Remove macros that are defined and never used.
10356 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
10358 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10360 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
10361 (Fx_get_selection_internal): Minor cleanup.
10362 (Fx_own_selection_internal): Rename arguments for consistency with
10363 select.el.
10365 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
10367 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
10369 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10371 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
10373 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10375 * dispnew.c (scrolling_window): Don't exclude the case that the
10376 last enabled row in the desired matrix touches the bottom boundary.
10378 2011-05-21 Glenn Morris <rgm@gnu.org>
10380 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
10381 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
10382 and add some more files.
10384 2011-05-20 Eli Zaretskii <eliz@gnu.org>
10386 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
10387 report_file_error introduced by the change from 2011-05-07.
10389 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
10391 * systime.h (Time): Define only if emacs is defined.
10392 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
10393 where the include path doesn't have X11/X.h by default. See
10394 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
10396 2011-05-20 Kenichi Handa <handa@m17n.org>
10398 * composite.c (find_automatic_composition): Fix previous change.
10400 2011-05-20 Glenn Morris <rgm@gnu.org>
10402 * lisp.mk: New file, split from Makefile.in.
10403 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
10404 (shortlisp): Remove.
10405 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
10407 2011-05-19 Glenn Morris <rgm@gnu.org>
10409 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
10410 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
10411 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
10412 (lisp): Set the order to that of loadup.el.
10413 (shortlisp): Make it a copy of $lisp.
10414 (SOME_MACHINE_LISP): Remove.
10415 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
10416 Use just $shortlisp, not $SOME_MACHINE_LISP too.
10418 2011-05-18 Kenichi Handa <handa@m17n.org>
10420 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
10421 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
10422 (find_automatic_composition): Mostly rewrite for efficiency.
10424 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
10426 * makefile.w32-in: Update dependencies.
10428 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
10430 * menu.c: Include limits.h (fixes the MS-Windows build broken by
10431 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
10433 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
10435 Fix some integer overflow issues, such as string length overflow.
10437 * insdel.c (count_size_as_multibyte): Check for string overflow.
10439 * character.c (lisp_string_width): Check for string overflow.
10440 Use EMACS_INT, not int, for string indexes and lengths; in
10441 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
10442 the resulting string length overflows an EMACS_INT; instead,
10443 report a string overflow if no precision given. When checking for
10444 precision exhaustion, use a check that cannot possibly have
10445 integer overflow. (Bug#8675)
10446 * character.h (lisp_string_width): Adjust to new signature.
10448 * alloc.c (string_overflow): New function.
10449 (Fmake_string): Use it. This doesn't change behavior, but saves
10450 a few bytes and will simplify future changes.
10451 * character.c (string_escape_byte8): Likewise.
10452 * lisp.h (string_overflow): New decl.
10454 Fixups, following up to the user-interface timestamp change.
10455 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
10456 for UI timestamps, instead of unsigned long.
10457 * msdos.c (mouse_get_pos): Likewise.
10458 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
10459 * w32gui.h (Time): Define by including "systime.h" rather than by
10460 declaring it ourselves. (Bug#8664)
10462 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
10463 * image.c (clear_image_cache): Likewise.
10465 * term.c (term_mouse_position): Don't assume time_t wraparound.
10467 Be more systematic about user-interface timestamps.
10468 Before, the code sometimes used 'Time', sometimes 'unsigned long',
10469 and sometimes 'EMACS_UINT', to represent these timestamps.
10470 This change causes it to use 'Time' uniformly, as that's what X uses.
10471 This makes the code easier to follow, and makes it easier to catch
10472 integer overflow bugs such as Bug#8664.
10473 * frame.c (Fmouse_position, Fmouse_pixel_position):
10474 Use Time, not unsigned long, for user-interface timestamps.
10475 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
10476 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
10477 * keyboard.h (last_event_timestamp): Likewise.
10478 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
10479 * menu.h (xmenu_show): Likewise.
10480 * term.c (term_mouse_position): Likewise.
10481 * termhooks.h (struct input_event.timestamp): Likewise.
10482 (struct terminal.mouse_position_hook): Likewise.
10483 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
10484 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
10485 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
10486 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
10487 what it was before.
10488 * menu.h, termhooks.h: Include "systime.h", for Time.
10490 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
10491 Don't assume that the difference between two unsigned long values
10492 can fit into an integer. At this point, we know button_down_time
10493 <= event->timestamp, so the difference must be nonnegative, so
10494 there's no need to cast the result if double-click-time is
10495 nonnegative, as it should be; check that it's nonnegative, just in
10496 case. This bug is triggered when events are more than 2**31 ms
10497 apart (about 25 days). (Bug#8664)
10499 * xselect.c (last_event_timestamp): Remove duplicate decl.
10500 (x_own_selection): Remove needless cast to unsigned long.
10502 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
10503 that always fit in int. Use a sentinel instead of a counter, to
10504 avoid a temp and to allay GCC's concerns about possible int overflow.
10505 * frame.h (struct frame): Use int for menu_bar_items_used
10506 instead of EMACS_INT, since it always fits in int.
10508 * menu.c (grow_menu_items): Check for int overflow.
10510 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
10512 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
10513 Before, the code was not consistent. These values cannot exceed
10514 2**31 - 1 so there's no need to make them unsigned.
10515 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
10516 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
10517 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
10518 as modifiers.
10519 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
10521 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
10522 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
10523 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
10524 presumably because the widths might not match.
10526 * window.c (size_window): Avoid needless test at loop start.
10528 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
10530 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
10532 2011-05-12 Drew Adams <drew.adams@oracle.com>
10534 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
10536 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10538 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
10539 `width' to `bar_area_x' and `bar_area_width', respectively.
10540 (x_scroll_run): Take account of fringe background extension.
10542 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
10543 Rename local vars `left' and `width' to `bar_area_x' and
10544 `bar_area_width', respectively.
10545 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
10546 background extension.
10548 2011-05-10 Jim Meyering <meyering@redhat.com>
10550 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
10552 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
10554 * image.c (Finit_image_library): Return t for built-in image types,
10555 like pbm and xbm. (Bug#8640)
10557 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
10559 * w32menu.c (set_frame_menubar): Fix submenu allocation.
10561 2011-05-07 Eli Zaretskii <eliz@gnu.org>
10563 * w32console.c (Fset_screen_color): Doc fix.
10564 (Fget_screen_color): New function.
10565 (syms_of_ntterm): Defsubr it.
10567 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
10568 unlink the temporary file if Fcall_process didn't create it in the
10569 first place.
10570 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
10571 child process will be redirected to a file specified with `:file'.
10572 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
10573 cue to call_process_cleanup not to close that handle.
10575 2011-05-07 Ben Key <bkey76@gmail.com>
10577 * makefile.w32-in: The bootstrap-temacs rule now makes use of
10578 one of two shell specific rules, either bootstrap-temacs-CMD or
10579 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
10580 to the previous implementation of the bootstrap-temacs rule.
10581 The bootstrap-temacs-CMD rule is similar to the previous
10582 implementation of the bootstrap-temacs rule except that it
10583 makes use of the ESC_CFLAGS variable instead of the CFLAGS
10584 variable.
10586 These changes, along with some changes to nt/configure.bat,
10587 nt/gmake.defs, and nt/nmake.defs, are required to extend my
10588 earlier fix to add support for --cflags and --ldflags options
10589 that include quotes so that it works whether make uses cmd or
10590 sh as the shell.
10592 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
10594 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
10595 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
10596 is a constant.
10597 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
10598 a string. Handle both cases.
10599 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
10600 (Fdbus_register_method): Use Qinvalid_function.
10602 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
10604 * makefile.w32-in: Update dependencies.
10605 (LISP_H): Add inttypes.h and stdin.h.
10606 (PROCESS_H): Add unistd.h.
10608 2011-05-06 Eli Zaretskii <eliz@gnu.org>
10610 * lread.c: Include limits.h (fixes the MS-Windows build broken by
10611 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
10613 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
10615 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
10617 * term.c (vfatal): Remove stray call to va_end.
10618 It's not needed and the C Standard doesn't allow it here anyway.
10620 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
10621 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
10623 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
10624 bytes.
10626 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
10628 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
10630 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
10632 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
10634 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
10636 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
10637 * charset.c (Fdefine_charset_internal): Don't initialize
10638 charset.code_space[15]. The value was garbage, on hosts with
10639 32-bit int (Bug#8600).
10641 * lread.c (read_integer): Be more consistent with string-to-number.
10642 Use string_to_number to do the actual conversion; this avoids
10643 rounding errors and fixes some other screwups. Without this fix,
10644 for example, #x1fffffffffffffff was misread as -2305843009213693952.
10645 (digit_to_number): Move earlier, for benefit of read_integer.
10646 Return -1 if the digit is out of range for the base, -2 if it is
10647 not a digit in any supported base. (Bug#8602)
10649 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
10651 * dispnew.c (scrolling_window): Return 1 if we scrolled,
10652 to match comment at start of function. This also removes a
10653 GCC warning about overflow in a 32+64-bit port.
10655 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
10657 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
10658 Reported by Stefan Monnier in
10659 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
10660 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
10661 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
10663 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
10664 (EMACS_UINTPTR): Likewise, with uintptr_t.
10666 * lisp.h: Prefer 64-bit EMACS_INT if available.
10667 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
10668 on 32-bit hosts that have 64-bit int, so that they can access
10669 large files.
10670 However, temporarily disable this change unless the temporary
10671 symbol WIDE_EMACS_INT is defined.
10673 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
10675 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
10676 This removes an assumption that EMACS_INT and long are the same
10677 width as pointers. The assumption is true for Emacs porting targets
10678 now, but we want to make other targets possible.
10679 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
10680 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
10681 In the rest of the code, change types of integers that hold casted
10682 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
10683 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
10684 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
10685 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
10686 No need to cast type when ORing.
10687 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
10688 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
10689 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
10690 assume EMACS_INT is the same width as char *.
10691 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
10692 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
10693 Remove no-longer-needed casts.
10694 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
10695 (xg_tool_bar_help_callback, xg_make_tool_item):
10696 Use EMACS_INTPTR to hold an integer
10697 that will be cast to void *; this can avoid a GCC warning
10698 if EMACS_INT is not the same width as void *.
10699 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
10700 * xdisp.c (display_echo_area_1, resize_mini_window_1):
10701 (current_message_1, set_message_1):
10702 Use a local to convert to proper width without a cast.
10703 * xmenu.c (dialog_selection_callback): Likewise.
10705 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
10706 Also, don't assume VALBITS / RAND_BITS is less than 5,
10707 and don't rely on undefined behavior when shifting a 1 left into
10708 the sign bit.
10709 * lisp.h (get_random): Change signature to match.
10711 * lread.c (hash_string): Use size_t, not int, for hash computation.
10712 Normally we prefer signed values; but hashing is special, because
10713 it's better to use unsigned division on hash table sizes so that
10714 the remainder is nonnegative. Also, size_t is the natural width
10715 for hashing into memory. The previous code used 'int', which doesn't
10716 retain enough info to hash well into very large tables.
10717 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
10719 * dbusbind.c: Don't possibly lose pointer info when converting.
10720 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
10721 Use XPNTR rather than XHASH, so that the high-order bits of
10722 the pointer aren't lost when converting through void *.
10724 * eval.c (Fautoload): Don't double-shift a pointer.
10726 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
10728 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
10730 * gnutls.c (DEF_GNUTLS_FN):
10731 * image.c (DEF_IMGLIB_FN): Make function pointers static.
10733 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
10735 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
10736 marker. (Bug#8610)
10738 2011-05-05 Eli Zaretskii <eliz@gnu.org>
10740 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
10741 New version that can reserve upto 2GB of heap space.
10743 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
10745 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
10747 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
10749 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to

10752 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
10754 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
10755 Update dependencies.
10757 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
10759 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
10760 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
10761 Remove unused parameter `fildes'.
10762 * process.c (read_process_output, send_process): Don't pass it.
10764 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
10766 Fix previous change: the library cache is defined in w32.c.
10767 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
10768 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
10770 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
10772 Implement dynamic loading of GnuTLS on Windows.
10774 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.

10802 * w32.c (QCloaded_from, Vlibrary_cache): Define.
10803 (w32_delayed_load): Move from image.c. When loading a library, record
10804 its filename in the :loaded-from property of the library id.
10805 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
10806 Initialize and staticpro them.
10807 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
10809 * process.c: Include lisp.h before w32.h, not after.
10810 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
10811 instead of gnutls_record_check_pending.
10813 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
10815 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
10817 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
10818 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
10819 as passed in.
10821 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
10823 * xterm.c (x_set_frame_alpha): Do not set property on anything
10824 else than FRAME_X_OUTER_WINDOW (Bug#8608).
10826 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
10828 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
10830 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
10832 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
10833 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

10837 (Qgnutls_bootprop_callbacks, Qgnutls_bootprop_loglevel)
10838 (Qgnutls_bootprop_hostname, Qgnutls_bootprop_verify_flags)
10839 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
10840 (Qgnutls_bootprop_callbacks_verify): Make static.
10842 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
10844 * callproc.c: Indentation fixup.
10846 * sysdep.c (wait_for_termination_1): Make static.
10847 (wait_for_termination, interruptible_wait_for_termination):
10848 Move after wait_for_termination_1.
10850 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
10852 * sysdep.c (interruptible_wait_for_termination): New function
10853 which is like wait_for_termination, but allows keyboard
10854 interruptions.
10856 * callproc.c (Fcall_process): Add (:file "file") as an option for
10857 the STDOUT buffer.
10858 (Fcall_process_region): Ditto.
10860 2011-04-30 Eli Zaretskii <eliz@gnu.org>
10862 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
10863 rather than `XVECTOR (FOO)->size'.
10865 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
10866 inttypes.h, as a gnulib replacement is used if it not available in
10867 system headers.
10869 2011-04-21 Eli Zaretskii <eliz@gnu.org>
10871 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
10872 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
10873 of MOST_POSITIVE_FIXNUM. (Bug#8528)
10875 * coding.c (coding_alloc_by_realloc): Error out if destination
10876 will grow beyond MOST_POSITIVE_FIXNUM.
10877 (decode_coding_emacs_mule): Abort if there isn't enough place in
10878 charbuf for the composition carryover bytes. Reserve an extra
10879 space for up to 2 characters produced in a loop.
10880 (decode_coding_iso_2022): Abort if there isn't enough place in
10881 charbuf for the composition carryover bytes.
10883 2011-04-21 Eli Zaretskii <eliz@gnu.org>
10885 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
10886 aborting when %lld or %lll format is passed.
10887 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
10888 %llo or %llx format is passed. (Bug#8545)
10890 * window.c (window_scroll_line_based): Use a marker instead of
10891 simple variables to record original value of point. (Bug#7952)
10893 * doprnt.c (doprnt): Fix the case where a multibyte sequence
10894 produced by %s or %c overflows available buffer space. (Bug#8545)
10896 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
10898 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
10899 (SIZE_MAX): Move defn after all includes, as they might #define it.
10901 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
10903 * w32.c (init_environment): Warn about defaulting HOME to C:\.

10907 * keyboard.c (Qdelayed_warnings_hook): Define.
10908 (command_loop_1): Run `delayed-warnings-hook'
10909 if Vdelayed_warnings_list is non-nil.
10910 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
10911 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
10913 2011-04-28 Eli Zaretskii <eliz@gnu.org>
10915 * doprnt.c (doprnt): Don't return value smaller than the buffer
10916 size if the message was truncated. (Bug#8545).
10918 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
10920 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
10921 (Fx_window_property): #if-0 the whole functions, not just the bodies.
10923 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
10925 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
10927 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
10929 * makefile.w32-in: Update dependencies.
10931 2011-04-27 Eli Zaretskii <eliz@gnu.org>
10933 Improve `doprnt' and its usage. (Bug#8545)
10934 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
10935 `format_end'. Remove support for %l as a conversion specifier.
10936 Don't use xrealloc. Improve diagnostics when the %l size modifier
10937 is used. Update the commentary.
10939 * eval.c (verror): Simplify calculation of size_t.
10941 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
10942 messages.
10944 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
10946 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
10947 change.
10949 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
10951 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
10952 This makes this file independent of the recent pseudovector change.
10954 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
10956 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
10958 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
10959 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
10960 Remove unused local.
10961 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
10963 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
10964 GCC 4.6.0 optimizes based on type-based alias analysis.
10965 For example, if b is of type struct buffer * and v of type struct
10966 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
10967 != &v->size, and therefore "v->size = 1; b->size = 2; return
10968 v->size;" must therefore return 1. This assumption is incorrect
10969 for Emacs, since it type-puns struct Lisp_Vector * with many other
10970 types. To fix this problem, this patch adds a new type struct
10971 vectorlike_header that documents the constraints on layout of vectors
10972 and pseudovectors, and helps optimizing compilers not get fooled
10973 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
10974 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
10975 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
10976 the size member.
10977 (XSETPVECTYPE): Rewrite in terms of new macro.
10978 (XSETPVECTYPESIZE): New macro, specifying both type and size.
10979 This is a bit clearer, and further avoids the possibility of
10980 undesirable aliasing.
10981 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
10982 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
10983 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
10984 since Lisp_Subr is a special case (no "next" field).
10985 (ASIZE): Now uses header.size rather than size.
10986 All previous uses of XVECTOR (foo)->size replaced to use this macro,
10987 to avoid the hassle of writing XVECTOR (foo)->header.size.
10988 (struct vectorlike_header): New type.
10989 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
10990 object, to help avoid aliasing.
10991 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
10992 (SUBRP): Likewise, since Lisp_Subr is a special case.
10993 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
10994 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
10995 (struct Lisp_Hash_Table): Combine first two members into a single
10996 struct vectorlike_header member. All uses of "size" and "next" members
10997 changed to be "header.size" and "header.next".
10998 * buffer.h (struct buffer): Likewise.
10999 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
11000 * frame.h (struct frame): Likewise.
11001 * process.h (struct Lisp_Process): Likewise.
11002 * termhooks.h (struct terminal): Likewise.
11003 * window.c (struct save_window_data, struct saved_window): Likewise.
11004 * window.h (struct window): Likewise.
11005 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
11006 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
11007 * buffer.c (init_buffer_once): Likewise.
11008 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
11009 special case.
11010 * process.c (Fformat_network_address): Use local var for size,
11011 for brevity.
11013 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
11015 Make the Lisp reader and string-to-float more consistent (Bug#8525)
11016 * data.c (atof): Remove decl; no longer used or needed.
11017 (digit_to_number): Move to lread.c.
11018 (Fstring_to_number): Use new string_to_number function, to be
11019 consistent with how the Lisp reader treats infinities and NaNs.
11020 Do not assume that floating-point numbers represent EMACS_INT
11021 without losing information; this is not true on most 64-bit hosts.
11022 Avoid double-rounding errors, by insisting on integers when
11023 parsing non-base-10 numbers, as the documentation specifies.
11024 * lisp.h (string_to_number): New decl, replacing ...
11025 (isfloat_string): Remove.
11026 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
11027 (read1): Do not accept +. and -. as integers; this
11028 appears to have been a coding error. Similarly, do not accept
11029 strings like +-1e0 as floating point numbers. Do not report
11030 overflow for integer overflows unless the base is not 10 which
11031 means we have no simple and reliable way to continue.
11032 Break out the floating-point parsing into a new
11033 function string_to_number, so that Fstring_to_number parses
11034 floating point numbers consistently with the Lisp reader.
11035 (digit_to_number): Move here from data.c. Make it static inline.
11036 (E_CHAR, EXP_INT): Remove, replacing with ...
11037 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
11038 (string_to_number): New function, replacing isfloat_string.
11039 This function checks for valid syntax and produces the resulting
11040 Lisp float number too. Rework it so that string-to-number
11041 no longer mishandles examples like "1.0e+". Use strtoumax,
11042 so that overflow for non-base-10 numbers is reported only when
11043 there's no portable and simple way to convert to floating point.
11045 * textprop.c (set_text_properties_1): Rewrite for clarity,
11046 and to avoid GCC warning about integer overflow.
11048 * intervals.h (struct interval): Use EMACS_INT for members
11049 where EMACS_UINT might cause problems. See
11050 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
11051 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
11052 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
11053 All uses changed.
11054 (offset_intervals): Tell GCC not to worry about length overflow
11055 when negating a negative length.
11057 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
11058 (overrun_check_free): Likewise.
11060 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
11061 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
11062 word size.
11064 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11065 (gnutls_make_error): Rename local to avoid shadowing.
11066 (gnutls_emacs_global_deinit): ifdef out; not used.
11067 (Fgnutls_boot): Use const for pointer to readonly storage.
11068 Comment out unused local. Fix pointer signedness problems.
11070 * lread.c (openp): Don't stuff size_t into an 'int'.
11071 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
11072 about possible signed overflow.
11074 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11075 (GDK_KEY_g): Don't define if already defined.
11076 (xg_prepare_tooltip): Avoid pointer signedness problem.
11077 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
11079 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
11080 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
11082 * xfns.c (Fx_window_property): Simplify a bit,
11083 to make a bit faster and to avoid GCC 4.6.0 warning.
11084 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
11086 * fns.c (internal_equal): Don't assume size_t fits in int.
11088 * alloc.c (compact_small_strings): Tighten assertion a little.
11090 Replace pEd with more-general pI, and fix some printf arg casts.
11091 * lisp.h (pI): New macro, generalizing old pEd macro to other
11092 conversion specifiers. For example, use "...%"pI"d..." rather
11093 than "...%"pEd"...".
11094 (pEd): Remove. All uses replaced with similar uses of pI.
11095 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
11096 * alloc.c (check_pure_size): Don't overflow by converting size to int.
11097 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
11098 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
11099 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
11100 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
11101 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
11102 64-bit hosts.
11103 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
11104 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
11105 * print.c (safe_debug_print, print_object): Likewise.
11106 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
11107 to int.
11108 Use pI instead of if-then-else-abort. Use %p to avoid casts,
11109 avoiding the 0 flag, which is not portable.
11110 * process.c (Fmake_network_process): Use pI to avoid cast.
11111 * region-cache.c (pp_cache): Likewise.
11112 * xdisp.c (decode_mode_spec): Likewise.
11113 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
11114 behavior on 64-bit hosts with printf arg.

11116 (x_stop_queuing_selection_requests): Likewise.
11117 (x_get_window_property): Don't truncate byte count to an 'int'
11118 when tracing.
11120 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
11121 here, since it parses constructs like leading '-' and spaces,
11122 which are not wanted; and it overflows with large numbers.
11123 Instead, simply match F[0-9]+, which is what is wanted anyway.
11125 * alloc.c: Remove unportable assumptions about struct layout.
11126 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
11127 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
11128 (allocate_vectorlike, make_pure_vector): Use the new macros,
11129 plus offsetof, to remove unportable assumptions about struct layout.
11130 These assumptions hold on all porting targets that I know of, but
11131 they are not guaranteed, they're easy to remove, and removing them
11132 makes further changes easier.
11134 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
11135 This doesn't fix a bug but makes the code clearer.
11136 (string_overrun_cookie): Now const. Use initializers that
11137 don't formally overflow signed char, to avoid warnings.
11138 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
11139 can cause Emacs to crash when string overrun checking is enabled.
11140 (allocate_buffer): Don't assume sizeof (struct buffer) is a
11141 multiple of sizeof (EMACS_INT); it need not be, if
11142 alignof(EMACS_INT) < sizeof (EMACS_INT).
11143 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
11145 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

11174 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
11175 "cast to pointer from integer of different size".
11177 Improve doprnt and its use in verror. (Bug#8545)
11178 * doprnt.c (doprnt): Document the set of format control sequences
11179 supported by the function. Use SAFE_ALLOCA instead of always
11180 using `alloca'.
11182 * eval.c (verror): Don't limit the buffer size at size_max-1, that
11183 is one byte too soon. Don't use xrealloc; instead xfree and
11184 xmalloc anew.
11186 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
11188 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
11189 callbacks stage.

11192 gnutls_global_initialized. Added internals for the
11193 :verify-hostname-error, :verify-error, and :verify-flags
11194 parameters of `gnutls-boot' and documented those parameters in the
11195 docstring. Start callback support.
11196 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
11197 unless a fatal error occurred. Call gnutls_alert_send_appropriate
11198 on error. Return error code.

11258 changes in globals.h immediately force recompilation.
11259 (TAGS): Depend on $(CURDIR)/m/intel386.h and
11260 $(CURDIR)/s/ms-w32.h.

11271 (SIZE_MAX): New macro.
11272 (doprnt): Return a size_t value. 2nd arg is now size_t.
11273 Many local variables are now size_t instead of int or unsigned.
11274 Improve overflow protection. Support `l' modifier for integer
11275 conversions. Support %l conversion. Don't assume an EMACS_INT
11276 argument for integer conversions and for %c.
11278 * lisp.h (doprnt): Restore prototype.
11280 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on

11288 * eval.c (internal_lisp_condition_case): Include the handler
11289 representation in the error message.

11295 * callint.c (Fcall_interactively): When displaying error message
11296 about invalid control letter, pass the character's codepoint, not
11297 a pointer to its multibyte form. Improve display of the character
11298 in octal and display also its hex code.
11300 * character.c (char_string): Use %x to display the (unsigned)
11301 codepoint of an invalid character, to avoid displaying a bogus
11302 negative value.
11304 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
11305 `error', not SYMBOL_NAME itself.
11307 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for

11377 Define only if needed.
11379 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
11380 by pacifying GCC about it. Maybe it's time to retire it?
11381 * xfaces.c (USG, __TIMEVAL__): Likewise.
11383 * dispextern.h (struct redisplay_interface): Rename param
11384 to avoid shadowing.
11385 * termhooks.h (struct terminal): Likewise.
11386 * xterm.c (xembed_send_message): Likewise.
11388 * insdel.c (make_gap_smaller): Define only if
11389 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
11391 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
11392 it.
11394 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
11395 so that we aren't warned about unused symbols.

11432 compatible char. Avoid the old compiler warnings about
11433 out-of-range initializers by using, for example, '\xab' rather
11434 than 0xab.
11436 * xgselect.c (xgselect_initialize): Check vs interface

11486 (bcmp_translate, regcomp, regexec, print_double_string)
11487 (group_in_compile_stack, re_search, re_search_2, regex_compile)
11488 (re_compile_pattern, re_exec): Declare arguments and local
11489 variables `size_t' and `ssize_t' and return values `regoff_t', as
11490 appropriate.
11491 (POP_FAILURE_REG_OR_COUNT) <pfreg>: Declare `long'.
11492 (CHECK_INFINITE_LOOP) <failure>: Declare `ssize_t'.
11493 <compile_stack_type>: `size' and `avail' are now `size_t'.
11495 * regex.h <regoff_t>: Use ssize_t, not int.
11496 (re_search, re_search_2, re_match, re_match_2): Arguments that
11497 specify buffer/string position and length are now ssize_t and
11498 size_t. Return type is regoff_t.
11500 2011-04-16 Ben Key <bkey76@gmail.com>
11502 * nsfont.m: Fixed bugs in ns_get_family and
11503 ns_descriptor_to_entity that were caused by using free to
11504 deallocate memory blocks that were allocated by xmalloc (via
11505 xstrdup). This caused Emacs to crash when compiled with
11506 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
11507 --enable-checking=xmallocoverrun). xfree is now used to
11508 deallocate these memory blocks.
11510 2011-04-15 Paul Eggert <eggert@cs.ucla.edu>
11512 * sysdep.c (emacs_read): Remove unnecessary check vs MAX_RW_COUNT.

11523 Emacs source code has been audited now.
11524 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
11525 (emacs_read, emacs_write): Use it.
11526 * process.c (send_process): Adjust to the new signatures of
11527 emacs_write and emacs_gnutls_write. Do not attempt to store
11528 a byte offset into an 'int'; it might overflow.
11529 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

11946 * doc.c (Fdocumntation_property): New forward static decl.
11947 * eval.c (Ffetch_bytecode): New forward static decl.
11948 (Funintern): Remove extern decl; now in .h file where it belongs.
11949 * fileio.c (Fmake_symbolic_link): New forward static decl.
11950 * image.c (Finit_image_library): New forward static decl.
11951 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
11952 * intervals.h (Fprevious_property_change):
11953 (Fremove_list_of_text_properties): Remove decls.
11954 * keyboard.c (Fthis_command_keys): Remove decl.
11955 (Fcommand_execute): New forward static decl.
11956 * keymap.c (Flookup_key): New forward static decl.
11957 (Fcopy_keymap): Now static.
11958 * keymap.h (Flookup_key): Remove decl.
11959 * process.c (Fget_process): New forward static decl.
11960 (Fprocess_datagram_address): Mark as internal.
11961 * syntax.c (Fsyntax_table_p): New forward static decl.
11962 (skip_chars): Remove duplicate decl.
11963 * textprop.c (Fprevious_property_change): New forward static decl.
11964 * window.c (Fset_window_fringes, Fset_window_scroll_bars):

11971 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
11973 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
11974 change. (Bug#8496)
11976 2011-04-13 Eli Zaretskii <eliz@gnu.org>
11978 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
11979 when at ZV. (Bug#8487)
11981 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
11983 * charset.c (Fclear_charset_maps): Use xfree instead of free.
11984 (Bug#8437)
11985 * keyboard.c (parse_tool_bar_item): Likewise.
11986 * sound.c (sound_cleanup, alsa_close): Likewise.
11987 * termcap.c (tgetent): Likewise.
11988 * xfns.c (x_default_font_parameter): Likewise.
11989 * xsettings.c (read_and_apply_settings): Likewise.
11991 * alloc.c (overrun_check_malloc, overrun_check_realloc)
11992 (overrun_check_free): Protoize.
11994 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
11996 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
11997 since callers should never pass a negative size.
11998 Change the signature to match that of plain 'read' and 'write'; see
11999 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
12000 * lisp.h: Update prototypes of emacs_write and emacs_read.
12002 2011-04-11 Eli Zaretskii <eliz@gnu.org>
12004 * xdisp.c (redisplay_window): Don't try to determine the character
12005 position of the scroll margin if the window start point w->startp
12006 is outside the buffer's accessible region. (Bug#8468)
12008 2011-04-10 Eli Zaretskii <eliz@gnu.org>
12010 Fix write-region and its subroutines for buffers > 2GB.
12011 * fileio.c (a_write, e_write): Modify declaration of arguments and
12012 local variables to support buffers larger than 2GB.
12013 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
12015 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
12016 argument, local variables, and return value.
12018 * lisp.h: Update prototypes of emacs_write and emacs_read.
12020 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
12022 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
12024 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
12026 Fix more problems found by GCC 4.6.0's static checks.
12028 * xdisp.c (vmessage): Use a better test for character truncation.
12030 * charset.c (load_charset_map): <, not <=, for optimization,
12031 and to avoid potential problems with integer overflow.
12032 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
12033 * casetab.c (set_identity, shuffle): Likewise.
12034 * editfns.c (Fformat): Likewise.
12035 * syntax.c (skip_chars): Likewise.
12037 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
12038 This also lets GCC 4.6.0 generate slightly better loop code.
12040 * callint.c (Fcall_interactively): <, not <=, for optimization.
12041 (Fcall_interactively): Count the number of arguments produced,
12042 not the number of arguments given. This is simpler and lets GCC
12043 4.6.0 generate slightly better code.
12045 * ftfont.c: Distingish more carefully between FcChar8 and char.
12046 The previous code passed unsigned char * to a functions like
12047 strlen and xstrcasecmp that expect char *, which does not
12048 conform to the C standard.
12049 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
12050 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
12051 char * when the C standard requires it.
12053 * keyboard.c (read_char): Remove unused var.
12055 * eval.c: Port to Windows vsnprintf (Bug#8435).
12056 Include <limits.h>.
12057 (SIZE_MAX): Define if the headers do not.
12058 (verror): Do not give up if vsnprintf returns a negative count.
12059 Instead, grow the buffer. This ports to Windows vsnprintf, which
12060 does not conform to C99. Problem reported by Eli Zaretskii.
12061 Also, simplify the allocation scheme, by avoiding the need for
12062 calling realloc, and removing the ALLOCATED variable.
12064 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
12066 Remove invocations of doprnt, as Emacs now uses vsnprintf.
12067 But keep the doprint source code for now, as we might revamp it
12068 and use it again (Bug#8435).
12069 * lisp.h (doprnt): Remove.
12070 * Makefile.in (base_obj): Remove doprnt.o.
12071 * deps.mk (doprnt.o): Remove.
12073 error: Print 32- and 64-bit integers portably (Bug#8435).
12074 Without this change, on typical 64-bit hosts error ("...%d...", N)
12075 was used to print both 32- and 64-bit integers N, which relied on
12076 undefined behavior.
12077 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
12078 * lisp.h (error, verror): Mark as printf-like functions.
12079 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
12080 Report overflow in size calculations when allocating printf buffer.
12081 Do not truncate output string at its first null byte.
12082 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
12083 Truncate the output at a character boundary, since vsnprintf does not
12084 do that.
12085 * charset.c (check_iso_charset_parameter): Convert internal
12086 character to string before calling 'error', since %c now has the
12087 printf meaning.
12088 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
12089 overflow when computing char to be passed to 'error'. Do not
12090 pass Lisp_Object to 'error'; pass the integer instead.
12091 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
12092 formatted with plain %d.
12094 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
12096 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
12098 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
12100 * xterm.c (x_catch_errors): Remove duplicate declaration.
12102 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
12104 * xdisp.c, lisp.h (message_nolog): Remove; unused.
12106 2011-04-10 Jim Meyering <meyering@redhat.com>
12108 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
12109 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
12110 return ssize_t not "int", and use size_t as the buffer length.
12111 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
12112 * gnutls.h: Update declarations.
12113 * process.c (read_process_output): Use ssize_t, to match.
12114 (send_process): Likewise.
12116 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12118 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
12120 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12122 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
12123 Use unsigned char, to match FcChar8 type definition.
12125 * xterm.c (handle_one_xevent):
12126 * xmenu.c (create_and_show_popup_menu):
12127 * xselect.c (x_decline_selection_request)
12128 (x_reply_selection_request): Avoid type-punned deref of X events.
12130 2011-04-09 Eli Zaretskii <eliz@gnu.org>
12132 Fix some uses of `int' instead of EMACS_INT.
12133 * search.c (string_match_1, fast_string_match)
12134 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
12135 (scan_buffer, find_next_newline_no_quit)
12136 (find_before_next_newline, search_command, Freplace_match)
12137 (Fmatch_data): Make some `int' variables be EMACS_INT.
12139 * xdisp.c (display_count_lines): 3rd argument and return value now
12140 EMACS_INT. All callers changed.
12141 (pint2hrstr): Last argument is now EMACS_INT.
12143 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
12144 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
12145 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
12146 (decode_coding_utf_16, decode_coding_emacs_mule)
12147 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
12148 (decode_coding_ccl, decode_coding_charset)
12149 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
12150 (decode_coding_iso_2022, decode_coding_emacs_mule)
12151 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
12152 <char_offset, last_offset>: Declare EMACS_INT.
12153 (encode_coding_utf_8, encode_coding_utf_16)
12154 (encode_coding_emacs_mule, encode_invocation_designation)
12155 (encode_designation_at_bol, encode_coding_iso_2022)
12156 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
12157 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
12158 Declare EMACS_INT.
12159 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
12160 (encode_invocation_designation): Last argument P_NCHARS is now
12161 EMACS_INT.
12162 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
12163 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
12165 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
12166 All users changed.
12168 * ccl.c (Fccl_execute_on_string): Declare some variables
12169 EMACS_INT.
12171 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
12173 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
12175 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
12177 * process.c (Fformat_network_address): Doc fix.
12179 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
12181 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
12183 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
12185 * keyboard.c (read_char): Call Lisp function help-form-show,
12186 instead of using internal_with_output_to_temp_buffer.
12187 (Qhelp_form_show): New var.
12188 (syms_of_keyboard): Use DEFSYM macro.
12190 * print.c (internal_with_output_to_temp_buffer): Function deleted.
12192 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
12194 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
12196 * process.c (Flist_processes): Remove to Lisp.
12197 (list_processes_1): Delete.
12199 2011-04-06 Eli Zaretskii <eliz@gnu.org>
12201 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
12203 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
12205 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
12207 Fix more problems found by GCC 4.6.0's static checks.
12209 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
12211 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
12213 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
12215 * xdisp.c (vmessage): Mark as a printf-like function.
12217 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

12222 printf-like functions.
12223 (tiff_load): Add casts to remove these marks before passing them
12224 to system-supplied API.
12226 * eval.c (Fsignal): Remove excess argument to 'fatal'.
12228 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
12229 This avoids several warnings with gcc -Wstrict-overflow.
12230 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
12231 directly, rather than having caller test rule sign. This avoids
12232 some unnecessary tests.
12233 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
12234 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
12235 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
12237 * xfont.c (xfont_text_extents): Remove var that was set but not used.
12238 (xfont_open): Avoid unnecessary tests.
12240 * composite.c (composition_gstring_put_cache): Use unsigned integer.
12242 * composite.h, composite.c (composition_gstring_put_cache):
12243 Use EMACS_INT, not int, for length.
12245 * composite.h (COMPOSITION_DECODE_REFS): New macro,
12246 breaking out part of COMPOSITION_DECODE_RULE.
12247 (COMPOSITION_DECODE_RULE): Use it.
12248 * composite.c (get_composition_id): Remove unused local vars,
12249 by using the new macro.
12251 * textprop.c (set_text_properties_1): Change while to do-while,
12252 since the condition is always true at first.
12254 * intervals.c (graft_intervals_into_buffer): Mark var as used.
12255 (interval_deletion_adjustment): Return unsigned value.
12256 All uses changed.

12259 (exec_sentinel): Remove vars that were set but not used.
12260 (create_pty): Remove unnecessary "volatile"s.

12267 * syntax.c (scan_words): Remove var that was set but not used.
12268 (update_syntax_table): Use unsigned instead of int.
12270 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
12271 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
12272 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
12274 * print.c (print_error_message): Avoid int overflow.
12276 * font.c (font_list_entities): Redo for clarity,
12277 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
12279 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
12280 (font_score): Avoid potential overflow in diff calculation.
12282 * fns.c (substring_both): Remove var that is set but not used.
12283 (sxhash): Redo loop for clarity and to avoid wraparound warning.
12285 * eval.c (funcall_lambda): Rename local to avoid shadowing.
12287 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
12288 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
12289 can always succeed if overflow has undefined behavior.
12291 * search.c (boyer_moore, wordify): Remove vars set but not used.
12292 (wordify): Omit three unnecessary tests.
12294 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
12295 All callers changed. This avoids the need for an unused var.
12297 * casefiddle.c (casify_region): Remove var that is set but not used.
12299 * dired.c (file_name_completion): Remove var that is set but not used.
12301 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
12303 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
12304 (Finsert_file_contents): Remove unnecessary code checking fd.
12306 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
12307 Check for integer overflow on size calculations.
12309 * buffer.c (Fprevious_overlay_change): Remove var that is set
12310 but not used.
12312 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
12313 Remove vars that are set but not used.
12314 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
12315 (timer_check_2): Mark vars as initialized.
12317 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
12319 * image.c (lookup_image): Remove var that is set but not used.
12320 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
12322 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
12323 that are set but not used.
12325 * xfns.c (make_invisible_cursor): Don't return garbage
12326 if XCreateBitmapFromData fails (Bug#8410).
12328 * xselect.c (x_get_local_selection, x_handle_property_notify):
12329 Remove vars that are set but not used.
12331 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
12332 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
12334 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
12335 Remove var that is set but not used.
12336 (scroll_bar_windows_size): Now size_t, not int.
12337 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
12338 Check for overflow.
12340 * xfaces.c (realize_named_face): Remove vars that are set but not used.
12341 (map_tty_color) [!defined MSDOS]: Likewise.
12343 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
12345 * coding.c: Remove vars that are set but not used.
12346 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
12347 All callers changed.
12348 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
12349 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
12350 (decode_coding_charset): Remove vars that are set but not used.
12352 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
12353 that is set but not used.
12355 * print.c (print_object): Remove var that is set but not used.
12357 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
12358 The gnulib version avoids calling malloc in the usual case,
12359 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
12360 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
12361 * filelock.c (current_lock_owner): Likewise.
12362 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
12363 * sysdep.c: Include allocator.h, careadlinkat.h.
12364 (emacs_no_realloc_allocator): New static constant.
12365 (emacs_readlink): New function.
12366 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
12367 ../lib/careadlinkat.h.
12369 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
12371 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
12372 first non-nil return value).
12374 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
12376 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
12377 if not defined (Bug#8403).
12379 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
12381 * xdisp.c (display_count_lines): Remove parameter `start',
12382 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
12383 (get_char_face_and_encoding): Remove parameter `multibyte_p',

12387 and thereabouts. All callers changed.
12388 (get_per_char_metric): Remove parameter `f', unused since
12389 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
12391 2011-04-02 Jim Meyering <meyering@redhat.com>
12393 do not dereference NULL upon failed strdup
12394 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
12395 (ns_get_family): Likewise.
12397 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
12399 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
12401 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
12403 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
12404 later (Bug#8403).
12406 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
12408 Add lexical binding.
12410 * window.c (Ftemp_output_buffer_show): New fun.
12411 (Fsave_window_excursion):
12412 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
12414 * lread.c (lisp_file_lexically_bound_p): New function.
12415 (Fload): Bind Qlexical_binding.
12416 (readevalloop): Remove `evalfun' arg.
12417 Bind Qinternal_interpreter_environment.
12418 (Feval_buffer): Bind Qlexical_binding.
12419 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
12420 Mark as dynamic.
12421 (syms_of_lread): Declare `lexical-binding'.
12423 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
12425 * keyboard.c (eval_dyn): New fun.
12426 (menu_item_eval_property): Use it.
12428 * image.c (parse_image_spec): Use Ffunctionp.
12430 * fns.c (concat, mapcar1): Accept byte-code-functions.
12432 * eval.c (Fsetq): Handle lexical vars.
12433 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
12434 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
12435 (FletX, Flet): Obey lexical binding.
12436 (Fcommandp): Handle closures.
12437 (Feval): New `lexical' arg.
12438 (eval_sub): New function extracted from Feval. Use it almost
12439 everywhere where Feval was used. Look up vars in lexical env.
12440 Handle closures.
12441 (Ffunctionp): Move from subr.el.
12442 (Ffuncall): Handle closures.
12443 (apply_lambda): Remove `eval_flags'.
12444 (funcall_lambda): Handle closures and new byte-code-functions.
12445 (Fspecial_variable_p): New function.
12446 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
12447 but without exporting it to Lisp.
12449 * doc.c (Fdocumentation, store_function_docstring):
12450 * data.c (Finteractive_form): Handle closures.
12452 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
12453 interactive spec.
12455 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
12456 New byte-codes.
12457 (exec_byte_code): New function extracted from Fbyte_code to handle new
12458 calling convention for byte-code-functions. Add new byte-codes.
12460 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
12462 * alloc.c (Fmake_symbol): Init new `declared_special' field.
12464 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
12466 * xdisp.c (redisplay_internal): Fix prototype.
12468 2011-03-31 Eli Zaretskii <eliz@gnu.org>
12470 * xdisp.c (SCROLL_LIMIT): New macro.
12471 (try_scrolling): Use it when setting scroll_limit.
12472 Limit scrolling to 100 screen lines.
12473 (redisplay_window): Even when falling back on "recentering",
12474 position point in the window according to scroll-conservatively,
12475 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
12477 (try_scrolling): When point is above the window, allow searching
12478 as far as scroll_max, or one screenful, to compute vertical
12479 distance from PT to the scroll margin position. This prevents
12480 try_scrolling from unnecessarily failing when
12481 scroll-conservatively is set to a value slightly larger than the
12482 window height. Clean up the case of PT below the margin at bottom
12483 of window: scroll_max can no longer be INT_MAX. When aggressive
12484 scrolling is in use, don't let point enter the opposite scroll
12485 margin as result of the scroll.
12486 (syms_of_xdisp) <scroll-conservatively>: Document the
12487 threshold of 100 lines for never-recentering scrolling.
12489 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
12491 * dispextern.h (move_it_by_lines):
12492 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
12493 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
12494 (message_log_check_duplicate): Remove parameters `prev_bol' and
12495 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
12496 (redisplay_internal): Remove parameter `preserve_echo_area',
12497 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
12499 * indent.c (Fvertical_motion):
12500 * window.c (window_scroll_pixel_based, Frecenter):
12501 Don't pass `need_y_p' to `move_it_by_lines'.
12503 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
12505 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
12506 steal a few bits to be more compact.
12507 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
12508 Remove unneeded casts.
12510 * bytecode.c (Fbyte_code): CAR and CDR can GC.
12512 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
12514 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
12515 binding" message (bug#7967).
12517 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
12519 Fix more problems found by GCC 4.6.0's static checks.
12521 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
12522 Remove unused local var.
12524 * editfns.c (Fmessage_box): Remove unused local var.
12526 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
12527 (note_mode_line_or_margin_highlight, note_mouse_highlight):
12528 Omit unused local vars.
12529 * window.c (shrink_windows): Omit unused local var.
12530 * menu.c (digest_single_submenu): Omit unused local var.
12531 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
12532 Omit unused local var.
12534 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
12535 Don't assume string length fits in int.
12536 (keyremap_step, read_key_sequence): Use size_t for sizes.
12537 (read_key_sequence): Don't check last_real_key_start redundantly.
12539 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
12540 instead of alloca (Bug#8344).
12542 * eval.c (Fbacktrace): Don't assume nargs fits in int.
12543 (Fbacktrace_frame): Don't assume nframes fits in int.
12545 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
12547 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
12548 concerns.
12550 * term.c (produce_glyphless_glyph): Remove unnecessary test.
12552 * cm.c (calccost): Turn while-do into do-while, for clarity.
12554 * keyboard.c (syms_of_keyboard): Use the same style as later
12555 in this function when indexing through an array. This also
12556 works around GCC bug 48267.
12558 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
12560 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
12562 * chartab.c (sub_char_table_ref_and_range): Redo for slight
12563 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
12565 * keyboard.c, keyboard.h (num_input_events): Now size_t.
12566 This avoids undefined behavior on integer overflow, and is a bit
12567 more convenient anyway since it is compared to a size_t variable.
12569 Variadic C functions now count arguments with size_t, not int.
12570 This avoids an unnecessary limitation on 64-bit machines, which
12571 caused (substring ...) to crash on large vectors (Bug#8344).
12572 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
12573 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

12579 (internal_condition_case_n, run_hook_with_args, apply_lambda)
12580 (funcall_lambda, mark_backtrace): Likewise.
12581 * fns.c (concat): Likewise.
12582 * frame.c (x_set_frame_parameters): Likewise.
12583 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
12584 0 if not found, not -1. All callers changed.
12586 * alloc.c (garbage_collect): Don't assume stack size fits in int.
12587 (stack_copy_size): Now size_t, not int.
12588 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
12590 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
12592 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',

12596 * lisp.h (multibyte_char_to_unibyte):
12597 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
12598 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

12606 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12608 * keyboard.c (safe_run_hook_funcall): New function.
12609 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
12610 don't set the hook to nil, but remove the offending function instead.
12611 (Qcommand_hook_internal): Remove, unused.
12612 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
12613 Vcommand_hook_internal.
12615 * eval.c (enum run_hooks_condition): Remove.
12616 (funcall_nil, funcall_not): New functions.
12617 (run_hook_with_args): Call each function through a `funcall' argument.
12618 Remove `cond' argument, now redundant.
12619 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
12620 (Frun_hook_with_args_until_failure): Adjust accordingly.
12621 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

12625 * dispextern.h (string_buffer_position): Remove declaration.
12627 * print.c (strout): Remove parameter `multibyte', unused since
12628 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
12630 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
12631 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.

12644 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
12645 All callers changed.
12647 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
12649 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

12689 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
12691 * keyboard.c (timer_check): Remove parameter `do_it_now',
12692 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
12693 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
12694 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
12696 * keyboard.c (read_char):
12697 * w32menu.c (w32_menu_display_help):
12698 * xmenu.c (show_help_event, menu_help_callback):
12699 Adjust calls to `show_help_echo'.
12701 * gtkutil.c (xg_maybe_add_timer):
12702 * keyboard.c (readable_events):
12703 * process.c (wait_reading_process_output):
12704 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
12706 * insdel.c (adjust_markers_gap_motion):
12707 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

12793 * buffer.c (Fkill_all_local_variables):
12794 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
12795 Use Frun_hooks.
12796 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
12797 unconditionally since it does the check itself.
12799 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
12801 Fix more problems found by GCC 4.5.2's static checks.
12803 * coding.c (encode_coding_raw_text): Avoid unnecessary test
12804 the first time through the loop, since we know p0 < p1 then.
12805 This also avoids a gcc -Wstrict-overflow warning.
12807 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
12808 leading to a memory leak, possible in functions like
12809 load_charset_map_from_file that can allocate an unbounded number
12810 of objects (Bug#8318).
12812 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
12813 that could (at least in theory) be that large.
12815 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
12816 This is less likely to overflow, and avoids undefined behavior if
12817 overflow does occur. All callers changed. Use strtoul to scan
12818 for the unsigned long integer.
12819 (pint2hrstr): Simplify and tune code slightly.
12820 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
12822 * scroll.c (do_scrolling): Work around GCC bug 48228.
12823 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

12833 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
12835 * process.c (Fmake_network_process): Use socklen_t, not int,
12836 where POSIX says socklen_t is required in portable programs.
12837 This fixes a porting bug on hosts like 64-bit HP-UX, where
12838 socklen_t is wider than int (Bug#8277).
12839 (Fmake_network_process, server_accept_connection):
12840 (wait_reading_process_output, read_process_output):

12850 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
12851 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
12853 Make tparam.h and terminfo.c consistent.
12854 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
12855 Include tparam.h instead, since it declares them.
12856 * cm.h (PC): Remove extern decl; tparam.h now does this.

12858 * terminfo.c: Include tparam.h, to check interfaces.
12859 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
12860 (tparam): Adjust signature to match interface in tparam.h;
12861 this removes some undefined behavior. Check that outstring and len
12862 are zero, which they always are with Emacs.
12863 * tparam.h (PC, BC, UP): New extern decls.
12865 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
12866 (xftfont_open): Rename locals to avoid shadowing.

12907 (wav_play): Initialize a variable to 0, to prevent undefined
12908 behavior (Bug#8278).
12910 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
12912 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
12914 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
12915 clobbering (Bug#8298).
12916 * sysdep.c (sys_subshell): Likewise.
12917 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
12919 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
12920 This should get cleaned up, so that child_setup has the
12921 same signature on all platforms.
12923 * callproc.c (call_process_cleanup): Now static.
12924 (relocate_fd): Rename locals to avoid shadowing.
12926 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
12928 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
12929 not to be necessary, and produces flickering.
12931 2011-03-20 Glenn Morris <rgm@gnu.org>
12933 * config.in: Remove file.
12935 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

12980 Define only if needed.
12982 * unexelf.c (unexec): Name an expression,
12983 to avoid gcc -Wbad-function-cast warning.
12984 Use a different way to cause a compilation error if anyone uses
12985 n rather than nn, a way that does not involve shadowing.
12986 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
12988 * deps.mk (unexalpha.o): Remove; unused.
12990 New file unexec.h, the (simple) interface for unexec (Bug#8267).

12997 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
12998 Change as necessary to match prototype in unexec.h.

13050 Move decls here, to check interfaces.
13051 * process.c (get_operating_system_release): Move decl to lisp.h.
13052 * xrdb.c (get_system_name): Likewise.

13079 they're used.
13080 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
13081 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
13082 needed otherwise.
13083 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
13084 (GC_STRING_CHARS): Remove; not used.
13085 (Fmemory_limit): Cast sbrk's returned value to char *.
13087 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
13088 avoids undefined behavior in theory.
13090 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
13092 Use functions, not macros, for up- and down-casing (Bug#8254).
13093 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13094 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
13095 to use the following functions instead of these macros.
13096 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
13097 EMACS_INT, since callers assume the returned value fits in int.
13098 (upcase1): Likewise, for UPCASE_TABLE.
13099 (uppercasep, lowercasep, upcase): New static inline functions.
13100 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

13106 (regex_compile, re_search_2, re_match_2_internal):
13107 Remove unused local vars.
13108 (FREE_VAR): Rewrite so as not to use empty "else",
13109 which gcc can warn about.
13110 (regex_compile, re_match_2_internal): Mark locals as initialized.
13111 (RETALLOC_IF): Define only if needed.
13112 (WORDCHAR_P): Likewise. This one is never needed, but is used
13113 only in a comment talking about a compiler bug, so put inside
13114 the #if 0 of that comment.
13115 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
13116 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

13134 Rename locals to avoid shadowing.
13135 (Fvertical_motion): Mark locals as initialized.
13137 * casefiddle.c (casify_object, casify_region): Now static.

13142 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
13143 New macros, so that the caller can use some names other than
13144 gcpro1, gcpro2, etc.
13145 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
13146 of the new macros.
13147 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
13148 argument, for consistency with GCPRO2_VAR, etc: it is now the
13149 prefix of the variable, not the variable itself. All uses
13150 changed.
13151 * dired.c (directory_files_internal, file_name_completion):
13152 Rename locals to avoid shadowing.
13154 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
13155 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
13156 dired.c's scmp function, had undefined behavior.
13157 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13158 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
13159 * buffer.h: ... to here, because these macros use current_buffer,
13160 and the new implementation with inline functions needs to have
13161 current_buffer in scope now, rather than later when the macros
13162 are used.
13163 (downcase, upcase1): New static inline functions.
13164 (DOWNCASE, UPCASE1): Reimplement using these functions.
13165 This avoids undefined behavior in expressions like
13166 DOWNCASE (x) == DOWNCASE (y), which previously suffered
13167 from race conditions in accessing the global variables
13168 case_temp1 and case_temp2.
13169 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
13170 * lisp.h (case_temp1, case_temp2): Remove their decls.
13171 * character.h (ASCII_CHAR_P): Move from here ...
13172 * lisp.h: ... to here, so that the inline functions mentioned
13173 above can use them.

13179 Now static.
13180 (file_name_as_directory): Use const pointers when appropriate.
13181 (Fexpand_file_name): Likewise. In particular, newdir might
13182 point at constant storage, so make it a const pointer.
13183 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
13184 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
13185 signedness issues.
13186 (Fset_file_times, Finsert_file_contents, auto_save_error):
13187 Rename locals to avoid shadowing.
13189 * minibuf.c (choose_minibuf_frame_1): Now static.
13190 (Ftry_completion, Fall_completions): Rename or remove locals
13191 to avoid shadowing.
13193 * marker.c (bytepos_to_charpos): Remove; unused.
13195 * lisp.h (verify_bytepos, count_markers): New decls,
13196 so that gcc does not warn that these functions aren't declared.
13198 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
13199 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
13200 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
13201 (copy_text): Remove unused local var.
13203 * filelock.c (within_one_second): Now static.
13204 (lock_file_1): Rename local to avoid shadowing.
13206 * buffer.c (fix_overlays_before): Mark locals as initialized.
13207 (fix_start_end_in_overlays): Likewise. This function should be
13208 simplified by using pointers-to-pointers, but that's a different
13209 matter.
13210 (switch_to_buffer_1): Now static.
13211 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
13212 (report_overlay_modification): Rename locals to avoid shadowing.
13214 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
13215 Fix pointer signedness issue.
13216 (sys_subshell): Mark local as volatile if checking for lint,
13217 to suppress a gcc -Wclobbered warning that does not seem to be right.
13218 (MAXPATHLEN): Define only if needed.
13220 * process.c (serial_open, serial_configure): Move decls from here ...
13221 * systty.h: ... to here, so that they can be checked.
13223 * fns.c (get_random, seed_random): Move extern decls from here ...
13224 * lisp.h: ... to here, so that they can be checked.
13226 * sysdep.c (reset_io): Now static.
13227 (wait_for_termination_signal): Remove; unused.
13229 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

13231 Now static.
13232 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
13233 (DENSE_TABLE_SIZE): Remove; unused.
13234 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):

13240 (poll_for_input, handle_async_input): Now static.
13241 (read_char, kbd_buffer_get_event, make_lispy_position):
13242 (make_lispy_event, make_lispy_movement, apply_modifiers):
13243 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
13244 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
13245 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
13246 (read_key_sequence, read_char): Mark locals as initialized.

13251 * alloc.c (mark_kboards): ... from here.
13253 * lisp.h (force_auto_save_soon): New decl.
13255 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
13256 (DEFINE_DUMMY_FUNCTION): New macro.
13257 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
13258 Use it.
13259 (main): Add casts to avoid warnings
13260 if GCC considers string literals to be constants.
