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

302 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
304 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
305 This is more efficient than Ffile_directory_p and avoids a minor race.
307 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
309 * buffer.c (Foverlay_put): Say what the return value is
312 * fileio.c (barf_or_query_if_file_exists): Check first if the file
313 is a directory before asking whether to use the file name
315 (barf_or_query_if_file_exists): Make the "File is a directory"
316 error be more correct.
318 * fns.c (Frequire): Remove the mention of the .gz files, since
319 that's installation-specific, but keep the mention of
322 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
324 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

335 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

344 * xfaces.c (Finternal_merge_in_global_face): Modify the foreground
345 and background color parameters if they have been changed.
347 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>

351 2011-07-03 Paul Eggert <eggert@cs.ucla.edu>

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

533 * process.c (wait_reading_process_output): Bypass select if
534 waiting for a cell while ignoring keyboard input, and input is

609 Integer and buffer overflow fixes (Bug#8873).
611 * print.c (printchar, strout): Check for string overflow.
612 (PRINTPREPARE, printchar, strout):
613 Don't set size unless allocation succeeds.
615 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
616 for sizes. Check for string overflow more accurately.
617 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
619 * macros.c: Integer and buffer overflow fixes.
620 * keyboard.h (struct keyboard.kbd_macro_bufsize):
621 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
622 Use ptrdiff_t, not int, for sizes.

624 Check for size-calculation overflow.
625 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
627 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
629 * lread.c: Integer overflow fixes.
630 (read_integer): Radix is now EMACS_INT, not int,
631 to improve quality of diagnostics for out-of-range radices.
632 Calculate buffer size correctly for out-of-range radices.
633 (read1): Check for integer overflow in radices, and in
635 (read_escape): Avoid int overflow.
636 (Fload, openp, read_buffer_size, read1)
637 (substitute_object_recurse, read_vector, read_list, map_obarray):

648 (read1): Don't assume doc string length fits in int. Check for
649 out-of-range doc string lengths.
650 (read_list): Don't assume file position fits in int.
651 (read_escape): Check for hex character overflow.
653 2011-06-22 Leo Liu <sdl.web@gmail.com>
655 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
656 Move to minibuffer.el.
658 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
660 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
661 The following patches are for when GLYPH_DEBUG && !XASSERT.
662 * dispextern.h (trace_redisplay_p, dump_glyph_string):
663 * dispnew.c (flush_stdout):
664 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
665 Mark as externally visible.
666 * dispnew.c (check_window_matrix_pointers): Now static.
667 * dispnew.c (window_to_frame_vpos):
668 * xfns.c (unwind_create_frame):
669 * xterm.c (x_check_font): Remove unused local.
670 * scroll.c (CHECK_BOUNDS):
671 * xfaces.c (cache_fache): Rename local to avoid shadowing.
672 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
673 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
674 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
675 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
677 (debug_method_add): Use va_list and vsprintf rather than relying
678 on undefined behavior with wrong number of arguments.
679 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
680 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
681 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
682 since we're not interested in debugging glyphs with old libraries.
683 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
684 GCC 4.6.0's static checking.
686 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
688 Integer overflow and signedness fixes (Bug#8873).
689 A few related buffer overrun fixes, too.
691 * font.c (font_score): Use EMACS_INT, not int, to store XINT value.
693 * dispextern.h (struct face.stipple):

695 (x_bitmap_mask, x_allocate_bitmap_record)
696 (x_create_bitmap_from_data, x_create_bitmap_from_file)
697 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
698 (x_create_bitmap_from_xpm_data):
699 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
700 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
702 * xfaces.c (load_pixmap):
703 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
704 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
705 (.bitmaps_last, struct x_output.icon_bitmap):
706 Use ptrdiff_t, not int, for bitmap indexes.
707 (x_allocate_bitmap_record): Check for size overflow.
708 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
710 Use ptrdiff_t, not int, for overlay counts.
711 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
712 * editfns.c (overlays_around, get_pos_property):
713 * textprop.c (get_char_property_and_overlay):
714 * xdisp.c (next_overlay_change, note_mouse_highlight):
715 * xfaces.c (face_at_buffer_position):
716 * buffer.c (OVERLAY_COUNT_MAX): New macro.
717 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
718 (Fnext_overlay_change, Fprevious_overlay_change)
719 (mouse_face_overlay_overlaps, Foverlays_in):
720 Use ptrdiff_t, not int, for sizes.

723 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
725 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
726 (x_session_initialize): Do not assume string length fits in int.
728 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
729 This is unlikely, but can occur if DPI is outlandish.
731 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
732 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
734 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
735 * xrdb.c (magic_file_p, search_magic_path):
736 Omit last arg SUFFIX; it was always 0. All callers changed.

739 * xfont.c (xfont_match): Avoid need for strlen.
741 * xfns.c: Don't assume strlen fits in int.

744 * xdisp.c (message_log_check_duplicate): Return intmax_t,
745 not unsigned long, as we prefer signed integers. All callers changed.
746 Detect integer overflow in repeat count.
747 (message_dolog): Don't assume print length fits in 39 bytes.
748 (display_mode_element): Don't assume strlen fits in int.
750 * termcap.c: Don't assume sizes fit in int and never overflow.
751 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
752 (gobble_line): Check for size-calculation overflow.
754 * minibuf.c (Fread_buffer):
755 * lread.c (intern, intern_c_string):
756 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
757 Don't assume string length fits in int.
759 * keyboard.c (parse_tool_bar_item):
760 * gtkutil.c (style_changed_cb): Avoid need for strlen.
762 * font.c: Don't assume string length fits in int.
763 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
764 Use ptrdiff_t, not int.
765 (font_intern_prop): Don't assume string length fits in int.
766 Don't assume integer property fits in fixnum.
767 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
769 * filelock.c: Fix some buffer overrun and integer overflow issues.
770 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
771 Reformulate so as not to need the command string.
772 Invoke gzip -cd rather than gunzip, as it's more portable.
773 (lock_info_type, lock_file_1, lock_file):
774 Don't assume pid_t and time_t fit in unsigned long.
775 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
776 (current_lock_owner): Prefer signed type for sizes.
777 Use memcpy, not strncpy, where memcpy is what is really wanted.
778 Don't assume (via atoi) that time_t and pid_t fit in int.
779 Check for time_t and/or pid_t out of range, e.g., via a network share.
780 Don't alloca where an auto var works fine.
782 * fileio.c: Fix some integer overflow issues.
783 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
784 Don't assume string length fits in int.
785 (directory_file_name): Don't assume string length fits in long.
786 (make_temp_name): Don't assume pid fits in int, or that its print
787 length is less than 20.
789 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
791 * coding.c (make_subsidiaries): Don't assume string length fits in int.
793 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
795 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
796 We prefer signed integers, even for size calculations.
798 * emacs.c: Don't assume string length fits in 'int'.
799 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
800 (main): Don't invoke strlen when not needed.

807 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
809 * lread.c (invalid_syntax): Omit length argument.
810 All uses changed. This doesn't fix a bug, but it simplifies the
811 code away from its former Hollerith-constant appearance, and it's
812 one less 'int' to worry about when looking at integer-overflow issues.
813 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
815 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
816 This didn't break anything, but it didn't help either.
817 It's confusing to put a bogus integer in a place where the actual
818 value does not matter.
819 (LIST_END_P): Remove unused macro and its bogus comment.
820 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
822 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
823 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
825 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
826 We prefer signed types, and the value cannot exceed the EMACS_INT
827 range anyway (because otherwise the length would not be representable).
828 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
829 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
830 This avoids a GCC warning when WIDE_EMACS_INT.
832 * indent.c (sane_tab_width): New function.
833 (current_column, scan_for_column, Findent_to, position_indentation)
834 (compute_motion): Use it. This is just for clarity.
835 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
837 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
839 * lisp.h (lint_assume): New macro.
840 * composite.c (composition_gstring_put_cache):
841 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
843 * editfns.c, insdel.c:
844 Omit unnecessary forward decls, to simplify future changes.
846 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
848 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
850 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
851 Use much-faster test for byte-length change.
852 Don't assume string byte-length fits in 'int'.
853 Check that character arg fits in 'int'.
854 (mapcar1): Declare byte as byte, for clarity.
856 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
858 * fns.c (concat): Catch string overflow earlier.
859 Do not rely on integer wraparound.
861 * dispextern.h (struct it.overlay_strings_charpos)
862 (struct it.selective): Now EMACS_INT, not int.
863 * xdisp.c (forward_to_next_line_start)
864 (back_to_previous_visible_line_start)
865 (reseat_at_next_visible_line_start, next_element_from_buffer):
866 Don't arbitrarily truncate the value of 'selective' to int.
868 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
870 * composite.c: Don't truncate sizes to 'int'.
871 (composition_gstring_p, composition_reseat_it)
872 (composition_adjust_point): Use EMACS_INT, not int.
873 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
874 not EMACS_UINT, for indexes.
876 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
878 * buffer.c: Include <verify.h>.
879 (struct sortvec.priority, struct sortstr.priority):
880 Now EMACS_INT, not int.
881 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
882 (struct sortstr.size, record_overlay_string)
883 (struct sortstrlist.size, struct sortlist.used):
884 Don't truncate size to int.
885 (record_overlay_string): Check for size-calculation overflow.
886 (init_buffer_once): Check at compile-time, not run-time.
888 2011-06-22 Jim Meyering <meyering@redhat.com>
890 Don't leak an XBM-image-sized buffer
891 * image.c (xbm_load): Free the image buffer after using it.
893 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
896 * composite.c (find_automatic_composition): Omit needless 'return 0;'
897 that Sun C diagnosed.
898 * fns.c (secure_hash): Fix pointer signedness issue.
899 * intervals.c (static_offset_intervals): New function.
900 (offset_intervals): Use it.
902 2011-06-21 Leo Liu <sdl.web@gmail.com>
905 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
908 * fns.c (secure_hash): Rename from crypto_hash_function and change
909 the first arg to accept symbols.
910 (Fsecure_hash): New primitive.
911 (syms_of_fns): New symbols.
913 2011-06-20 Deniz Dogan <deniz@dogan.se>
915 * process.c (Fset_process_buffer): Clarify return value in
918 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
920 * dispnew.c (add_window_display_history): Use BVAR.
922 * xdisp.c (debug_method_add): Use BVAR.
923 (check_window_end, dump_glyph_matrix, dump_glyph)
924 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
926 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
929 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
930 check till after the cache is created in init_frame_faces.
932 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
934 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
936 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
938 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
939 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
940 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
942 Improve buffer-overflow checking (Bug#8873).
943 * fileio.c (Finsert_file_contents):
944 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
945 Remove the old (too-loose) buffer overflow checks.
946 They weren't needed, since make_gap checks for buffer overflow.
947 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
948 The old code merely checked for Emacs fixnum overflow, and relied
949 on undefined (wraparound) behavior. The new code avoids undefined
950 behavior, and also checks for ptrdiff_t and/or size_t overflow.
952 * editfns.c (Finsert_char): Don't dump core with very negative counts.
953 Tune. Don't use wider integers than needed. Don't use alloca.
954 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
956 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
958 * insdel.c, lisp.h (buffer_overflow): New function.
959 (insert_from_buffer_1, replace_range, replace_range_2):
960 * insdel.c (make_gap_larger):
961 * editfns.c (Finsert_char):
962 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
964 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
966 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
968 Integer overflow and signedness fixes (Bug#8873).
970 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
971 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
973 * fileio.c: Don't assume EMACS_INT fits in off_t.
974 (emacs_lseek): New static function.
975 (Finsert_file_contents, Fwrite_region): Use it.
976 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
978 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
980 * fns.c: Don't overflow int when computing a list length.
981 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
982 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
983 truncation on 64-bit hosts. Check for QUIT every
984 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
985 faster and is responsive enough.
986 (Flength): Report an error instead of overflowing an integer.
987 (Fsafe_length): Return a float if the value is not representable
988 as a fixnum. This shouldn't happen except in contrived situations.
989 (Fnthcdr, Fsort): Don't assume list length fits in int.
990 (Fcopy_sequence): Don't assume vector length fits in int.
992 * alloc.c: Check that resized vectors' lengths fit in fixnums.
993 (header_size, word_size): New constants.
994 (allocate_vectorlike): Don't check size overflow here.
995 (allocate_vector): Check it here instead, since this is the only
996 caller of allocate_vectorlike that could cause overflow.
997 Check that the new vector's length is representable as a fixnum.
999 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
1000 The previous code was bogus. For example, next_almost_prime (32)
1001 returned 39, which is undesirable as it is a multiple of 3; and
1002 next_almost_prime (24) returned 25, which is a multiple of 5 so
1003 why was the code bothering to check for multiples of 7?
1005 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
1007 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
1009 Variadic C functions now count arguments with ptrdiff_t.
1010 This partly undoes my 2011-03-30 change, which replaced int with size_t.
1011 Back then I didn't know that the Emacs coding style prefers signed int.
1012 Also, in the meantime I found a few more instances where arguments
1013 were being counted with int, which may truncate counts on 64-bit
1014 machines, or EMACS_INT, which may be unnecessarily wide.
1015 * lisp.h (struct Lisp_Subr.function.aMANY)
1016 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
1017 Arg counts are now ptrdiff_t, not size_t.
1018 All variadic functions and their callers changed accordingly.
1019 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
1020 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
1021 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
1022 * callint.c (Fcall_interactively): Check arg count for overflow,
1023 to avoid potential buffer overrun. Use signed char, not 'int',
1024 for 'varies' array, so that we needn't bother to check its size
1025 calculation for overflow.
1026 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
1027 * eval.c (apply_lambda):
1028 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
1029 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
1030 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
1032 * callint.c (Fcall_interactively): Don't use index var as event count.
1034 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
1035 * mem-limits.h (SIZE): Remove; no longer used.
1037 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
1039 Remove unnecessary casts.
1040 * xterm.c (x_term_init):
1041 * xfns.c (x_set_border_pixel):
1042 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
1043 These aren't needed now that we assume ANSI C.
1045 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
1046 It's more likely to cause problems (due to unsigned overflow)
1049 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
1051 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
1053 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
1055 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
1057 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
1059 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
1061 GLYPH_CODE_FACE returns EMACS_INT, not int.
1062 * dispextern.h (merge_faces):
1063 * xfaces.c (merge_faces):
1064 * xdisp.c (get_next_display_element, next_element_from_display_vector):
1065 Don't assume EMACS_INT fits in int.
1067 * character.h (CHAR_VALID_P): Remove unused parameter.
1068 * fontset.c, lisp.h, xdisp.c: All uses changed.
1070 * editfns.c (Ftranslate_region_internal): Omit redundant test.
1072 * fns.c (concat): Minor tuning based on overflow analysis.
1073 This doesn't fix any bugs. Use int to hold character, instead
1074 of constantly refetching from Emacs object. Use XFASTINT, not
1075 XINT, for value known to be a character. Don't bother comparing
1076 a single byte to 0400, as it's always less.
1078 * floatfns.c (Fexpt):
1079 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
1081 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
1084 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
1086 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
1087 Without this fix, on a 64-bit host (aset S 0 4294967386) would
1088 incorrectly succeed when S was a string, because 4294967386 was
1089 truncated before it was used.
1091 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
1092 Otherwise, an out-of-range integer could cause undefined behavior
1095 * composite.c: Use int, not EMACS_INT, for characters.
1096 (fill_gstring_body, composition_compute_stop_pos): Use int, not
1097 EMACS_INT, for values that are known to be in character range.
1098 This doesn't fix any bugs but is the usual style inside Emacs and
1099 may generate better code on 32-bit machines.
1101 Make sure a 64-bit char is never passed to ENCODE_CHAR.
1102 This is for reasons similar to the recent CHAR_STRING fix.
1103 * charset.c (Fencode_char): Check that character arg is actually
1104 a character. Pass an int to ENCODE_CHAR.
1105 * charset.h (ENCODE_CHAR): Verify that the character argument is no
1106 wider than 'int', as a compile-time check to prevent future regressions
1109 * character.c (char_string): Remove unnecessary casts.
1111 Make sure a 64-bit char is never passed to CHAR_STRING.
1112 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
1113 by silently ignoring the top 32 bits, allowing some values
1114 that were far too large to be valid characters.
1115 * character.h: Include <verify.h>.
1116 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
1117 arguments are no wider than unsigned, as a compile-time check
1118 to prevent future regressions in this area.
1120 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
1121 (Fsubst_char_in_region):
1123 * xdisp.c (decode_mode_spec_coding):
1124 Adjust to CHAR_STRING's new requirement.
1125 * editfns.c (Finsert_char, Fsubst_char_in_region):
1126 * fns.c (concat): Check that character args are actually
1127 characters. Without this test, these functions did the wrong
1128 thing with wildly out-of-range values on 64-bit hosts.
1130 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
1131 These casts should not be needed on 32-bit hosts, either.
1132 * keyboard.c (read_char):
1133 * lread.c (Fload): Remove casts to unsigned.
1135 * lisp.h (UNSIGNED_CMP): New macro.
1136 This fixes comparison bugs on 64-bit hosts.
1137 (ASCII_CHAR_P): Use it.
1138 * casefiddle.c (casify_object):
1139 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
1140 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
1141 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
1142 * dispextern.h (FACE_FROM_ID):
1143 * keyboard.c (read_char): Use UNSIGNED_CMP.
1145 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
1146 not to EMACS_INT, to avoid GCC warning.
1148 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
1150 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
1151 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
1152 isn't needed on 32-bit machines.
1154 * buffer.c (Fgenerate_new_buffer_name):
1155 Use EMACS_INT for count, not int.
1156 (advance_to_char_boundary): Return EMACS_INT, not int.
1158 * data.c (Qcompiled_function): Now static.
1160 * window.c (window_body_lines): Now static.
1162 * image.c (gif_load): Rename local to avoid shadowing.
1164 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
1165 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
1166 * alloc.c (make_save_value): Integer argument is now of type
1168 (mark_object): Use ptrdiff_t, not int.
1169 * lisp.h (pD): New macro.
1170 * print.c (print_object): Use it.
1172 * alloc.c: Use EMACS_INT, not int, to count objects.
1173 (total_conses, total_markers, total_symbols, total_vector_size)
1174 (total_free_conses, total_free_markers, total_free_symbols)
1175 (total_free_floats, total_floats, total_free_intervals)
1176 (total_intervals, total_strings, total_free_strings):
1177 Now EMACS_INT, not int. All uses changed.
1178 (Fgarbage_collect): Compute overall total using a double, so that
1179 integer overflow is less likely to be a problem. Check for overflow
1180 when converting back to an integer.
1181 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
1182 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
1183 These were 'int' variables that could overflow on 64-bit hosts;
1184 they were never used, so remove them instead of repairing them.
1185 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
1186 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
1187 Previously, this ceilinged at INT_MAX, but that doesn't work on
1189 (allocate_pseudovector): Don't use EMACS_INT when int would do.
1191 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
1192 (allocate_vectorlike): Check for ptrdiff_t overflow.
1193 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
1194 when a (possibly-narrower) signed value would do just as well.
1195 We prefer using signed arithmetic, to avoid comparison confusion.
1197 * alloc.c: Catch some string size overflows that we were missing.
1198 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
1199 for convenience in STRING_BYTES_MAX.
1200 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
1201 The definition here is exact; the one in lisp.h was approximate.
1202 (allocate_string_data): Check for string overflow. This catches
1203 some instances we weren't catching before. Also, it catches
1204 size_t overflow on (unusual) hosts where SIZE_MAX <= min
1205 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
1206 and ptrdiff_t and EMACS_INT are both 64 bits.
1208 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
1209 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
1210 * lisp.h (STRING_BYTES_BOUND): Renamed from STRING_BYTES_MAX.
1212 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
1214 * alloc.c (Fmake_string): Check for out-of-range init.
1216 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
1218 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
1220 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
1222 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
1223 xg_get_default_scrollbar_width.
1225 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
1226 (int_gtk_range_get_value): Move to the scroll bar part of the file.
1227 (style_changed_cb): Call update_theme_scrollbar_width and call
1228 x_set_scroll_bar_default_width and xg_frame_set_char_size for
1229 all frames (Bug#8505).
1230 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
1231 Call gtk_window_set_resizable if HAVE_GTK3.
1232 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
1233 and height if HAVE_GTK3 (Bug#8505).
1234 (scroll_bar_width_for_theme): New variable.
1235 (update_theme_scrollbar_width): New function.
1236 (xg_get_default_scrollbar_width): Move code to
1237 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
1238 (xg_initialize): Call update_theme_scrollbar_width.
1240 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
1242 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
1244 2011-06-12 Martin Rudalics <rudalics@gmx.at>
1246 * frame.c (make_frame): Call other_buffer_safely instead of
1249 * window.c (temp_output_buffer_show): Call display_buffer with
1250 second argument Vtemp_buffer_show_specifiers and reset latter
1251 immediately after the call.
1252 (Vtemp_buffer_show_specifiers): New variable.
1253 (auto_window_vscroll_p, next_screen_context_lines)
1254 (Vscroll_preserve_screen_position): Remove leading asterisks from
1257 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
1259 Fix minor problems found by GCC 4.6.0 static checking.
1260 * buffer.c (Qclone_number): Remove for now, as it's unused.
1261 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
1262 (record_buffer): Remove unused local.
1263 * frame.c (other_visible_frames, frame_buffer_list): Now static.
1264 (set_frame_buffer_list): Remove; unused.
1265 * frame.h (other_visible_frames): Remove decl.
1266 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
1267 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
1268 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
1270 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
1271 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
1272 Define only if HAVE_GPM.
1273 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
1274 (update_hints_inhibit): Remove; never set. All uses removed.
1275 * widgetprv.h (emacsFrameClassRec): Remove decl.

1277 wasn't returning anything.
1278 (compare_window_configurations): Remove unused locals.
1279 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
1280 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
1281 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
1282 the same widths as pointers. This follows up on the 2011-05-06 patch.
1283 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
1284 * xterm.h: Likewise.
1285 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.

1299 * window.c (delete_deletable_window): Re-add.
1300 (Fset_window_configuration): Rewrite to handle dead buffers and
1301 consequently deletable windows.
1302 (window_tree, Fwindow_tree): Remove. Supply functionality in
1304 (compare_window_configurations): Simplify code.
1306 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
1308 * image.c (imagemagick_load_image): Fix type mismatch.
1309 (Fimagemagick_types): Likewise.
1311 * window.h (replace_buffer_in_windows): Declare.
1313 2011-06-11 Martin Rudalics <rudalics@gmx.at>
1315 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
1316 Qclone_number. Remove external declaration of Qdelete_window.
1317 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
1319 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer): Run
1320 Qbuffer_list_update_hook if allowed.
1321 (Fother_buffer): Rewrite doc-string. Major rewrite for new
1322 buffer list implementation.
1323 (other_buffer_safely): New function.
1324 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
1325 calls to replace_buffer_in_windows and
1326 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
1328 (record_buffer): Inhibit quitting and rewrite using quittable
1329 functions. Run Qbuffer_list_update_hook if allowed.
1330 (Frecord_buffer, Funrecord_buffer): New functions.

1341 (replace_buffer_in_all_windows): Remove prototype.
1342 (replace_buffer_in_windows_safely): Add prototype.
1344 * window.c: Declare Qdelete_window static again. Move down
1345 declaration of select_count.
1346 (Fnext_window, Fprevious_window): Rewrite doc-strings.
1347 (Fother_window): Move to window.el.
1348 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
1349 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
1350 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
1352 (replace_buffer_in_windows): Implement by calling
1353 Qreplace_buffer_in_windows.
1354 (replace_buffer_in_all_windows): Remove with some functionality
1355 moved into replace_buffer_in_windows_safely.
1356 (replace_buffer_in_windows_safely): New function.
1357 (select_window_norecord, select_frame_norecord): Move in front
1358 of run_window_configuration_change_hook. Remove now obsolete
1360 (Fset_window_buffer): Rewrite doc-string. Call
1361 Qrecord_window_buffer.
1362 (keys_of_window): Move binding for other-window to window.el.
1364 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
1366 * dispextern.h (struct image): Replace data member, whose int_val
1367 and ptr_val fields were not used by anything, with a single
1370 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
1371 (gif_clear_image, gif_load, imagemagick_load_image)

1851 Without this change, the gnutls library would invoke malloc etc.
1852 directly, which causes problems on non-SYNC_INPUT hosts, and which
1853 runs afoul of improving memory_full behavior. (Bug#8761)
1854 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
1855 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
1856 xfree instead of the default malloc, realloc, free.
1857 (Fgnutls_boot): No need to check for memory allocation failure,
1858 since xmalloc does that for us.

1883 Check for overflow in vector size calculations.
1884 * ccl.c (ccl_driver):
1885 Check for overflow when converting EMACS_INT to int.
1886 * fns.c, image.c: Remove unnecessary static decls that would otherwise

1888 * fns.c (make_hash_table, maybe_resize_hash_table):
1889 Check for integer overflow with large hash tables.
1890 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
1891 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
1892 (SXHASH_REDUCE): New macro.
1893 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
1894 Use it instead of discarding useful hash info with large hash values.
1895 (sxhash_float): New function.
1896 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
1897 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
1898 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
1899 Rewrite to use FIXNUM_BITS, as this simplifies things.
1900 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
1901 Adjust signatures to match updated version of code.
1902 (consing_since_gc): Now EMACS_INT, since a single hash table can
1903 use more than INT_MAX bytes.
1905 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
1907 Make it possible to build with GCC-4.6+ -O2 -flto.
1909 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
1911 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
1913 * minibuf.c (get_minibuffer, read_minibuf_unwind):
1914 Call minibuffer-inactive-mode.
1916 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
1918 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
1919 Update dependencies.
1921 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1923 * data.c (init_data): Remove code for UTS, this system is not
1926 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1928 Don't force ./temacs to start in terminal mode.
1930 * frame.c (make_initial_frame): Initialize faces in all cases, not
1931 only when CANNOT_DUMP is defined.
1932 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
1934 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1936 * dispnew.c (add_window_display_history): Use const for the string
1937 pointer. Remove declaration, not needed.
1939 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
1941 Use 'inline', not 'INLINE'.
1942 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
1943 * alloc.c, fontset.c (INLINE): Remove.
1944 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
1945 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
1946 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
1947 * gmalloc.c (register_heapinfo): Use inline unconditionally.
1948 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
1950 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1952 Make it possible to run ./temacs.
1954 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
1955 syms_of_callproc does the same thing. Remove test for
1956 "initialized", do it in the caller.
1957 * emacs.c (main): Avoid calling set_initial_environment when dumping.
1959 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
1961 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
1962 (read_minibuf): Use get_minibuffer.
1963 (syms_of_minibuf): Use DEFSYM.
1964 (Qmetadata): New var.
1965 * data.c (Qbuffer): Don't make it static.
1966 (syms_of_data): Use DEFSYM.
1968 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
1970 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
1971 (CCL_CODE_MIN): New macro.
1973 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
1975 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
1977 * eval.c (Qdebug): Now static.
1978 * lisp.h (Qdebug): Remove decl. This reverts a part of the
1979 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
1980 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
1982 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
1984 * image.c: Various fixes to ImageMagick code comments.
1985 (Fimagemagick_types): Doc fix.
1987 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
1989 Minor fixes prompted by GCC 4.6.0 warnings.
1991 * xselect.c (converted_selections, conversion_fail_tag): Now static.
1993 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
1994 (x_clipboard_manager_save_all): Move extern decl to ...
1995 * xterm.h: ... here, so that it can be checked for consistency.
1997 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
1999 * xselect.c (x_clipboard_manager_save_frame)
2000 (x_clipboard_manager_save_all): New functions.
2001 (Fx_clipboard_manager_save): Lisp function deleted.
2003 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
2004 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
2006 * xterm.h: Update prototype.
2008 2011-05-28 William Xu <william.xwl@gmail.com>
2010 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
2013 2011-05-28 Jim Meyering <meyering@redhat.com>
2015 Avoid a sign-extension bug in crypto_hash_function.
2016 * fns.c (to_uchar): Define.
2017 (crypto_hash_function): Use it to convert some newly-signed
2018 variables to unsigned, to avoid sign-extension bugs. For example,
2019 without this change, (md5 "truc") would evaluate to
2020 45723a2aff78ff4fff7fff1114760e62 rather than the expected
2021 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
2022 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
2024 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
2026 Integer overflow fixes.
2028 * dbusbind.c: Serial number integer overflow fixes.
2029 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
2030 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
2031 to hold a serial number that is too large for a fixnum.
2032 (Fdbus_method_return_internal, Fdbus_method_error_internal):
2033 Check for serial numbers out of range. Decode any serial number
2034 that was so large that it became a float. (Bug#8722)
2036 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
2037 (Fdbus_call_method, Fdbus_call_method_asynchronously):
2038 Use XFASTINT rather than XUINT when numbers are nonnegative.
2039 (xd_append_arg, Fdbus_method_return_internal):
2040 (Fdbus_method_error_internal): Likewise. Also, for unsigned
2041 arguments, check that Lisp number is nonnegative, rather than
2042 silently wrapping negative numbers around. (Bug#8722)
2043 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
2046 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
2048 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
2050 ccl: add integer overflow checks
2051 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
2052 (IN_INT_RANGE): New macros.
2053 (ccl_driver): Use them to check for integer overflow when
2054 decoding a CCL program. Many of the new checks are whether XINT (x)
2055 fits in int; it doesn't always, on 64-bit hosts. The new version
2056 doesn't catch all possible integer overflows, but it's an
2057 improvement. (Bug#8719)
2059 * alloc.c (make_event_array): Use XINT, not XUINT.
2060 There's no need for unsigned here.
2062 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
2063 This follows up to the 2011-05-06 change that substituted uintptr_t
2064 for EMACS_INT. This case wasn't caught back then.
2066 Rework Fformat to avoid integer overflow issues.
2067 * editfns.c: Include <float.h> unconditionally, as it's everywhere
2068 now (part of C89). Include <verify.h>.
2069 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
2070 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
2071 (Fformat): Avoid the prepass trying to compute sizes; it was only
2072 approximate and thus did not catch overflow reliably. Instead, walk
2073 through the format just once, formatting and computing sizes as we go,
2074 checking for integer overflow at every step, and allocating a larger
2075 buffer as needed. Keep track separately whether the format is
2076 multibyte. Keep only the most-recently calculated precision, rather
2077 than them all. Record whether each argument has been converted to
2078 string. Use EMACS_INT, not int, for byte and char and arg counts.
2079 Support field widths and precisions larger than INT_MAX. Avoid
2080 sprintf's undefined behavior with conversion specifications such as %#d
2081 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
2082 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
2083 formatting out-of-range floating point numbers with int
2086 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
2088 * data.c: Avoid integer truncation in expressions involving floats.
2089 * data.c: Include <intprops.h>.
2090 (arith_driver): When there's an integer overflow in an expression
2091 involving floating point, convert the integers to floating point
2092 so that the resulting value does not suffer from catastrophic
2093 integer truncation. For example, on a 64-bit host (* 4
2094 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
2095 Do not rely on undefined behavior after integer overflow.
2097 merge count_size_as_multibyte, parse_str_to_multibyte
2098 * character.c, character.h (count_size_as_multibyte):
2099 Rename from parse_str_to_multibyte; all uses changed.
2100 Check for integer overflow.
2101 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
2102 since it's now a duplicate of the other. This is more of
2103 a character than a buffer op, so better that it's in character.c.
2104 * fns.c, print.c: Adjust to above changes.
2106 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
2108 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
2110 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
2112 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
2113 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
2114 (x_clipboard_manager_save): Now static.
2115 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
2117 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
2118 (crypto_hash_function): Now static.
2119 Fix pointer signedness problems. Avoid unnecessary initializations.
2121 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
2123 * termhooks.h (Vselection_alist): Make it terminal-local.
2125 * terminal.c (create_terminal): Initialize it.
2127 * xselect.c: Support for clipboard managers.
2128 (Vselection_alist): Move to termhooks.h as terminal-local var.
2129 (LOCAL_SELECTION): New macro.
2130 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
2131 (symbol_to_x_atom): Remove gratuitous arg.
2132 (x_handle_selection_request, lisp_data_to_selection_data)
2133 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
2134 (x_own_selection, x_get_local_selection, x_convert_selection):
2135 New arg, specifying work frame. Use terminal-local Vselection_alist.
2136 (some_frame_on_display): Delete unused function.
2137 (Fx_own_selection_internal, Fx_get_selection_internal)
2138 (Fx_disown_selection_internal, Fx_selection_owner_p)
2139 (Fx_selection_exists_p): New optional frame arg.
2140 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
2141 (x_handle_selection_clear): Don't treat other terminals with the
2142 same keyboard specially. Use the terminal-local Vselection_alist.
2143 (x_clear_frame_selections): Use Frun_hook_with_args.
2145 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
2147 * xterm.h: Add support for those atoms.
2149 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
2151 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
2152 (converted_selections, conversion_fail_tag): New global variables.
2153 (x_selection_request_lisp_error): Free the above.
2154 (x_get_local_selection): Remove unnecessary code.
2155 (x_reply_selection_request): Args changed; handle arbitrary array
2156 of converted selections stored in converted_selections.
2157 Separate the XChangeProperty and SelectionNotify steps.
2158 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
2159 (x_convert_selection): New function.
2160 (x_handle_selection_event): Simplify.
2161 (x_get_foreign_selection): Don't ignore incoming requests while
2162 waiting for an answer; this will fail when we implement
2163 SAVE_TARGETS, and seems unnecessary anyway.
2164 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
2165 (Vx_sent_selection_functions): Doc fix.
2167 2011-05-26 Leo Liu <sdl.web@gmail.com>
2169 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
2171 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2173 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
2175 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
2176 for fringe update if it has periodic bitmap.
2177 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
2178 and fringe_bitmap_periodic_p.
2180 * fringe.c (get_fringe_bitmap_data): New function.
2181 (draw_fringe_bitmap_1, update_window_fringes): Use it.
2182 (update_window_fringes): Record periodicity of fringe bitmap in glyph
2183 row. Mark glyph row for fringe update if periodicity changed.
2185 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
2186 for fringe update unless it has periodic bitmap.
2188 2011-05-25 Kenichi Handa <handa@m17n.org>
2190 * xdisp.c (get_next_display_element): Set correct it->face_id for
2191 a static composition.
2193 2011-05-24 Leo Liu <sdl.web@gmail.com>
2196 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
2198 * fns.c (crypto_hash_function, Fsha1): New function.
2199 (Fmd5): Use crypto_hash_function.
2200 (syms_of_fns): Add Ssha1.
2202 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
2204 * gnutls.c: Remove unused macros.
2205 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
2206 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
2207 Remove macros that are defined and never used.
2208 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
2210 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
2212 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
2213 (Fx_get_selection_internal): Minor cleanup.
2214 (Fx_own_selection_internal): Rename arguments for consistency with
2217 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
2219 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
2221 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
2223 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
2225 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2227 * dispnew.c (scrolling_window): Don't exclude the case that the
2228 last enabled row in the desired matrix touches the bottom boundary.
2230 2011-05-21 Glenn Morris <rgm@gnu.org>
2232 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
2233 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
2234 and add some more files.
2236 2011-05-20 Eli Zaretskii <eliz@gnu.org>
2238 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
2239 report_file_error introduced by the change from 2011-05-07.
2241 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
2243 * systime.h (Time): Define only if emacs is defined.
2244 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
2245 where the include path doesn't have X11/X.h by default. See
2246 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
2248 2011-05-20 Kenichi Handa <handa@m17n.org>
2250 * composite.c (find_automatic_composition): Fix previous change.
2252 2011-05-20 Glenn Morris <rgm@gnu.org>
2254 * lisp.mk: New file, split from Makefile.in.
2255 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
2256 (shortlisp): Remove.
2257 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
2259 2011-05-19 Glenn Morris <rgm@gnu.org>
2261 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
2262 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
2263 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
2264 (lisp): Set the order to that of loadup.el.
2265 (shortlisp): Make it a copy of $lisp.
2266 (SOME_MACHINE_LISP): Remove.
2267 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
2268 Use just $shortlisp, not $SOME_MACHINE_LISP too.
2270 2011-05-18 Kenichi Handa <handa@m17n.org>
2272 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
2273 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
2274 (find_automatic_composition): Mostly rewrite for efficiency.
2276 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
2278 * makefile.w32-in: Update dependencies.
2280 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
2282 * menu.c: Include limits.h (fixes the MS-Windows build broken by
2283 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
2285 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
2287 Fix some integer overflow issues, such as string length overflow.
2289 * insdel.c (count_size_as_multibyte): Check for string overflow.
2291 * character.c (lisp_string_width): Check for string overflow.
2292 Use EMACS_INT, not int, for string indexes and lengths; in
2293 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
2294 the resulting string length overflows an EMACS_INT; instead,
2295 report a string overflow if no precision given. When checking for
2296 precision exhaustion, use a check that cannot possibly have
2297 integer overflow. (Bug#8675)
2298 * character.h (lisp_string_width): Adjust to new signature.
2300 * alloc.c (string_overflow): New function.
2301 (Fmake_string): Use it. This doesn't change behavior, but saves
2302 a few bytes and will simplify future changes.
2303 * character.c (string_escape_byte8): Likewise.
2304 * lisp.h (string_overflow): New decl.
2306 Fixups, following up to the user-interface timestamp change.
2307 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
2308 for UI timestamps, instead of unsigned long.
2309 * msdos.c (mouse_get_pos): Likewise.
2310 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
2311 * w32gui.h (Time): Define by including "systime.h" rather than by
2312 declaring it ourselves. (Bug#8664)
2314 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
2315 * image.c (clear_image_cache): Likewise.
2317 * term.c (term_mouse_position): Don't assume time_t wraparound.
2319 Be more systematic about user-interface timestamps.
2320 Before, the code sometimes used 'Time', sometimes 'unsigned long',
2321 and sometimes 'EMACS_UINT', to represent these timestamps.
2322 This change causes it to use 'Time' uniformly, as that's what X uses.
2323 This makes the code easier to follow, and makes it easier to catch
2324 integer overflow bugs such as Bug#8664.
2325 * frame.c (Fmouse_position, Fmouse_pixel_position):
2326 Use Time, not unsigned long, for user-interface timestamps.
2327 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
2328 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
2329 * keyboard.h (last_event_timestamp): Likewise.
2330 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
2331 * menu.h (xmenu_show): Likewise.
2332 * term.c (term_mouse_position): Likewise.
2333 * termhooks.h (struct input_event.timestamp): Likewise.
2334 (struct terminal.mouse_position_hook): Likewise.
2335 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
2336 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
2337 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
2338 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
2340 * menu.h, termhooks.h: Include "systime.h", for Time.
2342 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
2343 Don't assume that the difference between two unsigned long values
2344 can fit into an integer. At this point, we know button_down_time
2345 <= event->timestamp, so the difference must be nonnegative, so
2346 there's no need to cast the result if double-click-time is
2347 nonnegative, as it should be; check that it's nonnegative, just in
2348 case. This bug is triggered when events are more than 2**31 ms
2349 apart (about 25 days). (Bug#8664)
2351 * xselect.c (last_event_timestamp): Remove duplicate decl.
2352 (x_own_selection): Remove needless cast to unsigned long.
2354 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
2355 that always fit in int. Use a sentinel instead of a counter, to
2356 avoid a temp and to allay GCC's concerns about possible int overflow.
2357 * frame.h (struct frame): Use int for menu_bar_items_used
2358 instead of EMACS_INT, since it always fits in int.
2360 * menu.c (grow_menu_items): Check for int overflow.
2362 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
2364 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
2365 Before, the code was not consistent. These values cannot exceed
2366 2**31 - 1 so there's no need to make them unsigned.
2367 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
2368 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
2369 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
2371 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
2373 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
2374 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
2375 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
2376 presumably because the widths might not match.
2378 * window.c (size_window): Avoid needless test at loop start.
2380 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
2382 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
2384 2011-05-12 Drew Adams <drew.adams@oracle.com>
2386 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
2388 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2390 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
2391 `width' to `bar_area_x' and `bar_area_width', respectively.
2392 (x_scroll_run): Take account of fringe background extension.
2394 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
2395 Rename local vars `left' and `width' to `bar_area_x' and
2396 `bar_area_width', respectively.
2397 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
2398 background extension.
2400 2011-05-10 Jim Meyering <meyering@redhat.com>
2402 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
2404 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
2406 * image.c (Finit_image_library): Return t for built-in image types,
2407 like pbm and xbm. (Bug#8640)
2409 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
2411 * w32menu.c (set_frame_menubar): Fix submenu allocation.
2413 2011-05-07 Eli Zaretskii <eliz@gnu.org>
2415 * w32console.c (Fset_screen_color): Doc fix.
2416 (Fget_screen_color): New function.
2417 (syms_of_ntterm): Defsubr it.
2419 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
2420 unlink the temporary file if Fcall_process didn't create it in the
2422 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
2423 child process will be redirected to a file specified with `:file'.
2424 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
2425 cue to call_process_cleanup not to close that handle.
2427 2011-05-07 Ben Key <bkey76@gmail.com>
2429 * makefile.w32-in: The bootstrap-temacs rule now makes use of
2430 one of two shell specific rules, either bootstrap-temacs-CMD or
2431 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
2432 to the previous implementation of the bootstrap-temacs rule.
2433 The bootstrap-temacs-CMD rule is similar to the previous
2434 implementation of the bootstrap-temacs rule except that it
2435 makes use of the ESC_CFLAGS variable instead of the CFLAGS
2438 These changes, along with some changes to nt/configure.bat,
2439 nt/gmake.defs, and nt/nmake.defs, are required to extend my
2440 earlier fix to add support for --cflags and --ldflags options
2441 that include quotes so that it works whether make uses cmd or
2444 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
2446 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
2447 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
2449 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
2450 a string. Handle both cases.
2451 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
2452 (Fdbus_register_method): Use Qinvalid_function.
2454 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
2456 * makefile.w32-in: Update dependencies.
2457 (LISP_H): Add inttypes.h and stdin.h.
2458 (PROCESS_H): Add unistd.h.
2460 2011-05-06 Eli Zaretskii <eliz@gnu.org>
2462 * lread.c: Include limits.h (fixes the MS-Windows build broken by
2463 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
2465 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
2467 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
2469 * term.c (vfatal): Remove stray call to va_end.
2470 It's not needed and the C Standard doesn't allow it here anyway.
2472 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
2473 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
2475 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
2478 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
2480 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
2482 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
2484 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
2486 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
2488 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
2489 * charset.c (Fdefine_charset_internal): Don't initialize
2490 charset.code_space[15]. The value was garbage, on hosts with
2491 32-bit int (Bug#8600).
2493 * lread.c (read_integer): Be more consistent with string-to-number.
2494 Use string_to_number to do the actual conversion; this avoids
2495 rounding errors and fixes some other screwups. Without this fix,
2496 for example, #x1fffffffffffffff was misread as -2305843009213693952.
2497 (digit_to_number): Move earlier, for benefit of read_integer.
2498 Return -1 if the digit is out of range for the base, -2 if it is
2499 not a digit in any supported base. (Bug#8602)
2501 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
2503 * dispnew.c (scrolling_window): Return 1 if we scrolled,
2504 to match comment at start of function. This also removes a
2505 GCC warning about overflow in a 32+64-bit port.
2507 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
2509 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
2510 Reported by Stefan Monnier in
2511 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
2512 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
2513 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
2515 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
2516 (EMACS_UINTPTR): Likewise, with uintptr_t.
2518 * lisp.h: Prefer 64-bit EMACS_INT if available.
2519 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
2520 on 32-bit hosts that have 64-bit int, so that they can access
2522 However, temporarily disable this change unless the temporary
2523 symbol WIDE_EMACS_INT is defined.
2525 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
2527 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
2528 This removes an assumption that EMACS_INT and long are the same
2529 width as pointers. The assumption is true for Emacs porting targets
2530 now, but we want to make other targets possible.
2531 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
2532 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
2533 In the rest of the code, change types of integers that hold casted
2534 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
2535 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
2536 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
2537 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
2538 No need to cast type when ORing.
2539 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
2540 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
2541 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
2542 assume EMACS_INT is the same width as char *.
2543 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
2544 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
2545 Remove no-longer-needed casts.
2546 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
2547 (xg_tool_bar_help_callback, xg_make_tool_item):
2548 Use EMACS_INTPTR to hold an integer
2549 that will be cast to void *; this can avoid a GCC warning
2550 if EMACS_INT is not the same width as void *.
2551 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
2552 * xdisp.c (display_echo_area_1, resize_mini_window_1):
2553 (current_message_1, set_message_1):
2554 Use a local to convert to proper width without a cast.
2555 * xmenu.c (dialog_selection_callback): Likewise.
2557 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
2558 Also, don't assume VALBITS / RAND_BITS is less than 5,
2559 and don't rely on undefined behavior when shifting a 1 left into
2561 * lisp.h (get_random): Change signature to match.
2563 * lread.c (hash_string): Use size_t, not int, for hash computation.
2564 Normally we prefer signed values; but hashing is special, because
2565 it's better to use unsigned division on hash table sizes so that
2566 the remainder is nonnegative. Also, size_t is the natural width
2567 for hashing into memory. The previous code used 'int', which doesn't
2568 retain enough info to hash well into very large tables.
2569 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
2571 * dbusbind.c: Don't possibly lose pointer info when converting.
2572 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
2573 Use XPNTR rather than XHASH, so that the high-order bits of
2574 the pointer aren't lost when converting through void *.
2576 * eval.c (Fautoload): Don't double-shift a pointer.
2578 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
2580 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
2582 * gnutls.c (DEF_GNUTLS_FN):
2583 * image.c (DEF_IMGLIB_FN): Make function pointers static.
2585 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
2587 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
2590 2011-05-05 Eli Zaretskii <eliz@gnu.org>
2592 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
2593 New version that can reserve upto 2GB of heap space.
2595 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
2597 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
2599 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
2601 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
2602 `gnutls_certificate_set_x509_key_file'.
2604 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
2606 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
2607 Update dependencies.
2609 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
2611 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
2612 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
2613 Remove unused parameter `fildes'.
2614 * process.c (read_process_output, send_process): Don't pass it.
2616 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
2618 Fix previous change: the library cache is defined in w32.c.
2619 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
2620 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
2622 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
2624 Implement dynamic loading of GnuTLS on Windows.
2626 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
2627 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
2628 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
2631 * gnutls.c (Qgnutls_dll): Define.
2632 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
2633 (gnutls_*): Declare function pointers.
2634 (init_gnutls_functions): New function to initialize function pointers.
2635 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
2636 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
2637 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
2638 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
2639 (emacs_gnutls_write, emacs_gnutls_read)
2640 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
2641 (Fgnutls_available_p): New function.
2642 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
2643 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
2644 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
2646 * image.c: Include w32.h.
2647 (Vimage_type_cache): Delete.
2648 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
2649 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
2650 (w32_delayed_load): Move to w32.c.
2652 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
2654 * w32.c (QCloaded_from, Vlibrary_cache): Define.
2655 (w32_delayed_load): Move from image.c. When loading a library, record
2656 its filename in the :loaded-from property of the library id.
2657 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
2658 Initialize and staticpro them.
2659 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
2661 * process.c: Include lisp.h before w32.h, not after.
2662 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
2663 instead of gnutls_record_check_pending.
2665 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
2667 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
2669 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
2670 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
2673 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
2675 * xterm.c (x_set_frame_alpha): Do not set property on anything
2676 else than FRAME_X_OUTER_WINDOW (Bug#8608).
2678 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
2680 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)

2691 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
2692 (Qgnutls_bootprop_callbacks_verify): Make static.
2694 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
2696 * callproc.c: Indentation fixup.
2698 * sysdep.c (wait_for_termination_1): Make static.
2699 (wait_for_termination, interruptible_wait_for_termination):
2700 Move after wait_for_termination_1.
2702 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
2704 * sysdep.c (interruptible_wait_for_termination): New function
2705 which is like wait_for_termination, but allows keyboard
2708 * callproc.c (Fcall_process): Add (:file "file") as an option for
2710 (Fcall_process_region): Ditto.
2712 2011-04-30 Eli Zaretskii <eliz@gnu.org>
2714 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
2715 rather than `XVECTOR (FOO)->size'.
2717 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
2718 inttypes.h, as a gnulib replacement is used if it not available in
2721 2011-04-21 Eli Zaretskii <eliz@gnu.org>
2723 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
2724 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
2725 of MOST_POSITIVE_FIXNUM. (Bug#8528)
2727 * coding.c (coding_alloc_by_realloc): Error out if destination
2728 will grow beyond MOST_POSITIVE_FIXNUM.
2729 (decode_coding_emacs_mule): Abort if there isn't enough place in
2730 charbuf for the composition carryover bytes. Reserve an extra
2731 space for up to 2 characters produced in a loop.
2732 (decode_coding_iso_2022): Abort if there isn't enough place in
2733 charbuf for the composition carryover bytes.
2735 2011-04-21 Eli Zaretskii <eliz@gnu.org>
2737 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
2738 aborting when %lld or %lll format is passed.

2748 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
2750 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
2751 (SIZE_MAX): Move defn after all includes, as they might #define it.
2753 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
2755 * w32.c (init_environment): Warn about defaulting HOME to C:\.
2757 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
2759 * keyboard.c (Qdelayed_warnings_hook): Define.
2760 (command_loop_1): Run `delayed-warnings-hook'
2761 if Vdelayed_warnings_list is non-nil.
2762 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
2763 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
2765 2011-04-28 Eli Zaretskii <eliz@gnu.org>
2767 * doprnt.c (doprnt): Don't return value smaller than the buffer
2768 size if the message was truncated. (Bug#8545).

2779 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
2781 * makefile.w32-in: Update dependencies.
2783 2011-04-27 Eli Zaretskii <eliz@gnu.org>
2785 Improve `doprnt' and its usage. (Bug#8545)
2786 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
2787 `format_end'. Remove support for %l as a conversion specifier.
2788 Don't use xrealloc. Improve diagnostics when the %l size modifier
2789 is used. Update the commentary.
2791 * eval.c (verror): Simplify calculation of size_t.
2793 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
2796 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
2798 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
2801 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
2803 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
2804 This makes this file independent of the recent pseudovector change.
2806 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
2808 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
2810 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
2811 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
2812 Remove unused local.
2813 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
2815 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
2816 GCC 4.6.0 optimizes based on type-based alias analysis.
2817 For example, if b is of type struct buffer * and v of type struct
2818 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
2819 != &v->size, and therefore "v->size = 1; b->size = 2; return
2820 v->size;" must therefore return 1. This assumption is incorrect
2821 for Emacs, since it type-puns struct Lisp_Vector * with many other
2822 types. To fix this problem, this patch adds a new type struct
2823 vectorlike_header that documents the constraints on layout of vectors
2824 and pseudovectors, and helps optimizing compilers not get fooled
2825 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
2826 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
2827 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
2829 (XSETPVECTYPE): Rewrite in terms of new macro.
2830 (XSETPVECTYPESIZE): New macro, specifying both type and size.
2831 This is a bit clearer, and further avoids the possibility of
2832 undesirable aliasing.
2833 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
2834 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
2835 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
2836 since Lisp_Subr is a special case (no "next" field).
2837 (ASIZE): Now uses header.size rather than size.
2838 All previous uses of XVECTOR (foo)->size replaced to use this macro,
2839 to avoid the hassle of writing XVECTOR (foo)->header.size.
2840 (struct vectorlike_header): New type.
2841 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
2842 object, to help avoid aliasing.
2843 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
2844 (SUBRP): Likewise, since Lisp_Subr is a special case.
2845 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
2846 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
2847 (struct Lisp_Hash_Table): Combine first two members into a single
2848 struct vectorlike_header member. All uses of "size" and "next" members
2849 changed to be "header.size" and "header.next".
2850 * buffer.h (struct buffer): Likewise.
2851 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
2852 * frame.h (struct frame): Likewise.
2853 * process.h (struct Lisp_Process): Likewise.
2854 * termhooks.h (struct terminal): Likewise.
2855 * window.c (struct save_window_data, struct saved_window): Likewise.
2856 * window.h (struct window): Likewise.
2857 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
2858 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
2859 * buffer.c (init_buffer_once): Likewise.
2860 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
2862 * process.c (Fformat_network_address): Use local var for size,
2865 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
2867 Make the Lisp reader and string-to-float more consistent (Bug#8525)
2868 * data.c (atof): Remove decl; no longer used or needed.
2869 (digit_to_number): Move to lread.c.
2870 (Fstring_to_number): Use new string_to_number function, to be
2871 consistent with how the Lisp reader treats infinities and NaNs.
2872 Do not assume that floating-point numbers represent EMACS_INT
2873 without losing information; this is not true on most 64-bit hosts.
2874 Avoid double-rounding errors, by insisting on integers when
2875 parsing non-base-10 numbers, as the documentation specifies.
2876 * lisp.h (string_to_number): New decl, replacing ...
2877 (isfloat_string): Remove.
2878 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
2879 (read1): Do not accept +. and -. as integers; this
2880 appears to have been a coding error. Similarly, do not accept
2881 strings like +-1e0 as floating point numbers. Do not report
2882 overflow for integer overflows unless the base is not 10 which
2883 means we have no simple and reliable way to continue.
2884 Break out the floating-point parsing into a new
2885 function string_to_number, so that Fstring_to_number parses
2886 floating point numbers consistently with the Lisp reader.
2887 (digit_to_number): Move here from data.c. Make it static inline.
2888 (E_CHAR, EXP_INT): Remove, replacing with ...
2889 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
2890 (string_to_number): New function, replacing isfloat_string.
2891 This function checks for valid syntax and produces the resulting
2892 Lisp float number too. Rework it so that string-to-number
2893 no longer mishandles examples like "1.0e+". Use strtoumax,
2894 so that overflow for non-base-10 numbers is reported only when
2895 there's no portable and simple way to convert to floating point.
2897 * textprop.c (set_text_properties_1): Rewrite for clarity,
2898 and to avoid GCC warning about integer overflow.
2900 * intervals.h (struct interval): Use EMACS_INT for members
2901 where EMACS_UINT might cause problems. See
2902 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
2903 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
2904 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
2906 (offset_intervals): Tell GCC not to worry about length overflow
2907 when negating a negative length.
2909 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
2910 (overrun_check_free): Likewise.
2912 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
2913 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
2916 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
2917 (gnutls_make_error): Rename local to avoid shadowing.
2918 (gnutls_emacs_global_deinit): ifdef out; not used.
2919 (Fgnutls_boot): Use const for pointer to readonly storage.
2920 Comment out unused local. Fix pointer signedness problems.
2922 * lread.c (openp): Don't stuff size_t into an 'int'.
2923 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
2924 about possible signed overflow.
2926 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
2927 (GDK_KEY_g): Don't define if already defined.
2928 (xg_prepare_tooltip): Avoid pointer signedness problem.
2929 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
2931 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
2932 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
2934 * xfns.c (Fx_window_property): Simplify a bit,
2935 to make a bit faster and to avoid GCC 4.6.0 warning.
2936 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
2938 * fns.c (internal_equal): Don't assume size_t fits in int.
2940 * alloc.c (compact_small_strings): Tighten assertion a little.
2942 Replace pEd with more-general pI, and fix some printf arg casts.
2943 * lisp.h (pI): New macro, generalizing old pEd macro to other
2944 conversion specifiers. For example, use "...%"pI"d..." rather
2945 than "...%"pEd"...".
2946 (pEd): Remove. All uses replaced with similar uses of pI.
2947 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
2948 * alloc.c (check_pure_size): Don't overflow by converting size to int.
2949 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
2950 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
2951 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
2952 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
2953 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
2955 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
2956 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
2957 * print.c (safe_debug_print, print_object): Likewise.
2958 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
2960 Use pI instead of if-then-else-abort. Use %p to avoid casts,
2961 avoiding the 0 flag, which is not portable.
2962 * process.c (Fmake_network_process): Use pI to avoid cast.
2963 * region-cache.c (pp_cache): Likewise.
2964 * xdisp.c (decode_mode_spec): Likewise.
2965 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
2966 behavior on 64-bit hosts with printf arg.
2967 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
2968 (x_stop_queuing_selection_requests): Likewise.
2969 (x_get_window_property): Don't truncate byte count to an 'int'
2972 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
2973 here, since it parses constructs like leading '-' and spaces,
2974 which are not wanted; and it overflows with large numbers.
2975 Instead, simply match F[0-9]+, which is what is wanted anyway.
2977 * alloc.c: Remove unportable assumptions about struct layout.
2978 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
2979 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
2980 (allocate_vectorlike, make_pure_vector): Use the new macros,
2981 plus offsetof, to remove unportable assumptions about struct layout.
2982 These assumptions hold on all porting targets that I know of, but
2983 they are not guaranteed, they're easy to remove, and removing them
2984 makes further changes easier.
2986 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
2987 This doesn't fix a bug but makes the code clearer.
2988 (string_overrun_cookie): Now const. Use initializers that
2989 don't formally overflow signed char, to avoid warnings.
2990 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
2991 can cause Emacs to crash when string overrun checking is enabled.
2992 (allocate_buffer): Don't assume sizeof (struct buffer) is a
2993 multiple of sizeof (EMACS_INT); it need not be, if
2994 alignof(EMACS_INT) < sizeof (EMACS_INT).
2995 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
2997 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
2999 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.

3018 (check_string_free_list): Convert to standard C.
3020 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
3022 * w32.c (emacs_gnutls_push): Fix typo.
3024 2011-04-25 Eli Zaretskii <eliz@gnu.org>
3026 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
3027 "cast to pointer from integer of different size".
3029 Improve doprnt and its use in verror. (Bug#8545)
3030 * doprnt.c (doprnt): Document the set of format control sequences
3031 supported by the function. Use SAFE_ALLOCA instead of always
3034 * eval.c (verror): Don't limit the buffer size at size_max-1, that
3035 is one byte too soon. Don't use xrealloc; instead xfree and
3038 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
3040 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

3044 gnutls_global_initialized. Added internals for the
3045 :verify-hostname-error, :verify-error, and :verify-flags
3046 parameters of `gnutls-boot' and documented those parameters in the
3047 docstring. Start callback support.
3048 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
3049 unless a fatal error occurred. Call gnutls_alert_send_appropriate
3050 on error. Return error code.
3051 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
3052 (emacs_gnutls_read): Likewise.
3053 (Fgnutls_boot): Return handshake error code.

3122 * doprnt.c: Include limits.h.
3123 (SIZE_MAX): New macro.
3124 (doprnt): Return a size_t value. 2nd arg is now size_t.
3125 Many local variables are now size_t instead of int or unsigned.
3126 Improve overflow protection. Support `l' modifier for integer
3127 conversions. Support %l conversion. Don't assume an EMACS_INT
3128 argument for integer conversions and for %c.
3130 * lisp.h (doprnt): Restore prototype.
3132 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
3135 * Makefile.in (base_obj): Add back doprnt.o.
3137 * deps.mk (doprnt.o): Add back prerequisites.
3138 (callint.o): Depend on character.h.
3140 * eval.c (internal_lisp_condition_case): Include the handler
3141 representation in the error message.
3142 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
3143 when breaking from the loop.
3145 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
3147 * callint.c (Fcall_interactively): When displaying error message
3148 about invalid control letter, pass the character's codepoint, not
3149 a pointer to its multibyte form. Improve display of the character
3150 in octal and display also its hex code.
3152 * character.c (char_string): Use %x to display the (unsigned)
3153 codepoint of an invalid character, to avoid displaying a bogus
3156 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
3157 `error', not SYMBOL_NAME itself.
3159 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
3160 character arguments to `error'.
3162 * charset.c (check_iso_charset_parameter): Fix incorrect argument
3163 to `error' in error message about FINAL_CHAR argument. Make sure
3164 FINAL_CHAR is a character, and use %c when it is passed as
3165 argument to `error'.
3167 2011-04-23 Eli Zaretskii <eliz@gnu.org>
3169 * s/ms-w32.h (localtime): Redirect to sys_localtime.

3246 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
3247 so that we aren't warned about unused symbols.

3258 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
3259 (x_dispatch_event): Declare static if USE_GTK, and
3260 define if USE_GTK || USE_X_TOOLKIT.
3261 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
3262 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.
3263 * xterm.c, xterm.h (x_mouse_leave): Bring this function back, but only

3355 ns_descriptor_to_entity that were caused by using free to
3356 deallocate memory blocks that were allocated by xmalloc (via
3357 xstrdup). This caused Emacs to crash when compiled with
3358 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with

3377 (emacs_read, emacs_write): Use it.
3378 * process.c (send_process): Adjust to the new signatures of
3379 emacs_write and emacs_gnutls_write. Do not attempt to store

3725 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
3726 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
3728 alloc.c: Import and export fewer symbols, and remove unused items.
3729 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
3731 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
3732 it's not optimized away by whole-program optimization.
3733 (message_enable_multibyte, free_misc): Remove.
3734 (catchlist, handlerlist, mark_backtrace):
3735 Declare only if BYTE_MARK_STACK.
3736 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
3737 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
3738 (message_enable_multibyte): Remove decl.
3739 (free_misc, interval_free_list, float_block, float_block_index):
3740 (n_float_blocks, float_free_list, cons_block, cons_block_index):
3741 (cons_free_list, last_marked_index):
3743 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
3744 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
3745 (mark_backtrace): Define only if BYTE_MARK_STACK.
3746 * xdisp.c (message_enable_multibyte): Now static.
3748 Declare Lisp_Object Q* variables to be 'static' if not exported.
3749 This makes it easier for human readers (and static analyzers)
3750 to see whether these variables are used from other modules.
3751 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
3752 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
3753 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

3757 * xmenu.c, xselect.c:
3758 Declare Q* vars static if they are not used in other modules.
3759 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
3760 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
3761 Remove decls of unexported vars.
3762 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
3764 * lisp.h (DEFINE_FUNC): Make sname 'static'.
3766 Make Emacs functions such as Fatom 'static' by default.
3767 This makes it easier for human readers (and static analyzers)
3768 to see whether these functions can be called from other modules.
3769 DEFUN now defines a static function. To make the function external
3770 so that it can be used in other C modules, use the new macro DEFUE.
3771 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
3772 (Finit_image_library):
3773 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
3774 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
3775 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
3776 Remove decls, since these functions are now static.
3777 (Funintern, Fget_internal_run_time): New decls, since these functions
3778 were already external.
3780 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
3781 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
3782 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:

3784 * keyboard.c, keymap.c, lread.c:
3785 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
3786 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
3787 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
3788 Mark functions with DEFUE instead of DEFUN,
3789 if they are used in other modules.
3790 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
3791 decls for now-static functions.
3792 * buffer.h (Fdelete_overlay): Remove decl.
3793 * callproc.c (Fgetenv_internal): Mark as internal.
3794 * composite.c (Fremove_list_of_text_properties): Remove decl.

3805 (Fremove_list_of_text_properties): Remove decls.
3806 * keyboard.c (Fthis_command_keys): Remove decl.
3807 (Fcommand_execute): New forward static decl.
3808 * keymap.c (Flookup_key): New forward static decl.
3809 (Fcopy_keymap): Now static.
3810 * keymap.h (Flookup_key): Remove decl.
3811 * process.c (Fget_process): New forward static decl.
3812 (Fprocess_datagram_address): Mark as internal.
3813 * syntax.c (Fsyntax_table_p): New forward static decl.

3823 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
3825 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
3828 2011-04-13 Eli Zaretskii <eliz@gnu.org>
3830 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
3831 when at ZV. (Bug#8487)
3833 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
3835 * charset.c (Fclear_charset_maps): Use xfree instead of free.
3837 * keyboard.c (parse_tool_bar_item): Likewise.
3838 * sound.c (sound_cleanup, alsa_close): Likewise.
3839 * termcap.c (tgetent): Likewise.
3840 * xfns.c (x_default_font_parameter): Likewise.
3841 * xsettings.c (read_and_apply_settings): Likewise.
3843 * alloc.c (overrun_check_malloc, overrun_check_realloc)
3844 (overrun_check_free): Protoize.
3846 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
3848 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
3849 since callers should never pass a negative size.
3850 Change the signature to match that of plain 'read' and 'write'; see
3851 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
3852 * lisp.h: Update prototypes of emacs_write and emacs_read.
3854 2011-04-11 Eli Zaretskii <eliz@gnu.org>
3856 * xdisp.c (redisplay_window): Don't try to determine the character
3857 position of the scroll margin if the window start point w->startp
3858 is outside the buffer's accessible region. (Bug#8468)
3860 2011-04-10 Eli Zaretskii <eliz@gnu.org>
3862 Fix write-region and its subroutines for buffers > 2GB.
3863 * fileio.c (a_write, e_write): Modify declaration of arguments and
3864 local variables to support buffers larger than 2GB.
3865 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
3867 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
3868 argument, local variables, and return value.
3870 * lisp.h: Update prototypes of emacs_write and emacs_read.
3872 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
3874 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
3876 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
3878 Fix more problems found by GCC 4.6.0's static checks.
3880 * xdisp.c (vmessage): Use a better test for character truncation.
3882 * charset.c (load_charset_map): <, not <=, for optimization,
3883 and to avoid potential problems with integer overflow.
3884 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
3885 * casetab.c (set_identity, shuffle): Likewise.
3886 * editfns.c (Fformat): Likewise.
3887 * syntax.c (skip_chars): Likewise.
3889 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
3890 This also lets GCC 4.6.0 generate slightly better loop code.
3892 * callint.c (Fcall_interactively): <, not <=, for optimization.
3893 (Fcall_interactively): Count the number of arguments produced,
3894 not the number of arguments given. This is simpler and lets GCC
3895 4.6.0 generate slightly better code.
3897 * ftfont.c: Distingish more carefully between FcChar8 and char.
3898 The previous code passed unsigned char * to a functions like
3899 strlen and xstrcasecmp that expect char *, which does not
3900 conform to the C standard.
3901 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
3902 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
3903 char * when the C standard requires it.
3905 * keyboard.c (read_char): Remove unused var.
3907 * eval.c: Port to Windows vsnprintf (Bug#8435).
3909 (SIZE_MAX): Define if the headers do not.
3910 (verror): Do not give up if vsnprintf returns a negative count.
3911 Instead, grow the buffer. This ports to Windows vsnprintf, which
3912 does not conform to C99. Problem reported by Eli Zaretskii.
3913 Also, simplify the allocation scheme, by avoiding the need for
3914 calling realloc, and removing the ALLOCATED variable.
3916 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
3918 Remove invocations of doprnt, as Emacs now uses vsnprintf.
3919 But keep the doprint source code for now, as we might revamp it
3920 and use it again (Bug#8435).
3921 * lisp.h (doprnt): Remove.
3922 * Makefile.in (base_obj): Remove doprnt.o.
3923 * deps.mk (doprnt.o): Remove.
3925 error: Print 32- and 64-bit integers portably (Bug#8435).
3926 Without this change, on typical 64-bit hosts error ("...%d...", N)
3927 was used to print both 32- and 64-bit integers N, which relied on
3929 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
3931 * lisp.h (error, verror): Mark as printf-like functions.
3932 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
3933 Report overflow in size calculations when allocating printf buffer.
3934 Do not truncate output string at its first null byte.
3935 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
3936 Truncate the output at a character boundary, since vsnprintf does not
3938 * charset.c (check_iso_charset_parameter): Convert internal
3939 character to string before calling 'error', since %c now has the
3941 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
3942 overflow when computing char to be passed to 'error'. Do not
3943 pass Lisp_Object to 'error'; pass the integer instead.
3944 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
3945 formatted with plain %d.
3947 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
3949 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
3951 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
3953 * xterm.c (x_catch_errors): Remove duplicate declaration.
3955 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
3957 * xdisp.c, lisp.h (message_nolog): Remove; unused.
3959 2011-04-10 Jim Meyering <meyering@redhat.com>
3961 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
3962 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
3963 return ssize_t not "int", and use size_t as the buffer length.
3964 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
3965 * gnutls.h: Update declarations.
3966 * process.c (read_process_output): Use ssize_t, to match.
3967 (send_process): Likewise.
3969 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
3971 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
3973 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
3975 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
3976 Use unsigned char, to match FcChar8 type definition.
3978 * xterm.c (handle_one_xevent):
3979 * xmenu.c (create_and_show_popup_menu):
3980 * xselect.c (x_decline_selection_request)
3981 (x_reply_selection_request): Avoid type-punned deref of X events.
3983 2011-04-09 Eli Zaretskii <eliz@gnu.org>
3985 Fix some uses of `int' instead of EMACS_INT.
3986 * search.c (string_match_1, fast_string_match)
3987 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
3988 (scan_buffer, find_next_newline_no_quit)
3989 (find_before_next_newline, search_command, Freplace_match)
3990 (Fmatch_data): Make some `int' variables be EMACS_INT.
3992 * xdisp.c (display_count_lines): 3rd argument and return value now
3993 EMACS_INT. All callers changed.
3994 (pint2hrstr): Last argument is now EMACS_INT.
3996 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
3997 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
3998 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
3999 (decode_coding_utf_16, decode_coding_emacs_mule)
4000 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
4001 (decode_coding_ccl, decode_coding_charset)
4002 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
4003 (decode_coding_iso_2022, decode_coding_emacs_mule)
4004 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
4005 <char_offset, last_offset>: Declare EMACS_INT.
4006 (encode_coding_utf_8, encode_coding_utf_16)
4007 (encode_coding_emacs_mule, encode_invocation_designation)
4008 (encode_designation_at_bol, encode_coding_iso_2022)
4009 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
4010 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
4012 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
4013 (encode_invocation_designation): Last argument P_NCHARS is now
4015 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
4016 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
4018 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
4021 * ccl.c (Fccl_execute_on_string): Declare some variables
4024 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)

4032 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
4034 * xml.c (parse_region): Avoid creating spurious whiespace nodes.
4036 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
4038 * keyboard.c (read_char): Call Lisp function help-form-show,
4039 instead of using internal_with_output_to_temp_buffer.
4040 (Qhelp_form_show): New var.
4041 (syms_of_keyboard): Use DEFSYM macro.
4043 * print.c (internal_with_output_to_temp_buffer): Function deleted.
4045 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
4047 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
4049 * process.c (Flist_processes): Remove to Lisp.
4050 (list_processes_1): Delete.

4056 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
4058 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
4060 Fix more problems found by GCC 4.6.0's static checks.
4062 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
4064 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
4066 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
4068 * xdisp.c (vmessage): Mark as a printf-like function.
4070 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
4072 * sound.c (sound_warning): Don't crash if arg contains a printf format.
4074 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
4075 printf-like functions.
4076 (tiff_load): Add casts to remove these marks before passing them
4077 to system-supplied API.
4079 * eval.c (Fsignal): Remove excess argument to 'fatal'.
4081 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
4082 This avoids several warnings with gcc -Wstrict-overflow.
4083 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
4084 directly, rather than having caller test rule sign. This avoids
4085 some unnecessary tests.
4086 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
4087 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
4088 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
4090 * xfont.c (xfont_text_extents): Remove var that was set but not used.
4091 (xfont_open): Avoid unnecessary tests.
4093 * composite.c (composition_gstring_put_cache): Use unsigned integer.

4096 Use EMACS_INT, not int, for length.
4098 * composite.h (COMPOSITION_DECODE_REFS): New macro,
4099 breaking out part of COMPOSITION_DECODE_RULE.
4100 (COMPOSITION_DECODE_RULE): Use it.
4101 * composite.c (get_composition_id): Remove unused local vars,
4102 by using the new macro.
4104 * textprop.c (set_text_properties_1): Change while to do-while,
4105 since the condition is always true at first.
4107 * intervals.c (graft_intervals_into_buffer): Mark var as used.
4108 (interval_deletion_adjustment): Return unsigned value.
4111 * process.c (list_processes_1, create_pty, read_process_output):
4112 (exec_sentinel): Remove vars that were set but not used.
4113 (create_pty): Remove unnecessary "volatile"s.

4120 * syntax.c (scan_words): Remove var that was set but not used.
4121 (update_syntax_table): Use unsigned instead of int.
4123 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.

4125 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
4127 * print.c (print_error_message): Avoid int overflow.
4129 * font.c (font_list_entities): Redo for clarity,
4130 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
4132 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
4133 (font_score): Avoid potential overflow in diff calculation.
4135 * fns.c (substring_both): Remove var that is set but not used.
4136 (sxhash): Redo loop for clarity and to avoid wraparound warning.
4138 * eval.c (funcall_lambda): Rename local to avoid shadowing.
4140 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
4141 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
4142 can always succeed if overflow has undefined behavior.
4144 * search.c (boyer_moore, wordify): Remove vars set but not used.
4145 (wordify): Omit three unnecessary tests.
4147 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
4148 All callers changed. This avoids the need for an unused var.
4150 * casefiddle.c (casify_region): Remove var that is set but not used.
4152 * dired.c (file_name_completion): Remove var that is set but not used.
4154 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
4156 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
4157 (Finsert_file_contents): Remove unnecessary code checking fd.
4159 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
4160 Check for integer overflow on size calculations.
4162 * buffer.c (Fprevious_overlay_change): Remove var that is set
4165 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
4166 Remove vars that are set but not used.
4167 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
4168 (timer_check_2): Mark vars as initialized.
4170 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
4172 * image.c (lookup_image): Remove var that is set but not used.
4173 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
4175 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
4176 that are set but not used.
4178 * xfns.c (make_invisible_cursor): Don't return garbage
4179 if XCreateBitmapFromData fails (Bug#8410).
4181 * xselect.c (x_get_local_selection, x_handle_property_notify):
4182 Remove vars that are set but not used.
4184 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
4185 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
4187 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
4188 Remove var that is set but not used.
4189 (scroll_bar_windows_size): Now size_t, not int.
4190 (x_send_scroll_bar_event): Use size_t, not int, for sizes.

4199 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
4200 All callers changed.
4201 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):

4203 (decode_coding_charset): Remove vars that are set but not used.
4205 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
4206 that is set but not used.
4208 * print.c (print_object): Remove var that is set but not used.
4210 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
4211 The gnulib version avoids calling malloc in the usual case,
4212 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
4213 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
4214 * filelock.c (current_lock_owner): Likewise.
4215 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
4216 * sysdep.c: Include allocator.h, careadlinkat.h.

4239 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
4240 and thereabouts. All callers changed.
4241 (get_per_char_metric): Remove parameter `f', unused since
4242 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

4254 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
4256 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
4259 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
4261 Add lexical binding.
4263 * window.c (Ftemp_output_buffer_show): New fun.
4264 (Fsave_window_excursion):
4265 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
4267 * lread.c (lisp_file_lexically_bound_p): New function.
4268 (Fload): Bind Qlexical_binding.
4269 (readevalloop): Remove `evalfun' arg.
4270 Bind Qinternal_interpreter_environment.
4271 (Feval_buffer): Bind Qlexical_binding.
4272 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
4274 (syms_of_lread): Declare `lexical-binding'.
4276 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
4278 * keyboard.c (eval_dyn): New fun.
4279 (menu_item_eval_property): Use it.
4281 * image.c (parse_image_spec): Use Ffunctionp.
4283 * fns.c (concat, mapcar1): Accept byte-code-functions.
4285 * eval.c (Fsetq): Handle lexical vars.
4286 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
4287 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
4288 (FletX, Flet): Obey lexical binding.
4289 (Fcommandp): Handle closures.
4290 (Feval): New `lexical' arg.
4291 (eval_sub): New function extracted from Feval. Use it almost
4292 everywhere where Feval was used. Look up vars in lexical env.
4294 (Ffunctionp): Move from subr.el.
4295 (Ffuncall): Handle closures.
4296 (apply_lambda): Remove `eval_flags'.
4297 (funcall_lambda): Handle closures and new byte-code-functions.
4298 (Fspecial_variable_p): New function.
4299 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
4300 but without exporting it to Lisp.
4302 * doc.c (Fdocumentation, store_function_docstring):
4303 * data.c (Finteractive_form): Handle closures.
4305 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
4308 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
4310 (exec_byte_code): New function extracted from Fbyte_code to handle new
4311 calling convention for byte-code-functions. Add new byte-codes.

4319 * xdisp.c (redisplay_internal): Fix prototype.
4321 2011-03-31 Eli Zaretskii <eliz@gnu.org>
4323 * xdisp.c (SCROLL_LIMIT): New macro.
4324 (try_scrolling): Use it when setting scroll_limit.
4325 Limit scrolling to 100 screen lines.
4326 (redisplay_window): Even when falling back on "recentering",
4327 position point in the window according to scroll-conservatively,
4328 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
4330 (try_scrolling): When point is above the window, allow searching
4331 as far as scroll_max, or one screenful, to compute vertical
4332 distance from PT to the scroll margin position. This prevents
4333 try_scrolling from unnecessarily failing when
4334 scroll-conservatively is set to a value slightly larger than the
4335 window height. Clean up the case of PT below the margin at bottom
4336 of window: scroll_max can no longer be INT_MAX. When aggressive
4337 scrolling is in use, don't let point enter the opposite scroll
4338 margin as result of the scroll.
4339 (syms_of_xdisp) <scroll-conservatively>: Document the
4340 threshold of 100 lines for never-recentering scrolling.

4347 (message_log_check_duplicate): Remove parameters `prev_bol' and
4348 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
4349 (redisplay_internal): Remove parameter `preserve_echo_area',
4350 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
4352 * indent.c (Fvertical_motion):
4353 * window.c (window_scroll_pixel_based, Frecenter):
4354 Don't pass `need_y_p' to `move_it_by_lines'.
4356 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
4358 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
4359 steal a few bits to be more compact.
4360 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
4361 Remove unneeded casts.
4363 * bytecode.c (Fbyte_code): CAR and CDR can GC.
4365 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
4367 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
4368 binding" message (bug#7967).
4370 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
4372 Fix more problems found by GCC 4.6.0's static checks.
4374 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
4375 Remove unused local var.
4377 * editfns.c (Fmessage_box): Remove unused local var.
4379 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
4380 (note_mode_line_or_margin_highlight, note_mouse_highlight):
4381 Omit unused local vars.
4382 * window.c (shrink_windows): Omit unused local var.
4383 * menu.c (digest_single_submenu): Omit unused local var.
4384 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
4385 Omit unused local var.
4387 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
4388 Don't assume string length fits in int.
4389 (keyremap_step, read_key_sequence): Use size_t for sizes.
4390 (read_key_sequence): Don't check last_real_key_start redundantly.
4392 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
4393 instead of alloca (Bug#8344).
4395 * eval.c (Fbacktrace): Don't assume nargs fits in int.
4396 (Fbacktrace_frame): Don't assume nframes fits in int.
4398 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

4405 * cm.c (calccost): Turn while-do into do-while, for clarity.
4407 * keyboard.c (syms_of_keyboard): Use the same style as later
4408 in this function when indexing through an array. This also
4409 works around GCC bug 48267.
4411 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
4413 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
4415 * chartab.c (sub_char_table_ref_and_range): Redo for slight
4416 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
4418 * keyboard.c, keyboard.h (num_input_events): Now size_t.
4419 This avoids undefined behavior on integer overflow, and is a bit
4420 more convenient anyway since it is compared to a size_t variable.
4422 Variadic C functions now count arguments with size_t, not int.
4423 This avoids an unnecessary limitation on 64-bit machines, which
4424 caused (substring ...) to crash on large vectors (Bug#8344).
4425 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.

4434 * fns.c (concat): Likewise.
4435 * frame.c (x_set_frame_parameters): Likewise.
4436 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
4437 0 if not found, not -1. All callers changed.
4439 * alloc.c (garbage_collect): Don't assume stack size fits in int.
4440 (stack_copy_size): Now size_t, not int.
4441 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
4443 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
4445 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
4446 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
4447 All callers changed.

4462 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
4463 don't set the hook to nil, but remove the offending function instead.
4464 (Qcommand_hook_internal): Remove, unused.
4465 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
4466 Vcommand_hook_internal.

4469 (funcall_nil, funcall_not): New functions.
4470 (run_hook_with_args): Call each function through a `funcall' argument.

4487 * w32.c (_wsa_errlist): Use braces for struct initializers.
4489 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
4490 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.

4493 used outside xdisp.c).

4560 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
4561 (gap_left, gap_right): Don't call it.
4563 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
4565 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
4566 incurred during fontification.

4634 2011-03-23 Julien Danjou <julien@danjou.info>
4636 * term.c (Fsuspend_tty, Fresume_tty):
4637 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
4638 * window.c (temp_output_buffer_show):
4639 * insdel.c (signal_before_change):
4640 * frame.c (Fhandle_switch_frame):
4641 * fileio.c (Fdo_auto_save):
4642 * emacs.c (Fkill_emacs):
4643 * editfns.c (save_excursion_restore):
4644 * cmds.c (internal_self_insert):
4645 * callint.c (Fcall_interactively):
4646 * buffer.c (Fkill_all_local_variables):
4647 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
4649 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
4650 unconditionnaly since it does the check itself.
4652 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
4654 Fix more problems found by GCC 4.5.2's static checks.
4656 * coding.c (encode_coding_raw_text): Avoid unnecessary test
4657 the first time through the loop, since we know p0 < p1 then.
4658 This also avoids a gcc -Wstrict-overflow warning.
4660 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
4661 leading to a memory leak, possible in functions like
4662 load_charset_map_from_file that can allocate an unbounded number
4663 of objects (Bug#8318).
4665 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
4666 that could (at least in theory) be that large.
4668 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
4669 This is less likely to overflow, and avoids undefined behavior if
4670 overflow does occur. All callers changed. Use strtoul to scan
4671 for the unsigned long integer.
4672 (pint2hrstr): Simplify and tune code slightly.
4673 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
4675 * scroll.c (do_scrolling): Work around GCC bug 48228.
4676 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
4678 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
4679 This also avoids a warning with gcc -Wstrict-overflow.
4680 (validate_x_resource_name): Simplify count usage.
4681 This also avoids a warning with gcc -Wstrict-overflow.
4683 * fileio.c (Fcopy_file): Report error if fchown or fchmod
4686 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
4688 * process.c (Fmake_network_process): Use socklen_t, not int,
4689 where POSIX says socklen_t is required in portable programs.
4690 This fixes a porting bug on hosts like 64-bit HP-UX, where
4691 socklen_t is wider than int (Bug#8277).
4692 (Fmake_network_process, server_accept_connection):
4693 (wait_reading_process_output, read_process_output):
4696 * process.c: Rename or move locals to avoid shadowing.

4702 (process_send_signal): Add cast to avoid pointer signedness problem.
4703 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
4704 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
4706 Make tparam.h and terminfo.c consistent.
4707 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
4708 Include tparam.h instead, since it declares them.
4709 * cm.h (PC): Remove extern decl; tparam.h now does this.
4710 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
4711 * terminfo.c: Include tparam.h, to check interfaces.
4712 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
4713 (tparam): Adjust signature to match interface in tparam.h;
4714 this removes some undefined behavior. Check that outstring and len
4715 are zero, which they always are with Emacs.
4716 * tparam.h (PC, BC, UP): New extern decls.
4718 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
4719 (xftfont_open): Rename locals to avoid shadowing.
4721 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
4722 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.

4737 (composition_update_it): Mark var as initialized.
4738 (find_automatic_composition): Mark vars as initialized,
4739 with a FIXME (Bug#8290).
4741 character.h: Rename locals to avoid shadowing.
4742 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
4743 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
4744 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
4745 (BUF_DEC_POS): Be more systematic about renaming local temporaries
4748 * textprop.c (property_change_between_p): Remove; unused.
4750 * intervals.c (interval_start_pos): Now static.
4752 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
4754 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
4755 Rename locals to avoid shadowing.
4757 * sound.c (wav_play, au_play, Fplay_sound_internal):
4758 Fix pointer signedness.
4759 (alsa_choose_format): Remove unused local var.
4760 (wav_play): Initialize a variable to 0, to prevent undefined
4761 behavior (Bug#8278).
4763 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
4765 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
4767 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
4768 clobbering (Bug#8298).
4769 * sysdep.c (sys_subshell): Likewise.
4770 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
4772 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
4773 This should get cleaned up, so that child_setup has the
4774 same signature on all platforms.
4776 * callproc.c (call_process_cleanup): Now static.
4777 (relocate_fd): Rename locals to avoid shadowing.
4779 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
4781 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
4782 not to be necessary, and produces flickering.
4784 2011-03-20 Glenn Morris <rgm@gnu.org>
4786 * config.in: Remove file.
4788 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
4790 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
4791 are now in src/globals.h.
4792 (syms_of_minibuf): Remove spurious & from previous change.
4794 2011-03-20 Leo <sdl.web@gmail.com>
4796 * minibuf.c (completing-read-function): New variable.
4797 (completing-read-default): Rename from completing-read.
4798 (completing-read): Call completing-read-function.
4800 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
4802 * xfaces.c (Fx_load_color_file):
4803 Read color file from absolute filename (bug#8250).
4805 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
4807 * makefile.w32-in: Update dependencies.
4809 2011-03-17 Eli Zaretskii <eliz@gnu.org>
4811 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.
4813 2011-03-17 Paul Eggert <eggert@cs.ucla.edu>
4815 Fix more problems found by GCC 4.5.2's static checks.

4818 (sigchld_handler): Now static.
4820 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
4821 That way, the code declares only the vars that it needs.
4822 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
4823 * s/cygwin.h (PTY_ITERATION): Likewise.
4824 * s/darwin.h (PTY_ITERATION): Likewise.
4825 * s/gnu-linux.h (PTY_ITERATION): Likewise.
4827 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
4828 * process.c (allocate_pty): Don't declare stb unless it's needed.
4830 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
4831 (CONSTANTLIM): Remove; unused.
4832 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
4833 Define only if needed.
4835 * unexelf.c (unexec): Name an expression,
4836 to avoid gcc -Wbad-function-cast warning.
4837 Use a different way to cause a compilation error if anyone uses
4838 n rather than nn, a way that does not involve shadowing.
4839 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
4841 * deps.mk (unexalpha.o): Remove; unused.
4843 New file unexec.h, the (simple) interface for unexec (Bug#8267).
4844 * unexec.h: New file.
4845 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
4846 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
4848 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
4849 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
4850 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
4851 Change as necessary to match prototype in unexec.h.

4855 (back_comment, skip_chars): Mark vars as initialized.
4857 * character.h (FETCH_STRING_CHAR_ADVANCE_NO_CHECK, BUF_INC_POS):
4858 Rename locals to avoid shadowing.
4860 * lread.c (read1): Rewrite so as not to use empty "else".
4861 (Fload, readevalloop, read1): Rename locals to avoid shadowing.
4863 * print.c (Fredirect_debugging_output): Fix pointer signedess.
4865 * lisp.h (debug_output_compilation_hack): Add decl here, to avoid
4866 warning when compiling print.c.
4868 * font.c (font_unparse_fcname): Abort in an "impossible" situation
4869 instead of using an uninitialized var.
4870 (font_sort_entities): Mark var as initialized.
4872 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
4874 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

4889 * alloc.c (mark_backtrace): Move decl from here ...
4890 * lisp.h: ... to here, so that it can be checked.
4892 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
4893 (Fdefvar): Rewrite so as not to use empty "else".

4904 * process.c (get_operating_system_release): Move decl to lisp.h.
4905 * xrdb.c (get_system_name): Likewise.
4906 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
4907 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
4908 some of which prompt warnings from gcc -Wbad-function-cast.
4909 (Fformat_time_string, Fencode_time, Finsert_char):
4910 (Ftranslate_region_internal, Fformat):
4911 Rename or remove local vars to avoid shadowing.

4921 gcc -Wbad-function-cast warning.
4922 (default_value, arithcompare, arith_driver, arith_error): Now static.

4929 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
4930 Rename locals to avoid shadowing.
4931 (mark_stack): Move local variables into the #ifdef region where
4933 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
4934 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
4936 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
4937 (GC_STRING_CHARS): Remove; not used.
4938 (Fmemory_limit): Cast sbrk's returned value to char *.
4940 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
4941 avoids undefined behavior in theory.
4943 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
4945 Use functions, not macros, for up- and down-casing (Bug#8254).
4946 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
4947 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
4948 to use the following functions instead of these macros.
4949 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
4950 EMACS_INT, since callers assume the returned value fits in int.
4951 (upcase1): Likewise, for UPCASE_TABLE.
4952 (uppercasep, lowercasep, upcase): New static inline functions.
4953 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

4958 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
4959 (regex_compile, re_search_2, re_match_2_internal):
4960 Remove unused local vars.
4961 (FREE_VAR): Rewrite so as not to use empty "else",
4962 which gcc can warn about.
4963 (regex_compile, re_match_2_internal): Mark locals as initialized.
4964 (RETALLOC_IF): Define only if needed.
4965 (WORDCHAR_P): Likewise. This one is never needed, but is used
4966 only in a comment talking about a compiler bug, so put inside
4967 the #if 0 of that comment.
4968 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
4969 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
4972 * search.c (boyer_moore): Rename locals to avoid shadowing.
4973 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
4974 (PREV_CHAR_BOUNDARY): Likewise.
4976 * search.c (simple_search): Remove unused var.
4978 * dired.c (compile_pattern): Move decl from here ...

4982 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
4984 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
4986 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):

4990 * casefiddle.c (casify_object, casify_region): Now static.
4991 (casify_region): Mark local as initialized.
4993 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
4995 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
4996 New macros, so that the caller can use some names other than
4997 gcpro1, gcpro2, etc.
4998 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
5000 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
5001 argument, for consistency with GCPRO2_VAR, etc: it is now the
5002 prefix of the variable, not the variable itself. All uses
5004 * dired.c (directory_files_internal, file_name_completion):
5005 Rename locals to avoid shadowing.
5007 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
5008 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
5009 dired.c's scmp function, had undefined behavior.
5010 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
5011 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
5012 * buffer.h: ... to here, because these macros use current_buffer,
5013 and the new implementation with inline functions needs to have
5014 current_buffer in scope now, rather than later when the macros
5016 (downcase, upcase1): New static inline functions.
5017 (DOWNCASE, UPCASE1): Reimplement using these functions.
5018 This avoids undefined behavior in expressions like
5019 DOWNCASE (x) == DOWNCASE (y), which previously suffered
5020 from race conditions in accessing the global variables
5021 case_temp1 and case_temp2.
5022 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
5023 * lisp.h (case_temp1, case_temp2): Remove their decls.
5024 * character.h (ASCII_CHAR_P): Move from here ...
5025 * lisp.h: ... to here, so that the inline functions mentioned
5028 * dired.c (directory_files_internal_unwind): Now static.
5030 * fileio.c (file_name_as_directory, directory_file_name):
5031 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
5033 (file_name_as_directory): Use const pointers when appropriate.
5034 (Fexpand_file_name): Likewise. In particular, newdir might
5035 point at constant storage, so make it a const pointer.
5036 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
5037 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
5039 (Fset_file_times, Finsert_file_contents, auto_save_error):
5040 Rename locals to avoid shadowing.
5042 * minibuf.c (choose_minibuf_frame_1): Now static.
5043 (Ftry_completion, Fall_completions): Rename or remove locals
5046 * marker.c (bytepos_to_charpos): Remove; unused.
5048 * lisp.h (verify_bytepos, count_markers): New decls,
5049 so that gcc does not warn that these functions aren't declared.
5051 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
5052 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
5053 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
5054 (copy_text): Remove unused local var.
5056 * filelock.c (within_one_second): Now static.
5057 (lock_file_1): Rename local to avoid shadowing.
5059 * buffer.c (fix_overlays_before): Mark locals as initialized.
5060 (fix_start_end_in_overlays): Likewise. This function should be
5061 simplified by using pointers-to-pointers, but that's a different
5063 (switch_to_buffer_1): Now static.
5064 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
5065 (report_overlay_modification): Rename locals to avoid shadowing.
5067 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
5068 Fix pointer signedness issue.
5069 (sys_subshell): Mark local as volatile if checking for lint,
5070 to suppress a gcc -Wclobbered warning that does not seem to be right.
5071 (MAXPATHLEN): Define only if needed.
5073 * process.c (serial_open, serial_configure): Move decls from here ...
5074 * systty.h: ... to here, so that they can be checked.
5076 * fns.c (get_random, seed_random): Move extern decls from here ...
5077 * lisp.h: ... to here, so that they can be checked.
5079 * sysdep.c (reset_io): Now static.
5080 (wait_for_termination_signal): Remove; unused.
5082 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

5085 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
5086 (DENSE_TABLE_SIZE): Remove; unused.
5087 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
5088 (describe_map_tree):
5089 Rename locals to avoid shadowing.
5091 * keyboard.c: Declare functions static if they are not used elsewhere.
5092 (echo_char, echo_dash, cmd_error, top_level_2):
5093 (poll_for_input, handle_async_input): Now static.
5094 (read_char, kbd_buffer_get_event, make_lispy_position):
5095 (make_lispy_event, make_lispy_movement, apply_modifiers):
5096 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
5097 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
5098 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
5099 (read_key_sequence, read_char): Mark locals as initialized.
5100 (Fexit_recursive_edit, Fabort_recursive_edit): Mark with NO_RETURN.
5102 * keyboard.h (make_ctrl_char): New decl.
5103 (mark_kboards): Move decl here ...
