3 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
4 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
5 well either way, and we prefer signed to unsigned.
7 Random fixes. E.g., (random) never returned negative values.
8 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9 subseconds part to the entropy, as that's a bit more random.
10 Prefer signed to unsigned, since the signedness doesn't matter and
11 in general we prefer signed. When given a limit, use a
12 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
13 latter isn't right if USE_2_TAGS_FOR_INTS.
14 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
15 not 0..VALMASK. Don't discard "excess" bits that random () returns.

23 * xfns.c (syms_of_xfns): Don't Add `display' since it's there by default.
25 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
27 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
28 This is more efficient than Ffile_directory_p and avoids a minor race.
30 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
32 * buffer.c (Foverlay_put): Say what the return value is
35 * fileio.c (barf_or_query_if_file_exists): Check first if the file
36 is a directory before asking whether to use the file name
38 (barf_or_query_if_file_exists): Make the "File is a directory"
39 error be more correct.
41 * fns.c (Frequire): Remove the mention of the .gz files, since
42 that's installation-specific, but keep the mention of
45 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>

58 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
59 Also (re)move comments that are misplaced or no longer relevant.
61 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>

155 (wait_reading_process_output): Add defined (HAVE_GSETTINGS) for
158 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
160 * eval.c (struct backtrace): Simplify and port the data structure.
161 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
162 signed bit field, as this assumption is not portable and it makes
163 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
164 "char debug_on_exit : 1" as this is not portable either; instead,
165 use the portable "unsigned int debug_on_exit : 1". Remove unused
166 member evalargs. Remove obsolete comments about cc bombing out.

347 Check for size-calculation overflow.
348 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
350 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
352 * lread.c: Integer overflow fixes.

400 (debug_method_add): Use va_list and vsprintf rather than relying
401 on undefined behavior with wrong number of arguments.
402 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
403 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
404 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
405 since we're not interested in debugging glyphs with old libraries.
406 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
407 GCC 4.6.0's static checking.
409 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

449 (x_session_initialize): Do not assume string length fits in int.
451 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
452 This is unlikely, but can occur if DPI is outlandish.

455 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
457 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.

489 Don't assume integer property fits in fixnum.
490 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
492 * filelock.c: Fix some buffer overrun and integer overflow issues.
493 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
494 Reformulate so as not to need the command string.
495 Invoke gzip -cd rather than gunzip, as it's more portable.
496 (lock_info_type, lock_file_1, lock_file):
497 Don't assume pid_t and time_t fit in unsigned long.
498 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
499 (current_lock_owner): Prefer signed type for sizes.
500 Use memcpy, not strncpy, where memcpy is what is really wanted.
501 Don't assume (via atoi) that time_t and pid_t fit in int.
502 Check for time_t and/or pid_t out of range, e.g., via a network share.
503 Don't alloca where an auto var works fine.
505 * fileio.c: Fix some integer overflow issues.
506 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
507 Don't assume string length fits in int.
508 (directory_file_name): Don't assume string length fits in long.
509 (make_temp_name): Don't assume pid fits in int, or that its print
510 length is less than 20.
512 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
514 * coding.c (make_subsidiaries): Don't assume string length fits in int.
516 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
518 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
519 We prefer signed integers, even for size calculations.
521 * emacs.c: Don't assume string length fits in 'int'.
522 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
523 (main): Don't invoke strlen when not needed.
525 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
526 (XD_DEBUG_MESSAGE): Don't waste a byte.
528 * callproc.c (getenv_internal_1, getenv_internal)
530 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
532 * lread.c (invalid_syntax): Omit length argument.
533 All uses changed. This doesn't fix a bug, but it simplifies the
534 code away from its former Hollerith-constant appearance, and it's
535 one less 'int' to worry about when looking at integer-overflow issues.
536 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
538 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
539 This didn't break anything, but it didn't help either.
540 It's confusing to put a bogus integer in a place where the actual
541 value does not matter.
542 (LIST_END_P): Remove unused macro and its bogus comment.
543 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
545 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
546 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
548 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
549 We prefer signed types, and the value cannot exceed the EMACS_INT
550 range anyway (because otherwise the length would not be representable).
551 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
552 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
553 This avoids a GCC warning when WIDE_EMACS_INT.
555 * indent.c (sane_tab_width): New function.
556 (current_column, scan_for_column, Findent_to, position_indentation)
557 (compute_motion): Use it. This is just for clarity.
558 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
560 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
562 * lisp.h (lint_assume): New macro.
563 * composite.c (composition_gstring_put_cache):
564 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
566 * editfns.c, insdel.c:
567 Omit unnecessary forward decls, to simplify future changes.
569 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
571 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
573 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
574 Use much-faster test for byte-length change.
575 Don't assume string byte-length fits in 'int'.
576 Check that character arg fits in 'int'.
577 (mapcar1): Declare byte as byte, for clarity.
579 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
581 * fns.c (concat): Catch string overflow earlier.
582 Do not rely on integer wraparound.
584 * dispextern.h (struct it.overlay_strings_charpos)
585 (struct it.selective): Now EMACS_INT, not int.
586 * xdisp.c (forward_to_next_line_start)
587 (back_to_previous_visible_line_start)
588 (reseat_at_next_visible_line_start, next_element_from_buffer):
589 Don't arbitrarily truncate the value of 'selective' to int.
591 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
593 * composite.c: Don't truncate sizes to 'int'.
594 (composition_gstring_p, composition_reseat_it)
595 (composition_adjust_point): Use EMACS_INT, not int.
596 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
597 not EMACS_UINT, for indexes.
599 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
601 * buffer.c: Include <verify.h>.
602 (struct sortvec.priority, struct sortstr.priority):
603 Now EMACS_INT, not int.
604 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
605 (struct sortstr.size, record_overlay_string)
606 (struct sortstrlist.size, struct sortlist.used):
607 Don't truncate size to int.
608 (record_overlay_string): Check for size-calculation overflow.
609 (init_buffer_once): Check at compile-time, not run-time.
611 2011-06-22 Jim Meyering <meyering@redhat.com>
613 Don't leak an XBM-image-sized buffer
614 * image.c (xbm_load): Free the image buffer after using it.
616 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
619 * composite.c (find_automatic_composition): Omit needless 'return 0;'
620 that Sun C diagnosed.
621 * fns.c (secure_hash): Fix pointer signedness issue.
622 * intervals.c (static_offset_intervals): New function.
623 (offset_intervals): Use it.
625 2011-06-21 Leo Liu <sdl.web@gmail.com>
628 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
631 * fns.c (secure_hash): Rename from crypto_hash_function and change
632 the first arg to accept symbols.
633 (Fsecure_hash): New primitive.
634 (syms_of_fns): New symbols.
636 2011-06-20 Deniz Dogan <deniz@dogan.se>
638 * process.c (Fset_process_buffer): Clarify return value in
641 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
643 * dispnew.c (add_window_display_history): Use BVAR.
645 * xdisp.c (debug_method_add): Use BVAR.
646 (check_window_end, dump_glyph_matrix, dump_glyph)
647 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
649 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
652 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
653 check till after the cache is created in init_frame_faces.
655 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
657 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
659 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
661 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
662 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
663 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
665 Improve buffer-overflow checking (Bug#8873).
666 * fileio.c (Finsert_file_contents):
667 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
668 Remove the old (too-loose) buffer overflow checks.
669 They weren't needed, since make_gap checks for buffer overflow.
670 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
671 The old code merely checked for Emacs fixnum overflow, and relied
672 on undefined (wraparound) behavior. The new code avoids undefined
673 behavior, and also checks for ptrdiff_t and/or size_t overflow.
675 * editfns.c (Finsert_char): Don't dump core with very negative counts.
676 Tune. Don't use wider integers than needed. Don't use alloca.
677 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
679 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
681 * insdel.c, lisp.h (buffer_overflow): New function.
682 (insert_from_buffer_1, replace_range, replace_range_2):
683 * insdel.c (make_gap_larger):
684 * editfns.c (Finsert_char):
685 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
687 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
689 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
691 Integer overflow and signedness fixes (Bug#8873).
693 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
694 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
696 * fileio.c: Don't assume EMACS_INT fits in off_t.
697 (emacs_lseek): New static function.
698 (Finsert_file_contents, Fwrite_region): Use it.
699 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
701 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
703 * fns.c: Don't overflow int when computing a list length.
704 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
705 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
706 truncation on 64-bit hosts. Check for QUIT every
707 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
708 faster and is responsive enough.
709 (Flength): Report an error instead of overflowing an integer.
710 (Fsafe_length): Return a float if the value is not representable
711 as a fixnum. This shouldn't happen except in contrived situations.
712 (Fnthcdr, Fsort): Don't assume list length fits in int.
713 (Fcopy_sequence): Don't assume vector length fits in int.
715 * alloc.c: Check that resized vectors' lengths fit in fixnums.
716 (header_size, word_size): New constants.
717 (allocate_vectorlike): Don't check size overflow here.
718 (allocate_vector): Check it here instead, since this is the only
719 caller of allocate_vectorlike that could cause overflow.
720 Check that the new vector's length is representable as a fixnum.
722 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
723 The previous code was bogus. For example, next_almost_prime (32)
724 returned 39, which is undesirable as it is a multiple of 3; and
725 next_almost_prime (24) returned 25, which is a multiple of 5 so
726 why was the code bothering to check for multiples of 7?
728 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
730 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
732 Variadic C functions now count arguments with ptrdiff_t.
733 This partly undoes my 2011-03-30 change, which replaced int with size_t.
734 Back then I didn't know that the Emacs coding style prefers signed int.
735 Also, in the meantime I found a few more instances where arguments
736 were being counted with int, which may truncate counts on 64-bit
737 machines, or EMACS_INT, which may be unnecessarily wide.
738 * lisp.h (struct Lisp_Subr.function.aMANY)
739 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
740 Arg counts are now ptrdiff_t, not size_t.
741 All variadic functions and their callers changed accordingly.
742 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
743 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
744 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
745 * callint.c (Fcall_interactively): Check arg count for overflow,
746 to avoid potential buffer overrun. Use signed char, not 'int',
747 for 'varies' array, so that we needn't bother to check its size
748 calculation for overflow.
749 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
750 * eval.c (apply_lambda):
751 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
752 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
753 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
755 * callint.c (Fcall_interactively): Don't use index var as event count.
757 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
758 * mem-limits.h (SIZE): Remove; no longer used.
760 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
762 Remove unnecessary casts.
763 * xterm.c (x_term_init):
764 * xfns.c (x_set_border_pixel):
765 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
766 These aren't needed now that we assume ANSI C.
768 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
769 It's more likely to cause problems (due to unsigned overflow)
772 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
774 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
776 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
778 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
780 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
782 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
784 GLYPH_CODE_FACE returns EMACS_INT, not int.
785 * dispextern.h (merge_faces):
786 * xfaces.c (merge_faces):
787 * xdisp.c (get_next_display_element, next_element_from_display_vector):
788 Don't assume EMACS_INT fits in int.
790 * character.h (CHAR_VALID_P): Remove unused parameter.
791 * fontset.c, lisp.h, xdisp.c: All uses changed.
793 * editfns.c (Ftranslate_region_internal): Omit redundant test.
795 * fns.c (concat): Minor tuning based on overflow analysis.
796 This doesn't fix any bugs. Use int to hold character, instead
797 of constantly refetching from Emacs object. Use XFASTINT, not
798 XINT, for value known to be a character. Don't bother comparing
799 a single byte to 0400, as it's always less.
801 * floatfns.c (Fexpt):
802 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
804 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
807 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
809 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
810 Without this fix, on a 64-bit host (aset S 0 4294967386) would
811 incorrectly succeed when S was a string, because 4294967386 was
812 truncated before it was used.
814 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
815 Otherwise, an out-of-range integer could cause undefined behavior
818 * composite.c: Use int, not EMACS_INT, for characters.
819 (fill_gstring_body, composition_compute_stop_pos): Use int, not
820 EMACS_INT, for values that are known to be in character range.
821 This doesn't fix any bugs but is the usual style inside Emacs and
822 may generate better code on 32-bit machines.
824 Make sure a 64-bit char is never passed to ENCODE_CHAR.
825 This is for reasons similar to the recent CHAR_STRING fix.
826 * charset.c (Fencode_char): Check that character arg is actually
827 a character. Pass an int to ENCODE_CHAR.
828 * charset.h (ENCODE_CHAR): Verify that the character argument is no
829 wider than 'int', as a compile-time check to prevent future regressions
832 * character.c (char_string): Remove unnecessary casts.
834 Make sure a 64-bit char is never passed to CHAR_STRING.
835 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
836 by silently ignoring the top 32 bits, allowing some values
837 that were far too large to be valid characters.
838 * character.h: Include <verify.h>.
839 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
840 arguments are no wider than unsigned, as a compile-time check
841 to prevent future regressions in this area.
843 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
844 (Fsubst_char_in_region):
846 * xdisp.c (decode_mode_spec_coding):
847 Adjust to CHAR_STRING's new requirement.
848 * editfns.c (Finsert_char, Fsubst_char_in_region):
849 * fns.c (concat): Check that character args are actually
850 characters. Without this test, these functions did the wrong
851 thing with wildly out-of-range values on 64-bit hosts.
853 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
854 These casts should not be needed on 32-bit hosts, either.
855 * keyboard.c (read_char):
856 * lread.c (Fload): Remove casts to unsigned.
858 * lisp.h (UNSIGNED_CMP): New macro.
859 This fixes comparison bugs on 64-bit hosts.
860 (ASCII_CHAR_P): Use it.
861 * casefiddle.c (casify_object):
862 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
863 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
864 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
865 * dispextern.h (FACE_FROM_ID):
866 * keyboard.c (read_char): Use UNSIGNED_CMP.
868 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
869 not to EMACS_INT, to avoid GCC warning.
871 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
873 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
874 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
875 isn't needed on 32-bit machines.
877 * buffer.c (Fgenerate_new_buffer_name):
878 Use EMACS_INT for count, not int.
879 (advance_to_char_boundary): Return EMACS_INT, not int.
881 * data.c (Qcompiled_function): Now static.
883 * window.c (window_body_lines): Now static.
885 * image.c (gif_load): Rename local to avoid shadowing.
887 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
888 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
889 * alloc.c (make_save_value): Integer argument is now of type
891 (mark_object): Use ptrdiff_t, not int.
892 * lisp.h (pD): New macro.
893 * print.c (print_object): Use it.
895 * alloc.c: Use EMACS_INT, not int, to count objects.
896 (total_conses, total_markers, total_symbols, total_vector_size)
897 (total_free_conses, total_free_markers, total_free_symbols)
898 (total_free_floats, total_floats, total_free_intervals)
899 (total_intervals, total_strings, total_free_strings):
900 Now EMACS_INT, not int. All uses changed.
901 (Fgarbage_collect): Compute overall total using a double, so that
902 integer overflow is less likely to be a problem. Check for overflow
903 when converting back to an integer.
904 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
905 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
906 These were 'int' variables that could overflow on 64-bit hosts;
907 they were never used, so remove them instead of repairing them.
908 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
909 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
910 Previously, this ceilinged at INT_MAX, but that doesn't work on
912 (allocate_pseudovector): Don't use EMACS_INT when int would do.
914 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
915 (allocate_vectorlike): Check for ptrdiff_t overflow.
916 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
917 when a (possibly-narrower) signed value would do just as well.
918 We prefer using signed arithmetic, to avoid comparison confusion.
920 * alloc.c: Catch some string size overflows that we were missing.
921 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
922 for convenience in STRING_BYTES_MAX.
923 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
924 The definition here is exact; the one in lisp.h was approximate.
925 (allocate_string_data): Check for string overflow. This catches
926 some instances we weren't catching before. Also, it catches
927 size_t overflow on (unusual) hosts where SIZE_MAX <= min
928 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
929 and ptrdiff_t and EMACS_INT are both 64 bits.
931 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
932 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
933 * lisp.h (STRING_BYTES_BOUND): Renamed from STRING_BYTES_MAX.
935 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
937 * alloc.c (Fmake_string): Check for out-of-range init.
939 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
941 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
943 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
945 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
946 xg_get_default_scrollbar_width.
948 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
949 (int_gtk_range_get_value): Move to the scroll bar part of the file.
950 (style_changed_cb): Call update_theme_scrollbar_width and call
951 x_set_scroll_bar_default_width and xg_frame_set_char_size for
952 all frames (Bug#8505).
953 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
954 Call gtk_window_set_resizable if HAVE_GTK3.
955 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
956 and height if HAVE_GTK3 (Bug#8505).
957 (scroll_bar_width_for_theme): New variable.
958 (update_theme_scrollbar_width): New function.
959 (xg_get_default_scrollbar_width): Move code to
960 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
961 (xg_initialize): Call update_theme_scrollbar_width.
963 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
965 * emacsgtkfixed.c, emacsgtkfixed.h: New files.

1437 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
1438 Do not assume that spare memory exists; that assumption is valid
1439 only if SYSTEM_MALLOC.
1440 (LARGE_REQUEST): New macro, so that the issue of large requests
1441 is separated from the issue of spare memory.
1443 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
1445 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

1457 * gtkutil.h: Declare xg_get_default_scrollbar_width.
1459 * xfns.c (x_set_scroll_bar_default_width): If USE_GTK, get
1460 min width by calling x_set_scroll_bar_default_width (Bug#8505).
1462 2011-06-05 Juanma Barranquero <lekktu@gmail.com>
1464 * xdisp.c (single_display_spec_intangible_p): Remove declaration.
1466 2011-06-04 Chong Yidong <cyd@stupidchicken.com>

1470 (x_clipboard_manager_error_1, x_clipboard_manager_error_2):
1472 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
1473 Obey Vx_select_enable_clipboard_manager. Catch errors in
1474 x_clipboard_manager_save (Bug#8779).
1475 (Vx_select_enable_clipboard_manager): New variable.
1476 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
1478 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
1480 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
1482 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1484 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
1485 in the current matrix if keep_current_p is non-zero.

1491 2011-06-03 Eli Zaretskii <eliz@gnu.org>
1493 Support bidi reordering of text covered by display properties.
1495 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
1496 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
1497 (bidi_cache_search, bidi_cache_iterator_state)
1498 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
1499 (bidi_level_of_next_char, bidi_move_to_visually_next):
1500 Support character positions inside a run of characters covered by a
1502 (bidi_paragraph_init, bidi_resolve_explicit_1)
1503 (bidi_level_of_next_char): Call bidi_fetch_char and
1504 bidi_fetch_char_advance instead of FETCH_CHAR and
1506 (bidi_init_it): Initialize new members.
1507 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
1509 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
1510 instead of using explicit *_CHAR codes.
1511 (bidi_resolve_explicit, bidi_resolve_weak):
1512 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
1513 bidirectional text is supported only in multibyte buffers.
1514 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
1515 it to initialize the frame_window_p member of struct bidi_it.
1516 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
1517 (bidi_resolve_explicit, bidi_resolve_weak)
1518 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
1519 bidi_it->nchars is non-positive.
1520 (bidi_level_of_next_char): Don't try to lookup the cache for the
1521 next/previous character if nothing is cached there yet, or if we
1522 were just reseat()'ed to a new position.
1524 * xdisp.c (set_cursor_from_row): Set start and stop points
1525 according to the row's direction when priming the loop that looks
1526 for the glyph on which to display cursor.
1527 (single_display_spec_intangible_p): Function deleted.
1528 (display_prop_intangible_p): Reimplement to call
1529 handle_display_spec instead of single_display_spec_intangible_p.
1530 Accept 3 additional arguments needed by handle_display_spec.
1531 This fixes incorrect cursor motion across display property with complex
1532 values: lists, `(when COND...)' forms, etc.
1533 (single_display_spec_string_p): Support property values that are
1534 lists with the argument STRING its top-level element.
1535 (display_prop_string_p): Fix the condition for processing a
1536 property that is a list to be consistent with handle_display_spec.
1537 (handle_display_spec): New function, refactored from the
1538 last portion of handle_display_prop.
1539 (compute_display_string_pos): Accept additional argument
1540 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
1541 value of a `display' property is a "replacing spec".
1542 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
1543 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
1544 the display property, but just return a value indicating whether
1545 the display property will replace the characters it covers.
1546 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
1547 frame_window_p members of struct bidi_it.
1548 (compute_display_string_pos, compute_display_string_end):
1550 (push_it): Accept second argument POSITION, where pop_it should
1551 jump to continue iteration.
1552 (reseat_1): Initialize bidi_it.disp_pos.
1554 * keyboard.c (adjust_point_for_property): Adjust the call to
1555 display_prop_intangible_p to its new signature.
1557 * dispextern.h (struct bidi_it): New member frame_window_p.
1558 (bidi_init_it): Update prototypes.
1559 (display_prop_intangible_p): Update prototype.
1560 (compute_display_string_pos, compute_display_string_end):
1562 (struct bidi_it): New members nchars and disp_pos. ch_len is now
1565 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
1567 Malloc failure behavior now depends on size of allocation.
1568 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
1569 * lisp.h: Change signatures accordingly.
1570 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
1571 All callers changed. (Bug#8762)
1573 * gnutls.c: Use Emacs's memory allocators.
1574 Without this change, the gnutls library would invoke malloc etc.
1575 directly, which causes problems on non-SYNC_INPUT hosts, and which
1576 runs afoul of improving memory_full behavior. (Bug#8761)
1577 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
1578 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
1579 xfree instead of the default malloc, realloc, free.
1580 (Fgnutls_boot): No need to check for memory allocation failure,
1581 since xmalloc does that for us.
1583 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
1584 * category.c (hash_get_category_set):
1585 * ccl.c (ccl_driver):
1586 * charset.c (Fdefine_charset_internal):
1587 * charset.h (struct charset.hash_index):
1588 * composite.c (get_composition_id, gstring_lookup_cache)
1589 (composition_gstring_put_cache):
1590 * composite.h (struct composition.hash_index):
1591 * dispextern.h (struct image.hash):
1592 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
1593 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
1594 (hashfn_equal, hashfn_user_defined, make_hash_table)
1595 (maybe_resize_hash_table, hash_lookup, hash_put)
1596 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
1597 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
1598 (Fsxhash, Fgethash, Fputhash, Fmaphash):
1599 * image.c (make_image, search_image_cache, lookup_image)
1600 (xpm_put_color_table_h):
1601 * lisp.h (struct Lisp_Hash_Table):
1602 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
1603 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
1604 for hashes and hash indexes, instead of 'unsigned' and 'int'.
1605 * alloc.c (allocate_vectorlike):
1606 Check for overflow in vector size calculations.
1607 * ccl.c (ccl_driver):
1608 Check for overflow when converting EMACS_INT to int.
1609 * fns.c, image.c: Remove unnecessary static decls that would otherwise
1610 need to be updated by these changes.
1611 * fns.c (make_hash_table, maybe_resize_hash_table):
1612 Check for integer overflow with large hash tables.
1613 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
1614 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
1615 (SXHASH_REDUCE): New macro.
1616 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
1617 Use it instead of discarding useful hash info with large hash values.
1618 (sxhash_float): New function.
1619 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
1620 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
1621 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
1622 Rewrite to use FIXNUM_BITS, as this simplifies things.
1623 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
1624 Adjust signatures to match updated version of code.
1625 (consing_since_gc): Now EMACS_INT, since a single hash table can
1626 use more than INT_MAX bytes.
1628 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
1630 Make it possible to build with GCC-4.6+ -O2 -flto.
1632 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
1634 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
1636 * minibuf.c (get_minibuffer, read_minibuf_unwind):
1637 Call minibuffer-inactive-mode.
1639 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
1641 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
1642 Update dependencies.
1644 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1646 * data.c (init_data): Remove code for UTS, this system is not
1649 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1651 Don't force ./temacs to start in terminal mode.
1653 * frame.c (make_initial_frame): Initialize faces in all cases, not
1654 only when CANNOT_DUMP is defined.
1655 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
1657 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1659 * dispnew.c (add_window_display_history): Use const for the string
1660 pointer. Remove declaration, not needed.
1662 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
1664 Use 'inline', not 'INLINE'.
1665 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
1666 * alloc.c, fontset.c (INLINE): Remove.
1667 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
1668 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
1669 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
1670 * gmalloc.c (register_heapinfo): Use inline unconditionally.
1671 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
1673 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1675 Make it possible to run ./temacs.
1677 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
1678 syms_of_callproc does the same thing. Remove test for
1679 "initialized", do it in the caller.
1680 * emacs.c (main): Avoid calling set_initial_environment when dumping.
1682 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
1684 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
1685 (read_minibuf): Use get_minibuffer.
1686 (syms_of_minibuf): Use DEFSYM.
1687 (Qmetadata): New var.
1688 * data.c (Qbuffer): Don't make it static.
1689 (syms_of_data): Use DEFSYM.
1691 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
1693 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
1694 (CCL_CODE_MIN): New macro.
1696 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
1698 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
1700 * eval.c (Qdebug): Now static.
1701 * lisp.h (Qdebug): Remove decl. This reverts a part of the
1702 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
1703 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
1705 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
1707 * image.c: Various fixes to ImageMagick code comments.
1708 (Fimagemagick_types): Doc fix.
1710 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
1712 Minor fixes prompted by GCC 4.6.0 warnings.
1714 * xselect.c (converted_selections, conversion_fail_tag): Now static.
1716 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
1717 (x_clipboard_manager_save_all): Move extern decl to ...
1718 * xterm.h: ... here, so that it can be checked for consistency.
1720 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
1722 * xselect.c (x_clipboard_manager_save_frame)
1723 (x_clipboard_manager_save_all): New functions.
1724 (Fx_clipboard_manager_save): Lisp function deleted.
1726 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
1727 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
1729 * xterm.h: Update prototype.
1731 2011-05-28 William Xu <william.xwl@gmail.com>
1733 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
1736 2011-05-28 Jim Meyering <meyering@redhat.com>
1738 Avoid a sign-extension bug in crypto_hash_function.
1739 * fns.c (to_uchar): Define.
1740 (crypto_hash_function): Use it to convert some newly-signed
1741 variables to unsigned, to avoid sign-extension bugs. For example,
1742 without this change, (md5 "truc") would evaluate to
1743 45723a2aff78ff4fff7fff1114760e62 rather than the expected
1744 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
1745 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
1747 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
1749 Integer overflow fixes.
1751 * dbusbind.c: Serial number integer overflow fixes.
1752 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
1753 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
1754 to hold a serial number that is too large for a fixnum.
1755 (Fdbus_method_return_internal, Fdbus_method_error_internal):
1756 Check for serial numbers out of range. Decode any serial number
1757 that was so large that it became a float. (Bug#8722)
1759 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
1760 (Fdbus_call_method, Fdbus_call_method_asynchronously):
1761 Use XFASTINT rather than XUINT when numbers are nonnegative.
1762 (xd_append_arg, Fdbus_method_return_internal):
1763 (Fdbus_method_error_internal): Likewise. Also, for unsigned
1764 arguments, check that Lisp number is nonnegative, rather than
1765 silently wrapping negative numbers around. (Bug#8722)
1766 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
1769 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
1771 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
1773 ccl: add integer overflow checks
1774 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
1775 (IN_INT_RANGE): New macros.
1776 (ccl_driver): Use them to check for integer overflow when
1777 decoding a CCL program. Many of the new checks are whether XINT (x)
1778 fits in int; it doesn't always, on 64-bit hosts. The new version
1779 doesn't catch all possible integer overflows, but it's an
1780 improvement. (Bug#8719)
1782 * alloc.c (make_event_array): Use XINT, not XUINT.
1783 There's no need for unsigned here.
1785 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
1786 This follows up to the 2011-05-06 change that substituted uintptr_t
1787 for EMACS_INT. This case wasn't caught back then.
1789 Rework Fformat to avoid integer overflow issues.
1790 * editfns.c: Include <float.h> unconditionally, as it's everywhere
1791 now (part of C89). Include <verify.h>.
1792 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
1793 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
1794 (Fformat): Avoid the prepass trying to compute sizes; it was only
1795 approximate and thus did not catch overflow reliably. Instead, walk
1796 through the format just once, formatting and computing sizes as we go,
1797 checking for integer overflow at every step, and allocating a larger
1798 buffer as needed. Keep track separately whether the format is
1799 multibyte. Keep only the most-recently calculated precision, rather
1800 than them all. Record whether each argument has been converted to
1801 string. Use EMACS_INT, not int, for byte and char and arg counts.
1802 Support field widths and precisions larger than INT_MAX. Avoid
1803 sprintf's undefined behavior with conversion specifications such as %#d
1804 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
1805 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
1806 formatting out-of-range floating point numbers with int
1809 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
1811 * data.c: Avoid integer truncation in expressions involving floats.
1812 * data.c: Include <intprops.h>.
1813 (arith_driver): When there's an integer overflow in an expression
1814 involving floating point, convert the integers to floating point
1815 so that the resulting value does not suffer from catastrophic
1816 integer truncation. For example, on a 64-bit host (* 4
1817 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
1818 Do not rely on undefined behavior after integer overflow.
1820 merge count_size_as_multibyte, parse_str_to_multibyte
1821 * character.c, character.h (count_size_as_multibyte):
1822 Rename from parse_str_to_multibyte; all uses changed.
1823 Check for integer overflow.
1824 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
1825 since it's now a duplicate of the other. This is more of
1826 a character than a buffer op, so better that it's in character.c.
1827 * fns.c, print.c: Adjust to above changes.
1829 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
1831 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
1833 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
1835 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
1836 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
1837 (x_clipboard_manager_save): Now static.
1838 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
1840 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
1841 (crypto_hash_function): Now static.
1842 Fix pointer signedness problems. Avoid unnecessary initializations.
1844 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
1846 * termhooks.h (Vselection_alist): Make it terminal-local.
1848 * terminal.c (create_terminal): Initialize it.
1850 * xselect.c: Support for clipboard managers.
1851 (Vselection_alist): Move to termhooks.h as terminal-local var.
1852 (LOCAL_SELECTION): New macro.
1853 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
1854 (symbol_to_x_atom): Remove gratuitous arg.
1855 (x_handle_selection_request, lisp_data_to_selection_data)
1856 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
1857 (x_own_selection, x_get_local_selection, x_convert_selection):
1858 New arg, specifying work frame. Use terminal-local Vselection_alist.
1859 (some_frame_on_display): Delete unused function.
1860 (Fx_own_selection_internal, Fx_get_selection_internal)
1861 (Fx_disown_selection_internal, Fx_selection_owner_p)
1862 (Fx_selection_exists_p): New optional frame arg.
1863 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
1864 (x_handle_selection_clear): Don't treat other terminals with the
1865 same keyboard specially. Use the terminal-local Vselection_alist.
1866 (x_clear_frame_selections): Use Frun_hook_with_args.
1868 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
1870 * xterm.h: Add support for those atoms.
1872 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
1874 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
1875 (converted_selections, conversion_fail_tag): New global variables.
1876 (x_selection_request_lisp_error): Free the above.
1877 (x_get_local_selection): Remove unnecessary code.
1878 (x_reply_selection_request): Args changed; handle arbitrary array
1879 of converted selections stored in converted_selections.
1880 Separate the XChangeProperty and SelectionNotify steps.
1881 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
1882 (x_convert_selection): New function.
1883 (x_handle_selection_event): Simplify.
1884 (x_get_foreign_selection): Don't ignore incoming requests while
1885 waiting for an answer; this will fail when we implement
1886 SAVE_TARGETS, and seems unnecessary anyway.
1887 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
1888 (Vx_sent_selection_functions): Doc fix.
1890 2011-05-26 Leo Liu <sdl.web@gmail.com>
1892 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
1894 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1896 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
1898 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
1899 for fringe update if it has periodic bitmap.
1900 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
1901 and fringe_bitmap_periodic_p.
1903 * fringe.c (get_fringe_bitmap_data): New function.
1904 (draw_fringe_bitmap_1, update_window_fringes): Use it.
1905 (update_window_fringes): Record periodicity of fringe bitmap in glyph
1906 row. Mark glyph row for fringe update if periodicity changed.
1908 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
1909 for fringe update unless it has periodic bitmap.
1911 2011-05-25 Kenichi Handa <handa@m17n.org>
1913 * xdisp.c (get_next_display_element): Set correct it->face_id for
1914 a static composition.
1916 2011-05-24 Leo Liu <sdl.web@gmail.com>
1919 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
1921 * fns.c (crypto_hash_function, Fsha1): New function.
1922 (Fmd5): Use crypto_hash_function.
1923 (syms_of_fns): Add Ssha1.
1925 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
1927 * gnutls.c: Remove unused macros.
1928 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
1929 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
1930 Remove macros that are defined and never used.
1931 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
1933 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
1935 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
1936 (Fx_get_selection_internal): Minor cleanup.
1937 (Fx_own_selection_internal): Rename arguments for consistency with
1940 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
1942 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
1944 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
1946 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
1948 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1950 * dispnew.c (scrolling_window): Don't exclude the case that the
1951 last enabled row in the desired matrix touches the bottom boundary.
1953 2011-05-21 Glenn Morris <rgm@gnu.org>
1955 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
1956 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
1957 and add some more files.
1959 2011-05-20 Eli Zaretskii <eliz@gnu.org>
1961 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
1962 report_file_error introduced by the change from 2011-05-07.
1964 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
1966 * systime.h (Time): Define only if emacs is defined.
1967 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
1968 where the include path doesn't have X11/X.h by default. See
1969 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
1971 2011-05-20 Kenichi Handa <handa@m17n.org>
1973 * composite.c (find_automatic_composition): Fix previous change.
1975 2011-05-20 Glenn Morris <rgm@gnu.org>
1977 * lisp.mk: New file, split from Makefile.in.
1978 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
1979 (shortlisp): Remove.
1980 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
1982 2011-05-19 Glenn Morris <rgm@gnu.org>
1984 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
1985 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
1986 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
1987 (lisp): Set the order to that of loadup.el.
1988 (shortlisp): Make it a copy of $lisp.
1989 (SOME_MACHINE_LISP): Remove.
1990 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
1991 Use just $shortlisp, not $SOME_MACHINE_LISP too.
1993 2011-05-18 Kenichi Handa <handa@m17n.org>
1995 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
1996 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
1997 (find_automatic_composition): Mostly rewrite for efficiency.
1999 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
2001 * makefile.w32-in: Update dependencies.
2003 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
2005 * menu.c: Include limits.h (fixes the MS-Windows build broken by
2006 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
2008 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
2010 Fix some integer overflow issues, such as string length overflow.
2012 * insdel.c (count_size_as_multibyte): Check for string overflow.
2014 * character.c (lisp_string_width): Check for string overflow.
2015 Use EMACS_INT, not int, for string indexes and lengths; in
2016 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
2017 the resulting string length overflows an EMACS_INT; instead,
2018 report a string overflow if no precision given. When checking for
2019 precision exhaustion, use a check that cannot possibly have
2020 integer overflow. (Bug#8675)
2021 * character.h (lisp_string_width): Adjust to new signature.
2023 * alloc.c (string_overflow): New function.
2024 (Fmake_string): Use it. This doesn't change behavior, but saves
2025 a few bytes and will simplify future changes.
2026 * character.c (string_escape_byte8): Likewise.
2027 * lisp.h (string_overflow): New decl.
2029 Fixups, following up to the user-interface timestamp change.
2030 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
2031 for UI timestamps, instead of unsigned long.
2032 * msdos.c (mouse_get_pos): Likewise.
2033 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
2034 * w32gui.h (Time): Define by including "systime.h" rather than by
2035 declaring it ourselves. (Bug#8664)
2037 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
2038 * image.c (clear_image_cache): Likewise.
2040 * term.c (term_mouse_position): Don't assume time_t wraparound.
2042 Be more systematic about user-interface timestamps.
2043 Before, the code sometimes used 'Time', sometimes 'unsigned long',
2044 and sometimes 'EMACS_UINT', to represent these timestamps.
2045 This change causes it to use 'Time' uniformly, as that's what X uses.
2046 This makes the code easier to follow, and makes it easier to catch
2047 integer overflow bugs such as Bug#8664.
2048 * frame.c (Fmouse_position, Fmouse_pixel_position):
2049 Use Time, not unsigned long, for user-interface timestamps.
2050 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
2051 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
2052 * keyboard.h (last_event_timestamp): Likewise.
2053 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
2054 * menu.h (xmenu_show): Likewise.
2055 * term.c (term_mouse_position): Likewise.
2056 * termhooks.h (struct input_event.timestamp): Likewise.
2057 (struct terminal.mouse_position_hook): Likewise.
2058 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
2059 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
2060 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
2061 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
2063 * menu.h, termhooks.h: Include "systime.h", for Time.
2065 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
2066 Don't assume that the difference between two unsigned long values
2067 can fit into an integer. At this point, we know button_down_time
2068 <= event->timestamp, so the difference must be nonnegative, so
2069 there's no need to cast the result if double-click-time is
2070 nonnegative, as it should be; check that it's nonnegative, just in
2071 case. This bug is triggered when events are more than 2**31 ms
2072 apart (about 25 days). (Bug#8664)
2074 * xselect.c (last_event_timestamp): Remove duplicate decl.
2075 (x_own_selection): Remove needless cast to unsigned long.
2077 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
2078 that always fit in int. Use a sentinel instead of a counter, to
2079 avoid a temp and to allay GCC's concerns about possible int overflow.
2080 * frame.h (struct frame): Use int for menu_bar_items_used
2081 instead of EMACS_INT, since it always fits in int.
2083 * menu.c (grow_menu_items): Check for int overflow.
2085 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
2087 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
2088 Before, the code was not consistent. These values cannot exceed
2089 2**31 - 1 so there's no need to make them unsigned.
2090 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
2091 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
2092 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
2094 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
2096 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
2097 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
2098 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
2099 presumably because the widths might not match.
2101 * window.c (size_window): Avoid needless test at loop start.
2103 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
2105 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
2107 2011-05-12 Drew Adams <drew.adams@oracle.com>
2109 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
2111 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2113 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
2114 `width' to `bar_area_x' and `bar_area_width', respectively.
2115 (x_scroll_run): Take account of fringe background extension.
2117 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
2118 Rename local vars `left' and `width' to `bar_area_x' and
2119 `bar_area_width', respectively.
2120 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
2121 background extension.
2123 2011-05-10 Jim Meyering <meyering@redhat.com>
2125 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
2127 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
2129 * image.c (Finit_image_library): Return t for built-in image types,
2130 like pbm and xbm. (Bug#8640)
2132 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
2134 * w32menu.c (set_frame_menubar): Fix submenu allocation.
2136 2011-05-07 Eli Zaretskii <eliz@gnu.org>
2138 * w32console.c (Fset_screen_color): Doc fix.
2139 (Fget_screen_color): New function.
2140 (syms_of_ntterm): Defsubr it.
2142 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
2143 unlink the temporary file if Fcall_process didn't create it in the
2145 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
2146 child process will be redirected to a file specified with `:file'.
2147 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
2148 cue to call_process_cleanup not to close that handle.
2150 2011-05-07 Ben Key <bkey76@gmail.com>
2152 * makefile.w32-in: The bootstrap-temacs rule now makes use of
2153 one of two shell specific rules, either bootstrap-temacs-CMD or
2154 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
2155 to the previous implementation of the bootstrap-temacs rule.
2156 The bootstrap-temacs-CMD rule is similar to the previous
2157 implementation of the bootstrap-temacs rule except that it
2158 makes use of the ESC_CFLAGS variable instead of the CFLAGS
2161 These changes, along with some changes to nt/configure.bat,
2162 nt/gmake.defs, and nt/nmake.defs, are required to extend my
2163 earlier fix to add support for --cflags and --ldflags options
2164 that include quotes so that it works whether make uses cmd or
2167 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
2169 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
2170 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
2172 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
2173 a string. Handle both cases.
2174 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
2175 (Fdbus_register_method): Use Qinvalid_function.
2177 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
2179 * makefile.w32-in: Update dependencies.
2180 (LISP_H): Add inttypes.h and stdin.h.
2181 (PROCESS_H): Add unistd.h.
2183 2011-05-06 Eli Zaretskii <eliz@gnu.org>
2185 * lread.c: Include limits.h (fixes the MS-Windows build broken by
2186 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
2188 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
2190 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
2192 * term.c (vfatal): Remove stray call to va_end.
2193 It's not needed and the C Standard doesn't allow it here anyway.
2195 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
2196 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
2198 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
2201 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
2203 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
2205 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
2207 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
2209 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
2211 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
2212 * charset.c (Fdefine_charset_internal): Don't initialize
2213 charset.code_space[15]. The value was garbage, on hosts with
2214 32-bit int (Bug#8600).
2216 * lread.c (read_integer): Be more consistent with string-to-number.
2217 Use string_to_number to do the actual conversion; this avoids
2218 rounding errors and fixes some other screwups. Without this fix,
2219 for example, #x1fffffffffffffff was misread as -2305843009213693952.
2220 (digit_to_number): Move earlier, for benefit of read_integer.
2221 Return -1 if the digit is out of range for the base, -2 if it is
2222 not a digit in any supported base. (Bug#8602)
2224 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
2226 * dispnew.c (scrolling_window): Return 1 if we scrolled,
2227 to match comment at start of function. This also removes a
2228 GCC warning about overflow in a 32+64-bit port.
2230 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
2232 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
2233 Reported by Stefan Monnier in
2234 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
2235 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
2236 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
2238 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
2239 (EMACS_UINTPTR): Likewise, with uintptr_t.
2241 * lisp.h: Prefer 64-bit EMACS_INT if available.
2242 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
2243 on 32-bit hosts that have 64-bit int, so that they can access
2245 However, temporarily disable this change unless the temporary
2246 symbol WIDE_EMACS_INT is defined.
2248 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
2250 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
2251 This removes an assumption that EMACS_INT and long are the same
2252 width as pointers. The assumption is true for Emacs porting targets
2253 now, but we want to make other targets possible.
2254 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
2255 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
2256 In the rest of the code, change types of integers that hold casted
2257 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
2258 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
2259 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
2260 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
2261 No need to cast type when ORing.
2262 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
2263 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
2264 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
2265 assume EMACS_INT is the same width as char *.
2266 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
2267 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
2268 Remove no-longer-needed casts.
2269 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
2270 (xg_tool_bar_help_callback, xg_make_tool_item):
2271 Use EMACS_INTPTR to hold an integer
2272 that will be cast to void *; this can avoid a GCC warning
2273 if EMACS_INT is not the same width as void *.
2274 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
2275 * xdisp.c (display_echo_area_1, resize_mini_window_1):
2276 (current_message_1, set_message_1):
2277 Use a local to convert to proper width without a cast.
2278 * xmenu.c (dialog_selection_callback): Likewise.
2280 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
2281 Also, don't assume VALBITS / RAND_BITS is less than 5,
2282 and don't rely on undefined behavior when shifting a 1 left into
2284 * lisp.h (get_random): Change signature to match.
2286 * lread.c (hash_string): Use size_t, not int, for hash computation.
2287 Normally we prefer signed values; but hashing is special, because
2288 it's better to use unsigned division on hash table sizes so that
2289 the remainder is nonnegative. Also, size_t is the natural width
2290 for hashing into memory. The previous code used 'int', which doesn't
2291 retain enough info to hash well into very large tables.
2292 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
2294 * dbusbind.c: Don't possibly lose pointer info when converting.
2295 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
2296 Use XPNTR rather than XHASH, so that the high-order bits of
2297 the pointer aren't lost when converting through void *.
2299 * eval.c (Fautoload): Don't double-shift a pointer.
2301 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
2303 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
2305 * gnutls.c (DEF_GNUTLS_FN):
2306 * image.c (DEF_IMGLIB_FN): Make function pointers static.
2308 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
2310 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
2313 2011-05-05 Eli Zaretskii <eliz@gnu.org>
2315 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
2316 New version that can reserve upto 2GB of heap space.
2318 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
2320 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
2322 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
2324 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
2325 `gnutls_certificate_set_x509_key_file'.
2327 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
2329 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
2330 Update dependencies.
2332 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
2334 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):

2433 (Fcall_process_region): Ditto.
2435 2011-04-30 Eli Zaretskii <eliz@gnu.org>
2437 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
2438 rather than `XVECTOR (FOO)->size'.
2440 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
2441 inttypes.h, as a gnulib replacement is used if it not available in

2451 will grow beyond MOST_POSITIVE_FIXNUM.
2452 (decode_coding_emacs_mule): Abort if there isn't enough place in
2453 charbuf for the composition carryover bytes. Reserve an extra
2454 space for up to 2 characters produced in a loop.
2455 (decode_coding_iso_2022): Abort if there isn't enough place in
2456 charbuf for the composition carryover bytes.
2458 2011-04-21 Eli Zaretskii <eliz@gnu.org>
2460 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
2461 aborting when %lld or %lll format is passed.
2462 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
2463 %llo or %llx format is passed. (Bug#8545)
2465 * window.c (window_scroll_line_based): Use a marker instead of
2466 simple variables to record original value of point. (Bug#7952)
2468 * doprnt.c (doprnt): Fix the case where a multibyte sequence
2469 produced by %s or %c overflows available buffer space. (Bug#8545)
2471 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
2473 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
2474 (SIZE_MAX): Move defn after all includes, as they might #define it.
2476 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
2478 * w32.c (init_environment): Warn about defaulting HOME to C:\.
2480 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
2482 * keyboard.c (Qdelayed_warnings_hook): Define.
2483 (command_loop_1): Run `delayed-warnings-hook'
2484 if Vdelayed_warnings_list is non-nil.
2485 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
2486 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
2488 2011-04-28 Eli Zaretskii <eliz@gnu.org>
2490 * doprnt.c (doprnt): Don't return value smaller than the buffer
2491 size if the message was truncated. (Bug#8545).
2493 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
2495 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
2496 (Fx_window_property): #if-0 the whole functions, not just the bodies.
2498 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
2500 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
2502 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
2504 * makefile.w32-in: Update dependencies.
2506 2011-04-27 Eli Zaretskii <eliz@gnu.org>
2508 Improve `doprnt' and its usage. (Bug#8545)
2509 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
2510 `format_end'. Remove support for %l as a conversion specifier.
2511 Don't use xrealloc. Improve diagnostics when the %l size modifier
2512 is used. Update the commentary.
2514 * eval.c (verror): Simplify calculation of size_t.
2516 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
2519 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
2521 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
2524 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
2526 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
2527 This makes this file independent of the recent pseudovector change.
2529 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
2531 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
2533 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
2534 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
2535 Remove unused local.
2536 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
2538 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
2539 GCC 4.6.0 optimizes based on type-based alias analysis.
2540 For example, if b is of type struct buffer * and v of type struct
2541 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
2542 != &v->size, and therefore "v->size = 1; b->size = 2; return
2543 v->size;" must therefore return 1. This assumption is incorrect
2544 for Emacs, since it type-puns struct Lisp_Vector * with many other
2545 types. To fix this problem, this patch adds a new type struct
2546 vectorlike_header that documents the constraints on layout of vectors
2547 and pseudovectors, and helps optimizing compilers not get fooled
2548 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
2549 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
2550 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
2552 (XSETPVECTYPE): Rewrite in terms of new macro.
2553 (XSETPVECTYPESIZE): New macro, specifying both type and size.
2554 This is a bit clearer, and further avoids the possibility of
2555 undesirable aliasing.
2556 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
2557 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
2558 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
2559 since Lisp_Subr is a special case (no "next" field).
2560 (ASIZE): Now uses header.size rather than size.
2561 All previous uses of XVECTOR (foo)->size replaced to use this macro,
2562 to avoid the hassle of writing XVECTOR (foo)->header.size.
2563 (struct vectorlike_header): New type.
2564 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
2565 object, to help avoid aliasing.
2566 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
2567 (SUBRP): Likewise, since Lisp_Subr is a special case.
2568 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
2569 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
2570 (struct Lisp_Hash_Table): Combine first two members into a single
2571 struct vectorlike_header member. All uses of "size" and "next" members
2572 changed to be "header.size" and "header.next".
2573 * buffer.h (struct buffer): Likewise.
2574 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
2575 * frame.h (struct frame): Likewise.
2576 * process.h (struct Lisp_Process): Likewise.
2577 * termhooks.h (struct terminal): Likewise.
2578 * window.c (struct save_window_data, struct saved_window): Likewise.
2579 * window.h (struct window): Likewise.
2580 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
2581 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
2582 * buffer.c (init_buffer_once): Likewise.
2583 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
2585 * process.c (Fformat_network_address): Use local var for size,
2588 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
2590 Make the Lisp reader and string-to-float more consistent (Bug#8525)
2591 * data.c (atof): Remove decl; no longer used or needed.
2592 (digit_to_number): Move to lread.c.
2593 (Fstring_to_number): Use new string_to_number function, to be
2594 consistent with how the Lisp reader treats infinities and NaNs.
2595 Do not assume that floating-point numbers represent EMACS_INT
2596 without losing information; this is not true on most 64-bit hosts.
2597 Avoid double-rounding errors, by insisting on integers when
2598 parsing non-base-10 numbers, as the documentation specifies.
2599 * lisp.h (string_to_number): New decl, replacing ...
2600 (isfloat_string): Remove.
2601 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
2602 (read1): Do not accept +. and -. as integers; this
2603 appears to have been a coding error. Similarly, do not accept
2604 strings like +-1e0 as floating point numbers. Do not report
2605 overflow for integer overflows unless the base is not 10 which
2606 means we have no simple and reliable way to continue.
2607 Break out the floating-point parsing into a new
2608 function string_to_number, so that Fstring_to_number parses
2609 floating point numbers consistently with the Lisp reader.
2610 (digit_to_number): Move here from data.c. Make it static inline.
2611 (E_CHAR, EXP_INT): Remove, replacing with ...
2612 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
2613 (string_to_number): New function, replacing isfloat_string.
2614 This function checks for valid syntax and produces the resulting
2615 Lisp float number too. Rework it so that string-to-number
2616 no longer mishandles examples like "1.0e+". Use strtoumax,
2617 so that overflow for non-base-10 numbers is reported only when
2618 there's no portable and simple way to convert to floating point.
2620 * textprop.c (set_text_properties_1): Rewrite for clarity,
2621 and to avoid GCC warning about integer overflow.
2623 * intervals.h (struct interval): Use EMACS_INT for members
2624 where EMACS_UINT might cause problems. See
2625 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
2626 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
2627 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
2629 (offset_intervals): Tell GCC not to worry about length overflow
2630 when negating a negative length.
2632 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
2633 (overrun_check_free): Likewise.
2635 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
2636 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
2639 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
2640 (gnutls_make_error): Rename local to avoid shadowing.
2641 (gnutls_emacs_global_deinit): ifdef out; not used.
2642 (Fgnutls_boot): Use const for pointer to readonly storage.
2643 Comment out unused local. Fix pointer signedness problems.
2645 * lread.c (openp): Don't stuff size_t into an 'int'.
2646 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
2647 about possible signed overflow.
2649 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
2650 (GDK_KEY_g): Don't define if already defined.
2651 (xg_prepare_tooltip): Avoid pointer signedness problem.
2652 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
2654 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
2655 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
2657 * xfns.c (Fx_window_property): Simplify a bit,
2658 to make a bit faster and to avoid GCC 4.6.0 warning.
2659 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
2661 * fns.c (internal_equal): Don't assume size_t fits in int.
2663 * alloc.c (compact_small_strings): Tighten assertion a little.
2665 Replace pEd with more-general pI, and fix some printf arg casts.
2666 * lisp.h (pI): New macro, generalizing old pEd macro to other
2667 conversion specifiers. For example, use "...%"pI"d..." rather
2668 than "...%"pEd"...".
2669 (pEd): Remove. All uses replaced with similar uses of pI.
2670 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
2671 * alloc.c (check_pure_size): Don't overflow by converting size to int.
2672 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
2673 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
2674 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
2675 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
2676 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
2678 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
2679 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
2680 * print.c (safe_debug_print, print_object): Likewise.
2681 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
2683 Use pI instead of if-then-else-abort. Use %p to avoid casts,
2684 avoiding the 0 flag, which is not portable.
2685 * process.c (Fmake_network_process): Use pI to avoid cast.
2686 * region-cache.c (pp_cache): Likewise.
2687 * xdisp.c (decode_mode_spec): Likewise.
2688 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
2689 behavior on 64-bit hosts with printf arg.
2690 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
2691 (x_stop_queuing_selection_requests): Likewise.
2692 (x_get_window_property): Don't truncate byte count to an 'int'
2695 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
2696 here, since it parses constructs like leading '-' and spaces,
2697 which are not wanted; and it overflows with large numbers.
2698 Instead, simply match F[0-9]+, which is what is wanted anyway.
2700 * alloc.c: Remove unportable assumptions about struct layout.
2701 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
2702 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
2703 (allocate_vectorlike, make_pure_vector): Use the new macros,
2704 plus offsetof, to remove unportable assumptions about struct layout.
2705 These assumptions hold on all porting targets that I know of, but
2706 they are not guaranteed, they're easy to remove, and removing them
2707 makes further changes easier.
2709 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
2710 This doesn't fix a bug but makes the code clearer.
2711 (string_overrun_cookie): Now const. Use initializers that
2712 don't formally overflow signed char, to avoid warnings.
2713 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
2714 can cause Emacs to crash when string overrun checking is enabled.
2715 (allocate_buffer): Don't assume sizeof (struct buffer) is a
2716 multiple of sizeof (EMACS_INT); it need not be, if
2717 alignof(EMACS_INT) < sizeof (EMACS_INT).
2718 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
2720 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
2722 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
2724 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>

2727 supposed to be handshaking. (Bug#8556)
2728 Reported by Paul Eggert <eggert@cs.ucla.edu>.

2733 * eval.c (Qdebug): Restore global linkage.
2734 * keyboard.c (debug-on-event): New variable.
2735 (handle_user_signal): Break into debugger when debug-on-event
2736 matches the current signal symbol.
2738 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
2740 * alloc.c (check_sblock, check_string_bytes)
2741 (check_string_free_list): Convert to standard C.
2743 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
2745 * w32.c (emacs_gnutls_push): Fix typo.
2747 2011-04-25 Eli Zaretskii <eliz@gnu.org>
2749 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
2750 "cast to pointer from integer of different size".
2752 Improve doprnt and its use in verror. (Bug#8545)
2753 * doprnt.c (doprnt): Document the set of format control sequences
2754 supported by the function. Use SAFE_ALLOCA instead of always
2757 * eval.c (verror): Don't limit the buffer size at size_max-1, that
2758 is one byte too soon. Don't use xrealloc; instead xfree and
2761 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
2763 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
2766 * gnutls.c: Renamed global_initialized to
2767 gnutls_global_initialized. Added internals for the
2768 :verify-hostname-error, :verify-error, and :verify-flags
2769 parameters of `gnutls-boot' and documented those parameters in the
2770 docstring. Start callback support.
2771 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
2772 unless a fatal error occured. Call gnutls_alert_send_appropriate

3300 * fontset.h (face_suitable_for_char_p): Remove decl.
3301 * xfaces.c (face_at_string_position):
3302 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
3303 since 0 is always ASCII.
3305 * fns.c (weak_hash_tables): Now static.
3307 * fileio.c: Make symbols static if they're not exported.

3326 * editfns.c, lisp.h (get_operating_system_release): Remove.
3327 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
3328 worth the hassle of breaking this out.

3469 * xdisp.c (message_enable_multibyte): Now static.
3471 Declare Lisp_Object Q* variables to be 'static' if not exported.

3473 to see whether these variables are used from other modules.

3485 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
3487 * lisp.h (DEFINE_FUNC): Make sname 'static'.
3489 Make Emacs functions such as Fatom 'static' by default.
3490 This makes it easier for human readers (and static analyzers)
3491 to see whether these functions can be called from other modules.
3492 DEFUN now defines a static function. To make the function external
3493 so that it can be used in other C modules, use the new macro DEFUE.

3499 Remove decls, since these functions are now static.
3500 (Funintern, Fget_internal_run_time): New decls, since these functions
3501 were already external.

3554 when at ZV. (Bug#8487)
3556 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
3558 * charset.c (Fclear_charset_maps): Use xfree instead of free.

3561 * sound.c (sound_cleanup, alsa_close): Likewise.
3562 * termcap.c (tgetent): Likewise.

3569 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
3571 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
3572 since callers should never pass a negative size.
3573 Change the signature to match that of plain 'read' and 'write'; see
3574 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
3575 * lisp.h: Update prototypes of emacs_write and emacs_read.
3577 2011-04-11 Eli Zaretskii <eliz@gnu.org>
3579 * xdisp.c (redisplay_window): Don't try to determine the character
3580 position of the scroll margin if the window start point w->startp
3581 is outside the buffer's accessible region. (Bug#8468)
3583 2011-04-10 Eli Zaretskii <eliz@gnu.org>
3585 Fix write-region and its subroutines for buffers > 2GB.
3586 * fileio.c (a_write, e_write): Modify declaration of arguments and
3587 local variables to support buffers larger than 2GB.
3588 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
3590 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
3591 argument, local variables, and return value.
3593 * lisp.h: Update prototypes of emacs_write and emacs_read.
3595 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
3597 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
3599 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
3601 Fix more problems found by GCC 4.6.0's static checks.
3603 * xdisp.c (vmessage): Use a better test for character truncation.
3605 * charset.c (load_charset_map): <, not <=, for optimization,
3606 and to avoid potential problems with integer overflow.
3607 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
3608 * casetab.c (set_identity, shuffle): Likewise.
3609 * editfns.c (Fformat): Likewise.
3610 * syntax.c (skip_chars): Likewise.
3612 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
3613 This also lets GCC 4.6.0 generate slightly better loop code.
3615 * callint.c (Fcall_interactively): <, not <=, for optimization.
3616 (Fcall_interactively): Count the number of arguments produced,
3617 not the number of arguments given. This is simpler and lets GCC
3618 4.6.0 generate slightly better code.
3620 * ftfont.c: Distingish more carefully between FcChar8 and char.
3621 The previous code passed unsigned char * to a functions like
3622 strlen and xstrcasecmp that expect char *, which does not
3623 conform to the C standard.
3624 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
3625 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
3626 char * when the C standard requires it.
3628 * keyboard.c (read_char): Remove unused var.
3630 * eval.c: Port to Windows vsnprintf (Bug#8435).
3632 (SIZE_MAX): Define if the headers do not.
3633 (verror): Do not give up if vsnprintf returns a negative count.
3634 Instead, grow the buffer. This ports to Windows vsnprintf, which
3635 does not conform to C99. Problem reported by Eli Zaretskii.
3636 Also, simplify the allocation scheme, by avoiding the need for
3637 calling realloc, and removing the ALLOCATED variable.
3639 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
3641 Remove invocations of doprnt, as Emacs now uses vsnprintf.
3642 But keep the doprint source code for now, as we might revamp it
3643 and use it again (Bug#8435).
3644 * lisp.h (doprnt): Remove.
3645 * Makefile.in (base_obj): Remove doprnt.o.
3646 * deps.mk (doprnt.o): Remove.
3648 error: Print 32- and 64-bit integers portably (Bug#8435).
3649 Without this change, on typical 64-bit hosts error ("...%d...", N)
3650 was used to print both 32- and 64-bit integers N, which relied on
3652 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
3654 * lisp.h (error, verror): Mark as printf-like functions.
3655 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
3656 Report overflow in size calculations when allocating printf buffer.
3657 Do not truncate output string at its first null byte.
3658 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
3659 Truncate the output at a character boundary, since vsnprintf does not
3661 * charset.c (check_iso_charset_parameter): Convert internal
3662 character to string before calling 'error', since %c now has the
3664 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
3665 overflow when computing char to be passed to 'error'. Do not
3666 pass Lisp_Object to 'error'; pass the integer instead.
3667 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
3668 formatted with plain %d.
3670 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
3672 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
3674 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
3676 * xterm.c (x_catch_errors): Remove duplicate declaration.
3678 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
3680 * xdisp.c, lisp.h (message_nolog): Remove; unused.
3682 2011-04-10 Jim Meyering <meyering@redhat.com>
3684 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
3685 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
3686 return ssize_t not "int", and use size_t as the buffer length.
3687 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
3688 * gnutls.h: Update declarations.
3689 * process.c (read_process_output): Use ssize_t, to match.
3690 (send_process): Likewise.
3692 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
3694 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
3696 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
3698 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
3699 Use unsigned char, to match FcChar8 type definition.

3711 (scan_buffer, find_next_newline_no_quit)
3712 (find_before_next_newline, search_command, Freplace_match)
3713 (Fmatch_data): Make some `int' variables be EMACS_INT.

3733 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
3735 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
3736 (encode_invocation_designation): Last argument P_NCHARS is now
3738 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.

3762 instead of using internal_with_output_to_temp_buffer.
3763 (Qhelp_form_show): New var.
3764 (syms_of_keyboard): Use DEFSYM macro.
3766 * print.c (internal_with_output_to_temp_buffer): Function deleted.

3781 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
3783 Fix more problems found by GCC 4.6.0's static checks.
3785 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.

3802 * eval.c (Fsignal): Remove excess argument to 'fatal'.
3804 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
3805 This avoids several warnings with gcc -Wstrict-overflow.
3806 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
3807 directly, rather than having caller test rule sign. This avoids
3808 some unnecessary tests.
3809 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
3810 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
3811 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
3813 * xfont.c (xfont_text_extents): Remove var that was set but not used.
3814 (xfont_open): Avoid unnecessary tests.
3816 * composite.c (composition_gstring_put_cache): Use unsigned integer.

3822 breaking out part of COMPOSITION_DECODE_RULE.
3823 (COMPOSITION_DECODE_RULE): Use it.
3824 * composite.c (get_composition_id): Remove unused local vars,
3825 by using the new macro.
3827 * textprop.c (set_text_properties_1): Change while to do-while,
3828 since the condition is always true at first.
3830 * intervals.c (graft_intervals_into_buffer): Mark var as used.
3831 (interval_deletion_adjustment): Return unsigned value.
3834 * process.c (list_processes_1, create_pty, read_process_output):

3861 * eval.c (funcall_lambda): Rename local to avoid shadowing.
3863 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
3864 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
3865 can always succeed if overflow has undefined behavior.
3867 * search.c (boyer_moore, wordify): Remove vars set but not used.
3868 (wordify): Omit three unnecessary tests.
3870 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
3871 All callers changed. This avoids the need for an unused var.
3873 * casefiddle.c (casify_region): Remove var that is set but not used.
3875 * dired.c (file_name_completion): Remove var that is set but not used.
3877 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
3879 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
3880 (Finsert_file_contents): Remove unnecessary code checking fd.
3882 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
3883 Check for integer overflow on size calculations.
3885 * buffer.c (Fprevious_overlay_change): Remove var that is set
3888 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
3889 Remove vars that are set but not used.
3890 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
3891 (timer_check_2): Mark vars as initialized.
3893 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
3895 * image.c (lookup_image): Remove var that is set but not used.
3896 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
3898 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
3899 that are set but not used.
3901 * xfns.c (make_invisible_cursor): Don't return garbage
3902 if XCreateBitmapFromData fails (Bug#8410).
3904 * xselect.c (x_get_local_selection, x_handle_property_notify):
3905 Remove vars that are set but not used.
3907 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
3908 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
3910 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
3911 Remove var that is set but not used.
3912 (scroll_bar_windows_size): Now size_t, not int.
3913 (x_send_scroll_bar_event): Use size_t, not int, for sizes.

3917 (map_tty_color) [!defined MSDOS]: Likewise.
3919 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
3921 * coding.c: Remove vars that are set but not used.
3922 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
3923 All callers changed.
3924 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
3925 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
3926 (decode_coding_charset): Remove vars that are set but not used.
3928 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
3929 that is set but not used.
3931 * print.c (print_object): Remove var that is set but not used.
3933 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
3934 The gnulib version avoids calling malloc in the usual case,
3935 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
3936 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
3937 * filelock.c (current_lock_owner): Likewise.
3938 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
3939 * sysdep.c: Include allocator.h, careadlinkat.h.
3940 (emacs_no_realloc_allocator): New static constant.
3941 (emacs_readlink): New function.
3942 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on

3945 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
3947 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
3948 first non-nil return value).
3950 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
3952 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
3953 if not defined (Bug#8403).
3955 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
3957 * xdisp.c (display_count_lines): Remove parameter `start',
3958 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
3959 (get_char_face_and_encoding): Remove parameter `multibyte_p',
3960 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

3962 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
3963 and thereabouts. All callers changed.
3964 (get_per_char_metric): Remove parameter `f', unused since
3965 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
3967 2011-04-02 Jim Meyering <meyering@redhat.com>
3969 do not dereference NULL upon failed strdup
3970 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
3971 (ns_get_family): Likewise.
3973 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
3975 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
3977 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
3979 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
3982 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
3984 Add lexical binding.
3986 * window.c (Ftemp_output_buffer_show): New fun.
3987 (Fsave_window_excursion):
3988 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
3990 * lread.c (lisp_file_lexically_bound_p): New function.
3991 (Fload): Bind Qlexical_binding.
3992 (readevalloop): Remove `evalfun' arg.
3993 Bind Qinternal_interpreter_environment.
3994 (Feval_buffer): Bind Qlexical_binding.
3995 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
3997 (syms_of_lread): Declare `lexical-binding'.
3999 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
4001 * keyboard.c (eval_dyn): New fun.
4002 (menu_item_eval_property): Use it.
4004 * image.c (parse_image_spec): Use Ffunctionp.
4006 * fns.c (concat, mapcar1): Accept byte-code-functions.
4008 * eval.c (Fsetq): Handle lexical vars.
4009 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
4010 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
4011 (FletX, Flet): Obey lexical binding.
4012 (Fcommandp): Handle closures.
4013 (Feval): New `lexical' arg.
4014 (eval_sub): New function extracted from Feval. Use it almost
4015 everywhere where Feval was used. Look up vars in lexical env.
4017 (Ffunctionp): Move from subr.el.
4018 (Ffuncall): Handle closures.
4019 (apply_lambda): Remove `eval_flags'.
4020 (funcall_lambda): Handle closures and new byte-code-functions.
4021 (Fspecial_variable_p): New function.
4022 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
4023 but without exporting it to Lisp.
4025 * doc.c (Fdocumentation, store_function_docstring):
4026 * data.c (Finteractive_form): Handle closures.
4028 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
4031 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
4033 (exec_byte_code): New function extracted from Fbyte_code to handle new
4034 calling convention for byte-code-functions. Add new byte-codes.
4036 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
4038 * alloc.c (Fmake_symbol): Init new `declared_special' field.
4040 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
4042 * xdisp.c (redisplay_internal): Fix prototype.
4044 2011-03-31 Eli Zaretskii <eliz@gnu.org>
4046 * xdisp.c (SCROLL_LIMIT): New macro.
4047 (try_scrolling): Use it when setting scroll_limit.
4048 Limit scrolling to 100 screen lines.
4049 (redisplay_window): Even when falling back on "recentering",
4050 position point in the window according to scroll-conservatively,
4051 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
4053 (try_scrolling): When point is above the window, allow searching
4054 as far as scroll_max, or one screenful, to compute vertical
4055 distance from PT to the scroll margin position. This prevents
4056 try_scrolling from unnecessarily failing when
4057 scroll-conservatively is set to a value slightly larger than the
4058 window height. Clean up the case of PT below the margin at bottom
4059 of window: scroll_max can no longer be INT_MAX. When aggressive
4060 scrolling is in use, don't let point enter the opposite scroll
4061 margin as result of the scroll.
4062 (syms_of_xdisp) <scroll-conservatively>: Document the
4063 threshold of 100 lines for never-recentering scrolling.
4065 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
4067 * dispextern.h (move_it_by_lines):
4068 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
4069 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
4070 (message_log_check_duplicate): Remove parameters `prev_bol' and
4071 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
4072 (redisplay_internal): Remove parameter `preserve_echo_area',
4073 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
4075 * indent.c (Fvertical_motion):
4076 * window.c (window_scroll_pixel_based, Frecenter):
4077 Don't pass `need_y_p' to `move_it_by_lines'.
4079 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
4081 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
4082 steal a few bits to be more compact.
4083 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
4084 Remove unneeded casts.
4086 * bytecode.c (Fbyte_code): CAR and CDR can GC.
4088 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
4090 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
4091 binding" message (bug#7967).
4093 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
4095 Fix more problems found by GCC 4.6.0's static checks.
4097 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
4098 Remove unused local var.
4100 * editfns.c (Fmessage_box): Remove unused local var.
4102 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
4103 (note_mode_line_or_margin_highlight, note_mouse_highlight):
4104 Omit unused local vars.
4105 * window.c (shrink_windows): Omit unused local var.
4106 * menu.c (digest_single_submenu): Omit unused local var.
4107 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
4108 Omit unused local var.
4110 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
4111 Don't assume string length fits in int.
4112 (keyremap_step, read_key_sequence): Use size_t for sizes.
4113 (read_key_sequence): Don't check last_real_key_start redundantly.
4115 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
4116 instead of alloca (Bug#8344).
4118 * eval.c (Fbacktrace): Don't assume nargs fits in int.
4119 (Fbacktrace_frame): Don't assume nframes fits in int.
4121 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
4123 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
4126 * term.c (produce_glyphless_glyph): Remove unnecessary test.
4128 * cm.c (calccost): Turn while-do into do-while, for clarity.
4130 * keyboard.c (syms_of_keyboard): Use the same style as later
4131 in this function when indexing through an array. This also
4132 works around GCC bug 48267.
4134 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
4136 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
4138 * chartab.c (sub_char_table_ref_and_range): Redo for slight
4139 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
4141 * keyboard.c, keyboard.h (num_input_events): Now size_t.
4142 This avoids undefined behavior on integer overflow, and is a bit
4143 more convenient anyway since it is compared to a size_t variable.
4145 Variadic C functions now count arguments with size_t, not int.
4146 This avoids an unnecessary limitation on 64-bit machines, which
4147 caused (substring ...) to crash on large vectors (Bug#8344).
4148 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
4149 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

4155 (internal_condition_case_n, run_hook_with_args, apply_lambda)
4156 (funcall_lambda, mark_backtrace): Likewise.
4157 * fns.c (concat): Likewise.
4158 * frame.c (x_set_frame_parameters): Likewise.
4159 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
4160 0 if not found, not -1. All callers changed.
4162 * alloc.c (garbage_collect): Don't assume stack size fits in int.
4163 (stack_copy_size): Now size_t, not int.
4164 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
4166 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
4168 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
4169 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
4170 All callers changed.
4172 * lisp.h (multibyte_char_to_unibyte):
4173 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
4174 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

4370 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
4372 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
4373 unconditionnaly since it does the check itself.
4375 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
4377 Fix more problems found by GCC 4.5.2's static checks.
4379 * coding.c (encode_coding_raw_text): Avoid unnecessary test
4380 the first time through the loop, since we know p0 < p1 then.
4381 This also avoids a gcc -Wstrict-overflow warning.
4383 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
4384 leading to a memory leak, possible in functions like
4385 load_charset_map_from_file that can allocate an unbounded number
4386 of objects (Bug#8318).
4388 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
4389 that could (at least in theory) be that large.
4391 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
4392 This is less likely to overflow, and avoids undefined behavior if
4393 overflow does occur. All callers changed. Use strtoul to scan

4411 * process.c (Fmake_network_process): Use socklen_t, not int,
4412 where POSIX says socklen_t is required in portable programs.
4413 This fixes a porting bug on hosts like 64-bit HP-UX, where
4414 socklen_t is wider than int (Bug#8277).
4415 (Fmake_network_process, server_accept_connection):
4416 (wait_reading_process_output, read_process_output):

4431 Include tparam.h instead, since it declares them.
4432 * cm.h (PC): Remove extern decl; tparam.h now does this.
4433 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
4434 * terminfo.c: Include tparam.h, to check interfaces.
4435 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
4436 (tparam): Adjust signature to match interface in tparam.h;
4437 this removes some undefined behavior. Check that outstring and len
4438 are zero, which they always are with Emacs.
4439 * tparam.h (PC, BC, UP): New extern decls.
4441 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
4442 (xftfont_open): Rename locals to avoid shadowing.

4484 behavior (Bug#8278).
4486 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
4488 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
4490 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
4491 clobbering (Bug#8298).
4492 * sysdep.c (sys_subshell): Likewise.
4493 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
4495 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
4496 This should get cleaned up, so that child_setup has the
4497 same signature on all platforms.
4499 * callproc.c (call_process_cleanup): Now static.
4500 (relocate_fd): Rename locals to avoid shadowing.
4502 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
4504 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
4505 not to be necessary, and produces flickering.

4509 * config.in: Remove file.
4511 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

4562 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
4564 * deps.mk (unexalpha.o): Remove; unused.
4566 New file unexec.h, the (simple) interface for unexec (Bug#8267).

4653 Rename locals to avoid shadowing.
4654 (mark_stack): Move local variables into the #ifdef region where
4656 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
4657 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
4659 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
4660 (GC_STRING_CHARS): Remove; not used.
4661 (Fmemory_limit): Cast sbrk's returned value to char *.
4663 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
4664 avoids undefined behavior in theory.
4666 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
4668 Use functions, not macros, for up- and down-casing (Bug#8254).
4669 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
4670 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
4671 to use the following functions instead of these macros.
4672 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
4673 EMACS_INT, since callers assume the returned value fits in int.
4674 (upcase1): Likewise, for UPCASE_TABLE.
4675 (uppercasep, lowercasep, upcase): New static inline functions.
4676 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
4677 the race-condition problem in the old DOWNCASE.
4679 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):

4681 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
4682 (regex_compile, re_search_2, re_match_2_internal):
4683 Remove unused local vars.
4684 (FREE_VAR): Rewrite so as not to use empty "else",
4685 which gcc can warn about.
4686 (regex_compile, re_match_2_internal): Mark locals as initialized.
4687 (RETALLOC_IF): Define only if needed.
4688 (WORDCHAR_P): Likewise. This one is never needed, but is used
4689 only in a comment talking about a compiler bug, so put inside
4690 the #if 0 of that comment.
4691 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
4692 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
4695 * search.c (boyer_moore): Rename locals to avoid shadowing.

4713 * casefiddle.c (casify_object, casify_region): Now static.
4714 (casify_region): Mark local as initialized.

4718 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
4719 New macros, so that the caller can use some names other than
4720 gcpro1, gcpro2, etc.
4721 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
4723 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
4724 argument, for consistency with GCPRO2_VAR, etc: it is now the
4725 prefix of the variable, not the variable itself. All uses
4727 * dired.c (directory_files_internal, file_name_completion):
4728 Rename locals to avoid shadowing.
4730 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
4731 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
4732 dired.c's scmp function, had undefined behavior.
4733 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
4734 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
4735 * buffer.h: ... to here, because these macros use current_buffer,
4736 and the new implementation with inline functions needs to have
4737 current_buffer in scope now, rather than later when the macros
4739 (downcase, upcase1): New static inline functions.
4740 (DOWNCASE, UPCASE1): Reimplement using these functions.
4741 This avoids undefined behavior in expressions like
4742 DOWNCASE (x) == DOWNCASE (y), which previously suffered
4743 from race conditions in accessing the global variables
4744 case_temp1 and case_temp2.
4745 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
4746 * lisp.h (case_temp1, case_temp2): Remove their decls.
4747 * character.h (ASCII_CHAR_P): Move from here ...
4748 * lisp.h: ... to here, so that the inline functions mentioned
4751 * dired.c (directory_files_internal_unwind): Now static.
4753 * fileio.c (file_name_as_directory, directory_file_name):
4754 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
4756 (file_name_as_directory): Use const pointers when appropriate.
4757 (Fexpand_file_name): Likewise. In particular, newdir might
4758 point at constant storage, so make it a const pointer.
4759 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
4760 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
4762 (Fset_file_times, Finsert_file_contents, auto_save_error):
4763 Rename locals to avoid shadowing.

4769 * marker.c (bytepos_to_charpos): Remove; unused.
4771 * lisp.h (verify_bytepos, count_markers): New decls,
4772 so that gcc does not warn that these functions aren't declared.
4774 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
4775 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
4776 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
4777 (copy_text): Remove unused local var.
4779 * filelock.c (within_one_second): Now static.
4780 (lock_file_1): Rename local to avoid shadowing.
4782 * buffer.c (fix_overlays_before): Mark locals as initialized.
4783 (fix_start_end_in_overlays): Likewise. This function should be
4784 simplified by using pointers-to-pointers, but that's a different
4786 (switch_to_buffer_1): Now static.
4787 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
4788 (report_overlay_modification): Rename locals to avoid shadowing.
4790 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
4791 Fix pointer signedness issue.
4792 (sys_subshell): Mark local as volatile if checking for lint,
4793 to suppress a gcc -Wclobbered warning that does not seem to be right.
4794 (MAXPATHLEN): Define only if needed.
4796 * process.c (serial_open, serial_configure): Move decls from here ...
4797 * systty.h: ... to here, so that they can be checked.
4799 * fns.c (get_random, seed_random): Move extern decls from here ...
4800 * lisp.h: ... to here, so that they can be checked.
4802 * sysdep.c (reset_io): Now static.
4803 (wait_for_termination_signal): Remove; unused.
4805 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
4806 (copy_keymap_item, append_key, push_text_char_description):
4808 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
4809 (DENSE_TABLE_SIZE): Remove; unused.

4811 (describe_map_tree):
4812 Rename locals to avoid shadowing.
4814 * keyboard.c: Declare functions static if they are not used elsewhere.
4815 (echo_char, echo_dash, cmd_error, top_level_2):
4816 (poll_for_input, handle_async_input): Now static.
4817 (read_char, kbd_buffer_get_event, make_lispy_position):
