146 --enable-checking=xmallocoverrun). xfree is now used to

498 * buffer.c (buffer_count): Remove unused var.
500 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
501 so that it's not optimized away.
502 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
503 * dispextern.h (bidi_dump_cached_states): Remove, since it's
504 exported only to the debugger.
506 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
507 * atimer.h (run_all_atimers): Removed; not exported.
509 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
510 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
511 was inaccessible from Lisp.

513 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
515 alloc.c: Import and export fewer symbols, and remove unused items.
516 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
518 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
519 it's not optimized away by whole-program optimization.
520 (message_enable_multibyte, free_misc): Remove.
521 (catchlist, handlerlist, mark_backtrace):
522 Declare only if BYTE_MARK_STACK.
523 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
524 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
525 (message_enable_multibyte): Remove decl.
526 (free_misc, interval_free_list, float_block, float_block_index):
527 (n_float_blocks, float_free_list, cons_block, cons_block_index):
528 (cons_free_list, last_marked_index):
530 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
531 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
532 (mark_backtrace): Define only if BYTE_MARK_STACK.
533 * xdisp.c (message_enable_multibyte): Now static.
535 Declare Lisp_Object Q* variables to be 'static' if not exproted.
536 This makes it easier for human readers (and static analyzers)
537 to see whether these variables are used from other modules.
538 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
539 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

543 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
544 * xmenu.c, xselect.c:
545 Declare Q* vars static if they are not used in other modules.
546 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
547 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
548 Remove decls of unexported vars.
549 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
551 * lisp.h (DEFINE_FUNC): Make sname 'static'.
553 Make Emacs functions such as Fatom 'static' by default.
554 This makes it easier for human readers (and static analyzers)
555 to see whether these functions can be called from other modules.
556 DEFUN now defines a static function. To make the function external
557 so that it can be used in other C modules, use the new macro DEFUE.
558 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
559 (Finit_image_library):
560 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
561 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
562 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
563 Remove decls, since these functions are now static.
564 (Funintern, Fget_internal_run_time): New decls, since these functions
565 were already external.
567 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
568 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

574 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
575 Mark functions with DEFUE instead of DEFUN,
576 if they are used in other modules.

615 2011-04-13 Eli Zaretskii <eliz@gnu.org>
617 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
618 when at ZV. (Bug#8487)
620 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
622 * charset.c (Fclear_charset_maps): Use xfree instead of free.
624 * keyboard.c (parse_tool_bar_item): Likewise.
625 * sound.c (sound_cleanup, alsa_close): Likewise.
626 * termcap.c (tgetent): Likewise.
627 * xfns.c (x_default_font_parameter): Likewise.
628 * xsettings.c (read_and_apply_settings): Likewise.
630 * alloc.c (overrun_check_malloc, overrun_check_realloc)
631 (overrun_check_free): Protoize.
633 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
635 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
636 since callers should never pass a negative size.
637 Change the signature to match that of plain 'read' and 'write'; see
638 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
639 * lisp.h: Update prototypes of emacs_write and emacs_read.
641 2011-04-11 Eli Zaretskii <eliz@gnu.org>
643 * xdisp.c (redisplay_window): Don't try to determine the character
644 position of the scroll margin if the window start point w->startp
645 is outside the buffer's accessible region. (Bug#8468)
647 2011-04-10 Eli Zaretskii <eliz@gnu.org>
649 Fix write-region and its subroutines for buffers > 2GB.
650 * fileio.c (a_write, e_write): Modify declaration of arguments and
651 local variables to support buffers larger than 2GB.
652 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
654 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
655 argument, local variables, and return value.
657 * lisp.h: Update prototypes of emacs_write and emacs_read.
659 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
661 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
663 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
665 Fix more problems found by GCC 4.6.0's static checks.
667 * xdisp.c (vmessage): Use a better test for character truncation.
669 * charset.c (load_charset_map): <, not <=, for optimization,
670 and to avoid potential problems with integer overflow.
671 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
672 * casetab.c (set_identity, shuffle): Likewise.
673 * editfns.c (Fformat): Likewise.
674 * syntax.c (skip_chars): Likewise.
676 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
677 This also lets GCC 4.6.0 generate slightly better loop code.
679 * callint.c (Fcall_interactively): <, not <=, for optimization.
680 (Fcall_interactively): Count the number of arguments produced,
681 not the number of arguments given. This is simpler and lets GCC
682 4.6.0 generate slightly better code.
684 * ftfont.c: Distingish more carefully between FcChar8 and char.
685 The previous code passed unsigned char * to a functions like
686 strlen and xstrcasecmp that expect char *, which does not
687 conform to the C standard.
688 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
689 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
690 char * when the C standard requires it.
692 * keyboard.c (read_char): Remove unused var.
694 * eval.c: Port to Windows vsnprintf (Bug#8435).
696 (SIZE_MAX): Define if the headers do not.
697 (verror): Do not give up if vsnprintf returns a negative count.
698 Instead, grow the buffer. This ports to Windows vsnprintf, which
699 does not conform to C99. Problem reported by Eli Zaretskii.
700 Also, simplify the allocation scheme, by avoiding the need for
701 calling realloc, and removing the ALLOCATED variable.
703 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
705 Remove invocations of doprnt, as Emacs now uses vsnprintf.
706 But keep the doprint source code for now, as we might revamp it
707 and use it again (Bug#8435).
708 * lisp.h (doprnt): Remove.
709 * Makefile.in (base_obj): Remove doprnt.o.
710 * deps.mk (doprnt.o): Remove.
712 error: Print 32- and 64-bit integers portably (Bug#8435).
713 Without this change, on typical 64-bit hosts error ("...%d...", N)
714 was used to print both 32- and 64-bit integers N, which relied on
716 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
718 * lisp.h (error, verror): Mark as printf-like functions.
719 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
720 Report overflow in size calculations when allocating printf buffer.
721 Do not truncate output string at its first null byte.
722 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
723 Truncate the output at a character boundary, since vsnprintf does not
725 * charset.c (check_iso_charset_parameter): Convert internal
726 character to string before calling 'error', since %c now has the
728 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
729 overflow when computing char to be passed to 'error'. Do not
730 pass Lisp_Object to 'error'; pass the integer instead.
731 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
732 formatted with plain %d.
734 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
736 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
738 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
740 * xterm.c (x_catch_errors): Remove duplicate declaration.
742 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
744 * xdisp.c, lisp.h (message_nolog): Remove; unused.
746 2011-04-10 Jim Meyering <meyering@redhat.com>
748 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
749 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
750 return ssize_t not "int", and use size_t as the buffer length.
751 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
752 * gnutls.h: Update declarations.
753 * process.c (read_process_output): Use ssize_t, to match.
754 (send_process): Likewise.
756 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
758 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
760 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
762 * ftfont.c (get_adstyle_property, ftfont_pattern_entity): Use
763 unsigned char, to match FcChar8 type definition.
765 * xterm.c (handle_one_xevent):
766 * xmenu.c (create_and_show_popup_menu):
767 * xselect.c (x_decline_selection_request)
768 (x_reply_selection_request): Avoid type-punned deref of X events.
770 2011-04-09 Eli Zaretskii <eliz@gnu.org>
772 Fix some uses of `int' instead of EMACS_INT.
773 * search.c (string_match_1, fast_string_match)
774 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
775 (scan_buffer, find_next_newline_no_quit)
776 (find_before_next_newline, search_command, Freplace_match)
777 (Fmatch_data): Make some `int' variables be EMACS_INT.
779 * xdisp.c (display_count_lines): 3rd argument and return value now
780 EMACS_INT. All callers changed.
781 (pint2hrstr): Last argument is now EMACS_INT.
783 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
784 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
785 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
786 (decode_coding_utf_16, decode_coding_emacs_mule)
787 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
788 (decode_coding_ccl, decode_coding_charset)
789 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.

791 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
792 <char_offset, last_offset>: Declare EMACS_INT.
793 (encode_coding_utf_8, encode_coding_utf_16)
794 (encode_coding_emacs_mule, encode_invocation_designation)
795 (encode_designation_at_bol, encode_coding_iso_2022)
796 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
797 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
799 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
800 (encode_invocation_designation): Last argument P_NCHARS is now
802 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
803 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
805 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
808 * ccl.c (Fccl_execute_on_string): Declare some variables
811 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
813 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).

823 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
825 * keyboard.c (read_char): Call Lisp function help-form-show,
826 instead of using internal_with_output_to_temp_buffer.
827 (Qhelp_form_show): New var.
828 (syms_of_keyboard): Use DEFSYM macro.
830 * print.c (internal_with_output_to_temp_buffer): Function deleted.
832 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
834 2011-04-06 Chong Yidong <cyd@stupidchicken.com>

843 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
845 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
847 Fix more problems found by GCC 4.6.0's static checks.
849 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
851 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
853 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
855 * xdisp.c (vmessage): Mark as a printf-like function.

862 printf-like functions.
863 (tiff_load): Add casts to remove these marks before passing them
864 to system-supplied API.
866 * eval.c (Fsignal): Remove excess argument to 'fatal'.
868 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
869 This avoids several warnings with gcc -Wstrict-overflow.
870 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
871 directly, rather than having caller test rule sign. This avoids
872 some unnecessary tests.
873 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
874 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
875 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
877 * xfont.c (xfont_text_extents): Remove var that was set but not used.
878 (xfont_open): Avoid unnecessary tests.
880 * composite.c (composition_gstring_put_cache): Use unsigned integer.
882 * composite.h, composite.c (composition_gstring_put_cache):
883 Use EMACS_INT, not int, for length.
885 * composite.h (COMPOSITION_DECODE_REFS): New macro,
886 breaking out part of COMPOSITION_DECODE_RULE.
887 (COMPOSITION_DECODE_RULE): Use it.
888 * composite.c (get_composition_id): Remove unused local vars,
889 by using the new macro.
891 * textprop.c (set_text_properties_1): Change while to do-while,
892 since the condition is always true at first.
894 * intervals.c (graft_intervals_into_buffer): Mark var as used.

898 * process.c (list_processes_1, create_pty, read_process_output):
899 (exec_sentinel): Remove vars that were set but not used.
900 (create_pty): Remove unnecessary "volatile"s.
901 (Fnetwork_interface_info): Avoid possibility of int overflow.
902 (read_process_output): Do adaptive read buffering even if carryover.

914 * print.c (print_error_message): Avoid int overflow.
916 * font.c (font_list_entities): Redo for clarity,
917 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
919 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
920 (font_score): Avoid potential overflow in diff calculation.

923 (sxhash): Redo loop for clarity and to avoid wraparound warning.
925 * eval.c (funcall_lambda): Rename local to avoid shadowing.
927 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
928 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
929 can always succeed if overflow has undefined behavior.
931 * search.c (boyer_moore, wordify): Remove vars set but not used.
932 (wordify): Omit three unnecessary tests.
934 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
935 All callers changed. This avoids the need for an unused var.
937 * casefiddle.c (casify_region): Remove var that is set but not used.
939 * dired.c (file_name_completion): Remove var that is set but not used.
941 * fileio.c (Finsert_file_contents): Make EOF condition clearer.

947 Check for integer overflow on size calculations.
949 * buffer.c (Fprevious_overlay_change): Remove var that is set
952 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
953 Remove vars that are set but not used.
954 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
955 (timer_check_2): Mark vars as initialized.
957 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.

969 Remove vars that are set but not used.
971 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
972 (make_invisible_cursor): Initialize a possibly-uninitialized variable.

990 (decode_coding_charset): Remove vars that are set but not used.
992 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
993 that is set but not used.
995 * print.c (print_object): Remove var that is set but not used.
997 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
998 The gnulib version avoids calling malloc in the usual case,
999 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
1000 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
1001 * filelock.c (current_lock_owner): Likewise.
1002 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

1026 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
1027 and thereabouts. All callers changed.
1028 (get_per_char_metric): Remove parameter `f', unused since
1029 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

1048 Add lexical binding.
1050 * window.c (Ftemp_output_buffer_show): New fun.
1051 (Fsave_window_excursion):

1054 * lread.c (lisp_file_lexically_bound_p): New function.
1055 (Fload): Bind Qlexical_binding.
1056 (readevalloop): Remove `evalfun' arg.
1057 Bind Qinternal_interpreter_environment.

1068 * image.c (parse_image_spec): Use Ffunctionp.
1070 * fns.c (concat, mapcar1): Accept byte-code-functions.
1072 * eval.c (Fsetq): Handle lexical vars.
1073 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
1074 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
1075 (FletX, Flet): Obey lexical binding.
1076 (Fcommandp): Handle closures.
1077 (Feval): New `lexical' arg.
1078 (eval_sub): New function extracted from Feval. Use it almost
1079 everywhere where Feval was used. Look up vars in lexical env.
1081 (Ffunctionp): Move from subr.el.
1082 (Ffuncall): Handle closures.
1083 (apply_lambda): Remove `eval_flags'.
1084 (funcall_lambda): Handle closures and new byte-code-functions.
1085 (Fspecial_variable_p): New function.
1086 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
1087 but without exporting it to Lisp.
1089 * doc.c (Fdocumentation, store_function_docstring):
1090 * data.c (Finteractive_form): Handle closures.
1092 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
1095 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN): New

1110 * xdisp.c (SCROLL_LIMIT): New macro.
1111 (try_scrolling): Use it when setting scroll_limit. Limit
1112 scrolling to 100 screen lines.
1113 (redisplay_window): Even when falling back on "recentering",
1114 position point in the window according to scroll-conservatively,
1115 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
1117 (try_scrolling): When point is above the window, allow searching
1118 as far as scroll_max, or one screenful, to compute vertical
1119 distance from PT to the scroll margin position. This prevents
1120 try_scrolling from unnecessarily failing when
1121 scroll-conservatively is set to a value slightly larger than the
1122 window height. Clean up the case of PT below the margin at bottom
1123 of window: scroll_max can no longer be INT_MAX. When aggressive
1124 scrolling is in use, don't let point enter the opposite scroll
1125 margin as result of the scroll.
1126 (syms_of_xdisp) <scroll-conservatively>: Document the
1127 threshold of 100 lines for never-recentering scrolling.

1135 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
1136 (redisplay_internal): Remove parameter `preserve_echo_area',
1137 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
1139 * indent.c (Fvertical_motion):
1140 * window.c (window_scroll_pixel_based, Frecenter):
1141 Don't pass `need_y_p' to `move_it_by_lines'.
1143 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
1145 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
1146 steal a few bits to be more compact.
1147 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
1148 Remove unneeded casts.
1150 * bytecode.c (Fbyte_code): CAR and CDR can GC.
1152 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
1154 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
1155 binding" message (bug#7967).
1157 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
1159 Fix more problems found by GCC 4.6.0's static checks.
1161 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
1162 Remove unused local var.
1164 * editfns.c (Fmessage_box): Remove unused local var.
1166 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
1167 (note_mode_line_or_margin_highlight, note_mouse_highlight):
1168 Omit unused local vars.
1169 * window.c (shrink_windows): Omit unused local var.
1170 * menu.c (digest_single_submenu): Omit unused local var.
1171 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
1172 Omit unused local var.
1174 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
1175 Don't assume string length fits in int.

1177 (read_key_sequence): Don't check last_real_key_start redundantly.
1179 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
1180 instead of alloca (Bug#8344).
1182 * eval.c (Fbacktrace): Don't assume nargs fits in int.

1194 * keyboard.c (syms_of_keyboard): Use the same style as later
1195 in this function when indexing through an array. This also
1196 works around GCC bug 48267.
1198 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
1200 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
1202 * chartab.c (sub_char_table_ref_and_range): Redo for slight
1203 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
1205 * keyboard.c, keyboard.h (num_input_events): Now size_t.
1206 This avoids undefined behavior on integer overflow, and is a bit
1207 more convenient anyway since it is compared to a size_t variable.
1209 Variadic C functions now count arguments with size_t, not int.
1210 This avoids an unnecessary limitation on 64-bit machines, which
1211 caused (substring ...) to crash on large vectors (Bug#8344).

1222 * frame.c (x_set_frame_parameters): Likewise.
1223 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
1224 0 if not found, not -1. All callers changed.
1226 * alloc.c (garbage_collect): Don't assume stack size fits in int.
1227 (stack_copy_size): Now size_t, not int.
1228 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
1230 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
1232 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
1233 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

1253 Vcommand_hook_internal.

1256 (funcall_nil, funcall_not): New functions.
1257 (run_hook_with_args): Call each function through a `funcall' argument.

1276 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
1277 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.

1350 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
1352 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
1353 incurred during fontification.

1416 * w32uniscribe.c (uniscribe_shape): Remove unused variable `nclusters'.
1417 (NOTHING): Remove unused static global variable.
1418 (uniscribe_check_otf): Remove unused variable `table'.
1419 (uniscribe_font_driver): Add missing initializers.
1421 2011-03-23 Julien Danjou <julien@danjou.info>
1423 * term.c (Fsuspend_tty, Fresume_tty):
1424 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
1425 * window.c (temp_output_buffer_show):
1426 * insdel.c (signal_before_change):
1427 * frame.c (Fhandle_switch_frame):
1428 * fileio.c (Fdo_auto_save):
1429 * emacs.c (Fkill_emacs):
1430 * editfns.c (save_excursion_restore):
1431 * cmds.c (internal_self_insert):
1432 * callint.c (Fcall_interactively):
1433 * buffer.c (Fkill_all_local_variables):
1434 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
1436 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
1437 unconditionnaly since it does the check itself.
1439 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
1441 Fix more problems found by GCC 4.5.2's static checks.
1443 * coding.c (encode_coding_raw_text): Avoid unnecessary test
1444 the first time through the loop, since we know p0 < p1 then.
1445 This also avoids a gcc -Wstrict-overflow warning.
1447 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
1448 leading to a memory leak, possible in functions like
1449 load_charset_map_from_file that can allocate an unbounded number
1450 of objects (Bug#8318).
1452 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
1453 that could (at least in theory) be that large.
1455 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
1456 This is less likely to overflow, and avoids undefined behavior if
1457 overflow does occur. All callers changed. Use strtoul to scan
1458 for the unsigned long integer.
1459 (pint2hrstr): Simplify and tune code slightly.
1460 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
1462 * scroll.c (do_scrolling): Work around GCC bug 48228.
1463 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

1466 This also avoids a warning with gcc -Wstrict-overflow.
1467 (validate_x_resource_name): Simplify count usage.
1468 This also avoids a warning with gcc -Wstrict-overflow.
1470 * fileio.c (Fcopy_file): Report error if fchown or fchmod
1473 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
1475 * process.c (Fmake_network_process): Use socklen_t, not int,
1476 where POSIX says socklen_t is required in portable programs.
1477 This fixes a porting bug on hosts like 64-bit HP-UX, where
1478 socklen_t is wider than int (Bug#8277).
1479 (Fmake_network_process, server_accept_connection):
1480 (wait_reading_process_output, read_process_output):
1483 * process.c: Rename or move locals to avoid shadowing.

1493 Make tparam.h and terminfo.c consistent.
1494 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
1495 Include tparam.h instead, since it declares them.
1496 * cm.h (PC): Remove extern decl; tparam.h now does this.
1497 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
1498 * terminfo.c: Include tparam.h, to check interfaces.
1499 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
1500 (tparam): Adjust signature to match interface in tparam.h;
1501 this removes some undefined behavior. Check that outstring and len
1502 are zero, which they always are with Emacs.
1503 * tparam.h (PC, BC, UP): New extern decls.
1505 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
1506 (xftfont_open): Rename locals to avoid shadowing.
1508 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
1509 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.

1524 (composition_update_it): Mark var as initialized.
1525 (find_automatic_composition): Mark vars as initialized,
1526 with a FIXME (Bug#8290).
1528 character.h: Rename locals to avoid shadowing.
1529 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
1530 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
1531 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
1532 (BUF_DEC_POS): Be more systematic about renaming local temporaries
1535 * textprop.c (property_change_between_p): Remove; unused.
1537 * intervals.c (interval_start_pos): Now static.
1539 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
1541 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
1542 Rename locals to avoid shadowing.
1544 * sound.c (wav_play, au_play, Fplay_sound_internal):
1545 Fix pointer signedness.
1546 (alsa_choose_format): Remove unused local var.
1547 (wav_play): Initialize a variable to 0, to prevent undefined
1548 behavior (Bug#8278).
1550 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
1552 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
1554 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
1555 clobbering (Bug#8298).
1556 * sysdep.c (sys_subshell): Likewise.
1557 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
1559 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
1560 This should get cleaned up, so that child_setup has the
1561 same signature on all platforms.
1563 * callproc.c (call_process_cleanup): Now static.
1564 (relocate_fd): Rename locals to avoid shadowing.
1566 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
1568 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
1569 not to be necessary, and produces flickering.
1571 2011-03-20 Glenn Morris <rgm@gnu.org>
1573 * config.in: Remove file.
1575 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
1577 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
1578 are now in src/globals.h.
1579 (syms_of_minibuf): Remove spurious & from previous change.
1581 2011-03-20 Leo <sdl.web@gmail.com>
1583 * minibuf.c (completing-read-function): New variable.
1584 (completing-read-default): Rename from completing-read.
1585 (completing-read): Call completing-read-function.
1587 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
1589 * xfaces.c (Fx_load_color_file):
1590 Read color file from absolute filename (bug#8250).
1592 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
1594 * makefile.w32-in: Update dependencies.
1596 2011-03-17 Eli Zaretskii <eliz@gnu.org>
1598 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.
1600 2011-03-17 Paul Eggert <eggert@cs.ucla.edu>

1605 (sigchld_handler): Now static.
1607 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
1608 That way, the code declares only the vars that it needs.
1609 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
1610 * s/cygwin.h (PTY_ITERATION): Likewise.
1611 * s/darwin.h (PTY_ITERATION): Likewise.
1612 * s/gnu-linux.h (PTY_ITERATION): Likewise.
1614 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
1615 * process.c (allocate_pty): Don't declare stb unless it's needed.
1617 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
1618 (CONSTANTLIM): Remove; unused.
1619 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
1620 Define only if needed.
1622 * unexelf.c (unexec): Name an expression,
1623 to avoid gcc -Wbad-function-cast warning.
1624 Use a different way to cause a compilation error if anyone uses
1625 n rather than nn, a way that does not involve shadowing.
1626 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
1628 * deps.mk (unexalpha.o): Remove; unused.
1630 New file unexec.h, the (simple) interface for unexec (Bug#8267).
1631 * unexec.h: New file.
1632 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
1633 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
1635 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
1636 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
1637 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.

1642 (back_comment, skip_chars): Mark vars as initialized.
1644 * character.h (FETCH_STRING_CHAR_ADVANCE_NO_CHECK, BUF_INC_POS):
1645 Rename locals to avoid shadowing.
1647 * lread.c (read1): Rewrite so as not to use empty "else".
1648 (Fload, readevalloop, read1): Rename locals to avoid shadowing.
1650 * print.c (Fredirect_debugging_output): Fix pointer signedess.
1652 * lisp.h (debug_output_compilation_hack): Add decl here, to avoid
1653 warning when compiling print.c.
1655 * font.c (font_unparse_fcname): Abort in an "impossible" situation
1656 instead of using an uninitialized var.
1657 (font_sort_entities): Mark var as initialized.
1659 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
1661 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

1676 * alloc.c (mark_backtrace): Move decl from here ...
1677 * lisp.h: ... to here, so that it can be checked.
1679 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
1680 (Fdefvar): Rewrite so as not to use empty "else".

1693 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
1694 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
1695 some of which prompt warnings from gcc -Wbad-function-cast.
1696 (Fformat_time_string, Fencode_time, Finsert_char):
1697 (Ftranslate_region_internal, Fformat):
1698 Rename or remove local vars to avoid shadowing.

1716 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
1717 Rename locals to avoid shadowing.
1718 (mark_stack): Move local variables into the #ifdef region where
1720 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
1721 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
1723 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
1724 (GC_STRING_CHARS): Remove; not used.
1725 (Fmemory_limit): Cast sbrk's returned value to char *.
1727 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
1728 avoids undefined behavior in theory.
1730 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
1732 Use functions, not macros, for up- and down-casing (Bug#8254).
1733 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
1734 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
1735 to use the following functions instead of these macros.
1736 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
1737 EMACS_INT, since callers assume the returned value fits in int.
1738 (upcase1): Likewise, for UPCASE_TABLE.
1739 (uppercasep, lowercasep, upcase): New static inline functions.
1740 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

1746 (regex_compile, re_search_2, re_match_2_internal):
1747 Remove unused local vars.
1748 (FREE_VAR): Rewrite so as not to use empty "else",
1749 which gcc can warn about.
1750 (regex_compile, re_match_2_internal): Mark locals as initialized.
1751 (RETALLOC_IF): Define only if needed.
1752 (WORDCHAR_P): Likewise. This one is never needed, but is used
1753 only in a comment talking about a compiler bug, so put inside
1754 the #if 0 of that comment.
1755 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
1756 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
1759 * search.c (boyer_moore): Rename locals to avoid shadowing.
1760 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
1761 (PREV_CHAR_BOUNDARY): Likewise.
1763 * search.c (simple_search): Remove unused var.
1765 * dired.c (compile_pattern): Move decl from here ...

1769 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
1771 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
1773 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):

1778 (casify_region): Mark local as initialized.
1780 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
1782 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
1783 New macros, so that the caller can use some names other than
1784 gcpro1, gcpro2, etc.
1785 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
1787 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
1788 argument, for consistency with GCPRO2_VAR, etc: it is now the
1789 prefix of the variable, not the variable itself. All uses
1791 * dired.c (directory_files_internal, file_name_completion):
1792 Rename locals to avoid shadowing.
1794 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
1795 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
1796 dired.c's scmp function, had undefined behavior.
1797 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
1798 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
1799 * buffer.h: ... to here, because these macros use current_buffer,
1800 and the new implementation with inline functions needs to have
1801 current_buffer in scope now, rather than later when the macros
1803 (downcase, upcase1): New static inline functions.
1804 (DOWNCASE, UPCASE1): Reimplement using these functions.
1805 This avoids undefined behavior in expressions like
1806 DOWNCASE (x) == DOWNCASE (y), which previously suffered
1807 from race conditions in accessing the global variables
1808 case_temp1 and case_temp2.
1809 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
1810 * lisp.h (case_temp1, case_temp2): Remove their decls.
1811 * character.h (ASCII_CHAR_P): Move from here ...
1812 * lisp.h: ... to here, so that the inline functions mentioned
1815 * dired.c (directory_files_internal_unwind): Now static.
1817 * fileio.c (file_name_as_directory, directory_file_name):
1818 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
1820 (file_name_as_directory): Use const pointers when appropriate.
1821 (Fexpand_file_name): Likewise. In particular, newdir might
1822 point at constant storage, so make it a const pointer.
1823 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
1824 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
1826 (Fset_file_times, Finsert_file_contents, auto_save_error):
1827 Rename locals to avoid shadowing.
1829 * minibuf.c (choose_minibuf_frame_1): Now static.
1830 (Ftry_completion, Fall_completions): Rename or remove locals
1833 * marker.c (bytepos_to_charpos): Remove; unused.
1835 * lisp.h (verify_bytepos, count_markers): New decls,
1836 so that gcc does not warn that these functions aren't declared.
1838 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
1839 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
1840 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
1841 (copy_text): Remove unused local var.
1843 * filelock.c (within_one_second): Now static.
1844 (lock_file_1): Rename local to avoid shadowing.
1846 * buffer.c (fix_overlays_before): Mark locals as initialized.
1847 (fix_start_end_in_overlays): Likewise. This function should be
1848 simplified by using pointers-to-pointers, but that's a different
1850 (switch_to_buffer_1): Now static.
1851 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
1852 (report_overlay_modification): Rename locals to avoid shadowing.
1854 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
1855 Fix pointer signedness issue.
1856 (sys_subshell): Mark local as volatile if checking for lint,
1857 to suppress a gcc -Wclobbered warning that does not seem to be right.
1858 (MAXPATHLEN): Define only if needed.
1860 * process.c (serial_open, serial_configure): Move decls from here ...
1861 * systty.h: ... to here, so that they can be checked.
1863 * fns.c (get_random, seed_random): Move extern decls from here ...
1864 * lisp.h: ... to here, so that they can be checked.
1866 * sysdep.c (reset_io): Now static.
1867 (wait_for_termination_signal): Remove; unused.
1869 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
1870 (copy_keymap_item, append_key, push_text_char_description):
1872 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
1873 (DENSE_TABLE_SIZE): Remove; unused.
1874 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
1875 (describe_map_tree):
1876 Rename locals to avoid shadowing.
1878 * keyboard.c: Declare functions static if they are not used elsewhere.
1879 (echo_char, echo_dash, cmd_error, top_level_2):
1880 (poll_for_input, handle_async_input): Now static.
1881 (read_char, kbd_buffer_get_event, make_lispy_position):
1882 (make_lispy_event, make_lispy_movement, apply_modifiers):
1883 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
1884 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
1885 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
