502 Accept 3 additional arguments needed by handle_display_spec.
503 This fixes incorrect cursor motion across display property with complex
504 values: lists, `(when COND...)' forms, etc.
505 (single_display_spec_string_p): Support property values that are
506 lists with the argument STRING its top-level element.
507 (display_prop_string_p): Fix the condition for processing a
508 property that is a list to be consistent with handle_display_spec.
509 (handle_display_spec): New function, refactored from the
510 last portion of handle_display_prop.
511 (compute_display_string_pos): Accept additional argument
512 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
513 value of a `display' property is a "replacing spec".
514 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
515 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
516 the display property, but just return a value indicating whether
517 the display property will replace the characters it covers.
518 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
519 frame_window_p members of struct bidi_it.
520 (compute_display_string_pos, compute_display_string_end):
522 (push_it): Accept second argument POSITION, where pop_it should
523 jump to continue iteration.
524 (reseat_1): Initialize bidi_it.disp_pos.
526 * keyboard.c (adjust_point_for_property): Adjust the call to
527 display_prop_intangible_p to its new signature.
529 * dispextern.h (struct bidi_it): New member frame_window_p.
530 (bidi_init_it): Update prototypes.
531 (display_prop_intangible_p): Update prototype.
532 (compute_display_string_pos, compute_display_string_end):
534 (struct bidi_it): New members nchars and disp_pos. ch_len is now
537 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
539 Malloc failure behavior now depends on size of allocation.
540 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
541 * lisp.h: Change signatures accordingly.
542 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
543 All callers changed. (Bug#8762)
545 * gnutls.c: Use Emacs's memory allocators.
546 Without this change, the gnutls library would invoke malloc etc.
547 directly, which causes problems on non-SYNC_INPUT hosts, and which
548 runs afoul of improving memory_full behavior. (Bug#8761)
549 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
550 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
551 xfree instead of the default malloc, realloc, free.
552 (Fgnutls_boot): No need to check for memory allocation failure,
553 since xmalloc does that for us.
555 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
556 * category.c (hash_get_category_set):
557 * ccl.c (ccl_driver):
558 * charset.c (Fdefine_charset_internal):
559 * charset.h (struct charset.hash_index):

565 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
566 (hashfn_equal, hashfn_user_defined, make_hash_table)
567 (maybe_resize_hash_table, hash_lookup, hash_put)
568 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
569 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
570 (Fsxhash, Fgethash, Fputhash, Fmaphash):
571 * image.c (make_image, search_image_cache, lookup_image)
572 (xpm_put_color_table_h):
573 * lisp.h (struct Lisp_Hash_Table):
574 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
575 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
576 for hashes and hash indexes, instead of 'unsigned' and 'int'.
577 * alloc.c (allocate_vectorlike):
578 Check for overflow in vector size calculations.
579 * ccl.c (ccl_driver):
580 Check for overflow when converting EMACS_INT to int.
581 * fns.c, image.c: Remove unnecessary static decls that would otherwise
582 need to be updated by these changes.
583 * fns.c (make_hash_table, maybe_resize_hash_table):
584 Check for integer overflow with large hash tables.
585 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
586 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
587 (SXHASH_REDUCE): New macro.
588 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
589 Use it instead of discarding useful hash info with large hash values.
590 (sxhash_float): New function.
591 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
592 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
593 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
594 Rewrite to use FIXNUM_BITS, as this simplifies things.
595 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
596 Adjust signatures to match updated version of code.
597 (consing_since_gc): Now EMACS_INT, since a single hash table can
598 use more than INT_MAX bytes.
600 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
602 Make it possible to build with GCC-4.6+ -O2 -flto.
604 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
606 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
608 * minibuf.c (get_minibuffer, read_minibuf_unwind):
609 Call minibuffer-inactive-mode.
611 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
613 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
616 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
618 * data.c (init_data): Remove code for UTS, this system is not
621 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
623 Don't force ./temacs to start in terminal mode.
625 * frame.c (make_initial_frame): Initialize faces in all cases, not
626 only when CANNOT_DUMP is defined.
627 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
629 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
631 * dispnew.c (add_window_display_history): Use const for the string
632 pointer. Remove declaration, not needed.
634 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
636 Use 'inline', not 'INLINE'.
637 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
638 * alloc.c, fontset.c (INLINE): Remove.
639 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
640 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
641 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
642 * gmalloc.c (register_heapinfo): Use inline unconditionally.
643 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
645 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
647 Make it possible to run ./temacs.
649 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
650 syms_of_callproc does the same thing. Remove test for
651 "initialized", do it in the caller.
652 * emacs.c (main): Avoid calling set_initial_environment when dumping.
654 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
656 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
657 (read_minibuf): Use get_minibuffer.
658 (syms_of_minibuf): Use DEFSYM.
659 (Qmetadata): New var.
660 * data.c (Qbuffer): Don't make it static.
661 (syms_of_data): Use DEFSYM.
663 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
665 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
666 (CCL_CODE_MIN): New macro.
668 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
670 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
672 * eval.c (Qdebug): Now static.
673 * lisp.h (Qdebug): Remove decl. This reverts a part of the
674 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
675 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
677 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
679 * image.c: Various fixes to ImageMagick code comments.
680 (Fimagemagick_types): Doc fix.
682 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
684 Minor fixes prompted by GCC 4.6.0 warnings.
686 * xselect.c (converted_selections, conversion_fail_tag): Now static.
688 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
689 (x_clipboard_manager_save_all): Move extern decl to ...
690 * xterm.h: ... here, so that it can be checked for consistency.
692 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
694 * xselect.c (x_clipboard_manager_save_frame)
695 (x_clipboard_manager_save_all): New functions.
696 (Fx_clipboard_manager_save): Lisp function deleted.
698 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
699 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
701 * xterm.h: Update prototype.
703 2011-05-28 William Xu <william.xwl@gmail.com>
705 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
708 2011-05-28 Jim Meyering <meyering@redhat.com>
710 Avoid a sign-extension bug in crypto_hash_function.
711 * fns.c (to_uchar): Define.
712 (crypto_hash_function): Use it to convert some newly-signed
713 variables to unsigned, to avoid sign-extension bugs. For example,
714 without this change, (md5 "truc") would evaluate to
715 45723a2aff78ff4fff7fff1114760e62 rather than the expected
716 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
717 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
719 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
721 Integer overflow fixes.
723 * dbusbind.c: Serial number integer overflow fixes.
724 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
725 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
726 to hold a serial number that is too large for a fixnum.
727 (Fdbus_method_return_internal, Fdbus_method_error_internal):
728 Check for serial numbers out of range. Decode any serial number
729 that was so large that it became a float. (Bug#8722)
731 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
732 (Fdbus_call_method, Fdbus_call_method_asynchronously):
733 Use XFASTINT rather than XUINT when numbers are nonnegative.
734 (xd_append_arg, Fdbus_method_return_internal):
735 (Fdbus_method_error_internal): Likewise. Also, for unsigned
736 arguments, check that Lisp number is nonnegative, rather than
737 silently wrapping negative numbers around. (Bug#8722)
738 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
741 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
743 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
745 ccl: add integer overflow checks
746 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
747 (IN_INT_RANGE): New macros.
748 (ccl_driver): Use them to check for integer overflow when
749 decoding a CCL program. Many of the new checks are whether XINT (x)
750 fits in int; it doesn't always, on 64-bit hosts. The new version
751 doesn't catch all possible integer overflows, but it's an
752 improvement. (Bug#8719)
754 * alloc.c (make_event_array): Use XINT, not XUINT.
755 There's no need for unsigned here.
757 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
758 This follows up to the 2011-05-06 change that substituted uintptr_t
759 for EMACS_INT. This case wasn't caught back then.
761 Rework Fformat to avoid integer overflow issues.
762 * editfns.c: Include <float.h> unconditionally, as it's everywhere
763 now (part of C89). Include <verify.h>.
764 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
765 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
766 (Fformat): Avoid the prepass trying to compute sizes; it was only
767 approximate and thus did not catch overflow reliably. Instead, walk
768 through the format just once, formatting and computing sizes as we go,
769 checking for integer overflow at every step, and allocating a larger
770 buffer as needed. Keep track separately whether the format is
771 multibyte. Keep only the most-recently calculated precision, rather
772 than them all. Record whether each argument has been converted to
773 string. Use EMACS_INT, not int, for byte and char and arg counts.
774 Support field widths and precisions larger than INT_MAX. Avoid
775 sprintf's undefined behavior with conversion specifications such as %#d
776 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
777 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
778 formatting out-of-range floating point numbers with int
781 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
783 * data.c: Avoid integer truncation in expressions involving floats.
784 * data.c: Include <intprops.h>.
785 (arith_driver): When there's an integer overflow in an expression
786 involving floating point, convert the integers to floating point
787 so that the resulting value does not suffer from catastrophic
788 integer truncation. For example, on a 64-bit host (* 4
789 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
790 Do not rely on undefined behavior after integer overflow.
792 merge count_size_as_multibyte, parse_str_to_multibyte
793 * character.c, character.h (count_size_as_multibyte):
794 Rename from parse_str_to_multibyte; all uses changed.
795 Check for integer overflow.
796 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
797 since it's now a duplicate of the other. This is more of
798 a character than a buffer op, so better that it's in character.c.
799 * fns.c, print.c: Adjust to above changes.
801 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
803 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
805 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
807 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
808 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
809 (x_clipboard_manager_save): Now static.
810 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
812 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
813 (crypto_hash_function): Now static.
814 Fix pointer signedness problems. Avoid unnecessary initializations.
816 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
818 * termhooks.h (Vselection_alist): Make it terminal-local.
820 * terminal.c (create_terminal): Initialize it.
822 * xselect.c: Support for clipboard managers.
823 (Vselection_alist): Move to termhooks.h as terminal-local var.
824 (LOCAL_SELECTION): New macro.
825 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
826 (symbol_to_x_atom): Remove gratuitous arg.
827 (x_handle_selection_request, lisp_data_to_selection_data)
828 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
829 (x_own_selection, x_get_local_selection, x_convert_selection):
830 New arg, specifying work frame. Use terminal-local Vselection_alist.
831 (some_frame_on_display): Delete unused function.
832 (Fx_own_selection_internal, Fx_get_selection_internal)
833 (Fx_disown_selection_internal, Fx_selection_owner_p)
834 (Fx_selection_exists_p): New optional frame arg.
835 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
836 (x_handle_selection_clear): Don't treat other terminals with the
837 same keyboard specially. Use the terminal-local Vselection_alist.
838 (x_clear_frame_selections): Use Frun_hook_with_args.
840 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
842 * xterm.h: Add support for those atoms.
844 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
846 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
847 (converted_selections, conversion_fail_tag): New global variables.
848 (x_selection_request_lisp_error): Free the above.
849 (x_get_local_selection): Remove unnecessary code.
850 (x_reply_selection_request): Args changed; handle arbitrary array
851 of converted selections stored in converted_selections.
852 Separate the XChangeProperty and SelectionNotify steps.
853 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
854 (x_convert_selection): New function.
855 (x_handle_selection_event): Simplify.
856 (x_get_foreign_selection): Don't ignore incoming requests while
857 waiting for an answer; this will fail when we implement
858 SAVE_TARGETS, and seems unnecessary anyway.
859 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
860 (Vx_sent_selection_functions): Doc fix.
862 2011-05-26 Leo Liu <sdl.web@gmail.com>
864 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)

870 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
871 for fringe update if it has periodic bitmap.
872 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
873 and fringe_bitmap_periodic_p.
875 * fringe.c (get_fringe_bitmap_data): New function.
876 (draw_fringe_bitmap_1, update_window_fringes): Use it.
877 (update_window_fringes): Record periodicity of fringe bitmap in glyph
878 row. Mark glyph row for fringe update if periodicity changed.
880 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
881 for fringe update unless it has periodic bitmap.
883 2011-05-25 Kenichi Handa <handa@m17n.org>
885 * xdisp.c (get_next_display_element): Set correct it->face_id for

936 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
938 * systime.h (Time): Define only if emacs is defined.
939 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
940 where the include path doesn't have X11/X.h by default. See
941 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.

975 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
977 * menu.c: Include limits.h (fixes the MS-Windows build broken by
980 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
982 Fix some integer overflow issues, such as string length overflow.
984 * insdel.c (count_size_as_multibyte): Check for string overflow.
986 * character.c (lisp_string_width): Check for string overflow.
987 Use EMACS_INT, not int, for string indexes and lengths; in
988 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
989 the resulting string length overflows an EMACS_INT; instead,
990 report a string overflow if no precision given. When checking for
991 precision exhaustion, use a check that cannot possibly have
992 integer overflow. (Bug#8675)
993 * character.h (lisp_string_width): Adjust to new signature.
995 * alloc.c (string_overflow): New function.
996 (Fmake_string): Use it. This doesn't change behavior, but saves
997 a few bytes and will simplify future changes.
998 * character.c (string_escape_byte8): Likewise.
999 * lisp.h (string_overflow): New decl.
1001 Fixups, following up to the user-interface timestamp change.
1002 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
1003 for UI timestamps, instead of unsigned long.
1004 * msdos.c (mouse_get_pos): Likewise.
1005 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
1006 * w32gui.h (Time): Define by including "systime.h" rather than by
1007 declaring it ourselves. (Bug#8664)
1009 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
1010 * image.c (clear_image_cache): Likewise.
1012 * term.c (term_mouse_position): Don't assume time_t wraparound.
1014 Be more systematic about user-interface timestamps.
1015 Before, the code sometimes used 'Time', sometimes 'unsigned long',
1016 and sometimes 'EMACS_UINT', to represent these timestamps.
1017 This change causes it to use 'Time' uniformly, as that's what X uses.
1018 This makes the code easier to follow, and makes it easier to catch
1019 integer overflow bugs such as Bug#8664.
1020 * frame.c (Fmouse_position, Fmouse_pixel_position):
1021 Use Time, not unsigned long, for user-interface timestamps.
1022 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
1023 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
1024 * keyboard.h (last_event_timestamp): Likewise.
1025 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
1026 * menu.h (xmenu_show): Likewise.
1027 * term.c (term_mouse_position): Likewise.
1028 * termhooks.h (struct input_event.timestamp): Likewise.
1029 (struct terminal.mouse_position_hook): Likewise.
1030 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
1031 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
1032 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
1033 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
1035 * menu.h, termhooks.h: Include "systime.h", for Time.
1037 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
1038 Don't assume that the difference between two unsigned long values
1039 can fit into an integer. At this point, we know button_down_time
1040 <= event->timestamp, so the difference must be nonnegative, so
1041 there's no need to cast the result if double-click-time is
1042 nonnegative, as it should be; check that it's nonnegative, just in
1043 case. This bug is triggered when events are more than 2**31 ms
1044 apart (about 25 days). (Bug#8664)
1046 * xselect.c (last_event_timestamp): Remove duplicate decl.
1047 (x_own_selection): Remove needless cast to unsigned long.
1049 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
1050 that always fit in int. Use a sentinel instead of a counter, to
1051 avoid a temp and to allay GCC's concerns about possible int overflow.
1052 * frame.h (struct frame): Use int for menu_bar_items_used
1053 instead of EMACS_INT, since it always fits in int.
1055 * menu.c (grow_menu_items): Check for int overflow.
1057 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
1059 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
1060 Before, the code was not consistent. These values cannot exceed
1061 2**31 - 1 so there's no need to make them unsigned.
1062 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
1063 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
1064 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
1066 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
1068 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
1069 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
1070 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
1071 presumably because the widths might not match.
1073 * window.c (size_window): Avoid needless test at loop start.
1075 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
1077 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
1079 2011-05-12 Drew Adams <drew.adams@oracle.com>
1081 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
1083 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1085 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
1086 `width' to `bar_area_x' and `bar_area_width', respectively.
1087 (x_scroll_run): Take account of fringe background extension.
1089 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
1090 Rename local vars `left' and `width' to `bar_area_x' and
1091 `bar_area_width', respectively.
1092 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
1093 background extension.
1095 2011-05-10 Jim Meyering <meyering@redhat.com>
1097 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
1099 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
1101 * image.c (Finit_image_library): Return t for built-in image types,
1102 like pbm and xbm. (Bug#8640)
1104 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
1106 * w32menu.c (set_frame_menubar): Fix submenu allocation.
1108 2011-05-07 Eli Zaretskii <eliz@gnu.org>
1110 * w32console.c (Fset_screen_color): Doc fix.
1111 (Fget_screen_color): New function.
1112 (syms_of_ntterm): Defsubr it.
1114 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
1115 unlink the temporary file if Fcall_process didn't create it in the
1117 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
1118 child process will be redirected to a file specified with `:file'.
1119 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
1120 cue to call_process_cleanup not to close that handle.
1122 2011-05-07 Ben Key <bkey76@gmail.com>
1124 * makefile.w32-in: The bootstrap-temacs rule now makes use of
1125 one of two shell specific rules, either bootstrap-temacs-CMD or
1126 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
1127 to the previous implementation of the bootstrap-temacs rule.
1128 The bootstrap-temacs-CMD rule is similar to the previous
1129 implementation of the bootstrap-temacs rule except that it
1130 makes use of the ESC_CFLAGS variable instead of the CFLAGS
1133 These changes, along with some changes to nt/configure.bat,
1134 nt/gmake.defs, and nt/nmake.defs, are required to extend my
1135 earlier fix to add support for --cflags and --ldflags options
1136 that include quotes so that it works whether make uses cmd or
1139 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
1141 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
1142 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
1144 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
1145 a string. Handle both cases.
1146 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
1147 (Fdbus_register_method): Use Qinvalid_function.
1149 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
1151 * makefile.w32-in: Update dependencies.
1152 (LISP_H): Add inttypes.h and stdin.h.
1153 (PROCESS_H): Add unistd.h.
1155 2011-05-06 Eli Zaretskii <eliz@gnu.org>
1157 * lread.c: Include limits.h (fixes the MS-Windows build broken by
1158 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
1160 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
1162 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
1164 * term.c (vfatal): Remove stray call to va_end.
1165 It's not needed and the C Standard doesn't allow it here anyway.
1167 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
1168 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
1170 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
1173 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
1175 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
1177 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
1179 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
1181 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
1183 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
1184 * charset.c (Fdefine_charset_internal): Don't initialize
1185 charset.code_space[15]. The value was garbage, on hosts with
1186 32-bit int (Bug#8600).
1188 * lread.c (read_integer): Be more consistent with string-to-number.
1189 Use string_to_number to do the actual conversion; this avoids
1190 rounding errors and fixes some other screwups. Without this fix,
1191 for example, #x1fffffffffffffff was misread as -2305843009213693952.
1192 (digit_to_number): Move earlier, for benefit of read_integer.
1193 Return -1 if the digit is out of range for the base, -2 if it is
1194 not a digit in any supported base. (Bug#8602)
1196 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
1198 * dispnew.c (scrolling_window): Return 1 if we scrolled,
1199 to match comment at start of function. This also removes a
1200 GCC warning about overflow in a 32+64-bit port.
1202 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
1204 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
1205 Reported by Stefan Monnier in
1206 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
1207 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
1208 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
1210 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
1211 (EMACS_UINTPTR): Likewise, with uintptr_t.
1213 * lisp.h: Prefer 64-bit EMACS_INT if available.
1214 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
1215 on 32-bit hosts that have 64-bit int, so that they can access
1217 However, temporarily disable this change unless the temporary
1218 symbol WIDE_EMACS_INT is defined.
1220 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
1222 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
1223 This removes an assumption that EMACS_INT and long are the same
1224 width as pointers. The assumption is true for Emacs porting targets
1225 now, but we want to make other targets possible.
1226 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
1227 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
1228 In the rest of the code, change types of integers that hold casted
1229 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
1230 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
1231 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
1232 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
1233 No need to cast type when ORing.
1234 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
1235 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
1236 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
1237 assume EMACS_INT is the same width as char *.
1238 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
1239 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
1240 Remove no-longer-needed casts.
1241 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
1242 (xg_tool_bar_help_callback, xg_make_tool_item):
1243 Use EMACS_INTPTR to hold an integer
1244 that will be cast to void *; this can avoid a GCC warning
1245 if EMACS_INT is not the same width as void *.
1246 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
1247 * xdisp.c (display_echo_area_1, resize_mini_window_1):
1248 (current_message_1, set_message_1):
1249 Use a local to convert to proper width without a cast.
1250 * xmenu.c (dialog_selection_callback): Likewise.
1252 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
1253 Also, don't assume VALBITS / RAND_BITS is less than 5,
1254 and don't rely on undefined behavior when shifting a 1 left into
1256 * lisp.h (get_random): Change signature to match.
1258 * lread.c (hash_string): Use size_t, not int, for hash computation.
1259 Normally we prefer signed values; but hashing is special, because
1260 it's better to use unsigned division on hash table sizes so that
1261 the remainder is nonnegative. Also, size_t is the natural width
1262 for hashing into memory. The previous code used 'int', which doesn't
1263 retain enough info to hash well into very large tables.
1264 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
1266 * dbusbind.c: Don't possibly lose pointer info when converting.
1267 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
1268 Use XPNTR rather than XHASH, so that the high-order bits of
1269 the pointer aren't lost when converting through void *.
1271 * eval.c (Fautoload): Don't double-shift a pointer.
1273 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
1275 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
1277 * gnutls.c (DEF_GNUTLS_FN):
1278 * image.c (DEF_IMGLIB_FN): Make function pointers static.
1280 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
1282 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
1285 2011-05-05 Eli Zaretskii <eliz@gnu.org>
1287 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
1288 New version that can reserve upto 2GB of heap space.
1290 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
1292 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
1294 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
1296 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
1297 `gnutls_certificate_set_x509_key_file'.
1299 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
1301 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
1302 Update dependencies.
1304 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
1306 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
1307 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
1308 Remove unused parameter `fildes'.
1309 * process.c (read_process_output, send_process): Don't pass it.
1311 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
1313 Fix previous change: the library cache is defined in w32.c.
1314 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
1315 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
1317 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
1319 Implement dynamic loading of GnuTLS on Windows.
1321 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
1322 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
1323 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
1326 * gnutls.c (Qgnutls_dll): Define.
1327 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
1328 (gnutls_*): Declare function pointers.
1329 (init_gnutls_functions): New function to initialize function pointers.
1330 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
1331 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
1332 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
1333 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
1334 (emacs_gnutls_write, emacs_gnutls_read)
1335 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
1336 (Fgnutls_available_p): New function.
1337 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
1338 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
1339 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
1341 * image.c: Include w32.h.
1342 (Vimage_type_cache): Delete.
1343 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
1344 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
1345 (w32_delayed_load): Move to w32.c.
1347 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
1349 * w32.c (QCloaded_from, Vlibrary_cache): Define.
1350 (w32_delayed_load): Move from image.c. When loading a library, record
1351 its filename in the :loaded-from property of the library id.
1352 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
1353 Initialize and staticpro them.
1354 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
1356 * process.c: Include lisp.h before w32.h, not after.
1357 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
1358 instead of gnutls_record_check_pending.
1360 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
1362 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
1364 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
1365 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
1368 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
1370 * xterm.c (x_set_frame_alpha): Do not set property on anything
1371 else than FRAME_X_OUTER_WINDOW (Bug#8608).
1373 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
1375 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
1377 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
1379 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
1380 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
1381 (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)
1382 (gnutls_global_initialized, Qgnutls_bootprop_priority)

1384 (Qgnutls_bootprop_callbacks, Qgnutls_bootprop_loglevel)
1385 (Qgnutls_bootprop_hostname, Qgnutls_bootprop_verify_flags)
1386 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
1387 (Qgnutls_bootprop_callbacks_verify): Make static.
1389 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
1391 * callproc.c: Indentation fixup.
1393 * sysdep.c (wait_for_termination_1): Make static.
1394 (wait_for_termination, interruptible_wait_for_termination):
1395 Move after wait_for_termination_1.
1397 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
1399 * sysdep.c (interruptible_wait_for_termination): New function
1400 which is like wait_for_termination, but allows keyboard
1403 * callproc.c (Fcall_process): Add (:file "file") as an option for
1405 (Fcall_process_region): Ditto.
1407 2011-04-30 Eli Zaretskii <eliz@gnu.org>
1409 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
1410 rather than `XVECTOR (FOO)->size'.
1412 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
1413 inttypes.h, as a gnulib replacement is used if it not available in

1418 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
1419 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
1420 of MOST_POSITIVE_FIXNUM. (Bug#8528)
1422 * coding.c (coding_alloc_by_realloc): Error out if destination
1423 will grow beyond MOST_POSITIVE_FIXNUM.
1424 (decode_coding_emacs_mule): Abort if there isn't enough place in
1425 charbuf for the composition carryover bytes. Reserve an extra
1426 space for up to 2 characters produced in a loop.
1427 (decode_coding_iso_2022): Abort if there isn't enough place in
1428 charbuf for the composition carryover bytes.
1430 2011-04-21 Eli Zaretskii <eliz@gnu.org>
1432 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
1433 aborting when %lld or %lll format is passed.
1434 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
1435 %llo or %llx format is passed. (Bug#8545)
1437 * window.c (window_scroll_line_based): Use a marker instead of
1438 simple variables to record original value of point. (Bug#7952)
1440 * doprnt.c (doprnt): Fix the case where a multibyte sequence
1441 produced by %s or %c overflows available buffer space. (Bug#8545)
1443 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
1445 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
1446 (SIZE_MAX): Move defn after all includes, as they might #define it.
1448 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
1450 * w32.c (init_environment): Warn about defaulting HOME to C:\.
1452 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
1454 * keyboard.c (Qdelayed_warnings_hook): Define.
1455 (command_loop_1): Run `delayed-warnings-hook'
1456 if Vdelayed_warnings_list is non-nil.
1457 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
1458 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
1460 2011-04-28 Eli Zaretskii <eliz@gnu.org>
1462 * doprnt.c (doprnt): Don't return value smaller than the buffer
1463 size if the message was truncated. (Bug#8545).
1465 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
1467 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
1468 (Fx_window_property): #if-0 the whole functions, not just the bodies.
1470 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
1472 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
1474 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
1476 * makefile.w32-in: Update dependencies.
1478 2011-04-27 Eli Zaretskii <eliz@gnu.org>
1480 Improve `doprnt' and its usage. (Bug#8545)
1481 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
1482 `format_end'. Remove support for %l as a conversion specifier.
1483 Don't use xrealloc. Improve diagnostics when the %l size modifier
1484 is used. Update the commentary.
1486 * eval.c (verror): Simplify calculation of size_t.
1488 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
1491 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
1493 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
1496 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
1498 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
1499 This makes this file independent of the recent pseudovector change.
1501 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
1503 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
1505 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
1506 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
1507 Remove unused local.
1508 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
1510 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
1511 GCC 4.6.0 optimizes based on type-based alias analysis.
1512 For example, if b is of type struct buffer * and v of type struct
1513 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
1514 != &v->size, and therefore "v->size = 1; b->size = 2; return
1515 v->size;" must therefore return 1. This assumption is incorrect
1516 for Emacs, since it type-puns struct Lisp_Vector * with many other
1517 types. To fix this problem, this patch adds a new type struct
1518 vectorlike_header that documents the constraints on layout of vectors
1519 and pseudovectors, and helps optimizing compilers not get fooled
1520 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
1521 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
1522 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
1524 (XSETPVECTYPE): Rewrite in terms of new macro.
1525 (XSETPVECTYPESIZE): New macro, specifying both type and size.
1526 This is a bit clearer, and further avoids the possibility of
1527 undesirable aliasing.
1528 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
1529 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
1530 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
1531 since Lisp_Subr is a special case (no "next" field).
1532 (ASIZE): Now uses header.size rather than size.
1533 All previous uses of XVECTOR (foo)->size replaced to use this macro,
1534 to avoid the hassle of writing XVECTOR (foo)->header.size.
1535 (struct vectorlike_header): New type.
1536 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
1537 object, to help avoid aliasing.
1538 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
1539 (SUBRP): Likewise, since Lisp_Subr is a special case.
1540 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
1541 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
1542 (struct Lisp_Hash_Table): Combine first two members into a single
1543 struct vectorlike_header member. All uses of "size" and "next" members
1544 changed to be "header.size" and "header.next".
1545 * buffer.h (struct buffer): Likewise.
1546 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
1547 * frame.h (struct frame): Likewise.
1548 * process.h (struct Lisp_Process): Likewise.
1549 * termhooks.h (struct terminal): Likewise.
1550 * window.c (struct save_window_data, struct saved_window): Likewise.
1551 * window.h (struct window): Likewise.
1552 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
1553 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
1554 * buffer.c (init_buffer_once): Likewise.
1555 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
1557 * process.c (Fformat_network_address): Use local var for size,
1560 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
1562 Make the Lisp reader and string-to-float more consistent (Bug#8525)
1563 * data.c (atof): Remove decl; no longer used or needed.
1564 (digit_to_number): Move to lread.c.
1565 (Fstring_to_number): Use new string_to_number function, to be
1566 consistent with how the Lisp reader treats infinities and NaNs.
1567 Do not assume that floating-point numbers represent EMACS_INT
1568 without losing information; this is not true on most 64-bit hosts.
1569 Avoid double-rounding errors, by insisting on integers when
1570 parsing non-base-10 numbers, as the documentation specifies.
1571 * lisp.h (string_to_number): New decl, replacing ...
1572 (isfloat_string): Remove.
1573 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
1574 (read1): Do not accept +. and -. as integers; this
1575 appears to have been a coding error. Similarly, do not accept
1576 strings like +-1e0 as floating point numbers. Do not report
1577 overflow for integer overflows unless the base is not 10 which
1578 means we have no simple and reliable way to continue.
1579 Break out the floating-point parsing into a new
1580 function string_to_number, so that Fstring_to_number parses
1581 floating point numbers consistently with the Lisp reader.
1582 (digit_to_number): Move here from data.c. Make it static inline.
1583 (E_CHAR, EXP_INT): Remove, replacing with ...
1584 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
1585 (string_to_number): New function, replacing isfloat_string.
1586 This function checks for valid syntax and produces the resulting
1587 Lisp float number too. Rework it so that string-to-number
1588 no longer mishandles examples like "1.0e+". Use strtoumax,
1589 so that overflow for non-base-10 numbers is reported only when
1590 there's no portable and simple way to convert to floating point.
1592 * textprop.c (set_text_properties_1): Rewrite for clarity,
1593 and to avoid GCC warning about integer overflow.
1595 * intervals.h (struct interval): Use EMACS_INT for members
1596 where EMACS_UINT might cause problems. See
1597 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
1598 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
1599 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
1601 (offset_intervals): Tell GCC not to worry about length overflow
1602 when negating a negative length.
1604 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
1605 (overrun_check_free): Likewise.
1607 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
1608 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
1611 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
1612 (gnutls_make_error): Rename local to avoid shadowing.
1613 (gnutls_emacs_global_deinit): ifdef out; not used.
1614 (Fgnutls_boot): Use const for pointer to readonly storage.
1615 Comment out unused local. Fix pointer signedness problems.
1617 * lread.c (openp): Don't stuff size_t into an 'int'.
1618 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
1619 about possible signed overflow.
1621 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
1622 (GDK_KEY_g): Don't define if already defined.
1623 (xg_prepare_tooltip): Avoid pointer signedness problem.
1624 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
1626 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
1627 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
1629 * xfns.c (Fx_window_property): Simplify a bit,
1630 to make a bit faster and to avoid GCC 4.6.0 warning.
1631 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
1633 * fns.c (internal_equal): Don't assume size_t fits in int.
1635 * alloc.c (compact_small_strings): Tighten assertion a little.
1637 Replace pEd with more-general pI, and fix some printf arg casts.
1638 * lisp.h (pI): New macro, generalizing old pEd macro to other
1639 conversion specifiers. For example, use "...%"pI"d..." rather
1640 than "...%"pEd"...".
1641 (pEd): Remove. All uses replaced with similar uses of pI.
1642 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
1643 * alloc.c (check_pure_size): Don't overflow by converting size to int.
1644 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
1645 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
1646 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
1647 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
1648 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
1650 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
1651 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
1652 * print.c (safe_debug_print, print_object): Likewise.
1653 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
1655 Use pI instead of if-then-else-abort. Use %p to avoid casts,
1656 avoiding the 0 flag, which is not portable.
1657 * process.c (Fmake_network_process): Use pI to avoid cast.
1658 * region-cache.c (pp_cache): Likewise.
1659 * xdisp.c (decode_mode_spec): Likewise.
1660 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
1661 behavior on 64-bit hosts with printf arg.
1662 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
1663 (x_stop_queuing_selection_requests): Likewise.
1664 (x_get_window_property): Don't truncate byte count to an 'int'
1667 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
1668 here, since it parses constructs like leading '-' and spaces,
1669 which are not wanted; and it overflows with large numbers.
1670 Instead, simply match F[0-9]+, which is what is wanted anyway.
1672 * alloc.c: Remove unportable assumptions about struct layout.
1673 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
1674 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
1675 (allocate_vectorlike, make_pure_vector): Use the new macros,
1676 plus offsetof, to remove unportable assumptions about struct layout.
1677 These assumptions hold on all porting targets that I know of, but
1678 they are not guaranteed, they're easy to remove, and removing them
1679 makes further changes easier.
1681 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
1682 This doesn't fix a bug but makes the code clearer.
1683 (string_overrun_cookie): Now const. Use initializers that
1684 don't formally overflow signed char, to avoid warnings.
1685 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
1686 can cause Emacs to crash when string overrun checking is enabled.
1687 (allocate_buffer): Don't assume sizeof (struct buffer) is a
1688 multiple of sizeof (EMACS_INT); it need not be, if
1689 alignof(EMACS_INT) < sizeof (EMACS_INT).
1690 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
1692 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
1694 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
1696 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
1698 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
1699 supposed to be handshaking. (Bug#8556)
1700 Reported by Paul Eggert <eggert@cs.ucla.edu>.
1702 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

1705 * eval.c (Qdebug): Restore global linkage.
1706 * keyboard.c (debug-on-event): New variable.
1707 (handle_user_signal): Break into debugger when debug-on-event
1708 matches the current signal symbol.

1712 * alloc.c (check_sblock, check_string_bytes)
1713 (check_string_free_list): Convert to standard C.
1715 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
1717 * w32.c (emacs_gnutls_push): Fix typo.
1719 2011-04-25 Eli Zaretskii <eliz@gnu.org>
1721 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
1722 "cast to pointer from integer of different size".
1724 Improve doprnt and its use in verror. (Bug#8545)
1725 * doprnt.c (doprnt): Document the set of format control sequences
1726 supported by the function. Use SAFE_ALLOCA instead of always
1729 * eval.c (verror): Don't limit the buffer size at size_max-1, that
1730 is one byte too soon. Don't use xrealloc; instead xfree and
1733 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
1735 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
1738 * gnutls.c: Renamed global_initialized to
1739 gnutls_global_initialized. Added internals for the
1740 :verify-hostname-error, :verify-error, and :verify-flags
1741 parameters of `gnutls-boot' and documented those parameters in the
1742 docstring. Start callback support.
1743 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
1744 unless a fatal error occured. Call gnutls_alert_send_appropriate
1745 on error. Return error code.
1746 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
1747 (emacs_gnutls_read): Likewise.
1748 (Fgnutls_boot): Return handshake error code.
1749 (emacs_gnutls_handle_error): New function.
1750 (wsaerror_to_errno): Likewise.
1752 * w32.h (emacs_gnutls_pull): Add prototype.

1817 * doprnt.c: Include limits.h.
1818 (SIZE_MAX): New macro.
1819 (doprnt): Return a size_t value. 2nd arg is now size_t.
1820 Many local variables are now size_t instead of int or unsigned.
1821 Improve overflow protection. Support `l' modifier for integer
1822 conversions. Support %l conversion. Don't assume an EMACS_INT
1823 argument for integer conversions and for %c.
1825 * lisp.h (doprnt): Restore prototype.
1827 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
1830 * Makefile.in (base_obj): Add back doprnt.o.
1832 * deps.mk (doprnt.o): Add back prerequisites.
1833 (callint.o): Depend on character.h.
1835 * eval.c (internal_lisp_condition_case): Include the handler
1836 representation in the error message.
1837 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
1838 when breaking from the loop.
1840 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
1842 * callint.c (Fcall_interactively): When displaying error message
1843 about invalid control letter, pass the character's codepoint, not
1844 a pointer to its multibyte form. Improve display of the character
1845 in octal and display also its hex code.
1847 * character.c (char_string): Use %x to display the (unsigned)
1848 codepoint of an invalid character, to avoid displaying a bogus
1851 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
1852 `error', not SYMBOL_NAME itself.
1854 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
1855 character arguments to `error'.
1857 * charset.c (check_iso_charset_parameter): Fix incorrect argument
1858 to `error' in error message about FINAL_CHAR argument. Make sure
1859 FINAL_CHAR is a character, and use %c when it is passed as
1860 argument to `error'.
1862 2011-04-23 Eli Zaretskii <eliz@gnu.org>
1864 * s/ms-w32.h (localtime): Redirect to sys_localtime.
1866 * w32.c: Include <time.h>.

2408 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
2409 so that it's not optimized away.
2410 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
2411 * dispextern.h (bidi_dump_cached_states): Remove, since it's
2412 exported only to the debugger.
2414 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
2415 * atimer.h (run_all_atimers): Remove; not exported.
2417 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
2418 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
2419 was inaccessible from Lisp.
2420 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
2421 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
2423 alloc.c: Import and export fewer symbols, and remove unused items.
2424 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
2426 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
2427 it's not optimized away by whole-program optimization.

2435 (n_float_blocks, float_free_list, cons_block, cons_block_index):
2436 (cons_free_list, last_marked_index):

2440 (mark_backtrace): Define only if BYTE_MARK_STACK.
2441 * xdisp.c (message_enable_multibyte): Now static.
2443 Declare Lisp_Object Q* variables to be 'static' if not exported.
2444 This makes it easier for human readers (and static analyzers)
2445 to see whether these variables are used from other modules.
2446 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
2447 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
2448 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

2456 Remove decls of unexported vars.
2457 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
2459 * lisp.h (DEFINE_FUNC): Make sname 'static'.
2461 Make Emacs functions such as Fatom 'static' by default.
2462 This makes it easier for human readers (and static analyzers)
2463 to see whether these functions can be called from other modules.
2464 DEFUN now defines a static function. To make the function external
2465 so that it can be used in other C modules, use the new macro DEFUE.
2466 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
2467 (Finit_image_library):
2468 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
2469 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
2470 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
2471 Remove decls, since these functions are now static.
2472 (Funintern, Fget_internal_run_time): New decls, since these functions
2473 were already external.

2482 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
2483 Mark functions with DEFUE instead of DEFUN,
2484 if they are used in other modules.

2486 decls for now-static functions.
2487 * buffer.h (Fdelete_overlay): Remove decl.

2526 when at ZV. (Bug#8487)
2528 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
2530 * charset.c (Fclear_charset_maps): Use xfree instead of free.
2532 * keyboard.c (parse_tool_bar_item): Likewise.
2533 * sound.c (sound_cleanup, alsa_close): Likewise.
2534 * termcap.c (tgetent): Likewise.
2535 * xfns.c (x_default_font_parameter): Likewise.

2538 * alloc.c (overrun_check_malloc, overrun_check_realloc)
2539 (overrun_check_free): Protoize.
2541 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
2543 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
2544 since callers should never pass a negative size.
2545 Change the signature to match that of plain 'read' and 'write'; see
2546 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
2547 * lisp.h: Update prototypes of emacs_write and emacs_read.
2549 2011-04-11 Eli Zaretskii <eliz@gnu.org>
2551 * xdisp.c (redisplay_window): Don't try to determine the character
2552 position of the scroll margin if the window start point w->startp
2553 is outside the buffer's accessible region. (Bug#8468)
2555 2011-04-10 Eli Zaretskii <eliz@gnu.org>
2557 Fix write-region and its subroutines for buffers > 2GB.
2558 * fileio.c (a_write, e_write): Modify declaration of arguments and
2559 local variables to support buffers larger than 2GB.
2560 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
2562 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
2563 argument, local variables, and return value.
2565 * lisp.h: Update prototypes of emacs_write and emacs_read.
2567 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
2569 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
2571 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
2573 Fix more problems found by GCC 4.6.0's static checks.
2575 * xdisp.c (vmessage): Use a better test for character truncation.
2577 * charset.c (load_charset_map): <, not <=, for optimization,
2578 and to avoid potential problems with integer overflow.
2579 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
2580 * casetab.c (set_identity, shuffle): Likewise.
2581 * editfns.c (Fformat): Likewise.
2582 * syntax.c (skip_chars): Likewise.
2584 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
2585 This also lets GCC 4.6.0 generate slightly better loop code.
2587 * callint.c (Fcall_interactively): <, not <=, for optimization.
2588 (Fcall_interactively): Count the number of arguments produced,
2589 not the number of arguments given. This is simpler and lets GCC
2590 4.6.0 generate slightly better code.
2592 * ftfont.c: Distingish more carefully between FcChar8 and char.
2593 The previous code passed unsigned char * to a functions like
2594 strlen and xstrcasecmp that expect char *, which does not
2595 conform to the C standard.
2596 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
2597 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
2598 char * when the C standard requires it.
2600 * keyboard.c (read_char): Remove unused var.
2602 * eval.c: Port to Windows vsnprintf (Bug#8435).
2604 (SIZE_MAX): Define if the headers do not.
2605 (verror): Do not give up if vsnprintf returns a negative count.
2606 Instead, grow the buffer. This ports to Windows vsnprintf, which
2607 does not conform to C99. Problem reported by Eli Zaretskii.
2608 Also, simplify the allocation scheme, by avoiding the need for
2609 calling realloc, and removing the ALLOCATED variable.
2611 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
2613 Remove invocations of doprnt, as Emacs now uses vsnprintf.
2614 But keep the doprint source code for now, as we might revamp it
2615 and use it again (Bug#8435).
2616 * lisp.h (doprnt): Remove.
2617 * Makefile.in (base_obj): Remove doprnt.o.
2618 * deps.mk (doprnt.o): Remove.
2620 error: Print 32- and 64-bit integers portably (Bug#8435).
2621 Without this change, on typical 64-bit hosts error ("...%d...", N)
2622 was used to print both 32- and 64-bit integers N, which relied on
2624 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
2626 * lisp.h (error, verror): Mark as printf-like functions.
2627 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
2628 Report overflow in size calculations when allocating printf buffer.
2629 Do not truncate output string at its first null byte.
2630 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
2631 Truncate the output at a character boundary, since vsnprintf does not
2633 * charset.c (check_iso_charset_parameter): Convert internal
2634 character to string before calling 'error', since %c now has the
2636 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
2637 overflow when computing char to be passed to 'error'. Do not
2638 pass Lisp_Object to 'error'; pass the integer instead.
2639 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
2640 formatted with plain %d.
2642 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
2644 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
2646 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
2648 * xterm.c (x_catch_errors): Remove duplicate declaration.
2650 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
2652 * xdisp.c, lisp.h (message_nolog): Remove; unused.
2654 2011-04-10 Jim Meyering <meyering@redhat.com>
2656 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
2657 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
2658 return ssize_t not "int", and use size_t as the buffer length.
2659 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
2660 * gnutls.h: Update declarations.
2661 * process.c (read_process_output): Use ssize_t, to match.
2662 (send_process): Likewise.
2664 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
2666 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
2668 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
2670 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
2671 Use unsigned char, to match FcChar8 type definition.
2673 * xterm.c (handle_one_xevent):
2674 * xmenu.c (create_and_show_popup_menu):
2675 * xselect.c (x_decline_selection_request)
2676 (x_reply_selection_request): Avoid type-punned deref of X events.
2678 2011-04-09 Eli Zaretskii <eliz@gnu.org>
2680 Fix some uses of `int' instead of EMACS_INT.
2681 * search.c (string_match_1, fast_string_match)
2682 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
2683 (scan_buffer, find_next_newline_no_quit)
2684 (find_before_next_newline, search_command, Freplace_match)
2685 (Fmatch_data): Make some `int' variables be EMACS_INT.
2687 * xdisp.c (display_count_lines): 3rd argument and return value now
2688 EMACS_INT. All callers changed.
2689 (pint2hrstr): Last argument is now EMACS_INT.
2691 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
2692 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
2693 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

2696 (decode_coding_ccl, decode_coding_charset)
2697 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.

2699 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
2700 <char_offset, last_offset>: Declare EMACS_INT.

2705 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
2707 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
2708 (encode_invocation_designation): Last argument P_NCHARS is now
2710 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
2711 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
2713 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
2716 * ccl.c (Fccl_execute_on_string): Declare some variables
2719 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)

2731 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
2733 * keyboard.c (read_char): Call Lisp function help-form-show,
2734 instead of using internal_with_output_to_temp_buffer.

2736 (syms_of_keyboard): Use DEFSYM macro.
2738 * print.c (internal_with_output_to_temp_buffer): Function deleted.

2751 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
2753 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
2755 Fix more problems found by GCC 4.6.0's static checks.
2757 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
2759 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
2761 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
2763 * xdisp.c (vmessage): Mark as a printf-like function.
2765 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
2767 * sound.c (sound_warning): Don't crash if arg contains a printf format.
2769 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
2770 printf-like functions.
2771 (tiff_load): Add casts to remove these marks before passing them
2772 to system-supplied API.
2774 * eval.c (Fsignal): Remove excess argument to 'fatal'.
2776 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
2777 This avoids several warnings with gcc -Wstrict-overflow.
2778 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
2779 directly, rather than having caller test rule sign. This avoids
2780 some unnecessary tests.
2781 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
2782 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
2783 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.

2797 by using the new macro.
2799 * textprop.c (set_text_properties_1): Change while to do-while,
2800 since the condition is always true at first.

2803 (interval_deletion_adjustment): Return unsigned value.
2806 * process.c (list_processes_1, create_pty, read_process_output):

2835 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
2836 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
2837 can always succeed if overflow has undefined behavior.
2839 * search.c (boyer_moore, wordify): Remove vars set but not used.
2840 (wordify): Omit three unnecessary tests.
2842 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
2843 All callers changed. This avoids the need for an unused var.
2845 * casefiddle.c (casify_region): Remove var that is set but not used.
2847 * dired.c (file_name_completion): Remove var that is set but not used.
2849 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
2851 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
2852 (Finsert_file_contents): Remove unnecessary code checking fd.
2854 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
2855 Check for integer overflow on size calculations.

2867 * image.c (lookup_image): Remove var that is set but not used.
2868 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
2870 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
2871 that are set but not used.
2873 * xfns.c (make_invisible_cursor): Don't return garbage
2874 if XCreateBitmapFromData fails (Bug#8410).
2876 * xselect.c (x_get_local_selection, x_handle_property_notify):
2877 Remove vars that are set but not used.
2879 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
2880 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
2882 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
2883 Remove var that is set but not used.
2884 (scroll_bar_windows_size): Now size_t, not int.
2885 (x_send_scroll_bar_event): Use size_t, not int, for sizes.

2894 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
2895 All callers changed.
2896 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
2897 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
2898 (decode_coding_charset): Remove vars that are set but not used.
2900 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
2901 that is set but not used.
2903 * print.c (print_object): Remove var that is set but not used.
2905 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
2906 The gnulib version avoids calling malloc in the usual case,
2907 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
2908 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
2909 * filelock.c (current_lock_owner): Likewise.
2910 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
2911 * sysdep.c: Include allocator.h, careadlinkat.h.
2912 (emacs_no_realloc_allocator): New static constant.
2913 (emacs_readlink): New function.
2914 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on

2919 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
2920 first non-nil return value).

2934 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
2935 and thereabouts. All callers changed.
2936 (get_per_char_metric): Remove parameter `f', unused since
2937 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

2949 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
2951 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
2954 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
2956 Add lexical binding.
2958 * window.c (Ftemp_output_buffer_show): New fun.
2959 (Fsave_window_excursion):
2960 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
2962 * lread.c (lisp_file_lexically_bound_p): New function.
2963 (Fload): Bind Qlexical_binding.
2964 (readevalloop): Remove `evalfun' arg.
2965 Bind Qinternal_interpreter_environment.
2966 (Feval_buffer): Bind Qlexical_binding.
2967 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
2969 (syms_of_lread): Declare `lexical-binding'.
2971 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
2973 * keyboard.c (eval_dyn): New fun.
2974 (menu_item_eval_property): Use it.
2976 * image.c (parse_image_spec): Use Ffunctionp.
2978 * fns.c (concat, mapcar1): Accept byte-code-functions.
2980 * eval.c (Fsetq): Handle lexical vars.
2981 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
2982 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
2983 (FletX, Flet): Obey lexical binding.
2984 (Fcommandp): Handle closures.
2985 (Feval): New `lexical' arg.
2986 (eval_sub): New function extracted from Feval. Use it almost
2987 everywhere where Feval was used. Look up vars in lexical env.
2989 (Ffunctionp): Move from subr.el.
2990 (Ffuncall): Handle closures.
2991 (apply_lambda): Remove `eval_flags'.
2992 (funcall_lambda): Handle closures and new byte-code-functions.
2993 (Fspecial_variable_p): New function.
2994 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
2995 but without exporting it to Lisp.
2997 * doc.c (Fdocumentation, store_function_docstring):
2998 * data.c (Finteractive_form): Handle closures.
3000 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
3003 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
3005 (exec_byte_code): New function extracted from Fbyte_code to handle new
3006 calling convention for byte-code-functions. Add new byte-codes.
3008 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
3010 * alloc.c (Fmake_symbol): Init new `declared_special' field.
3012 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
3014 * xdisp.c (redisplay_internal): Fix prototype.

3018 * xdisp.c (SCROLL_LIMIT): New macro.
3019 (try_scrolling): Use it when setting scroll_limit.
3020 Limit scrolling to 100 screen lines.
3021 (redisplay_window): Even when falling back on "recentering",
3022 position point in the window according to scroll-conservatively,
3023 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
3025 (try_scrolling): When point is above the window, allow searching
3026 as far as scroll_max, or one screenful, to compute vertical
3027 distance from PT to the scroll margin position. This prevents
3028 try_scrolling from unnecessarily failing when
3029 scroll-conservatively is set to a value slightly larger than the
3030 window height. Clean up the case of PT below the margin at bottom
3031 of window: scroll_max can no longer be INT_MAX. When aggressive
3032 scrolling is in use, don't let point enter the opposite scroll
3033 margin as result of the scroll.
3034 (syms_of_xdisp) <scroll-conservatively>: Document the
3035 threshold of 100 lines for never-recentering scrolling.

3042 (message_log_check_duplicate): Remove parameters `prev_bol' and
3043 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
3044 (redisplay_internal): Remove parameter `preserve_echo_area',
3045 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
3047 * indent.c (Fvertical_motion):
3048 * window.c (window_scroll_pixel_based, Frecenter):
3049 Don't pass `need_y_p' to `move_it_by_lines'.
3051 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
3053 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
3054 steal a few bits to be more compact.
3055 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
3056 Remove unneeded casts.
3058 * bytecode.c (Fbyte_code): CAR and CDR can GC.
3060 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
3062 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
3063 binding" message (bug#7967).
3065 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
3067 Fix more problems found by GCC 4.6.0's static checks.
3069 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
3070 Remove unused local var.
3072 * editfns.c (Fmessage_box): Remove unused local var.
3074 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
3075 (note_mode_line_or_margin_highlight, note_mouse_highlight):
3076 Omit unused local vars.
3077 * window.c (shrink_windows): Omit unused local var.
3078 * menu.c (digest_single_submenu): Omit unused local var.
3079 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
3080 Omit unused local var.
3082 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
3083 Don't assume string length fits in int.
3084 (keyremap_step, read_key_sequence): Use size_t for sizes.
3085 (read_key_sequence): Don't check last_real_key_start redundantly.
3087 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
3088 instead of alloca (Bug#8344).
3090 * eval.c (Fbacktrace): Don't assume nargs fits in int.

3093 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
3095 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
3098 * term.c (produce_glyphless_glyph): Remove unnecessary test.
3100 * cm.c (calccost): Turn while-do into do-while, for clarity.
3102 * keyboard.c (syms_of_keyboard): Use the same style as later
3103 in this function when indexing through an array. This also
3104 works around GCC bug 48267.
3106 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
3108 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
3110 * chartab.c (sub_char_table_ref_and_range): Redo for slight
3111 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
3113 * keyboard.c, keyboard.h (num_input_events): Now size_t.
3114 This avoids undefined behavior on integer overflow, and is a bit
3115 more convenient anyway since it is compared to a size_t variable.
3117 Variadic C functions now count arguments with size_t, not int.
3118 This avoids an unnecessary limitation on 64-bit machines, which
3119 caused (substring ...) to crash on large vectors (Bug#8344).
3120 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.

3130 * frame.c (x_set_frame_parameters): Likewise.
3131 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
3132 0 if not found, not -1. All callers changed.
3134 * alloc.c (garbage_collect): Don't assume stack size fits in int.
3135 (stack_copy_size): Now size_t, not int.
3136 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
3138 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
3140 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
3141 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
3142 All callers changed.
3144 * lisp.h (multibyte_char_to_unibyte):

3157 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
3158 don't set the hook to nil, but remove the offending function instead.
3159 (Qcommand_hook_internal): Remove, unused.
3160 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
3161 Vcommand_hook_internal.

3164 (funcall_nil, funcall_not): New functions.
3165 (run_hook_with_args): Call each function through a `funcall' argument.

3180 All callers changed.
3182 * w32.c (_wsa_errlist): Use braces for struct initializers.
3184 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
3185 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
3186 All callers changed.

3329 2011-03-23 Julien Danjou <julien@danjou.info>
3331 * term.c (Fsuspend_tty, Fresume_tty):
3332 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
3333 * window.c (temp_output_buffer_show):
3334 * insdel.c (signal_before_change):
3335 * frame.c (Fhandle_switch_frame):
3336 * fileio.c (Fdo_auto_save):
3337 * emacs.c (Fkill_emacs):
3338 * editfns.c (save_excursion_restore):
3339 * cmds.c (internal_self_insert):
3340 * callint.c (Fcall_interactively):
3341 * buffer.c (Fkill_all_local_variables):
3342 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
3344 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
3345 unconditionnaly since it does the check itself.
3347 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
3349 Fix more problems found by GCC 4.5.2's static checks.
3351 * coding.c (encode_coding_raw_text): Avoid unnecessary test
3352 the first time through the loop, since we know p0 < p1 then.
3353 This also avoids a gcc -Wstrict-overflow warning.
3355 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
3356 leading to a memory leak, possible in functions like
3357 load_charset_map_from_file that can allocate an unbounded number
3358 of objects (Bug#8318).
3360 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
3361 that could (at least in theory) be that large.
3363 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
3364 This is less likely to overflow, and avoids undefined behavior if
3365 overflow does occur. All callers changed. Use strtoul to scan
3366 for the unsigned long integer.
3367 (pint2hrstr): Simplify and tune code slightly.
3368 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
3370 * scroll.c (do_scrolling): Work around GCC bug 48228.
3371 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

3376 This also avoids a warning with gcc -Wstrict-overflow.
3378 * fileio.c (Fcopy_file): Report error if fchown or fchmod
3381 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
3383 * process.c (Fmake_network_process): Use socklen_t, not int,
3384 where POSIX says socklen_t is required in portable programs.
3385 This fixes a porting bug on hosts like 64-bit HP-UX, where
3386 socklen_t is wider than int (Bug#8277).
3387 (Fmake_network_process, server_accept_connection):
3388 (wait_reading_process_output, read_process_output):
3391 * process.c: Rename or move locals to avoid shadowing.

3401 Make tparam.h and terminfo.c consistent.
3402 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
3403 Include tparam.h instead, since it declares them.
3404 * cm.h (PC): Remove extern decl; tparam.h now does this.
3405 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
3406 * terminfo.c: Include tparam.h, to check interfaces.
3407 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
3408 (tparam): Adjust signature to match interface in tparam.h;
3409 this removes some undefined behavior. Check that outstring and len
3410 are zero, which they always are with Emacs.
3411 * tparam.h (PC, BC, UP): New extern decls.
3413 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
3414 (xftfont_open): Rename locals to avoid shadowing.
3416 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

3432 (composition_update_it): Mark var as initialized.
3433 (find_automatic_composition): Mark vars as initialized,
3434 with a FIXME (Bug#8290).
3436 character.h: Rename locals to avoid shadowing.

3439 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
3440 (BUF_DEC_POS): Be more systematic about renaming local temporaries
3443 * textprop.c (property_change_between_p): Remove; unused.
3445 * intervals.c (interval_start_pos): Now static.
3447 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

3450 Rename locals to avoid shadowing.
3452 * sound.c (wav_play, au_play, Fplay_sound_internal):
3453 Fix pointer signedness.
3454 (alsa_choose_format): Remove unused local var.
3455 (wav_play): Initialize a variable to 0, to prevent undefined
3456 behavior (Bug#8278).
3458 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
3460 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
3462 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
3463 clobbering (Bug#8298).
3464 * sysdep.c (sys_subshell): Likewise.
3465 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
3467 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
3468 This should get cleaned up, so that child_setup has the
3469 same signature on all platforms.
3471 * callproc.c (call_process_cleanup): Now static.
3472 (relocate_fd): Rename locals to avoid shadowing.
3474 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
3476 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
3477 not to be necessary, and produces flickering.
3479 2011-03-20 Glenn Morris <rgm@gnu.org>
3481 * config.in: Remove file.
3483 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
3485 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
3486 are now in src/globals.h.
3487 (syms_of_minibuf): Remove spurious & from previous change.
3489 2011-03-20 Leo <sdl.web@gmail.com>
3491 * minibuf.c (completing-read-function): New variable.
3492 (completing-read-default): Rename from completing-read.
3493 (completing-read): Call completing-read-function.
3495 2011-03-19 Juanma Barranquero <lekktu@gmail.com>

3498 Read color file from absolute filename (bug#8250).
3500 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
3502 * makefile.w32-in: Update dependencies.
3504 2011-03-17 Eli Zaretskii <eliz@gnu.org>
3506 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

3513 (sigchld_handler): Now static.
3515 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
3516 That way, the code declares only the vars that it needs.
3517 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
3518 * s/cygwin.h (PTY_ITERATION): Likewise.
3519 * s/darwin.h (PTY_ITERATION): Likewise.

3522 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
3523 * process.c (allocate_pty): Don't declare stb unless it's needed.
3525 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
3526 (CONSTANTLIM): Remove; unused.
3527 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
3528 Define only if needed.
3530 * unexelf.c (unexec): Name an expression,
3531 to avoid gcc -Wbad-function-cast warning.
3532 Use a different way to cause a compilation error if anyone uses
3533 n rather than nn, a way that does not involve shadowing.
3534 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
3536 * deps.mk (unexalpha.o): Remove; unused.
3538 New file unexec.h, the (simple) interface for unexec (Bug#8267).
3539 * unexec.h: New file.
3540 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
3541 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
3543 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
3544 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
3545 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.

3553 Rename locals to avoid shadowing.
3555 * lread.c (read1): Rewrite so as not to use empty "else".
3556 (Fload, readevalloop, read1): Rename locals to avoid shadowing.
3558 * print.c (Fredirect_debugging_output): Fix pointer signedess.
3560 * lisp.h (debug_output_compilation_hack): Add decl here, to avoid
3561 warning when compiling print.c.
3563 * font.c (font_unparse_fcname): Abort in an "impossible" situation
3564 instead of using an uninitialized var.
3565 (font_sort_entities): Mark var as initialized.

3601 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
3602 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
3603 some of which prompt warnings from gcc -Wbad-function-cast.

3616 gcc -Wbad-function-cast warning.
3617 (default_value, arithcompare, arith_driver, arith_error): Now static.

3624 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
3625 Rename locals to avoid shadowing.
3626 (mark_stack): Move local variables into the #ifdef region where
3628 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
3629 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
3631 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
3632 (GC_STRING_CHARS): Remove; not used.
3633 (Fmemory_limit): Cast sbrk's returned value to char *.
3635 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
3636 avoids undefined behavior in theory.
3638 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
3640 Use functions, not macros, for up- and down-casing (Bug#8254).
3641 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
3642 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
3643 to use the following functions instead of these macros.
3644 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
3645 EMACS_INT, since callers assume the returned value fits in int.
3646 (upcase1): Likewise, for UPCASE_TABLE.
3647 (uppercasep, lowercasep, upcase): New static inline functions.
3648 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

3653 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
3654 (regex_compile, re_search_2, re_match_2_internal):
3655 Remove unused local vars.
3656 (FREE_VAR): Rewrite so as not to use empty "else",
3657 which gcc can warn about.
3658 (regex_compile, re_match_2_internal): Mark locals as initialized.
3659 (RETALLOC_IF): Define only if needed.
3660 (WORDCHAR_P): Likewise. This one is never needed, but is used
3661 only in a comment talking about a compiler bug, so put inside
3662 the #if 0 of that comment.
3663 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
3664 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
3667 * search.c (boyer_moore): Rename locals to avoid shadowing.
3668 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
3669 (PREV_CHAR_BOUNDARY): Likewise.
3671 * search.c (simple_search): Remove unused var.
3673 * dired.c (compile_pattern): Move decl from here ...

3677 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
3679 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
3681 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
3682 Rename locals to avoid shadowing.
3683 (Fvertical_motion): Mark locals as initialized.
3685 * casefiddle.c (casify_object, casify_region): Now static.
3686 (casify_region): Mark local as initialized.
3688 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
3690 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
3691 New macros, so that the caller can use some names other than
3692 gcpro1, gcpro2, etc.
3693 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
3695 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
3696 argument, for consistency with GCPRO2_VAR, etc: it is now the
3697 prefix of the variable, not the variable itself. All uses
3699 * dired.c (directory_files_internal, file_name_completion):
3700 Rename locals to avoid shadowing.
3702 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
3703 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
3704 dired.c's scmp function, had undefined behavior.
3705 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
3706 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
3707 * buffer.h: ... to here, because these macros use current_buffer,
3708 and the new implementation with inline functions needs to have
3709 current_buffer in scope now, rather than later when the macros
3711 (downcase, upcase1): New static inline functions.
3712 (DOWNCASE, UPCASE1): Reimplement using these functions.
3713 This avoids undefined behavior in expressions like
3714 DOWNCASE (x) == DOWNCASE (y), which previously suffered
3715 from race conditions in accessing the global variables
3716 case_temp1 and case_temp2.
3717 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
3718 * lisp.h (case_temp1, case_temp2): Remove their decls.
3719 * character.h (ASCII_CHAR_P): Move from here ...
3720 * lisp.h: ... to here, so that the inline functions mentioned
3723 * dired.c (directory_files_internal_unwind): Now static.
3725 * fileio.c (file_name_as_directory, directory_file_name):
3726 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
3728 (file_name_as_directory): Use const pointers when appropriate.
