6 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
8 * emacs.c: Move the inclusion of TERM_HEADER after including

12 2012-10-01 Eli Zaretskii <eliz@gnu.org>
14 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
15 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
16 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
17 as the previous version used 'void *'.
19 * ralloc.c (ROUNDUP): Fix last change.
20 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
23 * w32proc.c <disable_itimers>: New static flag.
24 (init_timers): Initialize it to zero, after creating the critical
25 sections used by the timer threads.
26 (term_timers): Set to 1 before deleting the critical sections.
27 (getitimer, setitimer): If disable_itimers is non-zero, return an
28 error indication without doing anything. Reported by Fabrice
29 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
30 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
32 [!HAVE_SETITIMER]: Behave as the previous version that didn't

36 term_ntproc after all the other bookkeeping, to get timers working
39 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
41 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
42 Suggested by Juri Linkov in
43 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
45 Prefer plain 'static' to 'static inline' (Bug#12541).
46 With static functions, modern compilers inline pretty well by
47 themselves; advice from programmers often hurts as much as it helps.
48 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
49 this change shrinks the text size of the Emacs executable by 1.1%
50 without affecting CPU significantly in my benchmark.

133 Revert the FOLLOW-SYMLINKS change for file-attributes.
134 Doing it right would require several changes to Tramp, and there's
135 not enough time to get that tested before the freeze today.
136 * dired.c (directory_files_internal, Ffile_attributes):
139 * frame.c (x_report_frame_params): Port better to wider ints.
140 Do not assume that EMACS_UINT is the same width as uprintmax_t,

352 Prefer timer_settime if available, and prefer
353 thread cputime clocks, then process cputime clocks, then
354 monotonic clocks, to the old realtime clock. Use make_timeval
355 to round more-correctly when falling back to setitimer.
356 (Fprofiler_cpu_start): Use it.
357 (Fprofiler_cpu_stop): Prefer timer_settime if available.
358 Don't assume that passing NULL as the 2nd argument of setitimer

361 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
362 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in

365 in profiler.c, since sysdep.c now uses it.
367 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

422 * charset.c, charset.h (maybe_unify_char): Now static.
423 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
424 Since this stuff is now private to charset.c, there's no need for
425 a public macro and no need to inline by hand.

473 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
475 Move Vlibrary_cache to emacs.c and reset before dumping.
477 * lisp.h (reset_image_types): Declare.
478 [WINDOWSNT] (Vlibrary_cache): Declare.
480 * image.c (reset_image_types): New function.
482 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

493 * w32proc.c (sys_signal): Handle all signals defined by the
494 MS-Windows runtime, not just SIGCHLD. Actually install the signal
495 handlers for signals supported by Windows. Don't override
496 term_ntproc as the handler for SIGABRT.
497 (sigaction): Rewrite to call sys_signal instead of duplicating its
499 (sys_kill): Improve commentary.
501 * w32.c (term_ntproc): Accept (and ignore) one argument, for
502 consistency with a signature of a signal handler. All callers
504 (init_ntproc): Accept an argument DUMPING. If dumping, don't
505 install term_ntproc as a signal handler for SIGABRT, as that
506 should be done by the dumped Emacs.
508 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
510 * w32select.c (term_w32select): Protect against repeated
511 invocation by setting clipboard_owner to NULL after calling
514 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
515 and term_ntproc to their modified signatures.
517 * character.c (char_string, string_char): Remove calls to
518 MAYBE_UNIFY_CHAR. See the discussion starting at
519 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
522 2012-09-25 Chong Yidong <cyd@gnu.org>

529 when encountering an unknown bytecode.
531 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
533 image.c, indent.c: Use bool for booleans.
534 * dispextern.h (struct image_type): Members valid_p, load, init
535 now return bool, not int. All uses changed.
536 * image.c: Omit unnecessary static decls.
537 (x_create_bitmap_mask, x_build_heuristic_mask):
538 Return void, not int, since callers don't care about the return value.

573 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
575 Move pid_t related decls out of lisp.h.
576 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
577 (interruptible_wait_for_termination):
578 Move these decls from lisp.h to syswait.h, since they use pid_t.
579 Needed on FreeBSD; see Herbert J. Skuhra in
580 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.

601 Use bool for boolean.
602 * gtkutil.c (xg_update_frame_menubar):
603 * xmenu.c (update_frame_menubar):
604 Return void, not int, since caller ignores return value.

627 2012-09-23 Eli Zaretskii <eliz@gnu.org>
629 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
630 fatal_error_backtrace.
632 * w32proc.c (sys_kill): Undo last change: don't do anything when
633 invoked to deliver SIGABRT to our own process. This is now
634 handled by emacs_raise.
636 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
638 * w32term.c (w32_read_socket): Remove leftover reference to
639 interrupt_input_pending.
641 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
643 Do not use SA_NODEFER.
644 Problem reported by Dani Moncayo in
645 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
647 * sysdep.c (emacs_abort): Do not reset signal handler.
648 * emacs.c (terminate_due_to_signal): Reset signal handler here.
649 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
650 wanted even on POSIXish hosts, and it doesn't work on Windows.
652 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
654 * xterm.c (x_term_init): Call fixup_locale before and after calling
655 gtk_init (Bug#12392).
657 2012-09-23 Chong Yidong <cyd@gnu.org>
659 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
660 Vdynamic_library_alist.
662 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
663 (Fgnutls_available_p): Caller changed.
665 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
666 (Flibxml_parse_xml_region): Likewise.
668 * dispextern.h (struct image_type): Remove arg from init function.
670 * image.c (Finit_image_library, lookup_image_type)
671 (define_image_type): Remove now-unneeded second arg.
672 (init_xpm_functions, init_png_functions, init_jpeg_functions)
673 (init_tiff_functions, init_gif_functions, init_svg_functions):
674 Arglist and w32_delayed_load calling convention changed.
675 (gs_type): Remove init_gs_functions; there is no such function.
676 (valid_image_p, make_image): Fix caller to lookup_image_type.
678 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
680 Simplify and avoid signal-handling races (Bug#12471).
682 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
683 Avoid recursive loop if there's a fatal error in the function itself.
684 * atimer.c (pending_atimers):
685 * blockinput.h: Don't include "atimer.h"; no longer needed.
686 (interrupt_input_pending): Remove. All uses removed.
687 pending_signals now counts both atimers and ordinary interrupts.
688 This is less racy than having three separate pending-signal flags.
689 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
691 Rename from their upper-case counterparts BLOCK_INPUT,
692 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
693 INPUT_BLOCKED_P, and turn into functions. All uses changed.
694 This makes it easier to access volatile variables more accurately.
695 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
696 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
697 that's more reliable if the code is buggy and sets
698 interrupt_input_blocked to a negative value. All uses changed.
699 * atimer.c (deliver_alarm_signal):
700 Remove. No need to deliver this to the parent; any thread can
701 handle this signal now. All uses replaced by underlying handler.
702 * atimer.c (turn_on_atimers):
703 * dispnew.c (handle_window_change_signal):
704 * emacs.c (handle_danger_signal):
705 * keyboard.c (kbd_buffer_get_event):
706 Don't reestablish signal handler; not needed with sigaction.
707 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
709 Rework to avoid unnecessary accesses to volatile variables.
710 (UNBLOCK_INPUT_TO): Now a function.
711 (totally_unblock_input, unblock_input): New decls.
712 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
713 (init_data): Remove. Necessary stuff now done in init_signal.
714 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
715 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
716 (fatal_error_code): Remove; no longer needed.
717 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
718 it doesn't always backtrace. All uses changed. No need to reset
719 signal to default, since sigaction and/or die does that for us now.
720 Use emacs_raise (FOO), not kill (getpid (), FOO).
721 (main): Check more-accurately whether we're dumping.
722 Move fatal-error setup to sysdep.c
723 * floatfns.c: Do not include "syssignal.h"; no longer needed.
724 * gtkutil.c (xg_get_file_name, xg_get_font):
725 Remove no-longer-needed signal-mask manipulation.
726 * keyboard.c, process.c (POLL_FOR_INPUT):
727 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
728 * keyboard.c (read_avail_input): Remove.
729 All uses replaced by gobble_input.
730 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
731 (kbd_buffer_store_event_hold, gobble_input):
732 (record_asynch_buffer_change) [USABLE_SIGIO]:
733 (store_user_signal_events):
734 No need to mess with signal mask.
735 (gobble_input): If blocking input and there are terminals, simply
736 set pending_signals to 1 and return. All hooks changed to not
737 worry about whether input is blocked.
738 (process_pending_signals): Clear pending_signals before processing
739 them, in case a signal comes in while we're processing.
740 By convention callers now test pending_signals before calling us.
741 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
742 New functions, to support changes to blockinput.h.
743 (handle_input_available_signal): Now extern.
744 (reinvoke_input_signal): Remove. All uses replaced by
746 (quit_count): Now volatile, since a signal handler uses it.
747 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
748 All callers changed. Block SIGINT only if not already blocked.
749 Clear sigmask reliably, even if Fsignal returns, which it can.
750 Omit unnecessary accesses to volatile var.
751 (quit_throw_to_read_char): No need to restore sigmask.
752 * keyboard.c (gobble_input, handle_user_signal):
753 * process.c (wait_reading_process_output):
754 Call signal-handling code rather than killing ourselves.
755 * lisp.h: Include <float.h>, for...
756 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
757 (pending_signals): Now volatile.
758 (syms_of_data): Now const if IEEE floating point.
759 (handle_input_available_signal) [USABLE_SIGIO]:
760 (terminate_due_to_signal, record_child_status_change): New decls.
761 * process.c (create_process): Avoid disaster if memory is exhausted
762 while we're processing a vfork, by tightening the critical section
764 (send_process_frame, process_sent_to, handle_pipe_signal)
765 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
767 (send_process): No need for setjmp/longjmp any more, since the
768 SIGPIPE stuff is now gone. Instead, report an error if errno
770 (record_child_status_change): Now extern. PID and W are now args.
771 Return void, not bool. All callers changed.
772 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
773 Remove. All uses removed. This bug should be fixed now in a
775 (wait_for_termination_1): Use waitpid rather than sigsuspend,
776 and record the child status change directly. This avoids the
777 need to futz with the signal mask.
778 (process_fatal_action): Move here from emacs.c.
779 (emacs_sigaction_flags): New function, containing
780 much of what used to be in emacs_sigaction_init.
781 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
782 caught by emacs, to make races less likely.
783 (deliver_process_signal): Rename from handle_on_main_thread.
785 (BACKTRACE_LIMIT_MAX): Now at top level.
786 (thread_backtrace_buffer, threadback_backtrace_pointers):
788 (deliver_thread_signal, deliver_fatal_thread_signal):
789 New functions, for more-accurate delivery of thread-specific signals.
790 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
791 (deliver_arith_signal): Handle in this thread, not
792 in the main thread, since it's triggered by this thread.
793 (maybe_fatal_sig): New function.
794 (init_signals): New arg DUMPING so that we can be more accurate
795 about whether we're dumping. Caller changed.
796 Treat thread-specific signals differently from process-general signals.
797 Block all signals while handling fatal error; that's safer.
798 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
800 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
801 Ignore SIGPIPE unless batch.
802 (emacs_backtrace): Output backtrace for the appropriate thread,
803 which is not necessarily the main thread.
804 * syssignal.h: Include <stdbool.h>.
805 (emacs_raise): New macro.
806 * xterm.c (x_connection_signal): Remove; no longer needed
807 now that we use sigaction.
808 (x_connection_closed): No need to mess with sigmask now.
809 (x_initialize): No need to reset SIGPIPE handler here, since
810 init_signals does this for us now.
812 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
814 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
815 background rect may be larger (Bug#12245).
817 2012-09-23 Chong Yidong <cyd@gnu.org>
819 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
821 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
823 * .gdbinit: Just stop at fatal_error_backtrace.
824 See Stefan Monnier's request in
825 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
826 Remove no-longer-used query of system type.
828 2012-09-22 Chong Yidong <cyd@gnu.org>
830 * search.c (Freplace_match): Doc fix (Bug#12325).
832 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).

841 * dispextern.h (struct image_type): Add new slot, storing a type
842 initialization function.
844 * image.c (define_image_type): Call the image initializer function
845 if it is defined. Arguments and return value changed.
846 (valid_image_p, make_image): Callers changed.
847 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
848 (gif_type, imagemagick_type, svg_type, gs_type):
849 Add initialization functions.
850 (Finit_image_library): Call lookup_image_type.
851 (CHECK_LIB_AVAILABLE): Macro deleted.
852 (lookup_image_type): Call define_image_type here, rather than via
853 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
854 (syms_of_image): Move define_image_type calls for xbm_type and
855 pbm_type to lookup_image_type.
857 2012-09-22 Eli Zaretskii <eliz@gnu.org>
859 * keyboard.c (timer_check_2): Move calculation of 'timers' and
860 'idle_timers' from here ...
861 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
862 lists, to avoid infloops when the timer does something stupid,
863 like reinvoke itself with the same or smaller time-out.
866 2012-09-22 Martin Rudalics <rudalics@gmx.at>
868 * window.c (Fsplit_window_internal): Handle only Qt value of
869 Vwindow_combination_limit separately.

874 2012-09-22 Eli Zaretskii <eliz@gnu.org>
876 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
877 the new overlay string. (Bug#10159)
879 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
881 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
882 or that fprintf is async-signal-safe. POSIX doesn't require
885 2012-09-22 Chong Yidong <cyd@gnu.org>
887 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
890 2012-09-22 Kenichi Handa <handa@gnu.org>
892 * composite.c (composition_reseat_it): Handle the case that a
893 grapheme cluster is not covered by a single font (Bug#12352).
895 2012-09-21 Chong Yidong <cyd@gnu.org>
897 * image.c (define_image_type): Avoid adding duplicate types to
898 image_types (Bug#12463). Suggested by Jörg Walter.
900 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
902 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
903 (print_load_command_name): Add case LC_DATA_IN_CODE.
904 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
906 2012-09-21 Glenn Morris <rgm@gnu.org>

909 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
911 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
913 * fileio.c (Ffile_selinux_context): Only call freecon when
914 lgetfilecon succeeded.
915 (Fset_file_selinux_context): Likewise. (Bug#12444)
917 2012-09-21 Eli Zaretskii <eliz@gnu.org>
919 * xdisp.c (try_window_reusing_current_matrix): Under bidi
920 reordering, locate the cursor by calling set_cursor_from_row; if
921 that fails, clear the desired glyph matrix before returning a
922 failure indication to the caller. Fixes leaving garbled display
923 when fast scrolling with a down-key. (Bug#12403)
924 (compute_stop_pos_backwards): Fix a typo that caused crashes while
925 scrolling through multibyte text.
927 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
929 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
930 calling mark_vectorlike since that's the one that marks the window.
931 (mark_discard_killed_buffers): Mark the final cdr.
932 * window.h (struct window): Move prev/next_buffers to the
934 * window.c (make_window): Initialize prev/next_buffers manually.
936 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
938 Omit unused arg EXPECTED from socket hooks.
939 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
940 * nsterm.m (ns_term_init):
941 * termhooks.h (struct terminal.read_socket_hook):
942 * w32inevt.c (w32_console_read_socket):
943 * w32term.c (w32_read_socket):
944 * xterm.c (XTread_socket):
945 Omit unused arg EXPECTED. All callers changed.
946 (store_user_signal_events): Return void, not int, since callers no
947 longer care about the return value. All uses changed.
949 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
951 * w32gui.h (XParseGeometry): Do not declare.
953 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
955 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
956 Ignore 'expected'. See Eli Zaretskii in
957 <http://bugs.gnu.org/12471#8> (last line).
959 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
960 (XParseGeometry): Now static. Substitute extremal values for
961 values that are out of range.
963 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
965 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
967 * nsfns.m (XParseGeometry): Remove.
968 (Fx_create_frame): Call x_set_offset to correctly interpret
971 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
972 (Fx_parse_geometry): If there is a space in string, call
973 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
975 2012-09-17 Eli Zaretskii <eliz@gnu.org>
977 * search.c (scan_buffer): Use character positions in calls to
978 region_cache_forward and region_cache_backward, not byte
979 positions. (Bug#12196)
981 * w32term.c (w32_read_socket): Set pending_signals to 1, like
982 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
984 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
985 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
986 emacs_blocked_malloc, now deleted.
988 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
990 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
991 The workaround was for improving performance on Solaris 2.4, but
992 is getting in the way now. Emacs will still work if someone is
993 still running Solaris 2.4 in a museum somewhere; Sun dropped
994 support for Solaris 2.4 in 2003.
995 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
996 * process.c (create_process) [HAVE_WORKING_VFORK]:
997 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
998 since Emacs no longer uses vfork on that platform.
1000 2012-09-17 Glenn Morris <rgm@gnu.org>
1002 * emacs.c: Use COPYRIGHT.
1004 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
1006 Remove configure's --without-sync-input option (Bug#12450).
1007 When auditing signal-handling in preparation for cleaning it up,
1008 I found that SYNC_INPUT has race conditions and would be a real
1009 pain to fix. Since it's an undocumented and deprecated
1010 configure-time option, now seems like a good time to remove it.
1011 Also see <http://bugs.gnu.org/11080#16>.
1012 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
1013 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
1014 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
1015 (malloc_hysteresis):
1016 (check_depth) [XMALLOC_OVERRUN_CHECK]:
1017 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
1018 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
1019 (dont_register_blocks, bytes_used_when_reconsidered)
1020 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
1021 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
1022 [!SYSTEM_MALLOC && !SYNC_INPUT]:
1023 Remove. All uses removed.
1024 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
1025 implementation, one that depends on whether the new macro
1026 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
1028 * atimer.c (run_timers, handle_alarm_signal):
1029 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
1030 (handle_async_input, process_pending_signals)
1031 (handle_input_available_signal, init_keyboard):
1032 * nsterm.m (ns_read_socket):
1033 * process.c (wait_reading_process_output):
1034 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
1035 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
1037 * xterm.c (XTread_socket):
1039 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
1040 * eval.c (handling_signal): Remove. All uses removed.
1041 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
1042 All uses replaced with the SYNC_INPUT version.
1043 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
1045 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1048 * font.c (Ffont_shape_gstring): Remove unused local.
1050 2012-09-16 Glenn Morris <rgm@gnu.org>
1052 * Makefile.in (clean): No longer run nextstep's clean.
1054 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
1056 (ns-app): Move here from ns.mk, and simplify.
1057 (clean): Simplify nextstep entry.
1058 * ns.mk: Remove file.
1060 2012-09-17 Kenichi Handa <handa@gnu.org>
1062 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
1063 not covert the last few charactes.
1065 2012-09-16 Kenichi Handa <handa@gnu.org>
1067 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
1068 here, but just check the validity of glyphs in the glyph-string.
1070 2012-09-16 Martin Rudalics <rudalics@gmx.at>
1072 * window.c (Fwindow_parameter, Fset_window_parameter):
1073 Accept any window as argument (Bug#12452).
1075 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
1077 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
1078 to ns_term_init to avoid memory leak.
1080 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
1081 explicit retain/release.
1082 (ns_term_init): Only allow one display. Initialize outerpool and
1085 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1087 Port _setjmp fix to POSIXish hosts as well as Microsoft.
1088 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
1089 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
1090 the Microsoft problem in a different way, by altering ../nt/config.nt.
1092 2012-09-15 Eli Zaretskii <eliz@gnu.org>
1107 * w16select.c: Remove inclusion of setjmp.h, as it is now included
1108 by lisp.h. This completes removal of setjmp.h inclusion
1109 erroneously announced in the previous commit. (Bug#12446)
1111 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
1114 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
1115 not defined as a macro. The latter happens on MS-Windows.
1118 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1120 Port better to POSIX hosts lacking _setjmp (Bug#12446).
1121 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
1122 Some instances of '#include <setjmp.h>' removed, if the
1123 only reason for the instance was because "lisp.h" was included.
1124 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
1125 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
1126 and _longjmp with the new symbols. Emacs already uses _setjmp if
1127 available, so this change affects only POSIXish hosts that have
1128 sigsetjmp but not _setjmp, such as some versions of Solaris and
1129 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
1130 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
1131 (png_load_body) [HAVE_PNG]:
1132 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
1133 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
1134 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
1135 since PNG requires jmp_buf. This is the only exception to the
1136 general rule that we now use sys_setjmp and sys_longjmp.
1137 This exception is OK since this code does not change the signal
1138 mask or longjmp out of a signal handler.
1140 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
1142 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
1143 Include "syssignal.h", for 'main_thread'.
1145 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
1147 Avoid out-of-range marker position (Bug#12426).
1148 * insdel.c (replace_range, replace_range_2):
1149 Adjust markers before overlays, as suggested by comments.
1150 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
1151 Remove redundant check before calling offset_intervals.
1153 2012-09-14 Martin Rudalics <rudalics@gmx.at>
1155 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
1156 current buffer (Bug#12387).
1158 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
1160 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
1162 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
1164 Use a more backwards-compatible timer format (Bug#12430).
1165 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
1166 vector element, not from the 4th, since PSECS is now at the end.
1167 (Fcurrent_idle_time): Doc fix.
1169 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
1171 Function to mark objects and remove killed buffers at once.
1172 * alloc.c (discard_killed_buffers): Rename to ...
1173 (mark_discard_killed buffers) ... new name. Add marking
1174 of remaining objects. Fix comment. Adjust users.
1175 (mark_object): Do not touch frame buffer lists here.
1176 * frame.c (delete_frame): Reset frame buffer lists here.
1178 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
1180 Better workaround for GNOME bug when --enable-gcc-warnings.
1181 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
1182 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
1183 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
1185 Simplify SIGIO usage (Bug#12408).
1186 The code that dealt with SIGIO was crufty and confusing, e.g., it
1187 played tricks like "#undef SIGIO" but these tricks were not used
1188 consistently. Simplify mostly by not #undeffing standard symbols,
1189 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
1190 or not as we please) rather than "defined SIGIO" (standard symbol
1191 that we probably shouldn't #undef).
1192 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
1193 Modules that need it can include it.
1194 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
1195 * dispextern.h (ignore_sigio): New decl.
1196 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
1197 unconditionally, since it's now a no-op if !USABLE_SIGIO.
1198 * emacs.c (shut_down_emacs):
1199 * keyboard.c (kbd_buffer_store_event_hold):
1200 Use ignore_sigio rather than invoking 'signal' directly.
1201 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
1203 (FIONREAD, SIGIO): Do not #undef.
1204 (tty_read_avail_input): Use #error rather than a syntax error.
1205 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
1206 for I_PIPE, used by SETUP_SLAVE_PTY.
1207 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
1208 * sysdep.c (croak): Remove; no longer needed. This bit of
1209 temporary code, with Fred N. Fish's comment that it's temporary,
1210 has been in Emacs since at least 1992!
1211 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
1212 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
1213 * syssignal.h (croak): Remove decl.
1214 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
1215 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
1216 now that we're termios-only.
1217 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
1218 * term.c (dissociate_if_controlling_tty): Use #error rather than
1221 Work around GCC and GNOME bugs when --enable-gcc-warnings.
1222 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
1223 to work around GNOME bug 683906.
1224 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
1225 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
1226 This works around GCC bug 54561.
1228 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
1230 More fixes for 'volatile' and setjmp/longjmp.
1231 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
1232 * image.c (struct png_load_context) [HAVE_PNG]: New type.
1233 (png_load_body) [HAVE_PNG]:
1234 (jpeg_load_body) [HAVE_JPEG]:
1235 New function, with most of the old parent function's body.
1236 (png_load) [HAVE_PNG]:
1237 (jpeg_load) [HAVE_JPEG]:
1238 Invoke the new function, to avoid longjmp munging our locals.
1239 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
1240 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
1241 longjmp is passed 2, as the C standard doesn't guarantee this.
1242 Instead, store the failure code into mgr->failure_code.
1244 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
1246 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
1247 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
1248 (syms_of_keyboard): Remove support for unread-command-char.
1250 2012-09-12 Eli Zaretskii <eliz@gnu.org>
1252 * w32proc.c (sys_kill): If PID is our process ID and the signal is
1253 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
1254 violation. (Bug#12426)
1256 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
1258 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
1260 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
1262 * eval.c: Add `inhibit-debugger'.
1263 (Qinhibit_debugger): New symbol.
1264 (call_debugger): Bind it instead of Qdebug_on_error.
1265 (maybe_call_debugger): Test Vinhibit_debugger.
1266 (syms_of_eval): Define inhibit-debugger.
1267 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
1268 (syms_of_xdisp): Remove inhibit-debug-on-message.
1270 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
1272 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
1273 If a nonvolatile local variable is written before a _longjmp to
1274 the frame containing the variable, and is read after the _longjmp,
1275 the value read is indeterminate. Some local variables of type
1276 'struct handler' and 'struct catchtag' are used in this way, so
1277 mark each of their slots as volatile if the slot can be set before
1278 _longjmp and read afterwards.
1279 * lisp.h (struct handler): var and chosen_clause are now volatile.
1280 (struct catchtag): val, next, and pdlcount are now volatile.
1282 * bidi.c (bidi_push_it, bidi_pop_it):
1283 * fns.c (copy_hash_table):
1284 * image.c (define_image_type):
1285 * keyboard.c (kbd_buffer_store_event_hold):
1286 * process.c (Fprocess_send_eof):
1287 * xfaces.c (x_create_gc) [HAVE_NS]:
1288 * xgselect.c (xg_select):
1289 Prefer assignment to memcpy when either will do.
1291 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
1292 Use pointer-to-a-pointer to simplify and avoid a NILP check each
1293 time an item is removed. No need to mark this function 'inline';
1294 the compiler knows better than we do.
1296 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
1298 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
1299 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
1300 to change_frame_size (Bug#12388).
1301 (windowDidResize:): Pass YES to updateFrameSize.
1303 * nsterm.h: Add delay parameter to updateFrameSize.
1305 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
1307 Discard killed buffers from deleted window and frame objects.
1308 This reduces an amount of references to killed buffers and
1309 helps GC to reclaim them faster.
1310 * alloc.c (discard_killed_buffers): New function.
1311 (mark_object): Use it for deleted windows and frames.
1312 (mark_object): If symbol's value is set up for a killed buffer
1313 or deleted frame, restore it's global binding.
1314 * data.c (swap_in_global_binding): Add GC notice.
1315 (swap_in_symval_forwarding): Use convenient set_blv_where.
1316 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
1317 * window.h: ... to here.
1319 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
1321 Convenient macro to check whether the buffer is live.
1322 * buffer.h (BUFFER_LIVE_P): New macro.
1323 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
1324 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
1326 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1328 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
1329 composition cases (Bug#12364).
1331 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
1332 overhang of succeeding glyphs overlapping box cursor.
1334 * w32term.c (x_draw_glyph_string): Likewise.
1336 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
1338 Simplify, document, and port floating-point (Bug#12381).
1339 The porting part of this patch fixes bugs on non-IEEE platforms
1340 with frexp, ldexp, logb.
1341 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
1343 * floatfns.c: Simplify discussion of functions that Emacs doesn't
1344 support, by removing commented-out code and briefly listing the
1345 C89 functions excluded. The commented-out stuff was confusing
1346 maintenance, e.g., we thought we needed cbrt but it was commented out.
1347 (logb): Remove decl; no longer needed.
1348 (isfinite): New macro, if not already supplied.
1349 (isnan): Don't replace any existing macro.
1350 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
1351 are present on all C89 platforms.
1352 (Ffrexp): Do not special-case zero, as frexp does the right thing
1354 (Flogb): Do not use logb, as it doesn't have the desired meaning
1355 on hosts that use non-base-2 floating point. Instead, stick with
1356 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
1357 frexp, to avoid getting an unspecified result.
1359 * xdisp.c (Qinhibit_debug_on_message): Now static.
1361 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
1363 * nsterm.m (ns_update_begin): Set clip path to whole view by using
1364 NSBezierPath (Bug#12131).
1366 2012-09-10 Chong Yidong <cyd@gnu.org>
1368 * fns.c (Fdelq, Fdelete): Doc fix.
1370 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
1372 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
1373 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
1375 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
1377 * lisp.h (make_lisp_ptr): New macro to replace XSET.
1378 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
1381 2012-09-09 Eli Zaretskii <eliz@gnu.org>
1383 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
1384 left fringe if the window has a left margin. This avoids leaving
1385 traces of the cursor because its leftmost pixel is not drawn over.
1387 * dispnew.c (update_window_line): When the left margin area of a
1388 screen line is updated, set the redraw_fringe_bitmaps_p flag of
1389 that screen line. (Bug#12277)
1391 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
1393 Assume C89 or later for math functions (Bug#12381).
1394 This simplifies the code, and makes it a bit smaller and faster,
1395 and (most important) makes it easier to clean up signal handling
1396 since we can stop worring about floating-point exceptions in
1397 library code. That was a problem before C89, but the problem
1398 went away many years ago on all practical Emacs targets.
1399 * data.c, image.c, lread.c, print.c:
1400 Don't include <math.h>; no longer needed.
1401 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
1402 might be autoconfigured, as that never happens.
1404 * doprnt.c (DBL_MAX_10_EXP):
1405 * print.c (DBL_DIG):
1406 Remove. C89 or later always defines these.
1407 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
1408 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
1409 (arith_error, domain_error, domain_error2):
1410 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
1411 no longer needed -- we simply return what C returns. All uses removed.
1412 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
1414 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
1415 Remove. All uses expanded, as these macros are no longer used
1416 more than once and are now more trouble than they're worth.
1417 (Ftan): Use tan, not sin / cos.
1418 (Flogb): Assume C89 frexp.
1419 (fmod_float): Assume C89 fmod.
1420 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
1421 (init_floatfns): Remove. All uses removed.
1423 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1425 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
1426 compositeToPoint for OSX < 10.6 (Bug#12390).
1428 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
1430 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
1431 This produces more-accurate results.
1433 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1435 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
1436 changes (Bug#12088).
1438 2012-09-08 Chong Yidong <cyd@gnu.org>
1440 * syntax.c (Fstring_to_syntax): Doc fix.
1442 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1444 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
1445 in the internal border.
1446 (x_set_window_size): Remove static variables and their usage.
1447 (ns_redraw_scroll_bars): Fix NSTRACE arg.
1448 (ns_after_update_window_line, ns_draw_fringe_bitmap):
1449 Remove fringe/internal border adjustment (Bug#11052).
1450 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
1451 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
1452 (ns_fix_rect_ibw): Remove.
1453 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
1454 (ns_dumpglyphs_box_or_relief): Ditto.
1455 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
1457 (ns_dumpglyphs_image): Ditto.
1458 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
1460 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
1461 their usage. Add fringe_extended_p and its use as in other terms.
1462 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
1463 scroll bar was removed.
1464 (updateFrameSize): New function.
1465 (windowDidResize): Move code to updateFrameSize and call it.
1467 * nsterm.h (EmacsView): Add updateFrameSize.
1469 2012-09-07 Chong Yidong <cyd@gnu.org>
1471 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
1473 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
1475 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1477 More signal-handler cleanup (Bug#12327).
1478 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
1479 Problem introduced when merging patches. Noted by Eli Zaretskii in
1480 <http://bugs.gnu.org/12327#67>.
1481 * floatfns.c: Comment fix.
1482 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
1483 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
1484 and anyway the declaration is harmless even if SIGDANGER is not defined.
1485 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
1486 defined BROKEN_FIONREAD). systty.h formerly did this, but other
1487 source files not surprisingly expected syssignal.h to define, or
1488 not define, SIGIO, and it's cleaner to do it that way, for consistency.
1489 Include <sys/ioctl.h>, for FIONREAD.
1490 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
1491 This eliminates a problem whereby other files mysteriously had
1492 to include "syssignal.h" before including "systty.h" if they
1493 wanted to use "#ifdef SIGIO".
1495 2012-09-07 Eli Zaretskii <eliz@gnu.org>
1497 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
1499 * w32.c (sigemptyset): Empty the set.
1500 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
1502 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
1504 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
1506 * alloc.c (mark_buffer): Revert unsafe marking optimization.
1507 (mark_object): Likewise for frame objects.
1509 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1511 * syssignal.h (handle_on_main_thread): Always declare,
1512 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
1513 This ports to platforms without HAVE_PTHREAD.
1515 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1517 Signal-handler cleanup (Bug#12327).
1518 Emacs's signal handlers were written in the old 4.2BSD style with
1519 sigblock and sigmask and so forth, and this led to some
1520 inefficiencies and confusion. Rewrite these to use
1521 pthread_sigmask etc. without copying signal sets around. Also,
1522 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
1523 'signal', and instead use functions that do not attempt to take
1524 over the system name space. This patch causes Emacs's text
1525 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
1526 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
1527 Do not include <signal.h> or "syssignal.h", as these
1528 modules do not use signals.
1529 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
1530 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
1531 Do not include <signal.h>, as "syssignal.h" does that for us now.
1532 * atimer.c (sigmask_atimers): New function.
1533 (block_atimers, unblock_atimers): New functions,
1534 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
1536 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
1537 no longer needed here.
1538 * emacs.c (main): Inspect existing signal handler with sigaction,
1539 so that there's no need to block and unblock SIGHUP.
1540 * sysdep.c (struct save_signal): New member 'action', replacing
1541 old member 'handler'.
1542 (save_signal_handlers, restore_signal_handlers):
1543 Use sigaction instead of 'signal' to save and restore.
1544 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
1545 New function. All users of 'signal' modified to use set_sighandler
1546 if they're writeonly, and to use sys_signal if they're read+write.
1547 (emacs_sigaction_init, forwarded_signal): New functions.
1548 (sys_signal): Remove. All uses replaced by calls to sigaction
1549 and emacs_sigaction_init, or by direct calls to 'signal'.
1550 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
1551 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
1552 all uses replaced by pthread_sigmask etc. calls.
1553 * syssignal.h: Include <signal.h>.
1554 (emacs_sigaction_init, forwarded_signal): New decls.
1555 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
1556 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
1557 (sigmask, sys_sigmask): Remove; no longer needed.
1558 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
1559 (sigblock, sigunblock, sigfree):
1560 (sigsetmask) [!defined sigsetmask]:
1561 Remove. All uses replaced by pthread_sigmask.
1562 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
1563 no longer need to be replaced, and its typical old uses
1564 are now done via emacs_sigaction_init and sigaction.
1565 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
1566 (sys_sigdel): Remove; unused.
1567 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
1569 2012-09-06 Eli Zaretskii <eliz@gnu.org>
1571 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
1572 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
1574 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1576 Explicitly mark buffer_defaults and buffer_local_symbols.
1577 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
1578 mark_local_symbols here.
1579 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
1580 since special buffers aren't marked here any more.
1581 (allocate_buffer): Chain new buffer with all_buffers here...
1582 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
1584 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
1585 (syms_of_buffer): Remove staticpro of the above.
1586 (init_buffer_once): Set names for buffer_defaults and
1587 buffer_local_symbols.
1589 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1591 Use bool for booleans in font-related modules.
1592 * font.c (font_intern_prop, font_style_to_value)
1593 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
1594 (generate_otf_features, font_check_otf_features, font_check_otf)
1595 (font_match_p, font_list_entities, font_at):
1596 * fontset.c (fontset_id_valid_p, reorder_font_vector
1597 (fontset_find_font, Fset_fontset_font)
1598 (face_suitable_for_char_p) [0]:
1599 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
1600 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
1601 (m17n_flt_initialized, ftfont_shape_by_flt):
1602 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
1603 * nsfont.m (nsfont_draw):
1604 * w32font.c (w32font_draw):
1605 * w32term.c (x_draw_glyphless_glyph_string_foreground):
1606 Use bool for booleans.
1607 * font.h: Adjust to above API changes.
1608 (struct font, struct font_driver, struct font_driver_list):
1609 Use bool for booleans.
1610 (struct font): Remove useless member encoding_type.
1612 * fontset.c, xftfont.c: Omit unnecessary static decls.
1614 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1616 * alloc.c (mark_object): Revert window marking code
1617 since it's unsafe for the Fset_window_configuration.
1619 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1621 Fix race conditions with signal handlers and errno (Bug#12327).
1622 Be more systematic about preserving errno whenever a signal
1623 handler returns, even if it's not in the main thread. Do this by
1624 renaming signal handlers to distinguish between signal delivery
1625 and signal handling. All uses changed.
1626 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
1627 * data.c (deliver_arith_signal): Rename from arith_error.
1628 * dispnew.c (deliver_window_change_signal): Rename from
1629 window_change_signal.
1630 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
1631 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
1632 * keyboard.c (deliver_input_available_signal): Rename from
1633 input_available_signal.
1634 (deliver_user_signal): Rename from handle_user_signal.
1635 (deliver_interrupt_signal): Rename from interrupt_signal.
1636 * process.c (deliver_pipe_signal): Rename from send_process_trap.
1637 (deliver_child_signal): Rename from sigchld_handler.
1638 * atimer.c (handle_alarm_signal):
1639 * data.c (handle_arith_signal):
1640 * dispnew.c (handle_window_change_signal):
1641 * emacs.c (handle_fatal_signal, handle_danger_signal):
1642 * keyboard.c (handle_input_available_signal):
1643 * keyboard.c (handle_user_signal, handle_interrupt_signal):
1644 * process.c (handle_pipe_signal, handle_child_signal):
1645 New functions, with the actual signal-handling code taken from the
1646 original respective signal handlers, sans the sporadic attempts to
1647 preserve errno, since that's now done by handle_on_main_thread.
1648 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
1649 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
1650 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1652 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1653 Move initialization of main_thread to sysdep.c's init_signals.
1654 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
1655 our usage, and simplifies the mainline code.
1656 (record_child_status_change): New static function, as a helper
1657 for handle_child_signal, and with most of the old child handler's
1659 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
1660 (handle_child_signal): Use the above.
1661 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1662 Moved here from emacs.c.
1663 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
1664 code moved here from emacs.c's main function.
1665 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
1666 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
1667 This lets callers save and restore errno properly.
1669 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1671 Remove redundant or unused things here and there.
1672 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
1673 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
1674 * editfns.c (Fcompare_buffer_substrings): Likewise.
1675 * frame.h (struct terminal, struct font_driver_list):
1676 Remove redundant declarations.
1677 * window.h (Qleft, Qright): Likewise.
1679 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1681 Do not mark objects from deleted buffers, windows and frames.
1682 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
1683 (mark_object): Likewise for windows and frames.
1685 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1687 * alloc.c (valid_lisp_object_p): Treat killed buffers,
1688 buffer_defaults and buffer_local_symbols as valid objects.
1689 Return special value to denote them.
1691 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1693 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
1694 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
1695 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
1696 (file_name_absolute_p, Fsubstitute_in_file_name):
1697 (check_executable, check_writable, Ffile_accessible_directory_p)
1698 (Fset_file_selinux_context, Fdefault_file_modes)
1699 (Finsert_file_contents, choose_write_coding_system)
1700 (Fwrite_region, build_annotations, a_write, e_write)
1702 * filelock.c (boot_time_initialized, get_boot_time)
1703 (get_boot_time_1, lock_file_1, within_one_second):
1704 * floatfns.c (in_float):
1705 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
1706 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
1707 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
1708 * lisp.h (struct Lisp_Hash_Table.cmpfn):
1709 * window.c (compare_window_configurations):
1710 Use bool for booleans.
1711 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
1712 (Fdefault_file_modes): Now mode_t, not int, for modes.
1713 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
1714 (internal_delete_file): Now returns void, not a (boolean) int,
1715 since nobody was looking at the return value.
1716 * lisp.h, window.h: Adjust to above API changes.
1718 * xdisp.c (set_message): Simplify and reindent last change.
1720 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
1722 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
1724 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
1726 * eval.c (call_debugger): Make the function non-static so that we
1727 can call it from set_message.
1729 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
1730 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
1732 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1734 Give more-useful info on a fatal error (Bug#12328).
1735 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
1736 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
1737 of doing the work ourselves.
1738 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
1739 do most of the work.
1740 (fatal_error_backtrace): New function, taken from the guts
1741 of the old fatal_error_signal, but with a new option to output
1743 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
1744 info about the signal than just its number.
1745 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
1746 * sysdep.c: Include <execinfo.h>
1747 (emacs_backtrace): New function, taken partly from the previous
1748 code of the 'die' function.
1749 (emacs_abort): Call fatal_error_backtrace rather than abort.
1751 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
1753 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
1754 eager (load-time) macro-expansion.
1755 * lisp.mk (lisp): Add macroexp.
1757 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1759 Simplify redefinition of 'abort' (Bug#12316).
1760 Do not try to redefine the 'abort' function. Instead, redo
1761 the code so that it calls 'emacs_abort' rather than 'abort'.
1762 This removes the need for the NO_ABORT configure-time macro
1763 and makes it easier to change the abort code to do a backtrace.
1764 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
1765 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
1766 Remove; sysdep.c's emacs_abort now takes its place.
1767 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
1768 'abort' changed to use 'emacs_abort'.
1769 * msdos.c (dos_abort) [defined abort]: Remove; not used.
1770 (abort) [!defined abort]: Rename to ...
1771 (emacs_abort): ... new name.
1772 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
1773 the place of the old 'abort' in emacs.c.
1774 * w32.c, w32fns.c (abort): Do not #undef.
1775 * w32.c (emacs_abort): Rename from w32_abort.
1777 2012-09-04 Eli Zaretskii <eliz@gnu.org>
1779 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
1780 offsets[j].dv, since the y axis of the screen coordinates points
1781 down, while the y axis of the font definition coordinates points
1782 up. This fixes display of Arabic diacritics such as KASRA and
1783 KASRATAN. (Bug#11860)
1785 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1787 Be more systematic about _setjmp vs setjmp.
1788 * alloc.c (test_setjmp, mark_stack):
1789 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
1790 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
1791 (png_load, my_error_exit, jpeg_load):
1792 * process.c (send_process_trap, send_process):
1793 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
1794 The underscored versions are up to 30x faster on some hosts.
1795 Formerly, the code used setjmp+longjmp sometimes and
1796 _setjmp+_longjmp at other times, with no particular reason to
1797 prefer setjmp+longjmp.

1931 offset adjustment values separately for each cluster. (Bug#11860)
1933 * image.c: Restore mistakenly removed inclusion of w32.h. Without
1934 it, GCC doesn't see prototypes of w32_delayed_load, and complains
1935 about implicit conversions from integer to pointer.
1937 2012-09-01 Daniel Colascione <dancol@dancol.org>
1939 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

1993 window system declarations.
1995 * frame.h: Move common functions here: set_frame_menubar,
1996 x_set_window_size, x_sync, x_get_focus_frame,

2245 2012-08-27 Martin Rudalics <rudalics@gmx.at>
2247 * window.c (Fset_window_configuration): Record any window's old
2248 buffer if it's replaced (see Bug#8789). If the new current
2249 buffer doesn't appear in the selected window, go to its old
2252 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
2254 Special MEM_TYPE_SPARE to denote reserved memory.
2255 * alloc.c (enum mem_type): New memory type.
2256 (refill_memory_reserve): Use new type for spare memory.
2257 This prevents live_cons_p and live_string_p from incorrect
2258 detection of uninitialized objects from spare memory as live.
2260 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
2263 * Makefile.in (.PHONY): versioclean -> versionclean.
2265 Remove unused external symbols.
2266 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
2267 * window.c (Qwindow_valid_p, decode_valid_window):
2268 Now static, not extern.
2269 * data.c (Qinterval): Remove; unused.
2270 (syms_of_data): Do not define 'interval'.
2271 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
2272 * window.h (decode_valid_window):
2275 * character.c, charset.c, chartab.c: Use bool for booleans.
2276 * character.c (lisp_string_width, string_count_byte8)
2277 (string_escape_byte8):
2278 * charset.c (charset_map_loaded, load_charset_map, read_hex):
2279 (load_charset_map_from_file, map_charset_chars)
2280 (Fdefine_charset_internal, define_charset_internal)
2281 (Fdeclare_equiv_charset, find_charsets_in_text)
2282 (Ffind_charset_region, char_charset, Fiso_charset):
2283 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
2284 (sub_char_table_set, sub_char_table_set_range)
2285 (char_table_set_range, optimize_sub_char_table)
2286 (map_sub_char_table):
2287 Use bool for boolean.
2288 * character.c (str_to_unibyte): Omit last boolean argument; it was
2289 always 0. All callers changed.
2290 * character.h, charset.h: Adjust to match previous changes.
2291 * character.h (char_printable_p): Remove decl of nonexistent function.
2292 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
2293 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
2294 are all boolean, so make them single-bit bitfields.
2296 * lisp.h (ASET): Remove attempt to detect side effects.
2297 It was meant to be temporary and it often doesn't work,
2298 because when IDX has side effects the behavior of IDX==IDX
2299 is undefined. See Stefan Monnier in
2300 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
2302 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
2304 * lisp.h (functionp): New function (extracted from Ffunctionp).
2305 (FUNCTIONP): Use it.
2306 * eval.c (Ffunctionp): Use it.
2308 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
2310 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
2311 as that's faster and simpler than static storage. Don't bother
2312 with the g_main_context_query overhead if g_main_context_pending
2313 says no events are pending.
2314 (gfds, gfds_size): Remove these static vars.
2315 (xgselect_initialize): Remove; no longer needed.
2316 All uses and decls removed.
2318 * emacs.c (fatal_error_signal_hook): Remove.
2319 All uses removed. This leftover from old code was always 0.
2321 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
2322 * casefiddle.c (casify_object, casify_region):
2323 * casetab.c (set_case_table):
2324 * category.c, category.h (word_boundary_p):
2325 * category.h (CHAR_HAS_CATEGORY):
2326 Use bool for booleans, instead of int.
2328 2012-08-25 Eli Zaretskii <eliz@gnu.org>
2330 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
2332 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
2334 On assertion failure, print backtrace if available.
2335 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
2336 (die) [ENABLE_CHECKING]: Print a backtrace if available.
2337 * Makefile.in (LIB_EXECINFO): New macro.
2340 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
2341 * bytecode.c (exec_byte_code):
2342 * callint.c (check_mark, Fcall_interactively):
2343 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
2344 (getenv_internal, sync_process_alive, call_process_exited):
2345 * lisp.h (USE_SAFE_ALLOCA):
2346 Use bool for booleans, instead of int.
2347 * lisp.h, process.h: Adjust prototypes to match above changes.
2348 * callint.c (Fcall_interactively): Don't assume the mark's
2349 offset fits in 'int'.
2351 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
2353 * buffer.c, buffer.h: Use bool for boolean.
2354 * buffer.c (reset_buffer_local_variables)
2355 (buffer_lisp_local_variables, Fset_buffer_modified_p)
2356 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
2357 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
2358 (overlay_touches_p, overlay_strings, Foverlay_put)
2359 (report_overlay_modification, call_overlay_mod_hooks):
2360 (mmap_enlarge, mmap_set_vars):
2361 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
2362 Use bool for booleans, instead of int.
2363 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
2364 since the 1-or-0 return value is always ignored anyway.
2365 (mmap_initialized_p):
2366 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
2367 * buffer.h, lisp.h: Adjust prototypes to match above changes.
2369 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
2371 * bidi.c: Use bool for boolean.
2372 This is a bit more readable, and makes the text segment of bidi.o
2373 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
2374 Presumably it's faster too.
2375 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
2377 (bidi_cache_find_level_change, bidi_cache_iterator_state)
2378 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
2379 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
2380 (bidi_explicit_dir_char, bidi_level_of_next_char)
2381 (bidi_find_other_level_edge, bidi_move_to_visually_next):
2382 Use bool for booleans, instead of int.
2383 * dispextern.h (bidi_init_it, bidi_paragraph_init)
2384 (bidi_unshelve_cache): Adjust decls to match code.
2386 2012-08-23 Martin Rudalics <rudalics@gmx.at>
2388 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
2391 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
2393 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
2394 * atimer.h: Include <stdbool.h>.
2396 2012-08-22 Dan Nicolaescu <dann@gnu.org>
2398 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
2399 compile time tests instead of run time tests on systems that do
2401 (FRAME_MAC_P): Remove leftover from deleted code.
2402 * frame.c (syms_of_frame): Remove leftover from deleted code.
2404 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
2406 * nsterm.m (insertText:): Don't clear modifiers if code is space.
2408 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
2410 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
2411 Otherwise, the compiler complains about (A?B:C) where B is void
2412 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
2413 (fontset_add): Return void, for FONTSET_ADD.
2415 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2417 * alloc.c: Use bool for booleans.
2418 (gc_in_progress, abort_on_gc)
2419 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
2420 (dont_register_blocks) [GC_MALLOC_CHECK]:
2421 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
2422 (check_string_bytes, make_specified_string, memory_full)
2423 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
2424 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
2425 (mark_stack, valid_pointer_p, make_pure_string)
2426 (Fgarbage_collect, survives_gc_p, gc_sweep):
2427 Use bool for booleans, instead of int.
2428 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
2429 Remove unused local.
2430 * alloc.c (PURE_POINTER_P):
2431 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
2432 * editfns.c (Fformat):
2433 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
2435 * fns.c (sweep_weak_table):
2436 * lisp.h (suppress_checking, push_message, survives_gc_p)
2437 (make_pure_string, gc_in_progress, abort_on_gc):
2438 * lread.c (readchar, read1):
2439 * print.c (Fprin1_to_string):
2440 * xdisp.c (push_message):
2441 Use bool for booleans affected directly or indirectly by
2444 Make recently-introduced setters macros.
2445 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
2446 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
2447 (set_fontset_default, set_fontset_fallback): Rename from their
2448 upper-case counterparts, and make them functions rather than macros.
2449 This is more consistent with the other recently-introduced setters.
2450 These don't need to be inline, since they're local.
2452 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
2454 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
2455 the loop (Bug#12247).
2457 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2459 * lisp.h (vcopy): Use memcpy rather than our own loop.
2460 This fixes a performance regression introduced by the recent
2461 addition of vcopy. This means 'vcopy' will need to be modified
2462 for a copying collector, but that's OK. Also, tighten the
2463 checking in the assertion.
2465 2012-08-21 Eli Zaretskii <eliz@gnu.org>
2467 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
2468 components for RTL text (Bug#11860). Adjust X-OFFSET of each
2469 non-base glyph for the width of the base character, according to
2470 what x_draw_composite_glyph_string_foreground expects.
2471 Generate WADJUST value according to composition_gstring_width's
2472 expectations, to produce correct width of the composed character.
2473 Reverse the sign of the DU offset produced by ScriptPlace.
2475 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2477 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
2479 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2481 Avoid direct writes to contents member of struct Lisp_Vector.
2482 * lisp.h (vcopy): New function to copy data into vector.
2483 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
2484 * fns.c (Ffillarray): Use ASET.
2485 * keyboard.c (timer_check_2): Use AREF and ASET.
2486 (append_tool_bar_item, Frecent_keys): Use vcopy.
2487 * lread.c (read_vector): Use ASET.
2488 * msdos.c (Frecent_doskeys): Use vcopy.
2489 * xface.c (Finternal_copy_lisp_face): Use vcopy.
2490 (Finternal_merge_in_global_face): Use ASET and vcopy.
2491 * xfont.c (xfont_list_pattern): Likewise.
2493 2012-08-21 Martin Rudalics <rudalics@gmx.at>
2495 * window.c (Fwindow_point): For the selected window always return
2496 the position of its buffer's point.
2497 (Fset_window_point): For the selected window always go in its
2498 buffer to the specified position.
2500 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2502 Setter macros for fontsets.
2503 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
2504 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
2505 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
2508 2012-08-20 Glenn Morris <rgm@gnu.org>
2510 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
2511 Don't assume that `ln -f' works.
2513 2012-08-20 Eli Zaretskii <eliz@gnu.org>
2515 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
2516 and later about non-assignments with no effect. See discussion at
2517 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
2520 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2522 Inline setter functions for Lisp_Objects slots of struct specbinding.
2523 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
2526 2012-08-20 Martin Rudalics <rudalics@gmx.at>
2528 * window.c (select_window): Always make selected window's buffer
2531 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2533 Use AREF and ASET for docstrings of category tables.
2534 * category.h (CATEGORY_DOCSTRING): Use AREF.
2535 (SET_CATEGORY_DOCSTRING): Use ASET.
2536 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
2538 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2540 Inline setter functions for hash table members.
2541 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
2542 (set_hash_hash, set_hash_index): Rename with _slot suffix.
2543 (set_hash_key_and_value, set_hash_index, set_hash_next)
2544 (set_hash_hash): New functions.
2545 * charset.c, fns.c: Adjust users.
2547 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2549 Inline getter and setter functions for per-buffer values.
2550 * buffer.h (per_buffer_default, set_per_buffer_default)
2551 (per_buffer_value, set_per_buffer_value): New functions.
2552 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
2553 * buffer.c, data.c: Adjust users.
2555 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
2557 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
2559 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
2561 Rely on <config.h> + <unistd.h> to declare 'environ',
2562 as gnulib does this if the system doesn't.
2563 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
2564 Remove declaration. MS-Windows declares it on stdlib.h which is
2565 included by conf_post.h.
2566 * emacs.c (environ) [DOUG_LEA_MALLOC]:
2567 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
2568 * vm-limit.c: Include <unistd.h>, for 'environ'.
2570 * unexaix.c, unexcoff.c: Include "mem-limits.h".
2571 (start_of_data): Remove decl; mem-limits.h provides it.
2573 * xdisp.c (handle_invisible_prop): Make it a bit faster
2574 and avoid a gcc -Wmaybe-uninitialized diagnostic.
2576 2012-08-19 Chong Yidong <cyd@gnu.org>
2578 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
2581 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
2583 * .gdbinit: Use call instead of set when calling a function in the
2586 * data.c (set_internal): Don't use set_blv_found.
2587 (Fkill_local_variable): Likewise.
2589 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
2591 * nsfont.m (ns_ascii_average_width): Ensure the string
2592 ascii_printable is initialized with a null-terminated character
2593 array. Otherwise, it can contain undesired extra characters.
2595 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
2597 port new setting code to Sun C 5.8 2005/10/13
2598 * chartab.c, lisp.h (char_table_set, char_table_set_range):
2599 Return void, not Lisp_Object. Otherwise, the compiler
2600 complains about (A?B:C) where B is void and C is Lisp_Object
2601 when compiling CHAR_TABLE_SET, due to the recent change to
2602 the API of sub_char_table_set_contents.
2604 2012-08-18 Chong Yidong <cyd@gnu.org>
2606 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
2607 for the string case (Bug#3874).
2609 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
2611 * buffer.h (BSET): Remove (Bug#12215).
2612 Replace all uses with calls to new setter functions.

2640 * category.c (bset_category_table):
2641 * syntax.c (bset_syntax_table):
2642 New setter functions.
2644 * process.h (PSET): Remove (Bug#12215).
2645 Replace all uses with calls to new setter functions.

2647 (PROCESS_INLINE): New macro.
2648 (pset_childp): New setter function.
2649 (pset_gnutls_cred_type) [HAVE_GNUTLS]: New setter function.
2650 * process.c (PROCESS_INLINE):
2651 Define to EXTERN_INLINE, so that the corresponding functions
2652 are compiled into code.

2656 (pset_plist, pset_sentinel, pset_status, pset_tty_name)
2657 (pset_type, pset_write_queue): New setter functions.
2659 * window.h (WSET): Remove (Bug#12215).
2660 Replace all uses with calls to new setter functions.
2661 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
2662 (WINDOW_INLINE): New macro.

3439 value of EMACSLOADPATH, as it is no longer needed.
3440 (check_windows_init_file): Now external, not static.

3446 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

3491 * alloc.c (record_xmalloc): New function.
3492 * lisp.h (record_xmalloc): New decl.
3493 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
3494 more like a function. This is because the pointer cast is not
3495 needed. All uses changed.
3496 * print.c (print_string, print_error_message): Avoid length recalc.
3498 Improve fix for macroexp crash with debugging (Bug#12118).
3499 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to

3503 (gc_aset): New function, which is like ASET but can be
3504 used in the garbage collector.

3533 with addition of handling of symlinks and support for 'lstat'.
3534 If possible, get file's attributes and security information by
3535 handle, not by name. Produce S_IFLNK bit for symlinks, when
3536 called from 'lstat'.
3537 (stat, lstat): New functions, call 'stat_worker'.
3538 (symlink, readlink, careadlinkat): Rewritten to create and resolve
3539 symlinks when the underlying filesystem supports them.
3541 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
3543 Fix macroexp crash on Windows with debugging (Bug#12118).
3544 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
3545 checking subscripts; problem introduced with the recent
3546 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
3547 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
3548 since it's used in non-static inline functions now.
3550 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
3551 Don't assume buffer size fits in 'int'. Remove unused local.

4012 * dbusbind.c (XD_DBUS_VALIDATE_BUS_ADDRESS): Canonicalize session
4014 (xd_close_bus, Fdbus_init_bus): Handle reference counter properly.
4016 2012-07-27 Eli Zaretskii <eliz@gnu.org>
4018 * alloc.c (listn): Fix the order the arguments are consed onto the
4021 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
4022 enumeration constants, as PURE and HEAP are too general, and clash
4023 with other headers and sources, such as gmalloc.c and the
4024 MS-Windows system headers. All users changed.
4026 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
4028 Revert last save_excursion_save and save_excursion_restore changes.
4029 * alloc.c, editfns.c, marker.c, lisp.h: Revert.
4030 Lots of crashes reported by Chong Yidong <cyd@gnu.org>.
4032 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
4034 Fix recently-introduced typos in Windows port.
4035 Reported by Martin Rudalics <rudalics@gmx.at>.

4039 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
4041 Improve GDB symbol export (Bug#12036).
4042 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
4043 arms of an 'if', not using conditional expressions; otherwise GDB
4044 complains about the types in the unevaluated arm when the argument
4045 is an integer literal.
4046 (xgetint): Simplify expression.
4047 * alloc.c (gdb_make_enums_visible): New constant. This ports to
4048 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
4049 Zaretskii in <http://bugs.gnu.org/12036#13>.
4050 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
4051 needed now that we have gdb_make_enums_visible.
4052 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
4053 (enum enum_USE_LSB_TAG):
4054 New enum types, packaging up enums that need to be exported to GDB.
4056 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
4058 Utility function to make a list from specified amount of objects.
4059 * lisp.h (enum constype): New datatype.
4060 (listn): New prototype.
4061 * alloc.c (listn): New function.
4062 (Fmemory_use_count, syms_of_alloc): Use it.

4070 * w32.c (init_environment): Likewise.
4071 * w32fns.c (Fw32_battery_status, syms_of_w32fns): Likewise.
4072 * xdisp.c (syms_of_xdisp): Likewise.
4073 * xfns.c (syms_of_xfns): Likewise.
4075 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
4077 Fast save_excursion_save and save_excursion_restore.
4078 * lisp.h (struct Lisp_Excursion): New data type.
4079 (PVEC_EXCURSION): New pseudovector type.
4080 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
4081 to deal with it. Adjust comments.
4082 (init_marker, attach_marker): New prototype.
4083 (unchain_marker): Adjust prototype.
4084 * marker.c (attach_marker): Change to global.

4088 (mark_object): Handle struct Lisp_Excursion.
4089 * editfns.c (save_excursion_save, save_excursion_restore):
4090 Reimplement to use struct Lisp_Excursion. Add comments.
4092 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
4094 Fix export of symbols to GDB (Bug#12036).
4095 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
4096 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
4097 emacs.c, as this is a more-suitable home. Had this been done earlier
4098 the fix for 12036 would have avoided some of the problems noted in
4099 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
4100 would have been more obvious.
4101 * emacs.c: Do not include <verify.h>; no longer needed.
4102 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
4103 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
4104 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
4105 Remove; now done in lisp.h.
4106 * lisp.h (PUBLISH_TO_GDB): New macro.
4107 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
4108 (DATA_SEG_BITS): Use it.
4109 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
4110 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
4111 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
4112 not be usable in #if. This simplifies things.
4114 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
4116 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
4118 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
4120 Simplify export of symbols to GDB (Bug#12036).
4121 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
4122 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
4123 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
4124 Adjust to changes in lisp.h and emacs.c, by using
4125 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
4126 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
4127 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
4128 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
4129 instead of gdb_valbits.
4130 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
4131 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
4132 instead of gdb_array_mark_flag.
4133 (xboolvector): Get size from $->size, not $->header.size.
4134 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
4135 (xreload, hook-run, hookpost-run): Remove.
4136 * emacs.c: Include <verify.h>.
4137 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
4138 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
4140 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
4141 (gdb_USE_LSB_TAG): New enum constants.
4142 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
4143 Also define these as enum constants, so they're visible to GDB.
4144 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
4145 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
4146 as constants, so they're visible to GDB.
4147 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
4148 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
4149 Now enum constants, not macros, so they're visible to GDB.
4150 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
4151 more convenient now. All uses changed.
4152 (VALMASK) [USE_LSB_TAG]: Also define in this case.
4153 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
4155 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
4157 Explicitly free restriction data that are not needed anymore.
4158 * editfns.c (save_restriction_restore): Free restriction data.
4160 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
4162 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
4163 add argument, tune behavior, and adjust all callers.
4165 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
4167 Use typedef for EMACS_INT, EMACS_UINT.
4168 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
4169 than macros. This simplifies debugging in the usual case, since
4170 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
4171 and it allows expressions involving EMACS_INT casts.
4172 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
4174 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
4176 * nsterm.m (ns_read_socket): Return early if there is a modal
4179 2012-07-25 Martin Rudalics <rudalics@gmx.at>

4182 that FOCUS-FRAME can be omitted.
4184 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
4186 Adjust buffer text indirection counters at the end of Fkill_buffer.
4187 * buffer.c (Fkill_buffer): Adjust indirection counters when the
4188 buffer is definitely dead. This should really fix an issue reported
4189 by Christoph Scholtes again. (Bug#12007).
4190 (init_buffer_once): Initialize indirection counters of
4191 buffer_defaults and buffer_local_symbols (for sanity and safety).
4193 2012-07-24 Eli Zaretskii <eliz@gnu.org>
4195 * xdisp.c (init_iterator): Don't compute dimensions of truncation
4196 and continuation glyphs on tooltip frames, leave them at zero.
4197 Avoids continued lines in tooltips. (Bug#11832)
4199 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
4201 Simplify copy_overlay.
4202 * buffer.c (copy_overlay): Simplify. Use build_marker.
4203 * lisp.h (struct Lisp_Overlay): Restore comment with minor tweaks.
4205 2012-07-23 Eli Zaretskii <eliz@gnu.org>
4207 * print.c (print_object): Don't crash when a frame's name is nil
4208 or invalid. (Bug#12025)
4210 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
4211 it signals an error when a tooltip frame is being created.
4213 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
4215 Cleanup miscellaneous objects allocation and initialization.
4216 * alloc.c (allocate_misc): Change to static. Add argument to
4217 specify the subtype. Adjust comment and users.
4218 (build_overlay): New function.
4219 * buffer.c (copy_overlays, Fmake_overlay): Use it.
4220 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.

4222 (build_overlay): Add prototype.
4224 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
4226 Swap buffer text indirection counters in Fbuffer_swap_text.
4227 * buffer.c (Fbuffer_swap_text): Swap indirections too.
4228 This avoids crash reported by Christoph Scholtes at
4229 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
4231 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
4233 * nsmenu.m (Popdown_data): New struct.
4234 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
4236 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
4237 (initWithContentRect): Make imgView and contentView non-static
4238 and autorelease them. Also autorelease img and matrix (Bug#12005).
4239 (dealloc): Remove (Bug#12005).
4241 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
4243 Adjust consing_since_gc when objects are explicitly freed.
4244 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
4245 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.
4246 (free_cons, free_misc): Subtract object size from consing_since_gc.
4248 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
4250 Simplify and cleanup markers positioning code.
4251 * marker.c (attach_marker): More useful eassert.
4252 (live_buffer, set_marker_internal): New function.
4253 (Fset_marker, set_marker_restricted): Use set_marker_internal.
4254 (set_marker_both, set_marker_restricted_both): Use live_buffer.
4256 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
4258 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
4259 as it's limited by the amount of memory, not by INT_MAX.
4261 2012-07-21 Eli Zaretskii <eliz@gnu.org>
4263 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
4264 in special-event-map. See the discussion at
4265 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
4268 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning

4286 * buffer.h (struct buffer): New member.
4287 * buffer.c (Fget_buffer_create): Set indirection counter to 0.
4288 (Fmake_indirect_buffer): Set indirection counter to -1, increment
4289 base buffer indirection counter.
4290 (compact_buffer): If ENABLE_CHECKING, verify indirection counters.

4321 * dosfns.c, fileio.c, fns.c, ftfont.c, process.c:
4322 * sysdep.c, w32fns.c, xfns.c: Use it.
4323 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
4324 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
4325 Adjust users accordingly.
4326 * font.h (font_open_by_name): Adjust prototype.
4328 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>

4337 * bytecode.c (MAYBE_GC): Use maybe_gc.
4338 * eval.c (eval_sub, Ffuncall): Likewise.

4340 to avoid dependency from auto-save feature.
4342 2012-07-19 Paul Eggert <eggert@cs.ucla.edu>
4344 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
4345 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
4346 'for_each_per_buffer_object_at'.
4347 All uses changed. It's better to use upper-case for macros that
4348 cannot be implemented as functions, to give the reader a clue
4349 that they're special.
4351 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
4353 * alloc.c (Fgarbage_collect): Tweak docstring.

4394 * intervals.c (merge_interval_right, merge_interval_left):
4395 Do not zero out this interval if it is absorbed by its children,
4396 as this interval's total length doesn't change in that case. See
4397 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
4399 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
4401 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
4402 when invoking (make-bool-vector N t) and N is a positive
4403 multiple of 8 -- the last 8 bits were mistakenly cleared.
4405 Remove some struct layout assumptions in bool vectors.
4406 * alloc.c (bool_header_size): New constant.
4407 (header_size, word_size): Move earlier, as they're now used earlier.
4408 Use 'word_size' in a few more places, where it's appropriate.
4409 (Fmake_bool_vector, sweep_vectors): Don't assume that there is no
4410 padding before the data member of a bool vector.
4411 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
4412 than doing the check by hand with an abort ().
4414 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
4416 * eval.c (Fdefvar): Don't check constants since we only set the var if
4417 it's not yet defined anyway (bug#11904).
4419 * lisp.h (last_undo_boundary): Declare new var.
4420 * keyboard.c (command_loop_1): Set it.
4421 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
4422 were auto-added by the command loop (bug#11774).
4424 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
4426 * w32font.c (Qsymbol): Remove local definition.

4915 2012-07-11 Glenn Morris <rgm@gnu.org>
4917 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
4918 since nothing has defined it on these platforms.
4920 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/gnu-linux.h:
4921 * s/irix6-5.h: Move SIGNALS_VIA_CHARACTERS to configure.

4924 * s/gnu-linux.h, s/hpux10-20.h, s/template.h, s/usg5-4-common.h:
4925 Move CLASH_DETECTION to configure.
4927 * s/gnu.h: Remove file, which is now empty.
4929 * s/gnu.h, s/gnu-linux.h:
4930 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
4932 2012-07-11 John Wiegley <johnw@newartisans.com>
4934 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
4935 function attribute, so we only use it if it exists in the
4938 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
4940 Avoid call to strlen in fast_c_string_match_ignore_case.
4941 * search.c (fast_c_string_match_ignore_case): Change to use
4942 length argument. Adjust users accordingly.
4943 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
4945 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>
4947 Assume mkdir, rmdir.

4962 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
4964 Avoid calls to strlen in font processing functions.
4965 * font.c (font_parse_name, font_parse_xlfd, font_parse_fcname)
4966 (font_open_by_name): Change to use length argument.
4967 Adjust users accordingly.
4968 * font.h (font_open_by_name, font_parse_xlfd, font_unparse_xlfd):
4970 * xfont.c (xfont_decode_coding_xlfd, font_unparse_xlfd):
4971 Change to return ptrdiff_t.
4972 (xfont_list_pattern, xfont_match): Use length returned by
4973 xfont_decode_coding_xlfd.

4984 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
4986 Remove "#define unix" that is no longer needed (Bug#11905).
4987 * s/aix4-2.h (unix): Remove; no longer needed.
4989 EMACS_TIME simplification (Bug#11875).
4990 This replaces macros (which typically do not work in GDB)
4991 with functions, typedefs and enums, making the code easier to debug.
4992 The functional style also makes code easier to read and maintain.
4993 * systime.h: Include <sys/time.h> on all hosts, not just if
4994 WINDOWSNT, since 'struct timeval' is needed in general.
4995 (EMACS_TIME): Now a typedef, not a macro.
4996 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
4998 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

5000 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
5001 (EMACS_TIME_LE): Now functions, not macros.
5002 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
5003 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
5004 which are not functions. All uses rewritten to use:
5005 (make_emacs_time): New function.
5006 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
5007 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
5008 not functions. All uses rewritten to use the following, respectively:
5009 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
5010 (add_emacs_time, sub_emacs_time): New functions.
5011 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
5012 * fileio.c (Fcopy_file):
5013 * xterm.c (XTflash): Get the current time closer to when it's used.
5014 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

5021 * frame.c (Fmake_terminal_frame):
5022 * gtkutil.c (get_utf8_string):
5024 * nsmenu.m (ns_update_menubar):
5025 * regex.c (regerror):
5026 Prefer memcpy to strncpy and strncat when either will do.
5027 * fileio.c (Fsubstitute_in_file_name):
5028 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
5029 (menu_separator_name_p):
5030 * nsmenu.m (ns_update_menubar):
5031 Prefer memcmp to strncmp when either will do.
5032 * nsterm.m: Include <ftoastr.h>.
5034 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
5035 Prefer snprintf to strncpy.
5036 * nsterm.m (ns_term_init):
5037 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
5038 * nsterm.m (ns_term_init):
5039 Avoid the need for strncpy, by using build_string or
5040 make_unibyte_string directly. Use dtoastr, not snprintf.
5041 * process.c (Fmake_network_process): Diagnose service names that
5042 are too long, rather than silently truncating them or creating
5043 non-null-terminated names.
5044 (Fnetwork_interface_info): Likewise, for interface names.
5045 * sysdep.c (system_process_attributes) [GNU_LINUX]:
5046 Prefer sprintf to strncat.
5047 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
5048 Prefer vsnprintf to vsprintf + strncpy.
5050 2012-07-10 Glenn Morris <rgm@gnu.org>
5052 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
5053 Clarify fallback case.
5055 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
5057 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
5058 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
5059 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
5060 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
5061 where argument type is known to be a Lisp_Cons.
5063 2012-07-10 Tom Tromey <tromey@redhat.com>
5065 * bytecode.c (BYTE_CODE_THREADED): New macro.
5066 (BYTE_CODES): New macro. Replaces all old byte-code defines.

5071 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
5073 Optimize pure C strings initialization.
5074 * lisp.h (make_pure_string): Fix prototype.
5075 (build_pure_c_string): New function, defined as static inline. This
5076 provides a better opportunity to optimize away calls to strlen when
5077 the function is called with compile-time constant argument.
5078 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
5079 argument, adjust users accordingly. Use build_pure_c_string where
5081 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
5082 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
5083 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
5085 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
5087 Avoid calls to strlen in miscellaneous functions.
5088 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
5089 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
5090 * lread.c (openp): Likewise.
5092 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
5094 Avoid calls to strlen in path processing functions.
5095 * fileio.c (file_name_as_directory): Add comment. Change to add
5096 srclen argument and return the length of result. Adjust users
5098 (directory_file_name): Fix comment. Change to add srclen argument,
5099 swap 1st and 2nd arguments to obey the common convention.
5100 Adjust users accordingly.
5101 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
5103 2012-07-10 Glenn Morris <rgm@gnu.org>
5105 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
5106 Move PENDING_OUTPUT_COUNT definition to configure.
5108 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
5109 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
5110 * s/gnu.h (DATA_START): Move definitions to configure.
5112 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
5113 We include usg5-4-common.h, which defines them both.
5115 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
5116 O_RDONLY already includes it).
5118 Stop ns builds setting the EMACSLOADPATH environment variable.
5119 * nsterm.m (ns_load_path): Rename from ns_init_paths.
5120 Now it does not set EMACSLOADPATH, just returns the load-path string.
5121 * nsterm.h: Update accordingly.
5122 * lread.c [HAVE_NS]: Include nsterm.h.
5123 (init_lread) [HAVE_NS]: Use ns_load_path.
5124 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
5126 2012-07-09 Glenn Morris <rgm@gnu.org>
5128 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
5129 since the included bsd-common.h does so.
5131 Stop ns builds setting the EMACSPATH environment variable.
5132 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
5133 (ns_init_paths): Do not set EMACSPATH.
5134 * nsterm.h (ns_exec_path): Add it.
5135 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
5138 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
5140 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
5142 * process.c (wait_reading_process_output): 'waitchannels' was unset
5143 when read_kbd || !NILP (wait_for_cell); fix this.
5145 Add GCC-style 'const' attribute to functions that can use it.
5146 * character.h (char_resolve_modifier_mask):
5147 * keyboard.h (make_ctrl_char):
5148 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
5149 (init_character_once, next_almost_prime, init_fns, init_image)
5150 (flush_pending_output, init_sound):
5151 * mem-limits.h (start_of_data):
5152 * menu.h (finish_menu_items):
5153 Add ATTRIBUTE_CONST.

5155 Declare the dummy function with ATTRIBUTE_CONST.
5156 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
5157 Add decls with ATTRIBUTE_CONST.
5159 Minor improvements to make_formatted_string.
5160 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
5161 where int is good enough, as vsprintf returns an int.
5162 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
5164 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
5166 Use make_formatted_string to avoid double length calculation.
5167 * lisp.h (make_formatted_string): New prototype.
5168 * alloc.c (make_formatted_string): New function.
5169 * buffer.c (Fgenerate_new_buffer_name): Use it.
5170 * dbus.c (syms_of_dbusbind): Likewise.

5173 * frame.c (make_terminal_frame, set_term_frame_name)
5174 (x_report_frame_params): Likewise.
5175 * image.c (gs_load): Likewise.
5176 * minibuf.c (get_minibuffer): Likewise.

5191 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
5193 Move marker debugging code under MARKER_DEBUG.
5194 * marker.c (MARKER_DEBUG): Move marker debugging code under
5195 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
5196 for bootstrap with --enable-checking (~3x slowdown reported
5197 by Juanma Barranquero <lekktu@gmail.com>).
5198 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
5200 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
5202 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
5203 See <http://bugs.gnu.org/11825#29>.
5205 2012-07-08 Eli Zaretskii <eliz@gnu.org>
5207 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
5208 has no font, use the frame's font. (Bug#11813)
5209 (display_line): Add commentary about displaying truncation glyphs
5211 (produce_special_glyphs): Move here from term.c.
5213 * term.c (produce_special_glyphs): Move to xdisp.c.
5215 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
5218 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
5220 * xdisp.c (display_line): Avoid warning about implicit declaration
5223 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
5225 * lisp.h: Remove empty conditional.
5227 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
5229 * lread.c (load_path_check): Now static.
5231 Fix some minor --with-ns problems found by static checking.
5232 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
5233 (x_set_font) [!HAVE_X_WINDOWS]:
5234 * image.c (xpm_load_image) [HAVE_NS]:
5235 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
5236 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
5237 Remove unused local.
5238 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
5239 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
5240 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
5241 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
5242 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
5243 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
5244 Fix pointer signedness problem.
5245 * xfaces.c (FRAME_X_FONT_TABLE):
5246 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
5248 2012-07-07 Glenn Morris <rgm@gnu.org>
5250 * lread.c (load_path_check): New function, split from init_lread.
5251 (init_lread): Reorganize. Motivation:
5252 If EMACSLOADPATH is set, check/warn about that rather than the
5253 defaults, which we are not going to use. Hence we can remove
5254 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
5255 Don't warn if site-lisp directories are missing.
5256 If not installed, start from a blank load-path, since
5257 PATH_LOADSEARCH refers to the eventual installation directories.
5259 2012-07-07 Eli Zaretskii <eliz@gnu.org>
5261 Support truncation and continuation glyphs on GUI frames, when
5262 fringes are disabled. (Bug#11832)
5263 * xdisp.c (init_iterator): Get dimensions of truncation and
5264 continuation glyphs even if on GUI frames.
5265 Adjust it->last_visible_x on GUI frames when the left or right fringes,
5266 or both, are absent.
5267 (start_display, move_it_in_display_line_to): Handle the case of a
5268 GUI frame without a fringe to display continuation or truncation
5270 (insert_left_trunc_glyphs): Support GUI frames: make sure
5271 truncation glyphs overwrite enough glyphs from the current line to
5272 have sufficient space in pixels.
5273 (display_line): Support truncation and continuation glyphs on GUI
5274 frames. If some spare pixels are left on the line after inserting
5275 the truncation glyphs, fill that space with a stretch glyph of a
5276 suitably computed width.
5278 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
5279 produce_glyphs, to support GUI sessions.
5281 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
5283 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
5285 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
5287 Do not require float-time's arg to fit in time_t (Bug#11825).
5288 This works better on hosts where time_t is unsigned, and where
5289 float-time is applied to the (negative) difference between two times.
5290 * editfns.c (decode_time_components): Last arg is now double *,
5291 not int *, and means to store all the result as a double, without
5292 worrying about whether the seconds part fits in time_t.
5293 All callers changed.
5294 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
5295 All callers changed.
5296 (Ffloat_time): Do not fail merely because the specified time falls
5297 outside of time_t range.
5299 2012-07-07 Glenn Morris <rgm@gnu.org>
5301 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
5302 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

5305 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
5307 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
5308 Update dependencies.
5310 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
5312 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5314 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
5315 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
5316 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
5317 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
5318 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
5319 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
5321 * xfont.c (compare_font_names): Redo to omit the need for casts.
5323 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
5325 * xfns.c (Fx_change_window_property): Doc fix.
5326 * w32fns.c (Fx_change_window_property): Doc fix.
5328 * w32fns.c (Fx_window_property): Accept the same arguments as the
5329 X Windows version. Doc fix.
5330 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
5332 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
5333 Eli Zaretskii <eliz@gnu.org>
5335 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
5336 Windows-specific code from nt/config.nt moved here.
5337 Obsolete settings removed.
5339 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5341 * process.c: Avoid unnecessary calls to gettime.
5342 (wait_reading_process_output): Don't get the time of day
5343 when gobbling data immediately and not waiting, as there's no need
5344 for it in that case. This removes a FIXME.
5346 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
5348 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
5349 is defined (Bug#11768).

5353 Fix marker debugging code.
5354 * marker.c (byte_char_debug_check): Do not perform the check
5355 if buffer is not multibyte.
5356 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
5357 Call byte_char_debug_check with correct arguments.
5359 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5361 Compile marker debugging code only if ENABLE_CHECKING is defined.
5362 * marker.c (byte_char_debug_check, count_markers):
5363 Use only if ENABLE_CHECKING is defined.
5364 (byte_debug_flag): Remove.
5365 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
5366 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
5368 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5370 Avoid code repetition in marker-related functions.
5371 * marker.c (attach_marker): New function.

5374 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
5375 Consistently rename charno to charpos.
5376 (marker_position): Add eassert.
5377 (marker_byte_position): Convert to eassert.
5379 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

5389 * lisp.h (build_marker): New prototype.
5390 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
5391 * composite.c (autocmp_chars): Likewise.
5392 * editfns.c (buildmark): Remove.
5393 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
5394 (save_restriction_save): Use build_marker.
5395 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
5396 * window.c (save_window_save): Likewise.
5398 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

5403 (delete_all_overlays, Fdelete_overlay): Use it.
5404 * minibuf.c (get_minibuffer): Fix comment.
5406 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5408 Port to OpenBSD 5.1 amd64.
5409 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
5410 This is needed for OpenBSD, and should be harmless on all BSD systems.
5411 Also, include <sys/sysctl.h>, as it should be available on all
5412 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
5413 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
5414 use p_pid member, not kp_proc.pid.
5416 2012-07-06 Glenn Morris <rgm@gnu.org>
5418 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
5420 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5422 More xmalloc and related cleanup.
5423 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

5431 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
5433 Omit needless casts involving void * pointers and allocation.
5434 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
5435 as the former is more robust if P's type is changed.
5436 Prefer xzalloc to xmalloc + memset 0.
5437 Simplify malloc-or-realloc to realloc.
5438 Don't worry about xmalloc returning a null pointer.
5439 Prefer xstrdup to xmalloc + strcpy.
5440 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
5442 * keyboard.c (apply_modifiers_uncached): Prefer local array to
5443 alloca of a constant.
5445 2012-07-05 Eli Zaretskii <eliz@gnu.org>
5447 * xdisp.c (display_line): Fix horizontal pixel coordinates when
5448 hscroll is larger than the line width. Fixes long and futile
5449 looping inside extend_face_to_end_of_line (on a TTY) producing
5450 glyphs that are not needed and thrown away.
5452 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
5454 * marker.c (set_marker_restricted_both): Simplify by using

5466 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
5467 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
5468 followed by gtk_box_set_homogeneous (Bug#11768).
5469 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
5470 (update_theme_scrollbar_width, xg_create_scroll_bar):
5471 Use gtk_scrollbar_new (Bug#11768).
5472 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
5473 (is_box_type): New function (Bug#11768).
5474 (xg_tool_item_stale_p): Call is_box_type.
5475 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
5476 with default display (Bug#11768).

5480 * xdisp.c (window_hscroll_limited): New function.
5481 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
5482 coordinates when window's hscroll is set to insanely large
5485 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
5487 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

5548 * fileio.c (time_error_value): Check the right error number.
5549 Problem reported by Troels Nielsen in
5550 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
5552 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5554 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
5555 This should be fixed in a better way; see Eli Zaretskii in
5556 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
5557 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
5559 * fileio.c (time_error_value): Rename from special_mtime.
5560 The old name's problems were noted by Eli Zaretskii in
5561 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
5563 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
5564 This variable's comment says Emacs needs at least one GDB-visible
5565 symbol of type enum pvec_type, to work around GDB problems.
5566 The symbol's value doesn't matter.
5568 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
5569 that causes compilation to fail on pre-C99 compilers.
5571 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
5573 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
5574 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
5576 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5578 * buffer.c (init_buffer_once): Fix initialization of
5579 headers for buffer_defaults and buffer_local_symbols.
5580 Reported by Juanma Barranquero <lekktu@gmail.com>.

5584 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
5585 * lisp.h (enum pvec_type): Use fewer bits.
5586 (PSEUDOVECTOR_SIZE_BITS): New constant.
5587 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
5588 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
5589 change in pvec_type.
5590 (PSEUDOVECTOR_TYPEP): New macro.

5596 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
5597 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
5598 (sweep_vectors): Use it. Use local var `total_bytes' instead of
5599 abusing vector->header.next.nbytes.
5600 (live_vector_p): Use PVEC_TYPE.
5601 (mark_object): Adapt code to extract pvectype. Use switch.
5603 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5605 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
5606 Tighten new eassert a bit.
5608 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5610 Fix compilation with --enable-gcc-warnings and -O1
5612 * doprnt.c (doprnt): Change type of tem to int, initialize
5613 to avoid compiler warning. Add eassert.
5614 * search.c (simple_search): Initialize match_byte to avoid
5615 compiler warning. Add eassert.
5617 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5619 Avoid weird behavior with large horizontal scrolls.
5620 Without this change, for example, large hscroll values would
5621 mess up Emacs's display on Fedora 15 x86, presumably due to
5622 overflows in int calculations in the display code.
5623 Also, if buffers had long lines, Emacs would freeze.
5624 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
5625 (set_window_hscroll): New function, containing the old guts of
5626 Fset_window_hscroll. Return the clipped value.
5627 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
5628 This avoids the need to check against PTRDIFF_MAX.
5630 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
5632 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5634 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
5636 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5638 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
5639 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
5640 since GCC 4.4.6 issues a bogus warning for them.
5642 Fix bugs in file timestamp newness comparisons.
5643 * fileio.c (Ffile_newer_than_file_p):
5644 * lread.c (Fload): Use full timestamp resolution of files,
5645 not just the 1-second resolution, so that files that are only
5646 slightly newer still count as newer.
5647 * fileio.c (Ffile_newer_than_file_p): Don't assume file
5648 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
5650 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
5652 * fileio.c: Improve handling of file time marker. (Bug#11852)
5653 (special_mtime): New function.
5654 (Finsert_file_contents, Fverify_visited_file_modtime):
5655 Use it to set special mtime values consistently.
5657 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
5659 * fileio.c (Finsert_file_contents): Properly handle st_mtime
5660 marker for non-existing file. (Bug#11852)
5662 2012-07-03 Glenn Morris <rgm@gnu.org>
5664 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
5665 and did not make it into globals.h).
5667 2012-07-03 Tom Tromey <tromey@redhat.com>
5669 * window.c (Fset_window_margins, Fset_window_fringes)

5705 2012-07-03 Glenn Morris <rgm@gnu.org>
5707 * lisp.h (Frandom): Make it visible to C.
5708 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
5709 buffer for invisible buffers. (Bug#1229)

5713 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
5714 values which aren't power of 2.
5715 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
5716 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
5719 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
5721 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

5727 * alloc.c (allocate_vector_block): Remove redundant
5728 calls to mallopt if DOUG_LEA_MALLOC is defined.
5729 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
5730 avoid calls to mallopt if zero_vector is returned.
5732 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5734 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
5735 is enabled, avoid dereferencing NULL current_sblock if
5738 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5740 Cleanup basic buffer management.
5741 * buffer.h (struct buffer): Change layout to use generic vector
5742 marking code. Fix some comments. Change type of 'clip_changed'
5743 to bitfield. Remove unused #ifndef old.
5744 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
5745 (GET_OVERLAYS_AT): Fix indentation.

5750 * alloc.c (allocate_buffer): Adjust to match new layout of
5751 struct buffer. Fix comment.

5755 (mark_object): Use it. Adjust marking of misc objects
5756 and related comments.
5758 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
5760 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
5761 wrapper that is not needed because the wrapped code is a no-op (zero
5762 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
5763 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
5765 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
5767 * alloc.c (mark_buffer): Simplify. Remove prototype.
5768 (mark_object): Add comment. Reorganize marking of vector-like
5769 objects. Use CHECK_LIVE for all vector-like objects except buffers
5770 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
5771 Avoid redundant calls to mark_vectorlike for bool vectors.
5773 2012-06-30 Glenn Morris <rgm@gnu.org>
5775 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
5777 * epaths.in (PATH_SITELOADSEARCH): New.
5778 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
5779 This is rather than relying on --enable-locallisppath elements
5780 having "site-lisp" in their names. (Bug#10208#25, 11658)
5782 2012-06-30 Eli Zaretskii <eliz@gnu.org>
5784 * w32proc.c (sys_select): Accept and ignore one more argument.
5786 * w32.c (emacs_gnutls_pull): Call select with one more argument.

5793 * process.c (sys_select):
5794 * msdos.c (sys_select): Accept one more argument and ignore it.
5796 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
5797 adapt data types and code to that.
5800 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
5801 which clashes with the gnulib function of the same name.
5803 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
5805 * font.c (font_style_to_value, font_style_symbolic)

5816 * xdisp.c (try_window_id): Undo last change.
5818 * w32.c (getwd): Adjust commentary about startup_dir.
5819 (init_environment): Always call sys_access, even in non-MSVC
5820 builds. Don't chdir to the directory of the Emacs executable.
5821 This undoes code from 1997 which was justified by the need to
5822 "avoid conflicts when removing and renaming directories". But its
5823 downside was that every relative file name was being interpreted
5824 relative to the directory of the Emacs executable, which can never
5825 be TRT. In particular, it broke sys_access when called with
5826 relative file names.
5827 (sys_access): Map GetLastError to errno.
5829 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

6019 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
6021 Use sprintf return value instead of invoking strlen on result.
6022 In the old days this wasn't portable, since some sprintf
6023 implementations returned char *. But they died out years ago and
6024 Emacs already assumes sprintf returns int.
6025 Similarly for float_to_string.
6026 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

6034 Use sprintf or float_to_string result to avoid need to call strlen.
6035 * data.c (Fnumber_to_string):
6036 Use make_unibyte_string, since the string must be ASCII.
6037 * lisp.h, print.c (float_to_string): Now returns int length.
6038 * term.c (produce_glyphless_glyph):
6039 Use sprintf result rather than recomputing it.
6041 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
6042 * Makefile.in (ALL_CFLAGS):
6043 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

6074 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

6077 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
6079 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
6080 instead of truncating it to 63 (admittedly a generous limit).

6140 * keyboard.c (kbd_buffer_get_event):
6141 * process.c (Faccept_process_output):
6142 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
6143 This improves on the previous patch, which introduced a bug

6145 See <http://bugs.gnu.org/9000#51>.
6147 2012-06-23 Eli Zaretskii <eliz@gnu.org>

6210 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
6212 Support higher-resolution time stamps (Bug#9000).
6213 The time stamps are only nanosecond-resolution at the C level,
6214 since that's the best that any real-world system supports now.
6215 But they are picosecond-resolution at the Lisp level, as that's
6216 easy, and leaves room for future OS improvements.
6218 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
6221 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
6222 Don't get current time unless it's needed.
6224 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
6225 now provides it if it's absent.
6226 (start_atimer): Port to higher-res time stamps.
6227 Check for time stamp overflow. Don't get current time more
6228 often than is needed.
6230 * buffer.h (struct buffer): Buffer modtime now has high resolution.
6231 Include systime.h, not time.h.
6232 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
6234 * dired.c: Include stat-time.h.
6235 (Ffile-attributes): File times now have higher resolution.

6238 (struct image): Timestamp now has higher resolution.
6240 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
6241 has at least microseconds now. All uses removed.
6242 (update_frame, update_single_window, update_window, update_frame_1)
6243 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
6244 (duration_to_sec_usec): Remove; no longer needed.
6246 * editfns.c (time_overflow): Now extern.
6247 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
6248 (float-time, Fformat_time_string, Fcurrent_time_string)

6252 (decode_time_components, lisp_seconds_argument): New functions.
6253 (make_time): Now static.
6254 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
6255 Report an error if the time is invalid, rather than having the caller
6258 * fileio.c: Include <stat-time.h>
6259 (Fcopy_file): Copy higher-resolution time stamps.
6260 Prefer to set the time stamp via a file descriptor if that works.
6261 (Fset_file_times, Finsert_file_contents, Fwrite_region)
6262 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
6263 (Fvisited_file_modtime, Fset_visited_file_modtime):
6264 Support higher-resolution time stamps.
6266 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
6268 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
6270 * image.c (prepare_image_for_display, clear_image_cache)
6271 (lookup_image): Port to higer-resolution time stamps.
6273 * keyboard.c (start_polling, bind_polling_period):
6274 Check for time stamp overflow.
6275 (read_char, kbd_buffer_get_event, timer_start_idle)
6276 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
6277 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
6278 Port to higher-resolution time stamps. Do not assume time_t is signed.
6279 (decode_timer): New function. Timers are now vectors of length 9,
6280 not 8, to accommodate the picosecond component.
6281 (timer_check_2): Use it.
6283 * nsterm.m (select_timeout, timeval_subtract): Remove.
6284 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
6285 as they're a bit more accurate and handle overflow better.
6286 (ns_select): Change prototype to be compatible with pselect.
6287 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
6288 * nsterm.h (ns_select): Adjust prototype.
6290 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
6291 us-resolution time stamps.
6292 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
6294 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
6296 * lisp.h (time_overflow): New decl.
6297 (wait_reading_process_output): First arg is now intmax_t, not int,
6298 to accommodate larger waits.
6300 * process.h (struct Lisp_Process.read_output_delay):
6301 Now counts nanoseconds, not microseconds.
6302 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
6304 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
6305 (wait_reading_process_output):
6306 Port to ns-resolution time stamps.
6307 (Faccept_process_output, wait_reading_process_output):
6308 Check for time stamp overflow. Do not assume time_t is signed.
6309 (select_wrapper): Remove; we now use pselect.
6310 (Fprocess_attributes): Now generates ns-resolution time stamps.
6312 * sysdep.c: Include utimens.h. Don't include utime.h
6313 or worry about struct utimbuf; gnulib does that for us now.
6314 (gettimeofday): Remove; gnulib provides a substitute.
6315 (make_timeval): New function.
6316 (set_file_times): Now sets ns-resolution time stamps.
6317 New arg FD; all uses changed.
6318 (time_from_jiffies, ltime_from_jiffies, get_up_time)

6320 Now returns ns-resolution time stamp. All uses changed.
6321 Check for time stamp overflow.
6323 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
6324 provides a substitute now.
6326 * systime.h: Include timespec.h rather than sys/time.h and time.h,
6327 since it guarantees struct timespec.
6328 (EMACS_TIME): Now struct timespec, so that we can support
6329 ns-resolution time stamps.
6330 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
6331 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
6332 (EMACS_USECS): Remove.
6333 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
6334 so multiply the arg by 1000 before storing it.

6344 (make_timeval, make_lisp_time, decode_time_components): New decls.
6345 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
6346 that it mishandled time_t overflow. You can't compare by subtracting!
6347 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
6348 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
6350 * term.c: Include <sys/time.h>.
6351 (timeval_to_Time): New function, for proper overflow wraparound.

6359 (w32_get_internal_run_time):
6360 Port to higher-resolution Emacs time stamps.
6361 (ltime): Now accepts single 64-bit integer, as that's more convenient

6366 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
6367 for compatibility with pselect. Support ns-resolution time stamps.

6371 * xselect.c (wait_for_property_change, x_get_foreign_selection):
6372 Check for time stamp overflow, and support ns-resolution time stamps.
6374 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
6375 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
6376 (timeval_subtract): Remove; no longer needed.
6377 (XTflash, XTring_bell, x_wait_for_event):
6378 Port to ns-resolution time stamps. Don't assume time_t is signed.

6384 2012-06-22 Eli Zaretskii <eliz@gnu.org>
6386 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
6387 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
6388 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
6389 staticidx goes up to 1597 out of 1600 = 0x640.)
6391 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
6393 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
6394 Otherwise, the umask might be mistakenly 0 while handling input signals.
6396 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
6398 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

6404 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
6405 access to `contents' member of Lisp_Vector objects with AREF and ASET
6408 2012-06-19 Chong Yidong <cyd@gnu.org>
6410 * frame.c (delete_frame): When selecting a frame on a different
6411 text terminal, do not alter the terminal's top-frame.

6415 (unwind_format_mode_line): Restore them.
6416 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
6418 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
6419 since tty frames can be explicitly named.
6420 (prepare_menu_bars): Likewise.
6422 * term.c (Ftty_top_frame): New function.
6424 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
6426 Port byte-code-meter to modern targets.
6427 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
6428 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
6429 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
6430 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

6439 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
6440 gets killed during executing of this function (Bug#11665).
6441 Try to always return Qt when the buffer has been actually killed.
6442 (Vkill_buffer_query_functions): In doc-string say that functions
6443 run by this hook should not change the current buffer.
6445 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
6447 Fix recently-introduced process.c problems found by static checking.
6448 * process.c (write_queue_push, write_queue_pop, send_process):

6465 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
6467 * lisp.h (eassert): Assume C89 or later.
6468 This removes the need for CHECK.
6469 (CHECK): Remove. Its comments about always evaluating its
6470 argument were confusing, as 'eassert' typically does not evaluate
6473 * coding.c (produce_chars): Use ptrdiff_t, not int.
6475 * xterm.c (x_draw_underwave): Check for integer overflow.
6476 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

6780 Block-based vector allocation of small vectors.
6781 * lisp.h (struct vectorlike_header): New field `nbytes',
6782 adjust comment accordingly.
6783 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
6784 to denote vector blocks. Adjust users (live_vector_p,
6785 mark_maybe_pointer, valid_lisp_object_p) accordingly.
6786 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
6787 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
6788 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
6789 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),
6790 (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.
6791 (roundup_size): New constant.
6792 (struct vector_block): New data type.
6793 (vector_blocks, vector_free_lists, zero_vector): New variables.

6796 (sweep_vectors): New functions.
6797 (allocate_vectorlike): Return `zero_vector' as the only vector of
6798 0 items. Allocate new vector from block if vector size is less than

6800 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
6801 (init_alloc_once): Add call to init_vectors.

6805 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
6807 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
6809 * doprnt.c (doprnt): Truncate multibyte char correctly.
6810 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
6811 would mishandle a string argument "Xc" if X was a multibyte
6812 character of length 2: it would truncate after X's first byte
6813 rather than including all of X.
6815 2012-06-06 Chong Yidong <cyd@gnu.org>
6817 * buffer.c (word_wrap): Doc fix.
6819 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

6842 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
6843 (note_mode_line_or_margin_highlight): If there is no help echo,
6844 use mode-line-default-help-echo. Handle the case where the mouse
6845 position is past the end of the mode line string.
6847 * buffer.c (buffer_local_value_1): New function, split from
6848 Fbuffer_local_value; can return Qunbound.
6849 (Fbuffer_local_value): Use it.

6859 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
6860 and DEFVAR it. Update all users.
6862 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
6864 * minibuf.c (Fassoc_string): Remove duplicate declaration.
6866 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
6867 Convert pctcpu and pctmem to Lisp float properly.
6868 Let the compiler fold better, as 100.0/0x8000 is exact.
6870 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
6872 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
6875 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
6877 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
6879 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
6881 For a 'struct window', replace some Lisp_Object fields to
6882 bitfields where appropriate, remove unused fields.
6883 * window.h (struct window): Remove unused 'last_mark_x' and
6884 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
6885 change it's type from Lisp_Object to bitfield.
6886 Change type of 'force_start', 'optional_new_start',
6887 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
6888 fields from Lisp_Object to bitfield. Adjust users accordingly.
6890 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6892 Pacify gcc -Wdouble-precision when using Xaw.
6893 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
6894 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
6895 Use 'float' consistently, rather than 'float' in most places
6896 and 'double' in a couple of places.
6898 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6900 * xdisp.c (handle_stop): Detect whether we have overlay strings
6901 loaded by testing it->current.overlay_string_index to be
6902 non-negative, instead of checking whether n_overlay_strings is
6903 positive. (Bug#11587)
6905 2012-05-31 Chong Yidong <cyd@gnu.org>
6907 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
6909 * doc.c (Fsubstitute_command_keys): Doc fix.
6911 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6913 * search.c (search_buffer): Remove calls to
6914 r_alloc_inhibit_buffer_relocation, as it is now called by
6915 maybe_unify_char, which was the cause of relocation of buffer text
6918 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6920 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
6921 for the duration of call to load_charset, to avoid problems with
6922 callers of maybe_unify_char that access buffer text through C
6925 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
6926 decrement the inhibition flag, instead of just setting or
6929 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6931 Remove obsolete '#define static' cruft.
6932 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
6933 This #undef was "temporary" in 2000; it is no longer needed
6934 now that '#define static' has gone away.
6935 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
6936 (gray_bitmap_bits): Remove; no longer needed.
6937 All uses replaced with definiens.
6938 * xterm.c: Include "bitmaps/gray.xbm".
6940 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6942 Clean up __executable_start, monstartup when --enable-profiling.
6943 The following changes affect the code only when profiling.
6944 * dispnew.c (__executable_start): Rename from safe_bcopy.
6945 Define only on platforms that need it.
6946 * emacs.c: Include <sys/gmon.h> when profiling.
6947 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
6948 (__executable_start): Remove decl, since lisp.h does it now.
6949 (safe_bcopy): Remove decl; no longer has that name.
6950 (main): Coalesce #if into single bit of code, for simplicity.
6951 Cast pointers to uintptr_t, since standard libraries want integers
6953 * lisp.h (__executable_start): New decl.
6955 2012-05-31 Glenn Morris <rgm@gnu.org>
6957 * image.c (Fimagemagick_types): Doc fix.

6976 * lread.c (read1): Tiny simplification.
6978 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
6980 Do not create empty overlays with the evaporate property (Bug#9642).
6981 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
6982 Bug#9642, but explicitly check that the buffer the overlay would
6983 be moved to is live and rearrange lines to make sure that errors
6984 will not put the overlay in an inconsistent state.
6985 (Fdelete_overlay): Cosmetics.
6987 2012-05-28 Eli Zaretskii <eliz@gnu.org>
6989 * w32term.c (my_bring_window_to_top): New function.
6990 (x_raise_frame): Use handle returned by DeferWindowPos, which
6991 could be different from the original one.

6995 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
6996 by calling BringWindowToTop.
6998 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
6999 (WM_EMACS_END): Increase by one.
7001 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
7003 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
7004 This avoids undefined behavior that might cause the eassert
7005 to not catch an out-of-range value.
7007 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
7009 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

7019 when referring to sectname field in printf format.
7021 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
7023 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
7024 Only r_alloc_inhibit_buffer_relocation needed to be added;
7025 the others were already declared.
7027 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
7028 before checking whether it's out of range. Put the check inside
7030 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
7032 2012-05-27 Ken Brown <kbrown@cornell.edu>
7034 * callproc.c (Fcall_process): Restore a line that was accidentally
7035 commented out in the 2011-02-13 change (bug#11547).
7037 2012-05-27 Eli Zaretskii <eliz@gnu.org>
7039 * lisp.h [REL_ALLOC]: Add prototypes for external functions
7040 defined on ralloc.c.
7042 * buffer.c [REL_ALLOC]: Remove prototypes of
7043 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
7044 they are now on lisp.h.
7046 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
7048 * search.c (search_buffer): Use it to inhibit relocation of buffer
7049 text while re_search_2 is doing its job, because re_search_2 is
7050 passed C pointers to buffer text. (Bug#11519)
7052 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
7055 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
7056 state after an additional call to move_it_in_display_line_to, keep
7057 the values of it->max_ascent and it->max_descent found for the
7059 (pos_visible_p): Revert the comparison against bottom_y to what it
7060 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
7063 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
7065 Fix coding-related core dumps with gcc -ftrapv.
7066 The code was computing A - B, where A and B are pointers, and B is
7067 random garbage. This can lead to core dumps on platforms that
7068 have special pointer registers, and it also leads to core dumps on
7069 x86-64 when compiled with gcc -ftrapv. The fix is to compute
7070 A - B only when B is initialized properly.
7071 * coding.c (coding_set_source, coding_set_destination): Return void.
7072 (coding_change_source, coding_change_destinations): New functions,
7073 with the old behaviors of coding_set_source and coding_set_destination.
7074 All callers that need an offset changed to use these new functions.
7076 2012-05-26 Glenn Morris <rgm@gnu.org>
7078 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
7080 2012-05-26 Eli Zaretskii <eliz@gnu.org>

7083 * xdisp.c (draw_row_with_mouse_face):
7084 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
7086 * w32console.c: Include window.h.
7087 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
7089 (initialize_w32_display): Initialize mouse-highlight data.
7091 * w32inevt.c: Include termchar.h and window.h.
7092 (do_mouse_event): Support mouse-autoselect-window. When the mouse
7093 moves, call note_mouse_highlight. If help_echo changed, call
7094 gen_help_event to produce help-echo message in the echo area.
7095 Call clear_mouse_face if mouse_face_hidden is set in the mouse
7098 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
7100 * lread.c (read1): Simplify slightly to avoid an overflow warning
7101 with GCC 4.7.0 on x86-64.
7103 2012-05-26 Eli Zaretskii <eliz@gnu.org>
7105 * bidi.c (bidi_mirror_char): Revert last change: an int is
7106 definitely wide enough here.
7108 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
7110 Fix integer width and related bugs (Bug#9874).

7121 (allocate_pseudovector):
7122 Use int, not EMACS_INT, where int is wide enough.
7123 (inhibit_garbage_collection, Fgarbage_collect):
7124 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

7131 (bidi_level_of_next_char, bidi_move_to_visually_next):
7132 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

7137 (overlay_touches_p, struct sortvec, record_overlay_string)
7138 (overlay_strings, recenter_overlay_lists)
7139 (adjust_overlays_for_insert, adjust_overlays_for_delete)
7140 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
7141 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
7142 (Foverlay_recenter, last_overlay_modification_hooks_used)
7143 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
7144 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7145 (validate_region): Omit unnecessary test for b <= e,
7146 since that's guaranteed by the previous test.
7147 (adjust_overlays_for_delete): Avoid pos + length overflow.
7148 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
7149 (report_overlay_modification):
7150 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7151 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
7152 Omit pointer cast, which isn't needed anyway, and doesn't work
7153 after the EMACS_INT -> ptrdiff_t change.
7154 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
7155 * buffer.h: Adjust decls to match defn changes elsewhere.
7156 (struct buffer_text, struct buffer):
7157 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7158 Use EMACS_INT, not int, where int might not be wide enough.
7159 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
7160 not int, to avoid needless 32-bit limit on 64-bit hosts.
7161 (exec_byte_code): Use tighter memory-full test, one that checks
7162 for alloca overflow. Don't compute the address of the object just
7163 before an array, as that's not portable. Use EMACS_INT, not
7164 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
7165 * callint.c (Fcall_interactively):
7166 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7167 * callproc.c (call_process_kill, Fcall_process):
7168 Don't assume pid_t fits into an Emacs fixnum.

7177 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
7178 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7179 (casify_object): Avoid integer overflow when overallocating buffer.
7180 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
7181 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
7182 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
7183 * category.h (CATEGORYP): Don't assume arg is nonnegative.
7184 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
7185 integers are now checked earlier. All uses replaced with XINT.
7187 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7188 For CCL_MapSingle, check that content and value are in int range.

7190 Check that Vcode_version_map_vector is a vector.
7191 (resolve_symbol_ccl_program): Check that vector header is in range.
7192 Always copy the vector, so that we can check its contents reliably
7193 now rather than having to recheck each instruction as it's being
7194 executed. Check that vector words fit in 'int'.
7195 (ccl_get_compiled_code, Fregister_ccl_program)
7196 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
7197 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
7198 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
7199 contents are in range.
7200 (Fccl_execute_on_string): Check that status is in range.
7201 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
7202 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
7203 Accept and return EMACS_INT, not int, because callers can pass values
7205 (c_string_width, strwidth, lisp_string_width, chars_in_text)
7206 (multibyte_chars_in_text, parse_str_as_multibyte)
7207 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)

7209 (string_escape_byte8, Fget_byte):
7210 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

7931 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
7932 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
7934 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
7937 This directory predates autoconf and is no longer needed nowadays.
7938 Move its few remaining bits of functionality to where they're needed.
7939 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
7940 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
7941 * m/template.h: Remove.
7942 * Makefile.in (M_FILE): Remove. All uses removed.
7943 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
7944 * lisp.h (USE_LSB_TAG):
7945 * mem-limits.h (EXCEEDS_LISP_PTR):
7946 Use VAL_MAX, not VALBITS, in #if.
7947 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
7948 (EMACS_UINT): Define unconditionally now.
7949 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
7950 (BITS_PER_EMACS_INT): New constants, replacing
7951 what used to be in config.h, but not useful in #if.
7952 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
7953 define them any more.
7954 (VAL_MAX): New macro.
7956 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
7957 BITS_PER_EMACS_INT, in #if.
7958 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
7959 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
7960 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
7961 * s/ms-w32.h (DATA_START):
7962 Move here from removed file m/intel386.h.
7963 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
7964 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
7966 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
7968 Assume C89 or later.
7969 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
7970 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
7972 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
7973 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
7974 * textprop.c, tparam.c (NULL): Remove.
7975 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
7976 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
7977 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
7978 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
7979 * xterm.c (input_signal_count): Assume volatile works.
7981 2012-05-21 Ken Brown <kbrown@cornell.edu>
7983 * xgselect.c (xg_select): Fix first argument in call to 'select'
7986 2012-05-20 Ken Brown <kbrown@cornell.edu>
7988 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
7989 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
7991 2012-05-19 Ken Brown <kbrown@cornell.edu>
7993 * xfns.c (x_in_use): Remove `static' qualifier.
7994 * xterm.h (x_in_use): Declare.
7995 * xgselect.c: Include xterm.h.
7996 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
7997 and `display_arg' (bug#9754).
7999 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
8001 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
8003 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
8004 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
8006 2012-05-18 Eli Zaretskii <eliz@gnu.org>
8008 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
8010 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
8011 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
8013 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
8014 reference to image_cache->refcount.
8015 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
8017 2012-05-17 Juri Linkov <juri@jurta.org>
8019 * search.c (Fword_search_regexp, Fword_search_backward)
8020 (Fword_search_forward, Fword_search_backward_lax)
8021 (Fword_search_forward_lax): Move functions to isearch.el
8022 (bug#10145, bug#11381).
8024 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
8026 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
8028 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
8030 * lread.c (init_obarray): Declare Qt and Qnil as special.
8032 2012-05-14 Glenn Morris <rgm@gnu.org>
8034 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
8035 Put "libexec" before "bin", for the sake of init_callproc_1.
8037 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
8039 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
8041 * unexaix.c: Port to more-recent AIX compilers.
8042 (report_error, report_error_1, make_hdr, copy_sym)
8043 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
8044 Make arguments const char *, not char *, to avoid violations of C
8045 standard and to fix some AIX warnings reported by Gilles Pion.
8047 2012-05-14 Eli Zaretskii <eliz@gnu.org>
8049 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
8050 already have overlays loaded.
8051 (handle_single_display_spec): Before returning without displaying
8052 fringe bitmap, synchronize the bidi iterator with the main display
8053 iterator, by calling iterate_out_of_display_property.
8054 (iterate_out_of_display_property): Detect buffer iteration by
8055 testing that it->string is a Lisp string.
8056 (get_next_display_element): When the current object is exhausted,
8057 and there's something on it->stack, call set_iterator_to_next to
8058 proceed with what's on the stack, instead of returning zero.
8059 (set_iterator_to_next): If called at the end of a Lisp string,
8060 proceed to consider_string_end without incrementing string
8061 position. Don't increment display vector index past the end of
8062 the display vector. (Bug#11417)
8063 (pos_visible_p): Don't report a position visible when move_it_to
8064 stopped at the last line of window, which happens to be scanned
8065 backwards by the bidi iteration. (Bug#11464)
8067 2012-05-14 Eli Zaretskii <eliz@gnu.org>
8069 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
8070 and right-margin display specs even if the spec is invalid or we
8071 are on a TTY, and thus unable to display on the fringes.
8072 That's because the text with the property will not be displayed anyway,
8073 so we need to signal to the caller that this is a "replacing"
8074 display spec. This fixes display when the spec is invalid or we
8077 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
8079 * unexaix.c (make_hdr): Fix typo in prototype.
8080 This bug broke the build on AIX. Problem reported by Gilles Pion.
8082 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
8084 * keyboard.c (kbd_buffer_get_event): Read special events also in
8085 batch mode. (Bug#11415)
8087 2012-05-12 Glenn Morris <rgm@gnu.org>
8089 * ns.mk: Update for ns_appbindir no longer having trailing "/".
8091 2012-05-12 Eli Zaretskii <eliz@gnu.org>
8093 * lisp.mk (lisp): Add newcomment.elc.
8095 2012-05-12 Glenn Morris <rgm@gnu.org>
8097 * Makefile.in (MKDIR_P): New, set by configure.
8098 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
8100 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
8102 Remove unused function hourglass_started.
8103 * dispextern.h (hourglass_started):
8104 * w32fns.c (hourglass_started):
8105 * xdisp.c (hourglass_started): Remove.
8107 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
8109 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
8110 Update dependencies.
8112 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
8114 * xgselect.c (xg_select): Put maxfds+1 into a var.
8115 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
8117 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
8119 2012-05-10 Dave Abrahams <dave@boostpro.com>
8121 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
8122 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
8124 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
8126 * dbusbind.c (xd_registered_buses): New internal Lisp object.
8127 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
8128 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
8129 Initialize xd_registered_buses.
8131 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
8133 Untag more efficiently if USE_LSB_TAG.
8134 This is based on a proposal by YAMAMOTO Mitsuharu in
8135 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
8136 For an admittedly artificial (nth 8000 longlist) benchmark on
8137 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
8138 Emacs's overall text size by 1%.
8139 * lisp.h (XUNTAG): New macro.
8140 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
8141 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
8142 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
8143 * eval.c (Fautoload):
8144 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
8145 * frame.h (XFRAME): Use XUNTAG.
8147 Port recent dbusbind.c changes to 32-bit --with-wide-int.
8148 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
8149 Remove unportable assumptions about print widths of types like
8151 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
8152 intptr_t when converting between pointer and integer, to avoid GCC
8153 warnings about wrong width.
8155 2012-05-09 Eli Zaretskii <eliz@gnu.org>
8157 * w32proc.c (new_child): Force Windows to reserve only 64KB of
8158 stack for each reader_thread, instead of defaulting to 8MB
8159 determined by the linker. This avoids failures in creating
8160 subprocesses on Windows 7, see the discussion in this thread:
8161 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
8163 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
8165 Fix up display of the *Minibuf-0* buffer in the mini window.
8166 * keyboard.c (read_char): Don't clear the echo area if there's no
8168 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
8169 contents of *Minibuf-0*) if there's no message displayed in its stead.
8171 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
8173 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
8176 2012-05-06 Chong Yidong <cyd@gnu.org>
8178 * lisp.mk (lisp): Update.
8180 2012-05-05 Jim Meyering <meyering@redhat.com>
8182 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
8184 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
8186 * data.c (PUT_ERROR): New macro.
8187 (syms_of_data): Use it. Add new error type `user-error'.
8188 * undo.c (user_error): New function.
8189 (Fprimitive_undo): Use it.
8190 * print.c (print_error_message): Adjust print style for `user-error'.
8191 * keyboard.c (user_error): New function.
8192 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
8194 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
8196 Do not limit current-time-string to years 1000..9999.
8197 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
8198 (Fcurrent_time_string): Support any year that is supported by the
8199 underlying localtime representation. Don't use asctime, as it
8200 has undefined behavior for years outside the range -999..9999.
8202 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
8204 Fix race conditions involving setenv, gmtime, localtime, asctime.
8205 Without this fix, interrupts could mess up code that uses these
8206 nonreentrant functions, since setting TZ invalidates existing
8207 tm_zone or tzname values, and since most of these functions return
8208 pointers to static storage.
8209 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
8210 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
8211 Grow the critical sections to include not just invoking
8212 localtime/gmtime, but also accessing these functions' results
8213 including their tm_zone values if any, and any related TZ setting.
8214 (format_time_string): Last arg is now struct tm *, not struct tm **,
8215 so that the struct tm is saved in the critical section.
8216 All callers changed. Simplify allocation of initial buffer, partly
8217 motivated by the fact that memory allocation needs to be outside
8218 the critical section.
8220 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
8222 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
8223 with RESET_INTERVAL.
8225 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
8226 Remove duplicated buffer name initialization.
8228 2012-05-02 Jim Meyering <jim@meyering.net>
8230 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
8232 * xfns.c (x_window): Use xstrdup (Bug#11375).
8234 2012-05-02 Eli Zaretskii <eliz@gnu.org>
8236 * xdisp.c (pos_visible_p): If already at a newline from the
8237 display string before the 'while' loop, don't walk back the glyphs
8238 from it3.glyph_row. Solves assertion violation when the display
8239 string begins with a newline (egg.el). (Bug#11367)
8241 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
8243 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
8246 2012-05-01 Glenn Morris <rgm@gnu.org>
8248 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
8249 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
8250 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
8251 All were removed before 23.1.
8253 * dispnew.c: Remove HAVE_LIBNCURSES test;
8254 it is always true on relevant platforms.
8256 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
8257 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
8259 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
8261 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
8263 * .gdbinit (xpr): Remove checks for no longer existing misc types.
8264 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
8267 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
8269 Do not avoid creating empty evaporating overlays (Bug#9642).
8270 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
8271 That is, do not delete an evaporating overlay if it becomes
8272 empty after its bounds are adjusted to fit within its buffer.
8273 This fix caused other problems, and I'm reverting it until we get
8274 to the bottom of them.
8276 2012-04-27 Chong Yidong <cyd@gnu.org>
8278 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
8280 2012-04-27 Eli Zaretskii <eliz@gnu.org>
8282 * xdisp.c (pos_visible_p): If the window start position is beyond
8283 ZV, start the display from buffer beginning. Prevents assertion
8284 violation in init_iterator when the minibuffer window is scrolled
8287 * window.c (window_scroll_pixel_based): Likewise.
8289 2012-04-27 Chong Yidong <cyd@gnu.org>
8291 * keymap.c (where_is_internal): Doc fix (Bug#10872).
8293 2012-04-27 Glenn Morris <rgm@gnu.org>
8295 * fileio.c (Fcopy_file, Fset_file_selinux_context):
8296 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
8298 2012-04-27 Eli Zaretskii <eliz@gnu.org>
8300 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
8301 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
8303 2012-04-26 Eli Zaretskii <eliz@gnu.org>
8305 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
8306 display element, check also the underlying string or buffer
8307 character. (Bug#11341)
8309 * w32menu.c: Include w32heap.h.
8310 (add_menu_item): If the call to AppendMenuW (via
8311 unicode_append_menu) fails, disable Unicode menus only if we are
8312 running on Windows 9X/Me.
8314 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
8316 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
8317 (xgetint): Add missing shift for LSB tags.
8319 2012-04-24 Martin Rudalics <rudalics@gmx.at>
8321 * keyboard.c (read_char): Don't wipe echo area for select window
8322 events: These might get delayed via `mouse-autoselect-window'
8325 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
8327 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
8328 manipulation of :loaded-from data.
8330 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
8332 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
8333 now a cons (bug#11311).
8335 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
8337 Do not create empty overlays with the evaporate property (Bug#9642).
8338 * buffer.c (Fmove_overlay): Delete an evaporating overlay
8339 if it becomes empty after its bounds are adjusted to fit within
8340 its buffer. Without this fix, in a nonempty buffer (let ((o
8341 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
8342 yields an empty overlay that has the evaporate property, which is
8343 not supposed to happen.
8345 Fix minor GTK3 problems found by static checking.
8346 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
8347 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
8348 (struct _EmacsFixedClass, emacs_fixed_get_type):
8349 Move decls here from emacsgtkfixed.h, since they needn't be public.
8350 (emacs_fixed_get_type): Now static.
8351 (emacs_fixed_class_init): Omit unused local.
8352 (emacs_fixed_child_type): Remove; unused.
8353 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
8354 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
8355 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
8356 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
8357 (EMACS_FIXED_GET_CLASS): Remove; unused.
8358 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
8360 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
8361 Problem reported by Juanma Barranquero for Windows -Wunused-function.
8363 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
8365 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
8366 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
8367 (__malloc_size_t, __malloc_ptrdiff_t):
8368 Remove. All uses removed, replaced by the definiens if needed,
8369 since we can assume C89 or better now.
8370 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
8371 (protect_malloc_state, align, get_contiguous_space)

8447 since the two debugging options are incompatible.
8448 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
8450 (mem_init, mem_insert, mem_insert_fixup):
8451 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

8546 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
8547 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

8617 2012-04-11 Daniel Colascione <dancol@dancol.org>
8619 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
8620 against is gone. It's better to use vfork now so that when Cygwin
8621 gains a new, working vfork, we use it automatically (bug#10398).
8623 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

8678 2012-04-09 Eli Zaretskii <eliz@gnu.org>
8680 * xdisp.c (set_cursor_from_row): If the display string appears in
8681 the buffer at position that is closer to point than the position
8682 after the display string, display the cursor on the first glyph of
8683 the display string. Fixes cursor display when a 'display' text
8684 property immediately follows invisible text. (Bug#11094)
8686 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
8688 composite.c: use 'double' consistently
8689 * composite.c (get_composition_id): Use 'double' consistently
8690 instead of converting 'float' to 'double' and vice versa; this is
8691 easier to understand and avoids a GCC warning.

8740 [!WINDOWSNT]: New macros.
8741 (init_libxml2_functions, libxml2_loaded_p): New functions.
8742 (parse_region): Call fn_xmlCheckVersion instead of using the macro

8765 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
8766 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
8767 about subtle differences between FETCH_CHAR* and STRING_CHAR*
8768 macros related to unification of CJK characters. For the details,
8769 see the discussion following the message here:
8770 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
8772 2012-04-04 Chong Yidong <cyd@gnu.org>

8788 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
8789 position we get to after a call to move_it_to fails the
8790 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
8791 only if we wind up in a string from display property. (Bug#11063)
8793 * window.c (Fdelete_other_windows_internal): Invalidate the row
8794 and column information about mouse highlight, so that redisplay
8795 restores it after reallocating the glyph matrices. (Bug#7464)
8797 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
8798 string comes from a `display' text property, use the buffer
8799 position of that property as if we actually saw that position in
8801 (move_it_by_lines): Remove the assertion that
8802 "it->current_x == 0 && it->hpos == 0" which can be legitimately
8803 violated when there's a before-string at the beginning of a line.
8806 2012-03-30 Eli Zaretskii <eliz@gnu.org>

8841 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
8843 2012-03-25 Kenichi Handa <handa@m17n.org>
8845 * dispextern.h (struct glyph): Change the bit length of
8846 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
8848 2012-03-24 Eli Zaretskii <eliz@gnu.org>
8850 * s/ms-w32.h (tzname): Include time.h before redirecting to
8851 _tzname. Fixes the MSVC build. (Bug#9960)

8855 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
8858 * xterm.c (XTread_socket): Only modify handling_signal if
8859 !SYNC_INPUT. (Bug#11080)
8861 2012-03-23 Eli Zaretskii <eliz@gnu.org>
8863 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
8864 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
8865 when fetching a multibyte character consumes more bytes than
8866 CHAR_BYTES returns, due to unification of CJK characters in
8867 string_char. (Bug#11073)
8869 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
8871 * process.c (wait_reading_process_output): Handle pty disconnect
8872 by refraining from sending oneself a SIGCHLD (bug#10933).
8874 2012-03-22 Chong Yidong <cyd@gnu.org>

8887 2012-03-20 Eli Zaretskii <eliz@gnu.org>
8889 * w32proc.c (Fw32_set_console_codepage)
8890 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
8893 2012-03-20 Chong Yidong <cyd@gnu.org>
8895 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
8896 to reflect default non-nil value of redisplay-dont-pause.
8898 2012-03-19 Kenichi Handa <handa@m17n.org>
8900 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
8901 it fit in a valid range (Bug#11003).
8903 2012-03-18 Eli Zaretskii <eliz@gnu.org>
8905 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
8906 that is not from display property, accept the row as a "cursor
8907 row" if one of the string's character has a non-nil `cursor'
8908 property. Fixes cursor positioning when there are newlines in
8909 overlay strings, e.g. in icomplete.el. (Bug#11035)
8911 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
8913 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
8915 2012-03-12 Chong Yidong <cyd@gnu.org>
8917 * eval.c (inhibit_lisp_code): Rename from
8918 inhibit_window_configuration_change_hook; move from window.c.
8920 * xfns.c (unwind_create_frame_1, Fx_create_frame):
8921 * window.c (run_window_configuration_change_hook)
8922 (syms_of_window): Callers changed.
8924 2012-03-11 Chong Yidong <cyd@gnu.org>

8933 is visible (Bug#10955).
8935 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
8937 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
8939 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
8941 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
8942 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
8945 2012-03-03 Glenn Morris <rgm@gnu.org>
8947 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
8949 2012-03-02 Eli Zaretskii <eliz@gnu.org>
8951 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
8952 position past the first glyph_row that ends at ZV. (Bug#10902)
8953 (redisplay_window, next_element_from_string): Fix typos in
8955 (redisplay_window): Pass to move_it_vertically the margin in
8956 pixels, not in screen lines.
8958 2012-03-02 Glenn Morris <rgm@gnu.org>
8960 * buffer.c (buffer-list-update-hook): Doc fix.
8962 2012-02-29 Eli Zaretskii <eliz@gnu.org>
8964 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
8965 push_it before setting up the iterator for the first overlay
8966 string, even if we have an empty string loaded.
8967 (next_overlay_string): If there's an empty string on the iterator
8968 stack, pop the stack. (Bug#10903)
8970 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
8972 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
8973 Suggested by Stefan Monnier in
8974 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
8975 * alloc.c (widen_to_Lisp_Object): New static function.
8976 (mark_memory): Also mark Lisp_Objects by fetching pointer words
8977 and widening them to Lisp_Objects. This would work even if
8978 USE_LSB_TAG is defined and wide integers are used, which might
8979 happen in a future version of Emacs.
8981 2012-02-25 Chong Yidong <cyd@gnu.org>
8983 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
8986 * xselect.c (Fx_selection_exists_p): Doc fix.
8987 (x_clipboard_manager_save_all): Print an informative message
8988 before saving to clipboard manager.
8990 2012-02-24 Chong Yidong <cyd@gnu.org>
8992 * keyboard.c (process_special_events): Handle all X selection
8993 requests in kbd_buffer, not just the next one (Bug#8869).
8995 2012-02-23 Chong Yidong <cyd@gnu.org>
8997 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
8998 call when setting menu-bar-lines and tool-bar-lines parameters.
8999 (unwind_create_frame_1): New helper function.
9001 * window.c (inhibit_window_configuration_change_hook): New var.
9002 (run_window_configuration_change_hook): Obey it.
9003 (syms_of_window): Initialize it.
9005 2012-02-22 Chong Yidong <cyd@gnu.org>
9007 * xterm.c (x_draw_image_relief): Add missing type check for
9008 Vtool_bar_button_margin (Bug#10743).

9012 * fileio.c (Vfile_name_handler_alist): Doc fix.
9014 * buffer.c (Fget_file_buffer): Protect against invalid file
9015 handler return value.
9017 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
9019 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
9020 when computing $valmask.
9022 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
9023 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
9024 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
9025 It's useless in that case, and it can cause problems on hosts
9026 that allocate halves of EMACS_INT values separately.
9027 Reported by Dan Horák. Diagnosed by Andreas Schwab in
9028 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
9029 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
9030 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
9031 it avoids undefined behavior on hosts where shifting right by more
9032 than the word width has undefined behavior.
9034 2012-02-19 Chong Yidong <cyd@gnu.org>
9036 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
9037 (Funhandled_file_name_directory, Ffile_name_as_directory)
9038 (Fdirectory_file_name, Fexpand_file_name)

9054 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
9056 2012-02-15 Chong Yidong <cyd@gnu.org>
9058 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
9059 marked as special. Also, starting docstrings with * is obsolete.
9061 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
9063 * gnutls.c (emacs_gnutls_write): Fix last change.
9065 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

9074 2012-02-12 Chong Yidong <cyd@gnu.org>
9076 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
9077 as that creates a dangerous corner case.
9079 * window.c (Fdelete_window_internal): Invalidate the mouse
9080 highlight (Bug#9904).
9082 2012-02-12 Glenn Morris <rgm@gnu.org>

9087 * nsselect.m (Fx_own_selection_internal)
9088 (Fx_disown_selection_internal, Fx_selection_exists_p)
9089 (Fx_selection_owner_p, Fx_get_selection_internal):
9090 Sync docs and argument specs with the xselect.c versions.
9092 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
9094 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

9112 2012-02-07 Chong Yidong <cyd@gnu.org>
9114 * buffer.c (Fbuffer_local_variables)
9115 (buffer_lisp_local_variables): Handle unbound vars correctly;
9116 don't let Qunbound leak into Lisp.
9118 2012-02-07 Glenn Morris <rgm@gnu.org>
9120 * image.c (Fimagemagick_types): Doc fix.
9122 * image.c (imagemagick-render-type): Change it from a lisp object
9123 to an integer. Move the doc here from the lisp manual.

9126 2012-02-06 Chong Yidong <cyd@gnu.org>
9128 * doc.c (store_function_docstring): Avoid applying docstring of
9129 alias to base function (Bug#2603).
9131 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
9133 * .gdbinit (pp1, pv1): Remove redundant defines.
9136 2012-02-04 Chong Yidong <cyd@gnu.org>
9138 * nsterm.m: Declare a global (Bug#10694).

9153 before BEGV. (Bug#10696)
9155 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
9157 Handle overflow when computing char display width (Bug#9496).
9158 * character.c (char_width): Return EMACS_INT, not int.
9159 (char_width, c_string_width): Check for overflow when
9160 computing the width; this is possible now that individual
9161 characters can have unbounded width. Problem introduced
9162 by merge from Emacs 23 on 2012-01-19.
9164 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
9166 * dbusbind.c (Fdbus_register_method): Mention the return value

9179 2012-02-02 Kenichi Handa <handa@m17n.org>
9181 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
9182 0, do not call append_composite_glyph.

9186 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
9188 (x_produce_glyphs): If the component of a composition is a null
9189 string, set it->pixel_width to 1 to avoid zero-width glyph.

9193 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
9194 first 2 arguments are identical. This makes inserting large
9195 output from a subprocess an order of magnitude faster on
9196 MS-Windows, where all sbrk'ed memory is always contiguous.
9198 2012-01-31 Glenn Morris <rgm@gnu.org>

9239 since nil is not allowed anyway.
9241 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
9243 * process.c (read_process_output): Use p instead of XPROCESS (proc).

9254 * character.c (char_width): New function.
9255 (Fchar_width, c_string_width, lisp_string_width):
9256 Use char_width (Bug#9496).

9260 * window.c (Vwindow_persistent_parameters): New variable.
9261 (Fset_window_configuration, save_window_save): Handle persistent
9264 2012-01-14 Eli Zaretskii <eliz@gnu.org>
9266 * w32fns.c (signal_user_input): Don't do a QUIT, to avoid
9267 thrashing the stack of the thread. (Bug#9087)

9278 he end column for display of highlight that ends on a newline
9281 2012-01-11 Glenn Morris <rgm@gnu.org>
9283 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
9284 from load-path also when installation-directory is nil. (Bug#10208)
9286 2012-01-10 Glenn Morris <rgm@gnu.org>
9288 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.

9291 Update template values to be closer to their typical values these days.
9293 2012-01-09 Eli Zaretskii <eliz@gnu.org>
9295 * xdisp.c (rows_from_pos_range): Accept additional argument
9296 DISP_STRING, and accept any glyph in a row whose object is that
9297 string as eligible for mouse highlight. Fixes mouse highlight of
9298 display strings from overlays. (Bug#10464)
9300 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
9302 emacs: fix an auto-save permissions race condition (Bug#10400)
9303 * fileio.c (auto_saving_dir_umask): New static var.
9304 (Fmake_directory_internal): Use it.
9305 (do_auto_save_make_dir): Set it, instead of invoking chmod after
9306 creating the directory. The old code temporarily assigns
9307 too-generous permissions to the directory.
9308 (do_auto_save_eh): Clear it.
9309 (Fdo_auto_save): Catch all errors, not just file errors, so
9310 that the var is always cleared.
9312 2012-01-07 Eli Zaretskii <eliz@gnu.org>
9314 * search.c (scan_buffer): Pass character positions to
9315 know_region_cache, not byte positions. (Bug#6540)
9317 2012-01-07 LynX <_LynX@bk.ru> (tiny change)
9319 * w32.c (sys_rename): Report EXDEV when rename of a directory

9813 Problem reported by Andreas Schwab in
9814 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
9815 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
9816 is set, removing the need for VIRT_ADDRESS_VARIES.
9817 (PURE_P): Use a more-efficient implementation that needs just one
9818 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the

9820 to 4 (xorl, subq, cmpq, setbe).

9825 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

10297 (g_b_init_get_glyph_outline_w): New static variables.
10298 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
10299 (GetGlyphOutlineW_Proc): New typedefs.
10300 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
10301 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
10303 (w32font_open_internal, compute_metrics):
10304 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
10305 instead of calling the "wide" APIs directly.
10307 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
10309 * w32.h (syms_of_w32font): Add prototype.
10311 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
10313 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
10314 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
10315 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
10316 (Fmove_to_window_line): Doc fix.
10318 2011-10-27 Chong Yidong <cyd@gnu.org>
10320 * process.c (make_process): Set gnutls_state to NULL.
10322 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
10323 non-NULL, regardless of GNUTLS_INITSTAGE.
10324 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
10325 an error. Set process slots as soon as we allocate them.
10327 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
10329 2011-10-27 Chong Yidong <cyd@gnu.org>
10331 * gnutls.c (emacs_gnutls_deinit): New function.
10332 Deallocate credentials structures as well as calling gnutls_deinit.
10333 (Fgnutls_deinit, Fgnutls_boot): Use it.
10335 * process.c (make_process): Initialize GnuTLS credentials to NULL.
10336 (deactivate_process): Call emacs_gnutls_deinit.
10338 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
10340 * image.c (x_create_x_image_and_pixmap):
10341 * w32.c (sys_rename, w32_delayed_load):
10342 * w32font.c (fill_in_logfont):
10343 * w32reg.c (x_get_string_resource): Silence compiler warnings.
10345 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
10347 * w32fns.c (w32_default_color_map): New function,
10348 extracted from Fw32_default_color_map.
10349 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
10351 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
10353 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
10355 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
10357 * keyboard.c (test_undefined): New function (bug#9751).
10358 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
10360 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
10362 * sysdep.c (init_sys_modes): Fix the check for the controlling
10363 terminal (Bug#6649).
10365 2011-10-20 Eli Zaretskii <eliz@gnu.org>
10367 * dispextern.h (struct bidi_it): New member next_en_type.
10369 * bidi.c (bidi_line_init): Initialize the next_en_type member.
10370 (bidi_resolve_explicit_1): When next_en_pos is valid for the
10371 current character, check also for next_en_type being WEAK_EN.
10372 (bidi_resolve_weak): Don't enter the expensive loop if the current
10373 position is before next_en_pos. Record the bidi type of the first
10374 non-ET, non-BN character we find, in addition to its position.
10375 (bidi_level_of_next_char): Invalidate next_en_type when
10376 next_en_pos is over-stepped.
10378 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
10380 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
10381 * editfns.c: Rewrite current-time-zone so that it invokes
10382 the equivalent of (format-time-string "%Z") to get the time zone name.
10383 This fixes a bug when the time zone name contains characters that
10384 need converting from the system time locale to Emacs internal format.
10385 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
10386 that patch fixed format-time-string to do the conversion, but
10387 I forgot to fix current-time-zone.
10388 (format_time_string): New function, containing most of
10389 what Fformat_time_string used to contain.
10390 (Fformat_time_string): Rewrite in terms of format_time_string.
10391 This doesn't change this function's behavior.
10392 (current-time-zone): Rewrite to use format_time_string.
10393 This fixes the bug reported by Michael Schierl in
10394 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
10395 Jason Rumney's 2007-06-07 change worked around this bug, but
10397 * systime.h (tzname, timezone): Remove no-longer-used declarations.
10399 2011-10-19 Eli Zaretskii <eliz@gnu.org>
10401 * xdisp.c (start_display): If the character at POS is displayed
10402 via a display vector, reset IT->current.dpvec_index to zero.
10403 (try_window_reusing_current_matrix): If a line ends in a display
10404 vector or the next line starts in a display vector, continue
10405 redrawing the window even though the character position of
10406 start_row was reached.
10409 2011-10-18 Chong Yidong <cyd@gnu.org>
10411 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
10412 with nobreak-char-display too.
10414 2011-10-18 Eli Zaretskii <eliz@gnu.org>
10416 Fix part 3 of bug#9771.
10417 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
10418 (bidi_resolve_neutral): Don't enter the expensive loop looking for
10419 non-neutral characters if the current character is a paragraph
10420 separator (a.k.a. Newline). This avoids running the same
10421 expensive loop twice, once when we consume the preceding newline
10422 and the other time when the line actually needs to be displayed.
10423 Avoid the loop when we see neutrals on the base embedding level
10424 following a character whose directionality is the same as the
10425 paragraph's. This avoids running the expensive loop when a line
10426 ends in a long sequence of neutrals, like control characters.
10427 Add assertion against STRONG_AL type. Slightly rearrange code
10428 that determines the type of a neutral given the first non-neutral
10430 (bidi_level_of_next_char): Set next_en_pos to zero when
10431 invalidating its info.
10433 2011-10-17 Eli Zaretskii <eliz@gnu.org>
10435 * xdisp.c (push_display_prop): Determine whether to record string
10436 or buffer position by IT->string, not by IT->method. Allow
10437 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
10438 (move_it_vertically_backward): Don't look for character position
10439 immediately after the newline when in a continuation line.
10442 2011-10-15 Martin Rudalics <rudalics@gmx.at>
10444 * window.c (coordinates_in_window): Rewrite and delabelize
10445 vertical border check. (Bug#5357) (Bug#9618)
10447 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
10449 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
10450 errors in XSetWindowBorder (bug#9310).
10452 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
10454 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
10455 avoid crash when xmalloc overrun checking is enabled.
10457 2011-10-13 Eli Zaretskii <eliz@gnu.org>
10459 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
10460 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
10461 cursor motion with <left> and <right> arrow keys.
10463 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
10464 some callers set that themselves.
10466 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10468 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
10469 display string and the previous row comes from the same string and
10470 is empty. (Bug#9739) (Bug#9738)
10472 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
10474 * doc.c (get_doc_string): Encode file name (bug#9735).
10476 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10478 * bidi.c (bidi_level_of_next_char):
10479 * xdisp.c (get_visually_first_element): Remove old incorrect
10480 comments regarding the Unicode Line Separator character.
10482 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
10484 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
10486 * alloc.c (Fgc_status): Do not access beyond zombies array
10487 boundary if nzombies > MAX_ZOMBIES.
10488 * alloc.c (dump_zombies): Add missing format specifier.
10490 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
10492 * xdisp.c (set_cursor_from_row): Simplify conditionals,
10493 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
10495 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
10496 Some packages use them to denote characters with modifiers.
10498 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
10500 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
10501 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
10502 matching a pp-number. Rename parameter var to var1.
10504 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
10506 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
10508 2011-10-08 Glenn Morris <rgm@gnu.org>
10510 * callint.c (Fcall_interactively): Give a more explicit error for the
10511 'c' case with a non-character input. (Bug#8479)
10513 2011-10-08 Eli Zaretskii <eliz@gnu.org>
10515 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
10517 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
10518 lines that are hscrolled on the left.
10520 * dispnew.c (buffer_posn_from_coords): Account for a possible
10521 presence of header-line. (Bug#4426)
10523 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
10525 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
10526 Don't advertise functionality which we discourage or doesn't work.
10528 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
10530 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
10531 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
10532 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
10533 this makes Emacs dump core during garbage collection on rare
10534 occasions. sizeof is obviously inferior to offsetof here, so
10535 stick with offsetof.
10536 (GC_POINTER_ALIGNMENT): New macro.
10537 (mark_memory): Omit 3rd (offset) arg; caller changed.
10538 Don't assume EMACS_INT alignment is the same as pointer alignment.
10540 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
10542 * keyboard.c (read_key_sequence_remapped): New var.
10543 (read_key_sequence): Compute remapping in the right buffer.
10544 (command_loop_1): Use read_key_sequence's remapping directly.
10546 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
10548 * dired.c (file_name_completion): Don't expand file name.
10549 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
10550 before checking file name handler.
10552 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
10553 they've been requested explicitly (bug#9591).
10555 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
10557 * keymap.c (Fsingle_key_description): Use make_specified_string
10558 instead of build_string to build string from push_key_description.
10561 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10563 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
10564 This fixes a Y2038 bug on 64-bit hosts.
10565 * buffer.c (reset_buffer):
10566 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
10567 (Fclear_buffer_auto_save_failure):
10568 Use 0, not -1, to represent an unset failure time, since time_t
10569 might not be signed.
10571 Remove dependency on glibc malloc internals.
10572 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10573 Move back here from lisp.h, but with their new implementations.
10574 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10575 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
10576 * charset.c (charset_table_init): New static var.
10577 (syms_of_charset): Use it instead of xmalloc. This removes a
10578 dependency on glibc malloc internals. See Eli Zaretskii's comment in
10579 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
10580 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10581 Move back to alloc.c.
10582 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10583 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
10585 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
10587 * nsterm.m (windowDidResize): Call x_set_window_size only when
10588 ns_in_resize is true. Otherwise set pixelwidth/height and
10589 call change_frame_size (Bug#9628).
10591 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10593 Port --enable-checking=all to Fedora 14 x86-64.
10594 * charset.c (syms_of_charset): Also account for glibc malloc's
10595 internal overhead when calculating the initial malloc maximum.
10597 Port --enable-checking=all to Fedora 14 x86.
10598 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10600 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
10601 (overrun_check_realloc, overrun_check_free):
10602 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
10603 That way, xmalloc returns a properly-aligned pointer even if
10604 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
10605 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
10606 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
10607 into account when calculating the initial malloc maximum.
10608 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10609 Move here from alloc.c, so that charset.c can use it too.
10610 Properly align; the old code wasn't right for common 32-bit hosts
10611 when configured with --enable-checking=all.
10612 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10613 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
10615 2011-09-29 Eli Zaretskii <eliz@gnu.org>
10617 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
10620 2011-09-28 Eli Zaretskii <eliz@gnu.org>
10622 * xdisp.c (compute_display_string_end): If there's no display
10623 string at CHARPOS, return -1.
10625 * bidi.c (bidi_fetch_char): When compute_display_string_end
10626 returns a negative value, treat the character as a normal
10627 character not covered by a display string. (Bug#9624)
10629 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
10631 * lread.c (Fread_from_string): Fix typo in docstring.
10633 2011-09-27 Eli Zaretskii <eliz@gnu.org>
10635 * xdisp.c (handle_invisible_prop): If invisible text ends on a
10636 newline, reseat the iterator instead of bidi-iterating there one
10637 character at a time. (Bug#9610)
10638 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
10639 TO_CHARPOS if the bidi iterator is at base embedding level.
10641 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
10643 * lread.c (readevalloop): Use correct code for NBSP.
10644 (read1): Likewise. (Bug#9608)
10646 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
10648 * dbusbind.c (Fdbus_register_signal): When service is not
10649 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
10651 2011-09-25 Glenn Morris <rgm@gnu.org>
10653 * buffer.c (truncate-lines): Doc fix.
10655 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
10657 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
10658 (Fset_window_next_buffers): Doc fix.
10660 2011-09-24 Glenn Morris <rgm@gnu.org>
10662 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
10664 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
10666 Fix minor problems found by static checking.
10667 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
10668 * indent.c (Fvertical_motion): Fix == vs = typo.
10670 2011-09-24 Eli Zaretskii <eliz@gnu.org>
10672 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
10673 Default value is now t. Doc fix.
10675 * indent.c (Fvertical_motion): Compute and apply the overshoot
10676 logic when moving up, not only when moving down. Fix the
10677 confusing name and values of the it_overshoot_expected variable;
10678 logic changes accordingly. (Bug#9254) (Bug#9549)
10680 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
10681 CHARPOS is covered by a display string which includes newlines.
10682 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
10683 is covered by a display string with embedded newlines.
10685 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
10687 * dbusbind.c (Fdbus_register_signal): Add match rule to
10688 Vdbus_registered_objects_table. (Bug#9581)
10689 (Fdbus_register_method, Vdbus_registered_objects_table):
10692 2011-09-24 Jim Meyering <meyering@redhat.com>
10694 do not ignore write error for any output size
10695 The previous change was incomplete.
10696 While it makes emacs --batch detect the vast majority of stdout
10697 write failures, errors were still ignored whenever the output size is
10698 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
10699 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
10700 && echo FAIL: ignored write error
10701 FAIL: ignored write error
10702 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
10703 && echo FAIL: ignored write error
10704 FAIL: ignored write error
10705 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
10707 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
10709 * emacs.c (Fkill_emacs): In noninteractive mode exit
10710 non-successfully if a write error occurred on stdout. (Bug#9574)
10712 2011-09-21 Eli Zaretskii <eliz@gnu.org>
10714 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
10717 * dispextern.h (struct it): Update the comment documenting what
10720 2011-09-20 Eli Zaretskii <eliz@gnu.org>
10722 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
10723 a display string, extend search for cursor position to end of row.
10724 (find_row_edges): If the row ends in a newline from a display
10725 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
10726 Handle the case of a display string with multiple newlines.
10727 (Fcurrent_bidi_paragraph_direction): Fix search for previous
10728 non-empty line. Fixes confusing cursor motion with arrow keys at
10729 the beginning of a line that starts with whitespace.
10731 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
10733 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
10736 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
10738 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
10739 boolean (Bug#9154).
10741 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10743 * xdisp.c (display_line): Record maximum and minimum buffer
10744 positions even if no glyphs were produced (e.g., by a zero-width
10745 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
10746 buffer positions that will be removed from the glyph row because
10748 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
10749 column is beyond frame width: don't subtract 1 "pixel" when
10750 computing width of the stretch.
10751 (reseat_at_next_visible_line_start): Undo the change made on
10752 2011-09-17 that saved paragraph information and restored it after
10753 the call to `reseat'. (Bug#9545)
10755 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10757 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
10758 and turn window cursor on if cleared (Bug#9415).
10760 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
10762 * search.c (boyer_moore): Take unibyte characters from pattern
10763 literally. (Bug#9458)
10765 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10767 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
10769 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
10771 Fix minor problem found by static checking.
10772 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
10773 initialized, to pacify gcc -Wuninitialized.
10775 * fileio.c: Report proper errno when syscall falls.
10776 (Finsert_file_contents): Save and restore errno,
10777 so that report_file_error outputs the correct diagnostic.
10778 (Fwrite_region) [CLASH_DETECTION]: Likewise.
10780 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10782 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
10784 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10786 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
10787 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
10789 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10791 * xdisp.c (reseat_at_next_visible_line_start): Keep information
10792 about the current paragraph and restore it after the call to reseat.
10794 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
10795 (bidi_find_paragraph_start): Search back for paragraph beginning
10796 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
10797 (bidi_move_to_visually_next): Only trigger paragraph-related
10798 computations when the last character is a newline or at EOB, not
10799 just any NEUTRAL_B. (Bug#9470)
10801 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
10802 truncated lines if point is covered by a display string. (Bug#9524)
10804 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
10806 * xselect.c: Relax test for outgoing X longs (Bug#9498).
10807 (cons_to_x_long): New function.
10808 (lisp_data_to_selection_data): Use it. Correct the test for
10809 short-versus-long data; it was negated. Break out of vector
10810 loop, for efficiency, when a long datum is discovered.
10812 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
10814 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
10816 2011-09-16 Eli Zaretskii <eliz@gnu.org>
10818 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
10819 GCC PR/17406) by declaring this function with external scope.
10821 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10823 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
10824 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
10826 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
10828 * editfns.c (Fformat): Correctly handle text properties on "%%".
10830 2011-09-15 Eli Zaretskii <eliz@gnu.org>
10832 * xterm.c (x_draw_composite_glyph_string_foreground):
10833 * w32term.c (x_draw_composite_glyph_string_foreground):
10834 * term.c (encode_terminal_code):
10835 * composite.c (composition_update_it, get_composition_id):
10836 * xdisp.c (get_next_display_element)
10837 (fill_composite_glyph_string): Add comments about special meaning
10838 of TAB characters in a composition.
10840 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10842 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
10843 This occurs when processing a multibyte format.
10844 Problem reported by Wolfgang Jenker.
10846 2011-09-15 Johan Bockgård <bojohan@gnu.org>
10848 * xdisp.c (try_cursor_movement): Only check for exact match if
10849 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
10851 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10853 Remove unused external symbols.
10854 * dispextern.h (calc_pixel_width_or_height): Remove decl.
10855 * xdisp.c (calc_pixel_width_or_height): Now static.
10856 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
10857 * indent.c (check_display_width):
10858 * w32term.c: Fix comment to match code.
10859 * xterm.c, xterm.h (x_catching_errors): Remove.
10861 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10863 * xselect.c: Use signed conversions more consistently (Bug#9498).
10864 (selection_data_to_lisp_data): Assume incoming selection data are
10865 signed integers, not unsigned. This is to be consistent with
10866 outgoing selection data, which was modified to use signed integers
10867 in as part of the fix to Bug#9196 in response to Jan D.'s comment
10868 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
10869 expects long, not unsigned long.
10871 2011-09-14 Eli Zaretskii <eliz@gnu.org>
10873 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
10874 computation of loop end. Reported by Johan Bockgård
10877 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
10879 * frame.c (Fother_visible_frames_p): Function deleted.
10881 2011-09-12 Eli Zaretskii <eliz@gnu.org>
10883 * indent.c (compute_motion): Process display vector front to back
10884 rather than the other way around. (Bug#2496)
10886 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
10888 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
10890 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
10892 * minibuf.c (Fread_from_minibuffer): Doc fix.
10894 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10896 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
10897 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
10899 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
10901 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
10902 value for non-existent files.
10904 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10906 * fileio.c (Finsert_file_contents): If the file cannot be opened,
10907 set its "size" to -1. This will set the modtime_size field of
10908 the corresponding buffer to -1, which is what
10909 verify-visited-file-modtime expects for files that do not exist.
10912 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
10914 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
10916 * lisp.h: ... from here. push_key_description is no longer
10917 defined in keyboard.c, so its declaration should not be in
10918 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
10919 logically belongs with push_key_description.
10921 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
10923 * buffer.h: Include <sys/types.h> instead of <time.h>.
10924 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
10925 Problem reported by Herbert J. Skuhra.
10927 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
10929 * xml.c (parse_region): Make the parsing work for
10930 non-comment-starting XML files again (bug#9144).
10932 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
10934 * image.c (gif_load): Fix calculation of bottom and right corner.
10937 2011-09-10 Eli Zaretskii <eliz@gnu.org>
10939 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
10940 redisplay in small windows.
10942 2011-09-09 Eli Zaretskii <eliz@gnu.org>
10944 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
10946 2011-09-08 Martin Rudalics <rudalics@gmx.at>
10948 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
10949 Operate on live windows only.
10951 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
10953 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
10955 2011-09-07 Eli Zaretskii <eliz@gnu.org>
10957 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
10958 only under bidi iteration.
10960 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
10962 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
10964 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10966 isnan: Fix porting problem to Solaris 10 with bundled gcc.
10967 Without this fix, the command to link temacs failed due to an
10968 undefined symbol __builtin_isnan. This is because
10969 /usr/include/iso/math_c99.h #defines isnan(x) to
10970 __builtin_isnan(x), but the bundled gcc, which identifies itself
10971 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
10973 * floatfns.c (isnan): #undef, and then #define to a clone of
10975 (Fisnan): Always define, since it's always available now.
10976 (syms_of_floatfns): Always define isnan at the Lisp level.
10978 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10980 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
10982 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10984 * fileio.c: Fix bugs with large file offsets (Bug#9428).
10985 The previous code assumed that file offsets (off_t values) fit in
10986 EMACS_INT variables, which is not true on typical 32-bit hosts.
10987 The code messed up by falsely reporting buffer overflow in cases
10988 such as (insert-file-contents "big" nil 1 2) into an empty buffer
10989 when "big" contains more than 2**29 bytes, even though this
10990 inserts just one byte and does not overflow the buffer.
10991 (Finsert_file_contents): Store file offsets as off_t
10992 values, not as EMACS_INT values. Check for overflow when
10993 converting between EMACS_INT and off_t. When checking for
10994 buffer overflow or for overlap, take the offsets into account.
10995 Don't use EMACS_INT for small values where int suffices.
10996 When checking for overlap, fix a typo: ZV was used where
10997 ZV_BYTE was intended.
10998 (Fwrite_region): Don't assume off_t fits into 'long'.
10999 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
11001 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
11003 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
11005 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
11007 sprintf-related integer and memory overflow issues (Bug#9412).
11009 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
11010 (esprintf, exprintf, evxprintf): New functions.
11011 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
11012 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
11013 (modify_event_symbol): Do not assume that the length of
11014 name_alist_or_stem is safe to alloca and fits in int.
11015 (Fexecute_extended_command): Likewise for function name and binding.
11016 (Frecursion_depth): Wrap around reliably on integer overflow.
11017 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
11018 since some callers pass EMACS_INT values.
11019 (Fsingle_key_description): Don't crash if symbol name contains more
11020 than MAX_ALLOCA bytes.
11021 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
11022 (get_minibuffer): Arg is now EMACS_INT, not int.
11023 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
11024 (esprintf, exprintf, evxprintf): New decls.
11025 * window.h (command_loop_level, minibuf_level): Reflect API changes.
11027 * dbusbind.c (signature_cat): New function.
11028 (xd_signature, Fdbus_register_signal):
11029 Do not overrun buffer; instead, report string overflow.
11031 * dispnew.c (add_window_display_history): Don't overrun buffer.
11032 Truncate instead; this is OK since it's just a log.
11034 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
11035 even if the time zone offset is outlandishly large.
11036 Don't mishandle offset == INT_MIN.
11038 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
11039 when creating daemon; the previous buffer-overflow check was incorrect.
11041 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
11042 which has the guts of the old verror function.
11044 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
11045 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
11047 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
11048 (font_unparse_xlfd): Don't blindly alloca long strings.
11049 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
11050 fits in int, when using sprintf. Use single snprintf to count
11051 length of string rather than counting it via multiple sprintfs;
11052 that's simpler and more reliable.
11053 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
11054 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
11055 sprintf, in case result does not fit in int.
11057 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
11058 (fontset_from_font): Print it.
11060 * frame.c (tty_frame_count): Now printmax_t, not int.
11061 (make_terminal_frame, set_term_frame_name): Print it.
11062 (x_report_frame_params): In X, window IDs are unsigned long,
11063 not signed long, so print them as unsigned.
11064 (validate_x_resource_name): Check for implausibly long names,
11065 and don't assume name length fits in 'int'.
11066 (x_get_resource_string): Don't blindly alloca invocation name;
11067 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
11070 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
11071 (xg_check_special_colors, xg_set_geometry):
11072 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
11074 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
11075 Use esprintf, not sprintf, in case result does not fit in int.
11077 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11078 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
11079 it as a large positive number.
11080 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
11081 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11083 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
11084 in case result does not fit in int.
11086 * print.c (float_to_string): Detect width overflow more reliably.
11087 (print_object): Make sprintf buffer a bit bigger, to avoid potential
11088 buffer overrun. Don't assume list length fits in 'int'. Treat
11089 print length of 0 as 0, not as infinity; to be consistent with other
11090 uses of print length in this function. Don't overflow print length
11091 index. Don't assume hash table size fits in 'long', or that
11092 vectorlike size fits in 'unsigned long'.
11094 * process.c (make_process): Use printmax_t, not int, to format
11095 process-name gensyms.
11097 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
11099 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
11100 to avoid potential buffer overrun.
11102 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
11103 if X resource line is longer than 512 bytes.
11105 * xfns.c (x_window): Make sprintf buffer a bit bigger
11106 to avoid potential buffer overrun.
11108 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
11110 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
11112 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
11114 Integer overflow fixes for scrolling, etc.
11115 Without these, Emacs silently mishandles large integers sometimes.
11116 For example, "C-u 4294967297 M-x recenter" was treated as if
11117 it were "C-u 1 M-x recenter" on a typical 64-bit host.
11119 * xdisp.c (try_window_id): Check Emacs fixnum range before
11120 converting to 'int'.
11122 * window.c (window_scroll_line_based, Frecenter):
11123 Check that an Emacs fixnum is in range before assigning it to 'int'.
11124 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
11125 values converted from Emacs fixnums.
11126 (Frecenter): Don't wrap around a line count if it is out of 'int'
11127 range; instead, treat it as an extreme value.
11128 (Fset_window_configuration, compare_window_configurations):
11129 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
11131 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
11132 that can exceed INT_MAX. Check that EMACS_INT value is in range
11133 before assigning it to the (possibly-narrower) index.
11134 (match_limit): Don't assume that a fixnum can fit in 'int'.
11136 * print.c (print_object): Use ptrdiff_t, not int, for index that can
11139 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
11140 (Fvertical_motion): Don't wrap around LINES values that don't fit
11141 in 'int'. Instead, treat them as extreme values. This is good
11142 enough for windows, which can't have more than INT_MAX lines anyway.
11144 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
11146 * Require libxml/parser.h to avoid compilation warning.
11148 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
11150 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
11151 since this reportedly can destroy thread storage.
11153 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
11155 * syntax.c (find_defun_start): Update all cache variables if
11156 exiting early (Bug#9401).
11158 2011-08-30 Eli Zaretskii <eliz@gnu.org>
11160 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
11162 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
11163 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
11164 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
11166 * term.c (tty_append_glyph): New function.
11167 (produce_stretch_glyph): Static function and its prototype deleted.
11169 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
11172 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
11174 * image.c (parse_image_spec): Check for nonnegative, not for positive,
11175 when checking :margin (Bug#9390).
11176 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
11177 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
11178 so that the name doesn't mislead. All uses changed.
11180 2011-08-28 Johan Bockgård <bojohan@gnu.org>
11182 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
11185 2011-08-27 Eli Zaretskii <eliz@gnu.org>
11187 * xdisp.c (move_it_to): Don't bail out early when reaching
11188 position beyond to_charpos, if we are scanning backwards.
11189 (move_it_vertically_backward): When DY == 0, make sure we get to
11190 the first character in the line after the newline.
11192 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
11194 * ccl.c: Improve and simplify overflow checking (Bug#9196).
11195 (ccl_driver): Do not generate an out-of-range pointer.
11196 (Fccl_execute_on_string): Remove unnecessary check for

11202 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
11204 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
11206 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
11208 Integer and memory overflow issues (Bug#9196).
11210 * doc.c (get_doc_string): Rework so that
11211 get_doc_string_buffer_size is the actual buffer size, rather than
11212 being 1 less than the actual buffer size; this makes xpalloc more
11215 * image.c (x_allocate_bitmap_record, cache_image):
11216 * xselect.c (Fx_register_dnd_atom):
11217 Simplify previous changes by using xpalloc.
11219 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
11220 since either will do and ptrdiff_t is convenient with xpalloc.
11222 * charset.c (charset_table_size)
11223 (struct charset_sort_data.priority): Now ptrdiff_t.
11224 (charset_compare): Don't overflow if priorities differ greatly.
11225 (Fsort_charsets): Don't assume list length fits in int.
11226 Check for size-calculation overflow when allocating sort data.
11227 (syms_of_charset): Allocate an initial charset table that is
11228 just under 64 KiB, to avoid problems with glibc malloc and mmap.
11230 * cmds.c (internal_self_insert): Check for size-calculation overflow.
11232 * composite.h (struct composition.glyph_len): Now int, not unsigned.
11233 The actual value is always <= INT_MAX, and leaving it unsigned made
11234 overflow checking harder.
11236 * dispextern.h (struct glyph_matrix.rows_allocated)
11237 (struct face_cache.size): Now ptrdiff_t, for convenience in use
11238 with xpalloc. The values are still always <= INT_MAX.
11240 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
11242 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
11243 (SAFE_NALLOCA): New macro.
11245 * region-cache.c (struct boundary.pos, find_cache_boundary)
11246 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
11247 (set_cache_region, invalidate_region_cache)
11248 (revalidate_region_cache, know_region_cache, region_cache_forward)
11249 (region_cache_backward, pp_cache):
11250 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
11251 so that ptrdiff_t * can be passed to xpalloc.
11252 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
11253 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
11254 (pp_cache): Don't assume cache_len fits in int.
11255 * region-cache.h: Adjust extern decls to match.
11257 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
11258 EMACS_INT, since either will do, for xpalloc.
11260 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
11261 (xnmalloc, xnrealloc, xpalloc): New functions.
11263 * bidi.c (bidi_shelve_header_size): New constant.
11264 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
11265 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
11267 * bidi.c (bidi_cache_shrink):
11268 * buffer.c (overlays_at, overlays_in, record_overlay_string)
11270 Don't update size of array until after memory allocation succeeds,
11271 because xmalloc/xrealloc may not return.
11272 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
11273 now that we have proper integer overflow checking.
11274 (record_overlay_string, overlay_strings): Catch overflows when
11275 calculating size of overlay_str_buf.
11277 * callproc.c (Fcall_process): Check for size overflow when
11278 calculating size of args2.
11279 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
11280 Normally we prefer signed values, but sticking with ptrdiff_t would
11281 require adding more-complicated checks.
11283 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
11284 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
11285 Redo buffer-overflow calculations to avoid integer overflow.
11286 Add a FIXME comment where memory seems to be over-allocated.
11288 * character.c (Fstring): Check for size-calculation overflow.
11290 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
11291 unnecessary integer overflow. Check for size overflow.
11292 (encode_coding_object): Don't update size until xmalloc succeeds.
11294 * composite.c (get_composition_id): Check for overflow in glyph
11295 length calculations.
11297 Integer and memory overflow fixes for display code.
11298 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
11299 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
11300 (scrolling_window): Check for overflow in size calculations.

11312 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
11313 (get_doc_string): Check for size calculation overflow.
11314 Don't update size until allocation succeeds.
11315 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
11316 EMACS_INT, where ptrdiff_t will do.
11317 (Fsubstitute_command_keys): Check for string overflow.
11319 * editfns.c (set_time_zone_rule): Don't assume environment length
11321 (message_length): Now ptrdiff_t, not int.
11322 (Fmessage_box): Don't update size until allocation succeeds.
11323 Don't assume message length fits in int.
11324 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
11326 * emacs.c (main): Do not reallocate argv, since there is a null at
11327 the end that can be overwritten, and this way there's no need to
11328 worry about size-calculation overflow.
11329 (sort_args): Check for size-calculation overflow.
11331 * eval.c (init_eval_once, grow_specpdl): Don't update size until
11333 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
11335 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
11336 (x_set_scroll_bar_width, x_figure_window_size):
11337 Check for integer overflow.
11338 (x_set_alpha): Do not assume XINT fits in int.
11340 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
11341 This is for the members text_lines, text_cols, total_lines, total_cols,
11342 where the system imposes an 'int' limit.
11344 * fringe.c (Fdefine_fringe_bitmap):
11345 Don't update size until alloc works.
11347 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
11348 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
11350 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
11351 Check for size-calculation overflow.
11352 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
11353 do, as we prefer signed integers.
11354 (id_to_widget.max_size, id_to_widget.used)
11355 (xg_store_widget_in_map, xg_remove_widget_from_map)
11356 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
11357 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
11358 Use and return ptrdiff_t, not int.
11359 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
11360 * gtkutil.h: Change prototypes to match the above.
11362 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
11363 are duplicate now that they've been promoted to lisp.h.
11364 (x_allocate_bitmap_record, x_alloc_image_color)
11365 (make_image_cache, cache_image, xpm_load):
11366 Don't update size until alloc is done.

11379 calculations. Don't update size until allocation succeeds.
11380 Redo calculations to avoid overflow.
11381 * keyboard.h: Change prototypes to match the above.
11383 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
11385 (current_minor_maps): Check for size calculation overflow.
11386 * keymap.h: Change prototypes to match the above.
11388 * lread.c (read1, init_obarray): Don't update size until alloc done.
11390 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

11393 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
11394 Now ptrdiff_t, not int.
11395 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

11409 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
11410 for command line length. Do not attempt to address one before the
11411 beginning of an array, as that's not portable.
11413 * term.c (max_frame_lines): Remove; unused.
11414 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
11416 (encode_terminal_code, calculate_costs): Check for size
11417 calculation overflow.

11423 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
11424 subtracting pointers.
11425 (gobble_line): Check for overflow more carefully. Don't update size
11428 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
11429 Don't update size until alloc done.
11430 Redo size calculations to avoid overflow.
11431 Check for size calculation overflow.

11439 Use ptrdiff_t, not int, for sizes.
11440 (Finternal_make_lisp_face, cache_face):
11441 Check for size calculation overflow.
11442 (cache_face): Treat size calculation overflows as if they were
11443 memory exhaustion (the usual treatment), rather than aborting.
11445 * xfns.c (x_encode_text, x_set_name_internal)
11446 (Fx_change_window_property): Use ptrdiff_t, not int, to count
11447 sizes, since they can exceed INT_MAX in size. Check for size
11448 calculation overflow.

11451 (xg_select): Check for size calculation overflow.
11452 Don't update size until alloc done.
11454 * xrdb.c (get_environ_db): Don't assume path length fits in int,
11455 as sprintf is limited to int lengths.
11457 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
11458 (X_LONG_MIN): New macros.
11459 Use them to make the following changes clearer.
11460 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
11461 This change doesn't affect the value now, but it may help remind
11462 future maintainers not to raise the value too much later.
11463 (SELECTION_QUANTUM): Remove, replacing with ...
11464 (selection_quantum): ... new function, which avoids overflow.
11466 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
11467 assumption that selection length fits in 'int'.
11468 (x_reply_selection_request, x_handle_selection_request)
11469 (x_get_window_property, receive_incremental_selection)
11470 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
11471 (lisp_data_to_selection_data, clean_local_selection_data):
11472 Use ptrdiff_t, not int, to record length of selection.
11473 (x_reply_selection_request, x_get_window_property)

11475 Redo calculations to avoid overflow.
11476 (x_reply_selection_request): When sending hint, ceiling it at

11479 (x_get_window_property, receive_incremental_selection)
11480 (lisp_data_to_selection_data, x_property_data_to_lisp):
11481 Check for size-calculation overflow.
11482 (x_get_window_property, receive_incremental_selection)
11483 (lisp_data_to_selection_data, Fx_register_dnd_atom):
11484 Don't store size until memory allocation succeeds.
11485 (x_get_window_property): Plug memory leak on memory exhaustion.
11486 Don't double-block input; malloc is safe here. Don't assume 2**34
11487 - 4 fits in unsigned long. Add an xassert to check
11488 XGetWindowProperty overflow. Be more careful about overflow
11489 calculations, and distinguish size from memory overflow better.
11490 (receive_incremental_selection): When tracing, don't assume
11491 unsigned int is less than INT_MAX.
11492 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
11493 harmful) conversions of unsigned short to int.
11494 (lisp_data_to_selection_data): Don't assume that integers
11495 in the range -65535 through -1 fit in an X unsigned short.
11496 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
11497 result parameters unless successful. Rely on cons_to_unsigned
11498 to report problems with elements; the old code wasn't right anyway.
11499 (x_check_property_data): Check for int overflow; we cannot use
11500 a wider type due to X limits.
11501 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
11503 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
11505 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
11506 (x_term_init): Check for size calculation overflow.
11507 (x_color_cells): Don't store size until memory allocation succeeds.
11508 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
11509 Don't assume alloca size is less than MAX_ALLOCA.
11510 (x_term_init): Don't assume length fits in int (sprintf is limited
11513 Use ptrdiff_t for composition IDs.

11532 * image.c (xpm_get_color_table_h):
11533 * lisp.h (hash_lookup, hash_put):
11534 * minibuf.c (Ftest_completion):
11535 Use ptrdiff_t for hash table indexes, not int (which is too
11536 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
11537 32-bit --with-wide-int hosts).
11539 * charset.c (Fdefine_charset_internal): Check for integer overflow.
11540 Add a FIXME comment about memory leaks.
11541 (syms_of_charset): Don't assume xmalloc returns.
11543 Don't assume that stated character widths fit in int.
11544 * character.c (Fchar_width, c_string_width, lisp_string_width):
11545 * character.h (CHAR_WIDTH):
11546 * indent.c (MULTIBYTE_BYTES_WIDTH):
11547 Use sanitize_char_width to avoid undefined and/or bad behavior
11548 with outlandish widths.
11549 * character.h (sanitize_tab_width): Rename from sanitize_width,
11550 now that we have two such functions. All uses changed.
11551 (sanitize_char_width): New inline function.
11553 Don't assume that tab-width fits in int.
11554 * character.h (sanitize_width): New inline function.
11555 (SANE_TAB_WIDTH): New macro.
11556 (ASCII_CHAR_WIDTH): Use it.

11561 * fileio.c: Integer overflow issues with file modes.
11562 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
11564 * charset.c (read_hex): New arg OVERFLOW. All uses changed.

11568 * xterm.c: Don't go over XClientMessageEvent limit.
11569 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
11570 (x_send_scroll_bar_event): Likewise. Check that the size does not
11571 exceed limits imposed by XClientMessageEvent, as well as the usual
11572 ptrdiff_t and size_t limits.
11574 * keyboard.c: Overflow, signedness and related fixes.
11575 (make_lispy_movement): Use same integer type in forward decl
11576 that is used in the definition.
11577 (read_key_sequence, keyremap_step):
11578 Change bufsize argument back to int, undoing my 2011-03-30 change.
11579 We prefer signed types, and int is wide enough here.
11580 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
11581 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
11582 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
11583 length, not size_t. Use ptrdiff_t for index, not int.
11584 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
11585 possibility of integer overflow.
11587 Overflow, signedness and related fixes for images.
11589 * dispextern.h (struct it.stack[0].u.image.image_id)
11590 (struct_it.image_id, struct image.id, struct image_cache.size)
11591 (struct image_cache.used, struct image_cache.ref_count):
11592 * gtkutil.c (update_frame_tool_bar):
11593 * image.c (x_reference_bitmap, Fimage_size, Fimage_mask_p)
11594 (Fimage_metadata, free_image_cache, clear_image_cache, lookup_image)
11595 (cache_image, mark_image_cache, x_kill_gs_process, Flookup_image):
11596 * nsmenu.m (update_frame_tool_bar):
11597 * xdisp.c (calc_pixel_width_or_height):
11598 * xfns.c (image_cache_refcount):
11599 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
11600 on typical 64-bit hosts.

11608 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
11609 (lookup_image): Remove unnecessary tests.
11610 (xbm_image_p): Locals are now of int, not EMACS_INT,
11611 since parse_image_check makes sure they fit into int.
11612 (png_load, gif_load, svg_load_image):
11613 Prefer int to unsigned where either will do.
11614 (tiff_handler): New function, combining the cores of the
11615 old tiff_error_handler and tiff_warning_handler.
11616 This function is rewritten to use vsnprintf and thereby avoid
11617 stack buffer overflows. It uses only the features of vsnprintf
11618 that are common to both POSIX and native Microsoft.
11619 (tiff_error_handler, tiff_warning_handler): Use it.
11620 (tiff_load, gif_load, imagemagick_load_image):
11621 Don't assume :index value fits in 'int'.
11622 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.

11642 `(space ...)', and specifies display in the text area, return 2
11644 (try_cursor_movement): Check for the need to scroll more
11645 accurately, and prefer exact match for point under bidi.
11646 Don't advance `row' beyond the last row of the window.

11699 * xdisp.c (redisplay_window): When computing centering_position,
11700 account for the height of the header line. (Bug#8874)
11702 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
11703 instead of CHAR_TO_BYTE. Fixes a crash when a completion
11704 candidate is selected by the mouse, and that candidate has a
11705 composed character under the mouse.
11707 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
11708 coordinates reported by pos-visible-in-window-p for a composed
11709 character in column zero.

11719 composed buffer positions.
11721 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
11723 * image.c (gif_load): Don't assume that each subimage has the same
11724 dimensions as the base image. Handle disposal method that is
11725 "undefined" by the gif spec (Bug#9335).

11735 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
11736 from an Org mode buffer to a Speedbar frame.
11738 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
11739 a composition, take its buffer position from IT->cmp_it.charpos.
11740 Fixes cursor positioning at the beginning of a line that begins
11741 with a composed character.
11743 2011-08-18 Eli Zaretskii <eliz@gnu.org>
11745 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
11746 character bidirectional type, use STRONG_L instead. Fixes crashes
11747 in a buffer produced by `describe-categories'.
11749 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
11750 members before the level stack, so they would be saved and
11751 restored when copying iterator state. Fixes incorrect reordering
11752 around TABs covered by display properties.

11889 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
11890 properties. (Bug#9284)

12099 2011-07-28 Eli Zaretskii <eliz@gnu.org>
12101 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
12104 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12106 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
12107 Without this fix, if a signal arrives just after memory fills up,
12108 'malloc' might be invoked reentrantly.
12110 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
12111 In other words, assume that every image size is allowed, on non-X
12112 hosts. This assumption is probably wrong, but it lets Emacs compile.
12114 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
12116 * regex.c (re_iswctype): Convert return values to boolean.
12118 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
12120 * xdisp.c (compute_display_string_pos): Don't use cached display
12121 string position if the buffer had its restriction changed.
12124 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12126 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12128 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12130 Integer signedness and overflow and related fixes. (Bug#9079)
12132 * bidi.c: Integer size and overflow fixes.
12133 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
12134 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
12135 (bidi_cache_find_level_change, bidi_cache_ensure_space)
12136 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
12137 (bidi_find_other_level_edge):
12138 Use ptrdiff_t instead of EMACS_INT where either will do.
12139 This works better on 32-bit hosts configured --with-wide-int.
12140 (bidi_cache_ensure_space): Check for size-calculation overflow.
12141 Use % rather than repeated addition, for better worst-case speed.
12142 Don't set bidi_cache_size until after xrealloc returns, because it
12144 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
12145 (bidi_cache_ensure_space): Also check that the bidi cache size
12146 does not exceed that of the largest Lisp string or buffer. See Eli
12147 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
12149 * alloc.c (__malloc_size_t): Remove.
12150 All uses replaced by size_t. See Andreas Schwab's note
12151 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
12153 * image.c: Improve checking for integer overflow.
12154 (check_image_size): Assume that f is nonnull, since
12155 it is always nonnull in practice. This is one less thing to
12156 worry about when checking for integer overflow later.
12157 (x_check_image_size): New function, which checks for integer
12158 overflow issues inside X.
12159 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
12160 This removes the need for a memory_full check.
12161 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
12162 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
12163 (xbm_read_bitmap_data): Change locals back to 'int', since
12164 their values must fit in 'int'.
12165 (xpm_load_image, png_load, tiff_load):
12166 Invoke x_create_x_image_and_pixmap earlier,
12167 to avoid much needless work if the image is too large.
12168 (tiff_load): Treat overly large images as if
12169 x_create_x_image_and_pixmap failed, not as malloc failures.
12170 (gs_load): Use x_check_image_size.
12172 * gtkutil.c: Omit integer casts.
12173 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
12174 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
12176 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
12178 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
12179 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
12180 would wrongly return t on a 64-bit host.
12182 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
12183 The plain *_OVERFLOW macros run afoul of GCC bug 49705
12184 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
12185 and therefore cause GCC to emit a bogus diagnostic in some cases.
12187 * image.c: Integer signedness and overflow and related fixes.
12188 This is not an exhaustive set of fixes, but it's time to
12189 record what I've got.
12190 (lookup_pixel_color, check_image_size): Remove redundant decls.
12191 (check_image_size): Don't assume that arbitrary EMACS_INT values
12192 fit in 'int', or that arbitrary 'double' values fit in 'int'.
12193 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
12194 (tiff_load, imagemagick_load_image):
12195 Check for overflow in size calculations.
12196 (x_create_x_image_and_pixmap): Remove unnecessary test for
12197 xmalloc returning NULL; that can't happen.
12198 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
12199 (xpm_color_bucket): Use better integer hashing function.
12200 (xpm_cache_color): Don't possibly over-allocate memory.
12201 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
12202 (gif_memory_source):
12203 Use ptrdiff_t, not int or size_t, to record sizes.
12204 (png_load): Don't assume values greater than 2**31 fit in 'int'.
12205 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
12206 either works, as we prefer signed integers.
12207 (tiff_read_from_memory, tiff_write_from_memory):
12208 Return tsize_t, not size_t, since that's what the TIFF API wants.
12209 (tiff_read_from_memory): Don't fail simply because the read would
12210 go past EOF; instead, return a short read.
12211 (tiff_load): Omit no-longer-needed casts.
12212 (Fimagemagick_types): Don't assume size fits into 'int'.
12214 Improve hashing quality when configured --with-wide-int.
12215 * fns.c (hash_string): New function, taken from sxhash_string.
12216 Do not discard information about ASCII character case; this
12217 discarding is no longer needed.
12218 (sxhash-string): Use it. Change sig to match it. Caller changed.
12219 * lisp.h: Declare it.
12220 * lread.c (hash_string): Remove, since we now use fns.c's version.
12221 The fns.c version returns a wider integer if --with-wide-int is
12222 specified, so this should help the quality of the hashing a bit.
12224 * emacs.c: Integer overflow minor fix.
12225 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
12226 Define only if GNU_LINUX.
12227 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
12229 * dispnew.c: Integer signedness and overflow fixes.
12230 Remove unnecessary forward decls, that were a maintenance hassle.
12231 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
12233 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
12234 (scrolling_window): Use ptrdiff_t, not int, for byte count.
12235 (prepare_desired_row, line_draw_cost):
12236 Use int, not unsigned, where either works.
12237 (save_current_matrix, restore_current_matrix):
12238 Use ptrdiff_t, not size_t, where either works.
12239 (init_display): Check for overflow more accurately, and without
12240 relying on undefined behavior.
12242 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
12243 Remove, replacing with the new symbols in lisp.h. All uses changed.
12244 * fileio.c (make_temp_name):
12245 * filelock.c (lock_file_1, lock_file):
12246 * xdisp.c (message_dolog):
12247 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
12248 Use pMd etc. instead.
12249 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
12250 replacing the pWIDE etc. symbols removed from editfns.c.
12252 * keyboard.h (num_input_events): Now uintmax_t.
12253 This is (very slightly) less likely to mess up due to wraparound.
12256 * buffer.c: Integer signedness fixes.
12257 (alloc_buffer_text, enlarge_buffer_text):
12258 Use ptrdiff_t rather than size_t when either will do, as we prefer
12261 * alloc.c: Integer signedness and overflow fixes.
12262 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
12263 (__malloc_size_t): Default to size_t, not to int.
12264 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
12265 (Fgarbage_collect, mark_object_loop_halt, mark_object):
12266 Prefer ptrdiff_t to size_t when either would do, as we prefer
12268 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
12269 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
12270 Now const. Initialize with values that are in range even if char
12272 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
12273 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
12274 These functions do the right thing with sizes > 2**32.
12275 (check_depth): Now ptrdiff_t, not int.
12276 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
12277 Adjust to new way of storing sizes. Check for size overflow bugs
12279 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
12280 slightly wrong anyway, as it missed one instance of
12281 XMALLOC_OVERRUN_CHECK_OVERHEAD.
12282 (refill_memory_reserve): Omit needless cast to size_t.
12283 (mark_object_loop_halt): Mark as externally visible.
12285 * xselect.c: Integer signedness and overflow fixes.
12286 (Fx_register_dnd_atom, x_handle_dnd_message):
12287 Use ptrdiff_t, not size_t, since we prefer signed.
12288 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
12289 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
12290 x_dnd_atoms_size and x_dnd_atoms_length.
12292 * doprnt.c: Prefer signed to unsigned when either works.
12294 * doprnt.c (doprnt):
12296 * xdisp.c (vmessage):
12297 Use ptrdiff_t, not size_t, when using or implementing doprnt,
12298 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
12299 prefer signed arithmetic to avoid comparison confusion.
12300 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
12301 but is a bit tricky.
12303 Assume freestanding C89 headers, string.h, stdlib.h.
12304 * data.c, doprnt.c, floatfns.c, print.c:
12305 Include float.h unconditionally.
12306 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
12307 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
12308 * regex.c: Likewise for stddef.h, string.h.
12309 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
12310 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
12311 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
12312 (STDC_HEADERS): Remove obsolete defines.
12313 * sysdep.c: Include limits.h unconditionally.
12315 Assume support for memcmp, memcpy, memmove, memset.
12316 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
12317 * regex.c (memcmp, memcpy):
12318 Remove; we assume C89 now.
12320 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
12321 (__malloc_safe_bcopy): Remove; no longer needed.
12323 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
12324 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
12325 well either way, and we prefer signed to unsigned.
12327 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
12329 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
12330 closes the connection while we're reading (bug#9182).
12332 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
12334 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
12335 are specified (Bug#9168).
12337 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
12339 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
12340 Found by GCC static checking and --with-wide-int on a 32-bit host.
12342 2011-07-25 Eli Zaretskii <eliz@gnu.org>
12344 * xdisp.c (compute_display_string_pos): Fix logic of caching
12345 previous display string position. Initialize cached_prev_pos to
12346 -1. Fixes slow-down at the beginning of a buffer.
12348 2011-07-24 Eli Zaretskii <eliz@gnu.org>
12350 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
12351 for attrs[LFACE_FONTSET_INDEX].
12353 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
12355 * xml.c (parse_region): Remove unused local
12356 that was recently introduced.
12358 2011-07-23 Eli Zaretskii <eliz@gnu.org>
12360 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
12361 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
12363 * xdisp.c (move_it_in_display_line_to): Record the best matching
12364 position for TO_CHARPOS while scanning the line, and restore it on
12365 exit if none of the characters scanned was an exact match.
12366 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
12367 when exact match is impossible due to invisible text, and the
12368 lines are truncated.
12370 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
12372 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
12375 2011-07-22 Eli Zaretskii <eliz@gnu.org>
12377 Fix a significant slow-down of cursor motion with C-n, C-p,
12378 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
12379 auto-repeat under bidi redisplay in fontified buffers.
12380 * xdisp.c (compute_stop_pos_backwards): New function.
12381 (next_element_from_buffer): Call compute_stop_pos_backwards to
12382 find a suitable prev_stop when we find ourselves before
12384 (reseat): Don't look for prev_stop, as that could mean a very long
12386 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
12387 <cached_disp_overlay_modiff>: Cache for last found display string
12389 (compute_display_string_pos): Return the cached position if asked
12390 about the same buffer in the same area of character positions, and
12391 the buffer wasn't changed since the time the display string
12392 position was cached.
12394 2011-07-22 Eli Zaretskii <eliz@gnu.org>
12396 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
12397 is an integer, which is important for empty lines. (Bug#9149)
12399 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
12401 * frame.c (Fmodify_frame_parameters): In tty case, update the
12402 default face if necessary (Bug#4238).
12404 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
12406 * editfns.c (Fstring_to_char): No need to explain what a character
12407 is in the docstring (Bug#6576).
12409 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
12411 * xml.c (parse_region): Make sure we always return a tree.
12413 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
12415 * xml.c (parse_region): If a document contains only comments,
12418 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
12420 * xml.c (make_dom): Return comments, too.
12422 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
12425 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
12426 and the surrounding thread.
12427 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
12428 rather than fgets, and retry after EINTR. Otherwise, 'emacs
12429 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
12431 * s/openbsd.h (BROKEN_SIGIO): Define.
12432 * unexelf.c (unexec) [__OpenBSD__]:
12433 Don't update the .mdebug section of the Alpha COFF symbol table.
12435 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12437 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
12440 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
12442 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
12443 This fixes some race conditions on the permissions of any newly
12446 * alloc.c (valid_pointer_p): Use pipe, not open.
12447 This fixes some permissions issues when debugging.
12449 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
12450 If fchown fails to set both uid and gid, try to set just gid,
12451 as that is sometimes allowed. Adjust the file's mode to eliminate
12452 setuid or setgid bits that are inappropriate if fchown fails.
12454 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
12456 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
12457 to compare Lisp_Objects.
12458 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
12459 global_gnutls_log_level, don't mistake it for a Lisp_Object.
12460 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
12462 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
12464 * lread.c (read_integer): Unread even EOF character.
12465 (read1): Likewise. Properly record start position of symbol.
12467 * lread.c (read1): Read `#:' as empty uninterned symbol if no
12468 symbol character follows.
12470 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
12472 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
12473 This works around a problem with the previous change to Fcopy_file.
12474 Recent glibc declares fchown with __attribute__((warn_unused_result)),
12475 and without this change, GCC might complain about discarding
12476 fchown's return value.
12478 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
12480 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
12482 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
12484 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
12486 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
12488 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
12489 it's used from the C level.
12491 * process.c: Use the same condition for POLL_FOR_INPUT in both
12492 keyboard.c and process.c (bug#1858).
12494 2011-07-09 Lawrence Mitchell <wence@gmx.li>
12496 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
12497 (Fgnutls_boot): Use it.
12499 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
12501 * doc.c (Fsubstitute_command_keys): Revert last change.
12503 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
12505 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
12506 quotes the next character, and doesn't affect other longer
12507 sequences (bug#8935).
12509 * lread.c (syms_of_lread): Clarify that is isn't only
12510 `eval-buffer' and `eval-defun' that's affected by
12511 `lexical-binding' (bug#8460).
12513 2011-07-15 Eli Zaretskii <eliz@gnu.org>
12515 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
12516 bidi redisplay when a line includes both an image and is truncated.
12518 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
12520 Fix minor problems found by static checking.
12521 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
12522 (elsz): Now a signed constant, not a size_t var. We prefer signed
12523 types to unsigned, to avoid integer comparison confusion. Without
12524 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
12525 "cannot optimize loop, the loop counter may overflow", a symptom
12527 * indent.c (Fvertical_motion): Mark locals as initialized.
12528 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
12530 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
12532 * search.c (Fre_search_backward): Mention `case-fold-search' in
12533 all the re_search_* functions (bug#8138).
12535 * keyboard.c (Fopen_dribble_file): Document when the file is
12538 2011-07-14 Eli Zaretskii <eliz@gnu.org>
12540 * bidi.c (bidi_dump_cached_states): Fix format of displaying

13052 (clone_per_buffer_values): Don't assume that

13056 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
13057 New macros, used in the buffer.c change.

13093 Random fixes. E.g., (random) never returned negative values.
13094 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
13095 subseconds part to the entropy, as that's a bit more random.
13096 Prefer signed to unsigned, since the signedness doesn't matter and
13097 in general we prefer signed. When given a limit, use a
13098 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
13099 latter isn't right if USE_2_TAGS_FOR_INTS.
13100 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
13101 not 0..VALMASK. Don't discard "excess" bits that random () returns.

13113 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
13114 This is more efficient than Ffile_directory_p and avoids a minor race.

13118 * buffer.c (Foverlay_put): Say what the return value is
13121 * fileio.c (barf_or_query_if_file_exists): Check first if the file

13125 error be more correct.
13127 * fns.c (Frequire): Remove the mention of the .gz files, since
13128 that's installation-specific, but keep the mention of

13141 Qgnutls_bootprop_verify_error (which is no longer used).
13143 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
13144 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
13145 Also (re)move comments that are misplaced or no longer relevant.
13147 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13149 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

13174 * lread.c (syms_of_lread): Mention single symbols defined by

13246 * eval.c (struct backtrace): Simplify and port the data structure.
13247 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
13248 signed bit field, as this assumption is not portable and it makes
13249 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
13250 "char debug_on_exit : 1" as this is not portable either; instead,
13251 use the portable "unsigned int debug_on_exit : 1". Remove unused
13252 member evalargs. Remove obsolete comments about cc bombing out.
13254 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

13416 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
13418 Integer and buffer overflow fixes (Bug#8873).
13420 * print.c (printchar, strout): Check for string overflow.
13421 (PRINTPREPARE, printchar, strout):
13422 Don't set size unless allocation succeeds.
13424 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
13425 for sizes. Check for string overflow more accurately.
13426 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
13428 * macros.c: Integer and buffer overflow fixes.
13429 * keyboard.h (struct keyboard.kbd_macro_bufsize):
13430 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
13431 Use ptrdiff_t, not int, for sizes.
13432 Don't increment bufsize until after realloc succeeds.
13433 Check for size-calculation overflow.
13434 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
13436 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
13438 * lread.c: Integer overflow fixes.
13439 (read_integer): Radix is now EMACS_INT, not int,
13440 to improve quality of diagnostics for out-of-range radices.
13441 Calculate buffer size correctly for out-of-range radices.
13442 (read1): Check for integer overflow in radices, and in
13443 read-circle numbers.
13444 (read_escape): Avoid int overflow.
13445 (Fload, openp, read_buffer_size, read1)
13446 (substitute_object_recurse, read_vector, read_list, map_obarray):
13447 Use ptrdiff_t, not int, for sizes.
13448 (read1): Use EMACS_INT, not int, for sizes.
13449 Check for size overflow.
13451 * image.c (cache_image): Check for size arithmetic overflow.
13453 * lread.c: Integer overflow issues.
13454 (saved_doc_string_size, saved_doc_string_length)
13455 (prev_saved_doc_string_size, prev_saved_doc_string_length):
13456 Now ptrdiff_t, not int.
13457 (read1): Don't assume doc string length fits in int. Check for
13458 out-of-range doc string lengths.

13460 (read_escape): Check for hex character overflow.
13462 2011-06-22 Leo Liu <sdl.web@gmail.com>
13464 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
13465 Move to minibuffer.el.
13467 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
13469 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
13470 The following patches are for when GLYPH_DEBUG && !XASSERT.
13471 * dispextern.h (trace_redisplay_p, dump_glyph_string):
13472 * dispnew.c (flush_stdout):
13473 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
13474 Mark as externally visible.
13475 * dispnew.c (check_window_matrix_pointers): Now static.
13476 * dispnew.c (window_to_frame_vpos):
13477 * xfns.c (unwind_create_frame):
13478 * xterm.c (x_check_font): Remove unused local.
13479 * scroll.c (CHECK_BOUNDS):
13480 * xfaces.c (cache_fache): Rename local to avoid shadowing.
13481 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
13482 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
13483 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
13484 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
13486 (debug_method_add): Use va_list and vsprintf rather than relying
13487 on undefined behavior with wrong number of arguments.
13488 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
13489 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
13490 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
13491 since we're not interested in debugging glyphs with old libraries.
13492 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
13493 GCC 4.6.0's static checking.
13495 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
13497 Integer overflow and signedness fixes (Bug#8873).

13506 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
13507 (x_create_bitmap_from_xpm_data):
13508 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
13509 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
13511 * xfaces.c (load_pixmap):
13512 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
13513 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
13514 (.bitmaps_last, struct x_output.icon_bitmap):
13515 Use ptrdiff_t, not int, for bitmap indexes.
13516 (x_allocate_bitmap_record): Check for size overflow.
13517 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
13519 Use ptrdiff_t, not int, for overlay counts.
13520 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
13521 * editfns.c (overlays_around, get_pos_property):
13522 * textprop.c (get_char_property_and_overlay):
13523 * xdisp.c (next_overlay_change, note_mouse_highlight):
13524 * xfaces.c (face_at_buffer_position):
13525 * buffer.c (OVERLAY_COUNT_MAX): New macro.
13526 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
13527 (Fnext_overlay_change, Fprevious_overlay_change)
13528 (mouse_face_overlay_overlaps, Foverlays_in):
13529 Use ptrdiff_t, not int, for sizes.
13530 (overlays_at, overlays_in): Check for size-calculation overflow.
13532 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
13534 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
13535 (x_session_initialize): Do not assume string length fits in int.
13537 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
13538 This is unlikely, but can occur if DPI is outlandish.
13540 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
13541 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
13543 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
13544 * xrdb.c (magic_file_p, search_magic_path):
13545 Omit last arg SUFFIX; it was always 0. All callers changed.
13546 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
13548 * xfont.c (xfont_match): Avoid need for strlen.
13550 * xfns.c: Don't assume strlen fits in int.
13551 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
13553 * xdisp.c (message_log_check_duplicate): Return intmax_t,
13554 not unsigned long, as we prefer signed integers. All callers changed.
13555 Detect integer overflow in repeat count.
13556 (message_dolog): Don't assume print length fits in 39 bytes.
13557 (display_mode_element): Don't assume strlen fits in int.
13559 * termcap.c: Don't assume sizes fit in int and never overflow.
13560 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
13561 (gobble_line): Check for size-calculation overflow.
13563 * minibuf.c (Fread_buffer):
13564 * lread.c (intern, intern_c_string):
13565 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
13566 Don't assume string length fits in int.
13568 * keyboard.c (parse_tool_bar_item):
13569 * gtkutil.c (style_changed_cb): Avoid need for strlen.
13571 * font.c: Don't assume string length fits in int.
13572 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
13573 Use ptrdiff_t, not int.
13574 (font_intern_prop): Don't assume string length fits in int.
13575 Don't assume integer property fits in fixnum.
13576 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
13578 * filelock.c: Fix some buffer overrun and integer overflow issues.
13579 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
13580 Reformulate so as not to need the command string.
13581 Invoke gzip -cd rather than gunzip, as it's more portable.
13582 (lock_info_type, lock_file_1, lock_file):
13583 Don't assume pid_t and time_t fit in unsigned long.
13584 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
13585 (current_lock_owner): Prefer signed type for sizes.
13586 Use memcpy, not strncpy, where memcpy is what is really wanted.
13587 Don't assume (via atoi) that time_t and pid_t fit in int.
13588 Check for time_t and/or pid_t out of range, e.g., via a network share.
13589 Don't alloca where an auto var works fine.
13591 * fileio.c: Fix some integer overflow issues.
13592 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
13593 Don't assume string length fits in int.
13594 (directory_file_name): Don't assume string length fits in long.
13595 (make_temp_name): Don't assume pid fits in int, or that its print
13596 length is less than 20.
13598 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
13600 * coding.c (make_subsidiaries): Don't assume string length fits in int.
13602 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
13604 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
13605 We prefer signed integers, even for size calculations.
13607 * emacs.c: Don't assume string length fits in 'int'.
13608 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
13609 (main): Don't invoke strlen when not needed.
13611 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
13612 (XD_DEBUG_MESSAGE): Don't waste a byte.
13614 * callproc.c (getenv_internal_1, getenv_internal)
13615 (Fgetenv_internal):
13616 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
13618 * lread.c (invalid_syntax): Omit length argument.
13619 All uses changed. This doesn't fix a bug, but it simplifies the
13620 code away from its former Hollerith-constant appearance, and it's
13621 one less 'int' to worry about when looking at integer-overflow issues.
13622 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
13624 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
13625 This didn't break anything, but it didn't help either.
13626 It's confusing to put a bogus integer in a place where the actual
13627 value does not matter.
13628 (LIST_END_P): Remove unused macro and its bogus comment.
13629 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
13631 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
13632 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
13634 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
13635 We prefer signed types, and the value cannot exceed the EMACS_INT
13636 range anyway (because otherwise the length would not be representable).
13637 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
13638 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
13639 This avoids a GCC warning when WIDE_EMACS_INT.
13641 * indent.c (sane_tab_width): New function.
13642 (current_column, scan_for_column, Findent_to, position_indentation)
13643 (compute_motion): Use it. This is just for clarity.
13644 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
13646 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
13648 * lisp.h (lint_assume): New macro.
13649 * composite.c (composition_gstring_put_cache):
13650 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
13652 * editfns.c, insdel.c:
13653 Omit unnecessary forward decls, to simplify future changes.
13655 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
13657 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
13659 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
13660 Use much-faster test for byte-length change.
13661 Don't assume string byte-length fits in 'int'.
13662 Check that character arg fits in 'int'.
13663 (mapcar1): Declare byte as byte, for clarity.
13665 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
13667 * fns.c (concat): Catch string overflow earlier.
13668 Do not rely on integer wraparound.
13670 * dispextern.h (struct it.overlay_strings_charpos)
13671 (struct it.selective): Now EMACS_INT, not int.
13672 * xdisp.c (forward_to_next_line_start)
13673 (back_to_previous_visible_line_start)
13674 (reseat_at_next_visible_line_start, next_element_from_buffer):
13675 Don't arbitrarily truncate the value of 'selective' to int.
13677 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
13679 * composite.c: Don't truncate sizes to 'int'.
13680 (composition_gstring_p, composition_reseat_it)
13681 (composition_adjust_point): Use EMACS_INT, not int.
13682 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
13683 not EMACS_UINT, for indexes.
13685 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
13687 * buffer.c: Include <verify.h>.
13688 (struct sortvec.priority, struct sortstr.priority):
13689 Now EMACS_INT, not int.
13690 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
13691 (struct sortstr.size, record_overlay_string)
13692 (struct sortstrlist.size, struct sortlist.used):
13693 Don't truncate size to int.
13694 (record_overlay_string): Check for size-calculation overflow.
13695 (init_buffer_once): Check at compile-time, not run-time.
13697 2011-06-22 Jim Meyering <meyering@redhat.com>
13699 Don't leak an XBM-image-sized buffer
13700 * image.c (xbm_load): Free the image buffer after using it.
13702 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
13705 * composite.c (find_automatic_composition): Omit needless 'return 0;'
13706 that Sun C diagnosed.
13707 * fns.c (secure_hash): Fix pointer signedness issue.
13708 * intervals.c (static_offset_intervals): New function.
13709 (offset_intervals): Use it.
13711 2011-06-21 Leo Liu <sdl.web@gmail.com>
13714 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
13717 * fns.c (secure_hash): Rename from crypto_hash_function and change
13718 the first arg to accept symbols.
13719 (Fsecure_hash): New primitive.
13720 (syms_of_fns): New symbols.
13722 2011-06-20 Deniz Dogan <deniz@dogan.se>
13724 * process.c (Fset_process_buffer): Clarify return value in
13727 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
13729 * dispnew.c (add_window_display_history): Use BVAR.
13731 * xdisp.c (debug_method_add): Use BVAR.
13732 (check_window_end, dump_glyph_matrix, dump_glyph)
13733 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
13735 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
13738 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
13739 check till after the cache is created in init_frame_faces.
13741 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
13743 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
13745 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
13747 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
13748 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
13749 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
13751 Improve buffer-overflow checking (Bug#8873).
13752 * fileio.c (Finsert_file_contents):
13753 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
13754 Remove the old (too-loose) buffer overflow checks.
13755 They weren't needed, since make_gap checks for buffer overflow.
13756 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
13757 The old code merely checked for Emacs fixnum overflow, and relied
13758 on undefined (wraparound) behavior. The new code avoids undefined
13759 behavior, and also checks for ptrdiff_t and/or size_t overflow.
13761 * editfns.c (Finsert_char): Don't dump core with very negative counts.
13762 Tune. Don't use wider integers than needed. Don't use alloca.
13763 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
13765 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
13767 * insdel.c, lisp.h (buffer_overflow): New function.
13768 (insert_from_buffer_1, replace_range, replace_range_2):
13769 * insdel.c (make_gap_larger):
13770 * editfns.c (Finsert_char):
13771 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
13773 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
13775 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
13777 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
13779 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
13780 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
13782 * fileio.c: Don't assume EMACS_INT fits in off_t.
13783 (emacs_lseek): New static function.
13784 (Finsert_file_contents, Fwrite_region): Use it.
13785 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
13787 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
13789 * fns.c: Don't overflow int when computing a list length.
13790 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
13791 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
13792 truncation on 64-bit hosts. Check for QUIT every
13793 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
13794 faster and is responsive enough.
13795 (Flength): Report an error instead of overflowing an integer.
13796 (Fsafe_length): Return a float if the value is not representable
13797 as a fixnum. This shouldn't happen except in contrived situations.
13798 (Fnthcdr, Fsort): Don't assume list length fits in int.
13799 (Fcopy_sequence): Don't assume vector length fits in int.
13801 * alloc.c: Check that resized vectors' lengths fit in fixnums.
13802 (header_size, word_size): New constants.
13803 (allocate_vectorlike): Don't check size overflow here.
13804 (allocate_vector): Check it here instead, since this is the only
13805 caller of allocate_vectorlike that could cause overflow.
13806 Check that the new vector's length is representable as a fixnum.
13808 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
13809 The previous code was bogus. For example, next_almost_prime (32)
13810 returned 39, which is undesirable as it is a multiple of 3; and
13811 next_almost_prime (24) returned 25, which is a multiple of 5 so
13812 why was the code bothering to check for multiples of 7?
13814 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
13816 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
13818 Variadic C functions now count arguments with ptrdiff_t.
13819 This partly undoes my 2011-03-30 change, which replaced int with size_t.
13820 Back then I didn't know that the Emacs coding style prefers signed int.
13821 Also, in the meantime I found a few more instances where arguments
13822 were being counted with int, which may truncate counts on 64-bit
13823 machines, or EMACS_INT, which may be unnecessarily wide.
13824 * lisp.h (struct Lisp_Subr.function.aMANY)
13825 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
13826 Arg counts are now ptrdiff_t, not size_t.
13827 All variadic functions and their callers changed accordingly.
13828 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
13829 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
13830 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
13831 * callint.c (Fcall_interactively): Check arg count for overflow,
13832 to avoid potential buffer overrun. Use signed char, not 'int',
13833 for 'varies' array, so that we needn't bother to check its size
13834 calculation for overflow.
13835 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
13836 * eval.c (apply_lambda):
13837 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
13838 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
13839 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
13841 * callint.c (Fcall_interactively): Don't use index var as event count.
13843 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
13844 * mem-limits.h (SIZE): Remove; no longer used.
13846 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
13848 Remove unnecessary casts.
13849 * xterm.c (x_term_init):
13850 * xfns.c (x_set_border_pixel):
13851 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
13852 These aren't needed now that we assume ANSI C.
13854 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
13855 It's more likely to cause problems (due to unsigned overflow)
13858 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
13860 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
13862 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
13864 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
13866 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
13868 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
13870 GLYPH_CODE_FACE returns EMACS_INT, not int.
13871 * dispextern.h (merge_faces):
13872 * xfaces.c (merge_faces):
13873 * xdisp.c (get_next_display_element, next_element_from_display_vector):
13874 Don't assume EMACS_INT fits in int.
13876 * character.h (CHAR_VALID_P): Remove unused parameter.
13877 * fontset.c, lisp.h, xdisp.c: All uses changed.
13879 * editfns.c (Ftranslate_region_internal): Omit redundant test.
13881 * fns.c (concat): Minor tuning based on overflow analysis.
13882 This doesn't fix any bugs. Use int to hold character, instead
13883 of constantly refetching from Emacs object. Use XFASTINT, not
13884 XINT, for value known to be a character. Don't bother comparing
13885 a single byte to 0400, as it's always less.
13887 * floatfns.c (Fexpt):
13888 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
13890 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
13893 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
13895 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
13896 Without this fix, on a 64-bit host (aset S 0 4294967386) would
13897 incorrectly succeed when S was a string, because 4294967386 was
13898 truncated before it was used.
13900 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
13901 Otherwise, an out-of-range integer could cause undefined behavior
13904 * composite.c: Use int, not EMACS_INT, for characters.
13905 (fill_gstring_body, composition_compute_stop_pos): Use int, not
13906 EMACS_INT, for values that are known to be in character range.
13907 This doesn't fix any bugs but is the usual style inside Emacs and
13908 may generate better code on 32-bit machines.
13910 Make sure a 64-bit char is never passed to ENCODE_CHAR.
13911 This is for reasons similar to the recent CHAR_STRING fix.
13912 * charset.c (Fencode_char): Check that character arg is actually
13913 a character. Pass an int to ENCODE_CHAR.
13914 * charset.h (ENCODE_CHAR): Verify that the character argument is no
13915 wider than 'int', as a compile-time check to prevent future regressions
13918 * character.c (char_string): Remove unnecessary casts.
13920 Make sure a 64-bit char is never passed to CHAR_STRING.
13921 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
13922 by silently ignoring the top 32 bits, allowing some values
13923 that were far too large to be valid characters.
13924 * character.h: Include <verify.h>.
13925 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
13926 arguments are no wider than unsigned, as a compile-time check
13927 to prevent future regressions in this area.
13929 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
13930 (Fsubst_char_in_region):
13932 * xdisp.c (decode_mode_spec_coding):
13933 Adjust to CHAR_STRING's new requirement.
13934 * editfns.c (Finsert_char, Fsubst_char_in_region):
13935 * fns.c (concat): Check that character args are actually
13936 characters. Without this test, these functions did the wrong
13937 thing with wildly out-of-range values on 64-bit hosts.
13939 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
13940 These casts should not be needed on 32-bit hosts, either.
13941 * keyboard.c (read_char):
13942 * lread.c (Fload): Remove casts to unsigned.
13944 * lisp.h (UNSIGNED_CMP): New macro.
13945 This fixes comparison bugs on 64-bit hosts.
13946 (ASCII_CHAR_P): Use it.
13947 * casefiddle.c (casify_object):
13948 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
13949 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
13950 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
13951 * dispextern.h (FACE_FROM_ID):
13952 * keyboard.c (read_char): Use UNSIGNED_CMP.
13954 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
13955 not to EMACS_INT, to avoid GCC warning.
13957 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
13959 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
13960 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
13961 isn't needed on 32-bit machines.
13963 * buffer.c (Fgenerate_new_buffer_name):
13964 Use EMACS_INT for count, not int.
13965 (advance_to_char_boundary): Return EMACS_INT, not int.
13967 * data.c (Qcompiled_function): Now static.
13969 * window.c (window_body_lines): Now static.
13971 * image.c (gif_load): Rename local to avoid shadowing.
13973 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
13974 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
13975 * alloc.c (make_save_value): Integer argument is now of type
13976 ptrdiff_t, not int.
13977 (mark_object): Use ptrdiff_t, not int.
13978 * lisp.h (pD): New macro.
13979 * print.c (print_object): Use it.
13981 * alloc.c: Use EMACS_INT, not int, to count objects.
13982 (total_conses, total_markers, total_symbols, total_vector_size)
13983 (total_free_conses, total_free_markers, total_free_symbols)
13984 (total_free_floats, total_floats, total_free_intervals)
13985 (total_intervals, total_strings, total_free_strings):
13986 Now EMACS_INT, not int. All uses changed.
13987 (Fgarbage_collect): Compute overall total using a double, so that
13988 integer overflow is less likely to be a problem. Check for overflow
13989 when converting back to an integer.
13990 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
13991 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
13992 These were 'int' variables that could overflow on 64-bit hosts;
13993 they were never used, so remove them instead of repairing them.
13994 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
13995 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
13996 Previously, this ceilinged at INT_MAX, but that doesn't work on
13998 (allocate_pseudovector): Don't use EMACS_INT when int would do.
14000 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
14001 (allocate_vectorlike): Check for ptrdiff_t overflow.
14002 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
14003 when a (possibly-narrower) signed value would do just as well.
14004 We prefer using signed arithmetic, to avoid comparison confusion.
14006 * alloc.c: Catch some string size overflows that we were missing.
14007 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
14008 for convenience in STRING_BYTES_MAX.
14009 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
14010 The definition here is exact; the one in lisp.h was approximate.
14011 (allocate_string_data): Check for string overflow. This catches
14012 some instances we weren't catching before. Also, it catches
14013 size_t overflow on (unusual) hosts where SIZE_MAX <= min
14014 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
14015 and ptrdiff_t and EMACS_INT are both 64 bits.
14017 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
14018 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
14019 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
14021 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
14023 * alloc.c (Fmake_string): Check for out-of-range init.
14025 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
14027 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
14029 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
14031 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
14032 xg_get_default_scrollbar_width.
14034 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
14035 (int_gtk_range_get_value): Move to the scroll bar part of the file.
14036 (style_changed_cb): Call update_theme_scrollbar_width and call
14037 x_set_scroll_bar_default_width and xg_frame_set_char_size for
14038 all frames (Bug#8505).
14039 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
14040 Call gtk_window_set_resizable if HAVE_GTK3.

14042 and height if HAVE_GTK3 (Bug#8505).
14043 (scroll_bar_width_for_theme): New variable.
14044 (update_theme_scrollbar_width): New function.
14045 (xg_get_default_scrollbar_width): Move code to
14046 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
14047 (xg_initialize): Call update_theme_scrollbar_width.
14049 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
14051 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
14053 2011-06-12 Martin Rudalics <rudalics@gmx.at>
14055 * frame.c (make_frame): Call other_buffer_safely instead of
14058 * window.c (temp_output_buffer_show): Call display_buffer with
14059 second argument Vtemp_buffer_show_specifiers and reset latter
14060 immediately after the call.
14061 (Vtemp_buffer_show_specifiers): New variable.
14062 (auto_window_vscroll_p, next_screen_context_lines)
14063 (Vscroll_preserve_screen_position): Remove leading asterisks from

14246 Remove static from declaration of Qdelete_window, it's
14247 temporarily needed by Fbury_buffer.
14248 (replace_window): Don't assign orig_top_line and
14250 (Fdelete_window, delete_window): Remove. Window deletion is

14252 (window_loop): Remove DELETE_OTHER_WINDOWS case.
14253 Replace Fdelete_window calls with calls to Qdelete_window.
14254 (Fdelete_other_windows): Remove. Deleting other windows is

14627 value of a `display' property is a "replacing spec".
14628 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
14629 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

14659 * gnutls.c: Use Emacs's memory allocators.
14660 Without this change, the gnutls library would invoke malloc etc.
14661 directly, which causes problems on non-SYNC_INPUT hosts, and which
14662 runs afoul of improving memory_full behavior. (Bug#8761)
14663 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
14664 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
14665 xfree instead of the default malloc, realloc, free.
14666 (Fgnutls_boot): No need to check for memory allocation failure,
14667 since xmalloc does that for us.

14696 need to be updated by these changes.
14697 * fns.c (make_hash_table, maybe_resize_hash_table):
14698 Check for integer overflow with large hash tables.
14699 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
14700 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
14701 (SXHASH_REDUCE): New macro.
14702 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
14703 Use it instead of discarding useful hash info with large hash values.

14705 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
14706 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
14707 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
14708 Rewrite to use FIXNUM_BITS, as this simplifies things.
14709 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
14710 Adjust signatures to match updated version of code.
14711 (consing_since_gc): Now EMACS_INT, since a single hash table can
14712 use more than INT_MAX bytes.
14714 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
14716 Make it possible to build with GCC-4.6+ -O2 -flto.
14718 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
14720 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
14722 * minibuf.c (get_minibuffer, read_minibuf_unwind):
14723 Call minibuffer-inactive-mode.
14725 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
14727 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
14728 Update dependencies.
14730 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14732 * data.c (init_data): Remove code for UTS, this system is not
14735 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14737 Don't force ./temacs to start in terminal mode.
14739 * frame.c (make_initial_frame): Initialize faces in all cases, not
14740 only when CANNOT_DUMP is defined.
14741 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
14743 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14745 * dispnew.c (add_window_display_history): Use const for the string
14746 pointer. Remove declaration, not needed.
14748 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
14750 Use 'inline', not 'INLINE'.
14751 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
14752 * alloc.c, fontset.c (INLINE): Remove.
14753 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
14754 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
14755 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
14756 * gmalloc.c (register_heapinfo): Use inline unconditionally.
14757 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
14759 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14761 Make it possible to run ./temacs.
14763 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
14764 syms_of_callproc does the same thing. Remove test for
14765 "initialized", do it in the caller.
14766 * emacs.c (main): Avoid calling set_initial_environment when dumping.
14768 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
14770 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
14771 (read_minibuf): Use get_minibuffer.
14772 (syms_of_minibuf): Use DEFSYM.
14773 (Qmetadata): New var.
14774 * data.c (Qbuffer): Don't make it static.
14775 (syms_of_data): Use DEFSYM.
14777 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
14779 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
14780 (CCL_CODE_MIN): New macro.
14782 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
14784 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
14786 * eval.c (Qdebug): Now static.
14787 * lisp.h (Qdebug): Remove decl. This reverts a part of the
14788 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
14789 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
14791 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14793 * image.c: Various fixes to ImageMagick code comments.
14794 (Fimagemagick_types): Doc fix.
14796 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
14798 Minor fixes prompted by GCC 4.6.0 warnings.
14800 * xselect.c (converted_selections, conversion_fail_tag): Now static.
14802 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
14803 (x_clipboard_manager_save_all): Move extern decl to ...
14804 * xterm.h: ... here, so that it can be checked for consistency.
14806 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14808 * xselect.c (x_clipboard_manager_save_frame)
14809 (x_clipboard_manager_save_all): New functions.
14810 (Fx_clipboard_manager_save): Lisp function deleted.
14812 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
14813 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
14815 * xterm.h: Update prototype.
14817 2011-05-28 William Xu <william.xwl@gmail.com>
14819 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
14820 exiting (Bug#8239).
14822 2011-05-28 Jim Meyering <meyering@redhat.com>
14824 Avoid a sign-extension bug in crypto_hash_function.
14825 * fns.c (to_uchar): Define.
14826 (crypto_hash_function): Use it to convert some newly-signed
14827 variables to unsigned, to avoid sign-extension bugs. For example,
14828 without this change, (md5 "truc") would evaluate to
14829 45723a2aff78ff4fff7fff1114760e62 rather than the expected
14830 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
14831 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
14833 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14835 Integer overflow fixes.
14837 * dbusbind.c: Serial number integer overflow fixes.
14838 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
14839 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
14840 to hold a serial number that is too large for a fixnum.
14841 (Fdbus_method_return_internal, Fdbus_method_error_internal):
14842 Check for serial numbers out of range. Decode any serial number
14843 that was so large that it became a float. (Bug#8722)
14845 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
14846 (Fdbus_call_method, Fdbus_call_method_asynchronously):
14847 Use XFASTINT rather than XUINT when numbers are nonnegative.
14848 (xd_append_arg, Fdbus_method_return_internal):
14849 (Fdbus_method_error_internal): Likewise. Also, for unsigned
14850 arguments, check that Lisp number is nonnegative, rather than
14851 silently wrapping negative numbers around. (Bug#8722)
14852 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
14855 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
14857 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
14859 ccl: Add integer overflow checks.
14860 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
14861 (IN_INT_RANGE): New macros.
14862 (ccl_driver): Use them to check for integer overflow when
14863 decoding a CCL program. Many of the new checks are whether XINT (x)
14864 fits in int; it doesn't always, on 64-bit hosts. The new version
14865 doesn't catch all possible integer overflows, but it's an
14866 improvement. (Bug#8719)
14868 * alloc.c (make_event_array): Use XINT, not XUINT.
14869 There's no need for unsigned here.
14871 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
14872 This follows up to the 2011-05-06 change that substituted uintptr_t
14873 for EMACS_INT. This case wasn't caught back then.
14875 Rework Fformat to avoid integer overflow issues.
14876 * editfns.c: Include <float.h> unconditionally, as it's everywhere
14877 now (part of C89). Include <verify.h>.
14878 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
14879 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
14880 (Fformat): Avoid the prepass trying to compute sizes; it was only
14881 approximate and thus did not catch overflow reliably. Instead, walk
14882 through the format just once, formatting and computing sizes as we go,
14883 checking for integer overflow at every step, and allocating a larger
14884 buffer as needed. Keep track separately whether the format is
14885 multibyte. Keep only the most-recently calculated precision, rather
14886 than them all. Record whether each argument has been converted to
14887 string. Use EMACS_INT, not int, for byte and char and arg counts.
14888 Support field widths and precisions larger than INT_MAX. Avoid
14889 sprintf's undefined behavior with conversion specifications such as %#d
14890 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
14891 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
14892 formatting out-of-range floating point numbers with int
14893 formats. (Bug#8668)
14895 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
14897 * data.c: Avoid integer truncation in expressions involving floats.
14898 * data.c: Include <intprops.h>.
14899 (arith_driver): When there's an integer overflow in an expression
14900 involving floating point, convert the integers to floating point
14901 so that the resulting value does not suffer from catastrophic
14902 integer truncation. For example, on a 64-bit host (* 4
14903 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
14904 Do not rely on undefined behavior after integer overflow.
14906 merge count_size_as_multibyte, parse_str_to_multibyte
14907 * character.c, character.h (count_size_as_multibyte):
14908 Rename from parse_str_to_multibyte; all uses changed.
14909 Check for integer overflow.
14910 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
14911 since it's now a duplicate of the other. This is more of
14912 a character than a buffer op, so better that it's in character.c.
14913 * fns.c, print.c: Adjust to above changes.
14915 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
14917 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
14919 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14921 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14922 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
14923 (x_clipboard_manager_save): Now static.
14924 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
14926 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14927 (crypto_hash_function): Now static.
14928 Fix pointer signedness problems. Avoid unnecessary initializations.
14930 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
14932 * termhooks.h (Vselection_alist): Make it terminal-local.
14934 * terminal.c (create_terminal): Initialize it.
14936 * xselect.c: Support for clipboard managers.
14937 (Vselection_alist): Move to termhooks.h as terminal-local var.
14938 (LOCAL_SELECTION): New macro.
14939 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
14940 (symbol_to_x_atom): Remove gratuitous arg.
14941 (x_handle_selection_request, lisp_data_to_selection_data)
14942 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
14943 (x_own_selection, x_get_local_selection, x_convert_selection):
14944 New arg, specifying work frame. Use terminal-local Vselection_alist.
14945 (some_frame_on_display): Delete unused function.
14946 (Fx_own_selection_internal, Fx_get_selection_internal)
14947 (Fx_disown_selection_internal, Fx_selection_owner_p)
14948 (Fx_selection_exists_p): New optional frame arg.
14949 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
14950 (x_handle_selection_clear): Don't treat other terminals with the
14951 same keyboard specially. Use the terminal-local Vselection_alist.
14952 (x_clear_frame_selections): Use Frun_hook_with_args.
14954 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
14956 * xterm.h: Add support for those atoms.
14958 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
14960 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
14961 (converted_selections, conversion_fail_tag): New global variables.
14962 (x_selection_request_lisp_error): Free the above.
14963 (x_get_local_selection): Remove unnecessary code.
14964 (x_reply_selection_request): Args changed; handle arbitrary array
14965 of converted selections stored in converted_selections.
14966 Separate the XChangeProperty and SelectionNotify steps.
14967 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
14968 (x_convert_selection): New function.
14969 (x_handle_selection_event): Simplify.
14970 (x_get_foreign_selection): Don't ignore incoming requests while
14971 waiting for an answer; this will fail when we implement
14972 SAVE_TARGETS, and seems unnecessary anyway.
14973 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
14974 (Vx_sent_selection_functions): Doc fix.
14976 2011-05-26 Leo Liu <sdl.web@gmail.com>
14978 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
14980 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14982 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
14984 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
14985 for fringe update if it has periodic bitmap.
14986 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
14987 and fringe_bitmap_periodic_p.
14989 * fringe.c (get_fringe_bitmap_data): New function.
14990 (draw_fringe_bitmap_1, update_window_fringes): Use it.
14991 (update_window_fringes): Record periodicity of fringe bitmap in glyph
14992 row. Mark glyph row for fringe update if periodicity changed.
14994 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
14995 for fringe update unless it has periodic bitmap.
14997 2011-05-25 Kenichi Handa <handa@m17n.org>
14999 * xdisp.c (get_next_display_element): Set correct it->face_id for
15000 a static composition.
15002 2011-05-24 Leo Liu <sdl.web@gmail.com>
15005 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
15007 * fns.c (crypto_hash_function, Fsha1): New function.
15008 (Fmd5): Use crypto_hash_function.
15009 (syms_of_fns): Add Ssha1.
15011 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
15013 * gnutls.c: Remove unused macros.
15014 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
15015 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
15016 Remove macros that are defined and never used.
15017 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
15019 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
15021 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
15022 (Fx_get_selection_internal): Minor cleanup.
15023 (Fx_own_selection_internal): Rename arguments for consistency with
15026 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
15028 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
15030 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
15032 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
15034 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15036 * dispnew.c (scrolling_window): Don't exclude the case that the
15037 last enabled row in the desired matrix touches the bottom boundary.
15039 2011-05-21 Glenn Morris <rgm@gnu.org>
15041 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
15042 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
15043 and add some more files.
15045 2011-05-20 Eli Zaretskii <eliz@gnu.org>
15047 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
15048 report_file_error introduced by the change from 2011-05-07.
15050 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
15052 * systime.h (Time): Define only if emacs is defined.
15053 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
15054 where the include path doesn't have X11/X.h by default. See
15055 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
15057 2011-05-20 Kenichi Handa <handa@m17n.org>
15059 * composite.c (find_automatic_composition): Fix previous change.
15061 2011-05-20 Glenn Morris <rgm@gnu.org>
15063 * lisp.mk: New file, split from Makefile.in.
15064 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
15065 (shortlisp): Remove.
15066 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
15068 2011-05-19 Glenn Morris <rgm@gnu.org>
15070 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
15071 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
15072 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
15073 (lisp): Set the order to that of loadup.el.
15074 (shortlisp): Make it a copy of $lisp.
15075 (SOME_MACHINE_LISP): Remove.
15076 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
15077 Use just $shortlisp, not $SOME_MACHINE_LISP too.
15079 2011-05-18 Kenichi Handa <handa@m17n.org>
15081 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
15082 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
15083 (find_automatic_composition): Mostly rewrite for efficiency.
15085 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
15087 * makefile.w32-in: Update dependencies.
15089 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
15091 * menu.c: Include limits.h (fixes the MS-Windows build broken by
15092 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
15094 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
15096 Fix some integer overflow issues, such as string length overflow.
15098 * insdel.c (count_size_as_multibyte): Check for string overflow.
15100 * character.c (lisp_string_width): Check for string overflow.
15101 Use EMACS_INT, not int, for string indexes and lengths; in
15102 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
15103 the resulting string length overflows an EMACS_INT; instead,
15104 report a string overflow if no precision given. When checking for
15105 precision exhaustion, use a check that cannot possibly have
15106 integer overflow. (Bug#8675)
15107 * character.h (lisp_string_width): Adjust to new signature.
15109 * alloc.c (string_overflow): New function.
15110 (Fmake_string): Use it. This doesn't change behavior, but saves
15111 a few bytes and will simplify future changes.
15112 * character.c (string_escape_byte8): Likewise.
15113 * lisp.h (string_overflow): New decl.
15115 Fixups, following up to the user-interface timestamp change.
15116 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
15117 for UI timestamps, instead of unsigned long.
15118 * msdos.c (mouse_get_pos): Likewise.
15119 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
15120 * w32gui.h (Time): Define by including "systime.h" rather than by
15121 declaring it ourselves. (Bug#8664)
15123 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
15124 * image.c (clear_image_cache): Likewise.
15126 * term.c (term_mouse_position): Don't assume time_t wraparound.
15128 Be more systematic about user-interface timestamps.
15129 Before, the code sometimes used 'Time', sometimes 'unsigned long',
15130 and sometimes 'EMACS_UINT', to represent these timestamps.
15131 This change causes it to use 'Time' uniformly, as that's what X uses.
15132 This makes the code easier to follow, and makes it easier to catch
15133 integer overflow bugs such as Bug#8664.
15134 * frame.c (Fmouse_position, Fmouse_pixel_position):
15135 Use Time, not unsigned long, for user-interface timestamps.
15136 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
15137 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
15138 * keyboard.h (last_event_timestamp): Likewise.
15139 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
15140 * menu.h (xmenu_show): Likewise.
15141 * term.c (term_mouse_position): Likewise.
15142 * termhooks.h (struct input_event.timestamp): Likewise.
15143 (struct terminal.mouse_position_hook): Likewise.
15144 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
15145 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
15146 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
15147 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
15148 what it was before.
15149 * menu.h, termhooks.h: Include "systime.h", for Time.
15151 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
15152 Don't assume that the difference between two unsigned long values
15153 can fit into an integer. At this point, we know button_down_time
15154 <= event->timestamp, so the difference must be nonnegative, so
15155 there's no need to cast the result if double-click-time is
15156 nonnegative, as it should be; check that it's nonnegative, just in
15157 case. This bug is triggered when events are more than 2**31 ms
15158 apart (about 25 days). (Bug#8664)
15160 * xselect.c (last_event_timestamp): Remove duplicate decl.
15161 (x_own_selection): Remove needless cast to unsigned long.
15163 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
15164 that always fit in int. Use a sentinel instead of a counter, to
15165 avoid a temp and to allay GCC's concerns about possible int overflow.
15166 * frame.h (struct frame): Use int for menu_bar_items_used
15167 instead of EMACS_INT, since it always fits in int.
15169 * menu.c (grow_menu_items): Check for int overflow.
15171 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
15173 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
15174 Before, the code was not consistent. These values cannot exceed
15175 2**31 - 1 so there's no need to make them unsigned.
15176 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
15177 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
15178 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
15180 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
15182 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
15183 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
15184 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
15185 presumably because the widths might not match.
15187 * window.c (size_window): Avoid needless test at loop start.
15189 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
15191 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
15193 2011-05-12 Drew Adams <drew.adams@oracle.com>
15195 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
15197 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15199 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
15200 `width' to `bar_area_x' and `bar_area_width', respectively.
15201 (x_scroll_run): Take account of fringe background extension.
15203 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
15204 Rename local vars `left' and `width' to `bar_area_x' and
15205 `bar_area_width', respectively.
15206 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
15207 background extension.
15209 2011-05-10 Jim Meyering <meyering@redhat.com>
15211 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
15213 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
15215 * image.c (Finit_image_library): Return t for built-in image types,
15216 like pbm and xbm. (Bug#8640)
15218 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
15220 * w32menu.c (set_frame_menubar): Fix submenu allocation.
15222 2011-05-07 Eli Zaretskii <eliz@gnu.org>
15224 * w32console.c (Fset_screen_color): Doc fix.
15225 (Fget_screen_color): New function.
15226 (syms_of_ntterm): Defsubr it.
15228 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
15229 unlink the temporary file if Fcall_process didn't create it in the
15231 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
15232 child process will be redirected to a file specified with `:file'.
15233 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
15234 cue to call_process_cleanup not to close that handle.
15236 2011-05-07 Ben Key <bkey76@gmail.com>
15238 * makefile.w32-in: The bootstrap-temacs rule now makes use of
15239 one of two shell specific rules, either bootstrap-temacs-CMD or
15240 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
15241 to the previous implementation of the bootstrap-temacs rule.
15242 The bootstrap-temacs-CMD rule is similar to the previous
15243 implementation of the bootstrap-temacs rule except that it
15244 makes use of the ESC_CFLAGS variable instead of the CFLAGS
15247 These changes, along with some changes to nt/configure.bat,
15248 nt/gmake.defs, and nt/nmake.defs, are required to extend my
15249 earlier fix to add support for --cflags and --ldflags options
15250 that include quotes so that it works whether make uses cmd or
15253 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
15255 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
15256 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
15258 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
15259 a string. Handle both cases.
15260 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
15261 (Fdbus_register_method): Use Qinvalid_function.
15263 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
15265 * makefile.w32-in: Update dependencies.
15266 (LISP_H): Add inttypes.h and stdin.h.
15267 (PROCESS_H): Add unistd.h.
15269 2011-05-06 Eli Zaretskii <eliz@gnu.org>
15271 * lread.c: Include limits.h (fixes the MS-Windows build broken by
15272 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
15274 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
15276 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
15278 * term.c (vfatal): Remove stray call to va_end.
15279 It's not needed and the C Standard doesn't allow it here anyway.
15281 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
15282 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
15284 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
15287 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
15289 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15291 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
15293 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
15295 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
15297 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
15298 * charset.c (Fdefine_charset_internal): Don't initialize
15299 charset.code_space[15]. The value was garbage, on hosts with
15300 32-bit int (Bug#8600).
15302 * lread.c (read_integer): Be more consistent with string-to-number.
15303 Use string_to_number to do the actual conversion; this avoids
15304 rounding errors and fixes some other screwups. Without this fix,
15305 for example, #x1fffffffffffffff was misread as -2305843009213693952.
15306 (digit_to_number): Move earlier, for benefit of read_integer.
15307 Return -1 if the digit is out of range for the base, -2 if it is
15308 not a digit in any supported base. (Bug#8602)
15310 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
15312 * dispnew.c (scrolling_window): Return 1 if we scrolled,
15313 to match comment at start of function. This also removes a
15314 GCC warning about overflow in a 32+64-bit port.
15316 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
15318 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
15319 Reported by Stefan Monnier in
15320 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
15321 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
15322 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
15324 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
15325 (EMACS_UINTPTR): Likewise, with uintptr_t.
15327 * lisp.h: Prefer 64-bit EMACS_INT if available.
15328 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
15329 on 32-bit hosts that have 64-bit int, so that they can access
15331 However, temporarily disable this change unless the temporary
15332 symbol WIDE_EMACS_INT is defined.
15334 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
15336 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
15337 This removes an assumption that EMACS_INT and long are the same
15338 width as pointers. The assumption is true for Emacs porting targets
15339 now, but we want to make other targets possible.
15340 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
15341 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
15342 In the rest of the code, change types of integers that hold casted
15343 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
15344 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
15345 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
15346 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
15347 No need to cast type when ORing.
15348 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
15349 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
15350 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
15351 assume EMACS_INT is the same width as char *.
15352 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
15353 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
15354 Remove no-longer-needed casts.
15355 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
15356 (xg_tool_bar_help_callback, xg_make_tool_item):
15357 Use EMACS_INTPTR to hold an integer
15358 that will be cast to void *; this can avoid a GCC warning
15359 if EMACS_INT is not the same width as void *.
15360 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
15361 * xdisp.c (display_echo_area_1, resize_mini_window_1):
15362 (current_message_1, set_message_1):
15363 Use a local to convert to proper width without a cast.
15364 * xmenu.c (dialog_selection_callback): Likewise.
15366 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
15367 Also, don't assume VALBITS / RAND_BITS is less than 5,
15368 and don't rely on undefined behavior when shifting a 1 left into
15370 * lisp.h (get_random): Change signature to match.
15372 * lread.c (hash_string): Use size_t, not int, for hash computation.
15373 Normally we prefer signed values; but hashing is special, because
15374 it's better to use unsigned division on hash table sizes so that
15375 the remainder is nonnegative. Also, size_t is the natural width
15376 for hashing into memory. The previous code used 'int', which doesn't
15377 retain enough info to hash well into very large tables.
15378 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
15380 * dbusbind.c: Don't possibly lose pointer info when converting.
15381 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
15382 Use XPNTR rather than XHASH, so that the high-order bits of
15383 the pointer aren't lost when converting through void *.
15385 * eval.c (Fautoload): Don't double-shift a pointer.
15387 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
15389 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
15391 * gnutls.c (DEF_GNUTLS_FN):
15392 * image.c (DEF_IMGLIB_FN): Make function pointers static.
15394 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
15396 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
15399 2011-05-05 Eli Zaretskii <eliz@gnu.org>
15401 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
15402 New version that can reserve upto 2GB of heap space.
15404 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
15406 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
15408 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
15410 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
15411 `gnutls_certificate_set_x509_key_file'.
15413 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
15415 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
15416 Update dependencies.
15418 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15420 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
15421 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
15422 Remove unused parameter `fildes'.
15423 * process.c (read_process_output, send_process): Don't pass it.
15425 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15427 Fix previous change: the library cache is defined in w32.c.
15428 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
15429 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
15431 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15433 Implement dynamic loading of GnuTLS on Windows.
15435 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
15436 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
15437 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
15440 * gnutls.c (Qgnutls_dll): Define.
15441 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
15442 (gnutls_*): Declare function pointers.
15443 (init_gnutls_functions): New function to initialize function pointers.
15444 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
15445 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
15446 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
15447 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
15448 (emacs_gnutls_write, emacs_gnutls_read)
15449 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
15450 (Fgnutls_available_p): New function.
15451 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
15452 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
15453 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
15455 * image.c: Include w32.h.
15456 (Vimage_type_cache): Delete.
15457 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
15458 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
15459 (w32_delayed_load): Move to w32.c.
15461 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
15463 * w32.c (QCloaded_from, Vlibrary_cache): Define.
15464 (w32_delayed_load): Move from image.c. When loading a library, record
15465 its filename in the :loaded-from property of the library id.
15466 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
15467 Initialize and staticpro them.
15468 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
15470 * process.c: Include lisp.h before w32.h, not after.
15471 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
15472 instead of gnutls_record_check_pending.
15474 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
15476 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
15478 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
15479 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
15482 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
15484 * xterm.c (x_set_frame_alpha): Do not set property on anything
15485 else than FRAME_X_OUTER_WINDOW (Bug#8608).

15505 * callproc.c: Indentation fixup.
15507 * sysdep.c (wait_for_termination_1): Make static.
15508 (wait_for_termination, interruptible_wait_for_termination):
15509 Move after wait_for_termination_1.
15511 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
15513 * sysdep.c (interruptible_wait_for_termination): New function
15514 which is like wait_for_termination, but allows keyboard
15517 * callproc.c (Fcall_process): Add (:file "file") as an option for
15519 (Fcall_process_region): Ditto.
15521 2011-04-30 Eli Zaretskii <eliz@gnu.org>
15523 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
15524 rather than `XVECTOR (FOO)->size'.
15526 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
15527 inttypes.h, as a gnulib replacement is used if it not available in
15530 2011-04-21 Eli Zaretskii <eliz@gnu.org>
15532 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
15533 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
15534 of MOST_POSITIVE_FIXNUM. (Bug#8528)
15536 * coding.c (coding_alloc_by_realloc): Error out if destination
15537 will grow beyond MOST_POSITIVE_FIXNUM.
15538 (decode_coding_emacs_mule): Abort if there isn't enough place in
15539 charbuf for the composition carryover bytes. Reserve an extra

15547 aborting when %lld or %lll format is passed.
15548 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
15549 %llo or %llx format is passed. (Bug#8545)
15551 * window.c (window_scroll_line_based): Use a marker instead of
15552 simple variables to record original value of point. (Bug#7952)
15554 * doprnt.c (doprnt): Fix the case where a multibyte sequence
15555 produced by %s or %c overflows available buffer space. (Bug#8545)
15557 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
15559 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
15560 (SIZE_MAX): Move defn after all includes, as they might #define it.
15562 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15564 * w32.c (init_environment): Warn about defaulting HOME to C:\.

15582 (Fx_window_property): #if-0 the whole functions, not just the bodies.
15584 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15586 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
15588 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
15590 * makefile.w32-in: Update dependencies.
15592 2011-04-27 Eli Zaretskii <eliz@gnu.org>
15594 Improve `doprnt' and its usage. (Bug#8545)
15595 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
15596 `format_end'. Remove support for %l as a conversion specifier.
15597 Don't use xrealloc. Improve diagnostics when the %l size modifier
15598 is used. Update the commentary.
15600 * eval.c (verror): Simplify calculation of size_t.
15602 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
15605 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
15607 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
15610 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15612 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
15613 This makes this file independent of the recent pseudovector change.
15615 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
15617 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
15619 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
15620 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
15621 Remove unused local.
15622 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
15624 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
15625 GCC 4.6.0 optimizes based on type-based alias analysis.
15626 For example, if b is of type struct buffer * and v of type struct
15627 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
15628 != &v->size, and therefore "v->size = 1; b->size = 2; return
15629 v->size;" must therefore return 1. This assumption is incorrect
15630 for Emacs, since it type-puns struct Lisp_Vector * with many other
15631 types. To fix this problem, this patch adds a new type struct
15632 vectorlike_header that documents the constraints on layout of vectors
15633 and pseudovectors, and helps optimizing compilers not get fooled
15634 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
15635 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
15636 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
15638 (XSETPVECTYPE): Rewrite in terms of new macro.
15639 (XSETPVECTYPESIZE): New macro, specifying both type and size.
15640 This is a bit clearer, and further avoids the possibility of
15641 undesirable aliasing.
15642 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
15643 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
15644 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
15645 since Lisp_Subr is a special case (no "next" field).
15646 (ASIZE): Now uses header.size rather than size.
15647 All previous uses of XVECTOR (foo)->size replaced to use this macro,
15648 to avoid the hassle of writing XVECTOR (foo)->header.size.
15649 (struct vectorlike_header): New type.
15650 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
15651 object, to help avoid aliasing.
15652 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
15653 (SUBRP): Likewise, since Lisp_Subr is a special case.
15654 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
15655 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
15656 (struct Lisp_Hash_Table): Combine first two members into a single
15657 struct vectorlike_header member. All uses of "size" and "next" members
15658 changed to be "header.size" and "header.next".
15659 * buffer.h (struct buffer): Likewise.
15660 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
15661 * frame.h (struct frame): Likewise.
15662 * process.h (struct Lisp_Process): Likewise.
15663 * termhooks.h (struct terminal): Likewise.
15664 * window.c (struct save_window_data, struct saved_window): Likewise.
15665 * window.h (struct window): Likewise.
15666 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
15667 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
15668 * buffer.c (init_buffer_once): Likewise.
15669 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
15671 * process.c (Fformat_network_address): Use local var for size,
15674 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
15676 Make the Lisp reader and string-to-float more consistent (Bug#8525)
15677 * data.c (atof): Remove decl; no longer used or needed.
15678 (digit_to_number): Move to lread.c.
15679 (Fstring_to_number): Use new string_to_number function, to be
15680 consistent with how the Lisp reader treats infinities and NaNs.
15681 Do not assume that floating-point numbers represent EMACS_INT
15682 without losing information; this is not true on most 64-bit hosts.
15683 Avoid double-rounding errors, by insisting on integers when
15684 parsing non-base-10 numbers, as the documentation specifies.
15685 * lisp.h (string_to_number): New decl, replacing ...
15686 (isfloat_string): Remove.
15687 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
15688 (read1): Do not accept +. and -. as integers; this
15689 appears to have been a coding error. Similarly, do not accept
15690 strings like +-1e0 as floating point numbers. Do not report
15691 overflow for integer overflows unless the base is not 10 which
15692 means we have no simple and reliable way to continue.
15693 Break out the floating-point parsing into a new
15694 function string_to_number, so that Fstring_to_number parses
15695 floating point numbers consistently with the Lisp reader.
15696 (digit_to_number): Move here from data.c. Make it static inline.
15697 (E_CHAR, EXP_INT): Remove, replacing with ...
15698 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
15699 (string_to_number): New function, replacing isfloat_string.
15700 This function checks for valid syntax and produces the resulting
15701 Lisp float number too. Rework it so that string-to-number
15702 no longer mishandles examples like "1.0e+". Use strtoumax,
15703 so that overflow for non-base-10 numbers is reported only when
15704 there's no portable and simple way to convert to floating point.
15706 * textprop.c (set_text_properties_1): Rewrite for clarity,
15707 and to avoid GCC warning about integer overflow.
15709 * intervals.h (struct interval): Use EMACS_INT for members
15710 where EMACS_UINT might cause problems. See
15711 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
15712 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
15713 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
15715 (offset_intervals): Tell GCC not to worry about length overflow
15716 when negating a negative length.
15718 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
15719 (overrun_check_free): Likewise.
15721 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
15722 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
15725 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15726 (gnutls_make_error): Rename local to avoid shadowing.
15727 (gnutls_emacs_global_deinit): ifdef out; not used.
15728 (Fgnutls_boot): Use const for pointer to readonly storage.
15729 Comment out unused local. Fix pointer signedness problems.
15731 * lread.c (openp): Don't stuff size_t into an 'int'.
15732 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
15733 about possible signed overflow.
15735 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15736 (GDK_KEY_g): Don't define if already defined.
15737 (xg_prepare_tooltip): Avoid pointer signedness problem.
15738 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
15740 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
15741 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
15743 * xfns.c (Fx_window_property): Simplify a bit,
15744 to make a bit faster and to avoid GCC 4.6.0 warning.
15745 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
15747 * fns.c (internal_equal): Don't assume size_t fits in int.
15749 * alloc.c (compact_small_strings): Tighten assertion a little.
15751 Replace pEd with more-general pI, and fix some printf arg casts.
15752 * lisp.h (pI): New macro, generalizing old pEd macro to other
15753 conversion specifiers. For example, use "...%"pI"d..." rather
15754 than "...%"pEd"...".
15755 (pEd): Remove. All uses replaced with similar uses of pI.
15756 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
15757 * alloc.c (check_pure_size): Don't overflow by converting size to int.
15758 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
15759 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
15760 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
15761 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
15762 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
15764 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
15765 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
15766 * print.c (safe_debug_print, print_object): Likewise.
15767 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
15769 Use pI instead of if-then-else-abort. Use %p to avoid casts,
15770 avoiding the 0 flag, which is not portable.
15771 * process.c (Fmake_network_process): Use pI to avoid cast.
15772 * region-cache.c (pp_cache): Likewise.
15773 * xdisp.c (decode_mode_spec): Likewise.
15774 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
15775 behavior on 64-bit hosts with printf arg.
15776 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
15777 (x_stop_queuing_selection_requests): Likewise.
15778 (x_get_window_property): Don't truncate byte count to an 'int'
15781 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
15782 here, since it parses constructs like leading '-' and spaces,
15783 which are not wanted; and it overflows with large numbers.
15784 Instead, simply match F[0-9]+, which is what is wanted anyway.
15786 * alloc.c: Remove unportable assumptions about struct layout.
15787 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
15788 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
15789 (allocate_vectorlike, make_pure_vector): Use the new macros,
15790 plus offsetof, to remove unportable assumptions about struct layout.
15791 These assumptions hold on all porting targets that I know of, but
15792 they are not guaranteed, they're easy to remove, and removing them
15793 makes further changes easier.
15795 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
15796 This doesn't fix a bug but makes the code clearer.
15797 (string_overrun_cookie): Now const. Use initializers that
15798 don't formally overflow signed char, to avoid warnings.
15799 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
15800 can cause Emacs to crash when string overrun checking is enabled.
15801 (allocate_buffer): Don't assume sizeof (struct buffer) is a
15802 multiple of sizeof (EMACS_INT); it need not be, if
15803 alignof(EMACS_INT) < sizeof (EMACS_INT).
15804 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
15806 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

15810 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
15812 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
15813 supposed to be handshaking. (Bug#8556)
15814 Reported by Paul Eggert <eggert@cs.ucla.edu>.
15816 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
15818 * lisp.h (Qdebug): List symbol.
15819 * eval.c (Qdebug): Restore global linkage.

15821 (handle_user_signal): Break into debugger when debug-on-event
15822 matches the current signal symbol.
15824 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
15826 * alloc.c (check_sblock, check_string_bytes)
15827 (check_string_free_list): Convert to standard C.
15829 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
15831 * w32.c (emacs_gnutls_push): Fix typo.
15833 2011-04-25 Eli Zaretskii <eliz@gnu.org>
15835 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
15836 "cast to pointer from integer of different size".
15838 Improve doprnt and its use in verror. (Bug#8545)
15839 * doprnt.c (doprnt): Document the set of format control sequences
15840 supported by the function. Use SAFE_ALLOCA instead of always
15843 * eval.c (verror): Don't limit the buffer size at size_max-1, that
15844 is one byte too soon. Don't use xrealloc; instead xfree and
15847 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
15849 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
15852 * gnutls.c: Renamed global_initialized to
15853 gnutls_global_initialized. Added internals for the
15854 :verify-hostname-error, :verify-error, and :verify-flags
15855 parameters of `gnutls-boot' and documented those parameters in the
15856 docstring. Start callback support.
15857 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
15858 unless a fatal error occurred. Call gnutls_alert_send_appropriate
15859 on error. Return error code.
15860 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
15861 (emacs_gnutls_read): Likewise.
15862 (Fgnutls_boot): Return handshake error code.
15863 (emacs_gnutls_handle_error): New function.
15864 (wsaerror_to_errno): Likewise.

15875 buffered some data internally if no FDs are set for TLS
15878 * makefile.w32-in (OBJ2): Add gnutls.$(O).

15926 <char-direction-table>: Deleted.
15928 2011-04-23 Eli Zaretskii <eliz@gnu.org>
15930 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
15931 * doprnt.c: Include limits.h.
15932 (SIZE_MAX): New macro.
15933 (doprnt): Return a size_t value. 2nd arg is now size_t.
15934 Many local variables are now size_t instead of int or unsigned.
15935 Improve overflow protection. Support `l' modifier for integer
15936 conversions. Support %l conversion. Don't assume an EMACS_INT
15937 argument for integer conversions and for %c.
15939 * lisp.h (doprnt): Restore prototype.
15941 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
15942 $(SRC)/character.h.
15944 * Makefile.in (base_obj): Add back doprnt.o.
15946 * deps.mk (doprnt.o): Add back prerequisites.
15947 (callint.o): Depend on character.h.
15949 * eval.c (internal_lisp_condition_case): Include the handler
15950 representation in the error message.
15951 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
15952 when breaking from the loop.
15954 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
15956 * callint.c (Fcall_interactively): When displaying error message
15957 about invalid control letter, pass the character's codepoint, not
15958 a pointer to its multibyte form. Improve display of the character
15959 in octal and display also its hex code.
15961 * character.c (char_string): Use %x to display the (unsigned)
15962 codepoint of an invalid character, to avoid displaying a bogus
15965 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
15966 `error', not SYMBOL_NAME itself.
15968 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
15969 character arguments to `error'.
15971 * charset.c (check_iso_charset_parameter): Fix incorrect argument
15972 to `error' in error message about FINAL_CHAR argument. Make sure
15973 FINAL_CHAR is a character, and use %c when it is passed as
15974 argument to `error'.
15976 2011-04-23 Eli Zaretskii <eliz@gnu.org>

16163 * nsfont.m: Fixed bugs in ns_get_family and
16164 ns_descriptor_to_entity that were caused by using free to
16165 deallocate memory blocks that were allocated by xmalloc (via
16166 xstrdup). This caused Emacs to crash when compiled with
16167 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
16168 --enable-checking=xmallocoverrun). xfree is now used to
16169 deallocate these memory blocks.

16186 (emacs_read, emacs_write): Use it.
16187 * process.c (send_process): Adjust to the new signatures of
16188 emacs_write and emacs_gnutls_write. Do not attempt to store

16517 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
16518 * lisp.h: Remove these decls.
16520 * buffer.c (buffer_count): Remove unused var.
16522 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
16523 so that it's not optimized away.
16524 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
16525 * dispextern.h (bidi_dump_cached_states): Remove, since it's
16526 exported only to the debugger.
16528 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
16529 * atimer.h (run_all_atimers): Remove; not exported.
16531 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
16532 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
16533 was inaccessible from Lisp.
16534 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
16535 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
16537 alloc.c: Import and export fewer symbols, and remove unused items.
16538 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
16540 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
16541 it's not optimized away by whole-program optimization.
16542 (message_enable_multibyte, free_misc): Remove.
16543 (catchlist, handlerlist, mark_backtrace):
16544 Declare only if BYTE_MARK_STACK.
16545 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
16546 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.

16553 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
16554 (mark_backtrace): Define only if BYTE_MARK_STACK.
16555 * xdisp.c (message_enable_multibyte): Now static.
16557 Declare Lisp_Object Q* variables to be 'static' if not exported.
16558 This makes it easier for human readers (and static analyzers)
16559 to see whether these variables are used from other modules.
16560 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
16561 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
16562 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

16565 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
16566 * xmenu.c, xselect.c:
16567 Declare Q* vars static if they are not used in other modules.

16569 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
16570 Remove decls of unexported vars.
16571 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
16573 * lisp.h (DEFINE_FUNC): Make sname 'static'.
16575 Make Emacs functions such as Fatom 'static' by default.
16576 This makes it easier for human readers (and static analyzers)
16577 to see whether these functions can be called from other modules.
16578 DEFUN now defines a static function. To make the function external
16579 so that it can be used in other C modules, use the new macro DEFUE.
16580 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
16581 (Finit_image_library):
16582 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
16583 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
16584 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
16585 Remove decls, since these functions are now static.
16586 (Funintern, Fget_internal_run_time): New decls, since these functions
16587 were already external.
16589 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
16590 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

16596 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
16597 Mark functions with DEFUE instead of DEFUN,
16598 if they are used in other modules.
16599 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
16600 decls for now-static functions.
16601 * buffer.h (Fdelete_overlay): Remove decl.
16602 * callproc.c (Fgetenv_internal): Mark as internal.

16611 * image.c (Finit_image_library): New forward static decl.
16612 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
16613 * intervals.h (Fprevious_property_change):
16614 (Fremove_list_of_text_properties): Remove decls.
16615 * keyboard.c (Fthis_command_keys): Remove decl.
16616 (Fcommand_execute): New forward static decl.

16632 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
16634 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
16637 2011-04-13 Eli Zaretskii <eliz@gnu.org>
16639 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
16640 when at ZV. (Bug#8487)
16642 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
16644 * charset.c (Fclear_charset_maps): Use xfree instead of free.

16650 * xsettings.c (read_and_apply_settings): Likewise.
16652 * alloc.c (overrun_check_malloc, overrun_check_realloc)
16653 (overrun_check_free): Protoize.
16655 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
16657 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
16658 since callers should never pass a negative size.
16659 Change the signature to match that of plain 'read' and 'write'; see
16660 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
16661 * lisp.h: Update prototypes of emacs_write and emacs_read.
16663 2011-04-11 Eli Zaretskii <eliz@gnu.org>
16665 * xdisp.c (redisplay_window): Don't try to determine the character
16666 position of the scroll margin if the window start point w->startp
16667 is outside the buffer's accessible region. (Bug#8468)
16669 2011-04-10 Eli Zaretskii <eliz@gnu.org>
16671 Fix write-region and its subroutines for buffers > 2GB.
16672 * fileio.c (a_write, e_write): Modify declaration of arguments and
16673 local variables to support buffers larger than 2GB.
16674 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
16676 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
16677 argument, local variables, and return value.
16679 * lisp.h: Update prototypes of emacs_write and emacs_read.
16681 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
16683 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
16685 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
16687 Fix more problems found by GCC 4.6.0's static checks.
16689 * xdisp.c (vmessage): Use a better test for character truncation.
16691 * charset.c (load_charset_map): <, not <=, for optimization,
16692 and to avoid potential problems with integer overflow.
16693 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
16694 * casetab.c (set_identity, shuffle): Likewise.
16695 * editfns.c (Fformat): Likewise.
16696 * syntax.c (skip_chars): Likewise.
16698 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
16699 This also lets GCC 4.6.0 generate slightly better loop code.
16701 * callint.c (Fcall_interactively): <, not <=, for optimization.
16702 (Fcall_interactively): Count the number of arguments produced,
16703 not the number of arguments given. This is simpler and lets GCC
16704 4.6.0 generate slightly better code.
16706 * ftfont.c: Distingish more carefully between FcChar8 and char.
16707 The previous code passed unsigned char * to a functions like
16708 strlen and xstrcasecmp that expect char *, which does not
16709 conform to the C standard.
16710 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
16711 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
16712 char * when the C standard requires it.
16714 * keyboard.c (read_char): Remove unused var.
16716 * eval.c: Port to Windows vsnprintf (Bug#8435).
16717 Include <limits.h>.
16718 (SIZE_MAX): Define if the headers do not.
16719 (verror): Do not give up if vsnprintf returns a negative count.
16720 Instead, grow the buffer. This ports to Windows vsnprintf, which
16721 does not conform to C99. Problem reported by Eli Zaretskii.
16722 Also, simplify the allocation scheme, by avoiding the need for
16723 calling realloc, and removing the ALLOCATED variable.
16725 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
16727 Remove invocations of doprnt, as Emacs now uses vsnprintf.
16728 But keep the doprint source code for now, as we might revamp it
16729 and use it again (Bug#8435).
16730 * lisp.h (doprnt): Remove.
16731 * Makefile.in (base_obj): Remove doprnt.o.
16732 * deps.mk (doprnt.o): Remove.
16734 error: Print 32- and 64-bit integers portably (Bug#8435).
16735 Without this change, on typical 64-bit hosts error ("...%d...", N)
16736 was used to print both 32- and 64-bit integers N, which relied on
16737 undefined behavior.
16738 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
16739 * lisp.h (error, verror): Mark as printf-like functions.
16740 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
16741 Report overflow in size calculations when allocating printf buffer.
16742 Do not truncate output string at its first null byte.
16743 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
16744 Truncate the output at a character boundary, since vsnprintf does not
16746 * charset.c (check_iso_charset_parameter): Convert internal
16747 character to string before calling 'error', since %c now has the
16749 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
16750 overflow when computing char to be passed to 'error'. Do not
16751 pass Lisp_Object to 'error'; pass the integer instead.
16752 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
16753 formatted with plain %d.
16755 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
16757 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
16759 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
16761 * xterm.c (x_catch_errors): Remove duplicate declaration.
16763 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
16765 * xdisp.c, lisp.h (message_nolog): Remove; unused.
16767 2011-04-10 Jim Meyering <meyering@redhat.com>
16769 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
16770 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
16771 return ssize_t not "int", and use size_t as the buffer length.
16772 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
16773 * gnutls.h: Update declarations.
16774 * process.c (read_process_output): Use ssize_t, to match.
16775 (send_process): Likewise.
16777 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16779 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
16781 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16783 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
16784 Use unsigned char, to match FcChar8 type definition.
16786 * xterm.c (handle_one_xevent):
16787 * xmenu.c (create_and_show_popup_menu):
16788 * xselect.c (x_decline_selection_request)
16789 (x_reply_selection_request): Avoid type-punned deref of X events.
16791 2011-04-09 Eli Zaretskii <eliz@gnu.org>
16793 Fix some uses of `int' instead of EMACS_INT.
16794 * search.c (string_match_1, fast_string_match)
16795 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
16796 (scan_buffer, find_next_newline_no_quit)
16797 (find_before_next_newline, search_command, Freplace_match)
16798 (Fmatch_data): Make some `int' variables be EMACS_INT.
16800 * xdisp.c (display_count_lines): 3rd argument and return value now
16801 EMACS_INT. All callers changed.
16802 (pint2hrstr): Last argument is now EMACS_INT.
16804 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
16805 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
16806 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

16809 (decode_coding_ccl, decode_coding_charset)
16810 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
16811 (decode_coding_iso_2022, decode_coding_emacs_mule)
16812 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
16813 <char_offset, last_offset>: Declare EMACS_INT.

16815 (encode_coding_emacs_mule, encode_invocation_designation)
16816 (encode_designation_at_bol, encode_coding_iso_2022)
16817 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
16818 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
16820 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
16821 (encode_invocation_designation): Last argument P_NCHARS is now
16823 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
16824 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
16826 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
16829 * ccl.c (Fccl_execute_on_string): Declare some variables
16832 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
16834 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
16836 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
16838 * process.c (Fformat_network_address): Doc fix.
16840 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
16842 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
16844 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
16846 * keyboard.c (read_char): Call Lisp function help-form-show,
16847 instead of using internal_with_output_to_temp_buffer.
16848 (Qhelp_form_show): New var.
16849 (syms_of_keyboard): Use DEFSYM macro.
16851 * print.c (internal_with_output_to_temp_buffer): Function deleted.
16853 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
16855 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
16857 * process.c (Flist_processes): Remove to Lisp.
16858 (list_processes_1): Delete.
16860 2011-04-06 Eli Zaretskii <eliz@gnu.org>
16862 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
16864 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
16866 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
16868 Fix more problems found by GCC 4.6.0's static checks.
16870 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
16872 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
16874 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
16876 * xdisp.c (vmessage): Mark as a printf-like function.
16878 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
16880 * sound.c (sound_warning): Don't crash if arg contains a printf format.
16882 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
16883 printf-like functions.
16884 (tiff_load): Add casts to remove these marks before passing them
16885 to system-supplied API.
16887 * eval.c (Fsignal): Remove excess argument to 'fatal'.
16889 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
16890 This avoids several warnings with gcc -Wstrict-overflow.
16891 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
16892 directly, rather than having caller test rule sign. This avoids
16893 some unnecessary tests.
16894 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
16895 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
16896 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
16898 * xfont.c (xfont_text_extents): Remove var that was set but not used.
16899 (xfont_open): Avoid unnecessary tests.
16901 * composite.c (composition_gstring_put_cache): Use unsigned integer.
16903 * composite.h, composite.c (composition_gstring_put_cache):
16904 Use EMACS_INT, not int, for length.
16906 * composite.h (COMPOSITION_DECODE_REFS): New macro,
16907 breaking out part of COMPOSITION_DECODE_RULE.
16908 (COMPOSITION_DECODE_RULE): Use it.
16909 * composite.c (get_composition_id): Remove unused local vars,
16910 by using the new macro.
16912 * textprop.c (set_text_properties_1): Change while to do-while,
16913 since the condition is always true at first.
16915 * intervals.c (graft_intervals_into_buffer): Mark var as used.
16916 (interval_deletion_adjustment): Return unsigned value.
16919 * process.c (list_processes_1, create_pty, read_process_output):

16921 (create_pty): Remove unnecessary "volatile"s.
16922 (Fnetwork_interface_info): Avoid possibility of int overflow.

16935 * print.c (print_error_message): Avoid int overflow.
16937 * font.c (font_list_entities): Redo for clarity,
16938 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.

16953 (wordify): Omit three unnecessary tests.
16955 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

16960 * dired.c (file_name_completion): Remove var that is set but not used.
16962 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
16964 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
16965 (Finsert_file_contents): Remove unnecessary code checking fd.
16967 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
16968 Check for integer overflow on size calculations.
16970 * buffer.c (Fprevious_overlay_change): Remove var that is set
16973 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
16974 Remove vars that are set but not used.
16975 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
16976 (timer_check_2): Mark vars as initialized.
16978 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
16980 * image.c (lookup_image): Remove var that is set but not used.
16981 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
16983 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
16984 that are set but not used.
16986 * xfns.c (make_invisible_cursor): Don't return garbage
16987 if XCreateBitmapFromData fails (Bug#8410).
16989 * xselect.c (x_get_local_selection, x_handle_property_notify):
16990 Remove vars that are set but not used.
16992 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
16993 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
16995 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
16996 Remove var that is set but not used.
16997 (scroll_bar_windows_size): Now size_t, not int.
16998 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
16999 Check for overflow.
17001 * xfaces.c (realize_named_face): Remove vars that are set but not used.
17002 (map_tty_color) [!defined MSDOS]: Likewise.
17004 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
17006 * coding.c: Remove vars that are set but not used.
17007 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
17008 All callers changed.
17009 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
17010 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
17011 (decode_coding_charset): Remove vars that are set but not used.
17013 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
17014 that is set but not used.
17016 * print.c (print_object): Remove var that is set but not used.
17018 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
17019 The gnulib version avoids calling malloc in the usual case,
17020 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
17021 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
17022 * filelock.c (current_lock_owner): Likewise.
17023 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
17024 * sysdep.c: Include allocator.h, careadlinkat.h.
17025 (emacs_no_realloc_allocator): New static constant.
17026 (emacs_readlink): New function.
17027 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
17028 ../lib/careadlinkat.h.
17030 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
17032 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
17033 first non-nil return value).

17042 * xdisp.c (display_count_lines): Remove parameter `start',
17043 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
17044 (get_char_face_and_encoding): Remove parameter `multibyte_p',

17047 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
17048 and thereabouts. All callers changed.
17049 (get_per_char_metric): Remove parameter `f', unused since
17050 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
17052 2011-04-02 Jim Meyering <meyering@redhat.com>
17054 do not dereference NULL upon failed strdup
17055 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
17056 (ns_get_family): Likewise.
17058 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
17060 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
17062 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
17064 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
17067 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
17069 Add lexical binding.
17071 * window.c (Ftemp_output_buffer_show): New fun.
17072 (Fsave_window_excursion):
17073 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
17075 * lread.c (lisp_file_lexically_bound_p): New function.
17076 (Fload): Bind Qlexical_binding.
17077 (readevalloop): Remove `evalfun' arg.
17078 Bind Qinternal_interpreter_environment.
17079 (Feval_buffer): Bind Qlexical_binding.
17080 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
17082 (syms_of_lread): Declare `lexical-binding'.
17084 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
17086 * keyboard.c (eval_dyn): New fun.
17087 (menu_item_eval_property): Use it.
17089 * image.c (parse_image_spec): Use Ffunctionp.
17091 * fns.c (concat, mapcar1): Accept byte-code-functions.
17093 * eval.c (Fsetq): Handle lexical vars.
17094 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
17095 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
17096 (FletX, Flet): Obey lexical binding.
17097 (Fcommandp): Handle closures.
17098 (Feval): New `lexical' arg.
17099 (eval_sub): New function extracted from Feval. Use it almost
17100 everywhere where Feval was used. Look up vars in lexical env.
17102 (Ffunctionp): Move from subr.el.
17103 (Ffuncall): Handle closures.
17104 (apply_lambda): Remove `eval_flags'.
17105 (funcall_lambda): Handle closures and new byte-code-functions.
17106 (Fspecial_variable_p): New function.
17107 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
17108 but without exporting it to Lisp.
17110 * doc.c (Fdocumentation, store_function_docstring):
17111 * data.c (Finteractive_form): Handle closures.
17113 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
17116 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
17118 (exec_byte_code): New function extracted from Fbyte_code to handle new
17119 calling convention for byte-code-functions. Add new byte-codes.
17121 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
17123 * alloc.c (Fmake_symbol): Init new `declared_special' field.
17125 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
17127 * xdisp.c (redisplay_internal): Fix prototype.
17129 2011-03-31 Eli Zaretskii <eliz@gnu.org>
17131 * xdisp.c (SCROLL_LIMIT): New macro.
17132 (try_scrolling): Use it when setting scroll_limit.
17133 Limit scrolling to 100 screen lines.
17134 (redisplay_window): Even when falling back on "recentering",
17135 position point in the window according to scroll-conservatively,
17136 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
17138 (try_scrolling): When point is above the window, allow searching
17139 as far as scroll_max, or one screenful, to compute vertical
17140 distance from PT to the scroll margin position. This prevents
17141 try_scrolling from unnecessarily failing when
17142 scroll-conservatively is set to a value slightly larger than the
17143 window height. Clean up the case of PT below the margin at bottom
17144 of window: scroll_max can no longer be INT_MAX. When aggressive
17145 scrolling is in use, don't let point enter the opposite scroll
17146 margin as result of the scroll.
17147 (syms_of_xdisp) <scroll-conservatively>: Document the
17148 threshold of 100 lines for never-recentering scrolling.
17150 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
17152 * dispextern.h (move_it_by_lines):
17153 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

17155 (message_log_check_duplicate): Remove parameters `prev_bol' and
17156 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
17157 (redisplay_internal): Remove parameter `preserve_echo_area',
17158 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
17160 * indent.c (Fvertical_motion):
17161 * window.c (window_scroll_pixel_based, Frecenter):
17162 Don't pass `need_y_p' to `move_it_by_lines'.
17164 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
17166 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
17167 steal a few bits to be more compact.
17168 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
17169 Remove unneeded casts.
17171 * bytecode.c (Fbyte_code): CAR and CDR can GC.
17173 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
17175 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
17176 binding" message (bug#7967).
17178 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
17180 Fix more problems found by GCC 4.6.0's static checks.
17182 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
17183 Remove unused local var.
17185 * editfns.c (Fmessage_box): Remove unused local var.
17187 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
17188 (note_mode_line_or_margin_highlight, note_mouse_highlight):
17189 Omit unused local vars.
17190 * window.c (shrink_windows): Omit unused local var.
17191 * menu.c (digest_single_submenu): Omit unused local var.
17192 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
17193 Omit unused local var.
17195 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
17196 Don't assume string length fits in int.
17197 (keyremap_step, read_key_sequence): Use size_t for sizes.
17198 (read_key_sequence): Don't check last_real_key_start redundantly.
17200 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
17201 instead of alloca (Bug#8344).
17203 * eval.c (Fbacktrace): Don't assume nargs fits in int.
17204 (Fbacktrace_frame): Don't assume nframes fits in int.
17206 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

17211 * term.c (produce_glyphless_glyph): Remove unnecessary test.
17213 * cm.c (calccost): Turn while-do into do-while, for clarity.
17215 * keyboard.c (syms_of_keyboard): Use the same style as later
17216 in this function when indexing through an array. This also
17217 works around GCC bug 48267.
17219 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
17221 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
17223 * chartab.c (sub_char_table_ref_and_range): Redo for slight
17224 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
17226 * keyboard.c, keyboard.h (num_input_events): Now size_t.
17227 This avoids undefined behavior on integer overflow, and is a bit
17228 more convenient anyway since it is compared to a size_t variable.
17230 Variadic C functions now count arguments with size_t, not int.
17231 This avoids an unnecessary limitation on 64-bit machines, which
17232 caused (substring ...) to crash on large vectors (Bug#8344).

17242 * fns.c (concat): Likewise.
17243 * frame.c (x_set_frame_parameters): Likewise.
17244 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
17245 0 if not found, not -1. All callers changed.
17247 * alloc.c (garbage_collect): Don't assume stack size fits in int.
17248 (stack_copy_size): Now size_t, not int.
17249 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
17251 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
17253 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
17254 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
17255 All callers changed.
17257 * lisp.h (multibyte_char_to_unibyte):
17258 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
17259 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

17270 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
17271 don't set the hook to nil, but remove the offending function instead.
17272 (Qcommand_hook_internal): Remove, unused.
17273 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
17274 Vcommand_hook_internal.
17276 * eval.c (enum run_hooks_condition): Remove.
17277 (funcall_nil, funcall_not): New functions.
17278 (run_hook_with_args): Call each function through a `funcall' argument.
17279 Remove `cond' argument, now redundant.

17292 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
17293 All callers changed.
17295 * w32.c (_wsa_errlist): Use braces for struct initializers.
17297 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
17298 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
17299 All callers changed.

17444 * term.c (Fsuspend_tty, Fresume_tty):
17445 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
17446 * window.c (temp_output_buffer_show):

17454 * buffer.c (Fkill_all_local_variables):
17455 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
17457 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
17458 unconditionally since it does the check itself.
17460 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
17462 Fix more problems found by GCC 4.5.2's static checks.
17464 * coding.c (encode_coding_raw_text): Avoid unnecessary test
17465 the first time through the loop, since we know p0 < p1 then.
17466 This also avoids a gcc -Wstrict-overflow warning.
17468 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
17469 leading to a memory leak, possible in functions like
17470 load_charset_map_from_file that can allocate an unbounded number
17471 of objects (Bug#8318).
17473 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
17474 that could (at least in theory) be that large.
17476 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
17477 This is less likely to overflow, and avoids undefined behavior if
17478 overflow does occur. All callers changed. Use strtoul to scan
17479 for the unsigned long integer.
17480 (pint2hrstr): Simplify and tune code slightly.
17481 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

17491 * fileio.c (Fcopy_file): Report error if fchown or fchmod
17494 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
17496 * process.c (Fmake_network_process): Use socklen_t, not int,
17497 where POSIX says socklen_t is required in portable programs.
17498 This fixes a porting bug on hosts like 64-bit HP-UX, where
17499 socklen_t is wider than int (Bug#8277).
17500 (Fmake_network_process, server_accept_connection):
17501 (wait_reading_process_output, read_process_output):
17504 * process.c: Rename or move locals to avoid shadowing.

17514 Make tparam.h and terminfo.c consistent.
17515 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
17516 Include tparam.h instead, since it declares them.
17517 * cm.h (PC): Remove extern decl; tparam.h now does this.
17518 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
17519 * terminfo.c: Include tparam.h, to check interfaces.
17520 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
17521 (tparam): Adjust signature to match interface in tparam.h;
17522 this removes some undefined behavior. Check that outstring and len
17523 are zero, which they always are with Emacs.
17524 * tparam.h (PC, BC, UP): New extern decls.
17526 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
17527 (xftfont_open): Rename locals to avoid shadowing.

17544 (find_automatic_composition, composition_adjust_point): Likewise.
17545 (composition_update_it): Mark var as initialized.
17546 (find_automatic_composition): Mark vars as initialized,
17547 with a FIXME (Bug#8290).

17551 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
17552 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
17553 (BUF_DEC_POS): Be more systematic about renaming local temporaries
17554 to avoid shadowing.
17556 * textprop.c (property_change_between_p): Remove; unused.
17558 * intervals.c (interval_start_pos): Now static.
17560 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

17566 Fix pointer signedness.
17567 (alsa_choose_format): Remove unused local var.
17568 (wav_play): Initialize a variable to 0, to prevent undefined
17569 behavior (Bug#8278).
17571 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
17573 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
17575 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
17576 clobbering (Bug#8298).
17577 * sysdep.c (sys_subshell): Likewise.
17578 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
17580 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
17581 This should get cleaned up, so that child_setup has the
17582 same signature on all platforms.
17584 * callproc.c (call_process_cleanup): Now static.
17585 (relocate_fd): Rename locals to avoid shadowing.
17587 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
17589 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
17590 not to be necessary, and produces flickering.
17592 2011-03-20 Glenn Morris <rgm@gnu.org>
17594 * config.in: Remove file.
17596 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

17626 (sigchld_handler): Now static.
17628 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
17629 That way, the code declares only the vars that it needs.

17639 (CONSTANTLIM): Remove; unused.
17640 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
17641 Define only if needed.
17643 * unexelf.c (unexec): Name an expression,
17644 to avoid gcc -Wbad-function-cast warning.
17645 Use a different way to cause a compilation error if anyone uses
17646 n rather than nn, a way that does not involve shadowing.
17647 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
17649 * deps.mk (unexalpha.o): Remove; unused.
17651 New file unexec.h, the (simple) interface for unexec (Bug#8267).

17726 ENABLE_CHECKING is not defined.
17728 * data.c (Findirect_variable): Name an expression, to avoid
17729 gcc -Wbad-function-cast warning.

17772 (RETALLOC_IF): Define only if needed.
17773 (WORDCHAR_P): Likewise. This one is never needed, but is used
17774 only in a comment talking about a compiler bug, so put inside
17775 the #if 0 of that comment.

17805 gcpro1, gcpro2, etc.
17806 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
17808 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
17809 argument, for consistency with GCPRO2_VAR, etc: it is now the

17813 Rename locals to avoid shadowing.
17815 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
17816 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
17817 dired.c's scmp function, had undefined behavior.
17818 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
17819 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
17820 * buffer.h: ... to here, because these macros use current_buffer,
17821 and the new implementation with inline functions needs to have
17822 current_buffer in scope now, rather than later when the macros
17824 (downcase, upcase1): New static inline functions.
17825 (DOWNCASE, UPCASE1): Reimplement using these functions.
17826 This avoids undefined behavior in expressions like

17867 * buffer.c (fix_overlays_before): Mark locals as initialized.
17868 (fix_start_end_in_overlays): Likewise. This function should be
17869 simplified by using pointers-to-pointers, but that's a different

17873 (report_overlay_modification): Rename locals to avoid shadowing.

17878 to suppress a gcc -Wclobbered warning that does not seem to be right.
17879 (MAXPATHLEN): Define only if needed.
17881 * process.c (serial_open, serial_configure): Move decls from here ...
17882 * systty.h: ... to here, so that they can be checked.
17884 * fns.c (get_random, seed_random): Move extern decls from here ...

17887 * sysdep.c (reset_io): Now static.
17888 (wait_for_termination_signal): Remove; unused.
17890 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

17896 (describe_map_tree):
17897 Rename locals to avoid shadowing.

18224 * coding.c (coding_set_source, coding_set_destination):

18226 for clarity, and to avoid gcc -Wempty-body warning.
18227 (Fdefine_coding_system_internal): Don't redeclare 'i' inside
18228 a block, when the outer 'i' will do.
18229 (decode_coding_utf_8, decode_coding_utf_16, detect_coding_emacs_mule):

18240 (decode_coding_emacs_mule): Mark variables that gcc
18241 -Wuninitialized does not deduce are never used uninitialized.
18242 (detect_coding_iso_2022): Initialize a local variable that might
18243 be used uninitialized. Leave a FIXME because it's not clear that
18244 this initialization is needed. (Bug#8211)
18245 (ISO_CODE_LF, ISO_CODE_CR, CODING_ISO_FLAG_EUC_TW_SHIFT):
18246 (ONE_MORE_BYTE_NO_CHECK, UTF_BOM, UTF_16_INVALID_P):

18277 Move these decls to tparam.h, and make them agree with what
18278 is actually in tparam.c. The previous trick of using incompatible
18279 decls in different modules does not conform to the C standard.
