3 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
5 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
6 as the previous version used 'void *'.
8 * ralloc.c (ROUNDUP): Fix last change.
9 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
12 * w32proc.c <disable_itimers>: New static flag.
13 (init_timers): Initialize it to zero, after creating the critical
14 sections used by the timer threads.
15 (term_timers): Set to 1 before deleting the critical sections.
16 (getitimer, setitimer): If disable_itimers is non-zero, return an
17 error indication without doing anything. Reported by Fabrice
18 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
19 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
21 [!HAVE_SETITIMER]: Behave as the previous version that didn't
24 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
25 term_ntproc after all the other bookkeeping, to get timers working
28 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
30 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
31 Suggested by Juri Linkov in
32 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
34 Prefer plain 'static' to 'static inline' (Bug#12541).
35 With static functions, modern compilers inline pretty well by
36 themselves; advice from programmers often hurts as much as it helps.
37 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
38 this change shrinks the text size of the Emacs executable by 1.1%
39 without affecting CPU significantly in my benchmark.

122 Revert the FOLLOW-SYMLINKS change for file-attributes.
123 Doing it right would require several changes to Tramp, and there's
124 not enough time to get that tested before the freeze today.
125 * dired.c (directory_files_internal, Ffile_attributes):
128 * frame.c (x_report_frame_params): Port better to wider ints.
129 Do not assume that EMACS_UINT is the same width as uprintmax_t,
130 or that pointers can be printed in 15 decimal digits.
131 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

341 Prefer timer_settime if available, and prefer
342 thread cputime clocks, then process cputime clocks, then
343 monotonic clocks, to the old realtime clock. Use make_timeval
344 to round more-correctly when falling back to setitimer.
345 (Fprofiler_cpu_start): Use it.
346 (Fprofiler_cpu_stop): Prefer timer_settime if available.
347 Don't assume that passing NULL as the 2nd argument of setitimer

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

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

469 * image.c (reset_image_types): New function.
471 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

480 2012-09-25 Eli Zaretskii <eliz@gnu.org>
482 * w32proc.c (sys_signal): Handle all signals defined by the
483 MS-Windows runtime, not just SIGCHLD. Actually install the signal
484 handlers for signals supported by Windows. Don't override
485 term_ntproc as the handler for SIGABRT.
486 (sigaction): Rewrite to call sys_signal instead of duplicating its
488 (sys_kill): Improve commentary.
490 * w32.c (term_ntproc): Accept (and ignore) one argument, for
491 consistency with a signature of a signal handler. All callers
493 (init_ntproc): Accept an argument DUMPING. If dumping, don't
494 install term_ntproc as a signal handler for SIGABRT, as that
495 should be done by the dumped Emacs.
497 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
499 * w32select.c (term_w32select): Protect against repeated
500 invocation by setting clipboard_owner to NULL after calling
503 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
504 and term_ntproc to their modified signatures.
506 * character.c (char_string, string_char): Remove calls to
507 MAYBE_UNIFY_CHAR. See the discussion starting at
508 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
511 2012-09-25 Chong Yidong <cyd@gnu.org>
513 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
515 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
517 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
518 when encountering an unknown bytecode.
520 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
522 image.c, indent.c: Use bool for booleans.
523 * dispextern.h (struct image_type): Members valid_p, load, init
524 now return bool, not int. All uses changed.
525 * image.c: Omit unnecessary static decls.
526 (x_create_bitmap_mask, x_build_heuristic_mask):
527 Return void, not int, since callers don't care about the return value.

560 * chartab.c (Fset_char_table_default): Obsolete function removed.
562 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
564 Move pid_t related decls out of lisp.h.
565 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
566 (interruptible_wait_for_termination):
567 Move these decls from lisp.h to syswait.h, since they use pid_t.
568 Needed on FreeBSD; see Herbert J. Skuhra in
569 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
570 * callproc.c: Include syswait.h.

590 Use bool for boolean.
591 * gtkutil.c (xg_update_frame_menubar):
592 * xmenu.c (update_frame_menubar):
593 Return void, not int, since caller ignores return value.

597 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
599 * makefile.w32-in (BLOCKINPUT_H): Remove.

616 2012-09-23 Eli Zaretskii <eliz@gnu.org>
618 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
619 fatal_error_backtrace.
621 * w32proc.c (sys_kill): Undo last change: don't do anything when
622 invoked to deliver SIGABRT to our own process. This is now
623 handled by emacs_raise.
625 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
627 * w32term.c (w32_read_socket): Remove leftover reference to
628 interrupt_input_pending.
630 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
632 Do not use SA_NODEFER.
633 Problem reported by Dani Moncayo in
634 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
636 * sysdep.c (emacs_abort): Do not reset signal handler.
637 * emacs.c (terminate_due_to_signal): Reset signal handler here.
638 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
639 wanted even on POSIXish hosts, and it doesn't work on Windows.
641 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
643 * xterm.c (x_term_init): Call fixup_locale before and after calling
644 gtk_init (Bug#12392).
646 2012-09-23 Chong Yidong <cyd@gnu.org>
648 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
649 Vdynamic_library_alist.
651 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
652 (Fgnutls_available_p): Caller changed.
654 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
655 (Flibxml_parse_xml_region): Likewise.
657 * dispextern.h (struct image_type): Remove arg from init function.
659 * image.c (Finit_image_library, lookup_image_type)
660 (define_image_type): Remove now-unneeded second arg.
661 (init_xpm_functions, init_png_functions, init_jpeg_functions)
662 (init_tiff_functions, init_gif_functions, init_svg_functions):
663 Arglist and w32_delayed_load calling convention changed.
664 (gs_type): Remove init_gs_functions; there is no such function.
665 (valid_image_p, make_image): Fix caller to lookup_image_type.
667 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
669 Simplify and avoid signal-handling races (Bug#12471).
671 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
672 Avoid recursive loop if there's a fatal error in the function itself.
673 * atimer.c (pending_atimers):
674 * blockinput.h: Don't include "atimer.h"; no longer needed.
675 (interrupt_input_pending): Remove. All uses removed.
676 pending_signals now counts both atimers and ordinary interrupts.
677 This is less racy than having three separate pending-signal flags.
678 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
680 Rename from their upper-case counterparts BLOCK_INPUT,
681 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
682 INPUT_BLOCKED_P, and turn into functions. All uses changed.
683 This makes it easier to access volatile variables more accurately.
684 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
685 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
686 that's more reliable if the code is buggy and sets
687 interrupt_input_blocked to a negative value. All uses changed.
688 * atimer.c (deliver_alarm_signal):
689 Remove. No need to deliver this to the parent; any thread can
690 handle this signal now. All uses replaced by underlying handler.
691 * atimer.c (turn_on_atimers):
692 * dispnew.c (handle_window_change_signal):
693 * emacs.c (handle_danger_signal):
694 * keyboard.c (kbd_buffer_get_event):
695 Don't reestablish signal handler; not needed with sigaction.
696 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
698 Rework to avoid unnecessary accesses to volatile variables.
699 (UNBLOCK_INPUT_TO): Now a function.
700 (totally_unblock_input, unblock_input): New decls.
701 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
702 (init_data): Remove. Necessary stuff now done in init_signal.
703 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
704 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
705 (fatal_error_code): Remove; no longer needed.
706 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
707 it doesn't always backtrace. All uses changed. No need to reset
708 signal to default, since sigaction and/or die does that for us now.
709 Use emacs_raise (FOO), not kill (getpid (), FOO).
710 (main): Check more-accurately whether we're dumping.
711 Move fatal-error setup to sysdep.c
712 * floatfns.c: Do not include "syssignal.h"; no longer needed.
713 * gtkutil.c (xg_get_file_name, xg_get_font):
714 Remove no-longer-needed signal-mask manipulation.
715 * keyboard.c, process.c (POLL_FOR_INPUT):
716 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
717 * keyboard.c (read_avail_input): Remove.
718 All uses replaced by gobble_input.
719 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
720 (kbd_buffer_store_event_hold, gobble_input):
721 (record_asynch_buffer_change) [USABLE_SIGIO]:
722 (store_user_signal_events):
723 No need to mess with signal mask.
724 (gobble_input): If blocking input and there are terminals, simply
725 set pending_signals to 1 and return. All hooks changed to not
726 worry about whether input is blocked.
727 (process_pending_signals): Clear pending_signals before processing
728 them, in case a signal comes in while we're processing.
729 By convention callers now test pending_signals before calling us.
730 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
731 New functions, to support changes to blockinput.h.
732 (handle_input_available_signal): Now extern.
733 (reinvoke_input_signal): Remove. All uses replaced by
735 (quit_count): Now volatile, since a signal handler uses it.
736 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
737 All callers changed. Block SIGINT only if not already blocked.
738 Clear sigmask reliably, even if Fsignal returns, which it can.
739 Omit unnecessary accesses to volatile var.
740 (quit_throw_to_read_char): No need to restore sigmask.
741 * keyboard.c (gobble_input, handle_user_signal):
742 * process.c (wait_reading_process_output):
743 Call signal-handling code rather than killing ourselves.
744 * lisp.h: Include <float.h>, for...
745 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
746 (pending_signals): Now volatile.
747 (syms_of_data): Now const if IEEE floating point.
748 (handle_input_available_signal) [USABLE_SIGIO]:
749 (terminate_due_to_signal, record_child_status_change): New decls.
750 * process.c (create_process): Avoid disaster if memory is exhausted
751 while we're processing a vfork, by tightening the critical section
753 (send_process_frame, process_sent_to, handle_pipe_signal)
754 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
756 (send_process): No need for setjmp/longjmp any more, since the
757 SIGPIPE stuff is now gone. Instead, report an error if errno
759 (record_child_status_change): Now extern. PID and W are now args.
760 Return void, not bool. All callers changed.
761 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
762 Remove. All uses removed. This bug should be fixed now in a
764 (wait_for_termination_1): Use waitpid rather than sigsuspend,
765 and record the child status change directly. This avoids the
766 need to futz with the signal mask.
767 (process_fatal_action): Move here from emacs.c.
768 (emacs_sigaction_flags): New function, containing
769 much of what used to be in emacs_sigaction_init.
770 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
771 caught by emacs, to make races less likely.
772 (deliver_process_signal): Rename from handle_on_main_thread.
774 (BACKTRACE_LIMIT_MAX): Now at top level.
775 (thread_backtrace_buffer, threadback_backtrace_pointers):
777 (deliver_thread_signal, deliver_fatal_thread_signal):
778 New functions, for more-accurate delivery of thread-specific signals.
779 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
780 (deliver_arith_signal): Handle in this thread, not
781 in the main thread, since it's triggered by this thread.
782 (maybe_fatal_sig): New function.
783 (init_signals): New arg DUMPING so that we can be more accurate
784 about whether we're dumping. Caller changed.
785 Treat thread-specific signals differently from process-general signals.
786 Block all signals while handling fatal error; that's safer.
787 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
789 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
790 Ignore SIGPIPE unless batch.
791 (emacs_backtrace): Output backtrace for the appropriate thread,
792 which is not necessarily the main thread.
793 * syssignal.h: Include <stdbool.h>.
794 (emacs_raise): New macro.
795 * xterm.c (x_connection_signal): Remove; no longer needed
796 now that we use sigaction.
797 (x_connection_closed): No need to mess with sigmask now.
798 (x_initialize): No need to reset SIGPIPE handler here, since
799 init_signals does this for us now.
801 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
803 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
804 background rect may be larger (Bug#12245).
806 2012-09-23 Chong Yidong <cyd@gnu.org>
808 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
810 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
812 * .gdbinit: Just stop at fatal_error_backtrace.
813 See Stefan Monnier's request in
814 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
815 Remove no-longer-used query of system type.
817 2012-09-22 Chong Yidong <cyd@gnu.org>
819 * search.c (Freplace_match): Doc fix (Bug#12325).
821 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
823 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
824 (Fline_end_position): Doc fix.

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

860 (Vwindow_combination_limit): New default value.
863 2012-09-22 Eli Zaretskii <eliz@gnu.org>
865 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
866 the new overlay string. (Bug#10159)
868 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
870 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
871 or that fprintf is async-signal-safe. POSIX doesn't require
874 2012-09-22 Chong Yidong <cyd@gnu.org>
876 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
879 2012-09-22 Kenichi Handa <handa@gnu.org>
881 * composite.c (composition_reseat_it): Handle the case that a
882 grapheme cluster is not covered by a single font (Bug#12352).
884 2012-09-21 Chong Yidong <cyd@gnu.org>
886 * image.c (define_image_type): Avoid adding duplicate types to
887 image_types (Bug#12463). Suggested by Jörg Walter.
889 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
891 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
892 (print_load_command_name): Add case LC_DATA_IN_CODE.
893 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
895 2012-09-21 Glenn Morris <rgm@gnu.org>
897 * eval.c (Frun_hook_with_args_until_success)
898 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
900 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
902 * fileio.c (Ffile_selinux_context): Only call freecon when
903 lgetfilecon succeeded.
904 (Fset_file_selinux_context): Likewise. (Bug#12444)
906 2012-09-21 Eli Zaretskii <eliz@gnu.org>
908 * xdisp.c (try_window_reusing_current_matrix): Under bidi
909 reordering, locate the cursor by calling set_cursor_from_row; if
910 that fails, clear the desired glyph matrix before returning a
911 failure indication to the caller. Fixes leaving garbled display
912 when fast scrolling with a down-key. (Bug#12403)
913 (compute_stop_pos_backwards): Fix a typo that caused crashes while
914 scrolling through multibyte text.
916 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
918 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
919 calling mark_vectorlike since that's the one that marks the window.
920 (mark_discard_killed_buffers): Mark the final cdr.
921 * window.h (struct window): Move prev/next_buffers to the
923 * window.c (make_window): Initialize prev/next_buffers manually.
925 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
927 Omit unused arg EXPECTED from socket hooks.
928 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
929 * nsterm.m (ns_term_init):
930 * termhooks.h (struct terminal.read_socket_hook):
931 * w32inevt.c (w32_console_read_socket):
932 * w32term.c (w32_read_socket):
933 * xterm.c (XTread_socket):
934 Omit unused arg EXPECTED. All callers changed.
935 (store_user_signal_events): Return void, not int, since callers no
936 longer care about the return value. All uses changed.
938 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
940 * w32gui.h (XParseGeometry): Do not declare.
942 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
944 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
945 Ignore 'expected'. See Eli Zaretskii in
946 <http://bugs.gnu.org/12471#8> (last line).
948 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
949 (XParseGeometry): Now static. Substitute extremal values for
950 values that are out of range.
952 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
954 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
956 * nsfns.m (XParseGeometry): Remove.
957 (Fx_create_frame): Call x_set_offset to correctly interpret
960 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
961 (Fx_parse_geometry): If there is a space in string, call
962 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
964 2012-09-17 Eli Zaretskii <eliz@gnu.org>
966 * search.c (scan_buffer): Use character positions in calls to
967 region_cache_forward and region_cache_backward, not byte
968 positions. (Bug#12196)
970 * w32term.c (w32_read_socket): Set pending_signals to 1, like
971 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
973 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
974 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
975 emacs_blocked_malloc, now deleted.
977 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
979 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
980 The workaround was for improving performance on Solaris 2.4, but
981 is getting in the way now. Emacs will still work if someone is
982 still running Solaris 2.4 in a museum somewhere; Sun dropped
983 support for Solaris 2.4 in 2003.
984 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
985 * process.c (create_process) [HAVE_WORKING_VFORK]:
986 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
987 since Emacs no longer uses vfork on that platform.
989 2012-09-17 Glenn Morris <rgm@gnu.org>
991 * emacs.c: Use COPYRIGHT.
993 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
995 Remove configure's --without-sync-input option (Bug#12450).
996 When auditing signal-handling in preparation for cleaning it up,
997 I found that SYNC_INPUT has race conditions and would be a real
998 pain to fix. Since it's an undocumented and deprecated
999 configure-time option, now seems like a good time to remove it.
1000 Also see <http://bugs.gnu.org/11080#16>.
1001 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
1002 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
1003 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
1004 (malloc_hysteresis):
1005 (check_depth) [XMALLOC_OVERRUN_CHECK]:
1006 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
1007 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
1008 (dont_register_blocks, bytes_used_when_reconsidered)
1009 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
1010 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
1011 [!SYSTEM_MALLOC && !SYNC_INPUT]:
1012 Remove. All uses removed.
1013 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
1014 implementation, one that depends on whether the new macro
1015 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
1017 * atimer.c (run_timers, handle_alarm_signal):
1018 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
1019 (handle_async_input, process_pending_signals)
1020 (handle_input_available_signal, init_keyboard):
1021 * nsterm.m (ns_read_socket):
1022 * process.c (wait_reading_process_output):
1023 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
1024 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
1026 * xterm.c (XTread_socket):
1028 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
1029 * eval.c (handling_signal): Remove. All uses removed.
1030 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
1031 All uses replaced with the SYNC_INPUT version.
1032 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
1034 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1037 * font.c (Ffont_shape_gstring): Remove unused local.
1039 2012-09-16 Glenn Morris <rgm@gnu.org>
1041 * Makefile.in (clean): No longer run nextstep's clean.
1043 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
1045 (ns-app): Move here from ns.mk, and simplify.
1046 (clean): Simplify nextstep entry.
1047 * ns.mk: Remove file.
1049 2012-09-17 Kenichi Handa <handa@gnu.org>
1051 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
1052 not covert the last few charactes.
1054 2012-09-16 Kenichi Handa <handa@gnu.org>
1056 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
1057 here, but just check the validity of glyphs in the glyph-string.
1059 2012-09-16 Martin Rudalics <rudalics@gmx.at>
1061 * window.c (Fwindow_parameter, Fset_window_parameter):
1062 Accept any window as argument (Bug#12452).
1064 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
1066 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
1067 to ns_term_init to avoid memory leak.
1069 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
1070 explicit retain/release.
1071 (ns_term_init): Only allow one display. Initialize outerpool and
1074 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1076 Port _setjmp fix to POSIXish hosts as well as Microsoft.
1077 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
1078 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
1079 the Microsoft problem in a different way, by altering ../nt/config.nt.
1081 2012-09-15 Eli Zaretskii <eliz@gnu.org>
1096 * w16select.c: Remove inclusion of setjmp.h, as it is now included
1097 by lisp.h. This completes removal of setjmp.h inclusion
1098 erroneously announced in the previous commit. (Bug#12446)
1100 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
1103 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
1104 not defined as a macro. The latter happens on MS-Windows.
1107 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1109 Port better to POSIX hosts lacking _setjmp (Bug#12446).
1110 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
1111 Some instances of '#include <setjmp.h>' removed, if the
1112 only reason for the instance was because "lisp.h" was included.
1113 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
1114 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
1115 and _longjmp with the new symbols. Emacs already uses _setjmp if
1116 available, so this change affects only POSIXish hosts that have
1117 sigsetjmp but not _setjmp, such as some versions of Solaris and
1118 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
1119 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
1120 (png_load_body) [HAVE_PNG]:
1121 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
1122 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
1123 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
1124 since PNG requires jmp_buf. This is the only exception to the
1125 general rule that we now use sys_setjmp and sys_longjmp.
1126 This exception is OK since this code does not change the signal
1127 mask or longjmp out of a signal handler.
1129 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
1131 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
1132 Include "syssignal.h", for 'main_thread'.
1134 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
1136 Avoid out-of-range marker position (Bug#12426).
1137 * insdel.c (replace_range, replace_range_2):
1138 Adjust markers before overlays, as suggested by comments.
1139 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
1140 Remove redundant check before calling offset_intervals.
1142 2012-09-14 Martin Rudalics <rudalics@gmx.at>
1144 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
1145 current buffer (Bug#12387).
1147 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
1149 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
1151 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
1153 Use a more backwards-compatible timer format (Bug#12430).
1154 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
1155 vector element, not from the 4th, since PSECS is now at the end.
1156 (Fcurrent_idle_time): Doc fix.
1158 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
1160 Function to mark objects and remove killed buffers at once.
1161 * alloc.c (discard_killed_buffers): Rename to ...
1162 (mark_discard_killed buffers) ... new name. Add marking
1163 of remaining objects. Fix comment. Adjust users.
1164 (mark_object): Do not touch frame buffer lists here.
1165 * frame.c (delete_frame): Reset frame buffer lists here.
1167 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
1169 Better workaround for GNOME bug when --enable-gcc-warnings.
1170 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
1171 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
1172 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
1174 Simplify SIGIO usage (Bug#12408).
1175 The code that dealt with SIGIO was crufty and confusing, e.g., it
1176 played tricks like "#undef SIGIO" but these tricks were not used
1177 consistently. Simplify mostly by not #undeffing standard symbols,
1178 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
1179 or not as we please) rather than "defined SIGIO" (standard symbol
1180 that we probably shouldn't #undef).
1181 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
1182 Modules that need it can include it.
1183 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
1184 * dispextern.h (ignore_sigio): New decl.
1185 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
1186 unconditionally, since it's now a no-op if !USABLE_SIGIO.
1187 * emacs.c (shut_down_emacs):
1188 * keyboard.c (kbd_buffer_store_event_hold):
1189 Use ignore_sigio rather than invoking 'signal' directly.
1190 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
1192 (FIONREAD, SIGIO): Do not #undef.
1193 (tty_read_avail_input): Use #error rather than a syntax error.
1194 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
1195 for I_PIPE, used by SETUP_SLAVE_PTY.
1196 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
1197 * sysdep.c (croak): Remove; no longer needed. This bit of
1198 temporary code, with Fred N. Fish's comment that it's temporary,
1199 has been in Emacs since at least 1992!
1200 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
1201 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
1202 * syssignal.h (croak): Remove decl.
1203 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
1204 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
1205 now that we're termios-only.
1206 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
1207 * term.c (dissociate_if_controlling_tty): Use #error rather than
1210 Work around GCC and GNOME bugs when --enable-gcc-warnings.
1211 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
1212 to work around GNOME bug 683906.
1213 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
1214 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
1215 This works around GCC bug 54561.
1217 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
1219 More fixes for 'volatile' and setjmp/longjmp.
1220 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
1221 * image.c (struct png_load_context) [HAVE_PNG]: New type.
1222 (png_load_body) [HAVE_PNG]:
1223 (jpeg_load_body) [HAVE_JPEG]:
1224 New function, with most of the old parent function's body.
1225 (png_load) [HAVE_PNG]:
1226 (jpeg_load) [HAVE_JPEG]:
1227 Invoke the new function, to avoid longjmp munging our locals.
1228 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
1229 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
1230 longjmp is passed 2, as the C standard doesn't guarantee this.
1231 Instead, store the failure code into mgr->failure_code.
1233 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
1235 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
1236 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
1237 (syms_of_keyboard): Remove support for unread-command-char.
1239 2012-09-12 Eli Zaretskii <eliz@gnu.org>
1241 * w32proc.c (sys_kill): If PID is our process ID and the signal is
1242 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
1243 violation. (Bug#12426)
1245 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
1247 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
1249 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
1251 * eval.c: Add `inhibit-debugger'.
1252 (Qinhibit_debugger): New symbol.
1253 (call_debugger): Bind it instead of Qdebug_on_error.
1254 (maybe_call_debugger): Test Vinhibit_debugger.
1255 (syms_of_eval): Define inhibit-debugger.
1256 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
1257 (syms_of_xdisp): Remove inhibit-debug-on-message.
1259 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
1261 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
1262 If a nonvolatile local variable is written before a _longjmp to
1263 the frame containing the variable, and is read after the _longjmp,
1264 the value read is indeterminate. Some local variables of type
1265 'struct handler' and 'struct catchtag' are used in this way, so
1266 mark each of their slots as volatile if the slot can be set before
1267 _longjmp and read afterwards.
1268 * lisp.h (struct handler): var and chosen_clause are now volatile.
1269 (struct catchtag): val, next, and pdlcount are now volatile.
1271 * bidi.c (bidi_push_it, bidi_pop_it):
1272 * fns.c (copy_hash_table):
1273 * image.c (define_image_type):
1274 * keyboard.c (kbd_buffer_store_event_hold):
1275 * process.c (Fprocess_send_eof):
1276 * xfaces.c (x_create_gc) [HAVE_NS]:
1277 * xgselect.c (xg_select):
1278 Prefer assignment to memcpy when either will do.
1280 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
1281 Use pointer-to-a-pointer to simplify and avoid a NILP check each
1282 time an item is removed. No need to mark this function 'inline';
1283 the compiler knows better than we do.
1285 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
1287 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
1288 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
1289 to change_frame_size (Bug#12388).
1290 (windowDidResize:): Pass YES to updateFrameSize.
1292 * nsterm.h: Add delay parameter to updateFrameSize.
1294 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
1296 Discard killed buffers from deleted window and frame objects.
1297 This reduces an amount of references to killed buffers and
1298 helps GC to reclaim them faster.
1299 * alloc.c (discard_killed_buffers): New function.
1300 (mark_object): Use it for deleted windows and frames.
1301 (mark_object): If symbol's value is set up for a killed buffer
1302 or deleted frame, restore it's global binding.
1303 * data.c (swap_in_global_binding): Add GC notice.
1304 (swap_in_symval_forwarding): Use convenient set_blv_where.
1305 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
1306 * window.h: ... to here.
1308 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
1310 Convenient macro to check whether the buffer is live.
1311 * buffer.h (BUFFER_LIVE_P): New macro.
1312 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
1313 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
1315 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1317 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
1318 composition cases (Bug#12364).
1320 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
1321 overhang of succeeding glyphs overlapping box cursor.
1323 * w32term.c (x_draw_glyph_string): Likewise.
1325 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
1327 Simplify, document, and port floating-point (Bug#12381).
1328 The porting part of this patch fixes bugs on non-IEEE platforms
1329 with frexp, ldexp, logb.
1330 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
1332 * floatfns.c: Simplify discussion of functions that Emacs doesn't
1333 support, by removing commented-out code and briefly listing the
1334 C89 functions excluded. The commented-out stuff was confusing
1335 maintenance, e.g., we thought we needed cbrt but it was commented out.
1336 (logb): Remove decl; no longer needed.
1337 (isfinite): New macro, if not already supplied.
1338 (isnan): Don't replace any existing macro.
1339 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
1340 are present on all C89 platforms.
1341 (Ffrexp): Do not special-case zero, as frexp does the right thing
1343 (Flogb): Do not use logb, as it doesn't have the desired meaning
1344 on hosts that use non-base-2 floating point. Instead, stick with
1345 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
1346 frexp, to avoid getting an unspecified result.
1348 * xdisp.c (Qinhibit_debug_on_message): Now static.
1350 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
1352 * nsterm.m (ns_update_begin): Set clip path to whole view by using
1353 NSBezierPath (Bug#12131).
1355 2012-09-10 Chong Yidong <cyd@gnu.org>
1357 * fns.c (Fdelq, Fdelete): Doc fix.
1359 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
1361 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
1362 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
1364 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
1366 * lisp.h (make_lisp_ptr): New macro to replace XSET.
1367 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
1370 2012-09-09 Eli Zaretskii <eliz@gnu.org>
1372 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
1373 left fringe if the window has a left margin. This avoids leaving
1374 traces of the cursor because its leftmost pixel is not drawn over.
1376 * dispnew.c (update_window_line): When the left margin area of a
1377 screen line is updated, set the redraw_fringe_bitmaps_p flag of
1378 that screen line. (Bug#12277)
1380 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
1382 Assume C89 or later for math functions (Bug#12381).
1383 This simplifies the code, and makes it a bit smaller and faster,
1384 and (most important) makes it easier to clean up signal handling
1385 since we can stop worring about floating-point exceptions in
1386 library code. That was a problem before C89, but the problem
1387 went away many years ago on all practical Emacs targets.
1388 * data.c, image.c, lread.c, print.c:
1389 Don't include <math.h>; no longer needed.
1390 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
1391 might be autoconfigured, as that never happens.
1393 * doprnt.c (DBL_MAX_10_EXP):
1394 * print.c (DBL_DIG):
1395 Remove. C89 or later always defines these.
1396 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
1397 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
1398 (arith_error, domain_error, domain_error2):
1399 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
1400 no longer needed -- we simply return what C returns. All uses removed.
1401 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
1403 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
1404 Remove. All uses expanded, as these macros are no longer used
1405 more than once and are now more trouble than they're worth.
1406 (Ftan): Use tan, not sin / cos.
1407 (Flogb): Assume C89 frexp.
1408 (fmod_float): Assume C89 fmod.
1409 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
1410 (init_floatfns): Remove. All uses removed.
1412 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1414 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
1415 compositeToPoint for OSX < 10.6 (Bug#12390).
1417 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
1419 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
1420 This produces more-accurate results.
1422 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1424 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
1425 changes (Bug#12088).
1427 2012-09-08 Chong Yidong <cyd@gnu.org>
1429 * syntax.c (Fstring_to_syntax): Doc fix.
1431 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1433 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
1434 in the internal border.
1435 (x_set_window_size): Remove static variables and their usage.
1436 (ns_redraw_scroll_bars): Fix NSTRACE arg.
1437 (ns_after_update_window_line, ns_draw_fringe_bitmap):
1438 Remove fringe/internal border adjustment (Bug#11052).
1439 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
1440 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
1441 (ns_fix_rect_ibw): Remove.
1442 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
1443 (ns_dumpglyphs_box_or_relief): Ditto.
1444 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
1446 (ns_dumpglyphs_image): Ditto.
1447 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
1449 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
1450 their usage. Add fringe_extended_p and its use as in other terms.
1451 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
1452 scroll bar was removed.
1453 (updateFrameSize): New function.
1454 (windowDidResize): Move code to updateFrameSize and call it.
1456 * nsterm.h (EmacsView): Add updateFrameSize.
1458 2012-09-07 Chong Yidong <cyd@gnu.org>
1460 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
1462 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
1464 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1466 More signal-handler cleanup (Bug#12327).
1467 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
1468 Problem introduced when merging patches. Noted by Eli Zaretskii in
1469 <http://bugs.gnu.org/12327#67>.
1470 * floatfns.c: Comment fix.
1471 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
1472 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
1473 and anyway the declaration is harmless even if SIGDANGER is not defined.
1474 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
1475 defined BROKEN_FIONREAD). systty.h formerly did this, but other
1476 source files not surprisingly expected syssignal.h to define, or
1477 not define, SIGIO, and it's cleaner to do it that way, for consistency.
1478 Include <sys/ioctl.h>, for FIONREAD.
1479 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
1480 This eliminates a problem whereby other files mysteriously had
1481 to include "syssignal.h" before including "systty.h" if they
1482 wanted to use "#ifdef SIGIO".
1484 2012-09-07 Eli Zaretskii <eliz@gnu.org>
1486 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
1488 * w32.c (sigemptyset): Empty the set.
1489 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
1491 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
1493 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
1495 * alloc.c (mark_buffer): Revert unsafe marking optimization.
1496 (mark_object): Likewise for frame objects.
1498 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1500 * syssignal.h (handle_on_main_thread): Always declare,
1501 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
1502 This ports to platforms without HAVE_PTHREAD.
1504 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1506 Signal-handler cleanup (Bug#12327).
1507 Emacs's signal handlers were written in the old 4.2BSD style with
1508 sigblock and sigmask and so forth, and this led to some
1509 inefficiencies and confusion. Rewrite these to use
1510 pthread_sigmask etc. without copying signal sets around. Also,
1511 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
1512 'signal', and instead use functions that do not attempt to take
1513 over the system name space. This patch causes Emacs's text
1514 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
1515 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
1516 Do not include <signal.h> or "syssignal.h", as these
1517 modules do not use signals.
1518 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
1519 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
1520 Do not include <signal.h>, as "syssignal.h" does that for us now.
1521 * atimer.c (sigmask_atimers): New function.
1522 (block_atimers, unblock_atimers): New functions,
1523 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
1525 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
1526 no longer needed here.
1527 * emacs.c (main): Inspect existing signal handler with sigaction,
1528 so that there's no need to block and unblock SIGHUP.
1529 * sysdep.c (struct save_signal): New member 'action', replacing
1530 old member 'handler'.
1531 (save_signal_handlers, restore_signal_handlers):
1532 Use sigaction instead of 'signal' to save and restore.
1533 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
1534 New function. All users of 'signal' modified to use set_sighandler
1535 if they're writeonly, and to use sys_signal if they're read+write.
1536 (emacs_sigaction_init, forwarded_signal): New functions.
1537 (sys_signal): Remove. All uses replaced by calls to sigaction
1538 and emacs_sigaction_init, or by direct calls to 'signal'.
1539 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
1540 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
1541 all uses replaced by pthread_sigmask etc. calls.
1542 * syssignal.h: Include <signal.h>.
1543 (emacs_sigaction_init, forwarded_signal): New decls.
1544 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
1545 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
1546 (sigmask, sys_sigmask): Remove; no longer needed.
1547 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
1548 (sigblock, sigunblock, sigfree):
1549 (sigsetmask) [!defined sigsetmask]:
1550 Remove. All uses replaced by pthread_sigmask.
1551 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
1552 no longer need to be replaced, and its typical old uses
1553 are now done via emacs_sigaction_init and sigaction.
1554 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
1555 (sys_sigdel): Remove; unused.
1556 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
1558 2012-09-06 Eli Zaretskii <eliz@gnu.org>
1560 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
1561 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
1563 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1565 Explicitly mark buffer_defaults and buffer_local_symbols.
1566 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
1567 mark_local_symbols here.
1568 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
1569 since special buffers aren't marked here any more.
1570 (allocate_buffer): Chain new buffer with all_buffers here...
1571 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
1573 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
1574 (syms_of_buffer): Remove staticpro of the above.
1575 (init_buffer_once): Set names for buffer_defaults and
1576 buffer_local_symbols.
1578 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1580 Use bool for booleans in font-related modules.
1581 * font.c (font_intern_prop, font_style_to_value)
1582 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
1583 (generate_otf_features, font_check_otf_features, font_check_otf)
1584 (font_match_p, font_list_entities, font_at):
1585 * fontset.c (fontset_id_valid_p, reorder_font_vector
1586 (fontset_find_font, Fset_fontset_font)
1587 (face_suitable_for_char_p) [0]:
1588 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
1589 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
1590 (m17n_flt_initialized, ftfont_shape_by_flt):
1591 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
1592 * nsfont.m (nsfont_draw):
1593 * w32font.c (w32font_draw):
1594 * w32term.c (x_draw_glyphless_glyph_string_foreground):
1595 Use bool for booleans.
1596 * font.h: Adjust to above API changes.
1597 (struct font, struct font_driver, struct font_driver_list):
1598 Use bool for booleans.
1599 (struct font): Remove useless member encoding_type.
1601 * fontset.c, xftfont.c: Omit unnecessary static decls.
1603 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1605 * alloc.c (mark_object): Revert window marking code
1606 since it's unsafe for the Fset_window_configuration.
1608 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1610 Fix race conditions with signal handlers and errno (Bug#12327).
1611 Be more systematic about preserving errno whenever a signal
1612 handler returns, even if it's not in the main thread. Do this by
1613 renaming signal handlers to distinguish between signal delivery
1614 and signal handling. All uses changed.
1615 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
1616 * data.c (deliver_arith_signal): Rename from arith_error.
1617 * dispnew.c (deliver_window_change_signal): Rename from
1618 window_change_signal.
1619 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
1620 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
1621 * keyboard.c (deliver_input_available_signal): Rename from
1622 input_available_signal.
1623 (deliver_user_signal): Rename from handle_user_signal.
1624 (deliver_interrupt_signal): Rename from interrupt_signal.
1625 * process.c (deliver_pipe_signal): Rename from send_process_trap.
1626 (deliver_child_signal): Rename from sigchld_handler.
1627 * atimer.c (handle_alarm_signal):
1628 * data.c (handle_arith_signal):
1629 * dispnew.c (handle_window_change_signal):
1630 * emacs.c (handle_fatal_signal, handle_danger_signal):
1631 * keyboard.c (handle_input_available_signal):
1632 * keyboard.c (handle_user_signal, handle_interrupt_signal):
1633 * process.c (handle_pipe_signal, handle_child_signal):
1634 New functions, with the actual signal-handling code taken from the
1635 original respective signal handlers, sans the sporadic attempts to
1636 preserve errno, since that's now done by handle_on_main_thread.
1637 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
1638 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
1639 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1641 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1642 Move initialization of main_thread to sysdep.c's init_signals.
1643 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
1644 our usage, and simplifies the mainline code.
1645 (record_child_status_change): New static function, as a helper
1646 for handle_child_signal, and with most of the old child handler's
1648 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
1649 (handle_child_signal): Use the above.
1650 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1651 Moved here from emacs.c.
1652 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
1653 code moved here from emacs.c's main function.
1654 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
1655 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
1656 This lets callers save and restore errno properly.
1658 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1660 Remove redundant or unused things here and there.
1661 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
1662 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
1663 * editfns.c (Fcompare_buffer_substrings): Likewise.
1664 * frame.h (struct terminal, struct font_driver_list):
1665 Remove redundant declarations.
1666 * window.h (Qleft, Qright): Likewise.
1668 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1670 Do not mark objects from deleted buffers, windows and frames.
1671 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
1672 (mark_object): Likewise for windows and frames.
1674 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1676 * alloc.c (valid_lisp_object_p): Treat killed buffers,
1677 buffer_defaults and buffer_local_symbols as valid objects.
1678 Return special value to denote them.
1680 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1682 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
1683 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
1684 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
1685 (file_name_absolute_p, Fsubstitute_in_file_name):
1686 (check_executable, check_writable, Ffile_accessible_directory_p)
1687 (Fset_file_selinux_context, Fdefault_file_modes)
1688 (Finsert_file_contents, choose_write_coding_system)
1689 (Fwrite_region, build_annotations, a_write, e_write)
1691 * filelock.c (boot_time_initialized, get_boot_time)
1692 (get_boot_time_1, lock_file_1, within_one_second):
1693 * floatfns.c (in_float):
1694 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
1695 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
1696 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
1697 * lisp.h (struct Lisp_Hash_Table.cmpfn):
1698 * window.c (compare_window_configurations):
1699 Use bool for booleans.
1700 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
1701 (Fdefault_file_modes): Now mode_t, not int, for modes.
1702 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
1703 (internal_delete_file): Now returns void, not a (boolean) int,
1704 since nobody was looking at the return value.
1705 * lisp.h, window.h: Adjust to above API changes.
1707 * xdisp.c (set_message): Simplify and reindent last change.
1709 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
1711 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
1713 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
1715 * eval.c (call_debugger): Make the function non-static so that we
1716 can call it from set_message.
1718 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
1719 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
1721 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1723 Give more-useful info on a fatal error (Bug#12328).
1724 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
1725 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
1726 of doing the work ourselves.
1727 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
1728 do most of the work.
1729 (fatal_error_backtrace): New function, taken from the guts
1730 of the old fatal_error_signal, but with a new option to output
1732 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
1733 info about the signal than just its number.
1734 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
1735 * sysdep.c: Include <execinfo.h>
1736 (emacs_backtrace): New function, taken partly from the previous
1737 code of the 'die' function.
1738 (emacs_abort): Call fatal_error_backtrace rather than abort.
1740 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
1742 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
1743 eager (load-time) macro-expansion.
1744 * lisp.mk (lisp): Add macroexp.
1746 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1748 Simplify redefinition of 'abort' (Bug#12316).
1749 Do not try to redefine the 'abort' function. Instead, redo
1750 the code so that it calls 'emacs_abort' rather than 'abort'.
1751 This removes the need for the NO_ABORT configure-time macro
1752 and makes it easier to change the abort code to do a backtrace.
1753 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
1754 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
1755 Remove; sysdep.c's emacs_abort now takes its place.
1756 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
1757 'abort' changed to use 'emacs_abort'.
1758 * msdos.c (dos_abort) [defined abort]: Remove; not used.
1759 (abort) [!defined abort]: Rename to ...
1760 (emacs_abort): ... new name.
1761 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
1762 the place of the old 'abort' in emacs.c.
1763 * w32.c, w32fns.c (abort): Do not #undef.
1764 * w32.c (emacs_abort): Rename from w32_abort.
1766 2012-09-04 Eli Zaretskii <eliz@gnu.org>
1768 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
1769 offsets[j].dv, since the y axis of the screen coordinates points
1770 down, while the y axis of the font definition coordinates points
1771 up. This fixes display of Arabic diacritics such as KASRA and
1772 KASRATAN. (Bug#11860)
1774 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1776 Be more systematic about _setjmp vs setjmp.
1777 * alloc.c (test_setjmp, mark_stack):
1778 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
1779 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
1780 (png_load, my_error_exit, jpeg_load):
1781 * process.c (send_process_trap, send_process):
1782 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
1783 The underscored versions are up to 30x faster on some hosts.
1784 Formerly, the code used setjmp+longjmp sometimes and
1785 _setjmp+_longjmp at other times, with no particular reason to
1786 prefer setjmp+longjmp.
1788 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
1790 Fix minor problem found by static checking.
1791 * buffer.c (Fdelete_all_overlays): Return nil.
1793 2012-09-03 Martin Rudalics <rudalics@gmx.at>
1795 * buffer.c (Fdelete_all_overlays): New function.
1797 2012-09-03 Chong Yidong <cyd@gnu.org>
1799 * gtkutil.c: Add extern decl for Qxft.
1801 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

1920 offset adjustment values separately for each cluster. (Bug#11860)
1922 * image.c: Restore mistakenly removed inclusion of w32.h. Without
1923 it, GCC doesn't see prototypes of w32_delayed_load, and complains
1924 about implicit conversions from integer to pointer.
1926 2012-09-01 Daniel Colascione <dancol@dancol.org>

1982 window system declarations.
1984 * frame.h: Move common functions here: set_frame_menubar,

2247 detection of uninitialized objects from spare memory as live.
2249 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
2252 * Makefile.in (.PHONY): versioclean -> versionclean.
2254 Remove unused external symbols.
2255 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
2256 * window.c (Qwindow_valid_p, decode_valid_window):
2257 Now static, not extern.
2258 * data.c (Qinterval): Remove; unused.
2259 (syms_of_data): Do not define 'interval'.
2260 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
2261 * window.h (decode_valid_window):
2264 * character.c, charset.c, chartab.c: Use bool for booleans.
2265 * character.c (lisp_string_width, string_count_byte8)
2266 (string_escape_byte8):
2267 * charset.c (charset_map_loaded, load_charset_map, read_hex):
2268 (load_charset_map_from_file, map_charset_chars)
2269 (Fdefine_charset_internal, define_charset_internal)
2270 (Fdeclare_equiv_charset, find_charsets_in_text)
2271 (Ffind_charset_region, char_charset, Fiso_charset):
2272 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
2273 (sub_char_table_set, sub_char_table_set_range)
2274 (char_table_set_range, optimize_sub_char_table)
2275 (map_sub_char_table):
2276 Use bool for boolean.
2277 * character.c (str_to_unibyte): Omit last boolean argument; it was
2278 always 0. All callers changed.
2279 * character.h, charset.h: Adjust to match previous changes.
2280 * character.h (char_printable_p): Remove decl of nonexistent function.
2281 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
2282 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
2283 are all boolean, so make them single-bit bitfields.
2285 * lisp.h (ASET): Remove attempt to detect side effects.
2286 It was meant to be temporary and it often doesn't work,
2287 because when IDX has side effects the behavior of IDX==IDX
2288 is undefined. See Stefan Monnier in
2289 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
2291 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
2293 * lisp.h (functionp): New function (extracted from Ffunctionp).
2294 (FUNCTIONP): Use it.
2295 * eval.c (Ffunctionp): Use it.
2297 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
2299 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
2300 as that's faster and simpler than static storage. Don't bother
2301 with the g_main_context_query overhead if g_main_context_pending
2302 says no events are pending.
2303 (gfds, gfds_size): Remove these static vars.
2304 (xgselect_initialize): Remove; no longer needed.
2305 All uses and decls removed.
2307 * emacs.c (fatal_error_signal_hook): Remove.
2308 All uses removed. This leftover from old code was always 0.
2310 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
2311 * casefiddle.c (casify_object, casify_region):
2312 * casetab.c (set_case_table):
2313 * category.c, category.h (word_boundary_p):
2314 * category.h (CHAR_HAS_CATEGORY):
2315 Use bool for booleans, instead of int.
2317 2012-08-25 Eli Zaretskii <eliz@gnu.org>
2319 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
2321 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
2323 On assertion failure, print backtrace if available.
2324 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
2325 (die) [ENABLE_CHECKING]: Print a backtrace if available.
2326 * Makefile.in (LIB_EXECINFO): New macro.
2329 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
2330 * bytecode.c (exec_byte_code):
2331 * callint.c (check_mark, Fcall_interactively):
2332 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
2333 (getenv_internal, sync_process_alive, call_process_exited):
2334 * lisp.h (USE_SAFE_ALLOCA):
2335 Use bool for booleans, instead of int.
2336 * lisp.h, process.h: Adjust prototypes to match above changes.
2337 * callint.c (Fcall_interactively): Don't assume the mark's
2338 offset fits in 'int'.
2340 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
2342 * buffer.c, buffer.h: Use bool for boolean.
2343 * buffer.c (reset_buffer_local_variables)
2344 (buffer_lisp_local_variables, Fset_buffer_modified_p)
2345 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
2346 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
2347 (overlay_touches_p, overlay_strings, Foverlay_put)
2348 (report_overlay_modification, call_overlay_mod_hooks):
2349 (mmap_enlarge, mmap_set_vars):
2350 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
2351 Use bool for booleans, instead of int.
2352 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
2353 since the 1-or-0 return value is always ignored anyway.
2354 (mmap_initialized_p):
2355 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
2356 * buffer.h, lisp.h: Adjust prototypes to match above changes.
2358 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
2360 * bidi.c: Use bool for boolean.
2361 This is a bit more readable, and makes the text segment of bidi.o
2362 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
2363 Presumably it's faster too.
2364 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
2366 (bidi_cache_find_level_change, bidi_cache_iterator_state)
2367 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
2368 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
2369 (bidi_explicit_dir_char, bidi_level_of_next_char)
2370 (bidi_find_other_level_edge, bidi_move_to_visually_next):
2371 Use bool for booleans, instead of int.
2372 * dispextern.h (bidi_init_it, bidi_paragraph_init)
2373 (bidi_unshelve_cache): Adjust decls to match code.
2375 2012-08-23 Martin Rudalics <rudalics@gmx.at>
2377 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
2380 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
2382 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
2383 * atimer.h: Include <stdbool.h>.
2385 2012-08-22 Dan Nicolaescu <dann@gnu.org>
2387 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
2388 compile time tests instead of run time tests on systems that do
2390 (FRAME_MAC_P): Remove leftover from deleted code.
2391 * frame.c (syms_of_frame): Remove leftover from deleted code.
2393 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
2395 * nsterm.m (insertText:): Don't clear modifiers if code is space.
2397 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
2399 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
2400 Otherwise, the compiler complains about (A?B:C) where B is void
2401 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
2402 (fontset_add): Return void, for FONTSET_ADD.
2404 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2406 * alloc.c: Use bool for booleans.
2407 (gc_in_progress, abort_on_gc)
2408 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
2409 (dont_register_blocks) [GC_MALLOC_CHECK]:
2410 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
2411 (check_string_bytes, make_specified_string, memory_full)
2412 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
2413 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
2414 (mark_stack, valid_pointer_p, make_pure_string)
2415 (Fgarbage_collect, survives_gc_p, gc_sweep):
2416 Use bool for booleans, instead of int.
2417 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
2418 Remove unused local.
2419 * alloc.c (PURE_POINTER_P):
2420 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
2421 * editfns.c (Fformat):
2422 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
2424 * fns.c (sweep_weak_table):
2425 * lisp.h (suppress_checking, push_message, survives_gc_p)
2426 (make_pure_string, gc_in_progress, abort_on_gc):
2427 * lread.c (readchar, read1):
2428 * print.c (Fprin1_to_string):
2429 * xdisp.c (push_message):
2430 Use bool for booleans affected directly or indirectly by
2433 Make recently-introduced setters macros.
2434 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
2435 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
2436 (set_fontset_default, set_fontset_fallback): Rename from their
2437 upper-case counterparts, and make them functions rather than macros.
2438 This is more consistent with the other recently-introduced setters.
2439 These don't need to be inline, since they're local.
2441 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
2443 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
2444 the loop (Bug#12247).
2446 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2448 * lisp.h (vcopy): Use memcpy rather than our own loop.
2449 This fixes a performance regression introduced by the recent
2450 addition of vcopy. This means 'vcopy' will need to be modified
2451 for a copying collector, but that's OK. Also, tighten the
2452 checking in the assertion.
2454 2012-08-21 Eli Zaretskii <eliz@gnu.org>
2456 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
2457 components for RTL text (Bug#11860). Adjust X-OFFSET of each
2458 non-base glyph for the width of the base character, according to
2459 what x_draw_composite_glyph_string_foreground expects.
2460 Generate WADJUST value according to composition_gstring_width's
2461 expectations, to produce correct width of the composed character.
2462 Reverse the sign of the DU offset produced by ScriptPlace.
2464 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2466 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
2468 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2470 Avoid direct writes to contents member of struct Lisp_Vector.
2471 * lisp.h (vcopy): New function to copy data into vector.
2472 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
2473 * fns.c (Ffillarray): Use ASET.
2474 * keyboard.c (timer_check_2): Use AREF and ASET.
2475 (append_tool_bar_item, Frecent_keys): Use vcopy.
2476 * lread.c (read_vector): Use ASET.
2477 * msdos.c (Frecent_doskeys): Use vcopy.
2478 * xface.c (Finternal_copy_lisp_face): Use vcopy.
2479 (Finternal_merge_in_global_face): Use ASET and vcopy.
2480 * xfont.c (xfont_list_pattern): Likewise.
2482 2012-08-21 Martin Rudalics <rudalics@gmx.at>
2484 * window.c (Fwindow_point): For the selected window always return
2485 the position of its buffer's point.
2486 (Fset_window_point): For the selected window always go in its
2487 buffer to the specified position.
2489 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2491 Setter macros for fontsets.
2492 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
2493 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
2494 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
2497 2012-08-20 Glenn Morris <rgm@gnu.org>
2499 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
2500 Don't assume that `ln -f' works.
2502 2012-08-20 Eli Zaretskii <eliz@gnu.org>
2504 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
2505 and later about non-assignments with no effect. See discussion at
2506 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
2509 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2511 Inline setter functions for Lisp_Objects slots of struct specbinding.
2512 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
2515 2012-08-20 Martin Rudalics <rudalics@gmx.at>
2517 * window.c (select_window): Always make selected window's buffer
2520 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2522 Use AREF and ASET for docstrings of category tables.
2523 * category.h (CATEGORY_DOCSTRING): Use AREF.
2524 (SET_CATEGORY_DOCSTRING): Use ASET.
2525 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
2527 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2529 Inline setter functions for hash table members.
2530 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
2531 (set_hash_hash, set_hash_index): Rename with _slot suffix.
2532 (set_hash_key_and_value, set_hash_index, set_hash_next)
2533 (set_hash_hash): New functions.
2534 * charset.c, fns.c: Adjust users.
2536 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2538 Inline getter and setter functions for per-buffer values.
2539 * buffer.h (per_buffer_default, set_per_buffer_default)
2540 (per_buffer_value, set_per_buffer_value): New functions.
2541 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
2542 * buffer.c, data.c: Adjust users.
2544 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
2546 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
2548 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
2550 Rely on <config.h> + <unistd.h> to declare 'environ',
2551 as gnulib does this if the system doesn't.
2552 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
2553 Remove declaration. MS-Windows declares it on stdlib.h which is
2554 included by conf_post.h.
2555 * emacs.c (environ) [DOUG_LEA_MALLOC]:
2556 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
2557 * vm-limit.c: Include <unistd.h>, for 'environ'.
2559 * unexaix.c, unexcoff.c: Include "mem-limits.h".
2560 (start_of_data): Remove decl; mem-limits.h provides it.
2562 * xdisp.c (handle_invisible_prop): Make it a bit faster
2563 and avoid a gcc -Wmaybe-uninitialized diagnostic.
2565 2012-08-19 Chong Yidong <cyd@gnu.org>
2567 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
2570 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
2572 * .gdbinit: Use call instead of set when calling a function in the
2575 * data.c (set_internal): Don't use set_blv_found.
2576 (Fkill_local_variable): Likewise.
2578 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
2580 * nsfont.m (ns_ascii_average_width): Ensure the string
2581 ascii_printable is initialized with a null-terminated character
2582 array. Otherwise, it can contain undesired extra characters.
2584 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
2586 port new setting code to Sun C 5.8 2005/10/13
2587 * chartab.c, lisp.h (char_table_set, char_table_set_range):
2588 Return void, not Lisp_Object. Otherwise, the compiler
2589 complains about (A?B:C) where B is void and C is Lisp_Object
2590 when compiling CHAR_TABLE_SET, due to the recent change to
2591 the API of sub_char_table_set_contents.
2593 2012-08-18 Chong Yidong <cyd@gnu.org>
2595 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
2596 for the string case (Bug#3874).
2598 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
2600 * buffer.h (BSET): Remove (Bug#12215).
2601 Replace all uses with calls to new setter functions.

2631 New setter functions.
2633 * process.h (PSET): Remove (Bug#12215).

2648 * window.h (WSET): Remove (Bug#12215).
2649 Replace all uses with calls to new setter functions.
2650 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.

2670 New setter functions.
2672 * termhooks.h (TSET): Remove (Bug#12215).
2673 Replace all uses with calls to new setter functions.
2674 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
2675 (TERMHOOKS_INLINE): New macro.
2676 (tset_charset_list, tset_selection_alist): New setter functions.
2677 * terminal.c (TERMHOOKS_INLINE):

3428 value of EMACSLOADPATH, as it is no longer needed.
3429 (check_windows_init_file): Now external, not static.
3430 Use Vload_path as is, without adding anything, as this function is now
3431 called when Vload_path is already set up.

3435 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

3480 * alloc.c (record_xmalloc): New function.
3481 * lisp.h (record_xmalloc): New decl.
3482 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
3483 more like a function. This is because the pointer cast is not
3484 needed. All uses changed.
3485 * print.c (print_string, print_error_message): Avoid length recalc.
3487 Improve fix for macroexp crash with debugging (Bug#12118).
3488 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
3489 ARRAY_MARK_FLAG when checking subscripts, because ASET is
3490 not supposed to be invoked from the garbage collector.

3492 (gc_aset): New function, which is like ASET but can be
3493 used in the garbage collector.

3522 with addition of handling of symlinks and support for 'lstat'.
3523 If possible, get file's attributes and security information by
3524 handle, not by name. Produce S_IFLNK bit for symlinks, when
3525 called from 'lstat'.
3526 (stat, lstat): New functions, call 'stat_worker'.
3527 (symlink, readlink, careadlinkat): Rewritten to create and resolve
3528 symlinks when the underlying filesystem supports them.
3530 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
3532 Fix macroexp crash on Windows with debugging (Bug#12118).
3533 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
3534 checking subscripts; problem introduced with the recent
3535 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
3536 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
3537 since it's used in non-static inline functions now.
3539 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
3540 Don't assume buffer size fits in 'int'. Remove unused local.

4028 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
4030 Improve GDB symbol export (Bug#12036).
4031 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
4032 arms of an 'if', not using conditional expressions; otherwise GDB
4033 complains about the types in the unevaluated arm when the argument
4034 is an integer literal.
4035 (xgetint): Simplify expression.
4036 * alloc.c (gdb_make_enums_visible): New constant. This ports to
4037 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
4038 Zaretskii in <http://bugs.gnu.org/12036#13>.
4039 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
4040 needed now that we have gdb_make_enums_visible.
4041 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
4042 (enum enum_USE_LSB_TAG):
4043 New enum types, packaging up enums that need to be exported to GDB.
4045 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
4047 Utility function to make a list from specified amount of objects.

4062 * xfns.c (syms_of_xfns): Likewise.
4064 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
4066 Fast save_excursion_save and save_excursion_restore.
4067 * lisp.h (struct Lisp_Excursion): New data type.
4068 (PVEC_EXCURSION): New pseudovector type.
4069 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
4070 to deal with it. Adjust comments.
4071 (init_marker, attach_marker): New prototype.
4072 (unchain_marker): Adjust prototype.

4081 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
4083 Fix export of symbols to GDB (Bug#12036).
4084 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
4085 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
4086 emacs.c, as this is a more-suitable home. Had this been done earlier
4087 the fix for 12036 would have avoided some of the problems noted in
4088 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
4089 would have been more obvious.
4090 * emacs.c: Do not include <verify.h>; no longer needed.
4091 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
4092 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
4093 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
4094 Remove; now done in lisp.h.
4095 * lisp.h (PUBLISH_TO_GDB): New macro.
4096 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
4097 (DATA_SEG_BITS): Use it.
4098 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
4099 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
4100 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
4101 not be usable in #if. This simplifies things.
4103 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
4105 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
4107 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
4109 Simplify export of symbols to GDB (Bug#12036).
4110 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
4111 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
4112 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
4113 Adjust to changes in lisp.h and emacs.c, by using
4114 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
4115 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
4116 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
4117 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
4118 instead of gdb_valbits.
4119 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
4120 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
4121 instead of gdb_array_mark_flag.
4122 (xboolvector): Get size from $->size, not $->header.size.
4123 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
4124 (xreload, hook-run, hookpost-run): Remove.
4125 * emacs.c: Include <verify.h>.
4126 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
4127 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
4129 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
4130 (gdb_USE_LSB_TAG): New enum constants.
4131 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
4132 Also define these as enum constants, so they're visible to GDB.
4133 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
4134 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
4135 as constants, so they're visible to GDB.
4136 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
4137 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
4138 Now enum constants, not macros, so they're visible to GDB.
4139 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
4140 more convenient now. All uses changed.
4141 (VALMASK) [USE_LSB_TAG]: Also define in this case.
4142 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
4144 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

4149 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
4151 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
4152 add argument, tune behavior, and adjust all callers.
4154 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
4156 Use typedef for EMACS_INT, EMACS_UINT.
4157 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
4158 than macros. This simplifies debugging in the usual case, since
4159 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
4160 and it allows expressions involving EMACS_INT casts.
4161 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
4163 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

4173 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
4175 Adjust buffer text indirection counters at the end of Fkill_buffer.
4176 * buffer.c (Fkill_buffer): Adjust indirection counters when the
4177 buffer is definitely dead. This should really fix an issue reported
4178 by Christoph Scholtes again. (Bug#12007).
4179 (init_buffer_once): Initialize indirection counters of
4180 buffer_defaults and buffer_local_symbols (for sanity and safety).
4182 2012-07-24 Eli Zaretskii <eliz@gnu.org>
4184 * xdisp.c (init_iterator): Don't compute dimensions of truncation
4185 and continuation glyphs on tooltip frames, leave them at zero.
4186 Avoids continued lines in tooltips. (Bug#11832)
4188 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>

4213 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
4215 Swap buffer text indirection counters in Fbuffer_swap_text.
4216 * buffer.c (Fbuffer_swap_text): Swap indirections too.
4217 This avoids crash reported by Christoph Scholtes at
4218 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
4220 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
4222 * nsmenu.m (Popdown_data): New struct.

4227 and autorelease them. Also autorelease img and matrix (Bug#12005).
4228 (dealloc): Remove (Bug#12005).

4245 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
4247 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
4248 as it's limited by the amount of memory, not by INT_MAX.
4250 2012-07-21 Eli Zaretskii <eliz@gnu.org>
4252 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
4253 in special-event-map. See the discussion at

4334 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
4335 'for_each_per_buffer_object_at'.
4336 All uses changed. It's better to use upper-case for macros that
4337 cannot be implemented as functions, to give the reader a clue
4338 that they're special.
4340 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>

4383 * intervals.c (merge_interval_right, merge_interval_left):
4384 Do not zero out this interval if it is absorbed by its children,
4385 as this interval's total length doesn't change in that case. See
4386 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
4388 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
4390 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
4391 when invoking (make-bool-vector N t) and N is a positive

4395 * alloc.c (bool_header_size): New constant.
4396 (header_size, word_size): Move earlier, as they're now used earlier.

4399 padding before the data member of a bool vector.
4400 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
4401 than doing the check by hand with an abort ().
4403 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
4405 * eval.c (Fdefvar): Don't check constants since we only set the var if
4406 it's not yet defined anyway (bug#11904).
4408 * lisp.h (last_undo_boundary): Declare new var.
4409 * keyboard.c (command_loop_1): Set it.
4410 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
4411 were auto-added by the command loop (bug#11774).
4413 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
4415 * w32font.c (Qsymbol): Remove local definition.

4904 2012-07-11 Glenn Morris <rgm@gnu.org>
4906 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
4907 since nothing has defined it on these platforms.
4909 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/gnu-linux.h:
4910 * s/irix6-5.h: Move SIGNALS_VIA_CHARACTERS to configure.

4914 Move CLASH_DETECTION to configure.
4916 * s/gnu.h: Remove file, which is now empty.
4918 * s/gnu.h, s/gnu-linux.h:
4919 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
4921 2012-07-11 John Wiegley <johnw@newartisans.com>
4923 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
4924 function attribute, so we only use it if it exists in the
4927 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
4929 Avoid call to strlen in fast_c_string_match_ignore_case.
4930 * search.c (fast_c_string_match_ignore_case): Change to use
4931 length argument. Adjust users accordingly.
4932 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
4934 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

4951 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
4953 Avoid calls to strlen in font processing functions.
4954 * font.c (font_parse_name, font_parse_xlfd, font_parse_fcname)
4955 (font_open_by_name): Change to use length argument.
4956 Adjust users accordingly.
4957 * font.h (font_open_by_name, font_parse_xlfd, font_unparse_xlfd):
4959 * xfont.c (xfont_decode_coding_xlfd, font_unparse_xlfd):
4960 Change to return ptrdiff_t.
4961 (xfont_list_pattern, xfont_match): Use length returned by
4962 xfont_decode_coding_xlfd.

4973 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
4975 Remove "#define unix" that is no longer needed (Bug#11905).
4976 * s/aix4-2.h (unix): Remove; no longer needed.
4978 EMACS_TIME simplification (Bug#11875).
4979 This replaces macros (which typically do not work in GDB)
4980 with functions, typedefs and enums, making the code easier to debug.
4981 The functional style also makes code easier to read and maintain.
4982 * systime.h: Include <sys/time.h> on all hosts, not just if
4983 WINDOWSNT, since 'struct timeval' is needed in general.
4984 (EMACS_TIME): Now a typedef, not a macro.
4985 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
4987 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

4989 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
4990 (EMACS_TIME_LE): Now functions, not macros.
4991 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
4992 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
4993 which are not functions. All uses rewritten to use:
4994 (make_emacs_time): New function.
4995 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
4996 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
4997 not functions. All uses rewritten to use the following, respectively:
4998 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
4999 (add_emacs_time, sub_emacs_time): New functions.
5000 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
5001 * fileio.c (Fcopy_file):
5002 * xterm.c (XTflash): Get the current time closer to when it's used.
5003 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

5007 Simplify by avoiding confusing use of strncpy etc.
5008 * doc.c (Fsnarf_documentation):
5009 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
5010 * frame.c (Fmake_terminal_frame):
5011 * gtkutil.c (get_utf8_string):
5013 * nsmenu.m (ns_update_menubar):
5014 * regex.c (regerror):
5015 Prefer memcpy to strncpy and strncat when either will do.
5016 * fileio.c (Fsubstitute_in_file_name):
5017 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
5018 (menu_separator_name_p):
5019 * nsmenu.m (ns_update_menubar):
5020 Prefer memcmp to strncmp when either will do.
5021 * nsterm.m: Include <ftoastr.h>.
5023 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
5024 Prefer snprintf to strncpy.
5025 * nsterm.m (ns_term_init):
5026 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
5027 * nsterm.m (ns_term_init):
5028 Avoid the need for strncpy, by using build_string or
5029 make_unibyte_string directly. Use dtoastr, not snprintf.
5030 * process.c (Fmake_network_process): Diagnose service names that
5031 are too long, rather than silently truncating them or creating
5032 non-null-terminated names.
5033 (Fnetwork_interface_info): Likewise, for interface names.
5034 * sysdep.c (system_process_attributes) [GNU_LINUX]:
5035 Prefer sprintf to strncat.
5036 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
5037 Prefer vsnprintf to vsprintf + strncpy.
5039 2012-07-10 Glenn Morris <rgm@gnu.org>
5041 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
5042 Clarify fallback case.
5044 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
5046 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
5047 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
5048 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
5049 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
5050 where argument type is known to be a Lisp_Cons.
5052 2012-07-10 Tom Tromey <tromey@redhat.com>
5054 * bytecode.c (BYTE_CODE_THREADED): New macro.
5055 (BYTE_CODES): New macro. Replaces all old byte-code defines.
5056 (enum byte_code_op): New type.
5057 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.

5060 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
5062 Optimize pure C strings initialization.
5063 * lisp.h (make_pure_string): Fix prototype.
5064 (build_pure_c_string): New function, defined as static inline. This
5065 provides a better opportunity to optimize away calls to strlen when
5066 the function is called with compile-time constant argument.
5067 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
5068 argument, adjust users accordingly. Use build_pure_c_string where
5070 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
5071 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
5072 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
5074 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
5076 Avoid calls to strlen in miscellaneous functions.
5077 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
5078 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
5079 * lread.c (openp): Likewise.
5081 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
5083 Avoid calls to strlen in path processing functions.
5084 * fileio.c (file_name_as_directory): Add comment. Change to add
5085 srclen argument and return the length of result. Adjust users
5087 (directory_file_name): Fix comment. Change to add srclen argument,
5088 swap 1st and 2nd arguments to obey the common convention.
5089 Adjust users accordingly.
5090 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
5092 2012-07-10 Glenn Morris <rgm@gnu.org>
5094 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
5095 Move PENDING_OUTPUT_COUNT definition to configure.
5097 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
5098 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
5099 * s/gnu.h (DATA_START): Move definitions to configure.
5101 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
5102 We include usg5-4-common.h, which defines them both.
5104 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
5105 O_RDONLY already includes it).
5107 Stop ns builds setting the EMACSLOADPATH environment variable.
5108 * nsterm.m (ns_load_path): Rename from ns_init_paths.
5109 Now it does not set EMACSLOADPATH, just returns the load-path string.
5110 * nsterm.h: Update accordingly.
5111 * lread.c [HAVE_NS]: Include nsterm.h.
5112 (init_lread) [HAVE_NS]: Use ns_load_path.
5113 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
5115 2012-07-09 Glenn Morris <rgm@gnu.org>
5117 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
5118 since the included bsd-common.h does so.
5120 Stop ns builds setting the EMACSPATH environment variable.
5121 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
5122 (ns_init_paths): Do not set EMACSPATH.
5123 * nsterm.h (ns_exec_path): Add it.
5124 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
5127 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
5129 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
5131 * process.c (wait_reading_process_output): 'waitchannels' was unset
5132 when read_kbd || !NILP (wait_for_cell); fix this.
5134 Add GCC-style 'const' attribute to functions that can use it.
5135 * character.h (char_resolve_modifier_mask):
5136 * keyboard.h (make_ctrl_char):
5137 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
5138 (init_character_once, next_almost_prime, init_fns, init_image)
5139 (flush_pending_output, init_sound):
5140 * mem-limits.h (start_of_data):

5144 Declare the dummy function with ATTRIBUTE_CONST.
5145 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
5146 Add decls with ATTRIBUTE_CONST.
5148 Minor improvements to make_formatted_string.
5149 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
5150 where int is good enough, as vsprintf returns an int.
5151 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
5153 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
5155 Use make_formatted_string to avoid double length calculation.
5156 * lisp.h (make_formatted_string): New prototype.
5157 * alloc.c (make_formatted_string): New function.
5158 * buffer.c (Fgenerate_new_buffer_name): Use it.
5159 * dbus.c (syms_of_dbusbind): Likewise.

5162 * frame.c (make_terminal_frame, set_term_frame_name)
5163 (x_report_frame_params): Likewise.
5164 * image.c (gs_load): Likewise.
5165 * minibuf.c (get_minibuffer): Likewise.

5180 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
5182 Move marker debugging code under MARKER_DEBUG.
5183 * marker.c (MARKER_DEBUG): Move marker debugging code under
5184 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
5185 for bootstrap with --enable-checking (~3x slowdown reported
5186 by Juanma Barranquero <lekktu@gmail.com>).
5187 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
5189 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
5191 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
5192 See <http://bugs.gnu.org/11825#29>.
5194 2012-07-08 Eli Zaretskii <eliz@gnu.org>
5196 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
5197 has no font, use the frame's font. (Bug#11813)
5198 (display_line): Add commentary about displaying truncation glyphs
5200 (produce_special_glyphs): Move here from term.c.
5202 * term.c (produce_special_glyphs): Move to xdisp.c.
5204 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
5207 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
5209 * xdisp.c (display_line): Avoid warning about implicit declaration
5212 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
5214 * lisp.h: Remove empty conditional.
5216 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
5218 * lread.c (load_path_check): Now static.
5220 Fix some minor --with-ns problems found by static checking.
5221 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
5222 (x_set_font) [!HAVE_X_WINDOWS]:
5223 * image.c (xpm_load_image) [HAVE_NS]:
5224 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
5225 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
5226 Remove unused local.
5227 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
5228 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
5229 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
5230 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
5231 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
5232 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
5233 Fix pointer signedness problem.
5234 * xfaces.c (FRAME_X_FONT_TABLE):
5235 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
5237 2012-07-07 Glenn Morris <rgm@gnu.org>
5239 * lread.c (load_path_check): New function, split from init_lread.
5240 (init_lread): Reorganize. Motivation:
5241 If EMACSLOADPATH is set, check/warn about that rather than the
5242 defaults, which we are not going to use. Hence we can remove
5243 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
5244 Don't warn if site-lisp directories are missing.
5245 If not installed, start from a blank load-path, since
5246 PATH_LOADSEARCH refers to the eventual installation directories.
5248 2012-07-07 Eli Zaretskii <eliz@gnu.org>
5250 Support truncation and continuation glyphs on GUI frames, when
5251 fringes are disabled. (Bug#11832)
5252 * xdisp.c (init_iterator): Get dimensions of truncation and
5253 continuation glyphs even if on GUI frames.
5254 Adjust it->last_visible_x on GUI frames when the left or right fringes,
5255 or both, are absent.
5256 (start_display, move_it_in_display_line_to): Handle the case of a
5257 GUI frame without a fringe to display continuation or truncation
5259 (insert_left_trunc_glyphs): Support GUI frames: make sure
5260 truncation glyphs overwrite enough glyphs from the current line to
5261 have sufficient space in pixels.
5262 (display_line): Support truncation and continuation glyphs on GUI
5263 frames. If some spare pixels are left on the line after inserting
5264 the truncation glyphs, fill that space with a stretch glyph of a
5265 suitably computed width.
5267 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
5268 produce_glyphs, to support GUI sessions.
5270 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
5272 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
5274 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
5276 Do not require float-time's arg to fit in time_t (Bug#11825).
5277 This works better on hosts where time_t is unsigned, and where
5278 float-time is applied to the (negative) difference between two times.
5279 * editfns.c (decode_time_components): Last arg is now double *,
5280 not int *, and means to store all the result as a double, without
5281 worrying about whether the seconds part fits in time_t.
5282 All callers changed.
5283 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
5284 All callers changed.
5285 (Ffloat_time): Do not fail merely because the specified time falls
5286 outside of time_t range.
5288 2012-07-07 Glenn Morris <rgm@gnu.org>
5290 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

5294 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
5296 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
5297 Update dependencies.
5299 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
5301 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5303 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
5304 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
5305 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
5306 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
5307 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
5308 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
5310 * xfont.c (compare_font_names): Redo to omit the need for casts.
5312 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
5314 * xfns.c (Fx_change_window_property): Doc fix.
5315 * w32fns.c (Fx_change_window_property): Doc fix.
5317 * w32fns.c (Fx_window_property): Accept the same arguments as the
5318 X Windows version. Doc fix.
5319 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
5321 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
5322 Eli Zaretskii <eliz@gnu.org>
5324 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
5325 Windows-specific code from nt/config.nt moved here.
5326 Obsolete settings removed.
5328 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5330 * process.c: Avoid unnecessary calls to gettime.
5331 (wait_reading_process_output): Don't get the time of day
5332 when gobbling data immediately and not waiting, as there's no need
5333 for it in that case. This removes a FIXME.
5335 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
5337 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
5338 is defined (Bug#11768).
5340 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5342 Fix marker debugging code.
5343 * marker.c (byte_char_debug_check): Do not perform the check
5344 if buffer is not multibyte.
5345 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
5346 Call byte_char_debug_check with correct arguments.
5348 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5350 Compile marker debugging code only if ENABLE_CHECKING is defined.
5351 * marker.c (byte_char_debug_check, count_markers):
5352 Use only if ENABLE_CHECKING is defined.
5353 (byte_debug_flag): Remove.
5354 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
5355 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
5357 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5359 Avoid code repetition in marker-related functions.
5360 * marker.c (attach_marker): New function.
5361 (Fset_marker, set_marker_restricted, set_marker_both)
5362 (set_marker_restricted_both): Use it.
5363 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
5364 Consistently rename charno to charpos.
5365 (marker_position): Add eassert.
5366 (marker_byte_position): Convert to eassert.
5368 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5370 Simplify list operations in unchain_overlay and unchain_marker.
5371 * buffer.c (unchain_overlay): Simplify. Add comment.
5372 * marker.c (unchain_marker): Simplify. Fix comments.
5374 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5376 Introduce fast path for the widely used marker operation.
5377 * alloc.c (build_marker): New function.
5378 * lisp.h (build_marker): New prototype.
5379 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
5380 * composite.c (autocmp_chars): Likewise.
5381 * editfns.c (buildmark): Remove.
5382 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
5383 (save_restriction_save): Use build_marker.
5384 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
5385 * window.c (save_window_save): Likewise.
5387 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

5390 to avoid redundant calls to unchain_overlay.
5391 * buffer.c (drop_overlay): New function.
5392 (delete_all_overlays, Fdelete_overlay): Use it.
5393 * minibuf.c (get_minibuffer): Fix comment.
5395 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5397 Port to OpenBSD 5.1 amd64.
5398 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
5399 This is needed for OpenBSD, and should be harmless on all BSD systems.
5400 Also, include <sys/sysctl.h>, as it should be available on all
5401 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
5402 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
5403 use p_pid member, not kp_proc.pid.
5405 2012-07-06 Glenn Morris <rgm@gnu.org>
5407 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
5409 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5411 More xmalloc and related cleanup.
5412 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

5419 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
5420 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
5422 Omit needless casts involving void * pointers and allocation.
5423 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
5424 as the former is more robust if P's type is changed.
5425 Prefer xzalloc to xmalloc + memset 0.
5426 Simplify malloc-or-realloc to realloc.
5427 Don't worry about xmalloc returning a null pointer.
5428 Prefer xstrdup to xmalloc + strcpy.
5429 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
5431 * keyboard.c (apply_modifiers_uncached): Prefer local array to
5432 alloca of a constant.
5434 2012-07-05 Eli Zaretskii <eliz@gnu.org>
5436 * xdisp.c (display_line): Fix horizontal pixel coordinates when
5437 hscroll is larger than the line width. Fixes long and futile
5438 looping inside extend_face_to_end_of_line (on a TTY) producing
5439 glyphs that are not needed and thrown away.
5441 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
5443 * marker.c (set_marker_restricted_both): Simplify by using
5446 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5448 * editfns.c (region_limit): Simplify by using clip_to_bounds.
5450 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
5452 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
5453 not defined (Bug#11768).
5454 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
5455 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
5456 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
5457 followed by gtk_box_set_homogeneous (Bug#11768).
5458 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
5459 (update_theme_scrollbar_width, xg_create_scroll_bar):
5460 Use gtk_scrollbar_new (Bug#11768).
5461 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
5462 (is_box_type): New function (Bug#11768).
5463 (xg_tool_item_stale_p): Call is_box_type.
5464 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
5465 with default display (Bug#11768).
5467 2012-07-05 Eli Zaretskii <eliz@gnu.org>
5469 * xdisp.c (window_hscroll_limited): New function.
5470 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
5471 coordinates when window's hscroll is set to insanely large
5474 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
5476 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
5477 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
5479 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
5482 * lisp.h (xzalloc): New prototype. Omit needless casts.
5483 * alloc.c (xzalloc): New function. Omit needless casts.

5537 * fileio.c (time_error_value): Check the right error number.
5538 Problem reported by Troels Nielsen in
5539 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
5541 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5543 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
5544 This should be fixed in a better way; see Eli Zaretskii in
5545 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
5546 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
5548 * fileio.c (time_error_value): Rename from special_mtime.
5549 The old name's problems were noted by Eli Zaretskii in
5550 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
5552 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
5553 This variable's comment says Emacs needs at least one GDB-visible
5554 symbol of type enum pvec_type, to work around GDB problems.
5555 The symbol's value doesn't matter.
5557 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
5558 that causes compilation to fail on pre-C99 compilers.
5560 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
5562 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
5563 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
5565 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5567 * buffer.c (init_buffer_once): Fix initialization of
5568 headers for buffer_defaults and buffer_local_symbols.
5569 Reported by Juanma Barranquero <lekktu@gmail.com>.
5571 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
5573 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
5574 * lisp.h (enum pvec_type): Use fewer bits.
5575 (PSEUDOVECTOR_SIZE_BITS): New constant.
5576 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
5577 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
5578 change in pvec_type.
5579 (PSEUDOVECTOR_TYPEP): New macro.
5580 (TYPED_PSEUDOVECTORP): Use it.
5581 * fns.c (internal_equal): Adapt code to extract pvectype.
5582 * emacs.c (gdb_pvec_type): Update type.
5583 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
5584 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
5585 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
5586 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
5587 (sweep_vectors): Use it. Use local var `total_bytes' instead of
5588 abusing vector->header.next.nbytes.
5589 (live_vector_p): Use PVEC_TYPE.
5590 (mark_object): Adapt code to extract pvectype. Use switch.
5592 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5594 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
5595 Tighten new eassert a bit.
5597 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5599 Fix compilation with --enable-gcc-warnings and -O1
5601 * doprnt.c (doprnt): Change type of tem to int, initialize
5602 to avoid compiler warning. Add eassert.
5603 * search.c (simple_search): Initialize match_byte to avoid
5604 compiler warning. Add eassert.
5606 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5608 Avoid weird behavior with large horizontal scrolls.
5609 Without this change, for example, large hscroll values would
5610 mess up Emacs's display on Fedora 15 x86, presumably due to
5611 overflows in int calculations in the display code.
5612 Also, if buffers had long lines, Emacs would freeze.
5613 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
5614 (set_window_hscroll): New function, containing the old guts of
5615 Fset_window_hscroll. Return the clipped value.
5616 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
5617 This avoids the need to check against PTRDIFF_MAX.
5619 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
5621 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5623 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
5625 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5627 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
5628 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
5629 since GCC 4.4.6 issues a bogus warning for them.
5631 Fix bugs in file timestamp newness comparisons.
5632 * fileio.c (Ffile_newer_than_file_p):
5633 * lread.c (Fload): Use full timestamp resolution of files,
5634 not just the 1-second resolution, so that files that are only
5635 slightly newer still count as newer.
5636 * fileio.c (Ffile_newer_than_file_p): Don't assume file
5637 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
5639 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
5641 * fileio.c: Improve handling of file time marker. (Bug#11852)
5642 (special_mtime): New function.
5643 (Finsert_file_contents, Fverify_visited_file_modtime):
5644 Use it to set special mtime values consistently.
5646 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
5648 * fileio.c (Finsert_file_contents): Properly handle st_mtime
5649 marker for non-existing file. (Bug#11852)
5651 2012-07-03 Glenn Morris <rgm@gnu.org>
5653 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
5654 and did not make it into globals.h).
5656 2012-07-03 Tom Tromey <tromey@redhat.com>
5658 * window.c (Fset_window_margins, Fset_window_fringes)
5659 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
5660 * textprop.c (Fprevious_property_change): No longer static.
5661 * syntax.c (Fsyntax_table_p): No longer static.

5682 * dispextern.h: Remove EXFUNs.
5683 * intervals.h: Remove EXFUNs.
5684 * fontset.h: Remove EXFUN.
5685 * font.h: Remove EXFUNs.
5686 * dosfns.c (system_process_attributes): Remove EXFUN.
5687 * keymap.h: Remove EXFUNs.
5688 * lisp.h: Remove EXFUNs.
5689 * w32term.h: Remove EXFUNs.
5690 * window.h: Remove EXFUNs.
5691 * xsettings.h: Remove EXFUN.
5692 * xterm.h: Remove EXFUN.
5694 2012-07-03 Glenn Morris <rgm@gnu.org>
5696 * lisp.h (Frandom): Make it visible to C.
5697 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
5698 buffer for invisible buffers. (Bug#1229)
5700 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5702 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
5703 values which aren't power of 2.
5704 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
5705 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
5708 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
5710 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
5712 * alloc.c (mark_object): Revert part of last patch to use `switch'.
5714 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5716 * alloc.c (allocate_vector_block): Remove redundant
5717 calls to mallopt if DOUG_LEA_MALLOC is defined.
5718 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
5719 avoid calls to mallopt if zero_vector is returned.
5721 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5723 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
5724 is enabled, avoid dereferencing NULL current_sblock if
5727 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5729 Cleanup basic buffer management.
5730 * buffer.h (struct buffer): Change layout to use generic vector
5731 marking code. Fix some comments. Change type of 'clip_changed'
5732 to bitfield. Remove unused #ifndef old.
5733 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
5734 (GET_OVERLAYS_AT): Fix indentation.
5735 (for_each_per_buffer_object_at): New macro.
5736 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
5737 (Fbuffer_local_variables): Use it.
5738 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
5739 * alloc.c (allocate_buffer): Adjust to match new layout of
5740 struct buffer. Fix comment.
5741 (mark_overlay): New function.
5742 (mark_buffer): Use it. Use mark_vectorlike to mark normal
5743 Lisp area of struct buffer.
5744 (mark_object): Use it. Adjust marking of misc objects
5745 and related comments.
5747 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
5749 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
5750 wrapper that is not needed because the wrapped code is a no-op (zero
5751 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
5752 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
5754 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
5756 * alloc.c (mark_buffer): Simplify. Remove prototype.
5757 (mark_object): Add comment. Reorganize marking of vector-like
5758 objects. Use CHECK_LIVE for all vector-like objects except buffers
5759 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
5760 Avoid redundant calls to mark_vectorlike for bool vectors.
5762 2012-06-30 Glenn Morris <rgm@gnu.org>
5764 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
5766 * epaths.in (PATH_SITELOADSEARCH): New.
5767 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
5768 This is rather than relying on --enable-locallisppath elements
5769 having "site-lisp" in their names. (Bug#10208#25, 11658)
5771 2012-06-30 Eli Zaretskii <eliz@gnu.org>
5773 * w32proc.c (sys_select): Accept and ignore one more argument.
5775 * w32.c (emacs_gnutls_pull): Call select with one more argument.
5777 * sysselect.h [DOS_NT]: Don't include sys/select.h.
5778 (pselect) [!MS_DOS]: Redirect to sys_select.
5780 * sysdep.c: Don't include dos.h and dosfns.h.
5782 * process.c (sys_select):
5783 * msdos.c (sys_select): Accept one more argument and ignore it.
5785 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
5786 adapt data types and code to that.
5789 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
5790 which clashes with the gnulib function of the same name.
5792 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
5794 * font.c (font_style_to_value, font_style_symbolic)
5795 (font_prop_validate_style): Add type checks for values in
5798 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
5800 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
5803 2012-06-29 Eli Zaretskii <eliz@gnu.org>
5805 * xdisp.c (try_window_id): Undo last change.
5807 * w32.c (getwd): Adjust commentary about startup_dir.
5808 (init_environment): Always call sys_access, even in non-MSVC
5809 builds. Don't chdir to the directory of the Emacs executable.
5810 This undoes code from 1997 which was justified by the need to
5811 "avoid conflicts when removing and renaming directories". But its
5812 downside was that every relative file name was being interpreted
5813 relative to the directory of the Emacs executable, which can never
5814 be TRT. In particular, it broke sys_access when called with
5815 relative file names.
5816 (sys_access): Map GetLastError to errno.
5818 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5820 * window.h (struct window): Change type of 'fringes_outside_margins'

6010 Use sprintf return value instead of invoking strlen on result.
6011 In the old days this wasn't portable, since some sprintf
6012 implementations returned char *. But they died out years ago and
6013 Emacs already assumes sprintf returns int.
6014 Similarly for float_to_string.
6015 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

6023 Use sprintf or float_to_string result to avoid need to call strlen.
6024 * data.c (Fnumber_to_string):
6025 Use make_unibyte_string, since the string must be ASCII.
6026 * lisp.h, print.c (float_to_string): Now returns int length.
6027 * term.c (produce_glyphless_glyph):
6028 Use sprintf result rather than recomputing it.
6030 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
6031 * Makefile.in (ALL_CFLAGS):
6032 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

6061 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
6063 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

6066 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
6068 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
6069 instead of truncating it to 63 (admittedly a generous limit).

6129 * keyboard.c (kbd_buffer_get_event):
6130 * process.c (Faccept_process_output):
6131 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
6132 This improves on the previous patch, which introduced a bug
6133 when time_t is unsigned and as wide as intmax_t.
6134 See <http://bugs.gnu.org/9000#51>.
6136 2012-06-23 Eli Zaretskii <eliz@gnu.org>
6138 * dispnew.c (sit_for, Fsleep_for):

6199 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
6201 Support higher-resolution time stamps (Bug#9000).
6202 The time stamps are only nanosecond-resolution at the C level,
6203 since that's the best that any real-world system supports now.
6204 But they are picosecond-resolution at the Lisp level, as that's
6205 easy, and leaves room for future OS improvements.
6207 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
6210 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
6211 Don't get current time unless it's needed.
6213 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
6214 now provides it if it's absent.
6215 (start_atimer): Port to higher-res time stamps.
6216 Check for time stamp overflow. Don't get current time more
6217 often than is needed.
6219 * buffer.h (struct buffer): Buffer modtime now has high resolution.
6220 Include systime.h, not time.h.
6221 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
6223 * dired.c: Include stat-time.h.
6224 (Ffile-attributes): File times now have higher resolution.
6226 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
6227 (struct image): Timestamp now has higher resolution.
6229 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
6230 has at least microseconds now. All uses removed.
6231 (update_frame, update_single_window, update_window, update_frame_1)
6232 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
6233 (duration_to_sec_usec): Remove; no longer needed.
6235 * editfns.c (time_overflow): Now extern.
6236 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
6237 (float-time, Fformat_time_string, Fcurrent_time_string)
6238 (Fcurrent_time_zone): Accept and generate higher-resolution
6240 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
6241 (decode_time_components, lisp_seconds_argument): New functions.
6242 (make_time): Now static.
6243 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
6244 Report an error if the time is invalid, rather than having the caller
6247 * fileio.c: Include <stat-time.h>
6248 (Fcopy_file): Copy higher-resolution time stamps.
6249 Prefer to set the time stamp via a file descriptor if that works.
6250 (Fset_file_times, Finsert_file_contents, Fwrite_region)
6251 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
6252 (Fvisited_file_modtime, Fset_visited_file_modtime):
6253 Support higher-resolution time stamps.
6255 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
6257 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
6259 * image.c (prepare_image_for_display, clear_image_cache)
6260 (lookup_image): Port to higer-resolution time stamps.
6262 * keyboard.c (start_polling, bind_polling_period):
6263 Check for time stamp overflow.
6264 (read_char, kbd_buffer_get_event, timer_start_idle)
6265 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
6266 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
6267 Port to higher-resolution time stamps. Do not assume time_t is signed.
6268 (decode_timer): New function. Timers are now vectors of length 9,
6269 not 8, to accommodate the picosecond component.
6270 (timer_check_2): Use it.
6272 * nsterm.m (select_timeout, timeval_subtract): Remove.
6273 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
6274 as they're a bit more accurate and handle overflow better.
6275 (ns_select): Change prototype to be compatible with pselect.
6276 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
6277 * nsterm.h (ns_select): Adjust prototype.
6279 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
6280 us-resolution time stamps.
6281 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
6283 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
6285 * lisp.h (time_overflow): New decl.
6286 (wait_reading_process_output): First arg is now intmax_t, not int,
6287 to accommodate larger waits.
6289 * process.h (struct Lisp_Process.read_output_delay):
6290 Now counts nanoseconds, not microseconds.
6291 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
6293 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
6294 (wait_reading_process_output):
6295 Port to ns-resolution time stamps.
6296 (Faccept_process_output, wait_reading_process_output):
6297 Check for time stamp overflow. Do not assume time_t is signed.
6298 (select_wrapper): Remove; we now use pselect.
6299 (Fprocess_attributes): Now generates ns-resolution time stamps.
6301 * sysdep.c: Include utimens.h. Don't include utime.h
6302 or worry about struct utimbuf; gnulib does that for us now.
6303 (gettimeofday): Remove; gnulib provides a substitute.
6304 (make_timeval): New function.
6305 (set_file_times): Now sets ns-resolution time stamps.
6306 New arg FD; all uses changed.
6307 (time_from_jiffies, ltime_from_jiffies, get_up_time)
6308 (system_process_attributes):
6309 Now returns ns-resolution time stamp. All uses changed.
6310 Check for time stamp overflow.
6312 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
6313 provides a substitute now.
6315 * systime.h: Include timespec.h rather than sys/time.h and time.h,
6316 since it guarantees struct timespec.
6317 (EMACS_TIME): Now struct timespec, so that we can support
6318 ns-resolution time stamps.
6319 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
6320 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
6321 (EMACS_USECS): Remove.
6322 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
6323 so multiply the arg by 1000 before storing it.

6326 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

6333 (make_timeval, make_lisp_time, decode_time_components): New decls.
6334 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
6335 that it mishandled time_t overflow. You can't compare by subtracting!
6336 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
6337 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

6365 (timeval_subtract): Remove; no longer needed.
6366 (XTflash, XTring_bell, x_wait_for_event):
6367 Port to ns-resolution time stamps. Don't assume time_t is signed.

6373 2012-06-22 Eli Zaretskii <eliz@gnu.org>
6375 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
6376 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
6377 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
6378 staticidx goes up to 1597 out of 1600 = 0x640.)

6382 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
6383 Otherwise, the umask might be mistakenly 0 while handling input signals.

6416 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
6417 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
6418 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
6419 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

6428 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
6429 gets killed during executing of this function (Bug#11665).
6430 Try to always return Qt when the buffer has been actually killed.
6431 (Vkill_buffer_query_functions): In doc-string say that functions
6432 run by this hook should not change the current buffer.
6434 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

6459 argument were confusing, as 'eassert' typically does not evaluate
6462 * coding.c (produce_chars): Use ptrdiff_t, not int.
6464 * xterm.c (x_draw_underwave): Check for integer overflow.
6465 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

6783 (all_vectors): Rename to `large_vectors'.
6784 (allocate_vector_from_block, init_vectors, allocate_vector_from_block)
6785 (sweep_vectors): New functions.
6786 (allocate_vectorlike): Return `zero_vector' as the only vector of
6787 0 items. Allocate new vector from block if vector size is less than
6788 or equal to VBLOCK_BYTES_MAX.
6789 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
6790 (init_alloc_once): Add call to init_vectors.
6792 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
6794 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
6796 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
6798 * doprnt.c (doprnt): Truncate multibyte char correctly.
6799 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
6800 would mishandle a string argument "Xc" if X was a multibyte
6801 character of length 2: it would truncate after X's first byte
6802 rather than including all of X.
6804 2012-06-06 Chong Yidong <cyd@gnu.org>
6806 * buffer.c (word_wrap): Doc fix.
6808 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

6826 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
6829 2012-06-03 Chong Yidong <cyd@gnu.org>
6831 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
6832 (note_mode_line_or_margin_highlight): If there is no help echo,
6833 use mode-line-default-help-echo. Handle the case where the mouse
6834 position is past the end of the mode line string.
6836 * buffer.c (buffer_local_value_1): New function, split from
6837 Fbuffer_local_value; can return Qunbound.
6838 (Fbuffer_local_value): Use it.
6839 (Vmode_line_format): Docstring tweaks.
6841 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
6843 * sysdep.c (system_process_attributes): Improve comment.
6845 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
6847 * keyboard.c: Export real-this-command to Elisp.
6848 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
6849 and DEFVAR it. Update all users.
6851 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
6853 * minibuf.c (Fassoc_string): Remove duplicate declaration.
6855 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
6856 Convert pctcpu and pctmem to Lisp float properly.
6857 Let the compiler fold better, as 100.0/0x8000 is exact.
6859 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
6861 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
6864 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
6866 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
6868 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
6870 For a 'struct window', replace some Lisp_Object fields to
6871 bitfields where appropriate, remove unused fields.
6872 * window.h (struct window): Remove unused 'last_mark_x' and
6873 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
6874 change it's type from Lisp_Object to bitfield.
6875 Change type of 'force_start', 'optional_new_start',
6876 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
6877 fields from Lisp_Object to bitfield. Adjust users accordingly.
6879 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6881 Pacify gcc -Wdouble-precision when using Xaw.
6882 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
6883 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
6884 Use 'float' consistently, rather than 'float' in most places
6885 and 'double' in a couple of places.
6887 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6889 * xdisp.c (handle_stop): Detect whether we have overlay strings
6890 loaded by testing it->current.overlay_string_index to be
6891 non-negative, instead of checking whether n_overlay_strings is
6892 positive. (Bug#11587)
6894 2012-05-31 Chong Yidong <cyd@gnu.org>
6896 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
6898 * doc.c (Fsubstitute_command_keys): Doc fix.
6900 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6902 * search.c (search_buffer): Remove calls to
6903 r_alloc_inhibit_buffer_relocation, as it is now called by
6904 maybe_unify_char, which was the cause of relocation of buffer text
6907 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6909 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
6910 for the duration of call to load_charset, to avoid problems with
6911 callers of maybe_unify_char that access buffer text through C
6914 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
6915 decrement the inhibition flag, instead of just setting or
6918 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6920 Remove obsolete '#define static' cruft.
6921 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
6922 This #undef was "temporary" in 2000; it is no longer needed
6923 now that '#define static' has gone away.
6924 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
6925 (gray_bitmap_bits): Remove; no longer needed.
6926 All uses replaced with definiens.
6927 * xterm.c: Include "bitmaps/gray.xbm".
6929 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6931 Clean up __executable_start, monstartup when --enable-profiling.
6932 The following changes affect the code only when profiling.
6933 * dispnew.c (__executable_start): Rename from safe_bcopy.
6934 Define only on platforms that need it.
6935 * emacs.c: Include <sys/gmon.h> when profiling.
6936 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
6937 (__executable_start): Remove decl, since lisp.h does it now.
6938 (safe_bcopy): Remove decl; no longer has that name.
6939 (main): Coalesce #if into single bit of code, for simplicity.
6940 Cast pointers to uintptr_t, since standard libraries want integers
6942 * lisp.h (__executable_start): New decl.
6944 2012-05-31 Glenn Morris <rgm@gnu.org>
6946 * image.c (Fimagemagick_types): Doc fix.
6948 2012-05-30 Jim Meyering <meyering@redhat.com>
6950 * callproc.c (Fcall_process_region): Include directory component
6951 in mkstemp error message (Bug#11586).

6961 (Fautoload): Do the hash-doc more carefully.
6962 * data.c (Fdefalias): Purify definition, except for keymaps.
6963 (Qdefun): Move from eval.c.
6964 * lisp.h (Qdefun): Remove.
6965 * lread.c (read1): Tiny simplification.
6967 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
6969 Do not create empty overlays with the evaporate property (Bug#9642).
6970 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
6971 Bug#9642, but explicitly check that the buffer the overlay would
6972 be moved to is live and rearrange lines to make sure that errors
6973 will not put the overlay in an inconsistent state.
6974 (Fdelete_overlay): Cosmetics.
6976 2012-05-28 Eli Zaretskii <eliz@gnu.org>
6978 * w32term.c (my_bring_window_to_top): New function.
6979 (x_raise_frame): Use handle returned by DeferWindowPos, which
6980 could be different from the original one.
6981 Call my_bring_window_to_top instead of my_set_foreground_window.
6984 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
6985 by calling BringWindowToTop.
6987 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
6988 (WM_EMACS_END): Increase by one.
6990 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
6992 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
6993 This avoids undefined behavior that might cause the eassert
6994 to not catch an out-of-range value.
6996 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
6998 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
6999 Update dependencies.
7001 2012-05-27 Eli Zaretskii <eliz@gnu.org>
7003 * bidi.c (bidi_mirror_char): Fix last change.
7005 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

7008 when referring to sectname field in printf format.
7010 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
7012 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
7013 Only r_alloc_inhibit_buffer_relocation needed to be added;
7014 the others were already declared.
7016 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
7017 before checking whether it's out of range. Put the check inside
7019 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
7021 2012-05-27 Ken Brown <kbrown@cornell.edu>
7023 * callproc.c (Fcall_process): Restore a line that was accidentally
7024 commented out in the 2011-02-13 change (bug#11547).
7026 2012-05-27 Eli Zaretskii <eliz@gnu.org>
7028 * lisp.h [REL_ALLOC]: Add prototypes for external functions
7029 defined on ralloc.c.
7031 * buffer.c [REL_ALLOC]: Remove prototypes of
7032 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
7033 they are now on lisp.h.
7035 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
7037 * search.c (search_buffer): Use it to inhibit relocation of buffer
7038 text while re_search_2 is doing its job, because re_search_2 is
7039 passed C pointers to buffer text. (Bug#11519)
7041 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
7044 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
7045 state after an additional call to move_it_in_display_line_to, keep
7046 the values of it->max_ascent and it->max_descent found for the
7048 (pos_visible_p): Revert the comparison against bottom_y to what it
7049 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
7052 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
7054 Fix coding-related core dumps with gcc -ftrapv.
7055 The code was computing A - B, where A and B are pointers, and B is
7056 random garbage. This can lead to core dumps on platforms that
7057 have special pointer registers, and it also leads to core dumps on
7058 x86-64 when compiled with gcc -ftrapv. The fix is to compute
7059 A - B only when B is initialized properly.
7060 * coding.c (coding_set_source, coding_set_destination): Return void.
7061 (coding_change_source, coding_change_destinations): New functions,
7062 with the old behaviors of coding_set_source and coding_set_destination.
7063 All callers that need an offset changed to use these new functions.
7065 2012-05-26 Glenn Morris <rgm@gnu.org>
7067 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
7069 2012-05-26 Eli Zaretskii <eliz@gnu.org>
7071 Extend mouse support on W32 text-mode console.
7072 * xdisp.c (draw_row_with_mouse_face):
7073 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
7075 * w32console.c: Include window.h.
7076 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
7078 (initialize_w32_display): Initialize mouse-highlight data.
7080 * w32inevt.c: Include termchar.h and window.h.
7081 (do_mouse_event): Support mouse-autoselect-window. When the mouse
7082 moves, call note_mouse_highlight. If help_echo changed, call
7083 gen_help_event to produce help-echo message in the echo area.
7084 Call clear_mouse_face if mouse_face_hidden is set in the mouse
7087 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
7089 * lread.c (read1): Simplify slightly to avoid an overflow warning
7090 with GCC 4.7.0 on x86-64.
7092 2012-05-26 Eli Zaretskii <eliz@gnu.org>
7094 * bidi.c (bidi_mirror_char): Revert last change: an int is
7095 definitely wide enough here.
7097 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
7099 Fix integer width and related bugs (Bug#9874).
7100 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
7101 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
7102 (string_bytes, check_sblock, allocate_string_data):
7103 (compact_small_strings, Fmake_bool_vector, make_string)
7104 (make_unibyte_string, make_multibyte_string)
7105 (make_string_from_bytes, make_specified_string)
7106 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
7107 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
7109 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7110 (allocate_pseudovector):
7111 Use int, not EMACS_INT, where int is wide enough.
7112 (inhibit_garbage_collection, Fgarbage_collect):
7113 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7114 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
7115 int might not be wide enough.
7116 (bidi_cache_search, bidi_cache_find, bidi_init_it)
7117 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
7118 (bidi_at_paragraph_end, bidi_find_paragraph_start)
7119 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
7120 (bidi_level_of_next_char, bidi_move_to_visually_next):
7121 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7122 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
7123 (Fkill_buffer, Fset_buffer_major_mode)
7124 (advance_to_char_boundary, Fbuffer_swap_text)
7125 (Fset_buffer_multibyte, overlays_at, overlays_in)
7126 (overlay_touches_p, struct sortvec, record_overlay_string)
7127 (overlay_strings, recenter_overlay_lists)
7128 (adjust_overlays_for_insert, adjust_overlays_for_delete)
7129 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
7130 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
7131 (Foverlay_recenter, last_overlay_modification_hooks_used)
7132 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
7133 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7134 (validate_region): Omit unnecessary test for b <= e,
7135 since that's guaranteed by the previous test.
7136 (adjust_overlays_for_delete): Avoid pos + length overflow.
7137 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
7138 (report_overlay_modification):
7139 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7140 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
7141 Omit pointer cast, which isn't needed anyway, and doesn't work
7142 after the EMACS_INT -> ptrdiff_t change.
7143 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
7144 * buffer.h: Adjust decls to match defn changes elsewhere.
7145 (struct buffer_text, struct buffer):
7146 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7147 Use EMACS_INT, not int, where int might not be wide enough.
7148 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
7149 not int, to avoid needless 32-bit limit on 64-bit hosts.
7150 (exec_byte_code): Use tighter memory-full test, one that checks
7151 for alloca overflow. Don't compute the address of the object just
7152 before an array, as that's not portable. Use EMACS_INT, not
7153 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
7154 * callint.c (Fcall_interactively):
7155 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7156 * callproc.c (call_process_kill, Fcall_process):
7157 Don't assume pid_t fits into an Emacs fixnum.
7158 (call_process_cleanup, Fcall_process, child_setup):
7159 Don't assume pid_t fits into int.
7160 (call_process_cleanup, Fcall_process, delete_temp_file)
7161 (Fcall_process_region):
7162 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7163 (Fcall_process): Simplify handling of volatile integers.
7164 Use int, not EMACS_INT, where int will do.
7165 * casefiddle.c (casify_object, casify_region, operate_on_word)
7166 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
7167 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7168 (casify_object): Avoid integer overflow when overallocating buffer.
7169 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
7170 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
7171 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
7172 * category.h (CATEGORYP): Don't assume arg is nonnegative.
7173 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
7174 integers are now checked earlier. All uses replaced with XINT.
7176 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7177 For CCL_MapSingle, check that content and value are in int range.
7178 (ccl_driver, Fregister_code_conversion_map):
7179 Check that Vcode_version_map_vector is a vector.
7180 (resolve_symbol_ccl_program): Check that vector header is in range.
7181 Always copy the vector, so that we can check its contents reliably
7182 now rather than having to recheck each instruction as it's being
7183 executed. Check that vector words fit in 'int'.
7184 (ccl_get_compiled_code, Fregister_ccl_program)
7185 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
7186 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
7187 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
7188 contents are in range.
7189 (Fccl_execute_on_string): Check that status is in range.
7190 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
7191 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
7192 Accept and return EMACS_INT, not int, because callers can pass values
7194 (c_string_width, strwidth, lisp_string_width, chars_in_text)
7195 (multibyte_chars_in_text, parse_str_as_multibyte)
7196 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
7197 (str_as_unibyte, str_to_unibyte, string_count_byte8)
7198 (string_escape_byte8, Fget_byte):
7199 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7200 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
7201 avoid mishandling large integers.
7202 * character.h: Adjust decls to match defn changes elsewhere.
7203 * charset.c (load_charset_map_from_file, find_charsets_in_text)
7204 (Ffind_charset_region):
7205 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7206 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
7207 (load_charset_map_from_vector, Fdefine_charset_internal):
7208 Don't assume fixnum fits in int.
7209 (load_charset_map_from_vector, Fmap_charset_chars):
7210 Remove now-unnecessary CHECK_NATNUMs.
7211 (Fdefine_charset_internal): Check ranges here, more carefully.
7212 Don't rely on undefined behavior with signed left shift overflow.
7213 Don't assume unsigned int fits into fixnum, or that fixnum fits
7214 into unsigned int. Don't require max_code to be a valid fixnum;
7215 that's not true for gb10830 4-byte on a 32-bit host. Allow
7216 invalid_code to be a cons, for the same reason. Require code_offset
7217 to be a character. Avoid int overflow if max_char is close
7219 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
7220 this is intended anyway and avoids some undefined behavior.
7221 (load_charset_map): Pass unsigned, not int, as 2nd arg of
7222 INDEX_TO_CODE_POINT, as that's what it expects.

7933 * lisp.h (USE_LSB_TAG):
7934 * mem-limits.h (EXCEEDS_LISP_PTR):
7935 Use VAL_MAX, not VALBITS, in #if.
7936 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
7937 (EMACS_UINT): Define unconditionally now.
7938 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
7939 (BITS_PER_EMACS_INT): New constants, replacing
7940 what used to be in config.h, but not useful in #if.
7941 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
7942 define them any more.
7943 (VAL_MAX): New macro.
7945 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
7946 BITS_PER_EMACS_INT, in #if.
7947 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
7948 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
7949 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
7950 * s/ms-w32.h (DATA_START):
7951 Move here from removed file m/intel386.h.
7952 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
7953 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
7955 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
7957 Assume C89 or later.
7958 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
7959 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
7961 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
7962 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
7963 * textprop.c, tparam.c (NULL): Remove.
7964 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
7965 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
7966 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
7967 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
7968 * xterm.c (input_signal_count): Assume volatile works.
7970 2012-05-21 Ken Brown <kbrown@cornell.edu>
7972 * xgselect.c (xg_select): Fix first argument in call to 'select'
7975 2012-05-20 Ken Brown <kbrown@cornell.edu>
7977 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
7978 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
7980 2012-05-19 Ken Brown <kbrown@cornell.edu>
7982 * xfns.c (x_in_use): Remove `static' qualifier.
7983 * xterm.h (x_in_use): Declare.
7984 * xgselect.c: Include xterm.h.
7985 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
7986 and `display_arg' (bug#9754).
7988 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
7990 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
7992 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
7993 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
7995 2012-05-18 Eli Zaretskii <eliz@gnu.org>
7997 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
7999 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
8000 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
8002 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
8003 reference to image_cache->refcount.
8004 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
8006 2012-05-17 Juri Linkov <juri@jurta.org>
8008 * search.c (Fword_search_regexp, Fword_search_backward)
8009 (Fword_search_forward, Fword_search_backward_lax)
8010 (Fword_search_forward_lax): Move functions to isearch.el
8011 (bug#10145, bug#11381).
8013 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
8015 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
8017 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
8019 * lread.c (init_obarray): Declare Qt and Qnil as special.
8021 2012-05-14 Glenn Morris <rgm@gnu.org>
8023 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
8024 Put "libexec" before "bin", for the sake of init_callproc_1.
8026 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
8028 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
8030 * unexaix.c: Port to more-recent AIX compilers.
8031 (report_error, report_error_1, make_hdr, copy_sym)
8032 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
8033 Make arguments const char *, not char *, to avoid violations of C
8034 standard and to fix some AIX warnings reported by Gilles Pion.
8036 2012-05-14 Eli Zaretskii <eliz@gnu.org>
8038 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
8039 already have overlays loaded.
8040 (handle_single_display_spec): Before returning without displaying
8041 fringe bitmap, synchronize the bidi iterator with the main display
8042 iterator, by calling iterate_out_of_display_property.
8043 (iterate_out_of_display_property): Detect buffer iteration by
8044 testing that it->string is a Lisp string.
8045 (get_next_display_element): When the current object is exhausted,
8046 and there's something on it->stack, call set_iterator_to_next to
8047 proceed with what's on the stack, instead of returning zero.
8048 (set_iterator_to_next): If called at the end of a Lisp string,
8049 proceed to consider_string_end without incrementing string
8050 position. Don't increment display vector index past the end of
8051 the display vector. (Bug#11417)
8052 (pos_visible_p): Don't report a position visible when move_it_to
8053 stopped at the last line of window, which happens to be scanned
8054 backwards by the bidi iteration. (Bug#11464)
8056 2012-05-14 Eli Zaretskii <eliz@gnu.org>
8058 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
8059 and right-margin display specs even if the spec is invalid or we
8060 are on a TTY, and thus unable to display on the fringes.
8061 That's because the text with the property will not be displayed anyway,
8062 so we need to signal to the caller that this is a "replacing"
8063 display spec. This fixes display when the spec is invalid or we
8066 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
8068 * unexaix.c (make_hdr): Fix typo in prototype.
8069 This bug broke the build on AIX. Problem reported by Gilles Pion.
8071 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
8073 * keyboard.c (kbd_buffer_get_event): Read special events also in
8074 batch mode. (Bug#11415)
8076 2012-05-12 Glenn Morris <rgm@gnu.org>
8078 * ns.mk: Update for ns_appbindir no longer having trailing "/".
8080 2012-05-12 Eli Zaretskii <eliz@gnu.org>
8082 * lisp.mk (lisp): Add newcomment.elc.
8084 2012-05-12 Glenn Morris <rgm@gnu.org>
8086 * Makefile.in (MKDIR_P): New, set by configure.
8087 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
8089 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
8091 Remove unused function hourglass_started.
8092 * dispextern.h (hourglass_started):
8093 * w32fns.c (hourglass_started):
8094 * xdisp.c (hourglass_started): Remove.
8096 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
8098 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
8099 Update dependencies.
8101 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
8103 * xgselect.c (xg_select): Put maxfds+1 into a var.
8104 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
8106 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
8108 2012-05-10 Dave Abrahams <dave@boostpro.com>
8110 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
8111 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
8113 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
8115 * dbusbind.c (xd_registered_buses): New internal Lisp object.
8116 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
8117 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
8118 Initialize xd_registered_buses.
8120 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
8122 Untag more efficiently if USE_LSB_TAG.
8123 This is based on a proposal by YAMAMOTO Mitsuharu in
8124 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
8125 For an admittedly artificial (nth 8000 longlist) benchmark on
8126 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
8127 Emacs's overall text size by 1%.
8128 * lisp.h (XUNTAG): New macro.
8129 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
8130 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
8131 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
8132 * eval.c (Fautoload):
8133 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
8134 * frame.h (XFRAME): Use XUNTAG.
8136 Port recent dbusbind.c changes to 32-bit --with-wide-int.
8137 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
8138 Remove unportable assumptions about print widths of types like
8140 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
8141 intptr_t when converting between pointer and integer, to avoid GCC
8142 warnings about wrong width.
8144 2012-05-09 Eli Zaretskii <eliz@gnu.org>
8146 * w32proc.c (new_child): Force Windows to reserve only 64KB of
8147 stack for each reader_thread, instead of defaulting to 8MB
8148 determined by the linker. This avoids failures in creating
8149 subprocesses on Windows 7, see the discussion in this thread:
8150 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
8152 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
8154 Fix up display of the *Minibuf-0* buffer in the mini window.
8155 * keyboard.c (read_char): Don't clear the echo area if there's no
8157 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
8158 contents of *Minibuf-0*) if there's no message displayed in its stead.
8160 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
8162 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
8165 2012-05-06 Chong Yidong <cyd@gnu.org>
8167 * lisp.mk (lisp): Update.
8169 2012-05-05 Jim Meyering <meyering@redhat.com>
8171 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
8173 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
8175 * data.c (PUT_ERROR): New macro.
8176 (syms_of_data): Use it. Add new error type `user-error'.
8177 * undo.c (user_error): New function.
8178 (Fprimitive_undo): Use it.
8179 * print.c (print_error_message): Adjust print style for `user-error'.
8180 * keyboard.c (user_error): New function.
8181 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
8183 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
8185 Do not limit current-time-string to years 1000..9999.
8186 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
8187 (Fcurrent_time_string): Support any year that is supported by the
8188 underlying localtime representation. Don't use asctime, as it
8189 has undefined behavior for years outside the range -999..9999.
8191 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
8193 Fix race conditions involving setenv, gmtime, localtime, asctime.
8194 Without this fix, interrupts could mess up code that uses these
8195 nonreentrant functions, since setting TZ invalidates existing
8196 tm_zone or tzname values, and since most of these functions return
8197 pointers to static storage.
8198 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
8199 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
8200 Grow the critical sections to include not just invoking
8201 localtime/gmtime, but also accessing these functions' results
8202 including their tm_zone values if any, and any related TZ setting.
8203 (format_time_string): Last arg is now struct tm *, not struct tm **,
8204 so that the struct tm is saved in the critical section.
8205 All callers changed. Simplify allocation of initial buffer, partly
8206 motivated by the fact that memory allocation needs to be outside
8207 the critical section.
8209 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
8211 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
8212 with RESET_INTERVAL.
8214 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
8215 Remove duplicated buffer name initialization.
8217 2012-05-02 Jim Meyering <jim@meyering.net>
8219 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
8221 * xfns.c (x_window): Use xstrdup (Bug#11375).
8223 2012-05-02 Eli Zaretskii <eliz@gnu.org>
8225 * xdisp.c (pos_visible_p): If already at a newline from the
8226 display string before the 'while' loop, don't walk back the glyphs
8227 from it3.glyph_row. Solves assertion violation when the display
8228 string begins with a newline (egg.el). (Bug#11367)
8230 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
8232 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
8235 2012-05-01 Glenn Morris <rgm@gnu.org>
8237 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
8238 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
8239 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
8240 All were removed before 23.1.
8242 * dispnew.c: Remove HAVE_LIBNCURSES test;
8243 it is always true on relevant platforms.
8245 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
8246 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
8248 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
8250 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
8252 * .gdbinit (xpr): Remove checks for no longer existing misc types.
8253 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
8256 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
8258 Do not avoid creating empty evaporating overlays (Bug#9642).
8259 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
8260 That is, do not delete an evaporating overlay if it becomes
8261 empty after its bounds are adjusted to fit within its buffer.
8262 This fix caused other problems, and I'm reverting it until we get
8263 to the bottom of them.
8265 2012-04-27 Chong Yidong <cyd@gnu.org>
8267 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
8269 2012-04-27 Eli Zaretskii <eliz@gnu.org>
8271 * xdisp.c (pos_visible_p): If the window start position is beyond
8272 ZV, start the display from buffer beginning. Prevents assertion
8273 violation in init_iterator when the minibuffer window is scrolled
8276 * window.c (window_scroll_pixel_based): Likewise.
8278 2012-04-27 Chong Yidong <cyd@gnu.org>
8280 * keymap.c (where_is_internal): Doc fix (Bug#10872).
8282 2012-04-27 Glenn Morris <rgm@gnu.org>
8284 * fileio.c (Fcopy_file, Fset_file_selinux_context):
8285 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
8287 2012-04-27 Eli Zaretskii <eliz@gnu.org>
8289 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
8290 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
8292 2012-04-26 Eli Zaretskii <eliz@gnu.org>
8294 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
8295 display element, check also the underlying string or buffer
8296 character. (Bug#11341)
8298 * w32menu.c: Include w32heap.h.
8299 (add_menu_item): If the call to AppendMenuW (via
8300 unicode_append_menu) fails, disable Unicode menus only if we are
8301 running on Windows 9X/Me.
8303 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
8305 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
8306 (xgetint): Add missing shift for LSB tags.
8308 2012-04-24 Martin Rudalics <rudalics@gmx.at>
8310 * keyboard.c (read_char): Don't wipe echo area for select window
8311 events: These might get delayed via `mouse-autoselect-window'
8314 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
8316 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
8317 manipulation of :loaded-from data.
8319 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
8321 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
8322 now a cons (bug#11311).
8324 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
8326 Do not create empty overlays with the evaporate property (Bug#9642).
8327 * buffer.c (Fmove_overlay): Delete an evaporating overlay
8328 if it becomes empty after its bounds are adjusted to fit within
8329 its buffer. Without this fix, in a nonempty buffer (let ((o
8330 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
8331 yields an empty overlay that has the evaporate property, which is
8332 not supposed to happen.
8334 Fix minor GTK3 problems found by static checking.
8335 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
8336 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
8337 (struct _EmacsFixedClass, emacs_fixed_get_type):
8338 Move decls here from emacsgtkfixed.h, since they needn't be public.
8339 (emacs_fixed_get_type): Now static.
8340 (emacs_fixed_class_init): Omit unused local.
8341 (emacs_fixed_child_type): Remove; unused.

8343 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
8344 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
8345 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
8346 (EMACS_FIXED_GET_CLASS): Remove; unused.
8347 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
8349 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
8350 Problem reported by Juanma Barranquero for Windows -Wunused-function.
8352 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
8354 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
8355 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
8356 (__malloc_size_t, __malloc_ptrdiff_t):
8357 Remove. All uses removed, replaced by the definiens if needed,
8358 since we can assume C89 or better now.
8359 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
8360 (protect_malloc_state, align, get_contiguous_space)
8361 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
8362 (malloc_atfork_handler_child, malloc_enable_thread)

8365 (_free, _realloc, _free_internal_nolock, _free_internal, free, cfree)
8366 (special_realloc, _realloc_internal_nolock, _realloc_internal)
8367 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
8368 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
8369 Define using prototypes, not old style.
8370 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
8371 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
8372 (align): Don't assume that signed integer overflow wraps around.
8373 Omit unused local var.
8374 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
8375 (_free_internal_nolock, memalign, mallochook, reallochook):
8376 Omit no-longer-needed casts.
8377 (valloc): Use getpagesize, not __getpagesize.
8378 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
8379 (struct hdr): The 'magic' member is now size_t, not unsigned long.
8381 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.

8436 since the two debugging options are incompatible.
8437 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
8439 (mem_init, mem_insert, mem_insert_fixup):
8440 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

8606 2012-04-11 Daniel Colascione <dancol@dancol.org>
8608 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
8609 against is gone. It's better to use vfork now so that when Cygwin
8610 gains a new, working vfork, we use it automatically (bug#10398).
8612 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

8667 2012-04-09 Eli Zaretskii <eliz@gnu.org>
8669 * xdisp.c (set_cursor_from_row): If the display string appears in
8670 the buffer at position that is closer to point than the position
8671 after the display string, display the cursor on the first glyph of
8672 the display string. Fixes cursor display when a 'display' text
8673 property immediately follows invisible text. (Bug#11094)
8675 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
8677 composite.c: use 'double' consistently
8678 * composite.c (get_composition_id): Use 'double' consistently
8679 instead of converting 'float' to 'double' and vice versa; this is

8729 [!WINDOWSNT]: New macros.
8730 (init_libxml2_functions, libxml2_loaded_p): New functions.
8731 (parse_region): Call fn_xmlCheckVersion instead of using the macro
8732 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
8733 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.

8754 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
8755 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
8756 about subtle differences between FETCH_CHAR* and STRING_CHAR*
8757 macros related to unification of CJK characters. For the details,
8758 see the discussion following the message here:
8759 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.

8778 position we get to after a call to move_it_to fails the
8779 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
8780 only if we wind up in a string from display property. (Bug#11063)
8782 * window.c (Fdelete_other_windows_internal): Invalidate the row
8783 and column information about mouse highlight, so that redisplay
8784 restores it after reallocating the glyph matrices. (Bug#7464)
8786 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
8787 string comes from a `display' text property, use the buffer
8788 position of that property as if we actually saw that position in
8790 (move_it_by_lines): Remove the assertion that
8791 "it->current_x == 0 && it->hpos == 0" which can be legitimately
8792 violated when there's a before-string at the beginning of a line.
8795 2012-03-30 Eli Zaretskii <eliz@gnu.org>

8852 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
8853 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
8854 when fetching a multibyte character consumes more bytes than
8855 CHAR_BYTES returns, due to unification of CJK characters in
8856 string_char. (Bug#11073)
8858 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
8860 * process.c (wait_reading_process_output): Handle pty disconnect
8861 by refraining from sending oneself a SIGCHLD (bug#10933).

8878 * w32proc.c (Fw32_set_console_codepage)
8879 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
8882 2012-03-20 Chong Yidong <cyd@gnu.org>
8884 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
8885 to reflect default non-nil value of redisplay-dont-pause.
8887 2012-03-19 Kenichi Handa <handa@m17n.org>
8889 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
8890 it fit in a valid range (Bug#11003).
8892 2012-03-18 Eli Zaretskii <eliz@gnu.org>
8894 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
8895 that is not from display property, accept the row as a "cursor
8896 row" if one of the string's character has a non-nil `cursor'
8897 property. Fixes cursor positioning when there are newlines in
8898 overlay strings, e.g. in icomplete.el. (Bug#11035)
8900 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
8902 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
8904 2012-03-12 Chong Yidong <cyd@gnu.org>
8906 * eval.c (inhibit_lisp_code): Rename from
8907 inhibit_window_configuration_change_hook; move from window.c.
8909 * xfns.c (unwind_create_frame_1, Fx_create_frame):
8910 * window.c (run_window_configuration_change_hook)
8911 (syms_of_window): Callers changed.

8931 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
8934 2012-03-03 Glenn Morris <rgm@gnu.org>
8936 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
8938 2012-03-02 Eli Zaretskii <eliz@gnu.org>
8940 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
8941 position past the first glyph_row that ends at ZV. (Bug#10902)
8942 (redisplay_window, next_element_from_string): Fix typos in
8944 (redisplay_window): Pass to move_it_vertically the margin in
8945 pixels, not in screen lines.
8947 2012-03-02 Glenn Morris <rgm@gnu.org>
8949 * buffer.c (buffer-list-update-hook): Doc fix.
8951 2012-02-29 Eli Zaretskii <eliz@gnu.org>

8954 push_it before setting up the iterator for the first overlay
8955 string, even if we have an empty string loaded.
8956 (next_overlay_string): If there's an empty string on the iterator
8957 stack, pop the stack. (Bug#10903)
8959 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
8961 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
8962 Suggested by Stefan Monnier in
8963 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
8964 * alloc.c (widen_to_Lisp_Object): New static function.
8965 (mark_memory): Also mark Lisp_Objects by fetching pointer words
8966 and widening them to Lisp_Objects. This would work even if
8967 USE_LSB_TAG is defined and wide integers are used, which might
8968 happen in a future version of Emacs.
8970 2012-02-25 Chong Yidong <cyd@gnu.org>
8972 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
8975 * xselect.c (Fx_selection_exists_p): Doc fix.
8976 (x_clipboard_manager_save_all): Print an informative message
8977 before saving to clipboard manager.
8979 2012-02-24 Chong Yidong <cyd@gnu.org>
8981 * keyboard.c (process_special_events): Handle all X selection
8982 requests in kbd_buffer, not just the next one (Bug#8869).
8984 2012-02-23 Chong Yidong <cyd@gnu.org>
8986 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
8987 call when setting menu-bar-lines and tool-bar-lines parameters.
8988 (unwind_create_frame_1): New helper function.
8990 * window.c (inhibit_window_configuration_change_hook): New var.
8991 (run_window_configuration_change_hook): Obey it.
8992 (syms_of_window): Initialize it.
8994 2012-02-22 Chong Yidong <cyd@gnu.org>
8996 * xterm.c (x_draw_image_relief): Add missing type check for
8997 Vtool_bar_button_margin (Bug#10743).

9001 * fileio.c (Vfile_name_handler_alist): Doc fix.
9003 * buffer.c (Fget_file_buffer): Protect against invalid file
9004 handler return value.
9006 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
9008 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
9009 when computing $valmask.
9011 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
9012 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
9013 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
9014 It's useless in that case, and it can cause problems on hosts
9015 that allocate halves of EMACS_INT values separately.
9016 Reported by Dan Horák. Diagnosed by Andreas Schwab in
9017 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
9018 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
9019 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
9020 it avoids undefined behavior on hosts where shifting right by more
9021 than the word width has undefined behavior.
9023 2012-02-19 Chong Yidong <cyd@gnu.org>
9025 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
9026 (Funhandled_file_name_directory, Ffile_name_as_directory)
9027 (Fdirectory_file_name, Fexpand_file_name)

9045 2012-02-15 Chong Yidong <cyd@gnu.org>
9047 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
9048 marked as special. Also, starting docstrings with * is obsolete.
9050 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
9052 * gnutls.c (emacs_gnutls_write): Fix last change.
9054 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

9063 2012-02-12 Chong Yidong <cyd@gnu.org>
9065 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
9066 as that creates a dangerous corner case.
9068 * window.c (Fdelete_window_internal): Invalidate the mouse
9069 highlight (Bug#9904).
9071 2012-02-12 Glenn Morris <rgm@gnu.org>

9076 * nsselect.m (Fx_own_selection_internal)
9077 (Fx_disown_selection_internal, Fx_selection_exists_p)
9078 (Fx_selection_owner_p, Fx_get_selection_internal):
9079 Sync docs and argument specs with the xselect.c versions.
9081 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
9083 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

9097 2012-02-09 Kenichi Handa <handa@m17n.org>
9099 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
9101 2012-02-07 Chong Yidong <cyd@gnu.org>
9103 * buffer.c (Fbuffer_local_variables)
9104 (buffer_lisp_local_variables): Handle unbound vars correctly;
9105 don't let Qunbound leak into Lisp.
9107 2012-02-07 Glenn Morris <rgm@gnu.org>
9109 * image.c (Fimagemagick_types): Doc fix.
9111 * image.c (imagemagick-render-type): Change it from a lisp object
9112 to an integer. Move the doc here from the lisp manual.

9117 * doc.c (store_function_docstring): Avoid applying docstring of
9118 alias to base function (Bug#2603).
9120 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
9122 * .gdbinit (pp1, pv1): Remove redundant defines.
9125 2012-02-04 Chong Yidong <cyd@gnu.org>

9144 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
9146 Handle overflow when computing char display width (Bug#9496).
9147 * character.c (char_width): Return EMACS_INT, not int.
9148 (char_width, c_string_width): Check for overflow when
9149 computing the width; this is possible now that individual
9150 characters can have unbounded width. Problem introduced
9151 by merge from Emacs 23 on 2012-01-19.
9153 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
9155 * dbusbind.c (Fdbus_register_method): Mention the return value

9168 2012-02-02 Kenichi Handa <handa@m17n.org>
9170 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
9171 0, do not call append_composite_glyph.

9182 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
9183 first 2 arguments are identical. This makes inserting large
9184 output from a subprocess an order of magnitude faster on
9185 MS-Windows, where all sbrk'ed memory is always contiguous.

9243 * character.c (char_width): New function.
9244 (Fchar_width, c_string_width, lisp_string_width):

9270 2012-01-11 Glenn Morris <rgm@gnu.org>
9272 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
9273 from load-path also when installation-directory is nil. (Bug#10208)
9275 2012-01-10 Glenn Morris <rgm@gnu.org>
9277 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.

9284 * xdisp.c (rows_from_pos_range): Accept additional argument
9285 DISP_STRING, and accept any glyph in a row whose object is that
9286 string as eligible for mouse highlight. Fixes mouse highlight of
9287 display strings from overlays. (Bug#10464)
9289 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
9291 emacs: fix an auto-save permissions race condition (Bug#10400)
9292 * fileio.c (auto_saving_dir_umask): New static var.
9293 (Fmake_directory_internal): Use it.
9294 (do_auto_save_make_dir): Set it, instead of invoking chmod after
9295 creating the directory. The old code temporarily assigns
9296 too-generous permissions to the directory.
9297 (do_auto_save_eh): Clear it.
9298 (Fdo_auto_save): Catch all errors, not just file errors, so
9299 that the var is always cleared.

9303 * search.c (scan_buffer): Pass character positions to
9304 know_region_cache, not byte positions. (Bug#6540)

9345 * xmenu.c (x_menu_wait_for_event): Use xg_select for Gtk3 so menus

9352 * callint.c (Fcall_interactively): Don't truncate prompt string.
9354 2011-12-23 Eli Zaretskii <eliz@gnu.org>
9356 * xdisp.c (handle_invisible_prop): Handle correctly an invisible
9357 property that ends at ZV, so that the bidi iteration could be

9805 is set, removing the need for VIRT_ADDRESS_VARIES.
9806 (PURE_P): Use a more-efficient implementation that needs just one

9821 (erase_phys_cursor, update_window_cursor, show_mouse_face)
9822 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
9823 behave as if the cursor position were at the window margin.
9825 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
9826 and the cursor position is out of bounds, behave as if the cursor
9827 position were at the window margin. (Bug#10075)
9829 2011-11-18 Chong Yidong <cyd@gnu.org>
9831 * window.c (Fwindow_combination_limit): Make first argument

10303 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
10304 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
10305 (Fmove_to_window_line): Doc fix.
10307 2011-10-27 Chong Yidong <cyd@gnu.org>
10309 * process.c (make_process): Set gnutls_state to NULL.
10311 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
10312 non-NULL, regardless of GNUTLS_INITSTAGE.
10313 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
10314 an error. Set process slots as soon as we allocate them.
10316 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
10318 2011-10-27 Chong Yidong <cyd@gnu.org>
10320 * gnutls.c (emacs_gnutls_deinit): New function.
10321 Deallocate credentials structures as well as calling gnutls_deinit.
10322 (Fgnutls_deinit, Fgnutls_boot): Use it.
10324 * process.c (make_process): Initialize GnuTLS credentials to NULL.
10325 (deactivate_process): Call emacs_gnutls_deinit.
10327 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
10329 * image.c (x_create_x_image_and_pixmap):

10334 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
10336 * w32fns.c (w32_default_color_map): New function,
10337 extracted from Fw32_default_color_map.
10338 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
10340 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
10342 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
10344 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
10346 * keyboard.c (test_undefined): New function (bug#9751).
10347 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
10349 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
10351 * sysdep.c (init_sys_modes): Fix the check for the controlling
10352 terminal (Bug#6649).
10354 2011-10-20 Eli Zaretskii <eliz@gnu.org>
10356 * dispextern.h (struct bidi_it): New member next_en_type.
10358 * bidi.c (bidi_line_init): Initialize the next_en_type member.
10359 (bidi_resolve_explicit_1): When next_en_pos is valid for the
10360 current character, check also for next_en_type being WEAK_EN.
10361 (bidi_resolve_weak): Don't enter the expensive loop if the current
10362 position is before next_en_pos. Record the bidi type of the first
10363 non-ET, non-BN character we find, in addition to its position.
10364 (bidi_level_of_next_char): Invalidate next_en_type when
10365 next_en_pos is over-stepped.
10367 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
10369 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
10370 * editfns.c: Rewrite current-time-zone so that it invokes
10371 the equivalent of (format-time-string "%Z") to get the time zone name.
10372 This fixes a bug when the time zone name contains characters that
10373 need converting from the system time locale to Emacs internal format.
10374 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
10375 that patch fixed format-time-string to do the conversion, but
10376 I forgot to fix current-time-zone.
10377 (format_time_string): New function, containing most of
10378 what Fformat_time_string used to contain.
10379 (Fformat_time_string): Rewrite in terms of format_time_string.
10380 This doesn't change this function's behavior.
10381 (current-time-zone): Rewrite to use format_time_string.
10382 This fixes the bug reported by Michael Schierl in
10383 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
10384 Jason Rumney's 2007-06-07 change worked around this bug, but
10386 * systime.h (tzname, timezone): Remove no-longer-used declarations.
10388 2011-10-19 Eli Zaretskii <eliz@gnu.org>
10390 * xdisp.c (start_display): If the character at POS is displayed
10391 via a display vector, reset IT->current.dpvec_index to zero.
10392 (try_window_reusing_current_matrix): If a line ends in a display
10393 vector or the next line starts in a display vector, continue
10394 redrawing the window even though the character position of
10395 start_row was reached.
10398 2011-10-18 Chong Yidong <cyd@gnu.org>
10400 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
10401 with nobreak-char-display too.
10403 2011-10-18 Eli Zaretskii <eliz@gnu.org>
10405 Fix part 3 of bug#9771.
10406 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
10407 (bidi_resolve_neutral): Don't enter the expensive loop looking for
10408 non-neutral characters if the current character is a paragraph
10409 separator (a.k.a. Newline). This avoids running the same
10410 expensive loop twice, once when we consume the preceding newline
10411 and the other time when the line actually needs to be displayed.
10412 Avoid the loop when we see neutrals on the base embedding level
10413 following a character whose directionality is the same as the
10414 paragraph's. This avoids running the expensive loop when a line
10415 ends in a long sequence of neutrals, like control characters.
10416 Add assertion against STRONG_AL type. Slightly rearrange code
10417 that determines the type of a neutral given the first non-neutral
10419 (bidi_level_of_next_char): Set next_en_pos to zero when
10420 invalidating its info.
10422 2011-10-17 Eli Zaretskii <eliz@gnu.org>
10424 * xdisp.c (push_display_prop): Determine whether to record string
10425 or buffer position by IT->string, not by IT->method. Allow
10426 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
10427 (move_it_vertically_backward): Don't look for character position
10428 immediately after the newline when in a continuation line.
10431 2011-10-15 Martin Rudalics <rudalics@gmx.at>
10433 * window.c (coordinates_in_window): Rewrite and delabelize
10434 vertical border check. (Bug#5357) (Bug#9618)
10436 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
10438 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
10439 errors in XSetWindowBorder (bug#9310).
10441 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
10443 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
10444 avoid crash when xmalloc overrun checking is enabled.
10446 2011-10-13 Eli Zaretskii <eliz@gnu.org>
10448 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
10449 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
10450 cursor motion with <left> and <right> arrow keys.
10452 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
10453 some callers set that themselves.
10455 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10457 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
10458 display string and the previous row comes from the same string and
10459 is empty. (Bug#9739) (Bug#9738)
10461 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
10463 * doc.c (get_doc_string): Encode file name (bug#9735).
10465 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10467 * bidi.c (bidi_level_of_next_char):
10468 * xdisp.c (get_visually_first_element): Remove old incorrect
10469 comments regarding the Unicode Line Separator character.
10471 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
10473 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
10475 * alloc.c (Fgc_status): Do not access beyond zombies array
10476 boundary if nzombies > MAX_ZOMBIES.
10477 * alloc.c (dump_zombies): Add missing format specifier.
10479 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
10481 * xdisp.c (set_cursor_from_row): Simplify conditionals,
10482 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
10484 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
10485 Some packages use them to denote characters with modifiers.
10487 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
10489 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
10490 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
10491 matching a pp-number. Rename parameter var to var1.
10493 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
10495 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
10497 2011-10-08 Glenn Morris <rgm@gnu.org>
10499 * callint.c (Fcall_interactively): Give a more explicit error for the
10500 'c' case with a non-character input. (Bug#8479)
10502 2011-10-08 Eli Zaretskii <eliz@gnu.org>
10504 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
10506 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
10507 lines that are hscrolled on the left.
10509 * dispnew.c (buffer_posn_from_coords): Account for a possible
10510 presence of header-line. (Bug#4426)
10512 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
10514 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
10515 Don't advertise functionality which we discourage or doesn't work.
10517 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
10519 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
10520 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
10521 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
10522 this makes Emacs dump core during garbage collection on rare
10523 occasions. sizeof is obviously inferior to offsetof here, so
10524 stick with offsetof.
10525 (GC_POINTER_ALIGNMENT): New macro.
10526 (mark_memory): Omit 3rd (offset) arg; caller changed.
10527 Don't assume EMACS_INT alignment is the same as pointer alignment.
10529 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
10531 * keyboard.c (read_key_sequence_remapped): New var.
10532 (read_key_sequence): Compute remapping in the right buffer.
10533 (command_loop_1): Use read_key_sequence's remapping directly.
10535 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
10537 * dired.c (file_name_completion): Don't expand file name.
10538 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
10539 before checking file name handler.
10541 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
10542 they've been requested explicitly (bug#9591).
10544 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
10546 * keymap.c (Fsingle_key_description): Use make_specified_string
10547 instead of build_string to build string from push_key_description.
10550 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10552 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
10553 This fixes a Y2038 bug on 64-bit hosts.
10554 * buffer.c (reset_buffer):
10555 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
10556 (Fclear_buffer_auto_save_failure):
10557 Use 0, not -1, to represent an unset failure time, since time_t
10558 might not be signed.
10560 Remove dependency on glibc malloc internals.
10561 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10562 Move back here from lisp.h, but with their new implementations.
10563 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10564 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
10565 * charset.c (charset_table_init): New static var.
10566 (syms_of_charset): Use it instead of xmalloc. This removes a
10567 dependency on glibc malloc internals. See Eli Zaretskii's comment in
10568 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
10569 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10570 Move back to alloc.c.
10571 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10572 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
10574 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
10576 * nsterm.m (windowDidResize): Call x_set_window_size only when
10577 ns_in_resize is true. Otherwise set pixelwidth/height and
10578 call change_frame_size (Bug#9628).
10580 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10582 Port --enable-checking=all to Fedora 14 x86-64.
10583 * charset.c (syms_of_charset): Also account for glibc malloc's
10584 internal overhead when calculating the initial malloc maximum.
10586 Port --enable-checking=all to Fedora 14 x86.
10587 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10589 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
10590 (overrun_check_realloc, overrun_check_free):
10591 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
10592 That way, xmalloc returns a properly-aligned pointer even if
10593 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
10594 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
10595 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
10596 into account when calculating the initial malloc maximum.
10597 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10598 Move here from alloc.c, so that charset.c can use it too.
10599 Properly align; the old code wasn't right for common 32-bit hosts
10600 when configured with --enable-checking=all.
10601 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10602 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
10604 2011-09-29 Eli Zaretskii <eliz@gnu.org>
10606 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
10609 2011-09-28 Eli Zaretskii <eliz@gnu.org>
10611 * xdisp.c (compute_display_string_end): If there's no display
10612 string at CHARPOS, return -1.
10614 * bidi.c (bidi_fetch_char): When compute_display_string_end
10615 returns a negative value, treat the character as a normal
10616 character not covered by a display string. (Bug#9624)
10618 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
10620 * lread.c (Fread_from_string): Fix typo in docstring.
10622 2011-09-27 Eli Zaretskii <eliz@gnu.org>
10624 * xdisp.c (handle_invisible_prop): If invisible text ends on a
10625 newline, reseat the iterator instead of bidi-iterating there one
10626 character at a time. (Bug#9610)
10627 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
10628 TO_CHARPOS if the bidi iterator is at base embedding level.
10630 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
10632 * lread.c (readevalloop): Use correct code for NBSP.
10633 (read1): Likewise. (Bug#9608)
10635 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
10637 * dbusbind.c (Fdbus_register_signal): When service is not
10638 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
10640 2011-09-25 Glenn Morris <rgm@gnu.org>
10642 * buffer.c (truncate-lines): Doc fix.
10644 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
10646 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
10647 (Fset_window_next_buffers): Doc fix.
10649 2011-09-24 Glenn Morris <rgm@gnu.org>
10651 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
10653 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
10655 Fix minor problems found by static checking.
10656 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
10657 * indent.c (Fvertical_motion): Fix == vs = typo.
10659 2011-09-24 Eli Zaretskii <eliz@gnu.org>
10661 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
10662 Default value is now t. Doc fix.
10664 * indent.c (Fvertical_motion): Compute and apply the overshoot
10665 logic when moving up, not only when moving down. Fix the
10666 confusing name and values of the it_overshoot_expected variable;
10667 logic changes accordingly. (Bug#9254) (Bug#9549)
10669 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
10670 CHARPOS is covered by a display string which includes newlines.
10671 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
10672 is covered by a display string with embedded newlines.
10674 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
10676 * dbusbind.c (Fdbus_register_signal): Add match rule to
10677 Vdbus_registered_objects_table. (Bug#9581)
10678 (Fdbus_register_method, Vdbus_registered_objects_table):
10681 2011-09-24 Jim Meyering <meyering@redhat.com>
10683 do not ignore write error for any output size
10684 The previous change was incomplete.
10685 While it makes emacs --batch detect the vast majority of stdout
10686 write failures, errors were still ignored whenever the output size is
10687 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
10688 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
10689 && echo FAIL: ignored write error
10690 FAIL: ignored write error
10691 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
10692 && echo FAIL: ignored write error
10693 FAIL: ignored write error
10694 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
10696 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
10698 * emacs.c (Fkill_emacs): In noninteractive mode exit
10699 non-successfully if a write error occurred on stdout. (Bug#9574)
10701 2011-09-21 Eli Zaretskii <eliz@gnu.org>
10703 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
10706 * dispextern.h (struct it): Update the comment documenting what
10709 2011-09-20 Eli Zaretskii <eliz@gnu.org>
10711 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
10712 a display string, extend search for cursor position to end of row.
10713 (find_row_edges): If the row ends in a newline from a display
10714 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
10715 Handle the case of a display string with multiple newlines.
10716 (Fcurrent_bidi_paragraph_direction): Fix search for previous
10717 non-empty line. Fixes confusing cursor motion with arrow keys at
10718 the beginning of a line that starts with whitespace.
10720 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
10722 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
10725 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
10727 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
10728 boolean (Bug#9154).
10730 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10732 * xdisp.c (display_line): Record maximum and minimum buffer
10733 positions even if no glyphs were produced (e.g., by a zero-width
10734 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
10735 buffer positions that will be removed from the glyph row because
10737 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
10738 column is beyond frame width: don't subtract 1 "pixel" when
10739 computing width of the stretch.
10740 (reseat_at_next_visible_line_start): Undo the change made on
10741 2011-09-17 that saved paragraph information and restored it after
10742 the call to `reseat'. (Bug#9545)
10744 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10746 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
10747 and turn window cursor on if cleared (Bug#9415).
10749 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
10751 * search.c (boyer_moore): Take unibyte characters from pattern
10752 literally. (Bug#9458)
10754 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10756 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
10758 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
10760 Fix minor problem found by static checking.
10761 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
10762 initialized, to pacify gcc -Wuninitialized.
10764 * fileio.c: Report proper errno when syscall falls.
10765 (Finsert_file_contents): Save and restore errno,
10766 so that report_file_error outputs the correct diagnostic.
10767 (Fwrite_region) [CLASH_DETECTION]: Likewise.
10769 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10771 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
10773 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10775 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
10776 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
10778 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10780 * xdisp.c (reseat_at_next_visible_line_start): Keep information
10781 about the current paragraph and restore it after the call to reseat.
10783 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
10784 (bidi_find_paragraph_start): Search back for paragraph beginning
10785 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
10786 (bidi_move_to_visually_next): Only trigger paragraph-related
10787 computations when the last character is a newline or at EOB, not
10788 just any NEUTRAL_B. (Bug#9470)
10790 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
10791 truncated lines if point is covered by a display string. (Bug#9524)
10793 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
10795 * xselect.c: Relax test for outgoing X longs (Bug#9498).
10796 (cons_to_x_long): New function.
10797 (lisp_data_to_selection_data): Use it. Correct the test for
10798 short-versus-long data; it was negated. Break out of vector
10799 loop, for efficiency, when a long datum is discovered.
10801 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
10803 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
10805 2011-09-16 Eli Zaretskii <eliz@gnu.org>
10807 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
10808 GCC PR/17406) by declaring this function with external scope.
10810 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10812 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
10813 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
10815 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
10817 * editfns.c (Fformat): Correctly handle text properties on "%%".
10819 2011-09-15 Eli Zaretskii <eliz@gnu.org>
10821 * xterm.c (x_draw_composite_glyph_string_foreground):
10822 * w32term.c (x_draw_composite_glyph_string_foreground):
10823 * term.c (encode_terminal_code):
10824 * composite.c (composition_update_it, get_composition_id):
10825 * xdisp.c (get_next_display_element)
10826 (fill_composite_glyph_string): Add comments about special meaning
10827 of TAB characters in a composition.
10829 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10831 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
10832 This occurs when processing a multibyte format.
10833 Problem reported by Wolfgang Jenker.
10835 2011-09-15 Johan Bockgård <bojohan@gnu.org>
10837 * xdisp.c (try_cursor_movement): Only check for exact match if
10838 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
10840 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10842 Remove unused external symbols.
10843 * dispextern.h (calc_pixel_width_or_height): Remove decl.
10844 * xdisp.c (calc_pixel_width_or_height): Now static.
10845 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
10846 * indent.c (check_display_width):
10847 * w32term.c: Fix comment to match code.
10848 * xterm.c, xterm.h (x_catching_errors): Remove.
10850 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10852 * xselect.c: Use signed conversions more consistently (Bug#9498).
10853 (selection_data_to_lisp_data): Assume incoming selection data are
10854 signed integers, not unsigned. This is to be consistent with
10855 outgoing selection data, which was modified to use signed integers
10856 in as part of the fix to Bug#9196 in response to Jan D.'s comment
10857 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
10858 expects long, not unsigned long.
10860 2011-09-14 Eli Zaretskii <eliz@gnu.org>
10862 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
10863 computation of loop end. Reported by Johan Bockgård
10866 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
10868 * frame.c (Fother_visible_frames_p): Function deleted.
10870 2011-09-12 Eli Zaretskii <eliz@gnu.org>
10872 * indent.c (compute_motion): Process display vector front to back
10873 rather than the other way around. (Bug#2496)
10875 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
10877 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
10879 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
10881 * minibuf.c (Fread_from_minibuffer): Doc fix.
10883 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10885 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
10886 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
10888 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
10890 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
10891 value for non-existent files.
10893 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10895 * fileio.c (Finsert_file_contents): If the file cannot be opened,
10896 set its "size" to -1. This will set the modtime_size field of
10897 the corresponding buffer to -1, which is what
10898 verify-visited-file-modtime expects for files that do not exist.
10901 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
10903 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
10905 * lisp.h: ... from here. push_key_description is no longer
10906 defined in keyboard.c, so its declaration should not be in
10907 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
10908 logically belongs with push_key_description.
10910 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
10912 * buffer.h: Include <sys/types.h> instead of <time.h>.
10913 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
10914 Problem reported by Herbert J. Skuhra.
10916 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
10918 * xml.c (parse_region): Make the parsing work for
10919 non-comment-starting XML files again (bug#9144).
10921 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
10923 * image.c (gif_load): Fix calculation of bottom and right corner.
10926 2011-09-10 Eli Zaretskii <eliz@gnu.org>
10928 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
10929 redisplay in small windows.
10931 2011-09-09 Eli Zaretskii <eliz@gnu.org>
10933 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
10935 2011-09-08 Martin Rudalics <rudalics@gmx.at>
10937 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
10938 Operate on live windows only.
10940 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
10942 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
10944 2011-09-07 Eli Zaretskii <eliz@gnu.org>
10946 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
10947 only under bidi iteration.
10949 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
10951 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
10953 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10955 isnan: Fix porting problem to Solaris 10 with bundled gcc.
10956 Without this fix, the command to link temacs failed due to an
10957 undefined symbol __builtin_isnan. This is because
10958 /usr/include/iso/math_c99.h #defines isnan(x) to
10959 __builtin_isnan(x), but the bundled gcc, which identifies itself
10960 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
10962 * floatfns.c (isnan): #undef, and then #define to a clone of
10964 (Fisnan): Always define, since it's always available now.
10965 (syms_of_floatfns): Always define isnan at the Lisp level.
10967 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10969 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
10971 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10973 * fileio.c: Fix bugs with large file offsets (Bug#9428).
10974 The previous code assumed that file offsets (off_t values) fit in
10975 EMACS_INT variables, which is not true on typical 32-bit hosts.
10976 The code messed up by falsely reporting buffer overflow in cases
10977 such as (insert-file-contents "big" nil 1 2) into an empty buffer
10978 when "big" contains more than 2**29 bytes, even though this
10979 inserts just one byte and does not overflow the buffer.
10980 (Finsert_file_contents): Store file offsets as off_t
10981 values, not as EMACS_INT values. Check for overflow when
10982 converting between EMACS_INT and off_t. When checking for
10983 buffer overflow or for overlap, take the offsets into account.
10984 Don't use EMACS_INT for small values where int suffices.
10985 When checking for overlap, fix a typo: ZV was used where
10986 ZV_BYTE was intended.
10987 (Fwrite_region): Don't assume off_t fits into 'long'.
10988 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
10990 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
10992 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
10994 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10996 sprintf-related integer and memory overflow issues (Bug#9412).
10998 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
10999 (esprintf, exprintf, evxprintf): New functions.
11000 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
11001 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
11002 (modify_event_symbol): Do not assume that the length of
11003 name_alist_or_stem is safe to alloca and fits in int.
11004 (Fexecute_extended_command): Likewise for function name and binding.
11005 (Frecursion_depth): Wrap around reliably on integer overflow.
11006 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
11007 since some callers pass EMACS_INT values.
11008 (Fsingle_key_description): Don't crash if symbol name contains more
11009 than MAX_ALLOCA bytes.
11010 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
11011 (get_minibuffer): Arg is now EMACS_INT, not int.
11012 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
11013 (esprintf, exprintf, evxprintf): New decls.
11014 * window.h (command_loop_level, minibuf_level): Reflect API changes.
11016 * dbusbind.c (signature_cat): New function.
11017 (xd_signature, Fdbus_register_signal):
11018 Do not overrun buffer; instead, report string overflow.
11020 * dispnew.c (add_window_display_history): Don't overrun buffer.
11021 Truncate instead; this is OK since it's just a log.
11023 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
11024 even if the time zone offset is outlandishly large.
11025 Don't mishandle offset == INT_MIN.
11027 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
11028 when creating daemon; the previous buffer-overflow check was incorrect.
11030 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
11031 which has the guts of the old verror function.
11033 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
11034 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
11036 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
11037 (font_unparse_xlfd): Don't blindly alloca long strings.
11038 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
11039 fits in int, when using sprintf. Use single snprintf to count
11040 length of string rather than counting it via multiple sprintfs;
11041 that's simpler and more reliable.
11042 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
11043 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
11044 sprintf, in case result does not fit in int.
11046 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
11047 (fontset_from_font): Print it.
11049 * frame.c (tty_frame_count): Now printmax_t, not int.
11050 (make_terminal_frame, set_term_frame_name): Print it.
11051 (x_report_frame_params): In X, window IDs are unsigned long,
11052 not signed long, so print them as unsigned.
11053 (validate_x_resource_name): Check for implausibly long names,
11054 and don't assume name length fits in 'int'.
11055 (x_get_resource_string): Don't blindly alloca invocation name;
11056 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
11059 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
11060 (xg_check_special_colors, xg_set_geometry):
11061 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
11063 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
11064 Use esprintf, not sprintf, in case result does not fit in int.
11066 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11067 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
11068 it as a large positive number.
11069 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
11070 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11072 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
11073 in case result does not fit in int.
11075 * print.c (float_to_string): Detect width overflow more reliably.
11076 (print_object): Make sprintf buffer a bit bigger, to avoid potential
11077 buffer overrun. Don't assume list length fits in 'int'. Treat
11078 print length of 0 as 0, not as infinity; to be consistent with other
11079 uses of print length in this function. Don't overflow print length
11080 index. Don't assume hash table size fits in 'long', or that
11081 vectorlike size fits in 'unsigned long'.
11083 * process.c (make_process): Use printmax_t, not int, to format
11084 process-name gensyms.
11086 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
11088 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
11089 to avoid potential buffer overrun.
11091 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
11092 if X resource line is longer than 512 bytes.
11094 * xfns.c (x_window): Make sprintf buffer a bit bigger
11095 to avoid potential buffer overrun.
11097 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
11099 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
11101 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
11103 Integer overflow fixes for scrolling, etc.
11104 Without these, Emacs silently mishandles large integers sometimes.
11105 For example, "C-u 4294967297 M-x recenter" was treated as if
11106 it were "C-u 1 M-x recenter" on a typical 64-bit host.
11108 * xdisp.c (try_window_id): Check Emacs fixnum range before
11109 converting to 'int'.
11111 * window.c (window_scroll_line_based, Frecenter):
11112 Check that an Emacs fixnum is in range before assigning it to 'int'.
11113 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
11114 values converted from Emacs fixnums.
11115 (Frecenter): Don't wrap around a line count if it is out of 'int'
11116 range; instead, treat it as an extreme value.
11117 (Fset_window_configuration, compare_window_configurations):
11118 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
11120 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
11121 that can exceed INT_MAX. Check that EMACS_INT value is in range
11122 before assigning it to the (possibly-narrower) index.
11123 (match_limit): Don't assume that a fixnum can fit in 'int'.
11125 * print.c (print_object): Use ptrdiff_t, not int, for index that can
11128 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
11129 (Fvertical_motion): Don't wrap around LINES values that don't fit
11130 in 'int'. Instead, treat them as extreme values. This is good
11131 enough for windows, which can't have more than INT_MAX lines anyway.
11133 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
11135 * Require libxml/parser.h to avoid compilation warning.
11137 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
11139 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
11140 since this reportedly can destroy thread storage.
11142 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
11144 * syntax.c (find_defun_start): Update all cache variables if
11145 exiting early (Bug#9401).
11147 2011-08-30 Eli Zaretskii <eliz@gnu.org>
11149 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
11151 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
11152 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
11153 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
11155 * term.c (tty_append_glyph): New function.
11156 (produce_stretch_glyph): Static function and its prototype deleted.
11158 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
11161 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
11163 * image.c (parse_image_spec): Check for nonnegative, not for positive,
11164 when checking :margin (Bug#9390).
11165 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
11166 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
11167 so that the name doesn't mislead. All uses changed.
11169 2011-08-28 Johan Bockgård <bojohan@gnu.org>
11171 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
11174 2011-08-27 Eli Zaretskii <eliz@gnu.org>
11176 * xdisp.c (move_it_to): Don't bail out early when reaching
11177 position beyond to_charpos, if we are scanning backwards.
11178 (move_it_vertically_backward): When DY == 0, make sure we get to
11179 the first character in the line after the newline.
11181 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
11183 * ccl.c: Improve and simplify overflow checking (Bug#9196).
11184 (ccl_driver): Do not generate an out-of-range pointer.
11185 (Fccl_execute_on_string): Remove unnecessary check for
11186 integer overflow, noted by Stefan Monnier in
11187 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
11188 Remove a FIXME that didn't need fixing.
11189 Simplify the newly-introduced buffer reallocation code.
11191 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
11193 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
11195 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
11197 Integer and memory overflow issues (Bug#9196).
11199 * doc.c (get_doc_string): Rework so that
11200 get_doc_string_buffer_size is the actual buffer size, rather than
11201 being 1 less than the actual buffer size; this makes xpalloc more
11204 * image.c (x_allocate_bitmap_record, cache_image):
11205 * xselect.c (Fx_register_dnd_atom):
11206 Simplify previous changes by using xpalloc.
11208 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
11209 since either will do and ptrdiff_t is convenient with xpalloc.

11213 (charset_compare): Don't overflow if priorities differ greatly.

11219 * cmds.c (internal_self_insert): Check for size-calculation overflow.
11221 * composite.h (struct composition.glyph_len): Now int, not unsigned.
11222 The actual value is always <= INT_MAX, and leaving it unsigned made

11226 (struct face_cache.size): Now ptrdiff_t, for convenience in use
11227 with xpalloc. The values are still always <= INT_MAX.

11237 (revalidate_region_cache, know_region_cache, region_cache_forward)
11238 (region_cache_backward, pp_cache):
11239 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
11240 so that ptrdiff_t * can be passed to xpalloc.
11241 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
11242 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.

11257 * buffer.c (overlays_at, overlays_in, record_overlay_string)
11259 Don't update size of array until after memory allocation succeeds,
11260 because xmalloc/xrealloc may not return.
11261 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
11262 now that we have proper integer overflow checking.
11263 (record_overlay_string, overlay_strings): Catch overflows when
11264 calculating size of overlay_str_buf.
11266 * callproc.c (Fcall_process): Check for size overflow when
11267 calculating size of args2.
11268 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
11269 Normally we prefer signed values, but sticking with ptrdiff_t would
11270 require adding more-complicated checks.
11272 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
11273 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
11274 Redo buffer-overflow calculations to avoid integer overflow.
11275 Add a FIXME comment where memory seems to be over-allocated.
11277 * character.c (Fstring): Check for size-calculation overflow.
11279 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid

11313 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
11315 * emacs.c (main): Do not reallocate argv, since there is a null at
11316 the end that can be overwritten, and this way there's no need to
11317 worry about size-calculation overflow.
11318 (sort_args): Check for size-calculation overflow.
11320 * eval.c (init_eval_once, grow_specpdl): Don't update size until

11326 Check for integer overflow.
11327 (x_set_alpha): Do not assume XINT fits in int.
11329 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
11330 This is for the members text_lines, text_cols, total_lines, total_cols,
11331 where the system imposes an 'int' limit.
11333 * fringe.c (Fdefine_fringe_bitmap):
11334 Don't update size until alloc works.

11339 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
11340 Check for size-calculation overflow.
11341 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
11342 do, as we prefer signed integers.

11349 * gtkutil.h: Change prototypes to match the above.
11351 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

11398 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
11399 for command line length. Do not attempt to address one before the
11400 beginning of an array, as that's not portable.

11446 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
11447 (X_LONG_MIN): New macros.
11448 Use them to make the following changes clearer.
11449 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
11450 This change doesn't affect the value now, but it may help remind
11451 future maintainers not to raise the value too much later.
11452 (SELECTION_QUANTUM): Remove, replacing with ...
11453 (selection_quantum): ... new function, which avoids overflow.
11455 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
11456 assumption that selection length fits in 'int'.

11473 Don't store size until memory allocation succeeds.
11474 (x_get_window_property): Plug memory leak on memory exhaustion.
11475 Don't double-block input; malloc is safe here. Don't assume 2**34
11476 - 4 fits in unsigned long. Add an xassert to check
11477 XGetWindowProperty overflow. Be more careful about overflow
11478 calculations, and distinguish size from memory overflow better.
11479 (receive_incremental_selection): When tracing, don't assume
11480 unsigned int is less than INT_MAX.
11481 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

11484 in the range -65535 through -1 fit in an X unsigned short.
11485 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
11486 result parameters unless successful. Rely on cons_to_unsigned
11487 to report problems with elements; the old code wasn't right anyway.
11488 (x_check_property_data): Check for int overflow; we cannot use
11489 a wider type due to X limits.

11522 * lisp.h (hash_lookup, hash_put):
11523 * minibuf.c (Ftest_completion):
11524 Use ptrdiff_t for hash table indexes, not int (which is too
11525 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on

11528 * charset.c (Fdefine_charset_internal): Check for integer overflow.
11529 Add a FIXME comment about memory leaks.

11537 with outlandish widths.
11538 * character.h (sanitize_tab_width): Rename from sanitize_width,
11539 now that we have two such functions. All uses changed.

11564 (make_lispy_movement): Use same integer type in forward decl
11565 that is used in the definition.

11567 Change bufsize argument back to int, undoing my 2011-03-30 change.
11568 We prefer signed types, and int is wide enough here.
11569 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
11570 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
11571 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
11572 length, not size_t. Use ptrdiff_t for index, not int.
11573 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
11574 possibility of integer overflow.

11602 Prefer int to unsigned where either will do.
11603 (tiff_handler): New function, combining the cores of the
11604 old tiff_error_handler and tiff_warning_handler.
11605 This function is rewritten to use vsnprintf and thereby avoid
11606 stack buffer overflows. It uses only the features of vsnprintf
11607 that are common to both POSIX and native Microsoft.
11608 (tiff_error_handler, tiff_warning_handler): Use it.
11609 (tiff_load, gif_load, imagemagick_load_image):
11610 Don't assume :index value fits in 'int'.

11613 the integer types that MagickCropImage accepts. Don't assume
11614 Vimagemagick_render_type has a nonnegative value. Don't assume

11631 `(space ...)', and specifies display in the text area, return 2
11633 (try_cursor_movement): Check for the need to scroll more
11634 accurately, and prefer exact match for point under bidi.
11635 Don't advance `row' beyond the last row of the window.
11637 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
11638 into disp_prop; all users changed.

11653 buffers, return left-to-right.
11654 (set_cursor_from_row): Consider candidate row a win if its glyph
11655 represents a newline and point is on that newline. Fixes cursor
11656 positioning on the newline at EOL of R2L text within L2R
11657 paragraph, and vice versa.
11658 (try_cursor_movement): Check continued rows, in addition to
11659 continuation rows. Fixes unwarranted scroll when point enters a
11660 continued line of R2L text within an L2R paragraph, or vice versa.
11661 (cursor_row_p): Consider the case of point being equal to
11662 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
11663 from the end of a short line to the beginning of a continued line
11664 of R2L text within L2R paragraph.

11688 * xdisp.c (redisplay_window): When computing centering_position,
11689 account for the height of the header line. (Bug#8874)
11691 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
11692 instead of CHAR_TO_BYTE. Fixes a crash when a completion
11693 candidate is selected by the mouse, and that candidate has a
11694 composed character under the mouse.
11696 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
11697 coordinates reported by pos-visible-in-window-p for a composed
11698 character in column zero.
11700 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

11706 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
11707 consider it a hit if to_charpos is anywhere in the range of the
11708 composed buffer positions.
11710 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
11712 * image.c (gif_load): Don't assume that each subimage has the same
11713 dimensions as the base image. Handle disposal method that is
11714 "undefined" by the gif spec (Bug#9335).
11716 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
11718 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
11719 (Fcondition_case): Document `debug' symbol in error handler.
11721 2011-08-19 Eli Zaretskii <eliz@gnu.org>
11723 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
11724 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
11725 from an Org mode buffer to a Speedbar frame.
11727 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
11728 a composition, take its buffer position from IT->cmp_it.charpos.
11729 Fixes cursor positioning at the beginning of a line that begins
11730 with a composed character.
11732 2011-08-18 Eli Zaretskii <eliz@gnu.org>
11734 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
11735 character bidirectional type, use STRONG_L instead. Fixes crashes
11736 in a buffer produced by `describe-categories'.
11738 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
11739 members before the level stack, so they would be saved and
11740 restored when copying iterator state. Fixes incorrect reordering
11741 around TABs covered by display properties.
11743 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
11745 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

11750 (internal_condition_case_2, internal_condition_case_n):
11751 Remove unnecessary aborts (Bug#9081).
11753 2011-08-17 Eli Zaretskii <eliz@gnu.org>
11755 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
11756 has no `load' handler, try opening the file locally. (Bug#9311)
11758 2011-08-16 Ken Brown <kbrown@cornell.edu>
11760 * gmalloc.c: Expand comment.

11815 * xdisp.c (move_it_in_display_line_to): Don't invoke
11816 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
11817 ppos_it. Fixes vertical cursor motion when line beginning is
11818 covered by an image. (Bug#9296)
11820 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
11822 * nsterm.h (ns_run_ascript): Declare.

11827 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
11828 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
11829 the event loop. Get status from as_status (Bug#7276).
11831 * nsterm.m (sendEvent): If event is NSApplicationDefined and
11832 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
11833 the event loop (Bug#7276).
11835 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
11837 * gnutls.c (QCgnutls_bootprop_priority)

11859 (Fnetwork_interface_list): Allocate in increments of bytes instead
11860 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
11861 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
11863 (struct ifflag_def): notrailers is smart on OSX.
11864 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
11865 Get hardware address with getifaddrs if available.

11869 * xdisp.c (iterate_out_of_display_property): xassert that
11870 IT->position is set to within IT->object's boundaries. Break from
11871 the loop as soon as EOB is reached; avoids infloops in redisplay
11872 when IT->position is set up wrongly due to some bug.
11873 Set IT->current to match the bidi iterator unconditionally.
11874 (push_display_prop): Allow GET_FROM_STRING as IT->method on
11875 entry. Force push_it to save on the stack the current
11876 buffer/string position, to be restored by pop_it. Fix flags in
11877 the iterator structure wrt the object coming from a display
11878 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
11879 properties. (Bug#9284)
11881 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
11883 * fontset.c (fontset_get_font_group): Add proper type checks.

11922 longlines-mode. (Bug#9254)
11923 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
11924 word-wrap under bidirectional display. (Bug#9224)
11926 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
11927 is non-zero, even if the data buffer is NULL. Fixes a crash in
11928 vertical-motion with longlines-mode. (Bug#9254)
11930 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11932 * bidi.c <bidi_cache_total_alloc>: Now static.

11938 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
11939 amount allocated this far in `bidi_cache_total_alloc'.
11940 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
11941 non-zero, only free the data buffer without restoring the cache
11942 contents. All callers changed.
11944 * dispextern.h (bidi_unshelve_cache): Update prototype.
11946 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)

11948 (move_it_vertically_backward, move_it_by_lines): Replace the call
11949 to xfree to an equivalent call to bidi_unshelve_cache.
11950 (move_it_in_display_line_to): Fix logic of returning
11951 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)

12007 DISP_PROP_P, and pass it to compute_display_string_pos.
12008 Only handle text covered by a display string if DISP_PROP_P is returned
12009 non-zero. All callers of bidi_fetch_char changed.

12110 string position if the buffer had its restriction changed.
12113 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12115 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12117 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12119 Integer signedness and overflow and related fixes. (Bug#9079)
12121 * bidi.c: Integer size and overflow fixes.
12122 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
12123 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
12124 (bidi_cache_find_level_change, bidi_cache_ensure_space)
12125 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
12126 (bidi_find_other_level_edge):
12127 Use ptrdiff_t instead of EMACS_INT where either will do.
12128 This works better on 32-bit hosts configured --with-wide-int.
12129 (bidi_cache_ensure_space): Check for size-calculation overflow.
12130 Use % rather than repeated addition, for better worst-case speed.
12131 Don't set bidi_cache_size until after xrealloc returns, because it
12133 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
12134 (bidi_cache_ensure_space): Also check that the bidi cache size
12135 does not exceed that of the largest Lisp string or buffer. See Eli
12136 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
12138 * alloc.c (__malloc_size_t): Remove.
12139 All uses replaced by size_t. See Andreas Schwab's note
12140 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
12142 * image.c: Improve checking for integer overflow.
12143 (check_image_size): Assume that f is nonnull, since
12144 it is always nonnull in practice. This is one less thing to
12145 worry about when checking for integer overflow later.
12146 (x_check_image_size): New function, which checks for integer
12147 overflow issues inside X.
12148 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
12149 This removes the need for a memory_full check.
12150 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
12151 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
12152 (xbm_read_bitmap_data): Change locals back to 'int', since
12153 their values must fit in 'int'.
12154 (xpm_load_image, png_load, tiff_load):
12155 Invoke x_create_x_image_and_pixmap earlier,
12156 to avoid much needless work if the image is too large.
12157 (tiff_load): Treat overly large images as if
12158 x_create_x_image_and_pixmap failed, not as malloc failures.
12159 (gs_load): Use x_check_image_size.
12161 * gtkutil.c: Omit integer casts.
12162 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
12163 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
12165 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
12167 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
12168 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
12169 would wrongly return t on a 64-bit host.
12171 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
12172 The plain *_OVERFLOW macros run afoul of GCC bug 49705
12173 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
12174 and therefore cause GCC to emit a bogus diagnostic in some cases.
12176 * image.c: Integer signedness and overflow and related fixes.
12177 This is not an exhaustive set of fixes, but it's time to
12178 record what I've got.
12179 (lookup_pixel_color, check_image_size): Remove redundant decls.
12180 (check_image_size): Don't assume that arbitrary EMACS_INT values
12181 fit in 'int', or that arbitrary 'double' values fit in 'int'.
12182 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
12183 (tiff_load, imagemagick_load_image):
12184 Check for overflow in size calculations.
12185 (x_create_x_image_and_pixmap): Remove unnecessary test for
12186 xmalloc returning NULL; that can't happen.
12187 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
12188 (xpm_color_bucket): Use better integer hashing function.
12189 (xpm_cache_color): Don't possibly over-allocate memory.
12190 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
12191 (gif_memory_source):
12192 Use ptrdiff_t, not int or size_t, to record sizes.
12193 (png_load): Don't assume values greater than 2**31 fit in 'int'.
12194 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
12195 either works, as we prefer signed integers.
12196 (tiff_read_from_memory, tiff_write_from_memory):
12197 Return tsize_t, not size_t, since that's what the TIFF API wants.
12198 (tiff_read_from_memory): Don't fail simply because the read would
12199 go past EOF; instead, return a short read.
12200 (tiff_load): Omit no-longer-needed casts.
12201 (Fimagemagick_types): Don't assume size fits into 'int'.
12203 Improve hashing quality when configured --with-wide-int.
12204 * fns.c (hash_string): New function, taken from sxhash_string.
12205 Do not discard information about ASCII character case; this
12206 discarding is no longer needed.
12207 (sxhash-string): Use it. Change sig to match it. Caller changed.
12208 * lisp.h: Declare it.
12209 * lread.c (hash_string): Remove, since we now use fns.c's version.
12210 The fns.c version returns a wider integer if --with-wide-int is
12211 specified, so this should help the quality of the hashing a bit.
12213 * emacs.c: Integer overflow minor fix.
12214 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
12215 Define only if GNU_LINUX.
12216 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
12218 * dispnew.c: Integer signedness and overflow fixes.
12219 Remove unnecessary forward decls, that were a maintenance hassle.
12220 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
12222 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
12223 (scrolling_window): Use ptrdiff_t, not int, for byte count.
12224 (prepare_desired_row, line_draw_cost):
12225 Use int, not unsigned, where either works.
12226 (save_current_matrix, restore_current_matrix):
12227 Use ptrdiff_t, not size_t, where either works.
12228 (init_display): Check for overflow more accurately, and without
12229 relying on undefined behavior.
12231 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
12232 Remove, replacing with the new symbols in lisp.h. All uses changed.
12233 * fileio.c (make_temp_name):
12234 * filelock.c (lock_file_1, lock_file):
12235 * xdisp.c (message_dolog):
12236 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
12237 Use pMd etc. instead.
12238 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
12239 replacing the pWIDE etc. symbols removed from editfns.c.
12241 * keyboard.h (num_input_events): Now uintmax_t.
12242 This is (very slightly) less likely to mess up due to wraparound.
12245 * buffer.c: Integer signedness fixes.
12246 (alloc_buffer_text, enlarge_buffer_text):
12247 Use ptrdiff_t rather than size_t when either will do, as we prefer
12250 * alloc.c: Integer signedness and overflow fixes.
12251 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
12252 (__malloc_size_t): Default to size_t, not to int.
12253 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
12254 (Fgarbage_collect, mark_object_loop_halt, mark_object):
12255 Prefer ptrdiff_t to size_t when either would do, as we prefer
12257 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
12258 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
12259 Now const. Initialize with values that are in range even if char
12261 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
12262 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
12263 These functions do the right thing with sizes > 2**32.
12264 (check_depth): Now ptrdiff_t, not int.
12265 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
12266 Adjust to new way of storing sizes. Check for size overflow bugs
12268 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
12269 slightly wrong anyway, as it missed one instance of
12270 XMALLOC_OVERRUN_CHECK_OVERHEAD.
12271 (refill_memory_reserve): Omit needless cast to size_t.
12272 (mark_object_loop_halt): Mark as externally visible.
12274 * xselect.c: Integer signedness and overflow fixes.
12275 (Fx_register_dnd_atom, x_handle_dnd_message):
12276 Use ptrdiff_t, not size_t, since we prefer signed.
12277 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
12278 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
12279 x_dnd_atoms_size and x_dnd_atoms_length.
12281 * doprnt.c: Prefer signed to unsigned when either works.
12283 * doprnt.c (doprnt):
12285 * xdisp.c (vmessage):
12286 Use ptrdiff_t, not size_t, when using or implementing doprnt,
12287 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
12288 prefer signed arithmetic to avoid comparison confusion.
12289 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
12290 but is a bit tricky.
12292 Assume freestanding C89 headers, string.h, stdlib.h.
12293 * data.c, doprnt.c, floatfns.c, print.c:
12294 Include float.h unconditionally.
12295 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
12296 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
12297 * regex.c: Likewise for stddef.h, string.h.
12298 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
12299 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
12300 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
12301 (STDC_HEADERS): Remove obsolete defines.
12302 * sysdep.c: Include limits.h unconditionally.
12304 Assume support for memcmp, memcpy, memmove, memset.
12305 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
12306 * regex.c (memcmp, memcpy):
12307 Remove; we assume C89 now.
12309 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
12310 (__malloc_safe_bcopy): Remove; no longer needed.
12312 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
12313 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
12314 well either way, and we prefer signed to unsigned.
12316 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
12318 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
12319 closes the connection while we're reading (bug#9182).
12321 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
12323 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
12324 are specified (Bug#9168).
12326 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
12328 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
12329 Found by GCC static checking and --with-wide-int on a 32-bit host.
12331 2011-07-25 Eli Zaretskii <eliz@gnu.org>
12333 * xdisp.c (compute_display_string_pos): Fix logic of caching
12334 previous display string position. Initialize cached_prev_pos to
12335 -1. Fixes slow-down at the beginning of a buffer.
12337 2011-07-24 Eli Zaretskii <eliz@gnu.org>
12339 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
12340 for attrs[LFACE_FONTSET_INDEX].
12342 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
12344 * xml.c (parse_region): Remove unused local
12345 that was recently introduced.
12347 2011-07-23 Eli Zaretskii <eliz@gnu.org>
12349 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
12350 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
12352 * xdisp.c (move_it_in_display_line_to): Record the best matching
12353 position for TO_CHARPOS while scanning the line, and restore it on
12354 exit if none of the characters scanned was an exact match.
12355 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
12356 when exact match is impossible due to invisible text, and the
12357 lines are truncated.
12359 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
12361 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
12364 2011-07-22 Eli Zaretskii <eliz@gnu.org>
12366 Fix a significant slow-down of cursor motion with C-n, C-p,
12367 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
12368 auto-repeat under bidi redisplay in fontified buffers.
12369 * xdisp.c (compute_stop_pos_backwards): New function.
12370 (next_element_from_buffer): Call compute_stop_pos_backwards to
12371 find a suitable prev_stop when we find ourselves before
12373 (reseat): Don't look for prev_stop, as that could mean a very long
12375 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
12376 <cached_disp_overlay_modiff>: Cache for last found display string
12378 (compute_display_string_pos): Return the cached position if asked
12379 about the same buffer in the same area of character positions, and
12380 the buffer wasn't changed since the time the display string
12381 position was cached.
12383 2011-07-22 Eli Zaretskii <eliz@gnu.org>
12385 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
12386 is an integer, which is important for empty lines. (Bug#9149)
12388 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
12390 * frame.c (Fmodify_frame_parameters): In tty case, update the
12391 default face if necessary (Bug#4238).
12393 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
12395 * editfns.c (Fstring_to_char): No need to explain what a character
12396 is in the docstring (Bug#6576).
12398 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
12400 * xml.c (parse_region): Make sure we always return a tree.
12402 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
12404 * xml.c (parse_region): If a document contains only comments,
12407 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
12409 * xml.c (make_dom): Return comments, too.
12411 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
12414 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
12415 and the surrounding thread.
12416 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
12417 rather than fgets, and retry after EINTR. Otherwise, 'emacs
12418 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
12420 * s/openbsd.h (BROKEN_SIGIO): Define.
12421 * unexelf.c (unexec) [__OpenBSD__]:
12422 Don't update the .mdebug section of the Alpha COFF symbol table.
12424 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12426 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
12429 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
12431 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
12432 This fixes some race conditions on the permissions of any newly
12435 * alloc.c (valid_pointer_p): Use pipe, not open.
12436 This fixes some permissions issues when debugging.
12438 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
12439 If fchown fails to set both uid and gid, try to set just gid,
12440 as that is sometimes allowed. Adjust the file's mode to eliminate
12441 setuid or setgid bits that are inappropriate if fchown fails.
12443 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
12445 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
12446 to compare Lisp_Objects.
12447 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
12448 global_gnutls_log_level, don't mistake it for a Lisp_Object.
12449 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
12451 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
12453 * lread.c (read_integer): Unread even EOF character.
12454 (read1): Likewise. Properly record start position of symbol.
12456 * lread.c (read1): Read `#:' as empty uninterned symbol if no
12457 symbol character follows.
12459 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
12461 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
12462 This works around a problem with the previous change to Fcopy_file.
12463 Recent glibc declares fchown with __attribute__((warn_unused_result)),
12464 and without this change, GCC might complain about discarding
12465 fchown's return value.
12467 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
12469 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
12471 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
12473 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
12475 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
12477 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
12478 it's used from the C level.
12480 * process.c: Use the same condition for POLL_FOR_INPUT in both
12481 keyboard.c and process.c (bug#1858).
12483 2011-07-09 Lawrence Mitchell <wence@gmx.li>
12485 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
12486 (Fgnutls_boot): Use it.
12488 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
12490 * doc.c (Fsubstitute_command_keys): Revert last change.
12492 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
12494 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
12495 quotes the next character, and doesn't affect other longer
12496 sequences (bug#8935).
12498 * lread.c (syms_of_lread): Clarify that is isn't only
12499 `eval-buffer' and `eval-defun' that's affected by
12500 `lexical-binding' (bug#8460).
12502 2011-07-15 Eli Zaretskii <eliz@gnu.org>
12504 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
12505 bidi redisplay when a line includes both an image and is truncated.
12507 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
12509 Fix minor problems found by static checking.
12510 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
12511 (elsz): Now a signed constant, not a size_t var. We prefer signed
12512 types to unsigned, to avoid integer comparison confusion. Without
12513 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
12514 "cannot optimize loop, the loop counter may overflow", a symptom
12516 * indent.c (Fvertical_motion): Mark locals as initialized.
12517 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
12519 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
12521 * search.c (Fre_search_backward): Mention `case-fold-search' in
12522 all the re_search_* functions (bug#8138).
12524 * keyboard.c (Fopen_dribble_file): Document when the file is
12527 2011-07-14 Eli Zaretskii <eliz@gnu.org>
12529 * bidi.c (bidi_dump_cached_states): Fix format of displaying
12532 Support bidi reordering of display and overlay strings.
12533 * xdisp.c (compute_display_string_pos)
12534 (compute_display_string_end): Accept additional argument STRING.
12535 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
12536 (reseat_to_string): Initialize bidi_it->string.s and
12537 bidi_it->string.schars.
12538 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
12539 NULL (avoids a crash in bidi_paragraph_init).
12540 Initialize itb.string.lstring.
12541 (init_iterator): Call bidi_init_it only of a valid
12542 buffer position was specified. Initialize paragraph_embedding to
12544 (reseat_to_string): Initialize the bidi iterator.
12545 (display_string): If we need to ignore text properties of
12546 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
12547 original value of -1 will not work with bidi.)

13041 (clone_per_buffer_values): Don't assume that

13043 This isn't true in general, and it's particularly not true
13044 if Emacs is configured with --with-wide-int.
13045 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
13046 New macros, used in the buffer.c change.

13082 Random fixes. E.g., (random) never returned negative values.
13083 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
13084 subseconds part to the entropy, as that's a bit more random.
13085 Prefer signed to unsigned, since the signedness doesn't matter and
13086 in general we prefer signed. When given a limit, use a
13087 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
13088 latter isn't right if USE_2_TAGS_FOR_INTS.
13089 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
13090 not 0..VALMASK. Don't discard "excess" bits that random () returns.

13094 * textprop.c (text_property_stickiness):
13095 Obey Vtext_property_default_nonsticky.

13102 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
13103 This is more efficient than Ffile_directory_p and avoids a minor race.
13105 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
13107 * buffer.c (Foverlay_put): Say what the return value is
13110 * fileio.c (barf_or_query_if_file_exists): Check first if the file
13111 is a directory before asking whether to use the file name
13113 (barf_or_query_if_file_exists): Make the "File is a directory"
13114 error be more correct.
13116 * fns.c (Frequire): Remove the mention of the .gz files, since
13117 that's installation-specific, but keep the mention of
13118 `get-load-suffixes'.

13128 (syms_of_gnutls): Remove duplicate DEFSYM for
13129 Qgnutls_bootprop_verify_hostname_error, an error for
13130 Qgnutls_bootprop_verify_error (which is no longer used).
13132 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
13133 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
13134 Also (re)move comments that are misplaced or no longer relevant.
13136 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13138 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

13197 (syms_of_keymap): Defsubr make-composed-keymap.
13198 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

13235 * eval.c (struct backtrace): Simplify and port the data structure.
13236 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
13237 signed bit field, as this assumption is not portable and it makes
13238 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
13239 "char debug_on_exit : 1" as this is not portable either; instead,
13240 use the portable "unsigned int debug_on_exit : 1". Remove unused
13241 member evalargs. Remove obsolete comments about cc bombing out.
13243 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
13245 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

13423 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
13425 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
13427 * lread.c: Integer overflow fixes.
13428 (read_integer): Radix is now EMACS_INT, not int,
13429 to improve quality of diagnostics for out-of-range radices.
13430 Calculate buffer size correctly for out-of-range radices.
13431 (read1): Check for integer overflow in radices, and in
13432 read-circle numbers.
13433 (read_escape): Avoid int overflow.
13434 (Fload, openp, read_buffer_size, read1)
13435 (substitute_object_recurse, read_vector, read_list, map_obarray):
13436 Use ptrdiff_t, not int, for sizes.
13437 (read1): Use EMACS_INT, not int, for sizes.
13438 Check for size overflow.
13440 * image.c (cache_image): Check for size arithmetic overflow.
13442 * lread.c: Integer overflow issues.
13443 (saved_doc_string_size, saved_doc_string_length)

13445 Now ptrdiff_t, not int.
13446 (read1): Don't assume doc string length fits in int. Check for

13451 2011-06-22 Leo Liu <sdl.web@gmail.com>
13453 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
13454 Move to minibuffer.el.
13456 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
13458 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
13459 The following patches are for when GLYPH_DEBUG && !XASSERT.
13460 * dispextern.h (trace_redisplay_p, dump_glyph_string):
13461 * dispnew.c (flush_stdout):
13462 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
13463 Mark as externally visible.
13464 * dispnew.c (check_window_matrix_pointers): Now static.
13465 * dispnew.c (window_to_frame_vpos):
13466 * xfns.c (unwind_create_frame):
13467 * xterm.c (x_check_font): Remove unused local.
13468 * scroll.c (CHECK_BOUNDS):
13469 * xfaces.c (cache_fache): Rename local to avoid shadowing.
13470 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
13471 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
13472 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
13473 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
13475 (debug_method_add): Use va_list and vsprintf rather than relying
13476 on undefined behavior with wrong number of arguments.
13477 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
13478 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
13479 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
13480 since we're not interested in debugging glyphs with old libraries.
13481 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
13482 GCC 4.6.0's static checking.
13484 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
13486 Integer overflow and signedness fixes (Bug#8873).

13495 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
13496 (x_create_bitmap_from_xpm_data):
13497 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
13498 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
13500 * xfaces.c (load_pixmap):
13501 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
13502 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
13503 (.bitmaps_last, struct x_output.icon_bitmap):
13504 Use ptrdiff_t, not int, for bitmap indexes.
13505 (x_allocate_bitmap_record): Check for size overflow.
13506 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
13508 Use ptrdiff_t, not int, for overlay counts.
13509 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
13510 * editfns.c (overlays_around, get_pos_property):
13511 * textprop.c (get_char_property_and_overlay):
13512 * xdisp.c (next_overlay_change, note_mouse_highlight):
13513 * xfaces.c (face_at_buffer_position):
13514 * buffer.c (OVERLAY_COUNT_MAX): New macro.
13515 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
13516 (Fnext_overlay_change, Fprevious_overlay_change)
13517 (mouse_face_overlay_overlaps, Foverlays_in):
13518 Use ptrdiff_t, not int, for sizes.
13519 (overlays_at, overlays_in): Check for size-calculation overflow.
13521 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
13523 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
13524 (x_session_initialize): Do not assume string length fits in int.
13526 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
13527 This is unlikely, but can occur if DPI is outlandish.
13529 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
13530 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
13532 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
13533 * xrdb.c (magic_file_p, search_magic_path):
13534 Omit last arg SUFFIX; it was always 0. All callers changed.
13535 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
13537 * xfont.c (xfont_match): Avoid need for strlen.
13539 * xfns.c: Don't assume strlen fits in int.
13540 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
13542 * xdisp.c (message_log_check_duplicate): Return intmax_t,
13543 not unsigned long, as we prefer signed integers. All callers changed.
13544 Detect integer overflow in repeat count.
13545 (message_dolog): Don't assume print length fits in 39 bytes.
13546 (display_mode_element): Don't assume strlen fits in int.
13548 * termcap.c: Don't assume sizes fit in int and never overflow.
13549 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
13550 (gobble_line): Check for size-calculation overflow.
13552 * minibuf.c (Fread_buffer):
13553 * lread.c (intern, intern_c_string):
13554 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
13555 Don't assume string length fits in int.
13557 * keyboard.c (parse_tool_bar_item):
13558 * gtkutil.c (style_changed_cb): Avoid need for strlen.
13560 * font.c: Don't assume string length fits in int.
13561 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
13562 Use ptrdiff_t, not int.
13563 (font_intern_prop): Don't assume string length fits in int.
13564 Don't assume integer property fits in fixnum.
13565 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
13567 * filelock.c: Fix some buffer overrun and integer overflow issues.
13568 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
13569 Reformulate so as not to need the command string.
13570 Invoke gzip -cd rather than gunzip, as it's more portable.
13571 (lock_info_type, lock_file_1, lock_file):
13572 Don't assume pid_t and time_t fit in unsigned long.
13573 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
13574 (current_lock_owner): Prefer signed type for sizes.
13575 Use memcpy, not strncpy, where memcpy is what is really wanted.
13576 Don't assume (via atoi) that time_t and pid_t fit in int.
13577 Check for time_t and/or pid_t out of range, e.g., via a network share.
13578 Don't alloca where an auto var works fine.
13580 * fileio.c: Fix some integer overflow issues.
13581 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
13582 Don't assume string length fits in int.
13583 (directory_file_name): Don't assume string length fits in long.
13584 (make_temp_name): Don't assume pid fits in int, or that its print
13585 length is less than 20.
13587 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
13589 * coding.c (make_subsidiaries): Don't assume string length fits in int.
13591 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
13593 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
13594 We prefer signed integers, even for size calculations.
13596 * emacs.c: Don't assume string length fits in 'int'.
13597 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
13598 (main): Don't invoke strlen when not needed.
13600 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
13601 (XD_DEBUG_MESSAGE): Don't waste a byte.
13603 * callproc.c (getenv_internal_1, getenv_internal)
13604 (Fgetenv_internal):
13605 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
13607 * lread.c (invalid_syntax): Omit length argument.
13608 All uses changed. This doesn't fix a bug, but it simplifies the
13609 code away from its former Hollerith-constant appearance, and it's
13610 one less 'int' to worry about when looking at integer-overflow issues.
13611 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
13613 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
13614 This didn't break anything, but it didn't help either.
13615 It's confusing to put a bogus integer in a place where the actual
13616 value does not matter.
13617 (LIST_END_P): Remove unused macro and its bogus comment.
13618 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
13620 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
13621 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
13623 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
13624 We prefer signed types, and the value cannot exceed the EMACS_INT
13625 range anyway (because otherwise the length would not be representable).
13626 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
13627 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
13628 This avoids a GCC warning when WIDE_EMACS_INT.
13630 * indent.c (sane_tab_width): New function.
13631 (current_column, scan_for_column, Findent_to, position_indentation)
13632 (compute_motion): Use it. This is just for clarity.
13633 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
13635 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
13637 * lisp.h (lint_assume): New macro.
13638 * composite.c (composition_gstring_put_cache):
13639 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
13641 * editfns.c, insdel.c:
13642 Omit unnecessary forward decls, to simplify future changes.
13644 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
13646 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
13648 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
13649 Use much-faster test for byte-length change.
13650 Don't assume string byte-length fits in 'int'.
13651 Check that character arg fits in 'int'.
13652 (mapcar1): Declare byte as byte, for clarity.
13654 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
13656 * fns.c (concat): Catch string overflow earlier.
13657 Do not rely on integer wraparound.
13659 * dispextern.h (struct it.overlay_strings_charpos)
13660 (struct it.selective): Now EMACS_INT, not int.
13661 * xdisp.c (forward_to_next_line_start)
13662 (back_to_previous_visible_line_start)
13663 (reseat_at_next_visible_line_start, next_element_from_buffer):
13664 Don't arbitrarily truncate the value of 'selective' to int.
13666 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
13668 * composite.c: Don't truncate sizes to 'int'.
13669 (composition_gstring_p, composition_reseat_it)
13670 (composition_adjust_point): Use EMACS_INT, not int.
13671 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
13672 not EMACS_UINT, for indexes.
13674 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
13676 * buffer.c: Include <verify.h>.
13677 (struct sortvec.priority, struct sortstr.priority):
13678 Now EMACS_INT, not int.
13679 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
13680 (struct sortstr.size, record_overlay_string)
13681 (struct sortstrlist.size, struct sortlist.used):
13682 Don't truncate size to int.
13683 (record_overlay_string): Check for size-calculation overflow.
13684 (init_buffer_once): Check at compile-time, not run-time.
13686 2011-06-22 Jim Meyering <meyering@redhat.com>
13688 Don't leak an XBM-image-sized buffer
13689 * image.c (xbm_load): Free the image buffer after using it.
13691 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
13694 * composite.c (find_automatic_composition): Omit needless 'return 0;'
13695 that Sun C diagnosed.
13696 * fns.c (secure_hash): Fix pointer signedness issue.
13697 * intervals.c (static_offset_intervals): New function.
13698 (offset_intervals): Use it.
13700 2011-06-21 Leo Liu <sdl.web@gmail.com>
13703 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
13706 * fns.c (secure_hash): Rename from crypto_hash_function and change
13707 the first arg to accept symbols.
13708 (Fsecure_hash): New primitive.
13709 (syms_of_fns): New symbols.
13711 2011-06-20 Deniz Dogan <deniz@dogan.se>
13713 * process.c (Fset_process_buffer): Clarify return value in
13716 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
13718 * dispnew.c (add_window_display_history): Use BVAR.
13720 * xdisp.c (debug_method_add): Use BVAR.
13721 (check_window_end, dump_glyph_matrix, dump_glyph)
13722 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
13724 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
13727 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
13728 check till after the cache is created in init_frame_faces.
13730 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
13732 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
13734 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
13736 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
13737 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
13738 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
13740 Improve buffer-overflow checking (Bug#8873).
13741 * fileio.c (Finsert_file_contents):
13742 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
13743 Remove the old (too-loose) buffer overflow checks.
13744 They weren't needed, since make_gap checks for buffer overflow.
13745 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
13746 The old code merely checked for Emacs fixnum overflow, and relied
13747 on undefined (wraparound) behavior. The new code avoids undefined
13748 behavior, and also checks for ptrdiff_t and/or size_t overflow.
13750 * editfns.c (Finsert_char): Don't dump core with very negative counts.
13751 Tune. Don't use wider integers than needed. Don't use alloca.
13752 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
13754 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
13756 * insdel.c, lisp.h (buffer_overflow): New function.
13757 (insert_from_buffer_1, replace_range, replace_range_2):
13758 * insdel.c (make_gap_larger):
13759 * editfns.c (Finsert_char):
13760 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
13762 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
13764 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
13766 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
13768 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
13769 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
13771 * fileio.c: Don't assume EMACS_INT fits in off_t.
13772 (emacs_lseek): New static function.
13773 (Finsert_file_contents, Fwrite_region): Use it.
13774 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
13776 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
13778 * fns.c: Don't overflow int when computing a list length.
13779 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
13780 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
13781 truncation on 64-bit hosts. Check for QUIT every
13782 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
13783 faster and is responsive enough.
13784 (Flength): Report an error instead of overflowing an integer.
13785 (Fsafe_length): Return a float if the value is not representable
13786 as a fixnum. This shouldn't happen except in contrived situations.
13787 (Fnthcdr, Fsort): Don't assume list length fits in int.
13788 (Fcopy_sequence): Don't assume vector length fits in int.
13790 * alloc.c: Check that resized vectors' lengths fit in fixnums.
13791 (header_size, word_size): New constants.
13792 (allocate_vectorlike): Don't check size overflow here.
13793 (allocate_vector): Check it here instead, since this is the only
13794 caller of allocate_vectorlike that could cause overflow.
13795 Check that the new vector's length is representable as a fixnum.
13797 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
13798 The previous code was bogus. For example, next_almost_prime (32)
13799 returned 39, which is undesirable as it is a multiple of 3; and
13800 next_almost_prime (24) returned 25, which is a multiple of 5 so
13801 why was the code bothering to check for multiples of 7?
13803 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
13805 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
13807 Variadic C functions now count arguments with ptrdiff_t.
13808 This partly undoes my 2011-03-30 change, which replaced int with size_t.
13809 Back then I didn't know that the Emacs coding style prefers signed int.
13810 Also, in the meantime I found a few more instances where arguments
13811 were being counted with int, which may truncate counts on 64-bit
13812 machines, or EMACS_INT, which may be unnecessarily wide.
13813 * lisp.h (struct Lisp_Subr.function.aMANY)
13814 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
13815 Arg counts are now ptrdiff_t, not size_t.
13816 All variadic functions and their callers changed accordingly.
13817 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
13818 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
13819 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
13820 * callint.c (Fcall_interactively): Check arg count for overflow,
13821 to avoid potential buffer overrun. Use signed char, not 'int',
13822 for 'varies' array, so that we needn't bother to check its size
13823 calculation for overflow.
13824 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
13825 * eval.c (apply_lambda):
13826 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
13827 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
13828 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
13830 * callint.c (Fcall_interactively): Don't use index var as event count.
13832 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
13833 * mem-limits.h (SIZE): Remove; no longer used.
13835 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
13837 Remove unnecessary casts.
13838 * xterm.c (x_term_init):
13839 * xfns.c (x_set_border_pixel):
13840 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
13841 These aren't needed now that we assume ANSI C.
13843 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
13844 It's more likely to cause problems (due to unsigned overflow)
13847 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
13849 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
13851 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
13853 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
13855 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
13857 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
13859 GLYPH_CODE_FACE returns EMACS_INT, not int.
13860 * dispextern.h (merge_faces):
13861 * xfaces.c (merge_faces):
13862 * xdisp.c (get_next_display_element, next_element_from_display_vector):
13863 Don't assume EMACS_INT fits in int.
13865 * character.h (CHAR_VALID_P): Remove unused parameter.
13866 * fontset.c, lisp.h, xdisp.c: All uses changed.
13868 * editfns.c (Ftranslate_region_internal): Omit redundant test.
13870 * fns.c (concat): Minor tuning based on overflow analysis.
13871 This doesn't fix any bugs. Use int to hold character, instead
13872 of constantly refetching from Emacs object. Use XFASTINT, not
13873 XINT, for value known to be a character. Don't bother comparing
13874 a single byte to 0400, as it's always less.
13876 * floatfns.c (Fexpt):
13877 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
13879 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
13882 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
13884 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
13885 Without this fix, on a 64-bit host (aset S 0 4294967386) would
13886 incorrectly succeed when S was a string, because 4294967386 was
13887 truncated before it was used.
13889 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
13890 Otherwise, an out-of-range integer could cause undefined behavior
13893 * composite.c: Use int, not EMACS_INT, for characters.
13894 (fill_gstring_body, composition_compute_stop_pos): Use int, not
13895 EMACS_INT, for values that are known to be in character range.
13896 This doesn't fix any bugs but is the usual style inside Emacs and
13897 may generate better code on 32-bit machines.
13899 Make sure a 64-bit char is never passed to ENCODE_CHAR.
13900 This is for reasons similar to the recent CHAR_STRING fix.
13901 * charset.c (Fencode_char): Check that character arg is actually
13902 a character. Pass an int to ENCODE_CHAR.
13903 * charset.h (ENCODE_CHAR): Verify that the character argument is no
13904 wider than 'int', as a compile-time check to prevent future regressions
13907 * character.c (char_string): Remove unnecessary casts.
13909 Make sure a 64-bit char is never passed to CHAR_STRING.
13910 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
13911 by silently ignoring the top 32 bits, allowing some values
13912 that were far too large to be valid characters.
13913 * character.h: Include <verify.h>.
13914 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
13915 arguments are no wider than unsigned, as a compile-time check
13916 to prevent future regressions in this area.
13918 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
13919 (Fsubst_char_in_region):
13921 * xdisp.c (decode_mode_spec_coding):
13922 Adjust to CHAR_STRING's new requirement.
13923 * editfns.c (Finsert_char, Fsubst_char_in_region):
13924 * fns.c (concat): Check that character args are actually
13925 characters. Without this test, these functions did the wrong
13926 thing with wildly out-of-range values on 64-bit hosts.
13928 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
13929 These casts should not be needed on 32-bit hosts, either.
13930 * keyboard.c (read_char):
13931 * lread.c (Fload): Remove casts to unsigned.
13933 * lisp.h (UNSIGNED_CMP): New macro.
13934 This fixes comparison bugs on 64-bit hosts.
13935 (ASCII_CHAR_P): Use it.
13936 * casefiddle.c (casify_object):
13937 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
13938 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
13939 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
13940 * dispextern.h (FACE_FROM_ID):
13941 * keyboard.c (read_char): Use UNSIGNED_CMP.
13943 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
13944 not to EMACS_INT, to avoid GCC warning.
13946 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
13948 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
13949 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
13950 isn't needed on 32-bit machines.
13952 * buffer.c (Fgenerate_new_buffer_name):
13953 Use EMACS_INT for count, not int.
13954 (advance_to_char_boundary): Return EMACS_INT, not int.
13956 * data.c (Qcompiled_function): Now static.
13958 * window.c (window_body_lines): Now static.
13960 * image.c (gif_load): Rename local to avoid shadowing.
13962 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
13963 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
13964 * alloc.c (make_save_value): Integer argument is now of type
13965 ptrdiff_t, not int.
13966 (mark_object): Use ptrdiff_t, not int.
13967 * lisp.h (pD): New macro.
13968 * print.c (print_object): Use it.
13970 * alloc.c: Use EMACS_INT, not int, to count objects.
13971 (total_conses, total_markers, total_symbols, total_vector_size)
13972 (total_free_conses, total_free_markers, total_free_symbols)
13973 (total_free_floats, total_floats, total_free_intervals)
13974 (total_intervals, total_strings, total_free_strings):
13975 Now EMACS_INT, not int. All uses changed.
13976 (Fgarbage_collect): Compute overall total using a double, so that
13977 integer overflow is less likely to be a problem. Check for overflow
13978 when converting back to an integer.
13979 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
13980 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
13981 These were 'int' variables that could overflow on 64-bit hosts;
13982 they were never used, so remove them instead of repairing them.
13983 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
13984 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
13985 Previously, this ceilinged at INT_MAX, but that doesn't work on
13987 (allocate_pseudovector): Don't use EMACS_INT when int would do.
13989 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
13990 (allocate_vectorlike): Check for ptrdiff_t overflow.
13991 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
13992 when a (possibly-narrower) signed value would do just as well.
13993 We prefer using signed arithmetic, to avoid comparison confusion.
13995 * alloc.c: Catch some string size overflows that we were missing.
13996 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
13997 for convenience in STRING_BYTES_MAX.
13998 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
13999 The definition here is exact; the one in lisp.h was approximate.
14000 (allocate_string_data): Check for string overflow. This catches
14001 some instances we weren't catching before. Also, it catches
14002 size_t overflow on (unusual) hosts where SIZE_MAX <= min
14003 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
14004 and ptrdiff_t and EMACS_INT are both 64 bits.
14006 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
14007 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
14008 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
14010 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
14012 * alloc.c (Fmake_string): Check for out-of-range init.
14014 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
14016 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
14018 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
14020 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
14021 xg_get_default_scrollbar_width.
14023 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
14024 (int_gtk_range_get_value): Move to the scroll bar part of the file.
14025 (style_changed_cb): Call update_theme_scrollbar_width and call
14026 x_set_scroll_bar_default_width and xg_frame_set_char_size for
14027 all frames (Bug#8505).
14028 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
14029 Call gtk_window_set_resizable if HAVE_GTK3.
14030 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
14031 and height if HAVE_GTK3 (Bug#8505).
14032 (scroll_bar_width_for_theme): New variable.
14033 (update_theme_scrollbar_width): New function.
14034 (xg_get_default_scrollbar_width): Move code to
14035 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
14036 (xg_initialize): Call update_theme_scrollbar_width.
14038 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
14040 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
14042 2011-06-12 Martin Rudalics <rudalics@gmx.at>
14044 * frame.c (make_frame): Call other_buffer_safely instead of
14047 * window.c (temp_output_buffer_show): Call display_buffer with
14048 second argument Vtemp_buffer_show_specifiers and reset latter
14049 immediately after the call.
14050 (Vtemp_buffer_show_specifiers): New variable.
14051 (auto_window_vscroll_p, next_screen_context_lines)
14052 (Vscroll_preserve_screen_position): Remove leading asterisks from

14235 Remove static from declaration of Qdelete_window, it's
14236 temporarily needed by Fbury_buffer.
14237 (replace_window): Don't assign orig_top_line and

14603 (display_prop_intangible_p): Reimplement to call
14604 handle_display_spec instead of single_display_spec_intangible_p.

14616 value of a `display' property is a "replacing spec".
14617 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
14618 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

14648 * gnutls.c: Use Emacs's memory allocators.
14649 Without this change, the gnutls library would invoke malloc etc.
14650 directly, which causes problems on non-SYNC_INPUT hosts, and which
14651 runs afoul of improving memory_full behavior. (Bug#8761)
14652 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
14653 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
14654 xfree instead of the default malloc, realloc, free.
14655 (Fgnutls_boot): No need to check for memory allocation failure,
14656 since xmalloc does that for us.

14685 need to be updated by these changes.
14686 * fns.c (make_hash_table, maybe_resize_hash_table):
14687 Check for integer overflow with large hash tables.
14688 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
14689 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
14690 (SXHASH_REDUCE): New macro.
14691 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
14692 Use it instead of discarding useful hash info with large hash values.
14693 (sxhash_float): New function.
14694 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
14695 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
14696 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
14697 Rewrite to use FIXNUM_BITS, as this simplifies things.
14698 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
14699 Adjust signatures to match updated version of code.
14700 (consing_since_gc): Now EMACS_INT, since a single hash table can
14701 use more than INT_MAX bytes.

14724 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14726 Don't force ./temacs to start in terminal mode.
14728 * frame.c (make_initial_frame): Initialize faces in all cases, not
14729 only when CANNOT_DUMP is defined.
14730 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
14732 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14734 * dispnew.c (add_window_display_history): Use const for the string
14735 pointer. Remove declaration, not needed.
14737 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
14739 Use 'inline', not 'INLINE'.
14740 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
14741 * alloc.c, fontset.c (INLINE): Remove.
14742 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
14743 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
14744 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
14745 * gmalloc.c (register_heapinfo): Use inline unconditionally.
14746 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
14748 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14750 Make it possible to run ./temacs.
14752 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
14753 syms_of_callproc does the same thing. Remove test for
14754 "initialized", do it in the caller.
14755 * emacs.c (main): Avoid calling set_initial_environment when dumping.
14757 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
14759 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
14760 (read_minibuf): Use get_minibuffer.
14761 (syms_of_minibuf): Use DEFSYM.
14762 (Qmetadata): New var.
14763 * data.c (Qbuffer): Don't make it static.
14764 (syms_of_data): Use DEFSYM.
14766 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
14768 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
14769 (CCL_CODE_MIN): New macro.
14771 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
14773 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
14775 * eval.c (Qdebug): Now static.
14776 * lisp.h (Qdebug): Remove decl. This reverts a part of the
14777 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
14778 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
14780 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14782 * image.c: Various fixes to ImageMagick code comments.
14783 (Fimagemagick_types): Doc fix.
14785 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
14787 Minor fixes prompted by GCC 4.6.0 warnings.
14789 * xselect.c (converted_selections, conversion_fail_tag): Now static.
14791 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
14792 (x_clipboard_manager_save_all): Move extern decl to ...
14793 * xterm.h: ... here, so that it can be checked for consistency.
14795 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14797 * xselect.c (x_clipboard_manager_save_frame)
14798 (x_clipboard_manager_save_all): New functions.
14799 (Fx_clipboard_manager_save): Lisp function deleted.
14801 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
14802 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
14804 * xterm.h: Update prototype.
14806 2011-05-28 William Xu <william.xwl@gmail.com>
14808 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
14809 exiting (Bug#8239).
14811 2011-05-28 Jim Meyering <meyering@redhat.com>
14813 Avoid a sign-extension bug in crypto_hash_function.
14814 * fns.c (to_uchar): Define.
14815 (crypto_hash_function): Use it to convert some newly-signed
14816 variables to unsigned, to avoid sign-extension bugs. For example,
14817 without this change, (md5 "truc") would evaluate to
14818 45723a2aff78ff4fff7fff1114760e62 rather than the expected
14819 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
14820 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
14822 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14824 Integer overflow fixes.
14826 * dbusbind.c: Serial number integer overflow fixes.
14827 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
14828 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
14829 to hold a serial number that is too large for a fixnum.
14830 (Fdbus_method_return_internal, Fdbus_method_error_internal):
14831 Check for serial numbers out of range. Decode any serial number
14832 that was so large that it became a float. (Bug#8722)
14834 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
14835 (Fdbus_call_method, Fdbus_call_method_asynchronously):
14836 Use XFASTINT rather than XUINT when numbers are nonnegative.
14837 (xd_append_arg, Fdbus_method_return_internal):
14838 (Fdbus_method_error_internal): Likewise. Also, for unsigned
14839 arguments, check that Lisp number is nonnegative, rather than
14840 silently wrapping negative numbers around. (Bug#8722)
14841 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
14844 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
14846 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
14848 ccl: Add integer overflow checks.
14849 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
14850 (IN_INT_RANGE): New macros.
14851 (ccl_driver): Use them to check for integer overflow when
14852 decoding a CCL program. Many of the new checks are whether XINT (x)
14853 fits in int; it doesn't always, on 64-bit hosts. The new version
14854 doesn't catch all possible integer overflows, but it's an
14855 improvement. (Bug#8719)
14857 * alloc.c (make_event_array): Use XINT, not XUINT.
14858 There's no need for unsigned here.
14860 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
14861 This follows up to the 2011-05-06 change that substituted uintptr_t
14862 for EMACS_INT. This case wasn't caught back then.
14864 Rework Fformat to avoid integer overflow issues.
14865 * editfns.c: Include <float.h> unconditionally, as it's everywhere
14866 now (part of C89). Include <verify.h>.
14867 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
14868 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
14869 (Fformat): Avoid the prepass trying to compute sizes; it was only
14870 approximate and thus did not catch overflow reliably. Instead, walk
14871 through the format just once, formatting and computing sizes as we go,
14872 checking for integer overflow at every step, and allocating a larger
14873 buffer as needed. Keep track separately whether the format is
14874 multibyte. Keep only the most-recently calculated precision, rather
14875 than them all. Record whether each argument has been converted to
14876 string. Use EMACS_INT, not int, for byte and char and arg counts.
14877 Support field widths and precisions larger than INT_MAX. Avoid
14878 sprintf's undefined behavior with conversion specifications such as %#d
14879 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
14880 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
14881 formatting out-of-range floating point numbers with int
14882 formats. (Bug#8668)
14884 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
14886 * data.c: Avoid integer truncation in expressions involving floats.
14887 * data.c: Include <intprops.h>.
14888 (arith_driver): When there's an integer overflow in an expression
14889 involving floating point, convert the integers to floating point
14890 so that the resulting value does not suffer from catastrophic
14891 integer truncation. For example, on a 64-bit host (* 4
14892 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
14893 Do not rely on undefined behavior after integer overflow.
14895 merge count_size_as_multibyte, parse_str_to_multibyte
14896 * character.c, character.h (count_size_as_multibyte):
14897 Rename from parse_str_to_multibyte; all uses changed.
14898 Check for integer overflow.
14899 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
14900 since it's now a duplicate of the other. This is more of
14901 a character than a buffer op, so better that it's in character.c.
14902 * fns.c, print.c: Adjust to above changes.
14904 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
14906 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
14908 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14910 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14911 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
14912 (x_clipboard_manager_save): Now static.
14913 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
14915 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14916 (crypto_hash_function): Now static.
14917 Fix pointer signedness problems. Avoid unnecessary initializations.
14919 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
14921 * termhooks.h (Vselection_alist): Make it terminal-local.
14923 * terminal.c (create_terminal): Initialize it.
14925 * xselect.c: Support for clipboard managers.
14926 (Vselection_alist): Move to termhooks.h as terminal-local var.
14927 (LOCAL_SELECTION): New macro.
14928 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
14929 (symbol_to_x_atom): Remove gratuitous arg.
14930 (x_handle_selection_request, lisp_data_to_selection_data)
14931 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
14932 (x_own_selection, x_get_local_selection, x_convert_selection):
14933 New arg, specifying work frame. Use terminal-local Vselection_alist.
14934 (some_frame_on_display): Delete unused function.
14935 (Fx_own_selection_internal, Fx_get_selection_internal)
14936 (Fx_disown_selection_internal, Fx_selection_owner_p)
14937 (Fx_selection_exists_p): New optional frame arg.
14938 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
14939 (x_handle_selection_clear): Don't treat other terminals with the
14940 same keyboard specially. Use the terminal-local Vselection_alist.
14941 (x_clear_frame_selections): Use Frun_hook_with_args.
14943 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
14945 * xterm.h: Add support for those atoms.
14947 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
14949 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
14950 (converted_selections, conversion_fail_tag): New global variables.
14951 (x_selection_request_lisp_error): Free the above.
14952 (x_get_local_selection): Remove unnecessary code.
14953 (x_reply_selection_request): Args changed; handle arbitrary array
14954 of converted selections stored in converted_selections.
14955 Separate the XChangeProperty and SelectionNotify steps.
14956 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
14957 (x_convert_selection): New function.
14958 (x_handle_selection_event): Simplify.
14959 (x_get_foreign_selection): Don't ignore incoming requests while
14960 waiting for an answer; this will fail when we implement
14961 SAVE_TARGETS, and seems unnecessary anyway.
14962 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
14963 (Vx_sent_selection_functions): Doc fix.
14965 2011-05-26 Leo Liu <sdl.web@gmail.com>
14967 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
14969 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14971 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
14973 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
14974 for fringe update if it has periodic bitmap.
14975 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
14976 and fringe_bitmap_periodic_p.
14978 * fringe.c (get_fringe_bitmap_data): New function.
14979 (draw_fringe_bitmap_1, update_window_fringes): Use it.
14980 (update_window_fringes): Record periodicity of fringe bitmap in glyph
14981 row. Mark glyph row for fringe update if periodicity changed.
14983 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
14984 for fringe update unless it has periodic bitmap.
14986 2011-05-25 Kenichi Handa <handa@m17n.org>
14988 * xdisp.c (get_next_display_element): Set correct it->face_id for
14989 a static composition.
14991 2011-05-24 Leo Liu <sdl.web@gmail.com>
14994 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
14996 * fns.c (crypto_hash_function, Fsha1): New function.
14997 (Fmd5): Use crypto_hash_function.
14998 (syms_of_fns): Add Ssha1.
15000 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
15002 * gnutls.c: Remove unused macros.
15003 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
15004 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
15005 Remove macros that are defined and never used.
15006 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
15008 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
15010 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
15011 (Fx_get_selection_internal): Minor cleanup.
15012 (Fx_own_selection_internal): Rename arguments for consistency with
15015 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
15017 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
15019 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
15021 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
15023 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15025 * dispnew.c (scrolling_window): Don't exclude the case that the
15026 last enabled row in the desired matrix touches the bottom boundary.
15028 2011-05-21 Glenn Morris <rgm@gnu.org>
15030 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
15031 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
15032 and add some more files.
15034 2011-05-20 Eli Zaretskii <eliz@gnu.org>
15036 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
15037 report_file_error introduced by the change from 2011-05-07.
15039 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
15041 * systime.h (Time): Define only if emacs is defined.
15042 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
15043 where the include path doesn't have X11/X.h by default. See
15044 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
15046 2011-05-20 Kenichi Handa <handa@m17n.org>
15048 * composite.c (find_automatic_composition): Fix previous change.
15050 2011-05-20 Glenn Morris <rgm@gnu.org>
15052 * lisp.mk: New file, split from Makefile.in.
15053 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
15054 (shortlisp): Remove.
15055 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
15057 2011-05-19 Glenn Morris <rgm@gnu.org>
15059 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
15060 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
15061 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
15062 (lisp): Set the order to that of loadup.el.
15063 (shortlisp): Make it a copy of $lisp.
15064 (SOME_MACHINE_LISP): Remove.
15065 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
15066 Use just $shortlisp, not $SOME_MACHINE_LISP too.
15068 2011-05-18 Kenichi Handa <handa@m17n.org>
15070 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
15071 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
15072 (find_automatic_composition): Mostly rewrite for efficiency.
15074 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
15076 * makefile.w32-in: Update dependencies.
15078 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
15080 * menu.c: Include limits.h (fixes the MS-Windows build broken by
15081 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
15083 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
15085 Fix some integer overflow issues, such as string length overflow.
15087 * insdel.c (count_size_as_multibyte): Check for string overflow.
15089 * character.c (lisp_string_width): Check for string overflow.
15090 Use EMACS_INT, not int, for string indexes and lengths; in
15091 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
15092 the resulting string length overflows an EMACS_INT; instead,
15093 report a string overflow if no precision given. When checking for
15094 precision exhaustion, use a check that cannot possibly have
15095 integer overflow. (Bug#8675)
15096 * character.h (lisp_string_width): Adjust to new signature.
15098 * alloc.c (string_overflow): New function.
15099 (Fmake_string): Use it. This doesn't change behavior, but saves
15100 a few bytes and will simplify future changes.
15101 * character.c (string_escape_byte8): Likewise.
15102 * lisp.h (string_overflow): New decl.
15104 Fixups, following up to the user-interface timestamp change.
15105 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
15106 for UI timestamps, instead of unsigned long.
15107 * msdos.c (mouse_get_pos): Likewise.
15108 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
15109 * w32gui.h (Time): Define by including "systime.h" rather than by
15110 declaring it ourselves. (Bug#8664)
15112 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
15113 * image.c (clear_image_cache): Likewise.
15115 * term.c (term_mouse_position): Don't assume time_t wraparound.
15117 Be more systematic about user-interface timestamps.
15118 Before, the code sometimes used 'Time', sometimes 'unsigned long',
15119 and sometimes 'EMACS_UINT', to represent these timestamps.
15120 This change causes it to use 'Time' uniformly, as that's what X uses.
15121 This makes the code easier to follow, and makes it easier to catch
15122 integer overflow bugs such as Bug#8664.
15123 * frame.c (Fmouse_position, Fmouse_pixel_position):
15124 Use Time, not unsigned long, for user-interface timestamps.
15125 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
15126 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
15127 * keyboard.h (last_event_timestamp): Likewise.
15128 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
15129 * menu.h (xmenu_show): Likewise.
15130 * term.c (term_mouse_position): Likewise.
15131 * termhooks.h (struct input_event.timestamp): Likewise.
15132 (struct terminal.mouse_position_hook): Likewise.
15133 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
15134 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
15135 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
15136 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
15137 what it was before.
15138 * menu.h, termhooks.h: Include "systime.h", for Time.
15140 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
15141 Don't assume that the difference between two unsigned long values
15142 can fit into an integer. At this point, we know button_down_time
15143 <= event->timestamp, so the difference must be nonnegative, so
15144 there's no need to cast the result if double-click-time is
15145 nonnegative, as it should be; check that it's nonnegative, just in
15146 case. This bug is triggered when events are more than 2**31 ms
15147 apart (about 25 days). (Bug#8664)
15149 * xselect.c (last_event_timestamp): Remove duplicate decl.
15150 (x_own_selection): Remove needless cast to unsigned long.
15152 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
15153 that always fit in int. Use a sentinel instead of a counter, to
15154 avoid a temp and to allay GCC's concerns about possible int overflow.
15155 * frame.h (struct frame): Use int for menu_bar_items_used
15156 instead of EMACS_INT, since it always fits in int.
15158 * menu.c (grow_menu_items): Check for int overflow.
15160 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
15162 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
15163 Before, the code was not consistent. These values cannot exceed
15164 2**31 - 1 so there's no need to make them unsigned.
15165 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
15166 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
15167 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
15169 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
15171 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
15172 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
15173 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
15174 presumably because the widths might not match.
15176 * window.c (size_window): Avoid needless test at loop start.
15178 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
15180 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
15182 2011-05-12 Drew Adams <drew.adams@oracle.com>
15184 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
15186 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15188 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
15189 `width' to `bar_area_x' and `bar_area_width', respectively.
15190 (x_scroll_run): Take account of fringe background extension.
15192 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
15193 Rename local vars `left' and `width' to `bar_area_x' and
15194 `bar_area_width', respectively.
15195 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
15196 background extension.
15198 2011-05-10 Jim Meyering <meyering@redhat.com>
15200 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
15202 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
15204 * image.c (Finit_image_library): Return t for built-in image types,
15205 like pbm and xbm. (Bug#8640)
15207 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
15209 * w32menu.c (set_frame_menubar): Fix submenu allocation.
15211 2011-05-07 Eli Zaretskii <eliz@gnu.org>
15213 * w32console.c (Fset_screen_color): Doc fix.
15214 (Fget_screen_color): New function.
15215 (syms_of_ntterm): Defsubr it.
15217 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
15218 unlink the temporary file if Fcall_process didn't create it in the
15220 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
15221 child process will be redirected to a file specified with `:file'.
15222 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
15223 cue to call_process_cleanup not to close that handle.
15225 2011-05-07 Ben Key <bkey76@gmail.com>
15227 * makefile.w32-in: The bootstrap-temacs rule now makes use of
15228 one of two shell specific rules, either bootstrap-temacs-CMD or
15229 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
15230 to the previous implementation of the bootstrap-temacs rule.
15231 The bootstrap-temacs-CMD rule is similar to the previous
15232 implementation of the bootstrap-temacs rule except that it
15233 makes use of the ESC_CFLAGS variable instead of the CFLAGS
15236 These changes, along with some changes to nt/configure.bat,
15237 nt/gmake.defs, and nt/nmake.defs, are required to extend my
15238 earlier fix to add support for --cflags and --ldflags options
15239 that include quotes so that it works whether make uses cmd or
15242 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
15244 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
15245 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
15247 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
15248 a string. Handle both cases.
15249 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
15250 (Fdbus_register_method): Use Qinvalid_function.
15252 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
15254 * makefile.w32-in: Update dependencies.
15255 (LISP_H): Add inttypes.h and stdin.h.
15256 (PROCESS_H): Add unistd.h.
15258 2011-05-06 Eli Zaretskii <eliz@gnu.org>
15260 * lread.c: Include limits.h (fixes the MS-Windows build broken by
15261 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
15263 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
15265 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
15267 * term.c (vfatal): Remove stray call to va_end.
15268 It's not needed and the C Standard doesn't allow it here anyway.
15270 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
15271 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
15273 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
15276 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
15278 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15280 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
15282 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
15284 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
15286 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
15287 * charset.c (Fdefine_charset_internal): Don't initialize
15288 charset.code_space[15]. The value was garbage, on hosts with
15289 32-bit int (Bug#8600).
15291 * lread.c (read_integer): Be more consistent with string-to-number.
15292 Use string_to_number to do the actual conversion; this avoids
15293 rounding errors and fixes some other screwups. Without this fix,
15294 for example, #x1fffffffffffffff was misread as -2305843009213693952.
15295 (digit_to_number): Move earlier, for benefit of read_integer.
15296 Return -1 if the digit is out of range for the base, -2 if it is
15297 not a digit in any supported base. (Bug#8602)
15299 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
15301 * dispnew.c (scrolling_window): Return 1 if we scrolled,
15302 to match comment at start of function. This also removes a
15303 GCC warning about overflow in a 32+64-bit port.
15305 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
15307 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
15308 Reported by Stefan Monnier in
15309 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
15310 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
15311 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
15313 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
15314 (EMACS_UINTPTR): Likewise, with uintptr_t.
15316 * lisp.h: Prefer 64-bit EMACS_INT if available.
15317 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
15318 on 32-bit hosts that have 64-bit int, so that they can access
15320 However, temporarily disable this change unless the temporary
15321 symbol WIDE_EMACS_INT is defined.
15323 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
15325 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
15326 This removes an assumption that EMACS_INT and long are the same
15327 width as pointers. The assumption is true for Emacs porting targets
15328 now, but we want to make other targets possible.
15329 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
15330 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
15331 In the rest of the code, change types of integers that hold casted
15332 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
15333 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
15334 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
15335 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
15336 No need to cast type when ORing.
15337 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
15338 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
15339 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
15340 assume EMACS_INT is the same width as char *.
15341 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
15342 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
15343 Remove no-longer-needed casts.
15344 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
15345 (xg_tool_bar_help_callback, xg_make_tool_item):
15346 Use EMACS_INTPTR to hold an integer
15347 that will be cast to void *; this can avoid a GCC warning
15348 if EMACS_INT is not the same width as void *.
15349 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
15350 * xdisp.c (display_echo_area_1, resize_mini_window_1):
15351 (current_message_1, set_message_1):
15352 Use a local to convert to proper width without a cast.
15353 * xmenu.c (dialog_selection_callback): Likewise.
15355 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
15356 Also, don't assume VALBITS / RAND_BITS is less than 5,
15357 and don't rely on undefined behavior when shifting a 1 left into
15359 * lisp.h (get_random): Change signature to match.
15361 * lread.c (hash_string): Use size_t, not int, for hash computation.
15362 Normally we prefer signed values; but hashing is special, because
15363 it's better to use unsigned division on hash table sizes so that
15364 the remainder is nonnegative. Also, size_t is the natural width
15365 for hashing into memory. The previous code used 'int', which doesn't
15366 retain enough info to hash well into very large tables.
15367 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
15369 * dbusbind.c: Don't possibly lose pointer info when converting.
15370 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
15371 Use XPNTR rather than XHASH, so that the high-order bits of
15372 the pointer aren't lost when converting through void *.
15374 * eval.c (Fautoload): Don't double-shift a pointer.
15376 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
15378 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
15380 * gnutls.c (DEF_GNUTLS_FN):
15381 * image.c (DEF_IMGLIB_FN): Make function pointers static.
15383 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
15385 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
15388 2011-05-05 Eli Zaretskii <eliz@gnu.org>
15390 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
15391 New version that can reserve upto 2GB of heap space.
15393 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
15395 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
15397 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
15399 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
15400 `gnutls_certificate_set_x509_key_file'.
15402 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
15404 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
15405 Update dependencies.
15407 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15409 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
15410 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
15411 Remove unused parameter `fildes'.
15412 * process.c (read_process_output, send_process): Don't pass it.
15414 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15416 Fix previous change: the library cache is defined in w32.c.
15417 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
15418 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
15420 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15422 Implement dynamic loading of GnuTLS on Windows.
15424 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
15425 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
15426 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
15429 * gnutls.c (Qgnutls_dll): Define.
15430 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
15431 (gnutls_*): Declare function pointers.
15432 (init_gnutls_functions): New function to initialize function pointers.
15433 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
15434 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
15435 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
15436 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
15437 (emacs_gnutls_write, emacs_gnutls_read)
15438 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
15439 (Fgnutls_available_p): New function.
15440 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
15441 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
15442 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
15444 * image.c: Include w32.h.
15445 (Vimage_type_cache): Delete.
15446 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
15447 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
15448 (w32_delayed_load): Move to w32.c.
15450 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
15452 * w32.c (QCloaded_from, Vlibrary_cache): Define.
15453 (w32_delayed_load): Move from image.c. When loading a library, record
15454 its filename in the :loaded-from property of the library id.
15455 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
15456 Initialize and staticpro them.
15457 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
15459 * process.c: Include lisp.h before w32.h, not after.
15460 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
15461 instead of gnutls_record_check_pending.
15463 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
15465 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
15467 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
15468 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
15471 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
15473 * xterm.c (x_set_frame_alpha): Do not set property on anything
15474 else than FRAME_X_OUTER_WINDOW (Bug#8608).

15494 * callproc.c: Indentation fixup.
15496 * sysdep.c (wait_for_termination_1): Make static.
15497 (wait_for_termination, interruptible_wait_for_termination):
15498 Move after wait_for_termination_1.
15500 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
15502 * sysdep.c (interruptible_wait_for_termination): New function
15503 which is like wait_for_termination, but allows keyboard
15506 * callproc.c (Fcall_process): Add (:file "file") as an option for
15508 (Fcall_process_region): Ditto.
15510 2011-04-30 Eli Zaretskii <eliz@gnu.org>
15512 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
15513 rather than `XVECTOR (FOO)->size'.
15515 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
15516 inttypes.h, as a gnulib replacement is used if it not available in
15519 2011-04-21 Eli Zaretskii <eliz@gnu.org>
15521 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
15522 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
15523 of MOST_POSITIVE_FIXNUM. (Bug#8528)
15525 * coding.c (coding_alloc_by_realloc): Error out if destination
15526 will grow beyond MOST_POSITIVE_FIXNUM.
15527 (decode_coding_emacs_mule): Abort if there isn't enough place in
15528 charbuf for the composition carryover bytes. Reserve an extra

15538 %llo or %llx format is passed. (Bug#8545)
15540 * window.c (window_scroll_line_based): Use a marker instead of
15541 simple variables to record original value of point. (Bug#7952)
15543 * doprnt.c (doprnt): Fix the case where a multibyte sequence
15544 produced by %s or %c overflows available buffer space. (Bug#8545)
15546 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
15548 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
15549 (SIZE_MAX): Move defn after all includes, as they might #define it.
15551 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15553 * w32.c (init_environment): Warn about defaulting HOME to C:\.

15573 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15575 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
15577 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
15579 * makefile.w32-in: Update dependencies.
15581 2011-04-27 Eli Zaretskii <eliz@gnu.org>
15583 Improve `doprnt' and its usage. (Bug#8545)
15584 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
15585 `format_end'. Remove support for %l as a conversion specifier.
15586 Don't use xrealloc. Improve diagnostics when the %l size modifier
15587 is used. Update the commentary.
15589 * eval.c (verror): Simplify calculation of size_t.
15591 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
15594 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
15596 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
15599 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15601 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
15602 This makes this file independent of the recent pseudovector change.
15604 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
15606 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
15608 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
15609 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
15610 Remove unused local.
15611 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
15613 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
15614 GCC 4.6.0 optimizes based on type-based alias analysis.
15615 For example, if b is of type struct buffer * and v of type struct
15616 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
15617 != &v->size, and therefore "v->size = 1; b->size = 2; return
15618 v->size;" must therefore return 1. This assumption is incorrect
15619 for Emacs, since it type-puns struct Lisp_Vector * with many other
15620 types. To fix this problem, this patch adds a new type struct
15621 vectorlike_header that documents the constraints on layout of vectors
15622 and pseudovectors, and helps optimizing compilers not get fooled
15623 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
15624 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
15625 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
15627 (XSETPVECTYPE): Rewrite in terms of new macro.
15628 (XSETPVECTYPESIZE): New macro, specifying both type and size.
15629 This is a bit clearer, and further avoids the possibility of
15630 undesirable aliasing.
15631 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
15632 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
15633 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
15634 since Lisp_Subr is a special case (no "next" field).
15635 (ASIZE): Now uses header.size rather than size.
15636 All previous uses of XVECTOR (foo)->size replaced to use this macro,
15637 to avoid the hassle of writing XVECTOR (foo)->header.size.
15638 (struct vectorlike_header): New type.
15639 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
15640 object, to help avoid aliasing.
15641 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
15642 (SUBRP): Likewise, since Lisp_Subr is a special case.
15643 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
15644 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
15645 (struct Lisp_Hash_Table): Combine first two members into a single
15646 struct vectorlike_header member. All uses of "size" and "next" members
15647 changed to be "header.size" and "header.next".
15648 * buffer.h (struct buffer): Likewise.
15649 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
15650 * frame.h (struct frame): Likewise.
15651 * process.h (struct Lisp_Process): Likewise.
15652 * termhooks.h (struct terminal): Likewise.
15653 * window.c (struct save_window_data, struct saved_window): Likewise.
15654 * window.h (struct window): Likewise.
15655 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
15656 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
15657 * buffer.c (init_buffer_once): Likewise.
15658 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
15660 * process.c (Fformat_network_address): Use local var for size,
15663 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
15665 Make the Lisp reader and string-to-float more consistent (Bug#8525)
15666 * data.c (atof): Remove decl; no longer used or needed.
15667 (digit_to_number): Move to lread.c.
15668 (Fstring_to_number): Use new string_to_number function, to be
15669 consistent with how the Lisp reader treats infinities and NaNs.
15670 Do not assume that floating-point numbers represent EMACS_INT
15671 without losing information; this is not true on most 64-bit hosts.
15672 Avoid double-rounding errors, by insisting on integers when
15673 parsing non-base-10 numbers, as the documentation specifies.
15674 * lisp.h (string_to_number): New decl, replacing ...
15675 (isfloat_string): Remove.
15676 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
15677 (read1): Do not accept +. and -. as integers; this
15678 appears to have been a coding error. Similarly, do not accept
15679 strings like +-1e0 as floating point numbers. Do not report
15680 overflow for integer overflows unless the base is not 10 which
15681 means we have no simple and reliable way to continue.
15682 Break out the floating-point parsing into a new
15683 function string_to_number, so that Fstring_to_number parses
15684 floating point numbers consistently with the Lisp reader.
15685 (digit_to_number): Move here from data.c. Make it static inline.
15686 (E_CHAR, EXP_INT): Remove, replacing with ...
15687 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
15688 (string_to_number): New function, replacing isfloat_string.
15689 This function checks for valid syntax and produces the resulting
15690 Lisp float number too. Rework it so that string-to-number
15691 no longer mishandles examples like "1.0e+". Use strtoumax,
15692 so that overflow for non-base-10 numbers is reported only when
15693 there's no portable and simple way to convert to floating point.
15695 * textprop.c (set_text_properties_1): Rewrite for clarity,
15696 and to avoid GCC warning about integer overflow.
15698 * intervals.h (struct interval): Use EMACS_INT for members
15699 where EMACS_UINT might cause problems. See
15700 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
15701 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
15702 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
15704 (offset_intervals): Tell GCC not to worry about length overflow
15705 when negating a negative length.
15707 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
15708 (overrun_check_free): Likewise.
15710 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
15711 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
15714 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15715 (gnutls_make_error): Rename local to avoid shadowing.
15716 (gnutls_emacs_global_deinit): ifdef out; not used.
15717 (Fgnutls_boot): Use const for pointer to readonly storage.
15718 Comment out unused local. Fix pointer signedness problems.
15720 * lread.c (openp): Don't stuff size_t into an 'int'.
15721 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
15722 about possible signed overflow.
15724 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15725 (GDK_KEY_g): Don't define if already defined.
15726 (xg_prepare_tooltip): Avoid pointer signedness problem.
15727 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
15729 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
15730 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
15732 * xfns.c (Fx_window_property): Simplify a bit,
15733 to make a bit faster and to avoid GCC 4.6.0 warning.
15734 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
15736 * fns.c (internal_equal): Don't assume size_t fits in int.
15738 * alloc.c (compact_small_strings): Tighten assertion a little.
15740 Replace pEd with more-general pI, and fix some printf arg casts.
15741 * lisp.h (pI): New macro, generalizing old pEd macro to other
15742 conversion specifiers. For example, use "...%"pI"d..." rather
15743 than "...%"pEd"...".
15744 (pEd): Remove. All uses replaced with similar uses of pI.
15745 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
15746 * alloc.c (check_pure_size): Don't overflow by converting size to int.
15747 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
15748 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
15749 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
15750 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
15751 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
15753 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
15754 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
15755 * print.c (safe_debug_print, print_object): Likewise.
15756 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
15758 Use pI instead of if-then-else-abort. Use %p to avoid casts,
15759 avoiding the 0 flag, which is not portable.
15760 * process.c (Fmake_network_process): Use pI to avoid cast.
15761 * region-cache.c (pp_cache): Likewise.
15762 * xdisp.c (decode_mode_spec): Likewise.
15763 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
15764 behavior on 64-bit hosts with printf arg.
15765 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
15766 (x_stop_queuing_selection_requests): Likewise.
15767 (x_get_window_property): Don't truncate byte count to an 'int'
15770 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
15771 here, since it parses constructs like leading '-' and spaces,
15772 which are not wanted; and it overflows with large numbers.
15773 Instead, simply match F[0-9]+, which is what is wanted anyway.
15775 * alloc.c: Remove unportable assumptions about struct layout.
15776 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
15777 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
15778 (allocate_vectorlike, make_pure_vector): Use the new macros,
15779 plus offsetof, to remove unportable assumptions about struct layout.
15780 These assumptions hold on all porting targets that I know of, but
15781 they are not guaranteed, they're easy to remove, and removing them
15782 makes further changes easier.
15784 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
15785 This doesn't fix a bug but makes the code clearer.
15786 (string_overrun_cookie): Now const. Use initializers that
15787 don't formally overflow signed char, to avoid warnings.
15788 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
15789 can cause Emacs to crash when string overrun checking is enabled.
15790 (allocate_buffer): Don't assume sizeof (struct buffer) is a
15791 multiple of sizeof (EMACS_INT); it need not be, if
15792 alignof(EMACS_INT) < sizeof (EMACS_INT).
15793 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
15795 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

15802 supposed to be handshaking. (Bug#8556)
15803 Reported by Paul Eggert <eggert@cs.ucla.edu>.
15805 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

15810 (handle_user_signal): Break into debugger when debug-on-event
15811 matches the current signal symbol.
15813 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
15815 * alloc.c (check_sblock, check_string_bytes)
15816 (check_string_free_list): Convert to standard C.
15818 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
15820 * w32.c (emacs_gnutls_push): Fix typo.
15822 2011-04-25 Eli Zaretskii <eliz@gnu.org>
15824 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
15825 "cast to pointer from integer of different size".
15827 Improve doprnt and its use in verror. (Bug#8545)
15828 * doprnt.c (doprnt): Document the set of format control sequences
15829 supported by the function. Use SAFE_ALLOCA instead of always
15832 * eval.c (verror): Don't limit the buffer size at size_max-1, that
15833 is one byte too soon. Don't use xrealloc; instead xfree and
15836 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
15838 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
15841 * gnutls.c: Renamed global_initialized to
15842 gnutls_global_initialized. Added internals for the
15843 :verify-hostname-error, :verify-error, and :verify-flags
15844 parameters of `gnutls-boot' and documented those parameters in the
15845 docstring. Start callback support.
15846 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
15847 unless a fatal error occurred. Call gnutls_alert_send_appropriate
15848 on error. Return error code.
15849 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
15850 (emacs_gnutls_read): Likewise.
15851 (Fgnutls_boot): Return handshake error code.
15852 (emacs_gnutls_handle_error): New function.
15853 (wsaerror_to_errno): Likewise.

15864 buffered some data internally if no FDs are set for TLS
15867 * makefile.w32-in (OBJ2): Add gnutls.$(O).

15915 <char-direction-table>: Deleted.
15917 2011-04-23 Eli Zaretskii <eliz@gnu.org>
15919 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
15920 * doprnt.c: Include limits.h.
15921 (SIZE_MAX): New macro.
15922 (doprnt): Return a size_t value. 2nd arg is now size_t.
15923 Many local variables are now size_t instead of int or unsigned.
15924 Improve overflow protection. Support `l' modifier for integer
15925 conversions. Support %l conversion. Don't assume an EMACS_INT
15926 argument for integer conversions and for %c.
15928 * lisp.h (doprnt): Restore prototype.
15930 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
15931 $(SRC)/character.h.
15933 * Makefile.in (base_obj): Add back doprnt.o.
15935 * deps.mk (doprnt.o): Add back prerequisites.
15936 (callint.o): Depend on character.h.
15938 * eval.c (internal_lisp_condition_case): Include the handler
15939 representation in the error message.
15940 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
15941 when breaking from the loop.
15943 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
15945 * callint.c (Fcall_interactively): When displaying error message
15946 about invalid control letter, pass the character's codepoint, not
15947 a pointer to its multibyte form. Improve display of the character
15948 in octal and display also its hex code.
15950 * character.c (char_string): Use %x to display the (unsigned)
15951 codepoint of an invalid character, to avoid displaying a bogus
15954 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
15955 `error', not SYMBOL_NAME itself.
15957 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
15958 character arguments to `error'.
15960 * charset.c (check_iso_charset_parameter): Fix incorrect argument
15961 to `error' in error message about FINAL_CHAR argument. Make sure
15962 FINAL_CHAR is a character, and use %c when it is passed as
15963 argument to `error'.

16027 Define only if needed.
16029 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
16030 by pacifying GCC about it. Maybe it's time to retire it?
16031 * xfaces.c (USG, __TIMEVAL__): Likewise.
16033 * dispextern.h (struct redisplay_interface): Rename param
16034 to avoid shadowing.
16035 * termhooks.h (struct terminal): Likewise.
16036 * xterm.c (xembed_send_message): Likewise.
16038 * insdel.c (make_gap_smaller): Define only if

16498 * ccl.h (check_ccl_update, Vccl_program_table): Remove decls.
16499 * ccl.c (Vccl_program_table): Now static.
16500 (check_ccl_update): Remove; unused.
16502 * category.c (SET_CATEGORY_SET, set_category_set): Move here.
16503 * category.h: ... from here.
16504 * category.c (check_category_table, set_category_set): Now static.
16506 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
16507 * lisp.h: Remove these decls.
16509 * buffer.c (buffer_count): Remove unused var.
16511 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
16512 so that it's not optimized away.
16513 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
16514 * dispextern.h (bidi_dump_cached_states): Remove, since it's
16515 exported only to the debugger.
16517 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
16518 * atimer.h (run_all_atimers): Remove; not exported.
16520 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
16521 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
16522 was inaccessible from Lisp.
16523 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
16524 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
16526 alloc.c: Import and export fewer symbols, and remove unused items.
16527 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
16529 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
16530 it's not optimized away by whole-program optimization.
16531 (message_enable_multibyte, free_misc): Remove.
16532 (catchlist, handlerlist, mark_backtrace):
16533 Declare only if BYTE_MARK_STACK.
16534 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
16535 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
16536 (message_enable_multibyte): Remove decl.
16537 (free_misc, interval_free_list, float_block, float_block_index):
16538 (n_float_blocks, float_free_list, cons_block, cons_block_index):
16539 (cons_free_list, last_marked_index):
16541 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
16542 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
16543 (mark_backtrace): Define only if BYTE_MARK_STACK.
16544 * xdisp.c (message_enable_multibyte): Now static.
16546 Declare Lisp_Object Q* variables to be 'static' if not exported.
16547 This makes it easier for human readers (and static analyzers)
16548 to see whether these variables are used from other modules.
16549 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
16550 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
16551 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

16554 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
16555 * xmenu.c, xselect.c:
16556 Declare Q* vars static if they are not used in other modules.
16557 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
16558 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
16559 Remove decls of unexported vars.
16560 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
16562 * lisp.h (DEFINE_FUNC): Make sname 'static'.
16564 Make Emacs functions such as Fatom 'static' by default.
16565 This makes it easier for human readers (and static analyzers)
16566 to see whether these functions can be called from other modules.
16567 DEFUN now defines a static function. To make the function external
16568 so that it can be used in other C modules, use the new macro DEFUE.
16569 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
16570 (Finit_image_library):
16571 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
16572 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
16573 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
16574 Remove decls, since these functions are now static.
16575 (Funintern, Fget_internal_run_time): New decls, since these functions
16576 were already external.
16578 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
16579 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

16585 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
16586 Mark functions with DEFUE instead of DEFUN,
16587 if they are used in other modules.
16588 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
16589 decls for now-static functions.
16590 * buffer.h (Fdelete_overlay): Remove decl.
16591 * callproc.c (Fgetenv_internal): Mark as internal.
16592 * composite.c (Fremove_list_of_text_properties): Remove decl.

16596 * doc.c (Fdocumntation_property): New forward static decl.
16597 * eval.c (Ffetch_bytecode): New forward static decl.
16598 (Funintern): Remove extern decl; now in .h file where it belongs.
16599 * fileio.c (Fmake_symbolic_link): New forward static decl.
16600 * image.c (Finit_image_library): New forward static decl.
16601 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
16602 * intervals.h (Fprevious_property_change):
16603 (Fremove_list_of_text_properties): Remove decls.
16604 * keyboard.c (Fthis_command_keys): Remove decl.
16605 (Fcommand_execute): New forward static decl.
16606 * keymap.c (Flookup_key): New forward static decl.
16607 (Fcopy_keymap): Now static.
16608 * keymap.h (Flookup_key): Remove decl.
16609 * process.c (Fget_process): New forward static decl.
16610 (Fprocess_datagram_address): Mark as internal.

16621 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
16623 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
16626 2011-04-13 Eli Zaretskii <eliz@gnu.org>
16628 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
16629 when at ZV. (Bug#8487)
16631 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
16633 * charset.c (Fclear_charset_maps): Use xfree instead of free.
16635 * keyboard.c (parse_tool_bar_item): Likewise.
16636 * sound.c (sound_cleanup, alsa_close): Likewise.
16637 * termcap.c (tgetent): Likewise.
16638 * xfns.c (x_default_font_parameter): Likewise.
16639 * xsettings.c (read_and_apply_settings): Likewise.
16641 * alloc.c (overrun_check_malloc, overrun_check_realloc)
16642 (overrun_check_free): Protoize.
16644 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
16646 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
16647 since callers should never pass a negative size.
16648 Change the signature to match that of plain 'read' and 'write'; see
16649 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
16650 * lisp.h: Update prototypes of emacs_write and emacs_read.
16652 2011-04-11 Eli Zaretskii <eliz@gnu.org>
16654 * xdisp.c (redisplay_window): Don't try to determine the character
16655 position of the scroll margin if the window start point w->startp
16656 is outside the buffer's accessible region. (Bug#8468)
16658 2011-04-10 Eli Zaretskii <eliz@gnu.org>
16660 Fix write-region and its subroutines for buffers > 2GB.
16661 * fileio.c (a_write, e_write): Modify declaration of arguments and
16662 local variables to support buffers larger than 2GB.
16663 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
16665 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
16666 argument, local variables, and return value.
16668 * lisp.h: Update prototypes of emacs_write and emacs_read.
16670 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
16672 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
16674 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
16676 Fix more problems found by GCC 4.6.0's static checks.
16678 * xdisp.c (vmessage): Use a better test for character truncation.
16680 * charset.c (load_charset_map): <, not <=, for optimization,
16681 and to avoid potential problems with integer overflow.
16682 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
16683 * casetab.c (set_identity, shuffle): Likewise.
16684 * editfns.c (Fformat): Likewise.
16685 * syntax.c (skip_chars): Likewise.
16687 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
16688 This also lets GCC 4.6.0 generate slightly better loop code.
16690 * callint.c (Fcall_interactively): <, not <=, for optimization.
16691 (Fcall_interactively): Count the number of arguments produced,
16692 not the number of arguments given. This is simpler and lets GCC
16693 4.6.0 generate slightly better code.
16695 * ftfont.c: Distingish more carefully between FcChar8 and char.
16696 The previous code passed unsigned char * to a functions like
16697 strlen and xstrcasecmp that expect char *, which does not
16698 conform to the C standard.
16699 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
16700 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
16701 char * when the C standard requires it.
16703 * keyboard.c (read_char): Remove unused var.
16705 * eval.c: Port to Windows vsnprintf (Bug#8435).
16706 Include <limits.h>.
16707 (SIZE_MAX): Define if the headers do not.
16708 (verror): Do not give up if vsnprintf returns a negative count.
16709 Instead, grow the buffer. This ports to Windows vsnprintf, which
16710 does not conform to C99. Problem reported by Eli Zaretskii.
16711 Also, simplify the allocation scheme, by avoiding the need for
16712 calling realloc, and removing the ALLOCATED variable.
16714 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
16716 Remove invocations of doprnt, as Emacs now uses vsnprintf.
16717 But keep the doprint source code for now, as we might revamp it
16718 and use it again (Bug#8435).
16719 * lisp.h (doprnt): Remove.
16720 * Makefile.in (base_obj): Remove doprnt.o.
16721 * deps.mk (doprnt.o): Remove.
16723 error: Print 32- and 64-bit integers portably (Bug#8435).
16724 Without this change, on typical 64-bit hosts error ("...%d...", N)
16725 was used to print both 32- and 64-bit integers N, which relied on
16726 undefined behavior.
16727 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
16728 * lisp.h (error, verror): Mark as printf-like functions.
16729 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
16730 Report overflow in size calculations when allocating printf buffer.
16731 Do not truncate output string at its first null byte.
16732 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
16733 Truncate the output at a character boundary, since vsnprintf does not
16735 * charset.c (check_iso_charset_parameter): Convert internal
16736 character to string before calling 'error', since %c now has the
16738 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
16739 overflow when computing char to be passed to 'error'. Do not
16740 pass Lisp_Object to 'error'; pass the integer instead.
16741 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
16742 formatted with plain %d.
16744 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
16746 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
16748 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
16750 * xterm.c (x_catch_errors): Remove duplicate declaration.
16752 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
16754 * xdisp.c, lisp.h (message_nolog): Remove; unused.
16756 2011-04-10 Jim Meyering <meyering@redhat.com>
16758 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
16759 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
16760 return ssize_t not "int", and use size_t as the buffer length.
16761 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
16762 * gnutls.h: Update declarations.
16763 * process.c (read_process_output): Use ssize_t, to match.
16764 (send_process): Likewise.
16766 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16768 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
16770 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16772 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
16773 Use unsigned char, to match FcChar8 type definition.
16775 * xterm.c (handle_one_xevent):
16776 * xmenu.c (create_and_show_popup_menu):
16777 * xselect.c (x_decline_selection_request)
16778 (x_reply_selection_request): Avoid type-punned deref of X events.
16780 2011-04-09 Eli Zaretskii <eliz@gnu.org>
16782 Fix some uses of `int' instead of EMACS_INT.
16783 * search.c (string_match_1, fast_string_match)
16784 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
16785 (scan_buffer, find_next_newline_no_quit)
16786 (find_before_next_newline, search_command, Freplace_match)
16787 (Fmatch_data): Make some `int' variables be EMACS_INT.
16789 * xdisp.c (display_count_lines): 3rd argument and return value now
16790 EMACS_INT. All callers changed.
16791 (pint2hrstr): Last argument is now EMACS_INT.
16793 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
16794 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
16795 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
16796 (decode_coding_utf_16, decode_coding_emacs_mule)
16797 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
16798 (decode_coding_ccl, decode_coding_charset)
16799 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
16800 (decode_coding_iso_2022, decode_coding_emacs_mule)
16801 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
16802 <char_offset, last_offset>: Declare EMACS_INT.

16804 (encode_coding_emacs_mule, encode_invocation_designation)
16805 (encode_designation_at_bol, encode_coding_iso_2022)
16806 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
16807 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
16809 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
16810 (encode_invocation_designation): Last argument P_NCHARS is now
16812 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
16813 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
16815 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
16818 * ccl.c (Fccl_execute_on_string): Declare some variables
16821 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
16823 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
16825 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
16827 * process.c (Fformat_network_address): Doc fix.
16829 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
16831 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
16833 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
16835 * keyboard.c (read_char): Call Lisp function help-form-show,
16836 instead of using internal_with_output_to_temp_buffer.
16837 (Qhelp_form_show): New var.
16838 (syms_of_keyboard): Use DEFSYM macro.
16840 * print.c (internal_with_output_to_temp_buffer): Function deleted.

16844 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
16846 * process.c (Flist_processes): Remove to Lisp.
16847 (list_processes_1): Delete.
16849 2011-04-06 Eli Zaretskii <eliz@gnu.org>
16851 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
16853 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
16855 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
16857 Fix more problems found by GCC 4.6.0's static checks.
16859 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
16861 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
16863 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
16865 * xdisp.c (vmessage): Mark as a printf-like function.
16867 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
16869 * sound.c (sound_warning): Don't crash if arg contains a printf format.
16871 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
16872 printf-like functions.
16873 (tiff_load): Add casts to remove these marks before passing them
16874 to system-supplied API.
16876 * eval.c (Fsignal): Remove excess argument to 'fatal'.
16878 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
16879 This avoids several warnings with gcc -Wstrict-overflow.
16880 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
16881 directly, rather than having caller test rule sign. This avoids
16882 some unnecessary tests.
16883 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
16884 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
16885 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
16887 * xfont.c (xfont_text_extents): Remove var that was set but not used.
16888 (xfont_open): Avoid unnecessary tests.
16890 * composite.c (composition_gstring_put_cache): Use unsigned integer.

16899 by using the new macro.
16901 * textprop.c (set_text_properties_1): Change while to do-while,
16902 since the condition is always true at first.
16904 * intervals.c (graft_intervals_into_buffer): Mark var as used.
16905 (interval_deletion_adjustment): Return unsigned value.
16908 * process.c (list_processes_1, create_pty, read_process_output):

16910 (create_pty): Remove unnecessary "volatile"s.
16911 (Fnetwork_interface_info): Avoid possibility of int overflow.
16912 (read_process_output): Do adaptive read buffering even if carryover.
16913 (read_process_output): Simplify nbytes computation if buffered.

16924 * print.c (print_error_message): Avoid int overflow.
16926 * font.c (font_list_entities): Redo for clarity,
16927 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.

16942 (wordify): Omit three unnecessary tests.
16944 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

16949 * dired.c (file_name_completion): Remove var that is set but not used.
16951 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
16953 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
16954 (Finsert_file_contents): Remove unnecessary code checking fd.
16956 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
16957 Check for integer overflow on size calculations.
16959 * buffer.c (Fprevious_overlay_change): Remove var that is set
16962 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
16963 Remove vars that are set but not used.
16964 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
16965 (timer_check_2): Mark vars as initialized.
16967 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
16969 * image.c (lookup_image): Remove var that is set but not used.
16970 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
16972 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
16973 that are set but not used.
16975 * xfns.c (make_invisible_cursor): Don't return garbage
16976 if XCreateBitmapFromData fails (Bug#8410).
16978 * xselect.c (x_get_local_selection, x_handle_property_notify):
16979 Remove vars that are set but not used.
16981 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
16982 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
16984 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
16985 Remove var that is set but not used.
16986 (scroll_bar_windows_size): Now size_t, not int.
16987 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
16988 Check for overflow.
16990 * xfaces.c (realize_named_face): Remove vars that are set but not used.
16991 (map_tty_color) [!defined MSDOS]: Likewise.
16993 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
16995 * coding.c: Remove vars that are set but not used.
16996 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
16997 All callers changed.
16998 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
16999 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
17000 (decode_coding_charset): Remove vars that are set but not used.
17002 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
17003 that is set but not used.
17005 * print.c (print_object): Remove var that is set but not used.
17007 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
17008 The gnulib version avoids calling malloc in the usual case,
17009 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
17010 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
17011 * filelock.c (current_lock_owner): Likewise.
17012 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
17013 * sysdep.c: Include allocator.h, careadlinkat.h.
17014 (emacs_no_realloc_allocator): New static constant.
17015 (emacs_readlink): New function.
17016 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
17017 ../lib/careadlinkat.h.
17019 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
17021 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
17022 first non-nil return value).

17043 do not dereference NULL upon failed strdup
17044 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
17045 (ns_get_family): Likewise.
17047 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
17049 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
17051 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
17053 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
17056 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
17058 Add lexical binding.
17060 * window.c (Ftemp_output_buffer_show): New fun.
17061 (Fsave_window_excursion):
17062 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
17064 * lread.c (lisp_file_lexically_bound_p): New function.

17067 Bind Qinternal_interpreter_environment.
17068 (Feval_buffer): Bind Qlexical_binding.
17069 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
17071 (syms_of_lread): Declare `lexical-binding'.
17073 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
17075 * keyboard.c (eval_dyn): New fun.
17076 (menu_item_eval_property): Use it.
17078 * image.c (parse_image_spec): Use Ffunctionp.
17080 * fns.c (concat, mapcar1): Accept byte-code-functions.
17082 * eval.c (Fsetq): Handle lexical vars.
17083 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
17084 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
17085 (FletX, Flet): Obey lexical binding.
17086 (Fcommandp): Handle closures.
17087 (Feval): New `lexical' arg.
17088 (eval_sub): New function extracted from Feval. Use it almost
17089 everywhere where Feval was used. Look up vars in lexical env.
17091 (Ffunctionp): Move from subr.el.
17092 (Ffuncall): Handle closures.
17093 (apply_lambda): Remove `eval_flags'.
17094 (funcall_lambda): Handle closures and new byte-code-functions.
17095 (Fspecial_variable_p): New function.
17096 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
17097 but without exporting it to Lisp.
17099 * doc.c (Fdocumentation, store_function_docstring):
17100 * data.c (Finteractive_form): Handle closures.
17102 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
17105 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
17107 (exec_byte_code): New function extracted from Fbyte_code to handle new
17108 calling convention for byte-code-functions. Add new byte-codes.
17110 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
17112 * alloc.c (Fmake_symbol): Init new `declared_special' field.
17114 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
17116 * xdisp.c (redisplay_internal): Fix prototype.
17118 2011-03-31 Eli Zaretskii <eliz@gnu.org>
17120 * xdisp.c (SCROLL_LIMIT): New macro.
17121 (try_scrolling): Use it when setting scroll_limit.
17122 Limit scrolling to 100 screen lines.
17123 (redisplay_window): Even when falling back on "recentering",
17124 position point in the window according to scroll-conservatively,
17125 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
17127 (try_scrolling): When point is above the window, allow searching
17128 as far as scroll_max, or one screenful, to compute vertical
17129 distance from PT to the scroll margin position. This prevents
17130 try_scrolling from unnecessarily failing when
17131 scroll-conservatively is set to a value slightly larger than the
17132 window height. Clean up the case of PT below the margin at bottom
17133 of window: scroll_max can no longer be INT_MAX. When aggressive
17134 scrolling is in use, don't let point enter the opposite scroll
17135 margin as result of the scroll.
17136 (syms_of_xdisp) <scroll-conservatively>: Document the
17137 threshold of 100 lines for never-recentering scrolling.
17139 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
17141 * dispextern.h (move_it_by_lines):

17144 (message_log_check_duplicate): Remove parameters `prev_bol' and
17145 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
17146 (redisplay_internal): Remove parameter `preserve_echo_area',
17147 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
17149 * indent.c (Fvertical_motion):
17150 * window.c (window_scroll_pixel_based, Frecenter):
17151 Don't pass `need_y_p' to `move_it_by_lines'.
17153 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
17155 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
17156 steal a few bits to be more compact.
17157 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
17158 Remove unneeded casts.
17160 * bytecode.c (Fbyte_code): CAR and CDR can GC.
17162 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
17164 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
17165 binding" message (bug#7967).
17167 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
17169 Fix more problems found by GCC 4.6.0's static checks.
17171 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
17172 Remove unused local var.
17174 * editfns.c (Fmessage_box): Remove unused local var.
17176 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
17177 (note_mode_line_or_margin_highlight, note_mouse_highlight):
17178 Omit unused local vars.
17179 * window.c (shrink_windows): Omit unused local var.
17180 * menu.c (digest_single_submenu): Omit unused local var.
17181 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
17182 Omit unused local var.
17184 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
17185 Don't assume string length fits in int.
17186 (keyremap_step, read_key_sequence): Use size_t for sizes.
17187 (read_key_sequence): Don't check last_real_key_start redundantly.
17189 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
17190 instead of alloca (Bug#8344).
17192 * eval.c (Fbacktrace): Don't assume nargs fits in int.
17193 (Fbacktrace_frame): Don't assume nframes fits in int.
17195 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
17197 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
17200 * term.c (produce_glyphless_glyph): Remove unnecessary test.
17202 * cm.c (calccost): Turn while-do into do-while, for clarity.
17204 * keyboard.c (syms_of_keyboard): Use the same style as later
17205 in this function when indexing through an array. This also
17206 works around GCC bug 48267.
17208 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
17210 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
17212 * chartab.c (sub_char_table_ref_and_range): Redo for slight
17213 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
17215 * keyboard.c, keyboard.h (num_input_events): Now size_t.
17216 This avoids undefined behavior on integer overflow, and is a bit
17217 more convenient anyway since it is compared to a size_t variable.
17219 Variadic C functions now count arguments with size_t, not int.
17220 This avoids an unnecessary limitation on 64-bit machines, which
17221 caused (substring ...) to crash on large vectors (Bug#8344).

17231 * fns.c (concat): Likewise.
17232 * frame.c (x_set_frame_parameters): Likewise.
17233 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
17234 0 if not found, not -1. All callers changed.
17236 * alloc.c (garbage_collect): Don't assume stack size fits in int.
17237 (stack_copy_size): Now size_t, not int.
17238 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
17240 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
17242 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
17243 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
17244 All callers changed.
17246 * lisp.h (multibyte_char_to_unibyte):
17247 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
17248 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

17259 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
17260 don't set the hook to nil, but remove the offending function instead.
17261 (Qcommand_hook_internal): Remove, unused.
17262 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
17263 Vcommand_hook_internal.

17266 (funcall_nil, funcall_not): New functions.
17267 (run_hook_with_args): Call each function through a `funcall' argument.

17281 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
17282 All callers changed.
17284 * w32.c (_wsa_errlist): Use braces for struct initializers.
17286 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

17339 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
17341 * keyboard.c (timer_check): Remove parameter `do_it_now',

17444 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
17446 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
17447 unconditionally since it does the check itself.
17449 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
17451 Fix more problems found by GCC 4.5.2's static checks.
17453 * coding.c (encode_coding_raw_text): Avoid unnecessary test
17454 the first time through the loop, since we know p0 < p1 then.
17455 This also avoids a gcc -Wstrict-overflow warning.
17457 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
17458 leading to a memory leak, possible in functions like
17459 load_charset_map_from_file that can allocate an unbounded number
17460 of objects (Bug#8318).
17462 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
17463 that could (at least in theory) be that large.
17465 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
17466 This is less likely to overflow, and avoids undefined behavior if
17467 overflow does occur. All callers changed. Use strtoul to scan
17468 for the unsigned long integer.
17469 (pint2hrstr): Simplify and tune code slightly.
17470 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

17480 * fileio.c (Fcopy_file): Report error if fchown or fchmod
17483 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
17485 * process.c (Fmake_network_process): Use socklen_t, not int,
17486 where POSIX says socklen_t is required in portable programs.
17487 This fixes a porting bug on hosts like 64-bit HP-UX, where
17488 socklen_t is wider than int (Bug#8277).
17489 (Fmake_network_process, server_accept_connection):
17490 (wait_reading_process_output, read_process_output):
17493 * process.c: Rename or move locals to avoid shadowing.

17503 Make tparam.h and terminfo.c consistent.
17504 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
17505 Include tparam.h instead, since it declares them.
17506 * cm.h (PC): Remove extern decl; tparam.h now does this.
17507 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
17508 * terminfo.c: Include tparam.h, to check interfaces.
17509 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
17510 (tparam): Adjust signature to match interface in tparam.h;
17511 this removes some undefined behavior. Check that outstring and len
17512 are zero, which they always are with Emacs.
17513 * tparam.h (PC, BC, UP): New extern decls.
17515 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
17516 (xftfont_open): Rename locals to avoid shadowing.

17533 (find_automatic_composition, composition_adjust_point): Likewise.
17534 (composition_update_it): Mark var as initialized.
17535 (find_automatic_composition): Mark vars as initialized,
17536 with a FIXME (Bug#8290).

17540 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
17541 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
17542 (BUF_DEC_POS): Be more systematic about renaming local temporaries
17543 to avoid shadowing.
17545 * textprop.c (property_change_between_p): Remove; unused.
17547 * intervals.c (interval_start_pos): Now static.
17549 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

17555 Fix pointer signedness.
17556 (alsa_choose_format): Remove unused local var.
17557 (wav_play): Initialize a variable to 0, to prevent undefined
17558 behavior (Bug#8278).
17560 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
17562 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
17564 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
17565 clobbering (Bug#8298).
17566 * sysdep.c (sys_subshell): Likewise.
17567 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
17569 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
17570 This should get cleaned up, so that child_setup has the
17571 same signature on all platforms.
17573 * callproc.c (call_process_cleanup): Now static.
17574 (relocate_fd): Rename locals to avoid shadowing.
17576 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
17578 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
17579 not to be necessary, and produces flickering.
17581 2011-03-20 Glenn Morris <rgm@gnu.org>
17583 * config.in: Remove file.
17585 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

17615 (sigchld_handler): Now static.
17617 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
17618 That way, the code declares only the vars that it needs.

17628 (CONSTANTLIM): Remove; unused.
17629 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
17630 Define only if needed.
17632 * unexelf.c (unexec): Name an expression,
17633 to avoid gcc -Wbad-function-cast warning.
17634 Use a different way to cause a compilation error if anyone uses
17635 n rather than nn, a way that does not involve shadowing.
17636 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
17638 * deps.mk (unexalpha.o): Remove; unused.
17640 New file unexec.h, the (simple) interface for unexec (Bug#8267).

17714 * lisp.h (eassert): Check that the argument compiles, even if
17715 ENABLE_CHECKING is not defined.
17717 * data.c (Findirect_variable): Name an expression, to avoid
17718 gcc -Wbad-function-cast warning.

17730 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
17731 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
17733 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
17734 (GC_STRING_CHARS): Remove; not used.
17735 (Fmemory_limit): Cast sbrk's returned value to char *.

17761 (RETALLOC_IF): Define only if needed.
17762 (WORDCHAR_P): Likewise. This one is never needed, but is used
17763 only in a comment talking about a compiler bug, so put inside
17764 the #if 0 of that comment.

17792 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
17793 New macros, so that the caller can use some names other than
17794 gcpro1, gcpro2, etc.
17795 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
17797 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
17798 argument, for consistency with GCPRO2_VAR, etc: it is now the
17799 prefix of the variable, not the variable itself. All uses
17801 * dired.c (directory_files_internal, file_name_completion):
17802 Rename locals to avoid shadowing.
17804 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
17805 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
17806 dired.c's scmp function, had undefined behavior.
17807 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
17808 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
17809 * buffer.h: ... to here, because these macros use current_buffer,
17810 and the new implementation with inline functions needs to have
17811 current_buffer in scope now, rather than later when the macros
17813 (downcase, upcase1): New static inline functions.
17814 (DOWNCASE, UPCASE1): Reimplement using these functions.
17815 This avoids undefined behavior in expressions like
17816 DOWNCASE (x) == DOWNCASE (y), which previously suffered
17817 from race conditions in accessing the global variables
17818 case_temp1 and case_temp2.

17856 * buffer.c (fix_overlays_before): Mark locals as initialized.
17857 (fix_start_end_in_overlays): Likewise. This function should be
17858 simplified by using pointers-to-pointers, but that's a different

17867 to suppress a gcc -Wclobbered warning that does not seem to be right.
17868 (MAXPATHLEN): Define only if needed.
17870 * process.c (serial_open, serial_configure): Move decls from here ...
17871 * systty.h: ... to here, so that they can be checked.
17873 * fns.c (get_random, seed_random): Move extern decls from here ...
17874 * lisp.h: ... to here, so that they can be checked.
17876 * sysdep.c (reset_io): Now static.

17884 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
17885 (describe_map_tree):
17886 Rename locals to avoid shadowing.
17888 * keyboard.c: Declare functions static if they are not used elsewhere.

18230 -Wuninitialized does not deduce are never used uninitialized.
18231 (detect_coding_iso_2022): Initialize a local variable that might
18232 be used uninitialized. Leave a FIXME because it's not clear that
18233 this initialization is needed. (Bug#8211)
18234 (ISO_CODE_LF, ISO_CODE_CR, CODING_ISO_FLAG_EUC_TW_SHIFT):
18235 (ONE_MORE_BYTE_NO_CHECK, UTF_BOM, UTF_16_INVALID_P):
