3 * emacs.c: Move the inclusion of TERM_HEADER after including
4 windows.h on WINDOWSNT. This avoids compilation problems with
7 2012-10-01 Eli Zaretskii <eliz@gnu.org>
9 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
10 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
11 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
12 as the previous version used 'void *'.
14 * ralloc.c (ROUNDUP): Fix last change.
15 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
18 * w32proc.c <disable_itimers>: New static flag.
19 (init_timers): Initialize it to zero, after creating the critical
20 sections used by the timer threads.
21 (term_timers): Set to 1 before deleting the critical sections.
22 (getitimer, setitimer): If disable_itimers is non-zero, return an
23 error indication without doing anything. Reported by Fabrice
24 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
25 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
27 [!HAVE_SETITIMER]: Behave as the previous version that didn't
30 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
31 term_ntproc after all the other bookkeeping, to get timers working
34 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
36 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
37 Suggested by Juri Linkov in
38 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
40 Prefer plain 'static' to 'static inline' (Bug#12541).
41 With static functions, modern compilers inline pretty well by
42 themselves; advice from programmers often hurts as much as it helps.
43 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
44 this change shrinks the text size of the Emacs executable by 1.1%
45 without affecting CPU significantly in my benchmark.

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

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

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

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

468 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
470 Move Vlibrary_cache to emacs.c and reset before dumping.
472 * lisp.h (reset_image_types): Declare.
473 [WINDOWSNT] (Vlibrary_cache): Declare.
475 * image.c (reset_image_types): New function.
477 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.
478 (syms_of_emacs) [WINDOWSNT] <Vlibrary_cache>: Initialize and staticpro.
479 (Fdump_emacs): Reset Vlibrary_cache and image_types.
481 * w32.c (Vlibrary_cache): Do not define; moved to emacs.c

486 2012-09-25 Eli Zaretskii <eliz@gnu.org>
488 * w32proc.c (sys_signal): Handle all signals defined by the
489 MS-Windows runtime, not just SIGCHLD. Actually install the signal
490 handlers for signals supported by Windows. Don't override
491 term_ntproc as the handler for SIGABRT.
492 (sigaction): Rewrite to call sys_signal instead of duplicating its
494 (sys_kill): Improve commentary.
496 * w32.c (term_ntproc): Accept (and ignore) one argument, for
497 consistency with a signature of a signal handler. All callers
499 (init_ntproc): Accept an argument DUMPING. If dumping, don't
500 install term_ntproc as a signal handler for SIGABRT, as that
501 should be done by the dumped Emacs.
503 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
505 * w32select.c (term_w32select): Protect against repeated
506 invocation by setting clipboard_owner to NULL after calling
509 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
510 and term_ntproc to their modified signatures.
512 * character.c (char_string, string_char): Remove calls to
513 MAYBE_UNIFY_CHAR. See the discussion starting at
514 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
517 2012-09-25 Chong Yidong <cyd@gnu.org>

524 when encountering an unknown bytecode.
526 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
528 image.c, indent.c: Use bool for booleans.
529 * dispextern.h (struct image_type): Members valid_p, load, init
530 now return bool, not int. All uses changed.
531 * image.c: Omit unnecessary static decls.
532 (x_create_bitmap_mask, x_build_heuristic_mask):
533 Return void, not int, since callers don't care about the return value.

568 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
570 Move pid_t related decls out of lisp.h.
571 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
572 (interruptible_wait_for_termination):
573 Move these decls from lisp.h to syswait.h, since they use pid_t.
574 Needed on FreeBSD; see Herbert J. Skuhra in
575 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
576 * callproc.c: Include syswait.h.

596 Use bool for boolean.
597 * gtkutil.c (xg_update_frame_menubar):
598 * xmenu.c (update_frame_menubar):
599 Return void, not int, since caller ignores return value.

603 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
605 * makefile.w32-in (BLOCKINPUT_H): Remove.

624 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
625 fatal_error_backtrace.
627 * w32proc.c (sys_kill): Undo last change: don't do anything when
628 invoked to deliver SIGABRT to our own process. This is now
629 handled by emacs_raise.
631 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
633 * w32term.c (w32_read_socket): Remove leftover reference to
634 interrupt_input_pending.
636 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
638 Do not use SA_NODEFER.
639 Problem reported by Dani Moncayo in
640 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
642 * sysdep.c (emacs_abort): Do not reset signal handler.
643 * emacs.c (terminate_due_to_signal): Reset signal handler here.
644 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
645 wanted even on POSIXish hosts, and it doesn't work on Windows.
647 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
649 * xterm.c (x_term_init): Call fixup_locale before and after calling
650 gtk_init (Bug#12392).
652 2012-09-23 Chong Yidong <cyd@gnu.org>
654 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
655 Vdynamic_library_alist.
657 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
658 (Fgnutls_available_p): Caller changed.
660 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
661 (Flibxml_parse_xml_region): Likewise.
663 * dispextern.h (struct image_type): Remove arg from init function.
665 * image.c (Finit_image_library, lookup_image_type)
666 (define_image_type): Remove now-unneeded second arg.
667 (init_xpm_functions, init_png_functions, init_jpeg_functions)
668 (init_tiff_functions, init_gif_functions, init_svg_functions):
669 Arglist and w32_delayed_load calling convention changed.
670 (gs_type): Remove init_gs_functions; there is no such function.
671 (valid_image_p, make_image): Fix caller to lookup_image_type.
673 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
675 Simplify and avoid signal-handling races (Bug#12471).
677 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
678 Avoid recursive loop if there's a fatal error in the function itself.
679 * atimer.c (pending_atimers):
680 * blockinput.h: Don't include "atimer.h"; no longer needed.
681 (interrupt_input_pending): Remove. All uses removed.
682 pending_signals now counts both atimers and ordinary interrupts.
683 This is less racy than having three separate pending-signal flags.
684 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
686 Rename from their upper-case counterparts BLOCK_INPUT,
687 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
688 INPUT_BLOCKED_P, and turn into functions. All uses changed.
689 This makes it easier to access volatile variables more accurately.
690 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
691 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
692 that's more reliable if the code is buggy and sets
693 interrupt_input_blocked to a negative value. All uses changed.
694 * atimer.c (deliver_alarm_signal):
695 Remove. No need to deliver this to the parent; any thread can
696 handle this signal now. All uses replaced by underlying handler.
697 * atimer.c (turn_on_atimers):
698 * dispnew.c (handle_window_change_signal):
699 * emacs.c (handle_danger_signal):
700 * keyboard.c (kbd_buffer_get_event):
701 Don't reestablish signal handler; not needed with sigaction.
702 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
704 Rework to avoid unnecessary accesses to volatile variables.
705 (UNBLOCK_INPUT_TO): Now a function.
706 (totally_unblock_input, unblock_input): New decls.
707 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
708 (init_data): Remove. Necessary stuff now done in init_signal.
709 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
710 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
711 (fatal_error_code): Remove; no longer needed.
712 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
713 it doesn't always backtrace. All uses changed. No need to reset
714 signal to default, since sigaction and/or die does that for us now.
715 Use emacs_raise (FOO), not kill (getpid (), FOO).
716 (main): Check more-accurately whether we're dumping.
717 Move fatal-error setup to sysdep.c
718 * floatfns.c: Do not include "syssignal.h"; no longer needed.
719 * gtkutil.c (xg_get_file_name, xg_get_font):
720 Remove no-longer-needed signal-mask manipulation.
721 * keyboard.c, process.c (POLL_FOR_INPUT):
722 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
723 * keyboard.c (read_avail_input): Remove.
724 All uses replaced by gobble_input.
725 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
726 (kbd_buffer_store_event_hold, gobble_input):
727 (record_asynch_buffer_change) [USABLE_SIGIO]:
728 (store_user_signal_events):
729 No need to mess with signal mask.
730 (gobble_input): If blocking input and there are terminals, simply
731 set pending_signals to 1 and return. All hooks changed to not
732 worry about whether input is blocked.
733 (process_pending_signals): Clear pending_signals before processing
734 them, in case a signal comes in while we're processing.
735 By convention callers now test pending_signals before calling us.
736 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
737 New functions, to support changes to blockinput.h.
738 (handle_input_available_signal): Now extern.
739 (reinvoke_input_signal): Remove. All uses replaced by
741 (quit_count): Now volatile, since a signal handler uses it.
742 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
743 All callers changed. Block SIGINT only if not already blocked.
744 Clear sigmask reliably, even if Fsignal returns, which it can.
745 Omit unnecessary accesses to volatile var.
746 (quit_throw_to_read_char): No need to restore sigmask.
747 * keyboard.c (gobble_input, handle_user_signal):
748 * process.c (wait_reading_process_output):
749 Call signal-handling code rather than killing ourselves.
750 * lisp.h: Include <float.h>, for...
751 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
752 (pending_signals): Now volatile.
753 (syms_of_data): Now const if IEEE floating point.
754 (handle_input_available_signal) [USABLE_SIGIO]:
755 (terminate_due_to_signal, record_child_status_change): New decls.
756 * process.c (create_process): Avoid disaster if memory is exhausted
757 while we're processing a vfork, by tightening the critical section
759 (send_process_frame, process_sent_to, handle_pipe_signal)
760 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
762 (send_process): No need for setjmp/longjmp any more, since the
763 SIGPIPE stuff is now gone. Instead, report an error if errno
765 (record_child_status_change): Now extern. PID and W are now args.
766 Return void, not bool. All callers changed.
767 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
768 Remove. All uses removed. This bug should be fixed now in a
770 (wait_for_termination_1): Use waitpid rather than sigsuspend,
771 and record the child status change directly. This avoids the
772 need to futz with the signal mask.
773 (process_fatal_action): Move here from emacs.c.
774 (emacs_sigaction_flags): New function, containing
775 much of what used to be in emacs_sigaction_init.
776 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
777 caught by emacs, to make races less likely.
778 (deliver_process_signal): Rename from handle_on_main_thread.
780 (BACKTRACE_LIMIT_MAX): Now at top level.
781 (thread_backtrace_buffer, threadback_backtrace_pointers):
783 (deliver_thread_signal, deliver_fatal_thread_signal):
784 New functions, for more-accurate delivery of thread-specific signals.
785 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
786 (deliver_arith_signal): Handle in this thread, not
787 in the main thread, since it's triggered by this thread.
788 (maybe_fatal_sig): New function.
789 (init_signals): New arg DUMPING so that we can be more accurate
790 about whether we're dumping. Caller changed.
791 Treat thread-specific signals differently from process-general signals.
792 Block all signals while handling fatal error; that's safer.
793 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
795 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
796 Ignore SIGPIPE unless batch.
797 (emacs_backtrace): Output backtrace for the appropriate thread,
798 which is not necessarily the main thread.
799 * syssignal.h: Include <stdbool.h>.
800 (emacs_raise): New macro.
801 * xterm.c (x_connection_signal): Remove; no longer needed
802 now that we use sigaction.
803 (x_connection_closed): No need to mess with sigmask now.
804 (x_initialize): No need to reset SIGPIPE handler here, since
805 init_signals does this for us now.
807 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
809 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
810 background rect may be larger (Bug#12245).
812 2012-09-23 Chong Yidong <cyd@gnu.org>
814 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
816 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
818 * .gdbinit: Just stop at fatal_error_backtrace.
819 See Stefan Monnier's request in
820 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
821 Remove no-longer-used query of system type.
823 2012-09-22 Chong Yidong <cyd@gnu.org>
825 * search.c (Freplace_match): Doc fix (Bug#12325).
827 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
829 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
830 (Fline_end_position): Doc fix.
832 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
834 2012-09-22 Chong Yidong <cyd@gnu.org>
836 * dispextern.h (struct image_type): Add new slot, storing a type
837 initialization function.
839 * image.c (define_image_type): Call the image initializer function
840 if it is defined. Arguments and return value changed.
841 (valid_image_p, make_image): Callers changed.
842 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
843 (gif_type, imagemagick_type, svg_type, gs_type):
844 Add initialization functions.
845 (Finit_image_library): Call lookup_image_type.
846 (CHECK_LIB_AVAILABLE): Macro deleted.
847 (lookup_image_type): Call define_image_type here, rather than via
848 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
849 (syms_of_image): Move define_image_type calls for xbm_type and
850 pbm_type to lookup_image_type.
852 2012-09-22 Eli Zaretskii <eliz@gnu.org>
854 * keyboard.c (timer_check_2): Move calculation of 'timers' and
855 'idle_timers' from here ...
856 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
857 lists, to avoid infloops when the timer does something stupid,
858 like reinvoke itself with the same or smaller time-out.
861 2012-09-22 Martin Rudalics <rudalics@gmx.at>
863 * window.c (Fsplit_window_internal): Handle only Qt value of
864 Vwindow_combination_limit separately.

871 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
872 the new overlay string. (Bug#10159)
874 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
876 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
877 or that fprintf is async-signal-safe. POSIX doesn't require
880 2012-09-22 Chong Yidong <cyd@gnu.org>
882 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
885 2012-09-22 Kenichi Handa <handa@gnu.org>
887 * composite.c (composition_reseat_it): Handle the case that a
888 grapheme cluster is not covered by a single font (Bug#12352).
890 2012-09-21 Chong Yidong <cyd@gnu.org>
892 * image.c (define_image_type): Avoid adding duplicate types to
893 image_types (Bug#12463). Suggested by Jörg Walter.
895 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
897 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
898 (print_load_command_name): Add case LC_DATA_IN_CODE.
899 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
901 2012-09-21 Glenn Morris <rgm@gnu.org>

904 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
906 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
908 * fileio.c (Ffile_selinux_context): Only call freecon when
909 lgetfilecon succeeded.
910 (Fset_file_selinux_context): Likewise. (Bug#12444)
912 2012-09-21 Eli Zaretskii <eliz@gnu.org>
914 * xdisp.c (try_window_reusing_current_matrix): Under bidi
915 reordering, locate the cursor by calling set_cursor_from_row; if
916 that fails, clear the desired glyph matrix before returning a
917 failure indication to the caller. Fixes leaving garbled display
918 when fast scrolling with a down-key. (Bug#12403)
919 (compute_stop_pos_backwards): Fix a typo that caused crashes while
920 scrolling through multibyte text.
922 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
924 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
925 calling mark_vectorlike since that's the one that marks the window.
926 (mark_discard_killed_buffers): Mark the final cdr.
927 * window.h (struct window): Move prev/next_buffers to the
929 * window.c (make_window): Initialize prev/next_buffers manually.
931 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
933 Omit unused arg EXPECTED from socket hooks.
934 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
935 * nsterm.m (ns_term_init):
936 * termhooks.h (struct terminal.read_socket_hook):
937 * w32inevt.c (w32_console_read_socket):
938 * w32term.c (w32_read_socket):
939 * xterm.c (XTread_socket):
940 Omit unused arg EXPECTED. All callers changed.
941 (store_user_signal_events): Return void, not int, since callers no
942 longer care about the return value. All uses changed.
944 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
946 * w32gui.h (XParseGeometry): Do not declare.
948 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
950 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
951 Ignore 'expected'. See Eli Zaretskii in
952 <http://bugs.gnu.org/12471#8> (last line).
954 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
955 (XParseGeometry): Now static. Substitute extremal values for
956 values that are out of range.
958 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
960 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
962 * nsfns.m (XParseGeometry): Remove.
963 (Fx_create_frame): Call x_set_offset to correctly interpret
966 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
967 (Fx_parse_geometry): If there is a space in string, call
968 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
970 2012-09-17 Eli Zaretskii <eliz@gnu.org>
972 * search.c (scan_buffer): Use character positions in calls to
973 region_cache_forward and region_cache_backward, not byte
974 positions. (Bug#12196)
976 * w32term.c (w32_read_socket): Set pending_signals to 1, like
977 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
979 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
980 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
981 emacs_blocked_malloc, now deleted.
983 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
985 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
986 The workaround was for improving performance on Solaris 2.4, but
987 is getting in the way now. Emacs will still work if someone is
988 still running Solaris 2.4 in a museum somewhere; Sun dropped
989 support for Solaris 2.4 in 2003.
990 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
991 * process.c (create_process) [HAVE_WORKING_VFORK]:
992 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
993 since Emacs no longer uses vfork on that platform.
995 2012-09-17 Glenn Morris <rgm@gnu.org>
997 * emacs.c: Use COPYRIGHT.
999 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
1001 Remove configure's --without-sync-input option (Bug#12450).
1002 When auditing signal-handling in preparation for cleaning it up,
1003 I found that SYNC_INPUT has race conditions and would be a real
1004 pain to fix. Since it's an undocumented and deprecated
1005 configure-time option, now seems like a good time to remove it.
1006 Also see <http://bugs.gnu.org/11080#16>.
1007 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
1008 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
1009 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
1010 (malloc_hysteresis):
1011 (check_depth) [XMALLOC_OVERRUN_CHECK]:
1012 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
1013 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
1014 (dont_register_blocks, bytes_used_when_reconsidered)
1015 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
1016 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
1017 [!SYSTEM_MALLOC && !SYNC_INPUT]:
1018 Remove. All uses removed.
1019 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
1020 implementation, one that depends on whether the new macro
1021 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
1023 * atimer.c (run_timers, handle_alarm_signal):
1024 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
1025 (handle_async_input, process_pending_signals)
1026 (handle_input_available_signal, init_keyboard):
1027 * nsterm.m (ns_read_socket):
1028 * process.c (wait_reading_process_output):
1029 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
1030 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
1032 * xterm.c (XTread_socket):
1034 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
1035 * eval.c (handling_signal): Remove. All uses removed.
1036 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
1037 All uses replaced with the SYNC_INPUT version.
1038 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
1040 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1043 * font.c (Ffont_shape_gstring): Remove unused local.
1045 2012-09-16 Glenn Morris <rgm@gnu.org>
1047 * Makefile.in (clean): No longer run nextstep's clean.
1049 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
1051 (ns-app): Move here from ns.mk, and simplify.
1052 (clean): Simplify nextstep entry.
1053 * ns.mk: Remove file.
1055 2012-09-17 Kenichi Handa <handa@gnu.org>
1057 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
1058 not covert the last few charactes.
1060 2012-09-16 Kenichi Handa <handa@gnu.org>
1062 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
1063 here, but just check the validity of glyphs in the glyph-string.
1065 2012-09-16 Martin Rudalics <rudalics@gmx.at>
1067 * window.c (Fwindow_parameter, Fset_window_parameter):
1068 Accept any window as argument (Bug#12452).
1070 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
1072 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
1073 to ns_term_init to avoid memory leak.
1075 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
1076 explicit retain/release.
1077 (ns_term_init): Only allow one display. Initialize outerpool and
1080 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1082 Port _setjmp fix to POSIXish hosts as well as Microsoft.
1083 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
1084 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
1085 the Microsoft problem in a different way, by altering ../nt/config.nt.
1087 2012-09-15 Eli Zaretskii <eliz@gnu.org>
1102 * w16select.c: Remove inclusion of setjmp.h, as it is now included
1103 by lisp.h. This completes removal of setjmp.h inclusion
1104 erroneously announced in the previous commit. (Bug#12446)
1106 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
1109 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
1110 not defined as a macro. The latter happens on MS-Windows.
1113 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1115 Port better to POSIX hosts lacking _setjmp (Bug#12446).
1116 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
1117 Some instances of '#include <setjmp.h>' removed, if the
1118 only reason for the instance was because "lisp.h" was included.
1119 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
1120 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
1121 and _longjmp with the new symbols. Emacs already uses _setjmp if
1122 available, so this change affects only POSIXish hosts that have
1123 sigsetjmp but not _setjmp, such as some versions of Solaris and
1124 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
1125 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
1126 (png_load_body) [HAVE_PNG]:
1127 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
1128 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
1129 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
1130 since PNG requires jmp_buf. This is the only exception to the
1131 general rule that we now use sys_setjmp and sys_longjmp.
1132 This exception is OK since this code does not change the signal
1133 mask or longjmp out of a signal handler.
1135 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
1137 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
1138 Include "syssignal.h", for 'main_thread'.
1140 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
1142 Avoid out-of-range marker position (Bug#12426).
1143 * insdel.c (replace_range, replace_range_2):
1144 Adjust markers before overlays, as suggested by comments.
1145 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
1146 Remove redundant check before calling offset_intervals.
1148 2012-09-14 Martin Rudalics <rudalics@gmx.at>
1150 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
1151 current buffer (Bug#12387).
1153 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
1155 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
1157 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
1159 Use a more backwards-compatible timer format (Bug#12430).
1160 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
1161 vector element, not from the 4th, since PSECS is now at the end.
1162 (Fcurrent_idle_time): Doc fix.
1164 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
1166 Function to mark objects and remove killed buffers at once.
1167 * alloc.c (discard_killed_buffers): Rename to ...
1168 (mark_discard_killed buffers) ... new name. Add marking
1169 of remaining objects. Fix comment. Adjust users.
1170 (mark_object): Do not touch frame buffer lists here.
1171 * frame.c (delete_frame): Reset frame buffer lists here.
1173 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
1175 Better workaround for GNOME bug when --enable-gcc-warnings.
1176 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
1177 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
1178 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
1180 Simplify SIGIO usage (Bug#12408).
1181 The code that dealt with SIGIO was crufty and confusing, e.g., it
1182 played tricks like "#undef SIGIO" but these tricks were not used
1183 consistently. Simplify mostly by not #undeffing standard symbols,
1184 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
1185 or not as we please) rather than "defined SIGIO" (standard symbol
1186 that we probably shouldn't #undef).
1187 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
1188 Modules that need it can include it.
1189 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
1190 * dispextern.h (ignore_sigio): New decl.
1191 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
1192 unconditionally, since it's now a no-op if !USABLE_SIGIO.
1193 * emacs.c (shut_down_emacs):
1194 * keyboard.c (kbd_buffer_store_event_hold):
1195 Use ignore_sigio rather than invoking 'signal' directly.
1196 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
1198 (FIONREAD, SIGIO): Do not #undef.
1199 (tty_read_avail_input): Use #error rather than a syntax error.
1200 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
1201 for I_PIPE, used by SETUP_SLAVE_PTY.
1202 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
1203 * sysdep.c (croak): Remove; no longer needed. This bit of
1204 temporary code, with Fred N. Fish's comment that it's temporary,
1205 has been in Emacs since at least 1992!
1206 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
1207 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
1208 * syssignal.h (croak): Remove decl.
1209 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
1210 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
1211 now that we're termios-only.
1212 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
1213 * term.c (dissociate_if_controlling_tty): Use #error rather than
1216 Work around GCC and GNOME bugs when --enable-gcc-warnings.
1217 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
1218 to work around GNOME bug 683906.
1219 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
1220 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
1221 This works around GCC bug 54561.
1223 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
1225 More fixes for 'volatile' and setjmp/longjmp.
1226 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
1227 * image.c (struct png_load_context) [HAVE_PNG]: New type.
1228 (png_load_body) [HAVE_PNG]:
1229 (jpeg_load_body) [HAVE_JPEG]:
1230 New function, with most of the old parent function's body.
1231 (png_load) [HAVE_PNG]:
1232 (jpeg_load) [HAVE_JPEG]:
1233 Invoke the new function, to avoid longjmp munging our locals.
1234 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
1235 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
1236 longjmp is passed 2, as the C standard doesn't guarantee this.
1237 Instead, store the failure code into mgr->failure_code.
1239 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
1241 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
1242 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
1243 (syms_of_keyboard): Remove support for unread-command-char.
1245 2012-09-12 Eli Zaretskii <eliz@gnu.org>
1247 * w32proc.c (sys_kill): If PID is our process ID and the signal is
1248 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
1249 violation. (Bug#12426)
1251 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
1253 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
1255 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
1257 * eval.c: Add `inhibit-debugger'.
1258 (Qinhibit_debugger): New symbol.
1259 (call_debugger): Bind it instead of Qdebug_on_error.
1260 (maybe_call_debugger): Test Vinhibit_debugger.
1261 (syms_of_eval): Define inhibit-debugger.
1262 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
1263 (syms_of_xdisp): Remove inhibit-debug-on-message.
1265 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
1267 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
1268 If a nonvolatile local variable is written before a _longjmp to
1269 the frame containing the variable, and is read after the _longjmp,
1270 the value read is indeterminate. Some local variables of type
1271 'struct handler' and 'struct catchtag' are used in this way, so
1272 mark each of their slots as volatile if the slot can be set before
1273 _longjmp and read afterwards.
1274 * lisp.h (struct handler): var and chosen_clause are now volatile.
1275 (struct catchtag): val, next, and pdlcount are now volatile.
1277 * bidi.c (bidi_push_it, bidi_pop_it):
1278 * fns.c (copy_hash_table):
1279 * image.c (define_image_type):
1280 * keyboard.c (kbd_buffer_store_event_hold):
1281 * process.c (Fprocess_send_eof):
1282 * xfaces.c (x_create_gc) [HAVE_NS]:
1283 * xgselect.c (xg_select):
1284 Prefer assignment to memcpy when either will do.
1286 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
1287 Use pointer-to-a-pointer to simplify and avoid a NILP check each
1288 time an item is removed. No need to mark this function 'inline';
1289 the compiler knows better than we do.
1291 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
1293 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
1294 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
1295 to change_frame_size (Bug#12388).
1296 (windowDidResize:): Pass YES to updateFrameSize.
1298 * nsterm.h: Add delay parameter to updateFrameSize.
1300 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
1302 Discard killed buffers from deleted window and frame objects.
1303 This reduces an amount of references to killed buffers and
1304 helps GC to reclaim them faster.
1305 * alloc.c (discard_killed_buffers): New function.
1306 (mark_object): Use it for deleted windows and frames.
1307 (mark_object): If symbol's value is set up for a killed buffer
1308 or deleted frame, restore it's global binding.
1309 * data.c (swap_in_global_binding): Add GC notice.
1310 (swap_in_symval_forwarding): Use convenient set_blv_where.
1311 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
1312 * window.h: ... to here.
1314 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
1316 Convenient macro to check whether the buffer is live.
1317 * buffer.h (BUFFER_LIVE_P): New macro.
1318 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
1319 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
1321 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1323 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
1324 composition cases (Bug#12364).
1326 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
1327 overhang of succeeding glyphs overlapping box cursor.
1329 * w32term.c (x_draw_glyph_string): Likewise.
1331 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
1333 Simplify, document, and port floating-point (Bug#12381).
1334 The porting part of this patch fixes bugs on non-IEEE platforms
1335 with frexp, ldexp, logb.
1336 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
1338 * floatfns.c: Simplify discussion of functions that Emacs doesn't
1339 support, by removing commented-out code and briefly listing the
1340 C89 functions excluded. The commented-out stuff was confusing
1341 maintenance, e.g., we thought we needed cbrt but it was commented out.
1342 (logb): Remove decl; no longer needed.
1343 (isfinite): New macro, if not already supplied.
1344 (isnan): Don't replace any existing macro.
1345 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
1346 are present on all C89 platforms.
1347 (Ffrexp): Do not special-case zero, as frexp does the right thing
1349 (Flogb): Do not use logb, as it doesn't have the desired meaning
1350 on hosts that use non-base-2 floating point. Instead, stick with
1351 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
1352 frexp, to avoid getting an unspecified result.
1354 * xdisp.c (Qinhibit_debug_on_message): Now static.
1356 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
1358 * nsterm.m (ns_update_begin): Set clip path to whole view by using
1359 NSBezierPath (Bug#12131).
1361 2012-09-10 Chong Yidong <cyd@gnu.org>
1363 * fns.c (Fdelq, Fdelete): Doc fix.
1365 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
1367 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
1368 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
1370 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
1372 * lisp.h (make_lisp_ptr): New macro to replace XSET.
1373 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
1376 2012-09-09 Eli Zaretskii <eliz@gnu.org>
1378 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
1379 left fringe if the window has a left margin. This avoids leaving
1380 traces of the cursor because its leftmost pixel is not drawn over.
1382 * dispnew.c (update_window_line): When the left margin area of a
1383 screen line is updated, set the redraw_fringe_bitmaps_p flag of
1384 that screen line. (Bug#12277)
1386 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
1388 Assume C89 or later for math functions (Bug#12381).
1389 This simplifies the code, and makes it a bit smaller and faster,
1390 and (most important) makes it easier to clean up signal handling
1391 since we can stop worring about floating-point exceptions in
1392 library code. That was a problem before C89, but the problem
1393 went away many years ago on all practical Emacs targets.
1394 * data.c, image.c, lread.c, print.c:
1395 Don't include <math.h>; no longer needed.
1396 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
1397 might be autoconfigured, as that never happens.
1399 * doprnt.c (DBL_MAX_10_EXP):
1400 * print.c (DBL_DIG):
1401 Remove. C89 or later always defines these.
1402 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
1403 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
1404 (arith_error, domain_error, domain_error2):
1405 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
1406 no longer needed -- we simply return what C returns. All uses removed.
1407 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
1409 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
1410 Remove. All uses expanded, as these macros are no longer used
1411 more than once and are now more trouble than they're worth.
1412 (Ftan): Use tan, not sin / cos.
1413 (Flogb): Assume C89 frexp.
1414 (fmod_float): Assume C89 fmod.
1415 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
1416 (init_floatfns): Remove. All uses removed.
1418 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1420 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
1421 compositeToPoint for OSX < 10.6 (Bug#12390).
1423 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
1425 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
1426 This produces more-accurate results.
1428 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1430 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
1431 changes (Bug#12088).
1433 2012-09-08 Chong Yidong <cyd@gnu.org>
1435 * syntax.c (Fstring_to_syntax): Doc fix.
1437 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1439 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
1440 in the internal border.
1441 (x_set_window_size): Remove static variables and their usage.
1442 (ns_redraw_scroll_bars): Fix NSTRACE arg.
1443 (ns_after_update_window_line, ns_draw_fringe_bitmap):
1444 Remove fringe/internal border adjustment (Bug#11052).
1445 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
1446 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
1447 (ns_fix_rect_ibw): Remove.
1448 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
1449 (ns_dumpglyphs_box_or_relief): Ditto.
1450 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
1452 (ns_dumpglyphs_image): Ditto.
1453 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
1455 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
1456 their usage. Add fringe_extended_p and its use as in other terms.
1457 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
1458 scroll bar was removed.
1459 (updateFrameSize): New function.
1460 (windowDidResize): Move code to updateFrameSize and call it.
1462 * nsterm.h (EmacsView): Add updateFrameSize.
1464 2012-09-07 Chong Yidong <cyd@gnu.org>
1466 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
1468 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
1470 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1472 More signal-handler cleanup (Bug#12327).
1473 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
1474 Problem introduced when merging patches. Noted by Eli Zaretskii in
1475 <http://bugs.gnu.org/12327#67>.
1476 * floatfns.c: Comment fix.
1477 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
1478 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
1479 and anyway the declaration is harmless even if SIGDANGER is not defined.
1480 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
1481 defined BROKEN_FIONREAD). systty.h formerly did this, but other
1482 source files not surprisingly expected syssignal.h to define, or
1483 not define, SIGIO, and it's cleaner to do it that way, for consistency.
1484 Include <sys/ioctl.h>, for FIONREAD.
1485 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
1486 This eliminates a problem whereby other files mysteriously had
1487 to include "syssignal.h" before including "systty.h" if they
1488 wanted to use "#ifdef SIGIO".
1490 2012-09-07 Eli Zaretskii <eliz@gnu.org>
1492 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
1494 * w32.c (sigemptyset): Empty the set.
1495 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
1497 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
1499 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
1501 * alloc.c (mark_buffer): Revert unsafe marking optimization.
1502 (mark_object): Likewise for frame objects.
1504 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1506 * syssignal.h (handle_on_main_thread): Always declare,
1507 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
1508 This ports to platforms without HAVE_PTHREAD.
1510 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1512 Signal-handler cleanup (Bug#12327).
1513 Emacs's signal handlers were written in the old 4.2BSD style with
1514 sigblock and sigmask and so forth, and this led to some
1515 inefficiencies and confusion. Rewrite these to use
1516 pthread_sigmask etc. without copying signal sets around. Also,
1517 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
1518 'signal', and instead use functions that do not attempt to take
1519 over the system name space. This patch causes Emacs's text
1520 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
1521 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
1522 Do not include <signal.h> or "syssignal.h", as these
1523 modules do not use signals.
1524 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
1525 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
1526 Do not include <signal.h>, as "syssignal.h" does that for us now.
1527 * atimer.c (sigmask_atimers): New function.
1528 (block_atimers, unblock_atimers): New functions,
1529 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
1531 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
1532 no longer needed here.
1533 * emacs.c (main): Inspect existing signal handler with sigaction,
1534 so that there's no need to block and unblock SIGHUP.
1535 * sysdep.c (struct save_signal): New member 'action', replacing
1536 old member 'handler'.
1537 (save_signal_handlers, restore_signal_handlers):
1538 Use sigaction instead of 'signal' to save and restore.
1539 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
1540 New function. All users of 'signal' modified to use set_sighandler
1541 if they're writeonly, and to use sys_signal if they're read+write.
1542 (emacs_sigaction_init, forwarded_signal): New functions.
1543 (sys_signal): Remove. All uses replaced by calls to sigaction
1544 and emacs_sigaction_init, or by direct calls to 'signal'.
1545 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
1546 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
1547 all uses replaced by pthread_sigmask etc. calls.
1548 * syssignal.h: Include <signal.h>.
1549 (emacs_sigaction_init, forwarded_signal): New decls.
1550 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
1551 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
1552 (sigmask, sys_sigmask): Remove; no longer needed.
1553 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
1554 (sigblock, sigunblock, sigfree):
1555 (sigsetmask) [!defined sigsetmask]:
1556 Remove. All uses replaced by pthread_sigmask.
1557 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
1558 no longer need to be replaced, and its typical old uses
1559 are now done via emacs_sigaction_init and sigaction.
1560 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
1561 (sys_sigdel): Remove; unused.
1562 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
1564 2012-09-06 Eli Zaretskii <eliz@gnu.org>
1566 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
1567 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
1569 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1571 Explicitly mark buffer_defaults and buffer_local_symbols.
1572 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
1573 mark_local_symbols here.
1574 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
1575 since special buffers aren't marked here any more.
1576 (allocate_buffer): Chain new buffer with all_buffers here...
1577 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
1579 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
1580 (syms_of_buffer): Remove staticpro of the above.
1581 (init_buffer_once): Set names for buffer_defaults and
1582 buffer_local_symbols.
1584 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1586 Use bool for booleans in font-related modules.
1587 * font.c (font_intern_prop, font_style_to_value)
1588 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
1589 (generate_otf_features, font_check_otf_features, font_check_otf)
1590 (font_match_p, font_list_entities, font_at):
1591 * fontset.c (fontset_id_valid_p, reorder_font_vector
1592 (fontset_find_font, Fset_fontset_font)
1593 (face_suitable_for_char_p) [0]:
1594 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
1595 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
1596 (m17n_flt_initialized, ftfont_shape_by_flt):
1597 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
1598 * nsfont.m (nsfont_draw):
1599 * w32font.c (w32font_draw):
1600 * w32term.c (x_draw_glyphless_glyph_string_foreground):
1601 Use bool for booleans.
1602 * font.h: Adjust to above API changes.
1603 (struct font, struct font_driver, struct font_driver_list):
1604 Use bool for booleans.
1605 (struct font): Remove useless member encoding_type.
1607 * fontset.c, xftfont.c: Omit unnecessary static decls.
1609 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1611 * alloc.c (mark_object): Revert window marking code
1612 since it's unsafe for the Fset_window_configuration.
1614 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1616 Fix race conditions with signal handlers and errno (Bug#12327).
1617 Be more systematic about preserving errno whenever a signal
1618 handler returns, even if it's not in the main thread. Do this by
1619 renaming signal handlers to distinguish between signal delivery
1620 and signal handling. All uses changed.
1621 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
1622 * data.c (deliver_arith_signal): Rename from arith_error.
1623 * dispnew.c (deliver_window_change_signal): Rename from
1624 window_change_signal.
1625 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
1626 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
1627 * keyboard.c (deliver_input_available_signal): Rename from
1628 input_available_signal.
1629 (deliver_user_signal): Rename from handle_user_signal.
1630 (deliver_interrupt_signal): Rename from interrupt_signal.
1631 * process.c (deliver_pipe_signal): Rename from send_process_trap.
1632 (deliver_child_signal): Rename from sigchld_handler.
1633 * atimer.c (handle_alarm_signal):
1634 * data.c (handle_arith_signal):
1635 * dispnew.c (handle_window_change_signal):
1636 * emacs.c (handle_fatal_signal, handle_danger_signal):
1637 * keyboard.c (handle_input_available_signal):
1638 * keyboard.c (handle_user_signal, handle_interrupt_signal):
1639 * process.c (handle_pipe_signal, handle_child_signal):
1640 New functions, with the actual signal-handling code taken from the
1641 original respective signal handlers, sans the sporadic attempts to
1642 preserve errno, since that's now done by handle_on_main_thread.
1643 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
1644 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
1645 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1647 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1648 Move initialization of main_thread to sysdep.c's init_signals.
1649 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
1650 our usage, and simplifies the mainline code.
1651 (record_child_status_change): New static function, as a helper
1652 for handle_child_signal, and with most of the old child handler's
1654 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
1655 (handle_child_signal): Use the above.
1656 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1657 Moved here from emacs.c.
1658 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
1659 code moved here from emacs.c's main function.
1660 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
1661 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
1662 This lets callers save and restore errno properly.
1664 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1666 Remove redundant or unused things here and there.
1667 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
1668 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
1669 * editfns.c (Fcompare_buffer_substrings): Likewise.
1670 * frame.h (struct terminal, struct font_driver_list):
1671 Remove redundant declarations.
1672 * window.h (Qleft, Qright): Likewise.
1674 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1676 Do not mark objects from deleted buffers, windows and frames.
1677 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
1678 (mark_object): Likewise for windows and frames.
1680 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1682 * alloc.c (valid_lisp_object_p): Treat killed buffers,
1683 buffer_defaults and buffer_local_symbols as valid objects.
1684 Return special value to denote them.
1686 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1688 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
1689 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
1690 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
1691 (file_name_absolute_p, Fsubstitute_in_file_name):
1692 (check_executable, check_writable, Ffile_accessible_directory_p)
1693 (Fset_file_selinux_context, Fdefault_file_modes)
1694 (Finsert_file_contents, choose_write_coding_system)
1695 (Fwrite_region, build_annotations, a_write, e_write)
1697 * filelock.c (boot_time_initialized, get_boot_time)
1698 (get_boot_time_1, lock_file_1, within_one_second):
1699 * floatfns.c (in_float):
1700 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
1701 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
1702 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
1703 * lisp.h (struct Lisp_Hash_Table.cmpfn):
1704 * window.c (compare_window_configurations):
1705 Use bool for booleans.
1706 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
1707 (Fdefault_file_modes): Now mode_t, not int, for modes.
1708 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
1709 (internal_delete_file): Now returns void, not a (boolean) int,
1710 since nobody was looking at the return value.
1711 * lisp.h, window.h: Adjust to above API changes.
1713 * xdisp.c (set_message): Simplify and reindent last change.
1715 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
1717 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
1719 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
1721 * eval.c (call_debugger): Make the function non-static so that we
1722 can call it from set_message.
1724 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
1725 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
1727 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1729 Give more-useful info on a fatal error (Bug#12328).
1730 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
1731 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
1732 of doing the work ourselves.
1733 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
1734 do most of the work.
1735 (fatal_error_backtrace): New function, taken from the guts
1736 of the old fatal_error_signal, but with a new option to output
1738 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
1739 info about the signal than just its number.
1740 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
1741 * sysdep.c: Include <execinfo.h>
1742 (emacs_backtrace): New function, taken partly from the previous
1743 code of the 'die' function.
1744 (emacs_abort): Call fatal_error_backtrace rather than abort.
1746 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
1748 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
1749 eager (load-time) macro-expansion.
1750 * lisp.mk (lisp): Add macroexp.
1752 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1754 Simplify redefinition of 'abort' (Bug#12316).
1755 Do not try to redefine the 'abort' function. Instead, redo
1756 the code so that it calls 'emacs_abort' rather than 'abort'.
1757 This removes the need for the NO_ABORT configure-time macro
1758 and makes it easier to change the abort code to do a backtrace.
1759 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
1760 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
1761 Remove; sysdep.c's emacs_abort now takes its place.
1762 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
1763 'abort' changed to use 'emacs_abort'.
1764 * msdos.c (dos_abort) [defined abort]: Remove; not used.
1765 (abort) [!defined abort]: Rename to ...
1766 (emacs_abort): ... new name.
1767 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
1768 the place of the old 'abort' in emacs.c.
1769 * w32.c, w32fns.c (abort): Do not #undef.
1770 * w32.c (emacs_abort): Rename from w32_abort.
1772 2012-09-04 Eli Zaretskii <eliz@gnu.org>
1774 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
1775 offsets[j].dv, since the y axis of the screen coordinates points
1776 down, while the y axis of the font definition coordinates points
1777 up. This fixes display of Arabic diacritics such as KASRA and
1778 KASRATAN. (Bug#11860)
1780 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1782 Be more systematic about _setjmp vs setjmp.
1783 * alloc.c (test_setjmp, mark_stack):
1784 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
1785 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
1786 (png_load, my_error_exit, jpeg_load):
1787 * process.c (send_process_trap, send_process):
1788 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
1789 The underscored versions are up to 30x faster on some hosts.
1790 Formerly, the code used setjmp+longjmp sometimes and
1791 _setjmp+_longjmp at other times, with no particular reason to
1792 prefer setjmp+longjmp.
1794 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
1796 Fix minor problem found by static checking.
1797 * buffer.c (Fdelete_all_overlays): Return nil.
1799 2012-09-03 Martin Rudalics <rudalics@gmx.at>

1926 offset adjustment values separately for each cluster. (Bug#11860)
1928 * image.c: Restore mistakenly removed inclusion of w32.h. Without
1929 it, GCC doesn't see prototypes of w32_delayed_load, and complains
1930 about implicit conversions from integer to pointer.
1932 2012-09-01 Daniel Colascione <dancol@dancol.org>

1988 window system declarations.
1990 * frame.h: Move common functions here: set_frame_menubar,
1991 x_set_window_size, x_sync, x_get_focus_frame,

2080 Add window_closed and button_values. Add void as return value for
2081 add(Button|String|Split). addButton takes int instead of Lisp_Object.
2082 Add process_dialog as new member.

2247 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
2249 Special MEM_TYPE_SPARE to denote reserved memory.
2250 * alloc.c (enum mem_type): New memory type.
2251 (refill_memory_reserve): Use new type for spare memory.
2252 This prevents live_cons_p and live_string_p from incorrect
2253 detection of uninitialized objects from spare memory as live.
2255 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
2258 * Makefile.in (.PHONY): versioclean -> versionclean.
2260 Remove unused external symbols.
2261 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
2262 * window.c (Qwindow_valid_p, decode_valid_window):
2263 Now static, not extern.
2264 * data.c (Qinterval): Remove; unused.
2265 (syms_of_data): Do not define 'interval'.
2266 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
2267 * window.h (decode_valid_window):
2270 * character.c, charset.c, chartab.c: Use bool for booleans.
2271 * character.c (lisp_string_width, string_count_byte8)
2272 (string_escape_byte8):
2273 * charset.c (charset_map_loaded, load_charset_map, read_hex):
2274 (load_charset_map_from_file, map_charset_chars)
2275 (Fdefine_charset_internal, define_charset_internal)
2276 (Fdeclare_equiv_charset, find_charsets_in_text)
2277 (Ffind_charset_region, char_charset, Fiso_charset):
2278 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
2279 (sub_char_table_set, sub_char_table_set_range)
2280 (char_table_set_range, optimize_sub_char_table)
2281 (map_sub_char_table):
2282 Use bool for boolean.
2283 * character.c (str_to_unibyte): Omit last boolean argument; it was
2284 always 0. All callers changed.
2285 * character.h, charset.h: Adjust to match previous changes.
2286 * character.h (char_printable_p): Remove decl of nonexistent function.
2287 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
2288 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
2289 are all boolean, so make them single-bit bitfields.
2291 * lisp.h (ASET): Remove attempt to detect side effects.
2292 It was meant to be temporary and it often doesn't work,
2293 because when IDX has side effects the behavior of IDX==IDX
2294 is undefined. See Stefan Monnier in
2295 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
2297 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
2299 * lisp.h (functionp): New function (extracted from Ffunctionp).
2300 (FUNCTIONP): Use it.
2301 * eval.c (Ffunctionp): Use it.
2303 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
2305 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
2306 as that's faster and simpler than static storage. Don't bother
2307 with the g_main_context_query overhead if g_main_context_pending
2308 says no events are pending.
2309 (gfds, gfds_size): Remove these static vars.
2310 (xgselect_initialize): Remove; no longer needed.
2311 All uses and decls removed.
2313 * emacs.c (fatal_error_signal_hook): Remove.
2314 All uses removed. This leftover from old code was always 0.
2316 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
2317 * casefiddle.c (casify_object, casify_region):
2318 * casetab.c (set_case_table):
2319 * category.c, category.h (word_boundary_p):
2320 * category.h (CHAR_HAS_CATEGORY):
2321 Use bool for booleans, instead of int.
2323 2012-08-25 Eli Zaretskii <eliz@gnu.org>
2325 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
2327 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
2329 On assertion failure, print backtrace if available.
2330 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
2331 (die) [ENABLE_CHECKING]: Print a backtrace if available.
2332 * Makefile.in (LIB_EXECINFO): New macro.
2335 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
2336 * bytecode.c (exec_byte_code):
2337 * callint.c (check_mark, Fcall_interactively):
2338 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
2339 (getenv_internal, sync_process_alive, call_process_exited):
2340 * lisp.h (USE_SAFE_ALLOCA):
2341 Use bool for booleans, instead of int.
2342 * lisp.h, process.h: Adjust prototypes to match above changes.
2343 * callint.c (Fcall_interactively): Don't assume the mark's
2344 offset fits in 'int'.
2346 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
2348 * buffer.c, buffer.h: Use bool for boolean.
2349 * buffer.c (reset_buffer_local_variables)
2350 (buffer_lisp_local_variables, Fset_buffer_modified_p)
2351 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
2352 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
2353 (overlay_touches_p, overlay_strings, Foverlay_put)
2354 (report_overlay_modification, call_overlay_mod_hooks):
2355 (mmap_enlarge, mmap_set_vars):
2356 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
2357 Use bool for booleans, instead of int.
2358 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
2359 since the 1-or-0 return value is always ignored anyway.
2360 (mmap_initialized_p):
2361 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
2362 * buffer.h, lisp.h: Adjust prototypes to match above changes.
2364 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
2366 * bidi.c: Use bool for boolean.
2367 This is a bit more readable, and makes the text segment of bidi.o
2368 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
2369 Presumably it's faster too.
2370 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
2372 (bidi_cache_find_level_change, bidi_cache_iterator_state)
2373 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
2374 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
2375 (bidi_explicit_dir_char, bidi_level_of_next_char)
2376 (bidi_find_other_level_edge, bidi_move_to_visually_next):
2377 Use bool for booleans, instead of int.
2378 * dispextern.h (bidi_init_it, bidi_paragraph_init)
2379 (bidi_unshelve_cache): Adjust decls to match code.
2381 2012-08-23 Martin Rudalics <rudalics@gmx.at>
2383 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
2386 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
2388 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
2389 * atimer.h: Include <stdbool.h>.
2391 2012-08-22 Dan Nicolaescu <dann@gnu.org>
2393 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
2394 compile time tests instead of run time tests on systems that do
2396 (FRAME_MAC_P): Remove leftover from deleted code.
2397 * frame.c (syms_of_frame): Remove leftover from deleted code.
2399 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
2401 * nsterm.m (insertText:): Don't clear modifiers if code is space.
2403 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
2405 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
2406 Otherwise, the compiler complains about (A?B:C) where B is void
2407 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
2408 (fontset_add): Return void, for FONTSET_ADD.
2410 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2412 * alloc.c: Use bool for booleans.
2413 (gc_in_progress, abort_on_gc)
2414 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
2415 (dont_register_blocks) [GC_MALLOC_CHECK]:
2416 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
2417 (check_string_bytes, make_specified_string, memory_full)
2418 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
2419 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
2420 (mark_stack, valid_pointer_p, make_pure_string)
2421 (Fgarbage_collect, survives_gc_p, gc_sweep):
2422 Use bool for booleans, instead of int.
2423 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
2424 Remove unused local.
2425 * alloc.c (PURE_POINTER_P):
2426 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
2427 * editfns.c (Fformat):
2428 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
2430 * fns.c (sweep_weak_table):
2431 * lisp.h (suppress_checking, push_message, survives_gc_p)
2432 (make_pure_string, gc_in_progress, abort_on_gc):
2433 * lread.c (readchar, read1):
2434 * print.c (Fprin1_to_string):
2435 * xdisp.c (push_message):
2436 Use bool for booleans affected directly or indirectly by
2439 Make recently-introduced setters macros.
2440 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
2441 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
2442 (set_fontset_default, set_fontset_fallback): Rename from their
2443 upper-case counterparts, and make them functions rather than macros.
2444 This is more consistent with the other recently-introduced setters.
2445 These don't need to be inline, since they're local.
2447 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
2449 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
2450 the loop (Bug#12247).
2452 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2454 * lisp.h (vcopy): Use memcpy rather than our own loop.
2455 This fixes a performance regression introduced by the recent
2456 addition of vcopy. This means 'vcopy' will need to be modified
2457 for a copying collector, but that's OK. Also, tighten the
2458 checking in the assertion.
2460 2012-08-21 Eli Zaretskii <eliz@gnu.org>
2462 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
2463 components for RTL text (Bug#11860). Adjust X-OFFSET of each
2464 non-base glyph for the width of the base character, according to
2465 what x_draw_composite_glyph_string_foreground expects.
2466 Generate WADJUST value according to composition_gstring_width's
2467 expectations, to produce correct width of the composed character.
2468 Reverse the sign of the DU offset produced by ScriptPlace.
2470 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2472 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
2474 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2476 Avoid direct writes to contents member of struct Lisp_Vector.
2477 * lisp.h (vcopy): New function to copy data into vector.
2478 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
2479 * fns.c (Ffillarray): Use ASET.
2480 * keyboard.c (timer_check_2): Use AREF and ASET.
2481 (append_tool_bar_item, Frecent_keys): Use vcopy.
2482 * lread.c (read_vector): Use ASET.
2483 * msdos.c (Frecent_doskeys): Use vcopy.
2484 * xface.c (Finternal_copy_lisp_face): Use vcopy.
2485 (Finternal_merge_in_global_face): Use ASET and vcopy.
2486 * xfont.c (xfont_list_pattern): Likewise.
2488 2012-08-21 Martin Rudalics <rudalics@gmx.at>
2490 * window.c (Fwindow_point): For the selected window always return
2491 the position of its buffer's point.
2492 (Fset_window_point): For the selected window always go in its
2493 buffer to the specified position.
2495 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2497 Setter macros for fontsets.
2498 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
2499 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
2500 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
2503 2012-08-20 Glenn Morris <rgm@gnu.org>
2505 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
2506 Don't assume that `ln -f' works.
2508 2012-08-20 Eli Zaretskii <eliz@gnu.org>
2510 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
2511 and later about non-assignments with no effect. See discussion at
2512 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
2515 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2517 Inline setter functions for Lisp_Objects slots of struct specbinding.
2518 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
2521 2012-08-20 Martin Rudalics <rudalics@gmx.at>
2523 * window.c (select_window): Always make selected window's buffer
2526 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2528 Use AREF and ASET for docstrings of category tables.
2529 * category.h (CATEGORY_DOCSTRING): Use AREF.
2530 (SET_CATEGORY_DOCSTRING): Use ASET.
2531 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
2533 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2535 Inline setter functions for hash table members.
2536 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
2537 (set_hash_hash, set_hash_index): Rename with _slot suffix.
2538 (set_hash_key_and_value, set_hash_index, set_hash_next)
2539 (set_hash_hash): New functions.
2540 * charset.c, fns.c: Adjust users.
2542 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2544 Inline getter and setter functions for per-buffer values.
2545 * buffer.h (per_buffer_default, set_per_buffer_default)
2546 (per_buffer_value, set_per_buffer_value): New functions.
2547 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
2548 * buffer.c, data.c: Adjust users.
2550 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
2552 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
2554 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
2556 Rely on <config.h> + <unistd.h> to declare 'environ',
2557 as gnulib does this if the system doesn't.
2558 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
2559 Remove declaration. MS-Windows declares it on stdlib.h which is
2560 included by conf_post.h.
2561 * emacs.c (environ) [DOUG_LEA_MALLOC]:
2562 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
2563 * vm-limit.c: Include <unistd.h>, for 'environ'.
2565 * unexaix.c, unexcoff.c: Include "mem-limits.h".
2566 (start_of_data): Remove decl; mem-limits.h provides it.
2568 * xdisp.c (handle_invisible_prop): Make it a bit faster
2569 and avoid a gcc -Wmaybe-uninitialized diagnostic.
2571 2012-08-19 Chong Yidong <cyd@gnu.org>
2573 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
2576 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
2578 * .gdbinit: Use call instead of set when calling a function in the
2581 * data.c (set_internal): Don't use set_blv_found.
2582 (Fkill_local_variable): Likewise.
2584 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
2586 * nsfont.m (ns_ascii_average_width): Ensure the string
2587 ascii_printable is initialized with a null-terminated character
2588 array. Otherwise, it can contain undesired extra characters.
2590 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
2592 port new setting code to Sun C 5.8 2005/10/13
2593 * chartab.c, lisp.h (char_table_set, char_table_set_range):
2594 Return void, not Lisp_Object. Otherwise, the compiler
2595 complains about (A?B:C) where B is void and C is Lisp_Object
2596 when compiling CHAR_TABLE_SET, due to the recent change to
2597 the API of sub_char_table_set_contents.
2599 2012-08-18 Chong Yidong <cyd@gnu.org>
2601 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
2602 for the string case (Bug#3874).
2604 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
2606 * buffer.h (BSET): Remove (Bug#12215).
2607 Replace all uses with calls to new setter functions.

2636 * syntax.c (bset_syntax_table):
2637 New setter functions.
2639 * process.h (PSET): Remove (Bug#12215).
2640 Replace all uses with calls to new setter functions.

2644 (pset_gnutls_cred_type) [HAVE_GNUTLS]: New setter function.
2645 * process.c (PROCESS_INLINE):

2651 (pset_plist, pset_sentinel, pset_status, pset_tty_name)
2652 (pset_type, pset_write_queue): New setter functions.
2654 * window.h (WSET): Remove (Bug#12215).
2655 Replace all uses with calls to new setter functions.
2656 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
2657 (WINDOW_INLINE): New macro.

3434 value of EMACSLOADPATH, as it is no longer needed.
3435 (check_windows_init_file): Now external, not static.

3441 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

3486 * alloc.c (record_xmalloc): New function.
3487 * lisp.h (record_xmalloc): New decl.
3488 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
3489 more like a function. This is because the pointer cast is not
3490 needed. All uses changed.
3491 * print.c (print_string, print_error_message): Avoid length recalc.
3493 Improve fix for macroexp crash with debugging (Bug#12118).
3494 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
3495 ARRAY_MARK_FLAG when checking subscripts, because ASET is

3498 (gc_aset): New function, which is like ASET but can be
3499 used in the garbage collector.

3528 with addition of handling of symlinks and support for 'lstat'.
3529 If possible, get file's attributes and security information by
3530 handle, not by name. Produce S_IFLNK bit for symlinks, when
3531 called from 'lstat'.
3532 (stat, lstat): New functions, call 'stat_worker'.
3533 (symlink, readlink, careadlinkat): Rewritten to create and resolve
3534 symlinks when the underlying filesystem supports them.
3536 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
3538 Fix macroexp crash on Windows with debugging (Bug#12118).
3539 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
3540 checking subscripts; problem introduced with the recent
3541 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
3542 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
3543 since it's used in non-static inline functions now.
3545 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
3546 Don't assume buffer size fits in 'int'. Remove unused local.

4013 * alloc.c (listn): Fix the order the arguments are consed onto the
4016 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
4017 enumeration constants, as PURE and HEAP are too general, and clash
4018 with other headers and sources, such as gmalloc.c and the
4019 MS-Windows system headers. All users changed.
4021 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
4023 Revert last save_excursion_save and save_excursion_restore changes.
4024 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

4034 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
4036 Improve GDB symbol export (Bug#12036).
4037 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
4038 arms of an 'if', not using conditional expressions; otherwise GDB
4039 complains about the types in the unevaluated arm when the argument
4040 is an integer literal.
4041 (xgetint): Simplify expression.
4042 * alloc.c (gdb_make_enums_visible): New constant. This ports to
4043 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
4044 Zaretskii in <http://bugs.gnu.org/12036#13>.
4045 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
4046 needed now that we have gdb_make_enums_visible.
4047 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
4048 (enum enum_USE_LSB_TAG):
4049 New enum types, packaging up enums that need to be exported to GDB.
4051 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
4053 Utility function to make a list from specified amount of objects.

4055 (listn): New prototype.
4056 * alloc.c (listn): New function.

4067 * xdisp.c (syms_of_xdisp): Likewise.
4068 * xfns.c (syms_of_xfns): Likewise.
4070 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
4072 Fast save_excursion_save and save_excursion_restore.
4073 * lisp.h (struct Lisp_Excursion): New data type.
4074 (PVEC_EXCURSION): New pseudovector type.
4075 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
4076 to deal with it. Adjust comments.
4077 (init_marker, attach_marker): New prototype.
4078 (unchain_marker): Adjust prototype.

4087 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
4089 Fix export of symbols to GDB (Bug#12036).
4090 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
4091 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
4092 emacs.c, as this is a more-suitable home. Had this been done earlier
4093 the fix for 12036 would have avoided some of the problems noted in
4094 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
4095 would have been more obvious.
4096 * emacs.c: Do not include <verify.h>; no longer needed.
4097 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
4098 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
4099 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
4100 Remove; now done in lisp.h.
4101 * lisp.h (PUBLISH_TO_GDB): New macro.
4102 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
4103 (DATA_SEG_BITS): Use it.
4104 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
4105 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
4106 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
4107 not be usable in #if. This simplifies things.
4109 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
4111 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
4113 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
4115 Simplify export of symbols to GDB (Bug#12036).
4116 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
4117 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
4118 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
4119 Adjust to changes in lisp.h and emacs.c, by using
4120 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
4121 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
4122 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
4123 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
4124 instead of gdb_valbits.
4125 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
4126 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
4127 instead of gdb_array_mark_flag.
4128 (xboolvector): Get size from $->size, not $->header.size.
4129 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
4130 (xreload, hook-run, hookpost-run): Remove.
4131 * emacs.c: Include <verify.h>.
4132 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
4133 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
4135 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
4136 (gdb_USE_LSB_TAG): New enum constants.
4137 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
4138 Also define these as enum constants, so they're visible to GDB.
4139 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
4140 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
4141 as constants, so they're visible to GDB.
4142 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
4143 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
4144 Now enum constants, not macros, so they're visible to GDB.
4145 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
4146 more convenient now. All uses changed.
4147 (VALMASK) [USE_LSB_TAG]: Also define in this case.
4148 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
4150 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

4155 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
4157 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
4158 add argument, tune behavior, and adjust all callers.
4160 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
4162 Use typedef for EMACS_INT, EMACS_UINT.
4163 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
4164 than macros. This simplifies debugging in the usual case, since
4165 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
4166 and it allows expressions involving EMACS_INT casts.
4167 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
4169 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

4177 that FOCUS-FRAME can be omitted.
4179 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
4181 Adjust buffer text indirection counters at the end of Fkill_buffer.
4182 * buffer.c (Fkill_buffer): Adjust indirection counters when the
4183 buffer is definitely dead. This should really fix an issue reported
4184 by Christoph Scholtes again. (Bug#12007).
4185 (init_buffer_once): Initialize indirection counters of
4186 buffer_defaults and buffer_local_symbols (for sanity and safety).
4188 2012-07-24 Eli Zaretskii <eliz@gnu.org>
4190 * xdisp.c (init_iterator): Don't compute dimensions of truncation
4191 and continuation glyphs on tooltip frames, leave them at zero.
4192 Avoids continued lines in tooltips. (Bug#11832)
4194 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
4196 Simplify copy_overlay.
4197 * buffer.c (copy_overlay): Simplify. Use build_marker.

4219 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
4221 Swap buffer text indirection counters in Fbuffer_swap_text.
4222 * buffer.c (Fbuffer_swap_text): Swap indirections too.
4223 This avoids crash reported by Christoph Scholtes at
4224 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
4226 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
4228 * nsmenu.m (Popdown_data): New struct.
4229 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
4231 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.

4233 and autorelease them. Also autorelease img and matrix (Bug#12005).
4234 (dealloc): Remove (Bug#12005).

4251 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
4253 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
4254 as it's limited by the amount of memory, not by INT_MAX.
4256 2012-07-21 Eli Zaretskii <eliz@gnu.org>
4258 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
4259 in special-event-map. See the discussion at

4318 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
4319 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
4320 Adjust users accordingly.
4321 * font.h (font_open_by_name): Adjust prototype.
4323 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>

4339 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
4340 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
4341 'for_each_per_buffer_object_at'.
4342 All uses changed. It's better to use upper-case for macros that
4343 cannot be implemented as functions, to give the reader a clue
4344 that they're special.
4346 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
4348 * alloc.c (Fgarbage_collect): Tweak docstring.

4389 * intervals.c (merge_interval_right, merge_interval_left):
4390 Do not zero out this interval if it is absorbed by its children,
4391 as this interval's total length doesn't change in that case. See
4392 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
4394 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
4396 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
4397 when invoking (make-bool-vector N t) and N is a positive
4398 multiple of 8 -- the last 8 bits were mistakenly cleared.
4400 Remove some struct layout assumptions in bool vectors.
4401 * alloc.c (bool_header_size): New constant.
4402 (header_size, word_size): Move earlier, as they're now used earlier.

4404 (Fmake_bool_vector, sweep_vectors): Don't assume that there is no
4405 padding before the data member of a bool vector.
4406 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
4407 than doing the check by hand with an abort ().
4409 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
4411 * eval.c (Fdefvar): Don't check constants since we only set the var if
4412 it's not yet defined anyway (bug#11904).
4414 * lisp.h (last_undo_boundary): Declare new var.
4415 * keyboard.c (command_loop_1): Set it.
4416 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
4417 were auto-added by the command loop (bug#11774).
4419 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
4421 * w32font.c (Qsymbol): Remove local definition.

4910 2012-07-11 Glenn Morris <rgm@gnu.org>
4912 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
4913 since nothing has defined it on these platforms.
4915 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/gnu-linux.h:
4916 * s/irix6-5.h: Move SIGNALS_VIA_CHARACTERS to configure.

4920 Move CLASH_DETECTION to configure.
4922 * s/gnu.h: Remove file, which is now empty.
4924 * s/gnu.h, s/gnu-linux.h:
4925 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
4927 2012-07-11 John Wiegley <johnw@newartisans.com>
4929 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
4930 function attribute, so we only use it if it exists in the
4933 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
4935 Avoid call to strlen in fast_c_string_match_ignore_case.
4936 * search.c (fast_c_string_match_ignore_case): Change to use
4937 length argument. Adjust users accordingly.
4938 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
4940 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

4981 Remove "#define unix" that is no longer needed (Bug#11905).
4982 * s/aix4-2.h (unix): Remove; no longer needed.
4984 EMACS_TIME simplification (Bug#11875).
4985 This replaces macros (which typically do not work in GDB)
4986 with functions, typedefs and enums, making the code easier to debug.
4987 The functional style also makes code easier to read and maintain.
4988 * systime.h: Include <sys/time.h> on all hosts, not just if
4989 WINDOWSNT, since 'struct timeval' is needed in general.
4990 (EMACS_TIME): Now a typedef, not a macro.
4991 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
4993 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

4996 (EMACS_TIME_LE): Now functions, not macros.
4997 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
4998 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
4999 which are not functions. All uses rewritten to use:
5000 (make_emacs_time): New function.
5001 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
5002 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
5003 not functions. All uses rewritten to use the following, respectively:
5004 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
5005 (add_emacs_time, sub_emacs_time): New functions.
5006 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
5007 * fileio.c (Fcopy_file):
5008 * xterm.c (XTflash): Get the current time closer to when it's used.
5009 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

5017 * gtkutil.c (get_utf8_string):
5019 * nsmenu.m (ns_update_menubar):
5020 * regex.c (regerror):
5021 Prefer memcpy to strncpy and strncat when either will do.
5022 * fileio.c (Fsubstitute_in_file_name):
5023 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
5024 (menu_separator_name_p):
5025 * nsmenu.m (ns_update_menubar):
5026 Prefer memcmp to strncmp when either will do.
5027 * nsterm.m: Include <ftoastr.h>.
5029 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
5030 Prefer snprintf to strncpy.
5031 * nsterm.m (ns_term_init):
5032 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
5033 * nsterm.m (ns_term_init):
5034 Avoid the need for strncpy, by using build_string or
5035 make_unibyte_string directly. Use dtoastr, not snprintf.
5036 * process.c (Fmake_network_process): Diagnose service names that
5037 are too long, rather than silently truncating them or creating
5038 non-null-terminated names.
5039 (Fnetwork_interface_info): Likewise, for interface names.
5040 * sysdep.c (system_process_attributes) [GNU_LINUX]:
5041 Prefer sprintf to strncat.
5042 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
5043 Prefer vsnprintf to vsprintf + strncpy.
5045 2012-07-10 Glenn Morris <rgm@gnu.org>
5047 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
5048 Clarify fallback case.
5050 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
5052 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
5053 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
5054 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
5055 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
5056 where argument type is known to be a Lisp_Cons.
5058 2012-07-10 Tom Tromey <tromey@redhat.com>
5060 * bytecode.c (BYTE_CODE_THREADED): New macro.
5061 (BYTE_CODES): New macro. Replaces all old byte-code defines.

5068 Optimize pure C strings initialization.
5069 * lisp.h (make_pure_string): Fix prototype.
5070 (build_pure_c_string): New function, defined as static inline. This
5071 provides a better opportunity to optimize away calls to strlen when
5072 the function is called with compile-time constant argument.
5073 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
5074 argument, adjust users accordingly. Use build_pure_c_string where
5076 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
5077 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
5078 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
5080 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
5082 Avoid calls to strlen in miscellaneous functions.
5083 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
5084 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
5085 * lread.c (openp): Likewise.
5087 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
5089 Avoid calls to strlen in path processing functions.
5090 * fileio.c (file_name_as_directory): Add comment. Change to add
5091 srclen argument and return the length of result. Adjust users
5093 (directory_file_name): Fix comment. Change to add srclen argument,
5094 swap 1st and 2nd arguments to obey the common convention.
5095 Adjust users accordingly.
5096 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
5098 2012-07-10 Glenn Morris <rgm@gnu.org>
5100 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

5105 * s/gnu.h (DATA_START): Move definitions to configure.
5107 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
5108 We include usg5-4-common.h, which defines them both.
5110 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
5111 O_RDONLY already includes it).
5113 Stop ns builds setting the EMACSLOADPATH environment variable.
5114 * nsterm.m (ns_load_path): Rename from ns_init_paths.
5115 Now it does not set EMACSLOADPATH, just returns the load-path string.
5116 * nsterm.h: Update accordingly.
5117 * lread.c [HAVE_NS]: Include nsterm.h.
5118 (init_lread) [HAVE_NS]: Use ns_load_path.
5119 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
5121 2012-07-09 Glenn Morris <rgm@gnu.org>
5123 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
5124 since the included bsd-common.h does so.
5126 Stop ns builds setting the EMACSPATH environment variable.
5127 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
5128 (ns_init_paths): Do not set EMACSPATH.
5129 * nsterm.h (ns_exec_path): Add it.
5130 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
5133 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
5135 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
5137 * process.c (wait_reading_process_output): 'waitchannels' was unset
5138 when read_kbd || !NILP (wait_for_cell); fix this.
5140 Add GCC-style 'const' attribute to functions that can use it.
5141 * character.h (char_resolve_modifier_mask):
5142 * keyboard.h (make_ctrl_char):
5143 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
5144 (init_character_once, next_almost_prime, init_fns, init_image)
5145 (flush_pending_output, init_sound):
5146 * mem-limits.h (start_of_data):

5150 Declare the dummy function with ATTRIBUTE_CONST.
5151 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
5152 Add decls with ATTRIBUTE_CONST.
5154 Minor improvements to make_formatted_string.
5155 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
5156 where int is good enough, as vsprintf returns an int.
5157 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
5159 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
5161 Use make_formatted_string to avoid double length calculation.
5162 * lisp.h (make_formatted_string): New prototype.

5168 * frame.c (make_terminal_frame, set_term_frame_name)
5169 (x_report_frame_params): Likewise.
5170 * image.c (gs_load): Likewise.
5171 * minibuf.c (get_minibuffer): Likewise.

5186 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
5188 Move marker debugging code under MARKER_DEBUG.
5189 * marker.c (MARKER_DEBUG): Move marker debugging code under
5190 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
5191 for bootstrap with --enable-checking (~3x slowdown reported
5192 by Juanma Barranquero <lekktu@gmail.com>).
5193 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
5195 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
5197 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
5198 See <http://bugs.gnu.org/11825#29>.
5200 2012-07-08 Eli Zaretskii <eliz@gnu.org>
5202 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
5203 has no font, use the frame's font. (Bug#11813)
5204 (display_line): Add commentary about displaying truncation glyphs
5206 (produce_special_glyphs): Move here from term.c.
5208 * term.c (produce_special_glyphs): Move to xdisp.c.
5210 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
5213 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
5215 * xdisp.c (display_line): Avoid warning about implicit declaration
5218 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
5220 * lisp.h: Remove empty conditional.
5222 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
5224 * lread.c (load_path_check): Now static.
5226 Fix some minor --with-ns problems found by static checking.
5227 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
5228 (x_set_font) [!HAVE_X_WINDOWS]:
5229 * image.c (xpm_load_image) [HAVE_NS]:
5230 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
5231 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
5232 Remove unused local.
5233 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
5234 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
5235 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
5236 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
5237 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
5238 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
5239 Fix pointer signedness problem.
5240 * xfaces.c (FRAME_X_FONT_TABLE):
5241 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
5243 2012-07-07 Glenn Morris <rgm@gnu.org>
5245 * lread.c (load_path_check): New function, split from init_lread.
5246 (init_lread): Reorganize. Motivation:
5247 If EMACSLOADPATH is set, check/warn about that rather than the
5248 defaults, which we are not going to use. Hence we can remove
5249 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
5250 Don't warn if site-lisp directories are missing.
5251 If not installed, start from a blank load-path, since
5252 PATH_LOADSEARCH refers to the eventual installation directories.
5254 2012-07-07 Eli Zaretskii <eliz@gnu.org>
5256 Support truncation and continuation glyphs on GUI frames, when
5257 fringes are disabled. (Bug#11832)
5258 * xdisp.c (init_iterator): Get dimensions of truncation and
5259 continuation glyphs even if on GUI frames.
5260 Adjust it->last_visible_x on GUI frames when the left or right fringes,
5261 or both, are absent.
5262 (start_display, move_it_in_display_line_to): Handle the case of a
5263 GUI frame without a fringe to display continuation or truncation
5265 (insert_left_trunc_glyphs): Support GUI frames: make sure
5266 truncation glyphs overwrite enough glyphs from the current line to
5267 have sufficient space in pixels.
5268 (display_line): Support truncation and continuation glyphs on GUI
5269 frames. If some spare pixels are left on the line after inserting
5270 the truncation glyphs, fill that space with a stretch glyph of a
5271 suitably computed width.
5273 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
5274 produce_glyphs, to support GUI sessions.
5276 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
5278 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
5280 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
5282 Do not require float-time's arg to fit in time_t (Bug#11825).
5283 This works better on hosts where time_t is unsigned, and where
5284 float-time is applied to the (negative) difference between two times.
5285 * editfns.c (decode_time_components): Last arg is now double *,
5286 not int *, and means to store all the result as a double, without
5287 worrying about whether the seconds part fits in time_t.
5288 All callers changed.
5289 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
5290 All callers changed.
5291 (Ffloat_time): Do not fail merely because the specified time falls
5292 outside of time_t range.
5294 2012-07-07 Glenn Morris <rgm@gnu.org>
5296 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

5300 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
5302 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
5303 Update dependencies.
5305 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
5307 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5309 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
5310 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
5311 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
5312 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
5313 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
5314 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
5316 * xfont.c (compare_font_names): Redo to omit the need for casts.
5318 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
5320 * xfns.c (Fx_change_window_property): Doc fix.
5321 * w32fns.c (Fx_change_window_property): Doc fix.
5323 * w32fns.c (Fx_window_property): Accept the same arguments as the
5324 X Windows version. Doc fix.
5325 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
5327 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
5328 Eli Zaretskii <eliz@gnu.org>
5330 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
5331 Windows-specific code from nt/config.nt moved here.
5332 Obsolete settings removed.
5334 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5336 * process.c: Avoid unnecessary calls to gettime.
5337 (wait_reading_process_output): Don't get the time of day
5338 when gobbling data immediately and not waiting, as there's no need
5339 for it in that case. This removes a FIXME.
5341 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
5343 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
5344 is defined (Bug#11768).
5346 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5348 Fix marker debugging code.
5349 * marker.c (byte_char_debug_check): Do not perform the check
5350 if buffer is not multibyte.
5351 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
5352 Call byte_char_debug_check with correct arguments.
5354 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5356 Compile marker debugging code only if ENABLE_CHECKING is defined.
5357 * marker.c (byte_char_debug_check, count_markers):
5358 Use only if ENABLE_CHECKING is defined.
5359 (byte_debug_flag): Remove.
5360 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
5361 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
5363 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5365 Avoid code repetition in marker-related functions.
5366 * marker.c (attach_marker): New function.
5367 (Fset_marker, set_marker_restricted, set_marker_both)
5368 (set_marker_restricted_both): Use it.
5369 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
5370 Consistently rename charno to charpos.
5371 (marker_position): Add eassert.
5372 (marker_byte_position): Convert to eassert.
5374 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5376 Simplify list operations in unchain_overlay and unchain_marker.
5377 * buffer.c (unchain_overlay): Simplify. Add comment.
5378 * marker.c (unchain_marker): Simplify. Fix comments.
5380 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5382 Introduce fast path for the widely used marker operation.
5383 * alloc.c (build_marker): New function.
5384 * lisp.h (build_marker): New prototype.
5385 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
5386 * composite.c (autocmp_chars): Likewise.
5387 * editfns.c (buildmark): Remove.
5388 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
5389 (save_restriction_save): Use build_marker.
5390 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
5391 * window.c (save_window_save): Likewise.
5393 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

5396 to avoid redundant calls to unchain_overlay.
5397 * buffer.c (drop_overlay): New function.
5398 (delete_all_overlays, Fdelete_overlay): Use it.
5399 * minibuf.c (get_minibuffer): Fix comment.
5401 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5403 Port to OpenBSD 5.1 amd64.
5404 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
5405 This is needed for OpenBSD, and should be harmless on all BSD systems.
5406 Also, include <sys/sysctl.h>, as it should be available on all
5407 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
5408 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
5409 use p_pid member, not kp_proc.pid.
5411 2012-07-06 Glenn Morris <rgm@gnu.org>
5413 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
5415 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5417 More xmalloc and related cleanup.
5418 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

5425 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
5426 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
5428 Omit needless casts involving void * pointers and allocation.
5429 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
5430 as the former is more robust if P's type is changed.
5431 Prefer xzalloc to xmalloc + memset 0.
5432 Simplify malloc-or-realloc to realloc.
5433 Don't worry about xmalloc returning a null pointer.
5434 Prefer xstrdup to xmalloc + strcpy.
5435 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
5437 * keyboard.c (apply_modifiers_uncached): Prefer local array to
5438 alloca of a constant.
5440 2012-07-05 Eli Zaretskii <eliz@gnu.org>
5442 * xdisp.c (display_line): Fix horizontal pixel coordinates when
5443 hscroll is larger than the line width. Fixes long and futile
5444 looping inside extend_face_to_end_of_line (on a TTY) producing
5445 glyphs that are not needed and thrown away.
5447 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
5449 * marker.c (set_marker_restricted_both): Simplify by using
5452 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5454 * editfns.c (region_limit): Simplify by using clip_to_bounds.
5456 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
5458 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
5459 not defined (Bug#11768).
5460 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
5461 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
5462 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
5463 followed by gtk_box_set_homogeneous (Bug#11768).
5464 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
5465 (update_theme_scrollbar_width, xg_create_scroll_bar):
5466 Use gtk_scrollbar_new (Bug#11768).
5467 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
5468 (is_box_type): New function (Bug#11768).
5469 (xg_tool_item_stale_p): Call is_box_type.
5470 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
5471 with default display (Bug#11768).
5473 2012-07-05 Eli Zaretskii <eliz@gnu.org>
5475 * xdisp.c (window_hscroll_limited): New function.
5476 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
5477 coordinates when window's hscroll is set to insanely large
5480 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
5482 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
5483 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
5485 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
5488 * lisp.h (xzalloc): New prototype. Omit needless casts.
5489 * alloc.c (xzalloc): New function. Omit needless casts.
5490 * charset.c: Omit needless casts. Convert all calls to
5491 xmalloc with following memset to xzalloc.

5541 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5543 * fileio.c (time_error_value): Check the right error number.
5544 Problem reported by Troels Nielsen in
5545 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
5547 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5549 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
5550 This should be fixed in a better way; see Eli Zaretskii in
5551 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
5552 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
5554 * fileio.c (time_error_value): Rename from special_mtime.
5555 The old name's problems were noted by Eli Zaretskii in
5556 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
5558 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
5559 This variable's comment says Emacs needs at least one GDB-visible
5560 symbol of type enum pvec_type, to work around GDB problems.
5561 The symbol's value doesn't matter.
5563 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
5564 that causes compilation to fail on pre-C99 compilers.
5566 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
5568 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
5569 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
5571 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5573 * buffer.c (init_buffer_once): Fix initialization of
5574 headers for buffer_defaults and buffer_local_symbols.
5575 Reported by Juanma Barranquero <lekktu@gmail.com>.
5577 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
5579 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
5580 * lisp.h (enum pvec_type): Use fewer bits.
5581 (PSEUDOVECTOR_SIZE_BITS): New constant.
5582 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
5583 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
5584 change in pvec_type.
5585 (PSEUDOVECTOR_TYPEP): New macro.
5586 (TYPED_PSEUDOVECTORP): Use it.
5587 * fns.c (internal_equal): Adapt code to extract pvectype.
5588 * emacs.c (gdb_pvec_type): Update type.
5589 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
5590 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
5591 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
5592 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
5593 (sweep_vectors): Use it. Use local var `total_bytes' instead of
5594 abusing vector->header.next.nbytes.
5595 (live_vector_p): Use PVEC_TYPE.
5596 (mark_object): Adapt code to extract pvectype. Use switch.
5598 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5600 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
5601 Tighten new eassert a bit.
5603 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5605 Fix compilation with --enable-gcc-warnings and -O1
5607 * doprnt.c (doprnt): Change type of tem to int, initialize
5608 to avoid compiler warning. Add eassert.
5609 * search.c (simple_search): Initialize match_byte to avoid
5610 compiler warning. Add eassert.
5612 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5614 Avoid weird behavior with large horizontal scrolls.
5615 Without this change, for example, large hscroll values would
5616 mess up Emacs's display on Fedora 15 x86, presumably due to
5617 overflows in int calculations in the display code.
5618 Also, if buffers had long lines, Emacs would freeze.
5619 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
5620 (set_window_hscroll): New function, containing the old guts of
5621 Fset_window_hscroll. Return the clipped value.
5622 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
5623 This avoids the need to check against PTRDIFF_MAX.
5625 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
5627 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5629 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
5631 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5633 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
5634 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
5635 since GCC 4.4.6 issues a bogus warning for them.
5637 Fix bugs in file timestamp newness comparisons.
5638 * fileio.c (Ffile_newer_than_file_p):
5639 * lread.c (Fload): Use full timestamp resolution of files,
5640 not just the 1-second resolution, so that files that are only
5641 slightly newer still count as newer.
5642 * fileio.c (Ffile_newer_than_file_p): Don't assume file
5643 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
5645 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
5647 * fileio.c: Improve handling of file time marker. (Bug#11852)
5648 (special_mtime): New function.
5649 (Finsert_file_contents, Fverify_visited_file_modtime):
5650 Use it to set special mtime values consistently.
5652 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
5654 * fileio.c (Finsert_file_contents): Properly handle st_mtime
5655 marker for non-existing file. (Bug#11852)
5657 2012-07-03 Glenn Morris <rgm@gnu.org>
5659 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
5660 and did not make it into globals.h).
5662 2012-07-03 Tom Tromey <tromey@redhat.com>
5664 * window.c (Fset_window_margins, Fset_window_fringes)
5665 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
5666 * textprop.c (Fprevious_property_change): No longer static.
5667 * syntax.c (Fsyntax_table_p): No longer static.
5668 * process.c (Fget_process, Fprocess_datagram_address): No longer

5682 * dired.c (Ffile_attributes): No longer static.
5683 * composite.c (Fcomposition_get_gstring): No longer static.
5684 * callproc.c (Fgetenv_internal): No longer static.
5686 * ccl.h: Remove EXFUNs.
5687 * buffer.h: Remove EXFUNs.
5688 * dispextern.h: Remove EXFUNs.
5689 * intervals.h: Remove EXFUNs.
5690 * fontset.h: Remove EXFUN.
5691 * font.h: Remove EXFUNs.
5692 * dosfns.c (system_process_attributes): Remove EXFUN.
5693 * keymap.h: Remove EXFUNs.
5694 * lisp.h: Remove EXFUNs.
5695 * w32term.h: Remove EXFUNs.
5696 * window.h: Remove EXFUNs.
5697 * xsettings.h: Remove EXFUN.
5698 * xterm.h: Remove EXFUN.
5700 2012-07-03 Glenn Morris <rgm@gnu.org>
5702 * lisp.h (Frandom): Make it visible to C.
5703 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
5704 buffer for invisible buffers. (Bug#1229)
5706 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5708 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
5709 values which aren't power of 2.
5710 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
5711 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
5714 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
5716 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
5718 * alloc.c (mark_object): Revert part of last patch to use `switch'.
5720 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5722 * alloc.c (allocate_vector_block): Remove redundant
5723 calls to mallopt if DOUG_LEA_MALLOC is defined.
5724 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
5725 avoid calls to mallopt if zero_vector is returned.
5727 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5729 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
5730 is enabled, avoid dereferencing NULL current_sblock if
5733 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5735 Cleanup basic buffer management.
5736 * buffer.h (struct buffer): Change layout to use generic vector
5737 marking code. Fix some comments. Change type of 'clip_changed'
5738 to bitfield. Remove unused #ifndef old.
5739 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
5740 (GET_OVERLAYS_AT): Fix indentation.
5741 (for_each_per_buffer_object_at): New macro.
5742 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
5743 (Fbuffer_local_variables): Use it.
5744 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
5745 * alloc.c (allocate_buffer): Adjust to match new layout of
5746 struct buffer. Fix comment.
5747 (mark_overlay): New function.
5748 (mark_buffer): Use it. Use mark_vectorlike to mark normal
5749 Lisp area of struct buffer.
5750 (mark_object): Use it. Adjust marking of misc objects
5751 and related comments.
5753 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
5755 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
5756 wrapper that is not needed because the wrapped code is a no-op (zero
5757 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
5758 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
5760 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
5762 * alloc.c (mark_buffer): Simplify. Remove prototype.
5763 (mark_object): Add comment. Reorganize marking of vector-like
5764 objects. Use CHECK_LIVE for all vector-like objects except buffers
5765 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
5766 Avoid redundant calls to mark_vectorlike for bool vectors.
5768 2012-06-30 Glenn Morris <rgm@gnu.org>
5770 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
5772 * epaths.in (PATH_SITELOADSEARCH): New.
5773 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
5774 This is rather than relying on --enable-locallisppath elements
5775 having "site-lisp" in their names. (Bug#10208#25, 11658)
5777 2012-06-30 Eli Zaretskii <eliz@gnu.org>
5779 * w32proc.c (sys_select): Accept and ignore one more argument.
5781 * w32.c (emacs_gnutls_pull): Call select with one more argument.
5783 * sysselect.h [DOS_NT]: Don't include sys/select.h.
5784 (pselect) [!MS_DOS]: Redirect to sys_select.
5786 * sysdep.c: Don't include dos.h and dosfns.h.
5788 * process.c (sys_select):
5789 * msdos.c (sys_select): Accept one more argument and ignore it.
5791 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
5792 adapt data types and code to that.
5795 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
5796 which clashes with the gnulib function of the same name.
5798 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
5800 * font.c (font_style_to_value, font_style_symbolic)
5801 (font_prop_validate_style): Add type checks for values in
5804 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
5806 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
5809 2012-06-29 Eli Zaretskii <eliz@gnu.org>
5811 * xdisp.c (try_window_id): Undo last change.
5813 * w32.c (getwd): Adjust commentary about startup_dir.
5814 (init_environment): Always call sys_access, even in non-MSVC
5815 builds. Don't chdir to the directory of the Emacs executable.
5816 This undoes code from 1997 which was justified by the need to
5817 "avoid conflicts when removing and renaming directories". But its
5818 downside was that every relative file name was being interpreted
5819 relative to the directory of the Emacs executable, which can never
5820 be TRT. In particular, it broke sys_access when called with
5821 relative file names.
5822 (sys_access): Map GetLastError to errno.
5824 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

6014 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
6016 Use sprintf return value instead of invoking strlen on result.
6017 In the old days this wasn't portable, since some sprintf
6018 implementations returned char *. But they died out years ago and
6019 Emacs already assumes sprintf returns int.
6020 Similarly for float_to_string.
6021 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

6028 * xfns.c (syms_of_xfns):
6029 Use sprintf or float_to_string result to avoid need to call strlen.
6030 * data.c (Fnumber_to_string):
6031 Use make_unibyte_string, since the string must be ASCII.
6032 * lisp.h, print.c (float_to_string): Now returns int length.
6033 * term.c (produce_glyphless_glyph):
6034 Use sprintf result rather than recomputing it.
6036 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
6037 * Makefile.in (ALL_CFLAGS):
6038 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

6067 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
6069 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
6070 `const char *' to `char *' to avoid compiler warning.
6072 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
6074 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
6075 instead of truncating it to 63 (admittedly a generous limit).
6077 * process.c: Fix spelling and caps in comments.
6079 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>

6134 * dispnew.c (Fsleep_for, sit_for):
6135 * keyboard.c (kbd_buffer_get_event):
6136 * process.c (Faccept_process_output):
6137 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
6138 This improves on the previous patch, which introduced a bug
6139 when time_t is unsigned and as wide as intmax_t.
6140 See <http://bugs.gnu.org/9000#51>.
6142 2012-06-23 Eli Zaretskii <eliz@gnu.org>

6159 Privately reported by Herbert J. Skuhra.
6160 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.

6205 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
6207 Support higher-resolution time stamps (Bug#9000).
6208 The time stamps are only nanosecond-resolution at the C level,
6209 since that's the best that any real-world system supports now.
6210 But they are picosecond-resolution at the Lisp level, as that's
6211 easy, and leaves room for future OS improvements.
6213 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
6216 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
6217 Don't get current time unless it's needed.
6219 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
6220 now provides it if it's absent.
6221 (start_atimer): Port to higher-res time stamps.
6222 Check for time stamp overflow. Don't get current time more
6223 often than is needed.
6225 * buffer.h (struct buffer): Buffer modtime now has high resolution.
6226 Include systime.h, not time.h.
6227 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
6229 * dired.c: Include stat-time.h.
6230 (Ffile-attributes): File times now have higher resolution.
6232 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
6233 (struct image): Timestamp now has higher resolution.
6235 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
6236 has at least microseconds now. All uses removed.
6237 (update_frame, update_single_window, update_window, update_frame_1)
6238 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
6239 (duration_to_sec_usec): Remove; no longer needed.
6241 * editfns.c (time_overflow): Now extern.
6242 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
6243 (float-time, Fformat_time_string, Fcurrent_time_string)

6247 (decode_time_components, lisp_seconds_argument): New functions.
6248 (make_time): Now static.
6249 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
6250 Report an error if the time is invalid, rather than having the caller
6253 * fileio.c: Include <stat-time.h>
6254 (Fcopy_file): Copy higher-resolution time stamps.
6255 Prefer to set the time stamp via a file descriptor if that works.
6256 (Fset_file_times, Finsert_file_contents, Fwrite_region)
6257 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
6258 (Fvisited_file_modtime, Fset_visited_file_modtime):
6259 Support higher-resolution time stamps.
6261 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
6263 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
6265 * image.c (prepare_image_for_display, clear_image_cache)
6266 (lookup_image): Port to higer-resolution time stamps.
6268 * keyboard.c (start_polling, bind_polling_period):
6269 Check for time stamp overflow.
6270 (read_char, kbd_buffer_get_event, timer_start_idle)
6271 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
6272 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
6273 Port to higher-resolution time stamps. Do not assume time_t is signed.
6274 (decode_timer): New function. Timers are now vectors of length 9,
6275 not 8, to accommodate the picosecond component.
6276 (timer_check_2): Use it.
6278 * nsterm.m (select_timeout, timeval_subtract): Remove.
6279 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
6280 as they're a bit more accurate and handle overflow better.
6281 (ns_select): Change prototype to be compatible with pselect.
6282 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
6283 * nsterm.h (ns_select): Adjust prototype.
6285 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
6286 us-resolution time stamps.
6287 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
6289 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
6291 * lisp.h (time_overflow): New decl.
6292 (wait_reading_process_output): First arg is now intmax_t, not int,
6293 to accommodate larger waits.
6295 * process.h (struct Lisp_Process.read_output_delay):
6296 Now counts nanoseconds, not microseconds.
6297 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
6299 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
6300 (wait_reading_process_output):
6301 Port to ns-resolution time stamps.
6302 (Faccept_process_output, wait_reading_process_output):
6303 Check for time stamp overflow. Do not assume time_t is signed.
6304 (select_wrapper): Remove; we now use pselect.
6305 (Fprocess_attributes): Now generates ns-resolution time stamps.
6307 * sysdep.c: Include utimens.h. Don't include utime.h
6308 or worry about struct utimbuf; gnulib does that for us now.
6309 (gettimeofday): Remove; gnulib provides a substitute.
6310 (make_timeval): New function.
6311 (set_file_times): Now sets ns-resolution time stamps.
6312 New arg FD; all uses changed.
6313 (time_from_jiffies, ltime_from_jiffies, get_up_time)
6314 (system_process_attributes):
6315 Now returns ns-resolution time stamp. All uses changed.
6316 Check for time stamp overflow.
6318 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
6319 provides a substitute now.
6321 * systime.h: Include timespec.h rather than sys/time.h and time.h,
6322 since it guarantees struct timespec.
6323 (EMACS_TIME): Now struct timespec, so that we can support
6324 ns-resolution time stamps.
6325 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
6326 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
6327 (EMACS_USECS): Remove.
6328 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
6329 so multiply the arg by 1000 before storing it.
6330 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
6332 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

6337 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
6338 (set_file_times, make_time, lisp_time_argument): Adjust signature.
6339 (make_timeval, make_lisp_time, decode_time_components): New decls.
6340 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
6341 that it mishandled time_t overflow. You can't compare by subtracting!
6342 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
6343 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
6345 * term.c: Include <sys/time.h>.
6346 (timeval_to_Time): New function, for proper overflow wraparound.

6354 (w32_get_internal_run_time):
6355 Port to higher-resolution Emacs time stamps.
6356 (ltime): Now accepts single 64-bit integer, as that's more convenient
6359 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
6361 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
6362 for compatibility with pselect. Support ns-resolution time stamps.
6364 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
6366 * xselect.c (wait_for_property_change, x_get_foreign_selection):
6367 Check for time stamp overflow, and support ns-resolution time stamps.
6369 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
6370 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
6371 (timeval_subtract): Remove; no longer needed.
6372 (XTflash, XTring_bell, x_wait_for_event):
6373 Port to ns-resolution time stamps. Don't assume time_t is signed.
6375 2012-06-22 Chong Yidong <cyd@gnu.org>

6379 2012-06-22 Eli Zaretskii <eliz@gnu.org>
6381 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
6382 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
6383 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
6384 staticidx goes up to 1597 out of 1600 = 0x640.)
6386 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
6388 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
6389 Otherwise, the umask might be mistakenly 0 while handling input signals.
6391 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
6393 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

6398 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
6399 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
6400 access to `contents' member of Lisp_Vector objects with AREF and ASET
6403 2012-06-19 Chong Yidong <cyd@gnu.org>
6405 * frame.c (delete_frame): When selecting a frame on a different
6406 text terminal, do not alter the terminal's top-frame.

6409 frame's selected window and its terminal's top-frame.
6410 (unwind_format_mode_line): Restore them.
6411 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
6413 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
6414 since tty frames can be explicitly named.
6415 (prepare_menu_bars): Likewise.
6417 * term.c (Ftty_top_frame): New function.
6419 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
6421 Port byte-code-meter to modern targets.
6422 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
6423 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
6424 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
6425 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
6426 (METER_1, METER_2): Simplify.
6428 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

6432 2012-06-18 Martin Rudalics <rudalics@gmx.at>
6434 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
6435 gets killed during executing of this function (Bug#11665).
6436 Try to always return Qt when the buffer has been actually killed.
6437 (Vkill_buffer_query_functions): In doc-string say that functions
6438 run by this hook should not change the current buffer.
6440 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
6442 Fix recently-introduced process.c problems found by static checking.
6443 * process.c (write_queue_push, write_queue_pop, send_process):

6460 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
6462 * lisp.h (eassert): Assume C89 or later.
6463 This removes the need for CHECK.
6464 (CHECK): Remove. Its comments about always evaluating its
6465 argument were confusing, as 'eassert' typically does not evaluate
6468 * coding.c (produce_chars): Use ptrdiff_t, not int.
6470 * xterm.c (x_draw_underwave): Check for integer overflow.
6471 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
6473 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
6475 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't

6782 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
6783 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
6784 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),
6785 (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.
6786 (roundup_size): New constant.
6787 (struct vector_block): New data type.
6788 (vector_blocks, vector_free_lists, zero_vector): New variables.
6789 (all_vectors): Rename to `large_vectors'.
6790 (allocate_vector_from_block, init_vectors, allocate_vector_from_block)
6791 (sweep_vectors): New functions.
6792 (allocate_vectorlike): Return `zero_vector' as the only vector of
6793 0 items. Allocate new vector from block if vector size is less than
6794 or equal to VBLOCK_BYTES_MAX.
6795 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
6796 (init_alloc_once): Add call to init_vectors.
6798 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
6800 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
6802 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
6804 * doprnt.c (doprnt): Truncate multibyte char correctly.
6805 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
6806 would mishandle a string argument "Xc" if X was a multibyte
6807 character of length 2: it would truncate after X's first byte
6808 rather than including all of X.
6810 2012-06-06 Chong Yidong <cyd@gnu.org>
6812 * buffer.c (word_wrap): Doc fix.
6814 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

6832 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
6835 2012-06-03 Chong Yidong <cyd@gnu.org>
6837 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
6838 (note_mode_line_or_margin_highlight): If there is no help echo,
6839 use mode-line-default-help-echo. Handle the case where the mouse
6840 position is past the end of the mode line string.
6842 * buffer.c (buffer_local_value_1): New function, split from
6843 Fbuffer_local_value; can return Qunbound.
6844 (Fbuffer_local_value): Use it.
6845 (Vmode_line_format): Docstring tweaks.
6847 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
6849 * sysdep.c (system_process_attributes): Improve comment.
6851 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
6853 * keyboard.c: Export real-this-command to Elisp.
6854 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
6855 and DEFVAR it. Update all users.
6857 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
6859 * minibuf.c (Fassoc_string): Remove duplicate declaration.
6861 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
6862 Convert pctcpu and pctmem to Lisp float properly.
6863 Let the compiler fold better, as 100.0/0x8000 is exact.
6865 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
6867 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
6870 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
6872 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
6874 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
6876 For a 'struct window', replace some Lisp_Object fields to
6877 bitfields where appropriate, remove unused fields.
6878 * window.h (struct window): Remove unused 'last_mark_x' and
6879 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
6880 change it's type from Lisp_Object to bitfield.
6881 Change type of 'force_start', 'optional_new_start',
6882 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
6883 fields from Lisp_Object to bitfield. Adjust users accordingly.
6885 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6887 Pacify gcc -Wdouble-precision when using Xaw.
6888 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
6889 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
6890 Use 'float' consistently, rather than 'float' in most places
6891 and 'double' in a couple of places.
6893 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6895 * xdisp.c (handle_stop): Detect whether we have overlay strings
6896 loaded by testing it->current.overlay_string_index to be
6897 non-negative, instead of checking whether n_overlay_strings is
6898 positive. (Bug#11587)
6900 2012-05-31 Chong Yidong <cyd@gnu.org>
6902 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
6904 * doc.c (Fsubstitute_command_keys): Doc fix.
6906 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6908 * search.c (search_buffer): Remove calls to
6909 r_alloc_inhibit_buffer_relocation, as it is now called by
6910 maybe_unify_char, which was the cause of relocation of buffer text
6913 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6915 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
6916 for the duration of call to load_charset, to avoid problems with
6917 callers of maybe_unify_char that access buffer text through C
6920 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
6921 decrement the inhibition flag, instead of just setting or
6924 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6926 Remove obsolete '#define static' cruft.
6927 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
6928 This #undef was "temporary" in 2000; it is no longer needed
6929 now that '#define static' has gone away.
6930 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
6931 (gray_bitmap_bits): Remove; no longer needed.
6932 All uses replaced with definiens.
6933 * xterm.c: Include "bitmaps/gray.xbm".
6935 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6937 Clean up __executable_start, monstartup when --enable-profiling.
6938 The following changes affect the code only when profiling.
6939 * dispnew.c (__executable_start): Rename from safe_bcopy.
6940 Define only on platforms that need it.
6941 * emacs.c: Include <sys/gmon.h> when profiling.
6942 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
6943 (__executable_start): Remove decl, since lisp.h does it now.
6944 (safe_bcopy): Remove decl; no longer has that name.
6945 (main): Coalesce #if into single bit of code, for simplicity.
6946 Cast pointers to uintptr_t, since standard libraries want integers
6948 * lisp.h (__executable_start): New decl.
6950 2012-05-31 Glenn Morris <rgm@gnu.org>
6952 * image.c (Fimagemagick_types): Doc fix.

6969 (Qdefun): Move from eval.c.
6970 * lisp.h (Qdefun): Remove.
6971 * lread.c (read1): Tiny simplification.
6973 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
6975 Do not create empty overlays with the evaporate property (Bug#9642).
6976 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
6977 Bug#9642, but explicitly check that the buffer the overlay would
6978 be moved to is live and rearrange lines to make sure that errors
6979 will not put the overlay in an inconsistent state.
6980 (Fdelete_overlay): Cosmetics.
6982 2012-05-28 Eli Zaretskii <eliz@gnu.org>
6984 * w32term.c (my_bring_window_to_top): New function.
6985 (x_raise_frame): Use handle returned by DeferWindowPos, which
6986 could be different from the original one.
6987 Call my_bring_window_to_top instead of my_set_foreground_window.
6990 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
6991 by calling BringWindowToTop.
6993 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
6994 (WM_EMACS_END): Increase by one.
6996 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
6998 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
6999 This avoids undefined behavior that might cause the eassert
7000 to not catch an out-of-range value.
7002 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
7004 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
7005 Update dependencies.
7007 2012-05-27 Eli Zaretskii <eliz@gnu.org>
7009 * bidi.c (bidi_mirror_char): Fix last change.

7014 when referring to sectname field in printf format.
7016 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
7018 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
7019 Only r_alloc_inhibit_buffer_relocation needed to be added;
7020 the others were already declared.
7022 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
7023 before checking whether it's out of range. Put the check inside
7025 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
7027 2012-05-27 Ken Brown <kbrown@cornell.edu>
7029 * callproc.c (Fcall_process): Restore a line that was accidentally
7030 commented out in the 2011-02-13 change (bug#11547).
7032 2012-05-27 Eli Zaretskii <eliz@gnu.org>
7034 * lisp.h [REL_ALLOC]: Add prototypes for external functions
7035 defined on ralloc.c.
7037 * buffer.c [REL_ALLOC]: Remove prototypes of
7038 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
7039 they are now on lisp.h.
7041 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
7043 * search.c (search_buffer): Use it to inhibit relocation of buffer
7044 text while re_search_2 is doing its job, because re_search_2 is
7045 passed C pointers to buffer text. (Bug#11519)
7047 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
7050 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
7051 state after an additional call to move_it_in_display_line_to, keep
7052 the values of it->max_ascent and it->max_descent found for the
7054 (pos_visible_p): Revert the comparison against bottom_y to what it
7055 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
7058 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
7060 Fix coding-related core dumps with gcc -ftrapv.
7061 The code was computing A - B, where A and B are pointers, and B is
7062 random garbage. This can lead to core dumps on platforms that
7063 have special pointer registers, and it also leads to core dumps on
7064 x86-64 when compiled with gcc -ftrapv. The fix is to compute
7065 A - B only when B is initialized properly.
7066 * coding.c (coding_set_source, coding_set_destination): Return void.
7067 (coding_change_source, coding_change_destinations): New functions,
7068 with the old behaviors of coding_set_source and coding_set_destination.
7069 All callers that need an offset changed to use these new functions.
7071 2012-05-26 Glenn Morris <rgm@gnu.org>
7073 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
7075 2012-05-26 Eli Zaretskii <eliz@gnu.org>
7077 Extend mouse support on W32 text-mode console.
7078 * xdisp.c (draw_row_with_mouse_face):
7079 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
7081 * w32console.c: Include window.h.
7082 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
7084 (initialize_w32_display): Initialize mouse-highlight data.
7086 * w32inevt.c: Include termchar.h and window.h.
7087 (do_mouse_event): Support mouse-autoselect-window. When the mouse
7088 moves, call note_mouse_highlight. If help_echo changed, call
7089 gen_help_event to produce help-echo message in the echo area.
7090 Call clear_mouse_face if mouse_face_hidden is set in the mouse
7093 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
7095 * lread.c (read1): Simplify slightly to avoid an overflow warning
7096 with GCC 4.7.0 on x86-64.
7098 2012-05-26 Eli Zaretskii <eliz@gnu.org>
7100 * bidi.c (bidi_mirror_char): Revert last change: an int is
7101 definitely wide enough here.
7103 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
7105 Fix integer width and related bugs (Bug#9874).
7106 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
7107 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
7108 (string_bytes, check_sblock, allocate_string_data):
7109 (compact_small_strings, Fmake_bool_vector, make_string)
7110 (make_unibyte_string, make_multibyte_string)
7111 (make_string_from_bytes, make_specified_string)
7112 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
7113 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
7115 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7116 (allocate_pseudovector):
7117 Use int, not EMACS_INT, where int is wide enough.
7118 (inhibit_garbage_collection, Fgarbage_collect):
7119 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7120 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
7121 int might not be wide enough.
7122 (bidi_cache_search, bidi_cache_find, bidi_init_it)
7123 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
7124 (bidi_at_paragraph_end, bidi_find_paragraph_start)
7125 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
7126 (bidi_level_of_next_char, bidi_move_to_visually_next):
7127 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7128 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
7129 (Fkill_buffer, Fset_buffer_major_mode)
7130 (advance_to_char_boundary, Fbuffer_swap_text)
7131 (Fset_buffer_multibyte, overlays_at, overlays_in)
7132 (overlay_touches_p, struct sortvec, record_overlay_string)
7133 (overlay_strings, recenter_overlay_lists)
7134 (adjust_overlays_for_insert, adjust_overlays_for_delete)
7135 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
7136 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
7137 (Foverlay_recenter, last_overlay_modification_hooks_used)
7138 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
7139 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7140 (validate_region): Omit unnecessary test for b <= e,
7141 since that's guaranteed by the previous test.
7142 (adjust_overlays_for_delete): Avoid pos + length overflow.
7143 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
7144 (report_overlay_modification):
7145 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7146 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
7147 Omit pointer cast, which isn't needed anyway, and doesn't work
7148 after the EMACS_INT -> ptrdiff_t change.
7149 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
7150 * buffer.h: Adjust decls to match defn changes elsewhere.
7151 (struct buffer_text, struct buffer):
7152 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7153 Use EMACS_INT, not int, where int might not be wide enough.
7154 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
7155 not int, to avoid needless 32-bit limit on 64-bit hosts.
7156 (exec_byte_code): Use tighter memory-full test, one that checks
7157 for alloca overflow. Don't compute the address of the object just
7158 before an array, as that's not portable. Use EMACS_INT, not
7159 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
7160 * callint.c (Fcall_interactively):
7161 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7162 * callproc.c (call_process_kill, Fcall_process):
7163 Don't assume pid_t fits into an Emacs fixnum.
7164 (call_process_cleanup, Fcall_process, child_setup):
7165 Don't assume pid_t fits into int.
7166 (call_process_cleanup, Fcall_process, delete_temp_file)
7167 (Fcall_process_region):
7168 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7169 (Fcall_process): Simplify handling of volatile integers.
7170 Use int, not EMACS_INT, where int will do.
7171 * casefiddle.c (casify_object, casify_region, operate_on_word)
7172 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
7173 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7174 (casify_object): Avoid integer overflow when overallocating buffer.
7175 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
7176 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
7177 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
7178 * category.h (CATEGORYP): Don't assume arg is nonnegative.
7179 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
7180 integers are now checked earlier. All uses replaced with XINT.
7182 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7183 For CCL_MapSingle, check that content and value are in int range.
7184 (ccl_driver, Fregister_code_conversion_map):
7185 Check that Vcode_version_map_vector is a vector.
7186 (resolve_symbol_ccl_program): Check that vector header is in range.
7187 Always copy the vector, so that we can check its contents reliably
7188 now rather than having to recheck each instruction as it's being
7189 executed. Check that vector words fit in 'int'.
7190 (ccl_get_compiled_code, Fregister_ccl_program)
7191 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
7192 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
7193 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
7194 contents are in range.
7195 (Fccl_execute_on_string): Check that status is in range.
7196 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
7197 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
7198 Accept and return EMACS_INT, not int, because callers can pass values
7200 (c_string_width, strwidth, lisp_string_width, chars_in_text)
7201 (multibyte_chars_in_text, parse_str_as_multibyte)
7202 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
7203 (str_as_unibyte, str_to_unibyte, string_count_byte8)
7204 (string_escape_byte8, Fget_byte):
7205 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7206 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
7207 avoid mishandling large integers.
7208 * character.h: Adjust decls to match defn changes elsewhere.
7209 * charset.c (load_charset_map_from_file, find_charsets_in_text)
7210 (Ffind_charset_region):
7211 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7212 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
7213 (load_charset_map_from_vector, Fdefine_charset_internal):
7214 Don't assume fixnum fits in int.
7215 (load_charset_map_from_vector, Fmap_charset_chars):
7216 Remove now-unnecessary CHECK_NATNUMs.
7217 (Fdefine_charset_internal): Check ranges here, more carefully.
7218 Don't rely on undefined behavior with signed left shift overflow.
7219 Don't assume unsigned int fits into fixnum, or that fixnum fits
7220 into unsigned int. Don't require max_code to be a valid fixnum;

7933 Move its few remaining bits of functionality to where they're needed.
7934 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
7935 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
7936 * m/template.h: Remove.
7937 * Makefile.in (M_FILE): Remove. All uses removed.
7938 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
7939 * lisp.h (USE_LSB_TAG):
7940 * mem-limits.h (EXCEEDS_LISP_PTR):
7941 Use VAL_MAX, not VALBITS, in #if.
7942 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
7943 (EMACS_UINT): Define unconditionally now.
7944 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
7945 (BITS_PER_EMACS_INT): New constants, replacing
7946 what used to be in config.h, but not useful in #if.
7947 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
7948 define them any more.
7949 (VAL_MAX): New macro.
7951 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
7952 BITS_PER_EMACS_INT, in #if.
7953 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
7954 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
7955 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
7956 * s/ms-w32.h (DATA_START):
7957 Move here from removed file m/intel386.h.
7958 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
7959 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
7961 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
7963 Assume C89 or later.
7964 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.

7971 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
7972 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
7973 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
7974 * xterm.c (input_signal_count): Assume volatile works.
7976 2012-05-21 Ken Brown <kbrown@cornell.edu>
7978 * xgselect.c (xg_select): Fix first argument in call to 'select'
7981 2012-05-20 Ken Brown <kbrown@cornell.edu>
7983 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
7984 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
7986 2012-05-19 Ken Brown <kbrown@cornell.edu>
7988 * xfns.c (x_in_use): Remove `static' qualifier.
7989 * xterm.h (x_in_use): Declare.
7990 * xgselect.c: Include xterm.h.
7991 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
7992 and `display_arg' (bug#9754).
7994 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
7996 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
7998 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
7999 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
8001 2012-05-18 Eli Zaretskii <eliz@gnu.org>
8003 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
8005 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
8006 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
8008 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
8009 reference to image_cache->refcount.
8010 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
8012 2012-05-17 Juri Linkov <juri@jurta.org>
8014 * search.c (Fword_search_regexp, Fword_search_backward)
8015 (Fword_search_forward, Fword_search_backward_lax)
8016 (Fword_search_forward_lax): Move functions to isearch.el
8017 (bug#10145, bug#11381).
8019 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
8021 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
8023 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
8025 * lread.c (init_obarray): Declare Qt and Qnil as special.
8027 2012-05-14 Glenn Morris <rgm@gnu.org>
8029 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
8030 Put "libexec" before "bin", for the sake of init_callproc_1.
8032 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
8034 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
8036 * unexaix.c: Port to more-recent AIX compilers.
8037 (report_error, report_error_1, make_hdr, copy_sym)
8038 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
8039 Make arguments const char *, not char *, to avoid violations of C
8040 standard and to fix some AIX warnings reported by Gilles Pion.
8042 2012-05-14 Eli Zaretskii <eliz@gnu.org>
8044 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
8045 already have overlays loaded.
8046 (handle_single_display_spec): Before returning without displaying
8047 fringe bitmap, synchronize the bidi iterator with the main display
8048 iterator, by calling iterate_out_of_display_property.
8049 (iterate_out_of_display_property): Detect buffer iteration by
8050 testing that it->string is a Lisp string.
8051 (get_next_display_element): When the current object is exhausted,
8052 and there's something on it->stack, call set_iterator_to_next to
8053 proceed with what's on the stack, instead of returning zero.
8054 (set_iterator_to_next): If called at the end of a Lisp string,
8055 proceed to consider_string_end without incrementing string
8056 position. Don't increment display vector index past the end of
8057 the display vector. (Bug#11417)
8058 (pos_visible_p): Don't report a position visible when move_it_to
8059 stopped at the last line of window, which happens to be scanned
8060 backwards by the bidi iteration. (Bug#11464)
8062 2012-05-14 Eli Zaretskii <eliz@gnu.org>
8064 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
8065 and right-margin display specs even if the spec is invalid or we
8066 are on a TTY, and thus unable to display on the fringes.
8067 That's because the text with the property will not be displayed anyway,
8068 so we need to signal to the caller that this is a "replacing"
8069 display spec. This fixes display when the spec is invalid or we
8072 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
8074 * unexaix.c (make_hdr): Fix typo in prototype.
8075 This bug broke the build on AIX. Problem reported by Gilles Pion.
8077 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
8079 * keyboard.c (kbd_buffer_get_event): Read special events also in
8080 batch mode. (Bug#11415)
8082 2012-05-12 Glenn Morris <rgm@gnu.org>
8084 * ns.mk: Update for ns_appbindir no longer having trailing "/".
8086 2012-05-12 Eli Zaretskii <eliz@gnu.org>
8088 * lisp.mk (lisp): Add newcomment.elc.
8090 2012-05-12 Glenn Morris <rgm@gnu.org>
8092 * Makefile.in (MKDIR_P): New, set by configure.
8093 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
8095 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
8097 Remove unused function hourglass_started.
8098 * dispextern.h (hourglass_started):
8099 * w32fns.c (hourglass_started):
8100 * xdisp.c (hourglass_started): Remove.
8102 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
8104 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
8105 Update dependencies.
8107 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
8109 * xgselect.c (xg_select): Put maxfds+1 into a var.
8110 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
8112 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
8114 2012-05-10 Dave Abrahams <dave@boostpro.com>
8116 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
8117 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
8119 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
8121 * dbusbind.c (xd_registered_buses): New internal Lisp object.
8122 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
8123 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
8124 Initialize xd_registered_buses.
8126 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
8128 Untag more efficiently if USE_LSB_TAG.
8129 This is based on a proposal by YAMAMOTO Mitsuharu in
8130 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
8131 For an admittedly artificial (nth 8000 longlist) benchmark on
8132 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
8133 Emacs's overall text size by 1%.
8134 * lisp.h (XUNTAG): New macro.
8135 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
8136 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
8137 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
8138 * eval.c (Fautoload):
8139 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
8140 * frame.h (XFRAME): Use XUNTAG.
8142 Port recent dbusbind.c changes to 32-bit --with-wide-int.
8143 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
8144 Remove unportable assumptions about print widths of types like
8146 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
8147 intptr_t when converting between pointer and integer, to avoid GCC
8148 warnings about wrong width.
8150 2012-05-09 Eli Zaretskii <eliz@gnu.org>
8152 * w32proc.c (new_child): Force Windows to reserve only 64KB of
8153 stack for each reader_thread, instead of defaulting to 8MB
8154 determined by the linker. This avoids failures in creating
8155 subprocesses on Windows 7, see the discussion in this thread:
8156 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
8158 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
8160 Fix up display of the *Minibuf-0* buffer in the mini window.
8161 * keyboard.c (read_char): Don't clear the echo area if there's no
8163 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
8164 contents of *Minibuf-0*) if there's no message displayed in its stead.
8166 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
8168 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
8171 2012-05-06 Chong Yidong <cyd@gnu.org>
8173 * lisp.mk (lisp): Update.
8175 2012-05-05 Jim Meyering <meyering@redhat.com>
8177 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
8179 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
8181 * data.c (PUT_ERROR): New macro.
8182 (syms_of_data): Use it. Add new error type `user-error'.
8183 * undo.c (user_error): New function.
8184 (Fprimitive_undo): Use it.
8185 * print.c (print_error_message): Adjust print style for `user-error'.
8186 * keyboard.c (user_error): New function.
8187 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
8189 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
8191 Do not limit current-time-string to years 1000..9999.
8192 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
8193 (Fcurrent_time_string): Support any year that is supported by the
8194 underlying localtime representation. Don't use asctime, as it
8195 has undefined behavior for years outside the range -999..9999.
8197 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
8199 Fix race conditions involving setenv, gmtime, localtime, asctime.
8200 Without this fix, interrupts could mess up code that uses these
8201 nonreentrant functions, since setting TZ invalidates existing
8202 tm_zone or tzname values, and since most of these functions return
8203 pointers to static storage.
8204 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
8205 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
8206 Grow the critical sections to include not just invoking
8207 localtime/gmtime, but also accessing these functions' results
8208 including their tm_zone values if any, and any related TZ setting.
8209 (format_time_string): Last arg is now struct tm *, not struct tm **,
8210 so that the struct tm is saved in the critical section.
8211 All callers changed. Simplify allocation of initial buffer, partly
8212 motivated by the fact that memory allocation needs to be outside
8213 the critical section.
8215 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
8217 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
8218 with RESET_INTERVAL.
8220 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
8221 Remove duplicated buffer name initialization.
8223 2012-05-02 Jim Meyering <jim@meyering.net>
8225 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
8227 * xfns.c (x_window): Use xstrdup (Bug#11375).
8229 2012-05-02 Eli Zaretskii <eliz@gnu.org>
8231 * xdisp.c (pos_visible_p): If already at a newline from the
8232 display string before the 'while' loop, don't walk back the glyphs
8233 from it3.glyph_row. Solves assertion violation when the display
8234 string begins with a newline (egg.el). (Bug#11367)
8236 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
8238 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
8241 2012-05-01 Glenn Morris <rgm@gnu.org>
8243 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
8244 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
8245 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
8246 All were removed before 23.1.
8248 * dispnew.c: Remove HAVE_LIBNCURSES test;
8249 it is always true on relevant platforms.
8251 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
8252 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
8254 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
8256 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
8258 * .gdbinit (xpr): Remove checks for no longer existing misc types.
8259 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
8262 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
8264 Do not avoid creating empty evaporating overlays (Bug#9642).
8265 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
8266 That is, do not delete an evaporating overlay if it becomes
8267 empty after its bounds are adjusted to fit within its buffer.
8268 This fix caused other problems, and I'm reverting it until we get
8269 to the bottom of them.
8271 2012-04-27 Chong Yidong <cyd@gnu.org>
8273 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
8275 2012-04-27 Eli Zaretskii <eliz@gnu.org>
8277 * xdisp.c (pos_visible_p): If the window start position is beyond
8278 ZV, start the display from buffer beginning. Prevents assertion
8279 violation in init_iterator when the minibuffer window is scrolled
8282 * window.c (window_scroll_pixel_based): Likewise.
8284 2012-04-27 Chong Yidong <cyd@gnu.org>
8286 * keymap.c (where_is_internal): Doc fix (Bug#10872).
8288 2012-04-27 Glenn Morris <rgm@gnu.org>
8290 * fileio.c (Fcopy_file, Fset_file_selinux_context):
8291 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
8293 2012-04-27 Eli Zaretskii <eliz@gnu.org>
8295 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
8296 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
8298 2012-04-26 Eli Zaretskii <eliz@gnu.org>
8300 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
8301 display element, check also the underlying string or buffer
8302 character. (Bug#11341)
8304 * w32menu.c: Include w32heap.h.
8305 (add_menu_item): If the call to AppendMenuW (via
8306 unicode_append_menu) fails, disable Unicode menus only if we are
8307 running on Windows 9X/Me.
8309 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
8311 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
8312 (xgetint): Add missing shift for LSB tags.
8314 2012-04-24 Martin Rudalics <rudalics@gmx.at>
8316 * keyboard.c (read_char): Don't wipe echo area for select window
8317 events: These might get delayed via `mouse-autoselect-window'
8320 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
8322 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
8323 manipulation of :loaded-from data.
8325 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
8327 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
8328 now a cons (bug#11311).
8330 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
8332 Do not create empty overlays with the evaporate property (Bug#9642).
8333 * buffer.c (Fmove_overlay): Delete an evaporating overlay
8334 if it becomes empty after its bounds are adjusted to fit within
8335 its buffer. Without this fix, in a nonempty buffer (let ((o
8336 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
8337 yields an empty overlay that has the evaporate property, which is
8338 not supposed to happen.
8340 Fix minor GTK3 problems found by static checking.
8341 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
8342 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
8343 (struct _EmacsFixedClass, emacs_fixed_get_type):
8344 Move decls here from emacsgtkfixed.h, since they needn't be public.
8345 (emacs_fixed_get_type): Now static.
8346 (emacs_fixed_class_init): Omit unused local.
8347 (emacs_fixed_child_type): Remove; unused.
8348 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
8349 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
8350 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
8351 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
8352 (EMACS_FIXED_GET_CLASS): Remove; unused.
8353 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
8355 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
8356 Problem reported by Juanma Barranquero for Windows -Wunused-function.
8358 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
8360 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
8361 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
8362 (__malloc_size_t, __malloc_ptrdiff_t):
8363 Remove. All uses removed, replaced by the definiens if needed,
8364 since we can assume C89 or better now.
8365 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
8366 (protect_malloc_state, align, get_contiguous_space)
8367 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

8373 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
8374 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
8375 Define using prototypes, not old style.
8376 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
8377 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
8378 (align): Don't assume that signed integer overflow wraps around.
8379 Omit unused local var.

8442 since the two debugging options are incompatible.
8443 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
8445 (mem_init, mem_insert, mem_insert_fixup):
8446 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

8541 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
8542 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

8612 2012-04-11 Daniel Colascione <dancol@dancol.org>
8614 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
8615 against is gone. It's better to use vfork now so that when Cygwin
8616 gains a new, working vfork, we use it automatically (bug#10398).
8618 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

8673 2012-04-09 Eli Zaretskii <eliz@gnu.org>
8675 * xdisp.c (set_cursor_from_row): If the display string appears in
8676 the buffer at position that is closer to point than the position
8677 after the display string, display the cursor on the first glyph of
8678 the display string. Fixes cursor display when a 'display' text
8679 property immediately follows invisible text. (Bug#11094)
8681 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
8683 composite.c: use 'double' consistently
8684 * composite.c (get_composition_id): Use 'double' consistently
8685 instead of converting 'float' to 'double' and vice versa; this is
8686 easier to understand and avoids a GCC warning.

8735 [!WINDOWSNT]: New macros.
8736 (init_libxml2_functions, libxml2_loaded_p): New functions.
8737 (parse_region): Call fn_xmlCheckVersion instead of using the macro
8738 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.

8760 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
8761 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
8762 about subtle differences between FETCH_CHAR* and STRING_CHAR*
8763 macros related to unification of CJK characters. For the details,
8764 see the discussion following the message here:
8765 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
8767 2012-04-04 Chong Yidong <cyd@gnu.org>

8784 position we get to after a call to move_it_to fails the
8785 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
8786 only if we wind up in a string from display property. (Bug#11063)
8788 * window.c (Fdelete_other_windows_internal): Invalidate the row
8789 and column information about mouse highlight, so that redisplay
8790 restores it after reallocating the glyph matrices. (Bug#7464)
8792 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
8793 string comes from a `display' text property, use the buffer
8794 position of that property as if we actually saw that position in
8796 (move_it_by_lines): Remove the assertion that
8797 "it->current_x == 0 && it->hpos == 0" which can be legitimately
8798 violated when there's a before-string at the beginning of a line.
8801 2012-03-30 Eli Zaretskii <eliz@gnu.org>

8854 !SYNC_INPUT. (Bug#11080)
8856 2012-03-23 Eli Zaretskii <eliz@gnu.org>
8858 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
8859 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
8860 when fetching a multibyte character consumes more bytes than
8861 CHAR_BYTES returns, due to unification of CJK characters in
8862 string_char. (Bug#11073)
8864 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
8866 * process.c (wait_reading_process_output): Handle pty disconnect
8867 by refraining from sending oneself a SIGCHLD (bug#10933).

8884 * w32proc.c (Fw32_set_console_codepage)
8885 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
8888 2012-03-20 Chong Yidong <cyd@gnu.org>
8890 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
8891 to reflect default non-nil value of redisplay-dont-pause.
8893 2012-03-19 Kenichi Handa <handa@m17n.org>
8895 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
8896 it fit in a valid range (Bug#11003).
8898 2012-03-18 Eli Zaretskii <eliz@gnu.org>
8900 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
8901 that is not from display property, accept the row as a "cursor
8902 row" if one of the string's character has a non-nil `cursor'
8903 property. Fixes cursor positioning when there are newlines in
8904 overlay strings, e.g. in icomplete.el. (Bug#11035)
8906 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
8908 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
8910 2012-03-12 Chong Yidong <cyd@gnu.org>
8912 * eval.c (inhibit_lisp_code): Rename from
8913 inhibit_window_configuration_change_hook; move from window.c.
8915 * xfns.c (unwind_create_frame_1, Fx_create_frame):
8916 * window.c (run_window_configuration_change_hook)
8917 (syms_of_window): Callers changed.

8937 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
8940 2012-03-03 Glenn Morris <rgm@gnu.org>
8942 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
8944 2012-03-02 Eli Zaretskii <eliz@gnu.org>
8946 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
8947 position past the first glyph_row that ends at ZV. (Bug#10902)
8948 (redisplay_window, next_element_from_string): Fix typos in
8950 (redisplay_window): Pass to move_it_vertically the margin in
8951 pixels, not in screen lines.
8953 2012-03-02 Glenn Morris <rgm@gnu.org>
8955 * buffer.c (buffer-list-update-hook): Doc fix.
8957 2012-02-29 Eli Zaretskii <eliz@gnu.org>

8960 push_it before setting up the iterator for the first overlay
8961 string, even if we have an empty string loaded.
8962 (next_overlay_string): If there's an empty string on the iterator
8963 stack, pop the stack. (Bug#10903)
8965 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
8967 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
8968 Suggested by Stefan Monnier in
8969 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
8970 * alloc.c (widen_to_Lisp_Object): New static function.
8971 (mark_memory): Also mark Lisp_Objects by fetching pointer words
8972 and widening them to Lisp_Objects. This would work even if
8973 USE_LSB_TAG is defined and wide integers are used, which might
8974 happen in a future version of Emacs.
8976 2012-02-25 Chong Yidong <cyd@gnu.org>
8978 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
8981 * xselect.c (Fx_selection_exists_p): Doc fix.
8982 (x_clipboard_manager_save_all): Print an informative message
8983 before saving to clipboard manager.
8985 2012-02-24 Chong Yidong <cyd@gnu.org>
8987 * keyboard.c (process_special_events): Handle all X selection
8988 requests in kbd_buffer, not just the next one (Bug#8869).
8990 2012-02-23 Chong Yidong <cyd@gnu.org>
8992 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
8993 call when setting menu-bar-lines and tool-bar-lines parameters.
8994 (unwind_create_frame_1): New helper function.
8996 * window.c (inhibit_window_configuration_change_hook): New var.
8997 (run_window_configuration_change_hook): Obey it.
8998 (syms_of_window): Initialize it.
9000 2012-02-22 Chong Yidong <cyd@gnu.org>
9002 * xterm.c (x_draw_image_relief): Add missing type check for

9007 * fileio.c (Vfile_name_handler_alist): Doc fix.
9009 * buffer.c (Fget_file_buffer): Protect against invalid file
9010 handler return value.
9012 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
9014 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
9015 when computing $valmask.
9017 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
9018 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
9019 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
9020 It's useless in that case, and it can cause problems on hosts
9021 that allocate halves of EMACS_INT values separately.
9022 Reported by Dan Horák. Diagnosed by Andreas Schwab in
9023 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
9024 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
9025 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
9026 it avoids undefined behavior on hosts where shifting right by more
9027 than the word width has undefined behavior.
9029 2012-02-19 Chong Yidong <cyd@gnu.org>
9031 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
9032 (Funhandled_file_name_directory, Ffile_name_as_directory)
9033 (Fdirectory_file_name, Fexpand_file_name)

9051 2012-02-15 Chong Yidong <cyd@gnu.org>
9053 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
9054 marked as special. Also, starting docstrings with * is obsolete.
9056 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
9058 * gnutls.c (emacs_gnutls_write): Fix last change.
9060 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

9069 2012-02-12 Chong Yidong <cyd@gnu.org>
9071 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
9072 as that creates a dangerous corner case.
9074 * window.c (Fdelete_window_internal): Invalidate the mouse
9075 highlight (Bug#9904).
9077 2012-02-12 Glenn Morris <rgm@gnu.org>

9082 * nsselect.m (Fx_own_selection_internal)
9083 (Fx_disown_selection_internal, Fx_selection_exists_p)
9084 (Fx_selection_owner_p, Fx_get_selection_internal):
9085 Sync docs and argument specs with the xselect.c versions.
9087 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
9089 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

9107 2012-02-07 Chong Yidong <cyd@gnu.org>
9109 * buffer.c (Fbuffer_local_variables)
9110 (buffer_lisp_local_variables): Handle unbound vars correctly;
9111 don't let Qunbound leak into Lisp.
9113 2012-02-07 Glenn Morris <rgm@gnu.org>
9115 * image.c (Fimagemagick_types): Doc fix.
9117 * image.c (imagemagick-render-type): Change it from a lisp object
9118 to an integer. Move the doc here from the lisp manual.

9123 * doc.c (store_function_docstring): Avoid applying docstring of
9124 alias to base function (Bug#2603).
9126 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
9128 * .gdbinit (pp1, pv1): Remove redundant defines.
9131 2012-02-04 Chong Yidong <cyd@gnu.org>

9150 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
9152 Handle overflow when computing char display width (Bug#9496).
9153 * character.c (char_width): Return EMACS_INT, not int.
9154 (char_width, c_string_width): Check for overflow when
9155 computing the width; this is possible now that individual
9156 characters can have unbounded width. Problem introduced
9157 by merge from Emacs 23 on 2012-01-19.
9159 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

9174 2012-02-02 Kenichi Handa <handa@m17n.org>
9176 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
9177 0, do not call append_composite_glyph.

9188 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
9189 first 2 arguments are identical. This makes inserting large
9190 output from a subprocess an order of magnitude faster on
9191 MS-Windows, where all sbrk'ed memory is always contiguous.

9249 * character.c (char_width): New function.
9250 (Fchar_width, c_string_width, lisp_string_width):

9276 2012-01-11 Glenn Morris <rgm@gnu.org>
9278 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
9279 from load-path also when installation-directory is nil. (Bug#10208)
9281 2012-01-10 Glenn Morris <rgm@gnu.org>
9283 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.

9290 * xdisp.c (rows_from_pos_range): Accept additional argument
9291 DISP_STRING, and accept any glyph in a row whose object is that
9292 string as eligible for mouse highlight. Fixes mouse highlight of
9293 display strings from overlays. (Bug#10464)
9295 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
9297 emacs: fix an auto-save permissions race condition (Bug#10400)
9298 * fileio.c (auto_saving_dir_umask): New static var.
9299 (Fmake_directory_internal): Use it.
9300 (do_auto_save_make_dir): Set it, instead of invoking chmod after
9301 creating the directory. The old code temporarily assigns
9302 too-generous permissions to the directory.
9303 (do_auto_save_eh): Clear it.
9304 (Fdo_auto_save): Catch all errors, not just file errors, so
9305 that the var is always cleared.
9307 2012-01-07 Eli Zaretskii <eliz@gnu.org>
9309 * search.c (scan_buffer): Pass character positions to
9310 know_region_cache, not byte positions. (Bug#6540)

9810 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
9811 is set, removing the need for VIRT_ADDRESS_VARIES.
9812 (PURE_P): Use a more-efficient implementation that needs just one
9813 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
9814 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
9815 to 4 (xorl, subq, cmpq, setbe).

9827 (erase_phys_cursor, update_window_cursor, show_mouse_face)
9828 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
9829 behave as if the cursor position were at the window margin.
9831 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
9832 and the cursor position is out of bounds, behave as if the cursor

10299 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
10300 instead of calling the "wide" APIs directly.
10302 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
10304 * w32.h (syms_of_w32font): Add prototype.
10306 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
10308 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
10309 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
10310 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
10311 (Fmove_to_window_line): Doc fix.
10313 2011-10-27 Chong Yidong <cyd@gnu.org>
10315 * process.c (make_process): Set gnutls_state to NULL.
10317 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
10318 non-NULL, regardless of GNUTLS_INITSTAGE.
10319 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
10320 an error. Set process slots as soon as we allocate them.
10322 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
10324 2011-10-27 Chong Yidong <cyd@gnu.org>
10326 * gnutls.c (emacs_gnutls_deinit): New function.
10327 Deallocate credentials structures as well as calling gnutls_deinit.
10328 (Fgnutls_deinit, Fgnutls_boot): Use it.
10330 * process.c (make_process): Initialize GnuTLS credentials to NULL.
10331 (deactivate_process): Call emacs_gnutls_deinit.
10333 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
10335 * image.c (x_create_x_image_and_pixmap):
10336 * w32.c (sys_rename, w32_delayed_load):
10337 * w32font.c (fill_in_logfont):
10338 * w32reg.c (x_get_string_resource): Silence compiler warnings.
10340 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
10342 * w32fns.c (w32_default_color_map): New function,
10343 extracted from Fw32_default_color_map.
10344 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
10346 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
10348 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
10350 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
10352 * keyboard.c (test_undefined): New function (bug#9751).
10353 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
10355 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
10357 * sysdep.c (init_sys_modes): Fix the check for the controlling
10358 terminal (Bug#6649).
10360 2011-10-20 Eli Zaretskii <eliz@gnu.org>
10362 * dispextern.h (struct bidi_it): New member next_en_type.
10364 * bidi.c (bidi_line_init): Initialize the next_en_type member.
10365 (bidi_resolve_explicit_1): When next_en_pos is valid for the
10366 current character, check also for next_en_type being WEAK_EN.
10367 (bidi_resolve_weak): Don't enter the expensive loop if the current
10368 position is before next_en_pos. Record the bidi type of the first
10369 non-ET, non-BN character we find, in addition to its position.
10370 (bidi_level_of_next_char): Invalidate next_en_type when
10371 next_en_pos is over-stepped.
10373 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
10375 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
10376 * editfns.c: Rewrite current-time-zone so that it invokes
10377 the equivalent of (format-time-string "%Z") to get the time zone name.
10378 This fixes a bug when the time zone name contains characters that
10379 need converting from the system time locale to Emacs internal format.
10380 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
10381 that patch fixed format-time-string to do the conversion, but
10382 I forgot to fix current-time-zone.
10383 (format_time_string): New function, containing most of
10384 what Fformat_time_string used to contain.
10385 (Fformat_time_string): Rewrite in terms of format_time_string.
10386 This doesn't change this function's behavior.
10387 (current-time-zone): Rewrite to use format_time_string.
10388 This fixes the bug reported by Michael Schierl in
10389 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
10390 Jason Rumney's 2007-06-07 change worked around this bug, but
10392 * systime.h (tzname, timezone): Remove no-longer-used declarations.
10394 2011-10-19 Eli Zaretskii <eliz@gnu.org>
10396 * xdisp.c (start_display): If the character at POS is displayed
10397 via a display vector, reset IT->current.dpvec_index to zero.
10398 (try_window_reusing_current_matrix): If a line ends in a display
10399 vector or the next line starts in a display vector, continue
10400 redrawing the window even though the character position of
10401 start_row was reached.
10404 2011-10-18 Chong Yidong <cyd@gnu.org>
10406 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
10407 with nobreak-char-display too.
10409 2011-10-18 Eli Zaretskii <eliz@gnu.org>
10411 Fix part 3 of bug#9771.
10412 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
10413 (bidi_resolve_neutral): Don't enter the expensive loop looking for
10414 non-neutral characters if the current character is a paragraph
10415 separator (a.k.a. Newline). This avoids running the same
10416 expensive loop twice, once when we consume the preceding newline
10417 and the other time when the line actually needs to be displayed.
10418 Avoid the loop when we see neutrals on the base embedding level
10419 following a character whose directionality is the same as the
10420 paragraph's. This avoids running the expensive loop when a line
10421 ends in a long sequence of neutrals, like control characters.
10422 Add assertion against STRONG_AL type. Slightly rearrange code
10423 that determines the type of a neutral given the first non-neutral
10425 (bidi_level_of_next_char): Set next_en_pos to zero when
10426 invalidating its info.
10428 2011-10-17 Eli Zaretskii <eliz@gnu.org>
10430 * xdisp.c (push_display_prop): Determine whether to record string
10431 or buffer position by IT->string, not by IT->method. Allow
10432 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
10433 (move_it_vertically_backward): Don't look for character position
10434 immediately after the newline when in a continuation line.
10437 2011-10-15 Martin Rudalics <rudalics@gmx.at>
10439 * window.c (coordinates_in_window): Rewrite and delabelize
10440 vertical border check. (Bug#5357) (Bug#9618)
10442 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
10444 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
10445 errors in XSetWindowBorder (bug#9310).
10447 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
10449 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
10450 avoid crash when xmalloc overrun checking is enabled.
10452 2011-10-13 Eli Zaretskii <eliz@gnu.org>
10454 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
10455 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
10456 cursor motion with <left> and <right> arrow keys.
10458 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
10459 some callers set that themselves.
10461 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10463 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
10464 display string and the previous row comes from the same string and
10465 is empty. (Bug#9739) (Bug#9738)
10467 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
10469 * doc.c (get_doc_string): Encode file name (bug#9735).
10471 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10473 * bidi.c (bidi_level_of_next_char):
10474 * xdisp.c (get_visually_first_element): Remove old incorrect
10475 comments regarding the Unicode Line Separator character.
10477 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
10479 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
10481 * alloc.c (Fgc_status): Do not access beyond zombies array
10482 boundary if nzombies > MAX_ZOMBIES.
10483 * alloc.c (dump_zombies): Add missing format specifier.
10485 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
10487 * xdisp.c (set_cursor_from_row): Simplify conditionals,
10488 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
10490 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
10491 Some packages use them to denote characters with modifiers.
10493 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
10495 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
10496 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
10497 matching a pp-number. Rename parameter var to var1.
10499 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
10501 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
10503 2011-10-08 Glenn Morris <rgm@gnu.org>
10505 * callint.c (Fcall_interactively): Give a more explicit error for the
10506 'c' case with a non-character input. (Bug#8479)
10508 2011-10-08 Eli Zaretskii <eliz@gnu.org>
10510 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
10512 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
10513 lines that are hscrolled on the left.
10515 * dispnew.c (buffer_posn_from_coords): Account for a possible
10516 presence of header-line. (Bug#4426)
10518 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
10520 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
10521 Don't advertise functionality which we discourage or doesn't work.
10523 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
10525 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
10526 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
10527 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
10528 this makes Emacs dump core during garbage collection on rare
10529 occasions. sizeof is obviously inferior to offsetof here, so
10530 stick with offsetof.
10531 (GC_POINTER_ALIGNMENT): New macro.
10532 (mark_memory): Omit 3rd (offset) arg; caller changed.
10533 Don't assume EMACS_INT alignment is the same as pointer alignment.
10535 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
10537 * keyboard.c (read_key_sequence_remapped): New var.
10538 (read_key_sequence): Compute remapping in the right buffer.
10539 (command_loop_1): Use read_key_sequence's remapping directly.
10541 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
10543 * dired.c (file_name_completion): Don't expand file name.
10544 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
10545 before checking file name handler.
10547 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
10548 they've been requested explicitly (bug#9591).
10550 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
10552 * keymap.c (Fsingle_key_description): Use make_specified_string
10553 instead of build_string to build string from push_key_description.
10556 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10558 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
10559 This fixes a Y2038 bug on 64-bit hosts.
10560 * buffer.c (reset_buffer):
10561 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
10562 (Fclear_buffer_auto_save_failure):
10563 Use 0, not -1, to represent an unset failure time, since time_t
10564 might not be signed.
10566 Remove dependency on glibc malloc internals.
10567 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10568 Move back here from lisp.h, but with their new implementations.
10569 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10570 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
10571 * charset.c (charset_table_init): New static var.
10572 (syms_of_charset): Use it instead of xmalloc. This removes a
10573 dependency on glibc malloc internals. See Eli Zaretskii's comment in
10574 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
10575 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10576 Move back to alloc.c.
10577 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10578 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
10580 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
10582 * nsterm.m (windowDidResize): Call x_set_window_size only when
10583 ns_in_resize is true. Otherwise set pixelwidth/height and
10584 call change_frame_size (Bug#9628).
10586 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10588 Port --enable-checking=all to Fedora 14 x86-64.
10589 * charset.c (syms_of_charset): Also account for glibc malloc's
10590 internal overhead when calculating the initial malloc maximum.
10592 Port --enable-checking=all to Fedora 14 x86.
10593 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10595 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
10596 (overrun_check_realloc, overrun_check_free):
10597 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
10598 That way, xmalloc returns a properly-aligned pointer even if
10599 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
10600 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
10601 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
10602 into account when calculating the initial malloc maximum.
10603 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10604 Move here from alloc.c, so that charset.c can use it too.
10605 Properly align; the old code wasn't right for common 32-bit hosts
10606 when configured with --enable-checking=all.
10607 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10608 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
10610 2011-09-29 Eli Zaretskii <eliz@gnu.org>
10612 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
10615 2011-09-28 Eli Zaretskii <eliz@gnu.org>
10617 * xdisp.c (compute_display_string_end): If there's no display
10618 string at CHARPOS, return -1.
10620 * bidi.c (bidi_fetch_char): When compute_display_string_end
10621 returns a negative value, treat the character as a normal
10622 character not covered by a display string. (Bug#9624)
10624 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
10626 * lread.c (Fread_from_string): Fix typo in docstring.
10628 2011-09-27 Eli Zaretskii <eliz@gnu.org>
10630 * xdisp.c (handle_invisible_prop): If invisible text ends on a
10631 newline, reseat the iterator instead of bidi-iterating there one
10632 character at a time. (Bug#9610)
10633 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
10634 TO_CHARPOS if the bidi iterator is at base embedding level.
10636 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
10638 * lread.c (readevalloop): Use correct code for NBSP.
10639 (read1): Likewise. (Bug#9608)
10641 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
10643 * dbusbind.c (Fdbus_register_signal): When service is not
10644 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
10646 2011-09-25 Glenn Morris <rgm@gnu.org>
10648 * buffer.c (truncate-lines): Doc fix.
10650 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
10652 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
10653 (Fset_window_next_buffers): Doc fix.
10655 2011-09-24 Glenn Morris <rgm@gnu.org>
10657 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
10659 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
10661 Fix minor problems found by static checking.
10662 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
10663 * indent.c (Fvertical_motion): Fix == vs = typo.
10665 2011-09-24 Eli Zaretskii <eliz@gnu.org>
10667 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
10668 Default value is now t. Doc fix.
10670 * indent.c (Fvertical_motion): Compute and apply the overshoot
10671 logic when moving up, not only when moving down. Fix the
10672 confusing name and values of the it_overshoot_expected variable;
10673 logic changes accordingly. (Bug#9254) (Bug#9549)
10675 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
10676 CHARPOS is covered by a display string which includes newlines.
10677 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
10678 is covered by a display string with embedded newlines.
10680 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
10682 * dbusbind.c (Fdbus_register_signal): Add match rule to
10683 Vdbus_registered_objects_table. (Bug#9581)
10684 (Fdbus_register_method, Vdbus_registered_objects_table):
10687 2011-09-24 Jim Meyering <meyering@redhat.com>
10689 do not ignore write error for any output size
10690 The previous change was incomplete.
10691 While it makes emacs --batch detect the vast majority of stdout
10692 write failures, errors were still ignored whenever the output size is
10693 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
10694 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
10695 && echo FAIL: ignored write error
10696 FAIL: ignored write error
10697 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
10698 && echo FAIL: ignored write error
10699 FAIL: ignored write error
10700 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
10702 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
10704 * emacs.c (Fkill_emacs): In noninteractive mode exit
10705 non-successfully if a write error occurred on stdout. (Bug#9574)
10707 2011-09-21 Eli Zaretskii <eliz@gnu.org>
10709 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
10712 * dispextern.h (struct it): Update the comment documenting what
10715 2011-09-20 Eli Zaretskii <eliz@gnu.org>
10717 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
10718 a display string, extend search for cursor position to end of row.
10719 (find_row_edges): If the row ends in a newline from a display
10720 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
10721 Handle the case of a display string with multiple newlines.
10722 (Fcurrent_bidi_paragraph_direction): Fix search for previous
10723 non-empty line. Fixes confusing cursor motion with arrow keys at
10724 the beginning of a line that starts with whitespace.
10726 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
10728 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
10731 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
10733 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
10734 boolean (Bug#9154).
10736 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10738 * xdisp.c (display_line): Record maximum and minimum buffer
10739 positions even if no glyphs were produced (e.g., by a zero-width
10740 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
10741 buffer positions that will be removed from the glyph row because
10743 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
10744 column is beyond frame width: don't subtract 1 "pixel" when
10745 computing width of the stretch.
10746 (reseat_at_next_visible_line_start): Undo the change made on
10747 2011-09-17 that saved paragraph information and restored it after
10748 the call to `reseat'. (Bug#9545)
10750 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10752 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
10753 and turn window cursor on if cleared (Bug#9415).
10755 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
10757 * search.c (boyer_moore): Take unibyte characters from pattern
10758 literally. (Bug#9458)
10760 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10762 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
10764 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
10766 Fix minor problem found by static checking.
10767 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
10768 initialized, to pacify gcc -Wuninitialized.
10770 * fileio.c: Report proper errno when syscall falls.
10771 (Finsert_file_contents): Save and restore errno,
10772 so that report_file_error outputs the correct diagnostic.
10773 (Fwrite_region) [CLASH_DETECTION]: Likewise.
10775 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10777 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
10779 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10781 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
10782 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
10784 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10786 * xdisp.c (reseat_at_next_visible_line_start): Keep information
10787 about the current paragraph and restore it after the call to reseat.
10789 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
10790 (bidi_find_paragraph_start): Search back for paragraph beginning
10791 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
10792 (bidi_move_to_visually_next): Only trigger paragraph-related
10793 computations when the last character is a newline or at EOB, not
10794 just any NEUTRAL_B. (Bug#9470)
10796 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
10797 truncated lines if point is covered by a display string. (Bug#9524)
10799 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
10801 * xselect.c: Relax test for outgoing X longs (Bug#9498).
10802 (cons_to_x_long): New function.
10803 (lisp_data_to_selection_data): Use it. Correct the test for
10804 short-versus-long data; it was negated. Break out of vector
10805 loop, for efficiency, when a long datum is discovered.
10807 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
10809 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
10811 2011-09-16 Eli Zaretskii <eliz@gnu.org>
10813 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
10814 GCC PR/17406) by declaring this function with external scope.
10816 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10818 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
10819 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
10821 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
10823 * editfns.c (Fformat): Correctly handle text properties on "%%".
10825 2011-09-15 Eli Zaretskii <eliz@gnu.org>
10827 * xterm.c (x_draw_composite_glyph_string_foreground):
10828 * w32term.c (x_draw_composite_glyph_string_foreground):
10829 * term.c (encode_terminal_code):
10830 * composite.c (composition_update_it, get_composition_id):
10831 * xdisp.c (get_next_display_element)
10832 (fill_composite_glyph_string): Add comments about special meaning
10833 of TAB characters in a composition.
10835 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10837 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
10838 This occurs when processing a multibyte format.
10839 Problem reported by Wolfgang Jenker.
10841 2011-09-15 Johan Bockgård <bojohan@gnu.org>
10843 * xdisp.c (try_cursor_movement): Only check for exact match if
10844 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
10846 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10848 Remove unused external symbols.
10849 * dispextern.h (calc_pixel_width_or_height): Remove decl.
10850 * xdisp.c (calc_pixel_width_or_height): Now static.
10851 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
10852 * indent.c (check_display_width):
10853 * w32term.c: Fix comment to match code.
10854 * xterm.c, xterm.h (x_catching_errors): Remove.
10856 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10858 * xselect.c: Use signed conversions more consistently (Bug#9498).
10859 (selection_data_to_lisp_data): Assume incoming selection data are
10860 signed integers, not unsigned. This is to be consistent with
10861 outgoing selection data, which was modified to use signed integers
10862 in as part of the fix to Bug#9196 in response to Jan D.'s comment
10863 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
10864 expects long, not unsigned long.
10866 2011-09-14 Eli Zaretskii <eliz@gnu.org>
10868 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
10869 computation of loop end. Reported by Johan Bockgård
10872 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
10874 * frame.c (Fother_visible_frames_p): Function deleted.
10876 2011-09-12 Eli Zaretskii <eliz@gnu.org>
10878 * indent.c (compute_motion): Process display vector front to back
10879 rather than the other way around. (Bug#2496)
10881 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
10883 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
10885 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
10887 * minibuf.c (Fread_from_minibuffer): Doc fix.
10889 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10891 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
10892 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
10894 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
10896 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
10897 value for non-existent files.
10899 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10901 * fileio.c (Finsert_file_contents): If the file cannot be opened,
10902 set its "size" to -1. This will set the modtime_size field of
10903 the corresponding buffer to -1, which is what
10904 verify-visited-file-modtime expects for files that do not exist.
10907 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
10909 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
10911 * lisp.h: ... from here. push_key_description is no longer
10912 defined in keyboard.c, so its declaration should not be in
10913 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
10914 logically belongs with push_key_description.
10916 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
10918 * buffer.h: Include <sys/types.h> instead of <time.h>.
10919 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
10920 Problem reported by Herbert J. Skuhra.
10922 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
10924 * xml.c (parse_region): Make the parsing work for
10925 non-comment-starting XML files again (bug#9144).
10927 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
10929 * image.c (gif_load): Fix calculation of bottom and right corner.
10932 2011-09-10 Eli Zaretskii <eliz@gnu.org>
10934 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
10935 redisplay in small windows.
10937 2011-09-09 Eli Zaretskii <eliz@gnu.org>
10939 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
10941 2011-09-08 Martin Rudalics <rudalics@gmx.at>
10943 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
10944 Operate on live windows only.
10946 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
10948 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
10950 2011-09-07 Eli Zaretskii <eliz@gnu.org>
10952 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
10953 only under bidi iteration.
10955 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
10957 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
10959 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10961 isnan: Fix porting problem to Solaris 10 with bundled gcc.
10962 Without this fix, the command to link temacs failed due to an
10963 undefined symbol __builtin_isnan. This is because
10964 /usr/include/iso/math_c99.h #defines isnan(x) to
10965 __builtin_isnan(x), but the bundled gcc, which identifies itself
10966 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
10968 * floatfns.c (isnan): #undef, and then #define to a clone of
10970 (Fisnan): Always define, since it's always available now.
10971 (syms_of_floatfns): Always define isnan at the Lisp level.
10973 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10975 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
10977 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10979 * fileio.c: Fix bugs with large file offsets (Bug#9428).
10980 The previous code assumed that file offsets (off_t values) fit in
10981 EMACS_INT variables, which is not true on typical 32-bit hosts.
10982 The code messed up by falsely reporting buffer overflow in cases
10983 such as (insert-file-contents "big" nil 1 2) into an empty buffer
10984 when "big" contains more than 2**29 bytes, even though this
10985 inserts just one byte and does not overflow the buffer.
10986 (Finsert_file_contents): Store file offsets as off_t
10987 values, not as EMACS_INT values. Check for overflow when
10988 converting between EMACS_INT and off_t. When checking for
10989 buffer overflow or for overlap, take the offsets into account.
10990 Don't use EMACS_INT for small values where int suffices.
10991 When checking for overlap, fix a typo: ZV was used where
10992 ZV_BYTE was intended.
10993 (Fwrite_region): Don't assume off_t fits into 'long'.
10994 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
10996 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
10998 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
11000 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
11002 sprintf-related integer and memory overflow issues (Bug#9412).
11004 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
11005 (esprintf, exprintf, evxprintf): New functions.
11006 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
11007 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
11008 (modify_event_symbol): Do not assume that the length of
11009 name_alist_or_stem is safe to alloca and fits in int.
11010 (Fexecute_extended_command): Likewise for function name and binding.
11011 (Frecursion_depth): Wrap around reliably on integer overflow.
11012 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
11013 since some callers pass EMACS_INT values.
11014 (Fsingle_key_description): Don't crash if symbol name contains more
11015 than MAX_ALLOCA bytes.
11016 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
11017 (get_minibuffer): Arg is now EMACS_INT, not int.
11018 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
11019 (esprintf, exprintf, evxprintf): New decls.
11020 * window.h (command_loop_level, minibuf_level): Reflect API changes.
11022 * dbusbind.c (signature_cat): New function.
11023 (xd_signature, Fdbus_register_signal):
11024 Do not overrun buffer; instead, report string overflow.
11026 * dispnew.c (add_window_display_history): Don't overrun buffer.
11027 Truncate instead; this is OK since it's just a log.
11029 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
11030 even if the time zone offset is outlandishly large.
11031 Don't mishandle offset == INT_MIN.
11033 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
11034 when creating daemon; the previous buffer-overflow check was incorrect.
11036 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
11037 which has the guts of the old verror function.
11039 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
11040 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
11042 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
11043 (font_unparse_xlfd): Don't blindly alloca long strings.
11044 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
11045 fits in int, when using sprintf. Use single snprintf to count
11046 length of string rather than counting it via multiple sprintfs;
11047 that's simpler and more reliable.
11048 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
11049 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
11050 sprintf, in case result does not fit in int.
11052 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
11053 (fontset_from_font): Print it.
11055 * frame.c (tty_frame_count): Now printmax_t, not int.
11056 (make_terminal_frame, set_term_frame_name): Print it.
11057 (x_report_frame_params): In X, window IDs are unsigned long,
11058 not signed long, so print them as unsigned.
11059 (validate_x_resource_name): Check for implausibly long names,
11060 and don't assume name length fits in 'int'.
11061 (x_get_resource_string): Don't blindly alloca invocation name;
11062 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
11065 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
11066 (xg_check_special_colors, xg_set_geometry):
11067 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
11069 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
11070 Use esprintf, not sprintf, in case result does not fit in int.
11072 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11073 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
11074 it as a large positive number.
11075 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
11076 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11078 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
11079 in case result does not fit in int.
11081 * print.c (float_to_string): Detect width overflow more reliably.
11082 (print_object): Make sprintf buffer a bit bigger, to avoid potential
11083 buffer overrun. Don't assume list length fits in 'int'. Treat
11084 print length of 0 as 0, not as infinity; to be consistent with other
11085 uses of print length in this function. Don't overflow print length
11086 index. Don't assume hash table size fits in 'long', or that
11087 vectorlike size fits in 'unsigned long'.
11089 * process.c (make_process): Use printmax_t, not int, to format
11090 process-name gensyms.
11092 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
11094 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
11095 to avoid potential buffer overrun.
11097 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
11098 if X resource line is longer than 512 bytes.
11100 * xfns.c (x_window): Make sprintf buffer a bit bigger
11101 to avoid potential buffer overrun.
11103 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
11105 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
11107 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
11109 Integer overflow fixes for scrolling, etc.
11110 Without these, Emacs silently mishandles large integers sometimes.
11111 For example, "C-u 4294967297 M-x recenter" was treated as if
11112 it were "C-u 1 M-x recenter" on a typical 64-bit host.
11114 * xdisp.c (try_window_id): Check Emacs fixnum range before
11115 converting to 'int'.
11117 * window.c (window_scroll_line_based, Frecenter):
11118 Check that an Emacs fixnum is in range before assigning it to 'int'.
11119 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
11120 values converted from Emacs fixnums.
11121 (Frecenter): Don't wrap around a line count if it is out of 'int'
11122 range; instead, treat it as an extreme value.
11123 (Fset_window_configuration, compare_window_configurations):
11124 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
11126 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
11127 that can exceed INT_MAX. Check that EMACS_INT value is in range
11128 before assigning it to the (possibly-narrower) index.
11129 (match_limit): Don't assume that a fixnum can fit in 'int'.
11131 * print.c (print_object): Use ptrdiff_t, not int, for index that can
11134 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
11135 (Fvertical_motion): Don't wrap around LINES values that don't fit
11136 in 'int'. Instead, treat them as extreme values. This is good
11137 enough for windows, which can't have more than INT_MAX lines anyway.
11139 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
11141 * Require libxml/parser.h to avoid compilation warning.
11143 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
11145 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
11146 since this reportedly can destroy thread storage.
11148 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
11150 * syntax.c (find_defun_start): Update all cache variables if
11151 exiting early (Bug#9401).
11153 2011-08-30 Eli Zaretskii <eliz@gnu.org>
11155 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
11157 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
11158 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
11159 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
11161 * term.c (tty_append_glyph): New function.
11162 (produce_stretch_glyph): Static function and its prototype deleted.
11164 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
11167 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
11169 * image.c (parse_image_spec): Check for nonnegative, not for positive,
11170 when checking :margin (Bug#9390).
11171 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
11172 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
11173 so that the name doesn't mislead. All uses changed.
11175 2011-08-28 Johan Bockgård <bojohan@gnu.org>
11177 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
11180 2011-08-27 Eli Zaretskii <eliz@gnu.org>
11182 * xdisp.c (move_it_to): Don't bail out early when reaching
11183 position beyond to_charpos, if we are scanning backwards.
11184 (move_it_vertically_backward): When DY == 0, make sure we get to
11185 the first character in the line after the newline.
11187 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
11189 * ccl.c: Improve and simplify overflow checking (Bug#9196).
11190 (ccl_driver): Do not generate an out-of-range pointer.
11191 (Fccl_execute_on_string): Remove unnecessary check for
11192 integer overflow, noted by Stefan Monnier in
11193 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
11194 Remove a FIXME that didn't need fixing.
11195 Simplify the newly-introduced buffer reallocation code.
11197 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
11199 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
11201 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
11203 Integer and memory overflow issues (Bug#9196).
11205 * doc.c (get_doc_string): Rework so that
11206 get_doc_string_buffer_size is the actual buffer size, rather than
11207 being 1 less than the actual buffer size; this makes xpalloc more
11210 * image.c (x_allocate_bitmap_record, cache_image):
11211 * xselect.c (Fx_register_dnd_atom):
11212 Simplify previous changes by using xpalloc.
11214 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
11215 since either will do and ptrdiff_t is convenient with xpalloc.
11217 * charset.c (charset_table_size)
11218 (struct charset_sort_data.priority): Now ptrdiff_t.
11219 (charset_compare): Don't overflow if priorities differ greatly.
11220 (Fsort_charsets): Don't assume list length fits in int.
11221 Check for size-calculation overflow when allocating sort data.
11222 (syms_of_charset): Allocate an initial charset table that is
11223 just under 64 KiB, to avoid problems with glibc malloc and mmap.
11225 * cmds.c (internal_self_insert): Check for size-calculation overflow.
11227 * composite.h (struct composition.glyph_len): Now int, not unsigned.
11228 The actual value is always <= INT_MAX, and leaving it unsigned made
11229 overflow checking harder.
11231 * dispextern.h (struct glyph_matrix.rows_allocated)
11232 (struct face_cache.size): Now ptrdiff_t, for convenience in use
11233 with xpalloc. The values are still always <= INT_MAX.
11235 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
11237 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
11238 (SAFE_NALLOCA): New macro.
11240 * region-cache.c (struct boundary.pos, find_cache_boundary)
11241 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
11242 (set_cache_region, invalidate_region_cache)
11243 (revalidate_region_cache, know_region_cache, region_cache_forward)
11244 (region_cache_backward, pp_cache):
11245 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
11246 so that ptrdiff_t * can be passed to xpalloc.
11247 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
11248 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
11249 (pp_cache): Don't assume cache_len fits in int.
11250 * region-cache.h: Adjust extern decls to match.
11252 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
11253 EMACS_INT, since either will do, for xpalloc.
11255 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
11256 (xnmalloc, xnrealloc, xpalloc): New functions.
11258 * bidi.c (bidi_shelve_header_size): New constant.
11259 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
11260 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
11262 * bidi.c (bidi_cache_shrink):
11263 * buffer.c (overlays_at, overlays_in, record_overlay_string)
11265 Don't update size of array until after memory allocation succeeds,
11266 because xmalloc/xrealloc may not return.
11267 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
11268 now that we have proper integer overflow checking.
11269 (record_overlay_string, overlay_strings): Catch overflows when
11270 calculating size of overlay_str_buf.
11272 * callproc.c (Fcall_process): Check for size overflow when
11273 calculating size of args2.
11274 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
11275 Normally we prefer signed values, but sticking with ptrdiff_t would
11276 require adding more-complicated checks.
11278 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
11279 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
11280 Redo buffer-overflow calculations to avoid integer overflow.
11281 Add a FIXME comment where memory seems to be over-allocated.
11283 * character.c (Fstring): Check for size-calculation overflow.
11285 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
11286 unnecessary integer overflow. Check for size overflow.
11287 (encode_coding_object): Don't update size until xmalloc succeeds.
11289 * composite.c (get_composition_id): Check for overflow in glyph
11290 length calculations.
11292 Integer and memory overflow fixes for display code.
11293 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
11294 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
11295 (scrolling_window): Check for overflow in size calculations.

11307 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
11308 (get_doc_string): Check for size calculation overflow.
11309 Don't update size until allocation succeeds.
11310 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
11311 EMACS_INT, where ptrdiff_t will do.
11312 (Fsubstitute_command_keys): Check for string overflow.
11314 * editfns.c (set_time_zone_rule): Don't assume environment length
11316 (message_length): Now ptrdiff_t, not int.
11317 (Fmessage_box): Don't update size until allocation succeeds.
11318 Don't assume message length fits in int.
11319 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
11321 * emacs.c (main): Do not reallocate argv, since there is a null at
11322 the end that can be overwritten, and this way there's no need to
11323 worry about size-calculation overflow.
11324 (sort_args): Check for size-calculation overflow.
11326 * eval.c (init_eval_once, grow_specpdl): Don't update size until
11328 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
11330 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
11331 (x_set_scroll_bar_width, x_figure_window_size):
11332 Check for integer overflow.
11333 (x_set_alpha): Do not assume XINT fits in int.
11335 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
11336 This is for the members text_lines, text_cols, total_lines, total_cols,
11337 where the system imposes an 'int' limit.
11339 * fringe.c (Fdefine_fringe_bitmap):
11340 Don't update size until alloc works.
11342 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
11343 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
11345 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
11346 Check for size-calculation overflow.
11347 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
11348 do, as we prefer signed integers.
11349 (id_to_widget.max_size, id_to_widget.used)
11350 (xg_store_widget_in_map, xg_remove_widget_from_map)
11351 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
11352 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
11353 Use and return ptrdiff_t, not int.
11354 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
11355 * gtkutil.h: Change prototypes to match the above.
11357 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
11358 are duplicate now that they've been promoted to lisp.h.
11359 (x_allocate_bitmap_record, x_alloc_image_color)
11360 (make_image_cache, cache_image, xpm_load):
11361 Don't update size until alloc is done.

11372 Use ptrdiff_t, not int, to count maps.
11373 (read_char_minibuf_menu_prompt): Check for overflow in size
11374 calculations. Don't update size until allocation succeeds.
11375 Redo calculations to avoid overflow.
11376 * keyboard.h: Change prototypes to match the above.
11378 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
11380 (current_minor_maps): Check for size calculation overflow.
11381 * keymap.h: Change prototypes to match the above.
11383 * lread.c (read1, init_obarray): Don't update size until alloc done.
11385 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

11404 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
11405 for command line length. Do not attempt to address one before the
11406 beginning of an array, as that's not portable.
11408 * term.c (max_frame_lines): Remove; unused.
11409 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
11411 (encode_terminal_code, calculate_costs): Check for size
11412 calculation overflow.

11418 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
11419 subtracting pointers.
11420 (gobble_line): Check for overflow more carefully. Don't update size
11423 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
11424 Don't update size until alloc done.

11434 Use ptrdiff_t, not int, for sizes.
11435 (Finternal_make_lisp_face, cache_face):
11436 Check for size calculation overflow.
11437 (cache_face): Treat size calculation overflows as if they were
11438 memory exhaustion (the usual treatment), rather than aborting.
11440 * xfns.c (x_encode_text, x_set_name_internal)
11441 (Fx_change_window_property): Use ptrdiff_t, not int, to count
11442 sizes, since they can exceed INT_MAX in size. Check for size

11446 (xg_select): Check for size calculation overflow.
11447 Don't update size until alloc done.
11449 * xrdb.c (get_environ_db): Don't assume path length fits in int,
11450 as sprintf is limited to int lengths.
11452 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
11453 (X_LONG_MIN): New macros.
11454 Use them to make the following changes clearer.
11455 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
11456 This change doesn't affect the value now, but it may help remind
11457 future maintainers not to raise the value too much later.
11458 (SELECTION_QUANTUM): Remove, replacing with ...
11459 (selection_quantum): ... new function, which avoids overflow.
11461 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
11462 assumption that selection length fits in 'int'.
11463 (x_reply_selection_request, x_handle_selection_request)
11464 (x_get_window_property, receive_incremental_selection)
11465 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
11466 (lisp_data_to_selection_data, clean_local_selection_data):
11467 Use ptrdiff_t, not int, to record length of selection.
11468 (x_reply_selection_request, x_get_window_property)

11470 Redo calculations to avoid overflow.
11471 (x_reply_selection_request): When sending hint, ceiling it at
11472 X_LONG_MAX rather than relying on wraparound overflow to send
11474 (x_get_window_property, receive_incremental_selection)
11475 (lisp_data_to_selection_data, x_property_data_to_lisp):
11476 Check for size-calculation overflow.
11477 (x_get_window_property, receive_incremental_selection)
11478 (lisp_data_to_selection_data, Fx_register_dnd_atom):
11479 Don't store size until memory allocation succeeds.
11480 (x_get_window_property): Plug memory leak on memory exhaustion.
11481 Don't double-block input; malloc is safe here. Don't assume 2**34
11482 - 4 fits in unsigned long. Add an xassert to check
11483 XGetWindowProperty overflow. Be more careful about overflow
11484 calculations, and distinguish size from memory overflow better.
11485 (receive_incremental_selection): When tracing, don't assume
11486 unsigned int is less than INT_MAX.
11487 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
11488 harmful) conversions of unsigned short to int.
11489 (lisp_data_to_selection_data): Don't assume that integers
11490 in the range -65535 through -1 fit in an X unsigned short.
11491 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
11492 result parameters unless successful. Rely on cons_to_unsigned
11493 to report problems with elements; the old code wasn't right anyway.
11494 (x_check_property_data): Check for int overflow; we cannot use
11495 a wider type due to X limits.
11496 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
11498 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
11500 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
11501 (x_term_init): Check for size calculation overflow.
11502 (x_color_cells): Don't store size until memory allocation succeeds.
11503 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
11504 Don't assume alloca size is less than MAX_ALLOCA.
11505 (x_term_init): Don't assume length fits in int (sprintf is limited
11508 Use ptrdiff_t for composition IDs.

11528 * lisp.h (hash_lookup, hash_put):
11529 * minibuf.c (Ftest_completion):
11530 Use ptrdiff_t for hash table indexes, not int (which is too
11531 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
11532 32-bit --with-wide-int hosts).
11534 * charset.c (Fdefine_charset_internal): Check for integer overflow.
11535 Add a FIXME comment about memory leaks.
11536 (syms_of_charset): Don't assume xmalloc returns.
11538 Don't assume that stated character widths fit in int.
11539 * character.c (Fchar_width, c_string_width, lisp_string_width):
11540 * character.h (CHAR_WIDTH):
11541 * indent.c (MULTIBYTE_BYTES_WIDTH):
11542 Use sanitize_char_width to avoid undefined and/or bad behavior
11543 with outlandish widths.
11544 * character.h (sanitize_tab_width): Rename from sanitize_width,
11545 now that we have two such functions. All uses changed.
11546 (sanitize_char_width): New inline function.
11548 Don't assume that tab-width fits in int.
11549 * character.h (sanitize_width): New inline function.

11556 * fileio.c: Integer overflow issues with file modes.
11557 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
11559 * charset.c (read_hex): New arg OVERFLOW. All uses changed.

11564 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
11565 (x_send_scroll_bar_event): Likewise. Check that the size does not
11566 exceed limits imposed by XClientMessageEvent, as well as the usual
11567 ptrdiff_t and size_t limits.
11569 * keyboard.c: Overflow, signedness and related fixes.
11570 (make_lispy_movement): Use same integer type in forward decl
11571 that is used in the definition.
11572 (read_key_sequence, keyremap_step):
11573 Change bufsize argument back to int, undoing my 2011-03-30 change.
11574 We prefer signed types, and int is wide enough here.
11575 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
11576 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
11577 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
11578 length, not size_t. Use ptrdiff_t for index, not int.
11579 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
11580 possibility of integer overflow.
11582 Overflow, signedness and related fixes for images.
11584 * dispextern.h (struct it.stack[0].u.image.image_id)
11585 (struct_it.image_id, struct image.id, struct image_cache.size)

11592 * xdisp.c (calc_pixel_width_or_height):
11593 * xfns.c (image_cache_refcount):
11594 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
11595 on typical 64-bit hosts.

11603 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
11604 (lookup_image): Remove unnecessary tests.
11605 (xbm_image_p): Locals are now of int, not EMACS_INT,
11606 since parse_image_check makes sure they fit into int.
11607 (png_load, gif_load, svg_load_image):
11608 Prefer int to unsigned where either will do.
11609 (tiff_handler): New function, combining the cores of the
11610 old tiff_error_handler and tiff_warning_handler.
11611 This function is rewritten to use vsnprintf and thereby avoid
11612 stack buffer overflows. It uses only the features of vsnprintf
11613 that are common to both POSIX and native Microsoft.
11614 (tiff_error_handler, tiff_warning_handler): Use it.
11615 (tiff_load, gif_load, imagemagick_load_image):
11616 Don't assume :index value fits in 'int'.
11617 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
11618 (imagemagick_load_image): Check that crop parameters fit into
11619 the integer types that MagickCropImage accepts. Don't assume
11620 Vimagemagick_render_type has a nonnegative value. Don't assume
11621 size_t fits in 'long'.
11622 (gs_load): Use printmax_t to print the widest integers possible.
11623 Check for integer overflow when computing image height and width.
11625 2011-08-26 Eli Zaretskii <eliz@gnu.org>

11636 (handle_single_display_spec): If the display spec is of the form
11637 `(space ...)', and specifies display in the text area, return 2
11639 (try_cursor_movement): Check for the need to scroll more
11640 accurately, and prefer exact match for point under bidi.
11641 Don't advance `row' beyond the last row of the window.

11662 positioning on the newline at EOL of R2L text within L2R
11663 paragraph, and vice versa.
11664 (try_cursor_movement): Check continued rows, in addition to
11665 continuation rows. Fixes unwarranted scroll when point enters a
11666 continued line of R2L text within an L2R paragraph, or vice versa.

11694 * xdisp.c (redisplay_window): When computing centering_position,
11695 account for the height of the header line. (Bug#8874)
11697 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
11698 instead of CHAR_TO_BYTE. Fixes a crash when a completion
11699 candidate is selected by the mouse, and that candidate has a
11700 composed character under the mouse.
11702 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
11703 coordinates reported by pos-visible-in-window-p for a composed
11704 character in column zero.
11706 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

11713 consider it a hit if to_charpos is anywhere in the range of the
11714 composed buffer positions.
11716 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
11718 * image.c (gif_load): Don't assume that each subimage has the same
11719 dimensions as the base image. Handle disposal method that is
11720 "undefined" by the gif spec (Bug#9335).
11722 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
11724 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

11730 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
11731 from an Org mode buffer to a Speedbar frame.
11733 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
11734 a composition, take its buffer position from IT->cmp_it.charpos.
11735 Fixes cursor positioning at the beginning of a line that begins
11736 with a composed character.
11738 2011-08-18 Eli Zaretskii <eliz@gnu.org>
11740 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
11741 character bidirectional type, use STRONG_L instead. Fixes crashes
11742 in a buffer produced by `describe-categories'.
11744 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
11745 members before the level stack, so they would be saved and
11746 restored when copying iterator state. Fixes incorrect reordering
11747 around TABs covered by display properties.

11837 * nsterm.m (sendEvent): If event is NSApplicationDefined and
11838 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit

11883 the iterator structure wrt the object coming from a display
11884 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
11885 properties. (Bug#9284)

12105 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
12106 In other words, assume that every image size is allowed, on non-X
12107 hosts. This assumption is probably wrong, but it lets Emacs compile.
12109 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
12111 * regex.c (re_iswctype): Convert return values to boolean.
12113 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
12115 * xdisp.c (compute_display_string_pos): Don't use cached display
12116 string position if the buffer had its restriction changed.
12119 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12121 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12123 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12125 Integer signedness and overflow and related fixes. (Bug#9079)
12127 * bidi.c: Integer size and overflow fixes.
12128 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
12129 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
12130 (bidi_cache_find_level_change, bidi_cache_ensure_space)
12131 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
12132 (bidi_find_other_level_edge):
12133 Use ptrdiff_t instead of EMACS_INT where either will do.
12134 This works better on 32-bit hosts configured --with-wide-int.
12135 (bidi_cache_ensure_space): Check for size-calculation overflow.
12136 Use % rather than repeated addition, for better worst-case speed.
12137 Don't set bidi_cache_size until after xrealloc returns, because it
12139 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
12140 (bidi_cache_ensure_space): Also check that the bidi cache size
12141 does not exceed that of the largest Lisp string or buffer. See Eli
12142 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
12144 * alloc.c (__malloc_size_t): Remove.
12145 All uses replaced by size_t. See Andreas Schwab's note
12146 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
12148 * image.c: Improve checking for integer overflow.
12149 (check_image_size): Assume that f is nonnull, since
12150 it is always nonnull in practice. This is one less thing to
12151 worry about when checking for integer overflow later.
12152 (x_check_image_size): New function, which checks for integer
12153 overflow issues inside X.
12154 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
12155 This removes the need for a memory_full check.
12156 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
12157 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
12158 (xbm_read_bitmap_data): Change locals back to 'int', since
12159 their values must fit in 'int'.
12160 (xpm_load_image, png_load, tiff_load):
12161 Invoke x_create_x_image_and_pixmap earlier,
12162 to avoid much needless work if the image is too large.
12163 (tiff_load): Treat overly large images as if
12164 x_create_x_image_and_pixmap failed, not as malloc failures.
12165 (gs_load): Use x_check_image_size.
12167 * gtkutil.c: Omit integer casts.
12168 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
12169 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
12171 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
12173 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
12174 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
12175 would wrongly return t on a 64-bit host.
12177 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
12178 The plain *_OVERFLOW macros run afoul of GCC bug 49705
12179 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
12180 and therefore cause GCC to emit a bogus diagnostic in some cases.
12182 * image.c: Integer signedness and overflow and related fixes.
12183 This is not an exhaustive set of fixes, but it's time to
12184 record what I've got.
12185 (lookup_pixel_color, check_image_size): Remove redundant decls.
12186 (check_image_size): Don't assume that arbitrary EMACS_INT values
12187 fit in 'int', or that arbitrary 'double' values fit in 'int'.
12188 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
12189 (tiff_load, imagemagick_load_image):
12190 Check for overflow in size calculations.
12191 (x_create_x_image_and_pixmap): Remove unnecessary test for
12192 xmalloc returning NULL; that can't happen.
12193 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
12194 (xpm_color_bucket): Use better integer hashing function.
12195 (xpm_cache_color): Don't possibly over-allocate memory.
12196 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
12197 (gif_memory_source):
12198 Use ptrdiff_t, not int or size_t, to record sizes.
12199 (png_load): Don't assume values greater than 2**31 fit in 'int'.
12200 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
12201 either works, as we prefer signed integers.
12202 (tiff_read_from_memory, tiff_write_from_memory):
12203 Return tsize_t, not size_t, since that's what the TIFF API wants.
12204 (tiff_read_from_memory): Don't fail simply because the read would
12205 go past EOF; instead, return a short read.
12206 (tiff_load): Omit no-longer-needed casts.
12207 (Fimagemagick_types): Don't assume size fits into 'int'.
12209 Improve hashing quality when configured --with-wide-int.
12210 * fns.c (hash_string): New function, taken from sxhash_string.
12211 Do not discard information about ASCII character case; this
12212 discarding is no longer needed.
12213 (sxhash-string): Use it. Change sig to match it. Caller changed.
12214 * lisp.h: Declare it.
12215 * lread.c (hash_string): Remove, since we now use fns.c's version.
12216 The fns.c version returns a wider integer if --with-wide-int is
12217 specified, so this should help the quality of the hashing a bit.
12219 * emacs.c: Integer overflow minor fix.
12220 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
12221 Define only if GNU_LINUX.
12222 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
12224 * dispnew.c: Integer signedness and overflow fixes.
12225 Remove unnecessary forward decls, that were a maintenance hassle.
12226 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
12228 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
12229 (scrolling_window): Use ptrdiff_t, not int, for byte count.
12230 (prepare_desired_row, line_draw_cost):
12231 Use int, not unsigned, where either works.
12232 (save_current_matrix, restore_current_matrix):
12233 Use ptrdiff_t, not size_t, where either works.
12234 (init_display): Check for overflow more accurately, and without
12235 relying on undefined behavior.
12237 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
12238 Remove, replacing with the new symbols in lisp.h. All uses changed.
12239 * fileio.c (make_temp_name):
12240 * filelock.c (lock_file_1, lock_file):
12241 * xdisp.c (message_dolog):
12242 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
12243 Use pMd etc. instead.
12244 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
12245 replacing the pWIDE etc. symbols removed from editfns.c.
12247 * keyboard.h (num_input_events): Now uintmax_t.
12248 This is (very slightly) less likely to mess up due to wraparound.
12251 * buffer.c: Integer signedness fixes.
12252 (alloc_buffer_text, enlarge_buffer_text):
12253 Use ptrdiff_t rather than size_t when either will do, as we prefer
12256 * alloc.c: Integer signedness and overflow fixes.
12257 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
12258 (__malloc_size_t): Default to size_t, not to int.
12259 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
12260 (Fgarbage_collect, mark_object_loop_halt, mark_object):
12261 Prefer ptrdiff_t to size_t when either would do, as we prefer
12263 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
12264 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
12265 Now const. Initialize with values that are in range even if char
12267 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
12268 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
12269 These functions do the right thing with sizes > 2**32.
12270 (check_depth): Now ptrdiff_t, not int.
12271 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
12272 Adjust to new way of storing sizes. Check for size overflow bugs
12274 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
12275 slightly wrong anyway, as it missed one instance of
12276 XMALLOC_OVERRUN_CHECK_OVERHEAD.
12277 (refill_memory_reserve): Omit needless cast to size_t.
12278 (mark_object_loop_halt): Mark as externally visible.
12280 * xselect.c: Integer signedness and overflow fixes.
12281 (Fx_register_dnd_atom, x_handle_dnd_message):
12282 Use ptrdiff_t, not size_t, since we prefer signed.
12283 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
12284 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
12285 x_dnd_atoms_size and x_dnd_atoms_length.
12287 * doprnt.c: Prefer signed to unsigned when either works.
12289 * doprnt.c (doprnt):
12291 * xdisp.c (vmessage):
12292 Use ptrdiff_t, not size_t, when using or implementing doprnt,
12293 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
12294 prefer signed arithmetic to avoid comparison confusion.
12295 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
12296 but is a bit tricky.
12298 Assume freestanding C89 headers, string.h, stdlib.h.
12299 * data.c, doprnt.c, floatfns.c, print.c:
12300 Include float.h unconditionally.
12301 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
12302 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
12303 * regex.c: Likewise for stddef.h, string.h.
12304 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
12305 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
12306 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
12307 (STDC_HEADERS): Remove obsolete defines.
12308 * sysdep.c: Include limits.h unconditionally.
12310 Assume support for memcmp, memcpy, memmove, memset.
12311 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
12312 * regex.c (memcmp, memcpy):
12313 Remove; we assume C89 now.
12315 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
12316 (__malloc_safe_bcopy): Remove; no longer needed.
12318 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
12319 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
12320 well either way, and we prefer signed to unsigned.
12322 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
12324 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
12325 closes the connection while we're reading (bug#9182).
12327 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
12329 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
12330 are specified (Bug#9168).
12332 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
12334 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
12335 Found by GCC static checking and --with-wide-int on a 32-bit host.
12337 2011-07-25 Eli Zaretskii <eliz@gnu.org>
12339 * xdisp.c (compute_display_string_pos): Fix logic of caching
12340 previous display string position. Initialize cached_prev_pos to
12341 -1. Fixes slow-down at the beginning of a buffer.
12343 2011-07-24 Eli Zaretskii <eliz@gnu.org>
12345 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
12346 for attrs[LFACE_FONTSET_INDEX].
12348 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
12350 * xml.c (parse_region): Remove unused local
12351 that was recently introduced.
12353 2011-07-23 Eli Zaretskii <eliz@gnu.org>
12355 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
12356 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
12358 * xdisp.c (move_it_in_display_line_to): Record the best matching
12359 position for TO_CHARPOS while scanning the line, and restore it on
12360 exit if none of the characters scanned was an exact match.
12361 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
12362 when exact match is impossible due to invisible text, and the
12363 lines are truncated.
12365 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
12367 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
12370 2011-07-22 Eli Zaretskii <eliz@gnu.org>
12372 Fix a significant slow-down of cursor motion with C-n, C-p,
12373 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
12374 auto-repeat under bidi redisplay in fontified buffers.
12375 * xdisp.c (compute_stop_pos_backwards): New function.
12376 (next_element_from_buffer): Call compute_stop_pos_backwards to
12377 find a suitable prev_stop when we find ourselves before
12379 (reseat): Don't look for prev_stop, as that could mean a very long
12381 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
12382 <cached_disp_overlay_modiff>: Cache for last found display string
12384 (compute_display_string_pos): Return the cached position if asked
12385 about the same buffer in the same area of character positions, and
12386 the buffer wasn't changed since the time the display string
12387 position was cached.
12389 2011-07-22 Eli Zaretskii <eliz@gnu.org>
12391 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
12392 is an integer, which is important for empty lines. (Bug#9149)
12394 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
12396 * frame.c (Fmodify_frame_parameters): In tty case, update the
12397 default face if necessary (Bug#4238).
12399 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
12401 * editfns.c (Fstring_to_char): No need to explain what a character
12402 is in the docstring (Bug#6576).
12404 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
12406 * xml.c (parse_region): Make sure we always return a tree.
12408 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
12410 * xml.c (parse_region): If a document contains only comments,
12413 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
12415 * xml.c (make_dom): Return comments, too.
12417 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
12420 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
12421 and the surrounding thread.
12422 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
12423 rather than fgets, and retry after EINTR. Otherwise, 'emacs
12424 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
12426 * s/openbsd.h (BROKEN_SIGIO): Define.
12427 * unexelf.c (unexec) [__OpenBSD__]:
12428 Don't update the .mdebug section of the Alpha COFF symbol table.
12430 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12432 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
12435 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
12437 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
12438 This fixes some race conditions on the permissions of any newly
12441 * alloc.c (valid_pointer_p): Use pipe, not open.
12442 This fixes some permissions issues when debugging.
12444 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
12445 If fchown fails to set both uid and gid, try to set just gid,
12446 as that is sometimes allowed. Adjust the file's mode to eliminate
12447 setuid or setgid bits that are inappropriate if fchown fails.
12449 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
12451 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
12452 to compare Lisp_Objects.
12453 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
12454 global_gnutls_log_level, don't mistake it for a Lisp_Object.
12455 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
12457 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
12459 * lread.c (read_integer): Unread even EOF character.
12460 (read1): Likewise. Properly record start position of symbol.
12462 * lread.c (read1): Read `#:' as empty uninterned symbol if no
12463 symbol character follows.
12465 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
12467 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
12468 This works around a problem with the previous change to Fcopy_file.
12469 Recent glibc declares fchown with __attribute__((warn_unused_result)),
12470 and without this change, GCC might complain about discarding
12471 fchown's return value.
12473 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
12475 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
12477 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
12479 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
12481 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
12483 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
12484 it's used from the C level.
12486 * process.c: Use the same condition for POLL_FOR_INPUT in both
12487 keyboard.c and process.c (bug#1858).
12489 2011-07-09 Lawrence Mitchell <wence@gmx.li>
12491 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
12492 (Fgnutls_boot): Use it.
12494 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
12496 * doc.c (Fsubstitute_command_keys): Revert last change.
12498 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
12500 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
12501 quotes the next character, and doesn't affect other longer
12502 sequences (bug#8935).
12504 * lread.c (syms_of_lread): Clarify that is isn't only
12505 `eval-buffer' and `eval-defun' that's affected by
12506 `lexical-binding' (bug#8460).
12508 2011-07-15 Eli Zaretskii <eliz@gnu.org>
12510 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
12511 bidi redisplay when a line includes both an image and is truncated.
12513 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
12515 Fix minor problems found by static checking.
12516 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
12517 (elsz): Now a signed constant, not a size_t var. We prefer signed
12518 types to unsigned, to avoid integer comparison confusion. Without
12519 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
12520 "cannot optimize loop, the loop counter may overflow", a symptom
12522 * indent.c (Fvertical_motion): Mark locals as initialized.
12523 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
12525 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
12527 * search.c (Fre_search_backward): Mention `case-fold-search' in
12528 all the re_search_* functions (bug#8138).
12530 * keyboard.c (Fopen_dribble_file): Document when the file is
12533 2011-07-14 Eli Zaretskii <eliz@gnu.org>
12535 * bidi.c (bidi_dump_cached_states): Fix format of displaying
12538 Support bidi reordering of display and overlay strings.
12539 * xdisp.c (compute_display_string_pos)
12540 (compute_display_string_end): Accept additional argument STRING.
12541 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
12542 (reseat_to_string): Initialize bidi_it->string.s and
12543 bidi_it->string.schars.
12544 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
12545 NULL (avoids a crash in bidi_paragraph_init).
12546 Initialize itb.string.lstring.

13047 (clone_per_buffer_values): Don't assume that

13049 This isn't true in general, and it's particularly not true
13050 if Emacs is configured with --with-wide-int.
13051 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
13052 New macros, used in the buffer.c change.

13088 Random fixes. E.g., (random) never returned negative values.
13089 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
13090 subseconds part to the entropy, as that's a bit more random.
13091 Prefer signed to unsigned, since the signedness doesn't matter and
13092 in general we prefer signed. When given a limit, use a
13093 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
13094 latter isn't right if USE_2_TAGS_FOR_INTS.
13095 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
13096 not 0..VALMASK. Don't discard "excess" bits that random () returns.
13098 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
13100 * textprop.c (text_property_stickiness):
13101 Obey Vtext_property_default_nonsticky.

13108 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
13109 This is more efficient than Ffile_directory_p and avoids a minor race.
13111 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
13113 * buffer.c (Foverlay_put): Say what the return value is
13116 * fileio.c (barf_or_query_if_file_exists): Check first if the file
13117 is a directory before asking whether to use the file name
13119 (barf_or_query_if_file_exists): Make the "File is a directory"
13120 error be more correct.
13122 * fns.c (Frequire): Remove the mention of the .gz files, since
13123 that's installation-specific, but keep the mention of
13124 `get-load-suffixes'.
13126 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
13128 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

13134 (syms_of_gnutls): Remove duplicate DEFSYM for
13135 Qgnutls_bootprop_verify_hostname_error, an error for
13136 Qgnutls_bootprop_verify_error (which is no longer used).
13138 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
13139 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
13140 Also (re)move comments that are misplaced or no longer relevant.
13142 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13144 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

13203 (syms_of_keymap): Defsubr make-composed-keymap.
13204 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

13241 * eval.c (struct backtrace): Simplify and port the data structure.
13242 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
13243 signed bit field, as this assumption is not portable and it makes
13244 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
13245 "char debug_on_exit : 1" as this is not portable either; instead,
13246 use the portable "unsigned int debug_on_exit : 1". Remove unused
13247 member evalargs. Remove obsolete comments about cc bombing out.
13249 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

13424 * keyboard.h (struct keyboard.kbd_macro_bufsize):
13425 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
13426 Use ptrdiff_t, not int, for sizes.
13427 Don't increment bufsize until after realloc succeeds.
13428 Check for size-calculation overflow.
13429 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
13431 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
13433 * lread.c: Integer overflow fixes.
13434 (read_integer): Radix is now EMACS_INT, not int,
13435 to improve quality of diagnostics for out-of-range radices.
13436 Calculate buffer size correctly for out-of-range radices.
13437 (read1): Check for integer overflow in radices, and in
13438 read-circle numbers.
13439 (read_escape): Avoid int overflow.
13440 (Fload, openp, read_buffer_size, read1)
13441 (substitute_object_recurse, read_vector, read_list, map_obarray):
13442 Use ptrdiff_t, not int, for sizes.
13443 (read1): Use EMACS_INT, not int, for sizes.
13444 Check for size overflow.
13446 * image.c (cache_image): Check for size arithmetic overflow.
13448 * lread.c: Integer overflow issues.
13449 (saved_doc_string_size, saved_doc_string_length)

13455 (read_escape): Check for hex character overflow.
13457 2011-06-22 Leo Liu <sdl.web@gmail.com>
13459 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
13460 Move to minibuffer.el.
13462 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
13464 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
13465 The following patches are for when GLYPH_DEBUG && !XASSERT.
13466 * dispextern.h (trace_redisplay_p, dump_glyph_string):
13467 * dispnew.c (flush_stdout):
13468 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
13469 Mark as externally visible.
13470 * dispnew.c (check_window_matrix_pointers): Now static.
13471 * dispnew.c (window_to_frame_vpos):
13472 * xfns.c (unwind_create_frame):
13473 * xterm.c (x_check_font): Remove unused local.
13474 * scroll.c (CHECK_BOUNDS):
13475 * xfaces.c (cache_fache): Rename local to avoid shadowing.
13476 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
13477 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
13478 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
13479 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
13481 (debug_method_add): Use va_list and vsprintf rather than relying
13482 on undefined behavior with wrong number of arguments.
13483 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
13484 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
13485 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
13486 since we're not interested in debugging glyphs with old libraries.
13487 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
13488 GCC 4.6.0's static checking.
13490 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
13492 Integer overflow and signedness fixes (Bug#8873).

13501 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
13502 (x_create_bitmap_from_xpm_data):
13503 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
13504 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
13506 * xfaces.c (load_pixmap):
13507 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
13508 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
13509 (.bitmaps_last, struct x_output.icon_bitmap):
13510 Use ptrdiff_t, not int, for bitmap indexes.
13511 (x_allocate_bitmap_record): Check for size overflow.
13512 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
13514 Use ptrdiff_t, not int, for overlay counts.
13515 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
13516 * editfns.c (overlays_around, get_pos_property):
13517 * textprop.c (get_char_property_and_overlay):
13518 * xdisp.c (next_overlay_change, note_mouse_highlight):
13519 * xfaces.c (face_at_buffer_position):
13520 * buffer.c (OVERLAY_COUNT_MAX): New macro.
13521 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
13522 (Fnext_overlay_change, Fprevious_overlay_change)
13523 (mouse_face_overlay_overlaps, Foverlays_in):
13524 Use ptrdiff_t, not int, for sizes.
13525 (overlays_at, overlays_in): Check for size-calculation overflow.
13527 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
13529 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
13530 (x_session_initialize): Do not assume string length fits in int.
13532 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
13533 This is unlikely, but can occur if DPI is outlandish.
13535 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
13536 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
13538 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
13539 * xrdb.c (magic_file_p, search_magic_path):
13540 Omit last arg SUFFIX; it was always 0. All callers changed.
13541 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
13543 * xfont.c (xfont_match): Avoid need for strlen.
13545 * xfns.c: Don't assume strlen fits in int.
13546 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
13548 * xdisp.c (message_log_check_duplicate): Return intmax_t,
13549 not unsigned long, as we prefer signed integers. All callers changed.
13550 Detect integer overflow in repeat count.
13551 (message_dolog): Don't assume print length fits in 39 bytes.
13552 (display_mode_element): Don't assume strlen fits in int.
13554 * termcap.c: Don't assume sizes fit in int and never overflow.
13555 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
13556 (gobble_line): Check for size-calculation overflow.
13558 * minibuf.c (Fread_buffer):
13559 * lread.c (intern, intern_c_string):
13560 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
13561 Don't assume string length fits in int.
13563 * keyboard.c (parse_tool_bar_item):
13564 * gtkutil.c (style_changed_cb): Avoid need for strlen.
13566 * font.c: Don't assume string length fits in int.
13567 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
13568 Use ptrdiff_t, not int.
13569 (font_intern_prop): Don't assume string length fits in int.
13570 Don't assume integer property fits in fixnum.
13571 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
13573 * filelock.c: Fix some buffer overrun and integer overflow issues.
13574 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
13575 Reformulate so as not to need the command string.
13576 Invoke gzip -cd rather than gunzip, as it's more portable.
13577 (lock_info_type, lock_file_1, lock_file):
13578 Don't assume pid_t and time_t fit in unsigned long.
13579 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
13580 (current_lock_owner): Prefer signed type for sizes.
13581 Use memcpy, not strncpy, where memcpy is what is really wanted.
13582 Don't assume (via atoi) that time_t and pid_t fit in int.
13583 Check for time_t and/or pid_t out of range, e.g., via a network share.
13584 Don't alloca where an auto var works fine.
13586 * fileio.c: Fix some integer overflow issues.
13587 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
13588 Don't assume string length fits in int.
13589 (directory_file_name): Don't assume string length fits in long.
13590 (make_temp_name): Don't assume pid fits in int, or that its print
13591 length is less than 20.
13593 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
13595 * coding.c (make_subsidiaries): Don't assume string length fits in int.
13597 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
13599 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
13600 We prefer signed integers, even for size calculations.
13602 * emacs.c: Don't assume string length fits in 'int'.
13603 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
13604 (main): Don't invoke strlen when not needed.
13606 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
13607 (XD_DEBUG_MESSAGE): Don't waste a byte.
13609 * callproc.c (getenv_internal_1, getenv_internal)
13610 (Fgetenv_internal):
13611 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
13613 * lread.c (invalid_syntax): Omit length argument.
13614 All uses changed. This doesn't fix a bug, but it simplifies the
13615 code away from its former Hollerith-constant appearance, and it's
13616 one less 'int' to worry about when looking at integer-overflow issues.
13617 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
13619 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
13620 This didn't break anything, but it didn't help either.
13621 It's confusing to put a bogus integer in a place where the actual
13622 value does not matter.
13623 (LIST_END_P): Remove unused macro and its bogus comment.
13624 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
13626 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
13627 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
13629 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
13630 We prefer signed types, and the value cannot exceed the EMACS_INT
13631 range anyway (because otherwise the length would not be representable).
13632 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
13633 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
13634 This avoids a GCC warning when WIDE_EMACS_INT.
13636 * indent.c (sane_tab_width): New function.
13637 (current_column, scan_for_column, Findent_to, position_indentation)
13638 (compute_motion): Use it. This is just for clarity.
13639 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
13641 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
13643 * lisp.h (lint_assume): New macro.
13644 * composite.c (composition_gstring_put_cache):
13645 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
13647 * editfns.c, insdel.c:
13648 Omit unnecessary forward decls, to simplify future changes.
13650 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
13652 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
13654 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
13655 Use much-faster test for byte-length change.
13656 Don't assume string byte-length fits in 'int'.
13657 Check that character arg fits in 'int'.
13658 (mapcar1): Declare byte as byte, for clarity.
13660 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
13662 * fns.c (concat): Catch string overflow earlier.
13663 Do not rely on integer wraparound.
13665 * dispextern.h (struct it.overlay_strings_charpos)
13666 (struct it.selective): Now EMACS_INT, not int.
13667 * xdisp.c (forward_to_next_line_start)
13668 (back_to_previous_visible_line_start)
13669 (reseat_at_next_visible_line_start, next_element_from_buffer):
13670 Don't arbitrarily truncate the value of 'selective' to int.
13672 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
13674 * composite.c: Don't truncate sizes to 'int'.
13675 (composition_gstring_p, composition_reseat_it)
13676 (composition_adjust_point): Use EMACS_INT, not int.
13677 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
13678 not EMACS_UINT, for indexes.
13680 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
13682 * buffer.c: Include <verify.h>.
13683 (struct sortvec.priority, struct sortstr.priority):
13684 Now EMACS_INT, not int.
13685 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
13686 (struct sortstr.size, record_overlay_string)
13687 (struct sortstrlist.size, struct sortlist.used):
13688 Don't truncate size to int.
13689 (record_overlay_string): Check for size-calculation overflow.
13690 (init_buffer_once): Check at compile-time, not run-time.
13692 2011-06-22 Jim Meyering <meyering@redhat.com>
13694 Don't leak an XBM-image-sized buffer
13695 * image.c (xbm_load): Free the image buffer after using it.
13697 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
13700 * composite.c (find_automatic_composition): Omit needless 'return 0;'
13701 that Sun C diagnosed.
13702 * fns.c (secure_hash): Fix pointer signedness issue.
13703 * intervals.c (static_offset_intervals): New function.
13704 (offset_intervals): Use it.
13706 2011-06-21 Leo Liu <sdl.web@gmail.com>
13709 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
13712 * fns.c (secure_hash): Rename from crypto_hash_function and change
13713 the first arg to accept symbols.
13714 (Fsecure_hash): New primitive.
13715 (syms_of_fns): New symbols.
13717 2011-06-20 Deniz Dogan <deniz@dogan.se>
13719 * process.c (Fset_process_buffer): Clarify return value in
13722 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
13724 * dispnew.c (add_window_display_history): Use BVAR.
13726 * xdisp.c (debug_method_add): Use BVAR.
13727 (check_window_end, dump_glyph_matrix, dump_glyph)
13728 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
13730 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
13733 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
13734 check till after the cache is created in init_frame_faces.
13736 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
13738 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
13740 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
13742 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
13743 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
13744 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
13746 Improve buffer-overflow checking (Bug#8873).
13747 * fileio.c (Finsert_file_contents):
13748 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
13749 Remove the old (too-loose) buffer overflow checks.
13750 They weren't needed, since make_gap checks for buffer overflow.
13751 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
13752 The old code merely checked for Emacs fixnum overflow, and relied
13753 on undefined (wraparound) behavior. The new code avoids undefined
13754 behavior, and also checks for ptrdiff_t and/or size_t overflow.
13756 * editfns.c (Finsert_char): Don't dump core with very negative counts.
13757 Tune. Don't use wider integers than needed. Don't use alloca.
13758 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
13760 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
13762 * insdel.c, lisp.h (buffer_overflow): New function.
13763 (insert_from_buffer_1, replace_range, replace_range_2):
13764 * insdel.c (make_gap_larger):
13765 * editfns.c (Finsert_char):
13766 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
13768 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
13770 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
13772 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
13774 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
13775 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
13777 * fileio.c: Don't assume EMACS_INT fits in off_t.
13778 (emacs_lseek): New static function.
13779 (Finsert_file_contents, Fwrite_region): Use it.
13780 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
13782 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
13784 * fns.c: Don't overflow int when computing a list length.
13785 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
13786 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
13787 truncation on 64-bit hosts. Check for QUIT every
13788 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
13789 faster and is responsive enough.
13790 (Flength): Report an error instead of overflowing an integer.
13791 (Fsafe_length): Return a float if the value is not representable
13792 as a fixnum. This shouldn't happen except in contrived situations.
13793 (Fnthcdr, Fsort): Don't assume list length fits in int.
13794 (Fcopy_sequence): Don't assume vector length fits in int.
13796 * alloc.c: Check that resized vectors' lengths fit in fixnums.
13797 (header_size, word_size): New constants.
13798 (allocate_vectorlike): Don't check size overflow here.
13799 (allocate_vector): Check it here instead, since this is the only
13800 caller of allocate_vectorlike that could cause overflow.
13801 Check that the new vector's length is representable as a fixnum.
13803 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
13804 The previous code was bogus. For example, next_almost_prime (32)
13805 returned 39, which is undesirable as it is a multiple of 3; and
13806 next_almost_prime (24) returned 25, which is a multiple of 5 so
13807 why was the code bothering to check for multiples of 7?
13809 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
13811 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
13813 Variadic C functions now count arguments with ptrdiff_t.
13814 This partly undoes my 2011-03-30 change, which replaced int with size_t.
13815 Back then I didn't know that the Emacs coding style prefers signed int.
13816 Also, in the meantime I found a few more instances where arguments
13817 were being counted with int, which may truncate counts on 64-bit
13818 machines, or EMACS_INT, which may be unnecessarily wide.
13819 * lisp.h (struct Lisp_Subr.function.aMANY)
13820 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
13821 Arg counts are now ptrdiff_t, not size_t.
13822 All variadic functions and their callers changed accordingly.
13823 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
13824 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
13825 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
13826 * callint.c (Fcall_interactively): Check arg count for overflow,
13827 to avoid potential buffer overrun. Use signed char, not 'int',
13828 for 'varies' array, so that we needn't bother to check its size
13829 calculation for overflow.
13830 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
13831 * eval.c (apply_lambda):
13832 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
13833 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
13834 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
13836 * callint.c (Fcall_interactively): Don't use index var as event count.
13838 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
13839 * mem-limits.h (SIZE): Remove; no longer used.
13841 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
13843 Remove unnecessary casts.
13844 * xterm.c (x_term_init):
13845 * xfns.c (x_set_border_pixel):
13846 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
13847 These aren't needed now that we assume ANSI C.
13849 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
13850 It's more likely to cause problems (due to unsigned overflow)
13853 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
13855 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
13857 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
13859 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
13861 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
13863 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
13865 GLYPH_CODE_FACE returns EMACS_INT, not int.
13866 * dispextern.h (merge_faces):
13867 * xfaces.c (merge_faces):
13868 * xdisp.c (get_next_display_element, next_element_from_display_vector):
13869 Don't assume EMACS_INT fits in int.
13871 * character.h (CHAR_VALID_P): Remove unused parameter.
13872 * fontset.c, lisp.h, xdisp.c: All uses changed.
13874 * editfns.c (Ftranslate_region_internal): Omit redundant test.
13876 * fns.c (concat): Minor tuning based on overflow analysis.
13877 This doesn't fix any bugs. Use int to hold character, instead
13878 of constantly refetching from Emacs object. Use XFASTINT, not
13879 XINT, for value known to be a character. Don't bother comparing
13880 a single byte to 0400, as it's always less.
13882 * floatfns.c (Fexpt):
13883 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
13885 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
13888 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
13890 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
13891 Without this fix, on a 64-bit host (aset S 0 4294967386) would
13892 incorrectly succeed when S was a string, because 4294967386 was
13893 truncated before it was used.
13895 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
13896 Otherwise, an out-of-range integer could cause undefined behavior
13899 * composite.c: Use int, not EMACS_INT, for characters.
13900 (fill_gstring_body, composition_compute_stop_pos): Use int, not
13901 EMACS_INT, for values that are known to be in character range.
13902 This doesn't fix any bugs but is the usual style inside Emacs and
13903 may generate better code on 32-bit machines.
13905 Make sure a 64-bit char is never passed to ENCODE_CHAR.
13906 This is for reasons similar to the recent CHAR_STRING fix.
13907 * charset.c (Fencode_char): Check that character arg is actually
13908 a character. Pass an int to ENCODE_CHAR.
13909 * charset.h (ENCODE_CHAR): Verify that the character argument is no
13910 wider than 'int', as a compile-time check to prevent future regressions
13913 * character.c (char_string): Remove unnecessary casts.
13915 Make sure a 64-bit char is never passed to CHAR_STRING.
13916 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
13917 by silently ignoring the top 32 bits, allowing some values
13918 that were far too large to be valid characters.
13919 * character.h: Include <verify.h>.
13920 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
13921 arguments are no wider than unsigned, as a compile-time check
13922 to prevent future regressions in this area.
13924 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
13925 (Fsubst_char_in_region):
13927 * xdisp.c (decode_mode_spec_coding):
13928 Adjust to CHAR_STRING's new requirement.
13929 * editfns.c (Finsert_char, Fsubst_char_in_region):
13930 * fns.c (concat): Check that character args are actually
13931 characters. Without this test, these functions did the wrong
13932 thing with wildly out-of-range values on 64-bit hosts.
13934 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
13935 These casts should not be needed on 32-bit hosts, either.
13936 * keyboard.c (read_char):
13937 * lread.c (Fload): Remove casts to unsigned.
13939 * lisp.h (UNSIGNED_CMP): New macro.
13940 This fixes comparison bugs on 64-bit hosts.
13941 (ASCII_CHAR_P): Use it.
13942 * casefiddle.c (casify_object):
13943 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
13944 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
13945 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
13946 * dispextern.h (FACE_FROM_ID):
13947 * keyboard.c (read_char): Use UNSIGNED_CMP.
13949 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
13950 not to EMACS_INT, to avoid GCC warning.
13952 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
13954 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
13955 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
13956 isn't needed on 32-bit machines.
13958 * buffer.c (Fgenerate_new_buffer_name):
13959 Use EMACS_INT for count, not int.
13960 (advance_to_char_boundary): Return EMACS_INT, not int.
13962 * data.c (Qcompiled_function): Now static.
13964 * window.c (window_body_lines): Now static.
13966 * image.c (gif_load): Rename local to avoid shadowing.
13968 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
13969 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
13970 * alloc.c (make_save_value): Integer argument is now of type
13971 ptrdiff_t, not int.
13972 (mark_object): Use ptrdiff_t, not int.
13973 * lisp.h (pD): New macro.
13974 * print.c (print_object): Use it.
13976 * alloc.c: Use EMACS_INT, not int, to count objects.
13977 (total_conses, total_markers, total_symbols, total_vector_size)
13978 (total_free_conses, total_free_markers, total_free_symbols)
13979 (total_free_floats, total_floats, total_free_intervals)
13980 (total_intervals, total_strings, total_free_strings):
13981 Now EMACS_INT, not int. All uses changed.
13982 (Fgarbage_collect): Compute overall total using a double, so that
13983 integer overflow is less likely to be a problem. Check for overflow
13984 when converting back to an integer.
13985 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
13986 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
13987 These were 'int' variables that could overflow on 64-bit hosts;
13988 they were never used, so remove them instead of repairing them.
13989 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
13990 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
13991 Previously, this ceilinged at INT_MAX, but that doesn't work on
13993 (allocate_pseudovector): Don't use EMACS_INT when int would do.
13995 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
13996 (allocate_vectorlike): Check for ptrdiff_t overflow.
13997 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
13998 when a (possibly-narrower) signed value would do just as well.
13999 We prefer using signed arithmetic, to avoid comparison confusion.
14001 * alloc.c: Catch some string size overflows that we were missing.
14002 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
14003 for convenience in STRING_BYTES_MAX.
14004 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
14005 The definition here is exact; the one in lisp.h was approximate.
14006 (allocate_string_data): Check for string overflow. This catches
14007 some instances we weren't catching before. Also, it catches
14008 size_t overflow on (unusual) hosts where SIZE_MAX <= min
14009 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
14010 and ptrdiff_t and EMACS_INT are both 64 bits.
14012 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
14013 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
14014 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
14016 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
14018 * alloc.c (Fmake_string): Check for out-of-range init.
14020 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
14022 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
14024 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
14026 * xfns.c (x_set_scroll_bar_default_width): Remove argument to

14029 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
14030 (int_gtk_range_get_value): Move to the scroll bar part of the file.
14031 (style_changed_cb): Call update_theme_scrollbar_width and call
14032 x_set_scroll_bar_default_width and xg_frame_set_char_size for
14033 all frames (Bug#8505).
14034 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
14035 Call gtk_window_set_resizable if HAVE_GTK3.

14037 and height if HAVE_GTK3 (Bug#8505).
14038 (scroll_bar_width_for_theme): New variable.
14039 (update_theme_scrollbar_width): New function.
14040 (xg_get_default_scrollbar_width): Move code to
14041 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
14042 (xg_initialize): Call update_theme_scrollbar_width.
14044 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
14046 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
14048 2011-06-12 Martin Rudalics <rudalics@gmx.at>
14050 * frame.c (make_frame): Call other_buffer_safely instead of
14053 * window.c (temp_output_buffer_show): Call display_buffer with
14054 second argument Vtemp_buffer_show_specifiers and reset latter
14055 immediately after the call.
14056 (Vtemp_buffer_show_specifiers): New variable.
14057 (auto_window_vscroll_p, next_screen_context_lines)
14058 (Vscroll_preserve_screen_position): Remove leading asterisks from

14241 Remove static from declaration of Qdelete_window, it's
14242 temporarily needed by Fbury_buffer.
14243 (replace_window): Don't assign orig_top_line and

14248 Replace Fdelete_window calls with calls to Qdelete_window.
14249 (Fdelete_other_windows): Remove. Deleting other windows is

14609 (display_prop_intangible_p): Reimplement to call
14610 handle_display_spec instead of single_display_spec_intangible_p.

14622 value of a `display' property is a "replacing spec".
14623 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
14624 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

14654 * gnutls.c: Use Emacs's memory allocators.
14655 Without this change, the gnutls library would invoke malloc etc.
14656 directly, which causes problems on non-SYNC_INPUT hosts, and which
14657 runs afoul of improving memory_full behavior. (Bug#8761)
14658 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
14659 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
14660 xfree instead of the default malloc, realloc, free.
14661 (Fgnutls_boot): No need to check for memory allocation failure,
14662 since xmalloc does that for us.
14664 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

14685 for hashes and hash indexes, instead of 'unsigned' and 'int'.
14686 * alloc.c (allocate_vectorlike):
14687 Check for overflow in vector size calculations.
14688 * ccl.c (ccl_driver):
14689 Check for overflow when converting EMACS_INT to int.

14691 need to be updated by these changes.
14692 * fns.c (make_hash_table, maybe_resize_hash_table):
14693 Check for integer overflow with large hash tables.
14694 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
14695 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
14696 (SXHASH_REDUCE): New macro.
14697 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
14698 Use it instead of discarding useful hash info with large hash values.
14699 (sxhash_float): New function.
14700 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
14701 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
14702 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
14703 Rewrite to use FIXNUM_BITS, as this simplifies things.
14704 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
14705 Adjust signatures to match updated version of code.
14706 (consing_since_gc): Now EMACS_INT, since a single hash table can
14707 use more than INT_MAX bytes.

14722 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
14723 Update dependencies.
14725 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14727 * data.c (init_data): Remove code for UTS, this system is not
14730 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14732 Don't force ./temacs to start in terminal mode.
14734 * frame.c (make_initial_frame): Initialize faces in all cases, not
14735 only when CANNOT_DUMP is defined.
14736 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
14738 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14740 * dispnew.c (add_window_display_history): Use const for the string
14741 pointer. Remove declaration, not needed.
14743 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
14745 Use 'inline', not 'INLINE'.
14746 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
14747 * alloc.c, fontset.c (INLINE): Remove.
14748 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
14749 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
14750 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
14751 * gmalloc.c (register_heapinfo): Use inline unconditionally.
14752 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
14754 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14756 Make it possible to run ./temacs.
14758 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
14759 syms_of_callproc does the same thing. Remove test for
14760 "initialized", do it in the caller.
14761 * emacs.c (main): Avoid calling set_initial_environment when dumping.
14763 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
14765 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
14766 (read_minibuf): Use get_minibuffer.
14767 (syms_of_minibuf): Use DEFSYM.
14768 (Qmetadata): New var.
14769 * data.c (Qbuffer): Don't make it static.
14770 (syms_of_data): Use DEFSYM.
14772 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
14774 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
14775 (CCL_CODE_MIN): New macro.
14777 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
14779 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
14781 * eval.c (Qdebug): Now static.
14782 * lisp.h (Qdebug): Remove decl. This reverts a part of the
14783 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
14784 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
14786 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14788 * image.c: Various fixes to ImageMagick code comments.
14789 (Fimagemagick_types): Doc fix.
14791 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
14793 Minor fixes prompted by GCC 4.6.0 warnings.
14795 * xselect.c (converted_selections, conversion_fail_tag): Now static.
14797 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
14798 (x_clipboard_manager_save_all): Move extern decl to ...
14799 * xterm.h: ... here, so that it can be checked for consistency.
14801 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14803 * xselect.c (x_clipboard_manager_save_frame)
14804 (x_clipboard_manager_save_all): New functions.
14805 (Fx_clipboard_manager_save): Lisp function deleted.
14807 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
14808 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
14810 * xterm.h: Update prototype.
14812 2011-05-28 William Xu <william.xwl@gmail.com>
14814 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
14815 exiting (Bug#8239).
14817 2011-05-28 Jim Meyering <meyering@redhat.com>
14819 Avoid a sign-extension bug in crypto_hash_function.
14820 * fns.c (to_uchar): Define.
14821 (crypto_hash_function): Use it to convert some newly-signed
14822 variables to unsigned, to avoid sign-extension bugs. For example,
14823 without this change, (md5 "truc") would evaluate to
14824 45723a2aff78ff4fff7fff1114760e62 rather than the expected
14825 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
14826 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
14828 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14830 Integer overflow fixes.
14832 * dbusbind.c: Serial number integer overflow fixes.
14833 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
14834 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
14835 to hold a serial number that is too large for a fixnum.
14836 (Fdbus_method_return_internal, Fdbus_method_error_internal):
14837 Check for serial numbers out of range. Decode any serial number
14838 that was so large that it became a float. (Bug#8722)
14840 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
14841 (Fdbus_call_method, Fdbus_call_method_asynchronously):
14842 Use XFASTINT rather than XUINT when numbers are nonnegative.
14843 (xd_append_arg, Fdbus_method_return_internal):
14844 (Fdbus_method_error_internal): Likewise. Also, for unsigned
14845 arguments, check that Lisp number is nonnegative, rather than
14846 silently wrapping negative numbers around. (Bug#8722)
14847 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
14850 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
14852 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
14854 ccl: Add integer overflow checks.
14855 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
14856 (IN_INT_RANGE): New macros.
14857 (ccl_driver): Use them to check for integer overflow when
14858 decoding a CCL program. Many of the new checks are whether XINT (x)
14859 fits in int; it doesn't always, on 64-bit hosts. The new version
14860 doesn't catch all possible integer overflows, but it's an
14861 improvement. (Bug#8719)
14863 * alloc.c (make_event_array): Use XINT, not XUINT.
14864 There's no need for unsigned here.
14866 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
14867 This follows up to the 2011-05-06 change that substituted uintptr_t
14868 for EMACS_INT. This case wasn't caught back then.
14870 Rework Fformat to avoid integer overflow issues.
14871 * editfns.c: Include <float.h> unconditionally, as it's everywhere
14872 now (part of C89). Include <verify.h>.
14873 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
14874 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
14875 (Fformat): Avoid the prepass trying to compute sizes; it was only
14876 approximate and thus did not catch overflow reliably. Instead, walk
14877 through the format just once, formatting and computing sizes as we go,
14878 checking for integer overflow at every step, and allocating a larger
14879 buffer as needed. Keep track separately whether the format is
14880 multibyte. Keep only the most-recently calculated precision, rather
14881 than them all. Record whether each argument has been converted to
14882 string. Use EMACS_INT, not int, for byte and char and arg counts.
14883 Support field widths and precisions larger than INT_MAX. Avoid
14884 sprintf's undefined behavior with conversion specifications such as %#d
14885 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
14886 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
14887 formatting out-of-range floating point numbers with int
14888 formats. (Bug#8668)
14890 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
14892 * data.c: Avoid integer truncation in expressions involving floats.
14893 * data.c: Include <intprops.h>.
14894 (arith_driver): When there's an integer overflow in an expression
14895 involving floating point, convert the integers to floating point
14896 so that the resulting value does not suffer from catastrophic
14897 integer truncation. For example, on a 64-bit host (* 4
14898 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
14899 Do not rely on undefined behavior after integer overflow.
14901 merge count_size_as_multibyte, parse_str_to_multibyte
14902 * character.c, character.h (count_size_as_multibyte):
14903 Rename from parse_str_to_multibyte; all uses changed.
14904 Check for integer overflow.
14905 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
14906 since it's now a duplicate of the other. This is more of
14907 a character than a buffer op, so better that it's in character.c.
14908 * fns.c, print.c: Adjust to above changes.
14910 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
14912 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
14914 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14916 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14917 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
14918 (x_clipboard_manager_save): Now static.
14919 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
14921 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14922 (crypto_hash_function): Now static.
14923 Fix pointer signedness problems. Avoid unnecessary initializations.
14925 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
14927 * termhooks.h (Vselection_alist): Make it terminal-local.
14929 * terminal.c (create_terminal): Initialize it.
14931 * xselect.c: Support for clipboard managers.
14932 (Vselection_alist): Move to termhooks.h as terminal-local var.
14933 (LOCAL_SELECTION): New macro.
14934 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
14935 (symbol_to_x_atom): Remove gratuitous arg.
14936 (x_handle_selection_request, lisp_data_to_selection_data)
14937 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
14938 (x_own_selection, x_get_local_selection, x_convert_selection):
14939 New arg, specifying work frame. Use terminal-local Vselection_alist.
14940 (some_frame_on_display): Delete unused function.
14941 (Fx_own_selection_internal, Fx_get_selection_internal)
14942 (Fx_disown_selection_internal, Fx_selection_owner_p)
14943 (Fx_selection_exists_p): New optional frame arg.
14944 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
14945 (x_handle_selection_clear): Don't treat other terminals with the
14946 same keyboard specially. Use the terminal-local Vselection_alist.
14947 (x_clear_frame_selections): Use Frun_hook_with_args.
14949 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
14951 * xterm.h: Add support for those atoms.
14953 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
14955 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
14956 (converted_selections, conversion_fail_tag): New global variables.
14957 (x_selection_request_lisp_error): Free the above.
14958 (x_get_local_selection): Remove unnecessary code.
14959 (x_reply_selection_request): Args changed; handle arbitrary array
14960 of converted selections stored in converted_selections.
14961 Separate the XChangeProperty and SelectionNotify steps.
14962 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
14963 (x_convert_selection): New function.
14964 (x_handle_selection_event): Simplify.
14965 (x_get_foreign_selection): Don't ignore incoming requests while
14966 waiting for an answer; this will fail when we implement
14967 SAVE_TARGETS, and seems unnecessary anyway.
14968 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
14969 (Vx_sent_selection_functions): Doc fix.
14971 2011-05-26 Leo Liu <sdl.web@gmail.com>
14973 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
14975 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14977 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
14979 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
14980 for fringe update if it has periodic bitmap.
14981 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
14982 and fringe_bitmap_periodic_p.
14984 * fringe.c (get_fringe_bitmap_data): New function.
14985 (draw_fringe_bitmap_1, update_window_fringes): Use it.
14986 (update_window_fringes): Record periodicity of fringe bitmap in glyph
14987 row. Mark glyph row for fringe update if periodicity changed.
14989 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
14990 for fringe update unless it has periodic bitmap.
14992 2011-05-25 Kenichi Handa <handa@m17n.org>
14994 * xdisp.c (get_next_display_element): Set correct it->face_id for
14995 a static composition.
14997 2011-05-24 Leo Liu <sdl.web@gmail.com>
15000 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
15002 * fns.c (crypto_hash_function, Fsha1): New function.
15003 (Fmd5): Use crypto_hash_function.
15004 (syms_of_fns): Add Ssha1.
15006 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
15008 * gnutls.c: Remove unused macros.
15009 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
15010 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
15011 Remove macros that are defined and never used.
15012 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
15014 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
15016 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
15017 (Fx_get_selection_internal): Minor cleanup.
15018 (Fx_own_selection_internal): Rename arguments for consistency with
15021 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
15023 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
15025 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
15027 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
15029 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15031 * dispnew.c (scrolling_window): Don't exclude the case that the
15032 last enabled row in the desired matrix touches the bottom boundary.
15034 2011-05-21 Glenn Morris <rgm@gnu.org>
15036 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
15037 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
15038 and add some more files.
15040 2011-05-20 Eli Zaretskii <eliz@gnu.org>
15042 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
15043 report_file_error introduced by the change from 2011-05-07.
15045 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
15047 * systime.h (Time): Define only if emacs is defined.
15048 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
15049 where the include path doesn't have X11/X.h by default. See
15050 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
15052 2011-05-20 Kenichi Handa <handa@m17n.org>
15054 * composite.c (find_automatic_composition): Fix previous change.
15056 2011-05-20 Glenn Morris <rgm@gnu.org>
15058 * lisp.mk: New file, split from Makefile.in.
15059 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
15060 (shortlisp): Remove.
15061 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
15063 2011-05-19 Glenn Morris <rgm@gnu.org>
15065 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
15066 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
15067 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
15068 (lisp): Set the order to that of loadup.el.
15069 (shortlisp): Make it a copy of $lisp.
15070 (SOME_MACHINE_LISP): Remove.
15071 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
15072 Use just $shortlisp, not $SOME_MACHINE_LISP too.
15074 2011-05-18 Kenichi Handa <handa@m17n.org>
15076 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
15077 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
15078 (find_automatic_composition): Mostly rewrite for efficiency.
15080 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
15082 * makefile.w32-in: Update dependencies.
15084 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
15086 * menu.c: Include limits.h (fixes the MS-Windows build broken by
15087 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
15089 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
15091 Fix some integer overflow issues, such as string length overflow.
15093 * insdel.c (count_size_as_multibyte): Check for string overflow.
15095 * character.c (lisp_string_width): Check for string overflow.
15096 Use EMACS_INT, not int, for string indexes and lengths; in
15097 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
15098 the resulting string length overflows an EMACS_INT; instead,
15099 report a string overflow if no precision given. When checking for
15100 precision exhaustion, use a check that cannot possibly have
15101 integer overflow. (Bug#8675)
15102 * character.h (lisp_string_width): Adjust to new signature.
15104 * alloc.c (string_overflow): New function.
15105 (Fmake_string): Use it. This doesn't change behavior, but saves
15106 a few bytes and will simplify future changes.
15107 * character.c (string_escape_byte8): Likewise.
15108 * lisp.h (string_overflow): New decl.
15110 Fixups, following up to the user-interface timestamp change.
15111 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
15112 for UI timestamps, instead of unsigned long.
15113 * msdos.c (mouse_get_pos): Likewise.
15114 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
15115 * w32gui.h (Time): Define by including "systime.h" rather than by
15116 declaring it ourselves. (Bug#8664)
15118 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
15119 * image.c (clear_image_cache): Likewise.
15121 * term.c (term_mouse_position): Don't assume time_t wraparound.
15123 Be more systematic about user-interface timestamps.
15124 Before, the code sometimes used 'Time', sometimes 'unsigned long',
15125 and sometimes 'EMACS_UINT', to represent these timestamps.
15126 This change causes it to use 'Time' uniformly, as that's what X uses.
15127 This makes the code easier to follow, and makes it easier to catch
15128 integer overflow bugs such as Bug#8664.
15129 * frame.c (Fmouse_position, Fmouse_pixel_position):
15130 Use Time, not unsigned long, for user-interface timestamps.
15131 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
15132 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
15133 * keyboard.h (last_event_timestamp): Likewise.
15134 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
15135 * menu.h (xmenu_show): Likewise.
15136 * term.c (term_mouse_position): Likewise.
15137 * termhooks.h (struct input_event.timestamp): Likewise.
15138 (struct terminal.mouse_position_hook): Likewise.
15139 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
15140 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
15141 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
15142 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
15143 what it was before.
15144 * menu.h, termhooks.h: Include "systime.h", for Time.
15146 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
15147 Don't assume that the difference between two unsigned long values
15148 can fit into an integer. At this point, we know button_down_time
15149 <= event->timestamp, so the difference must be nonnegative, so
15150 there's no need to cast the result if double-click-time is
15151 nonnegative, as it should be; check that it's nonnegative, just in
15152 case. This bug is triggered when events are more than 2**31 ms
15153 apart (about 25 days). (Bug#8664)
15155 * xselect.c (last_event_timestamp): Remove duplicate decl.
15156 (x_own_selection): Remove needless cast to unsigned long.
15158 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
15159 that always fit in int. Use a sentinel instead of a counter, to
15160 avoid a temp and to allay GCC's concerns about possible int overflow.
15161 * frame.h (struct frame): Use int for menu_bar_items_used
15162 instead of EMACS_INT, since it always fits in int.
15164 * menu.c (grow_menu_items): Check for int overflow.
15166 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
15168 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
15169 Before, the code was not consistent. These values cannot exceed
15170 2**31 - 1 so there's no need to make them unsigned.
15171 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
15172 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
15173 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
15175 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
15177 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
15178 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
15179 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
15180 presumably because the widths might not match.
15182 * window.c (size_window): Avoid needless test at loop start.
15184 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
15186 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
15188 2011-05-12 Drew Adams <drew.adams@oracle.com>
15190 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
15192 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15194 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
15195 `width' to `bar_area_x' and `bar_area_width', respectively.
15196 (x_scroll_run): Take account of fringe background extension.
15198 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
15199 Rename local vars `left' and `width' to `bar_area_x' and
15200 `bar_area_width', respectively.
15201 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
15202 background extension.
15204 2011-05-10 Jim Meyering <meyering@redhat.com>
15206 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
15208 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
15210 * image.c (Finit_image_library): Return t for built-in image types,
15211 like pbm and xbm. (Bug#8640)
15213 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
15215 * w32menu.c (set_frame_menubar): Fix submenu allocation.
15217 2011-05-07 Eli Zaretskii <eliz@gnu.org>
15219 * w32console.c (Fset_screen_color): Doc fix.
15220 (Fget_screen_color): New function.
15221 (syms_of_ntterm): Defsubr it.
15223 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
15224 unlink the temporary file if Fcall_process didn't create it in the
15226 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
15227 child process will be redirected to a file specified with `:file'.
15228 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
15229 cue to call_process_cleanup not to close that handle.
15231 2011-05-07 Ben Key <bkey76@gmail.com>
15233 * makefile.w32-in: The bootstrap-temacs rule now makes use of
15234 one of two shell specific rules, either bootstrap-temacs-CMD or
15235 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
15236 to the previous implementation of the bootstrap-temacs rule.
15237 The bootstrap-temacs-CMD rule is similar to the previous
15238 implementation of the bootstrap-temacs rule except that it
15239 makes use of the ESC_CFLAGS variable instead of the CFLAGS
15242 These changes, along with some changes to nt/configure.bat,
15243 nt/gmake.defs, and nt/nmake.defs, are required to extend my
15244 earlier fix to add support for --cflags and --ldflags options
15245 that include quotes so that it works whether make uses cmd or
15248 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
15250 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
15251 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
15253 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
15254 a string. Handle both cases.
15255 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
15256 (Fdbus_register_method): Use Qinvalid_function.
15258 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
15260 * makefile.w32-in: Update dependencies.
15261 (LISP_H): Add inttypes.h and stdin.h.
15262 (PROCESS_H): Add unistd.h.
15264 2011-05-06 Eli Zaretskii <eliz@gnu.org>
15266 * lread.c: Include limits.h (fixes the MS-Windows build broken by
15267 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
15269 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
15271 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
15273 * term.c (vfatal): Remove stray call to va_end.
15274 It's not needed and the C Standard doesn't allow it here anyway.
15276 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
15277 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
15279 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
15282 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
15284 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15286 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
15288 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
15290 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
15292 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
15293 * charset.c (Fdefine_charset_internal): Don't initialize
15294 charset.code_space[15]. The value was garbage, on hosts with
15295 32-bit int (Bug#8600).
15297 * lread.c (read_integer): Be more consistent with string-to-number.
15298 Use string_to_number to do the actual conversion; this avoids
15299 rounding errors and fixes some other screwups. Without this fix,
15300 for example, #x1fffffffffffffff was misread as -2305843009213693952.
15301 (digit_to_number): Move earlier, for benefit of read_integer.
15302 Return -1 if the digit is out of range for the base, -2 if it is
15303 not a digit in any supported base. (Bug#8602)
15305 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
15307 * dispnew.c (scrolling_window): Return 1 if we scrolled,
15308 to match comment at start of function. This also removes a
15309 GCC warning about overflow in a 32+64-bit port.
15311 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
15313 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
15314 Reported by Stefan Monnier in
15315 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
15316 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
15317 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
15319 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
15320 (EMACS_UINTPTR): Likewise, with uintptr_t.
15322 * lisp.h: Prefer 64-bit EMACS_INT if available.
15323 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
15324 on 32-bit hosts that have 64-bit int, so that they can access
15326 However, temporarily disable this change unless the temporary
15327 symbol WIDE_EMACS_INT is defined.
15329 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
15331 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
15332 This removes an assumption that EMACS_INT and long are the same
15333 width as pointers. The assumption is true for Emacs porting targets
15334 now, but we want to make other targets possible.
15335 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
15336 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
15337 In the rest of the code, change types of integers that hold casted
15338 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
15339 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
15340 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
15341 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
15342 No need to cast type when ORing.
15343 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
15344 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
15345 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
15346 assume EMACS_INT is the same width as char *.
15347 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
15348 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
15349 Remove no-longer-needed casts.
15350 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
15351 (xg_tool_bar_help_callback, xg_make_tool_item):
15352 Use EMACS_INTPTR to hold an integer
15353 that will be cast to void *; this can avoid a GCC warning
15354 if EMACS_INT is not the same width as void *.
15355 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
15356 * xdisp.c (display_echo_area_1, resize_mini_window_1):
15357 (current_message_1, set_message_1):
15358 Use a local to convert to proper width without a cast.
15359 * xmenu.c (dialog_selection_callback): Likewise.
15361 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
15362 Also, don't assume VALBITS / RAND_BITS is less than 5,
15363 and don't rely on undefined behavior when shifting a 1 left into
15365 * lisp.h (get_random): Change signature to match.
15367 * lread.c (hash_string): Use size_t, not int, for hash computation.
15368 Normally we prefer signed values; but hashing is special, because
15369 it's better to use unsigned division on hash table sizes so that
15370 the remainder is nonnegative. Also, size_t is the natural width
15371 for hashing into memory. The previous code used 'int', which doesn't
15372 retain enough info to hash well into very large tables.
15373 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
15375 * dbusbind.c: Don't possibly lose pointer info when converting.
15376 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
15377 Use XPNTR rather than XHASH, so that the high-order bits of
15378 the pointer aren't lost when converting through void *.
15380 * eval.c (Fautoload): Don't double-shift a pointer.
15382 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
15384 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
15386 * gnutls.c (DEF_GNUTLS_FN):
15387 * image.c (DEF_IMGLIB_FN): Make function pointers static.
15389 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
15391 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
15394 2011-05-05 Eli Zaretskii <eliz@gnu.org>
15396 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
15397 New version that can reserve upto 2GB of heap space.
15399 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
15401 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
15403 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
15405 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
15406 `gnutls_certificate_set_x509_key_file'.
15408 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
15410 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
15411 Update dependencies.
15413 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15415 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
15416 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
15417 Remove unused parameter `fildes'.
15418 * process.c (read_process_output, send_process): Don't pass it.
15420 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15422 Fix previous change: the library cache is defined in w32.c.
15423 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
15424 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
15426 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15428 Implement dynamic loading of GnuTLS on Windows.
15430 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
15431 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
15432 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
15435 * gnutls.c (Qgnutls_dll): Define.
15436 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
15437 (gnutls_*): Declare function pointers.
15438 (init_gnutls_functions): New function to initialize function pointers.
15439 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
15440 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
15441 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
15442 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
15443 (emacs_gnutls_write, emacs_gnutls_read)
15444 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
15445 (Fgnutls_available_p): New function.
15446 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
15447 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
15448 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
15450 * image.c: Include w32.h.
15451 (Vimage_type_cache): Delete.
15452 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
15453 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
15454 (w32_delayed_load): Move to w32.c.
15456 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
15458 * w32.c (QCloaded_from, Vlibrary_cache): Define.
15459 (w32_delayed_load): Move from image.c. When loading a library, record
15460 its filename in the :loaded-from property of the library id.
15461 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
15462 Initialize and staticpro them.
15463 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
15465 * process.c: Include lisp.h before w32.h, not after.
15466 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
15467 instead of gnutls_record_check_pending.
15469 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
15471 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
15473 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
15474 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
15477 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
15479 * xterm.c (x_set_frame_alpha): Do not set property on anything
15480 else than FRAME_X_OUTER_WINDOW (Bug#8608).

15495 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
15496 (Qgnutls_bootprop_callbacks_verify): Make static.
15498 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
15500 * callproc.c: Indentation fixup.
15502 * sysdep.c (wait_for_termination_1): Make static.
15503 (wait_for_termination, interruptible_wait_for_termination):
15504 Move after wait_for_termination_1.
15506 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
15508 * sysdep.c (interruptible_wait_for_termination): New function
15509 which is like wait_for_termination, but allows keyboard
15512 * callproc.c (Fcall_process): Add (:file "file") as an option for
15514 (Fcall_process_region): Ditto.
15516 2011-04-30 Eli Zaretskii <eliz@gnu.org>
15518 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
15519 rather than `XVECTOR (FOO)->size'.
15521 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
15522 inttypes.h, as a gnulib replacement is used if it not available in
15525 2011-04-21 Eli Zaretskii <eliz@gnu.org>
15527 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
15528 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
15529 of MOST_POSITIVE_FIXNUM. (Bug#8528)
15531 * coding.c (coding_alloc_by_realloc): Error out if destination
15532 will grow beyond MOST_POSITIVE_FIXNUM.
15533 (decode_coding_emacs_mule): Abort if there isn't enough place in

15544 %llo or %llx format is passed. (Bug#8545)
15546 * window.c (window_scroll_line_based): Use a marker instead of
15547 simple variables to record original value of point. (Bug#7952)
15549 * doprnt.c (doprnt): Fix the case where a multibyte sequence
15550 produced by %s or %c overflows available buffer space. (Bug#8545)
15552 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
15554 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
15555 (SIZE_MAX): Move defn after all includes, as they might #define it.
15557 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15559 * w32.c (init_environment): Warn about defaulting HOME to C:\.

15583 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
15585 * makefile.w32-in: Update dependencies.

15589 Improve `doprnt' and its usage. (Bug#8545)
15590 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
15591 `format_end'. Remove support for %l as a conversion specifier.
15592 Don't use xrealloc. Improve diagnostics when the %l size modifier
15593 is used. Update the commentary.
15595 * eval.c (verror): Simplify calculation of size_t.
15597 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
15600 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
15602 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
15605 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15607 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
15608 This makes this file independent of the recent pseudovector change.
15610 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
15612 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
15614 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
15615 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
15616 Remove unused local.
15617 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
15619 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
15620 GCC 4.6.0 optimizes based on type-based alias analysis.
15621 For example, if b is of type struct buffer * and v of type struct
15622 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
15623 != &v->size, and therefore "v->size = 1; b->size = 2; return
15624 v->size;" must therefore return 1. This assumption is incorrect
15625 for Emacs, since it type-puns struct Lisp_Vector * with many other
15626 types. To fix this problem, this patch adds a new type struct
15627 vectorlike_header that documents the constraints on layout of vectors
15628 and pseudovectors, and helps optimizing compilers not get fooled
15629 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
15630 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
15631 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
15633 (XSETPVECTYPE): Rewrite in terms of new macro.
15634 (XSETPVECTYPESIZE): New macro, specifying both type and size.
15635 This is a bit clearer, and further avoids the possibility of
15636 undesirable aliasing.
15637 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
15638 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
15639 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
15640 since Lisp_Subr is a special case (no "next" field).
15641 (ASIZE): Now uses header.size rather than size.
15642 All previous uses of XVECTOR (foo)->size replaced to use this macro,
15643 to avoid the hassle of writing XVECTOR (foo)->header.size.
15644 (struct vectorlike_header): New type.
15645 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
15646 object, to help avoid aliasing.
15647 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
15648 (SUBRP): Likewise, since Lisp_Subr is a special case.
15649 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
15650 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
15651 (struct Lisp_Hash_Table): Combine first two members into a single
15652 struct vectorlike_header member. All uses of "size" and "next" members
15653 changed to be "header.size" and "header.next".
15654 * buffer.h (struct buffer): Likewise.
15655 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
15656 * frame.h (struct frame): Likewise.
15657 * process.h (struct Lisp_Process): Likewise.
15658 * termhooks.h (struct terminal): Likewise.
15659 * window.c (struct save_window_data, struct saved_window): Likewise.
15660 * window.h (struct window): Likewise.
15661 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
15662 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
15663 * buffer.c (init_buffer_once): Likewise.
15664 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
15666 * process.c (Fformat_network_address): Use local var for size,
15669 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
15671 Make the Lisp reader and string-to-float more consistent (Bug#8525)
15672 * data.c (atof): Remove decl; no longer used or needed.
15673 (digit_to_number): Move to lread.c.
15674 (Fstring_to_number): Use new string_to_number function, to be
15675 consistent with how the Lisp reader treats infinities and NaNs.
15676 Do not assume that floating-point numbers represent EMACS_INT
15677 without losing information; this is not true on most 64-bit hosts.
15678 Avoid double-rounding errors, by insisting on integers when
15679 parsing non-base-10 numbers, as the documentation specifies.
15680 * lisp.h (string_to_number): New decl, replacing ...
15681 (isfloat_string): Remove.
15682 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
15683 (read1): Do not accept +. and -. as integers; this
15684 appears to have been a coding error. Similarly, do not accept
15685 strings like +-1e0 as floating point numbers. Do not report
15686 overflow for integer overflows unless the base is not 10 which
15687 means we have no simple and reliable way to continue.
15688 Break out the floating-point parsing into a new
15689 function string_to_number, so that Fstring_to_number parses
15690 floating point numbers consistently with the Lisp reader.
15691 (digit_to_number): Move here from data.c. Make it static inline.
15692 (E_CHAR, EXP_INT): Remove, replacing with ...
15693 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
15694 (string_to_number): New function, replacing isfloat_string.
15695 This function checks for valid syntax and produces the resulting
15696 Lisp float number too. Rework it so that string-to-number
15697 no longer mishandles examples like "1.0e+". Use strtoumax,
15698 so that overflow for non-base-10 numbers is reported only when
15699 there's no portable and simple way to convert to floating point.
15701 * textprop.c (set_text_properties_1): Rewrite for clarity,
15702 and to avoid GCC warning about integer overflow.
15704 * intervals.h (struct interval): Use EMACS_INT for members
15705 where EMACS_UINT might cause problems. See
15706 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
15707 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
15708 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
15710 (offset_intervals): Tell GCC not to worry about length overflow
15711 when negating a negative length.
15713 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
15714 (overrun_check_free): Likewise.
15716 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
15717 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
15720 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15721 (gnutls_make_error): Rename local to avoid shadowing.
15722 (gnutls_emacs_global_deinit): ifdef out; not used.
15723 (Fgnutls_boot): Use const for pointer to readonly storage.
15724 Comment out unused local. Fix pointer signedness problems.
15726 * lread.c (openp): Don't stuff size_t into an 'int'.
15727 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
15728 about possible signed overflow.
15730 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15731 (GDK_KEY_g): Don't define if already defined.
15732 (xg_prepare_tooltip): Avoid pointer signedness problem.
15733 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
15735 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
15736 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
15738 * xfns.c (Fx_window_property): Simplify a bit,
15739 to make a bit faster and to avoid GCC 4.6.0 warning.
15740 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
15742 * fns.c (internal_equal): Don't assume size_t fits in int.
15744 * alloc.c (compact_small_strings): Tighten assertion a little.
15746 Replace pEd with more-general pI, and fix some printf arg casts.
15747 * lisp.h (pI): New macro, generalizing old pEd macro to other
15748 conversion specifiers. For example, use "...%"pI"d..." rather
15749 than "...%"pEd"...".
15750 (pEd): Remove. All uses replaced with similar uses of pI.
15751 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
15752 * alloc.c (check_pure_size): Don't overflow by converting size to int.
15753 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
15754 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
15755 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
15756 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
15757 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
15759 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
15760 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
15761 * print.c (safe_debug_print, print_object): Likewise.
15762 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
15764 Use pI instead of if-then-else-abort. Use %p to avoid casts,
15765 avoiding the 0 flag, which is not portable.
15766 * process.c (Fmake_network_process): Use pI to avoid cast.
15767 * region-cache.c (pp_cache): Likewise.
15768 * xdisp.c (decode_mode_spec): Likewise.
15769 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
15770 behavior on 64-bit hosts with printf arg.
15771 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
15772 (x_stop_queuing_selection_requests): Likewise.
15773 (x_get_window_property): Don't truncate byte count to an 'int'
15776 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
15777 here, since it parses constructs like leading '-' and spaces,
15778 which are not wanted; and it overflows with large numbers.
15779 Instead, simply match F[0-9]+, which is what is wanted anyway.
15781 * alloc.c: Remove unportable assumptions about struct layout.
15782 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
15783 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
15784 (allocate_vectorlike, make_pure_vector): Use the new macros,
15785 plus offsetof, to remove unportable assumptions about struct layout.
15786 These assumptions hold on all porting targets that I know of, but
15787 they are not guaranteed, they're easy to remove, and removing them
15788 makes further changes easier.
15790 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
15791 This doesn't fix a bug but makes the code clearer.
15792 (string_overrun_cookie): Now const. Use initializers that
15793 don't formally overflow signed char, to avoid warnings.
15794 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
15795 can cause Emacs to crash when string overrun checking is enabled.
15796 (allocate_buffer): Don't assume sizeof (struct buffer) is a
15797 multiple of sizeof (EMACS_INT); it need not be, if
15798 alignof(EMACS_INT) < sizeof (EMACS_INT).
15799 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
15801 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

15808 supposed to be handshaking. (Bug#8556)
15809 Reported by Paul Eggert <eggert@cs.ucla.edu>.
15811 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

15821 * alloc.c (check_sblock, check_string_bytes)
15822 (check_string_free_list): Convert to standard C.
15824 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>

15828 2011-04-25 Eli Zaretskii <eliz@gnu.org>
15830 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
15831 "cast to pointer from integer of different size".
15833 Improve doprnt and its use in verror. (Bug#8545)
15834 * doprnt.c (doprnt): Document the set of format control sequences
15835 supported by the function. Use SAFE_ALLOCA instead of always
15838 * eval.c (verror): Don't limit the buffer size at size_max-1, that
15839 is one byte too soon. Don't use xrealloc; instead xfree and
15842 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
15844 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
15847 * gnutls.c: Renamed global_initialized to
15848 gnutls_global_initialized. Added internals for the
15849 :verify-hostname-error, :verify-error, and :verify-flags
15850 parameters of `gnutls-boot' and documented those parameters in the
15851 docstring. Start callback support.
15852 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
15853 unless a fatal error occurred. Call gnutls_alert_send_appropriate
15854 on error. Return error code.
15855 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
15856 (emacs_gnutls_read): Likewise.
15857 (Fgnutls_boot): Return handshake error code.
15858 (emacs_gnutls_handle_error): New function.
15859 (wsaerror_to_errno): Likewise.

15914 changes in globals.h immediately force recompilation.
15915 (TAGS): Depend on $(CURDIR)/m/intel386.h and
15916 $(CURDIR)/s/ms-w32.h.

15921 <char-direction-table>: Deleted.
15923 2011-04-23 Eli Zaretskii <eliz@gnu.org>
15925 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
15926 * doprnt.c: Include limits.h.
15927 (SIZE_MAX): New macro.
15928 (doprnt): Return a size_t value. 2nd arg is now size_t.
15929 Many local variables are now size_t instead of int or unsigned.
15930 Improve overflow protection. Support `l' modifier for integer
15931 conversions. Support %l conversion. Don't assume an EMACS_INT
15932 argument for integer conversions and for %c.
15934 * lisp.h (doprnt): Restore prototype.
15936 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
15937 $(SRC)/character.h.
15939 * Makefile.in (base_obj): Add back doprnt.o.
15941 * deps.mk (doprnt.o): Add back prerequisites.
15942 (callint.o): Depend on character.h.
15944 * eval.c (internal_lisp_condition_case): Include the handler
15945 representation in the error message.
15946 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
15947 when breaking from the loop.
15949 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
15951 * callint.c (Fcall_interactively): When displaying error message
15952 about invalid control letter, pass the character's codepoint, not
15953 a pointer to its multibyte form. Improve display of the character
15954 in octal and display also its hex code.
15956 * character.c (char_string): Use %x to display the (unsigned)
15957 codepoint of an invalid character, to avoid displaying a bogus
15960 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
15961 `error', not SYMBOL_NAME itself.
15963 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
15964 character arguments to `error'.
15966 * charset.c (check_iso_charset_parameter): Fix incorrect argument
15967 to `error' in error message about FINAL_CHAR argument. Make sure
15968 FINAL_CHAR is a character, and use %c when it is passed as
15969 argument to `error'.

16033 Define only if needed.
16035 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
16036 by pacifying GCC about it. Maybe it's time to retire it?

16512 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
16513 * lisp.h: Remove these decls.
16515 * buffer.c (buffer_count): Remove unused var.
16517 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
16518 so that it's not optimized away.
16519 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
16520 * dispextern.h (bidi_dump_cached_states): Remove, since it's
16521 exported only to the debugger.
16523 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
16524 * atimer.h (run_all_atimers): Remove; not exported.
16526 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
16527 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
16528 was inaccessible from Lisp.
16529 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
16530 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
16532 alloc.c: Import and export fewer symbols, and remove unused items.
16533 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
16535 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
16536 it's not optimized away by whole-program optimization.
16537 (message_enable_multibyte, free_misc): Remove.
16538 (catchlist, handlerlist, mark_backtrace):
16539 Declare only if BYTE_MARK_STACK.
16540 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
16541 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
16542 (message_enable_multibyte): Remove decl.

16548 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
16549 (mark_backtrace): Define only if BYTE_MARK_STACK.
16550 * xdisp.c (message_enable_multibyte): Now static.
16552 Declare Lisp_Object Q* variables to be 'static' if not exported.
16553 This makes it easier for human readers (and static analyzers)
16554 to see whether these variables are used from other modules.
16555 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
16556 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
16557 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

16561 * xmenu.c, xselect.c:
16562 Declare Q* vars static if they are not used in other modules.

16564 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
16565 Remove decls of unexported vars.
16566 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
16568 * lisp.h (DEFINE_FUNC): Make sname 'static'.
16570 Make Emacs functions such as Fatom 'static' by default.
16571 This makes it easier for human readers (and static analyzers)
16572 to see whether these functions can be called from other modules.
16573 DEFUN now defines a static function. To make the function external
16574 so that it can be used in other C modules, use the new macro DEFUE.
16575 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
16576 (Finit_image_library):
16577 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
16578 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
16579 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
16580 Remove decls, since these functions are now static.
16581 (Funintern, Fget_internal_run_time): New decls, since these functions
16582 were already external.
16584 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
16585 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

16591 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
16592 Mark functions with DEFUE instead of DEFUN,
16593 if they are used in other modules.
16594 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
16595 decls for now-static functions.
16596 * buffer.h (Fdelete_overlay): Remove decl.
16597 * callproc.c (Fgetenv_internal): Mark as internal.

16606 * image.c (Finit_image_library): New forward static decl.
16607 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
16608 * intervals.h (Fprevious_property_change):
16609 (Fremove_list_of_text_properties): Remove decls.
16610 * keyboard.c (Fthis_command_keys): Remove decl.
16611 (Fcommand_execute): New forward static decl.

16632 2011-04-13 Eli Zaretskii <eliz@gnu.org>
16634 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
16635 when at ZV. (Bug#8487)
16637 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
16639 * charset.c (Fclear_charset_maps): Use xfree instead of free.

16642 * sound.c (sound_cleanup, alsa_close): Likewise.
16643 * termcap.c (tgetent): Likewise.

16645 * xsettings.c (read_and_apply_settings): Likewise.
16647 * alloc.c (overrun_check_malloc, overrun_check_realloc)
16648 (overrun_check_free): Protoize.
16650 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
16652 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
16653 since callers should never pass a negative size.
16654 Change the signature to match that of plain 'read' and 'write'; see
16655 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
16656 * lisp.h: Update prototypes of emacs_write and emacs_read.
16658 2011-04-11 Eli Zaretskii <eliz@gnu.org>
16660 * xdisp.c (redisplay_window): Don't try to determine the character
16661 position of the scroll margin if the window start point w->startp
16662 is outside the buffer's accessible region. (Bug#8468)
16664 2011-04-10 Eli Zaretskii <eliz@gnu.org>
16666 Fix write-region and its subroutines for buffers > 2GB.
16667 * fileio.c (a_write, e_write): Modify declaration of arguments and
16668 local variables to support buffers larger than 2GB.
16669 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
16671 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
16672 argument, local variables, and return value.
16674 * lisp.h: Update prototypes of emacs_write and emacs_read.
16676 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
16678 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
16680 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
16682 Fix more problems found by GCC 4.6.0's static checks.
16684 * xdisp.c (vmessage): Use a better test for character truncation.
16686 * charset.c (load_charset_map): <, not <=, for optimization,
16687 and to avoid potential problems with integer overflow.
16688 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
16689 * casetab.c (set_identity, shuffle): Likewise.
16690 * editfns.c (Fformat): Likewise.
16691 * syntax.c (skip_chars): Likewise.
16693 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
16694 This also lets GCC 4.6.0 generate slightly better loop code.
16696 * callint.c (Fcall_interactively): <, not <=, for optimization.
16697 (Fcall_interactively): Count the number of arguments produced,
16698 not the number of arguments given. This is simpler and lets GCC
16699 4.6.0 generate slightly better code.
16701 * ftfont.c: Distingish more carefully between FcChar8 and char.
16702 The previous code passed unsigned char * to a functions like
16703 strlen and xstrcasecmp that expect char *, which does not
16704 conform to the C standard.
16705 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
16706 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
16707 char * when the C standard requires it.
16709 * keyboard.c (read_char): Remove unused var.
16711 * eval.c: Port to Windows vsnprintf (Bug#8435).
16712 Include <limits.h>.
16713 (SIZE_MAX): Define if the headers do not.
16714 (verror): Do not give up if vsnprintf returns a negative count.
16715 Instead, grow the buffer. This ports to Windows vsnprintf, which
16716 does not conform to C99. Problem reported by Eli Zaretskii.
16717 Also, simplify the allocation scheme, by avoiding the need for
16718 calling realloc, and removing the ALLOCATED variable.
16720 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
16722 Remove invocations of doprnt, as Emacs now uses vsnprintf.
16723 But keep the doprint source code for now, as we might revamp it
16724 and use it again (Bug#8435).
16725 * lisp.h (doprnt): Remove.
16726 * Makefile.in (base_obj): Remove doprnt.o.
16727 * deps.mk (doprnt.o): Remove.
16729 error: Print 32- and 64-bit integers portably (Bug#8435).
16730 Without this change, on typical 64-bit hosts error ("...%d...", N)
16731 was used to print both 32- and 64-bit integers N, which relied on
16732 undefined behavior.
16733 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
16734 * lisp.h (error, verror): Mark as printf-like functions.
16735 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
16736 Report overflow in size calculations when allocating printf buffer.
16737 Do not truncate output string at its first null byte.
16738 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
16739 Truncate the output at a character boundary, since vsnprintf does not
16741 * charset.c (check_iso_charset_parameter): Convert internal
16742 character to string before calling 'error', since %c now has the
16744 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
16745 overflow when computing char to be passed to 'error'. Do not
16746 pass Lisp_Object to 'error'; pass the integer instead.
16747 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
16748 formatted with plain %d.
16750 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
16752 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
16754 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
16756 * xterm.c (x_catch_errors): Remove duplicate declaration.
16758 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
16760 * xdisp.c, lisp.h (message_nolog): Remove; unused.
16762 2011-04-10 Jim Meyering <meyering@redhat.com>
16764 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
16765 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
16766 return ssize_t not "int", and use size_t as the buffer length.
16767 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
16768 * gnutls.h: Update declarations.
16769 * process.c (read_process_output): Use ssize_t, to match.
16770 (send_process): Likewise.
16772 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16774 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
16776 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16778 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
16779 Use unsigned char, to match FcChar8 type definition.
16781 * xterm.c (handle_one_xevent):
16782 * xmenu.c (create_and_show_popup_menu):
16783 * xselect.c (x_decline_selection_request)
16784 (x_reply_selection_request): Avoid type-punned deref of X events.
16786 2011-04-09 Eli Zaretskii <eliz@gnu.org>
16788 Fix some uses of `int' instead of EMACS_INT.
16789 * search.c (string_match_1, fast_string_match)
16790 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
16791 (scan_buffer, find_next_newline_no_quit)
16792 (find_before_next_newline, search_command, Freplace_match)
16793 (Fmatch_data): Make some `int' variables be EMACS_INT.
16795 * xdisp.c (display_count_lines): 3rd argument and return value now
16796 EMACS_INT. All callers changed.
16797 (pint2hrstr): Last argument is now EMACS_INT.
16799 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
16800 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
16801 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

16804 (decode_coding_ccl, decode_coding_charset)
16805 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
16806 (decode_coding_iso_2022, decode_coding_emacs_mule)
16807 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
16808 <char_offset, last_offset>: Declare EMACS_INT.

16810 (encode_coding_emacs_mule, encode_invocation_designation)
16811 (encode_designation_at_bol, encode_coding_iso_2022)
16812 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
16813 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
16815 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
16816 (encode_invocation_designation): Last argument P_NCHARS is now
16818 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
16819 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
16821 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
16824 * ccl.c (Fccl_execute_on_string): Declare some variables
16827 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
16829 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
16831 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
16833 * process.c (Fformat_network_address): Doc fix.
16835 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
16837 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
16839 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
16841 * keyboard.c (read_char): Call Lisp function help-form-show,
16842 instead of using internal_with_output_to_temp_buffer.
16843 (Qhelp_form_show): New var.
16844 (syms_of_keyboard): Use DEFSYM macro.
16846 * print.c (internal_with_output_to_temp_buffer): Function deleted.

16850 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
16852 * process.c (Flist_processes): Remove to Lisp.
16853 (list_processes_1): Delete.
16855 2011-04-06 Eli Zaretskii <eliz@gnu.org>
16857 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
16859 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
16861 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
16863 Fix more problems found by GCC 4.6.0's static checks.
16865 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
16867 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
16869 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
16871 * xdisp.c (vmessage): Mark as a printf-like function.
16873 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
16875 * sound.c (sound_warning): Don't crash if arg contains a printf format.
16877 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
16878 printf-like functions.
16879 (tiff_load): Add casts to remove these marks before passing them
16880 to system-supplied API.
16882 * eval.c (Fsignal): Remove excess argument to 'fatal'.
16884 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
16885 This avoids several warnings with gcc -Wstrict-overflow.
16886 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
16887 directly, rather than having caller test rule sign. This avoids
16888 some unnecessary tests.
16889 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
16890 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
16891 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
16893 * xfont.c (xfont_text_extents): Remove var that was set but not used.
16894 (xfont_open): Avoid unnecessary tests.
16896 * composite.c (composition_gstring_put_cache): Use unsigned integer.

16905 by using the new macro.
16907 * textprop.c (set_text_properties_1): Change while to do-while,
16908 since the condition is always true at first.
16910 * intervals.c (graft_intervals_into_buffer): Mark var as used.
16911 (interval_deletion_adjustment): Return unsigned value.
16914 * process.c (list_processes_1, create_pty, read_process_output):

16930 * print.c (print_error_message): Avoid int overflow.
16932 * font.c (font_list_entities): Redo for clarity,
16933 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.

16948 (wordify): Omit three unnecessary tests.
16950 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
16951 All callers changed. This avoids the need for an unused var.
16953 * casefiddle.c (casify_region): Remove var that is set but not used.
16955 * dired.c (file_name_completion): Remove var that is set but not used.
16957 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
16959 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
16960 (Finsert_file_contents): Remove unnecessary code checking fd.
16962 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
16963 Check for integer overflow on size calculations.
16965 * buffer.c (Fprevious_overlay_change): Remove var that is set
16968 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
16969 Remove vars that are set but not used.
16970 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
16971 (timer_check_2): Mark vars as initialized.
16973 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
16975 * image.c (lookup_image): Remove var that is set but not used.
16976 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
16978 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
16979 that are set but not used.
16981 * xfns.c (make_invisible_cursor): Don't return garbage
16982 if XCreateBitmapFromData fails (Bug#8410).
16984 * xselect.c (x_get_local_selection, x_handle_property_notify):
16985 Remove vars that are set but not used.
16987 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
16988 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
16990 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
16991 Remove var that is set but not used.
16992 (scroll_bar_windows_size): Now size_t, not int.
16993 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
16994 Check for overflow.
16996 * xfaces.c (realize_named_face): Remove vars that are set but not used.
16997 (map_tty_color) [!defined MSDOS]: Likewise.
16999 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
17001 * coding.c: Remove vars that are set but not used.
17002 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
17003 All callers changed.
17004 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
17005 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
17006 (decode_coding_charset): Remove vars that are set but not used.
17008 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
17009 that is set but not used.
17011 * print.c (print_object): Remove var that is set but not used.
17013 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
17014 The gnulib version avoids calling malloc in the usual case,
17015 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
17016 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
17017 * filelock.c (current_lock_owner): Likewise.
17018 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
17019 * sysdep.c: Include allocator.h, careadlinkat.h.
17020 (emacs_no_realloc_allocator): New static constant.
17021 (emacs_readlink): New function.
17022 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
17023 ../lib/careadlinkat.h.
17025 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
17027 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
17028 first non-nil return value).

17042 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
17043 and thereabouts. All callers changed.
17044 (get_per_char_metric): Remove parameter `f', unused since
17045 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
17047 2011-04-02 Jim Meyering <meyering@redhat.com>
17049 do not dereference NULL upon failed strdup
17050 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
17051 (ns_get_family): Likewise.
17053 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
17055 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
17057 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
17059 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
17062 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
17064 Add lexical binding.
17066 * window.c (Ftemp_output_buffer_show): New fun.
17067 (Fsave_window_excursion):
17068 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
17070 * lread.c (lisp_file_lexically_bound_p): New function.
17071 (Fload): Bind Qlexical_binding.
17072 (readevalloop): Remove `evalfun' arg.
17073 Bind Qinternal_interpreter_environment.
17074 (Feval_buffer): Bind Qlexical_binding.
17075 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
17077 (syms_of_lread): Declare `lexical-binding'.
17079 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
17081 * keyboard.c (eval_dyn): New fun.
17082 (menu_item_eval_property): Use it.
17084 * image.c (parse_image_spec): Use Ffunctionp.
17086 * fns.c (concat, mapcar1): Accept byte-code-functions.
17088 * eval.c (Fsetq): Handle lexical vars.
17089 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
17090 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
17091 (FletX, Flet): Obey lexical binding.
17092 (Fcommandp): Handle closures.
17093 (Feval): New `lexical' arg.
17094 (eval_sub): New function extracted from Feval. Use it almost
17095 everywhere where Feval was used. Look up vars in lexical env.
17097 (Ffunctionp): Move from subr.el.
17098 (Ffuncall): Handle closures.
17099 (apply_lambda): Remove `eval_flags'.
17100 (funcall_lambda): Handle closures and new byte-code-functions.
17101 (Fspecial_variable_p): New function.
17102 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
17103 but without exporting it to Lisp.
17105 * doc.c (Fdocumentation, store_function_docstring):
17106 * data.c (Finteractive_form): Handle closures.
17108 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
17111 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
17113 (exec_byte_code): New function extracted from Fbyte_code to handle new
17114 calling convention for byte-code-functions. Add new byte-codes.
17116 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
17118 * alloc.c (Fmake_symbol): Init new `declared_special' field.
17120 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
17122 * xdisp.c (redisplay_internal): Fix prototype.
17124 2011-03-31 Eli Zaretskii <eliz@gnu.org>
17126 * xdisp.c (SCROLL_LIMIT): New macro.
17127 (try_scrolling): Use it when setting scroll_limit.
17128 Limit scrolling to 100 screen lines.
17129 (redisplay_window): Even when falling back on "recentering",
17130 position point in the window according to scroll-conservatively,
17131 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
17133 (try_scrolling): When point is above the window, allow searching
17134 as far as scroll_max, or one screenful, to compute vertical
17135 distance from PT to the scroll margin position. This prevents
17136 try_scrolling from unnecessarily failing when
17137 scroll-conservatively is set to a value slightly larger than the
17138 window height. Clean up the case of PT below the margin at bottom
17139 of window: scroll_max can no longer be INT_MAX. When aggressive
17140 scrolling is in use, don't let point enter the opposite scroll
17141 margin as result of the scroll.
17142 (syms_of_xdisp) <scroll-conservatively>: Document the
17143 threshold of 100 lines for never-recentering scrolling.
17145 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
17147 * dispextern.h (move_it_by_lines):
17148 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

17150 (message_log_check_duplicate): Remove parameters `prev_bol' and
17151 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
17152 (redisplay_internal): Remove parameter `preserve_echo_area',
17153 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
17155 * indent.c (Fvertical_motion):
17156 * window.c (window_scroll_pixel_based, Frecenter):
17157 Don't pass `need_y_p' to `move_it_by_lines'.
17159 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
17161 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
17162 steal a few bits to be more compact.
17163 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
17164 Remove unneeded casts.
17166 * bytecode.c (Fbyte_code): CAR and CDR can GC.
17168 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
17170 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
17171 binding" message (bug#7967).
17173 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
17175 Fix more problems found by GCC 4.6.0's static checks.
17177 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
17178 Remove unused local var.
17180 * editfns.c (Fmessage_box): Remove unused local var.
17182 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
17183 (note_mode_line_or_margin_highlight, note_mouse_highlight):
17184 Omit unused local vars.
17185 * window.c (shrink_windows): Omit unused local var.
17186 * menu.c (digest_single_submenu): Omit unused local var.
17187 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
17188 Omit unused local var.
17190 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
17191 Don't assume string length fits in int.
17192 (keyremap_step, read_key_sequence): Use size_t for sizes.
17193 (read_key_sequence): Don't check last_real_key_start redundantly.
17195 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
17196 instead of alloca (Bug#8344).
17198 * eval.c (Fbacktrace): Don't assume nargs fits in int.
17199 (Fbacktrace_frame): Don't assume nframes fits in int.
17201 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
17203 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
17206 * term.c (produce_glyphless_glyph): Remove unnecessary test.
17208 * cm.c (calccost): Turn while-do into do-while, for clarity.
17210 * keyboard.c (syms_of_keyboard): Use the same style as later
17211 in this function when indexing through an array. This also
17212 works around GCC bug 48267.
17214 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
17216 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
17218 * chartab.c (sub_char_table_ref_and_range): Redo for slight
17219 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
17221 * keyboard.c, keyboard.h (num_input_events): Now size_t.
17222 This avoids undefined behavior on integer overflow, and is a bit
17223 more convenient anyway since it is compared to a size_t variable.
17225 Variadic C functions now count arguments with size_t, not int.
17226 This avoids an unnecessary limitation on 64-bit machines, which
17227 caused (substring ...) to crash on large vectors (Bug#8344).

17237 * fns.c (concat): Likewise.
17238 * frame.c (x_set_frame_parameters): Likewise.
17239 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
17240 0 if not found, not -1. All callers changed.
17242 * alloc.c (garbage_collect): Don't assume stack size fits in int.
17243 (stack_copy_size): Now size_t, not int.
17244 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
17246 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
17248 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
17249 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
17250 All callers changed.
17252 * lisp.h (multibyte_char_to_unibyte):
17253 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
17254 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

17265 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
17266 don't set the hook to nil, but remove the offending function instead.
17267 (Qcommand_hook_internal): Remove, unused.
17268 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
17269 Vcommand_hook_internal.
17271 * eval.c (enum run_hooks_condition): Remove.
17272 (funcall_nil, funcall_not): New functions.
17273 (run_hook_with_args): Call each function through a `funcall' argument.

17287 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
17288 All callers changed.
17290 * w32.c (_wsa_errlist): Use braces for struct initializers.
17292 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

17437 2011-03-23 Julien Danjou <julien@danjou.info>
17439 * term.c (Fsuspend_tty, Fresume_tty):
17440 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
17441 * window.c (temp_output_buffer_show):
17442 * insdel.c (signal_before_change):
17443 * frame.c (Fhandle_switch_frame):

17448 * callint.c (Fcall_interactively):
17449 * buffer.c (Fkill_all_local_variables):
17450 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
17452 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
17453 unconditionally since it does the check itself.
17455 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
17457 Fix more problems found by GCC 4.5.2's static checks.
17459 * coding.c (encode_coding_raw_text): Avoid unnecessary test
17460 the first time through the loop, since we know p0 < p1 then.
17461 This also avoids a gcc -Wstrict-overflow warning.
17463 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
17464 leading to a memory leak, possible in functions like
17465 load_charset_map_from_file that can allocate an unbounded number
17466 of objects (Bug#8318).
17468 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
17469 that could (at least in theory) be that large.
17471 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
17472 This is less likely to overflow, and avoids undefined behavior if
17473 overflow does occur. All callers changed. Use strtoul to scan
17474 for the unsigned long integer.
17475 (pint2hrstr): Simplify and tune code slightly.
17476 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

17486 * fileio.c (Fcopy_file): Report error if fchown or fchmod
17489 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
17491 * process.c (Fmake_network_process): Use socklen_t, not int,
17492 where POSIX says socklen_t is required in portable programs.
17493 This fixes a porting bug on hosts like 64-bit HP-UX, where
17494 socklen_t is wider than int (Bug#8277).
17495 (Fmake_network_process, server_accept_connection):
17496 (wait_reading_process_output, read_process_output):
17499 * process.c: Rename or move locals to avoid shadowing.

17509 Make tparam.h and terminfo.c consistent.
17510 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
17511 Include tparam.h instead, since it declares them.
17512 * cm.h (PC): Remove extern decl; tparam.h now does this.
17513 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
17514 * terminfo.c: Include tparam.h, to check interfaces.
17515 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
17516 (tparam): Adjust signature to match interface in tparam.h;
17517 this removes some undefined behavior. Check that outstring and len
17518 are zero, which they always are with Emacs.
17519 * tparam.h (PC, BC, UP): New extern decls.
17521 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
17522 (xftfont_open): Rename locals to avoid shadowing.

17539 (find_automatic_composition, composition_adjust_point): Likewise.
17540 (composition_update_it): Mark var as initialized.
17541 (find_automatic_composition): Mark vars as initialized,
17542 with a FIXME (Bug#8290).

17546 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
17547 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
17548 (BUF_DEC_POS): Be more systematic about renaming local temporaries
17549 to avoid shadowing.
17551 * textprop.c (property_change_between_p): Remove; unused.
17553 * intervals.c (interval_start_pos): Now static.
17555 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

17561 Fix pointer signedness.
17562 (alsa_choose_format): Remove unused local var.
17563 (wav_play): Initialize a variable to 0, to prevent undefined
17564 behavior (Bug#8278).
17566 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
17568 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
17570 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
17571 clobbering (Bug#8298).
17572 * sysdep.c (sys_subshell): Likewise.
17573 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
17575 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
17576 This should get cleaned up, so that child_setup has the
17577 same signature on all platforms.
17579 * callproc.c (call_process_cleanup): Now static.
17580 (relocate_fd): Rename locals to avoid shadowing.
17582 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
17584 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
17585 not to be necessary, and produces flickering.
17587 2011-03-20 Glenn Morris <rgm@gnu.org>
17589 * config.in: Remove file.
17591 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
17593 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
17594 are now in src/globals.h.
17595 (syms_of_minibuf): Remove spurious & from previous change.

17621 (sigchld_handler): Now static.
17623 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
17624 That way, the code declares only the vars that it needs.

17635 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
17636 Define only if needed.
17638 * unexelf.c (unexec): Name an expression,
17639 to avoid gcc -Wbad-function-cast warning.
17640 Use a different way to cause a compilation error if anyone uses
17641 n rather than nn, a way that does not involve shadowing.
17642 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
17644 * deps.mk (unexalpha.o): Remove; unused.
17646 New file unexec.h, the (simple) interface for unexec (Bug#8267).

17721 ENABLE_CHECKING is not defined.
17723 * data.c (Findirect_variable): Name an expression, to avoid
17724 gcc -Wbad-function-cast warning.

17741 (Fmemory_limit): Cast sbrk's returned value to char *.

17767 (RETALLOC_IF): Define only if needed.
17768 (WORDCHAR_P): Likewise. This one is never needed, but is used
17769 only in a comment talking about a compiler bug, so put inside
17770 the #if 0 of that comment.

17799 New macros, so that the caller can use some names other than
17800 gcpro1, gcpro2, etc.
17801 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
17803 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
17804 argument, for consistency with GCPRO2_VAR, etc: it is now the
17805 prefix of the variable, not the variable itself. All uses
17807 * dired.c (directory_files_internal, file_name_completion):
17808 Rename locals to avoid shadowing.
17810 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
17811 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
17812 dired.c's scmp function, had undefined behavior.
17813 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
17814 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
17815 * buffer.h: ... to here, because these macros use current_buffer,
17816 and the new implementation with inline functions needs to have
17817 current_buffer in scope now, rather than later when the macros
17819 (downcase, upcase1): New static inline functions.
17820 (DOWNCASE, UPCASE1): Reimplement using these functions.
17821 This avoids undefined behavior in expressions like
17822 DOWNCASE (x) == DOWNCASE (y), which previously suffered
17823 from race conditions in accessing the global variables
17824 case_temp1 and case_temp2.
17825 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.

17852 so that gcc does not warn that these functions aren't declared.

17855 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

17862 * buffer.c (fix_overlays_before): Mark locals as initialized.
17863 (fix_start_end_in_overlays): Likewise. This function should be
17864 simplified by using pointers-to-pointers, but that's a different

17868 (report_overlay_modification): Rename locals to avoid shadowing.

17873 to suppress a gcc -Wclobbered warning that does not seem to be right.
17874 (MAXPATHLEN): Define only if needed.
17876 * process.c (serial_open, serial_configure): Move decls from here ...
17877 * systty.h: ... to here, so that they can be checked.
17879 * fns.c (get_random, seed_random): Move extern decls from here ...
17880 * lisp.h: ... to here, so that they can be checked.
17882 * sysdep.c (reset_io): Now static.
17883 (wait_for_termination_signal): Remove; unused.
17885 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

17890 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
17891 (describe_map_tree):
17892 Rename locals to avoid shadowing.
17894 * keyboard.c: Declare functions static if they are not used elsewhere.

18235 (decode_coding_emacs_mule): Mark variables that gcc
18236 -Wuninitialized does not deduce are never used uninitialized.
18237 (detect_coding_iso_2022): Initialize a local variable that might
18238 be used uninitialized. Leave a FIXME because it's not clear that
18239 this initialization is needed. (Bug#8211)
