13 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
15 Improve sys_siglist detection.
16 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
17 defined as a macro, as is done in Solaris.
18 (sys_siglist_entries): New macro.
19 (save_strsignal): Use it.
20 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
21 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
23 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
25 * nsfns.m (Fx_create_frame): Call x_default_parameter with
26 fullscreen/Fullscreen.

31 * nsterm.m (x_make_frame_visible): Check for fullscreen.
32 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
33 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
34 (windowDidResize:): Check for correct window if old style fullscreen.
35 Capitalize word in comment. Remove incorrect comment.
36 (initFrameFromEmacs:): tbar_height renamed tibar_height.
37 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
38 error in drawing background.
39 (toggleFullScreen:): Remove comment. Rearrange calls.
40 Set toolbar values to zero, save old height in tobar_height.
41 Restore tool bar height when leaving fullscreen.
42 (canBecomeMainWindow): New function.
44 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
46 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
48 2012-10-05 Eli Zaretskii <eliz@gnu.org>
50 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
52 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
53 that time stamps of directories could also be changed. Don't
54 request the too broad GENERIC_WRITE, only the more restrictive
55 FILE_WRITE_ATTRIBUTES access rights.
57 * fileio.c (Fset_file_times): Special-case ignoring errors for
58 directories only on MSDOS, not on MS-Windows.
60 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
62 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
64 2012-10-04 Eli Zaretskii <eliz@gnu.org>
66 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
67 see whether CreateFile failed.
69 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
71 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
72 to avoid similar races.
73 * keyboard.c (pending_signals): Now bool, not int.
75 Port timers to OpenBSD, plus check for timer failures.
76 OpenBSD problem reported by Han Boetes.
77 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
79 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
80 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
81 like OpenBSD, which has timer_settime but does not declare it.
82 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
83 whether to use itimerspec-related primitives. All uses of
84 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
86 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
88 * profiler.c (handle_profiler_signal): Fix a malloc race
89 that caused Emacs to hang on Fedora 17 when profiling Lisp.

98 consistent with the change in return value of 'safe_strsignal'.
100 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
102 Prefer plain 'static' to 'static inline' (Bug#12541).
103 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
104 (bidi_set_sor_type, bidi_push_embedding_level)
105 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
106 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)

110 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
111 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
112 Now 'static', not 'static inline'.
114 Count overruns when profiling; change units to ns.
115 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
116 Give extra weight to samples after overruns, to attempt to count
117 the time more accurately.
118 (setup_cpu_timer): Change sampling interval units from ms to ns, since
119 the underlying primitives nominally do ns.
120 (Fprofiler_cpu_start): Document the change. Mention that
121 the sampling intervals are only approximate.
123 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
125 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
127 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
128 case for the special 0 coding-system.
130 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
131 (Fmake_overlay): Remove redundant tests.
132 (fix_start_end_in_overlays): Remove redundant recentering.
134 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
136 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
139 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
141 Fix a malloc race condition involving strsignal.
142 A signal can arrive in the middle of a malloc, and Emacs's signal
143 handler can invoke strsignal, which can invoke malloc, which is
144 not portable. This race condition bug makes Emacs hang on GNU/Linux.
145 Fix it by altering the signal handler so that it does not invoke
147 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
148 * process.c (status_message): Use const pointer, in case strsignal
149 is #defined to safe_strsignal.
150 * sysdep.c (sys_siglist, init_signals): Always define and
151 initialize a substitute sys_siglist if the system does not define
152 one, even if HAVE_STRSIGNAL.
153 (safe_strsignal): Rename from strsignal. Always define,
154 using sys_siglist. Return a const pointer.
155 * syssignal.h (safe_strsignal): New decl.
156 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
158 2012-10-01 Eli Zaretskii <eliz@gnu.org>
160 * w32proc.c (timer_loop): Fix code that waits for timer
161 expiration, to avoid high CPU usage.
163 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
165 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
166 (sweep_weak_table): Remove redundant prototypes.
168 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
170 * emacs.c: Move the inclusion of TERM_HEADER after including
171 windows.h on WINDOWSNT. This avoids compilation problems with
174 2012-10-01 Eli Zaretskii <eliz@gnu.org>
176 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
177 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
178 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
179 as the previous version used 'void *'.
181 * ralloc.c (ROUNDUP): Fix last change.
182 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
185 * w32proc.c <disable_itimers>: New static flag.
186 (init_timers): Initialize it to zero, after creating the critical
187 sections used by the timer threads.
188 (term_timers): Set to 1 before deleting the critical sections.
189 (getitimer, setitimer): If disable_itimers is non-zero, return an
190 error indication without doing anything. Reported by Fabrice
191 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
192 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
194 [!HAVE_SETITIMER]: Behave as the previous version that didn't
197 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
198 term_ntproc after all the other bookkeeping, to get timers working
201 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
203 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
204 Suggested by Juri Linkov in
205 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
207 Prefer plain 'static' to 'static inline' (Bug#12541).
208 With static functions, modern compilers inline pretty well by
209 themselves; advice from programmers often hurts as much as it helps.
210 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
211 this change shrinks the text size of the Emacs executable by 1.1%
212 without affecting CPU significantly in my benchmark.

293 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
295 Revert the FOLLOW-SYMLINKS change for file-attributes.
296 Doing it right would require several changes to Tramp, and there's

298 * dired.c (directory_files_internal, Ffile_attributes):
301 * frame.c (x_report_frame_params): Port better to wider ints.

473 2012-09-30 Chong Yidong <cyd@gnu.org>
475 * fns.c (Frandom): Doc fix.
477 2012-09-30 Martin Rudalics <rudalics@gmx.at>
479 * window.c (Vwindow_combination_limit): New default value.
480 (Qwindow_size): New symbol replacing Qtemp_buffer_resize.
482 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
484 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
485 Suggested by Eli Zaretskii in
486 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
488 2012-09-30 Eli Zaretskii <eliz@gnu.org>
490 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
491 HAVE_TIMER_SETTIME is defined.
493 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
495 Profiler improvements: more-accurate timers, overflow checks.
496 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
497 signal.h, setjmp.h. Include systime.h instead.
498 (saturated_add): New function.
499 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
500 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
501 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
503 (enum profiler_cpu_running): New enum.
504 (profiler_cpu_running): Now of that enum type, not bool.
505 All uses changed to store the new value.
506 (handle_profiler_signal): Rename from sigprof_handler_1,
507 for consistency with other handlers. Do not check whether
508 cpu_log is a hash-table if garbage collecting, since it
509 doesn't matter in that case.
510 (deliver_profiler_signal): Rename from sigprof_handler,
511 for consistency with other handlers.
512 (setup_cpu_timer): New function, with much of what used to be in
513 Fprofiler_cpu_start. Check for out-of-range argument.
514 Prefer timer_settime if available, and prefer
515 thread cputime clocks, then process cputime clocks, then
516 monotonic clocks, to the old realtime clock. Use make_timeval
517 to round more-correctly when falling back to setitimer.
518 (Fprofiler_cpu_start): Use it.
519 (Fprofiler_cpu_stop): Prefer timer_settime if available.
520 Don't assume that passing NULL as the 2nd argument of setitimer
521 is the same as passing a pointer to all-zero storage.
522 Ignore SIGPROF afterwards.
523 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
524 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
525 non-fatal signal handlers. Ignore SIGPROF on startup.
526 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
527 in profiler.c, since sysdep.c now uses it.
529 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
530 Suggested by Eli Zaretskii in
531 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

542 * alloc.c (Fgarbage_collect):
543 * eval.c (interactive_p, Fsignal, eval_sub, Ffuncall, Fbacktrace)
544 (Fbacktrace_frame): Adjust accordingly.
546 2012-09-28 Glenn Morris <rgm@gnu.org>
548 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
549 (Frun_hook_with_args_until_failure): Doc fixes.
551 2012-09-28 Eli Zaretskii <eliz@gnu.org>
553 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
554 Qautomatic_redisplay and change the symbol name. All users changed.
556 2012-09-28 Tomohiro Matsuyama <tomo@cx4a.org>
558 * profiler.c (sigprof_handler): Fix race condition.
560 2012-09-28 Glenn Morris <rgm@gnu.org>

567 * Makefile.in (LIB_TIMER_TIME): New macro.
569 * atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
570 Use HAVE_TIMER_SETTIME, not SIGEV_SIGNAL, to decide whether to
573 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
575 * profiler.c (Fprofiler_cpu_start): Remove unnecessary flag SA_SIGINFO.
577 2012-09-26 Juanma Barranquero <lekktu@gmail.com>
579 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
581 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
583 * character.h (MAYBE_UNIFY_CHAR): Remove.
584 * charset.c, charset.h (maybe_unify_char): Now static.
585 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
586 Since this stuff is now private to charset.c, there's no need for
587 a public macro and no need to inline by hand.
589 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
590 Stefan Monnier <monnier@iro.umontreal.ca>

602 (Fgarbage_collect): Use it. Record itself in backtrace_list.
603 Call malloc_probe for the memory profiler.
604 (syms_of_alloc): Define Qautomatic_gc.
605 * eval.c (eval_sub, Ffuncall): Reorder assignments to avoid
607 (struct backtrace): Move definition...
608 * lisp.h (struct backtrace): ..here.
609 (Qautomatic_gc, profiler_memory_running): Declare vars.
610 (malloc_probe, syms_of_profiler): Declare functions.

620 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
622 Prefer POSIX timers if available.
623 They avoid a race if the timer is too close to the current time.
624 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
625 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
626 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
628 2012-09-25 Eli Zaretskii <eliz@gnu.org>

639 * lisp.h (reset_image_types): Declare.
640 [WINDOWSNT] (Vlibrary_cache): Declare.
642 * image.c (reset_image_types): New function.
644 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.
645 (syms_of_emacs) [WINDOWSNT] <Vlibrary_cache>: Initialize and staticpro.
646 (Fdump_emacs): Reset Vlibrary_cache and image_types.
648 * w32.c (Vlibrary_cache): Do not define; moved to emacs.c
649 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
651 * w32.h (Vlibrary_cache): Do not declare.
653 2012-09-25 Eli Zaretskii <eliz@gnu.org>
655 * w32proc.c (sys_signal): Handle all signals defined by the
656 MS-Windows runtime, not just SIGCHLD. Actually install the signal
657 handlers for signals supported by Windows. Don't override
658 term_ntproc as the handler for SIGABRT.
659 (sigaction): Rewrite to call sys_signal instead of duplicating its
661 (sys_kill): Improve commentary.
663 * w32.c (term_ntproc): Accept (and ignore) one argument, for
664 consistency with a signature of a signal handler. All callers
666 (init_ntproc): Accept an argument DUMPING. If dumping, don't
667 install term_ntproc as a signal handler for SIGABRT, as that
668 should be done by the dumped Emacs.
670 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
672 * w32select.c (term_w32select): Protect against repeated
673 invocation by setting clipboard_owner to NULL after calling
676 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
677 and term_ntproc to their modified signatures.
679 * character.c (char_string, string_char): Remove calls to
680 MAYBE_UNIFY_CHAR. See the discussion starting at
681 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
684 2012-09-25 Chong Yidong <cyd@gnu.org>

691 when encountering an unknown bytecode.
693 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
695 image.c, indent.c: Use bool for booleans.
696 * dispextern.h (struct image_type): Members valid_p, load, init
697 now return bool, not int. All uses changed.
698 * image.c: Omit unnecessary static decls.
699 (x_create_bitmap_mask, x_build_heuristic_mask):
700 Return void, not int, since callers don't care about the return value.

733 * chartab.c (Fset_char_table_default): Obsolete function removed.
735 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
737 Move pid_t related decls out of lisp.h.
738 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
739 (interruptible_wait_for_termination):
740 Move these decls from lisp.h to syswait.h, since they use pid_t.
741 Needed on FreeBSD; see Herbert J. Skuhra in
742 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
743 * callproc.c: Include syswait.h.

763 Use bool for boolean.
764 * gtkutil.c (xg_update_frame_menubar):
765 * xmenu.c (update_frame_menubar):
766 Return void, not int, since caller ignores return value.

789 2012-09-23 Eli Zaretskii <eliz@gnu.org>
791 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
792 fatal_error_backtrace.
794 * w32proc.c (sys_kill): Undo last change: don't do anything when
795 invoked to deliver SIGABRT to our own process. This is now
796 handled by emacs_raise.
798 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
800 * w32term.c (w32_read_socket): Remove leftover reference to
801 interrupt_input_pending.
803 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
805 Do not use SA_NODEFER.
806 Problem reported by Dani Moncayo in
807 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
809 * sysdep.c (emacs_abort): Do not reset signal handler.
810 * emacs.c (terminate_due_to_signal): Reset signal handler here.
811 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
812 wanted even on POSIXish hosts, and it doesn't work on Windows.
814 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
816 * xterm.c (x_term_init): Call fixup_locale before and after calling
817 gtk_init (Bug#12392).
819 2012-09-23 Chong Yidong <cyd@gnu.org>
821 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
822 Vdynamic_library_alist.
824 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
825 (Fgnutls_available_p): Caller changed.
827 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
828 (Flibxml_parse_xml_region): Likewise.
830 * dispextern.h (struct image_type): Remove arg from init function.
832 * image.c (Finit_image_library, lookup_image_type)
833 (define_image_type): Remove now-unneeded second arg.
834 (init_xpm_functions, init_png_functions, init_jpeg_functions)
835 (init_tiff_functions, init_gif_functions, init_svg_functions):
836 Arglist and w32_delayed_load calling convention changed.
837 (gs_type): Remove init_gs_functions; there is no such function.
838 (valid_image_p, make_image): Fix caller to lookup_image_type.
840 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
842 Simplify and avoid signal-handling races (Bug#12471).
844 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
845 Avoid recursive loop if there's a fatal error in the function itself.
846 * atimer.c (pending_atimers):
847 * blockinput.h: Don't include "atimer.h"; no longer needed.
848 (interrupt_input_pending): Remove. All uses removed.
849 pending_signals now counts both atimers and ordinary interrupts.
850 This is less racy than having three separate pending-signal flags.
851 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
853 Rename from their upper-case counterparts BLOCK_INPUT,
854 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
855 INPUT_BLOCKED_P, and turn into functions. All uses changed.
856 This makes it easier to access volatile variables more accurately.
857 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
858 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
859 that's more reliable if the code is buggy and sets
860 interrupt_input_blocked to a negative value. All uses changed.
861 * atimer.c (deliver_alarm_signal):
862 Remove. No need to deliver this to the parent; any thread can
863 handle this signal now. All uses replaced by underlying handler.
864 * atimer.c (turn_on_atimers):
865 * dispnew.c (handle_window_change_signal):
866 * emacs.c (handle_danger_signal):
867 * keyboard.c (kbd_buffer_get_event):
868 Don't reestablish signal handler; not needed with sigaction.
869 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
871 Rework to avoid unnecessary accesses to volatile variables.
872 (UNBLOCK_INPUT_TO): Now a function.
873 (totally_unblock_input, unblock_input): New decls.
874 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
875 (init_data): Remove. Necessary stuff now done in init_signal.
876 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
877 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
878 (fatal_error_code): Remove; no longer needed.
879 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
880 it doesn't always backtrace. All uses changed. No need to reset
881 signal to default, since sigaction and/or die does that for us now.
882 Use emacs_raise (FOO), not kill (getpid (), FOO).
883 (main): Check more-accurately whether we're dumping.
884 Move fatal-error setup to sysdep.c
885 * floatfns.c: Do not include "syssignal.h"; no longer needed.
886 * gtkutil.c (xg_get_file_name, xg_get_font):
887 Remove no-longer-needed signal-mask manipulation.
888 * keyboard.c, process.c (POLL_FOR_INPUT):
889 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
890 * keyboard.c (read_avail_input): Remove.
891 All uses replaced by gobble_input.
892 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
893 (kbd_buffer_store_event_hold, gobble_input):
894 (record_asynch_buffer_change) [USABLE_SIGIO]:
895 (store_user_signal_events):
896 No need to mess with signal mask.
897 (gobble_input): If blocking input and there are terminals, simply
898 set pending_signals to 1 and return. All hooks changed to not
899 worry about whether input is blocked.
900 (process_pending_signals): Clear pending_signals before processing
901 them, in case a signal comes in while we're processing.
902 By convention callers now test pending_signals before calling us.
903 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
904 New functions, to support changes to blockinput.h.
905 (handle_input_available_signal): Now extern.
906 (reinvoke_input_signal): Remove. All uses replaced by
908 (quit_count): Now volatile, since a signal handler uses it.
909 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
910 All callers changed. Block SIGINT only if not already blocked.
911 Clear sigmask reliably, even if Fsignal returns, which it can.
912 Omit unnecessary accesses to volatile var.
913 (quit_throw_to_read_char): No need to restore sigmask.
914 * keyboard.c (gobble_input, handle_user_signal):
915 * process.c (wait_reading_process_output):
916 Call signal-handling code rather than killing ourselves.
917 * lisp.h: Include <float.h>, for...
918 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
919 (pending_signals): Now volatile.
920 (syms_of_data): Now const if IEEE floating point.
921 (handle_input_available_signal) [USABLE_SIGIO]:
922 (terminate_due_to_signal, record_child_status_change): New decls.
923 * process.c (create_process): Avoid disaster if memory is exhausted
924 while we're processing a vfork, by tightening the critical section
926 (send_process_frame, process_sent_to, handle_pipe_signal)
927 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
929 (send_process): No need for setjmp/longjmp any more, since the
930 SIGPIPE stuff is now gone. Instead, report an error if errno
932 (record_child_status_change): Now extern. PID and W are now args.
933 Return void, not bool. All callers changed.
934 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
935 Remove. All uses removed. This bug should be fixed now in a
937 (wait_for_termination_1): Use waitpid rather than sigsuspend,
938 and record the child status change directly. This avoids the
939 need to futz with the signal mask.
940 (process_fatal_action): Move here from emacs.c.
941 (emacs_sigaction_flags): New function, containing
942 much of what used to be in emacs_sigaction_init.
943 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
944 caught by emacs, to make races less likely.
945 (deliver_process_signal): Rename from handle_on_main_thread.
947 (BACKTRACE_LIMIT_MAX): Now at top level.
948 (thread_backtrace_buffer, threadback_backtrace_pointers):
950 (deliver_thread_signal, deliver_fatal_thread_signal):
951 New functions, for more-accurate delivery of thread-specific signals.
952 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
953 (deliver_arith_signal): Handle in this thread, not
954 in the main thread, since it's triggered by this thread.
955 (maybe_fatal_sig): New function.
956 (init_signals): New arg DUMPING so that we can be more accurate
957 about whether we're dumping. Caller changed.
958 Treat thread-specific signals differently from process-general signals.
959 Block all signals while handling fatal error; that's safer.
960 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
962 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
963 Ignore SIGPIPE unless batch.
964 (emacs_backtrace): Output backtrace for the appropriate thread,
965 which is not necessarily the main thread.
966 * syssignal.h: Include <stdbool.h>.
967 (emacs_raise): New macro.
968 * xterm.c (x_connection_signal): Remove; no longer needed
969 now that we use sigaction.
970 (x_connection_closed): No need to mess with sigmask now.
971 (x_initialize): No need to reset SIGPIPE handler here, since
972 init_signals does this for us now.
974 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
976 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
977 background rect may be larger (Bug#12245).
979 2012-09-23 Chong Yidong <cyd@gnu.org>
981 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
983 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
985 * .gdbinit: Just stop at fatal_error_backtrace.
986 See Stefan Monnier's request in
987 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
988 Remove no-longer-used query of system type.
990 2012-09-22 Chong Yidong <cyd@gnu.org>
992 * search.c (Freplace_match): Doc fix (Bug#12325).
994 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
996 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
997 (Fline_end_position): Doc fix.
999 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
1001 2012-09-22 Chong Yidong <cyd@gnu.org>
1003 * dispextern.h (struct image_type): Add new slot, storing a type
1004 initialization function.
1006 * image.c (define_image_type): Call the image initializer function
1007 if it is defined. Arguments and return value changed.
1008 (valid_image_p, make_image): Callers changed.
1009 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
1010 (gif_type, imagemagick_type, svg_type, gs_type):
1011 Add initialization functions.
1012 (Finit_image_library): Call lookup_image_type.
1013 (CHECK_LIB_AVAILABLE): Macro deleted.
1014 (lookup_image_type): Call define_image_type here, rather than via
1015 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
1016 (syms_of_image): Move define_image_type calls for xbm_type and
1017 pbm_type to lookup_image_type.
1019 2012-09-22 Eli Zaretskii <eliz@gnu.org>
1021 * keyboard.c (timer_check_2): Move calculation of 'timers' and
1022 'idle_timers' from here ...
1023 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
1024 lists, to avoid infloops when the timer does something stupid,
1025 like reinvoke itself with the same or smaller time-out.
1028 2012-09-22 Martin Rudalics <rudalics@gmx.at>
1030 * window.c (Fsplit_window_internal): Handle only Qt value of
1031 Vwindow_combination_limit separately.
1032 (Qtemp_buffer_resize): New symbol.
1033 (Vwindow_combination_limit): New default value.
1036 2012-09-22 Eli Zaretskii <eliz@gnu.org>
1038 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
1039 the new overlay string. (Bug#10159)
1041 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1043 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
1044 or that fprintf is async-signal-safe. POSIX doesn't require
1047 2012-09-22 Chong Yidong <cyd@gnu.org>
1049 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
1052 2012-09-22 Kenichi Handa <handa@gnu.org>
1054 * composite.c (composition_reseat_it): Handle the case that a
1055 grapheme cluster is not covered by a single font (Bug#12352).
1057 2012-09-21 Chong Yidong <cyd@gnu.org>
1059 * image.c (define_image_type): Avoid adding duplicate types to
1060 image_types (Bug#12463). Suggested by Jörg Walter.
1062 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1064 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
1065 (print_load_command_name): Add case LC_DATA_IN_CODE.
1066 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
1068 2012-09-21 Glenn Morris <rgm@gnu.org>
1070 * eval.c (Frun_hook_with_args_until_success)
1071 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
1073 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
1075 * fileio.c (Ffile_selinux_context): Only call freecon when
1076 lgetfilecon succeeded.
1077 (Fset_file_selinux_context): Likewise. (Bug#12444)
1079 2012-09-21 Eli Zaretskii <eliz@gnu.org>
1081 * xdisp.c (try_window_reusing_current_matrix): Under bidi
1082 reordering, locate the cursor by calling set_cursor_from_row; if
1083 that fails, clear the desired glyph matrix before returning a
1084 failure indication to the caller. Fixes leaving garbled display
1085 when fast scrolling with a down-key. (Bug#12403)
1086 (compute_stop_pos_backwards): Fix a typo that caused crashes while
1087 scrolling through multibyte text.
1089 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
1091 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
1092 calling mark_vectorlike since that's the one that marks the window.
1093 (mark_discard_killed_buffers): Mark the final cdr.
1094 * window.h (struct window): Move prev/next_buffers to the
1095 non-standard fields.
1096 * window.c (make_window): Initialize prev/next_buffers manually.
1098 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
1100 Omit unused arg EXPECTED from socket hooks.
1101 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
1102 * nsterm.m (ns_term_init):
1103 * termhooks.h (struct terminal.read_socket_hook):
1104 * w32inevt.c (w32_console_read_socket):
1105 * w32term.c (w32_read_socket):
1106 * xterm.c (XTread_socket):
1107 Omit unused arg EXPECTED. All callers changed.
1108 (store_user_signal_events): Return void, not int, since callers no
1109 longer care about the return value. All uses changed.
1111 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
1113 * w32gui.h (XParseGeometry): Do not declare.
1115 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
1117 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
1118 Ignore 'expected'. See Eli Zaretskii in
1119 <http://bugs.gnu.org/12471#8> (last line).
1121 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
1122 (XParseGeometry): Now static. Substitute extremal values for
1123 values that are out of range.
1125 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
1127 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
1129 * nsfns.m (XParseGeometry): Remove.
1130 (Fx_create_frame): Call x_set_offset to correctly interpret
1131 top_pos in geometry.
1133 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
1134 (Fx_parse_geometry): If there is a space in string, call
1135 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
1137 2012-09-17 Eli Zaretskii <eliz@gnu.org>
1139 * search.c (scan_buffer): Use character positions in calls to
1140 region_cache_forward and region_cache_backward, not byte
1141 positions. (Bug#12196)
1143 * w32term.c (w32_read_socket): Set pending_signals to 1, like
1144 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
1146 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
1147 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
1148 emacs_blocked_malloc, now deleted.
1150 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
1152 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
1153 The workaround was for improving performance on Solaris 2.4, but
1154 is getting in the way now. Emacs will still work if someone is
1155 still running Solaris 2.4 in a museum somewhere; Sun dropped
1156 support for Solaris 2.4 in 2003.
1157 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
1158 * process.c (create_process) [HAVE_WORKING_VFORK]:
1159 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
1160 since Emacs no longer uses vfork on that platform.
1162 2012-09-17 Glenn Morris <rgm@gnu.org>
1164 * emacs.c: Use COPYRIGHT.
1166 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
1168 Remove configure's --without-sync-input option (Bug#12450).
1169 When auditing signal-handling in preparation for cleaning it up,
1170 I found that SYNC_INPUT has race conditions and would be a real
1171 pain to fix. Since it's an undocumented and deprecated
1172 configure-time option, now seems like a good time to remove it.
1173 Also see <http://bugs.gnu.org/11080#16>.
1174 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
1175 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
1176 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
1177 (malloc_hysteresis):
1178 (check_depth) [XMALLOC_OVERRUN_CHECK]:
1179 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
1180 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
1181 (dont_register_blocks, bytes_used_when_reconsidered)
1182 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
1183 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
1184 [!SYSTEM_MALLOC && !SYNC_INPUT]:
1185 Remove. All uses removed.
1186 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
1187 implementation, one that depends on whether the new macro
1188 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
1190 * atimer.c (run_timers, handle_alarm_signal):
1191 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
1192 (handle_async_input, process_pending_signals)
1193 (handle_input_available_signal, init_keyboard):
1194 * nsterm.m (ns_read_socket):
1195 * process.c (wait_reading_process_output):
1196 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
1197 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
1199 * xterm.c (XTread_socket):
1201 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
1202 * eval.c (handling_signal): Remove. All uses removed.
1203 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
1204 All uses replaced with the SYNC_INPUT version.
1205 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
1207 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1210 * font.c (Ffont_shape_gstring): Remove unused local.
1212 2012-09-16 Glenn Morris <rgm@gnu.org>
1214 * Makefile.in (clean): No longer run nextstep's clean.
1216 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
1218 (ns-app): Move here from ns.mk, and simplify.
1219 (clean): Simplify nextstep entry.
1220 * ns.mk: Remove file.
1222 2012-09-17 Kenichi Handa <handa@gnu.org>
1224 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
1225 not covert the last few charactes.
1227 2012-09-16 Kenichi Handa <handa@gnu.org>
1229 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
1230 here, but just check the validity of glyphs in the glyph-string.
1232 2012-09-16 Martin Rudalics <rudalics@gmx.at>
1234 * window.c (Fwindow_parameter, Fset_window_parameter):
1235 Accept any window as argument (Bug#12452).
1237 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
1239 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
1240 to ns_term_init to avoid memory leak.
1242 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
1243 explicit retain/release.
1244 (ns_term_init): Only allow one display. Initialize outerpool and
1247 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1249 Port _setjmp fix to POSIXish hosts as well as Microsoft.
1250 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
1251 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
1252 the Microsoft problem in a different way, by altering ../nt/config.nt.
1254 2012-09-15 Eli Zaretskii <eliz@gnu.org>
1269 * w16select.c: Remove inclusion of setjmp.h, as it is now included
1270 by lisp.h. This completes removal of setjmp.h inclusion
1271 erroneously announced in the previous commit. (Bug#12446)
1273 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
1276 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
1277 not defined as a macro. The latter happens on MS-Windows.
1280 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1282 Port better to POSIX hosts lacking _setjmp (Bug#12446).
1283 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
1284 Some instances of '#include <setjmp.h>' removed, if the
1285 only reason for the instance was because "lisp.h" was included.
1286 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
1287 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
1288 and _longjmp with the new symbols. Emacs already uses _setjmp if
1289 available, so this change affects only POSIXish hosts that have
1290 sigsetjmp but not _setjmp, such as some versions of Solaris and
1291 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
1292 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
1293 (png_load_body) [HAVE_PNG]:
1294 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
1295 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
1296 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
1297 since PNG requires jmp_buf. This is the only exception to the
1298 general rule that we now use sys_setjmp and sys_longjmp.
1299 This exception is OK since this code does not change the signal
1300 mask or longjmp out of a signal handler.
1302 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
1304 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
1305 Include "syssignal.h", for 'main_thread'.
1307 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
1309 Avoid out-of-range marker position (Bug#12426).
1310 * insdel.c (replace_range, replace_range_2):
1311 Adjust markers before overlays, as suggested by comments.
1312 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
1313 Remove redundant check before calling offset_intervals.
1315 2012-09-14 Martin Rudalics <rudalics@gmx.at>
1317 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
1318 current buffer (Bug#12387).
1320 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
1322 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
1324 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
1326 Use a more backwards-compatible timer format (Bug#12430).
1327 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
1328 vector element, not from the 4th, since PSECS is now at the end.
1329 (Fcurrent_idle_time): Doc fix.
1331 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
1333 Function to mark objects and remove killed buffers at once.
1334 * alloc.c (discard_killed_buffers): Rename to ...
1335 (mark_discard_killed buffers) ... new name. Add marking
1336 of remaining objects. Fix comment. Adjust users.
1337 (mark_object): Do not touch frame buffer lists here.
1338 * frame.c (delete_frame): Reset frame buffer lists here.
1340 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
1342 Better workaround for GNOME bug when --enable-gcc-warnings.
1343 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
1344 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
1345 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
1347 Simplify SIGIO usage (Bug#12408).
1348 The code that dealt with SIGIO was crufty and confusing, e.g., it
1349 played tricks like "#undef SIGIO" but these tricks were not used
1350 consistently. Simplify mostly by not #undeffing standard symbols,
1351 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
1352 or not as we please) rather than "defined SIGIO" (standard symbol
1353 that we probably shouldn't #undef).
1354 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
1355 Modules that need it can include it.
1356 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
1357 * dispextern.h (ignore_sigio): New decl.
1358 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
1359 unconditionally, since it's now a no-op if !USABLE_SIGIO.
1360 * emacs.c (shut_down_emacs):
1361 * keyboard.c (kbd_buffer_store_event_hold):
1362 Use ignore_sigio rather than invoking 'signal' directly.
1363 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
1365 (FIONREAD, SIGIO): Do not #undef.
1366 (tty_read_avail_input): Use #error rather than a syntax error.
1367 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
1368 for I_PIPE, used by SETUP_SLAVE_PTY.
1369 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
1370 * sysdep.c (croak): Remove; no longer needed. This bit of
1371 temporary code, with Fred N. Fish's comment that it's temporary,
1372 has been in Emacs since at least 1992!
1373 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
1374 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
1375 * syssignal.h (croak): Remove decl.
1376 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
1377 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
1378 now that we're termios-only.
1379 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
1380 * term.c (dissociate_if_controlling_tty): Use #error rather than
1383 Work around GCC and GNOME bugs when --enable-gcc-warnings.
1384 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
1385 to work around GNOME bug 683906.
1386 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
1387 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
1388 This works around GCC bug 54561.
1390 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
1392 More fixes for 'volatile' and setjmp/longjmp.
1393 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
1394 * image.c (struct png_load_context) [HAVE_PNG]: New type.
1395 (png_load_body) [HAVE_PNG]:
1396 (jpeg_load_body) [HAVE_JPEG]:
1397 New function, with most of the old parent function's body.
1398 (png_load) [HAVE_PNG]:
1399 (jpeg_load) [HAVE_JPEG]:
1400 Invoke the new function, to avoid longjmp munging our locals.
1401 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
1402 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
1403 longjmp is passed 2, as the C standard doesn't guarantee this.
1404 Instead, store the failure code into mgr->failure_code.
1406 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
1408 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
1409 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
1410 (syms_of_keyboard): Remove support for unread-command-char.
1412 2012-09-12 Eli Zaretskii <eliz@gnu.org>
1414 * w32proc.c (sys_kill): If PID is our process ID and the signal is
1415 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
1416 violation. (Bug#12426)
1418 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
1420 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
1422 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
1424 * eval.c: Add `inhibit-debugger'.
1425 (Qinhibit_debugger): New symbol.
1426 (call_debugger): Bind it instead of Qdebug_on_error.
1427 (maybe_call_debugger): Test Vinhibit_debugger.
1428 (syms_of_eval): Define inhibit-debugger.
1429 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
1430 (syms_of_xdisp): Remove inhibit-debug-on-message.
1432 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
1434 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
1435 If a nonvolatile local variable is written before a _longjmp to
1436 the frame containing the variable, and is read after the _longjmp,
1437 the value read is indeterminate. Some local variables of type
1438 'struct handler' and 'struct catchtag' are used in this way, so
1439 mark each of their slots as volatile if the slot can be set before
1440 _longjmp and read afterwards.
1441 * lisp.h (struct handler): var and chosen_clause are now volatile.
1442 (struct catchtag): val, next, and pdlcount are now volatile.
1444 * bidi.c (bidi_push_it, bidi_pop_it):
1445 * fns.c (copy_hash_table):
1446 * image.c (define_image_type):
1447 * keyboard.c (kbd_buffer_store_event_hold):
1448 * process.c (Fprocess_send_eof):
1449 * xfaces.c (x_create_gc) [HAVE_NS]:
1450 * xgselect.c (xg_select):
1451 Prefer assignment to memcpy when either will do.
1453 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
1454 Use pointer-to-a-pointer to simplify and avoid a NILP check each
1455 time an item is removed. No need to mark this function 'inline';
1456 the compiler knows better than we do.
1458 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
1460 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
1461 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
1462 to change_frame_size (Bug#12388).
1463 (windowDidResize:): Pass YES to updateFrameSize.
1465 * nsterm.h: Add delay parameter to updateFrameSize.
1467 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
1469 Discard killed buffers from deleted window and frame objects.
1470 This reduces an amount of references to killed buffers and
1471 helps GC to reclaim them faster.
1472 * alloc.c (discard_killed_buffers): New function.
1473 (mark_object): Use it for deleted windows and frames.
1474 (mark_object): If symbol's value is set up for a killed buffer
1475 or deleted frame, restore it's global binding.
1476 * data.c (swap_in_global_binding): Add GC notice.
1477 (swap_in_symval_forwarding): Use convenient set_blv_where.
1478 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
1479 * window.h: ... to here.
1481 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
1483 Convenient macro to check whether the buffer is live.
1484 * buffer.h (BUFFER_LIVE_P): New macro.
1485 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
1486 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
1488 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1490 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
1491 composition cases (Bug#12364).
1493 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
1494 overhang of succeeding glyphs overlapping box cursor.
1496 * w32term.c (x_draw_glyph_string): Likewise.
1498 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
1500 Simplify, document, and port floating-point (Bug#12381).
1501 The porting part of this patch fixes bugs on non-IEEE platforms
1502 with frexp, ldexp, logb.
1503 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
1505 * floatfns.c: Simplify discussion of functions that Emacs doesn't
1506 support, by removing commented-out code and briefly listing the
1507 C89 functions excluded. The commented-out stuff was confusing
1508 maintenance, e.g., we thought we needed cbrt but it was commented out.
1509 (logb): Remove decl; no longer needed.
1510 (isfinite): New macro, if not already supplied.
1511 (isnan): Don't replace any existing macro.
1512 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
1513 are present on all C89 platforms.
1514 (Ffrexp): Do not special-case zero, as frexp does the right thing
1516 (Flogb): Do not use logb, as it doesn't have the desired meaning
1517 on hosts that use non-base-2 floating point. Instead, stick with
1518 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
1519 frexp, to avoid getting an unspecified result.
1521 * xdisp.c (Qinhibit_debug_on_message): Now static.
1523 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
1525 * nsterm.m (ns_update_begin): Set clip path to whole view by using
1526 NSBezierPath (Bug#12131).
1528 2012-09-10 Chong Yidong <cyd@gnu.org>
1530 * fns.c (Fdelq, Fdelete): Doc fix.
1532 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
1534 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
1535 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
1537 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
1539 * lisp.h (make_lisp_ptr): New macro to replace XSET.
1540 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
1543 2012-09-09 Eli Zaretskii <eliz@gnu.org>
1545 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
1546 left fringe if the window has a left margin. This avoids leaving
1547 traces of the cursor because its leftmost pixel is not drawn over.
1549 * dispnew.c (update_window_line): When the left margin area of a
1550 screen line is updated, set the redraw_fringe_bitmaps_p flag of
1551 that screen line. (Bug#12277)
1553 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
1555 Assume C89 or later for math functions (Bug#12381).
1556 This simplifies the code, and makes it a bit smaller and faster,
1557 and (most important) makes it easier to clean up signal handling
1558 since we can stop worring about floating-point exceptions in
1559 library code. That was a problem before C89, but the problem
1560 went away many years ago on all practical Emacs targets.
1561 * data.c, image.c, lread.c, print.c:
1562 Don't include <math.h>; no longer needed.
1563 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
1564 might be autoconfigured, as that never happens.
1566 * doprnt.c (DBL_MAX_10_EXP):
1567 * print.c (DBL_DIG):
1568 Remove. C89 or later always defines these.
1569 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
1570 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
1571 (arith_error, domain_error, domain_error2):
1572 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
1573 no longer needed -- we simply return what C returns. All uses removed.
1574 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
1576 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
1577 Remove. All uses expanded, as these macros are no longer used
1578 more than once and are now more trouble than they're worth.
1579 (Ftan): Use tan, not sin / cos.
1580 (Flogb): Assume C89 frexp.
1581 (fmod_float): Assume C89 fmod.
1582 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
1583 (init_floatfns): Remove. All uses removed.
1585 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1587 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
1588 compositeToPoint for OSX < 10.6 (Bug#12390).
1590 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
1592 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
1593 This produces more-accurate results.
1595 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1597 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
1598 changes (Bug#12088).
1600 2012-09-08 Chong Yidong <cyd@gnu.org>
1602 * syntax.c (Fstring_to_syntax): Doc fix.
1604 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1606 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
1607 in the internal border.
1608 (x_set_window_size): Remove static variables and their usage.
1609 (ns_redraw_scroll_bars): Fix NSTRACE arg.
1610 (ns_after_update_window_line, ns_draw_fringe_bitmap):
1611 Remove fringe/internal border adjustment (Bug#11052).
1612 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
1613 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
1614 (ns_fix_rect_ibw): Remove.
1615 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
1616 (ns_dumpglyphs_box_or_relief): Ditto.
1617 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
1619 (ns_dumpglyphs_image): Ditto.
1620 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
1622 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
1623 their usage. Add fringe_extended_p and its use as in other terms.
1624 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
1625 scroll bar was removed.
1626 (updateFrameSize): New function.
1627 (windowDidResize): Move code to updateFrameSize and call it.
1629 * nsterm.h (EmacsView): Add updateFrameSize.
1631 2012-09-07 Chong Yidong <cyd@gnu.org>
1633 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
1635 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
1637 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1639 More signal-handler cleanup (Bug#12327).
1640 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
1641 Problem introduced when merging patches. Noted by Eli Zaretskii in
1642 <http://bugs.gnu.org/12327#67>.
1643 * floatfns.c: Comment fix.
1644 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
1645 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
1646 and anyway the declaration is harmless even if SIGDANGER is not defined.
1647 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
1648 defined BROKEN_FIONREAD). systty.h formerly did this, but other
1649 source files not surprisingly expected syssignal.h to define, or
1650 not define, SIGIO, and it's cleaner to do it that way, for consistency.
1651 Include <sys/ioctl.h>, for FIONREAD.
1652 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
1653 This eliminates a problem whereby other files mysteriously had
1654 to include "syssignal.h" before including "systty.h" if they
1655 wanted to use "#ifdef SIGIO".
1657 2012-09-07 Eli Zaretskii <eliz@gnu.org>
1659 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
1661 * w32.c (sigemptyset): Empty the set.
1662 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
1664 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
1666 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
1668 * alloc.c (mark_buffer): Revert unsafe marking optimization.
1669 (mark_object): Likewise for frame objects.
1671 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1673 * syssignal.h (handle_on_main_thread): Always declare,
1674 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
1675 This ports to platforms without HAVE_PTHREAD.
1677 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1679 Signal-handler cleanup (Bug#12327).
1680 Emacs's signal handlers were written in the old 4.2BSD style with
1681 sigblock and sigmask and so forth, and this led to some
1682 inefficiencies and confusion. Rewrite these to use
1683 pthread_sigmask etc. without copying signal sets around. Also,
1684 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
1685 'signal', and instead use functions that do not attempt to take
1686 over the system name space. This patch causes Emacs's text
1687 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
1688 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
1689 Do not include <signal.h> or "syssignal.h", as these
1690 modules do not use signals.
1691 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
1692 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
1693 Do not include <signal.h>, as "syssignal.h" does that for us now.
1694 * atimer.c (sigmask_atimers): New function.
1695 (block_atimers, unblock_atimers): New functions,
1696 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
1698 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
1699 no longer needed here.
1700 * emacs.c (main): Inspect existing signal handler with sigaction,
1701 so that there's no need to block and unblock SIGHUP.
1702 * sysdep.c (struct save_signal): New member 'action', replacing
1703 old member 'handler'.
1704 (save_signal_handlers, restore_signal_handlers):
1705 Use sigaction instead of 'signal' to save and restore.
1706 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
1707 New function. All users of 'signal' modified to use set_sighandler
1708 if they're writeonly, and to use sys_signal if they're read+write.
1709 (emacs_sigaction_init, forwarded_signal): New functions.
1710 (sys_signal): Remove. All uses replaced by calls to sigaction
1711 and emacs_sigaction_init, or by direct calls to 'signal'.
1712 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
1713 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
1714 all uses replaced by pthread_sigmask etc. calls.
1715 * syssignal.h: Include <signal.h>.
1716 (emacs_sigaction_init, forwarded_signal): New decls.
1717 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
1718 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
1719 (sigmask, sys_sigmask): Remove; no longer needed.
1720 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
1721 (sigblock, sigunblock, sigfree):
1722 (sigsetmask) [!defined sigsetmask]:
1723 Remove. All uses replaced by pthread_sigmask.
1724 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
1725 no longer need to be replaced, and its typical old uses
1726 are now done via emacs_sigaction_init and sigaction.
1727 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
1728 (sys_sigdel): Remove; unused.
1729 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
1731 2012-09-06 Eli Zaretskii <eliz@gnu.org>
1733 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
1734 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
1736 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1738 Explicitly mark buffer_defaults and buffer_local_symbols.
1739 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
1740 mark_local_symbols here.
1741 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
1742 since special buffers aren't marked here any more.
1743 (allocate_buffer): Chain new buffer with all_buffers here...
1744 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
1746 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
1747 (syms_of_buffer): Remove staticpro of the above.
1748 (init_buffer_once): Set names for buffer_defaults and
1749 buffer_local_symbols.
1751 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1753 Use bool for booleans in font-related modules.
1754 * font.c (font_intern_prop, font_style_to_value)
1755 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
1756 (generate_otf_features, font_check_otf_features, font_check_otf)
1757 (font_match_p, font_list_entities, font_at):
1758 * fontset.c (fontset_id_valid_p, reorder_font_vector
1759 (fontset_find_font, Fset_fontset_font)
1760 (face_suitable_for_char_p) [0]:
1761 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
1762 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
1763 (m17n_flt_initialized, ftfont_shape_by_flt):
1764 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
1765 * nsfont.m (nsfont_draw):
1766 * w32font.c (w32font_draw):
1767 * w32term.c (x_draw_glyphless_glyph_string_foreground):
1768 Use bool for booleans.
1769 * font.h: Adjust to above API changes.
1770 (struct font, struct font_driver, struct font_driver_list):
1771 Use bool for booleans.
1772 (struct font): Remove useless member encoding_type.
1774 * fontset.c, xftfont.c: Omit unnecessary static decls.
1776 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1778 * alloc.c (mark_object): Revert window marking code
1779 since it's unsafe for the Fset_window_configuration.
1781 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1783 Fix race conditions with signal handlers and errno (Bug#12327).
1784 Be more systematic about preserving errno whenever a signal
1785 handler returns, even if it's not in the main thread. Do this by
1786 renaming signal handlers to distinguish between signal delivery
1787 and signal handling. All uses changed.
1788 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
1789 * data.c (deliver_arith_signal): Rename from arith_error.
1790 * dispnew.c (deliver_window_change_signal): Rename from
1791 window_change_signal.
1792 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
1793 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
1794 * keyboard.c (deliver_input_available_signal): Rename from
1795 input_available_signal.
1796 (deliver_user_signal): Rename from handle_user_signal.
1797 (deliver_interrupt_signal): Rename from interrupt_signal.
1798 * process.c (deliver_pipe_signal): Rename from send_process_trap.
1799 (deliver_child_signal): Rename from sigchld_handler.
1800 * atimer.c (handle_alarm_signal):
1801 * data.c (handle_arith_signal):
1802 * dispnew.c (handle_window_change_signal):
1803 * emacs.c (handle_fatal_signal, handle_danger_signal):
1804 * keyboard.c (handle_input_available_signal):
1805 * keyboard.c (handle_user_signal, handle_interrupt_signal):
1806 * process.c (handle_pipe_signal, handle_child_signal):
1807 New functions, with the actual signal-handling code taken from the
1808 original respective signal handlers, sans the sporadic attempts to
1809 preserve errno, since that's now done by handle_on_main_thread.
1810 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
1811 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
1812 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1814 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1815 Move initialization of main_thread to sysdep.c's init_signals.
1816 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
1817 our usage, and simplifies the mainline code.
1818 (record_child_status_change): New static function, as a helper
1819 for handle_child_signal, and with most of the old child handler's
1821 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
1822 (handle_child_signal): Use the above.
1823 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1824 Moved here from emacs.c.
1825 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
1826 code moved here from emacs.c's main function.
1827 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
1828 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
1829 This lets callers save and restore errno properly.
1831 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1833 Remove redundant or unused things here and there.
1834 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
1835 * conf_post.h (RE_TRANSLATE): Use char_table_translate.

1837 * frame.h (struct terminal, struct font_driver_list):
1838 Remove redundant declarations.
1839 * window.h (Qleft, Qright): Likewise.
1841 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1843 Do not mark objects from deleted buffers, windows and frames.
1844 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
1845 (mark_object): Likewise for windows and frames.
1847 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1849 * alloc.c (valid_lisp_object_p): Treat killed buffers,
1850 buffer_defaults and buffer_local_symbols as valid objects.
1851 Return special value to denote them.
1853 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1855 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
1856 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
1857 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
1858 (file_name_absolute_p, Fsubstitute_in_file_name):
1859 (check_executable, check_writable, Ffile_accessible_directory_p)
1860 (Fset_file_selinux_context, Fdefault_file_modes)
1861 (Finsert_file_contents, choose_write_coding_system)
1862 (Fwrite_region, build_annotations, a_write, e_write)
1864 * filelock.c (boot_time_initialized, get_boot_time)
1865 (get_boot_time_1, lock_file_1, within_one_second):
1866 * floatfns.c (in_float):
1867 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
1868 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
1869 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
1870 * lisp.h (struct Lisp_Hash_Table.cmpfn):
1871 * window.c (compare_window_configurations):
1872 Use bool for booleans.
1873 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
1874 (Fdefault_file_modes): Now mode_t, not int, for modes.
1875 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
1876 (internal_delete_file): Now returns void, not a (boolean) int,
1877 since nobody was looking at the return value.
1878 * lisp.h, window.h: Adjust to above API changes.
1880 * xdisp.c (set_message): Simplify and reindent last change.
1882 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
1884 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
1886 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
1888 * eval.c (call_debugger): Make the function non-static so that we
1889 can call it from set_message.
1891 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
1892 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
1894 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1896 Give more-useful info on a fatal error (Bug#12328).
1897 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
1898 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
1899 of doing the work ourselves.
1900 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
1901 do most of the work.
1902 (fatal_error_backtrace): New function, taken from the guts
1903 of the old fatal_error_signal, but with a new option to output
1905 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
1906 info about the signal than just its number.
1907 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
1908 * sysdep.c: Include <execinfo.h>
1909 (emacs_backtrace): New function, taken partly from the previous
1910 code of the 'die' function.
1911 (emacs_abort): Call fatal_error_backtrace rather than abort.
1913 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
1915 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
1916 eager (load-time) macro-expansion.

1919 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1921 Simplify redefinition of 'abort' (Bug#12316).
1922 Do not try to redefine the 'abort' function. Instead, redo
1923 the code so that it calls 'emacs_abort' rather than 'abort'.
1924 This removes the need for the NO_ABORT configure-time macro
1925 and makes it easier to change the abort code to do a backtrace.
1926 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
1927 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
1928 Remove; sysdep.c's emacs_abort now takes its place.
1929 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
1930 'abort' changed to use 'emacs_abort'.
1931 * msdos.c (dos_abort) [defined abort]: Remove; not used.
1932 (abort) [!defined abort]: Rename to ...
1933 (emacs_abort): ... new name.
1934 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
1935 the place of the old 'abort' in emacs.c.
1936 * w32.c, w32fns.c (abort): Do not #undef.
1937 * w32.c (emacs_abort): Rename from w32_abort.
1939 2012-09-04 Eli Zaretskii <eliz@gnu.org>
1941 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
1942 offsets[j].dv, since the y axis of the screen coordinates points
1943 down, while the y axis of the font definition coordinates points
1944 up. This fixes display of Arabic diacritics such as KASRA and
1945 KASRATAN. (Bug#11860)
1947 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1949 Be more systematic about _setjmp vs setjmp.
1950 * alloc.c (test_setjmp, mark_stack):
1951 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
1952 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
1953 (png_load, my_error_exit, jpeg_load):
1954 * process.c (send_process_trap, send_process):
1955 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
1956 The underscored versions are up to 30x faster on some hosts.
1957 Formerly, the code used setjmp+longjmp sometimes and
1958 _setjmp+_longjmp at other times, with no particular reason to
1959 prefer setjmp+longjmp.
1961 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
1963 Fix minor problem found by static checking.
1964 * buffer.c (Fdelete_all_overlays): Return nil.
1966 2012-09-03 Martin Rudalics <rudalics@gmx.at>
1968 * buffer.c (Fdelete_all_overlays): New function.
1970 2012-09-03 Chong Yidong <cyd@gnu.org>
1972 * gtkutil.c: Add extern decl for Qxft.
1974 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

1988 All callers changed.
1989 * eval.c (interactive_p): Omit always-true boolean argument
1990 EXCLUDE_SUBRS_P. All callers changed.
1991 * dispextern.h, lisp.h: Reflect above API changes.
1992 * firstfile.c (dummy): Use the address of 'main', whose signature
1993 won't change, instead of the address of 'initialize', whose
1994 signature just changed from int to bool.
1995 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
1996 * msdos.c (fatal_error_in_progress): ... from here.
1997 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
1999 (redisplay_internal, unwind_redisplay): Simply clear
2000 REDISPLAYING_P when unwinding, instead of saving its previous,
2001 always-false value and then restoring it.
2003 Clean up some extern decls.
2004 Mostly, this hoists extern decls out of .c files and into .h files.
2005 That way, we're more likely to catch errors if the interfaces change.
2006 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
2007 declare xg_mark_data.
2008 * dispextern.h (x_frame_parm_handlers):
2010 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
2011 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)

2026 * xfont.c (x_clear_errors):
2027 * xterm.c (x_frame_parm_handlers):
2028 Remove now-redundant extern decls.
2029 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
2030 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
2032 * xfaces.c: Remove unnecessary static decls.
2033 * xterm.c (updating_frame): Remove decl of nonexistent object.
2035 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
2036 when building globals.h, as the objects that are not built on
2037 this host are not needed to compile C files on this host.
2039 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
2041 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

2054 (format_time_string, general_insert_function)
2055 (make_buffer_string, make_buffer_string_both)
2056 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
2057 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)

2067 (get_property_and_range, compare_string_intervals)
2068 (set_intervals_multibyte_1, set_intervals_multibyte):
2069 * keyboard.c (decode_timer):
2070 Use bool for boolean.
2071 * intervals.h, lisp.h, systime.h: Reflect above API changes.
2072 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
2074 2012-09-02 Chong Yidong <cyd@gnu.org>
2076 * keymap.c (push_key_description): Print M-TAB as C-M-i
2079 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
2081 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
2082 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

2087 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
2089 2012-09-01 Eli Zaretskii <eliz@gnu.org>
2091 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
2092 more than one grapheme cluster passed to the shaper: compute the
2093 offset adjustment values separately for each cluster. (Bug#11860)
2095 * image.c: Restore mistakenly removed inclusion of w32.h. Without
2096 it, GCC doesn't see prototypes of w32_delayed_load, and complains
2097 about implicit conversions from integer to pointer.
2099 2012-09-01 Daniel Colascione <dancol@dancol.org>
2101 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
2102 system used too early.
2104 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
2106 Better seed support for (random).

2135 * process.c: Include TERM_HEADER instead of listing all possible
2136 window-system headers.
2138 * nsterm.h: Remove declarations now in frame.h.
2139 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
2141 * menu.c: Include TERM_HEADER instead of listing all possible
2142 window-system headers.
2144 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
2147 * keyboard.c: Include TERM_HEADER instead of listing all possible
2148 window-system headers.
2150 * image.c: Include TERM_HEADER instead of listing all possible
2151 window-system headers. Declare Vlibrary_cache when compiling for
2154 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
2155 window system declarations.
2157 * frame.h: Move common functions here: set_frame_menubar,
2158 x_set_window_size, x_sync, x_get_focus_frame,
2159 x_set_mouse_position, x_set_mouse_pixel_position,
2160 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,
2161 x_char_width, x_char_height, x_pixel_width, x_pixel_height,

2181 the current window system; include in list of objects to link into
2184 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
2186 Remove mark_ttys function and fix tty_display_info initialization.
2187 * lisp.h (mark_ttys): Remove prototype.
2188 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
2189 to mark_ttys because all possible values of 'top_frame' slot are
2190 the frames which are reachable from Vframe_list.
2191 * term.c (mark_ttys): Remove.
2192 (init_tty): Safely initialize 'top_frame' slot with Qnil.
2194 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
2196 Change struct frame bitfields from unsigned char to unsigned.
2197 * frame.h (struct frame): Change type of 'display_preempted',

2199 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
2200 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
2201 bitfields from unsigned char to unsigned.
2203 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
2205 Remove unused member of struct x_output and struct w32_output.

2209 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
2211 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
2212 does not become zero (Bug#12234).
2214 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
2216 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
2217 for GCC 4.7.1 x86-64.
2219 2012-08-30 Glenn Morris <rgm@gnu.org>
2221 * lread.c (init_lread): For out-of-tree builds, only add the
2222 source directory's site-lisp dir to the load-path if it exists,
2223 consistent with in-tree builds. (Bug#12302)
2225 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
2227 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
2228 button_values to NULL. Call setStykeMask so dialogs get a close button.
2229 (windowShouldClose:): Set window_closed.
2230 (dealloc): New member, free button_values.
2231 (process_dialog:): Make member function. Remove window argument,
2232 replace window with self. Count buttons and allocate and store values
2234 (addButton:value:row:): value is int with the name tag. Call setTag
2235 with tag. Remove return self, declare return value as void.
2236 (addString:row:): Remove return self, declare return value as void.
2237 (addSplit): Remove return self, declare return value as void.
2238 (clicked:): Remove return self, declare return value as void.
2239 Set dialog_return to button_values[seltag]. Code formatting change.
2240 (initFromContents:isQuestion:): Adjust call to process_dialog.
2241 Code formatting change.
2242 (timeout_handler:): Set timer_fired to YES.
2243 (runDialogAt:): Set timer_fired to NO.
2244 Handle click on close button as quit.
2246 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
2247 Add window_closed and button_values. Add void as return value for
2248 add(Button|String|Split). addButton takes int instead of Lisp_Object.
2249 Add process_dialog as new member.
2251 2012-08-28 Eli Zaretskii <eliz@gnu.org>
2253 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
2254 is not one of the heaps we manage. (Bug#12242)
2256 2012-08-28 Glenn Morris <rgm@gnu.org>
2258 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)
2260 2012-08-28 Martin Rudalics <rudalics@gmx.at>

2270 if the buffer is dead.
2271 (Fother_buffer, other_buffer_safely): Remove redundant
2274 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
2276 Always use set_buffer_if_live to restore original buffer at unwind.
2277 * buffer.h (record_unwind_current_buffer): New function.
2278 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:
2279 * keyboard.c, keymap.c, minibuf.c, print.c, process.c, textprop.c:
2280 * undo.c, window.c: Adjust users.
2281 * buffer.c (set_buffer_if_live): Fix comment.
2283 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
2285 Fix usage of set_buffer_internal.
2286 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
2287 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
2288 * coding.c (decode_coding): Omit redundant test.
2289 * fileio.c (decide_coding_unwind): Likewise.

2292 * keyboard.c (command_loop_1): Likewise.
2293 * print.c (PRINTFINISH): Likewise.
2294 * xdisp.c (run_window_scroll_functions): Use set_buffer_internal.
2296 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

2316 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
2317 and remove last int (actually boolean) argument, which was always 0.
2318 All callers changed.
2319 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
2320 * dispextern.h (struct composition_it): Use bool for boolean.
2321 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
2322 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
2323 * dired.c (file_name_completion):
2324 Use bool for boolean. (This was missed in an earlier change.)
2326 2012-08-27 Martin Rudalics <rudalics@gmx.at>
2328 * window.c (Fset_window_configuration): Revert first part of
2331 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
2333 * nsterm.h (NSPanel): New class variable dialog_return.
2335 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
2336 Initialize dialog_return.
2337 (windowShouldClose:): Use stop instead of stopModalWithCode.
2338 (clicked:): Ditto, and also set dialog_return (Bug#12258).
2339 (timeout_handler:): Use stop instead of abortModal. Send a dummy
2341 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

2386 Use bool for booleans.
2387 * coding.h, lisp.h: Reflect above API changes.
2388 * coding.c: Remove unnecessary static function decls.
2389 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
2390 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
2391 not a boolean 'int', since callers never look at the return value.
2392 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
2393 * coding.h (decoding_buffer_size, encoding_buffer_size)
2394 (emacs_mule_string_char): Remove unused extern decls.
2395 (struct iso_2022_spec, struct coding_system):
2396 Use 'unsigned int : 1' for boolean fields, since there's more than one.
2397 (struct emacs_mule_spec): Remove unused field 'full_support'.
2398 All initializations removed.
2399 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
2401 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
2403 Fix spare memory change (Bug#12286).
2404 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
2405 (valid_lisp_object_p): Likewise.
2407 2012-08-27 Martin Rudalics <rudalics@gmx.at>
2409 * window.c (Fset_window_configuration): Record any window's old
2410 buffer if it's replaced (see Bug#8789). If the new current
2411 buffer doesn't appear in the selected window, go to its old
2414 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
2416 Special MEM_TYPE_SPARE to denote reserved memory.
2417 * alloc.c (enum mem_type): New memory type.
2418 (refill_memory_reserve): Use new type for spare memory.
2419 This prevents live_cons_p and live_string_p from incorrect
2420 detection of uninitialized objects from spare memory as live.
2422 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
2425 * Makefile.in (.PHONY): versioclean -> versionclean.
2427 Remove unused external symbols.
2428 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
2429 * window.c (Qwindow_valid_p, decode_valid_window):
2430 Now static, not extern.
2431 * data.c (Qinterval): Remove; unused.
2432 (syms_of_data): Do not define 'interval'.
2433 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
2434 * window.h (decode_valid_window):
2437 * character.c, charset.c, chartab.c: Use bool for booleans.

2447 (char_table_set_range, optimize_sub_char_table)
2448 (map_sub_char_table):
2449 Use bool for boolean.
2450 * character.c (str_to_unibyte): Omit last boolean argument; it was
2451 always 0. All callers changed.
2452 * character.h, charset.h: Adjust to match previous changes.
2453 * character.h (char_printable_p): Remove decl of nonexistent function.
2454 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
2455 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
2456 are all boolean, so make them single-bit bitfields.
2458 * lisp.h (ASET): Remove attempt to detect side effects.
2459 It was meant to be temporary and it often doesn't work,
2460 because when IDX has side effects the behavior of IDX==IDX
2461 is undefined. See Stefan Monnier in
2462 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
2464 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
2466 * lisp.h (functionp): New function (extracted from Ffunctionp).
2467 (FUNCTIONP): Use it.
2468 * eval.c (Ffunctionp): Use it.
2470 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
2472 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
2473 as that's faster and simpler than static storage. Don't bother
2474 with the g_main_context_query overhead if g_main_context_pending
2475 says no events are pending.
2476 (gfds, gfds_size): Remove these static vars.
2477 (xgselect_initialize): Remove; no longer needed.
2478 All uses and decls removed.
2480 * emacs.c (fatal_error_signal_hook): Remove.
2481 All uses removed. This leftover from old code was always 0.
2483 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
2484 * casefiddle.c (casify_object, casify_region):
2485 * casetab.c (set_case_table):
2486 * category.c, category.h (word_boundary_p):
2487 * category.h (CHAR_HAS_CATEGORY):
2488 Use bool for booleans, instead of int.
2490 2012-08-25 Eli Zaretskii <eliz@gnu.org>
2492 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
2494 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
2496 On assertion failure, print backtrace if available.
2497 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
2498 (die) [ENABLE_CHECKING]: Print a backtrace if available.
2499 * Makefile.in (LIB_EXECINFO): New macro.
2502 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
2503 * bytecode.c (exec_byte_code):
2504 * callint.c (check_mark, Fcall_interactively):
2505 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
2506 (getenv_internal, sync_process_alive, call_process_exited):
2507 * lisp.h (USE_SAFE_ALLOCA):
2508 Use bool for booleans, instead of int.
2509 * lisp.h, process.h: Adjust prototypes to match above changes.
2510 * callint.c (Fcall_interactively): Don't assume the mark's
2511 offset fits in 'int'.
2513 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
2515 * buffer.c, buffer.h: Use bool for boolean.
2516 * buffer.c (reset_buffer_local_variables)
2517 (buffer_lisp_local_variables, Fset_buffer_modified_p)

2521 (report_overlay_modification, call_overlay_mod_hooks):
2522 (mmap_enlarge, mmap_set_vars):
2523 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
2524 Use bool for booleans, instead of int.
2525 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
2526 since the 1-or-0 return value is always ignored anyway.
2527 (mmap_initialized_p):
2528 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
2529 * buffer.h, lisp.h: Adjust prototypes to match above changes.
2531 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
2533 * bidi.c: Use bool for boolean.
2534 This is a bit more readable, and makes the text segment of bidi.o
2535 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
2536 Presumably it's faster too.
2537 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
2539 (bidi_cache_find_level_change, bidi_cache_iterator_state)
2540 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
2541 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
2542 (bidi_explicit_dir_char, bidi_level_of_next_char)
2543 (bidi_find_other_level_edge, bidi_move_to_visually_next):
2544 Use bool for booleans, instead of int.
2545 * dispextern.h (bidi_init_it, bidi_paragraph_init)
2546 (bidi_unshelve_cache): Adjust decls to match code.
2548 2012-08-23 Martin Rudalics <rudalics@gmx.at>
2550 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
2553 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
2555 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
2556 * atimer.h: Include <stdbool.h>.
2558 2012-08-22 Dan Nicolaescu <dann@gnu.org>
2560 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
2561 compile time tests instead of run time tests on systems that do
2563 (FRAME_MAC_P): Remove leftover from deleted code.
2564 * frame.c (syms_of_frame): Remove leftover from deleted code.
2566 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
2568 * nsterm.m (insertText:): Don't clear modifiers if code is space.
2570 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
2572 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
2573 Otherwise, the compiler complains about (A?B:C) where B is void
2574 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
2575 (fontset_add): Return void, for FONTSET_ADD.
2577 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2579 * alloc.c: Use bool for booleans.
2580 (gc_in_progress, abort_on_gc)
2581 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
2582 (dont_register_blocks) [GC_MALLOC_CHECK]:
2583 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
2584 (check_string_bytes, make_specified_string, memory_full)
2585 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
2586 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
2587 (mark_stack, valid_pointer_p, make_pure_string)
2588 (Fgarbage_collect, survives_gc_p, gc_sweep):
2589 Use bool for booleans, instead of int.
2590 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
2591 Remove unused local.
2592 * alloc.c (PURE_POINTER_P):
2593 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
2594 * editfns.c (Fformat):
2595 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
2597 * fns.c (sweep_weak_table):
2598 * lisp.h (suppress_checking, push_message, survives_gc_p)
2599 (make_pure_string, gc_in_progress, abort_on_gc):
2600 * lread.c (readchar, read1):
2601 * print.c (Fprin1_to_string):
2602 * xdisp.c (push_message):
2603 Use bool for booleans affected directly or indirectly by
2606 Make recently-introduced setters macros.
2607 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
2608 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
2609 (set_fontset_default, set_fontset_fallback): Rename from their
2610 upper-case counterparts, and make them functions rather than macros.
2611 This is more consistent with the other recently-introduced setters.
2612 These don't need to be inline, since they're local.
2614 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
2616 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
2617 the loop (Bug#12247).
2619 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2621 * lisp.h (vcopy): Use memcpy rather than our own loop.
2622 This fixes a performance regression introduced by the recent
2623 addition of vcopy. This means 'vcopy' will need to be modified
2624 for a copying collector, but that's OK. Also, tighten the
2625 checking in the assertion.
2627 2012-08-21 Eli Zaretskii <eliz@gnu.org>
2629 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
2630 components for RTL text (Bug#11860). Adjust X-OFFSET of each
2631 non-base glyph for the width of the base character, according to
2632 what x_draw_composite_glyph_string_foreground expects.
2633 Generate WADJUST value according to composition_gstring_width's
2634 expectations, to produce correct width of the composed character.
2635 Reverse the sign of the DU offset produced by ScriptPlace.
2637 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2639 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
2641 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2643 Avoid direct writes to contents member of struct Lisp_Vector.
2644 * lisp.h (vcopy): New function to copy data into vector.
2645 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
2646 * fns.c (Ffillarray): Use ASET.
2647 * keyboard.c (timer_check_2): Use AREF and ASET.
2648 (append_tool_bar_item, Frecent_keys): Use vcopy.
2649 * lread.c (read_vector): Use ASET.
2650 * msdos.c (Frecent_doskeys): Use vcopy.
2651 * xface.c (Finternal_copy_lisp_face): Use vcopy.
2652 (Finternal_merge_in_global_face): Use ASET and vcopy.
2653 * xfont.c (xfont_list_pattern): Likewise.
2655 2012-08-21 Martin Rudalics <rudalics@gmx.at>
2657 * window.c (Fwindow_point): For the selected window always return
2658 the position of its buffer's point.
2659 (Fset_window_point): For the selected window always go in its
2660 buffer to the specified position.
2662 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2664 Setter macros for fontsets.
2665 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
2666 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
2667 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
2670 2012-08-20 Glenn Morris <rgm@gnu.org>
2672 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
2673 Don't assume that `ln -f' works.
2675 2012-08-20 Eli Zaretskii <eliz@gnu.org>
2677 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
2678 and later about non-assignments with no effect. See discussion at
2679 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
2682 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2684 Inline setter functions for Lisp_Objects slots of struct specbinding.
2685 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
2688 2012-08-20 Martin Rudalics <rudalics@gmx.at>
2690 * window.c (select_window): Always make selected window's buffer
2693 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2695 Use AREF and ASET for docstrings of category tables.
2696 * category.h (CATEGORY_DOCSTRING): Use AREF.
2697 (SET_CATEGORY_DOCSTRING): Use ASET.
2698 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
2700 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2702 Inline setter functions for hash table members.
2703 * lisp.h (set_hash_key, set_hash_value, set_hash_next)

2721 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
2723 Rely on <config.h> + <unistd.h> to declare 'environ',
2724 as gnulib does this if the system doesn't.
2725 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
2726 Remove declaration. MS-Windows declares it on stdlib.h which is

2729 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.

3594 2012-08-04 Eli Zaretskii <eliz@gnu.org>
3596 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
3597 * w32.c (init_environment): Change the default values of many
3598 environment variables in dflt_envvars[] to NULL, to avoid pushing
3599 them into environment when they were not already defined.
3600 Remove the code that deletes site-lisp subdirectories from the default
3601 value of EMACSLOADPATH, as it is no longer needed.
3602 (check_windows_init_file): Now external, not static.
3603 Use Vload_path as is, without adding anything, as this function is now
3604 called when Vload_path is already set up.
3606 * w32.h (check_windows_init_file): Add prototype.
3608 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
3609 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
3610 compatibility with Posix platforms.
3611 (main): Move the call to check_windows_init_file to here from
3613 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
3614 any, in the DEFALT argument into the root of the Emacs build or
3615 installation tree, as appropriate.
3617 * callproc.c (init_callproc_1): Call decode_env_path instead of
3618 doing its equivalent by hand.
3619 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
3620 the code that sets Vexec_path run on MS-Windows.
3622 * lread.c (init_lread): Add comments to #ifdef's.
3624 * msdos.c (dos_set_window_size, IT_update_begin)
3625 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
3626 instead of direct references.
3628 2012-08-04 Paul Eggert <eggert@cs.ucla.edu>
3630 Export DEFAULT_REHASH_* to GDB.
3631 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
3632 Now constants, not macros.
3634 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
3636 Remove unnecessary casts involving pointers.
3637 These casts are no longer needed now that we assume C89 or later,
3638 since they involve casting to or from void *.
3639 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
3640 (make_pure_float, make_pure_vector):
3641 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

3651 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
3652 Remove unnecessary pointer casts.
3653 * alloc.c (record_xmalloc): New function.
3654 * lisp.h (record_xmalloc): New decl.
3655 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
3656 more like a function. This is because the pointer cast is not
3657 needed. All uses changed.
3658 * print.c (print_string, print_error_message): Avoid length recalc.
3660 Improve fix for macroexp crash with debugging (Bug#12118).
3661 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
3662 ARRAY_MARK_FLAG when checking subscripts, because ASET is
3663 not supposed to be invoked from the garbage collector.
3664 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
3665 (gc_aset): New function, which is like ASET but can be
3666 used in the garbage collector.
3667 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

3677 <g_b_init_create_symbolic_link>: New static flags.
3678 (globals_of_w32): Initialize them to zero.
3679 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
3680 (map_w32_filename): Improve commentary. Simplify switch.
3681 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
3682 headers (most versions of MinGW w32api don't).
3683 (get_security_info, create_symbolic_link)
3684 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
3686 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
3687 in the argument file name.
3688 (sys_access): Call unc_volume_file_attributes only if

3690 (sys_rename): Diagnose renaming of a symlink when the user doesn't
3691 have the required privileges.
3692 (get_file_security_desc_by_name): Rename from
3693 get_file_security_desc.
3694 (stat_worker): New function, with most of the guts of 'stat', and
3695 with addition of handling of symlinks and support for 'lstat'.
3696 If possible, get file's attributes and security information by
3697 handle, not by name. Produce S_IFLNK bit for symlinks, when
3698 called from 'lstat'.
3699 (stat, lstat): New functions, call 'stat_worker'.
3700 (symlink, readlink, careadlinkat): Rewritten to create and resolve
3701 symlinks when the underlying filesystem supports them.
3703 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
3705 Fix macroexp crash on Windows with debugging (Bug#12118).
3706 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
3707 checking subscripts; problem introduced with the recent
3708 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
3709 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
3710 since it's used in non-static inline functions now.
3712 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
3713 Don't assume buffer size fits in 'int'. Remove unused local.
3715 Use C99-style 'extern inline' if available.

3727 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
3728 * alloc.c (LISP_INLINE):
3729 * buffer.c (BUFFER_INLINE):
3730 * category.c (CATEGORY_INLINE):
3731 * character.c (CHARACTER_INLINE):
3732 * charset.c (CHARSET_INLINE):
3733 * composite.c (COMPOSITE_INLINE):
3734 * dispnew.c (DISPEXTERN_INLINE):
3735 * sysdep.c (SYSTIME_INLINE):
3736 Define to EXTERN_INLINE, so that the corresponding functions
3737 are compiled into code.
3738 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
3739 (INLINE_HEADER_END): New macros.
3740 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

3760 hard-coding the path separator.
3762 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
3764 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
3765 This how ASET and AREF are supposed to work, and makes
3766 it easier to think about future improvements. See
3767 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
3768 * charset.h (set_charset_attr): New function.
3769 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
3770 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

4145 * w32inevt.c: Include w32inevt.h.
4146 (w32_read_console_input): New inline function, calls either

4148 w32_console_unicode_input.
4149 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
4150 (w32_kbd_patch_key, key_event): Use the codepage returned by
4151 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

4183 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
4184 enumeration constants, as PURE and HEAP are too general, and clash
4185 with other headers and sources, such as gmalloc.c and the
4186 MS-Windows system headers. All users changed.
4188 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
4190 Revert last save_excursion_save and save_excursion_restore changes.
4191 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

4204 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
4205 arms of an 'if', not using conditional expressions; otherwise GDB
4206 complains about the types in the unevaluated arm when the argument
4207 is an integer literal.
4208 (xgetint): Simplify expression.
4209 * alloc.c (gdb_make_enums_visible): New constant. This ports to
4210 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
4211 Zaretskii in <http://bugs.gnu.org/12036#13>.
4212 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
4213 needed now that we have gdb_make_enums_visible.
4214 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
4215 (enum enum_USE_LSB_TAG):
4216 New enum types, packaging up enums that need to be exported to GDB.

4240 * lisp.h (struct Lisp_Excursion): New data type.
4241 (PVEC_EXCURSION): New pseudovector type.

4258 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
4259 emacs.c, as this is a more-suitable home. Had this been done earlier
4260 the fix for 12036 would have avoided some of the problems noted in
4261 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
4262 would have been more obvious.
4263 * emacs.c: Do not include <verify.h>; no longer needed.
4264 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
4265 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
4266 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

4271 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
4272 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
4273 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
4274 not be usable in #if. This simplifies things.
4276 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
4278 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

4283 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
4284 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
4285 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
4286 Adjust to changes in lisp.h and emacs.c, by using
4287 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
4288 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
4289 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
4290 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
4291 instead of gdb_valbits.
4292 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
4293 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
4294 instead of gdb_array_mark_flag.
4295 (xboolvector): Get size from $->size, not $->header.size.
4296 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
4297 (xreload, hook-run, hookpost-run): Remove.
4298 * emacs.c: Include <verify.h>.
4299 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
4300 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
4302 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
4303 (gdb_USE_LSB_TAG): New enum constants.
4304 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
4305 Also define these as enum constants, so they're visible to GDB.
4306 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
4307 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
4308 as constants, so they're visible to GDB.

4310 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
4311 Now enum constants, not macros, so they're visible to GDB.
4312 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
4313 more convenient now. All uses changed.
4314 (VALMASK) [USE_LSB_TAG]: Also define in this case.
4315 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
4317 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

4322 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
4324 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
4325 add argument, tune behavior, and adjust all callers.
4327 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
4329 Use typedef for EMACS_INT, EMACS_UINT.
4330 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
4331 than macros. This simplifies debugging in the usual case, since
4332 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
4333 and it allows expressions involving EMACS_INT casts.
4334 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
4336 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

4346 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
4348 Adjust buffer text indirection counters at the end of Fkill_buffer.
4349 * buffer.c (Fkill_buffer): Adjust indirection counters when the
4350 buffer is definitely dead. This should really fix an issue reported
4351 by Christoph Scholtes again. (Bug#12007).
4352 (init_buffer_once): Initialize indirection counters of
4353 buffer_defaults and buffer_local_symbols (for sanity and safety).
4355 2012-07-24 Eli Zaretskii <eliz@gnu.org>
4357 * xdisp.c (init_iterator): Don't compute dimensions of truncation
4358 and continuation glyphs on tooltip frames, leave them at zero.

4361 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
4363 Simplify copy_overlay.
4364 * buffer.c (copy_overlay): Simplify. Use build_marker.

4373 it signals an error when a tooltip frame is being created.
4375 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
4377 Cleanup miscellaneous objects allocation and initialization.

4384 (build_overlay): Add prototype.
4386 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
4388 Swap buffer text indirection counters in Fbuffer_swap_text.
4389 * buffer.c (Fbuffer_swap_text): Swap indirections too.
4390 This avoids crash reported by Christoph Scholtes at
4391 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
4393 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
4395 * nsmenu.m (Popdown_data): New struct.
4396 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
4398 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
4399 (initWithContentRect): Make imgView and contentView non-static
4400 and autorelease them. Also autorelease img and matrix (Bug#12005).
4401 (dealloc): Remove (Bug#12005).
4403 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
4405 Adjust consing_since_gc when objects are explicitly freed.
4406 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
4407 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.
4408 (free_cons, free_misc): Subtract object size from consing_since_gc.
4410 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>

4418 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
4420 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
4421 as it's limited by the amount of memory, not by INT_MAX.
4423 2012-07-21 Eli Zaretskii <eliz@gnu.org>
4425 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
4426 in special-event-map. See the discussion at

5149 * s/aix4-2.h (unix): Remove; no longer needed.
5151 EMACS_TIME simplification (Bug#11875).
5152 This replaces macros (which typically do not work in GDB)

5154 The functional style also makes code easier to read and maintain.
5155 * systime.h: Include <sys/time.h> on all hosts, not just if
5156 WINDOWSNT, since 'struct timeval' is needed in general.

5172 (add_emacs_time, sub_emacs_time): New functions.
5173 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

5196 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
5197 Prefer snprintf to strncpy.
5198 * nsterm.m (ns_term_init):
5199 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
5200 * nsterm.m (ns_term_init):
5201 Avoid the need for strncpy, by using build_string or
5202 make_unibyte_string directly. Use dtoastr, not snprintf.
5203 * process.c (Fmake_network_process): Diagnose service names that
5204 are too long, rather than silently truncating them or creating
5205 non-null-terminated names.
5206 (Fnetwork_interface_info): Likewise, for interface names.
5207 * sysdep.c (system_process_attributes) [GNU_LINUX]:
5208 Prefer sprintf to strncat.

5222 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
5223 where argument type is known to be a Lisp_Cons.

5278 O_RDONLY already includes it).
5280 Stop ns builds setting the EMACSLOADPATH environment variable.
5281 * nsterm.m (ns_load_path): Rename from ns_init_paths.
5282 Now it does not set EMACSLOADPATH, just returns the load-path string.

5284 * lread.c [HAVE_NS]: Include nsterm.h.
5285 (init_lread) [HAVE_NS]: Use ns_load_path.

5295 (ns_init_paths): Do not set EMACSPATH.

5350 * callproc.c [HAVE_NS]: Include nsterm.h.
5351 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
5353 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
5355 Move marker debugging code under MARKER_DEBUG.
5356 * marker.c (MARKER_DEBUG): Move marker debugging code under
5357 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
5358 for bootstrap with --enable-checking (~3x slowdown reported
5359 by Juanma Barranquero <lekktu@gmail.com>).
5360 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
5362 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
5364 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
5365 See <http://bugs.gnu.org/11825#29>.
5367 2012-07-08 Eli Zaretskii <eliz@gnu.org>
5369 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
5370 has no font, use the frame's font. (Bug#11813)
5371 (display_line): Add commentary about displaying truncation glyphs
5373 (produce_special_glyphs): Move here from term.c.
5375 * term.c (produce_special_glyphs): Move to xdisp.c.
5377 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
5380 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
5382 * xdisp.c (display_line): Avoid warning about implicit declaration
5385 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
5387 * lisp.h: Remove empty conditional.
5389 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
5391 * lread.c (load_path_check): Now static.
5393 Fix some minor --with-ns problems found by static checking.
5394 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
5395 (x_set_font) [!HAVE_X_WINDOWS]:
5396 * image.c (xpm_load_image) [HAVE_NS]:
5397 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
5398 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
5399 Remove unused local.
5400 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
5401 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
5402 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
5403 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
5404 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
5405 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
5406 Fix pointer signedness problem.
5407 * xfaces.c (FRAME_X_FONT_TABLE):
5408 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
5410 2012-07-07 Glenn Morris <rgm@gnu.org>
5412 * lread.c (load_path_check): New function, split from init_lread.
5413 (init_lread): Reorganize. Motivation:
5414 If EMACSLOADPATH is set, check/warn about that rather than the
5415 defaults, which we are not going to use. Hence we can remove
5416 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
5417 Don't warn if site-lisp directories are missing.
5418 If not installed, start from a blank load-path, since
5419 PATH_LOADSEARCH refers to the eventual installation directories.
5421 2012-07-07 Eli Zaretskii <eliz@gnu.org>
5423 Support truncation and continuation glyphs on GUI frames, when
5424 fringes are disabled. (Bug#11832)
5425 * xdisp.c (init_iterator): Get dimensions of truncation and
5426 continuation glyphs even if on GUI frames.
5427 Adjust it->last_visible_x on GUI frames when the left or right fringes,
5428 or both, are absent.
5429 (start_display, move_it_in_display_line_to): Handle the case of a
5430 GUI frame without a fringe to display continuation or truncation
5432 (insert_left_trunc_glyphs): Support GUI frames: make sure
5433 truncation glyphs overwrite enough glyphs from the current line to
5434 have sufficient space in pixels.
5435 (display_line): Support truncation and continuation glyphs on GUI
5436 frames. If some spare pixels are left on the line after inserting
5437 the truncation glyphs, fill that space with a stretch glyph of a
5438 suitably computed width.
5440 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
5441 produce_glyphs, to support GUI sessions.
5443 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
5445 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
5447 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
5449 Do not require float-time's arg to fit in time_t (Bug#11825).
5450 This works better on hosts where time_t is unsigned, and where
5451 float-time is applied to the (negative) difference between two times.
5452 * editfns.c (decode_time_components): Last arg is now double *,
5453 not int *, and means to store all the result as a double, without
5454 worrying about whether the seconds part fits in time_t.
5455 All callers changed.
5456 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
5457 All callers changed.
5458 (Ffloat_time): Do not fail merely because the specified time falls
5459 outside of time_t range.
5461 2012-07-07 Glenn Morris <rgm@gnu.org>
5463 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
5464 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

5467 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
5469 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
5470 Update dependencies.
5472 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
5474 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5476 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
5477 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
5478 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
5479 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
5480 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
5481 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
5483 * xfont.c (compare_font_names): Redo to omit the need for casts.
5485 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
5487 * xfns.c (Fx_change_window_property): Doc fix.
5488 * w32fns.c (Fx_change_window_property): Doc fix.
5490 * w32fns.c (Fx_window_property): Accept the same arguments as the
5491 X Windows version. Doc fix.
5492 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
5494 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
5495 Eli Zaretskii <eliz@gnu.org>
5497 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
5498 Windows-specific code from nt/config.nt moved here.
5499 Obsolete settings removed.
5501 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5503 * process.c: Avoid unnecessary calls to gettime.
5504 (wait_reading_process_output): Don't get the time of day
5505 when gobbling data immediately and not waiting, as there's no need
5506 for it in that case. This removes a FIXME.
5508 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
5510 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
5511 is defined (Bug#11768).
5513 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5515 Fix marker debugging code.
5516 * marker.c (byte_char_debug_check): Do not perform the check
5517 if buffer is not multibyte.
5518 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
5519 Call byte_char_debug_check with correct arguments.
5521 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5523 Compile marker debugging code only if ENABLE_CHECKING is defined.
5524 * marker.c (byte_char_debug_check, count_markers):
5525 Use only if ENABLE_CHECKING is defined.
5526 (byte_debug_flag): Remove.
5527 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
5528 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
5530 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5532 Avoid code repetition in marker-related functions.
5533 * marker.c (attach_marker): New function.
5534 (Fset_marker, set_marker_restricted, set_marker_both)
5535 (set_marker_restricted_both): Use it.
5536 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
5537 Consistently rename charno to charpos.
5538 (marker_position): Add eassert.
5539 (marker_byte_position): Convert to eassert.
5541 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5543 Simplify list operations in unchain_overlay and unchain_marker.

5547 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5549 Introduce fast path for the widely used marker operation.
5550 * alloc.c (build_marker): New function.
5551 * lisp.h (build_marker): New prototype.
5552 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
5553 * composite.c (autocmp_chars): Likewise.
5554 * editfns.c (buildmark): Remove.
5555 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
5556 (save_restriction_save): Use build_marker.
5557 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
5558 * window.c (save_window_save): Likewise.
5560 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5562 Do not use Fdelete_overlay in delete_all_overlays
5563 to avoid redundant calls to unchain_overlay.
5564 * buffer.c (drop_overlay): New function.
5565 (delete_all_overlays, Fdelete_overlay): Use it.
5566 * minibuf.c (get_minibuffer): Fix comment.
5568 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5570 Port to OpenBSD 5.1 amd64.
5571 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
5572 This is needed for OpenBSD, and should be harmless on all BSD systems.
5573 Also, include <sys/sysctl.h>, as it should be available on all
5574 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
5575 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
5576 use p_pid member, not kp_proc.pid.
5578 2012-07-06 Glenn Morris <rgm@gnu.org>
5580 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
5582 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5584 More xmalloc and related cleanup.
5585 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
5586 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
5587 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

5590 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
5591 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
5592 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
5593 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
5595 Omit needless casts involving void * pointers and allocation.
5596 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
5597 as the former is more robust if P's type is changed.
5598 Prefer xzalloc to xmalloc + memset 0.
5599 Simplify malloc-or-realloc to realloc.
5600 Don't worry about xmalloc returning a null pointer.
5601 Prefer xstrdup to xmalloc + strcpy.
5602 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
5604 * keyboard.c (apply_modifiers_uncached): Prefer local array to
5605 alloca of a constant.
5607 2012-07-05 Eli Zaretskii <eliz@gnu.org>
5609 * xdisp.c (display_line): Fix horizontal pixel coordinates when
5610 hscroll is larger than the line width. Fixes long and futile
5611 looping inside extend_face_to_end_of_line (on a TTY) producing
5612 glyphs that are not needed and thrown away.
5614 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
5616 * marker.c (set_marker_restricted_both): Simplify by using
5619 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5621 * editfns.c (region_limit): Simplify by using clip_to_bounds.
5623 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>

5628 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
5629 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
5630 followed by gtk_box_set_homogeneous (Bug#11768).
5631 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
5632 (update_theme_scrollbar_width, xg_create_scroll_bar):
5633 Use gtk_scrollbar_new (Bug#11768).
5634 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
5635 (is_box_type): New function (Bug#11768).
5636 (xg_tool_item_stale_p): Call is_box_type.
5637 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
5638 with default display (Bug#11768).
5640 2012-07-05 Eli Zaretskii <eliz@gnu.org>
5642 * xdisp.c (window_hscroll_limited): New function.
5643 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
5644 coordinates when window's hscroll is set to insanely large
5647 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
5649 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
5650 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
5652 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
5655 * lisp.h (xzalloc): New prototype. Omit needless casts.
5656 * alloc.c (xzalloc): New function. Omit needless casts.
5657 * charset.c: Omit needless casts. Convert all calls to
5658 xmalloc with following memset to xzalloc.
5659 * dispnew.c: Likewise.

5708 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5710 * fileio.c (time_error_value): Check the right error number.
5711 Problem reported by Troels Nielsen in
5712 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
5714 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5716 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
5717 This should be fixed in a better way; see Eli Zaretskii in
5718 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
5719 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
5721 * fileio.c (time_error_value): Rename from special_mtime.
5722 The old name's problems were noted by Eli Zaretskii in
5723 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
5725 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
5726 This variable's comment says Emacs needs at least one GDB-visible
5727 symbol of type enum pvec_type, to work around GDB problems.
5728 The symbol's value doesn't matter.
5730 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
5731 that causes compilation to fail on pre-C99 compilers.
5733 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
5735 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
5736 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
5738 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5740 * buffer.c (init_buffer_once): Fix initialization of
5741 headers for buffer_defaults and buffer_local_symbols.
5742 Reported by Juanma Barranquero <lekktu@gmail.com>.
5744 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
5746 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
5747 * lisp.h (enum pvec_type): Use fewer bits.
5748 (PSEUDOVECTOR_SIZE_BITS): New constant.
5749 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
5750 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
5751 change in pvec_type.
5752 (PSEUDOVECTOR_TYPEP): New macro.
5753 (TYPED_PSEUDOVECTORP): Use it.
5754 * fns.c (internal_equal): Adapt code to extract pvectype.
5755 * emacs.c (gdb_pvec_type): Update type.
5756 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
5757 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
5758 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
5759 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
5760 (sweep_vectors): Use it. Use local var `total_bytes' instead of
5761 abusing vector->header.next.nbytes.
5762 (live_vector_p): Use PVEC_TYPE.
5763 (mark_object): Adapt code to extract pvectype. Use switch.
5765 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5767 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
5768 Tighten new eassert a bit.
5770 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5772 Fix compilation with --enable-gcc-warnings and -O1
5774 * doprnt.c (doprnt): Change type of tem to int, initialize
5775 to avoid compiler warning. Add eassert.
5776 * search.c (simple_search): Initialize match_byte to avoid
5777 compiler warning. Add eassert.
5779 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5781 Avoid weird behavior with large horizontal scrolls.
5782 Without this change, for example, large hscroll values would
5783 mess up Emacs's display on Fedora 15 x86, presumably due to
5784 overflows in int calculations in the display code.
5785 Also, if buffers had long lines, Emacs would freeze.
5786 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
5787 (set_window_hscroll): New function, containing the old guts of
5788 Fset_window_hscroll. Return the clipped value.
5789 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
5790 This avoids the need to check against PTRDIFF_MAX.
5792 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
5794 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5796 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
5798 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5800 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
5801 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
5802 since GCC 4.4.6 issues a bogus warning for them.
5804 Fix bugs in file timestamp newness comparisons.
5805 * fileio.c (Ffile_newer_than_file_p):
5806 * lread.c (Fload): Use full timestamp resolution of files,
5807 not just the 1-second resolution, so that files that are only
5808 slightly newer still count as newer.
5809 * fileio.c (Ffile_newer_than_file_p): Don't assume file
5810 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
5812 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
5814 * fileio.c: Improve handling of file time marker. (Bug#11852)
5815 (special_mtime): New function.
5816 (Finsert_file_contents, Fverify_visited_file_modtime):
5817 Use it to set special mtime values consistently.
5819 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
5821 * fileio.c (Finsert_file_contents): Properly handle st_mtime
5822 marker for non-existing file. (Bug#11852)
5824 2012-07-03 Glenn Morris <rgm@gnu.org>
5826 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
5827 and did not make it into globals.h).
5829 2012-07-03 Tom Tromey <tromey@redhat.com>
5831 * window.c (Fset_window_margins, Fset_window_fringes)
5832 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.

5875 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
5876 values which aren't power of 2.
5877 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
5878 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
5881 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
5883 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
5885 * alloc.c (mark_object): Revert part of last patch to use `switch'.
5887 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5889 * alloc.c (allocate_vector_block): Remove redundant
5890 calls to mallopt if DOUG_LEA_MALLOC is defined.
5891 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
5892 avoid calls to mallopt if zero_vector is returned.
5894 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5896 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
5897 is enabled, avoid dereferencing NULL current_sblock if
5900 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5902 Cleanup basic buffer management.
5903 * buffer.h (struct buffer): Change layout to use generic vector
5904 marking code. Fix some comments. Change type of 'clip_changed'
5905 to bitfield. Remove unused #ifndef old.
5906 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
5907 (GET_OVERLAYS_AT): Fix indentation.
5908 (for_each_per_buffer_object_at): New macro.
5909 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
5910 (Fbuffer_local_variables): Use it.
5911 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
5912 * alloc.c (allocate_buffer): Adjust to match new layout of
5913 struct buffer. Fix comment.
5914 (mark_overlay): New function.
5915 (mark_buffer): Use it. Use mark_vectorlike to mark normal
5916 Lisp area of struct buffer.
5917 (mark_object): Use it. Adjust marking of misc objects
5918 and related comments.
5920 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
5922 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
5923 wrapper that is not needed because the wrapped code is a no-op (zero
5924 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
5925 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
5927 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
5929 * alloc.c (mark_buffer): Simplify. Remove prototype.
5930 (mark_object): Add comment. Reorganize marking of vector-like
5931 objects. Use CHECK_LIVE for all vector-like objects except buffers
5932 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
5933 Avoid redundant calls to mark_vectorlike for bool vectors.
5935 2012-06-30 Glenn Morris <rgm@gnu.org>
5937 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
5939 * epaths.in (PATH_SITELOADSEARCH): New.
5940 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
5941 This is rather than relying on --enable-locallisppath elements
5942 having "site-lisp" in their names. (Bug#10208#25, 11658)
5944 2012-06-30 Eli Zaretskii <eliz@gnu.org>
5946 * w32proc.c (sys_select): Accept and ignore one more argument.
5948 * w32.c (emacs_gnutls_pull): Call select with one more argument.
5950 * sysselect.h [DOS_NT]: Don't include sys/select.h.
5951 (pselect) [!MS_DOS]: Redirect to sys_select.
5953 * sysdep.c: Don't include dos.h and dosfns.h.
5955 * process.c (sys_select):
5956 * msdos.c (sys_select): Accept one more argument and ignore it.
5958 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
5959 adapt data types and code to that.
5962 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
5963 which clashes with the gnulib function of the same name.
5965 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
5967 * font.c (font_style_to_value, font_style_symbolic)
5968 (font_prop_validate_style): Add type checks for values in
5971 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
5973 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
5976 2012-06-29 Eli Zaretskii <eliz@gnu.org>
5978 * xdisp.c (try_window_id): Undo last change.
5980 * w32.c (getwd): Adjust commentary about startup_dir.
5981 (init_environment): Always call sys_access, even in non-MSVC
5982 builds. Don't chdir to the directory of the Emacs executable.
5983 This undoes code from 1997 which was justified by the need to
5984 "avoid conflicts when removing and renaming directories". But its
5985 downside was that every relative file name was being interpreted
5986 relative to the directory of the Emacs executable, which can never
5987 be TRT. In particular, it broke sys_access when called with
5988 relative file names.
5989 (sys_access): Map GetLastError to errno.
5991 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5993 * window.h (struct window): Change type of 'fringes_outside_margins'

5997 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
6000 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

6003 Add QUIT to make the loop interruptible.
6005 2012-06-29 Glenn Morris <rgm@gnu.org>
6007 * charset.c (init_charset): Make lack of etc/charsets fatal.
6009 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6011 * editfns.c (region_limit): Fix type mismatch.
6013 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6015 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
6016 undefined. Convert from xassert to eassert.
6017 * nsmenu.m: Convert from xassert to eassert.
6018 * nsterm.m: Likewise.
6020 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
6022 * editfns.c (region_limit): Clip to narrowing (bug#11770).
6024 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
6026 Avoid integer overflow on scroll-left and scroll-right.
6027 * window.c (HSCROLL_MAX): New macro.
6028 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
6029 overflow when requested scroll falls outside ptrdiff_t range.

6033 * window.h (struct window): Change type of 'hscroll',
6034 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
6035 'last_modified' and 'last_overlay_modified' to EMACS_INT.
6036 Adjust users accordingly.
6037 * xdisp.c (try_cursor_movement): Replace type check with eassert.
6038 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
6039 from EMACS_INT to ptrdiff_t.
6040 (make_window): Omit redundant initialization.
6042 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

6046 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
6048 * window.h (struct window): Change type of 'use_time' and
6049 'sequence_number' from Lisp_Object to int.

6115 * alloc.c (allocate_string): Omit intervals initialization.
6116 * alloc.c (make_uninit_multibyte_string): Initialize intervals
6117 as in make_pure_string and make_pure_c_string.

6175 a better opportunity to optimize away calls to strlen when the
6176 function is called with compile-time constant argument.
6177 * image.c (imagemagick_error): Convert to build_string.
6178 * w32proc.c (sys_spawnve): Likewise.

6181 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
6183 Use sprintf return value instead of invoking strlen on result.
6184 In the old days this wasn't portable, since some sprintf
6185 implementations returned char *. But they died out years ago and
6186 Emacs already assumes sprintf returns int.
6187 Similarly for float_to_string.
6188 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
6189 * ccl.c (ccl_driver):
6190 * character.c (string_escape_byte8):

6193 * print.c (print_object):
6194 * xdisp.c (message_dolog):
6195 * xfns.c (syms_of_xfns):
6196 Use sprintf or float_to_string result to avoid need to call strlen.
6197 * data.c (Fnumber_to_string):
6198 Use make_unibyte_string, since the string must be ASCII.
6199 * lisp.h, print.c (float_to_string): Now returns int length.
6200 * term.c (produce_glyphless_glyph):
6201 Use sprintf result rather than recomputing it.
6203 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
6204 * Makefile.in (ALL_CFLAGS):
6205 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

6234 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
6236 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
6237 `const char *' to `char *' to avoid compiler warning.
6239 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
6241 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
6242 instead of truncating it to 63 (admittedly a generous limit).
6244 * process.c: Fix spelling and caps in comments.
6246 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
6248 * emacs.c (setpgrp): Remove definition, unused.

6295 Remove unnecessary forward decls.
6297 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
6299 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

6301 * dispnew.c (Fsleep_for, sit_for):
6302 * keyboard.c (kbd_buffer_get_event):
6303 * process.c (Faccept_process_output):

6305 This improves on the previous patch, which introduced a bug
6306 when time_t is unsigned and as wide as intmax_t.
6307 See <http://bugs.gnu.org/9000#51>.

6372 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
6374 Support higher-resolution time stamps (Bug#9000).
6375 The time stamps are only nanosecond-resolution at the C level,
6376 since that's the best that any real-world system supports now.
6377 But they are picosecond-resolution at the Lisp level, as that's
6378 easy, and leaves room for future OS improvements.
6380 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
6383 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
6384 Don't get current time unless it's needed.
6386 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
6387 now provides it if it's absent.
6388 (start_atimer): Port to higher-res time stamps.
6389 Check for time stamp overflow. Don't get current time more
6390 often than is needed.
6392 * buffer.h (struct buffer): Buffer modtime now has high resolution.
6393 Include systime.h, not time.h.
6394 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
6396 * dired.c: Include stat-time.h.
6397 (Ffile-attributes): File times now have higher resolution.
6399 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
6400 (struct image): Timestamp now has higher resolution.
6402 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
6403 has at least microseconds now. All uses removed.
6404 (update_frame, update_single_window, update_window, update_frame_1)
6405 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
6406 (duration_to_sec_usec): Remove; no longer needed.
6408 * editfns.c (time_overflow): Now extern.

6414 (decode_time_components, lisp_seconds_argument): New functions.
6415 (make_time): Now static.
6416 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
6417 Report an error if the time is invalid, rather than having the caller
6420 * fileio.c: Include <stat-time.h>
6421 (Fcopy_file): Copy higher-resolution time stamps.
6422 Prefer to set the time stamp via a file descriptor if that works.

6424 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
6425 (Fvisited_file_modtime, Fset_visited_file_modtime):
6426 Support higher-resolution time stamps.
6428 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
6430 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
6432 * image.c (prepare_image_for_display, clear_image_cache)
6433 (lookup_image): Port to higer-resolution time stamps.
6435 * keyboard.c (start_polling, bind_polling_period):
6436 Check for time stamp overflow.
6437 (read_char, kbd_buffer_get_event, timer_start_idle)
6438 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
6439 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
6440 Port to higher-resolution time stamps. Do not assume time_t is signed.
6441 (decode_timer): New function. Timers are now vectors of length 9,
6442 not 8, to accommodate the picosecond component.
6443 (timer_check_2): Use it.
6445 * nsterm.m (select_timeout, timeval_subtract): Remove.
6446 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
6447 as they're a bit more accurate and handle overflow better.
6448 (ns_select): Change prototype to be compatible with pselect.
6449 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
6450 * nsterm.h (ns_select): Adjust prototype.
6452 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
6453 us-resolution time stamps.
6454 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
6456 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
6458 * lisp.h (time_overflow): New decl.
6459 (wait_reading_process_output): First arg is now intmax_t, not int,
6460 to accommodate larger waits.
6462 * process.h (struct Lisp_Process.read_output_delay):
6463 Now counts nanoseconds, not microseconds.
6464 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
6466 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
6467 (wait_reading_process_output):

6469 (Faccept_process_output, wait_reading_process_output):
6470 Check for time stamp overflow. Do not assume time_t is signed.
6471 (select_wrapper): Remove; we now use pselect.
6472 (Fprocess_attributes): Now generates ns-resolution time stamps.
6474 * sysdep.c: Include utimens.h. Don't include utime.h
6475 or worry about struct utimbuf; gnulib does that for us now.
6476 (gettimeofday): Remove; gnulib provides a substitute.
6477 (make_timeval): New function.
6478 (set_file_times): Now sets ns-resolution time stamps.
6479 New arg FD; all uses changed.
6480 (time_from_jiffies, ltime_from_jiffies, get_up_time)
6481 (system_process_attributes):
6482 Now returns ns-resolution time stamp. All uses changed.
6483 Check for time stamp overflow.
6485 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
6486 provides a substitute now.
6488 * systime.h: Include timespec.h rather than sys/time.h and time.h,
6489 since it guarantees struct timespec.
6490 (EMACS_TIME): Now struct timespec, so that we can support
6491 ns-resolution time stamps.
6492 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
6493 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
6494 (EMACS_USECS): Remove.
6495 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
6496 so multiply the arg by 1000 before storing it.
6497 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
6499 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
6500 Port to ns-resolution time stamps.
6501 (EMACS_TIME_NEG_P): Remove; replaced by....
6502 (EMACS_TIME_SIGN): New macro.
6503 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
6504 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
6505 (set_file_times, make_time, lisp_time_argument): Adjust signature.
6506 (make_timeval, make_lisp_time, decode_time_components): New decls.
6507 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
6508 that it mishandled time_t overflow. You can't compare by subtracting!
6509 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
6510 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
6512 * term.c: Include <sys/time.h>.
6513 (timeval_to_Time): New function, for proper overflow wraparound.

6518 (Fprimitive_undo): Use them when restoring time stamps.
6520 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
6521 (w32_get_internal_run_time):
6522 Port to higher-resolution Emacs time stamps.
6523 (ltime): Now accepts single 64-bit integer, as that's more convenient
6526 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
6528 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
6529 for compatibility with pselect. Support ns-resolution time stamps.
6531 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
6533 * xselect.c (wait_for_property_change, x_get_foreign_selection):
6534 Check for time stamp overflow, and support ns-resolution time stamps.
6536 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
6537 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
6538 (timeval_subtract): Remove; no longer needed.
6539 (XTflash, XTring_bell, x_wait_for_event):
6540 Port to ns-resolution time stamps. Don't assume time_t is signed.
6542 2012-06-22 Chong Yidong <cyd@gnu.org>

6546 2012-06-22 Eli Zaretskii <eliz@gnu.org>
6548 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
6549 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
6550 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
6551 staticidx goes up to 1597 out of 1600 = 0x640.)
6553 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
6555 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
6556 Otherwise, the umask might be mistakenly 0 while handling input signals.

6590 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
6591 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
6592 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

6601 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
6602 gets killed during executing of this function (Bug#11665).
6603 Try to always return Qt when the buffer has been actually killed.
6604 (Vkill_buffer_query_functions): In doc-string say that functions
6605 run by this hook should not change the current buffer.
6607 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

6627 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
6629 * lisp.h (eassert): Assume C89 or later.
6630 This removes the need for CHECK.
6631 (CHECK): Remove. Its comments about always evaluating its
6632 argument were confusing, as 'eassert' typically does not evaluate
6635 * coding.c (produce_chars): Use ptrdiff_t, not int.
6637 * xterm.c (x_draw_underwave): Check for integer overflow.
6638 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

6790 * frame.c (delete_frame): Remove outdated comment.
6791 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
6792 USE_LISP_UNION_TYPE.

6794 (Fw32_toggle_lock_key): Likewise.
6795 * w32menu.c (add_menu_item): Likewise.
6796 (w32_menu_display_help): Use XIL instead of checking

6807 * s/gnu.h (POSIX_SIGNALS): Remove (not used since 2010-05-04).
6809 2012-06-13 Paul Eggert <eggert@cs.ucla.edu>
6811 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
6812 * alloc.c (make_number) [!defined make_number]:
6813 Remove, as lisp.h always defines this now.
6814 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
6815 (roundup_size): Verify that it is a power of 2.
6816 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
6817 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
6818 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
6819 -DUSE_LSB_TAG=0, to override the automatically-selected default.
6820 USE_LSB_TAG now is always defined to be either 0 or 1.
6822 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
6823 code works fine either way, and efficiency is not a concern here,
6824 as the union type is for debugging, not for production.
6825 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
6826 Use an inline function on all platforms when using the union type,
6827 since this is simpler and 'static inline' can be used portably
6829 (LISP_INITIALLY_ZERO): New macro.
6830 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
6831 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

6858 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
6859 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
6860 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.

6899 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
6900 dbus_type_is_basic if available.
6901 (xd_extract_signed, xd_extract_unsigned): Rename from
6902 extract_signed and extract_unsigned, respectively. Adapt callers.
6904 2012-06-09 Chong Yidong <cyd@gnu.org>
6906 * xfaces.c (face_for_overlay_string): Handle face remapping (Bug#2066).

6913 * xdisp.c (vmessage): Treat frame message as multibyte.
6914 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
6915 would generate the diagnostic "Making \302\247 buffer-local while
6918 2012-06-08 Eli Zaretskii <eliz@gnu.org>
6920 * dispnew.c (showing_window_margins_p): Undo last change, which

6933 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
6934 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
6936 2012-06-08 Eli Zaretskii <eliz@gnu.org>
6938 * alloc.c (allocate_vectorlike): Fix last change.
6940 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
6942 Block-based vector allocation of small vectors.
6943 * lisp.h (struct vectorlike_header): New field `nbytes',
6944 adjust comment accordingly.
6945 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
6946 to denote vector blocks. Adjust users (live_vector_p,
6947 mark_maybe_pointer, valid_lisp_object_p) accordingly.

6967 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
6969 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
6971 * doprnt.c (doprnt): Truncate multibyte char correctly.
6972 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
6973 would mishandle a string argument "Xc" if X was a multibyte
6974 character of length 2: it would truncate after X's first byte
6975 rather than including all of X.
6977 2012-06-06 Chong Yidong <cyd@gnu.org>
6979 * buffer.c (word_wrap): Doc fix.

7028 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
7029 Convert pctcpu and pctmem to Lisp float properly.
7030 Let the compiler fold better, as 100.0/0x8000 is exact.
7032 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
7034 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
7037 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
7039 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
7041 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
7043 For a 'struct window', replace some Lisp_Object fields to
7044 bitfields where appropriate, remove unused fields.
7045 * window.h (struct window): Remove unused 'last_mark_x' and
7046 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
7047 change it's type from Lisp_Object to bitfield.
7048 Change type of 'force_start', 'optional_new_start',
7049 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
7050 fields from Lisp_Object to bitfield. Adjust users accordingly.
7052 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
7054 Pacify gcc -Wdouble-precision when using Xaw.
7055 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
7056 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
7057 Use 'float' consistently, rather than 'float' in most places
7058 and 'double' in a couple of places.
7060 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7062 * xdisp.c (handle_stop): Detect whether we have overlay strings
7063 loaded by testing it->current.overlay_string_index to be
7064 non-negative, instead of checking whether n_overlay_strings is
7065 positive. (Bug#11587)
7067 2012-05-31 Chong Yidong <cyd@gnu.org>
7069 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
7071 * doc.c (Fsubstitute_command_keys): Doc fix.
7073 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7075 * search.c (search_buffer): Remove calls to
7076 r_alloc_inhibit_buffer_relocation, as it is now called by
7077 maybe_unify_char, which was the cause of relocation of buffer text
7080 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7082 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
7083 for the duration of call to load_charset, to avoid problems with
7084 callers of maybe_unify_char that access buffer text through C
7087 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
7088 decrement the inhibition flag, instead of just setting or
7091 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
7093 Remove obsolete '#define static' cruft.
7094 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
7095 This #undef was "temporary" in 2000; it is no longer needed
7096 now that '#define static' has gone away.
7097 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
7098 (gray_bitmap_bits): Remove; no longer needed.
7099 All uses replaced with definiens.
7100 * xterm.c: Include "bitmaps/gray.xbm".
7102 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
7104 Clean up __executable_start, monstartup when --enable-profiling.
7105 The following changes affect the code only when profiling.
7106 * dispnew.c (__executable_start): Rename from safe_bcopy.
7107 Define only on platforms that need it.
7108 * emacs.c: Include <sys/gmon.h> when profiling.
7109 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
7110 (__executable_start): Remove decl, since lisp.h does it now.
7111 (safe_bcopy): Remove decl; no longer has that name.
7112 (main): Coalesce #if into single bit of code, for simplicity.

7142 Do not create empty overlays with the evaporate property (Bug#9642).
7143 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
7144 Bug#9642, but explicitly check that the buffer the overlay would
7145 be moved to is live and rearrange lines to make sure that errors
7146 will not put the overlay in an inconsistent state.
7147 (Fdelete_overlay): Cosmetics.
7149 2012-05-28 Eli Zaretskii <eliz@gnu.org>
7151 * w32term.c (my_bring_window_to_top): New function.
7152 (x_raise_frame): Use handle returned by DeferWindowPos, which

7163 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
7165 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
7166 This avoids undefined behavior that might cause the eassert
7167 to not catch an out-of-range value.
7169 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
7171 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

7183 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
7185 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
7186 Only r_alloc_inhibit_buffer_relocation needed to be added;
7187 the others were already declared.
7189 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
7190 before checking whether it's out of range. Put the check inside
7192 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
7194 2012-05-27 Ken Brown <kbrown@cornell.edu>
7196 * callproc.c (Fcall_process): Restore a line that was accidentally
7197 commented out in the 2011-02-13 change (bug#11547).

7201 * lisp.h [REL_ALLOC]: Add prototypes for external functions
7202 defined on ralloc.c.
7204 * buffer.c [REL_ALLOC]: Remove prototypes of
7205 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
7206 they are now on lisp.h.
7208 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
7210 * search.c (search_buffer): Use it to inhibit relocation of buffer
7211 text while re_search_2 is doing its job, because re_search_2 is
7212 passed C pointers to buffer text. (Bug#11519)
7214 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
7217 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
7218 state after an additional call to move_it_in_display_line_to, keep
7219 the values of it->max_ascent and it->max_descent found for the
7221 (pos_visible_p): Revert the comparison against bottom_y to what it
7222 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
7225 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
7227 Fix coding-related core dumps with gcc -ftrapv.
7228 The code was computing A - B, where A and B are pointers, and B is
7229 random garbage. This can lead to core dumps on platforms that
7230 have special pointer registers, and it also leads to core dumps on
7231 x86-64 when compiled with gcc -ftrapv. The fix is to compute
7232 A - B only when B is initialized properly.
7233 * coding.c (coding_set_source, coding_set_destination): Return void.
7234 (coding_change_source, coding_change_destinations): New functions,
7235 with the old behaviors of coding_set_source and coding_set_destination.
7236 All callers that need an offset changed to use these new functions.
7238 2012-05-26 Glenn Morris <rgm@gnu.org>
7240 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
7242 2012-05-26 Eli Zaretskii <eliz@gnu.org>
7244 Extend mouse support on W32 text-mode console.
7245 * xdisp.c (draw_row_with_mouse_face):
7246 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
7248 * w32console.c: Include window.h.
7249 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
7251 (initialize_w32_display): Initialize mouse-highlight data.
7253 * w32inevt.c: Include termchar.h and window.h.
7254 (do_mouse_event): Support mouse-autoselect-window. When the mouse
7255 moves, call note_mouse_highlight. If help_echo changed, call
7256 gen_help_event to produce help-echo message in the echo area.

7263 with GCC 4.7.0 on x86-64.
7265 2012-05-26 Eli Zaretskii <eliz@gnu.org>
7267 * bidi.c (bidi_mirror_char): Revert last change: an int is
7268 definitely wide enough here.
7270 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
7272 Fix integer width and related bugs (Bug#9874).
7273 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):

7283 (allocate_pseudovector):
7284 Use int, not EMACS_INT, where int is wide enough.

7304 (Foverlay_recenter, last_overlay_modification_hooks_used)
7305 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
7306 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7307 (validate_region): Omit unnecessary test for b <= e,
7308 since that's guaranteed by the previous test.
7309 (adjust_overlays_for_delete): Avoid pos + length overflow.
7310 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
7311 (report_overlay_modification):
7312 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7313 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

7317 * buffer.h: Adjust decls to match defn changes elsewhere.

7322 not int, to avoid needless 32-bit limit on 64-bit hosts.
7323 (exec_byte_code): Use tighter memory-full test, one that checks
7324 for alloca overflow. Don't compute the address of the object just
7325 before an array, as that's not portable. Use EMACS_INT, not
7326 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
7327 * callint.c (Fcall_interactively):
7328 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

7339 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
7340 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7341 (casify_object): Avoid integer overflow when overallocating buffer.
7342 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
7343 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.

7345 * category.h (CATEGORYP): Don't assume arg is nonnegative.
7346 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
7347 integers are now checked earlier. All uses replaced with XINT.
7349 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7350 For CCL_MapSingle, check that content and value are in int range.
7351 (ccl_driver, Fregister_code_conversion_map):
7352 Check that Vcode_version_map_vector is a vector.
7353 (resolve_symbol_ccl_program): Check that vector header is in range.
7354 Always copy the vector, so that we can check its contents reliably
7355 now rather than having to recheck each instruction as it's being
7356 executed. Check that vector words fit in 'int'.
7357 (ccl_get_compiled_code, Fregister_ccl_program)
7358 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
7359 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
7360 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
7361 contents are in range.
7362 (Fccl_execute_on_string): Check that status is in range.
7363 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
7364 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
7365 Accept and return EMACS_INT, not int, because callers can pass values
7367 (c_string_width, strwidth, lisp_string_width, chars_in_text)
7368 (multibyte_chars_in_text, parse_str_as_multibyte)
7369 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)

7371 (string_escape_byte8, Fget_byte):
7372 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7373 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
7374 avoid mishandling large integers.
7375 * character.h: Adjust decls to match defn changes elsewhere.

7384 (Fdefine_charset_internal): Check ranges here, more carefully.
7385 Don't rely on undefined behavior with signed left shift overflow.
7386 Don't assume unsigned int fits into fixnum, or that fixnum fits
7387 into unsigned int. Don't require max_code to be a valid fixnum;
7388 that's not true for gb10830 4-byte on a 32-bit host. Allow
7389 invalid_code to be a cons, for the same reason. Require code_offset
7390 to be a character. Avoid int overflow if max_char is close
7392 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
7393 this is intended anyway and avoids some undefined behavior.
7394 (load_charset_map): Pass unsigned, not int, as 2nd arg of
7395 INDEX_TO_CODE_POINT, as that's what it expects.
7396 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
7397 * charset.h (DECODE_CHAR): Return int, not unsigned;
7398 this is what was intended anyway, and it avoids undefined behavior.
7399 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
7400 integer-overflow issues.
7401 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
7402 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
7403 where the argument is EMACS_INT, and this behavior is not intended.
7404 * chartab.c (Fmake_char_table, Fset_char_table_range)
7405 (uniprop_get_decoder, uniprop_get_encoder):
7406 Don't assume fixnum fits in int.
7407 * cmds.c (move_point): New function, that does the gist of
7408 Fforward_char and Fbackward_char, but does so while checking
7409 for integer overflow more accurately.
7410 (Fforward_char, Fbackward_char): Use it.
7411 (Fforward_line, Fend_of_line, internal_self_insert)
7412 (internal_self_insert):
7413 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7414 Fix a FIXME, by checking for integer overflow when calculating
7415 target_clm and actual_clm.

8072 2012-05-25 Glenn Morris <rgm@gnu.org>
8074 * lisp.mk (lisp): Update for more files being compiled now.
8076 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>

8096 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
8099 This directory predates autoconf and is no longer needed nowadays.
8100 Move its few remaining bits of functionality to where they're needed.

8110 (EMACS_UINT): Define unconditionally now.
8111 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
8112 (BITS_PER_EMACS_INT): New constants, replacing
8113 what used to be in config.h, but not useful in #if.
8114 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
8115 define them any more.
8116 (VAL_MAX): New macro.
8118 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
8119 BITS_PER_EMACS_INT, in #if.
8120 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
8121 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
8122 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
8123 * s/ms-w32.h (DATA_START):
8124 Move here from removed file m/intel386.h.
8125 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
8126 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
8128 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
8130 Assume C89 or later.
8131 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.

8140 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
8141 * xterm.c (input_signal_count): Assume volatile works.
8143 2012-05-21 Ken Brown <kbrown@cornell.edu>
8145 * xgselect.c (xg_select): Fix first argument in call to 'select'
8148 2012-05-20 Ken Brown <kbrown@cornell.edu>
8150 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
8151 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
8153 2012-05-19 Ken Brown <kbrown@cornell.edu>
8155 * xfns.c (x_in_use): Remove `static' qualifier.
8156 * xterm.h (x_in_use): Declare.
8157 * xgselect.c: Include xterm.h.

8163 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.

8166 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
8168 2012-05-18 Eli Zaretskii <eliz@gnu.org>
8170 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
8172 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
8173 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
8175 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
8176 reference to image_cache->refcount.
8177 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
8179 2012-05-17 Juri Linkov <juri@jurta.org>
8181 * search.c (Fword_search_regexp, Fword_search_backward)
8182 (Fword_search_forward, Fword_search_backward_lax)
8183 (Fword_search_forward_lax): Move functions to isearch.el
8184 (bug#10145, bug#11381).
8186 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
8188 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
8190 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
8192 * lread.c (init_obarray): Declare Qt and Qnil as special.
8194 2012-05-14 Glenn Morris <rgm@gnu.org>
8196 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
8197 Put "libexec" before "bin", for the sake of init_callproc_1.
8199 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
8201 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
8203 * unexaix.c: Port to more-recent AIX compilers.
8204 (report_error, report_error_1, make_hdr, copy_sym)
8205 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
8206 Make arguments const char *, not char *, to avoid violations of C
8207 standard and to fix some AIX warnings reported by Gilles Pion.
8209 2012-05-14 Eli Zaretskii <eliz@gnu.org>
8211 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
8212 already have overlays loaded.
8213 (handle_single_display_spec): Before returning without displaying
8214 fringe bitmap, synchronize the bidi iterator with the main display
8215 iterator, by calling iterate_out_of_display_property.
8216 (iterate_out_of_display_property): Detect buffer iteration by
8217 testing that it->string is a Lisp string.
8218 (get_next_display_element): When the current object is exhausted,
8219 and there's something on it->stack, call set_iterator_to_next to
8220 proceed with what's on the stack, instead of returning zero.
8221 (set_iterator_to_next): If called at the end of a Lisp string,
8222 proceed to consider_string_end without incrementing string
8223 position. Don't increment display vector index past the end of
8224 the display vector. (Bug#11417)
8225 (pos_visible_p): Don't report a position visible when move_it_to
8226 stopped at the last line of window, which happens to be scanned
8227 backwards by the bidi iteration. (Bug#11464)
8229 2012-05-14 Eli Zaretskii <eliz@gnu.org>
8231 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
8232 and right-margin display specs even if the spec is invalid or we
8233 are on a TTY, and thus unable to display on the fringes.
8234 That's because the text with the property will not be displayed anyway,
8235 so we need to signal to the caller that this is a "replacing"
8236 display spec. This fixes display when the spec is invalid or we
8239 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
8241 * unexaix.c (make_hdr): Fix typo in prototype.
8242 This bug broke the build on AIX. Problem reported by Gilles Pion.
8244 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
8246 * keyboard.c (kbd_buffer_get_event): Read special events also in
8247 batch mode. (Bug#11415)
8249 2012-05-12 Glenn Morris <rgm@gnu.org>
8251 * ns.mk: Update for ns_appbindir no longer having trailing "/".
8253 2012-05-12 Eli Zaretskii <eliz@gnu.org>
8255 * lisp.mk (lisp): Add newcomment.elc.
8257 2012-05-12 Glenn Morris <rgm@gnu.org>
8259 * Makefile.in (MKDIR_P): New, set by configure.
8260 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
8262 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
8264 Remove unused function hourglass_started.
8265 * dispextern.h (hourglass_started):
8266 * w32fns.c (hourglass_started):
8267 * xdisp.c (hourglass_started): Remove.
8269 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
8271 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
8272 Update dependencies.
8274 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
8276 * xgselect.c (xg_select): Put maxfds+1 into a var.
8277 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
8279 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
8281 2012-05-10 Dave Abrahams <dave@boostpro.com>
8283 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
8284 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
8286 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
8288 * dbusbind.c (xd_registered_buses): New internal Lisp object.
8289 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
8290 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
8291 Initialize xd_registered_buses.
8293 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
8295 Untag more efficiently if USE_LSB_TAG.
8296 This is based on a proposal by YAMAMOTO Mitsuharu in
8297 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
8298 For an admittedly artificial (nth 8000 longlist) benchmark on
8299 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
8300 Emacs's overall text size by 1%.
8301 * lisp.h (XUNTAG): New macro.
8302 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
8303 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
8304 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
8305 * eval.c (Fautoload):
8306 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
8307 * frame.h (XFRAME): Use XUNTAG.
8309 Port recent dbusbind.c changes to 32-bit --with-wide-int.
8310 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
8311 Remove unportable assumptions about print widths of types like
8313 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
8314 intptr_t when converting between pointer and integer, to avoid GCC
8315 warnings about wrong width.
8317 2012-05-09 Eli Zaretskii <eliz@gnu.org>
8319 * w32proc.c (new_child): Force Windows to reserve only 64KB of
8320 stack for each reader_thread, instead of defaulting to 8MB
8321 determined by the linker. This avoids failures in creating
8322 subprocesses on Windows 7, see the discussion in this thread:
8323 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
8325 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
8327 Fix up display of the *Minibuf-0* buffer in the mini window.
8328 * keyboard.c (read_char): Don't clear the echo area if there's no
8330 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
8331 contents of *Minibuf-0*) if there's no message displayed in its stead.
8333 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
8335 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
8338 2012-05-06 Chong Yidong <cyd@gnu.org>
8340 * lisp.mk (lisp): Update.
8342 2012-05-05 Jim Meyering <meyering@redhat.com>
8344 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
8346 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
8348 * data.c (PUT_ERROR): New macro.
8349 (syms_of_data): Use it. Add new error type `user-error'.
8350 * undo.c (user_error): New function.
8351 (Fprimitive_undo): Use it.
8352 * print.c (print_error_message): Adjust print style for `user-error'.
8353 * keyboard.c (user_error): New function.
8354 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
8356 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
8358 Do not limit current-time-string to years 1000..9999.
8359 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
8360 (Fcurrent_time_string): Support any year that is supported by the
8361 underlying localtime representation. Don't use asctime, as it
8362 has undefined behavior for years outside the range -999..9999.
8364 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
8366 Fix race conditions involving setenv, gmtime, localtime, asctime.
8367 Without this fix, interrupts could mess up code that uses these
8368 nonreentrant functions, since setting TZ invalidates existing
8369 tm_zone or tzname values, and since most of these functions return
8370 pointers to static storage.
8371 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
8372 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
8373 Grow the critical sections to include not just invoking
8374 localtime/gmtime, but also accessing these functions' results
8375 including their tm_zone values if any, and any related TZ setting.
8376 (format_time_string): Last arg is now struct tm *, not struct tm **,
8377 so that the struct tm is saved in the critical section.
8378 All callers changed. Simplify allocation of initial buffer, partly
8379 motivated by the fact that memory allocation needs to be outside
8380 the critical section.

8398 * xdisp.c (pos_visible_p): If already at a newline from the
8399 display string before the 'while' loop, don't walk back the glyphs
8400 from it3.glyph_row. Solves assertion violation when the display

8410 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
8411 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
8412 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
8413 All were removed before 23.1.

8429 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
8431 Do not avoid creating empty evaporating overlays (Bug#9642).
8432 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
8433 That is, do not delete an evaporating overlay if it becomes
8434 empty after its bounds are adjusted to fit within its buffer.
8435 This fix caused other problems, and I'm reverting it until we get
8436 to the bottom of them.
8438 2012-04-27 Chong Yidong <cyd@gnu.org>
8440 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).

8445 ZV, start the display from buffer beginning. Prevents assertion
8446 violation in init_iterator when the minibuffer window is scrolled
8449 * window.c (window_scroll_pixel_based): Likewise.
8451 2012-04-27 Chong Yidong <cyd@gnu.org>

8462 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
8463 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
8465 2012-04-26 Eli Zaretskii <eliz@gnu.org>
8467 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
8468 display element, check also the underlying string or buffer
8469 character. (Bug#11341)
8471 * w32menu.c: Include w32heap.h.
8472 (add_menu_item): If the call to AppendMenuW (via
8473 unicode_append_menu) fails, disable Unicode menus only if we are
8474 running on Windows 9X/Me.
8476 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
8478 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

8481 2012-04-24 Martin Rudalics <rudalics@gmx.at>
8483 * keyboard.c (read_char): Don't wipe echo area for select window

8489 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
8490 manipulation of :loaded-from data.
8492 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
8494 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
8495 now a cons (bug#11311).
8497 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
8499 Do not create empty overlays with the evaporate property (Bug#9642).
8500 * buffer.c (Fmove_overlay): Delete an evaporating overlay
8501 if it becomes empty after its bounds are adjusted to fit within
8502 its buffer. Without this fix, in a nonempty buffer (let ((o
8503 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
8504 yields an empty overlay that has the evaporate property, which is
8505 not supposed to happen.
8507 Fix minor GTK3 problems found by static checking.
8508 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

8648 2012-04-20 Chong Yidong <cyd@gnu.org>
8650 * process.c (wait_reading_process_output): If EIO occurs on a pty,

8782 against is gone. It's better to use vfork now so that when Cygwin
8783 gains a new, working vfork, we use it automatically (bug#10398).

8838 * minibuf.c (Fread_variable): Callers changed.
8840 2012-04-09 Eli Zaretskii <eliz@gnu.org>
8842 * xdisp.c (set_cursor_from_row): If the display string appears in
8843 the buffer at position that is closer to point than the position
8844 after the display string, display the cursor on the first glyph of
8845 the display string. Fixes cursor display when a 'display' text
8846 property immediately follows invisible text. (Bug#11094)
8848 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
8850 composite.c: use 'double' consistently
8851 * composite.c (get_composition_id): Use 'double' consistently
8852 instead of converting 'float' to 'double' and vice versa; this is
8853 easier to understand and avoids a GCC warning.
8855 2012-04-09 Glenn Morris <rgm@gnu.org>
8857 * Makefile.in: Generate leim-list with bootstrap-emacs, in
8858 preparation for dumping it with emacs. (Bug#4789)
8859 (leimdir): New variable.
8860 ($(leimdir)/leim-list.el): New rule.

8877 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
8879 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
8880 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
8881 (mark_memory): Mark Lisp_Objects only if pointers might hide in
8882 objects, as mark_maybe_pointer will catch them otherwise.
8883 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
8884 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
8886 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
8888 Fix typo that broke non-Windows builds.
8889 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

8893 Support building on MS-Windows with libxml2.
8895 * makefile.w32-in (OBJ2): Add xml.$(O).
8896 (GLOBAL_SOURCES): Add xml.c.
8897 ($(BLD)/xml.$(O)): New dependency list.
8899 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
8900 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
8901 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
8902 [!WINDOWSNT]: New macros.
8903 (init_libxml2_functions, libxml2_loaded_p): New functions.
8904 (parse_region): Call fn_xmlCheckVersion instead of using the macro
8905 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
8906 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
8907 Calls xmlCleanupParser only if libxml2 was loaded (or statically
8909 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
8910 Call init_libxml2_functions before calling libxml2 functions.
8911 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
8913 * emacs.c: Don't include libxml/parser.h.
8914 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
8915 xmlCleanupParser directly.
8917 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
8919 2012-04-07 Eli Zaretskii <eliz@gnu.org>
8921 * indent.c (Fvertical_motion): If there is a display string at
8922 point, use it.vpos to compute how many lines to backtrack after
8923 move_it_to point. (Bug#11133)
8925 2012-04-06 Eli Zaretskii <eliz@gnu.org>
8927 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
8928 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
8929 about subtle differences between FETCH_CHAR* and STRING_CHAR*
8930 macros related to unification of CJK characters. For the details,
8931 see the discussion following the message here:
8932 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
8934 2012-04-04 Chong Yidong <cyd@gnu.org>
8936 * keyboard.c (Vdelayed_warnings_list): Doc fix.
8938 2012-04-01 Eli Zaretskii <eliz@gnu.org>
8940 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
8941 instead of alloca. (Bug#11138)
8943 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
8945 * w32menu.c (is_simple_dialog): Properly check lisp types.
8948 2012-03-31 Eli Zaretskii <eliz@gnu.org>
8950 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
8951 position we get to after a call to move_it_to fails the
8952 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
8953 only if we wind up in a string from display property. (Bug#11063)
8955 * window.c (Fdelete_other_windows_internal): Invalidate the row
8956 and column information about mouse highlight, so that redisplay
8957 restores it after reallocating the glyph matrices. (Bug#7464)
8959 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
8960 string comes from a `display' text property, use the buffer
8961 position of that property as if we actually saw that position in
8963 (move_it_by_lines): Remove the assertion that
8964 "it->current_x == 0 && it->hpos == 0" which can be legitimately
8965 violated when there's a before-string at the beginning of a line.
8968 2012-03-30 Eli Zaretskii <eliz@gnu.org>
8970 * xdisp.c (append_space_for_newline): If the default face was
8971 remapped, use the remapped face for the appended newline.
8972 (extend_face_to_end_of_line): Use the remapped default face for
8973 extending the face to the end of the line.
8974 (display_line): Call extend_face_to_end_of_line when the default
8975 face was remapped. (Bug#11068)
8977 2012-03-29 Eli Zaretskii <eliz@gnu.org>
8979 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
8981 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
8983 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
8985 2012-03-27 Glenn Morris <rgm@gnu.org>
8987 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
8990 2012-03-26 Kenichi Handa <handa@m17n.org>
8992 * dispextern.h (struct glyph): Fix previous change. Change the
8993 bit length of glyphless.ch to 25 (Bug#11082).
8995 2012-03-26 Chong Yidong <cyd@gnu.org>
8997 * keyboard.c (Vselection_inhibit_update_commands): New variable.
8998 (command_loop_1): Use it; inhibit selection update for
8999 handle-select-window too (Bug#8996).
9001 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
9003 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
9005 2012-03-25 Kenichi Handa <handa@m17n.org>
9007 * dispextern.h (struct glyph): Change the bit length of
9008 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
9010 2012-03-24 Eli Zaretskii <eliz@gnu.org>
9012 * s/ms-w32.h (tzname): Include time.h before redirecting to
9013 _tzname. Fixes the MSVC build. (Bug#9960)
9015 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
9017 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
9020 * xterm.c (XTread_socket): Only modify handling_signal if
9021 !SYNC_INPUT. (Bug#11080)
9023 2012-03-23 Eli Zaretskii <eliz@gnu.org>
9025 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
9026 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
9027 when fetching a multibyte character consumes more bytes than
9028 CHAR_BYTES returns, due to unification of CJK characters in
9029 string_char. (Bug#11073)
9031 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
9033 * process.c (wait_reading_process_output): Handle pty disconnect
9034 by refraining from sending oneself a SIGCHLD (bug#10933).
9036 2012-03-22 Chong Yidong <cyd@gnu.org>
9038 * dispextern.h (struct it): New member string_from_prefix_prop_p.
9040 * xdisp.c (push_prefix_prop): Rename from push_display_prop.

9049 2012-03-20 Eli Zaretskii <eliz@gnu.org>
9051 * w32proc.c (Fw32_set_console_codepage)
9052 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
9055 2012-03-20 Chong Yidong <cyd@gnu.org>
9057 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
9058 to reflect default non-nil value of redisplay-dont-pause.
9060 2012-03-19 Kenichi Handa <handa@m17n.org>
9062 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
9063 it fit in a valid range (Bug#11003).
9065 2012-03-18 Eli Zaretskii <eliz@gnu.org>
9067 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
9068 that is not from display property, accept the row as a "cursor
9069 row" if one of the string's character has a non-nil `cursor'
9070 property. Fixes cursor positioning when there are newlines in
9071 overlay strings, e.g. in icomplete.el. (Bug#11035)
9073 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
9075 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
9077 2012-03-12 Chong Yidong <cyd@gnu.org>
9079 * eval.c (inhibit_lisp_code): Rename from
9080 inhibit_window_configuration_change_hook; move from window.c.
9082 * xfns.c (unwind_create_frame_1, Fx_create_frame):
9083 * window.c (run_window_configuration_change_hook)
9084 (syms_of_window): Callers changed.
9086 2012-03-11 Chong Yidong <cyd@gnu.org>

9095 is visible (Bug#10955).
9097 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
9099 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
9101 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
9103 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
9104 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
9107 2012-03-03 Glenn Morris <rgm@gnu.org>
9109 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
9111 2012-03-02 Eli Zaretskii <eliz@gnu.org>
9113 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
9114 position past the first glyph_row that ends at ZV. (Bug#10902)
9115 (redisplay_window, next_element_from_string): Fix typos in
9117 (redisplay_window): Pass to move_it_vertically the margin in
9118 pixels, not in screen lines.
9120 2012-03-02 Glenn Morris <rgm@gnu.org>
9122 * buffer.c (buffer-list-update-hook): Doc fix.
9124 2012-02-29 Eli Zaretskii <eliz@gnu.org>
9126 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
9127 push_it before setting up the iterator for the first overlay
9128 string, even if we have an empty string loaded.
9129 (next_overlay_string): If there's an empty string on the iterator
9130 stack, pop the stack. (Bug#10903)
9132 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
9134 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
9135 Suggested by Stefan Monnier in
9136 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
9137 * alloc.c (widen_to_Lisp_Object): New static function.
9138 (mark_memory): Also mark Lisp_Objects by fetching pointer words
9139 and widening them to Lisp_Objects. This would work even if
9140 USE_LSB_TAG is defined and wide integers are used, which might
9141 happen in a future version of Emacs.
9143 2012-02-25 Chong Yidong <cyd@gnu.org>
9145 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
9148 * xselect.c (Fx_selection_exists_p): Doc fix.
9149 (x_clipboard_manager_save_all): Print an informative message
9150 before saving to clipboard manager.
9152 2012-02-24 Chong Yidong <cyd@gnu.org>
9154 * keyboard.c (process_special_events): Handle all X selection
9155 requests in kbd_buffer, not just the next one (Bug#8869).
9157 2012-02-23 Chong Yidong <cyd@gnu.org>
9159 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
9160 call when setting menu-bar-lines and tool-bar-lines parameters.
9161 (unwind_create_frame_1): New helper function.
9163 * window.c (inhibit_window_configuration_change_hook): New var.
9164 (run_window_configuration_change_hook): Obey it.
9165 (syms_of_window): Initialize it.
9167 2012-02-22 Chong Yidong <cyd@gnu.org>

9182 when computing $valmask.
9184 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
9185 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
9186 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
9187 It's useless in that case, and it can cause problems on hosts
9188 that allocate halves of EMACS_INT values separately.
9189 Reported by Dan Horák. Diagnosed by Andreas Schwab in
9190 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
9191 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
9192 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
9193 it avoids undefined behavior on hosts where shifting right by more
9194 than the word width has undefined behavior.
9196 2012-02-19 Chong Yidong <cyd@gnu.org>
9198 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
9199 (Funhandled_file_name_directory, Ffile_name_as_directory)

9202 return values (Bug#10845).
9204 2012-02-18 Eli Zaretskii <eliz@gnu.org>
9206 * .gdbinit (pitx): Fix incorrect references to fields of the

9216 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
9218 2012-02-15 Chong Yidong <cyd@gnu.org>
9220 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
9221 marked as special. Also, starting docstrings with * is obsolete.
9223 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>

9236 2012-02-12 Chong Yidong <cyd@gnu.org>
9238 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
9239 as that creates a dangerous corner case.
9241 * window.c (Fdelete_window_internal): Invalidate the mouse
9242 highlight (Bug#9904).
9244 2012-02-12 Glenn Morris <rgm@gnu.org>
9246 * xselect.c (Fx_own_selection_internal)
9247 (Fx_get_selection_internal, Fx_disown_selection_internal)
9248 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
9249 * nsselect.m (Fx_own_selection_internal)
9250 (Fx_disown_selection_internal, Fx_selection_exists_p)
9251 (Fx_selection_owner_p, Fx_get_selection_internal):
9252 Sync docs and argument specs with the xselect.c versions.
9254 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

9274 2012-02-07 Chong Yidong <cyd@gnu.org>
9276 * buffer.c (Fbuffer_local_variables)
9277 (buffer_lisp_local_variables): Handle unbound vars correctly;
9278 don't let Qunbound leak into Lisp.
9280 2012-02-07 Glenn Morris <rgm@gnu.org>
9282 * image.c (Fimagemagick_types): Doc fix.
9284 * image.c (imagemagick-render-type): Change it from a lisp object
9285 to an integer. Move the doc here from the lisp manual.

9288 2012-02-06 Chong Yidong <cyd@gnu.org>
9290 * doc.c (store_function_docstring): Avoid applying docstring of
9291 alias to base function (Bug#2603).

9309 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
9310 after rounding frame sizes. (Bug#9723)
9312 2012-02-04 Eli Zaretskii <eliz@gnu.org>
9314 * keyboard.c (adjust_point_for_property): Don't position point
9315 before BEGV. (Bug#10696)
9317 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
9319 Handle overflow when computing char display width (Bug#9496).
9320 * character.c (char_width): Return EMACS_INT, not int.
9321 (char_width, c_string_width): Check for overflow when
9322 computing the width; this is possible now that individual
9323 characters can have unbounded width. Problem introduced
9324 by merge from Emacs 23 on 2012-01-19.
9326 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
9328 * dbusbind.c (Fdbus_register_method): Mention the return value

9888 * xdisp.c (redisplay_window): If cursor row is not fully visible
9889 after recentering, and scroll-conservatively is set to a large
9890 number, scroll window by a few more lines to make the cursor fully
9891 visible and out of scroll-margin. (Bug#10105)
9892 (start_display): Don't move to the next line if the display should

9975 Problem reported by Andreas Schwab in
9976 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
9977 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
9978 is set, removing the need for VIRT_ADDRESS_VARIES.
9979 (PURE_P): Use a more-efficient implementation that needs just one
9980 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
9981 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
9982 to 4 (xorl, subq, cmpq, setbe).
9983 * alloc.c (pure): Always extern now, since that's the
9984 VIRT_ADDR_VARIES behavior.
9985 (PURE_POINTER_P): Use a single comparison, not two, for
9986 consistency with the new puresize.h.
9987 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
9988 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

9994 (erase_phys_cursor, update_window_cursor, show_mouse_face)
9995 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
9996 behave as if the cursor position were at the window margin.
9998 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
9999 and the cursor position is out of bounds, behave as if the cursor
10000 position were at the window margin. (Bug#10075)
10002 2011-11-18 Chong Yidong <cyd@gnu.org>
10004 * window.c (Fwindow_combination_limit): Make first argument

10025 * xdisp.c (row_hash): New function, body extracted from
10026 compute_line_metrics.
10027 (compute_line_metrics): Call row_hash, instead of computing the
10030 * dispnew.c (verify_row_hash): Call row_hash for computing the
10031 hash code of a row, instead of duplicating code from xdisp.c.
10033 * dispextern.h (row_hash): Add prototype.
10035 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
10037 * frame.c (delete_frame): Don't delete the terminal when the last

10063 (Fsplit_window_internal, saved_window)
10064 (Fset_window_configuration, save_window_save): Rename all
10065 occurrences of window_nest to window_combination_limit.
10067 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
10069 * image.c (imagemagick_load_image): Fix typo.
10071 2011-11-14 Eli Zaretskii <eliz@gnu.org>
10073 * xdisp.c (display_line): Move the call to
10074 highlight_trailing_whitespace before the call to
10075 compute_line_metrics, since the latter needs to see the final
10076 faces of all the glyphs to compute ROW's hash value.
10077 Fixes assertion violations in row_equal_p. (Bug#10035)
10079 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
10081 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
10082 just return (bug#10044).
10084 2011-11-12 Eli Zaretskii <eliz@gnu.org>
10086 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
10087 with user-defined heap size. Bump the default size of the temacs

10091 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
10092 current_matrix and desired_matrix. (Bug#9990)
10093 (verify_row_hash) [XASSERTS]: New function.
10094 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify

10138 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
10140 Avoid some portability problems by eschewing 'extern inline' functions.
10141 The trivial performance wins aren't worth the portability hassles; see
10142 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
10144 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
10145 (window_box_width, window_box_left, window_box_left_offset)
10146 (window_box_right, window_box_right_offset): Undo previous change,
10147 by removing the "extern"s.
10148 * intervals.c (adjust_intervals_for_insertion)
10149 (adjust_intervals_for_deletion): Undo previous change,
10150 making these static again.
10151 (offset_intervals, temp_set_point_both, temp_set_point)
10152 (copy_intervals_to_string): No longer inline.
10153 * xdisp.c (window_text_bottom_y, window_box_width)

10210 * xmenu.c (cleanup_widget_value_tree): New function.
10211 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

10218 (window_box_width, window_box_left, window_box_left_offset)
10219 (window_box_right, window_box_right_offset): Declare extern.
10220 Otherwise, these inline functions do not conform to C99 and
10221 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
10222 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
10223 * intervals.c (adjust_intervals_for_insertion)
10224 (adjust_intervals_for_deletion): Now extern, because otherwise the
10225 extern inline functions 'offset_intervals' couldn't refer to it.
10226 (static_offset_intervals): Remove.
10227 (offset_intervals): Rewrite using the old contents of
10228 static_offset_intervals. The old version didn't conform to C99
10229 because an extern inline function contained a reference to an
10230 identifier with static linkage.

10283 (unwind_create_frame): New function (Bug#9943).
10284 (Fx_create_frame): Restructure code to be more similar to the one in
10285 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).

10296 official. Move initialization of image_cache_refcount and
10297 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

10376 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
10377 past the beginning of the current glyph matrix.

10452 2011-10-28 Eli Zaretskii <eliz@gnu.org>
10454 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
10455 <oslsachem@gmail.com> for helping to debug this.

10463 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
10465 (w32font_open_internal, compute_metrics):
10466 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
10467 instead of calling the "wide" APIs directly.
10469 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
10471 * w32.h (syms_of_w32font): Add prototype.

10477 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
10478 (Fmove_to_window_line): Doc fix.
10480 2011-10-27 Chong Yidong <cyd@gnu.org>
10482 * process.c (make_process): Set gnutls_state to NULL.
10484 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
10485 non-NULL, regardless of GNUTLS_INITSTAGE.
10486 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
10487 an error. Set process slots as soon as we allocate them.

10513 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
10515 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
10517 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
10519 * keyboard.c (test_undefined): New function (bug#9751).
10520 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
10522 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
10524 * sysdep.c (init_sys_modes): Fix the check for the controlling
10525 terminal (Bug#6649).
10527 2011-10-20 Eli Zaretskii <eliz@gnu.org>
10529 * dispextern.h (struct bidi_it): New member next_en_type.
10531 * bidi.c (bidi_line_init): Initialize the next_en_type member.
10532 (bidi_resolve_explicit_1): When next_en_pos is valid for the
10533 current character, check also for next_en_type being WEAK_EN.
10534 (bidi_resolve_weak): Don't enter the expensive loop if the current
10535 position is before next_en_pos. Record the bidi type of the first
10536 non-ET, non-BN character we find, in addition to its position.
10537 (bidi_level_of_next_char): Invalidate next_en_type when
10538 next_en_pos is over-stepped.
10540 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
10542 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
10543 * editfns.c: Rewrite current-time-zone so that it invokes
10544 the equivalent of (format-time-string "%Z") to get the time zone name.
10545 This fixes a bug when the time zone name contains characters that
10546 need converting from the system time locale to Emacs internal format.
10547 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
10548 that patch fixed format-time-string to do the conversion, but
10549 I forgot to fix current-time-zone.
10550 (format_time_string): New function, containing most of
10551 what Fformat_time_string used to contain.
10552 (Fformat_time_string): Rewrite in terms of format_time_string.
10553 This doesn't change this function's behavior.
10554 (current-time-zone): Rewrite to use format_time_string.
10555 This fixes the bug reported by Michael Schierl in
10556 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
10557 Jason Rumney's 2007-06-07 change worked around this bug, but
10559 * systime.h (tzname, timezone): Remove no-longer-used declarations.
10561 2011-10-19 Eli Zaretskii <eliz@gnu.org>
10563 * xdisp.c (start_display): If the character at POS is displayed
10564 via a display vector, reset IT->current.dpvec_index to zero.
10565 (try_window_reusing_current_matrix): If a line ends in a display
10566 vector or the next line starts in a display vector, continue
10567 redrawing the window even though the character position of
10568 start_row was reached.
10571 2011-10-18 Chong Yidong <cyd@gnu.org>
10573 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
10574 with nobreak-char-display too.
10576 2011-10-18 Eli Zaretskii <eliz@gnu.org>
10578 Fix part 3 of bug#9771.
10579 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
10580 (bidi_resolve_neutral): Don't enter the expensive loop looking for
10581 non-neutral characters if the current character is a paragraph
10582 separator (a.k.a. Newline). This avoids running the same
10583 expensive loop twice, once when we consume the preceding newline
10584 and the other time when the line actually needs to be displayed.
10585 Avoid the loop when we see neutrals on the base embedding level
10586 following a character whose directionality is the same as the
10587 paragraph's. This avoids running the expensive loop when a line
10588 ends in a long sequence of neutrals, like control characters.
10589 Add assertion against STRONG_AL type. Slightly rearrange code
10590 that determines the type of a neutral given the first non-neutral
10592 (bidi_level_of_next_char): Set next_en_pos to zero when
10593 invalidating its info.
10595 2011-10-17 Eli Zaretskii <eliz@gnu.org>
10597 * xdisp.c (push_display_prop): Determine whether to record string
10598 or buffer position by IT->string, not by IT->method. Allow
10599 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
10600 (move_it_vertically_backward): Don't look for character position
10601 immediately after the newline when in a continuation line.
10604 2011-10-15 Martin Rudalics <rudalics@gmx.at>
10606 * window.c (coordinates_in_window): Rewrite and delabelize
10607 vertical border check. (Bug#5357) (Bug#9618)
10609 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
10611 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
10612 errors in XSetWindowBorder (bug#9310).
10614 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
10616 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
10617 avoid crash when xmalloc overrun checking is enabled.
10619 2011-10-13 Eli Zaretskii <eliz@gnu.org>
10621 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
10622 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
10623 cursor motion with <left> and <right> arrow keys.
10625 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
10626 some callers set that themselves.
10628 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10630 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
10631 display string and the previous row comes from the same string and
10632 is empty. (Bug#9739) (Bug#9738)
10634 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
10636 * doc.c (get_doc_string): Encode file name (bug#9735).
10638 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10640 * bidi.c (bidi_level_of_next_char):
10641 * xdisp.c (get_visually_first_element): Remove old incorrect
10642 comments regarding the Unicode Line Separator character.
10644 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
10646 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
10648 * alloc.c (Fgc_status): Do not access beyond zombies array
10649 boundary if nzombies > MAX_ZOMBIES.
10650 * alloc.c (dump_zombies): Add missing format specifier.
10652 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
10654 * xdisp.c (set_cursor_from_row): Simplify conditionals,
10655 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
10657 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
10658 Some packages use them to denote characters with modifiers.
10660 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
10662 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
10663 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
10664 matching a pp-number. Rename parameter var to var1.
10666 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
10668 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
10670 2011-10-08 Glenn Morris <rgm@gnu.org>
10672 * callint.c (Fcall_interactively): Give a more explicit error for the
10673 'c' case with a non-character input. (Bug#8479)
10675 2011-10-08 Eli Zaretskii <eliz@gnu.org>
10677 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
10679 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
10680 lines that are hscrolled on the left.
10682 * dispnew.c (buffer_posn_from_coords): Account for a possible
10683 presence of header-line. (Bug#4426)
10685 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
10687 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
10688 Don't advertise functionality which we discourage or doesn't work.
10690 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
10692 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
10693 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
10694 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
10695 this makes Emacs dump core during garbage collection on rare
10696 occasions. sizeof is obviously inferior to offsetof here, so
10697 stick with offsetof.
10698 (GC_POINTER_ALIGNMENT): New macro.
10699 (mark_memory): Omit 3rd (offset) arg; caller changed.
10700 Don't assume EMACS_INT alignment is the same as pointer alignment.
10702 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
10704 * keyboard.c (read_key_sequence_remapped): New var.
10705 (read_key_sequence): Compute remapping in the right buffer.
10706 (command_loop_1): Use read_key_sequence's remapping directly.
10708 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
10710 * dired.c (file_name_completion): Don't expand file name.
10711 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
10712 before checking file name handler.
10714 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
10715 they've been requested explicitly (bug#9591).
10717 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
10719 * keymap.c (Fsingle_key_description): Use make_specified_string
10720 instead of build_string to build string from push_key_description.
10723 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10725 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
10726 This fixes a Y2038 bug on 64-bit hosts.
10727 * buffer.c (reset_buffer):
10728 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
10729 (Fclear_buffer_auto_save_failure):
10730 Use 0, not -1, to represent an unset failure time, since time_t
10731 might not be signed.
10733 Remove dependency on glibc malloc internals.
10734 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10735 Move back here from lisp.h, but with their new implementations.
10736 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10737 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
10738 * charset.c (charset_table_init): New static var.
10739 (syms_of_charset): Use it instead of xmalloc. This removes a
10740 dependency on glibc malloc internals. See Eli Zaretskii's comment in
10741 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
10742 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10743 Move back to alloc.c.
10744 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10745 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
10747 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
10749 * nsterm.m (windowDidResize): Call x_set_window_size only when
10750 ns_in_resize is true. Otherwise set pixelwidth/height and
10751 call change_frame_size (Bug#9628).
10753 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10755 Port --enable-checking=all to Fedora 14 x86-64.
10756 * charset.c (syms_of_charset): Also account for glibc malloc's
10757 internal overhead when calculating the initial malloc maximum.
10759 Port --enable-checking=all to Fedora 14 x86.
10760 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10762 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
10763 (overrun_check_realloc, overrun_check_free):
10764 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
10765 That way, xmalloc returns a properly-aligned pointer even if
10766 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
10767 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
10768 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
10769 into account when calculating the initial malloc maximum.
10770 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10771 Move here from alloc.c, so that charset.c can use it too.
10772 Properly align; the old code wasn't right for common 32-bit hosts
10773 when configured with --enable-checking=all.
10774 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10775 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
10777 2011-09-29 Eli Zaretskii <eliz@gnu.org>
10779 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
10782 2011-09-28 Eli Zaretskii <eliz@gnu.org>
10784 * xdisp.c (compute_display_string_end): If there's no display
10785 string at CHARPOS, return -1.
10787 * bidi.c (bidi_fetch_char): When compute_display_string_end
10788 returns a negative value, treat the character as a normal
10789 character not covered by a display string. (Bug#9624)
10791 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
10793 * lread.c (Fread_from_string): Fix typo in docstring.
10795 2011-09-27 Eli Zaretskii <eliz@gnu.org>
10797 * xdisp.c (handle_invisible_prop): If invisible text ends on a
10798 newline, reseat the iterator instead of bidi-iterating there one
10799 character at a time. (Bug#9610)
10800 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
10801 TO_CHARPOS if the bidi iterator is at base embedding level.
10803 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
10805 * lread.c (readevalloop): Use correct code for NBSP.
10806 (read1): Likewise. (Bug#9608)
10808 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
10810 * dbusbind.c (Fdbus_register_signal): When service is not
10811 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
10813 2011-09-25 Glenn Morris <rgm@gnu.org>
10815 * buffer.c (truncate-lines): Doc fix.
10817 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
10819 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
10820 (Fset_window_next_buffers): Doc fix.
10822 2011-09-24 Glenn Morris <rgm@gnu.org>
10824 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
10826 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
10828 Fix minor problems found by static checking.
10829 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
10830 * indent.c (Fvertical_motion): Fix == vs = typo.
10832 2011-09-24 Eli Zaretskii <eliz@gnu.org>
10834 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
10835 Default value is now t. Doc fix.
10837 * indent.c (Fvertical_motion): Compute and apply the overshoot
10838 logic when moving up, not only when moving down. Fix the
10839 confusing name and values of the it_overshoot_expected variable;
10840 logic changes accordingly. (Bug#9254) (Bug#9549)
10842 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
10843 CHARPOS is covered by a display string which includes newlines.
10844 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
10845 is covered by a display string with embedded newlines.
10847 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
10849 * dbusbind.c (Fdbus_register_signal): Add match rule to
10850 Vdbus_registered_objects_table. (Bug#9581)
10851 (Fdbus_register_method, Vdbus_registered_objects_table):
10854 2011-09-24 Jim Meyering <meyering@redhat.com>
10856 do not ignore write error for any output size
10857 The previous change was incomplete.
10858 While it makes emacs --batch detect the vast majority of stdout
10859 write failures, errors were still ignored whenever the output size is
10860 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
10861 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
10862 && echo FAIL: ignored write error
10863 FAIL: ignored write error
10864 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
10865 && echo FAIL: ignored write error
10866 FAIL: ignored write error
10867 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
10869 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
10871 * emacs.c (Fkill_emacs): In noninteractive mode exit
10872 non-successfully if a write error occurred on stdout. (Bug#9574)
10874 2011-09-21 Eli Zaretskii <eliz@gnu.org>
10876 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
10879 * dispextern.h (struct it): Update the comment documenting what
10882 2011-09-20 Eli Zaretskii <eliz@gnu.org>
10884 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
10885 a display string, extend search for cursor position to end of row.
10886 (find_row_edges): If the row ends in a newline from a display
10887 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
10888 Handle the case of a display string with multiple newlines.
10889 (Fcurrent_bidi_paragraph_direction): Fix search for previous
10890 non-empty line. Fixes confusing cursor motion with arrow keys at
10891 the beginning of a line that starts with whitespace.
10893 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
10895 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
10898 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
10900 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
10901 boolean (Bug#9154).
10903 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10905 * xdisp.c (display_line): Record maximum and minimum buffer
10906 positions even if no glyphs were produced (e.g., by a zero-width
10907 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
10908 buffer positions that will be removed from the glyph row because
10910 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
10911 column is beyond frame width: don't subtract 1 "pixel" when
10912 computing width of the stretch.
10913 (reseat_at_next_visible_line_start): Undo the change made on
10914 2011-09-17 that saved paragraph information and restored it after
10915 the call to `reseat'. (Bug#9545)
10917 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10919 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
10920 and turn window cursor on if cleared (Bug#9415).
10922 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
10924 * search.c (boyer_moore): Take unibyte characters from pattern
10925 literally. (Bug#9458)
10927 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10929 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
10931 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
10933 Fix minor problem found by static checking.
10934 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
10935 initialized, to pacify gcc -Wuninitialized.
10937 * fileio.c: Report proper errno when syscall falls.
10938 (Finsert_file_contents): Save and restore errno,
10939 so that report_file_error outputs the correct diagnostic.
10940 (Fwrite_region) [CLASH_DETECTION]: Likewise.
10942 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10944 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
10946 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10948 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
10949 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
10951 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10953 * xdisp.c (reseat_at_next_visible_line_start): Keep information
10954 about the current paragraph and restore it after the call to reseat.
10956 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
10957 (bidi_find_paragraph_start): Search back for paragraph beginning
10958 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
10959 (bidi_move_to_visually_next): Only trigger paragraph-related
10960 computations when the last character is a newline or at EOB, not
10961 just any NEUTRAL_B. (Bug#9470)
10963 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
10964 truncated lines if point is covered by a display string. (Bug#9524)
10966 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
10968 * xselect.c: Relax test for outgoing X longs (Bug#9498).
10969 (cons_to_x_long): New function.
10970 (lisp_data_to_selection_data): Use it. Correct the test for
10971 short-versus-long data; it was negated. Break out of vector
10972 loop, for efficiency, when a long datum is discovered.
10974 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
10976 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
10978 2011-09-16 Eli Zaretskii <eliz@gnu.org>
10980 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
10981 GCC PR/17406) by declaring this function with external scope.
10983 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10985 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
10986 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
10988 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
10990 * editfns.c (Fformat): Correctly handle text properties on "%%".

10998 * xdisp.c (get_next_display_element)
10999 (fill_composite_glyph_string): Add comments about special meaning
11000 of TAB characters in a composition.
11002 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11004 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
11005 This occurs when processing a multibyte format.
11006 Problem reported by Wolfgang Jenker.
11008 2011-09-15 Johan Bockgård <bojohan@gnu.org>
11010 * xdisp.c (try_cursor_movement): Only check for exact match if
11011 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
11013 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
11015 Remove unused external symbols.
11016 * dispextern.h (calc_pixel_width_or_height): Remove decl.
11017 * xdisp.c (calc_pixel_width_or_height): Now static.
11018 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
11019 * indent.c (check_display_width):
11020 * w32term.c: Fix comment to match code.
11021 * xterm.c, xterm.h (x_catching_errors): Remove.
11023 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
11025 * xselect.c: Use signed conversions more consistently (Bug#9498).
11026 (selection_data_to_lisp_data): Assume incoming selection data are
11027 signed integers, not unsigned. This is to be consistent with
11028 outgoing selection data, which was modified to use signed integers
11029 in as part of the fix to Bug#9196 in response to Jan D.'s comment
11030 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
11031 expects long, not unsigned long.
11033 2011-09-14 Eli Zaretskii <eliz@gnu.org>
11035 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
11036 computation of loop end. Reported by Johan Bockgård
11039 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
11041 * frame.c (Fother_visible_frames_p): Function deleted.
11043 2011-09-12 Eli Zaretskii <eliz@gnu.org>
11045 * indent.c (compute_motion): Process display vector front to back
11046 rather than the other way around. (Bug#2496)
11048 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
11050 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
11052 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
11054 * minibuf.c (Fread_from_minibuffer): Doc fix.
11056 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11058 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
11059 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
11061 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
11063 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
11064 value for non-existent files.
11066 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11068 * fileio.c (Finsert_file_contents): If the file cannot be opened,
11069 set its "size" to -1. This will set the modtime_size field of
11070 the corresponding buffer to -1, which is what
11071 verify-visited-file-modtime expects for files that do not exist.
11074 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
11076 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
11078 * lisp.h: ... from here. push_key_description is no longer
11079 defined in keyboard.c, so its declaration should not be in
11080 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
11081 logically belongs with push_key_description.
11083 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
11085 * buffer.h: Include <sys/types.h> instead of <time.h>.
11086 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
11087 Problem reported by Herbert J. Skuhra.
11089 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
11091 * xml.c (parse_region): Make the parsing work for
11092 non-comment-starting XML files again (bug#9144).
11094 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
11096 * image.c (gif_load): Fix calculation of bottom and right corner.
11099 2011-09-10 Eli Zaretskii <eliz@gnu.org>
11101 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
11102 redisplay in small windows.
11104 2011-09-09 Eli Zaretskii <eliz@gnu.org>
11106 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
11108 2011-09-08 Martin Rudalics <rudalics@gmx.at>
11110 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
11111 Operate on live windows only.
11113 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
11115 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
11117 2011-09-07 Eli Zaretskii <eliz@gnu.org>
11119 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
11120 only under bidi iteration.
11122 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
11124 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
11126 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11128 isnan: Fix porting problem to Solaris 10 with bundled gcc.
11129 Without this fix, the command to link temacs failed due to an
11130 undefined symbol __builtin_isnan. This is because
11131 /usr/include/iso/math_c99.h #defines isnan(x) to
11132 __builtin_isnan(x), but the bundled gcc, which identifies itself
11133 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
11135 * floatfns.c (isnan): #undef, and then #define to a clone of
11137 (Fisnan): Always define, since it's always available now.
11138 (syms_of_floatfns): Always define isnan at the Lisp level.
11140 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11142 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
11144 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11146 * fileio.c: Fix bugs with large file offsets (Bug#9428).
11147 The previous code assumed that file offsets (off_t values) fit in
11148 EMACS_INT variables, which is not true on typical 32-bit hosts.
11149 The code messed up by falsely reporting buffer overflow in cases
11150 such as (insert-file-contents "big" nil 1 2) into an empty buffer
11151 when "big" contains more than 2**29 bytes, even though this
11152 inserts just one byte and does not overflow the buffer.
11153 (Finsert_file_contents): Store file offsets as off_t
11154 values, not as EMACS_INT values. Check for overflow when
11155 converting between EMACS_INT and off_t. When checking for
11156 buffer overflow or for overlap, take the offsets into account.
11157 Don't use EMACS_INT for small values where int suffices.
11158 When checking for overlap, fix a typo: ZV was used where
11159 ZV_BYTE was intended.
11160 (Fwrite_region): Don't assume off_t fits into 'long'.
11161 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
11163 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
11165 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
11167 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
11169 sprintf-related integer and memory overflow issues (Bug#9412).
11171 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
11172 (esprintf, exprintf, evxprintf): New functions.
11173 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
11174 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
11175 (modify_event_symbol): Do not assume that the length of
11176 name_alist_or_stem is safe to alloca and fits in int.
11177 (Fexecute_extended_command): Likewise for function name and binding.
11178 (Frecursion_depth): Wrap around reliably on integer overflow.
11179 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
11180 since some callers pass EMACS_INT values.
11181 (Fsingle_key_description): Don't crash if symbol name contains more
11182 than MAX_ALLOCA bytes.
11183 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
11184 (get_minibuffer): Arg is now EMACS_INT, not int.
11185 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
11186 (esprintf, exprintf, evxprintf): New decls.
11187 * window.h (command_loop_level, minibuf_level): Reflect API changes.
11189 * dbusbind.c (signature_cat): New function.
11190 (xd_signature, Fdbus_register_signal):
11191 Do not overrun buffer; instead, report string overflow.
11193 * dispnew.c (add_window_display_history): Don't overrun buffer.
11194 Truncate instead; this is OK since it's just a log.
11196 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
11197 even if the time zone offset is outlandishly large.
11198 Don't mishandle offset == INT_MIN.
11200 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
11201 when creating daemon; the previous buffer-overflow check was incorrect.
11203 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
11204 which has the guts of the old verror function.
11206 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
11207 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
11209 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
11210 (font_unparse_xlfd): Don't blindly alloca long strings.
11211 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
11212 fits in int, when using sprintf. Use single snprintf to count
11213 length of string rather than counting it via multiple sprintfs;
11214 that's simpler and more reliable.
11215 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
11216 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
11217 sprintf, in case result does not fit in int.
11219 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
11220 (fontset_from_font): Print it.
11222 * frame.c (tty_frame_count): Now printmax_t, not int.
11223 (make_terminal_frame, set_term_frame_name): Print it.
11224 (x_report_frame_params): In X, window IDs are unsigned long,
11225 not signed long, so print them as unsigned.
11226 (validate_x_resource_name): Check for implausibly long names,
11227 and don't assume name length fits in 'int'.
11228 (x_get_resource_string): Don't blindly alloca invocation name;
11229 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
11232 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
11233 (xg_check_special_colors, xg_set_geometry):
11234 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
11236 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
11237 Use esprintf, not sprintf, in case result does not fit in int.
11239 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11240 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
11241 it as a large positive number.
11242 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
11243 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11245 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
11246 in case result does not fit in int.
11248 * print.c (float_to_string): Detect width overflow more reliably.
11249 (print_object): Make sprintf buffer a bit bigger, to avoid potential
11250 buffer overrun. Don't assume list length fits in 'int'. Treat
11251 print length of 0 as 0, not as infinity; to be consistent with other
11252 uses of print length in this function. Don't overflow print length
11253 index. Don't assume hash table size fits in 'long', or that
11254 vectorlike size fits in 'unsigned long'.
11256 * process.c (make_process): Use printmax_t, not int, to format
11257 process-name gensyms.
11259 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
11261 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
11262 to avoid potential buffer overrun.
11264 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
11265 if X resource line is longer than 512 bytes.
11267 * xfns.c (x_window): Make sprintf buffer a bit bigger
11268 to avoid potential buffer overrun.
11270 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
11272 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
11274 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
11276 Integer overflow fixes for scrolling, etc.
11277 Without these, Emacs silently mishandles large integers sometimes.
11278 For example, "C-u 4294967297 M-x recenter" was treated as if
11279 it were "C-u 1 M-x recenter" on a typical 64-bit host.
11281 * xdisp.c (try_window_id): Check Emacs fixnum range before
11282 converting to 'int'.
11284 * window.c (window_scroll_line_based, Frecenter):
11285 Check that an Emacs fixnum is in range before assigning it to 'int'.
11286 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
11287 values converted from Emacs fixnums.
11288 (Frecenter): Don't wrap around a line count if it is out of 'int'
11289 range; instead, treat it as an extreme value.
11290 (Fset_window_configuration, compare_window_configurations):
11291 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
11293 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
11294 that can exceed INT_MAX. Check that EMACS_INT value is in range
11295 before assigning it to the (possibly-narrower) index.
11296 (match_limit): Don't assume that a fixnum can fit in 'int'.
11298 * print.c (print_object): Use ptrdiff_t, not int, for index that can
11301 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
11302 (Fvertical_motion): Don't wrap around LINES values that don't fit
11303 in 'int'. Instead, treat them as extreme values. This is good
11304 enough for windows, which can't have more than INT_MAX lines anyway.
11306 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
11308 * Require libxml/parser.h to avoid compilation warning.
11310 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
11312 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
11313 since this reportedly can destroy thread storage.
11315 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
11317 * syntax.c (find_defun_start): Update all cache variables if
11318 exiting early (Bug#9401).
11320 2011-08-30 Eli Zaretskii <eliz@gnu.org>
11322 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
11324 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
11325 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
11326 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
11328 * term.c (tty_append_glyph): New function.
11329 (produce_stretch_glyph): Static function and its prototype deleted.
11331 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
11334 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
11336 * image.c (parse_image_spec): Check for nonnegative, not for positive,
11337 when checking :margin (Bug#9390).
11338 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
11339 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
11340 so that the name doesn't mislead. All uses changed.
11342 2011-08-28 Johan Bockgård <bojohan@gnu.org>
11344 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
11347 2011-08-27 Eli Zaretskii <eliz@gnu.org>
11349 * xdisp.c (move_it_to): Don't bail out early when reaching
11350 position beyond to_charpos, if we are scanning backwards.
11351 (move_it_vertically_backward): When DY == 0, make sure we get to
11352 the first character in the line after the newline.
11354 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
11356 * ccl.c: Improve and simplify overflow checking (Bug#9196).
11357 (ccl_driver): Do not generate an out-of-range pointer.
11358 (Fccl_execute_on_string): Remove unnecessary check for
11359 integer overflow, noted by Stefan Monnier in
11360 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
11361 Remove a FIXME that didn't need fixing.
11362 Simplify the newly-introduced buffer reallocation code.
11364 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
11366 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
11368 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
11370 Integer and memory overflow issues (Bug#9196).
11372 * doc.c (get_doc_string): Rework so that
11373 get_doc_string_buffer_size is the actual buffer size, rather than
11374 being 1 less than the actual buffer size; this makes xpalloc more
11377 * image.c (x_allocate_bitmap_record, cache_image):
11378 * xselect.c (Fx_register_dnd_atom):
11379 Simplify previous changes by using xpalloc.
11381 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
11382 since either will do and ptrdiff_t is convenient with xpalloc.
11384 * charset.c (charset_table_size)
11385 (struct charset_sort_data.priority): Now ptrdiff_t.
11386 (charset_compare): Don't overflow if priorities differ greatly.
11387 (Fsort_charsets): Don't assume list length fits in int.
11388 Check for size-calculation overflow when allocating sort data.
11389 (syms_of_charset): Allocate an initial charset table that is
11390 just under 64 KiB, to avoid problems with glibc malloc and mmap.
11392 * cmds.c (internal_self_insert): Check for size-calculation overflow.
11394 * composite.h (struct composition.glyph_len): Now int, not unsigned.
11395 The actual value is always <= INT_MAX, and leaving it unsigned made
11396 overflow checking harder.
11398 * dispextern.h (struct glyph_matrix.rows_allocated)
11399 (struct face_cache.size): Now ptrdiff_t, for convenience in use
11400 with xpalloc. The values are still always <= INT_MAX.
11402 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
11404 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
11405 (SAFE_NALLOCA): New macro.
11407 * region-cache.c (struct boundary.pos, find_cache_boundary)
11408 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
11409 (set_cache_region, invalidate_region_cache)
11410 (revalidate_region_cache, know_region_cache, region_cache_forward)
11411 (region_cache_backward, pp_cache):
11412 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
11413 so that ptrdiff_t * can be passed to xpalloc.
11414 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
11415 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
11416 (pp_cache): Don't assume cache_len fits in int.
11417 * region-cache.h: Adjust extern decls to match.
11419 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
11420 EMACS_INT, since either will do, for xpalloc.
11422 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
11423 (xnmalloc, xnrealloc, xpalloc): New functions.
11425 * bidi.c (bidi_shelve_header_size): New constant.
11426 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
11427 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
11429 * bidi.c (bidi_cache_shrink):
11430 * buffer.c (overlays_at, overlays_in, record_overlay_string)
11432 Don't update size of array until after memory allocation succeeds,
11433 because xmalloc/xrealloc may not return.
11434 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
11435 now that we have proper integer overflow checking.
11436 (record_overlay_string, overlay_strings): Catch overflows when
11437 calculating size of overlay_str_buf.
11439 * callproc.c (Fcall_process): Check for size overflow when
11440 calculating size of args2.
11441 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
11442 Normally we prefer signed values, but sticking with ptrdiff_t would
11443 require adding more-complicated checks.
11445 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
11446 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
11447 Redo buffer-overflow calculations to avoid integer overflow.
11448 Add a FIXME comment where memory seems to be over-allocated.
11450 * character.c (Fstring): Check for size-calculation overflow.
11452 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
11453 unnecessary integer overflow. Check for size overflow.
11454 (encode_coding_object): Don't update size until xmalloc succeeds.
11456 * composite.c (get_composition_id): Check for overflow in glyph
11457 length calculations.
11459 Integer and memory overflow fixes for display code.
11460 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
11461 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
11462 (scrolling_window): Check for overflow in size calculations.

11474 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
11475 (get_doc_string): Check for size calculation overflow.
11476 Don't update size until allocation succeeds.
11477 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
11478 EMACS_INT, where ptrdiff_t will do.
11479 (Fsubstitute_command_keys): Check for string overflow.
11481 * editfns.c (set_time_zone_rule): Don't assume environment length
11483 (message_length): Now ptrdiff_t, not int.
11484 (Fmessage_box): Don't update size until allocation succeeds.
11485 Don't assume message length fits in int.
11486 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
11488 * emacs.c (main): Do not reallocate argv, since there is a null at
11489 the end that can be overwritten, and this way there's no need to
11490 worry about size-calculation overflow.
11491 (sort_args): Check for size-calculation overflow.
11493 * eval.c (init_eval_once, grow_specpdl): Don't update size until
11495 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
11497 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
11498 (x_set_scroll_bar_width, x_figure_window_size):
11499 Check for integer overflow.
11500 (x_set_alpha): Do not assume XINT fits in int.
11502 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
11503 This is for the members text_lines, text_cols, total_lines, total_cols,
11504 where the system imposes an 'int' limit.
11506 * fringe.c (Fdefine_fringe_bitmap):
11507 Don't update size until alloc works.
11509 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
11510 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
11512 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
11513 Check for size-calculation overflow.
11514 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
11515 do, as we prefer signed integers.
11516 (id_to_widget.max_size, id_to_widget.used)
11517 (xg_store_widget_in_map, xg_remove_widget_from_map)
11518 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
11519 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
11520 Use and return ptrdiff_t, not int.
11521 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
11522 * gtkutil.h: Change prototypes to match the above.
11524 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
11525 are duplicate now that they've been promoted to lisp.h.
11526 (x_allocate_bitmap_record, x_alloc_image_color)
11527 (make_image_cache, cache_image, xpm_load):
11528 Don't update size until alloc is done.

11538 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
11539 Use ptrdiff_t, not int, to count maps.

11541 calculations. Don't update size until allocation succeeds.
11542 Redo calculations to avoid overflow.

11571 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
11572 for command line length. Do not attempt to address one before the
11573 beginning of an array, as that's not portable.
11575 * term.c (max_frame_lines): Remove; unused.
11576 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
11578 (encode_terminal_code, calculate_costs): Check for size
11579 calculation overflow.

11601 Use ptrdiff_t, not int, for sizes.
11602 (Finternal_make_lisp_face, cache_face):
11603 Check for size calculation overflow.
11604 (cache_face): Treat size calculation overflows as if they were
11605 memory exhaustion (the usual treatment), rather than aborting.
11607 * xfns.c (x_encode_text, x_set_name_internal)
11608 (Fx_change_window_property): Use ptrdiff_t, not int, to count
11609 sizes, since they can exceed INT_MAX in size. Check for size
11610 calculation overflow.
11612 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
11613 (xg_select): Check for size calculation overflow.
11614 Don't update size until alloc done.
11616 * xrdb.c (get_environ_db): Don't assume path length fits in int,
11617 as sprintf is limited to int lengths.
11619 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
11620 (X_LONG_MIN): New macros.
11621 Use them to make the following changes clearer.
11622 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
11623 This change doesn't affect the value now, but it may help remind
11624 future maintainers not to raise the value too much later.
11625 (SELECTION_QUANTUM): Remove, replacing with ...
11626 (selection_quantum): ... new function, which avoids overflow.
11628 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
11629 assumption that selection length fits in 'int'.
11630 (x_reply_selection_request, x_handle_selection_request)
11631 (x_get_window_property, receive_incremental_selection)

11635 (x_reply_selection_request, x_get_window_property)
11636 (receive_incremental_selection, x_property_data_to_lisp):
11637 Redo calculations to avoid overflow.
11638 (x_reply_selection_request): When sending hint, ceiling it at
11639 X_LONG_MAX rather than relying on wraparound overflow to send
11641 (x_get_window_property, receive_incremental_selection)
11642 (lisp_data_to_selection_data, x_property_data_to_lisp):
11643 Check for size-calculation overflow.
11644 (x_get_window_property, receive_incremental_selection)
11645 (lisp_data_to_selection_data, Fx_register_dnd_atom):
11646 Don't store size until memory allocation succeeds.
11647 (x_get_window_property): Plug memory leak on memory exhaustion.
11648 Don't double-block input; malloc is safe here. Don't assume 2**34
11649 - 4 fits in unsigned long. Add an xassert to check
11650 XGetWindowProperty overflow. Be more careful about overflow
11651 calculations, and distinguish size from memory overflow better.
11652 (receive_incremental_selection): When tracing, don't assume
11653 unsigned int is less than INT_MAX.
11654 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
11655 harmful) conversions of unsigned short to int.
11656 (lisp_data_to_selection_data): Don't assume that integers
11657 in the range -65535 through -1 fit in an X unsigned short.
11658 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
11659 result parameters unless successful. Rely on cons_to_unsigned
11660 to report problems with elements; the old code wasn't right anyway.
11661 (x_check_property_data): Check for int overflow; we cannot use
11662 a wider type due to X limits.
11663 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

11667 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
11668 (x_term_init): Check for size calculation overflow.
11669 (x_color_cells): Don't store size until memory allocation succeeds.
11670 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
11671 Don't assume alloca size is less than MAX_ALLOCA.
11672 (x_term_init): Don't assume length fits in int (sprintf is limited
11675 Use ptrdiff_t for composition IDs.
11676 * character.c (lisp_string_width):
11677 * composite.c (composition_table_size, n_compositions)
11678 (get_composition_id, composition_gstring_from_id):

11694 * image.c (xpm_get_color_table_h):
11695 * lisp.h (hash_lookup, hash_put):
11696 * minibuf.c (Ftest_completion):
11697 Use ptrdiff_t for hash table indexes, not int (which is too
11698 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
11699 32-bit --with-wide-int hosts).
11701 * charset.c (Fdefine_charset_internal): Check for integer overflow.
11702 Add a FIXME comment about memory leaks.
11703 (syms_of_charset): Don't assume xmalloc returns.
11705 Don't assume that stated character widths fit in int.

11707 * character.h (CHAR_WIDTH):
11708 * indent.c (MULTIBYTE_BYTES_WIDTH):
11709 Use sanitize_char_width to avoid undefined and/or bad behavior
11710 with outlandish widths.
11711 * character.h (sanitize_tab_width): Rename from sanitize_width,
11712 now that we have two such functions. All uses changed.

11723 * fileio.c: Integer overflow issues with file modes.
11724 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
11726 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
11727 Remove unreachable code.
11728 (read_hex, load_charset_map_from_file): Check for integer overflow.
11730 * xterm.c: Don't go over XClientMessageEvent limit.
11731 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
11732 (x_send_scroll_bar_event): Likewise. Check that the size does not
11733 exceed limits imposed by XClientMessageEvent, as well as the usual
11734 ptrdiff_t and size_t limits.
11736 * keyboard.c: Overflow, signedness and related fixes.
11737 (make_lispy_movement): Use same integer type in forward decl
11738 that is used in the definition.
11739 (read_key_sequence, keyremap_step):
11740 Change bufsize argument back to int, undoing my 2011-03-30 change.
11741 We prefer signed types, and int is wide enough here.
11742 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
11743 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
11744 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
11745 length, not size_t. Use ptrdiff_t for index, not int.
11746 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
11747 possibility of integer overflow.
11749 Overflow, signedness and related fixes for images.
11751 * dispextern.h (struct it.stack[0].u.image.image_id)

11759 * xdisp.c (calc_pixel_width_or_height):
11760 * xfns.c (image_cache_refcount):
11761 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
11762 on typical 64-bit hosts.

11770 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
11771 (lookup_image): Remove unnecessary tests.
11772 (xbm_image_p): Locals are now of int, not EMACS_INT,
11773 since parse_image_check makes sure they fit into int.
11774 (png_load, gif_load, svg_load_image):
11775 Prefer int to unsigned where either will do.
11776 (tiff_handler): New function, combining the cores of the
11777 old tiff_error_handler and tiff_warning_handler.
11778 This function is rewritten to use vsnprintf and thereby avoid
11779 stack buffer overflows. It uses only the features of vsnprintf
11780 that are common to both POSIX and native Microsoft.
11781 (tiff_error_handler, tiff_warning_handler): Use it.
11782 (tiff_load, gif_load, imagemagick_load_image):
11783 Don't assume :index value fits in 'int'.
11784 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
11785 (imagemagick_load_image): Check that crop parameters fit into
11786 the integer types that MagickCropImage accepts. Don't assume
11787 Vimagemagick_render_type has a nonnegative value. Don't assume
11788 size_t fits in 'long'.
11789 (gs_load): Use printmax_t to print the widest integers possible.
11790 Check for integer overflow when computing image height and width.
11792 2011-08-26 Eli Zaretskii <eliz@gnu.org>
11794 * xdisp.c (redisplay_window): Don't force window start if point

11799 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
11800 the display spec is of the form `(space ...)'.
11801 (handle_display_spec): Return the value returned by
11802 handle_single_display_spec, not just 1 or zero.
11803 (handle_single_display_spec): If the display spec is of the form
11804 `(space ...)', and specifies display in the text area, return 2
11806 (try_cursor_movement): Check for the need to scroll more
11807 accurately, and prefer exact match for point under bidi.
11808 Don't advance `row' beyond the last row of the window.
11810 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
11811 into disp_prop; all users changed.
11813 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
11814 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
11815 for the text covered by the display property.

11825 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
11826 buffers, return left-to-right.
11827 (set_cursor_from_row): Consider candidate row a win if its glyph
11828 represents a newline and point is on that newline. Fixes cursor
11829 positioning on the newline at EOL of R2L text within L2R
11830 paragraph, and vice versa.
11831 (try_cursor_movement): Check continued rows, in addition to
11832 continuation rows. Fixes unwarranted scroll when point enters a
11833 continued line of R2L text within an L2R paragraph, or vice versa.
11834 (cursor_row_p): Consider the case of point being equal to
11835 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
11836 from the end of a short line to the beginning of a continued line
11837 of R2L text within L2R paragraph.
11838 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
11839 composed characters.

11854 2011-08-22 Kenichi Handa <handa@m17n.org>
11856 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
11857 extra slot even if the purpose is char-code-property-table.
11859 2011-08-23 Eli Zaretskii <eliz@gnu.org>
11861 * xdisp.c (redisplay_window): When computing centering_position,
11862 account for the height of the header line. (Bug#8874)
11864 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
11865 instead of CHAR_TO_BYTE. Fixes a crash when a completion
11866 candidate is selected by the mouse, and that candidate has a
11867 composed character under the mouse.
11869 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
11870 coordinates reported by pos-visible-in-window-p for a composed
11871 character in column zero.
11873 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
11875 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
11877 2011-08-22 Eli Zaretskii <eliz@gnu.org>
11879 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
11880 consider it a hit if to_charpos is anywhere in the range of the
11881 composed buffer positions.
11883 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
11885 * image.c (gif_load): Don't assume that each subimage has the same
11886 dimensions as the base image. Handle disposal method that is
11887 "undefined" by the gif spec (Bug#9335).
11889 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
11891 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
11892 (Fcondition_case): Document `debug' symbol in error handler.
11894 2011-08-19 Eli Zaretskii <eliz@gnu.org>
11896 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
11897 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
11898 from an Org mode buffer to a Speedbar frame.
11900 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
11901 a composition, take its buffer position from IT->cmp_it.charpos.
11902 Fixes cursor positioning at the beginning of a line that begins
11903 with a composed character.
11905 2011-08-18 Eli Zaretskii <eliz@gnu.org>
11907 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
11908 character bidirectional type, use STRONG_L instead. Fixes crashes
11909 in a buffer produced by `describe-categories'.
11911 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
11912 members before the level stack, so they would be saved and
11913 restored when copying iterator state. Fixes incorrect reordering
11914 around TABs covered by display properties.
11916 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
11918 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

11922 * eval.c (internal_condition_case, internal_condition_case_1)
11923 (internal_condition_case_2, internal_condition_case_n):
11924 Remove unnecessary aborts (Bug#9081).
11926 2011-08-17 Eli Zaretskii <eliz@gnu.org>
11928 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
11929 has no `load' handler, try opening the file locally. (Bug#9311)
11931 2011-08-16 Ken Brown <kbrown@cornell.edu>
11933 * gmalloc.c: Expand comment.
11935 2011-08-16 Eli Zaretskii <eliz@gnu.org>
11937 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
11938 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
11940 2011-08-16 Ken Brown <kbrown@cornell.edu>
11942 Fix memory allocation problems in Cygwin build (Bug#9273).
11944 * unexcw.c ( __malloc_initialized): Declare external variable.
11945 (fixup_executable): Force the dumped emacs to reinitialize malloc.
11947 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):

11977 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
11978 coordinates of the iterator when restoring from ppos_it.
11981 2011-08-14 Kenichi Handa <handa@m17n.org>
11983 * process.c (create_process): Call setup_process_coding_systems
11984 after the pid of the process is set to -1 (Bug#8162).
11986 2011-08-14 Eli Zaretskii <eliz@gnu.org>
11988 * xdisp.c (move_it_in_display_line_to): Don't invoke
11989 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
11990 ppos_it. Fixes vertical cursor motion when line beginning is
11991 covered by an image. (Bug#9296)
11993 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
11995 * nsterm.h (ns_run_ascript): Declare.

11999 (ns_run_ascript): New function.
12000 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
12001 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
12002 the event loop. Get status from as_status (Bug#7276).
12004 * nsterm.m (sendEvent): If event is NSApplicationDefined and
12005 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
12006 the event loop (Bug#7276).
12008 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
12010 * gnutls.c (QCgnutls_bootprop_priority)

12031 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
12032 (Fnetwork_interface_list): Allocate in increments of bytes instead
12033 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
12034 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
12036 (struct ifflag_def): notrailers is smart on OSX.
12037 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
12038 Get hardware address with getifaddrs if available.
12040 2011-08-12 Eli Zaretskii <eliz@gnu.org>
12042 * xdisp.c (iterate_out_of_display_property): xassert that
12043 IT->position is set to within IT->object's boundaries. Break from
12044 the loop as soon as EOB is reached; avoids infloops in redisplay
12045 when IT->position is set up wrongly due to some bug.
12046 Set IT->current to match the bidi iterator unconditionally.
12047 (push_display_prop): Allow GET_FROM_STRING as IT->method on
12048 entry. Force push_it to save on the stack the current
12049 buffer/string position, to be restored by pop_it. Fix flags in
12050 the iterator structure wrt the object coming from a display
12051 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
12052 properties. (Bug#9284)
12054 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
12056 * fontset.c (fontset_get_font_group): Add proper type checks.

12064 (dump_it) [LC_FUNCTION_STARTS]: Use it.
12066 2011-08-08 Eli Zaretskii <eliz@gnu.org>
12068 * xdisp.c (forward_to_next_line_start): Allow to use the
12069 no-display-properties-and-no-overlays under bidi display.
12070 Set disp_pos in the bidi iterator to avoid searches for display
12071 properties and overlays.
12073 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
12075 * editfns.c (Fset_time_zone_rule): Document relationship with the
12078 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
12079 the font entity extracted from the cache (Bug#8109).
12081 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
12083 * composite.c (autocmp_chars): Don't reset point. That is done by
12084 restore_point_unwind (Bug#5984).
12086 2011-08-07 Juri Linkov <juri@jurta.org>
12088 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
12089 to show the arg `TIME' instead of `TIMEVAL'.
12091 2011-08-06 Eli Zaretskii <eliz@gnu.org>
12093 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
12094 display property strides EOL and includes a newline, as in
12095 longlines-mode. (Bug#9254)
12096 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
12097 word-wrap under bidirectional display. (Bug#9224)
12099 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
12100 is non-zero, even if the data buffer is NULL. Fixes a crash in
12101 vertical-motion with longlines-mode. (Bug#9254)
12103 2011-08-05 Eli Zaretskii <eliz@gnu.org>
12105 * bidi.c <bidi_cache_total_alloc>: Now static.
12106 (bidi_initialize): Initialize bidi_cache_total_alloc.
12108 * xdisp.c (display_line): Release buffer allocated for shelved bidi
12111 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
12112 amount allocated this far in `bidi_cache_total_alloc'.
12113 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
12114 non-zero, only free the data buffer without restoring the cache
12115 contents. All callers changed.
12117 * dispextern.h (bidi_unshelve_cache): Update prototype.
12119 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
12120 (move_it_in_display_line, move_it_to)
12121 (move_it_vertically_backward, move_it_by_lines): Replace the call
12122 to xfree to an equivalent call to bidi_unshelve_cache.
12123 (move_it_in_display_line_to): Fix logic of returning
12124 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
12126 2011-08-05 Eli Zaretskii <eliz@gnu.org>
12128 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
12129 came from a string character with a `cursor' property. (Bug#9229)
12131 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
12133 * Makefile.in (LIB_PTHREAD): New variable.
12134 (LIBES): Add LIB_PTHREAD (Bug#9216).
12136 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
12137 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
12139 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
12141 * regex.c (re_iswctype): Remove some redundant boolean conversions.
12143 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
12145 * xterm.c (x_find_topmost_parent): New function.
12146 (x_set_frame_alpha): Find topmost parent window with
12147 x_find_topmost_parent and set the property there also (bug#9181).
12148 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
12150 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
12152 * callproc.c (Fcall_process): Avoid vfork clobbering
12153 the local vars buffer, coding_systems, current_dir.
12155 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
12157 * keymap.c (Fmake_composed_keymap): Move to subr.el.
12159 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
12161 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
12162 so that it is not optimized away.
12164 * xdisp.c (compute_display_string_pos): Remove unused local.
12166 2011-08-02 Eli Zaretskii <eliz@gnu.org>
12168 Fix slow cursor motion and scrolling in large buffers with
12169 selective display, like Org Mode buffers. (Bug#9218)
12171 * dispextern.h (struct bidi_it): New member disp_prop_p.
12173 * xdisp.c: Remove one-slot cache of display string positions.
12174 (compute_display_string_pos): Accept an additional argument
12175 DISP_PROP_P; callers changed. Scan at most 5K characters forward
12176 for a display string or property. If found, set DISP_PROP_P
12179 * bidi.c (bidi_fetch_char): Accept an additional argument
12180 DISP_PROP_P, and pass it to compute_display_string_pos.
12181 Only handle text covered by a display string if DISP_PROP_P is returned
12182 non-zero. All callers of bidi_fetch_char changed.
12184 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
12186 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
12188 2010-12-03 Don March <don@ohspite.net>
12190 * keymap.c (Fdefine_key): Fix non-prefix key error message when
12191 last character M-[char] is translated to ESC [char] (bug#7541).
12193 2011-08-02 Kenichi Handa <handa@m17n.org>
12195 * lisp.h (uniprop_table): Extern it.
12197 * chartab.c (uniprop_table): Make it non-static.
12199 2011-08-01 Eli Zaretskii <eliz@gnu.org>
12201 * xdisp.c (forward_to_next_line_start): Accept additional argument
12202 BIDI_IT_PREV, and store into it the state of the bidi iterator had
12204 (reseat_at_next_visible_line_start): Use the bidi iterator state
12205 returned by forward_to_next_line_start to restore the state of
12206 it->bidi_it after backing up to previous newline. (Bug#9212)
12208 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
12210 * regex.c (re_comp): Protoize.
12211 (re_exec): Fix return type.
12212 (regexec): Fix type of `ret'. (Bug#9203)
12214 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12216 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
12217 This is needed if max-image-size is a floating-point number.
12219 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
12221 * print.c (print_object): Print empty symbol as ##.
12223 * lread.c (read1): Read ## as empty symbol.
12225 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
12227 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
12228 setting frame foreground color (Bug#9175).
12229 (x_set_background_color): Likewise.
12231 * nsmenu.m (-setText): Size tooltip dimensions precisely to
12232 contents (Bug#9176).
12233 (EmacsTooltip -init): Remove bezels and add shadows to
12236 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
12237 or scroll bar (Bug#8470).
12239 * nsfont.m (nsfont_open): Remove assignment to voffset and
12240 unnecessary vars hshink, expand, hd, full_height, min_height.
12241 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
12243 * nsterm.h (nsfont_info): Remove voffset field.
12245 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
12247 Implement strike-through and overline on NextStep (Bug#8863).
12249 * nsfont.m (nsfont_open): Use underline position provided by font,
12250 instead of hard-coded value of 2.
12251 (nsfont_draw): Call ns_draw_text_decoration instead.
12253 * nsterm.h: Add declaration for ns_draw_text_decoration.
12255 * nsterm.m (ns_draw_text_decoration): New function for drawing
12256 underline, overline, and strike-through.
12257 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
12258 ns_draw_text_decoration. Change treatment of cursor drawing to
12259 accommodate underlining, etc.
12261 2011-07-28 Eli Zaretskii <eliz@gnu.org>
12263 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
12266 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12268 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
12269 Without this fix, if a signal arrives just after memory fills up,
12270 'malloc' might be invoked reentrantly.
12272 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
12273 In other words, assume that every image size is allowed, on non-X
12274 hosts. This assumption is probably wrong, but it lets Emacs compile.
12276 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
12278 * regex.c (re_iswctype): Convert return values to boolean.
12280 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
12282 * xdisp.c (compute_display_string_pos): Don't use cached display
12283 string position if the buffer had its restriction changed.
12286 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12288 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12290 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12292 Integer signedness and overflow and related fixes. (Bug#9079)
12294 * bidi.c: Integer size and overflow fixes.
12295 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
12296 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
12297 (bidi_cache_find_level_change, bidi_cache_ensure_space)
12298 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
12299 (bidi_find_other_level_edge):
12300 Use ptrdiff_t instead of EMACS_INT where either will do.
12301 This works better on 32-bit hosts configured --with-wide-int.
12302 (bidi_cache_ensure_space): Check for size-calculation overflow.
12303 Use % rather than repeated addition, for better worst-case speed.
12304 Don't set bidi_cache_size until after xrealloc returns, because it
12306 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
12307 (bidi_cache_ensure_space): Also check that the bidi cache size
12308 does not exceed that of the largest Lisp string or buffer. See Eli
12309 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
12311 * alloc.c (__malloc_size_t): Remove.
12312 All uses replaced by size_t. See Andreas Schwab's note
12313 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
12315 * image.c: Improve checking for integer overflow.
12316 (check_image_size): Assume that f is nonnull, since
12317 it is always nonnull in practice. This is one less thing to
12318 worry about when checking for integer overflow later.
12319 (x_check_image_size): New function, which checks for integer
12320 overflow issues inside X.
12321 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
12322 This removes the need for a memory_full check.
12323 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
12324 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
12325 (xbm_read_bitmap_data): Change locals back to 'int', since
12326 their values must fit in 'int'.
12327 (xpm_load_image, png_load, tiff_load):
12328 Invoke x_create_x_image_and_pixmap earlier,
12329 to avoid much needless work if the image is too large.
12330 (tiff_load): Treat overly large images as if
12331 x_create_x_image_and_pixmap failed, not as malloc failures.
12332 (gs_load): Use x_check_image_size.
12334 * gtkutil.c: Omit integer casts.
12335 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
12336 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
12338 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
12340 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
12341 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
12342 would wrongly return t on a 64-bit host.
12344 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
12345 The plain *_OVERFLOW macros run afoul of GCC bug 49705
12346 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
12347 and therefore cause GCC to emit a bogus diagnostic in some cases.
12349 * image.c: Integer signedness and overflow and related fixes.
12350 This is not an exhaustive set of fixes, but it's time to
12351 record what I've got.
12352 (lookup_pixel_color, check_image_size): Remove redundant decls.
12353 (check_image_size): Don't assume that arbitrary EMACS_INT values
12354 fit in 'int', or that arbitrary 'double' values fit in 'int'.
12355 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
12356 (tiff_load, imagemagick_load_image):
12357 Check for overflow in size calculations.
12358 (x_create_x_image_and_pixmap): Remove unnecessary test for
12359 xmalloc returning NULL; that can't happen.
12360 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
12361 (xpm_color_bucket): Use better integer hashing function.
12362 (xpm_cache_color): Don't possibly over-allocate memory.
12363 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
12364 (gif_memory_source):
12365 Use ptrdiff_t, not int or size_t, to record sizes.
12366 (png_load): Don't assume values greater than 2**31 fit in 'int'.
12367 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
12368 either works, as we prefer signed integers.
12369 (tiff_read_from_memory, tiff_write_from_memory):
12370 Return tsize_t, not size_t, since that's what the TIFF API wants.
12371 (tiff_read_from_memory): Don't fail simply because the read would
12372 go past EOF; instead, return a short read.
12373 (tiff_load): Omit no-longer-needed casts.
12374 (Fimagemagick_types): Don't assume size fits into 'int'.
12376 Improve hashing quality when configured --with-wide-int.
12377 * fns.c (hash_string): New function, taken from sxhash_string.
12378 Do not discard information about ASCII character case; this
12379 discarding is no longer needed.
12380 (sxhash-string): Use it. Change sig to match it. Caller changed.
12381 * lisp.h: Declare it.
12382 * lread.c (hash_string): Remove, since we now use fns.c's version.
12383 The fns.c version returns a wider integer if --with-wide-int is
12384 specified, so this should help the quality of the hashing a bit.
12386 * emacs.c: Integer overflow minor fix.
12387 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
12388 Define only if GNU_LINUX.
12389 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
12391 * dispnew.c: Integer signedness and overflow fixes.
12392 Remove unnecessary forward decls, that were a maintenance hassle.
12393 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
12395 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
12396 (scrolling_window): Use ptrdiff_t, not int, for byte count.
12397 (prepare_desired_row, line_draw_cost):
12398 Use int, not unsigned, where either works.
12399 (save_current_matrix, restore_current_matrix):
12400 Use ptrdiff_t, not size_t, where either works.
12401 (init_display): Check for overflow more accurately, and without
12402 relying on undefined behavior.
12404 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
12405 Remove, replacing with the new symbols in lisp.h. All uses changed.
12406 * fileio.c (make_temp_name):
12407 * filelock.c (lock_file_1, lock_file):
12408 * xdisp.c (message_dolog):
12409 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
12410 Use pMd etc. instead.
12411 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
12412 replacing the pWIDE etc. symbols removed from editfns.c.
12414 * keyboard.h (num_input_events): Now uintmax_t.
12415 This is (very slightly) less likely to mess up due to wraparound.
12418 * buffer.c: Integer signedness fixes.
12419 (alloc_buffer_text, enlarge_buffer_text):
12420 Use ptrdiff_t rather than size_t when either will do, as we prefer
12423 * alloc.c: Integer signedness and overflow fixes.
12424 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
12425 (__malloc_size_t): Default to size_t, not to int.
12426 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
12427 (Fgarbage_collect, mark_object_loop_halt, mark_object):
12428 Prefer ptrdiff_t to size_t when either would do, as we prefer
12430 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
12431 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
12432 Now const. Initialize with values that are in range even if char
12434 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
12435 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
12436 These functions do the right thing with sizes > 2**32.
12437 (check_depth): Now ptrdiff_t, not int.
12438 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
12439 Adjust to new way of storing sizes. Check for size overflow bugs
12441 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
12442 slightly wrong anyway, as it missed one instance of
12443 XMALLOC_OVERRUN_CHECK_OVERHEAD.
12444 (refill_memory_reserve): Omit needless cast to size_t.
12445 (mark_object_loop_halt): Mark as externally visible.
12447 * xselect.c: Integer signedness and overflow fixes.
12448 (Fx_register_dnd_atom, x_handle_dnd_message):
12449 Use ptrdiff_t, not size_t, since we prefer signed.
12450 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
12451 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
12452 x_dnd_atoms_size and x_dnd_atoms_length.
12454 * doprnt.c: Prefer signed to unsigned when either works.
12456 * doprnt.c (doprnt):
12458 * xdisp.c (vmessage):
12459 Use ptrdiff_t, not size_t, when using or implementing doprnt,
12460 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
12461 prefer signed arithmetic to avoid comparison confusion.
12462 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
12463 but is a bit tricky.
12465 Assume freestanding C89 headers, string.h, stdlib.h.
12466 * data.c, doprnt.c, floatfns.c, print.c:
12467 Include float.h unconditionally.
12468 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
12469 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
12470 * regex.c: Likewise for stddef.h, string.h.
12471 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
12472 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
12473 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
12474 (STDC_HEADERS): Remove obsolete defines.
12475 * sysdep.c: Include limits.h unconditionally.
12477 Assume support for memcmp, memcpy, memmove, memset.
12478 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
12479 * regex.c (memcmp, memcpy):
12480 Remove; we assume C89 now.
12482 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
12483 (__malloc_safe_bcopy): Remove; no longer needed.
12485 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
12486 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
12487 well either way, and we prefer signed to unsigned.
12489 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
12491 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
12492 closes the connection while we're reading (bug#9182).
12494 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
12496 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
12497 are specified (Bug#9168).
12499 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
12501 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
12502 Found by GCC static checking and --with-wide-int on a 32-bit host.
12504 2011-07-25 Eli Zaretskii <eliz@gnu.org>
12506 * xdisp.c (compute_display_string_pos): Fix logic of caching
12507 previous display string position. Initialize cached_prev_pos to
12508 -1. Fixes slow-down at the beginning of a buffer.
12510 2011-07-24 Eli Zaretskii <eliz@gnu.org>
12512 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
12513 for attrs[LFACE_FONTSET_INDEX].
12515 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
12517 * xml.c (parse_region): Remove unused local
12518 that was recently introduced.
12520 2011-07-23 Eli Zaretskii <eliz@gnu.org>
12522 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
12523 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
12525 * xdisp.c (move_it_in_display_line_to): Record the best matching
12526 position for TO_CHARPOS while scanning the line, and restore it on
12527 exit if none of the characters scanned was an exact match.
12528 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
12529 when exact match is impossible due to invisible text, and the
12530 lines are truncated.
12532 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
12534 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
12537 2011-07-22 Eli Zaretskii <eliz@gnu.org>
12539 Fix a significant slow-down of cursor motion with C-n, C-p,
12540 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
12541 auto-repeat under bidi redisplay in fontified buffers.
12542 * xdisp.c (compute_stop_pos_backwards): New function.
12543 (next_element_from_buffer): Call compute_stop_pos_backwards to
12544 find a suitable prev_stop when we find ourselves before
12546 (reseat): Don't look for prev_stop, as that could mean a very long
12548 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
12549 <cached_disp_overlay_modiff>: Cache for last found display string
12551 (compute_display_string_pos): Return the cached position if asked
12552 about the same buffer in the same area of character positions, and
12553 the buffer wasn't changed since the time the display string
12554 position was cached.
12556 2011-07-22 Eli Zaretskii <eliz@gnu.org>
12558 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
12559 is an integer, which is important for empty lines. (Bug#9149)
12561 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
12563 * frame.c (Fmodify_frame_parameters): In tty case, update the
12564 default face if necessary (Bug#4238).
12566 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
12568 * editfns.c (Fstring_to_char): No need to explain what a character
12569 is in the docstring (Bug#6576).
12571 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
12573 * xml.c (parse_region): Make sure we always return a tree.
12575 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
12577 * xml.c (parse_region): If a document contains only comments,
12580 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
12582 * xml.c (make_dom): Return comments, too.
12584 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
12587 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
12588 and the surrounding thread.
12589 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
12590 rather than fgets, and retry after EINTR. Otherwise, 'emacs
12591 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
12593 * s/openbsd.h (BROKEN_SIGIO): Define.
12594 * unexelf.c (unexec) [__OpenBSD__]:
12595 Don't update the .mdebug section of the Alpha COFF symbol table.
12597 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12599 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
12602 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
12604 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
12605 This fixes some race conditions on the permissions of any newly
12608 * alloc.c (valid_pointer_p): Use pipe, not open.
12609 This fixes some permissions issues when debugging.
12611 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
12612 If fchown fails to set both uid and gid, try to set just gid,
12613 as that is sometimes allowed. Adjust the file's mode to eliminate
12614 setuid or setgid bits that are inappropriate if fchown fails.
12616 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
12618 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
12619 to compare Lisp_Objects.

12622 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
12624 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
12626 * lread.c (read_integer): Unread even EOF character.
12627 (read1): Likewise. Properly record start position of symbol.
12629 * lread.c (read1): Read `#:' as empty uninterned symbol if no
12630 symbol character follows.
12632 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
12634 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
12635 This works around a problem with the previous change to Fcopy_file.
12636 Recent glibc declares fchown with __attribute__((warn_unused_result)),
12637 and without this change, GCC might complain about discarding
12638 fchown's return value.
12640 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
12642 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
12644 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
12646 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
12648 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
12650 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
12651 it's used from the C level.
12653 * process.c: Use the same condition for POLL_FOR_INPUT in both
12654 keyboard.c and process.c (bug#1858).
12656 2011-07-09 Lawrence Mitchell <wence@gmx.li>
12658 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
12659 (Fgnutls_boot): Use it.
12661 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
12663 * doc.c (Fsubstitute_command_keys): Revert last change.
12665 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
12667 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
12668 quotes the next character, and doesn't affect other longer
12669 sequences (bug#8935).
12671 * lread.c (syms_of_lread): Clarify that is isn't only
12672 `eval-buffer' and `eval-defun' that's affected by
12673 `lexical-binding' (bug#8460).
12675 2011-07-15 Eli Zaretskii <eliz@gnu.org>
12677 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
12678 bidi redisplay when a line includes both an image and is truncated.
12680 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
12682 Fix minor problems found by static checking.
12683 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
12684 (elsz): Now a signed constant, not a size_t var. We prefer signed
12685 types to unsigned, to avoid integer comparison confusion. Without
12686 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
12687 "cannot optimize loop, the loop counter may overflow", a symptom
12689 * indent.c (Fvertical_motion): Mark locals as initialized.
12690 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
12692 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
12694 * search.c (Fre_search_backward): Mention `case-fold-search' in
12695 all the re_search_* functions (bug#8138).

12710 bidi_it->string.schars.
12711 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to

12715 buffer position was specified. Initialize paragraph_embedding to
12717 (reseat_to_string): Initialize the bidi iterator.
12718 (display_string): If we need to ignore text properties of
12719 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
12720 original value of -1 will not work with bidi.)
12721 (compute_display_string_pos): First arg is now struct
12722 `text_pos *'; all callers changed. Support display properties on
12724 (compute_display_string_end): Support display properties on Lisp
12726 (init_iterator, reseat_1, reseat_to_string): Initialize the
12727 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
12728 when iterating on a string not from display properties).
12729 (compute_display_string_pos, compute_display_string_end):
12730 Fix calculation of the object to scan. Fixes an error when using
12732 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
12733 base_level_stop; instead, set base_level_stop to BEGV.
12734 Fixes crashes in vertical-motion.
12735 (next_element_from_buffer): Improve commentary for when
12736 the iterator is before prev_stop.
12737 (init_iterator): Initialize bidi_p from the default value of
12738 bidi-display-reordering, not from buffer-local value. Use the
12739 buffer-local value only if initializing for buffer iteration.
12740 (handle_invisible_prop): Support invisible properties on strings
12741 that are being bidi-reordered.
12742 (set_iterator_to_next): Support bidi reordering of C strings and

12748 Use IT_STRING_CHARPOS when displaying from a Lisp string.
12749 (init_iterator): Don't initialize it->bidi_p for strings
12751 (reseat_to_string): Initialize it->bidi_p for strings here.

12758 character that is not the first one in the visual order.
12759 (get_visually_first_element): New function, refactored from common
12760 parts of next_element_from_buffer, next_element_from_string, and
12761 next_element_from_c_string.
12762 (tool_bar_lines_needed, redisplay_tool_bar)
12763 (display_menu_bar): Force left-to-right direction. Add a FIXME
12764 comment for making that be controlled by a user option.
12765 (push_it, pop_it): Save and restore the state of the
12766 bidi iterator. Save and restore the bidi_p flag.

12770 (handle_single_display_spec): Set up it->bidi_it for iteration
12771 over a display string, and call bidi_init_it.

12773 (get_overlay_strings_1, push_display_prop): Set up the bidi
12774 iterator for displaying display or overlay strings.
12775 (forward_to_next_line_start): Don't use the shortcut if
12777 (back_to_previous_visible_line_start): If handle_display_prop
12778 pushed the iterator stack, restore the internal state of the bidi
12779 iterator by calling bidi_pop_it same number of times.
12780 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
12781 and we are bidi-iterating, don't decrement the iterator position;
12782 instead, set the first_elt flag in the bidi iterator, to produce
12784 (reseat_1): Remove redundant setting of string_from_display_prop_p.
12785 (push_display_prop): xassert that we are iterating a buffer.
12786 (push_it, pop_it): Save and restore paragraph_embedding member.
12787 (handle_single_display_spec, next_overlay_string)
12788 (get_overlay_strings_1, reseat_1, reseat_to_string)
12789 (push_display_prop): Set up the `unibyte' member of bidi_it.string
12790 correctly. Don't assume unibyte strings are not bidi-reordered.
12791 (compute_display_string_pos)
12792 (compute_display_string_end): Fix handling the case of C string.
12793 (push_it, pop_it): Save and restore from_disp_prop_p.

12797 (pop_it): Call iterate_out_of_display_property only if we are
12798 popping after iteration over a string that came from a display
12799 property. Fix a typo in popping stretch info. Add an assertion
12800 for verifying that the iterator position is in sync with the bidi
12802 (handle_single_display_spec, get_overlay_strings_1)
12803 (push_display_prop): Fix initialization of paragraph direction for
12804 string when that of the parent object is not yet determined.

12816 (try_scrolling, redisplay_window, display_line): Use them when
12817 saving a temporary copy of the iterator and restoring it back.
12818 (back_to_previous_visible_line_start, reseat_1)
12819 (init_iterator): Empty the bidi cache "stack".
12820 (move_it_in_display_line_to): If iterator ended up at
12821 EOL, but we never saw any buffer positions smaller than
12822 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
12823 motion in bidi-reordered lines.

12825 immediately before the call to set_iterator_to_next. Fixes cursor
12826 motion in bidi-reordered lines with stretch glyphs and strings
12827 displayed in margins. (Bug#8133) (Bug#8867)
12828 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
12830 (pos_visible_p): Support positions in bidi-reordered lines.
12831 Save and restore bidi cache.
12833 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
12834 (bidi_paragraph_info): Delete unused struct.
12835 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
12836 (bidi_cache_start): New variable.
12837 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not

12854 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
12855 can now be zero (for strings); special values 0 and -1 were
12856 changed to -1 and -2, respectively.
12857 (bidi_char_at_pos): New function.
12858 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

12869 (bidi_initialize): Initialize the bidi cache start stack pointer.
12870 (bidi_cache_ensure_space): New function, refactored from part of

12886 * dispextern.h (struct bidi_string_data): New structure.
12887 (struct bidi_it): New member `string'. Make flag members be 1-bit
12888 fields, and put them last in the struct.
12889 (compute_display_string_pos, compute_display_string_end):
12891 (bidi_push_it, bidi_pop_it): Add prototypes.
12892 (struct iterator_stack_entry): New members bidi_p,
12893 paragraph_embedding, and from_disp_prop_p.
12894 (struct it): Member bidi_p is now a bit field 1 bit wide.
12895 (bidi_shelve_cache, bidi_unshelve_cache):
12896 Declare prototypes.
12898 * .gdbinit (xvectype, xvector, xcompiled, xchartable, xboolvector)

12941 Pass Qx_lost_selection_functions rather than
12942 Vx_lost_selection_functions to Frun_hook_with_args.
12944 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
12946 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
12947 The old code sometimes used this field without initializing it.
12949 * alloc.c (gc_sweep): Don't read past end of array.
12950 In theory, the old code could also have corrupted Emacs internals,
12951 though it'd be very unlikely.
12953 2011-07-12 Andreas Schwab <schwab@linux-m68k.org>
12955 * character.c (Fcharacterp): Don't advertise optional ignored
12956 argument. (Bug#4026)

13214 (clone_per_buffer_values): Don't assume that
13215 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
13216 This isn't true in general, and it's particularly not true
13217 if Emacs is configured with --with-wide-int.
13218 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
13219 New macros, used in the buffer.c change.

13255 Random fixes. E.g., (random) never returned negative values.
13256 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
13257 subseconds part to the entropy, as that's a bit more random.
13258 Prefer signed to unsigned, since the signedness doesn't matter and
13259 in general we prefer signed. When given a limit, use a
13260 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
13261 latter isn't right if USE_2_TAGS_FOR_INTS.
13262 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
13263 not 0..VALMASK. Don't discard "excess" bits that random () returns.
13265 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
13267 * textprop.c (text_property_stickiness):
13268 Obey Vtext_property_default_nonsticky.

13275 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
13276 This is more efficient than Ffile_directory_p and avoids a minor race.
13278 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
13280 * buffer.c (Foverlay_put): Say what the return value is
13283 * fileio.c (barf_or_query_if_file_exists): Check first if the file
13284 is a directory before asking whether to use the file name
13286 (barf_or_query_if_file_exists): Make the "File is a directory"
13287 error be more correct.
13289 * fns.c (Frequire): Remove the mention of the .gz files, since
13290 that's installation-specific, but keep the mention of
13291 `get-load-suffixes'.
13293 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
13295 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

13303 Qgnutls_bootprop_verify_error (which is no longer used).
13305 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
13306 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
13307 Also (re)move comments that are misplaced or no longer relevant.
13309 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13311 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

13329 2011-07-02 Chong Yidong <cyd@stupidchicken.com>
13331 * keyboard.c (command_loop_1): If a down-mouse event is unbound,
13332 leave any prefix arg for the up event (Bug#1586).
13334 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
13336 * lread.c (syms_of_lread): Mention single symbols defined by
13337 `defvar' or `defconst' (bug#7154).
13339 * fns.c (Frequire): Mention .el.gz files (bug#7314).
13340 (Frequire): Mention get-load-suffixes.
13342 2011-07-02 Martin Rudalics <rudalics@gmx.at>
13344 * window.h (window): Remove clone_number slot.
13345 * window.c (Fwindow_clone_number, Fset_window_clone_number):

13363 (Fcopy_keymap): Handle embedded parents.
13364 (Fcommand_remapping, define_as_prefix): Simplify.
13365 (Fkey_binding): Simplify.

13367 minibuffer-local-filename-completion-map,
13368 minibuffer-local-must-match-map, and
13369 minibuffer-local-filename-must-match-map to Elisp.
13370 (syms_of_keymap): Defsubr make-composed-keymap.
13371 * keyboard.c (menu_bar_items): Use map_keymap_canonical.
13372 (parse_menu_item): Trivial simplification.
13374 2011-07-01 Glenn Morris <rgm@gnu.org>
13376 * Makefile.in (SETTINGS_LIBS): Fix typo.

13400 (xgselect_initialize): Ditto.
13402 * process.c: Add defined (HAVE_GSETTINGS) for xgselect.h
13403 (wait_reading_process_output): Add defined (HAVE_GSETTINGS) for
13406 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
13408 * eval.c (struct backtrace): Simplify and port the data structure.
13409 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
13410 signed bit field, as this assumption is not portable and it makes
13411 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
13412 "char debug_on_exit : 1" as this is not portable either; instead,
13413 use the portable "unsigned int debug_on_exit : 1". Remove unused
13414 member evalargs. Remove obsolete comments about cc bombing out.
13416 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

13582 * print.c (printchar, strout): Check for string overflow.
13583 (PRINTPREPARE, printchar, strout):
13584 Don't set size unless allocation succeeds.
13586 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
13587 for sizes. Check for string overflow more accurately.
13588 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
13590 * macros.c: Integer and buffer overflow fixes.
13591 * keyboard.h (struct keyboard.kbd_macro_bufsize):
13592 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

13596 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
13598 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
13600 * lread.c: Integer overflow fixes.
13601 (read_integer): Radix is now EMACS_INT, not int,
13602 to improve quality of diagnostics for out-of-range radices.
13603 Calculate buffer size correctly for out-of-range radices.
13604 (read1): Check for integer overflow in radices, and in
13605 read-circle numbers.
13606 (read_escape): Avoid int overflow.
13607 (Fload, openp, read_buffer_size, read1)
13608 (substitute_object_recurse, read_vector, read_list, map_obarray):
13609 Use ptrdiff_t, not int, for sizes.

13624 2011-06-22 Leo Liu <sdl.web@gmail.com>
13626 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
13627 Move to minibuffer.el.
13629 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
13631 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
13632 The following patches are for when GLYPH_DEBUG && !XASSERT.
13633 * dispextern.h (trace_redisplay_p, dump_glyph_string):
13634 * dispnew.c (flush_stdout):
13635 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
13636 Mark as externally visible.
13637 * dispnew.c (check_window_matrix_pointers): Now static.
13638 * dispnew.c (window_to_frame_vpos):
13639 * xfns.c (unwind_create_frame):
13640 * xterm.c (x_check_font): Remove unused local.
13641 * scroll.c (CHECK_BOUNDS):
13642 * xfaces.c (cache_fache): Rename local to avoid shadowing.
13643 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
13644 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
13645 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
13646 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
13648 (debug_method_add): Use va_list and vsprintf rather than relying
13649 on undefined behavior with wrong number of arguments.
13650 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
13651 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
13652 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
13653 since we're not interested in debugging glyphs with old libraries.
13654 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
13655 GCC 4.6.0's static checking.
13657 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
13659 Integer overflow and signedness fixes (Bug#8873).

13675 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
13676 (.bitmaps_last, struct x_output.icon_bitmap):
13677 Use ptrdiff_t, not int, for bitmap indexes.
13678 (x_allocate_bitmap_record): Check for size overflow.
13679 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
13681 Use ptrdiff_t, not int, for overlay counts.
13682 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
13683 * editfns.c (overlays_around, get_pos_property):
13684 * textprop.c (get_char_property_and_overlay):
13685 * xdisp.c (next_overlay_change, note_mouse_highlight):
13686 * xfaces.c (face_at_buffer_position):
13687 * buffer.c (OVERLAY_COUNT_MAX): New macro.
13688 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
13689 (Fnext_overlay_change, Fprevious_overlay_change)
13690 (mouse_face_overlay_overlaps, Foverlays_in):
13691 Use ptrdiff_t, not int, for sizes.
13692 (overlays_at, overlays_in): Check for size-calculation overflow.
13694 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
13696 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
13697 (x_session_initialize): Do not assume string length fits in int.
13699 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
13700 This is unlikely, but can occur if DPI is outlandish.
13702 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
13703 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
13705 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
13706 * xrdb.c (magic_file_p, search_magic_path):
13707 Omit last arg SUFFIX; it was always 0. All callers changed.
13708 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
13710 * xfont.c (xfont_match): Avoid need for strlen.
13712 * xfns.c: Don't assume strlen fits in int.

13715 * xdisp.c (message_log_check_duplicate): Return intmax_t,
13716 not unsigned long, as we prefer signed integers. All callers changed.
13717 Detect integer overflow in repeat count.
13718 (message_dolog): Don't assume print length fits in 39 bytes.
13719 (display_mode_element): Don't assume strlen fits in int.
13721 * termcap.c: Don't assume sizes fit in int and never overflow.
13722 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
13723 (gobble_line): Check for size-calculation overflow.
13725 * minibuf.c (Fread_buffer):
13726 * lread.c (intern, intern_c_string):
13727 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

13740 * filelock.c: Fix some buffer overrun and integer overflow issues.
13741 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
13742 Reformulate so as not to need the command string.
13743 Invoke gzip -cd rather than gunzip, as it's more portable.
13744 (lock_info_type, lock_file_1, lock_file):
13745 Don't assume pid_t and time_t fit in unsigned long.
13746 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
13747 (current_lock_owner): Prefer signed type for sizes.
13748 Use memcpy, not strncpy, where memcpy is what is really wanted.
13749 Don't assume (via atoi) that time_t and pid_t fit in int.
13750 Check for time_t and/or pid_t out of range, e.g., via a network share.
13751 Don't alloca where an auto var works fine.
13753 * fileio.c: Fix some integer overflow issues.
13754 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
13755 Don't assume string length fits in int.
13756 (directory_file_name): Don't assume string length fits in long.
13757 (make_temp_name): Don't assume pid fits in int, or that its print
13758 length is less than 20.
13760 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
13762 * coding.c (make_subsidiaries): Don't assume string length fits in int.

13777 (Fgetenv_internal):
13778 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
13780 * lread.c (invalid_syntax): Omit length argument.
13781 All uses changed. This doesn't fix a bug, but it simplifies the
13782 code away from its former Hollerith-constant appearance, and it's
13783 one less 'int' to worry about when looking at integer-overflow issues.
13784 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
13786 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
13787 This didn't break anything, but it didn't help either.
13788 It's confusing to put a bogus integer in a place where the actual
13789 value does not matter.
13790 (LIST_END_P): Remove unused macro and its bogus comment.
13791 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
13793 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
13794 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
13796 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
13797 We prefer signed types, and the value cannot exceed the EMACS_INT
13798 range anyway (because otherwise the length would not be representable).
13799 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
13800 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
13801 This avoids a GCC warning when WIDE_EMACS_INT.
13803 * indent.c (sane_tab_width): New function.
13804 (current_column, scan_for_column, Findent_to, position_indentation)
13805 (compute_motion): Use it. This is just for clarity.
13806 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
13808 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
13810 * lisp.h (lint_assume): New macro.
13811 * composite.c (composition_gstring_put_cache):
13812 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
13814 * editfns.c, insdel.c:
13815 Omit unnecessary forward decls, to simplify future changes.
13817 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
13819 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
13821 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
13822 Use much-faster test for byte-length change.
13823 Don't assume string byte-length fits in 'int'.
13824 Check that character arg fits in 'int'.
13825 (mapcar1): Declare byte as byte, for clarity.
13827 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
13829 * fns.c (concat): Catch string overflow earlier.
13830 Do not rely on integer wraparound.
13832 * dispextern.h (struct it.overlay_strings_charpos)
13833 (struct it.selective): Now EMACS_INT, not int.
13834 * xdisp.c (forward_to_next_line_start)
13835 (back_to_previous_visible_line_start)
13836 (reseat_at_next_visible_line_start, next_element_from_buffer):
13837 Don't arbitrarily truncate the value of 'selective' to int.
13839 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
13841 * composite.c: Don't truncate sizes to 'int'.
13842 (composition_gstring_p, composition_reseat_it)
13843 (composition_adjust_point): Use EMACS_INT, not int.
13844 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
13845 not EMACS_UINT, for indexes.
13847 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
13849 * buffer.c: Include <verify.h>.
13850 (struct sortvec.priority, struct sortstr.priority):
13851 Now EMACS_INT, not int.
13852 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
13853 (struct sortstr.size, record_overlay_string)
13854 (struct sortstrlist.size, struct sortlist.used):
13855 Don't truncate size to int.
13856 (record_overlay_string): Check for size-calculation overflow.
13857 (init_buffer_once): Check at compile-time, not run-time.
13859 2011-06-22 Jim Meyering <meyering@redhat.com>
13861 Don't leak an XBM-image-sized buffer
13862 * image.c (xbm_load): Free the image buffer after using it.
13864 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
13867 * composite.c (find_automatic_composition): Omit needless 'return 0;'
13868 that Sun C diagnosed.
13869 * fns.c (secure_hash): Fix pointer signedness issue.
13870 * intervals.c (static_offset_intervals): New function.
13871 (offset_intervals): Use it.
13873 2011-06-21 Leo Liu <sdl.web@gmail.com>
13876 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
13879 * fns.c (secure_hash): Rename from crypto_hash_function and change
13880 the first arg to accept symbols.
13881 (Fsecure_hash): New primitive.
13882 (syms_of_fns): New symbols.
13884 2011-06-20 Deniz Dogan <deniz@dogan.se>
13886 * process.c (Fset_process_buffer): Clarify return value in
13889 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
13891 * dispnew.c (add_window_display_history): Use BVAR.
13893 * xdisp.c (debug_method_add): Use BVAR.
13894 (check_window_end, dump_glyph_matrix, dump_glyph)
13895 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
13897 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
13900 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
13901 check till after the cache is created in init_frame_faces.
13903 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
13905 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
13907 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
13909 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
13910 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
13911 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
13913 Improve buffer-overflow checking (Bug#8873).
13914 * fileio.c (Finsert_file_contents):
13915 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
13916 Remove the old (too-loose) buffer overflow checks.
13917 They weren't needed, since make_gap checks for buffer overflow.
13918 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
13919 The old code merely checked for Emacs fixnum overflow, and relied
13920 on undefined (wraparound) behavior. The new code avoids undefined
13921 behavior, and also checks for ptrdiff_t and/or size_t overflow.
13923 * editfns.c (Finsert_char): Don't dump core with very negative counts.
13924 Tune. Don't use wider integers than needed. Don't use alloca.
13925 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
13927 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
13929 * insdel.c, lisp.h (buffer_overflow): New function.
13930 (insert_from_buffer_1, replace_range, replace_range_2):
13931 * insdel.c (make_gap_larger):
13932 * editfns.c (Finsert_char):
13933 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
13935 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
13937 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
13939 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
13941 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
13942 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
13944 * fileio.c: Don't assume EMACS_INT fits in off_t.
13945 (emacs_lseek): New static function.
13946 (Finsert_file_contents, Fwrite_region): Use it.
13947 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
13949 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
13951 * fns.c: Don't overflow int when computing a list length.
13952 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
13953 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
13954 truncation on 64-bit hosts. Check for QUIT every
13955 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
13956 faster and is responsive enough.
13957 (Flength): Report an error instead of overflowing an integer.
13958 (Fsafe_length): Return a float if the value is not representable
13959 as a fixnum. This shouldn't happen except in contrived situations.
13960 (Fnthcdr, Fsort): Don't assume list length fits in int.
13961 (Fcopy_sequence): Don't assume vector length fits in int.
13963 * alloc.c: Check that resized vectors' lengths fit in fixnums.
13964 (header_size, word_size): New constants.
13965 (allocate_vectorlike): Don't check size overflow here.
13966 (allocate_vector): Check it here instead, since this is the only
13967 caller of allocate_vectorlike that could cause overflow.
13968 Check that the new vector's length is representable as a fixnum.
13970 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
13971 The previous code was bogus. For example, next_almost_prime (32)
13972 returned 39, which is undesirable as it is a multiple of 3; and
13973 next_almost_prime (24) returned 25, which is a multiple of 5 so
13974 why was the code bothering to check for multiples of 7?
13976 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
13978 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
13980 Variadic C functions now count arguments with ptrdiff_t.
13981 This partly undoes my 2011-03-30 change, which replaced int with size_t.
13982 Back then I didn't know that the Emacs coding style prefers signed int.
13983 Also, in the meantime I found a few more instances where arguments
13984 were being counted with int, which may truncate counts on 64-bit
13985 machines, or EMACS_INT, which may be unnecessarily wide.
13986 * lisp.h (struct Lisp_Subr.function.aMANY)
13987 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
13988 Arg counts are now ptrdiff_t, not size_t.
13989 All variadic functions and their callers changed accordingly.
13990 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
13991 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
13992 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
13993 * callint.c (Fcall_interactively): Check arg count for overflow,
13994 to avoid potential buffer overrun. Use signed char, not 'int',
13995 for 'varies' array, so that we needn't bother to check its size
13996 calculation for overflow.
13997 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
13998 * eval.c (apply_lambda):
13999 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
14000 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
14001 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
14003 * callint.c (Fcall_interactively): Don't use index var as event count.
14005 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
14006 * mem-limits.h (SIZE): Remove; no longer used.
14008 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
14010 Remove unnecessary casts.
14011 * xterm.c (x_term_init):
14012 * xfns.c (x_set_border_pixel):
14013 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
14014 These aren't needed now that we assume ANSI C.
14016 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
14017 It's more likely to cause problems (due to unsigned overflow)
14020 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
14022 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
14024 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
14026 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
14028 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
14030 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
14032 GLYPH_CODE_FACE returns EMACS_INT, not int.
14033 * dispextern.h (merge_faces):
14034 * xfaces.c (merge_faces):
14035 * xdisp.c (get_next_display_element, next_element_from_display_vector):
14036 Don't assume EMACS_INT fits in int.
14038 * character.h (CHAR_VALID_P): Remove unused parameter.
14039 * fontset.c, lisp.h, xdisp.c: All uses changed.
14041 * editfns.c (Ftranslate_region_internal): Omit redundant test.
14043 * fns.c (concat): Minor tuning based on overflow analysis.
14044 This doesn't fix any bugs. Use int to hold character, instead
14045 of constantly refetching from Emacs object. Use XFASTINT, not
14046 XINT, for value known to be a character. Don't bother comparing
14047 a single byte to 0400, as it's always less.
14049 * floatfns.c (Fexpt):
14050 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
14052 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
14055 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
14057 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
14058 Without this fix, on a 64-bit host (aset S 0 4294967386) would
14059 incorrectly succeed when S was a string, because 4294967386 was
14060 truncated before it was used.
14062 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
14063 Otherwise, an out-of-range integer could cause undefined behavior
14066 * composite.c: Use int, not EMACS_INT, for characters.
14067 (fill_gstring_body, composition_compute_stop_pos): Use int, not
14068 EMACS_INT, for values that are known to be in character range.
14069 This doesn't fix any bugs but is the usual style inside Emacs and
14070 may generate better code on 32-bit machines.
14072 Make sure a 64-bit char is never passed to ENCODE_CHAR.
14073 This is for reasons similar to the recent CHAR_STRING fix.
14074 * charset.c (Fencode_char): Check that character arg is actually
14075 a character. Pass an int to ENCODE_CHAR.
14076 * charset.h (ENCODE_CHAR): Verify that the character argument is no
14077 wider than 'int', as a compile-time check to prevent future regressions
14080 * character.c (char_string): Remove unnecessary casts.
14082 Make sure a 64-bit char is never passed to CHAR_STRING.
14083 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
14084 by silently ignoring the top 32 bits, allowing some values
14085 that were far too large to be valid characters.
14086 * character.h: Include <verify.h>.
14087 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
14088 arguments are no wider than unsigned, as a compile-time check
14089 to prevent future regressions in this area.
14091 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
14092 (Fsubst_char_in_region):
14094 * xdisp.c (decode_mode_spec_coding):
14095 Adjust to CHAR_STRING's new requirement.
14096 * editfns.c (Finsert_char, Fsubst_char_in_region):
14097 * fns.c (concat): Check that character args are actually
14098 characters. Without this test, these functions did the wrong
14099 thing with wildly out-of-range values on 64-bit hosts.
14101 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
14102 These casts should not be needed on 32-bit hosts, either.
14103 * keyboard.c (read_char):
14104 * lread.c (Fload): Remove casts to unsigned.
14106 * lisp.h (UNSIGNED_CMP): New macro.
14107 This fixes comparison bugs on 64-bit hosts.
14108 (ASCII_CHAR_P): Use it.
14109 * casefiddle.c (casify_object):
14110 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
14111 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
14112 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
14113 * dispextern.h (FACE_FROM_ID):
14114 * keyboard.c (read_char): Use UNSIGNED_CMP.
14116 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
14117 not to EMACS_INT, to avoid GCC warning.
14119 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
14121 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
14122 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
14123 isn't needed on 32-bit machines.
14125 * buffer.c (Fgenerate_new_buffer_name):
14126 Use EMACS_INT for count, not int.
14127 (advance_to_char_boundary): Return EMACS_INT, not int.
14129 * data.c (Qcompiled_function): Now static.
14131 * window.c (window_body_lines): Now static.
14133 * image.c (gif_load): Rename local to avoid shadowing.
14135 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
14136 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
14137 * alloc.c (make_save_value): Integer argument is now of type
14138 ptrdiff_t, not int.
14139 (mark_object): Use ptrdiff_t, not int.
14140 * lisp.h (pD): New macro.
14141 * print.c (print_object): Use it.
14143 * alloc.c: Use EMACS_INT, not int, to count objects.
14144 (total_conses, total_markers, total_symbols, total_vector_size)
14145 (total_free_conses, total_free_markers, total_free_symbols)
14146 (total_free_floats, total_floats, total_free_intervals)
14147 (total_intervals, total_strings, total_free_strings):
14148 Now EMACS_INT, not int. All uses changed.
14149 (Fgarbage_collect): Compute overall total using a double, so that
14150 integer overflow is less likely to be a problem. Check for overflow
14151 when converting back to an integer.
14152 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
14153 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
14154 These were 'int' variables that could overflow on 64-bit hosts;
14155 they were never used, so remove them instead of repairing them.
14156 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
14157 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
14158 Previously, this ceilinged at INT_MAX, but that doesn't work on
14160 (allocate_pseudovector): Don't use EMACS_INT when int would do.
14162 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
14163 (allocate_vectorlike): Check for ptrdiff_t overflow.
14164 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
14165 when a (possibly-narrower) signed value would do just as well.
14166 We prefer using signed arithmetic, to avoid comparison confusion.
14168 * alloc.c: Catch some string size overflows that we were missing.
14169 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
14170 for convenience in STRING_BYTES_MAX.
14171 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
14172 The definition here is exact; the one in lisp.h was approximate.
14173 (allocate_string_data): Check for string overflow. This catches
14174 some instances we weren't catching before. Also, it catches
14175 size_t overflow on (unusual) hosts where SIZE_MAX <= min
14176 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
14177 and ptrdiff_t and EMACS_INT are both 64 bits.
14179 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
14180 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
14181 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
14183 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
14185 * alloc.c (Fmake_string): Check for out-of-range init.
14187 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
14189 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
14191 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
14193 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
14194 xg_get_default_scrollbar_width.
14196 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
14197 (int_gtk_range_get_value): Move to the scroll bar part of the file.
14198 (style_changed_cb): Call update_theme_scrollbar_width and call
14199 x_set_scroll_bar_default_width and xg_frame_set_char_size for
14200 all frames (Bug#8505).
14201 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
14202 Call gtk_window_set_resizable if HAVE_GTK3.
14203 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
14204 and height if HAVE_GTK3 (Bug#8505).
14205 (scroll_bar_width_for_theme): New variable.
14206 (update_theme_scrollbar_width): New function.
14207 (xg_get_default_scrollbar_width): Move code to
14208 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
14209 (xg_initialize): Call update_theme_scrollbar_width.
14211 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
14213 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
14215 2011-06-12 Martin Rudalics <rudalics@gmx.at>
14217 * frame.c (make_frame): Call other_buffer_safely instead of
14220 * window.c (temp_output_buffer_show): Call display_buffer with
14221 second argument Vtemp_buffer_show_specifiers and reset latter
14222 immediately after the call.
14223 (Vtemp_buffer_show_specifiers): New variable.
14224 (auto_window_vscroll_p, next_screen_context_lines)
14225 (Vscroll_preserve_screen_position): Remove leading asterisks from
14228 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
14230 Fix minor problems found by GCC 4.6.0 static checking.
14231 * buffer.c (Qclone_number): Remove for now, as it's unused.
14232 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
14233 (record_buffer): Remove unused local.
14234 * frame.c (other_visible_frames, frame_buffer_list): Now static.
14235 (set_frame_buffer_list): Remove; unused.
14236 * frame.h (other_visible_frames): Remove decl.
14237 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
14238 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
14239 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
14241 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
14242 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
14243 Define only if HAVE_GPM.
14244 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
14245 (update_hints_inhibit): Remove; never set. All uses removed.
14246 * widgetprv.h (emacsFrameClassRec): Remove decl.
14247 * window.c (delete_deletable_window): Now returns void, since it
14248 wasn't returning anything.
14249 (compare_window_configurations): Remove unused locals.
14250 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
14251 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
14252 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
14253 the same widths as pointers. This follows up on the 2011-05-06 patch.
14254 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
14255 * xterm.h: Likewise.
14256 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
14258 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
14260 * makefile.w32-in: Update dependencies.
14261 (LISP_H): Add lib/intprops.h.
14263 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
14265 * image.c (gif_load): Add animation frame delay to the metadata.
14266 (syms_of_image): Use DEFSYM. New symbol `delay'.
14268 2011-06-11 Martin Rudalics <rudalics@gmx.at>
14270 * window.c (delete_deletable_window): Re-add.
14271 (Fset_window_configuration): Rewrite to handle dead buffers and
14272 consequently deletable windows.
14273 (window_tree, Fwindow_tree): Remove. Supply functionality in
14275 (compare_window_configurations): Simplify code.
14277 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
14279 * image.c (imagemagick_load_image): Fix type mismatch.
14280 (Fimagemagick_types): Likewise.
14282 * window.h (replace_buffer_in_windows): Declare.
14284 2011-06-11 Martin Rudalics <rudalics@gmx.at>
14286 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
14287 Qclone_number. Remove external declaration of Qdelete_window.
14288 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
14290 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
14291 Run Qbuffer_list_update_hook if allowed.
14292 (Fother_buffer): Rewrite doc-string. Major rewrite for new

14745 (bidi_cache_search, bidi_cache_iterator_state)
14746 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
14747 (bidi_level_of_next_char, bidi_move_to_visually_next):
14748 Support character positions inside a run of characters covered by a
14750 (bidi_paragraph_init, bidi_resolve_explicit_1)
14751 (bidi_level_of_next_char): Call bidi_fetch_char and
14752 bidi_fetch_char_advance instead of FETCH_CHAR and
14753 FETCH_CHAR_ADVANCE.
14754 (bidi_init_it): Initialize new members.
14755 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
14757 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
14758 instead of using explicit *_CHAR codes.
14759 (bidi_resolve_explicit, bidi_resolve_weak):
14760 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
14761 bidirectional text is supported only in multibyte buffers.
14762 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
14763 it to initialize the frame_window_p member of struct bidi_it.
14764 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
14765 (bidi_resolve_explicit, bidi_resolve_weak)
14766 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
14767 bidi_it->nchars is non-positive.
14768 (bidi_level_of_next_char): Don't try to lookup the cache for the
14769 next/previous character if nothing is cached there yet, or if we
14770 were just reseat()'ed to a new position.
14772 * xdisp.c (set_cursor_from_row): Set start and stop points
14773 according to the row's direction when priming the loop that looks
14774 for the glyph on which to display cursor.
14775 (single_display_spec_intangible_p): Function deleted.
14776 (display_prop_intangible_p): Reimplement to call
14777 handle_display_spec instead of single_display_spec_intangible_p.
14778 Accept 3 additional arguments needed by handle_display_spec.
14779 This fixes incorrect cursor motion across display property with complex
14780 values: lists, `(when COND...)' forms, etc.
14781 (single_display_spec_string_p): Support property values that are
14782 lists with the argument STRING its top-level element.
14783 (display_prop_string_p): Fix the condition for processing a
14784 property that is a list to be consistent with handle_display_spec.
14785 (handle_display_spec): New function, refactored from the
14786 last portion of handle_display_prop.
14787 (compute_display_string_pos): Accept additional argument
14788 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
14789 value of a `display' property is a "replacing spec".
14790 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
14791 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
14792 the display property, but just return a value indicating whether
14793 the display property will replace the characters it covers.
14794 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
14795 frame_window_p members of struct bidi_it.
14796 (compute_display_string_pos, compute_display_string_end):
14798 (push_it): Accept second argument POSITION, where pop_it should
14799 jump to continue iteration.
14800 (reseat_1): Initialize bidi_it.disp_pos.
14802 * keyboard.c (adjust_point_for_property): Adjust the call to
14803 display_prop_intangible_p to its new signature.
14805 * dispextern.h (struct bidi_it): New member frame_window_p.
14806 (bidi_init_it): Update prototypes.
14807 (display_prop_intangible_p): Update prototype.
14808 (compute_display_string_pos, compute_display_string_end):
14809 Declare prototypes.

14816 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
14817 * lisp.h: Change signatures accordingly.
14818 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
14819 All callers changed. (Bug#8762)
14821 * gnutls.c: Use Emacs's memory allocators.
14822 Without this change, the gnutls library would invoke malloc etc.
14823 directly, which causes problems on non-SYNC_INPUT hosts, and which
14824 runs afoul of improving memory_full behavior. (Bug#8761)
14825 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
14826 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
14827 xfree instead of the default malloc, realloc, free.
14828 (Fgnutls_boot): No need to check for memory allocation failure,
14829 since xmalloc does that for us.
14831 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
14832 * category.c (hash_get_category_set):
14833 * ccl.c (ccl_driver):

14845 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
14846 (Fsxhash, Fgethash, Fputhash, Fmaphash):
14847 * image.c (make_image, search_image_cache, lookup_image)
14848 (xpm_put_color_table_h):
14849 * lisp.h (struct Lisp_Hash_Table):
14850 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
14851 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
14852 for hashes and hash indexes, instead of 'unsigned' and 'int'.
14853 * alloc.c (allocate_vectorlike):
14854 Check for overflow in vector size calculations.
14855 * ccl.c (ccl_driver):
14856 Check for overflow when converting EMACS_INT to int.
14857 * fns.c, image.c: Remove unnecessary static decls that would otherwise
14858 need to be updated by these changes.
14859 * fns.c (make_hash_table, maybe_resize_hash_table):
14860 Check for integer overflow with large hash tables.
14861 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
14862 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
14863 (SXHASH_REDUCE): New macro.
14864 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
14865 Use it instead of discarding useful hash info with large hash values.
14866 (sxhash_float): New function.
14867 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
14868 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
14869 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
14870 Rewrite to use FIXNUM_BITS, as this simplifies things.
14871 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
14872 Adjust signatures to match updated version of code.
14873 (consing_since_gc): Now EMACS_INT, since a single hash table can
14874 use more than INT_MAX bytes.
14876 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
14878 Make it possible to build with GCC-4.6+ -O2 -flto.
14880 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
14882 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
14884 * minibuf.c (get_minibuffer, read_minibuf_unwind):
14885 Call minibuffer-inactive-mode.
14887 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
14889 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
14890 Update dependencies.
14892 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14894 * data.c (init_data): Remove code for UTS, this system is not
14897 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14899 Don't force ./temacs to start in terminal mode.
14901 * frame.c (make_initial_frame): Initialize faces in all cases, not
14902 only when CANNOT_DUMP is defined.
14903 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
14905 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14907 * dispnew.c (add_window_display_history): Use const for the string
14908 pointer. Remove declaration, not needed.
14910 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
14912 Use 'inline', not 'INLINE'.
14913 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
14914 * alloc.c, fontset.c (INLINE): Remove.
14915 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
14916 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
14917 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
14918 * gmalloc.c (register_heapinfo): Use inline unconditionally.
14919 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
14921 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14923 Make it possible to run ./temacs.
14925 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
14926 syms_of_callproc does the same thing. Remove test for
14927 "initialized", do it in the caller.
14928 * emacs.c (main): Avoid calling set_initial_environment when dumping.
14930 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
14932 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
14933 (read_minibuf): Use get_minibuffer.
14934 (syms_of_minibuf): Use DEFSYM.
14935 (Qmetadata): New var.
14936 * data.c (Qbuffer): Don't make it static.
14937 (syms_of_data): Use DEFSYM.
14939 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
14941 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
14942 (CCL_CODE_MIN): New macro.
14944 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
14946 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
14948 * eval.c (Qdebug): Now static.
14949 * lisp.h (Qdebug): Remove decl. This reverts a part of the
14950 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
14951 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
14953 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14955 * image.c: Various fixes to ImageMagick code comments.
14956 (Fimagemagick_types): Doc fix.
14958 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
14960 Minor fixes prompted by GCC 4.6.0 warnings.
14962 * xselect.c (converted_selections, conversion_fail_tag): Now static.
14964 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
14965 (x_clipboard_manager_save_all): Move extern decl to ...
14966 * xterm.h: ... here, so that it can be checked for consistency.
14968 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14970 * xselect.c (x_clipboard_manager_save_frame)
14971 (x_clipboard_manager_save_all): New functions.
14972 (Fx_clipboard_manager_save): Lisp function deleted.
14974 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
14975 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
14977 * xterm.h: Update prototype.
14979 2011-05-28 William Xu <william.xwl@gmail.com>
14981 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
14982 exiting (Bug#8239).
14984 2011-05-28 Jim Meyering <meyering@redhat.com>
14986 Avoid a sign-extension bug in crypto_hash_function.
14987 * fns.c (to_uchar): Define.
14988 (crypto_hash_function): Use it to convert some newly-signed
14989 variables to unsigned, to avoid sign-extension bugs. For example,
14990 without this change, (md5 "truc") would evaluate to
14991 45723a2aff78ff4fff7fff1114760e62 rather than the expected
14992 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
14993 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
14995 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14997 Integer overflow fixes.
14999 * dbusbind.c: Serial number integer overflow fixes.
15000 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
15001 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
15002 to hold a serial number that is too large for a fixnum.
15003 (Fdbus_method_return_internal, Fdbus_method_error_internal):
15004 Check for serial numbers out of range. Decode any serial number
15005 that was so large that it became a float. (Bug#8722)
15007 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
15008 (Fdbus_call_method, Fdbus_call_method_asynchronously):
15009 Use XFASTINT rather than XUINT when numbers are nonnegative.
15010 (xd_append_arg, Fdbus_method_return_internal):
15011 (Fdbus_method_error_internal): Likewise. Also, for unsigned
15012 arguments, check that Lisp number is nonnegative, rather than
15013 silently wrapping negative numbers around. (Bug#8722)
15014 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
15017 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
15019 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
15021 ccl: Add integer overflow checks.
15022 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
15023 (IN_INT_RANGE): New macros.
15024 (ccl_driver): Use them to check for integer overflow when
15025 decoding a CCL program. Many of the new checks are whether XINT (x)
15026 fits in int; it doesn't always, on 64-bit hosts. The new version
15027 doesn't catch all possible integer overflows, but it's an
15028 improvement. (Bug#8719)
15030 * alloc.c (make_event_array): Use XINT, not XUINT.
15031 There's no need for unsigned here.
15033 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
15034 This follows up to the 2011-05-06 change that substituted uintptr_t
15035 for EMACS_INT. This case wasn't caught back then.
15037 Rework Fformat to avoid integer overflow issues.
15038 * editfns.c: Include <float.h> unconditionally, as it's everywhere
15039 now (part of C89). Include <verify.h>.
15040 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
15041 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
15042 (Fformat): Avoid the prepass trying to compute sizes; it was only
15043 approximate and thus did not catch overflow reliably. Instead, walk
15044 through the format just once, formatting and computing sizes as we go,
15045 checking for integer overflow at every step, and allocating a larger
15046 buffer as needed. Keep track separately whether the format is
15047 multibyte. Keep only the most-recently calculated precision, rather
15048 than them all. Record whether each argument has been converted to
15049 string. Use EMACS_INT, not int, for byte and char and arg counts.
15050 Support field widths and precisions larger than INT_MAX. Avoid
15051 sprintf's undefined behavior with conversion specifications such as %#d
15052 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
15053 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
15054 formatting out-of-range floating point numbers with int
15055 formats. (Bug#8668)
15057 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
15059 * data.c: Avoid integer truncation in expressions involving floats.
15060 * data.c: Include <intprops.h>.
15061 (arith_driver): When there's an integer overflow in an expression
15062 involving floating point, convert the integers to floating point
15063 so that the resulting value does not suffer from catastrophic
15064 integer truncation. For example, on a 64-bit host (* 4
15065 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
15066 Do not rely on undefined behavior after integer overflow.
15068 merge count_size_as_multibyte, parse_str_to_multibyte
15069 * character.c, character.h (count_size_as_multibyte):
15070 Rename from parse_str_to_multibyte; all uses changed.
15071 Check for integer overflow.
15072 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
15073 since it's now a duplicate of the other. This is more of
15074 a character than a buffer op, so better that it's in character.c.
15075 * fns.c, print.c: Adjust to above changes.
15077 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
15079 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
15081 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
15083 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
15084 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
15085 (x_clipboard_manager_save): Now static.
15086 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
15088 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
15089 (crypto_hash_function): Now static.
15090 Fix pointer signedness problems. Avoid unnecessary initializations.
15092 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
15094 * termhooks.h (Vselection_alist): Make it terminal-local.
15096 * terminal.c (create_terminal): Initialize it.
15098 * xselect.c: Support for clipboard managers.
15099 (Vselection_alist): Move to termhooks.h as terminal-local var.
15100 (LOCAL_SELECTION): New macro.
15101 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
15102 (symbol_to_x_atom): Remove gratuitous arg.
15103 (x_handle_selection_request, lisp_data_to_selection_data)
15104 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
15105 (x_own_selection, x_get_local_selection, x_convert_selection):
15106 New arg, specifying work frame. Use terminal-local Vselection_alist.
15107 (some_frame_on_display): Delete unused function.
15108 (Fx_own_selection_internal, Fx_get_selection_internal)
15109 (Fx_disown_selection_internal, Fx_selection_owner_p)
15110 (Fx_selection_exists_p): New optional frame arg.
15111 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
15112 (x_handle_selection_clear): Don't treat other terminals with the
15113 same keyboard specially. Use the terminal-local Vselection_alist.
15114 (x_clear_frame_selections): Use Frun_hook_with_args.
15116 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
15118 * xterm.h: Add support for those atoms.
15120 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
15122 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
15123 (converted_selections, conversion_fail_tag): New global variables.
15124 (x_selection_request_lisp_error): Free the above.
15125 (x_get_local_selection): Remove unnecessary code.
15126 (x_reply_selection_request): Args changed; handle arbitrary array
15127 of converted selections stored in converted_selections.
15128 Separate the XChangeProperty and SelectionNotify steps.
15129 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
15130 (x_convert_selection): New function.
15131 (x_handle_selection_event): Simplify.
15132 (x_get_foreign_selection): Don't ignore incoming requests while
15133 waiting for an answer; this will fail when we implement
15134 SAVE_TARGETS, and seems unnecessary anyway.
15135 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
15136 (Vx_sent_selection_functions): Doc fix.
15138 2011-05-26 Leo Liu <sdl.web@gmail.com>
15140 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
15142 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15144 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
15146 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
15147 for fringe update if it has periodic bitmap.
15148 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
15149 and fringe_bitmap_periodic_p.
15151 * fringe.c (get_fringe_bitmap_data): New function.
15152 (draw_fringe_bitmap_1, update_window_fringes): Use it.
15153 (update_window_fringes): Record periodicity of fringe bitmap in glyph
15154 row. Mark glyph row for fringe update if periodicity changed.
15156 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
15157 for fringe update unless it has periodic bitmap.
15159 2011-05-25 Kenichi Handa <handa@m17n.org>
15161 * xdisp.c (get_next_display_element): Set correct it->face_id for
15162 a static composition.
15164 2011-05-24 Leo Liu <sdl.web@gmail.com>
15167 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
15169 * fns.c (crypto_hash_function, Fsha1): New function.
15170 (Fmd5): Use crypto_hash_function.
15171 (syms_of_fns): Add Ssha1.
15173 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
15175 * gnutls.c: Remove unused macros.
15176 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
15177 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
15178 Remove macros that are defined and never used.
15179 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
15181 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
15183 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
15184 (Fx_get_selection_internal): Minor cleanup.
15185 (Fx_own_selection_internal): Rename arguments for consistency with
15188 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
15190 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
15192 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
15194 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
15196 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15198 * dispnew.c (scrolling_window): Don't exclude the case that the
15199 last enabled row in the desired matrix touches the bottom boundary.
15201 2011-05-21 Glenn Morris <rgm@gnu.org>
15203 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
15204 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
15205 and add some more files.
15207 2011-05-20 Eli Zaretskii <eliz@gnu.org>
15209 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
15210 report_file_error introduced by the change from 2011-05-07.
15212 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
15214 * systime.h (Time): Define only if emacs is defined.
15215 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
15216 where the include path doesn't have X11/X.h by default. See
15217 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
15219 2011-05-20 Kenichi Handa <handa@m17n.org>
15221 * composite.c (find_automatic_composition): Fix previous change.
15223 2011-05-20 Glenn Morris <rgm@gnu.org>
15225 * lisp.mk: New file, split from Makefile.in.
15226 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
15227 (shortlisp): Remove.
15228 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
15230 2011-05-19 Glenn Morris <rgm@gnu.org>
15232 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
15233 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
15234 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
15235 (lisp): Set the order to that of loadup.el.
15236 (shortlisp): Make it a copy of $lisp.
15237 (SOME_MACHINE_LISP): Remove.
15238 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
15239 Use just $shortlisp, not $SOME_MACHINE_LISP too.
15241 2011-05-18 Kenichi Handa <handa@m17n.org>
15243 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
15244 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
15245 (find_automatic_composition): Mostly rewrite for efficiency.
15247 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
15249 * makefile.w32-in: Update dependencies.
15251 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
15253 * menu.c: Include limits.h (fixes the MS-Windows build broken by
15254 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
15256 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
15258 Fix some integer overflow issues, such as string length overflow.
15260 * insdel.c (count_size_as_multibyte): Check for string overflow.
15262 * character.c (lisp_string_width): Check for string overflow.
15263 Use EMACS_INT, not int, for string indexes and lengths; in
15264 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
15265 the resulting string length overflows an EMACS_INT; instead,
15266 report a string overflow if no precision given. When checking for
15267 precision exhaustion, use a check that cannot possibly have
15268 integer overflow. (Bug#8675)
15269 * character.h (lisp_string_width): Adjust to new signature.
15271 * alloc.c (string_overflow): New function.
15272 (Fmake_string): Use it. This doesn't change behavior, but saves
15273 a few bytes and will simplify future changes.
15274 * character.c (string_escape_byte8): Likewise.
15275 * lisp.h (string_overflow): New decl.
15277 Fixups, following up to the user-interface timestamp change.
15278 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
15279 for UI timestamps, instead of unsigned long.
15280 * msdos.c (mouse_get_pos): Likewise.
15281 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
15282 * w32gui.h (Time): Define by including "systime.h" rather than by
15283 declaring it ourselves. (Bug#8664)
15285 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
15286 * image.c (clear_image_cache): Likewise.
15288 * term.c (term_mouse_position): Don't assume time_t wraparound.
15290 Be more systematic about user-interface timestamps.
15291 Before, the code sometimes used 'Time', sometimes 'unsigned long',
15292 and sometimes 'EMACS_UINT', to represent these timestamps.
15293 This change causes it to use 'Time' uniformly, as that's what X uses.
15294 This makes the code easier to follow, and makes it easier to catch
15295 integer overflow bugs such as Bug#8664.
15296 * frame.c (Fmouse_position, Fmouse_pixel_position):
15297 Use Time, not unsigned long, for user-interface timestamps.
15298 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
15299 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
15300 * keyboard.h (last_event_timestamp): Likewise.
15301 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
15302 * menu.h (xmenu_show): Likewise.
15303 * term.c (term_mouse_position): Likewise.
15304 * termhooks.h (struct input_event.timestamp): Likewise.
15305 (struct terminal.mouse_position_hook): Likewise.
15306 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
15307 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
15308 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
15309 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
15310 what it was before.
15311 * menu.h, termhooks.h: Include "systime.h", for Time.
15313 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
15314 Don't assume that the difference between two unsigned long values
15315 can fit into an integer. At this point, we know button_down_time
15316 <= event->timestamp, so the difference must be nonnegative, so
15317 there's no need to cast the result if double-click-time is
15318 nonnegative, as it should be; check that it's nonnegative, just in
15319 case. This bug is triggered when events are more than 2**31 ms
15320 apart (about 25 days). (Bug#8664)
15322 * xselect.c (last_event_timestamp): Remove duplicate decl.
15323 (x_own_selection): Remove needless cast to unsigned long.
15325 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
15326 that always fit in int. Use a sentinel instead of a counter, to
15327 avoid a temp and to allay GCC's concerns about possible int overflow.
15328 * frame.h (struct frame): Use int for menu_bar_items_used
15329 instead of EMACS_INT, since it always fits in int.
15331 * menu.c (grow_menu_items): Check for int overflow.
15333 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
15335 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
15336 Before, the code was not consistent. These values cannot exceed
15337 2**31 - 1 so there's no need to make them unsigned.
15338 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
15339 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
15340 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
15342 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
15344 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
15345 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
15346 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
15347 presumably because the widths might not match.
15349 * window.c (size_window): Avoid needless test at loop start.
15351 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
15353 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
15355 2011-05-12 Drew Adams <drew.adams@oracle.com>
15357 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
15359 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15361 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
15362 `width' to `bar_area_x' and `bar_area_width', respectively.
15363 (x_scroll_run): Take account of fringe background extension.
15365 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
15366 Rename local vars `left' and `width' to `bar_area_x' and
15367 `bar_area_width', respectively.
15368 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
15369 background extension.
15371 2011-05-10 Jim Meyering <meyering@redhat.com>
15373 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
15375 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
15377 * image.c (Finit_image_library): Return t for built-in image types,
15378 like pbm and xbm. (Bug#8640)
15380 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
15382 * w32menu.c (set_frame_menubar): Fix submenu allocation.
15384 2011-05-07 Eli Zaretskii <eliz@gnu.org>
15386 * w32console.c (Fset_screen_color): Doc fix.
15387 (Fget_screen_color): New function.
15388 (syms_of_ntterm): Defsubr it.
15390 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
15391 unlink the temporary file if Fcall_process didn't create it in the
15393 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
15394 child process will be redirected to a file specified with `:file'.
15395 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
15396 cue to call_process_cleanup not to close that handle.
15398 2011-05-07 Ben Key <bkey76@gmail.com>
15400 * makefile.w32-in: The bootstrap-temacs rule now makes use of
15401 one of two shell specific rules, either bootstrap-temacs-CMD or
15402 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
15403 to the previous implementation of the bootstrap-temacs rule.
15404 The bootstrap-temacs-CMD rule is similar to the previous
15405 implementation of the bootstrap-temacs rule except that it
15406 makes use of the ESC_CFLAGS variable instead of the CFLAGS
15409 These changes, along with some changes to nt/configure.bat,
15410 nt/gmake.defs, and nt/nmake.defs, are required to extend my
15411 earlier fix to add support for --cflags and --ldflags options
15412 that include quotes so that it works whether make uses cmd or
15415 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
15417 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
15418 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
15420 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
15421 a string. Handle both cases.
15422 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
15423 (Fdbus_register_method): Use Qinvalid_function.
15425 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
15427 * makefile.w32-in: Update dependencies.
15428 (LISP_H): Add inttypes.h and stdin.h.
15429 (PROCESS_H): Add unistd.h.
15431 2011-05-06 Eli Zaretskii <eliz@gnu.org>
15433 * lread.c: Include limits.h (fixes the MS-Windows build broken by
15434 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
15436 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
15438 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
15440 * term.c (vfatal): Remove stray call to va_end.
15441 It's not needed and the C Standard doesn't allow it here anyway.
15443 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
15444 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
15446 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
15449 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
15451 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15453 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
15455 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
15457 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
15459 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
15460 * charset.c (Fdefine_charset_internal): Don't initialize
15461 charset.code_space[15]. The value was garbage, on hosts with
15462 32-bit int (Bug#8600).
15464 * lread.c (read_integer): Be more consistent with string-to-number.
15465 Use string_to_number to do the actual conversion; this avoids
15466 rounding errors and fixes some other screwups. Without this fix,
15467 for example, #x1fffffffffffffff was misread as -2305843009213693952.
15468 (digit_to_number): Move earlier, for benefit of read_integer.
15469 Return -1 if the digit is out of range for the base, -2 if it is
15470 not a digit in any supported base. (Bug#8602)
15472 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
15474 * dispnew.c (scrolling_window): Return 1 if we scrolled,
15475 to match comment at start of function. This also removes a
15476 GCC warning about overflow in a 32+64-bit port.
15478 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
15480 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
15481 Reported by Stefan Monnier in
15482 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
15483 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
15484 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
15486 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
15487 (EMACS_UINTPTR): Likewise, with uintptr_t.
15489 * lisp.h: Prefer 64-bit EMACS_INT if available.
15490 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
15491 on 32-bit hosts that have 64-bit int, so that they can access
15493 However, temporarily disable this change unless the temporary
15494 symbol WIDE_EMACS_INT is defined.
15496 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
15498 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
15499 This removes an assumption that EMACS_INT and long are the same
15500 width as pointers. The assumption is true for Emacs porting targets
15501 now, but we want to make other targets possible.
15502 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
15503 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
15504 In the rest of the code, change types of integers that hold casted
15505 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
15506 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
15507 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
15508 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
15509 No need to cast type when ORing.
15510 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
15511 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
15512 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
15513 assume EMACS_INT is the same width as char *.
15514 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
15515 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
15516 Remove no-longer-needed casts.
15517 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
15518 (xg_tool_bar_help_callback, xg_make_tool_item):
15519 Use EMACS_INTPTR to hold an integer
15520 that will be cast to void *; this can avoid a GCC warning
15521 if EMACS_INT is not the same width as void *.
15522 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
15523 * xdisp.c (display_echo_area_1, resize_mini_window_1):
15524 (current_message_1, set_message_1):
15525 Use a local to convert to proper width without a cast.
15526 * xmenu.c (dialog_selection_callback): Likewise.
15528 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
15529 Also, don't assume VALBITS / RAND_BITS is less than 5,
15530 and don't rely on undefined behavior when shifting a 1 left into
15532 * lisp.h (get_random): Change signature to match.
15534 * lread.c (hash_string): Use size_t, not int, for hash computation.
15535 Normally we prefer signed values; but hashing is special, because
15536 it's better to use unsigned division on hash table sizes so that
15537 the remainder is nonnegative. Also, size_t is the natural width
15538 for hashing into memory. The previous code used 'int', which doesn't
15539 retain enough info to hash well into very large tables.
15540 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
15542 * dbusbind.c: Don't possibly lose pointer info when converting.
15543 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
15544 Use XPNTR rather than XHASH, so that the high-order bits of
15545 the pointer aren't lost when converting through void *.
15547 * eval.c (Fautoload): Don't double-shift a pointer.
15549 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
15551 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
15553 * gnutls.c (DEF_GNUTLS_FN):
15554 * image.c (DEF_IMGLIB_FN): Make function pointers static.
15556 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
15558 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
15561 2011-05-05 Eli Zaretskii <eliz@gnu.org>
15563 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
15564 New version that can reserve upto 2GB of heap space.
15566 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
15568 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
15570 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
15572 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
15573 `gnutls_certificate_set_x509_key_file'.
15575 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
15577 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
15578 Update dependencies.
15580 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15582 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
15583 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
15584 Remove unused parameter `fildes'.
15585 * process.c (read_process_output, send_process): Don't pass it.
15587 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15589 Fix previous change: the library cache is defined in w32.c.
15590 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
15591 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
15593 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15595 Implement dynamic loading of GnuTLS on Windows.

15632 * process.c: Include lisp.h before w32.h, not after.
15633 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
15634 instead of gnutls_record_check_pending.
15636 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
15638 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
15640 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

15686 rather than `XVECTOR (FOO)->size'.
15688 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
15689 inttypes.h, as a gnulib replacement is used if it not available in
15692 2011-04-21 Eli Zaretskii <eliz@gnu.org>

15717 produced by %s or %c overflows available buffer space. (Bug#8545)
15719 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
15721 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

15724 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15726 * w32.c (init_environment): Warn about defaulting HOME to C:\.
15728 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15730 * keyboard.c (Qdelayed_warnings_hook): Define.
15731 (command_loop_1): Run `delayed-warnings-hook'
15732 if Vdelayed_warnings_list is non-nil.
15733 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
15734 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
15736 2011-04-28 Eli Zaretskii <eliz@gnu.org>
15738 * doprnt.c (doprnt): Don't return value smaller than the buffer
15739 size if the message was truncated. (Bug#8545).
15741 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15743 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

15746 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15748 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
15750 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
15752 * makefile.w32-in: Update dependencies.
15754 2011-04-27 Eli Zaretskii <eliz@gnu.org>
15756 Improve `doprnt' and its usage. (Bug#8545)
15757 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
15758 `format_end'. Remove support for %l as a conversion specifier.
15759 Don't use xrealloc. Improve diagnostics when the %l size modifier
15760 is used. Update the commentary.
15762 * eval.c (verror): Simplify calculation of size_t.
15764 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
15767 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
15769 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
15772 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15774 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
15775 This makes this file independent of the recent pseudovector change.
15777 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
15779 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
15781 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
15782 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
15783 Remove unused local.
15784 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
15786 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
15787 GCC 4.6.0 optimizes based on type-based alias analysis.
15788 For example, if b is of type struct buffer * and v of type struct
15789 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
15790 != &v->size, and therefore "v->size = 1; b->size = 2; return
15791 v->size;" must therefore return 1. This assumption is incorrect
15792 for Emacs, since it type-puns struct Lisp_Vector * with many other
15793 types. To fix this problem, this patch adds a new type struct
15794 vectorlike_header that documents the constraints on layout of vectors
15795 and pseudovectors, and helps optimizing compilers not get fooled
15796 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
15797 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
15798 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
15800 (XSETPVECTYPE): Rewrite in terms of new macro.
15801 (XSETPVECTYPESIZE): New macro, specifying both type and size.
15802 This is a bit clearer, and further avoids the possibility of
15803 undesirable aliasing.
15804 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
15805 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
15806 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
15807 since Lisp_Subr is a special case (no "next" field).
15808 (ASIZE): Now uses header.size rather than size.
15809 All previous uses of XVECTOR (foo)->size replaced to use this macro,
15810 to avoid the hassle of writing XVECTOR (foo)->header.size.
15811 (struct vectorlike_header): New type.
15812 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
15813 object, to help avoid aliasing.
15814 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
15815 (SUBRP): Likewise, since Lisp_Subr is a special case.
15816 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
15817 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
15818 (struct Lisp_Hash_Table): Combine first two members into a single
15819 struct vectorlike_header member. All uses of "size" and "next" members
15820 changed to be "header.size" and "header.next".
15821 * buffer.h (struct buffer): Likewise.
15822 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
15823 * frame.h (struct frame): Likewise.
15824 * process.h (struct Lisp_Process): Likewise.
15825 * termhooks.h (struct terminal): Likewise.
15826 * window.c (struct save_window_data, struct saved_window): Likewise.
15827 * window.h (struct window): Likewise.
15828 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
15829 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
15830 * buffer.c (init_buffer_once): Likewise.
15831 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
15833 * process.c (Fformat_network_address): Use local var for size,
15836 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
15838 Make the Lisp reader and string-to-float more consistent (Bug#8525)
15839 * data.c (atof): Remove decl; no longer used or needed.
15840 (digit_to_number): Move to lread.c.
15841 (Fstring_to_number): Use new string_to_number function, to be
15842 consistent with how the Lisp reader treats infinities and NaNs.
15843 Do not assume that floating-point numbers represent EMACS_INT
15844 without losing information; this is not true on most 64-bit hosts.
15845 Avoid double-rounding errors, by insisting on integers when
15846 parsing non-base-10 numbers, as the documentation specifies.
15847 * lisp.h (string_to_number): New decl, replacing ...
15848 (isfloat_string): Remove.
15849 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
15850 (read1): Do not accept +. and -. as integers; this
15851 appears to have been a coding error. Similarly, do not accept
15852 strings like +-1e0 as floating point numbers. Do not report
15853 overflow for integer overflows unless the base is not 10 which
15854 means we have no simple and reliable way to continue.
15855 Break out the floating-point parsing into a new
15856 function string_to_number, so that Fstring_to_number parses
15857 floating point numbers consistently with the Lisp reader.
15858 (digit_to_number): Move here from data.c. Make it static inline.
15859 (E_CHAR, EXP_INT): Remove, replacing with ...
15860 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
15861 (string_to_number): New function, replacing isfloat_string.
15862 This function checks for valid syntax and produces the resulting
15863 Lisp float number too. Rework it so that string-to-number
15864 no longer mishandles examples like "1.0e+". Use strtoumax,
15865 so that overflow for non-base-10 numbers is reported only when
15866 there's no portable and simple way to convert to floating point.
15868 * textprop.c (set_text_properties_1): Rewrite for clarity,
15869 and to avoid GCC warning about integer overflow.
15871 * intervals.h (struct interval): Use EMACS_INT for members
15872 where EMACS_UINT might cause problems. See
15873 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
15874 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
15875 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
15877 (offset_intervals): Tell GCC not to worry about length overflow
15878 when negating a negative length.
15880 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
15881 (overrun_check_free): Likewise.
15883 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
15884 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
15887 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15888 (gnutls_make_error): Rename local to avoid shadowing.
15889 (gnutls_emacs_global_deinit): ifdef out; not used.
15890 (Fgnutls_boot): Use const for pointer to readonly storage.
15891 Comment out unused local. Fix pointer signedness problems.
15893 * lread.c (openp): Don't stuff size_t into an 'int'.
15894 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
15895 about possible signed overflow.
15897 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15898 (GDK_KEY_g): Don't define if already defined.
15899 (xg_prepare_tooltip): Avoid pointer signedness problem.
15900 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
15902 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
15903 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
15905 * xfns.c (Fx_window_property): Simplify a bit,
15906 to make a bit faster and to avoid GCC 4.6.0 warning.
15907 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
15909 * fns.c (internal_equal): Don't assume size_t fits in int.
15911 * alloc.c (compact_small_strings): Tighten assertion a little.
15913 Replace pEd with more-general pI, and fix some printf arg casts.
15914 * lisp.h (pI): New macro, generalizing old pEd macro to other
15915 conversion specifiers. For example, use "...%"pI"d..." rather
15916 than "...%"pEd"...".
15917 (pEd): Remove. All uses replaced with similar uses of pI.
15918 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
15919 * alloc.c (check_pure_size): Don't overflow by converting size to int.
15920 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
15921 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
15922 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
15923 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
15924 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
15926 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
15927 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
15928 * print.c (safe_debug_print, print_object): Likewise.
15929 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
15931 Use pI instead of if-then-else-abort. Use %p to avoid casts,
15932 avoiding the 0 flag, which is not portable.
15933 * process.c (Fmake_network_process): Use pI to avoid cast.
15934 * region-cache.c (pp_cache): Likewise.
15935 * xdisp.c (decode_mode_spec): Likewise.
15936 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
15937 behavior on 64-bit hosts with printf arg.
15938 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
15939 (x_stop_queuing_selection_requests): Likewise.
15940 (x_get_window_property): Don't truncate byte count to an 'int'
15943 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
15944 here, since it parses constructs like leading '-' and spaces,
15945 which are not wanted; and it overflows with large numbers.
15946 Instead, simply match F[0-9]+, which is what is wanted anyway.
15948 * alloc.c: Remove unportable assumptions about struct layout.
15949 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
15950 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
15951 (allocate_vectorlike, make_pure_vector): Use the new macros,
15952 plus offsetof, to remove unportable assumptions about struct layout.
15953 These assumptions hold on all porting targets that I know of, but
15954 they are not guaranteed, they're easy to remove, and removing them
15955 makes further changes easier.
15957 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
15958 This doesn't fix a bug but makes the code clearer.
15959 (string_overrun_cookie): Now const. Use initializers that
15960 don't formally overflow signed char, to avoid warnings.
15961 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
15962 can cause Emacs to crash when string overrun checking is enabled.
15963 (allocate_buffer): Don't assume sizeof (struct buffer) is a
15964 multiple of sizeof (EMACS_INT); it need not be, if
15965 alignof(EMACS_INT) < sizeof (EMACS_INT).
15966 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
15968 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
15970 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
15972 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
15974 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
15975 supposed to be handshaking. (Bug#8556)
15976 Reported by Paul Eggert <eggert@cs.ucla.edu>.
15978 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
15980 * lisp.h (Qdebug): List symbol.
15981 * eval.c (Qdebug): Restore global linkage.
15982 * keyboard.c (debug-on-event): New variable.
15983 (handle_user_signal): Break into debugger when debug-on-event
15984 matches the current signal symbol.
15986 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
15988 * alloc.c (check_sblock, check_string_bytes)
15989 (check_string_free_list): Convert to standard C.
15991 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
15993 * w32.c (emacs_gnutls_push): Fix typo.
15995 2011-04-25 Eli Zaretskii <eliz@gnu.org>
15997 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
15998 "cast to pointer from integer of different size".
16000 Improve doprnt and its use in verror. (Bug#8545)
16001 * doprnt.c (doprnt): Document the set of format control sequences
16002 supported by the function. Use SAFE_ALLOCA instead of always
16005 * eval.c (verror): Don't limit the buffer size at size_max-1, that
16006 is one byte too soon. Don't use xrealloc; instead xfree and
16009 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
16011 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
16014 * gnutls.c: Renamed global_initialized to
16015 gnutls_global_initialized. Added internals for the
16016 :verify-hostname-error, :verify-error, and :verify-flags
16017 parameters of `gnutls-boot' and documented those parameters in the

16501 * xdisp.c (redisplay_window): Simplify code, to make it more
16502 obvious that ignore_mouse_drag_p is not accessed if !defined
16503 USE_GTK && !defined HAVE_NS.
16505 * intervals.c: Make symbols static if they're not exported.

16508 * intervals.h (merge_interval_right, delete_interval): Remove decls.
16510 * insdel.c: Make symbols static if they're not exported.
16511 However, leave prepare_to_modify_buffer alone. It's never
16512 called from outside this function, but that appears to be a bug.
16513 (combine_after_change_list, combine_after_change_buffer):
16514 (adjust_after_replace, signal_before_change): Now static.
16515 (adjust_after_replace_noundo): Remove; unused.

16543 * font.c (font_close_object): Now static.
16544 * font.h (font_close_object): Remove.
16545 * fontset.c (FONTSET_OBJLIST): Remove.
16546 (free_realized_fontset) #if-0 the body, which does nothing.
16547 (face_suitable_for_char_p): #if-0, as it's never called.
16548 * fontset.h (face_suitable_for_char_p): Remove decl.
16549 * xfaces.c (face_at_string_position):
16550 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
16551 since 0 is always ASCII.
16553 * fns.c (weak_hash_tables): Now static.
16555 * fileio.c: Make symbols static if they're not exported.

16574 * editfns.c, lisp.h (get_operating_system_release): Remove.
16575 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
16576 worth the hassle of breaking this out.
16578 * xterm.c: Make symbols static if they're not exported.
16579 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

16682 * buffer.c (buffer_count): Remove unused var.

16686 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.

16691 * atimer.h (run_all_atimers): Remove; not exported.
16693 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
16694 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
16695 was inaccessible from Lisp.
16696 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
16697 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
16699 alloc.c: Import and export fewer symbols, and remove unused items.
16700 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
16702 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
16703 it's not optimized away by whole-program optimization.
16704 (message_enable_multibyte, free_misc): Remove.
16705 (catchlist, handlerlist, mark_backtrace):
16706 Declare only if BYTE_MARK_STACK.

16715 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
16716 (mark_backtrace): Define only if BYTE_MARK_STACK.
16717 * xdisp.c (message_enable_multibyte): Now static.
16719 Declare Lisp_Object Q* variables to be 'static' if not exported.
16720 This makes it easier for human readers (and static analyzers)
16721 to see whether these variables are used from other modules.
16722 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
16723 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
16724 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

16732 Remove decls of unexported vars.
16733 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
16735 * lisp.h (DEFINE_FUNC): Make sname 'static'.
16737 Make Emacs functions such as Fatom 'static' by default.
16738 This makes it easier for human readers (and static analyzers)
16739 to see whether these functions can be called from other modules.
16740 DEFUN now defines a static function. To make the function external
16741 so that it can be used in other C modules, use the new macro DEFUE.
16742 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
16743 (Finit_image_library):
16744 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
16745 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
16746 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
16747 Remove decls, since these functions are now static.
16748 (Funintern, Fget_internal_run_time): New decls, since these functions
16749 were already external.
16751 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
16752 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

16758 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
16759 Mark functions with DEFUE instead of DEFUN,
16760 if they are used in other modules.
16761 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
16762 decls for now-static functions.
16763 * buffer.h (Fdelete_overlay): Remove decl.
16764 * callproc.c (Fgetenv_internal): Mark as internal.
16765 * composite.c (Fremove_list_of_text_properties): Remove decl.

16772 * fileio.c (Fmake_symbolic_link): New forward static decl.
16773 * image.c (Finit_image_library): New forward static decl.
16774 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
16775 * intervals.h (Fprevious_property_change):
16776 (Fremove_list_of_text_properties): Remove decls.
16777 * keyboard.c (Fthis_command_keys): Remove decl.
16778 (Fcommand_execute): New forward static decl.

16794 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
16796 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
16799 2011-04-13 Eli Zaretskii <eliz@gnu.org>
16801 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
16802 when at ZV. (Bug#8487)
16804 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
16806 * charset.c (Fclear_charset_maps): Use xfree instead of free.
16808 * keyboard.c (parse_tool_bar_item): Likewise.
16809 * sound.c (sound_cleanup, alsa_close): Likewise.
16810 * termcap.c (tgetent): Likewise.
16811 * xfns.c (x_default_font_parameter): Likewise.
16812 * xsettings.c (read_and_apply_settings): Likewise.
16814 * alloc.c (overrun_check_malloc, overrun_check_realloc)
16815 (overrun_check_free): Protoize.
16817 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
16819 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
16820 since callers should never pass a negative size.
16821 Change the signature to match that of plain 'read' and 'write'; see
16822 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
16823 * lisp.h: Update prototypes of emacs_write and emacs_read.
16825 2011-04-11 Eli Zaretskii <eliz@gnu.org>
16827 * xdisp.c (redisplay_window): Don't try to determine the character
16828 position of the scroll margin if the window start point w->startp
16829 is outside the buffer's accessible region. (Bug#8468)
16831 2011-04-10 Eli Zaretskii <eliz@gnu.org>
16833 Fix write-region and its subroutines for buffers > 2GB.
16834 * fileio.c (a_write, e_write): Modify declaration of arguments and
16835 local variables to support buffers larger than 2GB.
16836 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
16838 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
16839 argument, local variables, and return value.
16841 * lisp.h: Update prototypes of emacs_write and emacs_read.
16843 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
16845 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
16847 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
16849 Fix more problems found by GCC 4.6.0's static checks.
16851 * xdisp.c (vmessage): Use a better test for character truncation.
16853 * charset.c (load_charset_map): <, not <=, for optimization,
16854 and to avoid potential problems with integer overflow.
16855 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
16856 * casetab.c (set_identity, shuffle): Likewise.
16857 * editfns.c (Fformat): Likewise.
16858 * syntax.c (skip_chars): Likewise.
16860 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
16861 This also lets GCC 4.6.0 generate slightly better loop code.
16863 * callint.c (Fcall_interactively): <, not <=, for optimization.
16864 (Fcall_interactively): Count the number of arguments produced,
16865 not the number of arguments given. This is simpler and lets GCC
16866 4.6.0 generate slightly better code.
16868 * ftfont.c: Distingish more carefully between FcChar8 and char.
16869 The previous code passed unsigned char * to a functions like
16870 strlen and xstrcasecmp that expect char *, which does not
16871 conform to the C standard.
16872 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
16873 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
16874 char * when the C standard requires it.
16876 * keyboard.c (read_char): Remove unused var.
16878 * eval.c: Port to Windows vsnprintf (Bug#8435).
16879 Include <limits.h>.
16880 (SIZE_MAX): Define if the headers do not.
16881 (verror): Do not give up if vsnprintf returns a negative count.
16882 Instead, grow the buffer. This ports to Windows vsnprintf, which
16883 does not conform to C99. Problem reported by Eli Zaretskii.
16884 Also, simplify the allocation scheme, by avoiding the need for
16885 calling realloc, and removing the ALLOCATED variable.
16887 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
16889 Remove invocations of doprnt, as Emacs now uses vsnprintf.
16890 But keep the doprint source code for now, as we might revamp it
16891 and use it again (Bug#8435).
16892 * lisp.h (doprnt): Remove.
16893 * Makefile.in (base_obj): Remove doprnt.o.
16894 * deps.mk (doprnt.o): Remove.
16896 error: Print 32- and 64-bit integers portably (Bug#8435).
16897 Without this change, on typical 64-bit hosts error ("...%d...", N)
16898 was used to print both 32- and 64-bit integers N, which relied on
16899 undefined behavior.
16900 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
16901 * lisp.h (error, verror): Mark as printf-like functions.
16902 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.

17052 This avoids several warnings with gcc -Wstrict-overflow.
17053 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
17054 directly, rather than having caller test rule sign. This avoids
17055 some unnecessary tests.
17056 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
17057 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
17058 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
17060 * xfont.c (xfont_text_extents): Remove var that was set but not used.
17061 (xfont_open): Avoid unnecessary tests.
17063 * composite.c (composition_gstring_put_cache): Use unsigned integer.

17075 since the condition is always true at first.
17077 * intervals.c (graft_intervals_into_buffer): Mark var as used.

17108 * eval.c (funcall_lambda): Rename local to avoid shadowing.
17110 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
17111 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
17112 can always succeed if overflow has undefined behavior.
17114 * search.c (boyer_moore, wordify): Remove vars set but not used.
17115 (wordify): Omit three unnecessary tests.
17117 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

17145 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
17146 that are set but not used.
17148 * xfns.c (make_invisible_cursor): Don't return garbage
17149 if XCreateBitmapFromData fails (Bug#8410).
17151 * xselect.c (x_get_local_selection, x_handle_property_notify):
17152 Remove vars that are set but not used.
17154 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
17155 (make_invisible_cursor): Initialize a possibly-uninitialized variable.

17176 that is set but not used.
17178 * print.c (print_object): Remove var that is set but not used.
17180 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
17181 The gnulib version avoids calling malloc in the usual case,
17182 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
17183 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
17184 * filelock.c (current_lock_owner): Likewise.
17185 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
17186 * sysdep.c: Include allocator.h, careadlinkat.h.
17187 (emacs_no_realloc_allocator): New static constant.
17188 (emacs_readlink): New function.
17189 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
17190 ../lib/careadlinkat.h.
17192 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
17194 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
17195 first non-nil return value).

17211 (get_per_char_metric): Remove parameter `f', unused since
17212 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

17256 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
17257 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
17258 (FletX, Flet): Obey lexical binding.
17259 (Fcommandp): Handle closures.
17260 (Feval): New `lexical' arg.
17261 (eval_sub): New function extracted from Feval. Use it almost
17262 everywhere where Feval was used. Look up vars in lexical env.
17264 (Ffunctionp): Move from subr.el.
17265 (Ffuncall): Handle closures.
17266 (apply_lambda): Remove `eval_flags'.
17267 (funcall_lambda): Handle closures and new byte-code-functions.
17268 (Fspecial_variable_p): New function.
17269 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
17270 but without exporting it to Lisp.
17272 * doc.c (Fdocumentation, store_function_docstring):
17273 * data.c (Finteractive_form): Handle closures.
17275 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
17278 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
17280 (exec_byte_code): New function extracted from Fbyte_code to handle new
17281 calling convention for byte-code-functions. Add new byte-codes.

17296 (redisplay_window): Even when falling back on "recentering",
17297 position point in the window according to scroll-conservatively,
17298 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
17300 (try_scrolling): When point is above the window, allow searching
17301 as far as scroll_max, or one screenful, to compute vertical
17302 distance from PT to the scroll margin position. This prevents
17303 try_scrolling from unnecessarily failing when
17304 scroll-conservatively is set to a value slightly larger than the
17305 window height. Clean up the case of PT below the margin at bottom
17306 of window: scroll_max can no longer be INT_MAX. When aggressive
17307 scrolling is in use, don't let point enter the opposite scroll
17308 margin as result of the scroll.
17309 (syms_of_xdisp) <scroll-conservatively>: Document the
17310 threshold of 100 lines for never-recentering scrolling.

17318 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
17319 (redisplay_internal): Remove parameter `preserve_echo_area',
17320 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
17322 * indent.c (Fvertical_motion):
17323 * window.c (window_scroll_pixel_based, Frecenter):
17324 Don't pass `need_y_p' to `move_it_by_lines'.

17363 instead of alloca (Bug#8344).
17365 * eval.c (Fbacktrace): Don't assume nargs fits in int.
17366 (Fbacktrace_frame): Don't assume nframes fits in int.
17368 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
17370 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
17373 * term.c (produce_glyphless_glyph): Remove unnecessary test.
17375 * cm.c (calccost): Turn while-do into do-while, for clarity.
17377 * keyboard.c (syms_of_keyboard): Use the same style as later
17378 in this function when indexing through an array. This also
17379 works around GCC bug 48267.
17381 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
17383 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

17386 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
17388 * keyboard.c, keyboard.h (num_input_events): Now size_t.
17389 This avoids undefined behavior on integer overflow, and is a bit
17390 more convenient anyway since it is compared to a size_t variable.
17392 Variadic C functions now count arguments with size_t, not int.
17393 This avoids an unnecessary limitation on 64-bit machines, which
17394 caused (substring ...) to crash on large vectors (Bug#8344).
17395 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
17396 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
17397 All variadic functions and their callers changed accordingly.
17398 (struct gcpro.nvars): Now size_t, not int. All uses changed.

17400 * editfns.c (general_insert_function): Likewise.
17401 * eval.c (struct backtrace.nargs, interactive_p)
17402 (internal_condition_case_n, run_hook_with_args, apply_lambda)
17403 (funcall_lambda, mark_backtrace): Likewise.
17404 * fns.c (concat): Likewise.
17405 * frame.c (x_set_frame_parameters): Likewise.
17406 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
17407 0 if not found, not -1. All callers changed.
17409 * alloc.c (garbage_collect): Don't assume stack size fits in int.
17410 (stack_copy_size): Now size_t, not int.
17411 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

17416 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
17417 All callers changed.
17419 * lisp.h (multibyte_char_to_unibyte):
17420 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
17421 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

17427 * xdisp.c (message_dolog, set_message_1): All callers changed.
17429 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
17431 * keyboard.c (safe_run_hook_funcall): New function.
17432 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
17433 don't set the hook to nil, but remove the offending function instead.
17434 (Qcommand_hook_internal): Remove, unused.
17435 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
17436 Vcommand_hook_internal.
17438 * eval.c (enum run_hooks_condition): Remove.
17439 (funcall_nil, funcall_not): New functions.
17440 (run_hook_with_args): Call each function through a `funcall' argument.
17441 Remove `cond' argument, now redundant.
17442 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
17443 (Frun_hook_with_args_until_failure): Adjust accordingly.
17444 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

17448 * dispextern.h (string_buffer_position): Remove declaration.
17450 * print.c (strout): Remove parameter `multibyte', unused since
17451 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
17453 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
17454 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
17455 All callers changed.
17457 * w32.c (_wsa_errlist): Use braces for struct initializers.
17459 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
17460 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
17461 All callers changed.

17463 used outside xdisp.c).
17464 (cursor_row_p): Remove parameter `w', unused since
17465 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

17467 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
17468 All callers changed.
17470 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
17472 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

17483 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
17485 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

17501 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
17503 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
17505 * w32.c (read_unc_volume): Use parameter `henum', instead of
17506 global variable `wget_enum_handle'.
17508 * keymap.c (describe_vector): Remove parameters `indices' and
17509 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

17524 * gtkutil.c (xg_maybe_add_timer):
17525 * keyboard.c (readable_events):
17526 * process.c (wait_reading_process_output):
17527 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
17529 * insdel.c (adjust_markers_gap_motion):
17530 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

17604 2011-03-23 Julien Danjou <julien@danjou.info>
17606 * term.c (Fsuspend_tty, Fresume_tty):
17607 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
17608 * window.c (temp_output_buffer_show):

17615 * callint.c (Fcall_interactively):
17616 * buffer.c (Fkill_all_local_variables):
17617 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
17619 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
17620 unconditionally since it does the check itself.
17622 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
17624 Fix more problems found by GCC 4.5.2's static checks.
17626 * coding.c (encode_coding_raw_text): Avoid unnecessary test
17627 the first time through the loop, since we know p0 < p1 then.
17628 This also avoids a gcc -Wstrict-overflow warning.
17630 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
17631 leading to a memory leak, possible in functions like
17632 load_charset_map_from_file that can allocate an unbounded number
17633 of objects (Bug#8318).
17635 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
17636 that could (at least in theory) be that large.
17638 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
17639 This is less likely to overflow, and avoids undefined behavior if
17640 overflow does occur. All callers changed. Use strtoul to scan
17641 for the unsigned long integer.
17642 (pint2hrstr): Simplify and tune code slightly.
17643 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
17645 * scroll.c (do_scrolling): Work around GCC bug 48228.
17646 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

17651 This also avoids a warning with gcc -Wstrict-overflow.
17653 * fileio.c (Fcopy_file): Report error if fchown or fchmod
17656 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
17658 * process.c (Fmake_network_process): Use socklen_t, not int,
17659 where POSIX says socklen_t is required in portable programs.
17660 This fixes a porting bug on hosts like 64-bit HP-UX, where
17661 socklen_t is wider than int (Bug#8277).
17662 (Fmake_network_process, server_accept_connection):
17663 (wait_reading_process_output, read_process_output):
17666 * process.c: Rename or move locals to avoid shadowing.

17673 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
17674 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
17676 Make tparam.h and terminfo.c consistent.
17677 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
17678 Include tparam.h instead, since it declares them.
17679 * cm.h (PC): Remove extern decl; tparam.h now does this.
17680 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
17681 * terminfo.c: Include tparam.h, to check interfaces.
17682 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
17683 (tparam): Adjust signature to match interface in tparam.h;
17684 this removes some undefined behavior. Check that outstring and len
17685 are zero, which they always are with Emacs.
17686 * tparam.h (PC, BC, UP): New extern decls.
17688 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
17689 (xftfont_open): Rename locals to avoid shadowing.
17691 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
17692 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
17693 (OTF_TAG_SYM): Omit macro if not needed.
17694 (ftfont_list): Remove unused local.
17695 (get_adstyle_property, ftfont_pattern_entity):
17696 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
17697 Rename locals to avoid shadowing.
17699 * xfont.c (xfont_list_family): Mark var as initialized.
17701 * xml.c (make_dom): Now static.
17703 * composite.c (composition_compute_stop_pos): Rename local to
17705 (composition_reseat_it): Remove unused locals.
17706 (find_automatic_composition, composition_adjust_point): Likewise.
17707 (composition_update_it): Mark var as initialized.
17708 (find_automatic_composition): Mark vars as initialized,
17709 with a FIXME (Bug#8290).
17711 character.h: Rename locals to avoid shadowing.
17712 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
17713 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
17714 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
17715 (BUF_DEC_POS): Be more systematic about renaming local temporaries
17716 to avoid shadowing.
17718 * textprop.c (property_change_between_p): Remove; unused.
17720 * intervals.c (interval_start_pos): Now static.
17722 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
17724 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
17725 Rename locals to avoid shadowing.
17727 * sound.c (wav_play, au_play, Fplay_sound_internal):
17728 Fix pointer signedness.
17729 (alsa_choose_format): Remove unused local var.
17730 (wav_play): Initialize a variable to 0, to prevent undefined
17731 behavior (Bug#8278).
17733 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
17735 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
17737 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
17738 clobbering (Bug#8298).
17739 * sysdep.c (sys_subshell): Likewise.
17740 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
17742 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
17743 This should get cleaned up, so that child_setup has the
17744 same signature on all platforms.
17746 * callproc.c (call_process_cleanup): Now static.
17747 (relocate_fd): Rename locals to avoid shadowing.
17749 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
17751 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
17752 not to be necessary, and produces flickering.
17754 2011-03-20 Glenn Morris <rgm@gnu.org>
17756 * config.in: Remove file.
17758 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
17760 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
17761 are now in src/globals.h.
17762 (syms_of_minibuf): Remove spurious & from previous change.

17772 * xfaces.c (Fx_load_color_file):
17773 Read color file from absolute filename (bug#8250).

17779 2011-03-17 Eli Zaretskii <eliz@gnu.org>
17781 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

17788 (sigchld_handler): Now static.
17790 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
17791 That way, the code declares only the vars that it needs.
17792 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
17793 * s/cygwin.h (PTY_ITERATION): Likewise.
17794 * s/darwin.h (PTY_ITERATION): Likewise.

17797 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
17798 * process.c (allocate_pty): Don't declare stb unless it's needed.
17800 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
17801 (CONSTANTLIM): Remove; unused.
17802 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
17803 Define only if needed.
17805 * unexelf.c (unexec): Name an expression,

17877 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
17878 some of which prompt warnings from gcc -Wbad-function-cast.
17879 (Fformat_time_string, Fencode_time, Finsert_char):
17880 (Ftranslate_region_internal, Fformat):

17908 (Fmemory_limit): Cast sbrk's returned value to char *.
17910 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
17911 avoids undefined behavior in theory.
17913 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
17915 Use functions, not macros, for up- and down-casing (Bug#8254).
17916 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
17917 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
17918 to use the following functions instead of these macros.
17919 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
17920 EMACS_INT, since callers assume the returned value fits in int.
17921 (upcase1): Likewise, for UPCASE_TABLE.
17922 (uppercasep, lowercasep, upcase): New static inline functions.
17923 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

17933 (regex_compile, re_match_2_internal): Mark locals as initialized.
17934 (RETALLOC_IF): Define only if needed.
17935 (WORDCHAR_P): Likewise. This one is never needed, but is used
17936 only in a comment talking about a compiler bug, so put inside
17937 the #if 0 of that comment.
17938 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
17939 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

17965 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
17966 New macros, so that the caller can use some names other than
17967 gcpro1, gcpro2, etc.
17968 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
17970 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
17971 argument, for consistency with GCPRO2_VAR, etc: it is now the
17972 prefix of the variable, not the variable itself. All uses
17974 * dired.c (directory_files_internal, file_name_completion):
17975 Rename locals to avoid shadowing.
17977 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
17978 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
17979 dired.c's scmp function, had undefined behavior.
17980 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
17981 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
17982 * buffer.h: ... to here, because these macros use current_buffer,
17983 and the new implementation with inline functions needs to have
17984 current_buffer in scope now, rather than later when the macros
17986 (downcase, upcase1): New static inline functions.
17987 (DOWNCASE, UPCASE1): Reimplement using these functions.
17988 This avoids undefined behavior in expressions like
17989 DOWNCASE (x) == DOWNCASE (y), which previously suffered
17990 from race conditions in accessing the global variables
17991 case_temp1 and case_temp2.
17992 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
17993 * lisp.h (case_temp1, case_temp2): Remove their decls.
17994 * character.h (ASCII_CHAR_P): Move from here ...
17995 * lisp.h: ... to here, so that the inline functions mentioned
17996 above can use them.
17998 * dired.c (directory_files_internal_unwind): Now static.
18000 * fileio.c (file_name_as_directory, directory_file_name):

18003 (file_name_as_directory): Use const pointers when appropriate.
18004 (Fexpand_file_name): Likewise. In particular, newdir might
18005 point at constant storage, so make it a const pointer.
18006 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
18007 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
18009 (Fset_file_times, Finsert_file_contents, auto_save_error):

18014 to avoid shadowing.
18016 * marker.c (bytepos_to_charpos): Remove; unused.
18018 * lisp.h (verify_bytepos, count_markers): New decls,
18019 so that gcc does not warn that these functions aren't declared.
18021 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
18022 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
18023 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
18024 (copy_text): Remove unused local var.
18026 * filelock.c (within_one_second): Now static.
18027 (lock_file_1): Rename local to avoid shadowing.
18029 * buffer.c (fix_overlays_before): Mark locals as initialized.
18030 (fix_start_end_in_overlays): Likewise. This function should be
18031 simplified by using pointers-to-pointers, but that's a different
18033 (switch_to_buffer_1): Now static.
18034 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
18035 (report_overlay_modification): Rename locals to avoid shadowing.

18038 Fix pointer signedness issue.
18039 (sys_subshell): Mark local as volatile if checking for lint,
18040 to suppress a gcc -Wclobbered warning that does not seem to be right.
18041 (MAXPATHLEN): Define only if needed.
18043 * process.c (serial_open, serial_configure): Move decls from here ...
18044 * systty.h: ... to here, so that they can be checked.
18046 * fns.c (get_random, seed_random): Move extern decls from here ...
18047 * lisp.h: ... to here, so that they can be checked.
18049 * sysdep.c (reset_io): Now static.
18050 (wait_for_termination_signal): Remove; unused.
18052 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

18055 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
18056 (DENSE_TABLE_SIZE): Remove; unused.
18057 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
18058 (describe_map_tree):
18059 Rename locals to avoid shadowing.
18061 * keyboard.c: Declare functions static if they are not used elsewhere.

18146 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
18147 These macros can no longer be used for assignment.

18208 For example, without this patch (encode-time 0 0 0 1 1
18209 1152921504606846976) returns the obviously-bogus value (-948597
18210 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
18211 reports time overflow. See
18212 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
18213 * deps.mk (editfns.o): Depend on ../lib/intprops.h.

18228 * editfns.c (time_overflow): New function, refactoring common code.
18229 (Fformat_time_string, Fdecode_time, Fencode_time):
