1 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4 that time stamps of directories could also be changed. Don't
5 request the too broad GENERIC_WRITE, only the more restrictive
6 FILE_WRITE_ATTRIBUTES access rights.
8 * fileio.c (Fset_file_times): Special-case ignoring errors for
9 directories only on MSDOS, not on MS-Windows.
11 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
13 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
15 2012-10-04 Eli Zaretskii <eliz@gnu.org>
17 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
18 see whether CreateFile failed.
20 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
22 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
23 to avoid similar races.
24 * keyboard.c (pending_signals): Now bool, not int.
26 Port timers to OpenBSD, plus check for timer failures.
27 OpenBSD problem reported by Han Boetes.
28 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
30 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
31 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
32 like OpenBSD, which has timer_settime but does not declare it.
33 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
34 whether to use itimerspec-related primitives. All uses of
35 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
37 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
39 * profiler.c (handle_profiler_signal): Fix a malloc race
40 that caused Emacs to hang on Fedora 17 when profiling Lisp.
42 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
44 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
46 2012-10-02 Eli Zaretskii <eliz@gnu.org>
48 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
49 consistent with the change in return value of 'safe_strsignal'.
51 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
53 Prefer plain 'static' to 'static inline' (Bug#12541).
54 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
55 (bidi_set_sor_type, bidi_push_embedding_level)
56 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

61 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
62 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
63 Now 'static', not 'static inline'.
65 Count overruns when profiling; change units to ns.
66 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
67 Give extra weight to samples after overruns, to attempt to count
68 the time more accurately.
69 (setup_cpu_timer): Change sampling interval units from ms to ns, since
70 the underlying primitives nominally do ns.
71 (Fprofiler_cpu_start): Document the change. Mention that
72 the sampling intervals are only approximate.
74 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
76 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
78 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
79 case for the special 0 coding-system.
81 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
82 (Fmake_overlay): Remove redundant tests.
83 (fix_start_end_in_overlays): Remove redundant recentering.
85 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
87 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
90 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
92 Fix a malloc race condition involving strsignal.
93 A signal can arrive in the middle of a malloc, and Emacs's signal
94 handler can invoke strsignal, which can invoke malloc, which is
95 not portable. This race condition bug makes Emacs hang on GNU/Linux.
96 Fix it by altering the signal handler so that it does not invoke
98 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
99 * process.c (status_message): Use const pointer, in case strsignal
100 is #defined to safe_strsignal.
101 * sysdep.c (sys_siglist, init_signals): Always define and
102 initialize a substitute sys_siglist if the system does not define
103 one, even if HAVE_STRSIGNAL.
104 (safe_strsignal): Rename from strsignal. Always define,
105 using sys_siglist. Return a const pointer.
106 * syssignal.h (safe_strsignal): New decl.
107 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
109 2012-10-01 Eli Zaretskii <eliz@gnu.org>
111 * w32proc.c (timer_loop): Fix code that waits for timer
112 expiration, to avoid high CPU usage.
114 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
116 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
117 (sweep_weak_table): Remove redundant prototypes.
119 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
121 * emacs.c: Move the inclusion of TERM_HEADER after including
122 windows.h on WINDOWSNT. This avoids compilation problems with
125 2012-10-01 Eli Zaretskii <eliz@gnu.org>
127 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
128 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
129 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
130 as the previous version used 'void *'.
132 * ralloc.c (ROUNDUP): Fix last change.
133 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
136 * w32proc.c <disable_itimers>: New static flag.
137 (init_timers): Initialize it to zero, after creating the critical
138 sections used by the timer threads.
139 (term_timers): Set to 1 before deleting the critical sections.
140 (getitimer, setitimer): If disable_itimers is non-zero, return an
141 error indication without doing anything. Reported by Fabrice
142 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
143 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
145 [!HAVE_SETITIMER]: Behave as the previous version that didn't
148 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
149 term_ntproc after all the other bookkeeping, to get timers working
152 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
154 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
155 Suggested by Juri Linkov in
156 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
158 Prefer plain 'static' to 'static inline' (Bug#12541).
159 With static functions, modern compilers inline pretty well by
160 themselves; advice from programmers often hurts as much as it helps.
161 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
162 this change shrinks the text size of the Emacs executable by 1.1%
163 without affecting CPU significantly in my benchmark.

244 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
246 Revert the FOLLOW-SYMLINKS change for file-attributes.
247 Doing it right would require several changes to Tramp, and there's
248 not enough time to get that tested before the freeze today.
249 * dired.c (directory_files_internal, Ffile_attributes):
252 * frame.c (x_report_frame_params): Port better to wider ints.

436 Suggested by Eli Zaretskii in
437 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.

446 Profiler improvements: more-accurate timers, overflow checks.
447 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,

455 (profiler_cpu_running): Now of that enum type, not bool.
456 All uses changed to store the new value.
457 (handle_profiler_signal): Rename from sigprof_handler_1,
458 for consistency with other handlers. Do not check whether
459 cpu_log is a hash-table if garbage collecting, since it
460 doesn't matter in that case.
461 (deliver_profiler_signal): Rename from sigprof_handler,
462 for consistency with other handlers.
463 (setup_cpu_timer): New function, with much of what used to be in
464 Fprofiler_cpu_start. Check for out-of-range argument.
465 Prefer timer_settime if available, and prefer
466 thread cputime clocks, then process cputime clocks, then
467 monotonic clocks, to the old realtime clock. Use make_timeval
468 to round more-correctly when falling back to setitimer.
469 (Fprofiler_cpu_start): Use it.
470 (Fprofiler_cpu_stop): Prefer timer_settime if available.
471 Don't assume that passing NULL as the 2nd argument of setitimer
472 is the same as passing a pointer to all-zero storage.
473 Ignore SIGPROF afterwards.
474 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
475 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
476 non-fatal signal handlers. Ignore SIGPROF on startup.
477 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
478 in profiler.c, since sysdep.c now uses it.
480 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
481 Suggested by Eli Zaretskii in
482 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

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

571 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
573 Prefer POSIX timers if available.
574 They avoid a race if the timer is too close to the current time.
575 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
576 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.

606 * w32proc.c (sys_signal): Handle all signals defined by the
607 MS-Windows runtime, not just SIGCHLD. Actually install the signal
608 handlers for signals supported by Windows. Don't override
609 term_ntproc as the handler for SIGABRT.
610 (sigaction): Rewrite to call sys_signal instead of duplicating its
612 (sys_kill): Improve commentary.
614 * w32.c (term_ntproc): Accept (and ignore) one argument, for
615 consistency with a signature of a signal handler. All callers
617 (init_ntproc): Accept an argument DUMPING. If dumping, don't
618 install term_ntproc as a signal handler for SIGABRT, as that
619 should be done by the dumped Emacs.
621 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
623 * w32select.c (term_w32select): Protect against repeated
624 invocation by setting clipboard_owner to NULL after calling
627 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
628 and term_ntproc to their modified signatures.
630 * character.c (char_string, string_char): Remove calls to
631 MAYBE_UNIFY_CHAR. See the discussion starting at

642 when encountering an unknown bytecode.
644 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
646 image.c, indent.c: Use bool for booleans.
647 * dispextern.h (struct image_type): Members valid_p, load, init
648 now return bool, not int. All uses changed.
649 * image.c: Omit unnecessary static decls.
650 (x_create_bitmap_mask, x_build_heuristic_mask):
651 Return void, not int, since callers don't care about the return value.

688 Move pid_t related decls out of lisp.h.
689 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
690 (interruptible_wait_for_termination):
691 Move these decls from lisp.h to syswait.h, since they use pid_t.
692 Needed on FreeBSD; see Herbert J. Skuhra in
693 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
694 * callproc.c: Include syswait.h.

740 2012-09-23 Eli Zaretskii <eliz@gnu.org>
742 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
743 fatal_error_backtrace.
745 * w32proc.c (sys_kill): Undo last change: don't do anything when
746 invoked to deliver SIGABRT to our own process. This is now
747 handled by emacs_raise.
749 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
751 * w32term.c (w32_read_socket): Remove leftover reference to
752 interrupt_input_pending.
754 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
756 Do not use SA_NODEFER.
757 Problem reported by Dani Moncayo in
758 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
760 * sysdep.c (emacs_abort): Do not reset signal handler.
761 * emacs.c (terminate_due_to_signal): Reset signal handler here.
762 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
763 wanted even on POSIXish hosts, and it doesn't work on Windows.
765 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
767 * xterm.c (x_term_init): Call fixup_locale before and after calling
768 gtk_init (Bug#12392).
770 2012-09-23 Chong Yidong <cyd@gnu.org>
772 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
773 Vdynamic_library_alist.
775 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
776 (Fgnutls_available_p): Caller changed.
778 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
779 (Flibxml_parse_xml_region): Likewise.
781 * dispextern.h (struct image_type): Remove arg from init function.
783 * image.c (Finit_image_library, lookup_image_type)

785 (init_xpm_functions, init_png_functions, init_jpeg_functions)
786 (init_tiff_functions, init_gif_functions, init_svg_functions):
787 Arglist and w32_delayed_load calling convention changed.
788 (gs_type): Remove init_gs_functions; there is no such function.
789 (valid_image_p, make_image): Fix caller to lookup_image_type.
791 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
793 Simplify and avoid signal-handling races (Bug#12471).
795 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
796 Avoid recursive loop if there's a fatal error in the function itself.
797 * atimer.c (pending_atimers):
798 * blockinput.h: Don't include "atimer.h"; no longer needed.
799 (interrupt_input_pending): Remove. All uses removed.
800 pending_signals now counts both atimers and ordinary interrupts.
801 This is less racy than having three separate pending-signal flags.
802 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
804 Rename from their upper-case counterparts BLOCK_INPUT,
805 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
806 INPUT_BLOCKED_P, and turn into functions. All uses changed.
807 This makes it easier to access volatile variables more accurately.
808 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
809 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
810 that's more reliable if the code is buggy and sets
811 interrupt_input_blocked to a negative value. All uses changed.
812 * atimer.c (deliver_alarm_signal):
813 Remove. No need to deliver this to the parent; any thread can
814 handle this signal now. All uses replaced by underlying handler.
815 * atimer.c (turn_on_atimers):
816 * dispnew.c (handle_window_change_signal):
817 * emacs.c (handle_danger_signal):
818 * keyboard.c (kbd_buffer_get_event):
819 Don't reestablish signal handler; not needed with sigaction.
820 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
822 Rework to avoid unnecessary accesses to volatile variables.
823 (UNBLOCK_INPUT_TO): Now a function.
824 (totally_unblock_input, unblock_input): New decls.
825 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
826 (init_data): Remove. Necessary stuff now done in init_signal.
827 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
828 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
829 (fatal_error_code): Remove; no longer needed.
830 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
831 it doesn't always backtrace. All uses changed. No need to reset
832 signal to default, since sigaction and/or die does that for us now.
833 Use emacs_raise (FOO), not kill (getpid (), FOO).
834 (main): Check more-accurately whether we're dumping.
835 Move fatal-error setup to sysdep.c
836 * floatfns.c: Do not include "syssignal.h"; no longer needed.
837 * gtkutil.c (xg_get_file_name, xg_get_font):
838 Remove no-longer-needed signal-mask manipulation.
839 * keyboard.c, process.c (POLL_FOR_INPUT):
840 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
841 * keyboard.c (read_avail_input): Remove.
842 All uses replaced by gobble_input.
843 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
844 (kbd_buffer_store_event_hold, gobble_input):
845 (record_asynch_buffer_change) [USABLE_SIGIO]:
846 (store_user_signal_events):
847 No need to mess with signal mask.
848 (gobble_input): If blocking input and there are terminals, simply
849 set pending_signals to 1 and return. All hooks changed to not
850 worry about whether input is blocked.
851 (process_pending_signals): Clear pending_signals before processing
852 them, in case a signal comes in while we're processing.
853 By convention callers now test pending_signals before calling us.
854 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
855 New functions, to support changes to blockinput.h.
856 (handle_input_available_signal): Now extern.
857 (reinvoke_input_signal): Remove. All uses replaced by
859 (quit_count): Now volatile, since a signal handler uses it.
860 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
861 All callers changed. Block SIGINT only if not already blocked.
862 Clear sigmask reliably, even if Fsignal returns, which it can.
863 Omit unnecessary accesses to volatile var.
864 (quit_throw_to_read_char): No need to restore sigmask.
865 * keyboard.c (gobble_input, handle_user_signal):
866 * process.c (wait_reading_process_output):
867 Call signal-handling code rather than killing ourselves.
868 * lisp.h: Include <float.h>, for...
869 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
870 (pending_signals): Now volatile.
871 (syms_of_data): Now const if IEEE floating point.
872 (handle_input_available_signal) [USABLE_SIGIO]:
873 (terminate_due_to_signal, record_child_status_change): New decls.
874 * process.c (create_process): Avoid disaster if memory is exhausted
875 while we're processing a vfork, by tightening the critical section
877 (send_process_frame, process_sent_to, handle_pipe_signal)
878 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
880 (send_process): No need for setjmp/longjmp any more, since the
881 SIGPIPE stuff is now gone. Instead, report an error if errno
883 (record_child_status_change): Now extern. PID and W are now args.
884 Return void, not bool. All callers changed.
885 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
886 Remove. All uses removed. This bug should be fixed now in a
888 (wait_for_termination_1): Use waitpid rather than sigsuspend,
889 and record the child status change directly. This avoids the
890 need to futz with the signal mask.
891 (process_fatal_action): Move here from emacs.c.
892 (emacs_sigaction_flags): New function, containing
893 much of what used to be in emacs_sigaction_init.
894 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
895 caught by emacs, to make races less likely.
896 (deliver_process_signal): Rename from handle_on_main_thread.
898 (BACKTRACE_LIMIT_MAX): Now at top level.
899 (thread_backtrace_buffer, threadback_backtrace_pointers):
901 (deliver_thread_signal, deliver_fatal_thread_signal):
902 New functions, for more-accurate delivery of thread-specific signals.
903 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
904 (deliver_arith_signal): Handle in this thread, not
905 in the main thread, since it's triggered by this thread.
906 (maybe_fatal_sig): New function.
907 (init_signals): New arg DUMPING so that we can be more accurate
908 about whether we're dumping. Caller changed.
909 Treat thread-specific signals differently from process-general signals.
910 Block all signals while handling fatal error; that's safer.
911 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
913 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
914 Ignore SIGPIPE unless batch.
915 (emacs_backtrace): Output backtrace for the appropriate thread,
916 which is not necessarily the main thread.
917 * syssignal.h: Include <stdbool.h>.
918 (emacs_raise): New macro.
919 * xterm.c (x_connection_signal): Remove; no longer needed
920 now that we use sigaction.
921 (x_connection_closed): No need to mess with sigmask now.
922 (x_initialize): No need to reset SIGPIPE handler here, since
923 init_signals does this for us now.
925 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
927 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
928 background rect may be larger (Bug#12245).
930 2012-09-23 Chong Yidong <cyd@gnu.org>
932 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
934 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
936 * .gdbinit: Just stop at fatal_error_backtrace.
937 See Stefan Monnier's request in
938 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
939 Remove no-longer-used query of system type.
941 2012-09-22 Chong Yidong <cyd@gnu.org>
943 * search.c (Freplace_match): Doc fix (Bug#12325).
945 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
947 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
948 (Fline_end_position): Doc fix.
950 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
952 2012-09-22 Chong Yidong <cyd@gnu.org>
954 * dispextern.h (struct image_type): Add new slot, storing a type
955 initialization function.
957 * image.c (define_image_type): Call the image initializer function
958 if it is defined. Arguments and return value changed.
959 (valid_image_p, make_image): Callers changed.
960 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
961 (gif_type, imagemagick_type, svg_type, gs_type):
962 Add initialization functions.
963 (Finit_image_library): Call lookup_image_type.
964 (CHECK_LIB_AVAILABLE): Macro deleted.
965 (lookup_image_type): Call define_image_type here, rather than via
966 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
967 (syms_of_image): Move define_image_type calls for xbm_type and
968 pbm_type to lookup_image_type.
970 2012-09-22 Eli Zaretskii <eliz@gnu.org>
972 * keyboard.c (timer_check_2): Move calculation of 'timers' and
973 'idle_timers' from here ...
974 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
975 lists, to avoid infloops when the timer does something stupid,
976 like reinvoke itself with the same or smaller time-out.
979 2012-09-22 Martin Rudalics <rudalics@gmx.at>
981 * window.c (Fsplit_window_internal): Handle only Qt value of
982 Vwindow_combination_limit separately.
983 (Qtemp_buffer_resize): New symbol.
984 (Vwindow_combination_limit): New default value.
987 2012-09-22 Eli Zaretskii <eliz@gnu.org>
989 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
990 the new overlay string. (Bug#10159)
992 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
994 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
995 or that fprintf is async-signal-safe. POSIX doesn't require
998 2012-09-22 Chong Yidong <cyd@gnu.org>
1000 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
1003 2012-09-22 Kenichi Handa <handa@gnu.org>
1005 * composite.c (composition_reseat_it): Handle the case that a
1006 grapheme cluster is not covered by a single font (Bug#12352).
1008 2012-09-21 Chong Yidong <cyd@gnu.org>
1010 * image.c (define_image_type): Avoid adding duplicate types to
1011 image_types (Bug#12463). Suggested by Jörg Walter.
1013 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1015 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
1016 (print_load_command_name): Add case LC_DATA_IN_CODE.
1017 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
1019 2012-09-21 Glenn Morris <rgm@gnu.org>
1021 * eval.c (Frun_hook_with_args_until_success)
1022 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
1024 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
1026 * fileio.c (Ffile_selinux_context): Only call freecon when
1027 lgetfilecon succeeded.
1028 (Fset_file_selinux_context): Likewise. (Bug#12444)
1030 2012-09-21 Eli Zaretskii <eliz@gnu.org>
1032 * xdisp.c (try_window_reusing_current_matrix): Under bidi
1033 reordering, locate the cursor by calling set_cursor_from_row; if
1034 that fails, clear the desired glyph matrix before returning a
1035 failure indication to the caller. Fixes leaving garbled display
1036 when fast scrolling with a down-key. (Bug#12403)
1037 (compute_stop_pos_backwards): Fix a typo that caused crashes while
1038 scrolling through multibyte text.
1040 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
1042 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
1043 calling mark_vectorlike since that's the one that marks the window.
1044 (mark_discard_killed_buffers): Mark the final cdr.
1045 * window.h (struct window): Move prev/next_buffers to the
1046 non-standard fields.
1047 * window.c (make_window): Initialize prev/next_buffers manually.
1049 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
1051 Omit unused arg EXPECTED from socket hooks.
1052 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
1053 * nsterm.m (ns_term_init):
1054 * termhooks.h (struct terminal.read_socket_hook):
1055 * w32inevt.c (w32_console_read_socket):
1056 * w32term.c (w32_read_socket):
1057 * xterm.c (XTread_socket):
1058 Omit unused arg EXPECTED. All callers changed.
1059 (store_user_signal_events): Return void, not int, since callers no
1060 longer care about the return value. All uses changed.
1062 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
1064 * w32gui.h (XParseGeometry): Do not declare.
1066 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
1068 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
1069 Ignore 'expected'. See Eli Zaretskii in
1070 <http://bugs.gnu.org/12471#8> (last line).
1072 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
1073 (XParseGeometry): Now static. Substitute extremal values for
1074 values that are out of range.
1076 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
1078 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
1080 * nsfns.m (XParseGeometry): Remove.
1081 (Fx_create_frame): Call x_set_offset to correctly interpret
1082 top_pos in geometry.
1084 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
1085 (Fx_parse_geometry): If there is a space in string, call
1086 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
1088 2012-09-17 Eli Zaretskii <eliz@gnu.org>
1090 * search.c (scan_buffer): Use character positions in calls to
1091 region_cache_forward and region_cache_backward, not byte
1092 positions. (Bug#12196)
1094 * w32term.c (w32_read_socket): Set pending_signals to 1, like
1095 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
1097 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
1098 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
1099 emacs_blocked_malloc, now deleted.
1101 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
1103 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
1104 The workaround was for improving performance on Solaris 2.4, but
1105 is getting in the way now. Emacs will still work if someone is
1106 still running Solaris 2.4 in a museum somewhere; Sun dropped
1107 support for Solaris 2.4 in 2003.
1108 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
1109 * process.c (create_process) [HAVE_WORKING_VFORK]:
1110 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
1111 since Emacs no longer uses vfork on that platform.
1113 2012-09-17 Glenn Morris <rgm@gnu.org>
1115 * emacs.c: Use COPYRIGHT.
1117 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
1119 Remove configure's --without-sync-input option (Bug#12450).
1120 When auditing signal-handling in preparation for cleaning it up,
1121 I found that SYNC_INPUT has race conditions and would be a real
1122 pain to fix. Since it's an undocumented and deprecated
1123 configure-time option, now seems like a good time to remove it.
1124 Also see <http://bugs.gnu.org/11080#16>.
1125 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
1126 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
1127 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
1128 (malloc_hysteresis):
1129 (check_depth) [XMALLOC_OVERRUN_CHECK]:
1130 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
1131 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
1132 (dont_register_blocks, bytes_used_when_reconsidered)
1133 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
1134 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
1135 [!SYSTEM_MALLOC && !SYNC_INPUT]:
1136 Remove. All uses removed.
1137 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
1138 implementation, one that depends on whether the new macro
1139 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
1141 * atimer.c (run_timers, handle_alarm_signal):
1142 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
1143 (handle_async_input, process_pending_signals)
1144 (handle_input_available_signal, init_keyboard):
1145 * nsterm.m (ns_read_socket):
1146 * process.c (wait_reading_process_output):
1147 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
1148 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
1150 * xterm.c (XTread_socket):
1152 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
1153 * eval.c (handling_signal): Remove. All uses removed.
1154 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
1155 All uses replaced with the SYNC_INPUT version.
1156 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
1158 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1161 * font.c (Ffont_shape_gstring): Remove unused local.
1163 2012-09-16 Glenn Morris <rgm@gnu.org>
1165 * Makefile.in (clean): No longer run nextstep's clean.
1167 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
1169 (ns-app): Move here from ns.mk, and simplify.
1170 (clean): Simplify nextstep entry.
1171 * ns.mk: Remove file.
1173 2012-09-17 Kenichi Handa <handa@gnu.org>
1175 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
1176 not covert the last few charactes.
1178 2012-09-16 Kenichi Handa <handa@gnu.org>
1180 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
1181 here, but just check the validity of glyphs in the glyph-string.
1183 2012-09-16 Martin Rudalics <rudalics@gmx.at>
1185 * window.c (Fwindow_parameter, Fset_window_parameter):
1186 Accept any window as argument (Bug#12452).
1188 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
1190 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
1191 to ns_term_init to avoid memory leak.
1193 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
1194 explicit retain/release.
1195 (ns_term_init): Only allow one display. Initialize outerpool and
1198 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1200 Port _setjmp fix to POSIXish hosts as well as Microsoft.
1201 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
1202 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
1203 the Microsoft problem in a different way, by altering ../nt/config.nt.
1205 2012-09-15 Eli Zaretskii <eliz@gnu.org>
1220 * w16select.c: Remove inclusion of setjmp.h, as it is now included
1221 by lisp.h. This completes removal of setjmp.h inclusion
1222 erroneously announced in the previous commit. (Bug#12446)
1224 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
1227 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
1228 not defined as a macro. The latter happens on MS-Windows.
1231 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1233 Port better to POSIX hosts lacking _setjmp (Bug#12446).
1234 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
1235 Some instances of '#include <setjmp.h>' removed, if the
1236 only reason for the instance was because "lisp.h" was included.
1237 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
1238 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
1239 and _longjmp with the new symbols. Emacs already uses _setjmp if
1240 available, so this change affects only POSIXish hosts that have
1241 sigsetjmp but not _setjmp, such as some versions of Solaris and
1242 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
1243 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
1244 (png_load_body) [HAVE_PNG]:
1245 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
1246 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
1247 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
1248 since PNG requires jmp_buf. This is the only exception to the
1249 general rule that we now use sys_setjmp and sys_longjmp.
1250 This exception is OK since this code does not change the signal
1251 mask or longjmp out of a signal handler.
1253 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
1255 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
1256 Include "syssignal.h", for 'main_thread'.
1258 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
1260 Avoid out-of-range marker position (Bug#12426).
1261 * insdel.c (replace_range, replace_range_2):
1262 Adjust markers before overlays, as suggested by comments.
1263 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
1264 Remove redundant check before calling offset_intervals.
1266 2012-09-14 Martin Rudalics <rudalics@gmx.at>
1268 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
1269 current buffer (Bug#12387).
1271 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
1273 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
1275 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
1277 Use a more backwards-compatible timer format (Bug#12430).
1278 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
1279 vector element, not from the 4th, since PSECS is now at the end.
1280 (Fcurrent_idle_time): Doc fix.
1282 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
1284 Function to mark objects and remove killed buffers at once.
1285 * alloc.c (discard_killed_buffers): Rename to ...
1286 (mark_discard_killed buffers) ... new name. Add marking
1287 of remaining objects. Fix comment. Adjust users.
1288 (mark_object): Do not touch frame buffer lists here.
1289 * frame.c (delete_frame): Reset frame buffer lists here.
1291 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
1293 Better workaround for GNOME bug when --enable-gcc-warnings.
1294 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
1295 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
1296 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
1298 Simplify SIGIO usage (Bug#12408).
1299 The code that dealt with SIGIO was crufty and confusing, e.g., it
1300 played tricks like "#undef SIGIO" but these tricks were not used
1301 consistently. Simplify mostly by not #undeffing standard symbols,
1302 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
1303 or not as we please) rather than "defined SIGIO" (standard symbol
1304 that we probably shouldn't #undef).
1305 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
1306 Modules that need it can include it.
1307 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
1308 * dispextern.h (ignore_sigio): New decl.
1309 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
1310 unconditionally, since it's now a no-op if !USABLE_SIGIO.
1311 * emacs.c (shut_down_emacs):
1312 * keyboard.c (kbd_buffer_store_event_hold):
1313 Use ignore_sigio rather than invoking 'signal' directly.
1314 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
1316 (FIONREAD, SIGIO): Do not #undef.
1317 (tty_read_avail_input): Use #error rather than a syntax error.
1318 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
1319 for I_PIPE, used by SETUP_SLAVE_PTY.
1320 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
1321 * sysdep.c (croak): Remove; no longer needed. This bit of
1322 temporary code, with Fred N. Fish's comment that it's temporary,
1323 has been in Emacs since at least 1992!
1324 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
1325 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
1326 * syssignal.h (croak): Remove decl.
1327 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
1328 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
1329 now that we're termios-only.
1330 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
1331 * term.c (dissociate_if_controlling_tty): Use #error rather than
1334 Work around GCC and GNOME bugs when --enable-gcc-warnings.
1335 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
1336 to work around GNOME bug 683906.
1337 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
1338 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
1339 This works around GCC bug 54561.
1341 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
1343 More fixes for 'volatile' and setjmp/longjmp.
1344 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
1345 * image.c (struct png_load_context) [HAVE_PNG]: New type.
1346 (png_load_body) [HAVE_PNG]:
1347 (jpeg_load_body) [HAVE_JPEG]:
1348 New function, with most of the old parent function's body.
1349 (png_load) [HAVE_PNG]:
1350 (jpeg_load) [HAVE_JPEG]:
1351 Invoke the new function, to avoid longjmp munging our locals.
1352 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
1353 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
1354 longjmp is passed 2, as the C standard doesn't guarantee this.
1355 Instead, store the failure code into mgr->failure_code.
1357 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
1359 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
1360 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
1361 (syms_of_keyboard): Remove support for unread-command-char.
1363 2012-09-12 Eli Zaretskii <eliz@gnu.org>
1365 * w32proc.c (sys_kill): If PID is our process ID and the signal is
1366 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
1367 violation. (Bug#12426)
1369 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
1371 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
1373 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
1375 * eval.c: Add `inhibit-debugger'.
1376 (Qinhibit_debugger): New symbol.
1377 (call_debugger): Bind it instead of Qdebug_on_error.
1378 (maybe_call_debugger): Test Vinhibit_debugger.
1379 (syms_of_eval): Define inhibit-debugger.
1380 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
1381 (syms_of_xdisp): Remove inhibit-debug-on-message.
1383 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
1385 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
1386 If a nonvolatile local variable is written before a _longjmp to
1387 the frame containing the variable, and is read after the _longjmp,
1388 the value read is indeterminate. Some local variables of type
1389 'struct handler' and 'struct catchtag' are used in this way, so
1390 mark each of their slots as volatile if the slot can be set before
1391 _longjmp and read afterwards.
1392 * lisp.h (struct handler): var and chosen_clause are now volatile.
1393 (struct catchtag): val, next, and pdlcount are now volatile.
1395 * bidi.c (bidi_push_it, bidi_pop_it):
1396 * fns.c (copy_hash_table):
1397 * image.c (define_image_type):
1398 * keyboard.c (kbd_buffer_store_event_hold):
1399 * process.c (Fprocess_send_eof):
1400 * xfaces.c (x_create_gc) [HAVE_NS]:
1401 * xgselect.c (xg_select):
1402 Prefer assignment to memcpy when either will do.
1404 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
1405 Use pointer-to-a-pointer to simplify and avoid a NILP check each
1406 time an item is removed. No need to mark this function 'inline';
1407 the compiler knows better than we do.
1409 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
1411 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
1412 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
1413 to change_frame_size (Bug#12388).
1414 (windowDidResize:): Pass YES to updateFrameSize.
1416 * nsterm.h: Add delay parameter to updateFrameSize.
1418 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
1420 Discard killed buffers from deleted window and frame objects.
1421 This reduces an amount of references to killed buffers and
1422 helps GC to reclaim them faster.
1423 * alloc.c (discard_killed_buffers): New function.
1424 (mark_object): Use it for deleted windows and frames.
1425 (mark_object): If symbol's value is set up for a killed buffer
1426 or deleted frame, restore it's global binding.
1427 * data.c (swap_in_global_binding): Add GC notice.
1428 (swap_in_symval_forwarding): Use convenient set_blv_where.
1429 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
1430 * window.h: ... to here.
1432 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
1434 Convenient macro to check whether the buffer is live.
1435 * buffer.h (BUFFER_LIVE_P): New macro.
1436 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
1437 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
1439 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1441 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
1442 composition cases (Bug#12364).
1444 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
1445 overhang of succeeding glyphs overlapping box cursor.
1447 * w32term.c (x_draw_glyph_string): Likewise.
1449 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
1451 Simplify, document, and port floating-point (Bug#12381).
1452 The porting part of this patch fixes bugs on non-IEEE platforms
1453 with frexp, ldexp, logb.
1454 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
1456 * floatfns.c: Simplify discussion of functions that Emacs doesn't
1457 support, by removing commented-out code and briefly listing the
1458 C89 functions excluded. The commented-out stuff was confusing
1459 maintenance, e.g., we thought we needed cbrt but it was commented out.
1460 (logb): Remove decl; no longer needed.
1461 (isfinite): New macro, if not already supplied.
1462 (isnan): Don't replace any existing macro.
1463 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
1464 are present on all C89 platforms.
1465 (Ffrexp): Do not special-case zero, as frexp does the right thing
1467 (Flogb): Do not use logb, as it doesn't have the desired meaning
1468 on hosts that use non-base-2 floating point. Instead, stick with
1469 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
1470 frexp, to avoid getting an unspecified result.
1472 * xdisp.c (Qinhibit_debug_on_message): Now static.
1474 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
1476 * nsterm.m (ns_update_begin): Set clip path to whole view by using
1477 NSBezierPath (Bug#12131).
1479 2012-09-10 Chong Yidong <cyd@gnu.org>
1481 * fns.c (Fdelq, Fdelete): Doc fix.
1483 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
1485 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
1486 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
1488 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
1490 * lisp.h (make_lisp_ptr): New macro to replace XSET.
1491 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
1494 2012-09-09 Eli Zaretskii <eliz@gnu.org>
1496 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
1497 left fringe if the window has a left margin. This avoids leaving
1498 traces of the cursor because its leftmost pixel is not drawn over.
1500 * dispnew.c (update_window_line): When the left margin area of a
1501 screen line is updated, set the redraw_fringe_bitmaps_p flag of
1502 that screen line. (Bug#12277)
1504 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
1506 Assume C89 or later for math functions (Bug#12381).
1507 This simplifies the code, and makes it a bit smaller and faster,
1508 and (most important) makes it easier to clean up signal handling
1509 since we can stop worring about floating-point exceptions in
1510 library code. That was a problem before C89, but the problem
1511 went away many years ago on all practical Emacs targets.
1512 * data.c, image.c, lread.c, print.c:
1513 Don't include <math.h>; no longer needed.
1514 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
1515 might be autoconfigured, as that never happens.
1517 * doprnt.c (DBL_MAX_10_EXP):
1518 * print.c (DBL_DIG):
1519 Remove. C89 or later always defines these.
1520 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
1521 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
1522 (arith_error, domain_error, domain_error2):
1523 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
1524 no longer needed -- we simply return what C returns. All uses removed.
1525 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
1527 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
1528 Remove. All uses expanded, as these macros are no longer used
1529 more than once and are now more trouble than they're worth.
1530 (Ftan): Use tan, not sin / cos.
1531 (Flogb): Assume C89 frexp.
1532 (fmod_float): Assume C89 fmod.
1533 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
1534 (init_floatfns): Remove. All uses removed.
1536 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1538 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
1539 compositeToPoint for OSX < 10.6 (Bug#12390).
1541 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
1543 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
1544 This produces more-accurate results.
1546 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1548 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
1549 changes (Bug#12088).
1551 2012-09-08 Chong Yidong <cyd@gnu.org>
1553 * syntax.c (Fstring_to_syntax): Doc fix.
1555 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1557 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
1558 in the internal border.
1559 (x_set_window_size): Remove static variables and their usage.
1560 (ns_redraw_scroll_bars): Fix NSTRACE arg.
1561 (ns_after_update_window_line, ns_draw_fringe_bitmap):
1562 Remove fringe/internal border adjustment (Bug#11052).
1563 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
1564 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
1565 (ns_fix_rect_ibw): Remove.
1566 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
1567 (ns_dumpglyphs_box_or_relief): Ditto.
1568 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
1570 (ns_dumpglyphs_image): Ditto.
1571 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
1573 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
1574 their usage. Add fringe_extended_p and its use as in other terms.
1575 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
1576 scroll bar was removed.
1577 (updateFrameSize): New function.
1578 (windowDidResize): Move code to updateFrameSize and call it.
1580 * nsterm.h (EmacsView): Add updateFrameSize.
1582 2012-09-07 Chong Yidong <cyd@gnu.org>
1584 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
1586 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
1588 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1590 More signal-handler cleanup (Bug#12327).
1591 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
1592 Problem introduced when merging patches. Noted by Eli Zaretskii in
1593 <http://bugs.gnu.org/12327#67>.
1594 * floatfns.c: Comment fix.
1595 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
1596 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
1597 and anyway the declaration is harmless even if SIGDANGER is not defined.
1598 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
1599 defined BROKEN_FIONREAD). systty.h formerly did this, but other
1600 source files not surprisingly expected syssignal.h to define, or
1601 not define, SIGIO, and it's cleaner to do it that way, for consistency.
1602 Include <sys/ioctl.h>, for FIONREAD.
1603 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
1604 This eliminates a problem whereby other files mysteriously had
1605 to include "syssignal.h" before including "systty.h" if they
1606 wanted to use "#ifdef SIGIO".
1608 2012-09-07 Eli Zaretskii <eliz@gnu.org>
1610 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
1612 * w32.c (sigemptyset): Empty the set.
1613 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
1615 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
1617 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
1619 * alloc.c (mark_buffer): Revert unsafe marking optimization.
1620 (mark_object): Likewise for frame objects.
1622 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1624 * syssignal.h (handle_on_main_thread): Always declare,
1625 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
1626 This ports to platforms without HAVE_PTHREAD.
1628 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1630 Signal-handler cleanup (Bug#12327).
1631 Emacs's signal handlers were written in the old 4.2BSD style with
1632 sigblock and sigmask and so forth, and this led to some
1633 inefficiencies and confusion. Rewrite these to use
1634 pthread_sigmask etc. without copying signal sets around. Also,
1635 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
1636 'signal', and instead use functions that do not attempt to take
1637 over the system name space. This patch causes Emacs's text
1638 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
1639 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
1640 Do not include <signal.h> or "syssignal.h", as these
1641 modules do not use signals.
1642 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
1643 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
1644 Do not include <signal.h>, as "syssignal.h" does that for us now.
1645 * atimer.c (sigmask_atimers): New function.
1646 (block_atimers, unblock_atimers): New functions,
1647 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
1649 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
1650 no longer needed here.
1651 * emacs.c (main): Inspect existing signal handler with sigaction,
1652 so that there's no need to block and unblock SIGHUP.
1653 * sysdep.c (struct save_signal): New member 'action', replacing
1654 old member 'handler'.
1655 (save_signal_handlers, restore_signal_handlers):
1656 Use sigaction instead of 'signal' to save and restore.
1657 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
1658 New function. All users of 'signal' modified to use set_sighandler
1659 if they're writeonly, and to use sys_signal if they're read+write.
1660 (emacs_sigaction_init, forwarded_signal): New functions.
1661 (sys_signal): Remove. All uses replaced by calls to sigaction
1662 and emacs_sigaction_init, or by direct calls to 'signal'.
1663 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
1664 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
1665 all uses replaced by pthread_sigmask etc. calls.
1666 * syssignal.h: Include <signal.h>.
1667 (emacs_sigaction_init, forwarded_signal): New decls.
1668 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
1669 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
1670 (sigmask, sys_sigmask): Remove; no longer needed.
1671 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
1672 (sigblock, sigunblock, sigfree):
1673 (sigsetmask) [!defined sigsetmask]:
1674 Remove. All uses replaced by pthread_sigmask.
1675 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
1676 no longer need to be replaced, and its typical old uses
1677 are now done via emacs_sigaction_init and sigaction.
1678 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
1679 (sys_sigdel): Remove; unused.
1680 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
1682 2012-09-06 Eli Zaretskii <eliz@gnu.org>
1684 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
1685 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
1687 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1689 Explicitly mark buffer_defaults and buffer_local_symbols.
1690 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
1691 mark_local_symbols here.
1692 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
1693 since special buffers aren't marked here any more.
1694 (allocate_buffer): Chain new buffer with all_buffers here...
1695 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
1697 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
1698 (syms_of_buffer): Remove staticpro of the above.
1699 (init_buffer_once): Set names for buffer_defaults and
1700 buffer_local_symbols.
1702 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1704 Use bool for booleans in font-related modules.
1705 * font.c (font_intern_prop, font_style_to_value)

1707 (generate_otf_features, font_check_otf_features, font_check_otf)
1708 (font_match_p, font_list_entities, font_at):
1709 * fontset.c (fontset_id_valid_p, reorder_font_vector
1710 (fontset_find_font, Fset_fontset_font)
1711 (face_suitable_for_char_p) [0]:
1712 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
1713 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
1714 (m17n_flt_initialized, ftfont_shape_by_flt):
1715 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
1716 * nsfont.m (nsfont_draw):
1717 * w32font.c (w32font_draw):
1718 * w32term.c (x_draw_glyphless_glyph_string_foreground):
1719 Use bool for booleans.
1720 * font.h: Adjust to above API changes.
1721 (struct font, struct font_driver, struct font_driver_list):
1722 Use bool for booleans.
1723 (struct font): Remove useless member encoding_type.
1725 * fontset.c, xftfont.c: Omit unnecessary static decls.
1727 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1729 * alloc.c (mark_object): Revert window marking code
1730 since it's unsafe for the Fset_window_configuration.
1732 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1734 Fix race conditions with signal handlers and errno (Bug#12327).
1735 Be more systematic about preserving errno whenever a signal
1736 handler returns, even if it's not in the main thread. Do this by
1737 renaming signal handlers to distinguish between signal delivery
1738 and signal handling. All uses changed.
1739 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
1740 * data.c (deliver_arith_signal): Rename from arith_error.
1741 * dispnew.c (deliver_window_change_signal): Rename from
1742 window_change_signal.
1743 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
1744 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
1745 * keyboard.c (deliver_input_available_signal): Rename from
1746 input_available_signal.
1747 (deliver_user_signal): Rename from handle_user_signal.
1748 (deliver_interrupt_signal): Rename from interrupt_signal.
1749 * process.c (deliver_pipe_signal): Rename from send_process_trap.
1750 (deliver_child_signal): Rename from sigchld_handler.
1751 * atimer.c (handle_alarm_signal):
1752 * data.c (handle_arith_signal):
1753 * dispnew.c (handle_window_change_signal):
1754 * emacs.c (handle_fatal_signal, handle_danger_signal):
1755 * keyboard.c (handle_input_available_signal):
1756 * keyboard.c (handle_user_signal, handle_interrupt_signal):
1757 * process.c (handle_pipe_signal, handle_child_signal):
1758 New functions, with the actual signal-handling code taken from the
1759 original respective signal handlers, sans the sporadic attempts to
1760 preserve errno, since that's now done by handle_on_main_thread.
1761 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
1762 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
1763 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1765 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1766 Move initialization of main_thread to sysdep.c's init_signals.
1767 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
1768 our usage, and simplifies the mainline code.
1769 (record_child_status_change): New static function, as a helper
1770 for handle_child_signal, and with most of the old child handler's
1772 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
1773 (handle_child_signal): Use the above.
1774 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1775 Moved here from emacs.c.
1776 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
1777 code moved here from emacs.c's main function.
1778 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
1779 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
1780 This lets callers save and restore errno properly.
1782 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1784 Remove redundant or unused things here and there.
1785 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
1786 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
1787 * editfns.c (Fcompare_buffer_substrings): Likewise.
1788 * frame.h (struct terminal, struct font_driver_list):
1789 Remove redundant declarations.
1790 * window.h (Qleft, Qright): Likewise.
1792 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1794 Do not mark objects from deleted buffers, windows and frames.
1795 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
1796 (mark_object): Likewise for windows and frames.
1798 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1800 * alloc.c (valid_lisp_object_p): Treat killed buffers,
1801 buffer_defaults and buffer_local_symbols as valid objects.
1802 Return special value to denote them.
1804 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1806 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
1807 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
1808 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
1809 (file_name_absolute_p, Fsubstitute_in_file_name):

1815 * filelock.c (boot_time_initialized, get_boot_time)
1816 (get_boot_time_1, lock_file_1, within_one_second):
1817 * floatfns.c (in_float):
1818 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
1819 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
1820 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
1821 * lisp.h (struct Lisp_Hash_Table.cmpfn):
1822 * window.c (compare_window_configurations):
1823 Use bool for booleans.
1824 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
1825 (Fdefault_file_modes): Now mode_t, not int, for modes.
1826 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
1827 (internal_delete_file): Now returns void, not a (boolean) int,
1828 since nobody was looking at the return value.
1829 * lisp.h, window.h: Adjust to above API changes.
1831 * xdisp.c (set_message): Simplify and reindent last change.
1833 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
1835 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
1837 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
1839 * eval.c (call_debugger): Make the function non-static so that we
1840 can call it from set_message.
1842 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
1843 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
1845 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1847 Give more-useful info on a fatal error (Bug#12328).
1848 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
1849 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
1850 of doing the work ourselves.
1851 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
1852 do most of the work.
1853 (fatal_error_backtrace): New function, taken from the guts
1854 of the old fatal_error_signal, but with a new option to output
1856 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
1857 info about the signal than just its number.
1858 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
1859 * sysdep.c: Include <execinfo.h>
1860 (emacs_backtrace): New function, taken partly from the previous
1861 code of the 'die' function.
1862 (emacs_abort): Call fatal_error_backtrace rather than abort.
1864 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
1866 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
1867 eager (load-time) macro-expansion.
1868 * lisp.mk (lisp): Add macroexp.
1870 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1872 Simplify redefinition of 'abort' (Bug#12316).
1873 Do not try to redefine the 'abort' function. Instead, redo
1874 the code so that it calls 'emacs_abort' rather than 'abort'.
1875 This removes the need for the NO_ABORT configure-time macro
1876 and makes it easier to change the abort code to do a backtrace.
1877 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
1878 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
1879 Remove; sysdep.c's emacs_abort now takes its place.
1880 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
1881 'abort' changed to use 'emacs_abort'.
1882 * msdos.c (dos_abort) [defined abort]: Remove; not used.
1883 (abort) [!defined abort]: Rename to ...
1884 (emacs_abort): ... new name.
1885 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
1886 the place of the old 'abort' in emacs.c.
1887 * w32.c, w32fns.c (abort): Do not #undef.
1888 * w32.c (emacs_abort): Rename from w32_abort.
1890 2012-09-04 Eli Zaretskii <eliz@gnu.org>
1892 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
1893 offsets[j].dv, since the y axis of the screen coordinates points
1894 down, while the y axis of the font definition coordinates points
1895 up. This fixes display of Arabic diacritics such as KASRA and
1896 KASRATAN. (Bug#11860)
1898 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1900 Be more systematic about _setjmp vs setjmp.
1901 * alloc.c (test_setjmp, mark_stack):
1902 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
1903 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
1904 (png_load, my_error_exit, jpeg_load):
1905 * process.c (send_process_trap, send_process):
1906 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
1907 The underscored versions are up to 30x faster on some hosts.
1908 Formerly, the code used setjmp+longjmp sometimes and
1909 _setjmp+_longjmp at other times, with no particular reason to
1910 prefer setjmp+longjmp.
1912 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
1914 Fix minor problem found by static checking.
1915 * buffer.c (Fdelete_all_overlays): Return nil.
1917 2012-09-03 Martin Rudalics <rudalics@gmx.at>
1919 * buffer.c (Fdelete_all_overlays): New function.
1921 2012-09-03 Chong Yidong <cyd@gnu.org>
1923 * gtkutil.c: Add extern decl for Qxft.
1925 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

1939 All callers changed.
1940 * eval.c (interactive_p): Omit always-true boolean argument
1941 EXCLUDE_SUBRS_P. All callers changed.
1942 * dispextern.h, lisp.h: Reflect above API changes.
1943 * firstfile.c (dummy): Use the address of 'main', whose signature
1944 won't change, instead of the address of 'initialize', whose
1945 signature just changed from int to bool.
1946 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
1947 * msdos.c (fatal_error_in_progress): ... from here.
1948 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
1950 (redisplay_internal, unwind_redisplay): Simply clear
1951 REDISPLAYING_P when unwinding, instead of saving its previous,
1952 always-false value and then restoring it.
1954 Clean up some extern decls.
1955 Mostly, this hoists extern decls out of .c files and into .h files.
1956 That way, we're more likely to catch errors if the interfaces change.
1957 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
1958 declare xg_mark_data.
1959 * dispextern.h (x_frame_parm_handlers):
1961 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

1977 * xfont.c (x_clear_errors):
1978 * xterm.c (x_frame_parm_handlers):
1979 Remove now-redundant extern decls.
1980 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
1981 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
1983 * xfaces.c: Remove unnecessary static decls.
1984 * xterm.c (updating_frame): Remove decl of nonexistent object.
1986 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
1987 when building globals.h, as the objects that are not built on
1988 this host are not needed to compile C files on this host.
1990 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
1992 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

2020 * keyboard.c (decode_timer):
2021 Use bool for boolean.
2022 * intervals.h, lisp.h, systime.h: Reflect above API changes.

2030 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
2032 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

2040 2012-09-01 Eli Zaretskii <eliz@gnu.org>
2042 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
2043 more than one grapheme cluster passed to the shaper: compute the
2044 offset adjustment values separately for each cluster. (Bug#11860)
2046 * image.c: Restore mistakenly removed inclusion of w32.h. Without
2047 it, GCC doesn't see prototypes of w32_delayed_load, and complains
2048 about implicit conversions from integer to pointer.
2050 2012-09-01 Daniel Colascione <dancol@dancol.org>
2052 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
2053 system used too early.
2055 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
2057 Better seed support for (random).

2093 window-system headers.
2095 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
2098 * keyboard.c: Include TERM_HEADER instead of listing all possible
2099 window-system headers.

2106 window system declarations.
2108 * frame.h: Move common functions here: set_frame_menubar,
2109 x_set_window_size, x_sync, x_get_focus_frame,
2110 x_set_mouse_position, x_set_mouse_pixel_position,
2111 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

2135 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
2137 Remove mark_ttys function and fix tty_display_info initialization.
2138 * lisp.h (mark_ttys): Remove prototype.
2139 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
2140 to mark_ttys because all possible values of 'top_frame' slot are
2141 the frames which are reachable from Vframe_list.
2142 * term.c (mark_ttys): Remove.
2143 (init_tty): Safely initialize 'top_frame' slot with Qnil.
2145 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>

2151 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
2152 bitfields from unsigned char to unsigned.

2167 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
2168 for GCC 4.7.1 x86-64.
2170 2012-08-30 Glenn Morris <rgm@gnu.org>
2172 * lread.c (init_lread): For out-of-tree builds, only add the
2173 source directory's site-lisp dir to the load-path if it exists,
2174 consistent with in-tree builds. (Bug#12302)
2176 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
2178 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

2187 (addString:row:): Remove return self, declare return value as void.
2188 (addSplit): Remove return self, declare return value as void.
2189 (clicked:): Remove return self, declare return value as void.
2190 Set dialog_return to button_values[seltag]. Code formatting change.

2192 Code formatting change.
2193 (timeout_handler:): Set timer_fired to YES.
2194 (runDialogAt:): Set timer_fired to NO.
2195 Handle click on close button as quit.
2197 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
2198 Add window_closed and button_values. Add void as return value for
2199 add(Button|String|Split). addButton takes int instead of Lisp_Object.
2200 Add process_dialog as new member.
2202 2012-08-28 Eli Zaretskii <eliz@gnu.org>
2204 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
2205 is not one of the heaps we manage. (Bug#12242)

2265 (change_frame_size_1, sit_for):
2266 Use bool for boolean.
2267 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
2268 and remove last int (actually boolean) argument, which was always 0.
2269 All callers changed.
2270 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
2271 * dispextern.h (struct composition_it): Use bool for boolean.
2272 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
2273 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
2274 * dired.c (file_name_completion):
2275 Use bool for boolean. (This was missed in an earlier change.)
2277 2012-08-27 Martin Rudalics <rudalics@gmx.at>
2279 * window.c (Fset_window_configuration): Revert first part of
2282 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
2284 * nsterm.h (NSPanel): New class variable dialog_return.
2286 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
2287 Initialize dialog_return.
2288 (windowShouldClose:): Use stop instead of stopModalWithCode.
2289 (clicked:): Ditto, and also set dialog_return (Bug#12258).
2290 (timeout_handler:): Use stop instead of abortModal. Send a dummy
2292 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
2295 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>
2297 * composite.c, data.c, dbusbind.c, dired.c: Use bool for booleans.
2298 * composite.c (find_composition, composition_gstring_p)

2305 * dbusbind.c (xd_in_read_queued_messages):
2306 * dired.c (directory_files_internal, file_name_completion):
2307 Use bool for booleans.
2308 * dired.c (file_name_completion):
2309 * process.h (fd_callback):
2310 Omit int (actually boolean) argument. It wasn't being used.
2312 * composite.h, lisp.h: Reflect above API changes.
2314 * cmds.c, coding.c: Use bool for booleans.
2315 * cmds.c (move_point, Fself_insert_command):

2335 (Fset_coding_system_priority):
2336 * fileio.c (Finsert_file_contents):
2337 Use bool for booleans.
2338 * coding.h, lisp.h: Reflect above API changes.
2339 * coding.c: Remove unnecessary static function decls.
2340 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
2341 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
2342 not a boolean 'int', since callers never look at the return value.
2343 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
2344 * coding.h (decoding_buffer_size, encoding_buffer_size)
2345 (emacs_mule_string_char): Remove unused extern decls.
2346 (struct iso_2022_spec, struct coding_system):
2347 Use 'unsigned int : 1' for boolean fields, since there's more than one.
2348 (struct emacs_mule_spec): Remove unused field 'full_support'.
2349 All initializations removed.
2350 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
2352 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
2354 Fix spare memory change (Bug#12286).
2355 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
2356 (valid_lisp_object_p): Likewise.
2358 2012-08-27 Martin Rudalics <rudalics@gmx.at>
2360 * window.c (Fset_window_configuration): Record any window's old
2361 buffer if it's replaced (see Bug#8789). If the new current
2362 buffer doesn't appear in the selected window, go to its old
2365 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
2367 Special MEM_TYPE_SPARE to denote reserved memory.
2368 * alloc.c (enum mem_type): New memory type.
2369 (refill_memory_reserve): Use new type for spare memory.
2370 This prevents live_cons_p and live_string_p from incorrect
2371 detection of uninitialized objects from spare memory as live.
2373 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
2376 * Makefile.in (.PHONY): versioclean -> versionclean.
2378 Remove unused external symbols.
2379 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
2380 * window.c (Qwindow_valid_p, decode_valid_window):
2381 Now static, not extern.
2382 * data.c (Qinterval): Remove; unused.
2383 (syms_of_data): Do not define 'interval'.
2384 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
2385 * window.h (decode_valid_window):
2388 * character.c, charset.c, chartab.c: Use bool for booleans.
2389 * character.c (lisp_string_width, string_count_byte8)
2390 (string_escape_byte8):

2397 (sub_char_table_set, sub_char_table_set_range)
2398 (char_table_set_range, optimize_sub_char_table)
2399 (map_sub_char_table):
2400 Use bool for boolean.
2401 * character.c (str_to_unibyte): Omit last boolean argument; it was
2402 always 0. All callers changed.
2403 * character.h, charset.h: Adjust to match previous changes.
2404 * character.h (char_printable_p): Remove decl of nonexistent function.
2405 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
2406 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
2407 are all boolean, so make them single-bit bitfields.
2409 * lisp.h (ASET): Remove attempt to detect side effects.
2410 It was meant to be temporary and it often doesn't work,
2411 because when IDX has side effects the behavior of IDX==IDX
2412 is undefined. See Stefan Monnier in
2413 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
2415 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
2417 * lisp.h (functionp): New function (extracted from Ffunctionp).
2418 (FUNCTIONP): Use it.
2419 * eval.c (Ffunctionp): Use it.
2421 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
2423 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
2424 as that's faster and simpler than static storage. Don't bother
2425 with the g_main_context_query overhead if g_main_context_pending
2426 says no events are pending.
2427 (gfds, gfds_size): Remove these static vars.
2428 (xgselect_initialize): Remove; no longer needed.
2429 All uses and decls removed.
2431 * emacs.c (fatal_error_signal_hook): Remove.
2432 All uses removed. This leftover from old code was always 0.
2434 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
2435 * casefiddle.c (casify_object, casify_region):
2436 * casetab.c (set_case_table):
2437 * category.c, category.h (word_boundary_p):
2438 * category.h (CHAR_HAS_CATEGORY):
2439 Use bool for booleans, instead of int.
2441 2012-08-25 Eli Zaretskii <eliz@gnu.org>
2443 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
2445 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
2447 On assertion failure, print backtrace if available.
2448 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
2449 (die) [ENABLE_CHECKING]: Print a backtrace if available.
2450 * Makefile.in (LIB_EXECINFO): New macro.
2453 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
2454 * bytecode.c (exec_byte_code):
2455 * callint.c (check_mark, Fcall_interactively):
2456 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
2457 (getenv_internal, sync_process_alive, call_process_exited):
2458 * lisp.h (USE_SAFE_ALLOCA):
2459 Use bool for booleans, instead of int.
2460 * lisp.h, process.h: Adjust prototypes to match above changes.
2461 * callint.c (Fcall_interactively): Don't assume the mark's
2462 offset fits in 'int'.
2464 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
2466 * buffer.c, buffer.h: Use bool for boolean.
2467 * buffer.c (reset_buffer_local_variables)
2468 (buffer_lisp_local_variables, Fset_buffer_modified_p)
2469 (Frestore_buffer_modified_p, Fset_buffer_multibyte):

2471 (overlay_touches_p, overlay_strings, Foverlay_put)
2472 (report_overlay_modification, call_overlay_mod_hooks):
2473 (mmap_enlarge, mmap_set_vars):
2474 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
2475 Use bool for booleans, instead of int.
2476 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
2477 since the 1-or-0 return value is always ignored anyway.
2478 (mmap_initialized_p):
2479 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
2480 * buffer.h, lisp.h: Adjust prototypes to match above changes.
2482 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
2484 * bidi.c: Use bool for boolean.
2485 This is a bit more readable, and makes the text segment of bidi.o
2486 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
2487 Presumably it's faster too.
2488 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
2490 (bidi_cache_find_level_change, bidi_cache_iterator_state)
2491 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
2492 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
2493 (bidi_explicit_dir_char, bidi_level_of_next_char)
2494 (bidi_find_other_level_edge, bidi_move_to_visually_next):
2495 Use bool for booleans, instead of int.
2496 * dispextern.h (bidi_init_it, bidi_paragraph_init)
2497 (bidi_unshelve_cache): Adjust decls to match code.
2499 2012-08-23 Martin Rudalics <rudalics@gmx.at>
2501 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
2504 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
2506 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
2507 * atimer.h: Include <stdbool.h>.
2509 2012-08-22 Dan Nicolaescu <dann@gnu.org>
2511 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
2512 compile time tests instead of run time tests on systems that do
2514 (FRAME_MAC_P): Remove leftover from deleted code.
2515 * frame.c (syms_of_frame): Remove leftover from deleted code.
2517 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
2519 * nsterm.m (insertText:): Don't clear modifiers if code is space.
2521 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
2523 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
2524 Otherwise, the compiler complains about (A?B:C) where B is void
2525 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
2526 (fontset_add): Return void, for FONTSET_ADD.
2528 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2530 * alloc.c: Use bool for booleans.
2531 (gc_in_progress, abort_on_gc)
2532 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
2533 (dont_register_blocks) [GC_MALLOC_CHECK]:
2534 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
2535 (check_string_bytes, make_specified_string, memory_full)
2536 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
2537 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
2538 (mark_stack, valid_pointer_p, make_pure_string)
2539 (Fgarbage_collect, survives_gc_p, gc_sweep):
2540 Use bool for booleans, instead of int.
2541 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
2542 Remove unused local.
2543 * alloc.c (PURE_POINTER_P):
2544 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
2545 * editfns.c (Fformat):
2546 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
2548 * fns.c (sweep_weak_table):
2549 * lisp.h (suppress_checking, push_message, survives_gc_p)
2550 (make_pure_string, gc_in_progress, abort_on_gc):
2551 * lread.c (readchar, read1):
2552 * print.c (Fprin1_to_string):
2553 * xdisp.c (push_message):
2554 Use bool for booleans affected directly or indirectly by
2557 Make recently-introduced setters macros.
2558 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
2559 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
2560 (set_fontset_default, set_fontset_fallback): Rename from their
2561 upper-case counterparts, and make them functions rather than macros.
2562 This is more consistent with the other recently-introduced setters.
2563 These don't need to be inline, since they're local.
2565 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
2567 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
2568 the loop (Bug#12247).
2570 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2572 * lisp.h (vcopy): Use memcpy rather than our own loop.
2573 This fixes a performance regression introduced by the recent
2574 addition of vcopy. This means 'vcopy' will need to be modified
2575 for a copying collector, but that's OK. Also, tighten the
2576 checking in the assertion.
2578 2012-08-21 Eli Zaretskii <eliz@gnu.org>
2580 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
2581 components for RTL text (Bug#11860). Adjust X-OFFSET of each
2582 non-base glyph for the width of the base character, according to
2583 what x_draw_composite_glyph_string_foreground expects.
2584 Generate WADJUST value according to composition_gstring_width's
2585 expectations, to produce correct width of the composed character.
2586 Reverse the sign of the DU offset produced by ScriptPlace.
2588 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2590 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
2592 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2594 Avoid direct writes to contents member of struct Lisp_Vector.
2595 * lisp.h (vcopy): New function to copy data into vector.
2596 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
2597 * fns.c (Ffillarray): Use ASET.
2598 * keyboard.c (timer_check_2): Use AREF and ASET.
2599 (append_tool_bar_item, Frecent_keys): Use vcopy.
2600 * lread.c (read_vector): Use ASET.
2601 * msdos.c (Frecent_doskeys): Use vcopy.
2602 * xface.c (Finternal_copy_lisp_face): Use vcopy.
2603 (Finternal_merge_in_global_face): Use ASET and vcopy.
2604 * xfont.c (xfont_list_pattern): Likewise.
2606 2012-08-21 Martin Rudalics <rudalics@gmx.at>
2608 * window.c (Fwindow_point): For the selected window always return
2609 the position of its buffer's point.
2610 (Fset_window_point): For the selected window always go in its
2611 buffer to the specified position.
2613 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2615 Setter macros for fontsets.
2616 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
2617 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
2618 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
2621 2012-08-20 Glenn Morris <rgm@gnu.org>
2623 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
2624 Don't assume that `ln -f' works.
2626 2012-08-20 Eli Zaretskii <eliz@gnu.org>
2628 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
2629 and later about non-assignments with no effect. See discussion at
2630 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
2633 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2635 Inline setter functions for Lisp_Objects slots of struct specbinding.
2636 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
2639 2012-08-20 Martin Rudalics <rudalics@gmx.at>
2641 * window.c (select_window): Always make selected window's buffer
2644 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2646 Use AREF and ASET for docstrings of category tables.
2647 * category.h (CATEGORY_DOCSTRING): Use AREF.
2648 (SET_CATEGORY_DOCSTRING): Use ASET.
2649 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
2651 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2653 Inline setter functions for hash table members.
2654 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
2655 (set_hash_hash, set_hash_index): Rename with _slot suffix.
2656 (set_hash_key_and_value, set_hash_index, set_hash_next)
2657 (set_hash_hash): New functions.
2658 * charset.c, fns.c: Adjust users.
2660 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2662 Inline getter and setter functions for per-buffer values.
2663 * buffer.h (per_buffer_default, set_per_buffer_default)
2664 (per_buffer_value, set_per_buffer_value): New functions.
2665 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
2666 * buffer.c, data.c: Adjust users.
2668 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
2670 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
2672 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
2674 Rely on <config.h> + <unistd.h> to declare 'environ',
2675 as gnulib does this if the system doesn't.
2676 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
2677 Remove declaration. MS-Windows declares it on stdlib.h which is
2678 included by conf_post.h.
2679 * emacs.c (environ) [DOUG_LEA_MALLOC]:
2680 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
2681 * vm-limit.c: Include <unistd.h>, for 'environ'.
2683 * unexaix.c, unexcoff.c: Include "mem-limits.h".
2684 (start_of_data): Remove decl; mem-limits.h provides it.
2686 * xdisp.c (handle_invisible_prop): Make it a bit faster
2687 and avoid a gcc -Wmaybe-uninitialized diagnostic.
2689 2012-08-19 Chong Yidong <cyd@gnu.org>
2691 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
2694 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
2696 * .gdbinit: Use call instead of set when calling a function in the
2699 * data.c (set_internal): Don't use set_blv_found.
2700 (Fkill_local_variable): Likewise.
2702 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>

3100 Use bool, not int, for Lisp booleans.
3101 This is more natural, and on my platform (GCC 4.7.1 x86-64) it
3102 makes Emacs a bit smaller and presumably a bit faster.

3104 (struct Lisp_Boolfwd, defvar_bool):
3105 * lread.c (defvar_bool): Use bool, not int, for Lisp booleans.

3570 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
3571 the code that sets Vexec_path run on MS-Windows.
3573 * lread.c (init_lread): Add comments to #ifdef's.
3575 * msdos.c (dos_set_window_size, IT_update_begin)
3576 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
3577 instead of direct references.
3579 2012-08-04 Paul Eggert <eggert@cs.ucla.edu>
3581 Export DEFAULT_REHASH_* to GDB.
3582 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
3583 Now constants, not macros.
3585 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
3587 Remove unnecessary casts involving pointers.
3588 These casts are no longer needed now that we assume C89 or later,
3589 since they involve casting to or from void *.
3590 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
3591 (make_pure_float, make_pure_vector):
3592 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

3601 (x_get_window_property, x_get_window_property_as_lisp_data):
3602 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
3603 Remove unnecessary pointer casts.
3604 * alloc.c (record_xmalloc): New function.
3605 * lisp.h (record_xmalloc): New decl.
3606 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
3607 more like a function. This is because the pointer cast is not
3608 needed. All uses changed.
3609 * print.c (print_string, print_error_message): Avoid length recalc.
3611 Improve fix for macroexp crash with debugging (Bug#12118).
3612 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
3613 ARRAY_MARK_FLAG when checking subscripts, because ASET is
3614 not supposed to be invoked from the garbage collector.
3615 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
3616 (gc_aset): New function, which is like ASET but can be
3617 used in the garbage collector.
3618 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
3619 (set_hash_index): Use it instead of ASET.

3631 (map_w32_filename): Improve commentary. Simplify switch.
3632 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
3633 headers (most versions of MinGW w32api don't).
3634 (get_security_info, create_symbolic_link)
3635 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
3637 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
3638 in the argument file name.

3641 (sys_rename): Diagnose renaming of a symlink when the user doesn't
3642 have the required privileges.
3643 (get_file_security_desc_by_name): Rename from
3644 get_file_security_desc.
3645 (stat_worker): New function, with most of the guts of 'stat', and
3646 with addition of handling of symlinks and support for 'lstat'.
3647 If possible, get file's attributes and security information by
3648 handle, not by name. Produce S_IFLNK bit for symlinks, when
3649 called from 'lstat'.
3650 (stat, lstat): New functions, call 'stat_worker'.
3651 (symlink, readlink, careadlinkat): Rewritten to create and resolve
3652 symlinks when the underlying filesystem supports them.
3654 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
3656 Fix macroexp crash on Windows with debugging (Bug#12118).
3657 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
3658 checking subscripts; problem introduced with the recent
3659 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
3660 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
3661 since it's used in non-static inline functions now.
3663 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
3664 Don't assume buffer size fits in 'int'. Remove unused local.

3678 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
3679 * alloc.c (LISP_INLINE):
3680 * buffer.c (BUFFER_INLINE):
3681 * category.c (CATEGORY_INLINE):
3682 * character.c (CHARACTER_INLINE):
3683 * charset.c (CHARSET_INLINE):
3684 * composite.c (COMPOSITE_INLINE):
3685 * dispnew.c (DISPEXTERN_INLINE):
3686 * sysdep.c (SYSTIME_INLINE):
3687 Define to EXTERN_INLINE, so that the corresponding functions
3688 are compiled into code.
3689 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
3690 (INLINE_HEADER_END): New macros.
3691 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

3711 hard-coding the path separator.
3713 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
3715 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
3716 This how ASET and AREF are supposed to work, and makes
3717 it easier to think about future improvements. See
3718 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
3719 * charset.h (set_charset_attr): New function.
3720 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
3721 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

4101 (w32_kbd_patch_key, key_event): Use the codepage returned by
4102 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

4134 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
4135 enumeration constants, as PURE and HEAP are too general, and clash
4136 with other headers and sources, such as gmalloc.c and the
4137 MS-Windows system headers. All users changed.
4139 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
4141 Revert last save_excursion_save and save_excursion_restore changes.
4142 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

4155 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
4156 arms of an 'if', not using conditional expressions; otherwise GDB
4157 complains about the types in the unevaluated arm when the argument
4158 is an integer literal.
4159 (xgetint): Simplify expression.
4160 * alloc.c (gdb_make_enums_visible): New constant. This ports to
4161 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
4162 Zaretskii in <http://bugs.gnu.org/12036#13>.
4163 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
4164 needed now that we have gdb_make_enums_visible.
4165 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
4166 (enum enum_USE_LSB_TAG):
4167 New enum types, packaging up enums that need to be exported to GDB.

4209 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
4210 emacs.c, as this is a more-suitable home. Had this been done earlier
4211 the fix for 12036 would have avoided some of the problems noted in
4212 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
4213 would have been more obvious.
4214 * emacs.c: Do not include <verify.h>; no longer needed.
4215 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
4216 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
4217 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

4223 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
4224 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
4225 not be usable in #if. This simplifies things.
4227 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
4229 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

4234 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
4235 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
4236 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
4237 Adjust to changes in lisp.h and emacs.c, by using
4238 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
4239 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
4240 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
4241 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
4242 instead of gdb_valbits.
4243 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
4244 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
4245 instead of gdb_array_mark_flag.
4246 (xboolvector): Get size from $->size, not $->header.size.
4247 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
4248 (xreload, hook-run, hookpost-run): Remove.
4249 * emacs.c: Include <verify.h>.
4250 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
4251 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
4253 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
4254 (gdb_USE_LSB_TAG): New enum constants.
4255 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
4256 Also define these as enum constants, so they're visible to GDB.
4257 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
4258 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
4259 as constants, so they're visible to GDB.

4262 Now enum constants, not macros, so they're visible to GDB.
4263 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
4264 more convenient now. All uses changed.
4265 (VALMASK) [USE_LSB_TAG]: Also define in this case.
4266 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
4268 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

4275 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
4276 add argument, tune behavior, and adjust all callers.
4278 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
4280 Use typedef for EMACS_INT, EMACS_UINT.
4281 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
4282 than macros. This simplifies debugging in the usual case, since
4283 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
4284 and it allows expressions involving EMACS_INT casts.
4285 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
4287 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

4299 Adjust buffer text indirection counters at the end of Fkill_buffer.
4300 * buffer.c (Fkill_buffer): Adjust indirection counters when the
4301 buffer is definitely dead. This should really fix an issue reported
4302 by Christoph Scholtes again. (Bug#12007).
4303 (init_buffer_once): Initialize indirection counters of
4304 buffer_defaults and buffer_local_symbols (for sanity and safety).
4306 2012-07-24 Eli Zaretskii <eliz@gnu.org>
4308 * xdisp.c (init_iterator): Don't compute dimensions of truncation
4309 and continuation glyphs on tooltip frames, leave them at zero.

4337 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
4339 Swap buffer text indirection counters in Fbuffer_swap_text.
4340 * buffer.c (Fbuffer_swap_text): Swap indirections too.
4341 This avoids crash reported by Christoph Scholtes at
4342 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
4344 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
4346 * nsmenu.m (Popdown_data): New struct.
4347 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
4349 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
4350 (initWithContentRect): Make imgView and contentView non-static
4351 and autorelease them. Also autorelease img and matrix (Bug#12005).
4352 (dealloc): Remove (Bug#12005).
4354 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
4356 Adjust consing_since_gc when objects are explicitly freed.

4369 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
4371 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
4372 as it's limited by the amount of memory, not by INT_MAX.
4374 2012-07-21 Eli Zaretskii <eliz@gnu.org>
4376 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
4377 in special-event-map. See the discussion at

4436 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
4437 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
4438 Adjust users accordingly.

4919 when the right fringe is turned off and variable-size fonts are
4920 used in the window. Move the code that appends a stretch glyph to
4921 produce_special_glyphs, so that it could be used for truncation
4922 and continuation glyphs alike.
4923 (produce_special_glyphs) [HAVE_WINDOW_SYSTEM]: Produce a stretch
4924 glyph of a suitably computed width, to align the special glyphs at
4925 the window margin. Code moved from display_line. (Bug#11832)

5100 * s/aix4-2.h (unix): Remove; no longer needed.
5102 EMACS_TIME simplification (Bug#11875).
5103 This replaces macros (which typically do not work in GDB)
5104 with functions, typedefs and enums, making the code easier to debug.
5105 The functional style also makes code easier to read and maintain.
5106 * systime.h: Include <sys/time.h> on all hosts, not just if
5107 WINDOWSNT, since 'struct timeval' is needed in general.

5120 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
5121 not functions. All uses rewritten to use the following, respectively:
5122 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
5123 (add_emacs_time, sub_emacs_time): New functions.
5124 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

5147 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
5148 Prefer snprintf to strncpy.
5149 * nsterm.m (ns_term_init):
5150 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
5151 * nsterm.m (ns_term_init):
5152 Avoid the need for strncpy, by using build_string or
5153 make_unibyte_string directly. Use dtoastr, not snprintf.
5154 * process.c (Fmake_network_process): Diagnose service names that
5155 are too long, rather than silently truncating them or creating
5156 non-null-terminated names.

5173 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
5174 where argument type is known to be a Lisp_Cons.

5229 O_RDONLY already includes it).
5231 Stop ns builds setting the EMACSLOADPATH environment variable.
5232 * nsterm.m (ns_load_path): Rename from ns_init_paths.
5233 Now it does not set EMACSLOADPATH, just returns the load-path string.

5235 * lread.c [HAVE_NS]: Include nsterm.h.
5236 (init_lread) [HAVE_NS]: Use ns_load_path.

5246 (ns_init_paths): Do not set EMACSPATH.

5306 Move marker debugging code under MARKER_DEBUG.
5307 * marker.c (MARKER_DEBUG): Move marker debugging code under
5308 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
5309 for bootstrap with --enable-checking (~3x slowdown reported

5354 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
5355 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
5356 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
5357 Fix pointer signedness problem.
5358 * xfaces.c (FRAME_X_FONT_TABLE):
5359 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
5361 2012-07-07 Glenn Morris <rgm@gnu.org>
5363 * lread.c (load_path_check): New function, split from init_lread.
5364 (init_lread): Reorganize. Motivation:
5365 If EMACSLOADPATH is set, check/warn about that rather than the
5366 defaults, which we are not going to use. Hence we can remove
5367 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
5368 Don't warn if site-lisp directories are missing.
5369 If not installed, start from a blank load-path, since
5370 PATH_LOADSEARCH refers to the eventual installation directories.
5372 2012-07-07 Eli Zaretskii <eliz@gnu.org>
5374 Support truncation and continuation glyphs on GUI frames, when
5375 fringes are disabled. (Bug#11832)
5376 * xdisp.c (init_iterator): Get dimensions of truncation and
5377 continuation glyphs even if on GUI frames.
5378 Adjust it->last_visible_x on GUI frames when the left or right fringes,
5379 or both, are absent.
5380 (start_display, move_it_in_display_line_to): Handle the case of a
5381 GUI frame without a fringe to display continuation or truncation
5383 (insert_left_trunc_glyphs): Support GUI frames: make sure
5384 truncation glyphs overwrite enough glyphs from the current line to
5385 have sufficient space in pixels.
5386 (display_line): Support truncation and continuation glyphs on GUI
5387 frames. If some spare pixels are left on the line after inserting
5388 the truncation glyphs, fill that space with a stretch glyph of a
5389 suitably computed width.
5391 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
5392 produce_glyphs, to support GUI sessions.
5394 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
5396 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
5398 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
5400 Do not require float-time's arg to fit in time_t (Bug#11825).
5401 This works better on hosts where time_t is unsigned, and where
5402 float-time is applied to the (negative) difference between two times.
5403 * editfns.c (decode_time_components): Last arg is now double *,
5404 not int *, and means to store all the result as a double, without
5405 worrying about whether the seconds part fits in time_t.
5406 All callers changed.
5407 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
5408 All callers changed.
5409 (Ffloat_time): Do not fail merely because the specified time falls
5410 outside of time_t range.
5412 2012-07-07 Glenn Morris <rgm@gnu.org>
5414 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
5415 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
5416 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
5418 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
5420 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
5421 Update dependencies.
5423 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
5425 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5427 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
5428 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
5429 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
5430 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
5431 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
5432 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
5434 * xfont.c (compare_font_names): Redo to omit the need for casts.
5436 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
5438 * xfns.c (Fx_change_window_property): Doc fix.
5439 * w32fns.c (Fx_change_window_property): Doc fix.
5441 * w32fns.c (Fx_window_property): Accept the same arguments as the
5442 X Windows version. Doc fix.
5443 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
5445 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
5446 Eli Zaretskii <eliz@gnu.org>
5448 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
5449 Windows-specific code from nt/config.nt moved here.
5450 Obsolete settings removed.
5452 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5454 * process.c: Avoid unnecessary calls to gettime.
5455 (wait_reading_process_output): Don't get the time of day
5456 when gobbling data immediately and not waiting, as there's no need
5457 for it in that case. This removes a FIXME.
5459 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
5461 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
5462 is defined (Bug#11768).
5464 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5466 Fix marker debugging code.
5467 * marker.c (byte_char_debug_check): Do not perform the check
5468 if buffer is not multibyte.
5469 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
5470 Call byte_char_debug_check with correct arguments.
5472 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5474 Compile marker debugging code only if ENABLE_CHECKING is defined.
5475 * marker.c (byte_char_debug_check, count_markers):
5476 Use only if ENABLE_CHECKING is defined.
5477 (byte_debug_flag): Remove.
5478 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
5479 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
5481 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5483 Avoid code repetition in marker-related functions.
5484 * marker.c (attach_marker): New function.
5485 (Fset_marker, set_marker_restricted, set_marker_both)
5486 (set_marker_restricted_both): Use it.
5487 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
5488 Consistently rename charno to charpos.
5489 (marker_position): Add eassert.
5490 (marker_byte_position): Convert to eassert.
5492 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5494 Simplify list operations in unchain_overlay and unchain_marker.
5495 * buffer.c (unchain_overlay): Simplify. Add comment.
5496 * marker.c (unchain_marker): Simplify. Fix comments.
5498 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5500 Introduce fast path for the widely used marker operation.
5501 * alloc.c (build_marker): New function.
5502 * lisp.h (build_marker): New prototype.
5503 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
5504 * composite.c (autocmp_chars): Likewise.
5505 * editfns.c (buildmark): Remove.
5506 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
5507 (save_restriction_save): Use build_marker.
5508 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
5509 * window.c (save_window_save): Likewise.
5511 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5513 Do not use Fdelete_overlay in delete_all_overlays
5514 to avoid redundant calls to unchain_overlay.
5515 * buffer.c (drop_overlay): New function.
5516 (delete_all_overlays, Fdelete_overlay): Use it.
5517 * minibuf.c (get_minibuffer): Fix comment.
5519 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5521 Port to OpenBSD 5.1 amd64.
5522 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
5523 This is needed for OpenBSD, and should be harmless on all BSD systems.
5524 Also, include <sys/sysctl.h>, as it should be available on all
5525 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
5526 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
5527 use p_pid member, not kp_proc.pid.
5529 2012-07-06 Glenn Morris <rgm@gnu.org>
5531 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
5533 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5535 More xmalloc and related cleanup.
5536 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
5537 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
5538 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

5541 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
5542 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
5543 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
5544 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
5546 Omit needless casts involving void * pointers and allocation.
5547 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
5548 as the former is more robust if P's type is changed.
5549 Prefer xzalloc to xmalloc + memset 0.
5550 Simplify malloc-or-realloc to realloc.
5551 Don't worry about xmalloc returning a null pointer.
5552 Prefer xstrdup to xmalloc + strcpy.
5553 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
5555 * keyboard.c (apply_modifiers_uncached): Prefer local array to
5556 alloca of a constant.
5558 2012-07-05 Eli Zaretskii <eliz@gnu.org>
5560 * xdisp.c (display_line): Fix horizontal pixel coordinates when
5561 hscroll is larger than the line width. Fixes long and futile
5562 looping inside extend_face_to_end_of_line (on a TTY) producing
5563 glyphs that are not needed and thrown away.
5565 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
5567 * marker.c (set_marker_restricted_both): Simplify by using
5570 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5572 * editfns.c (region_limit): Simplify by using clip_to_bounds.
5574 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
5576 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
5577 not defined (Bug#11768).
5578 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
5579 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
5580 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
5581 followed by gtk_box_set_homogeneous (Bug#11768).
5582 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
5583 (update_theme_scrollbar_width, xg_create_scroll_bar):
5584 Use gtk_scrollbar_new (Bug#11768).
5585 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
5586 (is_box_type): New function (Bug#11768).
5587 (xg_tool_item_stale_p): Call is_box_type.
5588 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
5589 with default display (Bug#11768).
5591 2012-07-05 Eli Zaretskii <eliz@gnu.org>
5593 * xdisp.c (window_hscroll_limited): New function.
5594 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
5595 coordinates when window's hscroll is set to insanely large
5598 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
5600 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
5601 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
5603 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
5606 * lisp.h (xzalloc): New prototype. Omit needless casts.
5607 * alloc.c (xzalloc): New function. Omit needless casts.

5659 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5661 * fileio.c (time_error_value): Check the right error number.
5662 Problem reported by Troels Nielsen in
5663 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
5665 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5667 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
5668 This should be fixed in a better way; see Eli Zaretskii in
5669 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
5670 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
5672 * fileio.c (time_error_value): Rename from special_mtime.
5673 The old name's problems were noted by Eli Zaretskii in
5674 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
5676 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
5677 This variable's comment says Emacs needs at least one GDB-visible
5678 symbol of type enum pvec_type, to work around GDB problems.
5679 The symbol's value doesn't matter.
5681 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
5682 that causes compilation to fail on pre-C99 compilers.
5684 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
5686 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
5687 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
5689 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5691 * buffer.c (init_buffer_once): Fix initialization of
5692 headers for buffer_defaults and buffer_local_symbols.
5693 Reported by Juanma Barranquero <lekktu@gmail.com>.
5695 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
5697 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
5698 * lisp.h (enum pvec_type): Use fewer bits.
5699 (PSEUDOVECTOR_SIZE_BITS): New constant.
5700 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
5701 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
5702 change in pvec_type.
5703 (PSEUDOVECTOR_TYPEP): New macro.
5704 (TYPED_PSEUDOVECTORP): Use it.
5705 * fns.c (internal_equal): Adapt code to extract pvectype.
5706 * emacs.c (gdb_pvec_type): Update type.
5707 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
5708 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
5709 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
5710 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
5711 (sweep_vectors): Use it. Use local var `total_bytes' instead of
5712 abusing vector->header.next.nbytes.
5713 (live_vector_p): Use PVEC_TYPE.
5714 (mark_object): Adapt code to extract pvectype. Use switch.
5716 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5718 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
5719 Tighten new eassert a bit.
5721 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5723 Fix compilation with --enable-gcc-warnings and -O1
5725 * doprnt.c (doprnt): Change type of tem to int, initialize
5726 to avoid compiler warning. Add eassert.
5727 * search.c (simple_search): Initialize match_byte to avoid
5728 compiler warning. Add eassert.
5730 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5732 Avoid weird behavior with large horizontal scrolls.
5733 Without this change, for example, large hscroll values would
5734 mess up Emacs's display on Fedora 15 x86, presumably due to
5735 overflows in int calculations in the display code.
5736 Also, if buffers had long lines, Emacs would freeze.
5737 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
5738 (set_window_hscroll): New function, containing the old guts of
5739 Fset_window_hscroll. Return the clipped value.
5740 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
5741 This avoids the need to check against PTRDIFF_MAX.
5743 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
5745 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5747 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
5749 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5751 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
5752 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
5753 since GCC 4.4.6 issues a bogus warning for them.
5755 Fix bugs in file timestamp newness comparisons.
5756 * fileio.c (Ffile_newer_than_file_p):
5757 * lread.c (Fload): Use full timestamp resolution of files,
5758 not just the 1-second resolution, so that files that are only
5759 slightly newer still count as newer.
5760 * fileio.c (Ffile_newer_than_file_p): Don't assume file
5761 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
5763 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
5765 * fileio.c: Improve handling of file time marker. (Bug#11852)
5766 (special_mtime): New function.
5767 (Finsert_file_contents, Fverify_visited_file_modtime):
5768 Use it to set special mtime values consistently.
5770 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
5772 * fileio.c (Finsert_file_contents): Properly handle st_mtime
5773 marker for non-existing file. (Bug#11852)
5775 2012-07-03 Glenn Morris <rgm@gnu.org>
5777 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
5778 and did not make it into globals.h).
5780 2012-07-03 Tom Tromey <tromey@redhat.com>

5826 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
5827 values which aren't power of 2.
5828 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
5829 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
5832 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
5834 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

5838 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5840 * alloc.c (allocate_vector_block): Remove redundant
5841 calls to mallopt if DOUG_LEA_MALLOC is defined.
5842 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
5843 avoid calls to mallopt if zero_vector is returned.
5845 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5847 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
5848 is enabled, avoid dereferencing NULL current_sblock if
5851 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5853 Cleanup basic buffer management.
5854 * buffer.h (struct buffer): Change layout to use generic vector
5855 marking code. Fix some comments. Change type of 'clip_changed'
5856 to bitfield. Remove unused #ifndef old.
5857 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
5858 (GET_OVERLAYS_AT): Fix indentation.
5859 (for_each_per_buffer_object_at): New macro.
5860 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

5863 * alloc.c (allocate_buffer): Adjust to match new layout of
5864 struct buffer. Fix comment.
5865 (mark_overlay): New function.
5866 (mark_buffer): Use it. Use mark_vectorlike to mark normal
5867 Lisp area of struct buffer.
5868 (mark_object): Use it. Adjust marking of misc objects
5869 and related comments.
5871 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
5873 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
5874 wrapper that is not needed because the wrapped code is a no-op (zero
5875 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
5876 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
5878 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
5880 * alloc.c (mark_buffer): Simplify. Remove prototype.
5881 (mark_object): Add comment. Reorganize marking of vector-like
5882 objects. Use CHECK_LIVE for all vector-like objects except buffers
5883 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
5884 Avoid redundant calls to mark_vectorlike for bool vectors.
5886 2012-06-30 Glenn Morris <rgm@gnu.org>
5888 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
5890 * epaths.in (PATH_SITELOADSEARCH): New.
5891 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
5892 This is rather than relying on --enable-locallisppath elements
5893 having "site-lisp" in their names. (Bug#10208#25, 11658)
5895 2012-06-30 Eli Zaretskii <eliz@gnu.org>
5897 * w32proc.c (sys_select): Accept and ignore one more argument.
5899 * w32.c (emacs_gnutls_pull): Call select with one more argument.
5901 * sysselect.h [DOS_NT]: Don't include sys/select.h.
5902 (pselect) [!MS_DOS]: Redirect to sys_select.
5904 * sysdep.c: Don't include dos.h and dosfns.h.
5906 * process.c (sys_select):
5907 * msdos.c (sys_select): Accept one more argument and ignore it.
5909 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
5910 adapt data types and code to that.
5913 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
5914 which clashes with the gnulib function of the same name.
5916 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
5918 * font.c (font_style_to_value, font_style_symbolic)
5919 (font_prop_validate_style): Add type checks for values in
5922 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
5924 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
5927 2012-06-29 Eli Zaretskii <eliz@gnu.org>
5929 * xdisp.c (try_window_id): Undo last change.
5931 * w32.c (getwd): Adjust commentary about startup_dir.
5932 (init_environment): Always call sys_access, even in non-MSVC
5933 builds. Don't chdir to the directory of the Emacs executable.
5934 This undoes code from 1997 which was justified by the need to
5935 "avoid conflicts when removing and renaming directories". But its
5936 downside was that every relative file name was being interpreted
5937 relative to the directory of the Emacs executable, which can never
5938 be TRT. In particular, it broke sys_access when called with
5939 relative file names.
5940 (sys_access): Map GetLastError to errno.
5942 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5944 * window.h (struct window): Change type of 'fringes_outside_margins'

5948 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
5951 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

5954 Add QUIT to make the loop interruptible.
5956 2012-06-29 Glenn Morris <rgm@gnu.org>
5958 * charset.c (init_charset): Make lack of etc/charsets fatal.
5960 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5962 * editfns.c (region_limit): Fix type mismatch.
5964 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5966 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
5967 undefined. Convert from xassert to eassert.
5968 * nsmenu.m: Convert from xassert to eassert.

5975 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
5977 Avoid integer overflow on scroll-left and scroll-right.
5978 * window.c (HSCROLL_MAX): New macro.
5979 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer

5984 * window.h (struct window): Change type of 'hscroll',
5985 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,

5987 Adjust users accordingly.
5988 * xdisp.c (try_cursor_movement): Replace type check with eassert.
5989 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
5990 from EMACS_INT to ptrdiff_t.
5991 (make_window): Omit redundant initialization.
5993 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

5997 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>

6066 * alloc.c (allocate_string): Omit intervals initialization.
6067 * alloc.c (make_uninit_multibyte_string): Initialize intervals
6068 as in make_pure_string and make_pure_c_string.

6126 a better opportunity to optimize away calls to strlen when the
6127 function is called with compile-time constant argument.
6128 * image.c (imagemagick_error): Convert to build_string.
6129 * w32proc.c (sys_spawnve): Likewise.

6132 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
6134 Use sprintf return value instead of invoking strlen on result.
6135 In the old days this wasn't portable, since some sprintf
6136 implementations returned char *. But they died out years ago and
6137 Emacs already assumes sprintf returns int.
6138 Similarly for float_to_string.
6139 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

6146 * xfns.c (syms_of_xfns):
6147 Use sprintf or float_to_string result to avoid need to call strlen.
6148 * data.c (Fnumber_to_string):
6149 Use make_unibyte_string, since the string must be ASCII.
6150 * lisp.h, print.c (float_to_string): Now returns int length.
6151 * term.c (produce_glyphless_glyph):
6152 Use sprintf result rather than recomputing it.
6154 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

6187 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

6190 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
6192 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
6193 instead of truncating it to 63 (admittedly a generous limit).
6195 * process.c: Fix spelling and caps in comments.
6197 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>

6253 * keyboard.c (kbd_buffer_get_event):

6316 Privately reported by Herbert J. Skuhra.
6317 [__FreeBSD__]: Remove "*/" typo after "#include".
6318 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
6319 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
6320 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
6321 Don't assume EMACS_TIME and struct timeval are the same type.
6323 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
6325 Support higher-resolution time stamps (Bug#9000).
6326 The time stamps are only nanosecond-resolution at the C level,
6327 since that's the best that any real-world system supports now.
6328 But they are picosecond-resolution at the Lisp level, as that's
6329 easy, and leaves room for future OS improvements.
6331 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
6334 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
6335 Don't get current time unless it's needed.
6337 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
6338 now provides it if it's absent.
6339 (start_atimer): Port to higher-res time stamps.
6340 Check for time stamp overflow. Don't get current time more
6341 often than is needed.
6343 * buffer.h (struct buffer): Buffer modtime now has high resolution.
6344 Include systime.h, not time.h.
6345 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
6347 * dired.c: Include stat-time.h.
6348 (Ffile-attributes): File times now have higher resolution.
6350 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
6351 (struct image): Timestamp now has higher resolution.
6353 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
6354 has at least microseconds now. All uses removed.
6355 (update_frame, update_single_window, update_window, update_frame_1)
6356 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
6357 (duration_to_sec_usec): Remove; no longer needed.
6359 * editfns.c (time_overflow): Now extern.
6360 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
6361 (float-time, Fformat_time_string, Fcurrent_time_string)
6362 (Fcurrent_time_zone): Accept and generate higher-resolution
6364 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
6365 (decode_time_components, lisp_seconds_argument): New functions.
6366 (make_time): Now static.
6367 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
6368 Report an error if the time is invalid, rather than having the caller
6371 * fileio.c: Include <stat-time.h>
6372 (Fcopy_file): Copy higher-resolution time stamps.
6373 Prefer to set the time stamp via a file descriptor if that works.
6374 (Fset_file_times, Finsert_file_contents, Fwrite_region)
6375 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
6376 (Fvisited_file_modtime, Fset_visited_file_modtime):
6377 Support higher-resolution time stamps.
6379 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
6381 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
6383 * image.c (prepare_image_for_display, clear_image_cache)
6384 (lookup_image): Port to higer-resolution time stamps.
6386 * keyboard.c (start_polling, bind_polling_period):
6387 Check for time stamp overflow.
6388 (read_char, kbd_buffer_get_event, timer_start_idle)
6389 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
6390 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
6391 Port to higher-resolution time stamps. Do not assume time_t is signed.
6392 (decode_timer): New function. Timers are now vectors of length 9,
6393 not 8, to accommodate the picosecond component.
6394 (timer_check_2): Use it.
6396 * nsterm.m (select_timeout, timeval_subtract): Remove.
6397 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
6398 as they're a bit more accurate and handle overflow better.
6399 (ns_select): Change prototype to be compatible with pselect.
6400 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
6401 * nsterm.h (ns_select): Adjust prototype.
6403 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
6404 us-resolution time stamps.
6405 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
6407 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
6409 * lisp.h (time_overflow): New decl.
6410 (wait_reading_process_output): First arg is now intmax_t, not int,
6411 to accommodate larger waits.
6413 * process.h (struct Lisp_Process.read_output_delay):
6414 Now counts nanoseconds, not microseconds.
6415 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
6417 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
6418 (wait_reading_process_output):
6419 Port to ns-resolution time stamps.
6420 (Faccept_process_output, wait_reading_process_output):
6421 Check for time stamp overflow. Do not assume time_t is signed.
6422 (select_wrapper): Remove; we now use pselect.
6423 (Fprocess_attributes): Now generates ns-resolution time stamps.
6425 * sysdep.c: Include utimens.h. Don't include utime.h
6426 or worry about struct utimbuf; gnulib does that for us now.
6427 (gettimeofday): Remove; gnulib provides a substitute.
6428 (make_timeval): New function.
6429 (set_file_times): Now sets ns-resolution time stamps.
6430 New arg FD; all uses changed.
6431 (time_from_jiffies, ltime_from_jiffies, get_up_time)
6432 (system_process_attributes):
6433 Now returns ns-resolution time stamp. All uses changed.
6434 Check for time stamp overflow.
6436 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
6437 provides a substitute now.
6439 * systime.h: Include timespec.h rather than sys/time.h and time.h,
6440 since it guarantees struct timespec.
6441 (EMACS_TIME): Now struct timespec, so that we can support
6442 ns-resolution time stamps.
6443 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
6444 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
6445 (EMACS_USECS): Remove.
6446 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
6447 so multiply the arg by 1000 before storing it.
6448 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
6450 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
6451 Port to ns-resolution time stamps.
6452 (EMACS_TIME_NEG_P): Remove; replaced by....
6453 (EMACS_TIME_SIGN): New macro.
6454 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
6455 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
6456 (set_file_times, make_time, lisp_time_argument): Adjust signature.
6457 (make_timeval, make_lisp_time, decode_time_components): New decls.
6458 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
6459 that it mishandled time_t overflow. You can't compare by subtracting!
6460 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
6461 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
6463 * term.c: Include <sys/time.h>.
6464 (timeval_to_Time): New function, for proper overflow wraparound.
6465 (term_mouse_position, term_mouse_click): Use it.
6467 * undo.c (record_first_change): Support higher-resolution time stamps
6469 (Fprimitive_undo): Use them when restoring time stamps.
6471 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
6472 (w32_get_internal_run_time):
6473 Port to higher-resolution Emacs time stamps.
6474 (ltime): Now accepts single 64-bit integer, as that's more convenient
6477 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
6479 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
6480 for compatibility with pselect. Support ns-resolution time stamps.
6482 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
6484 * xselect.c (wait_for_property_change, x_get_foreign_selection):
6485 Check for time stamp overflow, and support ns-resolution time stamps.
6487 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
6488 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
6489 (timeval_subtract): Remove; no longer needed.
6490 (XTflash, XTring_bell, x_wait_for_event):
6491 Port to ns-resolution time stamps. Don't assume time_t is signed.
6493 2012-06-22 Chong Yidong <cyd@gnu.org>
6495 * xdisp.c (x_consider_frame_title): Revert last change.
6497 2012-06-22 Eli Zaretskii <eliz@gnu.org>
6499 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
6500 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
6501 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
6502 staticidx goes up to 1597 out of 1600 = 0x640.)
6504 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
6506 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
6507 Otherwise, the umask might be mistakenly 0 while handling input signals.
6509 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
6511 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

6516 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
6517 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
6518 access to `contents' member of Lisp_Vector objects with AREF and ASET
6521 2012-06-19 Chong Yidong <cyd@gnu.org>
6523 * frame.c (delete_frame): When selecting a frame on a different
6524 text terminal, do not alter the terminal's top-frame.

6527 frame's selected window and its terminal's top-frame.
6528 (unwind_format_mode_line): Restore them.
6529 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
6531 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
6532 since tty frames can be explicitly named.
6533 (prepare_menu_bars): Likewise.
6535 * term.c (Ftty_top_frame): New function.
6537 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
6539 Port byte-code-meter to modern targets.
6540 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
6541 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
6542 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
6543 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
6544 (METER_1, METER_2): Simplify.
6546 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
6548 * data.c (Fdefalias): Return `symbol' (bug#11686).
6550 2012-06-18 Martin Rudalics <rudalics@gmx.at>
6552 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
6553 gets killed during executing of this function (Bug#11665).
6554 Try to always return Qt when the buffer has been actually killed.
6555 (Vkill_buffer_query_functions): In doc-string say that functions
6556 run by this hook should not change the current buffer.
6558 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
6560 Fix recently-introduced process.c problems found by static checking.
6561 * process.c (write_queue_push, write_queue_pop, send_process):
6562 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
6563 (write_queue_pop): Fix pointer signedness problem.
6564 (send_process): Remove unused local.
6566 2012-06-17 Chong Yidong <cyd@gnu.org>

6569 frames that are not on top.
6571 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
6573 * process.c (make_process): Initialize write_queue.
6574 (write_queue_push, write_queue_pop): New functions.

6578 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
6580 * lisp.h (eassert): Assume C89 or later.
6581 This removes the need for CHECK.
6582 (CHECK): Remove. Its comments about always evaluating its
6583 argument were confusing, as 'eassert' typically does not evaluate
6586 * coding.c (produce_chars): Use ptrdiff_t, not int.
6588 * xterm.c (x_draw_underwave): Check for integer overflow.
6589 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
6591 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
6593 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't
6594 referenced (Bug#11583).

6680 2012-06-16 Eli Zaretskii <eliz@gnu.org>
6682 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
6683 If all the glyphs of the glyph row came from strings, and we have no
6684 cursor positioning clues, put the cursor on the first glyph of the
6686 (handle_face_prop): Use chunk-relative overlay string index when
6687 indexing into it->string_overlays array. (Bug#11653)
6688 (set_cursor_from_row): Use the leftmost glyph as GLYPH_BEFORE, not

6711 (LISP_INT_TAG, case_Lisp_Int, LISP_STRING_TAG, LISP_INT_TAG_P)
6712 (LISP_INT1_TAG, enum Lisp_Type, XINT, XUINT, make_number):
6713 Simplify under the assumption that USE_2_TAGS_FOR_INTS is defined.
6714 (INTTYPEBITS): New macro, for clarity.
6715 (INTMASK, MOST_POSITIVE_FIXNUM): Use it.
6716 (LISP_INT1_TAG, LISP_STRING_TAG, LISP_INT_TAG_P):

6718 (TYPEMASK, XINT) [USE_LSB_TAG]: Remove unnecessary cast.
6719 (make_number) [!USE_LSB_TAG]: Use INTMASK; that's simpler.

6732 * lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct
6735 (XHASH, XTYPE, XINT, XUINT, make_number, XSET, XPNTR, XUNTAG):
6737 * emacs.c (gdb_use_struct): Rename from gdb_use_union.
6738 * .gdbinit: Check gdb_use_struct instead of gdb_use_union.
6739 * alloc.c (widen_to_Lisp_Object): Remove.
6740 (mark_memory): Use XIL instead of widen_to_Lisp_Object.
6741 * frame.c (delete_frame): Remove outdated comment.
6742 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
6743 USE_LISP_UNION_TYPE.
6744 (Fw32_unregister_hot_key): Likewise.
6745 (Fw32_toggle_lock_key): Likewise.
6746 * w32menu.c (add_menu_item): Likewise.

6753 2012-06-13 Glenn Morris <rgm@gnu.org>
6755 * s/usg5-4-common.h, src/s/unixware.h:
6756 Remove define/undef of HAVE_SYSV_SIGPAUSE (not used since 2010-05-04).
6758 * s/gnu.h (POSIX_SIGNALS): Remove (not used since 2010-05-04).
6760 2012-06-13 Paul Eggert <eggert@cs.ucla.edu>
6762 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
6763 * alloc.c (make_number) [!defined make_number]:
6764 Remove, as lisp.h always defines this now.
6765 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
6766 (roundup_size): Verify that it is a power of 2.
6767 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
6768 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
6769 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
6770 -DUSE_LSB_TAG=0, to override the automatically-selected default.
6771 USE_LSB_TAG now is always defined to be either 0 or 1.
6773 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
6774 code works fine either way, and efficiency is not a concern here,
6775 as the union type is for debugging, not for production.
6776 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
6777 Use an inline function on all platforms when using the union type,
6778 since this is simpler and 'static inline' can be used portably
6780 (LISP_INITIALLY_ZERO): New macro.
6781 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
6782 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

6922 * doprnt.c (doprnt): Truncate multibyte char correctly.
6923 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
6924 would mishandle a string argument "Xc" if X was a multibyte
6925 character of length 2: it would truncate after X's first byte
6926 rather than including all of X.
6928 2012-06-06 Chong Yidong <cyd@gnu.org>
6930 * buffer.c (word_wrap): Doc fix.

6983 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
6985 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
6988 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
6990 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
6992 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
6994 For a 'struct window', replace some Lisp_Object fields to
6995 bitfields where appropriate, remove unused fields.
6996 * window.h (struct window): Remove unused 'last_mark_x' and
6997 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
6998 change it's type from Lisp_Object to bitfield.
6999 Change type of 'force_start', 'optional_new_start',
7000 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
7001 fields from Lisp_Object to bitfield. Adjust users accordingly.
7003 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
7005 Pacify gcc -Wdouble-precision when using Xaw.

7007 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
7008 Use 'float' consistently, rather than 'float' in most places
7009 and 'double' in a couple of places.
7011 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7013 * xdisp.c (handle_stop): Detect whether we have overlay strings
7014 loaded by testing it->current.overlay_string_index to be
7015 non-negative, instead of checking whether n_overlay_strings is
7016 positive. (Bug#11587)
7018 2012-05-31 Chong Yidong <cyd@gnu.org>
7020 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
7022 * doc.c (Fsubstitute_command_keys): Doc fix.
7024 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7026 * search.c (search_buffer): Remove calls to
7027 r_alloc_inhibit_buffer_relocation, as it is now called by
7028 maybe_unify_char, which was the cause of relocation of buffer text
7031 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7033 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
7034 for the duration of call to load_charset, to avoid problems with
7035 callers of maybe_unify_char that access buffer text through C
7038 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
7039 decrement the inhibition flag, instead of just setting or
7042 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
7044 Remove obsolete '#define static' cruft.
7045 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
7046 This #undef was "temporary" in 2000; it is no longer needed
7047 now that '#define static' has gone away.
7048 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
7049 (gray_bitmap_bits): Remove; no longer needed.
7050 All uses replaced with definiens.
7051 * xterm.c: Include "bitmaps/gray.xbm".
7053 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
7055 Clean up __executable_start, monstartup when --enable-profiling.
7056 The following changes affect the code only when profiling.
7057 * dispnew.c (__executable_start): Rename from safe_bcopy.
7058 Define only on platforms that need it.
7059 * emacs.c: Include <sys/gmon.h> when profiling.
7060 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.

7062 (safe_bcopy): Remove decl; no longer has that name.
7063 (main): Coalesce #if into single bit of code, for simplicity.

7093 Do not create empty overlays with the evaporate property (Bug#9642).
7094 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
7095 Bug#9642, but explicitly check that the buffer the overlay would
7096 be moved to is live and rearrange lines to make sure that errors
7097 will not put the overlay in an inconsistent state.
7098 (Fdelete_overlay): Cosmetics.
7100 2012-05-28 Eli Zaretskii <eliz@gnu.org>
7102 * w32term.c (my_bring_window_to_top): New function.

7114 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
7116 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
7117 This avoids undefined behavior that might cause the eassert
7118 to not catch an out-of-range value.
7120 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
7122 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

7136 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
7137 Only r_alloc_inhibit_buffer_relocation needed to be added;
7138 the others were already declared.
7140 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
7141 before checking whether it's out of range. Put the check inside
7143 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
7145 2012-05-27 Ken Brown <kbrown@cornell.edu>

7153 defined on ralloc.c.
7155 * buffer.c [REL_ALLOC]: Remove prototypes of

7157 they are now on lisp.h.
7159 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
7161 * search.c (search_buffer): Use it to inhibit relocation of buffer
7162 text while re_search_2 is doing its job, because re_search_2 is
7163 passed C pointers to buffer text. (Bug#11519)
7165 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
7168 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator

7173 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
7176 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
7178 Fix coding-related core dumps with gcc -ftrapv.
7179 The code was computing A - B, where A and B are pointers, and B is
7180 random garbage. This can lead to core dumps on platforms that
7181 have special pointer registers, and it also leads to core dumps on
7182 x86-64 when compiled with gcc -ftrapv. The fix is to compute
7183 A - B only when B is initialized properly.
7184 * coding.c (coding_set_source, coding_set_destination): Return void.
7185 (coding_change_source, coding_change_destinations): New functions,
7186 with the old behaviors of coding_set_source and coding_set_destination.

7191 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
7193 2012-05-26 Eli Zaretskii <eliz@gnu.org>
7195 Extend mouse support on W32 text-mode console.
7196 * xdisp.c (draw_row_with_mouse_face):
7197 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
7199 * w32console.c: Include window.h.
7200 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
7202 (initialize_w32_display): Initialize mouse-highlight data.
7204 * w32inevt.c: Include termchar.h and window.h.
7205 (do_mouse_event): Support mouse-autoselect-window. When the mouse
7206 moves, call note_mouse_highlight. If help_echo changed, call
7207 gen_help_event to produce help-echo message in the echo area.
7208 Call clear_mouse_face if mouse_face_hidden is set in the mouse
7211 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
7213 * lread.c (read1): Simplify slightly to avoid an overflow warning
7214 with GCC 4.7.0 on x86-64.
7216 2012-05-26 Eli Zaretskii <eliz@gnu.org>
7218 * bidi.c (bidi_mirror_char): Revert last change: an int is
7219 definitely wide enough here.

7233 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7234 (allocate_pseudovector):
7235 Use int, not EMACS_INT, where int is wide enough.
7236 (inhibit_garbage_collection, Fgarbage_collect):
7237 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7238 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
7239 int might not be wide enough.

7256 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
7257 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7258 (validate_region): Omit unnecessary test for b <= e,
7259 since that's guaranteed by the previous test.

7261 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
7262 (report_overlay_modification):
7263 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7264 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

7266 after the EMACS_INT -> ptrdiff_t change.
7267 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
7268 * buffer.h: Adjust decls to match defn changes elsewhere.

7273 not int, to avoid needless 32-bit limit on 64-bit hosts.
7274 (exec_byte_code): Use tighter memory-full test, one that checks
7275 for alloca overflow. Don't compute the address of the object just
7276 before an array, as that's not portable. Use EMACS_INT, not
7277 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
7278 * callint.c (Fcall_interactively):
7279 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

7292 (casify_object): Avoid integer overflow when overallocating buffer.
7293 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

7296 * category.h (CATEGORYP): Don't assume arg is nonnegative.
7297 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
7298 integers are now checked earlier. All uses replaced with XINT.
7300 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7301 For CCL_MapSingle, check that content and value are in int range.

7303 Check that Vcode_version_map_vector is a vector.
7304 (resolve_symbol_ccl_program): Check that vector header is in range.
7305 Always copy the vector, so that we can check its contents reliably
7306 now rather than having to recheck each instruction as it's being
7307 executed. Check that vector words fit in 'int'.
7308 (ccl_get_compiled_code, Fregister_ccl_program)
7309 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for

7336 Don't rely on undefined behavior with signed left shift overflow.
7337 Don't assume unsigned int fits into fixnum, or that fixnum fits
7338 into unsigned int. Don't require max_code to be a valid fixnum;
7339 that's not true for gb10830 4-byte on a 32-bit host. Allow
7340 invalid_code to be a cons, for the same reason. Require code_offset
7341 to be a character. Avoid int overflow if max_char is close
7343 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
7344 this is intended anyway and avoids some undefined behavior.
7345 (load_charset_map): Pass unsigned, not int, as 2nd arg of
7346 INDEX_TO_CODE_POINT, as that's what it expects.
7347 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
7348 * charset.h (DECODE_CHAR): Return int, not unsigned;
7349 this is what was intended anyway, and it avoids undefined behavior.
7350 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
7351 integer-overflow issues.
7352 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
7353 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
7354 where the argument is EMACS_INT, and this behavior is not intended.
7355 * chartab.c (Fmake_char_table, Fset_char_table_range)
7356 (uniprop_get_decoder, uniprop_get_encoder):
7357 Don't assume fixnum fits in int.
7358 * cmds.c (move_point): New function, that does the gist of
7359 Fforward_char and Fbackward_char, but does so while checking
7360 for integer overflow more accurately.
7361 (Fforward_char, Fbackward_char): Use it.
7362 (Fforward_line, Fend_of_line, internal_self_insert)
7363 (internal_self_insert):
7364 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

8023 2012-05-25 Glenn Morris <rgm@gnu.org>
8025 * lisp.mk (lisp): Update for more files being compiled now.
8027 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
8029 * lread.c: Remove `read_pure' which makes no difference.
8030 (read_pure): Remove var.
8031 (unreadpure): Remove function.
8032 (readevalloop): Don't call read_list with -1 flag.
8033 (read1, read_vector): Don't test read_pure any more.

8047 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
8050 This directory predates autoconf and is no longer needed nowadays.
8051 Move its few remaining bits of functionality to where they're needed.
8052 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

8061 (EMACS_UINT): Define unconditionally now.
8062 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
8063 (BITS_PER_EMACS_INT): New constants, replacing
8064 what used to be in config.h, but not useful in #if.
8065 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
8066 define them any more.
8067 (VAL_MAX): New macro.
8069 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
8070 BITS_PER_EMACS_INT, in #if.
8071 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
8072 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
8073 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
8074 * s/ms-w32.h (DATA_START):
8075 Move here from removed file m/intel386.h.
8076 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
8077 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
8079 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
8081 Assume C89 or later.

8091 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
8092 * xterm.c (input_signal_count): Assume volatile works.
8094 2012-05-21 Ken Brown <kbrown@cornell.edu>
8096 * xgselect.c (xg_select): Fix first argument in call to 'select'
8099 2012-05-20 Ken Brown <kbrown@cornell.edu>
8101 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
8102 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
8104 2012-05-19 Ken Brown <kbrown@cornell.edu>
8106 * xfns.c (x_in_use): Remove `static' qualifier.
8107 * xterm.h (x_in_use): Declare.
8108 * xgselect.c: Include xterm.h.
8109 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
8110 and `display_arg' (bug#9754).
8112 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
8114 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
8116 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
8117 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
8119 2012-05-18 Eli Zaretskii <eliz@gnu.org>
8121 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
8123 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
8124 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
8126 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
8127 reference to image_cache->refcount.
8128 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
8130 2012-05-17 Juri Linkov <juri@jurta.org>
8132 * search.c (Fword_search_regexp, Fword_search_backward)
8133 (Fword_search_forward, Fword_search_backward_lax)
8134 (Fword_search_forward_lax): Move functions to isearch.el
8135 (bug#10145, bug#11381).
8137 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
8139 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
8141 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
8143 * lread.c (init_obarray): Declare Qt and Qnil as special.
8145 2012-05-14 Glenn Morris <rgm@gnu.org>
8147 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
8148 Put "libexec" before "bin", for the sake of init_callproc_1.
8150 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
8152 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
8154 * unexaix.c: Port to more-recent AIX compilers.
8155 (report_error, report_error_1, make_hdr, copy_sym)
8156 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
8157 Make arguments const char *, not char *, to avoid violations of C
8158 standard and to fix some AIX warnings reported by Gilles Pion.
8160 2012-05-14 Eli Zaretskii <eliz@gnu.org>
8162 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
8163 already have overlays loaded.
8164 (handle_single_display_spec): Before returning without displaying
8165 fringe bitmap, synchronize the bidi iterator with the main display
8166 iterator, by calling iterate_out_of_display_property.
8167 (iterate_out_of_display_property): Detect buffer iteration by
8168 testing that it->string is a Lisp string.
8169 (get_next_display_element): When the current object is exhausted,
8170 and there's something on it->stack, call set_iterator_to_next to
8171 proceed with what's on the stack, instead of returning zero.
8172 (set_iterator_to_next): If called at the end of a Lisp string,
8173 proceed to consider_string_end without incrementing string
8174 position. Don't increment display vector index past the end of
8175 the display vector. (Bug#11417)
8176 (pos_visible_p): Don't report a position visible when move_it_to
8177 stopped at the last line of window, which happens to be scanned
8178 backwards by the bidi iteration. (Bug#11464)
8180 2012-05-14 Eli Zaretskii <eliz@gnu.org>
8182 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
8183 and right-margin display specs even if the spec is invalid or we
8184 are on a TTY, and thus unable to display on the fringes.
8185 That's because the text with the property will not be displayed anyway,
8186 so we need to signal to the caller that this is a "replacing"
8187 display spec. This fixes display when the spec is invalid or we
8190 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
8192 * unexaix.c (make_hdr): Fix typo in prototype.
8193 This bug broke the build on AIX. Problem reported by Gilles Pion.
8195 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
8197 * keyboard.c (kbd_buffer_get_event): Read special events also in
8198 batch mode. (Bug#11415)
8200 2012-05-12 Glenn Morris <rgm@gnu.org>
8202 * ns.mk: Update for ns_appbindir no longer having trailing "/".
8204 2012-05-12 Eli Zaretskii <eliz@gnu.org>
8206 * lisp.mk (lisp): Add newcomment.elc.
8208 2012-05-12 Glenn Morris <rgm@gnu.org>
8210 * Makefile.in (MKDIR_P): New, set by configure.
8211 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
8213 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
8215 Remove unused function hourglass_started.
8216 * dispextern.h (hourglass_started):
8217 * w32fns.c (hourglass_started):
8218 * xdisp.c (hourglass_started): Remove.
8220 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
8222 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
8223 Update dependencies.
8225 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
8227 * xgselect.c (xg_select): Put maxfds+1 into a var.
8228 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
8230 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
8232 2012-05-10 Dave Abrahams <dave@boostpro.com>
8234 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
8235 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
8237 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
8239 * dbusbind.c (xd_registered_buses): New internal Lisp object.
8240 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
8241 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
8242 Initialize xd_registered_buses.
8244 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
8246 Untag more efficiently if USE_LSB_TAG.
8247 This is based on a proposal by YAMAMOTO Mitsuharu in
8248 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
8249 For an admittedly artificial (nth 8000 longlist) benchmark on
8250 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
8251 Emacs's overall text size by 1%.
8252 * lisp.h (XUNTAG): New macro.
8253 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
8254 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
8255 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
8256 * eval.c (Fautoload):
8257 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
8258 * frame.h (XFRAME): Use XUNTAG.
8260 Port recent dbusbind.c changes to 32-bit --with-wide-int.
8261 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
8262 Remove unportable assumptions about print widths of types like
8264 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
8265 intptr_t when converting between pointer and integer, to avoid GCC
8266 warnings about wrong width.
8268 2012-05-09 Eli Zaretskii <eliz@gnu.org>
8270 * w32proc.c (new_child): Force Windows to reserve only 64KB of
8271 stack for each reader_thread, instead of defaulting to 8MB
8272 determined by the linker. This avoids failures in creating
8273 subprocesses on Windows 7, see the discussion in this thread:
8274 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
8276 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
8278 Fix up display of the *Minibuf-0* buffer in the mini window.
8279 * keyboard.c (read_char): Don't clear the echo area if there's no
8281 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
8282 contents of *Minibuf-0*) if there's no message displayed in its stead.
8284 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
8286 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
8289 2012-05-06 Chong Yidong <cyd@gnu.org>
8291 * lisp.mk (lisp): Update.
8293 2012-05-05 Jim Meyering <meyering@redhat.com>
8295 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
8297 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
8299 * data.c (PUT_ERROR): New macro.
8300 (syms_of_data): Use it. Add new error type `user-error'.
8301 * undo.c (user_error): New function.
8302 (Fprimitive_undo): Use it.
8303 * print.c (print_error_message): Adjust print style for `user-error'.
8304 * keyboard.c (user_error): New function.
8305 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
8307 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
8309 Do not limit current-time-string to years 1000..9999.
8310 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
8311 (Fcurrent_time_string): Support any year that is supported by the
8312 underlying localtime representation. Don't use asctime, as it
8313 has undefined behavior for years outside the range -999..9999.
8315 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
8317 Fix race conditions involving setenv, gmtime, localtime, asctime.
8318 Without this fix, interrupts could mess up code that uses these
8319 nonreentrant functions, since setting TZ invalidates existing
8320 tm_zone or tzname values, and since most of these functions return
8321 pointers to static storage.
8322 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
8323 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
8324 Grow the critical sections to include not just invoking
8325 localtime/gmtime, but also accessing these functions' results
8326 including their tm_zone values if any, and any related TZ setting.
8327 (format_time_string): Last arg is now struct tm *, not struct tm **,
8328 so that the struct tm is saved in the critical section.
8329 All callers changed. Simplify allocation of initial buffer, partly
8330 motivated by the fact that memory allocation needs to be outside
8331 the critical section.
8333 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
8335 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
8336 with RESET_INTERVAL.
8338 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
8339 Remove duplicated buffer name initialization.
8341 2012-05-02 Jim Meyering <jim@meyering.net>
8343 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
8345 * xfns.c (x_window): Use xstrdup (Bug#11375).
8347 2012-05-02 Eli Zaretskii <eliz@gnu.org>
8349 * xdisp.c (pos_visible_p): If already at a newline from the
8350 display string before the 'while' loop, don't walk back the glyphs
8351 from it3.glyph_row. Solves assertion violation when the display
8352 string begins with a newline (egg.el). (Bug#11367)
8354 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
8356 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
8359 2012-05-01 Glenn Morris <rgm@gnu.org>
8361 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
8362 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
8363 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
8364 All were removed before 23.1.
8366 * dispnew.c: Remove HAVE_LIBNCURSES test;
8367 it is always true on relevant platforms.
8369 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
8370 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
8372 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
8374 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
8376 * .gdbinit (xpr): Remove checks for no longer existing misc types.
8377 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
8380 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
8382 Do not avoid creating empty evaporating overlays (Bug#9642).
8383 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
8384 That is, do not delete an evaporating overlay if it becomes
8385 empty after its bounds are adjusted to fit within its buffer.
8386 This fix caused other problems, and I'm reverting it until we get
8387 to the bottom of them.

8391 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
8393 2012-04-27 Eli Zaretskii <eliz@gnu.org>
8395 * xdisp.c (pos_visible_p): If the window start position is beyond
8396 ZV, start the display from buffer beginning. Prevents assertion
8397 violation in init_iterator when the minibuffer window is scrolled
8400 * window.c (window_scroll_pixel_based): Likewise.
8402 2012-04-27 Chong Yidong <cyd@gnu.org>

8420 character. (Bug#11341)
8422 * w32menu.c: Include w32heap.h.
8423 (add_menu_item): If the call to AppendMenuW (via
8424 unicode_append_menu) fails, disable Unicode menus only if we are
8425 running on Windows 9X/Me.
8427 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
8429 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

8450 Do not create empty overlays with the evaporate property (Bug#9642).
8451 * buffer.c (Fmove_overlay): Delete an evaporating overlay
8452 if it becomes empty after its bounds are adjusted to fit within
8453 its buffer. Without this fix, in a nonempty buffer (let ((o
8454 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
8455 yields an empty overlay that has the evaporate property, which is
8456 not supposed to happen.

8596 (print_object): Check for cycles even when print-circle is nil and
8597 print-gensym is t, but only check print_depth if print-circle is nil.
8599 2012-04-20 Chong Yidong <cyd@gnu.org>
8601 * process.c (wait_reading_process_output): If EIO occurs on a pty,
8602 set the status to "failed" and ensure that sentinel is run.

8657 New extern decls, to avoid calling undeclared functions.
8658 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
8659 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
8660 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

8682 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
8684 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

8730 2012-04-11 Daniel Colascione <dancol@dancol.org>
8732 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
8733 against is gone. It's better to use vfork now so that when Cygwin
8734 gains a new, working vfork, we use it automatically (bug#10398).
8736 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

8777 (emacs_gnutls_read): Use new log functions,
8778 `gnutls_handshakes_tried' process member, and

8791 2012-04-09 Eli Zaretskii <eliz@gnu.org>
8793 * xdisp.c (set_cursor_from_row): If the display string appears in
8794 the buffer at position that is closer to point than the position
8795 after the display string, display the cursor on the first glyph of
8796 the display string. Fixes cursor display when a 'display' text
8797 property immediately follows invisible text. (Bug#11094)
8799 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
8801 composite.c: use 'double' consistently
8802 * composite.c (get_composition_id): Use 'double' consistently
8803 instead of converting 'float' to 'double' and vice versa; this is
8804 easier to understand and avoids a GCC warning.
8806 2012-04-09 Glenn Morris <rgm@gnu.org>
8808 * Makefile.in: Generate leim-list with bootstrap-emacs, in
8809 preparation for dumping it with emacs. (Bug#4789)

8840 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
8842 2012-04-07 Eli Zaretskii <eliz@gnu.org>
8844 Support building on MS-Windows with libxml2.
8846 * makefile.w32-in (OBJ2): Add xml.$(O).
8847 (GLOBAL_SOURCES): Add xml.c.
8848 ($(BLD)/xml.$(O)): New dependency list.
8850 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
8851 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
8852 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
8853 [!WINDOWSNT]: New macros.
8854 (init_libxml2_functions, libxml2_loaded_p): New functions.
8855 (parse_region): Call fn_xmlCheckVersion instead of using the macro
8856 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
8857 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
8858 Calls xmlCleanupParser only if libxml2 was loaded (or statically
8860 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
8861 Call init_libxml2_functions before calling libxml2 functions.
8862 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
8864 * emacs.c: Don't include libxml/parser.h.
8865 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
8866 xmlCleanupParser directly.
8868 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
8870 2012-04-07 Eli Zaretskii <eliz@gnu.org>
8872 * indent.c (Fvertical_motion): If there is a display string at
8873 point, use it.vpos to compute how many lines to backtrack after
8874 move_it_to point. (Bug#11133)
8876 2012-04-06 Eli Zaretskii <eliz@gnu.org>
8878 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
8879 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
8880 about subtle differences between FETCH_CHAR* and STRING_CHAR*
8881 macros related to unification of CJK characters. For the details,
8882 see the discussion following the message here:
8883 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
8885 2012-04-04 Chong Yidong <cyd@gnu.org>
8887 * keyboard.c (Vdelayed_warnings_list): Doc fix.
8889 2012-04-01 Eli Zaretskii <eliz@gnu.org>
8891 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
8892 instead of alloca. (Bug#11138)
8894 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
8896 * w32menu.c (is_simple_dialog): Properly check lisp types.
8899 2012-03-31 Eli Zaretskii <eliz@gnu.org>
8901 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
8902 position we get to after a call to move_it_to fails the
8903 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
8904 only if we wind up in a string from display property. (Bug#11063)
8906 * window.c (Fdelete_other_windows_internal): Invalidate the row
8907 and column information about mouse highlight, so that redisplay
8908 restores it after reallocating the glyph matrices. (Bug#7464)
8910 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
8911 string comes from a `display' text property, use the buffer
8912 position of that property as if we actually saw that position in
8914 (move_it_by_lines): Remove the assertion that
8915 "it->current_x == 0 && it->hpos == 0" which can be legitimately
8916 violated when there's a before-string at the beginning of a line.
8919 2012-03-30 Eli Zaretskii <eliz@gnu.org>
8921 * xdisp.c (append_space_for_newline): If the default face was
8922 remapped, use the remapped face for the appended newline.
8923 (extend_face_to_end_of_line): Use the remapped default face for
8924 extending the face to the end of the line.
8925 (display_line): Call extend_face_to_end_of_line when the default
8926 face was remapped. (Bug#11068)
8928 2012-03-29 Eli Zaretskii <eliz@gnu.org>
8930 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
8932 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
8934 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
8936 2012-03-27 Glenn Morris <rgm@gnu.org>
8938 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
8941 2012-03-26 Kenichi Handa <handa@m17n.org>
8943 * dispextern.h (struct glyph): Fix previous change. Change the
8944 bit length of glyphless.ch to 25 (Bug#11082).
8946 2012-03-26 Chong Yidong <cyd@gnu.org>
8948 * keyboard.c (Vselection_inhibit_update_commands): New variable.
8949 (command_loop_1): Use it; inhibit selection update for
8950 handle-select-window too (Bug#8996).
8952 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
8954 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
8956 2012-03-25 Kenichi Handa <handa@m17n.org>
8958 * dispextern.h (struct glyph): Change the bit length of
8959 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
8961 2012-03-24 Eli Zaretskii <eliz@gnu.org>
8963 * s/ms-w32.h (tzname): Include time.h before redirecting to
8964 _tzname. Fixes the MSVC build. (Bug#9960)
8966 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
8968 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
8971 * xterm.c (XTread_socket): Only modify handling_signal if
8972 !SYNC_INPUT. (Bug#11080)
8974 2012-03-23 Eli Zaretskii <eliz@gnu.org>
8976 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
8977 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
8978 when fetching a multibyte character consumes more bytes than
8979 CHAR_BYTES returns, due to unification of CJK characters in
8980 string_char. (Bug#11073)
8982 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
8984 * process.c (wait_reading_process_output): Handle pty disconnect
8985 by refraining from sending oneself a SIGCHLD (bug#10933).
8987 2012-03-22 Chong Yidong <cyd@gnu.org>
8989 * dispextern.h (struct it): New member string_from_prefix_prop_p.
8991 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
8992 Mark string as coming from a prefix property.
8993 (handle_face_prop): Use default face for prefix strings (Bug#4281).
8994 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
8996 2012-03-21 Chong Yidong <cyd@gnu.org>
8998 * xfaces.c (Vface_remapping_alist): Doc fix.
9000 2012-03-20 Eli Zaretskii <eliz@gnu.org>
9002 * w32proc.c (Fw32_set_console_codepage)
9003 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
9006 2012-03-20 Chong Yidong <cyd@gnu.org>
9008 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
9009 to reflect default non-nil value of redisplay-dont-pause.
9011 2012-03-19 Kenichi Handa <handa@m17n.org>
9013 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
9014 it fit in a valid range (Bug#11003).
9016 2012-03-18 Eli Zaretskii <eliz@gnu.org>
9018 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
9019 that is not from display property, accept the row as a "cursor
9020 row" if one of the string's character has a non-nil `cursor'
9021 property. Fixes cursor positioning when there are newlines in
9022 overlay strings, e.g. in icomplete.el. (Bug#11035)
9024 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
9026 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
9028 2012-03-12 Chong Yidong <cyd@gnu.org>
9030 * eval.c (inhibit_lisp_code): Rename from
9031 inhibit_window_configuration_change_hook; move from window.c.
9033 * xfns.c (unwind_create_frame_1, Fx_create_frame):
9034 * window.c (run_window_configuration_change_hook)
9035 (syms_of_window): Callers changed.

9050 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
9052 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
9054 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
9055 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
9058 2012-03-03 Glenn Morris <rgm@gnu.org>
9060 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
9062 2012-03-02 Eli Zaretskii <eliz@gnu.org>
9064 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
9065 position past the first glyph_row that ends at ZV. (Bug#10902)
9066 (redisplay_window, next_element_from_string): Fix typos in
9068 (redisplay_window): Pass to move_it_vertically the margin in
9069 pixels, not in screen lines.
9071 2012-03-02 Glenn Morris <rgm@gnu.org>
9073 * buffer.c (buffer-list-update-hook): Doc fix.
9075 2012-02-29 Eli Zaretskii <eliz@gnu.org>
9077 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
9078 push_it before setting up the iterator for the first overlay
9079 string, even if we have an empty string loaded.
9080 (next_overlay_string): If there's an empty string on the iterator
9081 stack, pop the stack. (Bug#10903)
9083 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
9085 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
9086 Suggested by Stefan Monnier in
9087 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
9088 * alloc.c (widen_to_Lisp_Object): New static function.
9089 (mark_memory): Also mark Lisp_Objects by fetching pointer words
9090 and widening them to Lisp_Objects. This would work even if
9091 USE_LSB_TAG is defined and wide integers are used, which might
9092 happen in a future version of Emacs.
9094 2012-02-25 Chong Yidong <cyd@gnu.org>
9096 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
9099 * xselect.c (Fx_selection_exists_p): Doc fix.
9100 (x_clipboard_manager_save_all): Print an informative message
9101 before saving to clipboard manager.
9103 2012-02-24 Chong Yidong <cyd@gnu.org>
9105 * keyboard.c (process_special_events): Handle all X selection
9106 requests in kbd_buffer, not just the next one (Bug#8869).
9108 2012-02-23 Chong Yidong <cyd@gnu.org>
9110 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
9111 call when setting menu-bar-lines and tool-bar-lines parameters.
9112 (unwind_create_frame_1): New helper function.
9114 * window.c (inhibit_window_configuration_change_hook): New var.
9115 (run_window_configuration_change_hook): Obey it.
9116 (syms_of_window): Initialize it.
9118 2012-02-22 Chong Yidong <cyd@gnu.org>
9120 * xterm.c (x_draw_image_relief): Add missing type check for
9121 Vtool_bar_button_margin (Bug#10743).
9123 2012-02-21 Chong Yidong <cyd@gnu.org>
9125 * fileio.c (Vfile_name_handler_alist): Doc fix.
9127 * buffer.c (Fget_file_buffer): Protect against invalid file
9128 handler return value.
9130 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
9132 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
9133 when computing $valmask.
9135 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
9136 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
9137 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
9138 It's useless in that case, and it can cause problems on hosts
9139 that allocate halves of EMACS_INT values separately.
9140 Reported by Dan Horák. Diagnosed by Andreas Schwab in
9141 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
9142 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
9143 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
9144 it avoids undefined behavior on hosts where shifting right by more
9145 than the word width has undefined behavior.
9147 2012-02-19 Chong Yidong <cyd@gnu.org>
9149 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
9150 (Funhandled_file_name_directory, Ffile_name_as_directory)
9151 (Fdirectory_file_name, Fexpand_file_name)
9152 (Fsubstitute_in_file_name): Protect against invalid file handler
9153 return values (Bug#10845).
9155 2012-02-18 Eli Zaretskii <eliz@gnu.org>
9157 * .gdbinit (pitx): Fix incorrect references to fields of the
9160 2012-02-17 Chong Yidong <cyd@gnu.org>
9162 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
9164 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
9166 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
9167 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
9169 2012-02-15 Chong Yidong <cyd@gnu.org>
9171 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
9172 marked as special. Also, starting docstrings with * is obsolete.
9174 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
9176 * gnutls.c (emacs_gnutls_write): Fix last change.
9178 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

9183 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
9185 * keymap.c (Fsingle_key_description): Handle char ranges.
9187 2012-02-12 Chong Yidong <cyd@gnu.org>
9189 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
9190 as that creates a dangerous corner case.
9192 * window.c (Fdelete_window_internal): Invalidate the mouse
9193 highlight (Bug#9904).
9195 2012-02-12 Glenn Morris <rgm@gnu.org>
9197 * xselect.c (Fx_own_selection_internal)
9198 (Fx_get_selection_internal, Fx_disown_selection_internal)
9199 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
9200 * nsselect.m (Fx_own_selection_internal)
9201 (Fx_disown_selection_internal, Fx_selection_exists_p)
9202 (Fx_selection_owner_p, Fx_get_selection_internal):
9203 Sync docs and argument specs with the xselect.c versions.
9205 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
9207 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
9209 2012-02-11 Eli Zaretskii <eliz@gnu.org>

9225 2012-02-07 Chong Yidong <cyd@gnu.org>
9227 * buffer.c (Fbuffer_local_variables)
9228 (buffer_lisp_local_variables): Handle unbound vars correctly;
9229 don't let Qunbound leak into Lisp.
9231 2012-02-07 Glenn Morris <rgm@gnu.org>
9233 * image.c (Fimagemagick_types): Doc fix.
9235 * image.c (imagemagick-render-type): Change it from a lisp object
9236 to an integer. Move the doc here from the lisp manual.

9239 2012-02-06 Chong Yidong <cyd@gnu.org>
9241 * doc.c (store_function_docstring): Avoid applying docstring of
9242 alias to base function (Bug#2603).
9244 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
9246 * .gdbinit (pp1, pv1): Remove redundant defines.
9249 2012-02-04 Chong Yidong <cyd@gnu.org>
9251 * nsterm.m: Declare a global (Bug#10694).
9253 2012-02-04 Eli Zaretskii <eliz@gnu.org>
9255 * w32.c (get_emacs_configuration_options):
9256 Include --enable-checking, if specified, in the return value.
9258 2012-02-04 Martin Rudalics <rudalics@gmx.at>
9260 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
9261 after rounding frame sizes. (Bug#9723)
9263 2012-02-04 Eli Zaretskii <eliz@gnu.org>
9265 * keyboard.c (adjust_point_for_property): Don't position point
9266 before BEGV. (Bug#10696)
9268 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
9270 Handle overflow when computing char display width (Bug#9496).
9271 * character.c (char_width): Return EMACS_INT, not int.
9272 (char_width, c_string_width): Check for overflow when
9273 computing the width; this is possible now that individual
9274 characters can have unbounded width. Problem introduced
9275 by merge from Emacs 23 on 2012-01-19.
9277 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
9279 * dbusbind.c (Fdbus_register_method): Mention the return value

9292 2012-02-02 Kenichi Handa <handa@m17n.org>
9294 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
9295 0, do not call append_composite_glyph.
9297 2012-02-02 Kenichi Handa <handa@m17n.org>
9299 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
9301 (x_produce_glyphs): If the component of a composition is a null
9302 string, set it->pixel_width to 1 to avoid zero-width glyph.
9304 2012-02-01 Eli Zaretskii <eliz@gnu.org>
9306 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
9307 first 2 arguments are identical. This makes inserting large
9308 output from a subprocess an order of magnitude faster on
9309 MS-Windows, where all sbrk'ed memory is always contiguous.
9311 2012-01-31 Glenn Morris <rgm@gnu.org>

9325 2012-01-28 Chong Yidong <cyd@gnu.org>
9327 * minibuf.c (syms_of_minibuf): Doc fix (Bug#10550).
9329 2012-01-26 Chong Yidong <cyd@gnu.org>

9839 * xdisp.c (redisplay_window): If cursor row is not fully visible
9840 after recentering, and scroll-conservatively is set to a large
9841 number, scroll window by a few more lines to make the cursor fully
9842 visible and out of scroll-margin. (Bug#10105)
9843 (start_display): Don't move to the next line if the display should
9844 start at a newline that is part of a display vector or an overlay

9928 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
9929 is set, removing the need for VIRT_ADDRESS_VARIES.
9930 (PURE_P): Use a more-efficient implementation that needs just one
9931 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
9932 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
9933 to 4 (xorl, subq, cmpq, setbe).
9934 * alloc.c (pure): Always extern now, since that's the
9935 VIRT_ADDR_VARIES behavior.
9936 (PURE_POINTER_P): Use a single comparison, not two, for
9937 consistency with the new puresize.h.
9938 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
9939 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

9946 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
9947 behave as if the cursor position were at the window margin.
9949 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
9950 and the cursor position is out of bounds, behave as if the cursor
9951 position were at the window margin. (Bug#10075)
9953 2011-11-18 Chong Yidong <cyd@gnu.org>
9955 * window.c (Fwindow_combination_limit): Make first argument

9981 * dispnew.c (verify_row_hash): Call row_hash for computing the
9982 hash code of a row, instead of duplicating code from xdisp.c.
9984 * dispextern.h (row_hash): Add prototype.
9986 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

10015 (Fset_window_configuration, save_window_save): Rename all
10016 occurrences of window_nest to window_combination_limit.

10020 * image.c (imagemagick_load_image): Fix typo.
10022 2011-11-14 Eli Zaretskii <eliz@gnu.org>
10024 * xdisp.c (display_line): Move the call to
10025 highlight_trailing_whitespace before the call to
10026 compute_line_metrics, since the latter needs to see the final
10027 faces of all the glyphs to compute ROW's hash value.
10028 Fixes assertion violations in row_equal_p. (Bug#10035)
10030 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
10032 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

10091 Avoid some portability problems by eschewing 'extern inline' functions.
10092 The trivial performance wins aren't worth the portability hassles; see

10101 making these static again.
10102 (offset_intervals, temp_set_point_both, temp_set_point)
10103 (copy_intervals_to_string): No longer inline.
10104 * xdisp.c (window_text_bottom_y, window_box_width)

10161 * xmenu.c (cleanup_widget_value_tree): New function.
10162 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

10169 (window_box_width, window_box_left, window_box_left_offset)
10170 (window_box_right, window_box_right_offset): Declare extern.
10171 Otherwise, these inline functions do not conform to C99 and
10172 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
10173 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
10174 * intervals.c (adjust_intervals_for_insertion)

10177 (static_offset_intervals): Remove.
10178 (offset_intervals): Rewrite using the old contents of
10179 static_offset_intervals. The old version didn't conform to C99

10234 (unwind_create_frame): New function (Bug#9943).
10235 (Fx_create_frame): Restructure code to be more similar to the one in
10236 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).

10288 previous/next-single-property-change returns nil, treat that as
10289 the beginning or the end of the buffer. (Bug#9955)
10291 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
10293 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
10294 label is not null (Bug#9951).
10295 (xg_tool_item_stale_p): Handle the fact that wimage and/or wlbl
10298 2011-11-04 Eli Zaretskii <eliz@gnu.org>
10300 * window.c (Fwindow_body_size): Mention in the doc string that the
10301 return value is in frame's canonical units. (Bug#9949)
10303 2011-11-03 Eli Zaretskii <eliz@gnu.org>
10305 * xdisp.c (note_mouse_highlight): Initialize `area'. (Bug#9947)
10307 * w32fns.c (unwind_create_frame): If needed, free the glyph
10308 matrices of the partially constructed frame. (Bug#9943)
10309 * xfns.c (unwind_create_frame): Likewise.
10311 2011-11-01 Eli Zaretskii <eliz@gnu.org>
10313 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
10314 Don't stop backward scan on the continuation glyph, even though
10315 its CHARPOS is positive.
10316 (mouse_face_from_buffer_pos, note_mouse_highlight):
10317 Rename cover_string to disp_string.
10319 2011-11-01 Martin Rudalics <rudalics@gmx.at>
10321 * window.c (temp_output_buffer_show): Don't use
10322 Vtemp_buffer_show_specifiers.
10323 (Vtemp_buffer_show_specifiers): Remove unused variable.
10325 2011-10-30 Eli Zaretskii <eliz@gnu.org>
10327 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
10328 past the beginning of the current glyph matrix.
10330 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
10332 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
10333 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
10334 HAVE_GTK3 (Bug#9869).
10336 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
10337 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
10339 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
10341 * xterm.c: Declare x_handle_net_wm_state to return int.
10342 (handle_one_xevent): Check if we are iconified but don't have
10343 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
10344 (get_current_wm_state): Return non-zero if not hidden,
10345 check for _NET_WM_STATE_HIDDEN (Bug#9893).

10350 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
10352 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
10353 so that this new function doesn't get optimized away by a
10354 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
10356 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
10358 * frame.h (MOUSE_HL_INFO): Remove excess parens.
10360 2011-10-29 Eli Zaretskii <eliz@gnu.org>
10362 Fix the `xbytecode' command.
10363 * .gdbinit (xprintbytestr): New command.
10364 (xwhichsymbols): Rename from `which'; all callers changed.
10365 (xbytecode): Print the byte-code string as well.
10367 2011-10-29 Kim Storm <storm@cua.dk>
10369 * alloc.c (which_symbols): New function.
10371 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
10373 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
10376 2011-10-29 Glenn Morris <rgm@gnu.org>
10378 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
10379 Not clear what it was for, and it causes various bugs. (Bug#9839)
10381 2011-10-28 Eli Zaretskii <eliz@gnu.org>
10383 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
10384 possible random value that matches one of those tested as
10385 condition to clear the mouse face.
10387 2011-10-28 Chong Yidong <cyd@gnu.org>
10389 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
10391 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
10393 * window.c (make_window): Initialize phys_cursor_on_p.
10395 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
10397 * lisp.h (struct Lisp_Symbol): Update comments.
10399 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
10401 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
10403 2011-10-28 Eli Zaretskii <eliz@gnu.org>
10405 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
10406 <oslsachem@gmail.com> for helping to debug this.
10408 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
10409 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
10410 (g_b_init_get_glyph_outline_w): New static variables.
10411 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
10412 (GetGlyphOutlineW_Proc): New typedefs.
10413 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
10414 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
10416 (w32font_open_internal, compute_metrics):
10417 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
10418 instead of calling the "wide" APIs directly.
10420 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
10422 * w32.h (syms_of_w32font): Add prototype.
10424 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
10426 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
10427 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
10428 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
10429 (Fmove_to_window_line): Doc fix.
10431 2011-10-27 Chong Yidong <cyd@gnu.org>
10433 * process.c (make_process): Set gnutls_state to NULL.
10435 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
10436 non-NULL, regardless of GNUTLS_INITSTAGE.
10437 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
10438 an error. Set process slots as soon as we allocate them.
10440 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
10442 2011-10-27 Chong Yidong <cyd@gnu.org>
10444 * gnutls.c (emacs_gnutls_deinit): New function.
10445 Deallocate credentials structures as well as calling gnutls_deinit.
10446 (Fgnutls_deinit, Fgnutls_boot): Use it.
10448 * process.c (make_process): Initialize GnuTLS credentials to NULL.
10449 (deactivate_process): Call emacs_gnutls_deinit.
10451 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
10453 * image.c (x_create_x_image_and_pixmap):
10454 * w32.c (sys_rename, w32_delayed_load):
10455 * w32font.c (fill_in_logfont):
10456 * w32reg.c (x_get_string_resource): Silence compiler warnings.
10458 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
10460 * w32fns.c (w32_default_color_map): New function,
10461 extracted from Fw32_default_color_map.
10462 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
10464 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
10466 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
10468 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
10470 * keyboard.c (test_undefined): New function (bug#9751).
10471 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
10473 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
10475 * sysdep.c (init_sys_modes): Fix the check for the controlling
10476 terminal (Bug#6649).
10478 2011-10-20 Eli Zaretskii <eliz@gnu.org>
10480 * dispextern.h (struct bidi_it): New member next_en_type.
10482 * bidi.c (bidi_line_init): Initialize the next_en_type member.
10483 (bidi_resolve_explicit_1): When next_en_pos is valid for the
10484 current character, check also for next_en_type being WEAK_EN.
10485 (bidi_resolve_weak): Don't enter the expensive loop if the current
10486 position is before next_en_pos. Record the bidi type of the first
10487 non-ET, non-BN character we find, in addition to its position.
10488 (bidi_level_of_next_char): Invalidate next_en_type when
10489 next_en_pos is over-stepped.
10491 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
10493 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
10494 * editfns.c: Rewrite current-time-zone so that it invokes
10495 the equivalent of (format-time-string "%Z") to get the time zone name.
10496 This fixes a bug when the time zone name contains characters that
10497 need converting from the system time locale to Emacs internal format.
10498 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
10499 that patch fixed format-time-string to do the conversion, but
10500 I forgot to fix current-time-zone.
10501 (format_time_string): New function, containing most of
10502 what Fformat_time_string used to contain.
10503 (Fformat_time_string): Rewrite in terms of format_time_string.
10504 This doesn't change this function's behavior.
10505 (current-time-zone): Rewrite to use format_time_string.
10506 This fixes the bug reported by Michael Schierl in
10507 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
10508 Jason Rumney's 2007-06-07 change worked around this bug, but
10510 * systime.h (tzname, timezone): Remove no-longer-used declarations.
10512 2011-10-19 Eli Zaretskii <eliz@gnu.org>
10514 * xdisp.c (start_display): If the character at POS is displayed
10515 via a display vector, reset IT->current.dpvec_index to zero.
10516 (try_window_reusing_current_matrix): If a line ends in a display
10517 vector or the next line starts in a display vector, continue
10518 redrawing the window even though the character position of
10519 start_row was reached.
10522 2011-10-18 Chong Yidong <cyd@gnu.org>
10524 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
10525 with nobreak-char-display too.
10527 2011-10-18 Eli Zaretskii <eliz@gnu.org>
10529 Fix part 3 of bug#9771.
10530 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
10531 (bidi_resolve_neutral): Don't enter the expensive loop looking for
10532 non-neutral characters if the current character is a paragraph
10533 separator (a.k.a. Newline). This avoids running the same
10534 expensive loop twice, once when we consume the preceding newline
10535 and the other time when the line actually needs to be displayed.
10536 Avoid the loop when we see neutrals on the base embedding level
10537 following a character whose directionality is the same as the
10538 paragraph's. This avoids running the expensive loop when a line
10539 ends in a long sequence of neutrals, like control characters.
10540 Add assertion against STRONG_AL type. Slightly rearrange code
10541 that determines the type of a neutral given the first non-neutral
10543 (bidi_level_of_next_char): Set next_en_pos to zero when
10544 invalidating its info.
10546 2011-10-17 Eli Zaretskii <eliz@gnu.org>
10548 * xdisp.c (push_display_prop): Determine whether to record string
10549 or buffer position by IT->string, not by IT->method. Allow
10550 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
10551 (move_it_vertically_backward): Don't look for character position
10552 immediately after the newline when in a continuation line.
10555 2011-10-15 Martin Rudalics <rudalics@gmx.at>
10557 * window.c (coordinates_in_window): Rewrite and delabelize
10558 vertical border check. (Bug#5357) (Bug#9618)
10560 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
10562 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
10563 errors in XSetWindowBorder (bug#9310).
10565 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
10567 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
10568 avoid crash when xmalloc overrun checking is enabled.
10570 2011-10-13 Eli Zaretskii <eliz@gnu.org>
10572 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
10573 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
10574 cursor motion with <left> and <right> arrow keys.
10576 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
10577 some callers set that themselves.
10579 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10581 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
10582 display string and the previous row comes from the same string and
10583 is empty. (Bug#9739) (Bug#9738)
10585 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
10587 * doc.c (get_doc_string): Encode file name (bug#9735).
10589 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10591 * bidi.c (bidi_level_of_next_char):
10592 * xdisp.c (get_visually_first_element): Remove old incorrect
10593 comments regarding the Unicode Line Separator character.
10595 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
10597 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
10599 * alloc.c (Fgc_status): Do not access beyond zombies array
10600 boundary if nzombies > MAX_ZOMBIES.
10601 * alloc.c (dump_zombies): Add missing format specifier.
10603 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
10605 * xdisp.c (set_cursor_from_row): Simplify conditionals,
10606 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
10608 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
10609 Some packages use them to denote characters with modifiers.
10611 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
10613 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
10614 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
10615 matching a pp-number. Rename parameter var to var1.
10617 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
10619 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
10621 2011-10-08 Glenn Morris <rgm@gnu.org>
10623 * callint.c (Fcall_interactively): Give a more explicit error for the
10624 'c' case with a non-character input. (Bug#8479)
10626 2011-10-08 Eli Zaretskii <eliz@gnu.org>
10628 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
10630 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
10631 lines that are hscrolled on the left.
10633 * dispnew.c (buffer_posn_from_coords): Account for a possible
10634 presence of header-line. (Bug#4426)
10636 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
10638 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
10639 Don't advertise functionality which we discourage or doesn't work.
10641 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
10643 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
10644 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
10645 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
10646 this makes Emacs dump core during garbage collection on rare
10647 occasions. sizeof is obviously inferior to offsetof here, so
10648 stick with offsetof.
10649 (GC_POINTER_ALIGNMENT): New macro.
10650 (mark_memory): Omit 3rd (offset) arg; caller changed.
10651 Don't assume EMACS_INT alignment is the same as pointer alignment.
10653 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
10655 * keyboard.c (read_key_sequence_remapped): New var.
10656 (read_key_sequence): Compute remapping in the right buffer.
10657 (command_loop_1): Use read_key_sequence's remapping directly.
10659 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
10661 * dired.c (file_name_completion): Don't expand file name.
10662 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
10663 before checking file name handler.
10665 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
10666 they've been requested explicitly (bug#9591).
10668 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
10670 * keymap.c (Fsingle_key_description): Use make_specified_string
10671 instead of build_string to build string from push_key_description.
10674 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10676 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
10677 This fixes a Y2038 bug on 64-bit hosts.
10678 * buffer.c (reset_buffer):
10679 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
10680 (Fclear_buffer_auto_save_failure):
10681 Use 0, not -1, to represent an unset failure time, since time_t
10682 might not be signed.
10684 Remove dependency on glibc malloc internals.
10685 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10686 Move back here from lisp.h, but with their new implementations.
10687 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10688 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
10689 * charset.c (charset_table_init): New static var.
10690 (syms_of_charset): Use it instead of xmalloc. This removes a
10691 dependency on glibc malloc internals. See Eli Zaretskii's comment in
10692 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
10693 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10694 Move back to alloc.c.
10695 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10696 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
10698 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
10700 * nsterm.m (windowDidResize): Call x_set_window_size only when
10701 ns_in_resize is true. Otherwise set pixelwidth/height and
10702 call change_frame_size (Bug#9628).
10704 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10706 Port --enable-checking=all to Fedora 14 x86-64.
10707 * charset.c (syms_of_charset): Also account for glibc malloc's
10708 internal overhead when calculating the initial malloc maximum.
10710 Port --enable-checking=all to Fedora 14 x86.
10711 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10713 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
10714 (overrun_check_realloc, overrun_check_free):
10715 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
10716 That way, xmalloc returns a properly-aligned pointer even if
10717 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
10718 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
10719 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
10720 into account when calculating the initial malloc maximum.
10721 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10722 Move here from alloc.c, so that charset.c can use it too.
10723 Properly align; the old code wasn't right for common 32-bit hosts
10724 when configured with --enable-checking=all.
10725 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10726 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
10728 2011-09-29 Eli Zaretskii <eliz@gnu.org>
10730 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
10733 2011-09-28 Eli Zaretskii <eliz@gnu.org>
10735 * xdisp.c (compute_display_string_end): If there's no display
10736 string at CHARPOS, return -1.
10738 * bidi.c (bidi_fetch_char): When compute_display_string_end
10739 returns a negative value, treat the character as a normal
10740 character not covered by a display string. (Bug#9624)
10742 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
10744 * lread.c (Fread_from_string): Fix typo in docstring.
10746 2011-09-27 Eli Zaretskii <eliz@gnu.org>
10748 * xdisp.c (handle_invisible_prop): If invisible text ends on a
10749 newline, reseat the iterator instead of bidi-iterating there one
10750 character at a time. (Bug#9610)
10751 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
10752 TO_CHARPOS if the bidi iterator is at base embedding level.
10754 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
10756 * lread.c (readevalloop): Use correct code for NBSP.
10757 (read1): Likewise. (Bug#9608)
10759 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
10761 * dbusbind.c (Fdbus_register_signal): When service is not
10762 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
10764 2011-09-25 Glenn Morris <rgm@gnu.org>
10766 * buffer.c (truncate-lines): Doc fix.
10768 2011-09-24 Chong Yidong <cyd@stupidchicken.com>

10783 2011-09-24 Eli Zaretskii <eliz@gnu.org>
10785 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
10786 Default value is now t. Doc fix.
10788 * indent.c (Fvertical_motion): Compute and apply the overshoot
10789 logic when moving up, not only when moving down. Fix the
10790 confusing name and values of the it_overshoot_expected variable;
10791 logic changes accordingly. (Bug#9254) (Bug#9549)
10793 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
10794 CHARPOS is covered by a display string which includes newlines.
10795 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
10796 is covered by a display string with embedded newlines.
10798 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
10800 * dbusbind.c (Fdbus_register_signal): Add match rule to
10801 Vdbus_registered_objects_table. (Bug#9581)
10802 (Fdbus_register_method, Vdbus_registered_objects_table):
10805 2011-09-24 Jim Meyering <meyering@redhat.com>
10807 do not ignore write error for any output size
10808 The previous change was incomplete.
10809 While it makes emacs --batch detect the vast majority of stdout
10810 write failures, errors were still ignored whenever the output size is
10811 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
10812 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
10813 && echo FAIL: ignored write error
10814 FAIL: ignored write error
10815 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
10816 && echo FAIL: ignored write error
10817 FAIL: ignored write error
10818 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
10820 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
10822 * emacs.c (Fkill_emacs): In noninteractive mode exit
10823 non-successfully if a write error occurred on stdout. (Bug#9574)
10825 2011-09-21 Eli Zaretskii <eliz@gnu.org>
10827 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
10830 * dispextern.h (struct it): Update the comment documenting what
10833 2011-09-20 Eli Zaretskii <eliz@gnu.org>
10835 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
10836 a display string, extend search for cursor position to end of row.
10837 (find_row_edges): If the row ends in a newline from a display
10838 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
10839 Handle the case of a display string with multiple newlines.
10840 (Fcurrent_bidi_paragraph_direction): Fix search for previous
10841 non-empty line. Fixes confusing cursor motion with arrow keys at
10842 the beginning of a line that starts with whitespace.
10844 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
10846 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
10849 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
10851 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
10852 boolean (Bug#9154).
10854 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10856 * xdisp.c (display_line): Record maximum and minimum buffer
10857 positions even if no glyphs were produced (e.g., by a zero-width
10858 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
10859 buffer positions that will be removed from the glyph row because
10861 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
10862 column is beyond frame width: don't subtract 1 "pixel" when
10863 computing width of the stretch.
10864 (reseat_at_next_visible_line_start): Undo the change made on
10865 2011-09-17 that saved paragraph information and restored it after
10866 the call to `reseat'. (Bug#9545)
10868 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10870 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
10871 and turn window cursor on if cleared (Bug#9415).
10873 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
10875 * search.c (boyer_moore): Take unibyte characters from pattern
10876 literally. (Bug#9458)
10878 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10880 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.

10886 initialized, to pacify gcc -Wuninitialized.
10888 * fileio.c: Report proper errno when syscall falls.
10889 (Finsert_file_contents): Save and restore errno,
10890 so that report_file_error outputs the correct diagnostic.
10891 (Fwrite_region) [CLASH_DETECTION]: Likewise.
10893 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10895 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
10897 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10899 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
10900 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
10902 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10904 * xdisp.c (reseat_at_next_visible_line_start): Keep information
10905 about the current paragraph and restore it after the call to reseat.
10907 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
10908 (bidi_find_paragraph_start): Search back for paragraph beginning
10909 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
10910 (bidi_move_to_visually_next): Only trigger paragraph-related
10911 computations when the last character is a newline or at EOB, not
10912 just any NEUTRAL_B. (Bug#9470)
10914 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
10915 truncated lines if point is covered by a display string. (Bug#9524)
10917 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
10919 * xselect.c: Relax test for outgoing X longs (Bug#9498).
10920 (cons_to_x_long): New function.
10921 (lisp_data_to_selection_data): Use it. Correct the test for
10922 short-versus-long data; it was negated. Break out of vector
10923 loop, for efficiency, when a long datum is discovered.
10925 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
10927 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
10929 2011-09-16 Eli Zaretskii <eliz@gnu.org>
10931 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
10932 GCC PR/17406) by declaring this function with external scope.
10934 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10936 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
10937 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
10939 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
10941 * editfns.c (Fformat): Correctly handle text properties on "%%".

10950 (fill_composite_glyph_string): Add comments about special meaning
10951 of TAB characters in a composition.
10953 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10955 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
10956 This occurs when processing a multibyte format.
10957 Problem reported by Wolfgang Jenker.
10959 2011-09-15 Johan Bockgård <bojohan@gnu.org>
10961 * xdisp.c (try_cursor_movement): Only check for exact match if
10962 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
10964 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10966 Remove unused external symbols.
10967 * dispextern.h (calc_pixel_width_or_height): Remove decl.
10968 * xdisp.c (calc_pixel_width_or_height): Now static.
10969 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
10970 * indent.c (check_display_width):
10971 * w32term.c: Fix comment to match code.
10972 * xterm.c, xterm.h (x_catching_errors): Remove.
10974 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10976 * xselect.c: Use signed conversions more consistently (Bug#9498).
10977 (selection_data_to_lisp_data): Assume incoming selection data are
10978 signed integers, not unsigned. This is to be consistent with
10979 outgoing selection data, which was modified to use signed integers
10980 in as part of the fix to Bug#9196 in response to Jan D.'s comment
10981 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
10982 expects long, not unsigned long.
10984 2011-09-14 Eli Zaretskii <eliz@gnu.org>
10986 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
10987 computation of loop end. Reported by Johan Bockgård
10990 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
10992 * frame.c (Fother_visible_frames_p): Function deleted.
10994 2011-09-12 Eli Zaretskii <eliz@gnu.org>
10996 * indent.c (compute_motion): Process display vector front to back
10997 rather than the other way around. (Bug#2496)
10999 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
11001 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
11003 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
11005 * minibuf.c (Fread_from_minibuffer): Doc fix.
11007 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11009 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
11010 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
11012 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
11014 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
11015 value for non-existent files.
11017 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11019 * fileio.c (Finsert_file_contents): If the file cannot be opened,
11020 set its "size" to -1. This will set the modtime_size field of
11021 the corresponding buffer to -1, which is what
11022 verify-visited-file-modtime expects for files that do not exist.
11025 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
11027 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
11029 * lisp.h: ... from here. push_key_description is no longer
11030 defined in keyboard.c, so its declaration should not be in
11031 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
11032 logically belongs with push_key_description.
11034 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
11036 * buffer.h: Include <sys/types.h> instead of <time.h>.
11037 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
11038 Problem reported by Herbert J. Skuhra.
11040 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
11042 * xml.c (parse_region): Make the parsing work for
11043 non-comment-starting XML files again (bug#9144).
11045 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
11047 * image.c (gif_load): Fix calculation of bottom and right corner.
11050 2011-09-10 Eli Zaretskii <eliz@gnu.org>
11052 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
11053 redisplay in small windows.
11055 2011-09-09 Eli Zaretskii <eliz@gnu.org>
11057 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
11059 2011-09-08 Martin Rudalics <rudalics@gmx.at>
11061 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
11062 Operate on live windows only.
11064 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
11066 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
11068 2011-09-07 Eli Zaretskii <eliz@gnu.org>
11070 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
11071 only under bidi iteration.
11073 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
11075 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
11077 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11079 isnan: Fix porting problem to Solaris 10 with bundled gcc.
11080 Without this fix, the command to link temacs failed due to an
11081 undefined symbol __builtin_isnan. This is because
11082 /usr/include/iso/math_c99.h #defines isnan(x) to
11083 __builtin_isnan(x), but the bundled gcc, which identifies itself
11084 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
11086 * floatfns.c (isnan): #undef, and then #define to a clone of
11088 (Fisnan): Always define, since it's always available now.
11089 (syms_of_floatfns): Always define isnan at the Lisp level.
11091 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11093 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
11095 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11097 * fileio.c: Fix bugs with large file offsets (Bug#9428).
11098 The previous code assumed that file offsets (off_t values) fit in
11099 EMACS_INT variables, which is not true on typical 32-bit hosts.
11100 The code messed up by falsely reporting buffer overflow in cases
11101 such as (insert-file-contents "big" nil 1 2) into an empty buffer
11102 when "big" contains more than 2**29 bytes, even though this
11103 inserts just one byte and does not overflow the buffer.
11104 (Finsert_file_contents): Store file offsets as off_t
11105 values, not as EMACS_INT values. Check for overflow when
11106 converting between EMACS_INT and off_t. When checking for
11107 buffer overflow or for overlap, take the offsets into account.
11108 Don't use EMACS_INT for small values where int suffices.
11109 When checking for overlap, fix a typo: ZV was used where
11110 ZV_BYTE was intended.
11111 (Fwrite_region): Don't assume off_t fits into 'long'.
11112 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
11114 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
11116 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
11118 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
11120 sprintf-related integer and memory overflow issues (Bug#9412).
11122 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
11123 (esprintf, exprintf, evxprintf): New functions.
11124 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
11125 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
11126 (modify_event_symbol): Do not assume that the length of
11127 name_alist_or_stem is safe to alloca and fits in int.
11128 (Fexecute_extended_command): Likewise for function name and binding.
11129 (Frecursion_depth): Wrap around reliably on integer overflow.
11130 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
11131 since some callers pass EMACS_INT values.
11132 (Fsingle_key_description): Don't crash if symbol name contains more
11133 than MAX_ALLOCA bytes.
11134 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
11135 (get_minibuffer): Arg is now EMACS_INT, not int.
11136 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
11137 (esprintf, exprintf, evxprintf): New decls.
11138 * window.h (command_loop_level, minibuf_level): Reflect API changes.
11140 * dbusbind.c (signature_cat): New function.
11141 (xd_signature, Fdbus_register_signal):
11142 Do not overrun buffer; instead, report string overflow.
11144 * dispnew.c (add_window_display_history): Don't overrun buffer.
11145 Truncate instead; this is OK since it's just a log.
11147 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
11148 even if the time zone offset is outlandishly large.
11149 Don't mishandle offset == INT_MIN.
11151 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
11152 when creating daemon; the previous buffer-overflow check was incorrect.
11154 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
11155 which has the guts of the old verror function.
11157 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
11158 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
11160 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
11161 (font_unparse_xlfd): Don't blindly alloca long strings.
11162 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
11163 fits in int, when using sprintf. Use single snprintf to count
11164 length of string rather than counting it via multiple sprintfs;
11165 that's simpler and more reliable.
11166 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
11167 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
11168 sprintf, in case result does not fit in int.
11170 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
11171 (fontset_from_font): Print it.
11173 * frame.c (tty_frame_count): Now printmax_t, not int.
11174 (make_terminal_frame, set_term_frame_name): Print it.
11175 (x_report_frame_params): In X, window IDs are unsigned long,
11176 not signed long, so print them as unsigned.
11177 (validate_x_resource_name): Check for implausibly long names,
11178 and don't assume name length fits in 'int'.
11179 (x_get_resource_string): Don't blindly alloca invocation name;
11180 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
11183 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
11184 (xg_check_special_colors, xg_set_geometry):
11185 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
11187 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
11188 Use esprintf, not sprintf, in case result does not fit in int.
11190 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11191 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
11192 it as a large positive number.
11193 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
11194 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11196 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
11197 in case result does not fit in int.
11199 * print.c (float_to_string): Detect width overflow more reliably.
11200 (print_object): Make sprintf buffer a bit bigger, to avoid potential
11201 buffer overrun. Don't assume list length fits in 'int'. Treat
11202 print length of 0 as 0, not as infinity; to be consistent with other
11203 uses of print length in this function. Don't overflow print length
11204 index. Don't assume hash table size fits in 'long', or that
11205 vectorlike size fits in 'unsigned long'.
11207 * process.c (make_process): Use printmax_t, not int, to format
11208 process-name gensyms.
11210 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
11212 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
11213 to avoid potential buffer overrun.
11215 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
11216 if X resource line is longer than 512 bytes.
11218 * xfns.c (x_window): Make sprintf buffer a bit bigger
11219 to avoid potential buffer overrun.
11221 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
11223 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
11225 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
11227 Integer overflow fixes for scrolling, etc.
11228 Without these, Emacs silently mishandles large integers sometimes.
11229 For example, "C-u 4294967297 M-x recenter" was treated as if
11230 it were "C-u 1 M-x recenter" on a typical 64-bit host.
11232 * xdisp.c (try_window_id): Check Emacs fixnum range before
11233 converting to 'int'.
11235 * window.c (window_scroll_line_based, Frecenter):
11236 Check that an Emacs fixnum is in range before assigning it to 'int'.
11237 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
11238 values converted from Emacs fixnums.
11239 (Frecenter): Don't wrap around a line count if it is out of 'int'
11240 range; instead, treat it as an extreme value.
11241 (Fset_window_configuration, compare_window_configurations):
11242 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
11244 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
11245 that can exceed INT_MAX. Check that EMACS_INT value is in range
11246 before assigning it to the (possibly-narrower) index.
11247 (match_limit): Don't assume that a fixnum can fit in 'int'.
11249 * print.c (print_object): Use ptrdiff_t, not int, for index that can
11252 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
11253 (Fvertical_motion): Don't wrap around LINES values that don't fit
11254 in 'int'. Instead, treat them as extreme values. This is good
11255 enough for windows, which can't have more than INT_MAX lines anyway.
11257 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
11259 * Require libxml/parser.h to avoid compilation warning.
11261 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
11263 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
11264 since this reportedly can destroy thread storage.
11266 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
11268 * syntax.c (find_defun_start): Update all cache variables if
11269 exiting early (Bug#9401).
11271 2011-08-30 Eli Zaretskii <eliz@gnu.org>
11273 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
11275 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
11276 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
11277 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
11279 * term.c (tty_append_glyph): New function.
11280 (produce_stretch_glyph): Static function and its prototype deleted.
11282 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
11285 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
11287 * image.c (parse_image_spec): Check for nonnegative, not for positive,
11288 when checking :margin (Bug#9390).
11289 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
11290 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
11291 so that the name doesn't mislead. All uses changed.
11293 2011-08-28 Johan Bockgård <bojohan@gnu.org>
11295 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
11298 2011-08-27 Eli Zaretskii <eliz@gnu.org>
11300 * xdisp.c (move_it_to): Don't bail out early when reaching
11301 position beyond to_charpos, if we are scanning backwards.
11302 (move_it_vertically_backward): When DY == 0, make sure we get to
11303 the first character in the line after the newline.
11305 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
11307 * ccl.c: Improve and simplify overflow checking (Bug#9196).
11308 (ccl_driver): Do not generate an out-of-range pointer.
11309 (Fccl_execute_on_string): Remove unnecessary check for
11310 integer overflow, noted by Stefan Monnier in
11311 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
11312 Remove a FIXME that didn't need fixing.
11313 Simplify the newly-introduced buffer reallocation code.
11315 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
11317 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
11319 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
11321 Integer and memory overflow issues (Bug#9196).
11323 * doc.c (get_doc_string): Rework so that
11324 get_doc_string_buffer_size is the actual buffer size, rather than
11325 being 1 less than the actual buffer size; this makes xpalloc more
11328 * image.c (x_allocate_bitmap_record, cache_image):
11329 * xselect.c (Fx_register_dnd_atom):
11330 Simplify previous changes by using xpalloc.
11332 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
11333 since either will do and ptrdiff_t is convenient with xpalloc.
11335 * charset.c (charset_table_size)
11336 (struct charset_sort_data.priority): Now ptrdiff_t.
11337 (charset_compare): Don't overflow if priorities differ greatly.
11338 (Fsort_charsets): Don't assume list length fits in int.
11339 Check for size-calculation overflow when allocating sort data.
11340 (syms_of_charset): Allocate an initial charset table that is
11341 just under 64 KiB, to avoid problems with glibc malloc and mmap.
11343 * cmds.c (internal_self_insert): Check for size-calculation overflow.
11345 * composite.h (struct composition.glyph_len): Now int, not unsigned.
11346 The actual value is always <= INT_MAX, and leaving it unsigned made
11347 overflow checking harder.
11349 * dispextern.h (struct glyph_matrix.rows_allocated)
11350 (struct face_cache.size): Now ptrdiff_t, for convenience in use
11351 with xpalloc. The values are still always <= INT_MAX.
11353 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
11355 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
11356 (SAFE_NALLOCA): New macro.
11358 * region-cache.c (struct boundary.pos, find_cache_boundary)
11359 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
11360 (set_cache_region, invalidate_region_cache)
11361 (revalidate_region_cache, know_region_cache, region_cache_forward)
11362 (region_cache_backward, pp_cache):
11363 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
11364 so that ptrdiff_t * can be passed to xpalloc.
11365 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
11366 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
11367 (pp_cache): Don't assume cache_len fits in int.
11368 * region-cache.h: Adjust extern decls to match.
11370 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
11371 EMACS_INT, since either will do, for xpalloc.
11373 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
11374 (xnmalloc, xnrealloc, xpalloc): New functions.
11376 * bidi.c (bidi_shelve_header_size): New constant.
11377 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
11378 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
11380 * bidi.c (bidi_cache_shrink):
11381 * buffer.c (overlays_at, overlays_in, record_overlay_string)
11383 Don't update size of array until after memory allocation succeeds,
11384 because xmalloc/xrealloc may not return.
11385 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
11386 now that we have proper integer overflow checking.
11387 (record_overlay_string, overlay_strings): Catch overflows when
11388 calculating size of overlay_str_buf.
11390 * callproc.c (Fcall_process): Check for size overflow when
11391 calculating size of args2.
11392 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
11393 Normally we prefer signed values, but sticking with ptrdiff_t would
11394 require adding more-complicated checks.
11396 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
11397 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
11398 Redo buffer-overflow calculations to avoid integer overflow.
11399 Add a FIXME comment where memory seems to be over-allocated.
11401 * character.c (Fstring): Check for size-calculation overflow.
11403 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
11404 unnecessary integer overflow. Check for size overflow.
11405 (encode_coding_object): Don't update size until xmalloc succeeds.
11407 * composite.c (get_composition_id): Check for overflow in glyph
11408 length calculations.
11410 Integer and memory overflow fixes for display code.
11411 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
11412 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
11413 (scrolling_window): Check for overflow in size calculations.
11414 (line_draw_cost, realloc_glyph_pool, add_row_entry):
11415 Don't assume glyph table len fits in int.

11417 (row_table_size): Now ptrdiff_t, not int.
11418 (scrolling_window): Avoid overflow in size calculations.
11419 Don't update size until allocation succeeds.
11420 * fns.c (concat): Check for overflow in size calculations.
11421 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
11422 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

11425 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
11426 (get_doc_string): Check for size calculation overflow.
11427 Don't update size until allocation succeeds.
11428 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
11429 EMACS_INT, where ptrdiff_t will do.
11430 (Fsubstitute_command_keys): Check for string overflow.
11432 * editfns.c (set_time_zone_rule): Don't assume environment length
11434 (message_length): Now ptrdiff_t, not int.
11435 (Fmessage_box): Don't update size until allocation succeeds.
11436 Don't assume message length fits in int.
11437 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
11439 * emacs.c (main): Do not reallocate argv, since there is a null at
11440 the end that can be overwritten, and this way there's no need to
11441 worry about size-calculation overflow.
11442 (sort_args): Check for size-calculation overflow.
11444 * eval.c (init_eval_once, grow_specpdl): Don't update size until
11446 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
11448 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
11449 (x_set_scroll_bar_width, x_figure_window_size):
11450 Check for integer overflow.
11451 (x_set_alpha): Do not assume XINT fits in int.
11453 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
11454 This is for the members text_lines, text_cols, total_lines, total_cols,
11455 where the system imposes an 'int' limit.
11457 * fringe.c (Fdefine_fringe_bitmap):
11458 Don't update size until alloc works.
11460 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
11461 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
11463 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
11464 Check for size-calculation overflow.
11465 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
11466 do, as we prefer signed integers.
11467 (id_to_widget.max_size, id_to_widget.used)
11468 (xg_store_widget_in_map, xg_remove_widget_from_map)
11469 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
11470 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
11471 Use and return ptrdiff_t, not int.
11472 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
11473 * gtkutil.h: Change prototypes to match the above.
11475 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
11476 are duplicate now that they've been promoted to lisp.h.
11477 (x_allocate_bitmap_record, x_alloc_image_color)
11478 (make_image_cache, cache_image, xpm_load):
11479 Don't update size until alloc is done.
11480 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
11482 Check for size calculation overflow.
11483 (ct_colors_allocated_max): New constant.
11484 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
11487 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
11488 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
11489 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
11490 Use ptrdiff_t, not int, to count maps.
11491 (read_char_minibuf_menu_prompt): Check for overflow in size
11492 calculations. Don't update size until allocation succeeds.
11493 Redo calculations to avoid overflow.
11494 * keyboard.h: Change prototypes to match the above.
11496 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
11498 (current_minor_maps): Check for size calculation overflow.
11499 * keymap.h: Change prototypes to match the above.
11501 * lread.c (read1, init_obarray): Don't update size until alloc done.
11503 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
11504 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
11506 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
11507 Now ptrdiff_t, not int.
11508 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

11520 (Fset_match_data): Don't assume list lengths fit in 'int'.
11522 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
11523 for command line length. Do not attempt to address one before the
11524 beginning of an array, as that's not portable.
11526 * term.c (max_frame_lines): Remove; unused.
11527 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
11529 (encode_terminal_code, calculate_costs): Check for size
11530 calculation overflow.

11533 done. Redo calculations to avoid overflow.
11534 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
11536 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
11537 subtracting pointers.
11538 (gobble_line): Check for overflow more carefully. Don't update size
11541 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.

11552 Use ptrdiff_t, not int, for sizes.
11553 (Finternal_make_lisp_face, cache_face):
11554 Check for size calculation overflow.
11555 (cache_face): Treat size calculation overflows as if they were
11556 memory exhaustion (the usual treatment), rather than aborting.
11558 * xfns.c (x_encode_text, x_set_name_internal)
11559 (Fx_change_window_property): Use ptrdiff_t, not int, to count
11560 sizes, since they can exceed INT_MAX in size. Check for size
11561 calculation overflow.
11563 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
11564 (xg_select): Check for size calculation overflow.
11565 Don't update size until alloc done.
11567 * xrdb.c (get_environ_db): Don't assume path length fits in int,
11568 as sprintf is limited to int lengths.
11570 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
11571 (X_LONG_MIN): New macros.
11572 Use them to make the following changes clearer.
11573 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
11574 This change doesn't affect the value now, but it may help remind
11575 future maintainers not to raise the value too much later.
11576 (SELECTION_QUANTUM): Remove, replacing with ...
11577 (selection_quantum): ... new function, which avoids overflow.
11579 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
11580 assumption that selection length fits in 'int'.
11581 (x_reply_selection_request, x_handle_selection_request)
11582 (x_get_window_property, receive_incremental_selection)
11583 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
11584 (lisp_data_to_selection_data, clean_local_selection_data):

11586 (x_reply_selection_request, x_get_window_property)
11587 (receive_incremental_selection, x_property_data_to_lisp):
11588 Redo calculations to avoid overflow.
11589 (x_reply_selection_request): When sending hint, ceiling it at
11590 X_LONG_MAX rather than relying on wraparound overflow to send
11592 (x_get_window_property, receive_incremental_selection)
11593 (lisp_data_to_selection_data, x_property_data_to_lisp):
11594 Check for size-calculation overflow.
11595 (x_get_window_property, receive_incremental_selection)
11596 (lisp_data_to_selection_data, Fx_register_dnd_atom):
11597 Don't store size until memory allocation succeeds.
11598 (x_get_window_property): Plug memory leak on memory exhaustion.
11599 Don't double-block input; malloc is safe here. Don't assume 2**34
11600 - 4 fits in unsigned long. Add an xassert to check
11601 XGetWindowProperty overflow. Be more careful about overflow
11602 calculations, and distinguish size from memory overflow better.
11603 (receive_incremental_selection): When tracing, don't assume
11604 unsigned int is less than INT_MAX.
11605 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
11606 harmful) conversions of unsigned short to int.
11607 (lisp_data_to_selection_data): Don't assume that integers
11608 in the range -65535 through -1 fit in an X unsigned short.
11609 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
11610 result parameters unless successful. Rely on cons_to_unsigned
11611 to report problems with elements; the old code wasn't right anyway.
11612 (x_check_property_data): Check for int overflow; we cannot use
11613 a wider type due to X limits.
11614 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
11616 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
11618 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)

11645 * image.c (xpm_get_color_table_h):
11646 * lisp.h (hash_lookup, hash_put):
11647 * minibuf.c (Ftest_completion):
11648 Use ptrdiff_t for hash table indexes, not int (which is too
11649 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
11650 32-bit --with-wide-int hosts).
11652 * charset.c (Fdefine_charset_internal): Check for integer overflow.
11653 Add a FIXME comment about memory leaks.
11654 (syms_of_charset): Don't assume xmalloc returns.
11656 Don't assume that stated character widths fit in int.
11657 * character.c (Fchar_width, c_string_width, lisp_string_width):
11658 * character.h (CHAR_WIDTH):
11659 * indent.c (MULTIBYTE_BYTES_WIDTH):
11660 Use sanitize_char_width to avoid undefined and/or bad behavior
11661 with outlandish widths.
11662 * character.h (sanitize_tab_width): Rename from sanitize_width,
11663 now that we have two such functions. All uses changed.
11664 (sanitize_char_width): New inline function.

11675 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
11677 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
11678 Remove unreachable code.
11679 (read_hex, load_charset_map_from_file): Check for integer overflow.
11681 * xterm.c: Don't go over XClientMessageEvent limit.
11682 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
11683 (x_send_scroll_bar_event): Likewise. Check that the size does not
11684 exceed limits imposed by XClientMessageEvent, as well as the usual
11685 ptrdiff_t and size_t limits.
11687 * keyboard.c: Overflow, signedness and related fixes.
11688 (make_lispy_movement): Use same integer type in forward decl
11689 that is used in the definition.
11690 (read_key_sequence, keyremap_step):
11691 Change bufsize argument back to int, undoing my 2011-03-30 change.
11692 We prefer signed types, and int is wide enough here.
11693 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
11694 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
11695 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
11696 length, not size_t. Use ptrdiff_t for index, not int.
11697 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
11698 possibility of integer overflow.
11700 Overflow, signedness and related fixes for images.

11721 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
11722 (lookup_image): Remove unnecessary tests.
11723 (xbm_image_p): Locals are now of int, not EMACS_INT,
11724 since parse_image_check makes sure they fit into int.
11725 (png_load, gif_load, svg_load_image):
11726 Prefer int to unsigned where either will do.
11727 (tiff_handler): New function, combining the cores of the
11728 old tiff_error_handler and tiff_warning_handler.
11729 This function is rewritten to use vsnprintf and thereby avoid
11730 stack buffer overflows. It uses only the features of vsnprintf
11731 that are common to both POSIX and native Microsoft.
11732 (tiff_error_handler, tiff_warning_handler): Use it.
11733 (tiff_load, gif_load, imagemagick_load_image):
11734 Don't assume :index value fits in 'int'.
11735 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
11736 (imagemagick_load_image): Check that crop parameters fit into
11737 the integer types that MagickCropImage accepts. Don't assume
11738 Vimagemagick_render_type has a nonnegative value. Don't assume
11739 size_t fits in 'long'.
11740 (gs_load): Use printmax_t to print the widest integers possible.
11741 Check for integer overflow when computing image height and width.

11753 handle_single_display_spec, not just 1 or zero.
11754 (handle_single_display_spec): If the display spec is of the form
11755 `(space ...)', and specifies display in the text area, return 2
11757 (try_cursor_movement): Check for the need to scroll more
11758 accurately, and prefer exact match for point under bidi.
11759 Don't advance `row' beyond the last row of the window.
11761 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
11762 into disp_prop; all users changed.
11764 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
11765 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
11766 for the text covered by the display property.

11776 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
11777 buffers, return left-to-right.
11778 (set_cursor_from_row): Consider candidate row a win if its glyph
11779 represents a newline and point is on that newline. Fixes cursor
11780 positioning on the newline at EOL of R2L text within L2R
11781 paragraph, and vice versa.
11782 (try_cursor_movement): Check continued rows, in addition to
11783 continuation rows. Fixes unwarranted scroll when point enters a
11784 continued line of R2L text within an L2R paragraph, or vice versa.
11785 (cursor_row_p): Consider the case of point being equal to
11786 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
11787 from the end of a short line to the beginning of a continued line
11788 of R2L text within L2R paragraph.
11789 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
11790 composed characters.

11805 2011-08-22 Kenichi Handa <handa@m17n.org>
11807 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
11808 extra slot even if the purpose is char-code-property-table.
11810 2011-08-23 Eli Zaretskii <eliz@gnu.org>
11812 * xdisp.c (redisplay_window): When computing centering_position,
11813 account for the height of the header line. (Bug#8874)
11815 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
11816 instead of CHAR_TO_BYTE. Fixes a crash when a completion
11817 candidate is selected by the mouse, and that candidate has a
11818 composed character under the mouse.
11820 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
11821 coordinates reported by pos-visible-in-window-p for a composed
11822 character in column zero.
11824 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
11826 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
11828 2011-08-22 Eli Zaretskii <eliz@gnu.org>
11830 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
11831 consider it a hit if to_charpos is anywhere in the range of the
11832 composed buffer positions.
11834 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
11836 * image.c (gif_load): Don't assume that each subimage has the same
11837 dimensions as the base image. Handle disposal method that is
11838 "undefined" by the gif spec (Bug#9335).
11840 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
11842 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

11847 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
11848 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
11849 from an Org mode buffer to a Speedbar frame.
11851 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
11852 a composition, take its buffer position from IT->cmp_it.charpos.
11853 Fixes cursor positioning at the beginning of a line that begins
11854 with a composed character.
11856 2011-08-18 Eli Zaretskii <eliz@gnu.org>
11858 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
11859 character bidirectional type, use STRONG_L instead. Fixes crashes
11860 in a buffer produced by `describe-categories'.
11862 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
11863 members before the level stack, so they would be saved and
11864 restored when copying iterator state. Fixes incorrect reordering
11865 around TABs covered by display properties.
11867 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
11869 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

11939 * xdisp.c (move_it_in_display_line_to): Don't invoke
11940 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
11941 ppos_it. Fixes vertical cursor motion when line beginning is
11942 covered by an image. (Bug#9296)
11944 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
11946 * nsterm.h (ns_run_ascript): Declare.

11951 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
11952 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
11953 the event loop. Get status from as_status (Bug#7276).
11955 * nsterm.m (sendEvent): If event is NSApplicationDefined and
11956 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
11957 the event loop (Bug#7276).
11959 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

11982 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
11983 (Fnetwork_interface_list): Allocate in increments of bytes instead
11984 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
11985 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
11987 (struct ifflag_def): notrailers is smart on OSX.
11988 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
11989 Get hardware address with getifaddrs if available.
11991 2011-08-12 Eli Zaretskii <eliz@gnu.org>
11993 * xdisp.c (iterate_out_of_display_property): xassert that
11994 IT->position is set to within IT->object's boundaries. Break from
11995 the loop as soon as EOB is reached; avoids infloops in redisplay

11997 Set IT->current to match the bidi iterator unconditionally.
11998 (push_display_prop): Allow GET_FROM_STRING as IT->method on
11999 entry. Force push_it to save on the stack the current
12000 buffer/string position, to be restored by pop_it. Fix flags in
12001 the iterator structure wrt the object coming from a display
12002 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
12003 properties. (Bug#9284)
12005 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
12007 * fontset.c (fontset_get_font_group): Add proper type checks.

12032 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
12034 * composite.c (autocmp_chars): Don't reset point. That is done by
12035 restore_point_unwind (Bug#5984).
12037 2011-08-07 Juri Linkov <juri@jurta.org>
12039 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
12040 to show the arg `TIME' instead of `TIMEVAL'.
12042 2011-08-06 Eli Zaretskii <eliz@gnu.org>
12044 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
12045 display property strides EOL and includes a newline, as in
12046 longlines-mode. (Bug#9254)
12047 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
12048 word-wrap under bidirectional display. (Bug#9224)
12050 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
12051 is non-zero, even if the data buffer is NULL. Fixes a crash in
12052 vertical-motion with longlines-mode. (Bug#9254)
12054 2011-08-05 Eli Zaretskii <eliz@gnu.org>
12056 * bidi.c <bidi_cache_total_alloc>: Now static.

12059 * xdisp.c (display_line): Release buffer allocated for shelved bidi
12062 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
12063 amount allocated this far in `bidi_cache_total_alloc'.
12064 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
12065 non-zero, only free the data buffer without restoring the cache
12066 contents. All callers changed.
12068 * dispextern.h (bidi_unshelve_cache): Update prototype.
12070 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
12071 (move_it_in_display_line, move_it_to)
12072 (move_it_vertically_backward, move_it_by_lines): Replace the call
12073 to xfree to an equivalent call to bidi_unshelve_cache.
12074 (move_it_in_display_line_to): Fix logic of returning
12075 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
12077 2011-08-05 Eli Zaretskii <eliz@gnu.org>
12079 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
12080 came from a string character with a `cursor' property. (Bug#9229)
12082 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
12084 * Makefile.in (LIB_PTHREAD): New variable.
12085 (LIBES): Add LIB_PTHREAD (Bug#9216).
12087 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:

12092 * regex.c (re_iswctype): Remove some redundant boolean conversions.
12094 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
12096 * xterm.c (x_find_topmost_parent): New function.
12097 (x_set_frame_alpha): Find topmost parent window with
12098 x_find_topmost_parent and set the property there also (bug#9181).
12099 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
12101 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
12103 * callproc.c (Fcall_process): Avoid vfork clobbering
12104 the local vars buffer, coding_systems, current_dir.
12106 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
12108 * keymap.c (Fmake_composed_keymap): Move to subr.el.
12110 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
12112 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
12113 so that it is not optimized away.
12115 * xdisp.c (compute_display_string_pos): Remove unused local.
12117 2011-08-02 Eli Zaretskii <eliz@gnu.org>
12119 Fix slow cursor motion and scrolling in large buffers with
12120 selective display, like Org Mode buffers. (Bug#9218)
12122 * dispextern.h (struct bidi_it): New member disp_prop_p.
12124 * xdisp.c: Remove one-slot cache of display string positions.
12125 (compute_display_string_pos): Accept an additional argument
12126 DISP_PROP_P; callers changed. Scan at most 5K characters forward
12127 for a display string or property. If found, set DISP_PROP_P
12130 * bidi.c (bidi_fetch_char): Accept an additional argument
12131 DISP_PROP_P, and pass it to compute_display_string_pos.
12132 Only handle text covered by a display string if DISP_PROP_P is returned
12133 non-zero. All callers of bidi_fetch_char changed.
12135 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
12137 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
12139 2010-12-03 Don March <don@ohspite.net>
12141 * keymap.c (Fdefine_key): Fix non-prefix key error message when
12142 last character M-[char] is translated to ESC [char] (bug#7541).
12144 2011-08-02 Kenichi Handa <handa@m17n.org>
12146 * lisp.h (uniprop_table): Extern it.
12148 * chartab.c (uniprop_table): Make it non-static.
12150 2011-08-01 Eli Zaretskii <eliz@gnu.org>
12152 * xdisp.c (forward_to_next_line_start): Accept additional argument
12153 BIDI_IT_PREV, and store into it the state of the bidi iterator had
12155 (reseat_at_next_visible_line_start): Use the bidi iterator state
12156 returned by forward_to_next_line_start to restore the state of
12157 it->bidi_it after backing up to previous newline. (Bug#9212)
12159 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
12161 * regex.c (re_comp): Protoize.
12162 (re_exec): Fix return type.
12163 (regexec): Fix type of `ret'. (Bug#9203)
12165 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12167 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
12168 This is needed if max-image-size is a floating-point number.
12170 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
12172 * print.c (print_object): Print empty symbol as ##.
12174 * lread.c (read1): Read ## as empty symbol.
12176 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
12178 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
12179 setting frame foreground color (Bug#9175).
12180 (x_set_background_color): Likewise.
12182 * nsmenu.m (-setText): Size tooltip dimensions precisely to
12183 contents (Bug#9176).
12184 (EmacsTooltip -init): Remove bezels and add shadows to
12187 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
12188 or scroll bar (Bug#8470).
12190 * nsfont.m (nsfont_open): Remove assignment to voffset and
12191 unnecessary vars hshink, expand, hd, full_height, min_height.
12192 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
12194 * nsterm.h (nsfont_info): Remove voffset field.
12196 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
12198 Implement strike-through and overline on NextStep (Bug#8863).
12200 * nsfont.m (nsfont_open): Use underline position provided by font,
12201 instead of hard-coded value of 2.
12202 (nsfont_draw): Call ns_draw_text_decoration instead.
12204 * nsterm.h: Add declaration for ns_draw_text_decoration.
12206 * nsterm.m (ns_draw_text_decoration): New function for drawing
12207 underline, overline, and strike-through.
12208 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
12209 ns_draw_text_decoration. Change treatment of cursor drawing to
12210 accommodate underlining, etc.
12212 2011-07-28 Eli Zaretskii <eliz@gnu.org>
12214 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
12217 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12219 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
12220 Without this fix, if a signal arrives just after memory fills up,
12221 'malloc' might be invoked reentrantly.
12223 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
12224 In other words, assume that every image size is allowed, on non-X
12225 hosts. This assumption is probably wrong, but it lets Emacs compile.
12227 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
12229 * regex.c (re_iswctype): Convert return values to boolean.
12231 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
12233 * xdisp.c (compute_display_string_pos): Don't use cached display
12234 string position if the buffer had its restriction changed.
12237 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12239 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12241 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12243 Integer signedness and overflow and related fixes. (Bug#9079)
12245 * bidi.c: Integer size and overflow fixes.
12246 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
12247 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
12248 (bidi_cache_find_level_change, bidi_cache_ensure_space)
12249 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
12250 (bidi_find_other_level_edge):
12251 Use ptrdiff_t instead of EMACS_INT where either will do.
12252 This works better on 32-bit hosts configured --with-wide-int.
12253 (bidi_cache_ensure_space): Check for size-calculation overflow.
12254 Use % rather than repeated addition, for better worst-case speed.
12255 Don't set bidi_cache_size until after xrealloc returns, because it
12257 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
12258 (bidi_cache_ensure_space): Also check that the bidi cache size
12259 does not exceed that of the largest Lisp string or buffer. See Eli
12260 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
12262 * alloc.c (__malloc_size_t): Remove.
12263 All uses replaced by size_t. See Andreas Schwab's note
12264 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
12266 * image.c: Improve checking for integer overflow.
12267 (check_image_size): Assume that f is nonnull, since
12268 it is always nonnull in practice. This is one less thing to
12269 worry about when checking for integer overflow later.
12270 (x_check_image_size): New function, which checks for integer
12271 overflow issues inside X.
12272 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
12273 This removes the need for a memory_full check.
12274 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
12275 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
12276 (xbm_read_bitmap_data): Change locals back to 'int', since
12277 their values must fit in 'int'.
12278 (xpm_load_image, png_load, tiff_load):
12279 Invoke x_create_x_image_and_pixmap earlier,
12280 to avoid much needless work if the image is too large.
12281 (tiff_load): Treat overly large images as if
12282 x_create_x_image_and_pixmap failed, not as malloc failures.
12283 (gs_load): Use x_check_image_size.
12285 * gtkutil.c: Omit integer casts.
12286 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
12287 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
12289 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
12291 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
12292 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
12293 would wrongly return t on a 64-bit host.
12295 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
12296 The plain *_OVERFLOW macros run afoul of GCC bug 49705
12297 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
12298 and therefore cause GCC to emit a bogus diagnostic in some cases.
12300 * image.c: Integer signedness and overflow and related fixes.
12301 This is not an exhaustive set of fixes, but it's time to
12302 record what I've got.
12303 (lookup_pixel_color, check_image_size): Remove redundant decls.
12304 (check_image_size): Don't assume that arbitrary EMACS_INT values
12305 fit in 'int', or that arbitrary 'double' values fit in 'int'.
12306 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
12307 (tiff_load, imagemagick_load_image):
12308 Check for overflow in size calculations.
12309 (x_create_x_image_and_pixmap): Remove unnecessary test for
12310 xmalloc returning NULL; that can't happen.
12311 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
12312 (xpm_color_bucket): Use better integer hashing function.
12313 (xpm_cache_color): Don't possibly over-allocate memory.
12314 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
12315 (gif_memory_source):
12316 Use ptrdiff_t, not int or size_t, to record sizes.
12317 (png_load): Don't assume values greater than 2**31 fit in 'int'.
12318 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
12319 either works, as we prefer signed integers.
12320 (tiff_read_from_memory, tiff_write_from_memory):
12321 Return tsize_t, not size_t, since that's what the TIFF API wants.
12322 (tiff_read_from_memory): Don't fail simply because the read would
12323 go past EOF; instead, return a short read.
12324 (tiff_load): Omit no-longer-needed casts.
12325 (Fimagemagick_types): Don't assume size fits into 'int'.
12327 Improve hashing quality when configured --with-wide-int.
12328 * fns.c (hash_string): New function, taken from sxhash_string.
12329 Do not discard information about ASCII character case; this
12330 discarding is no longer needed.
12331 (sxhash-string): Use it. Change sig to match it. Caller changed.
12332 * lisp.h: Declare it.
12333 * lread.c (hash_string): Remove, since we now use fns.c's version.
12334 The fns.c version returns a wider integer if --with-wide-int is
12335 specified, so this should help the quality of the hashing a bit.
12337 * emacs.c: Integer overflow minor fix.
12338 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
12339 Define only if GNU_LINUX.
12340 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
12342 * dispnew.c: Integer signedness and overflow fixes.
12343 Remove unnecessary forward decls, that were a maintenance hassle.
12344 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
12346 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
12347 (scrolling_window): Use ptrdiff_t, not int, for byte count.
12348 (prepare_desired_row, line_draw_cost):
12349 Use int, not unsigned, where either works.
12350 (save_current_matrix, restore_current_matrix):
12351 Use ptrdiff_t, not size_t, where either works.
12352 (init_display): Check for overflow more accurately, and without
12353 relying on undefined behavior.
12355 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
12356 Remove, replacing with the new symbols in lisp.h. All uses changed.
12357 * fileio.c (make_temp_name):
12358 * filelock.c (lock_file_1, lock_file):
12359 * xdisp.c (message_dolog):
12360 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
12361 Use pMd etc. instead.
12362 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
12363 replacing the pWIDE etc. symbols removed from editfns.c.
12365 * keyboard.h (num_input_events): Now uintmax_t.
12366 This is (very slightly) less likely to mess up due to wraparound.
12369 * buffer.c: Integer signedness fixes.
12370 (alloc_buffer_text, enlarge_buffer_text):
12371 Use ptrdiff_t rather than size_t when either will do, as we prefer
12374 * alloc.c: Integer signedness and overflow fixes.
12375 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
12376 (__malloc_size_t): Default to size_t, not to int.
12377 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
12378 (Fgarbage_collect, mark_object_loop_halt, mark_object):
12379 Prefer ptrdiff_t to size_t when either would do, as we prefer
12381 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
12382 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
12383 Now const. Initialize with values that are in range even if char
12385 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
12386 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
12387 These functions do the right thing with sizes > 2**32.
12388 (check_depth): Now ptrdiff_t, not int.
12389 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
12390 Adjust to new way of storing sizes. Check for size overflow bugs
12392 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
12393 slightly wrong anyway, as it missed one instance of
12394 XMALLOC_OVERRUN_CHECK_OVERHEAD.
12395 (refill_memory_reserve): Omit needless cast to size_t.
12396 (mark_object_loop_halt): Mark as externally visible.
12398 * xselect.c: Integer signedness and overflow fixes.
12399 (Fx_register_dnd_atom, x_handle_dnd_message):
12400 Use ptrdiff_t, not size_t, since we prefer signed.
12401 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
12402 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
12403 x_dnd_atoms_size and x_dnd_atoms_length.
12405 * doprnt.c: Prefer signed to unsigned when either works.
12407 * doprnt.c (doprnt):
12409 * xdisp.c (vmessage):
12410 Use ptrdiff_t, not size_t, when using or implementing doprnt,
12411 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
12412 prefer signed arithmetic to avoid comparison confusion.
12413 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
12414 but is a bit tricky.
12416 Assume freestanding C89 headers, string.h, stdlib.h.
12417 * data.c, doprnt.c, floatfns.c, print.c:
12418 Include float.h unconditionally.
12419 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
12420 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
12421 * regex.c: Likewise for stddef.h, string.h.
12422 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
12423 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
12424 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
12425 (STDC_HEADERS): Remove obsolete defines.
12426 * sysdep.c: Include limits.h unconditionally.
12428 Assume support for memcmp, memcpy, memmove, memset.
12429 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
12430 * regex.c (memcmp, memcpy):
12431 Remove; we assume C89 now.
12433 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
12434 (__malloc_safe_bcopy): Remove; no longer needed.
12436 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
12437 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
12438 well either way, and we prefer signed to unsigned.
12440 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
12442 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
12443 closes the connection while we're reading (bug#9182).
12445 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
12447 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
12448 are specified (Bug#9168).
12450 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
12452 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
12453 Found by GCC static checking and --with-wide-int on a 32-bit host.
12455 2011-07-25 Eli Zaretskii <eliz@gnu.org>
12457 * xdisp.c (compute_display_string_pos): Fix logic of caching
12458 previous display string position. Initialize cached_prev_pos to
12459 -1. Fixes slow-down at the beginning of a buffer.
12461 2011-07-24 Eli Zaretskii <eliz@gnu.org>
12463 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
12464 for attrs[LFACE_FONTSET_INDEX].
12466 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
12468 * xml.c (parse_region): Remove unused local
12469 that was recently introduced.
12471 2011-07-23 Eli Zaretskii <eliz@gnu.org>
12473 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
12474 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
12476 * xdisp.c (move_it_in_display_line_to): Record the best matching
12477 position for TO_CHARPOS while scanning the line, and restore it on
12478 exit if none of the characters scanned was an exact match.
12479 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
12480 when exact match is impossible due to invisible text, and the
12481 lines are truncated.
12483 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
12485 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
12488 2011-07-22 Eli Zaretskii <eliz@gnu.org>
12490 Fix a significant slow-down of cursor motion with C-n, C-p,
12491 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
12492 auto-repeat under bidi redisplay in fontified buffers.
12493 * xdisp.c (compute_stop_pos_backwards): New function.
12494 (next_element_from_buffer): Call compute_stop_pos_backwards to
12495 find a suitable prev_stop when we find ourselves before
12497 (reseat): Don't look for prev_stop, as that could mean a very long
12499 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
12500 <cached_disp_overlay_modiff>: Cache for last found display string
12502 (compute_display_string_pos): Return the cached position if asked
12503 about the same buffer in the same area of character positions, and
12504 the buffer wasn't changed since the time the display string
12505 position was cached.
12507 2011-07-22 Eli Zaretskii <eliz@gnu.org>
12509 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
12510 is an integer, which is important for empty lines. (Bug#9149)
12512 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
12514 * frame.c (Fmodify_frame_parameters): In tty case, update the
12515 default face if necessary (Bug#4238).
12517 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
12519 * editfns.c (Fstring_to_char): No need to explain what a character
12520 is in the docstring (Bug#6576).
12522 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
12524 * xml.c (parse_region): Make sure we always return a tree.
12526 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
12528 * xml.c (parse_region): If a document contains only comments,
12531 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
12533 * xml.c (make_dom): Return comments, too.

12540 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
12541 rather than fgets, and retry after EINTR. Otherwise, 'emacs
12542 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
12544 * s/openbsd.h (BROKEN_SIGIO): Define.
12545 * unexelf.c (unexec) [__OpenBSD__]:
12546 Don't update the .mdebug section of the Alpha COFF symbol table.
12548 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12550 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
12553 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
12555 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
12556 This fixes some race conditions on the permissions of any newly
12559 * alloc.c (valid_pointer_p): Use pipe, not open.
12560 This fixes some permissions issues when debugging.
12562 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
12563 If fchown fails to set both uid and gid, try to set just gid,
12564 as that is sometimes allowed. Adjust the file's mode to eliminate
12565 setuid or setgid bits that are inappropriate if fchown fails.
12567 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
12569 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

12575 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
12577 * lread.c (read_integer): Unread even EOF character.
12578 (read1): Likewise. Properly record start position of symbol.
12580 * lread.c (read1): Read `#:' as empty uninterned symbol if no
12581 symbol character follows.
12583 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
12585 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
12586 This works around a problem with the previous change to Fcopy_file.
12587 Recent glibc declares fchown with __attribute__((warn_unused_result)),
12588 and without this change, GCC might complain about discarding
12589 fchown's return value.
12591 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
12593 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
12595 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
12597 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
12599 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
12601 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
12602 it's used from the C level.
12604 * process.c: Use the same condition for POLL_FOR_INPUT in both
12605 keyboard.c and process.c (bug#1858).
12607 2011-07-09 Lawrence Mitchell <wence@gmx.li>
12609 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
12610 (Fgnutls_boot): Use it.
12612 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
12614 * doc.c (Fsubstitute_command_keys): Revert last change.
12616 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
12618 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
12619 quotes the next character, and doesn't affect other longer
12620 sequences (bug#8935).
12622 * lread.c (syms_of_lread): Clarify that is isn't only
12623 `eval-buffer' and `eval-defun' that's affected by
12624 `lexical-binding' (bug#8460).
12626 2011-07-15 Eli Zaretskii <eliz@gnu.org>
12628 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
12629 bidi redisplay when a line includes both an image and is truncated.
12631 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
12633 Fix minor problems found by static checking.
12634 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
12635 (elsz): Now a signed constant, not a size_t var. We prefer signed
12636 types to unsigned, to avoid integer comparison confusion. Without
12637 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
12638 "cannot optimize loop, the loop counter may overflow", a symptom
12640 * indent.c (Fvertical_motion): Mark locals as initialized.
12641 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
12643 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
12645 * search.c (Fre_search_backward): Mention `case-fold-search' in
12646 all the re_search_* functions (bug#8138).

12669 (display_string): If we need to ignore text properties of
12670 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
12671 original value of -1 will not work with bidi.)
12672 (compute_display_string_pos): First arg is now struct
12673 `text_pos *'; all callers changed. Support display properties on
12675 (compute_display_string_end): Support display properties on Lisp
12677 (init_iterator, reseat_1, reseat_to_string): Initialize the
12678 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
12679 when iterating on a string not from display properties).
12680 (compute_display_string_pos, compute_display_string_end):
12681 Fix calculation of the object to scan. Fixes an error when using
12683 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
12684 base_level_stop; instead, set base_level_stop to BEGV.
12685 Fixes crashes in vertical-motion.
12686 (next_element_from_buffer): Improve commentary for when
12687 the iterator is before prev_stop.
12688 (init_iterator): Initialize bidi_p from the default value of
12689 bidi-display-reordering, not from buffer-local value. Use the
12690 buffer-local value only if initializing for buffer iteration.
12691 (handle_invisible_prop): Support invisible properties on strings
12692 that are being bidi-reordered.

12711 parts of next_element_from_buffer, next_element_from_string, and
12712 next_element_from_c_string.
12713 (tool_bar_lines_needed, redisplay_tool_bar)
12714 (display_menu_bar): Force left-to-right direction. Add a FIXME

12729 pushed the iterator stack, restore the internal state of the bidi
12730 iterator by calling bidi_pop_it same number of times.
12731 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
12732 and we are bidi-iterating, don't decrement the iterator position;
12733 instead, set the first_elt flag in the bidi iterator, to produce
12735 (reseat_1): Remove redundant setting of string_from_display_prop_p.
12736 (push_display_prop): xassert that we are iterating a buffer.

12740 (push_display_prop): Set up the `unibyte' member of bidi_it.string
12741 correctly. Don't assume unibyte strings are not bidi-reordered.

12750 property. Fix a typo in popping stretch info. Add an assertion
12751 for verifying that the iterator position is in sync with the bidi
12753 (handle_single_display_spec, get_overlay_strings_1)

13165 (clone_per_buffer_values): Don't assume that
13166 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
13167 This isn't true in general, and it's particularly not true
13168 if Emacs is configured with --with-wide-int.
13169 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
13170 New macros, used in the buffer.c change.

13206 Random fixes. E.g., (random) never returned negative values.
13207 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
13208 subseconds part to the entropy, as that's a bit more random.
13209 Prefer signed to unsigned, since the signedness doesn't matter and
13210 in general we prefer signed. When given a limit, use a
13211 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
13212 latter isn't right if USE_2_TAGS_FOR_INTS.
13213 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
13214 not 0..VALMASK. Don't discard "excess" bits that random () returns.

13226 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
13227 This is more efficient than Ffile_directory_p and avoids a minor race.
13229 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
13231 * buffer.c (Foverlay_put): Say what the return value is
13234 * fileio.c (barf_or_query_if_file_exists): Check first if the file
13235 is a directory before asking whether to use the file name

13238 error be more correct.
13240 * fns.c (Frequire): Remove the mention of the .gz files, since
13241 that's installation-specific, but keep the mention of
13242 `get-load-suffixes'.

13246 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

13254 Qgnutls_bootprop_verify_error (which is no longer used).
13256 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
13257 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
13258 Also (re)move comments that are misplaced or no longer relevant.

13285 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
13287 * lread.c (syms_of_lread): Mention single symbols defined by
13288 `defvar' or `defconst' (bug#7154).

13321 (syms_of_keymap): Defsubr make-composed-keymap.
13322 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

13359 * eval.c (struct backtrace): Simplify and port the data structure.
13360 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
13361 signed bit field, as this assumption is not portable and it makes
13362 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
13363 "char debug_on_exit : 1" as this is not portable either; instead,
13364 use the portable "unsigned int debug_on_exit : 1". Remove unused
13365 member evalargs. Remove obsolete comments about cc bombing out.
13367 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

13455 * process.c (wait_reading_process_output): Bypass select if
13456 waiting for a cell while ignoring keyboard input, and input is
13457 pending. Suggested by Jan Djärv (Bug#8869).

13533 * print.c (printchar, strout): Check for string overflow.
13534 (PRINTPREPARE, printchar, strout):
13535 Don't set size unless allocation succeeds.
13537 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
13538 for sizes. Check for string overflow more accurately.
13539 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.

13542 * keyboard.h (struct keyboard.kbd_macro_bufsize):
13543 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

13547 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
13549 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
13551 * lread.c: Integer overflow fixes.
13552 (read_integer): Radix is now EMACS_INT, not int,
13553 to improve quality of diagnostics for out-of-range radices.
13554 Calculate buffer size correctly for out-of-range radices.
13555 (read1): Check for integer overflow in radices, and in
13556 read-circle numbers.
13557 (read_escape): Avoid int overflow.
13558 (Fload, openp, read_buffer_size, read1)
13559 (substitute_object_recurse, read_vector, read_list, map_obarray):

13575 2011-06-22 Leo Liu <sdl.web@gmail.com>
13577 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
13578 Move to minibuffer.el.
13580 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
13582 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
13583 The following patches are for when GLYPH_DEBUG && !XASSERT.
13584 * dispextern.h (trace_redisplay_p, dump_glyph_string):
13585 * dispnew.c (flush_stdout):
13586 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
13587 Mark as externally visible.
13588 * dispnew.c (check_window_matrix_pointers): Now static.
13589 * dispnew.c (window_to_frame_vpos):
13590 * xfns.c (unwind_create_frame):

13592 * scroll.c (CHECK_BOUNDS):
13593 * xfaces.c (cache_fache): Rename local to avoid shadowing.
13594 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
13595 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
13596 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
13597 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
13599 (debug_method_add): Use va_list and vsprintf rather than relying
13600 on undefined behavior with wrong number of arguments.
13601 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
13602 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
13603 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
13604 since we're not interested in debugging glyphs with old libraries.
13605 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
13606 GCC 4.6.0's static checking.
13608 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

13626 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
13627 (.bitmaps_last, struct x_output.icon_bitmap):
13628 Use ptrdiff_t, not int, for bitmap indexes.
13629 (x_allocate_bitmap_record): Check for size overflow.
13630 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
13632 Use ptrdiff_t, not int, for overlay counts.
13633 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
13634 * editfns.c (overlays_around, get_pos_property):

13636 * xdisp.c (next_overlay_change, note_mouse_highlight):
13637 * xfaces.c (face_at_buffer_position):
13638 * buffer.c (OVERLAY_COUNT_MAX): New macro.
13639 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
13640 (Fnext_overlay_change, Fprevious_overlay_change)
13641 (mouse_face_overlay_overlaps, Foverlays_in):
13642 Use ptrdiff_t, not int, for sizes.
13643 (overlays_at, overlays_in): Check for size-calculation overflow.
13645 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
13647 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
13648 (x_session_initialize): Do not assume string length fits in int.
13650 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
13651 This is unlikely, but can occur if DPI is outlandish.
13653 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
13654 * xselect.c (Fx_get_atom_name): Avoid need for strlen.

13657 * xrdb.c (magic_file_p, search_magic_path):
13658 Omit last arg SUFFIX; it was always 0. All callers changed.
13659 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
13661 * xfont.c (xfont_match): Avoid need for strlen.
13663 * xfns.c: Don't assume strlen fits in int.

13668 Detect integer overflow in repeat count.
13669 (message_dolog): Don't assume print length fits in 39 bytes.
13670 (display_mode_element): Don't assume strlen fits in int.
13672 * termcap.c: Don't assume sizes fit in int and never overflow.
13673 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
13674 (gobble_line): Check for size-calculation overflow.
13676 * minibuf.c (Fread_buffer):
13677 * lread.c (intern, intern_c_string):

13691 * filelock.c: Fix some buffer overrun and integer overflow issues.
13692 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
13693 Reformulate so as not to need the command string.
13694 Invoke gzip -cd rather than gunzip, as it's more portable.
13695 (lock_info_type, lock_file_1, lock_file):
13696 Don't assume pid_t and time_t fit in unsigned long.
13697 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
13698 (current_lock_owner): Prefer signed type for sizes.
13699 Use memcpy, not strncpy, where memcpy is what is really wanted.
13700 Don't assume (via atoi) that time_t and pid_t fit in int.
13701 Check for time_t and/or pid_t out of range, e.g., via a network share.
13702 Don't alloca where an auto var works fine.
13704 * fileio.c: Fix some integer overflow issues.
13705 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
13706 Don't assume string length fits in int.
13707 (directory_file_name): Don't assume string length fits in long.
13708 (make_temp_name): Don't assume pid fits in int, or that its print
13709 length is less than 20.

13729 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
13731 * lread.c (invalid_syntax): Omit length argument.
13732 All uses changed. This doesn't fix a bug, but it simplifies the
13733 code away from its former Hollerith-constant appearance, and it's
13734 one less 'int' to worry about when looking at integer-overflow issues.
13735 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
13737 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
13738 This didn't break anything, but it didn't help either.
13739 It's confusing to put a bogus integer in a place where the actual
13740 value does not matter.
13741 (LIST_END_P): Remove unused macro and its bogus comment.
13742 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
13744 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
13745 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
13747 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
13748 We prefer signed types, and the value cannot exceed the EMACS_INT
13749 range anyway (because otherwise the length would not be representable).
13750 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
13751 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
13752 This avoids a GCC warning when WIDE_EMACS_INT.
13754 * indent.c (sane_tab_width): New function.
13755 (current_column, scan_for_column, Findent_to, position_indentation)
13756 (compute_motion): Use it. This is just for clarity.
13757 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.

13763 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
13765 * editfns.c, insdel.c:
13766 Omit unnecessary forward decls, to simplify future changes.
13768 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
13770 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
13772 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
13773 Use much-faster test for byte-length change.
13774 Don't assume string byte-length fits in 'int'.
13775 Check that character arg fits in 'int'.
13776 (mapcar1): Declare byte as byte, for clarity.
13778 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
13780 * fns.c (concat): Catch string overflow earlier.
13781 Do not rely on integer wraparound.
13783 * dispextern.h (struct it.overlay_strings_charpos)
13784 (struct it.selective): Now EMACS_INT, not int.
13785 * xdisp.c (forward_to_next_line_start)
13786 (back_to_previous_visible_line_start)
13787 (reseat_at_next_visible_line_start, next_element_from_buffer):
13788 Don't arbitrarily truncate the value of 'selective' to int.
13790 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
13792 * composite.c: Don't truncate sizes to 'int'.
13793 (composition_gstring_p, composition_reseat_it)
13794 (composition_adjust_point): Use EMACS_INT, not int.
13795 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
13796 not EMACS_UINT, for indexes.
13798 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
13800 * buffer.c: Include <verify.h>.
13801 (struct sortvec.priority, struct sortstr.priority):
13802 Now EMACS_INT, not int.
13803 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
13804 (struct sortstr.size, record_overlay_string)
13805 (struct sortstrlist.size, struct sortlist.used):
13806 Don't truncate size to int.
13807 (record_overlay_string): Check for size-calculation overflow.
13808 (init_buffer_once): Check at compile-time, not run-time.
13810 2011-06-22 Jim Meyering <meyering@redhat.com>
13812 Don't leak an XBM-image-sized buffer
13813 * image.c (xbm_load): Free the image buffer after using it.
13815 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
13818 * composite.c (find_automatic_composition): Omit needless 'return 0;'
13819 that Sun C diagnosed.
13820 * fns.c (secure_hash): Fix pointer signedness issue.
13821 * intervals.c (static_offset_intervals): New function.
13822 (offset_intervals): Use it.
13824 2011-06-21 Leo Liu <sdl.web@gmail.com>
13827 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
13830 * fns.c (secure_hash): Rename from crypto_hash_function and change
13831 the first arg to accept symbols.
13832 (Fsecure_hash): New primitive.
13833 (syms_of_fns): New symbols.
13835 2011-06-20 Deniz Dogan <deniz@dogan.se>
13837 * process.c (Fset_process_buffer): Clarify return value in

13852 check till after the cache is created in init_frame_faces.
13854 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
13856 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
13858 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
13860 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
13861 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
13862 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
13864 Improve buffer-overflow checking (Bug#8873).
13865 * fileio.c (Finsert_file_contents):
13866 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
13867 Remove the old (too-loose) buffer overflow checks.
13868 They weren't needed, since make_gap checks for buffer overflow.
13869 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
13870 The old code merely checked for Emacs fixnum overflow, and relied
13871 on undefined (wraparound) behavior. The new code avoids undefined
13872 behavior, and also checks for ptrdiff_t and/or size_t overflow.
13874 * editfns.c (Finsert_char): Don't dump core with very negative counts.
13875 Tune. Don't use wider integers than needed. Don't use alloca.
13876 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
13878 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
13880 * insdel.c, lisp.h (buffer_overflow): New function.
13881 (insert_from_buffer_1, replace_range, replace_range_2):
13882 * insdel.c (make_gap_larger):
13883 * editfns.c (Finsert_char):
13884 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
13886 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
13888 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
13890 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
13892 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
13893 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
13895 * fileio.c: Don't assume EMACS_INT fits in off_t.
13896 (emacs_lseek): New static function.
13897 (Finsert_file_contents, Fwrite_region): Use it.
13898 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
13900 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
13902 * fns.c: Don't overflow int when computing a list length.
13903 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
13904 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
13905 truncation on 64-bit hosts. Check for QUIT every
13906 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
13907 faster and is responsive enough.
13908 (Flength): Report an error instead of overflowing an integer.
13909 (Fsafe_length): Return a float if the value is not representable
13910 as a fixnum. This shouldn't happen except in contrived situations.
13911 (Fnthcdr, Fsort): Don't assume list length fits in int.
13912 (Fcopy_sequence): Don't assume vector length fits in int.
13914 * alloc.c: Check that resized vectors' lengths fit in fixnums.
13915 (header_size, word_size): New constants.
13916 (allocate_vectorlike): Don't check size overflow here.
13917 (allocate_vector): Check it here instead, since this is the only
13918 caller of allocate_vectorlike that could cause overflow.
13919 Check that the new vector's length is representable as a fixnum.
13921 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
13922 The previous code was bogus. For example, next_almost_prime (32)
13923 returned 39, which is undesirable as it is a multiple of 3; and
13924 next_almost_prime (24) returned 25, which is a multiple of 5 so
13925 why was the code bothering to check for multiples of 7?
13927 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
13929 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
13931 Variadic C functions now count arguments with ptrdiff_t.
13932 This partly undoes my 2011-03-30 change, which replaced int with size_t.
13933 Back then I didn't know that the Emacs coding style prefers signed int.
13934 Also, in the meantime I found a few more instances where arguments
13935 were being counted with int, which may truncate counts on 64-bit
13936 machines, or EMACS_INT, which may be unnecessarily wide.
13937 * lisp.h (struct Lisp_Subr.function.aMANY)
13938 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
13939 Arg counts are now ptrdiff_t, not size_t.
13940 All variadic functions and their callers changed accordingly.
13941 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
13942 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
13943 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
13944 * callint.c (Fcall_interactively): Check arg count for overflow,
13945 to avoid potential buffer overrun. Use signed char, not 'int',
13946 for 'varies' array, so that we needn't bother to check its size
13947 calculation for overflow.
13948 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
13949 * eval.c (apply_lambda):
13950 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
13951 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
13952 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
13954 * callint.c (Fcall_interactively): Don't use index var as event count.
13956 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
13957 * mem-limits.h (SIZE): Remove; no longer used.
13959 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
13961 Remove unnecessary casts.
13962 * xterm.c (x_term_init):
13963 * xfns.c (x_set_border_pixel):
13964 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
13965 These aren't needed now that we assume ANSI C.
13967 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
13968 It's more likely to cause problems (due to unsigned overflow)
13971 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
13973 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
13975 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
13977 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
13979 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
13981 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
13983 GLYPH_CODE_FACE returns EMACS_INT, not int.
13984 * dispextern.h (merge_faces):
13985 * xfaces.c (merge_faces):
13986 * xdisp.c (get_next_display_element, next_element_from_display_vector):
13987 Don't assume EMACS_INT fits in int.
13989 * character.h (CHAR_VALID_P): Remove unused parameter.
13990 * fontset.c, lisp.h, xdisp.c: All uses changed.
13992 * editfns.c (Ftranslate_region_internal): Omit redundant test.
13994 * fns.c (concat): Minor tuning based on overflow analysis.
13995 This doesn't fix any bugs. Use int to hold character, instead
13996 of constantly refetching from Emacs object. Use XFASTINT, not
13997 XINT, for value known to be a character. Don't bother comparing
13998 a single byte to 0400, as it's always less.
14000 * floatfns.c (Fexpt):
14001 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
14003 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
14006 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
14008 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
14009 Without this fix, on a 64-bit host (aset S 0 4294967386) would
14010 incorrectly succeed when S was a string, because 4294967386 was
14011 truncated before it was used.
14013 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
14014 Otherwise, an out-of-range integer could cause undefined behavior
14017 * composite.c: Use int, not EMACS_INT, for characters.
14018 (fill_gstring_body, composition_compute_stop_pos): Use int, not
14019 EMACS_INT, for values that are known to be in character range.
14020 This doesn't fix any bugs but is the usual style inside Emacs and
14021 may generate better code on 32-bit machines.
14023 Make sure a 64-bit char is never passed to ENCODE_CHAR.
14024 This is for reasons similar to the recent CHAR_STRING fix.
14025 * charset.c (Fencode_char): Check that character arg is actually
14026 a character. Pass an int to ENCODE_CHAR.
14027 * charset.h (ENCODE_CHAR): Verify that the character argument is no
14028 wider than 'int', as a compile-time check to prevent future regressions
14031 * character.c (char_string): Remove unnecessary casts.
14033 Make sure a 64-bit char is never passed to CHAR_STRING.
14034 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
14035 by silently ignoring the top 32 bits, allowing some values
14036 that were far too large to be valid characters.
14037 * character.h: Include <verify.h>.
14038 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
14039 arguments are no wider than unsigned, as a compile-time check
14040 to prevent future regressions in this area.
14042 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
14043 (Fsubst_char_in_region):
14045 * xdisp.c (decode_mode_spec_coding):
14046 Adjust to CHAR_STRING's new requirement.
14047 * editfns.c (Finsert_char, Fsubst_char_in_region):
14048 * fns.c (concat): Check that character args are actually
14049 characters. Without this test, these functions did the wrong
14050 thing with wildly out-of-range values on 64-bit hosts.
14052 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
14053 These casts should not be needed on 32-bit hosts, either.
14054 * keyboard.c (read_char):
14055 * lread.c (Fload): Remove casts to unsigned.
14057 * lisp.h (UNSIGNED_CMP): New macro.
14058 This fixes comparison bugs on 64-bit hosts.
14059 (ASCII_CHAR_P): Use it.
14060 * casefiddle.c (casify_object):
14061 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
14062 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
14063 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
14064 * dispextern.h (FACE_FROM_ID):
14065 * keyboard.c (read_char): Use UNSIGNED_CMP.
14067 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
14068 not to EMACS_INT, to avoid GCC warning.
14070 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
14072 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
14073 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
14074 isn't needed on 32-bit machines.
14076 * buffer.c (Fgenerate_new_buffer_name):
14077 Use EMACS_INT for count, not int.
14078 (advance_to_char_boundary): Return EMACS_INT, not int.
14080 * data.c (Qcompiled_function): Now static.
14082 * window.c (window_body_lines): Now static.
14084 * image.c (gif_load): Rename local to avoid shadowing.
14086 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
14087 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
14088 * alloc.c (make_save_value): Integer argument is now of type
14089 ptrdiff_t, not int.
14090 (mark_object): Use ptrdiff_t, not int.
14091 * lisp.h (pD): New macro.
14092 * print.c (print_object): Use it.
14094 * alloc.c: Use EMACS_INT, not int, to count objects.
14095 (total_conses, total_markers, total_symbols, total_vector_size)
14096 (total_free_conses, total_free_markers, total_free_symbols)
14097 (total_free_floats, total_floats, total_free_intervals)
14098 (total_intervals, total_strings, total_free_strings):
14099 Now EMACS_INT, not int. All uses changed.
14100 (Fgarbage_collect): Compute overall total using a double, so that
14101 integer overflow is less likely to be a problem. Check for overflow
14102 when converting back to an integer.
14103 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
14104 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
14105 These were 'int' variables that could overflow on 64-bit hosts;
14106 they were never used, so remove them instead of repairing them.
14107 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
14108 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
14109 Previously, this ceilinged at INT_MAX, but that doesn't work on
14111 (allocate_pseudovector): Don't use EMACS_INT when int would do.
14113 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
14114 (allocate_vectorlike): Check for ptrdiff_t overflow.
14115 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
14116 when a (possibly-narrower) signed value would do just as well.
14117 We prefer using signed arithmetic, to avoid comparison confusion.
14119 * alloc.c: Catch some string size overflows that we were missing.
14120 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
14121 for convenience in STRING_BYTES_MAX.
14122 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
14123 The definition here is exact; the one in lisp.h was approximate.
14124 (allocate_string_data): Check for string overflow. This catches
14125 some instances we weren't catching before. Also, it catches
14126 size_t overflow on (unusual) hosts where SIZE_MAX <= min
14127 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
14128 and ptrdiff_t and EMACS_INT are both 64 bits.
14130 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
14131 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
14132 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
14134 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
14136 * alloc.c (Fmake_string): Check for out-of-range init.
14138 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
14140 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
14142 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
14144 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
14145 xg_get_default_scrollbar_width.
14147 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
14148 (int_gtk_range_get_value): Move to the scroll bar part of the file.
14149 (style_changed_cb): Call update_theme_scrollbar_width and call
14150 x_set_scroll_bar_default_width and xg_frame_set_char_size for
14151 all frames (Bug#8505).
14152 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
14153 Call gtk_window_set_resizable if HAVE_GTK3.
14154 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
14155 and height if HAVE_GTK3 (Bug#8505).
14156 (scroll_bar_width_for_theme): New variable.
14157 (update_theme_scrollbar_width): New function.
14158 (xg_get_default_scrollbar_width): Move code to
14159 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
14160 (xg_initialize): Call update_theme_scrollbar_width.
14162 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
14164 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
14166 2011-06-12 Martin Rudalics <rudalics@gmx.at>
14168 * frame.c (make_frame): Call other_buffer_safely instead of
14171 * window.c (temp_output_buffer_show): Call display_buffer with
14172 second argument Vtemp_buffer_show_specifiers and reset latter
14173 immediately after the call.
14174 (Vtemp_buffer_show_specifiers): New variable.
14175 (auto_window_vscroll_p, next_screen_context_lines)
14176 (Vscroll_preserve_screen_position): Remove leading asterisks from
14179 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
14181 Fix minor problems found by GCC 4.6.0 static checking.
14182 * buffer.c (Qclone_number): Remove for now, as it's unused.
14183 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
14184 (record_buffer): Remove unused local.
14185 * frame.c (other_visible_frames, frame_buffer_list): Now static.
14186 (set_frame_buffer_list): Remove; unused.
14187 * frame.h (other_visible_frames): Remove decl.
14188 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
14189 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
14190 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
14192 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
14193 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
14194 Define only if HAVE_GPM.
14195 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
14196 (update_hints_inhibit): Remove; never set. All uses removed.
14197 * widgetprv.h (emacsFrameClassRec): Remove decl.
14198 * window.c (delete_deletable_window): Now returns void, since it
14199 wasn't returning anything.
14200 (compare_window_configurations): Remove unused locals.
14201 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
14202 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
14203 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
14204 the same widths as pointers. This follows up on the 2011-05-06 patch.
14205 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
14206 * xterm.h: Likewise.
14207 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
14209 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
14211 * makefile.w32-in: Update dependencies.
14212 (LISP_H): Add lib/intprops.h.
14214 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
14216 * image.c (gif_load): Add animation frame delay to the metadata.
14217 (syms_of_image): Use DEFSYM. New symbol `delay'.
14219 2011-06-11 Martin Rudalics <rudalics@gmx.at>
14221 * window.c (delete_deletable_window): Re-add.
14222 (Fset_window_configuration): Rewrite to handle dead buffers and
14223 consequently deletable windows.
14224 (window_tree, Fwindow_tree): Remove. Supply functionality in
14226 (compare_window_configurations): Simplify code.
14228 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
14230 * image.c (imagemagick_load_image): Fix type mismatch.
14231 (Fimagemagick_types): Likewise.
14233 * window.h (replace_buffer_in_windows): Declare.
14235 2011-06-11 Martin Rudalics <rudalics@gmx.at>
14237 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
14238 Qclone_number. Remove external declaration of Qdelete_window.
14239 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
14241 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
14242 Run Qbuffer_list_update_hook if allowed.
14243 (Fother_buffer): Rewrite doc-string. Major rewrite for new
14244 buffer list implementation.
14245 (other_buffer_safely): New function.
14246 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
14247 calls to replace_buffer_in_windows and
14248 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
14250 (record_buffer): Inhibit quitting and rewrite using quittable
14251 functions. Run Qbuffer_list_update_hook if allowed.
14252 (Frecord_buffer, Funrecord_buffer): New functions.
14253 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
14254 Move switch-to-buffer to window.el.
14255 (bury-buffer): Move to window.el.
14256 (Vbuffer_list_update_hook): New variable.
14258 * lisp.h (other_buffer_safely): Add prototype in buffer.c
14261 * window.h (resize_frame_windows): Move up in code.
14262 (Fwindow_frame): Remove EXFUN.
14263 (replace_buffer_in_all_windows): Remove prototype.
14264 (replace_buffer_in_windows_safely): Add prototype.
14266 * window.c: Declare Qdelete_window static again. Move down
14267 declaration of select_count.
14268 (Fnext_window, Fprevious_window): Rewrite doc-strings.
14269 (Fother_window): Move to window.el.
14270 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
14271 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
14272 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
14274 (replace_buffer_in_windows): Implement by calling
14275 Qreplace_buffer_in_windows.
14276 (replace_buffer_in_all_windows): Remove with some functionality
14277 moved into replace_buffer_in_windows_safely.
14278 (replace_buffer_in_windows_safely): New function.
14279 (select_window_norecord, select_frame_norecord): Move in front
14280 of run_window_configuration_change_hook. Remove now obsolete
14282 (Fset_window_buffer): Rewrite doc-string.
14283 Call Qrecord_window_buffer.
14284 (keys_of_window): Move binding for other-window to window.el.
14286 2011-06-11 Chong Yidong <cyd@stupidchicken.com>

14732 (single_display_spec_string_p): Support property values that are
14733 lists with the argument STRING its top-level element.
14734 (display_prop_string_p): Fix the condition for processing a
14735 property that is a list to be consistent with handle_display_spec.
14736 (handle_display_spec): New function, refactored from the
14737 last portion of handle_display_prop.
14738 (compute_display_string_pos): Accept additional argument
14739 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
14740 value of a `display' property is a "replacing spec".
14741 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
14742 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
14743 the display property, but just return a value indicating whether
14744 the display property will replace the characters it covers.
14745 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
14746 frame_window_p members of struct bidi_it.
14747 (compute_display_string_pos, compute_display_string_end):
14749 (push_it): Accept second argument POSITION, where pop_it should
14750 jump to continue iteration.
14751 (reseat_1): Initialize bidi_it.disp_pos.
14753 * keyboard.c (adjust_point_for_property): Adjust the call to
14754 display_prop_intangible_p to its new signature.

14764 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
14766 Malloc failure behavior now depends on size of allocation.
14767 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
14768 * lisp.h: Change signatures accordingly.
14769 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
14770 All callers changed. (Bug#8762)
14772 * gnutls.c: Use Emacs's memory allocators.
14773 Without this change, the gnutls library would invoke malloc etc.
14774 directly, which causes problems on non-SYNC_INPUT hosts, and which
14775 runs afoul of improving memory_full behavior. (Bug#8761)
14776 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
14777 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
14778 xfree instead of the default malloc, realloc, free.
14779 (Fgnutls_boot): No need to check for memory allocation failure,
14780 since xmalloc does that for us.
14782 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
14783 * category.c (hash_get_category_set):
14784 * ccl.c (ccl_driver):
14785 * charset.c (Fdefine_charset_internal):

14797 (Fsxhash, Fgethash, Fputhash, Fmaphash):
14798 * image.c (make_image, search_image_cache, lookup_image)
14799 (xpm_put_color_table_h):
14800 * lisp.h (struct Lisp_Hash_Table):
14801 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
14802 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
14803 for hashes and hash indexes, instead of 'unsigned' and 'int'.
14804 * alloc.c (allocate_vectorlike):
14805 Check for overflow in vector size calculations.
14806 * ccl.c (ccl_driver):
14807 Check for overflow when converting EMACS_INT to int.
14808 * fns.c, image.c: Remove unnecessary static decls that would otherwise
14809 need to be updated by these changes.
14810 * fns.c (make_hash_table, maybe_resize_hash_table):
14811 Check for integer overflow with large hash tables.
14812 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
14813 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
14814 (SXHASH_REDUCE): New macro.
14815 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
14816 Use it instead of discarding useful hash info with large hash values.
14817 (sxhash_float): New function.
14818 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
14819 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
14820 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
14821 Rewrite to use FIXNUM_BITS, as this simplifies things.
14822 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
14823 Adjust signatures to match updated version of code.
14824 (consing_since_gc): Now EMACS_INT, since a single hash table can
14825 use more than INT_MAX bytes.
14827 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
14829 Make it possible to build with GCC-4.6+ -O2 -flto.
14831 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
14833 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
14835 * minibuf.c (get_minibuffer, read_minibuf_unwind):
14836 Call minibuffer-inactive-mode.
14838 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
14840 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
14841 Update dependencies.
14843 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14845 * data.c (init_data): Remove code for UTS, this system is not
14848 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14850 Don't force ./temacs to start in terminal mode.
14852 * frame.c (make_initial_frame): Initialize faces in all cases, not
14853 only when CANNOT_DUMP is defined.
14854 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
14856 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14858 * dispnew.c (add_window_display_history): Use const for the string
14859 pointer. Remove declaration, not needed.
14861 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
14863 Use 'inline', not 'INLINE'.
14864 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
14865 * alloc.c, fontset.c (INLINE): Remove.
14866 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
14867 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
14868 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
14869 * gmalloc.c (register_heapinfo): Use inline unconditionally.
14870 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
14872 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14874 Make it possible to run ./temacs.
14876 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
14877 syms_of_callproc does the same thing. Remove test for
14878 "initialized", do it in the caller.
14879 * emacs.c (main): Avoid calling set_initial_environment when dumping.
14881 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
14883 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
14884 (read_minibuf): Use get_minibuffer.
14885 (syms_of_minibuf): Use DEFSYM.
14886 (Qmetadata): New var.
14887 * data.c (Qbuffer): Don't make it static.
14888 (syms_of_data): Use DEFSYM.
14890 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
14892 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
14893 (CCL_CODE_MIN): New macro.
14895 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
14897 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
14899 * eval.c (Qdebug): Now static.
14900 * lisp.h (Qdebug): Remove decl. This reverts a part of the
14901 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
14902 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
14904 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14906 * image.c: Various fixes to ImageMagick code comments.
14907 (Fimagemagick_types): Doc fix.
14909 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
14911 Minor fixes prompted by GCC 4.6.0 warnings.
14913 * xselect.c (converted_selections, conversion_fail_tag): Now static.
14915 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
14916 (x_clipboard_manager_save_all): Move extern decl to ...
14917 * xterm.h: ... here, so that it can be checked for consistency.
14919 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14921 * xselect.c (x_clipboard_manager_save_frame)
14922 (x_clipboard_manager_save_all): New functions.
14923 (Fx_clipboard_manager_save): Lisp function deleted.
14925 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
14926 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
14928 * xterm.h: Update prototype.
14930 2011-05-28 William Xu <william.xwl@gmail.com>
14932 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
14933 exiting (Bug#8239).
14935 2011-05-28 Jim Meyering <meyering@redhat.com>
14937 Avoid a sign-extension bug in crypto_hash_function.
14938 * fns.c (to_uchar): Define.
14939 (crypto_hash_function): Use it to convert some newly-signed
14940 variables to unsigned, to avoid sign-extension bugs. For example,
14941 without this change, (md5 "truc") would evaluate to
14942 45723a2aff78ff4fff7fff1114760e62 rather than the expected
14943 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
14944 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
14946 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14948 Integer overflow fixes.
14950 * dbusbind.c: Serial number integer overflow fixes.
14951 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
14952 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
14953 to hold a serial number that is too large for a fixnum.
14954 (Fdbus_method_return_internal, Fdbus_method_error_internal):
14955 Check for serial numbers out of range. Decode any serial number
14956 that was so large that it became a float. (Bug#8722)
14958 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
14959 (Fdbus_call_method, Fdbus_call_method_asynchronously):
14960 Use XFASTINT rather than XUINT when numbers are nonnegative.
14961 (xd_append_arg, Fdbus_method_return_internal):
14962 (Fdbus_method_error_internal): Likewise. Also, for unsigned
14963 arguments, check that Lisp number is nonnegative, rather than
14964 silently wrapping negative numbers around. (Bug#8722)
14965 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
14968 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
14970 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
14972 ccl: Add integer overflow checks.
14973 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
14974 (IN_INT_RANGE): New macros.
14975 (ccl_driver): Use them to check for integer overflow when
14976 decoding a CCL program. Many of the new checks are whether XINT (x)
14977 fits in int; it doesn't always, on 64-bit hosts. The new version
14978 doesn't catch all possible integer overflows, but it's an
14979 improvement. (Bug#8719)
14981 * alloc.c (make_event_array): Use XINT, not XUINT.
14982 There's no need for unsigned here.
14984 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
14985 This follows up to the 2011-05-06 change that substituted uintptr_t
14986 for EMACS_INT. This case wasn't caught back then.
14988 Rework Fformat to avoid integer overflow issues.
14989 * editfns.c: Include <float.h> unconditionally, as it's everywhere
14990 now (part of C89). Include <verify.h>.
14991 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
14992 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
14993 (Fformat): Avoid the prepass trying to compute sizes; it was only
14994 approximate and thus did not catch overflow reliably. Instead, walk
14995 through the format just once, formatting and computing sizes as we go,
14996 checking for integer overflow at every step, and allocating a larger
14997 buffer as needed. Keep track separately whether the format is
14998 multibyte. Keep only the most-recently calculated precision, rather
14999 than them all. Record whether each argument has been converted to
15000 string. Use EMACS_INT, not int, for byte and char and arg counts.
15001 Support field widths and precisions larger than INT_MAX. Avoid
15002 sprintf's undefined behavior with conversion specifications such as %#d
15003 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
15004 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
15005 formatting out-of-range floating point numbers with int
15006 formats. (Bug#8668)
15008 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
15010 * data.c: Avoid integer truncation in expressions involving floats.
15011 * data.c: Include <intprops.h>.
15012 (arith_driver): When there's an integer overflow in an expression
15013 involving floating point, convert the integers to floating point
15014 so that the resulting value does not suffer from catastrophic
15015 integer truncation. For example, on a 64-bit host (* 4
15016 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
15017 Do not rely on undefined behavior after integer overflow.
15019 merge count_size_as_multibyte, parse_str_to_multibyte
15020 * character.c, character.h (count_size_as_multibyte):
15021 Rename from parse_str_to_multibyte; all uses changed.
15022 Check for integer overflow.
15023 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
15024 since it's now a duplicate of the other. This is more of
15025 a character than a buffer op, so better that it's in character.c.
15026 * fns.c, print.c: Adjust to above changes.
15028 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
15030 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
15032 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
15034 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
15035 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
15036 (x_clipboard_manager_save): Now static.
15037 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
15039 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
15040 (crypto_hash_function): Now static.
15041 Fix pointer signedness problems. Avoid unnecessary initializations.
15043 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
15045 * termhooks.h (Vselection_alist): Make it terminal-local.
15047 * terminal.c (create_terminal): Initialize it.
15049 * xselect.c: Support for clipboard managers.
15050 (Vselection_alist): Move to termhooks.h as terminal-local var.
15051 (LOCAL_SELECTION): New macro.
15052 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
15053 (symbol_to_x_atom): Remove gratuitous arg.
15054 (x_handle_selection_request, lisp_data_to_selection_data)
15055 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
15056 (x_own_selection, x_get_local_selection, x_convert_selection):
15057 New arg, specifying work frame. Use terminal-local Vselection_alist.
15058 (some_frame_on_display): Delete unused function.
15059 (Fx_own_selection_internal, Fx_get_selection_internal)
15060 (Fx_disown_selection_internal, Fx_selection_owner_p)
15061 (Fx_selection_exists_p): New optional frame arg.
15062 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
15063 (x_handle_selection_clear): Don't treat other terminals with the
15064 same keyboard specially. Use the terminal-local Vselection_alist.
15065 (x_clear_frame_selections): Use Frun_hook_with_args.
15067 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
15069 * xterm.h: Add support for those atoms.
15071 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
15073 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
15074 (converted_selections, conversion_fail_tag): New global variables.
15075 (x_selection_request_lisp_error): Free the above.
15076 (x_get_local_selection): Remove unnecessary code.
15077 (x_reply_selection_request): Args changed; handle arbitrary array
15078 of converted selections stored in converted_selections.
15079 Separate the XChangeProperty and SelectionNotify steps.
15080 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
15081 (x_convert_selection): New function.
15082 (x_handle_selection_event): Simplify.
15083 (x_get_foreign_selection): Don't ignore incoming requests while
15084 waiting for an answer; this will fail when we implement
15085 SAVE_TARGETS, and seems unnecessary anyway.
15086 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
15087 (Vx_sent_selection_functions): Doc fix.
15089 2011-05-26 Leo Liu <sdl.web@gmail.com>
15091 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
15093 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15095 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
15097 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
15098 for fringe update if it has periodic bitmap.
15099 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
15100 and fringe_bitmap_periodic_p.
15102 * fringe.c (get_fringe_bitmap_data): New function.
15103 (draw_fringe_bitmap_1, update_window_fringes): Use it.
15104 (update_window_fringes): Record periodicity of fringe bitmap in glyph
15105 row. Mark glyph row for fringe update if periodicity changed.
15107 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
15108 for fringe update unless it has periodic bitmap.
15110 2011-05-25 Kenichi Handa <handa@m17n.org>

15128 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
15129 Remove macros that are defined and never used.
15130 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
15132 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
15134 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
15135 (Fx_get_selection_internal): Minor cleanup.

15165 * systime.h (Time): Define only if emacs is defined.
15166 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
15167 where the include path doesn't have X11/X.h by default. See
15168 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
15170 2011-05-20 Kenichi Handa <handa@m17n.org>
15172 * composite.c (find_automatic_composition): Fix previous change.
15174 2011-05-20 Glenn Morris <rgm@gnu.org>
15176 * lisp.mk: New file, split from Makefile.in.
15177 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
15178 (shortlisp): Remove.
15179 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
15181 2011-05-19 Glenn Morris <rgm@gnu.org>
15183 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
15184 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
15185 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
15186 (lisp): Set the order to that of loadup.el.
15187 (shortlisp): Make it a copy of $lisp.
15188 (SOME_MACHINE_LISP): Remove.
15189 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
15190 Use just $shortlisp, not $SOME_MACHINE_LISP too.
15192 2011-05-18 Kenichi Handa <handa@m17n.org>
15194 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
15195 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
15196 (find_automatic_composition): Mostly rewrite for efficiency.
15198 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
15200 * makefile.w32-in: Update dependencies.
15202 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
15204 * menu.c: Include limits.h (fixes the MS-Windows build broken by
15205 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
15207 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
15209 Fix some integer overflow issues, such as string length overflow.
15211 * insdel.c (count_size_as_multibyte): Check for string overflow.
15213 * character.c (lisp_string_width): Check for string overflow.
15214 Use EMACS_INT, not int, for string indexes and lengths; in
15215 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
15216 the resulting string length overflows an EMACS_INT; instead,
15217 report a string overflow if no precision given. When checking for
15218 precision exhaustion, use a check that cannot possibly have
15219 integer overflow. (Bug#8675)
15220 * character.h (lisp_string_width): Adjust to new signature.
15222 * alloc.c (string_overflow): New function.
15223 (Fmake_string): Use it. This doesn't change behavior, but saves
15224 a few bytes and will simplify future changes.
15225 * character.c (string_escape_byte8): Likewise.
15226 * lisp.h (string_overflow): New decl.
15228 Fixups, following up to the user-interface timestamp change.
15229 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
15230 for UI timestamps, instead of unsigned long.
15231 * msdos.c (mouse_get_pos): Likewise.
15232 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
15233 * w32gui.h (Time): Define by including "systime.h" rather than by
15234 declaring it ourselves. (Bug#8664)
15236 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
15237 * image.c (clear_image_cache): Likewise.
15239 * term.c (term_mouse_position): Don't assume time_t wraparound.
15241 Be more systematic about user-interface timestamps.
15242 Before, the code sometimes used 'Time', sometimes 'unsigned long',
15243 and sometimes 'EMACS_UINT', to represent these timestamps.
15244 This change causes it to use 'Time' uniformly, as that's what X uses.
15245 This makes the code easier to follow, and makes it easier to catch
15246 integer overflow bugs such as Bug#8664.
15247 * frame.c (Fmouse_position, Fmouse_pixel_position):
15248 Use Time, not unsigned long, for user-interface timestamps.
15249 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
15250 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
15251 * keyboard.h (last_event_timestamp): Likewise.
15252 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
15253 * menu.h (xmenu_show): Likewise.
15254 * term.c (term_mouse_position): Likewise.
15255 * termhooks.h (struct input_event.timestamp): Likewise.
15256 (struct terminal.mouse_position_hook): Likewise.
15257 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
15258 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
15259 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
15260 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
15261 what it was before.
15262 * menu.h, termhooks.h: Include "systime.h", for Time.
15264 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
15265 Don't assume that the difference between two unsigned long values
15266 can fit into an integer. At this point, we know button_down_time
15267 <= event->timestamp, so the difference must be nonnegative, so
15268 there's no need to cast the result if double-click-time is
15269 nonnegative, as it should be; check that it's nonnegative, just in
15270 case. This bug is triggered when events are more than 2**31 ms
15271 apart (about 25 days). (Bug#8664)
15273 * xselect.c (last_event_timestamp): Remove duplicate decl.
15274 (x_own_selection): Remove needless cast to unsigned long.
15276 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
15277 that always fit in int. Use a sentinel instead of a counter, to
15278 avoid a temp and to allay GCC's concerns about possible int overflow.
15279 * frame.h (struct frame): Use int for menu_bar_items_used
15280 instead of EMACS_INT, since it always fits in int.
15282 * menu.c (grow_menu_items): Check for int overflow.
15284 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
15286 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
15287 Before, the code was not consistent. These values cannot exceed
15288 2**31 - 1 so there's no need to make them unsigned.
15289 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
15290 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
15291 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
15293 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
15295 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
15296 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
15297 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
15298 presumably because the widths might not match.
15300 * window.c (size_window): Avoid needless test at loop start.
15302 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
15304 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
15306 2011-05-12 Drew Adams <drew.adams@oracle.com>
15308 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
15310 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15312 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
15313 `width' to `bar_area_x' and `bar_area_width', respectively.
15314 (x_scroll_run): Take account of fringe background extension.
15316 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
15317 Rename local vars `left' and `width' to `bar_area_x' and
15318 `bar_area_width', respectively.
15319 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
15320 background extension.
15322 2011-05-10 Jim Meyering <meyering@redhat.com>
15324 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
15326 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
15328 * image.c (Finit_image_library): Return t for built-in image types,
15329 like pbm and xbm. (Bug#8640)
15331 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
15333 * w32menu.c (set_frame_menubar): Fix submenu allocation.
15335 2011-05-07 Eli Zaretskii <eliz@gnu.org>
15337 * w32console.c (Fset_screen_color): Doc fix.
15338 (Fget_screen_color): New function.
15339 (syms_of_ntterm): Defsubr it.
15341 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
15342 unlink the temporary file if Fcall_process didn't create it in the
15344 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
15345 child process will be redirected to a file specified with `:file'.
15346 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
15347 cue to call_process_cleanup not to close that handle.
15349 2011-05-07 Ben Key <bkey76@gmail.com>
15351 * makefile.w32-in: The bootstrap-temacs rule now makes use of
15352 one of two shell specific rules, either bootstrap-temacs-CMD or
15353 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
15354 to the previous implementation of the bootstrap-temacs rule.
15355 The bootstrap-temacs-CMD rule is similar to the previous
15356 implementation of the bootstrap-temacs rule except that it
15357 makes use of the ESC_CFLAGS variable instead of the CFLAGS
15360 These changes, along with some changes to nt/configure.bat,
15361 nt/gmake.defs, and nt/nmake.defs, are required to extend my
15362 earlier fix to add support for --cflags and --ldflags options
15363 that include quotes so that it works whether make uses cmd or
15366 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
15368 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
15369 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
15371 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
15372 a string. Handle both cases.
15373 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
15374 (Fdbus_register_method): Use Qinvalid_function.
15376 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
15378 * makefile.w32-in: Update dependencies.
15379 (LISP_H): Add inttypes.h and stdin.h.
15380 (PROCESS_H): Add unistd.h.
15382 2011-05-06 Eli Zaretskii <eliz@gnu.org>
15384 * lread.c: Include limits.h (fixes the MS-Windows build broken by
15385 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
15387 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
15389 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
15391 * term.c (vfatal): Remove stray call to va_end.
15392 It's not needed and the C Standard doesn't allow it here anyway.
15394 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
15395 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
15397 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
15400 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
15402 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15404 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
15406 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
15408 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
15410 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
15411 * charset.c (Fdefine_charset_internal): Don't initialize
15412 charset.code_space[15]. The value was garbage, on hosts with
15413 32-bit int (Bug#8600).
15415 * lread.c (read_integer): Be more consistent with string-to-number.
15416 Use string_to_number to do the actual conversion; this avoids
15417 rounding errors and fixes some other screwups. Without this fix,
15418 for example, #x1fffffffffffffff was misread as -2305843009213693952.
15419 (digit_to_number): Move earlier, for benefit of read_integer.
15420 Return -1 if the digit is out of range for the base, -2 if it is
15421 not a digit in any supported base. (Bug#8602)
15423 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
15425 * dispnew.c (scrolling_window): Return 1 if we scrolled,
15426 to match comment at start of function. This also removes a
15427 GCC warning about overflow in a 32+64-bit port.
15429 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
15431 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
15432 Reported by Stefan Monnier in
15433 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
15434 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
15435 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
15437 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
15438 (EMACS_UINTPTR): Likewise, with uintptr_t.
15440 * lisp.h: Prefer 64-bit EMACS_INT if available.
15441 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
15442 on 32-bit hosts that have 64-bit int, so that they can access
15444 However, temporarily disable this change unless the temporary
15445 symbol WIDE_EMACS_INT is defined.
15447 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
15449 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
15450 This removes an assumption that EMACS_INT and long are the same
15451 width as pointers. The assumption is true for Emacs porting targets
15452 now, but we want to make other targets possible.
15453 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
15454 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
15455 In the rest of the code, change types of integers that hold casted
15456 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
15457 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
15458 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
15459 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
15460 No need to cast type when ORing.
15461 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
15462 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
15463 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
15464 assume EMACS_INT is the same width as char *.
15465 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
15466 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
15467 Remove no-longer-needed casts.
15468 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
15469 (xg_tool_bar_help_callback, xg_make_tool_item):
15470 Use EMACS_INTPTR to hold an integer
15471 that will be cast to void *; this can avoid a GCC warning
15472 if EMACS_INT is not the same width as void *.
15473 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
15474 * xdisp.c (display_echo_area_1, resize_mini_window_1):
15475 (current_message_1, set_message_1):
15476 Use a local to convert to proper width without a cast.
15477 * xmenu.c (dialog_selection_callback): Likewise.
15479 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
15480 Also, don't assume VALBITS / RAND_BITS is less than 5,
15481 and don't rely on undefined behavior when shifting a 1 left into
15483 * lisp.h (get_random): Change signature to match.
15485 * lread.c (hash_string): Use size_t, not int, for hash computation.
15486 Normally we prefer signed values; but hashing is special, because
15487 it's better to use unsigned division on hash table sizes so that
15488 the remainder is nonnegative. Also, size_t is the natural width
15489 for hashing into memory. The previous code used 'int', which doesn't
15490 retain enough info to hash well into very large tables.
15491 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
15493 * dbusbind.c: Don't possibly lose pointer info when converting.
15494 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
15495 Use XPNTR rather than XHASH, so that the high-order bits of
15496 the pointer aren't lost when converting through void *.
15498 * eval.c (Fautoload): Don't double-shift a pointer.
15500 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
15502 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
15504 * gnutls.c (DEF_GNUTLS_FN):
15505 * image.c (DEF_IMGLIB_FN): Make function pointers static.
15507 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
15509 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
15512 2011-05-05 Eli Zaretskii <eliz@gnu.org>
15514 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
15515 New version that can reserve upto 2GB of heap space.
15517 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
15519 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
15521 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
15523 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
15524 `gnutls_certificate_set_x509_key_file'.
15526 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
15528 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
15529 Update dependencies.
15531 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15533 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
15534 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
15535 Remove unused parameter `fildes'.
15536 * process.c (read_process_output, send_process): Don't pass it.
15538 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15540 Fix previous change: the library cache is defined in w32.c.
15541 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
15542 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
15544 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15546 Implement dynamic loading of GnuTLS on Windows.
15548 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
15549 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
15550 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
15553 * gnutls.c (Qgnutls_dll): Define.
15554 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
15555 (gnutls_*): Declare function pointers.
15556 (init_gnutls_functions): New function to initialize function pointers.
15557 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
15558 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
15559 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
15560 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
15561 (emacs_gnutls_write, emacs_gnutls_read)
15562 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
15563 (Fgnutls_available_p): New function.
15564 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
15565 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
15566 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
15568 * image.c: Include w32.h.
15569 (Vimage_type_cache): Delete.
15570 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
15571 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
15572 (w32_delayed_load): Move to w32.c.
15574 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
15576 * w32.c (QCloaded_from, Vlibrary_cache): Define.
15577 (w32_delayed_load): Move from image.c. When loading a library, record
15578 its filename in the :loaded-from property of the library id.
15579 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
15580 Initialize and staticpro them.
15581 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
15583 * process.c: Include lisp.h before w32.h, not after.
15584 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
15585 instead of gnutls_record_check_pending.
15587 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
15589 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
15591 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
15592 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists

15637 rather than `XVECTOR (FOO)->size'.
15639 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
15640 inttypes.h, as a gnulib replacement is used if it not available in
15643 2011-04-21 Eli Zaretskii <eliz@gnu.org>
15645 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.

15655 charbuf for the composition carryover bytes.
15657 2011-04-21 Eli Zaretskii <eliz@gnu.org>

15662 %llo or %llx format is passed. (Bug#8545)
15664 * window.c (window_scroll_line_based): Use a marker instead of
15665 simple variables to record original value of point. (Bug#7952)
15667 * doprnt.c (doprnt): Fix the case where a multibyte sequence
15668 produced by %s or %c overflows available buffer space. (Bug#8545)
15670 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
15672 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
15673 (SIZE_MAX): Move defn after all includes, as they might #define it.
15675 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15677 * w32.c (init_environment): Warn about defaulting HOME to C:\.
15679 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15681 * keyboard.c (Qdelayed_warnings_hook): Define.
15682 (command_loop_1): Run `delayed-warnings-hook'
15683 if Vdelayed_warnings_list is non-nil.
15684 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
15685 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
15687 2011-04-28 Eli Zaretskii <eliz@gnu.org>
15689 * doprnt.c (doprnt): Don't return value smaller than the buffer
15690 size if the message was truncated. (Bug#8545).
15692 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15694 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

15697 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15699 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
15701 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
15703 * makefile.w32-in: Update dependencies.
15705 2011-04-27 Eli Zaretskii <eliz@gnu.org>
15707 Improve `doprnt' and its usage. (Bug#8545)
15708 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
15709 `format_end'. Remove support for %l as a conversion specifier.
15710 Don't use xrealloc. Improve diagnostics when the %l size modifier
15711 is used. Update the commentary.
15713 * eval.c (verror): Simplify calculation of size_t.
15715 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
15718 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
15720 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
15723 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15725 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
15726 This makes this file independent of the recent pseudovector change.
15728 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
15730 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
15732 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
15733 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
15734 Remove unused local.
15735 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
15737 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
15738 GCC 4.6.0 optimizes based on type-based alias analysis.
15739 For example, if b is of type struct buffer * and v of type struct
15740 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
15741 != &v->size, and therefore "v->size = 1; b->size = 2; return
15742 v->size;" must therefore return 1. This assumption is incorrect
15743 for Emacs, since it type-puns struct Lisp_Vector * with many other
15744 types. To fix this problem, this patch adds a new type struct
15745 vectorlike_header that documents the constraints on layout of vectors
15746 and pseudovectors, and helps optimizing compilers not get fooled
15747 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
15748 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
15749 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
15751 (XSETPVECTYPE): Rewrite in terms of new macro.
15752 (XSETPVECTYPESIZE): New macro, specifying both type and size.
15753 This is a bit clearer, and further avoids the possibility of
15754 undesirable aliasing.
15755 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
15756 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
15757 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
15758 since Lisp_Subr is a special case (no "next" field).
15759 (ASIZE): Now uses header.size rather than size.
15760 All previous uses of XVECTOR (foo)->size replaced to use this macro,
15761 to avoid the hassle of writing XVECTOR (foo)->header.size.
15762 (struct vectorlike_header): New type.
15763 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
15764 object, to help avoid aliasing.
15765 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
15766 (SUBRP): Likewise, since Lisp_Subr is a special case.
15767 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
15768 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
15769 (struct Lisp_Hash_Table): Combine first two members into a single
15770 struct vectorlike_header member. All uses of "size" and "next" members
15771 changed to be "header.size" and "header.next".
15772 * buffer.h (struct buffer): Likewise.
15773 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
15774 * frame.h (struct frame): Likewise.
15775 * process.h (struct Lisp_Process): Likewise.
15776 * termhooks.h (struct terminal): Likewise.
15777 * window.c (struct save_window_data, struct saved_window): Likewise.
15778 * window.h (struct window): Likewise.
15779 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
15780 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
15781 * buffer.c (init_buffer_once): Likewise.
15782 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
15784 * process.c (Fformat_network_address): Use local var for size,
15787 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
15789 Make the Lisp reader and string-to-float more consistent (Bug#8525)
15790 * data.c (atof): Remove decl; no longer used or needed.
15791 (digit_to_number): Move to lread.c.
15792 (Fstring_to_number): Use new string_to_number function, to be
15793 consistent with how the Lisp reader treats infinities and NaNs.
15794 Do not assume that floating-point numbers represent EMACS_INT
15795 without losing information; this is not true on most 64-bit hosts.
15796 Avoid double-rounding errors, by insisting on integers when
15797 parsing non-base-10 numbers, as the documentation specifies.
15798 * lisp.h (string_to_number): New decl, replacing ...
15799 (isfloat_string): Remove.
15800 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
15801 (read1): Do not accept +. and -. as integers; this
15802 appears to have been a coding error. Similarly, do not accept
15803 strings like +-1e0 as floating point numbers. Do not report
15804 overflow for integer overflows unless the base is not 10 which
15805 means we have no simple and reliable way to continue.
15806 Break out the floating-point parsing into a new
15807 function string_to_number, so that Fstring_to_number parses
15808 floating point numbers consistently with the Lisp reader.
15809 (digit_to_number): Move here from data.c. Make it static inline.
15810 (E_CHAR, EXP_INT): Remove, replacing with ...
15811 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
15812 (string_to_number): New function, replacing isfloat_string.
15813 This function checks for valid syntax and produces the resulting
15814 Lisp float number too. Rework it so that string-to-number
15815 no longer mishandles examples like "1.0e+". Use strtoumax,
15816 so that overflow for non-base-10 numbers is reported only when
15817 there's no portable and simple way to convert to floating point.
15819 * textprop.c (set_text_properties_1): Rewrite for clarity,
15820 and to avoid GCC warning about integer overflow.
15822 * intervals.h (struct interval): Use EMACS_INT for members
15823 where EMACS_UINT might cause problems. See
15824 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
15825 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
15826 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
15828 (offset_intervals): Tell GCC not to worry about length overflow
15829 when negating a negative length.
15831 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
15832 (overrun_check_free): Likewise.
15834 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
15835 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
15838 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15839 (gnutls_make_error): Rename local to avoid shadowing.
15840 (gnutls_emacs_global_deinit): ifdef out; not used.
15841 (Fgnutls_boot): Use const for pointer to readonly storage.
15842 Comment out unused local. Fix pointer signedness problems.
15844 * lread.c (openp): Don't stuff size_t into an 'int'.
15845 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
15846 about possible signed overflow.
15848 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15849 (GDK_KEY_g): Don't define if already defined.
15850 (xg_prepare_tooltip): Avoid pointer signedness problem.
15851 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
15853 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
15854 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
15856 * xfns.c (Fx_window_property): Simplify a bit,
15857 to make a bit faster and to avoid GCC 4.6.0 warning.
15858 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
15860 * fns.c (internal_equal): Don't assume size_t fits in int.
15862 * alloc.c (compact_small_strings): Tighten assertion a little.
15864 Replace pEd with more-general pI, and fix some printf arg casts.
15865 * lisp.h (pI): New macro, generalizing old pEd macro to other
15866 conversion specifiers. For example, use "...%"pI"d..." rather
15867 than "...%"pEd"...".
15868 (pEd): Remove. All uses replaced with similar uses of pI.
15869 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
15870 * alloc.c (check_pure_size): Don't overflow by converting size to int.
15871 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
15872 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
15873 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
15874 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
15875 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
15877 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
15878 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
15879 * print.c (safe_debug_print, print_object): Likewise.
15880 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
15882 Use pI instead of if-then-else-abort. Use %p to avoid casts,
15883 avoiding the 0 flag, which is not portable.
15884 * process.c (Fmake_network_process): Use pI to avoid cast.
15885 * region-cache.c (pp_cache): Likewise.
15886 * xdisp.c (decode_mode_spec): Likewise.
15887 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
15888 behavior on 64-bit hosts with printf arg.
15889 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
15890 (x_stop_queuing_selection_requests): Likewise.
15891 (x_get_window_property): Don't truncate byte count to an 'int'
15894 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
15895 here, since it parses constructs like leading '-' and spaces,
15896 which are not wanted; and it overflows with large numbers.
15897 Instead, simply match F[0-9]+, which is what is wanted anyway.
15899 * alloc.c: Remove unportable assumptions about struct layout.
15900 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
15901 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
15902 (allocate_vectorlike, make_pure_vector): Use the new macros,
15903 plus offsetof, to remove unportable assumptions about struct layout.
15904 These assumptions hold on all porting targets that I know of, but
15905 they are not guaranteed, they're easy to remove, and removing them
15906 makes further changes easier.
15908 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
15909 This doesn't fix a bug but makes the code clearer.
15910 (string_overrun_cookie): Now const. Use initializers that
15911 don't formally overflow signed char, to avoid warnings.
15912 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
15913 can cause Emacs to crash when string overrun checking is enabled.
15914 (allocate_buffer): Don't assume sizeof (struct buffer) is a
15915 multiple of sizeof (EMACS_INT); it need not be, if
15916 alignof(EMACS_INT) < sizeof (EMACS_INT).
15917 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
15919 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

15932 * eval.c (Qdebug): Restore global linkage.
15933 * keyboard.c (debug-on-event): New variable.
15934 (handle_user_signal): Break into debugger when debug-on-event
15935 matches the current signal symbol.
15937 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
15939 * alloc.c (check_sblock, check_string_bytes)
15940 (check_string_free_list): Convert to standard C.
15942 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
15944 * w32.c (emacs_gnutls_push): Fix typo.
15946 2011-04-25 Eli Zaretskii <eliz@gnu.org>
15948 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
15949 "cast to pointer from integer of different size".
15951 Improve doprnt and its use in verror. (Bug#8545)
15952 * doprnt.c (doprnt): Document the set of format control sequences
15953 supported by the function. Use SAFE_ALLOCA instead of always
15956 * eval.c (verror): Don't limit the buffer size at size_max-1, that
15957 is one byte too soon. Don't use xrealloc; instead xfree and
15960 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
15962 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
15965 * gnutls.c: Renamed global_initialized to
15966 gnutls_global_initialized. Added internals for the
15967 :verify-hostname-error, :verify-error, and :verify-flags
15968 parameters of `gnutls-boot' and documented those parameters in the
15969 docstring. Start callback support.
15970 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
15971 unless a fatal error occurred. Call gnutls_alert_send_appropriate
15972 on error. Return error code.
15973 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
15974 (emacs_gnutls_read): Likewise.
15975 (Fgnutls_boot): Return handshake error code.
15976 (emacs_gnutls_handle_error): New function.
15977 (wsaerror_to_errno): Likewise.
15979 * w32.h (emacs_gnutls_pull): Add prototype.
15980 (emacs_gnutls_push): Likewise.
15982 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
15983 (emacs_gnutls_push): Likewise.
15985 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
15987 * process.c (wait_reading_process_output): Check if GnuTLS
15988 buffered some data internally if no FDs are set for TLS
15991 * makefile.w32-in (OBJ2): Add gnutls.$(O).
15992 (LIBS): Link to USER_LIBS.
15993 ($(BLD)/gnutls.$(0)): New target.

15997 * xdisp.c (handle_single_display_spec): Rename the
15998 display_replaced_before_p argument into display_replaced_p, to
15999 make it consistent with the commentary. Fix typos in the
16002 * textprop.c (syms_of_textprop): Remove dead code.

16008 to changes in oldXMenu/XMenu.h from 2011-04-16.
16009 <menu_help_message, prev_menu_help_message>: Constify.
16010 (IT_menu_make_room): menu->help_text is now `const char **';

16075 codepoint of an invalid character, to avoid displaying a bogus
16078 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
16079 `error', not SYMBOL_NAME itself.

16086 FINAL_CHAR is a character, and use %c when it is passed as
16087 argument to `error'.
16089 2011-04-23 Eli Zaretskii <eliz@gnu.org>
16091 * s/ms-w32.h (localtime): Redirect to sys_localtime.

16153 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
16154 by pacifying GCC about it. Maybe it's time to retire it?

16277 ns_descriptor_to_entity that were caused by using free to
16278 deallocate memory blocks that were allocated by xmalloc (via

16299 (emacs_read, emacs_write): Use it.
16300 * process.c (send_process): Adjust to the new signatures of
16301 emacs_write and emacs_gnutls_write. Do not attempt to store

16494 * font.c (font_close_object): Now static.
16495 * font.h (font_close_object): Remove.
16496 * fontset.c (FONTSET_OBJLIST): Remove.
16497 (free_realized_fontset) #if-0 the body, which does nothing.

16499 * fontset.h (face_suitable_for_char_p): Remove decl.
16500 * xfaces.c (face_at_string_position):
16501 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
16502 since 0 is always ASCII.
16504 * fns.c (weak_hash_tables): Now static.

16525 * editfns.c, lisp.h (get_operating_system_release): Remove.
16526 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
16527 worth the hassle of breaking this out.
16529 * xterm.c: Make symbols static if they're not exported.
16530 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

16633 * buffer.c (buffer_count): Remove unused var.

16644 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
16645 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
16646 was inaccessible from Lisp.
16647 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
16648 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
16650 alloc.c: Import and export fewer symbols, and remove unused items.
16651 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
16653 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
16654 it's not optimized away by whole-program optimization.

16666 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
16667 (mark_backtrace): Define only if BYTE_MARK_STACK.
16668 * xdisp.c (message_enable_multibyte): Now static.
16670 Declare Lisp_Object Q* variables to be 'static' if not exported.
16671 This makes it easier for human readers (and static analyzers)
16672 to see whether these variables are used from other modules.
16673 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
16674 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

16683 Remove decls of unexported vars.
16684 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
16686 * lisp.h (DEFINE_FUNC): Make sname 'static'.
16688 Make Emacs functions such as Fatom 'static' by default.
16689 This makes it easier for human readers (and static analyzers)
16690 to see whether these functions can be called from other modules.
16691 DEFUN now defines a static function. To make the function external
16692 so that it can be used in other C modules, use the new macro DEFUE.
16693 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
16694 (Finit_image_library):
16695 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
16696 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
16697 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
16698 Remove decls, since these functions are now static.
16699 (Funintern, Fget_internal_run_time): New decls, since these functions
16700 were already external.
16702 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

16709 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
16710 Mark functions with DEFUE instead of DEFUN,
16711 if they are used in other modules.
16712 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
16713 decls for now-static functions.
16714 * buffer.h (Fdelete_overlay): Remove decl.

16724 * image.c (Finit_image_library): New forward static decl.
16725 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
16726 * intervals.h (Fprevious_property_change):
16727 (Fremove_list_of_text_properties): Remove decls.
16728 * keyboard.c (Fthis_command_keys): Remove decl.
16729 (Fcommand_execute): New forward static decl.

16750 2011-04-13 Eli Zaretskii <eliz@gnu.org>
16752 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
16753 when at ZV. (Bug#8487)
16755 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
16757 * charset.c (Fclear_charset_maps): Use xfree instead of free.

16763 * xsettings.c (read_and_apply_settings): Likewise.
16765 * alloc.c (overrun_check_malloc, overrun_check_realloc)
16766 (overrun_check_free): Protoize.
16768 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
16770 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
16771 since callers should never pass a negative size.
16772 Change the signature to match that of plain 'read' and 'write'; see
16773 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
16774 * lisp.h: Update prototypes of emacs_write and emacs_read.
16776 2011-04-11 Eli Zaretskii <eliz@gnu.org>
16778 * xdisp.c (redisplay_window): Don't try to determine the character
16779 position of the scroll margin if the window start point w->startp
16780 is outside the buffer's accessible region. (Bug#8468)
16782 2011-04-10 Eli Zaretskii <eliz@gnu.org>
16784 Fix write-region and its subroutines for buffers > 2GB.
16785 * fileio.c (a_write, e_write): Modify declaration of arguments and
16786 local variables to support buffers larger than 2GB.
16787 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
16789 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
16790 argument, local variables, and return value.
16792 * lisp.h: Update prototypes of emacs_write and emacs_read.
16794 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
16796 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
16798 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
16800 Fix more problems found by GCC 4.6.0's static checks.
16802 * xdisp.c (vmessage): Use a better test for character truncation.
16804 * charset.c (load_charset_map): <, not <=, for optimization,
16805 and to avoid potential problems with integer overflow.
16806 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
16807 * casetab.c (set_identity, shuffle): Likewise.
16808 * editfns.c (Fformat): Likewise.
16809 * syntax.c (skip_chars): Likewise.
16811 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
16812 This also lets GCC 4.6.0 generate slightly better loop code.
16814 * callint.c (Fcall_interactively): <, not <=, for optimization.
16815 (Fcall_interactively): Count the number of arguments produced,
16816 not the number of arguments given. This is simpler and lets GCC
16817 4.6.0 generate slightly better code.
16819 * ftfont.c: Distingish more carefully between FcChar8 and char.
16820 The previous code passed unsigned char * to a functions like
16821 strlen and xstrcasecmp that expect char *, which does not
16822 conform to the C standard.
16823 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
16824 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
16825 char * when the C standard requires it.
16827 * keyboard.c (read_char): Remove unused var.
16829 * eval.c: Port to Windows vsnprintf (Bug#8435).
16830 Include <limits.h>.
16831 (SIZE_MAX): Define if the headers do not.
16832 (verror): Do not give up if vsnprintf returns a negative count.
16833 Instead, grow the buffer. This ports to Windows vsnprintf, which
16834 does not conform to C99. Problem reported by Eli Zaretskii.
16835 Also, simplify the allocation scheme, by avoiding the need for
16836 calling realloc, and removing the ALLOCATED variable.
16838 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
16840 Remove invocations of doprnt, as Emacs now uses vsnprintf.
16841 But keep the doprint source code for now, as we might revamp it
16842 and use it again (Bug#8435).
16843 * lisp.h (doprnt): Remove.
16844 * Makefile.in (base_obj): Remove doprnt.o.
16845 * deps.mk (doprnt.o): Remove.
16847 error: Print 32- and 64-bit integers portably (Bug#8435).
16848 Without this change, on typical 64-bit hosts error ("...%d...", N)
16849 was used to print both 32- and 64-bit integers N, which relied on
16850 undefined behavior.
16851 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
16852 * lisp.h (error, verror): Mark as printf-like functions.
16853 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
16854 Report overflow in size calculations when allocating printf buffer.
16855 Do not truncate output string at its first null byte.
16856 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
16857 Truncate the output at a character boundary, since vsnprintf does not
16859 * charset.c (check_iso_charset_parameter): Convert internal
16860 character to string before calling 'error', since %c now has the
16862 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
16863 overflow when computing char to be passed to 'error'. Do not
16864 pass Lisp_Object to 'error'; pass the integer instead.
16865 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
16866 formatted with plain %d.
16868 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
16870 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
16872 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
16874 * xterm.c (x_catch_errors): Remove duplicate declaration.
16876 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
16878 * xdisp.c, lisp.h (message_nolog): Remove; unused.
16880 2011-04-10 Jim Meyering <meyering@redhat.com>
16882 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
16883 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
16884 return ssize_t not "int", and use size_t as the buffer length.
16885 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
16886 * gnutls.h: Update declarations.
16887 * process.c (read_process_output): Use ssize_t, to match.
16888 (send_process): Likewise.
16890 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16892 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
16894 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16896 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):

16904 2011-04-09 Eli Zaretskii <eliz@gnu.org>
16906 Fix some uses of `int' instead of EMACS_INT.
16907 * search.c (string_match_1, fast_string_match)
16908 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
16909 (scan_buffer, find_next_newline_no_quit)
16910 (find_before_next_newline, search_command, Freplace_match)

16960 instead of using internal_with_output_to_temp_buffer.
16961 (Qhelp_form_show): New var.
16962 (syms_of_keyboard): Use DEFSYM macro.
16964 * print.c (internal_with_output_to_temp_buffer): Function deleted.

17000 * eval.c (Fsignal): Remove excess argument to 'fatal'.
17002 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
17003 This avoids several warnings with gcc -Wstrict-overflow.
17004 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
17005 directly, rather than having caller test rule sign. This avoids
17006 some unnecessary tests.
17007 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
17008 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
17009 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
17011 * xfont.c (xfont_text_extents): Remove var that was set but not used.
17012 (xfont_open): Avoid unnecessary tests.
17014 * composite.c (composition_gstring_put_cache): Use unsigned integer.
17016 * composite.h, composite.c (composition_gstring_put_cache):
17017 Use EMACS_INT, not int, for length.
17019 * composite.h (COMPOSITION_DECODE_REFS): New macro,
17020 breaking out part of COMPOSITION_DECODE_RULE.
17021 (COMPOSITION_DECODE_RULE): Use it.
17022 * composite.c (get_composition_id): Remove unused local vars,
17023 by using the new macro.
17025 * textprop.c (set_text_properties_1): Change while to do-while,
17026 since the condition is always true at first.
17028 * intervals.c (graft_intervals_into_buffer): Mark var as used.
17029 (interval_deletion_adjustment): Return unsigned value.
17032 * process.c (list_processes_1, create_pty, read_process_output):
17033 (exec_sentinel): Remove vars that were set but not used.
17034 (create_pty): Remove unnecessary "volatile"s.
17035 (Fnetwork_interface_info): Avoid possibility of int overflow.

17048 * print.c (print_error_message): Avoid int overflow.
17050 * font.c (font_list_entities): Redo for clarity,
17051 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
17053 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
17054 (font_score): Avoid potential overflow in diff calculation.

17057 (sxhash): Redo loop for clarity and to avoid wraparound warning.
17059 * eval.c (funcall_lambda): Rename local to avoid shadowing.
17061 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
17062 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
17063 can always succeed if overflow has undefined behavior.
17065 * search.c (boyer_moore, wordify): Remove vars set but not used.
17066 (wordify): Omit three unnecessary tests.
17068 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

17077 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
17078 (Finsert_file_contents): Remove unnecessary code checking fd.
17080 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
17081 Check for integer overflow on size calculations.
17083 * buffer.c (Fprevious_overlay_change): Remove var that is set
17086 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
17087 Remove vars that are set but not used.
17088 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
17089 (timer_check_2): Mark vars as initialized.
17091 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
17093 * image.c (lookup_image): Remove var that is set but not used.
17094 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
17096 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
17097 that are set but not used.
17099 * xfns.c (make_invisible_cursor): Don't return garbage
17100 if XCreateBitmapFromData fails (Bug#8410).
17102 * xselect.c (x_get_local_selection, x_handle_property_notify):
17103 Remove vars that are set but not used.
17105 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
17106 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
17108 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
17109 Remove var that is set but not used.
17110 (scroll_bar_windows_size): Now size_t, not int.
17111 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
17112 Check for overflow.
17114 * xfaces.c (realize_named_face): Remove vars that are set but not used.
17115 (map_tty_color) [!defined MSDOS]: Likewise.
17117 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
17119 * coding.c: Remove vars that are set but not used.
17120 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
17121 All callers changed.
17122 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
17123 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
17124 (decode_coding_charset): Remove vars that are set but not used.
17126 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
17127 that is set but not used.
17129 * print.c (print_object): Remove var that is set but not used.
17131 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
17132 The gnulib version avoids calling malloc in the usual case,
17133 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
17134 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
17135 * filelock.c (current_lock_owner): Likewise.
17136 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
17137 * sysdep.c: Include allocator.h, careadlinkat.h.
17138 (emacs_no_realloc_allocator): New static constant.
17139 (emacs_readlink): New function.
17140 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
17141 ../lib/careadlinkat.h.
17143 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
17145 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
17146 first non-nil return value).

17150 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
17151 if not defined (Bug#8403).
17153 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
17155 * xdisp.c (display_count_lines): Remove parameter `start',
17156 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
17157 (get_char_face_and_encoding): Remove parameter `multibyte_p',
17158 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

17160 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
17161 and thereabouts. All callers changed.
17162 (get_per_char_metric): Remove parameter `f', unused since
17163 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
17165 2011-04-02 Jim Meyering <meyering@redhat.com>
17167 do not dereference NULL upon failed strdup
17168 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
17169 (ns_get_family): Likewise.
17171 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
17173 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
17175 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
17177 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
17180 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
17182 Add lexical binding.
17184 * window.c (Ftemp_output_buffer_show): New fun.
17185 (Fsave_window_excursion):
17186 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
17188 * lread.c (lisp_file_lexically_bound_p): New function.
17189 (Fload): Bind Qlexical_binding.
17190 (readevalloop): Remove `evalfun' arg.
17191 Bind Qinternal_interpreter_environment.
17192 (Feval_buffer): Bind Qlexical_binding.
17193 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
17195 (syms_of_lread): Declare `lexical-binding'.
17197 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
17199 * keyboard.c (eval_dyn): New fun.
17200 (menu_item_eval_property): Use it.
17202 * image.c (parse_image_spec): Use Ffunctionp.
17204 * fns.c (concat, mapcar1): Accept byte-code-functions.
17206 * eval.c (Fsetq): Handle lexical vars.
17207 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
17208 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
17209 (FletX, Flet): Obey lexical binding.
17210 (Fcommandp): Handle closures.
17211 (Feval): New `lexical' arg.
17212 (eval_sub): New function extracted from Feval. Use it almost
17213 everywhere where Feval was used. Look up vars in lexical env.
17215 (Ffunctionp): Move from subr.el.
17216 (Ffuncall): Handle closures.
17217 (apply_lambda): Remove `eval_flags'.
17218 (funcall_lambda): Handle closures and new byte-code-functions.
17219 (Fspecial_variable_p): New function.
17220 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
17221 but without exporting it to Lisp.
17223 * doc.c (Fdocumentation, store_function_docstring):
17224 * data.c (Finteractive_form): Handle closures.
17226 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
17229 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
17231 (exec_byte_code): New function extracted from Fbyte_code to handle new
17232 calling convention for byte-code-functions. Add new byte-codes.
17234 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
17236 * alloc.c (Fmake_symbol): Init new `declared_special' field.
17238 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
17240 * xdisp.c (redisplay_internal): Fix prototype.
17242 2011-03-31 Eli Zaretskii <eliz@gnu.org>
17244 * xdisp.c (SCROLL_LIMIT): New macro.
17245 (try_scrolling): Use it when setting scroll_limit.
17246 Limit scrolling to 100 screen lines.
17247 (redisplay_window): Even when falling back on "recentering",
17248 position point in the window according to scroll-conservatively,
17249 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
17251 (try_scrolling): When point is above the window, allow searching
17252 as far as scroll_max, or one screenful, to compute vertical
17253 distance from PT to the scroll margin position. This prevents
17254 try_scrolling from unnecessarily failing when
17255 scroll-conservatively is set to a value slightly larger than the
17256 window height. Clean up the case of PT below the margin at bottom
17257 of window: scroll_max can no longer be INT_MAX. When aggressive
17258 scrolling is in use, don't let point enter the opposite scroll
17259 margin as result of the scroll.
17260 (syms_of_xdisp) <scroll-conservatively>: Document the
17261 threshold of 100 lines for never-recentering scrolling.
17263 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
17265 * dispextern.h (move_it_by_lines):
17266 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
17267 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
17268 (message_log_check_duplicate): Remove parameters `prev_bol' and
17269 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
17270 (redisplay_internal): Remove parameter `preserve_echo_area',
17271 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
17273 * indent.c (Fvertical_motion):
17274 * window.c (window_scroll_pixel_based, Frecenter):
17275 Don't pass `need_y_p' to `move_it_by_lines'.
17277 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
17279 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
17280 steal a few bits to be more compact.
17281 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
17282 Remove unneeded casts.
17284 * bytecode.c (Fbyte_code): CAR and CDR can GC.
17286 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
17288 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
17289 binding" message (bug#7967).
17291 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
17293 Fix more problems found by GCC 4.6.0's static checks.
17295 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
17296 Remove unused local var.
17298 * editfns.c (Fmessage_box): Remove unused local var.
17300 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
17301 (note_mode_line_or_margin_highlight, note_mouse_highlight):
17302 Omit unused local vars.
17303 * window.c (shrink_windows): Omit unused local var.
17304 * menu.c (digest_single_submenu): Omit unused local var.
17305 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
17306 Omit unused local var.
17308 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
17309 Don't assume string length fits in int.
17310 (keyremap_step, read_key_sequence): Use size_t for sizes.
17311 (read_key_sequence): Don't check last_real_key_start redundantly.
17313 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
17314 instead of alloca (Bug#8344).
17316 * eval.c (Fbacktrace): Don't assume nargs fits in int.
17317 (Fbacktrace_frame): Don't assume nframes fits in int.
17319 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
17321 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
17324 * term.c (produce_glyphless_glyph): Remove unnecessary test.
17326 * cm.c (calccost): Turn while-do into do-while, for clarity.
17328 * keyboard.c (syms_of_keyboard): Use the same style as later
17329 in this function when indexing through an array. This also
17330 works around GCC bug 48267.
17332 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
17334 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
17336 * chartab.c (sub_char_table_ref_and_range): Redo for slight
17337 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
17339 * keyboard.c, keyboard.h (num_input_events): Now size_t.
17340 This avoids undefined behavior on integer overflow, and is a bit
17341 more convenient anyway since it is compared to a size_t variable.
17343 Variadic C functions now count arguments with size_t, not int.
17344 This avoids an unnecessary limitation on 64-bit machines, which
17345 caused (substring ...) to crash on large vectors (Bug#8344).
17346 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
17347 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
17348 All variadic functions and their callers changed accordingly.
17349 (struct gcpro.nvars): Now size_t, not int. All uses changed.

17568 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
17570 (command_loop_1): Use Frun_hooks. Call safe_run_hooks

17575 Fix more problems found by GCC 4.5.2's static checks.
17577 * coding.c (encode_coding_raw_text): Avoid unnecessary test
17578 the first time through the loop, since we know p0 < p1 then.
17579 This also avoids a gcc -Wstrict-overflow warning.
17581 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
17582 leading to a memory leak, possible in functions like
17583 load_charset_map_from_file that can allocate an unbounded number
17584 of objects (Bug#8318).
17586 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
17587 that could (at least in theory) be that large.
17589 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
17590 This is less likely to overflow, and avoids undefined behavior if
17591 overflow does occur. All callers changed. Use strtoul to scan

17609 * process.c (Fmake_network_process): Use socklen_t, not int,
17610 where POSIX says socklen_t is required in portable programs.
17611 This fixes a porting bug on hosts like 64-bit HP-UX, where
17612 socklen_t is wider than int (Bug#8277).
17613 (Fmake_network_process, server_accept_connection):
17614 (wait_reading_process_output, read_process_output):

17629 Include tparam.h instead, since it declares them.

17631 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
17632 * terminfo.c: Include tparam.h, to check interfaces.
17633 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
17634 (tparam): Adjust signature to match interface in tparam.h;
17635 this removes some undefined behavior. Check that outstring and len
17636 are zero, which they always are with Emacs.
17637 * tparam.h (PC, BC, UP): New extern decls.
17639 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
17640 (xftfont_open): Rename locals to avoid shadowing.

17680 (alsa_choose_format): Remove unused local var.
17681 (wav_play): Initialize a variable to 0, to prevent undefined
17682 behavior (Bug#8278).
17684 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
17686 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
17688 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
17689 clobbering (Bug#8298).
17690 * sysdep.c (sys_subshell): Likewise.
17691 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
17693 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
17694 This should get cleaned up, so that child_setup has the
17695 same signature on all platforms.
17697 * callproc.c (call_process_cleanup): Now static.
17698 (relocate_fd): Rename locals to avoid shadowing.
17700 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
17702 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
17703 not to be necessary, and produces flickering.

17707 * config.in: Remove file.
17709 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

17754 Define only if needed.
17756 * unexelf.c (unexec): Name an expression,
17757 to avoid gcc -Wbad-function-cast warning.
17758 Use a different way to cause a compilation error if anyone uses
17759 n rather than nn, a way that does not involve shadowing.
17760 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
17762 * deps.mk (unexalpha.o): Remove; unused.

17810 * alloc.c (mark_backtrace): Move decl from here ...
17811 * lisp.h: ... to here, so that it can be checked.
17813 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
17814 (Fdefvar): Rewrite so as not to use empty "else".
17815 (lisp_indirect_variable): Name an expression,
17816 to avoid gcc -Wbad-function-cast warning.
17817 (Fdefvar): Rename locals to avoid shadowing.
17819 * callint.c (quotify_arg, quotify_args): Now static.
17820 (Fcall_interactively): Rename locals to avoid shadowing.

17827 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
17828 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
17829 some of which prompt warnings from gcc -Wbad-function-cast.
17830 (Fformat_time_string, Fencode_time, Finsert_char):
17831 (Ftranslate_region_internal, Fformat):
17832 Rename or remove local vars to avoid shadowing.

17858 (GC_STRING_CHARS): Remove; not used.
17859 (Fmemory_limit): Cast sbrk's returned value to char *.
17861 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
17862 avoids undefined behavior in theory.
17864 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
17866 Use functions, not macros, for up- and down-casing (Bug#8254).
17867 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
17868 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
17869 to use the following functions instead of these macros.
17870 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
17871 EMACS_INT, since callers assume the returned value fits in int.
17872 (upcase1): Likewise, for UPCASE_TABLE.
17873 (uppercasep, lowercasep, upcase): New static inline functions.
17874 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

17884 (regex_compile, re_match_2_internal): Mark locals as initialized.
17885 (RETALLOC_IF): Define only if needed.
17886 (WORDCHAR_P): Likewise. This one is never needed, but is used
17887 only in a comment talking about a compiler bug, so put inside
17888 the #if 0 of that comment.
17889 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
17890 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

17916 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
17917 New macros, so that the caller can use some names other than
17918 gcpro1, gcpro2, etc.
17919 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
17921 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
17922 argument, for consistency with GCPRO2_VAR, etc: it is now the
17923 prefix of the variable, not the variable itself. All uses
17925 * dired.c (directory_files_internal, file_name_completion):
17926 Rename locals to avoid shadowing.
17928 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
17929 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
17930 dired.c's scmp function, had undefined behavior.
17931 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
17932 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
17933 * buffer.h: ... to here, because these macros use current_buffer,
17934 and the new implementation with inline functions needs to have
17935 current_buffer in scope now, rather than later when the macros
17937 (downcase, upcase1): New static inline functions.
17938 (DOWNCASE, UPCASE1): Reimplement using these functions.
17939 This avoids undefined behavior in expressions like
17940 DOWNCASE (x) == DOWNCASE (y), which previously suffered
17941 from race conditions in accessing the global variables
17942 case_temp1 and case_temp2.
17943 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
17944 * lisp.h (case_temp1, case_temp2): Remove their decls.
17945 * character.h (ASCII_CHAR_P): Move from here ...
17946 * lisp.h: ... to here, so that the inline functions mentioned
17947 above can use them.
17949 * dired.c (directory_files_internal_unwind): Now static.
17951 * fileio.c (file_name_as_directory, directory_file_name):
17952 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
17954 (file_name_as_directory): Use const pointers when appropriate.
17955 (Fexpand_file_name): Likewise. In particular, newdir might
17956 point at constant storage, so make it a const pointer.
17957 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
17958 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
17960 (Fset_file_times, Finsert_file_contents, auto_save_error):

17965 to avoid shadowing.
17967 * marker.c (bytepos_to_charpos): Remove; unused.
17969 * lisp.h (verify_bytepos, count_markers): New decls,
17970 so that gcc does not warn that these functions aren't declared.
17972 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
17973 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
17974 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
17975 (copy_text): Remove unused local var.
17977 * filelock.c (within_one_second): Now static.
17978 (lock_file_1): Rename local to avoid shadowing.
17980 * buffer.c (fix_overlays_before): Mark locals as initialized.
17981 (fix_start_end_in_overlays): Likewise. This function should be
17982 simplified by using pointers-to-pointers, but that's a different
17984 (switch_to_buffer_1): Now static.
17985 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
17986 (report_overlay_modification): Rename locals to avoid shadowing.

17989 Fix pointer signedness issue.
17990 (sys_subshell): Mark local as volatile if checking for lint,
17991 to suppress a gcc -Wclobbered warning that does not seem to be right.
17992 (MAXPATHLEN): Define only if needed.
17994 * process.c (serial_open, serial_configure): Move decls from here ...
17995 * systty.h: ... to here, so that they can be checked.
17997 * fns.c (get_random, seed_random): Move extern decls from here ...
17998 * lisp.h: ... to here, so that they can be checked.
18000 * sysdep.c (reset_io): Now static.

18009 (describe_map_tree):
18010 Rename locals to avoid shadowing.
18012 * keyboard.c: Declare functions static if they are not used elsewhere.

18159 For example, without this patch (encode-time 0 0 0 1 1
18160 1152921504606846976) returns the obviously-bogus value (-948597
18161 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
18162 reports time overflow. See
