3 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
5 2012-10-05 Eli Zaretskii <eliz@gnu.org>
7 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
9 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
10 that time stamps of directories could also be changed. Don't
11 request the too broad GENERIC_WRITE, only the more restrictive
12 FILE_WRITE_ATTRIBUTES access rights.
14 * fileio.c (Fset_file_times): Special-case ignoring errors for
15 directories only on MSDOS, not on MS-Windows.
17 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
19 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
21 2012-10-04 Eli Zaretskii <eliz@gnu.org>
23 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
24 see whether CreateFile failed.
26 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
28 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
29 to avoid similar races.
30 * keyboard.c (pending_signals): Now bool, not int.
32 Port timers to OpenBSD, plus check for timer failures.
33 OpenBSD problem reported by Han Boetes.
34 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
36 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
37 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
38 like OpenBSD, which has timer_settime but does not declare it.
39 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
40 whether to use itimerspec-related primitives. All uses of
41 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
43 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
45 * profiler.c (handle_profiler_signal): Fix a malloc race
46 that caused Emacs to hang on Fedora 17 when profiling Lisp.
48 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
50 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
52 2012-10-02 Eli Zaretskii <eliz@gnu.org>
54 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
55 consistent with the change in return value of 'safe_strsignal'.
57 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
59 Prefer plain 'static' to 'static inline' (Bug#12541).
60 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
61 (bidi_set_sor_type, bidi_push_embedding_level)
62 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

67 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
68 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
69 Now 'static', not 'static inline'.
71 Count overruns when profiling; change units to ns.
72 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
73 Give extra weight to samples after overruns, to attempt to count
74 the time more accurately.
75 (setup_cpu_timer): Change sampling interval units from ms to ns, since
76 the underlying primitives nominally do ns.
77 (Fprofiler_cpu_start): Document the change. Mention that
78 the sampling intervals are only approximate.
80 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
82 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
84 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
85 case for the special 0 coding-system.
87 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
88 (Fmake_overlay): Remove redundant tests.
89 (fix_start_end_in_overlays): Remove redundant recentering.
91 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
93 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
96 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
98 Fix a malloc race condition involving strsignal.
99 A signal can arrive in the middle of a malloc, and Emacs's signal
100 handler can invoke strsignal, which can invoke malloc, which is
101 not portable. This race condition bug makes Emacs hang on GNU/Linux.
102 Fix it by altering the signal handler so that it does not invoke
104 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
105 * process.c (status_message): Use const pointer, in case strsignal
106 is #defined to safe_strsignal.
107 * sysdep.c (sys_siglist, init_signals): Always define and
108 initialize a substitute sys_siglist if the system does not define
109 one, even if HAVE_STRSIGNAL.
110 (safe_strsignal): Rename from strsignal. Always define,
111 using sys_siglist. Return a const pointer.
112 * syssignal.h (safe_strsignal): New decl.
113 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
115 2012-10-01 Eli Zaretskii <eliz@gnu.org>
117 * w32proc.c (timer_loop): Fix code that waits for timer
118 expiration, to avoid high CPU usage.
120 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
122 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
123 (sweep_weak_table): Remove redundant prototypes.
125 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
127 * emacs.c: Move the inclusion of TERM_HEADER after including
128 windows.h on WINDOWSNT. This avoids compilation problems with
131 2012-10-01 Eli Zaretskii <eliz@gnu.org>
133 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
134 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
135 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
136 as the previous version used 'void *'.
138 * ralloc.c (ROUNDUP): Fix last change.
139 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
142 * w32proc.c <disable_itimers>: New static flag.
143 (init_timers): Initialize it to zero, after creating the critical
144 sections used by the timer threads.
145 (term_timers): Set to 1 before deleting the critical sections.
146 (getitimer, setitimer): If disable_itimers is non-zero, return an
147 error indication without doing anything. Reported by Fabrice
148 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
149 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
151 [!HAVE_SETITIMER]: Behave as the previous version that didn't
154 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
155 term_ntproc after all the other bookkeeping, to get timers working
158 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
160 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
161 Suggested by Juri Linkov in
162 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
164 Prefer plain 'static' to 'static inline' (Bug#12541).
165 With static functions, modern compilers inline pretty well by
166 themselves; advice from programmers often hurts as much as it helps.
167 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
168 this change shrinks the text size of the Emacs executable by 1.1%
169 without affecting CPU significantly in my benchmark.

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

462 All uses changed to store the new value.
463 (handle_profiler_signal): Rename from sigprof_handler_1,
464 for consistency with other handlers. Do not check whether
465 cpu_log is a hash-table if garbage collecting, since it

468 for consistency with other handlers.
469 (setup_cpu_timer): New function, with much of what used to be in

471 Prefer timer_settime if available, and prefer
472 thread cputime clocks, then process cputime clocks, then
473 monotonic clocks, to the old realtime clock. Use make_timeval
474 to round more-correctly when falling back to setitimer.
475 (Fprofiler_cpu_start): Use it.
476 (Fprofiler_cpu_stop): Prefer timer_settime if available.
477 Don't assume that passing NULL as the 2nd argument of setitimer
478 is the same as passing a pointer to all-zero storage.
479 Ignore SIGPROF afterwards.
480 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
481 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
482 non-fatal signal handlers. Ignore SIGPROF on startup.
483 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
484 in profiler.c, since sysdep.c now uses it.
486 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
487 Suggested by Eli Zaretskii in

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

577 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
579 Prefer POSIX timers if available.
580 They avoid a race if the timer is too close to the current time.
581 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
582 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.

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

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

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

748 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
749 fatal_error_backtrace.
751 * w32proc.c (sys_kill): Undo last change: don't do anything when
752 invoked to deliver SIGABRT to our own process. This is now
753 handled by emacs_raise.
755 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
757 * w32term.c (w32_read_socket): Remove leftover reference to
758 interrupt_input_pending.
760 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
762 Do not use SA_NODEFER.
763 Problem reported by Dani Moncayo in
764 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
766 * sysdep.c (emacs_abort): Do not reset signal handler.
767 * emacs.c (terminate_due_to_signal): Reset signal handler here.
768 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
769 wanted even on POSIXish hosts, and it doesn't work on Windows.
771 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
773 * xterm.c (x_term_init): Call fixup_locale before and after calling
774 gtk_init (Bug#12392).
776 2012-09-23 Chong Yidong <cyd@gnu.org>
778 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
779 Vdynamic_library_alist.
781 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
782 (Fgnutls_available_p): Caller changed.
784 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
785 (Flibxml_parse_xml_region): Likewise.
787 * dispextern.h (struct image_type): Remove arg from init function.
789 * image.c (Finit_image_library, lookup_image_type)

791 (init_xpm_functions, init_png_functions, init_jpeg_functions)
792 (init_tiff_functions, init_gif_functions, init_svg_functions):
793 Arglist and w32_delayed_load calling convention changed.
794 (gs_type): Remove init_gs_functions; there is no such function.
795 (valid_image_p, make_image): Fix caller to lookup_image_type.
797 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
799 Simplify and avoid signal-handling races (Bug#12471).
801 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
802 Avoid recursive loop if there's a fatal error in the function itself.
803 * atimer.c (pending_atimers):
804 * blockinput.h: Don't include "atimer.h"; no longer needed.
805 (interrupt_input_pending): Remove. All uses removed.
806 pending_signals now counts both atimers and ordinary interrupts.
807 This is less racy than having three separate pending-signal flags.
808 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
810 Rename from their upper-case counterparts BLOCK_INPUT,
811 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
812 INPUT_BLOCKED_P, and turn into functions. All uses changed.
813 This makes it easier to access volatile variables more accurately.
814 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
815 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
816 that's more reliable if the code is buggy and sets
817 interrupt_input_blocked to a negative value. All uses changed.
818 * atimer.c (deliver_alarm_signal):
819 Remove. No need to deliver this to the parent; any thread can
820 handle this signal now. All uses replaced by underlying handler.
821 * atimer.c (turn_on_atimers):
822 * dispnew.c (handle_window_change_signal):
823 * emacs.c (handle_danger_signal):
824 * keyboard.c (kbd_buffer_get_event):
825 Don't reestablish signal handler; not needed with sigaction.
826 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
828 Rework to avoid unnecessary accesses to volatile variables.
829 (UNBLOCK_INPUT_TO): Now a function.
830 (totally_unblock_input, unblock_input): New decls.
831 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
832 (init_data): Remove. Necessary stuff now done in init_signal.
833 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
834 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
835 (fatal_error_code): Remove; no longer needed.
836 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
837 it doesn't always backtrace. All uses changed. No need to reset
838 signal to default, since sigaction and/or die does that for us now.
839 Use emacs_raise (FOO), not kill (getpid (), FOO).
840 (main): Check more-accurately whether we're dumping.
841 Move fatal-error setup to sysdep.c
842 * floatfns.c: Do not include "syssignal.h"; no longer needed.
843 * gtkutil.c (xg_get_file_name, xg_get_font):
844 Remove no-longer-needed signal-mask manipulation.
845 * keyboard.c, process.c (POLL_FOR_INPUT):
846 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
847 * keyboard.c (read_avail_input): Remove.
848 All uses replaced by gobble_input.
849 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
850 (kbd_buffer_store_event_hold, gobble_input):
851 (record_asynch_buffer_change) [USABLE_SIGIO]:
852 (store_user_signal_events):
853 No need to mess with signal mask.
854 (gobble_input): If blocking input and there are terminals, simply
855 set pending_signals to 1 and return. All hooks changed to not
856 worry about whether input is blocked.
857 (process_pending_signals): Clear pending_signals before processing
858 them, in case a signal comes in while we're processing.
859 By convention callers now test pending_signals before calling us.
860 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
861 New functions, to support changes to blockinput.h.
862 (handle_input_available_signal): Now extern.
863 (reinvoke_input_signal): Remove. All uses replaced by
865 (quit_count): Now volatile, since a signal handler uses it.
866 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
867 All callers changed. Block SIGINT only if not already blocked.
868 Clear sigmask reliably, even if Fsignal returns, which it can.
869 Omit unnecessary accesses to volatile var.
870 (quit_throw_to_read_char): No need to restore sigmask.
871 * keyboard.c (gobble_input, handle_user_signal):
872 * process.c (wait_reading_process_output):
873 Call signal-handling code rather than killing ourselves.
874 * lisp.h: Include <float.h>, for...
875 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
876 (pending_signals): Now volatile.
877 (syms_of_data): Now const if IEEE floating point.
878 (handle_input_available_signal) [USABLE_SIGIO]:
879 (terminate_due_to_signal, record_child_status_change): New decls.
880 * process.c (create_process): Avoid disaster if memory is exhausted
881 while we're processing a vfork, by tightening the critical section
883 (send_process_frame, process_sent_to, handle_pipe_signal)
884 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
886 (send_process): No need for setjmp/longjmp any more, since the
887 SIGPIPE stuff is now gone. Instead, report an error if errno
889 (record_child_status_change): Now extern. PID and W are now args.
890 Return void, not bool. All callers changed.
891 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
892 Remove. All uses removed. This bug should be fixed now in a
894 (wait_for_termination_1): Use waitpid rather than sigsuspend,
895 and record the child status change directly. This avoids the
896 need to futz with the signal mask.
897 (process_fatal_action): Move here from emacs.c.
898 (emacs_sigaction_flags): New function, containing
899 much of what used to be in emacs_sigaction_init.
900 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
901 caught by emacs, to make races less likely.
902 (deliver_process_signal): Rename from handle_on_main_thread.
904 (BACKTRACE_LIMIT_MAX): Now at top level.
905 (thread_backtrace_buffer, threadback_backtrace_pointers):
907 (deliver_thread_signal, deliver_fatal_thread_signal):
908 New functions, for more-accurate delivery of thread-specific signals.
909 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
910 (deliver_arith_signal): Handle in this thread, not
911 in the main thread, since it's triggered by this thread.
912 (maybe_fatal_sig): New function.
913 (init_signals): New arg DUMPING so that we can be more accurate
914 about whether we're dumping. Caller changed.
915 Treat thread-specific signals differently from process-general signals.
916 Block all signals while handling fatal error; that's safer.
917 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
919 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
920 Ignore SIGPIPE unless batch.
921 (emacs_backtrace): Output backtrace for the appropriate thread,
922 which is not necessarily the main thread.
923 * syssignal.h: Include <stdbool.h>.
924 (emacs_raise): New macro.
925 * xterm.c (x_connection_signal): Remove; no longer needed
926 now that we use sigaction.
927 (x_connection_closed): No need to mess with sigmask now.
928 (x_initialize): No need to reset SIGPIPE handler here, since
929 init_signals does this for us now.
931 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
933 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
934 background rect may be larger (Bug#12245).
936 2012-09-23 Chong Yidong <cyd@gnu.org>
938 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
940 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
942 * .gdbinit: Just stop at fatal_error_backtrace.
943 See Stefan Monnier's request in
944 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
945 Remove no-longer-used query of system type.
947 2012-09-22 Chong Yidong <cyd@gnu.org>
949 * search.c (Freplace_match): Doc fix (Bug#12325).
951 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
953 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
954 (Fline_end_position): Doc fix.
956 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
958 2012-09-22 Chong Yidong <cyd@gnu.org>
960 * dispextern.h (struct image_type): Add new slot, storing a type
961 initialization function.
963 * image.c (define_image_type): Call the image initializer function
964 if it is defined. Arguments and return value changed.
965 (valid_image_p, make_image): Callers changed.
966 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
967 (gif_type, imagemagick_type, svg_type, gs_type):
968 Add initialization functions.
969 (Finit_image_library): Call lookup_image_type.
970 (CHECK_LIB_AVAILABLE): Macro deleted.
971 (lookup_image_type): Call define_image_type here, rather than via
972 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
973 (syms_of_image): Move define_image_type calls for xbm_type and
974 pbm_type to lookup_image_type.
976 2012-09-22 Eli Zaretskii <eliz@gnu.org>
978 * keyboard.c (timer_check_2): Move calculation of 'timers' and
979 'idle_timers' from here ...
980 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
981 lists, to avoid infloops when the timer does something stupid,
982 like reinvoke itself with the same or smaller time-out.
985 2012-09-22 Martin Rudalics <rudalics@gmx.at>
987 * window.c (Fsplit_window_internal): Handle only Qt value of
988 Vwindow_combination_limit separately.
989 (Qtemp_buffer_resize): New symbol.
990 (Vwindow_combination_limit): New default value.
993 2012-09-22 Eli Zaretskii <eliz@gnu.org>
995 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
996 the new overlay string. (Bug#10159)
998 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1000 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
1001 or that fprintf is async-signal-safe. POSIX doesn't require
1004 2012-09-22 Chong Yidong <cyd@gnu.org>
1006 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
1009 2012-09-22 Kenichi Handa <handa@gnu.org>
1011 * composite.c (composition_reseat_it): Handle the case that a
1012 grapheme cluster is not covered by a single font (Bug#12352).
1014 2012-09-21 Chong Yidong <cyd@gnu.org>
1016 * image.c (define_image_type): Avoid adding duplicate types to
1017 image_types (Bug#12463). Suggested by Jörg Walter.
1019 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1021 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
1022 (print_load_command_name): Add case LC_DATA_IN_CODE.
1023 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
1025 2012-09-21 Glenn Morris <rgm@gnu.org>
1027 * eval.c (Frun_hook_with_args_until_success)
1028 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
1030 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
1032 * fileio.c (Ffile_selinux_context): Only call freecon when
1033 lgetfilecon succeeded.
1034 (Fset_file_selinux_context): Likewise. (Bug#12444)
1036 2012-09-21 Eli Zaretskii <eliz@gnu.org>
1038 * xdisp.c (try_window_reusing_current_matrix): Under bidi
1039 reordering, locate the cursor by calling set_cursor_from_row; if
1040 that fails, clear the desired glyph matrix before returning a
1041 failure indication to the caller. Fixes leaving garbled display
1042 when fast scrolling with a down-key. (Bug#12403)
1043 (compute_stop_pos_backwards): Fix a typo that caused crashes while
1044 scrolling through multibyte text.
1046 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
1048 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
1049 calling mark_vectorlike since that's the one that marks the window.
1050 (mark_discard_killed_buffers): Mark the final cdr.
1051 * window.h (struct window): Move prev/next_buffers to the
1052 non-standard fields.
1053 * window.c (make_window): Initialize prev/next_buffers manually.
1055 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
1057 Omit unused arg EXPECTED from socket hooks.
1058 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
1059 * nsterm.m (ns_term_init):
1060 * termhooks.h (struct terminal.read_socket_hook):
1061 * w32inevt.c (w32_console_read_socket):
1062 * w32term.c (w32_read_socket):
1063 * xterm.c (XTread_socket):
1064 Omit unused arg EXPECTED. All callers changed.
1065 (store_user_signal_events): Return void, not int, since callers no
1066 longer care about the return value. All uses changed.
1068 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
1070 * w32gui.h (XParseGeometry): Do not declare.
1072 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
1074 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
1075 Ignore 'expected'. See Eli Zaretskii in
1076 <http://bugs.gnu.org/12471#8> (last line).
1078 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
1079 (XParseGeometry): Now static. Substitute extremal values for
1080 values that are out of range.
1082 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
1084 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
1086 * nsfns.m (XParseGeometry): Remove.
1087 (Fx_create_frame): Call x_set_offset to correctly interpret
1088 top_pos in geometry.
1090 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
1091 (Fx_parse_geometry): If there is a space in string, call
1092 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
1094 2012-09-17 Eli Zaretskii <eliz@gnu.org>
1096 * search.c (scan_buffer): Use character positions in calls to
1097 region_cache_forward and region_cache_backward, not byte
1098 positions. (Bug#12196)
1100 * w32term.c (w32_read_socket): Set pending_signals to 1, like
1101 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
1103 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
1104 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
1105 emacs_blocked_malloc, now deleted.
1107 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
1109 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
1110 The workaround was for improving performance on Solaris 2.4, but
1111 is getting in the way now. Emacs will still work if someone is
1112 still running Solaris 2.4 in a museum somewhere; Sun dropped
1113 support for Solaris 2.4 in 2003.
1114 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
1115 * process.c (create_process) [HAVE_WORKING_VFORK]:
1116 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
1117 since Emacs no longer uses vfork on that platform.
1119 2012-09-17 Glenn Morris <rgm@gnu.org>
1121 * emacs.c: Use COPYRIGHT.
1123 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
1125 Remove configure's --without-sync-input option (Bug#12450).
1126 When auditing signal-handling in preparation for cleaning it up,
1127 I found that SYNC_INPUT has race conditions and would be a real
1128 pain to fix. Since it's an undocumented and deprecated
1129 configure-time option, now seems like a good time to remove it.
1130 Also see <http://bugs.gnu.org/11080#16>.
1131 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
1132 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
1133 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
1134 (malloc_hysteresis):
1135 (check_depth) [XMALLOC_OVERRUN_CHECK]:
1136 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
1137 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
1138 (dont_register_blocks, bytes_used_when_reconsidered)
1139 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
1140 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
1141 [!SYSTEM_MALLOC && !SYNC_INPUT]:
1142 Remove. All uses removed.
1143 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
1144 implementation, one that depends on whether the new macro
1145 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
1147 * atimer.c (run_timers, handle_alarm_signal):
1148 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
1149 (handle_async_input, process_pending_signals)
1150 (handle_input_available_signal, init_keyboard):
1151 * nsterm.m (ns_read_socket):
1152 * process.c (wait_reading_process_output):
1153 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
1154 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
1156 * xterm.c (XTread_socket):
1158 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
1159 * eval.c (handling_signal): Remove. All uses removed.
1160 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
1161 All uses replaced with the SYNC_INPUT version.
1162 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
1164 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1167 * font.c (Ffont_shape_gstring): Remove unused local.
1169 2012-09-16 Glenn Morris <rgm@gnu.org>
1171 * Makefile.in (clean): No longer run nextstep's clean.
1173 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
1175 (ns-app): Move here from ns.mk, and simplify.
1176 (clean): Simplify nextstep entry.
1177 * ns.mk: Remove file.
1179 2012-09-17 Kenichi Handa <handa@gnu.org>
1181 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
1182 not covert the last few charactes.
1184 2012-09-16 Kenichi Handa <handa@gnu.org>
1186 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
1187 here, but just check the validity of glyphs in the glyph-string.
1189 2012-09-16 Martin Rudalics <rudalics@gmx.at>
1191 * window.c (Fwindow_parameter, Fset_window_parameter):
1192 Accept any window as argument (Bug#12452).
1194 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
1196 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
1197 to ns_term_init to avoid memory leak.
1199 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
1200 explicit retain/release.
1201 (ns_term_init): Only allow one display. Initialize outerpool and
1204 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1206 Port _setjmp fix to POSIXish hosts as well as Microsoft.
1207 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
1208 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
1209 the Microsoft problem in a different way, by altering ../nt/config.nt.
1211 2012-09-15 Eli Zaretskii <eliz@gnu.org>
1226 * w16select.c: Remove inclusion of setjmp.h, as it is now included
1227 by lisp.h. This completes removal of setjmp.h inclusion
1228 erroneously announced in the previous commit. (Bug#12446)
1230 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
1233 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
1234 not defined as a macro. The latter happens on MS-Windows.
1237 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1239 Port better to POSIX hosts lacking _setjmp (Bug#12446).
1240 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
1241 Some instances of '#include <setjmp.h>' removed, if the
1242 only reason for the instance was because "lisp.h" was included.
1243 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
1244 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
1245 and _longjmp with the new symbols. Emacs already uses _setjmp if
1246 available, so this change affects only POSIXish hosts that have
1247 sigsetjmp but not _setjmp, such as some versions of Solaris and
1248 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
1249 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
1250 (png_load_body) [HAVE_PNG]:
1251 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
1252 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
1253 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
1254 since PNG requires jmp_buf. This is the only exception to the
1255 general rule that we now use sys_setjmp and sys_longjmp.
1256 This exception is OK since this code does not change the signal
1257 mask or longjmp out of a signal handler.
1259 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
1261 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
1262 Include "syssignal.h", for 'main_thread'.
1264 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
1266 Avoid out-of-range marker position (Bug#12426).
1267 * insdel.c (replace_range, replace_range_2):
1268 Adjust markers before overlays, as suggested by comments.
1269 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
1270 Remove redundant check before calling offset_intervals.
1272 2012-09-14 Martin Rudalics <rudalics@gmx.at>
1274 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
1275 current buffer (Bug#12387).
1277 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
1279 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
1281 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
1283 Use a more backwards-compatible timer format (Bug#12430).
1284 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
1285 vector element, not from the 4th, since PSECS is now at the end.
1286 (Fcurrent_idle_time): Doc fix.
1288 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
1290 Function to mark objects and remove killed buffers at once.
1291 * alloc.c (discard_killed_buffers): Rename to ...
1292 (mark_discard_killed buffers) ... new name. Add marking
1293 of remaining objects. Fix comment. Adjust users.
1294 (mark_object): Do not touch frame buffer lists here.
1295 * frame.c (delete_frame): Reset frame buffer lists here.
1297 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
1299 Better workaround for GNOME bug when --enable-gcc-warnings.
1300 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
1301 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
1302 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
1304 Simplify SIGIO usage (Bug#12408).
1305 The code that dealt with SIGIO was crufty and confusing, e.g., it
1306 played tricks like "#undef SIGIO" but these tricks were not used
1307 consistently. Simplify mostly by not #undeffing standard symbols,
1308 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
1309 or not as we please) rather than "defined SIGIO" (standard symbol
1310 that we probably shouldn't #undef).
1311 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
1312 Modules that need it can include it.
1313 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
1314 * dispextern.h (ignore_sigio): New decl.
1315 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
1316 unconditionally, since it's now a no-op if !USABLE_SIGIO.
1317 * emacs.c (shut_down_emacs):
1318 * keyboard.c (kbd_buffer_store_event_hold):
1319 Use ignore_sigio rather than invoking 'signal' directly.
1320 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
1322 (FIONREAD, SIGIO): Do not #undef.
1323 (tty_read_avail_input): Use #error rather than a syntax error.
1324 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
1325 for I_PIPE, used by SETUP_SLAVE_PTY.
1326 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
1327 * sysdep.c (croak): Remove; no longer needed. This bit of
1328 temporary code, with Fred N. Fish's comment that it's temporary,
1329 has been in Emacs since at least 1992!
1330 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
1331 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
1332 * syssignal.h (croak): Remove decl.
1333 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
1334 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
1335 now that we're termios-only.
1336 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
1337 * term.c (dissociate_if_controlling_tty): Use #error rather than
1340 Work around GCC and GNOME bugs when --enable-gcc-warnings.
1341 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
1342 to work around GNOME bug 683906.
1343 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
1344 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
1345 This works around GCC bug 54561.
1347 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
1349 More fixes for 'volatile' and setjmp/longjmp.
1350 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
1351 * image.c (struct png_load_context) [HAVE_PNG]: New type.
1352 (png_load_body) [HAVE_PNG]:
1353 (jpeg_load_body) [HAVE_JPEG]:
1354 New function, with most of the old parent function's body.
1355 (png_load) [HAVE_PNG]:
1356 (jpeg_load) [HAVE_JPEG]:
1357 Invoke the new function, to avoid longjmp munging our locals.
1358 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
1359 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
1360 longjmp is passed 2, as the C standard doesn't guarantee this.
1361 Instead, store the failure code into mgr->failure_code.
1363 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
1365 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
1366 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
1367 (syms_of_keyboard): Remove support for unread-command-char.
1369 2012-09-12 Eli Zaretskii <eliz@gnu.org>
1371 * w32proc.c (sys_kill): If PID is our process ID and the signal is
1372 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
1373 violation. (Bug#12426)
1375 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
1377 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
1379 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
1381 * eval.c: Add `inhibit-debugger'.
1382 (Qinhibit_debugger): New symbol.
1383 (call_debugger): Bind it instead of Qdebug_on_error.
1384 (maybe_call_debugger): Test Vinhibit_debugger.
1385 (syms_of_eval): Define inhibit-debugger.
1386 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
1387 (syms_of_xdisp): Remove inhibit-debug-on-message.
1389 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
1391 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
1392 If a nonvolatile local variable is written before a _longjmp to
1393 the frame containing the variable, and is read after the _longjmp,
1394 the value read is indeterminate. Some local variables of type
1395 'struct handler' and 'struct catchtag' are used in this way, so
1396 mark each of their slots as volatile if the slot can be set before
1397 _longjmp and read afterwards.
1398 * lisp.h (struct handler): var and chosen_clause are now volatile.
1399 (struct catchtag): val, next, and pdlcount are now volatile.
1401 * bidi.c (bidi_push_it, bidi_pop_it):
1402 * fns.c (copy_hash_table):
1403 * image.c (define_image_type):
1404 * keyboard.c (kbd_buffer_store_event_hold):
1405 * process.c (Fprocess_send_eof):
1406 * xfaces.c (x_create_gc) [HAVE_NS]:
1407 * xgselect.c (xg_select):
1408 Prefer assignment to memcpy when either will do.
1410 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
1411 Use pointer-to-a-pointer to simplify and avoid a NILP check each
1412 time an item is removed. No need to mark this function 'inline';
1413 the compiler knows better than we do.
1415 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
1417 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
1418 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
1419 to change_frame_size (Bug#12388).
1420 (windowDidResize:): Pass YES to updateFrameSize.
1422 * nsterm.h: Add delay parameter to updateFrameSize.
1424 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
1426 Discard killed buffers from deleted window and frame objects.
1427 This reduces an amount of references to killed buffers and
1428 helps GC to reclaim them faster.
1429 * alloc.c (discard_killed_buffers): New function.
1430 (mark_object): Use it for deleted windows and frames.
1431 (mark_object): If symbol's value is set up for a killed buffer
1432 or deleted frame, restore it's global binding.
1433 * data.c (swap_in_global_binding): Add GC notice.
1434 (swap_in_symval_forwarding): Use convenient set_blv_where.
1435 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
1436 * window.h: ... to here.
1438 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
1440 Convenient macro to check whether the buffer is live.
1441 * buffer.h (BUFFER_LIVE_P): New macro.
1442 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
1443 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
1445 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1447 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
1448 composition cases (Bug#12364).
1450 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
1451 overhang of succeeding glyphs overlapping box cursor.
1453 * w32term.c (x_draw_glyph_string): Likewise.
1455 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
1457 Simplify, document, and port floating-point (Bug#12381).
1458 The porting part of this patch fixes bugs on non-IEEE platforms
1459 with frexp, ldexp, logb.
1460 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
1462 * floatfns.c: Simplify discussion of functions that Emacs doesn't
1463 support, by removing commented-out code and briefly listing the
1464 C89 functions excluded. The commented-out stuff was confusing
1465 maintenance, e.g., we thought we needed cbrt but it was commented out.
1466 (logb): Remove decl; no longer needed.
1467 (isfinite): New macro, if not already supplied.
1468 (isnan): Don't replace any existing macro.
1469 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
1470 are present on all C89 platforms.
1471 (Ffrexp): Do not special-case zero, as frexp does the right thing
1473 (Flogb): Do not use logb, as it doesn't have the desired meaning
1474 on hosts that use non-base-2 floating point. Instead, stick with
1475 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
1476 frexp, to avoid getting an unspecified result.
1478 * xdisp.c (Qinhibit_debug_on_message): Now static.
1480 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
1482 * nsterm.m (ns_update_begin): Set clip path to whole view by using
1483 NSBezierPath (Bug#12131).
1485 2012-09-10 Chong Yidong <cyd@gnu.org>
1487 * fns.c (Fdelq, Fdelete): Doc fix.
1489 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
1491 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
1492 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
1494 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
1496 * lisp.h (make_lisp_ptr): New macro to replace XSET.
1497 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
1500 2012-09-09 Eli Zaretskii <eliz@gnu.org>
1502 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
1503 left fringe if the window has a left margin. This avoids leaving
1504 traces of the cursor because its leftmost pixel is not drawn over.
1506 * dispnew.c (update_window_line): When the left margin area of a
1507 screen line is updated, set the redraw_fringe_bitmaps_p flag of
1508 that screen line. (Bug#12277)
1510 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
1512 Assume C89 or later for math functions (Bug#12381).
1513 This simplifies the code, and makes it a bit smaller and faster,
1514 and (most important) makes it easier to clean up signal handling
1515 since we can stop worring about floating-point exceptions in
1516 library code. That was a problem before C89, but the problem
1517 went away many years ago on all practical Emacs targets.
1518 * data.c, image.c, lread.c, print.c:
1519 Don't include <math.h>; no longer needed.
1520 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
1521 might be autoconfigured, as that never happens.
1523 * doprnt.c (DBL_MAX_10_EXP):
1524 * print.c (DBL_DIG):
1525 Remove. C89 or later always defines these.
1526 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
1527 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
1528 (arith_error, domain_error, domain_error2):
1529 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
1530 no longer needed -- we simply return what C returns. All uses removed.
1531 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
1533 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
1534 Remove. All uses expanded, as these macros are no longer used
1535 more than once and are now more trouble than they're worth.
1536 (Ftan): Use tan, not sin / cos.
1537 (Flogb): Assume C89 frexp.
1538 (fmod_float): Assume C89 fmod.
1539 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
1540 (init_floatfns): Remove. All uses removed.
1542 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1544 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
1545 compositeToPoint for OSX < 10.6 (Bug#12390).
1547 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
1549 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
1550 This produces more-accurate results.
1552 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1554 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
1555 changes (Bug#12088).
1557 2012-09-08 Chong Yidong <cyd@gnu.org>
1559 * syntax.c (Fstring_to_syntax): Doc fix.
1561 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1563 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
1564 in the internal border.
1565 (x_set_window_size): Remove static variables and their usage.
1566 (ns_redraw_scroll_bars): Fix NSTRACE arg.
1567 (ns_after_update_window_line, ns_draw_fringe_bitmap):
1568 Remove fringe/internal border adjustment (Bug#11052).
1569 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
1570 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
1571 (ns_fix_rect_ibw): Remove.
1572 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
1573 (ns_dumpglyphs_box_or_relief): Ditto.
1574 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
1576 (ns_dumpglyphs_image): Ditto.
1577 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
1579 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
1580 their usage. Add fringe_extended_p and its use as in other terms.
1581 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
1582 scroll bar was removed.
1583 (updateFrameSize): New function.
1584 (windowDidResize): Move code to updateFrameSize and call it.
1586 * nsterm.h (EmacsView): Add updateFrameSize.
1588 2012-09-07 Chong Yidong <cyd@gnu.org>
1590 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
1592 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
1594 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1596 More signal-handler cleanup (Bug#12327).
1597 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
1598 Problem introduced when merging patches. Noted by Eli Zaretskii in
1599 <http://bugs.gnu.org/12327#67>.
1600 * floatfns.c: Comment fix.
1601 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
1602 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
1603 and anyway the declaration is harmless even if SIGDANGER is not defined.
1604 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
1605 defined BROKEN_FIONREAD). systty.h formerly did this, but other
1606 source files not surprisingly expected syssignal.h to define, or
1607 not define, SIGIO, and it's cleaner to do it that way, for consistency.
1608 Include <sys/ioctl.h>, for FIONREAD.
1609 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
1610 This eliminates a problem whereby other files mysteriously had
1611 to include "syssignal.h" before including "systty.h" if they
1612 wanted to use "#ifdef SIGIO".
1614 2012-09-07 Eli Zaretskii <eliz@gnu.org>
1616 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
1618 * w32.c (sigemptyset): Empty the set.
1619 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
1621 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
1623 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
1625 * alloc.c (mark_buffer): Revert unsafe marking optimization.
1626 (mark_object): Likewise for frame objects.
1628 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1630 * syssignal.h (handle_on_main_thread): Always declare,
1631 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
1632 This ports to platforms without HAVE_PTHREAD.
1634 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1636 Signal-handler cleanup (Bug#12327).
1637 Emacs's signal handlers were written in the old 4.2BSD style with
1638 sigblock and sigmask and so forth, and this led to some
1639 inefficiencies and confusion. Rewrite these to use
1640 pthread_sigmask etc. without copying signal sets around. Also,
1641 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
1642 'signal', and instead use functions that do not attempt to take
1643 over the system name space. This patch causes Emacs's text
1644 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
1645 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
1646 Do not include <signal.h> or "syssignal.h", as these
1647 modules do not use signals.
1648 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
1649 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
1650 Do not include <signal.h>, as "syssignal.h" does that for us now.
1651 * atimer.c (sigmask_atimers): New function.
1652 (block_atimers, unblock_atimers): New functions,
1653 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
1655 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
1656 no longer needed here.
1657 * emacs.c (main): Inspect existing signal handler with sigaction,
1658 so that there's no need to block and unblock SIGHUP.
1659 * sysdep.c (struct save_signal): New member 'action', replacing
1660 old member 'handler'.
1661 (save_signal_handlers, restore_signal_handlers):
1662 Use sigaction instead of 'signal' to save and restore.
1663 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
1664 New function. All users of 'signal' modified to use set_sighandler
1665 if they're writeonly, and to use sys_signal if they're read+write.
1666 (emacs_sigaction_init, forwarded_signal): New functions.
1667 (sys_signal): Remove. All uses replaced by calls to sigaction
1668 and emacs_sigaction_init, or by direct calls to 'signal'.
1669 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
1670 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
1671 all uses replaced by pthread_sigmask etc. calls.
1672 * syssignal.h: Include <signal.h>.
1673 (emacs_sigaction_init, forwarded_signal): New decls.
1674 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
1675 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
1676 (sigmask, sys_sigmask): Remove; no longer needed.
1677 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
1678 (sigblock, sigunblock, sigfree):
1679 (sigsetmask) [!defined sigsetmask]:
1680 Remove. All uses replaced by pthread_sigmask.
1681 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
1682 no longer need to be replaced, and its typical old uses
1683 are now done via emacs_sigaction_init and sigaction.
1684 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
1685 (sys_sigdel): Remove; unused.
1686 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
1688 2012-09-06 Eli Zaretskii <eliz@gnu.org>
1690 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
1691 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
1693 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1695 Explicitly mark buffer_defaults and buffer_local_symbols.
1696 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
1697 mark_local_symbols here.
1698 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
1699 since special buffers aren't marked here any more.
1700 (allocate_buffer): Chain new buffer with all_buffers here...
1701 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
1703 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
1704 (syms_of_buffer): Remove staticpro of the above.
1705 (init_buffer_once): Set names for buffer_defaults and
1706 buffer_local_symbols.
1708 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1710 Use bool for booleans in font-related modules.
1711 * font.c (font_intern_prop, font_style_to_value)

1713 (generate_otf_features, font_check_otf_features, font_check_otf)
1714 (font_match_p, font_list_entities, font_at):
1715 * fontset.c (fontset_id_valid_p, reorder_font_vector
1716 (fontset_find_font, Fset_fontset_font)
1717 (face_suitable_for_char_p) [0]:
1718 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
1719 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
1720 (m17n_flt_initialized, ftfont_shape_by_flt):
1721 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
1722 * nsfont.m (nsfont_draw):
1723 * w32font.c (w32font_draw):
1724 * w32term.c (x_draw_glyphless_glyph_string_foreground):
1725 Use bool for booleans.
1726 * font.h: Adjust to above API changes.
1727 (struct font, struct font_driver, struct font_driver_list):
1728 Use bool for booleans.
1729 (struct font): Remove useless member encoding_type.
1731 * fontset.c, xftfont.c: Omit unnecessary static decls.
1733 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1735 * alloc.c (mark_object): Revert window marking code
1736 since it's unsafe for the Fset_window_configuration.
1738 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1740 Fix race conditions with signal handlers and errno (Bug#12327).
1741 Be more systematic about preserving errno whenever a signal
1742 handler returns, even if it's not in the main thread. Do this by
1743 renaming signal handlers to distinguish between signal delivery
1744 and signal handling. All uses changed.
1745 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
1746 * data.c (deliver_arith_signal): Rename from arith_error.
1747 * dispnew.c (deliver_window_change_signal): Rename from
1748 window_change_signal.
1749 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
1750 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
1751 * keyboard.c (deliver_input_available_signal): Rename from
1752 input_available_signal.
1753 (deliver_user_signal): Rename from handle_user_signal.
1754 (deliver_interrupt_signal): Rename from interrupt_signal.
1755 * process.c (deliver_pipe_signal): Rename from send_process_trap.
1756 (deliver_child_signal): Rename from sigchld_handler.
1757 * atimer.c (handle_alarm_signal):
1758 * data.c (handle_arith_signal):
1759 * dispnew.c (handle_window_change_signal):
1760 * emacs.c (handle_fatal_signal, handle_danger_signal):
1761 * keyboard.c (handle_input_available_signal):
1762 * keyboard.c (handle_user_signal, handle_interrupt_signal):
1763 * process.c (handle_pipe_signal, handle_child_signal):
1764 New functions, with the actual signal-handling code taken from the
1765 original respective signal handlers, sans the sporadic attempts to
1766 preserve errno, since that's now done by handle_on_main_thread.
1767 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
1768 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
1769 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1771 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1772 Move initialization of main_thread to sysdep.c's init_signals.
1773 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
1774 our usage, and simplifies the mainline code.
1775 (record_child_status_change): New static function, as a helper
1776 for handle_child_signal, and with most of the old child handler's
1778 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
1779 (handle_child_signal): Use the above.
1780 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1781 Moved here from emacs.c.
1782 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
1783 code moved here from emacs.c's main function.
1784 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
1785 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
1786 This lets callers save and restore errno properly.
1788 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1790 Remove redundant or unused things here and there.
1791 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
1792 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
1793 * editfns.c (Fcompare_buffer_substrings): Likewise.
1794 * frame.h (struct terminal, struct font_driver_list):
1795 Remove redundant declarations.
1796 * window.h (Qleft, Qright): Likewise.
1798 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1800 Do not mark objects from deleted buffers, windows and frames.
1801 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
1802 (mark_object): Likewise for windows and frames.
1804 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1806 * alloc.c (valid_lisp_object_p): Treat killed buffers,
1807 buffer_defaults and buffer_local_symbols as valid objects.
1808 Return special value to denote them.
1810 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1812 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
1813 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)

1825 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)

1827 * lisp.h (struct Lisp_Hash_Table.cmpfn):
1828 * window.c (compare_window_configurations):
1829 Use bool for booleans.
1830 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
1831 (Fdefault_file_modes): Now mode_t, not int, for modes.
1832 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
1833 (internal_delete_file): Now returns void, not a (boolean) int,
1834 since nobody was looking at the return value.
1835 * lisp.h, window.h: Adjust to above API changes.
1837 * xdisp.c (set_message): Simplify and reindent last change.
1839 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
1841 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
1843 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
1845 * eval.c (call_debugger): Make the function non-static so that we
1846 can call it from set_message.
1848 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
1849 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
1851 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1853 Give more-useful info on a fatal error (Bug#12328).
1854 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
1855 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
1856 of doing the work ourselves.
1857 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
1858 do most of the work.
1859 (fatal_error_backtrace): New function, taken from the guts
1860 of the old fatal_error_signal, but with a new option to output
1862 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
1863 info about the signal than just its number.
1864 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
1865 * sysdep.c: Include <execinfo.h>
1866 (emacs_backtrace): New function, taken partly from the previous
1867 code of the 'die' function.
1868 (emacs_abort): Call fatal_error_backtrace rather than abort.
1870 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
1872 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
1873 eager (load-time) macro-expansion.
1874 * lisp.mk (lisp): Add macroexp.
1876 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1878 Simplify redefinition of 'abort' (Bug#12316).
1879 Do not try to redefine the 'abort' function. Instead, redo
1880 the code so that it calls 'emacs_abort' rather than 'abort'.
1881 This removes the need for the NO_ABORT configure-time macro
1882 and makes it easier to change the abort code to do a backtrace.
1883 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
1884 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
1885 Remove; sysdep.c's emacs_abort now takes its place.
1886 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
1887 'abort' changed to use 'emacs_abort'.
1888 * msdos.c (dos_abort) [defined abort]: Remove; not used.
1889 (abort) [!defined abort]: Rename to ...
1890 (emacs_abort): ... new name.
1891 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
1892 the place of the old 'abort' in emacs.c.
1893 * w32.c, w32fns.c (abort): Do not #undef.
1894 * w32.c (emacs_abort): Rename from w32_abort.
1896 2012-09-04 Eli Zaretskii <eliz@gnu.org>
1898 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
1899 offsets[j].dv, since the y axis of the screen coordinates points
1900 down, while the y axis of the font definition coordinates points
1901 up. This fixes display of Arabic diacritics such as KASRA and
1902 KASRATAN. (Bug#11860)
1904 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1906 Be more systematic about _setjmp vs setjmp.
1907 * alloc.c (test_setjmp, mark_stack):
1908 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
1909 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
1910 (png_load, my_error_exit, jpeg_load):
1911 * process.c (send_process_trap, send_process):
1912 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
1913 The underscored versions are up to 30x faster on some hosts.
1914 Formerly, the code used setjmp+longjmp sometimes and
1915 _setjmp+_longjmp at other times, with no particular reason to
1916 prefer setjmp+longjmp.
1918 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
1920 Fix minor problem found by static checking.
1921 * buffer.c (Fdelete_all_overlays): Return nil.
1923 2012-09-03 Martin Rudalics <rudalics@gmx.at>
1925 * buffer.c (Fdelete_all_overlays): New function.
1927 2012-09-03 Chong Yidong <cyd@gnu.org>
1929 * gtkutil.c: Add extern decl for Qxft.
1931 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

1945 All callers changed.
1946 * eval.c (interactive_p): Omit always-true boolean argument
1947 EXCLUDE_SUBRS_P. All callers changed.
1948 * dispextern.h, lisp.h: Reflect above API changes.
1949 * firstfile.c (dummy): Use the address of 'main', whose signature
1950 won't change, instead of the address of 'initialize', whose
1951 signature just changed from int to bool.
1952 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
1953 * msdos.c (fatal_error_in_progress): ... from here.
1954 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
1956 (redisplay_internal, unwind_redisplay): Simply clear
1957 REDISPLAYING_P when unwinding, instead of saving its previous,
1958 always-false value and then restoring it.
1960 Clean up some extern decls.
1961 Mostly, this hoists extern decls out of .c files and into .h files.
1962 That way, we're more likely to catch errors if the interfaces change.
1963 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
1964 declare xg_mark_data.
1965 * dispextern.h (x_frame_parm_handlers):

1985 Remove now-redundant extern decls.
1986 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
1987 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
1989 * xfaces.c: Remove unnecessary static decls.
1990 * xterm.c (updating_frame): Remove decl of nonexistent object.
1992 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
1993 when building globals.h, as the objects that are not built on
1994 this host are not needed to compile C files on this host.
1996 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
1998 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

2046 2012-09-01 Eli Zaretskii <eliz@gnu.org>
2048 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
2049 more than one grapheme cluster passed to the shaper: compute the
2050 offset adjustment values separately for each cluster. (Bug#11860)
2052 * image.c: Restore mistakenly removed inclusion of w32.h. Without
2053 it, GCC doesn't see prototypes of w32_delayed_load, and complains
2054 about implicit conversions from integer to pointer.
2056 2012-09-01 Daniel Colascione <dancol@dancol.org>
2058 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
2059 system used too early.
2061 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
2063 Better seed support for (random).

2112 window system declarations.
2114 * frame.h: Move common functions here: set_frame_menubar,
2115 x_set_window_size, x_sync, x_get_focus_frame,
2116 x_set_mouse_position, x_set_mouse_pixel_position,
2117 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

2141 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
2143 Remove mark_ttys function and fix tty_display_info initialization.
2144 * lisp.h (mark_ttys): Remove prototype.
2145 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
2146 to mark_ttys because all possible values of 'top_frame' slot are
2147 the frames which are reachable from Vframe_list.
2148 * term.c (mark_ttys): Remove.
2149 (init_tty): Safely initialize 'top_frame' slot with Qnil.
2151 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>

2157 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
2158 bitfields from unsigned char to unsigned.

2173 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
2174 for GCC 4.7.1 x86-64.
2176 2012-08-30 Glenn Morris <rgm@gnu.org>
2178 * lread.c (init_lread): For out-of-tree builds, only add the
2179 source directory's site-lisp dir to the load-path if it exists,
2180 consistent with in-tree builds. (Bug#12302)
2182 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
2184 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

2193 (addString:row:): Remove return self, declare return value as void.
2194 (addSplit): Remove return self, declare return value as void.
2195 (clicked:): Remove return self, declare return value as void.
2196 Set dialog_return to button_values[seltag]. Code formatting change.

2198 Code formatting change.
2199 (timeout_handler:): Set timer_fired to YES.
2200 (runDialogAt:): Set timer_fired to NO.
2201 Handle click on close button as quit.
2203 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
2204 Add window_closed and button_values. Add void as return value for
2205 add(Button|String|Split). addButton takes int instead of Lisp_Object.
2206 Add process_dialog as new member.
2208 2012-08-28 Eli Zaretskii <eliz@gnu.org>
2210 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

2271 (change_frame_size_1, sit_for):
2272 Use bool for boolean.
2273 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
2274 and remove last int (actually boolean) argument, which was always 0.
2275 All callers changed.
2276 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
2277 * dispextern.h (struct composition_it): Use bool for boolean.
2278 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
2279 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
2280 * dired.c (file_name_completion):
2281 Use bool for boolean. (This was missed in an earlier change.)
2283 2012-08-27 Martin Rudalics <rudalics@gmx.at>
2285 * window.c (Fset_window_configuration): Revert first part of
2288 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
2290 * nsterm.h (NSPanel): New class variable dialog_return.
2292 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
2293 Initialize dialog_return.
2294 (windowShouldClose:): Use stop instead of stopModalWithCode.
2295 (clicked:): Ditto, and also set dialog_return (Bug#12258).
2296 (timeout_handler:): Use stop instead of abortModal. Send a dummy
2298 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
2301 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>
2303 * composite.c, data.c, dbusbind.c, dired.c: Use bool for booleans.

2313 Use bool for booleans.
2314 * dired.c (file_name_completion):
2315 * process.h (fd_callback):
2316 Omit int (actually boolean) argument. It wasn't being used.
2318 * composite.h, lisp.h: Reflect above API changes.

2342 * fileio.c (Finsert_file_contents):
2343 Use bool for booleans.
2344 * coding.h, lisp.h: Reflect above API changes.
2345 * coding.c: Remove unnecessary static function decls.
2346 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
2347 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
2348 not a boolean 'int', since callers never look at the return value.
2349 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
2350 * coding.h (decoding_buffer_size, encoding_buffer_size)
2351 (emacs_mule_string_char): Remove unused extern decls.
2352 (struct iso_2022_spec, struct coding_system):
2353 Use 'unsigned int : 1' for boolean fields, since there's more than one.
2354 (struct emacs_mule_spec): Remove unused field 'full_support'.
2355 All initializations removed.
2356 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
2358 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
2360 Fix spare memory change (Bug#12286).
2361 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
2362 (valid_lisp_object_p): Likewise.
2364 2012-08-27 Martin Rudalics <rudalics@gmx.at>
2366 * window.c (Fset_window_configuration): Record any window's old
2367 buffer if it's replaced (see Bug#8789). If the new current
2368 buffer doesn't appear in the selected window, go to its old
2371 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
2373 Special MEM_TYPE_SPARE to denote reserved memory.
2374 * alloc.c (enum mem_type): New memory type.
2375 (refill_memory_reserve): Use new type for spare memory.
2376 This prevents live_cons_p and live_string_p from incorrect
2377 detection of uninitialized objects from spare memory as live.
2379 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
2382 * Makefile.in (.PHONY): versioclean -> versionclean.
2384 Remove unused external symbols.
2385 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
2386 * window.c (Qwindow_valid_p, decode_valid_window):
2387 Now static, not extern.
2388 * data.c (Qinterval): Remove; unused.
2389 (syms_of_data): Do not define 'interval'.
2390 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
2391 * window.h (decode_valid_window):
2394 * character.c, charset.c, chartab.c: Use bool for booleans.
2395 * character.c (lisp_string_width, string_count_byte8)

2404 (char_table_set_range, optimize_sub_char_table)
2405 (map_sub_char_table):
2406 Use bool for boolean.
2407 * character.c (str_to_unibyte): Omit last boolean argument; it was
2408 always 0. All callers changed.
2409 * character.h, charset.h: Adjust to match previous changes.
2410 * character.h (char_printable_p): Remove decl of nonexistent function.
2411 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
2412 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
2413 are all boolean, so make them single-bit bitfields.
2415 * lisp.h (ASET): Remove attempt to detect side effects.
2416 It was meant to be temporary and it often doesn't work,
2417 because when IDX has side effects the behavior of IDX==IDX
2418 is undefined. See Stefan Monnier in
2419 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
2421 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
2423 * lisp.h (functionp): New function (extracted from Ffunctionp).
2424 (FUNCTIONP): Use it.
2425 * eval.c (Ffunctionp): Use it.
2427 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
2429 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
2430 as that's faster and simpler than static storage. Don't bother
2431 with the g_main_context_query overhead if g_main_context_pending
2432 says no events are pending.
2433 (gfds, gfds_size): Remove these static vars.
2434 (xgselect_initialize): Remove; no longer needed.
2435 All uses and decls removed.
2437 * emacs.c (fatal_error_signal_hook): Remove.
2438 All uses removed. This leftover from old code was always 0.
2440 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
2441 * casefiddle.c (casify_object, casify_region):
2442 * casetab.c (set_case_table):
2443 * category.c, category.h (word_boundary_p):
2444 * category.h (CHAR_HAS_CATEGORY):
2445 Use bool for booleans, instead of int.
2447 2012-08-25 Eli Zaretskii <eliz@gnu.org>
2449 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
2451 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
2453 On assertion failure, print backtrace if available.
2454 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
2455 (die) [ENABLE_CHECKING]: Print a backtrace if available.
2456 * Makefile.in (LIB_EXECINFO): New macro.
2459 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
2460 * bytecode.c (exec_byte_code):
2461 * callint.c (check_mark, Fcall_interactively):
2462 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
2463 (getenv_internal, sync_process_alive, call_process_exited):
2464 * lisp.h (USE_SAFE_ALLOCA):
2465 Use bool for booleans, instead of int.
2466 * lisp.h, process.h: Adjust prototypes to match above changes.
2467 * callint.c (Fcall_interactively): Don't assume the mark's
2468 offset fits in 'int'.
2470 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
2472 * buffer.c, buffer.h: Use bool for boolean.
2473 * buffer.c (reset_buffer_local_variables)
2474 (buffer_lisp_local_variables, Fset_buffer_modified_p)
2475 (Frestore_buffer_modified_p, Fset_buffer_multibyte):

2477 (overlay_touches_p, overlay_strings, Foverlay_put)
2478 (report_overlay_modification, call_overlay_mod_hooks):
2479 (mmap_enlarge, mmap_set_vars):
2480 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
2481 Use bool for booleans, instead of int.
2482 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
2483 since the 1-or-0 return value is always ignored anyway.
2484 (mmap_initialized_p):
2485 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
2486 * buffer.h, lisp.h: Adjust prototypes to match above changes.
2488 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
2490 * bidi.c: Use bool for boolean.
2491 This is a bit more readable, and makes the text segment of bidi.o
2492 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
2493 Presumably it's faster too.
2494 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
2496 (bidi_cache_find_level_change, bidi_cache_iterator_state)
2497 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
2498 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
2499 (bidi_explicit_dir_char, bidi_level_of_next_char)
2500 (bidi_find_other_level_edge, bidi_move_to_visually_next):
2501 Use bool for booleans, instead of int.
2502 * dispextern.h (bidi_init_it, bidi_paragraph_init)
2503 (bidi_unshelve_cache): Adjust decls to match code.
2505 2012-08-23 Martin Rudalics <rudalics@gmx.at>
2507 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
2510 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
2512 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
2513 * atimer.h: Include <stdbool.h>.
2515 2012-08-22 Dan Nicolaescu <dann@gnu.org>
2517 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
2518 compile time tests instead of run time tests on systems that do
2520 (FRAME_MAC_P): Remove leftover from deleted code.
2521 * frame.c (syms_of_frame): Remove leftover from deleted code.
2523 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
2525 * nsterm.m (insertText:): Don't clear modifiers if code is space.
2527 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
2529 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
2530 Otherwise, the compiler complains about (A?B:C) where B is void
2531 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
2532 (fontset_add): Return void, for FONTSET_ADD.
2534 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2536 * alloc.c: Use bool for booleans.
2537 (gc_in_progress, abort_on_gc)
2538 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
2539 (dont_register_blocks) [GC_MALLOC_CHECK]:
2540 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
2541 (check_string_bytes, make_specified_string, memory_full)
2542 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
2543 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
2544 (mark_stack, valid_pointer_p, make_pure_string)
2545 (Fgarbage_collect, survives_gc_p, gc_sweep):
2546 Use bool for booleans, instead of int.
2547 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
2548 Remove unused local.
2549 * alloc.c (PURE_POINTER_P):
2550 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
2551 * editfns.c (Fformat):
2552 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
2554 * fns.c (sweep_weak_table):
2555 * lisp.h (suppress_checking, push_message, survives_gc_p)
2556 (make_pure_string, gc_in_progress, abort_on_gc):
2557 * lread.c (readchar, read1):
2558 * print.c (Fprin1_to_string):
2559 * xdisp.c (push_message):
2560 Use bool for booleans affected directly or indirectly by
2563 Make recently-introduced setters macros.
2564 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
2565 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
2566 (set_fontset_default, set_fontset_fallback): Rename from their
2567 upper-case counterparts, and make them functions rather than macros.
2568 This is more consistent with the other recently-introduced setters.
2569 These don't need to be inline, since they're local.
2571 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
2573 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
2574 the loop (Bug#12247).
2576 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2578 * lisp.h (vcopy): Use memcpy rather than our own loop.
2579 This fixes a performance regression introduced by the recent
2580 addition of vcopy. This means 'vcopy' will need to be modified
2581 for a copying collector, but that's OK. Also, tighten the
2582 checking in the assertion.
2584 2012-08-21 Eli Zaretskii <eliz@gnu.org>
2586 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
2587 components for RTL text (Bug#11860). Adjust X-OFFSET of each
2588 non-base glyph for the width of the base character, according to
2589 what x_draw_composite_glyph_string_foreground expects.
2590 Generate WADJUST value according to composition_gstring_width's
2591 expectations, to produce correct width of the composed character.
2592 Reverse the sign of the DU offset produced by ScriptPlace.
2594 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2596 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
2598 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2600 Avoid direct writes to contents member of struct Lisp_Vector.
2601 * lisp.h (vcopy): New function to copy data into vector.
2602 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
2603 * fns.c (Ffillarray): Use ASET.
2604 * keyboard.c (timer_check_2): Use AREF and ASET.
2605 (append_tool_bar_item, Frecent_keys): Use vcopy.
2606 * lread.c (read_vector): Use ASET.
2607 * msdos.c (Frecent_doskeys): Use vcopy.
2608 * xface.c (Finternal_copy_lisp_face): Use vcopy.
2609 (Finternal_merge_in_global_face): Use ASET and vcopy.
2610 * xfont.c (xfont_list_pattern): Likewise.
2612 2012-08-21 Martin Rudalics <rudalics@gmx.at>
2614 * window.c (Fwindow_point): For the selected window always return
2615 the position of its buffer's point.
2616 (Fset_window_point): For the selected window always go in its
2617 buffer to the specified position.
2619 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2621 Setter macros for fontsets.
2622 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
2623 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
2624 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
2627 2012-08-20 Glenn Morris <rgm@gnu.org>
2629 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
2630 Don't assume that `ln -f' works.
2632 2012-08-20 Eli Zaretskii <eliz@gnu.org>
2634 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
2635 and later about non-assignments with no effect. See discussion at
2636 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
2639 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2641 Inline setter functions for Lisp_Objects slots of struct specbinding.
2642 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
2645 2012-08-20 Martin Rudalics <rudalics@gmx.at>
2647 * window.c (select_window): Always make selected window's buffer
2650 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2652 Use AREF and ASET for docstrings of category tables.
2653 * category.h (CATEGORY_DOCSTRING): Use AREF.
2654 (SET_CATEGORY_DOCSTRING): Use ASET.
2655 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
2657 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2659 Inline setter functions for hash table members.
2660 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
2661 (set_hash_hash, set_hash_index): Rename with _slot suffix.
2662 (set_hash_key_and_value, set_hash_index, set_hash_next)
2663 (set_hash_hash): New functions.
2664 * charset.c, fns.c: Adjust users.
2666 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2668 Inline getter and setter functions for per-buffer values.
2669 * buffer.h (per_buffer_default, set_per_buffer_default)
2670 (per_buffer_value, set_per_buffer_value): New functions.
2671 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
2672 * buffer.c, data.c: Adjust users.
2674 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
2676 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
2678 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
2680 Rely on <config.h> + <unistd.h> to declare 'environ',
2681 as gnulib does this if the system doesn't.
2682 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
2683 Remove declaration. MS-Windows declares it on stdlib.h which is
2684 included by conf_post.h.
2685 * emacs.c (environ) [DOUG_LEA_MALLOC]:
2686 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
2687 * vm-limit.c: Include <unistd.h>, for 'environ'.
2689 * unexaix.c, unexcoff.c: Include "mem-limits.h".
2690 (start_of_data): Remove decl; mem-limits.h provides it.
2692 * xdisp.c (handle_invisible_prop): Make it a bit faster
2693 and avoid a gcc -Wmaybe-uninitialized diagnostic.
2695 2012-08-19 Chong Yidong <cyd@gnu.org>
2697 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
2700 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
2702 * .gdbinit: Use call instead of set when calling a function in the

3106 Use bool, not int, for Lisp booleans.
3107 This is more natural, and on my platform (GCC 4.7.1 x86-64) it

3110 (struct Lisp_Boolfwd, defvar_bool):
3111 * lread.c (defvar_bool): Use bool, not int, for Lisp booleans.

3572 installation tree, as appropriate.
3574 * callproc.c (init_callproc_1): Call decode_env_path instead of
3575 doing its equivalent by hand.
3576 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
3577 the code that sets Vexec_path run on MS-Windows.
3579 * lread.c (init_lread): Add comments to #ifdef's.
3581 * msdos.c (dos_set_window_size, IT_update_begin)
3582 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
3583 instead of direct references.
3585 2012-08-04 Paul Eggert <eggert@cs.ucla.edu>
3587 Export DEFAULT_REHASH_* to GDB.
3588 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
3589 Now constants, not macros.
3591 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
3593 Remove unnecessary casts involving pointers.
3594 These casts are no longer needed now that we assume C89 or later,
3595 since they involve casting to or from void *.
3596 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
3597 (make_pure_float, make_pure_vector):
3598 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

3607 (x_get_window_property, x_get_window_property_as_lisp_data):
3608 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
3609 Remove unnecessary pointer casts.
3610 * alloc.c (record_xmalloc): New function.
3611 * lisp.h (record_xmalloc): New decl.
3612 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
3613 more like a function. This is because the pointer cast is not
3614 needed. All uses changed.
3615 * print.c (print_string, print_error_message): Avoid length recalc.
3617 Improve fix for macroexp crash with debugging (Bug#12118).
3618 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
3619 ARRAY_MARK_FLAG when checking subscripts, because ASET is
3620 not supposed to be invoked from the garbage collector.
3621 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
3622 (gc_aset): New function, which is like ASET but can be
3623 used in the garbage collector.
3624 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
3625 (set_hash_index): Use it instead of ASET.

3637 (map_w32_filename): Improve commentary. Simplify switch.
3638 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
3639 headers (most versions of MinGW w32api don't).
3640 (get_security_info, create_symbolic_link)
3641 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
3643 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
3644 in the argument file name.

3646 GetFileAttributes fails with network-related error codes.
3647 (sys_rename): Diagnose renaming of a symlink when the user doesn't
3648 have the required privileges.
3649 (get_file_security_desc_by_name): Rename from
3650 get_file_security_desc.
3651 (stat_worker): New function, with most of the guts of 'stat', and
3652 with addition of handling of symlinks and support for 'lstat'.
3653 If possible, get file's attributes and security information by
3654 handle, not by name. Produce S_IFLNK bit for symlinks, when
3655 called from 'lstat'.
3656 (stat, lstat): New functions, call 'stat_worker'.
3657 (symlink, readlink, careadlinkat): Rewritten to create and resolve
3658 symlinks when the underlying filesystem supports them.
3660 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
3662 Fix macroexp crash on Windows with debugging (Bug#12118).
3663 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
3664 checking subscripts; problem introduced with the recent
3665 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
3666 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
3667 since it's used in non-static inline functions now.
3669 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
3670 Don't assume buffer size fits in 'int'. Remove unused local.
3672 Use C99-style 'extern inline' if available.

3684 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
3685 * alloc.c (LISP_INLINE):
3686 * buffer.c (BUFFER_INLINE):
3687 * category.c (CATEGORY_INLINE):
3688 * character.c (CHARACTER_INLINE):
3689 * charset.c (CHARSET_INLINE):
3690 * composite.c (COMPOSITE_INLINE):
3691 * dispnew.c (DISPEXTERN_INLINE):
3692 * sysdep.c (SYSTIME_INLINE):
3693 Define to EXTERN_INLINE, so that the corresponding functions
3694 are compiled into code.
3695 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
3696 (INLINE_HEADER_END): New macros.
3697 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

3717 hard-coding the path separator.
3719 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
3721 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
3722 This how ASET and AREF are supposed to work, and makes
3723 it easier to think about future improvements. See
3724 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
3725 * charset.h (set_charset_attr): New function.
3726 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
3727 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

4107 (w32_kbd_patch_key, key_event): Use the codepage returned by
4108 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

4140 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
4141 enumeration constants, as PURE and HEAP are too general, and clash
4142 with other headers and sources, such as gmalloc.c and the
4143 MS-Windows system headers. All users changed.
4145 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
4147 Revert last save_excursion_save and save_excursion_restore changes.
4148 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

4161 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
4162 arms of an 'if', not using conditional expressions; otherwise GDB
4163 complains about the types in the unevaluated arm when the argument
4164 is an integer literal.
4165 (xgetint): Simplify expression.
4166 * alloc.c (gdb_make_enums_visible): New constant. This ports to
4167 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
4168 Zaretskii in <http://bugs.gnu.org/12036#13>.
4169 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
4170 needed now that we have gdb_make_enums_visible.
4171 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
4172 (enum enum_USE_LSB_TAG):
4173 New enum types, packaging up enums that need to be exported to GDB.

4215 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
4216 emacs.c, as this is a more-suitable home. Had this been done earlier
4217 the fix for 12036 would have avoided some of the problems noted in
4218 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
4219 would have been more obvious.
4220 * emacs.c: Do not include <verify.h>; no longer needed.
4221 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
4222 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
4223 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

4229 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
4230 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
4231 not be usable in #if. This simplifies things.
4233 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
4235 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

4240 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
4241 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
4242 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
4243 Adjust to changes in lisp.h and emacs.c, by using
4244 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
4245 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
4246 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
4247 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
4248 instead of gdb_valbits.
4249 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
4250 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
4251 instead of gdb_array_mark_flag.
4252 (xboolvector): Get size from $->size, not $->header.size.
4253 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
4254 (xreload, hook-run, hookpost-run): Remove.
4255 * emacs.c: Include <verify.h>.
4256 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
4257 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
4259 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
4260 (gdb_USE_LSB_TAG): New enum constants.
4261 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
4262 Also define these as enum constants, so they're visible to GDB.
4263 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
4264 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
4265 as constants, so they're visible to GDB.

4268 Now enum constants, not macros, so they're visible to GDB.
4269 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
4270 more convenient now. All uses changed.
4271 (VALMASK) [USE_LSB_TAG]: Also define in this case.
4272 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
4274 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

4281 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
4282 add argument, tune behavior, and adjust all callers.
4284 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
4286 Use typedef for EMACS_INT, EMACS_UINT.
4287 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
4288 than macros. This simplifies debugging in the usual case, since
4289 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
4290 and it allows expressions involving EMACS_INT casts.
4291 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
4293 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

4303 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
4305 Adjust buffer text indirection counters at the end of Fkill_buffer.
4306 * buffer.c (Fkill_buffer): Adjust indirection counters when the
4307 buffer is definitely dead. This should really fix an issue reported
4308 by Christoph Scholtes again. (Bug#12007).
4309 (init_buffer_once): Initialize indirection counters of
4310 buffer_defaults and buffer_local_symbols (for sanity and safety).
4312 2012-07-24 Eli Zaretskii <eliz@gnu.org>
4314 * xdisp.c (init_iterator): Don't compute dimensions of truncation
4315 and continuation glyphs on tooltip frames, leave them at zero.

4343 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
4345 Swap buffer text indirection counters in Fbuffer_swap_text.
4346 * buffer.c (Fbuffer_swap_text): Swap indirections too.
4347 This avoids crash reported by Christoph Scholtes at
4348 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
4350 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
4352 * nsmenu.m (Popdown_data): New struct.
4353 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
4355 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
4356 (initWithContentRect): Make imgView and contentView non-static
4357 and autorelease them. Also autorelease img and matrix (Bug#12005).
4358 (dealloc): Remove (Bug#12005).
4360 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
4362 Adjust consing_since_gc when objects are explicitly freed.

4375 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
4377 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
4378 as it's limited by the amount of memory, not by INT_MAX.
4380 2012-07-21 Eli Zaretskii <eliz@gnu.org>
4382 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
4383 in special-event-map. See the discussion at

4442 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
4443 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
4444 Adjust users accordingly.

4926 used in the window. Move the code that appends a stretch glyph to
4927 produce_special_glyphs, so that it could be used for truncation
4928 and continuation glyphs alike.
4929 (produce_special_glyphs) [HAVE_WINDOW_SYSTEM]: Produce a stretch
4930 glyph of a suitably computed width, to align the special glyphs at
4931 the window margin. Code moved from display_line. (Bug#11832)

5106 * s/aix4-2.h (unix): Remove; no longer needed.
5108 EMACS_TIME simplification (Bug#11875).
5109 This replaces macros (which typically do not work in GDB)
5110 with functions, typedefs and enums, making the code easier to debug.
5111 The functional style also makes code easier to read and maintain.
5112 * systime.h: Include <sys/time.h> on all hosts, not just if
5113 WINDOWSNT, since 'struct timeval' is needed in general.

5123 which are not functions. All uses rewritten to use:
5124 (make_emacs_time): New function.

5126 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
5127 not functions. All uses rewritten to use the following, respectively:
5128 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
5129 (add_emacs_time, sub_emacs_time): New functions.
5130 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

5153 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
5154 Prefer snprintf to strncpy.
5155 * nsterm.m (ns_term_init):
5156 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
5157 * nsterm.m (ns_term_init):
5158 Avoid the need for strncpy, by using build_string or
5159 make_unibyte_string directly. Use dtoastr, not snprintf.
5160 * process.c (Fmake_network_process): Diagnose service names that
5161 are too long, rather than silently truncating them or creating
5162 non-null-terminated names.
5163 (Fnetwork_interface_info): Likewise, for interface names.
5164 * sysdep.c (system_process_attributes) [GNU_LINUX]:
5165 Prefer sprintf to strncat.

5172 Clarify fallback case.
5174 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

5179 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
5180 where argument type is known to be a Lisp_Cons.

5197 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
5198 argument, adjust users accordingly. Use build_pure_c_string where

5235 O_RDONLY already includes it).
5237 Stop ns builds setting the EMACSLOADPATH environment variable.
5238 * nsterm.m (ns_load_path): Rename from ns_init_paths.
5239 Now it does not set EMACSLOADPATH, just returns the load-path string.

5241 * lread.c [HAVE_NS]: Include nsterm.h.
5242 (init_lread) [HAVE_NS]: Use ns_load_path.

5252 (ns_init_paths): Do not set EMACSPATH.

5312 Move marker debugging code under MARKER_DEBUG.
5313 * marker.c (MARKER_DEBUG): Move marker debugging code under
5314 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
5315 for bootstrap with --enable-checking (~3x slowdown reported

5357 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
5358 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
5359 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
5360 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
5361 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
5362 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
5363 Fix pointer signedness problem.
5364 * xfaces.c (FRAME_X_FONT_TABLE):
5365 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
5367 2012-07-07 Glenn Morris <rgm@gnu.org>
5369 * lread.c (load_path_check): New function, split from init_lread.
5370 (init_lread): Reorganize. Motivation:
5371 If EMACSLOADPATH is set, check/warn about that rather than the
5372 defaults, which we are not going to use. Hence we can remove
5373 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
5374 Don't warn if site-lisp directories are missing.
5375 If not installed, start from a blank load-path, since
5376 PATH_LOADSEARCH refers to the eventual installation directories.
5378 2012-07-07 Eli Zaretskii <eliz@gnu.org>
5380 Support truncation and continuation glyphs on GUI frames, when
5381 fringes are disabled. (Bug#11832)
5382 * xdisp.c (init_iterator): Get dimensions of truncation and
5383 continuation glyphs even if on GUI frames.
5384 Adjust it->last_visible_x on GUI frames when the left or right fringes,
5385 or both, are absent.
5386 (start_display, move_it_in_display_line_to): Handle the case of a
5387 GUI frame without a fringe to display continuation or truncation
5389 (insert_left_trunc_glyphs): Support GUI frames: make sure
5390 truncation glyphs overwrite enough glyphs from the current line to
5391 have sufficient space in pixels.
5392 (display_line): Support truncation and continuation glyphs on GUI
5393 frames. If some spare pixels are left on the line after inserting
5394 the truncation glyphs, fill that space with a stretch glyph of a
5395 suitably computed width.
5397 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
5398 produce_glyphs, to support GUI sessions.
5400 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
5402 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
5404 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
5406 Do not require float-time's arg to fit in time_t (Bug#11825).
5407 This works better on hosts where time_t is unsigned, and where
5408 float-time is applied to the (negative) difference between two times.
5409 * editfns.c (decode_time_components): Last arg is now double *,
5410 not int *, and means to store all the result as a double, without
5411 worrying about whether the seconds part fits in time_t.
5412 All callers changed.
5413 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
5414 All callers changed.
5415 (Ffloat_time): Do not fail merely because the specified time falls
5416 outside of time_t range.
5418 2012-07-07 Glenn Morris <rgm@gnu.org>
5420 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
5421 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
5422 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).

5426 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
5427 Update dependencies.
5429 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
5431 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5433 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
5434 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
5435 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
5436 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
5437 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
5438 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
5440 * xfont.c (compare_font_names): Redo to omit the need for casts.
5442 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
5444 * xfns.c (Fx_change_window_property): Doc fix.
5445 * w32fns.c (Fx_change_window_property): Doc fix.
5447 * w32fns.c (Fx_window_property): Accept the same arguments as the
5448 X Windows version. Doc fix.
5449 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
5451 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
5452 Eli Zaretskii <eliz@gnu.org>
5454 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
5455 Windows-specific code from nt/config.nt moved here.
5456 Obsolete settings removed.
5458 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5460 * process.c: Avoid unnecessary calls to gettime.
5461 (wait_reading_process_output): Don't get the time of day
5462 when gobbling data immediately and not waiting, as there's no need
5463 for it in that case. This removes a FIXME.
5465 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
5467 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
5468 is defined (Bug#11768).
5470 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5472 Fix marker debugging code.
5473 * marker.c (byte_char_debug_check): Do not perform the check
5474 if buffer is not multibyte.
5475 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
5476 Call byte_char_debug_check with correct arguments.
5478 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5480 Compile marker debugging code only if ENABLE_CHECKING is defined.
5481 * marker.c (byte_char_debug_check, count_markers):
5482 Use only if ENABLE_CHECKING is defined.
5483 (byte_debug_flag): Remove.
5484 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
5485 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
5487 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5489 Avoid code repetition in marker-related functions.
5490 * marker.c (attach_marker): New function.
5491 (Fset_marker, set_marker_restricted, set_marker_both)
5492 (set_marker_restricted_both): Use it.
5493 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
5494 Consistently rename charno to charpos.
5495 (marker_position): Add eassert.
5496 (marker_byte_position): Convert to eassert.
5498 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5500 Simplify list operations in unchain_overlay and unchain_marker.

5504 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5506 Introduce fast path for the widely used marker operation.
5507 * alloc.c (build_marker): New function.
5508 * lisp.h (build_marker): New prototype.
5509 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
5510 * composite.c (autocmp_chars): Likewise.
5511 * editfns.c (buildmark): Remove.
5512 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
5513 (save_restriction_save): Use build_marker.
5514 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
5515 * window.c (save_window_save): Likewise.
5517 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5519 Do not use Fdelete_overlay in delete_all_overlays
5520 to avoid redundant calls to unchain_overlay.
5521 * buffer.c (drop_overlay): New function.
5522 (delete_all_overlays, Fdelete_overlay): Use it.
5523 * minibuf.c (get_minibuffer): Fix comment.
5525 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5527 Port to OpenBSD 5.1 amd64.
5528 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
5529 This is needed for OpenBSD, and should be harmless on all BSD systems.
5530 Also, include <sys/sysctl.h>, as it should be available on all
5531 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
5532 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
5533 use p_pid member, not kp_proc.pid.
5535 2012-07-06 Glenn Morris <rgm@gnu.org>
5537 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
5539 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5541 More xmalloc and related cleanup.
5542 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
5543 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
5544 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

5548 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
5549 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
5550 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
5552 Omit needless casts involving void * pointers and allocation.
5553 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
5554 as the former is more robust if P's type is changed.
5555 Prefer xzalloc to xmalloc + memset 0.
5556 Simplify malloc-or-realloc to realloc.
5557 Don't worry about xmalloc returning a null pointer.
5558 Prefer xstrdup to xmalloc + strcpy.
5559 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
5561 * keyboard.c (apply_modifiers_uncached): Prefer local array to
5562 alloca of a constant.
5564 2012-07-05 Eli Zaretskii <eliz@gnu.org>
5566 * xdisp.c (display_line): Fix horizontal pixel coordinates when
5567 hscroll is larger than the line width. Fixes long and futile
5568 looping inside extend_face_to_end_of_line (on a TTY) producing
5569 glyphs that are not needed and thrown away.
5571 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
5573 * marker.c (set_marker_restricted_both): Simplify by using
5576 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5578 * editfns.c (region_limit): Simplify by using clip_to_bounds.
5580 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
5582 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
5583 not defined (Bug#11768).
5584 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
5585 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
5586 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
5587 followed by gtk_box_set_homogeneous (Bug#11768).
5588 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
5589 (update_theme_scrollbar_width, xg_create_scroll_bar):
5590 Use gtk_scrollbar_new (Bug#11768).
5591 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
5592 (is_box_type): New function (Bug#11768).
5593 (xg_tool_item_stale_p): Call is_box_type.
5594 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
5595 with default display (Bug#11768).
5597 2012-07-05 Eli Zaretskii <eliz@gnu.org>
5599 * xdisp.c (window_hscroll_limited): New function.
5600 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
5601 coordinates when window's hscroll is set to insanely large
5604 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
5606 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
5607 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
5609 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
5612 * lisp.h (xzalloc): New prototype. Omit needless casts.
5613 * alloc.c (xzalloc): New function. Omit needless casts.

5665 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5667 * fileio.c (time_error_value): Check the right error number.
5668 Problem reported by Troels Nielsen in
5669 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
5671 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5673 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
5674 This should be fixed in a better way; see Eli Zaretskii in
5675 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
5676 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
5678 * fileio.c (time_error_value): Rename from special_mtime.
5679 The old name's problems were noted by Eli Zaretskii in
5680 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
5682 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
5683 This variable's comment says Emacs needs at least one GDB-visible
5684 symbol of type enum pvec_type, to work around GDB problems.
5685 The symbol's value doesn't matter.
5687 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
5688 that causes compilation to fail on pre-C99 compilers.
5690 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
5692 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
5693 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
5695 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5697 * buffer.c (init_buffer_once): Fix initialization of
5698 headers for buffer_defaults and buffer_local_symbols.
5699 Reported by Juanma Barranquero <lekktu@gmail.com>.
5701 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
5703 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
5704 * lisp.h (enum pvec_type): Use fewer bits.
5705 (PSEUDOVECTOR_SIZE_BITS): New constant.
5706 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
5707 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
5708 change in pvec_type.
5709 (PSEUDOVECTOR_TYPEP): New macro.
5710 (TYPED_PSEUDOVECTORP): Use it.
5711 * fns.c (internal_equal): Adapt code to extract pvectype.
5712 * emacs.c (gdb_pvec_type): Update type.
5713 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
5714 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
5715 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
5716 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
5717 (sweep_vectors): Use it. Use local var `total_bytes' instead of
5718 abusing vector->header.next.nbytes.
5719 (live_vector_p): Use PVEC_TYPE.
5720 (mark_object): Adapt code to extract pvectype. Use switch.
5722 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5724 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
5725 Tighten new eassert a bit.
5727 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5729 Fix compilation with --enable-gcc-warnings and -O1
5731 * doprnt.c (doprnt): Change type of tem to int, initialize
5732 to avoid compiler warning. Add eassert.
5733 * search.c (simple_search): Initialize match_byte to avoid
5734 compiler warning. Add eassert.
5736 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5738 Avoid weird behavior with large horizontal scrolls.
5739 Without this change, for example, large hscroll values would
5740 mess up Emacs's display on Fedora 15 x86, presumably due to
5741 overflows in int calculations in the display code.
5742 Also, if buffers had long lines, Emacs would freeze.
5743 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
5744 (set_window_hscroll): New function, containing the old guts of
5745 Fset_window_hscroll. Return the clipped value.
5746 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
5747 This avoids the need to check against PTRDIFF_MAX.
5749 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
5751 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5753 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
5755 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5757 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
5758 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
5759 since GCC 4.4.6 issues a bogus warning for them.
5761 Fix bugs in file timestamp newness comparisons.
5762 * fileio.c (Ffile_newer_than_file_p):
5763 * lread.c (Fload): Use full timestamp resolution of files,
5764 not just the 1-second resolution, so that files that are only
5765 slightly newer still count as newer.
5766 * fileio.c (Ffile_newer_than_file_p): Don't assume file
5767 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
5769 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
5771 * fileio.c: Improve handling of file time marker. (Bug#11852)
5772 (special_mtime): New function.
5773 (Finsert_file_contents, Fverify_visited_file_modtime):
5774 Use it to set special mtime values consistently.
5776 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
5778 * fileio.c (Finsert_file_contents): Properly handle st_mtime
5779 marker for non-existing file. (Bug#11852)
5781 2012-07-03 Glenn Morris <rgm@gnu.org>
5783 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
5784 and did not make it into globals.h).
5786 2012-07-03 Tom Tromey <tromey@redhat.com>

5832 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
5833 values which aren't power of 2.
5834 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
5835 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
5838 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
5840 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

5844 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5846 * alloc.c (allocate_vector_block): Remove redundant
5847 calls to mallopt if DOUG_LEA_MALLOC is defined.
5848 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
5849 avoid calls to mallopt if zero_vector is returned.
5851 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5853 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
5854 is enabled, avoid dereferencing NULL current_sblock if
5857 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5859 Cleanup basic buffer management.
5860 * buffer.h (struct buffer): Change layout to use generic vector
5861 marking code. Fix some comments. Change type of 'clip_changed'
5862 to bitfield. Remove unused #ifndef old.

5864 (GET_OVERLAYS_AT): Fix indentation.
5865 (for_each_per_buffer_object_at): New macro.
5866 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

5869 * alloc.c (allocate_buffer): Adjust to match new layout of
5870 struct buffer. Fix comment.
5871 (mark_overlay): New function.
5872 (mark_buffer): Use it. Use mark_vectorlike to mark normal
5873 Lisp area of struct buffer.
5874 (mark_object): Use it. Adjust marking of misc objects
5875 and related comments.
5877 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
5879 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
5880 wrapper that is not needed because the wrapped code is a no-op (zero
5881 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
5882 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
5884 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
5886 * alloc.c (mark_buffer): Simplify. Remove prototype.
5887 (mark_object): Add comment. Reorganize marking of vector-like
5888 objects. Use CHECK_LIVE for all vector-like objects except buffers
5889 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
5890 Avoid redundant calls to mark_vectorlike for bool vectors.
5892 2012-06-30 Glenn Morris <rgm@gnu.org>
5894 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
5896 * epaths.in (PATH_SITELOADSEARCH): New.
5897 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
5898 This is rather than relying on --enable-locallisppath elements
5899 having "site-lisp" in their names. (Bug#10208#25, 11658)
5901 2012-06-30 Eli Zaretskii <eliz@gnu.org>
5903 * w32proc.c (sys_select): Accept and ignore one more argument.
5905 * w32.c (emacs_gnutls_pull): Call select with one more argument.
5907 * sysselect.h [DOS_NT]: Don't include sys/select.h.
5908 (pselect) [!MS_DOS]: Redirect to sys_select.
5910 * sysdep.c: Don't include dos.h and dosfns.h.
5912 * process.c (sys_select):
5913 * msdos.c (sys_select): Accept one more argument and ignore it.
5915 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
5916 adapt data types and code to that.
5919 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
5920 which clashes with the gnulib function of the same name.
5922 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
5924 * font.c (font_style_to_value, font_style_symbolic)
5925 (font_prop_validate_style): Add type checks for values in
5928 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
5930 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
5933 2012-06-29 Eli Zaretskii <eliz@gnu.org>
5935 * xdisp.c (try_window_id): Undo last change.
5937 * w32.c (getwd): Adjust commentary about startup_dir.
5938 (init_environment): Always call sys_access, even in non-MSVC
5939 builds. Don't chdir to the directory of the Emacs executable.
5940 This undoes code from 1997 which was justified by the need to
5941 "avoid conflicts when removing and renaming directories". But its
5942 downside was that every relative file name was being interpreted
5943 relative to the directory of the Emacs executable, which can never
5944 be TRT. In particular, it broke sys_access when called with
5945 relative file names.
5946 (sys_access): Map GetLastError to errno.
5948 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5950 * window.h (struct window): Change type of 'fringes_outside_margins'

5970 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5972 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
5973 undefined. Convert from xassert to eassert.
5974 * nsmenu.m: Convert from xassert to eassert.

5990 * window.h (struct window): Change type of 'hscroll',
5991 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,

5993 Adjust users accordingly.
5994 * xdisp.c (try_cursor_movement): Replace type check with eassert.
5995 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
5996 from EMACS_INT to ptrdiff_t.
5997 (make_window): Omit redundant initialization.

6072 * alloc.c (allocate_string): Omit intervals initialization.
6073 * alloc.c (make_uninit_multibyte_string): Initialize intervals

6132 a better opportunity to optimize away calls to strlen when the
6133 function is called with compile-time constant argument.
6134 * image.c (imagemagick_error): Convert to build_string.
6135 * w32proc.c (sys_spawnve): Likewise.

6138 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
6140 Use sprintf return value instead of invoking strlen on result.
6141 In the old days this wasn't portable, since some sprintf
6142 implementations returned char *. But they died out years ago and
6143 Emacs already assumes sprintf returns int.
6144 Similarly for float_to_string.
6145 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

6152 * xfns.c (syms_of_xfns):
6153 Use sprintf or float_to_string result to avoid need to call strlen.
6154 * data.c (Fnumber_to_string):
6155 Use make_unibyte_string, since the string must be ASCII.
6156 * lisp.h, print.c (float_to_string): Now returns int length.
6157 * term.c (produce_glyphless_glyph):
6158 Use sprintf result rather than recomputing it.
6160 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

6193 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

6198 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
6199 instead of truncating it to 63 (admittedly a generous limit).
6201 * process.c: Fix spelling and caps in comments.
6203 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>

6283 Privately reported by Herbert J. Skuhra.
6284 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
6286 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,

6319 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
6321 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
6322 Privately reported by Herbert J. Skuhra.
6323 [__FreeBSD__]: Remove "*/" typo after "#include".
6324 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
6325 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
6326 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
6327 Don't assume EMACS_TIME and struct timeval are the same type.
6329 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
6331 Support higher-resolution time stamps (Bug#9000).
6332 The time stamps are only nanosecond-resolution at the C level,
6333 since that's the best that any real-world system supports now.
6334 But they are picosecond-resolution at the Lisp level, as that's
6335 easy, and leaves room for future OS improvements.
6337 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
6340 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
6341 Don't get current time unless it's needed.
6343 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
6344 now provides it if it's absent.
6345 (start_atimer): Port to higher-res time stamps.
6346 Check for time stamp overflow. Don't get current time more
6347 often than is needed.
6349 * buffer.h (struct buffer): Buffer modtime now has high resolution.
6350 Include systime.h, not time.h.
6351 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
6353 * dired.c: Include stat-time.h.
6354 (Ffile-attributes): File times now have higher resolution.

6357 (struct image): Timestamp now has higher resolution.
6359 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
6360 has at least microseconds now. All uses removed.
6361 (update_frame, update_single_window, update_window, update_frame_1)
6362 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
6363 (duration_to_sec_usec): Remove; no longer needed.
6365 * editfns.c (time_overflow): Now extern.

6371 (decode_time_components, lisp_seconds_argument): New functions.
6372 (make_time): Now static.
6373 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
6374 Report an error if the time is invalid, rather than having the caller
6377 * fileio.c: Include <stat-time.h>
6378 (Fcopy_file): Copy higher-resolution time stamps.
6379 Prefer to set the time stamp via a file descriptor if that works.

6381 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
6382 (Fvisited_file_modtime, Fset_visited_file_modtime):
6383 Support higher-resolution time stamps.
6385 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
6387 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
6389 * image.c (prepare_image_for_display, clear_image_cache)
6390 (lookup_image): Port to higer-resolution time stamps.
6392 * keyboard.c (start_polling, bind_polling_period):
6393 Check for time stamp overflow.
6394 (read_char, kbd_buffer_get_event, timer_start_idle)
6395 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
6396 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
6397 Port to higher-resolution time stamps. Do not assume time_t is signed.
6398 (decode_timer): New function. Timers are now vectors of length 9,
6399 not 8, to accommodate the picosecond component.
6400 (timer_check_2): Use it.
6402 * nsterm.m (select_timeout, timeval_subtract): Remove.
6403 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
6404 as they're a bit more accurate and handle overflow better.
6405 (ns_select): Change prototype to be compatible with pselect.
6406 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
6407 * nsterm.h (ns_select): Adjust prototype.
6409 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
6410 us-resolution time stamps.
6411 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
6413 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
6415 * lisp.h (time_overflow): New decl.
6416 (wait_reading_process_output): First arg is now intmax_t, not int,
6417 to accommodate larger waits.
6419 * process.h (struct Lisp_Process.read_output_delay):
6420 Now counts nanoseconds, not microseconds.
6421 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
6423 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
6424 (wait_reading_process_output):
6425 Port to ns-resolution time stamps.
6426 (Faccept_process_output, wait_reading_process_output):
6427 Check for time stamp overflow. Do not assume time_t is signed.
6428 (select_wrapper): Remove; we now use pselect.
6429 (Fprocess_attributes): Now generates ns-resolution time stamps.
6431 * sysdep.c: Include utimens.h. Don't include utime.h
6432 or worry about struct utimbuf; gnulib does that for us now.
6433 (gettimeofday): Remove; gnulib provides a substitute.
6434 (make_timeval): New function.
6435 (set_file_times): Now sets ns-resolution time stamps.
6436 New arg FD; all uses changed.
6437 (time_from_jiffies, ltime_from_jiffies, get_up_time)
6438 (system_process_attributes):
6439 Now returns ns-resolution time stamp. All uses changed.
6440 Check for time stamp overflow.
6442 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
6443 provides a substitute now.
6445 * systime.h: Include timespec.h rather than sys/time.h and time.h,
6446 since it guarantees struct timespec.
6447 (EMACS_TIME): Now struct timespec, so that we can support
6448 ns-resolution time stamps.
6449 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
6450 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
6451 (EMACS_USECS): Remove.
6452 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
6453 so multiply the arg by 1000 before storing it.
6454 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
6456 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
6457 Port to ns-resolution time stamps.
6458 (EMACS_TIME_NEG_P): Remove; replaced by....
6459 (EMACS_TIME_SIGN): New macro.
6460 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
6461 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
6462 (set_file_times, make_time, lisp_time_argument): Adjust signature.
6463 (make_timeval, make_lisp_time, decode_time_components): New decls.
6464 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
6465 that it mishandled time_t overflow. You can't compare by subtracting!
6466 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
6467 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
6469 * term.c: Include <sys/time.h>.
6470 (timeval_to_Time): New function, for proper overflow wraparound.
6471 (term_mouse_position, term_mouse_click): Use it.
6473 * undo.c (record_first_change): Support higher-resolution time stamps
6475 (Fprimitive_undo): Use them when restoring time stamps.
6477 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
6478 (w32_get_internal_run_time):
6479 Port to higher-resolution Emacs time stamps.
6480 (ltime): Now accepts single 64-bit integer, as that's more convenient
6483 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
6485 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
6486 for compatibility with pselect. Support ns-resolution time stamps.
6488 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
6490 * xselect.c (wait_for_property_change, x_get_foreign_selection):
6491 Check for time stamp overflow, and support ns-resolution time stamps.
6493 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
6494 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
6495 (timeval_subtract): Remove; no longer needed.
6496 (XTflash, XTring_bell, x_wait_for_event):
6497 Port to ns-resolution time stamps. Don't assume time_t is signed.
6499 2012-06-22 Chong Yidong <cyd@gnu.org>

6503 2012-06-22 Eli Zaretskii <eliz@gnu.org>
6505 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
6506 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
6507 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
6508 staticidx goes up to 1597 out of 1600 = 0x640.)
6510 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
6512 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
6513 Otherwise, the umask might be mistakenly 0 while handling input signals.
6515 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
6517 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

6523 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
6524 access to `contents' member of Lisp_Vector objects with AREF and ASET
6527 2012-06-19 Chong Yidong <cyd@gnu.org>
6529 * frame.c (delete_frame): When selecting a frame on a different
6530 text terminal, do not alter the terminal's top-frame.

6534 (unwind_format_mode_line): Restore them.
6535 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
6537 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
6538 since tty frames can be explicitly named.
6539 (prepare_menu_bars): Likewise.
6541 * term.c (Ftty_top_frame): New function.
6543 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

6546 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
6547 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
6548 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
6549 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
6550 (METER_1, METER_2): Simplify.
6552 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

6556 2012-06-18 Martin Rudalics <rudalics@gmx.at>
6558 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
6559 gets killed during executing of this function (Bug#11665).
6560 Try to always return Qt when the buffer has been actually killed.
6561 (Vkill_buffer_query_functions): In doc-string say that functions
6562 run by this hook should not change the current buffer.
6564 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
6566 Fix recently-introduced process.c problems found by static checking.
6567 * process.c (write_queue_push, write_queue_pop, send_process):

6584 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
6586 * lisp.h (eassert): Assume C89 or later.
6587 This removes the need for CHECK.
6588 (CHECK): Remove. Its comments about always evaluating its
6589 argument were confusing, as 'eassert' typically does not evaluate
6592 * coding.c (produce_chars): Use ptrdiff_t, not int.
6594 * xterm.c (x_draw_underwave): Check for integer overflow.
6595 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

6689 If all the glyphs of the glyph row came from strings, and we have no
6690 cursor positioning clues, put the cursor on the first glyph of the

6779 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
6780 code works fine either way, and efficiency is not a concern here,
6781 as the union type is for debugging, not for production.
6782 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
6783 Use an inline function on all platforms when using the union type,
6784 since this is simpler and 'static inline' can be used portably
6786 (LISP_INITIALLY_ZERO): New macro.
6787 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
6788 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

6928 * doprnt.c (doprnt): Truncate multibyte char correctly.
6929 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
6930 would mishandle a string argument "Xc" if X was a multibyte
6931 character of length 2: it would truncate after X's first byte
6932 rather than including all of X.
6934 2012-06-06 Chong Yidong <cyd@gnu.org>
6936 * buffer.c (word_wrap): Doc fix.

6989 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
6991 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
6994 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
6996 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
6998 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
7000 For a 'struct window', replace some Lisp_Object fields to
7001 bitfields where appropriate, remove unused fields.
7002 * window.h (struct window): Remove unused 'last_mark_x' and
7003 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
7004 change it's type from Lisp_Object to bitfield.
7005 Change type of 'force_start', 'optional_new_start',
7006 'last_had_star', 'update_mode_line' and 'start_at_line_beg'

7009 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
7011 Pacify gcc -Wdouble-precision when using Xaw.

7013 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
7014 Use 'float' consistently, rather than 'float' in most places
7015 and 'double' in a couple of places.
7017 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7019 * xdisp.c (handle_stop): Detect whether we have overlay strings
7020 loaded by testing it->current.overlay_string_index to be
7021 non-negative, instead of checking whether n_overlay_strings is
7022 positive. (Bug#11587)
7024 2012-05-31 Chong Yidong <cyd@gnu.org>
7026 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
7028 * doc.c (Fsubstitute_command_keys): Doc fix.
7030 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7032 * search.c (search_buffer): Remove calls to
7033 r_alloc_inhibit_buffer_relocation, as it is now called by
7034 maybe_unify_char, which was the cause of relocation of buffer text
7037 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7039 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
7040 for the duration of call to load_charset, to avoid problems with
7041 callers of maybe_unify_char that access buffer text through C
7044 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
7045 decrement the inhibition flag, instead of just setting or
7048 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
7050 Remove obsolete '#define static' cruft.
7051 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
7052 This #undef was "temporary" in 2000; it is no longer needed
7053 now that '#define static' has gone away.
7054 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
7055 (gray_bitmap_bits): Remove; no longer needed.
7056 All uses replaced with definiens.
7057 * xterm.c: Include "bitmaps/gray.xbm".
7059 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
7061 Clean up __executable_start, monstartup when --enable-profiling.
7062 The following changes affect the code only when profiling.
7063 * dispnew.c (__executable_start): Rename from safe_bcopy.
7064 Define only on platforms that need it.
7065 * emacs.c: Include <sys/gmon.h> when profiling.
7066 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.

7068 (safe_bcopy): Remove decl; no longer has that name.
7069 (main): Coalesce #if into single bit of code, for simplicity.

7099 Do not create empty overlays with the evaporate property (Bug#9642).
7100 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
7101 Bug#9642, but explicitly check that the buffer the overlay would
7102 be moved to is live and rearrange lines to make sure that errors
7103 will not put the overlay in an inconsistent state.
7104 (Fdelete_overlay): Cosmetics.
7106 2012-05-28 Eli Zaretskii <eliz@gnu.org>
7108 * w32term.c (my_bring_window_to_top): New function.

7120 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
7122 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
7123 This avoids undefined behavior that might cause the eassert
7124 to not catch an out-of-range value.
7126 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
7128 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

7142 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
7143 Only r_alloc_inhibit_buffer_relocation needed to be added;
7144 the others were already declared.
7146 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
7147 before checking whether it's out of range. Put the check inside
7149 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
7151 2012-05-27 Ken Brown <kbrown@cornell.edu>

7158 * lisp.h [REL_ALLOC]: Add prototypes for external functions
7159 defined on ralloc.c.
7161 * buffer.c [REL_ALLOC]: Remove prototypes of
7162 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
7163 they are now on lisp.h.
7165 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
7167 * search.c (search_buffer): Use it to inhibit relocation of buffer
7168 text while re_search_2 is doing its job, because re_search_2 is
7169 passed C pointers to buffer text. (Bug#11519)
7171 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
7174 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator

7179 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
7182 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
7184 Fix coding-related core dumps with gcc -ftrapv.
7185 The code was computing A - B, where A and B are pointers, and B is
7186 random garbage. This can lead to core dumps on platforms that
7187 have special pointer registers, and it also leads to core dumps on
7188 x86-64 when compiled with gcc -ftrapv. The fix is to compute
7189 A - B only when B is initialized properly.
7190 * coding.c (coding_set_source, coding_set_destination): Return void.
7191 (coding_change_source, coding_change_destinations): New functions,
7192 with the old behaviors of coding_set_source and coding_set_destination.

7197 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
7199 2012-05-26 Eli Zaretskii <eliz@gnu.org>
7201 Extend mouse support on W32 text-mode console.
7202 * xdisp.c (draw_row_with_mouse_face):
7203 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
7205 * w32console.c: Include window.h.
7206 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
7208 (initialize_w32_display): Initialize mouse-highlight data.
7210 * w32inevt.c: Include termchar.h and window.h.
7211 (do_mouse_event): Support mouse-autoselect-window. When the mouse
7212 moves, call note_mouse_highlight. If help_echo changed, call
7213 gen_help_event to produce help-echo message in the echo area.
7214 Call clear_mouse_face if mouse_face_hidden is set in the mouse
7217 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
7219 * lread.c (read1): Simplify slightly to avoid an overflow warning
7220 with GCC 4.7.0 on x86-64.
7222 2012-05-26 Eli Zaretskii <eliz@gnu.org>
7224 * bidi.c (bidi_mirror_char): Revert last change: an int is
7225 definitely wide enough here.

7237 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
7239 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7240 (allocate_pseudovector):
7241 Use int, not EMACS_INT, where int is wide enough.
7242 (inhibit_garbage_collection, Fgarbage_collect):
7243 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7244 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
7245 int might not be wide enough.

7263 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7264 (validate_region): Omit unnecessary test for b <= e,
7265 since that's guaranteed by the previous test.

7267 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
7268 (report_overlay_modification):
7269 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7270 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

7272 after the EMACS_INT -> ptrdiff_t change.

7274 * buffer.h: Adjust decls to match defn changes elsewhere.

7279 not int, to avoid needless 32-bit limit on 64-bit hosts.
7280 (exec_byte_code): Use tighter memory-full test, one that checks
7281 for alloca overflow. Don't compute the address of the object just
7282 before an array, as that's not portable. Use EMACS_INT, not
7283 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
7284 * callint.c (Fcall_interactively):
7285 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

7298 (casify_object): Avoid integer overflow when overallocating buffer.
7299 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

7302 * category.h (CATEGORYP): Don't assume arg is nonnegative.

7306 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7307 For CCL_MapSingle, check that content and value are in int range.

7310 (resolve_symbol_ccl_program): Check that vector header is in range.
7311 Always copy the vector, so that we can check its contents reliably
7312 now rather than having to recheck each instruction as it's being
7313 executed. Check that vector words fit in 'int'.
7314 (ccl_get_compiled_code, Fregister_ccl_program)

7342 Don't rely on undefined behavior with signed left shift overflow.
7343 Don't assume unsigned int fits into fixnum, or that fixnum fits
7344 into unsigned int. Don't require max_code to be a valid fixnum;
7345 that's not true for gb10830 4-byte on a 32-bit host. Allow
7346 invalid_code to be a cons, for the same reason. Require code_offset
7347 to be a character. Avoid int overflow if max_char is close
7349 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
7350 this is intended anyway and avoids some undefined behavior.
7351 (load_charset_map): Pass unsigned, not int, as 2nd arg of
7352 INDEX_TO_CODE_POINT, as that's what it expects.
7353 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
7354 * charset.h (DECODE_CHAR): Return int, not unsigned;
7355 this is what was intended anyway, and it avoids undefined behavior.
7356 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
7357 integer-overflow issues.
7358 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
7359 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
7360 where the argument is EMACS_INT, and this behavior is not intended.
7361 * chartab.c (Fmake_char_table, Fset_char_table_range)
7362 (uniprop_get_decoder, uniprop_get_encoder):
7363 Don't assume fixnum fits in int.
7364 * cmds.c (move_point): New function, that does the gist of
7365 Fforward_char and Fbackward_char, but does so while checking
7366 for integer overflow more accurately.
7367 (Fforward_char, Fbackward_char): Use it.
7368 (Fforward_line, Fend_of_line, internal_self_insert)
7369 (internal_self_insert):

8029 2012-05-25 Glenn Morris <rgm@gnu.org>
8031 * lisp.mk (lisp): Update for more files being compiled now.
8033 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
8035 * lread.c: Remove `read_pure' which makes no difference.
8036 (read_pure): Remove var.
8037 (unreadpure): Remove function.
8038 (readevalloop): Don't call read_list with -1 flag.

8051 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
8053 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
8056 This directory predates autoconf and is no longer needed nowadays.
8057 Move its few remaining bits of functionality to where they're needed.
8058 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

8067 (EMACS_UINT): Define unconditionally now.
8068 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
8069 (BITS_PER_EMACS_INT): New constants, replacing
8070 what used to be in config.h, but not useful in #if.
8071 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
8072 define them any more.
8073 (VAL_MAX): New macro.
8075 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
8076 BITS_PER_EMACS_INT, in #if.
8077 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
8078 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
8079 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
8080 * s/ms-w32.h (DATA_START):
8081 Move here from removed file m/intel386.h.
8082 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
8083 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
8085 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
8087 Assume C89 or later.

8097 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
8098 * xterm.c (input_signal_count): Assume volatile works.
8100 2012-05-21 Ken Brown <kbrown@cornell.edu>
8102 * xgselect.c (xg_select): Fix first argument in call to 'select'
8105 2012-05-20 Ken Brown <kbrown@cornell.edu>
8107 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
8108 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
8110 2012-05-19 Ken Brown <kbrown@cornell.edu>
8112 * xfns.c (x_in_use): Remove `static' qualifier.
8113 * xterm.h (x_in_use): Declare.
8114 * xgselect.c: Include xterm.h.
8115 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
8116 and `display_arg' (bug#9754).
8118 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
8120 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
8122 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
8123 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
8125 2012-05-18 Eli Zaretskii <eliz@gnu.org>
8127 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
8129 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
8130 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
8132 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
8133 reference to image_cache->refcount.
8134 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
8136 2012-05-17 Juri Linkov <juri@jurta.org>
8138 * search.c (Fword_search_regexp, Fword_search_backward)
8139 (Fword_search_forward, Fword_search_backward_lax)
8140 (Fword_search_forward_lax): Move functions to isearch.el
8141 (bug#10145, bug#11381).
8143 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
8145 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
8147 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
8149 * lread.c (init_obarray): Declare Qt and Qnil as special.
8151 2012-05-14 Glenn Morris <rgm@gnu.org>
8153 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
8154 Put "libexec" before "bin", for the sake of init_callproc_1.
8156 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
8158 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
8160 * unexaix.c: Port to more-recent AIX compilers.
8161 (report_error, report_error_1, make_hdr, copy_sym)
8162 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
8163 Make arguments const char *, not char *, to avoid violations of C
8164 standard and to fix some AIX warnings reported by Gilles Pion.
8166 2012-05-14 Eli Zaretskii <eliz@gnu.org>
8168 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
8169 already have overlays loaded.
8170 (handle_single_display_spec): Before returning without displaying
8171 fringe bitmap, synchronize the bidi iterator with the main display
8172 iterator, by calling iterate_out_of_display_property.
8173 (iterate_out_of_display_property): Detect buffer iteration by
8174 testing that it->string is a Lisp string.
8175 (get_next_display_element): When the current object is exhausted,
8176 and there's something on it->stack, call set_iterator_to_next to
8177 proceed with what's on the stack, instead of returning zero.
8178 (set_iterator_to_next): If called at the end of a Lisp string,
8179 proceed to consider_string_end without incrementing string
8180 position. Don't increment display vector index past the end of
8181 the display vector. (Bug#11417)
8182 (pos_visible_p): Don't report a position visible when move_it_to
8183 stopped at the last line of window, which happens to be scanned
8184 backwards by the bidi iteration. (Bug#11464)
8186 2012-05-14 Eli Zaretskii <eliz@gnu.org>
8188 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
8189 and right-margin display specs even if the spec is invalid or we
8190 are on a TTY, and thus unable to display on the fringes.
8191 That's because the text with the property will not be displayed anyway,
8192 so we need to signal to the caller that this is a "replacing"
8193 display spec. This fixes display when the spec is invalid or we
8196 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
8198 * unexaix.c (make_hdr): Fix typo in prototype.
8199 This bug broke the build on AIX. Problem reported by Gilles Pion.
8201 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
8203 * keyboard.c (kbd_buffer_get_event): Read special events also in
8204 batch mode. (Bug#11415)
8206 2012-05-12 Glenn Morris <rgm@gnu.org>
8208 * ns.mk: Update for ns_appbindir no longer having trailing "/".
8210 2012-05-12 Eli Zaretskii <eliz@gnu.org>
8212 * lisp.mk (lisp): Add newcomment.elc.
8214 2012-05-12 Glenn Morris <rgm@gnu.org>
8216 * Makefile.in (MKDIR_P): New, set by configure.
8217 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
8219 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
8221 Remove unused function hourglass_started.
8222 * dispextern.h (hourglass_started):
8223 * w32fns.c (hourglass_started):
8224 * xdisp.c (hourglass_started): Remove.
8226 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
8228 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
8229 Update dependencies.
8231 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
8233 * xgselect.c (xg_select): Put maxfds+1 into a var.
8234 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
8236 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
8238 2012-05-10 Dave Abrahams <dave@boostpro.com>
8240 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
8241 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
8243 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
8245 * dbusbind.c (xd_registered_buses): New internal Lisp object.
8246 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
8247 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
8248 Initialize xd_registered_buses.
8250 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
8252 Untag more efficiently if USE_LSB_TAG.
8253 This is based on a proposal by YAMAMOTO Mitsuharu in
8254 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
8255 For an admittedly artificial (nth 8000 longlist) benchmark on
8256 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
8257 Emacs's overall text size by 1%.
8258 * lisp.h (XUNTAG): New macro.
8259 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
8260 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
8261 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
8262 * eval.c (Fautoload):
8263 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
8264 * frame.h (XFRAME): Use XUNTAG.
8266 Port recent dbusbind.c changes to 32-bit --with-wide-int.
8267 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
8268 Remove unportable assumptions about print widths of types like
8270 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
8271 intptr_t when converting between pointer and integer, to avoid GCC
8272 warnings about wrong width.
8274 2012-05-09 Eli Zaretskii <eliz@gnu.org>
8276 * w32proc.c (new_child): Force Windows to reserve only 64KB of
8277 stack for each reader_thread, instead of defaulting to 8MB
8278 determined by the linker. This avoids failures in creating
8279 subprocesses on Windows 7, see the discussion in this thread:
8280 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
8282 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
8284 Fix up display of the *Minibuf-0* buffer in the mini window.
8285 * keyboard.c (read_char): Don't clear the echo area if there's no
8287 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
8288 contents of *Minibuf-0*) if there's no message displayed in its stead.
8290 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
8292 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
8295 2012-05-06 Chong Yidong <cyd@gnu.org>
8297 * lisp.mk (lisp): Update.
8299 2012-05-05 Jim Meyering <meyering@redhat.com>
8301 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
8303 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
8305 * data.c (PUT_ERROR): New macro.
8306 (syms_of_data): Use it. Add new error type `user-error'.
8307 * undo.c (user_error): New function.
8308 (Fprimitive_undo): Use it.
8309 * print.c (print_error_message): Adjust print style for `user-error'.
8310 * keyboard.c (user_error): New function.
8311 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
8313 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
8315 Do not limit current-time-string to years 1000..9999.
8316 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
8317 (Fcurrent_time_string): Support any year that is supported by the
8318 underlying localtime representation. Don't use asctime, as it
8319 has undefined behavior for years outside the range -999..9999.
8321 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
8323 Fix race conditions involving setenv, gmtime, localtime, asctime.
8324 Without this fix, interrupts could mess up code that uses these
8325 nonreentrant functions, since setting TZ invalidates existing
8326 tm_zone or tzname values, and since most of these functions return
8327 pointers to static storage.
8328 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
8329 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
8330 Grow the critical sections to include not just invoking
8331 localtime/gmtime, but also accessing these functions' results
8332 including their tm_zone values if any, and any related TZ setting.
8333 (format_time_string): Last arg is now struct tm *, not struct tm **,
8334 so that the struct tm is saved in the critical section.
8335 All callers changed. Simplify allocation of initial buffer, partly
8336 motivated by the fact that memory allocation needs to be outside
8337 the critical section.
8339 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
8341 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
8342 with RESET_INTERVAL.
8344 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
8345 Remove duplicated buffer name initialization.
8347 2012-05-02 Jim Meyering <jim@meyering.net>
8349 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
8351 * xfns.c (x_window): Use xstrdup (Bug#11375).
8353 2012-05-02 Eli Zaretskii <eliz@gnu.org>
8355 * xdisp.c (pos_visible_p): If already at a newline from the
8356 display string before the 'while' loop, don't walk back the glyphs
8357 from it3.glyph_row. Solves assertion violation when the display
8358 string begins with a newline (egg.el). (Bug#11367)
8360 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
8362 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
8365 2012-05-01 Glenn Morris <rgm@gnu.org>
8367 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
8368 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
8369 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
8370 All were removed before 23.1.
8372 * dispnew.c: Remove HAVE_LIBNCURSES test;
8373 it is always true on relevant platforms.
8375 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
8376 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
8378 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
8380 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
8382 * .gdbinit (xpr): Remove checks for no longer existing misc types.
8383 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
8386 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
8388 Do not avoid creating empty evaporating overlays (Bug#9642).
8389 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
8390 That is, do not delete an evaporating overlay if it becomes
8391 empty after its bounds are adjusted to fit within its buffer.
8392 This fix caused other problems, and I'm reverting it until we get
8393 to the bottom of them.
8395 2012-04-27 Chong Yidong <cyd@gnu.org>
8397 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
8399 2012-04-27 Eli Zaretskii <eliz@gnu.org>
8401 * xdisp.c (pos_visible_p): If the window start position is beyond
8402 ZV, start the display from buffer beginning. Prevents assertion
8403 violation in init_iterator when the minibuffer window is scrolled
8406 * window.c (window_scroll_pixel_based): Likewise.
8408 2012-04-27 Chong Yidong <cyd@gnu.org>

8424 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
8425 display element, check also the underlying string or buffer
8426 character. (Bug#11341)
8428 * w32menu.c: Include w32heap.h.
8429 (add_menu_item): If the call to AppendMenuW (via
8430 unicode_append_menu) fails, disable Unicode menus only if we are
8431 running on Windows 9X/Me.
8433 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
8435 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

8438 2012-04-24 Martin Rudalics <rudalics@gmx.at>
8440 * keyboard.c (read_char): Don't wipe echo area for select window

8452 now a cons (bug#11311).
8454 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
8456 Do not create empty overlays with the evaporate property (Bug#9642).
8457 * buffer.c (Fmove_overlay): Delete an evaporating overlay
8458 if it becomes empty after its bounds are adjusted to fit within
8459 its buffer. Without this fix, in a nonempty buffer (let ((o
8460 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
8461 yields an empty overlay that has the evaporate property, which is
8462 not supposed to happen.
8464 Fix minor GTK3 problems found by static checking.
8465 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

8602 (print_object): Check for cycles even when print-circle is nil and
8603 print-gensym is t, but only check print_depth if print-circle is nil.
8605 2012-04-20 Chong Yidong <cyd@gnu.org>
8607 * process.c (wait_reading_process_output): If EIO occurs on a pty,
8608 set the status to "failed" and ensure that sentinel is run.

8663 New extern decls, to avoid calling undeclared functions.
8664 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
8665 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
8666 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

8683 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
8684 Remove decls. This fixes an "It stinks!".
8686 * alloc.c (which_symbols): Fix alignment issue / type clash.
8688 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
8690 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

8711 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
8713 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

8736 2012-04-11 Daniel Colascione <dancol@dancol.org>
8738 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
8739 against is gone. It's better to use vfork now so that when Cygwin
8740 gains a new, working vfork, we use it automatically (bug#10398).
8742 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

8782 * gnutls.c (gnutls_log_function2i): Convenience log function.
8783 (emacs_gnutls_read): Use new log functions,
8784 `gnutls_handshakes_tried' process member, and
8785 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
8786 attempts per process (connection).

8797 2012-04-09 Eli Zaretskii <eliz@gnu.org>
8799 * xdisp.c (set_cursor_from_row): If the display string appears in
8800 the buffer at position that is closer to point than the position
8801 after the display string, display the cursor on the first glyph of
8802 the display string. Fixes cursor display when a 'display' text
8803 property immediately follows invisible text. (Bug#11094)
8805 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
8807 composite.c: use 'double' consistently
8808 * composite.c (get_composition_id): Use 'double' consistently
8809 instead of converting 'float' to 'double' and vice versa; this is
8810 easier to understand and avoids a GCC warning.
8812 2012-04-09 Glenn Morris <rgm@gnu.org>
8814 * Makefile.in: Generate leim-list with bootstrap-emacs, in
8815 preparation for dumping it with emacs. (Bug#4789)

8859 [!WINDOWSNT]: New macros.
8860 (init_libxml2_functions, libxml2_loaded_p): New functions.
8861 (parse_region): Call fn_xmlCheckVersion instead of using the macro
8862 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
8863 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
8864 Calls xmlCleanupParser only if libxml2 was loaded (or statically
8866 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
8867 Call init_libxml2_functions before calling libxml2 functions.
8868 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
8870 * emacs.c: Don't include libxml/parser.h.
8871 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
8872 xmlCleanupParser directly.
8874 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
8876 2012-04-07 Eli Zaretskii <eliz@gnu.org>
8878 * indent.c (Fvertical_motion): If there is a display string at
8879 point, use it.vpos to compute how many lines to backtrack after

8884 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
8885 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
8886 about subtle differences between FETCH_CHAR* and STRING_CHAR*
8887 macros related to unification of CJK characters. For the details,
8888 see the discussion following the message here:
8889 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
8891 2012-04-04 Chong Yidong <cyd@gnu.org>
8893 * keyboard.c (Vdelayed_warnings_list): Doc fix.
8895 2012-04-01 Eli Zaretskii <eliz@gnu.org>
8897 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
8898 instead of alloca. (Bug#11138)
8900 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
8902 * w32menu.c (is_simple_dialog): Properly check lisp types.
8905 2012-03-31 Eli Zaretskii <eliz@gnu.org>
8907 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
8908 position we get to after a call to move_it_to fails the
8909 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
8910 only if we wind up in a string from display property. (Bug#11063)
8912 * window.c (Fdelete_other_windows_internal): Invalidate the row
8913 and column information about mouse highlight, so that redisplay
8914 restores it after reallocating the glyph matrices. (Bug#7464)
8916 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
8917 string comes from a `display' text property, use the buffer
8918 position of that property as if we actually saw that position in
8920 (move_it_by_lines): Remove the assertion that
8921 "it->current_x == 0 && it->hpos == 0" which can be legitimately
8922 violated when there's a before-string at the beginning of a line.
8925 2012-03-30 Eli Zaretskii <eliz@gnu.org>
8927 * xdisp.c (append_space_for_newline): If the default face was
8928 remapped, use the remapped face for the appended newline.
8929 (extend_face_to_end_of_line): Use the remapped default face for
8930 extending the face to the end of the line.
8931 (display_line): Call extend_face_to_end_of_line when the default
8932 face was remapped. (Bug#11068)
8934 2012-03-29 Eli Zaretskii <eliz@gnu.org>
8936 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
8938 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
8940 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
8942 2012-03-27 Glenn Morris <rgm@gnu.org>
8944 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
8947 2012-03-26 Kenichi Handa <handa@m17n.org>
8949 * dispextern.h (struct glyph): Fix previous change. Change the
8950 bit length of glyphless.ch to 25 (Bug#11082).
8952 2012-03-26 Chong Yidong <cyd@gnu.org>
8954 * keyboard.c (Vselection_inhibit_update_commands): New variable.
8955 (command_loop_1): Use it; inhibit selection update for
8956 handle-select-window too (Bug#8996).
8958 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
8960 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
8962 2012-03-25 Kenichi Handa <handa@m17n.org>
8964 * dispextern.h (struct glyph): Change the bit length of
8965 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
8967 2012-03-24 Eli Zaretskii <eliz@gnu.org>
8969 * s/ms-w32.h (tzname): Include time.h before redirecting to
8970 _tzname. Fixes the MSVC build. (Bug#9960)
8972 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
8974 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
8977 * xterm.c (XTread_socket): Only modify handling_signal if
8978 !SYNC_INPUT. (Bug#11080)
8980 2012-03-23 Eli Zaretskii <eliz@gnu.org>
8982 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
8983 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
8984 when fetching a multibyte character consumes more bytes than
8985 CHAR_BYTES returns, due to unification of CJK characters in
8986 string_char. (Bug#11073)
8988 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
8990 * process.c (wait_reading_process_output): Handle pty disconnect
8991 by refraining from sending oneself a SIGCHLD (bug#10933).
8993 2012-03-22 Chong Yidong <cyd@gnu.org>
8995 * dispextern.h (struct it): New member string_from_prefix_prop_p.
8997 * xdisp.c (push_prefix_prop): Rename from push_display_prop.

9004 * xfaces.c (Vface_remapping_alist): Doc fix.
9006 2012-03-20 Eli Zaretskii <eliz@gnu.org>
9008 * w32proc.c (Fw32_set_console_codepage)
9009 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
9012 2012-03-20 Chong Yidong <cyd@gnu.org>
9014 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
9015 to reflect default non-nil value of redisplay-dont-pause.
9017 2012-03-19 Kenichi Handa <handa@m17n.org>
9019 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
9020 it fit in a valid range (Bug#11003).
9022 2012-03-18 Eli Zaretskii <eliz@gnu.org>
9024 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
9025 that is not from display property, accept the row as a "cursor
9026 row" if one of the string's character has a non-nil `cursor'
9027 property. Fixes cursor positioning when there are newlines in
9028 overlay strings, e.g. in icomplete.el. (Bug#11035)
9030 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
9032 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
9034 2012-03-12 Chong Yidong <cyd@gnu.org>
9036 * eval.c (inhibit_lisp_code): Rename from
9037 inhibit_window_configuration_change_hook; move from window.c.
9039 * xfns.c (unwind_create_frame_1, Fx_create_frame):
9040 * window.c (run_window_configuration_change_hook)
9041 (syms_of_window): Callers changed.
9043 2012-03-11 Chong Yidong <cyd@gnu.org>

9056 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
9058 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
9060 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
9061 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
9064 2012-03-03 Glenn Morris <rgm@gnu.org>
9066 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
9068 2012-03-02 Eli Zaretskii <eliz@gnu.org>
9070 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
9071 position past the first glyph_row that ends at ZV. (Bug#10902)
9072 (redisplay_window, next_element_from_string): Fix typos in
9074 (redisplay_window): Pass to move_it_vertically the margin in
9075 pixels, not in screen lines.
9077 2012-03-02 Glenn Morris <rgm@gnu.org>
9079 * buffer.c (buffer-list-update-hook): Doc fix.
9081 2012-02-29 Eli Zaretskii <eliz@gnu.org>
9083 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
9084 push_it before setting up the iterator for the first overlay
9085 string, even if we have an empty string loaded.
9086 (next_overlay_string): If there's an empty string on the iterator
9087 stack, pop the stack. (Bug#10903)
9089 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
9091 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
9092 Suggested by Stefan Monnier in
9093 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
9094 * alloc.c (widen_to_Lisp_Object): New static function.
9095 (mark_memory): Also mark Lisp_Objects by fetching pointer words
9096 and widening them to Lisp_Objects. This would work even if
9097 USE_LSB_TAG is defined and wide integers are used, which might
9098 happen in a future version of Emacs.
9100 2012-02-25 Chong Yidong <cyd@gnu.org>
9102 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
9105 * xselect.c (Fx_selection_exists_p): Doc fix.
9106 (x_clipboard_manager_save_all): Print an informative message
9107 before saving to clipboard manager.
9109 2012-02-24 Chong Yidong <cyd@gnu.org>
9111 * keyboard.c (process_special_events): Handle all X selection
9112 requests in kbd_buffer, not just the next one (Bug#8869).
9114 2012-02-23 Chong Yidong <cyd@gnu.org>
9116 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
9117 call when setting menu-bar-lines and tool-bar-lines parameters.
9118 (unwind_create_frame_1): New helper function.
9120 * window.c (inhibit_window_configuration_change_hook): New var.
9121 (run_window_configuration_change_hook): Obey it.
9122 (syms_of_window): Initialize it.
9124 2012-02-22 Chong Yidong <cyd@gnu.org>
9126 * xterm.c (x_draw_image_relief): Add missing type check for
9127 Vtool_bar_button_margin (Bug#10743).
9129 2012-02-21 Chong Yidong <cyd@gnu.org>
9131 * fileio.c (Vfile_name_handler_alist): Doc fix.
9133 * buffer.c (Fget_file_buffer): Protect against invalid file
9134 handler return value.
9136 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
9138 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
9139 when computing $valmask.
9141 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
9142 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
9143 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
9144 It's useless in that case, and it can cause problems on hosts
9145 that allocate halves of EMACS_INT values separately.
9146 Reported by Dan Horák. Diagnosed by Andreas Schwab in
9147 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
9148 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
9149 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
9150 it avoids undefined behavior on hosts where shifting right by more
9151 than the word width has undefined behavior.
9153 2012-02-19 Chong Yidong <cyd@gnu.org>
9155 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
9156 (Funhandled_file_name_directory, Ffile_name_as_directory)
9157 (Fdirectory_file_name, Fexpand_file_name)
9158 (Fsubstitute_in_file_name): Protect against invalid file handler
9159 return values (Bug#10845).
9161 2012-02-18 Eli Zaretskii <eliz@gnu.org>
9163 * .gdbinit (pitx): Fix incorrect references to fields of the
9166 2012-02-17 Chong Yidong <cyd@gnu.org>
9168 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
9170 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
9172 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
9173 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
9175 2012-02-15 Chong Yidong <cyd@gnu.org>
9177 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
9178 marked as special. Also, starting docstrings with * is obsolete.
9180 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
9182 * gnutls.c (emacs_gnutls_write): Fix last change.
9184 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

9189 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
9191 * keymap.c (Fsingle_key_description): Handle char ranges.
9193 2012-02-12 Chong Yidong <cyd@gnu.org>
9195 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
9196 as that creates a dangerous corner case.
9198 * window.c (Fdelete_window_internal): Invalidate the mouse
9199 highlight (Bug#9904).
9201 2012-02-12 Glenn Morris <rgm@gnu.org>
9203 * xselect.c (Fx_own_selection_internal)
9204 (Fx_get_selection_internal, Fx_disown_selection_internal)
9205 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
9206 * nsselect.m (Fx_own_selection_internal)
9207 (Fx_disown_selection_internal, Fx_selection_exists_p)
9208 (Fx_selection_owner_p, Fx_get_selection_internal):
9209 Sync docs and argument specs with the xselect.c versions.
9211 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
9213 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
9215 2012-02-11 Eli Zaretskii <eliz@gnu.org>

9231 2012-02-07 Chong Yidong <cyd@gnu.org>
9233 * buffer.c (Fbuffer_local_variables)
9234 (buffer_lisp_local_variables): Handle unbound vars correctly;
9235 don't let Qunbound leak into Lisp.
9237 2012-02-07 Glenn Morris <rgm@gnu.org>
9239 * image.c (Fimagemagick_types): Doc fix.
9241 * image.c (imagemagick-render-type): Change it from a lisp object
9242 to an integer. Move the doc here from the lisp manual.

9247 * doc.c (store_function_docstring): Avoid applying docstring of
9248 alias to base function (Bug#2603).
9250 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
9252 * .gdbinit (pp1, pv1): Remove redundant defines.
9255 2012-02-04 Chong Yidong <cyd@gnu.org>
9257 * nsterm.m: Declare a global (Bug#10694).
9259 2012-02-04 Eli Zaretskii <eliz@gnu.org>
9261 * w32.c (get_emacs_configuration_options):
9262 Include --enable-checking, if specified, in the return value.
9264 2012-02-04 Martin Rudalics <rudalics@gmx.at>
9266 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
9267 after rounding frame sizes. (Bug#9723)

9271 * keyboard.c (adjust_point_for_property): Don't position point
9272 before BEGV. (Bug#10696)
9274 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
9276 Handle overflow when computing char display width (Bug#9496).
9277 * character.c (char_width): Return EMACS_INT, not int.
9278 (char_width, c_string_width): Check for overflow when
9279 computing the width; this is possible now that individual
9280 characters can have unbounded width. Problem introduced
9281 by merge from Emacs 23 on 2012-01-19.
9283 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
9285 * dbusbind.c (Fdbus_register_method): Mention the return value

9298 2012-02-02 Kenichi Handa <handa@m17n.org>
9300 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
9301 0, do not call append_composite_glyph.
9303 2012-02-02 Kenichi Handa <handa@m17n.org>
9305 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
9307 (x_produce_glyphs): If the component of a composition is a null
9308 string, set it->pixel_width to 1 to avoid zero-width glyph.
9310 2012-02-01 Eli Zaretskii <eliz@gnu.org>
9312 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
9313 first 2 arguments are identical. This makes inserting large
9314 output from a subprocess an order of magnitude faster on
9315 MS-Windows, where all sbrk'ed memory is always contiguous.
9317 2012-01-31 Glenn Morris <rgm@gnu.org>

9845 * xdisp.c (redisplay_window): If cursor row is not fully visible
9846 after recentering, and scroll-conservatively is set to a large
9847 number, scroll window by a few more lines to make the cursor fully
9848 visible and out of scroll-margin. (Bug#10105)
9849 (start_display): Don't move to the next line if the display should
9850 start at a newline that is part of a display vector or an overlay

9930 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
9931 Otherwise, valgrind does not work on some platforms.
9932 Problem reported by Andreas Schwab in
9933 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
9934 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
9935 is set, removing the need for VIRT_ADDRESS_VARIES.
9936 (PURE_P): Use a more-efficient implementation that needs just one
9937 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
9938 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
9939 to 4 (xorl, subq, cmpq, setbe).
9940 * alloc.c (pure): Always extern now, since that's the
9941 VIRT_ADDR_VARIES behavior.
9942 (PURE_POINTER_P): Use a single comparison, not two, for
9943 consistency with the new puresize.h.
9944 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
9945 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

9952 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
9953 behave as if the cursor position were at the window margin.
9955 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
9956 and the cursor position is out of bounds, behave as if the cursor
9957 position were at the window margin. (Bug#10075)
9959 2011-11-18 Chong Yidong <cyd@gnu.org>
9961 * window.c (Fwindow_combination_limit): Make first argument

9987 * dispnew.c (verify_row_hash): Call row_hash for computing the
9988 hash code of a row, instead of duplicating code from xdisp.c.
9990 * dispextern.h (row_hash): Add prototype.
9992 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
9994 * frame.c (delete_frame): Don't delete the terminal when the last

10021 (Fset_window_configuration, save_window_save): Rename all
10022 occurrences of window_nest to window_combination_limit.
10024 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
10026 * image.c (imagemagick_load_image): Fix typo.
10028 2011-11-14 Eli Zaretskii <eliz@gnu.org>
10030 * xdisp.c (display_line): Move the call to
10031 highlight_trailing_whitespace before the call to
10032 compute_line_metrics, since the latter needs to see the final
10033 faces of all the glyphs to compute ROW's hash value.
10034 Fixes assertion violations in row_equal_p. (Bug#10035)
10036 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
10038 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

10043 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
10044 with user-defined heap size. Bump the default size of the temacs

10048 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
10049 current_matrix and desired_matrix. (Bug#9990)
10050 (verify_row_hash) [XASSERTS]: New function.

10095 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
10097 Avoid some portability problems by eschewing 'extern inline' functions.
10098 The trivial performance wins aren't worth the portability hassles; see

10107 making these static again.
10108 (offset_intervals, temp_set_point_both, temp_set_point)
10109 (copy_intervals_to_string): No longer inline.
10110 * xdisp.c (window_text_bottom_y, window_box_width)

10167 * xmenu.c (cleanup_widget_value_tree): New function.
10168 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

10175 (window_box_width, window_box_left, window_box_left_offset)
10176 (window_box_right, window_box_right_offset): Declare extern.
10177 Otherwise, these inline functions do not conform to C99 and
10178 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
10179 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
10180 * intervals.c (adjust_intervals_for_insertion)

10183 (static_offset_intervals): Remove.
10184 (offset_intervals): Rewrite using the old contents of
10185 static_offset_intervals. The old version didn't conform to C99
10186 because an extern inline function contained a reference to an

10240 (unwind_create_frame): New function (Bug#9943).
10241 (Fx_create_frame): Restructure code to be more similar to the one in
10242 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
10243 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
10244 Move terminal->reference_count++ just before making the frame official

10299 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
10300 label is not null (Bug#9951).
10301 (xg_tool_item_stale_p): Handle the fact that wimage and/or wlbl
10304 2011-11-04 Eli Zaretskii <eliz@gnu.org>
10306 * window.c (Fwindow_body_size): Mention in the doc string that the
10307 return value is in frame's canonical units. (Bug#9949)
10309 2011-11-03 Eli Zaretskii <eliz@gnu.org>
10311 * xdisp.c (note_mouse_highlight): Initialize `area'. (Bug#9947)
10313 * w32fns.c (unwind_create_frame): If needed, free the glyph
10314 matrices of the partially constructed frame. (Bug#9943)
10315 * xfns.c (unwind_create_frame): Likewise.
10317 2011-11-01 Eli Zaretskii <eliz@gnu.org>
10319 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
10320 Don't stop backward scan on the continuation glyph, even though
10321 its CHARPOS is positive.
10322 (mouse_face_from_buffer_pos, note_mouse_highlight):
10323 Rename cover_string to disp_string.
10325 2011-11-01 Martin Rudalics <rudalics@gmx.at>
10327 * window.c (temp_output_buffer_show): Don't use
10328 Vtemp_buffer_show_specifiers.
10329 (Vtemp_buffer_show_specifiers): Remove unused variable.
10331 2011-10-30 Eli Zaretskii <eliz@gnu.org>
10333 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
10334 past the beginning of the current glyph matrix.
10336 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
10338 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
10339 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
10340 HAVE_GTK3 (Bug#9869).
10342 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
10343 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
10345 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
10347 * xterm.c: Declare x_handle_net_wm_state to return int.
10348 (handle_one_xevent): Check if we are iconified but don't have
10349 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
10350 (get_current_wm_state): Return non-zero if not hidden,
10351 check for _NET_WM_STATE_HIDDEN (Bug#9893).

10356 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
10358 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
10359 so that this new function doesn't get optimized away by a
10360 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
10362 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
10364 * frame.h (MOUSE_HL_INFO): Remove excess parens.
10366 2011-10-29 Eli Zaretskii <eliz@gnu.org>
10368 Fix the `xbytecode' command.
10369 * .gdbinit (xprintbytestr): New command.
10370 (xwhichsymbols): Rename from `which'; all callers changed.
10371 (xbytecode): Print the byte-code string as well.
10373 2011-10-29 Kim Storm <storm@cua.dk>
10375 * alloc.c (which_symbols): New function.
10377 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
10379 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
10382 2011-10-29 Glenn Morris <rgm@gnu.org>
10384 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
10385 Not clear what it was for, and it causes various bugs. (Bug#9839)
10387 2011-10-28 Eli Zaretskii <eliz@gnu.org>
10389 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
10390 possible random value that matches one of those tested as
10391 condition to clear the mouse face.
10393 2011-10-28 Chong Yidong <cyd@gnu.org>
10395 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
10397 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
10399 * window.c (make_window): Initialize phys_cursor_on_p.
10401 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
10403 * lisp.h (struct Lisp_Symbol): Update comments.
10405 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
10407 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
10409 2011-10-28 Eli Zaretskii <eliz@gnu.org>
10411 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
10412 <oslsachem@gmail.com> for helping to debug this.
10414 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
10415 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
10416 (g_b_init_get_glyph_outline_w): New static variables.
10417 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
10418 (GetGlyphOutlineW_Proc): New typedefs.
10419 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
10420 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
10422 (w32font_open_internal, compute_metrics):
10423 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
10424 instead of calling the "wide" APIs directly.
10426 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
10428 * w32.h (syms_of_w32font): Add prototype.
10430 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
10432 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
10433 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
10434 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
10435 (Fmove_to_window_line): Doc fix.
10437 2011-10-27 Chong Yidong <cyd@gnu.org>
10439 * process.c (make_process): Set gnutls_state to NULL.
10441 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
10442 non-NULL, regardless of GNUTLS_INITSTAGE.
10443 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
10444 an error. Set process slots as soon as we allocate them.
10446 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
10448 2011-10-27 Chong Yidong <cyd@gnu.org>
10450 * gnutls.c (emacs_gnutls_deinit): New function.
10451 Deallocate credentials structures as well as calling gnutls_deinit.
10452 (Fgnutls_deinit, Fgnutls_boot): Use it.
10454 * process.c (make_process): Initialize GnuTLS credentials to NULL.
10455 (deactivate_process): Call emacs_gnutls_deinit.
10457 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
10459 * image.c (x_create_x_image_and_pixmap):
10460 * w32.c (sys_rename, w32_delayed_load):
10461 * w32font.c (fill_in_logfont):
10462 * w32reg.c (x_get_string_resource): Silence compiler warnings.
10464 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
10466 * w32fns.c (w32_default_color_map): New function,
10467 extracted from Fw32_default_color_map.
10468 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
10470 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
10472 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
10474 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
10476 * keyboard.c (test_undefined): New function (bug#9751).
10477 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
10479 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
10481 * sysdep.c (init_sys_modes): Fix the check for the controlling
10482 terminal (Bug#6649).
10484 2011-10-20 Eli Zaretskii <eliz@gnu.org>
10486 * dispextern.h (struct bidi_it): New member next_en_type.
10488 * bidi.c (bidi_line_init): Initialize the next_en_type member.
10489 (bidi_resolve_explicit_1): When next_en_pos is valid for the
10490 current character, check also for next_en_type being WEAK_EN.
10491 (bidi_resolve_weak): Don't enter the expensive loop if the current
10492 position is before next_en_pos. Record the bidi type of the first
10493 non-ET, non-BN character we find, in addition to its position.
10494 (bidi_level_of_next_char): Invalidate next_en_type when
10495 next_en_pos is over-stepped.
10497 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
10499 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
10500 * editfns.c: Rewrite current-time-zone so that it invokes
10501 the equivalent of (format-time-string "%Z") to get the time zone name.
10502 This fixes a bug when the time zone name contains characters that
10503 need converting from the system time locale to Emacs internal format.
10504 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
10505 that patch fixed format-time-string to do the conversion, but
10506 I forgot to fix current-time-zone.
10507 (format_time_string): New function, containing most of
10508 what Fformat_time_string used to contain.
10509 (Fformat_time_string): Rewrite in terms of format_time_string.
10510 This doesn't change this function's behavior.
10511 (current-time-zone): Rewrite to use format_time_string.
10512 This fixes the bug reported by Michael Schierl in
10513 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
10514 Jason Rumney's 2007-06-07 change worked around this bug, but
10516 * systime.h (tzname, timezone): Remove no-longer-used declarations.
10518 2011-10-19 Eli Zaretskii <eliz@gnu.org>
10520 * xdisp.c (start_display): If the character at POS is displayed
10521 via a display vector, reset IT->current.dpvec_index to zero.
10522 (try_window_reusing_current_matrix): If a line ends in a display
10523 vector or the next line starts in a display vector, continue
10524 redrawing the window even though the character position of
10525 start_row was reached.
10528 2011-10-18 Chong Yidong <cyd@gnu.org>
10530 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
10531 with nobreak-char-display too.
10533 2011-10-18 Eli Zaretskii <eliz@gnu.org>
10535 Fix part 3 of bug#9771.
10536 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
10537 (bidi_resolve_neutral): Don't enter the expensive loop looking for
10538 non-neutral characters if the current character is a paragraph
10539 separator (a.k.a. Newline). This avoids running the same
10540 expensive loop twice, once when we consume the preceding newline
10541 and the other time when the line actually needs to be displayed.
10542 Avoid the loop when we see neutrals on the base embedding level
10543 following a character whose directionality is the same as the
10544 paragraph's. This avoids running the expensive loop when a line
10545 ends in a long sequence of neutrals, like control characters.
10546 Add assertion against STRONG_AL type. Slightly rearrange code
10547 that determines the type of a neutral given the first non-neutral
10549 (bidi_level_of_next_char): Set next_en_pos to zero when
10550 invalidating its info.
10552 2011-10-17 Eli Zaretskii <eliz@gnu.org>
10554 * xdisp.c (push_display_prop): Determine whether to record string
10555 or buffer position by IT->string, not by IT->method. Allow
10556 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
10557 (move_it_vertically_backward): Don't look for character position
10558 immediately after the newline when in a continuation line.
10561 2011-10-15 Martin Rudalics <rudalics@gmx.at>
10563 * window.c (coordinates_in_window): Rewrite and delabelize
10564 vertical border check. (Bug#5357) (Bug#9618)
10566 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
10568 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
10569 errors in XSetWindowBorder (bug#9310).
10571 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
10573 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
10574 avoid crash when xmalloc overrun checking is enabled.
10576 2011-10-13 Eli Zaretskii <eliz@gnu.org>
10578 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
10579 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
10580 cursor motion with <left> and <right> arrow keys.
10582 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
10583 some callers set that themselves.
10585 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10587 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
10588 display string and the previous row comes from the same string and
10589 is empty. (Bug#9739) (Bug#9738)
10591 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
10593 * doc.c (get_doc_string): Encode file name (bug#9735).
10595 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10597 * bidi.c (bidi_level_of_next_char):
10598 * xdisp.c (get_visually_first_element): Remove old incorrect
10599 comments regarding the Unicode Line Separator character.
10601 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
10603 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
10605 * alloc.c (Fgc_status): Do not access beyond zombies array
10606 boundary if nzombies > MAX_ZOMBIES.
10607 * alloc.c (dump_zombies): Add missing format specifier.
10609 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
10611 * xdisp.c (set_cursor_from_row): Simplify conditionals,
10612 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
10614 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
10615 Some packages use them to denote characters with modifiers.
10617 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
10619 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
10620 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
10621 matching a pp-number. Rename parameter var to var1.
10623 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
10625 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
10627 2011-10-08 Glenn Morris <rgm@gnu.org>
10629 * callint.c (Fcall_interactively): Give a more explicit error for the
10630 'c' case with a non-character input. (Bug#8479)
10632 2011-10-08 Eli Zaretskii <eliz@gnu.org>
10634 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
10636 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
10637 lines that are hscrolled on the left.
10639 * dispnew.c (buffer_posn_from_coords): Account for a possible
10640 presence of header-line. (Bug#4426)
10642 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
10644 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
10645 Don't advertise functionality which we discourage or doesn't work.
10647 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
10649 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
10650 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
10651 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
10652 this makes Emacs dump core during garbage collection on rare
10653 occasions. sizeof is obviously inferior to offsetof here, so
10654 stick with offsetof.
10655 (GC_POINTER_ALIGNMENT): New macro.
10656 (mark_memory): Omit 3rd (offset) arg; caller changed.
10657 Don't assume EMACS_INT alignment is the same as pointer alignment.
10659 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
10661 * keyboard.c (read_key_sequence_remapped): New var.
10662 (read_key_sequence): Compute remapping in the right buffer.
10663 (command_loop_1): Use read_key_sequence's remapping directly.
10665 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
10667 * dired.c (file_name_completion): Don't expand file name.
10668 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
10669 before checking file name handler.
10671 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
10672 they've been requested explicitly (bug#9591).
10674 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
10676 * keymap.c (Fsingle_key_description): Use make_specified_string
10677 instead of build_string to build string from push_key_description.
10680 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10682 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
10683 This fixes a Y2038 bug on 64-bit hosts.
10684 * buffer.c (reset_buffer):
10685 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
10686 (Fclear_buffer_auto_save_failure):
10687 Use 0, not -1, to represent an unset failure time, since time_t
10688 might not be signed.
10690 Remove dependency on glibc malloc internals.
10691 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10692 Move back here from lisp.h, but with their new implementations.
10693 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10694 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
10695 * charset.c (charset_table_init): New static var.
10696 (syms_of_charset): Use it instead of xmalloc. This removes a
10697 dependency on glibc malloc internals. See Eli Zaretskii's comment in
10698 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
10699 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10700 Move back to alloc.c.
10701 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10702 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
10704 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
10706 * nsterm.m (windowDidResize): Call x_set_window_size only when
10707 ns_in_resize is true. Otherwise set pixelwidth/height and
10708 call change_frame_size (Bug#9628).
10710 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10712 Port --enable-checking=all to Fedora 14 x86-64.
10713 * charset.c (syms_of_charset): Also account for glibc malloc's
10714 internal overhead when calculating the initial malloc maximum.
10716 Port --enable-checking=all to Fedora 14 x86.
10717 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10719 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
10720 (overrun_check_realloc, overrun_check_free):
10721 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
10722 That way, xmalloc returns a properly-aligned pointer even if
10723 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
10724 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
10725 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
10726 into account when calculating the initial malloc maximum.
10727 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10728 Move here from alloc.c, so that charset.c can use it too.
10729 Properly align; the old code wasn't right for common 32-bit hosts
10730 when configured with --enable-checking=all.
10731 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10732 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
10734 2011-09-29 Eli Zaretskii <eliz@gnu.org>
10736 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
10739 2011-09-28 Eli Zaretskii <eliz@gnu.org>
10741 * xdisp.c (compute_display_string_end): If there's no display
10742 string at CHARPOS, return -1.
10744 * bidi.c (bidi_fetch_char): When compute_display_string_end
10745 returns a negative value, treat the character as a normal
10746 character not covered by a display string. (Bug#9624)
10748 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
10750 * lread.c (Fread_from_string): Fix typo in docstring.
10752 2011-09-27 Eli Zaretskii <eliz@gnu.org>
10754 * xdisp.c (handle_invisible_prop): If invisible text ends on a
10755 newline, reseat the iterator instead of bidi-iterating there one
10756 character at a time. (Bug#9610)
10757 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
10758 TO_CHARPOS if the bidi iterator is at base embedding level.
10760 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
10762 * lread.c (readevalloop): Use correct code for NBSP.
10763 (read1): Likewise. (Bug#9608)
10765 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
10767 * dbusbind.c (Fdbus_register_signal): When service is not

10770 2011-09-25 Glenn Morris <rgm@gnu.org>
10772 * buffer.c (truncate-lines): Doc fix.
10774 2011-09-24 Chong Yidong <cyd@stupidchicken.com>

10792 Default value is now t. Doc fix.
10794 * indent.c (Fvertical_motion): Compute and apply the overshoot
10795 logic when moving up, not only when moving down. Fix the
10796 confusing name and values of the it_overshoot_expected variable;
10797 logic changes accordingly. (Bug#9254) (Bug#9549)
10799 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
10800 CHARPOS is covered by a display string which includes newlines.
10801 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
10802 is covered by a display string with embedded newlines.
10804 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
10806 * dbusbind.c (Fdbus_register_signal): Add match rule to
10807 Vdbus_registered_objects_table. (Bug#9581)
10808 (Fdbus_register_method, Vdbus_registered_objects_table):
10811 2011-09-24 Jim Meyering <meyering@redhat.com>
10813 do not ignore write error for any output size
10814 The previous change was incomplete.
10815 While it makes emacs --batch detect the vast majority of stdout
10816 write failures, errors were still ignored whenever the output size is
10817 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
10818 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
10819 && echo FAIL: ignored write error
10820 FAIL: ignored write error
10821 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
10822 && echo FAIL: ignored write error
10823 FAIL: ignored write error
10824 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
10826 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
10828 * emacs.c (Fkill_emacs): In noninteractive mode exit
10829 non-successfully if a write error occurred on stdout. (Bug#9574)
10831 2011-09-21 Eli Zaretskii <eliz@gnu.org>
10833 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
10836 * dispextern.h (struct it): Update the comment documenting what
10839 2011-09-20 Eli Zaretskii <eliz@gnu.org>
10841 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
10842 a display string, extend search for cursor position to end of row.
10843 (find_row_edges): If the row ends in a newline from a display
10844 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
10845 Handle the case of a display string with multiple newlines.
10846 (Fcurrent_bidi_paragraph_direction): Fix search for previous
10847 non-empty line. Fixes confusing cursor motion with arrow keys at
10848 the beginning of a line that starts with whitespace.
10850 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
10852 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
10855 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
10857 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
10858 boolean (Bug#9154).
10860 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10862 * xdisp.c (display_line): Record maximum and minimum buffer
10863 positions even if no glyphs were produced (e.g., by a zero-width
10864 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
10865 buffer positions that will be removed from the glyph row because
10867 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
10868 column is beyond frame width: don't subtract 1 "pixel" when
10869 computing width of the stretch.
10870 (reseat_at_next_visible_line_start): Undo the change made on
10871 2011-09-17 that saved paragraph information and restored it after
10872 the call to `reseat'. (Bug#9545)
10874 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10876 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
10877 and turn window cursor on if cleared (Bug#9415).
10879 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
10881 * search.c (boyer_moore): Take unibyte characters from pattern
10882 literally. (Bug#9458)

10899 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10901 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
10903 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10905 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
10906 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
10908 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10910 * xdisp.c (reseat_at_next_visible_line_start): Keep information
10911 about the current paragraph and restore it after the call to reseat.
10913 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
10914 (bidi_find_paragraph_start): Search back for paragraph beginning
10915 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
10916 (bidi_move_to_visually_next): Only trigger paragraph-related
10917 computations when the last character is a newline or at EOB, not
10918 just any NEUTRAL_B. (Bug#9470)
10920 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
10921 truncated lines if point is covered by a display string. (Bug#9524)
10923 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
10925 * xselect.c: Relax test for outgoing X longs (Bug#9498).
10926 (cons_to_x_long): New function.
10927 (lisp_data_to_selection_data): Use it. Correct the test for
10928 short-versus-long data; it was negated. Break out of vector
10929 loop, for efficiency, when a long datum is discovered.
10931 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
10933 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
10935 2011-09-16 Eli Zaretskii <eliz@gnu.org>
10937 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
10938 GCC PR/17406) by declaring this function with external scope.
10940 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10942 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
10943 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
10945 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
10947 * editfns.c (Fformat): Correctly handle text properties on "%%".

10957 of TAB characters in a composition.
10959 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10961 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
10962 This occurs when processing a multibyte format.
10963 Problem reported by Wolfgang Jenker.
10965 2011-09-15 Johan Bockgård <bojohan@gnu.org>
10967 * xdisp.c (try_cursor_movement): Only check for exact match if
10968 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
10970 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10972 Remove unused external symbols.
10973 * dispextern.h (calc_pixel_width_or_height): Remove decl.
10974 * xdisp.c (calc_pixel_width_or_height): Now static.
10975 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.

10977 * w32term.c: Fix comment to match code.
10978 * xterm.c, xterm.h (x_catching_errors): Remove.
10980 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10982 * xselect.c: Use signed conversions more consistently (Bug#9498).
10983 (selection_data_to_lisp_data): Assume incoming selection data are
10984 signed integers, not unsigned. This is to be consistent with
10985 outgoing selection data, which was modified to use signed integers
10986 in as part of the fix to Bug#9196 in response to Jan D.'s comment
10987 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
10988 expects long, not unsigned long.
10990 2011-09-14 Eli Zaretskii <eliz@gnu.org>
10992 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
10993 computation of loop end. Reported by Johan Bockgård
10996 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
10998 * frame.c (Fother_visible_frames_p): Function deleted.
11000 2011-09-12 Eli Zaretskii <eliz@gnu.org>
11002 * indent.c (compute_motion): Process display vector front to back
11003 rather than the other way around. (Bug#2496)
11005 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
11007 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
11009 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
11011 * minibuf.c (Fread_from_minibuffer): Doc fix.
11013 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11015 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
11016 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
11018 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
11020 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
11021 value for non-existent files.
11023 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11025 * fileio.c (Finsert_file_contents): If the file cannot be opened,
11026 set its "size" to -1. This will set the modtime_size field of
11027 the corresponding buffer to -1, which is what
11028 verify-visited-file-modtime expects for files that do not exist.
11031 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
11033 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
11035 * lisp.h: ... from here. push_key_description is no longer
11036 defined in keyboard.c, so its declaration should not be in
11037 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
11038 logically belongs with push_key_description.
11040 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
11042 * buffer.h: Include <sys/types.h> instead of <time.h>.
11043 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
11044 Problem reported by Herbert J. Skuhra.
11046 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
11048 * xml.c (parse_region): Make the parsing work for
11049 non-comment-starting XML files again (bug#9144).
11051 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
11053 * image.c (gif_load): Fix calculation of bottom and right corner.
11056 2011-09-10 Eli Zaretskii <eliz@gnu.org>
11058 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
11059 redisplay in small windows.
11061 2011-09-09 Eli Zaretskii <eliz@gnu.org>
11063 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
11065 2011-09-08 Martin Rudalics <rudalics@gmx.at>
11067 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
11068 Operate on live windows only.
11070 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
11072 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
11074 2011-09-07 Eli Zaretskii <eliz@gnu.org>
11076 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
11077 only under bidi iteration.
11079 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
11081 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
11083 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11085 isnan: Fix porting problem to Solaris 10 with bundled gcc.
11086 Without this fix, the command to link temacs failed due to an
11087 undefined symbol __builtin_isnan. This is because
11088 /usr/include/iso/math_c99.h #defines isnan(x) to
11089 __builtin_isnan(x), but the bundled gcc, which identifies itself
11090 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
11092 * floatfns.c (isnan): #undef, and then #define to a clone of
11094 (Fisnan): Always define, since it's always available now.
11095 (syms_of_floatfns): Always define isnan at the Lisp level.
11097 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11099 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
11101 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11103 * fileio.c: Fix bugs with large file offsets (Bug#9428).
11104 The previous code assumed that file offsets (off_t values) fit in
11105 EMACS_INT variables, which is not true on typical 32-bit hosts.
11106 The code messed up by falsely reporting buffer overflow in cases
11107 such as (insert-file-contents "big" nil 1 2) into an empty buffer
11108 when "big" contains more than 2**29 bytes, even though this
11109 inserts just one byte and does not overflow the buffer.
11110 (Finsert_file_contents): Store file offsets as off_t
11111 values, not as EMACS_INT values. Check for overflow when
11112 converting between EMACS_INT and off_t. When checking for
11113 buffer overflow or for overlap, take the offsets into account.
11114 Don't use EMACS_INT for small values where int suffices.
11115 When checking for overlap, fix a typo: ZV was used where
11116 ZV_BYTE was intended.
11117 (Fwrite_region): Don't assume off_t fits into 'long'.
11118 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
11120 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
11122 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
11124 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
11126 sprintf-related integer and memory overflow issues (Bug#9412).
11128 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
11129 (esprintf, exprintf, evxprintf): New functions.
11130 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
11131 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
11132 (modify_event_symbol): Do not assume that the length of
11133 name_alist_or_stem is safe to alloca and fits in int.
11134 (Fexecute_extended_command): Likewise for function name and binding.
11135 (Frecursion_depth): Wrap around reliably on integer overflow.
11136 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
11137 since some callers pass EMACS_INT values.
11138 (Fsingle_key_description): Don't crash if symbol name contains more
11139 than MAX_ALLOCA bytes.
11140 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
11141 (get_minibuffer): Arg is now EMACS_INT, not int.
11142 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
11143 (esprintf, exprintf, evxprintf): New decls.
11144 * window.h (command_loop_level, minibuf_level): Reflect API changes.
11146 * dbusbind.c (signature_cat): New function.
11147 (xd_signature, Fdbus_register_signal):
11148 Do not overrun buffer; instead, report string overflow.
11150 * dispnew.c (add_window_display_history): Don't overrun buffer.
11151 Truncate instead; this is OK since it's just a log.
11153 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
11154 even if the time zone offset is outlandishly large.
11155 Don't mishandle offset == INT_MIN.
11157 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
11158 when creating daemon; the previous buffer-overflow check was incorrect.
11160 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
11161 which has the guts of the old verror function.
11163 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
11164 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
11166 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
11167 (font_unparse_xlfd): Don't blindly alloca long strings.
11168 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
11169 fits in int, when using sprintf. Use single snprintf to count
11170 length of string rather than counting it via multiple sprintfs;
11171 that's simpler and more reliable.
11172 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
11173 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
11174 sprintf, in case result does not fit in int.
11176 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
11177 (fontset_from_font): Print it.
11179 * frame.c (tty_frame_count): Now printmax_t, not int.
11180 (make_terminal_frame, set_term_frame_name): Print it.
11181 (x_report_frame_params): In X, window IDs are unsigned long,
11182 not signed long, so print them as unsigned.
11183 (validate_x_resource_name): Check for implausibly long names,
11184 and don't assume name length fits in 'int'.
11185 (x_get_resource_string): Don't blindly alloca invocation name;
11186 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
11189 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
11190 (xg_check_special_colors, xg_set_geometry):
11191 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
11193 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
11194 Use esprintf, not sprintf, in case result does not fit in int.
11196 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11197 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
11198 it as a large positive number.
11199 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
11200 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11202 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
11203 in case result does not fit in int.
11205 * print.c (float_to_string): Detect width overflow more reliably.
11206 (print_object): Make sprintf buffer a bit bigger, to avoid potential
11207 buffer overrun. Don't assume list length fits in 'int'. Treat
11208 print length of 0 as 0, not as infinity; to be consistent with other
11209 uses of print length in this function. Don't overflow print length
11210 index. Don't assume hash table size fits in 'long', or that
11211 vectorlike size fits in 'unsigned long'.
11213 * process.c (make_process): Use printmax_t, not int, to format
11214 process-name gensyms.
11216 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
11218 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
11219 to avoid potential buffer overrun.
11221 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
11222 if X resource line is longer than 512 bytes.
11224 * xfns.c (x_window): Make sprintf buffer a bit bigger
11225 to avoid potential buffer overrun.
11227 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
11229 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
11231 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
11233 Integer overflow fixes for scrolling, etc.
11234 Without these, Emacs silently mishandles large integers sometimes.
11235 For example, "C-u 4294967297 M-x recenter" was treated as if
11236 it were "C-u 1 M-x recenter" on a typical 64-bit host.
11238 * xdisp.c (try_window_id): Check Emacs fixnum range before
11239 converting to 'int'.
11241 * window.c (window_scroll_line_based, Frecenter):
11242 Check that an Emacs fixnum is in range before assigning it to 'int'.
11243 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
11244 values converted from Emacs fixnums.
11245 (Frecenter): Don't wrap around a line count if it is out of 'int'
11246 range; instead, treat it as an extreme value.
11247 (Fset_window_configuration, compare_window_configurations):
11248 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
11250 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
11251 that can exceed INT_MAX. Check that EMACS_INT value is in range
11252 before assigning it to the (possibly-narrower) index.
11253 (match_limit): Don't assume that a fixnum can fit in 'int'.
11255 * print.c (print_object): Use ptrdiff_t, not int, for index that can
11258 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
11259 (Fvertical_motion): Don't wrap around LINES values that don't fit
11260 in 'int'. Instead, treat them as extreme values. This is good
11261 enough for windows, which can't have more than INT_MAX lines anyway.
11263 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
11265 * Require libxml/parser.h to avoid compilation warning.
11267 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
11269 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
11270 since this reportedly can destroy thread storage.
11272 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
11274 * syntax.c (find_defun_start): Update all cache variables if
11275 exiting early (Bug#9401).
11277 2011-08-30 Eli Zaretskii <eliz@gnu.org>
11279 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
11281 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
11282 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
11283 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
11285 * term.c (tty_append_glyph): New function.
11286 (produce_stretch_glyph): Static function and its prototype deleted.
11288 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
11291 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
11293 * image.c (parse_image_spec): Check for nonnegative, not for positive,
11294 when checking :margin (Bug#9390).
11295 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
11296 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
11297 so that the name doesn't mislead. All uses changed.
11299 2011-08-28 Johan Bockgård <bojohan@gnu.org>
11301 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
11304 2011-08-27 Eli Zaretskii <eliz@gnu.org>
11306 * xdisp.c (move_it_to): Don't bail out early when reaching
11307 position beyond to_charpos, if we are scanning backwards.
11308 (move_it_vertically_backward): When DY == 0, make sure we get to
11309 the first character in the line after the newline.
11311 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
11313 * ccl.c: Improve and simplify overflow checking (Bug#9196).
11314 (ccl_driver): Do not generate an out-of-range pointer.
11315 (Fccl_execute_on_string): Remove unnecessary check for
11316 integer overflow, noted by Stefan Monnier in
11317 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
11318 Remove a FIXME that didn't need fixing.
11319 Simplify the newly-introduced buffer reallocation code.
11321 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
11323 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
11325 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
11327 Integer and memory overflow issues (Bug#9196).
11329 * doc.c (get_doc_string): Rework so that
11330 get_doc_string_buffer_size is the actual buffer size, rather than
11331 being 1 less than the actual buffer size; this makes xpalloc more
11334 * image.c (x_allocate_bitmap_record, cache_image):
11335 * xselect.c (Fx_register_dnd_atom):
11336 Simplify previous changes by using xpalloc.
11338 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
11339 since either will do and ptrdiff_t is convenient with xpalloc.
11341 * charset.c (charset_table_size)
11342 (struct charset_sort_data.priority): Now ptrdiff_t.
11343 (charset_compare): Don't overflow if priorities differ greatly.
11344 (Fsort_charsets): Don't assume list length fits in int.
11345 Check for size-calculation overflow when allocating sort data.
11346 (syms_of_charset): Allocate an initial charset table that is
11347 just under 64 KiB, to avoid problems with glibc malloc and mmap.
11349 * cmds.c (internal_self_insert): Check for size-calculation overflow.
11351 * composite.h (struct composition.glyph_len): Now int, not unsigned.
11352 The actual value is always <= INT_MAX, and leaving it unsigned made
11353 overflow checking harder.
11355 * dispextern.h (struct glyph_matrix.rows_allocated)
11356 (struct face_cache.size): Now ptrdiff_t, for convenience in use
11357 with xpalloc. The values are still always <= INT_MAX.
11359 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
11361 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
11362 (SAFE_NALLOCA): New macro.
11364 * region-cache.c (struct boundary.pos, find_cache_boundary)
11365 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
11366 (set_cache_region, invalidate_region_cache)
11367 (revalidate_region_cache, know_region_cache, region_cache_forward)
11368 (region_cache_backward, pp_cache):
11369 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
11370 so that ptrdiff_t * can be passed to xpalloc.
11371 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
11372 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
11373 (pp_cache): Don't assume cache_len fits in int.
11374 * region-cache.h: Adjust extern decls to match.
11376 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
11377 EMACS_INT, since either will do, for xpalloc.
11379 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
11380 (xnmalloc, xnrealloc, xpalloc): New functions.
11382 * bidi.c (bidi_shelve_header_size): New constant.
11383 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
11384 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
11386 * bidi.c (bidi_cache_shrink):
11387 * buffer.c (overlays_at, overlays_in, record_overlay_string)
11389 Don't update size of array until after memory allocation succeeds,
11390 because xmalloc/xrealloc may not return.
11391 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
11392 now that we have proper integer overflow checking.
11393 (record_overlay_string, overlay_strings): Catch overflows when
11394 calculating size of overlay_str_buf.
11396 * callproc.c (Fcall_process): Check for size overflow when
11397 calculating size of args2.
11398 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
11399 Normally we prefer signed values, but sticking with ptrdiff_t would
11400 require adding more-complicated checks.
11402 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
11403 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
11404 Redo buffer-overflow calculations to avoid integer overflow.
11405 Add a FIXME comment where memory seems to be over-allocated.
11407 * character.c (Fstring): Check for size-calculation overflow.
11409 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
11410 unnecessary integer overflow. Check for size overflow.
11411 (encode_coding_object): Don't update size until xmalloc succeeds.
11413 * composite.c (get_composition_id): Check for overflow in glyph
11414 length calculations.
11416 Integer and memory overflow fixes for display code.
11417 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
11418 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
11419 (scrolling_window): Check for overflow in size calculations.

11423 (row_table_size): Now ptrdiff_t, not int.
11424 (scrolling_window): Avoid overflow in size calculations.
11425 Don't update size until allocation succeeds.
11426 * fns.c (concat): Check for overflow in size calculations.
11427 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
11428 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

11431 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
11432 (get_doc_string): Check for size calculation overflow.
11433 Don't update size until allocation succeeds.
11434 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
11435 EMACS_INT, where ptrdiff_t will do.
11436 (Fsubstitute_command_keys): Check for string overflow.
11438 * editfns.c (set_time_zone_rule): Don't assume environment length
11440 (message_length): Now ptrdiff_t, not int.
11441 (Fmessage_box): Don't update size until allocation succeeds.
11442 Don't assume message length fits in int.
11443 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
11445 * emacs.c (main): Do not reallocate argv, since there is a null at
11446 the end that can be overwritten, and this way there's no need to
11447 worry about size-calculation overflow.
11448 (sort_args): Check for size-calculation overflow.
11450 * eval.c (init_eval_once, grow_specpdl): Don't update size until
11452 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
11454 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
11455 (x_set_scroll_bar_width, x_figure_window_size):
11456 Check for integer overflow.
11457 (x_set_alpha): Do not assume XINT fits in int.
11459 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
11460 This is for the members text_lines, text_cols, total_lines, total_cols,
11461 where the system imposes an 'int' limit.
11463 * fringe.c (Fdefine_fringe_bitmap):
11464 Don't update size until alloc works.
11466 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
11467 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
11469 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
11470 Check for size-calculation overflow.
11471 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
11472 do, as we prefer signed integers.
11473 (id_to_widget.max_size, id_to_widget.used)
11474 (xg_store_widget_in_map, xg_remove_widget_from_map)
11475 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
11476 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
11477 Use and return ptrdiff_t, not int.
11478 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
11479 * gtkutil.h: Change prototypes to match the above.
11481 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
11482 are duplicate now that they've been promoted to lisp.h.
11483 (x_allocate_bitmap_record, x_alloc_image_color)
11484 (make_image_cache, cache_image, xpm_load):
11485 Don't update size until alloc is done.
11486 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
11488 Check for size calculation overflow.
11489 (ct_colors_allocated_max): New constant.
11490 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
11493 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
11494 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
11495 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
11496 Use ptrdiff_t, not int, to count maps.
11497 (read_char_minibuf_menu_prompt): Check for overflow in size
11498 calculations. Don't update size until allocation succeeds.
11499 Redo calculations to avoid overflow.
11500 * keyboard.h: Change prototypes to match the above.
11502 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
11504 (current_minor_maps): Check for size calculation overflow.
11505 * keymap.h: Change prototypes to match the above.
11507 * lread.c (read1, init_obarray): Don't update size until alloc done.
11509 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
11510 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
11512 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
11513 Now ptrdiff_t, not int.
11514 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

11526 (Fset_match_data): Don't assume list lengths fit in 'int'.
11528 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
11529 for command line length. Do not attempt to address one before the
11530 beginning of an array, as that's not portable.
11532 * term.c (max_frame_lines): Remove; unused.
11533 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
11535 (encode_terminal_code, calculate_costs): Check for size
11536 calculation overflow.

11539 done. Redo calculations to avoid overflow.
11540 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
11542 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
11543 subtracting pointers.
11544 (gobble_line): Check for overflow more carefully. Don't update size
11547 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.

11558 Use ptrdiff_t, not int, for sizes.
11559 (Finternal_make_lisp_face, cache_face):
11560 Check for size calculation overflow.
11561 (cache_face): Treat size calculation overflows as if they were
11562 memory exhaustion (the usual treatment), rather than aborting.
11564 * xfns.c (x_encode_text, x_set_name_internal)
11565 (Fx_change_window_property): Use ptrdiff_t, not int, to count
11566 sizes, since they can exceed INT_MAX in size. Check for size
11567 calculation overflow.
11569 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
11570 (xg_select): Check for size calculation overflow.
11571 Don't update size until alloc done.
11573 * xrdb.c (get_environ_db): Don't assume path length fits in int,
11574 as sprintf is limited to int lengths.
11576 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
11577 (X_LONG_MIN): New macros.
11578 Use them to make the following changes clearer.
11579 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
11580 This change doesn't affect the value now, but it may help remind
11581 future maintainers not to raise the value too much later.
11582 (SELECTION_QUANTUM): Remove, replacing with ...
11583 (selection_quantum): ... new function, which avoids overflow.
11585 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
11586 assumption that selection length fits in 'int'.
11587 (x_reply_selection_request, x_handle_selection_request)
11588 (x_get_window_property, receive_incremental_selection)
11589 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
11590 (lisp_data_to_selection_data, clean_local_selection_data):

11592 (x_reply_selection_request, x_get_window_property)
11593 (receive_incremental_selection, x_property_data_to_lisp):
11594 Redo calculations to avoid overflow.
11595 (x_reply_selection_request): When sending hint, ceiling it at
11596 X_LONG_MAX rather than relying on wraparound overflow to send
11598 (x_get_window_property, receive_incremental_selection)
11599 (lisp_data_to_selection_data, x_property_data_to_lisp):
11600 Check for size-calculation overflow.
11601 (x_get_window_property, receive_incremental_selection)
11602 (lisp_data_to_selection_data, Fx_register_dnd_atom):
11603 Don't store size until memory allocation succeeds.
11604 (x_get_window_property): Plug memory leak on memory exhaustion.
11605 Don't double-block input; malloc is safe here. Don't assume 2**34
11606 - 4 fits in unsigned long. Add an xassert to check
11607 XGetWindowProperty overflow. Be more careful about overflow
11608 calculations, and distinguish size from memory overflow better.
11609 (receive_incremental_selection): When tracing, don't assume
11610 unsigned int is less than INT_MAX.
11611 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
11612 harmful) conversions of unsigned short to int.
11613 (lisp_data_to_selection_data): Don't assume that integers
11614 in the range -65535 through -1 fit in an X unsigned short.
11615 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
11616 result parameters unless successful. Rely on cons_to_unsigned
11617 to report problems with elements; the old code wasn't right anyway.
11618 (x_check_property_data): Check for int overflow; we cannot use
11619 a wider type due to X limits.
11620 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
11622 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

11651 * image.c (xpm_get_color_table_h):
11652 * lisp.h (hash_lookup, hash_put):
11653 * minibuf.c (Ftest_completion):
11654 Use ptrdiff_t for hash table indexes, not int (which is too
11655 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
11656 32-bit --with-wide-int hosts).
11658 * charset.c (Fdefine_charset_internal): Check for integer overflow.
11659 Add a FIXME comment about memory leaks.
11660 (syms_of_charset): Don't assume xmalloc returns.
11662 Don't assume that stated character widths fit in int.
11663 * character.c (Fchar_width, c_string_width, lisp_string_width):
11664 * character.h (CHAR_WIDTH):
11665 * indent.c (MULTIBYTE_BYTES_WIDTH):
11666 Use sanitize_char_width to avoid undefined and/or bad behavior
11667 with outlandish widths.
11668 * character.h (sanitize_tab_width): Rename from sanitize_width,
11669 now that we have two such functions. All uses changed.
11670 (sanitize_char_width): New inline function.
11672 Don't assume that tab-width fits in int.
11673 * character.h (sanitize_width): New inline function.
11674 (SANE_TAB_WIDTH): New macro.
11675 (ASCII_CHAR_WIDTH): Use it.

11681 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
11683 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
11684 Remove unreachable code.
11685 (read_hex, load_charset_map_from_file): Check for integer overflow.
11687 * xterm.c: Don't go over XClientMessageEvent limit.
11688 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
11689 (x_send_scroll_bar_event): Likewise. Check that the size does not
11690 exceed limits imposed by XClientMessageEvent, as well as the usual
11691 ptrdiff_t and size_t limits.
11693 * keyboard.c: Overflow, signedness and related fixes.
11694 (make_lispy_movement): Use same integer type in forward decl
11695 that is used in the definition.
11696 (read_key_sequence, keyremap_step):
11697 Change bufsize argument back to int, undoing my 2011-03-30 change.
11698 We prefer signed types, and int is wide enough here.
11699 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
11700 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
11701 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
11702 length, not size_t. Use ptrdiff_t for index, not int.
11703 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
11704 possibility of integer overflow.
11706 Overflow, signedness and related fixes for images.

11725 when the callers expect that.
11726 (image_ascent): Redo ascent calculation to avoid int overflow.
11727 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
11728 (lookup_image): Remove unnecessary tests.
11729 (xbm_image_p): Locals are now of int, not EMACS_INT,
11730 since parse_image_check makes sure they fit into int.
11731 (png_load, gif_load, svg_load_image):
11732 Prefer int to unsigned where either will do.
11733 (tiff_handler): New function, combining the cores of the
11734 old tiff_error_handler and tiff_warning_handler.
11735 This function is rewritten to use vsnprintf and thereby avoid
11736 stack buffer overflows. It uses only the features of vsnprintf
11737 that are common to both POSIX and native Microsoft.
11738 (tiff_error_handler, tiff_warning_handler): Use it.
11739 (tiff_load, gif_load, imagemagick_load_image):
11740 Don't assume :index value fits in 'int'.
11741 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
11742 (imagemagick_load_image): Check that crop parameters fit into
11743 the integer types that MagickCropImage accepts. Don't assume
11744 Vimagemagick_render_type has a nonnegative value. Don't assume
11745 size_t fits in 'long'.
11746 (gs_load): Use printmax_t to print the widest integers possible.
11747 Check for integer overflow when computing image height and width.

11756 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
11757 the display spec is of the form `(space ...)'.
11758 (handle_display_spec): Return the value returned by
11759 handle_single_display_spec, not just 1 or zero.
11760 (handle_single_display_spec): If the display spec is of the form
11761 `(space ...)', and specifies display in the text area, return 2
11763 (try_cursor_movement): Check for the need to scroll more
11764 accurately, and prefer exact match for point under bidi.
11765 Don't advance `row' beyond the last row of the window.
11767 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
11768 into disp_prop; all users changed.
11770 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
11771 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
11772 for the text covered by the display property.

11782 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
11783 buffers, return left-to-right.
11784 (set_cursor_from_row): Consider candidate row a win if its glyph
11785 represents a newline and point is on that newline. Fixes cursor
11786 positioning on the newline at EOL of R2L text within L2R
11787 paragraph, and vice versa.
11788 (try_cursor_movement): Check continued rows, in addition to
11789 continuation rows. Fixes unwarranted scroll when point enters a
11790 continued line of R2L text within an L2R paragraph, or vice versa.
11791 (cursor_row_p): Consider the case of point being equal to
11792 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
11793 from the end of a short line to the beginning of a continued line
11794 of R2L text within L2R paragraph.
11795 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
11796 composed characters.

11811 2011-08-22 Kenichi Handa <handa@m17n.org>
11813 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
11814 extra slot even if the purpose is char-code-property-table.
11816 2011-08-23 Eli Zaretskii <eliz@gnu.org>
11818 * xdisp.c (redisplay_window): When computing centering_position,
11819 account for the height of the header line. (Bug#8874)
11821 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
11822 instead of CHAR_TO_BYTE. Fixes a crash when a completion
11823 candidate is selected by the mouse, and that candidate has a
11824 composed character under the mouse.
11826 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
11827 coordinates reported by pos-visible-in-window-p for a composed
11828 character in column zero.
11830 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
11832 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
11834 2011-08-22 Eli Zaretskii <eliz@gnu.org>
11836 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
11837 consider it a hit if to_charpos is anywhere in the range of the
11838 composed buffer positions.
11840 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
11842 * image.c (gif_load): Don't assume that each subimage has the same
11843 dimensions as the base image. Handle disposal method that is
11844 "undefined" by the gif spec (Bug#9335).
11846 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
11848 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

11851 2011-08-19 Eli Zaretskii <eliz@gnu.org>
11853 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
11854 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
11855 from an Org mode buffer to a Speedbar frame.
11857 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
11858 a composition, take its buffer position from IT->cmp_it.charpos.
11859 Fixes cursor positioning at the beginning of a line that begins
11860 with a composed character.
11862 2011-08-18 Eli Zaretskii <eliz@gnu.org>
11864 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
11865 character bidirectional type, use STRONG_L instead. Fixes crashes
11866 in a buffer produced by `describe-categories'.
11868 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
11869 members before the level stack, so they would be saved and
11870 restored when copying iterator state. Fixes incorrect reordering
11871 around TABs covered by display properties.
11873 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
11875 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

11883 2011-08-17 Eli Zaretskii <eliz@gnu.org>
11885 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
11886 has no `load' handler, try opening the file locally. (Bug#9311)
11888 2011-08-16 Ken Brown <kbrown@cornell.edu>
11890 * gmalloc.c: Expand comment.

11943 2011-08-14 Eli Zaretskii <eliz@gnu.org>
11945 * xdisp.c (move_it_in_display_line_to): Don't invoke
11946 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
11947 ppos_it. Fixes vertical cursor motion when line beginning is
11948 covered by an image. (Bug#9296)
11950 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
11952 * nsterm.h (ns_run_ascript): Declare.

11956 (ns_run_ascript): New function.
11957 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
11958 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
11959 the event loop. Get status from as_status (Bug#7276).
11961 * nsterm.m (sendEvent): If event is NSApplicationDefined and
11962 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
11963 the event loop (Bug#7276).
11965 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

11988 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
11989 (Fnetwork_interface_list): Allocate in increments of bytes instead
11990 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
11991 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
11993 (struct ifflag_def): notrailers is smart on OSX.
11994 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
11995 Get hardware address with getifaddrs if available.
11997 2011-08-12 Eli Zaretskii <eliz@gnu.org>
11999 * xdisp.c (iterate_out_of_display_property): xassert that
12000 IT->position is set to within IT->object's boundaries. Break from
12001 the loop as soon as EOB is reached; avoids infloops in redisplay
12002 when IT->position is set up wrongly due to some bug.
12003 Set IT->current to match the bidi iterator unconditionally.
12004 (push_display_prop): Allow GET_FROM_STRING as IT->method on
12005 entry. Force push_it to save on the stack the current
12006 buffer/string position, to be restored by pop_it. Fix flags in
12007 the iterator structure wrt the object coming from a display
12008 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
12009 properties. (Bug#9284)
12011 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
12013 * fontset.c (fontset_get_font_group): Add proper type checks.

12026 no-display-properties-and-no-overlays under bidi display.
12027 Set disp_pos in the bidi iterator to avoid searches for display
12028 properties and overlays.
12030 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
12032 * editfns.c (Fset_time_zone_rule): Document relationship with the

12038 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
12040 * composite.c (autocmp_chars): Don't reset point. That is done by
12041 restore_point_unwind (Bug#5984).
12043 2011-08-07 Juri Linkov <juri@jurta.org>
12045 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
12046 to show the arg `TIME' instead of `TIMEVAL'.
12048 2011-08-06 Eli Zaretskii <eliz@gnu.org>
12050 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
12051 display property strides EOL and includes a newline, as in
12052 longlines-mode. (Bug#9254)
12053 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
12054 word-wrap under bidirectional display. (Bug#9224)
12056 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
12057 is non-zero, even if the data buffer is NULL. Fixes a crash in
12058 vertical-motion with longlines-mode. (Bug#9254)
12060 2011-08-05 Eli Zaretskii <eliz@gnu.org>
12062 * bidi.c <bidi_cache_total_alloc>: Now static.
12063 (bidi_initialize): Initialize bidi_cache_total_alloc.
12065 * xdisp.c (display_line): Release buffer allocated for shelved bidi
12068 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
12069 amount allocated this far in `bidi_cache_total_alloc'.
12070 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
12071 non-zero, only free the data buffer without restoring the cache
12072 contents. All callers changed.
12074 * dispextern.h (bidi_unshelve_cache): Update prototype.
12076 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
12077 (move_it_in_display_line, move_it_to)
12078 (move_it_vertically_backward, move_it_by_lines): Replace the call
12079 to xfree to an equivalent call to bidi_unshelve_cache.
12080 (move_it_in_display_line_to): Fix logic of returning
12081 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
12083 2011-08-05 Eli Zaretskii <eliz@gnu.org>
12085 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
12086 came from a string character with a `cursor' property. (Bug#9229)
12088 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
12090 * Makefile.in (LIB_PTHREAD): New variable.
12091 (LIBES): Add LIB_PTHREAD (Bug#9216).
12093 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:

12098 * regex.c (re_iswctype): Remove some redundant boolean conversions.
12100 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
12102 * xterm.c (x_find_topmost_parent): New function.
12103 (x_set_frame_alpha): Find topmost parent window with
12104 x_find_topmost_parent and set the property there also (bug#9181).
12105 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
12107 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
12109 * callproc.c (Fcall_process): Avoid vfork clobbering
12110 the local vars buffer, coding_systems, current_dir.
12112 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
12114 * keymap.c (Fmake_composed_keymap): Move to subr.el.
12116 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
12118 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
12119 so that it is not optimized away.
12121 * xdisp.c (compute_display_string_pos): Remove unused local.
12123 2011-08-02 Eli Zaretskii <eliz@gnu.org>
12125 Fix slow cursor motion and scrolling in large buffers with
12126 selective display, like Org Mode buffers. (Bug#9218)
12128 * dispextern.h (struct bidi_it): New member disp_prop_p.
12130 * xdisp.c: Remove one-slot cache of display string positions.
12131 (compute_display_string_pos): Accept an additional argument
12132 DISP_PROP_P; callers changed. Scan at most 5K characters forward
12133 for a display string or property. If found, set DISP_PROP_P
12136 * bidi.c (bidi_fetch_char): Accept an additional argument
12137 DISP_PROP_P, and pass it to compute_display_string_pos.
12138 Only handle text covered by a display string if DISP_PROP_P is returned
12139 non-zero. All callers of bidi_fetch_char changed.
12141 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
12143 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
12145 2010-12-03 Don March <don@ohspite.net>
12147 * keymap.c (Fdefine_key): Fix non-prefix key error message when
12148 last character M-[char] is translated to ESC [char] (bug#7541).
12150 2011-08-02 Kenichi Handa <handa@m17n.org>
12152 * lisp.h (uniprop_table): Extern it.
12154 * chartab.c (uniprop_table): Make it non-static.
12156 2011-08-01 Eli Zaretskii <eliz@gnu.org>
12158 * xdisp.c (forward_to_next_line_start): Accept additional argument
12159 BIDI_IT_PREV, and store into it the state of the bidi iterator had
12161 (reseat_at_next_visible_line_start): Use the bidi iterator state
12162 returned by forward_to_next_line_start to restore the state of
12163 it->bidi_it after backing up to previous newline. (Bug#9212)
12165 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
12167 * regex.c (re_comp): Protoize.
12168 (re_exec): Fix return type.
12169 (regexec): Fix type of `ret'. (Bug#9203)
12171 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12173 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
12174 This is needed if max-image-size is a floating-point number.
12176 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
12178 * print.c (print_object): Print empty symbol as ##.
12180 * lread.c (read1): Read ## as empty symbol.
12182 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
12184 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
12185 setting frame foreground color (Bug#9175).
12186 (x_set_background_color): Likewise.
12188 * nsmenu.m (-setText): Size tooltip dimensions precisely to
12189 contents (Bug#9176).
12190 (EmacsTooltip -init): Remove bezels and add shadows to
12193 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
12194 or scroll bar (Bug#8470).
12196 * nsfont.m (nsfont_open): Remove assignment to voffset and
12197 unnecessary vars hshink, expand, hd, full_height, min_height.
12198 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
12200 * nsterm.h (nsfont_info): Remove voffset field.
12202 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
12204 Implement strike-through and overline on NextStep (Bug#8863).
12206 * nsfont.m (nsfont_open): Use underline position provided by font,
12207 instead of hard-coded value of 2.
12208 (nsfont_draw): Call ns_draw_text_decoration instead.
12210 * nsterm.h: Add declaration for ns_draw_text_decoration.
12212 * nsterm.m (ns_draw_text_decoration): New function for drawing
12213 underline, overline, and strike-through.
12214 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
12215 ns_draw_text_decoration. Change treatment of cursor drawing to
12216 accommodate underlining, etc.
12218 2011-07-28 Eli Zaretskii <eliz@gnu.org>
12220 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
12223 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12225 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
12226 Without this fix, if a signal arrives just after memory fills up,
12227 'malloc' might be invoked reentrantly.
12229 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
12230 In other words, assume that every image size is allowed, on non-X
12231 hosts. This assumption is probably wrong, but it lets Emacs compile.
12233 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
12235 * regex.c (re_iswctype): Convert return values to boolean.
12237 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
12239 * xdisp.c (compute_display_string_pos): Don't use cached display
12240 string position if the buffer had its restriction changed.
12243 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12245 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12247 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12249 Integer signedness and overflow and related fixes. (Bug#9079)
12251 * bidi.c: Integer size and overflow fixes.
12252 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
12253 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
12254 (bidi_cache_find_level_change, bidi_cache_ensure_space)
12255 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
12256 (bidi_find_other_level_edge):
12257 Use ptrdiff_t instead of EMACS_INT where either will do.
12258 This works better on 32-bit hosts configured --with-wide-int.
12259 (bidi_cache_ensure_space): Check for size-calculation overflow.
12260 Use % rather than repeated addition, for better worst-case speed.
12261 Don't set bidi_cache_size until after xrealloc returns, because it
12263 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
12264 (bidi_cache_ensure_space): Also check that the bidi cache size
12265 does not exceed that of the largest Lisp string or buffer. See Eli
12266 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
12268 * alloc.c (__malloc_size_t): Remove.
12269 All uses replaced by size_t. See Andreas Schwab's note
12270 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
12272 * image.c: Improve checking for integer overflow.
12273 (check_image_size): Assume that f is nonnull, since
12274 it is always nonnull in practice. This is one less thing to
12275 worry about when checking for integer overflow later.
12276 (x_check_image_size): New function, which checks for integer
12277 overflow issues inside X.
12278 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
12279 This removes the need for a memory_full check.
12280 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
12281 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
12282 (xbm_read_bitmap_data): Change locals back to 'int', since
12283 their values must fit in 'int'.
12284 (xpm_load_image, png_load, tiff_load):
12285 Invoke x_create_x_image_and_pixmap earlier,
12286 to avoid much needless work if the image is too large.
12287 (tiff_load): Treat overly large images as if
12288 x_create_x_image_and_pixmap failed, not as malloc failures.
12289 (gs_load): Use x_check_image_size.
12291 * gtkutil.c: Omit integer casts.
12292 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
12293 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
12295 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
12297 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
12298 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
12299 would wrongly return t on a 64-bit host.
12301 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
12302 The plain *_OVERFLOW macros run afoul of GCC bug 49705
12303 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
12304 and therefore cause GCC to emit a bogus diagnostic in some cases.
12306 * image.c: Integer signedness and overflow and related fixes.
12307 This is not an exhaustive set of fixes, but it's time to
12308 record what I've got.
12309 (lookup_pixel_color, check_image_size): Remove redundant decls.
12310 (check_image_size): Don't assume that arbitrary EMACS_INT values
12311 fit in 'int', or that arbitrary 'double' values fit in 'int'.
12312 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
12313 (tiff_load, imagemagick_load_image):
12314 Check for overflow in size calculations.
12315 (x_create_x_image_and_pixmap): Remove unnecessary test for
12316 xmalloc returning NULL; that can't happen.
12317 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
12318 (xpm_color_bucket): Use better integer hashing function.
12319 (xpm_cache_color): Don't possibly over-allocate memory.
12320 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
12321 (gif_memory_source):
12322 Use ptrdiff_t, not int or size_t, to record sizes.
12323 (png_load): Don't assume values greater than 2**31 fit in 'int'.
12324 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
12325 either works, as we prefer signed integers.
12326 (tiff_read_from_memory, tiff_write_from_memory):
12327 Return tsize_t, not size_t, since that's what the TIFF API wants.
12328 (tiff_read_from_memory): Don't fail simply because the read would
12329 go past EOF; instead, return a short read.
12330 (tiff_load): Omit no-longer-needed casts.
12331 (Fimagemagick_types): Don't assume size fits into 'int'.
12333 Improve hashing quality when configured --with-wide-int.
12334 * fns.c (hash_string): New function, taken from sxhash_string.
12335 Do not discard information about ASCII character case; this
12336 discarding is no longer needed.
12337 (sxhash-string): Use it. Change sig to match it. Caller changed.
12338 * lisp.h: Declare it.
12339 * lread.c (hash_string): Remove, since we now use fns.c's version.
12340 The fns.c version returns a wider integer if --with-wide-int is
12341 specified, so this should help the quality of the hashing a bit.
12343 * emacs.c: Integer overflow minor fix.
12344 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
12345 Define only if GNU_LINUX.
12346 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
12348 * dispnew.c: Integer signedness and overflow fixes.
12349 Remove unnecessary forward decls, that were a maintenance hassle.
12350 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
12352 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
12353 (scrolling_window): Use ptrdiff_t, not int, for byte count.
12354 (prepare_desired_row, line_draw_cost):
12355 Use int, not unsigned, where either works.
12356 (save_current_matrix, restore_current_matrix):
12357 Use ptrdiff_t, not size_t, where either works.
12358 (init_display): Check for overflow more accurately, and without
12359 relying on undefined behavior.
12361 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
12362 Remove, replacing with the new symbols in lisp.h. All uses changed.
12363 * fileio.c (make_temp_name):
12364 * filelock.c (lock_file_1, lock_file):
12365 * xdisp.c (message_dolog):
12366 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
12367 Use pMd etc. instead.
12368 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
12369 replacing the pWIDE etc. symbols removed from editfns.c.
12371 * keyboard.h (num_input_events): Now uintmax_t.
12372 This is (very slightly) less likely to mess up due to wraparound.
12375 * buffer.c: Integer signedness fixes.
12376 (alloc_buffer_text, enlarge_buffer_text):
12377 Use ptrdiff_t rather than size_t when either will do, as we prefer
12380 * alloc.c: Integer signedness and overflow fixes.
12381 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
12382 (__malloc_size_t): Default to size_t, not to int.
12383 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
12384 (Fgarbage_collect, mark_object_loop_halt, mark_object):
12385 Prefer ptrdiff_t to size_t when either would do, as we prefer
12387 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
12388 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
12389 Now const. Initialize with values that are in range even if char
12391 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
12392 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
12393 These functions do the right thing with sizes > 2**32.
12394 (check_depth): Now ptrdiff_t, not int.
12395 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
12396 Adjust to new way of storing sizes. Check for size overflow bugs
12398 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
12399 slightly wrong anyway, as it missed one instance of
12400 XMALLOC_OVERRUN_CHECK_OVERHEAD.
12401 (refill_memory_reserve): Omit needless cast to size_t.
12402 (mark_object_loop_halt): Mark as externally visible.
12404 * xselect.c: Integer signedness and overflow fixes.
12405 (Fx_register_dnd_atom, x_handle_dnd_message):
12406 Use ptrdiff_t, not size_t, since we prefer signed.
12407 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
12408 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
12409 x_dnd_atoms_size and x_dnd_atoms_length.
12411 * doprnt.c: Prefer signed to unsigned when either works.
12413 * doprnt.c (doprnt):
12415 * xdisp.c (vmessage):
12416 Use ptrdiff_t, not size_t, when using or implementing doprnt,
12417 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
12418 prefer signed arithmetic to avoid comparison confusion.
12419 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
12420 but is a bit tricky.
12422 Assume freestanding C89 headers, string.h, stdlib.h.
12423 * data.c, doprnt.c, floatfns.c, print.c:
12424 Include float.h unconditionally.
12425 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
12426 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
12427 * regex.c: Likewise for stddef.h, string.h.
12428 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
12429 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
12430 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
12431 (STDC_HEADERS): Remove obsolete defines.
12432 * sysdep.c: Include limits.h unconditionally.
12434 Assume support for memcmp, memcpy, memmove, memset.
12435 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
12436 * regex.c (memcmp, memcpy):
12437 Remove; we assume C89 now.
12439 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
12440 (__malloc_safe_bcopy): Remove; no longer needed.
12442 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
12443 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
12444 well either way, and we prefer signed to unsigned.
12446 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
12448 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
12449 closes the connection while we're reading (bug#9182).
12451 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
12453 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
12454 are specified (Bug#9168).
12456 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
12458 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
12459 Found by GCC static checking and --with-wide-int on a 32-bit host.
12461 2011-07-25 Eli Zaretskii <eliz@gnu.org>
12463 * xdisp.c (compute_display_string_pos): Fix logic of caching
12464 previous display string position. Initialize cached_prev_pos to
12465 -1. Fixes slow-down at the beginning of a buffer.
12467 2011-07-24 Eli Zaretskii <eliz@gnu.org>
12469 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
12470 for attrs[LFACE_FONTSET_INDEX].
12472 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
12474 * xml.c (parse_region): Remove unused local
12475 that was recently introduced.
12477 2011-07-23 Eli Zaretskii <eliz@gnu.org>
12479 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
12480 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
12482 * xdisp.c (move_it_in_display_line_to): Record the best matching
12483 position for TO_CHARPOS while scanning the line, and restore it on
12484 exit if none of the characters scanned was an exact match.
12485 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
12486 when exact match is impossible due to invisible text, and the
12487 lines are truncated.
12489 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
12491 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
12494 2011-07-22 Eli Zaretskii <eliz@gnu.org>
12496 Fix a significant slow-down of cursor motion with C-n, C-p,
12497 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
12498 auto-repeat under bidi redisplay in fontified buffers.
12499 * xdisp.c (compute_stop_pos_backwards): New function.
12500 (next_element_from_buffer): Call compute_stop_pos_backwards to
12501 find a suitable prev_stop when we find ourselves before
12503 (reseat): Don't look for prev_stop, as that could mean a very long
12505 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
12506 <cached_disp_overlay_modiff>: Cache for last found display string
12508 (compute_display_string_pos): Return the cached position if asked
12509 about the same buffer in the same area of character positions, and
12510 the buffer wasn't changed since the time the display string
12511 position was cached.
12513 2011-07-22 Eli Zaretskii <eliz@gnu.org>
12515 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
12516 is an integer, which is important for empty lines. (Bug#9149)
12518 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
12520 * frame.c (Fmodify_frame_parameters): In tty case, update the
12521 default face if necessary (Bug#4238).
12523 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
12525 * editfns.c (Fstring_to_char): No need to explain what a character
12526 is in the docstring (Bug#6576).
12528 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
12530 * xml.c (parse_region): Make sure we always return a tree.
12532 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
12534 * xml.c (parse_region): If a document contains only comments,
12537 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
12539 * xml.c (make_dom): Return comments, too.

12546 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
12547 rather than fgets, and retry after EINTR. Otherwise, 'emacs
12548 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
12550 * s/openbsd.h (BROKEN_SIGIO): Define.
12551 * unexelf.c (unexec) [__OpenBSD__]:
12552 Don't update the .mdebug section of the Alpha COFF symbol table.
12554 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12556 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
12559 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
12561 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
12562 This fixes some race conditions on the permissions of any newly
12565 * alloc.c (valid_pointer_p): Use pipe, not open.
12566 This fixes some permissions issues when debugging.
12568 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
12569 If fchown fails to set both uid and gid, try to set just gid,
12570 as that is sometimes allowed. Adjust the file's mode to eliminate
12571 setuid or setgid bits that are inappropriate if fchown fails.
12573 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
12575 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
12576 to compare Lisp_Objects.

12581 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
12583 * lread.c (read_integer): Unread even EOF character.
12584 (read1): Likewise. Properly record start position of symbol.

12587 symbol character follows.
12589 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
12591 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
12592 This works around a problem with the previous change to Fcopy_file.
12593 Recent glibc declares fchown with __attribute__((warn_unused_result)),
12594 and without this change, GCC might complain about discarding
12595 fchown's return value.
12597 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
12599 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
12601 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
12603 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
12605 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
12607 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
12608 it's used from the C level.
12610 * process.c: Use the same condition for POLL_FOR_INPUT in both
12611 keyboard.c and process.c (bug#1858).
12613 2011-07-09 Lawrence Mitchell <wence@gmx.li>
12615 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
12616 (Fgnutls_boot): Use it.
12618 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
12620 * doc.c (Fsubstitute_command_keys): Revert last change.
12622 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
12624 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
12625 quotes the next character, and doesn't affect other longer
12626 sequences (bug#8935).
12628 * lread.c (syms_of_lread): Clarify that is isn't only
12629 `eval-buffer' and `eval-defun' that's affected by
12630 `lexical-binding' (bug#8460).
12632 2011-07-15 Eli Zaretskii <eliz@gnu.org>
12634 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
12635 bidi redisplay when a line includes both an image and is truncated.
12637 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
12639 Fix minor problems found by static checking.
12640 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
12641 (elsz): Now a signed constant, not a size_t var. We prefer signed
12642 types to unsigned, to avoid integer comparison confusion. Without
12643 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
12644 "cannot optimize loop, the loop counter may overflow", a symptom
12646 * indent.c (Fvertical_motion): Mark locals as initialized.
12647 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
12649 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

12675 (display_string): If we need to ignore text properties of
12676 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
12677 original value of -1 will not work with bidi.)
12678 (compute_display_string_pos): First arg is now struct
12679 `text_pos *'; all callers changed. Support display properties on

12683 (init_iterator, reseat_1, reseat_to_string): Initialize the
12684 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
12685 when iterating on a string not from display properties).
12686 (compute_display_string_pos, compute_display_string_end):
12687 Fix calculation of the object to scan. Fixes an error when using
12689 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
12690 base_level_stop; instead, set base_level_stop to BEGV.
12691 Fixes crashes in vertical-motion.
12692 (next_element_from_buffer): Improve commentary for when
12693 the iterator is before prev_stop.
12694 (init_iterator): Initialize bidi_p from the default value of
12695 bidi-display-reordering, not from buffer-local value. Use the
12696 buffer-local value only if initializing for buffer iteration.

12717 parts of next_element_from_buffer, next_element_from_string, and
12718 next_element_from_c_string.
12719 (tool_bar_lines_needed, redisplay_tool_bar)
12720 (display_menu_bar): Force left-to-right direction. Add a FIXME

12735 pushed the iterator stack, restore the internal state of the bidi
12736 iterator by calling bidi_pop_it same number of times.
12737 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
12738 and we are bidi-iterating, don't decrement the iterator position;
12739 instead, set the first_elt flag in the bidi iterator, to produce
12741 (reseat_1): Remove redundant setting of string_from_display_prop_p.
12742 (push_display_prop): xassert that we are iterating a buffer.

12746 (push_display_prop): Set up the `unibyte' member of bidi_it.string
12747 correctly. Don't assume unibyte strings are not bidi-reordered.

12756 property. Fix a typo in popping stretch info. Add an assertion
12757 for verifying that the iterator position is in sync with the bidi
12759 (handle_single_display_spec, get_overlay_strings_1)

12849 (struct iterator_stack_entry): New members bidi_p,
12850 paragraph_embedding, and from_disp_prop_p.

13171 (clone_per_buffer_values): Don't assume that
13172 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
13173 This isn't true in general, and it's particularly not true
13174 if Emacs is configured with --with-wide-int.
13175 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
13176 New macros, used in the buffer.c change.

13212 Random fixes. E.g., (random) never returned negative values.
13213 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
13214 subseconds part to the entropy, as that's a bit more random.
13215 Prefer signed to unsigned, since the signedness doesn't matter and
13216 in general we prefer signed. When given a limit, use a
13217 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
13218 latter isn't right if USE_2_TAGS_FOR_INTS.
13219 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
13220 not 0..VALMASK. Don't discard "excess" bits that random () returns.

13232 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
13233 This is more efficient than Ffile_directory_p and avoids a minor race.
13235 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
13237 * buffer.c (Foverlay_put): Say what the return value is
13240 * fileio.c (barf_or_query_if_file_exists): Check first if the file
13241 is a directory before asking whether to use the file name
13243 (barf_or_query_if_file_exists): Make the "File is a directory"
13244 error be more correct.
13246 * fns.c (Frequire): Remove the mention of the .gz files, since
13247 that's installation-specific, but keep the mention of
13248 `get-load-suffixes'.

13252 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

13260 Qgnutls_bootprop_verify_error (which is no longer used).
13262 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
13263 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
13264 Also (re)move comments that are misplaced or no longer relevant.

13289 leave any prefix arg for the up event (Bug#1586).
13291 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
13293 * lread.c (syms_of_lread): Mention single symbols defined by
13294 `defvar' or `defconst' (bug#7154).
13296 * fns.c (Frequire): Mention .el.gz files (bug#7314).
13297 (Frequire): Mention get-load-suffixes.

13327 (syms_of_keymap): Defsubr make-composed-keymap.
13328 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

13365 * eval.c (struct backtrace): Simplify and port the data structure.
13366 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
13367 signed bit field, as this assumption is not portable and it makes
13368 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
13369 "char debug_on_exit : 1" as this is not portable either; instead,
13370 use the portable "unsigned int debug_on_exit : 1". Remove unused
13371 member evalargs. Remove obsolete comments about cc bombing out.
13373 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

13461 * process.c (wait_reading_process_output): Bypass select if
13462 waiting for a cell while ignoring keyboard input, and input is
13463 pending. Suggested by Jan Djärv (Bug#8869).

13467 Use gnulib's dup2 module instead of rolling our own.
13468 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

13539 * print.c (printchar, strout): Check for string overflow.
13540 (PRINTPREPARE, printchar, strout):
13541 Don't set size unless allocation succeeds.
13543 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
13544 for sizes. Check for string overflow more accurately.
13545 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
13547 * macros.c: Integer and buffer overflow fixes.
13548 * keyboard.h (struct keyboard.kbd_macro_bufsize):
13549 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

13553 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
13555 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
13557 * lread.c: Integer overflow fixes.
13558 (read_integer): Radix is now EMACS_INT, not int,
13559 to improve quality of diagnostics for out-of-range radices.
13560 Calculate buffer size correctly for out-of-range radices.
13561 (read1): Check for integer overflow in radices, and in
13562 read-circle numbers.
13563 (read_escape): Avoid int overflow.
13564 (Fload, openp, read_buffer_size, read1)
13565 (substitute_object_recurse, read_vector, read_list, map_obarray):

13581 2011-06-22 Leo Liu <sdl.web@gmail.com>
13583 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
13584 Move to minibuffer.el.
13586 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
13588 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
13589 The following patches are for when GLYPH_DEBUG && !XASSERT.
13590 * dispextern.h (trace_redisplay_p, dump_glyph_string):
13591 * dispnew.c (flush_stdout):
13592 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
13593 Mark as externally visible.
13594 * dispnew.c (check_window_matrix_pointers): Now static.
13595 * dispnew.c (window_to_frame_vpos):
13596 * xfns.c (unwind_create_frame):
13597 * xterm.c (x_check_font): Remove unused local.
13598 * scroll.c (CHECK_BOUNDS):
13599 * xfaces.c (cache_fache): Rename local to avoid shadowing.
13600 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
13601 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
13602 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
13603 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
13605 (debug_method_add): Use va_list and vsprintf rather than relying
13606 on undefined behavior with wrong number of arguments.
13607 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
13608 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
13609 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
13610 since we're not interested in debugging glyphs with old libraries.
13611 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
13612 GCC 4.6.0's static checking.
13614 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

13632 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
13633 (.bitmaps_last, struct x_output.icon_bitmap):
13634 Use ptrdiff_t, not int, for bitmap indexes.
13635 (x_allocate_bitmap_record): Check for size overflow.
13636 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
13638 Use ptrdiff_t, not int, for overlay counts.
13639 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
13640 * editfns.c (overlays_around, get_pos_property):

13642 * xdisp.c (next_overlay_change, note_mouse_highlight):
13643 * xfaces.c (face_at_buffer_position):
13644 * buffer.c (OVERLAY_COUNT_MAX): New macro.
13645 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
13646 (Fnext_overlay_change, Fprevious_overlay_change)
13647 (mouse_face_overlay_overlaps, Foverlays_in):
13648 Use ptrdiff_t, not int, for sizes.
13649 (overlays_at, overlays_in): Check for size-calculation overflow.
13651 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
13653 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
13654 (x_session_initialize): Do not assume string length fits in int.
13656 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
13657 This is unlikely, but can occur if DPI is outlandish.
13659 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
13660 * xselect.c (Fx_get_atom_name): Avoid need for strlen.

13663 * xrdb.c (magic_file_p, search_magic_path):
13664 Omit last arg SUFFIX; it was always 0. All callers changed.
13665 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
13667 * xfont.c (xfont_match): Avoid need for strlen.
13669 * xfns.c: Don't assume strlen fits in int.

13672 * xdisp.c (message_log_check_duplicate): Return intmax_t,
13673 not unsigned long, as we prefer signed integers. All callers changed.
13674 Detect integer overflow in repeat count.
13675 (message_dolog): Don't assume print length fits in 39 bytes.
13676 (display_mode_element): Don't assume strlen fits in int.
13678 * termcap.c: Don't assume sizes fit in int and never overflow.
13679 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
13680 (gobble_line): Check for size-calculation overflow.
13682 * minibuf.c (Fread_buffer):
13683 * lread.c (intern, intern_c_string):

13697 * filelock.c: Fix some buffer overrun and integer overflow issues.
13698 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
13699 Reformulate so as not to need the command string.
13700 Invoke gzip -cd rather than gunzip, as it's more portable.
13701 (lock_info_type, lock_file_1, lock_file):
13702 Don't assume pid_t and time_t fit in unsigned long.
13703 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
13704 (current_lock_owner): Prefer signed type for sizes.
13705 Use memcpy, not strncpy, where memcpy is what is really wanted.
13706 Don't assume (via atoi) that time_t and pid_t fit in int.
13707 Check for time_t and/or pid_t out of range, e.g., via a network share.
13708 Don't alloca where an auto var works fine.
13710 * fileio.c: Fix some integer overflow issues.
13711 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
13712 Don't assume string length fits in int.
13713 (directory_file_name): Don't assume string length fits in long.
13714 (make_temp_name): Don't assume pid fits in int, or that its print
13715 length is less than 20.

13735 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
13737 * lread.c (invalid_syntax): Omit length argument.
13738 All uses changed. This doesn't fix a bug, but it simplifies the
13739 code away from its former Hollerith-constant appearance, and it's
13740 one less 'int' to worry about when looking at integer-overflow issues.
13741 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
13743 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
13744 This didn't break anything, but it didn't help either.
13745 It's confusing to put a bogus integer in a place where the actual
13746 value does not matter.
13747 (LIST_END_P): Remove unused macro and its bogus comment.
13748 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
13750 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
13751 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
13753 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
13754 We prefer signed types, and the value cannot exceed the EMACS_INT
13755 range anyway (because otherwise the length would not be representable).
13756 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
13757 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
13758 This avoids a GCC warning when WIDE_EMACS_INT.
13760 * indent.c (sane_tab_width): New function.
13761 (current_column, scan_for_column, Findent_to, position_indentation)
13762 (compute_motion): Use it. This is just for clarity.
13763 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.

13769 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
13771 * editfns.c, insdel.c:
13772 Omit unnecessary forward decls, to simplify future changes.
13774 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
13776 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
13778 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
13779 Use much-faster test for byte-length change.
13780 Don't assume string byte-length fits in 'int'.
13781 Check that character arg fits in 'int'.
13782 (mapcar1): Declare byte as byte, for clarity.
13784 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
13786 * fns.c (concat): Catch string overflow earlier.
13787 Do not rely on integer wraparound.
13789 * dispextern.h (struct it.overlay_strings_charpos)
13790 (struct it.selective): Now EMACS_INT, not int.
13791 * xdisp.c (forward_to_next_line_start)
13792 (back_to_previous_visible_line_start)
13793 (reseat_at_next_visible_line_start, next_element_from_buffer):
13794 Don't arbitrarily truncate the value of 'selective' to int.
13796 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
13798 * composite.c: Don't truncate sizes to 'int'.
13799 (composition_gstring_p, composition_reseat_it)
13800 (composition_adjust_point): Use EMACS_INT, not int.
13801 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
13802 not EMACS_UINT, for indexes.
13804 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
13806 * buffer.c: Include <verify.h>.
13807 (struct sortvec.priority, struct sortstr.priority):
13808 Now EMACS_INT, not int.
13809 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
13810 (struct sortstr.size, record_overlay_string)
13811 (struct sortstrlist.size, struct sortlist.used):
13812 Don't truncate size to int.
13813 (record_overlay_string): Check for size-calculation overflow.
13814 (init_buffer_once): Check at compile-time, not run-time.
13816 2011-06-22 Jim Meyering <meyering@redhat.com>
13818 Don't leak an XBM-image-sized buffer
13819 * image.c (xbm_load): Free the image buffer after using it.
13821 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
13824 * composite.c (find_automatic_composition): Omit needless 'return 0;'
13825 that Sun C diagnosed.
13826 * fns.c (secure_hash): Fix pointer signedness issue.
13827 * intervals.c (static_offset_intervals): New function.
13828 (offset_intervals): Use it.
13830 2011-06-21 Leo Liu <sdl.web@gmail.com>
13833 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
13836 * fns.c (secure_hash): Rename from crypto_hash_function and change
13837 the first arg to accept symbols.
13838 (Fsecure_hash): New primitive.
13839 (syms_of_fns): New symbols.
13841 2011-06-20 Deniz Dogan <deniz@dogan.se>
13843 * process.c (Fset_process_buffer): Clarify return value in

13858 check till after the cache is created in init_frame_faces.
13860 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
13862 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
13864 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
13866 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
13867 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
13868 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
13870 Improve buffer-overflow checking (Bug#8873).
13871 * fileio.c (Finsert_file_contents):
13872 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
13873 Remove the old (too-loose) buffer overflow checks.
13874 They weren't needed, since make_gap checks for buffer overflow.
13875 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
13876 The old code merely checked for Emacs fixnum overflow, and relied
13877 on undefined (wraparound) behavior. The new code avoids undefined
13878 behavior, and also checks for ptrdiff_t and/or size_t overflow.
13880 * editfns.c (Finsert_char): Don't dump core with very negative counts.
13881 Tune. Don't use wider integers than needed. Don't use alloca.
13882 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
13884 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
13886 * insdel.c, lisp.h (buffer_overflow): New function.
13887 (insert_from_buffer_1, replace_range, replace_range_2):
13888 * insdel.c (make_gap_larger):
13889 * editfns.c (Finsert_char):
13890 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
13892 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
13894 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
13896 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
13898 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
13899 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
13901 * fileio.c: Don't assume EMACS_INT fits in off_t.
13902 (emacs_lseek): New static function.
13903 (Finsert_file_contents, Fwrite_region): Use it.
13904 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
13906 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
13908 * fns.c: Don't overflow int when computing a list length.
13909 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
13910 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
13911 truncation on 64-bit hosts. Check for QUIT every
13912 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
13913 faster and is responsive enough.
13914 (Flength): Report an error instead of overflowing an integer.
13915 (Fsafe_length): Return a float if the value is not representable
13916 as a fixnum. This shouldn't happen except in contrived situations.
13917 (Fnthcdr, Fsort): Don't assume list length fits in int.
13918 (Fcopy_sequence): Don't assume vector length fits in int.
13920 * alloc.c: Check that resized vectors' lengths fit in fixnums.
13921 (header_size, word_size): New constants.
13922 (allocate_vectorlike): Don't check size overflow here.
13923 (allocate_vector): Check it here instead, since this is the only
13924 caller of allocate_vectorlike that could cause overflow.
13925 Check that the new vector's length is representable as a fixnum.
13927 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
13928 The previous code was bogus. For example, next_almost_prime (32)
13929 returned 39, which is undesirable as it is a multiple of 3; and
13930 next_almost_prime (24) returned 25, which is a multiple of 5 so
13931 why was the code bothering to check for multiples of 7?
13933 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
13935 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
13937 Variadic C functions now count arguments with ptrdiff_t.
13938 This partly undoes my 2011-03-30 change, which replaced int with size_t.
13939 Back then I didn't know that the Emacs coding style prefers signed int.
13940 Also, in the meantime I found a few more instances where arguments
13941 were being counted with int, which may truncate counts on 64-bit
13942 machines, or EMACS_INT, which may be unnecessarily wide.
13943 * lisp.h (struct Lisp_Subr.function.aMANY)
13944 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
13945 Arg counts are now ptrdiff_t, not size_t.
13946 All variadic functions and their callers changed accordingly.
13947 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
13948 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
13949 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
13950 * callint.c (Fcall_interactively): Check arg count for overflow,
13951 to avoid potential buffer overrun. Use signed char, not 'int',
13952 for 'varies' array, so that we needn't bother to check its size
13953 calculation for overflow.
13954 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
13955 * eval.c (apply_lambda):
13956 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
13957 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
13958 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
13960 * callint.c (Fcall_interactively): Don't use index var as event count.
13962 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
13963 * mem-limits.h (SIZE): Remove; no longer used.
13965 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
13967 Remove unnecessary casts.
13968 * xterm.c (x_term_init):
13969 * xfns.c (x_set_border_pixel):
13970 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
13971 These aren't needed now that we assume ANSI C.
13973 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
13974 It's more likely to cause problems (due to unsigned overflow)
13977 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
13979 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
13981 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
13983 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
13985 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
13987 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
13989 GLYPH_CODE_FACE returns EMACS_INT, not int.
13990 * dispextern.h (merge_faces):
13991 * xfaces.c (merge_faces):
13992 * xdisp.c (get_next_display_element, next_element_from_display_vector):
13993 Don't assume EMACS_INT fits in int.
13995 * character.h (CHAR_VALID_P): Remove unused parameter.
13996 * fontset.c, lisp.h, xdisp.c: All uses changed.
13998 * editfns.c (Ftranslate_region_internal): Omit redundant test.
14000 * fns.c (concat): Minor tuning based on overflow analysis.
14001 This doesn't fix any bugs. Use int to hold character, instead
14002 of constantly refetching from Emacs object. Use XFASTINT, not
14003 XINT, for value known to be a character. Don't bother comparing
14004 a single byte to 0400, as it's always less.
14006 * floatfns.c (Fexpt):
14007 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
14009 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
14012 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
14014 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
14015 Without this fix, on a 64-bit host (aset S 0 4294967386) would
14016 incorrectly succeed when S was a string, because 4294967386 was
14017 truncated before it was used.
14019 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
14020 Otherwise, an out-of-range integer could cause undefined behavior
14023 * composite.c: Use int, not EMACS_INT, for characters.
14024 (fill_gstring_body, composition_compute_stop_pos): Use int, not
14025 EMACS_INT, for values that are known to be in character range.
14026 This doesn't fix any bugs but is the usual style inside Emacs and
14027 may generate better code on 32-bit machines.
14029 Make sure a 64-bit char is never passed to ENCODE_CHAR.
14030 This is for reasons similar to the recent CHAR_STRING fix.
14031 * charset.c (Fencode_char): Check that character arg is actually
14032 a character. Pass an int to ENCODE_CHAR.
14033 * charset.h (ENCODE_CHAR): Verify that the character argument is no
14034 wider than 'int', as a compile-time check to prevent future regressions
14037 * character.c (char_string): Remove unnecessary casts.
14039 Make sure a 64-bit char is never passed to CHAR_STRING.
14040 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
14041 by silently ignoring the top 32 bits, allowing some values
14042 that were far too large to be valid characters.
14043 * character.h: Include <verify.h>.
14044 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
14045 arguments are no wider than unsigned, as a compile-time check
14046 to prevent future regressions in this area.
14048 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
14049 (Fsubst_char_in_region):
14051 * xdisp.c (decode_mode_spec_coding):
14052 Adjust to CHAR_STRING's new requirement.
14053 * editfns.c (Finsert_char, Fsubst_char_in_region):
14054 * fns.c (concat): Check that character args are actually
14055 characters. Without this test, these functions did the wrong
14056 thing with wildly out-of-range values on 64-bit hosts.
14058 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
14059 These casts should not be needed on 32-bit hosts, either.
14060 * keyboard.c (read_char):
14061 * lread.c (Fload): Remove casts to unsigned.
14063 * lisp.h (UNSIGNED_CMP): New macro.
14064 This fixes comparison bugs on 64-bit hosts.
14065 (ASCII_CHAR_P): Use it.
14066 * casefiddle.c (casify_object):
14067 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
14068 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
14069 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
14070 * dispextern.h (FACE_FROM_ID):
14071 * keyboard.c (read_char): Use UNSIGNED_CMP.
14073 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
14074 not to EMACS_INT, to avoid GCC warning.
14076 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
14078 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
14079 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
14080 isn't needed on 32-bit machines.
14082 * buffer.c (Fgenerate_new_buffer_name):
14083 Use EMACS_INT for count, not int.
14084 (advance_to_char_boundary): Return EMACS_INT, not int.
14086 * data.c (Qcompiled_function): Now static.
14088 * window.c (window_body_lines): Now static.
14090 * image.c (gif_load): Rename local to avoid shadowing.
14092 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
14093 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
14094 * alloc.c (make_save_value): Integer argument is now of type
14095 ptrdiff_t, not int.
14096 (mark_object): Use ptrdiff_t, not int.
14097 * lisp.h (pD): New macro.
14098 * print.c (print_object): Use it.
14100 * alloc.c: Use EMACS_INT, not int, to count objects.
14101 (total_conses, total_markers, total_symbols, total_vector_size)
14102 (total_free_conses, total_free_markers, total_free_symbols)
14103 (total_free_floats, total_floats, total_free_intervals)
14104 (total_intervals, total_strings, total_free_strings):
14105 Now EMACS_INT, not int. All uses changed.
14106 (Fgarbage_collect): Compute overall total using a double, so that
14107 integer overflow is less likely to be a problem. Check for overflow
14108 when converting back to an integer.
14109 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
14110 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
14111 These were 'int' variables that could overflow on 64-bit hosts;
14112 they were never used, so remove them instead of repairing them.
14113 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
14114 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
14115 Previously, this ceilinged at INT_MAX, but that doesn't work on
14117 (allocate_pseudovector): Don't use EMACS_INT when int would do.
14119 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
14120 (allocate_vectorlike): Check for ptrdiff_t overflow.
14121 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
14122 when a (possibly-narrower) signed value would do just as well.
14123 We prefer using signed arithmetic, to avoid comparison confusion.
14125 * alloc.c: Catch some string size overflows that we were missing.
14126 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
14127 for convenience in STRING_BYTES_MAX.
14128 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
14129 The definition here is exact; the one in lisp.h was approximate.
14130 (allocate_string_data): Check for string overflow. This catches
14131 some instances we weren't catching before. Also, it catches
14132 size_t overflow on (unusual) hosts where SIZE_MAX <= min
14133 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
14134 and ptrdiff_t and EMACS_INT are both 64 bits.
14136 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
14137 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
14138 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
14140 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
14142 * alloc.c (Fmake_string): Check for out-of-range init.
14144 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
14146 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
14148 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
14150 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
14151 xg_get_default_scrollbar_width.
14153 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
14154 (int_gtk_range_get_value): Move to the scroll bar part of the file.
14155 (style_changed_cb): Call update_theme_scrollbar_width and call
14156 x_set_scroll_bar_default_width and xg_frame_set_char_size for
14157 all frames (Bug#8505).
14158 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
14159 Call gtk_window_set_resizable if HAVE_GTK3.
14160 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
14161 and height if HAVE_GTK3 (Bug#8505).
14162 (scroll_bar_width_for_theme): New variable.
14163 (update_theme_scrollbar_width): New function.
14164 (xg_get_default_scrollbar_width): Move code to
14165 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
14166 (xg_initialize): Call update_theme_scrollbar_width.
14168 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
14170 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
14172 2011-06-12 Martin Rudalics <rudalics@gmx.at>
14174 * frame.c (make_frame): Call other_buffer_safely instead of
14177 * window.c (temp_output_buffer_show): Call display_buffer with
14178 second argument Vtemp_buffer_show_specifiers and reset latter
14179 immediately after the call.
14180 (Vtemp_buffer_show_specifiers): New variable.
14181 (auto_window_vscroll_p, next_screen_context_lines)
14182 (Vscroll_preserve_screen_position): Remove leading asterisks from
14185 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
14187 Fix minor problems found by GCC 4.6.0 static checking.
14188 * buffer.c (Qclone_number): Remove for now, as it's unused.
14189 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
14190 (record_buffer): Remove unused local.
14191 * frame.c (other_visible_frames, frame_buffer_list): Now static.
14192 (set_frame_buffer_list): Remove; unused.
14193 * frame.h (other_visible_frames): Remove decl.
14194 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
14195 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
14196 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
14198 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
14199 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
14200 Define only if HAVE_GPM.
14201 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
14202 (update_hints_inhibit): Remove; never set. All uses removed.
14203 * widgetprv.h (emacsFrameClassRec): Remove decl.
14204 * window.c (delete_deletable_window): Now returns void, since it
14205 wasn't returning anything.
14206 (compare_window_configurations): Remove unused locals.
14207 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
14208 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
14209 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
14210 the same widths as pointers. This follows up on the 2011-05-06 patch.
14211 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
14212 * xterm.h: Likewise.
14213 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
14215 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
14217 * makefile.w32-in: Update dependencies.
14218 (LISP_H): Add lib/intprops.h.
14220 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
14222 * image.c (gif_load): Add animation frame delay to the metadata.
14223 (syms_of_image): Use DEFSYM. New symbol `delay'.
14225 2011-06-11 Martin Rudalics <rudalics@gmx.at>
14227 * window.c (delete_deletable_window): Re-add.
14228 (Fset_window_configuration): Rewrite to handle dead buffers and
14229 consequently deletable windows.
14230 (window_tree, Fwindow_tree): Remove. Supply functionality in
14232 (compare_window_configurations): Simplify code.
14234 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
14236 * image.c (imagemagick_load_image): Fix type mismatch.
14237 (Fimagemagick_types): Likewise.
14239 * window.h (replace_buffer_in_windows): Declare.
14241 2011-06-11 Martin Rudalics <rudalics@gmx.at>
14243 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
14244 Qclone_number. Remove external declaration of Qdelete_window.
14245 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
14247 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
14248 Run Qbuffer_list_update_hook if allowed.
14249 (Fother_buffer): Rewrite doc-string. Major rewrite for new
14250 buffer list implementation.
14251 (other_buffer_safely): New function.
14252 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
14253 calls to replace_buffer_in_windows and
14254 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
14256 (record_buffer): Inhibit quitting and rewrite using quittable
14257 functions. Run Qbuffer_list_update_hook if allowed.
14258 (Frecord_buffer, Funrecord_buffer): New functions.
14259 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
14260 Move switch-to-buffer to window.el.
14261 (bury-buffer): Move to window.el.
14262 (Vbuffer_list_update_hook): New variable.
14264 * lisp.h (other_buffer_safely): Add prototype in buffer.c
14267 * window.h (resize_frame_windows): Move up in code.
14268 (Fwindow_frame): Remove EXFUN.
14269 (replace_buffer_in_all_windows): Remove prototype.
14270 (replace_buffer_in_windows_safely): Add prototype.
14272 * window.c: Declare Qdelete_window static again. Move down
14273 declaration of select_count.
14274 (Fnext_window, Fprevious_window): Rewrite doc-strings.
14275 (Fother_window): Move to window.el.
14276 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
14277 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
14278 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
14280 (replace_buffer_in_windows): Implement by calling
14281 Qreplace_buffer_in_windows.
14282 (replace_buffer_in_all_windows): Remove with some functionality
14283 moved into replace_buffer_in_windows_safely.
14284 (replace_buffer_in_windows_safely): New function.
14285 (select_window_norecord, select_frame_norecord): Move in front
14286 of run_window_configuration_change_hook. Remove now obsolete
14288 (Fset_window_buffer): Rewrite doc-string.
14289 Call Qrecord_window_buffer.
14290 (keys_of_window): Move binding for other-window to window.el.
14292 2011-06-11 Chong Yidong <cyd@stupidchicken.com>

14738 (single_display_spec_string_p): Support property values that are
14739 lists with the argument STRING its top-level element.
14740 (display_prop_string_p): Fix the condition for processing a
14741 property that is a list to be consistent with handle_display_spec.
14742 (handle_display_spec): New function, refactored from the
14743 last portion of handle_display_prop.
14744 (compute_display_string_pos): Accept additional argument
14745 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
14746 value of a `display' property is a "replacing spec".
14747 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
14748 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
14749 the display property, but just return a value indicating whether
14750 the display property will replace the characters it covers.
14751 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
14752 frame_window_p members of struct bidi_it.
14753 (compute_display_string_pos, compute_display_string_end):
14755 (push_it): Accept second argument POSITION, where pop_it should
14756 jump to continue iteration.
14757 (reseat_1): Initialize bidi_it.disp_pos.
14759 * keyboard.c (adjust_point_for_property): Adjust the call to
14760 display_prop_intangible_p to its new signature.

14770 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
14772 Malloc failure behavior now depends on size of allocation.
14773 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
14774 * lisp.h: Change signatures accordingly.
14775 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
14776 All callers changed. (Bug#8762)
14778 * gnutls.c: Use Emacs's memory allocators.
14779 Without this change, the gnutls library would invoke malloc etc.
14780 directly, which causes problems on non-SYNC_INPUT hosts, and which
14781 runs afoul of improving memory_full behavior. (Bug#8761)
14782 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
14783 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
14784 xfree instead of the default malloc, realloc, free.
14785 (Fgnutls_boot): No need to check for memory allocation failure,
14786 since xmalloc does that for us.
14788 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
14789 * category.c (hash_get_category_set):
14790 * ccl.c (ccl_driver):
14791 * charset.c (Fdefine_charset_internal):

14803 (Fsxhash, Fgethash, Fputhash, Fmaphash):
14804 * image.c (make_image, search_image_cache, lookup_image)
14805 (xpm_put_color_table_h):
14806 * lisp.h (struct Lisp_Hash_Table):
14807 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
14808 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
14809 for hashes and hash indexes, instead of 'unsigned' and 'int'.
14810 * alloc.c (allocate_vectorlike):
14811 Check for overflow in vector size calculations.
14812 * ccl.c (ccl_driver):
14813 Check for overflow when converting EMACS_INT to int.
14814 * fns.c, image.c: Remove unnecessary static decls that would otherwise
14815 need to be updated by these changes.
14816 * fns.c (make_hash_table, maybe_resize_hash_table):
14817 Check for integer overflow with large hash tables.
14818 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
14819 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
14820 (SXHASH_REDUCE): New macro.
14821 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
14822 Use it instead of discarding useful hash info with large hash values.
14823 (sxhash_float): New function.
14824 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
14825 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
14826 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
14827 Rewrite to use FIXNUM_BITS, as this simplifies things.
14828 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
14829 Adjust signatures to match updated version of code.
14830 (consing_since_gc): Now EMACS_INT, since a single hash table can
14831 use more than INT_MAX bytes.
14833 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
14835 Make it possible to build with GCC-4.6+ -O2 -flto.
14837 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
14839 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
14841 * minibuf.c (get_minibuffer, read_minibuf_unwind):
14842 Call minibuffer-inactive-mode.
14844 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
14846 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
14847 Update dependencies.
14849 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14851 * data.c (init_data): Remove code for UTS, this system is not
14854 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14856 Don't force ./temacs to start in terminal mode.
14858 * frame.c (make_initial_frame): Initialize faces in all cases, not
14859 only when CANNOT_DUMP is defined.
14860 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
14862 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14864 * dispnew.c (add_window_display_history): Use const for the string
14865 pointer. Remove declaration, not needed.
14867 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
14869 Use 'inline', not 'INLINE'.
14870 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
14871 * alloc.c, fontset.c (INLINE): Remove.
14872 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
14873 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
14874 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
14875 * gmalloc.c (register_heapinfo): Use inline unconditionally.
14876 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
14878 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14880 Make it possible to run ./temacs.
14882 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
14883 syms_of_callproc does the same thing. Remove test for
14884 "initialized", do it in the caller.
14885 * emacs.c (main): Avoid calling set_initial_environment when dumping.
14887 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
14889 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
14890 (read_minibuf): Use get_minibuffer.
14891 (syms_of_minibuf): Use DEFSYM.
14892 (Qmetadata): New var.
14893 * data.c (Qbuffer): Don't make it static.
14894 (syms_of_data): Use DEFSYM.
14896 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
14898 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
14899 (CCL_CODE_MIN): New macro.
14901 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
14903 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
14905 * eval.c (Qdebug): Now static.
14906 * lisp.h (Qdebug): Remove decl. This reverts a part of the
14907 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
14908 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
14910 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14912 * image.c: Various fixes to ImageMagick code comments.
14913 (Fimagemagick_types): Doc fix.
14915 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
14917 Minor fixes prompted by GCC 4.6.0 warnings.
14919 * xselect.c (converted_selections, conversion_fail_tag): Now static.
14921 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
14922 (x_clipboard_manager_save_all): Move extern decl to ...
14923 * xterm.h: ... here, so that it can be checked for consistency.
14925 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14927 * xselect.c (x_clipboard_manager_save_frame)
14928 (x_clipboard_manager_save_all): New functions.
14929 (Fx_clipboard_manager_save): Lisp function deleted.
14931 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
14932 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
14934 * xterm.h: Update prototype.
14936 2011-05-28 William Xu <william.xwl@gmail.com>
14938 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
14939 exiting (Bug#8239).
14941 2011-05-28 Jim Meyering <meyering@redhat.com>
14943 Avoid a sign-extension bug in crypto_hash_function.
14944 * fns.c (to_uchar): Define.
14945 (crypto_hash_function): Use it to convert some newly-signed
14946 variables to unsigned, to avoid sign-extension bugs. For example,
14947 without this change, (md5 "truc") would evaluate to
14948 45723a2aff78ff4fff7fff1114760e62 rather than the expected
14949 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
14950 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
14952 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14954 Integer overflow fixes.
14956 * dbusbind.c: Serial number integer overflow fixes.
14957 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
14958 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
14959 to hold a serial number that is too large for a fixnum.
14960 (Fdbus_method_return_internal, Fdbus_method_error_internal):
14961 Check for serial numbers out of range. Decode any serial number
14962 that was so large that it became a float. (Bug#8722)
14964 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
14965 (Fdbus_call_method, Fdbus_call_method_asynchronously):
14966 Use XFASTINT rather than XUINT when numbers are nonnegative.
14967 (xd_append_arg, Fdbus_method_return_internal):
14968 (Fdbus_method_error_internal): Likewise. Also, for unsigned
14969 arguments, check that Lisp number is nonnegative, rather than
14970 silently wrapping negative numbers around. (Bug#8722)
14971 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
14974 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
14976 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
14978 ccl: Add integer overflow checks.
14979 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
14980 (IN_INT_RANGE): New macros.
14981 (ccl_driver): Use them to check for integer overflow when
14982 decoding a CCL program. Many of the new checks are whether XINT (x)
14983 fits in int; it doesn't always, on 64-bit hosts. The new version
14984 doesn't catch all possible integer overflows, but it's an
14985 improvement. (Bug#8719)
14987 * alloc.c (make_event_array): Use XINT, not XUINT.
14988 There's no need for unsigned here.
14990 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
14991 This follows up to the 2011-05-06 change that substituted uintptr_t
14992 for EMACS_INT. This case wasn't caught back then.
14994 Rework Fformat to avoid integer overflow issues.
14995 * editfns.c: Include <float.h> unconditionally, as it's everywhere
14996 now (part of C89). Include <verify.h>.
14997 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
14998 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
14999 (Fformat): Avoid the prepass trying to compute sizes; it was only
15000 approximate and thus did not catch overflow reliably. Instead, walk
15001 through the format just once, formatting and computing sizes as we go,
15002 checking for integer overflow at every step, and allocating a larger
15003 buffer as needed. Keep track separately whether the format is
15004 multibyte. Keep only the most-recently calculated precision, rather
15005 than them all. Record whether each argument has been converted to
15006 string. Use EMACS_INT, not int, for byte and char and arg counts.
15007 Support field widths and precisions larger than INT_MAX. Avoid
15008 sprintf's undefined behavior with conversion specifications such as %#d
15009 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
15010 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
15011 formatting out-of-range floating point numbers with int
15012 formats. (Bug#8668)
15014 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
15016 * data.c: Avoid integer truncation in expressions involving floats.
15017 * data.c: Include <intprops.h>.
15018 (arith_driver): When there's an integer overflow in an expression
15019 involving floating point, convert the integers to floating point
15020 so that the resulting value does not suffer from catastrophic
15021 integer truncation. For example, on a 64-bit host (* 4
15022 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
15023 Do not rely on undefined behavior after integer overflow.
15025 merge count_size_as_multibyte, parse_str_to_multibyte
15026 * character.c, character.h (count_size_as_multibyte):
15027 Rename from parse_str_to_multibyte; all uses changed.
15028 Check for integer overflow.
15029 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
15030 since it's now a duplicate of the other. This is more of
15031 a character than a buffer op, so better that it's in character.c.
15032 * fns.c, print.c: Adjust to above changes.
15034 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
15036 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
15038 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
15040 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
15041 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
15042 (x_clipboard_manager_save): Now static.
15043 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
15045 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
15046 (crypto_hash_function): Now static.
15047 Fix pointer signedness problems. Avoid unnecessary initializations.
15049 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
15051 * termhooks.h (Vselection_alist): Make it terminal-local.
15053 * terminal.c (create_terminal): Initialize it.
15055 * xselect.c: Support for clipboard managers.
15056 (Vselection_alist): Move to termhooks.h as terminal-local var.
15057 (LOCAL_SELECTION): New macro.
15058 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
15059 (symbol_to_x_atom): Remove gratuitous arg.
15060 (x_handle_selection_request, lisp_data_to_selection_data)
15061 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
15062 (x_own_selection, x_get_local_selection, x_convert_selection):
15063 New arg, specifying work frame. Use terminal-local Vselection_alist.
15064 (some_frame_on_display): Delete unused function.
15065 (Fx_own_selection_internal, Fx_get_selection_internal)
15066 (Fx_disown_selection_internal, Fx_selection_owner_p)
15067 (Fx_selection_exists_p): New optional frame arg.
15068 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
15069 (x_handle_selection_clear): Don't treat other terminals with the
15070 same keyboard specially. Use the terminal-local Vselection_alist.
15071 (x_clear_frame_selections): Use Frun_hook_with_args.
15073 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
15075 * xterm.h: Add support for those atoms.
15077 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
15079 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
15080 (converted_selections, conversion_fail_tag): New global variables.
15081 (x_selection_request_lisp_error): Free the above.
15082 (x_get_local_selection): Remove unnecessary code.
15083 (x_reply_selection_request): Args changed; handle arbitrary array
15084 of converted selections stored in converted_selections.
15085 Separate the XChangeProperty and SelectionNotify steps.
15086 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
15087 (x_convert_selection): New function.
15088 (x_handle_selection_event): Simplify.
15089 (x_get_foreign_selection): Don't ignore incoming requests while
15090 waiting for an answer; this will fail when we implement
15091 SAVE_TARGETS, and seems unnecessary anyway.
15092 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
15093 (Vx_sent_selection_functions): Doc fix.
15095 2011-05-26 Leo Liu <sdl.web@gmail.com>
15097 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
15099 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15101 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
15103 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
15104 for fringe update if it has periodic bitmap.
15105 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
15106 and fringe_bitmap_periodic_p.
15108 * fringe.c (get_fringe_bitmap_data): New function.
15109 (draw_fringe_bitmap_1, update_window_fringes): Use it.
15110 (update_window_fringes): Record periodicity of fringe bitmap in glyph
15111 row. Mark glyph row for fringe update if periodicity changed.
15113 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
15114 for fringe update unless it has periodic bitmap.

15133 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
15134 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
15135 Remove macros that are defined and never used.
15136 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
15138 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
15140 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
15141 (Fx_get_selection_internal): Minor cleanup.

15171 * systime.h (Time): Define only if emacs is defined.
15172 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
15173 where the include path doesn't have X11/X.h by default. See
15174 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
15176 2011-05-20 Kenichi Handa <handa@m17n.org>
15178 * composite.c (find_automatic_composition): Fix previous change.
15180 2011-05-20 Glenn Morris <rgm@gnu.org>
15182 * lisp.mk: New file, split from Makefile.in.
15183 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
15184 (shortlisp): Remove.
15185 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
15187 2011-05-19 Glenn Morris <rgm@gnu.org>
15189 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
15190 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
15191 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
15192 (lisp): Set the order to that of loadup.el.
15193 (shortlisp): Make it a copy of $lisp.
15194 (SOME_MACHINE_LISP): Remove.
15195 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
15196 Use just $shortlisp, not $SOME_MACHINE_LISP too.
15198 2011-05-18 Kenichi Handa <handa@m17n.org>
15200 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
15201 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
15202 (find_automatic_composition): Mostly rewrite for efficiency.
15204 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
15206 * makefile.w32-in: Update dependencies.
15208 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
15210 * menu.c: Include limits.h (fixes the MS-Windows build broken by
15211 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
15213 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
15215 Fix some integer overflow issues, such as string length overflow.
15217 * insdel.c (count_size_as_multibyte): Check for string overflow.
15219 * character.c (lisp_string_width): Check for string overflow.
15220 Use EMACS_INT, not int, for string indexes and lengths; in
15221 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
15222 the resulting string length overflows an EMACS_INT; instead,
15223 report a string overflow if no precision given. When checking for
15224 precision exhaustion, use a check that cannot possibly have
15225 integer overflow. (Bug#8675)
15226 * character.h (lisp_string_width): Adjust to new signature.
15228 * alloc.c (string_overflow): New function.
15229 (Fmake_string): Use it. This doesn't change behavior, but saves
15230 a few bytes and will simplify future changes.
15231 * character.c (string_escape_byte8): Likewise.
15232 * lisp.h (string_overflow): New decl.
15234 Fixups, following up to the user-interface timestamp change.
15235 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
15236 for UI timestamps, instead of unsigned long.
15237 * msdos.c (mouse_get_pos): Likewise.
15238 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
15239 * w32gui.h (Time): Define by including "systime.h" rather than by
15240 declaring it ourselves. (Bug#8664)
15242 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
15243 * image.c (clear_image_cache): Likewise.
15245 * term.c (term_mouse_position): Don't assume time_t wraparound.
15247 Be more systematic about user-interface timestamps.
15248 Before, the code sometimes used 'Time', sometimes 'unsigned long',
15249 and sometimes 'EMACS_UINT', to represent these timestamps.
15250 This change causes it to use 'Time' uniformly, as that's what X uses.
15251 This makes the code easier to follow, and makes it easier to catch
15252 integer overflow bugs such as Bug#8664.
15253 * frame.c (Fmouse_position, Fmouse_pixel_position):
15254 Use Time, not unsigned long, for user-interface timestamps.
15255 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
15256 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
15257 * keyboard.h (last_event_timestamp): Likewise.
15258 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
15259 * menu.h (xmenu_show): Likewise.
15260 * term.c (term_mouse_position): Likewise.
15261 * termhooks.h (struct input_event.timestamp): Likewise.
15262 (struct terminal.mouse_position_hook): Likewise.
15263 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
15264 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
15265 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
15266 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
15267 what it was before.
15268 * menu.h, termhooks.h: Include "systime.h", for Time.
15270 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
15271 Don't assume that the difference between two unsigned long values
15272 can fit into an integer. At this point, we know button_down_time
15273 <= event->timestamp, so the difference must be nonnegative, so
15274 there's no need to cast the result if double-click-time is
15275 nonnegative, as it should be; check that it's nonnegative, just in
15276 case. This bug is triggered when events are more than 2**31 ms
15277 apart (about 25 days). (Bug#8664)
15279 * xselect.c (last_event_timestamp): Remove duplicate decl.
15280 (x_own_selection): Remove needless cast to unsigned long.
15282 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
15283 that always fit in int. Use a sentinel instead of a counter, to
15284 avoid a temp and to allay GCC's concerns about possible int overflow.
15285 * frame.h (struct frame): Use int for menu_bar_items_used
15286 instead of EMACS_INT, since it always fits in int.
15288 * menu.c (grow_menu_items): Check for int overflow.
15290 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
15292 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
15293 Before, the code was not consistent. These values cannot exceed
15294 2**31 - 1 so there's no need to make them unsigned.
15295 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
15296 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
15297 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
15299 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
15301 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
15302 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
15303 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
15304 presumably because the widths might not match.
15306 * window.c (size_window): Avoid needless test at loop start.
15308 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
15310 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
15312 2011-05-12 Drew Adams <drew.adams@oracle.com>
15314 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
15316 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15318 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
15319 `width' to `bar_area_x' and `bar_area_width', respectively.
15320 (x_scroll_run): Take account of fringe background extension.
15322 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
15323 Rename local vars `left' and `width' to `bar_area_x' and
15324 `bar_area_width', respectively.
15325 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
15326 background extension.
15328 2011-05-10 Jim Meyering <meyering@redhat.com>
15330 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
15332 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
15334 * image.c (Finit_image_library): Return t for built-in image types,
15335 like pbm and xbm. (Bug#8640)
15337 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
15339 * w32menu.c (set_frame_menubar): Fix submenu allocation.
15341 2011-05-07 Eli Zaretskii <eliz@gnu.org>
15343 * w32console.c (Fset_screen_color): Doc fix.
15344 (Fget_screen_color): New function.
15345 (syms_of_ntterm): Defsubr it.
15347 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
15348 unlink the temporary file if Fcall_process didn't create it in the
15350 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
15351 child process will be redirected to a file specified with `:file'.
15352 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
15353 cue to call_process_cleanup not to close that handle.
15355 2011-05-07 Ben Key <bkey76@gmail.com>
15357 * makefile.w32-in: The bootstrap-temacs rule now makes use of
15358 one of two shell specific rules, either bootstrap-temacs-CMD or
15359 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
15360 to the previous implementation of the bootstrap-temacs rule.
15361 The bootstrap-temacs-CMD rule is similar to the previous
15362 implementation of the bootstrap-temacs rule except that it
15363 makes use of the ESC_CFLAGS variable instead of the CFLAGS
15366 These changes, along with some changes to nt/configure.bat,
15367 nt/gmake.defs, and nt/nmake.defs, are required to extend my
15368 earlier fix to add support for --cflags and --ldflags options
15369 that include quotes so that it works whether make uses cmd or
15372 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
15374 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
15375 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
15377 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
15378 a string. Handle both cases.
15379 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
15380 (Fdbus_register_method): Use Qinvalid_function.
15382 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
15384 * makefile.w32-in: Update dependencies.
15385 (LISP_H): Add inttypes.h and stdin.h.
15386 (PROCESS_H): Add unistd.h.
15388 2011-05-06 Eli Zaretskii <eliz@gnu.org>
15390 * lread.c: Include limits.h (fixes the MS-Windows build broken by
15391 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
15393 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
15395 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
15397 * term.c (vfatal): Remove stray call to va_end.
15398 It's not needed and the C Standard doesn't allow it here anyway.
15400 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
15401 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
15403 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
15406 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
15408 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15410 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
15412 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
15414 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
15416 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
15417 * charset.c (Fdefine_charset_internal): Don't initialize
15418 charset.code_space[15]. The value was garbage, on hosts with
15419 32-bit int (Bug#8600).
15421 * lread.c (read_integer): Be more consistent with string-to-number.
15422 Use string_to_number to do the actual conversion; this avoids
15423 rounding errors and fixes some other screwups. Without this fix,
15424 for example, #x1fffffffffffffff was misread as -2305843009213693952.
15425 (digit_to_number): Move earlier, for benefit of read_integer.
15426 Return -1 if the digit is out of range for the base, -2 if it is
15427 not a digit in any supported base. (Bug#8602)
15429 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
15431 * dispnew.c (scrolling_window): Return 1 if we scrolled,
15432 to match comment at start of function. This also removes a
15433 GCC warning about overflow in a 32+64-bit port.
15435 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
15437 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
15438 Reported by Stefan Monnier in
15439 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
15440 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
15441 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
15443 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
15444 (EMACS_UINTPTR): Likewise, with uintptr_t.
15446 * lisp.h: Prefer 64-bit EMACS_INT if available.
15447 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
15448 on 32-bit hosts that have 64-bit int, so that they can access
15450 However, temporarily disable this change unless the temporary
15451 symbol WIDE_EMACS_INT is defined.
15453 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
15455 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
15456 This removes an assumption that EMACS_INT and long are the same
15457 width as pointers. The assumption is true for Emacs porting targets
15458 now, but we want to make other targets possible.
15459 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
15460 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
15461 In the rest of the code, change types of integers that hold casted
15462 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
15463 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
15464 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
15465 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
15466 No need to cast type when ORing.
15467 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
15468 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
15469 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
15470 assume EMACS_INT is the same width as char *.
15471 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
15472 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
15473 Remove no-longer-needed casts.
15474 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
15475 (xg_tool_bar_help_callback, xg_make_tool_item):
15476 Use EMACS_INTPTR to hold an integer
15477 that will be cast to void *; this can avoid a GCC warning
15478 if EMACS_INT is not the same width as void *.
15479 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
15480 * xdisp.c (display_echo_area_1, resize_mini_window_1):
15481 (current_message_1, set_message_1):
15482 Use a local to convert to proper width without a cast.
15483 * xmenu.c (dialog_selection_callback): Likewise.
15485 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
15486 Also, don't assume VALBITS / RAND_BITS is less than 5,
15487 and don't rely on undefined behavior when shifting a 1 left into
15489 * lisp.h (get_random): Change signature to match.
15491 * lread.c (hash_string): Use size_t, not int, for hash computation.
15492 Normally we prefer signed values; but hashing is special, because
15493 it's better to use unsigned division on hash table sizes so that
15494 the remainder is nonnegative. Also, size_t is the natural width
15495 for hashing into memory. The previous code used 'int', which doesn't
15496 retain enough info to hash well into very large tables.
15497 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
15499 * dbusbind.c: Don't possibly lose pointer info when converting.
15500 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
15501 Use XPNTR rather than XHASH, so that the high-order bits of
15502 the pointer aren't lost when converting through void *.
15504 * eval.c (Fautoload): Don't double-shift a pointer.
15506 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
15508 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
15510 * gnutls.c (DEF_GNUTLS_FN):
15511 * image.c (DEF_IMGLIB_FN): Make function pointers static.
15513 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
15515 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
15518 2011-05-05 Eli Zaretskii <eliz@gnu.org>
15520 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
15521 New version that can reserve upto 2GB of heap space.
15523 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
15525 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
15527 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
15529 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
15530 `gnutls_certificate_set_x509_key_file'.
15532 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
15534 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
15535 Update dependencies.
15537 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15539 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
15540 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
15541 Remove unused parameter `fildes'.
15542 * process.c (read_process_output, send_process): Don't pass it.
15544 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15546 Fix previous change: the library cache is defined in w32.c.
15547 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
15548 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
15550 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15552 Implement dynamic loading of GnuTLS on Windows.
15554 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
15555 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
15556 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
15559 * gnutls.c (Qgnutls_dll): Define.
15560 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
15561 (gnutls_*): Declare function pointers.
15562 (init_gnutls_functions): New function to initialize function pointers.
15563 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
15564 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
15565 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
15566 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
15567 (emacs_gnutls_write, emacs_gnutls_read)
15568 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
15569 (Fgnutls_available_p): New function.
15570 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
15571 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
15572 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
15574 * image.c: Include w32.h.
15575 (Vimage_type_cache): Delete.
15576 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
15577 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
15578 (w32_delayed_load): Move to w32.c.
15580 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
15582 * w32.c (QCloaded_from, Vlibrary_cache): Define.
15583 (w32_delayed_load): Move from image.c. When loading a library, record
15584 its filename in the :loaded-from property of the library id.
15585 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
15586 Initialize and staticpro them.
15587 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
15589 * process.c: Include lisp.h before w32.h, not after.
15590 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
15591 instead of gnutls_record_check_pending.
15593 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
15595 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
15597 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
15598 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists

15643 rather than `XVECTOR (FOO)->size'.
15645 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
15646 inttypes.h, as a gnulib replacement is used if it not available in
15649 2011-04-21 Eli Zaretskii <eliz@gnu.org>
15651 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.

15661 charbuf for the composition carryover bytes.
15663 2011-04-21 Eli Zaretskii <eliz@gnu.org>

15668 %llo or %llx format is passed. (Bug#8545)
15670 * window.c (window_scroll_line_based): Use a marker instead of
15671 simple variables to record original value of point. (Bug#7952)
15673 * doprnt.c (doprnt): Fix the case where a multibyte sequence
15674 produced by %s or %c overflows available buffer space. (Bug#8545)
15676 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
15678 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
15679 (SIZE_MAX): Move defn after all includes, as they might #define it.
15681 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15683 * w32.c (init_environment): Warn about defaulting HOME to C:\.
15685 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15687 * keyboard.c (Qdelayed_warnings_hook): Define.
15688 (command_loop_1): Run `delayed-warnings-hook'
15689 if Vdelayed_warnings_list is non-nil.
15690 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
15691 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
15693 2011-04-28 Eli Zaretskii <eliz@gnu.org>
15695 * doprnt.c (doprnt): Don't return value smaller than the buffer
15696 size if the message was truncated. (Bug#8545).
15698 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15700 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
15701 (Fx_window_property): #if-0 the whole functions, not just the bodies.
15703 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15705 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
15707 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
15709 * makefile.w32-in: Update dependencies.
15711 2011-04-27 Eli Zaretskii <eliz@gnu.org>
15713 Improve `doprnt' and its usage. (Bug#8545)
15714 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
15715 `format_end'. Remove support for %l as a conversion specifier.
15716 Don't use xrealloc. Improve diagnostics when the %l size modifier
15717 is used. Update the commentary.
15719 * eval.c (verror): Simplify calculation of size_t.
15721 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
15724 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
15726 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
15729 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15731 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
15732 This makes this file independent of the recent pseudovector change.
15734 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
15736 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
15738 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
15739 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
15740 Remove unused local.
15741 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
15743 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
15744 GCC 4.6.0 optimizes based on type-based alias analysis.
15745 For example, if b is of type struct buffer * and v of type struct
15746 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
15747 != &v->size, and therefore "v->size = 1; b->size = 2; return
15748 v->size;" must therefore return 1. This assumption is incorrect
15749 for Emacs, since it type-puns struct Lisp_Vector * with many other
15750 types. To fix this problem, this patch adds a new type struct
15751 vectorlike_header that documents the constraints on layout of vectors
15752 and pseudovectors, and helps optimizing compilers not get fooled
15753 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
15754 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
15755 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
15757 (XSETPVECTYPE): Rewrite in terms of new macro.
15758 (XSETPVECTYPESIZE): New macro, specifying both type and size.
15759 This is a bit clearer, and further avoids the possibility of
15760 undesirable aliasing.
15761 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
15762 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
15763 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
15764 since Lisp_Subr is a special case (no "next" field).
15765 (ASIZE): Now uses header.size rather than size.
15766 All previous uses of XVECTOR (foo)->size replaced to use this macro,
15767 to avoid the hassle of writing XVECTOR (foo)->header.size.
15768 (struct vectorlike_header): New type.
15769 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
15770 object, to help avoid aliasing.
15771 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
15772 (SUBRP): Likewise, since Lisp_Subr is a special case.
15773 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
15774 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
15775 (struct Lisp_Hash_Table): Combine first two members into a single
15776 struct vectorlike_header member. All uses of "size" and "next" members
15777 changed to be "header.size" and "header.next".
15778 * buffer.h (struct buffer): Likewise.
15779 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
15780 * frame.h (struct frame): Likewise.
15781 * process.h (struct Lisp_Process): Likewise.
15782 * termhooks.h (struct terminal): Likewise.
15783 * window.c (struct save_window_data, struct saved_window): Likewise.
15784 * window.h (struct window): Likewise.
15785 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
15786 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
15787 * buffer.c (init_buffer_once): Likewise.
15788 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
15790 * process.c (Fformat_network_address): Use local var for size,
15793 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
15795 Make the Lisp reader and string-to-float more consistent (Bug#8525)
15796 * data.c (atof): Remove decl; no longer used or needed.
15797 (digit_to_number): Move to lread.c.
15798 (Fstring_to_number): Use new string_to_number function, to be
15799 consistent with how the Lisp reader treats infinities and NaNs.
15800 Do not assume that floating-point numbers represent EMACS_INT
15801 without losing information; this is not true on most 64-bit hosts.
15802 Avoid double-rounding errors, by insisting on integers when
15803 parsing non-base-10 numbers, as the documentation specifies.
15804 * lisp.h (string_to_number): New decl, replacing ...
15805 (isfloat_string): Remove.
15806 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
15807 (read1): Do not accept +. and -. as integers; this
15808 appears to have been a coding error. Similarly, do not accept
15809 strings like +-1e0 as floating point numbers. Do not report
15810 overflow for integer overflows unless the base is not 10 which
15811 means we have no simple and reliable way to continue.
15812 Break out the floating-point parsing into a new
15813 function string_to_number, so that Fstring_to_number parses
15814 floating point numbers consistently with the Lisp reader.
15815 (digit_to_number): Move here from data.c. Make it static inline.
15816 (E_CHAR, EXP_INT): Remove, replacing with ...
15817 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
15818 (string_to_number): New function, replacing isfloat_string.
15819 This function checks for valid syntax and produces the resulting
15820 Lisp float number too. Rework it so that string-to-number
15821 no longer mishandles examples like "1.0e+". Use strtoumax,
15822 so that overflow for non-base-10 numbers is reported only when
15823 there's no portable and simple way to convert to floating point.
15825 * textprop.c (set_text_properties_1): Rewrite for clarity,
15826 and to avoid GCC warning about integer overflow.
15828 * intervals.h (struct interval): Use EMACS_INT for members
15829 where EMACS_UINT might cause problems. See
15830 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
15831 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
15832 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
15834 (offset_intervals): Tell GCC not to worry about length overflow
15835 when negating a negative length.
15837 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
15838 (overrun_check_free): Likewise.
15840 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
15841 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
15844 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15845 (gnutls_make_error): Rename local to avoid shadowing.
15846 (gnutls_emacs_global_deinit): ifdef out; not used.
15847 (Fgnutls_boot): Use const for pointer to readonly storage.
15848 Comment out unused local. Fix pointer signedness problems.
15850 * lread.c (openp): Don't stuff size_t into an 'int'.
15851 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
15852 about possible signed overflow.
15854 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15855 (GDK_KEY_g): Don't define if already defined.
15856 (xg_prepare_tooltip): Avoid pointer signedness problem.
15857 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
15859 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
15860 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
15862 * xfns.c (Fx_window_property): Simplify a bit,
15863 to make a bit faster and to avoid GCC 4.6.0 warning.
15864 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
15866 * fns.c (internal_equal): Don't assume size_t fits in int.
15868 * alloc.c (compact_small_strings): Tighten assertion a little.
15870 Replace pEd with more-general pI, and fix some printf arg casts.
15871 * lisp.h (pI): New macro, generalizing old pEd macro to other
15872 conversion specifiers. For example, use "...%"pI"d..." rather
15873 than "...%"pEd"...".
15874 (pEd): Remove. All uses replaced with similar uses of pI.
15875 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
15876 * alloc.c (check_pure_size): Don't overflow by converting size to int.
15877 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
15878 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
15879 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
15880 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
15881 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
15883 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
15884 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
15885 * print.c (safe_debug_print, print_object): Likewise.
15886 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
15888 Use pI instead of if-then-else-abort. Use %p to avoid casts,
15889 avoiding the 0 flag, which is not portable.
15890 * process.c (Fmake_network_process): Use pI to avoid cast.
15891 * region-cache.c (pp_cache): Likewise.
15892 * xdisp.c (decode_mode_spec): Likewise.
15893 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
15894 behavior on 64-bit hosts with printf arg.
15895 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
15896 (x_stop_queuing_selection_requests): Likewise.
15897 (x_get_window_property): Don't truncate byte count to an 'int'
15900 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
15901 here, since it parses constructs like leading '-' and spaces,
15902 which are not wanted; and it overflows with large numbers.
15903 Instead, simply match F[0-9]+, which is what is wanted anyway.
15905 * alloc.c: Remove unportable assumptions about struct layout.
15906 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
15907 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
15908 (allocate_vectorlike, make_pure_vector): Use the new macros,
15909 plus offsetof, to remove unportable assumptions about struct layout.
15910 These assumptions hold on all porting targets that I know of, but
15911 they are not guaranteed, they're easy to remove, and removing them
15912 makes further changes easier.
15914 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
15915 This doesn't fix a bug but makes the code clearer.
15916 (string_overrun_cookie): Now const. Use initializers that
15917 don't formally overflow signed char, to avoid warnings.
15918 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
15919 can cause Emacs to crash when string overrun checking is enabled.
15920 (allocate_buffer): Don't assume sizeof (struct buffer) is a
15921 multiple of sizeof (EMACS_INT); it need not be, if
15922 alignof(EMACS_INT) < sizeof (EMACS_INT).
15923 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
15925 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

15937 * lisp.h (Qdebug): List symbol.
15938 * eval.c (Qdebug): Restore global linkage.
15939 * keyboard.c (debug-on-event): New variable.
15940 (handle_user_signal): Break into debugger when debug-on-event
15941 matches the current signal symbol.
15943 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
15945 * alloc.c (check_sblock, check_string_bytes)
15946 (check_string_free_list): Convert to standard C.
15948 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
15950 * w32.c (emacs_gnutls_push): Fix typo.
15952 2011-04-25 Eli Zaretskii <eliz@gnu.org>
15954 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
15955 "cast to pointer from integer of different size".
15957 Improve doprnt and its use in verror. (Bug#8545)
15958 * doprnt.c (doprnt): Document the set of format control sequences
15959 supported by the function. Use SAFE_ALLOCA instead of always
15962 * eval.c (verror): Don't limit the buffer size at size_max-1, that
15963 is one byte too soon. Don't use xrealloc; instead xfree and
15966 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
15968 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
15971 * gnutls.c: Renamed global_initialized to
15972 gnutls_global_initialized. Added internals for the
15973 :verify-hostname-error, :verify-error, and :verify-flags
15974 parameters of `gnutls-boot' and documented those parameters in the
15975 docstring. Start callback support.
15976 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
15977 unless a fatal error occurred. Call gnutls_alert_send_appropriate
15978 on error. Return error code.
15979 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
15980 (emacs_gnutls_read): Likewise.
15981 (Fgnutls_boot): Return handshake error code.
15982 (emacs_gnutls_handle_error): New function.
15983 (wsaerror_to_errno): Likewise.
15985 * w32.h (emacs_gnutls_pull): Add prototype.
15986 (emacs_gnutls_push): Likewise.
15988 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
15989 (emacs_gnutls_push): Likewise.
15991 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
15993 * process.c (wait_reading_process_output): Check if GnuTLS
15994 buffered some data internally if no FDs are set for TLS
15997 * makefile.w32-in (OBJ2): Add gnutls.$(O).
15998 (LIBS): Link to USER_LIBS.
15999 ($(BLD)/gnutls.$(0)): New target.

16003 * xdisp.c (handle_single_display_spec): Rename the
16004 display_replaced_before_p argument into display_replaced_p, to
16005 make it consistent with the commentary. Fix typos in the
16008 * textprop.c (syms_of_textprop): Remove dead code.
16009 (copy_text_properties): Delete obsolete commentary about an
16010 interface that was deleted long ago. Fix typos in the description

16014 to changes in oldXMenu/XMenu.h from 2011-04-16.
16015 <menu_help_message, prev_menu_help_message>: Constify.
16016 (IT_menu_make_room): menu->help_text is now `const char **';

16081 codepoint of an invalid character, to avoid displaying a bogus
16084 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
16085 `error', not SYMBOL_NAME itself.

16090 * charset.c (check_iso_charset_parameter): Fix incorrect argument
16091 to `error' in error message about FINAL_CHAR argument. Make sure
16092 FINAL_CHAR is a character, and use %c when it is passed as
16093 argument to `error'.
16095 2011-04-23 Eli Zaretskii <eliz@gnu.org>
16097 * s/ms-w32.h (localtime): Redirect to sys_localtime.

16283 ns_descriptor_to_entity that were caused by using free to
16284 deallocate memory blocks that were allocated by xmalloc (via

16305 (emacs_read, emacs_write): Use it.
16306 * process.c (send_process): Adjust to the new signatures of
16307 emacs_write and emacs_gnutls_write. Do not attempt to store

16500 * font.c (font_close_object): Now static.
16501 * font.h (font_close_object): Remove.
16502 * fontset.c (FONTSET_OBJLIST): Remove.
16503 (free_realized_fontset) #if-0 the body, which does nothing.
16504 (face_suitable_for_char_p): #if-0, as it's never called.
16505 * fontset.h (face_suitable_for_char_p): Remove decl.
16506 * xfaces.c (face_at_string_position):
16507 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
16508 since 0 is always ASCII.
16510 * fns.c (weak_hash_tables): Now static.
16512 * fileio.c: Make symbols static if they're not exported.

16531 * editfns.c, lisp.h (get_operating_system_release): Remove.
16532 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
16533 worth the hassle of breaking this out.
16535 * xterm.c: Make symbols static if they're not exported.
16536 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

16639 * buffer.c (buffer_count): Remove unused var.

16648 * atimer.h (run_all_atimers): Remove; not exported.
16650 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
16651 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
16652 was inaccessible from Lisp.
16653 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
16654 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
16656 alloc.c: Import and export fewer symbols, and remove unused items.
16657 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
16659 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
16660 it's not optimized away by whole-program optimization.

16662 (catchlist, handlerlist, mark_backtrace):
16663 Declare only if BYTE_MARK_STACK.

16672 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
16673 (mark_backtrace): Define only if BYTE_MARK_STACK.
16674 * xdisp.c (message_enable_multibyte): Now static.
16676 Declare Lisp_Object Q* variables to be 'static' if not exported.
16677 This makes it easier for human readers (and static analyzers)
16678 to see whether these variables are used from other modules.
16679 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
16680 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

16689 Remove decls of unexported vars.
16690 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
16692 * lisp.h (DEFINE_FUNC): Make sname 'static'.
16694 Make Emacs functions such as Fatom 'static' by default.
16695 This makes it easier for human readers (and static analyzers)
16696 to see whether these functions can be called from other modules.
16697 DEFUN now defines a static function. To make the function external
16698 so that it can be used in other C modules, use the new macro DEFUE.
16699 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
16700 (Finit_image_library):
16701 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
16702 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
16703 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
16704 Remove decls, since these functions are now static.
16705 (Funintern, Fget_internal_run_time): New decls, since these functions
16706 were already external.
16708 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

16715 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
16716 Mark functions with DEFUE instead of DEFUN,
16717 if they are used in other modules.
16718 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
16719 decls for now-static functions.
16720 * buffer.h (Fdelete_overlay): Remove decl.
16721 * callproc.c (Fgetenv_internal): Mark as internal.

16730 * image.c (Finit_image_library): New forward static decl.
16731 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
16732 * intervals.h (Fprevious_property_change):
16733 (Fremove_list_of_text_properties): Remove decls.
16734 * keyboard.c (Fthis_command_keys): Remove decl.
16735 (Fcommand_execute): New forward static decl.

16756 2011-04-13 Eli Zaretskii <eliz@gnu.org>
16758 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
16759 when at ZV. (Bug#8487)
16761 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
16763 * charset.c (Fclear_charset_maps): Use xfree instead of free.

16766 * sound.c (sound_cleanup, alsa_close): Likewise.
16767 * termcap.c (tgetent): Likewise.
16768 * xfns.c (x_default_font_parameter): Likewise.
16769 * xsettings.c (read_and_apply_settings): Likewise.
16771 * alloc.c (overrun_check_malloc, overrun_check_realloc)
16772 (overrun_check_free): Protoize.
16774 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
16776 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
16777 since callers should never pass a negative size.
16778 Change the signature to match that of plain 'read' and 'write'; see
16779 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
16780 * lisp.h: Update prototypes of emacs_write and emacs_read.
16782 2011-04-11 Eli Zaretskii <eliz@gnu.org>
16784 * xdisp.c (redisplay_window): Don't try to determine the character
16785 position of the scroll margin if the window start point w->startp
16786 is outside the buffer's accessible region. (Bug#8468)
16788 2011-04-10 Eli Zaretskii <eliz@gnu.org>
16790 Fix write-region and its subroutines for buffers > 2GB.
16791 * fileio.c (a_write, e_write): Modify declaration of arguments and
16792 local variables to support buffers larger than 2GB.
16793 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
16795 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
16796 argument, local variables, and return value.
16798 * lisp.h: Update prototypes of emacs_write and emacs_read.
16800 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
16802 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
16804 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
16806 Fix more problems found by GCC 4.6.0's static checks.
16808 * xdisp.c (vmessage): Use a better test for character truncation.
16810 * charset.c (load_charset_map): <, not <=, for optimization,
16811 and to avoid potential problems with integer overflow.
16812 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
16813 * casetab.c (set_identity, shuffle): Likewise.
16814 * editfns.c (Fformat): Likewise.
16815 * syntax.c (skip_chars): Likewise.
16817 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
16818 This also lets GCC 4.6.0 generate slightly better loop code.
16820 * callint.c (Fcall_interactively): <, not <=, for optimization.
16821 (Fcall_interactively): Count the number of arguments produced,
16822 not the number of arguments given. This is simpler and lets GCC
16823 4.6.0 generate slightly better code.
16825 * ftfont.c: Distingish more carefully between FcChar8 and char.
16826 The previous code passed unsigned char * to a functions like
16827 strlen and xstrcasecmp that expect char *, which does not
16828 conform to the C standard.
16829 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
16830 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
16831 char * when the C standard requires it.
16833 * keyboard.c (read_char): Remove unused var.
16835 * eval.c: Port to Windows vsnprintf (Bug#8435).
16836 Include <limits.h>.
16837 (SIZE_MAX): Define if the headers do not.
16838 (verror): Do not give up if vsnprintf returns a negative count.
16839 Instead, grow the buffer. This ports to Windows vsnprintf, which
16840 does not conform to C99. Problem reported by Eli Zaretskii.
16841 Also, simplify the allocation scheme, by avoiding the need for
16842 calling realloc, and removing the ALLOCATED variable.
16844 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
16846 Remove invocations of doprnt, as Emacs now uses vsnprintf.
16847 But keep the doprint source code for now, as we might revamp it
16848 and use it again (Bug#8435).
16849 * lisp.h (doprnt): Remove.
16850 * Makefile.in (base_obj): Remove doprnt.o.
16851 * deps.mk (doprnt.o): Remove.
16853 error: Print 32- and 64-bit integers portably (Bug#8435).
16854 Without this change, on typical 64-bit hosts error ("...%d...", N)
16855 was used to print both 32- and 64-bit integers N, which relied on
16856 undefined behavior.
16857 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
16858 * lisp.h (error, verror): Mark as printf-like functions.
16859 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
16860 Report overflow in size calculations when allocating printf buffer.
16861 Do not truncate output string at its first null byte.
16862 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
16863 Truncate the output at a character boundary, since vsnprintf does not
16865 * charset.c (check_iso_charset_parameter): Convert internal
16866 character to string before calling 'error', since %c now has the
16868 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
16869 overflow when computing char to be passed to 'error'. Do not
16870 pass Lisp_Object to 'error'; pass the integer instead.
16871 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
16872 formatted with plain %d.
16874 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
16876 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
16878 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
16880 * xterm.c (x_catch_errors): Remove duplicate declaration.
16882 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
16884 * xdisp.c, lisp.h (message_nolog): Remove; unused.
16886 2011-04-10 Jim Meyering <meyering@redhat.com>
16888 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
16889 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
16890 return ssize_t not "int", and use size_t as the buffer length.
16891 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
16892 * gnutls.h: Update declarations.
16893 * process.c (read_process_output): Use ssize_t, to match.
16894 (send_process): Likewise.
16896 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16898 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
16900 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16902 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):

16910 2011-04-09 Eli Zaretskii <eliz@gnu.org>
16912 Fix some uses of `int' instead of EMACS_INT.
16913 * search.c (string_match_1, fast_string_match)
16914 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
16915 (scan_buffer, find_next_newline_no_quit)

17006 * eval.c (Fsignal): Remove excess argument to 'fatal'.
17008 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
17009 This avoids several warnings with gcc -Wstrict-overflow.
17010 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
17011 directly, rather than having caller test rule sign. This avoids
17012 some unnecessary tests.
17013 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
17014 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
17015 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
17017 * xfont.c (xfont_text_extents): Remove var that was set but not used.
17018 (xfont_open): Avoid unnecessary tests.
17020 * composite.c (composition_gstring_put_cache): Use unsigned integer.
17022 * composite.h, composite.c (composition_gstring_put_cache):
17023 Use EMACS_INT, not int, for length.
17025 * composite.h (COMPOSITION_DECODE_REFS): New macro,
17026 breaking out part of COMPOSITION_DECODE_RULE.
17027 (COMPOSITION_DECODE_RULE): Use it.
17028 * composite.c (get_composition_id): Remove unused local vars,
17029 by using the new macro.
17031 * textprop.c (set_text_properties_1): Change while to do-while,
17032 since the condition is always true at first.
17034 * intervals.c (graft_intervals_into_buffer): Mark var as used.
17035 (interval_deletion_adjustment): Return unsigned value.
17038 * process.c (list_processes_1, create_pty, read_process_output):

17054 * print.c (print_error_message): Avoid int overflow.
17056 * font.c (font_list_entities): Redo for clarity,
17057 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
17059 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
17060 (font_score): Avoid potential overflow in diff calculation.

17063 (sxhash): Redo loop for clarity and to avoid wraparound warning.
17065 * eval.c (funcall_lambda): Rename local to avoid shadowing.
17067 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
17068 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
17069 can always succeed if overflow has undefined behavior.
17071 * search.c (boyer_moore, wordify): Remove vars set but not used.
17072 (wordify): Omit three unnecessary tests.
17074 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

17083 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
17084 (Finsert_file_contents): Remove unnecessary code checking fd.
17086 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
17087 Check for integer overflow on size calculations.
17089 * buffer.c (Fprevious_overlay_change): Remove var that is set
17092 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
17093 Remove vars that are set but not used.
17094 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
17095 (timer_check_2): Mark vars as initialized.
17097 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
17099 * image.c (lookup_image): Remove var that is set but not used.
17100 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
17102 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
17103 that are set but not used.
17105 * xfns.c (make_invisible_cursor): Don't return garbage
17106 if XCreateBitmapFromData fails (Bug#8410).
17108 * xselect.c (x_get_local_selection, x_handle_property_notify):
17109 Remove vars that are set but not used.
17111 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
17112 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
17114 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
17115 Remove var that is set but not used.
17116 (scroll_bar_windows_size): Now size_t, not int.
17117 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
17118 Check for overflow.
17120 * xfaces.c (realize_named_face): Remove vars that are set but not used.
17121 (map_tty_color) [!defined MSDOS]: Likewise.
17123 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
17125 * coding.c: Remove vars that are set but not used.
17126 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
17127 All callers changed.
17128 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
17129 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
17130 (decode_coding_charset): Remove vars that are set but not used.
17132 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
17133 that is set but not used.
17135 * print.c (print_object): Remove var that is set but not used.
17137 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
17138 The gnulib version avoids calling malloc in the usual case,
17139 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
17140 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
17141 * filelock.c (current_lock_owner): Likewise.
17142 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
17143 * sysdep.c: Include allocator.h, careadlinkat.h.
17144 (emacs_no_realloc_allocator): New static constant.
17145 (emacs_readlink): New function.
17146 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
17147 ../lib/careadlinkat.h.
17149 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
17151 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
17152 first non-nil return value).

17156 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
17157 if not defined (Bug#8403).
17159 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
17161 * xdisp.c (display_count_lines): Remove parameter `start',
17162 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
17163 (get_char_face_and_encoding): Remove parameter `multibyte_p',
17164 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

17166 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
17167 and thereabouts. All callers changed.
17168 (get_per_char_metric): Remove parameter `f', unused since
17169 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
17171 2011-04-02 Jim Meyering <meyering@redhat.com>
17173 do not dereference NULL upon failed strdup
17174 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
17175 (ns_get_family): Likewise.
17177 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
17179 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
17181 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
17183 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
17186 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
17188 Add lexical binding.
17190 * window.c (Ftemp_output_buffer_show): New fun.
17191 (Fsave_window_excursion):
17192 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
17194 * lread.c (lisp_file_lexically_bound_p): New function.
17195 (Fload): Bind Qlexical_binding.
17196 (readevalloop): Remove `evalfun' arg.
17197 Bind Qinternal_interpreter_environment.
17198 (Feval_buffer): Bind Qlexical_binding.
17199 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
17201 (syms_of_lread): Declare `lexical-binding'.
17203 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
17205 * keyboard.c (eval_dyn): New fun.
17206 (menu_item_eval_property): Use it.
17208 * image.c (parse_image_spec): Use Ffunctionp.
17210 * fns.c (concat, mapcar1): Accept byte-code-functions.
17212 * eval.c (Fsetq): Handle lexical vars.
17213 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
17214 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
17215 (FletX, Flet): Obey lexical binding.
17216 (Fcommandp): Handle closures.
17217 (Feval): New `lexical' arg.
17218 (eval_sub): New function extracted from Feval. Use it almost
17219 everywhere where Feval was used. Look up vars in lexical env.
17221 (Ffunctionp): Move from subr.el.
17222 (Ffuncall): Handle closures.
17223 (apply_lambda): Remove `eval_flags'.
17224 (funcall_lambda): Handle closures and new byte-code-functions.
17225 (Fspecial_variable_p): New function.
17226 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
17227 but without exporting it to Lisp.
17229 * doc.c (Fdocumentation, store_function_docstring):
17230 * data.c (Finteractive_form): Handle closures.
17232 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
17235 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
17237 (exec_byte_code): New function extracted from Fbyte_code to handle new
17238 calling convention for byte-code-functions. Add new byte-codes.
17240 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
17242 * alloc.c (Fmake_symbol): Init new `declared_special' field.
17244 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
17246 * xdisp.c (redisplay_internal): Fix prototype.
17248 2011-03-31 Eli Zaretskii <eliz@gnu.org>
17250 * xdisp.c (SCROLL_LIMIT): New macro.
17251 (try_scrolling): Use it when setting scroll_limit.
17252 Limit scrolling to 100 screen lines.
17253 (redisplay_window): Even when falling back on "recentering",
17254 position point in the window according to scroll-conservatively,
17255 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
17257 (try_scrolling): When point is above the window, allow searching
17258 as far as scroll_max, or one screenful, to compute vertical
17259 distance from PT to the scroll margin position. This prevents
17260 try_scrolling from unnecessarily failing when
17261 scroll-conservatively is set to a value slightly larger than the
17262 window height. Clean up the case of PT below the margin at bottom
17263 of window: scroll_max can no longer be INT_MAX. When aggressive
17264 scrolling is in use, don't let point enter the opposite scroll
17265 margin as result of the scroll.
17266 (syms_of_xdisp) <scroll-conservatively>: Document the
17267 threshold of 100 lines for never-recentering scrolling.
17269 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
17271 * dispextern.h (move_it_by_lines):
17272 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
17273 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
17274 (message_log_check_duplicate): Remove parameters `prev_bol' and
17275 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
17276 (redisplay_internal): Remove parameter `preserve_echo_area',
17277 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
17279 * indent.c (Fvertical_motion):
17280 * window.c (window_scroll_pixel_based, Frecenter):
17281 Don't pass `need_y_p' to `move_it_by_lines'.
17283 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
17285 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
17286 steal a few bits to be more compact.
17287 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
17288 Remove unneeded casts.
17290 * bytecode.c (Fbyte_code): CAR and CDR can GC.
17292 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
17294 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
17295 binding" message (bug#7967).
17297 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
17299 Fix more problems found by GCC 4.6.0's static checks.
17301 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
17302 Remove unused local var.
17304 * editfns.c (Fmessage_box): Remove unused local var.
17306 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
17307 (note_mode_line_or_margin_highlight, note_mouse_highlight):
17308 Omit unused local vars.
17309 * window.c (shrink_windows): Omit unused local var.
17310 * menu.c (digest_single_submenu): Omit unused local var.
17311 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
17312 Omit unused local var.
17314 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
17315 Don't assume string length fits in int.
17316 (keyremap_step, read_key_sequence): Use size_t for sizes.
17317 (read_key_sequence): Don't check last_real_key_start redundantly.
17319 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
17320 instead of alloca (Bug#8344).
17322 * eval.c (Fbacktrace): Don't assume nargs fits in int.
17323 (Fbacktrace_frame): Don't assume nframes fits in int.
17325 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
17327 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
17330 * term.c (produce_glyphless_glyph): Remove unnecessary test.
17332 * cm.c (calccost): Turn while-do into do-while, for clarity.
17334 * keyboard.c (syms_of_keyboard): Use the same style as later
17335 in this function when indexing through an array. This also
17336 works around GCC bug 48267.
17338 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
17340 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
17342 * chartab.c (sub_char_table_ref_and_range): Redo for slight
17343 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
17345 * keyboard.c, keyboard.h (num_input_events): Now size_t.
17346 This avoids undefined behavior on integer overflow, and is a bit
17347 more convenient anyway since it is compared to a size_t variable.
17349 Variadic C functions now count arguments with size_t, not int.
17350 This avoids an unnecessary limitation on 64-bit machines, which
17351 caused (substring ...) to crash on large vectors (Bug#8344).
17352 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
17353 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
17354 All variadic functions and their callers changed accordingly.
17355 (struct gcpro.nvars): Now size_t, not int. All uses changed.

17574 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
17576 (command_loop_1): Use Frun_hooks. Call safe_run_hooks

17581 Fix more problems found by GCC 4.5.2's static checks.
17583 * coding.c (encode_coding_raw_text): Avoid unnecessary test
17584 the first time through the loop, since we know p0 < p1 then.
17585 This also avoids a gcc -Wstrict-overflow warning.
17587 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
17588 leading to a memory leak, possible in functions like
17589 load_charset_map_from_file that can allocate an unbounded number
17590 of objects (Bug#8318).
17592 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
17593 that could (at least in theory) be that large.
17595 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
17596 This is less likely to overflow, and avoids undefined behavior if
17597 overflow does occur. All callers changed. Use strtoul to scan

17615 * process.c (Fmake_network_process): Use socklen_t, not int,
17616 where POSIX says socklen_t is required in portable programs.
17617 This fixes a porting bug on hosts like 64-bit HP-UX, where
17618 socklen_t is wider than int (Bug#8277).
17619 (Fmake_network_process, server_accept_connection):
17620 (wait_reading_process_output, read_process_output):
17623 * process.c: Rename or move locals to avoid shadowing.

17635 Include tparam.h instead, since it declares them.
17636 * cm.h (PC): Remove extern decl; tparam.h now does this.
17637 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
17638 * terminfo.c: Include tparam.h, to check interfaces.
17639 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
17640 (tparam): Adjust signature to match interface in tparam.h;
17641 this removes some undefined behavior. Check that outstring and len
17642 are zero, which they always are with Emacs.
17643 * tparam.h (PC, BC, UP): New extern decls.
17645 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
17646 (xftfont_open): Rename locals to avoid shadowing.

17686 (alsa_choose_format): Remove unused local var.
17687 (wav_play): Initialize a variable to 0, to prevent undefined
17688 behavior (Bug#8278).

17692 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
17694 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
17695 clobbering (Bug#8298).
17696 * sysdep.c (sys_subshell): Likewise.
17697 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
17699 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
17700 This should get cleaned up, so that child_setup has the
17701 same signature on all platforms.
17703 * callproc.c (call_process_cleanup): Now static.
17704 (relocate_fd): Rename locals to avoid shadowing.
17706 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
17708 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
17709 not to be necessary, and produces flickering.
17711 2011-03-20 Glenn Morris <rgm@gnu.org>
17713 * config.in: Remove file.
17715 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

17760 Define only if needed.
17762 * unexelf.c (unexec): Name an expression,
17763 to avoid gcc -Wbad-function-cast warning.
17764 Use a different way to cause a compilation error if anyone uses
17765 n rather than nn, a way that does not involve shadowing.
17766 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
17768 * deps.mk (unexalpha.o): Remove; unused.

17825 * callint.c (quotify_arg, quotify_args): Now static.
17826 (Fcall_interactively): Rename locals to avoid shadowing.

17833 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
17834 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
17835 some of which prompt warnings from gcc -Wbad-function-cast.
17836 (Fformat_time_string, Fencode_time, Finsert_char):
17837 (Ftranslate_region_internal, Fformat):

17864 (GC_STRING_CHARS): Remove; not used.
17865 (Fmemory_limit): Cast sbrk's returned value to char *.
17867 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
17868 avoids undefined behavior in theory.
17870 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
17872 Use functions, not macros, for up- and down-casing (Bug#8254).
17873 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
17874 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
17875 to use the following functions instead of these macros.
17876 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
17877 EMACS_INT, since callers assume the returned value fits in int.
17878 (upcase1): Likewise, for UPCASE_TABLE.
17879 (uppercasep, lowercasep, upcase): New static inline functions.
17880 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

17890 (regex_compile, re_match_2_internal): Mark locals as initialized.
17891 (RETALLOC_IF): Define only if needed.
17892 (WORDCHAR_P): Likewise. This one is never needed, but is used
17893 only in a comment talking about a compiler bug, so put inside
17894 the #if 0 of that comment.
17895 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
17896 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

17922 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
17923 New macros, so that the caller can use some names other than
17924 gcpro1, gcpro2, etc.
17925 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
17927 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
17928 argument, for consistency with GCPRO2_VAR, etc: it is now the
17929 prefix of the variable, not the variable itself. All uses
17931 * dired.c (directory_files_internal, file_name_completion):
17932 Rename locals to avoid shadowing.
17934 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
17935 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
17936 dired.c's scmp function, had undefined behavior.
17937 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
17938 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
17939 * buffer.h: ... to here, because these macros use current_buffer,
17940 and the new implementation with inline functions needs to have
17941 current_buffer in scope now, rather than later when the macros
17943 (downcase, upcase1): New static inline functions.
17944 (DOWNCASE, UPCASE1): Reimplement using these functions.
17945 This avoids undefined behavior in expressions like
17946 DOWNCASE (x) == DOWNCASE (y), which previously suffered
17947 from race conditions in accessing the global variables
17948 case_temp1 and case_temp2.
17949 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
17950 * lisp.h (case_temp1, case_temp2): Remove their decls.
17951 * character.h (ASCII_CHAR_P): Move from here ...
17952 * lisp.h: ... to here, so that the inline functions mentioned
17953 above can use them.
17955 * dired.c (directory_files_internal_unwind): Now static.
17957 * fileio.c (file_name_as_directory, directory_file_name):

17960 (file_name_as_directory): Use const pointers when appropriate.
17961 (Fexpand_file_name): Likewise. In particular, newdir might
17962 point at constant storage, so make it a const pointer.
17963 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
17964 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
17966 (Fset_file_times, Finsert_file_contents, auto_save_error):

17971 to avoid shadowing.
17973 * marker.c (bytepos_to_charpos): Remove; unused.
17975 * lisp.h (verify_bytepos, count_markers): New decls,
17976 so that gcc does not warn that these functions aren't declared.
17978 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
17979 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
17980 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
17981 (copy_text): Remove unused local var.
17983 * filelock.c (within_one_second): Now static.
17984 (lock_file_1): Rename local to avoid shadowing.
17986 * buffer.c (fix_overlays_before): Mark locals as initialized.
17987 (fix_start_end_in_overlays): Likewise. This function should be
17988 simplified by using pointers-to-pointers, but that's a different
17990 (switch_to_buffer_1): Now static.
17991 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
17992 (report_overlay_modification): Rename locals to avoid shadowing.

17997 to suppress a gcc -Wclobbered warning that does not seem to be right.
17998 (MAXPATHLEN): Define only if needed.
18000 * process.c (serial_open, serial_configure): Move decls from here ...
18001 * systty.h: ... to here, so that they can be checked.
18003 * fns.c (get_random, seed_random): Move extern decls from here ...
18004 * lisp.h: ... to here, so that they can be checked.
18006 * sysdep.c (reset_io): Now static.

18166 1152921504606846976) returns the obviously-bogus value (-948597
18167 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
18168 reports time overflow. See
