16 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
18 Fix a malloc race condition involving strsignal.
19 A signal can arrive in the middle of a malloc, and Emacs's signal
20 handler can invoke strsignal, which can invoke malloc, which is
21 not portable. This race condition bug makes Emacs hang on GNU/Linux.
22 Fix it by altering the signal handler so that it does not invoke
24 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
25 * process.c (status_message): Use const pointer, in case strsignal
26 is #defined to safe_strsignal.
27 * sysdep.c (sys_siglist, init_signals): Always define and
28 initialize a substitute sys_siglist if the system does not define
29 one, even if HAVE_STRSIGNAL.
30 (safe_strsignal): Rename from strsignal. Always define,
31 using sys_siglist. Return a const pointer.
32 * syssignal.h (safe_strsignal): New decl.
33 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
35 2012-10-01 Eli Zaretskii <eliz@gnu.org>
37 * w32proc.c (timer_loop): Fix code that waits for timer
38 expiration, to avoid high CPU usage.

42 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
43 (sweep_weak_table): Remove redundant prototypes.
45 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
47 * emacs.c: Move the inclusion of TERM_HEADER after including
48 windows.h on WINDOWSNT. This avoids compilation problems with

53 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
54 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
55 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
56 as the previous version used 'void *'.
58 * ralloc.c (ROUNDUP): Fix last change.
59 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
62 * w32proc.c <disable_itimers>: New static flag.
63 (init_timers): Initialize it to zero, after creating the critical
64 sections used by the timer threads.
65 (term_timers): Set to 1 before deleting the critical sections.
66 (getitimer, setitimer): If disable_itimers is non-zero, return an
67 error indication without doing anything. Reported by Fabrice
68 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
69 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
71 [!HAVE_SETITIMER]: Behave as the previous version that didn't
74 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
75 term_ntproc after all the other bookkeeping, to get timers working
78 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
80 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
81 Suggested by Juri Linkov in
82 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
84 Prefer plain 'static' to 'static inline' (Bug#12541).
85 With static functions, modern compilers inline pretty well by
86 themselves; advice from programmers often hurts as much as it helps.
87 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
88 this change shrinks the text size of the Emacs executable by 1.1%
89 without affecting CPU significantly in my benchmark.

175 * dired.c (directory_files_internal, Ffile_attributes):

382 All uses changed to store the new value.
383 (handle_profiler_signal): Rename from sigprof_handler_1,
384 for consistency with other handlers. Do not check whether
385 cpu_log is a hash-table if garbage collecting, since it
386 doesn't matter in that case.

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

391 Prefer timer_settime if available, and prefer
392 thread cputime clocks, then process cputime clocks, then
393 monotonic clocks, to the old realtime clock. Use make_timeval
394 to round more-correctly when falling back to setitimer.
395 (Fprofiler_cpu_start): Use it.
396 (Fprofiler_cpu_stop): Prefer timer_settime if available.
397 Don't assume that passing NULL as the 2nd argument of setitimer

399 Ignore SIGPROF afterwards.
400 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
401 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
402 non-fatal signal handlers. Ignore SIGPROF on startup.
403 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
404 in profiler.c, since sysdep.c now uses it.
406 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

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

493 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
495 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
497 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
499 Prefer POSIX timers if available.
500 They avoid a race if the timer is too close to the current time.
501 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
502 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.

532 * w32proc.c (sys_signal): Handle all signals defined by the
533 MS-Windows runtime, not just SIGCHLD. Actually install the signal
534 handlers for signals supported by Windows. Don't override
535 term_ntproc as the handler for SIGABRT.
536 (sigaction): Rewrite to call sys_signal instead of duplicating its
538 (sys_kill): Improve commentary.
540 * w32.c (term_ntproc): Accept (and ignore) one argument, for
541 consistency with a signature of a signal handler. All callers
543 (init_ntproc): Accept an argument DUMPING. If dumping, don't
544 install term_ntproc as a signal handler for SIGABRT, as that
545 should be done by the dumped Emacs.
547 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
549 * w32select.c (term_w32select): Protect against repeated
550 invocation by setting clipboard_owner to NULL after calling

554 and term_ntproc to their modified signatures.
556 * character.c (char_string, string_char): Remove calls to
557 MAYBE_UNIFY_CHAR. See the discussion starting at

568 when encountering an unknown bytecode.
570 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
572 image.c, indent.c: Use bool for booleans.
573 * dispextern.h (struct image_type): Members valid_p, load, init
574 now return bool, not int. All uses changed.
575 * image.c: Omit unnecessary static decls.
576 (x_create_bitmap_mask, x_build_heuristic_mask):
577 Return void, not int, since callers don't care about the return value.

610 * chartab.c (Fset_char_table_default): Obsolete function removed.
612 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
614 Move pid_t related decls out of lisp.h.
615 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
616 (interruptible_wait_for_termination):
617 Move these decls from lisp.h to syswait.h, since they use pid_t.
618 Needed on FreeBSD; see Herbert J. Skuhra in
619 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
620 * callproc.c: Include syswait.h.

640 Use bool for boolean.
641 * gtkutil.c (xg_update_frame_menubar):
642 * xmenu.c (update_frame_menubar):
643 Return void, not int, since caller ignores return value.
644 * gtkutil.c (xg_change_toolbar_position):
647 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
649 * makefile.w32-in (BLOCKINPUT_H): Remove.

666 2012-09-23 Eli Zaretskii <eliz@gnu.org>
668 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
669 fatal_error_backtrace.
671 * w32proc.c (sys_kill): Undo last change: don't do anything when
672 invoked to deliver SIGABRT to our own process. This is now
673 handled by emacs_raise.
675 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
677 * w32term.c (w32_read_socket): Remove leftover reference to
678 interrupt_input_pending.
680 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
682 Do not use SA_NODEFER.
683 Problem reported by Dani Moncayo in
684 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
686 * sysdep.c (emacs_abort): Do not reset signal handler.
687 * emacs.c (terminate_due_to_signal): Reset signal handler here.
688 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
689 wanted even on POSIXish hosts, and it doesn't work on Windows.
691 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
693 * xterm.c (x_term_init): Call fixup_locale before and after calling
694 gtk_init (Bug#12392).
696 2012-09-23 Chong Yidong <cyd@gnu.org>
698 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
699 Vdynamic_library_alist.
701 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
702 (Fgnutls_available_p): Caller changed.
704 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
705 (Flibxml_parse_xml_region): Likewise.
707 * dispextern.h (struct image_type): Remove arg from init function.
709 * image.c (Finit_image_library, lookup_image_type)
710 (define_image_type): Remove now-unneeded second arg.
711 (init_xpm_functions, init_png_functions, init_jpeg_functions)
712 (init_tiff_functions, init_gif_functions, init_svg_functions):
713 Arglist and w32_delayed_load calling convention changed.
714 (gs_type): Remove init_gs_functions; there is no such function.
715 (valid_image_p, make_image): Fix caller to lookup_image_type.
717 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
719 Simplify and avoid signal-handling races (Bug#12471).
721 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
722 Avoid recursive loop if there's a fatal error in the function itself.
723 * atimer.c (pending_atimers):
724 * blockinput.h: Don't include "atimer.h"; no longer needed.
725 (interrupt_input_pending): Remove. All uses removed.
726 pending_signals now counts both atimers and ordinary interrupts.
727 This is less racy than having three separate pending-signal flags.
728 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
730 Rename from their upper-case counterparts BLOCK_INPUT,
731 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
732 INPUT_BLOCKED_P, and turn into functions. All uses changed.
733 This makes it easier to access volatile variables more accurately.
734 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
735 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
736 that's more reliable if the code is buggy and sets
737 interrupt_input_blocked to a negative value. All uses changed.
738 * atimer.c (deliver_alarm_signal):
739 Remove. No need to deliver this to the parent; any thread can
740 handle this signal now. All uses replaced by underlying handler.
741 * atimer.c (turn_on_atimers):
742 * dispnew.c (handle_window_change_signal):
743 * emacs.c (handle_danger_signal):
744 * keyboard.c (kbd_buffer_get_event):
745 Don't reestablish signal handler; not needed with sigaction.
746 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
748 Rework to avoid unnecessary accesses to volatile variables.
749 (UNBLOCK_INPUT_TO): Now a function.
750 (totally_unblock_input, unblock_input): New decls.
751 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
752 (init_data): Remove. Necessary stuff now done in init_signal.
753 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
754 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
755 (fatal_error_code): Remove; no longer needed.
756 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
757 it doesn't always backtrace. All uses changed. No need to reset
758 signal to default, since sigaction and/or die does that for us now.
759 Use emacs_raise (FOO), not kill (getpid (), FOO).
760 (main): Check more-accurately whether we're dumping.
761 Move fatal-error setup to sysdep.c
762 * floatfns.c: Do not include "syssignal.h"; no longer needed.
763 * gtkutil.c (xg_get_file_name, xg_get_font):
764 Remove no-longer-needed signal-mask manipulation.
765 * keyboard.c, process.c (POLL_FOR_INPUT):
766 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
767 * keyboard.c (read_avail_input): Remove.
768 All uses replaced by gobble_input.
769 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
770 (kbd_buffer_store_event_hold, gobble_input):
771 (record_asynch_buffer_change) [USABLE_SIGIO]:
772 (store_user_signal_events):
773 No need to mess with signal mask.
774 (gobble_input): If blocking input and there are terminals, simply
775 set pending_signals to 1 and return. All hooks changed to not
776 worry about whether input is blocked.
777 (process_pending_signals): Clear pending_signals before processing
778 them, in case a signal comes in while we're processing.
779 By convention callers now test pending_signals before calling us.
780 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
781 New functions, to support changes to blockinput.h.
782 (handle_input_available_signal): Now extern.
783 (reinvoke_input_signal): Remove. All uses replaced by
785 (quit_count): Now volatile, since a signal handler uses it.
786 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
787 All callers changed. Block SIGINT only if not already blocked.
788 Clear sigmask reliably, even if Fsignal returns, which it can.
789 Omit unnecessary accesses to volatile var.
790 (quit_throw_to_read_char): No need to restore sigmask.
791 * keyboard.c (gobble_input, handle_user_signal):
792 * process.c (wait_reading_process_output):
793 Call signal-handling code rather than killing ourselves.
794 * lisp.h: Include <float.h>, for...
795 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
796 (pending_signals): Now volatile.
797 (syms_of_data): Now const if IEEE floating point.
798 (handle_input_available_signal) [USABLE_SIGIO]:
799 (terminate_due_to_signal, record_child_status_change): New decls.
800 * process.c (create_process): Avoid disaster if memory is exhausted
801 while we're processing a vfork, by tightening the critical section
803 (send_process_frame, process_sent_to, handle_pipe_signal)
804 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
806 (send_process): No need for setjmp/longjmp any more, since the
807 SIGPIPE stuff is now gone. Instead, report an error if errno
809 (record_child_status_change): Now extern. PID and W are now args.
810 Return void, not bool. All callers changed.
811 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
812 Remove. All uses removed. This bug should be fixed now in a
814 (wait_for_termination_1): Use waitpid rather than sigsuspend,
815 and record the child status change directly. This avoids the
816 need to futz with the signal mask.
817 (process_fatal_action): Move here from emacs.c.
818 (emacs_sigaction_flags): New function, containing
819 much of what used to be in emacs_sigaction_init.
820 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
821 caught by emacs, to make races less likely.
822 (deliver_process_signal): Rename from handle_on_main_thread.
824 (BACKTRACE_LIMIT_MAX): Now at top level.
825 (thread_backtrace_buffer, threadback_backtrace_pointers):
827 (deliver_thread_signal, deliver_fatal_thread_signal):
828 New functions, for more-accurate delivery of thread-specific signals.
829 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
830 (deliver_arith_signal): Handle in this thread, not
831 in the main thread, since it's triggered by this thread.
832 (maybe_fatal_sig): New function.
833 (init_signals): New arg DUMPING so that we can be more accurate
834 about whether we're dumping. Caller changed.
835 Treat thread-specific signals differently from process-general signals.
836 Block all signals while handling fatal error; that's safer.
837 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
839 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
840 Ignore SIGPIPE unless batch.
841 (emacs_backtrace): Output backtrace for the appropriate thread,
842 which is not necessarily the main thread.
843 * syssignal.h: Include <stdbool.h>.
844 (emacs_raise): New macro.
845 * xterm.c (x_connection_signal): Remove; no longer needed
846 now that we use sigaction.
847 (x_connection_closed): No need to mess with sigmask now.
848 (x_initialize): No need to reset SIGPIPE handler here, since
849 init_signals does this for us now.
851 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
853 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
854 background rect may be larger (Bug#12245).
856 2012-09-23 Chong Yidong <cyd@gnu.org>
858 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
860 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
862 * .gdbinit: Just stop at fatal_error_backtrace.
863 See Stefan Monnier's request in
864 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
865 Remove no-longer-used query of system type.
867 2012-09-22 Chong Yidong <cyd@gnu.org>
869 * search.c (Freplace_match): Doc fix (Bug#12325).
871 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
873 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
874 (Fline_end_position): Doc fix.
876 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
878 2012-09-22 Chong Yidong <cyd@gnu.org>
880 * dispextern.h (struct image_type): Add new slot, storing a type
881 initialization function.
883 * image.c (define_image_type): Call the image initializer function
884 if it is defined. Arguments and return value changed.
885 (valid_image_p, make_image): Callers changed.
886 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
887 (gif_type, imagemagick_type, svg_type, gs_type):
888 Add initialization functions.
889 (Finit_image_library): Call lookup_image_type.
890 (CHECK_LIB_AVAILABLE): Macro deleted.
891 (lookup_image_type): Call define_image_type here, rather than via
892 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
893 (syms_of_image): Move define_image_type calls for xbm_type and
894 pbm_type to lookup_image_type.
896 2012-09-22 Eli Zaretskii <eliz@gnu.org>
898 * keyboard.c (timer_check_2): Move calculation of 'timers' and
899 'idle_timers' from here ...
900 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
901 lists, to avoid infloops when the timer does something stupid,
902 like reinvoke itself with the same or smaller time-out.
905 2012-09-22 Martin Rudalics <rudalics@gmx.at>
907 * window.c (Fsplit_window_internal): Handle only Qt value of
908 Vwindow_combination_limit separately.

913 2012-09-22 Eli Zaretskii <eliz@gnu.org>
915 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
916 the new overlay string. (Bug#10159)
918 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
920 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
921 or that fprintf is async-signal-safe. POSIX doesn't require
924 2012-09-22 Chong Yidong <cyd@gnu.org>
926 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
929 2012-09-22 Kenichi Handa <handa@gnu.org>
931 * composite.c (composition_reseat_it): Handle the case that a
932 grapheme cluster is not covered by a single font (Bug#12352).
934 2012-09-21 Chong Yidong <cyd@gnu.org>
936 * image.c (define_image_type): Avoid adding duplicate types to
937 image_types (Bug#12463). Suggested by Jörg Walter.
939 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
941 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
942 (print_load_command_name): Add case LC_DATA_IN_CODE.
943 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
945 2012-09-21 Glenn Morris <rgm@gnu.org>
947 * eval.c (Frun_hook_with_args_until_success)
948 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
950 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
952 * fileio.c (Ffile_selinux_context): Only call freecon when
953 lgetfilecon succeeded.
954 (Fset_file_selinux_context): Likewise. (Bug#12444)
956 2012-09-21 Eli Zaretskii <eliz@gnu.org>
958 * xdisp.c (try_window_reusing_current_matrix): Under bidi
959 reordering, locate the cursor by calling set_cursor_from_row; if
960 that fails, clear the desired glyph matrix before returning a
961 failure indication to the caller. Fixes leaving garbled display
962 when fast scrolling with a down-key. (Bug#12403)
963 (compute_stop_pos_backwards): Fix a typo that caused crashes while
964 scrolling through multibyte text.
966 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
968 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
969 calling mark_vectorlike since that's the one that marks the window.
970 (mark_discard_killed_buffers): Mark the final cdr.
971 * window.h (struct window): Move prev/next_buffers to the
973 * window.c (make_window): Initialize prev/next_buffers manually.
975 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
977 Omit unused arg EXPECTED from socket hooks.
978 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
979 * nsterm.m (ns_term_init):
980 * termhooks.h (struct terminal.read_socket_hook):
981 * w32inevt.c (w32_console_read_socket):
982 * w32term.c (w32_read_socket):
983 * xterm.c (XTread_socket):
984 Omit unused arg EXPECTED. All callers changed.
985 (store_user_signal_events): Return void, not int, since callers no
986 longer care about the return value. All uses changed.
988 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
990 * w32gui.h (XParseGeometry): Do not declare.
992 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
994 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
995 Ignore 'expected'. See Eli Zaretskii in
996 <http://bugs.gnu.org/12471#8> (last line).
998 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
999 (XParseGeometry): Now static. Substitute extremal values for
1000 values that are out of range.
1002 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
1004 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
1006 * nsfns.m (XParseGeometry): Remove.
1007 (Fx_create_frame): Call x_set_offset to correctly interpret
1008 top_pos in geometry.
1010 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
1011 (Fx_parse_geometry): If there is a space in string, call
1012 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
1014 2012-09-17 Eli Zaretskii <eliz@gnu.org>
1016 * search.c (scan_buffer): Use character positions in calls to
1017 region_cache_forward and region_cache_backward, not byte
1018 positions. (Bug#12196)
1020 * w32term.c (w32_read_socket): Set pending_signals to 1, like
1021 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
1023 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
1024 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
1025 emacs_blocked_malloc, now deleted.
1027 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
1029 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
1030 The workaround was for improving performance on Solaris 2.4, but
1031 is getting in the way now. Emacs will still work if someone is
1032 still running Solaris 2.4 in a museum somewhere; Sun dropped
1033 support for Solaris 2.4 in 2003.
1034 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
1035 * process.c (create_process) [HAVE_WORKING_VFORK]:
1036 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
1037 since Emacs no longer uses vfork on that platform.
1039 2012-09-17 Glenn Morris <rgm@gnu.org>
1041 * emacs.c: Use COPYRIGHT.
1043 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
1045 Remove configure's --without-sync-input option (Bug#12450).
1046 When auditing signal-handling in preparation for cleaning it up,
1047 I found that SYNC_INPUT has race conditions and would be a real
1048 pain to fix. Since it's an undocumented and deprecated
1049 configure-time option, now seems like a good time to remove it.
1050 Also see <http://bugs.gnu.org/11080#16>.
1051 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
1052 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
1053 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
1054 (malloc_hysteresis):
1055 (check_depth) [XMALLOC_OVERRUN_CHECK]:
1056 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
1057 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)

1059 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
1060 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
1061 [!SYSTEM_MALLOC && !SYNC_INPUT]:
1062 Remove. All uses removed.
1063 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
1064 implementation, one that depends on whether the new macro
1065 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
1067 * atimer.c (run_timers, handle_alarm_signal):
1068 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
1069 (handle_async_input, process_pending_signals)
1070 (handle_input_available_signal, init_keyboard):
1071 * nsterm.m (ns_read_socket):
1072 * process.c (wait_reading_process_output):
1073 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
1074 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
1076 * xterm.c (XTread_socket):
1078 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
1079 * eval.c (handling_signal): Remove. All uses removed.
1080 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
1081 All uses replaced with the SYNC_INPUT version.
1082 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
1084 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1087 * font.c (Ffont_shape_gstring): Remove unused local.
1089 2012-09-16 Glenn Morris <rgm@gnu.org>
1091 * Makefile.in (clean): No longer run nextstep's clean.
1093 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
1095 (ns-app): Move here from ns.mk, and simplify.
1096 (clean): Simplify nextstep entry.
1097 * ns.mk: Remove file.
1099 2012-09-17 Kenichi Handa <handa@gnu.org>
1101 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
1102 not covert the last few charactes.
1104 2012-09-16 Kenichi Handa <handa@gnu.org>
1106 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
1107 here, but just check the validity of glyphs in the glyph-string.
1109 2012-09-16 Martin Rudalics <rudalics@gmx.at>
1111 * window.c (Fwindow_parameter, Fset_window_parameter):
1112 Accept any window as argument (Bug#12452).
1114 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
1116 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
1117 to ns_term_init to avoid memory leak.
1119 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
1120 explicit retain/release.
1121 (ns_term_init): Only allow one display. Initialize outerpool and
1124 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1126 Port _setjmp fix to POSIXish hosts as well as Microsoft.
1127 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
1128 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
1129 the Microsoft problem in a different way, by altering ../nt/config.nt.
1131 2012-09-15 Eli Zaretskii <eliz@gnu.org>
1146 * w16select.c: Remove inclusion of setjmp.h, as it is now included
1147 by lisp.h. This completes removal of setjmp.h inclusion
1148 erroneously announced in the previous commit. (Bug#12446)
1150 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
1153 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
1154 not defined as a macro. The latter happens on MS-Windows.
1157 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
1159 Port better to POSIX hosts lacking _setjmp (Bug#12446).
1160 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
1161 Some instances of '#include <setjmp.h>' removed, if the
1162 only reason for the instance was because "lisp.h" was included.
1163 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
1164 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
1165 and _longjmp with the new symbols. Emacs already uses _setjmp if
1166 available, so this change affects only POSIXish hosts that have
1167 sigsetjmp but not _setjmp, such as some versions of Solaris and
1168 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
1169 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
1170 (png_load_body) [HAVE_PNG]:
1171 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
1172 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
1173 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
1174 since PNG requires jmp_buf. This is the only exception to the
1175 general rule that we now use sys_setjmp and sys_longjmp.
1176 This exception is OK since this code does not change the signal
1177 mask or longjmp out of a signal handler.
1179 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
1181 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
1182 Include "syssignal.h", for 'main_thread'.
1184 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
1186 Avoid out-of-range marker position (Bug#12426).
1187 * insdel.c (replace_range, replace_range_2):
1188 Adjust markers before overlays, as suggested by comments.
1189 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
1190 Remove redundant check before calling offset_intervals.
1192 2012-09-14 Martin Rudalics <rudalics@gmx.at>
1194 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
1195 current buffer (Bug#12387).
1197 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
1199 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
1201 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
1203 Use a more backwards-compatible timer format (Bug#12430).
1204 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
1205 vector element, not from the 4th, since PSECS is now at the end.
1206 (Fcurrent_idle_time): Doc fix.
1208 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
1210 Function to mark objects and remove killed buffers at once.
1211 * alloc.c (discard_killed_buffers): Rename to ...
1212 (mark_discard_killed buffers) ... new name. Add marking
1213 of remaining objects. Fix comment. Adjust users.
1214 (mark_object): Do not touch frame buffer lists here.
1215 * frame.c (delete_frame): Reset frame buffer lists here.
1217 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
1219 Better workaround for GNOME bug when --enable-gcc-warnings.
1220 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
1221 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
1222 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
1224 Simplify SIGIO usage (Bug#12408).
1225 The code that dealt with SIGIO was crufty and confusing, e.g., it
1226 played tricks like "#undef SIGIO" but these tricks were not used
1227 consistently. Simplify mostly by not #undeffing standard symbols,
1228 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
1229 or not as we please) rather than "defined SIGIO" (standard symbol
1230 that we probably shouldn't #undef).
1231 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
1232 Modules that need it can include it.
1233 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
1234 * dispextern.h (ignore_sigio): New decl.
1235 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
1236 unconditionally, since it's now a no-op if !USABLE_SIGIO.
1237 * emacs.c (shut_down_emacs):
1238 * keyboard.c (kbd_buffer_store_event_hold):
1239 Use ignore_sigio rather than invoking 'signal' directly.
1240 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
1242 (FIONREAD, SIGIO): Do not #undef.
1243 (tty_read_avail_input): Use #error rather than a syntax error.
1244 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
1245 for I_PIPE, used by SETUP_SLAVE_PTY.
1246 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
1247 * sysdep.c (croak): Remove; no longer needed. This bit of
1248 temporary code, with Fred N. Fish's comment that it's temporary,
1249 has been in Emacs since at least 1992!
1250 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
1251 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
1252 * syssignal.h (croak): Remove decl.
1253 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
1254 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
1255 now that we're termios-only.
1256 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
1257 * term.c (dissociate_if_controlling_tty): Use #error rather than
1260 Work around GCC and GNOME bugs when --enable-gcc-warnings.
1261 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
1262 to work around GNOME bug 683906.
1263 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
1264 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
1265 This works around GCC bug 54561.
1267 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
1269 More fixes for 'volatile' and setjmp/longjmp.
1270 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
1271 * image.c (struct png_load_context) [HAVE_PNG]: New type.
1272 (png_load_body) [HAVE_PNG]:
1273 (jpeg_load_body) [HAVE_JPEG]:
1274 New function, with most of the old parent function's body.
1275 (png_load) [HAVE_PNG]:
1276 (jpeg_load) [HAVE_JPEG]:
1277 Invoke the new function, to avoid longjmp munging our locals.
1278 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
1279 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
1280 longjmp is passed 2, as the C standard doesn't guarantee this.
1281 Instead, store the failure code into mgr->failure_code.
1283 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
1285 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
1286 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
1287 (syms_of_keyboard): Remove support for unread-command-char.
1289 2012-09-12 Eli Zaretskii <eliz@gnu.org>
1291 * w32proc.c (sys_kill): If PID is our process ID and the signal is
1292 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
1293 violation. (Bug#12426)
1295 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
1297 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
1299 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
1301 * eval.c: Add `inhibit-debugger'.
1302 (Qinhibit_debugger): New symbol.
1303 (call_debugger): Bind it instead of Qdebug_on_error.
1304 (maybe_call_debugger): Test Vinhibit_debugger.
1305 (syms_of_eval): Define inhibit-debugger.
1306 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
1307 (syms_of_xdisp): Remove inhibit-debug-on-message.
1309 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
1311 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
1312 If a nonvolatile local variable is written before a _longjmp to
1313 the frame containing the variable, and is read after the _longjmp,
1314 the value read is indeterminate. Some local variables of type
1315 'struct handler' and 'struct catchtag' are used in this way, so
1316 mark each of their slots as volatile if the slot can be set before
1317 _longjmp and read afterwards.
1318 * lisp.h (struct handler): var and chosen_clause are now volatile.
1319 (struct catchtag): val, next, and pdlcount are now volatile.
1321 * bidi.c (bidi_push_it, bidi_pop_it):
1322 * fns.c (copy_hash_table):
1323 * image.c (define_image_type):
1324 * keyboard.c (kbd_buffer_store_event_hold):
1325 * process.c (Fprocess_send_eof):
1326 * xfaces.c (x_create_gc) [HAVE_NS]:
1327 * xgselect.c (xg_select):
1328 Prefer assignment to memcpy when either will do.
1330 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
1331 Use pointer-to-a-pointer to simplify and avoid a NILP check each
1332 time an item is removed. No need to mark this function 'inline';
1333 the compiler knows better than we do.
1335 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
1337 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
1338 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
1339 to change_frame_size (Bug#12388).
1340 (windowDidResize:): Pass YES to updateFrameSize.
1342 * nsterm.h: Add delay parameter to updateFrameSize.
1344 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
1346 Discard killed buffers from deleted window and frame objects.
1347 This reduces an amount of references to killed buffers and
1348 helps GC to reclaim them faster.
1349 * alloc.c (discard_killed_buffers): New function.
1350 (mark_object): Use it for deleted windows and frames.
1351 (mark_object): If symbol's value is set up for a killed buffer
1352 or deleted frame, restore it's global binding.
1353 * data.c (swap_in_global_binding): Add GC notice.
1354 (swap_in_symval_forwarding): Use convenient set_blv_where.
1355 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
1356 * window.h: ... to here.
1358 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
1360 Convenient macro to check whether the buffer is live.
1361 * buffer.h (BUFFER_LIVE_P): New macro.
1362 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
1363 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
1365 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1367 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
1368 composition cases (Bug#12364).
1370 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
1371 overhang of succeeding glyphs overlapping box cursor.
1373 * w32term.c (x_draw_glyph_string): Likewise.
1375 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
1377 Simplify, document, and port floating-point (Bug#12381).
1378 The porting part of this patch fixes bugs on non-IEEE platforms
1379 with frexp, ldexp, logb.
1380 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
1382 * floatfns.c: Simplify discussion of functions that Emacs doesn't
1383 support, by removing commented-out code and briefly listing the
1384 C89 functions excluded. The commented-out stuff was confusing
1385 maintenance, e.g., we thought we needed cbrt but it was commented out.
1386 (logb): Remove decl; no longer needed.
1387 (isfinite): New macro, if not already supplied.
1388 (isnan): Don't replace any existing macro.
1389 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
1390 are present on all C89 platforms.
1391 (Ffrexp): Do not special-case zero, as frexp does the right thing
1393 (Flogb): Do not use logb, as it doesn't have the desired meaning
1394 on hosts that use non-base-2 floating point. Instead, stick with
1395 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
1396 frexp, to avoid getting an unspecified result.
1398 * xdisp.c (Qinhibit_debug_on_message): Now static.
1400 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
1402 * nsterm.m (ns_update_begin): Set clip path to whole view by using
1403 NSBezierPath (Bug#12131).
1405 2012-09-10 Chong Yidong <cyd@gnu.org>
1407 * fns.c (Fdelq, Fdelete): Doc fix.
1409 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
1411 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
1412 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
1414 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
1416 * lisp.h (make_lisp_ptr): New macro to replace XSET.
1417 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
1420 2012-09-09 Eli Zaretskii <eliz@gnu.org>
1422 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
1423 left fringe if the window has a left margin. This avoids leaving
1424 traces of the cursor because its leftmost pixel is not drawn over.
1426 * dispnew.c (update_window_line): When the left margin area of a
1427 screen line is updated, set the redraw_fringe_bitmaps_p flag of
1428 that screen line. (Bug#12277)
1430 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
1432 Assume C89 or later for math functions (Bug#12381).
1433 This simplifies the code, and makes it a bit smaller and faster,
1434 and (most important) makes it easier to clean up signal handling
1435 since we can stop worring about floating-point exceptions in
1436 library code. That was a problem before C89, but the problem
1437 went away many years ago on all practical Emacs targets.
1438 * data.c, image.c, lread.c, print.c:
1439 Don't include <math.h>; no longer needed.
1440 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
1441 might be autoconfigured, as that never happens.
1443 * doprnt.c (DBL_MAX_10_EXP):
1444 * print.c (DBL_DIG):
1445 Remove. C89 or later always defines these.
1446 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
1447 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
1448 (arith_error, domain_error, domain_error2):
1449 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
1450 no longer needed -- we simply return what C returns. All uses removed.
1451 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
1453 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
1454 Remove. All uses expanded, as these macros are no longer used
1455 more than once and are now more trouble than they're worth.
1456 (Ftan): Use tan, not sin / cos.
1457 (Flogb): Assume C89 frexp.
1458 (fmod_float): Assume C89 fmod.
1459 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
1460 (init_floatfns): Remove. All uses removed.
1462 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1464 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
1465 compositeToPoint for OSX < 10.6 (Bug#12390).
1467 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
1469 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
1470 This produces more-accurate results.
1472 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1474 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
1475 changes (Bug#12088).
1477 2012-09-08 Chong Yidong <cyd@gnu.org>
1479 * syntax.c (Fstring_to_syntax): Doc fix.
1481 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
1483 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
1484 in the internal border.
1485 (x_set_window_size): Remove static variables and their usage.
1486 (ns_redraw_scroll_bars): Fix NSTRACE arg.
1487 (ns_after_update_window_line, ns_draw_fringe_bitmap):
1488 Remove fringe/internal border adjustment (Bug#11052).
1489 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
1490 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
1491 (ns_fix_rect_ibw): Remove.
1492 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
1493 (ns_dumpglyphs_box_or_relief): Ditto.
1494 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
1496 (ns_dumpglyphs_image): Ditto.
1497 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
1499 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
1500 their usage. Add fringe_extended_p and its use as in other terms.
1501 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
1502 scroll bar was removed.
1503 (updateFrameSize): New function.
1504 (windowDidResize): Move code to updateFrameSize and call it.
1506 * nsterm.h (EmacsView): Add updateFrameSize.
1508 2012-09-07 Chong Yidong <cyd@gnu.org>
1510 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
1512 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
1514 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1516 More signal-handler cleanup (Bug#12327).
1517 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
1518 Problem introduced when merging patches. Noted by Eli Zaretskii in
1519 <http://bugs.gnu.org/12327#67>.
1520 * floatfns.c: Comment fix.
1521 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
1522 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
1523 and anyway the declaration is harmless even if SIGDANGER is not defined.
1524 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
1525 defined BROKEN_FIONREAD). systty.h formerly did this, but other
1526 source files not surprisingly expected syssignal.h to define, or
1527 not define, SIGIO, and it's cleaner to do it that way, for consistency.
1528 Include <sys/ioctl.h>, for FIONREAD.
1529 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
1530 This eliminates a problem whereby other files mysteriously had
1531 to include "syssignal.h" before including "systty.h" if they
1532 wanted to use "#ifdef SIGIO".
1534 2012-09-07 Eli Zaretskii <eliz@gnu.org>
1536 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
1538 * w32.c (sigemptyset): Empty the set.
1539 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
1541 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
1543 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
1545 * alloc.c (mark_buffer): Revert unsafe marking optimization.
1546 (mark_object): Likewise for frame objects.
1548 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
1550 * syssignal.h (handle_on_main_thread): Always declare,
1551 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
1552 This ports to platforms without HAVE_PTHREAD.
1554 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1556 Signal-handler cleanup (Bug#12327).
1557 Emacs's signal handlers were written in the old 4.2BSD style with
1558 sigblock and sigmask and so forth, and this led to some
1559 inefficiencies and confusion. Rewrite these to use
1560 pthread_sigmask etc. without copying signal sets around. Also,
1561 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
1562 'signal', and instead use functions that do not attempt to take
1563 over the system name space. This patch causes Emacs's text
1564 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
1565 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
1566 Do not include <signal.h> or "syssignal.h", as these
1567 modules do not use signals.
1568 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
1569 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
1570 Do not include <signal.h>, as "syssignal.h" does that for us now.
1571 * atimer.c (sigmask_atimers): New function.
1572 (block_atimers, unblock_atimers): New functions,
1573 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
1575 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
1576 no longer needed here.
1577 * emacs.c (main): Inspect existing signal handler with sigaction,
1578 so that there's no need to block and unblock SIGHUP.
1579 * sysdep.c (struct save_signal): New member 'action', replacing
1580 old member 'handler'.
1581 (save_signal_handlers, restore_signal_handlers):
1582 Use sigaction instead of 'signal' to save and restore.
1583 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
1584 New function. All users of 'signal' modified to use set_sighandler
1585 if they're writeonly, and to use sys_signal if they're read+write.
1586 (emacs_sigaction_init, forwarded_signal): New functions.
1587 (sys_signal): Remove. All uses replaced by calls to sigaction
1588 and emacs_sigaction_init, or by direct calls to 'signal'.
1589 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
1590 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
1591 all uses replaced by pthread_sigmask etc. calls.
1592 * syssignal.h: Include <signal.h>.
1593 (emacs_sigaction_init, forwarded_signal): New decls.
1594 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
1595 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
1596 (sigmask, sys_sigmask): Remove; no longer needed.
1597 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
1598 (sigblock, sigunblock, sigfree):
1599 (sigsetmask) [!defined sigsetmask]:
1600 Remove. All uses replaced by pthread_sigmask.
1601 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
1602 no longer need to be replaced, and its typical old uses
1603 are now done via emacs_sigaction_init and sigaction.
1604 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
1605 (sys_sigdel): Remove; unused.
1606 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
1608 2012-09-06 Eli Zaretskii <eliz@gnu.org>
1610 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
1611 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
1613 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1615 Explicitly mark buffer_defaults and buffer_local_symbols.
1616 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
1617 mark_local_symbols here.
1618 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
1619 since special buffers aren't marked here any more.
1620 (allocate_buffer): Chain new buffer with all_buffers here...
1621 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
1623 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
1624 (syms_of_buffer): Remove staticpro of the above.
1625 (init_buffer_once): Set names for buffer_defaults and
1626 buffer_local_symbols.
1628 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
1630 Use bool for booleans in font-related modules.
1631 * font.c (font_intern_prop, font_style_to_value)
1632 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
1633 (generate_otf_features, font_check_otf_features, font_check_otf)
1634 (font_match_p, font_list_entities, font_at):
1635 * fontset.c (fontset_id_valid_p, reorder_font_vector
1636 (fontset_find_font, Fset_fontset_font)
1637 (face_suitable_for_char_p) [0]:
1638 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
1639 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
1640 (m17n_flt_initialized, ftfont_shape_by_flt):
1641 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
1642 * nsfont.m (nsfont_draw):
1643 * w32font.c (w32font_draw):
1644 * w32term.c (x_draw_glyphless_glyph_string_foreground):
1645 Use bool for booleans.
1646 * font.h: Adjust to above API changes.
1647 (struct font, struct font_driver, struct font_driver_list):
1648 Use bool for booleans.
1649 (struct font): Remove useless member encoding_type.
1651 * fontset.c, xftfont.c: Omit unnecessary static decls.
1653 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
1655 * alloc.c (mark_object): Revert window marking code
1656 since it's unsafe for the Fset_window_configuration.
1658 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1660 Fix race conditions with signal handlers and errno (Bug#12327).
1661 Be more systematic about preserving errno whenever a signal
1662 handler returns, even if it's not in the main thread. Do this by
1663 renaming signal handlers to distinguish between signal delivery
1664 and signal handling. All uses changed.
1665 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
1666 * data.c (deliver_arith_signal): Rename from arith_error.
1667 * dispnew.c (deliver_window_change_signal): Rename from
1668 window_change_signal.
1669 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
1670 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
1671 * keyboard.c (deliver_input_available_signal): Rename from
1672 input_available_signal.
1673 (deliver_user_signal): Rename from handle_user_signal.
1674 (deliver_interrupt_signal): Rename from interrupt_signal.
1675 * process.c (deliver_pipe_signal): Rename from send_process_trap.
1676 (deliver_child_signal): Rename from sigchld_handler.
1677 * atimer.c (handle_alarm_signal):
1678 * data.c (handle_arith_signal):
1679 * dispnew.c (handle_window_change_signal):
1680 * emacs.c (handle_fatal_signal, handle_danger_signal):
1681 * keyboard.c (handle_input_available_signal):
1682 * keyboard.c (handle_user_signal, handle_interrupt_signal):
1683 * process.c (handle_pipe_signal, handle_child_signal):
1684 New functions, with the actual signal-handling code taken from the
1685 original respective signal handlers, sans the sporadic attempts to
1686 preserve errno, since that's now done by handle_on_main_thread.
1687 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
1688 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
1689 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1691 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1692 Move initialization of main_thread to sysdep.c's init_signals.
1693 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
1694 our usage, and simplifies the mainline code.
1695 (record_child_status_change): New static function, as a helper
1696 for handle_child_signal, and with most of the old child handler's
1698 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
1699 (handle_child_signal): Use the above.
1700 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
1701 Moved here from emacs.c.
1702 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
1703 code moved here from emacs.c's main function.
1704 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
1705 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
1706 This lets callers save and restore errno properly.
1708 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1710 Remove redundant or unused things here and there.
1711 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
1712 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
1713 * editfns.c (Fcompare_buffer_substrings): Likewise.
1714 * frame.h (struct terminal, struct font_driver_list):
1715 Remove redundant declarations.
1716 * window.h (Qleft, Qright): Likewise.
1718 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1720 Do not mark objects from deleted buffers, windows and frames.
1721 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
1722 (mark_object): Likewise for windows and frames.
1724 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
1726 * alloc.c (valid_lisp_object_p): Treat killed buffers,
1727 buffer_defaults and buffer_local_symbols as valid objects.
1728 Return special value to denote them.
1730 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
1732 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
1733 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
1734 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
1735 (file_name_absolute_p, Fsubstitute_in_file_name):
1736 (check_executable, check_writable, Ffile_accessible_directory_p)
1737 (Fset_file_selinux_context, Fdefault_file_modes)
1738 (Finsert_file_contents, choose_write_coding_system)
1739 (Fwrite_region, build_annotations, a_write, e_write)
1741 * filelock.c (boot_time_initialized, get_boot_time)
1742 (get_boot_time_1, lock_file_1, within_one_second):
1743 * floatfns.c (in_float):
1744 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
1745 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
1746 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
1747 * lisp.h (struct Lisp_Hash_Table.cmpfn):
1748 * window.c (compare_window_configurations):
1749 Use bool for booleans.
1750 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
1751 (Fdefault_file_modes): Now mode_t, not int, for modes.
1752 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
1753 (internal_delete_file): Now returns void, not a (boolean) int,
1754 since nobody was looking at the return value.
1755 * lisp.h, window.h: Adjust to above API changes.
1757 * xdisp.c (set_message): Simplify and reindent last change.
1759 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
1761 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
1763 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
1765 * eval.c (call_debugger): Make the function non-static so that we
1766 can call it from set_message.
1768 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
1769 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
1771 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1773 Give more-useful info on a fatal error (Bug#12328).
1774 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
1775 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
1776 of doing the work ourselves.
1777 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
1778 do most of the work.
1779 (fatal_error_backtrace): New function, taken from the guts
1780 of the old fatal_error_signal, but with a new option to output
1782 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
1783 info about the signal than just its number.
1784 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
1785 * sysdep.c: Include <execinfo.h>
1786 (emacs_backtrace): New function, taken partly from the previous
1787 code of the 'die' function.
1788 (emacs_abort): Call fatal_error_backtrace rather than abort.
1790 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
1792 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
1793 eager (load-time) macro-expansion.
1794 * lisp.mk (lisp): Add macroexp.
1796 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
1798 Simplify redefinition of 'abort' (Bug#12316).
1799 Do not try to redefine the 'abort' function. Instead, redo
1800 the code so that it calls 'emacs_abort' rather than 'abort'.
1801 This removes the need for the NO_ABORT configure-time macro
1802 and makes it easier to change the abort code to do a backtrace.
1803 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
1804 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
1805 Remove; sysdep.c's emacs_abort now takes its place.
1806 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
1807 'abort' changed to use 'emacs_abort'.
1808 * msdos.c (dos_abort) [defined abort]: Remove; not used.
1809 (abort) [!defined abort]: Rename to ...
1810 (emacs_abort): ... new name.
1811 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
1812 the place of the old 'abort' in emacs.c.
1813 * w32.c, w32fns.c (abort): Do not #undef.
1814 * w32.c (emacs_abort): Rename from w32_abort.
1816 2012-09-04 Eli Zaretskii <eliz@gnu.org>
1818 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
1819 offsets[j].dv, since the y axis of the screen coordinates points
1820 down, while the y axis of the font definition coordinates points
1821 up. This fixes display of Arabic diacritics such as KASRA and
1822 KASRATAN. (Bug#11860)
1824 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>

1827 * alloc.c (test_setjmp, mark_stack):
1828 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
1829 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
1830 (png_load, my_error_exit, jpeg_load):
1831 * process.c (send_process_trap, send_process):
1832 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
1833 The underscored versions are up to 30x faster on some hosts.
1834 Formerly, the code used setjmp+longjmp sometimes and
1835 _setjmp+_longjmp at other times, with no particular reason to
1836 prefer setjmp+longjmp.
1838 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
1840 Fix minor problem found by static checking.

1870 won't change, instead of the address of 'initialize', whose
1871 signature just changed from int to bool.
1872 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
1873 * msdos.c (fatal_error_in_progress): ... from here.
1874 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
1876 (redisplay_internal, unwind_redisplay): Simply clear
1877 REDISPLAYING_P when unwinding, instead of saving its previous,
1878 always-false value and then restoring it.
1880 Clean up some extern decls.
1881 Mostly, this hoists extern decls out of .c files and into .h files.
1882 That way, we're more likely to catch errors if the interfaces change.
1883 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
1884 declare xg_mark_data.
1885 * dispextern.h (x_frame_parm_handlers):

1906 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
1907 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
1909 * xfaces.c: Remove unnecessary static decls.
1910 * xterm.c (updating_frame): Remove decl of nonexistent object.
1912 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
1913 when building globals.h, as the objects that are not built on
1914 this host are not needed to compile C files on this host.

1968 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
1969 more than one grapheme cluster passed to the shaper: compute the
1970 offset adjustment values separately for each cluster. (Bug#11860)
1972 * image.c: Restore mistakenly removed inclusion of w32.h. Without
1973 it, GCC doesn't see prototypes of w32_delayed_load, and complains
1974 about implicit conversions from integer to pointer.
1976 2012-09-01 Daniel Colascione <dancol@dancol.org>
1978 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
1979 system used too early.

2032 window system declarations.
2034 * frame.h: Move common functions here: set_frame_menubar,
2035 x_set_window_size, x_sync, x_get_focus_frame,
2036 x_set_mouse_position, x_set_mouse_pixel_position,
2037 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

2064 * lisp.h (mark_ttys): Remove prototype.
2065 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call

2123 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
2124 Add window_closed and button_values. Add void as return value for
2125 add(Button|String|Split). addButton takes int instead of Lisp_Object.
2126 Add process_dialog as new member.

2260 (code_convert_string, code_convert_string_norecord)
2261 (Fset_coding_system_priority):
2262 * fileio.c (Finsert_file_contents):
2263 Use bool for booleans.
2264 * coding.h, lisp.h: Reflect above API changes.
2265 * coding.c: Remove unnecessary static function decls.
2266 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
2267 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
2268 not a boolean 'int', since callers never look at the return value.
2269 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
2270 * coding.h (decoding_buffer_size, encoding_buffer_size)
2271 (emacs_mule_string_char): Remove unused extern decls.
2272 (struct iso_2022_spec, struct coding_system):
2273 Use 'unsigned int : 1' for boolean fields, since there's more than one.
2274 (struct emacs_mule_spec): Remove unused field 'full_support'.
2275 All initializations removed.
2276 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
2278 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
2280 Fix spare memory change (Bug#12286).
2281 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
2282 (valid_lisp_object_p): Likewise.
2284 2012-08-27 Martin Rudalics <rudalics@gmx.at>
2286 * window.c (Fset_window_configuration): Record any window's old
2287 buffer if it's replaced (see Bug#8789). If the new current
2288 buffer doesn't appear in the selected window, go to its old
2291 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
2293 Special MEM_TYPE_SPARE to denote reserved memory.
2294 * alloc.c (enum mem_type): New memory type.
2295 (refill_memory_reserve): Use new type for spare memory.
2296 This prevents live_cons_p and live_string_p from incorrect
2297 detection of uninitialized objects from spare memory as live.
2299 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
2302 * Makefile.in (.PHONY): versioclean -> versionclean.
2304 Remove unused external symbols.
2305 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
2306 * window.c (Qwindow_valid_p, decode_valid_window):
2307 Now static, not extern.
2308 * data.c (Qinterval): Remove; unused.
2309 (syms_of_data): Do not define 'interval'.
2310 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
2311 * window.h (decode_valid_window):
2314 * character.c, charset.c, chartab.c: Use bool for booleans.
2315 * character.c (lisp_string_width, string_count_byte8)
2316 (string_escape_byte8):
2317 * charset.c (charset_map_loaded, load_charset_map, read_hex):
2318 (load_charset_map_from_file, map_charset_chars)
2319 (Fdefine_charset_internal, define_charset_internal)
2320 (Fdeclare_equiv_charset, find_charsets_in_text)
2321 (Ffind_charset_region, char_charset, Fiso_charset):
2322 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
2323 (sub_char_table_set, sub_char_table_set_range)
2324 (char_table_set_range, optimize_sub_char_table)
2325 (map_sub_char_table):
2326 Use bool for boolean.
2327 * character.c (str_to_unibyte): Omit last boolean argument; it was
2328 always 0. All callers changed.
2329 * character.h, charset.h: Adjust to match previous changes.
2330 * character.h (char_printable_p): Remove decl of nonexistent function.
2331 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
2332 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
2333 are all boolean, so make them single-bit bitfields.
2335 * lisp.h (ASET): Remove attempt to detect side effects.
2336 It was meant to be temporary and it often doesn't work,
2337 because when IDX has side effects the behavior of IDX==IDX
2338 is undefined. See Stefan Monnier in
2339 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
2341 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
2343 * lisp.h (functionp): New function (extracted from Ffunctionp).
2344 (FUNCTIONP): Use it.
2345 * eval.c (Ffunctionp): Use it.
2347 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
2349 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
2350 as that's faster and simpler than static storage. Don't bother
2351 with the g_main_context_query overhead if g_main_context_pending
2352 says no events are pending.
2353 (gfds, gfds_size): Remove these static vars.
2354 (xgselect_initialize): Remove; no longer needed.
2355 All uses and decls removed.
2357 * emacs.c (fatal_error_signal_hook): Remove.
2358 All uses removed. This leftover from old code was always 0.
2360 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
2361 * casefiddle.c (casify_object, casify_region):
2362 * casetab.c (set_case_table):
2363 * category.c, category.h (word_boundary_p):
2364 * category.h (CHAR_HAS_CATEGORY):
2365 Use bool for booleans, instead of int.
2367 2012-08-25 Eli Zaretskii <eliz@gnu.org>
2369 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
2371 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
2373 On assertion failure, print backtrace if available.
2374 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
2375 (die) [ENABLE_CHECKING]: Print a backtrace if available.
2376 * Makefile.in (LIB_EXECINFO): New macro.
2379 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
2380 * bytecode.c (exec_byte_code):
2381 * callint.c (check_mark, Fcall_interactively):
2382 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
2383 (getenv_internal, sync_process_alive, call_process_exited):
2384 * lisp.h (USE_SAFE_ALLOCA):
2385 Use bool for booleans, instead of int.
2386 * lisp.h, process.h: Adjust prototypes to match above changes.
2387 * callint.c (Fcall_interactively): Don't assume the mark's
2388 offset fits in 'int'.
2390 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
2392 * buffer.c, buffer.h: Use bool for boolean.
2393 * buffer.c (reset_buffer_local_variables)
2394 (buffer_lisp_local_variables, Fset_buffer_modified_p)
2395 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
2396 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
2397 (overlay_touches_p, overlay_strings, Foverlay_put)
2398 (report_overlay_modification, call_overlay_mod_hooks):
2399 (mmap_enlarge, mmap_set_vars):
2400 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
2401 Use bool for booleans, instead of int.
2402 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
2403 since the 1-or-0 return value is always ignored anyway.
2404 (mmap_initialized_p):
2405 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
2406 * buffer.h, lisp.h: Adjust prototypes to match above changes.
2408 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
2410 * bidi.c: Use bool for boolean.
2411 This is a bit more readable, and makes the text segment of bidi.o
2412 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
2413 Presumably it's faster too.
2414 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
2416 (bidi_cache_find_level_change, bidi_cache_iterator_state)
2417 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
2418 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
2419 (bidi_explicit_dir_char, bidi_level_of_next_char)
2420 (bidi_find_other_level_edge, bidi_move_to_visually_next):
2421 Use bool for booleans, instead of int.
2422 * dispextern.h (bidi_init_it, bidi_paragraph_init)
2423 (bidi_unshelve_cache): Adjust decls to match code.
2425 2012-08-23 Martin Rudalics <rudalics@gmx.at>
2427 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
2430 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
2432 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
2433 * atimer.h: Include <stdbool.h>.
2435 2012-08-22 Dan Nicolaescu <dann@gnu.org>
2437 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
2438 compile time tests instead of run time tests on systems that do
2440 (FRAME_MAC_P): Remove leftover from deleted code.
2441 * frame.c (syms_of_frame): Remove leftover from deleted code.
2443 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
2445 * nsterm.m (insertText:): Don't clear modifiers if code is space.
2447 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
2449 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
2450 Otherwise, the compiler complains about (A?B:C) where B is void
2451 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
2452 (fontset_add): Return void, for FONTSET_ADD.
2454 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2456 * alloc.c: Use bool for booleans.
2457 (gc_in_progress, abort_on_gc)
2458 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
2459 (dont_register_blocks) [GC_MALLOC_CHECK]:
2460 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
2461 (check_string_bytes, make_specified_string, memory_full)
2462 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
2463 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
2464 (mark_stack, valid_pointer_p, make_pure_string)
2465 (Fgarbage_collect, survives_gc_p, gc_sweep):
2466 Use bool for booleans, instead of int.
2467 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
2468 Remove unused local.
2469 * alloc.c (PURE_POINTER_P):
2470 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
2471 * editfns.c (Fformat):
2472 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
2474 * fns.c (sweep_weak_table):
2475 * lisp.h (suppress_checking, push_message, survives_gc_p)
2476 (make_pure_string, gc_in_progress, abort_on_gc):
2477 * lread.c (readchar, read1):
2478 * print.c (Fprin1_to_string):
2479 * xdisp.c (push_message):
2480 Use bool for booleans affected directly or indirectly by
2483 Make recently-introduced setters macros.
2484 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
2485 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
2486 (set_fontset_default, set_fontset_fallback): Rename from their
2487 upper-case counterparts, and make them functions rather than macros.
2488 This is more consistent with the other recently-introduced setters.
2489 These don't need to be inline, since they're local.
2491 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
2493 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
2494 the loop (Bug#12247).
2496 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2498 * lisp.h (vcopy): Use memcpy rather than our own loop.
2499 This fixes a performance regression introduced by the recent
2500 addition of vcopy. This means 'vcopy' will need to be modified
2501 for a copying collector, but that's OK. Also, tighten the
2502 checking in the assertion.
2504 2012-08-21 Eli Zaretskii <eliz@gnu.org>
2506 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
2507 components for RTL text (Bug#11860). Adjust X-OFFSET of each
2508 non-base glyph for the width of the base character, according to
2509 what x_draw_composite_glyph_string_foreground expects.
2510 Generate WADJUST value according to composition_gstring_width's
2511 expectations, to produce correct width of the composed character.
2512 Reverse the sign of the DU offset produced by ScriptPlace.
2514 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
2516 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
2518 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2520 Avoid direct writes to contents member of struct Lisp_Vector.
2521 * lisp.h (vcopy): New function to copy data into vector.
2522 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
2523 * fns.c (Ffillarray): Use ASET.
2524 * keyboard.c (timer_check_2): Use AREF and ASET.
2525 (append_tool_bar_item, Frecent_keys): Use vcopy.
2526 * lread.c (read_vector): Use ASET.
2527 * msdos.c (Frecent_doskeys): Use vcopy.
2528 * xface.c (Finternal_copy_lisp_face): Use vcopy.
2529 (Finternal_merge_in_global_face): Use ASET and vcopy.
2530 * xfont.c (xfont_list_pattern): Likewise.
2532 2012-08-21 Martin Rudalics <rudalics@gmx.at>
2534 * window.c (Fwindow_point): For the selected window always return
2535 the position of its buffer's point.
2536 (Fset_window_point): For the selected window always go in its
2537 buffer to the specified position.
2539 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
2541 Setter macros for fontsets.
2542 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
2543 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
2544 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
2547 2012-08-20 Glenn Morris <rgm@gnu.org>
2549 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
2550 Don't assume that `ln -f' works.
2552 2012-08-20 Eli Zaretskii <eliz@gnu.org>
2554 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
2555 and later about non-assignments with no effect. See discussion at
2556 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
2559 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2561 Inline setter functions for Lisp_Objects slots of struct specbinding.
2562 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
2565 2012-08-20 Martin Rudalics <rudalics@gmx.at>
2567 * window.c (select_window): Always make selected window's buffer
2570 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2572 Use AREF and ASET for docstrings of category tables.
2573 * category.h (CATEGORY_DOCSTRING): Use AREF.
2574 (SET_CATEGORY_DOCSTRING): Use ASET.
2575 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
2577 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2579 Inline setter functions for hash table members.
2580 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
2581 (set_hash_hash, set_hash_index): Rename with _slot suffix.
2582 (set_hash_key_and_value, set_hash_index, set_hash_next)
2583 (set_hash_hash): New functions.
2584 * charset.c, fns.c: Adjust users.
2586 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
2588 Inline getter and setter functions for per-buffer values.
2589 * buffer.h (per_buffer_default, set_per_buffer_default)
2590 (per_buffer_value, set_per_buffer_value): New functions.
2591 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
2592 * buffer.c, data.c: Adjust users.
2594 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
2596 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
2598 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
2600 Rely on <config.h> + <unistd.h> to declare 'environ',
2601 as gnulib does this if the system doesn't.
2602 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
2603 Remove declaration. MS-Windows declares it on stdlib.h which is
2604 included by conf_post.h.
2605 * emacs.c (environ) [DOUG_LEA_MALLOC]:
2606 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
2607 * vm-limit.c: Include <unistd.h>, for 'environ'.
2609 * unexaix.c, unexcoff.c: Include "mem-limits.h".
2610 (start_of_data): Remove decl; mem-limits.h provides it.
2612 * xdisp.c (handle_invisible_prop): Make it a bit faster
2613 and avoid a gcc -Wmaybe-uninitialized diagnostic.
2615 2012-08-19 Chong Yidong <cyd@gnu.org>
2617 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
2620 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
2622 * .gdbinit: Use call instead of set when calling a function in the
2625 * data.c (set_internal): Don't use set_blv_found.
2626 (Fkill_local_variable): Likewise.
2628 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
2630 * nsfont.m (ns_ascii_average_width): Ensure the string
2631 ascii_printable is initialized with a null-terminated character
2632 array. Otherwise, it can contain undesired extra characters.
2634 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
2636 port new setting code to Sun C 5.8 2005/10/13
2637 * chartab.c, lisp.h (char_table_set, char_table_set_range):
2638 Return void, not Lisp_Object. Otherwise, the compiler
2639 complains about (A?B:C) where B is void and C is Lisp_Object
2640 when compiling CHAR_TABLE_SET, due to the recent change to
2641 the API of sub_char_table_set_contents.
2643 2012-08-18 Chong Yidong <cyd@gnu.org>
2645 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
2646 for the string case (Bug#3874).
2648 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
2650 * buffer.h (BSET): Remove (Bug#12215).
2651 Replace all uses with calls to new setter functions.

2678 (bset_word_wrap, bset_zv_marker):
2679 * category.c (bset_category_table):
2680 * syntax.c (bset_syntax_table):
2681 New setter functions.
2683 * process.h (PSET): Remove (Bug#12215).
2684 Replace all uses with calls to new setter functions.
2685 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
2686 (PROCESS_INLINE): New macro.
2687 (pset_childp): New setter function.
2688 (pset_gnutls_cred_type) [HAVE_GNUTLS]: New setter function.
2689 * process.c (PROCESS_INLINE):

3583 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
3584 checking subscripts; problem introduced with the recent
3585 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
3586 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
3587 since it's used in non-static inline functions now.
3589 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

3642 This how ASET and AREF are supposed to work, and makes
3643 it easier to think about future improvements. See
3644 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.

4022 * w32inevt.c: Include w32inevt.h.
4023 (w32_read_console_input): New inline function, calls either
4024 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
4025 w32_console_unicode_input.
4026 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
4027 (w32_kbd_patch_key, key_event): Use the codepage returned by
4028 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
4029 (key_event): use uChar.UnicodeChar only if
4030 w32_console_unicode_input is non-zero.
4032 * w32console.c: Include w32heap.h.

4057 * alloc.c (listn): Fix the order the arguments are consed onto the
4060 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
4061 enumeration constants, as PURE and HEAP are too general, and clash
4062 with other headers and sources, such as gmalloc.c and the
4063 MS-Windows system headers. All users changed.
4065 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
4067 Revert last save_excursion_save and save_excursion_restore changes.
4068 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

4078 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
4080 Improve GDB symbol export (Bug#12036).
4081 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
4082 arms of an 'if', not using conditional expressions; otherwise GDB
4083 complains about the types in the unevaluated arm when the argument
4084 is an integer literal.
4085 (xgetint): Simplify expression.
4086 * alloc.c (gdb_make_enums_visible): New constant. This ports to
4087 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
4088 Zaretskii in <http://bugs.gnu.org/12036#13>.
4089 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
4090 needed now that we have gdb_make_enums_visible.
4091 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
4092 (enum enum_USE_LSB_TAG):
4093 New enum types, packaging up enums that need to be exported to GDB.
4095 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

4112 * xfns.c (syms_of_xfns): Likewise.
4114 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
4116 Fast save_excursion_save and save_excursion_restore.
4117 * lisp.h (struct Lisp_Excursion): New data type.
4118 (PVEC_EXCURSION): New pseudovector type.
4119 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
4120 to deal with it. Adjust comments.

4133 Fix export of symbols to GDB (Bug#12036).
4134 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
4135 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
4136 emacs.c, as this is a more-suitable home. Had this been done earlier
4137 the fix for 12036 would have avoided some of the problems noted in
4138 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
4139 would have been more obvious.
4140 * emacs.c: Do not include <verify.h>; no longer needed.
4141 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
4142 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
4143 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
4144 Remove; now done in lisp.h.
4145 * lisp.h (PUBLISH_TO_GDB): New macro.
4146 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
4147 (DATA_SEG_BITS): Use it.
4148 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
4149 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
4150 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
4151 not be usable in #if. This simplifies things.
4153 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
4155 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
4157 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
4159 Simplify export of symbols to GDB (Bug#12036).
4160 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
4161 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
4162 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
4163 Adjust to changes in lisp.h and emacs.c, by using
4164 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
4165 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
4166 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
4167 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
4168 instead of gdb_valbits.
4169 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
4170 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
4171 instead of gdb_array_mark_flag.
4172 (xboolvector): Get size from $->size, not $->header.size.
4173 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
4174 (xreload, hook-run, hookpost-run): Remove.
4175 * emacs.c: Include <verify.h>.
4176 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
4177 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
4179 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
4180 (gdb_USE_LSB_TAG): New enum constants.
4181 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
4182 Also define these as enum constants, so they're visible to GDB.
4183 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
4184 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
4185 as constants, so they're visible to GDB.
4186 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
4187 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
4188 Now enum constants, not macros, so they're visible to GDB.
4189 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
4190 more convenient now. All uses changed.
4191 (VALMASK) [USE_LSB_TAG]: Also define in this case.
4192 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
4194 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

4201 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
4202 add argument, tune behavior, and adjust all callers.
4204 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
4206 Use typedef for EMACS_INT, EMACS_UINT.
4207 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
4208 than macros. This simplifies debugging in the usual case, since
4209 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
4210 and it allows expressions involving EMACS_INT casts.
4211 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
4213 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
4215 * nsterm.m (ns_read_socket): Return early if there is a modal

4221 that FOCUS-FRAME can be omitted.
4223 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
4225 Adjust buffer text indirection counters at the end of Fkill_buffer.
4226 * buffer.c (Fkill_buffer): Adjust indirection counters when the
4227 buffer is definitely dead. This should really fix an issue reported
4228 by Christoph Scholtes again. (Bug#12007).
4229 (init_buffer_once): Initialize indirection counters of
4230 buffer_defaults and buffer_local_symbols (for sanity and safety).
4232 2012-07-24 Eli Zaretskii <eliz@gnu.org>
4234 * xdisp.c (init_iterator): Don't compute dimensions of truncation
4235 and continuation glyphs on tooltip frames, leave them at zero.

4238 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
4240 Simplify copy_overlay.
4241 * buffer.c (copy_overlay): Simplify. Use build_marker.

4263 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
4265 Swap buffer text indirection counters in Fbuffer_swap_text.
4266 * buffer.c (Fbuffer_swap_text): Swap indirections too.
4267 This avoids crash reported by Christoph Scholtes at
4268 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
4270 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
4272 * nsmenu.m (Popdown_data): New struct.
4273 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
4275 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
4276 (initWithContentRect): Make imgView and contentView non-static
4277 and autorelease them. Also autorelease img and matrix (Bug#12005).
4278 (dealloc): Remove (Bug#12005).
4280 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
4282 Adjust consing_since_gc when objects are explicitly freed.
4283 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
4284 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.

4291 (live_buffer, set_marker_internal): New function.
4292 (Fset_marker, set_marker_restricted): Use set_marker_internal.

4295 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
4297 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
4298 as it's limited by the amount of memory, not by INT_MAX.
4300 2012-07-21 Eli Zaretskii <eliz@gnu.org>
4302 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
4303 in special-event-map. See the discussion at
4304 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
4307 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning
4308 info.dwItemData. Fixes crashes on 64-bit Windows.

4362 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
4363 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
4364 Adjust users accordingly.
4365 * font.h (font_open_by_name): Adjust prototype.

4383 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
4384 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
4385 'for_each_per_buffer_object_at'.
4386 All uses changed. It's better to use upper-case for macros that
4387 cannot be implemented as functions, to give the reader a clue
4388 that they're special.
4390 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
4392 * alloc.c (Fgarbage_collect): Tweak docstring.

4433 * intervals.c (merge_interval_right, merge_interval_left):
4434 Do not zero out this interval if it is absorbed by its children,
4435 as this interval's total length doesn't change in that case. See

4438 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
4440 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
4441 when invoking (make-bool-vector N t) and N is a positive
4442 multiple of 8 -- the last 8 bits were mistakenly cleared.
4444 Remove some struct layout assumptions in bool vectors.
4445 * alloc.c (bool_header_size): New constant.
4446 (header_size, word_size): Move earlier, as they're now used earlier.
4447 Use 'word_size' in a few more places, where it's appropriate.

4449 padding before the data member of a bool vector.
4450 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather

4954 2012-07-11 Glenn Morris <rgm@gnu.org>
4956 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
4957 since nothing has defined it on these platforms.
4959 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/gnu-linux.h:
4960 * s/irix6-5.h: Move SIGNALS_VIA_CHARACTERS to configure.

4971 2012-07-11 John Wiegley <johnw@newartisans.com>
4973 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
4974 function attribute, so we only use it if it exists in the
4977 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
4979 Avoid call to strlen in fast_c_string_match_ignore_case.

5026 * s/aix4-2.h (unix): Remove; no longer needed.
5028 EMACS_TIME simplification (Bug#11875).
5029 This replaces macros (which typically do not work in GDB)
5030 with functions, typedefs and enums, making the code easier to debug.
5031 The functional style also makes code easier to read and maintain.
5032 * systime.h: Include <sys/time.h> on all hosts, not just if
5033 WINDOWSNT, since 'struct timeval' is needed in general.
5034 (EMACS_TIME): Now a typedef, not a macro.
5035 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
5037 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

5041 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
5042 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
5043 which are not functions. All uses rewritten to use:
5044 (make_emacs_time): New function.
5045 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
5046 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
5047 not functions. All uses rewritten to use the following, respectively:
5048 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
5049 (add_emacs_time, sub_emacs_time): New functions.
5050 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
5051 * fileio.c (Fcopy_file):
5052 * xterm.c (XTflash): Get the current time closer to when it's used.
5053 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

5061 * gtkutil.c (get_utf8_string):
5063 * nsmenu.m (ns_update_menubar):
5064 * regex.c (regerror):
5065 Prefer memcpy to strncpy and strncat when either will do.

5067 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
5068 (menu_separator_name_p):
5069 * nsmenu.m (ns_update_menubar):
5070 Prefer memcmp to strncmp when either will do.
5071 * nsterm.m: Include <ftoastr.h>.
5073 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
5074 Prefer snprintf to strncpy.
5075 * nsterm.m (ns_term_init):
5076 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
5077 * nsterm.m (ns_term_init):
5078 Avoid the need for strncpy, by using build_string or
5079 make_unibyte_string directly. Use dtoastr, not snprintf.
5080 * process.c (Fmake_network_process): Diagnose service names that
5081 are too long, rather than silently truncating them or creating
5082 non-null-terminated names.
5083 (Fnetwork_interface_info): Likewise, for interface names.
5084 * sysdep.c (system_process_attributes) [GNU_LINUX]:
5085 Prefer sprintf to strncat.
5086 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
5087 Prefer vsnprintf to vsprintf + strncpy.
5089 2012-07-10 Glenn Morris <rgm@gnu.org>
5091 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
5092 Clarify fallback case.
5094 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
5096 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
5097 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
5098 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
5099 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
5100 where argument type is known to be a Lisp_Cons.
5102 2012-07-10 Tom Tromey <tromey@redhat.com>
5104 * bytecode.c (BYTE_CODE_THREADED): New macro.
5105 (BYTE_CODES): New macro. Replaces all old byte-code defines.

5112 Optimize pure C strings initialization.
5113 * lisp.h (make_pure_string): Fix prototype.
5114 (build_pure_c_string): New function, defined as static inline. This
5115 provides a better opportunity to optimize away calls to strlen when
5116 the function is called with compile-time constant argument.
5117 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
5118 argument, adjust users accordingly. Use build_pure_c_string where
5120 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
5121 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
5122 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
5124 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
5126 Avoid calls to strlen in miscellaneous functions.
5127 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
5128 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
5129 * lread.c (openp): Likewise.
5131 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
5133 Avoid calls to strlen in path processing functions.
5134 * fileio.c (file_name_as_directory): Add comment. Change to add
5135 srclen argument and return the length of result. Adjust users
5137 (directory_file_name): Fix comment. Change to add srclen argument,
5138 swap 1st and 2nd arguments to obey the common convention.
5139 Adjust users accordingly.
5140 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
5142 2012-07-10 Glenn Morris <rgm@gnu.org>
5144 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

5147 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
5148 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
5149 * s/gnu.h (DATA_START): Move definitions to configure.
5151 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
5152 We include usg5-4-common.h, which defines them both.
5154 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
5155 O_RDONLY already includes it).
5157 Stop ns builds setting the EMACSLOADPATH environment variable.
5158 * nsterm.m (ns_load_path): Rename from ns_init_paths.
5159 Now it does not set EMACSLOADPATH, just returns the load-path string.
5160 * nsterm.h: Update accordingly.
5161 * lread.c [HAVE_NS]: Include nsterm.h.
5162 (init_lread) [HAVE_NS]: Use ns_load_path.
5163 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
5165 2012-07-09 Glenn Morris <rgm@gnu.org>
5167 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
5168 since the included bsd-common.h does so.
5170 Stop ns builds setting the EMACSPATH environment variable.
5171 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
5172 (ns_init_paths): Do not set EMACSPATH.
5173 * nsterm.h (ns_exec_path): Add it.
5174 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
5177 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
5179 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
5181 * process.c (wait_reading_process_output): 'waitchannels' was unset
5182 when read_kbd || !NILP (wait_for_cell); fix this.
5184 Add GCC-style 'const' attribute to functions that can use it.
5185 * character.h (char_resolve_modifier_mask):
5186 * keyboard.h (make_ctrl_char):
5187 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
5188 (init_character_once, next_almost_prime, init_fns, init_image)
5189 (flush_pending_output, init_sound):
5190 * mem-limits.h (start_of_data):
5191 * menu.h (finish_menu_items):
5192 Add ATTRIBUTE_CONST.

5194 Declare the dummy function with ATTRIBUTE_CONST.
5195 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
5196 Add decls with ATTRIBUTE_CONST.
5198 Minor improvements to make_formatted_string.
5199 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
5200 where int is good enough, as vsprintf returns an int.
5201 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
5203 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
5205 Use make_formatted_string to avoid double length calculation.
5206 * lisp.h (make_formatted_string): New prototype.
5207 * alloc.c (make_formatted_string): New function.
5208 * buffer.c (Fgenerate_new_buffer_name): Use it.
5209 * dbus.c (syms_of_dbusbind): Likewise.
5210 * editfns.c (Fcurrent_time_zone): Likewise.
5211 * filelock.c (get_boot_time): Likewise.
5212 * frame.c (make_terminal_frame, set_term_frame_name)
5213 (x_report_frame_params): Likewise.
5214 * image.c (gs_load): Likewise.
5215 * minibuf.c (get_minibuffer): Likewise.
5216 * msdos.c (dos_set_window_size): Likewise.
5217 * process.c (make_process): Likewise.

5230 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
5232 Move marker debugging code under MARKER_DEBUG.
5233 * marker.c (MARKER_DEBUG): Move marker debugging code under
5234 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
5235 for bootstrap with --enable-checking (~3x slowdown reported
5236 by Juanma Barranquero <lekktu@gmail.com>).
5237 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
5239 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
5241 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
5242 See <http://bugs.gnu.org/11825#29>.
5244 2012-07-08 Eli Zaretskii <eliz@gnu.org>
5246 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
5247 has no font, use the frame's font. (Bug#11813)
5248 (display_line): Add commentary about displaying truncation glyphs
5250 (produce_special_glyphs): Move here from term.c.
5252 * term.c (produce_special_glyphs): Move to xdisp.c.
5254 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
5257 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
5259 * xdisp.c (display_line): Avoid warning about implicit declaration
5262 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
5264 * lisp.h: Remove empty conditional.
5266 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
5268 * lread.c (load_path_check): Now static.
5270 Fix some minor --with-ns problems found by static checking.
5271 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
5272 (x_set_font) [!HAVE_X_WINDOWS]:
5273 * image.c (xpm_load_image) [HAVE_NS]:
5274 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
5275 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
5276 Remove unused local.
5277 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
5278 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
5279 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
5280 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
5281 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
5282 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
5283 Fix pointer signedness problem.
5284 * xfaces.c (FRAME_X_FONT_TABLE):
5285 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
5287 2012-07-07 Glenn Morris <rgm@gnu.org>
5289 * lread.c (load_path_check): New function, split from init_lread.
5290 (init_lread): Reorganize. Motivation:
5291 If EMACSLOADPATH is set, check/warn about that rather than the
5292 defaults, which we are not going to use. Hence we can remove
5293 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
5294 Don't warn if site-lisp directories are missing.
5295 If not installed, start from a blank load-path, since
5296 PATH_LOADSEARCH refers to the eventual installation directories.
5298 2012-07-07 Eli Zaretskii <eliz@gnu.org>
5300 Support truncation and continuation glyphs on GUI frames, when
5301 fringes are disabled. (Bug#11832)
5302 * xdisp.c (init_iterator): Get dimensions of truncation and
5303 continuation glyphs even if on GUI frames.
5304 Adjust it->last_visible_x on GUI frames when the left or right fringes,
5305 or both, are absent.
5306 (start_display, move_it_in_display_line_to): Handle the case of a
5307 GUI frame without a fringe to display continuation or truncation
5309 (insert_left_trunc_glyphs): Support GUI frames: make sure
5310 truncation glyphs overwrite enough glyphs from the current line to
5311 have sufficient space in pixels.
5312 (display_line): Support truncation and continuation glyphs on GUI
5313 frames. If some spare pixels are left on the line after inserting
5314 the truncation glyphs, fill that space with a stretch glyph of a
5315 suitably computed width.
5317 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
5318 produce_glyphs, to support GUI sessions.
5320 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
5322 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
5324 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
5326 Do not require float-time's arg to fit in time_t (Bug#11825).
5327 This works better on hosts where time_t is unsigned, and where
5328 float-time is applied to the (negative) difference between two times.
5329 * editfns.c (decode_time_components): Last arg is now double *,
5330 not int *, and means to store all the result as a double, without
5331 worrying about whether the seconds part fits in time_t.
5332 All callers changed.
5333 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
5334 All callers changed.
5335 (Ffloat_time): Do not fail merely because the specified time falls
5336 outside of time_t range.
5338 2012-07-07 Glenn Morris <rgm@gnu.org>
5340 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
5341 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
5342 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
5344 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
5346 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
5347 Update dependencies.

5355 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
5356 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.

5365 * w32fns.c (Fx_change_window_property): Doc fix.
5367 * w32fns.c (Fx_window_property): Accept the same arguments as the
5368 X Windows version. Doc fix.
5369 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
5371 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
5372 Eli Zaretskii <eliz@gnu.org>
5374 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.

5380 * process.c: Avoid unnecessary calls to gettime.
5381 (wait_reading_process_output): Don't get the time of day
5382 when gobbling data immediately and not waiting, as there's no need
5383 for it in that case. This removes a FIXME.
5385 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
5387 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
5388 is defined (Bug#11768).

5392 Fix marker debugging code.
5393 * marker.c (byte_char_debug_check): Do not perform the check
5394 if buffer is not multibyte.
5395 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
5396 Call byte_char_debug_check with correct arguments.
5398 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5400 Compile marker debugging code only if ENABLE_CHECKING is defined.
5401 * marker.c (byte_char_debug_check, count_markers):
5402 Use only if ENABLE_CHECKING is defined.
5403 (byte_debug_flag): Remove.
5404 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
5405 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
5407 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
5409 Avoid code repetition in marker-related functions.
5410 * marker.c (attach_marker): New function.

5413 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
5414 Consistently rename charno to charpos.
5415 (marker_position): Add eassert.
5416 (marker_byte_position): Convert to eassert.

5428 * lisp.h (build_marker): New prototype.
5429 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
5430 * composite.c (autocmp_chars): Likewise.
5431 * editfns.c (buildmark): Remove.
5432 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
5433 (save_restriction_save): Use build_marker.
5434 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
5435 * window.c (save_window_save): Likewise.
5437 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

5442 (delete_all_overlays, Fdelete_overlay): Use it.
5443 * minibuf.c (get_minibuffer): Fix comment.
5445 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
5447 Port to OpenBSD 5.1 amd64.
5448 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
5449 This is needed for OpenBSD, and should be harmless on all BSD systems.
5450 Also, include <sys/sysctl.h>, as it should be available on all
5451 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
5452 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
5453 use p_pid member, not kp_proc.pid.
5455 2012-07-06 Glenn Morris <rgm@gnu.org>
5457 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
5459 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
5461 More xmalloc and related cleanup.
5462 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

5470 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
5472 Omit needless casts involving void * pointers and allocation.
5473 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
5474 as the former is more robust if P's type is changed.
5475 Prefer xzalloc to xmalloc + memset 0.
5476 Simplify malloc-or-realloc to realloc.
5477 Don't worry about xmalloc returning a null pointer.
5478 Prefer xstrdup to xmalloc + strcpy.
5479 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
5481 * keyboard.c (apply_modifiers_uncached): Prefer local array to
5482 alloca of a constant.
5484 2012-07-05 Eli Zaretskii <eliz@gnu.org>
5486 * xdisp.c (display_line): Fix horizontal pixel coordinates when
5487 hscroll is larger than the line width. Fixes long and futile
5488 looping inside extend_face_to_end_of_line (on a TTY) producing
5489 glyphs that are not needed and thrown away.
5491 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
5493 * marker.c (set_marker_restricted_both): Simplify by using
5496 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

5505 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
5506 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
5507 followed by gtk_box_set_homogeneous (Bug#11768).
5508 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
5509 (update_theme_scrollbar_width, xg_create_scroll_bar):
5510 Use gtk_scrollbar_new (Bug#11768).
5511 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
5512 (is_box_type): New function (Bug#11768).

5519 * xdisp.c (window_hscroll_limited): New function.
5520 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
5521 coordinates when window's hscroll is set to insanely large
5524 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
5526 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

5587 * fileio.c (time_error_value): Check the right error number.
5588 Problem reported by Troels Nielsen in
5589 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

5593 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
5594 This should be fixed in a better way; see Eli Zaretskii in
5595 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
5596 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
5598 * fileio.c (time_error_value): Rename from special_mtime.
5599 The old name's problems were noted by Eli Zaretskii in
5600 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
5602 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
5603 This variable's comment says Emacs needs at least one GDB-visible
5604 symbol of type enum pvec_type, to work around GDB problems.
5605 The symbol's value doesn't matter.
5607 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
5608 that causes compilation to fail on pre-C99 compilers.
5610 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
5612 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

5623 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
5624 * lisp.h (enum pvec_type): Use fewer bits.
5625 (PSEUDOVECTOR_SIZE_BITS): New constant.
5626 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
5627 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
5628 change in pvec_type.

5635 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
5636 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
5637 (sweep_vectors): Use it. Use local var `total_bytes' instead of
5638 abusing vector->header.next.nbytes.
5639 (live_vector_p): Use PVEC_TYPE.
5640 (mark_object): Adapt code to extract pvectype. Use switch.
5642 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5644 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
5645 Tighten new eassert a bit.
5647 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
5649 Fix compilation with --enable-gcc-warnings and -O1
5651 * doprnt.c (doprnt): Change type of tem to int, initialize
5652 to avoid compiler warning. Add eassert.
5653 * search.c (simple_search): Initialize match_byte to avoid
5654 compiler warning. Add eassert.
5656 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5658 Avoid weird behavior with large horizontal scrolls.
5659 Without this change, for example, large hscroll values would
5660 mess up Emacs's display on Fedora 15 x86, presumably due to
5661 overflows in int calculations in the display code.
5662 Also, if buffers had long lines, Emacs would freeze.
5663 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
5664 (set_window_hscroll): New function, containing the old guts of
5665 Fset_window_hscroll. Return the clipped value.
5666 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
5667 This avoids the need to check against PTRDIFF_MAX.
5669 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
5671 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

5675 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
5677 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
5678 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
5679 since GCC 4.4.6 issues a bogus warning for them.
5681 Fix bugs in file timestamp newness comparisons.
5682 * fileio.c (Ffile_newer_than_file_p):
5683 * lread.c (Fload): Use full timestamp resolution of files,
5684 not just the 1-second resolution, so that files that are only
5685 slightly newer still count as newer.
5686 * fileio.c (Ffile_newer_than_file_p): Don't assume file
5687 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
5689 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
5691 * fileio.c: Improve handling of file time marker. (Bug#11852)

5698 * fileio.c (Finsert_file_contents): Properly handle st_mtime
5699 marker for non-existing file. (Bug#11852)
5701 2012-07-03 Glenn Morris <rgm@gnu.org>
5703 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
5704 and did not make it into globals.h).
5706 2012-07-03 Tom Tromey <tromey@redhat.com>

5746 * lisp.h (Frandom): Make it visible to C.
5747 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
5748 buffer for invisible buffers. (Bug#1229)

5752 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
5753 values which aren't power of 2.
5754 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
5755 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
5758 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
5760 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

5766 * alloc.c (allocate_vector_block): Remove redundant
5767 calls to mallopt if DOUG_LEA_MALLOC is defined.
5768 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
5769 avoid calls to mallopt if zero_vector is returned.
5771 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5773 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
5774 is enabled, avoid dereferencing NULL current_sblock if
5777 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
5779 Cleanup basic buffer management.
5780 * buffer.h (struct buffer): Change layout to use generic vector
5781 marking code. Fix some comments. Change type of 'clip_changed'
5782 to bitfield. Remove unused #ifndef old.
5783 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.

5789 * alloc.c (allocate_buffer): Adjust to match new layout of
5790 struct buffer. Fix comment.

5793 Lisp area of struct buffer.
5794 (mark_object): Use it. Adjust marking of misc objects
5795 and related comments.
5797 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
5799 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
5800 wrapper that is not needed because the wrapped code is a no-op (zero
5801 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
5802 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
5804 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
5806 * alloc.c (mark_buffer): Simplify. Remove prototype.
5807 (mark_object): Add comment. Reorganize marking of vector-like
5808 objects. Use CHECK_LIVE for all vector-like objects except buffers
5809 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
5810 Avoid redundant calls to mark_vectorlike for bool vectors.
5812 2012-06-30 Glenn Morris <rgm@gnu.org>
5814 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
5816 * epaths.in (PATH_SITELOADSEARCH): New.
5817 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
5818 This is rather than relying on --enable-locallisppath elements
5819 having "site-lisp" in their names. (Bug#10208#25, 11658)
5821 2012-06-30 Eli Zaretskii <eliz@gnu.org>
5823 * w32proc.c (sys_select): Accept and ignore one more argument.
5825 * w32.c (emacs_gnutls_pull): Call select with one more argument.
5827 * sysselect.h [DOS_NT]: Don't include sys/select.h.
5828 (pselect) [!MS_DOS]: Redirect to sys_select.
5830 * sysdep.c: Don't include dos.h and dosfns.h.
5832 * process.c (sys_select):
5833 * msdos.c (sys_select): Accept one more argument and ignore it.
5835 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
5836 adapt data types and code to that.
5839 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
5840 which clashes with the gnulib function of the same name.
5842 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
5844 * font.c (font_style_to_value, font_style_symbolic)

5848 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
5850 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
5853 2012-06-29 Eli Zaretskii <eliz@gnu.org>
5855 * xdisp.c (try_window_id): Undo last change.
5857 * w32.c (getwd): Adjust commentary about startup_dir.
5858 (init_environment): Always call sys_access, even in non-MSVC
5859 builds. Don't chdir to the directory of the Emacs executable.
5860 This undoes code from 1997 which was justified by the need to
5861 "avoid conflicts when removing and renaming directories". But its
5862 downside was that every relative file name was being interpreted
5863 relative to the directory of the Emacs executable, which can never
5864 be TRT. In particular, it broke sys_access when called with
5865 relative file names.
5866 (sys_access): Map GetLastError to errno.
5868 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
5870 * window.h (struct window): Change type of 'fringes_outside_margins'

5880 Add QUIT to make the loop interruptible.
5882 2012-06-29 Glenn Morris <rgm@gnu.org>

5910 * window.h (struct window): Change type of 'hscroll',
5911 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,

5914 * xdisp.c (try_cursor_movement): Replace type check with eassert.
5915 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
5916 from EMACS_INT to ptrdiff_t.

6050 * alloc.c: Remove build_string.
6051 * lisp.h: Define build_string as static inline. This provides
6052 a better opportunity to optimize away calls to strlen when the
6053 function is called with compile-time constant argument.

6055 * w32proc.c (sys_spawnve): Likewise.

6058 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
6060 Use sprintf return value instead of invoking strlen on result.
6061 In the old days this wasn't portable, since some sprintf
6062 implementations returned char *. But they died out years ago and
6063 Emacs already assumes sprintf returns int.
6064 Similarly for float_to_string.
6065 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

6071 * xdisp.c (message_dolog):
6072 * xfns.c (syms_of_xfns):
6073 Use sprintf or float_to_string result to avoid need to call strlen.
6074 * data.c (Fnumber_to_string):
6075 Use make_unibyte_string, since the string must be ASCII.
6076 * lisp.h, print.c (float_to_string): Now returns int length.
6077 * term.c (produce_glyphless_glyph):
6078 Use sprintf result rather than recomputing it.
6080 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
6081 * Makefile.in (ALL_CFLAGS):
6082 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

6088 strcasecmp if available.

6111 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
6113 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

6116 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
6118 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
6119 instead of truncating it to 63 (admittedly a generous limit).
6121 * process.c: Fix spelling and caps in comments.
6123 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>

6179 * keyboard.c (kbd_buffer_get_event):
6180 * process.c (Faccept_process_output):
6181 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
6182 This improves on the previous patch, which introduced a bug
6183 when time_t is unsigned and as wide as intmax_t.
6184 See <http://bugs.gnu.org/9000#51>.

6203 Privately reported by Herbert J. Skuhra.
6204 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
6206 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
6207 not make_lisp_timeval, when the argument is of type EMACS_TIME.

6249 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
6251 Support higher-resolution time stamps (Bug#9000).
6252 The time stamps are only nanosecond-resolution at the C level,
6253 since that's the best that any real-world system supports now.
6254 But they are picosecond-resolution at the Lisp level, as that's
6255 easy, and leaves room for future OS improvements.
6257 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
6260 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
6261 Don't get current time unless it's needed.
6263 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
6264 now provides it if it's absent.
6265 (start_atimer): Port to higher-res time stamps.
6266 Check for time stamp overflow. Don't get current time more
6267 often than is needed.
6269 * buffer.h (struct buffer): Buffer modtime now has high resolution.
6270 Include systime.h, not time.h.
6271 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
6273 * dired.c: Include stat-time.h.
6274 (Ffile-attributes): File times now have higher resolution.
6276 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
6277 (struct image): Timestamp now has higher resolution.
6279 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
6280 has at least microseconds now. All uses removed.
6281 (update_frame, update_single_window, update_window, update_frame_1)
6282 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
6283 (duration_to_sec_usec): Remove; no longer needed.
6285 * editfns.c (time_overflow): Now extern.
6286 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
6287 (float-time, Fformat_time_string, Fcurrent_time_string)

6290 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
6291 (decode_time_components, lisp_seconds_argument): New functions.
6292 (make_time): Now static.
6293 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
6294 Report an error if the time is invalid, rather than having the caller
6297 * fileio.c: Include <stat-time.h>
6298 (Fcopy_file): Copy higher-resolution time stamps.
6299 Prefer to set the time stamp via a file descriptor if that works.
6300 (Fset_file_times, Finsert_file_contents, Fwrite_region)
6301 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
6302 (Fvisited_file_modtime, Fset_visited_file_modtime):
6303 Support higher-resolution time stamps.
6305 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
6307 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
6309 * image.c (prepare_image_for_display, clear_image_cache)
6310 (lookup_image): Port to higer-resolution time stamps.
6312 * keyboard.c (start_polling, bind_polling_period):
6313 Check for time stamp overflow.
6314 (read_char, kbd_buffer_get_event, timer_start_idle)
6315 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
6316 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
6317 Port to higher-resolution time stamps. Do not assume time_t is signed.
6318 (decode_timer): New function. Timers are now vectors of length 9,
6319 not 8, to accommodate the picosecond component.
6320 (timer_check_2): Use it.
6322 * nsterm.m (select_timeout, timeval_subtract): Remove.
6323 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
6324 as they're a bit more accurate and handle overflow better.
6325 (ns_select): Change prototype to be compatible with pselect.
6326 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
6327 * nsterm.h (ns_select): Adjust prototype.
6329 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
6330 us-resolution time stamps.
6331 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
6333 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
6335 * lisp.h (time_overflow): New decl.
6336 (wait_reading_process_output): First arg is now intmax_t, not int,
6337 to accommodate larger waits.
6339 * process.h (struct Lisp_Process.read_output_delay):
6340 Now counts nanoseconds, not microseconds.
6341 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
6343 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
6344 (wait_reading_process_output):
6345 Port to ns-resolution time stamps.
6346 (Faccept_process_output, wait_reading_process_output):
6347 Check for time stamp overflow. Do not assume time_t is signed.
6348 (select_wrapper): Remove; we now use pselect.
6349 (Fprocess_attributes): Now generates ns-resolution time stamps.
6351 * sysdep.c: Include utimens.h. Don't include utime.h
6352 or worry about struct utimbuf; gnulib does that for us now.
6353 (gettimeofday): Remove; gnulib provides a substitute.
6354 (make_timeval): New function.
6355 (set_file_times): Now sets ns-resolution time stamps.
6356 New arg FD; all uses changed.
6357 (time_from_jiffies, ltime_from_jiffies, get_up_time)
6358 (system_process_attributes):
6359 Now returns ns-resolution time stamp. All uses changed.
6360 Check for time stamp overflow.
6362 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
6363 provides a substitute now.
6365 * systime.h: Include timespec.h rather than sys/time.h and time.h,
6366 since it guarantees struct timespec.
6367 (EMACS_TIME): Now struct timespec, so that we can support
6368 ns-resolution time stamps.
6369 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
6370 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
6371 (EMACS_USECS): Remove.
6372 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
6373 so multiply the arg by 1000 before storing it.
6374 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
6376 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

6381 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
6382 (set_file_times, make_time, lisp_time_argument): Adjust signature.
6383 (make_timeval, make_lisp_time, decode_time_components): New decls.
6384 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
6385 that it mishandled time_t overflow. You can't compare by subtracting!
6386 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
6387 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
6389 * term.c: Include <sys/time.h>.
6390 (timeval_to_Time): New function, for proper overflow wraparound.
6391 (term_mouse_position, term_mouse_click): Use it.
6393 * undo.c (record_first_change): Support higher-resolution time stamps
6395 (Fprimitive_undo): Use them when restoring time stamps.
6397 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
6398 (w32_get_internal_run_time):
6399 Port to higher-resolution Emacs time stamps.
6400 (ltime): Now accepts single 64-bit integer, as that's more convenient
6403 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
6405 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
6406 for compatibility with pselect. Support ns-resolution time stamps.
6408 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
6410 * xselect.c (wait_for_property_change, x_get_foreign_selection):
6411 Check for time stamp overflow, and support ns-resolution time stamps.
6413 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
6414 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
6415 (timeval_subtract): Remove; no longer needed.
6416 (XTflash, XTring_bell, x_wait_for_event):
6417 Port to ns-resolution time stamps. Don't assume time_t is signed.

6423 2012-06-22 Eli Zaretskii <eliz@gnu.org>
6425 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
6426 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
6427 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
6428 staticidx goes up to 1597 out of 1600 = 0x640.)
6430 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
6432 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
6433 Otherwise, the umask might be mistakenly 0 while handling input signals.
6435 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
6437 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

6443 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
6444 access to `contents' member of Lisp_Vector objects with AREF and ASET
6447 2012-06-19 Chong Yidong <cyd@gnu.org>
6449 * frame.c (delete_frame): When selecting a frame on a different
6450 text terminal, do not alter the terminal's top-frame.

6453 frame's selected window and its terminal's top-frame.
6454 (unwind_format_mode_line): Restore them.
6455 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
6457 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
6458 since tty frames can be explicitly named.
6459 (prepare_menu_bars): Likewise.
6461 * term.c (Ftty_top_frame): New function.
6463 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
6465 Port byte-code-meter to modern targets.
6466 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
6467 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
6468 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
6469 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
6470 (METER_1, METER_2): Simplify.
6472 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

6476 2012-06-18 Martin Rudalics <rudalics@gmx.at>
6478 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
6479 gets killed during executing of this function (Bug#11665).
6480 Try to always return Qt when the buffer has been actually killed.
6481 (Vkill_buffer_query_functions): In doc-string say that functions
6482 run by this hook should not change the current buffer.
6484 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
6486 Fix recently-introduced process.c problems found by static checking.
6487 * process.c (write_queue_push, write_queue_pop, send_process):

6504 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
6506 * lisp.h (eassert): Assume C89 or later.
6507 This removes the need for CHECK.
6508 (CHECK): Remove. Its comments about always evaluating its
6509 argument were confusing, as 'eassert' typically does not evaluate
6512 * coding.c (produce_chars): Use ptrdiff_t, not int.
6514 * xterm.c (x_draw_underwave): Check for integer overflow.
6515 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

6810 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
6811 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
6813 2012-06-08 Eli Zaretskii <eliz@gnu.org>
6815 * alloc.c (allocate_vectorlike): Fix last change.

6821 adjust comment accordingly.
6822 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
6823 to denote vector blocks. Adjust users (live_vector_p,
6824 mark_maybe_pointer, valid_lisp_object_p) accordingly.
6825 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
6826 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
6827 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
6828 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),
6829 (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.

6846 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
6848 * doprnt.c (doprnt): Truncate multibyte char correctly.
6849 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
6850 would mishandle a string argument "Xc" if X was a multibyte
6851 character of length 2: it would truncate after X's first byte
6852 rather than including all of X.
6854 2012-06-06 Chong Yidong <cyd@gnu.org>
6856 * buffer.c (word_wrap): Doc fix.
6858 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

6903 * minibuf.c (Fassoc_string): Remove duplicate declaration.
6905 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
6906 Convert pctcpu and pctmem to Lisp float properly.
6907 Let the compiler fold better, as 100.0/0x8000 is exact.
6909 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
6911 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
6914 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
6916 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
6918 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
6920 For a 'struct window', replace some Lisp_Object fields to
6921 bitfields where appropriate, remove unused fields.
6922 * window.h (struct window): Remove unused 'last_mark_x' and
6923 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
6924 change it's type from Lisp_Object to bitfield.
6925 Change type of 'force_start', 'optional_new_start',
6926 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
6927 fields from Lisp_Object to bitfield. Adjust users accordingly.
6929 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6931 Pacify gcc -Wdouble-precision when using Xaw.
6932 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
6933 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
6934 Use 'float' consistently, rather than 'float' in most places
6935 and 'double' in a couple of places.
6937 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6939 * xdisp.c (handle_stop): Detect whether we have overlay strings
6940 loaded by testing it->current.overlay_string_index to be
6941 non-negative, instead of checking whether n_overlay_strings is
6942 positive. (Bug#11587)
6944 2012-05-31 Chong Yidong <cyd@gnu.org>
6946 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
6948 * doc.c (Fsubstitute_command_keys): Doc fix.
6950 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6952 * search.c (search_buffer): Remove calls to
6953 r_alloc_inhibit_buffer_relocation, as it is now called by
6954 maybe_unify_char, which was the cause of relocation of buffer text
6957 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6959 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
6960 for the duration of call to load_charset, to avoid problems with
6961 callers of maybe_unify_char that access buffer text through C
6964 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
6965 decrement the inhibition flag, instead of just setting or
6968 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6970 Remove obsolete '#define static' cruft.
6971 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
6972 This #undef was "temporary" in 2000; it is no longer needed
6973 now that '#define static' has gone away.
6974 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
6975 (gray_bitmap_bits): Remove; no longer needed.
6976 All uses replaced with definiens.
6977 * xterm.c: Include "bitmaps/gray.xbm".
6979 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
6981 Clean up __executable_start, monstartup when --enable-profiling.
6982 The following changes affect the code only when profiling.
6983 * dispnew.c (__executable_start): Rename from safe_bcopy.
6984 Define only on platforms that need it.
6985 * emacs.c: Include <sys/gmon.h> when profiling.
6986 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
6987 (__executable_start): Remove decl, since lisp.h does it now.
6988 (safe_bcopy): Remove decl; no longer has that name.
6989 (main): Coalesce #if into single bit of code, for simplicity.
6990 Cast pointers to uintptr_t, since standard libraries want integers

7015 * lread.c (read1): Tiny simplification.
7017 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
7019 Do not create empty overlays with the evaporate property (Bug#9642).
7020 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
7021 Bug#9642, but explicitly check that the buffer the overlay would
7022 be moved to is live and rearrange lines to make sure that errors
7023 will not put the overlay in an inconsistent state.
7024 (Fdelete_overlay): Cosmetics.
7026 2012-05-28 Eli Zaretskii <eliz@gnu.org>
7028 * w32term.c (my_bring_window_to_top): New function.
7029 (x_raise_frame): Use handle returned by DeferWindowPos, which
7030 could be different from the original one.

7034 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
7035 by calling BringWindowToTop.
7037 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
7038 (WM_EMACS_END): Increase by one.
7040 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
7042 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
7043 This avoids undefined behavior that might cause the eassert
7044 to not catch an out-of-range value.
7046 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
7048 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

7058 when referring to sectname field in printf format.
7060 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
7062 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
7063 Only r_alloc_inhibit_buffer_relocation needed to be added;
7064 the others were already declared.
7066 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
7067 before checking whether it's out of range. Put the check inside
7069 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
7071 2012-05-27 Ken Brown <kbrown@cornell.edu>
7073 * callproc.c (Fcall_process): Restore a line that was accidentally
7074 commented out in the 2011-02-13 change (bug#11547).

7078 * lisp.h [REL_ALLOC]: Add prototypes for external functions
7079 defined on ralloc.c.
7081 * buffer.c [REL_ALLOC]: Remove prototypes of
7082 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
7083 they are now on lisp.h.
7085 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
7087 * search.c (search_buffer): Use it to inhibit relocation of buffer
7088 text while re_search_2 is doing its job, because re_search_2 is
7089 passed C pointers to buffer text. (Bug#11519)
7091 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
7094 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
7095 state after an additional call to move_it_in_display_line_to, keep
7096 the values of it->max_ascent and it->max_descent found for the
7098 (pos_visible_p): Revert the comparison against bottom_y to what it
7099 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
7102 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
7104 Fix coding-related core dumps with gcc -ftrapv.
7105 The code was computing A - B, where A and B are pointers, and B is
7106 random garbage. This can lead to core dumps on platforms that
7107 have special pointer registers, and it also leads to core dumps on
7108 x86-64 when compiled with gcc -ftrapv. The fix is to compute
7109 A - B only when B is initialized properly.
7110 * coding.c (coding_set_source, coding_set_destination): Return void.
7111 (coding_change_source, coding_change_destinations): New functions,
7112 with the old behaviors of coding_set_source and coding_set_destination.
7113 All callers that need an offset changed to use these new functions.
7115 2012-05-26 Glenn Morris <rgm@gnu.org>
7117 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
7119 2012-05-26 Eli Zaretskii <eliz@gnu.org>
7121 Extend mouse support on W32 text-mode console.
7122 * xdisp.c (draw_row_with_mouse_face):
7123 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
7125 * w32console.c: Include window.h.
7126 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
7128 (initialize_w32_display): Initialize mouse-highlight data.
7130 * w32inevt.c: Include termchar.h and window.h.
7131 (do_mouse_event): Support mouse-autoselect-window. When the mouse
7132 moves, call note_mouse_highlight. If help_echo changed, call
7133 gen_help_event to produce help-echo message in the echo area.
7134 Call clear_mouse_face if mouse_face_hidden is set in the mouse
7137 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
7139 * lread.c (read1): Simplify slightly to avoid an overflow warning
7140 with GCC 4.7.0 on x86-64.
7142 2012-05-26 Eli Zaretskii <eliz@gnu.org>
7144 * bidi.c (bidi_mirror_char): Revert last change: an int is
7145 definitely wide enough here.
7147 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
7149 Fix integer width and related bugs (Bug#9874).

7159 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7160 (allocate_pseudovector):
7161 Use int, not EMACS_INT, where int is wide enough.
7162 (inhibit_garbage_collection, Fgarbage_collect):
7163 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7164 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
7165 int might not be wide enough.
7166 (bidi_cache_search, bidi_cache_find, bidi_init_it)
7167 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
7168 (bidi_at_paragraph_end, bidi_find_paragraph_start)
7169 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
7170 (bidi_level_of_next_char, bidi_move_to_visually_next):
7171 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7172 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
7173 (Fkill_buffer, Fset_buffer_major_mode)
7174 (advance_to_char_boundary, Fbuffer_swap_text)
7175 (Fset_buffer_multibyte, overlays_at, overlays_in)
7176 (overlay_touches_p, struct sortvec, record_overlay_string)
7177 (overlay_strings, recenter_overlay_lists)
7178 (adjust_overlays_for_insert, adjust_overlays_for_delete)
7179 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
7180 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
7181 (Foverlay_recenter, last_overlay_modification_hooks_used)
7182 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
7183 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7184 (validate_region): Omit unnecessary test for b <= e,
7185 since that's guaranteed by the previous test.
7186 (adjust_overlays_for_delete): Avoid pos + length overflow.
7187 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
7188 (report_overlay_modification):
7189 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7190 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
7191 Omit pointer cast, which isn't needed anyway, and doesn't work
7192 after the EMACS_INT -> ptrdiff_t change.
7193 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
7194 * buffer.h: Adjust decls to match defn changes elsewhere.
7195 (struct buffer_text, struct buffer):
7196 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7197 Use EMACS_INT, not int, where int might not be wide enough.
7198 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
7199 not int, to avoid needless 32-bit limit on 64-bit hosts.
7200 (exec_byte_code): Use tighter memory-full test, one that checks
7201 for alloca overflow. Don't compute the address of the object just
7202 before an array, as that's not portable. Use EMACS_INT, not
7203 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
7204 * callint.c (Fcall_interactively):
7205 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7206 * callproc.c (call_process_kill, Fcall_process):
7207 Don't assume pid_t fits into an Emacs fixnum.
7208 (call_process_cleanup, Fcall_process, child_setup):

7215 * casefiddle.c (casify_object, casify_region, operate_on_word)
7216 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
7217 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7218 (casify_object): Avoid integer overflow when overallocating buffer.
7219 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
7220 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
7221 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
7222 * category.h (CATEGORYP): Don't assume arg is nonnegative.
7223 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
7224 integers are now checked earlier. All uses replaced with XINT.
7226 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
7227 For CCL_MapSingle, check that content and value are in int range.

7229 Check that Vcode_version_map_vector is a vector.
7230 (resolve_symbol_ccl_program): Check that vector header is in range.
7231 Always copy the vector, so that we can check its contents reliably
7232 now rather than having to recheck each instruction as it's being
7233 executed. Check that vector words fit in 'int'.
7234 (ccl_get_compiled_code, Fregister_ccl_program)
7235 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
7236 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

7238 contents are in range.
7239 (Fccl_execute_on_string): Check that status is in range.

7283 Don't assume fixnum fits in int.

7931 (x_get_local_selection, x_reply_selection_request)
7932 (x_handle_selection_request, wait_for_property_change):
7933 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7934 (selection_data_to_lisp_data): Use short, not EMACS_INT, where
7935 short is wide enough.
7936 (x_send_client_event): Don't assume fixnum fits in int.
7937 * xterm.c (x_x_to_emacs_modifiers):
7938 Don't assume EMACS_INT overflows nicely into int.
7939 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
7941 (handle_one_xevent): NATNUMP can eval its arg twice.
7942 (x_connection_closed):
7943 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
7944 * xterm.h: Adjust decls to match defn changes elsewhere.
7945 (struct scroll_bar): Use struct vectorlike_header
7946 rather than rolling our own approximation.
7947 (SCROLL_BAR_VEC_SIZE): Remove; not used.
7949 2012-05-25 Glenn Morris <rgm@gnu.org>
7951 * lisp.mk (lisp): Update for more files being compiled now.
7953 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
7955 * lread.c: Remove `read_pure' which makes no difference.
7956 (read_pure): Remove var.
7957 (unreadpure): Remove function.
7958 (readevalloop): Don't call read_list with -1 flag.
7959 (read1, read_vector): Don't test read_pure any more.
7960 (read_list): Simplify.
7962 * fileio.c, character.h: Minor style tweaks.
7964 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
7966 * window.h (clip_changed): Remove useless declaration.
7968 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
7970 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
7971 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
7973 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
7976 This directory predates autoconf and is no longer needed nowadays.
7977 Move its few remaining bits of functionality to where they're needed.
7978 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
7979 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
7980 * m/template.h: Remove.
7981 * Makefile.in (M_FILE): Remove. All uses removed.
7982 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
7983 * lisp.h (USE_LSB_TAG):
7984 * mem-limits.h (EXCEEDS_LISP_PTR):
7985 Use VAL_MAX, not VALBITS, in #if.
7986 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
7987 (EMACS_UINT): Define unconditionally now.
7988 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
7989 (BITS_PER_EMACS_INT): New constants, replacing
7990 what used to be in config.h, but not useful in #if.
7991 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
7992 define them any more.
7993 (VAL_MAX): New macro.
7995 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
7996 BITS_PER_EMACS_INT, in #if.
7997 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
7998 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
7999 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
8000 * s/ms-w32.h (DATA_START):
8001 Move here from removed file m/intel386.h.
8002 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
8003 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
8005 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
8007 Assume C89 or later.
8008 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
8009 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
8011 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
8012 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
8013 * textprop.c, tparam.c (NULL): Remove.
8014 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
8015 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
8016 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
8017 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
8018 * xterm.c (input_signal_count): Assume volatile works.
8020 2012-05-21 Ken Brown <kbrown@cornell.edu>
8022 * xgselect.c (xg_select): Fix first argument in call to 'select'
8025 2012-05-20 Ken Brown <kbrown@cornell.edu>
8027 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
8028 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
8030 2012-05-19 Ken Brown <kbrown@cornell.edu>
8032 * xfns.c (x_in_use): Remove `static' qualifier.
8033 * xterm.h (x_in_use): Declare.
8034 * xgselect.c: Include xterm.h.
8035 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
8036 and `display_arg' (bug#9754).
8038 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
8040 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
8042 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
8043 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
8045 2012-05-18 Eli Zaretskii <eliz@gnu.org>
8047 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
8049 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
8050 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
8052 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
8053 reference to image_cache->refcount.
8054 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
8056 2012-05-17 Juri Linkov <juri@jurta.org>
8058 * search.c (Fword_search_regexp, Fword_search_backward)
8059 (Fword_search_forward, Fword_search_backward_lax)
8060 (Fword_search_forward_lax): Move functions to isearch.el
8061 (bug#10145, bug#11381).
8063 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
8065 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
8067 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
8069 * lread.c (init_obarray): Declare Qt and Qnil as special.
8071 2012-05-14 Glenn Morris <rgm@gnu.org>
8073 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
8074 Put "libexec" before "bin", for the sake of init_callproc_1.
8076 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
8078 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
8080 * unexaix.c: Port to more-recent AIX compilers.
8081 (report_error, report_error_1, make_hdr, copy_sym)
8082 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
8083 Make arguments const char *, not char *, to avoid violations of C
8084 standard and to fix some AIX warnings reported by Gilles Pion.
8086 2012-05-14 Eli Zaretskii <eliz@gnu.org>
8088 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
8089 already have overlays loaded.
8090 (handle_single_display_spec): Before returning without displaying
8091 fringe bitmap, synchronize the bidi iterator with the main display
8092 iterator, by calling iterate_out_of_display_property.
8093 (iterate_out_of_display_property): Detect buffer iteration by
8094 testing that it->string is a Lisp string.
8095 (get_next_display_element): When the current object is exhausted,
8096 and there's something on it->stack, call set_iterator_to_next to
8097 proceed with what's on the stack, instead of returning zero.
8098 (set_iterator_to_next): If called at the end of a Lisp string,
8099 proceed to consider_string_end without incrementing string
8100 position. Don't increment display vector index past the end of
8101 the display vector. (Bug#11417)
8102 (pos_visible_p): Don't report a position visible when move_it_to
8103 stopped at the last line of window, which happens to be scanned
8104 backwards by the bidi iteration. (Bug#11464)
8106 2012-05-14 Eli Zaretskii <eliz@gnu.org>
8108 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
8109 and right-margin display specs even if the spec is invalid or we
8110 are on a TTY, and thus unable to display on the fringes.
8111 That's because the text with the property will not be displayed anyway,
8112 so we need to signal to the caller that this is a "replacing"
8113 display spec. This fixes display when the spec is invalid or we
8116 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
8118 * unexaix.c (make_hdr): Fix typo in prototype.
8119 This bug broke the build on AIX. Problem reported by Gilles Pion.
8121 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
8123 * keyboard.c (kbd_buffer_get_event): Read special events also in
8124 batch mode. (Bug#11415)
8126 2012-05-12 Glenn Morris <rgm@gnu.org>
8128 * ns.mk: Update for ns_appbindir no longer having trailing "/".
8130 2012-05-12 Eli Zaretskii <eliz@gnu.org>
8132 * lisp.mk (lisp): Add newcomment.elc.
8134 2012-05-12 Glenn Morris <rgm@gnu.org>
8136 * Makefile.in (MKDIR_P): New, set by configure.
8137 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
8139 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
8141 Remove unused function hourglass_started.
8142 * dispextern.h (hourglass_started):
8143 * w32fns.c (hourglass_started):
8144 * xdisp.c (hourglass_started): Remove.
8146 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
8148 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
8149 Update dependencies.
8151 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
8153 * xgselect.c (xg_select): Put maxfds+1 into a var.
8154 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
8156 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
8158 2012-05-10 Dave Abrahams <dave@boostpro.com>
8160 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
8161 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
8163 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
8165 * dbusbind.c (xd_registered_buses): New internal Lisp object.
8166 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
8167 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
8168 Initialize xd_registered_buses.
8170 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
8172 Untag more efficiently if USE_LSB_TAG.
8173 This is based on a proposal by YAMAMOTO Mitsuharu in
8174 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
8175 For an admittedly artificial (nth 8000 longlist) benchmark on
8176 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
8177 Emacs's overall text size by 1%.
8178 * lisp.h (XUNTAG): New macro.
8179 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
8180 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
8181 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
8182 * eval.c (Fautoload):
8183 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
8184 * frame.h (XFRAME): Use XUNTAG.
8186 Port recent dbusbind.c changes to 32-bit --with-wide-int.
8187 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
8188 Remove unportable assumptions about print widths of types like
8190 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
8191 intptr_t when converting between pointer and integer, to avoid GCC
8192 warnings about wrong width.
8194 2012-05-09 Eli Zaretskii <eliz@gnu.org>
8196 * w32proc.c (new_child): Force Windows to reserve only 64KB of
8197 stack for each reader_thread, instead of defaulting to 8MB
8198 determined by the linker. This avoids failures in creating
8199 subprocesses on Windows 7, see the discussion in this thread:
8200 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
8202 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
8204 Fix up display of the *Minibuf-0* buffer in the mini window.
8205 * keyboard.c (read_char): Don't clear the echo area if there's no
8207 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
8208 contents of *Minibuf-0*) if there's no message displayed in its stead.
8210 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
8212 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
8215 2012-05-06 Chong Yidong <cyd@gnu.org>
8217 * lisp.mk (lisp): Update.
8219 2012-05-05 Jim Meyering <meyering@redhat.com>
8221 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
8223 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
8225 * data.c (PUT_ERROR): New macro.
8226 (syms_of_data): Use it. Add new error type `user-error'.
8227 * undo.c (user_error): New function.
8228 (Fprimitive_undo): Use it.
8229 * print.c (print_error_message): Adjust print style for `user-error'.
8230 * keyboard.c (user_error): New function.
8231 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
8233 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
8235 Do not limit current-time-string to years 1000..9999.
8236 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
8237 (Fcurrent_time_string): Support any year that is supported by the
8238 underlying localtime representation. Don't use asctime, as it
8239 has undefined behavior for years outside the range -999..9999.
8241 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
8243 Fix race conditions involving setenv, gmtime, localtime, asctime.
8244 Without this fix, interrupts could mess up code that uses these
8245 nonreentrant functions, since setting TZ invalidates existing
8246 tm_zone or tzname values, and since most of these functions return
8247 pointers to static storage.
8248 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
8249 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
8250 Grow the critical sections to include not just invoking
8251 localtime/gmtime, but also accessing these functions' results
8252 including their tm_zone values if any, and any related TZ setting.
8253 (format_time_string): Last arg is now struct tm *, not struct tm **,
8254 so that the struct tm is saved in the critical section.
8255 All callers changed. Simplify allocation of initial buffer, partly
8256 motivated by the fact that memory allocation needs to be outside
8257 the critical section.
8259 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
8261 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
8262 with RESET_INTERVAL.
8264 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
8265 Remove duplicated buffer name initialization.
8267 2012-05-02 Jim Meyering <jim@meyering.net>
8269 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
8271 * xfns.c (x_window): Use xstrdup (Bug#11375).
8273 2012-05-02 Eli Zaretskii <eliz@gnu.org>
8275 * xdisp.c (pos_visible_p): If already at a newline from the
8276 display string before the 'while' loop, don't walk back the glyphs
8277 from it3.glyph_row. Solves assertion violation when the display
8278 string begins with a newline (egg.el). (Bug#11367)
8280 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
8282 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
8285 2012-05-01 Glenn Morris <rgm@gnu.org>
8287 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
8288 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
8289 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
8290 All were removed before 23.1.
8292 * dispnew.c: Remove HAVE_LIBNCURSES test;
8293 it is always true on relevant platforms.
8295 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
8296 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
8298 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
8300 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
8302 * .gdbinit (xpr): Remove checks for no longer existing misc types.
8303 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
8306 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
8308 Do not avoid creating empty evaporating overlays (Bug#9642).
8309 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
8310 That is, do not delete an evaporating overlay if it becomes
8311 empty after its bounds are adjusted to fit within its buffer.
8312 This fix caused other problems, and I'm reverting it until we get
8313 to the bottom of them.
8315 2012-04-27 Chong Yidong <cyd@gnu.org>
8317 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
8319 2012-04-27 Eli Zaretskii <eliz@gnu.org>
8321 * xdisp.c (pos_visible_p): If the window start position is beyond
8322 ZV, start the display from buffer beginning. Prevents assertion
8323 violation in init_iterator when the minibuffer window is scrolled
8326 * window.c (window_scroll_pixel_based): Likewise.
8328 2012-04-27 Chong Yidong <cyd@gnu.org>
8330 * keymap.c (where_is_internal): Doc fix (Bug#10872).
8332 2012-04-27 Glenn Morris <rgm@gnu.org>
8334 * fileio.c (Fcopy_file, Fset_file_selinux_context):
8335 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
8337 2012-04-27 Eli Zaretskii <eliz@gnu.org>
8339 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
8340 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
8342 2012-04-26 Eli Zaretskii <eliz@gnu.org>
8344 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
8345 display element, check also the underlying string or buffer
8346 character. (Bug#11341)
8348 * w32menu.c: Include w32heap.h.
8349 (add_menu_item): If the call to AppendMenuW (via
8350 unicode_append_menu) fails, disable Unicode menus only if we are
8351 running on Windows 9X/Me.
8353 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
8355 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
8356 (xgetint): Add missing shift for LSB tags.
8358 2012-04-24 Martin Rudalics <rudalics@gmx.at>
8360 * keyboard.c (read_char): Don't wipe echo area for select window
8361 events: These might get delayed via `mouse-autoselect-window'
8364 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
8366 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
8367 manipulation of :loaded-from data.
8369 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
8371 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
8372 now a cons (bug#11311).
8374 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
8376 Do not create empty overlays with the evaporate property (Bug#9642).
8377 * buffer.c (Fmove_overlay): Delete an evaporating overlay
8378 if it becomes empty after its bounds are adjusted to fit within
8379 its buffer. Without this fix, in a nonempty buffer (let ((o
8380 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
8381 yields an empty overlay that has the evaporate property, which is
8382 not supposed to happen.
8384 Fix minor GTK3 problems found by static checking.
8385 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
8386 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
8387 (struct _EmacsFixedClass, emacs_fixed_get_type):

8486 since the two debugging options are incompatible.
8487 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
8489 (mem_init, mem_insert, mem_insert_fixup):
8490 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

8583 New extern decls, to avoid calling undeclared functions.
8584 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
8585 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
8586 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

8656 2012-04-11 Daniel Colascione <dancol@dancol.org>
8658 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
8659 against is gone. It's better to use vfork now so that when Cygwin
8660 gains a new, working vfork, we use it automatically (bug#10398).
8662 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

8717 2012-04-09 Eli Zaretskii <eliz@gnu.org>
8719 * xdisp.c (set_cursor_from_row): If the display string appears in
8720 the buffer at position that is closer to point than the position
8721 after the display string, display the cursor on the first glyph of
8722 the display string. Fixes cursor display when a 'display' text
8723 property immediately follows invisible text. (Bug#11094)
8725 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
8727 composite.c: use 'double' consistently
8728 * composite.c (get_composition_id): Use 'double' consistently
8729 instead of converting 'float' to 'double' and vice versa; this is
8730 easier to understand and avoids a GCC warning.

8779 [!WINDOWSNT]: New macros.
8780 (init_libxml2_functions, libxml2_loaded_p): New functions.
8781 (parse_region): Call fn_xmlCheckVersion instead of using the macro
8782 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.

8804 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
8805 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
8806 about subtle differences between FETCH_CHAR* and STRING_CHAR*
8807 macros related to unification of CJK characters. For the details,
8808 see the discussion following the message here:
8809 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
8811 2012-04-04 Chong Yidong <cyd@gnu.org>

8827 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
8828 position we get to after a call to move_it_to fails the
8829 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
8830 only if we wind up in a string from display property. (Bug#11063)
8832 * window.c (Fdelete_other_windows_internal): Invalidate the row
8833 and column information about mouse highlight, so that redisplay
8834 restores it after reallocating the glyph matrices. (Bug#7464)
8836 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
8837 string comes from a `display' text property, use the buffer
8838 position of that property as if we actually saw that position in
8840 (move_it_by_lines): Remove the assertion that
8841 "it->current_x == 0 && it->hpos == 0" which can be legitimately
8842 violated when there's a before-string at the beginning of a line.
8845 2012-03-30 Eli Zaretskii <eliz@gnu.org>
8847 * xdisp.c (append_space_for_newline): If the default face was
8848 remapped, use the remapped face for the appended newline.
8849 (extend_face_to_end_of_line): Use the remapped default face for
8850 extending the face to the end of the line.
8851 (display_line): Call extend_face_to_end_of_line when the default
8852 face was remapped. (Bug#11068)
8854 2012-03-29 Eli Zaretskii <eliz@gnu.org>
8856 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
8858 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
8860 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
8862 2012-03-27 Glenn Morris <rgm@gnu.org>
8864 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
8867 2012-03-26 Kenichi Handa <handa@m17n.org>
8869 * dispextern.h (struct glyph): Fix previous change. Change the
8870 bit length of glyphless.ch to 25 (Bug#11082).
8872 2012-03-26 Chong Yidong <cyd@gnu.org>
8874 * keyboard.c (Vselection_inhibit_update_commands): New variable.
8875 (command_loop_1): Use it; inhibit selection update for
8876 handle-select-window too (Bug#8996).
8878 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
8880 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
8882 2012-03-25 Kenichi Handa <handa@m17n.org>
8884 * dispextern.h (struct glyph): Change the bit length of
8885 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
8887 2012-03-24 Eli Zaretskii <eliz@gnu.org>
8889 * s/ms-w32.h (tzname): Include time.h before redirecting to
8890 _tzname. Fixes the MSVC build. (Bug#9960)
8892 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
8894 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
8897 * xterm.c (XTread_socket): Only modify handling_signal if
8898 !SYNC_INPUT. (Bug#11080)
8900 2012-03-23 Eli Zaretskii <eliz@gnu.org>
8902 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
8903 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
8904 when fetching a multibyte character consumes more bytes than
8905 CHAR_BYTES returns, due to unification of CJK characters in
8906 string_char. (Bug#11073)
8908 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
8910 * process.c (wait_reading_process_output): Handle pty disconnect
8911 by refraining from sending oneself a SIGCHLD (bug#10933).
8913 2012-03-22 Chong Yidong <cyd@gnu.org>
8915 * dispextern.h (struct it): New member string_from_prefix_prop_p.
8917 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
8918 Mark string as coming from a prefix property.
8919 (handle_face_prop): Use default face for prefix strings (Bug#4281).
8920 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
8922 2012-03-21 Chong Yidong <cyd@gnu.org>
8924 * xfaces.c (Vface_remapping_alist): Doc fix.
8926 2012-03-20 Eli Zaretskii <eliz@gnu.org>
8928 * w32proc.c (Fw32_set_console_codepage)
8929 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
8932 2012-03-20 Chong Yidong <cyd@gnu.org>
8934 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
8935 to reflect default non-nil value of redisplay-dont-pause.
8937 2012-03-19 Kenichi Handa <handa@m17n.org>
8939 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
8940 it fit in a valid range (Bug#11003).
8942 2012-03-18 Eli Zaretskii <eliz@gnu.org>
8944 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
8945 that is not from display property, accept the row as a "cursor
8946 row" if one of the string's character has a non-nil `cursor'
8947 property. Fixes cursor positioning when there are newlines in
8948 overlay strings, e.g. in icomplete.el. (Bug#11035)
8950 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
8952 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
8954 2012-03-12 Chong Yidong <cyd@gnu.org>
8956 * eval.c (inhibit_lisp_code): Rename from
8957 inhibit_window_configuration_change_hook; move from window.c.
8959 * xfns.c (unwind_create_frame_1, Fx_create_frame):
8960 * window.c (run_window_configuration_change_hook)
8961 (syms_of_window): Callers changed.
8963 2012-03-11 Chong Yidong <cyd@gnu.org>
8965 * keymap.c (Fkey_description): Doc fix (Bug#9700).

8972 is visible (Bug#10955).
8974 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
8976 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
8978 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
8980 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
8981 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
8984 2012-03-03 Glenn Morris <rgm@gnu.org>
8986 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
8988 2012-03-02 Eli Zaretskii <eliz@gnu.org>
8990 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
8991 position past the first glyph_row that ends at ZV. (Bug#10902)
8992 (redisplay_window, next_element_from_string): Fix typos in
8994 (redisplay_window): Pass to move_it_vertically the margin in
8995 pixels, not in screen lines.
8997 2012-03-02 Glenn Morris <rgm@gnu.org>
8999 * buffer.c (buffer-list-update-hook): Doc fix.
9001 2012-02-29 Eli Zaretskii <eliz@gnu.org>
9003 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
9004 push_it before setting up the iterator for the first overlay
9005 string, even if we have an empty string loaded.
9006 (next_overlay_string): If there's an empty string on the iterator
9007 stack, pop the stack. (Bug#10903)
9009 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
9011 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
9012 Suggested by Stefan Monnier in
9013 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
9014 * alloc.c (widen_to_Lisp_Object): New static function.
9015 (mark_memory): Also mark Lisp_Objects by fetching pointer words
9016 and widening them to Lisp_Objects. This would work even if
9017 USE_LSB_TAG is defined and wide integers are used, which might
9018 happen in a future version of Emacs.
9020 2012-02-25 Chong Yidong <cyd@gnu.org>
9022 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
9025 * xselect.c (Fx_selection_exists_p): Doc fix.
9026 (x_clipboard_manager_save_all): Print an informative message
9027 before saving to clipboard manager.
9029 2012-02-24 Chong Yidong <cyd@gnu.org>
9031 * keyboard.c (process_special_events): Handle all X selection
9032 requests in kbd_buffer, not just the next one (Bug#8869).
9034 2012-02-23 Chong Yidong <cyd@gnu.org>
9036 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
9037 call when setting menu-bar-lines and tool-bar-lines parameters.
9038 (unwind_create_frame_1): New helper function.
9040 * window.c (inhibit_window_configuration_change_hook): New var.
9041 (run_window_configuration_change_hook): Obey it.
9042 (syms_of_window): Initialize it.
9044 2012-02-22 Chong Yidong <cyd@gnu.org>
9046 * xterm.c (x_draw_image_relief): Add missing type check for
9047 Vtool_bar_button_margin (Bug#10743).
9049 2012-02-21 Chong Yidong <cyd@gnu.org>
9051 * fileio.c (Vfile_name_handler_alist): Doc fix.
9053 * buffer.c (Fget_file_buffer): Protect against invalid file
9054 handler return value.
9056 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
9058 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
9059 when computing $valmask.
9061 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
9062 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
9063 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
9064 It's useless in that case, and it can cause problems on hosts
9065 that allocate halves of EMACS_INT values separately.
9066 Reported by Dan Horák. Diagnosed by Andreas Schwab in
9067 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
9068 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
9069 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
9070 it avoids undefined behavior on hosts where shifting right by more
9071 than the word width has undefined behavior.
9073 2012-02-19 Chong Yidong <cyd@gnu.org>
9075 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
9076 (Funhandled_file_name_directory, Ffile_name_as_directory)
9077 (Fdirectory_file_name, Fexpand_file_name)
9078 (Fsubstitute_in_file_name): Protect against invalid file handler
9079 return values (Bug#10845).
9081 2012-02-18 Eli Zaretskii <eliz@gnu.org>
9083 * .gdbinit (pitx): Fix incorrect references to fields of the
9086 2012-02-17 Chong Yidong <cyd@gnu.org>
9088 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
9090 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
9092 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
9093 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
9095 2012-02-15 Chong Yidong <cyd@gnu.org>
9097 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
9098 marked as special. Also, starting docstrings with * is obsolete.
9100 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
9102 * gnutls.c (emacs_gnutls_write): Fix last change.
9104 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
9106 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
9109 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>

9113 2012-02-12 Chong Yidong <cyd@gnu.org>
9115 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
9116 as that creates a dangerous corner case.
9118 * window.c (Fdelete_window_internal): Invalidate the mouse
9119 highlight (Bug#9904).
9121 2012-02-12 Glenn Morris <rgm@gnu.org>
9123 * xselect.c (Fx_own_selection_internal)
9124 (Fx_get_selection_internal, Fx_disown_selection_internal)
9125 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
9126 * nsselect.m (Fx_own_selection_internal)
9127 (Fx_disown_selection_internal, Fx_selection_exists_p)
9128 (Fx_selection_owner_p, Fx_get_selection_internal):
9129 Sync docs and argument specs with the xselect.c versions.
9131 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
9133 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

9147 2012-02-09 Kenichi Handa <handa@m17n.org>
9149 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
9151 2012-02-07 Chong Yidong <cyd@gnu.org>
9153 * buffer.c (Fbuffer_local_variables)
9154 (buffer_lisp_local_variables): Handle unbound vars correctly;
9155 don't let Qunbound leak into Lisp.
9157 2012-02-07 Glenn Morris <rgm@gnu.org>
9159 * image.c (Fimagemagick_types): Doc fix.
9161 * image.c (imagemagick-render-type): Change it from a lisp object
9162 to an integer. Move the doc here from the lisp manual.
9163 Treat all values not equal to 0 the same.
9165 2012-02-06 Chong Yidong <cyd@gnu.org>
9167 * doc.c (store_function_docstring): Avoid applying docstring of
9168 alias to base function (Bug#2603).
9170 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
9172 * .gdbinit (pp1, pv1): Remove redundant defines.
9175 2012-02-04 Chong Yidong <cyd@gnu.org>
9177 * nsterm.m: Declare a global (Bug#10694).
9179 2012-02-04 Eli Zaretskii <eliz@gnu.org>
9181 * w32.c (get_emacs_configuration_options):
9182 Include --enable-checking, if specified, in the return value.
9184 2012-02-04 Martin Rudalics <rudalics@gmx.at>
9186 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
9187 after rounding frame sizes. (Bug#9723)
9189 2012-02-04 Eli Zaretskii <eliz@gnu.org>
9191 * keyboard.c (adjust_point_for_property): Don't position point
9192 before BEGV. (Bug#10696)
9194 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
9196 Handle overflow when computing char display width (Bug#9496).
9197 * character.c (char_width): Return EMACS_INT, not int.
9198 (char_width, c_string_width): Check for overflow when
9199 computing the width; this is possible now that individual
9200 characters can have unbounded width. Problem introduced
9201 by merge from Emacs 23 on 2012-01-19.
9203 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
9205 * dbusbind.c (Fdbus_register_method): Mention the return value
9206 :ignore in the docstring.
9208 2012-02-02 Glenn Morris <rgm@gnu.org>
9210 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.

9218 2012-02-02 Kenichi Handa <handa@m17n.org>
9220 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
9221 0, do not call append_composite_glyph.
9223 2012-02-02 Kenichi Handa <handa@m17n.org>
9225 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
9227 (x_produce_glyphs): If the component of a composition is a null
9228 string, set it->pixel_width to 1 to avoid zero-width glyph.
9230 2012-02-01 Eli Zaretskii <eliz@gnu.org>
9232 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
9233 first 2 arguments are identical. This makes inserting large
9234 output from a subprocess an order of magnitude faster on
9235 MS-Windows, where all sbrk'ed memory is always contiguous.
9237 2012-01-31 Glenn Morris <rgm@gnu.org>
9239 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

9247 2012-01-28 Samuel Thibault <sthibault@debian.org> (tiny change)
9249 * s/gnu.h: Define POSIX_SIGNALS (Bug#10552).
9251 2012-01-28 Chong Yidong <cyd@gnu.org>
9253 * minibuf.c (syms_of_minibuf): Doc fix (Bug#10550).
9255 2012-01-26 Chong Yidong <cyd@gnu.org>

9275 2012-01-21 Chong Yidong <cyd@gnu.org>
9277 * floatfns.c (Fcopysign): Make the second argument non-optional,
9278 since nil is not allowed anyway.
9280 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
9282 * process.c (read_process_output): Use p instead of XPROCESS (proc).
9283 (send_process): Likewise.
9285 2012-01-19 Martin Rudalics <rudalics@gmx.at>
9287 * window.c (save_window_save, Fcurrent_window_configuration)

9289 Rewrite doc-strings.
9291 2012-01-19 Kenichi Handa <handa@m17n.org>
9293 * character.c (char_width): New function.
9294 (Fchar_width, c_string_width, lisp_string_width):
9295 Use char_width (Bug#9496).
9297 2012-01-16 Martin Rudalics <rudalics@gmx.at>
9299 * window.c (Vwindow_persistent_parameters): New variable.
9300 (Fset_window_configuration, save_window_save): Handle persistent
9303 2012-01-14 Eli Zaretskii <eliz@gnu.org>
9305 * w32fns.c (signal_user_input): Don't do a QUIT, to avoid
9306 thrashing the stack of the thread. (Bug#9087)
9308 2012-01-12 Paul Eggert <eggert@cs.ucla.edu>
9310 * xdisp.c (rows_from_pos_range): Add parens as per gcc -Wparentheses.

9315 highlight ends on a newline. (Bug#10464)
9316 (mouse_face_from_buffer_pos): Fix off-by-one error in calculating
9317 he end column for display of highlight that ends on a newline
9320 2012-01-11 Glenn Morris <rgm@gnu.org>
9322 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
9323 from load-path also when installation-directory is nil. (Bug#10208)
9325 2012-01-10 Glenn Morris <rgm@gnu.org>
9327 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.
9329 * epaths.in (PATH_LOADSEARCH, PATH_EXEC, PATH_DATA, PATH_DOC):
9330 Update template values to be closer to their typical values these days.
9332 2012-01-09 Eli Zaretskii <eliz@gnu.org>
9334 * xdisp.c (rows_from_pos_range): Accept additional argument
9335 DISP_STRING, and accept any glyph in a row whose object is that
9336 string as eligible for mouse highlight. Fixes mouse highlight of
9337 display strings from overlays. (Bug#10464)
9339 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
9341 emacs: fix an auto-save permissions race condition (Bug#10400)
9342 * fileio.c (auto_saving_dir_umask): New static var.
9343 (Fmake_directory_internal): Use it.
9344 (do_auto_save_make_dir): Set it, instead of invoking chmod after
9345 creating the directory. The old code temporarily assigns

9848 2011-11-20 Paul Eggert <eggert@cs.ucla.edu>
9850 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
9851 Otherwise, valgrind does not work on some platforms.
9852 Problem reported by Andreas Schwab in
9853 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
9854 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
9855 is set, removing the need for VIRT_ADDRESS_VARIES.
9856 (PURE_P): Use a more-efficient implementation that needs just one
9857 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
9858 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
9859 to 4 (xorl, subq, cmpq, setbe).
9860 * alloc.c (pure): Always extern now, since that's the
9861 VIRT_ADDR_VARIES behavior.
9862 (PURE_POINTER_P): Use a single comparison, not two, for
9863 consistency with the new puresize.h.
9864 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
9865 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

9871 (erase_phys_cursor, update_window_cursor, show_mouse_face)
9872 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
9873 behave as if the cursor position were at the window margin.
9875 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
9876 and the cursor position is out of bounds, behave as if the cursor
9877 position were at the window margin. (Bug#10075)
9879 2011-11-18 Chong Yidong <cyd@gnu.org>
9881 * window.c (Fwindow_combination_limit): Make first argument

9903 compute_line_metrics.
9904 (compute_line_metrics): Call row_hash, instead of computing the
9907 * dispnew.c (verify_row_hash): Call row_hash for computing the
9908 hash code of a row, instead of duplicating code from xdisp.c.
9910 * dispextern.h (row_hash): Add prototype.
9912 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

9946 * image.c (imagemagick_load_image): Fix typo.
9948 2011-11-14 Eli Zaretskii <eliz@gnu.org>
9950 * xdisp.c (display_line): Move the call to
9951 highlight_trailing_whitespace before the call to
9952 compute_line_metrics, since the latter needs to see the final
9953 faces of all the glyphs to compute ROW's hash value.
9954 Fixes assertion violations in row_equal_p. (Bug#10035)
9956 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
9958 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

9963 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
9964 with user-defined heap size. Bump the default size of the temacs

10015 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
10017 Avoid some portability problems by eschewing 'extern inline' functions.
10018 The trivial performance wins aren't worth the portability hassles; see
10019 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
10021 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

10029 (copy_intervals_to_string): No longer inline.
10030 * xdisp.c (window_text_bottom_y, window_box_width)

10087 * xmenu.c (cleanup_widget_value_tree): New function.
10088 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
10089 calling free_menubar_widget_value_tree directly (Bug#9830).

10095 (window_box_width, window_box_left, window_box_left_offset)
10096 (window_box_right, window_box_right_offset): Declare extern.
10097 Otherwise, these inline functions do not conform to C99 and
10098 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
10099 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
10100 * intervals.c (adjust_intervals_for_insertion)

10103 (static_offset_intervals): Remove.
10104 (offset_intervals): Rewrite using the old contents of
10105 static_offset_intervals. The old version didn't conform to C99
10106 because an extern inline function contained a reference to an
10107 identifier with static linkage.

10160 (unwind_create_frame): New function (Bug#9943).
10161 (Fx_create_frame): Restructure code to be more similar to the one in
10162 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).

10297 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
10299 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
10302 2011-10-29 Glenn Morris <rgm@gnu.org>
10304 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
10305 Not clear what it was for, and it causes various bugs. (Bug#9839)
10307 2011-10-28 Eli Zaretskii <eliz@gnu.org>
10309 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
10310 possible random value that matches one of those tested as
10311 condition to clear the mouse face.
10313 2011-10-28 Chong Yidong <cyd@gnu.org>
10315 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
10317 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
10319 * window.c (make_window): Initialize phys_cursor_on_p.
10321 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
10323 * lisp.h (struct Lisp_Symbol): Update comments.
10325 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
10327 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
10329 2011-10-28 Eli Zaretskii <eliz@gnu.org>
10331 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
10332 <oslsachem@gmail.com> for helping to debug this.
10334 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
10335 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
10336 (g_b_init_get_glyph_outline_w): New static variables.
10337 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
10338 (GetGlyphOutlineW_Proc): New typedefs.
10339 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
10340 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
10342 (w32font_open_internal, compute_metrics):
10343 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
10344 instead of calling the "wide" APIs directly.
10346 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
10348 * w32.h (syms_of_w32font): Add prototype.
10350 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
10352 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
10353 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
10354 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
10355 (Fmove_to_window_line): Doc fix.
10357 2011-10-27 Chong Yidong <cyd@gnu.org>
10359 * process.c (make_process): Set gnutls_state to NULL.
10361 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
10362 non-NULL, regardless of GNUTLS_INITSTAGE.
10363 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
10364 an error. Set process slots as soon as we allocate them.
10366 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
10368 2011-10-27 Chong Yidong <cyd@gnu.org>
10370 * gnutls.c (emacs_gnutls_deinit): New function.
10371 Deallocate credentials structures as well as calling gnutls_deinit.
10372 (Fgnutls_deinit, Fgnutls_boot): Use it.
10374 * process.c (make_process): Initialize GnuTLS credentials to NULL.
10375 (deactivate_process): Call emacs_gnutls_deinit.
10377 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
10379 * image.c (x_create_x_image_and_pixmap):
10380 * w32.c (sys_rename, w32_delayed_load):
10381 * w32font.c (fill_in_logfont):
10382 * w32reg.c (x_get_string_resource): Silence compiler warnings.
10384 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
10386 * w32fns.c (w32_default_color_map): New function,
10387 extracted from Fw32_default_color_map.
10388 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
10390 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
10392 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
10394 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
10396 * keyboard.c (test_undefined): New function (bug#9751).
10397 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
10399 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
10401 * sysdep.c (init_sys_modes): Fix the check for the controlling
10402 terminal (Bug#6649).
10404 2011-10-20 Eli Zaretskii <eliz@gnu.org>
10406 * dispextern.h (struct bidi_it): New member next_en_type.
10408 * bidi.c (bidi_line_init): Initialize the next_en_type member.
10409 (bidi_resolve_explicit_1): When next_en_pos is valid for the
10410 current character, check also for next_en_type being WEAK_EN.
10411 (bidi_resolve_weak): Don't enter the expensive loop if the current
10412 position is before next_en_pos. Record the bidi type of the first
10413 non-ET, non-BN character we find, in addition to its position.
10414 (bidi_level_of_next_char): Invalidate next_en_type when
10415 next_en_pos is over-stepped.
10417 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
10419 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
10420 * editfns.c: Rewrite current-time-zone so that it invokes
10421 the equivalent of (format-time-string "%Z") to get the time zone name.
10422 This fixes a bug when the time zone name contains characters that
10423 need converting from the system time locale to Emacs internal format.
10424 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
10425 that patch fixed format-time-string to do the conversion, but
10426 I forgot to fix current-time-zone.
10427 (format_time_string): New function, containing most of
10428 what Fformat_time_string used to contain.
10429 (Fformat_time_string): Rewrite in terms of format_time_string.
10430 This doesn't change this function's behavior.
10431 (current-time-zone): Rewrite to use format_time_string.
10432 This fixes the bug reported by Michael Schierl in
10433 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
10434 Jason Rumney's 2007-06-07 change worked around this bug, but
10436 * systime.h (tzname, timezone): Remove no-longer-used declarations.
10438 2011-10-19 Eli Zaretskii <eliz@gnu.org>
10440 * xdisp.c (start_display): If the character at POS is displayed
10441 via a display vector, reset IT->current.dpvec_index to zero.
10442 (try_window_reusing_current_matrix): If a line ends in a display
10443 vector or the next line starts in a display vector, continue
10444 redrawing the window even though the character position of
10445 start_row was reached.
10448 2011-10-18 Chong Yidong <cyd@gnu.org>
10450 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
10451 with nobreak-char-display too.
10453 2011-10-18 Eli Zaretskii <eliz@gnu.org>
10455 Fix part 3 of bug#9771.
10456 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
10457 (bidi_resolve_neutral): Don't enter the expensive loop looking for
10458 non-neutral characters if the current character is a paragraph
10459 separator (a.k.a. Newline). This avoids running the same
10460 expensive loop twice, once when we consume the preceding newline
10461 and the other time when the line actually needs to be displayed.
10462 Avoid the loop when we see neutrals on the base embedding level
10463 following a character whose directionality is the same as the
10464 paragraph's. This avoids running the expensive loop when a line
10465 ends in a long sequence of neutrals, like control characters.
10466 Add assertion against STRONG_AL type. Slightly rearrange code
10467 that determines the type of a neutral given the first non-neutral
10469 (bidi_level_of_next_char): Set next_en_pos to zero when
10470 invalidating its info.
10472 2011-10-17 Eli Zaretskii <eliz@gnu.org>
10474 * xdisp.c (push_display_prop): Determine whether to record string
10475 or buffer position by IT->string, not by IT->method. Allow
10476 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
10477 (move_it_vertically_backward): Don't look for character position
10478 immediately after the newline when in a continuation line.
10481 2011-10-15 Martin Rudalics <rudalics@gmx.at>
10483 * window.c (coordinates_in_window): Rewrite and delabelize
10484 vertical border check. (Bug#5357) (Bug#9618)
10486 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
10488 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
10489 errors in XSetWindowBorder (bug#9310).
10491 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
10493 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
10494 avoid crash when xmalloc overrun checking is enabled.
10496 2011-10-13 Eli Zaretskii <eliz@gnu.org>
10498 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
10499 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
10500 cursor motion with <left> and <right> arrow keys.
10502 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
10503 some callers set that themselves.
10505 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10507 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
10508 display string and the previous row comes from the same string and
10509 is empty. (Bug#9739) (Bug#9738)
10511 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
10513 * doc.c (get_doc_string): Encode file name (bug#9735).
10515 2011-10-12 Eli Zaretskii <eliz@gnu.org>
10517 * bidi.c (bidi_level_of_next_char):
10518 * xdisp.c (get_visually_first_element): Remove old incorrect
10519 comments regarding the Unicode Line Separator character.
10521 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
10523 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
10525 * alloc.c (Fgc_status): Do not access beyond zombies array
10526 boundary if nzombies > MAX_ZOMBIES.
10527 * alloc.c (dump_zombies): Add missing format specifier.
10529 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
10531 * xdisp.c (set_cursor_from_row): Simplify conditionals,
10532 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
10534 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
10535 Some packages use them to denote characters with modifiers.
10537 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
10539 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
10540 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
10541 matching a pp-number. Rename parameter var to var1.
10543 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
10545 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
10547 2011-10-08 Glenn Morris <rgm@gnu.org>
10549 * callint.c (Fcall_interactively): Give a more explicit error for the
10550 'c' case with a non-character input. (Bug#8479)
10552 2011-10-08 Eli Zaretskii <eliz@gnu.org>
10554 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
10556 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
10557 lines that are hscrolled on the left.
10559 * dispnew.c (buffer_posn_from_coords): Account for a possible
10560 presence of header-line. (Bug#4426)
10562 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
10564 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
10565 Don't advertise functionality which we discourage or doesn't work.
10567 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
10569 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
10570 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
10571 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
10572 this makes Emacs dump core during garbage collection on rare
10573 occasions. sizeof is obviously inferior to offsetof here, so
10574 stick with offsetof.
10575 (GC_POINTER_ALIGNMENT): New macro.
10576 (mark_memory): Omit 3rd (offset) arg; caller changed.
10577 Don't assume EMACS_INT alignment is the same as pointer alignment.
10579 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
10581 * keyboard.c (read_key_sequence_remapped): New var.
10582 (read_key_sequence): Compute remapping in the right buffer.
10583 (command_loop_1): Use read_key_sequence's remapping directly.
10585 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
10587 * dired.c (file_name_completion): Don't expand file name.
10588 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
10589 before checking file name handler.
10591 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
10592 they've been requested explicitly (bug#9591).
10594 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
10596 * keymap.c (Fsingle_key_description): Use make_specified_string
10597 instead of build_string to build string from push_key_description.
10600 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10602 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
10603 This fixes a Y2038 bug on 64-bit hosts.
10604 * buffer.c (reset_buffer):
10605 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
10606 (Fclear_buffer_auto_save_failure):
10607 Use 0, not -1, to represent an unset failure time, since time_t
10608 might not be signed.
10610 Remove dependency on glibc malloc internals.
10611 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10612 Move back here from lisp.h, but with their new implementations.
10613 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10614 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
10615 * charset.c (charset_table_init): New static var.
10616 (syms_of_charset): Use it instead of xmalloc. This removes a
10617 dependency on glibc malloc internals. See Eli Zaretskii's comment in
10618 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
10619 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10620 Move back to alloc.c.
10621 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10622 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
10624 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
10626 * nsterm.m (windowDidResize): Call x_set_window_size only when
10627 ns_in_resize is true. Otherwise set pixelwidth/height and
10628 call change_frame_size (Bug#9628).
10630 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
10632 Port --enable-checking=all to Fedora 14 x86-64.
10633 * charset.c (syms_of_charset): Also account for glibc malloc's
10634 internal overhead when calculating the initial malloc maximum.
10636 Port --enable-checking=all to Fedora 14 x86.
10637 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10639 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
10640 (overrun_check_realloc, overrun_check_free):
10641 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
10642 That way, xmalloc returns a properly-aligned pointer even if
10643 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
10644 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
10645 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
10646 into account when calculating the initial malloc maximum.
10647 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
10648 Move here from alloc.c, so that charset.c can use it too.
10649 Properly align; the old code wasn't right for common 32-bit hosts
10650 when configured with --enable-checking=all.
10651 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
10652 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
10654 2011-09-29 Eli Zaretskii <eliz@gnu.org>
10656 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
10659 2011-09-28 Eli Zaretskii <eliz@gnu.org>
10661 * xdisp.c (compute_display_string_end): If there's no display
10662 string at CHARPOS, return -1.
10664 * bidi.c (bidi_fetch_char): When compute_display_string_end
10665 returns a negative value, treat the character as a normal
10666 character not covered by a display string. (Bug#9624)
10668 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
10670 * lread.c (Fread_from_string): Fix typo in docstring.
10672 2011-09-27 Eli Zaretskii <eliz@gnu.org>
10674 * xdisp.c (handle_invisible_prop): If invisible text ends on a
10675 newline, reseat the iterator instead of bidi-iterating there one
10676 character at a time. (Bug#9610)
10677 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
10678 TO_CHARPOS if the bidi iterator is at base embedding level.
10680 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
10682 * lread.c (readevalloop): Use correct code for NBSP.
10683 (read1): Likewise. (Bug#9608)
10685 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
10687 * dbusbind.c (Fdbus_register_signal): When service is not
10688 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
10690 2011-09-25 Glenn Morris <rgm@gnu.org>
10692 * buffer.c (truncate-lines): Doc fix.
10694 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
10696 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
10697 (Fset_window_next_buffers): Doc fix.
10699 2011-09-24 Glenn Morris <rgm@gnu.org>
10701 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
10703 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
10705 Fix minor problems found by static checking.
10706 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
10707 * indent.c (Fvertical_motion): Fix == vs = typo.
10709 2011-09-24 Eli Zaretskii <eliz@gnu.org>
10711 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
10712 Default value is now t. Doc fix.
10714 * indent.c (Fvertical_motion): Compute and apply the overshoot
10715 logic when moving up, not only when moving down. Fix the
10716 confusing name and values of the it_overshoot_expected variable;
10717 logic changes accordingly. (Bug#9254) (Bug#9549)
10719 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
10720 CHARPOS is covered by a display string which includes newlines.
10721 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
10722 is covered by a display string with embedded newlines.
10724 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
10726 * dbusbind.c (Fdbus_register_signal): Add match rule to
10727 Vdbus_registered_objects_table. (Bug#9581)
10728 (Fdbus_register_method, Vdbus_registered_objects_table):
10731 2011-09-24 Jim Meyering <meyering@redhat.com>
10733 do not ignore write error for any output size
10734 The previous change was incomplete.
10735 While it makes emacs --batch detect the vast majority of stdout
10736 write failures, errors were still ignored whenever the output size is
10737 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
10738 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
10739 && echo FAIL: ignored write error
10740 FAIL: ignored write error
10741 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
10742 && echo FAIL: ignored write error
10743 FAIL: ignored write error

10746 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
10748 * emacs.c (Fkill_emacs): In noninteractive mode exit
10749 non-successfully if a write error occurred on stdout. (Bug#9574)

10753 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
10756 * dispextern.h (struct it): Update the comment documenting what
10759 2011-09-20 Eli Zaretskii <eliz@gnu.org>
10761 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
10762 a display string, extend search for cursor position to end of row.
10763 (find_row_edges): If the row ends in a newline from a display
10764 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
10765 Handle the case of a display string with multiple newlines.
10766 (Fcurrent_bidi_paragraph_direction): Fix search for previous
10767 non-empty line. Fixes confusing cursor motion with arrow keys at
10768 the beginning of a line that starts with whitespace.
10770 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
10772 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
10775 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
10777 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
10778 boolean (Bug#9154).
10780 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10782 * xdisp.c (display_line): Record maximum and minimum buffer
10783 positions even if no glyphs were produced (e.g., by a zero-width
10784 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
10785 buffer positions that will be removed from the glyph row because
10787 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
10788 column is beyond frame width: don't subtract 1 "pixel" when
10789 computing width of the stretch.
10790 (reseat_at_next_visible_line_start): Undo the change made on
10791 2011-09-17 that saved paragraph information and restored it after
10792 the call to `reseat'. (Bug#9545)
10794 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10796 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
10797 and turn window cursor on if cleared (Bug#9415).
10799 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
10801 * search.c (boyer_moore): Take unibyte characters from pattern
10802 literally. (Bug#9458)
10804 2011-09-18 Eli Zaretskii <eliz@gnu.org>

10808 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
10810 Fix minor problem found by static checking.
10811 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
10812 initialized, to pacify gcc -Wuninitialized.
10814 * fileio.c: Report proper errno when syscall falls.
10815 (Finsert_file_contents): Save and restore errno,
10816 so that report_file_error outputs the correct diagnostic.
10817 (Fwrite_region) [CLASH_DETECTION]: Likewise.
10819 2011-09-18 Eli Zaretskii <eliz@gnu.org>
10821 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
10823 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10825 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
10826 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
10828 2011-09-17 Eli Zaretskii <eliz@gnu.org>
10830 * xdisp.c (reseat_at_next_visible_line_start): Keep information
10831 about the current paragraph and restore it after the call to reseat.
10833 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
10834 (bidi_find_paragraph_start): Search back for paragraph beginning
10835 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
10836 (bidi_move_to_visually_next): Only trigger paragraph-related
10837 computations when the last character is a newline or at EOB, not
10838 just any NEUTRAL_B. (Bug#9470)
10840 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
10841 truncated lines if point is covered by a display string. (Bug#9524)
10843 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
10845 * xselect.c: Relax test for outgoing X longs (Bug#9498).
10846 (cons_to_x_long): New function.
10847 (lisp_data_to_selection_data): Use it. Correct the test for
10848 short-versus-long data; it was negated. Break out of vector
10849 loop, for efficiency, when a long datum is discovered.
10851 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
10853 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
10855 2011-09-16 Eli Zaretskii <eliz@gnu.org>
10857 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
10858 GCC PR/17406) by declaring this function with external scope.
10860 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10862 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
10863 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
10865 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
10867 * editfns.c (Fformat): Correctly handle text properties on "%%".

10877 of TAB characters in a composition.
10879 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
10881 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
10882 This occurs when processing a multibyte format.
10883 Problem reported by Wolfgang Jenker.
10885 2011-09-15 Johan Bockgård <bojohan@gnu.org>
10887 * xdisp.c (try_cursor_movement): Only check for exact match if
10888 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
10890 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10892 Remove unused external symbols.
10893 * dispextern.h (calc_pixel_width_or_height): Remove decl.
10894 * xdisp.c (calc_pixel_width_or_height): Now static.
10895 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
10896 * indent.c (check_display_width):
10897 * w32term.c: Fix comment to match code.
10898 * xterm.c, xterm.h (x_catching_errors): Remove.
10900 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
10902 * xselect.c: Use signed conversions more consistently (Bug#9498).
10903 (selection_data_to_lisp_data): Assume incoming selection data are
10904 signed integers, not unsigned. This is to be consistent with
10905 outgoing selection data, which was modified to use signed integers
10906 in as part of the fix to Bug#9196 in response to Jan D.'s comment
10907 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
10908 expects long, not unsigned long.
10910 2011-09-14 Eli Zaretskii <eliz@gnu.org>
10912 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
10913 computation of loop end. Reported by Johan Bockgård
10916 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
10918 * frame.c (Fother_visible_frames_p): Function deleted.
10920 2011-09-12 Eli Zaretskii <eliz@gnu.org>
10922 * indent.c (compute_motion): Process display vector front to back
10923 rather than the other way around. (Bug#2496)
10925 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
10927 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
10929 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
10931 * minibuf.c (Fread_from_minibuffer): Doc fix.
10933 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10935 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
10936 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
10938 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
10940 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
10941 value for non-existent files.
10943 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10945 * fileio.c (Finsert_file_contents): If the file cannot be opened,
10946 set its "size" to -1. This will set the modtime_size field of
10947 the corresponding buffer to -1, which is what
10948 verify-visited-file-modtime expects for files that do not exist.
10951 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
10953 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
10955 * lisp.h: ... from here. push_key_description is no longer
10956 defined in keyboard.c, so its declaration should not be in
10957 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
10958 logically belongs with push_key_description.
10960 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
10962 * buffer.h: Include <sys/types.h> instead of <time.h>.
10963 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
10964 Problem reported by Herbert J. Skuhra.
10966 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
10968 * xml.c (parse_region): Make the parsing work for
10969 non-comment-starting XML files again (bug#9144).
10971 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
10973 * image.c (gif_load): Fix calculation of bottom and right corner.
10976 2011-09-10 Eli Zaretskii <eliz@gnu.org>
10978 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
10979 redisplay in small windows.
10981 2011-09-09 Eli Zaretskii <eliz@gnu.org>
10983 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
10985 2011-09-08 Martin Rudalics <rudalics@gmx.at>
10987 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
10988 Operate on live windows only.
10990 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
10992 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
10994 2011-09-07 Eli Zaretskii <eliz@gnu.org>
10996 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
10997 only under bidi iteration.
10999 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
11001 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
11003 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11005 isnan: Fix porting problem to Solaris 10 with bundled gcc.
11006 Without this fix, the command to link temacs failed due to an
11007 undefined symbol __builtin_isnan. This is because
11008 /usr/include/iso/math_c99.h #defines isnan(x) to
11009 __builtin_isnan(x), but the bundled gcc, which identifies itself
11010 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
11012 * floatfns.c (isnan): #undef, and then #define to a clone of
11014 (Fisnan): Always define, since it's always available now.
11015 (syms_of_floatfns): Always define isnan at the Lisp level.
11017 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11019 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
11021 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11023 * fileio.c: Fix bugs with large file offsets (Bug#9428).
11024 The previous code assumed that file offsets (off_t values) fit in
11025 EMACS_INT variables, which is not true on typical 32-bit hosts.
11026 The code messed up by falsely reporting buffer overflow in cases
11027 such as (insert-file-contents "big" nil 1 2) into an empty buffer
11028 when "big" contains more than 2**29 bytes, even though this
11029 inserts just one byte and does not overflow the buffer.
11030 (Finsert_file_contents): Store file offsets as off_t
11031 values, not as EMACS_INT values. Check for overflow when
11032 converting between EMACS_INT and off_t. When checking for
11033 buffer overflow or for overlap, take the offsets into account.
11034 Don't use EMACS_INT for small values where int suffices.
11035 When checking for overlap, fix a typo: ZV was used where
11036 ZV_BYTE was intended.
11037 (Fwrite_region): Don't assume off_t fits into 'long'.
11038 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
11040 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
11042 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
11044 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
11046 sprintf-related integer and memory overflow issues (Bug#9412).
11048 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
11049 (esprintf, exprintf, evxprintf): New functions.
11050 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
11051 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
11052 (modify_event_symbol): Do not assume that the length of
11053 name_alist_or_stem is safe to alloca and fits in int.
11054 (Fexecute_extended_command): Likewise for function name and binding.
11055 (Frecursion_depth): Wrap around reliably on integer overflow.
11056 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
11057 since some callers pass EMACS_INT values.
11058 (Fsingle_key_description): Don't crash if symbol name contains more
11059 than MAX_ALLOCA bytes.
11060 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
11061 (get_minibuffer): Arg is now EMACS_INT, not int.
11062 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
11063 (esprintf, exprintf, evxprintf): New decls.
11064 * window.h (command_loop_level, minibuf_level): Reflect API changes.
11066 * dbusbind.c (signature_cat): New function.
11067 (xd_signature, Fdbus_register_signal):
11068 Do not overrun buffer; instead, report string overflow.
11070 * dispnew.c (add_window_display_history): Don't overrun buffer.
11071 Truncate instead; this is OK since it's just a log.
11073 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
11074 even if the time zone offset is outlandishly large.
11075 Don't mishandle offset == INT_MIN.
11077 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
11078 when creating daemon; the previous buffer-overflow check was incorrect.
11080 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
11081 which has the guts of the old verror function.
11083 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
11084 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
11086 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
11087 (font_unparse_xlfd): Don't blindly alloca long strings.
11088 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
11089 fits in int, when using sprintf. Use single snprintf to count
11090 length of string rather than counting it via multiple sprintfs;
11091 that's simpler and more reliable.
11092 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
11093 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
11094 sprintf, in case result does not fit in int.
11096 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
11097 (fontset_from_font): Print it.
11099 * frame.c (tty_frame_count): Now printmax_t, not int.
11100 (make_terminal_frame, set_term_frame_name): Print it.
11101 (x_report_frame_params): In X, window IDs are unsigned long,
11102 not signed long, so print them as unsigned.
11103 (validate_x_resource_name): Check for implausibly long names,
11104 and don't assume name length fits in 'int'.
11105 (x_get_resource_string): Don't blindly alloca invocation name;
11106 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
11109 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
11110 (xg_check_special_colors, xg_set_geometry):
11111 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
11113 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
11114 Use esprintf, not sprintf, in case result does not fit in int.
11116 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11117 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
11118 it as a large positive number.
11119 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
11120 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
11122 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
11123 in case result does not fit in int.
11125 * print.c (float_to_string): Detect width overflow more reliably.
11126 (print_object): Make sprintf buffer a bit bigger, to avoid potential
11127 buffer overrun. Don't assume list length fits in 'int'. Treat
11128 print length of 0 as 0, not as infinity; to be consistent with other
11129 uses of print length in this function. Don't overflow print length
11130 index. Don't assume hash table size fits in 'long', or that
11131 vectorlike size fits in 'unsigned long'.
11133 * process.c (make_process): Use printmax_t, not int, to format
11134 process-name gensyms.
11136 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
11138 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
11139 to avoid potential buffer overrun.
11141 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
11142 if X resource line is longer than 512 bytes.
11144 * xfns.c (x_window): Make sprintf buffer a bit bigger
11145 to avoid potential buffer overrun.
11147 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
11149 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
11151 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
11153 Integer overflow fixes for scrolling, etc.
11154 Without these, Emacs silently mishandles large integers sometimes.
11155 For example, "C-u 4294967297 M-x recenter" was treated as if
11156 it were "C-u 1 M-x recenter" on a typical 64-bit host.
11158 * xdisp.c (try_window_id): Check Emacs fixnum range before
11159 converting to 'int'.
11161 * window.c (window_scroll_line_based, Frecenter):
11162 Check that an Emacs fixnum is in range before assigning it to 'int'.
11163 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
11164 values converted from Emacs fixnums.
11165 (Frecenter): Don't wrap around a line count if it is out of 'int'
11166 range; instead, treat it as an extreme value.
11167 (Fset_window_configuration, compare_window_configurations):
11168 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
11170 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
11171 that can exceed INT_MAX. Check that EMACS_INT value is in range
11172 before assigning it to the (possibly-narrower) index.
11173 (match_limit): Don't assume that a fixnum can fit in 'int'.
11175 * print.c (print_object): Use ptrdiff_t, not int, for index that can
11178 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
11179 (Fvertical_motion): Don't wrap around LINES values that don't fit
11180 in 'int'. Instead, treat them as extreme values. This is good
11181 enough for windows, which can't have more than INT_MAX lines anyway.
11183 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
11185 * Require libxml/parser.h to avoid compilation warning.
11187 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
11189 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
11190 since this reportedly can destroy thread storage.
11192 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
11194 * syntax.c (find_defun_start): Update all cache variables if
11195 exiting early (Bug#9401).
11197 2011-08-30 Eli Zaretskii <eliz@gnu.org>
11199 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
11201 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
11202 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
11203 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
11205 * term.c (tty_append_glyph): New function.
11206 (produce_stretch_glyph): Static function and its prototype deleted.
11208 * dispextern.h (produce_stretch_glyph, tty_append_glyph):

11213 * image.c (parse_image_spec): Check for nonnegative, not for positive,
11214 when checking :margin (Bug#9390).
11215 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
11216 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
11217 so that the name doesn't mislead. All uses changed.
11219 2011-08-28 Johan Bockgård <bojohan@gnu.org>
11221 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
11224 2011-08-27 Eli Zaretskii <eliz@gnu.org>

11227 position beyond to_charpos, if we are scanning backwards.
11228 (move_it_vertically_backward): When DY == 0, make sure we get to
11229 the first character in the line after the newline.
11231 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
11233 * ccl.c: Improve and simplify overflow checking (Bug#9196).
11234 (ccl_driver): Do not generate an out-of-range pointer.
11235 (Fccl_execute_on_string): Remove unnecessary check for
11236 integer overflow, noted by Stefan Monnier in
11237 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
11238 Remove a FIXME that didn't need fixing.
11239 Simplify the newly-introduced buffer reallocation code.
11241 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
11243 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
11245 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
11247 Integer and memory overflow issues (Bug#9196).
11249 * doc.c (get_doc_string): Rework so that
11250 get_doc_string_buffer_size is the actual buffer size, rather than
11251 being 1 less than the actual buffer size; this makes xpalloc more
11254 * image.c (x_allocate_bitmap_record, cache_image):
11255 * xselect.c (Fx_register_dnd_atom):
11256 Simplify previous changes by using xpalloc.
11258 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
11259 since either will do and ptrdiff_t is convenient with xpalloc.
11261 * charset.c (charset_table_size)
11262 (struct charset_sort_data.priority): Now ptrdiff_t.
11263 (charset_compare): Don't overflow if priorities differ greatly.
11264 (Fsort_charsets): Don't assume list length fits in int.
11265 Check for size-calculation overflow when allocating sort data.
11266 (syms_of_charset): Allocate an initial charset table that is
11267 just under 64 KiB, to avoid problems with glibc malloc and mmap.
11269 * cmds.c (internal_self_insert): Check for size-calculation overflow.
11271 * composite.h (struct composition.glyph_len): Now int, not unsigned.
11272 The actual value is always <= INT_MAX, and leaving it unsigned made
11273 overflow checking harder.
11275 * dispextern.h (struct glyph_matrix.rows_allocated)
11276 (struct face_cache.size): Now ptrdiff_t, for convenience in use
11277 with xpalloc. The values are still always <= INT_MAX.
11279 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
11281 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
11282 (SAFE_NALLOCA): New macro.

11285 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
11286 (set_cache_region, invalidate_region_cache)
11287 (revalidate_region_cache, know_region_cache, region_cache_forward)
11288 (region_cache_backward, pp_cache):
11289 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
11290 so that ptrdiff_t * can be passed to xpalloc.
11291 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
11292 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
11293 (pp_cache): Don't assume cache_len fits in int.
11294 * region-cache.h: Adjust extern decls to match.
11296 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
11297 EMACS_INT, since either will do, for xpalloc.
11299 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
11300 (xnmalloc, xnrealloc, xpalloc): New functions.
11302 * bidi.c (bidi_shelve_header_size): New constant.
11303 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
11304 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
11306 * bidi.c (bidi_cache_shrink):
11307 * buffer.c (overlays_at, overlays_in, record_overlay_string)
11309 Don't update size of array until after memory allocation succeeds,
11310 because xmalloc/xrealloc may not return.
11311 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
11312 now that we have proper integer overflow checking.
11313 (record_overlay_string, overlay_strings): Catch overflows when
11314 calculating size of overlay_str_buf.
11316 * callproc.c (Fcall_process): Check for size overflow when
11317 calculating size of args2.
11318 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
11319 Normally we prefer signed values, but sticking with ptrdiff_t would
11320 require adding more-complicated checks.
11322 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
11323 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
11324 Redo buffer-overflow calculations to avoid integer overflow.
11325 Add a FIXME comment where memory seems to be over-allocated.
11327 * character.c (Fstring): Check for size-calculation overflow.
11329 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
11330 unnecessary integer overflow. Check for size overflow.
11331 (encode_coding_object): Don't update size until xmalloc succeeds.
11333 * composite.c (get_composition_id): Check for overflow in glyph
11334 length calculations.
11336 Integer and memory overflow fixes for display code.
11337 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
11338 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)

11351 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
11352 (get_doc_string): Check for size calculation overflow.
11353 Don't update size until allocation succeeds.
11354 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
11355 EMACS_INT, where ptrdiff_t will do.
11356 (Fsubstitute_command_keys): Check for string overflow.
11358 * editfns.c (set_time_zone_rule): Don't assume environment length
11360 (message_length): Now ptrdiff_t, not int.
11361 (Fmessage_box): Don't update size until allocation succeeds.
11362 Don't assume message length fits in int.
11363 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
11365 * emacs.c (main): Do not reallocate argv, since there is a null at
11366 the end that can be overwritten, and this way there's no need to
11367 worry about size-calculation overflow.
11368 (sort_args): Check for size-calculation overflow.
11370 * eval.c (init_eval_once, grow_specpdl): Don't update size until
11372 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
11374 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
11375 (x_set_scroll_bar_width, x_figure_window_size):
11376 Check for integer overflow.
11377 (x_set_alpha): Do not assume XINT fits in int.
11379 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
11380 This is for the members text_lines, text_cols, total_lines, total_cols,
11381 where the system imposes an 'int' limit.
11383 * fringe.c (Fdefine_fringe_bitmap):
11384 Don't update size until alloc works.
11386 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
11387 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
11389 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
11390 Check for size-calculation overflow.
11391 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
11392 do, as we prefer signed integers.
11393 (id_to_widget.max_size, id_to_widget.used)
11394 (xg_store_widget_in_map, xg_remove_widget_from_map)
11395 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
11396 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
11397 Use and return ptrdiff_t, not int.
11398 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
11399 * gtkutil.h: Change prototypes to match the above.
11401 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
11402 are duplicate now that they've been promoted to lisp.h.
11403 (x_allocate_bitmap_record, x_alloc_image_color)
11404 (make_image_cache, cache_image, xpm_load):

11416 Use ptrdiff_t, not int, to count maps.
11417 (read_char_minibuf_menu_prompt): Check for overflow in size
11418 calculations. Don't update size until allocation succeeds.
11419 Redo calculations to avoid overflow.

11448 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
11449 for command line length. Do not attempt to address one before the
11450 beginning of an array, as that's not portable.
11452 * term.c (max_frame_lines): Remove; unused.
11453 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
11455 (encode_terminal_code, calculate_costs): Check for size

11462 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
11463 subtracting pointers.

11478 Use ptrdiff_t, not int, for sizes.
11479 (Finternal_make_lisp_face, cache_face):
11480 Check for size calculation overflow.
11481 (cache_face): Treat size calculation overflows as if they were
11482 memory exhaustion (the usual treatment), rather than aborting.
11484 * xfns.c (x_encode_text, x_set_name_internal)
11485 (Fx_change_window_property): Use ptrdiff_t, not int, to count
11486 sizes, since they can exceed INT_MAX in size. Check for size

11490 (xg_select): Check for size calculation overflow.
11491 Don't update size until alloc done.
11493 * xrdb.c (get_environ_db): Don't assume path length fits in int,
11494 as sprintf is limited to int lengths.
11496 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
11497 (X_LONG_MIN): New macros.
11498 Use them to make the following changes clearer.
11499 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
11500 This change doesn't affect the value now, but it may help remind
11501 future maintainers not to raise the value too much later.
11502 (SELECTION_QUANTUM): Remove, replacing with ...
11503 (selection_quantum): ... new function, which avoids overflow.
11505 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
11506 assumption that selection length fits in 'int'.

11519 (lisp_data_to_selection_data, x_property_data_to_lisp):

11523 Don't store size until memory allocation succeeds.
11524 (x_get_window_property): Plug memory leak on memory exhaustion.
11525 Don't double-block input; malloc is safe here. Don't assume 2**34
11526 - 4 fits in unsigned long. Add an xassert to check
11527 XGetWindowProperty overflow. Be more careful about overflow
11528 calculations, and distinguish size from memory overflow better.

11530 unsigned int is less than INT_MAX.
11531 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

11533 (lisp_data_to_selection_data): Don't assume that integers
11534 in the range -65535 through -1 fit in an X unsigned short.
11535 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
11536 result parameters unless successful. Rely on cons_to_unsigned
11537 to report problems with elements; the old code wasn't right anyway.
11538 (x_check_property_data): Check for int overflow; we cannot use
11539 a wider type due to X limits.
11540 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

11572 * lisp.h (hash_lookup, hash_put):
11573 * minibuf.c (Ftest_completion):
11574 Use ptrdiff_t for hash table indexes, not int (which is too
11575 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
11576 32-bit --with-wide-int hosts).
11578 * charset.c (Fdefine_charset_internal): Check for integer overflow.
11579 Add a FIXME comment about memory leaks.
11580 (syms_of_charset): Don't assume xmalloc returns.

11587 with outlandish widths.
11588 * character.h (sanitize_tab_width): Rename from sanitize_width,
11589 now that we have two such functions. All uses changed.

11610 exceed limits imposed by XClientMessageEvent, as well as the usual
11611 ptrdiff_t and size_t limits.
11613 * keyboard.c: Overflow, signedness and related fixes.
11614 (make_lispy_movement): Use same integer type in forward decl
11615 that is used in the definition.
11616 (read_key_sequence, keyremap_step):
11617 Change bufsize argument back to int, undoing my 2011-03-30 change.
11618 We prefer signed types, and int is wide enough here.
11619 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
11620 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
11621 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
11622 length, not size_t. Use ptrdiff_t for index, not int.
11623 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
11624 possibility of integer overflow.
11626 Overflow, signedness and related fixes for images.

11652 Prefer int to unsigned where either will do.
11653 (tiff_handler): New function, combining the cores of the
11654 old tiff_error_handler and tiff_warning_handler.
11655 This function is rewritten to use vsnprintf and thereby avoid
11656 stack buffer overflows. It uses only the features of vsnprintf
11657 that are common to both POSIX and native Microsoft.
11658 (tiff_error_handler, tiff_warning_handler): Use it.
11659 (tiff_load, gif_load, imagemagick_load_image):
11660 Don't assume :index value fits in 'int'.

11663 the integer types that MagickCropImage accepts. Don't assume
11664 Vimagemagick_render_type has a nonnegative value. Don't assume
11665 size_t fits in 'long'.
11666 (gs_load): Use printmax_t to print the widest integers possible.

11680 (handle_single_display_spec): If the display spec is of the form
11681 `(space ...)', and specifies display in the text area, return 2
11683 (try_cursor_movement): Check for the need to scroll more
11684 accurately, and prefer exact match for point under bidi.
11685 Don't advance `row' beyond the last row of the window.

11703 buffers, return left-to-right.
11704 (set_cursor_from_row): Consider candidate row a win if its glyph
11705 represents a newline and point is on that newline. Fixes cursor
11706 positioning on the newline at EOL of R2L text within L2R
11707 paragraph, and vice versa.
11708 (try_cursor_movement): Check continued rows, in addition to
11709 continuation rows. Fixes unwarranted scroll when point enters a
11710 continued line of R2L text within an L2R paragraph, or vice versa.

11738 * xdisp.c (redisplay_window): When computing centering_position,
11739 account for the height of the header line. (Bug#8874)
11741 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
11742 instead of CHAR_TO_BYTE. Fixes a crash when a completion
11743 candidate is selected by the mouse, and that candidate has a
11744 composed character under the mouse.
11746 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
11747 coordinates reported by pos-visible-in-window-p for a composed
11748 character in column zero.

11757 consider it a hit if to_charpos is anywhere in the range of the
11758 composed buffer positions.
11760 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
11762 * image.c (gif_load): Don't assume that each subimage has the same
11763 dimensions as the base image. Handle disposal method that is
11764 "undefined" by the gif spec (Bug#9335).

11774 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
11775 from an Org mode buffer to a Speedbar frame.
11777 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
11778 a composition, take its buffer position from IT->cmp_it.charpos.
11779 Fixes cursor positioning at the beginning of a line that begins
11780 with a composed character.
11782 2011-08-18 Eli Zaretskii <eliz@gnu.org>
11784 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
11785 character bidirectional type, use STRONG_L instead. Fixes crashes
11786 in a buffer produced by `describe-categories'.
11788 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
11789 members before the level stack, so they would be saved and
11790 restored when copying iterator state. Fixes incorrect reordering
11791 around TABs covered by display properties.

11927 the iterator structure wrt the object coming from a display
11928 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
11929 properties. (Bug#9284)

12102 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
12104 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
12105 setting frame foreground color (Bug#9175).
12106 (x_set_background_color): Likewise.
12108 * nsmenu.m (-setText): Size tooltip dimensions precisely to
12109 contents (Bug#9176).
12110 (EmacsTooltip -init): Remove bezels and add shadows to
12113 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
12114 or scroll bar (Bug#8470).
12116 * nsfont.m (nsfont_open): Remove assignment to voffset and
12117 unnecessary vars hshink, expand, hd, full_height, min_height.
12118 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
12120 * nsterm.h (nsfont_info): Remove voffset field.
12122 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
12124 Implement strike-through and overline on NextStep (Bug#8863).
12126 * nsfont.m (nsfont_open): Use underline position provided by font,
12127 instead of hard-coded value of 2.
12128 (nsfont_draw): Call ns_draw_text_decoration instead.
12130 * nsterm.h: Add declaration for ns_draw_text_decoration.
12132 * nsterm.m (ns_draw_text_decoration): New function for drawing
12133 underline, overline, and strike-through.
12134 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
12135 ns_draw_text_decoration. Change treatment of cursor drawing to
12136 accommodate underlining, etc.
12138 2011-07-28 Eli Zaretskii <eliz@gnu.org>
12140 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
12143 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12145 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
12146 Without this fix, if a signal arrives just after memory fills up,
12147 'malloc' might be invoked reentrantly.
12149 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
12150 In other words, assume that every image size is allowed, on non-X
12151 hosts. This assumption is probably wrong, but it lets Emacs compile.
12153 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
12155 * regex.c (re_iswctype): Convert return values to boolean.
12157 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
12159 * xdisp.c (compute_display_string_pos): Don't use cached display
12160 string position if the buffer had its restriction changed.
12163 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12165 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12167 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
12169 Integer signedness and overflow and related fixes. (Bug#9079)
12171 * bidi.c: Integer size and overflow fixes.
12172 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
12173 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
12174 (bidi_cache_find_level_change, bidi_cache_ensure_space)
12175 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
12176 (bidi_find_other_level_edge):
12177 Use ptrdiff_t instead of EMACS_INT where either will do.
12178 This works better on 32-bit hosts configured --with-wide-int.
12179 (bidi_cache_ensure_space): Check for size-calculation overflow.
12180 Use % rather than repeated addition, for better worst-case speed.
12181 Don't set bidi_cache_size until after xrealloc returns, because it
12183 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
12184 (bidi_cache_ensure_space): Also check that the bidi cache size
12185 does not exceed that of the largest Lisp string or buffer. See Eli
12186 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
12188 * alloc.c (__malloc_size_t): Remove.
12189 All uses replaced by size_t. See Andreas Schwab's note
12190 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
12192 * image.c: Improve checking for integer overflow.
12193 (check_image_size): Assume that f is nonnull, since
12194 it is always nonnull in practice. This is one less thing to
12195 worry about when checking for integer overflow later.
12196 (x_check_image_size): New function, which checks for integer
12197 overflow issues inside X.
12198 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
12199 This removes the need for a memory_full check.
12200 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
12201 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
12202 (xbm_read_bitmap_data): Change locals back to 'int', since
12203 their values must fit in 'int'.
12204 (xpm_load_image, png_load, tiff_load):
12205 Invoke x_create_x_image_and_pixmap earlier,
12206 to avoid much needless work if the image is too large.
12207 (tiff_load): Treat overly large images as if
12208 x_create_x_image_and_pixmap failed, not as malloc failures.
12209 (gs_load): Use x_check_image_size.
12211 * gtkutil.c: Omit integer casts.
12212 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
12213 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
12215 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
12217 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
12218 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
12219 would wrongly return t on a 64-bit host.
12221 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
12222 The plain *_OVERFLOW macros run afoul of GCC bug 49705
12223 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
12224 and therefore cause GCC to emit a bogus diagnostic in some cases.
12226 * image.c: Integer signedness and overflow and related fixes.
12227 This is not an exhaustive set of fixes, but it's time to
12228 record what I've got.
12229 (lookup_pixel_color, check_image_size): Remove redundant decls.
12230 (check_image_size): Don't assume that arbitrary EMACS_INT values
12231 fit in 'int', or that arbitrary 'double' values fit in 'int'.
12232 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
12233 (tiff_load, imagemagick_load_image):
12234 Check for overflow in size calculations.
12235 (x_create_x_image_and_pixmap): Remove unnecessary test for
12236 xmalloc returning NULL; that can't happen.
12237 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
12238 (xpm_color_bucket): Use better integer hashing function.
12239 (xpm_cache_color): Don't possibly over-allocate memory.
12240 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
12241 (gif_memory_source):
12242 Use ptrdiff_t, not int or size_t, to record sizes.
12243 (png_load): Don't assume values greater than 2**31 fit in 'int'.
12244 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
12245 either works, as we prefer signed integers.
12246 (tiff_read_from_memory, tiff_write_from_memory):
12247 Return tsize_t, not size_t, since that's what the TIFF API wants.
12248 (tiff_read_from_memory): Don't fail simply because the read would
12249 go past EOF; instead, return a short read.
12250 (tiff_load): Omit no-longer-needed casts.
12251 (Fimagemagick_types): Don't assume size fits into 'int'.
12253 Improve hashing quality when configured --with-wide-int.
12254 * fns.c (hash_string): New function, taken from sxhash_string.
12255 Do not discard information about ASCII character case; this
12256 discarding is no longer needed.
12257 (sxhash-string): Use it. Change sig to match it. Caller changed.
12258 * lisp.h: Declare it.
12259 * lread.c (hash_string): Remove, since we now use fns.c's version.
12260 The fns.c version returns a wider integer if --with-wide-int is
12261 specified, so this should help the quality of the hashing a bit.
12263 * emacs.c: Integer overflow minor fix.
12264 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
12265 Define only if GNU_LINUX.
12266 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
12268 * dispnew.c: Integer signedness and overflow fixes.
12269 Remove unnecessary forward decls, that were a maintenance hassle.
12270 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
12272 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
12273 (scrolling_window): Use ptrdiff_t, not int, for byte count.
12274 (prepare_desired_row, line_draw_cost):
12275 Use int, not unsigned, where either works.
12276 (save_current_matrix, restore_current_matrix):
12277 Use ptrdiff_t, not size_t, where either works.
12278 (init_display): Check for overflow more accurately, and without
12279 relying on undefined behavior.
12281 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
12282 Remove, replacing with the new symbols in lisp.h. All uses changed.
12283 * fileio.c (make_temp_name):
12284 * filelock.c (lock_file_1, lock_file):
12285 * xdisp.c (message_dolog):
12286 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
12287 Use pMd etc. instead.
12288 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
12289 replacing the pWIDE etc. symbols removed from editfns.c.
12291 * keyboard.h (num_input_events): Now uintmax_t.
12292 This is (very slightly) less likely to mess up due to wraparound.
12295 * buffer.c: Integer signedness fixes.
12296 (alloc_buffer_text, enlarge_buffer_text):
12297 Use ptrdiff_t rather than size_t when either will do, as we prefer
12300 * alloc.c: Integer signedness and overflow fixes.
12301 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
12302 (__malloc_size_t): Default to size_t, not to int.
12303 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
12304 (Fgarbage_collect, mark_object_loop_halt, mark_object):
12305 Prefer ptrdiff_t to size_t when either would do, as we prefer
12307 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
12308 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
12309 Now const. Initialize with values that are in range even if char
12311 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
12312 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
12313 These functions do the right thing with sizes > 2**32.
12314 (check_depth): Now ptrdiff_t, not int.
12315 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
12316 Adjust to new way of storing sizes. Check for size overflow bugs
12318 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
12319 slightly wrong anyway, as it missed one instance of
12320 XMALLOC_OVERRUN_CHECK_OVERHEAD.
12321 (refill_memory_reserve): Omit needless cast to size_t.
12322 (mark_object_loop_halt): Mark as externally visible.
12324 * xselect.c: Integer signedness and overflow fixes.
12325 (Fx_register_dnd_atom, x_handle_dnd_message):
12326 Use ptrdiff_t, not size_t, since we prefer signed.
12327 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
12328 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
12329 x_dnd_atoms_size and x_dnd_atoms_length.
12331 * doprnt.c: Prefer signed to unsigned when either works.
12333 * doprnt.c (doprnt):
12335 * xdisp.c (vmessage):
12336 Use ptrdiff_t, not size_t, when using or implementing doprnt,
12337 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
12338 prefer signed arithmetic to avoid comparison confusion.
12339 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
12340 but is a bit tricky.
12342 Assume freestanding C89 headers, string.h, stdlib.h.
12343 * data.c, doprnt.c, floatfns.c, print.c:
12344 Include float.h unconditionally.
12345 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
12346 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
12347 * regex.c: Likewise for stddef.h, string.h.
12348 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
12349 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
12350 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
12351 (STDC_HEADERS): Remove obsolete defines.
12352 * sysdep.c: Include limits.h unconditionally.
12354 Assume support for memcmp, memcpy, memmove, memset.
12355 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
12356 * regex.c (memcmp, memcpy):
12357 Remove; we assume C89 now.
12359 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
12360 (__malloc_safe_bcopy): Remove; no longer needed.
12362 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
12363 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
12364 well either way, and we prefer signed to unsigned.
12366 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
12368 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
12369 closes the connection while we're reading (bug#9182).
12371 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
12373 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
12374 are specified (Bug#9168).
12376 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
12378 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
12379 Found by GCC static checking and --with-wide-int on a 32-bit host.
12381 2011-07-25 Eli Zaretskii <eliz@gnu.org>
12383 * xdisp.c (compute_display_string_pos): Fix logic of caching
12384 previous display string position. Initialize cached_prev_pos to
12385 -1. Fixes slow-down at the beginning of a buffer.
12387 2011-07-24 Eli Zaretskii <eliz@gnu.org>
12389 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
12390 for attrs[LFACE_FONTSET_INDEX].
12392 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
12394 * xml.c (parse_region): Remove unused local
12395 that was recently introduced.
12397 2011-07-23 Eli Zaretskii <eliz@gnu.org>
12399 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
12400 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
12402 * xdisp.c (move_it_in_display_line_to): Record the best matching
12403 position for TO_CHARPOS while scanning the line, and restore it on
12404 exit if none of the characters scanned was an exact match.
12405 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
12406 when exact match is impossible due to invisible text, and the
12407 lines are truncated.
12409 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
12411 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
12414 2011-07-22 Eli Zaretskii <eliz@gnu.org>
12416 Fix a significant slow-down of cursor motion with C-n, C-p,
12417 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
12418 auto-repeat under bidi redisplay in fontified buffers.
12419 * xdisp.c (compute_stop_pos_backwards): New function.
12420 (next_element_from_buffer): Call compute_stop_pos_backwards to
12421 find a suitable prev_stop when we find ourselves before
12423 (reseat): Don't look for prev_stop, as that could mean a very long
12425 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
12426 <cached_disp_overlay_modiff>: Cache for last found display string
12428 (compute_display_string_pos): Return the cached position if asked
12429 about the same buffer in the same area of character positions, and
12430 the buffer wasn't changed since the time the display string
12431 position was cached.
12433 2011-07-22 Eli Zaretskii <eliz@gnu.org>
12435 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
12436 is an integer, which is important for empty lines. (Bug#9149)
12438 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
12440 * frame.c (Fmodify_frame_parameters): In tty case, update the
12441 default face if necessary (Bug#4238).
12443 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
12445 * editfns.c (Fstring_to_char): No need to explain what a character
12446 is in the docstring (Bug#6576).
12448 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
12450 * xml.c (parse_region): Make sure we always return a tree.
12452 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
12454 * xml.c (parse_region): If a document contains only comments,
12457 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
12459 * xml.c (make_dom): Return comments, too.
12461 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
12464 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
12465 and the surrounding thread.
12466 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
12467 rather than fgets, and retry after EINTR. Otherwise, 'emacs
12468 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
12470 * s/openbsd.h (BROKEN_SIGIO): Define.
12471 * unexelf.c (unexec) [__OpenBSD__]:
12472 Don't update the .mdebug section of the Alpha COFF symbol table.
12474 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12476 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
12479 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
12481 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
12482 This fixes some race conditions on the permissions of any newly
12485 * alloc.c (valid_pointer_p): Use pipe, not open.
12486 This fixes some permissions issues when debugging.
12488 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
12489 If fchown fails to set both uid and gid, try to set just gid,
12490 as that is sometimes allowed. Adjust the file's mode to eliminate
12491 setuid or setgid bits that are inappropriate if fchown fails.
12493 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
12495 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
12496 to compare Lisp_Objects.
12497 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
12498 global_gnutls_log_level, don't mistake it for a Lisp_Object.
12499 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
12501 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
12503 * lread.c (read_integer): Unread even EOF character.
12504 (read1): Likewise. Properly record start position of symbol.
12506 * lread.c (read1): Read `#:' as empty uninterned symbol if no
12507 symbol character follows.
12509 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
12511 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
12512 This works around a problem with the previous change to Fcopy_file.
12513 Recent glibc declares fchown with __attribute__((warn_unused_result)),
12514 and without this change, GCC might complain about discarding
12515 fchown's return value.
12517 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
12519 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
12521 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
12523 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
12525 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
12527 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
12528 it's used from the C level.
12530 * process.c: Use the same condition for POLL_FOR_INPUT in both
12531 keyboard.c and process.c (bug#1858).
12533 2011-07-09 Lawrence Mitchell <wence@gmx.li>
12535 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
12536 (Fgnutls_boot): Use it.
12538 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
12540 * doc.c (Fsubstitute_command_keys): Revert last change.
12542 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
12544 * doc.c (Fsubstitute_command_keys): Clarify that \= really only

12613 the iterator is before prev_stop.

13095 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

13132 Random fixes. E.g., (random) never returned negative values.
13133 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
13134 subseconds part to the entropy, as that's a bit more random.
13135 Prefer signed to unsigned, since the signedness doesn't matter and
13136 in general we prefer signed. When given a limit, use a
13137 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
13138 latter isn't right if USE_2_TAGS_FOR_INTS.
13139 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
13140 not 0..VALMASK. Don't discard "excess" bits that random () returns.

13152 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
13153 This is more efficient than Ffile_directory_p and avoids a minor race.

13157 * buffer.c (Foverlay_put): Say what the return value is
13160 * fileio.c (barf_or_query_if_file_exists): Check first if the file

13164 error be more correct.
13166 * fns.c (Frequire): Remove the mention of the .gz files, since

13180 Qgnutls_bootprop_verify_error (which is no longer used).
13182 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
13183 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
13184 Also (re)move comments that are misplaced or no longer relevant.

13285 * eval.c (struct backtrace): Simplify and port the data structure.
13286 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
13287 signed bit field, as this assumption is not portable and it makes
13288 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
13289 "char debug_on_exit : 1" as this is not portable either; instead,
13290 use the portable "unsigned int debug_on_exit : 1". Remove unused
13291 member evalargs. Remove obsolete comments about cc bombing out.
13293 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

13453 * gnutls.c (syms_of_gnutls): Use the DEFSYM macro from character.h.
13455 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
13457 Integer and buffer overflow fixes (Bug#8873).
13459 * print.c (printchar, strout): Check for string overflow.
13460 (PRINTPREPARE, printchar, strout):
13461 Don't set size unless allocation succeeds.
13463 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
13464 for sizes. Check for string overflow more accurately.
13465 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
13467 * macros.c: Integer and buffer overflow fixes.
13468 * keyboard.h (struct keyboard.kbd_macro_bufsize):
13469 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
13470 Use ptrdiff_t, not int, for sizes.
13471 Don't increment bufsize until after realloc succeeds.
13472 Check for size-calculation overflow.
13473 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
13475 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
13477 * lread.c: Integer overflow fixes.
13478 (read_integer): Radix is now EMACS_INT, not int,
13479 to improve quality of diagnostics for out-of-range radices.
13480 Calculate buffer size correctly for out-of-range radices.
13481 (read1): Check for integer overflow in radices, and in
13482 read-circle numbers.
13483 (read_escape): Avoid int overflow.
13484 (Fload, openp, read_buffer_size, read1)
13485 (substitute_object_recurse, read_vector, read_list, map_obarray):
13486 Use ptrdiff_t, not int, for sizes.
13487 (read1): Use EMACS_INT, not int, for sizes.
13488 Check for size overflow.
13490 * image.c (cache_image): Check for size arithmetic overflow.
13492 * lread.c: Integer overflow issues.
13493 (saved_doc_string_size, saved_doc_string_length)
13494 (prev_saved_doc_string_size, prev_saved_doc_string_length):
13495 Now ptrdiff_t, not int.
13496 (read1): Don't assume doc string length fits in int. Check for
13497 out-of-range doc string lengths.
13498 (read_list): Don't assume file position fits in int.
13499 (read_escape): Check for hex character overflow.
13501 2011-06-22 Leo Liu <sdl.web@gmail.com>
13503 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
13504 Move to minibuffer.el.
13506 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
13508 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
13509 The following patches are for when GLYPH_DEBUG && !XASSERT.
13510 * dispextern.h (trace_redisplay_p, dump_glyph_string):
13511 * dispnew.c (flush_stdout):
13512 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
13513 Mark as externally visible.
13514 * dispnew.c (check_window_matrix_pointers): Now static.
13515 * dispnew.c (window_to_frame_vpos):
13516 * xfns.c (unwind_create_frame):
13517 * xterm.c (x_check_font): Remove unused local.
13518 * scroll.c (CHECK_BOUNDS):
13519 * xfaces.c (cache_fache): Rename local to avoid shadowing.
13520 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
13521 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
13522 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
13523 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
13525 (debug_method_add): Use va_list and vsprintf rather than relying
13526 on undefined behavior with wrong number of arguments.
13527 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
13528 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
13529 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
13530 since we're not interested in debugging glyphs with old libraries.
13531 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
13532 GCC 4.6.0's static checking.
13534 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
13536 Integer overflow and signedness fixes (Bug#8873).
13537 A few related buffer overrun fixes, too.

13543 (x_bitmap_mask, x_allocate_bitmap_record)
13544 (x_create_bitmap_from_data, x_create_bitmap_from_file)
13545 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
13546 (x_create_bitmap_from_xpm_data):
13547 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
13548 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
13550 * xfaces.c (load_pixmap):
13551 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
13552 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
13553 (.bitmaps_last, struct x_output.icon_bitmap):
13554 Use ptrdiff_t, not int, for bitmap indexes.
13555 (x_allocate_bitmap_record): Check for size overflow.
13556 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
13558 Use ptrdiff_t, not int, for overlay counts.
13559 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
13560 * editfns.c (overlays_around, get_pos_property):
13561 * textprop.c (get_char_property_and_overlay):
13562 * xdisp.c (next_overlay_change, note_mouse_highlight):
13563 * xfaces.c (face_at_buffer_position):
13564 * buffer.c (OVERLAY_COUNT_MAX): New macro.
13565 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
13566 (Fnext_overlay_change, Fprevious_overlay_change)
13567 (mouse_face_overlay_overlaps, Foverlays_in):
13568 Use ptrdiff_t, not int, for sizes.
13569 (overlays_at, overlays_in): Check for size-calculation overflow.
13571 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
13573 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
13574 (x_session_initialize): Do not assume string length fits in int.
13576 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
13577 This is unlikely, but can occur if DPI is outlandish.
13579 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
13580 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
13582 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
13583 * xrdb.c (magic_file_p, search_magic_path):
13584 Omit last arg SUFFIX; it was always 0. All callers changed.
13585 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
13587 * xfont.c (xfont_match): Avoid need for strlen.
13589 * xfns.c: Don't assume strlen fits in int.
13590 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
13592 * xdisp.c (message_log_check_duplicate): Return intmax_t,
13593 not unsigned long, as we prefer signed integers. All callers changed.
13594 Detect integer overflow in repeat count.
13595 (message_dolog): Don't assume print length fits in 39 bytes.
13596 (display_mode_element): Don't assume strlen fits in int.
13598 * termcap.c: Don't assume sizes fit in int and never overflow.
13599 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
13600 (gobble_line): Check for size-calculation overflow.
13602 * minibuf.c (Fread_buffer):
13603 * lread.c (intern, intern_c_string):
13604 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
13605 Don't assume string length fits in int.
13607 * keyboard.c (parse_tool_bar_item):
13608 * gtkutil.c (style_changed_cb): Avoid need for strlen.
13610 * font.c: Don't assume string length fits in int.
13611 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
13612 Use ptrdiff_t, not int.
13613 (font_intern_prop): Don't assume string length fits in int.
13614 Don't assume integer property fits in fixnum.
13615 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
13617 * filelock.c: Fix some buffer overrun and integer overflow issues.
13618 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
13619 Reformulate so as not to need the command string.
13620 Invoke gzip -cd rather than gunzip, as it's more portable.
13621 (lock_info_type, lock_file_1, lock_file):
13622 Don't assume pid_t and time_t fit in unsigned long.
13623 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
13624 (current_lock_owner): Prefer signed type for sizes.
13625 Use memcpy, not strncpy, where memcpy is what is really wanted.
13626 Don't assume (via atoi) that time_t and pid_t fit in int.
13627 Check for time_t and/or pid_t out of range, e.g., via a network share.
13628 Don't alloca where an auto var works fine.
13630 * fileio.c: Fix some integer overflow issues.
13631 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
13632 Don't assume string length fits in int.
13633 (directory_file_name): Don't assume string length fits in long.
13634 (make_temp_name): Don't assume pid fits in int, or that its print
13635 length is less than 20.
13637 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
13639 * coding.c (make_subsidiaries): Don't assume string length fits in int.
13641 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
13643 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
13644 We prefer signed integers, even for size calculations.
13646 * emacs.c: Don't assume string length fits in 'int'.
13647 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
13648 (main): Don't invoke strlen when not needed.
13650 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
13651 (XD_DEBUG_MESSAGE): Don't waste a byte.
13653 * callproc.c (getenv_internal_1, getenv_internal)
13654 (Fgetenv_internal):
13655 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
13657 * lread.c (invalid_syntax): Omit length argument.
13658 All uses changed. This doesn't fix a bug, but it simplifies the
13659 code away from its former Hollerith-constant appearance, and it's
13660 one less 'int' to worry about when looking at integer-overflow issues.
13661 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
13663 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
13664 This didn't break anything, but it didn't help either.
13665 It's confusing to put a bogus integer in a place where the actual
13666 value does not matter.
13667 (LIST_END_P): Remove unused macro and its bogus comment.
13668 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
13670 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
13671 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
13673 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
13674 We prefer signed types, and the value cannot exceed the EMACS_INT
13675 range anyway (because otherwise the length would not be representable).
13676 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
13677 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
13678 This avoids a GCC warning when WIDE_EMACS_INT.
13680 * indent.c (sane_tab_width): New function.
13681 (current_column, scan_for_column, Findent_to, position_indentation)
13682 (compute_motion): Use it. This is just for clarity.
13683 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
13685 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
13687 * lisp.h (lint_assume): New macro.
13688 * composite.c (composition_gstring_put_cache):
13689 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
13691 * editfns.c, insdel.c:
13692 Omit unnecessary forward decls, to simplify future changes.
13694 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
13696 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
13698 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
13699 Use much-faster test for byte-length change.
13700 Don't assume string byte-length fits in 'int'.
13701 Check that character arg fits in 'int'.
13702 (mapcar1): Declare byte as byte, for clarity.
13704 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
13706 * fns.c (concat): Catch string overflow earlier.
13707 Do not rely on integer wraparound.
13709 * dispextern.h (struct it.overlay_strings_charpos)
13710 (struct it.selective): Now EMACS_INT, not int.
13711 * xdisp.c (forward_to_next_line_start)
13712 (back_to_previous_visible_line_start)
13713 (reseat_at_next_visible_line_start, next_element_from_buffer):
13714 Don't arbitrarily truncate the value of 'selective' to int.
13716 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
13718 * composite.c: Don't truncate sizes to 'int'.
13719 (composition_gstring_p, composition_reseat_it)
13720 (composition_adjust_point): Use EMACS_INT, not int.
13721 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
13722 not EMACS_UINT, for indexes.
13724 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
13726 * buffer.c: Include <verify.h>.
13727 (struct sortvec.priority, struct sortstr.priority):
13728 Now EMACS_INT, not int.
13729 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
13730 (struct sortstr.size, record_overlay_string)
13731 (struct sortstrlist.size, struct sortlist.used):
13732 Don't truncate size to int.
13733 (record_overlay_string): Check for size-calculation overflow.
13734 (init_buffer_once): Check at compile-time, not run-time.
13736 2011-06-22 Jim Meyering <meyering@redhat.com>
13738 Don't leak an XBM-image-sized buffer
13739 * image.c (xbm_load): Free the image buffer after using it.
13741 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
13744 * composite.c (find_automatic_composition): Omit needless 'return 0;'
13745 that Sun C diagnosed.
13746 * fns.c (secure_hash): Fix pointer signedness issue.
13747 * intervals.c (static_offset_intervals): New function.
13748 (offset_intervals): Use it.
13750 2011-06-21 Leo Liu <sdl.web@gmail.com>
13753 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
13756 * fns.c (secure_hash): Rename from crypto_hash_function and change
13757 the first arg to accept symbols.
13758 (Fsecure_hash): New primitive.
13759 (syms_of_fns): New symbols.
13761 2011-06-20 Deniz Dogan <deniz@dogan.se>
13763 * process.c (Fset_process_buffer): Clarify return value in
13766 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
13768 * dispnew.c (add_window_display_history): Use BVAR.
13770 * xdisp.c (debug_method_add): Use BVAR.
13771 (check_window_end, dump_glyph_matrix, dump_glyph)
13772 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
13774 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
13777 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
13778 check till after the cache is created in init_frame_faces.
13780 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
13782 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
13784 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
13786 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
13787 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
13788 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
13790 Improve buffer-overflow checking (Bug#8873).
13791 * fileio.c (Finsert_file_contents):
13792 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
13793 Remove the old (too-loose) buffer overflow checks.
13794 They weren't needed, since make_gap checks for buffer overflow.
13795 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
13796 The old code merely checked for Emacs fixnum overflow, and relied
13797 on undefined (wraparound) behavior. The new code avoids undefined
13798 behavior, and also checks for ptrdiff_t and/or size_t overflow.
13800 * editfns.c (Finsert_char): Don't dump core with very negative counts.
13801 Tune. Don't use wider integers than needed. Don't use alloca.
13802 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
13804 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
13806 * insdel.c, lisp.h (buffer_overflow): New function.
13807 (insert_from_buffer_1, replace_range, replace_range_2):
13808 * insdel.c (make_gap_larger):
13809 * editfns.c (Finsert_char):
13810 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
13812 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
13814 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
13816 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
13818 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
13819 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
13821 * fileio.c: Don't assume EMACS_INT fits in off_t.
13822 (emacs_lseek): New static function.
13823 (Finsert_file_contents, Fwrite_region): Use it.
13824 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
13826 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
13828 * fns.c: Don't overflow int when computing a list length.
13829 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
13830 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
13831 truncation on 64-bit hosts. Check for QUIT every
13832 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
13833 faster and is responsive enough.
13834 (Flength): Report an error instead of overflowing an integer.
13835 (Fsafe_length): Return a float if the value is not representable
13836 as a fixnum. This shouldn't happen except in contrived situations.
13837 (Fnthcdr, Fsort): Don't assume list length fits in int.
13838 (Fcopy_sequence): Don't assume vector length fits in int.
13840 * alloc.c: Check that resized vectors' lengths fit in fixnums.
13841 (header_size, word_size): New constants.
13842 (allocate_vectorlike): Don't check size overflow here.
13843 (allocate_vector): Check it here instead, since this is the only
13844 caller of allocate_vectorlike that could cause overflow.
13845 Check that the new vector's length is representable as a fixnum.
13847 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
13848 The previous code was bogus. For example, next_almost_prime (32)
13849 returned 39, which is undesirable as it is a multiple of 3; and
13850 next_almost_prime (24) returned 25, which is a multiple of 5 so
13851 why was the code bothering to check for multiples of 7?
13853 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
13855 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
13857 Variadic C functions now count arguments with ptrdiff_t.
13858 This partly undoes my 2011-03-30 change, which replaced int with size_t.
13859 Back then I didn't know that the Emacs coding style prefers signed int.
13860 Also, in the meantime I found a few more instances where arguments
13861 were being counted with int, which may truncate counts on 64-bit
13862 machines, or EMACS_INT, which may be unnecessarily wide.
13863 * lisp.h (struct Lisp_Subr.function.aMANY)
13864 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
13865 Arg counts are now ptrdiff_t, not size_t.
13866 All variadic functions and their callers changed accordingly.
13867 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
13868 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
13869 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
13870 * callint.c (Fcall_interactively): Check arg count for overflow,
13871 to avoid potential buffer overrun. Use signed char, not 'int',
13872 for 'varies' array, so that we needn't bother to check its size
13873 calculation for overflow.
13874 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
13875 * eval.c (apply_lambda):
13876 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
13877 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
13878 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
13880 * callint.c (Fcall_interactively): Don't use index var as event count.
13882 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
13883 * mem-limits.h (SIZE): Remove; no longer used.
13885 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
13887 Remove unnecessary casts.
13888 * xterm.c (x_term_init):
13889 * xfns.c (x_set_border_pixel):
13890 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
13891 These aren't needed now that we assume ANSI C.
13893 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
13894 It's more likely to cause problems (due to unsigned overflow)
13897 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
13899 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
13901 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
13903 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
13905 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
13907 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
13909 GLYPH_CODE_FACE returns EMACS_INT, not int.
13910 * dispextern.h (merge_faces):
13911 * xfaces.c (merge_faces):
13912 * xdisp.c (get_next_display_element, next_element_from_display_vector):
13913 Don't assume EMACS_INT fits in int.
13915 * character.h (CHAR_VALID_P): Remove unused parameter.
13916 * fontset.c, lisp.h, xdisp.c: All uses changed.
13918 * editfns.c (Ftranslate_region_internal): Omit redundant test.
13920 * fns.c (concat): Minor tuning based on overflow analysis.
13921 This doesn't fix any bugs. Use int to hold character, instead
13922 of constantly refetching from Emacs object. Use XFASTINT, not
13923 XINT, for value known to be a character. Don't bother comparing
13924 a single byte to 0400, as it's always less.
13926 * floatfns.c (Fexpt):
13927 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
13929 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
13932 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
13934 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
13935 Without this fix, on a 64-bit host (aset S 0 4294967386) would
13936 incorrectly succeed when S was a string, because 4294967386 was
13937 truncated before it was used.
13939 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
13940 Otherwise, an out-of-range integer could cause undefined behavior
13943 * composite.c: Use int, not EMACS_INT, for characters.
13944 (fill_gstring_body, composition_compute_stop_pos): Use int, not
13945 EMACS_INT, for values that are known to be in character range.
13946 This doesn't fix any bugs but is the usual style inside Emacs and
13947 may generate better code on 32-bit machines.
13949 Make sure a 64-bit char is never passed to ENCODE_CHAR.
13950 This is for reasons similar to the recent CHAR_STRING fix.
13951 * charset.c (Fencode_char): Check that character arg is actually
13952 a character. Pass an int to ENCODE_CHAR.
13953 * charset.h (ENCODE_CHAR): Verify that the character argument is no
13954 wider than 'int', as a compile-time check to prevent future regressions
13957 * character.c (char_string): Remove unnecessary casts.
13959 Make sure a 64-bit char is never passed to CHAR_STRING.
13960 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
13961 by silently ignoring the top 32 bits, allowing some values
13962 that were far too large to be valid characters.
13963 * character.h: Include <verify.h>.
13964 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
13965 arguments are no wider than unsigned, as a compile-time check
13966 to prevent future regressions in this area.
13968 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
13969 (Fsubst_char_in_region):
13971 * xdisp.c (decode_mode_spec_coding):
13972 Adjust to CHAR_STRING's new requirement.
13973 * editfns.c (Finsert_char, Fsubst_char_in_region):
13974 * fns.c (concat): Check that character args are actually
13975 characters. Without this test, these functions did the wrong
13976 thing with wildly out-of-range values on 64-bit hosts.
13978 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
13979 These casts should not be needed on 32-bit hosts, either.
13980 * keyboard.c (read_char):
13981 * lread.c (Fload): Remove casts to unsigned.
13983 * lisp.h (UNSIGNED_CMP): New macro.
13984 This fixes comparison bugs on 64-bit hosts.
13985 (ASCII_CHAR_P): Use it.
13986 * casefiddle.c (casify_object):
13987 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
13988 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
13989 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
13990 * dispextern.h (FACE_FROM_ID):
13991 * keyboard.c (read_char): Use UNSIGNED_CMP.
13993 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
13994 not to EMACS_INT, to avoid GCC warning.
13996 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
13998 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
13999 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
14000 isn't needed on 32-bit machines.
14002 * buffer.c (Fgenerate_new_buffer_name):
14003 Use EMACS_INT for count, not int.
14004 (advance_to_char_boundary): Return EMACS_INT, not int.
14006 * data.c (Qcompiled_function): Now static.
14008 * window.c (window_body_lines): Now static.
14010 * image.c (gif_load): Rename local to avoid shadowing.
14012 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
14013 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
14014 * alloc.c (make_save_value): Integer argument is now of type
14015 ptrdiff_t, not int.
14016 (mark_object): Use ptrdiff_t, not int.
14017 * lisp.h (pD): New macro.
14018 * print.c (print_object): Use it.
14020 * alloc.c: Use EMACS_INT, not int, to count objects.
14021 (total_conses, total_markers, total_symbols, total_vector_size)
14022 (total_free_conses, total_free_markers, total_free_symbols)
14023 (total_free_floats, total_floats, total_free_intervals)
14024 (total_intervals, total_strings, total_free_strings):
14025 Now EMACS_INT, not int. All uses changed.
14026 (Fgarbage_collect): Compute overall total using a double, so that
14027 integer overflow is less likely to be a problem. Check for overflow
14028 when converting back to an integer.
14029 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
14030 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
14031 These were 'int' variables that could overflow on 64-bit hosts;
14032 they were never used, so remove them instead of repairing them.
14033 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
14034 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
14035 Previously, this ceilinged at INT_MAX, but that doesn't work on
14037 (allocate_pseudovector): Don't use EMACS_INT when int would do.
14039 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
14040 (allocate_vectorlike): Check for ptrdiff_t overflow.
14041 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
14042 when a (possibly-narrower) signed value would do just as well.
14043 We prefer using signed arithmetic, to avoid comparison confusion.
14045 * alloc.c: Catch some string size overflows that we were missing.
14046 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
14047 for convenience in STRING_BYTES_MAX.
14048 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
14049 The definition here is exact; the one in lisp.h was approximate.
14050 (allocate_string_data): Check for string overflow. This catches
14051 some instances we weren't catching before. Also, it catches
14052 size_t overflow on (unusual) hosts where SIZE_MAX <= min
14053 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
14054 and ptrdiff_t and EMACS_INT are both 64 bits.
14056 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
14057 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
14058 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
14060 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
14062 * alloc.c (Fmake_string): Check for out-of-range init.
14064 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
14066 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
14068 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
14070 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
14071 xg_get_default_scrollbar_width.
14073 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
14074 (int_gtk_range_get_value): Move to the scroll bar part of the file.
14075 (style_changed_cb): Call update_theme_scrollbar_width and call
14076 x_set_scroll_bar_default_width and xg_frame_set_char_size for
14077 all frames (Bug#8505).
14078 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
14079 Call gtk_window_set_resizable if HAVE_GTK3.
14080 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
14081 and height if HAVE_GTK3 (Bug#8505).
14082 (scroll_bar_width_for_theme): New variable.
14083 (update_theme_scrollbar_width): New function.
14084 (xg_get_default_scrollbar_width): Move code to
14085 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
14086 (xg_initialize): Call update_theme_scrollbar_width.
14088 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
14090 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
14092 2011-06-12 Martin Rudalics <rudalics@gmx.at>
14094 * frame.c (make_frame): Call other_buffer_safely instead of
14097 * window.c (temp_output_buffer_show): Call display_buffer with
14098 second argument Vtemp_buffer_show_specifiers and reset latter
14099 immediately after the call.
14100 (Vtemp_buffer_show_specifiers): New variable.
14101 (auto_window_vscroll_p, next_screen_context_lines)
14102 (Vscroll_preserve_screen_position): Remove leading asterisks from
14105 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
14107 Fix minor problems found by GCC 4.6.0 static checking.

14109 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
14110 (record_buffer): Remove unused local.
14111 * frame.c (other_visible_frames, frame_buffer_list): Now static.

14122 (update_hints_inhibit): Remove; never set. All uses removed.
14123 * widgetprv.h (emacsFrameClassRec): Remove decl.
14124 * window.c (delete_deletable_window): Now returns void, since it
14125 wasn't returning anything.
14126 (compare_window_configurations): Remove unused locals.
14127 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
14128 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
14129 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
14130 the same widths as pointers. This follows up on the 2011-05-06 patch.
14131 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.

14142 * image.c (gif_load): Add animation frame delay to the metadata.
14143 (syms_of_image): Use DEFSYM. New symbol `delay'.
14145 2011-06-11 Martin Rudalics <rudalics@gmx.at>
14147 * window.c (delete_deletable_window): Re-add.
14148 (Fset_window_configuration): Rewrite to handle dead buffers and
14149 consequently deletable windows.
14150 (window_tree, Fwindow_tree): Remove. Supply functionality in
14152 (compare_window_configurations): Simplify code.
14154 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
14156 * image.c (imagemagick_load_image): Fix type mismatch.

14163 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
14164 Qclone_number. Remove external declaration of Qdelete_window.
14165 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
14167 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
14168 Run Qbuffer_list_update_hook if allowed.

14170 buffer list implementation.
14171 (other_buffer_safely): New function.

14177 functions. Run Qbuffer_list_update_hook if allowed.
14178 (Frecord_buffer, Funrecord_buffer): New functions.
14179 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
14180 Move switch-to-buffer to window.el.
14181 (bury-buffer): Move to window.el.
14182 (Vbuffer_list_update_hook): New variable.

14192 * window.c: Declare Qdelete_window static again. Move down
14193 declaration of select_count.
14194 (Fnext_window, Fprevious_window): Rewrite doc-strings.
14195 (Fother_window): Move to window.el.

14282 * window.c: Remove declarations of Qwindow_size_fixed,
14283 window_min_size_1, window_min_size_2, window_min_size,
14284 size_window, window_fixed_size_p, enlarge_window, delete_window.
14285 Remove static from declaration of Qdelete_window, it's
14286 temporarily needed by Fbury_buffer.
14287 (replace_window): Don't assign orig_top_line and
14289 (Fdelete_window, delete_window): Remove. Window deletion is

14291 (window_loop): Remove DELETE_OTHER_WINDOWS case.
14292 Replace Fdelete_window calls with calls to Qdelete_window.
14293 (Fdelete_other_windows): Remove. Deleting other windows is
14294 handled by window.el.

14666 value of a `display' property is a "replacing spec".
14667 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
14668 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

14698 * gnutls.c: Use Emacs's memory allocators.
14699 Without this change, the gnutls library would invoke malloc etc.
14700 directly, which causes problems on non-SYNC_INPUT hosts, and which
14701 runs afoul of improving memory_full behavior. (Bug#8761)
14702 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
14703 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
14704 xfree instead of the default malloc, realloc, free.
14705 (Fgnutls_boot): No need to check for memory allocation failure,
14706 since xmalloc does that for us.

14725 (xpm_put_color_table_h):
14726 * lisp.h (struct Lisp_Hash_Table):
14727 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
14728 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
14729 for hashes and hash indexes, instead of 'unsigned' and 'int'.
14730 * alloc.c (allocate_vectorlike):
14731 Check for overflow in vector size calculations.
14732 * ccl.c (ccl_driver):
14733 Check for overflow when converting EMACS_INT to int.
14734 * fns.c, image.c: Remove unnecessary static decls that would otherwise
14735 need to be updated by these changes.
14736 * fns.c (make_hash_table, maybe_resize_hash_table):
14737 Check for integer overflow with large hash tables.
14738 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
14739 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
14740 (SXHASH_REDUCE): New macro.
14741 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
14742 Use it instead of discarding useful hash info with large hash values.
14743 (sxhash_float): New function.
14744 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
14745 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
14746 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
14747 Rewrite to use FIXNUM_BITS, as this simplifies things.
14748 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
14749 Adjust signatures to match updated version of code.
14750 (consing_since_gc): Now EMACS_INT, since a single hash table can
14751 use more than INT_MAX bytes.
14753 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
14755 Make it possible to build with GCC-4.6+ -O2 -flto.

14759 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
14761 * minibuf.c (get_minibuffer, read_minibuf_unwind):
14762 Call minibuffer-inactive-mode.
14764 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
14766 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
14767 Update dependencies.
14769 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14771 * data.c (init_data): Remove code for UTS, this system is not
14774 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14776 Don't force ./temacs to start in terminal mode.
14778 * frame.c (make_initial_frame): Initialize faces in all cases, not
14779 only when CANNOT_DUMP is defined.
14780 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
14782 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14784 * dispnew.c (add_window_display_history): Use const for the string
14785 pointer. Remove declaration, not needed.
14787 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
14789 Use 'inline', not 'INLINE'.
14790 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
14791 * alloc.c, fontset.c (INLINE): Remove.
14792 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
14793 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
14794 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
14795 * gmalloc.c (register_heapinfo): Use inline unconditionally.
14796 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
14798 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
14800 Make it possible to run ./temacs.
14802 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
14803 syms_of_callproc does the same thing. Remove test for
14804 "initialized", do it in the caller.
14805 * emacs.c (main): Avoid calling set_initial_environment when dumping.
14807 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
14809 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
14810 (read_minibuf): Use get_minibuffer.
14811 (syms_of_minibuf): Use DEFSYM.
14812 (Qmetadata): New var.
14813 * data.c (Qbuffer): Don't make it static.
14814 (syms_of_data): Use DEFSYM.
14816 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
14818 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
14819 (CCL_CODE_MIN): New macro.
14821 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
14823 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
14825 * eval.c (Qdebug): Now static.
14826 * lisp.h (Qdebug): Remove decl. This reverts a part of the
14827 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
14828 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
14830 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14832 * image.c: Various fixes to ImageMagick code comments.
14833 (Fimagemagick_types): Doc fix.
14835 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
14837 Minor fixes prompted by GCC 4.6.0 warnings.
14839 * xselect.c (converted_selections, conversion_fail_tag): Now static.
14841 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
14842 (x_clipboard_manager_save_all): Move extern decl to ...
14843 * xterm.h: ... here, so that it can be checked for consistency.
14845 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
14847 * xselect.c (x_clipboard_manager_save_frame)
14848 (x_clipboard_manager_save_all): New functions.
14849 (Fx_clipboard_manager_save): Lisp function deleted.
14851 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
14852 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
14854 * xterm.h: Update prototype.
14856 2011-05-28 William Xu <william.xwl@gmail.com>
14858 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
14859 exiting (Bug#8239).
14861 2011-05-28 Jim Meyering <meyering@redhat.com>
14863 Avoid a sign-extension bug in crypto_hash_function.
14864 * fns.c (to_uchar): Define.
14865 (crypto_hash_function): Use it to convert some newly-signed
14866 variables to unsigned, to avoid sign-extension bugs. For example,
14867 without this change, (md5 "truc") would evaluate to
14868 45723a2aff78ff4fff7fff1114760e62 rather than the expected
14869 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
14870 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
14872 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14874 Integer overflow fixes.
14876 * dbusbind.c: Serial number integer overflow fixes.
14877 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
14878 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
14879 to hold a serial number that is too large for a fixnum.
14880 (Fdbus_method_return_internal, Fdbus_method_error_internal):
14881 Check for serial numbers out of range. Decode any serial number
14882 that was so large that it became a float. (Bug#8722)
14884 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
14885 (Fdbus_call_method, Fdbus_call_method_asynchronously):
14886 Use XFASTINT rather than XUINT when numbers are nonnegative.
14887 (xd_append_arg, Fdbus_method_return_internal):
14888 (Fdbus_method_error_internal): Likewise. Also, for unsigned
14889 arguments, check that Lisp number is nonnegative, rather than
14890 silently wrapping negative numbers around. (Bug#8722)
14891 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
14894 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
14896 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
14898 ccl: Add integer overflow checks.
14899 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
14900 (IN_INT_RANGE): New macros.
14901 (ccl_driver): Use them to check for integer overflow when
14902 decoding a CCL program. Many of the new checks are whether XINT (x)
14903 fits in int; it doesn't always, on 64-bit hosts. The new version
14904 doesn't catch all possible integer overflows, but it's an
14905 improvement. (Bug#8719)
14907 * alloc.c (make_event_array): Use XINT, not XUINT.
14908 There's no need for unsigned here.
14910 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
14911 This follows up to the 2011-05-06 change that substituted uintptr_t
14912 for EMACS_INT. This case wasn't caught back then.
14914 Rework Fformat to avoid integer overflow issues.
14915 * editfns.c: Include <float.h> unconditionally, as it's everywhere
14916 now (part of C89). Include <verify.h>.
14917 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
14918 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
14919 (Fformat): Avoid the prepass trying to compute sizes; it was only
14920 approximate and thus did not catch overflow reliably. Instead, walk
14921 through the format just once, formatting and computing sizes as we go,
14922 checking for integer overflow at every step, and allocating a larger
14923 buffer as needed. Keep track separately whether the format is
14924 multibyte. Keep only the most-recently calculated precision, rather
14925 than them all. Record whether each argument has been converted to
14926 string. Use EMACS_INT, not int, for byte and char and arg counts.
14927 Support field widths and precisions larger than INT_MAX. Avoid
14928 sprintf's undefined behavior with conversion specifications such as %#d
14929 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
14930 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
14931 formatting out-of-range floating point numbers with int
14932 formats. (Bug#8668)
14934 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
14936 * data.c: Avoid integer truncation in expressions involving floats.
14937 * data.c: Include <intprops.h>.
14938 (arith_driver): When there's an integer overflow in an expression
14939 involving floating point, convert the integers to floating point
14940 so that the resulting value does not suffer from catastrophic
14941 integer truncation. For example, on a 64-bit host (* 4
14942 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
14943 Do not rely on undefined behavior after integer overflow.
14945 merge count_size_as_multibyte, parse_str_to_multibyte
14946 * character.c, character.h (count_size_as_multibyte):
14947 Rename from parse_str_to_multibyte; all uses changed.
14948 Check for integer overflow.
14949 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
14950 since it's now a duplicate of the other. This is more of
14951 a character than a buffer op, so better that it's in character.c.
14952 * fns.c, print.c: Adjust to above changes.
14954 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
14956 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
14958 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14960 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14961 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
14962 (x_clipboard_manager_save): Now static.
14963 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
14965 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14966 (crypto_hash_function): Now static.
14967 Fix pointer signedness problems. Avoid unnecessary initializations.
14969 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
14971 * termhooks.h (Vselection_alist): Make it terminal-local.
14973 * terminal.c (create_terminal): Initialize it.
14975 * xselect.c: Support for clipboard managers.
14976 (Vselection_alist): Move to termhooks.h as terminal-local var.
14977 (LOCAL_SELECTION): New macro.
14978 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
14979 (symbol_to_x_atom): Remove gratuitous arg.
14980 (x_handle_selection_request, lisp_data_to_selection_data)
14981 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
14982 (x_own_selection, x_get_local_selection, x_convert_selection):
14983 New arg, specifying work frame. Use terminal-local Vselection_alist.
14984 (some_frame_on_display): Delete unused function.
14985 (Fx_own_selection_internal, Fx_get_selection_internal)
14986 (Fx_disown_selection_internal, Fx_selection_owner_p)
14987 (Fx_selection_exists_p): New optional frame arg.
14988 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
14989 (x_handle_selection_clear): Don't treat other terminals with the
14990 same keyboard specially. Use the terminal-local Vselection_alist.
14991 (x_clear_frame_selections): Use Frun_hook_with_args.
14993 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
14995 * xterm.h: Add support for those atoms.
14997 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
14999 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
15000 (converted_selections, conversion_fail_tag): New global variables.
15001 (x_selection_request_lisp_error): Free the above.
15002 (x_get_local_selection): Remove unnecessary code.
15003 (x_reply_selection_request): Args changed; handle arbitrary array
15004 of converted selections stored in converted_selections.
15005 Separate the XChangeProperty and SelectionNotify steps.
15006 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
15007 (x_convert_selection): New function.
15008 (x_handle_selection_event): Simplify.
15009 (x_get_foreign_selection): Don't ignore incoming requests while
15010 waiting for an answer; this will fail when we implement
15011 SAVE_TARGETS, and seems unnecessary anyway.
15012 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
15013 (Vx_sent_selection_functions): Doc fix.
15015 2011-05-26 Leo Liu <sdl.web@gmail.com>
15017 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
15019 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15021 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
15023 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
15024 for fringe update if it has periodic bitmap.
15025 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
15026 and fringe_bitmap_periodic_p.
15028 * fringe.c (get_fringe_bitmap_data): New function.
15029 (draw_fringe_bitmap_1, update_window_fringes): Use it.
15030 (update_window_fringes): Record periodicity of fringe bitmap in glyph
15031 row. Mark glyph row for fringe update if periodicity changed.
15033 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
15034 for fringe update unless it has periodic bitmap.
15036 2011-05-25 Kenichi Handa <handa@m17n.org>
15038 * xdisp.c (get_next_display_element): Set correct it->face_id for
15039 a static composition.
15041 2011-05-24 Leo Liu <sdl.web@gmail.com>

15052 * gnutls.c: Remove unused macros.
15053 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
15054 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
15055 Remove macros that are defined and never used.
15056 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
15058 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
15060 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
15061 (Fx_get_selection_internal): Minor cleanup.
15062 (Fx_own_selection_internal): Rename arguments for consistency with
15065 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
15067 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.

15086 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
15087 report_file_error introduced by the change from 2011-05-07.
15089 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
15091 * systime.h (Time): Define only if emacs is defined.
15092 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
15093 where the include path doesn't have X11/X.h by default. See
15094 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
15096 2011-05-20 Kenichi Handa <handa@m17n.org>
15098 * composite.c (find_automatic_composition): Fix previous change.
15100 2011-05-20 Glenn Morris <rgm@gnu.org>
15102 * lisp.mk: New file, split from Makefile.in.
15103 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
15104 (shortlisp): Remove.
15105 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
15107 2011-05-19 Glenn Morris <rgm@gnu.org>
15109 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
15110 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
15111 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
15112 (lisp): Set the order to that of loadup.el.
15113 (shortlisp): Make it a copy of $lisp.
15114 (SOME_MACHINE_LISP): Remove.
15115 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
15116 Use just $shortlisp, not $SOME_MACHINE_LISP too.
15118 2011-05-18 Kenichi Handa <handa@m17n.org>
15120 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
15121 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
15122 (find_automatic_composition): Mostly rewrite for efficiency.
15124 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
15126 * makefile.w32-in: Update dependencies.
15128 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
15130 * menu.c: Include limits.h (fixes the MS-Windows build broken by
15131 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
15133 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
15135 Fix some integer overflow issues, such as string length overflow.
15137 * insdel.c (count_size_as_multibyte): Check for string overflow.
15139 * character.c (lisp_string_width): Check for string overflow.
15140 Use EMACS_INT, not int, for string indexes and lengths; in
15141 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
15142 the resulting string length overflows an EMACS_INT; instead,
15143 report a string overflow if no precision given. When checking for
15144 precision exhaustion, use a check that cannot possibly have
15145 integer overflow. (Bug#8675)
15146 * character.h (lisp_string_width): Adjust to new signature.
15148 * alloc.c (string_overflow): New function.
15149 (Fmake_string): Use it. This doesn't change behavior, but saves
15150 a few bytes and will simplify future changes.
15151 * character.c (string_escape_byte8): Likewise.
15152 * lisp.h (string_overflow): New decl.
15154 Fixups, following up to the user-interface timestamp change.
15155 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
15156 for UI timestamps, instead of unsigned long.
15157 * msdos.c (mouse_get_pos): Likewise.
15158 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
15159 * w32gui.h (Time): Define by including "systime.h" rather than by
15160 declaring it ourselves. (Bug#8664)
15162 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
15163 * image.c (clear_image_cache): Likewise.
15165 * term.c (term_mouse_position): Don't assume time_t wraparound.
15167 Be more systematic about user-interface timestamps.
15168 Before, the code sometimes used 'Time', sometimes 'unsigned long',
15169 and sometimes 'EMACS_UINT', to represent these timestamps.
15170 This change causes it to use 'Time' uniformly, as that's what X uses.
15171 This makes the code easier to follow, and makes it easier to catch
15172 integer overflow bugs such as Bug#8664.
15173 * frame.c (Fmouse_position, Fmouse_pixel_position):
15174 Use Time, not unsigned long, for user-interface timestamps.
15175 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
15176 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
15177 * keyboard.h (last_event_timestamp): Likewise.
15178 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
15179 * menu.h (xmenu_show): Likewise.
15180 * term.c (term_mouse_position): Likewise.
15181 * termhooks.h (struct input_event.timestamp): Likewise.
15182 (struct terminal.mouse_position_hook): Likewise.
15183 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
15184 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
15185 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
15186 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
15187 what it was before.
15188 * menu.h, termhooks.h: Include "systime.h", for Time.
15190 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
15191 Don't assume that the difference between two unsigned long values
15192 can fit into an integer. At this point, we know button_down_time
15193 <= event->timestamp, so the difference must be nonnegative, so
15194 there's no need to cast the result if double-click-time is
15195 nonnegative, as it should be; check that it's nonnegative, just in
15196 case. This bug is triggered when events are more than 2**31 ms
15197 apart (about 25 days). (Bug#8664)
15199 * xselect.c (last_event_timestamp): Remove duplicate decl.
15200 (x_own_selection): Remove needless cast to unsigned long.
15202 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
15203 that always fit in int. Use a sentinel instead of a counter, to
15204 avoid a temp and to allay GCC's concerns about possible int overflow.
15205 * frame.h (struct frame): Use int for menu_bar_items_used
15206 instead of EMACS_INT, since it always fits in int.
15208 * menu.c (grow_menu_items): Check for int overflow.
15210 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
15212 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
15213 Before, the code was not consistent. These values cannot exceed
15214 2**31 - 1 so there's no need to make them unsigned.
15215 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
15216 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
15217 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
15219 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
15221 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
15222 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
15223 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
15224 presumably because the widths might not match.
15226 * window.c (size_window): Avoid needless test at loop start.
15228 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
15230 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
15232 2011-05-12 Drew Adams <drew.adams@oracle.com>
15234 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
15236 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15238 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
15239 `width' to `bar_area_x' and `bar_area_width', respectively.
15240 (x_scroll_run): Take account of fringe background extension.
15242 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
15243 Rename local vars `left' and `width' to `bar_area_x' and
15244 `bar_area_width', respectively.
15245 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
15246 background extension.
15248 2011-05-10 Jim Meyering <meyering@redhat.com>
15250 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
15252 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
15254 * image.c (Finit_image_library): Return t for built-in image types,
15255 like pbm and xbm. (Bug#8640)
15257 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
15259 * w32menu.c (set_frame_menubar): Fix submenu allocation.
15261 2011-05-07 Eli Zaretskii <eliz@gnu.org>
15263 * w32console.c (Fset_screen_color): Doc fix.
15264 (Fget_screen_color): New function.
15265 (syms_of_ntterm): Defsubr it.
15267 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
15268 unlink the temporary file if Fcall_process didn't create it in the
15270 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
15271 child process will be redirected to a file specified with `:file'.
15272 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
15273 cue to call_process_cleanup not to close that handle.
15275 2011-05-07 Ben Key <bkey76@gmail.com>
15277 * makefile.w32-in: The bootstrap-temacs rule now makes use of
15278 one of two shell specific rules, either bootstrap-temacs-CMD or
15279 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
15280 to the previous implementation of the bootstrap-temacs rule.
15281 The bootstrap-temacs-CMD rule is similar to the previous
15282 implementation of the bootstrap-temacs rule except that it
15283 makes use of the ESC_CFLAGS variable instead of the CFLAGS
15286 These changes, along with some changes to nt/configure.bat,
15287 nt/gmake.defs, and nt/nmake.defs, are required to extend my
15288 earlier fix to add support for --cflags and --ldflags options
15289 that include quotes so that it works whether make uses cmd or
15292 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
15294 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
15295 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
15297 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
15298 a string. Handle both cases.
15299 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
15300 (Fdbus_register_method): Use Qinvalid_function.
15302 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
15304 * makefile.w32-in: Update dependencies.
15305 (LISP_H): Add inttypes.h and stdin.h.
15306 (PROCESS_H): Add unistd.h.
15308 2011-05-06 Eli Zaretskii <eliz@gnu.org>
15310 * lread.c: Include limits.h (fixes the MS-Windows build broken by
15311 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
15313 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
15315 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
15317 * term.c (vfatal): Remove stray call to va_end.
15318 It's not needed and the C Standard doesn't allow it here anyway.
15320 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
15321 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
15323 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
15326 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
15328 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15330 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
15332 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
15334 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
15336 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
15337 * charset.c (Fdefine_charset_internal): Don't initialize
15338 charset.code_space[15]. The value was garbage, on hosts with
15339 32-bit int (Bug#8600).
15341 * lread.c (read_integer): Be more consistent with string-to-number.
15342 Use string_to_number to do the actual conversion; this avoids
15343 rounding errors and fixes some other screwups. Without this fix,
15344 for example, #x1fffffffffffffff was misread as -2305843009213693952.
15345 (digit_to_number): Move earlier, for benefit of read_integer.
15346 Return -1 if the digit is out of range for the base, -2 if it is
15347 not a digit in any supported base. (Bug#8602)
15349 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
15351 * dispnew.c (scrolling_window): Return 1 if we scrolled,
15352 to match comment at start of function. This also removes a
15353 GCC warning about overflow in a 32+64-bit port.
15355 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
15357 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
15358 Reported by Stefan Monnier in
15359 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
15360 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
15361 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
15363 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
15364 (EMACS_UINTPTR): Likewise, with uintptr_t.
15366 * lisp.h: Prefer 64-bit EMACS_INT if available.
15367 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
15368 on 32-bit hosts that have 64-bit int, so that they can access
15370 However, temporarily disable this change unless the temporary
15371 symbol WIDE_EMACS_INT is defined.
15373 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
15375 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
15376 This removes an assumption that EMACS_INT and long are the same
15377 width as pointers. The assumption is true for Emacs porting targets
15378 now, but we want to make other targets possible.
15379 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
15380 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
15381 In the rest of the code, change types of integers that hold casted
15382 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
15383 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
15384 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
15385 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
15386 No need to cast type when ORing.
15387 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
15388 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
15389 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
15390 assume EMACS_INT is the same width as char *.
15391 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
15392 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
15393 Remove no-longer-needed casts.
15394 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
15395 (xg_tool_bar_help_callback, xg_make_tool_item):
15396 Use EMACS_INTPTR to hold an integer
15397 that will be cast to void *; this can avoid a GCC warning
15398 if EMACS_INT is not the same width as void *.
15399 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
15400 * xdisp.c (display_echo_area_1, resize_mini_window_1):
15401 (current_message_1, set_message_1):
15402 Use a local to convert to proper width without a cast.
15403 * xmenu.c (dialog_selection_callback): Likewise.
15405 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
15406 Also, don't assume VALBITS / RAND_BITS is less than 5,
15407 and don't rely on undefined behavior when shifting a 1 left into
15409 * lisp.h (get_random): Change signature to match.
15411 * lread.c (hash_string): Use size_t, not int, for hash computation.
15412 Normally we prefer signed values; but hashing is special, because
15413 it's better to use unsigned division on hash table sizes so that
15414 the remainder is nonnegative. Also, size_t is the natural width
15415 for hashing into memory. The previous code used 'int', which doesn't
15416 retain enough info to hash well into very large tables.
15417 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
15419 * dbusbind.c: Don't possibly lose pointer info when converting.
15420 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
15421 Use XPNTR rather than XHASH, so that the high-order bits of
15422 the pointer aren't lost when converting through void *.
15424 * eval.c (Fautoload): Don't double-shift a pointer.
15426 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
15428 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
15430 * gnutls.c (DEF_GNUTLS_FN):
15431 * image.c (DEF_IMGLIB_FN): Make function pointers static.
15433 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
15435 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
15438 2011-05-05 Eli Zaretskii <eliz@gnu.org>
15440 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
15441 New version that can reserve upto 2GB of heap space.
15443 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
15445 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
15447 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
15449 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
15450 `gnutls_certificate_set_x509_key_file'.
15452 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
15454 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
15455 Update dependencies.
15457 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15459 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
15460 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
15461 Remove unused parameter `fildes'.
15462 * process.c (read_process_output, send_process): Don't pass it.
15464 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15466 Fix previous change: the library cache is defined in w32.c.
15467 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
15468 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
15470 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
15472 Implement dynamic loading of GnuTLS on Windows.
15474 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
15475 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
15476 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
15479 * gnutls.c (Qgnutls_dll): Define.
15480 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
15481 (gnutls_*): Declare function pointers.
15482 (init_gnutls_functions): New function to initialize function pointers.
15483 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
15484 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
15485 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
15486 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
15487 (emacs_gnutls_write, emacs_gnutls_read)
15488 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
15489 (Fgnutls_available_p): New function.
15490 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
15491 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
15492 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
15494 * image.c: Include w32.h.
15495 (Vimage_type_cache): Delete.
15496 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
15497 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
15498 (w32_delayed_load): Move to w32.c.
15500 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
15502 * w32.c (QCloaded_from, Vlibrary_cache): Define.
15503 (w32_delayed_load): Move from image.c. When loading a library, record
15504 its filename in the :loaded-from property of the library id.
15505 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
15506 Initialize and staticpro them.
15507 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
15509 * process.c: Include lisp.h before w32.h, not after.
15510 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
15511 instead of gnutls_record_check_pending.
15513 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
15515 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
15517 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
15518 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
15521 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
15523 * xterm.c (x_set_frame_alpha): Do not set property on anything
15524 else than FRAME_X_OUTER_WINDOW (Bug#8608).
15526 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
15528 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
15530 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
15532 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
15533 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

15539 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
15540 (Qgnutls_bootprop_callbacks_verify): Make static.
15542 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
15544 * callproc.c: Indentation fixup.
15546 * sysdep.c (wait_for_termination_1): Make static.
15547 (wait_for_termination, interruptible_wait_for_termination):
15548 Move after wait_for_termination_1.
15550 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
15552 * sysdep.c (interruptible_wait_for_termination): New function
15553 which is like wait_for_termination, but allows keyboard
15556 * callproc.c (Fcall_process): Add (:file "file") as an option for
15558 (Fcall_process_region): Ditto.
15560 2011-04-30 Eli Zaretskii <eliz@gnu.org>
15562 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
15563 rather than `XVECTOR (FOO)->size'.
15565 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
15566 inttypes.h, as a gnulib replacement is used if it not available in
15569 2011-04-21 Eli Zaretskii <eliz@gnu.org>
15571 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
15572 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
15573 of MOST_POSITIVE_FIXNUM. (Bug#8528)
15575 * coding.c (coding_alloc_by_realloc): Error out if destination
15576 will grow beyond MOST_POSITIVE_FIXNUM.
15577 (decode_coding_emacs_mule): Abort if there isn't enough place in
15578 charbuf for the composition carryover bytes. Reserve an extra
15579 space for up to 2 characters produced in a loop.
15580 (decode_coding_iso_2022): Abort if there isn't enough place in
15581 charbuf for the composition carryover bytes.
15583 2011-04-21 Eli Zaretskii <eliz@gnu.org>
15585 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
15586 aborting when %lld or %lll format is passed.
15587 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
15588 %llo or %llx format is passed. (Bug#8545)
15590 * window.c (window_scroll_line_based): Use a marker instead of
15591 simple variables to record original value of point. (Bug#7952)
15593 * doprnt.c (doprnt): Fix the case where a multibyte sequence
15594 produced by %s or %c overflows available buffer space. (Bug#8545)
15596 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
15598 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
15599 (SIZE_MAX): Move defn after all includes, as they might #define it.
15601 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15603 * w32.c (init_environment): Warn about defaulting HOME to C:\.
15605 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15607 * keyboard.c (Qdelayed_warnings_hook): Define.
15608 (command_loop_1): Run `delayed-warnings-hook'
15609 if Vdelayed_warnings_list is non-nil.
15610 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
15611 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
15613 2011-04-28 Eli Zaretskii <eliz@gnu.org>
15615 * doprnt.c (doprnt): Don't return value smaller than the buffer
15616 size if the message was truncated. (Bug#8545).
15618 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
15620 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
15621 (Fx_window_property): #if-0 the whole functions, not just the bodies.
15623 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15625 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
15627 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
15629 * makefile.w32-in: Update dependencies.
15631 2011-04-27 Eli Zaretskii <eliz@gnu.org>
15633 Improve `doprnt' and its usage. (Bug#8545)
15634 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
15635 `format_end'. Remove support for %l as a conversion specifier.
15636 Don't use xrealloc. Improve diagnostics when the %l size modifier
15637 is used. Update the commentary.
15639 * eval.c (verror): Simplify calculation of size_t.
15641 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
15644 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
15646 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
15649 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
15651 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
15652 This makes this file independent of the recent pseudovector change.
15654 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
15656 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
15658 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
15659 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
15660 Remove unused local.
15661 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
15663 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
15664 GCC 4.6.0 optimizes based on type-based alias analysis.
15665 For example, if b is of type struct buffer * and v of type struct
15666 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
15667 != &v->size, and therefore "v->size = 1; b->size = 2; return
15668 v->size;" must therefore return 1. This assumption is incorrect
15669 for Emacs, since it type-puns struct Lisp_Vector * with many other
15670 types. To fix this problem, this patch adds a new type struct
15671 vectorlike_header that documents the constraints on layout of vectors
15672 and pseudovectors, and helps optimizing compilers not get fooled
15673 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
15674 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
15675 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
15677 (XSETPVECTYPE): Rewrite in terms of new macro.
15678 (XSETPVECTYPESIZE): New macro, specifying both type and size.
15679 This is a bit clearer, and further avoids the possibility of
15680 undesirable aliasing.
15681 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
15682 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
15683 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
15684 since Lisp_Subr is a special case (no "next" field).
15685 (ASIZE): Now uses header.size rather than size.
15686 All previous uses of XVECTOR (foo)->size replaced to use this macro,
15687 to avoid the hassle of writing XVECTOR (foo)->header.size.
15688 (struct vectorlike_header): New type.
15689 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
15690 object, to help avoid aliasing.
15691 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
15692 (SUBRP): Likewise, since Lisp_Subr is a special case.
15693 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
15694 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
15695 (struct Lisp_Hash_Table): Combine first two members into a single
15696 struct vectorlike_header member. All uses of "size" and "next" members
15697 changed to be "header.size" and "header.next".
15698 * buffer.h (struct buffer): Likewise.
15699 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
15700 * frame.h (struct frame): Likewise.
15701 * process.h (struct Lisp_Process): Likewise.
15702 * termhooks.h (struct terminal): Likewise.
15703 * window.c (struct save_window_data, struct saved_window): Likewise.
15704 * window.h (struct window): Likewise.
15705 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
15706 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
15707 * buffer.c (init_buffer_once): Likewise.
15708 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
15710 * process.c (Fformat_network_address): Use local var for size,
15713 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
15715 Make the Lisp reader and string-to-float more consistent (Bug#8525)
15716 * data.c (atof): Remove decl; no longer used or needed.
15717 (digit_to_number): Move to lread.c.
15718 (Fstring_to_number): Use new string_to_number function, to be
15719 consistent with how the Lisp reader treats infinities and NaNs.
15720 Do not assume that floating-point numbers represent EMACS_INT
15721 without losing information; this is not true on most 64-bit hosts.
15722 Avoid double-rounding errors, by insisting on integers when
15723 parsing non-base-10 numbers, as the documentation specifies.
15724 * lisp.h (string_to_number): New decl, replacing ...
15725 (isfloat_string): Remove.
15726 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
15727 (read1): Do not accept +. and -. as integers; this
15728 appears to have been a coding error. Similarly, do not accept
15729 strings like +-1e0 as floating point numbers. Do not report
15730 overflow for integer overflows unless the base is not 10 which
15731 means we have no simple and reliable way to continue.
15732 Break out the floating-point parsing into a new
15733 function string_to_number, so that Fstring_to_number parses
15734 floating point numbers consistently with the Lisp reader.
15735 (digit_to_number): Move here from data.c. Make it static inline.
15736 (E_CHAR, EXP_INT): Remove, replacing with ...
15737 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
15738 (string_to_number): New function, replacing isfloat_string.
15739 This function checks for valid syntax and produces the resulting
15740 Lisp float number too. Rework it so that string-to-number
15741 no longer mishandles examples like "1.0e+". Use strtoumax,
15742 so that overflow for non-base-10 numbers is reported only when
15743 there's no portable and simple way to convert to floating point.
15745 * textprop.c (set_text_properties_1): Rewrite for clarity,
15746 and to avoid GCC warning about integer overflow.
15748 * intervals.h (struct interval): Use EMACS_INT for members
15749 where EMACS_UINT might cause problems. See
15750 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
15751 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
15752 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
15754 (offset_intervals): Tell GCC not to worry about length overflow
15755 when negating a negative length.
15757 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
15758 (overrun_check_free): Likewise.
15760 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
15761 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
15764 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15765 (gnutls_make_error): Rename local to avoid shadowing.
15766 (gnutls_emacs_global_deinit): ifdef out; not used.
15767 (Fgnutls_boot): Use const for pointer to readonly storage.
15768 Comment out unused local. Fix pointer signedness problems.
15770 * lread.c (openp): Don't stuff size_t into an 'int'.
15771 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
15772 about possible signed overflow.
15774 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
15775 (GDK_KEY_g): Don't define if already defined.
15776 (xg_prepare_tooltip): Avoid pointer signedness problem.
15777 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
15779 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
15780 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
15782 * xfns.c (Fx_window_property): Simplify a bit,
15783 to make a bit faster and to avoid GCC 4.6.0 warning.
15784 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
15786 * fns.c (internal_equal): Don't assume size_t fits in int.
15788 * alloc.c (compact_small_strings): Tighten assertion a little.
15790 Replace pEd with more-general pI, and fix some printf arg casts.
15791 * lisp.h (pI): New macro, generalizing old pEd macro to other
15792 conversion specifiers. For example, use "...%"pI"d..." rather
15793 than "...%"pEd"...".
15794 (pEd): Remove. All uses replaced with similar uses of pI.
15795 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
15796 * alloc.c (check_pure_size): Don't overflow by converting size to int.
15797 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
15798 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
15799 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
15800 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
15801 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
15803 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
15804 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
15805 * print.c (safe_debug_print, print_object): Likewise.
15806 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
15808 Use pI instead of if-then-else-abort. Use %p to avoid casts,
15809 avoiding the 0 flag, which is not portable.
15810 * process.c (Fmake_network_process): Use pI to avoid cast.
15811 * region-cache.c (pp_cache): Likewise.
15812 * xdisp.c (decode_mode_spec): Likewise.
15813 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
15814 behavior on 64-bit hosts with printf arg.
15815 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
15816 (x_stop_queuing_selection_requests): Likewise.
15817 (x_get_window_property): Don't truncate byte count to an 'int'
15820 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
15821 here, since it parses constructs like leading '-' and spaces,
15822 which are not wanted; and it overflows with large numbers.
15823 Instead, simply match F[0-9]+, which is what is wanted anyway.
15825 * alloc.c: Remove unportable assumptions about struct layout.
15826 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
15827 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
15828 (allocate_vectorlike, make_pure_vector): Use the new macros,
15829 plus offsetof, to remove unportable assumptions about struct layout.
15830 These assumptions hold on all porting targets that I know of, but
15831 they are not guaranteed, they're easy to remove, and removing them
15832 makes further changes easier.
15834 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
15835 This doesn't fix a bug but makes the code clearer.
15836 (string_overrun_cookie): Now const. Use initializers that
15837 don't formally overflow signed char, to avoid warnings.
15838 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
15839 can cause Emacs to crash when string overrun checking is enabled.
15840 (allocate_buffer): Don't assume sizeof (struct buffer) is a
15841 multiple of sizeof (EMACS_INT); it need not be, if
15842 alignof(EMACS_INT) < sizeof (EMACS_INT).
15843 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
15845 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
15847 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
15849 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
15851 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
15852 supposed to be handshaking. (Bug#8556)
15853 Reported by Paul Eggert <eggert@cs.ucla.edu>.
15855 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
15857 * lisp.h (Qdebug): List symbol.
15858 * eval.c (Qdebug): Restore global linkage.

15860 (handle_user_signal): Break into debugger when debug-on-event
15861 matches the current signal symbol.
15863 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
15865 * alloc.c (check_sblock, check_string_bytes)
15866 (check_string_free_list): Convert to standard C.
15868 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
15870 * w32.c (emacs_gnutls_push): Fix typo.
15872 2011-04-25 Eli Zaretskii <eliz@gnu.org>
15874 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
15875 "cast to pointer from integer of different size".
15877 Improve doprnt and its use in verror. (Bug#8545)
15878 * doprnt.c (doprnt): Document the set of format control sequences
15879 supported by the function. Use SAFE_ALLOCA instead of always
15882 * eval.c (verror): Don't limit the buffer size at size_max-1, that
15883 is one byte too soon. Don't use xrealloc; instead xfree and
15886 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
15888 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
15891 * gnutls.c: Renamed global_initialized to
15892 gnutls_global_initialized. Added internals for the
15893 :verify-hostname-error, :verify-error, and :verify-flags
15894 parameters of `gnutls-boot' and documented those parameters in the
15895 docstring. Start callback support.
15896 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
15897 unless a fatal error occurred. Call gnutls_alert_send_appropriate
15898 on error. Return error code.
15899 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
15900 (emacs_gnutls_read): Likewise.
15901 (Fgnutls_boot): Return handshake error code.
15902 (emacs_gnutls_handle_error): New function.
15903 (wsaerror_to_errno): Likewise.

15958 changes in globals.h immediately force recompilation.
15959 (TAGS): Depend on $(CURDIR)/m/intel386.h and
15960 $(CURDIR)/s/ms-w32.h.
15961 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

15965 <char-direction-table>: Deleted.
15967 2011-04-23 Eli Zaretskii <eliz@gnu.org>
15969 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
15970 * doprnt.c: Include limits.h.
15971 (SIZE_MAX): New macro.
15972 (doprnt): Return a size_t value. 2nd arg is now size_t.
15973 Many local variables are now size_t instead of int or unsigned.
15974 Improve overflow protection. Support `l' modifier for integer
15975 conversions. Support %l conversion. Don't assume an EMACS_INT
15976 argument for integer conversions and for %c.
15978 * lisp.h (doprnt): Restore prototype.
15980 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
15981 $(SRC)/character.h.
15983 * Makefile.in (base_obj): Add back doprnt.o.
15985 * deps.mk (doprnt.o): Add back prerequisites.
15986 (callint.o): Depend on character.h.
15988 * eval.c (internal_lisp_condition_case): Include the handler
15989 representation in the error message.
15990 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
15991 when breaking from the loop.
15993 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
15995 * callint.c (Fcall_interactively): When displaying error message
15996 about invalid control letter, pass the character's codepoint, not
15997 a pointer to its multibyte form. Improve display of the character
15998 in octal and display also its hex code.
16000 * character.c (char_string): Use %x to display the (unsigned)
16001 codepoint of an invalid character, to avoid displaying a bogus
16004 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
16005 `error', not SYMBOL_NAME itself.
16007 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
16008 character arguments to `error'.
16010 * charset.c (check_iso_charset_parameter): Fix incorrect argument
16011 to `error' in error message about FINAL_CHAR argument. Make sure
16012 FINAL_CHAR is a character, and use %c when it is passed as
16013 argument to `error'.
16015 2011-04-23 Eli Zaretskii <eliz@gnu.org>

16203 ns_descriptor_to_entity that were caused by using free to
16204 deallocate memory blocks that were allocated by xmalloc (via
16205 xstrdup). This caused Emacs to crash when compiled with

16225 (emacs_read, emacs_write): Use it.
16226 * process.c (send_process): Adjust to the new signatures of
16227 emacs_write and emacs_gnutls_write. Do not attempt to store

16557 * lisp.h: Remove these decls.
16559 * buffer.c (buffer_count): Remove unused var.
16561 * bidi.c (bidi_dump_cached_states): Mark as externally visible,

16563 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
16564 * dispextern.h (bidi_dump_cached_states): Remove, since it's
16565 exported only to the debugger.
16567 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
16568 * atimer.h (run_all_atimers): Remove; not exported.
16570 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
16571 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
16572 was inaccessible from Lisp.
16573 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
16574 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
16576 alloc.c: Import and export fewer symbols, and remove unused items.
16577 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
16579 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
16580 it's not optimized away by whole-program optimization.
16581 (message_enable_multibyte, free_misc): Remove.
16582 (catchlist, handlerlist, mark_backtrace):
16583 Declare only if BYTE_MARK_STACK.

16592 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
16593 (mark_backtrace): Define only if BYTE_MARK_STACK.
16594 * xdisp.c (message_enable_multibyte): Now static.
16596 Declare Lisp_Object Q* variables to be 'static' if not exported.
16597 This makes it easier for human readers (and static analyzers)
16598 to see whether these variables are used from other modules.
16599 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
16600 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

16609 Remove decls of unexported vars.
16610 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
16612 * lisp.h (DEFINE_FUNC): Make sname 'static'.
16614 Make Emacs functions such as Fatom 'static' by default.
16615 This makes it easier for human readers (and static analyzers)
16616 to see whether these functions can be called from other modules.
16617 DEFUN now defines a static function. To make the function external
16618 so that it can be used in other C modules, use the new macro DEFUE.
16619 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
16620 (Finit_image_library):
16621 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):

16623 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
16624 Remove decls, since these functions are now static.
16625 (Funintern, Fget_internal_run_time): New decls, since these functions
16626 were already external.
16628 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

16636 Mark functions with DEFUE instead of DEFUN,
16637 if they are used in other modules.
16638 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
16639 decls for now-static functions.
16640 * buffer.h (Fdelete_overlay): Remove decl.
16641 * callproc.c (Fgetenv_internal): Mark as internal.

16650 * image.c (Finit_image_library): New forward static decl.
16651 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
16652 * intervals.h (Fprevious_property_change):
16653 (Fremove_list_of_text_properties): Remove decls.
16654 * keyboard.c (Fthis_command_keys): Remove decl.
16655 (Fcommand_execute): New forward static decl.

16671 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
16673 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
16676 2011-04-13 Eli Zaretskii <eliz@gnu.org>
16678 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
16679 when at ZV. (Bug#8487)
16681 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
16683 * charset.c (Fclear_charset_maps): Use xfree instead of free.

16686 * sound.c (sound_cleanup, alsa_close): Likewise.
16687 * termcap.c (tgetent): Likewise.
16688 * xfns.c (x_default_font_parameter): Likewise.
16689 * xsettings.c (read_and_apply_settings): Likewise.
16691 * alloc.c (overrun_check_malloc, overrun_check_realloc)
16692 (overrun_check_free): Protoize.
16694 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
16696 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
16697 since callers should never pass a negative size.
16698 Change the signature to match that of plain 'read' and 'write'; see
16699 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
16700 * lisp.h: Update prototypes of emacs_write and emacs_read.
16702 2011-04-11 Eli Zaretskii <eliz@gnu.org>
16704 * xdisp.c (redisplay_window): Don't try to determine the character
16705 position of the scroll margin if the window start point w->startp
16706 is outside the buffer's accessible region. (Bug#8468)
16708 2011-04-10 Eli Zaretskii <eliz@gnu.org>
16710 Fix write-region and its subroutines for buffers > 2GB.
16711 * fileio.c (a_write, e_write): Modify declaration of arguments and
16712 local variables to support buffers larger than 2GB.
16713 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
16715 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
16716 argument, local variables, and return value.
16718 * lisp.h: Update prototypes of emacs_write and emacs_read.
16720 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
16722 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
16724 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
16726 Fix more problems found by GCC 4.6.0's static checks.
16728 * xdisp.c (vmessage): Use a better test for character truncation.
16730 * charset.c (load_charset_map): <, not <=, for optimization,
16731 and to avoid potential problems with integer overflow.
16732 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
16733 * casetab.c (set_identity, shuffle): Likewise.
16734 * editfns.c (Fformat): Likewise.
16735 * syntax.c (skip_chars): Likewise.
16737 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
16738 This also lets GCC 4.6.0 generate slightly better loop code.
16740 * callint.c (Fcall_interactively): <, not <=, for optimization.
16741 (Fcall_interactively): Count the number of arguments produced,
16742 not the number of arguments given. This is simpler and lets GCC
16743 4.6.0 generate slightly better code.
16745 * ftfont.c: Distingish more carefully between FcChar8 and char.
16746 The previous code passed unsigned char * to a functions like
16747 strlen and xstrcasecmp that expect char *, which does not
16748 conform to the C standard.
16749 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
16750 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
16751 char * when the C standard requires it.
16753 * keyboard.c (read_char): Remove unused var.
16755 * eval.c: Port to Windows vsnprintf (Bug#8435).
16756 Include <limits.h>.
16757 (SIZE_MAX): Define if the headers do not.
16758 (verror): Do not give up if vsnprintf returns a negative count.
16759 Instead, grow the buffer. This ports to Windows vsnprintf, which
16760 does not conform to C99. Problem reported by Eli Zaretskii.
16761 Also, simplify the allocation scheme, by avoiding the need for
16762 calling realloc, and removing the ALLOCATED variable.
16764 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
16766 Remove invocations of doprnt, as Emacs now uses vsnprintf.
16767 But keep the doprint source code for now, as we might revamp it
16768 and use it again (Bug#8435).
16769 * lisp.h (doprnt): Remove.
16770 * Makefile.in (base_obj): Remove doprnt.o.
16771 * deps.mk (doprnt.o): Remove.
16773 error: Print 32- and 64-bit integers portably (Bug#8435).
16774 Without this change, on typical 64-bit hosts error ("...%d...", N)
16775 was used to print both 32- and 64-bit integers N, which relied on
16776 undefined behavior.
16777 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
16778 * lisp.h (error, verror): Mark as printf-like functions.
16779 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
16780 Report overflow in size calculations when allocating printf buffer.
16781 Do not truncate output string at its first null byte.
16782 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
16783 Truncate the output at a character boundary, since vsnprintf does not
16785 * charset.c (check_iso_charset_parameter): Convert internal
16786 character to string before calling 'error', since %c now has the
16788 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
16789 overflow when computing char to be passed to 'error'. Do not
16790 pass Lisp_Object to 'error'; pass the integer instead.
16791 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
16792 formatted with plain %d.
16794 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
16796 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
16798 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
16800 * xterm.c (x_catch_errors): Remove duplicate declaration.
16802 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
16804 * xdisp.c, lisp.h (message_nolog): Remove; unused.
16806 2011-04-10 Jim Meyering <meyering@redhat.com>
16808 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
16809 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
16810 return ssize_t not "int", and use size_t as the buffer length.
16811 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
16812 * gnutls.h: Update declarations.
16813 * process.c (read_process_output): Use ssize_t, to match.
16814 (send_process): Likewise.
16816 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16818 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
16820 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
16822 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
16823 Use unsigned char, to match FcChar8 type definition.
16825 * xterm.c (handle_one_xevent):
16826 * xmenu.c (create_and_show_popup_menu):
16827 * xselect.c (x_decline_selection_request)
16828 (x_reply_selection_request): Avoid type-punned deref of X events.
16830 2011-04-09 Eli Zaretskii <eliz@gnu.org>
16832 Fix some uses of `int' instead of EMACS_INT.
16833 * search.c (string_match_1, fast_string_match)
16834 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
16835 (scan_buffer, find_next_newline_no_quit)
16836 (find_before_next_newline, search_command, Freplace_match)
16837 (Fmatch_data): Make some `int' variables be EMACS_INT.
16839 * xdisp.c (display_count_lines): 3rd argument and return value now
16840 EMACS_INT. All callers changed.
16841 (pint2hrstr): Last argument is now EMACS_INT.
16843 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
16844 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
16845 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

16856 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
16857 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
16859 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
16860 (encode_invocation_designation): Last argument P_NCHARS is now
16862 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
16863 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
16865 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
16868 * ccl.c (Fccl_execute_on_string): Declare some variables
16871 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
16873 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
16875 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
16877 * process.c (Fformat_network_address): Doc fix.
16879 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
16881 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
16883 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
16885 * keyboard.c (read_char): Call Lisp function help-form-show,
16886 instead of using internal_with_output_to_temp_buffer.
16887 (Qhelp_form_show): New var.
16888 (syms_of_keyboard): Use DEFSYM macro.
16890 * print.c (internal_with_output_to_temp_buffer): Function deleted.

16903 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
16905 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
16907 Fix more problems found by GCC 4.6.0's static checks.
16909 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
16911 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
16913 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
16915 * xdisp.c (vmessage): Mark as a printf-like function.
16917 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
16919 * sound.c (sound_warning): Don't crash if arg contains a printf format.
16921 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
16922 printf-like functions.
16923 (tiff_load): Add casts to remove these marks before passing them
16924 to system-supplied API.
16926 * eval.c (Fsignal): Remove excess argument to 'fatal'.
16928 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
16929 This avoids several warnings with gcc -Wstrict-overflow.
16930 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
16931 directly, rather than having caller test rule sign. This avoids
16932 some unnecessary tests.
16933 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
16934 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
16935 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
16937 * xfont.c (xfont_text_extents): Remove var that was set but not used.
16938 (xfont_open): Avoid unnecessary tests.
16940 * composite.c (composition_gstring_put_cache): Use unsigned integer.
16942 * composite.h, composite.c (composition_gstring_put_cache):
16943 Use EMACS_INT, not int, for length.
16945 * composite.h (COMPOSITION_DECODE_REFS): New macro,
16946 breaking out part of COMPOSITION_DECODE_RULE.
16947 (COMPOSITION_DECODE_RULE): Use it.
16948 * composite.c (get_composition_id): Remove unused local vars,
16949 by using the new macro.
16951 * textprop.c (set_text_properties_1): Change while to do-while,
16952 since the condition is always true at first.
16954 * intervals.c (graft_intervals_into_buffer): Mark var as used.
16955 (interval_deletion_adjustment): Return unsigned value.
16958 * process.c (list_processes_1, create_pty, read_process_output):
16959 (exec_sentinel): Remove vars that were set but not used.
16960 (create_pty): Remove unnecessary "volatile"s.
16961 (Fnetwork_interface_info): Avoid possibility of int overflow.
16962 (read_process_output): Do adaptive read buffering even if carryover.
16963 (read_process_output): Simplify nbytes computation if buffered.
16965 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
16967 * syntax.c (scan_words): Remove var that was set but not used.
16968 (update_syntax_table): Use unsigned instead of int.
16970 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
16971 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
16972 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
16974 * print.c (print_error_message): Avoid int overflow.
16976 * font.c (font_list_entities): Redo for clarity,
16977 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
16979 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
16980 (font_score): Avoid potential overflow in diff calculation.
16982 * fns.c (substring_both): Remove var that is set but not used.
16983 (sxhash): Redo loop for clarity and to avoid wraparound warning.
16985 * eval.c (funcall_lambda): Rename local to avoid shadowing.
16987 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
16988 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
16989 can always succeed if overflow has undefined behavior.
16991 * search.c (boyer_moore, wordify): Remove vars set but not used.
16992 (wordify): Omit three unnecessary tests.
16994 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
16995 All callers changed. This avoids the need for an unused var.
16997 * casefiddle.c (casify_region): Remove var that is set but not used.
16999 * dired.c (file_name_completion): Remove var that is set but not used.
17001 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
17003 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
17004 (Finsert_file_contents): Remove unnecessary code checking fd.
17006 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
17007 Check for integer overflow on size calculations.
17009 * buffer.c (Fprevious_overlay_change): Remove var that is set
17012 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
17013 Remove vars that are set but not used.
17014 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
17015 (timer_check_2): Mark vars as initialized.
17017 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
17019 * image.c (lookup_image): Remove var that is set but not used.
17020 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
17022 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
17023 that are set but not used.
17025 * xfns.c (make_invisible_cursor): Don't return garbage
17026 if XCreateBitmapFromData fails (Bug#8410).
17028 * xselect.c (x_get_local_selection, x_handle_property_notify):
17029 Remove vars that are set but not used.
17031 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
17032 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
17034 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
17035 Remove var that is set but not used.
17036 (scroll_bar_windows_size): Now size_t, not int.
17037 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
17038 Check for overflow.
17040 * xfaces.c (realize_named_face): Remove vars that are set but not used.
17041 (map_tty_color) [!defined MSDOS]: Likewise.
17043 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
17045 * coding.c: Remove vars that are set but not used.
17046 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
17047 All callers changed.
17048 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
17049 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
17050 (decode_coding_charset): Remove vars that are set but not used.
17052 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
17053 that is set but not used.
17055 * print.c (print_object): Remove var that is set but not used.
17057 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
17058 The gnulib version avoids calling malloc in the usual case,
17059 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
17060 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
17061 * filelock.c (current_lock_owner): Likewise.
17062 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
17063 * sysdep.c: Include allocator.h, careadlinkat.h.
17064 (emacs_no_realloc_allocator): New static constant.
17065 (emacs_readlink): New function.
17066 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
17067 ../lib/careadlinkat.h.
17069 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
17071 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
17072 first non-nil return value).
17074 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
17076 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
17077 if not defined (Bug#8403).
17079 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
17081 * xdisp.c (display_count_lines): Remove parameter `start',
17082 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
17083 (get_char_face_and_encoding): Remove parameter `multibyte_p',
17084 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

17086 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
17087 and thereabouts. All callers changed.
17088 (get_per_char_metric): Remove parameter `f', unused since
17089 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
17091 2011-04-02 Jim Meyering <meyering@redhat.com>
17093 do not dereference NULL upon failed strdup
17094 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
17095 (ns_get_family): Likewise.
17097 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
17099 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
17101 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
17103 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
17106 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
17108 Add lexical binding.
17110 * window.c (Ftemp_output_buffer_show): New fun.
17111 (Fsave_window_excursion):
17112 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
17114 * lread.c (lisp_file_lexically_bound_p): New function.
17115 (Fload): Bind Qlexical_binding.
17116 (readevalloop): Remove `evalfun' arg.
17117 Bind Qinternal_interpreter_environment.
17118 (Feval_buffer): Bind Qlexical_binding.
17119 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
17121 (syms_of_lread): Declare `lexical-binding'.
17123 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
17125 * keyboard.c (eval_dyn): New fun.
17126 (menu_item_eval_property): Use it.
17128 * image.c (parse_image_spec): Use Ffunctionp.
17130 * fns.c (concat, mapcar1): Accept byte-code-functions.
17132 * eval.c (Fsetq): Handle lexical vars.
17133 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
17134 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
17135 (FletX, Flet): Obey lexical binding.
17136 (Fcommandp): Handle closures.
17137 (Feval): New `lexical' arg.
17138 (eval_sub): New function extracted from Feval. Use it almost
17139 everywhere where Feval was used. Look up vars in lexical env.
17141 (Ffunctionp): Move from subr.el.
17142 (Ffuncall): Handle closures.
17143 (apply_lambda): Remove `eval_flags'.
17144 (funcall_lambda): Handle closures and new byte-code-functions.
17145 (Fspecial_variable_p): New function.
17146 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
17147 but without exporting it to Lisp.
17149 * doc.c (Fdocumentation, store_function_docstring):
17150 * data.c (Finteractive_form): Handle closures.
17152 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
17155 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
17157 (exec_byte_code): New function extracted from Fbyte_code to handle new
17158 calling convention for byte-code-functions. Add new byte-codes.
17160 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
17162 * alloc.c (Fmake_symbol): Init new `declared_special' field.
17164 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
17166 * xdisp.c (redisplay_internal): Fix prototype.
17168 2011-03-31 Eli Zaretskii <eliz@gnu.org>
17170 * xdisp.c (SCROLL_LIMIT): New macro.
17171 (try_scrolling): Use it when setting scroll_limit.
17172 Limit scrolling to 100 screen lines.
17173 (redisplay_window): Even when falling back on "recentering",
17174 position point in the window according to scroll-conservatively,
17175 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
17177 (try_scrolling): When point is above the window, allow searching
17178 as far as scroll_max, or one screenful, to compute vertical
17179 distance from PT to the scroll margin position. This prevents
17180 try_scrolling from unnecessarily failing when
17181 scroll-conservatively is set to a value slightly larger than the
17182 window height. Clean up the case of PT below the margin at bottom
17183 of window: scroll_max can no longer be INT_MAX. When aggressive
17184 scrolling is in use, don't let point enter the opposite scroll
17185 margin as result of the scroll.
17186 (syms_of_xdisp) <scroll-conservatively>: Document the
17187 threshold of 100 lines for never-recentering scrolling.
17189 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
17191 * dispextern.h (move_it_by_lines):
17192 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
17193 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
17194 (message_log_check_duplicate): Remove parameters `prev_bol' and
17195 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
17196 (redisplay_internal): Remove parameter `preserve_echo_area',
17197 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
17199 * indent.c (Fvertical_motion):
17200 * window.c (window_scroll_pixel_based, Frecenter):
17201 Don't pass `need_y_p' to `move_it_by_lines'.
17203 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
17205 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
17206 steal a few bits to be more compact.
17207 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
17208 Remove unneeded casts.
17210 * bytecode.c (Fbyte_code): CAR and CDR can GC.
17212 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
17214 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
17215 binding" message (bug#7967).
17217 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
17219 Fix more problems found by GCC 4.6.0's static checks.
17221 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
17222 Remove unused local var.
17224 * editfns.c (Fmessage_box): Remove unused local var.
17226 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
17227 (note_mode_line_or_margin_highlight, note_mouse_highlight):
17228 Omit unused local vars.
17229 * window.c (shrink_windows): Omit unused local var.
17230 * menu.c (digest_single_submenu): Omit unused local var.
17231 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
17232 Omit unused local var.
17234 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
17235 Don't assume string length fits in int.
17236 (keyremap_step, read_key_sequence): Use size_t for sizes.
17237 (read_key_sequence): Don't check last_real_key_start redundantly.
17239 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
17240 instead of alloca (Bug#8344).
17242 * eval.c (Fbacktrace): Don't assume nargs fits in int.
17243 (Fbacktrace_frame): Don't assume nframes fits in int.
17245 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
17247 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
17250 * term.c (produce_glyphless_glyph): Remove unnecessary test.
17252 * cm.c (calccost): Turn while-do into do-while, for clarity.
17254 * keyboard.c (syms_of_keyboard): Use the same style as later
17255 in this function when indexing through an array. This also
17256 works around GCC bug 48267.
17258 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
17260 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
17262 * chartab.c (sub_char_table_ref_and_range): Redo for slight
17263 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
17265 * keyboard.c, keyboard.h (num_input_events): Now size_t.
17266 This avoids undefined behavior on integer overflow, and is a bit
17267 more convenient anyway since it is compared to a size_t variable.
17269 Variadic C functions now count arguments with size_t, not int.
17270 This avoids an unnecessary limitation on 64-bit machines, which
17271 caused (substring ...) to crash on large vectors (Bug#8344).
17272 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
17273 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

17281 * fns.c (concat): Likewise.
17282 * frame.c (x_set_frame_parameters): Likewise.
17283 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
17284 0 if not found, not -1. All callers changed.
17286 * alloc.c (garbage_collect): Don't assume stack size fits in int.
17287 (stack_copy_size): Now size_t, not int.
17288 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
17290 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
17292 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
17293 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
17294 All callers changed.
17296 * lisp.h (multibyte_char_to_unibyte):
17297 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
17298 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

17302 * keymap.c (push_key_description):
17303 * search.c (Freplace_match):
17304 * xdisp.c (message_dolog, set_message_1): All callers changed.
17306 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
17308 * keyboard.c (safe_run_hook_funcall): New function.
17309 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
17310 don't set the hook to nil, but remove the offending function instead.
17311 (Qcommand_hook_internal): Remove, unused.
17312 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
17313 Vcommand_hook_internal.
17315 * eval.c (enum run_hooks_condition): Remove.
17316 (funcall_nil, funcall_not): New functions.
17317 (run_hook_with_args): Call each function through a `funcall' argument.
17318 Remove `cond' argument, now redundant.
17319 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
17320 (Frun_hook_with_args_until_failure): Adjust accordingly.
17321 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

17327 * print.c (strout): Remove parameter `multibyte', unused since
17328 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
17330 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
17331 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
17332 All callers changed.
17334 * w32.c (_wsa_errlist): Use braces for struct initializers.
17336 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
17337 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
17338 All callers changed.

17501 Fix more problems found by GCC 4.5.2's static checks.
17503 * coding.c (encode_coding_raw_text): Avoid unnecessary test
17504 the first time through the loop, since we know p0 < p1 then.
17505 This also avoids a gcc -Wstrict-overflow warning.
17507 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
17508 leading to a memory leak, possible in functions like
17509 load_charset_map_from_file that can allocate an unbounded number
17510 of objects (Bug#8318).
17512 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
17513 that could (at least in theory) be that large.
17515 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
17516 This is less likely to overflow, and avoids undefined behavior if
17517 overflow does occur. All callers changed. Use strtoul to scan
17518 for the unsigned long integer.
17519 (pint2hrstr): Simplify and tune code slightly.
17520 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

17535 * process.c (Fmake_network_process): Use socklen_t, not int,
17536 where POSIX says socklen_t is required in portable programs.
17537 This fixes a porting bug on hosts like 64-bit HP-UX, where
17538 socklen_t is wider than int (Bug#8277).
17539 (Fmake_network_process, server_accept_connection):
17540 (wait_reading_process_output, read_process_output):
17543 * process.c: Rename or move locals to avoid shadowing.

17553 Make tparam.h and terminfo.c consistent.
17554 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
17555 Include tparam.h instead, since it declares them.
17556 * cm.h (PC): Remove extern decl; tparam.h now does this.
17557 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
17558 * terminfo.c: Include tparam.h, to check interfaces.
17559 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
17560 (tparam): Adjust signature to match interface in tparam.h;
17561 this removes some undefined behavior. Check that outstring and len
17562 are zero, which they always are with Emacs.
17563 * tparam.h (PC, BC, UP): New extern decls.
17565 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
17566 (xftfont_open): Rename locals to avoid shadowing.

17580 * composite.c (composition_compute_stop_pos): Rename local to
17582 (composition_reseat_it): Remove unused locals.
17583 (find_automatic_composition, composition_adjust_point): Likewise.
17584 (composition_update_it): Mark var as initialized.
17585 (find_automatic_composition): Mark vars as initialized,
17586 with a FIXME (Bug#8290).

17590 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
17591 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
17592 (BUF_DEC_POS): Be more systematic about renaming local temporaries
17593 to avoid shadowing.
17595 * textprop.c (property_change_between_p): Remove; unused.
17597 * intervals.c (interval_start_pos): Now static.
17599 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

17605 Fix pointer signedness.
17606 (alsa_choose_format): Remove unused local var.
17607 (wav_play): Initialize a variable to 0, to prevent undefined
17608 behavior (Bug#8278).
17610 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
17612 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
17614 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
17615 clobbering (Bug#8298).
17616 * sysdep.c (sys_subshell): Likewise.
17617 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
17619 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
17620 This should get cleaned up, so that child_setup has the
17621 same signature on all platforms.
17623 * callproc.c (call_process_cleanup): Now static.
17624 (relocate_fd): Rename locals to avoid shadowing.
17626 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
17628 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
17629 not to be necessary, and produces flickering.
17631 2011-03-20 Glenn Morris <rgm@gnu.org>
17633 * config.in: Remove file.
17635 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
17637 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
17638 are now in src/globals.h.
17639 (syms_of_minibuf): Remove spurious & from previous change.
17641 2011-03-20 Leo Liu <sdl.web@gmail.com>
17643 * minibuf.c (completing-read-function): New variable.
17644 (completing-read-default): Rename from completing-read.
17645 (completing-read): Call completing-read-function.

17654 * makefile.w32-in: Update dependencies.
17656 2011-03-17 Eli Zaretskii <eliz@gnu.org>
17658 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

17679 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
17680 Define only if needed.
17682 * unexelf.c (unexec): Name an expression,
17683 to avoid gcc -Wbad-function-cast warning.
17684 Use a different way to cause a compilation error if anyone uses
17685 n rather than nn, a way that does not involve shadowing.
17686 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
17688 * deps.mk (unexalpha.o): Remove; unused.
17690 New file unexec.h, the (simple) interface for unexec (Bug#8267).

17799 (uppercasep, lowercasep, upcase): New static inline functions.
17800 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

17809 which gcc can warn about.
17810 (regex_compile, re_match_2_internal): Mark locals as initialized.
17811 (RETALLOC_IF): Define only if needed.
17812 (WORDCHAR_P): Likewise. This one is never needed, but is used
17813 only in a comment talking about a compiler bug, so put inside
17814 the #if 0 of that comment.
17815 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
17816 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

17844 gcpro1, gcpro2, etc.
17845 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
17847 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
17848 argument, for consistency with GCPRO2_VAR, etc: it is now the

17852 Rename locals to avoid shadowing.
17854 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).

17858 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
17859 * buffer.h: ... to here, because these macros use current_buffer,
17860 and the new implementation with inline functions needs to have
17861 current_buffer in scope now, rather than later when the macros
17863 (downcase, upcase1): New static inline functions.
17864 (DOWNCASE, UPCASE1): Reimplement using these functions.
17865 This avoids undefined behavior in expressions like
17866 DOWNCASE (x) == DOWNCASE (y), which previously suffered
17867 from race conditions in accessing the global variables
17868 case_temp1 and case_temp2.
17869 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.

17886 (Fset_file_times, Finsert_file_contents, auto_save_error):

17891 to avoid shadowing.
17893 * marker.c (bytepos_to_charpos): Remove; unused.
17895 * lisp.h (verify_bytepos, count_markers): New decls,
17896 so that gcc does not warn that these functions aren't declared.

17899 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

17906 * buffer.c (fix_overlays_before): Mark locals as initialized.
17907 (fix_start_end_in_overlays): Likewise. This function should be
17908 simplified by using pointers-to-pointers, but that's a different

17911 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
17912 (report_overlay_modification): Rename locals to avoid shadowing.

17917 to suppress a gcc -Wclobbered warning that does not seem to be right.
17918 (MAXPATHLEN): Define only if needed.
17920 * process.c (serial_open, serial_configure): Move decls from here ...
17921 * systty.h: ... to here, so that they can be checked.
17923 * fns.c (get_random, seed_random): Move extern decls from here ...
17924 * lisp.h: ... to here, so that they can be checked.
17926 * sysdep.c (reset_io): Now static.
17927 (wait_for_termination_signal): Remove; unused.
