90 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
91 for some of that bug's symptoms can now cause Emacs to abort.
92 Remove the workaround.
93 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.

181 * fileio.c (Finsert_file_contents): Don't put tail into head area,
182 as that confuses set-auto-coding, so insist on the head-read

213 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
214 fstat shouldn't fail, and if it does fail copy-file should not proceed.
215 Remove unnecessary S_ISLNK test, as (contra the comments) this
216 function can't copy symlinks. Improve quality of error message
217 when attempting to copy files that are neither regular files nor

242 it->start_of_box_run_p.
243 (append_space_for_newline): If the glyph row is R2L, reset the
244 iterator's end_of_box_run_p flag before prepending the space glyph.
245 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
246 iterator's start_of_box_run_p flag before prepending the stretch.

502 (Fsignal_process): Use it to convert signal names to ints.
503 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
504 kill (getpgrp (), ...).
505 (emacs_sigaction_init): Assume SIGCHLD is defined.
506 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
507 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
508 * syssignal.h (EMACS_KILLPG): Remove.
509 All uses replaced by 'kill' with a negative pid.
510 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
511 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
513 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
515 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
516 This will cause a production Emacs to dump core instead of
519 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
521 * frame.c (make_frame): Do not set window's buffer to t.
522 * window.c (Fsplit_window_internal): Likewise. Previously it was
523 used to indicate that the window is being set up. Now we use
524 set_window_buffer for all new windows, so the condition in ...
525 (Fset_window_buffer): ... is always true and can be removed.
527 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
529 Convenient macro to check whether the buffer is hidden.
530 * buffer.h (BUFFER_HIDDEN_P): New macro.
531 * frame.c (make_frame): Use it. Adjust comment.
532 * buffer.c (candidate_buffer): New function.
533 (Fother_buffer, other_buffer_safely): Use it.
535 2012-12-06 Eli Zaretskii <eliz@gnu.org>
537 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
538 if the child process is still running. Instead, exit the wait
539 loop and return zero. (Bug#13086)
541 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
543 * frame.h (x_char_width, x_char_height): Remove prototypes.

550 (Fframe_char_height): Likewise with FRAME_LINE_HEIGHT.
551 * keyboard.c (command_loop_1): Remove prototype.
552 (command_loop_2, top_level_1): Add static to match prototype.
554 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
556 Fix a recently-introduced delete-process race condition.
557 * callproc.c, process.h (record_kill_process):
558 New function, containing part of the old call_process_kill.
559 (call_process_kill): Use it.
560 This does not change call_process_kill's behavior.
561 * process.c (Fdelete_process): Use record_kill_process to fix a
562 race condition that could cause Emacs to lose track of a child.
564 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
566 Avoid code duplication between prev_frame and next_frame.
567 * frame.c (candidate_frame): New function. Add comment.
568 (prev_frame, next_frame): Use it. Adjust comment.
570 2012-12-06 Eli Zaretskii <eliz@gnu.org>
572 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
573 fails, signal an error instead of continuing with an empty
575 Encode expanded temp file pattern before passing it to mkstemp or
578 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
579 Encode the file name before passing it to dostounix_filename, in
580 case it will downcase it (under w32-downcase-file-names).
583 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
585 Minor call-process cleanups.
586 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
587 at the same time as other platforms, to simplify analysis.
588 No need for fd0_volatile since we have synch_process_fd.
589 Avoid needless emacs_close; arg is always negative.
591 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
593 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
596 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
598 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
599 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
600 and mouse_face_hidden members to a bitfields.
601 * frame.h (struct frame): Remove set-but-not-used space_width member.
602 (FRAME_SPACE_WIDTH): Remove.
603 * nsterm.m, w32term.c, xterm.c: Adjust users.
604 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
605 member. Adjust users. Convert term_initted, delete_in_insert_mode,
606 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
607 members to a bitfields.
609 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
611 Don't let call-process be a zombie factory (Bug#12980).
612 Fixing this bug required some cleanup of the signal-handling code.
613 As a side effect, this change also fixes a longstanding rare race
614 condition whereby Emacs could mistakenly kill unrelated processes,
615 and it fixes a bug where a second C-g does not kill a recalcitrant
616 synchronous process in GNU/Linux and similar platforms.
617 The patch should also fix the last vestiges of Bug#9488,
618 a bug which has mostly been fixed on the trunk by other changes.
619 * callproc.c, process.h (synch_process_alive, synch_process_death)
620 (synch_process_termsig, sync_process_retcode):
621 Remove. All uses removed, to simplify analysis and so that
622 less consing is done inside critical sections.
623 * callproc.c (call_process_exited): Remove. All uses replaced
624 with !synch_process_pid.
625 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
626 These take the role of what used to be in unwind-protect arg.
628 (block_child_signal, unblock_child_signal):
629 New functions, to avoid races that could kill innocent-victim processes.
630 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
631 (call_process_kill): Record killed processes as deleted, so that
632 zombies do not clutter up the system. Do this inside a critical
633 section, to avoid a race that would allow the clutter.
634 (call_process_cleanup): Fix code so that the second C-g works again
635 on common platforms such as GNU/Linux.
636 (Fcall_process): Create the child process in a critical section,
637 to fix a race condition. If creating an asynchronous process,
638 record it as deleted so that zombies do not clutter up the system.
639 Do unwind-protect for WINDOWSNT too, as that's simpler in the
640 light of these changes. Omit unnecessary call to emacs_close
641 before failure, as the unwind-protect code does that.
642 * callproc.c (call_process_cleanup):
643 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
644 * process.c (record_deleted_pid): New function, containing
645 code refactored out of Fdelete_process.
646 (Fdelete_process): Use it.
647 (process_status_retrieved): Remove. All callers changed to use
649 (record_child_status_change): Remove, folding its contents into ...
650 (handle_child_signal): ... this signal handler. Now, this
651 function is purely a handler for SIGCHLD, and is not called after
652 a synchronous waitpid returns; the synchronous code is moved to
653 wait_for_termination. There is no need to worry about reaping
654 more than one child now.
655 * sysdep.c (get_child_status, child_status_changed): New functions.
656 (wait_for_termination): Now takes int * status and bool
657 interruptible arguments, too. Do not record child status change;
658 that's now the caller's responsibility. All callers changed.
659 Reimplement in terms of get_child_status.
660 (wait_for_termination_1, interruptible_wait_for_termination):
661 Remove. All callers changed to use wait_for_termination.
662 * syswait.h: Include <stdbool.h>, for bool.
663 (record_child_status_change, interruptible_wait_for_termination):
665 (record_deleted_pid, child_status_changed): New decls.
666 (wait_for_termination): Adjust to API changes noted above.
668 * bytecode.c, lisp.h (Qbytecode): Remove.
669 No longer needed after 2012-11-20 interactive-p changes.
671 2012-12-03 Eli Zaretskii <eliz@gnu.org>
673 * xdisp.c (redisplay_window): If the cursor is visible, but inside
674 the scroll margin, move point outside the margin. (Bug#13055)
676 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
678 * gtkutil.c (my_log_handler): New function.
679 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
681 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
683 * lisp.h (modify_region): Rename to...
684 (modify_region_1): ...new prototype.
685 * textprop.c (modify_region): Now static. Adjust users.
686 * insdel.c (modify_region): Rename to...
687 (modify_region_1): ...new function to work with current buffer.
688 Adjust comment and users. Use true and false for booleans.
690 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
692 * alloc.c (free_save_value): New function.
693 (safe_alloca_unwind): Use it.
694 * lisp.h (free_save_value): New prototype.
695 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
697 (save_excursion_restore): Adjust to match saved data structure.
698 Use free_save_value to offload some work from GC. Drop obsolete
701 2012-12-03 Chong Yidong <cyd@gnu.org>
703 * fileio.c (Vauto_save_list_file_name): Doc fix.
705 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
707 * w32fns.c: Remove prototype of atof.
708 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
710 (file_dialog_callback): Make it UINT_PTR.
712 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
715 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
716 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
719 2012-12-03 Glenn Morris <rgm@gnu.org>
721 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
723 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
725 Fix xpalloc confusion after memory is exhausted.
726 * alloc.c (xpalloc): Comment fix.
727 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
728 and signals an error, do not clear charset_table_size, as
729 charset_table is still valid.
730 * doprnt.c (evxprintf): Clear *BUF after freeing it.
732 Use execve to avoid need to munge environ (Bug#13054).
733 * callproc.c (Fcall_process):
734 * process.c (create_process):
735 Don't save and restore environ; no longer needed.
736 * callproc.c (child_setup):
737 Use execve, not execvp, to preserve environ.
739 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
741 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
743 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
745 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
746 display for sliced images (Bug#10500).
748 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
750 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
752 * doc.c (Fdocumentation): Re-add handling of function-documentation,
753 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
755 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
757 * xdisp.c (window_outdated): Remove eassert since it hits
758 some suspicious corner cases (see Bug#13007 and Bug#13012).
759 (mode_line_update_needed): New function.
760 (redisplay_internal, redisplay_window): Use it.
761 (ensure_selected_frame): New function.
762 (redisplay_internal, unwind_redisplay): Use it.
763 (redisplay_internal): Move comment about buffer_shared...
764 (buffer_shared_and_changed): ...near to its real use.
766 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
768 * callproc.c (Fcall_process): Don't misreport vfork failure.
770 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
772 * callproc.c (Fcall_process): Fix vfork portability problems.
773 Do not assume that fd[0], count, filefd, and save_environ survive
774 vfork. Fix bug whereby wrong errno value could be reported for
775 pipe failure. Some minor cleanups, too, as follows. Move buf and
776 bufsize to the context where they're needed. Change new_argv to
777 be of type char **, as this is more convenient and avoids casts.
778 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
779 Now local constants, not macros.
781 2012-11-18 Kenichi Handa <handa@gnu.org>
783 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
784 for the variable "f".
786 2012-11-13 Kenichi Handa <handa@gnu.org>
788 * font.c (font_unparse_xlfd): Exclude special characters from the
789 generating XLFD name.
791 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

806 Assume EIO and EAGAIN are defined.
807 * unexcoff.c (write_segment): Assume EFAULT is defined.
809 2012-11-27 Eli Zaretskii <eliz@gnu.org>
811 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
814 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
815 highlighting on the frame was cleared. Prevents assertion
816 violations when repeatedly clicking on the "Top" link of the
817 "bread-crumbs" in Info buffers.

831 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
832 between bpos_covered and bpos_max. This fixes cursor display when
833 several display strings follow each other.
835 * .gdbinit (pgx): If the glyph's object is a string, display the
836 pointer to string data, rather than the value of the string object
837 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
839 * indent.c (Fvertical_motion): If the starting position is covered
840 by a display string, return to one position before that, to avoid
841 overshooting it inside move_it_to. (Bug#12930)
843 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>

853 asked_for_visible and menubar_active members.
854 Drop unused pending_menu_activation member.
855 * xterm.h (struct x_output): Drop outdated #if 0 code.
856 Use bitfields for explicit_parent, asked_for_visible,
857 has_been_visible and net_wm_state_hidden_seen members.
859 2012-11-23 Eli Zaretskii <eliz@gnu.org>

862 of a literal "/". (Bug#12955)
863 (gl-stamp): Invoke fc.exe directly, not through cmd.
865 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>

869 (NAMLEN): Remove, replacing with ...
870 (dirent_namelen): New function. All uses changed. Use the GNU macro
871 _D_EXACT_NAMELEN if available, as it's faster than strlen.
872 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
873 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
874 * makefile.w32-in (DIR_H): Remove. All uses replaced with
876 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
877 * ndir.h: Rename to ../nt/inc/dirent.h.
878 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
879 Do not include <dirent.h>; no longer needed.
880 * w32.c: Include <dirent.h> rather than "ndir.h".
882 2012-11-23 Chong Yidong <cyd@gnu.org>
884 * xftfont.c (xftfont_open): Remove duplicate assignment.
886 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
888 * alloc.c (Fgarbage_collect): Unblock input after clearing
889 gc_in_progress to avoid note_mouse_highlight glitch with GC.
890 * frame.h (FRAME_MOUSE_UPDATE): New macro.
891 * msdos.c (IT_frame_up_to_date): Use it here...
892 * w32term.c (w32_frame_up_to_date): ...here...
893 * xterm.c (XTframe_up_to_date): ...and here...
894 * nsterm.m (ns_frame_up_to_date): ...but not here.
895 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
897 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
898 Do not check whether GC is in progress.

902 * xdisp.c (window_buffer_changed): New function.
903 (update_menu_bar, update_tool_bar): Use it to
904 simplify large 'if' statements.
905 (redisplay_internal): Generalize commonly used
906 'tail' and 'frame' local variables.
908 2012-11-22 Eli Zaretskii <eliz@gnu.org>
910 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
911 with Windows system header.
913 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
915 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
916 * alloc.c: Assume unistd.h exists.
917 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
918 * sysdep.c (get_current_dir_name): Assume getcwd exists.
919 (getwd) [USG]: Remove; no longer needed.

936 2012-11-21 Eli Zaretskii <eliz@gnu.org>
938 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
939 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
940 Define for the MSVC compiler.
942 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
944 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
945 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
946 dostounix_filename. Prevents crashes down the road, because
947 dostounix_filename assumes it gets a unibyte string.

980 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
981 (syms_of_eval): Remove corresponding defsubr.
982 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
984 2012-11-19 Daniel Colascione <dancol@dancol.org>
986 * w32fns.c (Fx_file_dialog):
987 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
988 cygwin_convert_file_name*.
990 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
991 Rename cygwin_convert_path* to cygwin_convert_file_name*.
993 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
995 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
997 2012-11-18 Eli Zaretskii <eliz@gnu.org>
999 * w32select.c: Include w32common.h before w32term.h, so that
1000 windows.h gets included before w32term.h uses some of its
1001 features, see below.
1003 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
1005 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
1007 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
1009 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
1011 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
1012 (ns_select): Return at once if events are held (Bug#12834).
1014 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
1016 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
1017 Needed following 2012-10-20 change. (Bug#12902)
1019 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
1021 * w32proc.c (waitpid): Remove unused label get_result.
1023 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
1025 * makefile.w32-in (SYSWAIT_H): New macro.
1026 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
1027 ($(BLD)/sysdep.$(O)): Update dependencies.
1029 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1031 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
1032 * callproc.c (relocate_fd): Assume F_DUPFD.
1033 * emacs.c, term.c (O_RDWR): Remove.
1034 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
1035 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
1036 * nsterm.m: Assume <fcntl.h> exists.
1037 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
1038 (create_pty, Fmake_network_process, server_accept_connection)
1039 (wait_reading_process_output, init_process_emacs):
1041 (wait_reading_process_output): Put in a special case for WINDOWSNT
1042 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
1043 It's not clear this is needed, but it's a more-conservative change.
1044 (create_process): Assume FD_CLOEXEC.
1045 (create_process, create_pty): Assume O_NOCTTY.
1046 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
1047 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
1048 Omit if not DOS_NT, since F_GETFL is not defined there.
1049 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
1050 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1052 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1053 lack it, since gnulib guarantees this.
1054 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1056 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1058 * w32.c (faccessat): Pretend that directories have the execute bit
1059 set. Emacs expects that, e.g., in files.el:cd-absolute.
1061 * w32proc.c (create_child): Don't clip the PID of the child
1062 process to fit into an Emacs integer, as this is no longer a
1064 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1065 reaping only the process specified by PID argument, if that is
1066 positive. Use PID instead of dead_child to know which process to
1067 reap. Wait for the child to die only if WNOHANG is not in
1069 (sys_select): Don't set dead_child.
1071 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1072 as it is no longer needed.
1074 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1076 (record_child_status_change): Remove the setting of
1077 record_at_most_one_child for the !WNOHANG case.
1079 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1081 Fix problems in ns port found by static checking.
1082 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1083 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1084 not to process group.
1085 (ns_select): Use emacs_write, not write, as that's more robust
1086 in the presence of signals.
1087 (fd_handler:): Check for read errors.
1089 2012-11-16 Glenn Morris <rgm@gnu.org>
1091 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
1093 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
1095 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
1097 2012-11-16 Eli Zaretskii <eliz@gnu.org>
1099 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1100 use the same value of thread handle.
1101 (start_timer_thread): If the timer thread exited (due to error),
1102 clean up by closing the two handles it used. Duplicate the caller
1103 thread's handle here, so it gets duplicated only once, when
1104 launching the timer thread. Set priority of the timer thread, not
1106 (getitimer): Don't duplicate the caller thread's handle here.
1109 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1111 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1114 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1116 Remove no-longer-used pty_max_bytes variable.
1117 * process.c (pty_max_bytes): Remove; unused.
1118 (send_process): Do not set it.
1120 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1122 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1123 Update dependencies.
1125 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1127 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1128 This follows up on the 2012-09-29 patch that removed indirection
1129 for the 'function' field. Reported by Sergey Vinokurov in
1130 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1132 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1134 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1135 different name, as the MS runtime does not have such a function,
1136 and probably never will.) All callers changed. Ignore DIRFD
1137 value if PATH is an absolute file name, to match Posix spec
1138 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1141 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1143 * xdisp.c (echo_area_display, redisplay_internal):
1144 Omit redundant check whether frame_garbaged is set.
1146 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1148 Use faccessat, not access, when checking file permissions (Bug#12632).
1149 This fixes a bug that has been present in Emacs since its creation.
1150 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1151 which must set some sort of record. (Torek's bug report was against
1152 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1153 same common flaw.) See Torek's Usenet posting
1154 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1155 Posted: Fri Apr 8 14:18:56 1983.
1156 * Makefile.in (LIB_EACCESS): New macro.
1158 * callproc.c (init_callproc):
1159 * charset.c (init_charset):
1160 * fileio.c (check_existing, check_executable, check_writable)
1162 * lread.c (openp, load_path_check):
1163 * process.c (allocate_pty):
1165 Use effective UID when checking permissions, not real UID.
1166 * callproc.c (init_callproc):
1167 * charset.c (init_charset):
1168 * lread.c (load_path_check, init_lread):
1169 Test whether directories are accessible, not merely whether they exist.
1170 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1171 * fileio.c (check_existing, check_executable, check_writable)
1173 Use symbolic names instead of integers for the flags, as they're
1175 (check_writable): New arg AMODE. All uses changed.
1176 Set errno on failure.
1177 (Ffile_readable_p): Use faccessat, not stat + open + close.
1178 (Ffile_writable_p): No need to call check_existing + check_writable.
1179 Just call check_writable and then look at errno. This saves a syscall.
1180 dir should never be nil; replace an unnecessary runtime check
1181 with an eassert. When checking the parent directory of a nonexistent
1182 file, check that the directory is searchable as well as writable, as
1183 we can't create files in unsearchable directories.
1184 (file_directory_p): New function, which uses 'stat' on most platforms
1185 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1186 (Ffile_directory_p, Fset_file_times): Use it.
1187 (file_accessible_directory_p): New function, which uses a single
1188 syscall for efficiency.
1189 (Ffile_accessible_directory_p): Use it.
1190 * xrdb.c (file_p): Use file_directory_p.
1191 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1192 * lread.c (openp): When opening a file, use fstat rather than
1193 stat, as that avoids a permissions race. When not opening a file,
1194 use file_directory_p rather than stat.
1195 (dir_warning): First arg is now a usage string, not a format.
1196 Use errno. All uses changed.
1197 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1198 that merely introduced a race.
1199 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1200 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1201 and similarly for the other O_* flags.
1202 * w32.c (sys_faccessat): Rename from sys_access and switch to
1203 faccessat's API. All uses changed.
1204 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1205 (magic_db): Rename from magic_file_p.
1206 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1207 char *, so that we don't have to test for file existence
1208 separately from opening the file for reading. This removes a race
1209 fixes a permission-checking problem, and simplifies the code.
1211 (file_p): Remove; no longer needed.
1213 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1215 Omit glyphs initialization at startup.
1216 * dispnew.c (glyphs_initialized_initially_p): Remove.
1217 (adjust_frame_glyphs_initially): Likewise. Adjust users.
1218 (Fredraw_frame): Move actual code from here...
1219 (redraw_frame): ...to here. Add eassert. Adjust comment.
1220 (Fredraw_display): Use redraw_frame.
1221 * xdisp.c (clear_garbaged_frames): Likewise.
1223 2012-11-13 Eli Zaretskii <eliz@gnu.org>
1225 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
1226 passed to pint2str and pint2hrstr to be at most the size of the
1227 frame's decode_mode_spec_buffer. This avoids crashes with very
1228 large values of FIELD_WIDTH argument to decode_mode_spec.
1231 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1233 Fix a race with verify-visited-file-modtime (Bug#12863).
1234 Since at least 1991 Emacs has ignored an mtime difference of no
1235 more than one second, but my guess is that this was to work around
1236 file system bugs that were fixed long ago. Since the race is
1237 causing problems now, let's remove that code.
1238 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1239 whose time stamp is off by no more than a second. Insist that the
1240 file time stamps match exactly.
1242 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1244 * frame.h (struct frame): Convert external_tool_bar member to
1245 1-bit unsigned bitfield.
1246 * termhooks.h (struct terminal): Remove mouse_moved member since
1247 all users are long dead. Adjust comment on mouse_position_hook.
1249 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1251 Simplify by using FOR_EACH_FRAME here and there.
1252 * frame.c (next_frame, prev_frame, other_visible_frames)
1253 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
1254 * w32term.c (x_window_to_scroll_bar): Likewise.
1255 * window.c (window_list): Likewise.
1256 * xdisp.c (x_consider_frame_title): Likewise.
1257 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
1258 * xfns.c (x_window_to_frame, x_any_window_to_frame)
1259 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
1260 * xmenu.c (menubar_id_to_frame): Likewise.
1261 * xselect.c (frame_for_x_selection): Likewise.
1262 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1263 (x_window_to_menu_bar): Likewise.
1264 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1266 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1268 * data.c (Qdefalias_fset_function): Now static.
1270 Another tweak to vectorlike_header change.
1271 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
1272 Remove, and replace all uses with ...
1273 (next_in_free_list, set_next_in_free_list):
1274 New functions, which respect C's aliasing rules better.
1276 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1278 * window.c (list4i): Rename from 'quad'. All uses changed.
1279 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1281 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1283 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1284 warning about mixing declarations and code in ISO C90.
1286 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1288 * window.c (Fsplit_window_internal): Set combination limit of
1289 new parent window to t iff Vwindow_combination_limit is t;
1290 fixing a regression introduced with the change from 2012-09-22.
1291 (Fset_window_combination_limit): Fix doc-string.
1293 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1295 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1296 amount when the scroll margins are too large. When scrolling
1297 backwards in the buffer, give up if cannot reach point or the
1298 scroll margin within a reasonable number of screen lines.
1299 Fixes point position in window under scroll-up/down-aggressively when
1300 point is positioned many lines beyond the window top/bottom.
1303 * ralloc.c (relinquish): If real_morecore fails to return memory
1304 to the system, don't crash; instead, leave the last heap
1305 unchanged and return. (Bug#12774)
1307 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1309 * lisp.h (AUTOLOADP): New macro.
1310 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
1311 * data.c (Ffset): Remove special ad-advice-info handling.
1312 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
1314 (Finteractive_form): Simplify.
1315 (Fquo): Don't insist on having at least 2 arguments.
1316 (Qdefalias_fset_function): New var.
1318 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1320 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

1324 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
1326 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1328 Fix recently introduced crash on MS-Windows (Bug#12839).
1329 * w32term.h (struct scroll_bar): Use convenient header.
1330 (SCROLL_BAR_VEC_SIZE): Remove.
1331 * w32term.c (x_scroll_bar_create): Use VECSIZE.
1333 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1335 Tweak last vectorlike_header change.
1336 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1337 vectorlike object on the free list. This is introduced to avoid
1338 some (but not all) pointer casting and aliasing problems, see
1339 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
1340 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
1342 (xvectype, xvecsize): Use them to examine Lisp_Object values.
1344 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1346 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
1347 been removed, so remove them here also.
1349 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1351 * doc.c (Fdocumentation): Handle new property
1352 dynamic-docstring-function to replace the old ad-advice-info.
1354 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
1356 * fns.c (Qeql, hashtest_eq): Now static.
1358 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>

1361 * fns.c (hashfn_eq, hashfn_eql, sxhash):
1362 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
1363 * buffer.c (compare_overlays): Use XLI rather than XHASH.
1365 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
1367 Use same hash function for hashfn_profiler as for hash_string etc.
1368 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
1369 * lisp.h (sxhash_combine): New inline function, with the contents
1370 of the old SXHASH_COMBINE.
1371 * profiler.c (hashfn_profiler): Use it, instead of having a
1372 special hash function containing a comparison that always yields 1.
1374 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1376 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1377 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1378 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1381 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1383 * image.c (xpm_make_color_table_h): Fix compiler error because
1384 make_hash_table changed.
1386 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
1388 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
1390 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1392 Use ad-hoc comparison function for the profiler's hash-tables.
1393 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1394 (make_log): Use them.
1395 (handle_profiler_signal): Don't inhibit quit any longer since we don't
1396 call Fequal any more.
1397 (Ffunction_equal): New function.
1398 (cmpfn_profiler, hashfn_profiler): New functions.

1405 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
1406 (hash_lookup, hash_remove_from_table): Move assertion checking of
1407 hashfn result here. Check hash-equality before calling cmpfn.
1408 (Fmake_hash_table): Adjust call to make_hash_table.
1409 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.

1415 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
1417 2012-11-08 Eli Zaretskii <eliz@gnu.org>
1419 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
1420 value of w32-scroll-lock-modifier is neither nil nor one of the
1421 known key modifiers. (Bug#12806)
1423 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1425 Shrink struct vectorlike_header to the only size field.
1426 * lisp.h (enum pvec_type): Avoid explicit enum member values.
1428 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
1429 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
1430 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
1431 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
1432 information from the vector header. Adjust comment.
1433 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
1434 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
1436 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.
1437 (struct vectorlike_header): Remove next member. Adjust comment.

1441 (sweep_string, lisp_malloc): Remove useless prototypes.
1442 (enum mem_type): Adjust comment.
1443 (NEXT_IN_FREE_LIST): New macro.
1444 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
1445 (Fmake_bool_vector): Likewise.
1446 (struct large_vector): New type to represent allocation unit for
1447 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
1448 (large_vectors): Change type to struct large_vector.
1449 (allocate_vector_from_block): Simplify.
1450 (PSEUDOVECTOR_NBYTES): Replace with...
1451 (vector_nbytes): ...new function. Adjust users.
1452 (sweep_vectors): Adjust processing of large vectors.
1453 (allocate_vectorlike): Likewise.
1454 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
1455 Add easserts. Adjust XSETPVECTYPESIZE usage.
1456 (allocate_buffer): Use BUFFER_PVEC_INIT.
1457 (live_vector_p): Adjust to match large vector.
1458 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
1459 * buffer.h (struct buffer): Add next member.
1460 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
1462 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
1463 * fns.c (internal_equal): Adjust to match enum pvec_type change.
1464 (copy_hash_table): Adjust to match vector header change.
1465 * lread.c (defsubr): Use XSETPVECTYPE.

1467 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
1468 (xvecsize): New command.
1470 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1472 * keyboard.c (event_to_kboard): Do not dereference
1473 frame_or_window field of SELECTION_REQUEST_EVENT
1474 and SELECTION_CLEAR_EVENT events (Bug#12814).
1475 * xterm.h (struct selection_input_event): Adjust comment.
1477 2012-11-07 Eli Zaretskii <eliz@gnu.org>
1479 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
1480 such as Scroll Lock, if the respective keys are treated as
1481 function keys, not as modifiers. This avoids destroying non-ASCII
1482 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
1484 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
1486 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
1488 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1490 Restore some duplicate definitions (Bug#12814).
1491 This undoes part of the 2012-11-03 changes. Some people build
1492 with plain -g rather than with -g3, and they need the duplicate
1493 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
1494 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
1495 Define as macros, as well as as enums or as constants.
1497 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
1499 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
1500 to keypad keys (Bug#12816).
1502 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1504 Minor adjustments of recently-changed frame functions.
1505 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
1506 known to be a frame (we're in the FRAMEP branch).
1507 * lisp.h (Qframep): Remove decl. frame.h declares this.
1508 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
1509 since they're meant for Lisp fixnum values.
1511 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1513 * window.c (Fwindow_combination_limit): Revert to the only
1514 required argument and adjust docstring as suggested in
1515 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
1516 by Martin Rudalics <rudalics@gmx.at>.
1518 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1520 Widely used frame validity and checking functions.
1521 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
1522 * frame.c (decode_live_frame, decode_any_frame): New functions.
1523 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
1524 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
1525 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
1526 (Fframe_pointer_visible_p): Use decode_any_frame.
1527 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
1528 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
1529 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
1530 (Fframe_focus): Likewise. Allow zero number of arguments.
1532 (frame_buffer_list, frame_buffer_predicate): Remove.
1533 * lisp.h (frame_buffer_predicate): Remove prototype.
1534 * buffer.c (Fother_buffer): Use decode_any_frame.
1535 * xdisp.c (Ftool_bar_lines_needed): Likewise.
1536 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
1537 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
1538 (Fclose_font, Ffont_info): Use decode_live_frame.
1539 * fontset.c (check_fontset_name): Likewise.
1540 * terminal.c (Fframe_terminal): Likewise.
1541 * w32fns.c (check_x_frame): Likewise.
1542 * window.c (Fminibuffer_window, Fwindow_at)
1543 (Fcurrent_window_configuration): Likewise.
1544 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
1545 Likewise. Allow zero number of arguments. Adjust docstring.
1546 * dispnew.c (Fredraw_frame): Likewise.
1547 * xfaces.c (frame_or_selected_frame): Remove.
1548 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
1549 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
1550 (Fframe_face_alist): Use decode_live_frame.
1551 * xfns.c (check_x_frame): Likewise.
1553 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1555 * window.c (quad): New function.
1556 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
1557 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
1558 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
1559 (Fwindow_line_height): Use it.
1560 (Fwindow_fringes): Use list3.
1561 (Fwindow_scroll_bars): Use list4.
1562 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
1563 (Fwindow_combination_limit): Allow zero number of arguments.
1565 2012-11-05 Eli Zaretskii <eliz@gnu.org>
1567 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
1569 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
1570 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
1571 file descriptor 2 for standard error. (Bug#12805)
1573 2012-11-05 Chong Yidong <cyd@gnu.org>
1575 * process.c (wait_reading_process_output): Revert previous change.
1577 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1579 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
1580 This removes code that has been obsolete since around 1990.
1581 * callproc.c (Fcall_process):
1583 * process.c (create_process):
1584 * term.c (dissociate_if_controlling_tty):
1585 Assume setsid exists.
1586 * callproc.c (child_setup): Assume setpgid exists and behaves as
1587 per POSIX.1-1988 or later.
1588 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1589 * emacs.c (shut_down_emacs):
1590 * sysdep.c (sys_suspend, init_foreground_group):
1591 Assume getpgrp behaves as per POSIX.1-1998 or later.
1592 * msdos.c (setpgrp): Remove.
1593 (tcgetpgrp, setpgid, setsid): New functions.
1594 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1595 * term.c (no_controlling_tty): Remove; unused.
1596 * w32proc.c (setpgrp): Remove.
1597 (setsid, tcgetpgrp): New functions.
1599 Simplify by assuming __fpending.
1600 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1601 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1602 Do not assume that __fpending's result fits in int.
1604 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1606 Remove EMACS_OUTQSIZE+sleep hack.
1607 * dispnew.c (update_frame_1): Remove hack for terminals slower
1608 than 2400 bps, which throttled Emacs by having it sleep.
1609 This code hasn't worked since at least 2007, when the multi-tty stuff
1610 was added, and anyway those old terminals are long dead.
1611 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1612 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1614 Fix data-loss with --version (Bug#9574).
1615 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1616 as we can't assume that emacs_strerror is initialized, and strerror
1617 is good enough here.
1618 (main): Invoke atexit earlier, to catch earlier instances of
1619 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1621 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1623 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1624 (keyDown): Remap keypad keys to X11 virtual key codes.
1626 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1628 Fix data-loss with --batch (Bug#9574).
1629 * emacs.c: Include <close-stream.h>.
1630 (close_output_streams): New function.
1631 (main): Pass it to atexit, so that Emacs closes stdout and stderr
1632 and handles errors appropriately.
1633 (Fkill_emacs): Don't worry about flushing, as close_output_stream
1636 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
1637 The symptom is a diagnostic "GLib-WARNING **: In call to
1638 g_spawn_sync(), exit status of a child process was requested but
1639 SIGCHLD action was set to SIG_IGN and ECHILD was received by
1640 waitpid(), so exit status can't be returned." The diagnostic
1641 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
1642 The real bug is a race condition between Emacs and glib: Emacs
1643 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
1644 so that glib can't find it. Work around the bug by invoking
1645 waitpid only on subprocesses that Emacs itself creates.
1646 * process.c (create_process, record_child_status_change):
1647 Don't use special value -1 in pid field, as the caller now must
1648 know the pid rather than having the callee infer it.
1649 The inference was sometimes incorrect anyway, due to another race.
1650 (create_process): Set new 'alive' member if child is created.
1651 (process_status_retrieved): New function.
1652 (record_child_status_change): Use it.
1653 Accept negative 1st argument, which means to wait for the
1654 processes that Emacs already knows about. Move special-case code
1655 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
1656 processes that have already been waited for, by testing and
1657 clearing new 'alive' member.
1658 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
1659 now does this internally.
1660 (handle_child_signal): Let record_child_status_change do all
1661 the work, since we do not want to reap all exited child processes,
1662 only the child processes that Emacs itself created.
1663 * process.h (Lisp_Process): New boolean member 'alive'.
1665 Omit duplicate definitions no longer needed with gcc -g3.
1666 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
1667 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
1668 Define only as macros. There's no longer any need to also define
1669 these symbols as enums or as constants, since we now assume
1670 gcc -g3 when debugging.
1672 2012-11-03 Eli Zaretskii <eliz@gnu.org>
1674 * lisp.mk: Adjust comments to the fact that term/internal is now
1675 loaded from loadup.el.
1677 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
1678 (msdos_fatal_signal): New function.
1679 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
1682 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
1683 for GCC versions before 4.
1684 (emacs_raise): Define to call msdos_fatal_signal.
1686 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
1687 iterator when starting in the middle of a display or overlay
1690 2012-11-03 Chong Yidong <cyd@gnu.org>
1692 * process.c (wait_reading_process_output): Clean up the last
1695 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1697 * process.c (wait_reading_process_output): Avoid a race condition
1698 with SIGIO delivery (Bug#11536).
1700 2012-11-03 Chong Yidong <cyd@gnu.org>
1702 * buffer.c (cursor_type): Untabify docstring.
1704 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1706 * frame.h (struct frame): Drop can_have_scroll_bars member
1707 which is meaningless for a long time. Adjust comments.
1708 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1709 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1711 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1713 * window.c (decode_next_window_args): Update window arg after
1714 calling decode_live_window and so fix crash reported at
1715 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1716 by Juanma Barranquero <lekktu@gmail.com>.
1717 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
1718 * font.c (Ffont_at): Likewise.
1720 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
1722 * widget.c (resize_cb): New function.
1723 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
1724 (EmacsFrameResize): Check if all is up to date before changing frame
1727 2012-11-02 Eli Zaretskii <eliz@gnu.org>
1729 Implement backtrace output for fatal errors on MS-Windows.
1730 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
1731 (BACKTRACE_LIMIT_MAX): New macro.
1732 (w32_backtrace): New function.
1733 (emacs_abort): Use w32_backtrace when the user chooses not to
1734 attach a debugger. Update the text of the abort dialog.
1736 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1738 Window-related stuff cleanup here and there.
1739 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
1740 Use decode_any_window.
1741 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
1742 * xdisp.c (Fformat_mode_line): Likewise.
1743 * font.c (Ffont_at): Use decode_live_window.
1744 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
1745 * window.c (decode_next_window_args): Likewise.
1746 (decode_any_window): Remove static.
1747 * window.h (decode_any_window): Add prototype.
1748 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
1749 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
1752 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1754 Remove pad from struct input_event.
1755 * termhooks.h (struct input_event): Remove padding field.
1757 * keyboard.c (event_to_kboard): Simplify because frame_or_window
1758 member is never cons for a long time. Adjust comment.
1759 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
1760 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
1761 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
1762 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
1764 2012-11-01 Eli Zaretskii <eliz@gnu.org>
1766 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
1768 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
1770 Fix crash when using Emacs as commit editor for git (Bug#12697).
1771 * callproc.c (setpgrp): Remove macro, as we now use setpgid
1772 and it is configured in conf_post.h.
1773 (Fcall_process): Don't invoke both setsid and setpgid; the former
1774 is enough, if it exists.
1775 * callproc.c (Fcall_process, child_setup):
1776 * process.c (create_process): Use setpgid.
1777 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
1779 * dispnew.c (init_display): Initialize the foreground group
1780 if we are running a tty display.
1781 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
1782 * lisp.h (init_foreground_group): New decl.
1783 * sysdep.c (inherited_pgroup): New static var.
1784 (init_foreground_group, tcsetpgrp_without_stopping)
1785 (narrow_foreground_group, widen_foreground_group): New functions.
1786 (init_sys_modes): Narrow foreground group.
1787 (reset_sys_modes): Widen foreground group.
1789 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
1791 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
1793 2012-10-31 Martin Rudalics <rudalics@gmx.at>
1795 * minibuf.c (read_minibuf): Restore current buffer since
1796 choose_minibuf_frame calling Fset_frame_selected_window may
1797 change it (Bug#12766).
1799 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
1801 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
1803 2012-10-30 Kenichi Handa <handa@gnu.org>
1805 * font.c (Ffont_at): If WINDOW is specified and it is not
1806 displaying the current buffer, signal an error.
1808 2012-10-29 Daniel Colascione <dancol@dancol.org>
1810 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
1811 In preparation for fixing bug#12739, move these functions from
1814 * coding.h, coding.c: ... to here, and compile them only when
1815 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
1816 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
1818 2012-10-28 Eli Zaretskii <eliz@gnu.org>
1820 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
1821 (timer_loop, getitimer, setitimer): Use it instead of
1822 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
1824 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
1827 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
1829 * nsterm.m (NO_APPDEFINED_DATA): New define.
1830 (last_appdefined_event_data): New variable
1831 (last_appdefined_event): Remove.
1832 (ns_select): Initialize t from last_appdefined_event_data instead
1833 of [last_appdefined_event data1].
1834 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
1835 remove last_appdefined_event (Bug#12698).
1837 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
1839 * frame.c (x_set_font): Catch internal error.
1841 2012-10-27 Eli Zaretskii <eliz@gnu.org>
1843 Avoid overflow in w32 implementation of interval timers.
1844 When possible, for ITIMER_PROF count only times the main thread
1846 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
1847 'volatile ULONGLONG' types. All the other data which was
1848 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
1849 (GetThreadTimes_Proc): New typedef.
1850 (w32_get_timer_time): New function, returns a suitable time value
1852 (timer_loop): Enter critical section when accessing ULONGLONG
1853 values of the itimer_data struct, as these accesses are no longer
1854 atomic. Call 'w32_get_timer_time' instead of 'clock'.
1855 Remove unused variable.
1856 (init_timers): Initialize s_pfn_Get_Thread_Times.
1857 (start_timer_thread): Don't assign itimer->caller_thread here.
1858 (getitimer): Assign itimer->caller_thread here.
1859 (setitimer): Always call getitimer to get the value of ticks_now.
1860 (sys_spawnve): Avoid compiler warning about format mismatch.
1862 2012-10-26 Eli Zaretskii <eliz@gnu.org>
1864 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
1865 mouse movement events if the menu bar is active. This avoids
1866 producing a busy "hour-glass" cursor by Windows if the mouse

2350 (ROUND_UP, ROUND_DOWN, get_page_size)
2351 (get_allocation_unit, get_processor_type, get_w32_major_version)
2352 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2353 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2354 (OS_NT, os_subtype, cache_system_info): Move here.
2356 * unexw32.c, unexcw.c: Include w32common.h.
2358 * emacs.c (main): Use (defined (WINDOWSNT) || defined
2359 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
2360 to call syms_of_w32select.
2362 * cygw32.h: Remove obsolete EXFUN declarations.
2364 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
2366 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
2367 of w32inevt.o from SOME_MACHINE_OBJECTS.
2369 2012-10-08 Daniel Colascione <dancol@dancol.org>
2371 * image.c: Permanent fix for JPEG compilation issue --- limit
2372 jpeglib `boolean' redefinition to Cygwin builds.
2374 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2376 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
2378 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
2381 2012-10-08 Daniel Colascione <dancol@dancol.org>
2383 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
2384 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
2385 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
2386 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
2387 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
2388 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
2389 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
2390 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
2391 now a supported configuration.
2393 * Makefile.in: consolidate image variables into LIBIMAGE; add
2394 W32_OBJ and W32_LIBS. Compile new files.
2397 (_DebPrint) declare tracing facility for W32 debugging. We need
2398 to unify tracing later.
2400 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
2401 unconditional use of W32 Unicode functions. Cygwin runs only on
2402 100% Unicode operating systems.
2404 * cygw32.c: New file. Define Cygwin-specific facilities.
2405 (Fcygwin_convert_path_to_windows)
2406 (Fcygwin_convert_path_from_windows): New user functions for
2407 accessing Cygwin path-munging routines.
2409 * cygw32.h: New file.
2410 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
2411 UTF-16LE strings temporarily inside non-Lisp-visible string
2414 (w32_strerror): Just what it says on the tin.
2416 * emacs.c: Make the NS fork-then-exec code for daemon-launching
2417 also run for Cygwin; both systems have the same problem with using
2418 GUI facilities in a forked child. Also call syms_of_cygw32,
2419 syms_of_w32select in correct places.
2421 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
2422 needs fork-then-exec for daemon launching.
2424 * font.h: Include frame.h.
2426 * image.c: Use the image library cache machinery only when we're
2427 compiling for native WINDOWSNT; Cygwin can use shared libraries
2428 like any other Unixlike system.
2430 * keyboard.c: Clarify a comment regarding the input loop.
2432 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
2433 functions directly instead of trying to detect at runtime that our
2434 host operating system supports them. We make this change for two
2435 reasons: Cygwin lacks support for the multibyte character
2436 conversion functions used by the legacy menu code, and Cygwin
2437 never needs to rely on non-Unicode APIs.
2439 * unexw32.c (hinst): Declare extern.
2441 * w32.c: Change header order;
2442 (w32_strerror): Move to w32fns.c because we need it for
2443 non-WINDOWSNT builds.
2445 * w32.h: Add #error macro to make sure we don't include w32.h for
2446 Cygwin builds. Remove w32select declarations.
2448 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
2449 w32fns.c. w32console.c is WINDOWSNT-only.
2451 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
2452 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
2454 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
2455 (w32_major_version, w32_minor_version, w32_build_number)
2456 (os_subtype, sound_type): Define here
2457 (w32_defined_color): Make color parameter const for consistency
2458 with other _defined_color functions.
2459 (w32_createwindow): Unconditionally call w32_init_class instead of
2460 doing so only when hprevinst is non-NULL. Plumbing hprevinst
2461 through the code is complex and unnecessary because class
2462 registration is practically free.
2463 (w32_name_of_message): New EMACSDEBUG-only function.
2464 (Fset_message_beep): Move here
2465 (Fx_open_connection): Require that the display name for Windows be
2466 "w32" for consistency, emacsclient disambiguation, and maybe, one
2467 day, multi-window-system support.
2468 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
2469 Cygwin files for W32 GUI facilities, since these clearly don't
2470 expect Cygwin names.
2471 (_DebPrint): Define.
2472 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
2473 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
2474 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
2475 (w32_last_error): Remove.
2477 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
2479 * w32heap.c (syspage_mask): Declare here.
2480 (cache_system_info): Remove.
2482 * w32inevt.c (faked_key): Define globally, not statically.
2483 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
2484 (w32_console_toggle_lock_key): Move to w32fns.c.
2486 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
2488 * w32proc.c (_DebPrint): Move to w32fns.c.
2489 * w32select.c: Include string.h, stdio.h for Cygwin.
2490 * w32select.h: New File.
2492 * w32term.c: Include io.h for non-CYGWIN builds; needed for
2494 (w32_message_fd): New variable. Under Cygwin, holds the file
2495 descriptor the system used to tell us about pending thread
2498 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
2499 that prevented compilation under non-WINDOWSNT systems.
2501 (w32_initialize): Open /dev/windows and assign it to
2502 w32_message_fd. Provide w32 feature.
2504 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
2505 (WM_EMACS_INPUT_READY): add.
2506 (prepend_msg, w32_message_fd): Declare globally.
2509 (keyboard_handle): Use only when WINDOWSNT.
2510 (notify_msg_ready): New function. Posts a message to the main
2511 thread's message queue under CYGWIN, which wakes up the main
2512 thread from select(2) by making the /dev/windows file descriptor
2513 ready. Under WINDOWSNT, it sets an event the same way the old
2516 (post, prepend_msg): Actually call notify_msg_ready instead of
2517 setting the input event directly.
2519 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2521 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2522 but it still has blocs in it, don't return it to the system,
2523 instead of aborting. (Bug#12402)
2525 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2527 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2529 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
2530 MAC_OS_X_VERSION_10_6.
2531 (syms_of_nsterm): Remove comment about Panther and above for
2533 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
2534 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
2535 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
2537 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
2538 MAC_OS_X_VERSION_10_4.
2540 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2541 MAC_OS_X_VERSION_10_2.
2543 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
2545 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
2546 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
2548 * nsterm.m (ns_in_resize): Remove (Bug#12479).
2549 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
2550 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
2551 Remove ns_in_resize check.
2552 (ns_clear_frame_area): Remove resize handle code.
2554 * nsfns.m (ns_in_resize): Remove.
2555 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
2556 Remove ns_in_resize check.
2558 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2560 Improve sys_siglist detection.
2561 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2562 defined as a macro, as is done in Solaris.
2563 (sys_siglist_entries): New macro.
2564 (save_strsignal): Use it.
2565 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2566 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2568 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2570 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2571 fullscreen/Fullscreen.
2573 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2574 tobar_height is new.
2576 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2577 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2578 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
2579 (windowDidResize:): Check for correct window if old style fullscreen.
2580 Capitalize word in comment. Remove incorrect comment.
2581 (initFrameFromEmacs:): tbar_height renamed tibar_height.
2582 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
2583 error in drawing background.
2584 (toggleFullScreen:): Remove comment. Rearrange calls.
2585 Set toolbar values to zero, save old height in tobar_height.
2586 Restore tool bar height when leaving fullscreen.
2587 (canBecomeMainWindow): New function.
2589 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
2591 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2593 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2595 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2597 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2598 that time stamps of directories could also be changed.
2599 Don't request the too broad GENERIC_WRITE, only the more restrictive
2600 FILE_WRITE_ATTRIBUTES access rights.
2602 * fileio.c (Fset_file_times): Special-case ignoring errors for
2603 directories only on MSDOS, not on MS-Windows.
2605 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2607 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2609 2012-10-04 Eli Zaretskii <eliz@gnu.org>
2611 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
2612 see whether CreateFile failed.
2614 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
2616 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2617 to avoid similar races.
2618 * keyboard.c (pending_signals): Now bool, not int.
2620 Port timers to OpenBSD, plus check for timer failures.
2621 OpenBSD problem reported by Han Boetes.
2622 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
2624 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2625 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2626 like OpenBSD, which has timer_settime but does not declare it.
2627 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2628 whether to use itimerspec-related primitives. All uses of
2629 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
2631 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2633 * profiler.c (handle_profiler_signal): Fix a malloc race
2634 that caused Emacs to hang on Fedora 17 when profiling Lisp.
2636 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
2638 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
2640 2012-10-02 Eli Zaretskii <eliz@gnu.org>
2642 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
2643 consistent with the change in return value of 'safe_strsignal'.
2645 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2647 Prefer plain 'static' to 'static inline' (Bug#12541).
2648 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
2649 (bidi_set_sor_type, bidi_push_embedding_level)
2650 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
2651 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
2652 (bidi_cache_search, bidi_cache_ensure_space)
2653 (bidi_cache_iterator_state, bidi_cache_find)
2654 (bidi_peek_at_next_level, bidi_set_paragraph_end)
2655 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2656 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
2657 Now 'static', not 'static inline'.
2659 Count overruns when profiling; change units to ns.
2660 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
2661 Give extra weight to samples after overruns, to attempt to count
2662 the time more accurately.
2663 (setup_cpu_timer): Change sampling interval units from ms to ns, since
2664 the underlying primitives nominally do ns.
2665 (Fprofiler_cpu_start): Document the change. Mention that
2666 the sampling intervals are only approximate.
2668 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2670 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
2672 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
2673 case for the special 0 coding-system.
2675 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
2676 (Fmake_overlay): Remove redundant tests.
2677 (fix_start_end_in_overlays): Remove redundant recentering.
2679 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
2681 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
2682 Update dependencies.
2684 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2686 Fix a malloc race condition involving strsignal.
2687 A signal can arrive in the middle of a malloc, and Emacs's signal
2688 handler can invoke strsignal, which can invoke malloc, which is
2689 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2690 Fix it by altering the signal handler so that it does not invoke
2692 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2693 * process.c (status_message): Use const pointer, in case strsignal
2694 is #defined to safe_strsignal.
2695 * sysdep.c (sys_siglist, init_signals): Always define and
2696 initialize a substitute sys_siglist if the system does not define
2697 one, even if HAVE_STRSIGNAL.
2698 (safe_strsignal): Rename from strsignal. Always define,
2699 using sys_siglist. Return a const pointer.
2700 * syssignal.h (safe_strsignal): New decl.
2701 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2703 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2705 * w32proc.c (timer_loop): Fix code that waits for timer
2706 expiration, to avoid high CPU usage.
2708 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2710 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2711 (sweep_weak_table): Remove redundant prototypes.
2713 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2715 * emacs.c: Move the inclusion of TERM_HEADER after including
2716 windows.h on WINDOWSNT. This avoids compilation problems with
2719 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2721 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
2722 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
2723 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
2724 as the previous version used 'void *'.
2726 * ralloc.c (ROUNDUP): Fix last change.
2727 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
2730 * w32proc.c <disable_itimers>: New static flag.
2731 (init_timers): Initialize it to zero, after creating the critical
2732 sections used by the timer threads.
2733 (term_timers): Set to 1 before deleting the critical sections.
2734 (getitimer, setitimer): If disable_itimers is non-zero, return an
2735 error indication without doing anything. Reported by Fabrice
2736 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
2737 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
2739 [!HAVE_SETITIMER]: Behave as the previous version that didn't
2742 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
2743 term_ntproc after all the other bookkeeping, to get timers working
2744 as long as possible.
2746 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2748 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
2749 Suggested by Juri Linkov in
2750 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
2752 Prefer plain 'static' to 'static inline' (Bug#12541).
2753 With static functions, modern compilers inline pretty well by
2754 themselves; advice from programmers often hurts as much as it helps.
2755 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
2756 this change shrinks the text size of the Emacs executable by 1.1%
2757 without affecting CPU significantly in my benchmark.
2758 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

3056 for consistency with other handlers.
3057 (setup_cpu_timer): New function, with much of what used to be in

3059 Prefer timer_settime if available, and prefer
3060 thread cputime clocks, then process cputime clocks, then
3061 monotonic clocks, to the old realtime clock. Use make_timeval
3062 to round more-correctly when falling back to setitimer.
3063 (Fprofiler_cpu_start): Use it.
3064 (Fprofiler_cpu_stop): Prefer timer_settime if available.

3280 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3282 Move pid_t related decls out of lisp.h.
3283 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
3284 (interruptible_wait_for_termination):
3285 Move these decls from lisp.h to syswait.h, since they use pid_t.
3286 Needed on FreeBSD; see Herbert J. Skuhra in
3287 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.

3334 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3336 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3337 fatal_error_backtrace.
3339 * w32proc.c (sys_kill): Undo last change: don't do anything when
3340 invoked to deliver SIGABRT to our own process. This is now
3341 handled by emacs_raise.
3343 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3345 * w32term.c (w32_read_socket): Remove leftover reference to
3346 interrupt_input_pending.
3348 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3350 Do not use SA_NODEFER.
3351 Problem reported by Dani Moncayo in
3352 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3354 * sysdep.c (emacs_abort): Do not reset signal handler.
3355 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3356 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3357 wanted even on POSIXish hosts, and it doesn't work on Windows.
3359 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3361 * xterm.c (x_term_init): Call fixup_locale before and after calling
3362 gtk_init (Bug#12392).
3364 2012-09-23 Chong Yidong <cyd@gnu.org>
3366 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3367 Vdynamic_library_alist.
3369 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3370 (Fgnutls_available_p): Caller changed.
3372 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3373 (Flibxml_parse_xml_region): Likewise.
3375 * dispextern.h (struct image_type): Remove arg from init function.
3377 * image.c (Finit_image_library, lookup_image_type)
3378 (define_image_type): Remove now-unneeded second arg.
3379 (init_xpm_functions, init_png_functions, init_jpeg_functions)
3380 (init_tiff_functions, init_gif_functions, init_svg_functions):
3381 Arglist and w32_delayed_load calling convention changed.
3382 (gs_type): Remove init_gs_functions; there is no such function.
3383 (valid_image_p, make_image): Fix caller to lookup_image_type.
3385 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3387 Simplify and avoid signal-handling races (Bug#12471).
3389 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3390 Avoid recursive loop if there's a fatal error in the function itself.
3391 * atimer.c (pending_atimers):
3392 * blockinput.h: Don't include "atimer.h"; no longer needed.
3393 (interrupt_input_pending): Remove. All uses removed.
3394 pending_signals now counts both atimers and ordinary interrupts.
3395 This is less racy than having three separate pending-signal flags.
3396 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3398 Rename from their upper-case counterparts BLOCK_INPUT,
3399 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3400 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3401 This makes it easier to access volatile variables more accurately.
3402 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3403 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3404 that's more reliable if the code is buggy and sets
3405 interrupt_input_blocked to a negative value. All uses changed.
3406 * atimer.c (deliver_alarm_signal):
3407 Remove. No need to deliver this to the parent; any thread can
3408 handle this signal now. All uses replaced by underlying handler.
3409 * atimer.c (turn_on_atimers):
3410 * dispnew.c (handle_window_change_signal):
3411 * emacs.c (handle_danger_signal):
3412 * keyboard.c (kbd_buffer_get_event):
3413 Don't reestablish signal handler; not needed with sigaction.
3414 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3416 Rework to avoid unnecessary accesses to volatile variables.
3417 (UNBLOCK_INPUT_TO): Now a function.
3418 (totally_unblock_input, unblock_input): New decls.
3419 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3420 (init_data): Remove. Necessary stuff now done in init_signal.
3421 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3422 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3423 (fatal_error_code): Remove; no longer needed.
3424 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3425 it doesn't always backtrace. All uses changed. No need to reset
3426 signal to default, since sigaction and/or die does that for us now.
3427 Use emacs_raise (FOO), not kill (getpid (), FOO).
3428 (main): Check more-accurately whether we're dumping.
3429 Move fatal-error setup to sysdep.c
3430 * floatfns.c: Do not include "syssignal.h"; no longer needed.
3431 * gtkutil.c (xg_get_file_name, xg_get_font):
3432 Remove no-longer-needed signal-mask manipulation.
3433 * keyboard.c, process.c (POLL_FOR_INPUT):
3434 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
3435 * keyboard.c (read_avail_input): Remove.
3436 All uses replaced by gobble_input.
3437 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
3438 (kbd_buffer_store_event_hold, gobble_input):
3439 (record_asynch_buffer_change) [USABLE_SIGIO]:
3440 (store_user_signal_events):
3441 No need to mess with signal mask.
3442 (gobble_input): If blocking input and there are terminals, simply
3443 set pending_signals to 1 and return. All hooks changed to not
3444 worry about whether input is blocked.
3445 (process_pending_signals): Clear pending_signals before processing
3446 them, in case a signal comes in while we're processing.
3447 By convention callers now test pending_signals before calling us.
3448 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
3449 New functions, to support changes to blockinput.h.
3450 (handle_input_available_signal): Now extern.
3451 (reinvoke_input_signal): Remove. All uses replaced by
3453 (quit_count): Now volatile, since a signal handler uses it.
3454 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
3455 All callers changed. Block SIGINT only if not already blocked.
3456 Clear sigmask reliably, even if Fsignal returns, which it can.
3457 Omit unnecessary accesses to volatile var.
3458 (quit_throw_to_read_char): No need to restore sigmask.
3459 * keyboard.c (gobble_input, handle_user_signal):
3460 * process.c (wait_reading_process_output):
3461 Call signal-handling code rather than killing ourselves.
3462 * lisp.h: Include <float.h>, for...
3463 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
3464 (pending_signals): Now volatile.
3465 (syms_of_data): Now const if IEEE floating point.
3466 (handle_input_available_signal) [USABLE_SIGIO]:
3467 (terminate_due_to_signal, record_child_status_change): New decls.
3468 * process.c (create_process): Avoid disaster if memory is exhausted
3469 while we're processing a vfork, by tightening the critical section
3471 (send_process_frame, process_sent_to, handle_pipe_signal)
3472 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
3474 (send_process): No need for setjmp/longjmp any more, since the
3475 SIGPIPE stuff is now gone. Instead, report an error if errno
3477 (record_child_status_change): Now extern. PID and W are now args.
3478 Return void, not bool. All callers changed.
3479 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
3480 Remove. All uses removed. This bug should be fixed now in a
3482 (wait_for_termination_1): Use waitpid rather than sigsuspend,
3483 and record the child status change directly. This avoids the
3484 need to futz with the signal mask.
3485 (process_fatal_action): Move here from emacs.c.
3486 (emacs_sigaction_flags): New function, containing
3487 much of what used to be in emacs_sigaction_init.
3488 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
3489 caught by emacs, to make races less likely.
3490 (deliver_process_signal): Rename from handle_on_main_thread.
3492 (BACKTRACE_LIMIT_MAX): Now at top level.
3493 (thread_backtrace_buffer, threadback_backtrace_pointers):
3495 (deliver_thread_signal, deliver_fatal_thread_signal):
3496 New functions, for more-accurate delivery of thread-specific signals.
3497 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
3498 (deliver_arith_signal): Handle in this thread, not
3499 in the main thread, since it's triggered by this thread.
3500 (maybe_fatal_sig): New function.
3501 (init_signals): New arg DUMPING so that we can be more accurate
3502 about whether we're dumping. Caller changed.
3503 Treat thread-specific signals differently from process-general signals.
3504 Block all signals while handling fatal error; that's safer.
3505 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
3507 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
3508 Ignore SIGPIPE unless batch.
3509 (emacs_backtrace): Output backtrace for the appropriate thread,
3510 which is not necessarily the main thread.
3511 * syssignal.h: Include <stdbool.h>.
3512 (emacs_raise): New macro.
3513 * xterm.c (x_connection_signal): Remove; no longer needed
3514 now that we use sigaction.
3515 (x_connection_closed): No need to mess with sigmask now.
3516 (x_initialize): No need to reset SIGPIPE handler here, since
3517 init_signals does this for us now.
3519 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3521 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3522 background rect may be larger (Bug#12245).
3524 2012-09-23 Chong Yidong <cyd@gnu.org>
3526 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3528 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3530 * .gdbinit: Just stop at fatal_error_backtrace.
3531 See Stefan Monnier's request in
3532 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3533 Remove no-longer-used query of system type.
3535 2012-09-22 Chong Yidong <cyd@gnu.org>
3537 * search.c (Freplace_match): Doc fix (Bug#12325).
3539 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3541 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3542 (Fline_end_position): Doc fix.
3544 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).

3548 * dispextern.h (struct image_type): Add new slot, storing a type
3549 initialization function.
3551 * image.c (define_image_type): Call the image initializer function
3552 if it is defined. Arguments and return value changed.
3553 (valid_image_p, make_image): Callers changed.
3554 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3555 (gif_type, imagemagick_type, svg_type, gs_type):
3556 Add initialization functions.
3557 (Finit_image_library): Call lookup_image_type.
3558 (CHECK_LIB_AVAILABLE): Macro deleted.
3559 (lookup_image_type): Call define_image_type here, rather than via
3560 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3561 (syms_of_image): Move define_image_type calls for xbm_type and
3562 pbm_type to lookup_image_type.
3564 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3566 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3567 'idle_timers' from here ...
3568 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3569 lists, to avoid infloops when the timer does something stupid,
3570 like reinvoke itself with the same or smaller time-out.
3573 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3575 * window.c (Fsplit_window_internal): Handle only Qt value of

3588 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3589 or that fprintf is async-signal-safe. POSIX doesn't require
3592 2012-09-22 Chong Yidong <cyd@gnu.org>
3594 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3597 2012-09-22 Kenichi Handa <handa@gnu.org>
3599 * composite.c (composition_reseat_it): Handle the case that a
3600 grapheme cluster is not covered by a single font (Bug#12352).
3602 2012-09-21 Chong Yidong <cyd@gnu.org>
3604 * image.c (define_image_type): Avoid adding duplicate types to
3605 image_types (Bug#12463). Suggested by Jörg Walter.

3615 * eval.c (Frun_hook_with_args_until_success)
3616 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3618 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3620 * fileio.c (Ffile_selinux_context): Only call freecon when
3621 lgetfilecon succeeded.
3622 (Fset_file_selinux_context): Likewise. (Bug#12444)
3624 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3626 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3627 reordering, locate the cursor by calling set_cursor_from_row; if
3628 that fails, clear the desired glyph matrix before returning a
3629 failure indication to the caller. Fixes leaving garbled display
3630 when fast scrolling with a down-key. (Bug#12403)
3631 (compute_stop_pos_backwards): Fix a typo that caused crashes while
3632 scrolling through multibyte text.
3634 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
3636 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
3637 calling mark_vectorlike since that's the one that marks the window.
3638 (mark_discard_killed_buffers): Mark the final cdr.
3639 * window.h (struct window): Move prev/next_buffers to the
3640 non-standard fields.
3641 * window.c (make_window): Initialize prev/next_buffers manually.
3643 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
3645 Omit unused arg EXPECTED from socket hooks.

3650 * w32term.c (w32_read_socket):
3651 * xterm.c (XTread_socket):
3652 Omit unused arg EXPECTED. All callers changed.
3653 (store_user_signal_events): Return void, not int, since callers no
3654 longer care about the return value. All uses changed.
3656 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
3658 * w32gui.h (XParseGeometry): Do not declare.
3660 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3662 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
3663 Ignore 'expected'. See Eli Zaretskii in

3666 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
3667 (XParseGeometry): Now static. Substitute extremal values for
3668 values that are out of range.
3670 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
3672 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
3674 * nsfns.m (XParseGeometry): Remove.
3675 (Fx_create_frame): Call x_set_offset to correctly interpret
3676 top_pos in geometry.
3678 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
3679 (Fx_parse_geometry): If there is a space in string, call
3680 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
3682 2012-09-17 Eli Zaretskii <eliz@gnu.org>
3684 * search.c (scan_buffer): Use character positions in calls to
3685 region_cache_forward and region_cache_backward, not byte
3686 positions. (Bug#12196)
3688 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3689 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3691 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3692 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3693 emacs_blocked_malloc, now deleted.
3695 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3697 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3698 The workaround was for improving performance on Solaris 2.4, but
3699 is getting in the way now. Emacs will still work if someone is
3700 still running Solaris 2.4 in a museum somewhere; Sun dropped
3701 support for Solaris 2.4 in 2003.
3702 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3703 * process.c (create_process) [HAVE_WORKING_VFORK]:
3704 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3705 since Emacs no longer uses vfork on that platform.
3707 2012-09-17 Glenn Morris <rgm@gnu.org>
3709 * emacs.c: Use COPYRIGHT.
3711 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3713 Remove configure's --without-sync-input option (Bug#12450).
3714 When auditing signal-handling in preparation for cleaning it up,
3715 I found that SYNC_INPUT has race conditions and would be a real
3716 pain to fix. Since it's an undocumented and deprecated
3717 configure-time option, now seems like a good time to remove it.
3718 Also see <http://bugs.gnu.org/11080#16>.
3719 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
3720 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
3721 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3722 (malloc_hysteresis):
3723 (check_depth) [XMALLOC_OVERRUN_CHECK]:
3724 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
3725 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
3726 (dont_register_blocks, bytes_used_when_reconsidered)
3727 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
3728 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
3729 [!SYSTEM_MALLOC && !SYNC_INPUT]:
3730 Remove. All uses removed.
3731 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
3732 implementation, one that depends on whether the new macro
3733 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
3735 * atimer.c (run_timers, handle_alarm_signal):
3736 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
3737 (handle_async_input, process_pending_signals)
3738 (handle_input_available_signal, init_keyboard):
3739 * nsterm.m (ns_read_socket):
3740 * process.c (wait_reading_process_output):
3741 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
3742 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
3744 * xterm.c (XTread_socket):
3746 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
3747 * eval.c (handling_signal): Remove. All uses removed.
3748 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
3749 All uses replaced with the SYNC_INPUT version.
3750 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
3752 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3755 * font.c (Ffont_shape_gstring): Remove unused local.
3757 2012-09-16 Glenn Morris <rgm@gnu.org>
3759 * Makefile.in (clean): No longer run nextstep's clean.
3761 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
3763 (ns-app): Move here from ns.mk, and simplify.
3764 (clean): Simplify nextstep entry.
3765 * ns.mk: Remove file.
3767 2012-09-17 Kenichi Handa <handa@gnu.org>
3769 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
3770 not covert the last few charactes.
3772 2012-09-16 Kenichi Handa <handa@gnu.org>
3774 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
3775 here, but just check the validity of glyphs in the glyph-string.
3777 2012-09-16 Martin Rudalics <rudalics@gmx.at>
3779 * window.c (Fwindow_parameter, Fset_window_parameter):
3780 Accept any window as argument (Bug#12452).
3782 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
3784 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
3785 to ns_term_init to avoid memory leak.
3787 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
3788 explicit retain/release.
3789 (ns_term_init): Only allow one display. Initialize outerpool and
3792 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3794 Port _setjmp fix to POSIXish hosts as well as Microsoft.
3795 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
3796 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
3797 the Microsoft problem in a different way, by altering ../nt/config.nt.
3799 2012-09-15 Eli Zaretskii <eliz@gnu.org>
3814 * w16select.c: Remove inclusion of setjmp.h, as it is now included
3815 by lisp.h. This completes removal of setjmp.h inclusion
3816 erroneously announced in the previous commit. (Bug#12446)
3818 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
3821 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
3822 not defined as a macro. The latter happens on MS-Windows.
3825 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3827 Port better to POSIX hosts lacking _setjmp (Bug#12446).
3828 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
3829 Some instances of '#include <setjmp.h>' removed, if the
3830 only reason for the instance was because "lisp.h" was included.
3831 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
3832 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
3833 and _longjmp with the new symbols. Emacs already uses _setjmp if
3834 available, so this change affects only POSIXish hosts that have
3835 sigsetjmp but not _setjmp, such as some versions of Solaris and
3836 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
3837 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
3838 (png_load_body) [HAVE_PNG]:
3839 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
3840 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
3841 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
3842 since PNG requires jmp_buf. This is the only exception to the
3843 general rule that we now use sys_setjmp and sys_longjmp.
3844 This exception is OK since this code does not change the signal
3845 mask or longjmp out of a signal handler.
3847 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
3849 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3850 Include "syssignal.h", for 'main_thread'.
3852 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
3854 Avoid out-of-range marker position (Bug#12426).
3855 * insdel.c (replace_range, replace_range_2):
3856 Adjust markers before overlays, as suggested by comments.
3857 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
3858 Remove redundant check before calling offset_intervals.
3860 2012-09-14 Martin Rudalics <rudalics@gmx.at>
3862 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
3863 current buffer (Bug#12387).
3865 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
3867 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
3869 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3871 Use a more backwards-compatible timer format (Bug#12430).
3872 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
3873 vector element, not from the 4th, since PSECS is now at the end.
3874 (Fcurrent_idle_time): Doc fix.
3876 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
3878 Function to mark objects and remove killed buffers at once.
3879 * alloc.c (discard_killed_buffers): Rename to ...
3880 (mark_discard_killed buffers) ... new name. Add marking
3881 of remaining objects. Fix comment. Adjust users.
3882 (mark_object): Do not touch frame buffer lists here.
3883 * frame.c (delete_frame): Reset frame buffer lists here.
3885 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3887 Better workaround for GNOME bug when --enable-gcc-warnings.
3888 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
3889 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
3890 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
3892 Simplify SIGIO usage (Bug#12408).
3893 The code that dealt with SIGIO was crufty and confusing, e.g., it
3894 played tricks like "#undef SIGIO" but these tricks were not used
3895 consistently. Simplify mostly by not #undeffing standard symbols,
3896 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
3897 or not as we please) rather than "defined SIGIO" (standard symbol
3898 that we probably shouldn't #undef).
3899 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
3900 Modules that need it can include it.
3901 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
3902 * dispextern.h (ignore_sigio): New decl.
3903 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
3904 unconditionally, since it's now a no-op if !USABLE_SIGIO.
3905 * emacs.c (shut_down_emacs):
3906 * keyboard.c (kbd_buffer_store_event_hold):
3907 Use ignore_sigio rather than invoking 'signal' directly.
3908 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
3910 (FIONREAD, SIGIO): Do not #undef.
3911 (tty_read_avail_input): Use #error rather than a syntax error.
3912 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
3913 for I_PIPE, used by SETUP_SLAVE_PTY.
3914 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
3915 * sysdep.c (croak): Remove; no longer needed. This bit of
3916 temporary code, with Fred N. Fish's comment that it's temporary,
3917 has been in Emacs since at least 1992!
3918 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
3919 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
3920 * syssignal.h (croak): Remove decl.
3921 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
3922 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
3923 now that we're termios-only.
3924 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
3925 * term.c (dissociate_if_controlling_tty): Use #error rather than
3928 Work around GCC and GNOME bugs when --enable-gcc-warnings.
3929 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
3930 to work around GNOME bug 683906.
3931 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
3932 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
3933 This works around GCC bug 54561.
3935 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3937 More fixes for 'volatile' and setjmp/longjmp.
3938 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
3939 * image.c (struct png_load_context) [HAVE_PNG]: New type.
3940 (png_load_body) [HAVE_PNG]:
3941 (jpeg_load_body) [HAVE_JPEG]:
3942 New function, with most of the old parent function's body.
3943 (png_load) [HAVE_PNG]:
3944 (jpeg_load) [HAVE_JPEG]:
3945 Invoke the new function, to avoid longjmp munging our locals.
3946 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
3947 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
3948 longjmp is passed 2, as the C standard doesn't guarantee this.
3949 Instead, store the failure code into mgr->failure_code.
3951 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3953 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
3954 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
3955 (syms_of_keyboard): Remove support for unread-command-char.
3957 2012-09-12 Eli Zaretskii <eliz@gnu.org>
3959 * w32proc.c (sys_kill): If PID is our process ID and the signal is
3960 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
3961 violation. (Bug#12426)
3963 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3965 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
3967 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3969 * eval.c: Add `inhibit-debugger'.
3970 (Qinhibit_debugger): New symbol.
3971 (call_debugger): Bind it instead of Qdebug_on_error.
3972 (maybe_call_debugger): Test Vinhibit_debugger.
3973 (syms_of_eval): Define inhibit-debugger.
3974 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
3975 (syms_of_xdisp): Remove inhibit-debug-on-message.
3977 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3979 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
3980 If a nonvolatile local variable is written before a _longjmp to
3981 the frame containing the variable, and is read after the _longjmp,
3982 the value read is indeterminate. Some local variables of type
3983 'struct handler' and 'struct catchtag' are used in this way, so
3984 mark each of their slots as volatile if the slot can be set before
3985 _longjmp and read afterwards.
3986 * lisp.h (struct handler): var and chosen_clause are now volatile.
3987 (struct catchtag): val, next, and pdlcount are now volatile.
3989 * bidi.c (bidi_push_it, bidi_pop_it):
3990 * fns.c (copy_hash_table):
3991 * image.c (define_image_type):
3992 * keyboard.c (kbd_buffer_store_event_hold):
3993 * process.c (Fprocess_send_eof):
3994 * xfaces.c (x_create_gc) [HAVE_NS]:
3995 * xgselect.c (xg_select):
3996 Prefer assignment to memcpy when either will do.
3998 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
3999 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4000 time an item is removed. No need to mark this function 'inline';
4001 the compiler knows better than we do.
4003 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4005 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4006 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4007 to change_frame_size (Bug#12388).
4008 (windowDidResize:): Pass YES to updateFrameSize.
4010 * nsterm.h: Add delay parameter to updateFrameSize.
4012 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4014 Discard killed buffers from deleted window and frame objects.
4015 This reduces an amount of references to killed buffers and
4016 helps GC to reclaim them faster.
4017 * alloc.c (discard_killed_buffers): New function.
4018 (mark_object): Use it for deleted windows and frames.
4019 (mark_object): If symbol's value is set up for a killed buffer
4020 or deleted frame, restore its global binding.
4021 * data.c (swap_in_global_binding): Add GC notice.
4022 (swap_in_symval_forwarding): Use convenient set_blv_where.
4023 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
4024 * window.h: ... to here.
4026 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4028 Convenient macro to check whether the buffer is live.
4029 * buffer.h (BUFFER_LIVE_P): New macro.
4030 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
4031 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
4033 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4035 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
4036 composition cases (Bug#12364).
4038 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
4039 overhang of succeeding glyphs overlapping box cursor.
4041 * w32term.c (x_draw_glyph_string): Likewise.
4043 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4045 Simplify, document, and port floating-point (Bug#12381).
4046 The porting part of this patch fixes bugs on non-IEEE platforms
4047 with frexp, ldexp, logb.
4048 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4050 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4051 support, by removing commented-out code and briefly listing the
4052 C89 functions excluded. The commented-out stuff was confusing
4053 maintenance, e.g., we thought we needed cbrt but it was commented out.
4054 (logb): Remove decl; no longer needed.
4055 (isfinite): New macro, if not already supplied.
4056 (isnan): Don't replace any existing macro.
4057 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4058 are present on all C89 platforms.
4059 (Ffrexp): Do not special-case zero, as frexp does the right thing
4061 (Flogb): Do not use logb, as it doesn't have the desired meaning
4062 on hosts that use non-base-2 floating point. Instead, stick with
4063 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4064 frexp, to avoid getting an unspecified result.
4066 * xdisp.c (Qinhibit_debug_on_message): Now static.
4068 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4070 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4071 NSBezierPath (Bug#12131).
4073 2012-09-10 Chong Yidong <cyd@gnu.org>
4075 * fns.c (Fdelq, Fdelete): Doc fix.
4077 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4079 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4080 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4082 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4084 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4085 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4088 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4090 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4091 left fringe if the window has a left margin. This avoids leaving
4092 traces of the cursor because its leftmost pixel is not drawn over.
4094 * dispnew.c (update_window_line): When the left margin area of a
4095 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4096 that screen line. (Bug#12277)
4098 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4100 Assume C89 or later for math functions (Bug#12381).
4101 This simplifies the code, and makes it a bit smaller and faster,
4102 and (most important) makes it easier to clean up signal handling
4103 since we can stop worring about floating-point exceptions in
4104 library code. That was a problem before C89, but the problem
4105 went away many years ago on all practical Emacs targets.
4106 * data.c, image.c, lread.c, print.c:
4107 Don't include <math.h>; no longer needed.
4108 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4109 might be autoconfigured, as that never happens.
4111 * doprnt.c (DBL_MAX_10_EXP):
4112 * print.c (DBL_DIG):
4113 Remove. C89 or later always defines these.
4114 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4115 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4116 (arith_error, domain_error, domain_error2):
4117 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4118 no longer needed -- we simply return what C returns. All uses removed.
4119 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4121 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4122 Remove. All uses expanded, as these macros are no longer used
4123 more than once and are now more trouble than they're worth.
4124 (Ftan): Use tan, not sin / cos.
4125 (Flogb): Assume C89 frexp.
4126 (fmod_float): Assume C89 fmod.
4127 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4128 (init_floatfns): Remove. All uses removed.
4130 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4132 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4133 compositeToPoint for OSX < 10.6 (Bug#12390).
4135 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4137 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4138 This produces more-accurate results.
4140 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4142 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4143 changes (Bug#12088).
4145 2012-09-08 Chong Yidong <cyd@gnu.org>
4147 * syntax.c (Fstring_to_syntax): Doc fix.
4149 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4151 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4152 in the internal border.
4153 (x_set_window_size): Remove static variables and their usage.
4154 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4155 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4156 Remove fringe/internal border adjustment (Bug#11052).
4157 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4158 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4159 (ns_fix_rect_ibw): Remove.
4160 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4161 (ns_dumpglyphs_box_or_relief): Ditto.
4162 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4164 (ns_dumpglyphs_image): Ditto.
4165 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4167 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4168 their usage. Add fringe_extended_p and its use as in other terms.
4169 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4170 scroll bar was removed.
4171 (updateFrameSize): New function.
4172 (windowDidResize): Move code to updateFrameSize and call it.
4174 * nsterm.h (EmacsView): Add updateFrameSize.
4176 2012-09-07 Chong Yidong <cyd@gnu.org>
4178 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4180 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4182 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4184 More signal-handler cleanup (Bug#12327).
4185 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4186 Problem introduced when merging patches. Noted by Eli Zaretskii in
4187 <http://bugs.gnu.org/12327#67>.
4188 * floatfns.c: Comment fix.
4189 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4190 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4191 and anyway the declaration is harmless even if SIGDANGER is not defined.
4192 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4193 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4194 source files not surprisingly expected syssignal.h to define, or
4195 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4196 Include <sys/ioctl.h>, for FIONREAD.
4197 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4198 This eliminates a problem whereby other files mysteriously had
4199 to include "syssignal.h" before including "systty.h" if they
4200 wanted to use "#ifdef SIGIO".
4202 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4204 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4206 * w32.c (sigemptyset): Empty the set.
4207 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4209 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4211 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4213 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4214 (mark_object): Likewise for frame objects.
4216 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4218 * syssignal.h (handle_on_main_thread): Always declare,
4219 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4220 This ports to platforms without HAVE_PTHREAD.
4222 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4224 Signal-handler cleanup (Bug#12327).
4225 Emacs's signal handlers were written in the old 4.2BSD style with
4226 sigblock and sigmask and so forth, and this led to some
4227 inefficiencies and confusion. Rewrite these to use
4228 pthread_sigmask etc. without copying signal sets around. Also,
4229 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4230 'signal', and instead use functions that do not attempt to take
4231 over the system name space. This patch causes Emacs's text
4232 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4233 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4234 Do not include <signal.h> or "syssignal.h", as these
4235 modules do not use signals.
4236 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4237 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4238 Do not include <signal.h>, as "syssignal.h" does that for us now.
4239 * atimer.c (sigmask_atimers): New function.
4240 (block_atimers, unblock_atimers): New functions,
4241 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4243 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4244 no longer needed here.
4245 * emacs.c (main): Inspect existing signal handler with sigaction,
4246 so that there's no need to block and unblock SIGHUP.
4247 * sysdep.c (struct save_signal): New member 'action', replacing
4248 old member 'handler'.
4249 (save_signal_handlers, restore_signal_handlers):
4250 Use sigaction instead of 'signal' to save and restore.
4251 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4252 New function. All users of 'signal' modified to use set_sighandler
4253 if they're writeonly, and to use sys_signal if they're read+write.
4254 (emacs_sigaction_init, forwarded_signal): New functions.
4255 (sys_signal): Remove. All uses replaced by calls to sigaction
4256 and emacs_sigaction_init, or by direct calls to 'signal'.
4257 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4258 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4259 all uses replaced by pthread_sigmask etc. calls.
4260 * syssignal.h: Include <signal.h>.
4261 (emacs_sigaction_init, forwarded_signal): New decls.
4262 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
4263 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
4264 (sigmask, sys_sigmask): Remove; no longer needed.
4265 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4266 (sigblock, sigunblock, sigfree):
4267 (sigsetmask) [!defined sigsetmask]:
4268 Remove. All uses replaced by pthread_sigmask.
4269 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4270 no longer need to be replaced, and its typical old uses
4271 are now done via emacs_sigaction_init and sigaction.
4272 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4273 (sys_sigdel): Remove; unused.
4274 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4276 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4278 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4279 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4281 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4283 Explicitly mark buffer_defaults and buffer_local_symbols.
4284 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4285 mark_local_symbols here.
4286 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4287 since special buffers aren't marked here any more.
4288 (allocate_buffer): Chain new buffer with all_buffers here...
4289 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4291 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4292 (syms_of_buffer): Remove staticpro of the above.
4293 (init_buffer_once): Set names for buffer_defaults and
4294 buffer_local_symbols.
4296 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4298 Use bool for booleans in font-related modules.
4299 * font.c (font_intern_prop, font_style_to_value)
4300 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
4301 (generate_otf_features, font_check_otf_features, font_check_otf)
4302 (font_match_p, font_list_entities, font_at):
4303 * fontset.c (fontset_id_valid_p, reorder_font_vector
4304 (fontset_find_font, Fset_fontset_font)
4305 (face_suitable_for_char_p) [0]:
4306 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4307 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
4308 (m17n_flt_initialized, ftfont_shape_by_flt):
4309 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
4310 * nsfont.m (nsfont_draw):
4311 * w32font.c (w32font_draw):
4312 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4313 Use bool for booleans.
4314 * font.h: Adjust to above API changes.
4315 (struct font, struct font_driver, struct font_driver_list):
4316 Use bool for booleans.
4317 (struct font): Remove useless member encoding_type.
4319 * fontset.c, xftfont.c: Omit unnecessary static decls.
4321 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4323 * alloc.c (mark_object): Revert window marking code
4324 since it's unsafe for the Fset_window_configuration.
4326 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4328 Fix race conditions with signal handlers and errno (Bug#12327).
4329 Be more systematic about preserving errno whenever a signal
4330 handler returns, even if it's not in the main thread. Do this by
4331 renaming signal handlers to distinguish between signal delivery
4332 and signal handling. All uses changed.
4333 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4334 * data.c (deliver_arith_signal): Rename from arith_error.
4335 * dispnew.c (deliver_window_change_signal): Rename from
4336 window_change_signal.
4337 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4338 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4339 * keyboard.c (deliver_input_available_signal): Rename from
4340 input_available_signal.
4341 (deliver_user_signal): Rename from handle_user_signal.
4342 (deliver_interrupt_signal): Rename from interrupt_signal.
4343 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4344 (deliver_child_signal): Rename from sigchld_handler.
4345 * atimer.c (handle_alarm_signal):
4346 * data.c (handle_arith_signal):
4347 * dispnew.c (handle_window_change_signal):
4348 * emacs.c (handle_fatal_signal, handle_danger_signal):
4349 * keyboard.c (handle_input_available_signal):
4350 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4351 * process.c (handle_pipe_signal, handle_child_signal):
4352 New functions, with the actual signal-handling code taken from the
4353 original respective signal handlers, sans the sporadic attempts to
4354 preserve errno, since that's now done by handle_on_main_thread.
4355 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4356 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4357 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4359 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4360 Move initialization of main_thread to sysdep.c's init_signals.
4361 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4362 our usage, and simplifies the mainline code.
4363 (record_child_status_change): New static function, as a helper
4364 for handle_child_signal, and with most of the old child handler's
4366 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4367 (handle_child_signal): Use the above.
4368 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4369 Moved here from emacs.c.
4370 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4371 code moved here from emacs.c's main function.
4372 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4373 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4374 This lets callers save and restore errno properly.
4376 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4378 Remove redundant or unused things here and there.
4379 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4380 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4381 * editfns.c (Fcompare_buffer_substrings): Likewise.
4382 * frame.h (struct terminal, struct font_driver_list):
4383 Remove redundant declarations.
4384 * window.h (Qleft, Qright): Likewise.
4386 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4388 Do not mark objects from deleted buffers, windows and frames.
4389 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4390 (mark_object): Likewise for windows and frames.
4392 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4394 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4395 buffer_defaults and buffer_local_symbols as valid objects.
4396 Return special value to denote them.
4398 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4400 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4401 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4402 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4403 (file_name_absolute_p, Fsubstitute_in_file_name):
4404 (check_executable, check_writable, Ffile_accessible_directory_p)
4405 (Fset_file_selinux_context, Fdefault_file_modes)
4406 (Finsert_file_contents, choose_write_coding_system)
4407 (Fwrite_region, build_annotations, a_write, e_write)
4409 * filelock.c (boot_time_initialized, get_boot_time)
4410 (get_boot_time_1, lock_file_1, within_one_second):
4411 * floatfns.c (in_float):
4412 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4413 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4414 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4415 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4416 * window.c (compare_window_configurations):
4417 Use bool for booleans.
4418 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4419 (Fdefault_file_modes): Now mode_t, not int, for modes.
4420 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4421 (internal_delete_file): Now returns void, not a (boolean) int,
4422 since nobody was looking at the return value.
4423 * lisp.h, window.h: Adjust to above API changes.
4425 * xdisp.c (set_message): Simplify and reindent last change.
4427 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
4429 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
4431 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
4433 * eval.c (call_debugger): Make the function non-static so that we
4434 can call it from set_message.
4436 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
4437 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
4439 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4441 Give more-useful info on a fatal error (Bug#12328).
4442 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
4443 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
4444 of doing the work ourselves.
4445 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
4446 do most of the work.
4447 (fatal_error_backtrace): New function, taken from the guts
4448 of the old fatal_error_signal, but with a new option to output
4450 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
4451 info about the signal than just its number.
4452 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
4453 * sysdep.c: Include <execinfo.h>
4454 (emacs_backtrace): New function, taken partly from the previous
4455 code of the 'die' function.
4456 (emacs_abort): Call fatal_error_backtrace rather than abort.
4458 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
4460 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
4461 eager (load-time) macro-expansion.
4462 * lisp.mk (lisp): Add macroexp.
4464 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4466 Simplify redefinition of 'abort' (Bug#12316).
4467 Do not try to redefine the 'abort' function. Instead, redo
4468 the code so that it calls 'emacs_abort' rather than 'abort'.
4469 This removes the need for the NO_ABORT configure-time macro
4470 and makes it easier to change the abort code to do a backtrace.
4471 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
4472 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
4473 Remove; sysdep.c's emacs_abort now takes its place.
4474 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
4475 'abort' changed to use 'emacs_abort'.
4476 * msdos.c (dos_abort) [defined abort]: Remove; not used.
4477 (abort) [!defined abort]: Rename to ...
4478 (emacs_abort): ... new name.
4479 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
4480 the place of the old 'abort' in emacs.c.
4481 * w32.c, w32fns.c (abort): Do not #undef.
4482 * w32.c (emacs_abort): Rename from w32_abort.
4484 2012-09-04 Eli Zaretskii <eliz@gnu.org>
4486 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
4487 offsets[j].dv, since the y axis of the screen coordinates points
4488 down, while the y axis of the font definition coordinates points
4489 up. This fixes display of Arabic diacritics such as KASRA and
4490 KASRATAN. (Bug#11860)
4492 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4494 Be more systematic about _setjmp vs setjmp.
4495 * alloc.c (test_setjmp, mark_stack):
4496 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
4497 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
4498 (png_load, my_error_exit, jpeg_load):
4499 * process.c (send_process_trap, send_process):
4500 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
4501 The underscored versions are up to 30x faster on some hosts.
4502 Formerly, the code used setjmp+longjmp sometimes and
4503 _setjmp+_longjmp at other times, with no particular reason to
4504 prefer setjmp+longjmp.
4506 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
4508 Fix minor problem found by static checking.
4509 * buffer.c (Fdelete_all_overlays): Return nil.
4511 2012-09-03 Martin Rudalics <rudalics@gmx.at>
4513 * buffer.c (Fdelete_all_overlays): New function.
4515 2012-09-03 Chong Yidong <cyd@gnu.org>
4517 * gtkutil.c: Add extern decl for Qxft.
4519 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4521 * emacs.c, eval.c: Use bool for boolean.
4522 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
4523 (malloc_using_checking) [DOUG_LEA_MALLOC]:
4524 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
4525 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
4526 (main, decode_env_path, Fdaemon_initialized):
4527 * eval.c (call_debugger, Finteractive_p, interactive_p):
4528 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
4529 (maybe_call_debugger, Fbacktrace):
4530 * process.c (read_process_output, exec_sentinel):
4531 Use bool for booleans.
4532 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
4533 All callers changed.
4534 * eval.c (interactive_p): Omit always-true boolean argument
4535 EXCLUDE_SUBRS_P. All callers changed.
4536 * dispextern.h, lisp.h: Reflect above API changes.
4537 * firstfile.c (dummy): Use the address of 'main', whose signature
4538 won't change, instead of the address of 'initialize', whose
4539 signature just changed from int to bool.
4540 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
4541 * msdos.c (fatal_error_in_progress): ... from here.
4542 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4544 (redisplay_internal, unwind_redisplay): Simply clear
4545 REDISPLAYING_P when unwinding, instead of saving its previous,
4546 always-false value and then restoring it.
4548 Clean up some extern decls.
4549 Mostly, this hoists extern decls out of .c files and into .h files.
4550 That way, we're more likely to catch errors if the interfaces change.
4551 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4552 declare xg_mark_data.
4553 * dispextern.h (x_frame_parm_handlers):
4555 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
4556 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
4557 (Qultra_bold, Qoblique, Qitalic):
4558 Move extern decl here from .c file.
4559 * alloc.c (xg_mark_data) [USE_GTK]:
4561 * eval.c (Qlexical_binding):
4562 * fns.c (time) [!HAVE_UNISTD_H]:

4766 * lread.c (init_lread): For out-of-tree builds, only add the
4767 source directory's site-lisp dir to the load-path if it exists,
4768 consistent with in-tree builds. (Bug#12302)
4770 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

5009 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
5011 * lisp.h (functionp): New function (extracted from Ffunctionp).
5012 (FUNCTIONP): Use it.
5013 * eval.c (Ffunctionp): Use it.
5015 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5017 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
5018 as that's faster and simpler than static storage. Don't bother
5019 with the g_main_context_query overhead if g_main_context_pending
5020 says no events are pending.
5021 (gfds, gfds_size): Remove these static vars.
5022 (xgselect_initialize): Remove; no longer needed.
5023 All uses and decls removed.
5025 * emacs.c (fatal_error_signal_hook): Remove.
5026 All uses removed. This leftover from old code was always 0.
5028 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
5029 * casefiddle.c (casify_object, casify_region):
5030 * casetab.c (set_case_table):
5031 * category.c, category.h (word_boundary_p):
5032 * category.h (CHAR_HAS_CATEGORY):
5033 Use bool for booleans, instead of int.
5035 2012-08-25 Eli Zaretskii <eliz@gnu.org>
5037 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
5039 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5041 On assertion failure, print backtrace if available.
5042 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
5043 (die) [ENABLE_CHECKING]: Print a backtrace if available.
5044 * Makefile.in (LIB_EXECINFO): New macro.
5047 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
5048 * bytecode.c (exec_byte_code):
5049 * callint.c (check_mark, Fcall_interactively):
5050 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
5051 (getenv_internal, sync_process_alive, call_process_exited):
5052 * lisp.h (USE_SAFE_ALLOCA):
5053 Use bool for booleans, instead of int.
5054 * lisp.h, process.h: Adjust prototypes to match above changes.
5055 * callint.c (Fcall_interactively): Don't assume the mark's
5056 offset fits in 'int'.
5058 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
5060 * buffer.c, buffer.h: Use bool for boolean.
5061 * buffer.c (reset_buffer_local_variables)
5062 (buffer_lisp_local_variables, Fset_buffer_modified_p)
5063 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
5064 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
5065 (overlay_touches_p, overlay_strings, Foverlay_put)
5066 (report_overlay_modification, call_overlay_mod_hooks):
5067 (mmap_enlarge, mmap_set_vars):
5068 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
5069 Use bool for booleans, instead of int.
5070 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5071 since the 1-or-0 return value is always ignored anyway.
5072 (mmap_initialized_p):
5073 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5074 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5076 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5078 * bidi.c: Use bool for boolean.
5079 This is a bit more readable, and makes the text segment of bidi.o
5080 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
5081 Presumably it's faster too.
5082 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
5084 (bidi_cache_find_level_change, bidi_cache_iterator_state)
5085 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
5086 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
5087 (bidi_explicit_dir_char, bidi_level_of_next_char)
5088 (bidi_find_other_level_edge, bidi_move_to_visually_next):
5089 Use bool for booleans, instead of int.
5090 * dispextern.h (bidi_init_it, bidi_paragraph_init)
5091 (bidi_unshelve_cache): Adjust decls to match code.
5093 2012-08-23 Martin Rudalics <rudalics@gmx.at>
5095 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
5098 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5100 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
5101 * atimer.h: Include <stdbool.h>.
5103 2012-08-22 Dan Nicolaescu <dann@gnu.org>
5105 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
5106 compile time tests instead of run time tests on systems that do
5108 (FRAME_MAC_P): Remove leftover from deleted code.
5109 * frame.c (syms_of_frame): Remove leftover from deleted code.
5111 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
5113 * nsterm.m (insertText:): Don't clear modifiers if code is space.
5115 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5117 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5118 Otherwise, the compiler complains about (A?B:C) where B is void
5119 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5120 (fontset_add): Return void, for FONTSET_ADD.
5122 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5124 * alloc.c: Use bool for booleans.
5125 (gc_in_progress, abort_on_gc)
5126 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5127 (dont_register_blocks) [GC_MALLOC_CHECK]:
5128 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
5129 (check_string_bytes, make_specified_string, memory_full)
5130 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
5131 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
5132 (mark_stack, valid_pointer_p, make_pure_string)
5133 (Fgarbage_collect, survives_gc_p, gc_sweep):
5134 Use bool for booleans, instead of int.
5135 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5136 Remove unused local.
5137 * alloc.c (PURE_POINTER_P):
5138 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
5139 * editfns.c (Fformat):
5140 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
5142 * fns.c (sweep_weak_table):
5143 * lisp.h (suppress_checking, push_message, survives_gc_p)
5144 (make_pure_string, gc_in_progress, abort_on_gc):
5145 * lread.c (readchar, read1):
5146 * print.c (Fprin1_to_string):
5147 * xdisp.c (push_message):
5148 Use bool for booleans affected directly or indirectly by
5151 Make recently-introduced setters macros.
5152 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
5153 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5154 (set_fontset_default, set_fontset_fallback): Rename from their
5155 upper-case counterparts, and make them functions rather than macros.
5156 This is more consistent with the other recently-introduced setters.
5157 These don't need to be inline, since they're local.
5159 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
5161 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
5162 the loop (Bug#12247).
5164 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5166 * lisp.h (vcopy): Use memcpy rather than our own loop.
5167 This fixes a performance regression introduced by the recent
5168 addition of vcopy. This means 'vcopy' will need to be modified
5169 for a copying collector, but that's OK. Also, tighten the
5170 checking in the assertion.
5172 2012-08-21 Eli Zaretskii <eliz@gnu.org>
5174 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5175 components for RTL text (Bug#11860). Adjust X-OFFSET of each
5176 non-base glyph for the width of the base character, according to
5177 what x_draw_composite_glyph_string_foreground expects.
5178 Generate WADJUST value according to composition_gstring_width's
5179 expectations, to produce correct width of the composed character.
5180 Reverse the sign of the DU offset produced by ScriptPlace.
5182 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5184 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
5186 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5188 Avoid direct writes to contents member of struct Lisp_Vector.
5189 * lisp.h (vcopy): New function to copy data into vector.
5190 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
5191 * fns.c (Ffillarray): Use ASET.
5192 * keyboard.c (timer_check_2): Use AREF and ASET.
5193 (append_tool_bar_item, Frecent_keys): Use vcopy.
5194 * lread.c (read_vector): Use ASET.
5195 * msdos.c (Frecent_doskeys): Use vcopy.
5196 * xface.c (Finternal_copy_lisp_face): Use vcopy.
5197 (Finternal_merge_in_global_face): Use ASET and vcopy.
5198 * xfont.c (xfont_list_pattern): Likewise.
5200 2012-08-21 Martin Rudalics <rudalics@gmx.at>

5203 the position of its buffer's point.
5204 (Fset_window_point): For the selected window always go in its
5205 buffer to the specified position.
5207 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5209 Setter macros for fontsets.
5210 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
5211 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
5212 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
5215 2012-08-20 Glenn Morris <rgm@gnu.org>
5217 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
5218 Don't assume that `ln -f' works.
5220 2012-08-20 Eli Zaretskii <eliz@gnu.org>
5222 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
5223 and later about non-assignments with no effect. See discussion at
5224 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
5227 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5229 Inline setter functions for Lisp_Objects slots of struct specbinding.
5230 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
5233 2012-08-20 Martin Rudalics <rudalics@gmx.at>
5235 * window.c (select_window): Always make selected window's buffer
5238 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>

5241 * category.h (CATEGORY_DOCSTRING): Use AREF.
5242 (SET_CATEGORY_DOCSTRING): Use ASET.
5243 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
5245 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5247 Inline setter functions for hash table members.
5248 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
5249 (set_hash_hash, set_hash_index): Rename with _slot suffix.
5250 (set_hash_key_and_value, set_hash_index, set_hash_next)
5251 (set_hash_hash): New functions.
5252 * charset.c, fns.c: Adjust users.
5254 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5256 Inline getter and setter functions for per-buffer values.
5257 * buffer.h (per_buffer_default, set_per_buffer_default)
5258 (per_buffer_value, set_per_buffer_value): New functions.

5260 * buffer.c, data.c: Adjust users.
5262 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
5264 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
5266 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
5268 Rely on <config.h> + <unistd.h> to declare 'environ',
5269 as gnulib does this if the system doesn't.
5270 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
5271 Remove declaration. MS-Windows declares it on stdlib.h which is
5272 included by conf_post.h.
5273 * emacs.c (environ) [DOUG_LEA_MALLOC]:
5274 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
5275 * vm-limit.c: Include <unistd.h>, for 'environ'.
5277 * unexaix.c, unexcoff.c: Include "mem-limits.h".
5278 (start_of_data): Remove decl; mem-limits.h provides it.
5280 * xdisp.c (handle_invisible_prop): Make it a bit faster
5281 and avoid a gcc -Wmaybe-uninitialized diagnostic.
5283 2012-08-19 Chong Yidong <cyd@gnu.org>
5285 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
5288 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
5290 * .gdbinit: Use call instead of set when calling a function in the
5293 * data.c (set_internal): Don't use set_blv_found.
5294 (Fkill_local_variable): Likewise.
5296 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
5298 * nsfont.m (ns_ascii_average_width): Ensure the string
5299 ascii_printable is initialized with a null-terminated character
5300 array. Otherwise, it can contain undesired extra characters.
5302 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5304 port new setting code to Sun C 5.8 2005/10/13
5305 * chartab.c, lisp.h (char_table_set, char_table_set_range):
5306 Return void, not Lisp_Object. Otherwise, the compiler
5307 complains about (A?B:C) where B is void and C is Lisp_Object
5308 when compiling CHAR_TABLE_SET, due to the recent change to
5309 the API of sub_char_table_set_contents.
5311 2012-08-18 Chong Yidong <cyd@gnu.org>
5313 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
5314 for the string case (Bug#3874).
5316 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5318 * buffer.h (BSET): Remove (Bug#12215).

5397 are compiled into code.
5398 (tset_param_alist): New setter function.
5400 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>

6141 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
6142 * w32.c (init_environment): Change the default values of many
6143 environment variables in dflt_envvars[] to NULL, to avoid pushing
6144 them into environment when they were not already defined.
6145 Remove the code that deletes site-lisp subdirectories from the default
6146 value of EMACSLOADPATH, as it is no longer needed.
6147 (check_windows_init_file): Now external, not static.
6148 Use Vload_path as is, without adding anything, as this function is now
6149 called when Vload_path is already set up.
6151 * w32.h (check_windows_init_file): Add prototype.
6153 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

6197 Remove unnecessary pointer casts.
6198 * alloc.c (record_xmalloc): New function.
6199 * lisp.h (record_xmalloc): New decl.
6200 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
6201 more like a function. This is because the pointer cast is not
6202 needed. All uses changed.
6203 * print.c (print_string, print_error_message): Avoid length recalc.
6205 Improve fix for macroexp crash with debugging (Bug#12118).
6206 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
6207 ARRAY_MARK_FLAG when checking subscripts, because ASET is
6208 not supposed to be invoked from the garbage collector.

6210 (gc_aset): New function, which is like ASET but can be
6211 used in the garbage collector.

6240 with addition of handling of symlinks and support for 'lstat'.
6241 If possible, get file's attributes and security information by
6242 handle, not by name. Produce S_IFLNK bit for symlinks, when
6243 called from 'lstat'.
6244 (stat, lstat): New functions, call 'stat_worker'.
6245 (symlink, readlink, careadlinkat): Rewritten to create and resolve
6246 symlinks when the underlying filesystem supports them.
6248 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
6250 Fix macroexp crash on Windows with debugging (Bug#12118).
6251 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
6252 checking subscripts; problem introduced with the recent
6253 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
6254 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
6255 since it's used in non-static inline functions now.
6257 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
6258 Don't assume buffer size fits in 'int'. Remove unused local.

6278 * composite.c (COMPOSITE_INLINE):
6279 * dispnew.c (DISPEXTERN_INLINE):
6280 * sysdep.c (SYSTIME_INLINE):
6281 Define to EXTERN_INLINE, so that the corresponding functions
6282 are compiled into code.
6283 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
6284 (INLINE_HEADER_END): New macros.
6285 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

6305 hard-coding the path separator.
6307 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
6309 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
6310 This how ASET and AREF are supposed to work, and makes
6311 it easier to think about future improvements. See
6312 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
6313 * charset.h (set_charset_attr): New function.

6782 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6784 Fast save_excursion_save and save_excursion_restore.
6785 * lisp.h (struct Lisp_Excursion): New data type.
6786 (PVEC_EXCURSION): New pseudovector type.
6787 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
6788 to deal with it. Adjust comments.

6802 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
6803 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
6804 emacs.c, as this is a more-suitable home. Had this been done earlier
6805 the fix for 12036 would have avoided some of the problems noted in
6806 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
6807 would have been more obvious.
6808 * emacs.c: Do not include <verify.h>; no longer needed.
6809 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
6810 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
6811 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6812 Remove; now done in lisp.h.
6813 * lisp.h (PUBLISH_TO_GDB): New macro.

6817 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
6818 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
6819 not be usable in #if. This simplifies things.
6821 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
6823 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
6825 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

6828 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
6829 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
6830 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
6831 Adjust to changes in lisp.h and emacs.c, by using
6832 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
6833 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
6834 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
6835 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
6836 instead of gdb_valbits.
6837 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
6838 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
6839 instead of gdb_array_mark_flag.
6840 (xboolvector): Get size from $->size, not $->header.size.
6841 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
6842 (xreload, hook-run, hookpost-run): Remove.
6843 * emacs.c: Include <verify.h>.
6844 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
6845 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
6847 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
6848 (gdb_USE_LSB_TAG): New enum constants.
6849 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6850 Also define these as enum constants, so they're visible to GDB.
6851 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
6852 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
6853 as constants, so they're visible to GDB.

6855 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
6856 Now enum constants, not macros, so they're visible to GDB.
6857 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
6858 more convenient now. All uses changed.
6859 (VALMASK) [USE_LSB_TAG]: Also define in this case.
6860 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
6862 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

6869 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
6870 add argument, tune behavior, and adjust all callers.
6872 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
6874 Use typedef for EMACS_INT, EMACS_UINT.
6875 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
6876 than macros. This simplifies debugging in the usual case, since
6877 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
6878 and it allows expressions involving EMACS_INT casts.
6879 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
6881 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

6893 Adjust buffer text indirection counters at the end of Fkill_buffer.
6894 * buffer.c (Fkill_buffer): Adjust indirection counters when the
6895 buffer is definitely dead. This should really fix an issue reported
6896 by Christoph Scholtes again. (Bug#12007).
6897 (init_buffer_once): Initialize indirection counters of
6898 buffer_defaults and buffer_local_symbols (for sanity and safety).
6900 2012-07-24 Eli Zaretskii <eliz@gnu.org>
6902 * xdisp.c (init_iterator): Don't compute dimensions of truncation
6903 and continuation glyphs on tooltip frames, leave them at zero.

6931 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
6933 Swap buffer text indirection counters in Fbuffer_swap_text.
6934 * buffer.c (Fbuffer_swap_text): Swap indirections too.
6935 This avoids crash reported by Christoph Scholtes at
6936 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
6938 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
6940 * nsmenu.m (Popdown_data): New struct.

6963 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
6965 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
6966 as it's limited by the amount of memory, not by INT_MAX.
6968 2012-07-21 Eli Zaretskii <eliz@gnu.org>
6970 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
6971 in special-event-map. See the discussion at

7052 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
7053 'for_each_per_buffer_object_at'.

7121 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
7123 * eval.c (Fdefvar): Don't check constants since we only set the var if
7124 it's not yet defined anyway (bug#11904).
7126 * lisp.h (last_undo_boundary): Declare new var.
7127 * keyboard.c (command_loop_1): Set it.
7128 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
7129 were auto-added by the command loop (bug#11774).

7673 (font_open_by_name): Change to use length argument.
7674 Adjust users accordingly.
7675 * font.h (font_open_by_name, font_parse_xlfd, font_unparse_xlfd):
7677 * xfont.c (xfont_decode_coding_xlfd, font_unparse_xlfd):
7678 Change to return ptrdiff_t.
7679 (xfont_list_pattern, xfont_match): Use length returned by

7691 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
7693 Remove "#define unix" that is no longer needed (Bug#11905).
7694 * s/aix4-2.h (unix): Remove; no longer needed.
7696 EMACS_TIME simplification (Bug#11875).
7697 This replaces macros (which typically do not work in GDB)
7698 with functions, typedefs and enums, making the code easier to debug.
7699 The functional style also makes code easier to read and maintain.
7700 * systime.h: Include <sys/time.h> on all hosts, not just if
7701 WINDOWSNT, since 'struct timeval' is needed in general.
7702 (EMACS_TIME): Now a typedef, not a macro.
7703 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
7705 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
7706 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
7707 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
7708 (EMACS_TIME_LE): Now functions, not macros.
7709 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
7710 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
7711 which are not functions. All uses rewritten to use:
7712 (make_emacs_time): New function.
7713 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
7714 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
7715 not functions. All uses rewritten to use the following, respectively:
7716 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
7717 (add_emacs_time, sub_emacs_time): New functions.
7718 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
7719 * fileio.c (Fcopy_file):
7720 * xterm.c (XTflash): Get the current time closer to when it's used.
7721 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

7728 * frame.c (Fmake_terminal_frame):
7729 * gtkutil.c (get_utf8_string):
7731 * nsmenu.m (ns_update_menubar):
7732 * regex.c (regerror):
7733 Prefer memcpy to strncpy and strncat when either will do.
7734 * fileio.c (Fsubstitute_in_file_name):
7735 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
7736 (menu_separator_name_p):
7737 * nsmenu.m (ns_update_menubar):
7738 Prefer memcmp to strncmp when either will do.
7739 * nsterm.m: Include <ftoastr.h>.
7741 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
7742 Prefer snprintf to strncpy.
7743 * nsterm.m (ns_term_init):
7744 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
7745 * nsterm.m (ns_term_init):
7746 Avoid the need for strncpy, by using build_string or
7747 make_unibyte_string directly. Use dtoastr, not snprintf.
7748 * process.c (Fmake_network_process): Diagnose service names that
7749 are too long, rather than silently truncating them or creating
7750 non-null-terminated names.
7751 (Fnetwork_interface_info): Likewise, for interface names.
7752 * sysdep.c (system_process_attributes) [GNU_LINUX]:
7753 Prefer sprintf to strncat.
7754 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
7755 Prefer vsnprintf to vsprintf + strncpy.
7757 2012-07-10 Glenn Morris <rgm@gnu.org>
7759 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
7760 Clarify fallback case.
7762 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7764 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
7765 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
7766 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
7767 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
7768 where argument type is known to be a Lisp_Cons.
7770 2012-07-10 Tom Tromey <tromey@redhat.com>
7772 * bytecode.c (BYTE_CODE_THREADED): New macro.

7780 Optimize pure C strings initialization.
7781 * lisp.h (make_pure_string): Fix prototype.
7782 (build_pure_c_string): New function, defined as static inline. This
7783 provides a better opportunity to optimize away calls to strlen when
7784 the function is called with compile-time constant argument.
7785 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
7786 argument, adjust users accordingly. Use build_pure_c_string where
7788 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
7789 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
7790 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
7792 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7794 Avoid calls to strlen in miscellaneous functions.
7795 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
7796 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
7797 * lread.c (openp): Likewise.
7799 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7801 Avoid calls to strlen in path processing functions.
7802 * fileio.c (file_name_as_directory): Add comment. Change to add
7803 srclen argument and return the length of result. Adjust users
7805 (directory_file_name): Fix comment. Change to add srclen argument,
7806 swap 1st and 2nd arguments to obey the common convention.
7807 Adjust users accordingly.
7808 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
7810 2012-07-10 Glenn Morris <rgm@gnu.org>
7812 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
7813 Move PENDING_OUTPUT_COUNT definition to configure.
7815 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
7816 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
7817 * s/gnu.h (DATA_START): Move definitions to configure.
7819 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
7820 We include usg5-4-common.h, which defines them both.
7822 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
7823 O_RDONLY already includes it).
7825 Stop ns builds setting the EMACSLOADPATH environment variable.
7826 * nsterm.m (ns_load_path): Rename from ns_init_paths.
7827 Now it does not set EMACSLOADPATH, just returns the load-path string.
7828 * nsterm.h: Update accordingly.
7829 * lread.c [HAVE_NS]: Include nsterm.h.
7830 (init_lread) [HAVE_NS]: Use ns_load_path.
7831 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
7833 2012-07-09 Glenn Morris <rgm@gnu.org>
7835 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
7836 since the included bsd-common.h does so.
7838 Stop ns builds setting the EMACSPATH environment variable.
7839 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
7840 (ns_init_paths): Do not set EMACSPATH.
7841 * nsterm.h (ns_exec_path): Add it.
7842 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
7845 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
7847 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
7849 * process.c (wait_reading_process_output): 'waitchannels' was unset
7850 when read_kbd || !NILP (wait_for_cell); fix this.
7852 Add GCC-style 'const' attribute to functions that can use it.
7853 * character.h (char_resolve_modifier_mask):
7854 * keyboard.h (make_ctrl_char):
7855 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
7856 (init_character_once, next_almost_prime, init_fns, init_image)
7857 (flush_pending_output, init_sound):
7858 * mem-limits.h (start_of_data):

7862 Declare the dummy function with ATTRIBUTE_CONST.
7863 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
7864 Add decls with ATTRIBUTE_CONST.
7866 Minor improvements to make_formatted_string.
7867 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
7868 where int is good enough, as vsprintf returns an int.
7869 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
7871 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7873 Use make_formatted_string to avoid double length calculation.
7874 * lisp.h (make_formatted_string): New prototype.

7880 * frame.c (make_terminal_frame, set_term_frame_name)
7881 (x_report_frame_params): Likewise.
7882 * image.c (gs_load): Likewise.
7883 * minibuf.c (get_minibuffer): Likewise.

7898 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7900 Move marker debugging code under MARKER_DEBUG.
7901 * marker.c (MARKER_DEBUG): Move marker debugging code under
7902 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
7903 for bootstrap with --enable-checking (~3x slowdown reported
7904 by Juanma Barranquero <lekktu@gmail.com>).
7905 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
7907 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
7909 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
7910 See <http://bugs.gnu.org/11825#29>.
7912 2012-07-08 Eli Zaretskii <eliz@gnu.org>
7914 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
7915 has no font, use the frame's font. (Bug#11813)
7916 (display_line): Add commentary about displaying truncation glyphs
7918 (produce_special_glyphs): Move here from term.c.
7920 * term.c (produce_special_glyphs): Move to xdisp.c.
7922 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
7925 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
7927 * xdisp.c (display_line): Avoid warning about implicit declaration
7930 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
7932 * lisp.h: Remove empty conditional.
7934 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7936 * lread.c (load_path_check): Now static.
7938 Fix some minor --with-ns problems found by static checking.
7939 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
7940 (x_set_font) [!HAVE_X_WINDOWS]:
7941 * image.c (xpm_load_image) [HAVE_NS]:
7942 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
7943 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
7944 Remove unused local.
7945 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
7946 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
7947 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
7948 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
7949 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
7950 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
7951 Fix pointer signedness problem.
7952 * xfaces.c (FRAME_X_FONT_TABLE):
7953 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
7955 2012-07-07 Glenn Morris <rgm@gnu.org>
7957 * lread.c (load_path_check): New function, split from init_lread.
7958 (init_lread): Reorganize. Motivation:
7959 If EMACSLOADPATH is set, check/warn about that rather than the
7960 defaults, which we are not going to use. Hence we can remove
7961 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
7962 Don't warn if site-lisp directories are missing.
7963 If not installed, start from a blank load-path, since
7964 PATH_LOADSEARCH refers to the eventual installation directories.
7966 2012-07-07 Eli Zaretskii <eliz@gnu.org>
7968 Support truncation and continuation glyphs on GUI frames, when
7969 fringes are disabled. (Bug#11832)
7970 * xdisp.c (init_iterator): Get dimensions of truncation and
7971 continuation glyphs even if on GUI frames.
7972 Adjust it->last_visible_x on GUI frames when the left or right fringes,
7973 or both, are absent.
7974 (start_display, move_it_in_display_line_to): Handle the case of a
7975 GUI frame without a fringe to display continuation or truncation
7977 (insert_left_trunc_glyphs): Support GUI frames: make sure
7978 truncation glyphs overwrite enough glyphs from the current line to
7979 have sufficient space in pixels.
7980 (display_line): Support truncation and continuation glyphs on GUI
7981 frames. If some spare pixels are left on the line after inserting
7982 the truncation glyphs, fill that space with a stretch glyph of a
7983 suitably computed width.
7985 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
7986 produce_glyphs, to support GUI sessions.
7988 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7990 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
7992 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
7994 Do not require float-time's arg to fit in time_t (Bug#11825).
7995 This works better on hosts where time_t is unsigned, and where
7996 float-time is applied to the (negative) difference between two times.
7997 * editfns.c (decode_time_components): Last arg is now double *,
7998 not int *, and means to store all the result as a double, without
7999 worrying about whether the seconds part fits in time_t.
8000 All callers changed.
8001 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8002 All callers changed.
8003 (Ffloat_time): Do not fail merely because the specified time falls
8004 outside of time_t range.
8006 2012-07-07 Glenn Morris <rgm@gnu.org>
8008 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

8012 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
8014 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
8015 Update dependencies.
8017 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
8019 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8021 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
8022 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
8023 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
8024 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
8025 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
8026 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
8028 * xfont.c (compare_font_names): Redo to omit the need for casts.
8030 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
8032 * xfns.c (Fx_change_window_property): Doc fix.
8033 * w32fns.c (Fx_change_window_property): Doc fix.
8035 * w32fns.c (Fx_window_property): Accept the same arguments as the
8036 X Windows version. Doc fix.
8037 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
8039 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
8040 Eli Zaretskii <eliz@gnu.org>
8042 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
8043 Windows-specific code from nt/config.nt moved here.
8044 Obsolete settings removed.
8046 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8048 * process.c: Avoid unnecessary calls to gettime.
8049 (wait_reading_process_output): Don't get the time of day
8050 when gobbling data immediately and not waiting, as there's no need
8051 for it in that case. This removes a FIXME.
8053 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8055 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
8056 is defined (Bug#11768).
8058 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

8062 if buffer is not multibyte.
8063 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8064 Call byte_char_debug_check with correct arguments.
8066 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8068 Compile marker debugging code only if ENABLE_CHECKING is defined.
8069 * marker.c (byte_char_debug_check, count_markers):
8070 Use only if ENABLE_CHECKING is defined.
8071 (byte_debug_flag): Remove.
8072 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8073 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
8075 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8077 Avoid code repetition in marker-related functions.
8078 * marker.c (attach_marker): New function.
8079 (Fset_marker, set_marker_restricted, set_marker_both)
8080 (set_marker_restricted_both): Use it.

8103 * window.c (save_window_save): Likewise.
8105 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8107 Do not use Fdelete_overlay in delete_all_overlays
8108 to avoid redundant calls to unchain_overlay.
8109 * buffer.c (drop_overlay): New function.
8110 (delete_all_overlays, Fdelete_overlay): Use it.
8111 * minibuf.c (get_minibuffer): Fix comment.
8113 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8115 Port to OpenBSD 5.1 amd64.
8116 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8117 This is needed for OpenBSD, and should be harmless on all BSD systems.
8118 Also, include <sys/sysctl.h>, as it should be available on all
8119 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8120 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8121 use p_pid member, not kp_proc.pid.
8123 2012-07-06 Glenn Morris <rgm@gnu.org>
8125 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8127 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8129 More xmalloc and related cleanup.
8130 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
8131 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
8132 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

8136 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
8137 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
8138 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8140 Omit needless casts involving void * pointers and allocation.
8141 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8142 as the former is more robust if P's type is changed.
8143 Prefer xzalloc to xmalloc + memset 0.
8144 Simplify malloc-or-realloc to realloc.
8145 Don't worry about xmalloc returning a null pointer.
8146 Prefer xstrdup to xmalloc + strcpy.
8147 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8149 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8150 alloca of a constant.
8152 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8154 * xdisp.c (display_line): Fix horizontal pixel coordinates when
8155 hscroll is larger than the line width. Fixes long and futile
8156 looping inside extend_face_to_end_of_line (on a TTY) producing
8157 glyphs that are not needed and thrown away.
8159 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8161 * marker.c (set_marker_restricted_both): Simplify by using
8164 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8166 * editfns.c (region_limit): Simplify by using clip_to_bounds.
8168 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
8170 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
8171 not defined (Bug#11768).
8172 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
8173 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
8174 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
8175 followed by gtk_box_set_homogeneous (Bug#11768).
8176 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
8177 (update_theme_scrollbar_width, xg_create_scroll_bar):
8178 Use gtk_scrollbar_new (Bug#11768).
8179 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
8180 (is_box_type): New function (Bug#11768).
8181 (xg_tool_item_stale_p): Call is_box_type.
8182 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
8183 with default display (Bug#11768).
8185 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8187 * xdisp.c (window_hscroll_limited): New function.
8188 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8189 coordinates when window's hscroll is set to insanely large
8192 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
8194 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
8195 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
8197 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8200 * lisp.h (xzalloc): New prototype. Omit needless casts.
8201 * alloc.c (xzalloc): New function. Omit needless casts.

8253 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8255 * fileio.c (time_error_value): Check the right error number.
8256 Problem reported by Troels Nielsen in
8257 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
8259 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8261 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8262 This should be fixed in a better way; see Eli Zaretskii in
8263 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8264 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8266 * fileio.c (time_error_value): Rename from special_mtime.
8267 The old name's problems were noted by Eli Zaretskii in
8268 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8270 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8271 This variable's comment says Emacs needs at least one GDB-visible
8272 symbol of type enum pvec_type, to work around GDB problems.
8273 The symbol's value doesn't matter.
8275 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8276 that causes compilation to fail on pre-C99 compilers.
8278 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
8280 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
8281 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
8283 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8285 * buffer.c (init_buffer_once): Fix initialization of
8286 headers for buffer_defaults and buffer_local_symbols.
8287 Reported by Juanma Barranquero <lekktu@gmail.com>.
8289 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
8291 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
8292 * lisp.h (enum pvec_type): Use fewer bits.
8293 (PSEUDOVECTOR_SIZE_BITS): New constant.
8294 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
8295 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
8296 change in pvec_type.
8297 (PSEUDOVECTOR_TYPEP): New macro.
8298 (TYPED_PSEUDOVECTORP): Use it.
8299 * fns.c (internal_equal): Adapt code to extract pvectype.
8300 * emacs.c (gdb_pvec_type): Update type.
8301 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
8302 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
8303 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
8304 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
8305 (sweep_vectors): Use it. Use local var `total_bytes' instead of
8306 abusing vector->header.next.nbytes.
8307 (live_vector_p): Use PVEC_TYPE.
8308 (mark_object): Adapt code to extract pvectype. Use switch.
8310 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8312 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
8313 Tighten new eassert a bit.
8315 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8317 Fix compilation with --enable-gcc-warnings and -O1
8319 * doprnt.c (doprnt): Change type of tem to int, initialize
8320 to avoid compiler warning. Add eassert.
8321 * search.c (simple_search): Initialize match_byte to avoid
8322 compiler warning. Add eassert.
8324 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8326 Avoid weird behavior with large horizontal scrolls.
8327 Without this change, for example, large hscroll values would
8328 mess up Emacs's display on Fedora 15 x86, presumably due to
8329 overflows in int calculations in the display code.
8330 Also, if buffers had long lines, Emacs would freeze.
8331 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8332 (set_window_hscroll): New function, containing the old guts of
8333 Fset_window_hscroll. Return the clipped value.
8334 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
8335 This avoids the need to check against PTRDIFF_MAX.
8337 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
8339 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8341 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
8343 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8345 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
8346 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8347 since GCC 4.4.6 issues a bogus warning for them.
8349 Fix bugs in file timestamp newness comparisons.
8350 * fileio.c (Ffile_newer_than_file_p):
8351 * lread.c (Fload): Use full timestamp resolution of files,
8352 not just the 1-second resolution, so that files that are only
8353 slightly newer still count as newer.
8354 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8355 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8357 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8359 * fileio.c: Improve handling of file time marker. (Bug#11852)
8360 (special_mtime): New function.
8361 (Finsert_file_contents, Fverify_visited_file_modtime):
8362 Use it to set special mtime values consistently.
8364 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
8366 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8367 marker for non-existing file. (Bug#11852)
8369 2012-07-03 Glenn Morris <rgm@gnu.org>
8371 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8372 and did not make it into globals.h).
8374 2012-07-03 Tom Tromey <tromey@redhat.com>
8376 * window.c (Fset_window_margins, Fset_window_fringes)
8377 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
8378 * textprop.c (Fprevious_property_change): No longer static.
8379 * syntax.c (Fsyntax_table_p): No longer static.
8380 * process.c (Fget_process, Fprocess_datagram_address): No longer

8395 * composite.c (Fcomposition_get_gstring): No longer static.
8396 * callproc.c (Fgetenv_internal): No longer static.
8398 * ccl.h: Remove EXFUNs.

8400 * dispextern.h: Remove EXFUNs.
8401 * intervals.h: Remove EXFUNs.
8402 * fontset.h: Remove EXFUN.
8403 * font.h: Remove EXFUNs.
8404 * dosfns.c (system_process_attributes): Remove EXFUN.
8405 * keymap.h: Remove EXFUNs.
8406 * lisp.h: Remove EXFUNs.
8407 * w32term.h: Remove EXFUNs.
8408 * window.h: Remove EXFUNs.
8409 * xsettings.h: Remove EXFUN.
8410 * xterm.h: Remove EXFUN.
8412 2012-07-03 Glenn Morris <rgm@gnu.org>
8414 * lisp.h (Frandom): Make it visible to C.
8415 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
8416 buffer for invisible buffers. (Bug#1229)
8418 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8420 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
8421 values which aren't power of 2.
8422 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
8423 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
8426 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
8428 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
8430 * alloc.c (mark_object): Revert part of last patch to use `switch'.
8432 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8434 * alloc.c (allocate_vector_block): Remove redundant
8435 calls to mallopt if DOUG_LEA_MALLOC is defined.
8436 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
8437 avoid calls to mallopt if zero_vector is returned.
8439 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8441 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
8442 is enabled, avoid dereferencing NULL current_sblock if
8445 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8447 Cleanup basic buffer management.
8448 * buffer.h (struct buffer): Change layout to use generic vector
8449 marking code. Fix some comments. Change type of 'clip_changed'
8450 to bitfield. Remove unused #ifndef old.
8451 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
8452 (GET_OVERLAYS_AT): Fix indentation.
8453 (for_each_per_buffer_object_at): New macro.
8454 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
8455 (Fbuffer_local_variables): Use it.
8456 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
8457 * alloc.c (allocate_buffer): Adjust to match new layout of
8458 struct buffer. Fix comment.
8459 (mark_overlay): New function.
8460 (mark_buffer): Use it. Use mark_vectorlike to mark normal
8461 Lisp area of struct buffer.
8462 (mark_object): Use it. Adjust marking of misc objects
8463 and related comments.
8465 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
8467 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
8468 wrapper that is not needed because the wrapped code is a no-op (zero
8469 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
8470 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
8472 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
8474 * alloc.c (mark_buffer): Simplify. Remove prototype.
8475 (mark_object): Add comment. Reorganize marking of vector-like
8476 objects. Use CHECK_LIVE for all vector-like objects except buffers
8477 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
8478 Avoid redundant calls to mark_vectorlike for bool vectors.
8480 2012-06-30 Glenn Morris <rgm@gnu.org>
8482 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
8484 * epaths.in (PATH_SITELOADSEARCH): New.
8485 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
8486 This is rather than relying on --enable-locallisppath elements
8487 having "site-lisp" in their names. (Bug#10208#25, 11658)
8489 2012-06-30 Eli Zaretskii <eliz@gnu.org>
8491 * w32proc.c (sys_select): Accept and ignore one more argument.
8493 * w32.c (emacs_gnutls_pull): Call select with one more argument.
8495 * sysselect.h [DOS_NT]: Don't include sys/select.h.
8496 (pselect) [!MS_DOS]: Redirect to sys_select.
8498 * sysdep.c: Don't include dos.h and dosfns.h.
8500 * process.c (sys_select):
8501 * msdos.c (sys_select): Accept one more argument and ignore it.
8503 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
8504 adapt data types and code to that.
8507 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
8508 which clashes with the gnulib function of the same name.
8510 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8512 * font.c (font_style_to_value, font_style_symbolic)
8513 (font_prop_validate_style): Add type checks for values in
8516 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8518 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8521 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8523 * xdisp.c (try_window_id): Undo last change.
8525 * w32.c (getwd): Adjust commentary about startup_dir.
8526 (init_environment): Always call sys_access, even in non-MSVC
8527 builds. Don't chdir to the directory of the Emacs executable.
8528 This undoes code from 1997 which was justified by the need to
8529 "avoid conflicts when removing and renaming directories". But its
8530 downside was that every relative file name was being interpreted
8531 relative to the directory of the Emacs executable, which can never
8532 be TRT. In particular, it broke sys_access when called with
8533 relative file names.
8534 (sys_access): Map GetLastError to errno.
8536 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8538 * window.h (struct window): Change type of 'fringes_outside_margins'
8539 to bitfield. Fix comment. Adjust users accordingly.
8540 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
8542 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8545 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
8547 * gnutls.c (emacs_gnutls_handshake):
8548 Add QUIT to make the loop interruptible.
8550 2012-06-29 Glenn Morris <rgm@gnu.org>
8552 * charset.c (init_charset): Make lack of etc/charsets fatal.
8554 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8556 * editfns.c (region_limit): Fix type mismatch.
8558 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8560 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
8561 undefined. Convert from xassert to eassert.
8562 * nsmenu.m: Convert from xassert to eassert.
8563 * nsterm.m: Likewise.
8565 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
8567 * editfns.c (region_limit): Clip to narrowing (bug#11770).
8569 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
8571 Avoid integer overflow on scroll-left and scroll-right.
8572 * window.c (HSCROLL_MAX): New macro.
8573 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
8574 overflow when requested scroll falls outside ptrdiff_t range.
8576 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8578 * window.h (struct window): Change type of 'hscroll',
8579 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
8580 'last_modified' and 'last_overlay_modified' to EMACS_INT.
8581 Adjust users accordingly.
8582 * xdisp.c (try_cursor_movement): Replace type check with eassert.
8583 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8584 from EMACS_INT to ptrdiff_t.
8585 (make_window): Omit redundant initialization.

8726 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
8728 Use sprintf return value instead of invoking strlen on result.
8729 In the old days this wasn't portable, since some sprintf
8730 implementations returned char *. But they died out years ago and
8731 Emacs already assumes sprintf returns int.
8732 Similarly for float_to_string.
8733 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

8741 Use sprintf or float_to_string result to avoid need to call strlen.
8742 * data.c (Fnumber_to_string):
8743 Use make_unibyte_string, since the string must be ASCII.
8744 * lisp.h, print.c (float_to_string): Now returns int length.
8745 * term.c (produce_glyphless_glyph):
8746 Use sprintf result rather than recomputing it.
8748 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
8749 * Makefile.in (ALL_CFLAGS):
8750 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

8775 sprintf already null-terminates its output.
8777 * xfns.c (x_window): Remove redundant cast.
8779 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
8781 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
8782 `const char *' to `char *' to avoid compiler warning.
8784 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
8786 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
8787 instead of truncating it to 63 (admittedly a generous limit).
8789 * process.c: Fix spelling and caps in comments.

8840 Remove unnecessary forward decls.
8842 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
8844 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

8846 * dispnew.c (Fsleep_for, sit_for):
8847 * keyboard.c (kbd_buffer_get_event):
8848 * process.c (Faccept_process_output):
8849 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
8850 This improves on the previous patch, which introduced a bug
8851 when time_t is unsigned and as wide as intmax_t.
8852 See <http://bugs.gnu.org/9000#51>.
8854 2012-06-23 Eli Zaretskii <eliz@gnu.org>
8856 * dispnew.c (sit_for, Fsleep_for):
8857 * keyboard.c (kbd_buffer_get_event):

8871 Privately reported by Herbert J. Skuhra.
8872 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
8874 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
8875 not make_lisp_timeval, when the argument is of type EMACS_TIME.
8877 2012-06-23 Eli Zaretskii <eliz@gnu.org>
8879 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
8880 last argument of make_unibyte_string.
8882 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
8883 language ID in the event parameters.
8885 * w32term.c (w32_read_socket): Put the new keyboard codepage into
8886 event.code, not the obscure "character set ID".

8909 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
8910 Privately reported by Herbert J. Skuhra.

8917 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
8919 Support higher-resolution time stamps (Bug#9000).
8920 The time stamps are only nanosecond-resolution at the C level,
8921 since that's the best that any real-world system supports now.
8922 But they are picosecond-resolution at the Lisp level, as that's
8923 easy, and leaves room for future OS improvements.
8925 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
8928 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
8929 Don't get current time unless it's needed.
8931 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
8932 now provides it if it's absent.
8933 (start_atimer): Port to higher-res time stamps.
8934 Check for time stamp overflow. Don't get current time more
8935 often than is needed.
8937 * buffer.h (struct buffer): Buffer modtime now has high resolution.
8938 Include systime.h, not time.h.
8939 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
8941 * dired.c: Include stat-time.h.
8942 (Ffile-attributes): File times now have higher resolution.

8945 (struct image): Timestamp now has higher resolution.
8947 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
8948 has at least microseconds now. All uses removed.
8949 (update_frame, update_single_window, update_window, update_frame_1)
8950 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
8951 (duration_to_sec_usec): Remove; no longer needed.
8953 * editfns.c (time_overflow): Now extern.
8954 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
8955 (float-time, Fformat_time_string, Fcurrent_time_string)

8959 (decode_time_components, lisp_seconds_argument): New functions.
8960 (make_time): Now static.
8961 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
8962 Report an error if the time is invalid, rather than having the caller
8965 * fileio.c: Include <stat-time.h>
8966 (Fcopy_file): Copy higher-resolution time stamps.
8967 Prefer to set the time stamp via a file descriptor if that works.
8968 (Fset_file_times, Finsert_file_contents, Fwrite_region)
8969 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
8970 (Fvisited_file_modtime, Fset_visited_file_modtime):
8971 Support higher-resolution time stamps.
8973 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
8975 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
8977 * image.c (prepare_image_for_display, clear_image_cache)
8978 (lookup_image): Port to higer-resolution time stamps.
8980 * keyboard.c (start_polling, bind_polling_period):
8981 Check for time stamp overflow.
8982 (read_char, kbd_buffer_get_event, timer_start_idle)
8983 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
8984 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
8985 Port to higher-resolution time stamps. Do not assume time_t is signed.
8986 (decode_timer): New function. Timers are now vectors of length 9,
8987 not 8, to accommodate the picosecond component.
8988 (timer_check_2): Use it.
8990 * nsterm.m (select_timeout, timeval_subtract): Remove.
8991 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
8992 as they're a bit more accurate and handle overflow better.
8993 (ns_select): Change prototype to be compatible with pselect.
8994 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
8995 * nsterm.h (ns_select): Adjust prototype.
8997 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
8998 us-resolution time stamps.
8999 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
9001 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
9003 * lisp.h (time_overflow): New decl.
9004 (wait_reading_process_output): First arg is now intmax_t, not int,
9005 to accommodate larger waits.
9007 * process.h (struct Lisp_Process.read_output_delay):
9008 Now counts nanoseconds, not microseconds.
9009 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
9011 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
9012 (wait_reading_process_output):
9013 Port to ns-resolution time stamps.
9014 (Faccept_process_output, wait_reading_process_output):
9015 Check for time stamp overflow. Do not assume time_t is signed.
9016 (select_wrapper): Remove; we now use pselect.
9017 (Fprocess_attributes): Now generates ns-resolution time stamps.
9019 * sysdep.c: Include utimens.h. Don't include utime.h
9020 or worry about struct utimbuf; gnulib does that for us now.
9021 (gettimeofday): Remove; gnulib provides a substitute.
9022 (make_timeval): New function.
9023 (set_file_times): Now sets ns-resolution time stamps.
9024 New arg FD; all uses changed.
9025 (time_from_jiffies, ltime_from_jiffies, get_up_time)
9026 (system_process_attributes):
9027 Now returns ns-resolution time stamp. All uses changed.
9028 Check for time stamp overflow.
9030 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
9031 provides a substitute now.
9033 * systime.h: Include timespec.h rather than sys/time.h and time.h,
9034 since it guarantees struct timespec.
9035 (EMACS_TIME): Now struct timespec, so that we can support
9036 ns-resolution time stamps.
9037 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
9038 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
9039 (EMACS_USECS): Remove.
9040 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
9041 so multiply the arg by 1000 before storing it.
9042 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
9044 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
9045 Port to ns-resolution time stamps.
9046 (EMACS_TIME_NEG_P): Remove; replaced by....
9047 (EMACS_TIME_SIGN): New macro.
9048 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
9049 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
9050 (set_file_times, make_time, lisp_time_argument): Adjust signature.
9051 (make_timeval, make_lisp_time, decode_time_components): New decls.
9052 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
9053 that it mishandled time_t overflow. You can't compare by subtracting!
9054 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9055 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
9057 * term.c: Include <sys/time.h>.
9058 (timeval_to_Time): New function, for proper overflow wraparound.
9059 (term_mouse_position, term_mouse_click): Use it.
9061 * undo.c (record_first_change): Support higher-resolution time stamps
9063 (Fprimitive_undo): Use them when restoring time stamps.
9065 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
9066 (w32_get_internal_run_time):
9067 Port to higher-resolution Emacs time stamps.
9068 (ltime): Now accepts single 64-bit integer, as that's more convenient

9094 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9095 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,

9147 gets killed during executing of this function (Bug#11665).
9148 Try to always return Qt when the buffer has been actually killed.

9177 argument were confusing, as 'eassert' typically does not evaluate
9180 * coding.c (produce_chars): Use ptrdiff_t, not int.
9182 * xterm.c (x_draw_underwave): Check for integer overflow.
9183 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

9368 code works fine either way, and efficiency is not a concern here,
9369 as the union type is for debugging, not for production.
9370 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
9371 Use an inline function on all platforms when using the union type,
9372 since this is simpler and 'static inline' can be used portably

9487 Block-based vector allocation of small vectors.

9516 * doprnt.c (doprnt): Truncate multibyte char correctly.
9517 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9518 would mishandle a string argument "Xc" if X was a multibyte
9519 character of length 2: it would truncate after X's first byte
9520 rather than including all of X.

9547 2012-06-03 Chong Yidong <cyd@gnu.org>
9549 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
9550 (note_mode_line_or_margin_highlight): If there is no help echo,
9551 use mode-line-default-help-echo. Handle the case where the mouse
9552 position is past the end of the mode line string.
9554 * buffer.c (buffer_local_value_1): New function, split from
9555 Fbuffer_local_value; can return Qunbound.

9566 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
9567 and DEFVAR it. Update all users.
9569 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
9571 * minibuf.c (Fassoc_string): Remove duplicate declaration.
9573 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
9574 Convert pctcpu and pctmem to Lisp float properly.
9575 Let the compiler fold better, as 100.0/0x8000 is exact.
9577 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
9579 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
9582 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
9584 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
9586 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
9588 For a 'struct window', replace some Lisp_Object fields to
9589 bitfields where appropriate, remove unused fields.
9590 * window.h (struct window): Remove unused 'last_mark_x' and
9591 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
9592 change its type from Lisp_Object to bitfield.
9593 Change type of 'force_start', 'optional_new_start',
9594 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
9595 fields from Lisp_Object to bitfield. Adjust users accordingly.
9597 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9599 Pacify gcc -Wdouble-precision when using Xaw.
9600 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
9601 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
9602 Use 'float' consistently, rather than 'float' in most places
9603 and 'double' in a couple of places.
9605 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9607 * xdisp.c (handle_stop): Detect whether we have overlay strings
9608 loaded by testing it->current.overlay_string_index to be
9609 non-negative, instead of checking whether n_overlay_strings is
9610 positive. (Bug#11587)
9612 2012-05-31 Chong Yidong <cyd@gnu.org>
9614 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
9616 * doc.c (Fsubstitute_command_keys): Doc fix.
9618 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9620 * search.c (search_buffer): Remove calls to
9621 r_alloc_inhibit_buffer_relocation, as it is now called by
9622 maybe_unify_char, which was the cause of relocation of buffer text
9625 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9627 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9628 for the duration of call to load_charset, to avoid problems with
9629 callers of maybe_unify_char that access buffer text through C
9632 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
9633 decrement the inhibition flag, instead of just setting or
9636 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9638 Remove obsolete '#define static' cruft.
9639 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
9640 This #undef was "temporary" in 2000; it is no longer needed
9641 now that '#define static' has gone away.
9642 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
9643 (gray_bitmap_bits): Remove; no longer needed.
9644 All uses replaced with definiens.
9645 * xterm.c: Include "bitmaps/gray.xbm".
9647 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
9649 Clean up __executable_start, monstartup when --enable-profiling.
9650 The following changes affect the code only when profiling.
9651 * dispnew.c (__executable_start): Rename from safe_bcopy.
9652 Define only on platforms that need it.
9653 * emacs.c: Include <sys/gmon.h> when profiling.
9654 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
9655 (__executable_start): Remove decl, since lisp.h does it now.
9656 (safe_bcopy): Remove decl; no longer has that name.
9657 (main): Coalesce #if into single bit of code, for simplicity.
9658 Cast pointers to uintptr_t, since standard libraries want integers
9660 * lisp.h (__executable_start): New decl.
9662 2012-05-31 Glenn Morris <rgm@gnu.org>
9664 * image.c (Fimagemagick_types): Doc fix.
9666 2012-05-30 Jim Meyering <meyering@redhat.com>
9668 * callproc.c (Fcall_process_region): Include directory component
9669 in mkstemp error message (Bug#11586).

9683 * lread.c (read1): Tiny simplification.
9685 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
9687 Do not create empty overlays with the evaporate property (Bug#9642).
9688 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9689 Bug#9642, but explicitly check that the buffer the overlay would
9690 be moved to is live and rearrange lines to make sure that errors
9691 will not put the overlay in an inconsistent state.
9692 (Fdelete_overlay): Cosmetics.
9694 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9696 * w32term.c (my_bring_window_to_top): New function.
9697 (x_raise_frame): Use handle returned by DeferWindowPos, which
9698 could be different from the original one.

9702 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
9703 by calling BringWindowToTop.
9705 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
9706 (WM_EMACS_END): Increase by one.
9708 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
9710 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
9711 This avoids undefined behavior that might cause the eassert
9712 to not catch an out-of-range value.
9714 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
9716 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
9717 Update dependencies.
9719 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9721 * bidi.c (bidi_mirror_char): Fix last change.
9723 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
9725 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
9726 when referring to sectname field in printf format.
9728 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
9730 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
9731 Only r_alloc_inhibit_buffer_relocation needed to be added;
9732 the others were already declared.
9734 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
9735 before checking whether it's out of range. Put the check inside
9737 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
9739 2012-05-27 Ken Brown <kbrown@cornell.edu>
9741 * callproc.c (Fcall_process): Restore a line that was accidentally
9742 commented out in the 2011-02-13 change (bug#11547).
9744 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9746 * lisp.h [REL_ALLOC]: Add prototypes for external functions
9747 defined on ralloc.c.
9749 * buffer.c [REL_ALLOC]: Remove prototypes of
9750 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
9751 they are now on lisp.h.
9753 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
9755 * search.c (search_buffer): Use it to inhibit relocation of buffer
9756 text while re_search_2 is doing its job, because re_search_2 is
9757 passed C pointers to buffer text. (Bug#11519)
9759 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
9762 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
9763 state after an additional call to move_it_in_display_line_to, keep
9764 the values of it->max_ascent and it->max_descent found for the
9766 (pos_visible_p): Revert the comparison against bottom_y to what it
9767 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
9770 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9772 Fix coding-related core dumps with gcc -ftrapv.
9773 The code was computing A - B, where A and B are pointers, and B is
9774 random garbage. This can lead to core dumps on platforms that
9775 have special pointer registers, and it also leads to core dumps on
9776 x86-64 when compiled with gcc -ftrapv. The fix is to compute
9777 A - B only when B is initialized properly.
9778 * coding.c (coding_set_source, coding_set_destination): Return void.
9779 (coding_change_source, coding_change_destinations): New functions,
9780 with the old behaviors of coding_set_source and coding_set_destination.
9781 All callers that need an offset changed to use these new functions.
9783 2012-05-26 Glenn Morris <rgm@gnu.org>
9785 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
9787 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9789 Extend mouse support on W32 text-mode console.
9790 * xdisp.c (draw_row_with_mouse_face):
9791 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
9793 * w32console.c: Include window.h.
9794 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
9796 (initialize_w32_display): Initialize mouse-highlight data.
9798 * w32inevt.c: Include termchar.h and window.h.
9799 (do_mouse_event): Support mouse-autoselect-window. When the mouse
9800 moves, call note_mouse_highlight. If help_echo changed, call
9801 gen_help_event to produce help-echo message in the echo area.
9802 Call clear_mouse_face if mouse_face_hidden is set in the mouse
9805 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9807 * lread.c (read1): Simplify slightly to avoid an overflow warning
9808 with GCC 4.7.0 on x86-64.
9810 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9812 * bidi.c (bidi_mirror_char): Revert last change: an int is
9813 definitely wide enough here.
9815 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
9817 Fix integer width and related bugs (Bug#9874).
9818 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
9819 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
9820 (string_bytes, check_sblock, allocate_string_data):
9821 (compact_small_strings, Fmake_bool_vector, make_string)
9822 (make_unibyte_string, make_multibyte_string)
9823 (make_string_from_bytes, make_specified_string)
9824 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
9825 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
9827 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9828 (allocate_pseudovector):
9829 Use int, not EMACS_INT, where int is wide enough.
9830 (inhibit_garbage_collection, Fgarbage_collect):
9831 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9832 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
9833 int might not be wide enough.
9834 (bidi_cache_search, bidi_cache_find, bidi_init_it)
9835 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
9836 (bidi_at_paragraph_end, bidi_find_paragraph_start)
9837 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
9838 (bidi_level_of_next_char, bidi_move_to_visually_next):
9839 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9840 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
9841 (Fkill_buffer, Fset_buffer_major_mode)
9842 (advance_to_char_boundary, Fbuffer_swap_text)
9843 (Fset_buffer_multibyte, overlays_at, overlays_in)
9844 (overlay_touches_p, struct sortvec, record_overlay_string)
9845 (overlay_strings, recenter_overlay_lists)
9846 (adjust_overlays_for_insert, adjust_overlays_for_delete)
9847 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
9848 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
9849 (Foverlay_recenter, last_overlay_modification_hooks_used)
9850 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
9851 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9852 (validate_region): Omit unnecessary test for b <= e,
9853 since that's guaranteed by the previous test.
9854 (adjust_overlays_for_delete): Avoid pos + length overflow.
9855 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
9856 (report_overlay_modification):
9857 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9858 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
9859 Omit pointer cast, which isn't needed anyway, and doesn't work
9860 after the EMACS_INT -> ptrdiff_t change.
9861 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
9862 * buffer.h: Adjust decls to match defn changes elsewhere.
9863 (struct buffer_text, struct buffer):
9864 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9865 Use EMACS_INT, not int, where int might not be wide enough.
9866 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
9867 not int, to avoid needless 32-bit limit on 64-bit hosts.
9868 (exec_byte_code): Use tighter memory-full test, one that checks
9869 for alloca overflow. Don't compute the address of the object just
9870 before an array, as that's not portable. Use EMACS_INT, not
9871 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
9872 * callint.c (Fcall_interactively):
9873 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9874 * callproc.c (call_process_kill, Fcall_process):
9875 Don't assume pid_t fits into an Emacs fixnum.
9876 (call_process_cleanup, Fcall_process, child_setup):

9878 (call_process_cleanup, Fcall_process, delete_temp_file)
9879 (Fcall_process_region):
9880 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9881 (Fcall_process): Simplify handling of volatile integers.
9882 Use int, not EMACS_INT, where int will do.
9883 * casefiddle.c (casify_object, casify_region, operate_on_word)
9884 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
9885 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9886 (casify_object): Avoid integer overflow when overallocating buffer.
9887 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
9888 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
9889 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
9890 * category.h (CATEGORYP): Don't assume arg is nonnegative.
9891 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
9892 integers are now checked earlier. All uses replaced with XINT.
9894 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9895 For CCL_MapSingle, check that content and value are in int range.
9896 (ccl_driver, Fregister_code_conversion_map):
9897 Check that Vcode_version_map_vector is a vector.
9898 (resolve_symbol_ccl_program): Check that vector header is in range.
9899 Always copy the vector, so that we can check its contents reliably
9900 now rather than having to recheck each instruction as it's being
9901 executed. Check that vector words fit in 'int'.
9902 (ccl_get_compiled_code, Fregister_ccl_program)
9903 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
9904 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
9905 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
9906 contents are in range.
9907 (Fccl_execute_on_string): Check that status is in range.
9908 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
9909 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
9910 Accept and return EMACS_INT, not int, because callers can pass values
9912 (c_string_width, strwidth, lisp_string_width, chars_in_text)
9913 (multibyte_chars_in_text, parse_str_as_multibyte)
9914 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
9915 (str_as_unibyte, str_to_unibyte, string_count_byte8)
9916 (string_escape_byte8, Fget_byte):
9917 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9918 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
9919 avoid mishandling large integers.
9920 * character.h: Adjust decls to match defn changes elsewhere.
9921 * charset.c (load_charset_map_from_file, find_charsets_in_text)
9922 (Ffind_charset_region):
9923 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9924 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
9925 (load_charset_map_from_vector, Fdefine_charset_internal):
9926 Don't assume fixnum fits in int.
9927 (load_charset_map_from_vector, Fmap_charset_chars):
9928 Remove now-unnecessary CHECK_NATNUMs.
9929 (Fdefine_charset_internal): Check ranges here, more carefully.
9930 Don't rely on undefined behavior with signed left shift overflow.
9931 Don't assume unsigned int fits into fixnum, or that fixnum fits
9932 into unsigned int. Don't require max_code to be a valid fixnum;
9933 that's not true for gb10830 4-byte on a 32-bit host. Allow
9934 invalid_code to be a cons, for the same reason. Require code_offset
9935 to be a character. Avoid int overflow if max_char is close
9937 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
9938 this is intended anyway and avoids some undefined behavior.
9939 (load_charset_map): Pass unsigned, not int, as 2nd arg of
9940 INDEX_TO_CODE_POINT, as that's what it expects.
9941 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
9942 * charset.h (DECODE_CHAR): Return int, not unsigned;
9943 this is what was intended anyway, and it avoids undefined behavior.
9944 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
9945 integer-overflow issues.
9946 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
9947 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
9948 where the argument is EMACS_INT, and this behavior is not intended.
9949 * chartab.c (Fmake_char_table, Fset_char_table_range)
9950 (uniprop_get_decoder, uniprop_get_encoder):
9951 Don't assume fixnum fits in int.
9952 * cmds.c (move_point): New function, that does the gist of
9953 Fforward_char and Fbackward_char, but does so while checking
9954 for integer overflow more accurately.
9955 (Fforward_char, Fbackward_char): Use it.
9956 (Fforward_line, Fend_of_line, internal_self_insert)
9957 (internal_self_insert):
9958 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9959 Fix a FIXME, by checking for integer overflow when calculating
9960 target_clm and actual_clm.
9961 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)
9962 (CODING_ENCODE_CHAR, CODING_CHAR_CHARSET, CODING_CHAR_CHARSET_P)
9963 (ASSURE_DESTINATION, coding_alloc_by_realloc)

10651 * lisp.h (USE_LSB_TAG):
10652 * mem-limits.h (EXCEEDS_LISP_PTR):
10653 Use VAL_MAX, not VALBITS, in #if.
10654 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
10655 (EMACS_UINT): Define unconditionally now.
10656 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
10657 (BITS_PER_EMACS_INT): New constants, replacing
10658 what used to be in config.h, but not useful in #if.
10659 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
10660 define them any more.
10661 (VAL_MAX): New macro.
10663 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
10664 BITS_PER_EMACS_INT, in #if.
10665 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
10666 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
10667 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
10668 * s/ms-w32.h (DATA_START):
10669 Move here from removed file m/intel386.h.
10670 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
10671 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
10673 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
10675 Assume C89 or later.
10676 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
10677 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
10679 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
10680 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
10681 * textprop.c, tparam.c (NULL): Remove.
10682 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
10683 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
10684 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
10685 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
10686 * xterm.c (input_signal_count): Assume volatile works.
10688 2012-05-21 Ken Brown <kbrown@cornell.edu>
10690 * xgselect.c (xg_select): Fix first argument in call to 'select'
10693 2012-05-20 Ken Brown <kbrown@cornell.edu>
10695 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
10696 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
10698 2012-05-19 Ken Brown <kbrown@cornell.edu>
10700 * xfns.c (x_in_use): Remove `static' qualifier.
10701 * xterm.h (x_in_use): Declare.
10702 * xgselect.c: Include xterm.h.
10703 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
10704 and `display_arg' (bug#9754).
10706 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
10708 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
10710 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
10711 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
10713 2012-05-18 Eli Zaretskii <eliz@gnu.org>
10715 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
10717 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
10718 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
10720 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
10721 reference to image_cache->refcount.
10722 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
10724 2012-05-17 Juri Linkov <juri@jurta.org>
10726 * search.c (Fword_search_regexp, Fword_search_backward)
10727 (Fword_search_forward, Fword_search_backward_lax)
10728 (Fword_search_forward_lax): Move functions to isearch.el
10729 (bug#10145, bug#11381).
10731 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
10733 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
10735 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
10737 * lread.c (init_obarray): Declare Qt and Qnil as special.
10739 2012-05-14 Glenn Morris <rgm@gnu.org>
10741 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
10742 Put "libexec" before "bin", for the sake of init_callproc_1.
10744 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10746 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
10748 * unexaix.c: Port to more-recent AIX compilers.
10749 (report_error, report_error_1, make_hdr, copy_sym)
10750 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
10751 Make arguments const char *, not char *, to avoid violations of C
10752 standard and to fix some AIX warnings reported by Gilles Pion.
10754 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10756 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
10757 already have overlays loaded.
10758 (handle_single_display_spec): Before returning without displaying
10759 fringe bitmap, synchronize the bidi iterator with the main display
10760 iterator, by calling iterate_out_of_display_property.
10761 (iterate_out_of_display_property): Detect buffer iteration by
10762 testing that it->string is a Lisp string.
10763 (get_next_display_element): When the current object is exhausted,
10764 and there's something on it->stack, call set_iterator_to_next to
10765 proceed with what's on the stack, instead of returning zero.
10766 (set_iterator_to_next): If called at the end of a Lisp string,
10767 proceed to consider_string_end without incrementing string
10768 position. Don't increment display vector index past the end of
10769 the display vector. (Bug#11417)
10770 (pos_visible_p): Don't report a position visible when move_it_to
10771 stopped at the last line of window, which happens to be scanned
10772 backwards by the bidi iteration. (Bug#11464)
10774 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10776 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
10777 and right-margin display specs even if the spec is invalid or we
10778 are on a TTY, and thus unable to display on the fringes.
10779 That's because the text with the property will not be displayed anyway,
10780 so we need to signal to the caller that this is a "replacing"
10781 display spec. This fixes display when the spec is invalid or we
10784 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10786 * unexaix.c (make_hdr): Fix typo in prototype.
10787 This bug broke the build on AIX. Problem reported by Gilles Pion.
10789 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
10791 * keyboard.c (kbd_buffer_get_event): Read special events also in
10792 batch mode. (Bug#11415)
10794 2012-05-12 Glenn Morris <rgm@gnu.org>
10796 * ns.mk: Update for ns_appbindir no longer having trailing "/".
10798 2012-05-12 Eli Zaretskii <eliz@gnu.org>
10800 * lisp.mk (lisp): Add newcomment.elc.
10802 2012-05-12 Glenn Morris <rgm@gnu.org>
10804 * Makefile.in (MKDIR_P): New, set by configure.
10805 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
10807 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
10809 Remove unused function hourglass_started.
10810 * dispextern.h (hourglass_started):
10811 * w32fns.c (hourglass_started):
10812 * xdisp.c (hourglass_started): Remove.
10814 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
10816 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
10817 Update dependencies.
10819 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
10821 * xgselect.c (xg_select): Put maxfds+1 into a var.
10822 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
10824 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
10826 2012-05-10 Dave Abrahams <dave@boostpro.com>
10828 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
10829 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
10831 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
10833 * dbusbind.c (xd_registered_buses): New internal Lisp object.
10834 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
10835 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
10836 Initialize xd_registered_buses.
10838 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
10840 Untag more efficiently if USE_LSB_TAG.
10841 This is based on a proposal by YAMAMOTO Mitsuharu in
10842 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
10843 For an admittedly artificial (nth 8000 longlist) benchmark on
10844 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
10845 Emacs's overall text size by 1%.
10846 * lisp.h (XUNTAG): New macro.
10847 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
10848 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
10849 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
10850 * eval.c (Fautoload):
10851 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
10852 * frame.h (XFRAME): Use XUNTAG.
10854 Port recent dbusbind.c changes to 32-bit --with-wide-int.
10855 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
10856 Remove unportable assumptions about print widths of types like
10858 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
10859 intptr_t when converting between pointer and integer, to avoid GCC
10860 warnings about wrong width.
10862 2012-05-09 Eli Zaretskii <eliz@gnu.org>
10864 * w32proc.c (new_child): Force Windows to reserve only 64KB of
10865 stack for each reader_thread, instead of defaulting to 8MB
10866 determined by the linker. This avoids failures in creating
10867 subprocesses on Windows 7, see the discussion in this thread:
10868 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
10870 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
10872 Fix up display of the *Minibuf-0* buffer in the mini window.
10873 * keyboard.c (read_char): Don't clear the echo area if there's no
10875 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
10876 contents of *Minibuf-0*) if there's no message displayed in its stead.
10878 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
10880 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
10883 2012-05-06 Chong Yidong <cyd@gnu.org>
10885 * lisp.mk (lisp): Update.
10887 2012-05-05 Jim Meyering <meyering@redhat.com>
10889 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
10891 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
10893 * data.c (PUT_ERROR): New macro.
10894 (syms_of_data): Use it. Add new error type `user-error'.
10895 * undo.c (user_error): New function.
10896 (Fprimitive_undo): Use it.
10897 * print.c (print_error_message): Adjust print style for `user-error'.
10898 * keyboard.c (user_error): New function.
10899 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
10901 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
10903 Do not limit current-time-string to years 1000..9999.
10904 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
10905 (Fcurrent_time_string): Support any year that is supported by the
10906 underlying localtime representation. Don't use asctime, as it
10907 has undefined behavior for years outside the range -999..9999.
10909 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
10911 Fix race conditions involving setenv, gmtime, localtime, asctime.
10912 Without this fix, interrupts could mess up code that uses these
10913 nonreentrant functions, since setting TZ invalidates existing
10914 tm_zone or tzname values, and since most of these functions return
10915 pointers to static storage.
10916 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
10917 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
10918 Grow the critical sections to include not just invoking
10919 localtime/gmtime, but also accessing these functions' results
10920 including their tm_zone values if any, and any related TZ setting.
10921 (format_time_string): Last arg is now struct tm *, not struct tm **,
10922 so that the struct tm is saved in the critical section.
10923 All callers changed. Simplify allocation of initial buffer, partly
10924 motivated by the fact that memory allocation needs to be outside
10925 the critical section.
10927 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
10929 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
10930 with RESET_INTERVAL.
10932 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
10933 Remove duplicated buffer name initialization.
10935 2012-05-02 Jim Meyering <jim@meyering.net>
10937 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
10939 * xfns.c (x_window): Use xstrdup (Bug#11375).
10941 2012-05-02 Eli Zaretskii <eliz@gnu.org>
10943 * xdisp.c (pos_visible_p): If already at a newline from the
10944 display string before the 'while' loop, don't walk back the glyphs
10945 from it3.glyph_row. Solves assertion violation when the display
10946 string begins with a newline (egg.el). (Bug#11367)
10948 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
10950 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
10953 2012-05-01 Glenn Morris <rgm@gnu.org>
10955 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
10956 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
10957 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
10958 All were removed before 23.1.
10960 * dispnew.c: Remove HAVE_LIBNCURSES test;
10961 it is always true on relevant platforms.
10963 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
10964 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
10966 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
10968 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
10970 * .gdbinit (xpr): Remove checks for no longer existing misc types.
10971 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
10974 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
10976 Do not avoid creating empty evaporating overlays (Bug#9642).
10977 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
10978 That is, do not delete an evaporating overlay if it becomes
10979 empty after its bounds are adjusted to fit within its buffer.
10980 This fix caused other problems, and I'm reverting it until we get
10981 to the bottom of them.
10983 2012-04-27 Chong Yidong <cyd@gnu.org>
10985 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
10987 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10989 * xdisp.c (pos_visible_p): If the window start position is beyond
10990 ZV, start the display from buffer beginning. Prevents assertion
10991 violation in init_iterator when the minibuffer window is scrolled
10992 via the scroll bar.
10994 * window.c (window_scroll_pixel_based): Likewise.
10996 2012-04-27 Chong Yidong <cyd@gnu.org>
10998 * keymap.c (where_is_internal): Doc fix (Bug#10872).
11000 2012-04-27 Glenn Morris <rgm@gnu.org>
11002 * fileio.c (Fcopy_file, Fset_file_selinux_context):
11003 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
11005 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11007 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
11008 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
11010 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11012 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11013 display element, check also the underlying string or buffer
11014 character. (Bug#11341)
11016 * w32menu.c: Include w32heap.h.
11017 (add_menu_item): If the call to AppendMenuW (via
11018 unicode_append_menu) fails, disable Unicode menus only if we are
11019 running on Windows 9X/Me.
11021 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
11023 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
11024 (xgetint): Add missing shift for LSB tags.
11026 2012-04-24 Martin Rudalics <rudalics@gmx.at>
11028 * keyboard.c (read_char): Don't wipe echo area for select window
11029 events: These might get delayed via `mouse-autoselect-window'
11032 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
11034 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
11035 manipulation of :loaded-from data.
11037 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
11039 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
11040 now a cons (bug#11311).
11042 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
11044 Do not create empty overlays with the evaporate property (Bug#9642).
11045 * buffer.c (Fmove_overlay): Delete an evaporating overlay
11046 if it becomes empty after its bounds are adjusted to fit within
11047 its buffer. Without this fix, in a nonempty buffer (let ((o
11048 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11049 yields an empty overlay that has the evaporate property, which is
11050 not supposed to happen.
11052 Fix minor GTK3 problems found by static checking.
11053 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11054 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11055 (struct _EmacsFixedClass, emacs_fixed_get_type):
11056 Move decls here from emacsgtkfixed.h, since they needn't be public.
11057 (emacs_fixed_get_type): Now static.
11058 (emacs_fixed_class_init): Omit unused local.
11059 (emacs_fixed_child_type): Remove; unused.
11060 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11061 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11062 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
11063 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
11064 (EMACS_FIXED_GET_CLASS): Remove; unused.
11065 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
11067 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
11068 Problem reported by Juanma Barranquero for Windows -Wunused-function.
11070 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11072 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
11073 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
11074 (__malloc_size_t, __malloc_ptrdiff_t):
11075 Remove. All uses removed, replaced by the definiens if needed,
11076 since we can assume C89 or better now.
11077 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

11085 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)

11165 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11167 * sysdep.c [__FreeBSD__]: Minor cleanups.
11168 (list_system_processes, system_process_attributes) [__FreeBSD__]:
11169 Use Emacs indenting style more consistently. Avoid some casts.

11188 * print.c (print_preprocess): Only check print_depth if print-circle
11190 (print_object): Check for cycles even when print-circle is nil and

11253 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
11254 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
11255 (NEED_MEM_INSERT): New macro.
11256 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
11257 Remove one incorrect comment and fix another.

11293 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
11294 * s/netbsd.h, s/sol2-6.h:
11295 Remove definition of GC_MARK_STACK, since the default now works.
11296 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

11324 2012-04-11 Daniel Colascione <dancol@dancol.org>
11326 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
11327 against is gone. It's better to use vfork now so that when Cygwin
11328 gains a new, working vfork, we use it automatically (bug#10398).
11330 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

11351 being loaded (bug#10424).
11353 2012-04-09 Glenn Morris <rgm@gnu.org>
11355 * doc.c (Fsnarf_documentation): Check variables, functions are bound,

11383 * minibuf.c (Fread_variable): Callers changed.
11385 2012-04-09 Eli Zaretskii <eliz@gnu.org>
11387 * xdisp.c (set_cursor_from_row): If the display string appears in
11388 the buffer at position that is closer to point than the position
11389 after the display string, display the cursor on the first glyph of
11390 the display string. Fixes cursor display when a 'display' text
11391 property immediately follows invisible text. (Bug#11094)
11393 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11395 composite.c: use 'double' consistently
11396 * composite.c (get_composition_id): Use 'double' consistently
11397 instead of converting 'float' to 'double' and vice versa; this is
11398 easier to understand and avoids a GCC warning.
11400 2012-04-09 Glenn Morris <rgm@gnu.org>
11402 * Makefile.in: Generate leim-list with bootstrap-emacs, in

11447 [!WINDOWSNT]: New macros.
11448 (init_libxml2_functions, libxml2_loaded_p): New functions.

11452 Calls xmlCleanupParser only if libxml2 was loaded (or statically
11454 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
11455 Call init_libxml2_functions before calling libxml2 functions.

11464 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11466 * indent.c (Fvertical_motion): If there is a display string at
11467 point, use it.vpos to compute how many lines to backtrack after
11468 move_it_to point. (Bug#11133)
11470 2012-04-06 Eli Zaretskii <eliz@gnu.org>
11472 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
11473 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
11474 about subtle differences between FETCH_CHAR* and STRING_CHAR*
11475 macros related to unification of CJK characters. For the details,
11476 see the discussion following the message here:
11477 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.

11493 2012-03-31 Eli Zaretskii <eliz@gnu.org>
11495 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
11496 position we get to after a call to move_it_to fails the
11497 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
11498 only if we wind up in a string from display property. (Bug#11063)
11500 * window.c (Fdelete_other_windows_internal): Invalidate the row
11501 and column information about mouse highlight, so that redisplay
11502 restores it after reallocating the glyph matrices. (Bug#7464)
11504 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
11505 string comes from a `display' text property, use the buffer
11506 position of that property as if we actually saw that position in
11508 (move_it_by_lines): Remove the assertion that
11509 "it->current_x == 0 && it->hpos == 0" which can be legitimately
11510 violated when there's a before-string at the beginning of a line.

11519 (display_line): Call extend_face_to_end_of_line when the default
11520 face was remapped. (Bug#11068)

11530 2012-03-27 Glenn Morris <rgm@gnu.org>
11532 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
11535 2012-03-26 Kenichi Handa <handa@m17n.org>
11537 * dispextern.h (struct glyph): Fix previous change. Change the
11538 bit length of glyphless.ch to 25 (Bug#11082).
11540 2012-03-26 Chong Yidong <cyd@gnu.org>
11542 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11543 (command_loop_1): Use it; inhibit selection update for
11544 handle-select-window too (Bug#8996).
11546 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
11548 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
11550 2012-03-25 Kenichi Handa <handa@m17n.org>
11552 * dispextern.h (struct glyph): Change the bit length of
11553 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11555 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11557 * s/ms-w32.h (tzname): Include time.h before redirecting to
11558 _tzname. Fixes the MSVC build. (Bug#9960)
11560 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
11562 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
11565 * xterm.c (XTread_socket): Only modify handling_signal if
11566 !SYNC_INPUT. (Bug#11080)
11568 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11570 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11571 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11572 when fetching a multibyte character consumes more bytes than
11573 CHAR_BYTES returns, due to unification of CJK characters in
11574 string_char. (Bug#11073)
11576 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11578 * process.c (wait_reading_process_output): Handle pty disconnect
11579 by refraining from sending oneself a SIGCHLD (bug#10933).
11581 2012-03-22 Chong Yidong <cyd@gnu.org>

11585 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
11586 Mark string as coming from a prefix property.
11587 (handle_face_prop): Use default face for prefix strings (Bug#4281).
11588 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
11590 2012-03-21 Chong Yidong <cyd@gnu.org>
11592 * xfaces.c (Vface_remapping_alist): Doc fix.

11602 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
11603 to reflect default non-nil value of redisplay-dont-pause.
11605 2012-03-19 Kenichi Handa <handa@m17n.org>
11607 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
11608 it fit in a valid range (Bug#11003).
11610 2012-03-18 Eli Zaretskii <eliz@gnu.org>
11612 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
11613 that is not from display property, accept the row as a "cursor
11614 row" if one of the string's character has a non-nil `cursor'
11615 property. Fixes cursor positioning when there are newlines in
11616 overlay strings, e.g. in icomplete.el. (Bug#11035)
11618 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
11620 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
11622 2012-03-12 Chong Yidong <cyd@gnu.org>
11624 * eval.c (inhibit_lisp_code): Rename from
11625 inhibit_window_configuration_change_hook; move from window.c.
11627 * xfns.c (unwind_create_frame_1, Fx_create_frame):
11628 * window.c (run_window_configuration_change_hook)
11629 (syms_of_window): Callers changed.
11631 2012-03-11 Chong Yidong <cyd@gnu.org>
11633 * keymap.c (Fkey_description): Doc fix (Bug#9700).
11635 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
11637 2012-03-10 Chong Yidong <cyd@gnu.org>
11639 * frame.c (other_visible_frames): Don't assume the selected frame
11640 is visible (Bug#10955).
11642 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
11644 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).

11648 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
11649 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
11652 2012-03-03 Glenn Morris <rgm@gnu.org>
11654 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
11656 2012-03-02 Eli Zaretskii <eliz@gnu.org>
11658 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
11659 position past the first glyph_row that ends at ZV. (Bug#10902)
11660 (redisplay_window, next_element_from_string): Fix typos in
11662 (redisplay_window): Pass to move_it_vertically the margin in
11663 pixels, not in screen lines.
11665 2012-03-02 Glenn Morris <rgm@gnu.org>
11667 * buffer.c (buffer-list-update-hook): Doc fix.
11669 2012-02-29 Eli Zaretskii <eliz@gnu.org>
11671 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
11672 push_it before setting up the iterator for the first overlay
11673 string, even if we have an empty string loaded.
11674 (next_overlay_string): If there's an empty string on the iterator
11675 stack, pop the stack. (Bug#10903)
11677 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
11679 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
11680 Suggested by Stefan Monnier in
11681 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
11682 * alloc.c (widen_to_Lisp_Object): New static function.
11683 (mark_memory): Also mark Lisp_Objects by fetching pointer words
11684 and widening them to Lisp_Objects. This would work even if
11685 USE_LSB_TAG is defined and wide integers are used, which might
11686 happen in a future version of Emacs.
11688 2012-02-25 Chong Yidong <cyd@gnu.org>
11690 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
11693 * xselect.c (Fx_selection_exists_p): Doc fix.
11694 (x_clipboard_manager_save_all): Print an informative message
11695 before saving to clipboard manager.
11697 2012-02-24 Chong Yidong <cyd@gnu.org>
11699 * keyboard.c (process_special_events): Handle all X selection
11700 requests in kbd_buffer, not just the next one (Bug#8869).
11702 2012-02-23 Chong Yidong <cyd@gnu.org>
11704 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
11705 call when setting menu-bar-lines and tool-bar-lines parameters.
11706 (unwind_create_frame_1): New helper function.
11708 * window.c (inhibit_window_configuration_change_hook): New var.
11709 (run_window_configuration_change_hook): Obey it.
11710 (syms_of_window): Initialize it.
11712 2012-02-22 Chong Yidong <cyd@gnu.org>
11714 * xterm.c (x_draw_image_relief): Add missing type check for
11715 Vtool_bar_button_margin (Bug#10743).
11717 2012-02-21 Chong Yidong <cyd@gnu.org>
11719 * fileio.c (Vfile_name_handler_alist): Doc fix.
11721 * buffer.c (Fget_file_buffer): Protect against invalid file
11722 handler return value.
11724 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
11726 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
11727 when computing $valmask.
11729 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
11730 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
11731 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
11732 It's useless in that case, and it can cause problems on hosts
11733 that allocate halves of EMACS_INT values separately.
11734 Reported by Dan Horák. Diagnosed by Andreas Schwab in
11735 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
11736 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
11737 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
11738 it avoids undefined behavior on hosts where shifting right by more
11739 than the word width has undefined behavior.
11741 2012-02-19 Chong Yidong <cyd@gnu.org>
11743 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
11744 (Funhandled_file_name_directory, Ffile_name_as_directory)
11745 (Fdirectory_file_name, Fexpand_file_name)
11746 (Fsubstitute_in_file_name): Protect against invalid file handler
11747 return values (Bug#10845).
11749 2012-02-18 Eli Zaretskii <eliz@gnu.org>
11751 * .gdbinit (pitx): Fix incorrect references to fields of the

11761 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
11763 2012-02-15 Chong Yidong <cyd@gnu.org>
11765 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
11766 marked as special. Also, starting docstrings with * is obsolete.
11768 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
11770 * gnutls.c (emacs_gnutls_write): Fix last change.

11779 * keymap.c (Fsingle_key_description): Handle char ranges.
11781 2012-02-12 Chong Yidong <cyd@gnu.org>
11783 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
11784 as that creates a dangerous corner case.
11786 * window.c (Fdelete_window_internal): Invalidate the mouse
11787 highlight (Bug#9904).
11789 2012-02-12 Glenn Morris <rgm@gnu.org>

11792 (Fx_get_selection_internal, Fx_disown_selection_internal)
11793 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
11794 * nsselect.m (Fx_own_selection_internal)
11795 (Fx_disown_selection_internal, Fx_selection_exists_p)
11796 (Fx_selection_owner_p, Fx_get_selection_internal):
11797 Sync docs and argument specs with the xselect.c versions.
11799 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
11801 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

11819 2012-02-07 Chong Yidong <cyd@gnu.org>
11821 * buffer.c (Fbuffer_local_variables)
11822 (buffer_lisp_local_variables): Handle unbound vars correctly;
11823 don't let Qunbound leak into Lisp.
11825 2012-02-07 Glenn Morris <rgm@gnu.org>
11827 * image.c (Fimagemagick_types): Doc fix.
11829 * image.c (imagemagick-render-type): Change it from a lisp object
11830 to an integer. Move the doc here from the lisp manual.
11831 Treat all values not equal to 0 the same.
11833 2012-02-06 Chong Yidong <cyd@gnu.org>
11835 * doc.c (store_function_docstring): Avoid applying docstring of
11836 alias to base function (Bug#2603).

11843 2012-02-04 Chong Yidong <cyd@gnu.org>
11845 * nsterm.m: Declare a global (Bug#10694).
11847 2012-02-04 Eli Zaretskii <eliz@gnu.org>
11849 * w32.c (get_emacs_configuration_options):
11850 Include --enable-checking, if specified, in the return value.
11852 2012-02-04 Martin Rudalics <rudalics@gmx.at>
11854 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
11855 after rounding frame sizes. (Bug#9723)

11859 * keyboard.c (adjust_point_for_property): Don't position point
11860 before BEGV. (Bug#10696)
11862 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
11864 Handle overflow when computing char display width (Bug#9496).
11865 * character.c (char_width): Return EMACS_INT, not int.
11866 (char_width, c_string_width): Check for overflow when
11867 computing the width; this is possible now that individual
11868 characters can have unbounded width. Problem introduced
11869 by merge from Emacs 23 on 2012-01-19.
11871 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
11873 * dbusbind.c (Fdbus_register_method): Mention the return value
11874 :ignore in the docstring.

11886 2012-02-02 Kenichi Handa <handa@m17n.org>
11888 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
11889 0, do not call append_composite_glyph.
11891 2012-02-02 Kenichi Handa <handa@m17n.org>
11893 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
11895 (x_produce_glyphs): If the component of a composition is a null
11896 string, set it->pixel_width to 1 to avoid zero-width glyph.
11898 2012-02-01 Eli Zaretskii <eliz@gnu.org>
11900 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
11901 first 2 arguments are identical. This makes inserting large
11902 output from a subprocess an order of magnitude faster on
11903 MS-Windows, where all sbrk'ed memory is always contiguous.
11905 2012-01-31 Glenn Morris <rgm@gnu.org>
11907 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

11943 2012-01-21 Chong Yidong <cyd@gnu.org>
11945 * floatfns.c (Fcopysign): Make the second argument non-optional,
11946 since nil is not allowed anyway.
11948 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
11950 * process.c (read_process_output): Use p instead of XPROCESS (proc).

11957 Rewrite doc-strings.
11959 2012-01-19 Kenichi Handa <handa@m17n.org>
11961 * character.c (char_width): New function.
11962 (Fchar_width, c_string_width, lisp_string_width):
11963 Use char_width (Bug#9496).

11971 2012-01-14 Eli Zaretskii <eliz@gnu.org>
11973 * w32fns.c (signal_user_input): Don't do a QUIT, to avoid
11974 thrashing the stack of the thread. (Bug#9087)

11983 highlight ends on a newline. (Bug#10464)
11984 (mouse_face_from_buffer_pos): Fix off-by-one error in calculating
11985 he end column for display of highlight that ends on a newline
11988 2012-01-11 Glenn Morris <rgm@gnu.org>
11990 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
11991 from load-path also when installation-directory is nil. (Bug#10208)
11993 2012-01-10 Glenn Morris <rgm@gnu.org>
11995 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.
11997 * epaths.in (PATH_LOADSEARCH, PATH_EXEC, PATH_DATA, PATH_DOC):
11998 Update template values to be closer to their typical values these days.
12000 2012-01-09 Eli Zaretskii <eliz@gnu.org>
12002 * xdisp.c (rows_from_pos_range): Accept additional argument
12003 DISP_STRING, and accept any glyph in a row whose object is that
12004 string as eligible for mouse highlight. Fixes mouse highlight of
12005 display strings from overlays. (Bug#10464)
12007 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
12009 emacs: fix an auto-save permissions race condition (Bug#10400)
12010 * fileio.c (auto_saving_dir_umask): New static var.
12011 (Fmake_directory_internal): Use it.
12012 (do_auto_save_make_dir): Set it, instead of invoking chmod after
12013 creating the directory. The old code temporarily assigns
12014 too-generous permissions to the directory.

12518 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
12519 Otherwise, valgrind does not work on some platforms.
12520 Problem reported by Andreas Schwab in
12521 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
12522 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
12523 is set, removing the need for VIRT_ADDRESS_VARIES.
12524 (PURE_P): Use a more-efficient implementation that needs just one
12525 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
12526 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
12527 to 4 (xorl, subq, cmpq, setbe).
12528 * alloc.c (pure): Always extern now, since that's the
12529 VIRT_ADDR_VARIES behavior.
12530 (PURE_POINTER_P): Use a single comparison, not two, for
12531 consistency with the new puresize.h.
12532 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
12533 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

12539 (erase_phys_cursor, update_window_cursor, show_mouse_face)
12540 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
12541 behave as if the cursor position were at the window margin.
12543 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
12544 and the cursor position is out of bounds, behave as if the cursor
12545 position were at the window margin. (Bug#10075)
12547 2011-11-18 Chong Yidong <cyd@gnu.org>
12549 * window.c (Fwindow_combination_limit): Make first argument

12567 hash values of the two rows. (Bug#10035)
12568 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
12570 * xdisp.c (row_hash): New function, body extracted from
12571 compute_line_metrics.
12572 (compute_line_metrics): Call row_hash, instead of computing the
12575 * dispnew.c (verify_row_hash): Call row_hash for computing the
12576 hash code of a row, instead of duplicating code from xdisp.c.
12578 * dispextern.h (row_hash): Add prototype.
12580 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

12608 (Fsplit_window_internal, saved_window)
12609 (Fset_window_configuration, save_window_save): Rename all
12610 occurrences of window_nest to window_combination_limit.

12616 2011-11-14 Eli Zaretskii <eliz@gnu.org>
12618 * xdisp.c (display_line): Move the call to
12619 highlight_trailing_whitespace before the call to
12620 compute_line_metrics, since the latter needs to see the final
12621 faces of all the glyphs to compute ROW's hash value.
12622 Fixes assertion violations in row_equal_p. (Bug#10035)
12624 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
12626 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
12627 just return (bug#10044).
12629 2011-11-12 Eli Zaretskii <eliz@gnu.org>
12631 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
12632 with user-defined heap size. Bump the default size of the temacs
12633 heap to 27MB, to avoid memory warning when running temacs.
12634 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
12636 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
12637 current_matrix and desired_matrix. (Bug#9990)
12638 (verify_row_hash) [XASSERTS]: New function.

12683 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
12685 Avoid some portability problems by eschewing 'extern inline' functions.
12686 The trivial performance wins aren't worth the portability hassles; see
12687 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
12689 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

12755 * xmenu.c (cleanup_widget_value_tree): New function.
12756 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

12763 (window_box_width, window_box_left, window_box_left_offset)
12764 (window_box_right, window_box_right_offset): Declare extern.
12765 Otherwise, these inline functions do not conform to C99 and
12766 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
12767 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
12768 * intervals.c (adjust_intervals_for_insertion)

12771 (static_offset_intervals): Remove.
12772 (offset_intervals): Rewrite using the old contents of
12773 static_offset_intervals. The old version didn't conform to C99
12774 because an extern inline function contained a reference to an
12775 identifier with static linkage.

12939 check for _NET_WM_STATE_HIDDEN (Bug#9893).
12940 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
12941 (x_handle_net_wm_state): Return what get_current_wm_state returns.
12942 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
12944 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
12946 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
12947 so that this new function doesn't get optimized away by a
12948 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
12950 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
12952 * frame.h (MOUSE_HL_INFO): Remove excess parens.
12954 2011-10-29 Eli Zaretskii <eliz@gnu.org>
12956 Fix the `xbytecode' command.
12957 * .gdbinit (xprintbytestr): New command.
12958 (xwhichsymbols): Rename from `which'; all callers changed.
12959 (xbytecode): Print the byte-code string as well.
12961 2011-10-29 Kim Storm <storm@cua.dk>
12963 * alloc.c (which_symbols): New function.
12965 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
12967 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
12970 2011-10-29 Glenn Morris <rgm@gnu.org>
12972 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
12973 Not clear what it was for, and it causes various bugs. (Bug#9839)
12975 2011-10-28 Eli Zaretskii <eliz@gnu.org>
12977 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
12978 possible random value that matches one of those tested as
12979 condition to clear the mouse face.
12981 2011-10-28 Chong Yidong <cyd@gnu.org>
12983 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
12985 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
12987 * window.c (make_window): Initialize phys_cursor_on_p.
12989 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
12991 * lisp.h (struct Lisp_Symbol): Update comments.
12993 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
12995 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
12997 2011-10-28 Eli Zaretskii <eliz@gnu.org>
12999 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
13000 <oslsachem@gmail.com> for helping to debug this.
13002 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
13003 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
13004 (g_b_init_get_glyph_outline_w): New static variables.
13005 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
13006 (GetGlyphOutlineW_Proc): New typedefs.
13007 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
13008 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
13010 (w32font_open_internal, compute_metrics):
13011 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
13012 instead of calling the "wide" APIs directly.
13014 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
13016 * w32.h (syms_of_w32font): Add prototype.
13018 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13020 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
13021 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
13022 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
13023 (Fmove_to_window_line): Doc fix.
13025 2011-10-27 Chong Yidong <cyd@gnu.org>
13027 * process.c (make_process): Set gnutls_state to NULL.
13029 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
13030 non-NULL, regardless of GNUTLS_INITSTAGE.
13031 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
13032 an error. Set process slots as soon as we allocate them.
13034 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
13036 2011-10-27 Chong Yidong <cyd@gnu.org>
13038 * gnutls.c (emacs_gnutls_deinit): New function.
13039 Deallocate credentials structures as well as calling gnutls_deinit.
13040 (Fgnutls_deinit, Fgnutls_boot): Use it.
13042 * process.c (make_process): Initialize GnuTLS credentials to NULL.
13043 (deactivate_process): Call emacs_gnutls_deinit.
13045 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13047 * image.c (x_create_x_image_and_pixmap):
13048 * w32.c (sys_rename, w32_delayed_load):
13049 * w32font.c (fill_in_logfont):
13050 * w32reg.c (x_get_string_resource): Silence compiler warnings.
13052 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
13054 * w32fns.c (w32_default_color_map): New function,
13055 extracted from Fw32_default_color_map.
13056 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
13058 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
13060 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
13062 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
13064 * keyboard.c (test_undefined): New function (bug#9751).
13065 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
13067 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
13069 * sysdep.c (init_sys_modes): Fix the check for the controlling
13070 terminal (Bug#6649).
13072 2011-10-20 Eli Zaretskii <eliz@gnu.org>
13074 * dispextern.h (struct bidi_it): New member next_en_type.
13076 * bidi.c (bidi_line_init): Initialize the next_en_type member.
13077 (bidi_resolve_explicit_1): When next_en_pos is valid for the
13078 current character, check also for next_en_type being WEAK_EN.
13079 (bidi_resolve_weak): Don't enter the expensive loop if the current
13080 position is before next_en_pos. Record the bidi type of the first
13081 non-ET, non-BN character we find, in addition to its position.
13082 (bidi_level_of_next_char): Invalidate next_en_type when
13083 next_en_pos is over-stepped.
13085 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
13087 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13088 * editfns.c: Rewrite current-time-zone so that it invokes
13089 the equivalent of (format-time-string "%Z") to get the time zone name.
13090 This fixes a bug when the time zone name contains characters that
13091 need converting from the system time locale to Emacs internal format.
13092 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13093 that patch fixed format-time-string to do the conversion, but
13094 I forgot to fix current-time-zone.
13095 (format_time_string): New function, containing most of
13096 what Fformat_time_string used to contain.
13097 (Fformat_time_string): Rewrite in terms of format_time_string.
13098 This doesn't change this function's behavior.
13099 (current-time-zone): Rewrite to use format_time_string.
13100 This fixes the bug reported by Michael Schierl in
13101 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13102 Jason Rumney's 2007-06-07 change worked around this bug, but
13104 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13106 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13108 * xdisp.c (start_display): If the character at POS is displayed
13109 via a display vector, reset IT->current.dpvec_index to zero.
13110 (try_window_reusing_current_matrix): If a line ends in a display
13111 vector or the next line starts in a display vector, continue
13112 redrawing the window even though the character position of
13113 start_row was reached.
13116 2011-10-18 Chong Yidong <cyd@gnu.org>
13118 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13119 with nobreak-char-display too.
13121 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13123 Fix part 3 of bug#9771.
13124 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13125 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13126 non-neutral characters if the current character is a paragraph
13127 separator (a.k.a. Newline). This avoids running the same
13128 expensive loop twice, once when we consume the preceding newline
13129 and the other time when the line actually needs to be displayed.
13130 Avoid the loop when we see neutrals on the base embedding level
13131 following a character whose directionality is the same as the
13132 paragraph's. This avoids running the expensive loop when a line
13133 ends in a long sequence of neutrals, like control characters.
13134 Add assertion against STRONG_AL type. Slightly rearrange code
13135 that determines the type of a neutral given the first non-neutral
13137 (bidi_level_of_next_char): Set next_en_pos to zero when
13138 invalidating its info.
13140 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13142 * xdisp.c (push_display_prop): Determine whether to record string
13143 or buffer position by IT->string, not by IT->method. Allow
13144 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13145 (move_it_vertically_backward): Don't look for character position
13146 immediately after the newline when in a continuation line.
13149 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13151 * window.c (coordinates_in_window): Rewrite and delabelize
13152 vertical border check. (Bug#5357) (Bug#9618)
13154 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13156 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13157 errors in XSetWindowBorder (bug#9310).
13159 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13161 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13162 avoid crash when xmalloc overrun checking is enabled.
13164 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13166 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13167 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13168 cursor motion with <left> and <right> arrow keys.
13170 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13171 some callers set that themselves.
13173 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13175 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13176 display string and the previous row comes from the same string and
13177 is empty. (Bug#9739) (Bug#9738)
13179 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13181 * doc.c (get_doc_string): Encode file name (bug#9735).
13183 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13185 * bidi.c (bidi_level_of_next_char):
13186 * xdisp.c (get_visually_first_element): Remove old incorrect
13187 comments regarding the Unicode Line Separator character.
13189 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13191 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13193 * alloc.c (Fgc_status): Do not access beyond zombies array
13194 boundary if nzombies > MAX_ZOMBIES.
13195 * alloc.c (dump_zombies): Add missing format specifier.
13197 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13199 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13200 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13202 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13203 Some packages use them to denote characters with modifiers.
13205 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13207 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13208 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13209 matching a pp-number. Rename parameter var to var1.
13211 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13213 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13215 2011-10-08 Glenn Morris <rgm@gnu.org>
13217 * callint.c (Fcall_interactively): Give a more explicit error for the
13218 'c' case with a non-character input. (Bug#8479)
13220 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13222 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13224 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13225 lines that are hscrolled on the left.
13227 * dispnew.c (buffer_posn_from_coords): Account for a possible
13228 presence of header-line. (Bug#4426)
13230 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13232 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13233 Don't advertise functionality which we discourage or doesn't work.
13235 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13237 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13238 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13239 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13240 this makes Emacs dump core during garbage collection on rare
13241 occasions. sizeof is obviously inferior to offsetof here, so
13242 stick with offsetof.
13243 (GC_POINTER_ALIGNMENT): New macro.
13244 (mark_memory): Omit 3rd (offset) arg; caller changed.
13245 Don't assume EMACS_INT alignment is the same as pointer alignment.
13247 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13249 * keyboard.c (read_key_sequence_remapped): New var.
13250 (read_key_sequence): Compute remapping in the right buffer.
13251 (command_loop_1): Use read_key_sequence's remapping directly.
13253 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13255 * dired.c (file_name_completion): Don't expand file name.
13256 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13257 before checking file name handler.
13259 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13260 they've been requested explicitly (bug#9591).
13262 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13264 * keymap.c (Fsingle_key_description): Use make_specified_string
13265 instead of build_string to build string from push_key_description.
13268 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13270 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13271 This fixes a Y2038 bug on 64-bit hosts.
13272 * buffer.c (reset_buffer):
13273 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13274 (Fclear_buffer_auto_save_failure):
13275 Use 0, not -1, to represent an unset failure time, since time_t
13276 might not be signed.
13278 Remove dependency on glibc malloc internals.
13279 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13280 Move back here from lisp.h, but with their new implementations.
13281 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13282 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13283 * charset.c (charset_table_init): New static var.
13284 (syms_of_charset): Use it instead of xmalloc. This removes a
13285 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13286 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13287 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13288 Move back to alloc.c.
13289 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13290 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13292 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13294 * nsterm.m (windowDidResize): Call x_set_window_size only when
13295 ns_in_resize is true. Otherwise set pixelwidth/height and
13296 call change_frame_size (Bug#9628).
13298 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13300 Port --enable-checking=all to Fedora 14 x86-64.
13301 * charset.c (syms_of_charset): Also account for glibc malloc's
13302 internal overhead when calculating the initial malloc maximum.
13304 Port --enable-checking=all to Fedora 14 x86.
13305 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13307 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13308 (overrun_check_realloc, overrun_check_free):
13309 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13310 That way, xmalloc returns a properly-aligned pointer even if
13311 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13312 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13313 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13314 into account when calculating the initial malloc maximum.
13315 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13316 Move here from alloc.c, so that charset.c can use it too.
13317 Properly align; the old code wasn't right for common 32-bit hosts
13318 when configured with --enable-checking=all.
13319 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13320 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13322 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13324 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13327 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13329 * xdisp.c (compute_display_string_end): If there's no display
13330 string at CHARPOS, return -1.
13332 * bidi.c (bidi_fetch_char): When compute_display_string_end
13333 returns a negative value, treat the character as a normal
13334 character not covered by a display string. (Bug#9624)
13336 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13338 * lread.c (Fread_from_string): Fix typo in docstring.
13340 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13342 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13343 newline, reseat the iterator instead of bidi-iterating there one
13344 character at a time. (Bug#9610)
13345 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13346 TO_CHARPOS if the bidi iterator is at base embedding level.
13348 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13350 * lread.c (readevalloop): Use correct code for NBSP.
13351 (read1): Likewise. (Bug#9608)
13353 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13355 * dbusbind.c (Fdbus_register_signal): When service is not
13356 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13358 2011-09-25 Glenn Morris <rgm@gnu.org>
13360 * buffer.c (truncate-lines): Doc fix.
13362 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
13364 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
13365 (Fset_window_next_buffers): Doc fix.
13367 2011-09-24 Glenn Morris <rgm@gnu.org>
13369 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
13371 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
13373 Fix minor problems found by static checking.
13374 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
13375 * indent.c (Fvertical_motion): Fix == vs = typo.
13377 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13379 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13380 Default value is now t. Doc fix.
13382 * indent.c (Fvertical_motion): Compute and apply the overshoot
13383 logic when moving up, not only when moving down. Fix the
13384 confusing name and values of the it_overshoot_expected variable;
13385 logic changes accordingly. (Bug#9254) (Bug#9549)
13387 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13388 CHARPOS is covered by a display string which includes newlines.
13389 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13390 is covered by a display string with embedded newlines.
13392 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13394 * dbusbind.c (Fdbus_register_signal): Add match rule to
13395 Vdbus_registered_objects_table. (Bug#9581)
13396 (Fdbus_register_method, Vdbus_registered_objects_table):
13399 2011-09-24 Jim Meyering <meyering@redhat.com>
13401 do not ignore write error for any output size
13402 The previous change was incomplete.
13403 While it makes emacs --batch detect the vast majority of stdout
13404 write failures, errors were still ignored whenever the output size is
13405 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13406 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13407 && echo FAIL: ignored write error
13408 FAIL: ignored write error
13409 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13410 && echo FAIL: ignored write error
13411 FAIL: ignored write error
13412 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13414 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13416 * emacs.c (Fkill_emacs): In noninteractive mode exit
13417 non-successfully if a write error occurred on stdout. (Bug#9574)
13419 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13421 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13424 * dispextern.h (struct it): Update the comment documenting what
13427 2011-09-20 Eli Zaretskii <eliz@gnu.org>
13429 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
13430 a display string, extend search for cursor position to end of row.
13431 (find_row_edges): If the row ends in a newline from a display
13432 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
13433 Handle the case of a display string with multiple newlines.
13434 (Fcurrent_bidi_paragraph_direction): Fix search for previous
13435 non-empty line. Fixes confusing cursor motion with arrow keys at
13436 the beginning of a line that starts with whitespace.
13438 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13440 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
13443 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
13445 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
13446 boolean (Bug#9154).
13448 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13450 * xdisp.c (display_line): Record maximum and minimum buffer
13451 positions even if no glyphs were produced (e.g., by a zero-width
13452 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
13453 buffer positions that will be removed from the glyph row because
13455 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
13456 column is beyond frame width: don't subtract 1 "pixel" when
13457 computing width of the stretch.
13458 (reseat_at_next_visible_line_start): Undo the change made on
13459 2011-09-17 that saved paragraph information and restored it after
13460 the call to `reseat'. (Bug#9545)
13462 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13464 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
13465 and turn window cursor on if cleared (Bug#9415).
13467 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
13469 * search.c (boyer_moore): Take unibyte characters from pattern
13470 literally. (Bug#9458)
13472 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13474 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
13476 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
13478 Fix minor problem found by static checking.

13480 initialized, to pacify gcc -Wuninitialized.
13482 * fileio.c: Report proper errno when syscall falls.
13483 (Finsert_file_contents): Save and restore errno,
13484 so that report_file_error outputs the correct diagnostic.
13485 (Fwrite_region) [CLASH_DETECTION]: Likewise.
13487 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13489 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
13491 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13493 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
13494 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
13496 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13498 * xdisp.c (reseat_at_next_visible_line_start): Keep information
13499 about the current paragraph and restore it after the call to reseat.
13501 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
13502 (bidi_find_paragraph_start): Search back for paragraph beginning
13503 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
13504 (bidi_move_to_visually_next): Only trigger paragraph-related
13505 computations when the last character is a newline or at EOB, not
13506 just any NEUTRAL_B. (Bug#9470)
13508 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
13509 truncated lines if point is covered by a display string. (Bug#9524)
13511 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13513 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13514 (cons_to_x_long): New function.
13515 (lisp_data_to_selection_data): Use it. Correct the test for
13516 short-versus-long data; it was negated. Break out of vector
13517 loop, for efficiency, when a long datum is discovered.
13519 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13521 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
13523 2011-09-16 Eli Zaretskii <eliz@gnu.org>
13525 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
13526 GCC PR/17406) by declaring this function with external scope.
13528 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13530 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
13531 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
13533 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
13535 * editfns.c (Fformat): Correctly handle text properties on "%%".
13537 2011-09-15 Eli Zaretskii <eliz@gnu.org>
13539 * xterm.c (x_draw_composite_glyph_string_foreground):
13540 * w32term.c (x_draw_composite_glyph_string_foreground):
13541 * term.c (encode_terminal_code):
13542 * composite.c (composition_update_it, get_composition_id):
13543 * xdisp.c (get_next_display_element)
13544 (fill_composite_glyph_string): Add comments about special meaning
13545 of TAB characters in a composition.
13547 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13549 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13550 This occurs when processing a multibyte format.
13551 Problem reported by Wolfgang Jenker.
13553 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13555 * xdisp.c (try_cursor_movement): Only check for exact match if
13556 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13558 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13560 Remove unused external symbols.
13561 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13562 * xdisp.c (calc_pixel_width_or_height): Now static.
13563 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
13564 * indent.c (check_display_width):
13565 * w32term.c: Fix comment to match code.
13566 * xterm.c, xterm.h (x_catching_errors): Remove.
13568 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13570 * xselect.c: Use signed conversions more consistently (Bug#9498).
13571 (selection_data_to_lisp_data): Assume incoming selection data are
13572 signed integers, not unsigned. This is to be consistent with
13573 outgoing selection data, which was modified to use signed integers
13574 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13575 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13576 expects long, not unsigned long.
13578 2011-09-14 Eli Zaretskii <eliz@gnu.org>
13580 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
13581 computation of loop end. Reported by Johan Bockgård
13584 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13586 * frame.c (Fother_visible_frames_p): Function deleted.
13588 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13590 * indent.c (compute_motion): Process display vector front to back
13591 rather than the other way around. (Bug#2496)
13593 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13595 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13597 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13599 * minibuf.c (Fread_from_minibuffer): Doc fix.
13601 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13603 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13604 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13606 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13608 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13609 value for non-existent files.
13611 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13613 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13614 set its "size" to -1. This will set the modtime_size field of
13615 the corresponding buffer to -1, which is what
13616 verify-visited-file-modtime expects for files that do not exist.
13619 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13621 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13623 * lisp.h: ... from here. push_key_description is no longer
13624 defined in keyboard.c, so its declaration should not be in
13625 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13626 logically belongs with push_key_description.
13628 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
13630 * buffer.h: Include <sys/types.h> instead of <time.h>.
13631 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
13632 Problem reported by Herbert J. Skuhra.
13634 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
13636 * xml.c (parse_region): Make the parsing work for
13637 non-comment-starting XML files again (bug#9144).
13639 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
13641 * image.c (gif_load): Fix calculation of bottom and right corner.
13644 2011-09-10 Eli Zaretskii <eliz@gnu.org>
13646 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
13647 redisplay in small windows.
13649 2011-09-09 Eli Zaretskii <eliz@gnu.org>
13651 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
13653 2011-09-08 Martin Rudalics <rudalics@gmx.at>
13655 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
13656 Operate on live windows only.
13658 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
13660 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
13662 2011-09-07 Eli Zaretskii <eliz@gnu.org>
13664 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
13665 only under bidi iteration.
13667 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
13669 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
13671 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13673 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13674 Without this fix, the command to link temacs failed due to an
13675 undefined symbol __builtin_isnan. This is because
13676 /usr/include/iso/math_c99.h #defines isnan(x) to
13677 __builtin_isnan(x), but the bundled gcc, which identifies itself
13678 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
13680 * floatfns.c (isnan): #undef, and then #define to a clone of
13682 (Fisnan): Always define, since it's always available now.
13683 (syms_of_floatfns): Always define isnan at the Lisp level.
13685 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13687 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13689 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13691 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13692 The previous code assumed that file offsets (off_t values) fit in
13693 EMACS_INT variables, which is not true on typical 32-bit hosts.
13694 The code messed up by falsely reporting buffer overflow in cases
13695 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13696 when "big" contains more than 2**29 bytes, even though this
13697 inserts just one byte and does not overflow the buffer.
13698 (Finsert_file_contents): Store file offsets as off_t
13699 values, not as EMACS_INT values. Check for overflow when
13700 converting between EMACS_INT and off_t. When checking for
13701 buffer overflow or for overlap, take the offsets into account.
13702 Don't use EMACS_INT for small values where int suffices.
13703 When checking for overlap, fix a typo: ZV was used where
13704 ZV_BYTE was intended.
13705 (Fwrite_region): Don't assume off_t fits into 'long'.
13706 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13708 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13710 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13712 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13714 sprintf-related integer and memory overflow issues (Bug#9412).
13716 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13717 (esprintf, exprintf, evxprintf): New functions.
13718 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
13719 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
13720 (modify_event_symbol): Do not assume that the length of
13721 name_alist_or_stem is safe to alloca and fits in int.
13722 (Fexecute_extended_command): Likewise for function name and binding.
13723 (Frecursion_depth): Wrap around reliably on integer overflow.
13724 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
13725 since some callers pass EMACS_INT values.
13726 (Fsingle_key_description): Don't crash if symbol name contains more
13727 than MAX_ALLOCA bytes.
13728 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
13729 (get_minibuffer): Arg is now EMACS_INT, not int.
13730 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
13731 (esprintf, exprintf, evxprintf): New decls.
13732 * window.h (command_loop_level, minibuf_level): Reflect API changes.
13734 * dbusbind.c (signature_cat): New function.
13735 (xd_signature, Fdbus_register_signal):
13736 Do not overrun buffer; instead, report string overflow.
13738 * dispnew.c (add_window_display_history): Don't overrun buffer.
13739 Truncate instead; this is OK since it's just a log.
13741 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
13742 even if the time zone offset is outlandishly large.
13743 Don't mishandle offset == INT_MIN.
13745 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
13746 when creating daemon; the previous buffer-overflow check was incorrect.
13748 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
13749 which has the guts of the old verror function.
13751 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
13752 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
13754 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
13755 (font_unparse_xlfd): Don't blindly alloca long strings.
13756 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
13757 fits in int, when using sprintf. Use single snprintf to count
13758 length of string rather than counting it via multiple sprintfs;
13759 that's simpler and more reliable.
13760 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
13761 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
13762 sprintf, in case result does not fit in int.
13764 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
13765 (fontset_from_font): Print it.
13767 * frame.c (tty_frame_count): Now printmax_t, not int.
13768 (make_terminal_frame, set_term_frame_name): Print it.
13769 (x_report_frame_params): In X, window IDs are unsigned long,
13770 not signed long, so print them as unsigned.
13771 (validate_x_resource_name): Check for implausibly long names,
13772 and don't assume name length fits in 'int'.
13773 (x_get_resource_string): Don't blindly alloca invocation name;
13774 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
13777 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
13778 (xg_check_special_colors, xg_set_geometry):
13779 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
13781 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
13782 Use esprintf, not sprintf, in case result does not fit in int.
13784 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13785 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
13786 it as a large positive number.
13787 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
13788 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13790 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
13791 in case result does not fit in int.
13793 * print.c (float_to_string): Detect width overflow more reliably.
13794 (print_object): Make sprintf buffer a bit bigger, to avoid potential
13795 buffer overrun. Don't assume list length fits in 'int'. Treat
13796 print length of 0 as 0, not as infinity; to be consistent with other
13797 uses of print length in this function. Don't overflow print length
13798 index. Don't assume hash table size fits in 'long', or that
13799 vectorlike size fits in 'unsigned long'.
13801 * process.c (make_process): Use printmax_t, not int, to format
13802 process-name gensyms.
13804 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
13806 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
13807 to avoid potential buffer overrun.
13809 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
13810 if X resource line is longer than 512 bytes.
13812 * xfns.c (x_window): Make sprintf buffer a bit bigger
13813 to avoid potential buffer overrun.
13815 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
13817 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
13819 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13821 Integer overflow fixes for scrolling, etc.
13822 Without these, Emacs silently mishandles large integers sometimes.
13823 For example, "C-u 4294967297 M-x recenter" was treated as if
13824 it were "C-u 1 M-x recenter" on a typical 64-bit host.
13826 * xdisp.c (try_window_id): Check Emacs fixnum range before
13827 converting to 'int'.
13829 * window.c (window_scroll_line_based, Frecenter):
13830 Check that an Emacs fixnum is in range before assigning it to 'int'.
13831 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
13832 values converted from Emacs fixnums.
13833 (Frecenter): Don't wrap around a line count if it is out of 'int'
13834 range; instead, treat it as an extreme value.
13835 (Fset_window_configuration, compare_window_configurations):
13836 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
13838 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
13839 that can exceed INT_MAX. Check that EMACS_INT value is in range
13840 before assigning it to the (possibly-narrower) index.
13841 (match_limit): Don't assume that a fixnum can fit in 'int'.
13843 * print.c (print_object): Use ptrdiff_t, not int, for index that can
13846 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
13847 (Fvertical_motion): Don't wrap around LINES values that don't fit
13848 in 'int'. Instead, treat them as extreme values. This is good
13849 enough for windows, which can't have more than INT_MAX lines anyway.
13851 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13853 * Require libxml/parser.h to avoid compilation warning.
13855 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
13857 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
13858 since this reportedly can destroy thread storage.
13860 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
13862 * syntax.c (find_defun_start): Update all cache variables if
13863 exiting early (Bug#9401).
13865 2011-08-30 Eli Zaretskii <eliz@gnu.org>
13867 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
13869 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
13870 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
13871 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
13873 * term.c (tty_append_glyph): New function.
13874 (produce_stretch_glyph): Static function and its prototype deleted.
13876 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
13879 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
13881 * image.c (parse_image_spec): Check for nonnegative, not for positive,
13882 when checking :margin (Bug#9390).
13883 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
13884 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
13885 so that the name doesn't mislead. All uses changed.
13887 2011-08-28 Johan Bockgård <bojohan@gnu.org>
13889 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
13892 2011-08-27 Eli Zaretskii <eliz@gnu.org>
13894 * xdisp.c (move_it_to): Don't bail out early when reaching
13895 position beyond to_charpos, if we are scanning backwards.
13896 (move_it_vertically_backward): When DY == 0, make sure we get to
13897 the first character in the line after the newline.
13899 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
13901 * ccl.c: Improve and simplify overflow checking (Bug#9196).
13902 (ccl_driver): Do not generate an out-of-range pointer.
13903 (Fccl_execute_on_string): Remove unnecessary check for
13904 integer overflow, noted by Stefan Monnier in
13905 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
13906 Remove a FIXME that didn't need fixing.
13907 Simplify the newly-introduced buffer reallocation code.
13909 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
13911 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
13913 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
13915 Integer and memory overflow issues (Bug#9196).
13917 * doc.c (get_doc_string): Rework so that
13918 get_doc_string_buffer_size is the actual buffer size, rather than
13919 being 1 less than the actual buffer size; this makes xpalloc more
13922 * image.c (x_allocate_bitmap_record, cache_image):
13923 * xselect.c (Fx_register_dnd_atom):
13924 Simplify previous changes by using xpalloc.
13926 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
13927 since either will do and ptrdiff_t is convenient with xpalloc.
13929 * charset.c (charset_table_size)
13930 (struct charset_sort_data.priority): Now ptrdiff_t.
13931 (charset_compare): Don't overflow if priorities differ greatly.
13932 (Fsort_charsets): Don't assume list length fits in int.
13933 Check for size-calculation overflow when allocating sort data.
13934 (syms_of_charset): Allocate an initial charset table that is
13935 just under 64 KiB, to avoid problems with glibc malloc and mmap.
13937 * cmds.c (internal_self_insert): Check for size-calculation overflow.
13939 * composite.h (struct composition.glyph_len): Now int, not unsigned.
13940 The actual value is always <= INT_MAX, and leaving it unsigned made
13941 overflow checking harder.
13943 * dispextern.h (struct glyph_matrix.rows_allocated)
13944 (struct face_cache.size): Now ptrdiff_t, for convenience in use
13945 with xpalloc. The values are still always <= INT_MAX.
13947 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
13949 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
13950 (SAFE_NALLOCA): New macro.
13952 * region-cache.c (struct boundary.pos, find_cache_boundary)
13953 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
13954 (set_cache_region, invalidate_region_cache)
13955 (revalidate_region_cache, know_region_cache, region_cache_forward)
13956 (region_cache_backward, pp_cache):
13957 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
13958 so that ptrdiff_t * can be passed to xpalloc.
13959 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
13960 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
13961 (pp_cache): Don't assume cache_len fits in int.
13962 * region-cache.h: Adjust extern decls to match.
13964 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
13965 EMACS_INT, since either will do, for xpalloc.
13967 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
13968 (xnmalloc, xnrealloc, xpalloc): New functions.
13970 * bidi.c (bidi_shelve_header_size): New constant.
13971 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
13972 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
13974 * bidi.c (bidi_cache_shrink):
13975 * buffer.c (overlays_at, overlays_in, record_overlay_string)
13977 Don't update size of array until after memory allocation succeeds,
13978 because xmalloc/xrealloc may not return.
13979 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
13980 now that we have proper integer overflow checking.
13981 (record_overlay_string, overlay_strings): Catch overflows when
13982 calculating size of overlay_str_buf.
13984 * callproc.c (Fcall_process): Check for size overflow when
13985 calculating size of args2.
13986 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
13987 Normally we prefer signed values, but sticking with ptrdiff_t would
13988 require adding more-complicated checks.
13990 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
13991 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
13992 Redo buffer-overflow calculations to avoid integer overflow.
13993 Add a FIXME comment where memory seems to be over-allocated.
13995 * character.c (Fstring): Check for size-calculation overflow.
13997 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
13998 unnecessary integer overflow. Check for size overflow.
13999 (encode_coding_object): Don't update size until xmalloc succeeds.
14001 * composite.c (get_composition_id): Check for overflow in glyph
14002 length calculations.
14004 Integer and memory overflow fixes for display code.
14005 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
14006 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
14007 (scrolling_window): Check for overflow in size calculations.

14019 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
14020 (get_doc_string): Check for size calculation overflow.
14021 Don't update size until allocation succeeds.
14022 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
14023 EMACS_INT, where ptrdiff_t will do.
14024 (Fsubstitute_command_keys): Check for string overflow.
14026 * editfns.c (set_time_zone_rule): Don't assume environment length
14028 (message_length): Now ptrdiff_t, not int.
14029 (Fmessage_box): Don't update size until allocation succeeds.
14030 Don't assume message length fits in int.
14031 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
14033 * emacs.c (main): Do not reallocate argv, since there is a null at
14034 the end that can be overwritten, and this way there's no need to
14035 worry about size-calculation overflow.
14036 (sort_args): Check for size-calculation overflow.
14038 * eval.c (init_eval_once, grow_specpdl): Don't update size until
14040 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
14042 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
14043 (x_set_scroll_bar_width, x_figure_window_size):
14044 Check for integer overflow.
14045 (x_set_alpha): Do not assume XINT fits in int.
14047 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
14048 This is for the members text_lines, text_cols, total_lines, total_cols,
14049 where the system imposes an 'int' limit.
14051 * fringe.c (Fdefine_fringe_bitmap):
14052 Don't update size until alloc works.
14054 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
14055 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
14057 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
14058 Check for size-calculation overflow.
14059 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
14060 do, as we prefer signed integers.
14061 (id_to_widget.max_size, id_to_widget.used)
14062 (xg_store_widget_in_map, xg_remove_widget_from_map)
14063 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
14064 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
14065 Use and return ptrdiff_t, not int.
14066 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
14067 * gtkutil.h: Change prototypes to match the above.
14069 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
14070 are duplicate now that they've been promoted to lisp.h.
14071 (x_allocate_bitmap_record, x_alloc_image_color)
14072 (make_image_cache, cache_image, xpm_load):
14073 Don't update size until alloc is done.

14084 Use ptrdiff_t, not int, to count maps.
14085 (read_char_minibuf_menu_prompt): Check for overflow in size
14086 calculations. Don't update size until allocation succeeds.
14087 Redo calculations to avoid overflow.
14088 * keyboard.h: Change prototypes to match the above.
14090 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,

14116 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
14117 for command line length. Do not attempt to address one before the
14118 beginning of an array, as that's not portable.
14120 * term.c (max_frame_lines): Remove; unused.
14121 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
14123 (encode_terminal_code, calculate_costs): Check for size

14130 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
14131 subtracting pointers.

14147 (Finternal_make_lisp_face, cache_face):
14148 Check for size calculation overflow.
14149 (cache_face): Treat size calculation overflows as if they were

14153 (Fx_change_window_property): Use ptrdiff_t, not int, to count
14154 sizes, since they can exceed INT_MAX in size. Check for size

14158 (xg_select): Check for size calculation overflow.
14159 Don't update size until alloc done.
14161 * xrdb.c (get_environ_db): Don't assume path length fits in int,
14162 as sprintf is limited to int lengths.
14164 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
14165 (X_LONG_MIN): New macros.
14166 Use them to make the following changes clearer.
14167 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
14168 This change doesn't affect the value now, but it may help remind
14169 future maintainers not to raise the value too much later.
14170 (SELECTION_QUANTUM): Remove, replacing with ...
14171 (selection_quantum): ... new function, which avoids overflow.
14173 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
14174 assumption that selection length fits in 'int'.

14187 (lisp_data_to_selection_data, x_property_data_to_lisp):

14191 Don't store size until memory allocation succeeds.
14192 (x_get_window_property): Plug memory leak on memory exhaustion.
14193 Don't double-block input; malloc is safe here. Don't assume 2**34
14194 - 4 fits in unsigned long. Add an xassert to check
14195 XGetWindowProperty overflow. Be more careful about overflow
14196 calculations, and distinguish size from memory overflow better.
14197 (receive_incremental_selection): When tracing, don't assume
14198 unsigned int is less than INT_MAX.
14199 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
14200 harmful) conversions of unsigned short to int.
14201 (lisp_data_to_selection_data): Don't assume that integers
14202 in the range -65535 through -1 fit in an X unsigned short.
14203 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14204 result parameters unless successful. Rely on cons_to_unsigned
14205 to report problems with elements; the old code wasn't right anyway.
14206 (x_check_property_data): Check for int overflow; we cannot use
14207 a wider type due to X limits.
14208 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

14240 * lisp.h (hash_lookup, hash_put):
14241 * minibuf.c (Ftest_completion):
14242 Use ptrdiff_t for hash table indexes, not int (which is too
14243 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
14244 32-bit --with-wide-int hosts).
14246 * charset.c (Fdefine_charset_internal): Check for integer overflow.
14247 Add a FIXME comment about memory leaks.
14248 (syms_of_charset): Don't assume xmalloc returns.
14250 Don't assume that stated character widths fit in int.

14254 Use sanitize_char_width to avoid undefined and/or bad behavior
14255 with outlandish widths.
14256 * character.h (sanitize_tab_width): Rename from sanitize_width,
14257 now that we have two such functions. All uses changed.
14258 (sanitize_char_width): New inline function.
14260 Don't assume that tab-width fits in int.

14278 exceed limits imposed by XClientMessageEvent, as well as the usual
14279 ptrdiff_t and size_t limits.
14281 * keyboard.c: Overflow, signedness and related fixes.
14282 (make_lispy_movement): Use same integer type in forward decl
14283 that is used in the definition.
14284 (read_key_sequence, keyremap_step):
14285 Change bufsize argument back to int, undoing my 2011-03-30 change.
14286 We prefer signed types, and int is wide enough here.
14287 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14288 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14289 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14290 length, not size_t. Use ptrdiff_t for index, not int.
14291 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
14292 possibility of integer overflow.
14294 Overflow, signedness and related fixes for images.
14296 * dispextern.h (struct it.stack[0].u.image.image_id)
14297 (struct_it.image_id, struct image.id, struct image_cache.size)
14298 (struct image_cache.used, struct image_cache.ref_count):
14299 * gtkutil.c (update_frame_tool_bar):
14300 * image.c (x_reference_bitmap, Fimage_size, Fimage_mask_p)

14303 * nsmenu.m (update_frame_tool_bar):
14304 * xdisp.c (calc_pixel_width_or_height):
14305 * xfns.c (image_cache_refcount):
14306 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
14307 on typical 64-bit hosts.
14309 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
14310 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

14313 when the callers expect that.
14314 (image_ascent): Redo ascent calculation to avoid int overflow.
14315 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
14316 (lookup_image): Remove unnecessary tests.
14317 (xbm_image_p): Locals are now of int, not EMACS_INT,
14318 since parse_image_check makes sure they fit into int.
14319 (png_load, gif_load, svg_load_image):
14320 Prefer int to unsigned where either will do.
14321 (tiff_handler): New function, combining the cores of the
14322 old tiff_error_handler and tiff_warning_handler.
14323 This function is rewritten to use vsnprintf and thereby avoid
14324 stack buffer overflows. It uses only the features of vsnprintf
14325 that are common to both POSIX and native Microsoft.
14326 (tiff_error_handler, tiff_warning_handler): Use it.
14327 (tiff_load, gif_load, imagemagick_load_image):
14328 Don't assume :index value fits in 'int'.
14329 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
14330 (imagemagick_load_image): Check that crop parameters fit into
14331 the integer types that MagickCropImage accepts. Don't assume
14332 Vimagemagick_render_type has a nonnegative value. Don't assume
14333 size_t fits in 'long'.
14334 (gs_load): Use printmax_t to print the widest integers possible.
14335 Check for integer overflow when computing image height and width.
14337 2011-08-26 Eli Zaretskii <eliz@gnu.org>
14339 * xdisp.c (redisplay_window): Don't force window start if point

14347 handle_single_display_spec, not just 1 or zero.
14348 (handle_single_display_spec): If the display spec is of the form
14349 `(space ...)', and specifies display in the text area, return 2
14351 (try_cursor_movement): Check for the need to scroll more
14352 accurately, and prefer exact match for point under bidi.
14353 Don't advance `row' beyond the last row of the window.
14355 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
14356 into disp_prop; all users changed.
14358 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
14359 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
14360 for the text covered by the display property.

14370 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
14371 buffers, return left-to-right.
14372 (set_cursor_from_row): Consider candidate row a win if its glyph
14373 represents a newline and point is on that newline. Fixes cursor
14374 positioning on the newline at EOL of R2L text within L2R
14375 paragraph, and vice versa.
14376 (try_cursor_movement): Check continued rows, in addition to
14377 continuation rows. Fixes unwarranted scroll when point enters a
14378 continued line of R2L text within an L2R paragraph, or vice versa.
14379 (cursor_row_p): Consider the case of point being equal to
14380 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
14381 from the end of a short line to the beginning of a continued line
14382 of R2L text within L2R paragraph.
14383 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
14384 composed characters.
14386 * bidi.c (bidi_check_type): Use xassert.
14387 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
14390 2011-08-23 Eli Zaretskii <eliz@gnu.org>

14397 * nsfont.m (ns_otf_to_script): Fix typo.
14399 2011-08-22 Kenichi Handa <handa@m17n.org>
14401 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
14402 extra slot even if the purpose is char-code-property-table.
14404 2011-08-23 Eli Zaretskii <eliz@gnu.org>
14406 * xdisp.c (redisplay_window): When computing centering_position,
14407 account for the height of the header line. (Bug#8874)
14409 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14410 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14411 candidate is selected by the mouse, and that candidate has a
14412 composed character under the mouse.
14414 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14415 coordinates reported by pos-visible-in-window-p for a composed
14416 character in column zero.
14418 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
14420 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
14422 2011-08-22 Eli Zaretskii <eliz@gnu.org>
14424 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
14425 consider it a hit if to_charpos is anywhere in the range of the
14426 composed buffer positions.
14428 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
14430 * image.c (gif_load): Don't assume that each subimage has the same
14431 dimensions as the base image. Handle disposal method that is
14432 "undefined" by the gif spec (Bug#9335).
14434 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
14436 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
14437 (Fcondition_case): Document `debug' symbol in error handler.
14439 2011-08-19 Eli Zaretskii <eliz@gnu.org>
14441 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
14442 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
14443 from an Org mode buffer to a Speedbar frame.
14445 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
14446 a composition, take its buffer position from IT->cmp_it.charpos.
14447 Fixes cursor positioning at the beginning of a line that begins
14448 with a composed character.
14450 2011-08-18 Eli Zaretskii <eliz@gnu.org>
14452 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
14453 character bidirectional type, use STRONG_L instead. Fixes crashes
14454 in a buffer produced by `describe-categories'.
14456 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
14457 members before the level stack, so they would be saved and
14458 restored when copying iterator state. Fixes incorrect reordering
14459 around TABs covered by display properties.
14461 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
14463 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

14469 Remove unnecessary aborts (Bug#9081).
14471 2011-08-17 Eli Zaretskii <eliz@gnu.org>
14473 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
14474 has no `load' handler, try opening the file locally. (Bug#9311)
14476 2011-08-16 Ken Brown <kbrown@cornell.edu>
14478 * gmalloc.c: Expand comment.
14480 2011-08-16 Eli Zaretskii <eliz@gnu.org>
14482 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate

14533 * xdisp.c (move_it_in_display_line_to): Don't invoke
14534 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
14535 ppos_it. Fixes vertical cursor motion when line beginning is
14536 covered by an image. (Bug#9296)
14538 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
14540 * nsterm.h (ns_run_ascript): Declare.

14544 (ns_run_ascript): New function.
14545 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
14546 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
14547 the event loop. Get status from as_status (Bug#7276).
14549 * nsterm.m (sendEvent): If event is NSApplicationDefined and
14550 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
14551 the event loop (Bug#7276).
14553 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

14577 (Fnetwork_interface_list): Allocate in increments of bytes instead
14578 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
14579 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
14581 (struct ifflag_def): notrailers is smart on OSX.
14582 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
14583 Get hardware address with getifaddrs if available.
14585 2011-08-12 Eli Zaretskii <eliz@gnu.org>
14587 * xdisp.c (iterate_out_of_display_property): xassert that
14588 IT->position is set to within IT->object's boundaries. Break from
14589 the loop as soon as EOB is reached; avoids infloops in redisplay
14590 when IT->position is set up wrongly due to some bug.
14591 Set IT->current to match the bidi iterator unconditionally.
14592 (push_display_prop): Allow GET_FROM_STRING as IT->method on
14593 entry. Force push_it to save on the stack the current
14594 buffer/string position, to be restored by pop_it. Fix flags in
14595 the iterator structure wrt the object coming from a display
14596 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14597 properties. (Bug#9284)
14599 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
14601 * fontset.c (fontset_get_font_group): Add proper type checks.

14629 restore_point_unwind (Bug#5984).
14631 2011-08-07 Juri Linkov <juri@jurta.org>
14633 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'

14638 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
14639 display property strides EOL and includes a newline, as in
14640 longlines-mode. (Bug#9254)
14641 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
14642 word-wrap under bidirectional display. (Bug#9224)
14644 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
14645 is non-zero, even if the data buffer is NULL. Fixes a crash in
14646 vertical-motion with longlines-mode. (Bug#9254)
14648 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14650 * bidi.c <bidi_cache_total_alloc>: Now static.

14656 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
14657 amount allocated this far in `bidi_cache_total_alloc'.
14658 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
14659 non-zero, only free the data buffer without restoring the cache
14660 contents. All callers changed.
14662 * dispextern.h (bidi_unshelve_cache): Update prototype.
14664 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)

14667 to xfree to an equivalent call to bidi_unshelve_cache.
14668 (move_it_in_display_line_to): Fix logic of returning
14669 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
14671 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14673 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that

14725 DISP_PROP_P, and pass it to compute_display_string_pos.
14726 Only handle text covered by a display string if DISP_PROP_P is returned
14727 non-zero. All callers of bidi_fetch_char changed.

14740 * lisp.h (uniprop_table): Extern it.
14742 * chartab.c (uniprop_table): Make it non-static.
14744 2011-08-01 Eli Zaretskii <eliz@gnu.org>
14746 * xdisp.c (forward_to_next_line_start): Accept additional argument
14747 BIDI_IT_PREV, and store into it the state of the bidi iterator had
14749 (reseat_at_next_visible_line_start): Use the bidi iterator state
14750 returned by forward_to_next_line_start to restore the state of
14751 it->bidi_it after backing up to previous newline. (Bug#9212)
14753 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
14755 * regex.c (re_comp): Protoize.
14756 (re_exec): Fix return type.
14757 (regexec): Fix type of `ret'. (Bug#9203)
14759 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14761 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
14762 This is needed if max-image-size is a floating-point number.
14764 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14766 * print.c (print_object): Print empty symbol as ##.
14768 * lread.c (read1): Read ## as empty symbol.
14770 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14772 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
14773 setting frame foreground color (Bug#9175).
14774 (x_set_background_color): Likewise.
14776 * nsmenu.m (-setText): Size tooltip dimensions precisely to
14777 contents (Bug#9176).
14778 (EmacsTooltip -init): Remove bezels and add shadows to
14781 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
14782 or scroll bar (Bug#8470).
14784 * nsfont.m (nsfont_open): Remove assignment to voffset and
14785 unnecessary vars hshink, expand, hd, full_height, min_height.
14786 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
14788 * nsterm.h (nsfont_info): Remove voffset field.
14790 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14792 Implement strike-through and overline on NextStep (Bug#8863).
14794 * nsfont.m (nsfont_open): Use underline position provided by font,
14795 instead of hard-coded value of 2.
14796 (nsfont_draw): Call ns_draw_text_decoration instead.
14798 * nsterm.h: Add declaration for ns_draw_text_decoration.
14800 * nsterm.m (ns_draw_text_decoration): New function for drawing
14801 underline, overline, and strike-through.
14802 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
14803 ns_draw_text_decoration. Change treatment of cursor drawing to
14804 accommodate underlining, etc.
14806 2011-07-28 Eli Zaretskii <eliz@gnu.org>
14808 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
14811 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14813 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
14814 Without this fix, if a signal arrives just after memory fills up,
14815 'malloc' might be invoked reentrantly.
14817 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
14818 In other words, assume that every image size is allowed, on non-X
14819 hosts. This assumption is probably wrong, but it lets Emacs compile.
14821 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14823 * regex.c (re_iswctype): Convert return values to boolean.
14825 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
14827 * xdisp.c (compute_display_string_pos): Don't use cached display
14828 string position if the buffer had its restriction changed.
14831 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14833 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14835 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14837 Integer signedness and overflow and related fixes. (Bug#9079)
14839 * bidi.c: Integer size and overflow fixes.
14840 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
14841 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
14842 (bidi_cache_find_level_change, bidi_cache_ensure_space)
14843 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
14844 (bidi_find_other_level_edge):
14845 Use ptrdiff_t instead of EMACS_INT where either will do.
14846 This works better on 32-bit hosts configured --with-wide-int.
14847 (bidi_cache_ensure_space): Check for size-calculation overflow.
14848 Use % rather than repeated addition, for better worst-case speed.
14849 Don't set bidi_cache_size until after xrealloc returns, because it
14851 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
14852 (bidi_cache_ensure_space): Also check that the bidi cache size
14853 does not exceed that of the largest Lisp string or buffer. See Eli
14854 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
14856 * alloc.c (__malloc_size_t): Remove.
14857 All uses replaced by size_t. See Andreas Schwab's note
14858 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
14860 * image.c: Improve checking for integer overflow.
14861 (check_image_size): Assume that f is nonnull, since
14862 it is always nonnull in practice. This is one less thing to
14863 worry about when checking for integer overflow later.
14864 (x_check_image_size): New function, which checks for integer
14865 overflow issues inside X.
14866 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
14867 This removes the need for a memory_full check.
14868 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
14869 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
14870 (xbm_read_bitmap_data): Change locals back to 'int', since
14871 their values must fit in 'int'.
14872 (xpm_load_image, png_load, tiff_load):
14873 Invoke x_create_x_image_and_pixmap earlier,
14874 to avoid much needless work if the image is too large.
14875 (tiff_load): Treat overly large images as if
14876 x_create_x_image_and_pixmap failed, not as malloc failures.
14877 (gs_load): Use x_check_image_size.
14879 * gtkutil.c: Omit integer casts.
14880 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
14881 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
14883 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
14885 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
14886 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
14887 would wrongly return t on a 64-bit host.
14889 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
14890 The plain *_OVERFLOW macros run afoul of GCC bug 49705
14891 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
14892 and therefore cause GCC to emit a bogus diagnostic in some cases.
14894 * image.c: Integer signedness and overflow and related fixes.
14895 This is not an exhaustive set of fixes, but it's time to
14896 record what I've got.
14897 (lookup_pixel_color, check_image_size): Remove redundant decls.
14898 (check_image_size): Don't assume that arbitrary EMACS_INT values
14899 fit in 'int', or that arbitrary 'double' values fit in 'int'.
14900 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
14901 (tiff_load, imagemagick_load_image):
14902 Check for overflow in size calculations.
14903 (x_create_x_image_and_pixmap): Remove unnecessary test for
14904 xmalloc returning NULL; that can't happen.
14905 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
14906 (xpm_color_bucket): Use better integer hashing function.
14907 (xpm_cache_color): Don't possibly over-allocate memory.
14908 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
14909 (gif_memory_source):
14910 Use ptrdiff_t, not int or size_t, to record sizes.
14911 (png_load): Don't assume values greater than 2**31 fit in 'int'.
14912 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
14913 either works, as we prefer signed integers.
14914 (tiff_read_from_memory, tiff_write_from_memory):
14915 Return tsize_t, not size_t, since that's what the TIFF API wants.
14916 (tiff_read_from_memory): Don't fail simply because the read would
14917 go past EOF; instead, return a short read.
14918 (tiff_load): Omit no-longer-needed casts.
14919 (Fimagemagick_types): Don't assume size fits into 'int'.
14921 Improve hashing quality when configured --with-wide-int.
14922 * fns.c (hash_string): New function, taken from sxhash_string.
14923 Do not discard information about ASCII character case; this
14924 discarding is no longer needed.
14925 (sxhash-string): Use it. Change sig to match it. Caller changed.
14926 * lisp.h: Declare it.
14927 * lread.c (hash_string): Remove, since we now use fns.c's version.
14928 The fns.c version returns a wider integer if --with-wide-int is
14929 specified, so this should help the quality of the hashing a bit.
14931 * emacs.c: Integer overflow minor fix.
14932 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
14933 Define only if GNU_LINUX.
14934 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
14936 * dispnew.c: Integer signedness and overflow fixes.
14937 Remove unnecessary forward decls, that were a maintenance hassle.
14938 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
14940 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
14941 (scrolling_window): Use ptrdiff_t, not int, for byte count.
14942 (prepare_desired_row, line_draw_cost):
14943 Use int, not unsigned, where either works.
14944 (save_current_matrix, restore_current_matrix):
14945 Use ptrdiff_t, not size_t, where either works.
14946 (init_display): Check for overflow more accurately, and without
14947 relying on undefined behavior.
14949 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
14950 Remove, replacing with the new symbols in lisp.h. All uses changed.
14951 * fileio.c (make_temp_name):
14952 * filelock.c (lock_file_1, lock_file):
14953 * xdisp.c (message_dolog):
14954 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
14955 Use pMd etc. instead.
14956 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
14957 replacing the pWIDE etc. symbols removed from editfns.c.
14959 * keyboard.h (num_input_events): Now uintmax_t.
14960 This is (very slightly) less likely to mess up due to wraparound.
14963 * buffer.c: Integer signedness fixes.
14964 (alloc_buffer_text, enlarge_buffer_text):
14965 Use ptrdiff_t rather than size_t when either will do, as we prefer
14968 * alloc.c: Integer signedness and overflow fixes.
14969 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
14970 (__malloc_size_t): Default to size_t, not to int.
14971 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
14972 (Fgarbage_collect, mark_object_loop_halt, mark_object):
14973 Prefer ptrdiff_t to size_t when either would do, as we prefer
14975 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
14976 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
14977 Now const. Initialize with values that are in range even if char
14979 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
14980 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
14981 These functions do the right thing with sizes > 2**32.
14982 (check_depth): Now ptrdiff_t, not int.
14983 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
14984 Adjust to new way of storing sizes. Check for size overflow bugs
14986 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
14987 slightly wrong anyway, as it missed one instance of
14988 XMALLOC_OVERRUN_CHECK_OVERHEAD.
14989 (refill_memory_reserve): Omit needless cast to size_t.
14990 (mark_object_loop_halt): Mark as externally visible.
14992 * xselect.c: Integer signedness and overflow fixes.
14993 (Fx_register_dnd_atom, x_handle_dnd_message):
14994 Use ptrdiff_t, not size_t, since we prefer signed.
14995 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
14996 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
14997 x_dnd_atoms_size and x_dnd_atoms_length.
14999 * doprnt.c: Prefer signed to unsigned when either works.
15001 * doprnt.c (doprnt):
15003 * xdisp.c (vmessage):
15004 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15005 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15006 prefer signed arithmetic to avoid comparison confusion.
15007 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15008 but is a bit tricky.
15010 Assume freestanding C89 headers, string.h, stdlib.h.
15011 * data.c, doprnt.c, floatfns.c, print.c:
15012 Include float.h unconditionally.
15013 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15014 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15015 * regex.c: Likewise for stddef.h, string.h.
15016 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15017 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15018 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15019 (STDC_HEADERS): Remove obsolete defines.
15020 * sysdep.c: Include limits.h unconditionally.
15022 Assume support for memcmp, memcpy, memmove, memset.
15023 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
15024 * regex.c (memcmp, memcpy):
15025 Remove; we assume C89 now.
15027 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
15028 (__malloc_safe_bcopy): Remove; no longer needed.
15030 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
15031 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
15032 well either way, and we prefer signed to unsigned.
15034 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
15036 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
15037 closes the connection while we're reading (bug#9182).
15039 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
15041 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
15042 are specified (Bug#9168).
15044 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
15046 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15047 Found by GCC static checking and --with-wide-int on a 32-bit host.
15049 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15051 * xdisp.c (compute_display_string_pos): Fix logic of caching
15052 previous display string position. Initialize cached_prev_pos to
15053 -1. Fixes slow-down at the beginning of a buffer.
15055 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15057 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15058 for attrs[LFACE_FONTSET_INDEX].
15060 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15062 * xml.c (parse_region): Remove unused local
15063 that was recently introduced.
15065 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15067 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15068 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15070 * xdisp.c (move_it_in_display_line_to): Record the best matching
15071 position for TO_CHARPOS while scanning the line, and restore it on
15072 exit if none of the characters scanned was an exact match.
15073 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15074 when exact match is impossible due to invisible text, and the
15075 lines are truncated.
15077 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15079 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15082 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15084 Fix a significant slow-down of cursor motion with C-n, C-p,
15085 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15086 auto-repeat under bidi redisplay in fontified buffers.
15087 * xdisp.c (compute_stop_pos_backwards): New function.
15088 (next_element_from_buffer): Call compute_stop_pos_backwards to
15089 find a suitable prev_stop when we find ourselves before
15091 (reseat): Don't look for prev_stop, as that could mean a very long
15093 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15094 <cached_disp_overlay_modiff>: Cache for last found display string
15096 (compute_display_string_pos): Return the cached position if asked
15097 about the same buffer in the same area of character positions, and
15098 the buffer wasn't changed since the time the display string
15099 position was cached.
15101 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15103 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15104 is an integer, which is important for empty lines. (Bug#9149)
15106 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15108 * frame.c (Fmodify_frame_parameters): In tty case, update the
15109 default face if necessary (Bug#4238).
15111 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15113 * editfns.c (Fstring_to_char): No need to explain what a character
15114 is in the docstring (Bug#6576).
15116 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15118 * xml.c (parse_region): Make sure we always return a tree.
15120 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15122 * xml.c (parse_region): If a document contains only comments,
15125 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15127 * xml.c (make_dom): Return comments, too.
15129 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15132 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15133 and the surrounding thread.
15134 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15135 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15136 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15138 * s/openbsd.h (BROKEN_SIGIO): Define.
15139 * unexelf.c (unexec) [__OpenBSD__]:
15140 Don't update the .mdebug section of the Alpha COFF symbol table.
15142 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15144 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15147 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15149 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15150 This fixes some race conditions on the permissions of any newly
15153 * alloc.c (valid_pointer_p): Use pipe, not open.
15154 This fixes some permissions issues when debugging.
15156 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15157 If fchown fails to set both uid and gid, try to set just gid,
15158 as that is sometimes allowed. Adjust the file's mode to eliminate
15159 setuid or setgid bits that are inappropriate if fchown fails.
15161 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
15163 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
15164 to compare Lisp_Objects.
15165 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
15166 global_gnutls_log_level, don't mistake it for a Lisp_Object.
15167 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
15169 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
15171 * lread.c (read_integer): Unread even EOF character.
15172 (read1): Likewise. Properly record start position of symbol.
15174 * lread.c (read1): Read `#:' as empty uninterned symbol if no
15175 symbol character follows.
15177 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
15179 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15180 This works around a problem with the previous change to Fcopy_file.
15181 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15182 and without this change, GCC might complain about discarding

15281 the iterator is before prev_stop.
15282 (init_iterator): Initialize bidi_p from the default value of

15800 Random fixes. E.g., (random) never returned negative values.
15801 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
15802 subseconds part to the entropy, as that's a bit more random.
15803 Prefer signed to unsigned, since the signedness doesn't matter and
15804 in general we prefer signed. When given a limit, use a
15805 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
15806 latter isn't right if USE_2_TAGS_FOR_INTS.
15807 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
15808 not 0..VALMASK. Don't discard "excess" bits that random () returns.

15832 error be more correct.
15834 * fns.c (Frequire): Remove the mention of the .gz files, since

15851 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
15852 Also (re)move comments that are misplaced or no longer relevant.

15953 * eval.c (struct backtrace): Simplify and port the data structure.
15954 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
15955 signed bit field, as this assumption is not portable and it makes
15956 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
15957 "char debug_on_exit : 1" as this is not portable either; instead,
15958 use the portable "unsigned int debug_on_exit : 1". Remove unused
15959 member evalargs. Remove obsolete comments about cc bombing out.

16123 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
16125 Integer and buffer overflow fixes (Bug#8873).
16127 * print.c (printchar, strout): Check for string overflow.
16128 (PRINTPREPARE, printchar, strout):
16129 Don't set size unless allocation succeeds.
16131 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
16132 for sizes. Check for string overflow more accurately.
16133 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
16135 * macros.c: Integer and buffer overflow fixes.
16136 * keyboard.h (struct keyboard.kbd_macro_bufsize):
16137 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
16138 Use ptrdiff_t, not int, for sizes.
16139 Don't increment bufsize until after realloc succeeds.
16140 Check for size-calculation overflow.
16141 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
16143 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
16145 * lread.c: Integer overflow fixes.
16146 (read_integer): Radix is now EMACS_INT, not int,
16147 to improve quality of diagnostics for out-of-range radices.
16148 Calculate buffer size correctly for out-of-range radices.
16149 (read1): Check for integer overflow in radices, and in
16150 read-circle numbers.
16151 (read_escape): Avoid int overflow.
16152 (Fload, openp, read_buffer_size, read1)
16153 (substitute_object_recurse, read_vector, read_list, map_obarray):
16154 Use ptrdiff_t, not int, for sizes.

16169 2011-06-22 Leo Liu <sdl.web@gmail.com>
16171 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
16172 Move to minibuffer.el.
16174 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16176 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
16177 The following patches are for when GLYPH_DEBUG && !XASSERT.
16178 * dispextern.h (trace_redisplay_p, dump_glyph_string):
16179 * dispnew.c (flush_stdout):
16180 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16181 Mark as externally visible.
16182 * dispnew.c (check_window_matrix_pointers): Now static.
16183 * dispnew.c (window_to_frame_vpos):
16184 * xfns.c (unwind_create_frame):
16185 * xterm.c (x_check_font): Remove unused local.
16186 * scroll.c (CHECK_BOUNDS):
16187 * xfaces.c (cache_fache): Rename local to avoid shadowing.
16188 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
16189 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
16190 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
16191 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16193 (debug_method_add): Use va_list and vsprintf rather than relying
16194 on undefined behavior with wrong number of arguments.
16195 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16196 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16197 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16198 since we're not interested in debugging glyphs with old libraries.
16199 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16200 GCC 4.6.0's static checking.
16202 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16204 Integer overflow and signedness fixes (Bug#8873).

16215 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
16216 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
16218 * xfaces.c (load_pixmap):

16220 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
16221 (.bitmaps_last, struct x_output.icon_bitmap):
16222 Use ptrdiff_t, not int, for bitmap indexes.
16223 (x_allocate_bitmap_record): Check for size overflow.
16224 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
16226 Use ptrdiff_t, not int, for overlay counts.
16227 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
16228 * editfns.c (overlays_around, get_pos_property):
16229 * textprop.c (get_char_property_and_overlay):
16230 * xdisp.c (next_overlay_change, note_mouse_highlight):
16231 * xfaces.c (face_at_buffer_position):
16232 * buffer.c (OVERLAY_COUNT_MAX): New macro.
16233 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
16234 (Fnext_overlay_change, Fprevious_overlay_change)
16235 (mouse_face_overlay_overlaps, Foverlays_in):
16236 Use ptrdiff_t, not int, for sizes.
16237 (overlays_at, overlays_in): Check for size-calculation overflow.
16239 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
16241 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
16242 (x_session_initialize): Do not assume string length fits in int.
16244 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16245 This is unlikely, but can occur if DPI is outlandish.
16247 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
16248 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
16250 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
16251 * xrdb.c (magic_file_p, search_magic_path):
16252 Omit last arg SUFFIX; it was always 0. All callers changed.
16253 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
16255 * xfont.c (xfont_match): Avoid need for strlen.
16257 * xfns.c: Don't assume strlen fits in int.
16258 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
16260 * xdisp.c (message_log_check_duplicate): Return intmax_t,
16261 not unsigned long, as we prefer signed integers. All callers changed.
16262 Detect integer overflow in repeat count.
16263 (message_dolog): Don't assume print length fits in 39 bytes.
16264 (display_mode_element): Don't assume strlen fits in int.
16266 * termcap.c: Don't assume sizes fit in int and never overflow.
16267 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
16268 (gobble_line): Check for size-calculation overflow.
16270 * minibuf.c (Fread_buffer):
16271 * lread.c (intern, intern_c_string):
16272 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

16276 * gtkutil.c (style_changed_cb): Avoid need for strlen.
16278 * font.c: Don't assume string length fits in int.
16279 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
16280 Use ptrdiff_t, not int.
16281 (font_intern_prop): Don't assume string length fits in int.
16282 Don't assume integer property fits in fixnum.
16283 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
16285 * filelock.c: Fix some buffer overrun and integer overflow issues.
16286 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16287 Reformulate so as not to need the command string.
16288 Invoke gzip -cd rather than gunzip, as it's more portable.
16289 (lock_info_type, lock_file_1, lock_file):
16290 Don't assume pid_t and time_t fit in unsigned long.
16291 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16292 (current_lock_owner): Prefer signed type for sizes.
16293 Use memcpy, not strncpy, where memcpy is what is really wanted.
16294 Don't assume (via atoi) that time_t and pid_t fit in int.
16295 Check for time_t and/or pid_t out of range, e.g., via a network share.
16296 Don't alloca where an auto var works fine.
16298 * fileio.c: Fix some integer overflow issues.
16299 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16300 Don't assume string length fits in int.
16301 (directory_file_name): Don't assume string length fits in long.
16302 (make_temp_name): Don't assume pid fits in int, or that its print
16303 length is less than 20.
16305 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16307 * coding.c (make_subsidiaries): Don't assume string length fits in int.
16309 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
16311 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
16312 We prefer signed integers, even for size calculations.
16314 * emacs.c: Don't assume string length fits in 'int'.
16315 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
16316 (main): Don't invoke strlen when not needed.
16318 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.

16321 * callproc.c (getenv_internal_1, getenv_internal)
16322 (Fgetenv_internal):
16323 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16325 * lread.c (invalid_syntax): Omit length argument.
16326 All uses changed. This doesn't fix a bug, but it simplifies the
16327 code away from its former Hollerith-constant appearance, and it's
16328 one less 'int' to worry about when looking at integer-overflow issues.
16329 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16331 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16332 This didn't break anything, but it didn't help either.
16333 It's confusing to put a bogus integer in a place where the actual
16334 value does not matter.
16335 (LIST_END_P): Remove unused macro and its bogus comment.
16336 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16338 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16339 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16341 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16342 We prefer signed types, and the value cannot exceed the EMACS_INT
16343 range anyway (because otherwise the length would not be representable).
16344 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16345 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16346 This avoids a GCC warning when WIDE_EMACS_INT.
16348 * indent.c (sane_tab_width): New function.
16349 (current_column, scan_for_column, Findent_to, position_indentation)
16350 (compute_motion): Use it. This is just for clarity.
16351 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16353 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16355 * lisp.h (lint_assume): New macro.
16356 * composite.c (composition_gstring_put_cache):
16357 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16359 * editfns.c, insdel.c:
16360 Omit unnecessary forward decls, to simplify future changes.
16362 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16364 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16366 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16367 Use much-faster test for byte-length change.
16368 Don't assume string byte-length fits in 'int'.
16369 Check that character arg fits in 'int'.
16370 (mapcar1): Declare byte as byte, for clarity.
16372 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16374 * fns.c (concat): Catch string overflow earlier.
16375 Do not rely on integer wraparound.
16377 * dispextern.h (struct it.overlay_strings_charpos)
16378 (struct it.selective): Now EMACS_INT, not int.
16379 * xdisp.c (forward_to_next_line_start)
16380 (back_to_previous_visible_line_start)
16381 (reseat_at_next_visible_line_start, next_element_from_buffer):
16382 Don't arbitrarily truncate the value of 'selective' to int.
16384 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16386 * composite.c: Don't truncate sizes to 'int'.
16387 (composition_gstring_p, composition_reseat_it)
16388 (composition_adjust_point): Use EMACS_INT, not int.
16389 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16390 not EMACS_UINT, for indexes.
16392 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16394 * buffer.c: Include <verify.h>.
16395 (struct sortvec.priority, struct sortstr.priority):
16396 Now EMACS_INT, not int.
16397 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16398 (struct sortstr.size, record_overlay_string)
16399 (struct sortstrlist.size, struct sortlist.used):
16400 Don't truncate size to int.
16401 (record_overlay_string): Check for size-calculation overflow.
16402 (init_buffer_once): Check at compile-time, not run-time.
16404 2011-06-22 Jim Meyering <meyering@redhat.com>
16406 Don't leak an XBM-image-sized buffer
16407 * image.c (xbm_load): Free the image buffer after using it.
16409 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16412 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16413 that Sun C diagnosed.
16414 * fns.c (secure_hash): Fix pointer signedness issue.
16415 * intervals.c (static_offset_intervals): New function.
16416 (offset_intervals): Use it.
16418 2011-06-21 Leo Liu <sdl.web@gmail.com>
16421 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16424 * fns.c (secure_hash): Rename from crypto_hash_function and change
16425 the first arg to accept symbols.
16426 (Fsecure_hash): New primitive.
16427 (syms_of_fns): New symbols.
16429 2011-06-20 Deniz Dogan <deniz@dogan.se>
16431 * process.c (Fset_process_buffer): Clarify return value in
16434 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
16436 * dispnew.c (add_window_display_history): Use BVAR.
16438 * xdisp.c (debug_method_add): Use BVAR.
16439 (check_window_end, dump_glyph_matrix, dump_glyph)
16440 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
16442 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
16445 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
16446 check till after the cache is created in init_frame_faces.
16448 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
16450 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
16452 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
16454 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
16455 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
16456 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
16458 Improve buffer-overflow checking (Bug#8873).
16459 * fileio.c (Finsert_file_contents):
16460 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
16461 Remove the old (too-loose) buffer overflow checks.
16462 They weren't needed, since make_gap checks for buffer overflow.
16463 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
16464 The old code merely checked for Emacs fixnum overflow, and relied
16465 on undefined (wraparound) behavior. The new code avoids undefined
16466 behavior, and also checks for ptrdiff_t and/or size_t overflow.
16468 * editfns.c (Finsert_char): Don't dump core with very negative counts.
16469 Tune. Don't use wider integers than needed. Don't use alloca.
16470 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
16472 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
16474 * insdel.c, lisp.h (buffer_overflow): New function.
16475 (insert_from_buffer_1, replace_range, replace_range_2):
16476 * insdel.c (make_gap_larger):
16477 * editfns.c (Finsert_char):
16478 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
16480 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
16482 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
16484 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
16486 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
16487 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
16489 * fileio.c: Don't assume EMACS_INT fits in off_t.
16490 (emacs_lseek): New static function.
16491 (Finsert_file_contents, Fwrite_region): Use it.
16492 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
16494 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
16496 * fns.c: Don't overflow int when computing a list length.
16497 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
16498 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
16499 truncation on 64-bit hosts. Check for QUIT every
16500 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
16501 faster and is responsive enough.
16502 (Flength): Report an error instead of overflowing an integer.
16503 (Fsafe_length): Return a float if the value is not representable
16504 as a fixnum. This shouldn't happen except in contrived situations.
16505 (Fnthcdr, Fsort): Don't assume list length fits in int.
16506 (Fcopy_sequence): Don't assume vector length fits in int.
16508 * alloc.c: Check that resized vectors' lengths fit in fixnums.
16509 (header_size, word_size): New constants.
16510 (allocate_vectorlike): Don't check size overflow here.
16511 (allocate_vector): Check it here instead, since this is the only
16512 caller of allocate_vectorlike that could cause overflow.
16513 Check that the new vector's length is representable as a fixnum.
16515 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16516 The previous code was bogus. For example, next_almost_prime (32)
16517 returned 39, which is undesirable as it is a multiple of 3; and
16518 next_almost_prime (24) returned 25, which is a multiple of 5 so
16519 why was the code bothering to check for multiples of 7?
16521 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16523 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16525 Variadic C functions now count arguments with ptrdiff_t.
16526 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16527 Back then I didn't know that the Emacs coding style prefers signed int.
16528 Also, in the meantime I found a few more instances where arguments
16529 were being counted with int, which may truncate counts on 64-bit
16530 machines, or EMACS_INT, which may be unnecessarily wide.
16531 * lisp.h (struct Lisp_Subr.function.aMANY)
16532 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16533 Arg counts are now ptrdiff_t, not size_t.
16534 All variadic functions and their callers changed accordingly.
16535 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16536 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16537 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16538 * callint.c (Fcall_interactively): Check arg count for overflow,
16539 to avoid potential buffer overrun. Use signed char, not 'int',
16540 for 'varies' array, so that we needn't bother to check its size
16541 calculation for overflow.
16542 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16543 * eval.c (apply_lambda):
16544 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16545 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16546 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16548 * callint.c (Fcall_interactively): Don't use index var as event count.
16550 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16551 * mem-limits.h (SIZE): Remove; no longer used.
16553 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16555 Remove unnecessary casts.
16556 * xterm.c (x_term_init):
16557 * xfns.c (x_set_border_pixel):
16558 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16559 These aren't needed now that we assume ANSI C.
16561 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16562 It's more likely to cause problems (due to unsigned overflow)
16565 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16567 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16569 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16571 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16573 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16575 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16577 GLYPH_CODE_FACE returns EMACS_INT, not int.
16578 * dispextern.h (merge_faces):
16579 * xfaces.c (merge_faces):
16580 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16581 Don't assume EMACS_INT fits in int.
16583 * character.h (CHAR_VALID_P): Remove unused parameter.
16584 * fontset.c, lisp.h, xdisp.c: All uses changed.
16586 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16588 * fns.c (concat): Minor tuning based on overflow analysis.
16589 This doesn't fix any bugs. Use int to hold character, instead
16590 of constantly refetching from Emacs object. Use XFASTINT, not
16591 XINT, for value known to be a character. Don't bother comparing
16592 a single byte to 0400, as it's always less.
16594 * floatfns.c (Fexpt):
16595 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16597 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16600 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16602 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16603 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16604 incorrectly succeed when S was a string, because 4294967386 was
16605 truncated before it was used.
16607 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16608 Otherwise, an out-of-range integer could cause undefined behavior
16611 * composite.c: Use int, not EMACS_INT, for characters.
16612 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16613 EMACS_INT, for values that are known to be in character range.
16614 This doesn't fix any bugs but is the usual style inside Emacs and
16615 may generate better code on 32-bit machines.
16617 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16618 This is for reasons similar to the recent CHAR_STRING fix.
16619 * charset.c (Fencode_char): Check that character arg is actually
16620 a character. Pass an int to ENCODE_CHAR.
16621 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16622 wider than 'int', as a compile-time check to prevent future regressions
16625 * character.c (char_string): Remove unnecessary casts.
16627 Make sure a 64-bit char is never passed to CHAR_STRING.
16628 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16629 by silently ignoring the top 32 bits, allowing some values
16630 that were far too large to be valid characters.
16631 * character.h: Include <verify.h>.
16632 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
16633 arguments are no wider than unsigned, as a compile-time check
16634 to prevent future regressions in this area.
16636 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
16637 (Fsubst_char_in_region):
16639 * xdisp.c (decode_mode_spec_coding):
16640 Adjust to CHAR_STRING's new requirement.
16641 * editfns.c (Finsert_char, Fsubst_char_in_region):
16642 * fns.c (concat): Check that character args are actually
16643 characters. Without this test, these functions did the wrong
16644 thing with wildly out-of-range values on 64-bit hosts.
16646 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
16647 These casts should not be needed on 32-bit hosts, either.
16648 * keyboard.c (read_char):
16649 * lread.c (Fload): Remove casts to unsigned.
16651 * lisp.h (UNSIGNED_CMP): New macro.
16652 This fixes comparison bugs on 64-bit hosts.
16653 (ASCII_CHAR_P): Use it.
16654 * casefiddle.c (casify_object):
16655 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
16656 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
16657 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
16658 * dispextern.h (FACE_FROM_ID):
16659 * keyboard.c (read_char): Use UNSIGNED_CMP.
16661 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
16662 not to EMACS_INT, to avoid GCC warning.
16664 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
16666 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
16667 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
16668 isn't needed on 32-bit machines.
16670 * buffer.c (Fgenerate_new_buffer_name):
16671 Use EMACS_INT for count, not int.
16672 (advance_to_char_boundary): Return EMACS_INT, not int.
16674 * data.c (Qcompiled_function): Now static.
16676 * window.c (window_body_lines): Now static.
16678 * image.c (gif_load): Rename local to avoid shadowing.
16680 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
16681 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
16682 * alloc.c (make_save_value): Integer argument is now of type
16683 ptrdiff_t, not int.
16684 (mark_object): Use ptrdiff_t, not int.
16685 * lisp.h (pD): New macro.
16686 * print.c (print_object): Use it.
16688 * alloc.c: Use EMACS_INT, not int, to count objects.
16689 (total_conses, total_markers, total_symbols, total_vector_size)
16690 (total_free_conses, total_free_markers, total_free_symbols)
16691 (total_free_floats, total_floats, total_free_intervals)
16692 (total_intervals, total_strings, total_free_strings):
16693 Now EMACS_INT, not int. All uses changed.
16694 (Fgarbage_collect): Compute overall total using a double, so that
16695 integer overflow is less likely to be a problem. Check for overflow
16696 when converting back to an integer.
16697 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
16698 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
16699 These were 'int' variables that could overflow on 64-bit hosts;
16700 they were never used, so remove them instead of repairing them.
16701 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
16702 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
16703 Previously, this ceilinged at INT_MAX, but that doesn't work on
16705 (allocate_pseudovector): Don't use EMACS_INT when int would do.
16707 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
16708 (allocate_vectorlike): Check for ptrdiff_t overflow.
16709 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
16710 when a (possibly-narrower) signed value would do just as well.
16711 We prefer using signed arithmetic, to avoid comparison confusion.
16713 * alloc.c: Catch some string size overflows that we were missing.
16714 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
16715 for convenience in STRING_BYTES_MAX.
16716 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
16717 The definition here is exact; the one in lisp.h was approximate.
16718 (allocate_string_data): Check for string overflow. This catches
16719 some instances we weren't catching before. Also, it catches
16720 size_t overflow on (unusual) hosts where SIZE_MAX <= min
16721 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
16722 and ptrdiff_t and EMACS_INT are both 64 bits.
16724 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
16725 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
16726 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
16728 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
16730 * alloc.c (Fmake_string): Check for out-of-range init.
16732 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
16734 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
16736 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
16738 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
16739 xg_get_default_scrollbar_width.
16741 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
16742 (int_gtk_range_get_value): Move to the scroll bar part of the file.
16743 (style_changed_cb): Call update_theme_scrollbar_width and call
16744 x_set_scroll_bar_default_width and xg_frame_set_char_size for
16745 all frames (Bug#8505).
16746 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
16747 Call gtk_window_set_resizable if HAVE_GTK3.
16748 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
16749 and height if HAVE_GTK3 (Bug#8505).
16750 (scroll_bar_width_for_theme): New variable.
16751 (update_theme_scrollbar_width): New function.
16752 (xg_get_default_scrollbar_width): Move code to
16753 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
16754 (xg_initialize): Call update_theme_scrollbar_width.
16756 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
16758 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
16760 2011-06-12 Martin Rudalics <rudalics@gmx.at>
16762 * frame.c (make_frame): Call other_buffer_safely instead of
16765 * window.c (temp_output_buffer_show): Call display_buffer with
16766 second argument Vtemp_buffer_show_specifiers and reset latter
16767 immediately after the call.
16768 (Vtemp_buffer_show_specifiers): New variable.
16769 (auto_window_vscroll_p, next_screen_context_lines)
16770 (Vscroll_preserve_screen_position): Remove leading asterisks from
16773 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
16775 Fix minor problems found by GCC 4.6.0 static checking.
16776 * buffer.c (Qclone_number): Remove for now, as it's unused.
16777 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
16778 (record_buffer): Remove unused local.
16779 * frame.c (other_visible_frames, frame_buffer_list): Now static.
16780 (set_frame_buffer_list): Remove; unused.
16781 * frame.h (other_visible_frames): Remove decl.
16782 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
16783 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
16784 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
16786 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
16787 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
16788 Define only if HAVE_GPM.
16789 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
16790 (update_hints_inhibit): Remove; never set. All uses removed.
16791 * widgetprv.h (emacsFrameClassRec): Remove decl.
16792 * window.c (delete_deletable_window): Now returns void, since it
16793 wasn't returning anything.
16794 (compare_window_configurations): Remove unused locals.
16795 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
16796 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
16797 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
16798 the same widths as pointers. This follows up on the 2011-05-06 patch.
16799 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
16800 * xterm.h: Likewise.
16801 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.

16806 (LISP_H): Add lib/intprops.h.
16808 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
16810 * image.c (gif_load): Add animation frame delay to the metadata.
16811 (syms_of_image): Use DEFSYM. New symbol `delay'.
16813 2011-06-11 Martin Rudalics <rudalics@gmx.at>
16815 * window.c (delete_deletable_window): Re-add.
16816 (Fset_window_configuration): Rewrite to handle dead buffers and
16817 consequently deletable windows.
16818 (window_tree, Fwindow_tree): Remove. Supply functionality in
16820 (compare_window_configurations): Simplify code.
16822 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
16824 * image.c (imagemagick_load_image): Fix type mismatch.
16825 (Fimagemagick_types): Likewise.
16827 * window.h (replace_buffer_in_windows): Declare.
16829 2011-06-11 Martin Rudalics <rudalics@gmx.at>
16831 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
16832 Qclone_number. Remove external declaration of Qdelete_window.
16833 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
16835 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
16836 Run Qbuffer_list_update_hook if allowed.
16837 (Fother_buffer): Rewrite doc-string. Major rewrite for new
16838 buffer list implementation.
16839 (other_buffer_safely): New function.
16840 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
16841 calls to replace_buffer_in_windows and
16842 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
16844 (record_buffer): Inhibit quitting and rewrite using quittable
16845 functions. Run Qbuffer_list_update_hook if allowed.
16846 (Frecord_buffer, Funrecord_buffer): New functions.
16847 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
16848 Move switch-to-buffer to window.el.
16849 (bury-buffer): Move to window.el.
16850 (Vbuffer_list_update_hook): New variable.
16852 * lisp.h (other_buffer_safely): Add prototype in buffer.c
16855 * window.h (resize_frame_windows): Move up in code.
16856 (Fwindow_frame): Remove EXFUN.
16857 (replace_buffer_in_all_windows): Remove prototype.
16858 (replace_buffer_in_windows_safely): Add prototype.
16860 * window.c: Declare Qdelete_window static again. Move down
16861 declaration of select_count.
16862 (Fnext_window, Fprevious_window): Rewrite doc-strings.
16863 (Fother_window): Move to window.el.
16864 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
16865 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
16866 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
16868 (replace_buffer_in_windows): Implement by calling
16869 Qreplace_buffer_in_windows.
16870 (replace_buffer_in_all_windows): Remove with some functionality
16871 moved into replace_buffer_in_windows_safely.
16872 (replace_buffer_in_windows_safely): New function.
16873 (select_window_norecord, select_frame_norecord): Move in front
16874 of run_window_configuration_change_hook. Remove now obsolete
16876 (Fset_window_buffer): Rewrite doc-string.
16877 Call Qrecord_window_buffer.
16878 (keys_of_window): Move binding for other-window to window.el.
16880 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
16882 * dispextern.h (struct image): Replace data member, whose int_val
16883 and ptr_val fields were not used by anything, with a single
16886 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
16887 (gif_clear_image, gif_load, imagemagick_load_image)
16888 (gs_clear_image, gs_load): Callers changed.

17367 Without this change, the gnutls library would invoke malloc etc.
17368 directly, which causes problems on non-SYNC_INPUT hosts, and which
17369 runs afoul of improving memory_full behavior. (Bug#8761)
17370 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17371 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17372 xfree instead of the default malloc, realloc, free.
17373 (Fgnutls_boot): No need to check for memory allocation failure,
17374 since xmalloc does that for us.
17376 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
17377 * category.c (hash_get_category_set):

17394 * lisp.h (struct Lisp_Hash_Table):
17395 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
17396 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
17397 for hashes and hash indexes, instead of 'unsigned' and 'int'.
17398 * alloc.c (allocate_vectorlike):
17399 Check for overflow in vector size calculations.
17400 * ccl.c (ccl_driver):
17401 Check for overflow when converting EMACS_INT to int.
17402 * fns.c, image.c: Remove unnecessary static decls that would otherwise
17403 need to be updated by these changes.
17404 * fns.c (make_hash_table, maybe_resize_hash_table):
17405 Check for integer overflow with large hash tables.
17406 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17407 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17408 (SXHASH_REDUCE): New macro.
17409 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
17410 Use it instead of discarding useful hash info with large hash values.
17411 (sxhash_float): New function.
17412 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17413 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17414 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17415 Rewrite to use FIXNUM_BITS, as this simplifies things.
17416 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17417 Adjust signatures to match updated version of code.
17418 (consing_since_gc): Now EMACS_INT, since a single hash table can
17419 use more than INT_MAX bytes.
17421 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
17423 Make it possible to build with GCC-4.6+ -O2 -flto.

17435 Update dependencies.
17437 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17439 * data.c (init_data): Remove code for UTS, this system is not
17442 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17444 Don't force ./temacs to start in terminal mode.
17446 * frame.c (make_initial_frame): Initialize faces in all cases, not
17447 only when CANNOT_DUMP is defined.
17448 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
17450 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17452 * dispnew.c (add_window_display_history): Use const for the string
17453 pointer. Remove declaration, not needed.
17455 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17457 Use 'inline', not 'INLINE'.
17458 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
17459 * alloc.c, fontset.c (INLINE): Remove.
17460 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
17461 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
17462 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
17463 * gmalloc.c (register_heapinfo): Use inline unconditionally.
17464 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
17466 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17468 Make it possible to run ./temacs.
17470 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
17471 syms_of_callproc does the same thing. Remove test for
17472 "initialized", do it in the caller.
17473 * emacs.c (main): Avoid calling set_initial_environment when dumping.
17475 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
17477 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
17478 (read_minibuf): Use get_minibuffer.
17479 (syms_of_minibuf): Use DEFSYM.
17480 (Qmetadata): New var.
17481 * data.c (Qbuffer): Don't make it static.
17482 (syms_of_data): Use DEFSYM.
17484 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17486 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
17487 (CCL_CODE_MIN): New macro.
17489 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
17491 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
17493 * eval.c (Qdebug): Now static.
17494 * lisp.h (Qdebug): Remove decl. This reverts a part of the
17495 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
17496 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
17498 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17500 * image.c: Various fixes to ImageMagick code comments.
17501 (Fimagemagick_types): Doc fix.
17503 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
17505 Minor fixes prompted by GCC 4.6.0 warnings.
17507 * xselect.c (converted_selections, conversion_fail_tag): Now static.
17509 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
17510 (x_clipboard_manager_save_all): Move extern decl to ...
17511 * xterm.h: ... here, so that it can be checked for consistency.
17513 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17515 * xselect.c (x_clipboard_manager_save_frame)
17516 (x_clipboard_manager_save_all): New functions.
17517 (Fx_clipboard_manager_save): Lisp function deleted.
17519 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
17520 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
17522 * xterm.h: Update prototype.
17524 2011-05-28 William Xu <william.xwl@gmail.com>
17526 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
17527 exiting (Bug#8239).
17529 2011-05-28 Jim Meyering <meyering@redhat.com>
17531 Avoid a sign-extension bug in crypto_hash_function.
17532 * fns.c (to_uchar): Define.
17533 (crypto_hash_function): Use it to convert some newly-signed
17534 variables to unsigned, to avoid sign-extension bugs. For example,
17535 without this change, (md5 "truc") would evaluate to
17536 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17537 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
17538 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
17540 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17542 Integer overflow fixes.
17544 * dbusbind.c: Serial number integer overflow fixes.
17545 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
17546 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
17547 to hold a serial number that is too large for a fixnum.
17548 (Fdbus_method_return_internal, Fdbus_method_error_internal):
17549 Check for serial numbers out of range. Decode any serial number
17550 that was so large that it became a float. (Bug#8722)
17552 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17553 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17554 Use XFASTINT rather than XUINT when numbers are nonnegative.
17555 (xd_append_arg, Fdbus_method_return_internal):
17556 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17557 arguments, check that Lisp number is nonnegative, rather than
17558 silently wrapping negative numbers around. (Bug#8722)
17559 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17562 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17564 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17566 ccl: Add integer overflow checks.
17567 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17568 (IN_INT_RANGE): New macros.
17569 (ccl_driver): Use them to check for integer overflow when
17570 decoding a CCL program. Many of the new checks are whether XINT (x)
17571 fits in int; it doesn't always, on 64-bit hosts. The new version
17572 doesn't catch all possible integer overflows, but it's an
17573 improvement. (Bug#8719)
17575 * alloc.c (make_event_array): Use XINT, not XUINT.
17576 There's no need for unsigned here.
17578 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17579 This follows up to the 2011-05-06 change that substituted uintptr_t
17580 for EMACS_INT. This case wasn't caught back then.
17582 Rework Fformat to avoid integer overflow issues.
17583 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17584 now (part of C89). Include <verify.h>.
17585 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17586 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17587 (Fformat): Avoid the prepass trying to compute sizes; it was only
17588 approximate and thus did not catch overflow reliably. Instead, walk
17589 through the format just once, formatting and computing sizes as we go,
17590 checking for integer overflow at every step, and allocating a larger
17591 buffer as needed. Keep track separately whether the format is
17592 multibyte. Keep only the most-recently calculated precision, rather
17593 than them all. Record whether each argument has been converted to
17594 string. Use EMACS_INT, not int, for byte and char and arg counts.
17595 Support field widths and precisions larger than INT_MAX. Avoid
17596 sprintf's undefined behavior with conversion specifications such as %#d
17597 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17598 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17599 formatting out-of-range floating point numbers with int
17600 formats. (Bug#8668)
17602 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17604 * data.c: Avoid integer truncation in expressions involving floats.
17605 * data.c: Include <intprops.h>.
17606 (arith_driver): When there's an integer overflow in an expression
17607 involving floating point, convert the integers to floating point
17608 so that the resulting value does not suffer from catastrophic
17609 integer truncation. For example, on a 64-bit host (* 4
17610 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17611 Do not rely on undefined behavior after integer overflow.
17613 merge count_size_as_multibyte, parse_str_to_multibyte
17614 * character.c, character.h (count_size_as_multibyte):
17615 Rename from parse_str_to_multibyte; all uses changed.
17616 Check for integer overflow.
17617 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17618 since it's now a duplicate of the other. This is more of
17619 a character than a buffer op, so better that it's in character.c.
17620 * fns.c, print.c: Adjust to above changes.
17622 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17624 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17626 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17628 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17629 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
17630 (x_clipboard_manager_save): Now static.
17631 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
17633 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17634 (crypto_hash_function): Now static.
17635 Fix pointer signedness problems. Avoid unnecessary initializations.
17637 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
17639 * termhooks.h (Vselection_alist): Make it terminal-local.
17641 * terminal.c (create_terminal): Initialize it.
17643 * xselect.c: Support for clipboard managers.
17644 (Vselection_alist): Move to termhooks.h as terminal-local var.
17645 (LOCAL_SELECTION): New macro.
17646 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
17647 (symbol_to_x_atom): Remove gratuitous arg.
17648 (x_handle_selection_request, lisp_data_to_selection_data)
17649 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
17650 (x_own_selection, x_get_local_selection, x_convert_selection):
17651 New arg, specifying work frame. Use terminal-local Vselection_alist.
17652 (some_frame_on_display): Delete unused function.
17653 (Fx_own_selection_internal, Fx_get_selection_internal)
17654 (Fx_disown_selection_internal, Fx_selection_owner_p)
17655 (Fx_selection_exists_p): New optional frame arg.
17656 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
17657 (x_handle_selection_clear): Don't treat other terminals with the
17658 same keyboard specially. Use the terminal-local Vselection_alist.
17659 (x_clear_frame_selections): Use Frun_hook_with_args.
17661 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
17663 * xterm.h: Add support for those atoms.
17665 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
17667 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
17668 (converted_selections, conversion_fail_tag): New global variables.
17669 (x_selection_request_lisp_error): Free the above.
17670 (x_get_local_selection): Remove unnecessary code.
17671 (x_reply_selection_request): Args changed; handle arbitrary array
17672 of converted selections stored in converted_selections.
17673 Separate the XChangeProperty and SelectionNotify steps.
17674 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
17675 (x_convert_selection): New function.
17676 (x_handle_selection_event): Simplify.
17677 (x_get_foreign_selection): Don't ignore incoming requests while
17678 waiting for an answer; this will fail when we implement
17679 SAVE_TARGETS, and seems unnecessary anyway.
17680 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
17681 (Vx_sent_selection_functions): Doc fix.
17683 2011-05-26 Leo Liu <sdl.web@gmail.com>
17685 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
17687 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17689 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17691 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17692 for fringe update if it has periodic bitmap.
17693 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17694 and fringe_bitmap_periodic_p.
17696 * fringe.c (get_fringe_bitmap_data): New function.
17697 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17698 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17699 row. Mark glyph row for fringe update if periodicity changed.
17701 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17702 for fringe update unless it has periodic bitmap.

17723 Remove macros that are defined and never used.
17724 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
17726 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17728 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
17729 (Fx_get_selection_internal): Minor cleanup.

17757 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
17759 * systime.h (Time): Define only if emacs is defined.
17760 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
17761 where the include path doesn't have X11/X.h by default. See
17762 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
17764 2011-05-20 Kenichi Handa <handa@m17n.org>
17766 * composite.c (find_automatic_composition): Fix previous change.
17768 2011-05-20 Glenn Morris <rgm@gnu.org>

17799 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
17801 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
17803 Fix some integer overflow issues, such as string length overflow.
17805 * insdel.c (count_size_as_multibyte): Check for string overflow.
17807 * character.c (lisp_string_width): Check for string overflow.
17808 Use EMACS_INT, not int, for string indexes and lengths; in
17809 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
17810 the resulting string length overflows an EMACS_INT; instead,
17811 report a string overflow if no precision given. When checking for
17812 precision exhaustion, use a check that cannot possibly have
17813 integer overflow. (Bug#8675)
17814 * character.h (lisp_string_width): Adjust to new signature.
17816 * alloc.c (string_overflow): New function.
17817 (Fmake_string): Use it. This doesn't change behavior, but saves
17818 a few bytes and will simplify future changes.
17819 * character.c (string_escape_byte8): Likewise.
17820 * lisp.h (string_overflow): New decl.
17822 Fixups, following up to the user-interface timestamp change.
17823 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
17824 for UI timestamps, instead of unsigned long.
17825 * msdos.c (mouse_get_pos): Likewise.
17826 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
17827 * w32gui.h (Time): Define by including "systime.h" rather than by
17828 declaring it ourselves. (Bug#8664)
17830 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
17831 * image.c (clear_image_cache): Likewise.
17833 * term.c (term_mouse_position): Don't assume time_t wraparound.
17835 Be more systematic about user-interface timestamps.
17836 Before, the code sometimes used 'Time', sometimes 'unsigned long',
17837 and sometimes 'EMACS_UINT', to represent these timestamps.
17838 This change causes it to use 'Time' uniformly, as that's what X uses.
17839 This makes the code easier to follow, and makes it easier to catch
17840 integer overflow bugs such as Bug#8664.
17841 * frame.c (Fmouse_position, Fmouse_pixel_position):
17842 Use Time, not unsigned long, for user-interface timestamps.
17843 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
17844 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
17845 * keyboard.h (last_event_timestamp): Likewise.
17846 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
17847 * menu.h (xmenu_show): Likewise.
17848 * term.c (term_mouse_position): Likewise.
17849 * termhooks.h (struct input_event.timestamp): Likewise.
17850 (struct terminal.mouse_position_hook): Likewise.
17851 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
17852 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
17853 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
17854 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
17855 what it was before.
17856 * menu.h, termhooks.h: Include "systime.h", for Time.
17858 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
17859 Don't assume that the difference between two unsigned long values
17860 can fit into an integer. At this point, we know button_down_time
17861 <= event->timestamp, so the difference must be nonnegative, so
17862 there's no need to cast the result if double-click-time is
17863 nonnegative, as it should be; check that it's nonnegative, just in
17864 case. This bug is triggered when events are more than 2**31 ms
17865 apart (about 25 days). (Bug#8664)
17867 * xselect.c (last_event_timestamp): Remove duplicate decl.
17868 (x_own_selection): Remove needless cast to unsigned long.
17870 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
17871 that always fit in int. Use a sentinel instead of a counter, to
17872 avoid a temp and to allay GCC's concerns about possible int overflow.
17873 * frame.h (struct frame): Use int for menu_bar_items_used
17874 instead of EMACS_INT, since it always fits in int.
17876 * menu.c (grow_menu_items): Check for int overflow.
17878 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
17880 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
17881 Before, the code was not consistent. These values cannot exceed
17882 2**31 - 1 so there's no need to make them unsigned.
17883 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
17884 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
17885 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
17887 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
17889 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
17890 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
17891 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
17892 presumably because the widths might not match.
17894 * window.c (size_window): Avoid needless test at loop start.
17896 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
17898 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
17900 2011-05-12 Drew Adams <drew.adams@oracle.com>
17902 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
17904 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17906 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
17907 `width' to `bar_area_x' and `bar_area_width', respectively.
17908 (x_scroll_run): Take account of fringe background extension.
17910 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
17911 Rename local vars `left' and `width' to `bar_area_x' and
17912 `bar_area_width', respectively.
17913 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
17914 background extension.
17916 2011-05-10 Jim Meyering <meyering@redhat.com>
17918 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
17920 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
17922 * image.c (Finit_image_library): Return t for built-in image types,
17923 like pbm and xbm. (Bug#8640)
17925 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
17927 * w32menu.c (set_frame_menubar): Fix submenu allocation.
17929 2011-05-07 Eli Zaretskii <eliz@gnu.org>
17931 * w32console.c (Fset_screen_color): Doc fix.
17932 (Fget_screen_color): New function.
17933 (syms_of_ntterm): Defsubr it.
17935 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
17936 unlink the temporary file if Fcall_process didn't create it in the
17938 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
17939 child process will be redirected to a file specified with `:file'.
17940 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
17941 cue to call_process_cleanup not to close that handle.
17943 2011-05-07 Ben Key <bkey76@gmail.com>
17945 * makefile.w32-in: The bootstrap-temacs rule now makes use of
17946 one of two shell specific rules, either bootstrap-temacs-CMD or
17947 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
17948 to the previous implementation of the bootstrap-temacs rule.
17949 The bootstrap-temacs-CMD rule is similar to the previous
17950 implementation of the bootstrap-temacs rule except that it
17951 makes use of the ESC_CFLAGS variable instead of the CFLAGS
17954 These changes, along with some changes to nt/configure.bat,
17955 nt/gmake.defs, and nt/nmake.defs, are required to extend my
17956 earlier fix to add support for --cflags and --ldflags options
17957 that include quotes so that it works whether make uses cmd or
17960 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
17962 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
17963 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
17965 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
17966 a string. Handle both cases.
17967 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
17968 (Fdbus_register_method): Use Qinvalid_function.
17970 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17972 * makefile.w32-in: Update dependencies.
17973 (LISP_H): Add inttypes.h and stdin.h.
17974 (PROCESS_H): Add unistd.h.
17976 2011-05-06 Eli Zaretskii <eliz@gnu.org>
17978 * lread.c: Include limits.h (fixes the MS-Windows build broken by
17979 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
17981 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
17983 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
17985 * term.c (vfatal): Remove stray call to va_end.
17986 It's not needed and the C Standard doesn't allow it here anyway.
17988 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
17989 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
17991 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
17994 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
17996 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17998 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18000 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18002 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18004 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18005 * charset.c (Fdefine_charset_internal): Don't initialize
18006 charset.code_space[15]. The value was garbage, on hosts with
18007 32-bit int (Bug#8600).
18009 * lread.c (read_integer): Be more consistent with string-to-number.
18010 Use string_to_number to do the actual conversion; this avoids
18011 rounding errors and fixes some other screwups. Without this fix,
18012 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18013 (digit_to_number): Move earlier, for benefit of read_integer.
18014 Return -1 if the digit is out of range for the base, -2 if it is
18015 not a digit in any supported base. (Bug#8602)
18017 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18019 * dispnew.c (scrolling_window): Return 1 if we scrolled,
18020 to match comment at start of function. This also removes a
18021 GCC warning about overflow in a 32+64-bit port.
18023 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
18025 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
18026 Reported by Stefan Monnier in
18027 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
18028 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18029 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
18031 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
18032 (EMACS_UINTPTR): Likewise, with uintptr_t.
18034 * lisp.h: Prefer 64-bit EMACS_INT if available.
18035 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
18036 on 32-bit hosts that have 64-bit int, so that they can access
18038 However, temporarily disable this change unless the temporary
18039 symbol WIDE_EMACS_INT is defined.
18041 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
18043 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
18044 This removes an assumption that EMACS_INT and long are the same
18045 width as pointers. The assumption is true for Emacs porting targets
18046 now, but we want to make other targets possible.
18047 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18048 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18049 In the rest of the code, change types of integers that hold casted
18050 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18051 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18052 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18053 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18054 No need to cast type when ORing.
18055 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18056 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18057 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18058 assume EMACS_INT is the same width as char *.
18059 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18060 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18061 Remove no-longer-needed casts.
18062 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18063 (xg_tool_bar_help_callback, xg_make_tool_item):
18064 Use EMACS_INTPTR to hold an integer
18065 that will be cast to void *; this can avoid a GCC warning
18066 if EMACS_INT is not the same width as void *.
18067 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18068 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18069 (current_message_1, set_message_1):
18070 Use a local to convert to proper width without a cast.
18071 * xmenu.c (dialog_selection_callback): Likewise.
18073 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18074 Also, don't assume VALBITS / RAND_BITS is less than 5,
18075 and don't rely on undefined behavior when shifting a 1 left into
18077 * lisp.h (get_random): Change signature to match.
18079 * lread.c (hash_string): Use size_t, not int, for hash computation.
18080 Normally we prefer signed values; but hashing is special, because
18081 it's better to use unsigned division on hash table sizes so that
18082 the remainder is nonnegative. Also, size_t is the natural width
18083 for hashing into memory. The previous code used 'int', which doesn't
18084 retain enough info to hash well into very large tables.
18085 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18087 * dbusbind.c: Don't possibly lose pointer info when converting.
18088 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18089 Use XPNTR rather than XHASH, so that the high-order bits of
18090 the pointer aren't lost when converting through void *.
18092 * eval.c (Fautoload): Don't double-shift a pointer.
18094 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18096 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18098 * gnutls.c (DEF_GNUTLS_FN):
18099 * image.c (DEF_IMGLIB_FN): Make function pointers static.
18101 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
18103 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
18106 2011-05-05 Eli Zaretskii <eliz@gnu.org>
18108 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
18109 New version that can reserve upto 2GB of heap space.
18111 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
18113 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
18115 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
18117 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
18118 `gnutls_certificate_set_x509_key_file'.
18120 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
18122 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
18123 Update dependencies.
18125 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18127 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
18128 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
18129 Remove unused parameter `fildes'.
18130 * process.c (read_process_output, send_process): Don't pass it.
18132 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18134 Fix previous change: the library cache is defined in w32.c.
18135 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
18136 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
18138 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18140 Implement dynamic loading of GnuTLS on Windows.
18142 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
18143 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
18144 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18147 * gnutls.c (Qgnutls_dll): Define.
18148 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
18149 (gnutls_*): Declare function pointers.
18150 (init_gnutls_functions): New function to initialize function pointers.
18151 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
18152 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
18153 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18154 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
18155 (emacs_gnutls_write, emacs_gnutls_read)
18156 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
18157 (Fgnutls_available_p): New function.
18158 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
18159 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
18160 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
18162 * image.c: Include w32.h.
18163 (Vimage_type_cache): Delete.
18164 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
18165 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
18166 (w32_delayed_load): Move to w32.c.
18168 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
18170 * w32.c (QCloaded_from, Vlibrary_cache): Define.
18171 (w32_delayed_load): Move from image.c. When loading a library, record
18172 its filename in the :loaded-from property of the library id.
18173 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
18174 Initialize and staticpro them.
18175 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
18177 * process.c: Include lisp.h before w32.h, not after.
18178 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
18179 instead of gnutls_record_check_pending.
18181 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
18183 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
18185 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
18186 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
18189 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
18191 * xterm.c (x_set_frame_alpha): Do not set property on anything
18192 else than FRAME_X_OUTER_WINDOW (Bug#8608).
18194 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18196 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
18198 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18200 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
18201 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
18202 (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)

18207 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
18208 (Qgnutls_bootprop_callbacks_verify): Make static.
18210 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
18212 * callproc.c: Indentation fixup.
18214 * sysdep.c (wait_for_termination_1): Make static.
18215 (wait_for_termination, interruptible_wait_for_termination):
18216 Move after wait_for_termination_1.
18218 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
18220 * sysdep.c (interruptible_wait_for_termination): New function
18221 which is like wait_for_termination, but allows keyboard
18224 * callproc.c (Fcall_process): Add (:file "file") as an option for
18226 (Fcall_process_region): Ditto.
18228 2011-04-30 Eli Zaretskii <eliz@gnu.org>
18230 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
18231 rather than `XVECTOR (FOO)->size'.
18233 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18234 inttypes.h, as a gnulib replacement is used if it not available in
18237 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18239 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
18240 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
18241 of MOST_POSITIVE_FIXNUM. (Bug#8528)
18243 * coding.c (coding_alloc_by_realloc): Error out if destination
18244 will grow beyond MOST_POSITIVE_FIXNUM.
18245 (decode_coding_emacs_mule): Abort if there isn't enough place in
18246 charbuf for the composition carryover bytes. Reserve an extra
18247 space for up to 2 characters produced in a loop.
18248 (decode_coding_iso_2022): Abort if there isn't enough place in
18249 charbuf for the composition carryover bytes.
18251 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18253 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
18254 aborting when %lld or %lll format is passed.
18255 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
18256 %llo or %llx format is passed. (Bug#8545)
18258 * window.c (window_scroll_line_based): Use a marker instead of
18259 simple variables to record original value of point. (Bug#7952)
18261 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18262 produced by %s or %c overflows available buffer space. (Bug#8545)
18264 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18266 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
18267 (SIZE_MAX): Move defn after all includes, as they might #define it.
18269 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18271 * w32.c (init_environment): Warn about defaulting HOME to C:\.
18273 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18275 * keyboard.c (Qdelayed_warnings_hook): Define.
18276 (command_loop_1): Run `delayed-warnings-hook'
18277 if Vdelayed_warnings_list is non-nil.
18278 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
18279 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
18281 2011-04-28 Eli Zaretskii <eliz@gnu.org>
18283 * doprnt.c (doprnt): Don't return value smaller than the buffer
18284 size if the message was truncated. (Bug#8545).
18286 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18288 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
18289 (Fx_window_property): #if-0 the whole functions, not just the bodies.
18291 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18293 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
18295 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
18297 * makefile.w32-in: Update dependencies.
18299 2011-04-27 Eli Zaretskii <eliz@gnu.org>
18301 Improve `doprnt' and its usage. (Bug#8545)
18302 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18303 `format_end'. Remove support for %l as a conversion specifier.
18304 Don't use xrealloc. Improve diagnostics when the %l size modifier
18305 is used. Update the commentary.
18307 * eval.c (verror): Simplify calculation of size_t.
18309 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18312 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18314 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18317 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18319 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18320 This makes this file independent of the recent pseudovector change.
18322 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18324 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18326 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18327 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18328 Remove unused local.
18329 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18331 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18332 GCC 4.6.0 optimizes based on type-based alias analysis.
18333 For example, if b is of type struct buffer * and v of type struct
18334 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18335 != &v->size, and therefore "v->size = 1; b->size = 2; return
18336 v->size;" must therefore return 1. This assumption is incorrect
18337 for Emacs, since it type-puns struct Lisp_Vector * with many other
18338 types. To fix this problem, this patch adds a new type struct
18339 vectorlike_header that documents the constraints on layout of vectors
18340 and pseudovectors, and helps optimizing compilers not get fooled
18341 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18342 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18343 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18345 (XSETPVECTYPE): Rewrite in terms of new macro.
18346 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18347 This is a bit clearer, and further avoids the possibility of
18348 undesirable aliasing.
18349 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18350 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18351 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18352 since Lisp_Subr is a special case (no "next" field).
18353 (ASIZE): Now uses header.size rather than size.
18354 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18355 to avoid the hassle of writing XVECTOR (foo)->header.size.
18356 (struct vectorlike_header): New type.
18357 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18358 object, to help avoid aliasing.
18359 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18360 (SUBRP): Likewise, since Lisp_Subr is a special case.
18361 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18362 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18363 (struct Lisp_Hash_Table): Combine first two members into a single
18364 struct vectorlike_header member. All uses of "size" and "next" members
18365 changed to be "header.size" and "header.next".
18366 * buffer.h (struct buffer): Likewise.
18367 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18368 * frame.h (struct frame): Likewise.
18369 * process.h (struct Lisp_Process): Likewise.
18370 * termhooks.h (struct terminal): Likewise.
18371 * window.c (struct save_window_data, struct saved_window): Likewise.
18372 * window.h (struct window): Likewise.
18373 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18374 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18375 * buffer.c (init_buffer_once): Likewise.
18376 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18378 * process.c (Fformat_network_address): Use local var for size,
18381 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18383 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18384 * data.c (atof): Remove decl; no longer used or needed.
18385 (digit_to_number): Move to lread.c.
18386 (Fstring_to_number): Use new string_to_number function, to be
18387 consistent with how the Lisp reader treats infinities and NaNs.
18388 Do not assume that floating-point numbers represent EMACS_INT
18389 without losing information; this is not true on most 64-bit hosts.
18390 Avoid double-rounding errors, by insisting on integers when
18391 parsing non-base-10 numbers, as the documentation specifies.
18392 * lisp.h (string_to_number): New decl, replacing ...
18393 (isfloat_string): Remove.
18394 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18395 (read1): Do not accept +. and -. as integers; this
18396 appears to have been a coding error. Similarly, do not accept
18397 strings like +-1e0 as floating point numbers. Do not report
18398 overflow for integer overflows unless the base is not 10 which
18399 means we have no simple and reliable way to continue.
18400 Break out the floating-point parsing into a new
18401 function string_to_number, so that Fstring_to_number parses
18402 floating point numbers consistently with the Lisp reader.
18403 (digit_to_number): Move here from data.c. Make it static inline.
18404 (E_CHAR, EXP_INT): Remove, replacing with ...
18405 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18406 (string_to_number): New function, replacing isfloat_string.
18407 This function checks for valid syntax and produces the resulting
18408 Lisp float number too. Rework it so that string-to-number
18409 no longer mishandles examples like "1.0e+". Use strtoumax,
18410 so that overflow for non-base-10 numbers is reported only when
18411 there's no portable and simple way to convert to floating point.
18413 * textprop.c (set_text_properties_1): Rewrite for clarity,
18414 and to avoid GCC warning about integer overflow.
18416 * intervals.h (struct interval): Use EMACS_INT for members
18417 where EMACS_UINT might cause problems. See
18418 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18419 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18420 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18422 (offset_intervals): Tell GCC not to worry about length overflow
18423 when negating a negative length.
18425 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
18426 (overrun_check_free): Likewise.
18428 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
18429 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
18432 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18433 (gnutls_make_error): Rename local to avoid shadowing.
18434 (gnutls_emacs_global_deinit): ifdef out; not used.
18435 (Fgnutls_boot): Use const for pointer to readonly storage.
18436 Comment out unused local. Fix pointer signedness problems.
18438 * lread.c (openp): Don't stuff size_t into an 'int'.
18439 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
18440 about possible signed overflow.
18442 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18443 (GDK_KEY_g): Don't define if already defined.
18444 (xg_prepare_tooltip): Avoid pointer signedness problem.
18445 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
18447 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
18448 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
18450 * xfns.c (Fx_window_property): Simplify a bit,
18451 to make a bit faster and to avoid GCC 4.6.0 warning.
18452 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
18454 * fns.c (internal_equal): Don't assume size_t fits in int.
18456 * alloc.c (compact_small_strings): Tighten assertion a little.
18458 Replace pEd with more-general pI, and fix some printf arg casts.
18459 * lisp.h (pI): New macro, generalizing old pEd macro to other
18460 conversion specifiers. For example, use "...%"pI"d..." rather
18461 than "...%"pEd"...".
18462 (pEd): Remove. All uses replaced with similar uses of pI.
18463 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
18464 * alloc.c (check_pure_size): Don't overflow by converting size to int.
18465 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
18466 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
18467 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
18468 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
18469 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
18471 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
18472 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
18473 * print.c (safe_debug_print, print_object): Likewise.
18474 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
18476 Use pI instead of if-then-else-abort. Use %p to avoid casts,
18477 avoiding the 0 flag, which is not portable.
18478 * process.c (Fmake_network_process): Use pI to avoid cast.
18479 * region-cache.c (pp_cache): Likewise.
18480 * xdisp.c (decode_mode_spec): Likewise.
18481 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
18482 behavior on 64-bit hosts with printf arg.
18483 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
18484 (x_stop_queuing_selection_requests): Likewise.
18485 (x_get_window_property): Don't truncate byte count to an 'int'
18488 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
18489 here, since it parses constructs like leading '-' and spaces,
18490 which are not wanted; and it overflows with large numbers.
18491 Instead, simply match F[0-9]+, which is what is wanted anyway.
18493 * alloc.c: Remove unportable assumptions about struct layout.
18494 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
18495 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
18496 (allocate_vectorlike, make_pure_vector): Use the new macros,
18497 plus offsetof, to remove unportable assumptions about struct layout.
18498 These assumptions hold on all porting targets that I know of, but
18499 they are not guaranteed, they're easy to remove, and removing them
18500 makes further changes easier.
18502 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
18503 This doesn't fix a bug but makes the code clearer.
18504 (string_overrun_cookie): Now const. Use initializers that
18505 don't formally overflow signed char, to avoid warnings.
18506 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
18507 can cause Emacs to crash when string overrun checking is enabled.
18508 (allocate_buffer): Don't assume sizeof (struct buffer) is a
18509 multiple of sizeof (EMACS_INT); it need not be, if
18510 alignof(EMACS_INT) < sizeof (EMACS_INT).
18511 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18513 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
18515 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
18517 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
18519 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
18520 supposed to be handshaking. (Bug#8556)
18521 Reported by Paul Eggert <eggert@cs.ucla.edu>.
18523 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
18525 * lisp.h (Qdebug): List symbol.
18526 * eval.c (Qdebug): Restore global linkage.

18528 (handle_user_signal): Break into debugger when debug-on-event
18529 matches the current signal symbol.
18531 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
18533 * alloc.c (check_sblock, check_string_bytes)
18534 (check_string_free_list): Convert to standard C.
18536 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
18538 * w32.c (emacs_gnutls_push): Fix typo.
18540 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18542 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18543 "cast to pointer from integer of different size".
18545 Improve doprnt and its use in verror. (Bug#8545)
18546 * doprnt.c (doprnt): Document the set of format control sequences
18547 supported by the function. Use SAFE_ALLOCA instead of always
18550 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18551 is one byte too soon. Don't use xrealloc; instead xfree and
18554 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18556 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
18559 * gnutls.c: Renamed global_initialized to
18560 gnutls_global_initialized. Added internals for the
18561 :verify-hostname-error, :verify-error, and :verify-flags
18562 parameters of `gnutls-boot' and documented those parameters in the
18563 docstring. Start callback support.
18564 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18565 unless a fatal error occurred. Call gnutls_alert_send_appropriate
18566 on error. Return error code.
18567 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
18568 (emacs_gnutls_read): Likewise.
18569 (Fgnutls_boot): Return handshake error code.
18570 (emacs_gnutls_handle_error): New function.
18571 (wsaerror_to_errno): Likewise.

18576 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
18577 (emacs_gnutls_push): Likewise.
18579 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
18581 * process.c (wait_reading_process_output): Check if GnuTLS
18582 buffered some data internally if no FDs are set for TLS
18585 * makefile.w32-in (OBJ2): Add gnutls.$(O).

18620 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
18622 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
18625 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
18626 changes in globals.h immediately force recompilation.
18627 (TAGS): Depend on $(CURDIR)/m/intel386.h and
18628 $(CURDIR)/s/ms-w32.h.
18629 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

18632 (syms_of_character): Don't defsubr it.
18633 <char-direction-table>: Deleted.
18635 2011-04-23 Eli Zaretskii <eliz@gnu.org>
18637 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
18638 * doprnt.c: Include limits.h.
18639 (SIZE_MAX): New macro.
18640 (doprnt): Return a size_t value. 2nd arg is now size_t.
18641 Many local variables are now size_t instead of int or unsigned.
18642 Improve overflow protection. Support `l' modifier for integer
18643 conversions. Support %l conversion. Don't assume an EMACS_INT
18644 argument for integer conversions and for %c.
18646 * lisp.h (doprnt): Restore prototype.
18648 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
18649 $(SRC)/character.h.
18651 * Makefile.in (base_obj): Add back doprnt.o.
18653 * deps.mk (doprnt.o): Add back prerequisites.
18654 (callint.o): Depend on character.h.
18656 * eval.c (internal_lisp_condition_case): Include the handler
18657 representation in the error message.
18658 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
18659 when breaking from the loop.
18661 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
18663 * callint.c (Fcall_interactively): When displaying error message
18664 about invalid control letter, pass the character's codepoint, not

18871 ns_descriptor_to_entity that were caused by using free to
18872 deallocate memory blocks that were allocated by xmalloc (via

18894 * process.c (send_process): Adjust to the new signatures of
18895 emacs_write and emacs_gnutls_write. Do not attempt to store

19238 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
19239 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
19240 was inaccessible from Lisp.
19241 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
19242 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
19244 alloc.c: Import and export fewer symbols, and remove unused items.
19245 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING

19262 * xdisp.c (message_enable_multibyte): Now static.
19264 Declare Lisp_Object Q* variables to be 'static' if not exported.
19265 This makes it easier for human readers (and static analyzers)
19266 to see whether these variables are used from other modules.
19267 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

19280 * lisp.h (DEFINE_FUNC): Make sname 'static'.
19282 Make Emacs functions such as Fatom 'static' by default.
19283 This makes it easier for human readers (and static analyzers)
19284 to see whether these functions can be called from other modules.
19285 DEFUN now defines a static function. To make the function external
19286 so that it can be used in other C modules, use the new macro DEFUE.

19292 Remove decls, since these functions are now static.
19293 (Funintern, Fget_internal_run_time): New decls, since these functions
19294 were already external.
19296 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

19304 Mark functions with DEFUE instead of DEFUN,
19305 if they are used in other modules.
19306 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
19307 decls for now-static functions.
19308 * buffer.h (Fdelete_overlay): Remove decl.

19344 2011-04-13 Eli Zaretskii <eliz@gnu.org>
19346 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
19347 when at ZV. (Bug#8487)
19349 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>

19359 * alloc.c (overrun_check_malloc, overrun_check_realloc)
19360 (overrun_check_free): Protoize.
19362 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
19364 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
19365 since callers should never pass a negative size.
19366 Change the signature to match that of plain 'read' and 'write'; see
19367 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
19368 * lisp.h: Update prototypes of emacs_write and emacs_read.
19370 2011-04-11 Eli Zaretskii <eliz@gnu.org>
19372 * xdisp.c (redisplay_window): Don't try to determine the character
19373 position of the scroll margin if the window start point w->startp
19374 is outside the buffer's accessible region. (Bug#8468)
19376 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19378 Fix write-region and its subroutines for buffers > 2GB.
19379 * fileio.c (a_write, e_write): Modify declaration of arguments and
19380 local variables to support buffers larger than 2GB.
19381 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
19383 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
19384 argument, local variables, and return value.
19386 * lisp.h: Update prototypes of emacs_write and emacs_read.
19388 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
19390 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
19392 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
19394 Fix more problems found by GCC 4.6.0's static checks.
19396 * xdisp.c (vmessage): Use a better test for character truncation.
19398 * charset.c (load_charset_map): <, not <=, for optimization,
19399 and to avoid potential problems with integer overflow.
19400 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
19401 * casetab.c (set_identity, shuffle): Likewise.
19402 * editfns.c (Fformat): Likewise.
19403 * syntax.c (skip_chars): Likewise.
19405 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
19406 This also lets GCC 4.6.0 generate slightly better loop code.
19408 * callint.c (Fcall_interactively): <, not <=, for optimization.
19409 (Fcall_interactively): Count the number of arguments produced,
19410 not the number of arguments given. This is simpler and lets GCC
19411 4.6.0 generate slightly better code.
19413 * ftfont.c: Distingish more carefully between FcChar8 and char.
19414 The previous code passed unsigned char * to a functions like
19415 strlen and xstrcasecmp that expect char *, which does not
19416 conform to the C standard.
19417 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19418 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19419 char * when the C standard requires it.
19421 * keyboard.c (read_char): Remove unused var.
19423 * eval.c: Port to Windows vsnprintf (Bug#8435).
19424 Include <limits.h>.
19425 (SIZE_MAX): Define if the headers do not.
19426 (verror): Do not give up if vsnprintf returns a negative count.
19427 Instead, grow the buffer. This ports to Windows vsnprintf, which
19428 does not conform to C99. Problem reported by Eli Zaretskii.
19429 Also, simplify the allocation scheme, by avoiding the need for
19430 calling realloc, and removing the ALLOCATED variable.
19432 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
19434 Remove invocations of doprnt, as Emacs now uses vsnprintf.
19435 But keep the doprint source code for now, as we might revamp it
19436 and use it again (Bug#8435).
19437 * lisp.h (doprnt): Remove.
19438 * Makefile.in (base_obj): Remove doprnt.o.
19439 * deps.mk (doprnt.o): Remove.
19441 error: Print 32- and 64-bit integers portably (Bug#8435).
19442 Without this change, on typical 64-bit hosts error ("...%d...", N)
19443 was used to print both 32- and 64-bit integers N, which relied on
19444 undefined behavior.
19445 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
19446 * lisp.h (error, verror): Mark as printf-like functions.
19447 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
19448 Report overflow in size calculations when allocating printf buffer.
19449 Do not truncate output string at its first null byte.
19450 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
19451 Truncate the output at a character boundary, since vsnprintf does not
19453 * charset.c (check_iso_charset_parameter): Convert internal
19454 character to string before calling 'error', since %c now has the
19456 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
19457 overflow when computing char to be passed to 'error'. Do not
19458 pass Lisp_Object to 'error'; pass the integer instead.
19459 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
19460 formatted with plain %d.
19462 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
19464 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
19466 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
19468 * xterm.c (x_catch_errors): Remove duplicate declaration.
19470 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
19472 * xdisp.c, lisp.h (message_nolog): Remove; unused.
19474 2011-04-10 Jim Meyering <meyering@redhat.com>
19476 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
19477 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
19478 return ssize_t not "int", and use size_t as the buffer length.
19479 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
19480 * gnutls.h: Update declarations.
19481 * process.c (read_process_output): Use ssize_t, to match.
19482 (send_process): Likewise.
19484 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19486 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
19488 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19490 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
19491 Use unsigned char, to match FcChar8 type definition.
19493 * xterm.c (handle_one_xevent):
19494 * xmenu.c (create_and_show_popup_menu):
19495 * xselect.c (x_decline_selection_request)
19496 (x_reply_selection_request): Avoid type-punned deref of X events.
19498 2011-04-09 Eli Zaretskii <eliz@gnu.org>
19500 Fix some uses of `int' instead of EMACS_INT.
19501 * search.c (string_match_1, fast_string_match)
19502 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
19503 (scan_buffer, find_next_newline_no_quit)
19504 (find_before_next_newline, search_command, Freplace_match)
19505 (Fmatch_data): Make some `int' variables be EMACS_INT.
19507 * xdisp.c (display_count_lines): 3rd argument and return value now
19508 EMACS_INT. All callers changed.
19509 (pint2hrstr): Last argument is now EMACS_INT.
19511 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
19512 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
19513 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

19524 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
19525 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
19527 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
19528 (encode_invocation_designation): Last argument P_NCHARS is now
19530 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
19531 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
19533 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
19536 * ccl.c (Fccl_execute_on_string): Declare some variables
19539 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)

19554 instead of using internal_with_output_to_temp_buffer.
19555 (Qhelp_form_show): New var.
19556 (syms_of_keyboard): Use DEFSYM macro.
19558 * print.c (internal_with_output_to_temp_buffer): Function deleted.

19571 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19573 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
19575 Fix more problems found by GCC 4.6.0's static checks.
19577 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.

19581 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
19583 * xdisp.c (vmessage): Mark as a printf-like function.
19585 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

19590 printf-like functions.
19591 (tiff_load): Add casts to remove these marks before passing them
19592 to system-supplied API.
19594 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19596 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19597 This avoids several warnings with gcc -Wstrict-overflow.
19598 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19599 directly, rather than having caller test rule sign. This avoids
19600 some unnecessary tests.
19601 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19602 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19603 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19605 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19606 (xfont_open): Avoid unnecessary tests.
19608 * composite.c (composition_gstring_put_cache): Use unsigned integer.
19610 * composite.h, composite.c (composition_gstring_put_cache):
19611 Use EMACS_INT, not int, for length.
19613 * composite.h (COMPOSITION_DECODE_REFS): New macro,
19614 breaking out part of COMPOSITION_DECODE_RULE.
19615 (COMPOSITION_DECODE_RULE): Use it.
19616 * composite.c (get_composition_id): Remove unused local vars,
19617 by using the new macro.
19619 * textprop.c (set_text_properties_1): Change while to do-while,
19620 since the condition is always true at first.
19622 * intervals.c (graft_intervals_into_buffer): Mark var as used.
19623 (interval_deletion_adjustment): Return unsigned value.
19626 * process.c (list_processes_1, create_pty, read_process_output):
19627 (exec_sentinel): Remove vars that were set but not used.
19628 (create_pty): Remove unnecessary "volatile"s.
19629 (Fnetwork_interface_info): Avoid possibility of int overflow.
19630 (read_process_output): Do adaptive read buffering even if carryover.
19631 (read_process_output): Simplify nbytes computation if buffered.

19636 (update_syntax_table): Use unsigned instead of int.
19638 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
19639 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
19640 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
19642 * print.c (print_error_message): Avoid int overflow.
19644 * font.c (font_list_entities): Redo for clarity,
19645 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
19647 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
19648 (font_score): Avoid potential overflow in diff calculation.
19650 * fns.c (substring_both): Remove var that is set but not used.
19651 (sxhash): Redo loop for clarity and to avoid wraparound warning.
19653 * eval.c (funcall_lambda): Rename local to avoid shadowing.
19655 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
19656 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
19657 can always succeed if overflow has undefined behavior.
19659 * search.c (boyer_moore, wordify): Remove vars set but not used.
19660 (wordify): Omit three unnecessary tests.
19662 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
19663 All callers changed. This avoids the need for an unused var.
19665 * casefiddle.c (casify_region): Remove var that is set but not used.
19667 * dired.c (file_name_completion): Remove var that is set but not used.
19669 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
19671 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
19672 (Finsert_file_contents): Remove unnecessary code checking fd.
19674 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
19675 Check for integer overflow on size calculations.
19677 * buffer.c (Fprevious_overlay_change): Remove var that is set
19680 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
19681 Remove vars that are set but not used.
19682 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
19683 (timer_check_2): Mark vars as initialized.
19685 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
19687 * image.c (lookup_image): Remove var that is set but not used.
19688 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
19690 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19691 that are set but not used.
19693 * xfns.c (make_invisible_cursor): Don't return garbage
19694 if XCreateBitmapFromData fails (Bug#8410).
19696 * xselect.c (x_get_local_selection, x_handle_property_notify):
19697 Remove vars that are set but not used.
19699 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
19700 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
19702 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
19703 Remove var that is set but not used.
19704 (scroll_bar_windows_size): Now size_t, not int.
19705 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
19706 Check for overflow.
19708 * xfaces.c (realize_named_face): Remove vars that are set but not used.
19709 (map_tty_color) [!defined MSDOS]: Likewise.
19711 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
19713 * coding.c: Remove vars that are set but not used.
19714 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
19715 All callers changed.
19716 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
19717 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
19718 (decode_coding_charset): Remove vars that are set but not used.
19720 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
19721 that is set but not used.
19723 * print.c (print_object): Remove var that is set but not used.
19725 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
19726 The gnulib version avoids calling malloc in the usual case,
19727 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
19728 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
19729 * filelock.c (current_lock_owner): Likewise.
19730 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
19731 * sysdep.c: Include allocator.h, careadlinkat.h.
19732 (emacs_no_realloc_allocator): New static constant.
19733 (emacs_readlink): New function.
19734 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
19735 ../lib/careadlinkat.h.
19737 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
19739 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
19740 first non-nil return value).
19742 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
19744 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
19745 if not defined (Bug#8403).
19747 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19749 * xdisp.c (display_count_lines): Remove parameter `start',
19750 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19751 (get_char_face_and_encoding): Remove parameter `multibyte_p',
19752 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

19754 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
19755 and thereabouts. All callers changed.
19756 (get_per_char_metric): Remove parameter `f', unused since
19757 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
19759 2011-04-02 Jim Meyering <meyering@redhat.com>
19761 do not dereference NULL upon failed strdup
19762 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
19763 (ns_get_family): Likewise.
19765 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19767 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
19769 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
19771 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
19774 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
19776 Add lexical binding.
19778 * window.c (Ftemp_output_buffer_show): New fun.
19779 (Fsave_window_excursion):
19780 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
19782 * lread.c (lisp_file_lexically_bound_p): New function.
19783 (Fload): Bind Qlexical_binding.
19784 (readevalloop): Remove `evalfun' arg.
19785 Bind Qinternal_interpreter_environment.
19786 (Feval_buffer): Bind Qlexical_binding.
19787 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
19789 (syms_of_lread): Declare `lexical-binding'.
19791 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
19793 * keyboard.c (eval_dyn): New fun.
19794 (menu_item_eval_property): Use it.
19796 * image.c (parse_image_spec): Use Ffunctionp.
19798 * fns.c (concat, mapcar1): Accept byte-code-functions.
19800 * eval.c (Fsetq): Handle lexical vars.
19801 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
19802 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
19803 (FletX, Flet): Obey lexical binding.
19804 (Fcommandp): Handle closures.
19805 (Feval): New `lexical' arg.
19806 (eval_sub): New function extracted from Feval. Use it almost
19807 everywhere where Feval was used. Look up vars in lexical env.
19809 (Ffunctionp): Move from subr.el.
19810 (Ffuncall): Handle closures.
19811 (apply_lambda): Remove `eval_flags'.
19812 (funcall_lambda): Handle closures and new byte-code-functions.
19813 (Fspecial_variable_p): New function.
19814 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
19815 but without exporting it to Lisp.
19817 * doc.c (Fdocumentation, store_function_docstring):
19818 * data.c (Finteractive_form): Handle closures.
19820 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
19823 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
19825 (exec_byte_code): New function extracted from Fbyte_code to handle new
19826 calling convention for byte-code-functions. Add new byte-codes.
19828 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
19830 * alloc.c (Fmake_symbol): Init new `declared_special' field.
19832 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19834 * xdisp.c (redisplay_internal): Fix prototype.
19836 2011-03-31 Eli Zaretskii <eliz@gnu.org>
19838 * xdisp.c (SCROLL_LIMIT): New macro.
19839 (try_scrolling): Use it when setting scroll_limit.
19840 Limit scrolling to 100 screen lines.
19841 (redisplay_window): Even when falling back on "recentering",
19842 position point in the window according to scroll-conservatively,
19843 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
19845 (try_scrolling): When point is above the window, allow searching
19846 as far as scroll_max, or one screenful, to compute vertical
19847 distance from PT to the scroll margin position. This prevents
19848 try_scrolling from unnecessarily failing when
19849 scroll-conservatively is set to a value slightly larger than the
19850 window height. Clean up the case of PT below the margin at bottom
19851 of window: scroll_max can no longer be INT_MAX. When aggressive
19852 scrolling is in use, don't let point enter the opposite scroll
19853 margin as result of the scroll.
19854 (syms_of_xdisp) <scroll-conservatively>: Document the
19855 threshold of 100 lines for never-recentering scrolling.
19857 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19859 * dispextern.h (move_it_by_lines):
19860 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
19861 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
19862 (message_log_check_duplicate): Remove parameters `prev_bol' and
19863 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19864 (redisplay_internal): Remove parameter `preserve_echo_area',
19865 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
19867 * indent.c (Fvertical_motion):
19868 * window.c (window_scroll_pixel_based, Frecenter):
19869 Don't pass `need_y_p' to `move_it_by_lines'.
19871 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
19873 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
19874 steal a few bits to be more compact.
19875 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
19876 Remove unneeded casts.
19878 * bytecode.c (Fbyte_code): CAR and CDR can GC.
19880 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
19882 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
19883 binding" message (bug#7967).
19885 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
19887 Fix more problems found by GCC 4.6.0's static checks.
19889 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
19890 Remove unused local var.
19892 * editfns.c (Fmessage_box): Remove unused local var.
19894 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
19895 (note_mode_line_or_margin_highlight, note_mouse_highlight):
19896 Omit unused local vars.
19897 * window.c (shrink_windows): Omit unused local var.
19898 * menu.c (digest_single_submenu): Omit unused local var.
19899 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
19900 Omit unused local var.
19902 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
19903 Don't assume string length fits in int.
19904 (keyremap_step, read_key_sequence): Use size_t for sizes.
19905 (read_key_sequence): Don't check last_real_key_start redundantly.
19907 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
19908 instead of alloca (Bug#8344).
19910 * eval.c (Fbacktrace): Don't assume nargs fits in int.
19911 (Fbacktrace_frame): Don't assume nframes fits in int.
19913 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
19915 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
19918 * term.c (produce_glyphless_glyph): Remove unnecessary test.
19920 * cm.c (calccost): Turn while-do into do-while, for clarity.
19922 * keyboard.c (syms_of_keyboard): Use the same style as later
19923 in this function when indexing through an array. This also
19924 works around GCC bug 48267.
19926 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
19928 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
19930 * chartab.c (sub_char_table_ref_and_range): Redo for slight
19931 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
19933 * keyboard.c, keyboard.h (num_input_events): Now size_t.
19934 This avoids undefined behavior on integer overflow, and is a bit
19935 more convenient anyway since it is compared to a size_t variable.
19937 Variadic C functions now count arguments with size_t, not int.
19938 This avoids an unnecessary limitation on 64-bit machines, which
19939 caused (substring ...) to crash on large vectors (Bug#8344).
19940 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
19941 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

19949 * fns.c (concat): Likewise.
19950 * frame.c (x_set_frame_parameters): Likewise.
19951 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
19952 0 if not found, not -1. All callers changed.
19954 * alloc.c (garbage_collect): Don't assume stack size fits in int.
19955 (stack_copy_size): Now size_t, not int.
19956 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
19958 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
19960 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
19961 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
19962 All callers changed.
19964 * lisp.h (multibyte_char_to_unibyte):
19965 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
19966 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
19967 * character.h (CHAR_TO_BYTE8):
19968 * cmds.c (internal_self_insert):
19969 * editfns.c (general_insert_function):
19970 * keymap.c (push_key_description):
19971 * search.c (Freplace_match):
19972 * xdisp.c (message_dolog, set_message_1): All callers changed.
19974 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
19976 * keyboard.c (safe_run_hook_funcall): New function.
19977 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
19978 don't set the hook to nil, but remove the offending function instead.
19979 (Qcommand_hook_internal): Remove, unused.
19980 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
19981 Vcommand_hook_internal.
19983 * eval.c (enum run_hooks_condition): Remove.
19984 (funcall_nil, funcall_not): New functions.
19985 (run_hook_with_args): Call each function through a `funcall' argument.
19986 Remove `cond' argument, now redundant.
19987 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
19988 (Frun_hook_with_args_until_failure): Adjust accordingly.
19989 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

20160 * callint.c (Fcall_interactively):
20161 * buffer.c (Fkill_all_local_variables):
20162 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
20164 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
20165 unconditionally since it does the check itself.
20167 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
20169 Fix more problems found by GCC 4.5.2's static checks.
20171 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20172 the first time through the loop, since we know p0 < p1 then.
20173 This also avoids a gcc -Wstrict-overflow warning.
20175 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20176 leading to a memory leak, possible in functions like
20177 load_charset_map_from_file that can allocate an unbounded number
20178 of objects (Bug#8318).
20180 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20181 that could (at least in theory) be that large.
20183 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20184 This is less likely to overflow, and avoids undefined behavior if
20185 overflow does occur. All callers changed. Use strtoul to scan
20186 for the unsigned long integer.
20187 (pint2hrstr): Simplify and tune code slightly.
20188 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

20203 * process.c (Fmake_network_process): Use socklen_t, not int,
20204 where POSIX says socklen_t is required in portable programs.
20205 This fixes a porting bug on hosts like 64-bit HP-UX, where
20206 socklen_t is wider than int (Bug#8277).
20207 (Fmake_network_process, server_accept_connection):
20208 (wait_reading_process_output, read_process_output):
20211 * process.c: Rename or move locals to avoid shadowing.

20221 Make tparam.h and terminfo.c consistent.
20222 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
20223 Include tparam.h instead, since it declares them.
20224 * cm.h (PC): Remove extern decl; tparam.h now does this.
20225 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
20226 * terminfo.c: Include tparam.h, to check interfaces.
20227 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20228 (tparam): Adjust signature to match interface in tparam.h;
20229 this removes some undefined behavior. Check that outstring and len
20230 are zero, which they always are with Emacs.
20231 * tparam.h (PC, BC, UP): New extern decls.
20233 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
20234 (xftfont_open): Rename locals to avoid shadowing.

20252 (composition_update_it): Mark var as initialized.
20253 (find_automatic_composition): Mark vars as initialized,
20254 with a FIXME (Bug#8290).

20260 (BUF_DEC_POS): Be more systematic about renaming local temporaries
20261 to avoid shadowing.

20273 Fix pointer signedness.
20274 (alsa_choose_format): Remove unused local var.
20275 (wav_play): Initialize a variable to 0, to prevent undefined
20276 behavior (Bug#8278).
20278 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
20280 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
20282 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
20283 clobbering (Bug#8298).
20284 * sysdep.c (sys_subshell): Likewise.
20285 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20287 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20288 This should get cleaned up, so that child_setup has the
20289 same signature on all platforms.
20291 * callproc.c (call_process_cleanup): Now static.
20292 (relocate_fd): Rename locals to avoid shadowing.
20294 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
20296 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
20297 not to be necessary, and produces flickering.
20299 2011-03-20 Glenn Morris <rgm@gnu.org>
20301 * config.in: Remove file.
20303 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

20354 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
20356 * deps.mk (unexalpha.o): Remove; unused.

20451 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
20452 (GC_STRING_CHARS): Remove; not used.
20453 (Fmemory_limit): Cast sbrk's returned value to char *.
20455 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
20456 avoids undefined behavior in theory.
20458 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
20460 Use functions, not macros, for up- and down-casing (Bug#8254).
20461 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20462 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
20463 to use the following functions instead of these macros.
20464 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
20465 EMACS_INT, since callers assume the returned value fits in int.
20466 (upcase1): Likewise, for UPCASE_TABLE.
20467 (uppercasep, lowercasep, upcase): New static inline functions.
20468 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
20469 the race-condition problem in the old DOWNCASE.
20471 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
20472 Rename locals to avoid shadowing.
20473 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
20474 (regex_compile, re_search_2, re_match_2_internal):
20475 Remove unused local vars.

20477 which gcc can warn about.
20478 (regex_compile, re_match_2_internal): Mark locals as initialized.
20479 (RETALLOC_IF): Define only if needed.
20480 (WORDCHAR_P): Likewise. This one is never needed, but is used
20481 only in a comment talking about a compiler bug, so put inside
20482 the #if 0 of that comment.
20483 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
20484 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
20487 * search.c (boyer_moore): Rename locals to avoid shadowing.
20488 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

20499 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.

20510 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
20511 New macros, so that the caller can use some names other than
20512 gcpro1, gcpro2, etc.
20513 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20515 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
20516 argument, for consistency with GCPRO2_VAR, etc: it is now the
20517 prefix of the variable, not the variable itself. All uses
20519 * dired.c (directory_files_internal, file_name_completion):
20520 Rename locals to avoid shadowing.
20522 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
20523 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
20524 dired.c's scmp function, had undefined behavior.
20525 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20526 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
20527 * buffer.h: ... to here, because these macros use current_buffer,
20528 and the new implementation with inline functions needs to have
20529 current_buffer in scope now, rather than later when the macros
20531 (downcase, upcase1): New static inline functions.
20532 (DOWNCASE, UPCASE1): Reimplement using these functions.
20533 This avoids undefined behavior in expressions like
20534 DOWNCASE (x) == DOWNCASE (y), which previously suffered
20535 from race conditions in accessing the global variables
20536 case_temp1 and case_temp2.
20537 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
20538 * lisp.h (case_temp1, case_temp2): Remove their decls.
20539 * character.h (ASCII_CHAR_P): Move from here ...
20540 * lisp.h: ... to here, so that the inline functions mentioned
20541 above can use them.
20543 * dired.c (directory_files_internal_unwind): Now static.
20545 * fileio.c (file_name_as_directory, directory_file_name):
20546 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
20548 (file_name_as_directory): Use const pointers when appropriate.
20549 (Fexpand_file_name): Likewise. In particular, newdir might
20550 point at constant storage, so make it a const pointer.
20551 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
20552 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
20554 (Fset_file_times, Finsert_file_contents, auto_save_error):

20559 to avoid shadowing.
20561 * marker.c (bytepos_to_charpos): Remove; unused.
20563 * lisp.h (verify_bytepos, count_markers): New decls,
20564 so that gcc does not warn that these functions aren't declared.
20566 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
20567 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
20568 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
20569 (copy_text): Remove unused local var.
20571 * filelock.c (within_one_second): Now static.
20572 (lock_file_1): Rename local to avoid shadowing.
20574 * buffer.c (fix_overlays_before): Mark locals as initialized.
20575 (fix_start_end_in_overlays): Likewise. This function should be
20576 simplified by using pointers-to-pointers, but that's a different
20578 (switch_to_buffer_1): Now static.
20579 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
20580 (report_overlay_modification): Rename locals to avoid shadowing.
20582 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
20583 Fix pointer signedness issue.
20584 (sys_subshell): Mark local as volatile if checking for lint,
20585 to suppress a gcc -Wclobbered warning that does not seem to be right.
20586 (MAXPATHLEN): Define only if needed.
20588 * process.c (serial_open, serial_configure): Move decls from here ...
20589 * systty.h: ... to here, so that they can be checked.
20591 * fns.c (get_random, seed_random): Move extern decls from here ...
20592 * lisp.h: ... to here, so that they can be checked.
20594 * sysdep.c (reset_io): Now static.
20595 (wait_for_termination_signal): Remove; unused.
20597 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
20598 (copy_keymap_item, append_key, push_text_char_description):
20600 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
20601 (DENSE_TABLE_SIZE): Remove; unused.
20602 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
20603 (describe_map_tree):
20604 Rename locals to avoid shadowing.
20606 * keyboard.c: Declare functions static if they are not used elsewhere.

20755 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
20756 reports time overflow. See
